Abstract
A workpiece transport device capable of improving a workpiece transport speed to increase productivity is provided. The workpiece transport device transports a workpiece pressed by a press machine. The workpiece transport device includes a base portion, a crossbar that holds the workpiece, a parallel mechanism, and a motor. The parallel mechanism is supported on the base portion. The parallel mechanism is configured to change a position of the crossbar relative to the base portion by operating in a plane defined by a transport direction in which the workpiece is transported and an up-down direction. The motor generates a driving force for driving the parallel mechanism. The motor is mounted on the base portion.

A workpiece transport device that transports a workpiece pressed by a press machine, the workpiece transport device comprising:
- a base portion;
- a holding portion that holds the workpiece;
- a parallel mechanism supported on the base portion and configured to change a position of the holding portion relative to the base portion by operating in a plane defined by a transport direction in which the workpiece is transported and an up-down direction;
- and
- an actuator that is mounted on the base portion and generates a driving force for driving the parallel mechanism, wherein
- the parallel mechanism includes a first arm portion and a second arm portion that are in parallel with each other, the first arm portion includes a first lever attached to the base portion and a first link having a base end attached to the first lever and a tip end to which the holding portion is attached, and the second arm portion includes a second lever attached to the base portion and a second link having a base end attached to the second lever and a tip end coupled to the first link, and
- the first arm portion has a higher torsional rigidity than the second arm portion.
