Description

Beschreibung Industrieschweißanlage Description of industrial welding plant
Die Erfindung betrifft eine Industrieschweißanlage mit einem Werkzeugtisch, der wenigstens eine Werkzeugaufnahme zur Fixierung von zu schweißenden Werkstücken umfasst.The invention relates to an industrial welding machine with a tool table, which comprises at least one tool holder for fixing workpieces to be welded.
Industrieschweißanlagen, die insbesondere zur Schweißung thermo- plastischer Kunststoffteile vorgesehen sind, sind allgemein bekannt. Bekannt sind hierfür insbesondere Heizelementschweißanlagen und Ultraschallschweißanlagen. Derartige Schweißanlagen sind insbesondere für die industrielle Schweißung thermoplastischer Kunststoffteile, insbesondere Kraftstoffbehälter, für die Automobilindustrie geeignet. Bei den be- kannten Schweißanlagen ist jeweils ein Werkzeugtisch vorgesehen, der linear- oder drehbeweglich angeordnet ist und wenigstens eine Werkzeugaufnahme umfasst. Die Werkzeugaufnahme dient zur Fixierung der zu schweißenden Kunststoffteile. Das jeweilige Werkzeug ist insbesondere als Spannwerkzeug ausgeführt. Sobald verschiedene Werkstücke auf der Schweißanlage geschweißt werden müssen, muss das jeweilige Spannwerkzeug demontiert und ein entsprechend neues Spannwerkzeug montiert werden. Die nichtbenötigten Spannwerkzeuge werden separat gelagert.Industrial welding systems, which are intended in particular for welding thermoplastic plastic parts, are generally known. For this purpose, in particular heating element welding systems and ultrasonic welding systems are known. Such welding systems are particularly suitable for the industrial welding of thermoplastic plastic parts, in particular fuel tank, for the automotive industry. In the known welding systems, a tool table is provided in each case, which is arranged linearly or rotatably movable and comprises at least one tool holder. The tool holder serves to fix the plastic parts to be welded. The respective tool is designed in particular as a clamping tool. As soon as different workpieces have to be welded on the welding machine, the respective clamping tool must be dismantled and a new clamping tool must be mounted. The unneeded clamping tools are stored separately.
Aufgabe der Erfindung ist es, eine Industrieschweißanlage der eingangs genannten Art zu schaffen, die optimierte Arbeitsvorgänge ermöglicht.The object of the invention is to provide an industrial welding plant of the type mentioned, which allows optimized operations.
Diese Aufgabe wird dadurch gelöst, dass die Werkzeugaufnahme an einem Drehrahmen angeordnet ist, der um eine zu einer Tischgrundflä- che des Werkzeugtisches parallele Drehachse drehbeweglich gelagert ist. Vorzugsweise ist die Tischgrundfläche horizontal ausgerichtet. Die Drehachse ist somit ebenfalls vorzugsweise horizontal verlaufend aus- geführt. Der Werkzeugtisch ist vorzugsweise beweglich angeordnet und weist wenigstens zwei unterschiedliche Werkzeugaufnahmen auf, um die gleichzeitige Fixierung von wenigstens zwei Werkstücken zu ermöglichen. Die bewegliche Anordnung des Werkzeugtisches ermöglicht die wahlweise Zuordnung jeweils eines Werkstückes zu der entsprechenden Schweißstelle der Industrieschweißanlage. Die erfindungsgemäße Lösung eignet sich insbesondere für Heizelementschweißanlagen oder für Reibschweißanlagen, ist in gleicher Weise aber auch für Ultraschallschweißanlagen einsetzbar. Der Werkzeugtisch ist vorzugsweise line- arbeweglich und/oder um eine vertikale Hochachse drehbeweglich ausgeführt. Der Drehrahmen kann auf einer Seite mit einer entsprechenden Werkzeugaufnahme und auf seiner gegenüberliegenden Seite mit einem Gegengewicht versehen sein. Alternativ ist es möglich, bei dem Drehrahmen auf beiden einander gegenüberliegenden Seiten jeweils eine Werkzeugaufnahme vorzusehen, so dass der Drehrahmen als Wechseloder Wendewerkzeug dienen kann. Die Drehbeweglichkeit des Drehrahmens und damit auch der wenigstens einen Werkzeugaufnahme ermöglicht eine optimierte Zustellung des jeweiligen Werkzeuges zu dem entsprechenden Schweißelement, wobei die Stellung des Drehrahmens vorzugsweise während eines Schweißvorganges verändert werden kann. Hierdurch ist es möglich, auch komplizierte Schweißkonturen durch geeignete Verdrehung des Drehrahmens einerseits und entsprechende Beweglichkeit des Schweißelements andererseits durchzuführen.This object is achieved in that the tool holder is arranged on a rotating frame, which is rotatably mounted about an axis parallel to a Tischgrundflä- surface of the tool table axis of rotation. Preferably, the table base is aligned horizontally. The axis of rotation is thus likewise preferably horizontal. guided. The tool table is preferably arranged to be movable and has at least two different tool holders in order to allow the simultaneous fixing of at least two workpieces. The movable arrangement of the tool table allows the optional assignment of a respective workpiece to the corresponding weld of the industrial welding machine. The solution according to the invention is particularly suitable for heating element welding systems or for friction welding systems, but can also be used in the same way for ultrasonic welding systems. The tool table is preferably linearly movable and / or rotatable about a vertical vertical axis. The rotating frame can be provided on one side with a corresponding tool holder and on its opposite side with a counterweight. Alternatively, it is possible to provide a tool holder in each case on the two opposite sides of the rotary frame, so that the rotary frame can serve as a change or turning tool. The rotational mobility of the rotating frame and thus also the at least one tool holder allows optimized delivery of the respective tool to the corresponding welding element, wherein the position of the rotating frame can be preferably changed during a welding operation. This makes it possible to perform complicated welding contours by suitable rotation of the rotating frame on the one hand and corresponding mobility of the welding element on the other.
In Ausgestaltung der Erfindung ist dem Drehrahmen eine Antriebseinrichtung zugeordnet, die eine Drehbewegung des Drehrahmens bewirkt. Dadurch ist eine gesteuerte Verdrehung des Drehrahmens ermöglicht.
