Definitions

  • the invention relates to a method for winding thread-like material to be wound, in particular cables, onto a bobbin having a drum-like winding core and end flanges, in which the material to be wound is arranged in individual, adjacent turns, layer by layer applied to the winding core in such a way that the material to be wound in each turn over the largest part of the winding circumference with its center line, following an annular, endless curve surrounding the winding core, and then in a predetermined transition area, which makes up a small part of the winding circumference, by means of a winding material produced between the rotating bobbin and the wound winding material running towards it during winding a layer always the same directional step movement corresponding to the winding distance to the adjacent winding of the same layer and the winding material from the last winding of the first layer within the transition area
  • the object of the invention is therefore to provide a method which allows even difficult-to-wind winding material, for example cables, to be applied to a bobbin with a smooth winding core in such an order that the risk of irregularities in the bobbin structure is reduced to a minimum and This eliminates the need to have the rewinding process continuously monitored and corrected by your own person.
  • the winding method mentioned at the outset proceeds according to the invention in such a way that a rapid reciprocating, short-stroke movement in the longitudinal axis of the bobbin is additionally generated when the transition region between the rotating bobbin and the wound winding material which is wound up during winding is formed.
  • the winding material is thus given the short-stroke, fast, back-and-forth movement in addition to the stepwise movement which is always rectified within a layer and in accordance with the winding spacing. This ensures that the material to be wound is forced at defined points out of the respective turn into the transition area and out of this into the new turn and carries out the necessary changes in direction. In this way it is ensured that the transition areas, seen in the circumferential direction of the drum, turn out to be precisely defined, so that an exact winding structure is ensured even with multi-layer windings.
  • the procedure can be such that the individual turns of the first layer, starting with the first turn running outside the transition region with its center line approximately at a distance from the diameter of the winding material from the adjacent first end flange inner surface, extend over the length of the winding core in such a mutual manner Distance arranged net that the last turn outside the transition area is in the smallest possible distance to the second end flange inner surface.
  • the windings are therefore not closely wound lying on the winding core '. Rather, the distance between the center lines of adjacent turns is chosen so that the space between the turns is as small as possible, but it is sufficient that the last turn of the first layer that is formed has the smallest possible distance from the adjacent end flange inner surface to which the developing situation grows.
  • the location at which the material to be wound rises to the second layer is thus predetermined with sufficient accuracy.
  • the first layer forms a perfect support for the further layers to be built thereon, which is such that disruptions in the construction of these further layers are largely excluded.
  • the turns of the second layer are each laterally guided through the groove-shaped depression delimited between two adjacent turns of the first layer, so that the turns are properly fixed. This applies equally to all other layers of the coil.
  • the annularly closed curves, along which the winding material is applied to the winding core in each turn over the largest part of the winding circumference, advantageously lie in parallel planes which in turn run parallel to the inner surface of at least one of the end flanges.
  • they are circles, so that the individual turns outside the transition area are each circular rings.
  • the procedure can be such that outside the transition region, the ratio of the distances to the two inner end flange surfaces along the curve is constant for each of the annularly closed curves is.
  • At least one turn outside the transition area can run at a constant distance from its center line to the associated end flange inner surface, while for the turns in between, the ratio of the distances to the center lines at a constant distance from the center line the windings running inside the end flange is constant.
  • the turns of the first layer are applied to the winding core in such a way that they are not pressed close together.
  • the distance between the center lines of adjacent turns of the first layer is in each case equal to or greater than the largest outside diameter of the winding material to be expected or measured in the tolerance range.
  • the transition areas of the individual turns are located at precisely predetermined locations.
  • the arrangement can be made such that the transition areas in one position are delimited by two straight lines that are axially parallel to the longitudinal axis of the coil body.
  • the transition regions are delimited in one position by two helical lines.
  • the transition areas of adjacent layers can be angularly offset from one another.
  • a holding device which defines the turn distance from the adjacent end flange inner surface can be arranged on the coil former, which is designed, for example, in the form of a block.
  • This holding device can also be formed by a spindle, a wedge or an adjustable jaw. Blocks are also conceivable, which can be fastened from the outside or from the inside with the aid of a quick fastening. The adjustability or the quick change is intended to facilitate adaptation to different diameters of the winding material.
