Abstract
A workpiece conveying apparatus for a pressing machine includes an arm unit including: a first arm; a second arm; a workpiece holding portion configured to hold a workpiece; a first arm drive mechanism; and a second arm drive mechanism. A pipe or the like arranged on an outer side of a second joint is supported at one side thereof by the first arm, and is supported at another side thereof by the second arm. When the first arm and the second arm are bent and stretched between a folded state and an extended state for workpiece conveyance, the pipe or the like is deformed utilizing a holding angle between the first arm and the second arm so that the pipe or the like is arranged so as to prevent swing of the pipe or the like about the second joint at the time of the workpiece conveyance.
