Die Erfindung betrifft eine Kupplungsvorrichtung für Textilmaschinen gemäss dem Oberbegriff des Anspruches l sowie eine Schaftmaschine mit einer derartigen Vorrichtung.The invention relates to a coupling device for textile machines according to the preamble of claim 1 and a dobby with such a device.

Bekannte Vorrichtungen dieser Art weisen eine Exzenterscheibe, die auf einer Hauptwelle gleitbar bzw. drehbar angeordnet ist, einen Pleuel, der auf derKnown devices of this type have an eccentric disc which is slidably or rotatably arranged on a main shaft, a connecting rod which on the

Exzenterscheibe gelagert ist, eine Klinke, die an der Exzenterscheibe schwenkbar angeordnet ist und eine Einrichtung zum Betätigen der Klinke auf, die eine Mehrzahl von mechanischen Elementen umfasst. Ferner ist eine Arretierungseinrichtung vorgesehen, um die Klinke im eingekuppelten Zustand zu sichern. Hierzu werden ebenfalls mehrere mechanische Elemente benötigt.Eccentric disc is mounted, a pawl which is pivotally arranged on the eccentric disc and a device for actuating the pawl, which comprises a plurality of mechanical elements. Furthermore, a locking device is provided to secure the pawl in the engaged state. Several mechanical elements are also required for this.

Da die Schaltzeiten bei der Kupplungsvorrichtung sehr kurz sind, werden die Elemente, welche zum Teil grosse Massen aufweisen extrem beschleunigt bzw. verzögert.Since the switching times in the coupling device are very short, the elements, some of which have large masses, are extremely accelerated or decelerated.

Dadurch wird ein hoher Energiebedarf für die Betätigung der Elemente erforderlich, was einen hohen Verschleiss, sowie Härme- und Lärmentwicklung zur Folge hat. Dadurch wird die Arbeitsgeschwindigkeit im Dauerbetrieb beschränkt. Der Erfindung liegt die Aufgabe zugrunde, eine Kupplungsvorrichtung für Textilmaschinen zu schaffen, welche die genannten Nachteile nicht aufweist.As a result, a high energy requirement is required for the actuation of the elements, which results in high wear and tear, as well as heat and noise. This limits the working speed in continuous operation. The invention has for its object to provide a coupling device for textile machines, which does not have the disadvantages mentioned.

Diese Aufgabe wird erfindungsgemäss mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention with the characterizing features of claim 1.

Dadurch wird die Klinke durch die Einrichtung positiv in die jeweilige Stellung gebracht und gehalten, wodurch eine Fehlfunktion derThe device and the pawl are arranged in close proximity to one another on the eccentric disc and are directly connected to one another. As a result, the pawl is positively brought into the respective position and held by the device, causing a malfunction of the

Kupplungsvorrichtung verhindert und die Schaltphase der Kupplungsvorrichtung verkürzt wird. Mit der kürzeren Schaltphase lassen sich kürzere Stillstandzeiten der Schaftmaschine realisieren, was eine höhere Arbeitsgeschwindigkeit zur Folge hat.Coupling device prevented and the switching phase of the coupling device is shortened. With the shorter switching phase, shorter standstill times of the dobby can be realized, which results in a higher working speed.

Nachfolgend wird die Erfindung anhand der beiliegenden Zeichnungen erläutert.The invention is explained below with reference to the accompanying drawings.
