Abstract

A device for holding hollow bodies of electrically conductive material, such as cans of sheet metal, while they are conveyed through an electrophoretic dip bath, is provided with a conveying element which runs through the dip bath, which seizes in succession the open ends of the individual hollow bodies and temporarily holds them. For this purpose, at least three electrically conductive holders for the individual hollow bodies are arranged on the conveying element, which holders are rotatable about a shaft and form gripping devices for seizing, in a detachable manner, the edge of a respective hollow body. The holders are preferably conical pegs, on the surface of the sheath of which threads are arranged as gripping devices, which threads are interrupted at at least one point.

Description

Die Erfindung betrifft eine Vorrichtung zum Halten von Hohlkörpern aus elektrisch leitendem Material, beispielweise Dosen aus Metallblech, während dieselben durch ein elektrophoretisches Tauchbad bewegt werden, mit einem durch das Tauchbad laufenden Transportelement, das die einzelnen Hohlkörper in einer fortlaufenden Folge an ihrem einen nach außen gebördelten Rand aufweisenden offenen Ende ergreift und vorübergehend festhält.The invention relates to a device for holding hollow bodies made of electrically conductive material, for example cans made of sheet metal, while they are being moved through an electrophoretic immersion bath, with a transport element which runs through the immersion bath and which, in a continuous sequence, crimps the individual hollow bodies outwards at their one Grips open end and temporarily holds.

In P 33 04 940.8 ist ein Verfahren zum Beschichten einseitig offener Hohlkörper beschrieben, bei dem die einzelnen Hohlkörper gewaschen, außen und innen mit einem Lack beschichtet, dann getrocknet und danach ggfs. bedruckt und erneut getrocknet werden. Die Hohlkörper wie Dosen werden in einem kontinuierlichen Arbeitsgang derart durch ein Elektrotauchbad hindurchgeführt, daß sie schnell und vollständig mit Tauchbadflüssigkeit geflutet werden, um sie elektrophoretisch mit einem Naßfilm zu beschichten. Nach ausreichender Beschichtungszeit werden die Hohlkörper wieder aus dem Tauchbad ausgehoben und die in ihnen befindliche Tauchbadflüssigkeit ausgegossen. Während dieser Behandlung sollen sie an ihrem gebördelten offenen Ende derart erfaßt werden, daß die Halterung zugleich als Kontaktelektrode wirkt, der eine im Abstand von der Wand des Hohlkörpers befindliche innere Gegenelektrode zugeordnet ist.P 33 04 940.8 describes a process for coating hollow bodies which are open on one side, in which the individual hollow bodies are washed, coated on the outside and inside with a lacquer, then dried and then, if appropriate, printed and dried again. The hollow bodies, such as cans, are passed through an electro-immersion bath in a continuous operation in such a way that they are quickly and completely flooded with immersion bath liquid in order to electrophoretically coat them with a wet film. After a sufficient coating time, the hollow bodies are lifted out of the immersion bath and the immersion bath liquid contained in them is poured out. During this treatment, they should be grasped at their flared open end in such a way that the holder also acts as a contact electrode, which is assigned an inner counterelectrode located at a distance from the wall of the hollow body.

Während in P 33 04 940.8 der Verfahrensablauf zum elektrophoretischen Beschichten von einseitig geschlossenen Hohlkörpern wie metallischen Dosen im einzelnen offenbart ist, sind Einzelheiten der zum Durchführen dieses Verfahrens zu benutzenden Haltevorrichtung nicht offenbart.While the process sequence for electrophoretic coating of hollow bodies closed on one side, such as metallic cans, is disclosed in detail in P 33 04 940.8, details of those to be used for carrying out this method are to be used Holding device not disclosed.

