Die Erfindung betrifft eine Schneidvorrichtung zum Schneiden von gestapeltem blattförmigen Gut, insbesondere Papier, Karton und dergleichen mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The The invention relates to a cutting device for cutting stacked leaf-shaped good, in particular paper, cardboard and the like with those in the preamble of claim 1 specified characteristics.
Vorrichtungen dieser Art sind allgemein bekannt und werden beispielsweise in Druckereien eingesetzt, um die aus der Druckmaschine kommenden Papierstapel auf Zwischen- oder Endmaß zuzuschneiden. Dabei werden an die Maßgenauigkeit der einzelnen Blätter erhebliche Anforderungen gestellt.devices This type are well known and are used for example in printing companies used to the coming out of the printing press paper stack to cut to intermediate or final dimensions. Here are the dimensional accuracy the individual leaves considerable demands.
Die Aufgabe der Erfindung ist es, eine Schneidvorrichtung zu schaffen, mit welcher das Schneidergebnis beim Schneiden von gestapeltem blattförmigem Gut weiter verbessert wird.The The object of the invention is to provide a cutting device, with which the cutting result when cutting stacked sheet material is further improved.
Diese Aufgabe wird erfindungsgemäß durch eine Schneidvorrichtung mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und der Zeichnung.These The object is achieved by a Cutting device solved with the features specified in claim 1. advantageous Further developments of the invention will become apparent from the dependent claims, the following description and the drawing.
Die erfindungsgemäße Schneidvorrichtung dient zum Schneiden von gestapeltem blattförmigem Schneidgut und insbesondere zum Schneiden von Papier, Karton und dergleichen. Sie umfasst ein Traggestell sowie eine Fixiereinrichtung zum Fixieren des zu schneidenden Guts in dem Traggestell. Des Weiteren ist in dem Traggestell ein Schneidmesser mit einer Schneidkante bewegbar geführt, welches erfindungsgemäß zu beiden Seiten der Schneidkante abgeschrägt ausgebildet ist.The Cutting device according to the invention is used for cutting stacked sheet material and in particular for cutting paper, cardboard and the like. It includes a support frame and a fixing device for fixing the material to be cut in the support frame. Furthermore, in the support frame with a cutting knife a cutting edge movably guided, which according to the invention to both Sides of the cutting edge chamfered is trained.
In einer bei Schneidvorrichtungen dieser Art an sich bekannten Weise ist ein Traggestell vorgesehen, in dem ein oder mehrere Stapel blattförmigen Schneidguts mittels einer Fixiervorrichtung in dem Traggestell in der Schneidposition fixiert werden und von einem in unmittelbarer Nähe der Fixiervorrichtung bewegten Schneidmesser in der gewünschten Weise zugeschnitten werden. Hierzu ist das Schneidmesser in dem Traggestell zumindest auf- und abwärts bewegbar geführt, typischerweise jedoch zur Ausführung eines Wiegeschnittes.In a known in cutting devices of this kind a support frame is provided in which one or more stack of sheet-like material to be cut by means of a fixing device in the support frame in the cutting position be fixed and moved from one in the immediate vicinity of the fixing Cutting knife in the desired manner be tailored. For this purpose, the cutting blade in the support frame at least up and down movably guided, but typically for execution a weighing cut.
Während es bislang üblich war, in Vorrichtungen dieser Art Schneidmesser zu verwenden, bei denen an der Schneidkante eine durchgehend plane Rückseitenfläche des Schneidmessers und eine dazu schräg gerichtete Vorderseitenfläche des Schneidmessers zusammenlaufen, sieht die Erfindung vor, nicht nur eine von der Schneidkante ausgehende Fläche schräg auszubilden sondern die beiden von der Schneidkante ausgehenden Flächen bezüglich einer Bezugsebene, in welcher sich die Schneidkante bei der Schneidbewegung bewegt gegensinnig abgeschrägt auszubilden. Hierzu ist vorgesehen, die der Fixiervorrichtung abgewandte Vorderseite des Schneidmessers in üblicher Weise mit einem zu der Bezugsebene schrägen Anschliff zu versehen, gleichzeitig aber auch die der Fixiervorrichtung zugewandte Rückseite des Schneidmessers in dem von der Schneidkante ausgehenden Bereich in geringem Masse schräg zu der Bezugsebene anzuschleifen. Durch diese Ausgestaltung des Schneidmessers kann die Schnittqualität beim Schneiden von gestapeltem blattförmigem Gut weiter verbessert werden.While it so far common was to use cutting devices in devices of this type which at the cutting edge a continuous plane rear side surface of the Cutting knife and an obliquely directed front surface of the cutting blade converge, the invention provides, not just one of the Cutting edge outgoing surface aslant form but the two emanating from the cutting edge surfaces in terms of a reference plane in which the cutting edge in the cutting movement moved in opposite directions bevelled train. For this purpose, it is provided that faces away from the fixing device Front of the cutting blade in the usual way with one to oblique the reference plane Beveled to provide at the same time as the fixing device facing back of the cutting blade in the area extending from the cutting edge Slightly oblique to grind to the reference plane. By this configuration of the Cutting knife can improve the cut quality when cutting from stacked in sheet Good to be further improved.
