The work platform is provided with two storage areas for pallets of bricks, and an automatic device for manipulating and laying the bricks. The apparatus also includes a palletholder housing comprising at least two compartments for respectively receiving a full pallet and an empty pallet, a basket for carrying the housing, and lifting devices for raising and lowering the basket, together with the pallet-holder housing to the level of the platform and for releasing the pallet-holder housing from the basket. The apparatus is particularly well suited for repairing the refractory lining of a metallurigical convertor.

Description

La présente invention concerne une installation automatisée de briquetage de la paroi intérieure d'une enceinte, comprenant une plate-forme de travail déplaçable verticalement à l'intérieur de l'enceinte et capable de tourner autour de l'axe vertical de celle-ci et pourvue de deux aires de stockage de palettes de briques et de moyens automatiques de manipulation et de pose des briques.The present invention relates to an automated installation for briquetting the inner wall of an enclosure, comprising a working platform which can be moved vertically inside the enclosure and capable of rotating around the vertical axis thereof and provided with two brick pallet storage areas and automatic bricks handling and laying facilities.

Quoique n'y étant pas limitée, l'invention vise plus particulièrement une installation pour la pose d'un garnissage réfractaire sur la paroi intérieure d'un convertisseur métallurgique.Although not limited thereto, the invention relates more particularly to an installation for installing a refractory lining on the inner wall of a metallurgical converter.

Diverses installations de ce genre ( voir par exemple DE-AS-1154131 et BE-A-760355 ) on déjà été proposées pour effectuer, de façon automatique, un travail qui, jusqu'à présent, était effectué généralement de façon manuelle dans des conditions extrêmement pénibles.Various installations of this kind (see for example DE-AS-1154131 and BE-A-760355) have already been proposed for performing, automatically, work which, until now, has generally been carried out manually under conditions extremely painful.

Les installations proposées n'ont, malheureuse­ment, pas permis de résoudre tous les problèmes en suspens , de sorte qu'il n'était pas encore possible, jusqu'à présent, de profiter , de façon systématique, de l'automatisation complète du briquetage des convertisseurs.Unfortunately, the proposed installations did not solve all the outstanding problems, so it was not yet possible, until now, to take advantage, in a systematic way, of the complete automation of the briquetting converters.

Il faut rappeler, à ce sujet, que les briques ont une forme tronconique pour pouvoir réaliser des dépôts circulaires conformes à la section du convertisseur. Or, non seulement tous les conver­tisseurs n'ont pas la même taille, mais en plus, le diamètre de chaque convertisseur est variable suivant la hauteur , étant donné qu'ils ont géné­ralement une section verticale sensiblement ovale. Vu qu'il n'est pas possible de fabriquer des briques sur mesure, on fabrique deux types déterminés de briques de conicité différente et, par une alternance judicieuse dans le choix de ces types, on arrive à réaliser les courbures voulues. Ceci signifie qu'il faut disposer, en permanence, de deux palettes de briques, c'est-à-dire une de chaque type, sur la plate-forme de travail afin que le robot de mise en place des briques , puisse automatiquement faire le choix en fonction d'un contrôle automatique de la pose des briques.On this subject, it should be remembered that the bricks have a frustoconical shape in order to be able to produce circular deposits conforming to the section of the converter. However, not only are all the converters not the same size, but in addition, the diameter of each converter is variable according to the height, since they generally have a substantially oval vertical section. Since it is not possible to make custom bricks, we make two specific types of bricks with different taper and, by alternation judicious in the choice of these types, we manage to achieve the desired curvatures. This means that two brick pallets, that is to say one of each type, must be permanently available on the working platform so that the brick placing robot can automatically do the choice according to an automatic control of the laying of bricks.

Les palettes de briques sont montées ou descendues sur la plate-forme au moyen d'un monte­charge et, arrivées au niveau de la plate-forme , elles sont chargées sur un chariot mobile qui les déplace horizontalement sur leur aire de stockage respectif. Or, pour que l'installation puisse fonctionner correctement de façon automatisée. il faut que chaque palette de briques soit toujours placée à un endroit bien précis , que les briques soient toujours arrangées de la même manière et de façon précise sur les palettes et qu'elles soient toujours orientées de la même manière, l'une par rapport à l'autre, et par rapport à la plate-forme et par rapport au robot de manipulation. Cette condition se complique encore d'avantage par le fait que la plate-forme doit pouvoir tourner autour de l'axe central vertical pour permettre au robot d'atteindre toute la périphérie du briquetage. Par conséquent, le système de déplacement des palettes doit fonctionner de façon précise et constante , sans secousse pour éviter un déplacement des briques sur les palettes et éventuellement une chute de celle-ci et doit, en outre, être associé à des moyens de détection pour surveiller , en permanence, la position correcte des palettes et des briques.The pallets of bricks are raised or lowered on the platform by means of a freight elevator and, arrived at the level of the platform, they are loaded on a mobile trolley which moves them horizontally on their respective storage area. However, so that the installation can function correctly in an automated way. it is necessary that each pallet of bricks is always placed in a very precise place, that the bricks are always arranged in the same way and precisely on the pallets and that they are always oriented in the same way, one with respect to each other, and relative to the platform and relative to the handling robot. This condition is further complicated by the fact that the platform must be able to rotate around the vertical central axis to allow the robot to reach the entire periphery of the brickwork. Consequently, the pallet displacement system must operate in a precise and constant manner, without jerking to avoid a displacement of the bricks on the pallets and possibly a fall thereof and must, in addition, be associated with detection means for constantly monitor the correct position of the pallets and bricks.

Un autre problème est celui de l'encombrement de la plate-forme . Lorsque les palettes sont levées sur la plate-forme, les monte-charge et treuils prévus à cet effet sont installés sur la plate-forme et leurs poulies et câbles gênent le mouvement du robot de manipulation et constituent un danger per­manent pour le personnel se trouvant sur la plate-­forme.Another problem is that of the size of the platform. When the pallets are lifted on the platform, the hoists and winches provided for this purpose are installed on the platform and their pulleys and cables obstruct the movement of the handling robot and constitute a permanent danger for the personnel on the platform.

