ABSTRACT:
A palletizer for stacking articles. The apparatus comprises a vertically shiftable layer-arranging table, a vertically shiftable stacking platform and a transfer carriage horizontally shiftable between positions overlying the layer-arranging table and the stacking platform. The upper surfaces of the layer-arranging table and the transfer carriage are formed of a plurality of laterally-spaced members, these members defining therebetween table and carriage channels, respectively. Also disclosed is a horizontally shiftable rake having a plurality of laterally-spaced, downwardly projecting tines positioned to be received within the table and carriage channels. The layer-arranging table is initially adjusted to a lowered position for receiving articles thereon. The table is then raised to a position horizontally adjacent the transfer carriage and rake shifted downstream, raking the articles onto the carriage. The projection of the rake tines into the table channels, and subsequently into the carriage channels, ensures that the lowermost articles are transported in the raking operation. With the rake stationarily held at its position overlying the stacking platform, the layer-arranging table is lowered and the transfer carriage shifted from its position overlying the stacking platform to its position overlying the layer-arranging table, whereupon the sheets are wiped onto the stacking platform.
