Description

La présente invention est relative à un dispositif de remplissage pour machine à remplir des récipients avec des liquides non gazeux.The present invention relates to a filling device for a machine for filling containers with non-gaseous liquids.

La présente invention a plus particulièrement pour objet la réalisation d'un dispositif de remplissage, du type à retour d'air séparé, c'est-à-dire évitant la pollution du liquide à soutirer par l'air évacué du récipient lors de son remplissage.A more particular subject of the present invention is the production of a filling device, of the type with separate air return, that is to say avoiding pollution of the liquid to be drawn off by the air evacuated from the container during its filling.

Il est connu différents dispositifs de remplissage dans lesquels l'air contenu dans le récipient est évacué par un évent sans que cet air soit réintroduit dans la cuve d'alimentation en liquide. Mais, les dispositifs connus de ce type impliquent des pertes de liquide à soutirer qui ne sont par tolérables quand la valeur marchande du liquide à soutirer est importante.Various filling devices are known in which the air contained in the container is evacuated by a vent without this air being reintroduced into the liquid supply tank. However, known devices of this type involve losses of liquid to be drawn off which cannot be tolerated when the market value of the liquid to be drawn off is high.

Par ailleurs, ces dispositifs sont des dispositifs à commande mécanique avec des joints coulissants qui, outre des problèmes de réalisation mécanique, posent des problèmes importants de prolifération bacérienne.Furthermore, these devices are mechanical control devices with sliding seals which, in addition to problems of mechanical production, pose significant problems of bacterial proliferation.

La Demanderesse s'est donc posé le problème de réaliser un dispositif de remplissage de récipient par des liquides non gazeux qui soit à la fois simple à fabriquer, en diminuant le nombre de pièces nécessaires à sa réalisation, et aseptique, tout en ne diminuant pas la cadence de remplissage des récipients.The Applicant therefore posed the problem of producing a container filling device with non-gaseous liquids which is both simple to manufacture, reducing the number of parts necessary for its production, and aseptic, while not reducing the rate of filling of the containers.

Les caractéristiques et avantages ressortiront à la suite de la description qui va suivre faite en référence aux dessins annexés donnés uniquement à titre d'exemple non limitatif et parmi lesquels :

The characteristics and advantages will become apparent after the description which follows made with reference to the appended drawings given solely by way of nonlimiting example and among which:
  • - Fig. 1 is a general view of an installation comprising the filling device according to the invention.
  • - Fig. 2 is a sectional view of the filling device according to the invention.
  • - Fig. 3 is a variant of the filling device according to the invention.

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, 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 liquid supply tank B, a container C, made of plastic or other material, carried by a lifting device D.

Comme illustré Fig. 2, le dispositif de remplissage A est constitué d'un corps 1 d'axe X-X, d'une sonde électrique 2, coaxiale traversant le corps 1 sur toute sa hauteur, d'un manchon 3 d'axe X-X d'évacuation de l'air situé dans le récipient C à remplir, d'un conduit d'écoulement 4 du liquide, et d'une membrane 5, en élastomère ou autre matériau élastique. Selon une forme de réalisation préférentielle de l'invention, cette membrane 5 est constituée d'une rondelle circulaire d'axe X-X percée en son centre d'un orifice circulaire coaxial 0.As illustrated in Fig. 2, the filling device A consists of a body 1 of axis XX, an electrical probe 2, coaxial passing through the body 1 over its entire height, of a sleeve 3 of axis XX for discharging the air located in the container C to be filled, a liquid flow conduit 4, and a membrane 5, made of elastomer or other elastic material. According to a preferred embodiment of the invention, this membrane 5 consists of a circular washer of axis X-X pierced at its center with a coaxial circular orifice 0.

Le corps 1, d'axe vertical X-X, est percé, à sa face supérieure, d'un orifice supérieur coaxial 6, et à sa face inférieure, d'un orifice inférieur coaxial 7.The body 1, of vertical axis X-X, is pierced, on its upper face, with a coaxial upper orifice 6, and on its lower face, with a coaxial lower orifice 7.

Les orifices 6 et 7 débouchent dans une chambre centrale 8, d'axe X-X, du corps 1. Cette chambre 8 est limitée par un plafond constitué, d'une surface annulaire 9, raccordé avec une paroi verticale 10 par une surface de révolution 11 d'axe X-X qui constitue la périphérie de cette chambre centrale 8. Cette chambre 8 est limitée, inférieurement, par un plancher 12 relié à l'orifice inférieur 7 par un épaulement 13.The orifices 6 and 7 open into a central chamber 8, of axis XX, of the body 1. This chamber 8 is limited by a ceiling consisting of an annular surface 9, connected with a vertical wall 10 by a surface of revolution 11 of axis XX which constitutes the periphery of this central chamber 8. This chamber 8 is limited, below, by a floor 12 connected to the lower orifice 7 by a shoulder 13.

