<p><P>PROBLEM TO BE SOLVED: To provide a Pachinko ball grinding lifting/sending device that is stable in a lifting/sending state, suppressed in damage to a conveying belt, and hardly causes the bite-in of balls when using a sprocket. <P>SOLUTION: In a Pachinko ball lifting/sending part 118, there are arranged: an anti-back plate 67 which is positioned opposite to a drive pulley 7 and turns in a plane perpendicular to a turning shaft 6 of the drive pulley 7 with a lower part as a pivot; and the sprocket 88 which is arranged adjacent to the upper part of the anti-back plate, in which a portion of a recessed groove 87 formed at the external peripheral edge so that the Pachinko balls B may be fit therein is interposed in a lifting/sending conduit 81, and which turns in a plane including the center axial line of the lifting/sending conduit 81. When the anti-back plate 67 is biased to the side of the drive pulley 7 by a resilient means 79 and approaches the drive pulley 7, the upper end of the anti-back plate is interposed in the lifting/sending conduit 81 and the Pachinko balls are placed on the anti-back plate, and a one-way clutch 120 is assembled into the sprocket 88 so that the Pachinko balls B may turn to only the forward direction in which the Pachinko balls roll upward. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
