Abstract

The bottle filler consists of a nozzle (120) connected to a container (110) of the liquid (112) and containing an air return tube lying coaxially with its cannula (126) inside the nozzle and having a radial aperture (125) adjacent to the nozzle tip. The outlet end of the cannula is situated at one height (Ho), while the aperture (125) in the air return tube (124) is situated at a second height (H1) above it. Both the cannula and air return tube are at atmospheric pressure.

Description

La présente invention concerne un dispositif d'emplissage de bouteilles avec un liquide et de mise à niveau de ce liquide dans ces bouteilles, sans perte de liquide.The present invention relates to a device for filling bottles with a liquid and leveling that liquid in these bottles without loss of fluid.

On connaít un bec d'emplissage tel que celui représenté à titre indicatif sur la figure 1. Ce bec de l'art antérieur (voir FR-A-2 466 433) comprend de façon simplifiée une cuve 10 dans laquelle est conservé le liquide 12 dont on doit emplir la bouteille 14.We know a filling spout such as that shown for information in FIG. 1. This spout of the prior art (see FR-A-2 466 433) includes in a simplified manner a tank 10 in which the liquid 12 is stored with which the bottle 14.

La bouteille 14 est amenée sous le bec pour son emplissage. On note que dans ce type de bec de l'art antérieur, le bec est fixe et la bouteille est mobile en translation verticale pour provoquer l'emplissage comme cela va être expliqué ultérieurement.The bottle 14 is brought under the spout for its filling. We notice that in this type of spout of the prior art, the spout is fixed and the bottle is mobile in vertical translation to cause filling as it is going to be explained later.

Ainsi que montré sur la figure 1 des dessins annexés, le bec comprend une canule 16 de retour d'air et de guidage, fixe en translation avec un embout 18 et son extrémité 19, rapporté à l'extrémité inférieure de cette canule, un corps 20 de bec, coaxial à la canule et mobile entre deux positions par rapport à ladite canule, une première position dans laquelle ce corps coopère de façon étanche avec l'embout 18, interdisant tout écoulement et une seconde position dans laquelle ce corps est soulevé par rapport à l'embout 18, laissant s'écouler le liquide.As shown in Figure 1 of the accompanying drawings, the spout comprises a cannula 16 for air return and guide, fixed in translation with a end piece 18 and its end 19, attached to the lower end of this cannula, a nozzle body 20, coaxial with the cannula and movable between two positions relative to said cannula, a first position in which this body cooperates tightly with the nozzle 18, preventing any flow and a second position in which this body is raised relative to the nozzle 18, letting the liquid flow.

De plus, des moyens 22 de liaison souple avec rappel élastique, sont interposés entre la cuve et le corps de bec, en l'occurrence, une membrane en élastomère. Ces moyens de liaison ont une double fonction, la première de permettre une continuité de l'écoulement entre la cuve et la bouteille et la seconde de rappeler le corps de bec pour que son extrémité soit plaquée de façon étanche contre l'embout 18 en dehors des phases d'emplissage.In addition, flexible connection means 22 with elastic return are interposed between the tank and the spout body, in this case, a membrane in elastomer. These connecting means have a double function, the first of allow continuity of flow between the tank and the bottle and the second to recall the spout body so that its end is pressed sealingly against the nozzle 18 outside the filling phases.

Le bec de l'art antérieur comprend de plus un tube 24 de retour d'air qui permet de supprimer le côté aléatoire de la mise à niveau à la fin de l'emplissage. Ce tube de retour d'air débouche par une ouverture 25 ménagée dans la paroi du corps 20 de bec.The spout of the prior art further comprises an air return tube 24 which allows you to remove the random side of the upgrade at the end of filling. This return air tube opens out through an opening 25 in the wall of the spout body 20.

Ce tube présente un inconvénient industriel, c'est qu'il doit être logé entre la canule et le corps de bec, dans un espace relativement étroit. Sa fabrication et sa mise en place sont assez délicates. On note aussi qu'il peut se produire des frottements entre la canule 16 et le tube 24 de retour d'air car les jeux de fonctionnement sont très faibles comme on l'a expliqué ci-avant.This tube has an industrial drawback, it must be housed between the cannula and the nozzle body, in a relatively narrow space. Her manufacturing and its implementation are quite delicate. We also note that it can friction occurs between the cannula 16 and the air return tube 24 because the operating clearances are very small as explained above.

