Description

La présente invention concerne le domaine des systèmes d'obturation ou de fermeture de passages du type ouverture d'accès ou orifice d'alimentation et d'évacuation, sous la forme d'un vantail mobile en translation ou en pivotement.The present invention relates to the field of systems closing or closing passages of the access opening type or supply and exhaust port, in the form of a movable leaf in translation or pivoting.

Elle a pour objet un dispositif de porte, notamment pour cuve, cuve de macération, pressoir, et en particulier pour pressoir pneumatique, un pressoir équipé d'un tel dispositif de porte et un procédé de fabrication d'une porte d'un tel dispositif.It relates to a door device, in particular for a tank, maceration tank, press, and in particular for pneumatic press, a press equipped with such a door device and a manufacturing process of a door of such a device.

De nombreux contenants de grande taille et comportant une ouverture d'accès sont munis de dispositifs de fermeture du type porte, qui sont de structure complexe, fastidieux à fabriquer car assemblés à partir de pièces nombreuses et surtout présentent une masse totale importante nécessitant l'application de forces de poussée et de traction adaptées en intensité.Many large containers with a access opening are fitted with door-type closing devices, which are of complex structure, tedious to manufacture because assembled from numerous parts and above all have a large total mass requiring the application of suitable thrust and traction forces in intensity.

Ainsi, les portes de pressoirs, notamment de pressoirs pneumatiques à membranes, destinées à fermer l'ouverture de chargement de raisins ou de fruits et de déchargement des résidus de pressurage (marc pour le raisin), sont actuellement de constitution complexe car incorporant notamment un joint gonflable, sont réalisées par assemblage de plusieurs pièces, généralement par l'intermédiaire d'ensembles vis/ écrous, et présentent un poids important car formées de pièces structurelles pleines, en particulier pour aboutir à une porte à rigidité mécanique suffisante pour résister aux pressions s'appliquant sur elle au moment des phases de pressurage.Thus, the doors of presses, in particular presses diaphragm tires, intended to close the loading opening grapes or fruit and unloading of pressing residues (marc for grapes), are currently complex because they incorporate including an inflatable seal, are made by assembling several parts, usually via screw / nut assemblies, and present a significant weight because formed of solid structural parts, in particular to lead to a door with sufficient mechanical rigidity to resist the pressures applied to it during the phases of pressing.

Le déplacement de ces portes de pressoir s'effectue actuellement, pour des raisons de commodité et de niveau d'intensité de force de poussée à fournir, par des actionneurs pneumatiques, alimentés par la source d'air sous pression alimentant également la membrane du pressoir.These press doors are moved currently, for reasons of convenience and level of intensity of thrust force to be supplied, by pneumatic actuators, powered by the source of pressurized air also supplying the press membrane.

Toutefois, de tels actionneurs pneumatiques ne permettent pas un réglage fin du positionnement de la porte à l'état ouvert, comme cela est nécessaire en cas de vidange d'une cuve alimentée avec des fruits et des raisins de type et de maturité variables et/ ou ayant subi des degrés de pressurage différents (compactage et imbrication plus ou moins importants des grappes pressées par exemple), pour éviter un engorgement ou un bourrage.However, such pneumatic actuators do not allow fine adjustment of the positioning of the door in the open state, as is necessary when emptying a tank supplied with fruit and grapes of variable type and maturity and / or having undergone degrees of different pressing (more or less important compaction and nesting) pressed clusters for example), to avoid waterlogging or jam.

Une solution possible pour contrôler de manière précise le positionnement de la porte pourrait consister à mettre en oeuvre des moyens d'actionnement électriques.A possible solution to precisely control the positioning of the door could consist of implementing means electric actuators.

Néanmoins, avec les portes actuelles il faudrait disposer d'actionneurs de grande puissance, trop encombrants pour être montés à proximité de l'ouverture dont les alentours doivent demeurer dégagés et surtout qui nécessiteraient un système d'alimentation spécifique additionnel, par exemple en triphasé, permettant d'acheminer la puissance nécessaire. Il en résulterait un surcoût important et une augmentation des risques liés au fonctionnement d'un tel pressoir.However, with the current doors it would be necessary to have high power actuators, too bulky to be mounted on near the opening, the surroundings of which must remain clear and especially that would require an additional specific feeding system, for example in three-phase, allowing to convey the necessary power. he this would result in a significant additional cost and an increase in risks linked to operation of such a press.

