- these pallets may be of variable length and width, the height of the assembly formed by the products on the pallet may also vary considerably and in particular, it will be possible to enter the temperature treatment installation following the pallets whole and half pallets.
- these installations comprise at least one chamber, means for introducing a pallet and means for conveying the pallet, these conveying means being able to be made in particular by conveyor belts.
- These installations also include air blowing means for passing air through the pallets in particular to heat, cool or maintain the temperature at the pallets.
- the air blowing means consist of fans creating a movement of air, these fans cooperating with batteries for heating or cooling the air.
- blowing means alternately blowing from one chamber to another and, for example, from the left towards the right in relation to the conveying direction of the pallets in one chamber and from the right to the left in another chamber.
- An installation according to the preamble of claim 1 is known for example from the document DE-A1-100 17 408 .
- the processing facilities on the market have great advantages, including the ability to process pallets continuously.
- this tarpaulin or wall system is not easy to set up since, before any treatment of a series of pallets, it is it is necessary to manually adjust the height of this tarpaulin to the maximum foreseeable height of the pallets to enter the installation.
- the present invention aims to overcome the aforementioned drawbacks and to provide a product temperature treatment facility for limiting the "by-pass" of the air and therefore, to increase the energy efficiency of the installation.
- Another object of the present invention is to provide a product temperature processing facility arranged in pallets to remove and / or significantly limit the free space between each pallet and the ceiling of the installation.
- Another object of the present invention is to provide a temperature treatment facility for products that can process pallets of very variable height in the same series and for example, both full pallets and half pallets.
- the invention thus relates to a product temperature treatment facility arranged in a pallet or the like said installation having the technical features of claim 1.
- This installation 1 comprises means for introducing a pallet, these means not being shown in the accompanying drawings but are widely known to those skilled in the art.
- the installation 1 further comprises conveying means 5 of the pallet between an inlet and an outlet of the installation 1 as well as air blowing means 6 through the products 2 of the pallet 3.
- the installation 1 further comprises longitudinal separation means 7 liftable.
- These separation means 7 are arranged substantially in the main axis of said at least one chamber and make it possible to prevent the flow of air between the upper surface 8 of each pallet 3 and the ceiling 9 of said at least one chamber 4. .
- these longitudinal separation means 7 will occupy the entire length of the chamber 4 and longitudinal separation means 7 will be provided at each chamber 4.
- the longitudinal separation means 7 comprise displacement means 10 allowing the positioning of flexible elements 11 ensuring the seal between the ceiling 9 and the upper surface 8 of each pallet 3.
- the displacement means 10 allow the recovery or the placement of these flexible elements 11.
- the flexible elements 11 are distributed in two rows. This arrangement is particularly favorable if blowing means are provided on each side of the pallets 3 or to provide a surface with increased sealing.
- the displacement means 10 comprise two inner tubes 12 and outer 13, the outer tube 13 carrying the flexible elements 11 and the inner tube 12 carrying a latch 14 whose raising causes the rotation of the outer tube 13 and the bearing of the flexible elements 11.
- the flexible elements 11 may consist in particular of bristles such as represented in particular in the figure 4 .
- the bristles constituting the flexible elements 11 are independent of one another. This feature allows once the establishment of these flexible elements 11 to remove the free space between the ceiling 9 and each upper surface 8 of each pallet. Each flexible element 11 is indeed stopped only when its end touches the upper surface 8 of the pallet.
- these flexible elements 11 are interconnected in their upper part forming a completely airtight curtain.
- This upper part has a positioning such that its lower end is always above the upper surface 8 of the highest pallet 3 provided in the chamber 4.
- these longitudinal separation means 7 also comprise control means 15 for driving the displacement means 10, these control means 15 being in particular made by a jack.
- the lifting means 10 of the flexible elements 11 are preferably automatically raised.

- the longitudinal separation means 7 comprise a drive shaft 20 equipped with retaining means 21 and allowing the driving of articulated arms 22 in the upward direction as illustrated in FIG. figure 5 .
- the longitudinal separation means 7 also comprise at least one sealing sheet 23 connected to the articulated arms 22.
- the retaining means 21 comprise a cleat 24 disposed on the drive shaft 20, each cleat cooperating with a so-called proximal end of an articulated arm 22.
