Definitions

  • the invention relates to a device for reversing stranding of stranding elements, consisting of a fixed guide washer and a spacer arranged around it, rotatable about its axis stranding disk, both of which have axially extending through holes for the passage of the stranding elements, and a fixed point for fixation the stranded stranding elements at the stranding point (DE-AS 22 62 705).
  • Stranding elements in the sense of the invention are, for example, cores of electrical and optical cables or lines of all kinds. However, stranding elements can also be higher-order components in which several parts are already combined. These are, for example, pairs, quads or bundles. The stranding elements can also be threads made of plastic or bare metallic wires, which are used, for example, for the concentric protective conductor in power cables.
  • the reversing stranding in which the direction of lay of the stranding elements changes at intervals, has the advantage over the stranding method with the same lay direction that no rotating spools (baskets) are required which allow only a limited length for the stranded material to be produced.
  • the reversing stranding offers the possibility of continuous production with high take-off speeds.
  • the stranding elements are guided in tubes between the guide washer and the stranding washer.
  • These hoses are made of a plastic with a low coefficient of friction. They are intended to prevent the individual stranding elements from getting tangled between the two disks.
  • the hoses can easily become dirty, so that there are poorer coefficients of friction compared to the stranding elements. They also have a relatively large mass, which must be taken into account when dimensioning the device and in particular for driving the stranding disk. Furthermore, it cannot be ruled out that the hoses themselves may become entangled, especially if the distance between the guide disk and the stranding disk is large.
  • the invention has for its object to develop the device described above so that tangling of the stranding elements is avoided with a simple structure and simple setup of the same with certainty.
  • At least one thread-like, tensile support element is arranged between the guide disk and stranding disk, on which at least one holding element is attached at a distance from the guide disk on the one hand and to the stranding disk on the other hand, the through holes running in the axial direction for carrying out the stranding elements having.
  • This device is very simple. It consists of the guide disc and the stranding disc and a number of holding elements, which is determined by the length of the distance between the guide and stranding disc.
  • the holding elements can be made of a material with a low coefficient of friction, so that the stranding elements are exposed to a relatively low friction during manufacture.
  • the holding elements are low in mass, so that even with a larger number of them no significant additional masses are to be moved during the stranding of the stranding elements. Overall, they have a low rotational moment of inertia, so that the reversal times during stranding can be kept very short. With a sufficiently high number of holding elements, the stranding elements are guided properly during the stranding. Tangling is impossible.
  • the support element is designed as a torsion element which runs along a common axis of the guide disk and the stranding disk and is under tensile stress, which is attached to the stranding disk in a manner preventing rotation and to which at least one holding element is secured against rotation on the one hand at a distance from the guide disk and on the other hand to the stranding disk is.
  • the torsion element consists of at least two thread-like strands that are as closely adjacent as possible and a cover loosely surrounding the torsion element is placed around the same between two holding elements and between the guide disk or stranding disk and the closest holding element.
  • the guidance of the stranding elements is improved in that the holding elements are attached to the torsion element so that they cannot rotate. As a result, they participate in the rotation of the torsion element caused by the stranding disk. This is ensured in particular by dividing the torsion element into at least two strands which are as closely adjacent as possible, taking into account the structure of a stranded composite to be produced.
  • the between the individual holding elements and one each Covers attached to the retaining element and the guide or stranding disk protect the stranding elements during the stranding process against damage which could otherwise be caused by the torsion element without impeding the movement of the individual strands of the torsion element.
  • Fig. 1 gives only a schematic diagram again, in which the actual stranding path or the stranding memory is only indicated.
  • cores 1 three stranding elements 1 - hereinafter referred to as "cores 1" as representative of all other possibilities - are drawn off from coils 2 and fed to a guide disk 3. After passing through a stranding section 4, the more precise structure of which is shown in FIGS. 2, 7 and 8, the cores 1 reach a stranding disk 5. They are reversed stranded together in a stranding point 6 to form a core 7, which is drawn off in the direction of arrow 8 becomes.
  • the stranding disk 5 is rotatably supported, which is indicated by a bearing 9. It can be rotated around its axis in a reversing manner.
  • an electric motor 10 is used in known technology.
  • the stranding disk 5 makes eight revolutions in both directions of rotation. From the zero position, this is four revolutions in each direction of rotation.
  • the stranding point 6 is a fixed point in which the cores 1 are held so firmly that, due to the reversing stranding, the loosely bonded connection cannot open again.
  • a pair of rollers, an eyelet or a nipple can be used here.
  • a holder is applied to the core 7. This can be done by winding a tape or spraying on a coat.
  • the core 7 can be wound onto a spool or fed to further processing stations.
  • two holding elements 11, shown as disks, are attached in the stranding section 4, at a distance from one another and to the guide disk 3 and the stranding disk 5.
  • the retaining elements 11 are fastened to a thread-like, tensile support element 12, which is located between the guide disk 3 and Stranding disc 5 is arranged along the common axis.
  • Guide disk 3, stranding disk 5 and holding elements 11 each have three through holes 13 running in the axial direction, through which the wires 1 are pulled.
  • the support element 12 can consist of steel or plastic, for example of aramid. It is firmly attached in the guide disc 3 and stranding disc 5, but can rotate freely in both discs in one embodiment of the device. This can also apply to the holding elements 11.
