Description

La présente invention concerne des appareils de transport de charges légères (10 à 15 kg) placées dans des conteneurs véhiculés par des chariots automoteurs sur rails.The present invention relates to light load transport devices (10 to 15 kg) placed in containers carried by self-propelled carriages on rails.

D'une manière générale, on sait que divers appareils de ce genre ont été déjà proposés.In general, we know that various devices of this kind have already been proposed.

Ainsi, dans un premier type d'appareils connu, notamment par le brevet US 4 015 537, les conteneurs sont fixés à demeure sur les chariots automoteurs.Thus, in a first type of device known, in particular from US Pat. No. 4,015,537, the containers are permanently fixed to the self-propelled carriages.

Dans ce cas, les chariots peuvent être équipés de curseurs mobiles mémorisant la station destinatrice. Pour que ces installations fonctionnent correctement, les stations doivent disposer en permanence d'un certain nombre de chariots qui leur sont préaffectés. Pour ce faire, les stations destinatrices doivent les retourner impérativement à la station expéditrice dans les meilleurs délais. Il s'agit là d'un inconvénient majeur aboutissant au blocage des installations si les règles d'exploitation ne sont pas respectées.In this case, the carriages can be equipped with mobile cursors memorizing the destination station. For these installations to function properly, the stations must have a certain number of carriages permanently allocated to them. To do this, the destination stations must imperatively return them to the sending station as soon as possible. This is a major drawback leading to the blocking of the installations if the operating rules are not respected.

Bien entendu, un pilotage par ordinateur des appareils de transport peut permettre la banalisation des chariots automoteurs. Dans ce cas, les stations ne disposent plus de chariots préaffectés. Ceux-ci stationnent dans des zones de parcage prévues à cet effet à divers endroits de l'installation. Une station désirant faire une expédition appelle un chariot automoteur avec conteneur vide et procède après son chargement à un envoi. La station destinatrice doit vider le chariot dans les délais les plus brefs et le renvoyer sur une zone de parcage de chariots avec conteneurs vides.Of course, computer control of the transport devices can allow the standardization of self-propelled carriages. In this case, the stations no longer have pre-assigned carriages. These are parked in parking areas provided for this purpose at various places in the installation. A station wishing to make a shipment calls a self-propelled cart with an empty container and proceeds after loading to a shipment. The destination station must empty the trolley as soon as possible and send it back to a trolley parking area with empty containers.

Ainsi, dans les deux types d'appareils précédemment évoqués, les stations destinatrices ne procédant pas aux renvois des chariots sont très vite saturées. Cette situation réduit les performances et aboutit rapidement au blocage de l'installation.Thus, in the two types of apparatus mentioned above, the destination stations which do not return the carriages are very quickly saturated. This situation reduces performance and quickly results in the installation freezing.

Un autre type d'appareils divulgué notamment par le brevet allemand DE 33 08 778 prévoit des conteneurs amovibles verrouillables sur les chariots automoteurs. Toutefois, l'inconvénient de cette solution réside en ce que pour que l'installation puisse fonctionner correctement, l'utilisateur doit être présent au moment où le chariot automoteur pénètre dans la station, soit pour le charger ou le décharger, et ce, de manière à ce qu'il puisse être rapidement réutilisé pour une autre mission. Pour supprimer cet inconvénient, le brevet GB 2 194 498 propose une installation à chargement/déchargement automatique dans laquelle les conteneurs sont engagés sur les chariots transversalement à leur axe de déplacement. Toutefois, cette installation utilise des postes de chargement/déchargement relativement complexes et coûteux.Another type of device disclosed in particular by German patent DE 33 08 778 provides removable containers which can be locked on self-propelled carriages. However, the drawback of this solution is that for the installation to function properly, the user must be present when the self-propelled trolley enters the station, either to load or unload it, and this so that it can be quickly reused for another mission. To eliminate this drawback, patent GB 2 194 498 proposes an automatic loading / unloading installation in which the containers are engaged on the carriages transversely to their axis of movement. However, this installation uses relatively complex and expensive loading / unloading stations.

L'invention a donc plus particulièrement pour but de supprimer tous ces inconvénients.The invention therefore more particularly aims to eliminate all these drawbacks.

