Description

CONTENEUR DE TRANSPORT DE PRODUITS A UNE PLAGE DE TEMPÉRATURE DESIREE CONTAINER FOR TRANSPORTING PRODUCTS AT A DESIRED TEMPERATURE RANGE
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention se rapporte au domaine technique de la conservation à température positive ou négative de produits contenus dans des récipients isothermes. L’invention concerne plus particulièrement un conteneur de transport présentant un volume inférieur à 150 L. The present invention relates to the technical field of storage at positive or negative temperature of products contained in isothermal containers. The invention relates more particularly to a transport container having a volume of less than 150 L.
Par produits, on entend par exemple des denrées périssables, et plus largement des produits dont la nature, la composition, l’origine ou la destination imposent des conditions de stockage et/ou d’entreposage stricts et contrôlés impliquant un maintien en température réduite, de manière à garantir leur intégrité en vue d’une utilisation ultérieure ou encore d’une consommation appropriée. The term “products” is understood to mean, for example, perishable foodstuffs, and more broadly products whose nature, composition, origin or destination impose strict and controlled storage and / or storage conditions involving keeping at reduced temperature, so as to guarantee their integrity with a view to subsequent use or even appropriate consumption.
Le type de conteneur de la présente invention trouve une application avantageuse dans le cas de vente par correspondance, impliquant un transport long, c’est-à-dire jusqu’à 15 heures par exemple. The type of container of the present invention finds an advantageous application in the case of mail order sales, involving long transport, that is to say up to 15 hours for example.
L’invention concerne également un procédé et une installation de chargement d’une charge frigorifique dans ce type de conteneur. The invention also relates to a method and an installation for loading a refrigeration charge into this type of container.
ART ANTERIEUR PRIOR ART
Dans le domaine des conteneurs de transport de produits, il est connu le document FR 2 802 186 qui décrit un conteneur comprenant : In the field of product transport containers, document FR 2 802 186 is known, which describes a container comprising:
- une caisse en matière isolante délimitant un compartiment ouvert vers le haut présentant un volume inférieur à 150 L et apte à contenir les produits ; - a box of insulating material delimiting an upwardly open compartment having a volume of less than 150 L and capable of containing the products;
- un couvercle en matière isolante adaptable sur la caisse pour obturer le compartiment ; - an insulating material cover adaptable to the body to close the compartment;
- une paroi intercalaire diffusante interposée entre la caisse et le couvercle pour délimiter avec le couvercle une chambre avec une surface de réception d’au moins une charge frigorifique, le couvercle et la paroi intercalaire comprenant des moyens complémentaires de verrouillage/déverrouillage l’un avec l’autre. - a diffusing intermediate wall interposed between the body and the cover to define with the cover a chamber with a receiving surface of at least one refrigeration charge, the cover and the intermediate wall comprising complementary locking / unlocking means with one another.
En théorie, ce type de conteneur assure depuis l’étape initiale de conditionnement des produits, jusqu’à l’étape finale d’utilisation ou de consommation, ainsi que pendant toute la durée de conditionnement et de transport s’écoulant entre ces deux étapes, un maintien à la température de conservation. In theory, this type of container ensures from the initial stage of packaging the products, until the final stage of use or consumption, as well as throughout the entire packaging and transport period between these two stages. , maintaining at the storage temperature.
Cependant, la durée du maintien en température de ce type de conteneur n’est en pratique pas bien maîtrisée. Par ailleurs, la charge frigorifique mise en place entre le couvercle et la paroi intercalaire est souvent surdimensionnée, ce qui entraîne un gaspillage et une augmentation du coût de revient du conteneur. However, the duration of the temperature maintenance of this type of container is not well controlled in practice. Furthermore, the refrigeration charge placed between the cover and the intermediate wall is often oversized, which results in waste and an increase in the cost of the container.
Enfin, ce type de conteneur est bien adapté à maintenir les produits à une température comprise entre -40°C et -18°C. En revanche, lorsqu’il convient de maintenir les denrées à une température plus étroite, notamment entre 0°C et 4°C, l’opération devient plus difficile, voire impossible. Finally, this type of container is well suited to maintaining products at a temperature between -40 ° C and -18 ° C. On the other hand, when food should be kept at a lower temperature, especially between 0 ° C and 4 ° C, the operation becomes more difficult, if not impossible.
EXPOSE DE L’INVENTION DISCLOSURE OF THE INVENTION
L’un des buts de l’invention et donc de remédier aux inconvénients de l’art antérieur en proposant un conteneur de transport de produits à une température de maintien désirée qui permette de maîtriser totalement la température à l’intérieur du conteneur, que ce soit à une plage de températures allant de -40°C à -18°C ou à une plage de températures allant de 0°C à 4°C par exemple. One of the aims of the invention and therefore to remedy the drawbacks of the prior art by proposing a container for transporting products at a desired holding temperature which makes it possible to completely control the temperature inside the container, whether this either at a temperature range from -40 ° C to -18 ° C or at a temperature range from 0 ° C to 4 ° C for example.
Un autre objectif de l’invention est de fournir un tel conteneur dont la quantité de charge frigorifique nécessaire est aussi maîtrisée, en évitant tout gaspillage. Another objective of the invention is to provide such a container in which the amount of refrigeration charge required is also controlled, while avoiding any waste.
À cet effet, il a été mis au point un conteneur de transport de produits à une plage de températures de maintien désirée, conforme à celui de l’état de la technique en ce qu’il comprend : - une caisse en matière isolante délimitant un compartiment ouvert vers le haut présentant un volume inférieur à 150 L et apte à contenir les produits ; For this purpose, it has been developed a container for transporting products at a desired holding temperature range, in accordance with that of the state of the art in that it comprises: - a box of insulating material delimiting an upwardly open compartment having a volume of less than 150 L and capable of containing the products;
- un couvercle en matière isolante adaptable sur la caisse pour obturer le compartiment ; - an insulating material cover adaptable to the body to close the compartment;
- une paroi intercalaire diffusante interposée entre la caisse et le couvercle pour délimiter avec le couvercle une chambre avec une surface de réception d’au moins une charge frigorifique, le couvercle et la paroi intercalaire comprenant des moyens complémentaires de verrouillage/déverrouillage l’un avec l’autre. - a diffusing intermediate wall interposed between the body and the cover to define with the cover a chamber with a receiving surface of at least one refrigeration charge, the cover and the intermediate wall comprising complementary locking / unlocking means one with the other.
