Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a sheet processing apparatus for feeding out sheets such as banknotes one by one from a stacked state.

  Conventionally, as a bill processing apparatus for sending out bills one by one from a plurality of accumulated bills and identifying the bills, a bill processing apparatus provided with a batch loading device and an identification device as described in Patent Document 1 is disclosed. Are known.

  As shown in FIG. 13, the batch loading device 600 described in Patent Document 1 has a box shape comprising a lower housing 61a and an upper housing 61b openably and closably connected to the lower housing 61a via a hinge means 62. The housing 61 is provided. A bill receiving portion 60 is attached to the front side wall portion of the lower housing 61a, and from the bill receiving portion 60, a plurality of (for example, about 20) bills can be received into the housing 61. ing. Moreover, the bill delivery port 61c which sends out the banknote after isolation | separation to a downstream side is formed in the back surface side wall part of the lower housing 61a.

  In the housing 60, a guide plate 63 for guiding the accumulated bills PA, an accumulated bill taking-in roller 64 located above the guide plate 63, and a feed roller constituting a bill separating means on the downstream side of the accumulated bill taking-in roller 64. 65 and a return roller 66, and a delivery drive motor 67 as a drive source are provided.

  The accumulated bill take-in roller 64 is attached to the take-in roller shaft 64 a. The take-in roller shaft 64 a is rotatably supported by the pivotable roller link 68. Therefore, the stacked bill taking-in roller 64 can move up and down with the swing of the roller link 68. Further, a take-in roller gear 64b is provided on the take-in roller shaft 64a.

  The feed roller 65 is supported by a feed roller shaft 65a via a one-way clutch (not shown). The feed roller shaft 65a is connected to the feeding drive motor 67 via a transmission means (not shown). A feed roller gear 65b is provided on the feed roller shaft 65a. The feed roller 65 is rotatable with respect to the feed roller shaft 65a, and the projection 65c provided on the feed roller 65 engages with an arc groove 65d provided on the feed roller gear 65b, whereby the feed roller gear is provided. It is connected in a state where relative rotation is permitted by a predetermined rotation angle (the range of the arc groove) with respect to 65b.

  The feed roller gear 65 b and the take-in roller gear 64 b are connected via an idle gear 69.

  The roller link 68 is biased in a direction to push down the accumulated bill taking-in roller 64 according to the rotation (arrow a) of the bill taking-in direction of the feed roller shaft 65a, via a friction resistance member etc. Are connected.

  The return roller 66 is disposed so as to be pressed from below onto the feed roller 65, and is attached to the return roller shaft 66a via a torque limiter 66b.

  Furthermore, the bill batch loading device 600 is provided with a bill sensor (not shown) that detects a bill when it is inserted into the housing 61 from the bill receiving portion 60.

  The bill batch loading device 600 having the above-described structure is detachably attached to the front surface of the housing of the identification device 601 by fitting, engagement, and screwing.

  In the bill batch loading device 600 configured as described above, when the stacked bill PA is inserted into the housing 61 from the bill receiving portion 60, this is detected by a bill sensor (not shown), and the bill batch fetching accordingly The delivery drive motor 67 of the device 600 is driven.

  In the bill batch taking-in device 600, the feed roller shaft 65a and the feed roller gear 65b rotate (arrow a) with the driving of the feeding drive motor 67, and the roller link 68 swings downward according to the rotation of the feed roller shaft 65a. Then, the accumulated bill taking-in roller 64 is pressed against the accumulated bill PA (arrow b). At the same time, the rotation of the feed roller gear 65 b is transmitted to the take-in roller gear 64 b via the link gear 90. Thereby, the accumulated bill taking-in roller 64 is rotated (arrow c), and the accumulated bill PA is taken in.

  Subsequently, the feed roller 65 starts to rotate in the direction of arrow a when the stacked bill taking-in roller 64 rotates a predetermined amount and the leading end of the stacked bill PA reaches the feed roller 65. When the first bill P is taken in between the feed roller 65 and the return roller 66, the rotational driving force is transmitted from the feed roller 65 to the return roller 66 via the bill P. Like the feed roller 65, the return roller 66 rotates in the direction (arrow e) for feeding the bill P to the bill delivery port 61c. However, when two or more bills are taken in between the rollers 65 and 66, the frictional force between the bills P is smaller than the frictional force between the return roller 66 and the bills P, and by the action of the torque limiter 66b. The return roller 66 reversely rotates (arrow d) and pushes back the second and subsequent bills. Thus, the bills P can be fed out one by one from the bill delivery port 61c.

Patent No. 3751519 gazette

  However, in the above-described batch loading device 600, the number of bills that can be batch loaded can be determined by the vertical movement width of the stacked bill loading roller 64 supported by the roller link 68 swinging up and down, that is, the swing width of the roller link 68 Get restricted. The swing width of the roller link 68 is limited because it is difficult to secure a swing space for the roller link 68 and the take-in roller gear 64b in the limited space inside the upper housing 61b. Therefore, there is a problem that it is not possible to insert a large amount of banknotes larger than the swing width of the roller link 68 into the batch loading device 600.

  In addition, the roller link 68 causes the feed roller shaft 65 a to be a friction resistance member or the like so that the roller link 68 is urged in the direction to push down the stacked banknote pickup roller 64 according to the rotation (arrow a) of the feed roller shaft 65 a. It is combined through. Therefore, when the feed roller shaft 65a is rotating in the direction of arrow a, the stacked bill taking-in roller 64 is urged in the direction of arrow b and always pressed against the upper surface of the stacked bill PA (arrow b). Therefore, when a problem occurs, such as when no bill P is fed out from the stacked bill PA to the gap between the feed roller 65 and the return roller 66 (for example, the bill P at the uppermost position of the stacked bill PA is If the operator can not separate the lower banknotes P by sticking to each other, etc.), the operator temporarily stops the operation of the batch loading device 600, applies vibration or an external force to the stacked banknotes PA by hand, and balances the stacked banknotes PA. It is necessary to break down the stacked bills PA so that the bills P can be separated one by one. Therefore, there is a problem that when a problem occurs in the delivery of the banknotes, an operation for the operator to return to the normal delivery processing is required.

  The present invention has been made to solve such a problem, and enables batch insertion of paper sheets such as a large number of accumulated banknotes, and a failure occurs when paper sheets are fed one by one. Even in such a case, the apparatus itself solves the problem and provides a sheet processing apparatus capable of automatically returning to the normal delivery processing.

In order to solve the above-mentioned problems, a sheet processing apparatus according to the present invention is a sheet processing apparatus for delivering sheets one by one from a plurality of stacked sheets, and the stacked A storage space having a size capable of storing a plurality of paper sheets, a communication between the storage space and the outside, and a size in which the plurality of accumulated paper sheets can be collectively inserted into the storage space insertion opening having the outlet with the an opening width narrower than the insertion opening communicates with the housing space of at least one of the paper sheet can be fed an opening width, and a bottom surface of the accommodating space And at least one of the plurality of sheets stored in the storage space, and a sheet insertion portion having a bottom wall on which the plurality of stacked sheets can be placed. A delivery roller for delivering the sheets of the sheet toward the delivery port; A separating and conveying unit for separating and conveying the sheets delivered to the delivery port one by one in a direction passing through the delivery port; a driving unit for rotating the delivery roller and driving the separation and transport unit; , the relative position of the previous SL feed roller and the paper sheet, the feed roller is positioned in the stacking direction end portion of the plurality of paper sheets accommodated inside the housing space sheet A bottom wall moving portion for moving the bottom wall so that the bottom wall can be alternatively changed between a first position capable of contacting the surface of the sheet and a second position at which the delivery roller is separated from the sheet surface And a control unit configured to control at least the operation of the position changing unit, the sheet detecting unit configured to detect the sheet conveyed by the separating and conveying unit, the control unit including: The paper sheet while the drive unit is in operation When the detection sensor does not detect the paper sheet transported by the separation transport unit, the delivery roller rotates the relative position between the delivery roller and the paper sheet by the drive of the drive unit. The bottom wall is alternated to allow the delivery roller to alternate between the first position accessible to the surface of the sheet and the second position spaced from the surface of the sheet. The bottom wall moving unit is controlled to reciprocate , and in the second position, the bottom wall separates the paper sheet into a position separated from the delivery roller .

