Abstract

Die Vorrichtung zur Abnahme von Bogen (21) von einem Stapel (22) und zum Transport der Bogen (21) weg vom Stapel (22) hat einen Zahnriemen (1), der zwei seitliche Zahnringe (2) mit einer dazwischenliegenden Führungsfläche (3) und auf der gegenüberliegenden Seite entsprechend der Zahnteilung angeordnete, quer verlaufenden Nuten (5) aufweist, die über einen zentralen Durchbruch (6) mit der Führungsfläche (3) verbunden sind. Der Zahnriemen (1) wird um ein Saugrad (7) geführt, das für den Zahneingriff entsprechende Zahnringe (9) und dazwischen einen Mittelsteg (13) mit einer Führungsbahn (10) für den Eingriff mit der Führungsfläche (3) aufweist. Der Zahnteilung entsprechend sind in dem Saugrad (7) Anschlußleitungen (14) ausgebildet, die sich von einer Stirnfläche (15) mit entsprechender Winkelteilung zur Führungsbahn (10) zu einer fluchtenden Ausrichtung mit den Durchbrüchen (6) erstrecken. Bogenseitig ist der einen Stirnfläche (15) des Saugrades (7) ein Vakuumblock (16) mit einem Vakuumkanal (17) zugeordnet, über den taktgesteuert eine Verbindung mit einer Vakuumquelle (12) so herstellbar ist, daß durch das Vakuum in der Anschlußleitung (14) im Ansaugpunkt (24) eine Ansaugkraft erzeugt wird, die den obersten Bogen (21) vom Stapel (22) gegen den Zahnriemen (1) für dessen Abtransport zieht.

Figure 00000001
The device for removing sheets (21) from a stack (22) and for transporting the sheets (21) away from the stack (22) has a toothed belt (1), which has two lateral toothed rings (2) with an intermediate guide surface (3) and has transverse grooves (5) which are arranged on the opposite side in accordance with the tooth pitch and which are connected to the guide surface (3) via a central opening (6). The toothed belt (1) is guided around a suction wheel (7), which has toothed rings (9) corresponding to the tooth engagement and between them a central web (13) with a guide track (10) for engagement with the guide surface (3). Corresponding to the tooth pitch, connecting lines (14) are formed in the suction wheel (7), which extend from an end face (15) with a corresponding angular pitch to the guideway (10) to an aligned alignment with the openings (6). On the arc side, one end face (15) of the suction wheel (7) is assigned a vacuum block (16) with a vacuum channel (17), via which a connection to a vacuum source (12) can be clock-controlled so that the vacuum in the connecting line (14 ) a suction force is generated in the suction point (24), which pulls the uppermost sheet (21) from the stack (22) against the toothed belt (1) for its removal.