En prenant en compte le fait que la caisse présente un pouvoir de dissipation calorifique déterminé, et que la charge frigorifique est adaptée pour émettre une énergie calorifique déterminée, l’invention consiste en ce que l’énergie calorifique émise par la charge frigorifique et le coefficient de diffusion thermique de la paroi intercalaire sont ajustés de sorte que, à températures de transport et de maintien déterminées et pendant une durée désirée après réception de la charge frigorifique et exposition du conteneur à la température de transport, la puissance calorifique diffusée par la paroi intercalaire vers le compartiment est égale, ou au maximum 20 % supérieure, à la puissance calorifique dissipée par la caisse vers l’extérieur. Taking into account the fact that the body has a determined heat dissipation capacity, and that the cooling load is adapted to emit a determined heat energy, the invention consists in that the heat energy emitted by the cooling load and the coefficient of thermal diffusion of the intermediate wall are adjusted so that, at determined transport and holding temperatures and for a desired period after receipt of the refrigeration charge and exposure of the container to the transport temperature, the heat output diffused by the intermediate wall to the compartment is equal to, or at most 20% greater than, the calorific power dissipated by the body to the outside.
De cette manière, l’invention permet de fournir un conteneur de transport adapté pour la livraison à domicile sur des durées relativement longues, de l’ordre d’une dizaine d’heures, en maîtrisant parfaitement la température à l’intérieur du conteneur. En effet, le conteneur est conçu pour prendre en compte notamment la température de transport, mais également la température de maintien, la durée désirée de transport, la puissance calorifique dissipée par la caisse, l’énergie calorifique émise par la charge frigorifique, et le coefficient de diffusion thermique de la paroi intercalaire. In this way, the invention makes it possible to provide a transport container suitable for home delivery over relatively long periods, of the order of ten hours, while perfectly controlling the temperature inside the container. Indeed, the container is designed to take into account in particular the transport temperature, but also the maintenance temperature, the desired duration of transport, the calorific power dissipated by the body, the calorific energy emitted by the refrigeration load, and the thermal diffusion coefficient of the intermediate wall.
Il en résulte également que la quantité de charge calorifique est parfaitement adaptée aux besoins réels. It also follows that the quantity of heat load is perfectly adapted to the real needs.
L’avantage de la présente invention est également de fournir un conteneur présentant une caisse dite standard, sur laquelle seuls le couvercle, la paroi intercalaire, et la charge frigorifïque sont adaptés à l’application désirée. D’une manière encore plus avantageuse, le couvercle est également standard. The advantage of the present invention is also to provide a container having a so-called standard box, on which only the cover, the intermediate wall, and the load. refrigerant are suitable for the desired application. Even more advantageously, the cover is also standard.
Pour faire varier le coefficient de diffusion thermique de la paroi intercalaire, il est possible de faire varier une pluralité de paramètres, tels que la surface de réception de la charge frigorifique, l’épaisseur de la paroi intercalaire, son matériau et sa densité, etc... To vary the thermal diffusion coefficient of the intermediate wall, it is possible to vary a plurality of parameters, such as the surface for receiving the refrigeration charge, the thickness of the intermediate wall, its material and its density, etc. ...
L’énergie calorifique émise par la charge frigorifique est, quant à elle, ajustée, pour une paroi intercalaire déterminée, en fonction de la nature de la charge frigorifique et sa quantité. The heat energy emitted by the refrigeration load is, for its part, adjusted, for a specific intermediate wall, depending on the nature of the refrigeration load and its quantity.
Selon une forme de réalisation particulière, la paroi intercalaire est perforée de manière à constituer un moyen d’ajustement complémentaire du coefficient de diffusion thermique. En effet, en pratique l’épaisseur de la paroi intercalaire peut être soumise à des contraintes de rigidité et d’épaisseur, de sorte qu’il peut être avantageux de ne pas diminuer l’épaisseur, mais de la perforer pour ajuster au mieux son coefficient de diffusion thermique. According to a particular embodiment, the intermediate wall is perforated so as to constitute a means of complementary adjustment of the thermal diffusion coefficient. Indeed, in practice the thickness of the intermediate wall may be subjected to constraints of rigidity and thickness, so that it may be advantageous not to reduce the thickness, but to perforate it to best adjust its thermal diffusion coefficient.
Avantageusement, et selon une autre caractéristique prise isolément des caractéristiques à la base de l’invention, ou bien en combinaison avec les caractéristiques précédentes, le couvercle et la paroi intercalaire sont indépendants l’un de l’autre et comprennent des moyens d’articulation complémentaires aptes à permettre le pivotement du couvercle, de préférence d’un angle compris entre 10° et 60° par rapport à la paroi intercalaire et selon un bord de pivotement, pour autoriser la mise en place de la charge frigorifique à l’intérieur de la chambre, sans dissocier le couvercle et la paroi intercalaire. Advantageously, and according to another characteristic taken in isolation from the characteristics at the basis of the invention, or else in combination with the preceding characteristics, the cover and the intermediate wall are independent of one another and comprise articulation means complementary devices capable of allowing the lid to pivot, preferably at an angle of between 10 ° and 60 ° relative to the intermediate wall and along a pivoting edge, to allow the installation of the refrigeration charge inside the the chamber, without separating the cover and the intermediate wall.
En d’autres termes, il pourrait tout à fait être envisagé de fournir un conteneur dont le couvercle et la paroi intercalaire sont indépendants l’un de l’autre et comprennent des moyens d’articulation complémentaires aptes à permettre le pivotement du couvercle par rapport à la paroi intercalaire et selon un bord de pivotement, pour autoriser la mise en place de la charge frigorifique à l’intérieur de la chambre, sans mettre en œuvre l’ajustement de l’énergie calorifique émise par la charge frigorifique et du coefficient de diffusion thermique de la paroi intercalaire. Selon une forme de réalisation particulière, les moyens d’articulation du couvercle comprennent au moins une rainure disposée le long du bord de pivotement du couvercle et en regard de la paroi intercalaire. Une nervure en saillie à section circulaire borde le côté intérieur de la rainure, c’est-à-dire le côté opposé au bord de pivotement, et les moyens d’articulation complémentaires de la paroi intercalaire comprennent au moins une rainure complémentaire à la nervure en saillie destinée à recevoir en engagement ladite nervure avec capacité de pivotement. In other words, it could very well be envisaged to provide a container whose cover and the intermediate wall are independent of one another and comprise complementary articulation means capable of allowing the cover to pivot relative to the other. to the intermediate wall and along a pivoting edge, to allow the installation of the refrigeration charge inside the chamber, without implementing the adjustment of the heat energy emitted by the refrigeration charge and of the coefficient of thermal diffusion of the intermediate wall. According to a particular embodiment, the articulation means of the cover comprise at least one groove arranged along the pivoting edge of the cover and opposite the intermediate wall. A projecting rib of circular section borders the inner side of the groove, that is to say the side opposite the pivoting edge, and the complementary articulation means of the intermediate wall comprise at least one groove complementary to the rib. projecting intended to receive in engagement said rib with pivoting capacity.