Elle propose un appareil de transport du type susdit faisant intervenir des chariots automoteurs mobiles sur des rails et comprenant des moyens d'assemblage sur lesquels peuvent venir s'engager et se fixer temporairement des conteneurs amovibles, le chargement et le déchargement de ces conteneurs sur les chariots s'effectuant dans des postes de chargement et/ou de déchargement automatiques.It offers a transport device of the above type involving self-propelled mobile carriages on rails and comprising assembly means on which can be engaged and temporarily fix removable containers, loading and unloading of these containers on the trolleys carried out in automatic loading and / or unloading stations.

Selon l'invention, cet appareil est caractérisé en ce que lesdits moyens d'assemblage comprennent au moins un profil d'assemblage axé parallèlement à l'axe de déplacement du chariot, et destiné à coopérer avec un profil d'assemblage correspondant prévu sur les conteneurs, de manière à ce que l'assemblage ou le désassemblage puisse s'effectuer au terme d'une translation relative chariot/conteneur effectuée parallèlement audit axe de déplacement.According to the invention, this device is characterized in that said assembly means comprise at least one assembly profile axially parallel to the axis of movement of the carriage, and intended to cooperate with a corresponding assembly profile provided on the containers, so that assembly or disassembly can be carried out at the end of a relative carriage / container translation carried out parallel to said axis of movement.

Avantageusement, l'effort moteur nécessaire pour effectuer le mouvement de translation est exercé par le chariot lui-même.Advantageously, the motor force necessary to effect the translational movement is exerted by the carriage itself.

Dans ce cas, les postes de chargement devront comprendre des moyens permettant de placer les conteneurs en position d'assemblage, c'est-à-dire une position dans laquelle un chariot peut s'engager de lui-même par son profil d'assemblage sur le profil d'assemblage du conteneur.In this case, the loading stations must include means making it possible to place the containers in the assembly position, that is to say a position in which a trolley can engage itself by its assembly profile. on the container assembly profile.

Les postes de déchargement devront comprendre dans une zone de déchargement des moyens d'extraction agissant sur les conteneurs, de manière à les maintenir immobiles pendant la phase de désassemblage, c'est-à-dire pendant que le chariot effectue la translation produisant ce désassemblage.The unloading stations must include in an unloading zone extraction means acting on the containers, so as to keep them stationary during the disassembly phase, that is to say while the trolley performs the translation producing this disassembly .

Bien entendu, ces postes de chargement et/ou de déchargement pourront comprendre un distributeur permettant, soit d'amener les conteneurs dans la zone de chargement, soit d'ôter les conteneurs de la zone de déchargement.Of course, these loading and / or unloading stations may include a dispenser making it possible either to bring the containers into the loading area, or to remove the containers from the unloading area.

Sur la figure 1, le conteneur C représenté en perspective comporte sur chaque flancs latéraux des bossages longitudinaux 1. Ces bossages 1 se retrouvent d'une façon symétrique en partie haute et basse du conteneur C. Les bossages 1 présentent à chaque extrémité des plans inclinés 2 facilitant leur insertion dans les glissières 12 du chariot représenté sur la figure 2.In FIG. 1, the container C shown in perspective has on each lateral flanks longitudinal bosses 1. These bosses 1 are found symmetrically in the upper and lower part of the container C. The bosses 1 have at each end inclined planes 2 facilitating their insertion into the slides 12 of the carriage shown in FIG. 2.

Le couvercle 3 du conteneur C s'ouvre sur la face la plus grande et son plan de joint est repéré par la référence 4. Le couvercle 3 du conteneur est équipé d'une fermeture 5 sur l'une des faces les plus petites et d'une charnière sur l'autre face.The cover 3 of the container C opens on the largest side and its parting line is identified by the reference 4. The cover 3 of the container is equipped with a closure 5 on one of the smallest sides and d 'a hinge on the other side.

Selon une variante non illustrée, la fermeture 5 forme en même temps charnière. Dans ce cas, les petites faces opposées du conteneur sont équipées de la fermeture charnière 5. Il est alors possible d'ouvrir le couvercle 3 indifféremment sur l'une quelconque des petites faces, voire démonter le couvercle en actionnant simultanément les deux fermetures charnières 5 se trouvant sur les faces opposées.According to a variant not illustrated, the closure 5 forms at the same time a hinge. In this case, the small opposite sides of the container are equipped with the hinge closure 5. It is then possible to open the cover 3 either on any of the small faces, or even dismantle the cover by simultaneously actuating the two hinge closings 5 on the opposite sides.

