ABSTRACT:
An indexing conveyor for receiving and conveying workpiece blanks comprising a base mounting a pair of horizontal chain conveyors having a series of conveying hands in laterally opposed pairs at predetermined spacing along the conveyor chains. A pair of vertical chain conveyors are positioned laterally outwardly of the horizontal conveyors and each carry a pair of workpiece-support fingers. The horizontal and vertical conveyors have chain-drive sprockets mounted on a common drive shaft and are synchronized such that workpiece blanks carried by the vertical conveyor fingers are deposited in horizontal conveyor hands as the vertical conveyor fingers travel downwardly past the horizontal conveyor. A stacker for workpiece blanks includes cam fingers carried by supports above an index position of the horizontal conveyor, and a ram for successively lifting workpieces from the horizontal conveyor against the fingers.
