When the change is paid out, a predetermined amount of banknotes is carried out from the storage 16 storing the thousand yen bills and the five thousand yen bills, and is dispensed from the withdrawal port 12.

  The banknote processing apparatus 10 having such a configuration is mounted together with a coin processing apparatus and the like for performing coin deposit / withdrawal processing, and a money processing machine connected to a higher-level model such as POS (Point Of Sales) is configured. The Moreover, although this Embodiment demonstrates the banknote processing apparatus 10 which makes the object of carrying out and accommodation the banknote, it is possible to process similarly also about paper sheets, such as a securities | separation.

Next, the storage 16 of the banknote handling apparatus 10 having the above configuration will be described.
FIG. 2 is a side view of the storage when the embodiment is not operating.
The storage 16 has a storage portion 20 surrounded by a side plate 21a and first and second transport guides 21b and 21c, and the transport path 13 is integrally connected to the first and second transport guides 21b and 21c. And communicated with the storage unit 20. In addition, the arrow Xo in FIG. 2 represents the carrying-out direction, and the arrow Xi represents the storing direction.

  The storage unit 20 is provided with a stage 22 on which banknotes BNs in which a plurality of banknotes BN are stacked are placed. The stage 22 is moved toward and away from the first transport guide 21b by pressing means such as a panda graph (not shown) disposed at the lower part of the stage 22.

  In addition, the first conveyance guide 21b is provided with pulleys 23 and 24, a conveyance belt 25 wound around both sides of the pulleys 23 and 24, and a conveyance roller 27. In addition, the conveyance surface of the conveyance belt 25 faces the storage unit 20 side or the conveyance path 13 side, and a part of the outer peripheral surface of the conveyance roller 27 is exposed. In the second conveyance guide 21c, a separation roller 26 and a driven roller 28 are disposed on the conveyance path 13 side with a part of the outer peripheral surface exposed.

  The pulley 23 is pivotally supported by the shaft 23a on the first transport guide 21b so as to press the central portion of the main surface of the uppermost banknote BN1 of the banknote BNs by the moving stage 22, and according to the transport direction of the banknote BN. And is configured to be rotatable in a clockwise direction and a counterclockwise direction.

  The pulley 24 is separated from the pulley 23 in the unloading direction side, is supported by the shaft 24a on the first transport guide 21b, and can be rotated clockwise and counterclockwise depending on the transport direction of the banknote BN. It is configured.

A drive mechanism such as a motor is connected to both or one of the pulleys 23 and 24, and the drive mechanism rotates the pulleys 23 and 24 in a predetermined transport direction.
The conveyor belt 25 is, for example, an annular shape, and is wound around both sides of the pulleys 23 and 24, extended in the carry-out direction side, and provided with tension (wound). The transport surface of the transport belt 25 wound in this way is opposed to the storage unit 20 side or the transport path 13 side. The conveyance belt 25 rotates in accordance with the rotational drive of the pulleys 23 and 24, and the conveyance surface can travel in the carry-out direction and the storage direction. Details of the operation of the conveyor belt 25 by the pulleys 23 and 24 will be described later.

  The separation roller 26 is arranged to be opposed to the conveyance surface of the conveyance belt 25 so as to press and distort the conveyance surface of the conveyance belt 25 vertically upward in FIG. 2, and is supported by the second conveyance guide 21c on the shaft 26a. Thus, it is configured to be able to rotate counterclockwise on the storage direction side. A high friction member 26 b is disposed on the outer peripheral surface of the separation roller 26. A pair of separation rollers 26 are arranged at an appropriate constant interval so as not to cause skew or damage to the banknote BN1 in a normal transport operation. Such a pair of separation rollers 26 rotates the counterclockwise direction on the banknote BN1 fed out by the conveyor belt 25 and applies friction to the storage direction side. Further, the banknote BN1 inserted from the deposit port 11 or conveyed from the other storage 16 or the like rotates counterclockwise and gives friction to the storage direction side. The separation roller 26 is connected to a drive mechanism, and the drive mechanism rotates the separation roller 26 in the counterclockwise direction. Alternatively, the separation roller 26 may be driven to rotate in the counterclockwise direction by being connected to a drive mechanism that rotationally drives the pulleys 23 and 24 by a transmission mechanism such as another pulley. Details of the separation roller 26 will be described later.

  The transport roller 27 is further separated from the arrangement position of the pulley 24 toward the unloading direction side, and is supported by the first transport guide 21b and supported by the shaft 27a so as to be able to rotate in the clockwise direction and the counterclockwise direction together with the pulleys 23 and 24. It is configured. A pair of the transport rollers 27 are also arranged at an appropriate constant interval so as not to cause skew or damage to the banknote BN1 by a normal transport operation. Such a pair of transport rollers 27 transports the banknote BN1 fed from the transport belt 25 in a counterclockwise direction together with the pulleys 23 and 24. Further, the banknote BN1 inserted from the deposit port 11 or conveyed from the other storage 16 or the like is rotated in the clockwise direction together with the pulleys 23 and 24 and stored in the storage unit 20. The transport roller 27 is connected to a drive mechanism and is driven to rotate in a predetermined transport direction by the drive mechanism.

