Description

La présente invention a essentiellement pour objet un procédé d'operculage automatique de récipients, tels que des gobelets, destinés par exemple à contenir une denrée alimentaire quelconque.The present invention essentially relates to an automatic sealing process for containers, such as cups, intended for example to contain any foodstuff.

Elle vise également un dispositif pour l'exécution de ce procédé ainsi qu'une machine de conditionnement de récipients qui est équipé de ce dispositif.It also relates to a device for carrying out this process as well as a container packaging machine which is equipped with this device.

On a déjà proposé des dispositifs pour obturer automatiquement des récipients ou gobelets à l'aide d'opercules constitués par une feuille métallique très mince.Devices have already been proposed for automatically closing containers or cups with the aid of lids constituted by a very thin metal sheet.

Ces dispositifs pouvaient être constitués par un tambour rotatif équipé de ventouses aptes à saisir les opercules et, après rotation du tambour, à les déposer sur les gobelets précédemment remplis d'une denrée quelconque.These devices could consist of a rotary drum fitted with suction cups capable of gripping the lids and, after rotation of the drum, of depositing them on the cups previously filled with any commodity.

Mais, avec ce genre de dispositif, on ne peut utiliser que des opercules possédant une dimension bien déterminée. De plus, la stérilisation des deux faces de l'opercule, qui est indispensable quand il s'agit d'obturer des récipients contenant une denrée alimentaire, ne pouvait pas être réalisée complètement et efficacement. Aussi, on était obligé de stériliser l'ensemble de l'appareillage de dépose des opercules, ce qui est une solution compliquée et coûteuse. Enfin, il convenait de prévoir des moyens permettant le centrage de l'opercule sur le pot lors de la dépose et avant que soit effectué le thermoscellage de l'opercule. Cela compliquait le système et les moyens de centrage ne pouvaient évidemment convenir que pour une dimension particulière d'opercule.However, with this kind of device, it is only possible to use lids with a well-defined dimension. In addition, the sterilization of both sides of the cover, which is essential when it comes to closing containers containing a foodstuff, could not be carried out completely and effectively. Also, we had to sterilize the entire device for removing the lids, which is a complicated and expensive solution. Finally, it was necessary to provide means allowing the centering of the lid on the jar during removal and before the sealing of the lid is carried out. This complicated the system and the centering means could obviously only be suitable for a particular size of cover.

La présente invention a pour but de s'affranchir de toutes les contraintes ci-dessus en proposant un procédé et un dispositif d'operculage automatique de récipients qui peuvent utiliser des opercules de dimensions quelconques, lesquels sont stérilisés sur les deux faces d'une manière efficace et sans la nécessité d'un appareillage compliqué et coûteaux.The present invention aims to overcome all the above constraints by providing a method and an automatic container sealing device which can use lids of any size, which are sterilized on both sides in a way efficient and without the need for complicated and expensive equipment.

A cet effet, l'invention a pour objet un procédé d'operculage de récipients, tels que par exemple des gobelets, et du type consistant à saisir des opercules à l'aide de ventouses solidaires d'un tambour et à relâcher ensuite ces opercules après rotation du tambour, caractérisé en ce qu'après avoir saisi l'opercule, on plaque celui-ci par action du vide contre la paroi du tambour afin que ce dernier puisse chauffer et stériliser par conduction thermique ledit opercule, ce après quoi on applique, après rotation du tambour, le bord du récipient contre l'opercule chauffé et stérilisé avant qu'il soit relâché du tambour de façon à permettre la fixation au moins provisoire de l'opercule chaud et stérile sur le bord du récipient, à la suite de quoi l'opercule est relâché de sa ventouse avec le récipient.To this end, the subject of the invention is a method of sealing containers, such as for example cups, and of the type consisting in gripping lids using suction cups integral with a drum and then releasing these lids after rotation of the drum, characterized in that after having gripped the cover, it is pressed by the action of vacuum against the wall of the drum so that the latter can heat and sterilize by thermal conduction said cover, after which it is applied , after rotation of the drum, the edge of the container against the heated and sterilized cover before it is released from the drum so as to allow at least temporary fixing of the hot and sterile cover on the edge of the container, following whereupon the cover is released from its suction cup with the container.

L'invention vise également un dispositif d'operculage pour la mise en oeuvre du procédé ci-dessus, et du type comprenant un tambour auquel sont associées des ventouses reliées à une source de vide pour pouvoir saisir des opercules, caractérisé par un circuit de vide aménagé dans des facettes constituant la périphérie du tambour, et débouchant au niveau de la face externe de ces facettes, dans lesquelles est noyé un moyen de chauffage tel que par exemple au moins une résistance électrique chauffante.The invention also relates to a sealing device for implementing the above method, and of the type comprising a drum with which suction cups are associated connected to a vacuum source to be able to grasping the lids, characterized by a vacuum circuit arranged in facets constituting the periphery of the drum, and opening at the level of the external face of these facets, in which is embedded a heating means such as for example at least one electric heating resistance .

