Definitions

  • the present invention lies in the field of textile quality control. It relates to a yarn clearer and to a method for clearing yarn, according to the preambles of the independent claims.
  • yarn clearers are applied for ensuring the yarn quality on spinning machines or winding machines.
  • a yarn clearer is known for example from EP-0'439'767 A2. It contains a yarn clearer measurement head with at least one sensor, which scans the moved yarn and measures at least one parameter of the yarn. It is the object of yarn clearing to detect yarn faults such as thick places, thin places or foreign matter in the yarn, to assess them according to certain quality criteria, and to eliminate them as the case may be.
  • the most common sensor principles are the following:
  • the measuring condenser measures essentially the yarn mass inside it.
  • the capacitive measurement principle has a high measurement accuracy and a sensitivity that is stable over many years. Its drawbacks are an undesired sensitivity to humidity changes and the non-usability with electrically conductive yarns.
  • the optical measurement principle cf. US-2006/164,646 Al .
  • the yarn is illuminated, and light reflected and/or transmitted by the yarn is detected.
  • the detected light is a measure for the yarn diameter and/or the optical characteristics of the yarn such as its reflectivity, color, etc.
  • the optical measurement principle is less sensitive to diameter changes and less stable over a long time than the capacitive. Nevertheless, it may be advantageous for those applications for which the capacitive measurement principle is unsuitable, e.g., in environments with strong air-humidity changes or for electrically conductive yarns.
  • Foreign matter in the yarn which has a reflectivity that strongly differs from that of the yarn base material, can be detected by the optical measurement principle in a simple way.
  • CN-2'896'282 Y mentions the combination of a capacitive and a photoelectric sensor for detecting the density and diameter, respectively, of the same yarn.
  • the two sensors are operated in a master-slave mode, and their signals are processed by applying a weighted synthesis of the two signals.
  • US-2003/107,729 Al teaches to arrange two sensors one after the other along the yarn path. A first of the sensors measures the optical reflection from the yam; a second of the sensors measures capacitively or optically the mass or the diameter, respectively, of the yam.
  • the output signals of the two sensors are evaluated according to certain evaluation criteria. Based on the evaluation, at least two kinds of foreign matters are distinguished from each other.
  • the basic idea of the present invention is to provide a yam clearer with a capacitive and an optical measuring cell, both measuring cells being adapted for detecting the yam

  • the yam clearer comprises a measurement head with a capacitive measuring cell and an optical measuring cell for detecting characteristics of a yarn.
  • the two measuring cells are arranged adjacent to each other in the longitudinal direction along a path of the yarn.
  • the yarn clearer further comprises an evaluation unit for comparing the detected yarn characteristics with predetermined quality criteria, and a cutter device for cutting the yarn upon a cut command from the evaluation unit.
  • the capacitive measuring cell is adapted for detecting yarn-mass variations and the optical measuring cell is adapted for detecting yarn-diameter variations.
  • the evaluation unit is adapted for outputting an unevenness cut command if the yarn-mass variation detected by the capacitive measuring cell and/or the yarn-diameter variation detected by the optical measuring cell do not comply with the predetermined quality criteria.
  • Both the capacitive measuring cell and the optical measuring cell are adapted for detecting foreign matter contents in the yarn.
  • the evaluation unit is adapted for outputting a foreign-matter cut command if the foreign-matter content detected by the capacitive measuring cell and/or the foreign matter content detected by the optical measuring cell do not comply with the predetermined quality criteria.
  • the yarn clearer comprises an input unit that allows an operator to input whether the yarn-mass variation detected by the capacitive measuring cell or the yarn-diameter variation detected by the optical measuring cell or both variations shall trigger the unevenness cut command.
  • the input unit may also allow an operator to input whether the foreign-matter content detected by the capacitive measuring cell or the foreign matter content detected by the optical measuring cell or both foreign-matter contents shall trigger the foreign-matter cut command.
  • the yarn clearer comprises a comparison unit for comparing the yarn-mass variation detected by the capacitive measuring cell with the yarn-diameter variation detected by the optical measuring cell and for automatically determining, based on the comparison, whether the yarn-mass variation detected by the capacitive measuring cell or the yam-diameter variation detected by the optical measuring cell or both variations shall trigger the unevenness cut command.
  • a comparison unit may also be present for comparing the foreign-matter content detected by the capacitive measuring cell with the foreign-matter content detected by the optical measuring cell and for automatically determining, based on the comparison, whether the foreign-matter content detected by the capacitive measuring cell or the foreign-matter content detected by the optical measuring cell or both foreign-matter contents shall trigger the foreign-matter cut command.
  • the measurement head may further comprise signal-processing units for pre-processing signals from the measuring cells, the evaluation unit and the cutter device.
  • the optical measuring cell comprises a light source, at least one light detector for detecting light transmitted by the yarn and at least one light detector for detecting light reflected by the yarn.
  • the light source is preferably a light-emitting diode, and one single light detector for detecting light transmitted by the yarn and two light detectors for detecting light reflected by the yarn are present.
  • the inventive method for clearing yarn characteristics of the yarn are detected by a measurement head with a capacitive measuring cell and an optical measuring cell, the two measuring cells being arranged adjacent to each other in the longitudinal direction along a path of the yarn.
  • the detected yarn characteristics are compared with predetermined quality criteria.
  • the yarn is cut if the detected yarn characteristics do not comply with the predetermined quality criteria.
