FR2519181A1 - Rotating cage bundled-cable winding machine - uses synchronised winders which firstly wind small groups of cables which are then wound together to form larger cable - Google Patents

Abstract

The rotating cage cable winding machine comprises a rotating plate having multiple holes to allow passage of individual conductors which then pass through rotating guides which wind the individual cables together to form bundles. The cable bundles are then tied. A geared mechanical coupling or a synchronised electric motor drive may be used to drive the plate and guides. A continuity detector is mounted on each rotary guide and stops the machine if a breakage occurs. The machine is able to wind individual cables into small groups prior to the small groups of cable being wound together to form a large composite cable.

Description

Rotating cage machine for assembling insulated conductors into a bundle
The present invention relates to a rotary cage machine for assembling insulated conductors into a bundle, comprising an upstream turntable pierced with holes for passage of the conductors and a common orifice downstream from the assembly of all the conductors to form the bundle .

 The. known machines only allow the assembly of individual conductors into a stranded bundle. If one wanted to assemble these conductors in subunits of two Qu four conductors, then these subunits in a final bundle, or even in intermediate units, then these in a final bundle, it was necessary to provide a machine for assembly to obtain each sub-unit, followed by a garland by winding around the sub-unit of a textile thread, then either a final machine assembling the sub-units to form the bundle, or machines assembling the intermediate sub-units, and a final machine forming the beam. Such assemblies were bulky and the speed of fabrication of the final bundle was low.

 The object of the present invention is to provide a more compact assembly machine with a higher manufacturing speed, but the monitoring of which is easy.

 The assembly machine according to the invention is characterized in that it comprises between the upstream plate and the common downstream orifice of the rotary members for grouping the conductors into at least one series of twisted elementary units and of the ligating members of each of these elementary units.

 It also preferably meets at least one of the following characteristics - The grouping and ligating members are supported by mechanical transmission with distortion of the rotational movement of the plate.

- The grouping and ligating bodies are driven by motors synchronized with the speed of rotation of the plate.

- A breakage detector is associated with each binding device
link ordering his arrest following a broken ligatu wire
rage.

-The breakage detector of the link is constituted by a weighted stirrup fixed on a rotating nose with the ligating member, and a bristle brush made of conductive metal, at a distance such from the ligating member that the stirrup comes in contact with the brush under the effect of
centrifugal force if the link is broken.

It is described below, by way of example and with reference to
Figures of the accompanying drawing, a rotary cage assembler of telephone conductors provided with a device for garlanding these conductors.

 Figure 1 shows the garland plate in elevation seen from the front.

 Figure 2 shows the garland tray, in elevation seen from the rear.

 FIG. 3 represents the device for transmitting the detorsion movement to the chainring plate by the main cage.

Figure 4 shows in perspective a detector device of
breaks the link around the conductors.

 Figure 5 shows in side elevation a garland plate similar to that of Figure 3, but with electric drive.

In FIG. 1, the telephone conductors to be assembled first pass through the orifices of a turntable 1. They go from there to the garland tray 2, also rotating,
disposed in the protective cage 3. A central shaft 2A (Figure 2) rotatably secures the plates 1 and 2. The plate 2 carries the
four bowl holders 4A, 4B, 4C, 4D, fitted with noses 5A, 5B, 5C, 5D
for guiding the sub-units formed. On these noses are arranged the garland wire coils 10A, 10B, 10C, 10D. In the case of
bowl holder 4A, conductors 6, 7, 8, 9 coming from the plate
turning 1 are twisted as they pass through the nose 5A by the
rotation of it on the plate 2.Simultaneously, a wire link of
colored cotton supplied from the bobbin 10A, enters the nose 5A and wraps around the quarter of conductors, the color of the link allowing the location thereof. This operation will be described later in more detail with reference to FIG. 4. It therefore leaves the noses of the bobbins of the ligated and marked quarters 11A, 11B, 11C, 11D. We also see at the bottom of the figure a brush 27 of conductive metal bristles, intended to cause the device to stop in the event of breakage of the link, the operation of which will also be described with reference to FIG. -4.

 FIGS. 2 and 3 show how the transmission of the untwisting rotational movement takes place.

 The cradle 20, to which the detour rotation movement is imparted by a set of pinions (not shown), drives the axis 21, on which the toothed pulley 22 is wedged. The toothed belt 23 transmits the rotary movement to the connecting shaft 13. The latter drives at its other end the pinion 14, engaged with the pinion 15, wedged on the shaft 15A passing through the garland plate 2. The pinion 25 carried by the shaft 15A is engaged with the pinion 26, driving the bowl holder plate 4C. Furthermore, the shaft 15A collects the other bowl-holder plates 4A, 4B, 4D by means of the pulley 15B wedged on it, the toothed belt 16 and the toothed pulleys 17, 18, 19.

 FIG. 4 shows on a larger scale the winding of the link around the conductors assembled in the guide nose 5C and the breakage detector of this link. The link 30 supplied from the coil 10C is guided by the references such as 31 towards the orifice 31A drilled in the nose 5C. It wraps around the conductors, due to their rotational movement, to form the fourth 32.

 The link breakage detector comprises a stirrup ballasted at its end by the cylindrical part 34. The latter comes to bear against the link 30, under the effect of centrifugal force. Furthermore, a brush 27 with bristles of a good conductive metal is disposed under the nose 5C.

 If the link 30 breaks, it no longer holds the cylindrical part 34 of the stirrup, and the latter rubs against the brush 27, thereby creating a short circuit, which triggers a circuit breaker (not shown) , which stops the machine.

 Figure 5 shows with partial cutaway a garland tray with electric drive. The bowl-holder supports 4A, 4C, 4D are driven by motors such as 40, with tachometric dynamo 41, ensuring its synchronization with the speed of rotation of the assembly cage.

 The motors are supplied via a collector 42 fixed on the periphery of the garland plate, on which brushes such as 43 rub, supplied by conductors 44.

 The functioning of the bowl-holder supports and their nezo as well as the breakage detector is for the rest the same as that described with reference to FIG. 4.

 Although the assembly machines which have just been described with reference respectively to FIGS. 1 to 4 and 5 appear to be the most advantageous embodiments of the invention, it will be understood that various modifications can be made to them without departing from the scope of the invention, some of their organs being able to be replaced by others which would play the same technical role. In particular, the pitch or the direction of garland, in the case of a mechanical drive, can be changed by changing the transmission pinions or adding additional pinions, for reversing the direction of rotation.
