Description

  The present invention relates to a coin feeding device that feeds out coins stored in a storage unit from the storage unit, a coin processor equipped with the coin feeding device, and a coin feeding method.

  Conventionally, a coin depositing and dispensing machine configured to deposit and withdraw coins is known (see, for example, Patent Document 1). In such a coin depositing and dispensing machine, the coins inserted into the coin slot are stored in the respective storage units according to denomination. An opening is provided in the side surface of each storage unit, and a conveyor belt is disposed on the bottom surface of each storage unit. And the coin accommodated in each accommodating part is drawn | fed out from the opening of each accommodating part by the conveyance belt. In each storage unit, a reverse rotation roller is provided above the conveyance belt so as to close the opening of the storage unit, and the reverse rotation roller rotates in a direction opposite to the coin conveyance direction by the conveyance belt. ing. Here, the rotation speed of the reverse rotation roller is considerably faster than the speed of the conveyor belt, and specifically, for example, is twice to three times the speed of the conveyor belt. Further, a gap that allows passage of one coin is formed between the transport belt and the reverse rotation roller. By providing such a reverse rotation roller, coins stored in each storage unit are fed out one by one from the storage unit. The reverse rotation roller also has a function of stirring the coins stored in the storage unit.

  In such a coin depositing and dispensing machine, when two or more coins are caught between the conveyance belt and the reverse rotation roller, the conveyance belt and the reverse rotation roller are moved by moving the conveyance belt in the reverse direction. The coins caught between the two are released (for example, see Patent Document 2). However, in the conventional depositing / dispensing machine, when releasing the bite of the coin, the rotational driving force is not applied to the reverse rotation roller, or the coin rotates at the same speed as during the normal conveyance of the coin. Here, when releasing the bite of coins, if the rotational driving force is not applied to the reverse rotation roller, or if the reverse rotation roller is rotating at a considerably faster speed than the conveying belt, it is in the biting state. There was a problem that coins could not be efficiently released from the gap between the conveyor belt and the reverse roller.

As shown in FIG. 3, the size of the region between the pair of guide members 68 adjacent in the vertical direction is adapted to the size of the diameter of the denomination coin to be stored in each storage mechanism 60. , Have become different from each other.

  As shown in FIGS. 3 and 4, in each storage mechanism 60, a stopper solenoid 70 is provided on the downstream side of the reverse rotation roller 66 in the conveyance direction of the conveyance belt 64. As shown in FIG. 4, each stopper solenoid 70 has a plunger portion 70 a extending downward, and this plunger portion 70 a advances and retreats toward the conveyance belt 64. As shown in FIG. 4, when the plunger portion 70 a extends toward the conveyor belt 64, the coins on the conveyor belt 64 that have passed through the gap between the reverse rotation roller 66 and the conveyor belt 64 are stopped by the stopper solenoid 70. It is prevented from being sent to the transport mechanism 76. On the other hand, when the plunger portion 70a is retracted upward from the conveyance belt 64 from the position shown in FIG. 4, the coin stopped by the plunger portion 70a is sent to the conveyance mechanism 76.

  As shown in FIG. 4, in each storage mechanism 60, a coin detection unit 72 is provided on the downstream side of the reverse rotation roller 66 in the conveyance direction of the conveyance belt 64. The coin detector 72 is composed of a light emitting portion 72a and a light receiving portion 72b, and the light emitted from the light emitting portion 72a is received by the light receiving portion 72b. Further, as shown in FIG. 3, each storage mechanism 60 is provided with a sensor hole 72c through which light emitted from the light emitting portion 72a passes. When the coin passing through the gap between the reverse rotation roller 66 and the conveyor belt 64 is sent to the conveyor mechanism 76 by the conveyor belt 64, the light emitted from the light emitting portion 72a of the coin detector 72 is blocked by the coin. The coin detection unit 72 detects that a coin has been sent from the storage mechanism 60 to the transport mechanism 76.

