Description

  The present invention relates to a paper sheet processing apparatus and a paper sheet processing method in which a paper sheet is sandwiched between a pair of films, and the film is wound and stored by a winding roller.

  2. Description of the Related Art Conventionally, a paper sheet processing apparatus that receives paper sheets such as banknotes, checks, and cash vouchers, temporarily stores them, and performs a payout process thereof is known. For example, an apparatus that handles banknotes as paper sheets is mounted on an automated teller machine (ATM) or the like as a cash processing apparatus such as a banknote depositing and dispensing machine.

  In the paper sheet processing apparatus, a paper sheet fed through a conveyance path is sandwiched between a pair of films, and the pair of films sandwiching the paper sheets is wound up by a winding roller to temporarily store the paper. Some have a take-up type storage unit for storing leaves. Paper sheets sandwiched between films temporarily taken up by a take-up roller can be taken out by rewinding the film by rotating the take-up roller in reverse.

  In the paper sheet processing apparatus adopting such a winding method, the short direction of the paper sheet is the same as the winding direction of the winding roller in order to increase the storage amount of the paper sheet. There is a device that performs winding as described above (see, for example, Patent Document 1). There is also a device that stores paper sheet intervals in the order of storage when winding paper sheets, and variably controls the feeding speed based on the paper sheet interval information stored at the time of feeding (for example, Patent Documents). 2).

  However, in the conventional paper sheet processing apparatus having a winding-type storage unit, it is difficult to reduce the size and cost of the apparatus because it is necessary to suppress variations in the paper sheets at the time of discharge. It was.

  In a paper sheet processing apparatus having a take-up type storage unit, a variation occurs in the position of a paper sheet sandwiched between films depending on the direction of the paper sheet at the time of loading and the subsequent processing. If the banknotes stored in the film are discharged as they are with variations in position, the discharge positions of the paper sheets will vary. For this reason, inconveniences such as difficult to take out the discharged paper sheets or not fit in the cassette for storing the discharged paper sheets occurred. Therefore, a dedicated centering mechanism for bringing the paper sheets to the central area of the entrance / exit is provided on the conveyance path, and the position of the paper sheets sandwiched between the films is brought to the central area. However, since a dedicated centering mechanism is provided, there is a problem that not only the apparatus is increased in size but also the cost is increased.

  In particular, when paper sheets temporarily sandwiched between films are moved through a plurality of transport paths and taken out into a plurality of cassettes, a cassette or a number of centering mechanisms corresponding to the transport paths must be provided. In other words, an increase in the size of the paper sheet processing apparatus could not be avoided.

  In view of the above, an object of the present invention is to provide a paper sheet processing apparatus and a paper sheet processing method that can store the discharge position of paper sheets within a predetermined area without having a dedicated centering mechanism. And

  In order to solve the above-described problems, a paper sheet processing apparatus is provided in which a paper sheet is sandwiched between a pair of films, and the film is wound and stored by a winding roller. The sheet processing apparatus includes a sensor that detects the position of the sheet on the conveyance path, a correction amount calculation unit that calculates a correction amount, and a position control unit that controls the position of the winding roller.

  The paper sheet moves on a conveyance path for conveying the paper sheet between the width direction of the winding roller perpendicular to the film winding direction and the paper sheet entrance / exit. The sensor detects a position corresponding to the width direction of the winding roller of the paper sheet moving on the conveyance path. The correction amount calculation means compares the position of the paper sheet detected by the sensor with a predetermined area preset with respect to the entrance and exit when the paper sheet is stored in the take-up roller. The amount of protrusion outside the area is calculated. Based on the amount of protrusion, a correction amount for storing the paper sheet in a predetermined area is calculated, and the movement direction of the winding roller is determined to determine the movement amount of the winding roller. Then, correction information in which the movement amount of the take-up roller is associated with the sheet storage order is stored in the correction information storage means. The position control means reads the correction information from the correction information storage means when discharging the paper sheets stored in the take-up roller, and moves the take-up roller corresponding to the next paper sheet to be released based on the storing order. Extract the amount. Then, the moving means for moving the winding roller in the width direction of the winding roller is controlled based on the extracted movement amount, and the discharge position of the paper sheet is stored in a predetermined area.

  Moreover, in order to solve the said subject, the paper sheet processing method which performs the process sequence of said paper sheet processing apparatus is provided.

  According to the disclosed paper sheet processing apparatus and paper sheet processing method, when the paper sheet is stored, the movement amount of the winding roller for centering is calculated, and the winding roller is moved based on the roller movement amount. Position control. Thereby, the discharge position of the paper sheets can be stored in a predetermined area. As a result, it is possible to store the discharge position of the paper sheets within a predetermined region without having a dedicated centering mechanism, and the apparatus can be reduced in size and cost.

Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a diagram showing the concept of the invention applied to the embodiment.
The paper sheet processing apparatus 1 includes a take-up roller 1a that sandwiches and winds a paper sheet in a film, a sensor 1b that detects the position of the paper sheet, a correction amount calculation unit 1c that calculates a correction amount, and a correction that stores correction information. The information storage means 1d, the position control means 1e for controlling the position of the winding roller 1a based on the correction information, and the moving means 1f for moving the winding roller 1a are provided.

  The paper sheet 20 is taken in from the entrance / exit 1g provided in the paper sheet processing apparatus 1 and stored in the apparatus, and the stored paper sheet 20 is discharged from the entrance / exit 1g. Note that when the paper sheet 20 is discharged, the discharge position of the paper sheet 20 is suppressed within a predetermined region for the purpose of making it easier to take out the discharged paper sheet 20. Hereinafter, this predetermined area set for the width of the entrance / exit 1g is referred to as a centering area w1.

