Ophthalmic lens manufacturing system and manufacturing method

Technical field

The present invention relates to a technique for manufacturing an ophthalmic lens such as a contact lens and an intraocular lens, and in particular, when manufacturing a large number of ophthalmic lenses continuously, each ophthalmic lens has high accuracy and high efficiency. The present invention relates to an ophthalmic lens manufacturing system and manufacturing method that can be

Background art

[0002] Ophthalmic lenses such as contact lenses and intraocular lenses are manufactured using predetermined raw material monomers, but various manufacturing methods have been proposed conventionally. Specifically, a cutting method (also referred to as a race-cut method) for cutting and polishing 1 of lens blanks, which is an intermediate-formed product, or a mold for molding a male mold into a female mold into which raw materials are injected. The molding method (also called the cast molding method) and the spin casting method in which raw materials are spread and molded along the mold surface of the mold using centrifugal force are known. These manufacturing methods are selectively adopted according to the raw materials and the shape, dimensional accuracy, etc. of the intraocular lens required, and may be adopted in combination with each other in some cases.

[0003] Meanwhile, an ophthalmic lens is also a medical tool worn by the human eye, and a high degree of management is required with respect to its optical characteristics, shape, dimensions, sterilization state at the time of shipment, and the like. Particularly in recent years, many types of ophthalmic lenses having different optical characteristics and shapes have come to be provided so as to be able to respond to various requirements. Reliability and accuracy maintenance are becoming more highly demanded.

However, in the conventional management system for manufacturing an ophthalmic lens, it is still difficult to obtain sufficient reliability and accuracy. Further, in order to ensure management accuracy, there is a portion where manufacturing efficiency is sacrificed. there were.

That is, as illustrated in FIG. 11, the conventional management system prepares an instruction written with design data and the like on a piece of paper, and receives this instruction together with the ophthalmic lens in each manufacturing process. The person is supposed to check the description of the order by passing. However, such conventional In the case of the management system, the preparation and management of instructions required a lot of manpower and time, and there was a problem that the work was complicated and cumbersome. In particular, in recent years when various types of ophthalmic lenses have been produced in small amounts, as described above, strong work has become a heavy burden.

[0006] In addition, in order to simplify the work, generally, a plurality of ophthalmic lenses continuously manufactured according to the same standard are processed with a single instruction sheet. However, this will result in lot processing until management, and there will be no individual data such as inspection results after processing for each ophthalmic lens, so that the ophthalmic lenses can not be identified individually. there were. For this purpose, for example, even if it is found that there is a possibility that a problem may occur only with some of the ophthalmic lenses in a particular processing step, all ophthalmic lenses of all lots managed by one instruction sheet The production efficiency was very poor.

[0007] In recent years, it has also been proposed to provide instructions on the site of each process using a computer network. That is, a computer is installed at each site of each process of processing and inspection of an ophthalmic lens, and a network system in which those computers are connected to a computer for management is constructed. Then, through this computer network, the instruction is distributed to a computer installed at the site of each process of inspection and processing of management. At the site of each process, instruction data can be displayed on a monitor, eliminating the need to handle and manage complicated paper pieces.

[0008] Nevertheless, even if such computer-based instruction delivery was adopted, there was virtually no difference from the instruction using paper fragments, and the same problem was inherent. That is, it is not possible to individually manage the ophthalmic lenses manufactured continuously, and it is only necessary to unilaterally transmit the data of the instruction from the management side to the site of each process of processing and inspection. It is only Therefore, even if some ophthalmic lenses were found to have processing defects or bacterial contamination, they were forced to dispose of all ophthalmic lenses managed in one lot.

[0009] Force! In addition, problems unique to computer-based management systems also arise. It is an inevitable hardware and software aspect of computer systems. Is an accident of If a serious accident occurs, it will not be possible to obtain or even display the instruction manual, and the processing and inspection processes will stop completely, making the manufacturing operation extremely unstable. Production efficiency may decline.

[0010] It is also conceivable to manage the production of an ophthalmic lens using a bar code and a barcode reader as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 08-202410). That is, it is conceivable to manage each ophthalmic lens individually by attaching a bar code to a pallet or the like for transporting the ophthalmic lens in each process of processing and inspection.

However, even if the ophthalmic lens can be individually identified by the barcode, displaying the data of the instruction by the barcode itself can not be realized because of the large amount of data. There is no change in what you need as well.

[0012] On the contrary, for each separately identifiable eye lens, bar code data for identification is uploaded to the management computer at the site of each process, and then, the corresponding instruction is written. Management power to download data to the site computer of each process New need for processing power. In this way, for each ophthalmic lens, the amount of data sent and received by the computer in the field of all processes is enormous. Given that multiple production lines for ophthalmic lenses are arranged in parallel, and that many processing and inspection processes are set for each of these lines, the delay in data transmission and reception in the network and the delay to the computer for management It can be easily imagined that overload is a major problem.

[0013] Even if power can be stored in the computer for management even if the data of each individual ophthalmic lens can be stored, computer accidents are difficult to predict or avoid as described above. Therefore, when an accident occurs in the management computer, all information is unknown, and processing and inspection have to be stopped, and instability in manufacturing operations and a decline in manufacturing efficiency can not be avoided.

Further, at the site of each process, the design data and examination data of the ophthalmic lens existing at hand can not be browsed without access to the management computer one by one. For that reason, compared with the case where the instruction exists in a piece of paper, reading and confirmation are On the contrary, it will be troublesome. In particular, when there is a large amount of data communication and communication delays occur in the network, a waiting state for data transmission and reception for several tens of seconds or more occurs every processing and inspection work, resulting in a decrease in work efficiency. It has become possible that the system will become extremely difficult to use.

Disclosure of the invention

Problem that invention tries to solve

Here, the present invention has been made against the background as described above, and the problem to be solved by the present invention is the force of a piece of paper at the site of processing and inspection in a manufacturing line of an ophthalmic lens. Management of instructions, etc., and the processing instruction information such as standard values can be checked efficiently and accurately, and an excellent operation efficiency is achieved, a novel ophthalmic lens To provide a manufacturing system and method.

In addition, according to the present invention, it is possible to individually identify the ophthalmic lens in the intermediate processing state and the processed state, and individually manage the state of processing and inspection based on the individual identification information. It is also an object of the present invention to provide a novel manufacturing system and manufacturing method of an ophthalmic lens capable of

Furthermore, according to the present invention, various individual data in the ophthalmic lens can be comprehensively managed using a computer, and even if an accident occurs in the computer, work at each process site is also possible. Another object of the present invention is to provide a new manufacturing system and method for manufacturing an ophthalmic lens that will avoid adverse effects as much as possible.

Means to solve the problem

The feature of the present invention relating to the “manufacturing line for ophthalmic lenses” made to solve the problematic issues is (a) a system for continuously manufacturing a large number of ophthalmic lenses. (B) a container provided with a container for separately storing the ophthalmic lens in an intermediately processed or processed state, (c) a transfer means for transferring the container to a plurality of process areas, (d) Individual information storage means provided in the container for storing information as an electric signal so as to be written in a readable manner; (e) provided at a plurality of locations on the transport path of the container by the transport means; Love A reader / writer device for writing and reading information to the information storage means, and (f) identification information for managing each of the large number of ophthalmic lenses separately as an electric signal and capable of writing and reading Z readable Identification information storage means, processing instruction information storage means for storing the processing instruction information for each ophthalmic lens in association with the identification information as an electric signal and storing the information in a readable manner as the electric signal, A processing completion information storage unit for storing processing completion information for each ophthalmic lens as an electrical signal and storing the processing readability so as to be readable, and integrated information storage unit provided separately from the individual information storage unit; (G) accessing the integrated information storage unit, the identification information, the processing instruction information and the processing completion information to the identification information storage unit, the processing instruction information storage unit, and the processing completion information storage unit; Write Z Read And a management computer that accesses the reader / writer device and writes the identification information, the processing instruction information, and the processing completion information to the individual information storage unit. In the manufacturing system.