  • a centering device which is arranged in the opening and can be adjusted, if necessary, can serve the same purpose.
  • a tensioning device which can be displaced in the longitudinal direction of the bobbin can also be used for fastening the beginning of the winding material to the jacket of the winding core.
  • a support element which at least partially fills the space between the first turn and the adjacent end flange inner surface can be arranged on the coil former.
  • This support element can be designed to be axially and / or radially adjustable in order to allow adaptation to different diameters of the winding material. It is also conceivable that at least the first turn of the first layer and the last turn of the second layer are wound up with different tensile stresses of the winding material. By making the tensile stress smaller for the turns of the second layer in question, the first turn of the first layer is prevented from being pressed toward the adjacent end flange inner surface, which could lead to a disorder in the structure of the coil winding.
  • the first layer wound on the winding core supports the formation of the second layer, which is carried out according to the same rule. This continues through all layers of the Coil winding continues. Fluctuations in the outer dimension of the winding material in the direction of the longitudinal axis of the winding core can in no way influence the formation of the coil winding. In addition, the transition of the winding material from one layer to the next one is precisely predetermined, so that there is no need to separately detect and, if necessary, correct the rise of the winding material in the next subsequent layer during the winding process.
  • the winding method is illustrated by winding a cable onto a cable drum, which forms the coil former.
  • the method can of course be used to wind up any thread-like material to be wound, that is to say for ropes, wires, threads and the like.
  • the cable drum 1 shown in FIGS. 1 to 3 as a bobbin has a drum-like cylindrical winding core 2, on the end of which two circular end flanges 3, 4 are placed in a known manner.
  • the arrangement is such that the end flange inner surfaces lie in parallel planes which are perpendicular to the longitudinal or rotational axis of the drum, indicated at 5.
  • the deviations of the end flange inner surfaces from this right-angled arrangement are small in comparison to the diameter of the cable 6 to be wound, which in this case represents the material to be wound.
  • the cable drum 1 When winding the cable 6, the cable drum 1 is driven by drive means, not shown, known per se, so that it rotates about its longitudinal or rotational axis 5, the winding core 2, the cable 6 is fed via a guide device 7, which consists of two guide rollers 8, which are mounted in corresponding, also not illustrated bearing parts of the guide device. During the winding process, a relative movement is generated between the guide device 7 and the cable drum 1, which is controlled in such a way that the individual turns of the cable 6 are applied next to one another in a certain manner on the winding core 2 or on the respective underlying layer, as is shown in FIG each will be explained later.
  • the space between the end flange inner surface 4 and the transition of the cable from the penultimate turn 18 narrows at 190 in a wedge shape within the transition zone 13.
  • the location where this occurs is predetermined with sufficient accuracy by the position of the transition areas 13 for the control of the guide device 7.
  • the cable 6 is still guided on the level of its annular section, so that it does not yet change its position in the axial direction.
  • the transition into the annular section of the first turn 19 (FIG. 6) of the second layer 20, which is indicated in FIG. 5 by the dashed lines of the center lines 11 a of the turns of the second layer 20, then begins approximately in the middle of the transition region 13 are drawn.
  • the first turn 19 of the second layer is offset by half the turn distance from the last turn 17 of the first layer 9, which means that it is outside the transition region 13, i.e. over the largest part of its circumference, in which it again follows an annular curve 12 with its center line, into the channel-like depression 21, which is delimited by the circumferential surface of the last and penultimate turns 17 and 18 of the first layer 9.
  • the cable is transferred from the annular cut of the first turn 19 in the same way as for the first layer 9 in a transition region into the annular section of the second turn 22 of the second layer, whereupon the second Location is wobbled in a corresponding manner. Since the pitch of the turns is the same as in the first layer, all turns of the second layer 20 except the last turn 23 lie in the groove-shaped depressions 21 which are present on the surface of the first layer 9. The last turn 23 is supported on one side in the annular section outside the transition region 13 laterally by the end flange inner surface 3 and the first turn 14 of the first layer 9, as can be seen in particular from FIG. 6.
  • the cable 6 is then transferred from the last turn 23 of the second layer 20 into the first turn of the next layer, which is no longer illustrated.
