Description

Bec de remplissage à niveau constant et carrousel de remplissage le comportant  Constant level filling spout and filling carousel with it
La présente invention concerne un bec de remplissage à niveau constant et un carrousel de remplissage le comportant .  The present invention relates to a constant level filling spout and a filling carousel comprising it.
ARRIERE-PLAN DE L'INVENTION  BACKGROUND OF THE INVENTION
On connaît des carrousels de remplissage comportant une plate-forme tournante portant une série de becs de remplissage à niveau constant comprenant chacun un corps de bec comportant :  Filling carousels are known comprising a rotating platform carrying a series of constant level filling spouts each comprising a spout body comprising:
une partie de liaison annulaire configurée pour réaliser un appui étanche avec le col des récipients et délimitant une zone de distribution,  an annular connection portion configured to provide a sealing support with the neck of the containers and delimiting a dispensing zone,
un conduit de distribution relié à une source d'alimentation en liquide par l'intermédiaire d'un clapet de distribution et débouchant dans la zone de distribution, un évent d'échappement relié à un orifice d'échappement par l'intermédiaire d'un clapet d'échappement et débouchant dans la zone de distribution.  a distribution duct connected to a liquid supply source via a distribution valve and opening into the distribution zone, an exhaust vent connected to an exhaust port via a exhaust valve and opening into the distribution area.
Dans les becs de remplissage existants 1 ' évent d'échappement est formé par une canule débouchant au centre de la zone de distribution tandis que le conduit de distribution débouche selon une fente annulaire périphérique .  In the existing filler nozzles 1 'exhaust vent is formed by a cannula opening in the center of the dispensing area while the distribution conduit opens in a peripheral annular slot.
Le frottement du liquide sur les parois de la fente annulaire réduit la section effective de passage du liquide de sorte que les becs de remplissage à niveau constant actuels ont un débit faible comparativement aux autres becs de remplissage tels que les becs de remplissage pondéral.  The friction of the liquid on the walls of the annular gap reduces the effective cross-sectional area of the liquid so that the current constant-level fillers have a low flow rate compared to other fillers such as the fillers.
OBJET DE L'INVENTION  OBJECT OF THE INVENTION
Un but de l'invention est de proposer un bec de remplissage à niveau constant ayant un débit amélioré.  An object of the invention is to provide a constant level filling spout having an improved flow rate.
BREVE DESCRIPTION DE L'INVENTION  BRIEF DESCRIPTION OF THE INVENTION
En vue de la réalisation de ce but on propose selon l'invention un bec de remplissage à niveau constant dans lequel le conduit de distribution débouche au centre de la zone de distribution tandis que 1 ' évent d'échappement débouche à la périphérie de celle-ci. With a view to achieving this object, it is proposed according to the invention a constant-level filling spout in which the distribution conduit opens in the center of the dispensing zone while the exhaust vent opens at the periphery thereof.
Ainsi le liquide s'écoule selon un jet cylindrique présentant un débit maximum par rapport à la section de passage .  Thus the liquid flows in a cylindrical jet having a maximum flow with respect to the passage section.
Selon une version avantageuse de l'invention, 1 ' évent d'échappement débouche latéralement dans une fente annulaire s 'étendant en périphérie de la zone de distribution. On obtient ainsi une section de passage suffisante de l'échappement tout en minimisant la largeur de la fente annulaire.  According to an advantageous version of the invention, the exhaust vent opens laterally into an annular slot extending on the periphery of the distribution zone. This provides a sufficient passage section of the exhaust while minimizing the width of the annular slot.
Selon un mode de réalisation préféré de l'invention, le conduit de distribution délimite un côté de la fente annulaire. On minimise ainsi l'espace perdu dans la zone de distribution de sorte que le conduit de distribution peut avoir une section optimale.  According to a preferred embodiment of the invention, the distribution duct delimits one side of the annular slot. This minimizes the space lost in the distribution area so that the distribution duct can have an optimum section.
Selon un autre aspect avantageux de l'invention le clapet d'échappement est déporté latéralement par rapport au conduit de distribution. De préférence dans ce cas pour un carrousel de remplissage comportant une plate-forme tournante portant une série de becs de remplissage, le clapet d'échappement de chaque bec de remplissage est disposé radialement vers l'intérieur par rapport au conduit de distribution. On minimise ainsi l'encombrement de chaque bec de remplissage à la périphérie de la plate-forme tournante de sorte qu'un nombre optimal de becs de remplissage peut être implanté sur une plate-forme tournante de dimensions données.  According to another advantageous aspect of the invention, the exhaust valve is offset laterally with respect to the distribution duct. Preferably in this case for a filling carousel comprising a rotating platform carrying a series of filling spouts, the exhaust valve of each filling spout is arranged radially inwardly with respect to the distribution duct. This minimizes the size of each filling spout at the periphery of the rotating platform so that an optimal number of filling spouts can be implanted on a rotating platform of given dimensions.