[0020] In the ophthalmic lens manufacturing system having a structure according to the present invention, the container, which is sequentially transported to a plurality of regions to be processed or inspected in the ophthalmic lens, is accommodated in the container portion. The ophthalmic lens which has been inserted can be identified separately by the identification information of the individual information storage means attached to the container. Moreover, in such individual information storage means, processing instruction information such as design values and standard values described in the conventional instruction manual is stored as corresponding individual data in the ophthalmic lens housed in the container. It is.

[0021] Therefore, the reader / writer device installed at an appropriate location, such as the area of each process for processing and inspection of the ophthalmic lens, requires design values and standard values of the ophthalmic lens. It can sometimes be obtained quickly. This eliminates the need for the complicated work of organizing and managing conventional paper-sized instructions, and eliminates the possibility of misinterpretation with other ophthalmic lens values or loss of instructions.

Furthermore, in the area of each process or inspection process requiring no data transmission and reception through a computer network, it is possible to directly obtain design values and standard values from individual information storage means attached to the container. it can. Therefore, the amount of data transmission and reception in the computer network is reduced, and the occurrence of an accident on the computer system is avoided as much as possible. In other words, the present process of processing and In the field, it will be possible to continue the work based on the information obtained directly from the individual information storage means attached to the container.

In addition, the individual information storage means attached to each container stores, as information on the results of processing and inspection performed in each process, for example, processing completion information including the presence or absence of the execution of each processing and inspection. Be done. This processing completion information is directly provided by the reader / writer device at each processing site where processing and inspection are performed.

Therefore, even if communication with the management computer can not be performed due to the occurrence of an accident in the computer system or its network, the influence on the site can be avoided more advantageously. That is, information such as completion or completion of each individual processing or inspection on the ophthalmic lens can be stored in the individual information storage means until the accident is resolved. Therefore, after the accident has been eliminated, the management computer confirms the processing completion information stored in the individual information storage means, and it is possible to cope with the processing and inspection in the field as much as possible without interruption. It becomes.

Further, in the ophthalmic lens manufacturing system of the present invention, various information stored in each individual information storage means is also stored in the general information storage means. Therefore, even if any problem is found later, it is possible to efficiently identify the ophthalmic lens to be the subject of the problem based on the information stored in the integrated information storage means. Then, it is possible to accurately select only a specific ophthalmic lens in correspondence with the information of the individual information storage means attached to the container, and to perform disposal such as reprocessing, reinspection or discarding efficiently and accurately. It will be

In the ophthalmic lens manufacturing system according to the present invention, the container for housing the ophthalmic lens is a container for separately storing the ophthalmic lenses, that is, the individual ophthalmic lenses can be distinguished from each other. It is good if it is. Specifically, for example, in addition to a stand-alone type having only one storage location for storing one ophthalmic lens, and a pallet type having a plurality of storage locations for separately storing a plurality of ophthalmic lenses. It may be.

[0027] In addition, in the production of an ophthalmic lens, such containers do not need to use a single unit in all processes when providing the ophthalmic lens to a plurality of processing steps and inspection steps. In the middle of the process, transfer to another container, or return to the original container as needed. It is good. Alternatively, when it is necessary to identify and manage the ophthalmic lens individually in only a few specific steps, the container is adopted and managed separately in only the caustic step, and in the other steps. It is also possible to manage ophthalmic lenses on a lot basis.

In the ophthalmic lens manufacturing system according to the present invention, as a transfer means for transferring a container, a force by which various conveyers such as a belt conveyer are suitably adopted is not particularly limited. In cases such as carrying out only in a special space such as a clean room, manual transportation may also be employed in combination.

In the ophthalmic lens manufacturing system according to the present invention, as the individual information storage means, one capable of recording and reading out information by an electric signal, more preferably one capable of multiple rewriting is adopted. . In the case of using a pallet type container having a plurality of storage units as described above, the individual information storage means may be any type as long as it can identify each storage unit individually and store data. It is not necessary to physically adopt individual information storage means that correspond to the accommodation units one by one! /.

[0030] Further, as such individual information storage means, specifically, what is called an electronic tag etc. and marketed can be adopted, and in particular, an electric signal for reading and writing can be used as a contact type. It is preferable to use one that can transmit and receive an electric signal in a non-contact manner by electromagnetic waves or the like rather than one having a terminal to which electricity is supplied. Therefore, a wireless IC tag (including a small one called a wireless IC chip) incorporating an antenna for transmitting and receiving data together with the IC chip

Is preferably employed. The shape, size, specific structure, etc. are not limited in any way. The built-in power supply can be equipped with a power supply.

Furthermore, the individual information storage means is attached to the container and transported together with the container to each process area. Specifically, in addition to being unremovable in the state of being buried in the container, it may be detachably attached to the container. If it can not be removed, the reliability is improved, but in the case where the number of times of reuse of the container and the individual information storage means is different, for example, the latter removable structure may be desirable.

Further, in the present invention, as the reader / writer device for accessing stored information to the individual information storage means, besides the fixed type, a portable or small handy set can be adopted. It is In particular, when adopting a wireless IC tag as an individual information storage means, generally, An antenna for communication, antenna means for transmitting and receiving electromagnetic waves carrying information, controller means for modulating and demodulating electromagnetic waves transmitted and received, and information to be transmitted and received are displayed A reader / writer device is adopted which is configured from a system provided with a display means such as a monitor.

In the present invention, as the integrated information storage means, various known electric signal storage media can be adopted. For example, disk, optical disk, magneto-optical disk, or various semiconductor storage media Can be mentioned. In addition, the general information storage means is provided with an arithmetic processing unit independent of itself, and it is possible to use an arithmetic processing unit of a management computer in addition to the one that enables transmission and reception of information by communication means such as a management computer and LAN. Alternatively, they may be built-in type or external type directly connected by IDE, USB, IEEE, SCSI or the like.

In addition, the identification information storage means, the processing instruction information storage means, and the processing completion information storage means in the integrated information storage means need not be physically physically separate but have substantially their respective functions. It is good if you ask.

[0035] In the present invention, the stored information of the identification information storage means includes identification information that can individually identify the container or the ophthalmic lens one by one. This identification information can use, for example, data recorded in a commercially available ID chip or the like. Specifically, data that can be converted to data that can be recognized by humans, such as data that can be read out, such as data that is identified by a combination of a plurality of numbers or symbols, is desirable.

In the present invention, the storage information of the processing instruction information storage means includes design data and Z or standard data which are given as instruction values in advance in processing or inspection. Specifically, the design values or conventional values given by the instruction or the back surface radius of curvature (BC) as the instruction value, refractive power (POWER), lens outer diameter dimension (DIA), central thickness dimension (CT), etc. It contains the concrete value of.

In the present invention, the storage information of the processing completion information storage means includes confirmation data in which an external force is also written as a completion signal of the execution of processing and inspection. Specifically, it includes data stored by a signal such as a specific flag indicating that each calorie process has been completed.

Note that the storage information of the processing instruction information storage means and the processing completion information storage means is It is associated with the storage information of the separate information storage means, whereby each information as described above is stored separately and managed for each individual ophthalmic lens.

Also, in the present invention, the management computer comprises general information storage means and appropriate data transmission / reception means for access to the reader / writer device. The data transmission / reception means may be, for example, a direct connection by parallel, serial, USB, IEEE, etc., but preferably a communication device for transmission / reception of electric signals comprising a wired or wireless LAN mechanism. And a line.

Then, the management computer causes data to be exchanged between the integrated information storage means and the individual information storage means. For example, the data read from one storage means may be stored in the other storage means, each data read from both storage means may be compared, or the data input from the outside may be stored in both storage means. It is desirable to have a configuration that can

By the way, in the ophthalmic lens manufacturing system according to the present invention, the individual information storing means is repeatedly used during continuous manufacturing of the large number of ophthalmic lenses! It is preferable to adopt a configuration in which a use frequency storage means for storing the number of times of repeated use of the individual information storage means is provided in at least one of the individual information storage means and the comprehensive information storage means.

