Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin processing device installed in a coin game machine island, which is formed by arranging a plurality of coin game machines using coins as a play medium.

[0002]

2. Description of the Related Art Conventionally, a coin processing device for washing coins, which is a play medium, has been installed outside a coin game machine island. Therefore, the coins overflowing from the slot machine in the coin game machine island or the supply conveyor on the upper part of the island are first sent to the recovery conveyor (underground) below the island, and then the recovery conveyor causes the coins to be located outside the island. It was transported to and washed and stored in a tank. The coins in the tank were supplied to the replenishing conveyors on the upper part of each island as needed so that the coins were returned to the island again.

Further, a coin processing device installed in a polishing chamber outside the island lifts the inside of the pipe while stirring the coin and the granular polishing material, and the coin and the polishing material polished at the upper end of the pipe. The coin is separated from the abrasive while the abrasive is circulated and the abrasive is circulated. The abrasive material is a granular material made of synthetic resin, and when this abrasive material is agitated with the coin, it comes into contact with the coin and adsorbs dirt. The abrasive is
It is circulated in the polishing apparatus and used repeatedly.

[0004]

However, in such a conventional coin processing device, a polishing chamber for separately installing it, a tank for storing coins, and a coin in the polishing chamber are provided. There is a problem in that equipment such as a large-scale conveyor that conveys to a supply conveyor on the upper part of the island is required, the installation space is increased, the equipment cost is high, and the management cost is high.

Further, since the surface of the coin has many irregularities, no matter how much the granular abrasive having a certain size is used, it is impossible to clean the irregularities of the coin and stains on the concave portions. There was a problem. In this case, using a fine powdery abrasive, depending on the method of polishing,
It is possible to grind even the details of concaves and convexes of coins and concaves, but this is not possible because there is a problem with the processing of the powdery abrasive after polishing.

Further, since the dirt is adsorbed to the abrasive material by polishing the coin, it is necessary to wash the abrasive material on a regular basis, which requires a lot of work and is not easy to use. In this case, it is conceivable to wash with a jet water stream without using an abrasive to be reused, but the treatment of water after washing becomes a problem, and for example, in the method of sending normal hot air to evaporate the water, strong water is removed. Electricity and evaporated water adversely affect the inside and surroundings of the device, and dissolved matter such as dirt contained in the water remains on the coin, and the coin does not appear glossy or remains as a group. Such obstacles may occur.

The present invention has been made by paying attention to such a conventional problem, and it is installed in an island, and a coin, which is a play medium, can be washed in the island, thereby saving space.
