  • the device advantageously thus comprises means for unwinding sections of wire of predetermined lengths as well as control means which control the unwinding of the wire and which stop the wire at predetermined intermediate points corresponding to branches.
  • said control means are advantageously included in the form of software in the computer (42).
  • Another advantageous solution consists in placing a programmable controller or a secondary computer (42 ′) on the loading unit, and connecting it by at least one link to the main computer (42). This automaton specifically controls said unit and commands the execution of global actions from which it receives the definition by means of said link.
  • Figure 14 shows end clamps, like (3 ⁇ j ′) and (3 ⁇ m ′), holding ends, like (26′C) and (26′A). It also shows branch clamps, like (3 ⁇ k ′) and (3 ⁇ l ′), now intermediate points associated with branches, like (26′A ′). This figure shows that one grips and maintains the section of wire in bypass clamps at other intermediate points of the ends which are associated with bundle leads.
  • these clamps are transferred by the conveyor (1 ′) to the grouping unit (43) which makes it possible to group together in a same branch clamp several of said intermediate points which are associated with the same branch.
  • the conveyor (1 ′) has transferred in the field of action of the transfer unit (43), the grippers (3 ⁇ k) and (3 ⁇ j), as well than the nine empty clamps, (3 ⁇ a) to (3 ⁇ i).
  • the transfer unit is advantageously placed astride two conveyors, the motors of which are independent.
  • the toothed belt conveyor (1 ′) ends between the clamps (3 ⁇ j) and (3 ⁇ i). He drives the pliers to the pliers (3 ⁇ j). It is followed by the conveyor (1 ′) which drives the grippers from the gripper (3 ⁇ i).
  • the transfer unit has gripping means capable of simultaneously gripping two intermediate points and the field of action of this transfer unit (43) includes at least two grippers on the upstream conveyor (1 ′) for simultaneously transferring the two intermediate points of a wire associated with the same branch on two branch clamps carried by the downstream conveyor (1 ′).
  • FIG. 14 shows an exemplary embodiment of this transfer unit (43).
  • a manipulator is provided with two grippers, (44) and (44 ′), of the same type as the gripper (38). This manipulator is also provided with means making it possible to move them from one point to another of said conveyor.
  • a first part of these displacement means consists of two jacks (45), (45 ′) similar to the jack (41), which allow the gripping means (44), (44 ′) to descend independently to the clamps (3 ⁇ a) to (3 ⁇ j).
  • the second part of these means is of the screw-nut type.
  • the motor (46) rotates the endless screw (47) which collaborates with the nut fixed on the mobile assembly (48).
  • This nut drives this assembly (48) in translation, guided by the slides (49), along the conveyor so that the gripping members move vertically from the grippers (3 ⁇ a) to (3 ⁇ j).
  • this first manipulator (44) can grasp the end held by the clamp (3 ⁇ j) which is then opened by the opening means associated with it, release said end of said clamp which once empty is closed , move and engage this end in another predetermined clamp (3 ⁇ a) to (3 ⁇ i).
  • the clamp (3 ⁇ j) is then ejected towards the return conveyor according to an embodiment taught in patent FR 90 13137 (RICARD Claude).
  • the ejection means (19) of the empty grippers from the conveyor (1 ′) to the return conveyor are located at the grippers (3 ⁇ k) and (3 ⁇ j) as shown in FIG. 14.
  • gripping members include pliers (38 ′) and (38 ⁇ ) produced according to the example of FIGS. 15 and 16.
  • the pliers (38 ′) force the opening of the beaks (50) of the pliers (3 ⁇ j).
  • the spouts are separated by the action of this wire which acts as a wedge on the part (50a) of said spouts.
  • the "V" shape facilitates the opening of these spouts pivoting around the axes (52b) and kept closed by the springs (51).
  • the gripping pliers advantageously comprises a pushing finger (53) which can engage between the beaks of the pliers and which supports the wire during the engagement of the latter in a clamp and which temporarily holds it during the withdrawal phase.
  • the wire is held by the gripper (38 ′), produced according to the example of Figures 15 to 19.