Aufgabe der Erfindung ist es, eine zum Durchführen des Verfahren; gemäß P.33 04 940.8 geeignete Haltevorrichtung für die zu beschichtenden Hohlkörper, während dieselben durch das elektrophoretische Tauchbad bewegt werden, zu schaffen, welche die Hohlkörper zuverlässig und sicher ergreift und nach dem Verlassen des Tauchbades abgibt und welche einen guten elektrischen Kontakt zwischen der als Elektrode ausgebildeten Halterung und den einzelnen Hohlkörpern gewährleistet.The object of the invention is to carry out the method; according to P.33 04 940.8 to provide a suitable holding device for the hollow bodies to be coated while they are being moved through the electrophoretic immersion bath, which grips the hollow bodies reliably and safely and releases them after leaving the immersion bath and which provides good electrical contact between the electrodes trained bracket and the individual hollow bodies guaranteed.

Diese Aufgabe wird erfindungsgemäß mit einer Vorrichtung der eingangs genannten Gattung gelöst, welche die kennzeichnenden Merkmale des Hauptanspruches aufweist. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved with a device of the type mentioned, which has the characterizing features of the main claim. Advantageous embodiments of the invention are the subject of the dependent claims.

Die kegelförmigen Halter, von denen vorzugsweise drei auf einem Kreis im gleichmäßigen Abstand voneinander verteilt angeordnet sind, können den nach außen umgebördelten Rand der einzelnen zu beschichtenden Hohlkörper wie Dosen erfassen oder freigeben, und zwar dadurch, daß sie gemeinsam um ihre jeweilige Längsachse verdreht und/oder tangential zum umgebördelten Rand verschoben werden- Werden die als kegelförmige Zapfen ausgebildeten Halter um ihre jeweilige Längsachse verdreht, erfassen sie den nach außen gebördelten Rand der einzelnen Hohlkörper und ziehen ihn fest, wobei der verhältnismäßig scharfkantige Rand der metallischen Hohlkörper sozusagen in die Oberfläche der Halter und insbesondere einer dort befindlichen Lackschicht einschneidet, so daß ein elektrischer Kontakt zwischen den aus elektrisch leitendem Material bestehenden und an den einen Pol der elektrischen Stromquelle angeschlossenen Haltern und den metallische Hohlkörpern mit Sicherheit hergestellt wird. Werden die Halter tangential zum gebördelten Rand der Hohlkörper verschoben, ergibt sich ein gleicher Einschneideffekt, der noch durch eine zusätzliche Verdrehung der Halter verbessert werden kann. die kegelförmigen Zapfen oder Halter nur einen geringen Durchmesser aufzuweisen brauchen, ist auch nur ein äußerst kleiner mechanischer Schaltweg erforderlich, beispielsweise eine Viertel drehung der Zapfen oder eine kurze tangentiale Bewegung.The conical holders, of which three are preferably arranged on a circle at a uniform distance from one another, can grasp or release the edge of the individual hollow bodies to be coated, such as cans, which is flanged outwards, by rotating them together about their respective longitudinal axis and / or be moved tangentially to the flanged edge - If the holders, which are designed as conical pins, are rotated about their respective longitudinal axes, they grip the edge of the individual hollow bodies, which is flanged outwards, and tighten it, whereby the relatively sharp-edged edge of the metallic hollow bodies, so to speak, into the surface of the holder and in particular cuts into a lacquer layer located there, so that an electrical contact between the holders consisting of electrically conductive material and connected to the one pole of the electrical power source and the metallic hollow bodies is produced with certainty. If the holders are moved tangentially to the flanged edge of the hollow body, the same cutting effect results, which can be improved by an additional rotation of the holder. the conical pins or holders need only have a small diameter, only an extremely small mechanical switching path is required, for example a quarter turn of the pin or a short tangential movement.

