Description

Gegenstand des Hauptpatentes ..................... (P 29 23 890. 2-21) ist eine Kupplungsvorrichtung für sogenannte Power and Free-Schleppkreisförderer, die zum An- und Abkuppeln von auf einer Hängebahn verfahrbaren Förderwagen dient. Die bekannte Kupplungsvorrichtung besteht aus zwei Kupplungsbacken, die auf einer an der Schleppeinrichtung befindlichen, parallel zu einer Hängebahn verlaufenden Achse gegensinnig quer zur Förderrichtung schwenkbeweglich gelagert sind. Gegenstand der Erfindung sind weitere Verbesserungen an der bekannten Kupplungsvorrichtung, mit dem Ziel, eine noch größere Betriebssicherheit und Laufruhe zu erreichen. So soll durch die Anordnung eines Anschlagkörpers auf der die Kupplungsbacken tragenden Achse eine einseitige Begrenzung, der Schwenkbewegungen der Kupplungsbacken erreicht werden, um zu verhindern, daß die Kupplungsvorrichtung bei starken seitlichen Pendelbewegungen des Förderwagens unkontrolliert auskuppelt. Zum anderen sollen durch eine verbesserte Ausbildung der Kupplungsbacken die Geräusche während des Betriebes, besonders beim An- und Abkuppeln, noch stärker unterdrückt werden.The subject of the main patent ..................... (P 29 23 890. 2-21) is a coupling device for so-called power and free drag chain conveyors, which are used to connect and Uncoupling of trolleys movable on a monorail. The known coupling device consists of two coupling jaws which are pivotally mounted on an axis located on the towing device and running parallel to a monorail in opposite directions transversely to the conveying direction. The invention relates to further improvements to the known coupling device, with the aim of achieving even greater operational reliability and smoothness. Thus, by arranging a stop body on the axis carrying the coupling jaws, a one-sided limitation of the pivoting movements of the coupling jaws is to be achieved in order to prevent the coupling device from uncontrollably disengaging in the event of strong lateral pendulum movements of the trolley. On the other hand, through an improved design of the clutch shoes, the noise during operation, especially when coupling and uncoupling, is to be suppressed even more.

Die kennzeichnenden Merkmale der Erfindung sind in den Ansprüchen niedergelegt. Ein Ausführungsbeispiel ist nachstehend anhand der Zeichnungen beschrieben.

  • Fig.1 zeigt eine erfindungsgemäße Kupplungsvorrichtung im Längsschnitt,
  • Fig. 2 im Querschnitt nach der Linie II - II in Fig. 1 und
  • Fig. 3 in Draufsicht.
The characteristic features of the invention are laid down in the claims. An embodiment is described below with reference to the drawings.
  • 1 shows a coupling device according to the invention in longitudinal section,
  • Fig. 2 in cross section along the line II - II in Fig. 1 and
  • Fig. 3 in top view.

Mit strichpunktierten Linien ist in Fig. 1 eine bekannte Schleppkette angedeutet, die mittels Trag- und Stützrollen in einem Kettenkanal geführt ist. Mit der Schleppkette ist das Gehäuse 1 der Kupplungsvorrichtung an seinen beiden Enden über Winkellaschen verbunden. Das aus Blech geformte Gehäuse 1 weist zwei durch Umbiegen von Lappen des Gehäusezuschnittes gebildete Doppelquerwände 2 und 3 auf, in denen eine die beiden Kupplungsbacken 4 und 5 tragende Achse 6 aufgenommen ist.1, a known drag chain is indicated by dash-dotted lines, which is guided in a chain channel by means of support and support rollers. With the drag chain, the housing 1 of the coupling device is connected at its two ends via angle brackets. The housing 1 formed from sheet metal has two double transverse walls 2 and 3 formed by bending flaps of the housing blank, in which an axis 6 carrying the two coupling jaws 4 and 5 is received.

Die Kupplungsbacken 4 und 5 sind identische Spritzgußformkörper aus einem Werkstoff mit guten Gleit- und Geräuschdämpfungseigenschaften. An ihren beiden Enden weisen die Kupplungsbacken von unten nach oben. verlaufende Schrägkanten 7, 7' und im mittleren Bereich eine nach unten offene Ausnehmung 8 auf. Die Innenwände der beiden Kupplungsbacken 4 und 5 sind in den Abschnitten zwischen der Ausnehmung 8 und den Schrägkanten 7 bzw. 7 mit parallelen Längsrippen 9, 9 - versehen, die versetzt zueinander angeordnet sind, so daß sie ineinandergreifen können. Als zusätzliche Maßnahme zur Geräuschminderung sind im Bereich der Rippen 9, 9 in den Wandungen der Kupplungsbacken 4 und 5 kleine Gummipuffer 10 vorgesehen.The clutch shoes 4 and 5 are identical injection molded articles made of a material with good sliding and noise damping properties. At both ends, the clutch shoes face upwards. running inclined edges 7, 7 'and in the middle area a downwardly open recess 8. The inner walls of the two clutch shoes 4 and 5 are in the sections between the recess 8 and the inclined edges 7 and 7 with parallel longitudinal ribs 9, 9 - provided, which are arranged offset from one another so that they can interlock. As an additional measure to reduce noise, small rubber buffers 10 are provided in the area of the ribs 9, 9 in the walls of the clutch shoes 4 and 5.

Die Kupplungsbacken 4 und 5 sind mit angeformten Lageraugen 11 und 12 auf der Achse 6 gelagert, die außerdem noch einen Anschlagkörper 13 trägt, der aus einer auf der Achse 6 mittels eines Spannstiftes 14 befestigten Büchse 15 mit angeformten Fahnen 16 und 17 besteht. Die nach oben gerichteten Fahnen 16 greifen in passende Öffnungen des Gehäusebodens 1' ein und die nach unten gerichteten Fahnen 17 ragen zwischen die Innenwände der Kupplungsbacken 4 und 5. Der Anschlagkörper 13 verhindert auf diese Weise, daß die beiden Kupplungsbacken gemeinsam über die Mittelstellung hinaus nach der einen oder der anderen Seite schwenken können, während das seitliche Ausschwenken jeder einzelnen Kupplungsbacke 4 bzw. 5 durch den Anschlagkörper 13 nicht behindert wird. Verhindert wird demzufolge nur, daß die Kupplungsvorrichtung unter dem Einfluß starker Pendelbewegungen eines geschleppten Förderwagens, dessen Kupplungsglied Fk mit strichpunktierten Linien in Fig. 1 und 2 angedeutet ist, seitlich versetzt wird, weil dadurch das Kupplungsglied des geschleppten Förderwagens möglicherweise aus der von den Ausnehmungen 8 der Kupplungsbacken gebildeten Tasche auskuppeln könnte.The coupling jaws 4 and 5 are mounted with molded bearing eyes 11 and 12 on the axis 6, which also carries a stop body 13, which consists of a bush 15 fastened on the axis 6 by means of a dowel pin 14 with molded flags 16 and 17. The upward-facing lugs 16 engage in suitable openings in the housing base 1 'and the downward-facing lugs 17 protrude between the inner walls of the coupling jaws 4 and 5. The stop body 13 thus prevents the two coupling jaws from moving together beyond the central position one or the other side can pivot, while the lateral pivoting out of each clutch shoe 4 or 5 is not hindered by the stop body 13. It is consequently only prevented that the coupling device is displaced laterally under the influence of strong pendulum movements of a towed trolley, the coupling member Fk of which is indicated by dash-dotted lines in FIGS the clutch shoe formed pocket could disengage.
