Definitions

  • the present invention concerns an apparatus for twisting and winding of wire onto a spool and comprising at least one externally driven swing arm shaft to which radially protruding control means are secured for guiding and twisting the wire, as well as a suspended cradle which comprises a wire spool onto which the wire is wound by means of a traversing mechanism, and which is driven by a hydrostatic transmission arranged in the cradle and comprising a hydraulic motor, a pump, a regulating valve, and hydraulic medium tank which are driven by the swing arm shaft.
  • the object of the invention is to provide an apparatus of the type mentioned in the opening paragraph which prevents the above-mentioned heat drawbacks, and which ensures sufficient tensioning of the wound wire during start and stop as well as in continuos operation.
  • Another object of the invention is to provide an apparatus which is at least just as compact as the known structures.
  • the apparatus of the present invention is characterised in that the hydraulic pump is adapted to perform variable displacement of the hydrostatic medium during the wining operation by the control of the regulating valve in response to the tension of the wire.
  • variable hydrostatic transmission ensures that the apparatus maybe controlled such that it always just supplies the necessary amount of oil to the hydraulic motor for it to maintain the pressure and the wire tension which corresponds to the setting of the pressure regulating valve. Thus, no excess oil is converted into heat. Further, the variable hydrostatic transmission ensures that the hydraulic motor receives a sufficient amount of oil at both the start and the stop phases. This provides correct wire tension from the moment when the hydrostatic transmission is activated through the swing arm shaft, which means that the wire is wound while being pulled into the cradle.
  • variable hydrostatic transmission supplies precisely the amount of oil which is sufficient for the wire to be wound with a suitable tension.
  • the hydrostatic system is controlled by a valve.
  • wire in this connection covers all types of wire-shaped objects, such as e.g. yarn, rope, plastics fibres, tapes, lines, cables, steel wires, etc.
  • the hydraulic pump is adapted to perform variable displacement of the hydrostatic medium during the winding operation, while the hydraulic motor has a fixed displacement.
  • the displacement of the hydrostatic medium may be adjusted.
  • the hydraulic motor is adapted to perform variable displacement of the hydrostatic medium during the winding operation, while the hydraulic pump may have either a fixed or a variable displacement. Combination of both regulating possibilities provides a hydraulic transmission with variable power and variable moment.
  • the hydrostatic transmission is controlled by a valve which detects the wound wire spool diameter by means of a diameter detecting device.
  • the displacement in the hydrostatic transmission may hereby be regulated in response to the wire spool diameter, and controlled and sufficient tension of the wire is achieved.
  • the radially protruding control means are provided as two outwardly directed arms for twisting the wire.
  • the wire hereby obtains two twists per rotation of the swing arms. This type of device is known under the designation two for one twister.
  • the radially protruding control means are provided as four outwardly directed arms for twisting the wire.
  • the wire hereby obtains four twists per rotatation of the swing arms.
  • This type of apparatus is known under the designation four for one twister.
  • the radially protruding control means may comprise circular elements, whereby, depending on the number, in the same manner as described above, different numbers of twists of the wire per rotation can be obtained.
  • Fig. 1 shows the structure of the two for one twister apparatus type for twisting and winding wire.
  • the apparatus shown in fig. 1 for twisting and winding wire onto a spool comprises two externally driven swing arm shafts 21, 22 having secured thereto two radially protruding control means which are constructed as outwardly directed swing arms 3, 10 for guiding and twisting the wire 1.
  • a cradle 20 is suspended from the swing arm shafts 21, 22, comprising a wire spool 6 onto which the wire 1 is wound by means of a traversing mechanism 5, and which is driven via a hydrostatic transmission, which is arranged in the cradle and comprises a hydraulic motor 17 and a pump 14 which are driven by the swing arm shaft 21.
  • the cradle 20 comprises a balance weight 18 which prevents the cradle 20 from revolving.
  • the wire 1, which is to be twisted and wound, is first run around brake rollers 2 and into a bored swing arm shaft 22. Then the wire is run around a first swing arm 3, around a second swing arm 10, in through the second bored swing arm shaft 21 and further on into the cradle 20. Rotation of the swing arms 3 and 10 causes the wire 1 to follow a "balloon" path around the cradle 20. To prevent the balloon 4 from getting too big, it is controlled by the brake rollers 2.
  • the swing arms 3 and 10 are synchronized by means of toothed belt drives 11 and a transmission shaft 15 and are driven by an electric motor 13 via the drive 12.
  • the yarn now twisted is pulled forward in the cradle by means of pull rollers 7, which are synchronized with the swing arms 3 and 10 via the drives 8 and 9.
  • the ratio of the speed of the pull rollers 7 to the speed of the swing arms determines the applied number of twists per length unit of the wire.
  • the pull speed of the wire is constant and depends on the speed of the pull rollers 7.
  • the wire is wound onto a spool 6 via a traversing device 5.
  • the wire spool 6 rotates at a decreasing speed as the spool diameter increases, and it is driven together with the traversing device 5 by a hydraulic motor 17.
  • the hydraulic motor 17 is fed by a hydraulic pump 14, which is controlled by a regulating valve 16 and is driven by the swing arm shaft 21 through a belt drive.
  • the hydraulic pump draws oil from a tank 23 which is built into the cradle 20.
  • the regulating valve 16 is controlled by a diameter detecting device 19 which detects the wound wire core diameter. It is noted that the diameter detecting device is not necessary according to the invention, as the regulating valve 16 may be controlled in another manner, e.g. via a device which measures the tension of the wire. Likewise, the diameter detecting device 19 may be constructed in many other ways.
  • the hydraulic pump provides a maximum flow until the pre-set pressure has been reached.
  • the hydraulic pump supplies precisely the amount of oil which is necessary to maintain the desired pressure, which is regulated by means of the regulating valve 16.
  • the hydraulic pump 14 is caused to feed the hydraulic motor 17 with the amount of oil necessary to maintain the pre-set pressure.
  • the hydraulic pump 17 has to supply an additional amount of oil to compensate for leakage in the hydraulic motor 17 at low revolutions.
  • the invention is also applicable to four for one twisters, where winding takes place in the cradle by means of a hydraulic device.
  • four swing arms may be provided, running in opposite directions in pairs.
  • other forms of radially protruding control means than swing arms may be used.
  • it will e.g. be possible to use substantially circular or elliptical control means which are secured to the swing arm shaft.
  • the invention may be used for other types of devices for winding of wire, etc.
  • a pump with variable displacement instead of a pump with variable displacement, a motor with variable displacement or a both a pump and a motor with variable displacement may be used within the scope of the invention.
  • the hydrostatic medium preferably comprises oil, but also other liquids may be used.
