Description

Gegenstand der Erfindung ist eine Vorrichtung zum Lär gsschneiden von flachen, bahnförmigen. Materialien, insbesondere Folier.The invention relates to a device for Lär gsschneid flat, web-shaped. Materials, especially foil.

Es ist bekannt, daß solche bahnförmige Materialien mit Hilfe von Klingen, die durch die Folienbahn in eine Nut einer folie. führenden Walze oder in einen Spalt zwischen zwei die Folienbahn tragenden Walzen eintauchen, auf die gewünschte Breite zugeschnitten wrrden können. Dieses Zuschneiden kann aber auch mit verschiedenen gestalteten Messern, wie z.B. Rundmessern, durchgeführt werden. Nicht nur, daß bei jeder dieser bekannten Schnittarten nicht immer der gewüschte exakte Schnitt erreicht werden kann, tritt auch ein großem Verschleiß der Schnittkanten der Schneidwerkzeuge durch die gegenseitige Bewegung dieser Maschinenteile und unter dem Einfluß des Schnittdruckes auf. Außerdem wird für das Umstellen auf andere Schnittbreiten ein erheblicher zeitlicher Aufwand benötigt.It is known that such sheet-like materials with the aid of blades which pass through the film web into a groove in a film. dipping roller or into a gap between two rollers carrying the film web, which could be cut to the desired width. This cutting can also be done with different designed knives, e.g. Circular knives. Not only does the desired exact cut not always be achieved with each of these known cutting types, there is also a great wear on the cutting edges of the cutting tools due to the mutual movement of these machine parts and under the influence of the cutting pressure. In addition, a considerable amount of time is required to switch to other cutting widths.

Aufgabe der Erfindung ist ein möglichst geringer Verschleiß, eine möglichst große Unfallsicherheit, eine möglichst kurze Umrüstzeit und eine exakte Schnittführung an einer Schneidvorrichtung der genannten Art.The object of the invention is the least possible wear, the greatest possible safety against accidents, the shortest possible changeover time and an exact cut on a cutting device of the type mentioned.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß ein an einer ersten Halterung sitzendes Scherplättchen oberhalb und ein an einer zweiten Halterung sitzendes Scherplättchen unterhalb des zu schneidenden Materials angeordnet ist und daß die parallel zueinander ausgerichteten Schneiden der Scherplättchen einander im Schneidbereich unter Vorspannung berühren.This object is achieved according to the invention in that a shear plate seated on a first holder is arranged above and a shear plate seated on a second holder underneath the material to be cut, and in that the cutting edges of the shaving plate aligned parallel to one another touch each other in the cutting area under prestress.

Die Erfindung unterscheidet insofern vom Stand der Technik, als ein Scherenschnitt zwischen im wesentlichen feststehenden Scherplättchen erzeugt wird. Ein Gleiten der Scherplättchen aneinander erfolgtThe invention differs from the prior art in that a scissor cut is produced between essentially fixed shear plates. The shear plates slide against each other

nicht, so daß die Abnutzung der Scherplättchen weitgehend herabgesetzt wird. Da dir Scherplättchen feststehen, ergibt sich eine exakte und gerade Schnittführung.not, so that the wear of the shear plates is largely reduced. Since you have fixed shear plates, you get an exact and straight cut.

In Weiterbildung der Erfindung wird die Schnittwirkung dadurch verbessert, daß die Schneiden der Scherplättchen einen Keilwinkel von 70 - 90° miteinander bilden.In a further development of the invention, the cutting effect is improved in that the cutting edges of the shear plates form a wedge angle of 70-90 ° with one another.

Das Einführen der Materialbahn wird dadurch erleichtert, daß mindestens eine Halterung schwenkbar auf einer Welle angeordnet ist.The introduction of the material web is facilitated in that at least one holder is arranged pivotably on a shaft.

Damit sich das schwenkbare Scherplättchen beim Einschwenken sicher in die Materialbahn einschneidet, ist vorgesehen, daß wenigstens ein Scherplättchen an einer seiner beiden Schmalseiten einen Anschliff und eine Schnittkante aufweist.So that the pivotable shear plate cuts securely into the material web when it is swiveled in, it is provided that at least one shear plate has a bevel and a cutting edge on one of its two narrow sides.