By adopting such usage frequency storage means, when employing an IC chip or the like for which a limited usage frequency is set, it is possible to accurately manage the usage frequency. That is, the actual number of times of use stored in the number of times of use storage means is managed in comparison with the maker equal power of the individual information storage means and the limit value of the number of times of use instructed. Exchange information storage means. As a result, the erroneous operation of the individual information storage means can be prevented, and the management reliability can be further improved. In addition, if the management computer compares and checks whether the actual number of times of use has reached the limited number of times, it becomes possible to efficiently manage the number of times of use.

In the ophthalmic lens manufacturing system according to the present invention, the identification information includes serial number data attached to the ophthalmic lens, and the serial number data is stored in the individual information storage means. The configuration adopted as one of the aforementioned information is preferably adopted. Be

By storing such serial number data in the individual information storage unit, serial number data attached to the package etc. of the manufactured ophthalmic lens is stored in the management computer etc. It can be obtained directly from the personal information storage means that does not go through the host computer. Therefore, the process of printing the serial number data can be performed efficiently and accurately.

Preferably, the serial number data is also stored in the integrated information storage unit as one of the identification information of the ophthalmic lens stored in the individual information storage unit. As a result, even if the identification information of the individual information storage unit used in processing or inspection of the ophthalmic lens is erased after packaging by shipping packaging of the ophthalmic lens, the information is stored in the integrated information storage unit. Based on the data, it is possible to track and manage the packaged ophthalmic lenses.

In the ophthalmic lens manufacturing system according to the present invention, the processing instruction information includes product standard data of the ophthalmic lens, and the product standard data is stored in the individual information storage means. The configuration, which is one of the information to be collected, is preferably adopted.

By storing such product standard data in the individual information storage means, the standard data stored in the individual information storage means is read at the site of the processing or inspection process, and is read. It is possible to carry out processing and inspection with target values. Therefore, it is not necessary to obtain integrated information storage means information at each processing and inspection step, and the load on transmission and reception lines etc. is reduced. Also, even if an accident occurs in a computer system such as a management computer, an integrated information storage unit, or a data transmission / reception system, product specification data stored in the individual information storage unit can be used directly in the field. It will be possible to continue the inspection work.

Further, in the ophthalmic lens manufacturing system according to the present invention, the processing completion information has completed processing in a plurality of processes such as processing, work, measurement, etc. which are predetermined for the aforementioned ophthalmic lens. It is preferable to adopt a configuration in which process completion data indicating each process is included, and the process completion data is one of the information stored in the individual information storage means. Used.

By storing such process completion data in the individual information storage means, for example, even when an accident occurs in the computer system, the process completion data stored in the individual information storage means is stored later. It can be confirmed by the management computer or transmitted to the integrated information storage means for storage. Therefore, even under the occurrence of intense accidents, it is possible to complete processing and inspection steps at the site and complete the following steps as necessary.

Further, in the ophthalmic lens manufacturing system according to the present invention, the time when the processing completion information is subjected to processing in a plurality of processes such as processing, work, measurement, etc. which are predetermined for the ophthalmic lens described above A configuration in which process time data indicating each process is included, and in which the process time data is one of the information stored in the individual information storage means is preferably employed.

By storing such process completion data in the individual information storage means, for example, even if an accident occurs in the computer system, the process time data stored in the individual information storage means is stored later. It can be confirmed by the management computer or transmitted to the integrated information storage means for storage. Therefore, for example, in the case where there is a restriction on the working time to a specific process or a specific process depending on a specific process power, for example, for quality control reasons, even if such an accident occurs, the site Then, the processing and inspection steps can be continued and performed sequentially. Then, after the cancellation of the conflict, it is possible to judge whether the power / non-power satisfying the limit value on the working time is good or bad by using the process completion data stored in the individual information storage means. Therefore, it is possible to avoid the occurrence of a large number of defective products caused by stopping the work in each process when an accident occurs.

Further, in the ophthalmic lens manufacturing system according to the present invention, the processing completion information is a task in which processing in a plurality of steps such as processing, task, measurement, etc. which are predetermined for the ophthalmic lens is performed. It is preferable to adopt a configuration in which the operator data including worker data indicating each person in each process is included and the worker data is one of the information stored in the individual information storage means. By storing such worker data in the individual information storage means, for example, when a specific worker has a suspicion of bacterial contamination or a particular worker has a suspicion of a working error, In some cases, for example, it is possible to efficiently cope with the occurrence of human defects in the ophthalmic lens. Also, since such worker data is stored in the individual information storage means, for example, even if an accident occurs in the computer system, the worker data stored in the individual information storage means is It can be confirmed or transmitted to the integrated information storage means for storage. Therefore, even under intense situations of accidents, it is possible to continue the work of each process such as processing and inspection without abandoning the monitoring function of each worker.

Further, in the ophthalmic lens manufacturing system according to the present invention, when the ophthalmic lens is subjected to processing in each process such as processing, operation, and measurement determined in advance, the ophthalmic lens to be treated is It is preferable to adopt a configuration in which information of a lens is read from the individual information storage means by the reader / writer device and the device used for processing in the process is controlled based on the read information. .

By adopting means for controlling the operation of the processing and inspection apparatus used in the processing and inspection steps in accordance with the individual ophthalmic lens in this manner, the shape and characteristics unique to the ophthalmic lens can be obtained. Processing and inspection can be performed efficiently. Specifically, for example, in the step of inspecting the focal length of the added ophthalmic lens, the confirmation working distance range of the autofocus in the inspection apparatus is determined according to the design value or the like obtained from the individual information storage means. By changing and setting, unnecessary operation time in the inspection apparatus can be omitted. In addition, in the lens surface cutting process, it is also possible to directly numerically control the relative position of the spindle of the cutting device and the cutting tool based on the individual information storage means, the read standard value, etc. It also makes it possible to avoid the occurrence of failures caused by operation errors associated with human intervention.

In the ophthalmic lens manufacturing system according to the present invention, the information stored in the individual information storage unit includes product standard data of the ophthalmic lens, and the container is transported by the transport unit. The processing in the target process area includes an inspection processing step of inspecting the ophthalmic lens, and the processing target in the intensive inspection processing step is to be processed. The product standard data of the ophthalmic lens is read from the individual information storage means by the reader / writer device, and the read product standard data is compared with the inspection result data obtained in the inspection process step. A configuration is suitably employed that includes a quality determination unit that determines whether the ophthalmic lens is good or bad, and a determination result notification unit that reports the determination result of the non-defective item determination unit.

By providing the quality determination means in this manner, it is possible to perform the quality determination of the eye lens based on the inspection result data efficiently and accurately with easier operation, and it is possible to perform artificial operation It is possible to avoid the occurrence of failures caused by work errors associated with the intervention.

The product specification data may be a design value of a product, or may be a specification value of a product generally equal to the design value. In the case of the standard value, for example, as in the case of dioptric power (diopter value), in general, it is often set in a plurality of steps at fixed intervals. In that case, as the target product standard data, in addition to a single standard value, several standard values may be adopted, and the non-defective product may be determined by meeting one of the standard values. . That is, even when the detected value 1S is out of the range of one standard value which has been targeted in advance, it may be judged as a non-defective item as being usable if it conforms to another standard which is deviated by one standard.

In addition, the quality determination means may be, for example, an arithmetic processing unit that compares and calculates product standard data and inspection result data as an electric signal, and an output device that outputs the result. The product specification data and the inspection result data may be output, displayed on a monitor or printed, and artificially determined. Further, the determination result notification means is good as long as the determination result is displayed so that the person can recognize it. For example, the product standard data and the inspection result data may be displayed respectively, or the quality determination result may be displayed. In addition, alarm means etc. which notify with light or sound when defect occurs may be used.