  The winding roller 1a is disposed in the apparatus so as to face the entrance / exit 1g, and winds and rewinds a pair of films sandwiching the paper sheet 20. The winding of the film is a storing operation of the paper sheet 20, and the paper sheet 20 moves in the apparatus in the storing direction shown in FIG. Rewinding the film is a discharging operation of the stored paper sheet 20, and the paper sheet moves in the discharging direction shown in FIG. The winding roller 1a can be moved in the width direction of the winding roller 1a by the moving means 1f. In the example of FIG. 1, it can move to the left and right of the figure.

  The sensor 1b is disposed on the conveyance path of the paper sheet 20 that connects the winding roller 1a and the entrance / exit 1g. And the position of the width direction of the winding roller 1a of the paper sheet 20 which passes on a conveyance path is detected. For example, in the case of the position coordinates from left to right in FIG. 1, when the passing paper sheet 20 is detected, the minimum point (leftmost point) 20a and the maximum point (rightmost point) of the paper sheet 20 are detected. 20b is detected. The detected position of the paper sheet 20 is notified to the correction amount calculation means 1c.

  The correction amount calculation means 1c obtains the position of the paper sheet 20 detected by the sensor 1b when the paper sheet 20 taken in from the entrance / exit 1g is stored in the take-up roller 1a, and from the centering area w1 of the paper sheet 20 The amount of protrusion is calculated. For example, the minimum point (minimum position coordinate) 20a and the maximum point (maximum position coordinate) 20b of the paper sheet 20 in the horizontal direction detected by the sensor 1b are compared with the range (position coordinates of both ends) of the centering area w1. It is determined whether the minimum point 20a or the maximum point 20b is not out of the centering region w1. When the distance is off, the distance from the minimum point 20a or the maximum point 20b outside the centering area w1 to the end of the nearest centering area w1 is calculated as the amount of protrusion, and the protruding part is stored in the centering area. Therefore, the centering correction amount necessary for this is calculated. In the simplest case, the amount of protrusion is the centering correction amount. In addition, the direction in which the take-up roller 1a is moved is defined as the moving direction of the take-up roller 1a in order to accommodate the protruding portion within the centering region. For example, when the minimum point 20a of the paper sheet 20 is outside the centering region w1, the distance from the minimum point to the closest end of the centering region w1 is set as the correction amount. The direction from the minimum point 20a toward the centering region w1 is defined as the moving direction of the winding roller 1a. When the minimum point 20a and the maximum point 20b of the paper sheet 20 are both within the centering area w1, the correction amount is set to zero. Thus, the winding roller movement amount is calculated based on the calculated correction amount and the moving direction of the winding roller 1a. The movement amount of the winding roller represents that the winding roller 1a is moved by a correction amount in the moving direction of the winding roller 1a from the state where the winding roller 1a is at the center. Correction information is generated by associating the calculated correction amount and take-up roller movement amount with the storage order of the corresponding paper sheets 20, and stored in the correction information storage unit 1d.

  Further, the amount of protrusion may be the amount of protrusion of the center of the sheet 20 and the center of the centering region w1 instead of the amount of protrusion of the sheet 20 from the centering region w1. Based on the coordinates of the position of the paper sheet 20 detected by the sensor 1b and the coordinates of the centering area w1, a correction amount corresponding to the distance between the center of the paper sheet 20 and the center of the centering area w1 is calculated. Furthermore, the direction in which the winding roller 1a is moved for centering is defined as the moving direction of the winding roller 1a. Then, the amount of movement of the take-up roller is calculated in the same manner as described above. When calculating the amount of protrusion, a predetermined threshold value may be set, and the correction amount may be calculated only when the deviation of the center point exceeds the predetermined threshold value. The calculated correction amount and take-up roller movement amount are associated with the storage order of the corresponding paper sheets 20 and registered in the correction information.

The correction information storage unit 1d stores the correction information generated by the correction amount calculation unit 1c.
The position control means 1e reads the correction information stored in the correction information storage means 1d when discharging the paper sheet 20 accommodated in the take-up roller 1a, and next takes up the take-up roller of the paper sheet 20 to be released. Extract the amount of movement. Since the discharge is performed in the reverse order of the storing order, the next sheet 20 to be discharged can be specified based on the storing order. Then, the moving means 1f for moving the winding roller 1a in the width direction is driven based on the moving amount of the winding roller of the paper 20 to be released next, and the winding roller 1a is moved to a desired position.

The moving means 1f moves the winding roller 1a in the width direction of the winding roller 1a based on the movement amount (the magnitude and direction of movement) instructed by the position control means 1e.
Next, the operation of the sheet processing apparatus will be described. FIG. 2 is a diagram showing an outline of the operation of the paper sheet processing apparatus. FIG. 2A shows when the paper sheet is stored, and FIG. 2B shows when the paper sheet is released.

