Description

Disengagement gear
Technical field
The present invention relates to a kind of being used for the disengagement gear of end sheet with one group of mutual stacked parallel sheet separation.
Background technology
As everyone knows, for example exporting in the device of sheet document the document from a stacks of sheets or a well-regulated bundle sheet material, tightly suppress the end sheet of a described stacks of sheets with actuator with regulation friction coefficient, and removable drive by this way, so that end sheet moves away the described document of a described stacks of sheets in its plane the valency document is arranged particularly, for example resemble banknote.As everyone knows, actuator is often not only carried end sheet, but also from a described stacks of sheets, carry one or more adjacent sheet material, and in that respect, same well-known, make actuator that sheet material/described one group of sheet material is transported to disconnector, in described disconnector, many the sheet materials of be not intended to carrying are separated with end sheet and processed, further carry end sheet simultaneously, be used for further handling in addition.Repeat output function from start to finish, leave the disconnector of orderly feeding sheets until the sheet material that detects predetermined quantity.
Yet problem is that the described one phase mutual friction of pricking between the adjacent sheet of sheet material may be significantly different for difference is pricked sheet material.And the phase mutual friction in the described bundle sheet material between the adjacent sheet may be higher, and therefore, the sort of output function of pointing out brings a kind of result more frequently, and promptly one group of extra sheet material is followed end sheet in output function.Even disconnector can separate the sheet material that is not intended to conveying, but the sheet material that its shortcoming is separated device separates is not directly to be sent to predetermined final destination when handling.
If the mutual friction force in a described stacks of sheets between each sheet material is high loathsomely, then may occur in the output function so bigly by the number of sheets of actuator sucking-off from a described stacks of sheets in addition, so that disconnector can not separate the sheet material of extra conveying.Further produce other problems then, these problems mean, whole group sheet material must turn to, these problems also mean, the output function of actuator can not cause any sheet material can both be further to carry through disconnector, and is included in the transmission of sheet material of desired some and among the incoming terminal user.Certainly, this means, all the conveying operations time delay.
Have been noted that in many cases friction force is big mutually between each sheet material in the described stacks of sheets.For example, if sheet material comprises that with described one folded or described one form of pricking directly from the banknote of seal paper money factory or other similarity, the mutual adhewsive action of each sheet material then may be bigger.Especially working as sheets/banknotes is to use some plastic material, when making such as polypropylene, notices, and friction force is big mutually in the described stacks of sheets.Yet, problem is not limited to these situations, and when changing, the friction force between each sheet material in the described stacks of sheets also takes place, because output unit should be conditioned, so that provide and send preferably single sheet material reliably, and disconnector must can solve its task, but also preferably should remove impassabitity disconnector and the one group of sheet material that can not separated device separates.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of disengagement gear, solve described problem whole or in part by this disengagement gear.
Reach described purpose by the present invention.
Technical scheme of the present invention is as follows:
A kind of being used for separated the disengagement gear of end sheet from one group of parallel sheet material, and described one group of parallel sheet material is stacked mutually, and has been transmitted from a stacks of sheets; Described disengagement gear comprises the rotatable roller of pair of parallel, the rotatable roller of described pair of parallel is forming roller folder district between they self, described one group of sheet material moves towards roller folder district in its plane, and its leading edge is parallel with described roller, and first in the described roller is provided in first party and rotates up, so that contact and conveying end sheet on its direction of transfer, it is characterized in that, at place, roller folder district, the enveloping surface of second roller is configured to and can rotates on the hand of rotation opposite with the hand of rotation of the enveloping surface of first roller; The enveloping surface of first roller has the friction coefficient higher than second roller; Mobile device is configured to each roller of mutual bias voltage and each roller is contacted each other; And each roller is each other directed, is used for moving toward each other and away from each other.
The one group of sheet material that has passed out to disconnector from a stacks of sheets in the plane of sheet material should be a low speed in the entrance of disconnector, so that disconnector is operated suitably.Prick the speed of sending end sheet the sheet material because a variety of causes should be high from described one, for example, for single sheet of material can be sent fast, and far away as far as possible, produce fast velocity contrast in order to prick between the end sheet of sheet material and the adjacent sheet described one from a described stacks of sheets.Therefore, the speed of end sheet and the adjacent sheet that may carry must reduce before described one group of sheet material contact separation device.
Accordingly, in a preferred embodiment, suitable disconnector can comprise that two are adjacent to and independently rotary cylinder or roller mutually.The direction rotation that a court in the separator roller is identical with driver roller.Therefore, above-mentioned first separator roller and driver roller can be driven by common drive motor, and intercouple by fixing driving device.Second separator roller preferably is arranged to can be towards the direction rotation opposite with first separator roller.In this regard, one group of sheet material of sending into towards inlet folder district direction between the separator roller is directed, so that end sheet is near first separator roller, therefore and other sheet material in described one group of sheet material is near second separator roller, and the entrance side in the folder district is turned to by described second separator roller thus.Because in fact described one group of sheet material has low velocity in the entrance in disconnector folder district, and other second separator roller has the rotation of indication, the entrance side of sheet material carried by end sheet in disconnector folder district turn to, and can turn to, so that handle in a manner known way.
