Description

PROCEDE ET DISPOSITIF DE CONFORMATION D'UN FAISCEAU RAMIFIE METHOD AND DEVICE FOR CONFORMING A BRANCHED BEAM
La présente invention est relative à un procédé et un dispositif permettant de conformer, c'est-à-dire de mettre en forme notamment par ligaturage et/ou enrubannage, des faisceaux de fils électriques ou fibres, tubes ou câbles.The present invention relates to a method and a device for shaping, that is to say shaping, in particular by tying and / or wrapping, bundles of electric wires or fibers, tubes or cables.
Le domaine technique de l'invention est celui de la fabrication de faisceaux électriques.The technical field of the invention is that of the manufacture of electrical harnesses.
Les faisceaux électriques sont constitués à partir de tronçons de fils électriquement conducteurs dont les extrémités sont "traitées", c'est-à-dire généralement dénudées, munies de cosses serties et/ou enfichées dans des alvéoles de connecteurs électriques.The electrical harnesses consist of sections of electrically conductive wires whose ends are "treated", that is to say generally stripped, provided with crimped lugs and / or plugged into cells of electrical connectors.
La préparation des constituants des faisceaux électriques peut être automatisée et de tels dispositifs sont notamment décrits dans la demande de brevet W093/00730 (l'Entreprise Industrielle) qui décrit des dispositifs d'insertion et de manipulation de tronçons de fils électriques permettant de constituer des faisceaux de fils électriques ; d'autres dispositifs de fabrication de faisceaux électriques sont également décrits par exemple dans le brevet GB2087760 (YASAKI) qui décrit des dispositifs d'insertion et de préparation d'extrémités de tronçons de fils destinés à constituer des faisceaux ; dans ce document figure 8, est notamment représenté un faisceau de fils électriques ayant une structure ramifiée comportant plusieurs branches.The preparation of the components of the electrical harnesses can be automated and such devices are described in particular in patent application WO93 / 00730 (the Industrial Company) which describes devices for inserting and manipulating sections of electrical wires making it possible to constitute bundles of electric wires; other devices for manufacturing electrical bundles are also described, for example, in patent GB2087760 (YASAKI) which describes devices for inserting and preparing the ends of sections of wires intended to constitute bundles; in this document FIG. 8, is notably represented a bundle of electric wires having a branched structure comprising several branches.
Dans la présente demande, on utilisera les termes de branches terminales pour désigner des parties d'un faisceau électrique constituées par des parties de tronçons de fils dont des extrémités sont regroupées entre elles pour constituer une extrémité (dite extrémité libre) de la branche terminale, l'autre extrémité de la branche terminale étant désignée sous 1'appellation de noeud et constituant une extrémité d'une autre branche ; dans la présente demande on désigne par branche centrale une branche limitée par deux noeuds et ne comportant pas d'extrémité de tronçons de fils, constitués uniquement par des portions de tronçons de fils et reliant entre elles au moins deux branches (terminales ou non). La figure 8 du brevet YASAKI cité ci-dessus illustre une manière traditionnelle de conformation manuelle de faisceaux électriques dans laquelle on dispose les tronçons de fils destinés à constituer le faisceau sur une table ou plan de travail, qui peut être horizontaleIn the present application, the terms of terminal branches will be used to designate parts of an electric bundle constituted by parts of sections of wires, the ends of which are grouped together to form one end (called the free end) of the terminal branch, the other end of the terminal branch being designated as a node and constituting one end of another branch; in the present application, the term central branch designates a branch bounded by two nodes and having no end of sections of wires, constituted only by portions of sections of wires and connecting together at least two branches (terminal or not).

Les figures 3 et 4 représente un autre faisceau très simple qui comporte, en supplément par rapport au faisceau représenté aux figures 1 et 2, un troisième tronçon de fil 15 muni de deux extrémités 16 et 17 qui sont respectivement regroupés avec l'eextrémité 3 dudit tronçon de fil 1 et l'extrémité 6 dudit tronçon de fil 4. On obtient ainsi un faisceau à trois branches 11, 12, 13 chacune desdites branches étant constituée par l'assemblage (grâce à des liens 7, 8) de parties desdits tronçons de fils 1, 4, 15.Said link 8 which can be qualified as an intermediate link will be located near the node by reference to FIG. 2. FIGS. 3 and 4 represent another very simple beam which comprises, in addition to the beam shown in FIGS. 1 and 2, a third section of wire 15 provided with two ends 16 and 17 which are respectively grouped with the end 3 of said section of wire 1 and the end 6 of said section of wire 4. A bundle with three branches 11, 12, 13 is thus obtained, each of said branches being constituted by the assembly (by means of links 7, 8) of parts of said sections of wires 1, 4, 15.
