Description

  The present invention relates to a paper sheet feeding device and a control method thereof, and in particular, separates and feeds a bundle of paper sheets loaded in a state where a plurality of paper sheets such as banknotes are stacked one by one. The present invention relates to a paper sheet feeding device and a control method thereof.

  Some banknote deposit processing apparatuses that accept banknote deposits, such as an automated teller machine, can insert a plurality of banknotes up to a predetermined number. Such a banknote depositing processing apparatus includes a paper sheet feeding device that separates and feeds banknotes inserted in bundles one by one from the necessity of performing discrimination of the deposited banknotes one by one. ing.

  The paper sheet feeding device separates the inserted banknotes one by one from the bundle of banknotes inserted, and sequentially feeds the separated banknotes to the conveyance path to the deposit discrimination unit. Here, when the banknote bundle is inserted in a state inclined with respect to the input direction, the separated banknotes are also fed out while being inclined. If the separated banknotes are sent to the transport path in a tilted state, it may cause a paper jam on the transport path or stop the banknote deposit processing device, and the deposit discrimination part may remain tilted. Since the banknotes are discriminated in the state, the acceptance rate of the banknotes is lowered due to, for example, a reduction in the discrimination accuracy.

On the other hand, even when the banknote bundle is inserted in a tilted state, a technique for controlling the tilted banknote to be corrected is known (see, for example, Patent Document 1). This Patent Document 1 relates to a paper sheet take-out device that separates and takes out stacked banknotes one by one, and can prevent oblique feeding (skew). In order to prevent skew, the paper sheet take-out device is equipped with a limit switch that detects skew, and when the limit switch detects skew, it is juxtaposed perpendicular to the take-out direction to separate banknotes. By variably controlling their torques with respect to the two reversing rollers, the posture is controlled while taking out the inclined banknote.

  However, in the conventional paper sheet take-out device, in order to prevent skew, a limit switch for detecting skew and a means for variably controlling the torque with respect to the pair of reverse rotation rollers are necessary, and the configuration becomes complicated and the cost is reduced. There was a problem that became high.

  The present invention has been made in view of the above points, and is a paper sheet feeding device capable of controlling the skew posture of a loaded paper sheet bundle without any additional change in the mechanism for realizing the feeding function. And it aims at providing the control method.

In the present invention, in order to solve the above-described problem, the one-way is arranged so as to be spaced apart in a direction perpendicular to the feeding direction so as to contact the lower surface of the bundle of paper sheets fed to the feeding slot, and to idle and rotate only in the feeding direction. A clutch is built in, and a pair of first feeding rollers for feeding the sheet bundle in the feeding direction by rotational driving in the feeding direction, and the sheet bundle can be pressed against the first feeding roller. The placement assist solenoid disposed and the sheet bundle bundle disposed at the front edge of the sheet bundle in a direction perpendicular to the feeding direction and arranged side by side, and sent by the first feeding roller. A pair of second feeding rollers for feeding the lowest-level paper sheets in the feeding direction and a one-way clutch are arranged so as to be in pressure contact with the second feeding roller so as not to rotate in the feeding direction. A pair of separation rollers for separating the lowest sheet from the bundle of sheets fed by the first feeding roller in cooperation with the second feeding roller; A paper sheet feeding device that includes a feeding roller and a feeding motor that rotationally drives the second feeding roller, and separates and feeds the paper sheets one by one from the fed paper sheet bundle; Before starting the operation of separating and feeding out the leaf bundle one by one, the feeding motor is rotated forward in the feeding direction for a predetermined time to take in the sheet bundle in the feeding direction, and then the feeding motor is turned on. by the feeding direction driven in reverse in the reverse direction by a predetermined time, a control unit having a skew attitude control function of attitude control in the absence of inclination with respect to the paper sheet bundle having been put inclined, the control unit Is a bundle of paper sheets In response to the input detection, the skew posture control function is executed, and while the paper sheets are fed, the feeding auxiliary solenoid that operates to press the sheet bundle against the first feeding roller, Provided is a paper sheet feeding device having a running posture control function for temporarily energizing and deactivating the loading auxiliary solenoid before executing the skew posture control function .

