Description

ARRANGEMENT DE PORTE PERMETTANT UN TRANSFERT ETANCHE ENTRE DEUX VOLUMES CLOSDOOR ARRANGEMENT ALLOWING A SEALED TRANSFER BETWEEN TWO CLOSED VOLUMES
DOMAINE TECHNIQUE DE L’INVENTION TECHNICAL FIELD OF THE INVENTION
[001] La présente invention concerne un arrangement de porte destiné à équiper un premier volume clos et apte à permettre un raccordement étanche d’un deuxième volume clos sur le premier volume clos. The present invention relates to a door arrangement intended to equip a first closed volume and able to allow a sealed connection of a second closed volume on the first closed volume.
[002] Par volume, on entend dans la présente demande tout produit, équipement ou installation délimitant un volume. Ainsi, il peut s’agir d’une enceinte, d’un isolateur, d’un récipient, d’un conteneur, d’un sac, etc. By volume is meant in the present application any product, equipment or installation delimiting a volume. Thus, it can be an enclosure, isolator, vessel, container, bag, etc.
[003] Par volume clos, on entend un volume isolé du milieu extérieur. Il peut s’agir notamment, mais non exclusivement, d’un volume de préparation, de stockage et/ou de manipulation de produits ne devant pas être en contact avec l'extérieur ou avec un utilisateur. By closed volume is meant a volume isolated from the external environment. It may be in particular, but not exclusively, a volume of preparation, storage and / or handling of products that must not be in contact with the outside or with a user.
[004] L’arrangement de porte est destiné notamment, mais non exclusivement, à raccorder deux volumes clos en vue de transférer des produits de l’un à l’autre sans rupture du confinement. Il peut s’agir par exemple du transfert de produits dangereux comme certains produits biologiques, chimiques ou radioactifs, du transfert de composants tels que bouchons, flacons, pistons, seringues, etc., du transfert de dispositifs de contrôle environnementaux tels que des plaques de milieu de culture, des compteurs particulaires, etc., du transfert de systèmes de nettoyage, du transfert de liquides, de poudres, d’outils, du transfert de déchets vers l’extérieur de l’enceinte et/ou du transfert de tout élément nécessaire à la production ou à la maintenance de la ligne de production. [004] The door arrangement is intended in particular, but not exclusively, to connect two closed volumes in order to transfer products from one to the other without breaking the containment. This may be for example the transfer of hazardous products such as certain biological, chemical or radioactive products, the transfer of components such as caps, vials, plungers, syringes, etc., the transfer of environmental control devices such as pressure plates. culture medium, particulate counters, etc., the transfer of cleaning systems, the transfer of liquids, powders, tools, the transfer of waste to the outside of the enclosure and / or the transfer of any element necessary for production or maintenance of the production line.
ETAT DE LA TECHNIQUE STATE OF THE ART
[005] Le transfert de produits d’un volume clos à un autre sans que le confinement de ces volumes ne soit rompu est une problématique délicate à résoudre. Pour répondre à celle-ci, des dispositifs de jonction étanches à double porte ont été développés. Citons par exemple ceux décrits dans les demandes de brevet FR2777822 et FR3036054. [005] The transfer of products from one closed volume to another without the containment of these volumes being broken is a difficult problem to resolve. To respond to this, sealed double door junction devices have been developed. Let us cite, for example, those described in patent applications FR2777822 and FR3036054.
[006] Ces dispositifs de jonction double porte sont formés par un premier et un deuxième ensemble porte/bride, l’un des ensembles porte/bride étant celui d’une des volumes, l’autre ensemble porte/bride étant celui de l’autre volume. Classiquement, le volume clos à raccorder est un récipient de type conteneur ou poche transportable tandis que l’autre volume clos sur lequel est raccordé le récipient est généralement une enceinte de manipulation fixe. Le raccordement du récipient à l’enceinte de manipulation est effectué par raccordement des ensembles porte/bride entre eux. Ce raccordement est réalisé généralement par la mise en prise d’un système dit à baïonnettes - des oreilles mâles de la bride et de la porte du récipient venant s'engager respectivement dans des encoches de la bride et de la porte de enceinte de manipulation - suivi d'une rotation du récipient permettant le verrouillage de la bride du récipient sur la bride de l’enceinte de manipulation ainsi que le verrouillage de la porte du récipient sur la porte de l’enceinte, le dé verrouillage des portes raccordées l’une à l’autre étant réalisé par dé verrouillage des portes de leurs brides respectives. These double door junction devices are formed by a first and a second door / flange assembly, one of the door / flange assemblies being that of one of the volumes, the other door / flange assembly being that of the other volume. Conventionally, the closed volume to be connected is a receptacle of the container or transportable bag type, while the other closed volume to which the receptacle is connected is generally a fixed handling enclosure. The container is connected to the handling chamber by connecting the door / flange assemblies to one another. This connection is generally made by engaging a so-called bayonet system - male ears of the flange and of the receptacle door respectively engaging in notches of the flange and of the handling enclosure door - followed by a rotation of the container allowing the locking of the container flange on the flange of the handling chamber as well as the locking of the container door on the chamber door, the unlocking of the doors connected one the other being achieved by unlocking the doors of their respective flanges.
