Yarn clearer and spinning station, equipped therewith, of a spinning machine, and method for operating a spinning station
10246292 · 2019-04-02 · ·

The invention relates to a spinning station (1) of a spinning machine, wherein the spinning station (1) has a spinning means (2) for producing a yarn (3) from a sliver (4) fed to the spinning means (2), wherein the spinning station (1) has a winding apparatus (20) for winding the yarn (3) onto a package (16), said winding apparatus (20) being arranged downstream of the spinning means (2) in a transport direction of the yarn (3), wherein the spinning station (1) has a yarn clearer (5) arranged between the spinning means (2) and the winding apparatus (20), the yarn being monitorable for yarn defects with the aid of said yarn clearer (5), and wherein the spinning station (1) is assigned a controller (6) which is configured to interrupt the production of the yarn (3) if a defined yarn defect is detected. The invention proposes that the spinning station (1) has an information unit (7) with the aid of which it is possible to display to an operator of the spinning station (1) how much yarn (3) has to be at least unwound from the package (16) located in the winding apparatus (20) following the interruption to the yarn production in order to ensure that the yarn section having the yarn defect has been completely removed from the package (16). Furthermore, a yarn clearer and a method for operating a spinning station are proposed.

Optimizing a spinning process with respect to foreign materials

The invention relates to a method for optimizing a spinning process, through which a fiber material fed in the form of raw fibers and output in the form of yarn passes, with respect to foreign materials. At a first position in the spinning process, a first foreign material information relating to the foreign materials is determined. At a second position in the spinning process, which is downstream with respect to the first position, a second foreign material information relating to the foreign materials is determined. The first foreign material information and the second foreign material information are associated with each other such that they relate to substantially the same sample of the fiber material. Based on the first foreign material information and the second foreign material information assigned thereto, a change is made to the spinning process to optimize the spinning process.

Method of adjustment of a workstation and a yarn clearer (yarn quality sensor) on a yarn manufacturing textile machine
10197548 · 2019-02-05 · ·

A method is provided for adjustment of a textile machine workstation based on yarn parameters measured by an associated yarn quality sensor at the work station. The method generates a first reference value of a selected yarn parameter by measurement of the yarn parameter or by calculation, wherein the first reference value is generated from the yarn parameter for a deliberately defective yarn intentionally produced at the workstation. The method then compares a current value or second reference value of the yarn parameter for yarn produced at the workstation of production quality or higher-than-production quality to the first reference value.

Optimizing a yarn production process with respect to foreign materials

The invention relates to a method for optimizing a yarn production process in which foreign materials (90) are monitored in a textile fiber formation (9). The textile fiber formation (9) is illuminated with electromagnetic radiation from at least two color ranges. The foreign materials (90) are classified into different color classes according to their colors. If a sufficiently large random sample with classified foreign materials (90) is available, a frequency distribution of the foreign materials is determined for the color classes and compared with a reference frequency distribution. If the determined frequency distribution deviates from the reference frequency distribution, at least one of a set of multiple optimization actions is performed, e.g., a warning signal is output.

Air jet spinning machine and method for operating the same

A method for operating an air jet spinning machine having at least one spinning unit with one spinning nozzle for producing a yarn is provided. During the operation of the spinning unit, the spinning nozzle feeds a fiber composite through an inlet in a predefined transport direction. The fiber composite within a vortex chamber of the spinning nozzle receives a twist with the assistance of a vortex air flow, such that a yarn is formed from the fiber composite. With the assistance of at least one sensor system, the yarn leaving the outlet is monitored with regard to defined yarn flaws. The production of yarn is interrupted upon the detection of a corresponding yarn flaw. Between the detection of the specified yarn flaw and the interruption of the yarn production, a cleaning process is carried out during which an additive is fed to the spinning unit and is applied to the fiber composite and/or the yarn produced from the fiber composite and/or on parts of the spinning nozzle.
