Definitions

  • the invention relates to a plant for stranding a Strand of strands on a rope core, according to the generic term of Claim 1.
  • Such a twisting plant for the production of a turned Seils is known for example from DE 196 48 257 A1.
  • a winch rope is made over two aramid yarn spinners, a first layer made by a spinner tensile yarns impregnated with bitumen and with swelling yarns is wrapped before using this rope core a second spinner an outer second layer from tensile strength Yarn is spun.
  • Analog can be used with one described known rope plant also in Continuous process around an outermost layer of synthetic fiber strands a sheathed rope core can be wound, which as prefabricated semi-finished product supplied to the rope installation becomes.
  • Such rope extensions are particularly in the case of synthetic fiber ropes, which run as driven elevator ropes over a rope sheave and by an elevator car and a corresponding one Counterweight loads are disruptive. They require about that Operating time considers a repeated shortening of the ropes to the respective floor level, which is complex and expensive unwanted costs. In isolated cases can stretch when running over the traction sheave Remove the cover from the outer layer, under Stress caused by a change in the cross-section of the rope subsequent flow of the intermediate jacket.
  • the invention is therefore based on the problem, one at the beginning to show the mentioned rope plant with which a rope with Rope core sheathing can be produced, which over the entire service life largely free of design-related Stretch is. This is described by that in claim 1 Plant part or that described in claim 9 Process step realized.
  • Rope plant can be achieved with a heater in that the strands twist into the in plastifzbare state offset casing insert thermoplastic material while doing the emerging gusset with the excess, repressed Fill thermoplastic. This plastic deformation makes it Rope structure in a state as it is more conventional would only set after a long period of operation.
  • An inventive Heater can be used in conventional stranding plants can be retrofitted, thereby reducing the device costs and customer acceptance will be increased.
  • the heating device can be designed as a continuous furnace, which has the advantage that the rope core sheathing over a large process line evenly and in the desired Jacket thickness can be heated to plasticizing temperature.
  • a preferred embodiment with a microwave heating device enables easy control of the softening process.
  • the Sheathing is plasticized while surrounding Device parts are not heated. So you can on a Heat shielding or insulation of the heating device waived compared to the stranding device and additionally Costs can be saved.
  • the Heater two heaters which in Direction of conveyance of the rope core are arranged one behind the other.
  • the rear, second heater is directly in front of one Stranded perforated disc of the stranding device placed. It forms on the rope core sheathing immediately before the stranding point, where the strands run onto the rope core a temperature maximum out.
  • the thermal energy generated by the second heater can be specifically controlled in intensity.
  • the warming or the softening of the rope core can be done in two stages be carried out what advantages in the Plasticization temperature control offers. In a continuous furnace or in the microwave heater, the jacket evenly raised to the plasticizing temperature level and in the subsequent, second heating device, the Thermoplastic then specifically to the desired depth melted and thus on the subsequent stranding prepared.
  • Another advantage is that through this additional heating device the strands soaked in resin can be more easily brought into their spiral shape. This are then stress-free in the rope structure. From energetic Reasons and in particular to prematurely cool down the Delaying sheathing is the second heater a preferred embodiment partially between the Stranding device and the stranding disk arranged.
  • the advantages of a second heating device which according to one Another preferred embodiment of the invention hot air blower used, the hot air flows with the help of a Flow funnel just before the stranding point on the rope sheath be merged, consist in the so achieved Arrangement of large-volume device part, such as the Blower, at a lateral distance from the rope core and the Stranding necessary device parts. This builds the Overall heater is compact and energy saving also easier to retrofit in existing systems.
  • An advantageous embodiment of the flow guide device is to train them as flow funnels.
  • the flow funnel surrounds the rope core coaxially, in the conveying direction divergent and the rope core through the divergent end runs directly into the stranded hole disc.
  • the Flow funnel covers the stranding device in one Running section of the strands to be stranded before the stranding point. This also allows the strands of the through the Hot air flowing around the fan and flows around the funnel be heated. This in turn has an effect on premature cooling against the plastically formable rope core sheathing and extends the plastic flow under the Lacing strength of the freshly stranded strand.
  • the compression device can expediently have four Cartesian pressure rollers include, by their Interact with a symmetrically compressed rope structure particularly small cross section can be produced.
  • Fig. 1, 1 is a system for stranding a strand of strands on a sheathed with a thermoplastic Rope core 2 designated.
  • the rope core 2 is in this Example of tensile strengths stranded together in several layers Aramid fiber strands 3, 4 and is of an abrasion-resistant sheath, preferably surrounded by polyurethane or polyamide.
  • the rope core sheathing can be made from any other abrasion-resistant plastic material are made; However, a thermoplastic is essential to the invention Material behavior.
  • the rope core 2 instead of Aramid fiber strands 3.4 also from other synthetic or Chemical fiber strands or made of wire strands.
  • the rope core 2 covered here with polyurethane Aramid fiber strands 3.4 is a prefabricated semi-finished product a rope core roll 5 in a not shown here Carrier device on the entry side of the rope plant 1 mounted.
