  Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[1. First Embodiment]
[1-1. Configuration of banknote dispensing machine]
As shown in a schematic side view in FIG. 1, a banknote dispenser 1 as a medium processing apparatus is installed in, for example, a financial institution or various commercial facilities, and is used by a user (ie, a customer of a financial institution or a commercial facility). In response to the operation, a bill as a medium is withdrawn. The banknote dispensing machine 1 is roughly composed of a lower storage unit 2 and an upper bundle transport unit 3, and further includes a control unit 4 for controlling the whole.

  The control unit 4 is mainly configured by a CPU (Central Processing Unit) (not shown), and by reading and executing a predetermined program from a ROM (Read Only Memory), a flash memory, etc. (not shown) Process. In addition, the control unit 4 includes a storage unit including a RAM (Random Access Memory), a hard disk drive, a flash memory, and the like, and stores various information in the storage unit.

  In the following, the side of the banknote dispenser 1 facing the customer is the front side, the opposite is the rear side, the left and right are the left side and the right side as viewed from the customer facing the front side, and the upper side and the lower side. Is defined and explained.

  In the storage unit 2, a plurality of parts that perform various processing relating to banknotes are incorporated in a rectangular parallelepiped storage housing 10. In the housing case 10, four banknote cassettes 11, a transport unit 13, a discrimination unit 14, a switching unit 15 and a stacking unit 16, and a reject storage 17 are provided.

  Each banknote cassette 11 is comprised by the rectangular parallelepiped shape long in the front-back direction, and each accommodates the banknote of a predetermined denomination inside. Moreover, the banknote cassette 11 has a feeding outlet which feeds banknotes one by one and delivers them to the transport unit 13 on the front side. The conveyance part 13 comprises the conveyance path which is a path | route which conveys a banknote with the roller and belt which are not shown in figure, or the motor which drives these.

  The discrimination unit 14 is in a single-feed state separated one by one and can be withdrawn as a discrimination process for the banknotes being conveyed, or in a double-feed state in which two or more banknotes overlap. It is discriminated whether or not withdrawal is possible, and the discrimination result obtained at this time is supplied to the control unit 4. The control part 4 determines the conveyance destination of each banknote based on the discrimination result supplied from the discrimination part 14. Based on the control of the control unit 4, the switching unit 15 switches the bill conveyance path by changing the inclination angle of a blade (indicated by a triangle in the drawing) that changes the traveling direction by contacting the bill.

  The stacking unit 16 is disposed on the front side of the switching unit 15, and forms a stacking space 16S in which banknotes are stacked. As shown in an enlarged view in FIG. 2A, the stacking unit 16 drives a stage 16T on which bills are stacked and stacked on a mounting surface that is an upper surface in the stacking space 16S. And a stage drive mechanism 16M. As shown in FIG. 2B, the stage driving mechanism 16M as the stage moving unit and the stage attitude changing unit can rotate around a rotation center point 16C provided on the rear side of the stage 16T. Therefore, it can be changed to a stacked posture (FIG. 2A) inclined so as to raise the front end side, or a horizontal posture (FIG. 2B) with the upper surface substantially horizontal. Further, as shown in FIG. 2C, the stage drive mechanism 16M can move the horizontal stage 16T in the vertical direction. For convenience of explanation, the vertical direction, which is the direction that intersects the front-rear direction, is also referred to as a crossing direction below.

  Further, on the upper rear side of the stacking unit 16, a discharge unit 16E that discharges the banknotes conveyed from the switching unit 15 into the stacking space 16S is provided. The stacking unit 16 discharges the banknotes conveyed from the switching unit 15 into the stacking space 16S by the discharge unit 16E, and stacks them in a bundle on the stage 16T. Therefore, hereinafter, the banknotes stacked in this way are also referred to as banknote bundles W. Incidentally, the banknote bundle W is not sealed with a paper band or the like but simply stacked, and therefore may be broken when an external force is applied carelessly.

  An accumulation hole 16 </ b> H (FIG. 1) penetrating in the vertical direction is formed over the accumulation portion 16 over a range corresponding to the accumulation space 16 </ b> S. The accumulation hole 16H also penetrates the upper surface of the storage housing 10 and communicates the accumulation space 16S with the space above the storage housing 10. For this reason, the stacking unit 16 moves the stage 16T upward in a state where banknotes are stacked on the stage 16T (FIG. 2C), thereby collecting the stage 16T and the stacked banknotes (banknote bundle W). It is possible to lift up to the upper side of the upper surface of the storage housing 10, that is, the inside of the bundle transport unit 3.

  The reject storage 17 is arranged on the rear side of the switching unit 15 and is a banknote conveyed from the switching unit 15, that is, a banknote determined by the control unit 4 to be unable to withdraw (hereinafter, this is also referred to as a reject banknote). Or the banknote bundle W falling from the upper bundle conveying unit 3 through the upper intake hole 17H is taken in and stored.

