Description

Vorrichtung zum Zusammenschweißen thermoplastischer Folien Für die Schweißung von thermoplastischen Folien sind bereits Vorrichtungen bekannt, bei denen die Folien zwischen zwei Klemmschienen derart eingespannt sind, daß nur ihre zu verschweißenden Ränder aus dieser Einspannvorrichtung vorstehen und nur diese vorstehenden Ränder beim Schweißvorgang der direkten Einwirkung eines die Schweißwärme erzeugenden, relativ zu den zu verschweißenden Rändern bewegbaren Werkzeugs ausgesetzt sind.Device for welding together thermoplastic foils For the Welding of thermoplastic films are already known devices at which the foils are clamped between two clamping rails in such a way that only their To be welded edges protrude from this jig and only this protruding edges during the welding process of the direct action of the welding heat generating, exposed relative to the edges to be welded movable tool are.

Die Wirtschaftlichkeit dieser bekannten Vorrichtungen und die Güte der Schweißung läßt sich gemäß der Erfindung durch Konzentration der Schweißwärme an den zu verschweißenden Rändern wesentlich dadurch verbessern, daß das Werkzeug aus einem die zu verschweißenden Ränder der Folien in einer Rille aufnehmenden Schuh besteht, der mit auf beiden Seiten die Klemmschienen umgreifenden Führungsleisten versehen ist. The economy of these known devices and the quality the weld can be made according to the invention by concentrating the welding heat significantly improve at the edges to be welded by the fact that the tool from a shoe receiving the edges of the foils to be welded in a groove consists of the guide rails encompassing the clamping rails on both sides is provided.

Ausführungsbeispiele der Erfindung sind im folgenden Teil der Beschreibung an Hand der Zeichnungen beschrieben. Von den lediglich schematischen Zeichnungen zeigt Fig. t einen Querschnitt durch die neue Vorrichtung, Fig. 2 eine Seitenansicht der in Arbeitsstellung befindlichen Vorrichtung, Fig. 3 eine Draufsicht auf die in ihrer zu Fig. 2 gezeigten Stellung befindliche Vorrichtung und Fig. 4 eine Ausführungsform der Spannvorrichtung. Embodiments of the invention are part of the description below described on the basis of the drawings. From the merely schematic drawings Fig. t shows a cross section through the new device, Fig. 2 shows a side view the device in the working position, Fig. 3 is a plan view of the device located in its position shown in FIG. 2 and FIG. 4 shows an embodiment the jig.

Die beiden Folien 1 und 2 werden so aufeinandergelegt, daß ihre oberen Ränder sich ungefähr decken, und in dieser Lage zwischen den Klemmschienen 3 und 4 so eingespannt, daß die Ränder nur wenig über die Klemmschienen 3, 4 hinausragen. Die Schweißwärme wird durch das als Schuh 5 ausgebildete Werkzeug zugeleitet, das parallel mit den Folienrändern bewegt wird. Die Längsrille 6 dient dabei zur Aufnahme der Ränder. Die Wandung der Rille 6 gibt durch Leitung und Strahlung so viel Wärme an die überstehenden Folienränder ab, daß diese zusammenschmelzen und fest miteinander verbunden werden. The two films 1 and 2 are placed on top of one another that their upper Edges coincide approximately, and in this position between the clamping rails 3 and 4 clamped in such a way that the edges protrude only a little beyond the clamping rails 3, 4. The welding heat is fed through the tool, designed as a shoe 5, which is moved parallel to the edges of the film. The longitudinal groove 6 is used for receiving the edges. The wall of the groove 6 gives so much heat through conduction and radiation on the protruding edges of the film so that they melt together and firmly together get connected.

Der Schuh 5 ist zu seiner Führung auf beiden Seiten mit die Klemmschienen 3, 4 umgreifenden Führungsleisten 7 versehen.The shoe 5 is for its guidance on both sides with the clamping rails 3, 4 encompassing guide strips 7 provided.

An Stelle einer Einspannvorrichtung, die aus zwei starren Klemmschienen besteht, kann auch eine Einspannvorrichtung verwendet werden, bei der die an dem Arbeitstische angebrachte Klemmschiene 3 starr und kräftig ausgeführt ist, während die zweite Klemmschiene 4 konvex gebogen und biegsam ist. Die biegsame Klemmschiene 4 ist mit ihrem einen Ende mittels eines Scharniers an der starren Klemmschiene 3 angelenkt. Zum Einlegen der beiden Folien 1, 2 zwlschen die Klemmschienen 3, 4 wird die biegsame Klemmschiene 4 abgeklappt und nach dem Einlegen so weit gegen die Klemmschiene 3 gebogen, daß der am Ende der Klemmschiene 4 angebrachte Sperrriegel 8 einrastet und dadurch die gestreckte Klemmschiene 4 in der punktiert gezeichneten Klemmstellung festhält. Durch die in spannungslosem Zustande konvexe Form der Klemmschiene 4 und ihre Biegsamkeit wird erreicht, daß die Folien 1, 2 in ihrer ganzen Einspannlänge fest eingeklemmt werden. Instead of a clamping device consisting of two rigid clamping rails exists, a jig can also be used in which the on the Work tables attached clamping rail 3 is rigid and strong while the second clamping rail 4 is convexly curved and flexible. The flexible clamping rail 4 is at one end by means of a hinge on the rigid clamping rail 3 hinged. To insert the two foils 1, 2 between the clamping rails 3, 4 becomes the bendable one Clamping rail 4 folded down and after insertion so far against the Clamping rail 3 bent that the locking bolt attached to the end of the clamping rail 4 8 engages and thereby the stretched clamping rail 4 in the dotted line Clamped position. Due to the convex shape of the clamping rail when de-energized 4 and their flexibility is achieved that the films 1, 2 in their entire clamping length be clamped firmly.

Als Klemmschienen können auch plattenförmige Körper mit vieleckiger oder gekrümmter Umrißform verwendet werden. Im letzteren Fall kann ein Schuh Anwendung finden, dessen auf den Kanten der Platten aufliegende, mit der Rille 6 versehene Fläche entsprechend gekrümmt ist. Plate-shaped bodies with polygonal ones can also be used as clamping rails or curved outline shape can be used. In the latter case, a shoe can be used find, the groove 6 of which rests on the edges of the plates Surface is correspondingly curved.
