The present invention relates to a coin storing and feeding device.

(Prior Art) In a conventional coin storing and feeding device, for example, the actual exploitation 64-4687
As described in Japanese Patent Publication No. 6, a storage space for storing coins is formed by a hopper, and a feeding belt made of a flat belt is arranged at the bottom of the storage space in a diagonally upward direction (feeding direction), and feeding is performed. The reverse rotation roller is arranged above the feeding belt in the direction. Then, by inserting coins into the storage space and rotating the payout belt in the payout direction, the coins on the payout belt are moved in the payout direction and the coins are returned to the storage space by the reversing rollers to return the coins in the one-layer state. Pay out.

Further, a foreign matter discharging shutter is provided at the bottom of the storage space on the side opposite to the feeding direction of the feeding belt, and when the foreign matter is discharged, the foreign matter discharging shutter is opened to discharge the foreign matter in the storage space downward. There is.

(Problems to be solved by the invention) However, in the conventional coin storing and feeding device, when a large amount of coins are thrown into the storing space at one time, the coins become dense on the feeding belt and the coins are fed into the feeding belt. There is a problem that coins cannot be delivered reliably because they are not followed. Further, when the coins are in a dense state on the feeding belt, the coins are likely to be jammed, and further, the weight of the coins in the storage space is all received by the feeding belt, and the feeding belt is seriously damaged.

Further, a foreign matter discharging shutter is provided at the bottom of the storage space on the side opposite to the feeding direction of the feeding belt, and it can be used for collecting coins in the storage space by opening the foreign matter discharging shutter, for example. Since the depth of the device becomes large and the foreign matter and collected coins are discharged downward by opening the foreign matter discharge shutter, a retractable collection box is provided below the storage space, and the foreign matter and collected coins are forwarded. Since a chute for guiding must be provided, the vertical dimension of the device becomes large, and there is a problem that the recovery work is troublesome.

The present invention has been made in view of such a point, and can reliably pay out coins along the payout belt, reduces the weight of the coins applied to the payout belt, and reduces damage to the payout belt. Further, it is an object of the present invention to provide a coin storage / feeding device which can suppress the depth dimension and the vertical dimension of the device and can easily perform a coin collecting operation.

(Means for Solving the Problem) According to the present invention, a main body in which a storage space for storing coins is formed and an inner bottom of the storage space of the main body are opposed to each other with a gap larger than the diameter of the coin to be processed. A pair of discs that are rotatably provided together with a holding space formed between them,
A support member that is disposed in the storage space and that restricts the amount of coins that enter the storage space from the storage space, and a protrusion that is used to hold coins and that has a width wider than the gap between the pair of discs are provided on the surface of the belt. The winding side portions that are provided at predetermined intervals in the vertical direction and that are wound around the lower outer peripheral positions of the pair of disks, and the rising side portions that extend from one of the winding side portions to the diagonally upper position.

Through 76, the passage switching plate 71 is switched to the position where the recovery passage 74 shown by the two-dot chain line in FIG. 1 is opened.

When the recovery switch 59 exposed by opening the side plate 51 is operated, the motor 25 of the drive mechanism 24 is rotated in the reverse direction so that the winding side portion 21 of the feeding belt 20 moves toward the coin recovery port 4. Then, the feeding belt 20 is rotated in the opposite direction (coin collecting direction), and the pair of disks 12 slidably contacting the feeding belt 20 rotate in synchronization with the clockwise direction in FIG.

Therefore, the coins in the storage space 2 are discharged all at once from the coin collection port 4 and are collectively collected in a short time. The coins in the hopper 61 of the coin replenishing unit 5 are collected at the same places as the coins collected from the coin collecting port 4 through the passage switching plate 71 and the collecting passage 74.

According to the present invention, the holding space is formed between the pair of disks at the inner bottom portion of the storage space, and the amount of coins entering the holding space from the storage space is regulated by the support member. Are not in a dense state, coins can be reliably delivered along the delivery belt, and a pair of disks forming the side walls of the storage space in a state where the coins are not dense in the storage space. Since the coins are rotated, the effect of stirring the coins by the pair of discs is large, the coins are less likely to be jammed, and the load on the feeding belts for the coins is reduced, and the damages of the feeding belts can be reduced. In addition, the side plate of the main body facing the winding side of the feeding belt is opened to open the coin collecting port, and the coin can be collected from the coin collecting port by driving the feeding belt.
