DESCRIPTION OF EMBODIMENT OR EMBODIMENTS

In FIG. 1, the number 1 designates in general the shrink tunnel of a shrink packager, i.e. of a plant for the shrinking of a shrink film 2 over a pack formation 3, and in at least one possible embodiment, for example, for the formation of packaging units or trading units 4 in which the individual packages that form the pack formation 3 can be held together by the shrunk shrink film 2.
The shrink tunnel 1 forms a tunnel interior 5 which is enclosed from the outside by a tunnel wall. The pack formations 2 which have already been wrapped with the shrink film 2 are moved through the tunnel interior 5 for the shrinking of the shrink film 2 under the action of heat and/or for the formation of the trading unit 4 by means of a conveyor, such as a conveyor belt 6, for example. For this purpose, the tunnel interior 5 is filled with hot air by a heating device 7, so that the temperature of at least 200 degrees Celsius which is necessary and/or desired for the shrinking of the shrink film can be achieved.
At the tunnel entrance 5.1, from which the pack formation 3 provided with the shrink film 2 is moved by means of the conveyor 6 into the tunnel interior 5, and at the tunnel exit 5.2, at which the trading units 4 exit the tunnel interior 5, devices 8 and 9 respectively are provided on the upper side of the tunnel entrance and exit, and by means of which, by a vertical or essentially vertical flow of heated air, an air curtain 8.1 or 9.1 respectively is produced, and in at least one possible embodiment to close off or to enclose the tunnel interior 5 at the tunnel entrance 5.1 and tunnel exit 5.2.
For example, the devices 8 and 9 comprise essentially one or more slotted air discharge openings and corresponding blowers, which can be supplied with hot air from the heater device 7, for example. Outside the tunnel interior, a plurality of cameras 10 and 11 are provided, by means of which the tunnel interior 5 and/or the shrinking process that is taking place there can be monitored through the tunnel entrance 5.1 and the tunnel exit 5.2 respectively, and in one possible embodiment through the respective air curtains 8.1 and 9.1.
In the embodiment of the present application illustrated in FIG. 1, a video camera 1 0 is provided at the tunnel entrance 5.1 and at a sufficient distance from said entrance, and an additional video camera 11 is provided at the tunnel exit 5.2 at a sufficient distance from said exit, for example at a distance of one and half meters to two meters. Heat-resistant electric lamps 12 are used to illuminate the tunnel interior 5, although one of these lamps 12 is shown in FIG. 1 to simplify the illustration.
Through the air curtain 8.1, the video camera 10 monitors or optically records (for display) the first portion of the tunnel interior 5 adjacent to the tunnel entrance 5.1 in the direction of transport A, in which (portion of the tunnel) the decisive steps of the shrinking process take place, namely the sealing of the overlapping segments 2.1 of the shrink film 2 underneath the individual pack formation 3, the inflation of the shrink film over the lateral shrink holes 2.2 that are formed during the wrapping of the individual pack formation 3 and the initiation of the actual shrinking process by heating the individual piece of shrink film, in one possible embodiment on its inner surface that faces the respective pack formation 3. These initial steps of the shrinking process which are monitored or photographed by the video camera 10 already have a decisive effect on the subsequent optical appearance of the trading units 4 and/or the quality of the shrinking process. The step that immediately or substantially immediately follows these first steps of the shrinking process is the final shrinking of the shrink film. The video camera 11, through the air curtain 9.1, photographs the section of the tunnel interior 5 in the direction of transport A preceding the tunnel exit 5.2 and thus also the pack formations 3 or trading units 4 with the shrunk-on shrink film as well as the quality of the individual shrinking process.
The video cameras 10 and 11 are components of a camera or monitoring system which makes possible a variety of applications of the images taken by the cameras 10 and 11, e.g. among other things a display of the images on monitors 14, so that on the basis of these images, among other things, an optimal control of the shrinking process or an optical regulation of the shrink tunnel 1 and/or of the packing line of which this tunnel is a part becomes possible, in one possible embodiment including in the event of an exchange or replacement of the shrink film and/or a change in format, etc.
It is also possible to transmit images supplied by the cameras 10 and 11 that comprise information about errors that occur during the shrinkage process via the camera system 13 and a data transmission system, such as an Internet connection, for example, to a service company that is spatially or geographically remote from the process, such as to the service department of the manufacturer of the shrink tunnel 1, for example, to thereby receive a fast and targeted error analysis that makes it possible to resolve the error that has occurred.