  The bundle conveyance unit 3 as a bundle conveyance unit is formed in a flat rectangular parallelepiped shape that is short in the vertical direction and long in the front-rear direction, and the length in the front-rear direction is longer than that of the storage unit 2. The bundle conveyance unit 3 forms a bundle conveyance path 3Y along the front-rear direction by members such as a conveyance belt and a conveyance guide incorporated therein, and conveys the banknote bundle W along the bundle conveyance path 3Y. (Details will be described later). In addition, a withdrawal port 21 is formed at the front end of the bundle transport housing 20, that is, the front end of the bundle transport path 3Y, as a delivery unit that delivers the banknote bundle W to the user.

  Next, a dispensing operation and a taking-in operation in the banknote dispensing machine 1 will be described. When performing a withdrawal operation, the banknote dispensing machine 1 accepts a withdrawal instruction and a withdrawal amount from a customer via an operation unit (not shown). In response to this, each banknote cassette 11 pays out the denomination and the number of banknotes according to the amount of money to be dispensed one by one from the rear surface, and delivers them to the transport unit 13. The conveyance part 13 conveys each banknote upward, makes the discrimination part 14 discriminate | determine, and makes the control part 4 supply the obtained discrimination result.

  The reject banknote determined to be unable to be withdrawn based on the discrimination result in the control unit 4, that is, cannot be delivered to the user, is transported to the reject storage 17 by the switching unit 15 and stored. Banknotes determined to be able to be withdrawn based on the result of discrimination in the control unit 4, that is, to be delivered to the user, are conveyed to the stacking unit 16 by the switching unit 15.

  The stacking unit 16 sequentially discharges banknotes from the discharge unit 16E in a state where the stage 16T is in the stacking posture (FIG. 2A), and stacks the bills on the rear side of the stage 16T. Eventually, when the stacking unit 16 stacks the denomination and the number of banknotes corresponding to the withdrawal amount, that is, the banknote bundle W, on the stage 16T, the stacking unit 16 rotates the stage 16T and the upper surface thereof is parallel to the transport direction in the bundle transport path 3Y. Then, the banknote bundle W is further moved upward to lift the banknote bundle W into the bundle conveyance path 3Y (FIG. 2C). Subsequently, the banknote dispensing machine 1 advances the banknote bundle W forward in the transport direction along the bundle transport path 3 </ b> Y by the bundle transport unit 3 and transports it to the withdrawal port 21. The bill dispensing machine 1 ends the dispensing operation at this stage, and allows the user to receive the bill bundle W.

  Here, when the banknote bundle W is not taken out from the withdrawal port 21 within a predetermined waiting time, the banknote dispensing machine 1 determines that the user has forgotten to remove the banknote bundle W and starts the taking-in operation. . Specifically, the banknote dispenser 1 takes the banknote bundle W into the bundle transport path 3Y by the bundle transport unit 3 and advances it backward. Eventually, when the banknote bundle W reaches the upper side of the intake hole 17H, the banknote dispenser 1 drops the banknote bundle W from the bundle transport path 3Y and stores it in the reject storage box 17.

  In this way, the banknote dispensing machine 1 forms banknote bundles W by stacking banknotes in the stacking unit 16 and transports them to the front withdrawal port 21 by the bundle transport unit 3 so that the user can receive them. It has become.

[1-2. Configuration of bundle transport unit]
Next, the configuration of the bundle transport unit 3 will be described with reference to FIG. The bundle conveyance unit 3 is mainly composed of an upper conveyance belt 22 and a back plate 51 arranged on the upper side inside the bundle conveyance case 20, and a lower conveyance guide 41 and a lower conveyance belt 42 arranged on the front side below the upper conveyance belt 22. It is comprised by.

  The upper transport belt 22 is an endless belt, and includes a pulley 23 disposed in the vicinity of the rear end of the bundle transport housing 20 and a pulley 24 disposed in the vicinity of the dispensing port 21 positioned at the front end of the bundle transport housing 20. The pulley 25 is stretched around a plurality of pulleys such as a pulley 25 disposed behind the pulley 24. Incidentally, the bundle conveying unit 3 is provided with two upper conveying belts 22 so as to be located at two positions slightly apart in the left-right direction, and the pulleys 23 and the like are also provided at two positions accordingly. Yes.

  The pulley 23 is urged rearward by a spring 31. As a result, the pulley 23 generates a sufficient tension on the upper conveying belt 22. Further, the pulley 23 is rotated by a driving force supplied from a motor (not shown) so that the upper conveyor belt 22 travels.

  The pulley 24 is rotatably attached to the vicinity of the lower end of the arm 32. The arm 32 is inserted into a rotation shaft 33 provided in the vicinity of the upper end, and can rotate freely around the rotation shaft 33. The arm 32 is biased in the direction of the arrow R2 by a spring 34, thereby pressing the pulley 24 provided near the lower end downward.

  The pulley 25 is rotatably attached to the vicinity of the lower end of the arm 35. The arm 35 is generally symmetrical with the arm 32, but is configured to be slightly longer than the arm 32. The arm 35 is inserted into a rotation shaft 36 provided near the upper end, and is freely centered on the rotation shaft 36. Can rotate. The arm 35 is urged in the direction of the arrow R1 by a spring 37, thereby pressing the pulley 25 provided near the lower end downward. Further, the pulley 25 is positioned at a position lower than the height at which the arm 35 is configured to be longer than the arm 32, for example, lower than the height of the upper surface of the stage 16 </ b> T moved upward, that is, lower than the pulley 24. . Thereby, the bundle conveyance path 3 </ b> Y that is the travel path of the banknote bundle W is bent in the vicinity of the pulley 24.