Selon une forme de réalisation particulière, les moyens de verrouillage/ déverrouillage du couvercle comprennent deux languettes latérales, chacune en saillie orthogonalement à partir d’un bord latéral du couvercle et en direction de la paroi intercalaire. Chaque languette présente à son extrémité libre un ergot faisant saillie en direction de la languette opposée, et les moyens de verrouillage/déverrouillage de la paroi intercalaire comprennent des bords latéraux en saillie vers le couvercle et dans lesquels sont ménagées des encoches complémentaires aux languettes latérales et aux ergots. According to a particular embodiment, the means for locking / unlocking the cover comprise two lateral tabs, each projecting orthogonally from a lateral edge of the cover and in the direction of the intermediate wall. Each tab has at its free end a lug projecting in the direction of the opposite tab, and the locking / unlocking means of the intermediate wall comprise lateral edges projecting towards the cover and in which notches are formed complementary to the lateral tabs and to the lugs.
Dans une forme de réalisation particulière, et dans un but de diminuer la consommation de la charge frigorifique, et en fonction de la température de transport du conteneur, tels que par exemple dans un camion à température dirigée, ou bien dans un camion à température ambiante, la surface de réception de la paroi intercalaire est divisée en deux zones de réception par une languette centrale perpendiculaire au bord de pivotement, en vue d’adapter la quantité de charge frigorifique à l’application désirée, par exemple en positionnant une charge frigorifique que dans l’une des zones. In a particular embodiment, and with the aim of reducing the consumption of the refrigerating load, and depending on the transport temperature of the container, such as for example in a temperature-controlled truck, or else in a truck at ambient temperature , the receiving surface of the intermediate wall is divided into two receiving zones by a central tab perpendicular to the pivoting edge, in order to adapt the quantity of refrigeration charge to the desired application, for example by positioning a refrigeration charge that in one of the zones.
Selon une forme de réalisation particulière, les moyens de verrouillage/ déverrouillage comprennent, seuls ou en combinaison avec les moyens précédemment décrits, deux languettes frontales en saillie orthogonalement à partir du bord du couvercle opposé au bord de pivotement, et en direction de la paroi intercalaire. Les deux languettes sont positionnées de part et d’autre de la languette centrale et délimitent entre elles une forme de retenue, l’extrémité de la languette centrale en regard de la forme de retenue comprend une forme de retenue complémentaire pour se verrouiller entre les deux languettes frontales. Dans une forme de réalisation préférée, le couvercle et la paroi intercalaire sont moulées dans un même matériau. According to a particular embodiment, the locking / unlocking means comprise, alone or in combination with the means described above, two front tongues projecting orthogonally from the edge of the cover opposite the pivoting edge, and in the direction of the intermediate wall. . The two tabs are positioned on either side of the central tab and define between them a form of retainer, the end of the central tongue facing the retainer form comprises a complementary form of retainer to lock between the two front tabs. In a preferred embodiment, the cover and the intermediate wall are molded from the same material.

Selon l’invention, et à partir d’une paroi intercalaire sur laquelle est posé le couvercle avec capacité de pivotement par rapport à la paroi intercalaire et selon un bord de pivotement, le procédé comprend des étapes consistant à : According to the invention, and from an intermediate wall on which the cover is placed with the ability to pivot relative to the intermediate wall and along a pivoting edge, the method comprises steps consisting of:

En référence aux figures 1 à 11, l’invention concerne un récipient (1) destiné à transporter des produits à une température de maintien désirée, par exemple à une température comprise entre -40°C et -18°C pour la conservation de produits surgelés, ou à une température comprise entre 0°C et 4°C pour la conservation des produits frais. Referring to Figures 1 to 11, the invention relates to a container (1) intended to transport products at a desired holding temperature, for example at a temperature between -40 ° C and -18 ° C for the conservation of products. frozen, or at a temperature between 0 ° C and 4 ° C for storing fresh products.
Le réservoir (1) comprend une caisse (2) en matériau isolant délimitant un compartiment ouvert sur le dessus et d’un volume inférieur à 150 L. The tank (1) comprises a box (2) of insulating material delimiting an open compartment on the top and a volume of less than 150 L.
Le compartiment est adapté pour contenir les produits à maintenir à température. La caisse (2) comporte avantageusement et intérieurement des conformations telles que des nervures (3) destinées à favoriser la circulation des calories pour établir un gradient de température constant aussi faible que possible en écart en tous points du compartiment. The compartment is suitable for containing the products to be kept at temperature. The body (2) advantageously and internally comprises conformations such as ribs (3) intended to promote the circulation of heat in order to establish a constant temperature gradient as low as possible in deviation at all points of the compartment.

En référence à la figure 2, le conteneur (1) comprend une paroi intercalaire (5) diffusante interposée entre la caisse (2) et le couvercle (4) pour délimiter avec le couvercle (4) une chambre avec une surface (7) de réception d’au moins une charge frigorifique (6) émettant une puissance calorifique. Referring to Figure 2, the container (1) comprises an intermediate wall (5) diffusing interposed between the box (2) and the cover (4) to define with the cover (4) a chamber with a surface (7) of reception of at least one refrigeration load (6) emitting calorific power.
La caisse (2), le couvercle (4) et la paroi intercalaire (5) sont constitués d’un matériau présentant de bonnes caractéristiques d’isolation thermique, associées à une faible densité. Par exemple, ce matériau peut être du polystyrène, expansé ou extrudé, ou du polyéthylène expansé, ou du polypropylène expansé offrant l’avantage supplémentaire de permettre aux différentes parties du conteneur (1) d’être réalisées par moulage. Le conteneur (1) présente une forme générale parallélépipédique rectangulaire, mais cette forme ne doit pas être considérée comme limitant la portée de l’invention. The box (2), the cover (4) and the intermediate wall (5) are made of a material having good thermal insulation characteristics, associated with a low density. For example, this material can be polystyrene, expanded or extruded, or expanded polyethylene, or expanded polypropylene offering the additional advantage of allowing the different parts of the container (1) to be produced by molding. The container (1) has a generally rectangular parallelepipedal shape, but this shape should not be considered as limiting the scope of the invention.
De ce qui précède, la caisse (2) présente un pouvoir de dissipation calorifique déterminée et la paroi intercalaire (5) présente un coefficient de diffusion thermique spécifique. From the above, the body (2) has a determined heat dissipation power and the intermediate wall (5) has a specific heat diffusion coefficient.
Selon l’invention, l’énergie calorifique émise par la charge frigorifique (6) et le coefficient de diffusion calorifique de la paroi intercalaire (5) sont ajustés de sorte que, à températures de transport et de maintien déterminées et pendant une durée désirée après réception de la charge frigorifique (6) et exposition du conteneur (1) à la température de transport, la puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment est égale ou au maximum 20% supérieure à la puissance calorifique dissipée par la caisse (2) vers l’extérieur. According to the invention, the heat energy emitted by the cooling load (6) and the heat diffusion coefficient of the intermediate wall (5) are adjusted so that, at determined transport and holding temperatures and for a desired period afterwards reception of the refrigeration charge (6) and exposure of the container (1) to the transport temperature, the calorific power diffused by the intermediate wall (5) towards the compartment is equal to or at most 20% greater than the calorific power dissipated by the body (2) to the outside.
