Description

Die Erfindung betrifft eine Hochfrequenz-Schweißeinrichtung mit in der Nähe der Elektroden angeordneter, von dem gleichen Druckteil wie diese betätigter Schneidvorrichtung, insbesondere für das Verschweißen und Zuschneiden von Kunststoffolien unterschiedlicher Dicke. The invention relates to a high-frequency welding device with in placed near the electrodes, actuated by the same pressure part as these Cutting device, in particular for welding and cutting plastic films different thickness.

Es sind Schweiß einrichtungen bekannt, die für das Herstellen von Werkstücken aus Kunststofffolien, wie z. B: Hüllen für Ausweise, Brieftaschen u. dgl., verwendet werden. Bei diesen Einrichtungen werden in einem Arbeitsgang Kunstoffolien miteinander verschweißt und in vorgeschriebener Größe zugeschnitten. Das wird bei diesen Vorrichtungen dadurch erreicht, daß die Elektrode bzw. der die Elektrode tragende Druckteil ein Trennmesser oder eine Trennelektrode trägt, die über die wirksame Elektrodenfläche entsprechend der jeweiligen Foliendicke hinausragt. Beim Verschweißen von insbesondere dünnen Folien hat es sich nun als nachteilig erwiesen, daß durch stärkere Schwankungen der Dicke, die bei dünnen Folien bis zu 500/0 betragen können, entweder die Trennung -bei zu dicken Folien - oder die Schweißung - bei zu dünnen Folien - nicht mehr einwandfrei zu erhalten war. There are welding devices known for the manufacture of Workpieces made from plastic films, such as B: Cases for ID cards, wallets, etc. Like., can be used. With these facilities, plastic films are produced in one operation welded together and cut to the prescribed size. That will be at these devices achieved in that the electrode or the electrode bearing pressure part carries a separating knife or a separating electrode, which over the effective electrode area protrudes according to the respective film thickness. At the Welding thin foils, in particular, has now proven to be disadvantageous that due to greater fluctuations in thickness, which are up to 500/0 in the case of thin foils can, either the separation - with too thick foils - or the welding - with too thin foils - could no longer be obtained properly.

Die Erfindung hat die Aufgabe, diese Nachteile zu beseitigen. Bei einer Hochfrequenz-Schweißeinrichtung mit in der Nähe der Elektroden angeordneter, von dem gleichen Druckteil wie diese betätigter Schneidvorrichtung, insbesondere für das Verschweißen und Zuschneiden von Kunststoffolien unterschiedlicher Dicke, ist erfindungsgemäß die Schneidvorrichtung und/oder mindestens eine der Elektroden elastisch mit dem Druckteil verbunden. The invention aims to eliminate these disadvantages. at a high-frequency welding device with arranged in the vicinity of the electrodes, from the same pressure part as this actuated cutting device, in particular for welding and cutting plastic films of different thicknesses, is according to the invention the cutting device and / or at least one of the electrodes elastically connected to the pressure part.

Dadurch wird erreicht, daß unabhängig von der Dicke der jeweiligen Folie die Schweißelektrode bzw. die Schweißelektroden so weit aufeinander gepreßt werden, wie es für eine gute Schweißung notwendig ist, wobei die elastisch mit dem Druckteil verbundenen. Schneidvorrichtungen entsprechend der jeweiligen Dicke der Folie bzw. der Folien zurückfedern können.This ensures that regardless of the thickness of the respective Foil the welding electrode or the welding electrodes pressed together so far as it is necessary for a good weld, the elastic with the Printing part connected. Cutting devices according to the respective thickness of the Foil or foils can spring back.

Die Erfindung wird an Hand eines Ausführungsbeispieles in der Zeichnung näher erläutert. The invention is illustrated using an exemplary embodiment in the drawing explained in more detail.

In der Figur ist an einem Druckteils eine Schweißelektrode 2 befestigt und über eine Feder 3 eine Trennelektrode 4, die durch einen Bolzen 5 geführt wird. Als Gegenelektrode dient in diesem Ausführungsbeispiel ein Tisch 6. Je nach Dicke der zu verschweißenden Folien wird der Druckteil 1 mit der Schweißelektrode 2 abgesenkt, während die Trennelektrode4, die auf die Größe der vorkommenden Foliendicke eingestellt ist, so weit nachgibt, wie es für einen entsprechenden Abstand der Schweißelektroden voneinander notwendig ist. In the figure, a welding electrode 2 is attached to a pressure part and via a spring 3 a separating electrode 4 which is guided through a bolt 5. In this exemplary embodiment, a table 6 serves as the counter electrode. Depending on the thickness of the foils to be welded, the printing part 1 with the welding electrode 2 is lowered, while the separating electrode4, which is adjusted to the size of the film thickness occurring is, yields as much as it is for a corresponding distance between the welding electrodes from each other is necessary.

Selbstverständlich sind die Ausführungsmöglichkeiten der Schweißeinrichtung nach der Erfindung durch das vorliegende Beispiel nicht erschöpft. Beispielsweise läßt sich das Verfahren auch sinngemäß für zwei gleichartig ausgebildete Schweißelektroden mit entsprechend angeordneten Trennelektroden vorteilhaft verwenden, wie überhaupt die Ausbildung und Anordnung der Schneidvorrichtung unabhängig von der jeweiligen Form und der besonderen Ausbildung der Schweißelektroden ist. It goes without saying that the welding equipment can be implemented according to the invention by the present example not exhausted. For example the method can also be used analogously for two similarly designed welding electrodes Use with appropriately arranged separating electrodes advantageously, as at all the design and arrangement of the cutting device regardless of the respective Shape and the special design of the welding electrodes.