Les palettes vides peuvent également être à l'origine de problèmes d'encombrement. En effet, lorsqu'une palette pleine est montée ou descendue sur la plate-forme, il faut d'abord dégager la palette vide pour pouvoir transférer la palette pleine sur le chariot, avant d'accrocher la palette vide au monte-charge en vue de son évacuation. Une autre possibilité serait de descendre d'abord la palette vide avant de remonter une palette pleine, mais ceci constitue une perte de temps.Empty pallets can also cause congestion problems. In fact, when a full pallet is raised or lowered on the platform, it is first necessary to clear the empty pallet in order to be able to transfer the full pallet to the trolley, before hanging the empty pallet on the goods lift in view of his evacuation. Another possibility would be to lower the empty pallet first before reassembling a full pallet, but this is a waste of time.

Le but de la présente invention est de prévoir une nouvelle installation automatisée du genre décrit dans le préambule , qui permet d'éliminer tous les problèmes exposés ci-dessus.The object of the present invention is to provide a new automated installation of the type described in the preamble, which makes it possible to eliminate all the problems set out above.

Pour atteindre cet objectif, l'invention propose une installation automatisée de briquetage qui est essentiellement caractérisée par une cage porte-palettes comprenant au moins deux compartiments superposés pour recevoir respectivement une palette pleine et une palette vide , un panier pour porter ladite cage et des moyens de levage pour monter ou descendre le panier avec la cage porte-palettes jusqu'au niveau de la plate-forme et pour dégager la cage porte-palettes du panier, ainsi que des moyens pour placer une palette vide dans la cage et en sortir la palette pleine.To achieve this objective, the invention provides an automated briquetting installation which is essentially characterized by a pallet carrier cage comprising at least two superposed compartments for receiving respectively a full pallet and an empty pallet, a basket for carrying said cage and means lifting device to raise or lower the basket with the pallet cage to the level of the platform and to disengage the pallet cage from the basket, as well as means for placing an empty pallet in the cage and removing the full pallet.

Ledit moyen de levage comporte, de préférence, un premier dispositif de levage à treuil, monté sous la plate-forme pour monter le panier et la cage avec une palette de briques vers une position d'attente en-dessous de la plate-forme et un second dispositif de levage également monté sous la plate-­forme pour sortir la cage porte-palettes du panier et la hisser à travers une ouverture centrale , prévue à cet effet dans la plate-forme, jusqu'au niveau de celle-ci.Said lifting means preferably comprises a first hoist lifting device, mounted under the platform for mounting the basket and the cage with a pallet of bricks to a waiting position below the platform and a second lifting device also mounted under the platform to take the pallet cage out of the basket and hoist it through a central opening, provided for this purpose in the platform, up to the level thereof.

Les deux dispositifs de levage étant montés sous la plate-forme, leurs câbles et treuils n'en­combrent pas la surface de la plate-forme et ne gênent pas le mouvement du robot de dépalettisation et de mise en place des briques. Ce n'est que grâce à la conception particulière du monte-charge sous forme de deux dispositifs de levage séparés que tout le système a pu être arrangé sous la plate-­forme et qu'il soit, néanmoins, en mesure de hisser les palettes jusqu'au niveau de la plate-forme. Par ailleurs, cette conception particulière du système de levage n'a été rendue possible que grâce à la cage porte-palettes et son panier de transport, le premier dispositif de levage agissant sur le panier, tandis que le second agissant sur la cage.The two lifting devices being mounted under the platform, their cables and winches do not clutter the surface of the platform and do not hinder the movement of the depalletizing robot and placing bricks. It is only thanks to the special design of the goods lift in the form of two separate lifting devices that the whole system has been able to be arranged under the platform and that it is nevertheless able to hoist the pallets up to 'at platform level. Furthermore, this particular design of the lifting system has only been made possible thanks to the pallet cage and its transport basket, the first lifting device acting on the basket, while the second acting on the cage.

La cage porte-palettes , qui est l'une des caractéristiques de la présente invention, est conçue sous forme d'étagère à quatre pieds, d'une profondeur sensiblement égale à la longueur des briques, avec un compartiment inférieur pour les palettes pleines et un compartiment supérieur pour les palettes vides.The pallet rack, which is one of the characteristics of the present invention, is designed as a four-legged shelf, of a depth substantially equal to the length of the bricks, with a lower compartment for full pallets and an upper compartment for empty pallets.

Le dessus de la cage est, de préférence, conçu comme bac pour recevoir les briques cassées.The top of the cage is preferably designed as a container for receiving broken bricks.

Le panier , qui est également l'une des carac­téristiques de l'invention, comporte un tablier rectangulaire correspondant sensiblement à la section horizontale de la cage et pourvu aux quatres coins d'encoches pour le passage des pieds de la cage, deux panneaux verticaux sur les côtés longitudinaux opposés du tablier et dont la hauteur est au moins égale à la hauteur du compartiment inféreur de la cage et des anses sur les côtés latéraux opposés du tablier pour attacher les câbles de levage dudit premier dispositif de levage.The basket, which is also one of the characteristics of the invention, comprises a rectangular apron corresponding substantially to the horizontal section of the cage and provided at the four corners with notches for the passage of the feet of the cage, two vertical panels on the opposite longitudinal sides of the apron and whose height is at least equal to the height of the lower compartment of the cage and of the handles on the opposite lateral sides of the apron for attaching the lifting cables of said first lifting device.

