Abstract

The skid has a radiography equipment for varnishing a body of a motor vehicle. An electrically conductive contact blade (4) is connected to the radiography equipment, and vats (1) are arranged on the radiography equipment. The vats are electrically isolated from the contact blade by an electrical isolator (5), and are manufactured from electrically isolated material e.g. hard plastic.

Description

Die Erfindung betrifft einen Transportskid für eine kathodische Tauchlackieranlage gemäß dem Oberbegriff des Anspruchs 1, wie er bspw. aus der gattungsbildend zugrundegelegten DE 43 03 171 C1 als bekannt hervorgeht.The invention relates to a Transportkid for a cathodic dip painting system according to the preamble of claim 1, as he, for example, based on the generic DE 43 03 171 C1 as known.

Aus der gattungsbildend zugrunde gelegten DE 43 03 171 C1 ist ein Transportskid bekannt, wie er zur kathodischen Tauchlackierung (KTL) von Pkw-Karosserien verwendet wird. Der Transportskid weist als Aufnahmeeinrichtung für die Karosserie einen Halterahmen auf, an dem eine Karosserie elektrisch leitend und relativ zum Halterahmen ortsfest an diesem festgelegt werden kann. Mit dem Halterahmen ist ein Kontaktschwert elektrisch leitend verbunden, das im Betrieb mit einer Spannungsquelle im Eingriff steht. Dadurch kann an den Transportskid und damit auch an die Karosserie eine definierte Spannung angelegt werden. Unterhalb des Halterahmens sind Kufen angebracht, die im Betrieb über Rollen gleiten, so dass Transportskid mit der darauf angeordneten Karosserie auf einfache Weise durch ein Tauchbad hindurchbewegt werden kann. Bei dem Transport durch das Tauchbad wird die Karosserie sowie der Transportskid elektrochemisch beschichtet. Durch den Transport des Transportskids auf Rollenbahnen erfolgt ein mechanischer Abtrag von Lack an den zuvor beschichteten Kufen des Transportskids, wodurch die Rollen, auf denen die Kufen gleiten, stark verschmutzt werden. Damit ein störungsfreier Betrieb erfolgen kann, müssen diese Rollen ständig bzw. in kurzen Intervallen gereinigt werden. Hiermit ist ein hoher Zeit- und Kostenaufwand verbunden.From the genre forming basis DE 43 03 171 C1 a transport kit is known, as it is used for cathodic dip painting (KTL) of car bodies. The Transportkid has as a receiving device for the body to a support frame on which a body electrically conductive and relative to the support frame can be fixed fixed to this. With the holding frame, a contact blade is electrically connected, which is in operation with a voltage source in engagement. As a result, a defined voltage can be applied to the transport carriage and thus also to the body. Runners are mounted below the holding frame, which slide over rollers during operation, so that transport carriage with the body arranged thereon can be easily moved through a dipping bath. During transport through the dipping bath, the body and the transport kit are electrochemically coated. By transporting the Transportkids on roller conveyors, a mechanical removal of paint takes place on the previously coated runners of the Transportkids, whereby the rollers on which the runners slide, are heavily contaminated. To ensure trouble-free operation, these rollers must be cleaned constantly or at short intervals. This is associated with a high time and cost.

Die Aufgabe der Erfindung ist es, den Zeit- und Kostenaufwand beim Betrieb einer KTL-Anlage zu verringern.The The object of the invention is the time and cost of operation a KTL plant.

Die Aufgabe wird bei einem Transportskid mit den Merkmalen des Anspruchs 1 gelöst. Durch die elektrische Isolation zumindest der Kufen gegenüber dem Kontaktschwert liegt an den Kufen keine elektrische Spannung an, wodurch der Lackauftrag pro Zeiteinheit und damit der Kosten- und Zeitaufwand für die Reinigung der Kufen Und/oder der Rollen zumindest verringert ist.The Task becomes in a Transportkid with the features of the claim 1 solved. Due to the electrical insulation of at least the skids against the Contact blade is at the runners no electrical voltage, whereby the paint application per unit time and thus the cost and Time required for cleaning the skids and / or rollers at least reduced is.

Sinnvolle Ausgestaltungen der Erfindung sind den Unteransprüchen entnehmbar. Im übrigen wird die Erfindung anhand eines in der einzigen Figur dargestellt Ausführungsbeispieles näher erläutert.meaningful Embodiments of the invention are the dependent claims. Otherwise, will the invention with reference to an embodiment shown in the single FIGURE explained in more detail.

Die einzige Figur zeigt einen Transportskid mit zwei parallel zur Transportrichtung ausgerichtete Kufen 1. Auf den Kufen 1 sind quer dazu ausgerichtete Querträger 2 angeordnet sind. An den Querträgern 2 sind Aufnahmezapfen 3 angebracht.The single figure shows a Transportkid with two parallel to the transport direction runners 1 , On the skids 1 are transversely aligned cross member 2 are arranged. At the crossbeams 2 are spigots 3 appropriate.

Die Aufnahmezapfen 3 bilden eine Aufnahmeeinrichtung aus, an denen bspw. eine Kfz-Karosserie gehaltert anordenbar ist. An wenigstens einem der Querträger 2, der ferner mit wenigstens einem elektrisch dazu leitenden verbundenen Aufnahmezapfen 3 versehen ist, ist gleichfalls elektrisch leitend dazu ein Kontaktschwert 4 befestigt.The spigot 3 form a receiving device on which, for example, a motor vehicle body can be arranged is arranged. At least one of the cross members 2 further comprising at least one electrically conductive associated spigot 3 is provided, is also electrically conductive to a contact sword 4 attached.

Das Kontaktschwert 4 wird während des Betriebs entlang einer Stromschiene bewegt, so dass es währenddessen ein vorgebbares elektrisches Potential aufweist. Da der Aufnahmezapfen 3 mit der darauf anzuordnenden Karosserie elektrisch leitend verbunden ist, liegt die Karosserie während dem Transport durch das Tauchbad auf dem gleichen elektrischen Potential wie das Kontaktschwert 4.The contact sword 4 is moved during operation along a bus bar, so that it has meanwhile a predeterminable electrical potential. Because the spigot 3 is electrically connected to the body to be arranged thereon, the body is during transport through the dip at the same electrical potential as the contact blade 4 ,

Um die Kufen 1 spannungsfrei zu halten, ist zumindest zwischen den Kufen 1 und den elektrisch leitend mit dem Kontaktschwert 4 verbundenen Querträgern 2 ein elektrischer Isolator 5 angeordnet.To the runners 1 at least between the skids 1 and the electrically conductive with the contact blade 4 connected cross members 2 an electrical insulator 5 arranged.

Bei anderen Bauformen kann der Isolator 5 auch an anderen Stellen angeordnet sein, wobei generell darauf zu achten ist, dass die Kufen 1 von dem Kontaktschwert 4 elektrisch isoliert sind.In other designs, the insulator 5 be arranged in other places, in general, it must be ensured that the runners 1 from the contact sword 4 are electrically isolated.

Ein besonders bevorzugter Transportskid wird nachfolgend beschrieben. Da dieser Transportskid weiten Bereichen baugleich zu dem Transportskid nach 1 ist, wird auf eine separate Darstellung verzichtet. Der besonders bevorzugte Transportkid weist als hervorstechendes Merkmal Kufen 1 auf, die aus einem elektrisch isolierenden Material gefertigt sind.A particularly preferred transport kit will be described below. Since this Transportkid wide areas identical to the Transportkid after 1 is, is waived a separate presentation. The particularly preferred Transportkid has as salient feature runners 1 on, which are made of an electrically insulating material.