Further, in the ophthalmic lens manufacturing system according to the present invention, a plurality of process regions in which the container is transported by the transporting unit is a plurality of the ophthalmic lenses in which the plurality of the processing regions are accommodated. Individually including batch processing steps for simultaneously processing pieces, and information stored respectively in a plurality of the individual information storage means in the batch processing steps collectively in a write Z readable manner. A configuration having information integrated storage means is preferably employed. By adopting such individual information integrated storage means, for example, when processing a large number of ophthalmic lenses at the same time, such as heat sterilization processing, while maintaining the management accuracy for each ophthalmic lens, It becomes possible to carry out the processing efficiently. That is, an eye lens is transferred from a small container having one or a small number of containers to a container having more containers, and the large number of containers are collected in this large container. In batch processing of small-sized containers, small-volume individual information storage means, to large-volume individual information storage means attached to large-sized containers, information of all ophthalmic lenses Migrate This makes it possible to use a small number of controls and a large number of simultaneous controls depending on the process.

For example, in the case where the punching process is finished and provided to the individual treatment process again, the large-volume individual information storage means attached to the large-sized container is attached to the small-sized container. The information of each ophthalmic lens can be transferred to the small volume individual information storage means.

Further, in the ophthalmic lens manufacturing system according to the present invention, a configuration including a printing device for printing a product label using the information stored in the individual information storage means is preferably adopted.

[0064] By adopting such a printing apparatus, various information associated with each one of the ophthalmic lenses by the container is surely printed on the label attached to the product package etc. Can do. Also, since printing information is stored in the individual information storage means, label printing can be performed stably and efficiently without being affected by, for example, an accident of a computer system.

The information to be printed on the product label is not particularly limited, and, for example, measurement data and the like may be adopted as necessary in addition to standard data. In addition, the product label widely includes a display attached or attached to the product package or its package.

In the ophthalmic lens manufacturing system according to the present invention, a plurality of partial management computers and partial information storage means respectively associated with an appropriate number of process regions of the plurality of process regions are provided. The partial management computer is provided in the process area associated with each of the reader / writer device and the partial information storage means. And write and read out the identification information, processing instruction information and processing completion information to the individual information storage means and the partial information storage means, and a plurality of part management computers are provided. A comprehensive management computer for comprehensive management is provided, and the partial management computer and the comprehensive management computer constitute the management computer, and the comprehensive management computer accesses the individual information storage means and the comprehensive information storage means, A configuration in which the identification information, the processing instruction information, and the processing completion information are written to and read from the information storage means is preferably employed.

As described above, by configuring the management computer with the partial management computer and the general management computer and adopting the intermediate storage means, it is possible to easily cope with incidents in the computer system, to suppress the occurrence damage, and to further suppress the occurrence damage. This will make it possible to improve the efficiency and efficiency of system maintenance. For example, even if an accident occurs in the general management computer, the partial management computer can prevent loss of data or transmit and receive necessary information to continue work in each processing and inspection process. It becomes.

Further, the feature of the method for producing an ophthalmic lens according to the present invention is (h) a method for producing an ophthalmic lens for continuously producing a large number of ophthalmic lenses, the method comprising: An individual information storage for storing individual information as an electric signal and storing it in a readable manner as a container for accommodating the ophthalmic lens individually in the intermediate processing state or the processed state and transporting the ophthalmic lens to a plurality of process areas.

Furthermore, according to the present invention, the management system shown in FIG. 2 constitutes an integrated management system for comprehensively performing production management, inventory management, etc. by simply managing information of each water-containing soft contact lens individually. doing. Specifically, the powerful management system includes, as its hardware, a top-level integrated management computer 12, a medium management computer 14, and a keyboard 16 and a scanner 16 as input / output devices for those management computers. , A monitor 20, a printer 22, etc., and a plurality of work management computers 24.

The general management computer 12, the management computer 14, and the work management computer 24 lower in the system configuration than them are all connected directly to the CPU, ROM, RAM, IDE, etc. A computer equipped with a computer is adopted. Especially true In the embodiment, a data server 25 connected by LAN to these computers 12, 14, 24 is provided. The data server 25 is accessible from the general management computer 12, the management computer 14 and the work management computer 24, and has a hard disk as a general information storage means.

Also, the work management computer 24 is installed at a necessary place among the many work areas shown in FIG. 1 described above. In some work areas, a plurality of work management computers 24 are installed for data storage and management and the like. In addition, in these work areas (a plurality of equipment areas 26 and inspection areas 28 shown in FIG. 2 and corresponding to appropriate process areas P1 to P22 in FIG. 1), as necessary, A reader 'writer device 30 is installed.

The reader / writer device 30 is configured to read and write information (read / write) in a noncontact manner using electromagnetic waves with respect to a predetermined data carry 32 as individual information storage means. It has become Each reader / writer device 30 is connected to a network system including the computers 12, 14 and 24 described above. Specifically, such a reader / writer device 30 is used in an RFID (Radio Frequency Identification) system, in which an IC chip or an ID chip, an IC tag or an ID tag is used as the data carrier 32.

You will be able to check!

Hereinafter, based on FIGS. 1 to 4, a hydrous soft contact lens (hereinafter referred to as “contact The manufacturing process of “1” and “1” will be described sequentially.

Note that the computer network system of the present embodiment is configured with an integrated management system that performs production management, inventory management, and the like by operating the plurality of computers 12, 14 and the like as described above with the integrated management software. doing. Specifically, the powerful comprehensive management system is also adopted in the production management of pharmaceuticals and the like, and it is possible to use, for example, Hit FamMS (registered trademark) of Hitachi, Ltd. and Fur of Yamatake Co., Ltd. It is built using well-known commercial integrated management software such as Pharmamanage (registered trademark).

And, in the present embodiment relating to a contact lens manufacturing system, it is realized by utilizing a part of the functions of these commercially available integrated management software. That is, these general management softwares have functions to individually identify products with identification codes and to realize information management and information storage for each of the individual products. Therefore, the details of the specific software for realizing information management and information storage for each product in the computer system will not be described here.

[0091] When starting the manufacturing process of the contact lens shown in FIG. 3, first, a rod-like force-formed material for obtaining a contact lens is prepared for manufacturing. This rod-like hard coating material is a known material obtained by polymerizing a crosslinking agent or a monomer suitable for a raw material such as PHEM A (polyhydroxy ethyl methacrylate) or PVP (polyvinyl pyrrolidone). is there.

In general, a large number of rod-shaped workpieces are produced under the same composition and the same molding conditions. The production unit is divided into lots and managed, and it is carried into the area for receiving lens material at the production site of contact lenses by the race cutting method: P1 (see Figure 1).

[0093] The rod-shaped processed material thus delivered is conveyed to the area of the humidity control process: P2 and subjected to the humidity control storage process: S 1 (see FIG. 3). This humidity control storage step: S1 is to equalize the moisture content of all the rod-like coated materials used in the manufacture of contact lenses. Specifically, for example, the rod-shaped workpiece delivered in a sealed package state is opened, and the rod-shaped workpiece is stored for a predetermined time set in advance under an atmosphere in which temperature and humidity are controlled. Adjust the moisture content. This moisture content also differs depending on the contact lens material, generally less than 10% It is set to the dry state in the appropriate numerical range of.

Then, in the subsequent time judgment step: S2 the humidity control storage step of the rod-shaped workpiece: the time required for the humidity control processing time in S1 to reach the required time set in advance, it is necessary time The one that has passed is sent to the next step.

On the other hand, humidity control storage step: Before treatment with S1 or after humidity control storage step: After the treatment with S1, an appropriate number of rod-shaped workpieces are extracted and placed in another measurement area (not shown). Transferred and subjected to physical property measurement process: S3. And in this physical property measuring step: S3, in the humidity-controlled storage step: S1, the rod-shaped processing is performed under a dry condition of substantially the same humidity and temperature as the rod-shaped processed material to be subjected to processing described later While the material is in a swollen state, various physical property values are measured. This physical property value is used for the quality determination, which will be described later, and more specifically, the refractive index in the dry state: C1, and the linear swelling ratio when the dry state power is also in the swollen state: D, the swollen state Refractive index at: C2 etc.

The swollen state refers to a state in which the rod-shaped material is completely swollen by being hydrated to the equilibrium state (saturated state) in treated water in which the osmotic pressure is adjusted. The linear swelling ratio represents a one-dimensional elongation when the rod-processed material in a dry state swells due to water absorption.

