DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball set in a pachinko island, in which pachinko balls and granular abrasives are pumped up while stirring, and the polished pachinko balls and abrasives are sorted out. The present invention relates to a pachinko ball lifting and polishing apparatus which is configured to recirculate and transfer pachinko balls to a supply gutter for a pachinko machine.

2. Description of the Related Art A conventional pachinko ball polishing apparatus is disclosed, for example, in Japanese Patent Application Laid-Open No. 59-222179. That is, the pumping polishing device is provided inside the pachinko island, and the upper end of the pumping pipe of the pumping polishing device projects upward from the upper part of the pachinko island, and is discharged from the upper end opening established at the upper end of the pumping pipe. A mixture of pachinko balls and a large amount of abrasive is sent out from the upper end port to a slug-shaped separating member extending obliquely downward. Thereby,
The abrasive material falls below the separating member and is separated from the pachinko balls, and the separated pachinko balls flow into the supply gutter and are conveyed to each pachinko machine. As described above, a large amount of the abrasive was separated from the polished pachinko ball only by the separating member.

[0003]

However, in such a conventional pachinko ball lifting and polishing apparatus, in order to completely separate a large amount of abrasive from the pachinko ball using only the separating member, the inclination angle of the separating member must be increased. Although it is necessary to increase the length of the separation member or the length of the separation member, it is not possible to sufficiently increase the inclination angle and the total length of the separation member due to the layout space above the island. There was a possibility that separation could not be performed sufficiently. As a result, there is a problem that if a small amount of abrasive material enters the supply gutter or the like, the conveyance of the pachinko ball may be hindered.

The present invention has been made in view of such a conventional problem. In order to efficiently transport the pachinko balls while reducing the installation space, the abrasive is completely separated from the pachinko balls. It is an object of the present invention to provide a pachinko ball lifting and polishing apparatus which can perform the polishing.
