Description

La présente invention a pour objet un dispositif de remplissage, pour machines à remplir des récipients, du type à contre-pression.The subject of the present invention is a filling device, for machines for filling containers, of the backpressure type.

On connaît, par exemple par le brevet FR 2 075 635, un dispositif de remplissage à contre-pression selon le préambule de la revendication 1 dans lequel le remplissage et l'arrêt du remplissage sont commandés par un commutateur d'approche et une sonde électrique.Is known, for example from patent FR 2 075 635, a back-pressure filling device according to the preamble of claim 1 in which filling and stopping of filling are controlled by an approach switch and an electrical probe .

Dans ce dispositif, lors de l'ascension de la bouteille à remplir, celle-ci vient en contact par son col avec la garniture d'étanchéité d'une tulipe de centrage mobile verticalement. La bouteille continuant son ascension, la tulipe excite un commutateur d'approche. Celui-ci, relié électriquement à une électro-vanne, excite cette dernière qui réalise alors une différence de pression entre deux surfaces opposées d'un manchon coulissant verticalement. Ceci entraîne l'ascension du manchon qui libère un orifice annulaire par lequel le gaz sous pression, provenant de la cuve de remplissage, vient mettre la bouteille à remplir sous pression. Quand la bouteille est à la même pression que la cuve de remplissage, un deuxième manchon coulissant se soulève et libère un deuxième orifice annulaire par lequel le liquide à soutirer peut s'écouler dans la bouteille.In this device, during the ascent of the bottle to be filled, it comes into contact by its neck with the seal of a vertically movable centering tulip. As the bottle continues to rise, the tulip excites an approach switch. The latter, electrically connected to a solenoid valve, excites the latter which then produces a pressure difference between two opposite surfaces of a sleeve sliding vertically. This causes the sleeve to rise, which releases an annular orifice through which the pressurized gas, coming from the filling tank, comes to put the bottle to be filled under pressure. When the bottle is at the same pressure as the filling tank, a second sliding sleeve lifts up and releases a second annular orifice through which the liquid to be drawn can flow into the bottle.

Mais un dispositif de ce type, s'il permet par la commande électrique du remplissage de s'affranchir de l'utilisation de ressorts tarés de façon très précise, nécessite l'utilisation de très nombreuses pièces mécaniques mobiles, telles que des ressorts et des manchons coulissants, avec lesquelles le gaz provenant du réservoir sous pression aussi bien que le liquide à soutirer sont en contact. Ce dispositif nécessite donc, d'une part, la mise en place de très nombreux joints d'étanchéité et, d'autre part, des lavages fréquents du dispositif de soutirage pour assurer une hygiène parfaite. Par ailleurs, compte tenu des efforts nécessaires à l'ascension des manchons coulissants, il est nécessaire de relier l'électro-vanne à une source de gaz à une pression supérieure à la pression régnant dans la cuve d'alimentation.However, a device of this type, if it makes it possible, by electrical control of filling, to dispense with the use of calibrated springs very precisely, requires the use of a large number of movable mechanical parts, such as springs and sliding sleeves, with which the gas from the pressure tank as well as the liquid to be drawn off are in contact. This device therefore requires, on the one hand, the installation of very many seals and, on the other hand, frequent washing of the racking device to ensure perfect hygiene. Furthermore, taking into account the efforts necessary for the ascent of the sliding sleeves, it is necessary to connect the solenoid valve to a source of gas at a pressure higher than the pressure prevailing in the supply tank.

La présente invention a donc pour but la réalisation d'un dispositif de remplissage du type à contre-pression, dans lequel le début et l'arrêt du remplissage sont commandés électriquement, et dans lequel le liquide à soutirer n'est en contact avec aucune pièce mécanique mobile ni avec aucun joint d'étanchéité.The present invention therefore aims to achieve a filling device of the backpressure type, in which the start and stop of the filling are electrically controlled, and in which the liquid to be drawn is not in contact with any moving mechanical part or with no seal.

Un autre but de l'invention est la réalisation d'un dispositif de soutirage du type décrit ci- dessus dans lequel la seule source de gaz sous pression utilisée est constituée par le réservoir d'alimentation en liquide sous pression.Another object of the invention is the production of a withdrawal device of the type described above in which the only source of pressurized gas used is constituted by the tank for supplying pressurized liquid.

La présente invention a donc pour objet -un dispositif de remplissage du type de celui décrit dans la revendication 1 de la présente demande.The present invention therefore relates to a filling device of the type described in claim 1 of the present application.

Selon l'exemple de réalisation représenté à la Fig. 1, le dispositif de remplissage A, selon l'invention, est destiné à remplir, à partir d'une cuve B d'alimentation en liquide sous pression de gaz, un récipient C, en matière plastique ou autre matériau, porté par un dispositif de levage D.According to the exemplary embodiment shown in FIG. 1, the filling device A, according to the invention, is intended to fill, from a tank B for supplying liquid under gas pressure, a container C, made of plastic or other material, carried by a device lifting D.

