<p>Vacuum system (10) comprises vacuum gripping devices for gripping workpieces and/or vacuum component both having an energy generating device (22) for generating new electrical energy which is not stored in the vacuum system to operate a module (8) consuming electrical energy. Preferred Features: The module consuming electrical energy is a vacuum generator, a sensor, an emitter, a display, an actuator or a data storage unit. The sensor is a vacuum sensor, a flow sensor, an air amount sensor, a counter, a movement sensor, a temperature sensor, a distance sensor, a presence sensor or a power sensor. The vacuum gripping device is a suction gripper, a vacuum tensioning system or other device for directly or indirectly holding a workpiece.</p> |
