Abstract
Under pressure handling device comprising an under pressure generator, a device for controlling the under pressure and several grippers which engage on a work piece to be handled, wherein each gripper is provided with a device for controlling the under pressure, a sensor for detecting state variables on the gripper and an evaluation electronics to which the device for controlling the under pressure and the sensor are connected.
Claims9
An under pressure device for handling a work piece, the device comprising:
- an under pressure generator;
- at least one gripper to engage the work piece to be handled;
- a separate under pressure regulation means disposed on each one of said at east one gripper to control an under pressure of that gripper, each of said under pressure regulation means communicating with said under pressure generator, wherein each of said under pressure regulation means comprises a means for controlling at least one of an under pressure and a volume flow of that gripper on which it is disposed, a sensor for detecting operating conditions of that gripper, and an evaluation electronics communicating with said controlling means and said sensor to control at least one of said under pressure and said volume flow in dependence on said operating conditions as detected by said sensor, wherein said under pressure controlling means, said sensor, and said evaluation electronics of each said gripper are accommodated in a vacuum fitting directly connected to that gripper.