  2A, the papers 21 and 22 move along the transport path in the storage direction (the direction from the entrance / exit 1g toward the take-up roller 1a) in the order of the paper 21 and the paper 22. The sensor 1b detects the position in the width direction (horizontal direction in the figure) of the paper 21, the paper 22, and the take-up roller 1a of the paper sheets that are sequentially taken. In the example of FIG. 2, the position of the leftmost minimum point 22a and the position of the rightmost maximum point 22b are detected in the width direction of the winding roller 1a. The correction amount calculation means 1c acquires the positions of the minimum point 22a and the maximum point 22b as the positions of the paper 22 from the sensor 1b, and compares them with the centering region w1 to calculate the amount of protrusion. In this case, the distance between the right end of the centering region w1 and the maximum point 22b is calculated as the protrusion amount 32. Then, as a correction amount necessary to fit the paper 22 in the centering area, a value that is at least equal to the protrusion amount 32 or a margin is calculated. Further, in order to store the paper 22 that protrudes to the right of the centering area w1 and is accommodated in the take-up roller 1a into the centering area at the time of discharge, the take-up roller 1a is moved leftward with respect to the transport path and discharged. do it. Therefore, the moving direction of the winding roller 1a is the left direction from the maximum point 22b toward the centering region w1. The combination of the correction amount (the magnitude of the moving distance) and the moving direction of the winding roller 1a is the winding roller moving amount. The correction amount and the take-up roller movement amount are associated with each other in the storing order and registered in the correction information. For example, when the paper 21 is in the storage order “1”, the correction amount and the take-up roller movement amount are registered in association with the storage order “2” of the paper 22. The paper 22 is sandwiched between films while maintaining the position of the take-up roller 1a in the width direction, taken up by the take-up roller 1a, and stored.

  (B) At the time of discharge, the papers 21 and 22 move on the transport path in the discharge direction (the direction from the winding roller 1a toward the entrance / exit 1g) in the order of the paper 22 and the paper 21. Here, it is assumed that the paper 21 and the paper 22 are stored in this order, and then the discharge process is performed. Before discharging the paper 22, the position control unit 1e reads the correction information, and specifies the paper having the largest storage order value (the latest stored). In the example of FIG. 2, the correction information on the paper 22 is read. Then, based on the amount of movement of the winding roller extracted from the correction information, the movement unit 1f is instructed to move, and the winding roller 1a is moved. Thus, since the position of the winding roller 1a has moved to the left with respect to the conveyance path and the entrance / exit 1g, the paper 22 moves into the centering area of the entrance / exit 1g and is discharged.

  As described above, according to the paper sheet processing apparatus 1, the position of the paper sheet is detected during storage to calculate the amount of movement of the winding roller, and the winding roller 1a is adjusted in accordance with the amount of movement of the winding roller during discharge. Move to place the paper discharge position in the centering area. Accordingly, it is possible to suppress variations in the position of the paper sheets when discharged from the paper sheet processing apparatus 1 without providing a dedicated centering mechanism. In addition, since a dedicated centering mechanism is not required, the paper sheet processing apparatus can be reduced in size and cost.

Hereinafter, an example in which the embodiment is applied to a banknote temporary storage device built in an ATM will be described in detail with reference to the drawings.
Drawing 3 is a sectional view showing the example of composition of the bill temporary storage device of an embodiment.

  The banknote temporary storage device 10 controls the operation of the entire apparatus, the temporary stacker 200 that temporarily stores banknotes in a film, the transport unit that transports banknotes, and the movement that moves the temporary stacker 200. And a mechanism portion.

  The control unit 100 controls the operation of the entire apparatus. In accordance with signals from various sensors installed in the apparatus and instructions from an operator (not shown), operation control of various rollers in the apparatus is performed, and position control for controlling the position of the temporary stacker 200 is performed. Details will be described later.

  The temporary stacker 200 has a banknote winding roller 210 and winding film rollers 220a and 220b. At the time of banknote storage, the winding film rollers 220a and 220b rotate in the direction of pulling out the films 230a and 230b, respectively, and the banknote winding roller 210 rotates in the direction of winding up the film 230 on which the films 230a and 230b overlap. In the temporary stacker 200, the banknotes conveyed through the conveyance path 310 are sandwiched between the take-up film roller 220a and the films 230a and 230b drawn from the take-up film roller 220b. And a pair of film 230 which pinched | interposed the banknote is wound up by the banknote winding roller 210. FIG. Thus, the taken banknote is stored in the banknote winding roller 210. At the time of discharge, the banknote take-up roller 210, the take-up film roller 220a, and the take-up film roller 220b rotate in the reverse direction to move the film 230 sandwiching the banknote toward the transport path 310. The film 230 sandwiching the banknote moves toward the conveyance path 310, is divided into a film 230 a and a film 230 b, and discharges the banknote to the conveyance path 310. The temporary stacker 200 is installed on a moving rail 410 that extends in the same direction as the width direction of the banknote winding roller 210, and moves along the moving rail 410 by a moving mechanism unit.

  The transport unit includes a transport path 310, rollers 320a and 320b, a bill position detection sensor 330, and an entrance / exit sensor 340. The banknotes inserted from the outer end of the transport path 310 are transported in the storing direction on the transport path 310 by the rollers 320a and 320b. The banknote position detection sensor 330 provided in the middle of the transport path 310 detects the position of the banknote winding roller 210 in the width direction of the banknote passing therethrough and notifies the control unit 100 of it. The entrance / exit sensor 340 detects a bill that has reached the temporary stacker 200 and notifies the control unit 100 of it. At the time of discharge, the rollers 320a and 320b rotate in the reverse direction, and the bill moves from the temporary stacker 200 toward the outside of the apparatus along the conveyance path 310.

  The moving mechanism unit includes a moving rail 410, a motor 420, a belt 430, and a stacker position detection sensor 440. Details will be described in the following drawings. FIG. 4 is a top view of the bill temporary storage device shown in FIG. 3. The same components as those in FIG.

