Definitions

  • the invention relates to a stranding element, with at least one essentially stationary storage container for the goods to be stranded and with at least one rotating guide device for the goods for guiding the goods from the storage container substantially parallel to the axis of rotation of the guide device in the direction of the stranding area, the guide device in one Support structure is rotatably mounted, according to the preamble of claim 1, as well as a stranding machine with a plurality of storage containers for the material to be stranded which are essentially stationary during operation and with at least one rotating guide device for the material to guide it from each of the storage containers to a common stranding area , according to the preamble of claim 11.
  • a stranding machine is an apparatus with which, for example, electrical lines, steel, copper and aluminum wires as well as insulated wires, which consist of several single wires, are twisted into cables.
  • the shape of the cable is determined by the number of single wires, the arrangement of the single wires and the lay length.
  • the simplest machines consist of a bobbin around which a rotor with the individual wires moves. The lay length is determined depending on the rotor and spool speed. Many coil carriers are arranged on the rotor, which only allow the production of thin cables. For thicker cables and in particular thick and heavy goods to be stranded, other constructions of stranding machines have to be used, such as in particular tube stranding machines.
  • Tube stranding machines such as those used in the US 2371523 A are made up of welded storage racks in which a stranding tube is mounted in a central bearing.
  • bobbin supports for the material to be stranded are essentially stationary, but typically oscillate.
  • the goods are transferred from the coil carriers to the outside of the stranding tube and from there along the tube to the stranding area.
  • these stranding machines take up a lot of space, are very complex and cannot be easily expanded as required if cables are to be made from more wires than there are coil carriers. If, on the other hand, cables are to be produced from fewer individual wires than the tube stranding machine has coil carriers, the entire tube must nevertheless be moved, which leads to unnecessary expenditure and energy consumption and thus also increased production costs for the cable.
  • the object of the present invention is therefore to provide a stranding element with which even thick and heavy material can be stranded, and which can be flexibly and easily adapted to the particular stranding task, in particular with regard to the number of individual wires to be stranded.
  • the at least one guide device is rotatably mounted by means of a bearing arrangement, which bearing arrangement lies entirely within the flight circle of the goods and via at least one holding arrangement which extends radially beyond the flight circle of the goods and is axially spaced from the guide device is fastened to the support structure, which holding arrangement has at least one passage which opens at least temporarily for the passage of the goods in the circumferential direction and follows the flight circle of the goods.
  • the storage of the rotating parts can be accomplished in structurally simple, compact and functionally reliable central bearing arrangements for the bearing axes which coincide structurally with the axis of rotation of the rotating parts.
  • the guide device preferably comprises a stranding disk rotatably mounted in the bearing arrangement with at least one guide for the material to be stranded.
  • Such disks have a lower rotational moment of inertia, so that the guiding device for the material to be stranded can be accelerated more quickly and, in an emergency and when production has ended, can also be braked more quickly and with less effort.
  • each guidance typically a bore passing through the stranding disk, preferably runs on the holding arrangement opposite side of the stranding disk from a guide tube, which guide tube is supported in an auxiliary stranding disk of the stranding element or in another stranding element following in the direction of the axis of rotation.
  • At least one guide tube is designed in the wall of a cylinder tube, the axis of rotation of the cylinder tube being rotatably mounted on at least one end face in a bearing arrangement.
  • an advantageous embodiment of the invention is characterized in that the holding arrangement has a central area, preferably a disc, preferably parallel to a possible stranding disc and with an essentially circular peripheral edge with a smaller radius than the flight circle of the material, the central disc in a radial Carrier structure lying outside the flight circle is held in a stationary and rotationally fixed manner by means of at least two holding devices, with at least one of the holding devices always holding the central disk and each holding device, in the immediate vicinity of which there is currently a guide for the good, opening a passage gap for the good to be stranded , This ensures a stable fixation of the compact, central bearing arrangement.
  • a particularly good position fixation results in an arrangement with at least three holding devices, at least two of which always hold the central disk.
  • a preferred variant of this holding arrangement provides that the central region of the holding arrangement is fixed in place and in a rotationally fixed manner in a holding ring lying radially outside of the flight circle via a plurality of holding elements which are preferably distributed uniformly along the circumference of the holding ring, with at least two holding elements always being the central one Connect the disc to the retaining ring and move each retaining element, in the immediate vicinity of which there is currently a guide for the good, out of the area of the flight circle of the good and open a passage gap for the good to be stranded.