- the arm 22 has articulations, the articulation being positioned so that a part of lower rank 22 'of the articulated arm 22 can be raised with respect to a part of higher rank namely 22 "which itself can be raised compared to the part 22"'.
- This feature is particularly interesting since it allows, when the drive shaft 20 lowers the arms 22 towards the products that the force exerted by the cover 23 on the products is distributed on the underside of the distal end 26 articulated arm 22.
- articulated arms which are all independent of each other also makes it possible to recover the level deviations on the pallets; in fact, during the descent of the articulated arms 22, the cleats 24 hold the arms 22 until they stop on the pallet then continue the rotation leaving the arm 22 in its place at the end of the descent, at the end of the rotation of the shaft 20, the set of arms 22 have their distal end 26 in contact with the palletized product.
- articulated arms 22 may be used.
- FIGS. Figures 9a, 9b and 9c articulated arms 22 having one, two or three articulations may be used.
- the dimensioning or also the spacing between the articulated arms 22 may be variable and in particular, the articulated arms may be spaced from 20 to 100 cm on said drive shaft 20.
- control means 27 comprising a jack.
- control means may also be considered.
- the arms 22 are connected to the cover 23 which, advantageously, comprises pockets 30 allowing the introduction of the articulated arms 22.
- connection between the arms 22 and the sealing sheet 23 is removable.
- the securing in the pockets 30 is fixed or that the arms 22 are not fixed in pockets 30 but on one side of the sealing cover 23.
- bellows 28 are provided at the level of the sealing sheet 28 between the pockets 30.
- these bellows 28 will have a flared shape in the direction of the lower end 29 of the cover 23.
- This feature makes it possible to allow the placement of two adjacent articulated arms 22 at different heights and in particular, with height differences of 20 cm and 1 m, thus making it possible to seal the upper part of the installation even when the pallets have significant differences in height.
- additional separation means 16 disposed substantially perpendicularly and at the ends of the longitudinal separation means 7 and for preventing the flow of air between two chambers 4 at the upper parts.
- Additional separation means 16 comprise additional displacement means 17 and a guillotine 18, the additional displacement means 17 allowing a displacement in translation of the guillotine 18 between a lowered working position and a raised position.
- the additional displacement means 17 are synchronized with the displacement means 10 of the flexible elements 11.
- the association between the longitudinal separation means 7 and the additional separation means 16 ensures a good seal of all the upper parts, that is to say parts located above the upper surface 8 of the pallets 3.
- the treatment plant thus equipped is therefore particularly efficient since the air leaving the blowing means 6 is necessarily forced through the pallet 3.
- the pallets 3 are introduced into the installation 1 so as to be aligned on one side having in what way a reference surface.
- the side opposite the aligned side has offsets and therefore a space through which the air can escape.
- the lateral sealing means 19 make it possible to fill this space and in particular advantageously at the ends of the chambers 4.
- These sealing means 19 may comprise sliding doors 20 disposed substantially perpendicular to the main axis of each chamber 4.

Abstract
Description
La présente invention concerne une installation de traitement en température de produits disposés en palette ou similaire.The present invention relates to an installation for the temperature treatment of products arranged in a pallet or the like.
La présente invention trouvera son application principale dans la réalisation d'installation de traitement en vue du refroidissement ou du maintien en température de produits et plus particulièrement de produits dans le domaine agro-alimentaire.The present invention will find its main application in the production of treatment plant for the cooling or temperature maintenance of products and more particularly of products in the agri-food field.
Toutefois, bien que particulièrement prévue pour une telle application, l'installation de traitement pourra également être utilisée pour d'autres applications et notamment, le réchauffement de produits dans le domaine alimentaire ou encore dans bien d'autres domaines.However, although particularly intended for such an application, the treatment facility may also be used for other applications and in particular, the heating of products in the food field or in many other areas.
Par palette ou similaire, il faudra entendre dans le reste de la demande tout type de support permettant le stockage et la manipulation de produits notamment empilés. Il pourra s'agir à titre d'exemple de palettes double faces à deux entrées, palettes à chevrons simple face, palettes à quatre entrées à dés ou à chevrons, palettes à chevrons ou à dés réversibles, rivetées, clouées, demi palettes à quatre entrées.By pallet or the like, it will be understood in the rest of the application any type of support for storing and handling products including stacked. Examples include double-sided double-sided pallets, single-sided herringbone pallets, four-sided or herringbone pallets, herringbone or reversible pallets, riveted, nailed, half pallets with four entries.