For example, in at least one possible embodiment of the present application, several adjustments may be made to either, or both of, the shrink wrapping machine and the shrink tunnel 1 to alter the wrapped packaging units 4. In one possible embodiment, the speed of the conveyor 6 may be adjusted to a higher speed or a lower speed. This may influence the amount of time the packaging unit 4 spends in the shrink tunnel 1. Also, another adjustment may be made to the temperature of the shrink tunnel 1. The heating device 7 may either increase or decrease its output, and the air curtain-producing devices 8 and 9 may produce air curtains of differing temperatures, depending on the adjustments needed to be
In at least one possible embodiment of the present application, the images recorded by the camera system during the shrinking process are transmitted directly, i.e. without any delay, to the other location, so that the shrinking process can be modified and monitored directly from this remote location. A technician skilled in the art speaks of a data transmission with no delay as an on-line transmission.
It is also possible to store the images or image data supplied by the cameras 10 and 11 for documentation purposes, so that these data can be retrieved if necessary and/or desired.
The above description assumes that two cameras 10 and 11 are provided outside the tunnel interior 5. Of course, there may also be a greater number of cameras and/or it may be sufficient to monitor the first portion of the tunnel interior 5.1 that is downstream of the tunnel entrance 5.1 in the direction of transport A, which is the portion of the tunnel in which the essential steps of the shrinking process occur, with one or with a plurality of cameras.
FIG. 1A shows a schematic side view of a shrink wrapping tunnel similar to that which is seen in FIG. 1. The embodiment seen in FIG. 1A has the additional components including movers or pivotors 50, which are configured to move or pivot the cameras 10 and 11. Also seen in FIG. 1A is a data transmission system 51, which may be configured to relay information or data from the camera system 13 and/or monitor 14 to a data receiver 53. The data transmission system 51 and the data receiver 53 may be connected through the internet 52, which permits the transmission of information or data from the system 51 to the receiver 53.
FIG. 2 shows, in an illustration like FIG. 1, a shrink tunnel 1 a which differs from the shrink tunnel 1 essentially in that at the tunnel entrance 5.1 and at the tunnel exit 5.2, instead of the devices 8 and 9 for the production of the air curtains 8.1 and 9.1 respectively, there is a net curtain or a curtain 15 (at the tunnel entrance 5.1) or 1 5 (at the tunnel exit 5.2) respectively, made of a heat-resistant material. The curtains 15 and 16, with which in turn an enclosure of the tunnel interior 5 is achieved both at the tunnel entrance 5.1 and at the tunnel exit 5.2 respectively, can be realized in one piece or in a plurality of pieces, for example, and in one possible embodiment in the latter case, for example, so that a plurality of curtain elements are next to one another vertically with respect to the direction of transport A of the conveyor belt 6 and/or are provided one after another in the direction of transport A.
For purposes of monitoring, at least one video camera 17 is located in the tunnel interior 5, and in one possible embodiment protected from heat, and can be pivoted or moved so that the details and processes in the tunnel interior 5 can be observed in the greatest possible detail. The camera 17 is in turn a component of the camera system 13, with which the images from the camera 17 are displayed on monitors 14 as described above with reference to the images or image data from the cameras 10 and 11 and/or can be used otherwise. It is therefore also possible to provide additional cameras outside the tunnel interior 5, as illustrated by the broken lines at 11. The video camera 17 is in one possible embodiment provided in a cooler or cooled area of the tunnel interior 5, and in one possible embodiment outside the hot air current that is discharged from nozzles for the shrinking of the shrink film 2.
The conveyor or the conveyor belt 6 can be realized for a single-lane flow of packages or a multiple-lane flow of packages.
FIG. 2A shows a schematic side view of a shrink wrapping tunnel similar to that which is seen in FIG. 2. The embodiment seen in FIG. 2A has the additional components including movers or pivotors 50, which are configured to move or pivot the cameras 11 and 17. Also seen in FIG. 2A is a data transmission system 51, which may be configured to relay information or data from the camera system 13 and/or monitor 14 to a data receiver 53. The data transmission system 51 and the data receiver 53 may be connected through the internet 52, which permits the transmission of information or data from the system 51 to the receiver 53.
FIG. 3 shows schematically the main components of one possible embodiment example of a system for filling containers, specifically, a beverage bottling plant for filling bottles 130 with at least one liquid beverage, in accordance with at least one possible embodiment, in which system or plant could possibly be utilized at least one aspect, or several aspects, of the embodiments disclosed herein.
FIG. 3 shows a rinsing arrangement or rinsing station 101, to which the containers, namely bottles 130, are fed in the direction of travel as indicated by the arrow 131, by a first conveyer arrangement 103, which can be a linear conveyor or a combination of a linear conveyor and a starwheel. Downstream of the rinsing arrangement or rinsing station 101, in the direction of travel as indicated by the arrow 131, the rinsed bottles 130 are transported to a beverage filling machine 105 by a second conveyer arrangement 104 that is formed, for example, by one or more starwheels that introduce bottles 130 into the beverage filling machine 105.
