Definitions

  • the present invention relates to a machine for winding, at a very short pitch, on a cable, at least one metallic armouring wire, comprising a first means for moving a rectilinear portion of the cable in translation along its axis and at least one coil. distribution of said wire arranged on a reel holder subjected to rotate around the cable in a plane perpendicular to said axis, the wire passing over a grooved pulley disposed between the reel and the cable and fixed axis relative to the reel.
  • Machines of this type which essentially comprise means for moving in translation along its axis a rectilinear part of the cable, and at least one spool for distributing said wire subject to rotate around said rectilinear part of the cable in a plane perpendicular to said axis.
  • the wire is unwound from the spool and driven by the traction exerted by the cable itself during its advancement.
  • the machine described above cannot be used. Indeed, the tightening effect of metal wires (6 to 7 mm in diameter or more) on the cable is considerable and would crush the lead. This would result in folds of the lead sheath causing irregularities in the insulation and which could cause the cable to snap during use.
  • Document DE-C-394 934 describes a machine for stranding the conductive wires of an electric cable comprising a reel holder rotated at a determined speed, coils of conductive wires carried by this reel holder, and pulleys of control of the advance speed of the rotating wire at a speed multiple of that of the spool holder.
  • the wire feed speed can only be changed by stopping the machine and changing the transmission gears from the rotation of the spool holder to the pulleys. It does not make it possible to modify the speed of advance of the thread during the operation of the machine, which can lead to too strong tension or to insufficient tension of the thread.
  • the object of the present invention is to allow correct fitting of the armor wires of a cable, while constantly maintaining a good tension of the wires during the operation of the machine and a regular pitch of the helical armor.
  • the machine according to the invention is characterized in that the pulley is provided with a drive means for rotation at an adjustable speed, independently of the speed of rotation of the reel holder.
  • the pulley drive means comprises a drum, coaxial with the spool holder and driven by a motor associated with a variable speed drive, said drum carrying a toothed ring coaxial with the drum and driving a sprocket of a chain axis integral with the reel holder, said pinion being integral in rotation with said pulley.
  • the cable to be armed is designated by the reference 1. It is driven in a translational movement in the direction of the arrow and, after receiving the armor wires on a part made rectilinear, it s' wind on a capstan 2, then on a reel not shown.
  • the winding of the armor metal wires is produced, as is well known, by rotation, around the straight part of the cable, of a set of 3 reel holders.
  • the winding of the armor metal wires is produced, as is well known, by rotation, around the straight part of the cable, of a set of 3 reel holders.
  • Only two coils 4 have been shown, but it should be understood that there are several coils, for example sixteen, regularly distributed around the assembly 3 to which they are fixed.
  • the wire 5 exits from the spool 4 and passes over pulleys 6 and 8.
  • the assembly 3 is rotated by a motor 9 driving, by a pinion 10, a toothed crown 11 surrounding the assembly 3.
  • Line 12 in dashed lines symbolizes the synchronism existing between the movement of the capstan, therefore the speed of translation of the cable, and the speed of rotation of the reel holder assembly 3.
  • the pulley is driven by a drum 15, coaxial with the rectilinear part of the cable and inside the set of 3 reel holders.
  • This drum is rotated by the motor 9 by a ring gear 16, cooperating with the pinions 17, 18 and 19.
  • a speed controller 20 is interposed between the pinions 17 and 18. Its role will be explained later.
  • a ring gear 21, at the end of the drum 15 located on the drum side, allows the pulley 8 to be driven by means of a chain 22, a pinion 23 and a bevel gear 24.
  • the chain link between the ring gear and the pinion 23 will be explained later, with reference to FIG. 2.
  • the rotation of the pulley 8, in synchronism with the reel holder, ensures by friction the movement of the wire, such. so that the tension of the wire on the cable is acceptable by the latter.
  • This thread tension is measured using a sensor 25. If the thread tension is too high, the speed controller 20 is used to increase the angular speed of the drum and therefore that of the pulley 8.
  • a pressure roller 26 holds the wire 5 in the groove of the pulley 8; this groove, of triangular profile, allows friction therefore a more or less strong drive of the wire depending on whether it goes more or less quickly compared to the correct speed. There is therefore “self-regulation”.
  • FIG. 2 is a partial end view of a machine having sixteen bobbin carriers.
  • Toothed wheels 33, 33A, 338, ..., 33G serve as references for the chain 22; at least one of these wheels, here the wheel 33, has a movable shaft to allow the chain tension to be adjusted (the dashed lines show another position of the chain and the wheel 33).
  • the indications of the wire tension sensor 25 control the speed of the control motor: acting on the variator 20 independently of the main motor 9.