Meanwhile, the details of the target contact lens are examined, and the standard value as a design value is determined. In the present embodiment, this standard value is set as a value in a swollen state of the contact lens in consideration of the ISO standard and the like regarding the contact lens. And, at the time of cutting processing of the front and the back which are done during the manufacturing process of the following contact lens

The target shape of processing is set based on the standard value determined here. In addition, even in the case of inspections and quality determinations appropriately performed during the manufacturing process, it is basically determined whether or not the force conforms to these standard values.

At that time, it is desirable to consider an error that occurs in processing or measurement due to processing error, aberration, measurement conditions, and the like. Therefore, in the present embodiment, a correction value for processing in consideration of such an error is also determined in advance in accordance with the shape, material, processing conditions, apparatus, etc. of the contact lens to be targeted. Predetermined together with the value Specifically, as the correction data: B, for example, the value of refractive power: P (Diopter) or the value of the apex curvature of the front surface of the aspheric lens is approximately corrected by least squares approximation or the like. It is effective to adopt correction parameters and parameters for conversion correction to ISO specifications (contact measurement) when the lens center thickness is measured without contact.

After the physical property measurement of the lens material (rod-shaped molding material) and the determination of the standard value of the contact lens to be made in this way, the rod-shaped processed material conditioned to a predetermined dry condition is obtained. For

V. Let's focus on the manufacture of contact lenses.

[0101] For this purpose, first, the conditioned rod-shaped force forming material is transported to the area of the lens blanks forming step: P3, and the rod-shaped material is cut at an appropriate axial thickness to obtain one rod. Cut out several lens blanks from the rod-shaped workpiece of Each of these lens blanks is an intermediately processed product of a contact lens, and is made into a single contact lens as a product by cutting or the like described later.

The step of obtaining lens blanks from such a rod-like material is performed in advance at a place different from the contact lens manufacturing step, and the obtained lens blanks are used as a contact lens manufacturing place. It may be carried in. In that case, in the area of the above-mentioned receiving process shown in FIG. 1: In P1, lens blanks are received as lens material. This lens blank is carried in a sealed package, and in the area of the next humidity control step: after being sealed, the lens humidity is adjusted and adjusted to a predetermined moisture content, and then contact is made in the same manner as described above. It will be provided to the manufacture of the lens. In addition, when a lens blank hermetically sealed package such as a force stick is carried into a manufacturing place of a contact lens, an appropriate number of lens blanks are extracted and inspected, and the various physical properties described above are measured, and various types of Correction data: B is acquired.

On the other hand, in a process area different from the process of preparing the lens blank as described above: In P4, a container for accommodating and transporting the contact lens in the intermediate processing state is prepared. This container may be any container as long as it can stably accommodate the contact lens when being transported by the transport means 10. In particular, in the present embodiment, since the contact lens is transported in a state of being immersed in the treatment water in a specific treatment process as described later, for example, as shown in FIG. Provided as a separate container 38. This individual container 38 is Only one contact lens 40 in the intermediate processing state or in the processed state is accommodated.

Further, in each individual container 38, the aforementioned data carrier 32 is fixed in a buried state to the thick bottom wall portion. The data carry 32 stores an ID code that can individually identify a large number of data carries 32. If the ID code is not stored in advance, write it. Furthermore, the data carry 32 has a rewritable information storage area, which can be stored in the ID code storage area.

Data writing step: In S4, data required for cutting and inspection of the contact lens are written in the rewritable information storage area in the data carry 32. In the present embodiment, as the data to be written, the standard value of the contact lens previously determined as described above: A (BC, P, DIA, CT), the correction data: B, and the material property measured in advance. Values: Includes C, D. The data written to the data carry 32 is also transmitted to the general management computer 12 and stored in the data server 25.

The data server 25 has its information recording medium functioned as three storage means: identification information storage means, processing instruction information storage means, and processing completion information storage means. Then, in the functional part as the identification information storage means, the ID code attached to all the data carry 32 used is stored as identification information, and the value of the number of times of use in the data carry 32 is also stored. . The number of times of use is incremented by one each time the data carry 32 is repeatedly used, and is managed by the general management computer 12 so as to be discarded etc. before the number of rewrites of the data carry 32 exceeds the allowable number.

Further, in a function part as processing instruction information storage means in the information recording medium of the data server 25, information necessary for processing execution of cutting and inspection is stored as processing instruction information. In the present embodiment, material physical property values are stored in addition to the target contact lens standard value and correction data as the processing instruction information to be applied.

Furthermore, the function part as the processing completion information storage means in the information recording medium of the data server 25 was completed for each process such as cutting and inspection performed during the manufacturing process of the contact lens. Information as to whether or not power is stored as processing completion information Ru. Although this process completion information may be manually input as a process completion signal, in the present embodiment, the areas to be subjected to the process and inspection in the manufacturing process of the contact lens are respectively: P 1 to 22. Using the recognition information of the data carry 32 by the installed reader / writer device 30, the passage flag is automatically issued as a process completion signal and stored. The processing completion signal is also written to the rewritable information storage area in each data carry 32.

Furthermore, the function part as the processing completion information storage means in the information recording medium of the data server 25 was in charge of the processing for each process such as cutting and inspection performed during the manufacturing process of the contact lens. The worker ID (name, etc.) is also stored so that the worker can be identified. This worker information is, for example, a region where processing and inspection are carried out in the manufacturing process of the contact lens every time the worker is replaced with ID card data given to each worker: Readers respectively installed in Pl to 22 'The data is read by the writer device 30 and stored in the data server 25. The worker information is also written to the rewritable information storage area in each data carry 32.

The data respectively stored in the processing instruction information storage means and the processing completion information storage means is associated with the ID code of each data carry 32 stored in the identification information storage means. Thereby, the data server 25 distinguishes the individual contact lenses 40 transported in the individual containers 38 to which the data carriers 32 are mounted, and the processing instruction information and the processing completion information are individually classified for each contact lens 40. And the general management computer 12 etc. can access and write, read, and rewrite information as needed.

Thereafter, the intermediate product (lens blanks) 40a of the contact lens and the individual container 38 are transferred to the area of the lens accommodation step: P5, and are shown by phantom lines in FIG. As such, the intermediate processed product 40a is accommodated in the individual container 38.

Then, the individual container 38 containing the intermediate processed product 40a is transported to the cutting region of the lens rear surface: P6, and in this region: P6, the rear surface covering process: S5 is performed. As a cutting device, a conventionally known numerical control cutting device as disclosed in, for example, Japanese Patent Application Laid-Open No. 08-252755 can be used. Also, in the case of such back surface processing, the standard value of the base curve is read from the data carry 32 by the reader / writer device 30 installed in the cutting processing area: P6, and the back surface curvature is determined based on that value. It carries out by carrying out operation control of the cutting device according to such a back surface curvature. In addition, since the back surface curvature is the value in the swelling state of the standard curve value (BC) of the base curve, the back surface at the time of cutting of the intermediate workpiece 40a in the dry state in consideration of the linear expansion rate (D). Find curvature. The obtained back surface curvature for cutting is transmitted from the work management computer 24 to the general management computer 12 and also stored in the data server 25.

The rear surface processing step: This is a rear surface processed lens having a lens rear surface 42 cut at a predetermined curvature as shown in FIG. 6 by covering the intermediate processed product 40a in S5. An intermediate workpiece 40b is obtained. The obtained intermediate processed product 40b is returned to the individual container 38, and conveyed to the area of the step of curvature measurement and quality determination of the lens rear surface: P7.

In this area: P7, first, with respect to the intermediate product 40b, the back surface curvature measurement step: S6 is performed in the dry state. The measurement of the back surface curvature is performed by measuring the curvature: E of the optical part at the lens back surface 42 of the intermediate product 40 b using a known optical measuring device called a contact lens analyzer etc. I can do it. The measuring apparatus of this type is a known one disclosed in, for example, Japanese Patent Application Laid-Open Nos. 04-331345 and 07-174664, and Japanese Patent Application Laid-Open No. 09-229819.

