Description

La présente invention concerne les systèmes de connexion électrique en générale et porte, plus particulièrement, sur un système de connexion électrique, pouvant être disposé sur les cellules de stockage, du type conteneurs ou caisses, utilisées dans le transport de denrées périssables par voie aérienne, maritime, ferroviaire ou routière.The present invention relates to electrical connection systems in general and relates, more particularly, to an electrical connection system, which can be placed on storage cells, of the container or crate type, used in the transport of perishable foodstuffs by air, maritime, rail or road.

Le marché des denrées périssables implique un transport de très haute qualité. Cette très haute qualité se traduit par un certain nombre d'exigence, dont notamment l'utilisation de cellules de stockage de manière à permettre un transport performant assurant la continuité de la chaine de froid. Ce marché des denrées périssables a de plus en plus souvent recours à la protection thermique en raison d'impératifs réglementaires ou d'impératifs techniques tels que la préréfrigération de certains fruits et légumes. Le transport doit donc être réalisé au moyen d'un véhicule respectant impérativement des normes techniques concernant l'isothermie de la cellule de stockage et les caractéristiques du groupe frigorifique.The perishable food market involves very high quality transport. This very high quality is reflected in a number of requirements, including the use of storage cells so as to allow efficient transport ensuring the continuity of the cold chain. This market for perishable foodstuffs increasingly uses thermal protection due to regulatory or technical requirements such as the pre-cooling of certain fruits and vegetables. Transport must therefore be carried out by means of a vehicle which imperatively complies with technical standards concerning the thermal insulation of the storage cell and the characteristics of the refrigeration unit.

Conformément à l'état de la technique connu, l'intégrité de la chaine du froid est garantie par l'installation et la mise en oeuvre de connecteurs électriques du type manuel. Ces connecteurs électriques manuels sont disposés en partie sur les cellules et en partie sur la plateforme du moyen de transport ou sur la plateforme fixe de stockage des cellules de stockage.In accordance with the known state of the art, the integrity of the cold chain is guaranteed by the installation and implementation of electrical connectors of the manual type. These manual electrical connectors are arranged partly on the cells and partly on the platform of the means of transport or on the fixed platform for storing the storage cells.

Le document US-A-4 959 020 décrit un connecteur automatique comprenant une trappe dans la cellule de stockage qui porte un contact électrique et qui se laisse ouvrir par un mécanisme sur la plateforme fixe de stockage, ce mécanisme insérant en même temps l'autre contact électrique et faisant une connexion avec le premier contact.Document US-A-4 959 020 describes an automatic connector comprising a hatch in the storage cell which carries an electrical contact and which can be opened by a mechanism on the fixed storage platform, this mechanism simultaneously inserting the other electrical contact and making a connection with the first contact.

Un inconvénient majeur des connecteurs électriques de l'art antérieur est le risque important d'arracher les connecteurs électriques lors des chargements et/ou déchargements des cellules de stockage.A major drawback of the electrical connectors of the prior art is the significant risk of tearing off the electrical connectors during the loading and / or unloading of the storage cells.

Un autre inconvénient majeur des connecteurs électriques manuels de l'art antérieur est leur manque de souplesse ainsi qu'une perte de temps lors de chaque manutention.Another major disadvantage of manual electrical connectors of the prior art is their lack of flexibility and a waste of time during each handling.

De plus, il est bien connu que toute opération manuelle dans laquelle intervient des connecteurs électriques présente un risque important pour les personnes.In addition, it is well known that any manual operation involving electrical connectors presents a significant risk for people.

Un objet de la présente invention est un système de connexion électrique ne présentant pas les inconvénients des dispositifs de l'état de la technique.An object of the present invention is an electrical connection system which does not have the drawbacks of the devices of the prior art.

Un autre objet de la présente invention est un système de connexion électrique ne perturbant pas les systèmes mécaniques standards de fixation ou de positionnement préexistants, pièces d'arrimage et supports de préhension par pinces.Another object of the present invention is an electrical connection system which does not disturb the standard mechanical fixing or pre-existing positioning systems, lashing parts and gripping supports by clamps.

L'invention porte donc sur un système de connexion électrique mis en oeuvre lors du chargement ou du déchargement de cellules de stockage sur ou d'une plateforme de transport.The invention therefore relates to an electrical connection system implemented during the loading or unloading of storage cells on or of a transport platform.

Conformément à l'invention le système de connexion électrique comprend des moyens de connexion électrique constitués d'au moins un connecteur du type mâle et d'au moins un connecteur du type femelle, l'un étant fixé à la plateforme de transport ou à la cellule de stockage, l'autre étant mû par un élément de positionnement fixé à la cellule de stockage ou à la plateforme de transport, respectivement; des moyens de commande, fixés à la cellule de stockage ou à la plateforme de transport, permettant de commander de façon hydraulique l'élément de positionnement de manière à établir la connexion électrique entre lesdits connecteurs et comprenant des éléments du type retardateur de telle manière que la commande de l'élément de positionnement du connecteur électrique mobil ne soit effective, lors du chargement de la cellule de stockage, qu'après que ladite cellule de stockage soit positionnée sur la plateforme de transport dans une position préétablie.According to the invention, the electrical connection system comprises electrical connection means constituted by at least one connector of the male type and at least one connector of the female type, one being fixed to the transport platform or to the storage cell, the other being moved by a positioning element fixed to the storage cell or to the transport platform, respectively; control means, fixed to the storage cell or to the transport platform, making it possible to hydraulically control the positioning element so as to establish the electrical connection between said connectors and comprising elements of the retarder type such that control of the positioning element of the mobile electrical connector is effective, when loading the storage cell, only after said storage cell is positioned on the transport platform in a preset position.

Un avantage du dispositif de connexion de l'invention est que la connexion électrique est différée dans le temps.An advantage of the connection device of the invention is that the electrical connection is delayed over time.

Le système de connexion électrique de l'invention est décrit ci-après selon un mode de réalisation préféré en référence aux dessins joints, dessins dans lesquels:

  • la figure 1 est une vue en perspective schématique d'un système de connexion électrique conforme à l'invention;
  • la figure 2 est une vue schématique en coupe partielle du système de connexion électrique conforme à l'invention;
  • les figures 3 à 7 sont des vues en coupe d'un mode de réalisation préféré du moyen de commande de type hydraulique représenté dans des positions caractéristiques.
The electrical connection system of the invention is described below according to a preferred embodiment with reference to the accompanying drawings, drawings in which:
  • Figure 1 is a schematic perspective view of an electrical connection system according to the invention;
  • Figure 2 is a schematic view in partial section of the electrical connection system according to the invention;
  • Figures 3 to 7 are sectional views of a preferred embodiment of the hydraulic type control means shown in characteristic positions.

Le système de connexion électrique représenté à la figure 1 comprend des moyens de connexion électrique 3 ainsi que des moyens de commande 7. Les moyens de connexion électrique 3 sont constitués d'au moins un connecteur de type mâle 4 ou 5 et d'au moins un connecteur de type femelle 5 ou 4. L'un des connecteurs est fixé à la plateforme de transport 2 ou à la cellule de stockage 1. L'autre connecteur est mû par un élément de positionnement 6 fixé à la cellule de stockage 1 ou à la plateforme de transport 2. Les moyens de commande 7, fixés à la cellule de stockage 1 ou à la plateforme de transport 2, permettent de commander l'élément de positionnement 6 qui lui est associé de manière à établir une connexion électrique à l'aide desdits connecteurs 4,5. Ces moyens de commande 7 sont connectés à l'élément de positionnement 6 à l'aide d'éléments de connexions 9. Ces moyens de commande 7 comprennent un élément de type retardateur 8 de manière à ce que la commande de l'élément de positionnement 6 du connecteur électrique mobile 4 ou 5 ne soit effective, lors du chargement de la cellule de stockage 1, qu'après que ladite cellule de stockage 1 soit positionnée sur la plateforme de transport dans une position préétablie.The electrical connection system shown in FIG. 1 comprises electrical connection means 3 as well as control means 7. The electrical connection means 3 consist of at least one male type connector 4 or 5 and at least a female type connector 5 or 4. One of the connectors is fixed to the transport platform 2 or to the storage cell 1. The other connector is moved by a positioning element 6 fixed to the storage cell 1 or to the transport platform 2. The control means 7, fixed to the storage cell 1 or to the transport platform 2, make it possible to control the positioning element 6 which is associated with it so as to establish an electrical connection to the using said connectors 4,5. These control means 7 are connected to the positioning element 6 by means of connection elements 9. These control means 7 comprise a delay-type element 8 so that the control of the positioning element 6 of the mobile electrical connector 4 or 5 is effective, when loading the storage cell 1, only after said storage cell 1 is positioned on the transport platform in a preset position.

Lors du chargement de la cellule de stockage 1 sur la plateforme de transport 2, le moyen de commande 7, du fait qu'il est connecté à l'élément de positionnement 6 par des éléments de connection 9, est actionné de telle manière que l'élément de positionnement 6 positionne le connecteur mobil 4 ou 5 en butée contre le connecteur fixe 5 ou 4. Le mode d'obtention de ces connexions mécaniques puis électriques sera décrit ci-dessous, de façon plus détaillé, dans un mode de réalisation, de type hydraulique, du moyen de commande 7.When loading the storage cell 1 on the transport platform 2, the control means 7, because it is connected to the positioning element 6 by connection elements 9, is actuated in such a way that the positioning element 6 positions the mobile connector 4 or 5 in abutment against the fixed connector 5 or 4. The method of obtaining these mechanical then electrical connections will be described below, in more detail, in one embodiment, hydraulic type, control means 7.

La figure 2 montre une vue schématique en coupe partielle d'un mode de réalisation préféré du moyen de commande 7, en position de repos, connecté à l'élément de positionnement 6 associé. La position de repos est obtenue lorsque la cellule de stockage est déchargée de la plateforme de transport. Le piston temporisateur 8 décrit ci-après est alors en position basse dans le corps du cylindre distributeur 15. Conformément à ce mode de réalisation, le moyen de commande 7 est du type hydraulique et comprend un ressort 10, un piston flottant 11, une chambre 12 contenant un fluide 13, un piston temporisateur 8, l'ensemble étant disposé dans le corps du cylindre distributeur 15 de manière à former un dispositif distributeur hydraulique, et un ressort de rappel 14 disposé le long de la tige externe du piston temporisateur 8. La chambre 12 est délimitée par l'espace compris dans le corps du cylindre distributeur 15 par le piston flottant 11 et le piston temporisateur 8. Le piston flottant 11 est maintenu par le ressort 10, d'une part, et par le fluide 13, d'autre part, de telle manière que le fluide soit comprimé.FIG. 2 shows a schematic view in partial section of a preferred embodiment of the control means 7, in the rest position, connected to the associated positioning element 6. The rest position is obtained when the storage cell is unloaded from the transport platform. The timer piston 8 described below is then in the low position in the body of the distributor cylinder 15. According to this embodiment, the control means 7 is of the hydraulic type and comprises a spring 10, a floating piston 11, a chamber 12 containing a fluid 13, a timer piston 8, the assembly being disposed in the body of the distributor cylinder 15 so as to form a hydraulic distributor device, and a return spring 14 disposed along the external rod of the timer piston 8. The chamber 12 is delimited by the space included in the body of the distributor cylinder 15 by the floating piston 11 and the timer piston 8. The floating piston 11 is held by the spring 10, on the one hand, and by the fluid 13, on the other hand, in such a way that the fluid is compressed.

Le corps du cylindre distributeur 15 comprend une buse d'arrivée 16 et une buse de sortie 17 du fluide 13. Dans la position de repos définie plus haut, la chambre 12 est reliée à la buse d'arrivée 16 par l'intermédiaire d'un canal 18 pratiqué, longitudinalement depuis la chambre 12 puis transversalement jusqu'à la buse d'arrivée 16, dans le corps du piston temporisateur 8.The body of the distributor cylinder 15 comprises an inlet nozzle 16 and an outlet nozzle 17 for the fluid 13. In the rest position defined above, the chamber 12 is connected to the inlet nozzle 16 via a channel 18 formed, longitudinally from the chamber 12 and then transversely to the inlet nozzle 16, in the body of the timer piston 8.

L'élément de positionnement 6 peut être ,par exemple, un vérin hydraulique à une chambre dont le piston 19 est solidaire, par exemple, du connecteur femelle 5.The positioning element 6 can be, for example, a hydraulic cylinder with a chamber, the piston 19 of which is integral, for example, with the female connector 5.

Dans le but d'éviter qu'une partie du fluide 13 contenu dans la chambre 12 ne soit injectée prématurément dans la chambre de l'élément de positionnement 6, la buse d'arrivée 16 est connectée à un clapet anti-retour 20 (cf. Figure 2) ne permettant l'écoulement du fluide 13 que de la chambre de l'élément de positionnement 6 vers la buse d'arrivée 16.In order to prevent part of the fluid 13 contained in the chamber 12 from being prematurely injected into the chamber of the positioning element 6, the inlet nozzle 16 is connected to a non-return valve 20 (cf. 2) allowing the fluid 13 to flow only from the chamber of the positioning element 6 towards the inlet nozzle 16.

Lors du chargement de la cellule de stockage 1 sur la plateforme de transport 2, le piston temporisateur 8 est actionné le premier et pénètre dans le corps du cylindre distributeur 15 (Figure 3) pour venir se positionner en position haute (Figure 4). Le canal d'alimentation 18 ouvert sur la chambre 12 et initialement sur la buse d'arrivée 16 vient se positionner face à la buse de sortie 17. Le fluide 13, comprimé par le ressort 10 et par le piston temporisateur 8 en position haute dans le corps du cylindre distributeur 15, est injecté dans la chambre de l'élément de positionnement 6 non représenté (Figure 5 et 6). L'injection du fluide 13 dans la chambre du vérin hydraulique provoque un déplacement du connecteur femelle jusqu'à ce que celui-ci soit en contact avec le connecteur mâle.When loading the storage cell 1 on the transport platform 2, the timer piston 8 is actuated first and enters the body of the distributor cylinder 15 (Figure 3) to come to position in the high position (Figure 4). The supply channel 18 open on the chamber 12 and initially on the inlet nozzle 16 is positioned opposite the outlet nozzle 17. The fluid 13, compressed by the spring 10 and by the timer piston 8 in the high position in the body of the distributor cylinder 15 is injected into the chamber of the positioning element 6, not shown (FIGS. 5 and 6). The injection of the fluid 13 into the chamber of the hydraulic cylinder causes the female connector to move until it is in contact with the male connector.

Lors du déchargement de la cellule de stockage 1 de la plateforme de transport 2, le piston temporisateur 8 est actionné et se déplace, sous l'action du ressort de rappel 14, en position basse dans le corps du cylindre distributeur 15 (Figure 7). Le canal d'alimentation 18 ouvert sur la chambre 12 et précédemment sur la buse de sortie 17 vient se positionner face à la buse d'arrivée 16.During the unloading of the storage cell 1 from the transport platform 2, the timer piston 8 is actuated and moves, under the action of the return spring 14, in the low position in the body of the distributor cylinder 15 (Figure 7) . The supply channel 18 open on the chamber 12 and previously on the outlet nozzle 17 is positioned facing the inlet nozzle 16.