On voit à la figure --J que lesdites branches 11, 12, 13 se rejoignent en un point théorique 9 appelé noeud, ce noeud étant matérialisé généralement, comme représenté à la figure 3. par la jonction mécanique des trois branches qui est réalisée par la mise en place de liens 8 à proximité du point de rencontre ou noeud des trois branches. Comme représenté à la figure un dispositif conforme à l'invention comporte deux convoyeurs principaux 18 et 26 qui sont de préférence du type convoyeur à bande sans fin, de préférence ladite bande sans fin étant constituée par une courroie crantée sur sa face extérieure au moins, laquelle bande est tendue entre des rouleaux 20 respectivement 28 et entrainée en déplacement par rotation d'un au moins desdits rouleaux, lequel rouleau est entrainé respectivement par un moteur 21, 29 et une courroie d'entraînement 22, 30« lesquels moteurs 21, 29 sont de préférence des moteurs synchrones pas à pas permettant de provoquer un mouvement précis d'avance ou de recul de ladite bande sans fin sur laquelle sont disposés des supports 23, 24, 25 de groupes d'extrémités;We see in Figure --J that said branches 11, 12, 13 meet at a theoretical point 9 called node, this node being generally materialized, as shown in Figure 3. by the mechanical junction of the three branches which is achieved by the establishment of links 8 near the meeting point or node of the three branches. As shown in the figure, a device according to the invention comprises two main conveyors 18 and 26 which are preferably of the endless belt conveyor type, preferably said endless belt being constituted by a notched belt on at least its outer face, which strip is stretched between rollers 20 respectively 28 and driven in rotation by rotation of at least one of said rollers, which roller is driven respectively by a motor 21, 29 and a drive belt 22, 30 "which motors 21, 29 are preferably synchronous stepping motors making it possible to cause a precise movement in advance or backward of said endless belt on which supports 23, 24, 25 of end groups are arranged;
Lesdits convoyeurs 18 et 26 sont sensiblement placés dans l'alignement l'un de l'autre c'est à dire s'étendent selon un axe longitudinal commun XXI de préférence horizontal. Un poste ou une machine de ligaturage, de préférence fixe, est placé à proximité dudit convoyeur 26 applé convoyeur aval, par référence audit convoyeur 18 appelé convoyeur amont, sur lequel sont disposés lesdits supports 23, 24, 25 tenant les extrémités de tronçons de fils ou groupes d'extrémités de tronçons de fils formant lesdites extrémités libres du faisceau à conformer ; lesdits supports 23, 24, 25 tenant lesdites extrémités libres (ou groupes d'extrémités) peuvent soit être placés manuellement sur l'un desdits convoyeurs soit être transférés automatiquement par un dispositif tel que ceux décrits dans la demande 09300730 sus-citée. Les pinces de maintien d'extrémités ou de groupes d'extrémités peuvent par exemple être du type de celles décrites dans la demande de brevet FR87/11392 (Automatismes et Robotique appliqués ARA) , et dans le cas où les extrémités seraient équipées de connecteurs, les supports de groupes d'extrémités, c'est à dire d'extrémités libres desdites branches terminales, peuvent être constitués par des supports décrits dans la demande de brevet FR2 671 236 (L'Entreprise Industrielle) ; ces supports pouvant être constitués par des pinces ou des supports de connecteur sont dans la présente demande généralement désignés sous le terme de suppport de groupes d'extrémités ou sous le terme de support d'extrémité libre de branche terminale.Said conveyors 18 and 26 are substantially placed in alignment with one another, that is to say extend along a common longitudinal axis XXI, preferably horizontal. A station or tying machine, preferably fixed, is placed near said conveyor 26 applied downstream conveyor, by reference to said conveyor 18 called upstream conveyor, on which are arranged said supports 23, 24, 25 holding the ends of sections of son or groups of ends of sections of wires forming said free ends of the bundle to be conformed; said supports 23, 24, 25 holding said free ends (or groups of ends) can either be placed manually on one of said conveyors or be transferred automatically by a device such as those described in the aforementioned application 09300730. The clamps for holding ends or groups of ends can for example be of the type described in patent application FR87 / 11392 (Automatisms and Robotics applied ARA), and in if the ends are fitted with connectors, the end group supports, that is to say the free ends of said end branches, can be constituted by supports described in patent application FR2 671 236 (The Company Industrial); these supports which may be constituted by clips or connector supports are in the present application generally designated by the term of support for groups of ends or by the term of support of free end of terminal branch.
