Abstract
The invention relates to a system (10) for handling workpieces, with a handling device (12) which comprises at least one vacuum gripper (16) for drawing a workpiece in by suction, with at least one vacuum generator (26) that can be operated by the supply of compressed air for supplying the vacuum gripper (16) with vacuum, with at least one controllable control valve (28) by which the supply of compressed air to the vacuum generator (26) can be controlled, wherein the control valve (28) is associated with a control device (30) for the proper control of the control valve (28 as required. The handling device comprises an evaluation unit (32) for evaluating operating data of the vacuum generator (26) and/or for evaluating operating data of the handling device (12) as well as for generating control signals as a function of the evaluated operating data, wherein the evaluation unit (32) is arranged on the handling device (12), and wherein the control device (30) controls the control valve (28) as a function of the control signals transmitted from the evaluation unit (32).
