Description

SYSTEME DE MANUTENTION RAPIDE SUR LUGES FAST SLEDGE HANDLING SYSTEM
La présente invention concerne un système de manu tention sur luges du type comportant au moins un dispositi de convoyage rapide pour le transfert d'objets, disposé sur les luges, entre des postes de travail où ces objet doivent subir des opérations effectuées par une machin outil ou un robot, sans pour autant décharger les objets d dispositif de convoyage.The present invention relates to a handling system on sleds of the type comprising at least one rapid conveying device for the transfer of objects, disposed on the sleds, between work stations where these objects must undergo operations carried out by a tool machine. or a robot, without unloading the conveying device objects.
Le système est conçu pour permettre des avances rapides des objets et leur positionnement aux postes d'arrêt avec une précision convenable. Il apporte ainsi une solution à un problème qui n'avait pas été résolu par les dispositifs de l'art antérieur, notamment par la description de la demande de brevet britannique GB 2 074 969 A. Dans celle-ci on utilise des courroies de transmission qui sont crantées pour être entraînées par des pignons portés par des arbres entraînés en rotation. La transmission aux objets à déplacer s'effectue par friction au niveau d'une partie lisse des courroies, en contact avec des galets. Mais ce dispositif n'est pas adapté aux systèmes de manutention sur luges car, dans ces derniers, les luges sont entraînées par des rouleaux montés en porte- à-faux de part et d'autre d'un bâti, généralement appelé table.The system is designed to allow rapid advancement of objects and their positioning at stop points with suitable precision. It thus provides a solution to a problem which had not been resolved by the devices of the prior art, in particular by the description of British patent application GB 2 074 969 A. In this one, transmission belts are used which are notched to be driven by pinions carried by shafts driven in rotation. Transmission to objects to be moved takes place by friction at a smooth part of the belts, in contact with rollers. However, this device is not suitable for handling systems on sleds because, in the latter, the sleds are driven by rollers mounted in cantilever on either side of a frame, generally called a table.
En général, ces rouleaux supportent les luges sur lesquelles sont disposés les objets à transférer en même temps qu'ils les entraînent. Il est utile en outre de pouvoir associer dans un même système de manutention, où les objets restent portés par les mêmes luges, à la fois des dispositifs de convoyage rapide entre des postes de travail où les luges sont immobilisées, et des dispositifs de convoyage lent où, au contraire, des opérateurs travaillent sur les objets pendant le déplacement de ceux- ci. ' La présente invention a donc pour objet un système de manutention d'objets portés sur des luges, comportant des dispositifs de convoyage à rouleaux disposés en porte- à-faux de part et d'autre de la ligne de convoyage, caractérisé en ce qu'il comporte au moins un tel dispositif de convoyage rapide entre des postes de travail où les luges sont immobilisées, lesdits rouleaux étant associés dans ce dispositif avec des courroies d'entraînement qui les recouvrent et qui présentent des bords crantés coopérant avec au moins certains desdits rouleaux constituant des poulies motrices disposées aux extrémités du dispositif de convoyage.In general, these rollers support the sleds on which the objects to be transferred are placed at the same time as they entrain them. It is also useful to be able to combine in the same handling system, where the objects remain carried by the same sleds, both rapid conveying devices between work stations where the sleds are immobilized, and slow conveying devices where, on the contrary, operators work on the objects during the displacement of these. The present invention therefore relates to a system for handling objects carried on sleds, comprising roller conveyor devices arranged in cantilever on either side of the conveyor line, characterized in that 'It comprises at least one such rapid conveying device between work stations where the sleds are immobilized, said rollers being associated in this device with drive belts which cover them and which have notched edges cooperating with at least some of said rollers constituting drive pulleys arranged at the ends of the conveying device.
Selon une autre caractéristique, le dispositif de convoyage comporte entre les courroies de convoyage, des moyens de positionnement des luges en position de travail.According to another characteristic, the conveyor device comprises, between the conveyor belts, means for positioning the sleds in the working position.