  According to such a paper sheet feeding device, the control unit energizes the loading auxiliary solenoid before the feeding of the sheet bundle is detected and the separation / feeding operation of the sheet bundle is started. The pressed bill bundle is pressed against the first feeding roller, and then the feeding motor is controlled. First, the first feeding roller and the second feeding roller are driven to rotate forward in the feeding direction for a predetermined time. The second feeding roller and the separation roller take in the sheets in the feeding direction in the feeding direction, and then the second feeding roller is driven reversely for a predetermined time to be between the second feeding roller and the separation roller. The paper sheet taken in the pressure contact portion is sent out in the direction opposite to the feeding direction. As a result, if the fed sheet bundle is tilted, one of the pair of second feeding rollers will first exit the clamping state with the separation roller. At this point, the second feeding roller located on the opposite side is still feeding the sheet bundle in the direction opposite to the feeding direction together with the separation roller, and is loaded on the side that has previously passed the second feeding roller. Since the auxiliary solenoid presses the sheet bundle against the first feeding roller, the sheet is rotated around the pressed point and the posture is controlled so as not to tilt.

The paper sheet feeding apparatus according to the present invention is a paper sheet bundle that is fed prior to the bill feeding operation without changing the configuration of the first feeding roller, the loading auxiliary solenoid, the second feeding roller, and the separation roller. The first feeding roller and the second feeding roller are normally driven in the feeding direction for a predetermined time while the second feeding roller is reversely driven for a predetermined time. Therefore, it is possible to control the skew posture, so that there is no need for a means for detecting skew and a means for controlling the posture to have no inclination in response to the detection of the skew. There is an advantage that it is possible to prevent a decrease in the acceptance rate.

  Further, the paper sheet feeding device according to the present invention, when receiving a feeding request instruction from the host control device, merely activates the charging auxiliary solenoid once to de-energize the paper sheet. Even when the vehicle is thrown on the side wall, it is possible to cancel the riding state.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, taking as an example a case where the present invention is applied to a banknote deposit processing apparatus.

The withdrawal port 8 and the collection box 9 are connected to the downstream side of the deposit discrimination unit 3 via a conveyance path.

  In the banknote deposit processing apparatus having the above configuration, when a bundle of banknotes is inserted into the insertion slot 1, the bundle of banknotes is separated and fed out one by one by the paper sheet feeding device 2. The fed banknotes are discriminated by the deposit discriminating section 3, and the discriminated banknotes are transported and stored in the safes 4 and 5 corresponding to the denomination if they are true coins. It is conveyed to the gate 8 and returned. In addition, this banknote payment processing apparatus can be functioned also as a banknote payment processing apparatus. In that case, the banknote of the denomination to be withdrawn is drawn out from the safes 4 and 5 and discriminated by the withdrawal discriminating unit 7, and the banknote discriminated as possible to be withdrawn is conveyed to the withdrawal port 8 and taken out. The banknotes that have been identified as being non-withdrawable are transported to the scrutiny 6 and stored.

FIG. 2 is a diagram showing the configuration of the paper sheet feeding device according to the present invention.
This paper sheet feeding device has a feeding roller 11 so as to abut a lower surface of a stack of banknotes 10 placed on a lower part of a banknote placement surface on which a bundle of banknotes 10 inserted into the slot 1 is placed. Is arranged. Two feeding rollers 11 are provided apart from each other in a direction orthogonal to the feeding direction. Further, although not shown in the drawing, this feeding roller 11 has a built-in one-way clutch so that it can idle and rotate only in the feeding direction.

  A charging auxiliary solenoid 12 that can freely come into contact with and separate from the feeding roller 11 is disposed above the charging port 1. When the banknote 10 is inserted, the insertion assist solenoid 12 presses the bundle of banknotes 10 against the feeding roller 11 to help the banknote 10 being fed out by the feeding roller 11.

