Abstract

Es wird eine Vakuumerzeugervorrichtung (1) und ein zu deren Betreiben geeignetes Verfahren vorgeschlagen. Eine Ejektoreinrichtung (27) ist mit ihrem Einlass an einen ein Steuerventil (36) aufweisenden Luftversorgungskanal (32) und mit ihrer Saugseite (34) an einen mit einer Sauggreiferanordnung (7) verbundenen Saugkanal (35) angeschlossen, der über ein Ausblasventil (37) zum Belüften der Sauggreiferanordnung (7) mit Luft beaufschlagbar ist. Beide Ventile (36,37) werden durch ein gemeinsames externes Steuersignal gesteuert, mit dessen Beginn das Steuerventil (36) und mit dessen Ende das Ausblasventil (37) geöffnet wird, wobei während der Dauer dieses Steuersignals durch entsprechende Steuerung des Steuerventils (36) ein Saugunterdruck (-p) in der Sauggreiferanordnung (7) aufrecht erhalten wird.

A vacuum generating device (1) and a method suitable for operating it are proposed. An ejector device (27) is connected at its inlet to an air supply channel (32) having a control valve (36) and with its suction side (34) to a suction channel (35) connected to a suction gripper arrangement (7) which is connected via a blow-off valve (37). for ventilating the suction pad assembly (7) can be acted upon with air. Both valves (36,37) are controlled by a common external control signal, with the beginning of the control valve (36) and at the end of the blow-off valve (37) is opened, wherein during the duration of this control signal by appropriate control of the control valve (36) a Suction vacuum (-p) is maintained in the suction pad assembly (7).