  • the holding element is designed as a pin which is essentially radial and longitudinally movable and is mounted in the central disk or the holding ring and which engages in the holding position in corresponding bores in the radially opposite component, the holding element preferably pointing towards the holding position is biased.
  • the stranding disk is preferably provided, at least in the area of the guide, with a cam-like structure or a positive guide, which brings the holding element, which is in front of the guide in the direction of rotation, out of its holding position from the area of the flight circle as soon as the guide passes the holding element, and preferably over the remaining peripheral area holds the holding element in the holding position.
  • the positive guidance interacts with the holding element lying ahead of the guidance in the direction of rotation via a sliding element guided or continuously abutting in this positive guidance or a roller running thereon, in order to actuate this element connected to the holding element or this roller radially depending on the angular position of the stranding disk and thus to bring the holding element from its holding position into a position spaced from the holding and guide ring, only when the guide passes the holding element, and to hold the holding element in the holding position over the remaining circumferential region in order to achieve the desired secure holding function of the holding elements and their release Passage for the goods to be stranded as they circulate around the stranding disk.
  • the holding arrangement comprises a central region, preferably a central star-shaped or triangular-shaped disk or a spoke-like structure, which central region by means of a plurality of radially outward and projecting essentially radially outward from the central bearing arrangement beyond the flight circle Holding devices in the support structure is held in a stationary and rotationally fixed manner, these holding devices being arranged in the region of the trajectory of the good preferably equally distributed in the circumferential direction of the holding arrangement, and wherein the holding devices support the central disk in the support structure at all times, but in doing so a passage of the Allow good in the circumferential direction.
  • This construction ensures the optimal holding effect on the central area with the bearing arrangement for the stranding disk, which ensures that it runs smoothly even at high speeds.
  • each connection arrangement comprises at least one roller rotatably attached to the central region or to the support structure, preferably a plurality of rollers spaced apart in the circumferential direction of the holding arrangement.
  • the axes of all the rollers are oriented parallel to one another and preferably parallel to the axis of rotation of the stranding element, and the contact points of the outermost rollers, each with an opposite roller, lie on circumferentially opposite sides of a radial connecting line between the axis of rotation and the opposite roller.
  • At least one recess is advantageously on the outer circumference of one of the rollers projecting into the flight circle of the goods provided that have a dimension such that the material can be received in this recess and can be transported past these roles without hindrance and preferably without contact with the contacting opposite roles in the course of the rotation of the role. Two or more such recesses are preferably provided.
  • the material coming into the area of the rollers of the holding arrangement on the outer circumference of the stranding element enters the recess in the roller, which recess has the same peripheral speed as the stranding element and thus also the material to be stranded when the roller rotates.
  • the goods and the recess therefore continue to move in the area of the intersection of the circles on which they move, with the same circumferential speed without mutual interference, until the goods have passed the holding arrangement and can then emerge from the rotating recess.
  • the extension extends Recess in the circumferential direction of the roller preferably parallel to the axes of rotation of the rollers over an area which is at most the smallest distance between the contact points corresponds to two adjacent, opposite rollers with this roller with the recess, so that the roller with the recess is in contact with at least one of two opposing adjacent rollers at any time.
  • An alternative embodiment provides that the recess in the roll is inclined but equidistant from the axis of rotation, the boundaries of the recesses in the circumferential direction of the roll being spaced apart by at least the circumferential width of the recess, and the roll being in contact with everyone at all times opposite role is.
  • This type of construction enables continuous mutual contact of only two rollers, since, seen across the width of the roller with the recess, an area always touches and is supported on the opposite roller. This ensures a smooth, shock-free run while still allowing the goods circulating on the flight circle to pass through, albeit with a certain deviation from the direction of transport of the goods in the area in front of and behind the respective holding arrangement.
  • At least the rollers with the recess can be driven at an angular velocity proportional to the angular velocity of the guide element, wherein there is preferably a functional drive connection, for example using toothed belts or the like, between the drive of the stranding disk and the rollers.