La figure 2 illustre la puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment, et la puissance calorifique dissipée par la caisse (2) vers l’extérieur. Figure 2 illustrates the calorific power diffused by the intermediate wall (5) to the compartment, and the calorific power dissipated by the body (2) to the outside.
En effet, le conteneur de transport (1), selon l’invention, est destiné, par exemple, à la vente par correspondance, et en particulier à la livraison à domicile. A cet effet, après avoir placé une charge frigorifique (6) dans la chambre délimitée entre le couvercle (4) et la paroi intercalaire (5), le couvercle (4) et la paroi intercalaire (5) sont verrouillés l’un sur l’autre et positionnés sur la boîte (2) pour fermer le compartiment qui a préalablement reçu les produits à maintenir à température. Indeed, the transport container (1), according to the invention, is intended, for example, for mail order, and in particular for home delivery. For this purpose, after placing a refrigeration charge (6) in the chamber delimited between the cover (4) and the intermediate wall (5), the cover (4) and the intermediate wall (5) are locked one on the 'other and positioned on the box (2) to close the compartment which has previously received the products to be kept at temperature.
A ce stade, le conteneur de transport (1) est expédié et transporté dans des conditions particulières, c’est-à-dire pendant un certain temps, et en étant exposé à une température de transport, qui peut être une température ambiante ou une température spécifique d’un camion à température dirigée par exemple. At this point, the transport container (1) is shipped and transported under special conditions, i.e. for a certain time, and being exposed to a transport temperature, which may be room temperature or a temperature. specific temperature of a temperature-controlled truck for example.
Selon l’invention, l’énergie calorifique émise par la charge frigorifique (6) et le coefficient de diffusion thermique de la paroi intercalaire (5) sont ajustés pour permettre la diffusion d’une puissance calorifique à l’intérieur du compartiment, correspondant sensiblement aux besoins réels, pour éviter tout gaspillage de charge frigorifique (6). According to the invention, the heat energy emitted by the refrigeration charge (6) and the thermal diffusion coefficient of the intermediate wall (5) are adjusted to allow the diffusion of a calorific power inside the compartment, substantially corresponding to the real needs, to avoid any waste of refrigeration charge (6).
Pour ce faire, le coefficient de diffusion thermique de la paroi intercalaire (5) peut être ajusté de toute manière appropriée, par exemple, en ajustant la surface (7) de réception de la charge frigorifique (6), ou en modifiant la nature du matériau constituant la paroi intercalaire (5), son épaisseur, ou en réalisant une pluralité de perforations (8), etc... To do this, the thermal diffusion coefficient of the intermediate wall (5) can be adjusted in any suitable manner, for example, by adjusting the surface (7) for receiving the refrigeration charge (6), or by modifying the nature of the material constituting the intermediate wall (5), its thickness, or by making a plurality of perforations (8), etc ...
La puissance calorifique de la charge frigorifique (6) est ajustée en fonction de la quantité et de la nature de la charge frigorifique (6), qui peut être, par exemple, sous forme de bâtonnets, de granulés, de blocs de dioxyde de carbone, de plaques eutectiques à température négative, etc. De préférence, la charge frigorifique (6) est constituée d’une masse de dioxyde de carbone, sous forme de neige sèche ou de glace sèche. The heat output of the refrigeration load (6) is adjusted depending on the amount and nature of the refrigeration load (6), which can be, for example, in the form of sticks, granules, carbon dioxide blocks , eutectic plates at negative temperature, etc. Preferably, the refrigeration charge (6) consists of a mass of carbon dioxide, in the form of dry snow or dry ice.
A titre d’exemple, on cite ci-après différentes charges frigorifiques et leur énergie calorifique par kilogramme : By way of example, we cite below different refrigeration loads and their heat energy per kilogram:
- neige carbonique : 627 KJ/Kg - carbon dioxide snow: 627 KJ / Kg
- Eutectique -3°C : 325 KJ/Kg - Eutectic -3 ° C: 325 KJ / Kg
- Eutectique -21°C : 274 KJ/Kg - Eutectic -21 ° C: 274 KJ / Kg
- Eau (glace hydrique) : 334 KJ/Kg - Water (water ice): 334 KJ / Kg
En pratique, la puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment peut être exprimée comme suit : In practice, the calorific power diffused by the intermediate wall (5) towards the compartment can be expressed as follows:
Avec : With:
Sr : la surface d’échange (7) ; Sr: the exchange surface (7);
lG : la conductivité thermique du matériau de la paroi intercalaire (5) ; lG: the thermal conductivity of the material of the intermediate wall (5);
er : l’épaisseur de la paroi intercalaire (5) ; er: the thickness of the intermediate wall (5);
Trf : la température de changement de phase de la charge frigorifique (6) ; Trf: the phase change temperature of the refrigeration load (6);
Tmaint : la température de maintien à obtenir dans la caisse (2). La puissance calorifique dissipée par la caisse (2) peut être exprimée comme suit : Tmaint: the maintenance temperature to be obtained in the body (2). The calorific power dissipated by the body (2) can be expressed as follows:
Avec : With:
Smb : la surface géométrique (7) de la caisse (2) ; Smb: the geometric surface (7) of the body (2);
Lb : la conductivité thermique du matériau de la caisse (2) ; Lb: the thermal conductivity of the material of the body (2);

Tamb : la température de transport ; Tamb: the transport temperature;
Tmaint : la température de maintien à obtenir dans la caisse (2). Tmaint: the maintenance temperature to be obtained in the body (2).
La puissance calorifique dissipée par la caisse (2) prend en compte la géométrie de la caisse, sa valeur dépendant de sa surface d’échange entre l’extérieur et l’intérieur. The heat dissipated by the body (2) takes into account the geometry of the body, its value depending on its exchange surface between the exterior and the interior.
La conductivité d’un matériau est sa capacité à conduire la chaleur linéairement. La puissance calorifique dissipée par la caisse (2) se qualifie avec la valeur de coefficient de diffusion thermique K en W/m2.°C. Plus cette valeur est élevée, plus il y a de diffusion, moins c’est performant en terme d’isothermie. The conductivity of a material is its ability to conduct heat linearly. The calorific power dissipated by the body (2) is qualified with the value of the thermal diffusion coefficient K in W / m 2. ° C. The higher this value, the more diffusion there is, the less efficient it is in terms of isothermal energy.
A titre d’exemples : For example:
- une caisse (2) présentant une épaisseur de 95mm (9mm de polyéthylène + 86mm de polyuréthane) présente une valeur K= 0.31W/m2.°C. - a box (2) having a thickness of 95mm (9mm of polyethylene + 86mm of polyurethane) has a value of K = 0.31W / m 2. ° C.
- une caisse (2) présentant une épaisseur de 35 mm de polypropylène expansé présente une valeur de K = 0.87 W/m2.°C. - a box (2) having a thickness of 35 mm of expanded polypropylene has a value of K = 0.87 W / m 2. ° C.
