Definitions

  • ABSTRACT The design of the twisting portion permits the axis of the machine rotor to be located in the vertical or inclined position.
  • the present invention relates to a wire-rope winding machine and method of its operation.
  • This invention may be utilized the wire-rope and electric-cable production industries, for example, in the production of metal cord, cable and their strands.
  • a wire-rope winding machine having a twisting portion which incorporates a frame mounting a hollow rotor on supports with at least two wire reel holders installed in the rotor along the axis thereof and kept stationary during rotation of the rotor and equipped with holder position signalizers which operate when the holder is seized by the rotor, and a rope forming die fixed on the frame coaxially with the rotor.
  • Holes are made in the side surface of the rotor to install the wire reels.
  • the number of reels depends on the type of the rope produced.
  • the rotor is rotated by means of a drive unit which is also connected to a drawing drum followed the forming die, as well as to a rope guiding mechanism and a receiving drum.
  • the wires In twisting wires to make a rope, the wires should be prevented from spinning around their axis so as to avoid structural stresses. This requirement can be met if the wire reels are kept stationary during rotation of the rotor.
  • the machines of prior art also incorporate devices for automatic cut out of the drive units.
  • this device takes the form of a vibration transducer sensible to increased vibrations, in another case it is a mercury switch whichcuts out the drive unit of the machine when the holder turns to a certain angle from its normal position.
  • the first of these devices is reacts too slow because it only indicates the result of the holder seizure, but not the commencement of the process.
  • the second device cannot be relied upon because a signal transmitted from the mercury switch to an actuator to cut out the drive unit has to go through several sets of slip rings which are unreliable in operation.
  • an object of the present invention to obviate the above disadvantages and to provide a wirerope winding machine with a twisting portion of such a design which ensures reliable and trouble-free operation of the machine and permits positioning of its rotor other than horizontal for more efficient use of the production floor area.
  • a wire-rope winding machine having a twisting portion which incorporates a frame mounting a hollow rotor on supports with at least two wire reel holders installed in the rotor along the axis thereof and kept stationary during rotation of the rotor and equipped with rotor position signalizers acting when the holder is seized by the rotor, and a rope forming die fixed on the frame coaxially with the rotor.
  • the twisting portion of the machine mounts the electromagnets with the magnetic field of each of them encompassing the corresponding reel holders, the reel holders being so positioned inside the rotor that the centre of gravity of each of them lies on the axis of the rotor which is made of non-magnetic material.
  • the holder position signalizer represents essentially two choking transducers positioned in the magnetic field of each electromagnet and electrically connected to the rotor drive unit and adapted to stop the rotation of the rotor when the holder deviates from the given position.
  • the location of the centres of gravity of the reel holders on the rotor axis excludes any centrifugal force which could destroy the machine in case the holder is seized by the rotor, i.e., the machine operation becomes trouble-free.
  • the wire-rope winding machine with a swinging portion embodied as described above to permit its operation is characterized in that the machines are positioned in two rows, while the axes of the rotors of their twisting portions are located at an angle of 0-60 to the vertical.
  • Such positioning of the rotors of the wire-rope winding machines permits a substantial reduction of the floor area occupied by the machines and an improvement in the servicing conditions.
  • FIG. 1 is a longitudinal section of the plan view of the wire-rope winding machine with a twisting portion according to the invention
  • FIG. 2 is a section along IIII in FIG. 1;
  • FIG. 3 is as FIG. 2, the holder being shown deviated from the normal position;
  • FIG. 4 is a connection diagram of the holder position transducers
  • FIG. 5 is a general view of the wire-rope winding machine, showing one version of the embodiment of the holder position signalizer
  • FIG. 6 is a general view of the wire-rope winding machines with the twisting portions thereof installed vertically;
  • FIG. 7 is a view along arrow IIII in FIG. 6'
  • FIG. 8 is sectional view along III-III in FIG. 7.
  • FIG. 9 is a side view of the wire-rope winding machines whose twisting portions are angled to the vertical.
  • the wire-rope winding machine has a twisting portion which incorporates a rotor 1 representing essentially a cylindrical shell 2 whose ends are closed with covers 3.
  • the axles 6 of the holders 7 are hollow to draw the wire 9 off the corresponding reel 8.
  • Ceramic rings 10 Fixed on the surface of the shell 2 of the rotor 1 along the generating line of the shell are ceramic rings 10 serving as guides for the wire 9 delivered out of the axle 6 of the holder 7 of each reel 8.
  • axles ll of the rotor l which are housed in bearings 12 installed in supports 13.
  • a drawing drum I8 is provided to draw the rope 16 out of the die 17. Disposed after the drawing drum 18 is a guiding mechanism 19 to place the rope 16 on a receiving drum 20.
