Abstract

Eine Fachbildeeinrichtung (1) für eine Webmaschine weist mehrere Webschäfte auf, denen eine Antriebseinrichtung mit mehreren Servomotorgruppen (13, 14) zugeordnet ist. Die Servomotorgruppen sind unterhalb der Webschäfte (3 bis 8) jeweils als Cluster angeordnet, wobei sie mit ihren Drehachsen (27 bis 32) auf einem Kreis, einer Ellipse oder einer ähnlichen Figur angeordnet sind. Außerdem sind sie axial gegeneinander versetzt. Jeder Servomotor (15 bis 20) ist mit einem Abtriebshebel (21 bis 26) versehen. Die freien Enden aller Hebel stehen etwa im Zentrum des Kreises oder der Ellipse oder der sonstigen Umlauffigur. Sie sind über Pleuel (34 bis 39) mit den Webschäften (3 bis 8) verbunden, wobei sie mit den Pleueln (34 bis 39) unterschiedliche Winkel einschließen. Es ergibt sich dadurch eine Antriebseinrichtung mit geringer Trägheit, geringer Nachgiebigkeit und geringem Spiel. Es ist die kontrollierte Erzielung sehr schneller Schaftbewegungen möglich.

A shedding device (1) for a weaving machine has a plurality of heald frames, to which a drive device having a plurality of servomotor groups (13, 14) is assigned. The servomotor groups are arranged below the heald frames (3 to 8) in each case as a cluster, wherein they are arranged with their axes of rotation (27 to 32) on a circle, an ellipse or a similar figure. In addition, they are axially offset from each other. Each servomotor (15 to 20) is provided with a driven lever (21 to 26). The free ends of all levers are approximately in the center of the circle or the ellipse or other circulating figure. They are connected by connecting rods (34 to 39) with the Webschäften (3 to 8), wherein they include different angles with the connecting rods (34 to 39). This results in a drive device with low inertia, low compliance and low clearance. It is the controlled achievement of very fast shaft movements possible.