Comme illustré à la Fig. 2, le dispositif de remplissage A selon l'invention est constitué d'un corps 1, cylindrique d'axe X-X, d'une sonde électrique 2, coaxiale traversant le corps 1 sur toute sa hauteur, d'un dispositif 3 de réglage de la position de la sonde 2 par rapport au corps 1, d'un manchon 4 d'axe X-X, à l'intérieur du corps 1, et de deux membranes 5 et 6 d'axe X-X.As illustrated in Fig. 2, the filling device A according to the invention consists of a body 1, cylindrical with axis XX, of an electrical probe 2, coaxial passing through the body 1 over its entire height, of a device 3 for adjusting the position of the probe 2 relative to the body 1, of a sleeve 4 of axis XX, inside the body 1, and of two membranes 5 and 6 of axis XX.

Comme illustré Fig. 3, le corps 1, cylindrique d'axe vertical X-X, est percé, à son extrémité supérieure, d'un conduit cylindrique vertical 7, d'axe X-X, et, à son extrémité inférieure, d'un deuxième conduit cylindrique 8, vertical d'axe X-X. Le conduit vertical inférieur 8 se termine, à son extrémité située du côté de la base du corps 1, par une garniture d'étanchéité 9, d'axe X-X. Cette garniture d'étanchéité 9 présente une face interne 10, tronconique convergente vers le sommet du corps, dont le diamètre interne minimum est inférieur ou égal au diamètre interne du conduit 8.As illustrated in Fig. 3, the body 1, cylindrical with vertical axis XX, is pierced, at its upper end, with a vertical cylindrical conduit 7, with axis XX, and, at its lower end, with a second cylindrical conduit 8, vertical of axis XX. The lower vertical duct 8 ends, at its end situated on the side of the base of the body 1, by a sealing gasket 9, of axis X-X. This seal 9 has an internal face 10, frustoconical converging towards the top of the body, the minimum internal diameter of which is less than or equal to the internal diameter of the conduit 8.

Le conduit supérieur 7, par son extrémité inférieure, ainsi que le conduit inférieur 8, par son extrémité supérieure, débouchent dans une chambre 11 limitée par une paroi cylindrique 12 d'axe X-X.The upper duct 7, through its lower end, as well as the lower duct 8, through its upper end, open into a chamber 11 limited by a cylindrical wall 12 of axis X-X.

Cette chambre 11 est limitée à son extrémité inférieure par une surface annulaire 13. Dans l'exemple de réalisation représenté Fig. 3, cette surface 13 est de section droite mais elle pourrait être d'une section courbe. Cette surface 13 est raccordée vers l'intérieur de la chambre 11, en direction de l'axe X-X, à une surface 14, de révolution d'axe X-X. Sur l'exemple de réalisation représenté plus particulièrement Fig.3, cette surface 14 est tronconique convergente vers le haut du corps. 1. Ainsi la surface 14 se raccorde par son extrémité supérieure à l'extrémité supérieure du conduit 8 par l'intermédiaire d'une surface annulaire 15, qui peut être plane ou courbe.This chamber 11 is limited at its lower end by an annular surface 13. In the embodiment shown in FIG. 3, this surface 13 is of cross section but it could be of a curved section. This surface 13 is connected towards the inside of the chamber 11, in the direction of the axis X-X, to a surface 14, of revolution of axis X-X. In the embodiment shown more particularly in Fig.3, this surface 14 is frustoconical converging towards the top of the body. 1. Thus the surface 14 is connected by its upper end to the upper end of the conduit 8 via an annular surface 15, which can be flat or curved.

Les surfaces 14, 15 et 8 délimitent donc une paroi 16, la cote de la surface 15 par rapport à la base du corps 1 étant supérieure à la cote de la surface 13 par rapport à la base du corps 1.The surfaces 14, 15 and 8 therefore delimit a wall 16, the dimension of the surface 15 relative to the base of the body 1 being greater than the dimension of the surface 13 relative to the base of the body 1.

A peu près à mi-hauteur de la paroi cylindrique 12 est ménagée une gorge annulaire 17. La cote de la gorge annulaire 17 par rapport à la base du corps 1 est supérieure à la cote de la surface annulaire 15 par rapport à la base du corps 1.About halfway up the cylindrical wall 12 is formed an annular groove 17. The dimension of the annular groove 17 relative to the base of the body 1 is greater than the dimension of the annular surface 15 relative to the base of the body 1.

Au voisinage de l'extrémité supérieure de la paroi 12 est ménagée une deuxième gorge annulaire 18 dans cette paroi 12.In the vicinity of the upper end of the wall 12 is formed a second annular groove 18 in this wall 12.

L'extrémité supérieure de la paroi 12 est raccordée à l'extrémité inférieure du canal 7 par une surface 19, de révolution d'axe X-X, constituant le plafond de la chambre 11. Sur l'exemple de réalisation représenté plus particulièrement Fig. 3, cette surface 19 est tronconique convergente vers le sommet du corps 1.The upper end of the wall 12 is connected to the lower end of the channel 7 by a surface 19, of axis X-X revolution, constituting the ceiling of the chamber 11. In the embodiment shown more particularly in FIG. 3, this surface 19 is frustoconical converging towards the top of the body 1.

