Definitions

  • the present invention relates to a method for inserting wires one by one into a clamp for holding a group of wires. It also relates to a gripper intended for the implementation of this method.
  • the invention relates more particularly to the technical sector of the construction of automatic wiring machines.
  • Patent FR-A-2,619,258 (Claude RICARD) describes in particular a wiring machine in which a connection piece is crimped, at the end of the chain, on the ends of a group of several conductive wires.
  • This machine can use, in one embodiment, clamps for holding this group of wires, which are particularly well suited for this use, and which are described in this document FR-A-2,619,258 with reference to its Figures 4 and 5.
  • This holding clip has two pairs of spouts 14 which are held in the closed position by return springs 15, and it also has a piston 10 which is placed between the two pairs of spouts 14 and which is pushed up by a spring. 13.
  • the upper face of this piston 10 has a flared notch 11.
  • each spout 14 has a ramp (indicated by arrows in FIG. 4) descending towards the center and, immediately below this ramp, a concave notch 11.
  • FIGs 4 and 3 a single wire is shown trapped by the retaining clip but, of course, this clamp is able to hold together a whole group of wires, as shown in Figure 4 of the aforementioned document FR-A-2,619,258.
  • This Figure 4 shows a group of wires in place in the clamp, as well as another wire ready to join the others by simple pushing of this wire from top to bottom, in order to force the opening of the four beaks of the clamp. .
  • Such a manipulator must be equipped with a gripper capable of grasping each wire at two points and, this wire being well tensioned between these two points, then pushing it into the descending ramps of each pair of jaws of the holding clamp , to force these beaks to open and let the wire pass, then to close again on the latter, which then joins the group of wires already trapped in this holding part.
  • the invention relates to a method according to claim 1 and to a gripper for the implementation of this method, according to claim 3.
  • Figures 1 and 2 show a gripper, for the establishment of one or more wires in a holding clamp, in the process of placing a wire in a holding clamp, according to a side view and according to a partial section in elevation.
  • FIGS 3 and 4 already described above, show this holding clamp, of known type, having means for gripping and holding one or more wires, in a side view and in a partial section in elevation.
  • the gripper is fixed by a pin 1 to a manipulator capable of performing the wire transfers, this manipulator being of known type.
  • a yoke 2 supported by the axis 1 carries the two jaws 4 and 5, of each of the two pairs of jaws, one pair being spaced from the other pair, with which this gripper is equipped.
  • These jaws can rotate around axes 3 and they are opened or closed by the action of a jack 6.
  • the jaws hold the wire to be inserted 8 at their ends and the portion of this wire which is between the jaws is kept tight between the two pairs of jaws.
  • This stretched wire portion is further maintained by support means 9 carried by the gripper.
  • These support means are produced by a pushing finger 9 which is fixed on the yoke 2 and which is positioned between the two pairs of jaws of the gripper.
  • the gripping pliers therefore comprises a pushing finger 9 which can engage between the two pairs 14 of beaks of the holding clamp and which supports the wire during the engagement of the latter in a clamp, and which temporarily holds it during the withdrawal phase.
  • this wire When the wire is inserted into a clamp, this wire is held, inter alia, by the finger 9 which supports the stretched portion of the above-mentioned wire and which then pushes the piston 10 against the force of the spring 13.
  • the lower part 12 of the finger 9, which is the active face of said support means, is at the same level as the internal shape detail 11 of the spouts 14 which itself defines the upper limit level of the wires held in the holding clip.
  • the finger 9 comprises, at its lower part in contact with the wire, a shape detail 12 for retaining said portion of wire and whose profile has a "V" shape or a concave shape.
  • the pushing finger 9 is totally or partially made of an elastic material so that this finger remains in contact with the inserted wire 8 longer.
  • this finger is advantageously cut to slip between these beaks and these shape details, and it does not then support the wire tensed 8 only at certain points.
  • the positioning action can be carried out in the same way regardless of the number of wires already in place in the clamp.
  • the cavity formed by the profile 11 of the spouts and the profile 10a of the piston adapts to the volume of the wires which it keeps compressed.
  • the upper limit level of the wires held in place is fixed due to the design of the forceps. But with pliers for which this is not the case, the present invention retains its utility at least for fragile wires.
  • the manipulator stroke is managed according to the variation of said limit level of the wires maintained.

Claims (7)

  1. Verfahren zum Einzeleinbringen von Drähten (8) in eine Halteklemme (14, 10) für eine Gruppe von Drähten (8, 16), dadurch gekennzeichnet, daß während des Einbringens
    - ein Abschnitt des einzubringenden Drahtes zwischen zwei Klemmbackenpaaren (4, 5) einer anderen Klemme, Greifklemme genannt, straff gespannt wird und
    - dieser Drahtabschnitt, der zwischen den beiden Klemmbackenpaaren (4, 5) eingespannt ist, von einer Halteanordnung (9) unterstützt wird, welche von der Greifklemme getragen wird, um so während des Einbringens dieses Drahtabschnittes in die Halteklemme (14, 10) die Wirkung des Gegendrucks zu kompensieren, die ansonsten dazu neigen würde, diesen Drahtabschnitt zu verformen oder sogar zu beschädigen.
  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß während des Einsetzens eines Drahtes (8) in eine Halteklemme (14, 10) die Greifklemme (1 bis 7) dieser Halteklemme (14, 10) angenähert wird, dergestalt, daß die wirksame Fläche (12) der Halteanordnung (9) die obere Grenzhöhe der unterstützten Drähte (6, 8) erreicht.
  3. Greifklemme zur Durchführung des Verfahrens nach Anspruch 1 oder Anspruch 2, wobei diese Klemme zwei Klemmbackenpaare (4, 5) aufweist, die in der Lage sind, einen in die Halteklemme (14, 10) einzubringenden Draht zu ergreifen und straff zu spannen, dadurch gekennzeichnet, daß sie außerdem einen Druckfinger (9) aufweist, der zwischen diesen beiden Klemmbackenpaaren (4, 5) angeordnet ist und den gespannten Draht (8) während dessen Einbringens in die Halteklemme (14, 15) unterstützt und der außerdem vorübergehend diesen Draht (8) an Ort und Stelle hält während der Rückzugsphase der Greifklemme.
  4. Klemme nach Anspruch 3, dadurch gekennzeichnet, daß der Finger (9) an seinem unteren den Draht (8) berührenden Abschnitt eine Form (12) aufweist, dessen Profil V-förmig oder konkavförmig ist.