Selon une autre caractéristique, les moyens de positionnement sont constitués par des plots mobiles, introduits dans des trous du cadre supérieur de la luge sous l'action de cames excentriques montées sur des axes commandés en rotation par une tringlerie actionnée par un vérin.According to another characteristic, the positioning means consist of movable studs, introduced into holes in the upper frame of the sledge under the action of eccentric cams mounted on axes controlled in rotation by a linkage actuated by a jack.
Selon une autre caractéristique, les luges compor¬ tent au moins deux trous de centrage disposés suivant une diagonale de la luge et au plus deux points d'appuis suivant l'autre diagonale.According to another characteristic, the sleds comprise at least two centering holes arranged along a diagonal of the sledge and at most two support points along the other diagonal.
Selon une autre caractéristique les cames sont montées sur deux axes disposés sur le dispositif de convoyage à une distance correspondant à l'intervalle séparant les trous de centrage sur la luge.According to another characteristic, the cams are mounted on two axes arranged on the conveyor device at a distance corresponding to the interval separating the centering holes on the sledge.
Un autre but de l'invention est de proposer un système de manutention rapide qui puisse s'associer également avec des dispositifs de convoyage lent de façon à assurer une flexibilité dans l'emploi des dispositifs de convoyage rapide ou lent.Another object of the invention is to provide a rapid handling system which can also be combined with slow conveying devices so as to provide flexibility in the use of fast or slow conveying devices.
Ce but est atteint par l'utilisation d'une luge spécifiqrue qui comporte un cadre supérieur en tubes soudé sur lesquels sont montés des plots de fixation des objets transporter et des bras en forme de "C, reliés chacun pa une extrémité du "C à un des côtés longitudinaux du cadre l'autre extrémité de chaque "C" étant reliée à un des deu skis disposés avec un écartement correspondant à l'écarte ment des courroies du dispositif de convoyage, les bras e "C" étant montés transversalement à la direction d convoyage et avec leur concavité tournée vers l'intérieu de la ligne de convoyage.This goal is achieved by the use of a sledge specifiqrue which comprises an upper frame in welded tubes on which are mounted studs for fixing transport objects and arms in the shape of "C, each connected by one end of the" C to one of the longitudinal sides of the frame the other end of each "C" being connected to one of the two skis arranged with a spacing corresponding to the spacing of the belts of the conveying device, the arms e "C" being mounted transversely to the conveying direction and with their concavity facing inward. of the conveyor line.
Selon une autre caractéristique, la luge comport des skis de longueur supérieure aux objets à transporter.According to another characteristic, the sledge comprises skis of length greater than the objects to be transported.
On décrira maintenant plus en détail une forme d réalisation particulière de l'invention qui en fera mieu comprendre les caractéristiques essentielles et les avan tages, étant entendu toutefois que cette forme de réali sation est choisie à titre d'exemple et qu'elle n'es nullement limitative. Sa description est illustrée par le dessins annexés, dans lesquels :A particular embodiment of the invention will now be described in more detail which will make it better understand the essential characteristics and the advantages, it being understood however that this embodiment is chosen by way of example and that it does not are in no way limiting. Its description is illustrated by the accompanying drawings, in which:
- la figure 1 représente une vue de dessus d dispositif de convoyage avec poste de positionnement ;- Figure 1 shows a top view of conveyor device with positioning station;
- la figure 2 représente une vue de dessus de l luge spécifique, utilisée avec les dispositifs de convoyage j- Figure 2 shows a top view of the specific sledge, used with the conveyor devices j
- la figure 3 représente une vue en coupe de l'ensemble dispositif de convoyage/luge.- Figure 3 shows a sectional view of the conveyor / sledge assembly.
Le système de manutention que l'on va décrire, en relation avec les figures 1 à 3» permet des vitesses de convoyage de l'ordre de 100 m/mn et un centrage aux postes d'arrêt des luges convoyées.The handling system which will be described, in relation to FIGS. 1 to 3 ” allows conveying speeds of the order of 100 m / min and centering at the stopping points of the sledges conveyed.