Une chambre annulaire 20, d'axe X-X, est ménagée dans ce plafond 19.An annular chamber 20, of axis X-X, is provided in this ceiling 19.

Comme on le voit plus particulièrement Fig. 3, un conduit 21 est percé à l'extrémité supérieure du corps 1, et débouche dans le conduit 7 à l'extrémité supérieure de celui-ci. Ce conduit 21 communique avec le conduit 7 par l'intermédiaire d'une garniture d'étanchéité 22 percée d'un orifice 23.As can be seen more particularly in FIG. 3, a conduit 21 is pierced at the upper end of the body 1, and opens into the conduit 7 at the upper end thereof. This conduit 21 communicates with the conduit 7 by means of a seal 22 pierced with an orifice 23.

Un deuxième conduit 24, percé à l'extrémité supérieure du corps 1, communique avec la chambre annulaire 20 ménagée dans le plafond 19 de la chambre 11. Deux conduits 25 et 26 relient la chambre 11 à l'extérieur du corps 1. Le conduit 25 débouche dans la chambre 11 par la paroi 12 entre la gorge annulaire 17 et le fond 13 de la chambre 11. Le conduit 26 débouche dans la chambre 11, par la paroi 12, entre les gorges annulaires 17 et 18. Ce conduit 26 présente par ailleurs une dérivation 27 qui débouche elle aussi à l'extérieur du corps 1.A second conduit 24, pierced at the upper end of the body 1, communicates with the annular chamber 20 formed in the ceiling 19 of the chamber 11. Two conduits 25 and 26 connect the chamber 11 to the exterior of the body 1. The conduit 25 opens into the chamber 11 through the wall 12 between the annular groove 17 and the bottom 13 of the chamber 11. The conduit 26 opens into the chamber 11, through the wall 12, between the annular grooves 17 and 18. This conduit 26 has moreover, a bypass 27 which also opens outside the body 1.

En outre, un anneau d'appui 28, d'axe X-X, placé en regard de la surface 15, à l'intérieur de la chambre 11, à une cote par rapport à la base du corps 1 légèrement supérieure à celle de la gorge annulaire 17, est relié à la paroi 12 de la chambre 11 par des bras 29.In addition, a support ring 28, of axis XX, placed opposite the surface 15, inside the chamber 11, at a dimension relative to the base of the body 1 slightly greater than that of the groove annular 17, is connected to the wall 12 of the chamber 11 by arms 29.

Comme on le voit Fig. 1, le conduit 26 est relié à la partie supérieure de la cuve d'alimentation B et le conduit 25 est relié à l'extrémité inférieure de la cuve d'alimentation B. Ainsi le conduit 26 est relié au gaz sous pression PO régnant dans la cuve d'alimentation alors que le conduit 25 est relié au liquide de la cuve d'alimentation B. Les conduits 24 et 27 sont reliés à une électrovanne E.As seen in Fig. 1, the conduit 26 is connected to the upper part of the supply tank B and the conduit 25 is connected to the lower end of the supply tank B. Thus the conduit 26 is connected to the pressurized gas PO prevailing in the supply tank while the pipe 25 is connected to the liquid in the supply tank B. The pipes 24 and 27 are connected to a solenoid valve E.

Enfin, un détecteur de proximité P, du récipient C à remplir, est placé sur le dispositif de remplissage A selon l'invention. Sur l'exemple de réalisation représenté Fig. 1, ce détecteur de proximité est fixé au mrps 1, mais il pourrait être indépendant de ce corps 1 et placé, par exemple, sur le dispositif de levage D.Finally, a proximity detector P, of the container C to be filled, is placed on the filling device A according to the invention. In the embodiment shown in FIG. 1, this proximity detector is fixed to the mrps 1, but it could be independent of this body 1 and placed, for example, on the lifting device D.

Comme on le voit plus particulièrement Fig. 2, le dispositif de réglage en hauteur de la sonde électrique 2 est constitué d'un socle 30 d'axe X-X, percé d'un orifice vertical 31 de guidage cylindrique d'axe X-X. Ce socle 30 présente, à une surface inférieure 32, un prolongement inférieur 33 d'axe X-X relié à cette surface inférieure 32 et présentant un flanc constitué d'une surface cylindrique 34. Le prolongement 33, comme le socle 30, est percé de l'orifice vertical de guidage 31. Le socle 30 est disposé à l'extrémité supérieure du conduit 7 et centré sur cette extrémité par un épaulement 46 de diamètre externe correspondant au diamètre interne du conduit 7. Cet épaulement 46 est ménagé à la surface inférieure 32 du socle 30. La surface cylindrique 34 présente une garniture d'étanchéité 47 de diamètre externe inférieur au diamètre interne du conduit 7.As can be seen more particularly in FIG. 2, the height adjustment device of the electric probe 2 consists of a base 30 of axis X-X, pierced with a vertical orifice 31 of cylindrical guide of axis X-X. This base 30 has, at a lower surface 32, a lower extension 33 of axis XX connected to this lower surface 32 and having a flank consisting of a cylindrical surface 34. The extension 33, like the base 30, is pierced with the vertical guide hole 31. The base 30 is disposed at the upper end of the duct 7 and centered on this end by a shoulder 46 of external diameter corresponding to the internal diameter of the duct 7. This shoulder 46 is formed on the lower surface 32 of the base 30. The cylindrical surface 34 has a seal 47 with an external diameter less than the internal diameter of the duct 7.

