Definitions

  • the invention relates to a winding device for producing an electrical coil by winding a coil wire on a bobbin and a method for operating the winding device.
  • Winding devices for producing electrical coils with a coil wire are known from the prior art. These have one or more bobbin receptacles on which to arrange the coil body to be wound and to store rotatably. Furthermore, these winding devices have wire guide tubes, through which a coil wire to the respective coil body to be wound can be guided. The wire guide tube is held in a receptacle and guided by this traversing parallel to a rotation axis of the bobbin, wherein a travel speed of the wire guide tube is controlled depending on a rotational speed of the bobbin and a thickness of the coil wire.
  • the winding method is performed by a winding machine having a nozzle which is movable while a wire is being discharged; a drive device that drives the nozzle; a direction setting device for the direction of the nozzle setting; and a winding portion rotating means having a winding portion rotating shaft for rotating a winding portion to wind the wire, and the wire being wound around a winding portion by rotation of the winding portion by the winding portion rotating means in a state where the direction of the nozzle is set so that the angle between the wire and the nozzle is set to 10 degrees or less.
  • the nozzle is through the Driving device at the times of start and finish of the winding moves, so that the wire is pulled to a wire attachment portion, which is positioned in the vicinity of the winding portion, and to which the wire is bound and fixed.
  • a coil for controlling a wire tension comprising a drive pulley on which the wire is wound and driven by a motor.
  • the pulley is provided with a tachometer which provides a signal and the motor is controlled by a power converter.
  • a strain gauge provides a signal that is representative of the tension of the wire and compared to a reference value. The resulting signal is superimposed with the tachometer signal to give a signal to control the power converter.
  • the voltage change of the wire affects the signal and the motor speed is corrected to eliminate this voltage change.
  • a wire tension regulator is arranged to regulate the wire tension on a winding device for electric coils, in which for Vorbremsung the winding wire, a retraction roller and a pressure roller to this is provided.
  • the winding wire is subsequently looped over a brake wheel through 360 °, wherein the brake wheel in Drahtlauf- and wire return direction by means of a DC motor can be driven and arranged between the brake wheel and the winding device, a stretch marks.
  • the DC motor outputs a signal of the rotor position to a motor control, which transfers it on the one hand as an amplified signal to a control unit and on the other hand, a derived actual value torque signal also passes to the control unit.
  • the controller also receives a setpoint wire voltage signal from the machine control or a setpoint wire voltage signal from the wire voltage selector, and comparing the setpoint wire voltage with a current wire voltage signal, the controller amplifying a setpoint signal to and from the motor control as an energy supply to the DC motor gives off to the voltage of the wire from its present value to the setpoint.
  • the invention is based on the object to provide an improved winding device and an improved method for their operation.
  • the object is achieved by a winding device with the features of claim 1 and by a method having the features of claim 10.

  • a tensile force acting on the reel wire can be determined by means of a wire tensioner which may be provided on the reeling device and through which the coil wire passes before reaching the wire guide tube.
  • the radial component of the force acting on the wire guide tube force during the extraction of the coil wire can be determined when the coil wire emerges from the longitudinal axis of the wire guide tube in an angle therefrom.
  • the tensile force of the coil wire at an inlet of the wire guide tube is also determined by the wire tension regulator in this case. However, it also results in a frictional force of the coil wire at the outlet of the wire guide tube, which adds to the determined by the wire tension regulator traction. If an exit angle of the coil wire from the wire guide tube with respect to its longitudinal axis known, it can be determined by a trigonometric calculation of this angle and the measured radial component of the force acting on the wire guide tube force acting on the coil wire after the outlet of the wire guide tube tensile force.
  • the bobbin typically has a winding area, comprising at least one surface lying parallel to the axis of rotation, and two flanges delimiting the winding area at its ends. At least one of the flanges points at least one, for example, radially arranged to the axis of rotation slot, through which the coil wire before the winding process, for example, from a bobbin post, from the outside into the winding area and after the end of the winding process can be performed out of the winding area, so that the coil wire largely enters the winding area axially.
  • the guiding of the coil wire into and out of the winding area through the slot (s) can also be done by appropriate method of the wire guide tube.
  • the coil wire can be determined on the basis of the determined by the force measuring device force curve, whether the coil wire was passed correctly through the slot. For example, in the event of improper guiding, the coil wire can be guided over the edge of the flange instead of through the slot, resulting in a significantly higher pulling force. If the coil wire subsequently slides into the slot, a corresponding drop in tensile force results.

If the knife is firmly connected to the receiving device of the wire guide tube, the force measuring device arranged on the receiving device can also carry out this measurement. Before winding another coil, the coil wire fixed at its end to the parking pin is guided by means of the wire guide tube to another bobbin post on the bobbin, terminated there and then separated the coil wire between the parking pen and bobbin posts by cutting or tearing. By monitoring these processes by means of at least one of the force measuring devices is understandable whether the coil wire was actually cut or torn, for example, based on a sudden drop in the measured force.
