Description

Die Erfindung betrifft eine Querschneidvorrichtung für Textilbahnen mit einem über die Breite der zu scnneidenden Textilbahn mittels Riemenantrieb hin- und herge­ führten scheibenförmigen Messer, das ebenfalls von einem Riemen angetrieben ist.The invention relates to a cross cutting device for textile webs with an over the width of the textile web to be cut back and forth by means of a belt drive led disc-shaped knife, which is also driven by a belt.

Derartige Schneidvorrichtungen werden bei der Herstellung von textilen Erzeug­ nissen wie Handtüchern, Servietten, Taschentüchern und dergleichen vielfach ver­ wendet. Dabei besteht die Forderung, den Schneidvorgang nicht nur exakt sondern auch in einer möglichst kurzen Zeit ausführen zu können, um die Leistungsfähigkeit der Maschine zu steigern. Sitzt nun - wie üblich - der zum Drehantrieb des Messers dienende Motor unmittelbar auf der Messerachse, so muß in den Umkehr­ stellen des hin- und hergehenden Längentransports des Messers jeweils eine verhält­ nismäßig große Masse beschleunigt werden, was Zeit und Kraft erfordert. Vor allem aber mußte der Drehantriebsmotor abgebremst werden, damit er beim Rück­ transport in der entgegengesetzten Drehrichtung laufen konnte. Das bedingte erheb­ liche Zeitverluste. Ein weiterer Nachteil dieser bekannten Ausführung bestand darin, daß der seitlich des Messers sitzende Motor für dessen Drehantrieb einen großen Raumbedarf, insbesondere in einer Richtung erforderte, in der man wenig Platz hatte, beziehungsweise Platz sparen wollte. Such cutting devices are used in the manufacture of textile products such as towels, napkins, handkerchiefs and the like turns. There is a requirement that the cutting process not only be precise but also to be able to perform in as short a time as possible in order to improve performance to increase the machine. Now sits - as usual - the one that drives the Knife-serving motor directly on the knife axis, so must reverse of the reciprocating length transport of the knife behaves one large masses are accelerated, which takes time and effort. In front but everything had to be braked the rotary drive motor so that it on the back transport could run in the opposite direction of rotation. The conditional wasted time. Another disadvantage of this known embodiment was in that the motor, which sits on the side of the knife, drives a rotary drive large space requirement, especially in a direction in which one needed little Had space, or wanted to save space.  

Eine solche Vorrichtung zeigt die DE-AS 24 24 632. Der Motor für den Antrieb des Scheibenmessers sitzt mit diesem auf einem Schlitten, der mittels eines Bandantriebs über die Breite der Textilbahn hin- und herbewegbar ist. Hierzu ist seitlich der Vorrichtung ein weiterer umsteuerbarer Motor vorgesehen. Dies hat den Nachteil, daß der Schlitten mit dem Motor für das Scheibenmesser eine vergleichs­ weise große Masse aufweist, die hin- und herbewegt werden und an den Umkehr­ punkten abgebremst werden muß.DE-AS 24 24 632 shows such a device. The motor for the drive the disc knife sits with it on a carriage, which by means of a Belt drive can be moved back and forth across the width of the textile web. This is Another reversible motor is provided to the side of the device. This has the Disadvantage that the slide with the motor for the disc knife a comparison wise has large masses that are reciprocated and reverse points must be slowed down.

Außerdem wird auch das fliegende Stromleitungskabel für den Messermotor als nachteilig empfunden.In addition, the flying power cable for the knife motor is used as felt disadvantageous.

Die Erfindung geht von einem Riemenantrieb sowohl für den Antrieb des Scheiben­ messers als auch für die Hin- und Herbewegung aus, weil erkannt wurde, daß ein solches, intern bekanntes Antriebssystem wesentliche Vorteile bringt.The invention is based on a belt drive for both the drive of the pulleys knife as well as for the back and forth movement because it was recognized that a such internally known drive system brings significant advantages.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbesserung dahingehend zu schaffen, daß der Schneidvorgang in kurzer Zeit und ohne großen Kraftaufwand vor sich gehen kann, wobei gleichzeitig der Platzbedarf für die Schneidvorrichtung verringert wird.The object of the invention is to improve this create that the cutting process in a short time and without great effort can go, while at the same time the space required for the cutting device is reduced.

Zur Lösung dieser Aufgabe dienen die im Hauptanspruch gekennzeichneten Merk­ male. Die Unteransprüche enthalten zweckmäßige weitere Ausbildungen.To solve this problem serve the marked in the main claim times. The sub-claims contain useful further training.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Schneidvor­ richtung dargestellt. In the drawing is an embodiment of the cutting device according to the invention direction shown.  

Ein scheibenförmiges Messer 1 ist in einem Block 4 mit seiner Messernabe 6, mit der es fest verbunden ist, drehbar gelagert. Der Schnitt erfolgt zwischen dem Messer 1 und einem unter diesem angeordneten Untermesser. In dem Block 4 sind außerdem noch zwei Umlenkrollen 5 gelagert, die zur Führung eines endlosen ersten Riemens 2 dienen. Dieser Riemen 2 umschlingt die Messernabe 6 und be­ wirkt so einen zuverlässigen Antrieb des Messers 1. Der erste Riemen 2 läuft über die ganze Länge der Maschine, wobei der Block 4 auf einer Schiene 8 mit Gleit­ stücken 7 geführt ist. Der erste Riemen 2 wird von einem eigenen Motor 3 ange­ trieben. Unabhängig von dem ersten Riemen 2 ist ein zweiter endloser Riemen 9 vorgesehen, der ebenfalls über die ganze Maschinenbreite läuft und von einem eigenen Motor 11 angetrieben wird. Dieser zweite Riemen 9 bewirkt ausschließlich den Quertransport des Blockes 4 mit dem Messer 1, wobei der Block 4 mittels einer Klemmvorrichtung 10 fest mit dem Riemen 9 verbunden ist.A disk-shaped knife 1 is rotatably mounted in a block 4 with its knife hub 6 , with which it is firmly connected. The cut is made between the knife 1 and a lower knife arranged below it. In the block 4 there are also two deflection rollers 5 which are used to guide an endless first belt 2 . This belt 2 wraps around the knife hub 6 and thus acts as a reliable drive of the knife 1 . The first belt 2 runs over the entire length of the machine, the block 4 being guided on a rail 8 with sliding pieces 7 . The first belt 2 is driven by its own motor 3 . Regardless of the first belt 2 , a second endless belt 9 is provided, which also runs over the entire width of the machine and is driven by its own motor 11 . This second belt 9 exclusively effects the transverse transport of the block 4 with the knife 1 , the block 4 being firmly connected to the belt 9 by means of a clamping device 10 .
