Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball polishing unit for cleaning a pachinko ball used in a pachinko machine.

[0002]

2. Description of the Related Art In the past, when cleaning a pachinko ball, a circulation path through which the pachinko balls discharged from a group of pachinko machines in a pachinko hall are collected and distributed again to each pachinko machine. A large amount of pachinko balls were collectively cleaned by a large ball polishing device installed inside.

[0003]

In the conventional method for cleaning a pachinko ball, the equipment is large and the equipment cost is high, and the pachinko machine has a high processing capacity in a pachinko hall where the number of pachinko machines is relatively small. There is a problem that it becomes excessive for the number of vehicles. An object of the present invention is to precisely clean a pachinko ball used in each pachinko machine for each pachinko machine.

[0004]

According to a first aspect of the present invention, a pachinko ball released from the pachinko machine to the outside of the pachinko machine or a pachinko ball released from the pachinko machine to the outside of the pachinko machine is provided. Is installed in the discharge flow path through which the ball passes, and a ball feed member that sequentially feeds the pachinko balls and a cleaning member that cleans the pachinko balls while rotating are installed in the ball guide case in which the ball guide passage is formed. The ball guiding passage has a configuration in which a pachinko ball passes through while contacting the cleaning member.

According to a second aspect of the present invention, a turn-back path through which the pachinko ball turns back in a U-turn shape and passes through the ball guiding path, a carry-in path through which the pachinko ball passes before entering the turn-back path, and the turn-back path. A carrying-out path through which a pachinko ball passing through the path passes is formed, and the cleaning member is provided with a first ball-polishing path formed in the middle of the carrying-in path and a second ball-forming path formed in the middle of the carrying-out path. It has a structure installed between the ball polishing passage and the ball polishing passage.

[0006]

According to the first aspect of the invention, the pachinko balls fed into the ball guiding passage in the ball guiding case installed in the pachinko ball supply passage or the discharge passage are sequentially fed by the ball feeding member to move through the ball polishing passage. When passing, the cleaning member makes contact with each pachinko ball while rotating, and each pachinko ball is cleaned by the cleaning member and then sent out from the ball guiding case.

According to the second aspect of the invention, when the pachinko ball passes through the first polishing path of the carry-in path and the second path of the carry-out path.
When the balls pass through the ball polishing passage, the cleaning members come into contact with the cleaning members and are doubled and cleaned in the ball guiding passage by the cleaning members.

[0008]

According to the invention of claim 1, the ball polishing unit is simply installed in the ball path through which the pachinko ball travels.
Each pachinko ball that travels along the ball path can be accurately cleaned while being fed to the other end, and the mechanism for feeding and cleaning the pachinko ball can be unitized and downsized to reduce the installation space. .

Further, since a ball polishing unit is installed in each pachinko machine and the pachinko balls used in each pachinko machine are cleaned in the middle of the ball path, the cleaning processing capacity is excessive or insufficient with respect to the number of pachinko machines. Problems can be resolved.

Furthermore, since the cleaning member rotates to come into contact with the pachinko balls to clean the pachinko balls, each pachinko ball can be cleaned evenly and effectively, and the contamination state of each part of the cleaning member is averaged. Therefore, it is possible to extend the usage period of the cleaning member and reduce the replacement frequency thereof.

According to the second aspect of the present invention, the pachinko balls that pass through the ball guide passage can be doubled and cleaned before and after the turn-back path, and each pachinko ball can be efficiently cleaned and cleaned. The effect can be enhanced.
