Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb eines Saugbandvorschubmechanismus, bei dem der oberste Bogen eines Stapels gewellt wird, mit einer Überdrucklufttrennvorrichtung (40) während eines Einzugszyklus, wobei die Unterdruckluft und die Überdruckluft anhand eines Unterdruckluftventils (38) und eines Überdruckluftventils (60) gesteuert werden, wobei das Papier mit Hilfe von mindestens einem Band (36) abtransportiert wird, das aktiviert wird, wenn eine Zufuhrkupplung (56) betätigt wird, und die Unterdruckluft aktiviert wird, wenn der Einzugszyklus beginnt, und deaktiviert wird, wenn die Zufuhrkupplung (56) getrennt wird, wobei das Verfahren den Schritt des Pulsens der Überdrucklufttrennvorrichtung (40) durch Aktivieren und Deaktivieren der Überdrucklufttrennvorrichtung (40) während des Einzugszyklus umfasst.

Figure 00000001
The invention relates to a method for operating a suction belt feed mechanism, in which the top sheet of a stack is corrugated, with an overpressure air separation device (40) during a feed cycle, the underpressure air and the overpressure air being controlled by means of an underpressure air valve (38) and an overpressure air valve (60) wherein the paper is carried away by means of at least one belt (36) which is activated when a feed clutch (56) is actuated and the vacuum air is activated when the feed cycle begins and is deactivated when the feed clutch (56) is separated, the method comprising the step of pulsing the pressurized air separation device (40) by activating and deactivating the pressurized air separation device (40) during the pull-in cycle.
