Description

  The present invention relates to a paper sheet processing apparatus for processing paper sheets such as securities, and more particularly to a paper sheet processing apparatus provided with a bundling device that controls the length of a band to be bound according to the quality of the paper sheet. .

  A paper sheet processing apparatus for processing paper sheets such as securities takes out paper sheets one by one from a bundle of paper sheets (for example, 1000 sheets) that are input in a batch according to the processing unit. The paper sheet discriminating device discriminates the quality (shape, damage, etc.) of the paper sheet, and it is referred to as a normal ticket (hereinafter referred to as a regular ticket) or a defective ticket (hereinafter referred to as a non-paid ticket). ) And an excluding ticket such as a transport ticket or a two-sheet pick-up ticket, and are primarily collected by the accumulating device. When the number of the primarily accumulated sheets reaches a predetermined number (for example, 100), a belt or the like This is an apparatus for forming a bundle H by binding.

  The feeding amount of the band (binding band) necessary for bundling 100 accumulated paper sheets (hereinafter referred to as 100 sheet paper sheets) Ps goes around the outside of the 100 sheet paper Ps. Therefore, it is necessary to have a length that allows heat bonding by overlapping the ends. Conventionally, the feeding amount of the belt has been uniquely set according to the length (width) of the paper sheet in the short direction. For example, when the type of paper sheet to be processed (hereinafter referred to as ticket type) is set, the standard value of the width × length of the paper sheet is known. The feed amount of was set.

FIG. 9 is a diagram showing a conventional method for setting the feeding amount of the belt. When the ticket type to be processed is set, the feeding amount W of the belt is expressed by the following formula (1) where Ws is the standard width, Ts is the standard thickness Ts of 100 sheets Ps, and Wh is the length of the thermal bonding portion. ).
W = Ws + 2Ts + 2Wh (1)
Further, as an improvement of the conventional method, there is known a method of predicting the thickness when the quality level of the paper sheet is low / medium / high and setting the pressing force corresponding to the thickness ( For example, see Patent Document 1.)
JP 2007-102372 A (page 11-12, FIG. 7)

  However, the above-described method for setting the feeding amount of the band has a problem shown in FIG.

  FIG. 10 shows a state in which 100 sheets Ps are bundled using a band calculated based on the above equation (1).

  FIG. 10 (1) shows a case where the thickness of the 100-sheet paper Ps is small. For example, this is the case when the quality of 100 sheets Ps is better than the standard quality. In this case, there is a case where the feeding amount W of the belt is too large, and the belt protrudes from the end face of the 100 sheets Ps that are bound.

  FIG. 10 (2) shows a case where the thickness of the 100 sheet paper Ps is large. For example, this is the case when the quality of 100 sheets Ps is worse than the standard quality and the case of a non-conforming ticket. In this case, the belt feeding amount W is too small and the thermal bonding portion of the belt is insufficient. In this case, the band is easily peeled off.

  In addition, the method described in the above-mentioned patent document has a problem in that it cannot be set in detail according to the level of damaged paper sheets.

  The present invention has been made in order to solve the above-described problems, and includes a bundling device that can appropriately set the feeding amount of a band for bundling 100 sheets Ps according to the quality of the paper to be processed. An object of the present invention is to provide a paper sheet processing apparatus.

  In order to achieve the above object, a paper sheet processing apparatus according to claim 1 of the present invention comprises a take-out means for taking out paper sheets one by one from the supply section to which paper sheets are supplied in a batch at regular intervals. On the basis of the determination result by the conveyance means for conveying the paper sheet taken out by the means, the paper sheet determination means for determining the paper sheet conveyed by the conveyance means, and the paper sheet determination means. A conveyance control unit that sets a conveyance destination of paper sheets, a stacking unit that stacks the paper sheets whose conveyance destination is set by the conveyance control unit, and a predetermined number of sheets stacked by the stacking unit. A paper sheet processing apparatus comprising: a bundling unit that binds the reached paper sheet bundle with a bundling material, wherein the paper sheet discriminating unit discriminates a degree of contamination of the paper sheet as a damage level. The bundling means includes a front and rear discriminating means. Average value calculating means for calculating an average value of the damage levels of the bundle of paper sheets accumulated by the collecting means, and based on the average value of the damage levels calculated by the average value calculating means, A length setting means for setting the length, and the sheet bundle is bundled with a binding material having a length set by the length setting means.

  According to the present invention, since the feeding amount of the band for bundling 100 sheets Ps is appropriately set according to the quality of the paper sheet to be processed, it is possible to prevent the bundling failure such as the band being too long or too short.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a paper sheet processing apparatus 1 equipped with a bundling apparatus (bundling means) according to a first embodiment of the present invention. The paper sheet processing apparatus 1 determines whether the paper sheet P such as securities is genuine (true or fake) or correct (whether it can be redistributed or non-recyclable). The correct ticket is accumulated in the accumulating device 30, the lost ticket is accumulated in the accumulating device 31, and the indistinguishable ticket is accumulated in the rejected ticket accumulating device 33. The correct bills or the damaged bills collected in this way are bundled by the bundling device 40 or 41 arranged at the lower part of each stacking device. In addition, a conveyance abnormality ticket such as a two-sheet pickup ticket or a skew is accumulated in the reject ticket accumulation box 34.

