ABSTRACT:
A transfer apparatus includes a stationary base, a swivel rotatable around a vertical rotation axis, a linear movement mechanism supported by the swivel, a hand supported by the linear movement mechanism for transferring a work along a horizontal path, a driving power source in the stationary base, and a transmission shaft arranged along the rotation axis for transmitting driving force from the driving power source to the linear movement mechanism. The linear movement mechanism includes a driving mechanism and a guide rail for movably supporting the hand. The driving mechanism has a plurality of pulleys, including a driving pulley supported rotatably around a horizontal axis, and an output belt wound around the plurality of pulleys for reciprocal movement within a predetermined section extending parallel to the movement path. The hand is connected to the output belt via a connection member.
