Definitions

  • the invention relates to a device for regulating the tension in an axle winder with a speed control circuit for the electric winder drive and a computing circuit for determining a value proportional to the winding diameter from the web speed and the winder speed.
  • This generic term refers to an arrangement as described, for example, in the magazine Industrial Electronic Sept. 1968, pages 350 to 354.
  • the object of the present invention is. to create a simple indirect tension control, the speed control loop adaptively adapts to the changing winding diameters.
  • a desired tension in the web can be predetermined by the adjustable size proportional to the diameter. This applies to direct current and three-phase drives.
  • An electric DC machine 2 is used to drive the winding 3 and is fed from a network via a controllable rectifier 1.
  • the web 4 arriving from a processing machine (not shown) at a predetermined speed v s is to be wound up into a roll 3 on the axis winder, with a predetermined train in the web 4 during winding gear should be maintained.
  • the tax rate 6 of the controllable rectifier 1 is driven by a current controller 7 with PI behavior.
  • the actual value i of the current controller 7 is recorded on the AC voltage side and is a measure of the armature current - and, in the case of constant flux, also of the electrical moment - of the machine 2.
  • the setpoint i s of the current controller 7 is supplied by a superimposed speed control loop (main control loop) with speed controller 8 .
  • a variable V s which is proportional to the web speed of the web 4 and which is derived, for example, from a tachometer machine 5 moved by the web 4 serves as the target value v s of this speed controller 8.
  • a variable proportional to the product of the speed n and the diameter D of the winding 3 is used as the actual value v i .
  • a further superimposed correction control loop is provided with a correction controller 9 with PI behavior, which additionally gives a correcting variable to the input of the speed controller 8 in order to maintain the desired train.
  • This correction controller receives a variable proportional to the torque M i of the electrical machine 2, in the present case a variable proportional to the armature current i, and a desired value M S a variable adjustable to the diameter D kx D.
  • the factor k is a measure of the desired Train.
  • this correction control loop is relatively slow in relation to the speed control loop.
  • a control loop 14 which consists of the series connection a toggle amplifier 13, an integrator 12 and a multiplier 11.
  • the second input signal of the multiplier 11, which corresponds to the speed n of the winder 3, is supplied by a tachometer machine 16 coupled to the machine 2.
  • the signal nx D which arises at the output of this control loop 14 becomes the input of the control loop, ie the input of the Tilt amplifier 13 fed back and compared with the size proportional to the web speed v s .
  • the control circuit works so that it tries to continuously make the difference occurring at the input of the flip-flop 13 to zero.
  • a value must inevitably be set at the output of this circuit which corresponds to the product of the speed nx diameter D, since this value corresponds to the desired web speed or peripheral speed of the winder 3.
  • the size present at the other input of the waste multiplier 11 must be proportional to the winding diameter D.
  • This voltage which is established between integrator 12 and multiplier 11 is therefore used as the value for the winding diameter D.
  • a correction setpoint kx D proportional to the winding diameter can then be formed as the setpoint M S for the correction controller 9.
  • the value k is a measure of the desired train setpoint. If it is desired to change the train diameter depending on, can also in the line before or after the potentiometer 15th a function transmitter, not shown, can be installed, by means of which a change in the train depending on the diameter is effected.
  • control can be described in such a way that a correction control circuit is superimposed on a control of the peripheral speed of the winder, in which the actual value of the peripheral speed is calculated from the winder speed and the winder diameter. works as a torque control loop.