En référence à la figure 2, le chariot automoteur 11 est équipé d'un module glissière 12 axé parallèlement à l'axe de déplacement XX'. L'ensemble glissière 12 comporte en son centre un dispositif de verrouillage 15 électrocommandé qui comprend un téton escamotable destiné à s'engager dans une cavité 6 prévue dans le conteneur. Un contrôle électrique ou électronique 17 vérifie la position correcte du dispositif de verrouillage 15.With reference to FIG. 2, the self-propelled carriage 11 is equipped with a slide module 12 axially parallel to the axis of movement XX '. The slide assembly 12 comprises in its center an electrically controlled locking device 15 which comprises a retractable stud intended to engage in a cavity 6 provided in the container. An electrical or electronic control 17 checks the correct position of the locking device 15.

Sur la figure 3, on comprend que lors de son déplacement dans le sens de la flèche, la glissière 12 du chariot 11 s'engage sur les bossages 1 du conteneur C. Le dispositif de verrouillage 15 rend solidaire le chariot 11 du conteneur lorsqu'il vient loger le téton escamotable dans la cavité 6 du conteneur.In FIG. 3, it can be understood that during its movement in the direction of the arrow, the slide 12 of the carriage 11 engages on the bosses 1 of the container C. The locking device 15 makes the carriage 11 of the container integral when it accommodates the retractable stud in the cavity 6 of the container.

La vue en coupe suivant A (figure 4) du chariot 11 de la figure 2 met en évidence la façon dont le dispositif de verrouillage 15 rend solidaire le conteneur C et ses bossages 3 par l'intermédiaire de la glissière 12.The sectional view along A (FIG. 4) of the carriage 11 of FIG. 2 shows how the locking device 15 makes the container C and its bosses 3 integral by means of the slide 12.

Dans l'exemple représenté sur les figures 1 à 4, l'ensemble glissière 2 présente une section transversale sensiblement en forme de U avec les extrémités supérieures des deux branches verticales du U repliées vers l'intérieur.In the example shown in Figures 1 to 4, the slide assembly 2 has a substantially U-shaped cross section with the upper ends of the two vertical branches of the U folded inward.

Bien entendu, l'invention ne se limite pas à une telle disposition.Of course, the invention is not limited to such an arrangement.

Ainsi, l'ensemble glissière pourrait comprendre au lieu d'une structure fixe, deux éléments profilés parallèles en forme de C, 22, 22', de concavité mutuellement en regard, ces deux éléments 22, 22' (qui correspondent aux branches verticales précédemment mentionnées) étant mobiles l'un par rapport à l'autre, sous l'action d'un mécanisme d'actionnement non représenté de manière à passer d'une position ouverte facilitant l'insertion ou l'extraction du conteneur C à une position fermée dans laquelle ils viennent étroitement épouser les bossages 1 du conteneur C (position représentée sur la figure 6C).Thus, the slide assembly could include, instead of a fixed structure, two parallel C-shaped profiled elements, 22, 22 ′, of concavity facing each other, these two elements 22, 22 ′ (which correspond to the vertical branches previously mentioned) being movable relative to each other, under the action of an actuation mechanism not shown so as to pass from an open position facilitating the insertion or extraction of the container C to a closed position in which they closely match the bosses 1 of the container C (position shown in Figure 6C).

Les déplacements des éléments profilés 22, 22' peuvent s'effectuer en translation, comme représenté sur la figure 6B ou en basculement comme illustré figure 6A.The displacements of the profiled elements 22, 22 ′ can be carried out in translation, as shown in FIG. 6B or in tilting as illustrated in FIG. 6A.

La forme des éléments profilés pourra être conçue de manière à assurer en plus de la préhension du conteneur C, un verrouillage efficace de ce conteneur C sur le chariot automoteur 11, notamment pendant le trajet entre deux stations.The shape of the profiled elements could be designed so as to ensure, in addition to gripping the container C, effective locking of this container C on the self-propelled carriage 11, in particular during the journey between two stations.

