Description
Vorrichtung zum Perforieren von Materialbahnen Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Perforieren von Materialbahnen. Als Materialbahnen kommen insbesondere Kunststoffolien und flachliegende Kunststoffolienschläuche, sowie auch Metallfolien, metallkaschiertes oder anderes beschichte tes Papier in Betracht.
Neben bereits bekannten Perforierungsvorrichtungen mit zwischen Stift- und Lochwalzen bzw. Walzen mit aufgebrachten Patrizen- und Matrizenoberflächen, durch laufenden Folien, ist auch schon eine Vorrichtung mit zwei rotierenden Scheiben, wovon die eine, eine auf ihrem Umfang als Matrize dienende Löcher besitzt und die andere auf ihrem Umfang herausstehende, durch Schultern getragene nebeneinander liegenden Kugeln trägt, bekannt.
Alle diese bekannten Perforiervorrich tungen haben aber den Nachteil, dass man den einzelnen Lochabstand in der Längsrichtung der Folie überhaupt nicht und in der Querrichtung nur sehr schwer oder ungenügend verändern kann.
Diesen Nachteil behebt die erfindungsgemässe Vor richtung durch eine über der Materialbahn und der darunter befindlichen Matrize mit einem kleineren Loch als der Kugeldurchmesser angeordneten, durch Schlag feder betätigten Kugel als Patrize.
Im folgenden ist ein Ausführungsbeispiel der erfin dungsgemässen Vorrichtung anhand einer dasselbe in einem senkrechten Längsschnitt darstellenden Zeichnung näher erläutert.
Der über der Materialbahn 1 angeordnete Teil der Vorrichtung besteht aus einer stufenlos angetriebenen Nockenwelle 2, welche in nicht dargestellten Lagern läuft. Auf der Nockenwelle 2 sind je nach der Breite der zu perforierenden Materialbahn 1 bis zu einem verstellbaren Mindestabstand von 4 cm von Mitte zu Mitte eine Mehrzahl von Nocken 3 befestigt. Die Steuer kurve 4 des Nockens 2 hebt den Winkelhebel 5 und spannt dadurch die Schlagfeder 6.
Beim Ausklinken des Winkelhebels 5 bzw. des Auslösens der Schlagfeder 6 beim höchsten Punkt 4a der Steuerkurve 4 schlägt der Stift schnell und hat auf die durch einen Schulter- ring 8a gehaltene Kugel 8 auf die unter der Kugel laufende Folienbahn 1 und stanzt mittels der unter der Materialbahn angeordneten, auf den Kugeldurchmesser abgestimmten Matrize 9, welche mit einer kreisrunden Bohrung versehen ist, ein entsprechend grosses Loch. Der Abfall bzw. Lochbutzen wird durch die erweiterte Boh rung 10 nach unten mit oder ohne Saugluft abgeführt.
Durch die in Querrichtung der Materialbahn 1 im Ab stand bis mindestens 4 cm zu einander verstellbaren einzelnen Elemente der Vorrichtung und der stufen losen Variierung der Drehzahl der Nockenwelle bei kontinuierlicher Laufgeschwindigkeit der Materialbahn kann die Lochdistanz zusätzlich in Laufrichtung der Materialbahn von 3 bis 10 cm stufenlos verändert werden.
Der Winkelhebel 5 ist in einem Bock 11 gelagert, welcher mittels der Schraube 12 am Gestellrahmen 13 oben befestigt ist. Der Stift 7 hat an seinem oberen Ende einen Mitnehmerquerstift 14, welcher durch das Gabelende 15 des Winkelhebels 5 wie beschrieben be tätigt wird. Mit der verstellbaren Gewindebüchse 16 wird die Kraft der Schlagfeder 6 reguliert. Der Ring 17 ist der Anschlag sowohl für die Schlagfeder 6 als auch für die Dämpfungsfeder 18. Die Führungsbüchse 19 ist zugleich der untere Anschlag der Dämpfungsfeder 18.
Die Matrize 9 selbst ist mit einer verstellbaren Gewindebüchse 20 befestigt, welche durch eine Maden schraube 21 am unteren Gestenrahmen 13 festgehalten wird. Mit dieser Vorrichtung kann also ein Mindest- Lochabstand in Querrichtung der Materialbahn von 4 cm und in der Laufrichtung der Materialbahn von 3 cm erreicht werden, wobei der Maximallochabstand in Querrichtung nur durch die Folienbreite begrenzt ist und der Maximallochabstand in Laufrichtung bis 10 cm betragen kann.
Device for perforating webs of material The present invention relates to a device for perforating webs of material. As material webs in particular plastic films and flat-lying plastic film tubes, as well as metal films, metal-laminated or other coated paper come into consideration.
In addition to already known perforation devices with between pin and hole rollers or rollers with applied male and female surfaces, through running foils, there is also a device with two rotating disks, one of which has holes serving as a die on its circumference and the other carries protruding balls carried by shoulders and lying next to each other, known.
However, all these known Perforiervorrich lines have the disadvantage that you can not change the individual hole spacing in the longitudinal direction of the film and very difficult or insufficient in the transverse direction.
This disadvantage is remedied by the device according to the invention by a spring-actuated ball as a male die, which is arranged above the material web and the die below with a hole smaller than the ball diameter.
In the following an embodiment of the device according to the invention is explained in more detail with reference to a drawing showing the same in a vertical longitudinal section.
The part of the device arranged above the material web 1 consists of a steplessly driven camshaft 2 which runs in bearings (not shown). A plurality of cams 3 are attached to the camshaft 2, depending on the width of the material web 1 to be perforated, up to an adjustable minimum distance of 4 cm from center to center. The control curve 4 of the cam 2 lifts the angle lever 5 and thereby tensions the mainspring 6.
When the angle lever 5 is released or the mainspring 6 is released at the highest point 4a of the control cam 4, the pin strikes quickly and hits the ball 8 held by a shoulder ring 8a on the film web 1 running under the ball and punches using the under the Material web arranged, matched to the ball diameter die 9, which is provided with a circular bore, a correspondingly large hole. The waste or slug is discharged through the expanded Boh tion 10 downwards with or without suction air.
Due to the individual elements of the device that were adjustable up to at least 4 cm to each other in the transverse direction of the material web 1 and the stepless variation of the speed of the camshaft with continuous running speed of the material web, the hole distance can also be continuously varied in the running direction of the material web from 3 to 10 cm will.
The angle lever 5 is mounted in a bracket 11 which is fastened by means of the screw 12 to the frame 13 above. The pin 7 has at its upper end a driving transverse pin 14 which is actuated by the fork end 15 of the angle lever 5 as described be. With the adjustable threaded bushing 16, the force of the main spring 6 is regulated. The ring 17 is the stop both for the main spring 6 and for the damping spring 18. The guide bush 19 is also the lower stop of the damping spring 18.
The die 9 itself is attached to an adjustable threaded bushing 20 which is held in place on the lower gesture frame 13 by a grub screw 21. With this device, a minimum hole spacing in the transverse direction of the material web of 4 cm and in the running direction of the material web of 3 cm can be achieved, whereby the maximum hole spacing in the transverse direction is only limited by the film width and the maximum hole spacing in the running direction can be up to 10 cm.