Durant le fonctionnement, il se pose aussi un problème fonctionnel de mise à niveau.During operation, there is also a functional problem of Upgrade.

En effet, notamment dans le domaine de l'eau minérale, des quantités très importantes de bouteilles sont emplies et la mise à niveau pose un problème car elle engendre des pertes d'eau.Indeed, especially in the field of mineral water, quantities very large bottles are filled and the upgrade poses a problem because it causes water loss.

En effet, lorsque l'emplissage s'effectue, la bouteille est soulevée jusqu'à ce que son goulot 26 vienne en appui de façon étanche contre une collerette 28, solidaire du corps 20 du bec.When the filling takes place, the bottle is lifted until its neck 26 comes to bear sealingly against a flange 28, integral with the body 20 of the spout.

Le soulèvement de cette collerette et donc du corps de bec provoque l'écoulement gravitaire du liquide contenu dans la cuve jusque dans la bouteille, jusqu'à ce que le niveau soit tel que ce liquide obstrue la sortie 25 du tube 24 de retour d'air. Dès lors, le liquide se situe à un niveau H1, haut.The lifting of this flange and therefore of the spout body causes the gravity flow of the liquid contained in the tank to the bottle, until the level is such that this liquid obstructs the outlet 25 of the tube 24 for return of air. Therefore, the liquid is located at a level H 1 , high.

La bouteille est redescendue pour permettre aux moyens de liaison et de rappel de venir arrêter l'écoulement et au goulot 26 de la bouteille de se décoller de la collerette 28. L'orifice 25 n'est plus obstrué.The bottle is lowered to allow the connecting means and reminder to stop the flow and at the neck 26 of the bottle take off from the collar 28. The orifice 25 is no longer obstructed.

Une légère dépression est généralement maintenue au-dessus du niveau du liquide dans la cuve et la canule débouche dans ce ciel en légère dépression. Ceci permet donc d'exercer cette légère dépression dans la bouteille, à travers la canule, ce qui a pour effet d'aspirer le liquide à travers la canule 16, le liquide aspiré s'écoulant alors dans la cuve à la sortie de l'extrémité haute de ladite canule. Cette aspiration se prolonge jusqu'à ce que le niveau du liquide se situe en H0, c'est à dire au droit de l'extrémité inférieure de la canule. De ce fait, le niveau du liquide est identique pour toutes les bouteilles puisque l'embout 18 est fixe.A slight depression is generally maintained above the level of the liquid in the tank and the cannula opens into this sky in slight depression. This therefore makes it possible to exert this slight depression in the bottle, through the cannula, which has the effect of sucking the liquid through the cannula 16, the sucked liquid then flowing in the tank at the outlet of the upper end of said cannula. This aspiration continues until the level of the liquid is at H 0 , that is to say at the level of the lower end of the cannula. Therefore, the level of the liquid is identical for all the bottles since the nozzle 18 is fixed.

On note que, dans cet agencement, le liquide aspiré a été au contact de l'air ambiant et que de l'air ambiant est aussi aspiré par les tubes de retour d'air à la fin de l'opération de mise à niveau dite d'égalisation.It is noted that, in this arrangement, the liquid sucked has been in contact with ambient air and that ambient air is also drawn in through the return tubes air at the end of the so-called equalization leveling operation.

Ceci est sans conséquence pour certains liquides mais pose des problèmes notamment dans le cas de l'eau minérale car il est souhaitable ni de mélanger l'eau aspirée d'une bouteille ni de mettre l'air ambiant en contact avec l'eau contenue dans la cuve et issue de l'alimentation d'eau, afin d'éviter les problèmes de contamination.This is of no consequence for certain liquids but poses problems especially in the case of mineral water because it is desirable neither to mix the water drawn from a bottle or bring the ambient air into contact with the water contained in the tank and from the water supply, in order to avoid contamination issues.

La solution consiste à l'heure actuelle à aspirer l'eau par dépression et à la rejeter, ce qui occasionne des pertes d'eau importantes, alors que l'on se doit de gérer au plus juste les quantités utilisées.The solution currently consists of vacuuming the water and reject it, which causes significant water losses, while must manage the quantities used as accurately as possible.

