Description

Gerät zum Erzeugen eines Heißluftstromes für das Verschweißen von thermoplastischen Kunststoffen Für die Erweichung von thermoplastischen Kunststoffen, insbesondere Polyvinylchlorid, hat man gas- oder elektrisch beheizte Vorrichtungen oder von einer Löflampe od. dgl. erzeugte Heißluftströme benutzt. Dabei ist der Benutzer niemals sicher, daß die erforderliche Temperatur vorhanden ist. Im Gegenteil tritt erfahrungsgemäß oft ein Überhitzen des Kunststoffes ein. Dabei ist zu berücksichtigen, daß der Kunststoff in überwiegendem Maße bei Bauarbeiten Anwendung findet, bei denen die Erwärmung an der Baustelle selbst stattfinden muß. Hier muß man1 also das Gerät zur Erzeugung der heißen Luft, z.B. die Lötlampe, an Ort und Stelle mitnehmen, so daß infolgedessen eine rein nach Gefühl gehende Erwärmung des thermoplastischen Kunststoffes stattfindet.Device for generating a stream of hot air for welding thermoplastics For the softening of thermoplastics, in particular polyvinyl chloride, one has gas or electrically heated devices or hot air streams generated by a torch or the like. Here is the Users never make sure that the required temperature is available. On the contrary Experience has shown that the plastic often overheats. It must be taken into account that the plastic is predominantly used in construction work where the heating must take place at the construction site itself. So here you have to1 the device to generate the hot air, e.g. take the blowtorch with you on the spot, see above that as a result a purely sensual heating of the thermoplastic Plastic takes place.

Demgegenüber richtet sich das Ziel der Erfindung darauf, ein Gerät zu schaffen, das eine genaue Einregelung der auf den Kunststoff wirkenden Wärme ermöglicht und gleichzeitig so beschaffen ist, daß es unabhängig von Gas- und elektrischen Leitungen an die Verbindungsstelle herangeführt werden kann. Insbesondere handelt es sich dabei darum, daß für diese Zwecke die bekannten Geräte, wie Lötlampen, Kocher od. dgl., verwendbar gemacht werden, und zwar so, daß auch mit bereits vorhandenen derartigen Geräten gearbeitet werden kann. In contrast, the aim of the invention is directed to a device to create a precise regulation of the heat acting on the plastic made possible and at the same time such that it is independent of gas and electric Lines can be brought to the connection point. In particular, acts It is a matter of the fact that for this purpose the known devices, such as blowtorches, cookers Od. Like., Can be made usable, in such a way that also with existing ones such devices can be worked.

Dieses Ziel wird dadurch erreicht, daß im Anschluß an eine heißgehende Wärmequelle ein Rohr derart angeordnet ist, daß die in das Rohr gelangende Heiß luft mit Frischluft sich mischt und heim Rohraustritt eine gewünschte Wärme aufwelist. This goal is achieved by following a hot going Heat source a tube is arranged so that the getting into the tube hot air mixes with fresh air and generates the desired heat at the pipe outlet.

Zweckmäßig besteht das Rohr aus mehreren teleskopartigen, ineinandersteckenden und auszieh- haaren Teilen, wodurch die genaueste Ein regelung des aus dem Rohr austretenden Heißluftstromes ermöglicht ist. The tube expediently consists of several telescopic, nested ones and pull-out hair parts, whereby the most precise regulation of the hot air flow emerging from the pipe is made possible.

Als Wärmequelle findet nun ein bekanntes Gerät, wie z. B. eine Lötlampe, ein mit flüssigem Brennstoff betriebener Kocher od. dgl., Venvendung, wobei das Rohr abnehmbar mit der Litlampe od. dgl. verbunden ist. A well-known device, such as B. a blowtorch, a liquid fuel stove or the like., Use, wherein the The tube is detachably connected to the lit lamp or the like.

Auf diese Weise braucht nicht erst ein neues Gerät entwickelt zu werden, sondern man kann die bekannten Geräte verwenden und dabei sogar bereits vorhandene Geräte benutzen, weil es nur erförderlich ist, auf diese Geräte das Rohr aufzustecken. This way, a new device doesn't need to be developed first but you can use the known devices and even use them already Use existing devices because it is only necessary to use the pipe on these devices to put on.

Zur näheren Erläuterung der Erfindung dienen die Abbildungen in der Zeichnung, und zwar zeigt Abb. 1 im senkrechten Querschnitt eine Ausführungsform, Abb. 2 ebenfalls ilm senkrechten Querschnitt eine zweite Ausführungsform, Abb. 3 in Seitenansicht eine weitere Ausführungsform, Abb. 4 noch eine Ausführungsform im senkrechten Querschnitt, Abb. 5 ein Schaubild der in Abb. 4 dargestellten. The illustrations in FIG Drawing, namely Fig. 1 shows in vertical cross section an embodiment, Fig. 2 shows a second embodiment, also in a vertical cross-section, Fig. 3 in side view another embodiment, Fig. 4 still another embodiment in vertical cross section, Fig. 5 is a diagram of the one shown in Fig. 4.

