Description

Um bei der Verleimung von Gutteilen verhältnismäßig großer Länge in: einem elektrischen Hochfrequenzfel-d das Gut möglichst ungehindert auf den Arbeitsplatz auflegen bzw. von diesem entfernen zu .können und um während der Zuführung der Hochfreqüenzenerge die richtigen Spannungsverhältnisse einstellen zu können, ist im Patent 874626 vorgeschlagen worden, mindestens eine der beiden Feldelektroden in Einzelelektroden aufzuteilen und diese unabhängig voneinander beweglich, .z. B. vom Gut wegklappbar, zu gestalten. Da die besonderen Verhältnisse bei der Verleimüng großer Werkstücke es erforderlich machen, daß d,ie Einzelelektroden auch unabhängig voneinander ver schwenkt und vom Gut weggeklappt werden können; bedeutet die Herstellung und Lösung einer einwandfreien elektrischen Verbindung zwischen den einzelnen Elektroden unmittelbar vor der Einschaltung Ader Höchfrequenzenergie und nach deren Abschaltung, insbesondere bei Werkstücken sehr .größer Länge, eine zeitraubende Arbeit, (da unter Umständen nicht nur zwei oder drei, sondern sogar zwanzig und mehr Verbindungsstellen hergestellt bzw. gelöst werden müssen.In order to be able to use a relatively long length when gluing good parts: an electrical high-frequency field, the goods as unhindered as possible to the workplace to be able to hang up or remove from it and during the supply of the high-frequency energy To be able to set the correct voltage ratios is suggested in patent 874626 been to divide at least one of the two field electrodes into individual electrodes and these can be moved independently of each other, e.g. B. fold away from the property to shape. Because of the special conditions when gluing large workpieces, it is necessary make that the individual electrodes also pivot independently of each other and from the Can be folded away well; means the production and solution of a flawless electrical connection between the individual electrodes immediately before switching on High-frequency energy core and after it has been switched off, especially with workpieces very long, a time-consuming job (since not only two or three, but even twenty or more connection points made or released Need to become.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, -daß an den Enden der Einzelelektroden Metallaschen angebracht sind; gegen die, mindestens während des Betriebes der Einrichtung; die Einzelelektroden untereinander elektrisch verbindende Überbrückungsglieder andruckbar .sind. Vorteilhaft ist es, die Metallaschen zu der vom Gut abgekehrten Seite der Einzelelektroden hin zurückzubiegen.According to the invention, these disadvantages are avoided -that Metal tabs are attached to the ends of the individual electrodes; against them, at least during the operation of the facility; the individual electrodes are electrically connected to each other connecting bridging links are printable. It is advantageous to use the metal tabs to bend back to the side of the individual electrodes facing away from the material.

Die Überbrückungsglieder bestehen vorteilhaft aus einer Platte aus isolierendem bzw: verlustarmem Werkstoff, die an ihrer den Metallaschen zugewendeten Seite mit einem metallischen Belag versehen ist.The bridging members advantageously consist of a plate insulating or: low-loss material that turned towards the metal tabs Side is provided with a metallic coating.

Ferner ist es vorteilhaft, die Überbrückungsglieder einzeln, in Gruppen oder alle gemeinsam durch eine Andruckeinrichtung gegen die Metalllaschen anzudrücken.It is also advantageous to use the bridging links individually, in groups or to press all of them together against the metal tabs by a pressure device.

Ein Ausführungsbeispiel der Erfindung wird an Hand der Figur näher erläutert. -Die Figur zeigt eine Verleimungseinrchtung in perspektivischer Darstellung. Das zu .behandelnde Gut i besteht aus einzelnen. Lamellen 2 großer Länge, ,die aufeinandergeleimt werden sollen. Seitlich .des Gutes sind die Behandlungselektroden 3 und 4 angeordnet. Die Elektrode 3 besteht aus einem Stück, während die Elektrode 4 in Einzelelektroden 4, 4' usf. aufgeteilt ist. Die Einzelelektroden 4, 4' usf: sind um eine Achse 5 verschwenkbar, um .das Gut i in möglichst einfacher Weise an Ort bringen zu können. Die Elektroden q., 4' usf. sind allseits verkleidet, um das Bedienungspersonal durch die verwendeten hohen Spannungen nicht zu gefährden. Gegen die Rückseite der Verkleidung 6 sind- mit der -Elektrode 7 verbundene metallische Laschen $ herausgeführt. Vor Anlegung der Hochfrequenzenergie müssen die Elektroden 4, d' usf. miteinander elektrisch, leitend verbunden werden. Zu diesem Zweck ist an den Stoßstellen zwischen den einzelnen Elektroden je ein überbrückungsglied g angeordnet, das an seiner den Laschen 8 zugekehrten Fläche mit einem metallischen Belag ro versehen ist. Beim Anpressender Verbindungsglieder 9 gegen das Ende der einen und den Anfang der nächsten Elektrode wird die Lasche 8 über den Metallbelag io des Überbrückungsgliedes 9 mit der Lasche 8' der nächsten Elektrode 4' verbunden.An exemplary embodiment of the invention is explained in more detail with reference to the figure explained. -The figure shows a gluing device in perspective. The good i to be treated consists of individual items. Slats 2 of great length, which are glued together should be. The treatment electrodes 3 and 4 are arranged on the side of the goods. The electrode 3 consists of one piece, while the electrode 4 consists of individual electrodes 4, 4 'etc. is divided. The individual electrodes 4, 4 'etc. are about an axis 5 pivotable, in order to be able to bring the good i in place in the simplest possible manner. The electrodes q., 4 'etc. are covered on all sides so that the operating staff can pass through not to endanger the high voltages used. Against the back of the panel 6 metallic tabs $ connected to the electrode 7 are brought out. before Applying the high-frequency energy, the electrodes 4, d 'etc. must be electrically connected to one another, be conductively connected. For this purpose it is at the joints between each Electrodes each have a bridging member g arranged on its facing the tabs 8 Surface is provided with a metallic coating ro. When pressing the connecting links 9 towards the end of one electrode and the beginning of the next electrode becomes the tab 8 over the metal covering io of the bridging member 9 with the tab 8 'of the next Electrode 4 'connected.

Es ist zweckmäßig; die .metallischen Laschen 8 federnd auszubilden, um eine elektrisch einwandfrei:c Verbindung Oder Einzelelektraden über das Überbrückungsglied g zu gewährleisten.It's convenient; to form the .metallic tabs 8 resilient, To ensure an electrically perfect: c connection or individual electrodes via the bridging link g to ensure.

Die Erfindung ist in holzverarb°iten.den Betrieben, insbesondere .in Möbeltischlereien, Bootsbaubetrieben und bei der Flugzeugherstellung, anwendbar.The invention is used in wood processing companies, in particular in Cabinet makers, boat builders and aircraft manufacturing, applicable.
