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