Description

La présente invention a pour objet un dispositif de préhension et de maintien du goulot d'une outre, utilisé sur une machine de remplissage d'outres utilisées dans les systèmes de conditionnement de produits liquides et semi-liquides, alimentaires ou non, qui permettent notamment de prolonger la durée de conservation desdits produits.The subject of the present invention is a device for gripping and holding the neck of a skin, used on a machine for filling skins used in systems for packaging liquid and semi-liquid products, food or not, which allow in particular extend the shelf life of such products.

Ces outres sont faites de matière plastique plus ou moins souple, sont souvent, mais non limitativement, disposées dans une enveloppe se présentant sous la forme d'une boîte en carton, et sont munies d'un goulot équipé d'un bouchon, de préférence un robinet. L'outre permet le stockage du produit, tandis que l'enveloppe protège l'outre et facilite le transport.These skins are made of more or less flexible plastic material, are often, but not limited to, placed in an envelope in the form of a cardboard box, and are provided with a neck fitted with a stopper, preferably a tap. The skin allows the storage of the product, while the envelope protects the skin and facilitates transport.

Le remplissage des outres est réalisé de manière automatique sur des machines. Sur ces machines, les outres arrivent vides, le goulot déjà équipé d'un bouchon ou d'un robinet, lequel est enfoncé à force dans ledit goulot. L'opération de remplissage nécessite ainsi de réaliser préalablement à l'enlèvement du bouchon ou du robinet, puis à le remettre en place après remplissage. Il est par conséquent nécessaire de pouvoir maintenir le goulot pour en extraire le bouchon ou le robinet, et le maintenir pour l'opération de fermeture après remplissage.The filling of the skins is carried out automatically on machines. On these machines, the skins arrive empty, the neck already fitted with a stopper or a tap, which is forced into the said neck. The filling operation thus requires carrying out prior to the removal of the stopper or the valve, then putting it back in place after filling. It is therefore necessary to be able to hold the neck in order to extract the stopper or the valve therefrom, and to hold it for the closing operation after filling.

Dans un souci d'économie de matière première, les goulots d'origine ont été remplacés par des goulots utilisant moins de matière, il existe donc deux versions de goulot.In order to save raw material, the original necks have been replaced by necks using less material, there are therefore two neck versions.

Ainsi, en référence à la figure 1A on peut voir un goulot 1 en version classique, et sur la figure 1B un goulot 2 en version économique.Thus, with reference to FIG. 1A one can see a neck 1 in the classic version, and in FIG. 1B a neck 2 in the economical version.

Le goulot 1 comporte une collerette 10 soudée à la paroi P de l'outre, et qui est surmontée d'un manchon tubulaire 11 destiné à recevoir un bouchon ou un robinet, et qui est muni extérieurement à son extrémité libre d'un rebord annulaire périphérique 12, et dans sa partie intermédiaire d'un second rebord annulaire périphérique 13, ces éléments étant destinés au maintien du goulot lors de son saisissement.The neck 1 comprises a flange 10 welded to the wall P of the wineskin, and which is surmounted by a tubular sleeve 11 intended to receive a stopper or a tap, and which is provided externally at its free end with an annular rim peripheral 12, and in its intermediate part of a second peripheral annular flange 13, these elements being intended to maintain the neck during its seizure.

Le goulot 2 de version économique a été simplifié, il comporte également une collerette 20 soudée à la paroi P de l'outre, qui est surmontée d'un manchon tubulaire 21 destiné à recevoir un bouchon ou un robinet, par contre le manchon tubulaire 21 est plus court et il ne comporte qu'un seul rebord annulaire périphérique 22, disposé à son extrémité libre. Par ailleurs, l'épaisseur des différentes parois a été réduite.The neck 2 of the economic version has been simplified, it also comprises a flange 20 welded to the wall P of the addition, which is surmounted by a tubular sleeve 21 intended to receive a stopper or a tap, on the other hand the tubular sleeve 21 is shorter and has only one annular flange device 22, disposed at its free end. In addition, the thickness of the various walls has been reduced.

Si des modifications ont été apportées au goulot, on a conservé les dispositifs de préhension des machines de remplissage en effectuant uniquement des modifications de réglages.If modifications have been made to the neck, the gripping devices of the filling machines have been retained by only making changes to the settings.

