Abstract

The transverse welding head for packaging machines using plastic film has an upper jaw (2) and a lower jaw (3). The lower jaw has a counter-strip (5) for the upper jaw on its upper surface which is made from vulcanized rubber (6).

Description

Die vorliegende Erfindung betrifft eine Querschweißeinrichtung einer Folienverpackungsmaschine mit einem in vertikaler Richtung beweglichen beheizten Oberstempel und einem unbeheizten Unterstempel, wobei der Unterstempel eine Gegenkante für den Oberstempel aus einem temperaturbeständigen, elastischen Material aufweist.The The present invention relates to a transverse welding device of a film packaging machine with a vertically movable heated upper punch and an unheated lower stamp, the lower stamp being a Counter edge for The upper punch made of a temperature-resistant, elastic material having.

Derartige Querschweißeinrichtungen sind allgemein bekannt und dienen dazu, eine auf einer Transportbahn befindliche Folie, in der ein Verpackungsgut einliegt, vor und/oder hinter dem Verpackungsgut zu verschweißen und von der Folienbahn zu trennen. Um eine saubere Verschweißung zu erhalten, ist üblicherweise die Gegenkante des Unterstempels aus Silikon hergestellt und zum Schutze der Silikongegenkante mit einem Teflonband überdeckt, das seitlich an dem metallischen Grundkörper befestigt ist. Durch den permanenten Kontakt des Teflonbandes mit dem spitzen und heißen Oberstempel wird dieses beschädigt, so dass nach relativ kurzer Zeit ein Auswechseln erforderlich ist, damit die Qualität der Schweißnaht erhalten bleibt.such Cross welding equipment are well known and serve one on a transport path located film in which a packaged goods, before and / or To weld behind the packaged goods and from the film web to separate. To get a clean weld is common the opposite edge of the lower punch made of silicone and the Cover the silicone counter edge with a Teflon tape covering the is attached laterally to the metallic base body. By the permanent contact of the Teflon tape with the sharp and hot upper punch becomes this one is damaged, so that after a relatively short time a replacement is required, thus the quality the weld preserved.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, eine Möglichkeit vorzuschlagen, mit der die Standzeit des Unterstempels erhöht werden kann.Of the The present invention is therefore based on the object, a possibility to propose to increase the service life of the lower punch can.

Diese Aufgabe wird erfindungsgemäß durch eine Querschweißeinrichtung mit den Merkmalen des Hauptanspruchs gelöst. Eine weitere vorteilhafte Ausgestal tung ist dem Unteranspruch zu entnehmen.These The object is achieved by a Transverse welding device solved with the features of the main claim. Another advantageous Ausgestal device is to be taken from the subclaim.

Gemäß der Erfindung besteht die Gegenkante aus einem Gummimaterial, das elastisch ist und eine ausreichende Hitzebeständigkeit für die beim Schweißen auftretenden Temperaturen aufweist. Überraschenderweise wurde festgestellt, dass damit ohne zusätzliches Schutzband gleich gute Ergebnisse erzielt werden können, obwohl die bekannten Querschweißeinrichtungen bisher das zusätzliche Teflonband verwenden. Mit dem neuen Unterstempel wird somit die Standzeit wesentlich erhöht, wobei das Auswechseln dann gegenüber dem bisherigen Auswechselvorgang etwas aufwändiger ist. Bei einer wesentlichen Erhöhung der Standzeit spielt dies jedoch keine Rolle mehr.According to the invention the counter edge is made of a rubber material that is elastic and sufficient heat resistance for the at welding having occurring temperatures. Surprisingly, it was found that with no additional Guard band same good results can be achieved, though the known transverse welding devices so far the extra Use Teflon tape. With the new lower stamp is thus the Stability substantially increased, with the replacement then opposite the previous replacement process is a little more complex. At a material increase However, this does not matter anymore.

Vorteilhafterweise wird die Gegenkante einfach durch Aufvulkanisieren von Gummi auf den metallischen Grundkörper des Unterstempels realisiert.advantageously, The counter edge is simply by vulcanizing rubber on the metallic body realized of the lower punch.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert, das in der einzigen Figur ist in perspektivischer Ansicht schematisch dargestellt ist. Die Querschweißeinrichtung 1 umfasst einen Oberstempel 2 und einen Unterstempel 3. Der Oberstempel 2 weist auf der Unterseite eine spitze Kante 4 auf und ist beheizt. Wie durch den Pfeil angedeutet, ist der Oberstempel 2 in vertikaler Richtung beweglich. Die durch den Unterstempel 3 gebildete Gegenkante 5 ist flächig ausgebildet und besteht aus einer Schicht 6 aus aufvulkanisiertem Gummi auf einem metallischen Grundkörper 7.The invention will be explained in more detail with reference to an exemplary embodiment, which is shown schematically in a perspective view in the single FIGURE. The transverse welding device 1 includes a topstamp 2 and a lower stamp 3 , The upper stamp 2 has a sharp edge on the underside 4 on and is heated. As indicated by the arrow, the upper punch is 2 movable in the vertical direction. The by the lower stamp 3 formed counter edge 5 is flat and consists of a layer 6 made of vulcanised rubber on a metallic base 7 ,

Diese Querschweißeinrichtung mit dem Oberstempel 2 und dem Unterstempel 3 sind in bekannter Art und Weise mit den dazugehörigen Aggregaten mit einer Folienverpackungsmaschine verbunden.This transverse welding device with the upper punch 2 and the lower stamp 3 are connected in a known manner with the associated units with a film wrapping machine.

Für eine einwandfreie Funktion der Querschweißeinrichtung 1 ist eine ausreichende Härte und Temperaturbeständigkeit der Gegenkante 5 erforderlich. Andererseits soll außerdem auch eine ausreichende Elastizität gewährleistet sein, wie sie durch Gummi bereitgestellt wird. Die Härte des Materials sollte im Bereich von SH 60–80 liegen.For a perfect function of the transverse welding device 1 is a sufficient hardness and temperature resistance of the counter edge 5 required. On the other hand, should also be ensured sufficient elasticity, as provided by rubber. The hardness of the material should be in the range of SH 60-80.