Durch Verlagerung des Schneidpunktes läßt sich die Abnutzung der Scherplättchen dadurch vergleichmäßigen, daß mindestens eine Halterung jeweils auf einer Welle hin- und herschwenkbar antreibbar ist. Durch langsame periodische Verschwenkung kann man so den Schneidpunkt nahezu über die gesamte Länge der Scheidkante verschieben und die Abnutzung vergleichmäßigen.By shifting the cutting point, the wear of the shear plates can be evened out in that at least one holder can be driven to pivot on a shaft. By slowly swiveling periodically, the cutting point can be moved almost over the entire length of the cutting edge and the wear can be evened out.

Eine Verschiebung des Schneidpunktes über einen großen Bereich des feststehenden Scherplättchens wird dadurch sichergestellt, daß die Schneide des schwenkbar angeordneten Scherplättchens exzentrisch zur Achse der Welle ausgerichtet ist.A displacement of the cutting point over a large area of the fixed shear plate is ensured in that the cutting edge of the pivotably arranged shear plate is aligned eccentrically to the axis of the shaft.

Eine Ausführungsform der Erfindung wird im Folgenden unter Bezugnahme auf die anliegenden Zeichnungen erläutert, in denen darstellen:

  • Fig. 1 einen Schnitt durch die Schneidvorrichtung parallel zur Bahnführung,
  • Fig. 2 einen Querschnitt zu Fig. 1,
  • Fig. 3 eine Stirnansicht eines schwenkbaren Scherplättchens,
  • Fig. 4 eine Seitenansicht zu Fig. 3 und
  • Fig. 5 eine Draufsicht zu Fig. 4.
An embodiment of the invention is explained below with reference to the accompanying drawings, in which:
  • 1 shows a section through the cutting device parallel to the web guide,
  • 2 shows a cross section to FIG. 1,
  • 3 is an end view of a pivotable shear plate,
  • Fig. 4 is a side view of Fig. 3 and
  • 5 is a top view of FIG. 4.

In Figur 1 ist dargestellt, wie die Materialbahn 1 über die Leitwalze 6 der Schneidvorrichtung, bestehend aus einem oberen Scherplättchen 3 und einem unterem Scherplättchen 2, zugeführt wird. Dabei ist sowohl das obere als das untere Scherplättchen 3, 2 oder Schneidplättchen jeweils mit Befestigungsschrauben 8 bzw. 9 an einer Halterung 4 bzw. 5 befestigt. Jede Halterung 4 und 5 sitzt auf einer Welle 13 bzw. 14, die über die Maschinenbreite reicht und zwischen Seitenplatten gehalten ist.FIG. 1 shows how the material web 1 is fed via the guide roller 6 to the cutting device, consisting of an upper shear plate 3 and a lower shear plate 2. Both the upper and lower shear plates 3, 2 or cutting plates are each fastened to a holder 4 or 5 with fastening screws 8 or 9. Each bracket 4 and 5 sits on a shaft 13 and 14, which extends across the machine width and is held between side plates.

Mindestens eine Halterung 5 ist um die Achse der Welle 13 schwenkbar. Die Welle 13 tragt ein, Hülse 15. Die Halterung 5 sitzt auf der Hülse 15 zwischen Endflanschen 16 und 17, die in geeigneter Weise an der Hülse 15 angeordnet sind. Zwischen dem Endflansch 17 und der Halterung 5 stützt sich eine Druckfeder 10 ab. Der Endflansch 16 dient als Anschlag für die Halterung 5, damit dieselbe nicht von der Hülse 15 herabgleiten kann. Die Druckfeder 10 spannt die Halterung 5 axial so vor, daß die Schneiden aneinandergepreßt werden.At least one holder 5 is about the axis of the shaft 13 swiveling. The shaft 13 carries a sleeve 15. The holder 5 sits on the sleeve 15 between end flanges 16 and 17, which are arranged in a suitable manner on the sleeve 15. A compression spring 10 is supported between the end flange 17 and the holder 5. The end flange 16 serves as a stop for the holder 5 so that it cannot slide off the sleeve 15. The compression spring 10 biases the bracket 5 axially so that the cutting edges are pressed together.