  The moving rail 410 extends in the width direction of the banknote winding roller 210 and is installed in the moving range of the temporary stacker 200. The motor 420 moves the belt 430 in the moving direction (width direction of the banknote winding roller 210) shown in FIG. The belt 430 is connected to the temporary stacker 200. When the belt 430 is moved by the motor 420, the temporary stacker 200 is moved in the moving direction. The stacker position detection sensor 440 detects the center position of the temporary stacker 200. Then, a deviation amount from the original state where the center of the temporary stacker 200 coincides with the center of the stacker position detection sensor 440 is detected. The detected deviation amount is notified to the control unit 100. In addition, the structure of a moving mechanism part is not limited to the structure shown in FIG.3 and FIG.4. For example, a rack mechanism or a link may be used as a means for moving the temporary stacker 200 in the moving direction. Further, a solenoid can be used as the driving means instead of the motor.

FIG. 5 is a block diagram illustrating a hardware configuration of a control unit of the temporary bill storage device.
The control unit 100 controls the entire apparatus by a CPU (Central Processing Unit) 101. A random access memory (RAM) 102, a hard disk drive (HDD) 103, an input interface 104, and a motor control unit 105 are connected to the CPU 101 via a bus 106.

  The RAM 102 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the CPU 101. The RAM 102 stores various data necessary for processing by the CPU 101. The HDD 103 stores the OS and application programs. A bill position detection sensor 330 and a stacker position detection sensor 440 are connected to the input interface 104, and signals sent from the bill position detection sensor 330 and the stacker position detection sensor 440 are transmitted to the CPU 101 via the bus 106. To do. The motor control unit 105 is connected to the motor 420, drives the motor 420, and moves the belt 430 (not shown).

With such a hardware configuration, the processing function of the information device can be realized.
FIG. 6 is a block diagram illustrating a software configuration of the control unit of the bill temporary storage device.
The control unit 100 includes a correction amount selection unit 110, a protrusion amount calculation unit 120, a correction amount calculation unit 130, a position control unit 140, a storage / release control unit 150, and a correction information storage unit 160. Each processing unit realizes its processing function by the CPU 101 executing the banknote processing program.

  The correction amount selection unit 110 selects the correction amount calculated by the correction amount calculation unit 130 at startup. The correction amount includes a first correction amount for the purpose of centering the banknote in the centering area and a second correction amount for the purpose of centering the banknote at the center of the centering area (the center of the conveyance path). There is. The second correction amount can improve the ease of taking out the released banknotes, for example, when the sizes of the banknotes to be handled vary. However, the movement amount of the temporary stacker 200 tends to be larger than the first correction amount. The temporary stacker 200 is moved from the time when a banknote is drawn to the time when the next banknote is drawn, but the banknotes are fed one by one to the conveyance path 310, and the minimum interval (distance) between the banknotes is set in advance. It has been decided. Therefore, the payout time until the next bill is paid based on the bill payout interval is compared with the maximum time required for the temporary stacker 200 to move. Then, when the movement of the maximum distance of the temporary stacker 200 is completed within the feeding time, the second correction amount is selected. The correction amount calculation method once selected is held until the operating condition of the apparatus changes. Note that the correction amount to be used may be selected by the user and instructed to the bill temporary storage device 10. The correction amount selection unit 110 notifies the correction amount calculation unit 130 of the application of the correction amount selected according to the instruction.

  The protruding amount calculation unit 120 compares the position in the width direction of the banknote winding roller 210 of the banknote detected by the banknote position detection sensor 330 with the positions of both ends of the centering area, and calculates the amount of each protruding. In addition, the measurement result of the banknote position detection sensor 330 assumes that the position of the temporary stacker 200 is fixed in the initial state, that is, the original center position. A method for calculating the amount of protrusion will be described later. The detected amount of protrusion is associated with the bill storage order and registered in the correction information stored in the correction information storage unit 160.

  The correction amount calculation unit 130 calculates the centering correction amount and the temporary stacker movement amount using the protrusion amount calculated by the protrusion amount calculation unit 120, and registers the calculated amount in the correction information. The calculation is performed using one of the calculation methods selected by the correction amount selection unit 110: “centering banknotes in the centering area” or “centering banknotes in the center of the conveyance path”. The calculation method of the centering correction amount and the temporary stacker movement amount will be described later.

  When the banknotes stored in the temporary stacker 200 are released, the position control unit 140 reads the correction information from the correction information storage unit 160 and determines the position of the temporary stacker 200 based on the temporary stacker movement amount of the banknote to be released next. Control. Based on the position information of the temporary stacker 200 detected by the stacker position detection sensor 440, the motor 420 is driven from the current position of the temporary stacker 200 based on the temporary stacker movement amount registered in the correction information, and the belt 430 is moved.

  The storage / discharge control unit 150 determines whether the banknote temporary storage device 10 performs a banknote storage process or a discharge process, and activates another processing unit according to the determination result. When a banknote storage instruction by an operator or the like is detected, or when a banknote is transported to the banknote temporary storage device 10, the storage process is started. The banknote take-up roller 210 and the take-up film rollers 220a and 220b are rotated in the banknote storage direction, and the protrusion amount calculation unit 120 is activated. On the other hand, when the banknote discharge instruction by the operator or the like is detected, the position control unit 140 is activated and the banknote winding roller 210 and the winding film rollers 220a and 220b are rotated in the banknote discharging direction.

The correction information storage unit 160 stores correction information. Details of the correction information will be described later.
Next, operation | movement of the banknote temporary storage apparatus 10 is demonstrated. In the following description, it is assumed that each process is started upon receipt of a storage instruction and a discharge instruction. In addition, it is assumed that whether the bill is centered in the centering region or whether the bill is centered in the center of the centering region (conveyance path center) is selected in advance by the correction amount selection unit 110. Note that the size of the bill is always smaller than the width of the centering region.