La conductivité des matériaux (l) se mesure en W/m2.°C. Les matériaux isolants ont des conductivités comprises entre 0.020 et 0.060W/m2.°C. The conductivity of materials (l) is measured in W / m 2. ° C. Insulating materials have conductivities between 0.020 and 0.060W / m 2. ° C.
Exemples : Examples:
- Polyuréthane : 0.021W/m2.°C - Polyurethane: 0.021W / m 2. ° C
- Polypropylène expansé : 0.038W/m2.°C - Laine de verre : entre 0.030 et 0.040W/m2.°C - Expanded polypropylene: 0.038W / m 2. ° C - Glass wool: between 0.030 and 0.040W / m 2. ° C
- Polystyrène expansé : 0.036W/m2.°C - Expanded polystyrene: 0.036W / m 2. ° C
Selon l’invention, l’énergie calorifique émise par la charge frigorifique (6) et le coefficient de diffusion thermique de la paroi intercalaire (5) sont ajustés pour obtenir : According to the invention, the heat energy emitted by the refrigeration charge (6) and the thermal diffusion coefficient of the intermediate wall (5) are adjusted to obtain:
Pbdiss < Prdif < 1 ,2 x Pbdiss Pbdiss <Prdif <1, 2 x Pbdiss
Le conteneur (1) selon l’invention peut aussi bien pour la conservation de produits surgelés à une température comprise entre -40°C et -18°C, ou de produits frais à une température comprise entre 0°C et 4°C. The container (1) according to the invention can also be used for storing frozen products at a temperature between -40 ° C and -18 ° C, or fresh products at a temperature between 0 ° C and 4 ° C.
Exemple 1 Example 1
A titre d’exemple, pour le transport de produits surgelés à une température de maintien de - 20°C : For example, for the transport of frozen products at a maintenance temperature of - 20 ° C:
La caisse (2) est réalisée en polypropylène expansé délimite un compartiment présentant une surface interne de 0.10 m2. Les parois de la caisse (2) présentent une épaisseur moyenne de 35 mm. The box (2) is made of expanded polypropylene defining a compartment having an internal surface of 0.10 m 2 . The walls of the box (2) have an average thickness of 35 mm.
La puissance calorifique dissipée par l’exemple de caisse (2) en polypropylène expansé décrit ci-dessus, vers l’extérieur à 25°C, est d’environ 28.8 W toutes les heures. Si on souhaite maintenir la température pendant 12h, la puissance dissipée vers l’extérieur sur 12h est de 345, 6W. The heat dissipated by the example of the expanded polypropylene case (2) described above, to the outside at 25 ° C, is approximately 28.8 W every hour. If you want to maintain the temperature for 12 hours, the power dissipated to the outside over 12 hours is 345.6W.
La paroi intercalaire (5) présente une surface (7) de réception en deux zones, chacune ayant une surface d’échange d’environ 499 cm2. La paroi intercalaire (5) est réalisée en polypropylène expansé et présente une épaisseur de 1 cm, perforée de 60 orifices présentant chacun un diamètre d” environ 1 mm. The intermediate wall (5) has a receiving surface (7) in two zones, each having an exchange surface of approximately 499 cm 2 . The intermediate wall (5) is made of expanded polypropylene and has a thickness of 1 cm, perforated with 60 holes each having a diameter of approximately 1 mm.
La paroi intercalaire présente un coefficient de diffusion thermique de 7.8W/m2.°C. Si la chambre reçoit deux plaques de neige carbonique de 203x246x35mm chacune, soit 2kg, émettant une énergie de 1254 KJ, la puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment est égale à 28.8 W toutes les heures, et donc égale à 345, 6W sur 12h. The intermediate wall has a thermal diffusion coefficient of 7.8W / m 2. ° C. If the chamber receives two sheets of carbon dioxide snow of 203x246x35mm each, i.e. 2kg, emitting an energy of 1254 KJ, the heat output diffused by the wall interlayer (5) to the compartment is equal to 28.8 W every hour, and therefore equal to 345.6W over 12h.
La puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment est donc égale à la puissance calorifique dissipée par la caisse pendant une durée de 12h après réception des deux plaques de neige carbonique et exposition du conteneur (1) à une température de transport de 25°C. The calorific power diffused by the intermediate wall (5) towards the compartment is therefore equal to the calorific power dissipated by the body over a period of 12 hours after reception of the two sheets of dry ice and exposure of the container (1) to a transport temperature of 25 ° C.
Pour maintenir les produits surgelés pendant 12h à 25°C, l’épaisseur de la paroi intercalaire (5) en polypropylène expansé pourrait être inférieure à 1cm d’épaisseur de polypropylène. Techniquement, une telle épaisseur n’est pas réalisable par moulage. C’est la raison pour laquelle la paroi intercalaire (5) a été perforée. Une autre solution serait d’agrandir la surface d’échange pour laisser passer le froid. To maintain frozen products for 12 hours at 25 ° C, the thickness of the spacer wall (5) of expanded polypropylene could be less than 1cm of polypropylene thickness. Technically, such a thickness is not achievable by molding. This is the reason why the intermediate wall (5) has been perforated. Another solution would be to enlarge the exchange surface to allow the cold to pass through.
Exemple 2 Example 2
A titre d’exemple, pour le transport de produits frais à une température de maintien de 2°C. For example, for the transport of fresh products at a holding temperature of 2 ° C.
La caisse (2) est réalisée en polypropylène expansé délimite un compartiment présentant une surface interne de 0.10 m2. Les parois de la caisse (2) présentent une épaisseur moyenne de 35 mm. The box (2) is made of expanded polypropylene defining a compartment having an internal surface of 0.10 m 2 . The walls of the box (2) have an average thickness of 35 mm.
La puissance calorifique dissipée par l’exemple de caisse (2) en polypropylène expansé décrit ci-dessus, vers l’extérieur à 25°C, est d’environ 14.7 W toutes les heures. Si on souhaite maintenir la température pendant 12h, la puissance dissipée vers l’extérieur sur 12h est de 176.4W. The calorific power dissipated by the example of the expanded polypropylene box (2) described above, to the outside at 25 ° C, is approximately 14.7 W every hour. If you want to maintain the temperature for 12 hours, the power dissipated to the outside over 12 hours is 176.4W.
La paroi intercalaire (5) présente une surface (7) de réception en deux zones, chacune ayant une surface d’échange d’environ 499 cm2. La paroi intercalaire (5) est réalisée en polypropylène expansé et présente une épaisseur de 2 cm. The intermediate wall (5) has a receiving surface (7) in two zones, each having an exchange surface of approximately 499 cm 2 . The intermediate wall (5) is made of expanded polypropylene and has a thickness of 2 cm.
