  • the disclosure relates to a device and a method for determining a classification of a current performance of at least one or more parts of a spinning mill.
  • Spinning mills include large numbers of textile machines and other components such as transport systems, power units, air conditioning devices, etc., and are designed for converting natural and man-made fibers and their blends into desired quantities of desired yarn types having desired properties, such as quality, structure, texture, etc.
  • a spinning mill or subsets of a spinning mill can be configured differently in order to produce different yarns. Some configurations of the spinning mill or subsets of the spinning mill can enable production of a single yarn type at high quantities, and other configurations of the spinning mill or subsets of the spinning mill can enable production of a plurality of different yarn types at the same time, e.g. at lower quantities each.

  • control devices and/or shift operators continuously monitor, control, maintain, etc. the spinning mill and/or subsets of the spinning mill, namely individual parts such as textile machines, transport systems, etc., as well as quality, quantity, etc. of intermediate or final textile materials. It is however difficult for control devices and/or shift operators to classify from this the current performance of the spinning mill, e.g. to classify if the spinning mill runs normally or abnormally.
  • control devices and/or shift operators should initiate actions, in particular for improving performance of the spinning mill or at least one part of it. Actions may include determining degraded parts of the spinning mill which may have an effect on the current performance of the spinning mill, maintenance work, configuration changes (e.g. adjusting conveyor or rotation speeds), relocation of production, etc.
