Description

Il est bien connu que, lors du remplissage d'un fût au moyen d'un liquide, il doit être laissé un petit espace vide, appelé "creux de route", afin de permettre au récipient d'absorber les variations de volume du liquide dues aux fluctuations de température. Sans ce "creux de route" le récipient risquerait de se déformer, mais la variation de volume du liquide sous l'effet du changement de température provoque une variation correspondante de la pression du gaz composant le "creux de route" ; par exemple, lors du remplissage du fût par un produit ayant une température beaucoup plus élevée que la température ambiante, le refroidissement jusqu'à la température normale provoque une contraction à la fois du liquide et du gaz composant le "creux de route". La pression de ce gaz diminue donc en fonction de la différence de température et du coefficient de dilatation thermique du produit contenu dans le fût.It is well known that, when filling a barrel with a liquid, a small empty space must be left, called a "trough", in order to allow the container to absorb the variations in volume of the liquid. due to temperature fluctuations. Without this "trough" the container would risk deforming, but the change in volume of the liquid under the effect of the temperature change causes a corresponding variation in the pressure of the gas making up the "trough"; for example, when filling the barrel with a product having a temperature much higher than room temperature, cooling to normal temperature causes a contraction of both the liquid and the gas making up the "trough". The pressure of this gas therefore decreases as a function of the temperature difference and the coefficient of thermal expansion of the product contained in the barrel.

Pour éviter que cette variation ne provoque une déformation du fût lui-même, il est donc nécessaire de déterminer la forme et la nature du récipient, le volume du "creux de route" et la température maximale permise au cours du remplissage en fonction des coefficients de dilatation thermique du produit enfermé dans le fût.To avoid this variation causing deformation of the barrel itself, it is therefore necessary to determine the shape and nature of the container, the volume of the "trough" and the maximum temperature allowed during filling as a function of the coefficients thermal expansion of the product enclosed in the barrel.

Or, pour des raisons économiques, il n'est pas possible de disposer de fûts particuliers pour chaque type de produit et l'on utilise un récipient de type unique pour la majorité des cas de remplissage.However, for economic reasons, it is not possible to have special drums for each type of product and a single type container is used for the majority of filling cases.

La déformation des fûts sous l'effet d'une contraction thermique pose donc un problème important aux stations de remplissage des fûts, chaque fois que le remplissage doit être fait à chaud.The deformation of the barrels under the effect of a thermal contraction therefore poses a significant problem at the barrel filling stations, each time the filling must be done hot.

On a bien proposé, d'après le GB-A-875 833, d'accroitre la pression du "creux de route" en assurant la fermeture au moyen d'un appareil comportant une enveloppe cylindrique qui est munie d'un orifice de communication avec une source de gaz, porte à une extrémité des moyens d'étanchéité de son contact avec la périphérie de l'orifice du récipient, et contient un plongeur d'enfoncement d'un bouchon, ce plongeur étant actionné lorsque la pression désirée est atteinte dans le récipient, après coupure de l'arrivée du gaz.We have proposed, according to GB-A-875 833, to increase the pressure of the "trough of the road" by ensuring the closing by means of an apparatus comprising a cylindrical envelope which is provided with an orifice for communication with a gas source, carries at one end sealing means of its contact with the periphery of the orifice of the container, and contains a plunger for driving a plug, this plunger being actuated when the desired pressure is reached in the container, after cutting off the gas supply.

Malheureusement cet appareil ne peut être utilisé qu'avec un type particulier de récipients et permet difficilement de contrôler la pression réelle du "creux de route". Il n'est par suite pas adapté au remplissage d'un grand nombre de récipients et notamment des fûts métalliques ou analogues.Unfortunately, this device can only be used with a particular type of container and makes it difficult to control the real pressure of the "trough of the road". It is therefore not suitable for filling a large number of containers and in particular metal drums or the like.

La présente invention a pour but de remédier à cet inconvénient en proposant un dispositif de fermeture qui permette de contrôler la pression du gaz dans le "creux de route", jusqu'à la fermeture complète du récipient, quel que soit ce dernier.The object of the present invention is to remedy this drawback by proposing a closure device which makes it possible to control the pressure of the gas in the "trough of the road", until the container is completely closed, whatever the latter.