La paroi intercalaire présente un coefficient de diffusion thermique de 1.85W/m2.°C. Si la chambre reçoit une seule plaque de neige carbonique de 203x246x25mm, soit 0.72kg, émettant une énergie calorifique de 451.44 KJ, la puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment est égale à 14.7 W toutes les heures, et donc égale à 176.4W sur 12h. The intermediate wall has a thermal diffusion coefficient of 1.85W / m 2. ° C. If the chamber receives a single 203x246x25mm dry ice sheet, i.e. 0.72kg, emitting a calorific energy of 451.44 KJ, the calorific power diffused by the intermediate wall (5) towards the compartment is equal to 14.7 W every hour, and therefore equal to 176.4 W over 12 hours.
La puissance calorifique diffusée par la paroi intercalaire (5) vers le compartiment est donc égale à la puissance calorifique dissipée par la caisse pendant une durée de 12h après réception des plaques de neige carbonique et exposition du conteneur (1) à une température de transport de 25°C The calorific power diffused by the intermediate wall (5) towards the compartment is therefore equal to the calorific power dissipated by the body over a period of 12 hours after reception of the dry ice sheets and exposure of the container (1) to a transport temperature of 25 ° C
Pour maintenir des produits frais pendant 12h à 25°C extérieur, la paroi intercalaire (5) en polypropylène expansé doit présenter une épaisseur de 2cm. Si la paroi intercalaire (5) est en polyuréthane, son épaisseur doit être de 1 cm. To keep products fresh for 12 hours at 25 ° C outside, the spacer wall (5) in expanded polypropylene must have a thickness of 2cm. If the intermediate wall (5) is made of polyurethane, its thickness must be 1 cm.
Le couvercle (4) et la paroi intermédiaire (5) comportent des moyens de verrouillage/déverrouillage complémentaires (9) pour se verrouiller l’un sur l’autre et sécuriser ainsi l’accès à la charge frigorifique (6). The cover (4) and the intermediate wall (5) have additional locking / unlocking means (9) to lock onto each other and thus secure access to the refrigeration load (6).
Par exemple, en référence aux figures 5 et 6, les moyens (9) de verrouillage/déverrouillage du couvercle (4) comprennent deux languettes latérales (10), faisant chacune saillie orthogonalement depuis un bord latéral du couvercle (4) et en direction de la paroi intercalaire (5). Chaque languette latérale (10) comporte à son extrémité libre un ergot (11) qui fait saillie vers la languette opposée (10). For example, with reference to Figures 5 and 6, the means (9) for locking / unlocking the cover (4) comprise two side tabs (10), each projecting orthogonally from a side edge of the cover (4) and in the direction of the intermediate wall (5). Each lateral tongue (10) has at its free end a lug (11) which projects towards the opposite tongue (10).
En outre, et en référence aux figures 7 à 9, les moyens de verrouillage/déverrouillage (9) de la paroi intermédiaire (5) comprennent des bords latéraux (12) faisant saillie vers le couvercle (4), et dans lesquels sont ménagées des encoches complémentaires (13) aux languettes latérales (10) et aux ergots (11). In addition, and with reference to Figures 7 to 9, the locking / unlocking means (9) of the intermediate wall (5) comprise lateral edges (12) projecting towards the cover (4), and in which are formed complementary notches (13) to the side tabs (10) and to the lugs (11).
En particulier, le couvercle (4) et la paroi intermédiaire (5) sont destinés à se verrouiller l’un sur l’autre lors d’un mouvement de pivotement du couvercle (4) par rapport à la paroi intercalaire (5) le long d’un bord pivotant (14), et après avoir reçu au moins une charge frigorifique (6). Le couvercle (4) et la paroi intermédiaire (5) sont indépendants l’un de l’autre et comprennent des moyens d’articulation complémentaires (15), capables de permettre au couvercle (4) de pivoter par rapport à la paroi intercalaire (5), afin de permettre à la charge frigorifique (6) d’être chargée dans la chambre. In particular, the cover (4) and the intermediate wall (5) are intended to lock onto each other during a pivoting movement of the cover (4) relative to the intermediate wall (5) along a pivoting edge (14), and after having received at least one refrigeration charge (6). The cover (4) and the intermediate wall (5) are independent of each other and comprise complementary articulation means (15), capable of allowing the cover (4) to pivot relative to the intermediate wall ( 5), in order to allow the refrigeration charge (6) to be loaded into the chamber.
En référence aux figures 5 à 10, les moyens d’articulation (15) du couvercle (4) comportent au moins une rainure (16) disposée le long du bord de pivotement (14) et en regard de la paroi intercalaire (5). Une nervure en saillie (17) à section circulaire borde le côté intérieur de la rainure (16), c’est-à-dire le côté opposé au bord de pivotement (14). La rainure longitudinale (16) ainsi que la nervure en saillie (17) à section circulaire, peuvent être continues sur pratiquement toute la longueur du couvercle (4), ou bien constituées de portions discontinues. Le caractère discontinu de la nervure en saillie (17) permet d’apporter plus de sécurité à l’ensemble. Si l’une des portions de saillie (17) casse, le couvercle (4) peut toujours être utilisé. Par ailleurs, le caractère discontinu permet aussi d’équilibrer la charge sur lesdites nervures (17) et donc d’éviter de solliciter de manière trop importante une seule nervure (17). Referring to Figures 5 to 10, the articulation means (15) of the cover (4) comprise at least one groove (16) disposed along the pivot edge (14) and facing the intermediate wall (5). A protruding rib (17) of circular section borders the inner side of the groove (16), that is to say the side opposite the pivot edge (14). The longitudinal groove (16) as well as the projecting rib (17) of circular section, can be continuous over practically the entire length of the cover (4), or else consist of discontinuous portions. The discontinuous nature of the protruding rib (17) provides more security for the whole. If one of the protruding portions (17) breaks, the cover (4) can still be used. Furthermore, the discontinuous nature also makes it possible to balance the load on said ribs (17) and therefore to avoid placing too much stress on a single rib (17).
En outre, les moyens d’articulation (15) de la paroi intercalaire (5) comprennent au moins une rainure (18) complémentaire à la nervure en saillie (17), destinée à recevoir un engagement de ladite nervure en saillie (17), avec capacité de pivotement. Comme précédemment, la rainure complémentaire (18) de la paroi intercalaire (5) peut être discontinue. In addition, the articulation means (15) of the intermediate wall (5) comprise at least one groove (18) complementary to the projecting rib (17), intended to receive an engagement of said projecting rib (17), with swivel capability. As before, the complementary groove (18) of the intermediate wall (5) can be discontinuous.
Ainsi, en référence à la figure 10, lorsque le couvercle (4) est verrouillé sur la paroi intermédiaire (5), la nervure en saillie (17) à section circulaire est insérée dans la rainure (18) de la paroi intercalaire (5). Thus, with reference to Figure 10, when the cover (4) is locked on the intermediate wall (5), the projecting rib (17) of circular section is inserted into the groove (18) of the intermediate wall (5) .