Bien entendu, ces palettes pourront être de longueur et de largeur variables, la hauteur de l'ensemble formé par les produits sur la palette pouvant également varier considérablement et notamment, on pourra rentrer dans l'installation de traitement en température à la suite des palettes entières et des demi palettes.Of course, these pallets may be of variable length and width, the height of the assembly formed by the products on the pallet may also vary considerably and in particular, it will be possible to enter the temperature treatment installation following the pallets whole and half pallets.
On connaît déjà sur le marché des installations de traitement en température de produits disposés en palettes.Already known on the market facilities for temperature treatment of products arranged in pallets.
Généralement, ces installations comportent au moins une chambre, des moyens d'introduction d'une palette et des moyens de convoyage de la palette, ces moyens de convoyage pouvant être réalisés notamment par des bandes transporteuses.Generally, these installations comprise at least one chamber, means for introducing a pallet and means for conveying the pallet, these conveying means being able to be made in particular by conveyor belts.
Ces installations comportent également des moyens de soufflage d'air permettant de faire passer l'air à travers les palettes en vue notamment de réchauffer, refroidir ou encore maintenir la température au niveau des palettes.These installations also include air blowing means for passing air through the pallets in particular to heat, cool or maintain the temperature at the pallets.
Classiquement, les moyens de soufflage d'air sont constitués de ventilateurs créant un mouvement d'air, ces ventilateurs coopérant avec des batteries permettant de réchauffer ou de refroidir cet air.Conventionally, the air blowing means consist of fans creating a movement of air, these fans cooperating with batteries for heating or cooling the air.
Dans certaines installations, pour permettre de refroidir de manière homogène la palette qui traverse l'installation, on prévoit plusieurs chambres avec des moyens de soufflage soufflant d'une manière alternée d'une chambre à une autre et, par exemple, de la gauche vers la droite par rapport au sens de convoyage des palettes dans une chambre et de la droite vers la gauche dans une autre chambre. Une installation conforme au préambule de la revendication 1 est connue par exemple du document
Les installations de traitement sur le marché présentent de grands avantages et notamment de pouvoir traiter des palettes en continu.The processing facilities on the market have great advantages, including the ability to process pallets continuously.
Toutefois, les installations présentent différents inconvénients parmi lesquels la difficulté de contrôler et d'ajuster de manière fine la température des produits sur les palettes.However, the installations have various drawbacks among which the difficulty of controlling and fine-tuning the temperature of the products on the pallets.
Par ailleurs, un autre inconvénient de ce type d'installations de traitement réside dans la mauvaise canalisation de l'air dans l'installation.Moreover, another disadvantage of this type of treatment facilities lies in the poor channelization of the air in the installation.
En effet, pour que l'installation soit efficace, il faut qu'un maximum d'air traverse les produits de manière à obtenir un bon échange thermique. Or, compte tenu de l'espace libre entre le haut des palettes et le plafond de l'installation, une grande partie de l'air passe par au dessus des palettes, ce qui diminue les capacités de refroidissement de l'installation.Indeed, for the installation to be effective, it is necessary that a maximum of air passes through the products so as to obtain a good heat exchange. However, given the free space between the top of the pallets and the ceiling of the installation, a large part of the air passes over the pallets, which decreases the cooling capacity of the installation.
Pour remédier à ces inconvénients, il a été proposé des bâches fixes disposées entre le plafond de l'installation et le haut des palettes ; toutefois, cette solution n'est pas satisfaisante car la bâche, rigide, peut endommager les produits sur les palettes et notamment, lorsque ces palettes sont déplacées, entraîner la chute des produits.To overcome these disadvantages, it has been proposed fixed tarpaulins arranged between the ceiling of the installation and the top of the pallets; however, this solution is not satisfactory because the tarpaulin, rigid, can damage the products on the pallets and in particular, when these pallets are moved, cause the fall of the products.
