Abstract
Description
Für das Schneiden von Folien verwendet man bisher Messer, die so beschaffen sind, wie in Blatt 1 Nr. 1, 2, 6 gezeichnet in Seitenansicht und Nr. 1, 2 daneben, Ansicht direkt von vorn (oder hinten). Wenn Schriften oder Embleme geschnitten werden sollen, wird in dem Computer, der dem Schneideplotter angeschlossen ist, neben den eigentlich zu schneidenden Linien auch die Drehung der Klinge in die entsprechende Schnittrichtung einprogrammiert. Die Schnittiefe wird durch Gewichte geregelt, die auf dem Messer aufgebracht werden können. Eine Variante sind Messer dieser Art, die drehbar kugelgelagert sind und sich selbständig ausrichten.Up to now, knives have been used for cutting foils, such as those shown in sheet 1 no. 1, 2, 6 in side view and no. 1, 2 next to it, view directly from the front (or rear). If fonts or emblems are to be cut, the rotation of the blade in the corresponding cutting direction is programmed in the computer connected to the cutting plotter in addition to the lines that are actually to be cut. The depth of cut is regulated by weights that can be applied to the knife. Knives of this type, which are rotatably mounted on ball bearings and align themselves independently, are a variant.
Ein Nachteil am Stand der Technik besteht im Aufbau der Klinge, weil es erforderlich ist, sie in die jeweilige Schnittrichtung zu drehen. Hieraus ergibt sich ein enor mer technischer Aufwand. Die drehbar kugelgelagerte Variante ist für genaues Arbeiten untauglich, weil der schneidende Teil (Blatt 1 Nr. 6) immer ein Stück von der Mittelachse entfernt ist und deshalb nie saubere Ecken geschnitten werden können. A disadvantage of the prior art is the construction of the blade because it is necessary to rotate it in the direction of the cut. This results in an enormous technical effort. The rotatable ball-bearing variant is unsuitable for precise work because the cutting part ( sheet 1 no. 6 ) is always a bit away from the central axis and therefore clean corners can never be cut.
Selbst wenn man diesen Fehler durch entsprechende Programmierung beheben könnte, würde er bei einer Veränderung des Maßstabs wieder in Erscheinung treten, weil der Abstand von der Mittelachse zum schneidenden Teil (Blatt 1 Nr. 6) gleich bliebe.Even if this error could be remedied by appropriate programming, it would reappear if the scale were changed, because the distance from the central axis to the cutting part ( sheet 1 No. 6 ) would remain the same.
Ein weiterer Nachteil besteht darin, daß die Schneide stumpf wird, was durch höheres Gewicht auf der Halterung der Klinge ausgeglichen werden kann, aber irgendwann wird das Material von der stumpfer werdenden Schneide zerrupft. Weil die Schneide der herkömmlichen Messer allmählich stumpf wird, ist die Qualität der Schnitte ständigen nachteiligen Änderungen unterworfen.Another disadvantage is that the cutting edge becomes dull, which is due to higher weight on the bracket the blade can be balanced, but eventually the material becomes blunt from the cutting edge torn apart. Because the cutting edge of conventional knives gradually becomes dull is the quality of the cuts subject to constant adverse changes.
Dieser Erfindung liegt die Aufgabe zugrunde, die oben erwähnten Nachteile zu beseitigen und dadurch das Schneiden zu vereinfachen und die Qualität zu ver bessern.This invention has for its object the above eliminate the disadvantages mentioned and thereby the Simplify cutting and improve quality improve.
Wie aus Blatt 1 Nr. 6 ersichtlich, wird die eigentliche Arbeit nur von der Spitze der Schneide erledigt. Weil auch die schärfste Schneide (bei starker Vergrößerung sichtbar) gerundet ist, wie in Blatt 1 Nr. 2 und 3 ersichtlich, und mit dieser Rundung schneidet, kann man diese Rundung, die die eigentliche Arbeit verrichtet, nach allen Seiten hin ausdehnen (gestrichelte Linie über der kleinen "3" in Blatt 1) und auf diese Weise in alle Richtungen schneiden, weil sich daraus ein Schneidewerk zeug ergibt, das als extrem dünner runder Stift das Material durchschneidet, ähnlich wie die Stahlsaiten eines Eierschneiders das gekochte Ei. As can be seen from Sheet 1 No. 6 , the actual work is only done from the tip of the cutting edge. Because even the sharpest cutting edge (visible at high magnification) is rounded, as can be seen in sheet 1, numbers 2 and 3 , and cuts with this rounding, this rounding, which does the actual work, can be extended to all sides (dashed line above the small "3" in sheet 1) and in this way cut in all directions, because this results in a cutting tool that cuts through the material as an extremely thin round pin, similar to the steel strings of an egg slicer, the boiled egg.
In diesem Fall muß aber die Schnittiefe genau definiert sein, um das Trägermaterial (Blatt 1 und 2 Nr. 5) nicht mit durchzuschneiden. Um eine gleichbleibende Schnittie fe zu gewährleisten, muß die Klinge (Blatt 2 Nr. 7) mit einem ringförmigen Abstandhalter (Blatt 2 Nr. 8) versehen sein, der auf der zu schneidenden Folie mit fährt, während die Schneide (Blatt 2 Nr. 6) genau dort, wo das Trägermaterial (Blatt 1 und 2 Nr. 5) anfängt, frei schwebt.In this case, however, the depth of cut must be precisely defined so that the backing material ( sheets 1 and 2 No. 5 ) is not cut through. In order to ensure a constant cutting depth, the blade ( Sheet 2 No. 7 ) must be provided with an annular spacer ( Sheet 2 No. 8 ) that moves with the film to be cut while the cutting edge ( Sheet 2 No. 6 ) hovers freely where the carrier material ( sheets 1 and 2 no. 5 ) begins.
Ein weiterer Vorteil des Schneidstiftes besteht da rin, daß er nicht stumpf wird, sondern mit zunehmender Abstützung immer schärfer.Another advantage of the cutting pin is there rin that it does not become dull, but with increasing Support ever sharper.
Weil für diese Methode extreme Anforderungen an das Material der Schneide (Blatt 2 Nr. 6) gestellt werden (hohe Standfestigkeit bei einem Durchmesser von nur wenigen tausendstel Millimetern), läßt sich dieses Ver fahren vorerst nur für sehr dünne Materialien verwen den, wie z. B. PVC-Folie, die normalerweise nur 0,070 -0,100 mm dick ist (Schnittdicke: Bild 2 Nr. 9).Because for this method extreme demands are made on the material of the cutting edge ( Sheet 2 No. 6 ) (high stability with a diameter of only a few thousandths of a millimeter), this method can initially only be used for very thin materials, such as. B. PVC film, which is usually only 0.070-0.100 mm thick (section thickness: Fig. 2 No. 9 ).
Aus welchem Material die Stiftschneide deshalb herge stellt wird, hängt von den gestellten Aufgaben ab. Es kann auch vorgesehen werden, die Schneide aufzuheizen, um das Gleiten durch schmelzbares Material zu erleichtern. Die Ansicht der Stiftschneide in Blatt 2 ist von allen Seiten gleich.Which material the pen cutting edge is therefore made of depends on the tasks. It can also be provided that the cutting edge is heated in order to facilitate sliding through fusible material. The view of the cutting edge in sheet 2 is the same from all sides.