Par référence aux figures 5 et 6, lesdits tronçons de fils 1 et 4 destinés à constituer le faisceau représenté aux figures 1 et 2 qui sont situés sur ledit convoyeur amont 18, peuvent voir leurs extrémités permutées et transférées en partie au moins sur le convoyeur 26 selon les étapes décrites aux figures 15 à 20; Par référence à ces figures 15 à 20, on voit que le dispositif comporte lesdits convoyeur amont 18 et aval 26 placés dans l'alignement l'un de l'autre et séparé par un dispositif de transfert et de permutation de l'ordre des supports de groupes d'extrémités ou supports d'extrémités libres de branches terminales lesquels moyens de permutation et de transfert peuvent être essentiellement constitués par deux très petits convoyeurs intermédiaires 39 et 40 qui sont susceptibles de se déplacer entre deux positions :With reference to FIGS. 5 and 6, said sections of wires 1 and 4 intended to constitute the bundle shown in FIGS. 1 and 2 which are located on said upstream conveyor 18, can see their ends permuted and transferred in part at least to the conveyor 26 according to the steps described in Figures 15 to 20; With reference to these figures 15 to 20, it can be seen that the device comprises said upstream and downstream conveyor 18 and 26 placed in alignment with one another and separated by a device for transfer and permutation of the order of the supports of groups of ends or supports of free ends of end branches which permutation and transfer means can essentially consist of two very small intermediate conveyors 39 and 40 which are capable of moving between two positions:
- une première position où l'un des convoyeurs intermédiaires, 39 par exemple (par référence à la figure 19) est intercalé entre lesdits convoyeurs 18 et 26, placé dans l'alignement de ceux-ci et permet le transfert du support d'extrémités de branches terminales de l'un à l'autre desdits convoyeurs 18 26 par une rotation des moyens d'entraînement dudit convoyeur intermédiaire,- A first position where one of the intermediate conveyors, 39 for example (with reference to Figure 19) is interposed between said conveyors 18 and 26, placed in alignment with them and allows the transfer of the end support of end branches from one to the other of said conveyors 18 26 by a rotation of the drive means of said intermediate conveyor,
- dans une deuxième position (par référence à la figure 17) où ledit convoyeur intermédiaire 39 s'est déplacé (verticalement par référence à la figure 17) perpendiculairement par rapport à l'axe longitudinal desdits convoyeurs principaux amont et aval 18, 26, ledit convoyeur intermédiaire 39 sert de support temporaire audit support 25 d'extrémité libre de branche terminale et permet au deuxième convoyeur intermédiaire 40 de venir dans une position dans laquelle ledit convoyeur intermédiaire 40 est intercalé entre lesdits convoyeurs 18 et 26 et permet le transfert de l'un vers l'autre desdits convoyeurs 18, 26 d'un autre support 24 de groupe d'extrémités ou d'extrémité libre de branche terminale du faisceau à conformer.- in a second position (with reference to FIG. 17) where said intermediate conveyor 39 has moved (vertically with reference to FIG. 17) perpendicular to the longitudinal axis of said main upstream and downstream conveyors 18, 26, said intermediate conveyor 39 serves as a temporary support for said support 25 for the free end of the terminal branch and allows the second intermediate conveyor 40 to come into a position in which said intermediate conveyor 40 is interposed between said conveyors 18 and 26 and allows the transfer of the one towards the other of said conveyors 18, 26 of another support 24 of group of ends or end free of terminal branch of the bundle to conform.
Par référence à la figure 15, dans cette position, ledit convoyeur 26 porte ledit support de groupes d'extrémités 23 et ledit convoyeur 18 supporte lesdits supports de groupes d'extrémités 24 et 25 ; les deux convoyeurs 18 et 26 sont mis en rotation afin de provoquer un déplacement desdits supports 23, 24 et 25 vers la gauche ; par référence à la figure 16 ledit convoyeur intermédiaire 39 qui est entrainé en synchronisme avec ledit convoyeur 18 par des moyens représentés notamment figure 21, permet le transfert, dudit convoyeur 18 audit convoyeur 26, dudit support 24 et reçoit ensuite ledit support 25.With reference to FIG. 15, in this position, said conveyor 26 carries said support for end groups 23 and said conveyor 18 supports said support for end groups 24 and 25; the two conveyors 18 and 26 are rotated in order to cause a displacement of said supports 23, 24 and 25 to the left; with reference to FIG. 16, said intermediate conveyor 39 which is driven in synchronism with said conveyor 18 by means shown in particular in FIG. 21, allows the transfer, from said conveyor 18 to said conveyor 26, of said support 24 and then receives said support 25.