Par ailleurs, les becs de remplissage antérieurs comportent généralement un clapet de distribution dont l'ouverture est commandée par la mise en appui de la partie de liaison sur un récipient. Lors de la fermeture du clapet de distribution, du liquide s'écoule dans le récipient selon une quantité qui varie en fonction de la vitesse de fermeture du clapet de distribution. La précision du niveau à l'intérieur d'un récipient s'en trouve donc affectée. Moreover, the prior filling spouts generally comprise a dispensing valve whose opening is controlled by the support of the connecting portion on a container. When closing the dispensing valve, liquid flows into the container in a quantity that varies according to the speed of the dispenser. closing of the distribution valve. The accuracy of the level inside a container is thus affected.
Selon un autre aspect avantageux de l'invention, le clapet de distribution est commandé indépendamment d'une présence d'un récipient. Ainsi le clapet de distribution peut être fermé avant de retirer le récipient de sorte que le niveau du liquide dans le récipient n'est pas affecté par la manœuvre de retrait du récipient.  According to another advantageous aspect of the invention, the dispensing valve is controlled independently of the presence of a container. Thus the dispensing valve can be closed before removing the container so that the level of the liquid in the container is not affected by the withdrawal maneuver of the container.
En outre, les becs de remplissage de l'art antérieur comportent généralement des clapets commandés pour vider 1 ' évent d' échappement .  In addition, the filling nozzles of the prior art generally comprise valves controlled to empty the exhaust vent.
Selon encore un autre aspect de l'invention, le clapet d'échappement comporte une enceinte reliée à l' évent d'échappement et ayant une paroi comportant l'orifice d'échappement, et un corps flottant disposé dans l'enceinte en regard de l'orifice d'échappement, le corps flottant comprenant de préférence une bille disposée dans l'enceinte entre l'orifice d'échappement et un flotteur avantageusement en forme de cloche.  According to yet another aspect of the invention, the exhaust valve comprises an enclosure connected to the exhaust vent and having a wall comprising the exhaust port, and a floating body disposed in the enclosure opposite the exhaust port, the floating body preferably comprising a ball disposed in the chamber between the exhaust port and a preferably bell-shaped float.
Ainsi, une hausse du niveau de liquide dans l'enceinte provoque un déplacement du corps flottant jusqu'à l'obturation de l'orifice d'échappement. A l'inverse, une baisse du niveau de liquide dans l'enceinte provoque un l'ouverture de l'orifice d'échappement.  Thus, an increase in the level of liquid in the enclosure causes a displacement of the floating body until the closure of the exhaust port. Conversely, a drop in the liquid level in the enclosure causes an opening of the exhaust port.

DESCRIPTION DETAILLEE DE L'INVENTION  DETAILED DESCRIPTION OF THE INVENTION
En référence aux figures, le bec de remplissage selon l'invention comporte un corps de bec 1 traversé par un alésage vertical 2 comportant à sa partie inférieure un décrochement 3 dont le bord inférieur 4 forme une partie de liaison annulaire configurée pour réaliser un appui étanche avec un col de récipient 5 et délimitant une zone de distribution 6.  Referring to the figures, the filling spout according to the invention comprises a spout body 1 traversed by a vertical bore 2 having at its lower part a recess 3, the lower edge 4 of which forms an annular connection portion configured to produce a tight support. with a container neck 5 and delimiting a distribution zone 6.
Un conduit de distribution formé par un tube rectiligne 7 est monté dans l'alésage 2 et débouche au centre de la zone de distribution 6. Le tube de distribution 7 s'étend au-delà de la partie de liaison 4 sur une hauteur qui est fonction du niveau recherché dans le récipient ainsi qu'il sera vu plus loin. Le tube de distribution 7 est maintenu en place dans l'alésage 2 par un joint torique 8 comprimé par une douille vissée 9.  A distribution duct formed by a rectilinear tube 7 is mounted in the bore 2 and opens out at the center of the distribution zone 6. The distribution tube 7 extends beyond the connecting portion 4 to a height which is function of the desired level in the container as will be seen later. The distribution tube 7 is held in place in the bore 2 by an O-ring 8 compressed by a screwed socket 9.
À sa partie supérieure le tube de distribution 7 comporte un évasement 10 qui sert de siège pour un clapet 11. À son extrémité supérieure le tube de distribution 7 débouche dans le fond 15 d'une cuve d'alimentation 16 formant une plate-forme pivotante d'un carrousel de remplissage sur lequel les becs de remplissage sont montés.  At its upper part the distribution tube 7 has a flare 10 which serves as a seat for a valve 11. At its upper end the distribution tube 7 opens into the bottom 15 of a feed tank 16 forming a pivoting platform a filling carousel on which the filling spouts are mounted.