[007] De manière connue, les portes des enceintes de manipulation sont fixées à leur bride respective par l’intermédiaire d’une charnière dont l’axe, vertical et latéral, est située sur la face intérieure de la bride ou de la paroi de l’enceinte, les portes se déplaçant de leur position de fermeture à leur position d’ouverture par rotation autour de la charnière et inversement. A l’état ouvert, les portes s’étendent de manière saillante au sein de l’enceinte, en étant disposées de manière plus ou moins perpendiculaire au plan de l’ouverture de passage, ce qui a pour conséquence d’entraver le passage des produits entre les volumes clos. Par ailleurs, le mouvement des portes au sein d’une enceinte a également pour inconvénient de générer des turbulences sous le flux laminaire, lesquelles turbulences brisent la barrière de protection immatérielle du process créé par le flux laminaire et par conséquent génère un risque de contamination du process. In known manner, the doors of the handling enclosures are fixed to their respective flange by means of a hinge whose axis, vertical and lateral, is located on the inner face of the flange or of the wall of the enclosure, the doors moving from their closed position to their open position by rotation around the hinge and vice versa. In the open state, the doors extend projectingly within the enclosure, being arranged more or less perpendicular to the plane of the passage opening, which has the consequence of hindering the passage of produced between closed volumes. Furthermore, the movement of the doors within an enclosure also has the drawback of generating turbulence under the laminar flow, which turbulence breaks the intangible protection barrier of the process created by the laminar flow and therefore generates a risk of contamination of the laminar flow. process.
[008] Afin de palier à la problématique d’entrave au passage des produits d’un volume à l’autre, il a été proposé dans la demande de brevet EP2504102 un arrangement de porte offrant un angle d’ouverture de porte supérieur à celui obtenu avec l’arrangement de porte susmentionné. En particulier, la porte peut être disposée, à l’état ouvert, dans une position sensiblement parallèle à l’ouverture de passage. Pour ce faire, la porte peut être écartée de la bride selon un mouvement de translation initial le long d’un axe orthogonal à l’ouverture, à la bride et à la position de la porte à son état fermé, suivi d’un mouvement ultérieur de rotation autour d’un axe orthogonal. De manière alternative, la porte peut être également écartée selon un mouvement de rotation initial autour d’un axe parallèle à l’ouverture, à la bride et à la position de la porte à l’état fermé suivi d’un mouvement ultérieur de rotation autour d’un axe parallèle à l’ouverture, à la bride et à la position de la porte à l’état fermé. In order to overcome the problem of hindering the passage of products from one volume to another, it has been proposed in patent application EP2504102 a door arrangement offering a door opening angle greater than that obtained with the aforementioned door arrangement. In particular, the door can be arranged, in the open state, in a position substantially parallel to the passage opening. To do this, the door can be moved away from the flange with an initial translational movement along an axis orthogonal to the opening, to the flange and to the position of the door in its closed state, followed by a movement subsequent rotation around an orthogonal axis. Alternatively, the door can also be moved apart according to an initial rotational movement around an axis parallel to the opening, to the flange and the position of the door in the closed state followed by a subsequent rotational movement about an axis parallel to the opening, the flange and the position of the door in the closed state.
[009] Un tel arrangement de porte présente cependant l’inconvénient de requérir un système d’entrainement de la porte traversant la paroi de l’enceinte, imposant des contraintes structurelles pour préserver l’étanchéité de l’enceinte dans le cas d’un mouvement initial de translation, ou bien l’inconvénient de générer des turbulences comme les arrangements de porte décrits précédemment dans le cas d’un mouvement initial de rotation. [009] Such a door arrangement, however, has the drawback of requiring a system for driving the door passing through the wall of the enclosure, imposing structural constraints to preserve the tightness of the enclosure in the case of a initial translational movement, or the drawback of generating turbulence such as the door arrangements described above in the case of an initial rotational movement.
