Description
Die Erfindung betrifft ein Rundmesser nach dem Oberbegriff des Anspruchs 1.The invention relates to a circular blade according to the preamble of claim 1.
Messer zum Ausführen von Perforierungen sind an sich bekannt. Aus der
Aus der
Die Aufgabe der Erfindung ist es, ein Rundmesser zu schaffen, mit dem unterschiedliche Schnitttiefen möglich sind.The object of the invention is to provide a circular blade, with the different depths of cut are possible.
Die Aufgabe wird bei einem Rundmesser durch die Merkmale des Anspruchs 1 gelöst. Günstige Ausgestaltungen und Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und der Zeichnung.The problem is solved in a rotary blade by the features of claim 1. Favorable embodiments and advantages of the invention will become apparent from the other claims, the description and the drawings.
Es wird ein Rundmesser zum Ausführen einer Schnittbahn vorgeschlagen, mit einem Messerkörper, dessen Außenumfang einen Zahnkranz aufweist, bei dem alternierend Zähne und Zahnzwischenräume mit Zahngründen aufeinander folgen. Der Messerkörper ist aus wenigstens zwei Teilmessern gebildet, wobei die Trennung der wenigstens zwei Teilmesser quer zur Drehachse des Messerkörpers vorgesehen ist. Ein erstes der Teilmesser weist einen Zahnkranz auf, bei dem die Zähne als Schneidkanten und die Zahngründe nicht als Schneidkanten ausgebildet sind, und ein zweites der Teilmesser weist einen Zahnkranz auf, dessen Zähne und Zahngründe als Schneidkanten ausgebildet sind.It proposes a circular blade for performing a cutting path, with a knife body whose outer periphery has a ring gear, in which alternately teeth and interdental spaces follow one another with tooth reasons. The knife body is formed from at least two partial blades, wherein the separation of the at least two partial blades is provided transversely to the axis of rotation of the knife body. A first one of the dividing knives has a ring gear in which the teeth are not formed as cutting edges and the tooth bottoms are formed as cutting edges, and a second one of the dividing knives has one Toothed ring, whose teeth and tooth roots are formed as cutting edges.
Das Rundmesser rollt entlang der Schnittbahn auf der Oberfläche des zu schneidenden Guts, z.B. Wellpappe, ab. Vorteilhaft können mit dem Rundmesser Schnitte in zwei Schnitttiefen durchgeführt werden. Insbesondere ist es möglich, eine Schnittbahn in Wellpappe auf beiden Seiten zu generieren, obwohl das Rundmesser nur auf einer Seite angesetzt ist. Dabei wird die Außenhaut der Wellpappe auf der Seite, an der das Rundmesser angreift, ganz durchschnitten und die gegenüberliegende Seite nur von den Messerzähnen durchstoßen. Wirkt das Rundmesser mit einem Abstandshalter zusammen, kann die Eindringtiefe des Rundmessers genau eingestellt werden.The circular knife rolls along the cutting path on the surface of the material to be cut, e.g. Corrugated board, from. Advantageously, cuts can be made in two cutting depths with the circular blade. In particular, it is possible to generate a cutting path in corrugated cardboard on both sides, although the circular blade is attached only on one side. The outer skin of the corrugated cardboard on the side on which the circular blade attacks, completely cut through and pierce the opposite side only of the knife teeth. If the rotary knife interacts with a spacer, the penetration depth of the circular blade can be precisely adjusted.
Gemäß einer günstigen Ausgestaltung können die wenigstens zwei Teilmesser Zähne und Zahnzwischenräume aufweisen und um die Drehachse des Messerkörpers gegeneinander verdrehbar sein. Werden die wenigstens zwei Teilmesser gegeneinander verdreht, können unterschiedliche Abstände der Schneidkanten der Teilmesser und damit unterschiedliche Schnitttiefen des Messers eingestellt werden.According to a favorable embodiment, the at least two partial blades may have teeth and interdental spaces and be rotatable relative to each other about the axis of rotation of the blade body. If the at least two dividing knives are rotated relative to one another, different distances between the cutting edges of the dividing knives and thus different cutting depths of the knife can be set.
