Description

  The present invention relates to a paper sheet processing apparatus that processes paper sheets such as securities, a paper sheet cutting apparatus mounted on the paper sheet processing apparatus, and a driving method of the paper sheet cutting apparatus.

  FIG. 9 shows an internal configuration of a conventional paper sheet cutting apparatus. This paper sheet cutting device is used by a device that cuts a conveyed paper sheet alone, and when a paper sheet such as securities is discriminated by a paper sheet discriminating apparatus, and based on the discrimination result In some cases, it is used by being incorporated in a paper sheet processing apparatus for sorting leaves. Here, the prior art will be described for the latter case.

  A paper sheet processing apparatus for processing paper sheets such as securities takes out and transports a batch of paper sheets that are input at a time, one by one, and the type of the paper sheet is determined by a paper sheet discrimination device. (Hereinafter referred to as ticket type) Discrimination, conveyance direction discrimination, true / false discrimination (whether true or fake) and correctness / injury (whether it can be redistributed or non-redistributable) This is a device that sorts paper sheets based on the determination result, and distributes and processes them into a stacking / sealing device, a cutting device, or the like.

  At this time, the paper sheet determined to be a non-performing paper is cut by a paper sheet cutting device. A conventional paper sheet cutting apparatus includes a disk-shaped cutting blade 6120 for cutting a paper sheet, a timing pulley fixed coaxially with the rotation axis of the cutting blade 6120, a driving motor 6140, and this timing pulley. The cutting blade 6120 is rotated by the timing belt A 6130 that connects the driving motor and transmits the driving force to the timing pulley, and the paper sheet P is cut.

  In addition, a timing belt B6200 is provided for connecting the timing pulley and the conveyance roller timing pulley fixed to the rotation shaft of the conveyance roller for driving the conveyance belt for taking the paper sheet into the paper sheet cutting device. The conveyance belt is configured to rotate in a direction in which the paper sheet is guided to the paper sheet cutting device as the blade rotates.

There are restrictions on the number of drive motors that can be stacked and the capacity of the paper sheet processing device depending on the size and power consumption. Regarding the periphery of the paper sheet cutting device, there is a paper sheet on the transport path immediately before the cutting blade. Due to security restrictions that must always be cut, it is necessary to limit the transport direction of the transport belt immediately before to the cutting blade (positive direction) when driven by a drive motor. As the cutting conditions for the leaves, it is necessary that the rotation of the cutting blades and the conveying speed of the paper sheets be synchronized. For example, as shown in the drawing, the timing belt B and the conveying belt driving roller are moved from the cutting blade driving motor. Therefore, this type of paper sheet cutting apparatus is known (for example, see Patent Document 1).
JP 2002-192002 (Page 5-6, FIG. 1)

  However, in the paper sheet processing apparatus described in Patent Document 1, since the drive shaft is integrated for the purpose of synchronizing the conveying belt speed and the cutting blade rotation speed and reducing the overall size of the apparatus, the cutting blade Cannot be rotated forward or reverse independently only by the normal rotation in the same direction as the normal conveyance direction. Such rotation of the cutting blade in only one direction (forward rotation) tends to cause clogging of the cut pieces and accumulation of adhesives, and there is a problem that the cutting blade may stop rotating due to an increase in rotational load. In such a case, by manually rotating or reversing the cutting blade manually, clogged cutting pieces are removed and the load is reduced.

  As a method of solving this kind of problem without using the above-described manual method, there is a method of increasing the driving force of the driving motor that rotates the cutting blade. However, in this case, there is a problem that not only power consumption increases but also a large space is required.

  In addition, as described above, when the cutting blade stops in the middle of cutting, a paper sheet in the middle of cutting is generated, whether it is a paper sheet to be cut or a paper sheet that should not be cut. It is difficult to make a determination, and there is a problem that even when performing an initialization process after a normal jam process, it is left to the operator's determination without rotating the cutting blade. That is, when the paper sheet cutting device stops due to clogging or the like, there is a problem that the subsequent processing becomes complicated.

