Description

La présente invention concerne un transtockeur et un système de stockage de charges utilisant un tel transtockeur.
Les transtockeurs sont des appareils utilisés notamment dans la manutention de charges à l'intérieur de magasins comportant des rayonnages et des allées de circulation rectilignes.The present invention relates to a stacker crane and a load storage system using such a stacker crane.
Stacker cranes are devices used in particular for handling loads inside stores with shelving and straight aisles.

Le document FR-A-2 266 655 décrit un pont-gerbeur télescopique, notamment pour cales qui comporte une colonne télescopique formée de quatre éléments 1, 2, 3, 4 et un organe de manutension 5. La colonne est montée sur le chariot 9 d'un pont roulant 28 par l'intermédiaire d'une plateforme pivotante 6, le chariot 9 circulant au moyen de roues sur des chemins de roulement du pont 28.The document FR-A-2 266 655 describes a telescopic stacker, especially for wedges which comprises a telescopic column formed by four elements 1, 2, 3, 4 and a handling member 5. The column is mounted on the carriage 9 of an overhead crane 28 via a pivoting platform 6, the carriage 9 circulating by means of wheels on the tracks of the bridge 28.

Le déplacement des différents éléments de la colonne télescopique est effectué au moyen de chaîne 16 et 17 pour les éléments 1 et 2 puis de câbles en acier 18 et 19 pour l'élément 3, enfin l'élément 4 coulisse sur la plateforme 6 par le moyen de chaînes de galle 7 et l'organe de manutention 5 coulisse le long de l'élément 1 par des câbles en acier 13. La montée et la descente de l'élément 4 se fait par un premier treuil 8, celui de l'organe de manutention 5 par un tambour 12 et les éléments 1, 2 et 3 par un élément de commande 20 à tambour.The different elements of the telescopic column are moved by means of chain 16 and 17 for elements 1 and 2, then steel cables 18 and 19 for element 3, finally element 4 slides on the platform 6 by the means of gall chains 7 and the handling member 5 slides along the element 1 by steel cables 13. The ascent and descent of the element 4 is done by a first winch 8, that of the handling member 5 by a drum 12 and the elements 1, 2 and 3 by a drum control element 20.

La présente invention a pour but de proposer un transtockeur comportant un mât télescopique à mécanisme beaucoup plus simple et assurant un mouvement simultané de tout les ensembles mobiles et sans aucun à-coup pour la charge. L'invention permet aussi d'assurer une entrée et une sortie de charges à un niveau plus élevé et de diminuer le volume du magasin.The object of the present invention is to propose a stacker crane comprising a telescopic mast with a much simpler mechanism and ensuring simultaneous movement of all the mobile assemblies and without any jerk for the load. The invention also makes it possible to ensure the entry and exit of loads at a higher level and to reduce the volume of the store.

L'invention a ainsi pour objet un transtockeur comportant au moins un mât vertical et un plateau élévateur, le mât étant monté sur un châssis muni de galets de roulement pour son déplacement le long de deux rails guides parallèles, ledit mât, ou chaque mât, étant télescopique et comprenant au moins deux éléments mobiles les uns par rapport aux autres, le premier élément étant directement lié audit châssis et le dernier élément portant ledit plateau monté coulissant le long de ce dernier élément, caractérisé en ce que le mouvement de coulissement du plateau le long du dernier élément et des divers éléments entre eux est effectué au moyen d'une chaîne, unique par mât, ayant un point lié au plateau et passant sur au moins un pignon situé au voisinage de chaque extrémité de chaque élément, le pignon situé au voisinage de l'extrémité inférieure de chaque élément autre que le premier, constituant le pignon de sortie d'un réducteur, lié audit élément, dont le pignon d'entrée est entraîné en rotation par le brin de chaîne situé entre le pignon supérieur et le pignon inférieur de l'élément précédent et en ce qu'un moteur d'entraînement, monté sur ledit châssis, entraîne en rotation un pignon moteur d'entraînement de ladite chaîne.The subject of the invention is therefore a stacker crane comprising at least one vertical mast and a lifting platform, the mast being mounted on a chassis provided with rollers for its movement along two parallel guide rails, said mast, or each mast, being telescopic and comprising at least two elements movable with respect to each other, the first element being directly connected to said chassis and the last element carrying said plate mounted to slide along this last element, characterized in that the sliding movement of the plate along the last element and the various elements between them is effected by means of a chain, unique per mast, having a point linked to the plate and passing over at least one pinion situated in the vicinity of each end of each element, the pinion situated in the vicinity of the lower end of each element other than the first, constituting the output pinion of a reduction gear, linked to said element, the input pinion of which is driven in rotation by the chain strand located between the upper sprocket and the lower sprocket of the preceding element and in that a drive motor, mounted on said chassis, rotates a drive sprocket driving said chain.

