According to this, when the holding member 23 holds the workpiece W, it is possible to prevent the holding surface 23a of the holding member 23 from rubbing against the surface of the workpiece W. Further, when a plurality of transfer mechanisms 2 are provided, when the workpiece W is passed through a predetermined transfer mechanism 2 in order to hold the workpiece W by the holding member 23 of the next transfer mechanism 2, the predetermined transfer mechanism 2. The holding member 23 can prevent the workpiece W from being inadvertently held.
  • the holding member 23 has a holding surface 23a for holding the workpiece W formed on a flat surface.
  • the holding surface 23a for holding the workpiece W is loosely shaped like a mountain. You may use what was formed in the curved surface. According to this, since the work W held by the holding member 23 is stretched, it is possible to prevent the work W from fluttering or dripping during the rotational conveyance of the work W by the holding member 23.
  • the shape and size of the holding member 23 are not particularly limited, but are formed in a shape and size that do not interfere with the claw member 32 and other members when the workpiece W is stacked on the stacking table 31. Is preferred.
  • the present invention is not necessarily applied to the battery material laminating apparatus. That is, the holding member 23 holds the workpiece W at a predetermined location, and after the mover 22 rotates and conveys the workpiece W as it travels along the traveling path of the stator 21, the workpiece W is moved to another location. As long as it has the transfer mechanism 2 (battery material transfer apparatus) mounted in the place, you may apply to the other apparatus related to battery manufacture.
  • the transfer mechanism 2 battery material transfer apparatus