  At the leading edge of the insertion position of the banknote 10 which is the innermost part of the insertion slot 1, a feeding roller 13 is disposed below the banknote placement surface. A separation roller 14 is disposed on the top of the banknote placement surface, and is in pressure contact with the feeding roller 13 so as to dam the bundle of banknotes 10 inserted together with the feeding roller 13. The separation roller 14 has a built-in one-way clutch that rotates in a direction opposite to the feeding direction but does not rotate in the feeding direction. Two of these feeding rollers 13 and separation rollers 14 are also provided apart from each other in the width direction orthogonal to the feeding direction, and the lowest banknote 10 is removed from the bundle of banknotes 10 fed by the feeding roller 11. It has a function of separating only one sheet and feeding it in the feeding direction.

  Between the feeding roller 11 and the feeding roller 13, a closing detection sensor 15 is disposed. The insertion detection sensor 15 is an optical sensor that detects the insertion of the banknote 10 when the optical axis is blocked by the inserted banknote 10.

  On the feeding side of the feeding roller 13, a conveying roller 16 that receives the fed banknote and sends it to the downstream side is disposed. Two transport rollers 16 are also provided apart from each other in the width direction orthogonal to the bill feeding direction.

  On the delivery side of the transport roller 16, an optical deposit preparation sensor 17 that detects the passage of the fed banknote and a transport roller 18 that transports the fed banknote to the deposit discrimination unit 3 are arranged.

  Here, the feeding rollers 11 and 13 and the conveying roller 16 are rotationally driven by a feeding motor 19, and the conveying roller 18 is rotationally driven by a conveying motor 20. The paper sheet feeding device includes a control unit 21 that controls the paper feeding device. The control unit 21 is connected to a loading detection sensor 15, a deposit preparation sensor 17, a feeding motor 19, and a conveyance motor 20. Yes. The control unit 21 is further connected to a host control device 22 that controls the entire banknote deposit processing apparatus. Next, a hardware configuration example of the control unit 21 will be described.

FIG. 3 is a block diagram illustrating a configuration example of a control unit of the paper sheet feeding device.
The control unit 21 includes a central processing unit (CPU: Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, and an interface unit (I / F) 34. Are connected to each other. Further, the control unit 21 includes a drive circuit 36 for driving the feeding motor 19, a drive circuit 37 for driving the carry motor 20, and a drive circuit 38 for driving the auxiliary charging solenoid 12. These drive circuits 36, 37, 38 are Are connected to the interface unit 34. The interface unit 34 is connected to receive detection output signals from the insertion detection sensor 15 and the deposit preparation sensor 17, and is further connected to the host controller 22.

  The ROM 32 stores basic software to be executed by the CPU 31, a program for controlling the paper sheet feeding device in cooperation with the host control device 22, a program for realizing functions of skew posture control and riding posture control described later, and the like. Yes.

  The RAM 33 temporarily stores at least a part of basic software and programs loaded from the ROM 32, and temporarily stores various data related to processing by the CPU 31. With the hardware configuration described above, the paper sheet feeding device can realize the processing functions of skew posture control and riding posture control. Next, a processing example between the control unit 21 and the host control device 22 will be described.

FIG. 4 is a flowchart showing a first processing example of the control unit of the higher order control device of the banknote deposit processing device and the paper sheet feeding device.
Here, the processing flow of the host control device 22 of the banknote depositing processing device and the control unit 21 of the paper sheet feeding device 2 will be described, but the processing of the host control device 22 is related to the paper sheet feeding device 2. Only processing is shown.

  The processing of the host controller 22 is started when an event of banknote deposit processing occurs in the banknote deposit processor, and the host controller 22 first receives the bill insertion detection information from the control unit 21 of the paper sheet feeding device 2. It is determined whether there is a notification (step S1). If there is no notification of bill insertion detection information from the control unit 21, the host control device 22 waits until it receives notification of insertion detection information.

  Here, when the notification of the insertion detection information of the banknote 10 is received from the control unit 21, the upper control device 22 confirms the insertion detection of the banknote and feeds the banknote toward the control unit 21 of the paper sheet feeding device 2. A request instruction is issued, and the process is terminated (step S2).