  The driven roller 28 is disposed to face the pair of transport rollers 27 so as to be in contact with the second transport guide 27 c, supported by the shaft 28 a on the second transport guide 21 c, and driven by the rotation of the transport roller 27 to rotate clockwise and counterclockwise. It is configured to be rotatable. A pair of driven rollers 28 are also arranged at an appropriate constant interval so as not to cause skew or damage to the banknote BN1 in a normal transport operation. Such a pair of driven rollers 28 follows the conveyance roller 27 to rotate and carry out the banknote BN1 fed out by the conveyance belt 25. Further, the banknote BN1 inserted from the deposit port 11 or conveyed from another storage 16 or the like is rotated in the counterclockwise direction following the conveyance roller 27 and stored in the storage unit 20.

  Further, the presser member 29 is swingably disposed on the first conveyance guide 21b, retracts and approaches the stage 22, and the main surface of the uppermost banknote BN1 of the banknote BNs on the stage 22 is placed on the stage by its own weight. Press to the 22 side.

  The carry-out operation and storage operation of the banknote BN1 in the storage 16 having such a configuration will be described. In the storage 16 having the above-described configuration, for example, a pressing unit that moves the stage 22 and each roller are rotationally driven by a control unit (not shown) disposed in the storage 16 based on a command from a higher-level model. The operation of the driving mechanism and the pressing member 29 are controlled to carry out or store the banknote BN1.

  First, carry-out of the banknote BN1 from the storage case 16 will be described. As described above, the banknote BN1 is the uppermost banknote BN of the banknote BNs, and the banknote BN2 represents the banknote BN below the banknote BN1.

  3, 4, and 6 are side views of the storage case of FIG. 2 for explaining the banknote carry-out operation, and FIG. 5 is a diagram of FIG. It is a side enlarged view of a storage. 4 to 6, the pressing member 29 remains retracted to the first conveyance guide 21b side, and the description thereof is omitted. FIG. 5 shows an enlarged view of the pulley 24, the conveyance belt 25 and the separation roller 26.

  The main surface of the uppermost banknote BN1 of the banknote BNs placed on the stage 22 that is moved by the driving of the pressing means (not shown) is wound because the transport surface of the transport belt 25 is distorted by the separation roller 26. It is brought into pressure contact with the pulley 23 side of the laid conveyor belt 25. Further, the stage 22 approaches the first conveyance guide 21b, and the pressing member 29 is retracted to the first conveyance guide 21b side. Thereafter, the presser member 29 remains retracted to the first transport guide 21b until the banknote BN1 is unloaded from the transport path 13 (FIG. 3).

  In the state shown in FIG. 3, the pulleys 23 and 24, the separation roller 26, and the transport roller 27 are rotated in the counterclockwise direction (solid arrow direction) in FIG. As the pulleys 23 and 24 are driven to rotate, the conveying surface of the conveying belt 25 travels in the unloading direction (solid arrow direction) in FIG. The driven roller 28 that is in circumferential contact with the conveying roller 27 is rotated in the clockwise direction (indicated by the broken line arrow) in FIG. 4 following the rotation of the conveying roller 27 in the counterclockwise direction.

  At this time, the uppermost banknote BN1 of the banknote BNs receives a frictional force from the transport surface of the transport belt 25 running in the carry-out direction in FIG. 4 and is fed out in the carry-out direction in FIG. Further, due to the frictional force from the fed banknote BN1, a plurality of banknotes BN equal to or less than the banknote BN2 are bundled and conveyed together in the carry-out direction by the frictional force generated between them. The bundled banknotes BN enters the gap (contact portion) between the transport belt 25 and the separation roller 26 with the banknote BN1 at the head (FIG. 4).

  The main surface of the banknote BN1 that has entered the contact portion between the separation roller 26 and the conveyance belt 25 that has been pressed and distorted by the separation roller 26 is transferred from the conveyance surface of the conveyance belt 25 that travels in the conveyance direction in FIG. Receives frictional force f1. The wound conveyor belt 25 can reliably apply the frictional force f1 to the banknote BN1 by the pressure from the separation roller 26 and the tension of the conveyor surface.

  On the other hand, the back surface of the banknote BN1 receives a frictional force f2 from the separating roller 26 rotating in the counterclockwise direction in FIG. At this time, if the frictional force f1 is set to be larger than the frictional force f2, only the banknote BN1 is separated from the other banknotes BNs, and the contact portion between the transport belt 25 and the separation roller 26 is transported in the unloading direction. The Moreover, since banknote BNs below banknote BN2 is conveyed by the rotating separation roller 26 to the accommodation direction side, conveyance to a contact part is prevented. In this way, only one banknote BN1 separated from the banknote BNs is conveyed to the carry-out direction side. In order to make the frictional force f1 larger than the frictional force f2, for example, the friction coefficient of the conveying belt 25 is made larger than that of the high friction member 26b, or the traveling speed of the conveying belt 25 is made faster than that of the separation roller 26. (FIG. 5).

