A system for transferring workpieces generally vertically from a station at one height in a workpiece support or transfer device to a station at another height in another transfer device or support. The workpiece is moved vertically by an elevator which travels along a path through the stations from a point below the lower station to a point above the upper station. To smoothly and rapidly move the workpiece the elevator is accelerated and decelerated and dwells at least when picking up and depositing a workpiece. To avoid collisions, interference and the necessity of precisely synchronizing movement of the transfer and elevator, when in its fully raised and lowered positions, the elevator is clear of and does not interfere with the transfer and supports and any workpieces in the stations.

Workpiece transfer system

A multiple station conveyor having a lift and carry shuttle to advance workpieces. To permit a normal work height for the workpieces when in the stations while providing a relatively long vertical stroke for the shuttle it is raised and lowered by Scott Russell lift mechanisms disposed beside and laterally outside of the shuttle.

Workpiece transfer

A mechanical press has an elevated welding station and a workpiece conveyor extending through the press at a level spaced below the welding station. A lift mechanism below the conveyor is designed to elevate the platen with a straight line vertical motion in two successive steps to first engage a workpiece on the conveyor and then elevate the workpiece to the welding station. Thereafter the lift mechanism lowers the platen with a straight line vertical motion in two successive steps to first deposit the welded workpiece on the conveyor and then recede to its starting position. The drive for the lift mechanism gradually accelerates the platen at the beginning of each step and gradually decelerates it to a near zero velocity at the end of each step.

Mechanical welding press

A mechanism for loading workpieces into and/or unloading workpieces from a stamping press has a workpiece carrying arm and includes a drive mechanism for reciprocating the arm horizontally through a desired stroke and for reciprocating the arm vertically adjacent the opposite ends of its stroke. The drive mechanism comprises a crank for shifting the arm horizontally and a second crank for shifting the arm vertically. The cranks are operated sequentially and in timed relation by a pair of Geneva wheels driven by a motor-operated program wheel.