Selon une autre caractéristique, les rapports de réduction des réducteurs sont tels que le coulissement dudit plateau le long dudit dernier élément ainsi que le déploiement télescopique des divers éléments commencent et se terminent simultanément.According to another characteristic, the reduction ratios of the reducers are such that the sliding of said plate along said last element as well as the telescopic deployment of the various elements begin and end simultaneously.

Selon une réalisation préférée de l'invention, le mât est composé de deux éléments.According to a preferred embodiment of the invention, the mast is composed of two elements.

L'invention a aussi pour objet un système de stockage de charges dans un magasin à rayonnages au moyen d'un transtockeur tel que ci-dessus, caractérisé par le fait que le magasin comporte une ouverture dans son plafond par laquelle ledit transtockeur extrait et/ou introduit lesdites charges.The invention also relates to a load storage system in a racking store by means of a stacker crane as above, characterized in that the store has an opening in its ceiling through which said stacker crane extracts and / or introduces said charges.

L'invention trouve une application particulièrement bien adaptée dans le stationnement des véhicules automobiles. Dans cette application, ledit magasin est un parc souterrain de stationnement communiquant avec la surface par un puits.The invention finds a particularly suitable application in the parking of motor vehicles. In this application, said store is an underground car park communicating with the surface by a well.

L'invention va maintenant être décrite en référence au dessin annexé dans lequel :The invention will now be described with reference to the accompanying drawing in which:

La figure 1 montre schématiquement un transtockeur selon l'invention.Figure 1 schematically shows a stacker crane according to the invention.

Les figures 2, 3 et 4 montrent selon trois vues un magasin de stockage de charges à entrées et sorties par le plafond.Figures 2, 3 and 4 show according to three views a store of load storage with inputs and outputs by the ceiling.

En se référant à la figure 1, on voit un transtockeur qui est composé d'un mât vertical 1. Selon le cas, notamment le poids des charges, il peut y avoir non pas un seul mât mais deux mâts disposés parallèlement, mais ceci ne change en rien le principe de l'invention qui est indépendant du nombre de mâts.Referring to Figure 1, we see a stacker crane which is composed of a vertical mast 1. Depending on the case, in particular the weight of the loads, there may not be a single mast but two masts arranged in parallel, but this does not change the principle of the invention which is independent of the number of masts.

Le mât vertical 1 est monté sur un châssis 2 muni de galets de roulements 3, pour le déplacement de l'ensemble le long de deux rails parallèles 4. Qu'il y ait un ou plusieurs mâts, le châssis roule le long de deux rails guides.The vertical mast 1 is mounted on a chassis 2 provided with roller rollers 3, for moving the assembly along two parallel rails 4. Whether there is one or more masts, the chassis rolls along two rails guides.