Wenn die kegelförmigen Zapfen oder Halter als Greifelemente . auf ihrer Mantelfläche Gewindegänge, erhabene gespreizte Führung federn oder gespreizte Führungsrillen aufweisen, deren Teilung bzw. lichter Abstand auf die Wandstärke der zu erfassenden Hohlkörper abgestellt ist, ergibt sich beim Festziehen des gebördelten Randes der Hohlkörper an den Haltern eine besonders gute Schnittbewegung des einen Grat aufweisenden scharfen gebördelten Randes der Hohlkörper, wenn es sich um Blechdosen handelt, so daß der auf den kegelförmigen Zapfen bzw. Haltern befindliche Überzug des Beschichtungsmaterials vollständig durchschnitten und dementsprechend ein einwandfreier elektrische Kontakt zwischen dem die eine Elektrode bildenden, aus elektrisc leitendem Material bestehenden Halter und den zu beschichtenden Hohlkörper erzielt wird. Die am gebördelten Rand gebildeten Kontaktstellen zwischen Hohlkörper und Haltern, welche im Tauchbad nicht beschichtet werden, sind äußerst klein und befinden sich nur an der Außenkante des gebördelten Randes. Diese Stellen verschwinden beim Verschließen des Hohlkörpers bzw. der Dose mit einem Deckel in dem dabei gebildeten Falz und sind daher am verschlossenen Hohlkörper keinen korrosiven Einflüssen ausgesetzt.If the conical pins or holders as gripping elements. on its lateral surface, threads, raised splayed guide springs or splayed guide grooves, the pitch or spacing of which is based on the wall thickness of the hollow body to be detected, results in a particularly good cutting movement of the burr when tightening the flanged edge of the hollow body on the holders sharp flanged edge of the hollow body, when it comes to tin cans, so that the coating of the coating material located on the conical pins or holders is completely cut through and accordingly a perfect electrical contact between the electrode-forming holder, consisting of electrically conductive material, and the hollow body to be coated is achieved. The contact points formed on the flanged edge between the hollow body and holders, which are not coated in the immersion bath, are extremely small and are only located on the outer edge of the flanged edge. These points disappear when the hollow body or the can is closed with a lid in the fold formed in the process and are therefore not exposed to any corrosive influences on the closed hollow body.

Während des Einsetzens der Hohlkörper in die Haltevorrichtung und des Entfernes derselben aus der Haltevorrichtung ist ein elektrischer Kontakt zu den Haltern oder drehbaren Zapfen nicht zweckmäßig. Daher sind diese Halter nach einem weiteren Merkmal der Erfindung beispielsweise mit einem elektrisch isolierenden Einsatz aus Kunststoff oder einer elektrisch isolierenden Kappe aus Kunststoff versehen. Auf. diesen elektrisch isolierenden Teilen können die gebördelten Ränder der einzelnen Hohlkörper beim Einsetzen zum Zentrieren verschoben werden, ohne daß sich Beschädigungen am gebördelten Rand ergeben. / 3aDuring the insertion of the hollow bodies into the holding device and the removal thereof from the holding device, electrical contact with the holders or rotatable pins is not expedient. Therefore, according to a further feature of the invention, these holders are provided, for example, with an electrically insulating insert made of plastic or an electrically insulating cap made of plastic. On. these electrically insulating parts, the flanged edges of the individual hollow bodies can be displaced for centering when inserted, without causing damage to the flanged edge. / 3a

\ Ist der Hohlkörper zwischen den drehbaren Zapfen zentriert, wird der elektrische Kontakt zu dem leitenden Teil der einzelnen drehbaren Zapfen durch Drehen bzw. Weiterdrehen derselben um deren Längsachse hergestellt, wobei der gebördelte Rand fest an die drehbaren Zapfen gezogen wird und einen auf deren Oberfläche befindlichen Überzug aus Beschichtungsmaterial mit Sicherheit durchschneidet.\ If the hollow body is centered between the rotatable pins, the electrical contact to the conductive part of the individual rotatable pins is made by turning or turning them about their longitudinal axis, the flanged edge being pulled firmly against the rotatable pin and one located on its surface Coating from coating material will certainly cut through.

Die erfindungsgemäße Vorrichtung bildet eine einwandfreie mechanische Halterung mit selbstreinigendem elektrischem Kontakt welche ein problemloses Einsetzen der einzelnen zu beschichtende Hohlkörper für die Tauchbadbeschichtung und ein kippfreies Entladen auf ein Transportband oder dergleichen nach dem Beschichten ermöglicht.The device according to the invention forms a perfect mechanical holder with self-cleaning electrical contact, which enables the individual hollow bodies to be coated to be inserted without problems for the immersion bath coating and a tilt-free unloading onto a conveyor belt or the like after the coating.

