Abstract
Description
Die Erfindung betrifft ein Verfahren zum rapportgenauen Positionieren von mindestens zwei sich bewegenden Lagen aus Kunststofffolie relativ zueinander, bei dem die Positionen der Lagen mittels einer Sensorik erfasst werden, und eine Vorrichtung zum rapportgenauen Positionieren von mindestens zwei sich bewegenden Lagen aus Kunststofffolie relativ zueinander, insbesondere als Bestandteil einer Maschine zur Herstellung von Verpackungen aus Kunststofffolie, mit einer Sensorik zur Erfassung der Position einer Lage, und eine Maschine zur Herstellung von Verpackungen aus Kunststofffolie.The invention relates to a method for rapport accurate positioning of at least two moving layers of plastic film relative to each other, wherein the positions of the layers are detected by a sensor, and a device for rapport accurate positioning of at least two moving layers of plastic film relative to each other, in particular as Component of a machine for the production of plastic film packaging, with a sensor for detecting the position of a layer, and a machine for producing plastic film packaging.
Heutzutage werden vorwiegend zum Detektieren einer Position eines Ist-Zustandes von mehreren Lagen aus Kunststofffolie als Sensorik beispielsweise Fotozellen verwendet, die beispielsweise Druckmarken auf den einzelnen Lagen aus Kunststofffolie erkennen.Nowadays, for example, photo cells are mainly used to detect a position of an actual state of several layers of plastic film as sensors, which recognize, for example, print marks on the individual layers of plastic film.
Bekannt ist aus der
Nachteilig ist, dass die Korrektur der Position des Ist-Zustandes in einen Soll-Zustand von Lagen aus Kunststofffolie heutzutage mit Hilfe teurer, zusätzlicher Vorrichtungen erfolgt.The disadvantage is that the correction of the position of the actual state in a desired state of layers of plastic film nowadays takes place with the help of expensive, additional devices.
Aufgabe der Erfindung ist es daher, dass bei einer Abweichung von der Relativposition zueinander die Position einer Lage zu der Position der anderen Lage durch eine durch Dehnen oder Entspannen verursachte Längenänderung korrigiert wird.The object of the invention is therefore that when a deviation from the relative position to each other, the position of one layer is corrected to the position of the other layer by a change in length caused by stretching or relaxing.
Vorteilhaft ist, dass die mit Hilfe der Schwinge erzeugten Dehnungen oder erzeugten Entspannungen in den jeweiligen sich bewegenden Lagen aus Kunststofffolie die einzelnen Lagen schnell, kostengünstig und einfach rapportgenau relativ zueinander positionieren.It is advantageous that the strains produced with the help of the rocker or depressions generated in the respective moving layers of plastic film position the individual layers quickly, inexpensively and easily rapport accurate relative to each other.
Das Dehnen oder Entspannen einer Lage erfolgt bevorzugt mittels einer von der Lage umschlungenen auslenkbaren Schwinge.The stretching or relaxing of a layer preferably takes place by means of a deflectable rocker looped around by the layer.
Die Position einer Lage wird bevorzugt mittels eines optischen Sensors bestimmt, der die Position einer Druckmarke und/oder produktspezifischen Merkmals, insbesondere einer Schweißnaht, detektiert.The position of a layer is preferably determined by means of an optical sensor which detects the position of a print mark and / or product-specific feature, in particular a weld seam.
Die Auslenkung der Schwinge erfolgt bevorzugt mittels eines Pneumatikzylinders, der über ein Proportionalventil steuerbar ist.The deflection of the rocker is preferably carried out by means of a pneumatic cylinder which is controllable via a proportional valve.
In der Figur wird ein bevorzugtes Ausführungsbeispiel gemäß der Erfindung dargestellt. Es zeigtIn the figure, a preferred embodiment according to the invention is shown. It shows
Nachfolgend werden ein erfindungsgemäßes Verfahren und eine Vorrichtung zu seiner Durchführung näher beschrieben.In the following, a method according to the invention and a device for carrying it out will be described in more detail.