  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 paper sheet cutting apparatus 60 according to a first embodiment of the present invention. First, the configuration of the paper sheet processing apparatus 1 will be described with reference to FIG. The paper sheet processing apparatus 1 can authenticate the genuine paper sheet P such as banknotes (whether it is a genuine note or a fake ticket) or not (reflowable genuine note (first paper sheet)) or cannot be recirculated. The correct ticket is classified by the stacking / sealing devices 30 to 33 for each type of the paper sheet P, and then bundled every 100 sheets with a paper band. To form a bundle. The bundles formed in this way are discharged to the conveyor 70, lifted by the lifter 70A, and accumulated every 10 bundles, and further bundled by the large band bundling device 71. On the other hand, the slip is cut by the paper sheet cutting device 60, and the cut pieces are discharged out of the device by an air pipe. The discharged pieces are collected in a storage box (not shown). Details will be described below.

  The paper sheet processing apparatus 1 is provided with a supply unit 10 that collectively feeds the stacked paper sheets P. The paper sheets P stacked on the supply unit 10 are taken out one by one at regular intervals by the take-out roller 10A, and are supplied to the transport path (transport means) 20. The take-out roller 10A takes out one sheet of paper P every rotation. The conveyance path 20 includes conveyance rollers (not shown) and a conveyance belt (not shown), and conveys the paper sheet P from the upstream in the conveyance direction to the downstream.

  In this manner, the paper sheet P supplied from the supply unit 10 by the take-out roller 10A is determined by the paper sheet determination unit (paper sheet determination unit) 50. The paper sheet discriminating unit 50 detects and discriminates the physical characteristics of the paper sheet P, and includes a plurality of paper sheet discriminating devices 52A to 56. Is provided. Further, based on the discrimination results of these paper sheet discriminating devices 52A to 56, the discriminating means classifies the bill into a correct ticket, a non-performing ticket, and an excluded ticket. The correct ticket is divided into the stacking / sealing devices 30 to 33 for each ticket type by the branch gates G30 to G32, the lost ticket is divided into the paper sheet cutting device 60 by the branch gate G60, and the rejected ticket is sent to the rejected ticket stacking device 40. It is divided.

  The take-out detection unit 51 detects the take-out state of the paper sheet P supplied from the supply unit 10 and notifies the control unit (control means) 2 of the detection result. If the detection result of this removal state is, for example, when multiple sheets are picked up or the conveyance pitch is clogged, troubles such as being unable to be distributed by the sorting gate that is conveyed and processed downstream in the conveyance direction are likely to occur. The control unit 2 is notified. The control unit 2 receives the notification of the take-out abnormality and rotates the sorting gate G40 that sorts the transport direction of the paper sheet P to the left to transport the paper sheet P along the transport path 21 and eliminate it. It is accumulated in the ticket accumulation unit 41. The paper sheets P accumulated in the rejection ticket accumulation unit 41 can be supplied again.

  The paper sheet discrimination devices 52 </ b> A to 52 </ b> B have a paper sheet P ticket type discrimination or damage discrimination function. For the ticket type discrimination, when the paper sheet P is a Japanese banknote, a denomination consisting of 1,000 yen, 2,000 yen, 5,000 yen, and 10,000 yen and a conveyance state (upright / inverted, front / back) are discriminated. In addition, the discrimination of whether or not the paper is correct is made by determining whether the paper sheet is a correct paper sheet (first paper sheet) or a paper money card (second paper sheet).

  The paper sheet discriminating device 52C has a function of detecting the shape of the paper sheet P, detects the length, width, hole, tear, and the like of the paper sheet P and notifies the control unit 2 of the detection result. When the length and width of the paper sheet P exceed the set value of the set ticket type, it becomes an exclusion ticket. Further, if the hole, tear, cut, etc. of the paper sheet P exceed the set value, it becomes a non-use ticket.

  The paper sheet discriminating devices 54A and 54B have a magnetic detection function for the paper sheet P, detect the magnetic material amount of the paper sheet P, and notify the control unit 2 of the detection result.

  The paper sheet discriminating devices 54C and 54D have a fluorescence detection function for the paper sheet P, detect the amount of phosphor of the paper sheet P, and notify the control unit 2 of the detection result. When the phosphor of the paper sheet P exceeds a set value, or when a predetermined amount of the phosphor does not exist at a predetermined location of the paper sheet, it becomes an exclusion ticket.

  The paper sheet discrimination device 55 has a function of detecting the thickness of the paper sheet P, detects the thickness of the paper sheet P, and notifies the control unit 2 of the detection result. If the thickness of the paper sheet P exceeds the set value, it becomes an exclusion ticket.

  The paper sheet discriminating device 56 has a tape sticking detection function and detects a tape stuck to the paper sheet P. If the tape sticking size is within the set value, it becomes a non-paid ticket, and if it exceeds the set value, it becomes a rejected ticket.