Cette chambre centrale 8 communique avec une chambre périphérique 14, d'axe X-X, par un passage annulaire entre une surface inférieure 15 de la paroi 10 et le plancher 12 qui se prolonge radialement au­delà de cette paroi 10.This central chamber 8 communicates with a peripheral chamber 14, of axis X-X, by an annular passage between a lower surface 15 of the wall 10 and the floor 12 which extends radially beyond this wall 10.

Cette chambre 14 est limitée, à son extrémité supérieure, par une surface annulaire 16. Dans l'exemple de réalisation représenté Fig. 2 cette surface 16 est de section courbe mais elle pourrait être de section droite. Cette surface 16 se raccorde, vers l'intérieur en direction de l'axe X-X, à une surface 17 de révolution d'axe X-X. Cette surface 17 constitue donc, avec les surfaces 15 et 11, la paroi 10.This chamber 14 is limited, at its upper end, by an annular surface 16. In the embodiment shown in FIG. 2 this surface 16 is of curved section but it could be of straight section. This surface 16 is connected, inwards in the direction of the axis XX, to a surface 17 of revolution of axis XX. This surface 17 therefore constitutes, with the surfaces 15 and 11, the wall 10.

La chambre annulaire 14 est limitée, à sa périphérie, par une surface 18 de révolution d'axe X-X qui se raccorde à la fois avec le plancher 12 et la surface annulaire 16 qui constitue le plafond de la chambre périphérique 14. Un conduit 19 débouche dans la chambre périphérique 14 reliant cette chambre périphérique 14 à la cuve B d'alimentation en liquide.The annular chamber 14 is limited, at its periphery, by a surface 18 of revolution of axis XX which is connected both with the floor 12 and the annular surface 16 which constitutes the ceiling of the peripheral chamber 14. A conduit 19 opens out in the peripheral chamber 14 connecting this peripheral chamber 14 to the liquid supply tank B.

Ainsi, le dispositif de remplissage A selon l'invention présente un corps 1 constitué d'une chambre centrale 8 d'axe vertical X-X communiquant avec une chambre périphérique 14 par un passage annulaire ménagé entre la paroi 10 de séparation des chambres centrale 8 et périphérique 14, formant la surface de siège 15, et une surface 12 (plancher 12) de la chambre centrale se prolongeant radialement au­delà de la paroi 10 dans la chambre périphérique 14.Thus, the filling device A according to the invention has a body 1 consisting of a central chamber 8 of vertical axis XX communicating with a peripheral chamber 14 by an annular passage formed between the wall 10 for separation of the central 8 and peripheral chambers 14, forming the seat surface 15, and a surface 12 (floor 12) of the central chamber extending radially beyond the wall 10 in the peripheral chamber 14.

A proximité du plancher 12, une gorge annulaire 20 est ménagée à la périphérie de la surface 18, entre l'arrivée du conduit 19 dans la chambre périphérique 14 et le plancher 12. Cette gorge annulaire 20 correspond à un plan de joint entre une partie supérieure 100 et une partie inférieure 101 du corps 1.Near the floor 12, an annular groove 20 is formed at the periphery of the surface 18, between the arrival of the conduit 19 in the peripheral chamber 14 and the floor 12. This annular groove 20 corresponds to a plane of joint between a part upper 100 and lower part 101 of the body 1.

Par ailleurs, un conduit 22 débouche dans la chambre périphé­rique 14, ou dans la chambre centrale 8, par le plancher 12. Ce conduit 22 est relié à une source de gaz sous pression non représentée par une électrovanne E.Furthermore, a conduit 22 opens into the peripheral chamber 14, or into the central chamber 8, through the floor 12. This conduit 22 is connected to a source of pressurized gas not represented by a solenoid valve E.

Le manchon 4, qui se prolonge à partir de l'épaulement 13 à travers l'orifice 7 en-dessous du dispositif A, permet par ailleurs de fixer le bord intérieur de la membrane 5 contre ledit épaulement, cette membrane 5 étant de plus fixée, par son bord périphérique, dans la gorge annulaire 20 de la surface de révolution 18.The sleeve 4, which extends from the shoulder 13 through the orifice 7 below the device A, also makes it possible to fix the inner edge of the membrane 5 against said shoulder, this membrane 5 being moreover fixed , by its peripheral edge, in the annular groove 20 of the surface of revolution 18.

