Abstract
An arrangement for the automatic positioning of axial lead electronic components upon a walking beam includes a tray positioning mechanism and a tray removal mechanism. The tray positioning mechanism in positioned above the walking beam and includes a pair of facing end guides for receiving a plurality of component positioning trays in a stacked arrangement whereon are positioned a plurality of aligned electronic components. The tray positioning mechanism further includes a pair of vertically displaceable support rails for engaging each tray in turn and lowering it beneath the walking beam whereupon all of the components positioned on the tray are removed from the tray and are deposited upon the walking beam. The thus empty tray is then removed from a position adjacent to and straddling the walking beam by a roller assembly which sequentially displaces each emptied tray onto the tray removal mechanism. The tray removal mechanism receives each empty tray in turn and, using a combination of pneumatic valves and cylinders, arranges the trays in a vertically stacked array for re-use.