In order to make disconnector have suitable separation function, require the surface of first roller to have surperficial high friction coefficient, and in addition, require certainly the abutment pressure between the separator roller can be remained in the limited scope, no matter wearing and tearing how than second roller.
In this respect, keep the known structure of adjustable contact force between the roller, although wearing and tearing still need high price.According to further exploitation of the present invention, adopted special mobile device for this reason, compressing in the separator roller by the power that can be easy to control, described mobile device is not subjected to the wearing and tearing of separator roller and the influence of the vary in diameter brought thus basically.According to the present invention, this device can constitute with screw actuator, and described screw actuator comprises magnet winding and movably unshakable in one's determination thus.Those skilled in the art is known, and this screw actuator produces propulsive effort, and the electric current that described propulsive effort applies along with the driving voltage from regulation is along mobile route and great changes have taken place.Yet, by guaranteeing only to utilize solenoidal sub-fraction moving of being used for that separator roller is parallel to each other that may move distance, obtain following state, promptly when constant voltage, the power that is applied by screw actuator becomes with the electric current that applies linear basically.Therefore, one that can drive in the movable separator roller by power leans against on second separator roller, and described power can easily be controlled, and is not subjected to solenoidal effective length to change the influence of (wearing and tearing of separator roller).

The specific embodiment
In Fig. 1, bottom 3, one stacks of sheets 1 are shown are placed on the described bottom 3.A described stacks of sheets 1 comprises the sheet material that piles up mutually, and for example as banknote, described sheet material has identical form usually, and has its extended surface perpendicular to the surface of bottom 3 usually, and the surface of described bottom 3 is parallel to the adjacent face of a described stacks of sheets.A described stacks of sheets 1 moves on its longitudinal direction 4, so that its end sheet 2 ' tightly suppress outlet roller 12, described outlet roller 12 is parallel to bottom 3 and these sheet materials 2, and above bottom 3 a described stacks of sheets 1 of place contact highly, described height is preferably at the first half of sheet material, the i.e. distance in the 0.4-0.9h scope above bottom 3, wherein " h " is the height that piles up, as shown in fig. 1.
A described stacks of sheets 1 is by power N 2 Tightly suppress roller 12, above-mentioned power N 2Cooperate with the friction coefficient of the circumferential surface of roller 12, when roller 12 rotations, produce end sheet 2 ' selected displacing force.
A described stacks of sheets 1 can move with respect to roller 12 with bottom 3.Replacedly, a described stacks of sheets 1 can move along bottom 3.Bottom 3 is arranged in the zone of end sheet 2 ' below at least.In Fig. 1, see disconnector 48 in addition, described disconnector 48 is arranged to when with end sheet 2 ' when upwards sending in its plane, receives and guide tip sheet material 2 ' pass through.If end sheet 2 ' be attended by one or more adjacent sheet 2 in the described stacks of sheets, disconnector then works, make the sheet separation followed and turn to, and they are turned to by steering hardware 49 (not being shown specifically), so that only make single sheet of material, be end sheet 2 ' by disengagement gear, and further be directed to conveyer 60.Sensor 61 can be arranged on beyond the disconnector 48, and detects the banknote that passes through, and for example in order to detect the banknote that may follow terminal banknote, therefore in this case, by steering hardware 62 the described one group of banknote that passes through is turned to.
Disconnector 48 illustrates and comprises two cylinder rollers 11,31, and described two rollers 11,31 are parallel to each other, and compress toward each other.Motor 10 is shown to be driven separator roller 11 and drives outlet roller 12 by another driving device 22 by belt transmission 21 rotations.Second separator roller 31 is driven by motor 30 rotations by driving device 41, and roller 31 can be independent of the rotation of roller 11 and rotate.
When from a described stacks of sheets 1, sending 2 ' time of end sheet, roller 12 at first is rotated towards the first hand of rotation 12A, so that end sheet 2 ' quilt drives towards bottom 3 directions, and experience in that respect in bottom 3 and the elastic heave shape between the contact point between a roller 12 and the described stacks of sheets 1.In that respect, sheet material 2 ' fed distance little so that guarantee sheet material 2 ' protuberance be elasticity, and the sheet material 2 of protuberance ' still be in roller 12 contacts.Secondly, make the rotation of roller 12 reverse, so that roller 12 rotates towards hand of rotation 12B, thus, end sheet 2 ' move up is left the inlet folder district of bottom 3 between separator roller 11,31.If end sheet 2 ' when the disconnector direction is moved, be attended by one or more adjacent sheet at it, as long as described one group of sheet material enters disconnector 48 under low speed, then can be with the described sheet material of following 2 and end sheet 2 ' separate.By making roller 31, make the circumferential surface inverted running of its circumferential surface and roller 11 like this, thereby make sheet material 2/ banknote of following obtain separating effect towards direction rotation.The enveloping surface of roller 11 has coefficientoffriction 1, described coefficientoffriction 1The coefficientoffriction that is higher than roller 31 2, and the opposite hand of rotation of roller 11 and 31 brings a result: the upper limb of the sheet material 2 that the circumferential surface of roller 31 can be followed along longer distance affects obtains the actv. separation process so that compare with the roller 31 that is in idle running.The circumferential velocity of roller 31 is usually less than the circumferential velocity of roller 1.The output function of banknote was carried out in several milliseconds period.