[0010] L’invention vise à remédier à ces problèmes en proposant un arrangement de porte offrant une ouverture optimale de sorte à dégager l’ouverture de passage de l’enceinte tout en limitant les turbulences sous flux laminaire lors de l’ouverture de la porte. The invention aims to remedy these problems by providing a door arrangement offering an optimal opening so as to clear the passage opening of the enclosure while limiting the turbulence under laminar flow during the opening of the chamber. door.

To this end, and according to a first aspect, the invention provides a door arrangement allowing a sealed transfer between two closed volumes, comprising a flange arranged to define an opening in one of the closed volumes, the opening of passage defining an opening plane and a passage axis perpendicular to the opening plane, and an axis door hingedly mounted on the flange so as to pass from a closed position in which the door closes the opening of passage, and an open position, the door arrangement being remarkable in that the door is fixed to the flange via a double-hinged linkage mechanism comprising a first hinge arranged to allow rotational movement around it.

DESCRIPTION DETAILLEE DE L’INVENTION DETAILED DESCRIPTION OF THE INVENTION
[0019] En relation avec les figures 1 à 8, il est décrit un arrangement de porte 1 équipant un premier volume clos. Cet arrangement de porte est aménagé pour permettre le raccordement d’un deuxième volume clos. Avantageusement, le premier volume clos est une enceinte fixe tandis que le deuxième volume clos est un conteneur transportable. Il s’agit bien entendu d’un exemple de réalisation, le dispositif selon l’invention n’étant pas limité à ce type de volumes clos. L’arrangement de porte du premier volume et l’arrangement de porte du deuxième volume forment, lorsque qu’ils sont raccordés l’un à l’autre, un dispositif de fonction étanche permettant le transfert de produits entre les deux volume clos, sans rupture du confinement. In relation to Figures 1 to 8, there is described a door arrangement 1 fitted to a first closed volume. This door arrangement is arranged to allow the connection of a second closed volume. Advantageously, the first closed volume is a fixed enclosure while the second closed volume is a transportable container. This is of course an exemplary embodiment, the device according to the invention not being limited to this type of closed volumes. The door arrangement of the first volume and the door arrangement of the second volume form, when they are connected to each other, a sealed function device allowing the transfer of products between the two closed volumes, without breach of containment.
[0020] L’arrangement de porte 1 selon l’invention comporte une bride 2 et une porte 4. La bride 2 est arrangée pour délimiter une ouverture de passage 3 dans l’enceinte pourvue de l’arrangement de porte 1, l’ouverture de passage 3 définissant un plan d’ouverture et un axe de passage perpendiculaire au plan d’ouverture, et une porte 4 fixée de manière articulée sur la bride 2 de sorte à passer d’une position fermée dans laquelle la porte 4 obture l’ouverture de passage 3 à une position ouverte dans laquelle la porte 4 s’étend sensiblement parallèlement au plan d’ouverture de passage, et inversement. Pour ce faire, la porte est fixée sur la bride par l’intermédiaire d’un mécanisme de liaison 5 à double articulation. Ce dernier comporte ainsi une première articulation 6 arrangée pour permettre un mouvement de rotation autour d’un axe A perpendiculaire à l’axe C de la porte (ou à l’axe de l’ouverture de passage) d’une part et une deuxième articulation 7 arrangée pour permettre un mouvement de rotation autour d’un axe B parallèle à l’axe C de la porte (ou à l’axe de passage de l’ouverture de passage) d’autre part (figure 1). Dans la présente description, on désigne par « axe de la porte » l’axe qui s’étend perpendiculairement à la porte lorsque celle- ci est en position fermée. L’axe de la porte correspond donc à l’axe de passage de l’ouverture de passage 3. L’axe C représenté sur la figure 1 désignera par la suite indifféremment l’axe de la porte en position fermée et l’axe de passage. The door arrangement 1 according to the invention comprises a flange 2 and a door 4. The flange 2 is arranged to define a passage opening 3 in the enclosure provided with the door arrangement 1, the opening passage 3 defining an opening plane and a passage axis perpendicular to the opening plane, and a door 4 fixed in an articulated manner on the flange 2 so as to pass from a closed position in which the door 4 closes the passage opening 3 to an open position in which the door 4 extends substantially parallel to the passage opening plane, and vice versa. To do this, the door is fixed to the flange by means of a link mechanism 5 with double articulation. The latter thus comprises a first articulation 6 arranged to allow a rotational movement around an axis A perpendicular to the axis C of the door (or to the axis of the passage opening) on the one hand and a second joint 7 arranged to allow a rotational movement around an axis B parallel to the axis C of the door (or to the axis of passage of the passage opening) on the other hand (figure 1). In the present description, the term “door axis” denotes the axis which extends perpendicularly to the door when the latter is in the closed position. The axis of the door therefore corresponds to the axis of passage of the passage opening 3. The axis C shown in FIG. 1 will subsequently denote either the axis of the door in the closed position and the axis of passage.
