Abstract

Um einen oder mehrere relativ zur Stapeloberfläche periodisch bewegte Saugabnehmer (2) in einfacher Weise mit Antriebsenergie versorgen zu können, ist der Saugab­ nehmer (2) an ein Luftvolumen (16) mit im wesentlichen konstant bleibendem Unteroder Überdruck angeschlossen, und in die Verbindungsleitung (15) zwischen dem Saugab­ nehmer und dem Luftvolumen ist eine den Saugabnehmer periodisch mit der Außenluft verbindende Ventilanordnung (10) eingeschaltet. Die Ventilanordnung (10) kann von einem unter der Wirkung einer Rückstellkraft stehenden Steuerkol­ ben (14), von einem pneumatischen Mehrwegeventil mit regelbarer Frequenz oder von einem an einen regelbaren Frequenzgenerator angeschlossenen Magnetventil gebildet werden. Mit Hilfe einer Regeleinrichtung für den Querschnitt der Entlüftungsöffnung läßt sich eine nach dem Einschalten des beweglichen Saugabnehmers von Hub zu Hub bis zum völligen Stillstand kleiner werdende Amplitude der Saugab­ nehmerbewegung erzeugen. To one or more relative to the stack surface periodically moving suction cups (2) in a simple manner To be able to supply with drive energy is the suction participant (2) to an air volume (16) with essentially constant negative or positive pressure connected, and in the connecting line (15) between the suction and the air volume is one of the suction cups valve arrangement connecting periodically with the outside air (10) switched on. The valve arrangement (10) can be from a control column under the action of a restoring force ben (14), of a pneumatic multi-way valve with adjustable frequency or from one to one adjustable Frequency generator connected solenoid valve formed will. With the help of a control device for the cross section the vent can be opened after switching on of the movable suction cup from stroke to stroke to complete standstill, decreasing amplitude of suction generate slave motion.