  • the rotor l, the drawing drum 18, the rope guiding mechanism 19 and the receiving drum 20 are installed on the frame 14 and are operated from a common drive unit 21 with which they are kinematically linked.
  • Each holder 7 with the reel 8 is so installed in the rotor 1 that their common centre of gravity lies on the axis of the rotor 1. Due to this arrangement, no destructive centrifugal force occurs which would destroy the machine in case of failure or jamming of the bearings 5 wherein the holder 7 is mounted, or if the holder 7 is seized by the rotating rotor l.
  • the technology of making the rope 16 requires that to prevent spinning of the wire 9 along its axis each holder 7 should remain stationary during rotation of the rotor 1.
  • an electromagnet 22 is installed on the frame 14 beyond the rotor l for each individual holder 7.
  • the magnetic field of each electromagnet 22 encompasses the corresponding holder 7 to restrain it from rotating when the rotor 1 is in motion.
  • the shell 2 of the rotor I is made of a non-magnetic material, such as fibreglass plastic.
  • the electromagnets 22 are energized from an alternating current mains or a direct current source (not shown in the drawing).
  • An actuator 24 is connected to the choking transducers 23 via a transformer 25.
  • the choking transducers 23 are connected to each other to form two arms of a differential bridge.
  • the primary winding of the transformer 25 is connected to another two arms of the differential bridge.
  • the transducers 23 via the transformer 25 are wired to the actuator 24 which cut out the drive unit 21 to stop the rotation of the rotor 1 if the holder 7 is captured by the rotor.
  • a source of alternating current (not shown in the drawing) energizing the transducers 23 is connected to the bridge diagonal via a transformer 26.
  • the position signalizer of the holder 7 may also take the form of a radiant energy emitter 27 (FIG. 5) and a detector 28 which both are installed on a common axis parallel to the axis of the rotor l, and a number of discs 29 with a hole 30 rigidly fastened to each holder 7.
  • the hole 30 made in each disc 29 is disposed in the beam path.
  • the herein disclosed wire-rope winding machine with a swinging portion allows the rotor l of the machine to be positioned so that the rotor axis occupies any other than horizontal position for convenient servicing of the machine under actual production conditions.
  • the disclosed design of the twisting portion of the machine permits the rotor l to be installed so that its axis is located at an angle of 0 to 60 to the vertical.
  • FIGS. 6 and 7 show the wire-rope winding machines with the rotors 1 installed vertically in two rows. This makes it possible to reduce the production floor area accupied by the machines l0l5 times compared with the area occupied by known machines.
  • One more advantage of this arrangement is associated with the convenient servicing of the machines which permits a single workman to attend a considerable number of machines with a corresponding increase in of the labour productivity.
  • FIG. 9 illustrates the machines whose swinging portions are so installed that their rotors l are angled to the vertical.
  • the arrangement is more preferable for the machines incorporating heavy reels 8 whose installation into the holders 7 requires special handling facilities.
  • the wire-rope winding machine operates as follows.
  • the electromagnets 22 Prior to cutting in the drive unit 21 of the machine, the electromagnets 22 are switched on and simultaneously the power source of the transducers 23 is also switched on.
  • the shell 2 of the rotor 1 does not screen the magnetic field of the electromagnets 22 because the shell is made of fibreglass plastic.
  • Rotation of the rotor l is thus initiated, drawing drum l8 and receiving drum 20, and the motion of the mechanism 19 guides the rope 16 so that it is taken up by the receiving drum 20.
  • the holders 7 of the reels 8 remain stationary when the rotor l is in rotation.
  • the wire 9 does not spin around its axis. Amperage of the power source of the electromagnet 22 should be appropriately chosen so that the magnetic-field intensity set up of the electromagnet 22 is enough to generate a torque in excess of the frictional moment in the bearings 5 of the holder 7.
  • the wire 9 is continuously delivered from each reel 8 through the axle 6 of the holder-7 intothe corresponding ceramic rings 10 and the holes in the axle ll of the rotor l toward the forming die 17.
  • the completed rope 16 is brought to the drawing drum 18, wherefrom via the guiding mechanism 19 it is collected on the receiving drum.
  • the unbalanced bridge condition causes the secondary winding of the transformer 25 to be energised which sets the actuator 24 in operation to cut out the drive unit 21 of the wire-rope winding machine.
  • a beam produced by the emitter 27 is brought to the detector 28 through the holes 30 made in the discs 29 which are fastened to the reel holders.
  • the radiant energy detector 28 sends a signal to cut out the drive unit 21 of the machine and the rotation of the rotor l ceases.
  • the wire-rope winding machine with a twisting portion according to the present invention is reliable and safe in operation and at vertical or inclined positioning of the rotors 1 it becomes possible to substantially reduce the production floor area occupied by the wiremaking equipment and increase labour productivity.