  In this configuration, when collectively inserting paper sheets such as a plurality of accumulated banknotes into the storage space of the paper sheet insertion unit, the relative position between the delivery roller and the paper sheets is sent out by the position change unit. The roller can be at a second position spaced from the sheet. Thereby, batch insertion of a large number of accumulated paper sheets is possible without the delivery roller interfering with the sheets.

  Further, in the above configuration, when sending out a plurality of accumulated paper sheets stored in the storage space one by one, the position changing unit moves either one or both of the delivery roller and the bottom wall, A sheet positioned at an end in a stacking direction of a plurality of sheets stored inside the storage space with the relative position between the delivery roller and the sheets protruding inside the storage space The delivery roller is changed to a first position where the delivery roller can contact. In this state, by rotating the delivery roller by the drive unit, at least one of the plurality of sheets stored in the storage space is delivered toward the delivery port. Then, the paper sheet fed to the delivery port is separated and transported one by one in the direction of passing through the delivery port by the separation transport unit.

  Here, when carrying out the process of conveying the sheets one by one, the delivery roller is used for the reason that a plurality of accumulated sheets are large in frictional force between the sheets and can not be separated from each other. There are cases where it is not possible to send paper sheets to the delivery port. In such a case, the control unit detects the relative position between the delivery roller and the sheet, triggered by the fact that the sheet detecting sensor does not detect the sheet conveyed by the separating / conveying unit while the drive unit is operating. Of the position changing portion such that the first position at which the delivery roller can contact the sheet surface and the second position at which the delivery roller is separated from the sheet surface are alternately changed. Start control. By alternately changing the relative positions of the delivery roller and the sheet between the first position and the second position, the rotating delivery roller is positioned at the end of the stacking direction of the stacked sheets. Intermittently contact the surface of the paper sheet. A sheet contacting the rotating delivery roller is gradually delivered while being intermittently pressed by the delivery roller. At this time, the contact position between the delivery roller and the paper sheet is displaced, and the frictional force between the paper sheet is reduced, so that the paper sheet can be delivered. In other words, it is possible to forcibly break the balance of a plurality of stacked sheets by intermittent contact of the rotating delivery roller with the sheets. This makes it possible to return to a state where it is possible to deliver the paper sheet to the delivery port.

  As a result, even if a problem occurs when the sheets are fed one by one, the sheet processing apparatus itself can resolve the problem and automatically return to the normal delivery process. The return work by the operator becomes unnecessary.

Further, according to the above configuration, the position changing unit that changes a relative position between the feed-out roller and the paper sheet includes a bottom wall moving unit for moving the bottom wall constituting the bottom surface of the accommodation space. Therefore, the relative position between the delivery roller and the paper sheet can be easily changed between the first position and the second position by the vertical movement of the bottom wall on which the paper sheet inside the storage space is placed. Is possible. In addition, when the sheet detection sensor does not detect a sheet conveyed by the separation conveyance unit while the drive unit is in operation, the relative position between the delivery roller rotated by the drive of the drive unit and the sheet is The controller controls the bottom wall displacement to reciprocate the bottom wall to allow alternating between the one position and the second position. In the second position, the bottom wall separates the sheets into a position spaced from the delivery roller. As a result, the bottom wall and the paper sheets placed on the bottom wall move up and down, so that the rotating delivery roller can contact the paper sheets intermittently. As a result, it is possible to return to a state where it is possible to feed the paper sheet to the delivery port. In the above configuration, since the bottom wall and the sheets move up and down, it is possible to omit the mechanism that moves the delivery roller up and down.

  It is preferable to further include a pressing unit that presses the plurality of paper sheets stored inside the storage space toward the delivery roller.

  In this configuration, after the plurality of stacked paper sheets stored in the storage space of the paper sheet insertion unit are collectively inserted, the pressing unit presses the plurality of paper sheets toward the delivery roller. It is possible. This makes it possible to increase the friction between the delivery roller and the sheets positioned at the end of the stacking direction of the plurality of sheets. As a result, it is possible to more stably deliver the sheet to the delivery port by the delivery roller.

  An opening is formed in the bottom wall, and the delivery roller is disposed at a position projecting to the inside of the accommodation space through the opening in the first position, and is lower than the bottom wall in the second position. It is preferred to be placed in position.

  In such a configuration, the plurality of accumulated paper sheets are placed on the bottom wall in the state of being inserted into the storage space. In the first position, the delivery roller can abut against the surface of the lowermost sheet of the plurality of accumulated sheets by projecting into the interior of the storage space through the opening formed in the bottom wall in the first position. It is possible. Thus, the delivery roller can deliver the lowermost sheet to the delivery port. In addition, since the lowermost sheet is pressed against the bottom wall by the other sheets, it is possible to be sent out without wrinkles or sag while being guided to the bottom wall. Moreover, since the delivery roller is retracted below the bottom wall in the second position, the plurality of accumulated paper sheets abut on the bottom wall above the delivery roller when inserted into the storage space. Contact with the delivery roller is reliably avoided. Therefore, batch insertion of a plurality of accumulated paper sheets can be reliably performed.

  The control unit is further provided with an alarm unit that issues an alarm when there is an operation abnormality of the sheet processing apparatus, and the control unit controls the relative position between the delivery roller and the sheet by the position change unit. The position change unit, when the sheet detecting sensor does not detect the sheet conveyed by the separation conveyance unit after the predetermined number of changes between the first position and the second position. It is preferable to control so as to stop the operation with respect to and to issue an alarm to the alarm unit.

  In such a configuration, the sheet detection sensor detects the separation and conveyance unit after the position changing unit changes the first position and the second position for the relative positions of the delivery roller and the sheets a predetermined number of times. When the sheet conveyed by is not detected, that is, when it is not possible to return to the normal sheet feeding process, the operation of the position changing unit can be stopped and the alarm unit can automatically give an alarm. Therefore, the worker does not have to monitor or manage the sheet processing apparatus until there is an alarm.

  It is preferable that the paper sheet is a bill, and the paper sheet processing apparatus further includes an identification unit that identifies the bill conveyed one by one from the separation conveyance unit. In this configuration, it is possible to identify the banknotes conveyed one by one from the separating and conveying unit by the identification unit.

  As described above, according to the paper sheet processing apparatus of the present invention, it is possible to batch insert paper sheets such as a large number of accumulated banknotes, and there is a problem when sending out the paper sheets one by one. Even when it occurs, the apparatus itself can solve the problem and automatically return to the normal delivery process.

  Hereinafter, the bill processing apparatus which is an embodiment of a paper sheet processing apparatus of the present invention will be described in more detail with reference to the drawings.

  The bill processing apparatus 1 shown in FIG. 1 is an apparatus for processing a bill, which is a type of paper sheet. The bill processing apparatus 1 is capable of collectively inserting the accumulated bills PA (see FIG. 4), which is a bundle of a plurality of bills accumulated (that is, laminated) in the vertical direction, into the bill insertion portion 9 of the depositing unit 2 The banknotes P are sent out one by one from the batch-inserted stacked banknotes PA by the 10 and the separate transport unit 32, and the banknotes P are identified by the identification unit 3.

  Specifically, the bill processing apparatus 1 includes a deposit unit 2 having a bill insertion unit 9, an identification unit 3, and a first conveyance unit 4 for conveying the bills P one by one from the deposit unit 2 to the identification unit 3; Among the banknotes P identified by the identification unit 3, the banknote storage unit 5 for storing the banknotes P to be stored, and the return port 26 for returning the banknotes P to be returned among the banknotes P identified by the identification unit 3 , The second transport unit 7 for transporting the banknote P identified by the identification unit 3 to any of the banknote storage unit 5 and the return unit 6, and the control unit 27 incorporated in any of these units. And an alarm unit 35.

  On the front side (left side in FIG. 1) of the bill processing apparatus 1, a later-described deposit port 9b of the bill insertion portion 9 of the deposit unit 2 and a return port 26 of the return unit 6 are arranged vertically. Therefore, on the front side of the bill processing apparatus 1, it is possible to easily perform the work of batch insertion of the accumulated bills PA and the work of collecting the returned bills P.

