Definitions

  • the present invention relates to an energy store for a winding device a thread, which a thread guide and a motor driven Driving wheel running and carrying the thread guide traversing element, wherein the Driving wheel is connected to the energy store.
  • a pinion is arranged on the drive shaft of the drive wheel, which engages with two gears, each at one end and at the other other end is firmly attached to the torsion bar.
  • Each torsion bar contains a device for adjusting its effective length, with which the length shortened a certain point before the reversal point of the thread guide and at Swinging back of the thread guide is returned to its normal value. Shortening the effective length of the torsion bars causes an increase in Torque characteristic.
  • the invention is now intended to provide an energy store for a winding device a thread which is compact and in the last area of the stroke causes no further increase in the torque characteristic.
  • the restoring torque is effective as evenly as possible stay.
  • a second preferred embodiment of the energy store according to the invention is characterized in that the connecting element with one end on the rotatable Element fastened and with its other end to the stationary element in the longitudinal direction is slidably mounted.
  • a third preferred embodiment of the energy store according to the invention is characterized by one provided between the driving wheel and the rotatable member Ratio, which is chosen so that the rotatable element at maximum stroke the thread guide performs a rotary movement of less than ⁇ 150 ° from the center of the stroke.
  • the said rotational movement of the rotatable element is not more than ⁇ 120 °.
  • the solution according to the invention is inexpensive, mechanically simple, compact and low-wear. In addition, it enables movement without discontinuities.
  • a fourth preferred embodiment of the energy store according to the invention is thereby characterized in that the connecting element by a bending beam with asymmetrical, preferably rectangular or elliptical, cross-section formed, and that the cross section is chosen so that the torque curve has a desired course having.
  • a fifth preferred embodiment of the energy store according to the invention is characterized in that the torque curve up to about 90 ° rotation of the Rotatable element a linear and then the smallest possible increase in Has reset torque.
  • the winding unit shown in Fig. 1 consists essentially of a motor-driven Spindle 1 for receiving and holding a coil sleeve 2, on which a coil, for example, a cheese 3, is wound up, and from a device 4 for Laying a thread.
  • the cheese 3 is exposed along a surface line on one rotatable roller 5, which is mounted on a suitable carrier part 6 of the winding machine is.
  • the thread laying 4, which serves to produce the desired winding, contains as the most important element, a thread guide 7, which along the axis of the bobbin 3 oscillating oscillating movement executes.
  • the thread guide 7 is attached to a traversing element 8, which is flexible and in the traversing direction, a rigid member for transmitting tensile forces is formed, and for example by a string, a wire, a metal rope, a flat, toothed or V-belt, a metal band, a chain or the like is formed.
  • the traversing element 8 runs over two deflection rollers 9 and 10 rigidly mounted on the carrier part 6 to one of a motor 11 driven drive wheel 12, which is composed of several turns of the traversing element 8 is wrapped and has oblique grooves to guide it (see Fig. 2). Both ends of the traversing element 8 are fastened to the drive wheel 12.
  • the motor 11 is generally a servo motor, such as a brushless DC motor or a stepper motor.
  • the thread guide 7 When driving the driving wheel 12, depending on the direction of rotation thereof, the thread guide 7 in the direction of one or the other deflecting roller 9 or 10.
  • the distance between the guide rollers 9 and 10 determines the maximum possible stroke of the thread guide 7 during its traversing movement.
  • the drive wheel 12 is in terms of the torque characteristic of the motor 11 and to the thread guide 7, thread and traversing element 8 formed load adjusted that an ideal efficiency results.
  • the motor 11 is a sensor (not shown) for detecting the rotational position of the Driving wheel 12 and thus assigned to the traversing position of the thread guide 7.
  • the sensor signal is fed to a control unit 13 which checks whether the motor 11 with the provided speed for the respective position of the thread guide 7 runs. In the event of deviations
  • the control unit 13 outputs a corresponding control signal between the actual value and the target value to the engine 11.
  • the control unit 13, which is part of a programmable Control forms, is connected to a machine control center via data lines which several winding devices of the type shown can be connected.
  • the paths, speeds and accelerations for are in the control unit 13 the motor movement due to the applicable winding laws calculated.
  • this information is determined in pulses with Intervals implemented and passed on to the power stage controlling the motor.
  • these time intervals are constant, with delays and accelerations lengthen or shorten accordingly.
  • the drive shaft of the drive wheel 12 is on the one Shaft of the motor 11 attached to a pinion 14 which drives a rotatable element 15.
  • the latter can be a gear, for example.
  • On the rotatable element 15 is one End of a bending beam 16 attached to the other end in a stationary Element 17 is guided.
  • the gear ratio from the pinion 14 to the rotatable member 15 is chosen so that the rotatable element 15 at maximum stroke of the thread guide 7 rotates ⁇ 120 ° from the center of the stroke.
  • the bending beam 16 has an asymmetrical, for example rectangular or elliptical, cross section, which is chosen so that the torque curve (Fig. 3) the desired course. You can also use more than one bending beam 16, to generate as little imbalance as possible. The torque characteristic remains in preserve their character.
  • the use of several bending beams has the advantage that the individual rods can be dimensioned smaller and lighter, which also regarding of the moment of inertia is advantageous.
  • Fig. 3 three torque curves M1, M2 and M3 are plotted as a function of the angle of rotation Phi, which show that the torque increases up to a certain angle of rotation and then decreases again after a flat curve.
  • the curves M1, M2 and M3 each correspond to a different restoring force R y acting on the bending beam 16 (FIG. 2) in the y direction.
  • the y-direction and the x-direction are the main axes of the bending beam.
  • the ratio R y to R x is selected so that the torque increases only slightly between 90 ° and 120 °. As can be seen from the figure, a ratio will be chosen which is just below the ratio corresponding to curve M2.