  • the recesses can thus always be held in the optimal position relative to the material to be stranded, in order for the material to enter and exit the recess as gently as possible and to pass each roller arrangement as gently as possible, preferably without direct contact with any of the Roles to ensure.
  • At least one of the holding arrangements is designed for electrical contacting of the carrier element and possibly other components or assemblies of the stranding element, and either at least one role of the support element with current consumers and / or sensors and / or actuators on the stranding element or at least one role of the support structure or at least one of the holding elements for the electrical connection of the holding ring to the central area, and that the holding and guide ring with power consumers and / or sensors and / or actuators on the stranding element or the at least one holding element is connected to power and / or data lines from and / or to external power sources, evaluation, control or display units or the like.
  • the stranding element can have a holding arrangement, the central region being held in a stationary and rotationally fixed manner in a carrier structure lying radially outside the flight circle by means of at least one holding device, each holding device comprising at least one bearing with an air gap, preferably a magnetic levitation bearing, the Air gap extends along the flight circle of the good.
  • This information also includes arrangements with a straight air gap that is tangent to the circular flight circle.
  • the contact-free, preferably magnetic mounting ensures the unhindered passage of the goods to be stranded through the holding devices, the cross section of the passage for the goods on the flight circle being able to be adjusted or actively adapted, depending on the strength of the magnets or the amount of air active magnets can be used.
  • Air bearings are basically plain bearings, in which the compressed air pressed into the bearing gap between the sliding surfaces moving towards each other forms the lubricant. This also creates a pressure cushion that carries the load of the mounted component without contact.
  • aerodynamic bearings which build up the air cushion through the movement itself
  • aerostatic bearings in which compressed air is introduced to build up the pressure cushion.
  • the compressed air is typically provided by a compressor, with the highest possible level being desired for the pressure, the rigidity and the damping of the air cushion.
  • Aerodynamic bearings do not require compressed air supply, but have the problem that the two bearing partners touch below a characteristic relative speed (linear or rotary) and therefore have friction that leads to wear.
  • At least one of the magnetic levitation bearings preferably extends along a circumferential section of the stranding disk and its air gap follows the flight circle of the goods over a corresponding circumferential section.
  • At least one of the magnetic levitation bearings is designed as an active magnetic bearing, since in this case the holding force and also the load-bearing capacity of the bearing of the bearing arrangement and thus also the air gap for the passage of the goods to be stranded are set and - within certain limits to the can be adapted to individual needs.
  • At least one of the active magnetic levitation bearings can advantageously be combined with at least one permanent magnet which is matched to the weight of the stranding element.
  • the holding arrangement preferably has at least one magnetic axial bearing, so that the stranding disk also needs as few moving components as possible for positioning and storage in the axial direction.
  • the problem stated at the outset is achieved in that at least one of the storage containers and an associated guide device are elements of a stranding element according to one of the preceding paragraphs.
  • Such a stranding element can preferably be operated and handled independently of other stranding elements and thus forms a separate functional and structural unit.
  • the combination of the functional units into structural units ensures that an existing stranding machine can in principle be expanded as required with a certain number of these units if cables are to be stranded from more individual wires than is possible with the original machine.
  • individual units of existing machines can be easily and quickly removed and reinstalled for maintenance, repair or replacement, since the individual units can also be handled individually and separately from all other units.
  • two or more of the stranding elements described in the previous paragraphs are connected to one another in a rotationally fixed manner.
  • the connected stranding elements can preferably also have a common drive.
  • a further preferred embodiment of the invention provides a stranding machine in which the guide device closest to the stranding area for a plurality of storage containers is formed from a stranding tube rotatably mounted about its longitudinal axis, inside of which the storage container for the material to be stranded is preferably opposite the stranding tube are mounted in an oscillating manner, and in which at least one further stranding element which can be operated and handled separately and independently of the stranding tube is provided in accordance with one of the preceding paragraphs.
  • This embodiment enables the modular expansion of existing tube stranding machines by any number of stranding elements in principle, in order to be able to strand the exact number of strands depending on the production requirements. If, on the other hand, fewer strands are to be processed than would be predetermined overall by the stranding tube and stranding elements, the stranding elements which are not required can simply be switched off, uncoupled and possibly even removed.