  In each storage mechanism 60, it is configured to control whether or not coins are fed out from the storage mechanism 60 by exciting / releasing the stopper solenoid 70. In addition, the number of coins fed out from each storage mechanism 60 is counted by the coin detection unit 72. By performing these operations in the respective storage mechanisms 60, the necessary denominations of coins can be fed out from the respective storage mechanisms 60 by the required number.

  In the present embodiment, as described above, when a coin is fed out from each storage mechanism 60 and sent to the transport mechanism 76, the transport belt 64 circulates in the clockwise direction in FIG. 4 in the clockwise direction. As a result, the coins stored in the storage portions 62 of the storage mechanisms 60 are fed out from the storage portion 62 one by one by passing through the gap between the transport belt 64 and the reverse rotation roller 66.

  On the other hand, as shown in FIG. 9, when two or more coins are caught between the conveying belt 64 and the reverse rotation roller 66, the biting release process for releasing the bited coins is performed. Done. Specifically, while rotating the reverse rotation roller 66 in the clockwise direction in FIG. 4, the conveyor belt 64 is circulated and moved in the direction opposite to that when coins are paid out (that is, in the counterclockwise direction in FIG. 4). Thus, the coins caught between the transport belt 64 and the reverse rotation roller 66 are pushed back to the storage portion 62 and released. In the present embodiment, when such a coin biting release process is performed, the rotation speed of the reverse rotation roller 66 is set to be lower than the rotation speed during normal conveyance of the coins. More specifically, when a coin is fed out from each storage mechanism 60 and sent to the transport mechanism 76, the rotational speed of the reverse rotation roller 66 (peripheral speed: movement speed of the outer peripheral surface) is the speed of the transport belt 64 (the surface speed). The moving speed is considerably faster than the moving speed), and is specifically about three times the speed of the conveyor belt 64, for example. On the other hand, when the coin biting release process is performed, the rotational speed of the reverse rotation roller 66 is made substantially the same as the speed of the conveyor belt 64. When the rotation speed of the reverse rotation roller 66 is substantially the same as the speed of the conveyor belt 64, the bitten coins are pushed back to the storage unit 62 in the same posture, so that biting does not become serious. Further, by rotating the reverse rotation roller 66 at a lower speed than that during normal feeding, the torque applied to the reverse rotation roller 66 is increased, and the ability to release the biting is improved.

  The operations of the conveyor belt 64 and the reverse roller 66 as described above will be described in detail below. Specifically, a drive mechanism 80 that drives the conveyance belt 64 and the reverse rotation roller 66 in each storage mechanism 60 shown in FIG. 3 and the like will be described with reference to FIGS. Here, FIG. 5 is a top view of the drive mechanism 80 that drives the conveyor belt 64 and the reverse rotation roller 66, and FIGS. 6 to 8 are side views of the drive mechanism 80 shown in FIG.

  As shown in FIGS. 5 and 6, a plate 98 extending in the vertical direction is provided on the side of the conveyor belt 64 along the direction in which the conveyor belt 64 extends. A drive mechanism 80 for driving the transport belt 64 and the reverse rotation roller 66 is provided on the opposite side of the transport belt 64 and the like with respect to the plate 98.

  As shown in FIGS. 5 and 6, the drive mechanism 80 includes a drive pulley 81 and a timing belt 82 stretched around the drive pulley 81. The timing belt 82 is composed of an endless round belt. Further, as shown in FIGS. 5 and 6, on the opposite side of the plate 98 to the conveyor belt 64 and the like, the conveyor belt drive timing pulley 84, the reverse roller drive timing pulley 86, the pulley 88, the pulley 90, and the drive Force transmission pulleys 92 are provided, and the timing belt 82 is stretched around these pulleys. The drive pulley 81 is rotated in both forward and reverse directions by a drive motor (not shown). When the drive pulley 81 rotates, the timing belt 82 also circulates in synchronization. The rotation direction of the drive pulley 81 is controlled by the control unit 100 of the coin depositing and dispensing machine 10 described above. When the timing belt 82 circulates, the conveying belt driving timing pulley 84, the reverse roller driving timing pulley 86, and the like are also rotated.