Suivant une autre caractéristique de ce dispositif, les ventouses sont montées coulissantes dans les facettes orthogonalement au plan de celles-ci, et comportent chacune une face dans laquelle débouche un circuit de vide et affleurant avec la face externe des facettes en position rétractée des ventouses dans le tambour.According to another characteristic of this device, the suction cups are slidably mounted in the facets orthogonally to the plane of these, and each comprise a face in which opens a vacuum circuit and flush with the external face of the facets in the retracted position of the suction cups in the drum.

On précisera encore ici que la face externe des facettes du tambour comporte une partie en creux recevant la tête des ventouses.It will also be specified here that the external face of the facets of the drum has a hollow part receiving the head of the suction cups.

Suivant une autre caractéristique de ce dispositif, les ventouses sont constamment sollicitées par un ressort en position rétractée dans les facettes du tambour et sont commandées par un poussoir à crémaillère engrenant avec un pignon et agencé au centre du tambour.According to another characteristic of this device, the suction cups are constantly stressed by a spring in the retracted position in the facets of the drum and are controlled by a rack pusher meshing with a pinion and arranged in the center of the drum.

Le circuit de vide aménagé dans les facettes du tambour comporte une pluralité de conduits débouchant sur la face externe des facettes autour du logement recevant la ventouse et reliés à un collecteur connecté à une source de vide.The vacuum circuit arranged in the facets of the drum comprises a plurality of conduits opening on the external face of the facets around the housing receiving the suction cup and connected to a collector connected to a source of vacuum.

Ce dispositif peut être avantageusement incorporé dans une machine de conditionnement de récipients comportant notamment un système de remplissage des récipients en amont du tambour, un système de thermoscellage des opercules en aval de ce tambour, et un système de poussée des récipients contre ce tambour et disposé en dessous de celui-ci.This device can advantageously be incorporated in a container packaging machine comprising in particular a system for filling the containers upstream of the drum, a system for sealing the lids downstream of this drum, and a system for pushing the containers against this drum and arranged in below it.

Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit, et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels :

  • La figure 1 est une vue schématique et en élévation d'un dispositif conforme à l'invention et incorporé à une machine de conditionnement de récipients, ce dispositif étant montré en coupe ;
  • La figure 2 est une vue agrandie et en coupe passant par l'axe de la ventouse, de l'une des facettes du tambour ;
  • La figure 3 est une vue identique à la figure 1, mais montrant le tambour après qu'il ait saisi un opercule et effectué une légère rotation ; et
  • La figure 4 est une vue similaire aux figures 1 et 3, mais illustrant l'application d'un récipient contre un opercule retenu par le tambour, après que celui-ci ait effectué une rotation de 180° par rapport au poste de délivrance des opercules.
However, other characteristics and advantages of the invention will appear better in the detailed description which follows, and refers to the appended drawings, given solely by way of example, and in which:
  • Figure 1 is a schematic view in elevation of a device according to the invention and incorporated in a container packaging machine, this device being shown in section;
  • Figure 2 is an enlarged sectional view through the axis of the suction cup, one of the facets of the drum;
  • Figure 3 is a view identical to Figure 1, but showing the drum after it has grasped a cover and made a slight rotation; and
  • Figure 4 is a view similar to Figures 1 and 3, but illustrating the application of a container against a cover retained by the drum, after the latter has made a rotation of 180 ° relative to the station of delivery of the covers .

En se reportant aux figures, on voit en partie une machine de conditionnement automatique de récipients ou gobelets R acheminés par un convoyeur (non représenté) et passant successivement en dessous d'un poste de remplissage 1, d'un poste d'operculage 2 et, éventuellement, d'un poste de thermoscellage 3 des opercules 4 sur les récipients R, lesquels opercules sont par exemple empilés dans une trémie ou analogue 5 située au-dessus du poste 2.Referring to the figures, we see in part an automatic packaging machine for containers or cups R conveyed by a conveyor (not shown) and passing successively below a filling station 1, a sealing station 2 and , optionally, a heat-sealing station 3 for the lids 4 on the containers R, which lids are for example stacked in a hopper or the like 5 situated above the station 2.

Le poste d'operculage 2 est constitué par un dispositif qui fait l'objet de la présente invention et sera décrit en détail ci-après.The sealing station 2 is constituted by a device which is the subject of the present invention and will be described in detail below.