  The deposit unit 2 is, as shown in FIGS. 1 to 4, a bill insertion portion 9 into which the accumulated bills PA are inserted, and a delivery roller for delivering the bills P from the accumulated bills PA to a later described delivery port 9 c of the bill insertion portion 9. A pick roller 10, a separation conveyance unit 32 that separates and conveys the banknotes P one by one, a depositing unit drive motor 13 that is a drive unit that drives the pick roller 10 and the separation conveyance unit 32, and the pick roller 10; It has a pick roller solenoid 28 which is a delivery roller moving unit which moves up and down, and a deposit unit stop sensor 17 which is a paper sheet detection sensor for detecting a bill P transported from the separating and transporting unit 32.

  Furthermore, the depositing unit 2 includes a shutter 30 for closing a delivery port 9c described later, a shutter solenoid 29 for moving the shutter 30 up and down to open and close the shutter 30, and a bill P inside a storage space 9a described below of the bill insertion portion 9 It has a depositing unit internal sensor 31 to be detected, and a pressing unit 33 to press the stacked bills PA toward the pick roller 10.

  Hereinafter, each configuration of the depositing unit 2 will be described in more detail.

As shown in FIGS. 3 to 4, the bill insertion portion 9 communicates between the accommodation space 9 a having a size capable of accommodating the accumulated bills PA, the accommodation space 9 a and the outside, and the accumulated bills PA collectively A deposit port 9b as an insertion slot for paper sheets having a size that can be inserted into the storage space 9a, and an opening width narrower than the deposit port 9b and communicated with the storage space 9a and at least one sheet And a delivery port 9c having an opening width capable of delivering the banknote P.

  Furthermore, the bill insertion portion 9 constitutes a bottom surface of the storage space 9a, and has a bottom wall 9d on which the accumulated bills PA can be placed. The bottom wall 9d is formed with an opening 9e having a size in which the pick roller 10 can be retracted. The bottom wall 9d is inclined so as to descend from the deposit port 9b to the delivery port 9c so that the bills P can easily move to the delivery port 9c, but may be horizontal.

  The pick roller 10 is rotatably supported by a horizontally extending rotation shaft. Pick roller 10 is rotated by receiving the rotational driving force of depositing unit drive motor 13 via a transmission mechanism (not shown) (for example, a mechanism having a gear, an endless belt, etc.). Thereby, the pick roller 10 can send out at least one banknote P of the some banknotes P accommodated in the inside of the accommodation space 9a toward the delivery port 9c.

  As shown in FIGS. 3 to 4, the pick roller solenoid 28 moves the pick roller 10 up and down to project a plurality of bills P stored in the storage space 9 a in a state of being projected inside the storage space 9 a. Of the first position (that is, the upper position of the pick roller 10 shown in FIG. 4) capable of contacting the surface of the banknote P located at the end of the stacking direction D (the lower end in FIG. 4) Functions as a delivery roller moving unit that moves between the second position (i.e., the lower position of the pick roller 10 shown in FIG. 3) separated from the surface of the bill P in a state in which it does not protrude inside.

  In other words, the delivery roller moving unit such as the pick roller solenoid 28 moves the pick roller 10 so that the relative position between the pick roller 10 and the stacked banknotes PA can be reduced. A first position capable of coming into contact with the surface of the banknote P located at the end of the stacking direction D among the stacked banknotes PA stored in the storage space 9a in a state of being projected into the storage space 9a described later; This is included in the concept of a position changer which causes the pick roller 10 to change alternatively between the pick roller 10 and a second position spaced from the surface of the bill P.

  The delivery roller moving part of the present invention is not limited to the pick roller solenoid 28, and the pick roller 10 (delivery roller) reciprocates between the first position and the second position shown in FIGS. It only needs to have a movable configuration.

  In the first position, the pick roller 10 shown in FIGS. 3 to 4 is disposed so as to protrude inside the accommodation space 9a through the opening 9e, and in the second position, disposed below the bottom wall 9d.

  The second position shown in FIG. 4 may be any position where the pick roller 10 can be separated from the surface of the bill P, and if it does not contact the bill P, it slightly protrudes inside the accommodation space 9a. It is also good.

  As shown in FIGS. 3 to 4, the separating / conveying unit 32 has a configuration for separating and conveying the banknotes P delivered to the delivery port 9 c one by one in the direction C passing through the delivery port 9 c. Specifically, the separating and conveying unit 32 has a feed roller 12 and a return roller 11. The feed roller 12 and the return roller 11 are separately and rotatably supported by two rotary shafts extending in the horizontal direction, respectively, and arranged vertically above and below the conveyance path of the banknote P so that both surfaces of the banknote P can be contacted. It is done. That is, the feed roller 12 is disposed below the transport path of the bill P, while the return roller 11 is disposed above the transport path of the bill P (that is, on the stacking side of the bill P). The feed roller 12 and the return roller 11 contact the bill P being conveyed from both sides, and are set at intervals which allow the passage of one bill P.

  The return roller 11 has a torque limiter (not shown) on the rotational drive shaft of the return roller 11 in order to prevent the second and subsequent bills P from being taken in, as will be described later. The torque value is set to be lower than the frictional force generated between the return roller 11 and the banknotes P, over the frictional force generated between the banknotes.

  In a state where the feed roller 12 is in contact with the lower surface of the bill P, the feed roller 12 receives and rotates the rotational driving force of the depositing unit drive motor 13 via a transmission mechanism (for example, a mechanism having a gear or an endless belt). Thereby, the feed roller 12 applies a propelling force to the bill P in the direction C passing through the delivery port 9c. On the other hand, in a state where the return roller 11 is in contact with the upper surface of the bill P, the rotational drive force of the depositing unit drive motor 13 is transmitted through the torque limiter to the drive force of the return roller 11. The limit torque of the torque limiter is set so as to be smaller than the frictional force between the feed roller 12 and the return roller 11 and larger than the frictional force generated between the bills. In the roller 11, the drive force from the feed roller 12 exceeds the limit torque of the torque limiter, and the return roller 11 rotates in the counterclockwise direction.

  When one bill P is fed between the feed roller 12 and the return roller 11, the return roller 11 contacts the upper surface of the bill P, and the rotational driving force of the feed roller 12 is returned via the bill P. Since it is transmitted to the roller 11 and the frictional force between the return roller 11 and the bill P overcomes the torque limit of the torque limiter, it rotates in synchronization with the movement of the bill P to feed one bill P. Tolerate. However, when two or more bills P are fed between the feed roller 12 and the return roller 11, the frictional force between the feed roller 12 and the bill P and the frictional force between the return roller 11 and the bill P are between the bills. Since the rotational drive force from the feed roller 12 is interrupted by the slip phenomenon between bills because it exceeds the frictional force that acts, the return roller 11 is rotated clockwise by the action of the torque limiter, and the two sheets It acts to return the banknotes after the eyes to the side of the accommodation space 9a. Thus, the delivery of two or more bills P is avoided, and the delivery of the bills P one by one becomes possible.

  In the present invention, the separating and conveying unit 32 may be configured to separate and convey the bills P delivered to the delivery port 9 c one by one in the direction C passing through the delivery port 9 c. The configuration is not limited to the configuration provided with the feed roller 12 and the return roller 11 of FIG.

  As described above, the depositing unit drive motor 13 rotates the pick roller 10 and, at the same time, rotates the drive of the separation conveyance unit 32, specifically, the feed roller 12 and the return roller 11. In the present embodiment, the rotation of the pick roller 10 and the driving of the separation conveyance unit 32 are performed by the common depositing unit drive motor 13, but the present invention is not limited to this. That is, the drive unit of the present invention may separately include a motor for rotating the pick roller and a motor for driving the separation and conveyance unit.

  The deposit unit stop sensor 17 is a bill detection sensor that detects bills P conveyed to the first conveyance unit 4 one by one by the separation conveyance unit 32. The deposit unit stop sensor 17 is disposed downstream of the separating / conveying unit 32 in the conveyance direction C (see FIG. 4) of the banknotes P in the conveyance direction C of the banknotes P. The deposit unit stop sensor 17 may be any sensor that detects the presence or absence of the bill P, for example, a photo sensor or an infrared sensor that optically detects the presence or absence of the bill P, but other detection means May be. Moreover, the money_receiving | payment unit stop sensor 17 is not limited to one piece. For example, the additional depositing unit stop sensor 117 (see FIG. 1) may be installed downstream of the transport path from the depositing unit stop sensor 17.