Une garniture d'étanchéité torique 35 est placée dans un logement 36 ménagé à l'intérieur du socle 30 dans la surface cylindrique de l'orifice vertical de guidage 31.An O-ring seal 35 is placed in a housing 36 formed inside the base 30 in the cylindrical surface of the vertical guide orifice 31.

Le socle 30 présente une potence 37 dont un bras horizontal 38 est percé d'un orifice 39 à travers lequel passe une tige de réglage 40.The base 30 has a bracket 37, a horizontal arm 38 of which is pierced with an orifice 39 through which an adjustment rod 40 passes.

La sonde électrique 2 est contenue, sur la majorité de sa longueur, sauf à son extrémité inférieure, à l'intérieur d'une gaine 41. L'extrémité supérieure de la gaine 41 est contenue à l'intérieur d'un capuchon d'appui 42 auquel elle est fixée.The electrical probe 2 is contained, over the majority of its length, except at its lower end, inside a sheath 41. The upper end of the sheath 41 is contained inside a cap. support 42 to which it is fixed.

Comme on le voit plus particulièrement Fig. 2, le capuchon d'appui 42 est en contact, par sa face supérieure, avec l'extrémité inférieure de la tige de réglage 40, et, par son extrémité inférieure, avec un ressort 43 qui appuie à la fois sur l'extrémité inférieure du capuchon d'appui 42 et sur la surface supérieure du socle 30.As can be seen more particularly in FIG. 2, the support cap 42 is in contact, by its upper face, with the lower end of the adjustment rod 40, and, by its lower end, with a spring 43 which bears both on the lower end of the support cap 42 and on the upper surface of the base 30.

La sonde électrique 2 et la gaine 41 traversent le socle 30 par l'orifice 31, la garniture d'étanchéité 35 étant appliquée contre la surface externe de la gaine 41.The electrical probe 2 and the sheath 41 pass through the base 30 through the orifice 31, the seal 35 being applied against the external surface of the sheath 41.

L'extrémité supérieure de la sonde 2 est reliée à deux circuits électriques 44 et 45 situés dans le capuchon d'appui 42.The upper end of the probe 2 is connected to two electrical circuits 44 and 45 located in the support cap 42.

Ces circuits électriques 44 et 45 relient la sonde électrique 2 avec l'électrovanne E.These electrical circuits 44 and 45 connect the electrical probe 2 with the solenoid valve E.

Le manchon 4, de révolution d'axe X-X, est constitué d'une surface externe cylindrique 47, de diamètre externe correspondant au diamètre interne du conduit 7, qui se raccorde vers le bas, par un épaulement 48, à une deuxième surface cylindrique 49 de diamètre externe inférieur au diamètre externe de la surface 47. En-dessous de cette surface cylindrique 49 est ménagée une surface d'ancrage sous la forme d'une gorge 50, poursuivie vers le bas par une structure de guidage 51. Cette structure de guidage 51 peut être constituée, comme illustré plus particulièrement Fig. 2, par un corps cylindrique 52 présentant à sa surface externe des saillies longitudinales verticales 53.The sleeve 4, of revolution of axis XX, consists of a cylindrical external surface 47, of external diameter corresponding to the internal diameter of the duct 7, which is connected downwards, by a shoulder 48, to a second cylindrical surface 49 of external diameter smaller than the external diameter of the surface 47. Below this cylindrical surface 49 is provided an anchoring surface in the form of a groove 50, continued downwards by a guide structure 51. This structure of guide 51 can be formed, as illustrated more particularly in FIG. 2, by a cylindrical body 52 having on its outer surface vertical longitudinal projections 53.

Le manchon 4 présente intérieurement une surface cylindrique 54 d'axe X-X, sur une hauteur correspondant à la hauteur de la surface 47, reliée vers le bas, par une surface annulaire d'appui 55, à un conduit cylindrique vertical 56 d'axe X-X de diamètre supérieur au diamètre externe de la gaine 41.The sleeve 4 has internally a cylindrical surface 54 of axis XX, over a height corresponding to the height of the surface 47, connected downwards, by an annular bearing surface 55, to a vertical cylindrical conduit 56 of axis XX of diameter greater than the external diameter of the sheath 41.

Comme on le voit plus particulièrement Fig. 2, la surface 47 est destinée à venir en contact, avec glissement, avec la surface interne du conduit 7. Par ailleurs, la base de la gorge 50 est située, quand le dispositif de remplissage selon l'invention est au repos, à une hauteur, par rapport à la base du corps 1, correspondant à la hauteur de la surface 15 par rapport à la base du corps 1. Le dispositif de guidage 51 s'étend, au repos et dans le sens vertical, de la surface 15 de la paroi 16 à la base de la garniture d'étanchéité 9.As can be seen more particularly in FIG. 2, the surface 47 is intended to come into contact, with sliding, with the internal surface of the duct 7. Furthermore, the base of the groove 50 is located, when the filling device according to the invention is at rest, at a height, relative to the base of the body 1, corresponding to the height of the surface 15 relative to the base of the body 1. The guide device 51 extends, at rest and in the vertical direction, from the surface 15 the wall 16 at the base of the gasket 9.

