Abstract
The present invention relates to a bi-directional transfer mechanism which is driven by the drive shaft of a conveyor system. The transfer mechanism includes a pair of vertically displaceable lift tables with a conveying member reeved thereon such that the conveying member is driven in one direction on the first lift table and in a different direction on the second lift table. By selectively displacing the first and second lift tables between an engaging position whereby the conveying member is displaced above the conveying surface of the conveyor system and a non-engaging position whereby the conveying member is displaced below the conveying surface of the conveyor system, the transfer mechanism can transfer articles in two directions.