  A shaft 84 a is connected to the transport belt drive timing pulley 84, and this shaft 84 a passes through the plate 98 and is connected to the transport belt drive pulley 65. For this reason, when the conveying belt driving timing pulley 84 rotates, the conveying belt driving pulley 65 also rotates in synchronization with the shaft 84a.

  A shaft 86 a is connected to the reverse roller driving timing pulley 86, and this shaft 86 a passes through the plate 98 and is connected to the reverse roller 66. Therefore, when the reverse roller driving timing pulley 86 rotates, the reverse roller 66 also rotates in synchronization with the shaft 86a. Further, a one-way clutch (not shown) is provided between the reverse roller driving timing pulley 86 and the shaft 86a, and when the reverse roller driving timing pulley 86 rotates in the clockwise direction in FIG. The rotational driving force by the reverse roller driving timing pulley 86 is transmitted to the shaft 86a through the one-way clutch. When the reverse roller driving timing pulley 86 rotates in the counterclockwise direction in FIG. The connection between the driving timing pulley 86 and the shaft 86a is cut off, so that the rotational driving force by the reverse rotation roller driving timing pulley 86 is not transmitted to the shaft 86a. In this case, the reverse rotation roller with respect to the shaft 86a. The driving timing pulley 86 is freely rotated.

  As shown in FIGS. 5 and 6, a reverse roller driving gear 87 is connected to the shaft 86 a. A shaft 92a is connected to the driving force transmission pulley 92, and a driving force transmission gear 94 is connected to the shaft 92a. The reverse roller driving gear 87 and the driving force transmission gear 94 mesh with each other. When the driving force transmission gear 94 rotates, the rotational driving force is transmitted from the driving force transmission gear 94 to the reverse roller driving gear 87. It is to be transmitted. Further, a one-way clutch (not shown) is also provided between the reverse roller driving gear 87 and the shaft 86a. When the reverse roller driving gear 87 rotates in the clockwise direction in FIG. The rotational driving force by the driving gear 87 is transmitted to the shaft 86a via the one-way clutch. When the reverse roller driving gear 87 rotates in the counterclockwise direction in FIG. 6, the one-way clutch causes the reverse roller driving gear 87 to rotate. Is disconnected from the shaft 86a, so that the rotational driving force by the reverse rotation roller driving gear 87 is not transmitted to the shaft 86a. In this case, the reverse rotation roller driving gear 87 is free with respect to the shaft 86a. To rotate.

  Further, in the present embodiment, the diameter of the driving force transmission gear 94 is, for example, about three times the diameter of the reverse rotation roller driving gear 87. The diameter of the conveyance belt driving timing pulley 84 is substantially the same as the diameter of the reverse roller driving timing pulley 86.

  Next, in the drive mechanism 80 shown in FIGS. 5 and 6, the operation when the coins are fed out from the storage mechanisms 60 and sent to the transport mechanism 76 will be described with reference to FIG. 7. When the coins are fed out from each storage mechanism 60 and sent to the transport mechanism 76, the drive pulley 81 is controlled by the control unit 100 of the coin depositing and dispensing machine 10 and the drive pulley 81 rotates clockwise in FIG. The belt 82 also circulates in the clockwise direction in FIG. As a result, the conveying belt driving timing pulley 84 rotates in the clockwise direction in FIG. Therefore, the rotational driving force of the conveying belt driving timing pulley 84 is transmitted to the conveying belt 64 through the shaft 84a, and the conveying belt 64 circulates in the clockwise direction in FIG. On the other hand, the reverse roller driving timing pulley 86 and the driving force transmission pulley 92 rotate in the counterclockwise direction in FIG. As a result, the driving force transmission gear 94 rotates in the counterclockwise direction in FIG. 7, and the reverse rotation roller driving gear 87 engaged with the driving force transmission gear 94 rotates in the clockwise direction in FIG.

