Embodiment Construction

[0036] figure 1 The basic structure of the spinning machine of the present invention, such as a rotor or an air-jet spinning machine, is shown.

[0037] Spinning machines generally comprise a plurality of spinning units 3 arranged adjacently and / or in tandem (for clarity, image 3 Only three are shown). Each spinning unit 3 is supplied with fiber composite material 13 during the spinning operation, for example via a corresponding spinning pot 21 . The fiber composite material 13 is withdrawn from each spinning pot 21 by a conveying device 5 and then supplied to the spinning station 4 in which the fiber composite material 13 is rotated so that the desired yarn 7 is produced. Yarn 7 is wound up to by winding device 8 then figure 2 and image 3 The bobbin 20 is shown in more detail.

[0038] In the event of failure or failure of the external power source 10 (such as the public grid or a dedicated spinning mill grid), yarn production will be forced to stop. In order to be a...

Abstract

The invention relates to a method for operating a spinning machine, the spinning machine comprising a plurality of spinning units (3), fibrous composite (13) is transmitted to at least a portion of the spinning units (3) during a spinning process, in a present spinning station (4) of each spinning unit (3), rotation motion is transmitted to the fibrous composite (13), and therefore fibrous composite (13) turns into rotary yarn (7), the yarn (7) is taken off from the respective spinning station (4) through an outlet (6) and is wound up by a winding device (8), the spinning machine is supplied with power by an external power supply (10). The method is characterized in that the the yarn production in the spinning units (3) for producing the yarn (7) is stopped in case of failure or malfunction of the external power supply (10), so that a winding side yarn end is formed in the area of each spinning unit (3), each winding side yarn end is in the respective spinning station (4) or between the outlet (6) of this spinning station (4) and the winding device (8) associated with the spinning station (4), wherein the energy to for the further operation of the spinning machine until the end of yarn production is provided by at least one energy store (9). Furthermore, the invention also relates to a spinning machine which has a controller (11) which is designed to operate the spinning machine according to the above method.

Description

technical field [0001] The invention relates to a method of operating a spinning machine and to a spinning machine. Background technique [0002] A spinning machine usually comprises a plurality of spinning units arranged next to each other and / or one behind the other. The individual spinning units are supplied with fiber composite material during the spinning operation, for example via a corresponding spinning pot. The fiber composite material is withdrawn from each spinning pot by a conveyor and fed to the spinning station, where the fiber composite material is rotated so that the desired yarn is produced. The yarn is then wound onto bobbins by a winding device. [0003] In the event of failure or failure of an external power source (such as the public grid or a dedicated spinning mill grid), yarn production is forced to stop. In order to be able to carry out a targeted shutdown of each spinning unit and prevent damage to each machine component, in the prior art of the ...
