Vacuum generator having means arranged to release the active objects that are driven by high pressure air, is gripped by a vacuum gripper

摘要

A vacuum generator is arranged to supply a vacuum to the vacuum gripper means, the chamber (6) is coupled with a vacuum generator, and as a result of the interruption of the compressed air flow (P), the vacuum gripper means overpressure in order to release the, via a valve (15) actuated by overpressure accumulated in the chamber in order to open a flow connection between the vacuum gripper means (9), the flow connection between the vacuum gripper means (9) is a vacuum generator driven by compressed air that is arranged to be effected. Chamber (6), the flow connection between the ambient atmospheric pressure (11), in a further flow connection (11), connected with the atmosphere as a result of the air pressure in the chamber (6) below the pressure of the ambient atmosphere (11) characterized in that further comprising a one-way valve which is arranged to open (10).