Les panneaux verticaux du panier ont de pré­férence une hauteur correspondant à la somme de la hauteur du compartiment inférieur et à la moitié de la hauteur du compartiment supérieur. De cette manière, le compartiment inférieur de la cage est complètement fermé et le compartiment supérieur est au moins partiellement fermé lorsque la cage est engagée dans le panier , ce qui empêche les briques et éventuellement la palette de glisser hors de la cage lorsque celle-ci n'est pas soulevée horizontalement ou qu'elle oscille lorsqu'elle est pendue au câble de levage ou qu'elle heurte un obstacle. Un autre avantage de cette conception du panier est que les palettes doivent être correctement positionnées dans la cage et les briques doivent également être positionnées correctement sur la palette , sans dépassement latéral, faute de quoi il n'est pas possible d'en­gager la cage sur le panier ou vice-versa. Les anses du panier ont une hauteur au moins égale à la moitié de la hauteur du compartiment inférieur de la cage porte-palettes. Par cette mesure , on a l'assurance que le centre de gravité de l'ensemble du panier et de la cage se trouve en-­dessous des points d'attache des câbles de levage , ce qui améliore la stabilité lors du levage et de la descente .The vertical panels of the basket preferably have a height corresponding to the sum of the height of the lower compartment and to half the height of the upper compartment. In this way, the lower compartment of the cage is completely closed and the upper compartment is at least partially closed when the cage is engaged in the basket, which prevents the bricks and possibly the pallet from sliding out of the cage when the latter is not lifted horizontally or oscillates when hung from the lifting cable or when it hits an obstacle. Another advantage of this basket design is that the pallets must be correctly positioned in the cage and the bricks must also be positioned correctly on the pallet, without lateral overhang, otherwise it is not possible to engage the cage on the basket or vice versa. The basket handles are at least half the height of the lower compartment height of the pallet cage. This measure ensures that the center of gravity of the basket and cage assembly is below the attachment points of the lifting cables, which improves stability during lifting and descent.

Des détecteurs de fin de course sont prévus sur le bord inférieur de l'ouverture centrale de la plate-forme et actionnés par des doigts prévus à des endroits correspondants sur les bords supérieurs des panneaux longitudinaux du panier pour déterminer la position d'attente et commander automatiquement l'arrêt du premier dispositif de levage lorsque ladite position est atteinte. Les détecteurs et les doigts correspondants sont, de préférence, au nombre de quatre et font partie d'un circuit de contrôle permettant de déterminer si les quatre détecteurs ont été actionnés simultanément , c'est-­à-dire de vérifier si la cage arrive horizontalement dans la position d'attente.Limit switches are provided on the lower edge of the central opening of the platform and actuated by fingers provided at corresponding locations on the upper edges of the longitudinal panels of the basket to determine the waiting position and control automatically stop the first lifting device when said position is reached. The detectors and the corresponding fingers are preferably four in number and form part of a circuit control to determine if the four detectors were operated simultaneously, that is to say to check if the cage arrives horizontally in the standby position.

Le second dispositif de levage comporte , selon un mode de réalisation préféré, deux paires de crics pivotants prévues à des endroits corres­pondants respectivement aux positions des quatre pieds de la cage porte-palettes lorsque celle-ci se trouve dans la position d'attente et coulissant verticalement le long de deux paires de rails sous l'action de deux vérins. Chaque paire de crics est montée de façon pivotante sur une traverse , de façon à occuper une position relevée à l'écart des pieds de la cage lorsque le second système de levage est hors service.The second lifting device comprises, according to a preferred embodiment, two pairs of pivoting jacks provided at locations corresponding respectively to the positions of the four feet of the pallet carrier cage when the latter is in the waiting and sliding position. vertically along two pairs of rails under the action of two cylinders. Each pair of jacks is pivotally mounted on a cross member, so as to occupy a raised position away from the feet of the cage when the second lifting system is out of service.

Pour assurer une orientation correcte des palettes et des briques , quelle que soit la position angulaire de la plate-forme, on a prévu, par terre , à l'endroit où les palettes sont prises en charge, un plateau rotatif qui tourne en même temps que la plate-forme mais qui revient toujours automati­quement à une position angulaire de départ. Les palettes peuvent donc être déposées sur le plateau à l'aide d'un chariot élévateur qui peut s'approcher toujours suivant la même direction et le plateau est tourné, avant le montage du panier par les câbles du premier dispositif de levage ,suivant un angle corres­pondant à l'orientation de la plate-forme par rapport à la position de départ.To ensure correct orientation of the pallets and bricks, whatever the angular position of the platform, there is provided, on the ground, at the place where the pallets are supported, a rotating plate which rotates at the same time than the platform but which always automatically returns to an angular starting position. The pallets can therefore be placed on the tray using a forklift which can always approach in the same direction and the tray is rotated, before mounting the basket by the cables of the first lifting device, according to a angle corresponding to the orientation of the platform with respect to the starting position.

D'autres particularités et caractéristiques de l'invention ressortiront de la description détaillée d'un mode de réalisation préféré, présenté ci-dessous, à titre d'illustration , en référence aux figures annexées dans lesquelles :

  • la figure 1 représente schématiquement une vue d'ensemble d'une installation de briquetage de la paroi intérieure d'un convertisseur ;
  • la figure 2 montre une vue partielle , en perspective, de la partie supérieure de l'installation ;
  • la figure 3 montre une vue éclatée , en pers­pective, de la cage porte-palettes et du panier et
  • les figures 4a, 4b, 4c montrent le système de levage de la cage , dans des positions différentes.
Other features and characteristics of the invention will emerge from the detailed description of a preferred embodiment, presented below, by way of illustration, with reference to the appended figures in which:
  • Figure 1 schematically shows an overview of a briquetting installation from the interior wall of a converter;
  • Figure 2 shows a partial perspective view of the upper part of the installation;
  • FIG. 3 shows an exploded perspective view of the pallet cage and the basket, and
  • Figures 4a, 4b, 4c show the cage lifting system, in different positions.

La figure 1 montre un convertisseur métallique 10, constitué d'une paroi métallique 14 avec le début d'un garnissage réfractaire 12, constitué d'un empilement de briques réfractaires posées les unes sur les autres à l'aide d'une installation selon la présente invention.FIG. 1 shows a metal converter 10, consisting of a metal wall 14 with the start of a refractory lining 12, consisting of a stack of refractory bricks placed one on the other using an installation according to the present invention.

Cette installation comporte une plate-forme 16 reposant, par l'intermédiaire d'un roulement 18 sur un support annulaire 20. Ce support 20 est porté par plusieurs, par exemple trois mâts télés­copiques 22, actionnés par voie hydraulique pour monter la plate-forme 16 à travers le fond ouvert du convertisseur 10 et déplacer la plate-forme axialement à l'intérieur du convertisseur. Les mâts téléscopiques 22 peuvent faire partie d'un châssis roulant 24 se trouvant sur le plancher de travail en-dessous du convertisseur.This installation comprises a platform 16 resting, by means of a bearing 18 on an annular support 20. This support 20 is carried by several, for example three telescopic masts 22, actuated hydraulically to mount the platform 16 through the open bottom of the converter 10 and move the platform axially inside the converter. The telescopic masts 22 can be part of a rolling chassis 24 located on the work floor below the converter.

