<P>PROBLEM TO BE SOLVED: To provide a Pachinko ball polishing and lifting apparatus stable in its lifting state to give little damage to a conveyor belt and hardly causing a ball bite in the case of using a sprocket. <P>SOLUTION: A Pachinko ball lifting portion 118 includes an anti-backing plate 67 located facing a driving pulley 7 and turning within a plane orthogonal to a rotating shaft 6 of the driving pulley 7, with a lower part as a fulcrum, and the sprocket 88 arranged above in proximity to the anti-backing plate and turning within a plane including the axis of a lifting duct 81 while part of recesses 87 lined up on the outer peripheral edge to fit Pachinko balls B is interposed into the lifting duct 81. The anti-backing plate 67 is urged to the driving pulley 7 side by a spring urge 79, and when the anti-backing plate approaches the driving pulley 7, its upper end is interposed into the lifting duct 81, and the Pachinko ball B is placed on the upper face. A one-way clutch 120 is built in the sprocket 88 to turn in the forward direction so that the Pachinko ball B is rolled upward only in a forward direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