La membrane 5, d'axe X-X, en élastomère ou en un autre matériau déformable, présente un rebord annulaire externe 57 destiné à venir se loger dans la gorge annulaire 18 de la paroi cylindrique 12 du corps 1.The membrane 5, of axis X-X, made of elastomer or another deformable material, has an external annular rim 57 intended to be received in the annular groove 18 of the cylindrical wall 12 of the body 1.

Le rebord annulaire 57 est prolongé, vers l'axe X-X, par une paroi 58 jusqu'au manchon 4. Dans l'exemple de réalisation représenté plus particulièrement Fig. 2, cette paroi 58 présente, au repos, une forme tronconique convergente vers la base de corps 1.The annular rim 57 is extended, towards the axis X-X, by a wall 58 up to the sleeve 4. In the embodiment shown more particularly in FIG. 2, this wall 58 has, at rest, a frustoconical shape converging towards the base of body 1.

Cette paroi 58 se prolonge par un corps d'ancrage 59 qui s'étend de la base de la surface cylindrique 47 du manchon 4 jusqu'à la gorge 50. La surface interne de ce corps d'ancrage 59 présente un profil correspondant à celui de la surface externe du manchon coulissant 4 sur lequel il est fixé.This wall 58 is extended by an anchoring body 59 which extends from the base of the cylindrical surface 47 of the sleeve 4 to the groove 50. The internal surface of this anchoring body 59 has a profile corresponding to that of the external surface of the sliding sleeve 4 on which it is fixed.

La base du corps d'ancrage 59, au niveau de la gorge 50, est constituée par une surface tronconique 60 convergente vers la base du corps 1.The base of the anchoring body 59, at the level of the groove 50, is constituted by a frustoconical surface 60 converging towards the base of the body 1.

La membrane 6, d'axe. X-X, en élastomère ou autre matériau déformable, présente un rebord annulaire externe 61, destiné à venir se loger dans la gorge annulaire 17 de la paroi cylindrique 12 du corps 1.The membrane 6, of axis. X-X, made of elastomer or other deformable material, has an external annular rim 61, intended to be received in the annular groove 17 of the cylindrical wall 12 of the body 1.

Le rebord annulaire 61 est prolongé, vers l'axe X-X, par une paroi 62. Cette paroi 62 se raccorde, vers le bas, par sa surface inférieure, à une surface externe d'un corps vertical 63 d'axe X-X, par l'intermédiaire d'une surface de révolution 64, tronconique dans l'exemple de réalisation présenté Fig. 2, convergente vers la base du corps 1.The annular rim 61 is extended, towards the axis XX, by a wall 62. This wall 62 is connected, downwards, by its lower surface, to an external surface of a vertical body 63 of axis XX, by l intermediary of a surface of revolution 64, frustoconical in the embodiment shown in FIG. 2, converging towards the base of the body 1.

Ainsi, le dispositif de remplissage une fois monté présente une sonde électrique 2 d'axe X-X, située à l'intérieur d'une gaine 41 d'axe X-X et traversant l'orifice 31 du socle 30. Cette sonde électrique 2 traverse alors le conduit 7 et le manchon coulissant 4, par le conduit 56, débouchant alors à la base du corps 1 en-dessous de celui-ci.Thus, the filling device once mounted has an electrical probe 2 of axis XX, located inside a sheath 41 of axis XX and passing through the orifice 31 of the base 30. This electrical probe 2 then passes through the conduit 7 and the sliding sleeve 4, through conduit 56, then opening at the base of the body 1 below the latter.

Le manchon 4, solidaire de la membrane 5 par l'intermédiaire du corps d'ancrage 59, de l'épaulement 48 de la surface cylindrique 49 et de la gorge d'ancrage 50, est monté coulissant selon l'axe X-X à l'intérieur du conduit 7, par contact de la surface du conduit 7 avec la surface cylindrique externe 47 du manchon 4.The sleeve 4, integral with the membrane 5 via the anchoring body 59, the shoulder 48 of the cylindrical surface 49 and the anchoring groove 50, is slidably mounted along the axis XX to the inside the duct 7, by contact of the surface of the duct 7 with the external cylindrical surface 47 of the sleeve 4.

La membrane 6, fixée par son rebord annulaire 61 au corps 1, est en appui, au repos, par sa surface de révolution 64 contre la surface 15 de la paroi 16 du corps 1.The membrane 6, fixed by its annular rim 61 to the body 1, is in abutment, at rest, by its surface of revolution 64 against the surface 15 of the wall 16 of the body 1.

Cette membrane 6, d'axe X-X, entoure le dispositif de guidage 51 du manchon 4, son conduit 65 vertical d'axe X-X étant d'un diamètre correspondant, ou légèrement supérieur, au diamètre externe des saillies longitudinales verticales de guidage 53.This membrane 6, of axis X-X, surrounds the guide device 51 of the sleeve 4, its vertical duct 65 of axis X-X being of a diameter corresponding to, or slightly greater, than the external diameter of the vertical longitudinal guide projections 53.