  The lower conveyance guide 41 is provided on the front side of the stage 16T that is lifted up most. The lower conveying guide 41 is formed in a shape that is bent downward in the vicinity of the portion facing the pulley 25, in other words, in a broken line shape when viewed from the left and right directions, although the upper surface of the lower conveying guide 41 is generally flat. Has been. The lower transport guide 41 is configured to slide the banknote bundle W forward or backward along the upper surface thereof. That is, the lower transport guide 41 constitutes a part of the bundle transport path 3Y by its upper surface.

  The lower conveyance belt 42 as the nipping conveyance belt is an endless belt, like the upper conveyance belt 22, and is located at the front end of the bundle conveyance housing 20 and the pulley 43 disposed on the front side of the stage 16 </ b> T lifted upward. A pulley 44 disposed in the vicinity of the dispensing port 21 and a pulley 45 disposed in front of and above the pulley 43 are stretched around the plurality of pulleys.

  The pulleys 43, 44, and 45 are all supported so as to be freely rotatable with respect to the bundle transport housing 20, and their positions are fixed. Further, like the pulley 23, the pulley 43 is configured to run the lower conveyance belt 42 by being supplied with a driving force from a motor (not shown).

  Incidentally, as in the case of the upper transport belt 22, the bundle transport unit 3 is provided with two lower transport belts 42 so as to be located at two positions slightly apart in the left-right direction. A total of two places are provided. The lower conveyance guide 41 is appropriately formed with notches and grooves for avoiding interference with the lower conveyance belt 42.

  The back plate 51 is formed in a thin plate shape that is thin in the front-rear direction and long in the left-right direction, and can be moved forward or backward in the bundle transport unit 3 by a back plate drive mechanism (not shown). The back plate 51 has a flat front surface, and is appropriately provided with a notch (not shown) for avoiding interference with the upper transport belt 22. Further, the lower end of the back plate 51 is located above the upper surface of the stage 16T that has been moved upward, but has a protruding portion that protrudes downward from the upper surface of the stage 16T. Yes. Therefore, a groove (not shown) is provided on the upper surface of the stage 16T and the lower transport guide 41 to avoid interference with the protrusion.

  With this configuration, in the bundle transport unit 3, when the stage 16T on which the banknote bundle W is placed is moved upward and the banknote bundle W reaches the bundle transport path 3Y, the back plate 51 that has been positioned in the rear in advance. Is moved forward, brought into contact with the rear side of the banknote bundle W, and pushed forward. Further, the bundle transport unit 3 circulates the upper transport belt 22 in the direction of the arrow R1 and travels the lower portion thereof forward, and rotates the lower transport belt 42 in the direction of the arrow R2 and travels the upper portion thereof forward. .

  That is, the bundle transport unit 3 sandwiches the banknote bundle W from above and below by the lower part of the upper transport belt 22 and the upper part of the lower transport belt 42 in the bundle transport path 3Y, and the rear side of the banknote bundle W The back plate 51 is brought into contact. In addition, the bundle conveyance unit 3 can convey the banknote bundle W forward by moving the lower part of the upper conveyance belt 22, the upper part of the lower conveyance belt 42, and the back plate 51 forward.

[1-3. Conveying banknote bundles]
Next, conveyance of the banknote bundle W by the bundle conveyance unit 3 will be described. FIG. 4 schematically shows a part of FIG. 3 in an enlarged manner. In the bundle conveyance unit 3, the banknote bundle W is sandwiched between the upper conveyance belt 22 and the lower conveyance belt 42 slightly in front of the stage 16T. Further, the back plate 51 is in contact with the rear side.

  In the bundle transport unit 3, the upper transport belt 22 and the lower transport belt 42 are caused to travel at a predetermined speed V2, and the back plate 51 is moved at a speed V1 that is higher (that is, higher) than the speed V2. For this reason, in the bundle conveyance unit 3, when viewed from the banknote bundle W that is pushed forward from the rear side by the back plate 51 and moves at the speed V1, the upper conveyance belt 22 moves relatively backward in the speed V1-. You are running at V2.

  Further, since the upper conveyor belt 22 is biased downward by a pulley 25 (FIG. 3) slightly behind the front end, the angle θ2 with respect to a virtual straight line LH representing the horizontal direction on the front side of the banknote bundle W. It is stretched forward and downward so as to form Here, if the tension acting on the upper transport belt 22 is T, the downward force N2 applied to the banknote bundle W by the upper transport belt 22 is T · sin θ2.

  By the way, a frictional force is generated between the banknotes constituting the banknote bundle W or between the upper transport belt 22 and the uppermost banknote B1. In particular, in the bundle conveying unit 3, the material selection in the upper conveying belt 22 is made so that the friction coefficient μ2 between the upper conveying belt 22 and the uppermost banknote B1 is larger than the friction coefficient μ1 between the banknotes. And surface processing etc. are done appropriately.

