Definitions

  • the invention relates to an alternating twist stranding machine for stranding Rope elements of larger cross-section, preferably deviating from the circular shape, in particular a circular sector-shaped cross section, with a stranding head to which the individual rope elements are fed from a swirl accumulator, preferably in Direction of movement of the rope elements after the stranding head a tape take-off is provided.
  • Alternating twist stranding machines are used to manufacture rope bandages used, the individual rope elements alternately to the right and to the left be twisted.
  • the advantage of such alternating stranding machines is that the individual rope elements of stationary, so not one in the direction of movement Rope elements extending axis rotating drums can be withdrawn and that the rope bandage can be wound on a stationary drum, whereby the construction is significantly simplified.
  • the stranding head consists of a rope elements with small, circular cross sections alternating to a reciprocating rotary motion driven cylinder on has grooves in the surface in which the individual cable elements are guided. Of the end face of the cylinder on the outlet side, the rope elements run over rounded edges to the stranding point, where the rope structure is caused by the alternating rotation of the stranding head is formed.
  • the individual rope elements are fed to the stranding head via a so-called swirl memory, which prevents the rope elements in the back and forth the resulting rotary movement of the stranding head touch each other and thereby large Cause frictional forces that could hinder the stranding process.
  • Such Known swirl accumulators consist, for example, of rope elements penetrated by them Tubes or from openings for passing the rope elements Disks that are rotatably mounted on their circumference.
  • the rope formation formed in the stranding point is usually from a tape pull added, which prevents that when changing the direction of rotation The rope bandage opens again.
  • the cross section is, for example, circular sector-shaped, so that from several rope elements a rope bandage with a completely filled round cross-section is formed, it is additionally necessary to ensure that when stranding the individual rope elements occupy a certain position relative to each other, for which a additional twisting of the individual rope elements is required.
  • the present invention has for its object a Change twist stranding machine of the type described in the introduction so that a Stranding of rope elements of larger cross-section is possible without damage and that with rope elements with a cross-section deviating from the circular shape, in particular with circular sector-shaped cross-section, the required position of the individual rope elements Formation of the rope association is always guaranteed.
  • the Invention before that the stranding head from at least three with their center around one common axis extending in the direction of movement of the rope elements rotatable stored and driven to an alternating reciprocating rotary motion
  • disks which are provided with openings through which the cable elements pass, the two outer disks being driven at a smaller angle of rotation than that middle disc (s) lying between these outer discs.
  • Alternating twist stranding machine drives the disks from a common one Shaft over belts, preferably toothed belts, over chains or the like, being in the drive of the two outer discs transmission elements are switched on, one delayed start and / or premature termination of the rotary motion at one Reverse direction of rotation.
  • the shaft is rotatably connected to a drive member which via the elastic elements with a wheel rotatably mounted on the shaft, preferably a gear, is in drive connection, which is an outer via the belt Disc drives.
  • the shaft is rotatably connected to the driver, the at least one recess has, whose opposite walls stops for a parallel to the shaft axis form running bolt, which of a wheel rotatably mounted on the shaft, preferably a gear, which protrudes an outer disc over the belt drives.
  • the number of guide rollers also corresponds to the respective one Select cross-sectional shape of the rope elements.
  • a circular sector cross-section For example, three such guide rollers are to be provided.
  • the guide rollers can also be within the limit of the openings be provided. However, it is useful if the guide rollers on the in Direction of movement of the rope elements are arranged front side of the disks, because this simplifies the construction.
  • the guide rollers are preferably on the Front of the discs rotatably mounted.
  • the storage at least one of the guide rollers assigned to an opening is adjustable.
  • the Rope elements after the last sheave one out of two enclosing the rope structure Tapes provided existing tape take-off, the tapes being attached to the rope bandage turned side with projections, preferably in the form of a in the longitudinal direction of the tape running V-belts are provided, which engage in grooves of belt support rollers. This means that when stranding rope elements with a circular shape deviating cross-section in the strip take-off occurring considerable lateral forces optimal added.
