Definitions

  • the present invention relates to a device for depositing wire turns in a barrel.
  • wire should not only be understood to mean bare metal wire, but also wire that has already been processed, that is to say, for example, provided with a lacquer layer, insulation or the like, as well as coated or non-coated wire strands and the like.
  • Barrel winders of the type mentioned at the outset have a laying device with which wire, which is usually fed to the winder at high speed, is laid in turns around a non-rotatable cylindrical winding core arranged with a vertical axis.
  • the winding device is designed such that, as soon as a certain number of wire turns are placed on the winding core, the lowest wire turn falls into the barrel. Due to the high wire feed speeds, this process takes place relatively quickly, so that five turns or more fall into the barrel per second.
  • the barrel itself is also cylindrical, the (fictitious) cylinder axis coinciding with the (fictitious) cylinder axis of the winding core.
  • a barrel barrel, which is also cylindrical, is usually provided in the barrel and prevents the individual turns from getting tangled.
  • Drum winding devices have the advantage that large quantities of wire can be wound with them in a short time, which, if further processing is required, can in turn be drawn off from the drum very quickly.
  • a particular problem with barrel winders is changing the barrel. Due to the high speeds, the wire feed, for example from a rolling mill, a drawing system or the like, cannot be interrupted when the drum is changed. As described in DE-AS 20 38 133, it is therefore customary in the prior art to provide a number of sliding or pivotable magazine fingers arranged around the winding core, which fingers are moved towards the winding core as soon as the drum in the device is filled is. This prevents the wire windings from falling into the barrel and accumulates on the winding core. As soon as the new drum is positioned in the winding device, the magazine fingers are pulled back and the accumulated turns fall into the empty drum.
  • DE-AS 20 38 133 therefore proposes to design the magazine fingers in an arc shape in the manner of an iris diaphragm.
  • DE-OS 27 08 857 also shows a corresponding barrel winding device, in which four magazine fingers, referred to as sectors, are provided for catching the wire windings during the barrel change, which from an outer position in which they do not impair the falling of the turns into an inner position are convertible in which the turns are kept.
  • a wire cutting device is provided between the holding device and the barrel to cut the wire during the barrel change.
  • DE-PS 22 13 172 shows another barrel winding device.
  • a cylindrical extension piece is used, which is placed on the barrel core.
  • the wire is cut off during the barrel change.
  • the present invention for the first time creates the possibility of positioning the wire during the barrel change so that it is always essentially in the same position that does not prevent the accumulation of coils from falling.
  • a number of movable wire positioning fingers are provided which are guided on a rotatable ring which is arranged concentrically with the winding core, the positioning fingers being located below the magazine fingers.
  • the Movement of the positioning fingers with respect to the winding core is controlled so that the positioning fingers are moved in succession during a rotation of the ring holding them so that they come into abutment against the winding core one after the other.
  • a conventional barrel winding device is shown schematically, which has an outer jacket 1, and a concentrically arranged, fixed cylindrical winding core 2. Wire windings are placed on this winding core with a laying device, not shown in the figures. A device (not shown in the figures) is provided on the winding core, which means that after reaching a predetermined number of wire windings on the winding core, the lowest wire winding falls into a winding drum 4 arranged exactly vertically below the winding core.
  • the winding drum 4 which is usually composed of a metal rod, has an outer drum casing 4 and an inner drum core 5 arranged concentrically therewith.
  • the barrel winding device is arranged, for example, behind a wire drawing machine provided for non-ferrous metals and winds it out of the machine at a high rate Wire running out of speed.
  • the drum winding device is provided with an automatic drum changing device, by means of which the full drum moves to the left in the illustration according to FIG. 1A and an empty drum is positioned under the winding core 2. Since the production must not be interrupted during the barrel change, the wire windings that occur during this time are collected on the winding core 2.
  • four magazine fingers 11, 12, 13, 14 arranged at the same angular distance from one another are provided, which, as soon as the first barrel is filled, are moved towards the winding core by a device (not shown). If the full barrel 4 is now moved out of the barrel winding device to the left, the connection of the wire 6, which is now further wound onto the winding core, with the wire located on the barrel, which is indicated by the wire piece 6a, remains.
  • This wire connection is necessary in any case if the wire wound up in the individual drums is then to be further processed without interruption.
  • barrels 1 to 10 have been filled with wire, further processing can be carried out by subsequently pulling the wire out of the last, the tenth barrel and then in the appropriate order from the other barrels.
  • the wire connection 6a must also be present when the wire is cut between the individual barrels and the barrels are transported and processed individually. Since this processing is usually carried out again in automatic systems, it must be possible to empty it in the beginning to connect the wound wire end to the start of the wire of another barrel, for which the wire end must be accessible and must therefore be led out of the barrel before the winding process.
  • the wire loop lying at the bottom on the winding core can end both after the magazine finger 11 and after the magazine fingers 12, 13 and 14, so that the wire runs from one of these magazine fingers to the full barrel. If the situation arises, which is shown in FIG. 1A, that is to say the lowest wire winding ends at the magazine finger 11, the barrel change process is unproblematic. In this situation, the accumulated coils can fall into the empty barrel without interference.
  • a wire loop is formed by the course of the wire piece 6a around the magazine finger 11 to the magazine finger 13, which, after the magazine finger 11 is retracted, is so long that the wire turns easily fall down can and be picked up by the barrel without tilting and the like.
  • the position according to FIG. 1B is particularly critical, ie when the lowest wire winding ends at the magazine finger 12.
