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.
Claims8
A gripper device using an air-tube, comprising:
- a gripper housing (11) comprising a supply tube (15) comprising a first tube (16) and a second tube (17), each of which extends in a vertical direction, and a cover part (18) extending downward from an outer side of the supply tube (15);
- a valve (12) disposed between the first tube (16) and the second tube (17) in the supply tube (15) to move upward or downwards based on a pressure direction of a compressed air, thereby closing the first tube (16) or the second tube (17);
- an air-tube (13), as a cylindrical member spaced apart form an inner wall of the cover part (18) with a space (S) therebetween, which communicates with the second tube (17) and in which a plurality of grip expansion portions (19) are formed on a side wall of the air-tube (13);
- and
- a flow path (14) defined at one side of the supply tube (15) to connect the first tube (16) and the space (S) or the space (S) and the second tube (17) based on a movement direction of the valve (13).