Cette invention a en effet pour objet un dispositif de fermeture, qui comporte une enveloppe cylindrique qui est munie d'un orifice de communication avec une source de gaz sous pression et porte, à une extrémité, des moyens d'étanchéité de son contact avec la périphérie de la bonde* du fût, et un dispositif d'obturation monté à l'intérieur de cette enveloppe, caractérisé en ce que le dispositif d'obturation est porté par un piston qui est mobile à coulissement étanche dans l'enveloppe entre une position de maintien de l'obturateur loin de la bonde, permettant l'entrée du gaz sous pression dans le fût, et une position de mise en place de l'obturateur et d'isolement du fût de la source de gaz, et en ce qu'un détecteur de pression est monté dans l'enveloppe au voisinage de l'orifice de communication avec la source de gaz.The subject of this invention is in fact a closure device, which comprises a cylindrical envelope which is provided with an orifice for communication with a source of pressurized gas and carries, at one end, means for sealing its contact with the periphery of the bung * of the barrel, and a closure device mounted inside this envelope, characterized in that the closure device is carried by a piston which is movable with sliding sliding in the envelope between a position holding the shutter away from the plug, allowing the entry of pressurized gas into the barrel, and a position for fitting the shutter and isolation from the barrel of the gas source, and in that a pressure detector is mounted in the envelope in the vicinity of the orifice for communication with the gas source.

Un tel dispositif permet le maintien de la communication entre la source de fluide sous pression et le fût, alors que la pression dans ce dernier a atteint la valeur désirée, et la fermeture du fût sans risque de modification de cette pression.Such a device allows the communication between the pressurized fluid source and the barrel to be maintained, while the pressure in the latter has reached the desired value, and the barrel to be closed without risk of modification of this pressure.

Par ailleurs, la réalisation extrêmement simple de ce dispositif ainsi que sa facilité de mise en place permettent son utilisation sur des fûts de type classique, quel que soit leur mode de fermeture.Furthermore, the extremely simple embodiment of this device as well as its ease of installation allow it to be used on drums of conventional type, whatever their method of closure.

La description ci-dessous d'un mode de réalisation donné à titre d'exemple non limitatif, et représenté aux dessins annexés, fera d'ailleurs ressortir les avantages et caractéristiques de l'invention.The description below of an embodiment given by way of nonlimiting example, and represented in the appended drawings, will moreover highlight the advantages and characteristics of the invention.

Sur ces dessins :

  • - la fig. 1 est une vue en coupe longitudinale du dispositif de l'invention en position sur le fût, pendant la formation du "creux de route" ;
  • - la fig. 2 est une vue analogue à la figure 1 montrant le dispositif après la mise en place de l'obturateur.
In these drawings:
  • - fig. 1 is a view in longitudinal section of the device of the invention in position on the barrel, during the formation of the "trough of the road";
  • - fig. 2 is a view similar to FIG. 1 showing the device after the installation of the shutter.

Le dispositif selon l'invention comporte une enveloppe cylindrique 1 qui est munie, à l'une de ses extrémités, de moyens permettant son application étanche sur un fût 2, autour de la bonde 3 de celui-ci.The device according to the invention comprises a cylindrical envelope 1 which is provided, at one of its ends, with means allowing its sealed application on a barrel 2, around the bung 3 thereof.

Dans le mode de réalisation représenté, la bonde 3 est entourée par une collerette 4, filetée intérieurement et munie d'un bourrelet extérieur 5. L'enveloppe 1 comporte, par suite, simplement une rainure 6 dans laquelle est logé un joint torique 8 dont le diamètre est suffisant pour qu'il soit serré de manière rigoureusement étanche contre le bourrelet 5, lorsque l'enveloppe 1 est emboîtée autour de la collerette 4.In the embodiment shown, the drain 3 is surrounded by a flange 4, internally threaded and provided with an external bead 5. The casing 1 therefore comprises simply a groove 6 in which is housed an O-ring 8 of which the diameter is sufficient for it to be tightly tightened tightly against the bead 5, when the envelope 1 is fitted around the flange 4.

L'enveloppe 1 est également ouverte à son extrémité opposée à la rainure 6 et contient un piston 10, allongé et creux, qui supporte un moteur 12 d'entraînement d'une clé 14 de mise èn place de I'obturafeur La cle 14 comporte une tige 16 montée rotative,au moyen de roulements à billes 18,dans la paroi du piston 10 et faisant saillie à l'extérieur de ce dernier, en regard de la rainure 6 pour porter une tête 20 munie de moyens 22 de retenue d'un obturateur 24.The casing 1 is also open at its end opposite to the groove 6 and contains a piston 10, elongated and hollow, which supports a motor 12 for driving a key 14 for putting the shutter in place. The key 14 comprises a rod 16 rotatably mounted, by means of ball bearings 18, in the wall of the piston 10 and protruding outside the latter, opposite the groove 6 to carry a head 20 provided with means 22 for retaining a shutter 24.

Les moyens de retenue 22 sont, par exemple, constitués par un aimant et ils retiennent une capsule 24 d'obturation de la bonde, qui est filetée extérieurement et destinée à être vissée dans la collerette 4.The retaining means 22 are, for example, constituted by a magnet and they retain a capsule 24 for closing the plug, which is externally threaded and intended to be screwed into the flange 4.

Le piston creux 10 est monté à coulissement étanche à l'intérieur de l'enveloppe 1, grâce à un joint torique 26 en contact avec la paroi de cette enveloppe. Il comporte par ailleurs, au voisinage de son extrémité opposée à la tête 20, une partie 28 de plus grand diamètre qui coulisse dans un alésage 30, élargi, de l'enveloppe 1 et forme ainsi un vérin à double effet de commande du déplacement du piston 10 dans l'enveloppe 1.The hollow piston 10 is mounted with sealed sliding inside the casing 1, thanks to an O-ring 26 in contact with the wall of this casing. It also comprises, in the vicinity of its end opposite to the head 20, a portion 28 of larger diameter which slides in a widened bore 30 of the casing 1 and thus forms a double-acting cylinder for controlling the movement of the piston 10 in casing 1.

L'enveloppe 1 comporte également un ajutage 32 de mise en communication avec une source de fluide sous pression, qui n'a pas été représentée pour ne pas compliquer le dessin. Un détecteur de pression 34 est monté, par exemple dans cet ajutage, de façon à contrôler la pression qui règne dans cette partie de l'enveloppe 1, entre le piston et le fût.The casing 1 also includes a nozzle 32 for communicating with a source of pressurized fluid, which has not been shown so as not to complicate the drawing. A pressure detector 34 is mounted, for example in this nozzle, so as to control the pressure prevailing in this part of the casing 1, between the udder tone and cask.

Lorsque le dispositif est dans la position représentée sur la figure 1, c'est-à-dire lorsqu'il vient d'être mis en place sur le fat 2 et que le piston 10 est éloigné de la bonde 3, le gaz, ou les vapeurs, destiné à constituer le "creux de route" est introduit dans le füt 2 par l'ajutage 32, qui est en communication avec la source de pression. La tête 20 de la clé 14 ainsi que la capsule 24 étant écartées de la bonde 3, ce gaz pénètre librement dans le fat. Dès que le détecteur 34 signale que la pression désirée pour le "creux de route" est atteinte, le vérin, constitué par le piston 28 et la partie élargie 30 de l'enveloppe 1, est actionné, du fluide sous pression étant introduit dans la chambre supérieure 36 de ce vérin par un orifice 38, et le moteur 12 est mis en route.When the device is in the position shown in FIG. 1, that is to say when it has just been put in place on the fat 2 and the piston 10 is distant from the plug 3, the gas, or the vapors, intended to constitute the "trough of the road" is introduced into the füt 2 through the nozzle 32, which is in communication with the pressure source. The head 20 of the key 14 and the capsule 24 being spaced from the plug 3, this gas freely enters the fat. As soon as the detector 34 signals that the desired pressure for the "trough" is reached, the jack, constituted by the piston 28 and the enlarged part 30 of the casing 1, is actuated, fluid under pressure being introduced into the upper chamber 36 of this jack through an orifice 38, and the motor 12 is started.

L'ensemble du piston 10 et de la clé 14 est, par suite, repoussé en direction de la bonde 3 jusqu'au moment où la capsule 24 entre en contact avec la collerette 4 tandis que le füt 2 reste en communication avec la source de gaz sous pression et est maintenu, par exemple au moyen d'un détendeur, à la pression déterminée de réglage.The assembly of the piston 10 and of the key 14 is consequently pushed back towards the plug 3 until the capsule 24 comes into contact with the flange 4 while the barrel 2 remains in communication with the source of gas under pressure and is maintained, for example by means of a pressure reducer, at the determined setting pressure.

La rotation du moteur 12 et de la clé 14 se combine ensuite à l'action du vérin pour provoquer le vissage de la capsule 24 dans le filetage de la collerette 4 et la poursuite du déplacement axial de l'ensemble du piston 10 et du moteur 12,jusqu'au moment où la capsule 24 est complètement vissée dans la collerette 4 et atteint la position représentée sur la figure 2.The rotation of the motor 12 and of the key 14 is then combined with the action of the jack to cause the screwing of the capsule 24 in the thread of the flange 4 and the continued axial movement of the assembly of the piston 10 and the motor. 12, until the capsule 24 is completely screwed into the flange 4 and reaches the position shown in FIG. 2.

Le moteur 12 peut alors être arrêté et la communication avec la source de gaz sous pression fermée.The engine 12 can then be stopped and communication with the source of pressurized gas closed.

