DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing apparatus for polishing a game ball used in a game machine, which is installed in a game machine island having a game machine.

[0002]

2. Description of the Related Art Conventionally, as a polishing apparatus for polishing a game ball represented by a pachinko ball, a lifting polishing apparatus which is configured to be used also as a lifting apparatus and which grinds a pachinko ball while lifting it is known. Have been.

[0003] This lifting and polishing apparatus is generally erected in the center of a gaming machine island, and is formed by rotatably inserting a screw member into a lifting pipe extending from a lower island to an upper island. The ball was polished by mixing a granular abrasive and a game ball molded with a synthetic resin into the pumping pipe and stirring and mixing the abrasive and the ball by rotating the screw member. .

[0004] Further, unlike the above-mentioned lifting polishing apparatus, a polishing apparatus which is not used as a lifting apparatus is also known. For example, Japanese Patent Publication No. 56-31218 and Japanese Patent Application Laid-Open No. 3-1930079 are disclosed.
There is a thing as shown in the gazette.

In the former publication, a ball is taken into a groove of a rotary drum, the ball is rotated by the rotation of the rotary drum, and a part of the peripheral surface of the rotary drum is covered with a polishing cloth. There is disclosed a technique in which a polishing cloth is rubbed against each other for polishing. The position where the sphere was taken in the rotating drum was located only on one side of the drum, and a sphere supply gutter was provided at this position.

[0006] On the other hand, in the latter publication, a ball is enclosed in an enclosed game machine, and is set in a circulation path of the ball. There is disclosed a technique in which a ball is pressed against a polishing member at the time of sending out to perform polishing.

[0007]

However, in the above-mentioned hoisting and polishing apparatus, since the apparatus is also used as the hoisting apparatus, the apparatus becomes considerably large, requiring a large installation space on the gaming machine island, and the assembling work is also required. There was also a problem that it became large and cost increased. In addition, there has been a problem that the replacement work becomes large if the replacement has to be performed due to a failure or a service life.

In addition, the ball and the granular abrasive must be separated from each other after polishing. In addition to a special separating mechanism for this purpose and a mechanism for distributing the polished ball, the separated abrasive is transported again. Many bulky mechanisms such as an abrasive recovery mechanism that circulates to the lower end of the pipe have been included. Therefore, these mechanisms have a large number of components and a complicated overall configuration, which has been a major obstacle in reducing costs.

[0009] The polishing apparatus described in each of the above publications can be installed compactly in a gaming machine island, and it is good if the game balls to be polished are sent to the polishing apparatus from one direction. When sent, the ball must be temporarily stored in one place before being introduced into the polishing apparatus, and then sent to the polishing apparatus. Therefore, there is a problem that a storage tank must be provided separately from the polishing apparatus, and the cost increases.

[0010] In particular, in the polishing apparatus described in the latter publication, there is no problem in the case where game balls are sent out one by one to the ball launching device, but in the case where it is interposed in a part of the ball circulation path in the game machine island. However, since the polishing processing speed is slow, there is a problem that the ball may be clogged in the middle of the course or the supply of the ball to the gaming machine may be insufficient. Further, there is a problem that a polishing apparatus must be provided for each gaming machine, and polishing apparatuses for the number of gaming machines are required, resulting in an increase in cost.

The present invention has been made in view of the above-mentioned problems of the prior art, and can smoothly and directly receive game balls sent from different directions and store temporary balls. No tank is required,
It is an object of the present invention to provide a polishing apparatus that can be formed in a compact configuration and that can reduce the cost and installation space of the apparatus itself.