Il a également été proposé dans la demande de bvevet allemand
Il est également important de souligner que ce système de bâche ou paroi est peu aisé à mettre en place puisque, avant tout traitement d'une série de palettes, il est nécessaire de régler manuellement la hauteur de cette bâche sur la hauteur maximale prévisible des palettes devant entrer dans l'installation.It is also important to emphasize that this tarpaulin or wall system is not easy to set up since, before any treatment of a series of pallets, it is it is necessary to manually adjust the height of this tarpaulin to the maximum foreseeable height of the pallets to enter the installation.
Enfin, un autre inconvénient de ces installations classiquement utilisées est l'absence d'étanchéité entre les chambres elles-mêmes, ce qui est particulièrement préjudiciable lorsque les moyens de soufflage de chaque chambre sont opposés puisqu'il se crée dans une chambre une dépression là où dans la chambre opposée on retrouve une surpression, ce qui entraîne l'air d'une chambre directement dans !a deuxième chambre, cet air ne traversant par conséquent pas les palettes et n'étant donc pas utile.Finally, another disadvantage of these facilities conventionally used is the lack of tightness between the chambers themselves, which is particularly detrimental when the blowing means of each chamber are opposite since it is created in a room a depression there where in the opposite chamber there is an overpressure, which causes the air of a chamber directly in the second chamber, the air therefore not passing through the pallets and therefore not useful.
Compte tenu de ces inconvénients, les installations de traitement actuellement sur le marché ont un rendement énergétique faible et ne permettent pas de régler de manière satisfaisante la température des produits disposés sur les palettes.In view of these drawbacks, the treatment plants currently on the market have a low energy efficiency and do not make it possible to satisfactorily regulate the temperature of the products arranged on the pallets.
La présente invention a pour but de pallier aux inconvénients précités et de proposer une installation de traitement en température de produits permettant de limiter les « by-pass » de l'air et par conséquent, d'augmenter le rendement énergétique de l'installation.The present invention aims to overcome the aforementioned drawbacks and to provide a product temperature treatment facility for limiting the "by-pass" of the air and therefore, to increase the energy efficiency of the installation.
Un autre but de la présente invention est de proposer une installation de traitement en température de produits disposés en palettes permettant de supprimer et/ou de limiter considérablement l'espace libre entre chaque palette et le plafond de l'installation.Another object of the present invention is to provide a product temperature processing facility arranged in pallets to remove and / or significantly limit the free space between each pallet and the ceiling of the installation.
Un autre but de la présente invention est de proposer une installation de traitement en température de produits pouvant traiter des palettes de hauteur très variable dans une même série et par exemple, à la fois des palettes entières et des demi palettes.Another object of the present invention is to provide a temperature treatment facility for products that can process pallets of very variable height in the same series and for example, both full pallets and half pallets.
L'invention a ainsi pour objet une installation de traitement en température de produits disposés en palette ou similaire ladite installation présentant les caractéristiques techniques de la revendication 1.The invention thus relates to a product temperature treatment facility arranged in a pallet or the like said installation having the technical features of claim 1.

En se reportant particulièrement à la
Cette installation 1 comprend des moyens d'introduction d'une palette, ces moyens n'étant pas représentés dans les dessins annexés mais sont largement connus de l'homme du métier.This installation 1 comprises means for introducing a pallet, these means not being shown in the accompanying drawings but are widely known to those skilled in the art.
L'installation 1 comporte en outre des moyens de convoyage 5 de la palette entre une entrée et une sortie de l'installation 1 ainsi que des moyens de soufflage d'air 6 à travers les produits 2 de la palette 3.The installation 1 further comprises conveying means 5 of the pallet between an inlet and an outlet of the installation 1 as well as air blowing means 6 through the
Selon l'invention, l'installation 1 comprend en outre des moyens de séparation longitudinale 7 relevable.According to the invention, the installation 1 further comprises longitudinal separation means 7 liftable.
Ces moyens de séparation 7 sont disposés sensiblement dans l'axe principal de ladite au moins une chambre et permettent d'empêcher l'écoulement d'air entre la surface supérieure 8 de chaque palette 3 et le plafond 9 de ladite au moins une chambre 4.These separation means 7 are arranged substantially in the main axis of said at least one chamber and make it possible to prevent the flow of air between the
De manière avantageuse, ces moyens de séparation longitudinale 7 occuperont la totalité de la longueur de la chambre 4 et on prévoira des moyens de séparation longitudinale 7 au niveau de chaque chambre 4.Advantageously, these longitudinal separation means 7 will occupy the entire length of the chamber 4 and longitudinal separation means 7 will be provided at each chamber 4.
