  • the generally annular wrapping nose 102 is rotatably mounted within a ring bearing 108 which is mounted on a support 110 secured to a bed plate 112 which serves as a foundation member for the entire machine 100.
  • the generally cylindrical first wire-supplying section 104 is rotatably mounted at its front end (the left end as viewed in Figure 1) by being mechanically coupled to the wrapping nose 102.
  • the first section 104 is rotatably mounted at its rear end (the right end as viewed in Figure 1) by means of a ring bearing 114 mounted on a support 116 detachably secured to the bed plate 112.
  • the generally cylindrical second wire- supplying section 106 is rotatably mounted at its front end (the left end as viewed in Figure 1) within the bearing 114 and is mechanically coupled (in operation) to the rear of the first section 104.
  • the second section 106 is rotatably mounted at its rear end (the right end as viewed in Figure 1) by means of a ring bearing 118 mounted on a support 120 detachably secured to the bed plate 112.
  • the first wire-supplying section 104 differs from the second wire-supplying section 106 in certain respects which will subsequently be detailed. Further wire- supplying sections (if any) are essentially the same as the second wire-supplying section 106, and are supported and coupled in the same manner as is the second section 106.
  • the exterior of the first wire-supplying section 104 supports a plurality of annular reels 122, shown by way of example as five in number.
  • the reels 122 are coaxial with the longitudinal axis 124 of the machine 100, and the reels 122 are made rotatable with respect to the main body of the section 104 by the interposition of eight longitudinally aligned nylon rollers 126 circumferentially distributed around the periphery of the main body, each roller 126 being set in a respective longitudinal groove.
  • each adjacent pair of reels 122 and between the outer faces of end reels on the section 104 and adjacent flanges on the periphery of the section 104, are respective rows of circumferentially distributed nylon rollers 128 each of which has a respective axis of rotation which is radial with respect to the longitudinal axis 124.
  • the rollers 128 sustain axial thrusts incurred by the reels 122 during paying-out of wire, and facilitate relative rotation of the reels with respect to each other and with respect to the main body of the section 104.
  • Each of the reels 128 has an associated wire take-up and guidance tube 130 (only one of which is shown in Figures 1 and 2).
  • Each of the tubes 130 is fixed to the main body of the first section 104, with the inlet end of each of the tubes 130 adjacent a respective one of the reels 122 and the outlet ends of the tubes 130 being connected to a respective one of a circular array of wire feed holes 132 in the forward end of the section 104 (see Figure 3).
  • Each of the tubes 130 takes up wire 134 previously wound on the respective reel 122 and guides the taken-up wire to the respective feed hole 132 for transfer to the wrapping nose 102 (as will be detailed subsequently) .
  • this maximum number less the number of reels 122 and guide tubes 130 on the first section 104, is the number of feed holes 132 that are extended longitudinally through the first section 104 to the rear of the section 104 (see Figure 4) where they couple to corresponding feed tubes in the second section 106 (see Figure 1).
  • the second section 106 has an array of rotatably mounted reels, together with wire take-up and guidance tubes, that is basically similar to the first section 104, but which differs in certain respects now to be detailed.
  • wires 134' from the second and subsequent wire-supplying sections are led through an outer part 136 of the main body of the first section 104, and over a longitudinally grooved inner sleeve 138 forming another part of the main body of the first section 104.
  • the inner sleeve 138 is slid into the outer part 136 to complete the assembly and reeving of the first wire-supplying section 104.
  • the second wire- supplying section 106 lacks the inner sleeve 138 of the first section 104, the wires from third and subsequent wire-supplying sections (not shown) being carried through the body of the second section 106 by means of a circumferentially distributed array of longitudinal inner guide tubes 140.
  • Other components of the second section 106 which are identical or functionally equivalent to parts of the first section 104 are given the same reference numerals.
  • Another and relatively minor technical distinction with respect to the first section 104 is that in the second section 106, the rollers 128 are substituted by anti-friction spacer discs 142.
  • FIG 8, 9 and 10 show essential features of the wrapping nose 102 to an enlarged scale with respect to Figure 1.
  • Wires 134 passing out of the forward ends of the guide tubes 130 by way of the wire feed holes 132 ( Figures 1, 2 and 3) are led through a circular array of circumferentially distributed discharge holes 144 ( Figures 1, 2, 8 and 9) extending longitudinally through the wrapping nose 102.
  • the wires pass over adjustable guides 146 ( Figures 1, 2, 8 and 10) which serve to apply controllable tension to the wires as they pass through the wrapping nose 102.
  • the tensioning guides 146 are adjustable (for controlled variation of wire tension) by means of adjustment screws 148 ( Figures 1, 2 and 8) which are locked in place following adjustment by means of lock-nuts 150.
