Description

PINCE A FUTCLAMP AT FUT

La presente invention est relative a une pince pour fat equipe d'au moins un rebord en partie haute, destinee a titre montee sur un moyen de levage, comprenant en partie basse une zone d'appui contre le fat, et en partie haute une tete comprenant un boitier, un bec superieur et un bec inferieur, articules par rapport au boitier entre une position ouverte et une position de prise, et destines a pincer le rebord superieur du fat. Dans le domaine de la manutention, lorsqu'il s'agit de deplacer des 10 fats, on utilise generalement des pinces montees sur les fourches de chariots elevateurs pour saisir les fats et permettre leur deplacement. Les fats a deplacer peuvent titre metalliques ou en matiere plastique, vides ou pleins. Par ailleurs, differentes tailles et contenances sont utilisees. Cette diversite est difficile a gerer et jusqu'a present it n'existe a priori pas de 15 pince capable de deplacer tous les types de fats de maniere suffisamment fiable pour permettre leur deplacement sur un sol lisse ou accidente. Les dispositifs existants sont, par exemple, specifiques aux fats metalliques et/ou ne permettent pas de saisir les fats vides et/ou ont une tenue aleatoire en terrain accidente. 20 L'invention a pour but, surtout, de proposer une pince permettant la saisie de fats metalliques et plastiques, vides ou pleins, et ce de maniere fiable meme sur des terrains accidentes. Selon ('invention, une pince pour fat du genre defini precedemment est caracterisee en ce que les deux becs sont articules run par rapport a I'autre, 25 les moyens d'articulation des becs sont prevus pour permettre aux deux becs d'effectuer des mouvements de translation run par rapport a I'autre, et des moyens de rappel sollicitent les becs vers la position ouverte. De preference, run des becs comporte au moins un orifice de guidage oblong dans lequel s'engage un piton appartenant a I'autre bec. 30 Le bec inferieur peut titre monte pivotant avec une possibilite d'effectuer par rapport au boitier une translation oblique, proche de la verticale. Le bec inferieur peut titre constitue de deux joues, espacees paralleles, reliees par un mors fixe transversalement dans des degagements des joues, le bec superieur etant loge et guide entre les deux joues. 35 Le bec inferieur peut comporter un piton destine a cooperer avec un orifice inferieur oblong, prevu dans le boitier, dont le grand axe suit une direction oblique.  The present invention relates to a forceps equipped with at least one edge at the top, intended for mounting on a lifting means, comprising in the lower part a bearing zone against the fat, and in the upper part a head comprising a housing, an upper spout and a lower spout, articulated relative to the housing between an open position and a gripping position, and for pinching the upper lip of the fat. In the field of handling, when it comes to moving fats, it is generally used clamps mounted on the forks of forklifts to seize the fats and allow their movement. Fats to be moved may be metal or plastic, empty or full. In addition, different sizes and capacities are used. This diversity is difficult to manage and up to now there is a priori no forceps capable of moving all types of fats reliably enough to allow them to move on smooth or rugged ground. Existing devices are, for example, specific to metal fats and / or do not make it possible to seize empty fats and / or have random behavior in rough terrain. The object of the invention is, above all, to provide a gripper enabling the gripping of metal and plastic sheets, empty or solid, and this in a reliable manner even on uneven ground. According to the invention, a clamp for fat of the kind defined above is characterized in that the two beaks are articulated run relative to each other, the means of articulation of the beaks are intended to allow the two beaks to perform operations. translation movements run with respect to the other, and biasing means bias the spouts towards the open position Preferably, run spouts comprises at least one oblong guide hole in which engages a peg belonging to the other The lower beak may pivotally tilt with a possibility of making an oblique translation, close to the vertical, relative to the housing The lower beak may constitute two cheeks, parallel spaces, connected by a fixed jaw transversely in release of the cheeks, the upper beak being housed and guided between the two cheeks 35 The lower beak may comprise a stud designed to cooperate with a lower oblong hole, provided in the housing, whose main axis is t an oblique direction.

Le mouvement du bec superieur par rapport au boitier peut titre en partie une translation. Le bec superieur peut comporter un piton destine a cooperer avec un orifice superieur oblong, prevu dans le boitier, dont le grand axe est sensiblement horizontal. Le bec superieur peut titre escamote Iorsque la pince est au repos. Au moins un moyen de rappel elastique peut titre prevu entre chaque bec et le boitier. Chaque moyen de rappel elastique peut titre constitue par un ressort prevu entre run des becs et le boitier. D'autres caracteristiques et avantages de !'invention apparaitront dans la description qui suit avec reference aux dessins annexes mais qui n'a aucun caractere limitatif. Sur ces dessins : Fig. 1 est une vue en elevation laterale d'une pince selon ('invention montee sur un chariot elevateur, saisissant un fat, Fig. 2 est une vue en elevation a plus grande echelle de la tete de la pince de Fig. 1 au repos, le boitier etant ouvert. Fig. 3 est une vue similaire a Fig. 2 representant la pince en phase 20 de fermeture sur un rebord de fut. Fig. 4 est une vue similaire a Fig. 2 representant la pince refermee sur un rebord de fat, et Fig. 5 est une vue en perspective de deux pinces similaires a celle illustree Fig. 1 assemblees de maniere a pouvoir saisir deux fats 25 simultanement. En se referant a Fig. 1, on peut voir un chariot elevateur C utilise comme moyen de levage sur lequel est installee une pince P. La pince P est engagee sur les fourches H du chariot elevateur C. La pince P comporte en partie basse une zone d'appui A contre un 30 fat F et en partie haute une tete 1 comprenant un mecanisme destine a pincer le rebord superieur R du fat F. La tete 1 est rendue solidaire de la zone d'appui A par des profiles metalliques soudes afin de former la pince P. Typiquement, deux profiles creux a section rectangulaire sont engages sur les fourches H du chariot elevateur C 35 et rendus solidaires des fourches H a ('aide de vis de pression V. Ces profiles sont relies entre eux par des traverses de maniere a former une structure support S rigide. Une chaine de securite (non representee) est prevue pour relier le support S au tablier du chariot de maniere a pallier une defaillance des  The movement of the upper beak relative to the case can partly title a translation. The upper spout may include a stud designed to cooperate with an upper oblong hole, provided in the housing, whose major axis is substantially horizontal. The upper beak may be retracted when the clamp is at rest. At least one elastic return means may be provided between each beak and the housing. Each resilient return means may constitute a spring provided between run nose and case. Other features and advantages of the invention will appear in the description which follows with reference to the accompanying drawings but which has no limiting character. In these drawings: 1 is a side elevational view of a gripper according to the invention mounted on a lift truck, grasping a fat, Fig. 2 is an elevational view on a larger scale of the head of the forceps of Fig. 1 at rest, Fig. 3 is a view similar to Fig. 2 showing the clamp in the closing phase on a rim of a barrel, Fig. 4 is a view similar to Fig. 2 showing the clamp clasped on a lip of fat. and Fig. 5 is a perspective view of two grippers similar to that shown in Fig. 1 assembled so as to be able to grip two fingers simultaneously, Referring to Fig. 1, a lift truck C can be seen as a means of The gripper P is engaged on the forks H of the lift truck C. The gripper P comprises in the lower part a support zone A against a fat F and in the upper part a head 1 comprising a mechanism to pinch the upper rim of the fat F. The head 1 is made integral with the a support zone A by welded metal profiles to form the clamp P. Typically, two hollow profiles of rectangular section are engaged on the forks H of the forklift C 35 and made integral with the forks H by means of screws pressure V. These profiles are interconnected by cross members so as to form a rigid support structure S. A safety chain (not shown) is provided to connect the support S to the deck of the carriage so as to compensate for a failure of

vis V. Une potence verticale 0, destinee a supporter la tete 1, est rendue solidaire de la structure support S. La tete 1 est montee reglable en hauteur sur la potence 0 qui comporte, par exemple, une serie de trous de fixation K, espaces verticalement. La potence 0 est renforcee par deux tirants T.  V. A vertical bracket 0, intended to support the head 1, is secured to the support structure S. The head 1 is mounted height-adjustable on the bracket 0 which comprises, for example, a series of fixing holes K, spaces vertically. The stem 0 is reinforced by two tie rods T.

La tete 1 (Fig. 2 a 4) comporte un boitier 2 de forme sensiblement parallelepipedique avec deux joues paralleles 2a et 2b rendues solidaires par un fond 2c et un couvercle 2d. Pour la suite de la description on considere que le terme arriere caracterise les objets situes vers le chariot elevateur C tandis que le terme avant caracterise les objets situes vers le fat F a saisir. Les termes haut et bas sont entendus lorsque la pince P est pree a fonctionner. La face avant 2e du boitier 2 est ouverte. Un bec superieur 3 et un bec inferieur 4 sont loges dans le boitier 2 entre les joues 2a et 2b. Les extremites des becs 3 et 4 peuvent emerger du boitier 2 par la face avant 2e.  The head 1 (Figures 2 to 4) comprises a housing 2 of substantially parallelepipedic shape with two parallel cheeks 2a and 2b made integral by a bottom 2c and a lid 2d. For the rest of the description, it is considered that the term rear characterizes the objects situated towards the forklift C while the term before characterizes the objects situated towards the fat F to be grasped. The terms up and down are heard when the clamp P is ready to work. The front face 2e of the housing 2 is open. An upper spout 3 and a lower spout 4 are housed in the housing 2 between the cheeks 2a and 2b. The ends of the spouts 3 and 4 can emerge from the housing 2 by the front face 2e.

Le bec superieur 3 est constitue d'une plaque de tole rectangulaire 3a prolongee, au niveau de sa partie avant, par un bec ou un mors 3b rapporte. Les faces de la plaque 3a sont disposees de maniere parallele aux joues 2a et 2b. On designe par 3c I'axe geometrique longitudinal de la plaque 3a. Le mors 3b est constitue essentiellement d'un rectangle de tole dont les faces sont perpendiculaires aux joues 2a et 2b et perpendiculaires a ('axe 3c. Dans sa partie arriere, le bec 3 comporte un teton cylindrique 5, d'axe perpendiculaire aux joues 2a et 2b et secant avec ('axe 3c, traversant la plaque 3a de part et d'autre. Un teton 6 est prevu, traversant la plaque de part en part, sensiblement au tiers de la longueur de la plaque 3a, dans la partie arriere. Le bec inferieur 4 est constitue de deux joues de tole espacees, paralleles,sensiblement triangulaires 4a. Le bec superieur 3 est loge et guide entre les deux joues du bec inferieur 4. Les trois sommets du triangle seront nommes en fonction de leur position lorsque la pince P est au repos. On note 4R la zone du sommet situe le plus en arriere, 4V la zone du sommet situe le plus en avant et 4S la zone du sommet situe le plus bas. Le teton 5 est loge dans des orifices oblongs 7 horizontaux prevus dans les joues 2a et 2b. Le teton 6 est loge dans des orifices oblongs 8 prevus en vis-a-vis dans le bec inferieur 4. Un ressort de rappel de traction 3d, notamment helicoidal, est fixe d'une part a ('arriere de la partie superieure du boitier 2 et d'autre part dans la partie avant du bec superieur 3.  The upper spout 3 is constituted by a rectangular sheet metal plate 3a extended at its front portion by a spout or jaw 3b reported. The faces of the plate 3a are arranged parallel to the cheeks 2a and 2b. 3c denotes the longitudinal geometric axis of the plate 3a. The jaw 3b consists essentially of a rectangle of sheet whose faces are perpendicular to the cheeks 2a and 2b and perpendicular to the axis 3c.In its rear part, the spout 3 comprises a cylindrical teat 5, with an axis perpendicular to the cheeks 2a and 2b and secant with (3c axis, passing through the plate 3a on either side .Teton 6 is provided, passing through the plate from side to side, substantially one-third of the length of the plate 3a, in the part The lower beak 4 consists of two parallel, substantially triangular, sheet-shaped cheeks 4a, the upper beak 3 being housed and guided between the two cheeks of the lower beak 4. The three vertices of the triangle will be named according to their position. when the gripper P is at rest, 4R is the zone of the vertex situated furthest back, 4V the zone of the summit situated furthest forward, and 4S the zone of the summit situated at the lowest point, the teton 5 is housed in orifices. horizontal oblong 7 in the cheeks 2a and 2b. 6 is housed in oblong orifices 8 provided in facing relation to the lower spout 4. A pulling spring 3d, in particular helical, is fixed on the one hand to the rear of the upper part of the casing 2 and on the other hand in the front part of the upper spout 3.

Au voisinage de la zone 4R, se trouvent les orifices oblongs 8, prevus de maniere sensiblement parallele a la tangente en 4R a un cercle centre vers la zone 4S. Au voisinage de la zone 4S, le bec 4 comporte un teton cylindrique 9, d'axe parallele aux tetons 5 et 6, faisant saillie de part et d'autre des joues 4a. Le teton 9 est loge dans des orifices oblongs 10 prevus dans les joues 2a et 2b. Les orifices oblongs 10 sont inclines par rapport a la verticale d'un angle assez faible generalement inferieur a 45 . Au voisinage de la zone 4V, les joues 4a sont reliees par un mors 4b constitue essentiellement d'un rectangle de We dont les faces sont perpendiculaires aux joues 4a, et faisant saillie vers le haut. Le mors 4b fait aussi office d'entretoise entre les joues 4a. Des degagements 4d sont prevus dans les joues 4a de maniere a pouvoir mettre en place le mors 4b. Les parties inferieures 4e des degagements 4d font ainsi office de siege pour le mors 4b et permettent de transmettre efficacement aux joues 4a les efforts importants du fat F sur le mors 4b. Un ressort de rappel de traction 4c, notamment helicoidal, est fixe dune part a I'arriere du boitier 2, (Fig. 2), et d'autre part au voisinage de 4R. Le fonctionnement de la pince illustre sur Fig. 2 a 4 est le suivant.  In the vicinity of the area 4R are the oblong holes 8, provided substantially parallel to the tangent at 4R has a center circle to the area 4S. In the vicinity of the zone 4S, the spout 4 comprises a cylindrical teton 9, axis parallel to the teats 5 and 6, protruding from both sides of the cheeks 4a. The teton 9 is housed in oblong holes 10 provided in the cheeks 2a and 2b. The oblong orifices 10 are inclined to the vertical at a rather low angle generally below 45. In the vicinity of the zone 4V, the cheeks 4a are connected by a jaw 4b is essentially a rectangle of We whose faces are perpendicular to the cheeks 4a, and projecting upwards. The jaw 4b also acts as a spacer between the cheeks 4a. Discharges 4d are provided in the cheeks 4a so as to be able to set up the jaw 4b. The lower parts 4e 4d clearances and serve as seat for the bit 4b and can effectively transmit to the cheeks 4a the important efforts of fat F on the jaw 4b. A traction return spring 4c, in particular helicoidal, is fixed on the one hand to the rear of the housing 2, (FIG 2), and on the other hand in the vicinity of 4R. The operation of the clamp illustrates in FIG. 2 to 4 is the following.

Sur Fig. 2, on peut voir, qu'au repos, le ressort de rappel 3d maintient le bec 3 dans une position rentree entre les joues 2a et 2b. Le bec superieur 3 est totalement escamote a I'interieur du boitier 2 de maniere a faciliter les manoeuvres d'approche. Le teton 5 se trouve a I'arriere des orifices oblongs 7. Le ressort de rappel 4c et ('action du teton 6 du bec superieur 3 sur les orifices oblongs 8 maintiennent le bec inferieur 4 sensiblement a I'interieur du boitier 2, le mors 4b restant en saillie a I'exterieur. Le teton 6 se trouve sensiblement au centre des orifices oblongs 8. L'operateur conduit le chariot elevateur equipe sur sa fourche de la pince P de maniere a amener le mors 4b du bec inferieur 4 au contact du fat, 30 sous le rebord superieur R du fat F. L'operateur commande alors la montee de la fourche de son chariot de maniere a deplacer la pince P et notamment la tete 1 selon un mouvement de translation verticale vers le haut. Fig. 3, on constate que le mors 4b entre en contact avec la partie 35 inferieure du rebord R. L'effort exerce par le rebord R sur le mors 4b provoque la translation vers le bas du bec inferieur 4 par rapport au boitier 2 et au bec superieur 3. Le teton 9 progresse vers le bas a I'interieur des orifices oblongs 10. Les orifices oblongs 8 glissent vers le bas autour du teton 6 jusqu'e ce que  In Fig. 2, it can be seen that at rest, the return spring 3d maintains the spout 3 in a position entered between the cheeks 2a and 2b. The upper spout 3 is completely retracted into the interior of the casing 2 so as to facilitate the approach maneuvers. The teton 5 is located at the rear of the oblong orifices 7. The return spring 4c and the action of the teton 6 of the upper spout 3 on the oblong orifices 8 maintain the lower spout 4 substantially inside the housing 2, the 4b jaw remaining outside projecting The teton 6 is substantially in the center of the oblong orifices 8. The operator drives the forklift equipped on its fork of the clamp P to bring the jaw 4b of the lower nose 4 to contact the fat, 30 under the upper rim of fat F. The operator then controls the raising of the fork of his carriage so as to move the clamp P and in particular the head 1 in a vertical translation movement upwards. 3, it can be seen that the jaw 4b comes into contact with the lower part of the rim R. The force exerted by the rim R on the jaw 4b causes the downward translation of the lower beak 4 with respect to the case 2 and the upper spout 3. The teton 9 progresses downward within the ori oblong slots 10. The oblong holes 8 slide down around the teton 6 until