Bien entendu, selon d'autres modes de réalisation, il est également possible de prévoir que certaines chambres 4 ne soient pas équipées de ces moyens de séparation longitudinale 7 et par exemple, la dernière chambre dite chambre de sortie.Of course, according to other embodiments, it is also possible to provide that certain rooms 4 are not equipped with these longitudinal separation means 7 and for example, the last chamber called exit chamber.
En se reportant cette fois plus particulièrement aux
Plus précisément, les moyens de déplacement 10 permettent le relèvement ou la mise en place de ces éléments souples 11.More specifically, the displacement means 10 allow the recovery or the placement of these
Selon le mode de réalisation décrit aux
Cela étant, il est également possible d'envisager la réalisation de moyens de séparation 7 longitudinale avec une seule rangée d'éléments souples 11.However, it is also possible to envisage the realization of longitudinal separation means 7 with a single row of
Selon un mode de réalisation préféré de l'invention, les moyens de déplacement 10 comprennent deux tubes intérieur 12 et extérieur 13, le tube extérieur 13 portant les éléments souples 11 et le tube intérieur 12 portant un taquet 14 dont le relèvement entraîne la rotation du tube extérieur 13 et le relèvement des éléments souples 11.According to a preferred embodiment of the invention, the displacement means 10 comprise two
On voit à la
Le passage de la position basse à la position haute est obtenu en venant effectuer une rotation au niveau du tube 12, le taquet 14 entraînant le relèvement des éléments souples 11 en venant appuyer sur ces derniers.The passage from the low position to the high position is obtained by coming to rotate at the
Les éléments souples 11 peuvent être notamment constitués de poils tels que représentés notamment à la
Toutefois, il s'agit d'un exemple non limitatif et on pourra également réaliser ces éléments souples à partir de lattes.However, this is a non-limiting example and we can also achieve these flexible elements from slats.
Dans l'exemple des
Compte tenu de la structure de ces éléments souples 11 qu'ils soient constitués de lattes ou de poils, le contact avec la surface supérieure 8 est léger permettant de ne pas endommager les produits pouvant constituer eux-mêmes la surface supérieure 8 de la palette.Given the structure of these
Selon un mode de réalisation avantageux de l'invention, on peut également prévoir que ces éléments souples 11 soient reliés entre eux dans leur partie haute formant un rideau entièrement étanche à l'air.According to an advantageous embodiment of the invention, it is also possible that these
Cette partie haute a un positionnement tel que son extrémité inférieure est toujours au dessus de la surface supérieure 8 de la palette 3 la plus haute prévue dans la chambre 4.This upper part has a positioning such that its lower end is always above the
Il est à noter également que ces moyens de séparation 7 longitudinale comprennent également des moyens de commande 15 permettant l'entraînement des moyens de déplacement 10, ces moyens de commande 15 étant notamment réalisés par un vérin.It should also be noted that these longitudinal separation means 7 also comprise control means 15 for driving the displacement means 10, these control means 15 being in particular made by a jack.
Bien entendu, d'autres possibilités de motorisation et de commande des moyens de déplacement 10 connues de l'homme de métier pourront également être utilisées.Of course, other possibilities of motorization and control of the displacement means 10 known to those skilled in the art may also be used.