Next, a processing example of the control unit 21 of the paper sheet feeding device 2 that operates in cooperation with the host control device 22 of the banknote deposit processing device will be described.
The processing of the control unit 21 is started when an event of banknote depositing processing occurs in the banknote depositing processing device. When the insertion detecting sensor 15 detects the insertion of the banknote 10 into the slot 1, the upper control device 22 is notified of input detection information (step S11).

After the notification of the insertion detection information, the control unit 21 stands by until an instruction for a bill feeding request is received from the host control device 22 (step S12).
Here, when an instruction for a bill feeding request is received from the host control device 22, the control unit 21 executes skew posture control described later (step S13). This skew posture control is performed every time the control unit 21 receives a bill feeding request instruction from the host control device 22 regardless of whether or not the inserted bill 10 is actually skewed.

  When the skew posture control is completed, the control unit 21 activates the conveyance motor 20 and rotates the conveyance roller 18 prior to starting the feeding operation by the paper sheet feeding device 2, so that the bill can be conveyed in advance on the conveyance path. The state is set (step S14).

  Next, the control unit 21 starts the feeding motor 19 and rotationally drives the feeding rollers 11 and 13 and the conveying roller 16 in the feeding direction to start a bill feeding operation (step S15). In this bill feeding operation, the feeding roller 11 performs an operation of feeding the bill 10 into the contact portion between the feeding roller 13 and the separation roller 14, and the feeding roller 13 that is driven to rotate and the separation roller 14 that does not rotate have these frictional forces. The bills 10 at the bottom of the bundle are separated and fed one by one. The fed banknote 10 is delivered to the transport roller 16, and the transport roller 16 transports it to the transport roller 18 disposed on the downstream side thereof. A deposit preparation sensor 17 is disposed in front of the transport roller 18, and the deposit preparation sensor 17 detects passage of the banknote 10 transported to the transport roller 18 by the transport roller 16. After the banknote 10 passes through the deposit preparation sensor 17 and reaches the position of the transport roller 18, the control unit 21 stops the feeding motor 19. At this time, the banknote 10 that has reached the transport roller 18 is transported to the deposit discrimination unit 3 by the transport roller 18.

  Next, the control part 21 judges whether the banknote 10 remains in the insertion slot 1 (step S16). If the banknote 10 remains in the insertion slot 1, it will return to step S15 and the control part 21 will restart banknote feeding operation | movement.

  In step S <b> 16, when it is determined that no bill remains in the insertion slot 1, the control unit 21 stops the conveyance motor 20, stops the conveyance roller 18, and moves the insertion auxiliary solenoid 12 away from the feeding roller 11. And the bill feeding process is terminated (step S17).

Next, the skew posture control process in step S13 will be described.
FIG. 5 is a flowchart showing a flow of processing of skew posture control.
The skew posture control process is started when the control unit 21 receives a bill feeding request instruction from the host control device 22. First, the control unit 21 urges the insertion assist solenoid 12 to pressurize the bundle of banknotes 10 in a direction in which the bundle is pushed against the feeding roller 11 (step S21).

  Next, the control unit 21 rotates the feeding motor 19 in the normal direction to rotate the feeding roller 11 and the feeding roller 13 in the feeding direction, and separates the banknote 10 by feeding it in the feeding direction while keeping the posture at the time of insertion. Then, it is taken into the pressure contact portion between the feeding roller 13 and the separation roller 14 (step S22). At this time, the control unit 21 starts a timer simultaneously with the start of normal rotation driving of the feeding motor 19.

  It is determined whether or not the timer activated in step S22 has timed out. If the timer has not timed out, the control unit 21 waits until time out (step S23).

  After rotating the feeding roller 11 and the feeding roller 13 in the feeding direction for a predetermined time, the control unit 21 stops the feeding motor 19 and stops the rotation of the feeding roller 11 and the feeding roller 13 (step S24).

  Thereafter, the control unit 21 performs control so that the feeding motor 19 is driven in reverse rotation, and starts the timer simultaneously with the start of reverse rotation driving (step S25). At this time, since the feeding roller 11 does not rotate, the holding state of the banknote 10 is maintained together with the insertion assisting solenoid 12, and only the feeding roller 13 sends out the banknote 10 together with the separation roller 14 in the direction opposite to the feeding direction. Become.