Le support annulaire 20 comporte une série de béquilles radiales 26 pour appuyer le support 20 contre l'intérieur du revêtement réfractaire et stabiliser la plate-forme 16 permettant la rotation de celle-ci par rapport au support 20 sans création de vibrations exagé­rées et éviter des oscillations dues au mouvement du robot.The annular support 20 comprises a series of radial crutches 26 for pressing the support 20 against the interior of the refractory lining and stabilizing the platform 16 allowing the rotation thereof relative to the support 20 without creating exaggerated vibrations and avoiding oscillations due to robot movement.

Les palettes de briques dont deux se trouvent sur la plate-forme 16 et sont identifiées par les références 26 et 28 sont amenées , par exemple, à l'aide d'un élévateur à fourche 30 à la verticale en-dessous de la plate-forme 16. Selon l'une des caractéristiques de l'invention, elles y sont déposées sur un plateau rotatif 32. Ce plateau 32 peut tourner, par l'intermédiaire d'une suspension appropriée, par exemple à galets, autour de l'axe 0 et cette rotation est coordonnée avec celle du plateau 16. Celui-ci doit, en effet, pouvoir tourner autour de l'axe 0 afin que le robot de dépalettisation et de pose des briques, représenté par la référence 34, puisse atteindre tout le pourtour du convertisseur. Par exemple, chaque fois que le robot a achevé un secteur, la plate-forme 16 est avancée d'un certain angle, par exemple de 60° pour que le robot puisse faire le secteur suivant. Le plateau 32 est tourné en même temps que la plate-forme 16 du même angle, mais, lorsque le chariot 30 amène une palette de briques, le plateau 32 revient dans une position angulaire de départ qui est toujours la même. Dès que la palette est déposée sur le plateau, celui-ci tourne pour occuper une position angulaire correspondant à celle de la plate-forme 16, avant que la palette ne soit levée par les câbles de levage. Une autre possibilité consiste à maintenir le plateau 32 dans une position de chargement et de le tourner, en cas de besoin, dans la position voulue. Ceci permet au chariot 30 d'amener toujours les palettes suivant la même direction et de remonter les palettes, malgré cela, suivant l'orientation correcte correspon­dant à l'emplacement sur la plate-forme 16.The brick pallets, two of which are on the platform 16 and are identified by the references 26 and 28 are brought, for example, using a forklift 30 vertically below the platform. form 16. According to one of the characteristics of the invention, they are deposited there on a rotary plate 32. This plate 32 can rotate, via an appropriate suspension, for example with rollers, around the axis 0 and this rotation is coordinated with that of the plate 16. The latter must, in fact, be able to rotate around the axis 0 so that the depalletization and brick-laying robot, represented by the reference 34, can reach the entire periphery of the converter. For example, each time the robot has completed a sector, the platform 16 is advanced by a certain angle, for example by 60 ° so that the robot can make the next sector. The plate 32 is rotated at the same time as the platform 16 by the same angle, but, when the carriage 30 brings a pallet of bricks, the plate 32 returns to an angular starting position which is always the same. As soon as the pallet is placed on the platform, it rotates to occupy an angular position corresponding to that of the platform 16, before the pallet is lifted by the lifting cables. Another possibility is to hold the plate 32 in a loading position and turn it, if necessary, to the desired position. This allows the carriage 30 to always bring the pallets in the same direction and to reassemble the pallets, despite this, in the correct orientation corresponding to the location on the platform 16.

Selon l'une des caractéristiques de la présente invention, les palettes sont remontées sur la plate-forme à l'aide d'une cage porte-palettes 36 et d'un panier 38 représentés en perspective sur la figure 3. La cage 36 est essentiellement constituée de deux parois latérales 40, 42 reliées entre elles par trois tablettes rectan­gulaires superposées 44, 46 et 48 et munies de quatre pieds 50 identiques l'un à l'autre. Le compartiment inférieur délimité par la tablette inférieure 44, la tablette intermédiaire 46 et les deux parois latérales 40 et 42 est destiné à recevoir une palette chargée de briques 54. Le compartiment supérieur se trouvant entre la tablette intermédiaire 46 et la tablette supérieure 48 est réservé aux palettes vides 56. Etant donné que le côté frontal et le côté dorsal de la cage sont ouverts, les palettes vides et pleines peuvent être introduites et extraites indifféremment par un côté ou l'autre de la cage , c'est-à-dire que celles-ci se présentent de la même manière vue de dos ou de face.According to one of the characteristics of the present invention, the pallets are raised on the platform using a pallet carrier cage 36 and a basket 38 shown in perspective in FIG. 3. The cage 36 is essentially consisting of two side walls 40, 42 connected together by three superimposed rectangular shelves 44, 46 and 48 and provided with four feet 50 identical to each other. The lower compartment delimited by the lower shelf 44, the intermediate shelf 46 and the two side walls 40 and 42 is intended to receive a pallet loaded with bricks 54. The upper compartment being between the intermediate shelf 46 and the upper shelf 48 is reserved for empty pallets 56. Since the front side and the dorsal side of the cage are open, the empty and full pallets can be inserted and extracted either from one side or the other of the cage, that is to say that they are presented in the same way seen from the back or from the front.

La profondeur de la cage 36 est égale à la largeur des palettes 52 et des briques 54, de sorte que l'alignement des briques sur les faces dorsales et frontales de la cage 36 constitue une assurance du positionnement correct des briques 54 sur une palette 52 et de celle-ci par rapport à la cage 36.The depth of the cage 36 is equal to the width of the pallets 52 and of the bricks 54, so that the alignment of the bricks on the dorsal and front faces of the cage 36 constitutes an assurance of the correct positioning of the bricks 54 on a pallet 52 and of this with respect to the cage 36.