  As a result of the processing of the paper sheet discriminating devices 52A to 56, the correct bill is supplied to the stacking / sealing devices 30 to 33, the lost ticket is supplied to the paper sheet cutting device 60, and the rejected ticket is the rejected ticket stacking device 40. To be supplied.

  Since the stacking / sealing devices 30 to 33 are similarly configured, the stacking / sealing device 30 will be described here. The stacking / sealing device 30 includes a stacking impeller 30A, a stacking unit 30B, and a sealing unit 30C. The stacking / sealing devices 31 to 33 are configured in the same manner as the stacking / sealing device 30. The operation of the stacking / sealing device configured as described above will be described below.

  In the stacking / sealing device 30, the first 100 sheets P of paper sheets P that have been determined to be genuine as a result of the processing of the paper sheet determination devices 52 </ b> A to 56 </ b> 56 are stacked. At this time, the sorting gate G30 is rotated to the right, and the paper sheet P is transported through the transport path 22 and stacked on the stacking unit 30B of the stacking / sealing device 30 including the stacking impeller 30A. With the passage of 100 sheets, the sorting gate G30 is rotated to the left side to prevent the sheets P from being continuously accumulated, and the sorting gate G31 is rotated to the right side to continuously convey the 101th and subsequent sheets. The genuine paper sheet P is conveyed to the stacking / sealing device 31. 100 genuine paper sheets P collected in the stacking unit 30B of the stacking / sealing device 30 are transferred to the sealing unit 30C and sealed with a paper strip (not shown) to form a small bundle. Similarly, when the correct number of sheets collected in the stacking unit 31B of the stacking / sealing device 31 reaches 100, the sorting gate G31 is rotated to the left to prevent the sheets P from being continuously stacked. At the same time, the sorting gate G30 is rotated to the right, and the next 100 sheets are stacked on the stacking unit 30B of the stacking / sealing device 30.

  The stacking / sealing devices 32 and 33 are used for stacking different ticket types than those processed by the stacking / sealing devices 30 and 31. Further, the bundles sealed with paper strips every 100 sheets are conveyed to the left side by the conveyor 70, lifted by the lifter 70A, accumulated in the strap stacker 71, and further bundled into 10 bundles.

  The rejection ticket stacking device 40 stacks the paper sheets P excluded by the paper sheet discrimination device 50, and includes a stacking impeller 40A and a rejection ticket stacking unit 40B. Then, the paper sheets P conveyed along the conveyance path 22 are received by the accumulation impeller 40A and accumulated in the rejection ticket accumulation unit 40B.

  The cutter block unit 61 includes a cutting blade part (cutting means) that cuts the paper sheet P and a drive unit that drives the cutting blade part.

  The cutting blade portion is configured such that one cutting blade 611 in which disk-shaped blades are stacked on the same axis and the blade portion of the other cutting blade 612 having the same configuration are combined in a nested manner, and are rotatably arranged on the cutter block main body. ing.

  The drive unit includes a drive motor (drive motor) 614 and first transmission means for transmitting the drive force of the drive motor 614, and the drive motor is controlled by the control means so as to be capable of normal rotation or reverse rotation. The Details will be described later.

  The air feed pipe 63 is a device for discharging the cut pieces of the paper sheet P cut by the cutter block unit 61 to the outside of the body of the paper sheet processing apparatus 1, and the cut pieces and the paper dust generated when the paper sheet is cut at high speed. Is soaked from the outside so as not to flow back into the sheet processing apparatus.

  FIG. 3 is a mechanism diagram of the cutter block unit 61 of the paper sheet cutting device 60 of the present embodiment. FIG. 3A is a side view of the main part of the cutter block unit 61, and FIG. 3B is a front view of the main part of the cutter block unit 61. The cutter block unit 61 includes a cutting blade part and a driving unit that drives the cutting blade part.

  The cutting blade portion includes a plurality of disk-shaped blades stacked on a shaft 611A and a cutting blade (first cutting blade) 611 configured to be rotatable around the shaft, and a disk-shaped blade configured in the same manner as the shaft 612A. It is composed of cutting blades (second cutting blades) 612 that are stacked on top and configured to be rotatable about an axis. These cutting blades 611 and 612 are arranged so as to mesh with each other. The cutting blades 611 and 612 are connected by a gear (not shown) and are driven coaxially. In the embodiment, by driving the cutting blade 611, the cutting blade 612 rotates in reverse so as to be engaged.

