The inside of the box body 7 is divided by a partition wall 3 at the communication point between the transverse feed vibro and the cylindrical body 11, and cavities 14 and 15 are formed in the upper and lower parts of the cylindrical body 11. The dust storage drawer 16 is removably inserted therein. Further, a dust collection port 17 is formed on the top surface of the box body 7 in communication with the upper cavity 15, and a suction pipe 19 of a dust advancer 18 is connected to the dust collection port 17.

A sorting device 21 is installed at the upper end outlet 20 of the lifting pipe 2 . The sorting device 21 has a container 22 with a gap smaller than the diameter of the pachinko balls in order to separate the pachinko balls and the polishing pellets P that are being conveyed, and a tray 23 that collects the polishing pellets 1-P that have fallen from the container 22. provided and configured.

A circulation pipe 25 is connected to the bottom of the tray 23 and communicates with the polishing pellet supply section 24 of the cross-feeding vibro.
Further, a branch pipe 27 that communicates with the polishing pellet intake port 26 of the cleaning section 8 is connected in the middle of the circulation pipe 25 . Reference numeral 28 denotes an opening/closing shutter provided in the polishing pellet supply section 24.

Reference numeral 29 denotes an opening/closing shutter provided at the polishing pellet intake port 26.

The pachinko ball lifting and polishing device has the above configuration.

Normally, the opening/closing shutter 28 of the polishing pellet supply section 24 is open, and the opening/closing shutter 29 of the polishing pellet intake port 26 is normally closed. Further, the pachinko balls discharged from each pachinko machine are introduced into the transverse feed vibro from the supply port 30 via the gutter member, and the polishing pellets I-P are supplied and filled into the transverse feed vibro from the supply section 24.

When the rotating member 1O is rotated by the drive of the motor 9, the pachinko balls and the polishing pellets P are mixed by the spiral coil 10c and transferred into the lifting pipe 2. The pachinko balls and polishing pellets P transferred into the lifting pipe 2 are further stirred and mixed by the helical coil 3 which is rotated by the drive of another motor 4, gradually increasing the amount thereof and rising toward the upper end outlet 20. continue. When the pachinko balls and polishing pellets P are stirred and mixed by the spiral coil 3, dirt from the pachinko balls is attached to or removed from the polishing pellets P due to mutual contact friction and is polished. The pachinko balls and polishing pellets P that have reached the upper part of the lifting pipe 2 are transported to the upper end outlet 20
The abrasive pellets P are sent out onto the holder 22 of the sorting device 21 and separated, and the abrasive pellets P fall from the gap between the holder 22 into the saucer 23 and are fed into the circulation pipe 25 by the polishing pellet supply section 24.