Par ailleurs, il existe, de manière générale, indépendamment du domaine d'application précité, une demande constante pour des portes allégées, aisées à fabriquer et d'un prix de revient faible.In addition, there is, generally speaking, independently of the aforementioned field of application, constant demand for doors light, easy to manufacture and low cost.

La présente invention a notamment pour but de pallier les inconvénients précités.The present invention aims in particular to overcome the aforementioned drawbacks.

A cet effet, l'invention a pour objet un dispositif de porte, notamment pour cuve, cuve de macération, pressoir, et en particulier pour pressoir pneumatique à membrane, pourvu(e) d'au moins une ouverture de chargement et de déchargement, la porte présentant une forme d'ensemble cintrée épousant sensiblement la courbure de la paroi de la cuve, caractérisé en ce que ladite porte est principalement constituée par une enveloppe structurelle sous la forme d'une plaque métallique pourvue de bords latéraux pliés et par un corps de remplissage, également en forme de plaque, montée dans l'enveloppe, ledit corps étant maintenu dans ladite enveloppe par les bords pliés de cette dernière, sous l'effet du cintrage subi par l'ensemble enveloppe / corps et de la disposition imbriquée cintrée résultante.To this end, the invention relates to a door device, especially for vats, maceration vats, presses, and in particular for pneumatic diaphragm press, provided with at least one opening loading and unloading, the door having an overall shape curved substantially following the curvature of the wall of the tank, characterized in that said door is mainly constituted by an envelope structural in the form of a metal plate provided with edges folded sides and by a filling body, also in the form of plate, mounted in the envelope, said body being held in said envelope by the folded edges of the latter, under the effect of the bending undergone by the envelope / body assembly and the curved nested arrangement resultant.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue partielle en perspective d'une cuve de pressoir équipé d'un dispositif de porte selon un premier mode de réalisation de l'invention, à l'état ouvert ;
  • la figure 2 est une vue en perspective du dispositif de porte de la figure 1, vue selon une autre direction, et à une échelle différente ;
  • la figure 3 est une vue de dessus de l'ensemble de porte de la figure 2, à l'état fermé et à une échelle différente ;
  • la figure 4 est une vue en coupe selon A-A de la porte du dispositif de porte de la figure 3, selon une variante de réalisation de l'invention,
  • les figures 5 et 6 sont des vues en perspective d'un dispositif de porte selon un second mode de réalisation de l'invention, respectivement à l'état ouvert et à l'état fermé.
    • The invention will be better understood from the following description, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a partial perspective view of a press tank equipped with a door device according to a first embodiment of the invention, in the open state;
  • Figure 2 is a perspective view of the door device of Figure 1, seen in another direction, and on a different scale;
  • Figure 3 is a top view of the door assembly of Figure 2, in the closed state and on a different scale;
  • FIG. 4 is a sectional view along AA of the door of the door device of FIG. 3, according to an alternative embodiment of the invention,
  • Figures 5 and 6 are perspective views of a door device according to a second embodiment of the invention, respectively in the open state and in the closed state.

    • Les figures 1 à 6 des dessins annexés montrent un dispositif de porte 1, en particulier pour pressoir pneumatique à membrane, dont la cuve 2 est pourvue d'au moins une ouverture de chargement et de déchargement, la porte 4 présentant une forme d'ensemble cintrée épousant sensiblement la courbure de la paroi de la cuve 2 cylindrique ou au moins partiellement cylindrique.Figures 1 to 6 of the accompanying drawings show a device for door 1, in particular for a pneumatic membrane press, including the tank 2 is provided with at least one loading and unloading opening, door 4 having a curved overall shape substantially matching the curvature of the wall of the tank 2 cylindrical or at least partially cylindrical.