  The control unit 27 controls the operation of the feed roller moving unit, specifically, the pick roller solenoid 28, which is at least included in the concept of the position changing unit. The control unit 27 controls the pick roller 10 to be rotated by the driving of the depositing unit drive motor 13 when the deposit unit stop sensor 17 does not detect the bill P conveyed by the separation transport unit 32 while the depositing unit drive motor 13 is operating. The pick roller solenoid 28 is controlled to reciprocate between the first position (upper position in FIG. 4) and the second position (lower position in FIG. 3). This makes it possible to alternately change the relative positions of the pick roller 10 and the stacked banknotes PA between the first position and the second position.

  In the bill processing apparatus 1 configured as described above, when collectively inserting the accumulated bills PA into the accommodation space 9 a of the bill insertion portion 9, the relative positions of the pick roller 10 and the accumulated bills PA by the pick roller solenoid 28. Changing to the second position, specifically, moving the pick roller 10 to the second position (the lower position in FIG. 3) separated from the surface of the bill P in a state in which the pick roller 10 does not protrude into the storage space 9a. Is possible. Thereby, batch insertion of a large number of accumulated bills P is possible without the pick roller 10 interfering with the bills P.

  Further, in the above configuration, when the stacked banknotes PA stored in the storage space 9a are fed one by one, the pick roller solenoid 28 changes the relative position between the pick roller 10 and the stacked banknotes PA to the first position. Specifically, the end portion in the stacking direction D of the plurality of bills P accommodated in the accommodation space 9a in a state in which the pick roller 10 is projected inside the accommodation space 9a (lower end in FIG. 4 ) To the first position (upper position in FIG. 4) capable of contacting the face of the bill P located at. In that state, by rotating the pick roller 10 by the depositing unit drive motor 13, at least one bill P of the plurality of bills P accommodated in the accommodation space 9a is sent out toward the outlet 9c. . And bill P sent out to sending out mouth 9c by feed roller 12 and return roller 11 of separation conveyance section 32 is separated and conveyed one by one in the direction which passes sending out mouth 9c concerned.

  Here, when carrying out the process of conveying the bills P one by one, the pick roller 10 feeds the bills P because the frictional force between the bills P is large and can not be separated from each other. It may not be possible to send it out to the exit 9c. In such a case, the control unit 27 sets the pick roller 10 and the accumulation unit triggered by the fact that the banknotes P conveyed by the separation conveyance unit 32 are not detected while the reception unit drive motor 13 is operating. The relative position with the bill PA is alternately changed between the first position and the second position, specifically, the pick roller 10 is moved to reciprocate between the first position and the second position. Control of the roller solenoid 28 is started. As described in FIG. 10, which will be described later, when the pick roller 10 is moved up and down while being driven by the depositing unit drive motor 13 as in the unrolling retry process shown in FIG. Intermittently contacts the face of the bill P located at the end of the direction D. The bills P in contact with the pick roller 10 in a rotating state are gradually fed while being intermittently pressed by the pick roller 10. At this time, the contact position between the pick roller 10 and the bill P is displaced, and the frictional force between the bills P is reduced, so that the bill P can be fed out. In other words, it is possible to forcibly break the balance of the stacked banknotes PA by the pick roller 10 intermittently contacting the stacked banknotes PA by the vertical movement of the pick roller 10 in the rotating state. As a result, it becomes possible to return to a state in which the bills P can be sent out to the delivery port 9c.

  As a result, even when a problem occurs when feeding out the banknotes P one by one, the banknote handling apparatus 1 itself can eliminate the problem and automatically return to the normal delivery process, and the worker can The return work due to

  In the banknote handling apparatus 1 of the present embodiment, a delivery roller moving unit, specifically, a pick roller solenoid 28, is used as a position changing unit that changes the relative position between the pick roller 10 and the stacked banknotes PA. There is. Therefore, it is possible to easily change the pick roller 10 between the first position and the second position by the up and down movement of the pick roller 10. Further, when the bill P on which the deposit unit stop sensor 17 is transported is not detected by the separation transport unit 32 while the depositing unit drive motor 13 is in operation, the control unit 27 determines that the pick roller 10 has the first position and the second position. By controlling the pick roller solenoid 28 to reciprocate between the two, it becomes possible for the pick roller 10 in a rotating state to intermittently contact the stacked bills PA. As a result, it becomes possible to return to a state in which the bills P can be sent out to the delivery port 9c. In the above configuration, the operation of the reciprocation of the pick roller 10 is not affected by the weight of the stacked banknotes PA, so the response is good.

  As shown in FIGS. 1 and 3 to 4, the pressing portion 33 has a configuration for pressing the plurality of bills P stored in the storage space 9 a toward the pick roller 10.

  The pressing portion 33 shown in FIG. 1 is disposed on the upper side of the accommodation space 9 a of the bill insertion portion 9. The pressing portion 33 receives the driving force of the pressing plate 14 housed in the housing space 9 a so as to be movable in the vertical direction, the pressing plate drive motor 15 capable of rotating in the forward and reverse directions, and the pressing plate drive motor 15. And a push plate moving unit 16 for reciprocating the plate 14 in the vertical direction.

  The push plate 14 has a shape capable of pressing the stacked bill PA downward toward the pick roller 10, and specifically, has a contact surface 14a that abuts on the top surface of the stacked bill PA.

  The pressing plate moving unit 16 has a configuration capable of reciprocating the pressing plate 14 in the vertical direction by receiving the driving force of the pressing plate drive motor 15. For example, the push plate moving unit 16 shown in FIGS. 3 to 4 receives a rotational drive force of the push plate drive motor 15 and rotates in both forward and reverse directions with the pinion gear 16a and the pinion gear 16a. It has 16b, a pair of link arms 16c and 16d, and a torsion spring 16e.

  The pair of link arms 16c, 16d are rotatably connected to each other at their respective intermediate positions by pins or the like. The upper end of the link arm 16c abuts on the downward extending projection 16b1 of the rack 16b, and can displace the position of the upper end following the movement of the rack 16b. The lower end of the link arm 16 c abuts on the upper surface of the push plate 14 and can slide along the upper surface of the push plate 14.

  The upper end of the link arm 16d is connected to the torsion spring 16e. The torsion spring 16e applies a rotational biasing force to the link arm 16d in such a direction as to swing downward (rotation in the counterclockwise direction in FIG. 4). The lower end of the link arm 16d is rotatably connected to the push plate 14 by a pin or the like.

  In the pressing unit 33 configured as described above, after the stacked banknotes PA stored in the storage space 9a of the banknote inserting unit 9 are collectively inserted, the stacked banknote PA is directed to the pick roller 10 by the pressing unit 33. It is possible to press. Specifically, when the push plate drive motor 15 rotates forward, the pinion gear 16a rotates forward in the push plate moving unit 16, and the rack 16b meshing with the pinion gear 16a moves in a predetermined direction (rightward in FIG. 4). Thereby, the upper end of the link arm 16c approaches the upper end of the link arm 16d. At this time, due to the downward rotational biasing force that the link arm 16d receives from the torsion spring 16e, the pair of link arms 16c and 16d are shown by the two-dot chain line in FIG. 4 from the folded state shown in FIG. It stands up while crossing each other. As a result, the push plate 14 can be pressed downward by the lower ends of the pair of link arms 16 c and 16 d to press the stacked banknotes P downward. On the other hand, when the push plate drive motor 15 reversely rotates, the pinion gear 16a reverses in the push plate moving unit 16, and the rack 16b moves in the opposite direction (left direction in FIG. 4). The link arms 16 c and 16 d return to the folded state, and accordingly, the push plate 14 can be moved upward to end the pressing operation of the stacked bills PA by the push plate 14. In this state, since the push plate 14 is retracted above the accommodation space 9a of the bill insertion portion 9, interference with the accumulated bill PA inserted from the deposit port 9b is avoided.

  As described above, by pressing the stacked banknotes PA toward the pick roller 10 by the pressing unit 33, the banknotes positioned at the end (the lower end in FIG. 4) of the pick roller 10 and the plurality of banknotes P in the stacking direction D It is possible to increase the friction with P. As a result, it is possible to more stably deliver the banknote P to the delivery port 9 c by the pick roller 10.