La figure 2 montre un tel dispositif de préhension 3. Il se présente sous la forme d'une pince, comprenant essentiellement deux branches 30 et 31 montées pivotantes sur des axes distincts 32 et 33, munie à une extrémité 34 d'un vérin 35 dont l'action commande l'écartement ou le rapprochement des deux branches 30 et 31 à l'autre extrémité 36. Les deux branches 30 et 31 présentent du côté de cette extrémité 36, intérieurement au niveau de la zone de rapprochement, deux échancrures, respectivement 37 et 38, qui délimitent lors du rapprochement, une lumière 39 en forme de U.There picture 2 shows such a gripping device 3. It is in the form of a clamp, essentially comprising two branches 30 and 31 pivotally mounted on separate axes 32 and 33, provided at one end 34 with a cylinder 35 whose action controls the separation or the approximation of the two branches 30 and 31 at the other end 36. The two branches 30 and 31 have on the side of this end 36, internally at the level of the approximation zone, two notches, respectively 37 and 38 , which delimit during the approximation, a U-shaped light 39.

En pratique, l'outre est déplacée à plat, goulot 2 dirigé vers le haut, jusqu'à l'engagement du manchon 21 dans le fond de la lumière 39 qui constitue ainsi le siège récepteur dudit manchon 21, la collerette 20 passant sous les branches 30 et 31, tandis que la nervure annulaire 22 passe au-dessus.In practice, the skin is moved flat, neck 2 directed upwards, until the engagement of the sleeve 21 in the bottom of the slot 39 which thus constitutes the receiving seat of the said sleeve 21, the collar 20 passing under the branches 30 and 31, while the annular rib 22 passes above.

On comprendra que la pince 3 peut retenir le goulot 2 le temps de l'enlèvement du bouchon ou du robinet, ainsi que le temps du remplissage et de la fermeture, puis que l'ouverture des branches 30 et 31 sous l'action du vérin 35, libère le goulot 2 et donc l'outre.It will be understood that the clamp 3 can hold the neck 2 for the time of the removal of the plug or the valve, as well as the time of filling and closing, then that the opening of the branches 30 and 31 under the action of the cylinder 35, releases the neck 2 and therefore the wineskin.

On notera qu'un tel dispositif est décrit dans le document KR 101 278 451 .It will be noted that such a device is described in the document KR 101 278 451 .

Si un tel dispositif de préhension donnait entière satisfaction avec les goulots 1 de version classique, il n'en est pas de même avec les goulots 2 de la version économique. En effet la finesse des parois et donc la plus grande souplesse du manchon tubulaire 21, nécessite une grande précision de réglage de la largeur de la lumière 39, obtenue par l'intermédiaire du vérin 35, sachant qu'un maintien insuffisant peut être préjudiciable la fermeture, et qu'un serrage trop important peut déformer le manchon tubulaire rendant compliquée la mise en place du bouchon ou du robinet, en risquant une altération des parois en contact, ce qui est susceptible de générer des fuites.If such a gripping device gave complete satisfaction with the necks 1 of the classic version, it is not the same with the necks 2 of the economic version. Indeed the thinness of the walls and therefore the greater flexibility of the tubular sleeve 21, requires a high precision of adjustment of the width of the slot 39, obtained by means of the cylinder 35, knowing that insufficient maintenance can be detrimental to the closing, and that excessive tightening can deform the tubular sleeve making it difficult to fit the stopper or valve, risking damage to the walls in contact, which is likely to generate leaks.

On notera qu'il a également été proposé, notamment dans les documents EP 2 028 108 et US 2013/16040 , des machines de remplissage d'outre comprenant des dispositifs de pinces conçus pour envelopper entièrement, voire pratiquement entièrement, le goulot d'une outre. L'inconvénient de ce type de dispositif est que le goulot doit être positionné avec précision, et de préférence être immobile, pour pouvoir être saisi parfaitement, ce qui ne va pas de soi puisque ce goulot fait partie d'une outre souple.It should be noted that it has also been proposed, in particular in the documents EP 2 028 108 And US 2013/16040 , wineskin filling machines comprising gripper devices designed to envelop entirely, or even practically entirely, the neck of a goatskin. The disadvantage of this type of device is that the neck must be positioned with precision, and preferably be immobile, in order to be able to be grasped perfectly, which is not self-evident since this neck is part of a flexible skin.

