Embodiment Construction

[0031]figure 1 The semi-automatic open-end rotor spinning machine 1 shown in has a plurality of stations 2 which are each equipped with a spinning device 3 and a winding mechanism 33 . The fiber strip 34 provided in the spinning drum 28 is correspondingly spun into a yarn 30 in the spinning device 3 , and the yarn 30 is subsequently wound into a cross-wound bobbin 22 on a winding device 33 .

[0032] Here, the winding mechanism 33 respectively has: a creel 21 for rotatably holding the sleeve of the cross-wound bobbin 22; bobbin drive roller 23; Lifting mechanism 7 for cross-winding bobbin 22. The lifting mechanism 7 is configured as a thrust piston drive and is connected to a (not shown) overpressure source, for example via a pneumatic line 24 in which a solenoid valve 17 is connected. Furthermore (not shown) a braking mechanism (not shown) is arranged in the region of the winding mechanism 33 , by means of which, if necessary, free rotation of the cross-wound bobbin 22 lifte...

Abstract

The invention relates to a method and device for operating a free end rotor spinner which comprises a plurality of work stations having a spinning device for producing yarns and a winding device for producing a cross winding bobbin, wherein the free end rotor spinner comprises a central control unit and a negative pressure system for the spinner, the negative system also comprises a second negative pressure source which can be turned on when needed besides a main negative pressure source. In the station region, a yarn storage spout subjected with negative pressure for receiving a yarn quantity required in connection with a spinning process and a suction nozzle subjected with the negative pressure which is used during a cross coil / empty case replacement are respectively arranged. According to the invention, the second negative pressure source (42) is arranged to be automatic turn-on as occasion requires.

Description

technical field [0001] The invention relates to a method for operating an open-end rotor spinning machine according to the preamble of the first aspect and a device according to the fifth aspect. Background technique [0002] Open-end rotor spinning machines with a plurality of workstations of the same type, a central control unit and a vacuum system specific to the textile machine are known in various, sometimes very different, embodiments and are described exhaustively in the patent literature. [0003] On the stations of such a textile machine, the fiber strips provided preferably in the spinning drums are spun into yarns by means of an open-end spinning device, and the yarns are then wound into cross-wound bobbins on a winding device. However, there are sometimes considerable differences between the various open-end rotor spinning machines in terms of their design structure and their mode of operation. [0004] For example, DE 198 36 065 A1 discloses an open-end rotor s...