  Moreover, in said structure, the banknote insertion part 9 comprises the bottom face of the accommodation space 9a, and has the bottom wall 9d which can mount the accumulated banknote PA. An opening 9e is formed in the bottom wall 9d. Pick roller 10 is disposed at a position projecting to the inside of accommodation space 9a through opening 9e in the first position shown in FIG. 4 and at a position lower than bottom wall 9d in the second position shown in FIG. Be done. In this configuration, the stacked bills PA are placed on the bottom wall 9d in a state of being inserted into the storage space 9a. In the first position shown in FIG. 4, the pick roller 10 projects into the inside of the storage space 9 a through the opening 9 e formed in the bottom wall 9 d, thereby ensuring that the surface of the bill P of the lowest layer of stacked bills PA is hit. It is possible to touch. Thereby, the pick roller 10 can send out the bill P in the lowermost layer to the delivery port 9c. In addition, since the lowermost bill P is pressed against the bottom wall 9d by another bill P, it becomes possible to be fed out without wrinkles or slack in a state of being guided by the bottom wall 9d. Moreover, since the pick roller 10 is retracted below the bottom wall 9d in the second position shown in FIG. 3, the stacked banknotes PA are bottomed above the pick roller 10 in the state of being inserted into the storage space 9a. It abuts against the wall 9 d and contact with the pick roller 10 is reliably avoided. Therefore, it becomes possible to perform batch insertion of accumulated bills PA reliably.

  The pick roller 10 may be disposed above the accommodation space 9 a, and the delivery port 9 c may also be disposed at a height position corresponding to the pick roller 10. In this case, the pressing portion 33 is unnecessary. Even with such a configuration, it is possible to abut against the uppermost bill P of the stacked banknotes PA accommodated in the accommodation space 9a and send it out to the delivery port 9c. Further, as described above, when a problem occurs in the delivery of the bill P, the pick roller 10 is moved up and down to intermittently contact the bill P on the uppermost layer of the accumulated bill PA, thereby solving the problem. It is possible.

  Below, other structures other than the money_receiving | payment unit 2 in the banknote processing apparatus 1 are demonstrated.

  As shown in FIG. 1, the identification unit 3 has a configuration for identifying the banknotes P conveyed one by one from the separation conveyance unit 32 via the first conveyance unit 4. The identification unit 3 identifies, for example, the denomination of the banknote P (which amount is the banknote) and the authenticity, but may identify the banknote P under more detailed conditions (for example, identification of new and old). As described above, since the banknote processing apparatus 1 includes the identification unit 3, the banknotes P conveyed one by one from the separation conveyance unit 32 can be identified by the identification unit 3.

  The first transport unit 4 has a configuration for transporting the banknotes P transported one by one from the depositing unit 2 to the identification unit 3. Specifically, the first transport unit 4 includes a transport path 34 in which the bills P are transported, and a plurality of transport rollers 19 which are disposed along the transport path 34 and transport the bills P along the transport path 34; It has an identification unit conveyance motor 18 that rotationally drives the plurality of conveyance rollers 19, and an identification unit front position sensor 20 disposed at a position along the conveyance path 34 and detecting a bill P conveyed along the conveyance path 34. .

  The rotational drive force of the identification unit transport motor 18 is transmitted to each transport roller 19 via a transmission mechanism (not shown) (for example, a mechanism having a gear or an endless belt).

  The banknote storage unit 5 has a configuration capable of storing the banknotes P to be stored among the banknotes P identified by the identification unit 3. The bill storage unit 5 is configured of, for example, a safe having a lockable door. Although it is preferable that the bill storage unit 5 has a configuration for storing the bills P transferred from the second conveyance unit 7 separately by denomination, for example, a configuration for collectively storing the bills P without dividing the denominations ( It may be a so-called "drop-off configuration". Further, the bill storage unit 5 may be configured to be separable from other parts of the bill processing apparatus 1.

  The return unit 6 is configured to have the return port 26 for returning the banknote P to be returned among the banknotes P identified by the identification unit 3 as described above.

  The second transport unit 7 has a configuration capable of transporting the banknote P identified by the identification unit 3 to any of the banknote storage unit 5 and the return unit 6. Specifically, the narrowing conveyance path 21 capable of conveying the bill P identified by the identification unit 3 to the bill storage unit 5 and the return unit 6 and the narrowing conveyance path 21 are disposed to narrow the bill P. A plurality of conveyance rollers 22 that convey along the holding conveyance path 21, a pinching conveyance motor 23 that rotationally drives the plurality of conveyance rollers 22, and a pinching conveyance position sensor 24 that detects bills P in the pinching conveyance path 21. And a path switching solenoid 25.

  The holding conveyance path 21 has a configuration capable of conveying the bill P to the bill storage unit 5 and the return unit 6 in a state of holding the bill P from both sides. Specifically, the narrowing conveyance path 21 is configured by arranging a pair of long metal plates with a small gap (specifically, a gap of a size that can be transported while sandwiching the bill P). Be done. The pinching conveyance path 21 has an opening which enables the conveyance roller 22 to contact the bill P passing through the gap inside the pinching conveyance path 21.

  The narrowing conveyance path 21 has a first portion 21 a extending from the identification unit 3 to the path switching solenoid 25, and a second portion 21 b and a third portion 21 c branched from the path switching solenoid 25. The second portion 21 b extends from the path switching solenoid 25 to the bill storage portion 5. The third portion 21 c extends from the path switching solenoid 25 to the return unit 6.

  The path switching solenoid 25 is configured to alternatively connect the first portion 21a of the sandwiching and conveying path 21 to any one of the second portion 21b and the third portion 21c. Thereby, the second transport unit 7 can transport the banknote P identified by the identification unit 3 to either the banknote storage unit 5 or the return unit 6 according to the identification result.

  The rotational driving force of the pinching conveyance motor 23 is transmitted to each conveyance roller 22 via a transmission mechanism (for example, a mechanism having a gear, an endless belt, etc.) not shown.

  The alarm unit 35 issues an alarm when there is an operation abnormality of the banknote handling apparatus 1, and is, for example, a buzzer or a lamp. Moreover, it is a display (not shown) which displays the operation screen connected to the banknote processing apparatus 1 as the alarm part 35, Comprising: The display etc. which can display an alarm may be used.

  The control unit 27 determines the change between the first position and the second position of the relative position between the pick roller 10 and the stacked banknotes PA by the position change unit, specifically, the reciprocation of the pick roller 10. When the depositing unit stop sensor 17 does not detect the bill P conveyed by the separating / conveying unit 32 after performing the number of times (for example, ten times), the pick roller solenoid 28 is controlled to stop its operation, and Control is performed to issue an alarm to the alarm unit 35.

  In this configuration, as in the unrolling retry process shown in FIG. 10 described later, the banknotes P conveyed by the separating / conveying unit 32 are not detected after the depositing unit stop sensor 17 has performed the reciprocating movement of the pick roller 10 a predetermined number of times. When it is not possible to return to the normal delivery process of the banknotes P, the stop of the reciprocal movement of the pick roller 10 by the pick roller solenoid 28 and the alarm by the alarm unit 35 can be automatically performed. Therefore, the worker does not have to monitor or manage the banknote handling apparatus 1 until there is a warning.

  The control unit 27 is incorporated in any of the units 2 to 4 and 6 described above, and is incorporated, for example, in the second conveyance unit 7 on the back side (right side in FIG. 1) of the banknote handling apparatus 1.

  As shown in FIG. 2, the control unit 27 is the above-described drive element inside the bill processing apparatus 1, for example, the deposit unit drive motor 13, the push plate drive motor 15, the identification unit transport motor 18, the sandwich transport motor 23, and the path. The respective operations of the switching solenoid 25, the pick roller solenoid 28, and the shutter solenoid 29 are controlled. The control unit 27 also controls the operation of the alarm unit 35. When the control unit 27 controls these drive elements and the alarm unit 35, the control unit 27 receives a control signal from the outside or a detection signal from the above sensor inside the banknote handling apparatus 1, for example, the deposit unit stop sensor 17 By receiving detection signals from the deposit unit internal sensor 31, the identification unit front position sensor 20, and the nipping conveyance position sensor 24, the drive element and the alarm unit 35 are controlled.

  Below, operation | movement description of the banknote processing apparatus 1 comprised as mentioned above is demonstrated, referring the flowchart shown by FIGS.

  First, the procedure of the basic operation of the banknote handling apparatus 1 will be described using the flowcharts shown in FIGS.

