Bei Querschneideinrichtungen ist es bekannt, am Gegenzylinder nebeneinander mehrere Abstreifer anzuordnen, die die geschnittenen Bogen vom Gegenzylinder ableiten. Diese werden dann beispielsweise mittels Bändersystemen auf einen Sammelzylinder weitertransportiert.In cross-cutting devices, it is known to use the counter cylinder to arrange several wipers next to each other, which the cut Derive arc from counter cylinder. These are then, for example transported to a collecting cylinder by means of conveyor systems.

Bei solch einer Einrichtung besteht die Gefahr von Stopfern am Spalt, mit dem die Abstreifer am Mantel des Gegenzylinders angestellt sind.With such a facility, there is a risk of blockages on Gap with which the wipers on the jacket of the counter cylinder are employed.

Aufgabe der Erfindung ist es, eine Einrichtung zum Querschneiden von Bahnen mit einem Schneidleisten tragenden Gegenzylinder und einem oder mehreren an diesem angeordneten Messerwalzen und mehreren nebeneinander in Achsrichtung am Gegenzylinder angestellten Abstreifern zum Ableiten des geschnittenen Bogens zu schaffen, bei der die geschnittenen Bogen zuverlässig von dem Gegenzylinder abgeführt werden.The object of the invention is to provide a device for cross cutting Paths with a counter cylinder and a cutting bar or several knife rollers arranged thereon and several placed side by side in the axial direction on the counter cylinder To create scrapers for deriving the cut sheet which reliably cut the sheets from the counter cylinder be dissipated.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Die Einrichtung vermeidet einen Spalt zwischen der Mantelfläche des Gegenzylinders und den Abstreifern und damit Stopfer bei der Bogenableitung.This object is achieved by the characterizing features of the claim 1 solved. The device avoids a gap between the Lateral surface of the counter cylinder and the wipers and thus Stuffer in the arc derivation.

Die Schneidleisten sind vorteilhaft zurückbewegbar, wenn erfindungsgemäß jede Schneidleiste auf einem sich auf einer Kurvenscheibe abstützenden, im Körper des Gegenzylinders 1 schwenkbar gelagerten Hebel befestigt ist.The cutting strips can advantageously be moved back if, according to the invention, each cutting strip is fastened on a lever which is supported on a cam disc and is pivotably mounted in the body of the counter-cylinder 1 .

Die Erfindung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden. Die zugehörige Zeichnung zeigt eine Querschneideeinrichtung, schematisch, in der Seitenansicht. Die dargestellte Querschneideeinrichtung enthält einen Gegenzylinder 1, an dem eine erste und eine zweite Messerwalze 2; 3 mit Umfängen von jeweils der Abschnittlänge angeordnet sind. Sie tragen jeweils ein Schneidmesser 4; 5. Das Schneidmesser 4 hat eine Schneidkante mit Unterbrechungen, in denen eine Gruppe von am Gegenzylinder 1 anliegenden bewegten Bändern 6 den Messerbereich passiert. Das Schneidmesser 5 weist ebenfalls Unterbrechungen auf, die zu denen des Schneidmessers 4 versetzt sind. In ihnen passiert eine Gruppe von am Gegenzylinder 1 anliegenden, bewegten Bändern 7 den Messerbereich. Die Bänder 6; 7 werden mittels einer gemeinsamen Bandwalze 8 umgelenkt. Die Zapfen der Messerwalzen 2; 3 sowie der Bandwalze 8 tragen jeweils ein Zahnrad 9 bis 11. Die Messerwalze 2 steht mittels des Zahnrades 9 mit einem Zahnrad 12 des Gegenzylinders 1 in Antriebsverbindung. Das Zahnrad 11 der Bandwalze 8 steht ebenfalls mit dem Zahnrad 12 in Eingriff und treibt über ein Verschiebezwischenrad 13 und das Zahnrad 10 die Messerwalze 3 an. Das Verschiebezwischenrad 13 ermöglicht eine Synchronisation vom ersten Schnitt zum zweiten Schnitt.The invention will be explained in more detail using an exemplary embodiment. The accompanying drawing shows a cross cutting device, schematically, in a side view. The cross cutting device shown contains a counter cylinder 1 on which a first and a second knife roller 2 ; 3 are arranged with circumferences each of the section length. They each carry a cutting knife 4 ; 5 . The cutting knife 4 has a cutting edge with interruptions, in which a group of moving belts 6 resting on the counter cylinder 1 passes the knife area. The cutting knife 5 also has interruptions which are offset from those of the cutting knife 4 . In them, a group of moving belts 7 resting on the counter cylinder 1 passes the knife area. The tapes 6 ; 7 are deflected by means of a common belt roller 8 . The pins of the knife rollers 2 ; 3 and the belt roller 8 each carry a gear 9 to 11 . The knife roller 2 is by means of the gear wheel 9 with a gear 12 of the anvil cylinder 1 in drive connection. The gear 11 of the belt roller 8 is also in engagement with the gear 12 and drives the knife roller 3 via a sliding intermediate gear 13 and the gear 10 . The sliding intermediate gear 13 enables synchronization from the first cut to the second cut.