Par référence à la figure 17 le dispositif de permutation est actionné, qui provoque un déplacement vers le haut dudit convoyeur intermédiaire 39 supportant ledit support 25 et dudit convoyeur 40 qui vient dans une position lui permettant le transfert c'est à dire le retour dudit support 24 du convoyeur 26 (figure 17) au convoyeur 18 (figure 18), grâce à un mouvement vers la droite desdits convoyeurs 18 et 26.With reference to FIG. 17, the permutation device is actuated, which causes an upward displacement of said intermediate conveyor 39 supporting said support 25 and of said conveyor 40 which comes into a position allowing it to be transferred, ie the return of said support 24 from the conveyor 26 (FIG. 17) to the conveyor 18 (FIG. 18), by virtue of a movement to the right of the said conveyors 18 and 26.
Par référence à la figure 19. ledit dispositif de transfert et permutation est ensuite actionné de manière à faire descendre lesdits convoyeurs intermédiaires 39 et 40 jusqu'à ce que ledit convoyeur 39 revienne dans la position intermédiaire entre lesdits convoyeurs 18 et 26, puis lesdits convoyeurs 18 et 26 sont actionnés pour provoquer un déplacement vers la gauche par référence aux figures 19 et 20 ce qui permet de transférer premièrement ledit support 2 dudit convoyeur intermédiaire 39 audit convoyeur aval 26, et ce qui permet de transférer ensuite ledit support 24 dudit convoyeur 18 audit convoyeur 39 puis dudit convoyeur 39 audit convoyeur 26.With reference to FIG. 19. said transfer and permutation device is then actuated so as to lower said intermediate conveyors 39 and 40 until said conveyor 39 returns to the intermediate position between said conveyors 18 and 26, then said conveyors 18 and 26 are actuated to cause a movement to the left with reference to FIGS. 19 and 20 which makes it possible to transfer said support 2 from said intermediate conveyor 39 to said downstream conveyor 26 first, and which then allows said support 24 to be transferred from said conveyor 18 to said conveyor 39 then from said conveyor 39 to said conveyor 26.
Grâce à ces opérations de permutation on peut déplacer les groupes d'extrémités du faisceau représenté figure 5, jusqu'à une position représentée figure 6 dans laquelle une partie au moins d'une branche 11 constituée par une portion des tronçons de fils 1 et 4 est placée en regard d'un poste de ligaturage 31 situé à proximité du convoyeur aval 26, le groupes d'extrémités 34 (regroupant lesdites extrémités 2 et desdits tronçons 1 et 4 respectivement) , qui est tenu par ledit support 23 de groupe d'extrémités, étant situé à gauche dudit poste de ligaturage, c'est-à-dire à gauche de la branche 11 à tendre, sur ledit convoyeur 26, et lesdits supports 25 et 24 desdites extrémités (respectives 6 et 3 desdits tronçons de fils 4 et 1) étant situés sur ledit convoyeur amont 18 à droite de la branche 11 à tendre ; un mouvement respectif desdits convoyeurs 26 et 18 selon les flèches 33 et 32 de sens opposé, permet de placer lesdits de groupes d'extrémités ou de groupes d'extrémités 23, 25, 24 dans des positions dans lesquelles les tronçons de fils 4 et 1 sont sensiblement tendus comme représenté à la figure 6 ce qui permet le ligaturage et/ou 1'enrubannage de la branche 11. Lorsqu'on prévoit notamment un dispositif selon l'invention qui comporte un seul poste 31 de ligaturage susceptible de ligaturer dans une zone relativement restreinte les portions de tronçons de fils qui lui sont présentées, il est nécessaire que la somme des longueurs 38 et 37 respectives des convoyeurs 26 et 18 soit au moins égale au double de la plus grande longueur du faisceau à conformer en l'occurence la longueur du tronçon de fil 1 qui est dans l'exemple traité la plus grande longueur dudit faisceau.Thanks to these permutation operations, it is possible to move the groups of ends of the bundle represented in FIG. 5, to a position represented in FIG. 6 in which at least part of a branch 11 formed by a portion of the sections of wires 1 and 4 is placed next to a ligating station 31 located near the downstream conveyor 26, the end groups 34 (grouping together said ends 2 and said sections 1 and 4 respectively), which is held by said group support 23 ends, being located to the left of said binding station, that is to say to the left of branch 11 to be stretched, on said conveyor 26, and said supports 25 and 24 of said ends (respective 6 and 3 of said sections of wires 4 and 1) being located on said upstream conveyor 18 to the right of branch 11 to be stretched; a respective movement of said conveyors 26 and 18 according to arrows 33 and 32 in opposite directions, makes it possible to place said groups of ends or groups of ends 23, 25, 24 in positions in which the sections of wires 4 and 1 are substantially stretched as shown in Figure 6 which allows the tying and / or wrapping of the branch 11. When providing in particular a device according to the invention which comprises a single station 31 for tying capable of tying in an area relatively restricted the portions of sections of wire which are presented to it, it is necessary that the sum of the respective lengths 38 and 37 of the conveyors 26 and 18 is at least equal to twice the greatest length of the bundle to be conformed in this case the length of the section of wire 1 which is in the example treated the greatest length of said bundle.