  It is determined whether or not the timer activated in step S25 has timed out. If the timer has not timed out, the control unit 21 waits until time out (step S26).

  After the feeding roller 13 is driven in reverse rotation in the direction opposite to the feeding direction for a predetermined time, the control unit 21 stops the feeding motor 19 and stops the feeding roller 13, and the skew posture control process is completed. The process returns to (step S27).

  Next, a description will be given of a mechanism in which the banknote 10 inserted while being tilted with respect to the feeding direction is controlled so as to correct the posture to a posture without tilting by the above skew posture control processing.

  6 is an explanatory diagram showing the first step of the skew posture control, FIG. 7 is an explanatory diagram showing the first half of the second step of the skew posture control, and FIG. 8 is an explanatory diagram showing the second half of the second step of the skew posture control. 9 is an explanatory diagram showing a state of completion of the skew posture control, and FIG. 10 is an explanatory diagram showing a posture transition state of the banknote by the skew posture control.

  These explanatory views are views of the paper sheet feeding device 2 as viewed from above. Here, it is assumed that the banknote 10 is inserted in the short direction, and in the banknote insertion direction, the feeding roller 11, the insertion detection sensor 15, the feeding roller 13, the transport roller 16, the deposit preparation sensor 17, and the transport roller 18 are provided. Each is arranged in pairs.

  Now, when the banknote 10 is thrown in, as shown in FIG. 6, suppose that the left side of the banknote inclined forward. In the first step of skew posture control, after the insertion assist solenoid 12 presses the bill 10 against the feeding roller 11, the feeding rollers 11, 13 and the transport roller 16 rotate in the feeding direction, and the bill 10 is fed in the bill insertion direction. put out. Thereby, the banknote 10 is taken in between the feeding roller 13 and the separation roller 14 in an inclined posture.

  In the next step of the skew attitude control, first, the taken banknote 10 is returned to the direction opposite to the banknote insertion direction with the tilted attitude as shown in FIG. . At this time, when the banknote 10 is on it, the feeding roller 13 gives the banknote 10 a force to be conveyed in the reverse direction. However, at the part of the feeding roller 11, the banknote 10 is fed with the feeding roller 11, the insertion auxiliary solenoid 12, and the like. And acts to block the force of conveying the banknote 10 in the reverse direction. Since the conveying force of the feeding roller 13 is set to be larger than the blocking force of the feeding roller 11, the banknote 10 is returned in the direction opposite to the banknote insertion direction while being tilted.

  If the banknote 10 is returned in the reverse direction while being tilted, the banknote 10 will eventually pass through the right side of the feeding roller 13 as shown in FIG. Since the conveying force applied to the banknote 10 is lost on the side that has been removed, when the conveying force is applied to the banknote 10 by the feeding roller 13 on the side that has not been removed (left side in the figure), the banknote 10 is Rotates with a point sandwiched between the feeding roller 11 and the closing auxiliary solenoid 12 on the side that has passed through (right side in the figure) as a fulcrum. This rotation is until the banknote 10 passes through the feeding roller 13 on the left side of the drawing and the conveying force is lost. Thus, as shown in FIG. It will stop at the position where it has come off, and it will be controlled to a posture with no inclination.

  The manner in which the above banknote 10 rotates is summarized as shown in FIG. That is, in the process in which the banknote 10 is returned in the direction opposite to the banknote insertion direction, first, when the banknote 10 passes through the right feeding roller 13 (state a), this time, only the conveying force of the left feeding roller 13 is reversed. Back in the direction. At this time, the banknote 10 is sandwiched between the right feeding roller 11 and the auxiliary charging solenoid 12, but since there is no conveying force by the right feeding roller 13, it is counterclockwise around the sandwiched point α. (State b). This rotation stops when the banknote 10 passes through the left feeding roller 13, the front edge of the banknote 10 comes to the position where it passes through the left and right feeding rollers 13, and the banknote 10 is not tilted. Controlled (state c). In the illustrated example, such skew posture control is rotated in the counterclockwise direction. However, when the tilt direction is reversed, the banknote 10 is rotated in the clockwise direction so that there is no tilt posture control. Is done. Thereby, the banknote deposit processing apparatus does not decrease the acceptance rate of banknotes.

