Abstract
Description
La présente invention se rapporte à un dispositif ou pince portative pour la ligature de barres, tiges ou analogues au moyen d'un fil métallique souple.The present invention relates to a portable device or clamp for ligating bars, rods or the like by means of a flexible metallic wire.
La fonction de ces dispositifs est la ligature instantanée des pièces longitudinales, telles que les barres, tiges ou ronds pour armature de béton armé, des grillages métalliques sur fils tendeurs, des câbles électriques en faisceaux groupés ou des branches de végétaux sur fils tuteurs. De façon générale, de telles pinces trouvent l'application dans les domaines de travaux publics, de transport et manutention, de clôtures et d'agriculture ou de jardinage.The function of these devices is the instantaneous ligation of longitudinal pieces, such as bars, rods or rounds for reinforcement of reinforced concrete, metallic grids on tensioning wires, electric cables in bundles or branches of plants on staking wires. In general, such pliers find application in the fields of public works, transport and handling, fencing and agriculture or gardening.
Selon les méthodes usuelles, on utilise des pinces universelles ou des tenailles employées à la main pour ligaturer avec un fil métallique des barres que l'on entoure de fil dont les extrémités sont torsadées par rotations répétées des pinces à la force du poignet. Cette méthode est lente, incommode et peu rentable.According to the usual methods, universal pliers or pincers used by hand are used to tie with a metallic wire bars which are surrounded by wire whose ends are twisted by repeated rotations of the pliers by force of the wrist. This method is slow, inconvenient and unprofitable.
On connait aussi des pinces comportant une drille tournante sur poignée de traction à la main, dont l'extrémité s'engage dans les deux boucles fermées d'un morceau de fil métallique, façonnée mécaniquement au préalable, et que l'on a disposé en demi-cercle autour des barres à lier. La traction effectuée sur la poignée provoque la rotation de la drille et la formation de la torsade de fil métallique qui lie les barres. Cette méthode est également très lente et fatigante.Pliers are also known which include a rotating halyard on a pull handle by hand, the end of which engages in the two closed loops of a piece of metal wire, mechanically shaped beforehand, and which are placed in semicircle around the bars to bind. The traction carried out on the handle causes the rotation of the driller and the formation of the twist of metal wire which binds the bars. This method is also very slow and tiring.
D'autres pinces présentent l'inconvénient déjà signalé, à savoir le fil à lier doit être préalablement conformé en boucle dans une tête de façonnage appropriée de dimensions standard, qui ne peut s'appliquer que pour un volume donné de barres à ligaturer.Other pliers have the drawback already mentioned, namely the wire to be tied must be previously shaped into a loop in a suitable shaping head of standard dimensions, which can only be applied for a given volume of bars to be tied.
La présente invention a pour objet de pallier un tel inconvénient en éliminant la nécessité de façonnage préalable du fil sur un gabarit stan dard.The object of the present invention is to overcome such a drawback by eliminating the need for prior shaping of the wire on a standard template. sting.
Elle concerne plus particulièrement un dispositif pour la ligature de barres, tiges ou analogues au moyen d'un fil métallique souple, muni d'une tête de torsion et de moyens pour l'entrainer en rotation, de pinces ou cisailles et de moyens d'alimentation en fil et qui est caractérisé en ce qu'il comprend un bec supérieur mobile en translation et une gorge pour le calage des barres à lier formée par un bec inférieur fixe et un guide du bec supérieur en forme de fourche, le bec supérieur étant sollicité au moyen d'un ressort en direction du bec inférieur et son extrémité étant constituée par un crochet de préhension, de sorte que, l'extrémité libre du fil de ligature passant par l'ouverture du crochet du bec mobile, le fil soit conformé en boucle de cerclage autour de barres à lier, lorsque le bec mobile contourne les barres à lier, son extrémité conformée en crochet appliquant le fil contre les barres à lier, en suivant exactement leur périmètre groupé.It relates more particularly to a device for ligating bars, rods or the like by means of a flexible metallic wire, provided with a torsion head and means for driving it in rotation, with pliers or shears and means for wire feed and which is characterized in that it comprises an upper spout movable in translation and a groove for the setting of the tying bars formed by a fixed lower spout and a guide of the upper spout in the form of a fork, the upper spout being biased by means of a spring in the direction of the lower beak and its end being constituted by a gripping hook, so that, the free end of the ligature wire passing through the opening of the hook of the movable beak, the wire is shaped in a loop of strapping around the tying bars, when the movable spout bypasses the tying bars, its hook-shaped end applying the wire against the tying bars, exactly following their grouped perimeter.
Ainsi, la tête de ligature ne comportant aucun guide ou gabarit pour conformer le fil en boucle, elle peut être plate, permettant ainsi d'effectuer les ligatures dans les endroits peu accessibles, tels que les angles, et dans toutes les positions, en croix ou en parallèle. Le cerclage de la ligature est fait selon l'invention par contournement des barres à lier et non par le préformage d'une boucle dans une tête gabarit de dimensions fixes.Thus, the ligature head having no guide or template to conform the looped wire, it can be flat, thus making it possible to perform ligatures in places that are not easily accessible, such as the angles, and in all positions, in a cross or in parallel. The strapping of the ligature is made according to the invention by bypassing the bars to be tied and not by preforming a loop in a template head of fixed dimensions.
Par ailleurs, le serrage du fil de la boucle autour des barres à lier est constant, car le crochet du bec mobile tend le fil par coincement glissé. La distance entre les barres et la tête rotative reste toujours la même, d'où une torsade quasi identique pour toutes les ligatures, quel que soit le volume des barres à lier. De cette façon, deux aciers de diamètre de 6 mm ou trois aciers de diamètre de 20 mm peuvent être ligaturés de façon identique, du moment que la longueur du fil délivré pour la ligature est suffisante pour la capacité maximum de la pince à ligaturer.Furthermore, the tightening of the loop wire around the tying bars is constant, because the hook of the movable spout tends the wire by sliding wedging. The distance between the bars and the rotating head always remains the same, resulting in an almost identical twist for all ties, regardless of the volume of the bars to be tied. In this way, two steels with a diameter of 6 mm or three steels with a diameter of 20 mm can be ligated identically, as long as the length of the wire delivered for ligation is sufficient for the maximum capacity of the pliers to ligate.
Selon une forme de réalisation de la pince selon l'invention particulièrement avantageuse, le bec supérieur mobile est constitué de deux plaques en tôle, parallèles, espacées entre elles d'un intervalle supérieur au diamètre du fil servant à lier, un galet reliant vers l'extrémité avant du bec les deux plaques et servant de crochet de préhension et de tirefil de ligature.According to one particularly advantageous embodiment of the clamp according to the invention, the movable upper spout consists of two sheet metal plates, parallel, spaced apart by an interval greater than the diameter of the wire used for binding, a roller connecting towards the 'front end of the spout the two plates and serving as a gripping hook and tie wire.
Ce galet assure le maintien de la tension du fil autour du paquet à lier par coincement glissé, lorsque le bec décrit une trajectoire contournant ledit paquet.This roller maintains the tension of the wire around the bundle to be tied by sliding wedging, when the spout describes a trajectory bypassing said bundle.
De façon avantageuse, la tête de torsion peut présenter un perçage intérieur pour recevoir le brin inférieur du fil, parallèle à l'axe longitudinal de la tête de torsion et une fente le long de la génératrice située dans le plan diamétral du perçage pour recevoir le brin supérieur du fil, avec cliquet de verrouillage empêchant la sortie du brin au cours de la rotation.Advantageously, the torsion head can have an internal bore to receive the lower strand of the wire, parallel to the longitudinal axis of the torsion head and a slot along the generatrix situated in the diametrical plane of the bore to receive the upper side of the wire, with locking pawl preventing the exit of the side during rotation.
Le guidage du fil vers le crochet du bec mobile peut être assuré par une rainure médiane ménagée dans le bec inférieur fixe.The guide of the wire towards the hook of the movable spout can be ensured by a central groove made in the fixed lower spout.
Selon une forme de réalisation avantageuse, la pince comprend deux vérins. Le premier sert à assurer le mouvement de translation aller et retour du bec mobile et l'extrémité de sa tige est articulée sur l'extrémité arrière du bec supérieur mobile.According to an advantageous embodiment, the clamp comprises two jacks. The first serves to ensure the back and forth translation movement of the movable spout and the end of its rod is articulated on the rear end of the movable upper spout.
Le deuxième vérin assure l'entrainement en rotation de la tête de torsion, la tige du vérin exerçant une poussée sur un curseur monté sur une vis spiralée à plusieurs tours solidaire de la tête de torsion.The second cylinder drives the torsion head in rotation, the cylinder rod pushing on a slider mounted on a spiral screw with several turns secured to the torsion head.
Les vérins, à action pneumatique de préférence, peuvent être commandés par une centrale séquentielle.The cylinders, preferably pneumatic, can be controlled by a sequential control unit.

Le carter 1 de la pince pouvant être en matière plastique injectée loge les différentes parties mécaniques dont il sera question puis loin, puis forme à l'avant, d'une part le bec inférieur fixe 2 et, d'autre part, le guide du bec supérieur 4 en forme de fourche.The
Le bec 2 et le guide 4 forment une gorge, au fond de laquelle on place en les calant les barres ou tiges à lier 12.The
Le bec supérieur mobile en translation 3, guidé dans la fourche du bec 2, est constitué de deux plaques de tôle découpée, parallèles et espacées entre elles d'un espace supérieur au diamètre du fil de ligature. L'extrémité du bec présente un axe 16 reliant les deux plaques et portant `un galet rotatif.The upper spout movable in
Le bec 3 est articulé en 5 à l'extrémité de la tige 6 d'un vérin 9 et un ressort 29 sollicite le bec 3 en direction du bec inférieur 2 et sa pression tend à appliquer avec force le bec 3 sur les barres à lier. Le bec inférieur 2 est constitué de trois plaques de tôle accolées dont la plaque centrale découpée en retrait crée une rainure 25 pour le passage du fil de ligature.The
A l'intérieur du carter 1 sont logés deux vérins pneumatiques 7 et 9, ainsi qu'une bobine 13 du fil de ligature en acier recuit.Inside the
Le vérin 7 assure au moyen de sa tige 6 le va-et-vient du bec mobile 3 articulé en 5 à cette tige, l'axe de l'articulation 5 étant guidé horizontalement par un rail solidaire du carter 1.The jack 7 ensures by means of its rod 6 the comings and goings of the
Le vérin 9 assure à la fois l'alimentation du dispositif en fil de ligature et l'entrainement en rotation de la tête de torsion 17.The
Le système d'approvisionnement du fil de ligature comprend un train de trois galets 14 crantés mûs par des engrenages poussés par une crémaillère non représentée actionnée par le vérin 9 et un tube de guidage 15.The system for supplying the ligature wire comprises a train of three
Les galets exercent une pression sur le fil qui glisse sur un patin en matière plastique autolubrifiante.The rollers exert pressure on the wire which slides on a self-lubricating plastic pad.
Lors du mouvent de retour du vérin, les galets sont débrayés au moyen d'un cliquet sur les engrenages pour éviter le retour du fil en arrière. Au dessus du bec inférieur 2 est fixée au moyen de paliers appropriés non représentés une tête de torsion 17 solidaire d'une vis spiralée 21 à plusieurs tours. Sur ladite vis 21 est monté un curseur 20 fixé sur l'extrémité de la tige 8 du vérin 9. Ainsi, lors du déplacement de la tige, la tête de torsion 17 accomplit plusieurs tours de rotation autour de son axe.During the return movement of the jack, the rollers are disengaged by means of a ratchet on the gears to prevent the return of the wire back. Above the
La tête de torsion 17 est constituée d'un cylindre comportant un perçage 27 longitudinal parallèle à l'axe destiné à faire passer le brin inférieur du fil de ligature. Sur le dessus du cylindre, le long de la génératrice diamétralement opposée au perçage 27, se trouve une fente 28 munie d'un cliquet de verrouillage 30 et destinée à recevoir le brin supérieur du fil de ligature.The
Une cisaille coupe-fil 19 est disposée au ras de face intérieure de la tête de torsion 17 pour couper les deux brins de fil. Elle est constituée de deux mâchoires 26 travaillant en opposition et laissant entre elles un évidement pour le passage de la vis spiralée 21 entrainant en rotation la tête de torsion 17.A
L'extrémité de la tige du vérin 9 comporte une came qui écarte les deux bras de la cisaille 19 en glissant entre les deux bossages situés à l'intérieur des bras. Cet écartement provoque la coupe des deux brins de fil. Les deux vérins sont actionnés de préférence par une bouteille d'air comprimé à environ 2 bars et leur action est coordonnée par une centrale séquentielle de temporisation 10 assurant la commande de mouvements alternés et consécutifs.The end of the rod of the
Le fonctionnement de la pince est le suivant.The operation of the clamp is as follows.
En position initiale à l'arrêt du cycle de travail, le bec supérieur 3 est en position représentée à la figure 1, les barres 12 sont placées au fond de la gorge formée par 2 et 4, la pince est approvisionnée de fil de ligature en bobine 13 et le fil est engagé dans les galets pousse-fil 14 et dans le tube de guidage du fil 15 jusqu'au ras de la cisaille 19. On actionne le vérin 9 vers l'avant, ce qui provoque la poussée du fil qui sort du tube 15 par suite d'action des galets crantés 14, pénètre dans le perçage 27 de la tête de torsion 17 et suit la rainure 25 jusqu'à l'extrémité du bec 2. L'action du vérin 9 s'arrête provisoirement là. On fait actionner le vérin 7 vers l'arrière de la pince qui tire le bec supérieur 3 vers l'arrière. En reculant, l'extrémité du fil est happée par le bec supérieur 3 passant sur le galet 16, le fil glisse entre les plaques espacées du bec et, le bec étant appliqué avec force vers bas par le ressort 5, il applique le fil de ligature autour de barres à lier, formant le cerclage épousant exactement le périmètre du paquet de barres à lier.In the initial position when the work cycle stops, the
Lors de sa révolution autour de barres à lier, le brin supérieur de la boucle ainsi formée pénètre dans la fente supérieure 28 de la tête de torsion 17 et y reste retenu par le cliquet 30, tandis que l'extrémité du bec 3 maintient le fil engagé dans la tête de torsion 17.During its revolution around tying bars, the upper strand of the loop thus formed penetrates into the
On arrête l'action du vérin 7 et on actionne le vérin 9 dans le sens opposé à son premier mouvement.The action of the jack 7 is stopped and the
En début de course, le vérin tire en arrière la came de fermeture de la cisaille 19 et les deux brins de la boucle sont coupés. Ensuite, cette came entraine le curseur 20 jusqu'au bout de course, ce qui assure la rotation de la vis 21. La vis spiralée tournant, la tête de rotation 17 exécute plusieurs tours qui forment la torsade de la ligature 18, les deux brins étant freinés. Les extrémités des deux brins glissent hors de la tête 17 et la ligature est terminée, les barres liées sont dégagées. On fait actionner le vérin 7 en sens opposé, par exemple au moyen d'un ressort de rappel, la rotation en sens opposée de la tête 17 n'est pas gênante, car les brins ne sont plus retenus par elle.At the start of the stroke, the jack pulls back the closing cam of the
Le bec supérieur 3 est ainsi ramené à sa position initiale, ce qui permet de placer dans la gorge du bec fixe 2 des barres à lier, pour la ligature suivante.The
Le dispositif selon l'invention est léger et par conséquent portable. Il permet de ligaturer partout où on le désire, seule la dimension des becs de la pince limite son emploi. Il permet également le travail à poste fixe.The device according to the invention is light and therefore portable. It allows you to tie wherever you want, only the size of the pliers' beaks limits its use. It also allows fixed-station work.