  That is, on the upper surface side of the uppermost banknote B1, a force F2 obtained by multiplying the downward force N2 applied by the upper conveyor belt 22 by the friction coefficient μ2 acts backwardly with the upper conveyor belt 22. On the lower surface side of the uppermost banknote B1, a force F1 obtained by multiplying the downward force N2 by the friction coefficient μ1 acts forwardly between the lowermost banknote located on the lower side.

  For this reason, the force F which is the resultant force of the force F1 and the force F2 acts on the uppermost banknote B1. The force F has a friction coefficient μ2 larger than the friction coefficient μ1 and the forces F1 and F2 are opposite to each other, so that it acts backward, and its value is N2 (μ2−μ1).

  That is, in the bundle conveyance unit 3, during the conveyance of the banknote bundle W, a relatively backward force F is applied to the uppermost banknote B1. For this reason, when the banknote bundle W has a deviation in the state in which the uppermost banknote B1 of the banknote bundle W is projected forward from the other banknotes, the uppermost banknote is transferred during the transport of the banknote bundle W. B1 can be moved backward with respect to other banknotes to reduce the shift width.

[1-4. Effect]
In the above configuration, the bundle transport unit 3 of the banknote dispenser 1 according to the first embodiment is configured to make the speed V1 at which the back plate 51 moves higher than the speed V2 at which the upper transport belt 22 travels ( FIG. 4). Moreover, the bundle conveyance unit 3 made the friction coefficient μ2 between the upper conveyance belt 22 and the banknote larger than the friction coefficient μ1 between the banknotes.

  If the topmost banknote B1 in the banknote bundle W has a deviation so that it jumps out ahead of the other banknotes, the bundle transporting unit 3 moves the topmost banknote B1 while the banknote bundle W is being transported. When the bill is moved backward with respect to the bill, and the rear end of the bill B1 is brought into contact with the front surface of the back plate 51, the backward movement with respect to the other bill is terminated. That is, the bundle transport unit 3 can reduce or eliminate the forward shift amount of the uppermost banknote B1 only by transporting the banknote bundle W forward.

  Further, the bundle transport unit 3 also moves backward from the banknote adjacent to the upper side when the second banknote or less from the top of the banknote bundle W has a deviation in a state of jumping forward from the other banknotes. Since the force is received, it can be moved backward with respect to the lower banknote, and the shift amount can be reduced or the shift can be eliminated.

  In particular, when the banknote dispensing machine 1 generates the banknote bundle W in the stacking unit 16, the banknotes are discharged and stacked from the discharge unit 16 </ b> E with the stage 16 </ b> T in the stacking posture (FIG. 2A) to form the banknote bundle W. . At this time, the stacking unit 16 tilts the stage 16T with respect to the horizontal direction, and the tongue pieces incorporated in the discharge unit 16E draw each banknote backward. Are collected with almost no deviation.

  Subsequently, the stacking unit 16 sets the stage 16T in a horizontal posture (FIG. 2B) and then moves it upward (FIG. 2C), thereby transferring the banknote bundle W to the bundle transport path 3Y in the bundle transport unit 3. To reach. Here, when the stacking unit 16 switches the stage 16T from the stacking posture to the horizontal posture, the stage driving mechanism 16M rotates the stage 16T and the loaded banknote bundle W around the rotation center point 16C. At this time, in the banknote bundle W, centrifugal force about the rotation center point 16C acts, so that the number of banknotes located on the upper side, that is, the other banknotes on the upper side is small, and between the adjacent banknotes. A bill having a comparatively small frictional force acting on is shifted in a direction away from the rotation center point 16C, that is, forward.

  On the other hand, even if the bundle conveying unit 3 has a deviation in a state where the upper banknotes are protruded forward in the banknote bundle W, while being conveyed forward, that is, until withdrawing from the dispensing port 21. In the meantime, the amount of deviation can be reduced or the deviation can be eliminated.

  By the way, in the bundle conveyance unit 3, if the pulley 25 (FIG. 3) is positioned so as to be in contact with the upper surface of the stage 16T, that is, at the same height as the pulley 24, the upper conveyance belt 22 is shown in FIG. Travel along a route as shown by the straight line L1. In this case, when the angle of the straight line L1 with respect to the virtual straight line LH is θ1, the force N1 acting downward on the banknote bundle W is T · sin θ1. As can be seen from FIG. 4, since the angle θ1 <the angle θ2, the force N1 (= T · sin θ1) is smaller than the force N2 (= T · sin θ2).

  That is, in the bundle transport unit 3, the force acting on the banknote bundle W by deliberately positioning the pulley 25 at a position lower than the height of contact with the upper surface of the stage 16 </ b> T moved upward, that is, below the pulley 24. N2 can be made sufficiently large, and the force F acting on the uppermost banknote B1 can also be made sufficiently large.

  From another point of view, the bundle conveying unit 3 has a speed V1 for moving the back plate 51 larger than a speed V2 at which the upper conveying belt 22 travels, and a pulley compared to a conventional bundle conveying unit. The shift of the uppermost banknote B1 in the banknote bundle W can be reduced or eliminated simply by positioning 25 slightly below. Therefore, the bundle transport unit 3 only needs to make a slight design change or set speed change without adding complicated parts or the like as compared with the conventional configuration. There is no need for time to stop.