  First, the stacked bills PA are inserted into the storage space 9a of the bill insertion portion 9, and a series of deposit counting processes shown in FIGS. The start of the process is triggered by the detection of the stacked banknotes PA by the deposit unit internal sensor 31 of the banknote insertion unit 9 as a trigger.

  In step S1 of FIG. 5, the control unit 27 operates the pick roller solenoid 28 to control the pick roller solenoid 28 so as to raise the pick roller 10. As a result, as shown in FIG. 4, the pick roller 10 is disposed at a first position projecting inside the storage space 9 a of the bill insertion portion 9.

  Next, in step S2, the control unit 27 starts the operation of the push plate drive motor 15, and controls the push plate drive motor 15 so as to lower the push plate 14. As a result, the stacked bills PA are pressed by the push plate 14 from above to the pick roller 10.

  In steps S3 to S4, after the operation of lowering the pressing plate 14 in the above step S2 is held for 1.5 seconds, the pressing plate drive motor 15 is stopped.

  Then, in step S5, the operation of the pinching and conveying motor 23 of the second conveying unit 7 is started, and the pinching and conveying motor 23 is controlled to rotate the conveying roller 22.

  Then, in step S6, the operation of the identification unit conveyance motor 18 of the first conveyance unit 4 is started, and the identification unit conveyance motor 18 is controlled to rotate the conveyance roller 19.

  Then, in step S7, the control unit 27 performs speed adjustment processing on the identification unit conveyance motor 18 and the sandwiching conveyance motor 23. A specific example of the speed adjustment process will be described later.

  Next, in step S8 of FIG. 6, the control unit 27 starts the operation of the depositing unit drive motor 13 of the depositing unit 2 and processes the banknotes P in the depositing unit 2 (the banknotes P are separated and conveyed one by one) Control the deposit unit drive motor 13 so as to perform the following process). Specifically, rotation of the pick roller 10 and rotation of the feed roller 12 and the return roller 11 of the separation conveyance unit 32 are performed by the rotational driving force of the depositing unit drive motor 13. As a result, the bill P is sent out by the pick roller 10 to the delivery port 9 c of the bill insertion unit 9, and separated and transported one by one from the bill P delivered by the separation transport unit 32 to the delivery port 9 c.

  The banknotes P conveyed one by one are sent to the identification unit 3 through the first conveyance unit 4 and identified by the identification unit 3. The control unit 27 counts the number of the identified bills P as a denomination.

  When the deposit unit stop sensor 17 positioned on the downstream side of the transport direction C from the separation transport unit 32 in the transport direction of the banknote P is turned on while the banknote P in step S8 is being processed (step S9) That is, when the deposit unit stop sensor 17 detects a bill P, the control unit 27 controls to stop the operation of the deposit unit drive motor 13 in step S10 (ie, the pick roller 10, the feed roller 12). And stop the rotation of the return roller 11).

  Thereafter, the control unit 27 determines whether the deposit unit stop sensor 17 is OFF (step S11) and whether the bill insertion unit 9 has a bill (step S12).

  Here, when the depositing unit stop sensor 17 is OFF in step S10, the bill P completely passes the position of the depositing unit stop sensor 17, and the depositing unit stop sensor 17 does not detect the bill P. It is time. Further, when there is no bill in the bill insertion portion 9 in step S12, the bill P is not detected by the depositing unit internal sensor 31.

  In steps S11 to S12, when deposit unit stop sensor 17 is OFF and there is no bill in bill insertion portion 9, control portion 27 controls identification unit conveyance motor 18 and pinch conveyance motor 23 in steps S13 to S14. Control to stop the operation. Thereby, conveyance of the banknote P in the 1st conveyance unit 3 and the 2nd conveyance unit 7 stops, and the process of a series of deposit counting is complete | finished.

  When there is a bill in the bill insertion portion 9 in step S12, the process returns to step S8, and the process of rolling the bill P is performed again.

  Next, the procedure of a specific deposit counting and kneading process of the banknote handling apparatus 1 will be described using the flowcharts shown in FIGS. The procedure of the flowcharts shown in FIGS. 7 to 10 more specifically shows the procedure of the flowcharts of FIGS. 5 to 6 described above, and the basic flow is the same as that of FIGS.

  In the series of deposit counting / boiling processing shown in the flowchart of FIG. 7, when the control unit 27 receives a deposit count command (step S21), deposit count pre-processing is performed in step S22.

  Specifically, the deposit counting pre-processing is performed according to the procedure shown in the flowchart of FIG.

  First, whether or not the bill P is present in the bill insertion portion 9 is confirmed using the depositing unit internal sensor 31 (step S31).

  When there is a bill P, the control unit 27 causes the push plate drive motor 15 to rotate forward to lower the push plate 14 in step S32. As a result, the stacked bills PA stored in the storage space 9 c of the bill insertion portion 9 are pressed downward by the push plate 14. At the same time, the control unit 27 operates the pick roller solenoid 28 to raise the pick roller 10 to the first position in FIG. 4. Thereby, pick roller 10 contacts bill P of the lowest layer of accumulation bill PA.

  Next, after holding the operation of step S32 for 1.5 seconds in steps S33 to S34, the control unit 27 stops the push plate drive motor 15 and operates the shutter solenoid 29 so that the outlet 9c of the bill insertion portion 9 is output. It is controlled to open the shutter 30 for opening and closing the shutter.

  Next, in step S35, the control unit 27 causes the identification unit conveyance motor 18 of the first conveyance unit 4 to rotate in the normal direction to rotate the conveyance roller 19, and causes the pinching conveyance motor 23 of the second conveyance unit 7 to rotate in the normal direction. The roller 22 is controlled to rotate.

  Thereafter, in step S34, the control unit 27 controls the identification unit transport motor 18 and the pinch transport motor 23 for speed adjustment processing, and the series of deposit count pre-processing ends.

Here, the speed adjustment processing is performed, for example, according to the following procedures 1 to 3. The identification unit conveyance motor 18 and the sandwiching conveyance motor 23 used here are stepping motors that rotate by a predetermined rotation angle according to a pulse signal transmitted from the outside.
1. The control unit 27 causes the identification unit conveyance motor 18 and the sandwiching conveyance motor 23 to perform 620 pulse operations (that is, rotational operations corresponding to 620 pulses).
2. Next, the control unit 27 obtains an average value of pulse cycles of the identification unit transport motor 18 and the pinch transport motor 23 within the range of 120 to 620 pulses.
3. Thereafter, the control unit 27 determines the transport speed of each bill P by the identification unit transport motor 18 and the sandwich transport motor 23 from the average value of the pulse cycle obtained in the above-described procedure 2.

The conditions for determining the transport speed are as the following conditions 1) to 3).
1) If the average pulse of either the identification unit transport motor 18 or the sandwich transport motor 23 is 1.15 ms (milliseconds) or more (if the transport speed is high), 15 of the average pulses of the motor with the slower transport speed Adjust the transport speeds of both motors 18 and 23 to the speed that has decreased by%.
2) When the shortest pulse is 1.00 ms or less for both the identification unit transport motor 18 and the sandwich transport motor 23 (when the transport speed is slow), the pulses of both motors 18 and 23 are 1.00 ms or less. Adjust the transport speed.
3) Under conditions other than the above conditions 1) and 2), the transfer speeds of both motors 18 and 23 are set to be the average pulse of either the identification unit transfer motor 18 or the pinch transfer motor 23, whichever is slower. Match.

  As described above, after the deposit count pre-processing in step S22 of FIG. 7 is completed, it is confirmed using the deposit unit internal sensor 31 whether there is a bill P in the bill insertion portion 9 (step S23 of FIG. 7).

  When the bill P is present, a bill breaking process is performed in step S24.

  More specifically, in the bill-making process in step S24, a series of bill-making processes shown in the flowchart of FIG. 9 are executed.

  First, in step S41 of FIG. 9, the control unit 27 causes the depositing unit drive motor 13 of the depositing unit 2 to rotate in the forward direction. Specifically, normal rotation of the depositing unit drive motor 13 causes normal rotation of the pick roller 10 and forward rotation of the return roller 11 and the feed roller 12 of the separation conveyance unit 32. As a result, the bill P is sent out by the pick roller 10 to the outlet 9 c of the bill inserting portion 9 and separated and transported one by one from the bill P sent out to the outlet 9 c by the separating / conveying portion 32. A peeping process is performed.