Le dispositif selon l'invention permet un emplissage de bouteilles, notamment avec de l'eau minérale, qui évite toute perte d'eau, qui permet de conserver les mises à niveau identiques pour toutes les bouteilles, notamment lorsque ce dispositif est monté sur des carrousels de machines à hautes cadences, qui permet de s'affranchir du montage délicat du tube de retour d'air entre le corps du bec et la canule, qui est de plus adaptable sur les machines existantes et qui permet d'éviter les mélanges et/ou les contacts air/eau évoqués ci-dessus.The device according to the invention allows filling of bottles, especially with mineral water, which prevents any loss of water, which allows keep the same upgrades for all bottles, especially when this device is mounted on carousels of tall machines rates, which eliminates the delicate assembly of the return tube air between the body of the spout and the cannula, which is more adaptable on the existing machines and which avoids mixing and / or contact air / water mentioned above.

A cet effet, selon l'invention, le dispositif d'emplissage de bouteilles du type comprenant un bec d'emplissage relié à une cuve contenant un liquide à embouteiller par des moyens de liaison, ce bec comprenant une canule de retour d'air avec un embout fixe en translation par rapport à un corps de bec mobile en translation entre une première position dans laquelle le liquide peut s'écouler entre ledit corps de bec et l'embout, et une seconde position dans laquelle ledit corps de bec est en contact étanche avec l'embout, caractérisé en ce qu'il comprend un tube de retour d'air qui est coaxial à la canule et intérieur au corps de bec et qui débouche par au moins une ouverture radiale, sensiblement au droit de l'embout et à hauteur du bout du tube du corps de bec.To this end, according to the invention, the device for filling bottles of the type comprising a filling spout connected to a tank containing a liquid bottle by connecting means, this spout comprising an air return cannula with a tip fixed in translation relative to a spout body movable in translation between a first position in which the liquid can flow between said nozzle body and end piece, and a second position in which said body spout is in tight contact with the nozzle, characterized in that it comprises a return air tube which is coaxial with the cannula and inside the nozzle body and which opens through at least one radial opening, substantially at the right of the nozzle and up to the end of the tube of the nozzle body.

Selon une autre caractéristique, la canule de retour d'air et de guidage débouche à une hauteur H0 et l'ouverture du tube de retour d'air libre débouche à une hauteur H1 située au-dessus de celle de la canule.According to another characteristic, the air return and guide cannula opens at a height H 0 and the opening of the free air return tube opens at a height H 1 located above that of the cannula.

Quant à l'ouverture du tube de retour d'air, elle débouche sensiblement radialement et celle de la canule débouche verticalement par une ouverture et constitue le point bas H0 de l'embout et du bec.As for the opening of the air return tube, it opens substantially radially and that of the cannula opens vertically through an opening and constitutes the low point H 0 of the nozzle and the spout.

Selon un mode de réalisation préférentiel, la canule et le tube de retour d'air sont à la pression atmosphérique.According to a preferred embodiment, the cannula and the return tube of air are at atmospheric pressure.

L'invention est maintenant décrite en regard des dessins annexés sur lesquels les différentes figures représentent :

  • figure 1, une vue de l'art antérieur préalablement décrit,
  • figure 2A, une vue d'un mode de réalisation non limitatif d'un bec d'emplissage selon l'invention lors de la première phase d'un synoptique de fonctionnement du dispositif d'emplissage selon la présente invention, et
  • Figures 2B à 2F, les étapes suivantes du synoptique de fonctionnement du dispositif d'emplissage selon la présente invention.
The invention is now described with reference to the appended drawings in which the various figures represent:
  • FIG. 1, a view of the prior art previously described,
  • FIG. 2A, a view of a nonlimiting embodiment of a filling spout according to the invention during the first phase of a block diagram of the filling device according to the present invention, and
  • Figures 2B to 2F, the following steps of the block diagram of the filling device according to the present invention.

Sur la figure 2A, on a représenté un bec dont les parties identiques ou pour le moins qui jouent le même rôle, portent les mêmes références que celles de la figure 1 mais augmentées de 100.In FIG. 2A, a beak is shown, the identical or at least who play the same role, have the same references as those in Figure 1 but increased by 100.

Une cuve est référencée 110.A tank is referenced 110.

