Description

Nr. 391 295No. 391 295

Die Erfindung bezieht sich auf eine Vorrichtung zum Stumpfschweißen längsgenuteter Kunststoffprofile für Fenster od. dgl., mit wenigstens einem Schweißkopf, der zwei relativ zueinander in einer Aufspannebene verschiebbare Profilaufspanneinheiten und einen zwischen die auf Gehrung geschnittenen Enden zweier zu verschweißender Profile einführbaren Heizspiegel aufweist.The invention relates to a device for butt welding longitudinally grooved plastic profiles for windows or the like, with at least one welding head which has two profile clamping units which can be displaced relative to one another in a clamping plane and a heating mirror which can be inserted between the miter-cut ends of two profiles to be welded.

Profile aus thermoplastischen Kunststoffen, vorzugsweise extrudierte Polyvinylchlorid (PVC)-Profile, werden zur Herstellung von Fenstern, Türen, Rahmen u. dgl. Bauteilen allgemein durch Stumpfschweißen miteinander verbunden, wozu es bereits Ein- oder Mehrkopfschweißvoirichtungen verschiedener Ausführungen gibt. In diesen Vorrichtungen werden pro Schweißkopf zwei Profile miteinander verschweißt, indem die in den Profilaufspanneinheiten festgeklemmten Profile durch entsprechendes Verschieben dieser Aufspanneinheiten stimseitig an einen zwischen die Profilenden eingefahrenen Heizspiegel bis zum Anschmelzen angedrückt und dann nach Entfernen des Heizspiegels die plastifizierten Profilenden zusammengepreßt werden, so daß sich je nach Anzahl der Schweißköpfe ein oder mehr Schweißverbindungen gleichzeitig herstellen lassen. Da zum Anschmelzen der Profilenden die bekannten, im wesentlichen rechteckigen Heizspiegel, die normal zur Aufspannebene zwischen die Profilenden eingeführt werden, plan an deren Stirnflächen anliegen müssen, dürfen die Profile keine überstehenden Teile aufweisen oder aufnehmen, so daß von vornherein ein Verschweißen zweier Profile mit bereits in die dazu vorgesehene Längsnut eingelegter Scheibe od. dgl., die ja das Einführen des Heizspiegels zwischen die Profilenden verhindern würde, unmöglich ist Die Rahmenprofile müssen daher offene Nuten bilden, die nach dem Zusammenschweißen der Rahmen das Einlegen der Scheiben erlauben, aber zur Halterung der Scheiben zusätzlich mit Glasleisten od. dgl. bestückt werden müssen, was zu einem erhöhten Herstellungs- und Verglasungsaufwand bei der Fensterfertigung führt.Profiles made of thermoplastic materials, preferably extruded polyvinyl chloride (PVC) profiles, are used to manufacture windows, doors, frames and the like. Like components generally connected by butt welding, for which there are already single or multi-head welding devices of different designs. In these devices, two profiles are welded to one another per welding head, by pressing the profiles clamped in the profile clamping units on the end face against a heating mirror inserted between the profile ends until they melt, and then pressing the plasticized profile ends together after removing the heating mirror, so that the profiles are pressed together Depending on the number of welding heads, have one or more welding connections made at the same time. Since the known, essentially rectangular heating mirrors, which are inserted normally to the clamping plane between the profile ends, must lie flat against their end faces to melt the profile ends, the profiles must not have or include any protruding parts, so that from the start welding two profiles with already in the provided longitudinal groove of the disc or the like, which would prevent the heating mirror from entering between the profile ends, is impossible.The frame profiles must therefore form open grooves that allow the discs to be inserted after welding the frames, but to hold the Panels must also be equipped with glazing beads or the like, which leads to increased manufacturing and glazing costs in window production.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Schweißvorrichtung der eingangs geschilderten Art zu schaffen, die mit einfachsten Mitteln eine wesentliche Rationalisierung der Fensterfertigung od. dgl. erlaubt.The invention is therefore based on the object of eliminating these deficiencies and of creating a welding device of the type described at the outset, which allows a substantial rationalization of window production or the like with the simplest means.

Die Erfindung löst diese Aufgabe dadurch, daß der Heizspiegel an einem parallel zur Aufspannebene in Gehrungsrichtung beweglichen Spiegelhalter angeordnet und im Vorderkantenbereich mit einer der Lage und Form nach an die Profilnut angepaßten Ausklinkung versehen ist. Dieser Heizspiegel gewährleistet das ordnungsgemäße Stumpfschweißen von Kunststoffprofilen ohne deren Längsnut abzudecken, so daß Profile verschweißt werden können, die bereits vor dem Schweißvorgang mit einer Glasscheibe od. dgl. bestückt wurden. Der parallel zur Scheibenebene zwischen die Profilenden eingeführte Heizspiegel schiebt sich im Schweißbereich mit seiner Ausklinkung über den Scheibenrand, wodurch der die Scheibe umgreifende Heizspiegel das gegenseitige Verschieben der Profile und damit den Anschmelzvorgang trotz der eingelegten Scheibe unbehindert läßt. Diese einfache Maßnahme erlaubt es nun, gleichzeitig mit dem Zusammenschweißen der Profile zu einem Fensterrahmen od. dgl. die zugehörige Scheibe einzusetzen, so daß ohne nachträgliche Verglasungsarbeiten oder die Notwendigkeit zusätzlicher Glasleisten schnell und sauber fertig verglaste Fenster od. dgl. entstehen.The invention solves this problem in that the heating mirror is arranged on a mirror holder which is movable parallel to the mounting plane in the miter direction and is provided in the leading edge region with a notch adapted to the profile groove in terms of position and shape. This heating mirror ensures the proper butt welding of plastic profiles without covering their longitudinal groove, so that profiles can be welded which have already been fitted with a glass pane or the like before the welding process. The heating mirror inserted parallel to the pane level between the profile ends pushes itself in the welding area with its notch over the edge of the pane, so that the heating mirror encompassing the pane allows the profiles to move and thus the melting process unimpeded despite the inserted pane. This simple measure now allows the associated pane to be used simultaneously with the welding of the profiles to form a window frame or the like, so that finished glazed windows or the like are produced quickly and cleanly without subsequent glazing work or the need for additional glazing beads.