Le dispositif de convoyage des figures 1 et 3 est essentiellement constitué par une table à rouleaux comportant deux longerons 21,20 à section en forme de "U", dans lesquels sont montés en rotation des axes d'entraîné- - li ¬ ment 22,<23>24,25, aux deux extrémités desquels sont montées en porte-à-faux des rouleaux 220,230,240,250. Les extrémités de la table des rouleaux sont constituées par des poulies 220 crantées montées sur l'axe d'entraînement 22 sont entraînées au moyen d'une chaîne de transmission 3 et d'un pignon (sans référence) par un moteur 4. Les poulies 250 de l'axe 25, à l'autre extrémité du dispositif de convoyage, permettent de régler la tension des courroies 27>28 au moyen de dispositifs de tension 251 assurant un déplacement dans le sens longitudinal, représenté par la flèche A, des axes de rotation des poulies 250. Les courroies crantées 27 et 28, respectivement engrènent avec les poulies 220 à 250 disposées de part et d'autre à l'extérieur des longerons 21 et 20, respectivement.The conveying device of FIGS. 1 and 3 essentially consists of a roller table comprising two side members 21, 20 with a section in the shape of a "U", in which are driven rotation axes. - l i ¬ 22, <23 > 24.25, at both ends of which are mounted cantilever rolls 220,230,240,250. The ends of the roller table consist of toothed pulleys 220 mounted on the drive shaft 22 are driven by means of a transmission chain 3 and a pinion (without reference) by a motor 4. The pulleys 250 of the axis 25, at the other end of the conveying device, make it possible to adjust the tension of the belts 27 > 28 by means of tensioning devices 251 ensuring a displacement in the longitudinal direction, represented by the arrow A, of the axes of rotation of the pulleys 250. The toothed belts 27 and 28, respectively mesh with the pulleys 220 to 250 arranged on either side outside the side members 21 and 20, respectively.
Le montage en porte-à-faux des poulies à l'extérieur des longerons et les courroies crantées permettent d'assurer à la fois une grande vitesse de fonctionnement sans avoir de glissement de la courroie sur les poulies motrices et d'autre part d'utiliser des luges spécifiques à une installation de manutention à débit lent. Ces installations à débit lent présentent un platelage fixe de protection couvrant les courroies et qui vient se glisser entre les jambes des luges en déplacement de façon à protéger le système de manutention contre les chutes d'objets et à éviter les accidents avec le personnel qui circule le long de la ligne de convoyage.The cantilever mounting of the pulleys outside the side members and the toothed belts ensure both high operating speed without having the belt slip on the drive pulleys and on the other hand use sleds specific to a slow-flow handling installation. These slow-flow installations have a fixed protective deck covering the belts and which slides between the legs of sleds on the move so as to protect the handling system against falling objects and to avoid accidents with personnel on the move. along the conveyor line.
Les luges sont constituées par un cadre formé de deux longerons 101,102, reliés entre eux par des traverses 103 à 105 à proximité desquelles on a monté des bras 106 en forme de "C". L'extrémité des bras 106 qui n'est pas fixée au cadre de la luge est rendue solidaire de patins 108,109 placés à la verticale sous les longerons 102,101 du cadre de la luge. Les bras en "C" sont disposés transversalement à la ligne de déplacement des luges et avec leur concavité tournée vers l'intérieur de la ligne de convoyage. L'écartement des patins 108,109 correspond à l'écartement des courroies 27,28.The sleds are formed by a frame formed by two longitudinal members 101,102, interconnected by crosspieces 103 to 105 near which arms 106 have been mounted in the form of "C". The end of the arms 106 which is not fixed to the frame of the sled is made integral with pads 108, 109 placed vertically under the longitudinal members 102, 101 of the frame of the sled. The "C" arms are arranged transversely to the line of displacement of the sleds and with their concavity turned towards the inside of the conveyor line. The spacing of the pads 108,109 corresponds to the spacing belts 27,28.
Comme on peut le constater sur la figure 3 les poulies d'entraînement 230 comportent une partie lisse 2300 et une partie crantée 2301. La partie lisse coopère avec une partie lisse correspondante sur les courroies tandis que la partie crantée 2301 coopère avec une partie crantée correspondante sur les courroies. La partie lisse de la courroie et des poulies se trouve à l'aplomb des patins 108,109.As can be seen in FIG. 3 the drive pulleys 230 have a smooth part 2300 and a notched part 2301. The smooth part cooperates with a corresponding smooth part on the belts while the notched part 2301 cooperates with a corresponding notched part on the belts. The smooth part of the belt and the pulleys is plumb with the pads 108, 109.
