Description
Beim selbsttätigen Schweißgerät wird von der Rolle geschweißt. " Auf- dieser ist der Schweißdraht aufgewickelt und wird durch ein Transportwerk abgewickelt und der Schweißstelle zugeführt. Je größer, die Drahtlänge zwischen Rolle und Schweißstelle und je stärker der Draht ist, um so schwieriger ist es, eine einwandfreie Abwicklung 'des Drahtes von der Rolle und damit eine einwandfreie Zuführung zur Schweißstelle zu erreichen. Die sich, hierdurch, ergebenden Schwierigkeiten können gemäß der Erfindung durch folgende Anordnung vermieden werden: Zwischen Drahttrommel und Vorschubwerk wird ein Transportwerk eingeschaltet und das Transportwerk durch einen Motor angetrieben, dessen Drehzahl durch, eine Regeleinrichtung beeinflußt wird, welche in Abhängigkeit von der Spannung des Schweißdrahtes zwischen Vorschubwerk und Transportwerk arbeitet.The automatic welding machine welds from the roll. "This one is on Welding wire wound up and is unwound by a transport mechanism and the welding point fed. The greater the wire length between the roll and the weld and depending The stronger the wire, the more difficult it is to unwind properly from the roll and thus to achieve a perfect feed to the welding point. The difficulties resulting from this can be overcome according to the invention The following arrangement can be avoided: Between the wire drum and the feed mechanism a transport mechanism switched on and the transport mechanism driven by a motor, whose speed is influenced by a control device, which depends on the tension of the welding wire between the feed mechanism and the transport mechanism.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung dargestellt. Der, Schweißdraht ι ist auf einer Trommel 2 aufgewickelt ■und wird durch ein Vorschub- und Streckwerk 3/ durch einen Elektromotor 4 und ein Getriebe 5 vorgeschoben. Diesem Vorschubwerk ist ein Transportwerk vorgeschaltet, das aus einem Antriebsmotor 6 und einem Getriebe 7 besteht. Der Schweißdraht 1 ist ferner über eine Rolle 8 geführt, die an Federn 9 und 10 aufgehängt ist. Mit dieser Führung ist ein Hebel-11 gekuppelt, der zur Veränderung eines Widerstandes 12 dient, welcher in den Erregerstromkreis 13 des Motors 6 eingeschaltet ist.' Außerdem ist noch eine bekannte, nicht näher dargestellte Schaltvorrichrung 14 vorgesehen, um die Geschwindigkeit des Motors 6 mit der des Motors 4 in Einklang zu bringen.An embodiment of the invention is shown in the figure. The one, welding wire ι is wound on a drum 2 ■ and is fed by a feed and drafting system 3 / advanced by an electric motor 4 and a transmission 5. This feed mechanism a transport mechanism is connected upstream, which consists of a drive motor 6 and a gearbox 7 consists. The welding wire 1 is also guided over a roller 8 which is attached to springs 9 and 10 is hung. With this guide is a lever-11 coupled, which is used to change a resistor 12 is used, which is switched into the excitation circuit 13 of the motor 6 is.' In addition, there is a known switching device 14, not shown in detail provided to the speed of the motor 6 with that of the motor 4 in line bring to.
Wenn infolge von aufgetretenen Differenzen zwischen den Geschwindigkeiten dieser beiden Motoren sich die zwischen den beiden Transportwerken, angeschlossene Drahtlänge ändert, so führt das zu einer Verstellung der Rolle 8. Ist die Transportgeschwindigkeit des Vor-Schuhwerkes 3 größer als die des Transportwerkes 7, so wird die Rolle 8 nach unten bewegt Und dadurch der Widerstand 12 so verändert, daß die Geschwindigkeit des Motors 6 zunnnmt, also mehr Draht von der Rolle ahgewickelt wird. Umgekehrt wird, wenn der Motor 6 zu schnell läuft, "die Rolle 8 nach oben geschoben und hierdurch der Motor 6 auf leine geringere Geschwindigkeit eingeregelt.If as a result of differences occurred between the speeds of these two Motors, the wire length connected between the two transport units changes, this leads to an adjustment of the roller 8. Is the transport speed of the front footwear 3 larger than that of the transport mechanism 7, the roller 8 is moved downwards And thereby the resistance 12 changes so that the speed of the motor 6 increases, that is, more wire is wound off the roll will. Conversely, if the motor 6 is running too fast, the roller 8 will follow pushed up and thereby the motor 6 adjusted to a lower speed.