  • FIG. 1 shows a side view of the invention Alternating stranding machine.
  • Fig.2 shows an end view of an outer disk of the Fig.3 shows a section along the line III-III and Fig.4 shows a section the line IV-IV in Fig.1.
  • 5 shows a cross section through the tape take-off along the line V-V in Fig.1.
  • the alternating twist stranding machine has a stranding head 1 and a tape take-off 2.
  • a stranding head 1 In the direction of movement 3 of the individual rope elements 4 before Stranding head 1 is provided, which prevents swirl storage, not shown is that the rope elements supplied to the stranding head touch each other and thereby hinder the stranding process.
  • the stranding head 1 consists of four rotatably mounted about a common axis 5 Disks, namely from the two outer disks 6,7 and from, in the illustrated Embodiment two, middle disks 8. But it can also only be a middle one Disk 8 may be provided, or more than two middle disks 8 may also be used be arranged.
  • the disks 6, 7, 8 are driven in the manner described in more detail below Way via toothed belt 9, the gears 10 connected to the pulleys 6,7,8 comb.
  • the disks 6, 7, 8 have openings 11 which a cross section corresponding to the cross section of the rope elements 4 to be stranded, have a circular sector-shaped cross section in the illustrated embodiment.
  • guide rollers 13, 14 are rotatably mounted, which are arranged and designed such that they have the cross section of the cable elements 4 support.
  • the supporting the flanks of the circular sector-shaped cross section Guide rollers 13 have a flat contact surface, which is the circular arc supporting contact surface of the guide roller 14 is concave. Is expedient at least the bearing of the guide roller 14 is adjustable to adapt to to enable different cross-sectional sizes.
  • Fig.2 only 11 guide rollers are shown in the region of one of the openings. Of course, all openings 11 are provided with such guide rollers.
  • the middle disks 8 are driven directly from a shaft 16 via this Shaft 16 wedged gears 17 which mesh with the toothed belt 9 mentioned.
  • the the two outer disks 6,7 are driven to a smaller angle of rotation than the middle discs 8, so that it is ensured that the rotation of the individual Rope elements 4 in the stranding head 1 take place along a continuous curve without break points and damage to the cable elements or the insulation thereof is prevented.
  • the outer disk 6 is driven via a shaft 16 which is rotatable stored gear 18 and a toothed belt cooperating with this gear 18 9. From the gear 18 are parallel to the axis of the shaft 16 extending bolts 19, which in Recesses 20 of a driver 21 connected in a rotationally fixed manner to the shaft 16 protrude into it. The lateral boundaries 22 of the recesses 20 form stops for the bolts 19.
  • the shaft 16 alternates into a reciprocating rotary movement driven.
  • the bolt 19 moves within the Recess 20 of the driver 21 until it is on the opposite side Boundary 22 of this recess 20 comes to rest. Only then is the bolt 19 the gear 18 and thus the disc 6 is rotated, so that after each reversal of the direction of rotation of the shaft 16 is a delayed start of the rotational movement of the Disc 6 is done.
  • the disk 7 is driven by elastic rubber buffers 23, which are on the one hand on lugs 24 of a drive member 25 connected in a rotationally fixed manner to the shaft 16, on the other hand, support on a shoulder 26 of a gearwheel 27 which is on the shaft 16 is rotatably mounted and meshes with the toothed belt 9.
  • the gear 27 has stops 28 on which the rotational movement, that is to say the rotational angle to be carried out by the gear 27, limit.
  • the tape take-off 2 shown in FIG. 5 consists of two the cable assembly 29 enclosing tapes 30, which on their side facing away from the cable assembly 29 Provide projections 31 in the form of a V-belt running in the longitudinal direction of the belt are, which engages in grooves 32 of tape support rollers 33. This ensures that the considerable transverse forces arising during the stranding process from the tapes 30 be optimally absorbed.
