Description

Vorrichtung zum stirnseitigen Verschweißen von thermoplastischem Material Die Erfindung bezieht sich auf eine Vorrichtung zum kontinuierlichen Verschweißen von thermoplastischem Material, insbesondere zum stirnseitigen Verbinden von Platten welche z. B. als Innenauskleidung von Behältern Verwendung finden. Das dichte Zusammenschweißen von solchen Platten bietet beton ders große Schwierigkeiten, da die Platten in diesem Fall nur von der einen Seite aus zugänglich sind. Die Schweißung erfolgt in solchen Fällen mittels einer Vorrichtung, welche aus einer Düse ein heißes gasförmiges Medium, z. B. Luft oder Gas, auf die Schweißnaht lenkt, wobei mittels eines Schweißstabes, sogenannte Schweißbagette, die Stirnflächen der zu verbindenden Teile homogen verbunden werden.Device for the welding of thermoplastic material on the end face The invention relates to a device for continuous welding of thermoplastic material, especially for connecting panels to the front which z. B. can be used as the inner lining of containers. The tight welding together concrete from such slabs offers great difficulties, since the slabs in this Case are only accessible from one side. The welding takes place in such Felling by means of a device, which from a nozzle a hot gaseous medium, z. B. air or gas, directs to the weld seam, whereby by means of a welding rod, so-called welding bagette, the end faces of the parts to be connected homogeneously connected will.

Die Kanten der aneinanderstoßenden Platten werden dabei abgeschrägt, und die entstehende keilförmige Nut muß dann durch die Masse der Schweißbagette ausgefüllt werden, wofür je nach der Plattenstärke wiederholt ein oder mehrere Arbeitsgänge erforderlich sind. The edges of the adjoining panels are beveled, and the resulting wedge-shaped groove must then go through the mass of the welded bagette be filled in, for which one or more operations are repeated depending on the panel thickness required are.

Anstatt Bagetten zur Auffüllung der keilförmigen Nut zu verwenden, kann man auch direkt an der den Heißluftstrom erzeugenden Pistole einen Vorratsbehälter für thermoplastisches Material anbringen, in welchem letzteres durch Erwärmen verflüssigt und mittels eines gleichzeitigen mechanischen Druckes vorgeschoben wird, bis es beim Austritt aus dem Behälter in die Bahn des heißen Gasstromes gelangt und sich mit dem Plattenmaterial verbindet. Dieses zähflüssige Material wird dann mittels einer gleichfalls an der Pistole angebrachten Rolle auf der Fugenoberfläche verwalkt. Auf diese Weise ist es aber praktisch nicht möglich, solche Fugen in kontinuierlicher Arbeitsweise vollständig dicht und einwandfrei zu verschließen. Instead of using bagettes to fill in the wedge-shaped groove, you can also place a storage container directly on the gun that generates the hot air flow for thermoplastic material, in which the latter liquefies by heating and is advanced by means of simultaneous mechanical pressure until it when exiting the container gets into the path of the hot gas stream and itself connects to the sheet material. This viscous material is then by means of a roller also attached to the gun on the joint surface. In this way, however, it is practically impossible to make such joints continuously To close completely tightly and properly.