Cette forme de réalisation des moyens d’articulation complémentaires (15) permet de conserver l’indépendance entre le couvercle (4) et la paroi intercalaire (5), en minimisant les ponts thermiques. En référence à la figure 1 1 , le couvercle (4) peut donc pivoter selon un angle compris entre 10° et 60° par rapport à la paroi intercalaire (5) dans une position d’ouverture pour accéder à la chambre, et permettre le chargement d’au moins une charge frigorifique (6). This embodiment of the complementary articulation means (15) makes it possible to maintain the independence between the cover (4) and the intermediate wall (5), while minimizing thermal bridges. Referring to Figure 1 1, the cover (4) can therefore pivot at an angle between 10 ° and 60 ° relative to the intermediate wall (5) in an open position to access the chamber, and allow the loading of at least one refrigeration charge (6).
Afin de s’adapter à l’application désirée, la surface (7) de réception de la charge frigorifique (6) peut être divisée en deux zones de réception (19) par une languette centraleIn order to adapt to the desired application, the surface (7) receiving the refrigeration charge (6) can be divided into two receiving areas (19) by a central tab
(20) perpendiculaire au bord de pivotement (14). (20) perpendicular to the pivot edge (14).
Dans cette forme de réalisation, et en référence aux figures 5 et 6, les moyens de verrouillage/déverrouillage (9) du couvercle (4) peuvent comprendre deux languettes frontales (21) en saillie orthogonal ement à partir du bord du couvercle (4) opposé au bord de pivotement (14), et en direction de la paroi intercalaire (5). Les deux languettes frontalesIn this embodiment, and with reference to Figures 5 and 6, the locking / unlocking means (9) of the cover (4) may comprise two front tabs (21) projecting orthogonally from the edge of the cover (4) opposite to the pivoting edge (14), and in the direction of the intermediate wall (5). The two front tabs
(21) sont notamment positionnées de part et d’autre de la languette centrale (20), et délimitent entre elles une forme de retenue (22), par exemple en forme de flèche. (21) are in particular positioned on either side of the central tab (20), and define between them a form of retention (22), for example in the form of an arrow.
D’une manière complémentaire, l’extrémité de la languette centrale (20) de la paroi intercalaire (5), en regard de la forme de retenue (22) du couvercle (4), comprend une forme de retenue complémentaire (23) pour se verrouiller entre les deux languettes frontales (21). In a complementary manner, the end of the central tongue (20) of the intermediate wall (5), facing the retaining form (22) of the cover (4), comprises a complementary retaining form (23) for lock between the two front tabs (21).
Avantageusement, en référence aux figures 5, 7 et 9, les extrémités latérales des languettes frontales (21) sont chacune pourvue d’un ergot (24) en saillie destiné à venir s’encliqueter dans des encoches complémentaires (25) aménagées dans les bords (12) de la paroi intercalaire (5). Advantageously, with reference to FIGS. 5, 7 and 9, the lateral ends of the front tongues (21) are each provided with a projecting lug (24) intended to snap into complementary notches (25) provided in the edges (12) of the intermediate wall (5).
Selon l’invention, afin de charger une charge frigorifique (6) entre le couvercle (4) et la paroi intercalaire (5), il convient, à partir d’une paroi intercalaire (5) sur laquelle est posée le couvercle (4) avec capacité de pivotement par rapport à la paroi intercalaire (5) et selon un bord de pivotement (14), de faire pivoter automatiquement le couvercle (4) selon son bord de pivotement (14) d’un angle compris entre 10° et 60°, et de pousser automatiquement au moins une charge frigorifique (6) à l’intérieur de la chambre. According to the invention, in order to charge a refrigeration charge (6) between the cover (4) and the intermediate wall (5), it is appropriate, from an intermediate wall (5) on which the lid (4) is placed with pivoting capacity relative to the intermediate wall (5) and along a pivoting edge (14), to automatically rotate the cover (4) according to its pivoting edge (14) by an angle between 10 ° and 60 °, and automatically push at least one refrigerating charge (6) inside the chamber.
Pour ce faire, l’invention concerne également une installation (26) comprenant des moyens support (27) de paroi intercalaire (5) sur laquelle est posé le couvercle (4), et des moyens de pivotement (28) du couvercle (4), par exemple sous la forme d’un vérin apte à soulever le bord frontal du couvercle (4). To do this, the invention also relates to an installation (26) comprising support means (27) for an intermediate wall (5) on which the cover (4) is placed, and pivoting means (28) of the cover (4), for example in the form of a jack capable of lifting the front edge of the cover (4).
A partir de ce principe, plusieurs formes de réalisions sont possibles. Il est possible de mettre en œuvre une installation sous la forme d’une installation linéaire, telle qu’illustrée à la figure 13, ou par exemple une station individuelle, telle qu’illustrée aux figures 14 à 16 From this principle, several forms of realization are possible. It is possible to implement an installation in the form of a linear installation, as illustrated in figure 13, or for example an individual station, as illustrated in figures 14 to 16
En référence à la figure 13, les moyens support (27) peuvent se présenter sous la forme d’un convoyeur apte à faire défiler la paroi intercalaire (5) sur laquelle est posé le couvercle (4). Dans cette configuration, les moyens de pivotement (28) du couvercle (4) sont positionnés sur le chemin de défilement du couvercle (4). Referring to Figure 13, the support means (27) may be in the form of a conveyor capable of scrolling the intermediate wall (5) on which the cover (4) is placed. In this configuration, the pivoting means (28) of the cover (4) are positioned on the travel path of the cover (4).
En référence à la figure 12, l’installation (26) comprend également des moyens d’approvisionnement (29) d’une charge frigorifique (6). De préférence, la charge frigorifique (6) se présente sous la forme d’un bloc de neige ou de glace carbonique, et les moyens d’approvisionnement (29) sont combinés avec des moyens de génération (30) de la neige ou de la glace carbonique. Ces moyens de génération (30) permettent de générer un bloc de neige ou de glace carbonique, qui est ensuite coupé en tranches, et les tranches sont poussées, par exemple par des vérins, dans la chambre entre le couvercle (4) et la paroi intercalaire (5). Referring to Figure 12, the installation (26) also includes means (29) for supplying a refrigeration charge (6). Preferably, the refrigeration charge (6) is in the form of a block of snow or dry ice, and the supply means (29) are combined with means (30) for generating snow or ice. dry ice. These generation means (30) make it possible to generate a block of snow or dry ice, which is then cut into slices, and the slices are pushed, for example by jacks, into the chamber between the cover (4) and the wall. interlayer (5).
En référence à l’installation (26) illustrée sur la figure 13, après avoir été soulevé par le vérin, le couvercle (4) est déplacé par l’intermédiaire du convoyeur, toujours en position ouverte et en appui sur une barre d’appui (31) et de maintien en position ouverte. Les moyens d’approvisionnement (29) ne sont pas représentés sur la figure 13, mais ils sont en pratique positionnés en face de la barre d’appui (31). With reference to the installation (26) illustrated in Figure 13, after having been lifted by the jack, the cover (4) is moved by means of the conveyor, still in the open position and resting on a support bar (31) and kept in the open position. The supply means (29) are not shown in Figure 13, but they are in practice positioned in front of the support bar (31).