  • this wire is held, inter alia, by the finger (53) which supports the wire which repels the piston (52).
  • the lower part of the finger (53) is at the same level as the detail of internal shape (50b) of the spouts.
  • said finger comprises at its lower part in contact with the wire a shape detail (69) for retaining the wire and whose profile has a "V" shape or a concave shape.
  • the clamp is produced by a tangle of spouts or if the clamp has details of shape obstructing the use of a finger as shown, said finger will advantageously be cut to slip between said spouts or avoid said details of shape.
  • the wire or the various wires present in the clamp are held, temporarily and in particular when the beaks are forced to open by the wire put in place, by compression between the piston (52) pushed towards the finger by the spring. (54) and the finger (53). These wires are also compressed and held by shearing between the edges of the piston (52) and the edges of the fingers (50) closed by the springs (51).
  • the cavity formed by the profile (50b) of the spouts and the profile (52a) of the piston adapts to the volume of the wires which it keeps compressed.
  • it is the wire itself which forces the beaks to open, the beaks only open to let it pass and the already existing wires cannot escape.
  • the computer moves the mobile assembly (48) to bring the member (44) vertically to the clamp (3 ⁇ a). He commits said end in this empty clamp of said conveyor by lowering the gripping means in the low position as described above.
  • the wires of the branches of a branch are arranged and kept separately, branch by branch, in several branch clamps (3 ⁇ ) arranged contiguously.
  • FIG. 14 also represents a particular embodiment of the invention in which the branches are attached in the vicinity of the branch clamps by the link laying unit (55).
  • this link laying unit is located downstream from the transfer unit (43). It consists of a jack (56), controlled by the computer (42), which lowers the known type of binding pliers (10) so that its beaks (10a) grip all the wires of a branch included in the bypass clamp presented to it by the conveyor (1 ⁇ ). The computer then commands the binding pliers to attach the wires of the said branch together, to open the beaks (10a) and to bring the binding pliers back above the said bypass pliers.
  • the gripper conveyor (2) transports a gripper (3) of which only the foot is represented by means of the belt (60). This foot has a sole (57) whose width (57a) is slightly less than the width (58) of the profile to allow good guiding of the base in the profile.
  • the length (57b) is slightly less than the length of the notch (58) in order to allow the transfer of the clamp along the axis (X′X). This transfer is carried out by sliding, pulling or pushing the clamp.
  • the base teeth then slide on the teeth of the belts (60) and (61), and on the teeth of the racks (62) and (63) cut in the profile.
  • the teeth of the belts, in the position of gripper transfer, and the teeth of said racks are aligned.
  • This device (23a) is produced by means of a hollow elastic rubber piece. This part can be pressurized and inflated like a balloon by injecting compressed air inside through the hollow axis (23b). This part can also be left to stand by venting to the atmosphere. This device (23a) freely penetrates, at rest, into the corresponding hole (64) which is provided with the clamp (3a). After being engaged in said hole, it is inflated and expanded by the injection of compressed air, which allows the jack (23) to pull the clamp (3).
  • the carriage (15) is produced according to FIG. 20. It has teeth (68) engaged with teeth of the toothed belt (61) of the conveyor (2 ′).
  • This belt which forms a loop driven by a motor, makes it possible to move the carriage (15) and to bring the axis of the jack which it carries, in correspondence with the axis of the hole (64).
  • the movement of the conveyor (2 ′) also makes it possible to bring the carriage (15d) opposite the stop (4z) so as to align the corner (17) with the light (18).
  • the foot (19) is kept in contact with the toothed belt by means of the friction washer (66) and the elastic piece (67).
  • the outlet of the jack (16) engages said corner (17) in the light (18).
  • the wedge (17) lifts the rod (65) and the foot (19) by compressing the elastic piece or the spring (67).
  • the teeth (66a) of the foot (19) emerge from the complementary teeth (66b) of the toothed belt (20). Once these teeth are released, the carriage (15) allows to move the stop (4) along the conveyor (2 ⁇ ).