  The paper sheet processing apparatus 1 is provided with a supply unit 10 that collectively supplies the accumulated paper sheets P. The paper sheets P accumulated in the supply unit 10 are taken out one by one at regular intervals by a take-out rotor (take-out means) 10A, and are carried by a carrying path (carrying means) 20.

  In this way, the paper sheet P taken out from the supply unit 10 by the take-out rotor 10A is discriminated by the paper sheet discriminating device (paper sheet discriminating means) 50. The paper sheet discriminating device 50 detects and discriminates the physical characteristics of the paper sheet P, and is composed of a plurality of devices, and is provided in the transport path 20 toward the downstream in the transport direction. In addition, the stacking device 30 that stacks the paper sheets P determined to be genuine based on the determination result of the paper sheet determination device 50, the stacking device 31 that stacks the paper sheets P determined to be non-payment, and the fake A reject ticket stacking device 33 for stacking tickets or reject tickets is provided.

  The take-out detection unit 51 detects the take-out state of the paper sheet P taken out from the supply unit 10 and transmits the detection result to the transport control unit 2. If the detection result of this take-out state is, for example, a pick-up error such as picking up multiple sheets such as two picks or clogging of the transport pitch, there is a problem such as failure to sort by the sorting gate that transports and processes downstream in the transport direction. Since it is likely to occur, the conveyance abnormality is transmitted to the conveyance control unit 2.

  When the conveyance control unit 2 receives the conveyance abnormality, the conveyance control unit 2 conveys the paper sheet P along the conveyance path 21 by rotating the sorting gate G40 that distributes the conveyance direction of the paper sheet P. And collected in the reject ticket storage 34. Note that the rejected tickets accumulated in the rejected ticket stacking box 34 can be supplied again.

  The rejection ticket stacking device 33 stacks the paper sheets P removed by the paper sheet discriminating device 50, and includes a stacking impeller 33 </ b> A and a temporary stacking box 33 </ b> B and has been transported along the transport path 26. The collected paper sheet P is received by the accumulating impeller 33A and accumulated in the temporarily accumulating piece 33B.

  As a result of the discrimination by the paper sheet discriminating device 50, the correct bills are accumulated in the temporary accumulation unit 30B of the accumulation device (accumulation means) 30 and the damaged bills are accumulated in the temporary accumulation unit 31B of the accumulation device (accumulation means) 31. . The classification of the correct bill and the damaged bill is performed by the paper sheet discriminating apparatus 50 to determine the degree of contamination of the conveyed paper sheet P. As a result of the determination, a level indicating the degree of contamination of the paper sheet P (this level is referred to as a normality level) is given.

  The sheet processing apparatus 1 can set a damage determination level for this damage level. For example, when the damage determination level is set to 5 in 10 stages, the conveyed sheet P If the damage level is 5 or more, it is determined as a correct ticket, and if it is less than 5, it is determined as a damaged ticket. Therefore, whether it is a correct ticket or a damaged ticket, all the paper sheets P included in it are assigned a correct level.

  In the stacking device 30 or 31, the paper sheets P are stacked in the temporary stacking unit 30 </ b> B or 31 </ b> B until the paper sheet P reaches a predetermined number (for example, 100 sheets) as a result of the determination by the paper sheet determination device 50. When the number of sheets P stacked in this way reaches 100 (100 sheets), the sheet P is delivered to a bundling device disposed below the stacking device 30 or 31. The bundling device 40 or 41 forms the bundle H by bundling the 100 sheets Ps with a band as a bundling band.

  The bundle H bundled in this way is bundled and conveyed by the conveyor 70 to the 10 bundle binding apparatus 80.

  The ten bundle binding device 80 stacks the small bundles H conveyed by the conveyor 70 until the ten bundles are formed, and further bundles every ten bundles to form a bundle (not shown).

  The bundle formed in this way is discharged out of the apparatus.

  FIG. 2 is a block diagram for explaining the operation of the stacking apparatus and bundling apparatus of the present invention shown in FIG.

  The conveyed paper sheet P is discriminated by the paper sheet discriminating device 50. The determination result is transmitted to the conveyance control unit 2.

  The transport control unit 2 transmits the determination result to the stacking / binding control unit 40A, determines the transport destination of the transported paper sheet P, and determines the branch gate G30 or G31 disposed in the transport path 20 Control and stack in the stacking device 30 or 31. Hereinafter, an example in which 100 sheets Ps accumulated in the accumulating device 30 are bundled by the bundling device 40 will be described. The same applies to the case where the 100 sheets Ps accumulated in the accumulation device 31 are bundled by the bundling device 41.