Mit dieser Vorrichtung ist man in der Lage, im 10 Sekunden Abscheidebereich mit hochgeregelter Abscheidespannung wirtschaft lich zu arbeiten, weil nur verhältnismäßig geringe Punktkontakte an dem beispielsweise 0,1 mm starken Bördelrand vorhanden sind.With this device one is able to operate in the 10 seconds separation range with highly regulated separation voltage Lich to work because there are only relatively small point contacts on the 0.1 mm thick flange edge, for example.

Die erfindungsgemäße Haltevorrichtung kann sowohl an Tauchrädern als auch an Tauchbalken vorgesehen werden. Die Drehbewegungen der zum Erfassen der Dosenränder vorgesehenen Drehzapfen oder kegelförmigen Halter kann beispielsweise über eine Kurvensteuerung bewirkt werden.The holding device according to the invention can be provided both on diving wheels and on diving bars. The rotary movements of the pivots or conical holders provided for gripping the edges of the can can be brought about, for example, via a cam control.

Mit der erfindungsgemäßen Haltevorrichtung werden die einzelnen Dosen so von der Vorrichtung erfaßt, daß ein Ausbrechen der Dosen beim Eintauchen in das Tauchbad und beim Ausheben aus dem Bad mit Sicherheit verhindert wird. Der mechanische Schaltweg zum Erfassen und Festhalten bzw. zum Freigeben der Dosen ist klein und exakt beispielsweise über eine Kurve steuerbar. Die Dosen werden ohne Gefahr des Taumelns oder Schrägstellens erfaßt und gehalten, so daß aufeinanderfolgende Dosen einander nicht berühren können, selbst wenn die Dosen in dichter Folge durch das Tauchbad hindurch geleitet werden. Wegen des Selbstreinigungseffektes der Drehzapfen beim Erfassen der Dosen kann sich auf diesen als Elektrode dienenden Teilen der Vorrichtung nicht ein isolierender Überzug aus dem Beschichtungsmaterial des Tauchbades bilden. Die den Drehzapfen zugeordnete Gegenelektrode kann extrem klein sein, weil ein guter Umgriff des Beschichtungsmittels möglich ist. Andererseits sind Beschädigungen der Dosen durch die Haltevorrichtung nicht zu befürchten.With the holding device according to the invention, the individual cans are gripped by the device in such a way that the cans break out when immersed in the immersion bath and when they are lifted out of the bath. The mechanical switching path for grasping and holding or releasing the cans is small and can be precisely controlled, for example, via a curve. The cans are gripped and held without the risk of wobbling or skewing so that successive cans cannot touch each other even if the cans are passed through the immersion bath in close succession. Because of the self-cleaning effect of the pivots when the cans are gripped, an insulating coating of the coating material of the immersion bath cannot form on these parts of the device which serve as electrodes. The counterelectrode assigned to the trunnion can be extremely small because it is possible to grip the coating agent well. On the other hand, there is no fear of damage to the cans due to the holding device.

ist und wenigstens eine zum Aufrechterhalten der Bandspannung nachgestellt werden kann. Auf der Außenseite des Transportbandes 10 sind Blaseinrichtungen 14 und 15 zum Ausblasen der auf dem Transportband 10 befindlichen Dosen 6 und damit zum Vortrocknen derselben vorgesehen.and at least one can be adjusted to maintain the belt tension. On the outside of the conveyor belt 10, blowing devices 14 and 15 are provided for blowing out the cans 6 located on the conveyor belt 10 and thus for pre-drying them.

Zwischen dem Transportabschnitt 2 und dem Trockenabschnitt 3 ist ein weiteres endloses Transportband 16 vorgesehen, welches die Dosen 6 vom Transportband 10 übernimmt und mit ihrer Öffnung nach oben weisend auf ein horizontales Transportband 17 absetzt, welches die Dosen 6 durch einen Trockenofen 18 hindurchführt.A further endless conveyor belt 16 is provided between the transport section 2 and the drying section 3, which takes over the cans 6 from the conveyor belt 10 and, with their opening pointing upwards, sets them down on a horizontal conveyor belt 17 which guides the cans 6 through a drying oven 18.