La figure 7 montre la structure d'un poste de chargement déchargement qui équipe une voie principale 31.FIG. 7 shows the structure of a loading and unloading station which equips a main track 31.

Ce poste comprend une voie de chargement/déchargement 32 qui suit un trajet carré ou rectangulaire, ouvert au niveau d'une région angulaire du carré ou du rectangle ainsi réalisé.This station includes a loading / unloading path 32 which follows a square or rectangular path, open at an angular region of the square or rectangle thus produced.

Cette voie de chargement/déchargement comprend plus particulièrement :

  • un premier tronçon rectiligne 33 qui s'étend parallèlement à la voie principale 31 et qui est associé à celle-ci grâce à un aiguillage par translation 34 conçu pour transborder le chariot automoteur 11, muni ou non de son conteneur 4, de la voie principale 31 au tronçon rectiligne 33 ou, inversement, de ce tronçon rectiligne 33 à la voie principale 31,
  • une section de déchargement comprenant un second tronçon de voie rectiligne 35 raccordé à une extrémité du tronçon 33 par l'intermédiaire d'une portion courbe à 90°, 36,
  • une section de chargement comprenant successivement :
    • . un troisième tronçon de voie rectiligne 38 raccordé à la deuxième extrémité du premier tronçon 33 par l'intermédiaire d'une seconde portion courbe 37,
    • . un quatrième tronçon de voie rectiligne 40 raccordé au troisième tronçon par une troisième portion courbe 39, ce troisième tronçon 40 s'étendant parallèlement au premier tronçon 33 et étant équipé à son extrémité d'un dispositif de chargement automatique.
This loading / unloading route more particularly includes:
  • a first rectilinear section 33 which extends parallel to the main track 31 and which is associated therewith by means of a translational switch 34 designed to tranship the self-propelled carriage 11, whether or not equipped with its container 4, from the main track 31 to the straight section 33 or, conversely, from this straight section 33 to the main track 31,
  • an unloading section comprising a second straight track section 35 connected at one end of the section 33 via a 90 ° curved portion, 36,
  • a loading section successively comprising:
    • . a third straight track section 38 connected to the second end of the first section 33 via a second curved portion 37,
    • . a fourth straight track section 40 connected to the third section by a third curved portion 39, this third section 40 extending parallel to the first section 33 and being equipped at its end with an automatic loading device.

Au-dessus du tronçon 35 de la section de déchargement, est disposé un convoyeur 42 conçu de manière à venir en prise sur (es bossages supérieurs 1 des conteneurs C amenés par les chariots automoteurs 11 dans l'aire de déchargement.Above the section 35 of the unloading section, is arranged a conveyor 42 designed so as to come into engagement with the upper bosses 1 of the containers C brought by the self-propelled carriages 11 into the unloading area.

Une fois le désassemblage chariot 11/conteneur C réalisé par un retour en marche arrière du chariot 11, le conteneur C reste suspendu sur le convoyeur 42. Celui-ci peut alors présenter une pente de manière à permettre au conteneur C de se déplacer sous l'effet de son propre poids, jusqu'à une aire de stockage.Once the carriage 11 / container C has been disassembled by reversing the carriage 11 in reverse, the container C remains suspended on the conveyor 42. The latter can then have a slope so as to allow the container C to move under the effect of its own weight, up to a storage area.

L'aire de chargement 41 associée au tronçon 40 de la section de chargement comprend deux zones de chargement successives Z₁, Z₂ sur lesquelles des conteneurs C peuvent être centrés de manière à pouvoir s'assembler automatiquement sur le chariot 11 et s'y verrouiller de la façon précédemment décrite.The loading area 41 associated with the section 40 of the loading section comprises two successive loading zones Z₁, Z₂ on which containers C can be centered so as to be able to assemble automatically on the carriage 11 and lock therefrom. the way previously described.

On constate qu'aussi bien le poste de chargement que le poste de déchargement peuvent être réalisés sans faire appel à des distributeurs complexes.It can be seen that both the loading station and the unloading station can be produced without the need for complex distributors.

L'invention n'exclut pas cependant l'utilisation de distributeurs.The invention does not however exclude the use of dispensers.