Incidentally, in the case of measurement of the back surface curvature: E, read the standard curve value (BC) of the base curve from the data carry 32 and also obtain the approximate value of the back surface curvature: E, the value thereof. It is desirable to operate the optical measuring device to search for values in the vicinity of. As a result, the measuring width of the optical measuring device can be initially subjected to force reduction and measurement operation can be performed, and the measurement operation can be simplified and the measurement time can be shortened.

The value of the back surface curvature: E thus measured is written in the data carry 32 and transmitted from the work management computer 24 to the general management computer 12 and also stored in the data server 25.

Also, using the value of the back surface curvature: E thus determined, the back surface quality determination step: The quality determination is performed in S7.

This pass / fail judgment compares the measured value of back surface curvature: E with the standard value read from data carry 32: the value of BC, and judges whether or not the standard value: BC is within the allowable range. Do. Here, since the standard value read out from the data carry 32: BC is indicated by the value of the swelling state, the back surface curvature of the intermediate processed product 40b measured in the dry state: the linear swelling ratio for comparison with E. : Adopt the converted value calculated using D.

[0119] Forced rear surface quality determination step: When it is determined that a defect is required in S7, it is determined whether or not the occurrence of the need for an alarm is large, if the occurrence error is considered to be a facility defect or the like, At the same time as giving an alarm, in the disposal process: S8 discard the intermediate workpiece 40b as a defective product. Disposal of the intermediate product 40b is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual container 38 used for transporting the intermediate product 40b is collected and subjected to reuse.

[0120] In addition, the area of the process of curvature measurement and pass / fail judgment: The alert monitoring process: whether or not the alarm is repeatedly emitted for the plurality of intermediate workpieces 40b continuously transported to P7. To monitor. If an alert has been issued continuously for a predetermined number of intermediate products 40b, a warning will be issued or the facility will be shut down, and a facility check will be requested.

Rear surface quality determination step: If it is confirmed in S7 that the rear surface processing is performed within the allowable error range, the intermediate workpiece 40b is transported to the area of the jig bonding step: P8. Then, in the jig bonding step: S10, the lens rear surface 42 of the intermediate product 40b is bonded to a predetermined processing jig 44 (see FIG. 7) with an appropriate adhesive 46. Thereafter, the intermediate product 40b bonded with the processing jig 44 is returned to the individual container 38, and is conveyed to the area of cutting on the front surface of the lens: P9.

Then, in the front surface processing step: In S11, the intermediate processing product 40b is subjected to cutting processing of the lens front surface 48 and the edge portion 50, and as shown in FIG. A contact lens 40 with characteristics is obtained. A method for cutting a contact lens using such a processing jig 44 is known as described in, for example, Japanese Patent Application Laid-Open No. 07-195556.

Note that, for example, the value of the front surface curvature obtained by calculation can be applied to the front surface movement. That is, the curvature set on the front surface is obtained using values such as base curve: BC (back surface radius of curvature) and power: P (refractive power) described in the processing instruction. Then, by controlling the operation of the cutting device according to the obtained front surface curvature, the front surface cutting You can do In addition, as the cutting device, the same one as the above-mentioned rear surface processing can be adopted. Also, the value of the front curvature obtained by the calculation is stored in the data server 25 through the computer network.

Subsequently, the obtained contact lens 40 is returned to the individual container 38, and is transported to the area of the process of measuring the curvature of the front surface of the lens and judging the quality: P10.

In this region: In P10, first, the curvature of the lens front surface 48 machined is measured. At that time, similar to the curvature measurement of the lens rear surface 42 described above, the force using a known optical measuring device is used to measure the average curvature of a predetermined irradiation area of the measurement light in the lens. From the fact, before the measurement, the propriety of the use of the device is judged. That is, in the measurement range discrimination step: S12, the contact lens 40 is considered in consideration of the specifications (Z) of the measuring instrument used and the specifications (A, B, C, D) of the contact lens 40 to be measured. Determine whether it is appropriate to use a measuring instrument.

This judgment is made, for example, with a predetermined curvature as an optical part in the field diameter specified by the following equation under individual specific measurement conditions: φ Da and the contact lens 40 to be measured This can be done by comparing the optical diameter of the lens front surface 48, the entrance pupil: () Db.

Diameter of view: φ ϋ & = 2 前面 Lens front surface curvature of 48: E X numerical aperture: NA

That is, if the relationship between the force field diameter: φ Da and the entrance pupil: φ Db is φ Da φ φ Db, it is possible to measure the curvature of the front surface 48 of the contact lens 40. On the other hand, if> Da> φDb, the front surface 48 of the contact lens 40 including the peripheral portion that is not the optical portion becomes a measurement target. Therefore, in this case, the measurement is performed by another method (measurement method in a swollen state described later), assuming that the visual field diameter is out of the measurement range. Therefore, in the case of> a a> <i) Db, it is added to the below-mentioned mark addition step (S17) which does not go through the following steps of measurement of front surface curvature under dry condition and quality judgment. In the subsequent standard inspection process (S26), it is processed by inspection in a swollen state according to the conventional method.

Then, when it is confirmed that φ Da φ φ Db, the front surface curvature measuring step: S13 is performed. The measurement of the front surface curvature can be performed using a known optical measurement device called a contact lens analyzer or the like, as in the measurement of the back surface curvature described above. This front song Measured value of rate: F is written to the data carry 32 and the work management computer 24 is also sent to the general management computer 12 and also stored in the data server 25. In addition, since the measured values of the front surface curvature by the contact lens analyzer are averaged in the irradiation range of the measurement light beam, it is desirable to appropriately correct the measured values in the case of an aspheric lens or the like.

Further, using the value of the front surface curvature: F thus determined, the front / rear quality determination step: the quality determination is performed in S14. This judgment is made by reading out the setting value of the front surface curvature calculated in the front surface processing step: S11 from the data carrier 32, comparing it with the measured value of the front surface curvature: F, and judging whether it is within the allowable range. .

Forced front surface quality determination step: If it is determined that a defect is required in S14, it is determined whether there is a need for an alarm, and if the occurrence error is very large enough to be considered to be an equipment defect or the like, Generate an alarm and discard process: Dispose the contact lens 40 as a defective product at S15. The disposal of the contact lens 40 is sent to the general management computer 12 of the work management computer 24 and recorded in the data server 25. The individual containers 38 used to transport the contact lens 40 are collected and reused.

In addition, with regard to the plurality of contact lenses 40 sent continuously, it is monitored in the alarm monitoring step: S16 whether or not the alarm is repeatedly emitted. If an alert has been issued to a predetermined number or more of contact lenses 40 in a row, a warning will be issued or the equipment will be shut down to request an equipment check.

Front Quality Judgment Step: If it is confirmed in S14 that front surface processing is performed within the allowable error range, the contact lens 40 is transported to the area of the marking process step: P11. Then, in step S17, a peripheral portion of the contact lens 40 is marked with a product mark using a known laser device or the like. The specific content of the product mark to be attached is set with reference to the standard value read out from the data carrier. The irradiation intensity, time, etc. of the laser by the laser device are set according to the material etc. of the contact lens 40, and this setting value is also stored in the data server 25 through the computer network. It can be confirmed from

[0133] The contact lens 40 subjected to cutting and marking as described above is separated into individual containers 3 Return to 8 and transfer to the area of the jig detachment step: PI 2. Then, in the jig removal step: S18, the contact lens 40 is separated from the casing 44 to form a single body. In addition, the detachment of the contact lens 40 by the Caro processing jig 44 force, etc. can be performed by a known method as described in, for example, JP-A-09-90290, that is, by deforming the processing jig 44 made of synthetic resin. It can be done easily. Alternatively, the contact lens 40 can be detached from the casing 44 by immersing in the liquid to swell the contact lens 40.

Thereafter, the single contact lens 40 is returned to the individual container 38, transported to the area of the lens thickness measurement and quality determination step: P13, and subjected to the thickness measurement step: S19. Thickness Measurement Step: In S19, the lens thickness on the central axis of the contact lens 40 is measured in the dry state. In the present embodiment, the force measurement is performed using an optical measuring instrument such as, for example, a laser focus displacement gauge. Therefore, regarding the measurement conditions, the correction value obtained by performing correction and converting it into the swelling state is in order to match with the standard value that adopts the value measured using the lightmatic for the contact lens in the swelling state. Lens thickness measurement value: adopted as G. Forced lens thickness measurements: G is written to the data carry 32 and also stored on the data server 25 through the computer network.

