Problems solved by technology

The test results obtained by this known device are also very imprecise
In other words, the test results determined by this known device exhibit significant dispersion and imprecision compared with test results obtained by laboratory equipment
The known device is thus less successful in practice

Embodiment Construction

[0031] figure 1 One half of a textile machine 1 (in this embodiment an open-end rotor spinning machine) producing cross-wound bobbins is schematically shown in side view. As known, such textile machines have a plurality of similar workstations 2 between their end frames (not shown). The workstations 2 have, among other things, a spinning unit 3 and a winding mechanism 4 .

[0032] The winding mechanism 4 has, for example, a creel 9 , a bobbin drive roller 11 and a yarn traversing device 16 . In the present example, the bobbin drive roller 11 is acted upon by a drive 13 via a separate motor, which drives the cross-wound bobbins 8 freely rotatably mounted on the creel 9 by means of frictional engagement.

[0033] The fiber strip 6 stored in the spinning pot 5 is processed in the spinning unit 3 into yarns 7 which are then wound onto a winding mechanism 4 to form a cross-wound bobbin 8 . The completed cross-wound bobbins are then transported via a cross-wound bobbin transport ...

Abstract

The invention relates to a textile machine that produces cross-wound bobbins, comprising a device, which is arranged on an operating unit and which serves to test the quality of a yarn or yarn piecings produced at one of the spinning locations of the textile machine. The operating unit has a tensile testing device as well as a device for transferring a yarn to the tensile testing device. The invention provides that the tensile testing device (15) has a measuring section (19) of a predetermined length. Yarn clamps (20, 21) are placed at the end of the measuring section (19). The first yarn clamp (20) is displaceably mounted and can be acted upon in a defined manner by a drive (22). A sensor device (23) is placed in the area of the measuring section (19). Both the drive (22) as well as the sensor device (23) are connected to a control device (25). The control device is part of the operating unit (18), and is connected via a machine bus (26) to a central control unit (27) of the textile machine (1).

Description

technical field [0001] The invention relates to a textile machine for producing cross-wound bobbins. Background technique [0002] With regard to textile machines producing cross-wound bobbins, it has long been known that the running yarn should be monitored for yarn defects. However, the so far possible monitoring of yarns during production is limited to the possibility of optical or capacitive analysis (slub position, thin position, spots, fuzz, diameter, outer fibers, etc.). Other important parameters, such as yarn tear resistance, yarn elongation, yarn titer, yarn rotation, etc., have hitherto usually been monitored in a laboratory. In such cases, monitoring is usually carried out at the start of series production and at irregular time intervals thereafter. For monitoring, the bobbin must first be removed from the winding device of the textile machine, inspected and possibly returned to the textile machine later. Because of this relatively cumbersome approach, the num...
