The storage unit 26 stores the washed abrasive pellets P discharged from the discharge port 37 of the washing drum tub 24, and an opening / closing shutter 45 is provided at the bottom of the storage unit 26. After the washing, the washing drum tub 24 is moved to a predetermined position, that is, a drain cock 38 by a limit switch 46 as a switch means.
Is set to stop in a state where is located on the lower side of the bottom.

Next, the operation of the first embodiment configured as described above will be described. When the second ball feed spring 6 is rotated by the drive of the second motor 7, the pachinko balls B and the polished pellets P in the lateral feed pipe 3 are transported into the lifting pipe 2 while being mixed by the second ball feed spring 6. Is done. The pachinko balls B and the polished pellets P transferred into the lifting pipe 2 continue to rise toward the upper end opening 9 while being further agitated and mixed by the first ball feed spring 4 rotated by the drive of the first motor 5. . When the pachinko ball B and the polishing pellet P are stirred and mixed by the first ball feed spring 4, dirt on the pachinko ball B adheres to or is removed from the polishing pellet P by contact friction with each other and is polished. In this manner, the pachinko balls B and the polished pellets P that have reached the upper part of the discharge pipe 2 are sent out from the opening 9 onto the cage 12 of the sorting device 8 and separated, and the pachinko balls B are supplied through a supply system (not shown). While being supplied to the pachinko machine, the dirty abrasive pellets P fall to the bottom of the box 8a from the gap between the cages 12. Then, the abrasive pellets P dropped to the bottom portion 28 are preferentially guided to the pellet storage portion 22 by the pellet introduction portion 29 and stored therein. When the pellet storage portion 22 is filled, the polished pellets P are returned to the lateral feed pipe 3 by the circulation pipe 14. Is done.

In order to wash the abrasive pellets P stored in the pellet storage 22, the open / close shutter 33 is used.
After the abrasive pellets P in the pellet storage section 22 are supplied into the washing drum tub 24 through the supply pipe 44, the opening / closing shutter 33 is closed. On the other hand, the water supply electromagnetic valve 40 is opened, and the warm water in the water storage tank 21 heated by the heater 27 is supplied into the washing drum tub 24 through the water supply pipe 39.
When a predetermined amount of water is supplied into the washing drum 24, the water supply electromagnetic valve 40 is closed to stop water supply. The water tank 21 is preliminarily provided with a detergent that generates little foam and does not require rinsing, for example, a special detergent that generates hydrogen and oxygen ions to activate water. At this time, by stirring the water in the water storage tank 21 by the stirring device 28, the ionic effect of the detergent is enhanced, and the washing action is significantly increased.

Next, the motor 35 is driven to rotate the washing drum tub 24, and the washing of the abrasive pellets P is started. When the washing drum tub 24 rotates, the abrasive pellets P are repeatedly transferred to the bottom and repeatedly dropped by the spiral transfer blades 36 on the inner peripheral surface of the washing drum tub 24, so that the pellets P are washed thoroughly and the dirt is completely removed.

In this way, when a certain period of time (about 30 minutes) elapses and the washing of the abrasive pellets is completed, the motor 35
Is stopped, and the washing drum tub 24 is stopped at a predetermined position set by the limit switch 46, that is, in a state where the drain cock 38 is located on the lower side. And drain cock 3
8, the washing water is collected in a container 47 such as a bucket, and when the washing water in the washing drum tub 24 is completely exhausted, the drain cock 38 is closed and the washing drum tub 24 is rotated again. At the same time, hot air is supplied from the hot air heater 25 to the air guide tube 43 and the supply
Through the washing drum 24. As a result, the abrasive pellets P after washing are quickly dried while repeating the transfer and dropping motions as in the washing (for example, about 2 hours at 25 degrees and about 1 hour at 35 degrees).

When the drying is completed in this manner, when the motor 35 is rotated in the reverse direction to reverse the rotation direction of the washing drum 24, the abrasive pellets P are transferred by the transfer blades 36 in the direction opposite to the direction at the time of washing. It is sent out from the polishing pellet discharge port 37 to the storage section 26 and stored therein.
5 is opened, and is returned into the horizontal feed pipe 3.

In the first embodiment described above, the water discharged from the dehumidifier 20 is always stored in the water storage tank 21 to secure it as washing water. It is not necessary to perform any large-scale construction, and the equipment cost can be significantly reduced.

In the first embodiment, the detergent is placed in the water storage tank 21. However, as another means, a detergent storage tank is provided, and when the abrasive pellets P are washed, the opening and closing shutter of the detergent storage tank is opened and closed. Alternatively, the detergent may be directly charged into the washing drum tub 24.
