Definitions

  • a regulating section has the task of stretching tapes of textile fibers about four to eight times and thereby making them as uniform as possible.
  • the most common type of these regulating lines in the short-staple spinning mill (e.g. in the cotton spinning mill) works on the principle of a closed control loop.
  • draft size the ratio of the peripheral speeds of two pairs of draft rollers
  • the cross-section of the strip is measured in a measuring element adjoining the warping zone and the measurement quantity obtained in this way is compared with a target value.
  • the resulting error signal influences the amount of delay in a known manner via an actuator.
  • control In the long-staple spinning mill, most regulating lines work according to the principle of the open control loop (so-called control).
  • control The belt cross-section entering the drafting system is measured with a measuring device and the warpage is controlled accordingly. It is important that both the running time T of the belt from the measuring element to the actuator and the overall gain V of the signal from the measuring element to change the actuator are taken into account.
  • Control drafting device is connected upstream. This works together with the control drafting system as an open control loop. It is therefore a combination of an open and a closed control loop within the same control drafting system.
  • the present invention takes these special features into account and relates to a method and a device for optimizing the stretching process in regulating sections of the textile industry in accordance with the features defined in the claims.
  • Fig..l shows a conventional arrangement of a closed control loop for a regulating path.
  • the textile material 10 passes through a draft zone 15 formed by a pair of rear drafting rollers 11, 12 and a pair of drafting rollers 13, 14 in front.
  • the pair of drafting rollers 13, 14 in front of the pair of drafting rollers 11, 12 is a factor of 4 to 8 driven higher peripheral speed; at least one pair of drafting rollers receives its rotary movement from a regulating gear with power electronics 16, which via a Control input 17 signals for maintaining certain speed ratios are supplied.
  • the textile material 10 leaving the warping area 15 passes through a first measuring element (measuring transducer) 19, the output signal U 19 of which is compared in a regulating electronics 20 with a setpoint value and is transformed such that a corresponding control signal reaches the control input 17.
  • the output signal U 19 corresponding to the cross section of the emerging textile material 10 thus influences the speed ratio of the pairs of drafting rollers in the sense of an equalization of the textile material 10.
  • FIG. 2 Another known arrangement is shown in FIG. 2, which forms a so-called open control loop.
  • a further measuring element (measuring transducer) 21 in the area of the textile material 10 running towards the draft zone 15, which measures its cross-section and converts the corresponding measurement signal U21 into a control signal in a further regulating electronics 22, which is transmitted via the control input 17 or a further control input 18 of the regulating gear 16 influences its output speeds.
  • a further measuring element measuring transducer
  • Fig. 7 shows the cross-sectional profile 71 with a sporadic thickening.
  • T transit time
  • a course 72 will result.
  • a cross-sectional profile of the emerging strip is indicated if the overall reinforcement is too great, but the running time is correct. The error determined as a sporadic thickening at the inlet to the drafting system has thus been overcompensated.
  • the so-called dead time between the delay field 15 and measuring element 19 means that short-term cross-sectional fluctuations cannot be compensated for.
  • An improvement, ie an at least partial compensation of even the short-term cross-sectional fluctuations can, as already mentioned in the introduction, by an additional second measuring element 21 can be achieved, which is connected upstream of the control drafting system 11-16 via further control electronics 22 (FIG. 3). It is therefore a combination of an open and a closed control loop with one and the same drafting system.
  • Measuring devices have recently become known which, even in the run-out of regulating sections, enable an almost inertia-free measurement, and thus also the measurement of brief cross-sectional fluctuations.
  • Such a measuring element is described, for example, in European laid-open specification 0 069 833 A1.
  • this measuring element now also allows an assessment of the setting of the control parameters of the open control loop.
  • the invention now consists in that, in principle, a further closed control loop is introduced which at least takes the signals from the measuring element 19, converts them into further electronics 23 and influences the parameters in the control electronics 22 of the open control loop (FIG. 4).
  • This further closed control loop according to the invention therefore does not act directly on the regulating path, but rather on the regulating parameters of the open control loop.
  • measurement signal U 19 is applied to the input of control electronics 22 located in the open control loop.
  • the correlation of the two measurement signals U 19 and U 21 enables the control parameters of the control electronics 22 to be determined. If, for example, a certain event is measured on the measuring element 21 (cross-sectional fluctuation), the measuring element 19 can be used to precisely check whether the total gain V and the running time T have been set optimally, or in which direction and by what amount further corrections are made should. A deliberate change in overall gain V and / or transit time T can thus be omitted.
  • Control electronics 22 and electronics 23 are combined in an overall electronics 24.
  • both the total gain V and the transit time T need not be constant quantities over the wavelength range of the cross-sectional fluctuations. They can be variable as a function of the wavelengths to be corrected.
  • the aforementioned correlations can be understood as simple methematic functions, such as addition or multiplication, or the known correlation function, such as cross correlation.