  According to the above configuration, the bundle transport unit 3 of the banknote dispenser 1 according to the first embodiment increases the speed V1 at which the back plate 51 moves than the speed V2 at which the upper transport belt 22 travels, The friction coefficient μ2 between the upper conveyance belt 22 and the banknotes was made larger than the friction coefficient μ1 between the banknotes. If the topmost banknote B1 in the banknote bundle W has a deviation so that it jumps out ahead of the other banknotes, the bundle transporting unit 3 moves the topmost banknote B1 while the banknote bundle W is being transported. Move backward with respect to the bill. Thereby, the bundle conveyance unit 3 can reduce or eliminate the forward shift amount of the uppermost banknote B1 only by conveying the banknote bundle W forward.

[2. Second Embodiment]
The banknote dispensing machine 101 (FIG. 1) according to the second embodiment is different from the banknote dispensing machine 1 according to the first embodiment in that it includes a bundle conveyance unit 103 that replaces the bundle conveyance unit 3. However, the other points are similarly configured.

  As shown in FIG. 5 corresponding to FIG. 3, the bundle conveying unit 103 is different from the bundle conveying unit 3 in that the pulley 125, the arm 135, the rotation instead of the pulley 25, the arm 35, the rotation shaft 36 and the spring 37. The difference is that the shaft 136 and the spring 137 are provided. The bundle conveyance unit 103 is different in that it has a lower conveyance guide 141 that replaces the lower conveyance guide 41 and a pulley 146, and a bundle conveyance path 103Y that replaces the bundle conveyance path 3Y. About the point, it is comprised in general similarly.

  The rotation shaft 136 is located behind the rotation shaft 36. The arm 135 is shorter than the arm 35 and has the same length as the arm 32. Although both the pulley 125 and the spring 137 are configured in the same manner as the pulley 25 and the spring 37, the pulley 125 and the spring 137 are provided at different positions from the pulley 25 and the spring 37 according to the configurations of the rotating shaft 136 and the arm 135. ing. Specifically, the pulley 125 is high enough to contact the upper surface of the stage 16T moved upward, and is located at the same height as the pulley 24 near the front end. That is, the pulley 125 is located above and behind the pulley 25. For this reason, the bundle conveyance path 103Y is not bent in the vicinity of the pulley 125, but is formed in a substantially linear shape along the front-rear direction.

  Unlike the lower conveyance guide 41, the lower conveyance guide 141 is not bent at a position directly below the pulley 125, and its upper surface is formed to be substantially flat. Incidentally, similarly to the lower conveyance guide 41, the lower conveyance guide 141 is appropriately configured with notches and grooves (not shown) for avoiding interference with the lower conveyance belt 42 and the protrusions provided on the back plate 51. Yes.

  The pulley 146 has a height substantially equal to that of the pulleys 44 and 45 and is located at a position almost directly below the pulley 125. Similar to the pulleys 43, 44, and 45, the pulley 146 is supported so as to be freely rotatable with respect to the bundle transport housing 20, and its position is fixed.

  The bundle conveyance unit 103 causes the upper conveyance belt 22 to travel at a speed V2 as well as the bundle conveyance unit 3 according to the first embodiment, and the back plate 51 has a speed V1 larger (that is, higher) than the speed V2. (Fig. 4).

  In this way, the bundle conveying unit 103 has a pulley 125 positioned above and behind the pulley 25 as compared to the bundle conveying unit 3 (FIG. 3). Is substantially the same as the angle θ2 (FIG. 4) in the first embodiment. The bundle conveyance unit 103 causes the upper conveyance belt 22 to travel at the speed V2 and moves the back plate 51 at the speed V1.

  For this reason, in the bundle conveyance unit 103, as in the first embodiment, a force N2 equivalent to that in the first embodiment can be applied downward from the upper conveyance belt 22 to the banknote bundle W, A backward force F = N2 (μ2−μ1) can be applied to the uppermost banknote B1 in the banknote bundle W (FIG. 4).

  Thereby, the bundle conveyance unit 103, like the first embodiment, has a deviation such that the uppermost banknote B1 in the banknote bundle W protrudes forward from the other banknotes. During conveyance, the uppermost banknote B1 can be moved backward relative to other banknotes, and the amount of deviation can be reduced or eliminated.

  In particular, in the bundle transport unit 103, since the upper surface of the lower transport guide 141 is formed flat without being bent, the banknote bundle W can be linearly advanced along the front-rear direction. Can be transported.

  In other respects, the bundle conveyance unit 103 according to the second embodiment can achieve the same effects as the bundle conveyance unit 3 according to the first embodiment.

  According to the above configuration, the bundle conveying unit 103 of the banknote dispensing machine 101 according to the second embodiment is configured so that the pulley 125 has a height equivalent to that of the pulley 24 and is arranged relatively rearward so that the upper conveying belt. The front part of the banknote bundle W in 22 is inclined at an angle equivalent to that of the first embodiment. Thereby, the bundle conveyance unit 103 can move the uppermost banknote B1 backward relative to the other banknotes during the conveyance of the banknote bundle W, and forward the other banknotes, as in the first embodiment. The amount of deviation can be reduced or eliminated.