A la figure 7 est représenté schématiquement un faisceau électrique un peu plus complexe que ceux des figures 1 à 4, dont les opérations de conformation et enrubannage sont détaillées aux figures 8 à 14.In FIG. 7 is shown schematically a slightly more complex electric harness than those in FIGS. 1 to 4, the shaping and wrapping operations of which are detailed in FIGS. 8 to 14.
Par référence à la figure 7, ledit faisceau comporte 5 groupes d'extrémités A.B.C.D.E et trois noeuds N1.N2.N3 ; ledit faisceau est constitué par cinq branches terminales a, b, c, d, e, reliant respectivement lesdits groupes d'extrémités A,B,C,D,E auxdits noeuds NI,NI,N2,N3,N3, et par deux branches centrales f et g reliant respectivement lesdits noeuds NI et N2, et lesdits noeuds N2 et N3-With reference to FIG. 7, said bundle comprises 5 groups of ends A.B.C.D.E and three nodes N1.N2.N3; said bundle consists of five terminal branches a, b, c, d, e, respectively connecting said groups of ends A, B, C, D, E to said nodes NI, NI, N2, N3, N3, and by two branches central f and g respectively connecting said nodes NI and N2, and said nodes N2 and N3-
Sur les figures 8 à 1-1, on a représenté schématiquement ledit faisceau et on a représenté schématiquement sous ledit faisceau lesdits convoyeurs principaux 18 et 26 dont le sens de déplacement est repéré respectivement par une flèche ; sur ces figures, les groupes d'extrémités (représentés par des cercles) situés à gauche d'un trait pointillé vertical séparant lesdits convoyeurs 18 et 26 sont considérés comme portés par ledit convoyeur 26 ou convoyeur aval, alors que lesdits groupes d'extrémités situés à droite dudit trait pointillé sont censés être déplacés par ledit convoyeur amont 18, vers la droite par rapport aux figures 8 à 14 alors que lesdites premières extrémités sont déplacées vers la gauche par référence aux mêmes figures.In FIGS. 8 to 1-1, said bundle is shown diagrammatically and said main conveyors 18 and 26 have been shown diagrammatically under said bundle, the direction of movement of which is indicated by an arrow respectively; in these figures, the end groups (represented by circles) situated to the left of a vertical dotted line separating said conveyors 18 and 26 are considered to be carried by said conveyor 26 or downstream conveyor, while said end groups located to the right of said dotted line are supposed to be moved by said upstream conveyor 18, to the right with respect to FIGS. 8 to 14 while said first ends are moved to the left by reference to the same figures.
Egalement certaines branches sont représentées sous une forme coudée sans que cette représentation ait une signification particulière mais n'a pour but que de clarifier la lecture de ces figures.Also certain branches are represented in a bent form without this representation having a particular meaning but has for goal only to clarify the reading of these figures.
Par référence à ces figures la position mesurée selon l'axe longitudinal commun auxdits convoyeurs principaux 18 et 26 est représenté en supposant que la longueur de ladite branche terminale (a) est supérieure à la longueur de ladite branche terminale (b) , et que la longueur de ladite branche terminale (c) est inférieure à la somme de la longueur de ladite branche terminale (d) et de la longueur de ladite branche intermédiaire (g) ; la longueur de ladite branche terminale (e) est supposée supérieure à la longueur de ladite branche terminale (d) .With reference to these figures, the position measured along the longitudinal axis common to said main conveyors 18 and 26 is shown assuming that the length of said terminal branch (a) is greater than the length of said terminal branch (b), and that the length of said terminal branch (c) is less than the sum of the length of said terminal branch (d) and the length of said intermediate branch (g); the length of said terminal branch (e) is assumed to be greater than the length of said terminal branch (d).
