Abstract
Provided is a workpiece transfer apparatus for a press machine including: a workpiece retaining device which is supported by a crossbar extending to be approximately orthogonal to a workpiece transfer direction, and is capable of retaining and releasing a workpiece; a guiding device which supports and guides the workpiece retaining device so that the workpiece retaining device is slidable along a longitudinal direction of the crossbar; a driving device which drives the workpiece retaining device supported and guided by the guiding device so that the workpiece retaining device is moved along the longitudinal direction of the crossbar; and a brake device which acts in a path different from a path of the driving device, the brake device being capable of fixing and releasing a position of the workpiece retaining device with respect to the longitudinal direction of the crossbar.