The effective separation of each single sheet of material that enters described one group of sheet material of disconnector 48 means that each single sheet of material enters disconnector under low speed, but roller 12 must under high speed, send sheet material 2 in the described stacks of sheets 1 ', so that output function can be carried out in the period that must lack.Because the CD-ROM drive motor 10 of roller 11 is configured to quicken fast roller 12, then with roller 12 brakings, so this function can be utilized in an advantageous manner by the following fact, promptly during sheet material 2 ' towards disconnector 48 directions is carried, make roller 12 and make thus sheet material 2 ' and the sheet material 2 that may follow ' accelerating action and deceleration effort repeat one or many.Each end sheet 2 ' this continuous accelerating action during, improved end sheet 2 ' with the possibility of separating near sheet material 2.
By roller 12 with in check mode drive end sheet 2 ' mean wherein roller 12 is leaned on end sheet 2 ' abutment force remain in the limited scope.
Thus, suggestion is arranged to roller 12 can move towards the sense of motion 4 of described stacks of sheets 1.The connecting element 70 that is used for the footstalk of roller 12 is supported by supporting member 80 by the spring 71 with known spring performance.The distance that sensor 72 detects between supporting member 80 and the connecting element 70.This represents to rely on the supporting power of footstalk one end apart from S.Under the situation of the two ends of axle corresponding configuration, roller 12 rely on end sheet 2 ' normal force N 2Can keep by push rod 75, described push rod 75 applies and is used for the power that sensor 72 detects preset distance S.
Because the roller in disconnector 48 11,31 slides relative to one another or with respect to the sheet material 2 that is positioned at them, so roller 11,31 is worn, this wearing and tearing mean that roller 11,31 must be able to move towards each other, and compressed by outer force transducer, so that have the predetermined power that adjoins each other N 0(Fig. 3).
Further develop according to the present invention, for this reason, suggestion is arranged in the coaxial plane and can moves towards another roller 11 directions are parallel one in the separator roller, the axle journal of roller 31 is accommodated in the corresponding movable fixed part 33, and described connecting element 33 moves by corresponding linear solenoid 90.
Fig. 4 illustrates, and this commercially available screw actuator 90 has linear course length, and described linear course length is at minimum value L MinWith maxim L MaxBetween.When constant voltage U and continuous current I were added on this screw actuator, this screw actuator produced change power in its trip distance scope.This makes plain solenoid be considered to not too be suitable for the control of power.
We find, to this screw actuator, can select little trip distance scope δ 1, at described little trip distance scope δ 1In, can think that power is linear.In that respect, Fig. 5 illustrates, and under the constant excitation voltage U, is easy to the power that control solenoid 90 produces by feeding current I proportional with it.Like this, the total abutment pressure between the very hopeful maintenance separator roller, and the wearing and tearing of compensating roller 11,31.
Utilize the special advantage of the roller 11,31 that compresses toward each other to be, one group of sheet material 2 ', 2 can not separated device separately and still under the situation in the inlet folder district of disconnector, this situation can detect by for example sensor 61, and this detection causes screw actuator 90 withdrawals, can pass through disconnector so that described one pricks sheet material, the sensor 61 that is positioned at the disconnector downstream detects many sheet materials by disconnector simultaneously, and orders steering hardware 62 that described one group of sheet material is turned in that respect.In addition, alternative is that assembly must stop, and waits for operating personal queueing problem (removing a described bundle sheet material of the entrance side that abuts against disconnector 48).
Use screw actuator 90 to mean that certainly the wearing and tearing of roller 11,31 are smaller, promptly the axial distance length between the roller 11,31 is short, and is more much smaller than solenoidal maximum length of stroke.
Can understand from the structure of Fig. 1, roller 12 can be by motor 10 by driving device 21,22 direct drives, and roller 11 can also use electrical motor 10 direct drives, promptly do not need free gear or other analogue.Same situation is applicable to roller 31, and this roller 31 passes through driving device 41 direct drives by motor 30.
By making roller 31 towards the direction rotation opposite, the sliding motion that in described one group of sheet material that the enveloping surface and the roller folder that is sent sheet material roller 12 to take disconnector to of roller 31 are distinguished, obtains prolonging between the end edge of each sheet material with roller 11.
