Abstract
Description
La présente invention concerne un dispositif diviseur de jet pour tête de remplissage.The present invention relates to a jet divider device for filling head.
Les machines destinées au remplissage de liquide présentent différents types de clapets de fermeture ou de robinets distributeurs. Par ailleurs, afin de maintenir le liquide en suspension par effet de tension superficielle et éviter ainsi après la fermeture la formation de gouttes venant souiller l'emballage qui vient d'être rempli, on prévoit des dispositifs diviseurs de jet tels que des grilles réalisées à partir de fils entrecroisés ou d'une plaque perforée (FR-A-209 8782).Machines for filling liquids have different types of shut-off valves or dispensing valves. In addition, in order to keep the liquid in suspension by the effect of surface tension and thus avoid, after closing, the formation of drops which contaminate the packaging which has just been filled, provision is made for jet dividing devices such as grids made at from crisscrossed wires or from a perforated plate (FR-A-209 8782).
D'autre part, on s'est aperçu que certains liquides tels que le lait frais, le jus de fruit ou des produits du type ammoniaqué ont tendance à mousser lors du remplissage et à perturber celui-ci. L'utilisation de dispositifs diviseurs de jet tels que des grilles ou des plaques perforées a pour effet de créer localement un écoulement laminaire qui réduit la quantité de mousse produite et améliore le remplissage.On the other hand, it has been observed that certain liquids such as fresh milk, fruit juice or products of the ammonia type tend to foam during filling and to disturb it. The use of jet dividing devices such as grids or perforated plates has the effect of locally creating a laminar flow which reduces the amount of foam produced and improves filling.
Ces dispositifs sont généralement satisfaisants mais dans le cas de liquides chargés de pulpes tels que le jus d'orange ou le jus de goyave, les pulpes ont tendance à se mettre à cheval sur les éléments diviseurs de l'écoulement et se trouvent plaquées dans cette position par la pression de l'écoulement. La quantité de pulpe ainsi bloquée par le diviseur de jet a tendance à augmenter rapidement et à former un tapis de pulpes obstruant complètement les ouvertures du dispositif diviseur de jet et bloquant l'écoulement du produit à conditionner. Il est alors nécessaire de démonter la tête de remplissage et de décharger le dispositif diviseur de jet de la pulpe qu'il contient. Indépendamment de la perte de temps que cela représente, cela suppose une manipulation des différents éléments de la tête de remplissage qui est particulièrement défavorable dans le cas de conditionnement d'un produit devant être conditionné de façon aseptique.These devices are generally satisfactory, but in the case of liquids loaded with pulps such as orange juice or guava juice, the pulps tend to overlap the dividing elements of the flow and are stuck in this position by flow pressure. The quantity of pulp thus blocked by the jet divider tends to increase rapidly and to form a carpet of pulps completely obstructing the openings of the jet divider device and blocking the flow of the product to be conditioned. It is then necessary to dismantle the filling head and unload the jet divider device from the pulp it contains. Regardless of the loss of time that this represents, this involves manipulation of the various elements of the filling head which is particularly unfavorable in the case of packaging a product to be packaged aseptically.
Il est possible d'éviter le colmatage du dispositif diviseur de jet en augmentant la dimension des ouvertures dans la grille ou la plaque perforée, mais alors l'écoulement dans le dispositif diviseur de jet n'est plus laminaire et l'on se retrouve confronté aux problèmes de mousse qui ont été invoqués plus haut.It is possible to avoid clogging of the jet divider device by increasing the size of the openings in the grid or the perforated plate, but then the flow in the jet divider device is no longer laminar and we are confronted to the foam problems that were mentioned above.
La présente invention a pour objet de proposer un dispositif diviseur de jet pour tête de remplissage ayant une structure permettant d'assurer un écoulement continu des pulpes ou autres éléments filandreux contenus dans le liquide tout en maintenant un écoulement laminaire évitant l'émulsion du produit lors de sa chute dans l'emballage.The object of the present invention is to provide a jet divider device for a filling head having a structure making it possible to ensure a continuous flow of the pulps or other stringy elements contained in the liquid while maintaining a laminar flow avoiding the emulsion of the product during of its fall in the packaging.