  • the dashed line which indicates the center line 11 a of the last turn 23 of the second layer 20, changes into the full line 11, which from here not only the center line of the cable of the first layer 9, but also the third, fifth, seventh, etc. position. Accordingly, the dashed line 11 indicates the center line of the cable turns in the second, fourth, sixth, etc. position.
  • the transition regions 13 of the two layers 9, 20 lie one above the other on the circumference of the coil winding for the sake of simplicity; they are delimited by two straight, axially parallel lines 24, 25.
  • the transition regions 13 of the individual layers are not placed exactly one on top of the other, but are angularly offset from one another in order to avoid larger roundness of the coil winding.
  • the layer spacing is namely somewhat larger than in the region of the annular sections of the turns. Due to the angular mutual offset of the transition areas 13, an addition of these out-of-roundness errors is avoided.
  • the turns are applied to the winding core 2 such that outside the transition region 13 the ratio of the distances of the center line to the end flange inner surfaces 3, 4 is constant for each turn.
  • the arrangement is such that a certain number of the turns of the first layer closest to the two end flange inner surfaces 3, 4 — in the present case, the two winds Unions 27, 28 outside the transition area 13 with a constant, as small a distance as possible from their center line 11 to the associated end flange inner surface 3 or 4, ie following this, is applied while the windings in between are wound up in such a way that outside the transition area 13 the ratio of Distances of their center lines 11 to the center lines 11 of the turns running at a constant distance from the end flange inner surfaces 3, 4 are constant.
  • a centering device which is fitted in the passage opening and can be adjusted if necessary, can be used.
  • a tensioning device which can be displaced in the drum axis direction to fasten the beginning of the cable to the outer surface of the winding core 2, which is not shown in further detail.
  • the penultimate turn of the second layer 20 (FIG. 6) is applied, there may be a risk with high winding voltage that the first turn 14 of the lower layer 9 to the right, i.e. is pressed onto the end flange inner surface 3 and evades.
  • the blocks 30 or the ring segment part can in turn be axially adjustable.
  • the radial height of the blocks 30 or of the ring segment part above the winding core 2 can be made larger with increasing distance from the end flange inner surface 3, since with thinner cables 6 they remain substantially below the cable diameter must, while with thicker cables 6 it must not remain below half the cable diameter. This can be achieved by resting the blocks 30 on inclined planes or the ring segment part on a conical surface.
  • a uniform axial adjustment of the ring segment part can be forced by screw segments distributed over the circumference.
  • the ring segment part is rotated on the winding core 2 for adjustment in the circumferential direction.
  • the movements described are controlled by a control device which inputs at least the distance between the end flange inner surfaces and the largest expected or measured diameter dimension of the cable 6 in the direction of the cable drum.
  • the control device continuously receives information at least about the angle of rotation of the cable drum, starting with the angular position of the beginning of the first turn 14 of the first layer 9.
  • the control device calculates the smallest possible turn spacing that results from The two conditions result in that the center line 11 of the first turn is at a distance of the cable diameter from its adjacent end flange inner surface 3, while the last turn 17 of the first layer runs against the adjacent end flange inner surface 4.
  • the increase in the cable width in the drum axis direction in the transition area from one turn to the next is usually to be taken into account.
  • the diameter of the winding core 2 of the control device is entered as important information for this program in order to determine the position and the length of the transition area 13 of the individual turns for the first layer 9 in the form of a corresponding angular range.
  • the control device can calculate the layer diameter and, if necessary, correct it on the basis of measurement results, for example for the cable speed and the cable drum speed.
  • the information entered can also include information about the deviations of the end flanges 3, 4 from planes perpendicular to the longitudinal or rotational axis 5, which are then used in the movement program to achieve the winding profile in accordance with FIGS. 7, 8.
  • the winding up of the first layer presents no difficulties as long as the incoming cable 6 is not hindered by the end flange 3 to which the layer grows.
  • the cable 6, because of the end flange 3 cannot be at the angle required for the formation of the transition area 13 are fed.
  • the application of the last turns 17, 18 is nevertheless easily possible in practice, because in this case the previous turn already applied supports the formation of the transition area 13.
