Apparatus for handling cartridge shell plates of photographic film cartridges

摘要

A cartridge shell plate stacking apparatus (2) comprises a plurality of arms (7) circulating along an annular cam rail (17). Each arm (7) has a magnet (15) in its distal end (7a). The cam rail (17) lowers the distal end (7a) of the arm (7) in a pick-up station (5a-5d) to cause the magnet (15) to attract one of cartridge shell plates (4) successively conveyed on a bucket conveyer (8) and hold the shell plate (4) in the horizontal state with plush ribbons (9a,9b) stuck on the upside surfaces. The cam rail (17) also lowers the distal end (7a) of the arm (7) in a piling station (5a-5d) wherein a piling box (5a-5d) having a cut-out (27,54) formed in the top edge of a side wall (25,52b) is disposed. Although the distal end (7a) passes through the cut-out (27,54), the cartridge shell plate (4) cannot pass and strikes against the side wall (25,52b), thereby to drop into the piling box (5a-5d).
