Description

Die Erfindung betrifft eine Vorrichtung zum Verschweißen eines aus thermoplastischem Kunststoffmaterial bestehenden Überzuges von plattenförmigen Körpern, insbesondere Wandbelagplatten, mit einer höhenbeweglichen isolierenden Halterungsplatte, an der leisten artig ausgebildete Elektroden befestigt sind und die auf das auf einer feststehenden, die Gegenelektrode bildenden Unterlage aufliegende tZberzugsmaterial absenkbar ist. The invention relates to a device for welding a thermoplastic plastic material existing coating of plate-shaped bodies, in particular wall covering panels with a height-adjustable insulating mounting panel, are attached to the bars-like electrodes and on the Covering material resting on a stationary base forming the counter electrode is lowerable.

Es gibt einen Wandbelag, der aus plattenartigen Einzelelementen zusammengesetzt ist, die nebeneinanderliegend an der Wand u. dgl. befestigt sind. Diese Belagplatten bestehen aus einem Tragkörper, beispieIsweise in Gestalt einer HoIzplatte, auf dem eine Polsterschicht, etwa aW Schaumgummi, aufgelegt ist, die von einem das Ganze umhüllenden Überzug aus thermoplastischem Kunststoffmaterial überdeckt wird. Das Überzugsmaterial wird bei der Herstellung dieser Platten längs der Berandung verschweißt, so daß sich ein allseitig geschlossenes, stabiles Gebilde ergibt. Zum Verschweißen finden üblicherweise Elektroden Verwendung die, entsprechend der Schweißnaht, leistenartig ausgebildet sind und an der erwähnten Halterungsplatte sitzen. There is a wall covering made up of individual panel-like elements which are attached to the wall and the like next to each other. These covering plates consist of a supporting body, for example in the form of a wooden plate, on which a layer of cushioning, such as foam rubber, is placed on top of the whole enveloping coating made of thermoplastic material is covered. That Covering material is welded along the edge during the production of these plates, so that a stable structure that is closed on all sides results. For welding Usually electrodes are used which, according to the weld seam, are strip-like are formed and sit on the bracket plate mentioned.

Eine Schwierigkeit bei der Herstellung dieser Platten, die übrigens auch bei der Befestigung von Überzügen aus solchem thermoplastischem Material auf Tischplatten, Möbelflächen u. dgl. auftritt, besteht darin, daß das Überzugsmaterial während des Verschweißens allseitig straff gespannt gehalten werden muß, damit sich ein straffer, faltenloser Sitz des Überzugs auf dem Tragkörper oder der zu überziehenden Fläche ergibt. Wohl ist es möglich, das Material beispielsweise mittels Zangen bis zu einem gewissen Grade während des Verschweißens von Hand straffzuhalten oder aber den -Überzug vor dem Verschweißen zu heften, doch sind diese Verfahren zum einen umständlich, zum anderen liefern sie insbesondere bei größeren Flächen keine befriedigenden Ergebnisse. One difficulty in making these panels, by the way also when attaching coatings made of such thermoplastic material Table tops, furniture surfaces and the like occurs, consists in the fact that the covering material must be kept taut on all sides during welding so that a tight, wrinkle-free fit of the cover on the support body or the cover to be covered Area results. It is possible, for example, to cut the material up using pliers or to hold it taut to a certain extent by hand during welding to tack the coating before welding, but these methods are on the one hand awkward, on the other hand, they do not provide satisfactory results, especially for larger areas Results.

Ziel der Erfindung ist es, hier abzuhelfen und eine Vorrichtung der eingangs genannten Art zu schaffen, die gleichzeitig beim Verschweißen selbsttätig die erforderliche Straffung des Überzugsmaterials bewirkt und somit ohne zusätzliche Handgriffe eine einwandfreie Anordnung des Überzuges auf dem Tragkörper oder allgemein der zu überziehenden fläche gewährleistet. Dieses Ziel wird gemäß der Erfindung dadurch erreicht, daß die Halterungsplatte an zumindest zwei gegenüberliegenden Seiten außerhalb der jeweils benachbarten Elektroden angeordnete, verschwenkbar angelenkte Spannleisten trägt, die an ihrer mit dem Überzugsmaterial in Eingriff kommenen Kante Zähne aufweisen und beim Absenken der Halterungsplatte gegen die Unterlage unter gleichzeitigem Spannen des Überzugsmaterials auf der Unterlage nach außen spreizbar sind. The aim of the invention is to remedy this and a device of To create the type mentioned at the beginning, which at the same time automatically when welding causes the required tightening of the cover material and thus without additional Handles a proper arrangement of the coating on the support body or in general the area to be covered guaranteed. This aim is achieved according to the invention achieved in that the mounting plate on at least two opposite Sides arranged outside of the respectively adjacent electrodes, pivotable wears hinged clamping bars, which at their with the cover material in engagement coming edge have teeth and when lowering the mounting plate against the Underlay while simultaneously tensioning the cover material on the underlay are expandable on the outside.