Il est également important de signaler que le fonctionnement des moyens de déplacement 10 est concomitant avec le fonctionnement des moyens de convoyage 5.It is also important to note that the operation of the displacement means 10 is concomitant with the operation of the conveying
En effet, avant tout déplacement des palettes 3 par les moyens de convoyage 5, on réalise de préférence de manière automatique la levée par les moyens de déplacement 10 des éléments souples 11.Indeed, before any movement of the
Lorsque les moyens de convoyage 5 de la palette sont stoppés, les moyens de déplacement 10 sont actionnés et positionnent le taquet 14 en position basse permettant la mise en place des éléments souples 11 contre la surface supérieure 8 des palettes 3.When the conveying

Dans ce mode de réalisation, les moyens de séparation longitudinale 7 comprennent un arbre d'entraînement 20 équipé de moyens de retenue 21 et permettant l'entraînement de bras articulés 22 dans le sens de la montée tel qu'illustré à la
Les moyens de séparation longitudinale 7 comportent également au moins une bâche d'étanchéité 23 liée aux bras articulés 22.The longitudinal separation means 7 also comprise at least one sealing
En se reportant cette fois plus particulièrement à la
On voit ainsi, à la
En se reportant cette fois principalement à la
Cette caractéristique est particulièrement intéressante puisqu'elle permet, lorsque l'axe d'entraînement 20 abaisse les bras 22 en direction des produits que l'effort exercé par la bâche 23 sur les produits soit réparti sur la face inférieure de l'extrémité distale 26 du bras articulé 22.This feature is particularly interesting since it allows, when the
Le relèvement des parties de rangs inférieurs par rapport aux parties de rangs supérieurs permet donc de répartir sur une large surface l'effort exercé par la bâche sur les produits et d'éviter par là même toute détérioration du produit palettisé.The raising of the parts of lower ranks with respect to the higher rank parts therefore makes it possible to distribute over a large surface the force exerted by the tarpaulin on the products and thus to prevent any deterioration of the palletised product.
L'utilisation de bras articulés qui sont tous indépendants les uns des autres permet également de récupérer les écarts de niveau sur les palettes ; en effet, lors de la descente des bras articulés 22, les taquets 24 maintiennent les bras 22 jusqu'à leur arrêt sur la palette puis continuent la rotation en laissant le bras 22 à sa place en fin de descente, à la fin de la rotation de l'arbre 20, l'ensemble des bras 22 ont leur extrémité distale 26 en contact avec le produit palettisé.The use of articulated arms which are all independent of each other also makes it possible to recover the level deviations on the pallets; in fact, during the descent of the articulated
En fonction des caractéristiques du tunnel, on pourra utiliser différents types de bras articulés 22 et notamment, comme représenté aux
Le dimensionnement ou également l'espacement entre les bras articulés 22 pourra être variable et notamment, les bras articulés pourront être espacés de 20 à 100 cm sur ledit arbre d'entraînement 20.The dimensioning or also the spacing between the articulated
A ce niveau, il est important de noter que l'arbre d'entraînement 20 sera avantageusement mis en rotation par des moyens de commande 27 comportant un vérin.At this level, it is important to note that the
Bien entendu, d'autres modes de réalisation des moyens de commande 27, à la portée de l'homme du métier, pourront également être envisagés.Of course, other embodiments of the control means 27, within the reach of those skilled in the art, may also be considered.
Selon une caractéristique de l'invention, les bras 22 sont liés à la bâche 23 qui, avantageusement, comprend des poches 30 permettant l'introduction des bras articulés 22.According to one characteristic of the invention, the
Selon un mode de réalisation avantageux, la liaison entre les bras 22 et la bâche d'étanchéité 23 est amovible.According to an advantageous embodiment, the connection between the
Toutefois, on pourra envisager dans d'autres modes de réalisation que l'assujettissement dans les poches 30 soit fixe ou encore que les bras 22 ne soient pas fixés dans des poches 30 mais sur une face de la bâche d'étanchéité 23.However, it can be envisaged in other embodiments that the securing in the
De manière à permettre le débattement angulaire entre les bras 22, on prévoit au niveau de la bâche d'étanchéité des soufflets 28 ménagés entre les poches 30.In order to allow the angular displacement between the
Avantageusement, ces soufflets 28 auront une forme évasée en direction de l'extrémité basse 29 de la bâche 23.Advantageously, these
Cette caractéristique permet d'autoriser le placement de deux bras articulés 22 voisins à des hauteurs différentes et notamment, avec des écarts de hauteur compris 20 cm et 1 m permettant par conséquent de pouvoir étanchéifier la partie haute de l'installation même lorsque les palettes présentent des écarts de hauteur importants.This feature makes it possible to allow the placement of two adjacent articulated
Selon l'invention, on prévoit également des moyens de séparation additionnels 16, disposés sensiblement perpendiculairement et aux extrémités des moyens de séparation longitudinale 7 et permettant d'empêcher l'écoulement d'air entre deux chambres 4 au niveau des parties hautes.According to the invention, there is also provided additional separation means 16 disposed substantially perpendicularly and at the ends of the longitudinal separation means 7 and for preventing the flow of air between two chambers 4 at the upper parts.