Par référence à la figure 8, pour tendre la branche terminale (a) et permettre de la ligaturer, dans une zone située à proximité de l'extrémité 26a dudit convoyeur 26, laquelle extrémité 26a est située à proximité dudit convoyeur 18 c'est-à-dire de l'autre convoyeur principal, on déplace ou on transfère le groupe d'extrémités A sur ledit convoyeur 26 et on le déplace vers la gauche jusqu'à une position prédéterminée, et on transfère sur ledit convoyeur 18 les groupes d'extrémités B, C, D, E et on les déplace vers la droite jusqu'à une position déterminée et en respectant un espacement entre lesdites groupes d'extrémités B, C, D, E de manière à ce que l'ensemble des tronçons de fils constituant le faisceau soit sensiblement tendu ; en l'occurrence et à titre d'exemple la distance séparant le groupe d'extrémités A du groupe d'extrémités B, qui est repérée ab, sur la figure 8, sera sensiblement égale à la somme des longueurs des branches terminales (a) et (b) ; de la même façon la distance repérée ac sur la figure 8, séparant lesdits groupes d'extrémités A et C, sera sensiblement égale à la somme des longueurs desditeε branches terminales (c) et (a) et auxquelles s'ajoute la longueur de ladite branche centrale (f). Après que ladite branche (a) soit ligaturée par une machine non représentée ce qui correspond à l'opération représentée à la figure 8, pour passer à l'opération de ligaturage et de conformation de la branche (f) , comme représenté à la figure 9. on transfère dudit convoyeur 18 audit convoyeur 26 ledit groupe d'extrémités B et que l'on positionne de sorte que ladite branche (f) soit sensiblement tendue grâce aux moyens de permutation et d'ordonnancement et de transfert décrits précédemment.With reference to FIG. 8, in order to stretch the terminal branch (a) and allow it to be tied up, in an area located near the end 26a of said conveyor 26, which end 26a is located near said conveyor 18 that is that is to say from the other main conveyor, the group of ends A is moved or transferred on said conveyor 26 and it is moved to the left to a predetermined position, and the groups of are transferred to said conveyor 18 ends B, C, D, E and they are moved to the right to a determined position and respecting a spacing between said groups of ends B, C, D, E so that all of the sections of son constituting the bundle is substantially stretched; in this case and by way of example the distance separating the group of ends A from the group of ends B, which is marked ab, in FIG. 8, will be substantially equal to the sum of the lengths of the terminal branches (a) and B) ; in the same way the distance marked ac in FIG. 8, separating said groups of ends A and C, will be substantially equal to the sum of the lengths of said terminal branches (c) and (a) and to which the length of said length is added. central branch (f). After said branch (a) is ligated by a machine not shown which corresponds to the operation shown in Figure 8, to proceed to the ligating and shaping operation of the branch (f), as shown in FIG. 9. said group of ends B is transferred from said conveyor 18 to said conveyor 26 and positioned so that said branch (f) is substantially stretched by means of permutation and d scheduling and transfer described above.
Pour tendre la branche (e) comme représenté à la figure 10, on conserve le groupe d'extrémités E sur ledit convoyeur 18 et on transfère tous les autres groupes d'extrémités à savoir A, B, C, D sur ledit deuxième convoyeur 26 principal de manière à placer la portion des tronçons de fils formant ladite branche terminale (e) au voisinage de l'extrémité 26a où est situé le dispositif de ligaturage (non représenté) .To tension the branch (e) as shown in FIG. 10, the group of ends E is kept on said conveyor 18 and all the other groups of ends, namely A, B, C, D, are transferred to said second conveyor 26 main so as to place the portion of the sections of son forming said end branch (e) in the vicinity of the end 26a where the ligating device is located (not shown).
On peut ensuite, comme représenté à la figure 11, tendre la branche (g) centrale, en transférant sur ledit convoyeur 18 ledit groupe d'extrémités D tout en conservant sur ledit convoyeur 26 lesdits groupes d'extrémités A, B, C, jusqu'à des positions dans lesquelles les portions de tronçons de fils constituant ladite branche (g) sont sensiblement tendues et permettant ainsi leur ligaturage .It is then possible, as shown in FIG. 11, to stretch the central branch (g), by transferring onto said conveyor 18 said group of ends D while preserving on said conveyor 26 said groups of ends A, B, C, up to 'at positions in which the portions of sections of son constituting said branch (g) are substantially stretched and thus allowing their binding.
Comme représenté figure 12 on peut ensuite tendre et ligaturer la branche (c) terminale comportant à une extrémité le groupe d'extrémités C et à l'autre extrémité le noeud N2, en transférant sur le convoyeur 18 le* groupe d'extrémités C et en transférant sur le convoyeur 26 les groupes d'extrémités A, B, D, E, jusqu'à une position dans laquelle les tronçons de fils constituant la branche (c) sont sensiblement tendus et situé dans une zone à proximité du dispositif de ligaturage.As shown in FIG. 12, it is then possible to tension and tie the terminal branch (c) comprising at one end the group of ends C and at the other end the node N2, by transferring the * group of ends C to the conveyor 18 by transferring on the conveyor 26 the groups of ends A, B, D, E, to a position in which the sections of son constituting the branch (c) are substantially stretched and located in an area close to the ligating device .