Weist dabei der Heizspiegel eine auf zwei nebeneinanderliegende Profile äbgestimmte Größe auf, läßt sich dieser Spiegel einerseits zum Verschweißen glasbestückter Profile und anderseits durch ein entsprechend weites Einschieben zwischen die Profilenden auch in üblicher Form zum Schweißen unbestückter bzw. ungenuteter Profile verwenden. Weiters besteht die Möglichkeit, mit ein und demselben Heizspiegel gleichzeitig zwei Schweißverbindungen herzustellen und nebeneinander sowohl die Profile eines Flügelrahmens mit eingesetzter Scheibe als auch die scheibenlosen Profile eines Stockrahmens zu schweißen. Selbstverständlich kann der Heizspiegel außerdem, um die Schweißvorrichtung an unterschiedliche Profile anzupassen, lös- und austauschbar am Spiegelhalter befestigt sein, so daß durch entsprechende Wahl des Heizspiegels die für das jeweilige Profil geeignete Ausklinkung vorbereitet istIf the heating mirror has a size matched to two adjacent profiles, this mirror can be used on the one hand for welding glass-tipped profiles and on the other hand by a correspondingly wide insertion between the profile ends in the usual form for welding untipped or un-grooved profiles. It is also possible to use the same heating mirror to make two welded connections at the same time and to weld both the profiles of a casement with an inserted pane and the paneless profiles of a stick frame next to each other. Of course, in order to adapt the welding device to different profiles, the heating mirror can also be detachably and interchangeably attached to the mirror holder, so that the notch suitable for the respective profile is prepared by appropriate selection of the heating mirror

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigen Fig. 1 eine erfindungsgemäße Schweißvorrichtung in schematischer Draufsicht und Fig. 2 den Heizspiegel dieser Schweißvonichtung in Seitenansicht.In the drawing, the subject matter of the invention is shown, for example, that FIG. 1 shows a welding device according to the invention in a schematic plan view and FIG. 2 shows the heating mirror of this welding device in a side view.

Um Kunststoffprofile (1), die Längsnuten (2) zur Aufnahme einer Glasscheibe (3) bilden, auch dann miteinander Stumpfschweißen zu können, wenn die Glasscheibe (3) bereits in die Längsnuten (2) eingesetzt ist, gibt es eine mit wenigstens einem Schweißkopf (4) ausgerüstete Schweißvorrichtung, welcher Schweißkopf (4) zwei relativ zueinander verschiebbare Profilaufspanneinheiten (5) zum Festklemmen und Längsbewegen der Profile (1) und einen zwischen die auf Gehrung geschnittenen Profilenden einführbaren Heizspiegel (6) aufweist. Der Heizspiegel (6) ist dabei vorzugsweise austauschbar an einem Spiegelhalter (7) eines in Gehrungsrichtung verfahrbaren Schlittens (8) od. dgl. befestigt und mit einer in Lage und Form an die Längsnut (2) der Profile (1) angepaßten Ausklinkung (9) versehen, so daß die Ausklinkung (9) des Heizspiegels (6) bei dessen Einführen zwischen die Enden der zu verschweißenden Profile (1) auf den Scheibenrand aufschiebbar ist und der die Scheibe (3) mit der Ausklinkung (9) umgreifende Heizspiegel (6) ein Relativverschieben der Scheibe (3) bzw. der Profile (1) im Zuge des Anschmelzvorganges unbehindert läßt.In order to be able to butt weld plastic profiles (1), which form longitudinal grooves (2) for receiving a glass pane (3), even when the glass pane (3) is already inserted into the longitudinal grooves (2), there is one with at least one welding head (4) equipped welding device, the welding head (4) has two relatively movable profile clamping units (5) for clamping and longitudinal movement of the profiles (1) and a heating mirror (6) that can be inserted between the mitred profile ends. The heating mirror (6) is preferably exchangeably attached to a mirror holder (7) of a slide (8) or the like which can be moved in the miter direction and has a notch (9) adapted in position and shape to the longitudinal groove (2) of the profiles (1) ) so that the notch (9) of the heating mirror (6) can be pushed onto the edge of the pane when it is inserted between the ends of the profiles (1) to be welded and the heating mirror (6) encompassing the pane (3) with the notch (9) ) a relative displacement of the disc (3) or the profiles (1) in the course of the melting process leaves unimpeded.

Wird der Heizspiegel (6) in seiner Größe auf zwei nebeneinander angeordnete Profile abgestimmt, wie das für ein Flügelrahmenprofil (1) und ein Stockrahmenprofil (10) angedeutet ist, kann dieser Heizspiegel (6) je nach Vorschubweite sowohl zum Verschweißen glasbestückter Profile (1) als auch unbestückter Profile (10) und außerdem zum gleichzeitigen Verschweißen von Flügel- und Stockrahmenprofilen verwendet werden. -2-If the size of the heating mirror (6) is matched to two profiles arranged side by side, as indicated for a casement frame profile (1) and a stick frame profile (10), this heating mirror (6) can be used for welding glass-tipped profiles (1) depending on the feed width. as well as unequipped profiles (10) and can also be used for the simultaneous welding of sash and stick frame profiles. -2-