  • the wrapping nose 102 is normally permanently attached to the sleeve 138 of the first wire-supplying section 104 by means of screws 152 ( Figures 1, 2, 5 and 8). Co-rotation of the wrapping nose 102 and the first section 104 during wire-wrapping operation of the machine 100 is ensured by means of drive pins 154 ( Figures 1 and 2) extending axially rearwards (rightwards as viewed in Figures 1 and 2) from the sleeve 138 and into corresponding drive sockets 156 ( Figures 1, 2, 3 and 5) in the forward end of the outer part 136 of the first wire-supplying section 104.
  • Similar drive pins 158 ( Figures 1, 2 and 4) axially projecting from the rear (rightwards) end of the first section 104 rotationally couple the first wire- supplying section 104 to the second wire-supplying section 106 by way of complementary drive sockets 159 (Fig. 6) in the forward (leftwards) end of the second section 106 for conjoint rotation of both sections during wire-wrapping operation of the machine 100 while allowing the section 106 to be axially separated from the section 104 (as depicted in Figure 1) when it is desired to replace depleted reels 122 on the first section 104 with wire-filled reels.
  • the rotatable parts of the assembly are rotated by a suitable drive gear 164 ( Figure 1) capable of starting, stopping, and providing adequate torque at a suitable speed, all in a fully controllable manner.
  • suitable means of known form for guiding, supporting, and longitudinally drawing a flexible pipe 200 through the wrapping machine 100 while preventing the pipe 200 from rotating can comprise an array of motor-driven pipe-pulling caterpillar tracks (not shown) clamped against a length of the pipe 200 downstream (left) of the machine 100, together with suitably located pipe-supporting rollers (not shown)).
  • Operation of the wrapping machine 100 to wrap the pipe 200 with a layer of helically wound armouring wires 134 is illustrated in Figure 11 (wherein only part of the machine 100 is shown) .
  • a preferred lay angle during normal operation is 54*-°.
  • the pipe 200 is longitudinally moving from right to left (but without rotation) through the machine 100 whose rotatable parts are rotating clockwise as viewed looking onto its forward (leftmost) end ( ie as viewed from the left in Figure 11)/ the machine 100 being longitudinally stationary.
  • the rotatable parts of the machine 100 are rotating in Figure 11 such that the upper half of the rotatable assembly is advancing out of the plane of Figure 11 while the lower half of the rotatable assembly is retreating into the plane of Figure 11).
  • the drive means 164 is preferably selectively reversible such that a flexible pipe could be wrapped with armouring wires in helices of a hand opposite of that shown in Figure 11 ( ie anti-clockwise instead of clockwise) .
  • the capability of reversible rotation is particularly useful if the same wrapping machine is to be utilised for wrapping a pipe (one layer at a time) with two or more layers of armouring wire wherein successive layers have wires that cross those of the immediately underlying layer.
  • a fundamental advantage of the machine 100 lies in its ability to helically wrap a pipe (or any other elongate workpiece) with wire (or any other filamentary wrapping material) supplied from reels or bobbins that are substantially coaxial with the pipe or the workpiece being wrapped, rather than being in orbit around the pipe as with prior-art wrapping machines .
  • the ability of the machine 100 to have a variable number of wire- supplying sections coupled together provides the advantage of flexibility in the number of wires selected to be wrapped simultaneously.
  • the longitudinal division of the machine 100 into a number of sections also facilitates the replacement of any selected wire reel since only a small number of reels at most ( four at most in the preferred embodiment described with reference to Figures 1 - 11) need be removed from any separated section to reach a given reel. (If the latter advantage can be foregone, especially if the number of wires is small, the wrapping machine need not be longitudinally sub-divided into a plurality of sections).
  • the wrapping machine of the present invention could be employed for wrapping non-armouring sheathing wires, shielding materials, or any other selected filamentary material capable of being wrapped onto a pipe from pre- wound reels.
  • the present invention can be utilised for wrapping hoses, cables, umbilicals (assemblies of multiple hoses and/or cables), rigid pipes, and other forms of longitudinally extended articles.
  • the number of reels per section, and the number of sections per machine, can be different from the five reels per section/two-section machine schematically illustrated in Figs. 1-11.

Abstract

L'invention concerne une machine enrouleuse de fil (100) qui permet d'enrouler de manière hélicoïdale un fil d'armure (134) ou autre matériau filamentaire autour de tuyaux flexibles (200) ou autres pièces à travailler de forme allongée. Des dévidoirs de fil (122) sont montés rotatifs sur la machine (100), selon le même axe que l'axe longitudinal (124) de la machine (100). Pour faciliter l'accès aux dévidoirs individuels (122) et pour donner une certaine souplesse à la configuration de la machine (100), celle-ci (100) est subdivisée longitudinalement en une pluralité de parties à dévidoirs de fil montés rotatifs (104, 106), lesquels peuvent être séparés axialement de manière à permettre le remplacement des bobines vides par des bobines préenroulées, puis réinstallés pour l'opération d'enroulement du fil. Par rapport aux machines existantes sur lesquelles les dévidoirs de fil sont en orbite autour de la pièce à travailler, la machine considérée est plus compacte et fonctionne à des vitesses supérieures.