Afin de ligaturer la branche terminale (d) située entre ledit noeud N3 et ledit groupe d'extrémités D, on transfère comme représenté à la figure 13 ledit groupe d'extrémités D sur ledit convoyeur 18 et on transfère les autres groupes d'extrémités A, B, C, E sur ledit convoyeur 26, jusqu'à des positions dans lesquelles les portions de tronçons de fils constituant ladite branche terminale (d) sont sensiblement tendus et autorisent ainsi son ligaturage.In order to tie the terminal branch (d) located between said node N3 and said group of ends D, said group of ends D is transferred as shown in FIG. 13 onto said conveyor 18 and the other groups of ends A are transferred , B, C, E on said conveyor 26, to positions in which the portions of sections of son constituting said terminal branch (d) are substantially stretched and thus allow its binding.
On termine ensuite le ligaturage de la dernière branche b terminale du faisceau, en transférant comme représenté à la figure 14 le groupe d'extrémité B sur le convoyeur 26 et en transférant les groupes d'extrémités A, C, D, E sur le convoyeur 18, en plaçant lesdits groupes dans des positions relatives dans lesquelles les portions de tronçons de fils constituant ladite branche (b) sont sensiblement tendus.The binding of the last terminal branch b of the bundle is then finished, by transferring the end group B to the conveyor 26 as shown in FIG. 14 and by transferring the end groups A, C, D, E to the conveyor 18, placing said groups in relative positions in which the portions of sections of son constituting said branch (b) are substantially tensioned.
Par référence à la figure 21, on voit que selon un mode préférentiel de réalisation, lesdits convoyeurs intermédiaires (39 et 40 par référence à la figure 6 notamment), peuvent, lorsqu'ils sont dans la position intercalée ou alignée avec lesdits convoyeurs principaux amont et aval, être entraînés de façon synchrone avec l'un desdits convoyeurs amont ou aval, par l'intermédiaire d'un dispositif de crabotage représenté sur cette figure 21.With reference to FIG. 21, it can be seen that according to a preferred embodiment, said intermediate conveyors (39 and 40 with reference to FIG. 6 in particular), can, when they are in the position inserted or aligned with said main upstream conveyors and downstream, be driven synchronously with one of said upstream or downstream conveyors, by means of a dog clutch shown in this FIG. 21.
Sur cette figure on voit en effet que ledit convoyeur 18 qui s'étend selon ledit axe XXI, comporte un courroie crantée 19 munie de crans 48 espacés d'un pas 49, laquelle courroie est entraînée en rotation et supportée par une poulie ou rouleau 20 dudit convoyeur susceptible de tourner selon un axe de rotation YY1 ; une poulie 59 montée sur un arbre commun à ladite poulie 20 est entraînée simultanément à ladite poulie 20 et entraine elle même par l'intermédiaire d'une courroie 57 une poulie 58 d'axe YY2 parallèle audit axe YY1, laquelle poulie 58 entraine une pièce tournante 55 munie d'une rainure en creux 56 ; lorsque ledit convoyeur intermédiaire 39 ou 40 est mis dans une position où il est intercalé entre lesdits convoyeurs amont et aval, lequel convoyeur intermédiaire peut être simplement réalisé par un pignon denté 50 muni de dents 51 ayant un pas circonférentiel 5 qui est voisin dudit pas 49 desdites courroies crantées, ledit pignon et/ou ledit convoyeur 39 peut être mis en mouvement grâce à une pièce tournante 53 Qui est solidaire en rotation selon un axe YY2 dudit pignon denté 50 dudit convoyeur intermédiaire 39 ; lorsque ledit convoyeur intermédiaire 39 est déplacé selon ledit axe ZZ1 jusqu'à ce que l'axe de rotation dudit pignon 50 vienne coïncider avec l'axe de rotation YY2 de ladite poulie 58 du dispositif d'entraînement, la pièce tournante 53 solidaire en rotation dudit pignon 50 et munie sur sa face externe soit d'une rainure protubérante 5 soit d'ergots excentrés remplissant la même fonction, vient coopérer avec la rainure en creux 6 prévue sur la pièce 55 de manière à permettre un entraînement en rotation de ladite pièce 53 et par conséquent dudit pignon denté par ledite poulie 58 selon un type d'accouplement généralement connu sous le nom de H0LDAM, ce qui permet d'éviter une motorisation séparée dudit convoyeur intermédiaire 39 permettant le transfert des supports de groupes d'extrémités de l'un vers l'autre desdits convoyeurs principaux amont et aval. Par référence à la figure 22, les deux convoyeurs principaux 18 et 26 comportent une courroie 19, respectivement 27, munie de crans 48A sur sa face externe et de crans 48B sur sa face interne ; ainsi, lesdites bandes ou courroies 19, 27 entraînées