Gemäß einer günstigen Ausgestaltung können die Schneidkanten der Zähne so tangential zum Umfang oder entlang des Umfangs gekrümmt ausgebildet sein. Damit kann ein Schnitt ausgeführt werden, der im Wesentlichen senkrecht zu einer benachbart zum Rundmesser befindlichen Oberfläche der Wellpappe verläuft. Ein ziehender Schnitt, bei dem eine Schneidkante in Schneidrichtung durch die Wellpappe gezogen wird, was zu Rissen und Ausbrüchen und dergleichen führen kann, kann vermieden werden.According to a favorable embodiment, the cutting edges of the teeth may be formed so tangential to the circumference or along the circumference curved. Thus, a cut can be made which is substantially perpendicular to a surface of the corrugated cardboard adjacent to the circular blade. A pulling cut, in which a cutting edge is pulled through the corrugated cardboard in the cutting direction, which can lead to cracks and breakouts and the like, can be avoided.
Gemäß einer günstigen Ausgestaltung kann der Zahnkranz in radialer Richtung nach außen zumindest an einer Flachseite des Messerkörpers abgeschrägt sein. Insbesondere kann der Zahnkranz an beiden Flachseiten des Messerkörpers abgeschrägt sein. Damit ergibt sich eine definierte, scharfe Schneidkante an den Zähnen und/oder am Zahngrund.According to a favorable embodiment of the sprocket may be bevelled in the radial direction to the outside at least on a flat side of the knife body. In particular, the sprocket may be chamfered on both flat sides of the knife body. This results in a defined, sharp cutting edge on the teeth and / or on the tooth base.
Gemäß einer günstigen Ausgestaltung kann das erste der Teilmesser einen größeren Umfang aufweisen als das zweite der Teilmesser. Damit ist eine definierte Messergröße vorgegeben. Eine oder mehrere Schneidkanten mit verschiedenen Schnitttiefen können in den Zahnzwischenräumen des ersten Teilmessers bereitgestellt werden, dessen Zahngründe nicht als Schneidkanten ausgebildet sind.According to a favorable embodiment, the first of the dividing blades may have a larger circumference than the second of the dividing blades. This defines a defined blade size. One or more cutting edges with different cutting depths may be in the interdental spaces of the first Partial knife be provided whose tooth surfaces are not formed as cutting edges.
Gemäß einer günstigen Ausgestaltung können die Zähne des zweiten der Teilmesser mindestens so breit sein, dass sie die Zahnzwischenräume des ersten der Teilmesser ausfüllen. Damit sind definierte Abmessungen der Perforation sowie eine definierte Positionierung der Teilmesser zueinander erreichbar.According to a favorable embodiment, the teeth of the second of the dividing blades may be at least as wide that they fill the interdental spaces of the first of the dividing blades. Thus, defined dimensions of the perforation and a defined positioning of the part diameter are accessible to each other.
Gemäß einer günstigen Ausgestaltung können die Zahngründe des zweiten der Teilmesser mindestens so breit sein, dass sie die Zahnzwischenräume des ersten der Teilmesser ausfüllen. Damit sind definierte Abmessungen der Perforation sowie eine definierte Positionierung der Teilmesser zueinander erreichbar.According to a favorable embodiment, the tooth bottoms of the second of the dividing blades may be at least as wide that they fill the interdental spaces of the first of the dividing blades. Thus, defined dimensions of the perforation and a defined positioning of the part diameter are accessible to each other.
Gemäß einer günstigen Ausgestaltung können die Zahnkörper der Teilmesser eine oder mehrere Markierungsmittel aufweisen, um eine erste und/oder zweite Stellung der Teilmesser zueinander definiert anzuzeigen. Die Teilmesser können in definierter Weise für verschiedene Schnitttiefen zueinander positioniert werden. Dies kann vorteilhaft durch manuelle Positionierung durch optische Kontrolle anhand der einen oder mehreren Markierungsmitteln erfolgen.According to a favorable embodiment, the toothed bodies of the dividing knives can have one or more marking means in order to display a first and / or second position of the dividing knives defined relative to one another. The dividers can be positioned in a defined manner for different cutting depths to each other. This can be done advantageously by manual positioning by optical control using the one or more marking agents.
Das erfindungsgemäße Rundmesser kann in Schneid- oder Perforiermaschinen verwendet werden, oder in handgehaltenen Werkzeugen.The circular blade according to the invention can be used in cutting or perforating machines, or in hand-held tools.

