Abstract
A transfer apparatus includes a stationary base, a swivel rotatably supported by the stationary base, and a linear movement mechanism supported by the swivel and including guide rails. Hands for carrying works are supported by the guide rails and movable along a horizontal straight travel path by the operation of the linear movement mechanism. A heat reflector is provided between the hands and the guide rails. A refrigerant circulation channel includes annular spaces for ensuring constant communication between a passage on the side of the stationary base and a passage on the side of the swivel. The refrigerant circulation channel includes cooling pipes held in contact with the heat reflector.
Claims7
A transfer apparatus comprising:
- a stationary base;
- a swivel rotatably supported by the stationary base;
- a linear movement mechanism supported by the swivel and including a guide rail;
- a hand supported by the guide rail for transferring a work along a horizontal straight travel path by operation of the linear movement mechanism;
- a heat reflector for reflecting heat from the hand, the heat reflector being arranged at least between the hand and the guide rail;
- and
- a refrigerant circulation channel extending through both the stationary base and the swivel;
- wherein the refrigerant circulation channel includes a stationary base side passage provided at the stationary base, a swivel side passage provided at the swivel, and a connection space for providing communication between the stationary base side passage and the swivel side passage regardless of a rotational position of the swivel relative to the stationary base, and wherein the refrigerant circulation channel includes a portion held in contact with the heat reflector.