  When the number of sheets P stacked on the sheet stacking apparatus 30 reaches a predetermined number 100 (100 sheets), the stacking / binding controller 40A moves the 100 sheets Ps to the lower part To the bundling device 40 arranged in

  The bundling device 40 includes a band feed pulse motor 40B, a cutter solenoid 40C, a cutter 40D, a heater drive motor 40E, a heater 40F1, a shutter drive motor 40G, a shutter 40H, a push plate drive motor 40G, a push plate 40J, and a receiving plate 40K. Is done. The bundling device 40 configured as described above performs an operation described later, whereby the 100 sheets Ps are bundled to form a bundle H.

  FIG. 3 is a stacking / binding process flowchart for explaining the operations of the stacking device 30 and the binding device 40. In addition, since the operation | movement in the stacking apparatus 31 and the bundling apparatus 41 is also the same as that of the flowchart shown in FIG. 3, the description is abbreviate | omitted.

  First, the passage of the paper sheet P is detected at the entrance of the stacking device 30 (S1). As a result of the passage detection, when there is no paper sheet (No in S1), monitoring is performed until the paper sheet P passes. When the paper sheet P is detected by the passage detection (Yes in S1), the number of stacked sheets (passed sheet number) is counted up (coefficient) (S2).

At the same time, the total value of the non-use ticket level is calculated. For example, assuming that the loss ticket level of the paper sheet P with the n-th stack is Cfn, the total value Cfs of the previous loss ticket level is calculated by the following equation (2). Note that the total value Cfs of the loss ticket level is calculated for 100 sheets Ps that are units of accumulation or bundling.
Cfs ← Cfs + Cfn (2)
Cfs: Total value of non-performing ticket level Cfn: n-th non-conforming ticket level Next, it is confirmed whether the stacking number has reached 100 (S4).

  As a result of the confirmation in S4, if it has not reached 100 sheets (No in S4), the process returns to S1, and the counting of the number of stacked sheets and the addition of the loss ticket level is continued until the number of stacked sheets reaches 100 sheets.

As a result of the confirmation in S4, when 100 sheets are reached (Yes in S4), the total value Cfs of the stipend level calculated by the above equation (2) is divided by the number of stacked sheets (100), and the following equation (3) The average value Cfav of the non-performing ticket level indicated by (5) is calculated (S5).
Cfav ← Cfs / 100 (3)
Cfav: Average value of non-performing ticket level Cfs: Total value of non-performing ticket level

  Next, the stacking / binding controller 40A shifts to a binding process that is a subroutine process using the calculated average value Cfav of the non-performing bill level as an argument (S6). Details of the bundling process (S7), which is a subroutine process, are shown in FIG.

  FIG. 4A is a flowchart showing the operation of the bundling process which is a subroutine process. FIG. 4 (2) shows a band feed pulse table. 5 to 8 are schematic diagrams for explaining the operation of the bundling process. FIG. 5 shows a state before the paper sheets P are accumulated. The paper sheets P are stacked in the stacking box 30B in this state to become 100 sheets of paper sheets Ps. Hereinafter, description will be made with reference to FIGS.

  First, 100 sheets are stacked (see FIG. 6). At the time when the 100 sheets are collected, the pulse table of the band feeding amount corresponding to the above-mentioned average value Cfav of the banknote level is selected (S10, refer to FIG. 4 (2)).

  Next, the number of pulses selected from this pulse table is set in the band feed pulse motor 40B, the band feed pulse motor 40B is driven, and the band K corresponding to the number of pulses is sent. After completion of the band feeding operation, the cutter solenoid 40C is driven, and the band feeding end is cut by the cutter 40D (S11, see FIG. 7).

  Next, the shutter drive motor 40G is driven, the shutter 40H at the bottom of the stacking device 30 is opened, the push plate drive motor 40I is driven, and the 100 sheets Ps are pressed against the receiving plate 40K by the push plate 40J (S12, FIG. 7).

  Next, the heater drive motor 40E is driven to move the heater 40F1 to the thermal bonding position. During this movement, the folding plate 40F2 is also driven in conjunction with the heater drive motor 40E.

  The folding plate 40F2 is disposed so as to be pivotable about a fulcrum provided at the end of the receiving plate 40K, operates in conjunction with the heater drive motor 40E, and the belt K is placed on the outer periphery of the 100 sheets Ps. Fold along. As a result of this folding, both ends of the belt K are folded on the upper surface of the 100 sheets Ps, resulting in a single winding state. In this way, the heater 40F1 is pressed against the band K wound around the 100 sheets Ps, and the band K is thermally bonded (S13, see FIG. 8).

  Next, the heater drive motor is driven, the heater 40F1 is drawn in, and the bundle H formed by heat bonding is discharged.

  As described above, according to the present embodiment, when the quality of the 100 sheets Ps is low, for example, when the quality of the 100 sheets Ps is poor, the average value of the above-mentioned non-performing ticket level. Cfav becomes a low value, and the thickness of 100 sheets Ps becomes thick. In this case, the one cut so that the length of the band K becomes longer is used. On the other hand, when the quality of the 100-sheet paper sheet Ps is good, the average value Cfav of the above-mentioned non-performing ticket level becomes a high value, and the thickness of the 100-sheet paper sheet Ps becomes thin. In this case, the one cut so that the length of the band K is shortened is used.