Da die Beschichtung im Tauchbad 4,5 elektrophoretisch vorgenommen wird, müssen die einzelnen Dosen 6 vom am Tauchbadhehälter 5 drehbar gelagerten Rad 8 nicht nur erfaßt, sondern auch an eine Elektrode angeschlossen werden. Die auf dem Außenumfang des Rades 8 vorgesehenen Haltevorrichtungen 9 sind deshalb zugleich als Elektroden ausgebildet, die an einen Pol einer nicht dargestellten elektrischen Stromquelle angeschlossen sind.Since the coating in the immersion bath 4, 5 is carried out electrophoretically, the individual cans 6 must not only be grasped by the wheel 8 rotatably mounted on the immersion bath holder 5, but also connected to an electrode. The holding devices 9 provided on the outer circumference of the wheel 8 are therefore at the same time designed as electrodes which are connected to a pole of an electrical power source (not shown).

Jede Haltevorrichtung 9 hat, wie Fig. 2 zeigt, eine Tragplatte 19, auf der zentral ein hochstehender Stift 20 befestigt ist, der ebenso wie die Tragplatte 19 aus elektrisch leitendem Material besteht. Die Tragplatte 19 ist an den anderen Pol der Stromquelle angeschlossen, so daß der Zapfen 20 als Gegenelektrode dient, welche jeweils in das Innere einer Dose 6 hineinragt, mit der Dose aber nicht in Kontakt kommen soll.As shown in FIG. 2, each holding device 9 has a support plate 19 on which a raised pin 20 is fastened centrally, which, like the support plate 19, consists of electrically conductive material. The support plate 19 is connected to the other pole of the power source, so that the pin 20 serves as a counter electrode, which projects into the interior of a can 6, but should not come into contact with the can.

Am Außenumfang der Tragplatte 19 sind radial vorstehende Arme 21 vorgesehen, welche jeweils eine durchgehende Öffnung enthalten, in die eine Büchse 22 aus elektrisch isolierendem Material eingesetzt ist, beispielsweise aus selbstschmierende Eigenschaften aufweisendem Kunststoff. Die einzelnen Büchsen dienen als Lager für den Schaft 23 eines kegelförmigen Drehzapfens 24. Die Drehzapfen 24 einschließlich deren Schaft 23 bestehen ebenfalls aus elektrisch leitendem Material und sind von der Tragplatte 19 isoliert an den anderen Pol der elektrischen Stromquelle angeschlossen. Dementsprechend bilden der Stift 20 und die Drehzapfen 24 die beiden für das elektrophoretische Beschichten der Dosen 6 benötigten Gegenelektroden.Radially projecting arms 21 are provided on the outer circumference of the support plate 19, each of which contains a through opening into which a bushing 22 made of electrically insulating material is inserted, for example made of self-lubricating plastic. The individual bushes serve as bearings for the shaft 23 of a conical pivot 24. The pivot 24, including the shaft 23, also consist of electrically conductive material and are of the support plate 19 insulated connected to the other pole of the electrical power source. Accordingly, the pin 20 and the pivot 24 form the two counter electrodes required for the electrophoretic coating of the cans 6.

Jeder Drehzapfen 24 enthält einen sich weitgehend über seine Höhe erstreckenden Einsatz 25 aus elektrisch isolierendem Material, beispielsweise Keramik oder Kunststoff. Die Einsätze 25 dienen als Gleit- und Zentrierbahn für die an der Haltevorrichtung 9 anzubringenden Dosen 6, wenn sich die Drehzapfen 24 in der in Fig. 2b dargestellten Position befinden.Each pivot pin 24 contains an insert 25 made of electrically insulating material, for example ceramic or plastic, which extends largely over its height. The inserts 25 serve as a slide and centering path for the cans 6 to be attached to the holding device 9 when the pivots 24 are in the position shown in FIG. 2b.

