ABSTRACT:
A workpiece transfer device includes a mounting frame assembly having an upper fixed frame and an inner subframe slidably mounted to the fixed frame. The inner subframe supports a gear rack on its upper surface and a separate conveying system within its frame. A drive unit is mounted on top of the fixed frame and includes idler rollers and a drive gear. The drive gear engages the gear rack thereby moving the whole inner subframe assembly, including the conveyor system in a horizontal path between two presses. As the inner subframe moves along a horizontal plane, a locking plate assembly prevents the conveyor belt from traveling with the inner subframe. The end gears in the conveyor rotate along the stationary belt forcing a workpiece carrier to move from one end of the conveyor system to the opposite end in the same direction as the inner subframe. Therefore, as the inner subframe moves in a horizontal path, the carrier is simultaneously moved along the same path.
