Yarn deflection roller for mechanical yarn energy accumulator

Abstract

The invention relates to a yarn deflection roller (39) for a mechanical yarn energy accumulator (4). The yarn deflection roller (39) is arranged in an area of a yarn traversing cam (9) of a workstation (10) of a textile machine that manufactures a cross-wound bobbin, and changes in yarn winding speed due to yarn traversing during winding of the cross-wound bobbin (19) via the yarn deflection roller (39) can be compensated. According to the invention, the yarn deflection roller (39) is provided with a yarn running surface (7) in which a U-shaped yarn guide groove (32) is processed.

Description

technical field

[0001] The invention relates to a yarn deflecting roller for a mechanical yarn accumulator, which is arranged in the region of the yarn traversing triangle of a workstation for manufacturing cross-wound bobbins of a textile machine, through which the yarn The deflection rollers compensate for changes in the yarn winding speed due to yarn traversing during the winding of the cross-wound package. Background technique

[0002] As already known, the workstation for producing cross-wound bobbins of a textile machine configured as an open-end rotor spinning machine has: an open-end rotor spinning device, each open-end rotor spinning device Both produce yarn at a constant delivery speed; a winding device, which ensures that: the produced yarn is wound on a winding spindle and traversed simultaneously to create a cross-wound bobbin; and a yarn accumulator, The yarn accumulator compensates for yarn winding speed and yarn tension fluctuations due to yarn traversing. ...

Embodiment Construction

[0038] figure 1 A perspective elevational view of a highly schematic type is provided showing a workstation 10 of a textile machine (in the present example an open-end rotor spinning machine) producing cross-wound bobbins. As already disclosed, such an open-end rotor spinning machine has a large number of identically configured workstations 10 of this type, which are arranged next to each other in a row. At the workstation 10, a yarn 17 is spun in each case by means of an open-end rotor spinning device 12 from a so-called sliver held in a spinning pot (not shown) and subsequently in a winding device 18. The yarn 17 is wound into a cross-wound bobbin 19.

[0039]The winding devices 18 of such workstations 10 each have: a creel 8 for holding cross-wound bobbins 19 in a rotating arrangement; a yarn traversing device 22 with a traversing yarn guide 1 which For example, it may be driven by a single motor for traversing the yarn 17 running onto the cross-wound bobbin 1; and a bobb...