La tablette supérieure 48 constitue , en outre, le fond d'un bac 58 entouré par des parois latérales dépassantes 40 et 42 et des bords longitudinaux sur le côté frontal et le côté dorsal reliant les bords formés par les parois latérales 40, 42. Ce bac 58 sert à recevoir les briques non utilisables , comme, par exemple, les briques cassées ou fendues et permet de profiter de la descente des palettes vides pour évacuer ce type de briques 58 de la plate-forme de travail.The upper shelf 48 constitutes, in addition, the bottom of a tank 58 surrounded by protruding side walls 40 and 42 and longitudinal edges on the front side and the dorsal side connecting the edges formed by the side walls 40, 42. This bin 58 is used to receive unusable bricks, such as, for example, broken or split bricks and makes it possible to take advantage of the descent of empty pallets to evacuate this type of bricks 58 from the working platform.

Le panier 38 est constitué essentiellement d'un tablier rectangulaire 60 dont la surface correspond sensiblement à la section horizontale de la cage 36 et qui est pourvu de deux panneaux longitudinaux rectangulaires 62, 64 dressés verti­calement sur le tablier 60 et de deux anses laté­rales 66, 68 pourvues d'ouvertures pour l'accrochage des câbles de levage. Le tablier 60 comporte, en outre, aux quatre coins des découpes 70 dont les formes et emplacements correspondent respectivement aux sections et emplacements des pieds 50 de la cage 36 de sorte que la cage 36 et le panier 38 puissent être emboîtés verticalement l'un dans l'autre comme représenté sur la figure 2.The basket 38 consists essentially of a rectangular apron 60 whose surface corresponds substantially to the horizontal section of the cage 36 and which is provided with two rectangular longitudinal panels 62, 64 erected vertically on the apron 60 and two lateral handles 66, 68 provided with openings for hanging the lifting cables. The apron 60 further comprises, at the four corners of the cutouts 70 whose shapes and locations correspond respectively to the sections and locations of the feet 50 of the cage 36 so that the cage 36 and the basket 38 can be fitted vertically one in the other as shown in Figure 2.

Les panneaux latéraux 62 et 64 du panier 38 ont une hauteur suffisante pour qu'ils ferment complètement le compartiment inférieur et au moins partiellement le compartiment supérieur de la cage 36 lorsque celle-ci est portée par le panier 38 comme montré sur la figure 2. Cette disposition présente plusieurs avantages. D'abord, les briques 54 sont bien maintenues en place, ce qui est important pour leur positionnement correct en vue de la dépalettisation automatique sur la plate-­forme. En plus , ni les briques, ni les palettes ne peuvant glisser hors de la cage 36 et provoquer des risques d'accident lors de leur chute.The side panels 62 and 64 of the basket 38 have a sufficient height so that they completely close the lower compartment and at least partially the upper compartment of the cage 36 when the latter is carried by the basket 38 as shown in FIG. 2. This arrangement has several advantages. First, the bricks 54 are well held in place, which is important for their correct positioning for automatic depalletization on the platform. In addition, neither the bricks nor the pallets can slip out of the cage 36 and cause the risk of accident during their fall.

En outre, si une brique 54 n'était pas positionnée correctement, ou que les palettes n'étaient pas correctement engagées dans leur com­partiment respectif, il serait impossible d'engager le panier 38 sur la cage 36 ou vice-versa. Autrement dit, le fait de pouvoir engager le panier 38 sur la cage 36 comme montré sur la figure 2, constitue une assurance que les briques 54 sont correctement positionnées.In addition, if a brick 54 was not positioned correctly, or if the pallets were not correctly engaged in their respective compartment, it would be impossible to engage the basket 38 on the cage 36 or vice versa. In other words, the fact of being able to engage the basket 38 on the cage 36 as shown in FIG. 2, constitutes an assurance that the bricks 54 are correctly positioned.

Les anses 66 , 68 du panier 38 sont suffi­samment hautes et s'étendent , de préférence, jusque dans la région de la tablette intermédiaire 46 de la cage 36 , afin que le centre de gravité de l'ensemble formé par la cage 36 et le panier 38 se trouve à un niveau inférieur à celui de l'accrochage du panier 38 aux câbles de levage afin d'améliorer la stabilité du chargement.The handles 66, 68 of the basket 38 are sufficiently high and preferably extend as far as the region of the intermediate shelf 46 of the cage 36, so that the center of gravity of the assembly formed by the cage 36 and the basket 38 is at a lower level than the attachment of basket 38 to the lifting cables in order to improve the stability of the load.

Le système de levage est arrangé, selon une autre caractéristique de l'invention, en-dessous de la plate-forme 16 dans un boîter 72. Aussi bien le fond du boîtier 72 que la plate-forme 16 comportent une ouverture rectangulaire centrale 74 respective­ment 76 permettant le passage de la cage porte-­palettes 36. La montée des palettes sur la plate-­ forme 16 est réalisée en deux étapes. Un premier système de levage sert à remonter, à l'aide d'une paire de câbles 78 , 80 accrochés aux anses du panier 38, la cage 36 jusque dans le boîtier 72 . Les câbles 78 et 80 évoluent autour d'une série de poulies de guidage et de renvoi montées sous la plate-­forme 16 autour de l'ouverture 76 et sont enroulées sur une paire de treuils 82, 84, l'un étant visible sur la figure 1, l'autre sur la figure 2. Ces treuils 82, 84, sont installés sur le fond du boîtier 72 de part et d'autre de l'ouverture 74. Pour assurer une remontée horizontale de la cage 36, il est bien entendu nécessaire que l'opération des treuils 82 et 84 soit parfaitement synchronisée.According to another characteristic of the invention, the lifting system is arranged below the platform 16 in a box 72. Both the bottom of the box 72 and the platform 16 have a central rectangular opening 74 respectively 76 allowing the passage of the pallet carrier cage 36. The mounting of the pallets on the platform form 16 is carried out in two stages. A first lifting system is used to raise, by means of a pair of cables 78, 80 hooked to the handles of the basket 38, the cage 36 as far as the housing 72. The cables 78 and 80 evolve around a series of guide and return pulleys mounted under the platform 16 around the opening 76 and are wound on a pair of winches 82, 84, one being visible on the Figure 1, the other in Figure 2. These winches 82, 84, are installed on the bottom of the housing 72 on either side of the opening 74. To ensure a horizontal rise of the cage 36, it is good understood that the operation of winches 82 and 84 must be perfectly synchronized.