  By the way, when a bundle of banknotes is inserted into the insertion slot 1, even if the banknotes 10 are inserted straight without inclination, the banknotes 10 may be inserted in a state where the banknotes 10 run on either the left or right side wall of the insertion slot 1. Even in such a case, it may become a factor of the acceptance rate reduction of a banknote.

12A and 12B are explanatory views showing a state in which one end of a bundle of banknotes rides on the side wall of the insertion slot. FIG. 12A is a view seen from above, and FIG.
When the banknote 10 is inserted into the insertion slot 1 in a state of being biased in the lateral direction (left direction in the illustrated example), the banknote 10 may run on the side wall of the insertion slot 1. Even in such a case, the paper sheet feeding device 2 is fed while remaining on the side wall, and this also causes a decrease in the acceptance rate of the banknotes 10 as in the case of oblique feeding. ing. Next, a description will be given of the riding posture control that copes with the bill insertion in such a riding state.

  FIG. 11 is a flowchart showing a second processing example of the host control unit of the banknote deposit processing apparatus and the control unit of the paper sheet feeding apparatus. In FIG. 11, the processing on the host control device 22 side is the same as that shown in FIG.

  First, when the insertion detection sensor 15 detects the insertion of the banknote 10 into the insertion slot 1, the control unit 21 notifies the upper control device 22 of the insertion detection information (step S <b> 31), and issues a bill feeding request from the upper control device 22. Wait for an instruction (step S32).

  When receiving an instruction for bill feeding request from the host control device 22, the control unit 21 executes the riding posture control (step S33). The riding posture control is performed by using a loading auxiliary solenoid 12 that sandwiches the banknote 10 together with the feeding roller 11 when the banknote 10 is fed out. The operation mechanism will be described later.

  After executing this riding posture control, the control unit 21 executes skew posture control (step S34), activates the carry motor 20, and rotates the carry roller 18 to make it ready for carrying (step S35).

  Next, the control unit 21 repeats the bill feeding operation of starting the feeding motor 19, separating and feeding the bill 10, and stopping the feeding motor 19 (step S <b> 36) until the bill 10 is removed from the insertion slot 1. Execute (Step S37). When the bill 10 is exhausted from the insertion slot 1, the control unit 21 stops the transport motor 20, controls the insertion auxiliary solenoid 12 in the direction away from the feeding roller 11, and ends the bill feeding process (step S38). ).

  FIG. 13 is an explanatory diagram showing a banknote posture transition state by the riding posture control, where (A) is an explanatory diagram showing a first step of the riding posture control, and (B) is an explanation showing a second step of the riding posture control. FIG. 4C is an explanatory diagram showing a state in which the riding posture control is completed.

  First, when the banknote 10 is inserted into the insertion slot 1 in a state of being biased to the left in the illustrated example, and the left end of the banknote 10 rides on the left side wall of the insertion slot 1, the riding posture control of the control unit 21 is As the first step, as shown in FIG. 13A, the insertion assist solenoid 12 is urged to press the bill 10 against the feeding roller 11 from above. Then, as shown in FIG. 13B, the control unit 21 deenergizes the making auxiliary solenoid 12 and raises the making auxiliary solenoid 12 in the direction away from the feeding roller 11 as the second step.

  Thus, by pushing down the insertion assist solenoid 12 once against the banknote 10 riding on the left side wall of the insertion slot 1, one end of the banknote 10 on the side of the insertion is bent, and then the insertion assist solenoid 12 is pushed up. Thus, the external force applied to the banknote 10 is released at once. As a result, a repulsive force is generated to return the bent-up portion of the banknote 10 to its original straight shape, and the entire banknote 10 is moved to the center of the insertion slot 1 by the repulsive force of the banknote 10 itself. As shown in (C) of FIG. In this way, even if the banknote 10 has been loaded, the banknote can be stably fed because the boarding state is canceled before the feeding operation is started. In addition, in the state of the normal insertion posture in which the banknote 10 is not climbed, this riding posture control has no effect on the banknote 10.