La surface 15 de la paroi 10 se situe radialement approximativement à mi-distance entre l'épaulement 13 et la gorge annulaire 20. De plus, un écart de quelques millimètres est ménagé entre la surface supérieure de la membrane 5 et cette surface 15. Ainsi, comme illustré Fig. 2, la membrane 5, fixée à la chambre périphérique 14 et se prolongeant radialement vers l'axe X-X au-delà de la paroi 10, forme avec la surface 12 (plancher 12) une chambre annulaire 23 déformable.The surface 15 of the wall 10 is located radially approximately halfway between the shoulder 13 and the annular groove 20. In addition, a gap of a few millimeters is provided between the upper surface of the membrane 5 and this surface 15. Thus , as illustrated in Fig. 2, the membrane 5, fixed to the peripheral chamber 14 and extending radially towards the axis XX beyond the wall 10, forms with the surface 12 (floor 12) an annular chamber 23 deformable.

Enfin, le manchon 3, fixé au corps 1 de façon étanche au niveau de l'orifice 6, se prolonge vers le bas à travers le manchon 4 et débouche en-dessous de celui-ci. Ce manchon 3 est traversé sur toute sa hauteur par la sonde électrique 2.Finally, the sleeve 3, fixed to the body 1 in a leaktight manner at the orifice 6, extends downward through the sleeve 4 and opens out below the latter. This sleeve 3 is traversed over its entire height by the electrical probe 2.

Un conduit annulaire 42 est ménagé entre la sonde électrique 2 et la surface interne du manchon 3. Ce conduit annulaire 24, ouvert à son extrémité inférieure située au-dessous du manchon 4, débouche à l'air libre à son extrémité supérieure grâce à un orifice 25.An annular conduit 42 is formed between the electrical probe 2 and the internal surface of the sleeve 3. This annular conduit 24, open at its lower end situated below the sleeve 4, opens into the open air at its upper end thanks to a orifice 25.

Par ailleurs, le diamètre interne du manchon 4 étant supérieur au diamètre externe du manchon 3, un canal annulaire 26 relie la chambre centrale 8 avec l'extérieur du dispositif A.Furthermore, the internal diameter of the sleeve 4 being greater than the external diameter of the sleeve 3, an annular channel 26 connects the central chamber 8 with the exterior of the device A.

Enfin, un détecteur de proximité P du récipient C à remplir est placé, par exemple, sur le dispositif de remplissage A selon l'invention. Selon l'exemple de réalisation représenté Fig. 1, ce détecteur P est fixé au corps 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, for example, on the filling device A according to the invention. According to the embodiment shown in FIG. 1, this detector P is fixed to the body 1, but it could be independent of this body 1 and placed, for example, on the lifting device D.

VARIANTES :VARIANTS:

- la variante représentée figure 3 représente une adaptation du dispositif de remplissage selon l'invention à un dispositif de remplissage dit "à canule longue".- The variant shown in Figure 3 shows an adaptation of the filling device according to the invention to a filling device called "long cannula".

Dans cette variante, le manchon 3 et la sonde 2 ont été supprimés l'orifice 6 ayant aussi disparu. Le manchon 4 a de plus été remplacé par une canale longue 41 sur laquelle a été fixée à l'extérieur de celle-ci une sonde 42. Du fait de la présence de la sonde 42 à l'extérieur de la canule 41, cette dernière est avantageusement réalisée en matériau isolant.In this variant, the sleeve 3 and the probe 2 have been removed the orifice 6 having also disappeared. The sleeve 4 has moreover been replaced by a long channel 41 on which a probe 42 has been fixed on the outside thereof. Due to the presence of the probe 42 outside the cannula 41, the latter is advantageously made of insulating material.

- la variante représentée figure 4 représente une autre adaptation du dispositif de remplissage selon l'invention à un dispositif de remplissage à canule longue, dans lequel les parties 100 et 101 du corps 1 ont été inversées. Ainsi, l'orifice 7 a été supprimé et une canule longue 411 a été fixée à l'orifice 6 et munie d'une sonde 42. La membrane 5 n'est plus percée d'un orifice central 0.- The variant shown in Figure 4 shows another adaptation of the filling device according to the invention to a filling device with long cannula, in which the parts 100 and 101 of the body 1 have been reversed. Thus, the orifice 7 has been eliminated and a long cannula 411 has been fixed to the orifice 6 and provided with a probe 42. The membrane 5 is no longer pierced with a central orifice 0.

FONCTIONNEMENTOPERATION

Au repos, c'est-à-dire quand aucun récipient C n'est à remplir, de l'air sous pression, fourni par l'électrovanne E via le conduit 22 dans la chambre annulaire 23 plaque la membrane 5 contre la surface 15 de la paroi 10. Ainsi, le liquide à soutirer arrivant par le conduit 19 dans la chambre périphérique 14 ne peut s'écouler par la chambre centrale 8 et le conduit annulaire 26 dans le récipient C à remplir.At rest, that is to say when no container C is to be filled, pressurized air supplied by the solenoid valve E via the conduit 22 in the annular chamber 23 presses the membrane 5 against the surface 15 from the wall 10. Thus, the liquid to be withdrawn arriving via the conduit 19 in the peripheral chamber 14 cannot flow through the central chamber 8 and the annular conduit 26 into the container C to be filled.