Pour faciliter la synchronisation de la montée des deux câbles 78, 80, il est également possible de les enrouler sur un seul et unique treuil divisé en deux parties axiales.To facilitate synchronization of the rise of the two cables 78, 80, it is also possible to wind them on a single winch divided into two axial parts.

Le ou les treuils d'enroulement des câbles 78, 80 comportent des moyens non représentés , mais connus en soi, pour ralentir la vitesse de montée lorsque la cage 36 pénètre dans le boîtier 72 et ceci progressivement au fur et à mesure qu'elle s'approche du niveau de la plate-forme 16.The cable winding winch or winches 78, 80 include means, not shown, but known per se, for slowing the rate of climb when the cage 36 enters the housing 72 and this progressively as it s approach to platform level 16.

Cette fin de course de la cage 36 est illustrée sur les figures 4a et 4b . A partir du moment où la cage 36 pénètre dans le boîtier 72 comme représenté sur la figure 4a, sa vitesse est réduite progressivement jusqu'au moment où elle arrive dans la position de la figure 4b. L'arrêt des treuils est déterminé et commandé automatiquement par des détecteurs de fin de course représentés schématiquement par la référence 86 et montés sur les bords de l'ouverture 76 dans la plate-forme 16. Ces détecteurs 86 sont actionnés par des doigts 88 prévus aux endroits correspondants des panneaux latéraux du panier 38. Ces détecteurs 86 peuvent être constitués par des palpeurs électromécaniques bien connus en soi ou d'autres palpeurs connus. Il est préférable de prévoir deux doigts 88 sur chacun des panneaux 62, 64 du panier 38 et quatre détecteurs corres­pondants 86. Ces détecteurs 86 sont, de préférence, montés dans un circuit de contrôle qui déclenche un signal lorsque tous les détecteurs ne sont pas actionnés simultanément. En effet, un déclenchement de l'un des détecteurs seulement signifie que le panier 38 n'est pas horizontal et qu'une vérification s'impose. Les détecteurs 86 sont avantageusement associés à des amortisseurs, par exemple à ressort 90 comme montré sur les figures ou des amortisseurs hydrauliques ou pneumatiques connus en soi pour assurer un arrêt progressif et absorber l'inertie de la cage 36.This end of travel of the cage 36 is illustrated in FIGS. 4a and 4b. From the moment the cage 36 enters the housing 72 as shown in FIG. 4a, its speed is gradually reduced until it arrives in the position of FIG. 4b. The stopping of the winches is determined and controlled automatically by end-of-travel detectors represented schematically by the reference 86 and mounted on the edges of the opening 76 in the platform 16. These detectors 86 are actuated by fingers 88 provided at the corresponding locations of the side panels of the basket 38. These detectors 86 can be constituted by electromechanical sensors well known per se or other known sensors. It is preferable to provide two fingers 88 on each of the panels 62, 64 of the basket 38 and four corresponding detectors 86. These detectors 86 are preferably mounted in a control circuit which triggers a signal when all the detectors are not actuated simultaneously. Indeed, a triggering of only one of the detectors means that the basket 38 is not horizontal and that a check is necessary. The detectors 86 are advantageously associated with dampers, for example with spring 90 as shown in the figures, or hydraulic or pneumatic dampers known per se to ensure progressive stopping and absorb the inertia of the cage 36.

Quel que soit le nombre de détecteurs, et même si le panier 38 n'est pas horizontal, dès que l'un d'entre eux est actionné, les deux treuils 82, 84 sont arrêtés automatiquement, laissant la cage 36 dans la position d'attente illustrée sur la figure 4b.Whatever the number of detectors, and even if the basket 38 is not horizontal, as soon as one of them is actuated, the two winches 82, 84 are stopped automatically, leaving the cage 36 in the position d expectation illustrated in Figure 4b.

Un deuxième système de levage sert à hisser la cage 36 de la position d'attente jusque dans la position de la figure 4c pour amener la palette se trouvant dans le compartiment inférieur de la cage 36 au niveau de la plate-forme 16.A second lifting system is used to hoist the cage 36 from the standby position to the position in FIG. 4c to bring the pallet located in the lower compartment of the cage 36 to the level of the platform 16.

Ce deuxième dispositif de levage comporte deux vérins 92, 94 hydrauliques ou des moteurs montés sous la plate-forme 16 dans le boîtier 72 de part et d'autre des ouvertures 74 et 76 . Comme il ressort plus claire­ment de la figure 2, la tige des vérins 92, 94, qui est, de préférence, téléscopique , porte une paire de poulies 96 autour desquelles passent deux câbles ou chaînes 98, 100 fixés par l'une de leurs extrémités au boîtier 72 ou au vérin 92, 94 et par l'autre extrémité à une traverse 102 déplaçable verticalement entre une paire de rails latéraux 104, 106.This second lifting device comprises two hydraulic cylinders 92, 94 or motors mounted under the platform 16 in the housing 72 on either side of the openings 74 and 76. As is clearer from FIG. 2, the rod of the cylinders 92, 94, which is preferably telescopic, carries a pair of pulleys 96 around which pass two cables or chains 98, 100 fixed by one of their ends to the housing 72 or to the jack 92, 94 and by the other end to a cross member 102 vertically movable between a pair of lateral rails 104, 106.

Le vérin opposé 94, seulement visible sur les figures 4, agit, de la même manière que le vérin 92, par l'intermédiaire de deux poulies et de deux câbles sur une traverse 108 déplaçable verticalement entre deux rails latéraux.The opposite cylinder 94, only visible on the Figures 4, acts, in the same way as the cylinder 92, by means of two pulleys and two cables on a cross member 108 movable vertically between two side rails.

