ABSTRACT:
A reciprocating linear drive for conveyors and like applications including a pair of cars mounted for translation on associated tracks. A reversible motor is coupled by a drive chain to the drive car for translating the drive car selectively in either direction through a defined drive stroke. An endless chain loop on the drive car is coupled by sprockets to revolve in one complete cycle during one stroke of the drive car. The conveyor car is coupled by a drag link to the chain loop to obtain uniform velocity of the conveyor car during an intermediate portion of the stroke and terminating in smooth cycloidal acceleration and deceleration at opposing ends of the drive stroke. In one embodiment, a pickup car is carried by the conveyor car and is selectively coupled by rack and pinion assemblies to the drive car for imparting continued motion of the drive car to the pickup car at ends of the stroke when the conveyor car is stationary.
