Definitions

  • the invention relates to a method and a device for winding round material onto a spool provided with end flanges with the aid of an arrangement for rotating and axially displacing the spool and an axially displaceable pressing device which lies radially on the circumference of the spool.
  • the method and the device according to the invention are particularly suitable for strong, relatively difficult to bend round material such as strong round wires or cables, but can also be used in the same way for thinner materials.
  • a winding device which has a guide means for guiding the winding wire on the circumference of a rotating spool.
  • the guide means presses the windings of the wire together tightly.
  • a disadvantage of this device is that the deflection roller is slidably mounted on an axis and jamming and / or contamination can therefore result in jamming, so that permanent, secure guidance of the wire is not guaranteed. If the angle deviates by 90 °, increased friction occurs between the last winding and the new winding when winding onto the coil, which causes wear on the wire.
  • DE-OS 2 437 295 shows a winding device in which an attempt is made to control the tightness of the individual windings by means of a speed control device.
  • the control device includes sensors which are provided for detecting the position of the wire, by means of which the axial feed speed of the drum is controlled. Although the axial displacement of the drum ensures that the individual windings lie against one another to some extent, it is not possible with this device to ensure that the coil windings fit tightly against one another, since no guide means is provided for guiding the winding wire.
  • the invention has for its object to provide the means that ensure a reliable and accurate winding of round material, especially those with a larger diameter.
  • the winding device essentially consists of a winding motor 2 which is guided by an adjusting device 1 and which, if necessary with the interposition of a gear, serves to receive the winding spool 3.
  • a pressure roller 5 rests resiliently on the circumference of the roller.
  • the holder of the roller 5 is designed as an adjustment unit 4, by means of which the roller 5 can be moved parallel to the axis of the coil 3.
  • the roller 5 has the shape of a circular disc and lies with its circumference on the winding spool 3 or the lowest layer of the round material, with one of its side surfaces on the side of the wound round material.
  • the round material 8 to be wound is fed from a supply via a fixed roller 6. Between the roll 6 and the winding spool 3 there are two sensors 7 under the incoming round material, which emit a signal to a computing and control unit when the round material is located above one of the sensors due to lateral deflection.
  • FIGS. 2a and 2b The winding process is shown schematically in FIGS. 2a and 2b in the successive phases.
  • the lower part of the illustration shows a view perpendicular to the incoming round material, the upper part a view perpendicular to the direction of the incoming round material.
  • the axial displacement movements of the winding spool 3 and the pressure roller 5 are indicated by arrows.
  • the bobbin In the initial situation, the bobbin is in position (1), in which the round material 8 coming from the roll 6 is guided at a right angle to the bobbin axis without any clearance to the inside of the bobbin flange and can be fastened in a bore provided on the bobbin flange.
  • the pressure roller 5 is moved axially up to the distance of a material diameter on the spool flange and pressed radially there on the spool core. The rotary drive of the winding spool is then switched on and winding begins.
  • the pressure roller 5 is shifted following the coiled windings at the beginning of the winding, namely by one path per spool revolution, which corresponds to the diameter of the round material.
  • the winding spool is fixed in the axial direction. Alternatively, it can also be moved in the opposite direction to the pressure roller, but at a lower speed than the pressure roller. In this case, their displacement speed must be set so that the sum of the displacements of the winding spool and pressure roller per spool revolution is equal to the material diameter.
  • the incoming material for the following turns is only a distance that corresponds to the material diameter, so that the turns are wound side by side without any space between them.
  • the originally right angle between the bobbin axis and the round material coming from the roll 6 changes.
  • position (3) the angle has reached a value at which the sensor shown on the left is activated.
  • the signal emanating from the sensor has the effect that the displacement of the pressure roller is interrupted and the displacement drive of the winding spool is activated in a direction opposite to the displacement of the pressure roller (to the right in the lower illustrations).
  • the displacement speed is greater than a material width per spool revolution. If the winding spool is shifted more slowly in position (2), the speed in position (3) is increased accordingly.
  • the adjustment device 4 for the pressure roller is switched on again in position (7) and the winding of the second layer is started.
  • position (8) the deflection of the material has activated the other sensor, which causes the winding spool to shift or to increase the shifting speed to the left.
  • the winding is continued in this way with changing lateral directions.
