Abstract
Description
Die Erfindung betrifft eine Thermoformmaschine nach dem Oberbegriff des Anspruchs 1 und zwei Verfahren zum lagegenauen Transportieren einer Folienbahn in dieser Thermoformmaschine.The The invention relates to a thermoforming machine according to the preamble of claim 1 and two methods for accurate transport a film web in this thermoforming machine.
Bei einer Thermoformmaschine mit einer Formstation und einer nachgeschalteten Stanzeinrichtung, mit der meist behälterförmige Teile geformt werden – und die deshalb der Einfachheit wegen nachfolgend generell Behälter genannt werden – besteht prinzipiell das Problem des Auftretens von Stanzversatz. Je nach Behälterform und geplanter Verwendung der Behälter darf dieser Stanzversatz ein bestimmtes Maß nicht überschreiten. Werden die Behälter vor dem Ausstanzen gefüllt und mit einer Deckfolie versiegelt, liegt eine zur Verpackungsmaschine erweiterte Thermoformmaschine vor.at a thermoforming machine with a forming station and a downstream Punching device, are formed with the most container-shaped parts - and the therefore, for the sake of simplicity, hereinafter generally called a container be - exists in principle the problem of the occurrence of punching offset. Depending on the container shape and planned use of the containers this punching offset must not exceed a certain level. Are the containers before filled the punching and sealed with a cover sheet, one lies to the packaging machine advanced thermoforming machine.

der
Nachteilig bei dieser Gestaltung der Folientransporteinrichtung ist es, dass einer unterschiedlichen Länge der beiden Transportketten durch diese Lösung nicht in ausreichender Weise Rechnung getragen wird, wie in den beiden nachfolgenden Abschnitten näher erklärt wird. Diese Unterschiede in der Länge der Transportketten sind einerseits fertigungsbedingt. Es gibt für die Genauigkeit von Ketten eine Norm, die zwar geringe Toleranzen pro Kettenglied zulässt, doch addieren sich diese Toleranzen, da viele Kettenglieder zu einer Folientransporteinrichtung benötigt werden. Einen weiteren Einfluss hat die Temperatur der Transportketten, die zu einer Längenveränderung führt. Zum einen durch den Unterschied zwischen dem Start der Thermoformmaschine oder Verpackungsmaschine aus kaltem Zustand und dem Betriebszustand, wobei sich während des Betriebes unterschiedliche Temperaturen der beiden Transportketten aus verschiedenen Gründen ergeben können. Bei einem Abstand von 2000 mm zwischen Form – und Stanzstation der Thermoformmaschine bedeutet ein Temperaturunterschied zwischen den Transportketten von 30°C einen Längenunterschied von ca. 1 mm. Ein dritter Faktor einer unterschiedlichen Transportkettenlänge ist eine unterschiedliche Reibung in den Führungen, die zu einer unterschiedlichen Dehnung und zu unterschiedlichem Verschleiß und dies wiederum zu einer unterschiedlichen Länge führt.adversely In this design of the film transport device is that a different length the two transport chains by this solution is not sufficient Is taken into account, as in the two subsequent sections is explained in more detail. These differences in length The transport chains are on the one hand production-related. It gives for the accuracy of chains a standard, although small tolerances per chain link allows, but add these tolerances, as many links to a Film transport device needed become. Another influence is the temperature of the transport chains, the to a change in length leads. On the one hand by the difference between the start of the thermoforming machine or packaging machine from the cold state and the operating state, being during the operation of different temperatures of the two transport chains for various reasons can result. At a distance of 2000 mm between the forming and punching station of the thermoforming machine means a temperature difference between the transport chains of 30 ° C a difference in length of about 1 mm. A third factor of a different transport chain length is a different friction in the guides, leading to a different Elongation and to different wear and this in turn to a different length leads.
Wenn aber die beiden Transportketten eine unterschiedliche Länge haben, führt diese zu einem unterschiedlichen Weg der beiden Transportketten, da die Kettenräder alle synchron bewegt werden und damit pro Transportschritt eine bestimmte Anzahl von Kettengliedern verschoben wird, unabhängig von der Länge dieser Anzahl von Kettengliedern.If but the two transport chains have a different length, leads this to a different way of the two transport chains, since the sprockets All are moved synchronously and thus one step per transport step certain number of chain links is shifted, regardless of the length of this Number of chain links.
Beispiel: Werden zwischen Formstation und Stanzstation 200 Kettenglieder – auf mehrere Takte verteilt – transportiert und hat die Transportkette insgesamt auf einer Seite der Folienbahn eine Länge von 2000 mm und auf der anderen Seite eine Länge von 2002 mm, so wird die Folienbahn auf einer Seite 2 mm weiter transportiert als auf der anderen Seite, was einen entsprechenden Verzug der Folienbahn und damit eine Abweichung der Lage der eingeformten Behälter oder Verpackungen zur Folge hat.Example: Be 200 chain links between mold station and punching station - on several Clocks distributed - transported and has the entire transport chain on one side of the film web a length of 2000 mm and on the other hand a length of 2002 mm, then the Film web transported on one side 2 mm further than on the other side, causing a corresponding distortion of the film web and thus a deviation of the position of the molded container or Packaging results.

Der Erfindung liegt die Aufgabe zugrunde, eine Folientransporteinrichtung zum Transportieren einer Folienbahn in einer Thermoformmaschine dahingehend zu verbessern, dass auf eine unterschiedliche Länge der beiden Transportketten reagiert und ein Stanzversatz aufgrund dieser unterschiedlichen Länge ausgeglichen werden kann. Auch der Ausgleich eines Verzugs der Folienbahn durch Folienschrumpf sollte möglich sein.Of the Invention is based on the object, a film transport device for transporting a film web in a thermoforming machine to improve that to a different length of the both transport chains react and a punching offset due to this different length can be compensated. Also the compensation of a delay of the film web by shrinking the film should be possible.
Gelöst ist diese Aufgabe bei einer Thermoformmaschine durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale. Die Verfahren sind gekennzeichnet durch die in den nebengeordneten Ansprüchen 7 und 9 angegebenen Maßnahmen. Weiterbildungen sind Gegenstand der jeweiligen rückbezogenen Ansprüche.This is solved Task in a thermoforming machine by the characterizing Part of claim 1 specified features.