  • the wire can either run to the central axis of the winding core, as represented by the solid piece of wire 6a, or it can extend from the center point to the full barrel, as shown by the dashed wire piece 6b. In the latter case, a knot forms, which makes the further processing of the wire considerably more difficult.
  • the barrel winding device has a fixed, rotationally symmetrical winding core 2, the longitudinal axis of which is arranged vertically.
  • the winding core 2 has an upper, substantially tapering part 2a, which serves to support the wire windings, and an adjoining cylindrical part 2b, through which the wire windings are guided.
  • a cylindrical barrel 4 constructed from tubes, which has a cylindrical barrel core 5 which runs concentrically to the outer cylinder and which is tapered conically in its upper region 5a.
  • the (fictitious) cylinder axis of the barrel 4 coincides with the axis 3.
  • a jacket 1 of the barrel winding device is arranged concentrically with the winding core 2.
  • the winding core 2 has four openings 18 into which the magazine fingers engage.
  • the magazine fingers are simultaneously brought into a retracted position by a device (the position shown in FIG. 2), this device being known in the prior art and therefore not shown here.
  • a wire positioning device is arranged below the magazine fingers 11 to 14.
  • the wire positioning device has a circumferential ring 30 which is arranged concentrically with the winding core 2.
  • the ring 30 is designed as a pulley and receives on its outer circumference a V-belt 32 which is placed over a pulley 33 of a drive motor 35.
  • three wire positioning fingers 41, 43 and 44 are guided such that they can be moved towards and away from the cylinder axis of the winding core, as indicated by the double arrow 42 on the positioning finger 41.
  • Each of the positioning fingers 41, 43, 44 has a roller 46 with which it is guided on a link guide 47.
  • the link guide 47 has a first area 47a, which extends through approximately 180 ° of a circle in which the link guide runs concentrically to the winding core. In the clockwise direction there follows a second area 47b, in which the distance between the guide and the winding core is greatly reduced. This is followed, again clockwise, by an angular range of approx. 135 °, in which no guidance is provided.
  • turns of the wire entering the winding device are placed around the winding core 2 with a laying device, not shown, in order then to fall into the winding drum 4, where they are centered there by the drum core 5.
  • the magazine fingers 11, 12, 13, 14 are moved towards the winding core and prevent further turns from falling into the barrel. The turns are then accumulated in the area between the jacket 1 and the winding core 2.
  • the wire positioning device is actuated.
  • the motor 35 is switched on via a control device (not shown) and rotates, so that the rotatable ring 30 rotates in the clockwise direction.
  • the positioning fingers 41, 43 and 44 also move with the ring 30, being supported on the link guide 47 with the roller 46.
  • the link guide 47 has a partial area 47a which is arranged concentrically to the ring 30. As long as the rollers 46 rest against this part of the link guide, their distance from the winding core does not change.
  • the link guide In an angular position, which is seen in the clockwise direction behind the angular position of the magazine finger 11, the link guide is bent towards the winding core 2, so that the positioning fingers in this area are brought into contact with the winding core 2 via the rollers 46.
  • link guide is designed so that the positioning fingers only after the winding core Reach magazine finger 11, the wire, regardless of what position it is in, is always picked up by the first positioning finger 41.
  • the circumferential ring rotates from the initial position shown in FIG. 3 in the exemplary embodiment shown there by exactly 315 °. Thereafter, as can be seen in FIG. 4, this first positioning finger 41 lies exactly below the magazine finger 11, the second positioning finger 44 is located exactly below the magazine finger 14 and the third positioning finger 43 is located exactly below the magazine finger 13. Since the wire is always It hangs over the first positioning finger 41, thus ensuring that the wire is exactly in the position shown in FIG. 1A after this rotation by 315 °.
  • the full drum to the left in FIGS. 1 to 4 is removed from the winding device, for which purpose an automatic conveying device is usually provided.
  • a new drum is inserted into the winding device and positioned under the winding core 2.
  • the motor 35 receives a further control signal and now rotates in the opposite direction, so that the rotating ring rotates counterclockwise in the illustration according to FIGS. 3 and 4.
  • the positioning fingers reach the end of the link guide in area 47b, they are removed from the winding core by the link guide and finally return to their starting position.
  • the wire now hangs from the same magazine finger from which it hung before actuating the wire positioning device. However, it can no longer hang over the barrel core or form knots.
  • the magazine fingers are now opened and the accumulated wire windings can fall into the empty barrel without disability.
  • a total of four magazine fingers and three positioning fingers are used.
  • the number of magazine fingers and the positioning fingers can deviate from these numbers.
  • the link guide 47 is designed so that the feed movement of the positioning fingers to the winding core only takes place when this positioning finger has passed the magazine finger in the rotational movement, the position of which is optimal for the barrel changing process. It is also important that the rotary movement is continued until the first positioning finger, which comes into contact with the winding core 2, comes under this magazine finger 11 with the preferred position.
  • each magazine finger is used, each of which has a winding spacing of 90 ° to one another, and three positioning fingers, which likewise have an angular spacing of 90 ° to one another.
  • the starting position of the positioning device is such that the first positioning finger 41 is at an angular distance of 45 ° from the magazine finger 11 with the preferred position. Since the angular distance between this magazine finger 11 with the preferred position and the positioning finger 41 is 45 °, a rotation of 315 ° must be carried out in order to rotate this first positioning finger 41 under this magazine finger 11.
  • positioning finger only after the magazine finger with the preferred position reaches the winding core and is then rotated until it comes to rest under it.
