Description

MACHINE FOR PRODUCING CABLE THREADS.

  The present invention relates to an improved machine

  able to produce wired wires in con-

tinu.

  It relates more particularly to perfection

  equipment used to implement the so-called "direct wiring" process known for a long time and

  described in particular in FR-A-1 208 273, 1 175 229, US Pat.

  2,958,177, FR-2,539,765 (corresponding to US-A-4,549

393) and FR-2,565,261.

  As is evident from the documents cited, and in particular from FR-A-2 539 765, for making such cords, machines are used in which each

  working position involves, as is schematically

  Attached to the attached figure, an assembly similar to a spindle double twist spindle (DT set) allowing the union by twisting of two elementary son (1,2) from two power sources (3,4). the food reels (3,4) of the yarns (1,2) are generally arranged in the extension of one another. The thread (1) coming from the spool (3)

  passes through a turntable or the like (5),

  to form a balloon (6) inside which is

  arranged the power source (4) for the wire (2).

  The assembly of the two son (1) and (2) is obtained by twisting at the meeting point (7) using, for example, a twisting head as described in French Patent 1 208 273 or 2 562 261. The formed cable (8) is then conventionally removed, for example by a winding (9) communicating or not additional torsion. Elements (10), (11) are

  provided on the paths of the wires (1), (2) for their

  a precise and constant tension.

  To realize compact machines, particularly with regard to the occupied floor area, and also to have easy-to-use assemblies, in most of the materials proposed to date, the elements constituting the twisting / wiring assembly (together DT) and

  winding means (9) are arranged on a frame

  common port below each other, the food

  (3) wire (1) being made either from a separate creel, or possibly by placing the food coils on the same support frame underneath

  of the DT set. In general, commercial machines

  and have a central support frame of

  on both sides are arranged in a symmetrical

  same working positions.

  This type of material is satisfactory, but

  on the other hand, it leads to a relative height

  important in view of the overlapping of different

  components and, on the other hand, it is not adapted to allow a simple and rational automation of setting up and removal of the coils of wires (coils (3,4) of elementary wires (1,2 ) and

  coil (9) of the wired wire (8) obtained).

  Now it has been found, and this is the subject of the present invention, an improvement to cabling machines of the aforementioned type which makes it possible to overcome these

  disadvantages and in particular to achieve an automatic

  both feeding and feeding reels of yarn and evacuation. coils of wired wires

made.

  In addition, the new machine complies with the

  vention makes it possible to obtain a set whose height is limited and whose access to the various organs (coils

  food and receiving element) is easy.

  In general, the invention therefore relates to an improved machine for continuous son wiring, of the type comprising a predetermined number of working positions arranged on either side of a common support frame, each working position comprising an assembly similar to a spindle double twist spindle for joining by torsion two elementary son from two power sources, and-means for winding the wire obtained, and is characterized in that: - the work position support is designed so that the two faces of the machine are spaced apart from each other, so as to define

  between them an area allowing the passage of two

  one carrier used to ensure the evacuation of the coils-the formed cable, the other to bring to each station of the food coils and this,

  from a stationary power supply provided for in ex-

  tremity of the machine; - The two coils for the elementary son are arranged side by side at the bottom of the support frame. The invention and the advantages it brings will however be better understood thanks to the embodiment given hereinafter by way of indication, but not limiting, and which is illustrated by the appended diagrams in which: FIG. schematically, as indicated above, all the elements involved in the realization of a working position of a cabling machine and the operating process

of such a machine.

  Figure 2 is a side view showing the structure of

  of a machine produced in accordance with the invention, and more particularly two positions arranged

  on both sides of a common support frame.

  FIG. 3 is a front view of a position of

work of such a machine.

  FIGS. 4 and 5 are cross-sectional views

  according to plans AA and BB in Figure 2, it is

  machine made according to the invention.

  In the remainder of the description, for the sake of

  simplification, the same elements will be designated by

the same references.