Der Gegenzylinder 1 trägt mehrere Schneidleisten 14 mit einem jeweiligen Umfangsabstand zueinander in Höhe der Abschnittlänge. Jede Schneidleiste 14 ist auf einem Hebel 15 befestigt, der schwenkbar im Körper des Gegenzylinders 1 gelagert ist und sich auf einer Kurvenscheibe 16 abstützt. Der Gegenzylinder 1 weist in Umfangsrichtung mehrere Nuten 17 auf, in die jeweils ein Abstreifer 18 hineinragt. An die Abstreifer 18 schließt sich eine Gruppe bewegter Bänder 19 an.The counter cylinder 1 carries a plurality of cutting strips 14 with a respective circumferential distance from one another at the level of the section length. Each cutting bar 14 is attached to a lever 15 which is pivotally mounted in the body of the counter cylinder 1 and is supported on a cam disk 16 . The counter cylinder 1 has a plurality of grooves 17 in the circumferential direction, into each of which a wiper 18 projects. A group of moving belts 19 adjoins the wipers 18 .

Die querzuschneidende Bahn 20, beispielsweise eine mittels eines Falztrichters längsgefalzte, bedruckte Bahn 20 läuft mit Unterstützung der Bänder 21 in den Spalt zwischen Gegenzylinder 1 und Bändern 6 ein. In der Zentralen des Gegenzylinders 1 und des Messerzylinders 2 wird die Bahn 20 von dem Schneidmesser 4 in Verbindung mit einer Schneidleiste 14 teilgeschnitten, d. h. die Unterbrechungen des Schneidmessers 4 hinterlassen in der Schnittlinie auf der Bahn 20 Stege, die erst beim Schnitt mittels des Schneidmessers 5 der zweiten Messerwalze 3 in Verbindung mit der gleichen Schneidleiste 14 getrennt werden. Die nunmehr erhaltenen Bogen werden von den Abstreifern 18 vom Gegenzylinder 1 abgeleitet und mittels der Bänder 7 und 19 weitertransportiert, beispielsweise zu einem Sammelzylinder. Die Schneidleisten 14 werden im Bereich der Abstreifer 18 zurückgesteuert. Dies erfolgt beim Ablaufen der Kurvenrollen 22 der Hebel 15 auf der feststehenden Kurvenscheibe 16 bei der Drehung des Gegenzylinders 1.The web 20 to be cut transversely, for example a printed web 20 folded lengthwise by means of a folding former, runs into the gap between counter cylinder 1 and webs 6 with the support of the webs 21 . In the center of the counter cylinder 1 and the knife cylinder 2 , the web 20 is partially cut by the cutting knife 4 in conjunction with a cutting bar 14 , ie the interruptions of the cutting knife 4 leave webs in the cutting line on the web 20 , which are only cut when the cutting knife 5 is used the second knife roller 3 in connection with the same cutting bar 14 are separated. The sheets now obtained are derived by the scrapers 18 from the counter cylinder 1 and transported further by means of the belts 7 and 19 , for example to a collecting cylinder. The cutting strips 14 are controlled back in the area of the wipers 18 . This takes place when the cam rollers 22 of the levers 15 run on the fixed cam disk 16 when the counter-cylinder 1 rotates.

Im Ausführungsbeispiele sind am Gegenzylinder zwei Messerwalzen angeordnet. Ebenfalls zum Schutzumfang des Patentes gehören auch Querschneideinrichtungen, bei denen sich nur eine Messerwalze am Gegenzylinder befindet.In the exemplary embodiment, two knife rollers are on the counter cylinder arranged. The scope of protection of the patent also includes Cross cutting devices, in which only one knife roller on Counter cylinder is located.