  The banknote BN1 thus transported through the contact portion between the transport belt 25 and the separation roller 26 and separated into one sheet is subjected to frictional force by the transport surface of the transport belt 25 traveling in the carry-out direction, and the transport roller 27 and the follower are driven. The roller 28 is conveyed to a circumferential contact portion that is circumferentially contacted (FIG. 6).

  When the banknote BN1 enters the circumferential contact portion of the transport roller 27 and the driven roller 28, the pulleys 23 and 24 stop rotating. The banknote BN1 is carried out so as to be pulled out by receiving a frictional force from the conveying roller 27 rotating in the counterclockwise direction and the driven roller 28 rotating in the clockwise direction following the conveying roller 27. At this time, the pulleys 23 and 24 are stopped from rotating and the conveyance belt 25 is also stopped. Therefore, even if the banknote BN2 receives a frictional force in the carry-out direction from the banknote BN1, the banknote BN2 is restrained from the transport belt 25 and receives a larger frictional force in the storing direction. Is prevented.

Thus, the banknote BN1 carried out from the storage 16 passes through the transport path 13 and is transported to the withdrawal port 12, the collection box 17, or the like.
Next, storage of the banknote BN1 in the storage 16 will be described.

7 to 9 are side views of the storage shown in FIG. 2 for explaining the storing operation of banknotes.
The banknote BN1 when it is inserted from the deposit port 11 or transferred from another storage 16 is transported through the transport path 13 and stored in the storage 16.

  When the banknote BN1 is stored in the storage case 16, the stage 22 on which the banknote BNs is placed is retracted from the first transport guide 21b, and this state is maintained, so that the storage space for the stored banknote BN1 is increased. Secure. The pulleys 23 and 24 and the conveyance roller 27 are rotated in the clockwise direction (broken arrow direction) in FIG. At this time, the conveyance surface of the conveyance belt 25 travels in the direction of the broken line arrow in FIG. Further, the driven roller 28 that is in contact with the conveying roller 27 rotates in the counterclockwise direction (solid arrow direction) in FIG. 7 following the clockwise rotation of the conveying roller 27. The separation roller 26 rotates counterclockwise in FIG. 7 (solid arrow direction) in the same manner as when the banknote BN1 is carried out.

In this state, the banknote BN1 is transported through the transport path 13 and reaches the circumferential contact portion where the transport roller 27 and the driven roller 28 are in circumferential contact (FIG. 7).
The banknote BN1 enters the circumferential contact portion of the transport roller 27 and the driven roller 28, and is further transported to the storage direction side by the transport roller 27. Then, the banknote BN1 that receives the frictional force on the main surface and the back surface by the transport belt 25 whose transport surface travels in the storage direction and the separation roller 26 that rotates counterclockwise is transported into the storage unit 20. At this time, the banknote BN1 pushes up the presser member 29 and is conveyed below the presser member 29 pushed up (FIG. 8).

  The banknote BN1 is pressed downward by the weight of the presser member 29 and placed on the uppermost layer of the banknote BNs. The banknote BN1 placed on the uppermost layer of the banknote BNs is further pressed from the pressing member 29 toward the stage 22 and stored in the storage unit 20 (FIG. 9).

  As described above, in a state where the transport belt 25 is pressed at the contact portion by the separation roller 26, the main surface of the banknote BN1 transported from the storage 16 is rubbed in the transport direction by the transport belt 25 to separate the back surface of the banknote BN1. The roller 26 rubbed in the storing direction. At this time, only the banknote BN1 is easily separated from the other banknotes BNs, and is transported through the contact portions of the transport belt 25 and the separation roller 26.

  As a specific example, the load torque at the time of separation of the banknote BN1 between the transport roller 250 of the storage 160 shown in FIG. 11 and the pulley 24 that rotates the transport belt 25 of the storage 16 was calculated. At this time, drive mechanisms of the same quality were connected to the conveying roller 250 and the pulley 24, respectively.

According to this result, it was 0.075 N · m for the conveying roller 250 and 0.023 N · m for the pulley 24. Thus, the load torque could be reduced by about 70%.
Therefore, since the load for rotating the pulleys 23 and 24 can be reduced, the load on the drive mechanism that rotates each roller can be reduced. Since the drive mechanism does not require a large output, the drive mechanism can be reduced in size, so that the bill processing apparatus 10 can be reduced in size and power consumption can be reduced. Further, the wear on the transport surface of the transport belt 25 can be reduced, and the life of the banknote processing apparatus 10 can be extended.