Le mât 1 est télescopique et comprend, dans l'exemple représenté, deux éléments : le premier 5 et le dernier 6 qui est dans le cas de l'exemple le deuxième et dernier. Il pourrait bien entendu y avoir plus de deux éléments, mais la chaîne cinématique s'en trouverait compliquée. Le dernier élément 6 est monté coulissant le long du premier élément 5 qui lui est fixe et lié directement au châssis 2. Un plateau 7 porteur de charges 8 est monté coulissant le long du deuxième et dernier élément 6.The mast 1 is telescopic and comprises, in the example shown, two elements: the first 5 and the last 6 which is in the case of the example the second and last. There could of course be more than two elements, but the kinematic chain would be complicated. The last element 6 is mounted to slide along the first element 5 which is fixed to it and connected directly to the chassis 2. A plate 7 carrying loads 8 is mounted to slide along the second and last element 6.

Une chaîne 9 assure le mouvement de coulissement du plateau 7 le long de l'élément 6 et de l'élément 6 le long du premier élément 5. Cette chaîne 9 est liée au plateau 7 au point 10 et elle passe sur au moins un pignon situé au voisinage de chaque extrémité de chaque élément : un pignon supérieur 11 et un pignon inférieur 12 pour le second élément 6, deux pignons supérieurs 13 et deux pignons inférieurs 14 pour le premier élément 5. La chaîne est en outre entraînée en mouvement par l'intermédiaire d'un pignon moteur 15 entraîné en rotation par un moteur d'entraînement 16 monté sur le châssis 2. Un contre pignon 17 assure en outre la bonne application de la chaîne sur les pignons 14 et 15.A chain 9 ensures the sliding movement of the plate 7 along the element 6 and of the element 6 along the first element 5. This chain 9 is linked to the plate 7 at point 10 and it passes over at least one pinion located near each end of each element: an upper pinion 11 and a lower pinion 12 for the second element 6, two upper pinions 13 and two lower pinions 14 for the first element 5. The chain is also driven in motion by the by means of a motor pinion 15 driven in rotation by a drive motor 16 mounted on the chassis 2. A counter pinion 17 also ensures the correct application of the chain on the pinions 14 and 15.

Afin que le plateau 7 commence à coulisser le long du second élément 6 en même temps que commence le coulissement du second élément 6 le long du premier élément 5, le pignon inférieur 12 du second élément 6 constitue le pignon de sortie d'un réducteur 18, solidaire de l'élément 6, dont le pignon d'entrée 19 est entraîné en rotation par le brin de la chaîne située entre les pignons supérieurs 13 et inférieurs 14 du premier élément 5. Un galet ou pignon 20 permet d'appliquer la chaîne 9 contre le pignon d'entrée 19.So that the plate 7 begins to slide along the second element 6 at the same time as the sliding of the second element 6 begins along the first element 5, the lower pinion 12 of the second element 6 constitutes the output pinion of a reducer 18 , integral with the element 6, the input pinion 19 of which is rotated by the strand of the chain situated between the upper pinions 13 and lower 14 of the first element 5. A roller or pinion 20 makes it possible to apply the chain 9 against the input pinion 19.

En pointillé, on a représenté le plateau 7 et le second élément 6 en position basse.In dotted lines, there is shown the plate 7 and the second element 6 in the low position.

Si la course du plateau 7 le long du second élément 6 est égale à L₂ et si la course du second élément 6 le long du premier élément 5 est L₁ et que l'on souhaite que les deux coulissements commencent et se terminent simultanément, il faut que le rapport de réduction ρ entre le pignon de sortie 12 ( ρ ₁₂) et le pignon d'entrée 19 ( ρ ₁₉) soit tel que : ρ = ρ₁₂ ρ₁₉ = L₂ 2L₁ + L₂

Figure imgb0001
If the stroke of the plate 7 along the second element 6 is equal to L₂ and if the stroke of the second element 6 along the first element 5 is L₁ and it is desired that the two slides start and end simultaneously, it is necessary to that the reduction ratio ρ between the output pinion 12 (ρ ₁₂) and the input pinion 19 (ρ ₁₉) is such that: ρ = ρ₁₂ ρ₁₉ = Where 2L₁ + L₂
Figure imgb0001

Dans cette formule, le pignon d'entrée 19 et de sortie 12 ont le même nombre de dents.In this formula, the input pinion 19 and output pinion 12 have the same number of teeth.