Das erste Teilmesser 40 hat einen scheibenförmigen Teilmesserkörper mit einer zentralen Öffnung 28, wobei am Außenumfang des Teilmesserkörpers ein Zahnkranz 48 vorgesehen ist, bei dem alternierend Zähne 42 und Zahnzwischenräume 44 gleichmäßig beabstandet aufeinander folgen. Die Zähne 42 sind in der Draufsicht im Wesentlichen als rechteckförmige Keile ausgebildet. In der zentralen Öffnung 28 ist ein Zapfen als Markierungsmittel 62 vorgesehen, mit der eine rotatorische Position des Teilmessers 40, bezogen auf seine Drehachse, bestimmbar ist. Das Markierungsmittel kann in geeigneter Weise auch anders gestaltet sein, z.B. als Nut, Kerbe oder dergleichen.The first dividing
Das zweite Teilmesser 50 hat einen scheibenförmigen Teilmesserkörper mit einer zentralen Öffnung 28, wobei am Außenumfang des Teilmesserkörpers ein Zahnkranz 58 vorgesehen ist, bei dem alternierend Zähne 52 und Zahnzwischenräume 54 gleichmäßig beabstandet aufeinander folgen. Die Zähne 52 sind in der Draufsicht im Wesentlichen als rechteckförmige Keile ausgebildet. In der zentralen Öffnung 28 sind zwei Zapfen als Markierungsmittel 64, 66 vorgesehen, mit der eine rotatorische Position des Teilmessers 50, bezogen auf seine Drehachse, bestimmbar ist.The
Jedes der Teilmesser 40, 50 hat eine ebene Rückseite und eine Vorderseite, die zumindest am Zahnkranz 48, 58 in radialer Richtung nach außen abgeschrägt ist. Werden die beiden Teilmesser 40, 50 mit ihren Rückseiten aneinander gelegt, zeigt das resultierende Rundmesser 10 in Seitenansicht eine spitze Mittelkante 60 (
Die Schnitttiefe des Rundmessers 10 lässt sich verändern, indem die Teilmesser 40, 50 gegeneinander verdreht werden, z.B. um eine Zahnbreite gegeneinander verdreht werden.The cutting depth of the
Das erste Teilmesser 40 weist Schneidkanten an den freien Enden der Zähne 42 auf, während die Zahngründe 46 keine Schneidkanten aufweisen. Das zweite Messer 50 weist Schneidkanten sowohl an den freien Enden der Zähne 52 als auch an den Zahngründen 56 auf. Das erste Teilmesser 40 weist einen größeren Umfang auf als das zweite Teilmesser 50.The
Die Schneidkanten der Zähne 42, 52 können tangential zum Umfang oder entlang des Umfangs des Teilmessers 40 gekrümmt verlaufen. Damit wird ein ziehender Schnitt vermieden, der zu Materialausbrüchen oder Rissen führen kann. Die Zähne 42, 52 können z.B. eine trapezförmige Grundfläche aufweisen.The cutting edges of the
Die zentrale Öffnung 28 dient zur Befestigung des Rundmessers 10 an einem Werkzeughalter einer Maschine oder eines handgeführten Werkzeugs (nicht dargestellt), mit dem das Rundmesser 10 entlang eines zu bearbeitenden Guts, z.B. Wellpappe, geführt wird. Insbesondere ist das Rundmesser 10 drehend antreibbar, so dass es entlang der Oberfläche des zu bearbeitenden Guts abrollt und dabei einen Perforationsschnitt generiert. Dabei durchstoßen die Schneidkanten der Zähne 42, 52 und der Zahngründe 46, 56 die Außenhaut vollständig und einen außenhautnahen Bereich der gewellten Zwischenlage, welche Außenhaut und Innenhaut beabstandet, während die Innenhaut nur von den Schneidkanten der Zähne 42, 52 durchstoßen wird.The
Die Breiten der Zähne 42, 52 und der Zahnzwischenräume 44, 54 sind in diesem Beispiel ungefähr gleich ausgebildet. Bei Bedarf können diese auch, je nach erwünschtem Schnittbild und/oder zu schneidendem Material, unterschiedliche Breite aufweisen.The widths of the
Für eine geringe Schnitttiefe werden die beiden Teilmesser 40, 50 so zueinander verdreht, dass die Zähne 52 des zweiten Teilmessers 50 zwischen den Zähnen 42 des ersten Teilmessers 40 angeordnet sind. Für eine große Schnitttiefe werden die beiden Teilmesser 40, 50 um eine Zahnbreite weitergedreht, so dass die Zahngründe 56 des zweiten Teilmessers 50 zwischen den Zähnen 42 des ersten Teilmessers 40 angeordnet sind. Die rotatorische Stellung der beiden Teilmesser 40, 50 zueinander kann auch an der Stellung der Markierungsmittel 62, 64, 66 zueinander abgelesen werden.For a small depth of cut, the two
