Description
Kreis- oder bogenförmig gestaltetes Messer für Maschinen zum Schneiden von mit fester Rinde, Haut o.dgl. umhülltem Schneidgut Die Erfindung betrifft ein kreis- oder bogenförmig gestaltetes, für Maschinen zum Schneiden von mit fester Rinde, Haut. o.dgl. umhulltem Schneidgut bestimmtes Messer, dessen Schneide aus einer Anzahl Einzelschneiden mit allmählich ansteigender Schneidbrust und steil abfallender Rtickenkante besteht. Circular or arched knife for cutting machines of with firm bark, skin or the like. wrapped material to be cut The invention relates to a Circular or arched, for machines for cutting with solid Bark, skin. or the like. enveloped material to be cut a certain knife, the cutting edge of which a number of individual cutting edges with a gradually rising cutting face and steep sloping back edge exists.
Derartige Messer sind .nekaant. Die bekannten Besser schneiden das Schneidgut für den Falls daß des Schneidgut eine feste Rinde oder Haut aufweist, nur unter relativ großem Anpreßdruck. Dies hat zur Folge, daß das Schneidgut gequetscht wird. Die Spitzen der Einzelschneiden des Messers unterliegen dabei einer starken Belastung und nutzen sich dadurch vorzeitig ab, wodurch die Schneidleistung des Messers herabgesetzt wird. Bs sind auch bereits Messer bekannt, deren Einzelschneiden ganz oder teilweise eine aus dicht nebeneinanderliegenden Zonen gebildete Feinverzahnung auf'reisen. Durch die Feinverzahnung wird zwar die Schneidleistung des Messers insofern erhöht, als die Umhüllung des Schneidgutes unter geringerem Anpreßdruck geschnitten wird. Mit derartigen Messern lßt sich jedoch infolge der Feinverzahnung kein glatter Schnitt erzielen. Es besteht zudem die Gefahr, daß sich die Lücken zwischen den feinen Zähnen, nachdem die feinen Zähne die Umhüllung des Schneidgutes durchschnitten haben, beim Eindringen des Messers in den gegenüber der Umhüllung weicheren Teil des Schneidgutes zusetzen.Such knives are .nekaant. The known better cut that Material to be cut in the event that the material to be cut has a firm bark or skin, only under relatively high pressure. As a result, the material to be cut is squashed will. The tips of the individual cutting edges of the knife are subject to a strong one Load and wear out prematurely, reducing the cutting performance of the Knife is lowered. Knives are also already known whose individual cutting edges completely or partially a fine toothing formed from closely spaced zones to travel. The fine toothing increases the cutting performance of the knife increased than the wrapping of the food to be cut under less Contact pressure is cut. Such knives, however, can be used due to the fine toothing do not achieve a smooth cut. There is also the risk that the gaps between the fine teeth, after the fine teeth are wrapped around the food have cut through when the knife penetrates into the opposite of the sheath add the softer part of the food.
Bs ist Aufgabe der Erfindung, diese den Messers der eingangs beschriebenen Gattung anhaftenden Nachteile zu beseitigen. Die Lösung der Aufgabe besteht darin, daß zwischen den Einzel schneiden des Messers mindestens ein spitz gestalteter Zahn angeordnet ist.Bs is the object of the invention, this the knife of the initially described Eliminate disadvantages inherent in the genus. The solution to the task is to that between the individual cutting of the knife at least one pointed tooth is arranged.
Mit Hilfe der spitz gestalteten Zähne vird, bevor die Einzelschneiden einen Schnitt vollführen, zuvor die harte Umhüllung des Schneidgutes aufgerissen. Der zum Schneiden des Schneidgutes erforderliche, von dem Hesser auf das Schneidgut ausgeübte Anpreßdruck ist dadurch auf ein solches Maß reduziert, daß das Schneidgut nicht mehr vie bisher gequetscht wird. Es wird dabei durch die spitz gestalteten Zähne der durch die Einzelschneiden erzielte Schnitt mit Bezug auf seine Glätte nicht beeinträchtigt, da die spitz gestalteten Zähne in die in dem Schneidgut durch die Einzelschneiden erzeugten Einschnitte einlaufen und dadurch das Schneidgut nicht angreifen. Aus dem gleichen Grunde können sich die Lücken zwischen den spitz gestalteten Zähnen und den Rückenkanten der Einzelschneiden nicht zusetzen.With the help of the pointed teeth, before the individual cutting make a cut, first tearing open the hard covering of the food to be cut. The one required to cut the material to be cut, from the cutter to the material to be cut exerted contact pressure is reduced to such an extent that the material to be cut is no longer squeezed like before. It is thereby designed by the pointed Teeth the cut achieved by the individual cutting edges with regard to its smoothness not impaired, as the pointed teeth in the cut through the incisions produced by the individual cutting edges run in, and thus the material to be cut does not attack. From the same reason, the gaps between Do not clog the pointed teeth and the back edges of the individual cutting edges.
Anstelle eines zeitz gestalteten Zahnes zwischen den Einzelschneiden können auch mehrere spitz gestaltete Zähne angeordnet werden. Die spitz gestalteten Zähne brauchen auch nicht zwischen sämtlichen Einzelschneiden angeordnet zu sein, ohne daß dadurch die Schneidleistung beeinträchtigt ist. Es besteht vielmehr auch die Möglichkeit, einzelne Einzelschneiden unmittelbar aneinanderzureihen, ohne daß ein spitz gestalteter Zahn zwischen ihnen angeordnet ist.Instead of a Zeitz designed tooth between the individual cutting edges several pointed teeth can also be arranged. The pointed ones Teeth do not need to be arranged between all the individual cutting edges, without affecting the cutting performance. Rather, it also exists the possibility of stringing individual individual cutting edges directly next to one another without a pointed tooth is arranged between them.
In der Zeichnung ist die ErEindung in einer beispielsweisen Ausführung an einem Kreismesser veranschaulicht. Es zeigt; Fig. 1 das teilweise gezeichnete Kreismesser in Ansicht und Fig. 2 einen Teil der Schneide des Kreismessers in vergrößertem Maßstab in Ansicht.In the drawing, the invention is in an exemplary embodiment illustrated on a circular knife. It shows; Fig. 1 is the partially drawn Circular knife in a view and FIG. 2 a part of the cutting edge of the circular knife in an enlarged view Scale in view.
Mit 1 ist das Kreismesser bezeichnet. Die Schneide des greismessers 1 setzt sich aus Einzelschneiden 2 zusammen, deren Schneidbrust 3 allmählich ansteigt und deren Rückenkante 4 steil abfällt Zwischen den Einzelschneiden 2 sind spitz gestaltete Zähne 5 angeordnet. Diese liegen mit ihren Spitzen auf einem gemeinsamen Kreisbogen.With 1 the circular knife is referred to. The cutting edge of the knife 1 is composed of individual cutting edges 2, the cutting face 3 of which gradually increases and the back edge 4 of which slopes steeply. Between the individual cutting edges 2 are pointed shaped teeth 5 arranged. These are with their tips on a common Circular arc.