Ainsi, dans l'exemple représenté sur la figure 8, le poste de chargement 43 fait intervenir un distributeur constitué par un simple tiroir 43 permettant d'amener et de positionner le conteneur dans l'aire de chargement Z'. Ce tiroir 43 est mobile entre deux positions, à savoir :

  • une position d'attente représentée en traits interrompus sur la figure 8 (position dans laquelle il peut recevoir un conteneur),
  • une position transitoire de mise en place du conteneur C dans l'aire de chargement Z' (position représentée en traits pleins).
Thus, in the example shown in Figure 8, the loading station 43 involves a dispenser consisting of a simple drawer 43 for bringing and positioning the container in the loading area Z '. This drawer 43 is movable between two positions, namely:
  • a waiting position shown in broken lines in FIG. 8 (position in which it can receive a container),
  • a transient position for placing the container C in the loading area Z '(position shown in solid lines).

Dans cet exemple, le poste de déchargement comprend à la suite du convoyeur 42 décrit en regard de la figure 7, un deuxième convoyeur incliné 44 sur lequel la partie inférieure des conteneurs C vient en appui.In this example, the unloading station comprises, following the conveyor 42 described with reference to FIG. 7, a second inclined conveyor 44 on which the lower part of the containers C comes to bear.

L'invention ne se limite pas non plus à une forme déterminée du profil d'assemblage.The invention is also not limited to a specific shape of the assembly profile.

Ainsi, au lieu des bossages, le conteneur C pourrait comprendre des concavités prismatiques 144, par exemple de section en queue d'aronde comme représenté sur la figure 9.Thus, instead of the bosses, the container C could include prismatic concavities 144, for example of dovetail section as shown in FIG. 9.

Dans ce cas, les glissières pourront être réalisées à l'aide d'un tronçon de profilé 45 de section sensiblement en forme de U dont la base est fixée sur le chariot 11 et dont les branches verticales présentent des nervurations 46 de forme sensiblement complémentaire à celle des concavités prismatiques 144.In this case, the slides can be produced using a section of section 45 of section substantially U-shaped, the base of which is fixed to the carriage 11 and the vertical branches of which have ribs 46 of shape substantially complementary to that of prismatic concavities 144.

Les figures 10 et 11 illustrent un mode d'exécution particulièrement avantageux d'un poste de chargement et/ou de déchargement.Figures 10 and 11 illustrate a particularly advantageous embodiment of a loading and / or unloading station.

Dans cet exemple, l'aire de chargement/déchargement 47 est située dans un plan horizontal perpendiculaire à la voie 48. Elle consiste en le plateau d'un convoyeur à bandes 49 qui s'étend de part et d'autre de la voie 48.In this example, the loading / unloading area 47 is located in a horizontal plane perpendicular to the track 48. It consists of the plate of a belt conveyor 49 which extends on either side of the track 48 .

Au cours d'une phase de déchargement, l'ensemble chariot 11/conteneur C est amené dans le poste de déchargement 47 jusqu'à ce que la face antérieure du conteneur C vienne en appui sur l'aire de déchargement. Le chariot 11 s'immobilise dans cette position, procède au déverrouillage du conteneur C, puis repart en marche arrière en se désolidarisant du conteneur C. Le transporteur à bandes 49 est alors actionné de manière à amener le conteneur C dans une zone de stockage située à gauche ou à droite de la voie.During an unloading phase, the carriage 11 / container C assembly is brought into the unloading station 47 until the front face of the container C comes to bear on the unloading area. The carriage 11 comes to a standstill in this position, unlocks the container C, then sets off in reverse while disengaging from the container C. The conveyor belt 49 is then actuated so as to bring the container C to a storage area located left or right of the track.

Grâce à une telle disposition, le chargement d'un conteneur peut s'effectuer par un processus rigoureusement inverse de celui du déchargement.Thanks to such an arrangement, the loading of a container can be carried out by a process strictly opposite to that of unloading.

Il apparait donc que l'invention permet de résoudre à l'aide de moyens particulièrement simples et peu coûteux les problèmes précédemment évoqués qui, jusqu'ici, constituaient un frein au développement de ce type d'appareils de transport de charge.It therefore appears that the invention makes it possible to solve, by means of particularly simple and inexpensive means, the problems previously mentioned which, hitherto, constituted an obstacle to the development of this type of load transport apparatus.