  Referring to the attached drawings, the cabling machine according to the invention is of the type consisting of a support frame designed so that, if we consider this machine sideways (see Figure 2), two positions of identical workpieces are arranged on either side of a common central part (11). Thus, two faces (respectively referenced G and D in FIGS. 2, 4, 5), identical, to which the operator has access are thus defined on each side of the machine. If we consider this FIG. 2 as well as FIG. 3 which is a side view showing the working position of the right face (D), each working position comprises,

  as described in the preamble of this description, a

  set (DT) similar to a double twist spindle

  deuse and which makes it possible to join by false torsion two

  elementary sons (1,2) from two sources of food

  tion (3,4). The thread (1) coming from the spool (2) passes into a rotary plate (5) constituted by the pot

  a conventional double twist spindle inside

  5 of which is disposed the power source (4) for the wire (2). The assembly of the two son (1,2) is made at the meeting point (7) of known type. Furthermore, conventional tensioning elements are provided in the path of each of the two son (1) and (2) before meeting point (7). Such tensioning elements

  being conventional, they will not be described in detail.

  in this application as a measure of simplification

  tion. In the illustrated embodiment, to

  to provide the torsion to each of the elementary wires (1)

  and (2) double twist conventional pins are used.

  driven by individual motors (12).

  Of course, any other training mode of said

  pins could be considered, for example a training

  a plurality of pins by means of an endless belt controlled by a single common motor. Of

  such double twist brockes being equally well

  in the field of textiles, they will not be

not described in detail.

  According to the invention, to obtain a

  China is particularly compact and can be easily

  In an automated manner, the support frame common to the working positions of the machine is designed in such a way that the two faces G and D of said machine are spaced from one another. To do this, we realize a building such

  illustrated in Figure 2 and which

  base (13) and uprights (14,15). Additional amounts and sleepers are also provided to obtain a rigid carcass. Of course, the form of frame illustrated in Figures 2 and 3 is not given as a limitation, any other equivalent form may

to be considered.

  On the two outer faces of the frame thus

  se, are arranged the different bodies constituting each working position. Figure 3 illustrates such a working position in plan view. In an industrial machine, a plurality of such identical work positions are arranged side by side. The winding elements that each work position comprises are, in this case, constituted by a winding winding system, designated by the reference

  general (16). In Figure 1, only the main or-

  In this winder (16) are shown the bobbin (9) on which the wire is not

  shown, this coil being visible in FIG.

  i5 In the space between the uprights

  (14,15) of the frame, are arranged two transpor-

  stackers (.7,18. and which consist of carpets

  carriers allowing one (18) to ensure the evacuation

  of the coils (9) formed, the other (17)

  putting, as for him, the feeding of the coils (3) of

elementary sons.

  The top view in section AA illustrates how the evacuation of the completed coils is ensured, while Figure 5 (section BB) illustrates the way in which the reel supply is ensured.

food (3).

  Moreover, and this is another element

  of the invention, the two coils (3,4) of the elementary wires (1,2) are arranged side by side, at the

  lower part of the support frame.

  In addition, as is clear from the top views (Figure 4 and 5), if we consider both sides (G) and (D) of the machine, in the two working positions that are back to back the organs are inverted relative to each other. Thanks to such a design of the machine, it is

  possible to obtain a perfectly automated set

  corn. Indeed, when it is desired to remove a full coil (9), the stirrup carrying this coil and which is

  articulated on the frame, makes it possible to

  woring said full spool to bring it onto the conveyor conveyor belt (18). An empty tube is then put in place between the stirrup arms to be brought

  in the winding position as illustrated in FIG.

  Regarding the introduction and removal of food reels (3), firstly, it should be noted that the arrangement in the lower part provides for each coil (3), a spare coil 3 '). The foodstuffs are conveyed by the conveyor belt (171 and when a working spool is

  exhausted, it is then replaced by a new

  full conveyor conveyed by the conveyor belt (17)

  that the spare coil is exhausted, this

  last being then replaced, and so on.

  Such a type of installation makes it possible not only to obtain an easily automatable assembly, but

  It also promotes the process of loading

  positions and evacuation of completed coils

  since all operations can be done

at the end of the machine.

  Such a machine also makes it possible to solve

material storage problems.
