ABSTRACT:
A system and method for controlling movement of a transfer system (22) between operable and serviceable positions in a manufacturing system such as a stamping press (10) includes a crank arm (60) and a plurality of swing arms (66, 76). The swing arms (66, 76) connect the crank arm (60) to the transfer system (22) and define a plurality of pivot connections with each other so as to allow controlled movement of the transfer system (22) between operable and serviceable positions when the crank arm (60) is driven. A plurality of gears (82, 84, 86, 88) including a reference gear (82) fixed to the stamping press (10) and an object gear (84) fixed to the transfer system (22) are used to control transfer system attitude during movement. Drive means (94, 96) interconnect the plurality of gears (82, 84, 86, 88) to rotate the transfer system (22) by rotating the object gear (84) together with the transfer system (22) as the crank arm (60) is driven.