  • Fig. 1 shows a conventional tube stranding machine, as used for example for the production of twisted cables from several individual wires.
  • the individual cores can be electrical lines, steel, copper or aluminum wires and insulated cores, the shape of the cable being determined by the number of individual cores, the arrangement of the individual cores and the lay length.
  • storage containers 2 for the material to be stranded preferably on bobbins mounted on pendulum-suspended bobbins, are stored.
  • the material to be stranded is guided away from the storage containers 2 and along the stranding tube 1 to the stranding area 3.

  • FIG. 8 An embodiment according to the invention is shown, the holding arrangement H of which has a central area, which can be designed, for example, in the form of a plate 16 and is preferably arranged parallel to the stranding disk 5.
  • the area radially outermost with respect to the axis of rotation A is in any case within the flight circle of the good.
  • the central region is held in a support structure 10, which is located radially outside the flight circle, in a stationary and rotationally fixed manner by means of at least one holding device H2.
  • This holding device H2 comprises at least one magnetic levitation bearing, which consists of at least two magnet devices 17 and 18 located opposite one another.
  • the magnetic levitation bearings 17, 18 are preferably designed as active magnetic bearings, in which the bearing force is generated by controlled electromagnets in at least one of the magnet devices 17, 18 and the stability of the system is ensured by a suitable feedback and electronic control.
  • the constant power supply required for active magnetic bearings as well as the mechanical catch bearing, which is preferably provided for protection in the event of power failures or control system failures, usually consisting of a loose ball or slide bearing, is shown in Fig. 4 not shown. Active magnetic bearings in combination with permanent magnets are particularly advantageous. About that In addition, electrodynamic magnetic bearings with generation of the bearing force by eddy currents, mostly without electronic control, could also be provided.
  • passive magnetic bearings can of course also be used for the holding devices H2 if they are constructed using diamagnetic materials and these passive magnetic bearings are in fact realized as "superconducting magnetic bearings".
  • an air gap 19 which is preferably adjustable via the control in active magnetic bearings and which essentially extends along the flight circle of the goods.
  • This air gap 19 could also be created by an air bearing in which air under pressure forms the lubricant of the parts moving relative to one another.
  • the air gap 19 can either follow the shape of the flight circle, i.e. extend over a circumferential section of the flight circle.
  • the air gap 19 of the magnetic bearing 17, 18 of the holding device H2 also extends directly along a circumferential section of the stranding disk 5.
  • Essentially straight, plane air gaps 19 as for example for those along a circumferential section of the stranding disk 5, preferably in the lower region of the holding arrangement H.
  • the air gap 19 must of course be so large that the radial change in the distance of the material to be stranded can take place without passing through the air gap 19 when the air gap 19 enters and leaves the gap.
  • the holding arrangement H and / or the holding device H2 preferably also has at least one magnetic axial bearing in addition to the radially acting magnetic bearings described above.
  • the magnetic bearings 17, 18 can preferably be equally distributed along the circumference of the central region of the holding arrangement H. At most, arrangements with closer support of the bearing arrangement L are also conceivable in the areas in which increased loads occur, for example, due to the weight of the elements of the stranding element V. Thus, magnetic bearings 17, 18 could only be arranged below the horizontal plane through the axis of rotation A, against which lower holding devices H2 the components supported thereby are acted upon by the weight. The magnetic bearings could also be distributed in a retaining ring lying radially outside the flight circle for the fixed and rotationally fixed fixing of the central region of the holding arrangement H.
  • a stranding machine can be built up modularly, in which the number and specific design of the individual stranding elements can be selected depending on the required number and properties of the strands to be stranded. Individual stranding elements V can also be removed and / or replaced easily and quickly for maintenance and repair. Since a certain minimum number of strands to be stranded is usually to be provided, a corresponding number of stranding elements V according to the invention can be connected to one another in a rotationally fixed manner to form a jointly operable unit. This unit can also have a common drive for all stranding elements V.
  • a combination of the stranding elements described above with a conventional tube stranding machine is also conceivable.
  • the tubular stranding machine is arranged lying closest to the stranding area, while one or more stranding elements according to the invention can be connected to it.
  • the number of stranding elements V following the tube stranding machine can be chosen as desired.
  • a smaller number of these structural units can also be operated.