  • the support element 12 is stretched between the guide disk 3 and the stranding disk 5.
  • a tensioning element can be used, which is attached to the side of the guide disk 3 or the stranding disk 5.
  • a spring, a weight or a pneumatic cylinder can be used as the clamping element.
  • the guide disk 3 and the stranding disk 5 preferably consist of metal, lighter material, in particular plastic, is preferred for the holding elements 11. They consist for example of polyamide or polytetrafluoroethylene. These materials have particularly good sliding properties.
  • the through holes 13 of the holding disks 11 can preferably be flared in order to make it easier to pull the wires 1 against the pull-off direction (arrow 8), as shown in FIG. 5.
  • Guide disk 3, stranding disk 5 and holding elements 11 can each also have a central through hole 14 according to FIG. 4.
  • a core or basic element of any structure can be drawn through the central through holes 14, around which the wires 1 are reversibly stranded. It is also possible to arrange a tube in the central through holes 14 through which the core or base element is drawn.
  • the central support element 12 is replaced by at least two support elements 15, as can be seen from FIGS. 4 and 8.
  • support elements 15 are distributed symmetrically in the circumferential direction of all disks and holding elements 11.
  • the holding elements 11 can also be attached to the support elements 15 in a loose and axially movable manner.
  • clamps 16 which are fixedly attached to the respective supporting element 12 or 15 on both sides of the holding elements 11. If two or more support elements 15 are present, it is sufficient if the clamps 16 are only attached to one of these support elements.
  • At least one holding element 11 is arranged between the guide disk 3 and the stranding disk 5.
  • the number of holding elements 11 depends on the properties of the wires 1 to be processed and on the distance between the guide disk 3 and the stranding disk 5. The greater this distance, the more retaining disks 11 are used. Their respective distance from one another can be constant but also arbitrary. In a preferred embodiment, the distance of the holding elements 11 from one another becomes smaller with increasing distance from the guide disk 3, as can be seen from FIGS. 7 and 8. In the area of the stranding disk 5 there are therefore more holding elements 11 for guiding the wires 1 than in the area of the guide disk 3. The wires 1 are thus guided more closely in the area with the larger angles of rotation.
  • the support element 12 is designed as a torsion element. It is therefore referred to below as "torsion element 12".
  • Guide disc 3, stranding disc 5 and holding elements 11 are secured against rotation on the torsion element 12.
  • the stranding disk 5 is driven by the motor 10 with an alternating direction of rotation. This is indicated in Fig. 2 by the arrow 17. Since the stranding disk 5 is connected to the torsion element 12 so that it cannot rotate, the same is twisted when the stranding disk 5 rotates. It thereby takes the holding elements 11, which are likewise connected to the same in a rotationally secure manner, and which accordingly are also rotated with an alternating direction of rotation. This is indicated in Fig. 2 by the arrows 18 and 19.
  • the torsion element 12 consists of three thread-like strands 20 which are as closely adjacent as possible.
  • the strands 20 lie so close together that a central torsion element 12 results with the smallest possible radial dimensions.
  • At least two strands 20 are to be used. However, there can also be more than three strands 20. Their number can depend on the number of wires 1 to be processed.
  • the wires 1 lay against the torsion element 12 during the stranding.
  • a protective cover is loosely wrapped around it.
  • this cover consists of hoses 21 made of plastic, which lie loosely over the torsion element 12 or over the strands 20.
  • the tubes 21 each extend from one holding element 11 to the next. They are also between the guide disk 3 or stranding disk 5 and the next holding element 11 in each case.
  • the hoses 21 do not obstruct the rotation of the strands 20 of the torsion element 12.
  • the tubes 21 are preferably made of the smoothest possible material with good sliding properties, such as polytetrafluoroethylene or polyamide.
  • the holding elements 11 are shown in FIG. 2 as disks. In a preferred embodiment, they consist of rings 22 according to FIG. 10, which are combined by the strands 20 to form a holding element 11. Each ring 22 is assigned a strand 20 so that the rings 22 through the strands 20th pressed against each other. The axial position of such a holding element 11 is fixed by the two adjacent hoses 21. This embodiment is particularly low in mass. When the strands 20 are twisted, the rings 22 and thus the wires 1 are carried along by them and thereby rotated in the circumferential direction. This also applies to the embodiment of the holding elements 11 according to FIG. 11, in which 22 disks 23 are used instead of the rings, in which the through holes 13 are made. Here, too, a strand 20 of the torsion element 12 is assigned to each disk 23.
  • a torsion element 12 consisting of strands 20 which are as closely adjacent as possible can also be used if a core 7 is to be produced with a core 24 which is carried out centrally.
  • a holding element 11 that can be used for this purpose is shown in FIG. 12.
  • the core 24 is not stranded in the device. It only serves as a base for the reversely stranded cores 1.
  • a prefabricated bundle of cores can be used as the core 24.
  • the core 24 is passed through a tube 25 around which the strands 20 of the torsion element 12 are arranged. They are as close together as possible.
  • the hoses 21 are arranged above the strands 20.
  • FIG. 12 shows six strands 20 which connect six rings 22 to form a holding element 11.
  • disks 23 are used again instead of the rings 22.
  • the number of rings 22 or disks 23 and thus the number of strands 20 is again arbitrary. It only has to be at least two at a time.
