The automatically tightening contact is used to connect electroplating racks to the product rails required for the processing sequence. The wedge action combined with the loading weight produces a nonpositive, electrically conducting connection to the product rail. Additional servicing of fixing devices is unnecessary.

Description

Die Frfindung bezieht sich auf einen selbstspannenden Kontaktkopf für Galvanikgestelle, mit welchem eine elektrisch leitende Verbindung zwischen dem Gestell und der Warenschiene hergestellt wird.The invention relates to a self-tensioning contact head for electroplating frames, with which an electrically conductive connection between the frame and the goods rail is produced.

Galvanische Anlagen bestehen aus einer Anzahl, in entsprechender Reihenfolge angeordneter Bäder, in denen zur Oberflächenveredelung vorgesehene Teile behandelt werden. Die Behandlung erfolgt auf elektrolytischen Wege, wobei ein einwandfreier Stromfluß gewährleistet sein muß. Hierzu werden die Teile auf elektrisch leitenden Gestellen befestigt (gestaffelt), die über Kontaktköpfe an sogenannten Warenschienen angebracht werden. Die Warenschienen mit den daran hängenden, beladenen Gestellen werden, im Laufe des Behandlungsprozesses, mittels Hebe-Fördereinrichtungen in die Bäder ein- und ausgefahren. Die Warenschienen überspannen die Bäder und liegen auf den Wannenrahmen auf.Galvanic systems consist of a number of baths, arranged in an appropriate order, in which parts intended for surface finishing are treated. The treatment is carried out by electrolytic means, whereby a perfect current flow must be guaranteed. For this purpose, the parts are attached (staggered) to electrically conductive frames, which are attached to so-called goods rails via contact heads. During the course of the treatment process, the goods rails with the loaded racks attached to them are moved into and out of the baths by means of lifting conveyor devices. The goods rails span the bathrooms and lie on the tub frame.

Beim galvanischen Prozess wird den zu behandelnten Teilen, durch geeignete Kontakteinrichtungen, über Warenschiene und Gestell elektrische Energie zugeführt. Zur Sicherstellung eines eines einwandfreien Prozessablaufes ist eine gute elektrische Verbindung der Galvanikgestelle mit der Warensrhiene erforderlich.In the galvanic process, the parts to be treated are supplied with electrical energy by means of suitable contact devices, via the goods rail and frame. A good electrical connection between the electroplating frames and the goods rail is required to ensure that the process runs smoothly.

Hierfür werden bisher Kontakköpfe verschiedener Bauart verwendet. Bekannt sind, Schalbenschwanzköpfe die an den Warenschienen befestigt werden und in die dazu passende Gestelle einzuhängen sind, sowie Spannklauen mit Exenterspannung oder Arretierschrauben. Hierfür sind jedoch manuelleUp to now, contact heads of various types have been used for this. Known are dovetail heads which are fastened to the goods rails and which have to be attached to the matching frames, as well as clamping claws with eccentric clamping or locking screws. However, this is manual

Betätigungen erforderlich. Darüber hinaus werden mechanische Kräfte erzeugt, die auch zu Beschädigungen der Warenschienen führen.Operations required. In addition, mechanical forces are generated that also damage the goods rails.

Mit der Erfindung wird erreicht, daß üher Keilwirkung eine kraftschlüssige Verbindung mit der Warenschiene hergestellt wird, ohne die Warenschiene mechanisch zu beanspruchen. So sichert die konvexe Form der Keilspannplattendruckfläche einen ausreichenden Anpressdruck auch bei deformierten Stromschienen. Für die Befestigung genügt eine in Richtung abwärts geführte, vom Beladungsgewicht unterstützte Stoßbewegung. Das Entkontaktieren erfolgt in entgegengesetzter Richtung, nach lösen der Sicherung. In der Größenordnung sind die Kontaktköpfe den bestehenden Einrichtungen anzupassen.With the invention it is achieved that a non-positive connection with the goods rail is established via wedge action without mechanically stressing the goods rail. The convex shape of the wedge clamping plate pressure surface ensures sufficient contact pressure even with deformed busbars. For the attachment, a downward movement supported by the load weight is sufficient. The contact is removed in the opposite direction after the fuse has been removed. The size of the contact heads must be adapted to the existing facilities.

