PINBALL POLISHING DEVICE

PURPOSE:To install a polishing device without widening the width of the insular base of pinball machines by obtaining composition for the title device in which two screw feeder units are provided so that the units can have acclivities respectively and can be made into an X-shape, pinballs are carried together with abrasives in the sequence of a first unit and a second unit, and the pinballs are separated from the abrasives between the guiding out port of the latter unit and the guiding in port of the former unit. CONSTITUTION:Out pinballs 21 elected from respective pinball machines 2 of an insular base 1 of the pinball machines are collected in an insular base lower part space 4 and guided from a conduit 22 to a first unit 11. The pinballs 21 are carried upward together with abrasives 23 and polished by a screw feeder 17, guided through a passage 13 to a second unit 12, and polished again in the second unit 2. The pinballs 21 and the abrasives 23 are dropped from a guiding out port 16b onto a duckboard 14a of a separating device 14, the abrasives 23 are guided to a guiding in port 15a of the first unit 11, and the pinballs 21 are rolled on the duckboard 14a, ejected to the exter nal part of the separating device 14, and distributed into the respective pinball machines 2. Thus, the pinballs can be polished without widening the width of the insular base of the pinball machines by using the above-mentioned composition for the title device.