  In the control unit 100, when the storage / release control unit 150 receives an instruction from an operator or a higher-order program, the control unit 100 determines whether the instruction is a banknote storage process or a discharge process. When the instruction is a storage instruction, the storage / release control unit 150 rotates the rollers 320a and 320b of the transport path 310 in the banknote storage direction. The banknote storing direction refers to a direction in which the films 230 a and 230 b are drawn from the winding film rollers 220 a and 220 b and wound up by the banknote winding roller 210. The inserted banknote moves in the storing direction toward the temporary stacker 200 on the conveyance path 310. The rotation may be started when it is detected that the banknote is fed out from the entrance / exit 1g of the banknote temporary storage device 10, the banknote position detection sensor 330, or the banknote slot. The banknote position detection sensor 330 detects the position of the banknote passing through and notifies the control unit 100 of it.

In the control unit 100, the protruding amount calculation unit 120 calculates the protruding amount of banknotes.
FIG. 7 is a diagram showing the amount of protrusion detected by the protrusion amount calculation unit. The same parts as those in FIGS. X1 represents the left end of the centering region w1, X2 represents the right end, and Xc represents the center position coordinate.

  Here, the amount of protrusion is the distance between the leftmost point of the banknote and the left end X1 of the centering region w1 in the left direction. Further, when the position of the leftmost point of the banknote is on the left side of the left end X1 of the centering area as the direction of the protrusion amount, it is set as the positive direction (+). Conversely, when it is on the right side (within the centering area) from the left end of the centering area, the negative direction (-) is assumed. Similarly, in the right direction, the distance between the rightmost point of the banknote and the right end X2 of the centering region w1 is defined as the amount of protrusion. Further, when the rightmost point of the banknote is on the right side of the right end of the centering area, the positive direction (+) is assumed, and when it is on the left side, the negative direction (−) is assumed. Therefore, when one of the bills protrudes outside the centering area, the direction of the amount of protrusion is represented by “+”. If it is within the centering area, the direction of the protrusion amount is represented by “−”.

  When stored, banknotes are taken into the banknote winding roller 210 in the order of banknotes p1, p2, p3, and p4. In the case of the banknote p1, based on the position detected by the banknote position detection sensor 330, in the left direction, the distance “a1” between the leftmost point of the banknote and the left end X1 of the centering area w1 is referred to as “−” in the centering area. The amount of protrusion is obtained. In the right direction, the distance “a2” between the rightmost point of the banknote and the right end X2 of the centering area w1 and the amount of protrusion “+” outside the centering area are obtained. Hereinafter, the amount of protrusion is combined with the size and direction of the amount of protrusion, and is expressed as “−a1” and “+ a2”.

  Similar to the bill p1, the protruding amount of the bill p2 is “−b1” in the left direction and “+ b2” in the right direction. It shows that the right direction protrudes from the centering area. The protruding amount of the banknote p3 is “+ c1” in the left direction and “−c2” in the right direction. It shows that the left direction protrudes beyond the centering region. The protruding amount of the banknote p4 is “−d1” in the left direction and “−d2” in the right direction. It shows that the bill p4 is within the centering area. The amount of protrusion calculated in this way is registered in the correction information in association with the banknote storage order.

Subsequently, the correction amount calculation unit 130 calculates the centering correction amount and the temporary stacker movement amount based on the protrusion amount calculated by the protrusion amount calculation unit 120.
When centering the banknote in the centering area, the banknote winding roller 210 may be shifted at least by the amount of the protruding amount in the direction opposite to the protruding direction when the banknote is released. Therefore, the correction amount calculation unit 130 determines that each banknote is a centering target when there is “+” in the protruding amount in any direction. As the centering correction amount, the amount of protrusion on the protruding side (the amount of protrusion whose direction is +) is set. Further, as the direction in which the temporary stacker 200 is moved, the left direction is “−”, the right direction is “+”, “+” when protruding from the left end X1 of the centering area w1, and protruding from the right end X2. "-" When For example, the bill p1 is “+ a2” in the right direction and protrudes outward from the right end X2 of the centering region w1, so that the centering correction amount is “a2” and the movement direction of the temporary stacker 200 is “−”. Based on the centering correction amount thus obtained and the moving direction of the temporary stacker 200, the temporary stacker movement amount is calculated. The temporary stacker movement amount is information indicating a moving direction and a distance in which the temporary stacker 200 is moved for centering. Specifically, it is set by adding the moving direction to the centering correction amount. In the case of the bill p1, the temporary stacker movement amount obtained by combining the centering correction amount “a2” and the movement direction “−” is “−a2”. This indicates that the temporary stacker 200 is “moved leftward from the center point by a distance a2” for centering the banknote p1.

  Similarly, for the banknote p2, since the right end X2 side of the centering area w1 protrudes, the centering correction amount is “b2”, the movement direction of the temporary stacker 200 is “−”, and the temporary stacker movement amount is “−b2”. . As for the bill p3, since the left end X1 side of the centering area w1 protrudes, the centering correction amount is “c1”, the movement direction of the temporary stacker 200 is “+”, and the movement amount of the temporary stacker is “+ c1”. Regarding the banknote p4, the amount of protrusion is both “−” and does not protrude from the centering region w1, so that it is not corrected. Therefore, the correction amount becomes zero.