Die Drehzapfen 24 weisen auf ihrer Mantelfläche Gewindegänge 26 auf, welche den nach außen umgebördelten Rand 27 der einzelnen Dosen 6 erfassen, wenn man die Drehzapfen 24 aus der in Fig. 2b dargestellten Position etwa um eine Vierteldrehung in die in Fig. 2a dargestellte Position verdreht. Dadurch wird die betreffende Dose 6 am offenen Ende erfaßt und an der Haltevorrichtung 9 festgezogen. Fig. 4 zeigt, daß der nach außen umgebördelte Rand 27 der Dose 6 dabei tief in die zwischen den einzelnen Gewindegängen 26 befindliche Nut 28 eingreift und in -somit einen auf dem Drehzapfen 24 eventuell befindlichen, in der Zeichnung nicht gezeigten Überzug aus Tauchbadflüssigkeit einschneidet, um einen guten elektrisch leitenden Kontakt zu den Drehzapfen 24 herzustellen.The pivots 24 have threads 26 on their outer surface, which engage the outwardly flanged edge 27 of the individual cans 6 when the pivots 24 are rotated from the position shown in FIG. 2b about a quarter turn to the position shown in FIG. 2a . As a result, the relevant can 6 is grasped at the open end and tightened on the holding device 9. 4 shows that the outwardly flanged edge 27 of the can 6 engages deeply in the groove 28 located between the individual thread turns 26 and thus cuts into a coating of immersion bath liquid which may be located on the pivot pin 24 and is not shown in the drawing, to make good electrically conductive contact with the pivot 24.

Die zwischen den Gewindegängen 26 befindlichen Nuten 28 haben einen U-förmigen Querschnitt, so daß die äußerste Kante des umgebördelten Randes 27 nicht zwischen den Gewindegängen 26 eingequetscht und dadurch beschädigt werden kann. Dies zeigt deutlich Fig. 4.The grooves 28 located between the threads 26 have a U-shaped cross section, so that the outermost edge of the flanged edge 27 cannot be squeezed between the threads 26 and thereby damaged. This is clearly shown in FIG. 4.

Die Tragplatte 19 ist gemäß Fig. 2 am äußeren Ende einer Achse 29 befestigt. Unterhalb der Tragplatte 19 ist auf der Achse 29 ein sternförmiges Schaltglied 30 drehbar gelagert, das an einer auf der Achse 29 drehbar gehaltenen, auf einem Anschlagring 31 abgestützten Buchse 32 befestigt ist, die mit einer Steuerstange 33 versehen ist, welche mit einer nicht dargestellten Steuerkurve der Anlage'zusammenwirkt, um die jeweils gewünschten Drehbewegungen der Drehzapfen 24 zu erzeugen.The support plate 19 is attached to the outer end of an axis 29 as shown in FIG. 2. Below the support plate 19, a star-shaped switching member 30 is rotatably mounted on the axis 29, which on a on the axis 29 rotatably supported, supported on a stop ring 31 bush 32, which is provided with a control rod 33, which cooperates with a control curve, not shown, of the system 'in order to produce the respectively desired rotary movements of the pivots 24.

Auf den radialen Armen 30a des Schaltelementes 30 ist jeweils ein Stift 34 befestigt, der in eine offene Gabel 35 eingreift, die am unteren Ende jeweils einer der Büchsen 22 befestigt ist und wie diese ebenfalls aus elektrisch isolierendem Material bestehen kann. Durch Verschwenken des Hebels 33 in Richtung des Pfeiles 36 wird das Schaltelement 30 in Richtung des Pfeiles 37 verschwenkt, so daß die drei Gabeln 35 in entgegengesetzter Richtung, nämlich in Richtung der Pfeile 38/verschwenkt werden. Dementsprechend werden auch die Drehzapfen 24 in Richtung der Pfeile 38 verschwenkt.On the radial arms 30a of the switching element 30, a pin 34 is fastened, which engages in an open fork 35, which is fastened to the lower end of each of the bushings 22 and how this can also consist of electrically insulating material. By pivoting the lever 33 in the direction of the arrow 36, the switching element 30 is pivoted in the direction of the arrow 37, so that the three forks 35 are pivoted in the opposite direction, namely in the direction of the arrows 38 / . Accordingly, the pivot pins 24 are pivoted in the direction of the arrows 38.

Anschläge 39 begrenzen die Verstellbarkeit des Schaltelementes 30 auf etwa eine Vierteldrehung der Drehzapfen 24.Stops 39 limit the adjustability of the switching element 30 to approximately a quarter turn of the pivot pin 24.