Le tube 124 de retour d'air est par contre agencé différemment.The air return tube 124 is on the other hand arranged differently.

En effet, ce tube 124 de retour d'air est monté coaxial extérieur à la canule 116, également fixe en translation comme ladite canule et intérieur au corps 120 de bec. L'extrémité 130 inférieure de ce tube 124 de retour d'air débouche latéralement par trois ouvertures 125, dans l'embout 118, au-dessus de l'extrémité inférieure 119 de la canule. L'extrémité supérieure de ce tube 124 débouche à l'air libre, de façon connue. In fact, this air return tube 124 is mounted coaxial outside the cannula 116, also fixed in translation like said cannula and inside the spout body 120. The lower end 130 of this air return tube 124 opens laterally through three openings 125, in the nozzle 118, above from the lower end 119 of the cannula. The upper end of this tube 124 opens into the open air, in a known manner.

On remarque le corps 120 de bec qui vient obturer de façon étanche l'ouverture 125 du tube 124 de retour d'air, en position basse.We notice the body 120 of spout which seals tightly the opening 125 of the air return tube 124, in the low position.

Sur la figure 2A, l'extrémité 119 de la canule 116 est en position H0.In FIG. 2A, the end 119 of the cannula 116 is in position H 0 .

L'extrémité du goulot 126 peut prendre au moins trois positions : H2 d'attente, H3 de contact et H4 d'emplissage.The end of the neck 126 can take at least three positions: H 2 waiting, H 3 contact and H 4 filling.

Dans le cas de la phase représentée sur la figure 2A, le goulot de la bouteille est en position H2 d'attente, le bec est fermé car le corps 120 du bec est en position basse et vient en contact étanche avec l'embout 118. De même, on constate que l'ouverture 125 du tube 124 de retour d'air est obturée.In the case of the phase shown in FIG. 2A, the neck of the bottle is in the standby position H 2 , the spout is closed because the body 120 of the spout is in the low position and comes into tight contact with the nozzle 118 Likewise, it can be seen that the opening 125 of the air return tube 124 is closed.

Au cours de la phase de la figure 2B, la bouteille 114 a son goulot 126 qui est amené au niveau H4, après être venue en contact avec la collerette 128 en H3, ce qui provoque le soulèvement du corps 120 du bec et l'écoulement du contenu de la cuve à l'intérieur de la bouteille, pour autant que la cuve soit emplie.During the phase of FIG. 2B, the bottle 114 has its neck 126 which is brought to level H 4 , after having come into contact with the flange 128 in H 3 , which causes the body 120 to be raised from the spout and the flow of the contents of the tank inside the bottle, provided that the tank is filled.

Le goulot 126 étant en contact étanche avec la collerette 128, les ouvertures 116 et 125 de retour d'air assurent l'évacuation de l'air contenu dans la bouteille, permettant ainsi un emplissage gravitaire, sans aucun frein à l'écoulement.The neck 126 being in leaktight contact with the collar 128, the air return openings 116 and 125 ensure the evacuation of the air contained in the bottle, allowing gravity filling, without any brake the flow.

Lorsque l'emplissage en liquide est tel que ce liquide atteint sensiblement le niveau H1, le liquide reste à niveau constant dans la bouteille et monte dans le tube 124 de retour d'air et dans la canule 116 de retour d'air puis l'écoulement s'arrête par équilibre des pressions. C'est la position de la figure 2C.When the liquid filling is such that this liquid reaches substantially the level H 1 , the liquid remains at constant level in the bottle and rises in the air return tube 124 and in the air return cannula 116 then l flow stops by balancing pressures. This is the position of Figure 2C.

Sur la figure 2D, l'écoulement de la cuve est arrêté par abaissement du goulot 126 au niveau H3, ce qui ramène le corps 120 de bec dans sa position de fermeture étanche en obturant aussi l'ouverture 125 et en interdisant tout écoulement du liquide contenu dans le tube 124 de retour d'air.In FIG. 2D, the flow of the tank is stopped by lowering the neck 126 to level H 3 , which brings the body 120 of the spout back into its sealed closing position by also closing the opening 125 and preventing any flow of the liquid contained in the air return tube 124.

