DISPOSITIF D'ETANCHEITE D'UN SYSTEME DE REFROIDISSEMENT La présente invention concerne un dispositif d'étanchéité d'un système de refroidissement, de réchauffage ou de maintien de température de produits. L'invention concerne également un tel dispositif comprenant au moins un groupe de produits, notamment placés sur une palette. The present invention relates to a sealing device for a system for cooling, reheating or maintaining the temperature of products. BACKGROUND OF THE INVENTION The invention also relates to such a device comprising at least one group of products, in particular placed on a pallet.
La demanderesse a proposé, dans le document WO-99/11141 un dispositif d'étanchéité pour cellule de maintien en température de produits placés sur palette. The applicant has proposed, in the document WO-99/11141, a sealing device for a product temperature holding cell placed on a pallet.
On connaît une grande variété de palettes: double face à deux entrées, palette à chevrons simple face, palette à quatre entrées à dés ou à chevrons, palettes à chevrons ou à dés réversibles, rivetées, clouées, demi palettes à quatre entrées... A wide variety of pallets are known: two-sided double-sided pallet, single-sided pallet pallet, pallet with four dice or chevron entries, herringbone or reversible pallets, riveted, nailed, half pallets with four entries ...
Il existe une tendance à la normalisation, notamment européenne, pour les palettes: palette EUR 120x80. Il existe aussi des habitudes par secteur industriel. Par exemple, dans le hard discount (maxidiscompte) en Allemagne ou/et France, les palettes Dusseldôrfer 600x800 mm sont répandues. There is a trend towards standardization, especially European, for pallets: pallet EUR 120x80. There are also habits by industry sector. For example, in hard discount in Germany and / or France, Dusseldorfer pallets 600x800 mm are widespread.
La normalisation tend à uniformiser les largeurs et longueurs de palettes. Toutefois, les hauteurs de palettes restent variables: 172 mm pour I'EUR 80.120, 163mm pour une Dusselddrfer par exemple. La hauteur de palette varie également par l'emploi de planches d'épaisseur différentes entre palette légère, demi lourde et lourde. Standardization tends to standardize widths and lengths of pallets. However, the pallet heights remain variable: 172 mm for EUR 80.120, 163 mm for a Dusseldrfer for example. The pallet height also varies by the use of boards of different thickness between light pallet, half heavy and heavy.
Lorsqu'un dispositif tel que décrit dans le document WO-99/11141 de la demanderesse est utilisé, l'étanchéité est assurée notamment par le contact entre la bâche souple supérieure et le dessus des produits palettisés. Si des palettes de hauteur très différentes sont utilisées, il est à craindre que l'étanchéité ne soit pas maintenue à un niveau optimum dans tous les cas. Ce problème est bien entendu aggravé si la hauteur des produits palettisés est trop variable. When a device as described in the document WO-99/11141 of the applicant is used, sealing is provided in particular by the contact between the upper flexible sheet and the top of the palletized products. If very different pallets of height are used, it is to be feared that the seal is not maintained at an optimum level in all cases. This problem is of course aggravated if the height of the palletized products is too variable.
L'invention vise à pallier ces inconvénients. The invention aims to overcome these disadvantages.
2871222 2 A cette fin, l'invention se rapporte, selon un premier aspect, à un dispositif d'étanchéité dans un tunnel de ventilation de produits, comprenant au moins une bâche venant se plaquer contre une face desdits produits, sous l'effet de la pression d'air de ventilation circulant de manière forcée entre ladite bâche et une paroi du tunnel placée en regard, la bâche étant pourvue à sa rive amont d'un moyen de rappel tel que contrepoids ou moyen tendeur et étant montée glissante, entre sa rive amont et sa rive aval, contre une barre de renvoi tournante. To this end, the invention relates, according to a first aspect, to a sealing device in a product ventilation tunnel, comprising at least one tarpaulin being pressed against one side of said products, under the effect of the pressure of ventilation air circulating forcibly between said tarpaulin and a wall of the tunnel placed opposite, the sheet being provided at its upstream bank with a return means such as counterweight or tensioning means and being mounted slippery, between its upstream bank and its downstream bank, against a rotating return bar.
Dans une réalisation, une barre mobile est fixée à ladite bâche, à proximité de sa rive aval, cette barre étant montée dans un fourreau permettant son entraînement, à la mise en service du système, sa course étant limitée par butée de sorte à s'opposer au déplacement de la bâche, au droit d'un espace délimité par ladite face des produits et ladite paroi du tunnel. In one embodiment, a movable bar is fixed to said tarpaulin, near its downstream side, this bar being mounted in a sleeve allowing its driving, at the commissioning of the system, its stroke being limited by abutment so that to oppose the displacement of the cover, to the right of a space delimited by said face of the products and said wall of the tunnel.
D'autres objets et avantages de l'invention apparaîtront au cours de la description suivante de modes de réalisation, description qui va être effectuée en se référant aux dessins annexés dans lesquels: - la figure 1 est une vue en perspective d'un dispositif selon un mode de réalisation de l'invention, représenté en position de chargement/ déchargement d'une palette de produits; la figure 2 est une vue en perspective du dispositif de la figure 1, lors de la ventilation de la palette de produits; la figure 3 est une vue de détail d'une partie de la figure 2. Other objects and advantages of the invention will become apparent from the following description of embodiments, a description which will be made with reference to the accompanying drawings in which: - Figure 1 is a perspective view of a device according to an embodiment of the invention, shown in the loading / unloading position of a pallet of products; Figure 2 is a perspective view of the device of Figure 1, during the ventilation of the product pallet; FIG. 3 is a detail view of part of FIG. 2.
