Abstract (en)
The open-end spinner has a sliver loosening unit (4) in an easily-released mounting at the connecting bracket (30) of its straight guide (3), at the spinning box housing (2). A sliver loosening roller (12), to break the sliver down into fibers, is within the sliver loosening unit with its own motor together with the sliver take-in cylinder (14) powered by a step motor (15). The sliver loosening unit is mounted to pivot on a swing axis in a guide slit at the mounting bracket, which is open to the front, held in place by a sprung locking bolt which slides within a drilling at the sliver loosening unit body. A second straight guide (70) is at the mounting bracket, with guide bolts (63) which fit into guide drillings (69) at the mounting body (71) of the sliver loosening unit. At least one guide bolt has a locking groove (66), to be engaged by manual locking levers (64) riding in vertical guide slits (65) near the guide drillings at the mounting body. A spring at the locking lever holds it in the engaged position. An electromotor (13) with an outer rotor drives the sliver loosening roller. A coupling plate (34) links the power supply lines (35-38) at the mounting bracket, working with a coupling (45) at the sliver loosening unit. A centering unit (46) is between the mounting bracket and the bearing pedestal (26) at the bearing assembly (5) for the spinning rotor, with at least one centering component (47) as a key holder. A static funnel (39) to catch dirt, and its pneumatic waste disposal system (40), are located under the sliver loosening unit. The spinning rotor (7) is powered by a single electromotor drive (6). The axis (48) of the sliver loosening roller and the axis (49) of the sliver take-in roller are orthogonal to the axis (50) of the spinning rotor.
Abstract (de)
Die Erfindung betrifft eine Offenend-Spinnvorrichtung (1) mit einem am Maschinengrundrahmen einer Textilmaschine angeordneten, stationären Spinnboxgehäuse (2) zur Lagerung eines mit hoher Drehzahl in einem unterdruckbeaufschlagbaren Rotorgehäuse (8) umlaufenden Spinnrotors (7), einer über eine Linearführung (3) an das Spinnboxgehäuse (2) angeschlossenen Faserband-Auflöseeinheit (4) sowie einem Deckelelement (23) zum Verschließen des Rotorgehäuses (8). Erfindungsgemäß ist vorgesehen, daß die Faserband-Auflöseeinheit (4), bei Bedarf leicht lösbar, an eine Anschlußkonsole (30) der Linearführung (3) angeschlossen ist und daß innerhalb der Faserband-Auflöseeinheit (4) eine einzelmotorisch antreibbare Auflösewalze (12) sowie ein durch einen Schrittmotor (15) angetriebener Faserband-Einzugszylinder (14) angeordnet sind. <IMAGE>
