Abstract
An apparatus for elevating a workpiece includes a transfer bar movable between a first position and a second position, and a support member having a cam surface with a first end and a second end. The cam follower is engageable with the cam surface for supporting the transfer bar with respect to the support member as the cam follower moves along the cam surface between the first end and the second end. When the transfer bar is in the first position, the cam follower is adjacent the first end of the cam surface. When the transfer bar is in the second position, the cam follower is adjacent the second end of the cam surface. A driving mechanism is provided for moving one of the cam follower and the cam surface relative to one another between the first end and the second end of the cam surface. The elevating apparatus can be used in a multi-station machining line where at least one workpiece to be machined is transported on at least one transfer bar from one station to another. The transfer bar is elevated to a first position for transportation of the workpiece between the stations, and is lowered to a second position when the workpiece reaches a station.
