Rohrförmigen biegsamer Behälter aus thermoschweißbarem Material sowie Verfahren und Werkzeug zu dessen HerstellungTubular flexible container made of thermo-weldable Material as well as process and tool for its production

Die Erfindung betrifft einen rohißrmigen, geschmeidig biegsamen bzw. elastischen oder dehnbaren Behälter aus thermoschweißbarem Material, welcher aus einer rohrförmigen Hülle und einem mit letzterer verbundenen Ansatz- oder Kopfstück besteht.The invention relates to a raw, pliable flexible or elastic or expandable container made of thermo-weldable material, which from a tubular sheath and a neck or head piece connected to the latter.

Ferner bezieht sich die Erfindung auf ein Verfahren zur Verbindung der rohrförmigen Hülle mit dem Ansatz- oder Kopfstück sowie auf ein Werkzeug, welchesThe invention also relates to a method for connecting the tubular casing to the attachment or head piece and to a tool which

zur Herstellung eines solchen Behälters bzw. zur Durchführung des Herstellungsverfahrens besonders geeignet ist.for the production of such a container or for carrying out the production process in particular suitable is.

Es ist bekannt, Teile aus thermoschweißbarem Material, insbesondere aus Kunststoff wie z.B. Polyamid oder Polyäthylen, durch Reibschweißen zu verbinden. Die bisher bekannten Reibschweißmethoden sind aber zur Herstellung eines rohrförmigen Behälters mit Ansatz- oder Kopfstück wenig geeignet, weil hierbei durch Reibung der äußeren Fläche des Ansatz- oder Kopfstückes an einem unbeweglichen Druckwerkzeug Staub entwickelt wurde, wodurch eine umständliche und kostspielige Reinigung dieser Behälter erforderlich wurde.It is known to make parts from thermoweldable Material, in particular made of plastic such as polyamide or polyethylene, to be joined by friction welding. The previously known friction welding methods are, however, for the production of a tubular container with attachment or head piece is not very suitable because this is caused by friction of the outer surface of the attachment or head piece Dust has been developed on an immobile printing tool, making cleaning cumbersome and costly this container became necessary.

Der Erfindung liegt die Aufgabe zugrunde, einen rohrförmigen Behälter der genannten Art und ein Herstellungsverfahren sowie Werkzeuge hierfür zu schaffen, wodurch die unerwünschte Staubentwicklung vermieden werden kann.The invention is based on the object of a tubular container of the type mentioned and a manufacturing method as well as to create tools for this purpose, thereby avoiding the undesired generation of dust can be.

Diese EjcflnüiHHg Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß das Ansatz- oder Kopfstück mit seinem Rand durch Reibschweißen an die Wandung der rohrförmigen Hülle angeschweißt wird.This objective is achieved according to the invention essentially solved in that the neck or head piece with its edge by friction welding to the Wall of the tubular shell is welded.

409807/0918 _ _409807/0918 _ _

Dadurch wird erreicht, daß jegliche Reibung zwischen dem Ansatz- oder Kopfstück und den Werkzeugen und damit eine Staubbildung vermieden werden kann, weil eine Reibung während des ReibschweißVorganges'nur zwischen der Wandung der rohrförmigen, vorzugsweise thermoplastischen Hülle und der anzuschweißenden Zone des Ansatz- oder Kopfstückes stattfindet.This ensures that any friction between the attachment or head piece and the tools and thus dust formation can be avoided because friction during the friction welding process only occurs between the wall of the tubular, preferably thermoplastic shell and the zone of the attachment to be welded or head piece takes place.

Ein vorteilhaftes Verfahren zur 2 Herstellung eines solchen rohrförmigen Behälters besteht erfindungsgemäß darin, daß auf das Ansatz- oder Kopfstück in Axialrichtung ein Druck ausgeübt wird, durch den der ursprüngliche Durchmesser des Ansatz- oder Kopfstückes so*vergrößert wird, daß sein Rand mit der Wandung der rohrförmigen Hülle in reibende Berührung kommt. Die rohrförmige Hülle kann hierbei erfindungsgemäß durch ein starres bzw. feststehendes, äußeres oder inneres Werkzeug in einem Gehäuse auf dem Niveau der Reibschweißoperation festgehalten werden.According to the invention, there is an advantageous method for producing such a tubular container in that a pressure is exerted on the extension or head piece in the axial direction, through which the original diameter of the neck or head piece is increased so * that its edge with the wall of the tubular sheath comes into rubbing contact. The tubular casing can hereby according to the invention a rigid or fixed, external or internal tool in a housing at the level of the friction welding operation be held.

Vorteilhaft kann man erfindungsgemäß zur Ausführung dieses Verfahrens ein rotierendes Anschlagwerkzeug verwenden, welches z.B. auf einem unbeweglichen Dorn im Inneren der rohrförmigen Hülle gelagert ist. Der dieses Anschlagwerlzzeuges ist mit einer nach außenAccording to the invention, a rotating stop tool can advantageously be used to carry out this method use, which is e.g. mounted on an immovable mandrel inside the tubular casing. Of the this stop tool is with one to the outside

abgeschrägten Randzone versehen. Diese Abschrägung ermöglicht es, die Masse des Ansatz- oder Kopfstückes, dessen innere Seite vorteilhaft in Bezug auf die Achse des Behälters abgeschrägt sein kann, seitlich gegen die rohrförmige Wandung der Hülle zu pressen, während der Ausführung des Reibschweißens, welche durch den Axialdruck bewirkt wird, der dadurch hervorgerufen wird, daß sich das Anschlagwerkzeug und ein drehbares Druckwerkzeug gegenüberstehen. In einem solchen Werkzeug wird das Ansatz- oder Kopfstück des Behälters zwischen dem drehbaren Druckwerkzeug und dem drehbaren Anschlagwerkzeug angebracht, von denen mindestens eines in Axialrichtung beweglich gelagert ist.beveled edge zone. This bevel allows the mass of the attachment or head piece, the inner side of which can advantageously be beveled with respect to the axis of the container, laterally against to press the tubular wall of the shell while the execution of the friction welding, which is caused by the axial pressure that is caused by it is that the stop tool and a rotatable pressure tool face each other. In such a tool becomes the neck or head piece of the container between the rotatable pressure tool and the rotatable one Attached stop tool, of which at least one is movably mounted in the axial direction.

Diese Werkzeuge befinden sich vorteilhaft in. einem nicht drehbaren Gehäuse, in dessen Inneren das Druckwerkzeug unter der Wirkung eines beweglichen Elementes axial verschiebbar ist. Das nicht rotierende Gehäuse ist mit einer Eintrittsöffnung und einer Austrittsöffnung für Preßlufdversehen, welche gewissermaßen zur Schmierung des zentralen, dreh- und verschiebbaren Druckwerkzeuges dient.These tools are advantageously located in a non-rotatable housing, inside which the Pressure tool is axially displaceable under the action of a movable element. The non-rotating one Housing has an inlet opening and an outlet opening for compressed air accidentally, which to a certain extent serves to lubricate the central, rotatable and displaceable pressure tool.

Die rohrförmige Hülle kann entweder innerhalb eines starren Mantels oder auf einem feststehendenThe tubular sheath can either be inside a rigid jacket or on a stationary one

In diesem Fall hält das Gehäuse außen den Teil der rohrförmigen Hülle aufrecht, welcher der Reibschweißung ausgesetzt ist.Born, over which the cover is slipped, attached will. In this case, the housing maintains that part of the tubular shell which is the friction weld on the outside is exposed.