  When the deposit unit stop sensor 17 is turned on during forward rotation of the deposit unit drive motor 13 in step S41 (step S42), that is, when the deposit unit stop sensor 17 detects a bill P, control is performed in step S43. The unit 27 controls to stop the operation of the depositing unit drive motor 13 (that is, the rotation of the pick roller 10, the feed roller 12 and the return roller 11 is stopped, and the loosening process is ended).

  Here, when the deposit unit stop sensor 17 is not turned on in step S42, that is, when the deposit unit stop sensor 17 does not detect the bill P, after waiting for 500 ms in steps S47 to S48, the unrolling retry process is performed. Run.

  Specifically, in the loosening retry process of step S48, a series of loosening retry processes shown in the flowchart of FIG. 10 are executed.

  As shown in FIG. 10, when the number of retries is 10 or less (step S61), the control unit 27 stops the operation of the pick roller solenoid 28 and lowers the pick roller 10. As a result, the pick roller 10 is separated from the stacked bills PA in a rotating state.

  Thereafter, after waiting for 100 ms, the control unit 27 operates the pick roller solenoid 28 to raise the pick roller 10. As a result, the pick roller 10 contacts the lowermost bill P of the stacked bills PA in a rotated state, and gradually sends out the bills P while breaking the balance of the stacked bills PA.

  If the deposit unit stop sensor 17 is not turned on in step S42 of FIG. 9 even after the series of the loosening retry process is completed 10 times, it is determined in step S61 of FIG. 10 that the retry process has exceeded 10 times. The control unit 27 controls the alarm unit 35 to issue an alarm while stopping the loosening retry process.

  In the case where the additional deposit unit stop sensor 117 (see FIG. 1) is installed downstream of the deposit unit stop sensor 17 on the downstream side of the deposit unit stop sensor 17, the diagram is further illustrated. As shown in 9, as an additional step S42 ', a step is added to determine whether the additional depositing unit stop sensor 117 is ON (i.e., the bill P has been detected). In the additional step S 42 ′, when the additional depositing unit stop sensor 117 is not ON, the bill P is in a stopped state between the depositing unit stop sensor 17 and the additional depositing unit stop sensor 117. Therefore, the control part 27 performs an error process so that operation | movement of the banknote processing apparatus 1 may be stopped, as a conveyance error generate | occur | produced.

  As shown in FIG. 9, after the depositing unit drive motor 13 of the depositing unit 2 is stopped in step S43, the identification unit front position sensor 20 in the first conveyance unit 4 downstream of the depositing unit 2 in steps S44 to S45. Is ON (that is, when the identification unit front position sensor 20 detects the bill P) and when the deposit unit stop sensor 17 is OFF (that is, the deposit unit stop sensor 17 does not detect the bill P When it is confirmed that the identification unit transport motor 18 has been rotated by one pulse in step S46, the series of banknote distraction processing shown in FIG. 9 ends.

  If NO in step S44 to S45, the control unit 27 stops the operation of the bill processing apparatus 1 after 1.5 seconds (steps S49 to S50). Execute the process Similarly, if NO in the determination step of step S46, the control unit 27 stops the operation of the banknote handling apparatus 1 and executes an error process after 0.5 seconds (step SS51).

  After completion of the series of bill making processes shown in FIG. 9 described above, at step S25 in the flowchart shown in FIG. 7, the control unit 27 checks whether the bill making process has been properly performed. If normal, while there is a bill P in the bill insertion portion 9, a series of steps S23 to S25 including the bill breaking process are repeated. If not normal, the control unit 27 executes error processing. When the bill P is lost in the bill insertion portion 9 (that is, when Step S23 is No), it is determined whether there is a bill P being conveyed (Step S26). In step S26, the control unit 27 determines whether the bill P is being conveyed, depending on whether the recognition unit front position sensor 20 of the first conveyance unit 4 and the pinching conveyance position sensor 24 of the second conveyance unit 7 have detected the bill P. It is determined whether or not there is

  When there is no bill P being conveyed in step S26, a series of deposit counting and kneading processing shown in FIG. 7 is completed.

  In the bill processing apparatus 1 of the present embodiment, the operation control of the path switching solenoid 25 of the second conveyance unit 7 is performed as follows according to the flow chart of the deposited bill allocation process shown in FIG.

  In the deposited bill distributing process shown in FIG. 11, first, at step S71, the control unit 27 determines whether the nipping and conveying position sensor 24 of the second conveying unit 7 is ON (that is, the nipping and conveying position sensor 24 applies the bill P). Whether detected)).

  Next, in steps S72 to S74, the control unit 27 uses all of tracking data, identification unit accept notification, and deposit data as data necessary for authenticating that the bill storage unit 5 such as a safe receives the bill P. Determine if there is.

  If all the conditions in the above steps S71 to S74 are Yes, in step S75, the control unit 27 controls the path switching solenoid 25 of the second conveyance unit 7 to perform a receiving operation. Specifically, the control unit 27 switches the pinching and conveying path 21 to a path along which the bill P is conveyed to the bill storage portion 5 (that is, the first portion 21a and the second portion 21b of the pinching and conveying path 21). Control the switching of the path switching solenoid 25.

  On the other hand, if at least one of the conditions from step S71 to step S74 described above is present, the control unit 27 controls the path switching solenoid 25 to perform return operation in step S76. Specifically, the control unit 27 causes the pinching and conveying path 21 to be switched to a path in which the bill P is conveyed to the return port 26 of the return unit 6 (that is, the first portion 21a of the pinching and conveying path 21 and the third portion 21a). Switching control of the path switching solenoid 25 is performed so that the portion 21 c is connected).

  As described above, by performing the series of deposited banknote distribution processing shown in FIG. 11, the banknotes P to be stored in the banknote storage unit 5 among the banknotes P after being identified by the identification unit 3 are assured It is possible to store in Therefore, it is possible to prevent an unfair process in the deposited bill distributing process.

  In the above embodiment, the pick roller 10 is used as an example of a position changing unit that alternatively changes the relative position between the pick roller 10 and the stacked banknotes PA between the first position and the second position. Although the delivery roller moving part such as the pick roller solenoid 28 which is moved up and down is described as an example, the present invention is not limited to this.

  As another embodiment of the present invention, as shown in FIGS. 12A to 12C, as another example of the position changing portion, the relative position between the pick roller 10 and the stacked banknotes PA is the first position. (That is, as shown in FIG. 12 (c), the position where the pick roller 10 and the stacked banknotes PA can contact) and the second position (ie, as shown in FIG. 12 (a)-(b)) Bottom wall moving part 36 which moves bottom wall 9d of bill insertion part 9 may be used so that it can change between pick roller 10 and stacked bill PA separated).

  In the bill processing apparatus shown in FIG. 12 (a), the bottom wall 9d constituting the bottom of the accommodation space 9a of the bill insertion portion 9 has an opening 9e through which the pick roller 10 can pass. One end of the bottom wall 9d (the end on the back side of the accommodation space 9a) is supported by a horizontally extending pin 9f so that the bottom wall 9d can swing vertically. The other end of the bottom wall 9 d (the end on the deposit port 9 b side) is supported by the bottom wall moving portion 36 from below.

  The pick roller 10 shown in FIG. 12 (a) is rotatably attached to a frame (not shown) or the like of the depositing unit 2 (see FIG. 1) via a rotating shaft extending horizontally so as not to move up and down. There is. The pick roller 10 is disposed at a position where it can pass through an opening 9e formed in the bottom wall 9d when the bottom wall 9d swings up and down with the pin 9f as a rotation center.

  Bottom wall moving unit 36 is configured to be able to move bottom wall 9 d in the vertical direction so that the relative position between pick roller 10 and stacked banknotes PA can be changed between the first position and the second position described above. Have. Specifically, the bottom wall moving unit 36 includes a solenoid 36a, a rod 36b that moves up and down by driving the solenoid 36a, and a contact roller 36c rotatably attached to the tip of the rod 36b. The contact roller 36c is always in contact with the lower surface of the end on the deposit port 9b side of the bottom wall 9d, and supports the bottom wall 9d from below. The drive of the solenoid 36a is controlled by the control unit 27 (see FIGS. 1 and 2), similarly to the pick roller solenoid 28.

