Definitions

  • the present invention relates to a method for cleaning a yarn from defects according to Preamble of claim 1 and a yarn cleaner Execution of the procedure.
  • the yarn is usually passed a measuring head, which is able to detect the defects. If an intolerable fault is found, then it is cut out. The yarn ends are back spliced and yarn cleaning continues. On corresponding procedure is e.g. in CH 680 803.
  • the thread must be removed to remove a defect stopped, which leads to a loss of time. Furthermore affects the splice when removing a fault occurs, the quality of the yarn. This leads to an accumulation of defects the cleaning process is extremely slow and many Splice points arise. In addition, the winding quality impaired.
  • a cluster when a cluster is detected suppresses cutting out of defects as long as until the cluster is over or until a predetermined maximum length of yarn has passed the measuring head. Thereby it ensures that a whole "cluster" of defects can be recorded.
  • the maximum length is included e.g. given by the length that is automatically removed can be.
  • the method according to the invention is preferred when winding yarn from one or more cops placed on a package.
  • a yarn cleaner according to the invention can e.g. be arranged at a rewinding station, as shown in Fig. 1 is shown.
  • the yarn 1 is made by one or several cops 2 rewound onto a package 3. there it passes through a yarn cleaner 4.
  • the yarn cleaner 4 comprises a measuring head 5, in which one or more parameters of the yarn are measured such as the yarn thickness or the presence of Impurities.
  • Appropriate devices are the specialist e.g. known from EP 553 446.
  • the signals from the measuring head 5 become one Control 6 fed where they are analyzed.
  • the controller 6 configured to discrete, to recognize individual imperfections in yarn 1.
  • a flaw is e.g. a thickening of the yarn in the form of a Nisse considered, in which the yarn diameter is one exceeds the predetermined limit, or a thin spot or a change in the optical reflection properties of the yarn.
  • the controller 6 can be between tolerable and intolerable imperfections, whereby e.g. is specified by the machine operator in which If the measured parameters are an intolerable defect describe. In the following, unless otherwise noted, under the term "fault" an intolerable Understood fault that removed from the yarn 1 must become.
  • the cheese 3 is stopped.
  • the yarn is rewound, the missing part removed and the yarn spliced again.
  • the purpose is a cutting and splicing device 7 intended.
  • the yarn cleaner has 4 two states. In a first state (normal mode) he works like a conventional yarn cleaner. In a second state (cluster mode) it works in a modified way.
  • the yarn cleaner 4 if it detects a "cluster end", i.e. when he no longer accumulates defects finds. This can in turn be the number of defects measured per unit length, or their distances. As soon as the number of defects per unit length one Falls below the limit (e.g. less than three defects on ten meters of yarn) or as soon as the distances between each other following defects larger than a given one Value (e.g. greater than three meters) takes the Control 6 indicates that the cluster has ended. The yarn cleaner 4 goes into normal mode.
  • Step 22 checked whether an (intolerable) Fault has been detected. Is that the case, it is checked in step 24 whether there is a cluster start, e.g. by using one of the above criteria becomes.
  • the yarn cleaner is after this Check in cluster mode (step 26), so there is a cluster of missing parts and an immediate cutting out the defect is temporarily suppressed.
  • the thread cleaner is at step 26 not in cluster mode, the defect is an isolated one Defect.
  • the controller 6 initiates immediately a cleaner cut (step 28).
  • the yarn 1 is cut in the area of the measuring head 5, the cheese 3 is stopped.
  • the yarn end is in the cutting and Retrieved splicer 7, there it will be the Cut missing piece of yarn and that Yarn is spliced. Then the rewinding operation of Again.
  • step 30 If there is no defect in step 22, then is checked in step 30 whether the yarn cleaner 4 in Cluster mode. If this is not the case, it is the yarn 1 is perfect and the execution goes to the point 20 back.
  • the yarn cleaner 4 is in step 30 in cluster mode, it is checked whether a cluster end is present (step 32).
  • One of the criteria mentioned above can be used.
  • the yarn cleaner 4 is after this Check no longer in cluster mode (step 34), so was one end of the cluster was detected. Now the cluster can removed from the yarn (step 36). To do this basically the same steps as in step 28 performed, the yarn 1, however, rewound as far is that the whole cluster will be cut out can. For this purpose, the controller 6 stores each the position of the cluster start.
  • the thread cleaner 4 is at step 34 still in cluster mode, so in one step 38 checked whether the length of the present cluster is one exceeds the specified maximum length.
  • This maximum length is given by the length by which the yarn 1 is maximal can be rewound (e.g. 80 meters). exceeds the length of a cluster this maximum length, so becomes the part of the cluster that already has the measuring head 5 happened, cut out (step 40).
  • a warning can be issued and if necessary the process can be stopped so that the machine operator if necessary, can replace the cops 2.