Pour la réalisation de cet objet, on prévoit selon l'invention un dispositif diviseur de jet pour tête de remplissage comportant une série d'éléments réalisant un cloisonnement transversal à l'écoulement, caractérisé en ce que les éléments comportent des bords supérieurs décalés axialement les uns par rapport aux autres et un moyen donnant une composante transversale s'étendant en saillie par rapport à la paroi de l'élément de cloisonnement.To achieve this object, there is provided according to the invention a jet divider device for filling head comprising a series of elements providing a partitioning transverse to the flow, characterized in that the elements comprise upper edges offset axially the relative to each other and means giving a transverse component projecting from the wall of the partition element.
Selon une caractéristique plus particulière de l'invention, les éléments de cloisonnement sont des éléments annulaires concentriques et le moyen donnant une composante transversale est constitué d'une collerette.According to a more particular characteristic of the invention, the partitioning elements are concentric annular elements and the means giving a transverse component consists of a flange.
Selon d'autres caractéristiques plus particulières de l'invention, la collerette portée par un élément annulaire est perpendiculaire à la paroi de celui-ci, elle est disposée à la partie supérieure de l'élément annulaire, les éléments annulaires sont de forme tronconique, les éléments annulaires sont maintenus en relation d'écartement au moyen d'au moins trois bras radiaux s'étendant dans une direction opposée à la collerette.According to other more specific features of the invention, the collar carried by an annular element is perpendicular to the wall of the latter, it is arranged at the upper part of the annular element, the annular elements are of frustoconical shape, the annular elements are maintained in spacing relation by means of at least three radial arms extending in a direction opposite to the flange.
D'autres caractéristiques et avantages apparaîtront au cours de la description suivante faite en relation avec les dessins annexés, parmi lesquels :Other characteristics and advantages will appear during the following description given in relation to the appended drawings, among which:
La figure 1 est une vue en coupe diamétrale suivant la ligne 1:1 de la figure 2 d'un manchon porte-grilles équipé d'un dispositif diviseur de jet selon l'invention; etFigure 1 is a diametrical sectional view along line 1: 1 of Figure 2 of a grid-carrying sleeve equipped with a jet divider device according to the invention; and
La figure 2 est une vue en perspective agrandie 15 d'un élément de cloisonnement du dispositif diviseur de jet selon l'invention.Figure 2 is an enlarged perspective view of a partition element of the jet divider device according to the invention.
En se reportant aux figures, le dispositif selon l'invention comporte une série d'éléments de cloisonnement généralement désignés en 1 se présentant sous forme d'éléments annulaires tronconiques 2 de diamètres variés, comportant à leur partie supérieure une collerette 3 disposée à la partie supérieure de l'élément tronconique 2 et s'étendant radialement en saillie vers l'extérieur. Chaque élément 1 comporte en outre trois bras radiaux 4 s'étendant vers l'intérieur de sorte que piusieurs éléments 1 de diamètre décroissant peuvent être emboîtés les uns dans les autres, la collerette 3 de chaque élément reposant alors sur les extrémités internes des bras 4 de l'élément 1 de diamètre immédiatement supérieur.Referring to the figures, the device according to the invention comprises a series of partitioning elements generally designated at 1 in the form of frustoconical
Dans la réalisation représentée, les éléments 1 ont une longueur décroissante en allant de l'élément de plus petit diamètre à l'élément de plus grand diamètre de sorte que lorsque les différents éléments sont emboîtés ils constituent un ensemble ayant un bord inférieur à un niveau sensiblement constant.In the embodiment shown, the elements 1 have a decreasing length from the element of smaller diameter to the element of larger diameter so that when the different elements are nested they constitute an assembly having an edge less than a level substantially constant.
