Description

Gegenstand der Erfindung ist eine Schneidvorrichtung zum Längsschneiden von flächigen, bahnförmigen Materialien, insbesondere Folien, wobei ein an einer Halterung sitzendes Scherplättchen oberhalb und ein an einer Halterung sitzendes Scherplättchen unterhalb des zu schneidenden Materials angeordnet ist und wobei die parallel zueinander ausgerichteten Schneiden der Scherplättchen einander im Schneidbereich unter Vorspannung berühren.The invention relates to a cutting device for longitudinally cutting flat, sheet-like materials, in particular foils, wherein a shear plate seated on a holder is arranged above and a shear plate seated on a holder is arranged below the material to be cut, and wherein the cutting edges of the shear plate aligned parallel to one another are arranged in one another Touch the cutting area under pre-tension.

Eine Schneidvorrichtung der genannten Art ist aus der DE-A-2 633 340 bekannt. Diese Schneidevorrichtung arbeitet mit Kreismessern. Hier sind besondere Maßnahmen zur Einstellung der axialen Anlagekraft vorgesehen. Trotzdem tritt ein großer Verschleiß der Schnittkanten der Schneidwerkzeuge durch die gegenseitige Bewegung dieser Maschinenteile und unter dem Einfluß des Schnittdruckes auf.A cutting device of the type mentioned is known from DE-A-2 633 340. This cutting device works with circular knives. Special measures for adjusting the axial contact force are provided here. Nevertheless, there is a great deal of 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.

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 gelößt, daß mindestens eine Halterung schwenkbar auf einer Welle angeordnet ist und daß die Schneide des schwenkbar angeordneten Scherplättchens exzentrisch zur Achse der Welle ausgerichtet ist.This object is achieved according to the invention in that at least one holder is arranged pivotably on a shaft and that the cutting edge of the pivotably arranged shear plate is aligned eccentrically to the axis of the shaft.

Die Erfindung unterscheidet insofern vom Stand der Technik, als ein Scherenschnitt im wesentlichen feststehenden Scherplättchen erzeugt wird. Ein Gleiten der Scherplättchen aneinander erfolgt nicht, so daß die Abnutzung der Scherplättchen weitgehend herabgesetzt wird. Da die Scherplättchen feststehen, ergibt sich eine exakte und gerade Schnittführung. Die exzentrische Anordnung des schwenkbar angeordneten Scherplättchens ermöglicht eine Verlagerung des Schneidpunktes und eine Verringerung und Vergleichmäßigung der Abnutzung der Scherplättchen. Die Schwenkbarkeit der Halterung des einen Scherplättchens erleichtert das Einführen der Materialbahn.The invention differs from the prior art in that a scissor cut produces essentially fixed shear plates. The shear plates do not slide against one another, so that the wear of the shear plates is largely reduced. Since the shear plates are fixed, an exact and straight cut results. The eccentric arrangement of the pivotably arranged shear plates enables the cutting point to be shifted and the wear of the shear plates to be reduced and evened out. The pivoting of the holder of the one shear plate facilitates the insertion of the material web.

In Weiterbildung der Erfindung, wird die Schnittwirkung dadurch verbessert, daß die Schneide des schwenkbar angeordneten Scherplättchen einen Keilwinkel von 70 - 90° aufweist.In a further development of the invention, the cutting effect is improved in that the cutting edge of the pivotably arranged shear plate has a wedge angle of 70-90 °.

Damit sich das schwenkbare Scherplättchen beim Einschwenken sicher in die Materialbahn einschneidet, ist vorgesehen, daß wenigstens das schwenkbar angeordnete Scherplättchen an einer Schnittkante einen Anschliff aufweist.So that the pivotable shear plate cuts securely into the material web when it is pivoted in, it is provided that at least the pivotably arranged shear plate has a bevel on one cutting edge.

Eine Verschiebung des Schneidpunktes über einen großen Bereich des feststehenden Scherplättchens wird dadurch sichergestellt, daß die Halterung auf der Welle mit geringer Drehgeschwindigkeit hin- und hergehend antreibbar ist.A displacement of the cutting point over a large area of the fixed shear plate is ensured in that the holder can be driven back and forth on the shaft at a low rotational speed.

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 schwenkbar 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 trägt ein Hülse 15. Die Halterung 5 sitzt auf der Hülse 15 zwischen Endflanschen 16 und 17, die in geeigneter Weise en 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 bracket 5 is pivotable about the axis of the shaft 13. 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 en 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 the latter cannot slide down from 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, d. H. Slidable 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 Materialbahn 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 12 und der Anschliff 11 des unteren Scherplättchens 2 die Bahn an- und einschneidet und so ein Eintauchen des Scherplättchens in die Materialbahn ermöglicht. Beim Zurückschwenken wird die Halterung 5 entgegen der Wirkung der Druckfeder 10 zurückgedrückt, damit die Schneiden der Scherplättchen ungehindert aneinander vorbeigleiten.To cut a flat web of material, the lower shear plate 2 is first swung out 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 12 and the bevel 11 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 pivoting back, the holder 5 is pushed back against the action of the compression spring 10 so that the cutting edges of the shear 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 6, 7 geführt wird, zwischen denen sich die Schneidvorrichtung befindet, deren oberes Scherplättchen 3 mit seiner Schneide, die einen Keilwinkel von 70 - 90° aufweist, die zu schneidende Bahn 1 berührt und deren unteres Scherplättchen 2 in die zu schneidende Bahn 1 eintaucht, so daß im Überschneidungsbereich der Schneiden das Material scherend durchgetrennt wird.The cutting of flat, sheet-like materials such as tissue, paper, foils, film or their combinations is characterized in that the web to be cut is guided over two rollers 6, 7, between which the cutting device is located, the upper shear plate 3 with its cutting edge, which has a wedge angle of 70-90 °, the web to be cut 1 touches and its lower shear plate 2 dips into the web 1 to be cut, so that the material is sheared in the overlapping area of the cutting.

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 hergehend 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 holder 5 can be pivoted back and forth at a low speed around the axis of the shaft 13. As a result, the cutting point with the upper shear plate 3 is continuously shifted. d. H. 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.
