Definitions

  • the invention relates to a yarn cleaner according to the preamble of claim 1.
  • yarn cleaners which monitor, for example, the diameter of the yarn continuously with a non-contact measuring head. If an intolerable error is detected due to the exceeding of limit values designated as cleaning limits, the error is cut out of the yarn, the yarn ends are reconnected and the production process is continued as known, for example, from DE 10062479 A1.
  • a single reference diameter is determined and chosen for cleaning limits.
  • a reference diameter is the reference diameter for all further evaluations. Measured actual diameters of the yarn are usually given as a percentage of the reference diameter. It is an object of the invention to provide a cleaner whose application is increased.
  • the yarn cleaner according to the invention makes it possible to detect diameter-related yarn defects even with effect yarn.
  • the variability of the yarn parameter which is caused solely by the change between webs and effects, does not result in unnecessary cutting operations which would reduce productivity and create undesirable joints.
  • the yarn cleaner according to claim 4 can be set up.
  • the selection of only the effects may be due to the fact that the satisfactory bridge training is assumed, but the effect training is not reliable enough.
  • the amount of computation required and the number of times of cutting can be reduced.
  • the diameter of the effect yarn is primarily used as a yarn parameter, the cleaning limits being different depending on the respective measuring point, ie web or effect.
  • the web diameter also referred to as web thickness
  • the web diameter can be determined with a yarn cleaner according to claim 8 largely uninfluenced by the effects and thus close to reality. This also has a positive effect on the accuracy of the effect detection.
  • the boundary between web and effect can be determined with sufficient accuracy for the cleaning of the effect yarn.
  • FIG. 1 is a simplified schematic representation of a workstation of a spinning winder
  • Fig. 3 is a schematic representation of an effect area with adjacent web parts.
  • the effect yarn 1 is withdrawn through the take-off tube 2 from the spinning device 3 and wound onto the cheese 4.
  • the effect yarn 1 passes between the spinning device 3 and cheese 4 a yarn cleaner 5, which includes a measuring head 6 and a processor 8, and then a guide eye 9.
  • the yarn cleaner 5 is associated with a thread monitor 7.
  • the drive drum 10 drives the cheese 4 during the winding by means of frictional engagement.
  • a motor 11 gives the drive drum 10 the rotational movement.
  • the yarn cleaner 5 is used to monitor the quality of the current fancy yarn 1.
  • Der Garnrlick 5 is connected to other facilities for control, data storage or evaluation and the control of other elements of the spinning unit or the spinning machine by means of the line 12.
  • the components of the yarn cleaner 5 may be integrated in a common housing.
  • the effect yarn can also be withdrawn from a delivery bobbin instead of a spinning device.
  • Fig. 2 shows the representation of the effect yarn 1 as a juxtaposition of measured values. Although the regions of the effects 13 and of the webs 14 are recognizable, the beginning and end of the effects 13 and the effect thickness or the effect diameter D E and the web thickness or the web diameter D S / are not clear and therefore not sufficiently recognizable.
  • the yarn cleaner 5 registers the yarn diameter D at a distance of 2 mm.
  • One cycle represents a measuring length of 2 mm effect yarn 1.
  • the cleaner 5 first forms an arithmetic mean of the yarn diameter from a predetermined length of effect yarn 1 as a reference diameter at the start of the measurement, subtracts the reference diameter from the measured individual values of the yarn diameter and forms the mean value of the web diameter D s ⁇ as an arithmetic mean of all negative difference values that have been measured adjacent to other negative difference values.
  • the curve 15 increases and passes at point 17, the value of the limit diameter D GR .
  • the predetermined yarn length L v has passed since reaching the point 17.
  • the point 17 is defined as the beginning of the effect 13.
  • the curve 15 falls below the limit diameter D GR at the point 19.
  • the undershooting stops until the point 20 and thus over the predetermined yarn length L v .
  • the point 19 is defined as the end of the effect 13.
  • the area between point 17 and point 19 is defined as effect 13.
  • the section of the effect yarn 1 following point 19 or the end of the effect 13 is defined as a web 14 until a start of an effect 13 is determined again.
  • the effect diameter D E is assigned a predetermined tolerance range with a cleaning limit RG E0 as the upper limit value and with a cleaning limit RG EÜ as the lower limit value. Accordingly, the web diameter D s ⁇ is a predetermined tolerance range with a cleaning limit RG S ⁇ o as upper Limit value and with a cleaning limit RG ST u assigned as a lower limit.
  • the yarn cleaner 5 continuously determines whether the diameter values of the effect yarn 1 detected by the measuring head 6 originate from a region which is defined as a web 14 or as an effect 13. If the diameter values of the effect yarn 1 originate from a region which is defined as a web 14, these diameter values become with the limit values assigned to the web diameter D s ⁇ , the cleaning limit RG S ⁇ o and the
  • the yarn cleaner 5 may be arranged so that either only defects in land areas or only defects in effect areas are cleaned out.
  • the cleaning limits of the yarn cleaner 5 may be set so that they lie outside the fluctuation width B s of the effect 13 and the web 14 identified in FIG. 3.
  • the fluctuation width B s denotes the distance between the diameter of the effect 13 and the diameter of the web 14 and.
  • the continuously measured diameter values of the effect yarn 1 are compared with only the cleaning limit RG E0 and the cleaning limit RG S ⁇ u, for example, to detect overshoot.
  • the cleaning limit RG E0 denotes the upper tolerable limit of the effect diameter D E and the
  • the yarn cleaner 5 is set up so that the exceeding of these limits or cleaning limits registered as an untolerable error and this is cut out.
  • the yarn cleaner 5 is alternatively set up so that when these limit values or cleaning limits are exceeded, it is detected over which yarn length the exceeding continues.
  • a known two-dimensional classifying matrix also called a cleaner matrix
  • a classifying matrix is divided into length ranges in one dimension and into diameter ranges in the other dimension and forms a class by combining a length range with a diameter range.
  • the cleaning of yarn according to classes is known, for example, from the reference "Complete system for quality assurance in winding", Melliand - reprint October 1992, for a long time.

Abstract

L'invention concerne un nettoyeur de filé (5) destiné à la suppression par nettoyage des défauts d'un filé fantaisie (1) qui est constitué de la juxtaposition de segments alternants et d'effets constitués d'épaississements prédéterminés. Le nettoyeur de filé comprend une tête de mesure (6) dans laquelle au moins un paramètre de filé est mesuré. Le dépassement des limites de nettoyage, déterminées pour le paramètre de filé, indique la présence d'un défaut. Les valeurs mesurées du paramètre de filé sont comparées aux limites de nettoyage et les défauts intolérables sont enlevés du filé par coupe. Les limites de nettoyage sont différentes selon que l'on mesure les valeurs du segment ou les valeur de l'effet. Le nettoyeur de filé (5) permet de respecter la qualité de diamètre souhaitée du filé fantaisie des machines de filature/bobinage.
