Abstract
Description
Die Erfindung betrifft einen Kettenglied für eine Schleppkette, umfassend zwei längliche Seitenelemente, die ihren Längsenden benachbart mit Verbindungsmitteln ausgebildet sind, welche die, vorzugsweise gelenkige, Verbindung des Kettenglieds mit einem identisch ausgebildeten Kettenglied erlauben, und zwei Verbindungsstege, von denen jeder einen Längsrand eines der Seitenelemente mit einem Längsrand des jeweils anderen Seitenelements verbindet.The invention relates to a chain link for a drag chain, comprising two elongate side members which are formed adjacent their longitudinal ends with connecting means which allow the, preferably articulated, connection of the chain link with an identically shaped chain link, and two connecting webs, each of which has a longitudinal edge of one of Side elements connects with a longitudinal edge of the other side element.
Schleppketten und damit auch Kettenglieder für derartige Schleppketten sind im Stand der Technik allgemein bekannt. Sie werden beispielsweise zur Führung von Kabeln, beispielsweise Stromversorgungskabeln und Steuerungskabeln, insbesondere Datenübertragungskabeln, eingesetzt, die zwischen einem beweglichen Maschinenteil und einem ortsfestem Maschinenteil verlaufen. Nachteilig an den bekannten Schleppketten ist, dass die zu von diesen zu führenden Kabel aufwändig in den von den Seitenelementen und den Verbindungsstegen gebildeten lichten Durchgang der Schleppketten eingefädelt werden müssen.Drag chains and thus chain links for such drag chains are well known in the art. They are used, for example, to guide cables, for example power supply cables and control cables, in particular data transmission cables, which run between a movable machine part and a stationary machine part. A disadvantage of the known drag chains that must be threaded to the leading of these cables consuming in the light passage formed by the side members and the connecting webs of the drag chains.
Demgegenüber ist es Aufgabe der vorliegenden Erfindung, ein Kettengleid für eine Schleppkette und eine aus einer Mehrzahl derartiger Kettenglieder zusammengesetzte Schleppkette anzugeben, bei welchen das Einführen der Kabel erleichtert ist.In contrast, it is an object of the present invention to provide a chain link for a drag chain and a composite of a plurality of such chain links drag chain, in which the insertion of the cable is facilitated.
Erfindungsgemäß wird diese Aufgabe durch ein Kettenglied der eingangs genannten Art gelöst, bei welchem ein erster der Verbindungsstege mit einem Filmscharnier ausgebildet ist, während ein zweiter der Verbindungsstege zwei Teilstege umfasst, die mittels Befestigungsmitteln aneinander befestigbar sind. Erfindungsgemäß kann eine Schleppkette aus einer Mehrzahl derartiger Kettenglieder im geöffneten Zustand der Befestigungsmittel zusammengesetzt werden. Anschließend können die Kabel in die Schleppkette eingelegt werden. Und schließlich kann die Schleppkette unter Ausnutzung der Filmscharniere zusammengeklappt und durch Schließen der Befestigungsmittel in den betriebsbereiten Zustand übergeführt werden.According to the invention this object is achieved by a chain link of the type mentioned, in which a first of the connecting webs is formed with a film hinge, while a second of the connecting webs comprises two partial webs, which are fastened to each other by means of fastening means. According to the invention, a drag chain can be composed of a plurality of such chain links in the opened state of the fastening means. Then the cables can be inserted into the drag chain. And finally, the drag chain can be folded using the film hinges and transferred by closing the fasteners in the ready state.
Zur Erleichterung der Herstellung der Kettenglieder können diese einstückig ausgebildet, vorzugsweise spritzgegossen, sein. Dabei ist zu berücksichtigen, dass, obgleich der zweite Verbindungssteg zweiteilig ausgebildet ist, seine beiden Teile doch über die beiden Seitenelemente und den ersten Verbindungssteg einstückig miteinander verbunden sind.To facilitate the production of the chain links, these can be integrally formed, preferably injection-molded, be. It should be noted that, although the second connecting web is formed in two parts, but its two parts are connected via the two side members and the first connecting web integrally with each other.
Beispielsweise können die Kettenglieder aus Polypropylen oder Polyamid, beispielsweise PA6, hergestellt sein, wobei diese Materialien auch glasfaserverstärkt sein können.For example, the chain links may be made of polypropylene or polyamide, for example PA6, which may also be glass fiber reinforced.
Um ein unbeabsichtigtes Öffnen der Schleppkette oder einzelner Glieder der Schleppkette verhindern zu können, wird vorgeschlagen, dass die Befestigungsmittel unlösbar sind. Das bedeutet, dass die Befestigungsmittel dann, wenn sie einmal geschlossen worden sind, nur noch unter Zerstörung der Befestigungsmittel wieder geöffnet werden können. Die Befestigungsmittel können beispielsweise von Rastmitteln gebildet sein.In order to prevent unintentional opening of the drag chain or individual members of the drag chain, it is proposed that the fastening means are insoluble. This means that once the fasteners have been closed, they can only be reopened by destroying the fasteners. The fastening means may be formed for example by locking means.
Zur Vereinfachung der Handhabung beim Einlegen der Kabel und Schließen der Schleppkette wird ferner vorgeschlagen, dass das Filmscharnier oder/und die Befestigungsmittel etwa in der Mitte der Längserstreckung des jeweiligen Verbindungsstegs angeordnet sind.To simplify the handling when inserting the cable and closing the drag chain is also proposed that the film hinge and / or the fastening means are arranged approximately in the middle of the longitudinal extension of the respective connecting web.
Wie vorstehend bereits angedeutet worden ist, betrifft die Erfindung ferner eine aus derartigen Kettengliedern gebildete Schleppkette und ein Verfahren zur Montage einer derartigen Schleppkette.As already indicated above, the invention further relates to a drag chain formed from such chain links and a method for assembling such a drag chain.
Die Erfindung wird im Folgenden anhand der beigefügten Zeichnungen an einem Ausführungsbeispiel näher erläutert werden. Es stellt dar:The invention will be explained in more detail below with reference to the accompanying drawings of an exemplary embodiment. It shows:
