la figure 2 représente une vue latérale du dispositif de la figure 1.The appended drawing, which is purely indicative and not limiting, allows a better understanding of the object of the present invention.
Figure 1 is a schematic top view of the device according to the invention; and
FIG. 2 represents a side view of the device of FIG. 1.

Si l'on se réfère aux figures susmentionnées, le dispositif selon l'invention comprend un corps 1 présentant un soubassement 2 et des épaulements latéraux 3 et 4 qui délimitent une embrasure ou un couloir 5 où est placé un véhicule ou un camion 6. Le corps 1 est placé, de préférence de manière fixe, en face d'un système 8 déterminé, pouvant décharger (et/ou charger) de (sur) un wagon des marchandises (par exemple, posées sur des plates-formes ou des supports) et charger (et/ou décharger) les marchandises en question dans le véhicule 6. If we refer to the aforementioned figures, the device according to the invention comprises a body 1 having a base 2 and lateral shoulders 3 and 4 which delimit a doorway or a corridor 5 where a vehicle or a truck is placed 6. The body 1 is placed, preferably fixedly, in front of a determined system 8, capable of unloading (and / or loading) goods from (on) a wagon (for example, placed on platforms or supports) and load (and / or unload) the goods in question into the vehicle 6.

Ce dernier est retenu, pendant lesdites opérations, à l'intérieur du couloir 5 du corps 1 par des dispositifs hydrauliques ou pneumatiques 10 présentant un cylindre 11, fixé auxdits épaulements 3 et 4, dans lequel passe un piston 12 pouvant entrer en contact avec les parois 13 du véhicule 6 de manière à le retenir pendant lesdites opérations de chargement et/ou de déchargement. The latter is retained, during said operations, inside the corridor 5 of the body 1 by hydraulic or pneumatic devices 10 having a cylinder 11, fixed to said shoulders 3 and 4, through which passes a piston 12 which can come into contact with the walls 13 of vehicle 6 so as to retain it during said loading and / or unloading operations.

Le véhicule 6 repose sur un plan ou des parties de plan 15 (telles qu'elles sont représentées) mobiles transversalement par rapport à l'axe longitudinal A du corps 1. Chaque partie de plan (15) est associée latéralement à un élément élastique 18 relié à l'épaulement 3 ou 4 adjacent ladite partie 15, en outre, est mobile sur un ensemble de glissières à galets 19 (ou éléments similaires) situées sur le soubassement 2 selon des axes longitudinaux K parallèles à l'axe A du corps 1. The vehicle 6 rests on a plane or plane parts 15 (as shown) movable transversely relative to the longitudinal axis A of the body 1. Each plane part (15) is associated laterally with an elastic element 18 connected to the shoulder 3 or 4 adjacent said part 15, in addition, is movable on a set of roller slides 19 (or similar elements) located on the base 2 along longitudinal axes K parallel to the axis A of the body 1 .

Sur chaque partie 15, enfin, reposent les roues 20 du véhicule 6. Finally, on each part 15, the wheels 20 of the vehicle 6 rest.

Le dispositif faisant l'objet de l'invention comprend en outre avantageusement des détecteurs de proximité 21, 22, 23, disposés à proximité des parties antérieures, postérieures et frontales du véhicule 6. The device which is the subject of the invention also advantageously comprises proximity detectors 21, 22, 23, disposed near the front, rear and front parts of the vehicle 6.

Il est préférable qu'unie unité de commande 25, de préférence un circuit à microprocesseur, soit reliée aux détecteurs 21, 22, 23 et contrôle et commande le fonctionnement des dispositifs 10 afin d'obtenir un positionnement optimal du véhicule 6 par rapport au système de chargement et de déchargement. It is preferable that a control unit 25, preferably a microprocessor circuit, is connected to the detectors 21, 22, 23 and monitors and controls the operation of the devices 10 in order to obtain optimal positioning of the vehicle 6 relative to the system loading and unloading.

Supposons maintenant qu'il faille décharger des marchandises (non représentées) d'un wagon déterminé (également non représenté) et les charger sur le véhicule 6. Pour ce faire, ledit véhicule sera amené à l'intérieur du couloir 5 du corps 1 jusqu'à ce que les détecteurs de proximité 21 et 22 détectent son positionnement en face, par exemple, des parties mobiles 15. Un éventuel avertisseur sonore et/ou lumineux 30 situé à proximité d'une entrée 31 du couloir 5 signale alors que le véhicule 6 a atteint la position désirée à l'intérieur du couloir 5. Suppose now that it is necessary to unload goods (not shown) from a specific wagon (also not shown) and load them on the vehicle 6. To do this, said vehicle will be brought inside the corridor 5 of the body 1 up to 'that the proximity detectors 21 and 22 detect its positioning opposite, for example, the moving parts 15. A possible sound and / or light alarm 30 located near an entrance 31 of the corridor 5 then signals that the vehicle 6 has reached the desired position inside lane 5.

A ce stade, l'unité 25 commande les dispositifs 10 dont les pistons 12 entrent en contact avec les flancs 13 du véhicule 6 et centrent ce dernier par rapport au système 8 en le déplaçant à l'intérieur du couloir 5. Ce déplacement se fait grâce à la mobilité des parties 15 sur les galets 19. At this stage, the unit 25 controls the devices 10, the pistons 12 of which come into contact with the sides 13 of the vehicle 6 and center the latter relative to the system 8 by moving it inside the corridor 5. This movement takes place thanks to the mobility of the parts 15 on the rollers 19.

Il est à noter que l'actionnement des dispositifs 10 est contrôlé (et éventuellement différencié) par l'unité 25 en fonction de la détection de la position du véhicule 6 par les dispositifs 21, 22 et 23.It should be noted that the actuation of the devices 10 is controlled (and possibly differentiated) by the unit 25 as a function of the detection of the position of the vehicle 6 by the devices 21, 22 and 23.

Une fois que le véhicule 6 a été centré par rapport au système 8, les marchandises déchargées du wagon sont chargées dans le camion. Once the vehicle 6 has been centered relative to the system 8, the goods unloaded from the wagon are loaded into the truck.

Il a été décrit un mode particulier de réalisation de l'invention. D'autres variantes sont toutefois possibles (comme celle où, par exemple, un bras mécanique associé au soubassement 2 du corps 1 entraîne le véhicule 6 à l'intérieur du couloir 5) sans quitter pour autant le cadre du présent document. A particular embodiment of the invention has been described. Other variants are however possible (such as that where, for example, a mechanical arm associated with the base 2 of the body 1 drives the vehicle 6 inside the corridor 5) without leaving the scope of this document.
