IPC: B25J15/06
Filed: 2001-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a vacuum generator that can break the vacuum immediately and can perform the suction and release operation of a work piece at high speed. SOLUTION: The vacuum generator includes a control unit 70 that controls on and off of the air feed of compressed air supplied from a supply port 10, a vacuum generation part that produces vacuum at the on status by injecting the compressed air fed into a cylinder 16 through a nozzle 18 and passing through a diffuser spool 20 and then discharging from an exhaust port 40, and a vacuum port 50 connected to the vacuum generation part. The diffuser spool 20 can be moved to the axis direction in the cylinder and together with that, a gap between the outer surface of the diffuser spool and the inside surface of the cylinder is formed to be an auxiliary path for the vacuum destruction. At the air feed on, the diffuser spool 20 moves to the advanced position by the pushing pressure of compressed air and the gap is closed and then the air is sucked from the vacuum port.  At the air feed off, the diffuser spool moves to the backward position and the vacuum destruction becomes possible by passing through the exhaust port 40, the auxiliary path and an inner diameter part of the diffuser spool.
