Problems solved by technology

[0011] However, the disadvantage of this known textile machine is that, when processing the suction requirements of the individual stations, only the entry sequence of these suction requirements is taken into account
That is, there is no distinction between "normal" inspiratory demands and "emergency" inspiratory demands that should be prioritized

Embodiment Construction

[0029] figure 1 The front view schematically shows a textile machine for producing cross-winding bobbins, in this embodiment an open-end rotor spinning machine 5 . This textile machine has a plurality of identical stations 1 between its end frame 31,32, will combine below figure 2 These stations 1 are further described.

[0030] The vacuum source 30 of the machine's own suction system 20 is arranged in one of the end frames of the free-end rotor spinning machine 5 . The vacuum source 30 is driven here by an electric motor drive 29 whose rotational speed can be adjusted in a predetermined manner by means of a frequency converter. Such as figure 1 As shown in , for this purpose the drive 29 or the associated frequency converter is connected via a control line 33 to the central control unit 10 of the textile machine 5 . Such as figure 1 As further shown, the central control unit 10 is also connected to each control device 25 of a plurality of workstations 1 via a bus system...

Abstract

The invention relates to a method and an apparatus for operating a textile machine which produces crosswound bobbins, in particular for the distribution as required of vacuum which is provided by a vacuum system of the textile machine to workstations of the textile machine which require vacuum, wherein a central control unit of the textile machine ensures that the vacuum in the vacuum system does not undershoot a defined minimum level. There is provision according to the invention for vacuum requirements (UD) of the workstations (1) which arrive in the central control unit (10) of the textile machine (5) to be distinguished according to at least one first priority class (I) and one second priority class (II), wherein vacuum requirements (UD) which are categorized in the first priority class (I) are always processed with preference.

Description

technical field [0001] The present invention relates to a method for operating a textile machine for making cross-wound bobbins according to the preamble of the first aspect of the invention and a method for operating a textile machine for making cross-wound bobbins according to the preamble of the eighth aspect of the invention device. Background technique [0002] In connection with textile machines for producing cross-winding drums with a plurality of workstations, it is known that the workstations always require air suction during operation of the textile machine. Such textile machines are, for example, automatic cross-winders or open-end rotor spinning machines. [0003] Suction air is required, for example, at the stations of automatic crosswinders in order to continuously suck in the lint that is continuously generated during rewinding. Furthermore, the workstations of these textile machines are also used if, for example, after a yarn break or after a controlled she...