Beim Niedergehen der die Elektroden tragenden Halterungsplatte greifen die Spannleisten mit ihren Zähnen zunächst auf das auf der Unterlage liegende Überzugsmaterial ein, wobei die Zähne in das Material etwas eindringen. Wird die Halterungsplatte noch weiter nach unten gedrückt, so werden die Spannleisten jeweils nach außen gespreizt, wodurch auf das Überzugsmaterial im Sinne der Straffung wirkende Zugkräfte ausgeübt werden. Kommt schließlich im Verlaufe der weiteren Absenkbewegung der Halterungsplatte das Überzugsmaterial mit den Elektroden in Berührung, worauf die Verschweißung einsetzt, so wird hierbei das Material von den Spannleisten straff gehalten, so daß der Überzug nach Fertigstellung der Schweißnaht in dem gestrafften Zustand auf dem zugeordneten Tragkörper bzw. der zu überziehenden Fläche fixiert ist. Da die Straffung während des Niedergehens der Elektroden auf die den Überzug tragende Unterlage völlig selbsttätig durch die Spannleisten erfolgt, sind keinerlei zusätzliche Handgriffe erforderlich. Darüber hinaus zeichnet sich die neue Vorrichtung durch einen sehr einfachen und wirkungsvollen Aufbau aus. When going down, grasp the mounting plate carrying the electrodes the clamping bars with their teeth first on the coating material lying on the base a, whereby the teeth penetrate the material somewhat. Will be the mounting plate pressed even further down, the clamping bars are each spread outwards, whereby tensile forces acting in the sense of tightening are exerted on the covering material will. Finally comes in the course of the further lowering movement of the mounting plate the coating material with the electrodes in contact, whereupon the welding starts, so here the material is held taut by the clamping bars, so that the coating after completion of the weld in the tightened state on the associated Support body or the surface to be coated is fixed. Because the tightening during the lowering of the electrodes on the base carrying the coating completely automatically takes place through the clamping bars, no additional hand movements are required. In addition, the new device is characterized by a very simple and effective structure.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt. Es zeigt F i g. 1 eine Vorrichtung gemäß der Neuerung, im axialen Schnitt, in einer Seitenansicht und F i g. 2 die Vorrichtung nach F i g. 1 in einer Untersicht. In the drawing is an embodiment of the subject matter of Invention shown. It shows F i g. 1 a device according to the innovation, in axial section, in a side view and FIG. 2 the device according to FIG. 1 in a soffit.

An einer aus elektrisch isolierendem Material bestehenden Halterungsplatte 1 sind metallische Elektroden 2 angeordnet, die nach Art von Leisten ausgebildet sind. Die Elektroden 2 können in bekannter Weise an eine nicht weiter dargestellte Stromquelle angeschlossen werden, während die Gegenelektrode von einer Unterlage 7 gebildet wird, gegen die die Halterungsplatte 1 mit den Elektroden2 aus einer angehobenen Stellung absenkbar ist, wobei dann längs der Stirnberandung der Elektroden 2 auf der der Unterlage 7 zugewandten Seite eine Verschweißung des bei 6 angedeuteten thermoplastischen tÇberzugsmaterials zustande kommt. On a mounting plate made of electrically insulating material 1 metallic electrodes 2 are arranged, which are designed in the manner of strips are. The electrodes 2 can be connected in a known manner to a not shown Power source can be connected while the counter electrode is supported by a support 7 is formed, against which the mounting plate 1 with the electrodes 2 from a raised position can be lowered, then along the front edge of the electrodes 2, on the side facing the base 7, a weld of the one indicated at 6 thermoplastic cover material comes about.