Bien entendu, le mât télescopique 1 pourrait avoir plus de deux éléments et par exemple trois.Of course, the telescopic mast 1 could have more than two elements and for example three.

Dans ce cas, on aurait deux réducteurs : un premier R₁ entre le troisième élément et le second et un deuxième R₂ entre le second élément et le premier et les rapports ρ₁ et ρ₂ entre les pignons respectifs de sortie ρ S et d'entrée ρ e serait :

Figure imgb0002

avec

  • L₃ la course du plateau le long du troisième élément,
  • L₂ la course du troisième élément le long du second élément,
  • L₁ la course du second élément le long du premier élément.
In this case, there would be two reducers: a first R₁ between the third element and the second and a second R₂ between the second element and the first and the ratios ρ₁ and ρ₂ between the respective pinions of output ρ S and input ρ e would be :
Figure imgb0002
with
  • There the stroke of the plate along the third element,
  • Where the travel of the third element along the second element,
  • There the stroke of the second element along the first element.

Ce dispositif permet d'assurer la montée continue du plateau 7 sans aucun à-coup.This device ensures the continuous rise of the plate 7 without any jerk.

Une application particulièrement intéressante d'un tel transtockeur est le cas d'un magasin à rayonnage où les charges entrent et sortent par le plafond, la hauteur intérieure du magasin correspondant à la hauteur du premier élément fixe 5 du mât télescopique 1.A particularly advantageous application of such a stacker crane is the case of a racking store where the loads enter and exit through the ceiling, the interior height of the store corresponding to the height of the first fixed element 5 of the telescopic mast 1.

Les figures 2, 3 et 4 montrent une telle application où les charges 8 peuvent, dans un cas particulier très intéressant, être des véhicules automobiles et où le magasin 21 est alors un parc souterrain de stationnement. Dans ces figures, on voit ainsi un parc de stationnement souterrain 21 avec une allée centrale 22 le long de laquelle circule un transtockeur 23 du type télescopique tel que décrit ci-dessus et comportant ici deux mâts 1A et 1B. De part et d'autre de l'allée centrale sont situés des rayonnages 24.Figures 2, 3 and 4 show such an application where the loads 8 can, in a very interesting particular case, be motor vehicles and where the store 21 is then an underground parking lot. In these figures, we thus see an underground parking lot 21 with a central driveway 22 along which a stacker crane 23 of the telescopic type as described above and here comprising two masts 1A and 1B. On both sides of the central aisle are shelves 24.

A une extrémité de l'allée centrale 22 le plafond 25 du parc de stationnement est percé d'une ouverture 26 formant un puits 27 qui aboutit à la surface 28.At one end of the central aisle 22, the ceiling 25 of the parking lot is pierced with an opening 26 forming a well 27 which leads to the surface 28.

Un petit local 29 est bâtit autour du puits 27 et une porte de sécurité, non représentée, mais connue en soi, comme par exemple les portes d'ascenseurs, permet l'entrée d'un véhicule uniquement lorsque, sur demande de stationnement, le plateau 7 du transtockeur 23, se trouve à niveau.A small room 29 is built around the well 27 and a security door, not shown, but known per se, such as for example the elevator doors, allows the entry of a vehicle only when, on request for parking, the platform 7 of stacker crane 23, is level.

Le plateau 7 du transtockeur est équipé d'un organe extracteur transversal d'un type connu en soi pour pouvoir déposer et extraire les véhicules ou charges 8 des alvéoles de stationnement.The platform 7 of the stacker crane is equipped with a transverse extractor member of a type known per se in order to be able to deposit and extract the vehicles or loads 8 from the parking cells.
