Description
Vorrichtung zum Abschneiden oder Perforieren von Platten oder Folien aus zähen, plastischen Werkstoffen Die Neuerung bezieht sich auf eine Vorrichtung zum Abschneiden oder Perforieren von Platten oder Folien aus zähèn, plstischen Werkstoffen, insbesondere von Kunststoffen wie z. B. Polyäthylen.Device for cutting or perforating sheets or foils made of tough, plastic materials The innovation relates to a device for cutting or perforating sheets or foils made of tough, plastic materials, especially of plastics such. B. polyethylene.
Mit üblichen Scher-und Stanzvorrichtungen können derartige Stoffe nicht bearbeitet werden, da sie gegebenenfalls unter plastischer Verformung zwischen die Schneidkanten der Werkzeuge hineingezogen werden.With conventional shearing and punching devices, such substances not be machined as they may be subject to plastic deformation between the cutting edges of the tools are drawn in.
Es hat sich dagegen gezeigt, dass gemäss der Neuerung selbst die zähesten Kunststoff-Folien durch ein Schlagmesser, das auf die zu trennenden stücke, welche auf eine harte Unterlage aufgelegt sind, mindestens annähernd senkrecht auftrifft und sie durchschlägt, ohne Schwierigkeit zerschnitten oder perforiert werden können. Zweckmässig besteht dabei sowohl die Unterlage als auch das Schneidwerkzeug mit seiner Schneide, welche beim Schneidvorgang bis zur Unterlage vordringt, aus gehärtetem Stahl. Handelt es sich um Schnitte grösserer Länge, so wird die Schneide des Schneidwerkzeugs vorteilhaft in mehrere, nebeneinander angeordnete, elastisch gelagerte Teile geteilt.It has been shown, however, that according to the innovation, even the toughest Plastic films through a fly knife, which on the pieces to be cut, which are placed on a hard surface, at least approximately vertically and punctures them, can be cut or perforated without difficulty. It is practical if both the base and the cutting tool are included its cutting edge, which penetrates to the base during the cutting process, is made of hardened Stole. In the case of cuts of greater length, the cutting edge of the cutting tool is used advantageously divided into several, adjacently arranged, elastically mounted parts.
In der Zeichnung ist als Ausführungsbeispiel des Neuerungsgegenstandes ein Messerkopf mit unterteiltem Schneidmesser zur Herstellung schlitzförmiger Perforationen einer auf einer Unterlage aufliegenden Kunststoff-Folie raumbildlich dargestellt.In the drawing is an exemplary embodiment of the subject of the innovation a cutter head with a divided cutting knife for producing slot-shaped perforations a plastic film resting on a base is shown in three dimensions.
Die Unterlage besteht aus einer umlaufenden Stahltrommel 10.The base consists of a rotating steel drum 10.
Die auf ihr aufliegende, zu perforierende Polyäthylenfolie ist mit 11 bezeichnet. Über der Folie 11 ist ein auf-und abwärts beweglicher Messerkopf angeordnet, dessen Aufhängung und Antrieb in der Zeichnung nicht dargestellt sind.The polyethylene film to be perforated lying on it is with 11 designated. Above the film 11 is a knife head that can move up and down arranged, the suspension and drive are not shown in the drawing.
Der Messerkopf selbst enthält eine Mehrzahl von nebeneinander angeordneten Schneiden 12, die in einen Halter 13 eingesetzt und in ihm durch feste Zwischenwände 14 voneinander getrennt gehalten sind. Mit ihren den Schneiden abgewandten Enden sitzen die Messer 12 auf einer durchgehenden elastischen Unterlage 15 auf, welche in eine Austragung des Halters 13 eingelegt und durch eine ebenfalls durchgehende Halteschiene 16 gestützt ist. Der Zusammenhalt des Messerkopfes ist durch eine Vorderwand 17 gewährleistet, welche auf in dem Halter 13 verankerte, durch die Halteschiene 16 hindurchtretende Führungsstifte 18 aufgeschoben und durch Schraubenlg, welche die Halteschiene 16 ebenfalls durchdringen, mit dem Halter 13 verschraubt ist. Durch eine an der Vorderwand 17 nach innen vorspringende Haltenase 20, welche in Nuten 21 im Messerhalter 13 und in Nuten 22 in den Messern 12 eingreift, sind die Messer 12 im Messerkopf gehalten. Wesentlich ist dabei, dass die Nuten 22 höher sind als die Nase 20, auf welcher die Messer aufliegen, wenn sie von der Stahltrommel 10 abgehoben sind.The cutter head itself contains a plurality of juxtaposed Cutting edges 12, which are inserted into a holder 13 and in it through fixed partitions 14 are kept separate from each other. With their ends facing away from the cutting edges sit the knife 12 on a continuous elastic base 15, which inserted into a discharge of the holder 13 and also through a continuous Holding rail 16 is supported. The knife head is held together by a front wall 17 guaranteed, which is anchored in the holder 13, by the retaining rail 16 passing through guide pins 18 pushed and screwed through, which also penetrate the holding rail 16, with which the holder 13 is screwed. By a on the front wall 17 inwardly projecting retaining lug 20, which in grooves 21 in the knife holder 13 and in grooves 22 in the knives 12 are the knives 12 held in the cutter head. It is essential that the grooves 22 are higher than the nose 20 on which the knives rest when they are removed from the steel drum 10 are lifted.
Während der Betätigung des Messerkopfes durch Aufschlagen der Schneiden 12 auf die Polyäthylenfolie 11 und die Stahltrommel 10 werden die Messer 12 dagegen innerhalb des durch die Höhe der Nuten 22 festgelegten Bereichs von der Nase 20 der Vorderwand 17 abgehoben und gegen die elastische Unterlage 15 gedrückt, welche dabei verformt wird.During the operation of the cutter head by hitting the cutting edges 12 on the polyethylene film 11 and the steel drum 10, the knives 12 are against it within the area defined by the height of the grooves 22 from the nose 20 the front wall 17 is lifted and pressed against the elastic pad 15, which is deformed in the process.
Bei der Betätigung des Messerkopfes werden der Breite der einzelnen Messerschneiden entsprechende Perforationsschlitze 11'in die Polyäthylenfolie 11 hineingeschlagen und zwar in Abständen, welche durch die Arbeitstakte der verwendeten Maschine bestimmt sind. Da die Polyäthylenfolie 11 je nach dem Abstand zwischen zwei aufeinanderfolgenden Perforationsschlägen mit einer Geschwindigkeit von 50-150 m/Min unter dem Messerkopf fortbewegt werden kann, wird der Messerkopf in der Perforiermaschine zweckmässig pendelnd aufgehängt, um Beschädigungen der zu perforierenden Folien an den Perforationsschlitzen zu vermeiden.When the cutter head is operated, the width of each Knife cut corresponding perforation slots 11 ′ in the polyethylene film 11 knocked in at intervals determined by the working cycles of the used Machine are intended. As the polyethylene film 11 depending on the distance between two successive perforation strokes at one speed can be moved from 50-150 m / min under the cutter head, the cutter head Suspended in the perforating machine in a pendulum fashion to avoid damage to the Avoid perforating foils at the perforation slots.