Les dispositifs de pinces tels que celui représenté sur la figure 2 et celui décrit dans le document KR 101 278 451 , ne présentent pas cet inconvénient de défaut de positionnement, puisque le goulot est guidé en déplacement dans la lumière en U 39, jusqu'à l'emplacement de l'immobilisation. Toutefois, comme cela a déjà été évoqué, cette immobilisation n'est pas suffisante pour le maintien des goulots de version économique.Clamp devices such as the one shown in the figure 2 and the one described in the document KR 101 278 451 , do not have this disadvantage of positioning error, since the neck is guided in movement in the U-shaped slot 39, to the location of the immobilization. However, as has already been mentioned, this immobilization is not sufficient to maintain the bottlenecks of the economy version.

La présente invention a pour but de proposer un dispositif de préhension et de maintien du goulot d'une outre de conception nouvelle, permettant de résoudre les divers inconvénients précités, et notamment de pouvoir saisir les goulots, quelle qu'en soit la version.The object of the present invention is to propose a device for gripping and holding the neck of a skin of new design, making it possible to solve the various aforementioned drawbacks, and in particular to be able to grip the necks, whatever the version.

Le dispositif de préhension et de maintien du goulot d'une outre pour une machine de remplissage d'outres utilisées dans les systèmes de conditionnement de produits liquides et semi-liquides, alimentaires ou non, ledit goulot étant du type comprenant un manchon tubulaire garni à son extrémité libre d'un rebord annulaire périphérique extérieur, et ledit dispositif étant du type comprenant une lumière venant du rapprochement réversible de deux éléments, dans laquelle peut être déplacé et guidé ledit manchon jusqu'à être immobilisé dans le fond de ladite lumière, en forme de portion cercle de rayon correspondant à celui externe dudit manchon, et qui constitue le siège récepteur dudit goulot, et il se caractérise en ce qu'il comporte de plus un doigt mobile, conçu apte à se déplacer dans ladite lumière pour prendre une position active en venant fermer ladite lumière en U derrière ledit manchon et se placer sous ledit rebord, à cet effet, l'une des deux berges rectilignes qui délimitent ladite lumière en U, présente une découpe constituant un logement d'attente pour ledit doigt mobile lorsqu'il est en position inactive.The device for gripping and holding the neck of a skin for a machine for filling skins used in packaging systems for liquid and semi-liquid products, food or not, said neck being of the type comprising a tubular sleeve filled with its free end from an outer peripheral annular rim, and said device being of the type comprising a light coming from the reversible bringing together of two elements, in which said sleeve can be moved and guided until it is immobilized in the bottom of said light, in shape of a circle portion with a radius corresponding to that external of said sleeve, and which constitutes the receiving seat of said neck, and it is characterized in that it further comprises a movable finger, designed able to move in said slot to take up a position activates by coming to close said U-shaped opening behind said sleeve and to be placed under said rim, for this purpose, one of the two rectilinear banks which delimit the lad ite U-shaped light, has a cutout constituting a waiting housing for said movable finger when in the inactive position.

On comprendra que le manchon du goulot est ainsi entièrement entouré sans pression, en sorte d'en éviter une déformation, et son échappement.It will be understood that the sleeve of the neck is thus entirely surrounded without pressure, so as to avoid deformation thereof, and its escape.

Le déplacement du doigt depuis une position d'attente latérale extérieure au chemin de déplacement du goulot dans la lumière en U, permet de ne pas interférer dans le processus d'amenage des outres sur.The movement of the finger from a lateral waiting position outside the path of movement of the neck in the U-shaped slot makes it possible not to interfere in the process of feeding the skins on.

Selon une caractéristique additionnelle du dispositif de préhension et de maintien selon l'invention, il comprend une plaque dans laquelle est découpée la lumière, et le fond de ladite lumière est constitué des deux éléments mobiles en rapprochement et en éloignement sous l'action de moyens moteurs, en sorte de pouvoir prendre deux positions extrêmes à savoir l'une, en rapprochement, pour délimiter, au travers l'association de deux échancrures en forme d'arc de cercle chacune découpée dans l'un desdits deux éléments, une échancrure en forme de demi-cercle de diamètre correspondant à celui externe du manchon pour former le siège récepteur de ce dernier l'autre, en éloignement, pour délimiter une ouverture de dimensions insuffisantes à la retenue du manchon.According to an additional feature of the gripping and holding device according to the invention, it comprises a plate in which the slot is cut, and the bottom of said slot is made up of two elements moving towards each other and away from each other under the action of means motors, so as to be able to take two extreme positions, namely one, close together, to delimit, through the association of two indentations in the form of an arc of a circle each cut out in one of said two elements, an indentation in shape of a semicircle of diameter corresponding to that of the outer sleeve to form the receiving seat of the latter the other, away, to delimit an opening of insufficient dimensions to retain the sleeve.