Une tige de commande 12 est fixée au clapet de distribution 11 et traverse la cuve d'alimentation 16. La tige de commande 12 est guidée au voisinage de son extrémité supérieure par une douille 28 (voir figure 2) fixée au couvercle 29 de la cuve d'alimentation 16. À son extrémité supérieure, la tige de commande 12 comporte un galet de commande 13 qui coopère avec une came 14 portée par le bâti (non représenté) du carrousel de remplissage. La position du clapet de distribution 11 est ainsi commandée de façon indépendante de la présence d'un récipient. À la partie inférieure de l'alésage 2 celui-ci comporte un décrochement 17 qui délimite avec le conduit de distribution 7 une fente annulaire 18 qui débouche à la périphérie de la zone de distribution 6. La fente annulaire 18 est associée à un évent d'échappement 19 relié à un orifice d'échappement 20 par l'intermédiaire d'un clapet d'échappement. Dans le mode de réalisation illustré, le clapet d'échappement est une bille creuse 21 supportée par un flotteur en forme de cloche 22 monté dans une enceinte 23 délimitée par un alésage 24 du corps de bec 1 dans lequel débouche l' évent d'échappement 19, et par un capot 25 qui comporte l'orifice d'échappement 20 et est fixé de façon étanche au corps de bec 1 par un joint torique 26 maintenu comprimé par des vis 27. La bille 21 et le flotteur 22 forment un corps flottant. A control rod 12 is fixed to the dispensing valve 11 and passes through the feed tank 16. The control rod 12 is guided near its upper end by a bushing 28 (see FIG. 2) attached to the lid 29 of the tank 16. At its upper end, the control rod 12 comprises a control roller 13 which cooperates with a cam 14 carried by the frame (not shown) of the filling carousel. The position of the dispensing valve 11 is thus controlled independently of the presence of a container. At the lower part of the bore 2, the latter comprises a recess 17 which delimits, with the distribution duct 7, an annular slot 18 which opens out at the periphery of the distribution zone 6. The annular slot 18 is associated with a ventilation port. exhaust 19 connected to an exhaust port 20 via an exhaust valve. In the illustrated embodiment, the exhaust valve is a hollow ball 21 supported by a bell-shaped float 22 mounted in an enclosure 23 delimited by a bore 24 of the nozzle body 1 into which the exhaust vent opens. 19, and by a cover 25 which has the exhaust port 20 and is sealingly attached to the spout body 1 by an O-ring 26 held compressed by screws 27. The ball 21 and the float 22 form a floating body .
Le fonctionnement du bec de remplissage selon l'invention est le suivant : le clapet de distribution 11 étant fermé, un récipient est mis en place avec le col 5 en appui contre la partie de liaison 4. Lors de la rotation de la plate-forme, le galet de commande 13 atteint la came 14 et ouvre le clapet de distribution 11. Lorsque le récipient est plein le liquide continue à s'écouler en passant par la fente annulaire 18 et par le conduit d'échappement 19 jusqu'à ce que le liquide dans l'enceinte 23 atteigne un niveau suffisant pour soulever le flotteur 22 et maintenir la bille 21 en appui contre l'orifice d'échappement. Le clapet de distribution 11 est ensuite fermé et le récipient est dégagé de l'appui contre la partie de liaison 4. Dans ce mouvement la partie de tube de distribution 7 engagée dans un récipient libère le volume correspondant tandis que le liquide contenu dans l' évent d'échappement s'écoule par gravité dans le récipient. On notera à ce propos que pour un liquide donné la quantité de liquide qui remonte dans l'enceinte 23 pour assurer la fermeture de l'orifice d'échappement 20 est constante quelle que soit la hauteur de pénétration du tube de distribution 7 dans le récipient. Pour obtenir le niveau souhaité dans le récipient il suffit donc de régler la hauteur de pénétration du tube de distribution 7 dans le récipient. The operation of the filling spout according to the invention is as follows: the dispensing valve 11 being closed, a container is put in place with the neck 5 bearing against the connecting part 4. During the rotation of the platform , the control roller 13 reaches the cam 14 and opens the dispensing valve 11. When the container is full the liquid continues to flow through the annular slot 18 and the exhaust pipe 19 until the liquid in the chamber 23 reaches a level sufficient to lift the float 22 and keep the ball 21 bearing against the exhaust port. The distribution valve 11 is then closed and the container is released from the support against the connecting portion 4. In this movement the distribution tube portion 7 engaged in a container releases the corresponding volume while the liquid contained in the exhaust vent flows by gravity into the container. Note in this connection that for a given liquid the amount of liquid that rises in the chamber 23 to ensure the closure of the exhaust port 20 is constant regardless of the height penetration of the dispensing tube 7 into the container. To obtain the desired level in the container it is sufficient to adjust the penetration height of the dispensing tube 7 in the container.