Subsequently, in step S20, the value of lens thickness measurement value: G is used to determine whether processing is good or bad. In this determination, the lens thickness conversion measurement value: G is compared with the data carry 32 force read out standard value: CT to determine whether or not the force is within the allowable range. This lens thickness pass / fail judgment step: If it is judged as a defect in S20, the contact lens 40 is discarded as a defect in step S21. The disposal of the contact lens 40 is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual containers 38 used to transport the contact lens 40 are collected and reused.

Thickness Good or Poor Determination Step: For the contact lens 40 that has been determined as a good product in S20, a power good or bad determination step: S22 is performed. In this pass / fail determination, the tolerance (refractive power) of the obtained contact lens 40 is compared with the value of the standard value P read from the data carry 32 to determine whether or not the force is within the allowable range.

Here, the standard value read out from the data carry 32: P indicates the value of the swelling state Since the power of the contact lens 40 in the dry state is determined to be good or bad, the calculated value is adopted as the power of the contact lens 40. This calculated value can be calculated using a known optical equation obtained by modifying the Gauss equation in power calculation process using values such as the shape and refractive index of the contact lens 40 actually measured in the above-described steps. come.

Then, if it is determined that the power is good or bad in step S22, the contact lens 40 is discarded as a bad product in step S24. The disposal of the contact lens 40 is sent from the work management computer 24 to the general management computer 12 and recorded in the data server 25. The individual containers 38 used to transport the contact lens 40 are collected and reused.

Thickness pass / fail judgment step: The contact lens 40 judged to be good at S20 is returned to the individual container 38, and conveyed to the area of the lens swelling step: P14. Then, in the immersing step: S25, the contact lens 40 is immersed in a predetermined treatment liquid for a predetermined time to completely swell the contact lens 40. The treatment liquid to be used is prepared in advance by adjusting the osmotic pressure and temperature according to the material of the contact lens 40 and the like. In addition, processing conditions such as temperature and immersion time at the time of this swelling processing are recorded on the data server 25 through a computer network and can be confirmed later.

The completely swollen contact lens 40 is returned to the individual container 38, and is transported to the area of the inspection step of the lens standard: P15, which is the next step area. Here, in order to maintain the swelling state of the contact lens 40, a storage solution 52 is injected into the housing portion 36 of the individual container 38 as shown in FIG. 8 and the contact lens 40 is immersed therein. To accommodate.

Then, in the standard inspection step: In S26, the required values of the shape and optical characteristics of the contact lens 40 in the swollen state are measured, and the measured values are compared with the standard values read from the data carrier 32 Determine

In the present embodiment, the measurement of the back surface curvature, the front surface curvature, and the lens thickness in the dry state carried out during the cutting process as described above, and the base curve and bending using those measured values The rejection of the defective product is almost achieved by the quality judgment of the lens thickness and the like. Therefore, the standard inspection process: The standard inspection of the contact lens 40 in the swollen state in S26 is not necessarily all There is no need to do a few. Specifically, for example, the measurement range determination step before the front surface curvature measurement

For the contact lens 40 determined in S12 that the measurement range in the dry state is not appropriate, the measurement of the front surface radius of curvature and the refractive power in the swollen state and the quality determination thereof are performed.

Standard inspection process: The measurement result in S 26 is transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25, and is also written in the data carry 32 as needed. In addition, when it is determined that the standard inspection process: S26 is a defect, in step S27, the contact lens 40 is discarded as a defect. When the contact lens 40 is disposed of, it is also recorded in the data server 25 as information. The individual containers 38 used to transport the discarded contact lenses 40 are collected and reused.

Standard inspection process: The contact lens 40 that has passed through S26 is returned to the individual container 38 and transported to the area of the puff cleaning process: P16. Then, in the puff cleaning step: In S28, the swollen contact lens 40 is subjected to puff cleaning to remove cutting flaws and the like. The conditions of the puff cleaning, such as the cleaning agent used and the puff cleaning time, are transmitted from the work management computer 24 to the general management computer 12 and recorded in the data server 25.

Puff Cleaning Step: The contact lens 40 that has passed through S28 is returned to the individual container 38 and conveyed to the area of the surface inspection step: P17. In the surface inspection step: S29, the lens surface condition of the contact lens 40 in a swollen state is inspected using a magnifying glass, an optical camera or the like, and inspected for the presence or absence of damage such as scratches and chips. The inspection conditions, for example, the water flow speed (pump speed) and the illumination intensity in the case of inspection in the state of immersion in water, are transmitted from the work management computer 24 to the general management computer 12, and the data server 25 Record on

In the surface inspection step: when it is determined that the surface is defective in S29, the contact lens 40 is discarded as a defect in step S27. Even when the contact lens 40 is disposed of, it is recorded in the data server 25 as information. Used to transport the discarded contact lens 40, the individual container 38 is recovered and reused.

Surface Inspection Process: Region of Storage Process in Packaging Case: The contact lens 40 that has passed through S29 is stored in a separately prepared packaging case in P18. Storage Process: S30 is performed. This packaging case is a product case, and is provided with a recess 58 for storing the storage fluid 52 and keeping the contact lens 40 immersed, as shown in, for example, FIGS. The thing is adopted. Preferably, a packaging case 60 made of a synthetic resin material that is transparent to the extent that the presence or absence of the contact lens 40 can be visually recognized from the outside is employed.

Incidentally, the storage of the contact lens 40 in the packaging case 60 is carried out, for example, by taking out the contact lens 40 from the individual container 38 and carrying out a surface inspection in the above-mentioned surface inspection process: S29. It is also possible to do by putting the lens 40 directly into the packaging case 60. In this case, the area of the surface inspection process described above: the area of P17 and the area of the process of storing in the packaging case: P18 are the same area.

After the contact lens 40 is accommodated in the recess 58 of the packaging case 60, a lid sheet (not shown) prepared separately is overlaid on the opening of the recess 58 and covered. The lid sheet is formed of an aluminum foil sheet or the like which does not transmit the contained liquid, and is closely attached to the opening peripheral edge of the recess 58 of the packaging case 60 by heat sealing or the like. As a result, the recess 58 is tightly covered, and the contact lens 40 is immersed in the storage liquid 52.

When the contact lens 40 is to be stored, information such as components (bottle, package, labels, materials, etc.) at the time of storage, an operator, date and time, etc. is collected. These pieces of information are recorded on the data server 25 through the computer network.

Subsequently, the packaging case 60 housing the contact lens 40 is transported to the area of the label printing and sticking process: P19. At this time, the data carrier 32 on which the information of the contact lens 40 is recorded is also transported simultaneously. Specifically, in the present embodiment, as shown in FIGS. 9 and 10, the individual tray 62 is adopted, and the individual tray 62 is subjected to the front-end process together with the packaging case 60 accommodating the contact lens 40. The individual containers 38 used up to this point are also placed and transported simultaneously. In this way, individual correspondence between the contact lens 40 and the individual information of the data carry 32 is maintained.

For example, with the packaging case itself as the container, the data carrier 32 removed from the individual container 38 is attached, or another data carry 32 is attached to the packaging case and the data carrier 32 of the individual container 38 is carried. It is also possible to shift only information from However, It is preferable to simultaneously transport the packaging case 60 and the individual container 38 using the individual tray 62 as described above, since it is possible to reuse the data carrier 32 and eliminate the need for laborious and time-consuming work such as information transfer. .

Region of label printing and sticking process: In P19, a label issuing and sticking step: S31 is performed. The label can be issued by the reader / writer device 30 by reading the information of the data carry 32 and printing the necessary information. The printed label is attached to an appropriate place such as the surface of the lid sheet of the packaging case 60, for example. Here, as the print data of the label, an identification code that can identify the recorded information of the data server 25 for each contact lens 40 in association with the ID code of the data carry 32 is adopted. Specifically, for example, a barcode or a two-dimensional code is attached to a label as an identification code. As a result, even after shipment, it is possible to individually identify the contact lenses 40 and to investigate and consider the recorded information of the data server 25.

