Definitions

  • the invention relates to a method for operating a centrifuge spinning and twisting machine according to the preamble of claim 1 or a device for carrying out the method according to claim 16.
  • a drafting material is warped to the desired Garnfech by means of a drafting system and then transported via an axially displaceably mounted yarn guide tube in a rotating at high speed spinning centrifuge.
  • the original material is either a sliver stockpiled in a sliver or a roving, which is withdrawn, for example, from a flyer bobbin.
  • warped template material lays, forming a yarn leg, to the inner wall of the spinning centrifuge and is taken away by this. That is, the fiber material is rotated by the rotation of the spinning centrifuge.
  • the thread formed by the rotation distribution is deposited by the axially displaceably mounted thread guide tube on the centrifuge inner wall, where it forms a package, which is also referred to as a yarn cake.
  • the centrifuge speed and the delivery speed of the original material are the same coordinated so that the yarn deposited as a yarn cake already has its full rotation and can be wrapped in a subsequent step on a rewinding tube inserted into the centrifuge.
  • the resulting in this rewinding spinning cop is then dope and later rewound on a downstream in the production process winding machine to a large-volume cross-wound bobbin.
  • the centrifuge speed and the delivery speed of the master material are selected such that the yarn deposited on the inside wall of the spinning centrifuge in the first spinning stage initially receives only a portion, for example 60%, of its final rotation.
  • the lack of rotation is given to the yarn deposited as partially twisted yarn when it is withdrawn from the spinning centrifuge in a second spinning stage and is wound on an associated winding device directly to a large-volume cross-wound bobbin.
  • centrifuge spinning Due to the unknown scattering of parameters, centrifuge spinning therefore generally works with a high safety distance and thus exploits the maximum possible centrifuge filling in the very few cases.
  • U.S. Patent 5,621,637 a method is known which is used in the quality assurance of a textile yarn producing, for example, synthetic yarn.
  • the corresponding textile machines usually have a large number of similar, "regular" jobs and at least one reference job.
  • at least one process parameter is continuously sensed at each of the numerous "regular" workstations of the textile machine and the determined measured values are forwarded to a higher-level evaluation unit.
  • the corresponding process parameter is also monitored at the reference workstation and compared in the evaluation unit with a predefinable setpoint. From the process parameter measured at the reference workstation and the predetermined desired value, a manipulated variable is generated in the evaluation unit which is used to adjust the reference workstation to a desired work result.
  • the "regular" jobs can then be set properly.
  • process parameters which are monitored at the reference workstation and the "regular" workstations consideration is given to, for example, the thread tension before the winding operation, the wound coil spool contour, the so-called K value or the modulus of elasticity of the produced thread.
  • the present invention seeks to provide a method or a device by which the efficiency of a centrifugal spinning and twisting machine, regardless of the respective spinning or twisting process, can be significantly improved.
  • the inventive method has the particular advantage that in a simple manner at least one package parameters can be determined, so that due to its knowledge, the spinning volume of the individual spinning centrifuges of a Centrifugal spinning and twisting machine maximum utilized and so the efficiency of these textile machines can be significantly increased overall. In addition, by avoiding oversizing of the spinning centrifuges and the energy consumption of such textile machines can be minimized.
  • the growth of the yarn package formed in the spinning centrifuge of the reference spinning station is detected by means of a R (t) curve representing the size of the inner radius over time.
  • the spin time of the package is held in a coordinate system on the abscissa, while the values for the respective inner radii of the package are plotted on the ordinate.
  • the relevant Garn stressessparameter determined by means of the reference spinning station for each type of yarn stored in the central computer of the centrifugal spinning machine This means that in all later spinning processes, these stored values can be used directly and thus the spinning process at the "regular" spinning stations can be started immediately with the optimum settings.
  • a ⁇ KZ (R) curve characterizing the density of the structure of the package over the inner radius can be represented in a relatively simple manner.
  • a h kk (R) curve representing the respective conical contour of the package can be created.
  • the conical contour of the package may have, for example, a concave, a convex or a linear course.
  • the R (t) curve is also ideal for determining the minimum inner radius and the maximum cone angle of the package.
  • the jump in the R (t) curve is due to the occurrence of a string tendon or the sliding of thread layers from the cone of the package, which is reliably detected by the sensor device.
  • the incoming from the sensor device measurement data processed in the data acquisition and -ausute founded immediately to a statistical model. That is, for example, the estimated package parameters "minimum inner radius” and "maximum cone angle" of the package are calculated immediately.
  • the mean value for the density of the structure of the package can be determined relatively easily using the p (R) curve (claim 12).
  • the spinning station computers of the regular spinning stations are connected online with the data acquisition and evaluation device of the reference spinning station (s).
  • the "regular" spinning stations can shortly after the start of the Reference spinning station to be started.
  • the required Garn redesign can subsequently, that is as soon as they are present, transmitted to the winding stations of the "regular” spinning stations and these are set accordingly.
  • the online connection between the reference spinning station and the regular spinning stations also makes it possible to automatically readjust the regular spinning stations according to the data determined at the reference spinning station.
  • the device for carrying out the method according to the invention has, as set out in claim 16, a sensor device arranged in the region of the reference spinning station, which is connected to an associated data acquisition and evaluation device.
  • the data acquisition and evaluation device of the reference spinning station is in turn via a data transmission system, such as a data bus, connected at least to the central control unit of the centrifugal spinning machine.
  • the sensor device designed as an optical sensor device. That is, if the reference spinning station has a tube centrifuge, in an advantageous embodiment, as an optical sensor device, for example, a laser light barrier formed in the manner of a ribbon strip is used (claim 18).
  • the laser light barrier has a transmitter, for example, below and a receiver, which is then located above the tube centrifuge.
  • the laser light barrier records, layer by layer, the structure of the package formed on the inner wall of the spinning centrifuge of the reference spinning station and reports the determined measurement data to the associated data acquisition and evaluation device, where these are processed taking into account the traversing kinematics of the reference spinning station. This means that the relevant yarn package parameters are calculated directly in the data acquisition and evaluation device.
  • a CCD camera can also be used instead of a laser light barrier (claim 19). Even with such a CCD camera, a proper monitoring of the resulting package is guaranteed with appropriate image processing and short-term recordings. Such short-term recordings are relatively easy to implement, for example, by short shutter speeds of the camera shutter, in particular when using a stroboscopic flash.
  • the CCD camera is stationary, for example, installed at the reference spinning station and arranged so that at any time the resulting on the inner wall of the spinning centrifuge package can be monitored.
