Di«. Erfindung betrifft eine Trennschweißvorrichtung für mehrlagige Verpackungsfolien in Form eines beheizbaren Balkens.The invention relates to a separating and sealing device for multi-layer packaging films in the form of a heatable bar.
Balkenförmige Trennschweißvorrichtungen für Verpackungsfolien sind bereits bekannt, wobei der Balken einstückig ausgebildet ist und gleichzeitig einen Schweißstempel und eine Schneidklinge bildet. Die Balken sind beheizbar und aus einem gut wärmeleitfähigen Material, beispielsweise aus Aluminium, gefertigt. Da insbesondere die Schneidklinge einer starken mechanischen Belastung ausgesetzt ist, weisen die bekannten Vorrichtungen eine geringe Standzeit wegen hohem Verschleiß auf.Bar-shaped separating and welding devices for packaging films are already known, whereby the bar is made in one piece and simultaneously forms a welding stamp and a cutting blade. The bars can be heated and are made of a material with good thermal conductivity, for example aluminum. Since the cutting blade in particular is exposed to strong mechanical stress, the known devices have a short service life due to high wear.
Der Erfindung liegt die Aufgabe zugrunde, eine Trennschweißvorrichtung der bekannten Art hinsichtlich der Verschleißanfälligkeit und einer Erhöhung der Eineatzmöglichkeiten zu verbessern.The invention is based on the object of improving a cutting and welding device of the known type with regard to susceptibility to wear and increasing the possible applications.
- 2 G 6899- 2G6899
Diese Aufgabe wird mit einer Trennschweißvorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß der Balken aus einem den Schweißstempel bildenden Körper besteht» an des« eine separate Schneidklinge angeordnet ist-This object is achieved according to the invention with a separating welding device of the type mentioned at the beginning in that the beam consists of a body forming the welding stamp on which a separate cutting blade is arranged.
Die separate und zweckmäßigerweise auswechselbare Anordnung der Schneidklinge am Balken der Trennschweißvorrichtung erhöht sowohl die Lebensdauer der Anordnung als auch deren Einsatzmöglichkeit. So kann die Schneidklinge beispielsweise aus hochwertigem Stahl gefertigt und dadurch praktisch verschleißfrei sein. Der weniger beanspruchte Schweißstempel kann nach wie vor aus Gewichts- und Wärmeleitfähigkeitsgründen aus Aluminium bestehen und läßt sich wegen der gesonderten Schneidklinge mit seinen Schweißprofilen vielfältiger gestalten; in Sonderfällen auch ohne Schneidklinge als reiner Schweißstempel verwenden. Durch eine einfach auswechselbare Anordnung der Schneidklinge kann diese problemlos gegen eine andere, beispielsweise zur Erzeugung einer perforierten Abrißlinie in den Folien profilierte Klinge ersetzt verden. Dabei kann die Schneidklinge in thermischem Kontakt zum beheizbaren Schweißstempel stehen und dadurch das Durchtrennen der volif>n erleichtern. Der Schweißstempel selbst kann unterschiedlich ausgeführt sein zur Erzeugung verschiedener Schweißnähte oder Schweißstellen. Er kann beispielsweise längsverlaufende Schweißprofile ein- oder beidseitig der Schneidklinge aufweisen, wobei die Anordnung dieser Schweißprofile symmetrisch oder asymmetrisch zur Schneidklinge sain kann. Die Form der Längeprofile ist dabei beliebig.The separate and conveniently replaceable arrangement of the cutting blade on the beam of the cutting and welding device increases both the service life of the arrangement and its possible uses. For example, the cutting blade can be made of high-quality steel and is therefore practically wear-free. The less stressed welding stamp can still be made of aluminum for reasons of weight and thermal conductivity and can be designed in a more versatile way thanks to the separate cutting blade with its welding profiles; in special cases it can also be used without a cutting blade as a pure welding stamp. Thanks to an easily replaceable arrangement of the cutting blade, it can easily be replaced with another blade, for example one profiled to create a perforated tear line in the foil. The cutting blade can be in thermal contact with the heatable welding stamp and thus make it easier to cut through the solid foil. The welding stamp itself can be designed in different ways to create different weld seams or weld points. For example, it can have longitudinal welding profiles on one or both sides of the cutting blade, whereby the arrangement of these welding profiles can be symmetrical or asymmetrical to the cutting blade. The shape of the length profiles is arbitrary.
