Die Erfindung betrifft eine Vorrichtung zum Aufbringen eines als Verstärkungshülse dienenden Rohrabschnittes aus thermoplastischem Kunststoff auf das Ende eines thermoplastischen Kunststoffrohres, wobei der Rohrabschnitt und das Rohrende vor dem Aufbringen erwärmt werden. The invention relates to a device for applying a as Reinforcing sleeve serving pipe section made of thermoplastic material the end of a thermoplastic plastic pipe, the pipe section and the Tube end to be heated before application. Es sind verschiedene Methoden bei der Herstellung von Steckmuffen an thermoplastischen Rohren, z. B. aus Hart-PVC, bekannt. Da bei Steckmuffen für Druckrohre eine ausreichend dicke Rohrwand im Bereich der Muffe vorhanden sein muß, ist es bekannt, das Rohrende durch Verstärkungshülsen, die im angewärmten Zustand auf das erwärmte Rohrende geschoben werden, auf die erforderliche Wandstärke zu bringen. There are different methods of making push-fit sleeves on thermoplastic pipes, e.g. B. made of rigid PVC, known. As with push-in sleeves for Pressure pipes there must be a sufficiently thick pipe wall in the area of the socket, it is known that the pipe end by reinforcing sleeves, which in the heated state be pushed onto the heated pipe end towards the required wall thickness bring. Rohrende und Verstärkungshülse werden anschließend gemeinsam zu einer Steckmuffe verformt (deutsche Patentschrift 1172418). Das Anwärmen der Rohrenden erfolgte in einem geeignet ausgebildeten Ofen. Die als Verstärkungshülse dienenden Rohrabschnitte wurden in einem Wärmeschrank oder ähnlichen Anwärmevorrichtungen erwärmt und anschließend zum Aufschieben auf das erwärmte Rohr zu diesem transportiert. Für eine weitgehende vollautomatische Rohrverbindungsmuffenfertigung ist dieses Verfahren ungeeignet. The pipe end and reinforcement sleeve then become one together Deformed plug-in socket (German patent specification 1172418). The heating of the pipe ends took place in a suitably designed oven. The ones used as reinforcement sleeves Sections of pipe were placed in a heating cabinet or similar heating device heated and then to slide on the heated pipe this transported. For a largely fully automatic pipe connection socket production this is Procedure unsuitable. Die Aufgabe der Erfindung besteht daher darin, eine Vorrichtung zu schaffen, die es bei geringem Platzbedarf ermöglicht, die Rohrabschnitte in einer automatischen Fertigungsstraße sowohl zu erwärmen als auch auf das Rohrende aufzuschieben. The object of the invention is therefore to provide a device create, which allows the pipe sections in a small space requirement automatic production line both to heat and to push onto the pipe end. Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß ein den zu erwärmenden Rohrabschnitt in seiner ganzen Länge aufnehmendes beheizbares Gefäß vorgesehen ist, daß das Gefäß um eine horizontale Achse, die ihrerseits in einem horizontal verfahrbaren Gestell angeordnet ist, in eine mit dem Rohr koaxiale Lage schwenkbar ist und daß eine Ausstoßvorrichtung an dem Gefäß derart angeordnet ist, daß der erwärmte Rohrabschnitt auf das durch eine Haltevorrichtung zentrierte Rohrende aufschiebbar ist. This object is achieved according to the invention in that a to heating tube section receiving heatable vessel in its entire length it is provided that the vessel around a horizontal axis, which in turn in a horizontally movable frame is arranged in a coaxial position with the pipe is pivotable and that an ejector device is arranged on the vessel in such a way that the heated pipe section on the centered by a holding device pipe end can be postponed. Nach einer weiteren Ausgestaltung der Erfindung ist zusätzlich zu dem beheizbaren Gefäß ein weiteres, um dieselbe Achse schwenkbares beheizbares Gefäß zum Erwärmen des Rohrendes vorgesehen. According to a further embodiment of the invention is in addition to the heatable vessel is another heatable vessel that can be pivoted about the same axis intended for heating the pipe end. Mit der erfindungsgemäßen Anlage ist es möglich, innerhalb einer automatischen Fertigungsstraße Rohrende und Rohrhülse ohne manuelle Betätigung anzuwärmen und für die nachfolgende Verformung vorzubereiten. Durch die Anordnung der beheizbaren Gefäße für das Rohrende und den Rohrabschnitt in einem gemeinsamen Gestell ergibt sich weiterhin der Vorteil, daß die Erwärmung gleichzeitig erfolgen kann und außerdem innerhalb der Fertigungsstraße der Platzbedarf erheblich verringert werden kann. With the system according to the invention, it is possible within a automatic production line to heat the pipe end and pipe sleeve without manual operation and prepare for the subsequent deformation. Due to the arrangement of the heatable Vessels for the pipe end and the pipe section results in a common frame there is still the advantage that the heating can take place at the same time and also the space requirement within the production line can be reduced considerably. Zwecks Anpassung an die Rohrform sind die Heizräume der Gefäße ringförmig ausgebildet, wobei innerhalb des Ringraumes des Gefäßes, das den Rohrabschnitt aufnimmt, ein Dornvorsatz vorgesehen sein kann.In order to adapt to the pipe shape, the boiler rooms of the vessels are ring-shaped formed, wherein within the annular space of the vessel that receives the pipe section, a mandrel attachment can be provided. Durch diesen Dornvorsatz werden etwaige Deformierungen des erwärmten Rohrendes beseitigt, und der Rohrabschnitt kann ohne Schwierigkeiten auf das Rohrende geschoben werden. Through this mandrel attachment, any deformations of the heated Eliminated pipe end, and the pipe section can be easily on the pipe end be pushed. Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die beheizbaren Gefäße in einem rechten Winkel zueinander angeordnet und um 900 schwenkbar. Ein Magazin zur Aufnahme der Rohrabschnitte kann oberhalb des Gestells vorgesehen sein. Hierdurch wird erreicht, daß die Rohrabschnitte direkt in das beheizbare Gefäß gegeben werden können und nach dem Schwenken des Gefäßes um 900 auf das Rohrende aufgeschoben werden können. According to a further advantageous embodiment of the invention are the heatable vessels are arranged at right angles to each other and at 900 pivotable. A magazine for receiving the pipe sections can be located above the frame be provided. This ensures that the pipe sections directly into the heatable Vessel can be given and after swiveling the vessel by 900 on the end of the pipe can be postponed. Die Erfindung soll an Hand der Zeichnungen näher erläutert werden. Dabei zeigt F i g. 1 eine schematische Darstellung der erfindungsgemäßen Vorrichtung im Schnitt, Fig. 2 die Vorrichtung mit zwei beheizbaren Gefäßen, wobei die Stellung zur Aufnahme des Rohrabschnittes wiedergegeben ist, und Fig.3 das Aufschieben des erwärmten Rohrabschnittes auf das Rohrende.
