Definitions

  • the invention relates to a method for stuffer box crimping of a multifilament yarn according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 10.
  • a generic method and a generic device are from the EP 1 026 295 A2 known.
  • crimped synthetic yarns In the production of crimped synthetic yarns in a single-stage process, high demands are made, in particular, on the crimping produced in the yarn in terms of uniformity and stability, in order to enable immediate further processing into a flat structure, for example a carpet.
  • a multiplicity of filaments are first extruded from a polymer melt and combined to form a yarn.
  • To crimp the multifilament yarn is fed to a crimping device having a delivery nozzle and a stuffer box.
  • the delivery nozzle contains a thread channel, in which a delivery fluid flows in at high speed, so that the thread drawn in the thread channel is conveyed by means of the delivery fluid into the adjacent compression chamber.
  • the multifilament thread is laid down to form a thread stop, in which the filaments of the thread condense into loops and bows.
  • the thread plug is released by pulling off the thread, the filaments of the thread maintaining a fixed crimp.
  • the crimping in the yarn is dependent on a large number of directly interacting process parameters, such as, for example, the conveying speed of the yarn, the delivery pressure of the delivery fluid, the temperature of the delivery fluid, the speed of the yarn stopper, and the withdrawal speed of the crimped yarn Thread etc. depends. Due to the large number of interacting process parameters, simple monitoring and control of the crimping process can not be carried out.
  • Another object of the invention is to provide a method and apparatus for crimping a multifilament yarn in which Product changes can be implemented quickly and without major delays in process changes to stabilize the crimp.
  • the object is achieved by a method having the features according to claim 1 and by a device having the features according to claim 10.
  • the invention is characterized in that the interaction of several process parameters for generating the crimping is possible solely by monitoring a single parameter.
  • a structure-borne noise generated in a component of the crimping device is measured.
  • the structure-borne sound unites all dynamic processes taking place within the crimping device in order to form the multifilament yarn into a yarn plug. Irregularities in the crimp can thus be detected directly by changing structure-borne sound signals. In this case, all the signal characteristics typical for frequency analyzes can be used for monitoring.
  • the monitoring focus can be placed in the area of the thread guide or in the area of the thread rest. It is thus possible to measure structure-borne noise directly in the area of the thread channel or in the area of the stuffer box.
  • the method variant is particularly advantageous, in which a measurement signal of structure-borne noise is continuously compared with at least one stored reference signal and in which a control signal for changing at least one process parameter is generated with deviation.
  • the resulting control signal could be used to increase the delivery pressure of the delivery fluid.
  • this process variant can preferably be used for process adjustment at the beginning of a new process. In this case, optimized settings such as surface temperatures of godets can be found solely by constant comparison between the actual signal of structure-borne noise and the reference signal. By comparison with a stored reference signal, however, wear phenomena in the process units, such as the crimping device, can also be recognized and eliminated at an early stage.
  • the change in the measurement signal of structure-borne sound allows conclusions to be drawn directly about certain product properties and process settings. Therefore, the development of the invention is particularly preferably used, in which the measurement signal of structure-borne noise is continuously compared with a plurality of reference signals for identifying a process maladjustment or a product error and in which after identification of the process maladjustment or the product error, a warning signal and / or a control signal is generated.
  • the frequency spectrum of an insufficiently prepared thread showed a different characteristic than the frequency spectrum of structure-borne noise of a prepared thread.
  • the process misalignments can also indicate directly to signs of wear of the thread-guiding or thread-plug components, so that targeted exchanges of wear parts or cleaning cycles can be initiated.
  • errors on the crimping device can also be detected immediately, such as, for example, leaks in the delivery nozzle.
  • the measurement signal of structure-borne noise is also particularly well suited to give a quality assessment of the produced crimped thread.
  • quality levels of the thread can be defined.
  • the formation of a standard deviation of the measurement signal is advantageous, so that the process uniformity and product uniformity can be monitored in a simple manner in which the standard deviation is observed with respect to a predetermined limit value.
  • the determination of a quality signal which can either be output directly or can be assigned to a quantity of thread produced per period of time, which has been wound, for example, into a bobbin, is particularly advantageous in the process variant in which the limit value excesses or a limit value violation are observed over a longer period of time. This can also be advantageous to generate control signals to intervene in the process.
  • the device according to the invention has a structure-borne sound sensor, which is arranged on a housing component of the crimping device.
  • suitable mounting locations are both on the housing component of the delivery nozzle or the stuffer box.
  • a sensor directly in the wall of the thread channel of the delivery nozzle.