  The first transmission means connects the timing pulley to the cutting shaft first pulley (timing pulley) 611B attached to the shaft 611A of the cutting blade 611 and the timing pulley 614A incorporated in the rotating shaft of the driving motor 614. A timing belt 613 is used. With this configuration, by driving the driving motor 614, the driving force is transmitted to the cutting blade 611 by the timing belt. The cutting blade 611 and the cutting blade 612 are connected, and the cutting blade 612 rotates as the cutting blade 611 rotates as described above.

  The feature of this embodiment is that an electromagnetic clutch / brake 617 is provided in the approximate center of the rotary shaft 611A of the cutting blade 611 described above, and the cutting shaft first pulley 611B is interlocked with the input shaft of the electromagnetic clutch / brake 617. A cutting shaft second pulley 611C is connected to the output shaft of the electromagnetic clutch / brake 617.

  The second transmission means includes a cutting shaft second pulley 611 </ b> C, a timing pulley 621 </ b> A incorporated in the rotation shaft of the conveying belt drive roller 621, and a timing belt B <b> 620 that connects these timing pulleys. As described above, when the driving motor 614 rotates, the cutting blades 611 and 612 rotate in the direction of cutting the paper sheet P, the transport belt driving roller 621 rotates, and the transport belt 622 cuts the paper sheet P. Carry in the direction you want. The conveyed paper sheet P is cut by the cutting blades 611 and 612 into a cut piece D.

  FIG. 4 shows an example of a cutting blade control pattern for preventing clogging of the cutting blades 611 and 612 of the paper sheet cutting device 60 as a driving method of the paper sheet cutting device. By temporarily separating the interlocking between the conveying belt 622 and the cutting blades 611 and 612 by turning on / off the electromagnetic clutch / brake 617 described above, the cutting blade portion (cutting means) constituted by the cutting blades 611 and 612 is made independent. Thus, forward or reverse control can be performed.

  FIG. 4A is an example of the cutting blade control pattern 1. Before starting the operation of the paper sheet processing apparatus 1, the cutting means is reversed for 4 s (first time) at a rotation speed of 200 rpm (first rotation speed) (first step).

  After the end of the first step, the cutting means is rotated forward for 4 s (first time) at a rotation speed of 200 rpm (first rotation speed) (second step).

  By doing in this way, clogging of the cutting blades 611 and 612 constituting the cutting means can be prevented. Since the cutting of the paper sheet P is performed in the normal direction, in order to prevent clogging, the paper sheet that has been clogged up first is released to prevent clogging, and then the paper sheet P is released by normal rotation. It is effective to cut and discharge paper sheets.

  FIG. 4B is an example of the cutting blade control pattern 2. Before the operation of the paper sheet processing apparatus 1, the cutting means is reversed for 2 s (first time) at a rotation speed of 50 rpm (first rotation speed) (first step).

  After the end of the first step, the cutting means is rotated forward at a rotation speed of 100 rpm (second rotation speed) for 3 s (second time) (second step).

  After the end of the second step, the rotation is reversed for 2 s (first time) at a rotation speed of 150 rpm (third rotation speed) (third process).

  After completion of the third step, the cutting means is rotated forward at a rotational speed of 200 rpm (fourth rotational speed) for 4 s (third time) (fourth step).

  In this method, when the load due to clogging is large, the cutting means is difficult to rotate, so that the reverse rotation is first performed at a low speed, and then the rotation speed is slightly rotated forward for a time longer than the reverse rotation time. Since clogging is improved by this process, the rotation speed is further increased to reverse the rotation. Next, there is a method in which the rotation speed is further increased to rotate forward to cut and discharge the paper sheets.

  As described above, a plurality of cutting blade control patterns for independently operating the cutting blades 611 and 612 (cutting means) are prepared, and information stored in the paper sheet processing apparatus 1, for example, the paper sheet P cut last time Paper of a certain ticket type with a high adhesion sticking rate using the type of sheet, the number of sheets cut at that time (previous number of sheets cut), or the number of sheets cut for the total number of devices in a certain period (total number of sheets cut) During the initialization operation after cutting the leaves P, a plurality of cutting blade control patterns can be selected and performed from a plurality of cutting blade control patterns so as to carefully reduce the load.

  As described above, according to the present invention, since an optimum cutting handle control pattern can be used according to the type and number of sheets of paper cut, the paper cutting apparatus is less likely to cause clogging of the cutting blade. Can be provided.