    Conformément à l'invention, ce dispositif 1 est caractérisé en ce que ladite porte 4 est principalement constituée par une enveloppe structurelle 5 sous la forme d'une plaque métallique pourvue de bords latéraux pliés 5' et par un corps de remplissage 6, également en forme de plaque, montée dans l'enveloppe 5, ledit corps 6 étant maintenu dans ladite enveloppe 5 par les bords pliés 5' de cette dernière, sous l'effet du cintrage subi par l'ensemble enveloppe 5/ corps 6 et de la disposition imbriquée cintrée résultante.According to the invention, this device 1 is characterized in that that said door 4 is mainly constituted by an envelope structural 5 in the form of a metal plate provided with edges folded sides 5 'and by a filling body 6, also in the form of plate, mounted in the envelope 5, said body 6 being held in said envelope 5 by the folded edges 5 ′ of the latter, under the effect of the bending undergone by the envelope 5 / body 6 assembly and the nested arrangement resulting arch.

    Tirant profit de l'allègement de la structure de la porte 4 résultant des dispositions précitées, il peut être avantageusement prévu que ladite porte 4 sera déplaçable de manière contrôlée entre une position d'obturation totale et une position de libération totale de l'ouverture de chargement et de déchargement 3 par un actionneur électrique commandé par l'opérateur et/ ou par l'unité de pilotage du pressoir.Taking advantage of the lightening of the door structure 4 resulting from the aforementioned provisions, it can be advantageously provided that said door 4 can be moved in a controlled manner between a position total shutter and a position of total release of the opening of loading and unloading 3 by a controlled electric actuator by the operator and / or by the press control unit.

    En effet, la structure extrêmement simple du corps de la porte 4, notamment dépourvue de toute pièce d'assemblage, permet d'aboutir à un poids total limité. De ce fait, ladite porte 4 peut être déplacée par un actionneur électrique 7 de petite taille et de puissance limitée, alimenté en dérivation par le réseau alimentant déjà le pressoir, en particulier l'unité de commande (non représenté du pressoir considéré). Indeed, the extremely simple structure of the door body 4, in particular devoid of any assembly part, makes it possible to achieve a total weight limited. Therefore, said door 4 can be moved by a electric actuator 7 of small size and limited power, supplied with bypass by the network already supplying the press, in particular the control (not shown of the press in question).

    Les bords pliés 5' pourront, éventuellement, être prolongés par des portions d'extrémité repliées 5" (voir figure 4) maintenant le corps de remplissage 6 contre la partie centrale étendue de l'enveloppe 5.The folded edges 5 ′ may possibly be extended by 5 "folded end portions (see Figure 4) holding the body filling 6 against the extended central part of the casing 5.

    Comme cela ressort des figures des dessins annexés, le déplacement de la porte 4 s'effectue dans une direction parallèle à la génératrice de la paroi de la cuve 2 cylindrique ou à l'axe longitudinal de cette dernière.As can be seen from the figures in the accompanying drawings, the door 4 is moved in a direction parallel to the generator of the wall of the tank 2 cylindrical or at the longitudinal axis of the latter.

    Afin d'alléger davantage encore la porte 4 et d'en réduire au maximum le coût de revient, tout en fournissant une structure solide et une bonne étanchéité, la plaque 6 formant corps de remplissage peut, par exemple, consister en une plaque pleine en un matériau polymérique et/ ou plastique, rigide mais déformable, et comporte un joint gonflable 8 en forme de boucle ou d'anneau, monté dans une rainure 6' de réception ménagée dans ladite plaque 6 et destiné à venir en application étanche autour de l'ouverture de chargement et de déchargement 3, à l'état gonflé et en position d'obturation de ladite porte 4 (figure 4).In order to further lighten door 4 and reduce it to maximum cost price, while providing a solid structure and good sealing, the plate 6 forming a filling body can, by example, consist of a full plate of polymeric material and / or plastic, rigid but deformable, and has an inflatable seal 8 in loop or ring shape, mounted in a 6 'receiving groove formed in said plate 6 and intended to come in sealed application around the loading and unloading opening 3, in the inflated state and in the closed position of said door 4 (Figure 4).