Comme le montre la figure 2, la luge comporte, suivant une diagonale, deux trous de centrage 1050,1040, le premier 1050 se trouvant à proximité du longeron 101 et de la traverse 105, tandis que le second 1040 se trouve à proximité du deuxième longeron 102 et de la traverse 104 située à l'extrémité opposée de la luge. Les trous de centrage 1050,1040 sont réalisés dans des pattes rapportées le long des longerons et traverses, ces pattes étant pourvues desdits trous de centrage 1040,1050. Suivant la même diagonale que les trous de centrage 1050,1040, deux colonnes verticales 51,50 sont rendues solidaires des longerons 21,20 du dispositif de convoyage. Ces colonnes 51,50 dépassent la hauteur des courroies 27,28, mais elles sont de hauteur légèrement inférieure à la hauteur des traverses des luges lorsque celles-ci sont convoyées par le dispositif de convoyage. Ces colonnes 50,51 supportent à coulissement un cadre 5, aux quatre coins desquels sont disposés, soit des plots de centrage 54,55 aux extrémités tronconiques, soit des plots d'appui qui viennent coopérer avec les surfaces d'appui des pattes 1051,1041 solidaires du cadre de la luge et disposées suivant la diagonale opposée à la diagonale des pattes 1050,1040 comportant les trous de centrage. Les plots d'appui ne sont pas représentés ; ils sont constitués par de simples cylindres de hauteur inférieure aux plots de centrage.As shown in Figure 2, the sledge has, along a diagonal, two centering holes 1050.1040, the first 1050 being near the spar 101 and the cross member 105, while the second 1040 is near the second spar 102 and cross member 104 located at the opposite end of the sledge. The centering holes 1050.1040 are produced in tabs attached along the side members and crosspieces, these tabs being provided with said centering holes 1040.1050. Along the same diagonal as the centering holes 1050.1040, two vertical columns 51.50 are made integral with the side members 21.20 of the conveying device. These columns 51.50 exceed the height of the belts 27.28, but their height is slightly less than the height of the crosspieces of the sleds when the latter are conveyed by the conveyor device. These columns 50, 51 support slidingly a frame 5, at the four corners of which are arranged, either centering pads 54.55 at the frustoconical ends, or support pads which cooperate with the support surfaces of the legs 1051, 1041 integral with the frame of the sledge and arranged along the diagonal opposite to the diagonal of the legs 1050.1040 comprising the centering holes. The support pads are not shown; they consist of simple cylinders with a height less than the centering studs.
Les plots de centrage 54,55 (ou les plots d'appui équivalents) comportent à leur extrémité la plus éloignée des pattes d'appui et de centrage, des queues cylindriques 550,540 j 560,570, avec lesquelles viennent coopérer des excentriques 223 montés en vis-à-vis des queues 550,540 ; 560,570 des plots de centrage 55,54 et des plots d'appui 56,57. Les excentriques 223 sont montés aux extrémités des axes 70,60 qui dépassent de part et d'autre des longerons 21,20. Les axes 60,70 sont disposés sur le dispositif de convoyage à une distance correspondant à l'intervalle séparant les trous de centrage 1040,1050 de la luge. Des flasques 71,72 ; 74,75 Î 61,62 j 64,65, solidaires respectivement des axes 70,60, sont entraînés autour d'axes de pivotement 73,76 ; 63,66, par des tringles 8,9 dont les axes d'articulation 63,73 ; 66,76 sont excentrés par rapport aux axes de rotation 70,60 des excentriques 223. Ces tringles 8,9 sont elles-mêmes commandées par un axe de rotation 80 monté de façon excentrique par rapport aux tringles. Cet axe de rotation 80 étant actionné par un vérin 91 relié par un excentrique 90 à cet axe. Lorsque le vérin 91 est actionné, celui-ci provoque par l'excentrique 90 une rotation de l'axe 80. Cette rotation de l'axe 80 engendre, par le biais de l'axe excentrique 83,86, un déplacement des tringles 8,9, qui elles-mêmes provoquent un déplacement des axes excentriques 63,66,76,73-- Ce déplacement des axes excentriques provoque une rotation des axes 60,70 qui eux-mêmes engendrent un déplacement des excentriques 223» Ces excentriques 223 provoquent la montée