par lesdits rouleaux ou poulies 20, 28 munies de dents 20 A, 2δA, peuvent provoquer des déplacements selon les flèches 32, 33> dans l'un ou l'autre sens en fonction de signaux de commande d'avance ou de recul, desdits supports 23, 24 (partiellement représentés) desdits groupes d'extrémités, par engrènement des plots 47 des bases desdits supports avec les dents ou crans 48 ; les axes YY1 , YY2, YY3, parallèles entre eux, de rotation respectivement desdits rouleaux et pignon 20, 50 B et 28, sont perpendiculaires auxdits axes XXI et ZZ1. Dans la position représentée à la figure 22 où ledit convoyeur intermédiaire 40 est aligné, par sa face supérieure 40 C (servant de plan de glissement auxdits supports) avec les faces supérieures 18 C et 26 C desdits convoyeurs 18, 26, lesdits supports 23, 24 peuvent être transférés de l'un à l'autre desdits convoyeurs ; il est bien sur nécessaire que lesdits pas 49, 47A (des plots 47) et 52 soient égaux, et que la distance 60 séparant lesdits axes YY1 et YY2 ou YY2 et YY3 soit voisine de (ou au moins égale à) la longueur 61 des bases desdits supports 23, 24, 25. On voit sur cette figure que lesdits convoyeurs intermédiaires mobiles 39 et 40 peuvent être reliés à une tige 43 (partiellement représentée) entrainée en translation selon ledit axe ZZ1 par un seul vérin (non représenté) . In this figure we see indeed that said conveyor 18 which extends along said axis XXI, comprises a toothed belt 19 provided with notches 48 spaced apart by a pitch 49, which belt is rotated and supported by a pulley or roller 20 said conveyor capable of rotating along an axis of rotation YY1; a pulley 59 mounted on a shaft common to said pulley 20 is driven simultaneously with said pulley 20 and drives itself by means of a belt 57 a pulley 58 of axis YY2 parallel to said axis YY1, which pulley 58 drives a part rotating 55 provided with a hollow groove 56; when said intermediate conveyor 39 or 40 is placed in a position where it is interposed between said upstream and downstream conveyors, which intermediate conveyor can simply be produced by a toothed pinion 50 provided with teeth 51 having a circumferential pitch 5 which is close to said pitch 49 said toothed belts, said pinion and / or said conveyor 39 can be set in motion by means of a rotating part 53 which is rotationally integral along an axis YY2 of said toothed pinion 50 of said intermediate conveyor 39; when said intermediate conveyor 39 is moved along said axis ZZ1 until the axis of rotation of said pinion 50 comes to coincide with the axis of rotation YY2 of said pulley 58 of the drive device, the rotating part 53 integral in rotation of said pinion 50 and provided on its external face either with a protruding groove 5 or with eccentric lugs fulfilling the same function, comes to cooperate with the hollow groove 6 provided on the part 55 so as to allow a rotary drive of said part 53 and consequently of said pinion toothed by said pulley 58 according to a type of coupling generally known under the name of H0LDAM, which avoids a separate motorization of said intermediate conveyor 39 allowing the transfer of the end group supports from one to the other of said main upstream and downstream conveyors. With reference to FIG. 22, the two main conveyors 18 and 26 comprise a belt 19, respectively 27, provided with notches 48A on its external face and notches 48B on its internal face; thus, said bands or belts 19, 27 driven by said rollers or pulleys 20, 28 provided with teeth 20 A, 2δA, can cause displacements according to arrows 32, 33 > in one or the other direction depending on signals for controlling in advance or in reverse, said supports 23, 24 (partially shown) of said groups of ends, by meshing studs 47 of the bases of said supports with teeth or notches 48; the axes YY1, YY2, YY3, parallel to each other, of rotation of said rollers and pinion 20, 50 B and 28 respectively, are perpendicular to said axes XXI and ZZ1. In the position shown in FIG. 22 where said intermediate conveyor 40 is aligned, by its upper face 40 C (serving as a sliding plane for said supports) with the upper faces 18 C and 26 C of said conveyors 18, 26, said supports 23, 24 can be transferred from one to the other of said conveyors; it is of course necessary that said steps 49, 47A (of pads 47) and 52 are equal, and that the distance 60 separating said axes YY1 and YY2 or YY2 and YY3 is close to (or at least equal to) the length 61 of bases of said supports 23, 24, 25. It can be seen in this figure that said mobile intermediate conveyors 39 and 40 can be connected to a rod 43 (partially shown) driven in translation along said axis ZZ1 by a single jack (not shown).
