Definitions

  • This preamble refers to an arrangement as described, for example, in US Pat. No. 3,348,107.
  • the torque transmitted from the motor to the winding is regulated by means of an eddy current coupling in such a way that the desired train in the web and the required winding speed result.
  • the actual torque value for the control is determined from the current of the clutch and the setpoint in a potentiometer circuit with amplifier from the ratio of web speed to winding speed, i.e. calculated the winding diameter.
  • Such control of train and speed using a torque control loop is relatively sluggish and inaccurate.
  • the object of the present invention is to provide a simple indirect train control of the type mentioned, with the train and speed can be met precisely and sensitively.
  • 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, a predetermined train in the web 4 being to be maintained during the winding process.
  • 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 flow, 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.
  • As actual value v ; a size proportional to the product of the speed n and the diameter D of the winding 3 is used. These sizes correspond to the required or actual peripheral speed v . or v ; on the winding surface.
  • 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 the torque M as the actual value ;
  • the electrical machine 2 has a size proportional, in the present case a size proportional to the armature current i and, as a setpoint M s, a size kx D adjustable in proportion to the diameter D.
  • this correction control loop is relatively slow in relation to the speed control loop.
  • a control loop 14 which consists of the series connection of 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 n ⁇ D which arises at the output of this control loop 14 is fed back via line 17 to the input of the control loop, ie to the input of the tilting amplifier 13, and compared with the variable proportional to the web speed v s .
  • the control circuit works in such a way that it tries to continuously make the difference occurring at the input of the toggle amplifier 13 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 multiplier 11 Since the multiplier 11 forms the product n ⁇ D and the size n is located at one input, the size present at the other input of the 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. With a connected potentiometer 15, a correction setpoint k ⁇ D proportional to the winding diameter can then be formed as the setpoint M for the correction controller 9. The value k is a measure of the desired train setpoint. If it is desired to change the tension depending on the diameter, a function transmitter (not shown) can also be installed in the line in front of or behind the potentiometer 15, which causes a change in the tension depending on the diameter.
  • the regulation can be described in such a way that a correction control circuit is superimposed on a regulation 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.
