Description

Zusatzvorrichtung zum Verbinoen von Thermoplastoflien ourch Hei#gasschwei#en Fie Erfindung betrifft einen verbesserten Schwei#kopf zur Vorrichtung nach Patentsnmeldung Z 12 593 X 39a2 zum Verbinden von Thermoplastfolien durch Hei#gasschwei#en. Additional device for connecting thermoplastic films by hot gas welding The invention relates to an improved welding head for the device according to the patent application Z 12 593 X 39a2 for joining thermoplastic foils by hot gas welding.

Im Hauptpatent wurde vorgeschlagen, zum Zweck des Korrosionsschutzes aufgeklebte Thermoplastfol ien, ie stumpf aneinandersto#en, mit einer artgleichen Profillasche zu verbinden. bas geschieht, indem eine selbst@ahrende Vorrichtung die Profillasche mittels Hei#gas und Rollendruck mit den Folien verschweifit. Die je nach Bedarf ausgexiloete profilnase füllt dabei den Querschnitt der Nahtfuge aus.In the main patent it was suggested for the purpose of corrosion protection Glued on thermoplastic foils, ie butt butt against each other, with a similar one To connect profile bracket. bas is done by a self-listening device the profile flap is welded to the foils using hot gas and roller pressure. the Depending on the requirements, the extrusion nose fills the cross-section of the seam the end.

Mit der im @au@tpatent beschriebenen Vorrichtung kann man alleroings nur stumpf geschwei@te Nähte herstellen, wobei £ie DI ; oene, auf dtr oie Schwei@vorrichtung fährt, annähernd mit der jene des Verb n@ungssto#es äbereinstimmen rfiuß.With the device described in @ au @ tpatent one can alleroings only produce butt welded seams, whereby £ ie DI; open, on dtr oie welding device drives, approximately with which those of the verb n @ ungssto # es agree rfiuss.

Zweck der Erfindung ist es, die Vorrichtung auch für andere @ahtformen verwenden zu @omen.The purpose of the invention is to use the device for other seam shapes use to @omen.

@a#ei besteht d e Aufgabe @arin, den Scnwei#kopf für die @esonderneiten anderer @ahtformen umzugestaiten.@ a # ei consists of the task @arine, the little head for the @special things other @ahtformen umzuestaiten.

Erfinöungsgemä# wird das dadurch gelost, indem der Scwwei#-@opf zusätzlich um eine in Fanrtrichtung der Vorrichtung liegende Achse 15 schwenkbar gemacht wird. Der ausschwenkwinkel wird dabei durch eine Gradeinteilung an der Stirnseite des Schwei#kopfes angezeigt. Entsprechend der Form der Schwei#naht mu# auch die Druckrolle eine geeignete Form erhalten. Das bedingt gleichzeitig eine äquivalente Ausbildung der hei#gas-@ 0''. ze @we ckmä#igerweise durch ein in entsprechend ausgebildetes Rohr mit dem He@zaggre@at verbunden wird.According to the invention, this is solved by adding the swine # - @ opf is made pivotable about an axis 15 lying in the fan direction of the device. The swivel angle is determined by a graduation on the face of the Welding head is displayed. The pressure roller must also correspond to the shape of the weld seam get a suitable shape. This also requires an equivalent training the hot # gas- @ 0 ''. ze @we ckmä # sometimes through an appropriately trained Pipe to which He @ zaggre @ at is connected.

Auch ist es möglich, den büsenschlitz durch eine Reile nebeneinanderliegender Einzelöffnungen z@ ersetzen.It is also possible to place the bus slot next to each other through a row Replace single openings z @.

Druckrolle und Hei#gasdüse sind mit wenigen Handgriffen auswechselbar, sie kön@en aber auch in einem auswechselbaren System zusammengefa#t werden. Die Vorrichtung kann entweder auf der Fläche des zu schwei#enden Körpers, oder auf einer besonderen Führungsbahn fahren, wobei in letzteren Fall eine Spannvorrich@ung für das Werkstück damit kombiniert werden kann.The pressure roller and hot gas nozzle can be exchanged in a few simple steps, but they can also be used in an interchangeable one System summarized will. The device can either be placed on the surface of the body to be welded, or drive on a special guideway, whereby in the latter case a tensioning device for the workpiece can be combined with it.

Der Vorteil der Erfindung besteht darin, ga# das Schwei#-Eeriit universeller eingesetzt werden kann. Von besonderer Bedeutung ist, da# das mechanisierte Schwei#en von Kehl-und Ecknähten moglich wird, jedoch könne auch anders geformte Schwei#verbindungen oamit hergestellt werden.The advantage of the invention is that it makes welding more universal can be used. It is of particular importance that mechanized welding of fillet and corner seams is possible, but differently shaped welded joints can also be used oamit be produced.

Das soll anschlie#end an einem Ausführungsbeispiel näher erläutert werden Die Vorrichtung soll daoei zum Schwei#en von Kehlnähten eingesetzt werden. iuach Fig. 1 fährt dabei die Vorrichtung auf einer Fläche, die durch ei£e der zu verschwei#enden Folien gebildet wird. ber Schwei#kopf wir@ mit einer für Kehlnähte geeigneten Druckrolle 2 und mit einer rechtwinklig ausgebildeten Hei#gasdüse (Fig. 2) versehen.This will then be explained in more detail using an exemplary embodiment The device is intended to be used for welding fillet welds. In accordance with FIG. 1, the device moves on a surface which is closed by one of the fusing foils is formed. Above the welding head we @ with one for fillet welds suitable pressure roller 2 and with a right-angled hot gas nozzle (Fig. 2) provided.

Die seitliche Neigung des Schwei#kopfes wird auf den geeigneten ert von 45° eingestellt.The lateral inclination of the welding head is adjusted to the appropriate one set at 45 °.