le teton 6 se bloque dans la partie superieure des orifices oblongs 8. Par la suite, alors que le boitier 2 continue a monter, I'action du bec inferieur 4, arrete par le rebord R, sur le bec superieur 3 par I'intermediaire du teton 6 provoque le pivotement vers le bas du bec superieur 3 autour du teton 5. Sur Fig. 4, on peut voir que le mouvement de translation vers le haut de la tete 1 se poursuivant, I'action du bec inferieur 4 sur le bec superieur 3 persiste. Le bec superieur 3 continue de pivoter jusqu'a entrer en contact avec la partie superieure du rebord R, qui se trouve serre entre le bec inferieur 4 et le bec superieur 3. Le logement 7 guide le teton 5 et permet ainsi au bec superieur 3 d'effectuer une translation de faible ampleur vers I'arriere et de s'adapter au profil du rebord R et de bien le serrer. La poursuite du mouvement de translation vers le haut de la tete 1 entraine ('ensemble des pieces de la tete 1 et le fiat F, le rebord R etant bloque entre les becs 3 et 4. Le fiat F decolle donc du sol, soutenu par les becs 3 et 4, et pivote autour de la zone du rebord R en prise entre les mors 3b et 4b, son centre de gravite ayant naturellement tendance a venir se placer sous la zone du rebord R en prise. Le mouvement de pivotement du fiat F I'amene a entrer en contact avec la zone d'appui A (Fig. 1) de la pince P. Le fiat est donc maintenant maintenu par les mors 3b et 4b et en butee sur la zone d'appui A. Cette position stable permet de le deplacer en securite. II est important de preciser que pour que la prise soit efficace, ('orifice oblong 10 doit titre suffisamment long pour que le teton 9 ne puisse pas se bloquer en partie basse et qu'un jeu subsiste entre le teton 9 et le fond de 1'orifice 10 comme visible sur Fig. 4. La geometrie des differents elements composant la tete 1 doit titre definie pour eviter que le teton 6 ne se trouve en arriere du teton 7. Le teton 6 doit titre suffisamment en avant pour garantir un pivotement vers ('avant du bec superieur. Les fiats a transporter ont generalement une forme cylindrique. Le bec inferieur 4, qui entre en contact le premier avec le fat F a deplacer, sert en quelque sorte de palpeur pour le bec superieur. En effet du fait de la liaison entre les deux becs par I'intermediaire du teton 6 et des orifices 8, la position du bec superieur est toujours fonction de celle du bec inferieur. Mais les orifices 7 et 8 permettent au bec superieur 3 de mieux s'adapter au profil du fat F et de son bord R. Sur Fig. 5, on peut voir qu'il est possible d'utiliser deux pinces avec  the teton 6 locks in the upper part of the oblong holes 8. Subsequently, while the casing 2 continues to rise, the action of the lower beak 4, stopped by the rim R, on the upper spout 3 through the intermediary teton 6 causes the pivoting down of the upper spout 3 around the teton 5. In FIG. 4, it can be seen that the upward translation movement of the head 1 continues, the action of the lower beak 4 on the upper beak 3 persists. The upper spout 3 continues to pivot until it comes into contact with the upper part of the rim R, which is squeezed between the lower spout 4 and the upper spout 3. The housing 7 guides the teton 5 and thus allows the upper spout 3 make a small displacement towards the rear and adapt to the profile of the rim R and tighten it well. The continuation of the translation movement upwards of the head 1 causes all the parts of the head 1 and the fiat F, the rim R being blocked between the beaks 3 and 4. The fiat F therefore leaves the ground, supported by the spouts 3 and 4, and pivots around the zone of the rim R engaged between the jaws 3b and 4b, its center of gravity having a natural tendency to come under the zone of the rim R engaged. F leads to contact with the bearing area A (Fig. 1) of the clamp P. The fiat is now maintained by the jaws 3b and 4b and abutting on the bearing zone A. This position It is important to specify that for the catch to be effective, the elongated hole 10 must be long enough so that the teton 9 can not lock in the lower part and a gap remains between the teton 9 and the bottom of the orifice 10 as visible in Fig. 4. The geometry of the different elements composing the head 1 d This title is defined to prevent the teton 6 is behind the teton 7. The teton 6 must title sufficiently forward to ensure pivoting to ('before the upper beak. The fiats to carry generally have a cylindrical shape. The lower beak 4, which comes into contact with the first F fat to move, serves as a sort of feeler for the upper beak. Indeed due to the connection between the two nozzles through the teton 6 and 8 orifices, the position of the upper beak is always a function of that of the lower beak. But the orifices 7 and 8 allow the upper spout 3 to better adapt to the profile of fat F and its edge R. In FIG. 5, we can see that it is possible to use two clamps with

deux zones d'appui assemblees sur un meme bati, de maniere a pouvoir transporter simultanement deux Mts. La hauteur des boitiers 2 de chaque pince peut titre reglee separement.5  two support zones assembled on the same frame, so that two Mts can be carried simultaneously. The height of the boxes 2 of each clamp can be controlled separately.5
