PURPOSE:To realize a whole change of a pellet which is dirted during polishing operation of a pachinko polisher. CONSTITUTION:Mixed pachinko balls (used for Japanese pinball game) and pellets are both taken out compulsively from an outlet at an upper part of a polisher by a vane 4 which rises up so that it is inserted between an exterior cylinder and the screw cylinder 4 when a screw cylinder 4 revolves. The pellets which are now dirted are all fed to a pellet washer, and the pellets cleanly washed are supplied to the polisher. By this method, without stopping the polisher, the pellets can be taken out wholly and replaced automatically by the cleanly washed pellets. |