Les éléments communs avec le dispositif décrit dans le document WO 99/11141 ne sont pas présentés à nouveau ici. The elements common with the device described in WO 99/11141 are not presented again here.
Ainsi qu'il apparaît sur les figures annexées, la bâche supérieure 1 s'étend entre un contrepoids 2 et une barre de fixation 3. As it appears in the appended figures, the upper sheet 1 extends between a counterweight 2 and a fixing bar 3.
Le contrepoids 2 est avantageusement une barre placée dans un ourlet de la bâche supérieure 1. Le montage du contrepoids 2 est ainsi facile et rapide, et l'utilisateur peut choisir la masse du contrepoids adaptée aux conditions de fonctionnement, notamment en fonction de la puissance de ventilation. The counterweight 2 is advantageously a bar placed in a hem of the upper cover 1. The mounting of the counterweight 2 is thus easy and fast, and the user can choose the weight of the counterweight adapted to the operating conditions, in particular according to the power ventilation.
2871222 3 Le cas échéant, la bâche est pourvue de plusieurs ourlets, permettant de placer plusieurs barres de contrepoids et/ou de choisir la zone de mouvement de ces contrepoids. 2871222 3 Where applicable, the sheet is provided with several hems, allowing to place several counterweight bars and / or to choose the movement zone of these counterweights.
La barre de fixation est avantageusement sensiblement de même section 5 et forme qu'une barre de contrepoids et est placée dans un ourlet de la bâche supérieure 1. Le montage de la bâche est ainsi facilité. The fixing bar is advantageously substantially the same section 5 and forms a counterweight bar and is placed in a hem of the top cover 1. The mounting of the cover is thus facilitated.
Une barre de renvoi 4 et une barre mobile 5 sensiblement parallèles entre elles sont placées contre la bâche supérieure 1, entre la barre de fixation 3 et le contrepoids 2. A return bar 4 and a movable bar 5 substantially parallel to each other are placed against the upper sheet 1, between the fixing bar 3 and the counterweight 2.
La barre de renvoi 4 est montée tournante à une paroi latérale 6 du dispositif et la bâche supérieure 1 peut glisser sur cette barre de renvoi, le mouvement de glissement de la bâche supérieure 1 étant lié à la modification de l'équilibre des forces entre le poids du contrepoids 2 et la pression de ventilation, pression figurée par les flèches 7. The deflection bar 4 is rotatably mounted to a side wall 6 of the device and the upper cover 1 can slide on this deflection bar, the sliding movement of the upper cover 1 being related to the modification of the balance of forces between the weight of the counterweight 2 and the pressure of ventilation, pressure shown by the arrows 7.
En position de chargement/déchargement, représentée en figure 1, le contrepoids 2 assure la tension de la bâche supérieure 1 et la barre mobile 5 se trouve dans une position de repos. In the loading / unloading position, shown in FIG. 1, the counterweight 2 ensures the tension of the upper tarpaulin 1 and the movable bar 5 is in a rest position.
En position de ventilation, représentée en figure 2, la pression d'air 7 contre la bâche supérieure 1 vient gonfler cette bâche pour la plaquer contre la face supérieure 8 des produits 9 placés sur la palette 10, la barre mobile 5 étant dans une deuxième position. Le cas échéant, un ressort, par exemple de torsion, ou tout autre moyen élastique, est logé dans l'articulationll en rotation de la barre mobile 5. In the ventilation position, shown in FIG. 2, the air pressure 7 against the upper cover 1 inflates this cover to press against the upper face 8 of the products 9 placed on the pallet 10, the movable bar 5 being in a second position. position. If necessary, a spring, for example torsion, or any other elastic means, is housed in the articulationll in rotation of the movable bar 5.
La barre mobile 5 permet de bloquer le mouvement de la bâche 25 supérieure 1 vers l'avant du dispositif. Cette barre 5 est incorporée dans le fourreau 12 de la bâche 1. The movable bar 5 makes it possible to block the movement of the upper tarpaulin 1 towards the front of the device. This bar 5 is incorporated in the sheath 12 of the sheet 1.
La course de la barre mobile 5 est limitée par une butée 15. The stroke of the movable bar 5 is limited by a stop 15.
Le système qui vient d'être décrit peut être transposé pour le maintien de l'étanchéité sur les parois latérales du dispositif, le contrepoids étant remplacé par une moyen tendeur élastique fixé entre le bord 13 d'une bâche latérale et une paroi, par exemple arrière 14, du dispositif. Le système peut 2871222 4 ainsi maintenir une bonne étanchéité lors de la ventilation des produits palettisés, ceci pour une gamme étendue de largeurs de palettes et/ou de hauteur d'empilement de produits. The system which has just been described can be transposed to maintain the seal on the side walls of the device, the counterweight being replaced by an elastic tensioning means fixed between the edge 13 of a side cover and a wall, for example rear 14 of the device. The system can thus maintain a good seal during the ventilation of the palletized products, this for a wide range of pallet widths and / or product stacking height.
Il est entendu que, pour des raisons industrielles, le dispositif est particulièrement adapté à des charges palettisées, mais qu'il peut également être mis en oeuvre pour des charges reposant sur d'autres supports que des palettes, voire pour des charges reposant directement au sol. It is understood that, for industrial reasons, the device is particularly suitable for palletised loads, but it can also be used for loads resting on supports other than pallets, or even for loads resting directly on the palletized loads. ground.