Beide Halterungen sind gemeinsam axial, d.h. senkrecht zur Laufrichtung der zu schneidenden Materialbahn verschiebbar um die Bahnbreite variieren zu können. Vorzugsweise kann die axiale Verstellung der Scherplättchen mit Hilfe einer durch Gewindespindeln angetriebenen Mutter geschehen, wobei die Mutter sowie die Schneidvorrichtung verstellbare Anschläge aufweisen, die eine Mitnahme und Verschiebung der Scherplättchen ermöglichen. Dabei kann die Gewindespindel, die zum Verstellen benötigt wird, mit einer Zählvorrichtung versehen sein, die eine genaue Positionsangabe der Spindelmutter und damit der durch sie verstellten Schneidplättchen ermöglicht.Both brackets are axial together, i.e. Movable perpendicular to the direction of the material web to be cut in order to be able to vary the web width. The axial adjustment of the shear plates can preferably take place with the aid of a nut driven by threaded spindles, the nut and the cutting device having adjustable stops which enable the shear plates to be taken along and displaced. The threaded spindle, which is required for the adjustment, can be provided with a counting device which enables an exact position specification of the spindle nut and thus of the cutting plate which it adjusts.

Zum Schneiden einer flächigen Material bahn wird zunächst das untere Scherplättchen 2 an seiner Halterung 5 in Gegenuhrzeigerrichtung bezogen auf Fig. 1 ausgeschwenkt. Der Endflansch 16 verhindert ein Abgleiten der Halterung 5 von der Hülse 15. Die zu schneidende Materialbahn wird über die Walzen 6 und 7 eingezogen. Das ausgeschwenkte Scherplättchen wird wieder in den Bereich der Materialbahn eingeschwenkt, wobei die Schnittkante 11 und der Anschliff 12 des unteren Scherplättchens 2 die Bahn an- und einschneidet und so ein Eintauchen des Scherplättchens in die Materialbahn ermöglicht. Beim Zurücksenwenden wird die Halterung 5 entgegen der Wirkung der Druckfeder 10 zu- . rückgedrückt, damit die Schneiden der Scherplättchen ungehindert aneinander vorbeigleiten.To cut a flat material web, the lower shear plate 2 is first pivoted on its holder 5 in the counterclockwise direction with respect to FIG. 1. The end flange 16 prevents the holder 5 from sliding off the sleeve 15. The material web to be cut is drawn in via the rollers 6 and 7. The swung-out shear plate is pivoted back into the area of the material web, the cutting edge 11 and the bevel 12 of the lower shear plate 2 cutting and cutting the web and thus allowing the shear plate to be immersed in the material web. When turning back, the holder 5 is closed against the action of the compression spring 10. pressed back so that the cutting edges of the shaving plates slide past each other unhindered.

Das Schneiden der flächigen, bahnförmigen Materialien wie Gewebe, Papier, Folien, Film oder deren Kombinationen ist dadurch gekennzeichnet, daß die zu schneidende Bahn über zwei Walzen geführt wird, zwischen denen sich die Schneidvorrichtung befindet, deren oberes Scherplättchen mit seiner Schneide, die einen Keilwinkel von 70-90° aufweist, die zu schneidende Bahn berührt und deren unteres Scherplättchen in die zu schneidende Bahn eintaucht, so daß im Überschneidungsbereich der Schneiden das Material scherend durchgetrennt wird.The cutting of the flat, web-like materials such as fabric, paper, foils, film or their combinations is characterized in that the web to be cut is guided over two rollers, between which the cutting device is located, the upper shear plate with its cutting edge, which has a wedge angle has from 70-90 °, touches the web to be cut and dips its lower shear plate into the web to be cut, so that the material is sheared in the overlapping area of the cutting edges.

Die Schneidkante des unteren Scherplättchens ist exzentrisch zur Achse der Welle 13 angeordnet. Die Halterung 5 kann mit geringer Geschwindigkeit um die Achse der Welle 13 hin- und hergchend verschwenkt werden. Dadurch wird der Schneidpunkt mit dem oberen Scherplättchen 3 kontinuierlich verlagert, d.h. hin- und hergeschoben. Dieses vergleichmäßigt die Abnutzung der Schneidkanten.The cutting edge of the lower shear plate is arranged eccentrically to the axis of the shaft 13. The bracket 5 can with low Ge speed can be pivoted back and forth around the axis of the shaft 13. As a result, the cutting point with the upper shear plate 3 is continuously shifted, ie pushed back and forth. This smoothes out the wear of the cutting edges.

Die erfindungsgemäße Vorrichtung gestattet es, die Schneidplättchen nicht aus üblichen Materialien herzustellen, sondern auch Hartmetalle oder Keramik zu verwenden, wodurch ein weit geringerer Verschleiß möglich ist.The device according to the invention makes it possible not to produce the cutting tips from conventional materials, but also to use hard metals or ceramics, as a result of which much less wear is possible.