  Here, a one-way clutch is provided between the reverse roller driving timing pulley 86 and the shaft 86a. For this reason, when the reverse roller driving timing pulley 86 rotates counterclockwise in FIG. 7, the connection between the reverse roller driving timing pulley 86 and the shaft 86a is cut off by the one-way clutch, and the reverse roller driving timing. The rotational driving force by the pulley 86 is not transmitted to the shaft 86a. On the other hand, a one-way clutch is also provided between the reverse roller driving gear 87 and the shaft 86a. However, when the reverse roller driving gear 87 rotates in the clockwise direction in FIG. The rotational driving force by the gear 87 is transmitted to the shaft 86a via the one-way clutch. For this reason, the shaft 86a also rotates in the clockwise direction, and the reverse rotation roller 66 connected to the shaft 86a rotates in the clockwise direction in FIG.

  In the present embodiment, as described above, the diameter of the driving force transmission gear 94 is, for example, about three times the diameter of the reverse rotation roller driving gear 87. For this reason, the rotational speed of the reverse roller driving gear 87 is approximately three times the rotational speed of the driving force transmission gear 94. As a result, the rotational speed of the shaft 86a connected to the reverse rotation roller driving gear 87 is approximately three times the rotational speed of the shaft 84a connected to the conveying belt driving timing pulley 84. In this way, when the coins are fed out from each storage mechanism 60 and sent to the transport mechanism 76, the rotational speed of the reverse rotation roller 66 is about three times the speed of the transport belt 64. Specifically, when the coins are fed out from each storage mechanism 60 and sent to the transport mechanism 76, the rotation speed (circumferential speed) of the reverse rotation roller 66 is 415 mm / s, and the speed (circumferential speed) of the transport belt 64 is 140 mm / second. s.

  Next, in the drive mechanism 80 shown in FIGS. 5 and 6, two or more coins are caught between the conveying belt 64 and the reverse rotation roller 66 as shown in FIG. 9, and the caught coins are released. The operation at the time of performing the biting release process for this will be described with reference to FIG. When the coin biting release process is performed, the driving pulley 81 is controlled by the control unit 100 of the coin depositing and dispensing machine 10 so that the driving pulley 81 rotates counterclockwise in FIG. 8, and the timing belt 82 is also synchronized. Then, it circulates in the counterclockwise direction in FIG. As a result, the conveyor belt driving timing pulley 84 rotates counterclockwise in FIG. For this reason, the rotational driving force of the conveying belt driving timing pulley 84 is transmitted to the conveying belt 64 via the shaft 84a, and the conveying belt 64 circulates in the counterclockwise direction in FIG. On the other hand, the reverse roller driving timing pulley 86 and the driving force transmission pulley 92 rotate in the clockwise direction in FIG. As a result, the driving force transmission gear 94 rotates in the clockwise direction in FIG. 8, and the reverse rotation roller driving gear 87 engaged with the driving force transmission gear 94 rotates in the counterclockwise direction in FIG.

  Here, a one-way clutch is provided between the reverse roller driving timing pulley 86 and the shaft 86a. However, when the reverse roller driving timing pulley 86 rotates in the clockwise direction in FIG. The rotational driving force by the reverse roller driving timing pulley 86 is transmitted to the shaft 86a through the one-way clutch. On the other hand, a one-way clutch is also provided between the reverse roller driving gear 87 and the shaft 86a. When the reverse roller driving gear 87 rotates counterclockwise in FIG. 8, the one-way clutch drives the reverse roller. The connection between the gear 87 and the shaft 86a is cut off, and the rotational driving force by the reverse rotation roller driving gear 87 is not transmitted to the shaft 86a. In this way, since only the rotational driving force by the reverse pulley driving timing pulley 86 is transmitted to the shaft 86a via the one-way clutch, the shaft 86a also rotates in the clockwise direction. The reverse rotation roller 66 connected to 86a rotates in the clockwise direction in FIG.

