Die Erfindung bezieht sich auf eine Preß- und Schweißvorrichtung zum Abteilen von Einzelbehältern aus einem mit Flüssigkeit gefüllten Schlauch oder ähnlichen, aus aufeinandergelegten Folien gebildeten Behälter aus thermoplastischem Kunststoff, bestehend aus einem Hochfrequenzelektrodenpaar, von denen wenigstens eine der Elektroden in einem ihre seitlichen Begrenzungsflächen umgebenden und an der Pressung teilnehmenden Körper aus elektrisch nichtleitendem Material über die Preßfläche hinaus verschiebbar geführt ist. Erfindungsgemäß ist diese bekannte Vorrichtung in der Weise ausgebildet, daß zur Aufrechterhaltung einer geschlossenen Preßfläche, unter Anwendung einer an sich bekannten Abschirmung Ider Arbeitsflächen der Elektroden zur Schonung der Kunststoffflächen, der die Elektrode umgebende Preßkörper aus elektrisch nichtleitendem Material eine zur Schweißstelle hin durch eine dünne Wand abgeschlossene, axial verlaufende längliche Kammer aufweist, in der die Elektrode in Richtung zu und von der Preßstelle beweglich verschiebbar ist. The invention relates to a pressing and welding device for dividing individual containers from a hose filled with liquid or similar thermoplastic containers formed from superimposed films Plastic, consisting of a pair of high-frequency electrodes, at least of which one of the electrodes in one of its lateral boundary surfaces surrounding and on the pressing participating body made of electrically non-conductive material over the Press surface is also guided displaceably. This known device is according to the invention designed in such a way that to maintain a closed pressing surface, using a known shield I of the working surfaces of the electrodes to protect the plastic surfaces, the pressed body surrounding the electrode is made of electrical power a non-conductive material closed off by a thin wall towards the welding point, having axially extending elongated chamber in which the electrode in the direction of and is movably displaceable from the press point.
Vorrichtungen zum Abteilen von flüssigkeitsgefüllten Kunststoffschläuchen in Einzelpackungen müssen folgende Funktionen erfüllen: 1. den flüssigkeitsgefüllten Schlauch an der beabsichtigten Schweißstelle so weit zusammenpressen, daß die Flüssigkeit nach der Seite ausweicht und die gegenüberliegenden Wände des Kunststoffschlauches miteinander in Berührung gebracht werden; 2. in der Preßzone eine Schweißnaht herstellen; 3. während der Herstellung der Schweißnaht die Preßfläche flüssigkeitsfrei halten und den Anpreßdruck aufrechterhalten. Devices for dividing liquid-filled plastic hoses in single packs must fulfill the following functions: 1. the liquid-filled Compress the hose at the intended welding point so far that the liquid dodges to the side and the opposite walls of the plastic tube be brought into contact with each other; 2. Create a weld seam in the press zone; 3. Keep the pressing surface free of liquid during the production of the weld seam and maintain the contact pressure.
Zu diesem Zweck sind zahlreiche, mehr oder minder komplizierte Apparaturen entwickelt worden. Die Vorrichtung nach der Erfindung erfüllt die vielseitigen Aufgaben mit einer Einfachheit des apparativen Aufwandes, die bisher noch nicht erreicht war. Sie beruht auf der Kombination einer die Schweißelektrode nicht nur seitlich, sondern auch an ihrer schmalen, als Arbeitsfläche dienenden Unterseite umgebenden Hülse oder Scheide aus elektrisch nichtleitendem Material mit der freien Verschiebbarkeit des Schweißwerkzeuges gegenüber dieser Hülse oder Scheide über eine längere Wegstrecke. Aus der schweizerischen Patentschrift 288 038 war eine Verschiebbarkeit der Elektrode gegenüber der ihr zugeordneten Hülse aus nichtleitendem Material nur um die winzige Wegstrecke der unter der Wärmeentwicklung der Elektrode eintretenden Dickenverminderung der Folienschlauchwandung bekannt. Außerdem war hier die nichtleitende Hülse des Schweißwerkzeuges an dessen Arbeitsfläche offen, so daß das Schweißwerkzeug unmittelbar auf die Schlauchwandung auftraf. Numerous, more or less complicated apparatuses are used for this purpose has been developed. The device according to the invention fulfills the versatile tasks with a simplicity of the equipment that has not yet been achieved was. It is based on the combination of the welding electrode not only on the side, but also on its narrow underside serving as a work surface Sleeve or sheath made of electrically non-conductive material that can be moved freely of the welding tool compared to this sleeve or sheath over a longer distance. From the Swiss patent 288 038 a displaceability of the electrode was compared to its assigned sleeve made of non-conductive material only by the tiny one Distance of the decrease in thickness that occurs when the electrode heats up the tubular film wall known. Also here was the non-conductive sleeve of the Welding tool open at its work surface, so that the welding tool immediately hit the hose wall.
