BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin delivery device applied to a coin processing machine such as a coin counting machine, a coin sorting machine and a coin wrapping machine.

[0002]

2. Description of the Related Art Conventionally, a coin dispensing apparatus stores a large amount of coins in a coin storage unit, and drives a conveyor of the coin storage unit for a predetermined time to feed coins by a predetermined amount to a rotating disk, and to feed the coin to a rotating disk. The centrifugal force sends the coin to the coin path around the periphery of the disk, and the coin path performs predetermined coin processing such as counting, sorting, and sorting coins (coin counting machines, coin sorting machines, etc., depending on the purpose). I have.

[0003] The meaning of storing coins in the coin storage section and feeding coins by the rotating disk while replenishing the coins by a predetermined amount to the rotating disk is as follows.
In order to put a large amount of coins on a rotating disk and send it out by centrifugal force due to rotation, the output of the drive motor that rotates the rotating disk must be large. This is because the radius of the rotating disk must be sufficiently large in order to make a large number of coins horizontal and to defeat coins that have been raised.

[0004]

By the way, recently, the diameter of the rotating disk has been reduced to a small diameter (for example, 100 mm diameter), the drive motor has been reduced in size, and the amount of coins directly accommodated in the rotating disk has been increased (for example, 200 sheets). There is also a demand for high-speed processing at a processing speed of about 10 sheets per second (high-speed processing based on the diameter of a rotating disk having a small diameter).

Conventionally, the rotating disk has a diameter of about 250 mm and the processing speed is about 30 sheets per second. However, in order to meet the above-mentioned demand, the load of a large number of coins is increased only by reducing the size of the rotating disk. Because of the disk, it is not possible to meet the demand for a large amount of coins to be stored directly on the rotating disk, and it is necessary to pursue a fundamental structure. In particular, even with a rotating disk having a small diameter, it is necessary to devise a method of preventing a large amount of coins from being applied to the rotating disk and a method of reliably falling down coins.

[0006] The present invention has been made in view of such a point, and reduces the load on the rotating disk even when a large number of coins are inserted into the rotating disk, and ensures that even if coins stand on the rotating disk. Tilt in, perform a reliable coin dispensing, and to provide an effective coin dispensing apparatus particularly downsizing and miniaturization of the drive motor of the rotating disc.