[3. Third Embodiment]
Compared with the banknote dispensing machine 1 according to the first embodiment, the banknote dispensing machine 201 (FIG. 1) according to the third embodiment is a bundle that replaces the bundle transport unit 3, the stacking unit 16, and the control unit 4. Although different in that it includes the transport unit 203, the stacking unit 216, and the control unit 204, other points are configured similarly.

  Similar to the control unit 4 according to the first embodiment, the control unit 204 is mainly configured by a CPU (not shown). By reading and executing a predetermined program from a ROM, flash memory, or the like (not shown), a withdrawal is performed. Processing such as processing is performed. At this time, the control unit 204 executes a part of processing different from that of the control unit 4 (details will be described later).

[3-1. Configuration of bundle transport unit]
The bundle conveyance unit 203 has pulleys 243 and 245 instead of the pulleys 43 and 45 as compared with the bundle conveyance unit 3 (FIG. 3) according to the first embodiment, and a bundle conveyance path instead of the bundle conveyance path 3Y. It is different in that 203Y is formed. The bundle conveying unit 203 includes a receiving plate 261, a rotating base 262, a rotating shaft 263, a roller 264, a spring 265, and a stopper 266, and a bundle instead of the bundle conveying housing 20 according to this. Although different in that it has the transport housing 220, other points are configured in the same manner.

  The receiving plate 261 is formed in a plate shape that is thin in the front-rear direction and long in the left-right direction, and is positioned so as to cross the bundle conveyance path 203Y in the left-right direction. Incidentally, the receiving plate 261 is appropriately provided with a notch or the like so as to avoid interference with the upper conveyance belt 22 and the lower conveyance belt 42. The lower conveyance guide 41 is appropriately formed with a hole (not shown) elongated in the left-right direction so as to avoid interference with the receiving plate 261.

  The rotating base 262 is formed in a shape similar to the capital letter “L” when viewed from the left-right direction, with the bent portion facing rearward and both ends positioned vertically on the front side. The rotating base 262 is fixed to the bundle conveying housing 220 at the bent portion, and is inserted into a rotating shaft 263 along the left-right direction, and is supported rotatably by the rotating shaft 263.

  In addition, the rotating base 262 has the above-described receiving plate 261 attached to the upper end portion and a roller 264 attached to the lower end portion. The roller 264 is formed in a cylindrical shape with the central axis extending in the left-right direction, and is rotatably supported by the rotating base 262. Incidentally, the position of the roller 264 in the left-right direction is equal to the left end surface of the stage 16T in the stacking unit 216. Further, the positions of the rotating base 262 and the rotating shaft 263 in the left-right direction are on the left side of the roller 264.

  Further, the rotation base 262 is biased in the direction of the arrow R1 that is clockwise in the drawing by incorporating the spring 265. Therefore, unless the external force is particularly applied, the rotating base 262 is rotated in the direction of the arrow R1 by the action of the spring 265, and is stationary with a part of the rotating base 262 contacting the stopper 266. At this time, the receiving plate 261 is positioned so as to cross the bundle conveyance path 203Y in the left-right direction as described above. Hereinafter, such a posture of the rotating base 262 is referred to as a receiving posture.

  Further, for example, when a downward or rearward force is applied to the roller 264, the rotating base 262 rotates in the direction of arrow R2 as shown in FIG. 7 corresponding to FIG. It is moved below the bundle conveyance path 203Y, that is, outside the bundle conveyance path 203Y. Hereinafter, such a posture of the rotating base 262 is referred to as a retracted posture.

  As described above, the receiving plate 261 is positioned inside the bundle conveyance path 203 </ b> Y when the rotating base 262 rotates around the rotating shaft 263 and transitions to the receiving position or the retracted position, or the bundle It is evacuated to the outside of the conveyance path 203Y. For convenience of explanation, the rotating base 262, the rotating shaft 263, the roller 264, and the spring 265 are collectively referred to as a receiving plate moving unit.

  As shown in FIG. 6, the stacking unit 216 is different from the stacking unit 16 (FIG. 2) according to the first embodiment in that an interlocking arm 216A is attached to the stage 16T. The points are similarly configured. The interlocking arm 216A is formed in a plate shape that is long in the front-rear direction and thin in the left-right direction, and a part of the front lower side is cut off in a rectangular shape.

  Incidentally, the interlocking arm 216A is attached to the left end of the stage 16T, the banknote bundle W transported through the upper transport belt 22 and the lower transport guide 41 of the bundle transport unit 203, and the bundle transport path 203Y, and further, the rotating base 262. In addition, it does not interfere with the rotation shaft 263 and the like, but can come into contact with the roller 264. For convenience of explanation, hereinafter, the rotation base 262, the rotation shaft 263, the roller 264, the spring 265, and the interlocking arm 216A are collectively referred to as a stage interlocking unit.

  Further, in the bundle conveyance unit 203, unlike the first and second embodiments, the speed at which the upper conveyance belt 22 and the lower conveyance belt 42 travel and the speed at which the back plate 51 moves are equal to each other. .