La mise en service des vérins 92, 94 , qui doivent, bien entendu, être opérés en même temps et de façon synchronisée, fait remonter les traverses 102 et 108 le long de leur rail respectif. Le trajet parcouru par les traverses 102 et 108 est le double de celui des tiges des vérins 92 et 94 à cause du renvoi des câbles par dessus les poulies.The commissioning of the cylinders 92, 94, which must, of course, be operated at the same time and in a synchronized manner, causes the cross members 102 and 108 to go up along their respective rail. The path traveled by the cross members 102 and 108 is twice that of the rods of the cylinders 92 and 94 because of the return of the cables over the pulleys.

Chacune des traverses 102, 108 comporte une paire de crics 110, 114 respectivement 116, 118. Ces crics sont montés aux extrémités des traverses, sous forme de cliquets pivotants de manière à se trouver, en position opérative, sur la trajectoire des pieds 50 de la cage 36. En position inopérative des traverses 104, 108, c'est-à-­dire en position basse, ces crics pivotent dans une position inopérative sous l'action d'un rebord remontant 74a autour de l'ouverture 74 du boîtier 72 (voir figure 4a). Dès que les traverses 102, 108 remontent sous l'action des vérins 92, 94, ils pivotent, libérés de l'action du rebord 74a, dans une position horizontale sous l'action de leur propre poids ( voir figure 4b ) ou d'une commande appropriée, par exemple d'un ressort.Each of the crosspieces 102, 108 comprises a pair of jacks 110, 114 respectively 116, 118. These jacks are mounted at the ends of the crosspieces, in the form of pivoting pawls so as to be, in the operative position, on the path of the feet 50 of the cage 36. In the inoperative position of the crosspieces 104, 108, that is to say in the low position, these jacks pivot in an inoperative position under the action of a rising edge 74a around the opening 74 of the housing 72 (see figure 4a). As soon as the crosspieces 102, 108 rise under the action of the cylinders 92, 94, they pivot, released from the action of the flange 74a, in a horizontal position under the action of their own weight (see FIG. 4b) or an appropriate control, for example a spring.

Lorsque la cage 36 a atteint la position d'attente illustrée à la figure 4b sous l'action du premier dispo­sitif de levage, le second dispositif de levage est immédiatement actionné pour remonter les crics 110, 114, 116, 118 dans la position de support des pieds de la cage 36 illustrée sur la figure 4b. Ceci constitue une mesure de précaution étant donné que la cage 36 peut demeurer un certain temps dans cette position en attendant la dépalettisation d'une palette sur la plate-forme 16.When the cage 36 has reached the waiting position illustrated in FIG. 4b under the action of the first lifting device, the second lifting device is immediately actuated to raise the jacks 110, 114, 116, 118 into the support position of the feet of the cage 36 illustrated in FIG. 4b. This constitutes a precautionary measure since the cage 36 can remain in this position for a certain time while awaiting the depalletization of a pallet on the platform 16.

La poursuite de l'action des vérins 92, 94 permet de hisser la cage 36 de la position illustrée sur la figure 4b vers la position illustrée sur la figure 4 c à partir de laquelle il est possible d'extraire la palette chargée 52. Il est à noter que, lors de l'action du second dispositif de levage, la cage 36 est sortie de son panier 38, celui-ci demeu­rant dans la position d'attente, accroché aux câbles 78, 80 du premier dispositif de levage.The continued action of the cylinders 92, 94 makes it possible to hoist the cage 36 from the position illustrated in FIG. 4b to the position illustrated in the FIG. 4 c from which it is possible to extract the loaded pallet 52. It should be noted that, during the action of the second lifting device, the cage 36 has come out of its basket 38, the latter remaining in the standby position, hooked to the cables 78, 80 of the first lifting device.

Sur la plate-forme 16 se trouvent deux chariots 120, 122 évoluant , par l'intermédiaire de galets , sur deux rails latéraux 124, 126. Chaque chariot comporte une fourche 128 pouvant être engagée sous une palette ( voir figure 1 ). Après que la cage 36 avec une palette chargée 52 ait été hissée au niveau de la figure 4c, celui des deux chariots 120, 122 qui est vide est déplacé automatiquement, ou sur commande, au-dessus de l'ouverture 76 de manière que sa fourche 128 pénètre sous la palette 52. Lorsque sa fourche 128 est complètement engagée sous la palette 52, le second dispositif de levage est relâché légèrement jusqu'à ce que la palette 52 soit supportée par la fourche 128 et ne prenne plus appui sur la tablette inférieure 44 de la cage 36. Dès lors, le chariot 120 ou122 est à nouveau déplacé vers sa position initiale emmenant avec lui la palette hors de la cage 36.On the platform 16 are two carriages 120, 122 moving, by means of rollers, on two lateral rails 124, 126. Each carriage has a fork 128 which can be engaged under a pallet (see FIG. 1). After the cage 36 with a loaded pallet 52 has been hoisted at the level of FIG. 4c, that of the two carriages 120, 122 which is empty is moved automatically, or on command, above the opening 76 so that its fork 128 enters under the pallet 52. When its fork 128 is fully engaged under the pallet 52, the second lifting device is released slightly until the pallet 52 is supported by the fork 128 and no longer bears on the shelf lower 44 of the cage 36. Consequently, the carriage 120 or 122 is again moved to its initial position taking with it the pallet out of the cage 36.

Chacun des chariots 120, 122 est associé à deux détecteurs de position 130 et 132 destinés à contrôler la position latérale et la position longi­tudinale de la palette et de ses briques . Ces détecteurs , qui peuvent être des détecteurs méca­niques ou des détecteurs à rayons , servent à contrôler si la position de la palette est correcte et conforme au programme du robot 34 et servent , le cas échéant, à commander une correction de position des chariots 120, 122 et/ou de la monoeuvre du robot.Each of the carriages 120, 122 is associated with two position detectors 130 and 132 intended to control the lateral position and the longitudinal position of the pallet and its bricks. These detectors, which can be mechanical detectors or ray detectors, serve to check whether the position of the pallet is correct and in accordance with the program of the robot 34 and serve, if necessary, to order a correction of the position of the carriages 120, 122 and / or the robot's operation.