Ainsi, la membrane 6 délimite, par son conduit intérieur 65, des conduits longitudinaux verticaux 76 avec le corps de guidage 51, le diamètre du corps cylindrique 52 du dispositif de guidage 51 étant inférieur au diamètre des saillies longitudinales verticales 53.Thus, the membrane 6 delimits, by its internal duct 65, vertical longitudinal ducts 76 with the guide body 51, the diameter of the cylindrical body 52 of the guide device 51 being less than the diameter of the vertical longitudinal projections 53.

En outre, un espace annulaire 67 est ménagé entre la surface externe du corps 63 et le conduit 8 du corps 1, le diamètre externe du corps 63 étant inférieur au diamètre interne du conduit 8.In addition, an annular space 67 is formed between the external surface of the body 63 and the conduit 8 of the body 1, the external diameter of the body 63 being less than the internal diameter of the conduit 8.

Enfin un ressort 68, en appui sur la face inférieure du prolongement 33 du socle 30 et sur la face supérieure interne du manchon 4, maintient la membrane 5 en appui par sa surface tronconique 60 contre la surface tronconique correspondante 66 de la membrane 6 elle-même maintenue en appui par sa surface de révolution 64 contre la surface 15 de la paroi 16 du corps 1.Finally, a spring 68, bearing on the lower face of the extension 33 of the base 30 and on the internal upper face of the sleeve 4, keeps the membrane 5 in abutment by its frustoconical surface 60 against the corresponding frustoconical surface 66 of the membrane 6 itself even maintained in abutment by its surface of revolution 64 against the surface 15 of the wall 16 of the body 1.

Ainsi, lorsque le dispositif de remplissage A selon l'invention est au repos, celui-ci présente, de haut en bas, trois chambres annulaires 69, 70, 71. La chambre annulaire supérieure 69 est limitée par le plafond 19 de la chambre 11 et la surface supérieure de la paroi 58 de la membrane 5. La chambre annulaire médiane 70 est limitée par la surface inférieure de la paroi 58 de la membrane 5 et la surface supérieure de la paroi 62 de la membrane 6. La chambre annulaire inférieure 71 est limitée par la surface inférieure de la paroi 62 de la membrane 6 et par la surface 13 de la chambre 11.Thus, when the filling device A according to the invention is at rest, it has, from top to bottom, three annular chambers 69, 70, 71. The upper annular chamber 69 is limited by the ceiling 19 of the chamber 11 and the upper surface of the wall 58 of the membrane 5. The middle annular chamber 70 is limited by the lower surface of the wall 58 of the membrane 5 and the upper surface of the wall 62 of the membrane 6. The lower annular chamber 71 is limited by the lower surface of the wall 62 of the membrane 6 and by the surface 13 of the chamber 11.

Selon une variante de l'invention, illustrée Fig. 4, la membrane 6 peut être remplacée par une membrane 72, d'axe X-X, présentant un rebord annulaire 611 d'ancrage dans la gorge 17 du corps 1. Le rebord annulaire 611 est prolongé, vers l'axe X-X, par une paroi 621. Cette paroi 621 est rendue solidaire du corps coulissant 631, d'axe X-X. Ce corps coulissant 631 présente un conduit interne 651, cylindrique d'axe X-X, d'un diamètre correspondant au diamètre du conduit 65 du corps 63. Le conduit 651 se termine, à son extrémité supérieure, par une surface tronconique 661, convergente vers la base du corps 1, correspondant à la surface tronconique 66 de la membrane 6.According to a variant of the invention, illustrated in FIG. 4, the membrane 6 can be replaced by a membrane 72, of axis XX, having an annular flange 611 for anchoring in the groove 17 of the body 1. The annular flange 611 is extended, towards the axis XX, by a wall 621. This wall 621 is made integral with the sliding body 631, of axis XX. This sliding body 631 has an internal duct 651, cylindrical with axis XX, of a diameter corresponding to the diameter of the duct 65 of the body 63. The duct 651 ends, at its upper end, by a frustoconical surface 661, converging towards the base of the body 1, corresponding to the frustoconical surface 66 of the membrane 6.

Ainsi, la face supérieure de la membrane 72 se raccorde à la surface tronconique 661 du corps coulissant 631 et la face inférieure de la membrane 72 se raccorde à la face externe du corps coulissant 631 par un prolongement 73 de cette membrane 72, de révolution d'axe X-X. Ce prolongement 73, qui sert d'ancrage, par sa face interne, de la membrane 72 à la périphérie supérieure du corps coulissant 631, présente une surface externe 641 de révolution, d'axe X-X, qui raccorde la face externe du corps 631 avec la face inférieure de la paroi 621 de la membrane 72. Cette surface de révolution 641 présente un profil correspondant au profil de la surface 64 de la membrane 6 et est donc destinée à venir en appui sur la face supérieure 15 de la paroi 16.Thus, the upper face of the membrane 72 is connected to the frustoconical surface 661 of the sliding body 631 and the lower face of the membrane 72 is connected to the external face of the sliding body 631 by an extension 73 of this membrane 72, of revolution d 'axis XX. This extension 73, which serves to anchor, by its internal face, the membrane 72 to the upper periphery of the sliding body 631, has an external surface 641 of revolution, of axis XX, which connects the external face of the body 631 with the underside of the wall 621 of the membrane 72. This surface of revolution 641 has a profile corresponding to the profile of the surface 64 of the membrane 6 and is therefore intended to come into abutment on the upper face 15 of the wall 16.