Ces moyens de séparation additionnels 16 comportent des moyens de déplacement additionnels 17 et une guillotine 18, les moyens de déplacement additionnels 17 permettant un déplacement en translation de la guillotine 18 entre une position de travail abaissée et une position relevée.These additional separation means 16 comprise additional displacement means 17 and a
On voit aux
Selon un mode de réalisation préféré, les moyens de déplacement additionnels 17 sont synchronisés avec les moyens de déplacement 10 des éléments souples 11.According to a preferred embodiment, the additional displacement means 17 are synchronized with the displacement means 10 of the
On pourra notamment prévoir que les moyens de déplacement 10 et 17 soient actionnés par les moyens de commande 15, 27.It will be possible in particular to provide that the displacement means 10 and 17 are actuated by the control means 15, 27.
L'association entre les moyens de séparation longitudinale 7 et les moyens de séparation additionnels 16 permet d'assurer une bonne étanchéité de l'ensemble des parties hautes, c'est-à-dire des parties situées au dessus de la surface supérieure 8 des palettes 3.The association between the longitudinal separation means 7 and the additional separation means 16 ensures a good seal of all the upper parts, that is to say parts located above the
L'installation de traitement ainsi équipée est par conséquent particulièrement performante puisque l'air sortant des moyens de soufflage 6 est nécessairement forcé à travers la palette 3.The treatment plant thus equipped is therefore particularly efficient since the air leaving the blowing means 6 is necessarily forced through the
Selon une option avantageuse de l'invention, on peut également prévoir des moyens d'étanchéité latéraux 19.According to an advantageous option of the invention, it is also possible to provide lateral sealing means 19.
Pour ce faire, on prévoit que les palettes 3 soient introduites dans l'installation 1 de manière à être alignées sur un côté présentant en quelle que sorte une surface de référence.To do this, it is expected that the
Compte tenu des différences soit d'orientation des palettes, soit des dimensions de ces palettes 3, le côté opposé au côté aligné présente des décalages et par conséquent un espace par lequel l'air peut s'échapper.Given the differences in orientation of the pallets or the dimensions of these
Selon le mode de réalisation avantageux, les moyens d'étanchéité 19 latéraux permettent de venir combler cet espace et notamment avantageusement au niveau des extrémités des chambres 4.According to the advantageous embodiment, the lateral sealing means 19 make it possible to fill this space and in particular advantageously at the ends of the chambers 4.
Ces moyens d'étanchéité 19 pourront comporter des portes coulissantes 20 disposées sensiblement perpendiculairement à l'axe principal de chaque chambre 4.These sealing means 19 may comprise sliding
Là encore, ces moyens d'étanchéité latéraux 19 seront synchronisés avec les moyens de convoyage 5, la porte étant déplacée vers l'intérieur de la chambre 4 lorsque les moyens de convoyage 5 sont stoppés et inversement, la porte viendra coulisser dans les parois de l'installation 1 avant tout déplacement des moyens de convoyage 5.Again, these lateral sealing means 19 will be synchronized with the conveying
Ces moyens d'étanchéité latéraux 19 permettent également d'augmenter le rendement énergétique de l'installation de traitement 1.These lateral sealing means 19 also make it possible to increase the energy efficiency of the treatment plant 1.
Ils permettent également pour un opérateur d'accéder aisément à l'intérieur de l'installation en cas de problème, notamment en cours de fonctionnement de l'installation. A cet effet, on peut prévoir une commande extérieure à l'installation autorisant l'ouverture et/ou la fermeture de l'ensemble des portes 20 de l'installation 1.They also allow an operator to easily access the interior of the installation in case of problems, especially during operation of the installation. For this purpose, it is possible to provide an external control to the installation allowing the opening and / or closing of all the
Bien entendu, d'autres modes de réalisation à la portée de l'homme de l'art auraient également pu être envisagés sans pour autant sortir du cadre de l'invention définie par les revendications ci-après.Of course, other embodiments within the reach of those skilled in the art could also be envisaged without departing from the scope of the invention defined by the claims below.