  Next, the case where a banknote is centered on a conveyance path center is demonstrated. Since the entrance / exit 1g is located at the end of the transport path 310, if the center of the transport path 310 can be centered, the bill is discharged so that the center of the banknote becomes the center of the entrance / exit 1g.

  FIG. 8 is a diagram illustrating a case where the banknote is centered around the conveyance path. When centering a banknote in the center of the conveyance path 310, the size of the empty area in the right direction and the left direction in the centering area when the banknote is placed in the center may be the same. Here, the empty area when each banknote is stored in the centering area is the amount of the protrusion indicated by “+” from the empty area (area where no banknote exists) of the current centering area w1 indicated by “−”. This is the size after subtracting the area. In the example of the banknote p2 in FIG. 8, the empty area when the banknote p2 is in the centering area is calculated by calculating the amount of protrusion “b2” protruding outside the centering area w1 from the amount of protrusion “b1” protruding into the centering area. Subtracted value. In this case, since “+” and “−” are set according to the direction, they may be added together. For example, the absolute value of “−b1 + b2” obtained by adding “−b1” in the left direction and “+ b2” in the right direction becomes a free area. When centering is performed at the center of the conveyance path 310, in addition to the amount of protrusion on the protruding side (“b2” in the case of the bill p2), the distance from the end of the centering region is half of the empty region calculated above (the bill). In the case of p2, the temporary stacker 200 may be moved until | −b1 + b2 | / 2). The direction of movement of the temporary stacker 200 is opposite to the direction of the amount of protrusion, so that the amount of protrusion on the left end X1 side is “+”, and the amount of protrusion on the right end X2 side is “+”. In case of, it becomes “-”. In the example of the banknote p2, it becomes “−”. The moving direction of temporary stacker 200 is set to “−” for the left direction and “+” for the right direction, as in the case of centering into the centering area. As described above, in the case of the bill p2, the centering correction amount is “b2 + | −b1 + b2 | / 2”, and the temporary stacker moving direction is “−”. Further, a temporary stacker movement amount is calculated. The temporary stacker movement amount is “−b2− | −b1 + b2 | / 2” because it is the moving direction of the temporary stacker 200 and the centering correction amount from the center point.

  Similarly, the centering correction amount of the bill p1 is “a2 + | −a1 + a2 | / 2”, the temporary stacker movement direction is “−”, and the temporary stacker movement amount is “−a2− | −a1 + a2 | / 2)”. . The centering correction amount of the bill p3 is “c1 + | c1−c2 | / 2”, the temporary stacker movement direction is “+”, and the temporary stacker movement amount is “c1 + | c1−c2 | / 2)”.

  Note that for the bill p4, the amount of protrusion is both “−”, and the empty area is the absolute value of d1 and d2. The centering correction amount is “d1− | d1 + d2 | / 2”, the temporary stacker movement direction is “+”, and the temporary stacker movement amount is “d1− | d1 + d2 | / 2”. In addition, when the amount of protrusion is “−” in both directions, or when one is “−” and the other is “0”, it can be calculated in the same manner.

The centering correction amount, the temporary stacker movement direction, and the temporary stacker movement amount calculated in this way are registered in the correction information in association with the bill storage order.
FIG. 9 is a diagram showing correction information when centering in the centering area.

Have.

  The bill 1611 is identification information for identifying each bill. The storage order 1612 is a banknote storage order, and indicates the order of banknotes taken from the entrance / exit 1g. The release order 1613 is the order in which the banknotes are released, and is the reverse order of the storage order. The X1 line protrusion amount 1614 indicates the protrusion amount with respect to the left end X1 of the centering region w1 calculated by the protrusion amount calculation unit 120. The X2 ray protrusion amount 1615 is the protrusion amount with respect to the right end X2 of the centering region w1 calculated by the protrusion amount calculation unit 120. The centering correction amount 1616 is a centering correction amount calculated by the correction amount calculation unit 130. When centering in the centering area, the amount of protrusion on the side where the amount of protrusion is “+” is set. The temporary stacker movement amount 1617 is the movement amount of the temporary stacker 200 calculated by the correction amount calculation unit 130.

FIG. 10 is a diagram showing correction information when centering in the center of the conveyance path.
Correction information (centering in the center of the conveyance path) 1620 includes information items such as a bill 1621, a storage order 1622, a discharge order 1623, an X1 line protrusion amount 1624, an X2 line protrusion amount 1625, a centering correction amount 1626, and a temporary stacker movement amount 1627. Have.

  The bill 1621 is identification information for identifying each bill. The storing order 1622 is the order in which banknotes are stored, and indicates the order of banknotes taken from the entrance / exit 1g. The release order 1623 is the order in which the banknotes are released, and is the reverse order of the storage order. The X1 line protrusion amount 1624 indicates the protrusion amount with respect to the left end X1 of the centering region w1 calculated by the protrusion amount calculation unit 120. The X2 ray protrusion amount 1625 is the protrusion amount with respect to the right end X2 of the centering region w1 calculated by the protrusion amount calculation unit 120. The centering correction amount 1626 is the centering correction amount calculated by the correction amount calculation unit 130. The temporary stacker movement amount 1627 is the movement amount of the temporary stacker 200 calculated by the correction amount calculation unit 130.

When the banknote is released, correction information related to the banknote released by the position control unit 140 is read out and position control is performed.
FIG. 11 shows the position control process.

  The position control unit 140 moves the position of the temporary stacker 200 before discharging the banknote from the temporary stacker 200 to the transport path 310, and discharges the banknote to the centering region of the transport path 310. Hereinafter, a case where the centering area is designated to be centered will be described.