Außerhalb der Elektroden2 sind an jeweils gegenüberliegenden Seiten der Halterungsplatte 1 (vgl. insbesondere F i g. 2) Spannleisten 4 mittels Scharnieren3 3 angelenkt, die ebenfalls aus einem elektrisch isolierenden Material bestehen. Die Spannleisten 4 tragen auf ihrer der Unterlage 7 zugewandten Kante Zähne 5, die beim Absenken der Halterungsplatte 1 gegen die Unterlage 7 in der aus F i g. 1 ersichtlichen Weise in das auf der Unterlage 7 aufliegende Überzugsmaterial 6 eingreifen können. Die Spannleisten 4 sind jeweils unter einem Winkel gegen die Halterungsplatte angeordnet, der kleiner als 900 ist. Da die Spannleisten 4 darüber hinaus bei abgehobenen Elektroden 2, d. h. in ihrer Ruhestellung, mit ihrer gezahnten Kante über die Stirnfläche der Elektroden 2 vorstehen, werden sie, nachdem die Zähne 5 auf dem Überzugsmaterial 6 aufsitzen und dieses durchdringend auf die Unterlage 7 gelangen, auf der Unterlage 7 nach außen gleitend jeweils nach außen gespreizt. Diese Spreizbewegung ist in F i g. 1 durch zwei Pfeile angedeutet. Sie bewirkt, daß das Überzugsmaterial beim Niedergehen der Halterungsplatte 1 zunächst gestrafft wird, bevor die Elektroden2 mit ihren Stirnflächen das Überzugsmaterial gegen die Unterlage 7, d. h. die Gegenelektrode, drücken können und die Verschweißung erfolgt. Outside the electrodes2 are on opposite sides the mounting plate 1 (cf. in particular FIG. 2) clamping strips 4 by means of hinges 3 3 hinged, which also consist of an electrically insulating material. The clamping strips 4 have teeth 5 on their edge facing the base 7, which when lowering the mounting plate 1 against the base 7 in the form shown in FIG. 1 can be seen Way can intervene in the coating material 6 lying on the base 7. The clamping bars 4 are each arranged at an angle against the mounting plate, that is less than 900. Since the clamping bars 4 also when the electrodes are lifted 2, d. H. in its rest position, with its toothed edge over the face of the Electrodes 2 protrude, they become after the teeth 5 on the coating material 6 and get this penetrating on the pad 7, on the pad 7 slidably spread outwards. This spreading movement is in F i g. 1 indicated by two arrows. It causes the coating material when Going down the mounting plate 1 is first tightened before the electrodes2 with their end faces the coating material against the base 7, d. H. the counter electrode, can press and the welding takes place.

Um die Spannleisten 4, die jeweils paarweise gegenüberliegend angeordnet sind, bei abgehobener Halterungsplatte 1 in der in Fig. 1 dargestellten Ausgangslage zu halten, sind sie zumindest gegenüber der Halterungsplatte 1 durch Federungselemente 9 abgestützt. Eine besonders zweclcmäßige Ausführungsform ergibt sich, wenn als Federungselemente 9 elastische Schaumstoffstückchen verwendet werden, die etwa in der aus F i g. 1 ersichtlichen Weise zwischen die Spannleisten 4 und die Halterungsplatte 1 sowie die benachbarten Elektroden 2 eingefügt sind. To the clamping bars 4, which are each arranged in pairs opposite one another are, with the mounting plate 1 lifted, in the starting position shown in FIG to hold, they are at least opposite the mounting plate 1 by suspension elements 9 supported. A particularly useful embodiment results when as Spring elements 9 elastic foam pieces are used, which are approximately in the one from FIG. 1 visible way between the clamping strips 4 and the mounting plate 1 and the adjacent electrodes 2 are inserted.

Diese Schaumstoffstückchen können sich über die ganze Länge der Spannleisten erstrecken. These pieces of foam can extend over the entire length of the clamping strips extend.

Die Ausbildung der Zähne 5 an den Spannleisten 4 kann in der Weise geschehen, daß in deren freie Stirnflächen metallische Sägeblätter 8 eingesetzt sind. The formation of the teeth 5 on the clamping strips 4 can be in the manner happen that metallic saw blades 8 are used in their free end faces are.

Im übrigen braucht die Unterlage 7 nicht eben zu sein; sie kann ebenso, wie auch die Unterflächen der Elektroden 2, entsprechend den jeweiligen Erfordernissen gewölbt oder sonstwie gestaltet sein. In addition, the base 7 does not need to be flat; she can also, as well as the lower surfaces of the electrodes 2, according to the respective requirements be arched or otherwise designed.