De plus, dans la réalisation représentée, l'élément de plus grand diamètre désigné en 5 ne comporte pas de collerette extérieure et a une surface extérieure sensiblement cylindrique de sorte que sa surface extérieure et sa surface inférieure s'appuient sur un épaulement interne réalisé dans un manchon porte-grilles généralement désigné en 6. On notera à ce propos que l'élément 5 pourrait être de structure exactement identique à celle des autres éléments de collerette 3 s'appuyant alors sur l'épaulement interne du manchon 6 et la partie tronconique s'étendant vers le bas du manchon.In addition, in the embodiment shown, the element of larger diameter designated at 5 does not have an outer flange and has a substantially cylindrical outer surface so that its outer surface and its lower surface rest on an internal shoulder produced in a grid-carrying sleeve generally designated at 6. It will be noted in this connection that the element 5 could be of structure exactly identical to that of the
Dans la réalisation représentée, le manchon porte-grilles comporte également un bras transversal 7 supportant un doigt 8, permettant de réaliser un nettoyage de la tête de remplissage sans démontage du manchon porte-grilles ainsi que cela est décrit dans le brevet français n° 2 290 259. Une telle caractéristique n'est bien évidemment pas nécessaire pour un fonctionnement correct du dispositif diviseur de jet selon l'invention qui peut être adap, tée à tout élément porte-grilles qu'il soit démontable ou non.In the embodiment shown, the grid sleeve also includes a transverse arm 7 supporting a finger 8, making it possible to carry out cleaning of the filling head without dismantling the grid sleeve as described in French patent n ° 2 290 259. Such a characteristic is obviously not necessary for the correct functioning of the jet divider device according to the invention which can be adapted to any grid-carrying element whether it is removable or not.
Ainsi, qu'on peut le voir sur la figure 1, dans la réalisation représentée, l'élément de cloisonnement central 9 est généralement cylindrique et comporte trois bras radiaux 10 sensiblement analogues au bras 4 mais s'étendant cette fois vers l'extérieur et sur lesquels vient s'appuyer une rondelle annulaire 11 emmanchée à force dans le manchon 6 afin de maintenir en place les différents éléments 1 du dispositif diviseur de jet. Une fois encore, une telle disposition n'est pas strictement nécessaire au bon fonctionnement du diviseur de jet selon l'invention. En effet, la pièce centrale peut être tronconique comme les autres pièces, elle peut également être pleine mais une pièce creuse est toujours préférée car elle améliore la qualité du jet. De même, on peut adopter d'autres moyens pour maintenir en place le dispositif diviseur de jet sans pour autant sortir du cadre de l'invention.Thus, as can be seen in FIG. 1, in the embodiment shown, the
Lors du remplissage, chaque collerette 3 va créer au moins partiellement une chicane avec le bord supérieur de l'élément 1 qui lui est immédiatement adjacent et l'écoulement de liquide tout en étant divisé, va se trouver orienté localement à ce niveau radialement vers l'intérieur de sorte qu'une pulpe qui aurait tendance à se disposer à cheval sur le bord supérieur d'un élément 1 va être entraînée radialement et va donc s'écouler avec le liquide empêchant ainsi le colmatage de la tête de remplissage. A ce propos, on notera que les bras 4 sont suffisamment écartés les uns des autres pour qu'aucun pont de pulpe ne puisse se former entre eux. La pulpe qui se met à cheval sur ces bras glisse après quelques temps de sorte qu'aucune accumulation ne se produit.During filling, each
Il apparaît clairement que d'autres formes de réalisation peuvent être adoptées sans sortir du cadre de l'invention. En particulier, les éléments 1 peuvent être des éléments cylindriques ou au contraire avoir une forme tronconique plus prononcée, l'effet de pyramide des différents éléments 1 emboîtés les uns dans les autres peut être augmenté en disposant les collerettes 3 à un niveau de la paroi 3 décalée par rapport au bord supérieur de celle-ci. En effet, c'est la coopération d'une collerette avec le bord supérieur de l'élément adjacent qui est importante et non la coopération des bords supérieurs entre eux. De plus, les collerettes peuvent être disposées à l'intérieur des parois 2 tandis que les bras 4 s'étendent vers l'extérieur, la forme de pyramide des bords supérieurs des éléments 1 étant alors inversée par rapport à celle représentée et la composante radiale de l'écoulement se faisant alors de l'intérieur vers l'extérieur. On notera également que la collerette n'est pas nécessairement perpendiculaire à la paroi de l'élément 1, mais doit seulement avoir une position propre à engendrer une composante transversale au bord supérieur de l'élément adjacent.It is clear that other embodiments can be adopted without departing from the scope of the invention. In particular, the elements 1 can be cylindrical elements or on the contrary have a more pronounced frustoconical shape, the pyramid effect of the different elements 1 nested one inside the other can be increased by placing the
La présente invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits, elle est au contraire susceptible de modifications et de variantes qui apparaîtront à l'homme de l'art,The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and variants which will appear to those skilled in the art,