[3-2. Conveying banknote bundles]
Next, the conveyance of the banknote bundle W by the bundle conveyance unit 203 will be described including the accumulation of banknotes in the accumulation unit 216. As in the first embodiment, the control unit 204 (FIG. 1) transports the banknotes fed out from the banknote cassette 11 by the transport unit 13, discriminates them by the discrimination unit 14, and determines the banknotes that can be withdrawn. It is transported to the stacking unit 216 by the switching unit 15.

  The stacking unit 216 (FIG. 6), like the stacking unit 16 (FIG. 2) in the first embodiment, sequentially discharges banknotes from the discharge unit 16E in a state where the stage 16T is in the stacking posture, and on the stage 16T. Accumulate in the rear part. At this time, the interlocking arm 216A is positioned far above the roller 264 and does not apply any external force to the roller 264. For this reason, the rotating base 262 becomes a receiving posture by the action of the spring 265, and the receiving plate 261 is positioned inside the bundle conveying path 203Y.

  Eventually, when the stacking unit 216 stacks the denomination and number of banknotes corresponding to the withdrawal amount, that is, the banknote bundle W, on the stage 16T, as shown in FIG. . At this time, the interlocking arm 216A comes into contact with the roller 264 in the middle of rotation, and moves backward and downward while pushing down the roller 264. As a result, the rotating base 262 rotates in the direction of the arrow R2 to the retracted position, and moves the receiving plate 261 to the outside of the bundle conveying path 203Y.

  Subsequently, the stacking unit 216 moves the banknote bundle W into the bundle transport path 203Y as shown in FIG. 8 by raising the stage 16T by the stage drive mechanism 16M. At this time, the interlocking arm 216A moves away from the roller 264 because it moves upward again. As a result, the rotating base 262 is again in the receiving posture by the action of the spring 265, and the receiving plate 261 is positioned inside the bundle conveying path 203Y.

  In this state, the control unit 204 controls the bundle conveyance unit 203 to move the back plate 51 forward and contact the back side of the banknote bundle W, and then the upper conveyance belt 22 and the lower conveyance belt 42. The bill bundle W is transported forward by starting the travel of.

  Eventually, as shown in FIG. 9, the control unit 204 detects that the front end of the banknote bundle W has come into contact with the receiving plate 261 by a predetermined sensor (not shown). At this time, the banknote bundle W is sandwiched between the receiving plate 261 and the back plate 51 from the front and rear. Subsequently, the control unit 204 temporarily stops the movement of the back plate 51 and the traveling of the upper conveyance belt 22 and the lower conveyance belt 42, and controls the stacking unit 216 to lower the stage 16T as shown in FIG.

  At this time, similarly to the case shown in FIG. 7, the interlocking arm 216 </ b> A abuts on the roller 264 in the middle of rotation, and moves backward and downward while pushing down the roller 264. As a result, the rotating base 262 rotates in the direction of the arrow R2 to the retracted position, and moves the receiving plate 261 to the outside of the bundle conveying path 203Y. Thereby, the banknote bundle W can advance forward. Thereafter, the control unit 204 resumes the movement of the back plate 51 and the traveling of the upper conveyance belt 22 and the lower conveyance belt 42, and eventually causes the banknote bundle W to reach the dispensing port 21.

[3-3. Effect]
In the above configuration, the banknote dispensing machine 201 according to the third embodiment has the interlocking arm 216A attached to the stage 16T of the stacking unit 216. In addition, the bundle transport unit 203 of the banknote dispenser 201 has a receiving plate 261 attached to one end of a rotating base 262 that rotates about a rotating shaft 263, and the receiving base 262 rotates as the rotating base 262 rotates. The stop plate 261 is moved to the inside or outside of the bundle conveyance path 203Y.

  When the banknote dispensing machine 201 generates the banknote bundle W by the stacking unit 216 and raises the stage 16T, the banking machine 216A is separated from the roller 264 attached to the rotating base 262, and the rotating base is rotated. Then, the receiving posture is set, and the receiving plate 261 is positioned inside the bundle conveying path 203Y (FIG. 8).

  In this state, the bundle transport unit 203 moves the back plate 51 forward and causes the upper transport belt 22 and the lower transport belt 42 to travel forward to transport the banknote bundle W forward. Eventually, the bundle transport unit 203 puts the banknote bundle W between the front and rear when the front end of the banknote bundle W comes into contact with the reception board 261. Thereby, even if some banknotes of the banknote bundle W have misalignment in the front-rear direction, the bundle transport unit 203 can eliminate this misalignment and align the stacks in an orderly manner.

  In particular, the bundle transport unit 203 sandwiches all banknotes constituting the banknote bundle W from the uppermost surface to the lowermost surface between the receiving plate 261 and the back plate 51. Therefore, unlike the first and second embodiments, the bundle transport unit 203 has not only the uppermost surface in the banknote bundle W and the vicinity thereof, but also the banknotes at the front, the middle, the lowermost surface, and the vicinity thereof. Even if it is shifted in the state of jumping out, it is possible to reliably correct this shift and accumulate it in an orderly manner.