  As described above, the diameter of the conveyance belt driving timing pulley 84 is substantially the same as the diameter of the reverse rotation roller driving timing pulley 86, so that the timing belt 82 rotates counterclockwise in FIG. In the case of the circular movement in the direction, the rotational speed of the reverse roller driving timing pulley 86 is substantially the same as the rotational speed of the driving timing pulley 84. Therefore, the rotational speed of the shaft 86 a connected to the reverse roller driving timing pulley 86 is substantially the same as the rotational speed of the shaft 84 a connected to the conveying belt driving timing pulley 84. In this way, when the coin biting release process is performed, the rotational speed of the reverse rotation roller 66 is approximately the same as the speed of the transport belt 64. Specifically, when the coin biting release process is performed, the rotation speed (circumferential speed) of the reverse rotation roller 66 is 145 mm / s, and the speed (circumferential speed) of the conveyor belt 64 is 140 mm / s. For reference, the rotation direction and speed of the conveyor belt 64 and the reverse rotation roller 66 during normal feeding and biting release processing are shown in FIG.

  As described above, when the conveying belt 64 moves in the coin feeding direction by the driving mechanism 80 as shown in FIGS. 5 to 8, the rotational speed of the reverse rotation roller 66 is about three times the speed of the conveying belt 64. On the other hand, when the conveyance belt 64 moves in the direction opposite to the coin feeding direction, the speed of the conveyance belt 64 does not change, but the rotation speed of the reverse rotation roller 66 decreases, and the rotation speed of the reverse rotation roller 66 changes. The speed is approximately the same as 64 speeds. In the present embodiment, the driving pulley 81 constitutes a conveying belt driving unit that drives the conveying belt 64, the timing belt 82, the conveying belt driving timing pulley 84, the reverse roller driving timing pulley 86, and the driving force transmission. By combining the pulley 92, the reverse roller driving gear 87, the driving force transmission gear 94, and the like, a driving force transmission mechanism that transmits the driving force by the conveying belt driving unit to the conveying belt 64 is configured. As described above, the reverse rotation roller 66 is also connected to such a driving force transmission mechanism, and the driving force by the conveyor belt drive unit is transmitted to the reverse rotation roller 66 via the driving force transmission mechanism.

  Further, in the present embodiment, the coin feeding device is configured by the storage unit 62, the conveyance belt 64, the reverse rotation roller 66, the conveyance belt drive unit, and the driving force transmission mechanism.

  In the drive mechanism 80 configured as described above, the speed of the conveyor belt 64 and the rotational speed of the reverse rotation roller 66 are substantially the same when the coin biting release process is performed. However, the present invention is not limited to such an embodiment. The ratio of the rotational speed of the reverse rotation roller 66 to the speed of the conveyor belt 64 is 0.5 to 1 when the coin biting release process is performed by changing the arrangement and size of each component in the drive mechanism 80. .5, preferably in the range of 0.8 to 1.2.

  As described above, in the coin feeding device of the present embodiment, when the biting release process for releasing the coin bitten between the conveyance belt 64 and the reverse rotation roller 66 is performed, the conveyance belt 64 is moved to the coin. The reversing roller 66 is moved in the direction opposite to the feeding direction, and the rotation speed of the reverse rotation roller 66 is smaller than the rotation speed during normal conveyance of coins. As a result, when the reverse rotation roller 66 rotates at a considerably higher speed than the conveyor belt 64 when the coin biting release process is performed, the reverse rotation is reduced by reducing the rotation speed of the reverse rotation roller 66. The speed difference between the rotation speed of the roller 66 and the speed of the conveyor belt 64 can be reduced. In this case, since the bitten coins are pushed back to the storage unit 62 in the same posture, the biting does not become serious. Further, by rotating the reverse rotation roller 66 at a lower speed than that during normal feeding, the torque applied to the reverse rotation roller 66 is increased, and the ability to release the biting is improved.

