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 pachinko ball used in a pachinko game arcade. More specifically, the present invention relates to a pachinko ball polishing apparatus (hereinafter, abbreviated as “polishing apparatus”) configured to be able to know an appropriate replacement time of an abrasive used for polishing.

[0002]

2. Description of the Related Art As a conventional polishing apparatus, Japanese Patent Publication No.
An apparatus disclosed in Japanese Patent No. 6473 (hereinafter, referred to as a "first conventional apparatus") is known. A first conventional apparatus includes a polishing means for mixing and agitating while mixing abrasive grains into a pachinko ball having been played collected from an island in which a plurality of pachinko gaming machines are installed, and a polished surface polished by the polishing means. An abrasive grain separating means for separating the abrasive grains from the pachinko balls, and an abrasive grain falling means for flowing the abrasive grains separated by the abrasive material separating means to the polishing means for reuse are provided.
As described above, the abrasive grains used as the abrasive (member for polishing a pachinko ball) in the first conventional apparatus are poly,
It is also called a pellet or the like, and is generally formed of a synthetic resin such as nylon having a smaller diameter than a pachinko ball.

On the other hand, a polishing apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 4-9171 (hereinafter referred to as "second conventional apparatus") is also known. The second conventional apparatus is an apparatus using a polishing belt stretched along a conveyance path of a polished pachinko ball as an abrasive, and is a conveying apparatus for conveying a polished pachinko ball while sliding it on the polishing belt. It has a mechanism.
The polishing belt used in the second conventional apparatus is also called a polishing cloth, a polishing sheet, or the like, and is generally formed of a cloth, a nonwoven fabric, or the like.

The abrasive grains used in the first conventional apparatus are used for removing dirt from pachinko balls that have been played, ie, to which dirt has adhered. In addition, dirt adheres to the abrasive grains themselves, so that they cannot serve as abrasive grains. On the other hand, the polishing belt used in the second conventional apparatus also becomes dirty on its surface due to long-term use, and cannot serve as a polishing belt similarly to the above-mentioned abrasive grains. For this reason, in a pachinko game hall, in order to recover the polishing function, a task of periodically replacing dirty abrasive grains and a polishing belt, that is, an abrasive, with a new (cleaned) abrasive is performed.

[0005]

However, it is not always easy to know the appropriate replacement time of the abrasive, and the rule of thumb is irrespective of the operating rate of a pachinko game machine, that is, regardless of the frequency of use of the abrasive. Was based on the
Sometimes the exchanges were late and sometimes too early. Since the abrasive whose replacement has been delayed can no longer serve as an abrasive, even if it is polished using it, the surface of the pachinko ball cannot be removed, and hands and clothing etc. can be removed with the dirty pachinko ball. Could have contributed to complaints from players who polluted the game. On the other hand, if the replacement of the abrasive is too early, the abrasive that can still be used is discarded or washed, which is a cause of economic and labor waste. The technical problem to be solved by the invention described in each claim is to notify an appropriate replacement time of the abrasive used for polishing a pachinko ball, so that if replacement is necessary, this can be performed quickly and unnecessary. The purpose of this is to avoid economical and labor waste by refraining from the exchange.