[0021] Les deux articulations 6 et 7 sont arrangées avec la porte 4 pour que l’ouverture de la porte s’effectue en premier lieu suivant le mouvement de rotation autour de l’axe A puis en deuxième lieu suivant le mouvement de rotation autour de l’axe B. La première articulation 6 se présente sous la forme d’une charnière dont la partie fixe est solidaire de la deuxième articulation 7 qui est quant à elle couplée à la porte par un bras de raccordement 9. The two joints 6 and 7 are arranged with the door 4 so that the opening of the door is carried out firstly according to the rotational movement around the axis A and then secondly according to the rotational movement around of the axis B. The first articulation 6 is in the form of a hinge, the fixed part of which is integral with the second articulation 7 which is in turn coupled to the door by a connection arm 9.
[0022] La première articulation 6 est arrangée pour permettre un mouvement de rotation d’au plus de 30 degrés par rapport au plan de l’ouverture tandis que la deuxième articulation 7 est arrangée pour permettre un mouvement de rotation compris d’au moins 45 degrés, et de préférence de 180 degrés par rapport au plan de l’ouverture. The first articulation 6 is arranged to allow a rotational movement of at most 30 degrees relative to the plane of the opening while the second articulation 7 is arranged to allow a rotational movement of at least 45 degrees, and preferably 180 degrees from the plane of the opening.
[0023] Les figures 2 à 5 illustrent les mouvements de rotation de la porte effectués pour passer d’une position fermée à une position ouverte. Ainsi, l’ouverture de la porte 4 s’effectue, depuis sa position fermée (figure 2), par rotation autour de l’axe A de la charnière (première articulation 5) suivant une course de 20 degrés environ dans l’exemple illustré (figure 3). La porte 4 est alors dans une position d’ouverture partielle. La porte 4 est ensuite actionnée pour se mouvoir en rotation autour de l’axe B de la deuxième articulation 7 sur une course de 180 degrés environ pour parvenir à la position d’ouverture finale illustrée sur la figure 5 en passant par des positions d’ouverture intermédiaires offrant un dégagement complet de l’ouverture de passage 3 (la figure 4 montre la porte dans une position d’ouverture intermédiaire). Dans sa position finale, la porte s’étend dans un plan parallèle au plan de l’ouverture de passage, diamétralement opposée à sa position fermée. [0023] Figures 2 to 5 illustrate the rotational movements of the door made to go from a closed position to an open position. Thus, the opening of the door 4 is effected, from its closed position (FIG. 2), by rotation about the axis A of the hinge (first articulation 5) following a stroke of approximately 20 degrees in the example illustrated. (figure 3). Door 4 is then in a partially open position. The door 4 is then actuated to move in rotation around the axis B of the second articulation 7 over a stroke of approximately 180 degrees to reach the final open position illustrated in FIG. 5 passing through positions of intermediate opening offering complete clearance of the passage opening 3 (figure 4 shows the door in an intermediate opening position). In its final position, the door extends in a plane parallel to the plane of the passage opening, diametrically opposed to its closed position.
[0024] Selon un mode de réalisation avantageux, la porte est avantageusement motorisée. Pour faire, les première et deuxième articulations 6 sont couplées chacune à un moteur du type par exemple pas à pas. Il est bien entendu évident que l’invention ne se limite pas à une porte motorisée, le mouvement de cette dernière pouvant être réalisée manuellement par actionnement d’un levier de commande porté par la porte, ce levier de commande pouvant être prévu côté intérieur et/ou côté extérieur du volume clos. According to an advantageous embodiment, the door is advantageously motorized. To do this, the first and second articulations 6 are each coupled to a motor of the type for example stepping. It is of course obvious that the invention is not limited to a motorized door, the movement of the latter being able to be carried out manually by actuation of a control lever carried by the door, this control lever being able to be provided on the inside and / or outside of the closed volume.
