Problems solved by technology

Therefore, as the number of stations increases, the discrepancy between the actual station positions and the station positions indicated by the possible positioning rails can increase significantly
In addition, mechanical vibrations may occur due to resonance during operation of the textile machine, which can cause shifting of the station units
This is especially troublesome when positioning the service unit in front of the work station that needs to be operated

Embodiment Construction

[0033]exist figure 1 An open-end spinning machine 1 is shown in , which has a plurality of stations 2 each of which is equipped with an open-end spinning device 3 and a winding device 4 . The open-end spinning machine 1 also has two identical service groups 16 .

[0034] In the spinning device 3, the fiber sliver fed into the spinning drum 5 is spun into a yarn, which is drawn out of the spinning device 3 by means of a delivery roller pair 18 and wound up on the winding device 4 Wind the bobbin 8 into a cross. Winding device 4 such as figure 2 Shown is equipped with a creel 9 for rotatably holding an empty bobbin 11 or cross-wound bobbin 8 and a winding drum 25 for rotating the empty bobbin 11 or cross-wound bobbin 8 . The open-end spinning machine 1 also has a central control unit 6 which is connected via a bus system 26 to the control unit 10 of the workstation itself. In addition, such a textile machine 1 has a cross-wound bobbin delivery device 12 for handling complet...

Abstract

The invention relates to a textile machine (1) having a work station (2) for making cross-wound bobbins and a method of operating such textile machine. The textile machine (1) comprises a work station unit (42) of a plurality of functional elements (3,9,18,19,20,25,40) having the work station (2), a machine frame (7) for holding the work station unit, a service unit (16) moved along the machine frame (7) for work station operation, an electric measurement body (45) fixed on the work statin unit (42), and measuring coils arranged on the service unit, wherein, the measuring coils (50,51,52) and the measuring body (45) are configured and formed in such manner: namely, an impedance of the measuring coils (50,51,52) changes because of an eddy current formed in the measuring body (45) when the service unit (16) is close to the work station (2). The textile machine also comprises an analytical device (60), and parameters effected by the impedance of the measuring coils (50,51,52) can be obtained by virtue of the analytical device.

Description

technical field [0001] The invention relates to a textile machine for the manufacture of cross-wound bobbins, having a plurality of work stations and a service unit movable along the machine for handling the work stations. The invention likewise relates to a method for operating a textile machine, in particular for determining the position of the service unit within the textile machine and for positioning the service unit in front of a work station required for use. Background technique [0002] DE3841464A1 discloses a textile machine with a movable service unit. Both the service unit and the work stations are equipped with antennas, preferably in the form of coils with ferrite cores. The station's antenna, when necessary, sends out a signal that the station needs to be operated. This signal can be picked up by the antenna of the patrolling service crew. Using the antenna, the service group can then also be positioned in front of the workstation as required. When the ser...
