Method for monitoring the correct operation of the spinning stations of a ring spinning machine

Abstract

The invention relates to a method for monitoring the correct operation of spinning stations of a ring spinning machine. It also relates to related devices, including the spinning stations (8) that allow the spinning packages (13) to be identified so that they can be assigned to the ring spinning machine (1) at any time ) and the sensor device of the winding station (16) of the cross-winding bobbin winder (2) arranged downstream, which monitors the spinning bobbin (13) during the subsequent rewinding process of yarn (56). The advancing yarn (56) of the spinning bobbin (13) is scanned by a sensor device designed as a yarn tensile strength sensor (67), and the yarn tension data determined by the yarn tensile strength sensor (67) is sent to The winding station computer (54) of the associated winding station (16) for processing wherein yarn tension data of spinning bobbins (13) above a predetermined threshold and thus representing hard winding are indicated to be problematic, subsequently This yarn tension data is distributed to the spinning stations (8) of the ring spinning machine (1) that manufacture the associated spinning packages (13).

Description

technical field [0001] The present invention relates to a method and a device for monitoring the correct functioning of a plurality of spinning stations of a ring spinning machine during the manufacture of spinning packages, the device comprising allowing the identification of spinning packages so that they can be assigned at any time to The device of the spinning station of the ring spinning machine where the spinning package is produced and the sensor device arranged downstream at the winding station of the cross-winding bobbin Monitoring of the yarn in the spinning package during the process. Background technique [0002] It is known that, during the manufacture of spinning packages, the yarn is always prepared directly at the spinning station of the ring spinning machine only when the yarn is wound onto the spinning package. At such spinning stations, direct yarn quality control is therefore almost impossible to perform. This means that in known ring spinning machines ...

Problems solved by technology

[0024] But the shortcoming of above-mentioned known method or device is, by means of the latter can only find those spinning stations of the ring spinning machine, also produce unusable yarn for a prolonged period of time