[0025] Comme indiqué précédemment, l’arrangement de porte selon l’invention permet le couplage d’un deuxième volume pourvu d’une deuxième bride délimitant une ouverture de passage dans le deuxième volume clos et obturée par une deuxième porte. A cet effet, la bride 2 présente avantageusement une face extérieure 20 pourvue de moyens de solidarisation aptes à solidariser et maintenir la bride de la porte du deuxième volume clos plaquée contre elle. Dans le mode de réalisation illustré, les moyens de solidarisation de la bride comportent des taquets de verrouillage 8 magnétique. Il est bien entendu évident qu’il s’agit d’un exemple de réalisation et que d’autres moyens de verrouillage peuvent être mis en œuvre, comme par exemple des actionneurs, sans sortir du cadre de l’invention. As indicated above, the door arrangement according to the invention allows the coupling of a second volume provided with a second flange defining a passage opening in the second closed volume and closed by a second door. To this end, the flange 2 advantageously has an outer face 20 provided with securing means capable of securing and maintaining the flange of the door of the second closed volume pressed against it. In the illustrated embodiment, the means for securing the flange comprise magnetic locking tabs 8. It is of course obvious that this is an exemplary embodiment and that other locking means can be implemented, such as actuators, for example, without departing from the scope of the invention.
[0026] Chaque taquet de verrouillage 8 est pourvu d’un ergot de verrouillage 10 mobile entre une position dans laquelle l’ergot est en retrait au sein de la bride et une position dans laquelle l’ergot saillit radialement de la bride 2 vers l’ouverture de passage, verrouillant ainsi la bride du deuxième volume clos. Par ailleurs, chaque taquet de verrouillage 8 est associé à un micromoteur apte à les entraîner en rotation pour les faire passer de leur état non verrouillé à leur état verrouillé. Les figures 7a et 7b montrent un taquet dans sa position de dé verrouillage et sa position de verrouillage. Each locking lug 8 is provided with a locking lug 10 movable between a position in which the lug is recessed within the flange and a position in which the lug projects radially from the flange 2 towards the 'passage opening, thus locking the flange of the second closed volume. Furthermore, each locking latch 8 is associated with a micromotor capable of driving them in rotation to change them from their unlocked state to their locked state. Figures 7a and 7b show a cleat in its unlocked position and its locked position.
[0027] Dans le mode de réalisation illustré, la bride est pourvue de quatre taquets de verrouillage 8 répartis à 90 degrés. Il s’agit bien entendu d’un exemple de réalisation, le nombre de taquets de verrouillage pouvant varier selon les dimensions de la porte. La bride comporte ainsi a minima deux taquets de verrouillage, situés avantageusement diamétralement opposés l’un de l’autre. In the illustrated embodiment, the flange is provided with four locking tabs 8 distributed at 90 degrees. This is of course an exemplary embodiment, the number of locking tabs may vary depending on the dimensions of the door. The flange thus comprises at least two locking tabs, advantageously located diametrically opposed to each other.
[0028] Suivant la figure 8, la porte 4 effectue une rotation autour de l’axe C (avantageusement de 60°) pour déverrouiller la porte du deuxième volume clos de la bride de celui-ci et de solidariser la porte du deuxième volume clos avec la porte 4. Dans le mode de réalisation illustré, la porte est entraînée par un moteur situé dans le bras de raccordement 9 et parallèle à l’axe C. [0029] L’invention est décrite dans ce qui précède à titre d’exemple. Il est entendu que l’homme du métier est à même de réaliser différentes variantes de réalisation de l’invention sans pour autant sortir du cadre de l’invention. According to Figure 8, the door 4 rotates around the axis C (preferably 60 °) to unlock the door of the second closed volume of the flange thereof and to secure the door of the second closed volume with the door 4. In the illustrated embodiment, the door is driven by a motor located in the connection arm 9 and parallel to the axis C. The invention is described in the above by way of example. It is understood that a person skilled in the art is in a position to produce various variant embodiments of the invention without, however, departing from the scope of the invention.