The beverage filling machine 105 shown is of a revolving or rotary design, with a rotor 105′, which revolves around a central, vertical machine axis. The rotor 105′ is designed to receive and hold the bottles 130 for filling at a plurality of filling positions 113 located about the periphery of the rotor 105′. At each of the filling positions 103 is located a filling arrangement 114 having at least one filling device, element, apparatus, or valve. The filling arrangements 114 are designed to introduce a predetermined volume or amount of liquid beverage into the interior of the bottles 130 to a predetermined or desired level.
The filling arrangements 114 receive the liquid beverage material from a toroidal or annular vessel 117, in which a supply of liquid beverage material is stored under pressure by a gas. The toroidal vessel 117 is a component, for example, of the revolving rotor 105′. The toroidal vessel 117 can be connected by means of a rotary coupling or a coupling that permits rotation. The toroidal vessel 117 is also connected to at least one external reservoir or supply of liquid beverage material by a conduit or supply line. In the embodiment shown in FIG. 3, there are two external supply reservoirs 123 and 124, each of which is configured to store either the same liquid beverage product or different products. These reservoirs 123, 124 are connected to the toroidal or annular vessel 117 by corresponding supply lines, conduits, or arrangements 121 and 122. The external supply reservoirs 123, 124 could be in the form of simple storage tanks, or in the form of liquid beverage product mixers, in at least one possible embodiment.
As well as the more typical filling machines having one toroidal vessel, it is possible that in at least one possible embodiment there could be a second toroidal or annular vessel which contains a second product. In this case, each filling arrangement 114 could be connected by separate connections to each of the two toroidal vessels and have two individually-controllable fluid or control valves, so that in each bottle 130, the first product or the second product can be filled by means of an appropriate control of the filling product or fluid valves.
Downstream of the beverage filling machine 105, in the direction of travel of the bottles 130, there can be a beverage bottle closing arrangement or closing station 106 which closes or caps the bottles 130. The beverage bottle closing arrangement or closing station 106 can be connected by a third conveyer arrangement 107 to a beverage bottle labeling arrangement or labeling station 108. The third conveyor arrangement may be formed, for example, by a plurality of starwheels, or may also include a linear conveyor device.
In the illustrated embodiment, the beverage bottle labeling arrangement or labeling station 108 has at least one labeling unit, device, or module, for applying labels to bottles 130. In the embodiment shown, the labeling arrangement 108 is connected by a starwheel conveyer structure to three output conveyer arrangements: a first output conveyer arrangement 109, a second output conveyer arrangement 110, and a third output conveyer arrangement 111, all of which convey filled, closed, and labeled bottles 130 to different locations.
The first output conveyer arrangement 109, in the embodiment shown, is designed to convey bottles 130 that are filled with a first type of liquid beverage supplied by, for example, the supply reservoir 123. The second output conveyer arrangement 110, in the embodiment shown, is designed to convey bottles 130 that are filled with a second type of liquid beverage supplied by, for example, the supply reservoir 124. The third output conveyer arrangement 111, in the embodiment shown, is designed to convey incorrectly labeled bottles 130. To further explain, the labeling arrangement 108 can comprise at least one beverage bottle inspection or monitoring device that inspects or monitors the location of labels on the bottles 130 to determine if the labels have been correctly placed or aligned on the bottles 130. The third output conveyer arrangement 111 removes any bottles 130 which have been incorrectly labeled as determined by the inspecting device.
The beverage bottling plant can be controlled by a central control arrangement 112, which could be, for example, computerized control system that monitors and controls the operation of the various stations and mechanisms of the beverage bottling plant.
FIG. 4 shows a block diagram of several components of a container filling and packaging plant according to the present application. Filled containers may be closed and/or sealed and/or capped at a closing station 50. The closed, filled containers may then be transported to a labeling station 51. The closed, filled containers may then be labeled at the labeling station 51. The labeled, closed, filled containers may then be transferred from the labeling station 51 to a separator or compactor 52. The separator or compactor 52 is configured to separate groups of containers into packs and/or compact the groups of containers into tight groups ready to be wrapped and packaged. The groups of containers may then be transferred to a wrapping machine 53. The wrapping machine 53 is configured to wrap shrink wrap or shrink film around the bundles or groups of containers. The wrapped bundles of containers may then be transferred from the wrapping machine 53 to the shrinking machine or shrink wrapper 1, which is configured to apply heat to the shrink film or shrink wrap and shrink the film that is wrapped around the bundles or groups of containers.
The present application relates to a shrinking tunnel for heat-shrinking film 2 onto package formations 3, having a tunnel interior 5 forming a tunnel entrance 5.1 and a tunnel exit 5.2, wherein the package formations 3 to be provided with heat-shrinking film 2 may be moved through said interior for the purpose of shrinking the heat-shrinking film by the application of heat.