    Le corps 6 pourra toutefois également être réalisé en un autre matériau, notamment métallique (par exemple de l'aluminium), pouvant subir sans dommage un cintrage au moins limité.The body 6 may however also be produced in another material, in particular metallic (for example aluminum), which can undergo at least limited bending without damage.

    De plus, le corps 6 pourra également, en variante, présenter une structure creuse, par exemple renforcée par des nervures ou des parois internes.In addition, the body 6 may also, as a variant, have a hollow structure, for example reinforced by ribs or walls internal.

    De manière générale, ledit corps 6 devra répondre aux critères suivants : être relativement léger, pouvoir recevoir et maintenir le joint gonflable, pouvoir subir un cintrage et être suffisamment résistant pour transmettre sans déformation notable les pressions appliquées sur sa face interne à l'enveloppe 5.In general, said body 6 must meet the criteria following: be relatively light, able to receive and maintain the joint inflatable, able to undergo bending and be strong enough to transmit without significant deformation the pressures applied on its face internal to the envelope 5.

    L'enveloppe structurelle 5 est, quant à elle, avantageusement réalisée en tôle (préférentiellement traitée anti-corrosion) et présente une section transversale sensiblement en U, dont les bords pliés 5' forment les ailes.The structural envelope 5 is, for its part, advantageously made of sheet metal (preferably anti-corrosion treated) and has a substantially U-shaped cross section, the folded edges 5 'of which form the wings.

    Pour renforcer la rigidité de la porte 4, notamment lorsque celle-ci est de grande dimension et soumise à de fortes pressions, l'enveloppe 5 peut être munie sur sa face externe, opposée au corps de remplissage, de renforts creux 9 allongés, formés dans ou rapportés sur cette face de ladite enveloppe 5. To strengthen the rigidity of door 4, especially when it is large and subject to strong pressures, the casing 5 can be provided on its external face, opposite the body of filling, of elongated hollow reinforcements 9, formed in or attached to this face of said envelope 5.

    Selon une variante de réalisation avantageuse de l'invention, représentée aux figures des dessins annexés, les renforts creux 9 consistent en des profilés en U, rapportés sur la face externe de l'enveloppe 5 en étant fixés sur cette dernière, par exemple par soudage, de manière continue au niveau de bords libres 9" droits de leurs ailes 9' ou de manière discontinue au niveau des segments proéminents de bords libres 9" crénelés de leurs ailes 9', lesdits profilés 9 s'étendant parallèlement entre eux et transversalement sur toute la largeur de la porte 4 dans une direction parallèle à celle de la génératrice de ladite enveloppe 5.According to an advantageous alternative embodiment of the invention, shown in the figures of the accompanying drawings, the hollow reinforcements 9 consist in U-shaped sections, attached to the external face of the casing 5 while being fixed to the latter, for example by welding, continuously at level of free edges 9 "straight from their wings 9 'or discontinuously at the level of the prominent segments of free edges 9 "crenellated with their wings 9 ', said sections 9 extending parallel to each other and transversely across the width of door 4 in one direction parallel to that of the generator of said envelope 5.

    Une fixation discontinue par segments des profilés en U 9 (par exemple par soudage), permet à la structure d'ensemble de la porte 4 de conserver une faible capacité de déformation, de fournir des ouvertures en forme de fentes autorisant le nettoyage des volumes délimités par lesdits profilés 9, ainsi que de faciliter leur solidarisation (figures 1 à 3).A discontinuous fixing by segments of the U-shaped profiles 9 (by example by welding), allows the overall structure of door 4 to maintain a low deformation capacity, provide openings in form of slots authorizing the cleaning of the volumes delimited by said profiles 9, as well as to facilitate their joining (Figures 1 to 3).

    Une fixation continue des profilés en U 9 permet de renforcer davantage la structure de la porte 4 et de répartir les contraintes sur une section plus importante (figures 5 et 6).Continuous fixing of the U-shaped profiles 9 makes it possible to reinforce further the structure of door 4 and to distribute the stresses over a larger section (Figures 5 and 6).

