Abstract

The present invention discloses a gripper device using an air-tube. Particularly, the gripper device quickly performs ‘release’ on gripping of a product. The gripper device is designed so that compressed air for griping, which is introduced through a first tube and accumulated in an expansion space of a side wall of the cylindrical air-tube, is instantly discharged to the outside through a second tube that is opened by a reverse movement of a valve and the air-tube. Thus, the ‘release’ is quickly performed to resultantly extremely reduce an operation time of a transfer operation in which gripping, transferring, releasing, and returning of the product are repeated.