Dans ce cas, il est à noter que le phénomène de formation de bulles susceptibles de remonter dans l'espace annulaire défini par le corps 120 de bec à l'extérieur et le tube 124 de retour d'air à l'intérieur, à travers le fluide en écoulement, est impossible. Ceci est une sécurité quant à la pollution de la cuve par de l'air ayant été en contact avec une bouteille.In this case, it should be noted that the phenomenon of bubble formation likely to go up in the annular space defined by the body 120 of nozzle on the outside and the air return tube 124 on the inside, through the fluid in flow, is impossible. This is security for the pollution of the tank by air having been in contact with a bottle.

Cette position, avec le goulot 126 toujours en contact avec la collerette 128, interdit aussi tout écoulement du liquide contenu dans la canule 116. 6.This position, with the neck 126 still in contact with the flange 128, also prohibits any flow of the liquid contained in the cannula 116. 6.

Sur la figure 2E, dès que le goulot 126 est décollé de la collerette 128, le liquide contenu dans la canule 116 s'écoule par gravité dans la bouteille tandis que le liquide contenu dans le tube 124 de retour d'air est toujours retenu dans ce tube. La mise à niveau, donc le réglage du niveau, doit tenir compte de ce reliquat de liquide contenu dans la canule 116 pour atteindre le niveau final HF souhaité dans la bouteille en fin d'emplissage. Ce niveau HF est obtenu par la position en hauteur de la collerette 128 sur le corps 120 du bec.In FIG. 2E, as soon as the neck 126 is detached from the flange 128, the liquid contained in the cannula 116 flows by gravity into the bottle while the liquid contained in the air return tube 124 is always retained in this tube. The leveling, therefore the level adjustment, must take account of this residual liquid contained in the cannula 116 to reach the final level H F desired in the bottle at the end of filling. This level H F is obtained by the height position of the flange 128 on the body 120 of the spout.

Sur la figure 2F, on constate que la bouteille emplie peut être ramenée à sa position H2 prête à être bouchée par la suite par tout moyen adapté. On note que le tube 124 de retour d'air contient toujours le liquide qui s'écoule dans la bouteille suivante traitée par le même bec dès le début du remplissage, ce qui ne perturbe pas la mise à niveau dans la bouteille suivante.In FIG. 2F, it can be seen that the filled bottle can be brought back to its position H 2 ready to be capped thereafter by any suitable means. It is noted that the air return tube 124 always contains the liquid which flows in the next bottle treated by the same spout from the start of filling, which does not disturb the leveling in the next bottle.

Le dispositif selon la présente invention présente un avantage certain quant à la fabrication industrielle car le montage de tubes coaxiaux avec une sortie radiale est relativement simple et de plus la mise à l'air libre est réalisée au moyen d'une section supérieure à celle du petit tube de l'art antérieur ce qui favorise l'écoulement et évite toute mise en torche du bec.The device according to the present invention has a certain advantage as for industrial manufacturing because the mounting of coaxial tubes with a radial outlet is relatively simple and moreover the venting is carried out by means of a section greater than that of the small tube of the prior art, this which promotes flow and avoids any torch spout.

Les problèmes de gouttage du tube de retour d'air de l'art antérieur, notamment du fait de sa faible section et des phénomènes de capillarité sont également résolus simultanément puisque d'une part la section est augmentée et que d'autre part l'ouverture est obturée pendant les phases intermédiaires.The problems of dripping from the air return tube of the prior art, in particular because of its small section and capillarity phenomena are also solved simultaneously since on the one hand the section is increased and that on the other hand the opening is closed during the intermediate phases.

On note que l'emplissage s'effectue bien sans perte d'eau, par simple gravité.Note that the filling is done well without loss of water, by simple gravity.

Le dispositif qui vient d'être décrit peut être mis en service de façon identique dans un système d'emplissage ayant recours à un système de pression/dépression en atmosphère contrôlée pour la mise à niveau. The device which has just been described can be put into service so identical in a filling system using a filling system pressure / vacuum in controlled atmosphere for leveling.

La vitesse de remplissage peut être réglée par les variations de hauteur de charge ou par les variations de la pression/dépression dans le cas où l'agencement y a recours ou par réglage combiné de ces divers paramètres.The filling speed can be adjusted by height variations load or by variations in pressure / vacuum in the event that the layout uses them or by combined adjustment of these various parameters.