    En vue de rigidifier davantage la porte 4 dans une direction perpendiculaire à celle des renforts creux 9 et de permettre un montage résistant de cette dernière sur la cuve 2, la porte 4 peut être également pourvue d'au moins deux éléments de renfort 10, par exemple sous la forme de barres plates ou de bandes métalliques rigides allongées, présentant éventuellement une incurvation correspondant sensiblement à celle de la porte 4, s'étendant dans des plans espacés respectifs perpendiculaires à la génératrice de l'enveloppe structurelle 5 de ladite porte 4, en étant préférentiellement rapportés le long des deux bords opposés perpendiculaires aux bords latéraux pliés 5' de ladite enveloppe 5.In order to further stiffen door 4 in one direction perpendicular to that of the hollow reinforcements 9 and to allow mounting resistant of the latter on the tank 2, the door 4 can also be provided with at least two reinforcing elements 10, for example in the form flat bars or elongated rigid metal strips having possibly a curvature corresponding substantially to that of the door 4, extending in respective spaced planes perpendicular to the generator of the structural envelope 5 of said door 4, being preferably reported along the two opposite edges perpendicular to the folded side edges 5 'of said envelope 5.

    Bien qu'un montage pivotant de la porte 4 soit possible, il est toutefois préféré, en particulier en relation avec une application sur un pressoir, que ladite porte 4 consiste en une porte coulissante, dont l'actionnement motorisé est plus aisé.Although pivoting mounting of door 4 is possible, it is preferred however, in particular in connection with an application on a press, that said door 4 consists of a sliding door, of which motorized actuation is easier.

    En particulier, l'actionneur électrique 7 consiste avantageusement en un vérin électrique dont l'extrémité frontale de sa tige mobile 7' est solidaire de l'enveloppe structurelle 5. Ledit vérin 7 est ainsi situé en dehors de la région environnante proche de l'ouverture 3 et le déplacement de ladite porte 4 n'engendre aucun battement, ni aucun mouvement d'ampleur spatiale similaire. In particular, the electric actuator 7 consists advantageously in an electric actuator whose front end of its rod mobile 7 ′ is integral with the structural envelope 5. Said jack 7 is thus located outside the surrounding area near opening 3 and the movement of said door 4 does not generate any flapping, nor movement of similar spatial magnitude.

    Selon un mode de réalisation préféré de l'invention, représenté avec figures 1 à 3 des dessins annexés, la porte 4 comporte au niveau de l'un de ses bords latéraux pliés 5' au moins deux bagues ou oeillets 11 coulissant sur une tige ou barre de guidage 12 solidaire de la cuve 2 et au niveau de son bord latéral plié 5' opposé une tige ou barre 13 coulissant dans au moins une bague ou au moins un oeillet de guidage 14 solidaire de la cuve 2.According to a preferred embodiment of the invention, shown with Figures 1 to 3 of the accompanying drawings, the door 4 has at one of its folded side edges 5 'at least two rings or eyelets 11 sliding on a rod or guide bar 12 integral with the tank 2 and at level of its folded lateral edge 5 'opposite a sliding rod or bar 13 in at least one ring or at least one guide eyelet 14 integral with tank 2.

    L'absence de tige de guidage longitudinal fixe d'un côté de l'ouverture 3 permet de dégager complètement ce côté en position ouverte de la porte 4, en éliminant ainsi tout obstacle proéminent susceptible de retenir des matières déversées de cette ouverture 3.The absence of a fixed longitudinal guide rod on one side of opening 3 allows this side to be completely released in the open position of door 4, thereby eliminating any prominent obstacle likely to retain material spilled from this opening 3.

    Avantageusement, les bagues ou oeillets 11, d'une part, et la tige ou barre 13, d'autre part, sont montés sur les deux éléments de renfort 10 s'étendant le long des bords non pliés de l'enveloppe 5, au niveau d'extrémités opposées de ces derniers.Advantageously, the rings or eyelets 11, on the one hand, and the rod or bar 13, on the other hand, are mounted on the two reinforcing elements 10 extending along the unfolded edges of the envelope 5, at the level opposite ends of these.

