Vorrichtungen zur Behandlung von Oberflächen von Werkstücken verschiedener Abmessungen mit elektrischen Entladungen zur Steigerung der Benetzbarkeit und Haftfähigkeit z.B. durch Druckfarben sind derzeitiger Stand der Technik (siehe DE 3039951 und DE 3219528). Auch Anlagen zur Behandlung von laufenden Kabeln sind bekannt.Devices for treating the surfaces of workpieces of different dimensions with electrical discharges to increase wettability and adhesion, e.g. through printing inks, are currently state of the art (see DE 3039951 and DE 3219528). Systems for treating running cables are also known.
Um in der gleichen Anlage Kabel unterschiedlicher Dicke zu behandeln, wird derzeit ein unverhältnismäßiger Aufwand getrieben, der zusammen mit einer bedienerunfreundlichen Justage die bisherigen Anlagen nicht praxisgerecht erscheinen läßt. Gleichzeitig sollte mit einem neuen Behandlungswerkzeug die Beschädigung der Kabelisolation durch die behandelnden elektrischen Entladungen mit Sicherheit ausgeschlossen werden.In order to treat cables of different thicknesses in the same system, a disproportionate amount of effort is currently being made, which, together with adjustment that is not user-friendly, makes the existing systems appear impractical. At the same time, a new treatment tool should be used to ensure that damage to the cable insulation caused by the electrical discharges used during treatment is ruled out.
Aufgabe der hier vorgestellten Vorrichtung ist es, den apparativen Aufwand zu verringern und mit einer Vorrichtung ohne weitere Justagen alle Kabel mit einem Durchmesser von ca. 1 mm bis ca. 10 mm mit elektrischen Entladungen einseitig zu behandeln.The purpose of the device presented here is to reduce the amount of equipment required and to treat all cables with a diameter of approx. 1 mm to approx. 10 mm with electrical discharges on one side using a device without any further adjustments.
Die Aufgabe wird mit der Anordnung der Abbildung 1 gelöst. Das Behandlungswerkzeug besteht aus einem metallischen Gehäuse (1), das elektrisch geerdet ist. Das Gehäuse enthält eine Bohrung (2) zur Absaugung der ozonhaltigen Abluft, die zwangsläufig bei elektrischen Entladungen in sauerstoffhaltiger Luft entsteht. (3) ist die Durchführung der elektrischen Versorgungsspannung. An gegenüberliegenden Seiten des Gehäuses befindet sich jeweils ein Eintrittsspalt (4) für das zu behandelnde Kabel (6) bzw. ein Austrittsspalt (5). Geführt wird das Kabel von jeweils mindestens einer Rolle (7, 8) am Eintritts- und Austrittsspalt, die derart justiert sind, daß die Rollenoberkanten und damit die Kabelunterseite 1,5 mm oberhalb der sich im Gehäuse befindlichen etwa 10 cm langen Behandlungselektrode (9) befinden. Die Behandlungselektrode ist mit einer elektrisch isolierenden Schicht (10) versehen, die für den Entladungsstrom eine elektrische Barriere bildet und einen Durchschlag durch die Kabelisolation verhindert. Ist das Kabel mit einer sehr dicken Isolation verhindert, die mit Sicherheit einen elektrischen Durchschlag verhindert, wird zweckmäßigerweise eine unbeschichtete Elektrode verwendet.The task is solved with the arrangement in Figure 1. The treatment tool consists of a metal housing (1) that is electrically grounded. The housing contains a hole (2) for extracting the ozone-containing exhaust air that inevitably occurs during electrical discharges in oxygen-containing air. (3) is the passage of the electrical supply voltage. On opposite sides of the housing there is an entry slot (4) for the cable to be treated (6) and an exit slot (5). The cable is guided by at least one roller (7, 8) at the entry and exit slots, which are adjusted in such a way that the upper edges of the rollers and thus the underside of the cable are 1.5 mm above the approximately 10 cm long treatment electrode (9) located in the housing. The treatment electrode is provided with an electrically insulating layer (10) which forms an electrical barrier for the discharge current and prevents breakdown through the cable insulation. If the cable is provided with very thick insulation which reliably prevents electrical breakdown, it is advisable to use an uncoated electrode.
Wird die Elektrode mit dem Hochspannungsausgang und das zu behandelnde Kabel mit der Masseseite eines geeigneten elektrischen Versorgungsgerätes verbunden, treten zwischen Elektrode und Kabel elektrische Entladungen auf. In diesen Entladungen wird die Oberfläche der Isolation des Kabels oxidiert und somit durch die hiermit verbundene Erhöhung der Benetzbarkeit der erwünschte Vorbehandlungseffekt an dem mit hoher Geschwindigkeit durch die Station gezogenen Kabel erhalten. Bei Kabelwechsel wird der Deckel der Station geöffnet und das Kabel von oben auf die Rollen (7) und (8) aufgelegt. Der optimale Behandlungsabstand von 1,5 mm zu der Behandlungselektrode stellt sich automatisch ein.If the electrode is connected to the high-voltage output and the cable to be treated is connected to the ground side of a suitable electrical supply device, electrical discharges occur between the electrode and the cable. In these discharges, the surface of the cable's insulation is oxidized and the associated increase in wettability results in the desired pretreatment effect on the cable pulled through the station at high speed. When changing the cable, the cover of the station is opened and the cable is placed on the rollers (7) and (8) from above. The optimal treatment distance of 1.5 mm from the treatment electrode is set automatically.