Bien que la communication entre l'ajutage 32 et la source de gaz soit maintenue pendant toute l'opération de fermeture, la pression à l'intérieur de l'enveloppe 1, entre la tête 20 et le piston 10, est toujours nettement inférieure à celle du fluide agissant dans la chambre 36, de sorte qu'elle ne s'oppose pas au déplacement de ce piston sous l'action du moteur 12, ce qui facilite la mise en place de la capsule.Although the communication between the nozzle 32 and the gas source is maintained throughout the closing operation, the pressure inside the casing 1, between the head 20 and the piston 10, is still clearly lower than that of the fluid acting in the chamber 36, so that it does not oppose the displacement of this piston under the action of the motor 12, which facilitates the positioning of the capsule.

Le fût étant fermé, le dispositif de fermeture, et notamment l'enveloppe 1, peut facilement être retiré en l'éloignant de la collerette 3, l'élasticité du joint 8 permettant ce déplacement.The barrel being closed, the closing device, and in particular the casing 1, can easily be removed by moving it away from the collar 3, the elasticity of the seal 8 allowing this movement.

Il apparaît clairement que le dispositif qui vient d'être décrit permet également de mettre en place, sur une bonde de füt, des obturateurs de types différents de celui qui vient d'être décrit. Par exemple, la tête 20 pourrait porter un obturateur destiné à être fixé par engagement à baïonnette ou par un autre système approprié. Dans tous les cas, la fermeture s'effectue de la même manière, la clé 14 pouvant se déplacer en rotation et/ou axialement, selon les besoins, après l'isolement du füt 2 et de l'ajutage 32 en liaison avec la source de fluide sous pression.It clearly appears that the device which has just been described also makes it possible to install, on a waste plug, shutters of different types from that which has just been described. For example, the head 20 could carry a shutter intended to be fixed by bayonet engagement or by another suitable system. In all cases, the closure is carried out in the same manner, the key 14 being able to move in rotation and / or axially, as required, after the isolation of the barrel 2 and the nozzle 32 in connection with the source. pressurized fluid.

Le fût fermé au moyen d'un tel dispositif présente une surpression intérieure, de telle sorte qu'après le refroidissement du liquide qui le remplit, le vide dû à la contraction de ce liquide est compensé par la surpression déterminée prévue initialement. Les risques d'implosion du füt sont alors éliminés.The barrel closed by means of such a device has an internal overpressure, so that after the liquid which fills it has cooled, the vacuum due to the contraction of this liquid is compensated by the determined overpressure initially provided for. The risk of implosion of the drum is then eliminated.

La pression du contenu du fût au moment de la fermeture de ce dernier peut, par ailleurs, facilement être adaptée à chaque produit de remplissage grâce à un simple réglage du seuil de déclenchement de l'obturation. L'utilisation d'un récipient de type unique ne présente donc plus d'inconvénient.The pressure of the contents of the barrel at the time of closing of the latter can, moreover, easily be adapted to each filling product by means of a simple adjustment of the shutter release threshold. The use of a single type container therefore no longer has any drawbacks.

Bien entendu, l'alimentation en gaz sous pression, de même que l'actionnement du vérin et le démarrage du moteur 12, peuvent être obtenus par tout moyen approprié et même si désiré, être déclenchés manuellement par un opérateur averti par le détecteur de pression, éventuellement associé à une alarme.Of course, the supply of pressurized gas, as well as the actuation of the jack and the starting of the engine 12, can be obtained by any appropriate means and even if desired, be triggered manually by an operator notified by the pressure detector, possibly associated with an alarm.

De préférence toutefois, on utilise une commande automatique, par exemple pneumatique, soumise au détecteur 34 qui provoque l'actionnement du vérin et du moteur 12, soit simultanément dès que la pression de réglage est atteinte dans l'enceinte 1, soit successivement, le.moteur 12 ne démarrant que lorsque la capsule 24 est en contact avec la bonde du fùt, ainsi que l'arrêt de ces entraine- ments à la fin de la fermeture.Preferably, however, an automatic control, for example pneumatic, is used, subject to the detector 34 which causes the actuator and the motor 12 to be actuated, either simultaneously as soon as the adjustment pressure is reached in the enclosure 1, or successively, the .motor 12 starting only when the capsule 24 is in contact with the bung of the drum, as well as the stopping of these drives at the end of the closure.

De même le moteur 12 est de préférence un moteur pneumatique de sorte que tout le dispositif fonctionne à l'air ou au gaz et peut même être branché sur une source unique. La réalisation du dispositif est ainsi simplifiée mais aussi sa sécurité, de sorte qu'il peut être utilisé quelle que soit la nature du liquide contenu dans ce füt.Similarly, the motor 12 is preferably a pneumatic motor so that the entire device operates with air or gas and can even be connected to a single source. The realization of the device is thus simplified but also its security, so that it can be used regardless of the nature of the liquid contained in this container.
