Definitions

  • the cutting of electric cables, intended to be placed, independently or in a bundle, in appropriate conduits, is generally carried out on a work area, the markings of which allow the cables supplied to be cut to length by a coil park located nearby. This operation requires several workers to ensure the choice of cable, its unwinding to the desired length, sectioning, tracking, possible booting, winding and shifting to a storage location.
  • the object of the invention is a method allowing the mechanization of the various phases of manipulation and handling described above and of facilitating and simplifying the task of the personnel.
  • the method for manufacturing electrical installations according to the present invention is characterized in that the operation of cutting electrical cables comprises, located at a work station, threading a free end of each cable through a measuring device length when running and through a sectioning device, the measuring device producing a control signal when a determined, adjustable length of the cable has passed through the measuring device, fixing the free end of each electric cable in pliers suspended from an endless chain or cable tensioned on two pulleys, one of which is motorized, the motorized pulley is driven and stopped by means of said control signal, the remote release of the pinched end of the electric cable actuated by said control signal, the sectioning of the cable by the disconnecting device actuated by said control signal and the return of the empty clamp to the work station.
  • the object of the invention is also an installation for cutting cables for the execution of this process, characterized in that it comprises, at the place of a work station, a device for measuring the length of the movement of an electric cable to be cut producing a control signal when a determined adjustable length of the cable is reached, two pulleys, one idle, the other driving, arranged at a certain distance from each other, a device drive whose stop is controlled by the signal delivered by the measuring device, an endless chain or cable allowing the attachment of one end of an electric cable to be cut, a remote control device for the opening of the clamp actuated by said command signal, and a cable cutting device at the place of the work station, actuated by said command signal.
  • FIG. 1 of which represents a perspective view of an installation and of which FIG. 2 shows a clamp also in perspective.
  • Figure 1 shows, in perspective, the entire installation for cutting to a fixed length, an electric cable 1 unwound from a reel 2, installed upstream.
  • C reel is equipped with a braking device comprising a pneumatic or hydraulic cylinder J3 remotely controlled and a shoe 4, integral with the reel 2, which on command prevents the reel from continuing its rotational movement and unwinding a hindering cable excess the smooth running of the installation when this braking device is actuated.
  • a braking device comprising a pneumatic or hydraulic cylinder J3 remotely controlled and a shoe 4, integral with the reel 2, which on command prevents the reel from continuing its rotational movement and unwinding a hindering cable excess the smooth running of the installation when this braking device is actuated.
  • the free end of the electric cable 1, chosen for cutting is first engaged in a running length measurement device 5, equipped with a counter and producing a control signal as soon as the length pre-selected on the measuring device 5 is reached.
  • This device 5 is mounted on a hinge to facilitate the introduction of the first end of cable which, after its placement in the measuring device, is then threaded into a device for cutting 6, in the normally open position, and whose shears close following the emission of a control signal by the measuring device 5.
  • the measuring device 5 and the cutting device are combined in a work station 7.
  • the cutting installation also includes two pulleys, one driven 8, the other idler 9, each mounted on a vertical axis and equipped at its base with a bevelled flange 10 intended to ensure the correct maintenance of a clamp. 11 during its passage over these pulleys.
  • the idler pulley has the distinction of being coaxial with a frusto-conical skirt 12 pivoting independently of the idler pulley and used for returning the electric cable 1 driven by the clamp 11 when the length of the cable to be cut exceeds the distance between the two pulleys 8 and 9.
  • the two pulleys 8 and 9 support an endless chain or cable 15 whose two ends are fixed to the clamp II and whose tension can vary by a slight modification of the spacing of the pulleys 8 and 9 obtained, in this case , by the movement of a mobile carriage 13 supporting the pulley 8, under the action of a pneumatic or hydraulic cylinder 14 controlled from the work station 7.
  • FIG. 2 represents an exemplary embodiment of the clamp 11.
  • the two ends of the endless cable 15 are fixed respectively on one side to an element 16 and on the other side to an element 17 of the clamp I1.
  • the element 16 is integral with a sliding part 18 inside a tubular profile 19 integral with the element 17.
  • the sliding part 18 has an oblique jaw 20 while the tubular profile 19 has a jaw 21 facing to the jaw 20 of part 18.
  • the element 16 is integral with an axis 23 on which slides the element 17 and at the end of which is threaded a helical spring 22 which pushes the element 17 against the element 16.
  • the maximum approximation of the elements 16 and 17 corresponds to the maximum opening of the jaws 20 and 21.
  • the idler pulley 9 is provided by a springboard 26 located near the idler pulley 9 and whose height corresponds roughly to the level of the bottom of the frustoconical skirt 12.
  • the control signal emitted by the measuring device 5 stops the drive motor 24 and thus immobilizes the part I1 at a distance from the cutting device 6 corresponding to the predetermined length for the electric cable to be cut 1. Simultaneously the control signal emitted by the measuring device 5 controls the jack 3 of the braking device of the reel 2 and with a certain delay opens the jaws 20 and 21 of the clamp 11 via the jack 14 and the carriage 13 which supports the driving pulley 8 and reduces the tension of the strands of the endless cable 15 by slightly bringing the pulleys 8 and 9 together.
  • This remote control of the opening of the clamp 11 by the control signal emitted by the device 5 has the advantage of not requiring any control member in the path of the clamp 11.
  • the oscillating mounting of the cutting device 6 allows the passage of the clamp II when taking a new cable.
  • the jack 14 After a short time, during which the endless cable or chain remains relaxed, the jack 14 again re-establishes the tension of the cable 15 and starts the motor 24 to bring the clamp 11 back to the starting position detected for example by a switch of limit switch, not shown. At this time, the motor 24 is again stopped and the jack 14 is actuated to relax the cable 15 and open the clamp 11.