FonctionnementOperation

Le dispositif de levage D, qui peut être une simple sellette, amène le col du récipient à remplir, C, qui peut être une bouteille en plastique ou autre matériau, contre la face tronconique 10 de la garniture d'étanchéité 9 du corps 1, qui sert en même temps à centrer le col du récipient à remplir C.The lifting device D, which can be a simple harness, brings the neck of the container to be filled, C, which can be a plastic bottle or other material, against the frustoconical face 10 of the sealing gasket 9 of the body 1, which serves at the same time to center the neck of the container to be filled C.

Le détecteur de proximité P est alors excité, ce qui actionne l'électrovanne E. Celle-ci, par le conduit 24, diminue la pression régnant dans la chambre annulaire 69. La chambre annulaire 70 étant reliée, par le conduit 26, au réservoir de gaz sous pression où règne une pression P0, cette chambre 70 est elle aussi à la pression P0. Il apparaît alors une différence de pression entre les faces supérieure et inférieure de la membrane 5. Lorsque cette différence de pression atteint une valeur suffisante prédéterminée, la membrane 5 tend à se déplacer vers le haut entraînant avec elle le manchon 4, la différence de pression étant suffisante pour comprimer le ressort 68. Le déplacement vertical est achevé lorsque la paroi 58 de la membrane 5 atteint le plafond 19 de la chambre 11 (Fig.5).The proximity detector P is then excited, which actuates the solenoid valve E. The latter, via the conduit 24, decreases the pressure prevailing in the annular chamber 69. The annular chamber 70 being connected, by the conduit 26, to the reservoir pressurized gas where there is a pressure P0, this chamber 70 is also at the pressure P0. A pressure difference then appears between the upper and lower faces of the membrane 5. When this pressure difference reaches a predetermined sufficient value, the membrane 5 tends to move upwards, bringing with it the sleeve 4, the pressure difference being sufficient to compress the spring 68. The vertical displacement is complete when the wall 58 of the membrane 5 reaches the ceiling 19 of the chamber 11 (Fig.5).

Ainsi la surface tronconique 60 de la membrane 5 n'est plus en contact avec la surface tronconique 66 (respectivement 661) de la membrane 6 (respectivement corps 631), ménageant ainsi un espace annulaire 74.Thus the frustoconical surface 60 of the membrane 5 is no longer in contact with the frustoconical surface 66 (respectively 661) of the membrane 6 (respectively body 631), thus providing an annular space 74.

Par ailleurs, la montée du manchon 4 fait que son extrémité supérieure vient en contact étanche avec la garniture 47 du socle 30. Ainsi il n'y a plus aucune relation entre le conduit 21 et l'intérieur du manchon coulissant 4.Furthermore, the rise of the sleeve 4 means that its upper end comes into leaktight contact with the lining 47 of the base 30. Thus there is no longer any relationship between the duct 21 and the interior of the sliding sleeve 4.

Le gaz contenu dans la chambre annulaire 70 peut alors, par l'espace 74 et les canaux 76, pénétrer à l'intérieur du récipient à remplir. La pression du gaz à l'intérieur du récipient, ainsi que de la cuve d'alimentation, pouvant être régulées par l'électrovanne E par l'intermédiaire du conduit 27, le gaz dans le récipient à remplir peut atteindre une pression P1 égale à la pression PO constante régnant au-dessus du liquide dans la cuve d'alimentation B.The gas contained in the annular chamber 70 can then, through the space 74 and the channels 76, penetrate inside the container to be filled. The pressure of the gas inside the container, as well as of the supply tank, being able to be regulated by the solenoid valve E via the conduit 27, the gas in the container to be filled can reach a pressure P1 equal to the constant pressure PO prevailing above the liquid in the supply tank B.

Or, dans la chambre annulaire 71, à la surface de la membrane 6, règne une pression égale à PO plus la hauteur de liquide H entre le niveau de liquide dans le réservoir en charge et le niveau de la paroi 62 de la membrane 6. Par ailleurs, sur tout le reste de la membrane 6, règne une pression égale à P0. Ainsi, par la différence de pression due à la mise en charge du réservoir par rapport au dispositif de soutirage, la membrane 6, ou. la membrane 72 et le corps 631, se soulève au-dessus de la surface 15, la surface 64, respectivement la surface 641, n'étant plus en contact avec la surface 15 (Fig. 6).However, in the annular chamber 71, at the surface of the membrane 6, there is a pressure equal to PO plus the height of liquid H between the level of liquid in the tank under load and the level of the wall 62 of the membrane 6. Furthermore, over all the rest of the membrane 6, a pressure equal to P0 prevails. Thus, by the pressure difference due to the loading of the tank relative to the withdrawal device, the membrane 6, or. the membrane 72 and the body 631, is raised above the surface 15, the surface 64, respectively the surface 641, no longer being in contact with the surface 15 (FIG. 6).