In der Zeichnung ist eine Ausführungsform der Vorrichtung nach der Erfindung dargestellt. Einem Gegenlager 4 aus elektrisch leitendem Material ist ein Preßwerkzeug 1 aus elektrisch nichtleitendem Material gegenübergestellt, das einen axial verlaufenden länglichen Hohlraum 2 aufweist, der an seinem dem Gegenlager zunächstliegenden Ende mit einer nur dünnen Wandung abgeschlossen ist. Innerhalb des Hohlraumes 2 ist die als Schweißwerkzeug dienende Hochfrequenzelektrode 3 selbständig in axialer Richtung verschiebbar angeordnet. In the drawing is an embodiment of the device according to Invention shown. A counter bearing 4 is made of electrically conductive material a pressing tool 1 made of electrically non-conductive material compared, the has an axially extending elongated cavity 2, which at its the counter bearing nearest end is finished with only a thin wall. Within of the cavity 2, the high-frequency electrode 3 serving as a welding tool is independent arranged displaceably in the axial direction.
Das Preßwerkzeug kann aus Preßmasse, Kunststoff, Keramik, Hartgummi od. dgl. hergestellt sein und hat die Form eines schmalen Rechtkants, das zweckmäßig an seinem in Berührung mit dem flüssilgkeitsgefüllten Schlauch zu bringenden Ende verjüngt wird, wie dies in der Zeichnung dargestellt ist. Der flüssigkeits füllte Schlauch 5, 5' wird horizontal über das Gegenlager 4 geführt, und das Preßwerkzeug 1 wird in regelmäßigen Abständen so weit von oben auf den Schlauch herabgesenkt, daß an der Berührungsstelle die Schlauchwandungen unter seitlicher Verdrängung der Flüssigkeit einander genähert und schließlich zur Berührung miteinander gebracht werden. Diese Phase ist in der Zeichnung dargestellt. 5 ist ein bereits einseitig durch eine gleiche Operation abgeteilter Behälter, der nunmehr unter dem Druck des Preßwerkzeuges von dem freien flüssigkeitsgefüllten Schlauchende 5' abgequetscht ist. In diesem Stadium wird die Hochfrequenzelektrode 3 nach abwärts bis zur Kammerunterwand geführt und unter Strom gesetzt, so daß die aufeinandergepreßten Schlauchwandungen an der Berührungsstelle verschweißt werden. The pressing tool can be made of molding compound, plastic, ceramic, hard rubber Od. The like. Be made and has the shape of a narrow square edge that is appropriate at its end to be brought into contact with the liquid-filled tube is tapered like this is shown in the drawing. The liquid filled hose 5, 5 'is guided horizontally over the counter bearing 4, and the pressing tool 1 is lowered from above onto the hose at regular intervals that at the point of contact the hose walls with lateral displacement of the Liquid approached each other and finally brought into contact with each other will. This phase is shown in the drawing. 5 is an already one-sided by the same operation divided container, which is now under the pressure of the Pressing tool squeezed off the free liquid-filled hose end 5 ' is. At this stage, the high-frequency electrode 3 is lowered down to the lower wall of the chamber guided and energized so that the hose walls pressed together be welded at the point of contact.