  FIG. 5 is a mechanism diagram of the cutter block portion 61A of the paper sheet cutting device 60 according to the second embodiment of the present invention. FIG. 5A is a side view of the main part of the cutter block unit 61, and FIG. 5B is a front view of the main part of the cutter block unit 61. Since the parts other than the solvent automatic dropping mechanism 623 shown in the second embodiment are the same as those in the first embodiment, the description thereof is omitted and the changed parts are described.

  The solvent automatic dropping mechanism 623 is injected by a solvent tank 623A for containing a solvent for melting the adhesive adhered to the cutting blades 611 and 612 and keeping the sharpness, a pump 623B for injecting the solvent, and a pump 623B. It is constituted by a hollow tube that guides the solvent to the cutting blade 611 or 612. With such a configuration, it is possible to ensure the sharpness of the cutting blade for a long time by injecting the solvent in accordance with the clogging preventing operation described above during the initialization operation after cutting. The reason why this type of solvent is necessary is that the paper sheets to be cut are non-useable, and the paper sheets themselves are often dirty, and the paper sheets that are attached with tape or the like are cut. This is to prevent the tape or the glue from adhering to the cutting blade 611 or 612 from being deteriorated by the dirt. Therefore, a solvent having a tape peeling effect is used as the solvent.

  In addition, this method is used to grasp the usage status of the cutting blade based on the previous cutting number or the cumulative cutting number according to the first embodiment, and injecting the solvent in accordance with the clogging prevention operation during the initialization operation of the paper sheet processing apparatus. By doing so, it is possible to prevent the sharpness of the cutting blade from being deteriorated.

FIG. 6 is an example of a cutting blade control pattern (pattern 1 to pattern 3) and automatic solvent dripping control, which are driving methods of the paper sheet cutting apparatus according to the second embodiment. In the following, there are four types of paper sheets, A, B, C and D. The adhesion rate of the sticky material is shown by the following formula (1), and the complexity of the cutting blade control pattern is shown by the following formula (2). The case will be described. The cutting blade control pattern is more complicated in FIG. 4B than in the above-described FIG. 4A, and the cutting blade control pattern prevents clogging of the cutting blade and contamination of the cutting blade. Great effect.
Adhesion rate: A>B>C> D ... (1)
A, B, C, D: Paper sheet type cutting blade control pattern complexity: Pattern 1 <Pattern 2 <Pattern 3 (2)
As a setting method of the cutting blade control pattern and the automatic solvent dropping timing, the cutting blade control pattern and the automatic solvent dropping timing are selected according to the type of the paper sheet and the number of cut sheets or the total number of cut sheets. In the illustrated example, a complicated cutting blade control pattern is used as the previous cutting number increases. Moreover, every time the cumulative number of cut sheets reaches a predetermined value, the solvent is automatically dropped. That is, when cutting the number of in the sheet processing apparatus 1 type of sheet is cut upon batch paper sheets is A (last cut sheets) than 1000 sheets (10 ³⁾ cut Clogging prevention by the blade control pattern 2 is performed. Same denomination processing has been further continued, cutting the number of that time in the case of 10000 sheets (10 ^four ~) performs clogging prevention by the cutting blade control pattern 3. Although during normal cutting process performs clogging prevention by such a method, if the total cut number reached 100 million copies (10 per ^six), anti-clogging and solvent automatically by the cutting blade control pattern 1 The dripping process is performed.

  Similarly, when the type of the paper sheet is other than A, the cutting blade control pattern and the timing for automatically dropping the solvent are selected according to the previous cutting number and the cumulative cutting number.

  As described above, according to the present invention, in addition to the effect of the first embodiment, the adhesive can be dissolved by the solvent, so that the cutting blade can be prevented from being clogged.

  FIG. 7 is a diagram illustrating forced cutting according to the third embodiment of the present invention. The third embodiment is the same as the first embodiment except that a sensor 625 for detecting a paper sheet is provided while the paper sheet conveyed by the conveying belt 622 is transferred to the cutting blades 611 and 612. The description will be omitted and the changed part will be described.

  In this embodiment, when the operation of the paper sheet processing apparatus 1 is stopped due to a sudden conveyance jam or the like, the paper sheet P in the middle of cutting remains uncut or is likely to remain, and is detected by the sensor 625. In such a case, the electromagnetic clutch / brake 617 separates the synchronization between the cutting blade and the conveyor belt 622, and the cutting blades 611 and 612 are independently rotated forward. As a result, the paper sheets being cut are forcibly cut.