Grâce à l'anneau d'appui 28 de la chambre 11, l'ascension de la membrane 6 est limitée, ce qui fait que la surface 60 de la membrane 5 ne vient pas en contact avec la surface 66 (respectivement 661) de la membrane 6 (respectivement du corps 631). En effet, l'anneau d'appui 28 est situé, à l'intérieur de la chambre annulaire 70, en regard d'une surface 15 de la chambre 11 au-dessus de la membrane 6-72.Thanks to the support ring 28 of the chamber 11, the ascent of the membrane 6 is limited, which means that the surface 60 of the membrane 5 does not come into contact with the surface 66 (respectively 661) of the membrane 6 (respectively of the body 631). Indeed, the support ring 28 is located, inside the annular chamber 70, opposite a surface 15 of the chamber 11 above the membrane 6-72.

Une ouverture annulaire 75 est donc réalisée entre la surface 64 (respectivement la surface 641) et la surface 15 de la paroi 16.An annular opening 75 is therefore produced between the surface 64 (respectively the surface 641) and the surface 15 of the wall 16.

Le liquide contenu dans la chambre annulaire 71 en provenance de la cuve d'alimentation B, peut alors passer par le canal annulaire 67 dans la bouteille à remplir, le gaz contenu dans la bouteille étant alors évacué par les canaux 76 vers la chambre 70, l'électrovanne E assurant une pression constante.The liquid contained in the annular chamber 71 coming from the supply tank B, can then pass through the annular channel 67 in the bottle to be filled, the gas contained in the bottle then being evacuated through the channels 76 towards the chamber 70, the solenoid valve E ensuring a constant pressure.

Lorsque le liquide, à l'intérieur de la bouteille, atteint la base de la sonde 2, celle-ci, par les circuits électriques 44 et 45, inverse le fonctionnement de l'électrovanne E. Ainsi du gaz sous pression pénètre dans la chambre 20, par le conduit 24, et abaisse la membrane 5 qui entraîne avec elle le manchon coulissant 4, la surface 60 venant en contact avec la surface 66 (respectivement 661), la descente de la membrane 5 et du manchon 4 se poursuivant en entraînant ainsi la descente de la membrane 6 (respectivement de la membrane 72 et du corps 631). La surface 64 (respectivement 641) de la membrane 6 (respectivement 72) vient alors en contact avec la surface 15 de la paroi 16 (Fig. 7).When the liquid inside the bottle reaches the base of the probe 2, the latter, by the electrical circuits 44 and 45, reverses the operation of the solenoid valve E. Thus pressurized gas enters the chamber 20, by the conduit 24, and lowers the membrane 5 which drives with it the sliding sleeve 4, the surface 60 coming into contact with the surface 66 (respectively 661), the descent of the membrane 5 and of the sleeve 4 continuing by driving thus the descent of the membrane 6 (respectively of the membrane 72 and of the body 631). The surface 64 (respectively 641) of the membrane 6 (respectively 72) then comes into contact with the surface 15 of the wall 16 (Fig. 7).

Les clapets d'alimentation de la bouteille en liquide à soutirer et en gaz sous pression sont alors refermés, le remplissage est achevé.The valves for supplying the bottle with liquid to be drawn off and pressurized gas are then closed, filling is complete.

La descente du manchon 4 libère l'ouverture 23 du conduit 21 et le gaz sous pression contenu dans le récipient à remplir peut alors s'échapper par le conduit 56, le conduit 7, l'ouverture 23 de la gamiture 22 et le conduit 21. La bouteille est ainsi remise à la pression atmosphérique. Ainsi un nouveau cycle de remplissage d'un nouveau récipient peut commencer.The descent of the sleeve 4 releases the opening 23 of the conduit 21 and the pressurized gas contained in the container to be filled can then escape through the conduit 56, the conduit 7, the opening 23 of the fitting 22 and the conduit 21 The bottle is thus returned to atmospheric pressure. Thus a new filling cycle for a new container can begin.

Par ailleurs, la sonde 2, par le dispositif 3 de réglage vertical de ladite sonde 2, peut pénétrer plus ou moins à l'intérieur du récipient à remplir C, ce qui permet de modifier aisément le niveau de remplissage du récipient C.Furthermore, the probe 2, by the device 3 for vertical adjustment of said probe 2, can penetrate more or less inside the container to be filled C, which makes it possible to easily modify the filling level of the container C.

Le dispositif selon l'invention constitue donc un moyen simple pour remplir un récipient par contre-pression, le liquide à soutirer n'étant en contact avec aucune garniture d'étanchéité ni avec aucune pièce mécanique mobile.The device according to the invention therefore constitutes a simple means for filling a container by back pressure, the liquid to be drawn off not being in contact with any seal or with any moving mechanical part.
