A workpiece conveying device comprising:
- a traveling platform to move on traveling rails;
- a workpiece sucker arranged below the traveling platform;
- a vertical drive guide, including a shaft, provided on the traveling platform, to vertically drive the workpiece sucker by vertically moving the shaft;
- a fork to slide so as to sandwich the workpiece sucker;
- and
- a fork driver provided on the shaft between the workpiece sucker and the traveling platform and to drive the fork, wherein
- the fork includes a pair of holders that performs an opening movement to be guided by a groove formed in the fork driver and to be separated from each other when the workpiece sucker vertically moves and performs a closing movement to be guided by the groove and to be closer to each other when the workpiece sucker does not vertically move, and
- the pair of holders include a slider that is positioned on an upper side of the fork driver when the workpiece sucker does not vertically move.
