Reference).

[Problems to be solved by the invention]

By the way, in the conventional cleaning device of the pachinko ball lifting and polishing apparatus, dirt attached to the surface of the polishing pellet is cleaned by removing it.
For this reason, the polishing pellets are consumed intensely and have to be replaced in a short period of time, which is very uneconomical. In addition, dirt that adheres to the surface of the polishing pellet is often greasy, such as hand grit, so that there is a problem that the shaved debris adheres to the surface again and complete cleaning cannot be expected. .

On the other hand, as described in JP-A-59-194774, a washing medium is mixed into a dirty abrasive pellet separated from pachinko balls and stored in a receiving tank, and the abrasive pellet and the washing medium are stirred. A pachinko machine that removes dirt from the polishing pellets while transferring the separated polishing pellets and the cleaning medium, and supplies the separated polishing pellets again to the circulation path of the pachinko balls. A pellet cleaning device in a ball polishing machine is known.

However, in this conventional apparatus, although it is possible to prevent the consumption of the abrasive pellets, a device for separating the cleaned abrasive pellets and the cleaning medium is required, so that the entire pellet cleaning apparatus becomes large and stirring is performed. In this case, the cleaning medium is liable to stick to the surface of the polishing pellet due to the generation of heat due to the transfer, and it is difficult to completely separate the polishing pellet and the cleaning medium.

Further, since the cleaning medium separated from the abrasive pellets is discharged to the outside as it is, there are many problems such as being wasteful and uneconomical.

The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a pachinko machine that can be used in a circulating manner while cleaning dirt on a polishing pellet with a cleaning liquid such as a liquid detergent. An object of the present invention is to provide a ball polishing apparatus.

[Means for solving the problem]

In order to achieve the above object, a pachinko ball pumping and polishing apparatus of the present invention has a pumping cylinder that inserts a spiral coil therein, introduces a pachinko ball and a polishing pellet, and lifts the pachinko ball while polishing the ball. A sorting device provided at an upper end opening of the lifting cylinder for sorting pachinko balls and polishing pellets; and a washing device for introducing and washing the polishing pellets selected by the sorting device.

The cleaning device is provided with a cleaning liquid storage tank containing a liquid detergent for washing off dirt adhering to the polishing pellet, and is fixedly provided by being immersed in the cleaning liquid in the cleaning liquid storage tank, and the polishing pellet is rotated by rotating a spiral inserted therein. And a drying device for drying the polishing pellets sent out of the cleaning liquid storage tank and returning the polishing pellets to the lifting cylinder.

[Operation] The polishing pellet separated from the pachinko balls by the sorting device and guided into the net-like transfer cylinder of the cleaning device is sent out of the cleaning liquid storage tank while being washed in the cleaning liquid in the cleaning liquid storage tank by the stirring and feeding action of the spiral. After being dried by the drying device, it is returned to the lifting cylinder again for circulating use.
