Description

Die Erfindung befaßt sich mit einer Elektrodenanordnung zum Verschweißen thermoplastischer Kunststoffe von annähernd gleichem Querschnitt im hochfrequenten Konsensatorfeld. Hierbei tritt häufig das Problem auf, die Form und Ausdehnung eines Gegenstandes durch eine Schweißnaht zu begrenzen und zur Ersparnis von Arbeitszeit gleichzeitig noch weitere Schweiß nagen an demselben Gegenstand auszuführen. Es ist bereits bekannt, durch besondere Formgebung der Elektroden gleichzeitig verschiedene Schweißungen durchzuführen, und zwar mit unterschiedlicher Feldstärke sowie entsprechend unterschiedlicher Festigkeit der Nähte bzw. unterschiedlichen Materialstärken an den Schweiß stellen. The invention is concerned with an electrode assembly for welding thermoplastics of approximately the same cross-section in the high-frequency Consensator field. The problem often arises here, the shape and extent of a To limit the object by a weld seam and to save working time at the same time still gnaw more sweat on the same object. It is already known, due to the special shape of the electrodes, different at the same time Carry out welds, with different field strengths and accordingly different strength of the seams or different material thicknesses put the sweat.

Zweck der Erfindung ist es, dieses Ziel' auf einfachere Weise durch Verwendung mehrerer mit unterschiedlichen Spannungen beaufschlagter Elektroden zu erreichen. Gemäß der Erfindung sind ein an der vollen Spannung liegendes Elektrodenpaar und eine oder mehrere an Teilspannungen des Generators liegende weitere Elektroden vorgesehen, so daß gleichzeitig zwei oder mehrerre Schweißungen mit unterschiedlichen Feldstärken sowie entsprechend unterschiedlicher Festigkeit der Nähte bzw. unterschiedlichen Materialstärken an den Schweiß steilen ausgeführt werden. The purpose of the invention is to achieve this goal in a simpler way Use of several electrodes with different voltages applied to them reach. According to the invention are a pair of electrodes at full voltage and one or more additional electrodes connected to partial voltages of the generator provided so that at the same time two or more welds with different Field strengths as well as correspondingly different strengths of the seams or different Material thicknesses are carried out on the welding steep.

Eine Ausführungsform sei an der Abbildung näher erläutert. Bei dem zu verschwei.ßenden Gegenstand wird eine Randverstärkung durch Umlegen der Folien I und' 2 an den Steilen 8 und 9. erzielt. One embodiment is explained in more detail in the illustration. In which The object to be welded is reinforced by turning the foils over I and '2 at steep 8 and 9.

Während des Schweißvorganges an der Stelle 5 sollen die umgelegten Enden 8 und 9 nur nageheftet werden, damit sie ihre Stärke nicht verlieren. Zu diesem Zweck wird die Speisung der Folien in diesem Bereich nur mit der halben Feldstärk durchgeführt, indem eine Hilfselektrode 10 an den Symmetriepunkt des HF-Generators 11 angeschlossen wird. Hierdurch werden die umgelegten Kanten der Folien aufgeschweißt, nicht jedoch werden an dieser Stelle Folien I und 2 verschweißt.During the welding process at point 5, the folded Ends 8 and 9 are only tacked on so that they do not lose their strength. To this The purpose is to feed the foils in this area with only half the field strength performed by placing an auxiliary electrode 10 at the symmetry point of the RF generator 11 is connected. As a result, the folded edges of the foils are welded on, however, foils I and 2 are not welded at this point.

Es können im Rahmen der Erfindung auch weitere an Teilspannungen legende Elektroden zur Erzielung der notwendigen Feldstärken und Festigkeit bzw. Materialstärke vorgesehen sein. Within the scope of the invention, further partial voltages can also be used Laying electrodes to achieve the necessary field strengths and strength or Material thickness can be provided.
