Abstract
A workpiece transfer apparatus includes: a feed driving mechanism that drives a transfer bar in a workpiece transfer direction; and a lift/clamp driving mechanism that drives the transfer bar in a lift direction and a clamp direction. The lift/clamp driving mechanism includes: a support of the transfer bar; first and second carriers movable in the clamp direction; first and second carrier driving mechanisms that drive the first and second carriers; a parallel link that rotatably connects the first carrier with the support; and a driving link that rotatably connects a first link of the parallel link and the second carrier. A first guide that guides the first carrier and a second guide that guides the second carrier are parallel to each other and are shifted from each other in the workpiece transfer direction.