Quand le dispositif de levage D monte le récipient C jusqu'à ce que le manchon 4 pénètre à l'intérieur du col du récipient C, le détecteur de proximité P est excité et commande alors l'électrovanne E qui fait diminuer la pression règnant dans la chambre annulaire 23. Ainsi, la membrane 5 n'étant plus en contact avec la surface 15 de la paroi 10, la chambre périphérique 14 est mise en communication avec la chambre centrale 8.When the lifting device D raises the container C until the sleeve 4 penetrates inside the neck of the container C, the proximity detector P is activated and then controls the solenoid valve E which reduces the pressure prevailing in the annular chamber 23. Thus, the membrane 5 no longer being in contact with the surface 15 of the wall 10, the peripheral chamber 14 is placed in communication with the central chamber 8.

Le liquide peut donc s'écouler dans le récipient C à remplir, par le conduit annulaire 26 constitué par la face interne du manchon 4 et la face externe du manchon 3.The liquid can therefore flow into the container C to be filled, through the annular conduit 26 constituted by the internal face of the sleeve 4 and the external face of the sleeve 3.

L'air contenu dans le récipient C peut s'échapper par le conduit annulaire 24 constitué par le manchon 3 et la sonde 2 à travers l'orifice 25. Ainsi l'air contenu dans le récipient à remplir n'est pas évacué dans la cuve d'alimentation en liquide sans pour autant que du liquide à soutirer soit perdu dans cette opération.The air contained in the container C can escape through the annular conduit 24 constituted by the sleeve 3 and the probe 2 through the orifice 25. Thus the air contained in the container to be filled is not evacuated in the liquid supply tank without losing any liquid to be drawn off in this operation.

Quand le liquide atteint le niveau de la sonde 2, celle-ci commande l'électrovanne E qui remet alors sous pression la chambre annulaire 23, ainsi la membrane 5 est de nouveau plaquée contre la surface 15 de la paroi 10 et le remplissage du récipient C est alors achevé, un nouveau cycle peut alors commencer.When the liquid reaches the level of the probe 2, the latter controls the solenoid valve E which then pressurizes the annular chamber 23, thus the membrane 5 is again pressed against the surface 15 of the wall 10 and the filling of the container. C is then completed, a new cycle can then begin.

Ainsi, grâce au dispositif de remplissage selon l'invention, le remplissage est effectué avec une grande hygiène, à la fois par le retour d'air séparé et par l'absence de pièces un mouvement, et donc de joints, qui sont autant de pièges à bactéries. Par ailleurs le lavage d'un dispositif de remplissage selon l'invention est très simplifié, puisqu'il suffit de couper l'alimentation en gaz sous pression de la chambre annulaire 23 pour ouvrir tout le dispositif de remplissage A et le mettre ainsi en position en lavage.Thus, thanks to the filling device according to the invention, filling is carried out with great hygiene, both by the separate air return and by the absence of moving parts, and therefore of seals, which are as many bacteria traps. Furthermore, the washing of a filling device according to the invention is very simplified, since it suffices to cut off the supply of pressurized gas to the annular chamber 23 to open the entire filling device A and thus put it in position. in washing.

En outre, le dispositif de remplissage n'entraîne aucune perte de liquide puisque, par son principe même, l'alimentation est arrêtée dès que la quantité de liquide nécessaire a été fournie.In addition, the filling device does not cause any loss of liquid since, by its very principle, the supply is stopped as soon as the necessary quantity of liquid has been supplied.

De plus, le dispositif de remplissage selon l'invention fonctionne parfaitement, même en l'absence de tout contact étanche entre le col du récipient C à remplir et le dispositif de remplissage A.In addition, the filling device according to the invention works perfectly, even in the absence of any sealed contact between the neck of the container C to be filled and the filling device A.

Enfin, il suffit d'introduire quelques centimètres cube d'air sous la membrane 5 dans la chambre annulaire 23 pour passer de la position d'ouverture à la position de fermeture de dispositif de remplissage A.Finally, it suffices to introduce a few cubic centimeters of air under the membrane 5 into the annular chamber 23 to pass from the open position to the closed position of filling device A.

Ainsi, le dispositif de remplissage selon l'invention présente des temps de fermeture de l'ordre de 20 millisecondes, alors qu'il est habituellement considéré que les disposifits pneumatiques sont lents.Thus, the filling device according to the invention has closing times of the order of 20 milliseconds, while it is usually considered that the pneumatic devices are slow.
