  In the state shown in FIG. 2, in the storage 16 in which the denomination banknote BNs corresponding to the command is stored by the carry-out command from the higher-order model, the stage 21 moves by driving the pressing means (not shown). The bills BNs placed on the transport belt 22 approach the transport surface of the transport belt 22. The stage 21 moves until the main surface of the banknote BN1 is pressed against the conveyance belt 22. Further, the stage 21 approaches the conveyance belt 22 side, and the pressing member 29 is retracted to the first conveyance guide 20b side. Thereafter, the presser member 29 remains retracted to the first transport guide 20b until the banknote BN1 is unloaded from the transport path 13 (FIG. 4).

  In the state shown in FIG. 4, the pulleys 23 and 24, the separation roller 25, and the drawing roller 27 are rotated in the clockwise direction (solid arrow direction) in FIG. 5. As the pulleys 23 and 24 are driven to rotate, the conveying surface of the conveying belt 22 travels in the unloading direction (solid arrow direction) in FIG. The driven roller 28 that is in circumferential contact with the drawing roller 27 rotates in the counterclockwise direction (broken arrow direction) in FIG. 5 following the clockwise rotation of the drawing roller 27.

  At this time, the uppermost banknote BN1 of the banknote BNs receives a frictional force from the transport surface of the transport belt 22 running in the carry-out direction in FIG. 5, 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 below the banknote BN2 are bundled together with the banknote BN1 and conveyed in the carry-out direction due to the frictional force generated between them. Then, the bundled banknotes BN are inserted into the separating portion where the conveyor belt 22 and the separating roller 25 overlap with the banknote BN1 at the head (FIG. 5).

  The main surface of the banknote BN1 inserted in the separation unit receives a frictional force in the carry-out direction from the conveyance surface of the conveyance belt 22. On the other hand, the back surface of the banknote BN1 receives a frictional force from the separating roller 25 rotating in the clockwise direction toward the storing direction.

  At this time, the frictional force from the conveying belt 22 to the main surface of the banknote BN1 is set to be larger than the frictional force from the separation roller 25 to the back surface of the banknote BN1. Further, the conveyance force in the carry-out direction of the banknote BN2 (= the pressure contact force against the conveyance surface of the conveyance belt 22 × the friction coefficient between the banknotes BN1 and 2) is the blocking force in the storage direction of the banknote BN2 (= the pressure contact with the separation roller 25). Force × friction coefficient between the banknote BN2 and the separation roller 25). In this case, only the banknote BN1 is separated from one banknote BN below the other banknote BN2, and is transported through the separating portion between the transport belt 22 and the separation roller 25 (FIG. 6).

  In this way, only one banknote BN1 separated from the banknote BNs is conveyed to the carry-out direction side. In addition, in order to make the frictional force from the conveyance belt 22 larger than the frictional force from the separation roller 25, besides applying an appropriate friction coefficient to the conveyance belt 22 and the separation roller 25, the rotational speed of the conveyance belt 22 is separated. It is realized by making it faster than the roller 25.

  Further, the banknote BN1 inserted into the separation portion of the conveyance belt 22 and the separation roller 25 is bent by the conveyance belt 22 and the separation roller 25 as shown in FIG. For this reason, the banknote BN1 is pressed from the main surface side to the back surface side by the conveyor belt 22, and is pressed from the back surface side to the main surface side by the separation roller 25, respectively, and a bending fold is attached to increase the strength of the banknote BN1. To do.

  Further, since the gap between the conveyance belt 22 and the separation roller 25 is wider than the gap between the conveyance roller 250 and the separation roller 260 shown in FIG. 14, the banknotes pressed from the conveyance belt 22 and the separation roller 25, respectively. The unevenness (rise angle) of BN1 is reduced. In particular, the load on the contact portion between the conveyance belt 22 and the separation roller 25 and the banknote BN1 can be reduced as compared with the case of FIG. For this reason, before and after the banknote BN1 is inserted into the separation portion between the transport belt 22 and the separation roller 25, even when the banknote BN1 is weak, folding and curling do not occur.

As a result, the banknote BN1 is prevented from being bent and the occurrence of a paper jam of the banknote BN1 that is stably carried out is suppressed.
In addition, when the number of banknotes BN inserted into the separation unit is large, the conveyor belt 22 bends, so that the load on the banknote BN1 can be suppressed, and the banknote BN1 can be stably separated and transported into one sheet. it can.

  In this way, the banknote BN1 that has been transported through the separating portion where the transport belt 22 and the separation roller 25 overlap and separated into one sheet is subjected to a frictional force by the transport surface of the transport belt 22 that travels in the carry-out direction, and a drawing roller. 27 and the driven roller 28 are transported to a circumferential contact portion (FIG. 7).

  In addition, since the banknote BN1 separated into one sheet is conveyed to the drawing roller 27 by the conveyance belt 22, the banknote BN1 generated between the conveyance roller 250 and the separation roller 260 seen in the storage 160 of FIG. Occurrence of a paper jam due to bending is prevented.

  When the banknote BN1 is inserted into the peripheral portion of the drawing roller 27 and the driven roller 28, the pulleys 23 and 24 stop rotating. Then, the banknote BN1 is taken out by being pulled out by receiving frictional force from the drawing roller 27 rotating in the clockwise direction and the driven roller 28 rotating in the counterclockwise direction following the banknote BN1 conveyed to the drawing roller 27. Is done. At this time, even if the banknote BN2 receives a frictional force in the carry-out direction from the banknote BN1, the banknote BN2 is suppressed from the conveyance belt 22 and receives a larger frictional force in the storing direction, so that it is prevented from being carried out together with the banknote BN1. The

Thus, the banknote BN1 carried out of 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.