On notera également que la bille 21 n'est pas reliée à un actionneur externe : l'obturation et le dégagement de l'orifice d'échappement ne sont que le résultat de la variation du niveau de liquide dans l'enceinte 23. Les opérations de purge sont donc déclenchées par le seul retrait du récipient et sont réalisées indépendamment de toute commande extérieure ou d' actionneurs commandés.  Note also that the ball 21 is not connected to an external actuator: the closure and the release of the exhaust port are only the result of the variation of the liquid level in the chamber 23. The operations purge are thus triggered by the single withdrawal of the container and are performed independently of any external control or actuators ordered.
Dans le mode de réalisation illustré, le clapet d'échappement est déporté latéralement dans une position radialement vers l'intérieur par rapport au conduit de distribution, comme illustré par la figure 2. L'encombrement du bec de remplissage à la périphérie de la plate-forme pivotante est donc réduit au minimum, ce qui permet de diminuer les dimensions de la plate-forme pour un nombre donné de becs de remplissage.  In the illustrated embodiment, the exhaust valve is offset laterally in a radially inward position with respect to the distribution duct, as illustrated in FIG. 2. The space requirement of the filling spout at the periphery of the plate pivoting form is reduced to a minimum, which makes it possible to reduce the dimensions of the platform for a given number of filling spouts.
Bien entendu invention n'est pas limitée au mode de réalisation préféré décrit et est susceptible de variantes de réalisation qui apparaîtront à l'homme de métier sans sortir du cadre de l'invention tel que défini par les revendications .  Of course, the invention is not limited to the preferred embodiment described and is capable of alternative embodiments which will be apparent to those skilled in the art without departing from the scope of the invention as defined by the claims.
En particulier, bien que dans le mode de réalisation préféré l'évent d'échappement comporte une fente annulaire, on peut réaliser l'évent d'échappement sous forme d'un ou plusieurs perçages débouchant à la périphérie de la zone de distribution 6.  In particular, although in the preferred embodiment the exhaust vent comprises an annular slot, it is possible to realize the exhaust vent in the form of one or more bores opening out at the periphery of the distribution zone 6.
Bien que le bec que de remplissage ait été illustré avec un clapet de distribution commandée indépendamment d'une présence d'un récipient, le bec de remplissage selon l'invention peut également être réalisé avec un clapet de distribution dont l'ouverture est commandée par la mise en place d'un récipient. Bien que dans le mode de réalisation préféré le clapet d'échappement comporte un flotteur qui augmente la vitesse de fermeture du clapet, le clapet d'échappement peut également être réalisé avec une simple bille creuse. En outre bien que le flotteur ait été illustré sous une forme en cloche, ce qui permet de l'alléger et donc d'augmenter la vitesse de fermeture du clapet, le flotteur peut être réalisé sous une forme de flotteur fermé en particulier dans le cas d'un conditionnement d'un produit très sensible à la pollution tel que le lait. Although the spout filling has been illustrated with a dispensing valve controlled independently of the presence of a container, the filling spout according to the invention can also be made with a dispensing valve whose opening is controlled by setting up a container. Although in the preferred embodiment the exhaust valve has a float that increases the closing speed of the valve, the exhaust valve can also be realized with a simple hollow ball. In addition, although the float has been illustrated in a bell-shaped form, which makes it possible to lighten it and therefore to increase the closing speed of the valve, the float can be made in a form of closed float, in particular in the case packaging of a highly sensitive product such as milk.
En variante, le clapet d'échappement est déporté latéralement dans une position radialement vers l'extérieur par rapport au conduit de distribution. Le positionnement intérieur ou extérieur du clapet d' échappement permet de limiter l'encombrement du bec de remplissage selon une direction circonférentielle de la plateforme pivotante. L'adjonction du clapet d'échappement n'entraîne donc pas de diminution du nombre de bec de remplissage sur une plateforme de dimension donnée.  In a variant, the exhaust valve is offset laterally in a position radially outwardly with respect to the distribution duct. The internal or external positioning of the exhaust valve makes it possible to limit the size of the filling spout in a circumferential direction of the pivoting platform. The addition of the exhaust valve therefore does not lead to a reduction in the number of filling spouts on a platform of given dimension.
Selon un autre mode de réalisation préféré de l'invention, la source d'alimentation est à la pression atmosphérique de sorte que le remplissage est effectué sous pression atmosphérique. De préférence, le cycle de remplissage ne comprend pas de rinçage gazeux préalable des récipients à remplir. On obtient alors des temps de cycle de remplissage plus courts.  According to another preferred embodiment of the invention, the power source is at atmospheric pressure so that the filling is carried out at atmospheric pressure. Preferably, the filling cycle does not include prior gaseous rinsing of the containers to be filled. This results in shorter filling cycle times.
