Definitions

  • the invention relates to a device and a method for regulating the wire tension on a coil winding device according to the preamble of claims 1 and 13.
  • the tensioning forces for the winding wire in a winding system for electrical coils are to be kept constant in a predetermined value by an automatic wire tension regulator being arranged between a wire supply roll and the coil winding device.
  • the requirements for such a wire tension controller are diverse, since the wire tension can fluctuate greatly during the winding process due to the coil shape, the coil shape being round, square, rectangular, oval and the like. can be formed and is influenced by the growing diameter of the winding during winding. It must be taken into account that the wire speed, for example in the case of technologically related process sequences, can also assume negative values.
  • the fast effectiveness of the wire tension controller is particularly important because delays due to inertia bring uncontrollable wire-tension ratios, which can severely affect the quality of the finished winding.
  • the voltage is regulated, for example, by mechanical and / or electromechanical means, preferably by a wire compensation arm, optionally with a potentiometer assigned to it.
  • Devices of this type have major disadvantages caused by inertia, in particular due to a running or braking of the wire during a currently occurring negative wire speed and due to undesired vibrations of the wire compensation arm.
  • a device for regulating the tension of a wire for winding an electrical coil which provides for an improvement by automatically regulating the wire tension and braking it.
  • the device consists of a pre-brake, which is formed on two rollers covered with felt, one of which is permanently driven in the opposite direction to the direction of travel of the wire by a synchronous motor and the other is carried along as a pressure roller by the driven roller.
  • the pre-tensioned wire is guided through a grooved roller through at least 360 °, which is driven by a further motor in the wire run and wire return directions.
  • the grooved roller is connected to a tachometer, which emits a signal, whereby the motor is controlled by a controller.
  • a strain gauge provides a signal representative of the wire tension, which is compared to a set point. The resulting signal is superimposed on the signal from the tachometer in order to influence the controller via a control signal.
  • the change in wire tension affects the signal and the speed of the motor changes. to suppress this voltage change.
  • the quality of the wound coil at high wire speeds is impaired by voltage differences that occur.
  • the winding wire is guided over a spring-loaded swivel arm.
  • the winding wire then runs over a roller which is provided with a code disk in order to bring about appropriate corrections of the strain gauge signal via an additional control device.
  • a disadvantage which has an effect particularly in the case of multiple winding machines, is that the spring force of the swivel arm must be individually adapted for each winding point for each winding process influenced by the wire type and wire thickness.
  • Such a voltage regulation is less suitable for particularly thin winding wires which are wound at high take-off speeds and for which only the frictional force is decisive.
  • One advantage is the torque control of the brushless DC motor by means of a digital current control circuit, through which the speeds of the brake wheel are derived in an advantageous manner.
  • the setpoint wire tension control can also be changed without interruption during the winding process.
  • the digital parameter specification and digital control loops ensure precise reproducibility of the winding process.
  • Another advantage is that all the necessary control and regulating elements, including the power supply units, are integrated in the wire-pull regulator, so that additional control units are also unnecessary.
  • wire tension controllers By using a two-wire line (bus system), several, for example up to 32, wire tension controllers can be connected to a common machine control of the winding device, which can be individually programmed, and additional statistical and operating data can be recorded and registered.
  • a filamentary material such as aluminum, copper, tungsten, gold and platinum winding wires, but also plastic and glass fibers, preferably in the form of continuous fibers, is referred to below as a winding wire 25 , from a supply spool (not shown) in the direction of the arrow of a device designed as a wire voltage regulator 10-1 between a retraction roller 16 driven by a direct current motor 14 by means of a transmission 15 in the wire return direction and a pressure roller 17 which can be pressed on by means of a spring 19.
  • the pressure roller 17 carried by the retraction roller 16 can be pivoted out or delivered relative to it.
  • the retraction roller 16 and / or the pressure roller 17 is provided with correspondingly suitable coverings, for example made of felt, ceramic, metal, rubber, Vulkolan and / or of an antistatic material, with thin winding wires being made of antistatic material existing toppings are preferred.
  • the pressure of the pressure roller 17 can be adjusted by adjusting the spring length 19 depending on the type of wire and -thickness can be changed.
  • the revolutions of the retraction roller 17 vary according to the wire speed.
  • the winding wire is subsequently wrapped 360 ° in its groove by means of a brake wheel 22, the brake wheel being controlled by a brushless DC motor 20 with incremental encoder 21 in four-quadrants, in wire run or wire return. Direction is driven.
  • the brake wheel 22 is also provided with a flexible covering, preferably made of rubber, Vulkolan or the like, so that these measures ensure a non-slip wire guide in the wire run and wire return directions.
  • the applied voltage of the winding wire 25 is subsequently continuously determined by a pathless force measuring device, preferably a stretching strip 30, in that the winding wire 25 does not lead to a measuring roller 32 and the stretching strip 30 and at a constant angle around a wire deflection 34, for example an eyelet or swaging tail shown coil of a winding device is pulled.

  • An on / off switch 12 and a light indicator 13 "green / red (fault)" are also arranged on the front side of the wire-pull regulator housing 11.
  • the DC motor 20 is brushless and regulated in four quadrants, so that a long service life is guaranteed even at very high wire speeds of approximately 30 m / s.
  • an amplified rotor position signal S2 is supplied to a control unit 40 in the motor controller 28 and, on the other hand, an actual value torque signal S3 derived from an energy supply E supplied to the direct current motor 20 likewise influences the control unit 40 by means of a digital current control loop 20, S1.28, S3.40.
  • the setpoint wire voltage signal S6 or S6 ' is compared with a signal S5 amplified in an amplifier 38 with the instantaneous wire voltage 30, S4, 38, S5, 40 in the control unit 40, corrected if necessary (FIG. 3) as a manipulated variable.
  • Signal S7 to the motor controller 28 and in this amplified output as energy supply E to the DC motor 20 in order to convert the voltage of the wire 25 from its current actual value to the setpoint.
  • the digital wire tension control is superimposed on the torque control, with the DC motor 20 forming a closed control loop 30, S4, 38, S5, 40, S7, 28, E, 20 with the pathless force measuring device 30, preferably the strain gauge.
  • the strain gauge 30 prevents the tendency of the winding wire to oscillate, for example in the case of mechanical wire tension compensation elements.
  • the braking function of the DC motor 20 changes into a drive function, which can occur in particular in the case of a thin winding wire 25 running at a high wire speed.
  • the actual values of the wire speed K1 and the wire acceleration K2 are derived in the control unit 40, as will be described in more detail in FIG. 3, from the amplified rotor position signal S2 from the commutation system, which is the direct current motor 20, whereby the rotational speeds of the direct current motor 20 and an incremental encoder 21 is arranged on the DC motor axis for measuring the wire length.