Die mit der Erfindung erzielten Vorteile liegen in einem entsprechenden Rationalisierungseffekt, da der Zeitaufwand für die Betätigung von Spann- und Löseelementen entfällt. Die Gestelle lassen sich stufenlos auf der Warenschiene verschieben. Da keine mechanischen Verletzungen der Warpnschienen auftreten. können die planebenen Kontaktflächen auf lange Zeit erhalten bleiben. Nicht zuletzt sichert die einwandfreie, kraftschlüssige elektrische Kontaktgabe einen Prozessablauf mit geringem Ausschußrisiko.The advantages achieved with the invention lie in a corresponding rationalization effect, since the time required for the actuation of tensioning and releasing elements is eliminated. The frames can be steplessly moved on the goods rail. Since there are no mechanical injuries to the warp rails. the flat contact surfaces can be preserved for a long time. Last but not least, the flawless, non-positive electrical contact ensures a process flow with low risk of rejects.

Die Erfindung wird in der Zeichnung dargestellt und wie folct näher beschrieben:

  • Fig.l zeigt den erfindunnsgenäßen selbstspannenden Kontaktkopf in Ausgangslage, in geöffneter Stellung.
  • Fig.2 zeigt den selbstspannenden Kontaktkopf in Arbeitslage, in geschlossener Stellung mit einnefahrenem Warenbalken.

  • Fig.l shows the inventive self-tensioning contact head in the starting position, in the open position.
  • Fig. 2 shows the self-tensioning contact head in the working position, in the closed position with a retracted goods bar.

ber Kontaktkopf besteht aus dem Grundkörper(l) und einer Keilspannplatte(2) mit vorspringender Mase(3). Die Keilspannplatte(2) wird an ihrer Keilfläche, unter einem Winkel von 2 bis 20°, mittels zwei Führungsstiftep(4) über den Führungsschlitz(5) undVia the contact head consists of the base body (l) and a wedge clamping plate (2) with projecting nose (3). The wedge clamping plate (2) is on its wedge surface, at an angle of 2 to 20 °, by means of two guide pins (4) over the guide slot (5) and

der Gegendruckplatte(6) am Grundkörper(1) geführt. Die Druckfläche(7) der Keilspannplatte(2) ist in Längsrichtung konvex geformt. Durch ihr Eigengewicht befindet sich die Keilspannplatte(2) in ihrer Ausaangslage immer in geöffneter Stellung. Beim Aufsetzen des Kontaktkopfes(1) auf die Warenschiene(8), wird die Keilspannplatte(2) über die Mase(3), durch den Aufsetzdruck nach oben gedrückt und verkeilt so den Kontaktkopf(1) mitthe counter pressure plate (6) on the base body (1). The pressure surface (7) of the wedge clamping plate (2) is convex in the longitudinal direction. Due to its own weight, the wedge clamping plate (2) is always in the open position in its initial position. When the contact head (1) is placed on the goods rail (8), the wedge clamping plate (2) is pressed upwards over the mast (3) by the mounting pressure and thus wedges the contact head (1)

der Warenschiene(8). Das Gewicht der Beladung hat hiebei eine sichernde Wirkung. In Fällen mit extremen Badauftrieb, wird der Kontaktkopf(1) durch den Sicherungsstift(10) gegen ungewolltes lösen gesichert. Dipser Sicherungsstift (10) wird beim Einhängen des Kontaktkopfes(1) automatisch zurückgeschoben und rastet in der Endstellunc· durch Federdruck(9) unter der Warenschiene(8) ein. Zum Abnehmen des Kontatkonfes(1) wird der Sicherungsstift(10) durch betätigen des Zugknopfes(ll) entriegelt. Für die Befestigung der Gestelle am Kontaktkopf(1) ist unterhalb der Sicherungseinrichtung(9)(10)(11) eine Befestigungsvorrichtung(12) vorgesehen. Diese Befestigungsvorrichtung ist, wie in Schnit"A"dargestellt, prismatisch (13) ausgebildet und ermöglicht so die exakte Verbindung von runden, quadratischen oder rechteckigen Gestellquerschnitten.the goods rail (8). The weight of the load has a securing effect. In cases with extreme bath buoyancy, the contact head (1) is secured against unwanted loosening by the locking pin (10). Dipser locking pin (10) is automatically pushed back when the contact head (1) is hooked in and engages in the end position by spring pressure (9) under the goods rail (8). To remove the contact (1), the locking pin (10) is unlocked by pressing the pull button (II). A fastening device (12) is provided below the securing device (9) (10) (11) for fastening the frames to the contact head (1). As shown in section "A", this fastening device is prismatic (13) and thus enables the exact connection of round, square or rectangular frame cross sections.