8 and 9 are side views of the storage shown in FIG. 2 for explaining the storing operation of banknotes.
The banknote BN1 inserted from the deposit slot 11 or transferred from the other storage 16 after the command from the higher-level model is notified, is transported through the transport path 13 toward the storage 16.

  In addition, based on the command from the higher-level model, the stage 21 on which the banknote BNs is placed is retracted from the first transport guide 20b in the storage case 16 of the banknote BN1. By maintaining this state, a storage space for the stored banknote BN1 is secured in the storage unit 20 (FIG. 8). Further, by rotating the pulleys 23 and 24 and the drawing roller 27 counterclockwise in FIG. 8 (the direction of the broken line arrow), the conveyance surface of the conveyance belt 22 travels in the direction of the broken line arrow in FIG. The driven roller 28 that is in circumferential contact with the drawing roller 27 is rotated in the counterclockwise direction in FIG. 8 by the drawing roller 27 in FIG.

  In such a state, the banknote BN1 that has been transported through the transport path 13 is inserted between the drawing roller 27 and the driven roller 28. The main surface of the banknote BN1 is rubbed toward the storage direction side by the rotation of the drawing roller 27, and is conveyed to the separation unit where the conveyance belt 22 and the separation roller 25 overlap.

  The banknote BN1 inserted into the separation unit is rubbed in the storage direction on the main surface by the transport belt 22 and on the back surface by the separation roller 25, passes through the separation unit, and 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. 9). As described above, since the conveyor belt 22 and the separation roller 25 overlap each other, if the banknote BN1 passes through the separation section without causing paper jam, the banknote BN1 is bent. . The banknote BN1 with increased bending rigidity due to bending bends can be stably conveyed to the storage unit 20 and can reliably push up the presser member 29.

  The main surface of the banknote BN1 is pressed downward by the weight of the presser member 29 pushed up in this way, and is 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 21 and stored in the storage unit 20 (FIG. 2).

Below, the load with respect to the drive device in such a storage 16 and the storage 160 shown, for example in FIG. 13 is compared, and the result is demonstrated.
FIG. 10 is a graph of the load torque of the drive device in the embodiment, and FIG. 11 is an example of a graph of the load torque of the drive device.

  10 and 11, the horizontal axis represents the number of banknotes BN inserted into the separation unit, and the vertical axis represents the load torque (N · m) of the driving device according to the number. Yes. The load torque is obtained when a drive device of the same quality is connected to the pulley 23 (or pulley 24) of the storage unit 20 and the transport roller 250 of the storage unit 200, respectively. Moreover, the number attached | subjected to the element of each graph is overlap amount (mm). 10 and 11, “◇” indicates the load torque of the driving device of the banknote handling apparatus that is fed only by the rotation of the roller without overlapping, and the load torque is increased as the number of inserted sheets increases. Has increased. The “♦” mark is a development target and represents 50% of the load torque (“「 ”mark) of the driving device of the banknote handling apparatus that is fed only by the roller. In FIG. 11, the description of the load torque when the overlap amount is 0 mm is omitted.

  According to FIG. 10, the load torque increases as the number of sheets increases at each overlap amount. The amount of increase in the load torque due to the increase from 0 to 3 is about 0.04 N · m at the maximum (when the overlap amount is 1 mm), and about 0.02 N · m at the minimum (the overlap amount is 0.1 mm). 3 mm). Further, the amount of increase in load torque due to the increase in the number of inserted sheets from 1 to 3 is about 0.01 N · m to about 0.02 N · m in each overlap amount.

  Also in FIG. 11, the load torque increases as the number of sheets increases at each overlap amount. However, the amount of increase in the load torque due to the increase from 0 to 3 is about 0.05 N · m at maximum (when the overlap amount is 0.7 mm). Further, the amount of increase in load torque due to the increase in the number of inserted sheets from 1 to 3 is about 0.02 N · m to about 0.04 N · m in each overlap amount. It can be seen that the amount of increase in the load torque is increased compared to the case of FIG. In particular, in FIG. 11, it can be seen that the load torque when the number of inserted sheets is 2 or 3 is larger than that when the number of inserted sheets is 2 or 3 in FIG.

  Further, when the load torque of FIGS. 10 and 11 is compared with 50% of the load torque (“♦” mark) of the drive device of the banknote handling apparatus that is fed only by the rollers, the overlap amount is 0.5 mm and In the case of 0.3 mm, even if the number of inserted sheets is 1 to 3, it is less than 50%. On the other hand, in FIG. 11, when the number of inserted sheets is one, the overlap amount is less than 50%, but as the number of inserted sheets increases to two or three, it exceeds the 50%. The amount of lap appears.

  Therefore, the load torque of the driving device can be reduced by using the storage 16 of the present embodiment. In particular, the load torque can be reduced as the number of inserted sheets increases. As a result, the banknote handling apparatus 10 was able to be downsized by about 56% as compared with the banknote handling apparatus that is fed only by the rotation of a roller without overlapping.

  As described above, the storage 16 includes the conveyance belt 22 arranged in parallel and the separation roller 25 arranged so as to be nested in a non-contact manner in the conveyance belt 22 and overlapped with the separation unit. The banknotes transported by the transport belt 22 are inserted into the separation unit, and while being passed through the separation unit, are rubbed in the reverse direction at the time of carry-out from the separation roller 25 and separated into one sheet. Since the load on the driving device for driving the conveyor belt 22 at this time is reduced, a driving device with a small output can be used. As a result, the bill processing apparatus can be reduced in size and power consumption.