L’installation (26) comprend ensuite des moyens de fermeture (32) automatique du couvercle (4) sur la paroi intercalaire (5) pour leur verrouillage l’un avec l’autre après réception de la charge frigorifique (6). Ces moyens (32) se présentent, par exemple, sous la forme d’un vérin apte à appuyer sur le dessus du couvercle (4) pour engager les différents moyens de verrouillage/déverrouillage complémentaires (9). Le procédé comprend avantageusement une étape consistant à contrôler automatiquement le chargement de la charge frigorifique (6) entre le couvercle (4) et la paroi intercalaire (5) de sorte que, en cas de non chargement ou de déchargement partiel, le couvercle (4) et la paroi intercalaire (5) sont envoyés vers un poste de rebut ou de correction (non représenté) et, en cas de changement total, le couvercle (4) et la paroi intercalaire (5) sont envoyés vers un poste de fermeture ou un poste final (non représenté) en vue de leur positionnement sur une caisse (2). The installation (26) then comprises means (32) for automatically closing the cover (4) on the intermediate wall (5) for their locking with one another after reception of the refrigeration charge (6). These means (32) are, for example, in the form of a jack capable of pressing on the top of the cover (4) to engage the various complementary locking / unlocking means (9). The method advantageously comprises a step consisting in automatically controlling the loading of the refrigeration charge (6) between the cover (4) and the intermediate wall (5) so that, in the event of no loading or partial unloading, the cover (4) ) and the intermediate wall (5) are sent to a scrap or correction station (not shown) and, in the event of a total change, the cover (4) and the intermediate wall (5) are sent to a closing station or an end station (not shown) for their positioning on a box (2).
Sur l’installation (26) illustrée à la figure 13, l’étape consistant à contrôler le changement de la charge frigorifique (6) s’effectue après la fermeture du couvercle (4). On the installation (26) shown in Figure 13, the step of controlling the change in the refrigeration charge (6) takes place after closing the cover (4).
Pour ce faire, l’installation (26) comprend dans une forme de réalisation particulière une balance (33) positionnée avant ou après les moyens de fermeture (32) du couvercle (4), pour vérifier le poids du couvercle (4) et de la paroi intercalaire (5) chargés en charge frigorifique (6). Si le poids ne correspond pas, un vérin (34) est apte à pousser latéralement le couvercle (4) et la paroi intercalaire (5) vers le poste de rebut ou de correction. Si le poids est correct, le couvercle (4) et la paroi intercalaire (5) défilent vers un autre vérin (35) destiné à pousser latéralement le couvercle (4) et la paroi intercalaire (5) vers un poste final, en vue du positionnement dudit couvercle (4) et de la paroi intercalaire (5) sur une caisse (2) d’un conteneur (1) comprenant des produits à maintenir en température. To do this, the installation (26) comprises in a particular embodiment a scale (33) positioned before or after the closing means (32) of the cover (4), to check the weight of the cover (4) and of the intermediate wall (5) loaded with refrigeration charge (6). If the weight does not correspond, a jack (34) is able to laterally push the cover (4) and the intermediate wall (5) towards the waste or correction station. If the weight is correct, the cover (4) and the intermediate wall (5) move towards another cylinder (35) intended to push the cover (4) and the intermediate wall (5) laterally towards an end station, with a view to positioning of said cover (4) and of the intermediate wall (5) on a box (2) of a container (1) comprising products to be maintained at temperature.
En référence aux figures 14 à 16 illustrant la station individuelle, celle-ci comprend des moyens support (27) sous la forme d’un plan de travail sur lequel un opérateur vient positionner la paroi intercalaire (5) et le couvercle (4). Des taquets en demi-lune (36), actionnés par un système de vérin (37) font saillie du plan de travail pour venir verrouiller en butée et en position la paroi intercalaire (5) et le couvercle (4), ou sont escamotés pour libérer la paroi intercalaire (5) et le couvercle (4). Des moyens de plaquage (38), tels qu’un système de ventouses positionnées sous le plan de travail et assujetties à un vérin (39) viennent plaquer la paroi intercalaire (5) contre le plan de travail pour permettre le pivotement du couvercle (4) sans déplacer la paroi intercalaire (5). Lorsque la paroi intercalaire (5) et le couvercle (4) sont positionnés sur les moyens support (27), le couvercle se retrouve positionné sous une plaque d’appui (40) prolongée latéralement par deux rebords (41) repliés sous les bords latéraux du couvercle (4). Cette plaque d’appui (40) est reliée de manière articulée à un vérin (42) de sorte que l’actionnement du vérin (42) permet de relever la plaque d’appui (40), emportant par l’intermédiaire des bords (41) repliés, le pivotement du couvercle (40). L’articulation entre le vérin (42) et la plaque d’appui (40) permet de faire pivoter le couvercle (40). Referring to Figures 14 to 16 illustrating the individual station, the latter comprises support means (27) in the form of a work surface on which an operator positions the intermediate wall (5) and the cover (4). Half-moon cleats (36), actuated by a cylinder system (37) protrude from the worktop to lock the intermediate wall (5) and the cover (4) in abutment and in position, or are retracted to release the intermediate wall (5) and the cover (4). Plating means (38), such as a system of suction cups positioned under the worktop and secured to a jack (39) press the intermediate wall (5) against the worktop to allow the cover (4) to pivot. ) without moving the intermediate wall (5). When the intermediate wall (5) and the cover (4) are positioned on the support means (27), the cover is found positioned under a support plate (40) extended laterally by two flanges (41) folded under the lateral edges cover (4). This support plate (40) is hingedly connected to a jack (42) so that the actuation of the jack (42) makes it possible to raise the support plate (40), carrying via the edges ( 41) folded, the pivoting of the cover (40). The articulation between the cylinder (42) and the support plate (40) allows the cover (40) to pivot.
Une fois le couvercle (4) ouvert, les moyens d’approvisionnement (29), non représentés sur les figures 14 à 16, poussent au moins une plaque de neige dans la chambre du couvercle (4). Once the cover (4) is open, the supply means (29), not shown in Figures 14 to 16, push at least one patch of snow into the chamber of the cover (4).
Ensuite, l’actionnement du vérin (42) dans le sens inverse permet d’appuyer, par l’intermédiaire de la plaque d’appui (40) sur le couvercle (4) pour le verrouiller sur la paroi intercalaire (5). Le guidage de la plaque d’appui (40) est réalisé latéralement par un système de crémaillère (43). Then, the actuation of the cylinder (42) in the opposite direction makes it possible to press, through the support plate (40) on the cover (4) to lock it on the intermediate wall (5). The support plate (40) is guided laterally by a rack system (43).
Bien entendu, le plan de travail de la station individuelle peut intégrer une balance pour contrôler le poids de la charge frigorifique (6). Of course, the worktop of the individual station can integrate a scale to control the weight of the refrigeration load (6).