Es ist daher auch schon empfohlen worden, insbesondere aneinanderstoßende Rohre aus thermoplastischem Kunststoff mittels einer Vorrichtung miteinander zu verbinden, welche einen vertikalen, in die Stoßfuge einzuführenden Heizdorn aufweist, der mit einem horizontal angeordneten lamellenförmigen Verstreichorgan zusammenarbeitet, während gleichzeitig erweichtes oder aufgeschmolzenes zusätzliches Schweißmaterial in die Stoßfuge an einer Stelle eingeführt wird, die zwischen Heizdorn und Verstreichorgan liegt. Infolge der Hebelwirkung des Stieles der betreffenden Vorrichtung läßt sich dann das Schweißmaterial per Hand in die Stoßfuge einpressen. Dieses in Art eines Lötkolbens arbeitende Gerät ermöglicht aber nicht das Verschweißen über Kopf, wie es bei der Herstellung großer Auskleidungsflächen in Behältern oft notwendig ist, und außerdem besteht auch die Gefahr einer Zersetzung des zusätzlich in die Stoßfuge eingeführten thermoplastischen Materials infolge Überhitzung, dies speziell bei anhaltendem Arbeitsvorgang, so daß keine Gewähr für eine jeder Beanspruchung gewachsene dauerhafte Schweißverbindung gegeben ist. Demzufolge wäre auch die Endleistung, d. h. die in angemessener Zeit umfangmäßig erzielte Schweiß arbeit, z.B. an Plattenmaterial, viel zu gering und damit unwirtschaftlich. It has therefore already been recommended, especially contiguous Thermoplastic pipes to each other by means of a device connect, which has a vertical heating mandrel to be inserted into the butt joint, which works together with a horizontally arranged lamellar spreading element, while at the same time softened or melted additional welding material is introduced into the butt joint at a point between the heating mandrel and the spreading element lies. As a result of the leverage of the handle of the device in question can then press the welding material into the butt joint by hand. This kind of one The device that works with a soldering iron does not allow welding overhead, as is the case it is often necessary when producing large lining areas in tanks, and besides, there is also the risk of decomposition of the addition in the butt joint imported thermoplastic material as a result of overheating, especially in the case of sustained work process, so that no guarantee for any stress permanent weld connection is given. Accordingly, the final output would also be d. H. the extensive welding work carried out in a reasonable amount of time, e.g. on sheet material, much too low and therefore uneconomical.

Mittels der erfindungsgemäßen Vorrichtung lassen sich diese Nachteile beheben, denn sie ermöglicht eine Injizierung des zusätzlichen geschmolzenen Schweißmaterials, die unter Druck in die Stoßfuge bei gleichzeitiger Erweichung der Plattenstoßflächen erfolgt, so daß eine ganz homogene stirnseitige Verschweißung gewährleistet ist, selbst bei engster Fuge oder stumpfwinkelig aneinanderstoßenden Platten, und zwar ohne jede Abschrägung der betreffenden Kanten. These disadvantages can be eliminated by means of the device according to the invention fix, because it allows the additional molten weld material to be injected, under pressure in the butt joint with simultaneous softening of the board joint surfaces takes place so that a very homogeneous frontal welding is guaranteed, even with the narrowest joint or panels abutting one another at an obtuse angle, namely without any beveling of the relevant edges.

Die neue Vorrichtung besteht aus einer durch die Trennfuge zu führenden Heizlamelle, welche mit einer auf der Fugenobertläche geführten und ebenfalls geheizten Verstreichplatte verbunden ist und zusammenarbeitet. Die Heizlamelle erstreckt sich von der Mittellinie der kufenförmig ausgebildeten horizontalen Verstreichlamelle aus nach unten. In dieser Mittellinie befindet sich außerdem direkt hinter der Vertikallamelle die Öffnung einer Zufuhrleitung für das zusätzliche vorverflüssigte Schweißmaterial, welche ihrerseits mit einem indirekt beheizten Vorratsbehälter und einer Druckgasquelle für ein indifferentes Gas in Verbindung steht. In dem Vorratsbehälter herrscht daher stets eine neutrale, einer Oxydation oder einer sonstigen chemischen Zersetzung entgegenwirkende Atmosphäre, so daß das polymere Kunststoffmaterial sich nicht verändern kann und sich bei der Injizierung in die Stoßfuge gut mit dem Material der zu verschweißenden Platten usw. verbindet. Das Inertgas liefert gleichzeitig die für die Injizierung benötigte Energie. The new device consists of one to be led through the parting line Heating lamella, which are guided and also heated with one that is guided on the joint surface Spreading plate is connected and cooperates. The heating lamella extends from the center line of the runner-shaped horizontal spreading lamella off down. This center line is also located directly behind the vertical slat the opening of a supply line for the additional pre-liquefied welding material, which in turn with an indirectly heated storage container and a pressurized gas source for an inert gas is in connection. In the reservoir there is therefore always a neutral, an oxidation or some other chemical decomposition counteracting atmosphere, so that the polymeric plastic material does not change can and when injected into the butt joint works well with the material to be welded Plates, etc. connects. The inert gas also supplies that for the injection required energy.

Ein Ausführungsbeispiel der Vorrichtung ist in der Zeichnung dargestellt, und zwar zeigt Fig. 1 die Vorrichtung in der Gebrauchsstellung im Längsschnitt und Fig. 2 ein Detail der Vorrichtung (Schweißlamelle) in perspektivischer Ansicht. An embodiment of the device is shown in the drawing, namely Fig. 1 shows the device in the position of use in longitudinal section and 2 shows a detail of the device (welding lamella) in a perspective view.

