Workstation of a textile machine for creating cross-wound spools

Abstract

The invention relates to a workstation of a textile machine for creating cross-wound spools, comprising a thread receiving mechanism disposed within an unwinding region of a feeding spool, thread monitoring and treatment mechanisms mounted within a thread passageway region and a winding device for creating a cross-wound spool. According to the invention, the workstation (1) has a thread guidance channel (6) that encloses a thread passageway, is composed of multiple portions and has receptacle housings (18, 21) or receiving portions (31, 32, 33) for various thread monitoring and treatment mechanisms. The thread guidance channel (6) is extended between a feeding spool (2) at an unwinding position (AS) and a winding device (4) and can be locally applied with negative pressure according to the need, so that the negative pressure flow is present in the thread guidance channel (6) and the flow direction can be determined as desired.

Description

technical field [0001] The invention relates to a station of a textile machine for producing cross-wound bobbins according to the preamble of claim 1 . Background technique [0002] At the station of a textile machine that manufactures cross-wound bobbins, bobbins fed to bobbins such as those produced on ring spinning machines and having relatively little yarn material are rewound into cross-wound bobbins with a greater amount of yarn. Wind the bobbin. The workstations of such textile machines are in particular described in DE 10 2005 001 093 A1, with various yarn monitoring and handling mechanisms in the yarn travel area, whereby the yarn moving during the rewinding process is monitored, e.g. Whether there may be yarn defects. If yarn faults above a certain threshold are found, they are cut off and replaced by almost identical yarn connections, mostly pneumatically produced, so-called yarn splices. Furthermore, the individual stations each have a winding device with a cr...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned stations of textile machines for producing cross-wound bobbins have been confirmed in practice in principle, but they have the following disadvantages: Although the use of tubular yarn guides and dust removal mechanisms positioned in the area of ​​the bobbins is not sufficient, the Reliable protection of the workplace from contamination by dust particles and flying flowers over time

In addition, the construction of these workstations is relatively wide, because in particular the suction nozzles and clamping tubes for the yarn handling mechanism (which, for example, as described above, are put into use after the winding interruption, in order to send the end of the yarn to the yarn The drive device of the thread splicing mechanism) is quite heavy in structure, which has caused the mutual spacing of the stations arranged side by side of the textile machine to be relatively large