    Afin d'éviter tout grippage pouvant aboutir à un blocage de la porte 4 en cours de déplacement, tout en garantissant une solidarisation très résistante de la porte 4 avec la cuve 2 dans sa position de fermeture, la tige ou barre 13 coulisse dans une unique bague de guidage 14, ladite tige ou barre 13 comportant une portion saillante 13' prolongeant son extrémité frontale et destinée à venir s'engager dans une bague ou un oeillet d'ancrage 15 supplémentaire solidaire de la cuve 2, ce en position d'obturation de la porte 4 coulissante.In order to avoid any seizure which could lead to blockage of the door 4 during movement, while ensuring a very solidarisation resistant door 4 with tank 2 in its closed position, the rod or bar 13 slides in a single guide ring 14, said rod or bar 13 having a projecting portion 13 'extending its end frontal and intended to come to engage in a ring or an anchoring eyelet 15 additional integral with the tank 2, this in the closed position of the sliding door 4.

    Conformément à une variante de réalisation avantageuse de l'invention, la tige ou barre de guidage 12, la bague ou l'oeillet de guidage 14 et la bague ou l'oeillet d'ancrage 15 sont fixé(e)s sur une plaque support cintrée 16 rapportée intimement contre la face externe de la paroi de la cuve 2 au niveau de la zone entourant l'ouverture de chargement et de déchargement 3, ladite plaque support 16 comportant elle-même une découpe 16' coïncidant sensiblement avec ladite ouverture 3.In accordance with an advantageous variant of the invention, the guide rod or bar 12, the guide ring or the eyelet 14 and the anchor ring or eyelet 15 are fixed on a support plate curved 16 intimately attached against the external face of the wall of the tank 2 at the level of the area around the loading and unloading 3, said support plate 16 itself comprising a cutout 16 'substantially coinciding with said opening 3.

    Une telle constitution permet de réaliser le dispositif de porte 1 sous la forme d'un sous-ensemble préassemblé, de lui assurer une bonne rigidité structurelle et de faciliter sa solidarisation avec la cuve 2.Such a constitution makes it possible to produce the door device 1 in the form of a pre-assembled sub-assembly, to ensure good structural rigidity and to facilitate its joining with the tank 2.

    Chaque bague ou oeillet 11, 14 et 15 pourra consister en une douille en une matière à faible coefficient de friction montée dans un orifice correspondant. Each ring or eyelet 11, 14 and 15 may consist of a bush made of low friction material mounted in an orifice corresponding.

    Comme le montrent les figures 5 et 6 des dessins annexés, la plaque support 16 peut être munie d'éléments de renfort et de fixation 17, 17' reliant ladite plaque 16 à la paroi de cuve 2, le cas échéant sous la forme de barres plates ou de bandes métalliques rigides allongées, montées sur chants, présentant éventuellement une incurvation épousant sensiblement celle de la paroi de la cuve 2 et s'étendant dans des plans espacés respectifs perpendiculaires à la génératrice de l'enveloppe de ladite paroi.As shown in Figures 5 and 6 of the accompanying drawings, the support plate 16 can be provided with reinforcing and fixing elements 17, 17 'connecting said plate 16 to the tank wall 2, if necessary in the form flat bars or elongated rigid metal strips, mounted on edges, possibly having a curvature substantially matching that of the wall of the tank 2 and extending in respective spaced planes perpendicular to the generatrix of the envelope of said wall.

    La présente invention concerne également un pressoir pneumatique à membrane, dont la cuve 2 est pourvue d'au moins une ouverture 2 de chargement et de déchargement, caractérisé en ce qu'il est muni, pour l'obturation et la libération contrôlées d'au moins une ouverture de chargement et de déchargement 3, d'un dispositif de porte 1 tel que décrit précédemment.The present invention also relates to a press pneumatic diaphragm, of which tank 2 is provided with at least one loading and unloading opening 2, characterized in that it is provided for at least one opening for controlled closure and release loading and unloading 3, of a door device 1 as described previously.

    Enfin, l'invention concerne aussi un procédé de fabrication d'une porte, notamment d'une porte pour un dispositif de porte 1 du type décrit ci-dessus.Finally, the invention also relates to a manufacturing process a door, in particular a door for a door device 1 of the type described above.