du cadre 5 qui, par le biais des plots de centrage 55,54 et des plots d'appui 56,57, décolle la luge par rapport aux courroies 27,28 de 5 mm, les hauteurs des plots de centrage 54,55 et des plots d'appuis étant calculées par rapport aux points d'appui sur la luge de façon que cette dernière soit horizontale.Centering studs 54.55 (or equivalent support studs) have the furthest end at their end support and centering tabs, cylindrical tails 550.540 to 560.570, with which the eccentrics 223 cooperate mounted facing the tails 550.540; 560.570 of the centering pads 55.54 and of the support pads 56.57. The eccentrics 223 are mounted at the ends of the axes 70.60 which protrude on either side of the beams 21.20. The axes 60, 70 are arranged on the conveying device at a distance corresponding to the interval separating the centering holes 1040, 1050 from the sledge. Flanges 71,72; 74.75 Î 61.62 to 64.65, respectively secured to axes 70.60, are driven around pivot axes 73.76; 63.66, by rods 8.9, the axes of articulation 63.73; 66,76 are eccentric with respect to the axes of rotation 70,60 of the eccentrics 223. These rods 8,9 are themselves controlled by a axis of rotation 80 mounted eccentrically with respect to the rods. This axis of rotation 80 being actuated by a jack 91 connected by an eccentric 90 to this axis. When the jack 91 is actuated, this causes the eccentric 90 to rotate the axis 80. This rotation of the axis 80 generates, by means of the eccentric axis 83.86, a displacement of the rods 8 , 9, which themselves cause a displacement of the eccentric axes 63,66,76,73-- This displacement of the eccentric axes causes a rotation of the axes 60,70 which themselves generate a displacement of the eccentrics 223 "These eccentrics 223 cause the rise of the frame 5 which, by means of the centering pads 55.54 and of the support pads 56.57, takes off the sled with respect to the belts 27.28 of 5 mm, the heights of the centering pads 54.55 and support pads being calculated relative to the support points on the sledge so that the latter is horizontal.
Les luges comportent de façon connue des plots de montage 107 qui permettent la fixation des objets 1 à transporter. De cette façon le dispositif de convoyage rapide permet l'arrêt et le centrage des luges à un poste donné etr, dès que le cadre, sous l'action des vérins et des excentriques, s'abaisse, les luges sont à nouveau entraî¬ nées par le système à courroies qui défile à sa vitesse propre de 100 m/mn.The sleds comprise in known manner mounting pads 107 which allow the fixing of the objects 1 to be transported. In this way the rapid conveying device allows the stopping and centering of the sleds at a post. given etr, as soon as the frame, under the action of the jacks and eccentrics, lowers, the sleds are again driven by the belt system which runs at its own speed of 100 m / min.
Il est bien évident que le dispositif de convoyage que l'on vient de décrire est particulièrement adapté à l'utilisation avec des luges telles que décrites en relation avec les figures 2 et 3, mais l'on pourrait éventuellement utiliser d'autres luges. Toutefois, ce type de luges permet l'utilisation conjointement avec ce dispositif de convoyage de dispositifs de convoyage plus lents tels que ceux présentant un platelage fixe de protection couvrant les courroies, et qui vient se glisser entre les. jambes des luges en déplacement, de façon à protéger le système de manutention contre les chutes d'objets et à éviter les accidents avec le personnel qui circule le long de la ligne de convoyage et travaille sur les objets au cours de leur déplacement.It is obvious that the conveyor device that has just been described is particularly suitable for use with sleds as described in relation to Figures 2 and 3, but one could possibly use other sleds. However, this type of sledge allows the use in conjunction with this conveying device of slower conveying devices such as those having a fixed protective deck covering the belts, and which comes to slip between them. legs of sleds in movement, so as to protect the handling system against falling objects and to avoid accidents with personnel who circulate along the conveyor line and work on objects during their movement.
