Vorrichtung zur Herstellung von mit Gut zu füllenden Packungen aus einem Kunststoffschlauch Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von mit Gut zu füllenden Packungen aus einem in der Hitze schweißbaren, thermoplastischen Kunststoffolienschlauch, z. B. aus Polyvinylchlorid, Polyäthylen, Polyamid, Superpolyamid u. dgl.Device for the production of packs to be filled with goods a plastic hose The invention relates to a device for manufacturing of packs to be filled with good made of a heat-weldable, thermoplastic material Plastic tube, e.g. B. made of polyvinyl chloride, polyethylene, polyamide, super polyamide and the like
Damit die gebildeten Packungen Mundstücke erhalten, ist es bekannt, solche Mundstücke an dem Schlauch in vorbestimmtem Abstand zu befestigen; bei der einen Ausführungsform erfolgt das Aufsetzen der Ausflußtülle bei prall gefülltem Schlauch in der Weise, daß die Elektroden auf beiden Seiten des gefüllten Schlauches angeordnet werden. Es ist ferner bekannt, bei der Bildung des Schlauches zunächst einen Streifen aus thermoplastischem Material zu verwenden, der in Abständen mit Öffnungen versehen wird. In diese Öffnungen werden Gewindenippel mit Flanschen an der Unterseite eingesetzt, wobei die Flansche mit dem Streifen verschweißt werden. Der auf diese Weise mit den Gewindeteilen besetzte Streifen wird sodann mit einem zweiten Streifen zur Herstellung eines schlauchartigen Gebildes an den Längsrändern verschweißt. Bei dieser Ausführungsform erhält man keinen in Längsrichtung nahtlos bleibenden Schlauch.In order for the formed packs to receive mouthpieces, it is known attaching such mouthpieces to the hose at a predetermined distance; in the In one embodiment, the spout is placed on when the spout is bulging Hose in such a way that the electrodes are on both sides of the filled hose to be ordered. It is also known to start with the formation of the hose to use a strip of thermoplastic material spaced with Openings is provided. Threaded nipples with flanges are attached to these openings the underside, the flanges being welded to the strip. The occupied in this way with the threaded parts strip is then with a second strip for producing a tube-like structure on the longitudinal edges welded. In this embodiment, no seamless lengthways are obtained permanent hose.
Zum Bilden von balgartigen Seitenfalten in einer Schlauchbahn ist es ferner bekannt, innerhalb des Schlauches einen eingelegten Kern zu verwenden. Als Festhaltemittel für diesen Kern dienen im wesentlichen Falzbleche bzw. Falzrollen, die in Nuten des Formkerns eingreifen. Hierbei sind die Nuten so ausgebildet, daß der Formkern sich weder vorwärts noch rückwärts bewegen kann. Er wird somit schwimmend in dem Schlauch gehalten. Die noch vorgesehenen magnetischen Haltevorrichtungen dienen dazu, das Eigengewicht des Formkerns zu kompensieren, da die Schlauchbahn im wesentlichen in einer senkrechten Ebene verlaufen soll. In einem anderen bekannten Fall verwendet man ebenfalls einen schwimmend angeordneten Kern in einem Schlauch, wobei der Kern abwechselnd dünner und dicker ausgebildet ist. Hierbei umgreifen die Haltemittel von außen den Kern und sind mit ihrer dem Kern zugekehrten Fläche der Kontur desselben angepaßt. Ein in dieser Weise schwimmend gelagerter Kern hat die Aufgabe, , den von einer Spule abgezogenen und flach liegenden Schlauch zu öffnen.For forming bellows-like gussets in a hose web it is also known to use an inserted core within the tube. The retaining means for this core are essentially folding sheets or folding rollers, which engage in grooves in the mandrel. Here, the grooves are designed so that the mandrel cannot move forwards or backwards. It thus becomes swimming held in the hose. The planned magnetic holding devices serve to compensate for the dead weight of the mold core, as the hose web should run essentially in a vertical plane. In another well-known In this case, a floating core in a tube is also used, wherein the core is made alternately thinner and thicker. Reach around here the holding means from the outside of the core and are with their surface facing the core adapted to the contour of the same. Has a core that is floating in this way the task of opening the hose that has been pulled off a spool and lying flat.
Die Aufgabe der Erfindung ist auf eine vorteilhafte Ausbildung der Vorrichtung zum Anbringen der Mundstücke an der Außenseite eines Folien- ; schlauches von erheblicher Länge gerichtet. Die Erfindung zeichnet sich dadurch aus, daß die Einlage in an sich bekannter Weise als schwimmender Kern ausgebildet ist, wobei die Halteteile der Einlage in einem seitlichen Abstand der Gegenelektroden angeordnet sind. Hierbei können die Halteteile als Rollen ausgebildet sein.The object of the invention is to provide an advantageous embodiment of the Device for attaching the mouthpieces to the outside of a foil; hose of considerable length directed. The invention is characterized in that the Insert is designed as a floating core in a manner known per se, wherein the holding parts of the insert are arranged at a lateral distance from the counter electrodes are. Here, the holding parts can be designed as rollers.
Eine solche Ausbildung der Innenelektrode ermöglicht ein kontinuierliches Herstellen und Anbringen der Ausflußtüllen und ein Herstellen der Einzelpackungen durch Anbringen von Quernähten bei einem Folienschlauch beliebiger, praktisch unbegrenzter Länge in einfacher Weise. Der Folienschlauch kann an der Elektrodenstelle flachgedrückt werden, so daß Tüllen mit verhältnismäßig großen Ansatzkragen leicht aufgebracht werden können. Der Schweißvorgang wird durch die Haltevorrichtung für den schwimmenden Kern, d. h. für die schwimmende Elektrodeneinlage, nicht gestört.Such a design of the inner electrode enables a continuous Manufacture and attachment of the discharge spouts and manufacture of the individual packs by applying transverse seams to a film tube any, practically unlimited Length in a simple way. The film tube can be flattened at the electrode site so that nozzles with relatively large neck collars are easily applied can be. The welding process is carried out by the holding device for the floating Core, d. H. for the floating electrode insert, not disturbed.
Die Einlagen können durch einen Steg geringeren Querschnitts miteinander verbunden sein. Hierbei kann ein biegsamer Steg verwendet werden. Vorteilhaft weist die Elektrodeneänlage einen Dorn zum Durchstehen der Schlauchwand an der Stelle der Öffnung des aufzubringenden Mundstückes auf. An einer anderen Stelle wird zugleich das Mundstück an dem Schlauch angeschweißt. Durch die an der Einlage nachfolgende Verdickung wird die Schlauchfolie von dem Dorn wieder frei, so daß der Schlauch weiterbewegt werden kann. Die Erfindung wird an Hand der in der Zeichnung dargestellten Ausführungsbeispiele erläutert.The inserts can be connected to one another by means of a web of smaller cross-section be connected. A flexible bar can be used here. Advantageously points the electrode system has a mandrel to protrude the hose wall at the point the opening of the mouthpiece to be applied. In another place is at the same time the mouthpiece is welded to the hose. By the following on the insert Thickening, the tubular film is released again from the mandrel, so that the tube can be moved on.
