Definitions

  • This invention relates to a method of taping a harness comprising a bundle of cables, and a machine therefor.
  • a known taping device 10 is shown in Figures la and lb.
  • the device comprises a static support 1 with a bearing 6, within which a large wheel 2 is rotatably mounted, further comprising a tape roll 3 mounted on an axis 7 pivotally to the wheel 2 and comprising a tape 5.
  • the tape is spiralled around a section 4 of harness comprising a plurality of wires (not shown) .
  • the wheel 2 and support 1 have a U-shaped slot 8 to enable the harness section 4 to be positioned in alignment with the axis of the wheel.
  • the wheel can then be rotated in the rotation direction R whilst the harness is fed in the axial direction such that the tape unrolls from the roll 3 and winds in a spiral around the harness.
  • the section of harness to be taped is supported typically by two grippers at either end, for example, positioned proximate nodes of the harness, the grippers being pulled apart to straighten the cable.
  • the harness is manually fitted to the grippers, but the axial feeding and rotation of the wheel may be motor driven.
  • the above method only enables a single section of harness between nodes to be taped, without intervention of an operator. An operator has to remove and reset the tape in the grippers when another section of the cable between different nodes, must be taped. This is a labour intensive and therefore costly procedure.
  • the taping of sections of a harness that is complex with many nodes and different lengths of harness between nodes can be taped in a fully automated manner, yet in a reliable and cost effective manner.
  • the method enables incorporation of a taping device in a known linear harness making machine without extensive redesign. This is particularly advantageous as the known linear harness making machine carrying out the invention described in FR 2 707 828 is able to produce complex harnesses, and the ability to integrate taping of such harnesses in a machine adapted to carry out such a method provides a particularly simple and flexible harness making procedure that is fully automated.
  • Figure 2 is a schematic side view of part of the harness making machine according to this invention.
  • Figures 3a to 3j are views similar to that of Figure 2 illustrating the various steps in the automated taping of a harness.
  • a taping section 12 of a harness making machine comprising a taping device 10 similar to that already described above and illustrated in Figures la and lb, and a harness transport system 16 having a first conveyor 18, a second conveyor 20, and a bridging conveyor 22.
  • the conveyors 18 and 20 are of a similar construction and comprise cogs 24,26 at either end that support a flexible belt 28 that has teeth 30 for engaging in teeth 32 of pallets 34 that support connectors, or ends of branches of a harness 36.
  • the pallet members 34 may also be grippers for holding the harness at the nodes 37,38,39. Between the nodes 37,38 and 38,39 are harness sections 4 and 4' to be taped.
  • the bridging conveyor member 22 further comprises a displacement means 42 comprising a piston rod 43 actuated by a piston 44, wherein the bridging cog 40 is supported on the piston rod 43.
  • the piston 44 can be actuated to displace the cog 40 below the conveyors 18,20 thus providing a gap between the conveyors.
  • the taping device 10 is positioned in vertical alignment with the bridging cog 40 and has a sufficiently small thickness to fit in the gap between the first and second conveyors 18,20 respectively. All movements of the various parts such as conveyors, piston and taping device can be co-ordinated by computer control means. The taping device 10 can also be displaced by piston means or any other known mechanical means.
  • the harness 36 is on the first conveyor 18, the taping device is in a rest position at a distance from the conveyors, and the bridging cog 40 is positioned in the gap between the first 18 and second 20 conveyors.
  • a first node 37 of the harness 36 can thus traverse from the first conveyor 18 to the second conveyor 20 as shown in Figure 3b.
  • the bridging cog 40 is retracted by the piston 44, and subsequently the taping device 10 is displaced into the gap between the conveyors 18,20 as shown in Figure 3c.
  • the first section 4 of harness to be taped is thus received in the slot 8 of the taping device (as shown in Figures la and lb) , the taping device 10 being positioned such that its axis of rotation coincides with that of the harness.
  • the taping device wheel 2 is rotated, and simultaneously the first and second conveyors 18,20 transport the harness in the axial direction until the second node 38 arrives at the taping device 10 as shown in Figure 3d.
  • the taping device 10 is then retracted, and subsequently the bridging cog 40 is inserted into the gap between the first and second conveyors as shown in Figure 3e.
  • the second node 34 can then be transported over the bridging cog 40 to the second conveyor 20 as shown in Figure 3f.
  • the bridging cog 40 is then retracted and the taping device 10 positioned over the second section 4' of harness to be taped.
  • Figures 3h and 3i correspond to the steps shown in Figures 3d and 3e respectively.
  • Figure 3j shows the completed harness being transported away on the second conveyor.

Abstract

Une section d'enrubannage (14) d'une machine enrubanneuse comprend un dispositif d'enrubannage (10), deux bandes transporteuses (18, 20) et une bande transporteuse de liaison (40) placée entre elles. La bande transporteuse de liaison (40) permet le passage des palettes (34) qui transportent les noeuds d'attache d'un harnais de câbles (36) de la première bande transporteuse (18) vers la seconde bande transporteuse (20). Lorsqu'un noeud d'attache est passé de la première à la seconde bande transporteuse, la bande transporteuse de liaison (40) est retirée par mouvement vertical par la tige de piston (43), pour permettre au dispositif d'enrubannage (10) d'être placé entre les deux bandes transporteuses. Le harnais de câbles (4) est alors reçu dans une fente (8) du dispositif d'enrubannage, lequel procède à l'opération d'enrubannage du harnais de câbles, pendant que celui-ci est déplacé axiallement par les bandes transporteuses jusqu'à ce que la seconde palette (38) atteigne le dispositif d'enrubannage (10). Le dispositif d'enrubannage est alors retiré, la bande transporteuse de liaison (14) est réinsérée et l'opération continue comme décrite ci-dessus pour l'enrubannage de la seconde section (4') du harnais de câbles entre les noeuds d'attache (38, 39). On obtient ainsi une procédure automatisée simple pour l'enrubannage de harnais de câbles.