Ausführungsform.Embodiment.

Nlit Bezug auf Abb. I ist die Wärmequelle eine elektrisch beheizte Platte I0, wie sie beil elektrischen Kochern im allgemeinen üblich ist. Auf diese Platte ist mit den Füßen 11 ein senkrechtes Rohr aufgesetzt, das aus zwei teleskopartig ineinander verschiebbaren Teilen 12 und 13 besteht. With reference to Fig. I, the heat source is an electrically heated one Plate I0, as is commonly used in electric cookers. To this Plate is placed with the feet 11 a vertical tube, which consists of two telescopic parts 12 and 13 which can be slid into one another.

Diese Teile werden durch. eine Schraube I4, die durch einen Längsschlitz des Rohres I2 hindurchgeht, in der gewünschten Stellung gesichert. Die heiße Luft, welche die Platte 10 entwickelt, strömt nach oben in das Rohr hinein und vermischt sich dabei mit der in das Rohr angesaugten Frischluft.These parts are through. a screw I4 passing through a longitudinal slot of the pipe I2 passes through, secured in the desired position. The hot air which develops the plate 10 flows up into the tube and mixes with the fresh air sucked into the pipe.

Je nachdem nun das Rohr mehr oder weniger langgehalten wird, tritt der Heiß luftstrom am oberen Ende des Rohres mit einer gewünschten Temperatur aus. Diese Temperatur wird so geregelt, wie das für die Erweichung für das Schweißen des Kunststoffes erforderlich ist.Depending on whether the pipe is held more or less long, occurs the hot air flow from the upper end of the tube at a desired temperature. This temperature is regulated in the same way as that for softening for welding of the plastic is required.

Bei der Ausführung nach Abb. 2 hat eine durch aus bekannte Lötlampe 15 Verwendung gefunden, bei der die Stichflamme durch das lotrecht stehende Rohr 16 nach oben austritt. Auf diese Lampe ist mittels der Füße 17 das Rohr 12, I3 aufgesteckt. In the embodiment according to Fig. 2 has a blowtorch known from 15 found use in which the jet flame through the perpendicular pipe 16 exits upwards. The tube 12, I3 is pushed onto this lamp by means of the feet 17.

Hier ist also ersichtlich, daß man eine bereits vorhandene Lötlampe nehmen und durch Aufsetzen des Rohres 12, 13 in ein Gerät umwandeln kann, bei welchem der Heißluftstrom in gewünschtem Maße geregelt wird.So here you can see that you have an existing blowtorch take and can convert by placing the tube 12, 13 in a device in which the hot air flow is regulated to the desired extent.

Bei der Ausführung nach Abb. 3 handelt es sich wiederum um eine bekannte Lötlampe I8, bei der das Flammrohr 19 waagerecht liegt. Auch hier ist mittels der Streben 20 das nunmehr waagerecht liegende Rohr 12, 13 mit der Lötlampe verbunden. The embodiment according to Fig. 3 is again a known one Blowtorch I8, in which the flame tube 19 lies horizontally. Again, by means of the Struts 20, the now horizontally lying tube 12, 13 connected to the blowtorch.

Auch. hier kann eine gewöhnliche, unter Umständen bereits vorhandene Lötlmnpe ohne weiteres in d.as Gerät gemäß der Erfindung umgewandelt werden.Even. an ordinary, possibly already existing one can be used here Soldering tube can easily be converted into the device according to the invention.

Bei der in Abb. 4 und 5 dargestellten Ausführung ist ein üblicher, m:it flüssigem Brennstoff betriebener Kocher 21 verwendet, über den. ein zylindrischer Hohlkörper22 mit Füßen 23 gestülpt ist. Die Wandung des Körpers ist mit Luftdurchlässen 24 ausgerüstet, die gegebenenfalls durch Schieber od. dgl. zugesperrt werden können. Die von dem Kocher, der i'n seiner Aus.führung durch aus bekannt und üblich ist, erzeugte Flamme entwickelt heiße Gase, die sich in dem Hohlkörper 22 mit Frischluft mischen und am oberen Ende des Körpers z2 eine verhältnismäßig große Erwärmungsfläche für die aus thermoplastischem Kunststoff bestehenden Werkstücke bilden. Für diese Werkstücke sind, soweit sie rohrförmig od. dgl. gestaltet sind, an dem Kärper 22 Auflager 25 und, soweit sie plattenförmig od. dgl. gestaltet sind, Auflager 26 angebracht. In the embodiment shown in Fig. 4 and 5, a common, With liquid fuel operated digester 21 used over the. a cylindrical one Hollow body 22 with feet 23 is turned inside out. The wall of the body is provided with air passages 24 equipped, which, if necessary, can be locked by slides or the like. That of the cooker, which in its execution is known and common, The flame generated develops hot gases, which are in the hollow body 22 with fresh air mix and at the upper end of the body z2 a relatively large heating surface for the workpieces made of thermoplastic material.