Der in Fig. 5 dargestellte Drehzapfen 40 weist einen aus elektrisch leitfähigem Material bestehenden Zapfen 41 auf, auf dessen oberes Ende eine aus elektrisch isolierendem Material bestehende kegelförmige Kappe 42 aufgesteckt ist. Auf dem Kegelmantel der Kappe 42 ist eine über die Mantelfläche überstehende Führungsfeder 43 vorgesehen, die im oberen Teil 43a Rechtsdrall und im unteren Teil 43b Linksdrall aufweist. Die beiden Teile 43a und 43b der Führungsfeder 43 laufen in einer,Spitze 44 zusammen, in deren Bereich ein elektrisch leitender Kontakt 45 auf der Oberfläche des Kegelmantels liegt, der mit dem elektrisch leitenden Zapfen 41 in elektrisch leitender Verbindung steht. Von einem derartigen Drehzapfen 40 erfaßte Hohlkörper 6 kommen mit ihrem nach außen umgebördelten Rand 27 mit diesem Kontakt 45 in Berührung, wenn sie nach Drehung der Drehzapfen 40 an diesen befestigt sind, so daß die für die elektrophoretische Beschichtung erforderliche Zufuhr von elektrischem Strom gewährleistet ist.The pivot pin 40 shown in FIG. 5 has a pin 41 made of electrically conductive material, on the upper end of which a conical cap 42 made of electrically insulating material is attached. Provided on the conical surface of the cap 42 is a guide spring 43 which projects beyond the surface and has a right-hand swirl in the upper part 43a and a left-hand swirl in the lower part 43b. The two parts 43a and 43b of the guide spring 43 converge in a tip 44, in the area of which there is an electrically conductive contact 45 on the surface of the cone jacket, which is in electrically conductive connection with the electrically conductive pin 41. Hollow bodies 6 gripped by such a pivot pin 40 come into contact with this contact 45 with their flanged edge 27 when they are fastened to the pivot pin 40 after rotation, so that the supply of electrical current required for the electrophoretic coating is ensured.

Der Zapfen 41 ist zu diesem Zweck an den einen Pol einer nicht dargestellten elektrischen Stromquelle angeschlossen. Auch ist der Zapfen 41 entsprechend dem eingezeichneten Doppelpfeil 46 drehbar gelagert, um den Drehzapfen 40 zum Festziehen bzw. Freigeben der Hohlkörper 6 verdrehen zu können.For this purpose, the pin 41 is connected to the one pole of an electrical power source, not shown. The pin 41 is also rotatably mounted in accordance with the double arrow 46 shown in order to be able to turn the pivot pin 40 for tightening or releasing the hollow bodies 6.

Der in Fig. 6 dargestellte Drehzapfen 47 unterscheidet sich vom Drehzapfen 40 aus Fig. 5 lediglich dadurch, daß in die Mantelfläche der als Isolator ausgebildeten Kappe 42 eine Führungsrille 48 eingearbeitet ist, die im oberen Bereich 48a Rechtsdrall und im unteren Bereich 48b Linksdrall aufweist. Im Bereich der Spitze 49 der Führungsrille 48 enthält die Kappe 42 eine Öffnung 50, in der ein Kontakt 51 liegt, welcher mit dem elektrisch leitenden Zapfen 41 in elektrisch leitender Verbindung steht und als Stromzufuhr zu dem nach außen gebördelten Rand 27 eines von dem Drehzapfen 47 erfaßten und festgehaltenen Hohlkörpers 6 dient.The pivot 47 shown in FIG. 6 differs from the pivot 40 from FIG. 5 only in that a guide groove 48 is machined into the outer surface of the cap 42 designed as an insulator, which has a right-hand swirl in the upper region 48a and a left-hand swirl in the lower region 48b. In the region of the tip 49 of the guide groove 48, the cap 42 contains an opening 50, in which a contact 51 is located, which is in electrically conductive connection with the electrically conductive pin 41 and as a power supply to the outwardly flanged edge 27 of one of the pivot pin 47 captured and held hollow body 6 is used.