Le fluide 13 dans la chambre de l'élément de positionnement 6 est aspiré dans la chambre 12 du fait de la dépression créée dans cette chambre 12 suite au déplacement du piston temporisateur 14 de sa position haute à sa position basse. Le fluide 13 est également chassé dans la chambre 12 du corps du cylindre distributeur 15 sous l'effet du retour automatique, à sa position de repos, du vérin du type simple effet.The fluid 13 in the chamber of the positioning element 6 is sucked into the chamber 12 due to the vacuum created in this chamber 12 following the displacement of the timer piston 14 from its high position to its low position. The fluid 13 is also expelled into the chamber 12 from the body of the distributor cylinder 15 under the effect of the automatic return, to its rest position, of the single-acting type cylinder.

Il en résulte que le piston 19 de l'élément de positionnement est ramené dans sa position initiale et que les connecteurs 4 et 5 ne sont plus connectés électriquement (cf. Figure 2).It follows that the piston 19 of the positioning element is returned to its initial position and that the connectors 4 and 5 are no longer electrically connected (see Figure 2).

De manière générale, la vitesse de déplacement du piston flottant 11 est fonction du système de manutention de la cellule de stockage 1. La vitesse de déplacement arrière V11 de ce piston flottant lors de l'injection du fluide 13 dans la chambre de l'élément de positionnement 6 est fonction du diamètre intérieur d17 de la buse de sortie 17 et de la pression P10 appliquée par le ressort 10 sur le fluide 13 par l'intermédiaire du piston flottant 11. La course du piston 19 de l'élément de positionnement 6 est fonction du diamètre de la chambre de cet élément de positionnement et du volume d'huile injecté dans cette chambre.In general, the speed of movement of the floating piston 11 depends on the handling system of the storage cell 1. The rear speed of movement V11 of this floating piston during the injection of the fluid 13 into the chamber of the element positioning 6 is a function of the internal diameter d17 of the outlet nozzle 17 and of the pressure P10 applied by the spring 10 to the fluid 13 by means of the floating piston 11. The stroke of the piston 19 of the positioning element 6 is a function of the diameter of the chamber of this positioning element and the volume of oil injected into this chamber.

A titre d'exemple, l'écart entre la buse d'entrée 16 et la buse de sortie 17 est de l'ordre de 15 mm.For example, the difference between the inlet nozzle 16 and the outlet nozzle 17 is of the order of 15 mm.

Il va de soit que les connecteurs électriques 4,5 sont reliés , par exemple au moyen de cables électriques (non représentés), respectivement, à un groupe réfrigérant (non représenté), fixé, par exemple, sur la cellule de stockage 1, et à une source d'alimentation électrique (non représentée), fixée, par exemple, sur la plateforme de transport 2.It goes without saying that the electrical connectors 4,5 are connected, for example by means of electrical cables (not shown), respectively, to a cooling unit (not shown), fixed, for example, to the storage cell 1, and to an electrical power source (not shown), fixed, for example, on the transport platform 2.

Le système de connexion décrit peut être utilisé sur tout type de cellule de stockage et tout type de plateforme fixe ou de transport.The connection system described can be used on any type of storage cell and any type of fixed or transport platform.

Les connecteurs 4 et 5 sont supportés par un système mécanique de rattrapage automatique de coaxialité (non représenté). Le jeu à rattraper est de l'ordre de plus ou moins 30 mm du fait qu'il est limité par les positions relatives de l'axe de la cheville de la plateforme de transport 2 par rapport à l'axe de la pièce de coin de la cellule de stockage 1.Connectors 4 and 5 are supported by a mechanical automatic coaxiality take-up system (not shown). The play to be made up is of the order of plus or minus 30 mm because it is limited by the relative positions of the axis of the pin of the transport platform 2 relative to the axis of the corner piece. storage cell 1.