  The position control unit 140 reads the correction information 1610 and performs processing in the order of release 1613. For example, the banknote p4 in the discharge order “1” does not move because the value of the centering correction amount 1616 is “0”. The temporary stacker 200 discharges the bill p4 to the transport path 310 at the original center position. Since the bill p4 was in the centering region at the time of storage, it is discharged into the centering region of the transport path 310. The entrance / exit sensor 340 detects that the banknote p4 has been discharged to the transport path 310, and reads the correction information 1610 of the banknote p3 in the next discharge order “2”. For the bill p3, “+ c1” is set in the correction information 1610 as the temporary stacker movement amount 1617. The position control unit 140 instructs the motor 420 to drive the temporary stacker 200 to move “c1” in the “+” direction (right direction). Thereby, the banknote winding roller 210 moves together with the temporary stacker 200 by “c1” in the right direction. As a result, the banknote p3 is released in the state of being moved “c1” in the right direction with respect to the conveyance path 310, and is discharged into the centering region of the conveyance path 310. Thereafter, the temporary stacker movement amount 1617 is read in accordance with the release order, and the position of the temporary stacker 200 is controlled.

  Similarly, when centering the conveyance path, the correction information 1620 is read out, the temporary stacker movement amount 1627 is read out in the order of the discharge order 1623, and the temporary stacker 200 is moved before the banknotes are discharged.

  As described above, the temporary banknote storage device 10 stores the centering correction amount for each sheet and the storing order at the time of storing, and temporarily stores each sheet based on the temporary stacker movement amount from the data at the time of storing. The stacker 200 moves and discharges bills.

  Next, the process procedure of the banknote processing method by the banknote temporary storage apparatus 10 is demonstrated. When receiving the storage instruction or the discharge instruction, the storage / release control unit 150 of the control unit 100 starts the storage process or the discharge process according to the instruction. In the storage process, the storage process of storing the bills inserted into the bill temporary storage device 10 in the temporary stacker 200 is started. In addition, when receiving a banknote release instruction, the banknotes stored in the temporary stacker 200 are discharged from the temporary stacker 200 to another storage unit, such as a deposit / withdrawal unit or a fixed safe unit. The process at the time of banknote accommodation and the process at the time of banknote discharge | release are demonstrated in detail.

FIG. 12 is a flowchart showing a processing procedure for storing bills.
[Step S01] The storage / release control unit 150 starts storage processing, rotates the banknote winding roller 210 and the winding film rollers 220a and 220b in the temporary stacker 200 in the banknote winding direction, and starts storage processing. To do.

[Step S02] The protrusion amount calculation unit 120 acquires the position of the banknote detected by the banknote position detection sensor 330.
[Step S03] The protrusion amount calculation unit 120 calculates the protrusion amount of the banknote from the centering area based on the position of the banknote detected in step S02. The left end of the centering area is compared with the position of the leftmost point of the detected banknote in the traveling direction of the banknote, and the distance is defined as the amount of protrusion in the left direction. Similarly, the right end of the centering area is compared with the position of the rightmost point of the detected banknote, and the distance is set as the amount of protrusion in the right direction. The calculated amount of protrusion is stored in the correction information in association with the banknote storage order.

  [Step S04] The correction amount calculation unit 130 determines whether or not “centering in the centering area” is selected as the centering process. If “centering in the centering area” is selected, the process proceeds to step S05. If “centering in the center of the conveyance path” is selected, the process proceeds to step S06.

  [Step S05] When “centering in the centering area” is selected, the correction amount calculation unit 130 reads the amount of protrusion from the correction information, and indicates that the amount of protrusion of the bill protrudes outside the centering area. If this is the case, the amount of protrusion is taken as the centering correction amount. Then, the temporary stacker movement amount is calculated according to the procedure described in FIG. 7, and the process proceeds to step S07.

  [Step S06] When “centering in the center of the conveyance path” is selected, the correction amount calculation unit 130 calculates a free area of the centering region when centering is performed from the amount of protrusion, and sets it as the centering correction amount. Then, the temporary stacker movement direction and the temporary stacker movement amount are calculated according to the procedure described in FIG.

  [Step S07] The correction amount calculation unit 130 registers the centering correction amount and the temporary stacker movement amount calculated by the respective calculation methods in the correction information 1610 and 1620 in association with the banknote storage order.

  [Step S08] The storage / release control unit 150 determines whether there is an instruction to stop the storage process. If there is no cancel instruction, the process returns to step S02, and the next banknote is stored. When there is an instruction to cancel, the process ends.

  By executing the above processing procedure, when storing banknotes, the centering correction amount and the temporary stacker movement amount for centering each banknote in association with the storing order are registered.

FIG. 13 is a flowchart showing a processing procedure when a bill is released.
[Step S11] The storage / release control unit 150 rotates the banknote winding roller 210 and the winding film rollers 220a and 220b in the temporary stacker 200 in the banknote discharging direction, and starts the banknote discharging process.

  [Step S12] The position control unit 140 reads the correction information and determines whether there is a banknote stored. If there is a stored banknote, the process proceeds to step S13. When there is no bill stored, the process is terminated.

[Step S13] When there is a bill stored, the position control unit 140 reads the correction information of the latest stored bill, that is, the largest storage order.
[Step S14] The position control unit 140 extracts the temporary stacker movement amount from the read bill correction information.

[Step S15] The position control unit 140 controls the motor 420 based on the temporary stacker movement amount read in step S14 to move the temporary stacker 210.
[Step S <b> 16] After the position control unit 140 detects that the banknote has been discharged to the transport path 310 by the entrance / exit sensor 340, it registers and deletes the correction information of the target banknote.

