Definitions

  • the invention relates to a method for controlling the winding tension of a family of threads when forming a winding, in which the family of threads is fed to a driven winder via a driven pair of transport rollers and a dancer roller, in which the family of threads is further loaded, preferably pneumatically, on the dancer roller on the one hand and by a Circumferential speed difference between the pair of transport rollers and the winder is tensioned, on the other hand, and the winder speed is regulated relative to the transport roller speed with the aid of a programmable logic controller (PLC control).
  • PLC control programmable logic controller
  • the textile thread sheet to be wound is fed to the actual winder with the winding tree via a pair of transport rollers and a dancer roller.
  • the winding tension of the thread sheet is generated by loading the dancer roller, in particular by pneumatic action on the dancer roller.
  • the corresponding counter tension is obtained by setting a difference in the peripheral speed of the pair of transport rollers and the winding beam.
  • the dancer roller can basically perform movements following a changing tension of the thread coulter when the winder is operating, but in order to maintain a winding tension that is as constant as possible, it is necessary to specify a static resting point or working point of the dancer roller by the mechanical construction of the system and to keep it as precisely as possible during operation , the dancer roller is therefore only allowed to be very minimal Remove amounts on the order of 1 cm or less from the area of the specified static resting point. It is therefore not suitable for a basic control or rough correction of the winder speed in relation to the delivery speed of the thread group, that is to say the transport rollers which are in principle driven independently of the winder.
  • the invention has for its object to adjust the speed of the winding drive to the growing diameter of the winding so that the dancer roller is deflected as little as possible from the predetermined static point of rest.
  • the control system should be designed in such a way that manual regulation is not necessary; in particular, it should also be possible to start a winding process independently of the winding diameter without manual presetting.
  • the solution according to the invention for the above-mentioned method for controlling the winding tension consists in that the actual diameter of the winding is determined by ultrasonic distance measurement, converted into an analog output signal and fed to an analog input of a programmable logic controller as a controlled variable or rough correction value for the winding speed and that the signal of an analog dancer roll control with PID behavior is additionally supplied to the speed setpoint signal of the winding drive.
  • the actual diameter of the roll By scanning the actual diameter of the roll according to the invention with the aid of an ultrasonic range finder with an analog output signal and by forwarding This signal to a programmable logic controller enables a rough adjustment of the speed of the winding drive to the current winding diameter. If necessary, the actual diameter is determined from the ultrasound signal, checked for plausibility (e.g. a question is asked as to whether the winder is empty or there is a faulty measurement) and processed to an average. A pre-control value for the winder speed is calculated from the current diameter found in this way and the target value for the material speed.
  • plausibility e.g. a question is asked as to whether the winder is empty or there is a faulty measurement
  • the aforementioned rough adjustment of winder speed and winder diameter in relation to the delivery speed of the thread sheet is supplemented according to the invention by a fine adjustment.
  • the dancer roller which can be deflected from its static point of rest to a small extent during operation, serves this purpose.
  • the residual errors remaining for fine tuning as well as dynamic deviations and out-of-roundness of the growing reel, but also changes in the elasticity of the wound material, are eliminated by an analogous position control of the dancer roll with PID behavior by adding the signal of this control additively to the speed pre-control determined in the above-mentioned coarse adjustment.
  • Setpoint signal of the winding drive is supplied.
  • the textile thread sheet 1 to be wound is passed in the direction of the arrow 2 via a pair of transport rollers 3 and a dancer roller 4 to a winding 5 which is being formed in a winder which is denoted overall by 6.
  • the winding tension FW of the thread sheet 1 is generated by acting on the dancer roller 4 with the aid of a pneumatic cylinder 7.
  • the associated counter-voltage is obtained by setting a difference between the delivery speed of the pair of transport rollers 3 and the peripheral speed of the winding 5 that is being formed.
  • the pair of transport rollers has a drive 8, in particular a controlled direct current motor delivering an output speed n1.
  • the winder 6 has a drive 8 which is independent of the drive 8 of the pair of transport rollers, in particular also a controlled DC motor which supplies the output speed n2.
  • the actual diameter of the winding 5 growing in the winder 6 is scanned with the aid of an ultrasound range finder or ultrasound sensor 10.
  • This ultrasonic sensor 10 is intended to conduct an analog output signal on line 11 to a programmable logic controller (PLC), designated as a whole at 12, at its input 13. From the distance signal from the sensor 10, the actual diameter of the winding 5 is digitized in the PLC controller 12 in an analog / digital converter 14 and as the mean value of the actual diameter for the rough adjustment of a pilot control setpoint 16 Ratio of the speed of the transport roller pair 3 and the winder 6 used.
  • PLC programmable logic controller
  • a master setpoint is specified at an input 17 of the PLC controller 12 as the speed of the drive 8 of the pair of transport rollers 3.
  • the digitized master setpoint is fed via a line 20 to the control part 21 of the drive 8 via a digital / analog converter 18 and an output 19 of the PLC control 12.
  • the setpoint is fed from the input 17 via the n1 / n2 computer in the pilot control setpoint part 16 to an analog-digital converter 22 and via an output 23 of the PLC controller 12 and a line 24 to the control part 25 of the drive 9 of the winder 6.
  • the speed of the winder drive 9 is adapted to the growing diameter of the winder 5 in such a way that the dancer roller 4 is deflected as little as possible from its predetermined static rest point. Since the current winding diameter constantly enters the speed ratio n1 / n2 via the PLC control 12, the winding process can be started with any winding diameter without mechanical presetting.
  • the dancer roller 4 is usually mounted on the free end of an arm 26, while the arm 26 can be moved back and forth in the direction of the arrow 27 about a pivot bearing 28.
  • the deflection position by the angle w from the static rest point shown is detected by a potentiometer 29.
  • the potentiometer signal is fed to a PID controller 31 via a power 30.
  • the output signal of the PID controller 31 is superimposed on the analog signal of the pilot control setpoint 16 coming from the output 23 of the PLC control 12 in such a way that possible deflections of the dancer roller 4 are regulated to a minimum by an angle w in the direction of arrow 27 from the predetermined rest position.