  In the coin feeding device of the present embodiment, the driving force transmission mechanism (timing belt 82, conveyance belt driving timing pulley 84, reverse roller driving timing pulley 86, driving force transmission pulley 92, reverse roller driving gear 87, The driving force transmission gear 94 and the like are concretely set so that the rotation speed of the reverse rotation roller 66 is smaller than the rotation speed during normal conveyance of coins when the conveyance belt 64 moves in the direction opposite to the coin feeding direction. In order to reduce the rotational speed of the reverse rotation roller 66 from about three times the speed of the transport belt 64 to approximately the same speed as the speed of the transport belt 64, driving by the transport belt drive unit (drive pulley 81) is performed. The force is transmitted to the conveyor belt 64 and the reverse rotation roller 66, respectively.

  In the coin feeding device of the present embodiment, the ratio of the rotational speed of the reverse rotation roller 66 to the speed of the transport belt 64 is within the range of 0.5 to 1.5 when the coin biting release process is performed. Preferably, the ratio is more preferably in the range of 0.8 to 1.2, and the speed of the conveyance belt 64 and the rotation speed of the reverse rotation roller 66 are substantially the same. More preferably. When the speed difference between the rotation speed of the reverse rotation roller 66 and the conveyance belt 64 is reduced so as to meet the above conditions, the bitten coins are pushed back to the storage unit 62 in the same posture. The crowd does not get worse. Further, by rotating the reverse rotation roller 66 at a lower speed than that during normal feeding, the torque applied to the reverse rotation roller 66 is increased, and the ability to release the biting is improved.

  Further, in the coin depositing and dispensing machine (coin processing machine) 10 of the present embodiment, the conveying belt 64 and the reverse rotation roller 66 of the coin feeding device are controlled by the control unit 100. When the coin biting release process is performed, the control unit 100 controls the drive pulley 81 so that the rotation direction of the drive pulley 81 is counterclockwise as shown in FIG. The belt 64 moves in the direction opposite to the coin feeding direction, and the rotation speed of the reverse rotation roller 66 becomes smaller than the rotation speed during normal conveyance of coins.

  In addition, the coin feeding device according to the present embodiment and the coin depositing and dispensing machine 10 including the coin feeding device are not limited to the above-described modes, and various changes can be made.

  For example, in the coin depositing and dispensing machine 10, the above-described feeding mechanism 30 for feeding coins inserted into the coin insertion slot 16 one by one is provided instead of providing the above-described coin feeding device in the storage mechanism 60 for storing coins. You may provide a coin feeding device like this. A foreign substance such as a clip may be mixed into the receiving portion 32 of the feeding mechanism 30 via the coin insertion slot 16, and such a clip or the like may be caught between the transport belt 34 and the reverse rotation roller 36. However, when the coin feeding device according to the present embodiment is provided in the feeding mechanism 30, the foreign matter in the biting state is returned to the receiving portion 32 and is taken out of the machine body via the coin insertion port 16. It comes to be. It should be noted that a mechanism for sending coins and foreign matter in the coin insertion slot 16 to the reject box may be provided, and foreign matters such as such clips may be sent to the reject box.

  As another modified example, when the coin biting release process is performed, not only the rotation speed of the reverse rotation roller 66 is decreased, but also the speed of the transport belt 64 is decreased as compared with the normal transport of coins. May be. By reducing the speed of the conveyor belt 64, when the conveyor belt 64 moves in the direction opposite to the coin feeding direction, it is possible to increase the torque applied to the coins in the bitten state. It is possible to more efficiently release coins caught between 64 and the reverse rotation roller 66.

  Further, in the coin feeding device of the present invention, as shown in FIG. 5 to FIG. 8, as a mechanism for making the rotational speed of the reverse rotation roller 66 smaller than the rotational speed at the time of normal transport of coins when performing the biting release processing. The drive mechanism 80 is not limited to this. When carrying out the biting release process, if the conveyor belt 64 moves in the direction opposite to the coin feeding direction and the rotation speed of the reverse rotation roller 66 is smaller than the rotation speed during normal conveyance of the coins, Various other configurations of mechanisms can be used.