[0154] The contact lens 40 is individually packaged in a sealed state, and the packaging case 60 with the product label attached thereto is then sterilized in an autocreping step: S32. In general, the autoclave is carried out batchwise by putting several packaging cases 60 in one processing chamber at the same time. Therefore, in the present embodiment, in order to realize an efficient autoclave, a large container (not shown) capable of simultaneously placing and transporting a large number of packaging cases 60 is separately prepared, and Area: At P20, place a number of labeled packaging cases 60 on this large container.

For example, after placing a label on the packaging case 60, the packaging case 60 may be placed directly on the large container without returning the packaging case 60 to the individual container 38. You can do it by doing it. In this case, the area of the above-mentioned label issuing and pasting step: The area of the step P19 and the area of the transfer step to the large container: the same as P20.

In addition, the large-sized container is equipped with a large-capacity, high-capacity data carrier 64 having a large and robust structure as compared with the individual container 38. Specifically, it can be used commercially as an ID tag etc., which has sufficient heat resistance to the temperature of the autoclave. In this large-capacity data carry 64, all the individual information corresponding to all the packaging cases 60 (contact lenses 40) placed in the large-sized container are data-carried on each individual container 38. Transfer and record from Lee 32 or from data server 25. At that time, for example, the identification code associated with the mounting position of each packaging case 60 in a large container is used as an individual contact lens in the large-volume data carry 64 so that information is not mixed among multiple packaging cases 60. It records in association with the 40 recording information.

Thereafter, the large-sized container on which a large number of packaging cases 60 are placed is transported to the area of the autoclave process: P 21 and the autoclave: S 32 is performed. At this time, the large container on which the packaging case 60 is placed is carried into the autoclave and processed, and after processing, a large number of packaging cases 60 are carried out together with the large container. In this way, it is possible to carry out the autoclave while keeping a large number of packaging cases 60 associated with each individual information not to be confused with each other and to the large-volume data carry 64 and stored.

Autoclave: When applying S32, information such as processing temperature, time and pressure of autoclave is collected. These pieces of information are recorded on the data server 25 through the computer network.

After the processing of the autoclave, all the packaging cases 60 are transported to the area of the final exterior inspection and quality determination process: P22. In the case of forceful transportation, all the packaging cases 60 may be placed on a large container. However, in this embodiment, when it is necessary to reprocess as a result of the quality determination, it is essential to identify and manage the packaging case 60 individually. The large number of packaging cases 60 placed in the containers are transported back to the individual tray 62 again. Large containers used will be reused.

At this time, on each of the individual trays 62, there is placed an individual container 38 provided with a data carrier 32 associated with the packaging case 60 placed thereon. Therefore, unless the individual tray 62 for returning the packaging case 60 is mistaken for the one for the other packaging case 60, the data carry 32 of each individual container 38 may be enough to write the completion information of the autocrepe.

Then, the area of the exterior inspection and quality determination process: Exterior inspection performed in P22: S33 and quality determination: As a result of S34, the packaging case 60 in which the stored contact lens 40 is determined to be non-defective is directly stocked Transport to yard and stock for shipping. Also, the judgment result of the non-defective product is recorded in the data server 25 through the computer network. On the other hand, the exterior inspection: S33 and the quality judgment: As a result of S34, the packaging case 60 judged to be a defective product in which the accommodated contact lens 40 can not be repaired is discarded. Disposal of the contact lens 40 is recorded on the data server 25 through the computer network.

In addition, the exterior inspection: S33 and the quality judgment: As a result of S34, the packaging case 60 judged as the defective product which can be repaired, the accommodated contact lens 40 is returned to the individual tray 62, and is repaired. Return to the area of the Then, perform necessary repair, rework, reprocessing, or reinspection. At that time, as necessary, the packaging case 60 is opened, and the contact lens 40 is taken out for repair. After the repair, all the subsequent processing and inspection steps will be applied to the repaired contact lens 40 again.

After being finally transported to the stock yard as a good product or discarded as a defective product, the individual containers 38 and the individual trays 62 used for the transportation of the packaging case 60 are collected and re-used. We attach to use.

According to the method for manufacturing a contact lens as described above, the condition of the lens blunt is accompanied by the data carrier 32 until the contact lens is finally finished as a good product or discarded as a bad product.領域 Inspection area: P5 ~ 22 will be transported. Then, various data individually associated with each lens blunt are stored in the data carry 32 to be used, and the information can be used in each area: P5 to 22 as needed. In addition, information can be added as needed in each area: P5-22. Furthermore, the information written to the data carry 32 is also synchronized with the information stored in the data server 25.

Therefore, with the reader / writer device 30 installed at an appropriate location, such as the area of each process for processing and inspecting the ophthalmic lens, the design value and the standard value of the ophthalmic lens are required. It is possible to obtain it quickly when you This eliminates the need for the complicated work of organizing and managing conventional paper-sized instructions, and eliminates the possibility of mistaken values for other ophthalmic lenses or lost instructions.

Furthermore, it is possible to directly obtain design values, standard values, etc. from individual information storage means attached to the container in the area of each process or inspection process requiring no data transmission and reception through a computer network. it can. Therefore, data in computer networks In addition to reducing the volume of transmission and reception, even if an accident occurs in the computer system, the impact on the site is avoided as much as possible. That is, in the process of processing and inspecting the ophthalmic lens, the work can be continued based on the information obtained directly from the individual information storage means attached to the container.

[0168] In addition, the individual information storage means attached to each container stores, as information on the results of processing and inspection performed in each process, for example, processing completion information including the presence or absence of execution of each processing and inspection. Be done. This processing completion information is directly applied by the reader / writer apparatus 30 at the site of each process to be processed or inspected.

Therefore, even if an accident occurs on the work management computer 24 or the general management computer 12, information such as the standard values required at the site of each inspection will be stored in the contact lens 40. It can be read and obtained directly from the data carry 32 attached. In addition, a record of processing time and processing completion required at each processing and inspection site and storage of inspection results required at each inspection site are also written in the data carrier attached to contact lens 40. Can be stored and synchronized with the data server 25 after recovery.

Therefore, even if an accident occurs in the work management computer 24 or the general management computer 12, it is possible to minimize the need to stop work on the site such as processing and inspection, which is efficient. Smooth work can be realized stably.

In particular, in the present embodiment, since the inspection after processing is basically performed in the dry state of the contact lens, there are many opportunities to refer to information such as the standard value and the linear swelling ratio at the time of the inspection. By adopting the data carry 32 and the like as described above, necessary information can be obtained quickly and easily, and scheduled production can be stably performed.

Further, in the present embodiment, since the data carrier 32, the individual container 38, the large container, and the like are repeatedly reused, there is also a resource saving effect. Although the stored information of the data carry 32 is rewritten by reuse, in the present embodiment, since various information is stored and accumulated for each contact lens in the data server 25, for example, it will be described later. Even if any problems are found, the ophthalmic lens that is the subject of the It becomes possible to index etc.

Furthermore, in the present embodiment, when changing the instruction, as in the conventional case, the operator makes reference to the instruction consisting of a piece of paper, and the complicated work of adjusting the facilities etc. is not necessary, and switching of the production type is possible. Can be done easily and reliably. Therefore, it is possible to carry out various production activities from high-mix low-volume production to low-mix high-volume production, and it is also easy to alternate between high-mix low-volume production and low-mix high-volume production, which was conventionally difficult. It is possible.

Therefore, by freely switching the production as needed, it is possible to carry out manufacturing in accordance with the lifestyle of the product, and furthermore, it becomes possible to simultaneously cope with multi-kind logistics as well. is there.

Further, the manufacturing process of the contact lens is not limited to the cutting process described above, but may be performed by various methods such as cutting and polishing, single-sided molding, single-sided cutting, double-sided molding and the like. Even if it is, it is possible to apply the above-mentioned system and manufacturing method.