  Further, the bundle transport unit 203 causes the roller 264 provided on the rotating base 262 to abut on the interlocking arm 216A provided on the stage 16T, and rotates the rotating base 262 as the stage 16T moves in the vertical direction. Thus, the receiving plate 261 is moved to the inside or outside of the bundle conveying path 203Y (FIGS. 7, 8, and 10). For this reason, the bundle transport unit 203 does not need to separately provide a driving force source (that is, a motor or the like) for rotating the rotating base 262, and can effectively suppress an increase in the number of parts and a complicated configuration.

  According to the above configuration, the banknote dispenser 201 according to the third embodiment moves the receiving plate 261 to the inside or the outside of the bundle conveyance path 203Y in conjunction with the movement of the stage 16T in the vertical direction. I made it. The bundle transport unit 203 raises the stage 16T on which the banknote bundle W is placed, and then moves the back plate 51 forward and runs the upper conveyor belt 22 and the lower conveyor belt 42 forward to move the front end of the banknote bundle W. Is in a state where the banknote bundle W is sandwiched from the front and rear by the receiving plate 261 and the back plate 51. Thereby, even if some banknotes of the banknote bundle W have misalignment in the front-rear direction, the bundle transport unit 203 can eliminate this misalignment and align the stacks in an orderly manner.

[4. Other Embodiments]
In the first embodiment described above, by providing the pulley 25 at a position lower than the pulley 24, the inclination angle of the upper transport belt 22 with respect to the horizontal direction on the front side of the banknote bundle W is set to a relatively large angle θ2. The case was described (FIG. 4). However, the present invention is not limited to this. For example, when the inclination angle of the upper conveying belt 22 is the angle θ1, the sufficient force F is applied to the uppermost banknote B1 even when the downward force N1 = T · sin θ1. The pulley 25 may be provided at the same height as the pulley 24. In this case, the bundle conveyance path 3Y can be formed linearly without being bent in the vicinity of the pulley 24.

The case of letting it was described. However, the present invention is not limited to this. For example, the speed V2 and the speed V1 may be appropriately changed according to the number of banknote bundles W and the denomination of banknotes. For example, when the number of banknote bundles W is relatively large, it is assumed that the amount of deviation of the uppermost banknote B1 is relatively large. Therefore, the speed difference between the speed V2 and the speed V1 may be increased. The same applies to the second embodiment.

  Furthermore, in the first embodiment described above, when the banknote bundle W is transported forward along the bundle transport path 3Y, the upper transport belt 22 and the lower transport belt 42 are moved forward at a speed V2, The case where the back plate 51 is caused to travel forward at a speed V1 larger than this has been described. However, the present invention is not limited to this. For example, when the banknote bundle W that the user has forgotten to remove from the withdrawal port 21 is taken in and the banknote bundle W is conveyed backward, the upper conveyance belt 22 and the lower conveyance belt 42 are used. The back plate 51 that is moved backward at a predetermined speed and that is positioned on the front side of the banknote bundle W may be moved backward at a higher speed.

  Further, in the first embodiment described above, in the stacking unit 16, when the banknotes are discharged from the discharge unit 16E, the stage 16T is inclined and stacked (FIG. 2A), and the banknote bundle W is moved in the vertical direction. A case has been described in which the stage 16T is brought to a substantially horizontal conveying posture when it is moved (FIGS. 2B and 2C). However, the present invention is not limited to this. For example, the stage 16T may be in the transport posture when the banknotes are discharged from the discharge unit 16E. The same applies to the second and third embodiments.

  Further, in the first embodiment described above, the case has been described in which the posture is changed by rotating the stage 16T around the rotation center point 16C provided on the rear side of the stage 16T. However, the present invention is not limited to this. For example, a rotation center point 16C may be disposed on the front side of the stage 16T, and the stage 16T may be rotated about the rotation center point 16C. The same applies to the second and third embodiments.

  Further, in the first embodiment described above, the stacking unit 16 is disposed on the front side of the switching unit 15 in the storage unit 2 (FIG. 1), and the reject storage 17 is disposed on the rear side of the switching unit 15.

  Furthermore, in the third embodiment described above, the interlocking arm 216A, the rotating base 262, and the like are interlocked so that the receiving plate 261 is moved inside the bundle conveying path 203Y in conjunction with the vertical movement of the stage 16T. Or the case where it moves outside was described. However, the present invention is not limited to this. For example, by providing a dedicated driving force source (that is, a motor or the like), the receiving plate 261 is moved inside or outside the bundle conveying path 203Y regardless of the movement of the stage 16T. Anyway.

  Furthermore, in 1st Embodiment mentioned above, the case where this invention was applied to the bundle conveyance unit 3 which conveys the banknote bundle W substantially along the front-back direction was described. However, the present invention is not limited to this, and the present invention may be applied to a bundle transport unit that transports the banknote bundle W along other directions such as an oblique direction and a vertical direction. The same applies to the second and third embodiments.

  Furthermore, in 1st Embodiment mentioned above, in the banknote dispensing machine 1 which withdraws the banknote as a medium according to a user's operation, this is carried out to the bundle conveyance unit 3 which conveys the banknote bundle W as a medium bundle.