Die Vorrichtung weist einen mit einem Griff versehenen Behälter 2 auf, welcher als Schmelzkammer dient. Dieser Behälter 2 ist mit einem Heizelement 3 versehen, welches zum Erhitzen des Behälterinhaltes dient. Der Behälter 1 weist einen Einfüllstutzen 4 auf, welcher durch einen Schraubendeckel 5 verschließbar ist. Durch eine Leitung 6 mit Drosselhahn 7 steht der Behälter 2 mit einer nicht gezeichneten Druckgasquelle in Verbindung. The device has a container 2 provided with a handle on, which serves as a melting chamber. This container 2 is provided with a heating element 3 provided, which is used to heat the container contents. The container 1 has a filler neck 4, which can be closed by a screw cap 5 is. Through a line 6 with a throttle valve 7, the container 2 is not connected to one Drawn compressed gas source in connection.

Mit 8 ist ein Lamellenträger bezeichnet, welcher am Behälter 2 befestigt ist und eine horizontale kufenförmige Lamelle 9 trägt. In der Mitte der horizontalen Lamelle 9 ist eine vertikale Lamelle 10 befestigt, wobei in der Verlängerung der Schnittlinie 11 der beiden Lamellen 9 und 10 die Mündung einer Ausflußleitung 12 des Behälters 2 liegt. 8 with a lamella carrier is designated, which is attached to the container 2 and a horizontal runner-shaped lamella 9 carries. In the middle of the horizontal Slat 9 is a vertical slat 10 attached, wherein in the extension of Section line 11 of the two lamellas 9 and 10 the mouth of an outflow line 12 of the container 2 lies.

Im Gebrauch wird die Vorrichtung über die zu verschweißende Naht 14 so geführt, daß sich die vertikale Lamelle 10 in die noch offene Naht 14 erstreckt. Diese Lamelle 10 wird durch das Heizelement 3 erhitzt, so daß die zu verbindenden Stirnflächen dureh die Lamelle erwärmt werden. Gleichzeitig wird das in den Behälter 2 eingefüllte, z. B. körnige oder pulverisierte Schweißmaterial 15 ebenfalls erhitzt, aber indirekt, so daß dasselbe durch die Leitung 12 der Schweißstelle zufließt, wobei der Zufluß des Schweißmaterials durch die Einleitung eines neutralen Druckgases, z. B. Stickstoff, in den Behälter 2 gefördert wird. Das Schweißmaterial gelangt unter dem Druck des indifferenten Gases direkt hinter der Vertikallamelle in die noch offene Schweißnaht und füllt diese in Verbindung mit dem verflüssigten Material der Fugenwände homogen aus. Durch Druckveränderung kann die Dichte der Füllung variiert werden, und durch die Änderung der Temperatur der Lamellen können die verschiedensten thermoplastischen Massen geschweißt werden. In use, the device is over the seam to be welded 14 guided so that the vertical lamella 10 extends into the seam 14 that is still open. This lamella 10 is heated by the heating element 3, so that the to be connected Front surfaces can be heated by the lamella. At the same time it is in the container 2 filled, z. B. granular or powdered welding material 15 is also heated, but indirectly, so that the same flows through the line 12 to the welding point, the inflow of the welding material through the introduction of a neutral compressed gas, z. B. nitrogen, is conveyed into the container 2. The welding material arrives under the pressure of the indifferent gas directly behind the vertical lamella in the still open weld seam and fills it in connection with the liquefied material the joint walls are homogeneous. The density of the filling can be varied by changing the pressure be, and by changing the temperature of the lamellas can be the most diverse thermoplastic masses are welded.

Die vertikale Heizlamelle kann der Dicke der zu verschweißenden Kunststoffplatten angepaßt werden; zu diesem Zweck ist das Heizelement auswechselbar in der Vorrichtung angeordnet. The vertical heating lamella can match the thickness of the plastic sheets to be welded be adjusted; for this purpose the heating element is replaceable in the device arranged.

Das zur Verwendung gelangende Schweißmaterial besteht zweckmäßigerweise aus dem gleichen Werkstoff, aus welchem die zu verbindenden Kunststoffplatten bestehen. The welding material used is expediently made made of the same material from which the plastic sheets to be joined are made.