Selon une autre caractéristique additionnelle du dispositif de préhension et de maintien selon l'invention, la lumière présente deux parties, une partie rectiligne pratiquée depuis le bord de la plaque, de largeur constante entre deux berges, qui débouche dans une seconde partie plus large, où agissent les deux éléments mobiles.According to another additional characteristic of the gripping and holding device according to the invention, the light has two parts, a rectilinear part made from the edge of the plate, of constant width between two banks, which opens into a second wider part, where the two moving parts act.

Selon une autre caractéristique additionnelle du dispositif de préhension et de maintien selon l'invention, la découpe dans laquelle le doigt peut demeurer en position d'attente, est en forme d'arc de cercle, tandis que ledit doigt est de forme complémentaire et est monté pivotant autour d'un axe auquel ladite découpe est coaxiale.According to another additional characteristic of the gripping and holding device according to the invention, the cutout in which the finger can remain in the waiting position is in the shape of an arc of a circle, while said finger is of complementary shape and is pivotally mounted about an axis with which said cutout is coaxial.

Selon une autre caractéristique additionnelle du dispositif de préhension et de maintien selon l'invention, l'extrémité libre du doigt mobile destinée à venir au contact du goulot, présente une découpe concave en arc de cercle de rayon correspondant à celui externe du manchon tubulaire, le déplacement dudit doigt étant réglé pour qu'en position active, ladite découpe concave soit concentrique à l'échancrure en forme de demi-cercle obtenue du rapprochement des échancrures des deux éléments mobiles, et constituant le siège récepteur du goulot.According to another additional characteristic of the gripping and holding device according to the invention, the free end of the movable finger intended to come into contact with the neck, has a concave cutout in the form of an arc of a circle of radius corresponding to that external of the tubular sleeve, the movement of said finger being adjusted so that, in the active position, said concave cutout is concentric with the indentation in the shape of a semicircle obtained by bringing together the indentations of the two mobile elements, and constituting the receiving seat of the neck.

Les avantages et les caractéristiques du dispositif de préhension et de maintien selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the gripping and holding device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.

En référence aux figures 3 et 4, on peut voir un dispositif 4 de préhension et de maintien selon l'invention, destiné à équiper une machine, non représentée, de remplissage d'outre. Ce dispositif 4 comporte une plaque 40 dans laquelle est réalisée une lumière 41 qui présente deux parties, une partie rectiligne 42 pratiquée depuis le bord de la plaque 40, de largeur constante entre deux berges 43 et 44, qui débouche dans une partie 45 plus large.With reference to figures 3 and 4 , one can see a device 4 for gripping and holding according to the invention, intended to equip a machine, not shown, for filling in addition. This device 4 comprises a plate 40 in which is made a slot 41 which has two parts, a rectilinear part 42 made from the edge of the plate 40, of constant width between two edges 43 and 44, which opens into a wider part 45 .

Il comporte également un moyen 5 réversible de préhension, qui comprend deux mors 50 et 51, agissant dans la partie 45 de la lumière 41, s'étendant dans le même plan que la plaque 40, montés pivotants autour de deux axes, respectivement 52 et 53, mobiles sous l'action d'un moyen moteur non visible, et dont les bords en regard sont munis chacun d'une échancrure, respectivement 54 et 55, en forme de quart de cercle.It also comprises a reversible gripping means 5, which comprises two jaws 50 and 51, acting in the part 45 of the slot 41, extending in the same plane as the plate 40, pivotally mounted about two axes, respectively 52 and 53, movable under the action of a non-visible motor means, and whose facing edges are each provided with an indentation, respectively 54 and 55, in the shape of a quarter circle.

On comprendra que lors du rapprochement des deux mors 50 et 51, la réunion des deux échancrures 54 et 55 forme une ouverture en demi-cercle, dans le prolongement de la partie rectiligne 42 de la lumière 41, pour pouvoir accueillir et bloquer le goulot 2, représenté sur la figure 4.It will be understood that when bringing together the two jaws 50 and 51, the meeting of the two indentations 54 and 55 forms a semicircular opening, in the extension of the rectilinear part 42 of the light 41, to be able to accommodate and block the neck 2 , shown on the figure 4 .