  As shown in FIGS. 12A and 12B, when the bottom wall 9d is at the upper position, the pick roller 10 is retracted outside the accommodation space 9a of the stacked bills PA above the bottom wall 9d. . That is, the relative position between the pick roller 10 and the stacked bill PA is a second position in which the pick roller 10 and the stacked bill PA are separated. On the other hand, as shown in FIG. 12C, in the lower position where the bottom wall 9d extends horizontally, the pick roller 10 protrudes into the accommodation space 9a through the opening 9e of the bottom wall 9d to Abuts the lowermost bank note. That is, the relative position between the pick roller 10 and the accumulated bill PA is a first position where the pick roller 10 and the accumulated bill PA can contact.

  In the modification shown in FIGS. 12 (a) to 12 (c), when inserting the stacked bill PA into the accommodation space 9a of the bill insertion portion 9, as shown in FIG. 12 (a), the bottom wall moving portion The rod 36 b and the contact roller 36 c are raised by driving the solenoid 36 a of 36. Thus, the end of the bottom wall 9d on the side of the deposit port 9b is pushed upward by the contact roller 36c, and pivots upward with the pin 9f as the center of rotation. As a result, the pick roller 10 and the stacked banknotes PA are at the second position separated from each other. In this state, since the pick roller 10 is retracted out of the storage space 9a, the stacked banknotes PA can be collectively inserted into the storage space 9a through the deposit port 9b without interfering with the pick roller 10.

  After the stacked banknotes PA are inserted into the storage space 9a, as shown in FIGS. 12A and 12B, in the pressing unit 33, the pressing plate 14 is lowered by the pressing plate moving unit 16 and the pressing plate 14 is used. The stacked bills PA are pressed downward.

  In this modification, the push plate moving unit 16 includes the horizontal plate 37 and a plurality of elastic members 38 such as a spring and rubber so that the push plate 14 can make surface contact with the upper surface of the stacked banknotes PA in the inclined state. Furthermore, it has. The horizontal plate 37 is vertically movably supported by the pair of link arms 16 c and 16 d of the push plate moving unit 16 while maintaining the horizontal posture. That is, the lower end of the link arm 16c is rotatably connected to the push plate 14 with a pin or the like, while the lower end of the link arm 16d is connected to the push plate 14 slidably along the upper surface of the push plate 14. The push plate 14 is connected to the lower surface of the horizontal plate 37 via a plurality of elastic members 38. Therefore, the push plate 14 can change its posture in accordance with the inclination of the upper surface of the stacked banknotes PA together with the elastic deformation of the elastic member 38 by contacting with the stacked stacked banknotes PA. This enables the push plate 14 to make surface contact with the upper surface of the stacked bills PA, regardless of whether the stacked bills PA are horizontal or inclined.

  As shown in FIG. 12C, when the rod 36b and the contact roller 36c of the bottom wall moving part 36 are lowered in a state where the stacked banknotes PA are pressed downward by the push plate 14, they abut on the contact roller 36c. The bottom wall 9d also descends in response to the elastic force of the elastic member 38, the weight of the accumulated bills PA, and the like, and the pick roller 10 protrudes into the housing space 9a through the opening 9e of the bottom wall 9d. As a result, it is possible to change the relative position of the pick roller 10 and the accumulated bill PA to a first position where the pick roller 10 and the accumulated bill PA contact each other. After the change to the first position, the pick roller 10 can feed the bill P of the accumulated bill PA to the delivery port 9c.

  In the modification shown in FIGS. 12 (a) to 12 (c), bottom wall 9d constituting the bottom surface of housing space 9a as a position changing portion for changing the relative position of pick roller 10 and accumulated banknote PA. The bottom wall moving part 36 which moves is used. Therefore, the relative position between the pick roller 10 and the accumulated bill PA is brought into contact with the pick roller 10 and the accumulated bill PA by the vertical movement of the bottom wall 9d on which the accumulated bill PA in the accommodation space 9a is placed. It is possible to easily change between one position (see FIG. 12 (c)) and a second position (see FIG. 12 (b)) in which the pick roller 10 and the stacked bills PA are separated from each other.

In this modification, when the depositing unit stop sensor 17 does not detect a bill P transported by the separation transport unit 32 while the depositing unit drive motor 13 is in operation, the pick roller 10 and the pickup roller 10 are rotated by driving the depositing unit drive motor 13 In order to allow the position relative to the bill PA to alternately change between the first position shown in FIG. 12 (c) and the second position shown in FIG. 12 (b), the bottom wall 9d is The control unit 27 controls the bottom wall moving unit 36 to reciprocate. As shown in FIG. 12 (b), in the second position, the bottom wall 9 d separates the stacked bills PA at a position separated from the pick roller 10. As a result, when the bottom wall 9 d and the stacked banknotes PA placed on the bottom wall 9 d move up and down, it becomes possible for the pick roller 10 in a rotating state to intermittently contact the stacked banknotes PA. As a result, even by the vertical movement of the bottom wall 9d, it becomes possible to perform the loosening retry process similarly to the vertical movement of the pick roller 10 described above, and it is possible to send out the banknote P to the outlet 9c. It is possible to return to the state.

  Moreover, the vertical movement of the bottom wall 9d by the bottom wall moving portion 36 not only causes intermittent contact of the pick roller 10 in a rotating state with the stacked banknotes PA, but also the stacked banknotes PA itself placed on the bottom wall 9d. Since it is possible to shake, it is possible to more effectively break the balance of the stacked bills PA and to smoothly return to the normal bill delivery state.

  Further, in the configuration of the modified example of FIGS. 12A to 12C, since the bottom wall 9d and the stacked banknotes PA move up and down, even if the mechanism for moving the pick roller 10 up and down is omitted, It is possible to change the relative position to the banknote PA.

  Also in the modification of FIG. 12 (a), the control unit 27 sets the first position of the relative position between the pick roller 10 and the accumulated banknote PA by the bottom wall moving unit 36 included in the concept of the position changing unit. After the change between the second position and, more specifically, the reciprocating movement of the bottom wall 9d is performed a predetermined number of times (for example, 10 times), the paper money detecting unit P detects a bill P conveyed by the separation conveyance unit 32. If not, the bottom wall moving unit 36 may be controlled to stop its operation, and the alarm unit 35 may be controlled to emit an alarm. As a result, when the deposit unit stop sensor 17 does not detect the bill P conveyed by the separating / conveying unit 32 after the redrawing process by the vertical movement of the bottom wall 9d, that is, when the return process of the normal bill P can not be resumed. The stop of the reciprocal movement of the bottom wall 9d by the bottom wall moving unit 36 and the alarming by the alarming unit 35 can be performed automatically. Therefore, the worker does not have to monitor or manage the banknote handling apparatus 1 until there is a warning.

  In the present invention, the bottom wall moving part 36 for moving the bottom wall 9 d is a bottom so that it can be changed between the first position where the pick roller 10 and the stacked banknotes PA can contact and the second position where they are separated from each other. It is sufficient that the wall 9d can be moved up and down. Therefore, as shown in FIGS. 12 (a) to 12 (c), the end of the bottom wall 9d is pushed up to swing the bottom wall 9d about the pin 9f as a rotation center, and the bottom wall 9d is vertically maintained with the horizontal posture. It may be configured to move.

  In the above embodiment, as a position changing unit that changes the relative position between the pick roller 10 and the stacked banknotes PA between the first position and the second position, delivery of the pick roller solenoid 28 or the like in FIGS. Although the roller moving part and the example in which the bottom wall moving part 36 of FIG. 12 (a) is used separately are described, the present invention is not limited to this. In the present invention, the position changer may include both the pick roller solenoid 28 and the bottom wall moving portion 36. In this case, the relative position between the pick roller 10 and the stacked banknotes PA is set to the first position and the second position by performing the vertical movement of the pick roller 10 and the vertical movement of the bottom wall 9d on which the stacked banknotes PA are placed. It is possible to change the position quickly and accurately. In addition, when the delivery of the bill to the separating and conveying section is defective, it is possible to quickly carry out the unrolling retry process.

  In the above embodiment, a bill is described as an example of a paper sheet to be processed by the paper sheet processing apparatus, but the present invention is not limited to this, and the invention is not limited to the bill. The sheet processing apparatus according to the present invention can be used for paper sheets such as thin paper sheets which can be accumulated, for example, those made of paper such as postcards and copy paper, and plastic cards, etc. It can be processed by