Sur les figures 1 et 2 , on reconnaît , en outre, une cabine de commande 134 permettant à un opérateur de contrôler , sous abri, les différentes opérations se déroulant automatiquement sur la plate-­forme 16 et d'intervenir éventuellement en cas de besoin. Cette cabine peut être climatisée pour offrir des conditions de travail optimales.In FIGS. 1 and 2, it is further recognized that a control cabin 134 allows an operator to control, under shelter, the various operations taking place automatically on platform 16 and to intervene if necessary. This cabin can be air conditioned to provide optimal working conditions.

Le fonctionnement de l'installation ressort de sa description et ne sera commenté que brièvement ci-­dessous. Lorsque la cage 36 est descendue de la plate-­forme 16 avec une palette vide, le plateau 32 est orienté de manière à correspondre à la position angu­laire de la plate-forme 16 pour recevoir le panier 38 et la cage 36. Le plateau 32 est tourné dans sa position de départ pour dégager la palette vide 56 et remettre immédiatement une palette pleine 52 dans le compartiment inférieur de la cage 36. Après rotation du plateau 32 vers la position angulaire correspondant à celle de la plate-forme 16, le panier 38 et la cage porte-palettes 36 sont remontés jusque dans la position d'attente selon la figure 4b. L'ensemble demeure dans cette position d'attente, accroché aux câbles 78 et 80 et reposant par les pieds 50 sur les crics 110, 114, 116, 118 jusqu'à ce que l'une des deux palettes 26, 28 qui est à remplacer soit vide.The operation of the installation is apparent from its description and will only be briefly commented on below. When the cage 36 is lowered from the platform 16 with an empty pallet, the plate 32 is oriented so as to correspond to the angular position of the platform 16 to receive the basket 38 and the cage 36. The plate 32 is turned to its starting position to disengage the empty pallet 56 and immediately return a full pallet 52 to the lower compartment of the cage 36. After rotation of the plate 32 towards the angular position corresponding to that of the platform 16, the basket 38 and the pallet carrier cage 36 are raised to the standby position according to FIG. 4b. The assembly remains in this waiting position, hooked to the cables 78 and 80 and resting by the feet 50 on the jacks 110, 114, 116, 118 until one of the two pallets 26, 28 which is at replace either empty.

Le fait d'amener, dès que possible, la cage 36 dans la position d'attente de la figure 4b, présente plusieurs avantages. Le changement de palette peut s'effectuer immédiatement, dès que la palette à changer est vide, de sorte que la perte de temps est minimale.Bringing the cage 36 as soon as possible into the waiting position of FIG. 4b has several advantages. The pallet change can be carried out immediately, as soon as the pallet to be changed is empty, so that the loss of time is minimal.

Tout le temps que la cage 36 occupe la position d'attente, l'ouverture 76 est automatiquement bouchée, de sorte qu'un danger d'accident est réduit. Ensuite, toutes les briques 58 ne pouvant être uti­lisées, quelle qu'en soit la raison, peuvent être déposées dans le bac 48 de la cage 36 de sorte qu'on peut profiter au maximum de l'espace disponible sur la plate-forme 16.While the cage 36 occupies the standby position, the opening 76 is automatically blocked, so that an accident hazard is reduced. Then, all the bricks 58 that cannot be used, for whatever reason, can be placed in the bin 48 of the cage 36 so that we can make the most of the space available on the platform 16 .

Dès que la palette 26 ou 28 à changer est vide, ou est entrain d'être vidée , la cage 36 est hissée par les crics 110, 114, 116, 118 hors du panier 36 dans une position intermédiaire entre celle des figures 4b et 4c dans laquelle le compar­timent supérieur de la cage 36 se trouve au niveau de la plate-forme 16. Celui des chariots 120 ou 122 portant la palette vide est ensuite actionné pour venir la déposer dans le compartiment supérieur de la cage 36. Après le retrait du chariot de ce compartiment supérieur, la cage 36 est hissée jusqu'au niveau de la figure 4c et dans cette posi­tion , la palette pleine 52 peut être dégagée comme décrit ci-dessus.As soon as the pallet 26 or 28 to be changed is empty, or is being emptied, the cage 36 is hoisted by the jacks 110, 114, 116, 118 out of the basket 36 in an intermediate position between that of FIGS. 4b and 4c in which the upper compartment of the cage 36 is located at the level of the platform 16. That of the carriages 120 or 122 carrying the empty pallet is then actuated to come and deposit it in the upper compartment of the cage 36. After removing the carriage of this upper compartment, the cage 36 is hoisted up to the level of FIG. 4c and in this position, the full pallet 52 can be released as described above.

Les opérations de chargement de la palette vide 56 ou de déchargement de la palette pleine 52 peuvent être réalisées automatiquement ou sur commande de l'opérateur se trouvant dans la cabine de commande 134.The operations of loading the empty pallet 56 or unloading the full pallet 52 can be carried out automatically or on command of the operator located in the control cabin 134.

Dès que la palette pleine 52 est extraite de la cage 36 , celle-ci est à nouveau descendue dans son panier 36 par la descente des crics 110, 114, 116 , 118. A partir de la position représentée sur la figure 4b, la cage 36 est prise en charge par les câbles 78, 80 du premier dispositif de levage, alors que les crics sont descendus dans la position de la figure 4a pour être cabrés sous l'action du rebord 74a et permettre le passage du panier 38 et de la cage 36 qui sont descendus immédiatement après par le déroulement des câbles 78 et 80.As soon as the full pallet 52 is extracted from the cage 36, the latter is again lowered into its basket 36 by the descent of the jacks 110, 114, 116, 118. From the position shown in FIG. 4b, the cage 36 is supported by the cables 78, 80 of the first lifting device, while the jacks are lowered into the position of FIG. 4a to be rearing up under the action of the flange 74a and allowing the basket 38 and the cage 36 which are lowered immediately afterwards by the unwinding of cables 78 and 80.

Il reste à noter que quoique décrite en référence à une plate-forme portée avec chargement des palettes par le bas, l'invention s'applique également à des plate-formes suspendues avec chargement des palettes par le haut.It should be noted that although described with reference to a platform carried with loading of pallets from the bottom, the invention also applies to suspended platforms with loading of pallets from the top.