Les deux mors 50 et 51 sont liés en pivotement au travers de deux secteurs dentés, respectivement 56 et 57, chacun coaxial à un axe respectivement 52 et 53, en engrenés l'un dans l'autre.The two jaws 50 and 51 are connected in pivoting through two toothed sectors, respectively 56 and 57, each coaxial with an axis respectively 52 and 53, meshed one inside the other.

Le dispositif 4 comporte également un moyen de blocage 6 comprenant un doigt 60 mobile dans le plan de la plaque 40, et apte à venir se déplacer dans la partie rectiligne 42 de la lumière 41.The device 4 also comprises a blocking means 6 comprising a finger 60 movable in the plane of the plate 40, and capable of coming to move in the rectilinear part 42 of the slot 41.

A cet effet la plaque 40 comporte une découpe 46 qui débouche dans la partie rectiligne 42 de la lumière 41 au nouveau de la berge 43, tandis que le doigt 60, qui est de forme complémentaire de la découpe 46 qui lui sert de coulisse, est porté par un levier 61 monté pivotant sur la plaque 40 sous l'action un vérin 62, autour d'un axe 63 auquel la découpe 46 est coaxiale.For this purpose the plate 40 comprises a cutout 46 which opens into the rectilinear part 42 of the opening 41 at the new bank 43, while the finger 60, which is of complementary shape to the cutout 46 which serves as a slide, is carried by a lever 61 pivotally mounted on the plate 40 under the action of a cylinder 62, around an axis 63 to which the cutout 46 is coaxial.

Cette construction permet que le doigt demeure dans le même plan que la plaque 40, et donc de la lumière 41.This construction allows the finger to remain in the same plane as the plate 40, and therefore the light 41.

On comprendra que lors du pivotement du levier 61, le doigt 60 se déplace depuis la découpe 46 pour s'engager dans la partie rectiligne 42, jusqu'à ce que son extrémité libre 64 atteigne la partie 45 de la lumière 41, et plus exactement vienne au contact du manchon 21 du goulot 2, sous son rebord 22.It will be understood that when the lever 61 pivots, the finger 60 moves from the cutout 46 to engage in the rectilinear part 42, until its free end 64 reaches the part 45 of the slot 41, and more exactly comes into contact with the sleeve 21 of the neck 2, under its rim 22.

De manière avantageuse l'extrémité libre 64 du doigt 60 est de forme concave, en sorte que dans sa position de blocage du goulot 2 elle soit concentrique aux échancrures 54 et 55, la course du doigt 60 étant bien entendu calibrée en conséquence.Advantageously the free end 64 of the finger 60 is concave in shape, so that in its locking position of the neck 2 it is concentric with the indentations 54 and 55, the stroke of the finger 60 being of course calibrated accordingly.

En pratique, les mors 50 et 51 se rapprochent pour que les échancrures 54 et 55 forment un siège récepteur en forme de demi-cercle, le goulot 2, s'engage dans la partie rectiligne 42 de la lumière 41 jusqu'à venir en butée contre les échancrures 54 et 55, le vérin 62 est déployé, il fait pivoter le levier 63 qui entraîne le doigt 60 dans la lumière 41, jusqu'à venir au contact du manchon 21 sous le rebord 22. Après remplissage et rebouchage, le vérin 62 se rétracte, le doigt 60 retourne dans la découpe 46, les mors 50 et 51 s'écartent pour libérer l'outre.In practice, the jaws 50 and 51 come together so that the notches 54 and 55 form a receiving seat in the shape of a semicircle, the neck 2 engages in the rectilinear part 42 of the slot 41 until it comes into abutment against the notches 54 and 55, the cylinder 62 is deployed, it causes the lever 63 to pivot which drives the finger 60 into the slot 41, until it comes into contact with the sleeve 21 under the rim 22. After filling and resealing, the cylinder 62 retracts, the finger 60 returns to the cutout 46, the jaws 50 and 51 move apart to free the skin.

Le dispositif de préhension et de maintien selon l'invention autorise un parfait maintien du goulot 2 sans pression, quelles que soit les caractéristiques de celui-ci.The gripping and holding device according to the invention allows perfect holding of the neck 2 without pressure, whatever the characteristics of the latter.