Es hat sich gezeigt, dass besonders gute Schnittergebnisse dann erzielt werden, wenn, wie bevorzugt vorgesehen, eine der Fixiereinrichtung zugewandte von der Schneidkante ausgehende Fläche an der Rückseite des Schneidmessers mit der Bezugsebene einen Winkel einschließt, der in einem Bereich von 0,03° bis 0,7° liegt, wobei vorteilhafterweise die der Fixiereinrichtung zugewandte von der Schneidkante ausgehende Schrägfläche des Schneidmessers eine auf die Bezugsebene projizierte Höhe von mindestens 0,5 mm und höchstens 40 mm aufweist. Auf diese Weise ist die der Fixiereinrichtung zugewandte Rückseite des Schneidmessers ausgehend von der Schneidkante nur in einem vergleichsweise kleinen Bereich und in sehr kleinem Winkel relativ zu der Bezugsebene angeschliffen, was aber dazu führt, dass die Maßhaltigkeit der einzelnen Blätter eines Blattstapels erhöht wird.It has been shown to achieve particularly good cutting results be, if, as preferably provided, one of the fixing device facing surface at the back of the cutting edge of the cutting blade with the reference plane forms an angle, the in a range of 0.03 ° to 0.7 °, wherein advantageously the fixing device facing from the cutting edge outgoing inclined surface of the cutting blade a height of at least 0.5 mm and projected onto the reference plane at the most 40 mm. In this way, the fixing device facing back of the cutting blade starting from the cutting edge only in a comparatively small area and at a very small angle relative to the reference plane sanded, but that leads to that dimensional accuracy the individual leaves of a sheet pile increased becomes.
Des Weiteren sieht eine weitere vorteilhafte Ausgestaltung der Erfindung vor, dass die von der Fixiereinrichtung abgewandte von der Schneidkante ausgehende Schrägfläche an der Vorderseite des Schneidmessers mit der Bezugsebene einen Winkel einschließt, welcher in einem Bereich von 10° bis 35° liegt.Of Further provides a further advantageous embodiment of the invention that the remote from the fixing device emanating from the cutting edge Bevel at the Front of the cutting blade with the reference plane forms an angle, which in a range of 10 ° to 35 °.
Vorzugsweise ist die Schneidvorrichtung zur Ausführung eines Wiegeschnitts ausgebildet. Darunter ist zu verstehen, dass das Schneidmesser in dem Traggestell derart geführt ist, dass es sich bei der Schneidbewegung gleichzeitig nach unten und zur Seite bewegt, wobei es zusätzlich noch eine Schwenkbewegung ausführt, so dass die Schneidkante des Messers erst zum Ende eines Arbeitshubs parallel zur Auflage des Blattstapels angeordnet ist.Preferably the cutting device is designed for carrying out a weighing cut. By this is meant that the cutting blade in the support frame so led is that it is at the same time cutting down the cutting motion and moved to the side, in addition there is still a pivoting movement executing, so that the cutting edge of the knife does not parallel until the end of a working stroke is arranged to support the sheet stack.
Vorteilhaft weist die Schneidvorrichtung einen Tisch zur Aufnahme des gestapelten Guts auf. Dieser Tisch kann sowohl Teil des Traggestells bilden, als auch separat ausgebildet sein. Zweckmäßigerweise weist dabei die Fixiervorrichtung einen Pressbalken zum Fixieren des gestapelten Guts auf dem Tisch auf. Der Pressbalken ist so angeordnet, dass er das gestapelte Gut in Schneidrichtung über seine gesamte Länge in unmittelbarer Nähe der vorgesehenen Schnittlinie fixiert.Advantageously, the cutting device on a table for receiving the stacked goods. This table can both form part of the support frame, as well as be formed separately. Conveniently, the fixing device has a Press beam for fixing the stacked goods on the table. The press beam is arranged so that it fixes the stacked good in the cutting direction over its entire length in the immediate vicinity of the intended cutting line.
