Abstract
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.