  [Step S17] The position control unit 140 determines whether there is an instruction to stop the discharge. When the stop instruction is received, the process is terminated. When the cancel instruction has not been received, the process returns to step S12 to perform the next bill release process.

  By executing the above processing procedure, when the banknote is released, the position of the temporary stacker 200 moves so that the banknote is released into the centering area based on the correction information set when the banknote is stored. Is done.

  In the above description, the correction amount calculation unit 130 sets the temporary stacker movement direction and the temporary stacker movement amount related to the movement of the temporary stacker 200 together with the centering correction amount. However, the movement amount calculation of the temporary stacker 200 is performed by the position control unit. 140 may be performed.

  Further, the temporary stacker 200 may be moved not at the time of banknote release but at the time of storage. In this case, the position control unit 140 moves the temporary stacker 200 before sandwiching the banknote between the films based on the temporary stacker movement direction and the temporary stacker movement amount calculated by the correction amount calculation unit 130.

FIG. 14 is a diagram illustrating a case where centering is performed during bill storage.
The banknote position detection sensor 330 detects the position of the banknote p2, and the protrusion amount calculation unit 120 calculates the protrusion amount “−b1” in the left direction and the protrusion amount “+ b2” in the right direction. The amount of protrusion is calculated in the same manner as the protrusion amount calculation processing procedure described with reference to FIG.

  Next, the correction amount calculation unit 130 calculates the centering correction amount. Here, a case where centering is performed in the centering area will be described. The correction amount calculation unit 130 calculates the rightward protrusion amount “+ b2” that protrudes from the centering region w1 as the centering correction amount. The temporary stacker movement amount is the same as the centering correction amount in the movement amount, but the temporary stacker movement direction is opposite to the case where the position control of the temporary stacker 200 is performed at the time of release. That is, in order to wind the banknote p2 within the centering region of the banknote winding roller 210, the banknote winding roller 210 must be moved to the right. Therefore, the temporary stacker movement amount is “+ b2”, and the temporary stacker 200 is moved rightward by a distance of “b2”. In this state, the banknote p2 is stored in the centering region of the banknote winding roller 210 by winding the banknote p2. When the position of the temporary stacker 200 is controlled during storage, the position of the temporary stacker 200 during discharge is fixed at the center.

FIG. 15 is a flowchart showing a processing procedure when centering is performed during bill storage.
[Step S <b> 21] The storage / release control unit 150 determines whether to perform storage processing or discharge processing. If it is determined that the storage process, the process proceeds to step S22. If it is determined that the release process is to be performed, the process proceeds to step S28.

  [Step S22] When it is a storage process, the storage / release control unit 150 starts the storage process, rotates the banknote winding roller 210 and the winding film rollers 220a and 220b in the storage direction, and stores the banknote temporary storage apparatus 10. It is determined whether or not a bill has been inserted. When it is detected that a bill has been inserted, the protrusion amount calculation unit 120 is activated, and the process proceeds to step S23. When the insertion of the banknote is not detected, the process returns to step S21 to perform processing from confirmation of the instruction.

[Step S <b> 23] When the insertion of a banknote is detected, the protrusion amount calculation unit 120 acquires the position of the banknote detected by the banknote position detection sensor 330.
[Step S24] The protrusion amount calculation unit 120 calculates the protrusion amount of the banknote from the centering region based on the position of the banknote detected in step S23. The left end of the centering area is compared with the position of the leftmost point of the detected banknote in the traveling direction of the banknote, and the distance is defined as the amount of protrusion in the left direction. Similarly, the right end of the centering area is compared with the position of the rightmost point of the detected banknote, and the distance is set as the amount of protrusion in the right direction. The calculated amount of protrusion is stored in the correction information in association with the banknote storage order.

  [Step S25] The correction amount calculation unit 130 calculates a centering correction amount based on the protrusion amount calculated in step S24. Then, based on the centering correction amount, the temporary stacker movement direction and the temporary stacker movement amount are calculated. The calculation method of the centering correction amount and the temporary stacker movement amount is the same as the storage process shown in FIG. The temporary stacker moving direction is opposite to the storing process shown in FIG. That is, the temporary stacker movement direction when the banknote to be stored protrudes outside the right end of the centering region is the right direction, and the temporary stacker movement direction when protruding outside the left end is the left direction.

[Step S26] The position controller 140 moves the temporary stacker 200 based on the temporary stacker movement amount calculated in step S25.
[Step S27] The storage / release control unit 150 performs banknote storage processing. The temporary stacker movement amount is registered in the correction information 1610 and 1620 in association with the bill storage order. The entrance / exit sensor 340 confirms that the banknote has been sandwiched between the films 230, and the process returns to step S21.

  [Step S <b> 28] When it is a release process, the storage / release control unit 150 reads the correction information 1610 and 1620 and determines whether there is a stored banknote. If there is a bill, the process proceeds to step S29. When there is no banknote, the process returns to step S21 to perform processing from confirmation of the instruction.

  [Step S29] The storage / release control unit 150 releases the bills of the correction information 1610 and 1620. The position of the temporary stacker 200 at this time is fixed at the center. And when it detects that the banknote was discharge | released by the entrance / exit sensor 340, registration of an applicable banknote is deleted from the correction information 1610,1620.

  By executing the above processing procedure, the temporary stacker 200 is moved during storage to center the banknote, and the banknote is stored in the centering area of the banknote winding roller 210. When released, it is released as it is.