Il comprend un tambour 6 dont la périphérie est constituée par une pluralité de facettes 7 dans chacune desquelles est aménagé un circuit de vide débouchant sur la face externe 7a des facettes 7. En outre, dans chaque facette 7, est noyé un moyen de chauffage constitué par une ou plusieurs résistances électriques chauffantes 8.It comprises a drum 6 whose periphery is constituted by a plurality of facets 7 in each of which is arranged a vacuum circuit opening on the external face 7a of facets 7. In addition, in each facet 7, a heating means is embedded consisting by one or more electric heating resistors 8.

Comme on le voit mieux sur la figure 2, le circuit de vide dans chaque facette 7 est constitué par une pluralité de conduits 9 débouchant au niveau de la face externe 7a des facettes et reliés par l'intermédiaire d'un collecteur 10 à une source de vide qui n'est pas représentée.As best seen in Figure 2, the vacuum circuit in each facet 7 is constituted by a plurality of conduits 9 opening at the level of the external face 7a of the facets and connected via a collector 10 to a source that is not shown.

Dans chaque facette 7, est montée orthogonalement coulissante une ventouse 11 dont la tête 12 peut, en position rétractée de ladite ventouse, être reçue dans une partie en creux ou logement 13 ménagée dans la face externe 7a de la facette 7. Plus précisément et comme on le voit bien sur la figure 2, la face 12a de la tête 12 de la ventouse 11 affleure avec la surface externe 7a de la facette 7 à laquelle la ventouse est associée, lorsque ladite ventouse est en position rétractée dans la facette. Il est à noter ici que les ventouses 11 sont constamment sollicitées en position rétractée grâce à un moyen de rappel, tel que par exemple un ressort 14 interposé entre la face inférieure 15 de la facette et un élément de butée 16 solidaire d'une tige ou analogue 17 constituant la partie arrière de la ventouse 11.In each facet 7, is mounted orthogonally sliding a suction cup 11 whose head 12 can, in the retracted position of said suction cup, be received in a hollow part or housing 13 formed in the external face 7a of the facet 7. More precisely and as as can be seen in FIG. 2, the face 12a of the head 12 of the suction cup 11 is flush with the external surface 7a of the facet 7 with which the suction cup is associated, when said suction cup is in the retracted position in the facet. It should be noted here that the suction cups 11 are constantly stressed in the retracted position by means of a return means, such as for example a spring 14 interposed between the underside 15 of the facet and a stop element 16 secured to a rod or analog 17 constituting the rear part of the suction cup 11.

Chaque ventouse 11 comporte un circuit de vide essentiellement constitué par une ou plusieurs conduites 18 débouchant vers la face externe 12a des têtes 12 de ventouse et reliées à une source de vide (non représentée) par l'intermédiaire, par exemple, d'un collecteur 18a.Each suction cup 11 comprises a vacuum circuit essentially constituted by one or more conduits 18 opening towards the external face 12a of the heads 12 of suction cup and connected to a vacuum source (not shown) via, for example, a collector 18a.

Le déplacement de la ventouse 11par rapport à la facette 7 est, suivant l'exemple de réalisation représenté, commandé par un poussoir à crémaillère 19 montré schématiquement sur la figure 1 et engrenant avec un pignon 20. L'entraînement en rotation de ce pignon par un moyen quelconque permet un déplacement alternatif du poussoir 19 qui agit sur la tige 17 portant la ventouse 11, comme cela est bien visible sur la figure 1.The movement of the suction cup 11 relative to the facet 7 is, according to the embodiment shown, controlled by a rack plunger 19 shown diagrammatically in FIG. 1 and meshing with a pinion 20. The rotation drive of this pinion by any means allows an alternative movement of the pusher 19 which acts on the rod 17 carrying the suction cup 11, as is clearly visible in FIG. 1.

Mais on décrira en détail maintenant le fonctionnement du dispositif d'operculage qui vient d'être décrit en se référant plus particulièrement aux figures 1, 3 et 4.However, the operation of the sealing device which has just been described will now be described in detail with particular reference to FIGS. 1, 3 and 4.

Comme on le voit sur la figure 1, la ventouse 11 est poussée hors du plan de la facette 7 à laquelle elle est associée, grâce au poussoir 19 qui est agencé sensiblement au centre du tambour 6. Ainsi, la tête 12 de la ventouse 11 pourra saisir, par action du vide dans la conduite 18, un opercule 4 dans la trémie 5.As can be seen in FIG. 1, the suction cup 11 is pushed out of the plane of the facet 7 with which it is associated, thanks to the plunger 19 which is arranged substantially in the center of the drum 6. Thus, the head 12 of the suction cup 11 will be able to grasp, by action of the vacuum in the pipe 18, a cover 4 in the hopper 5.

Le poussoir 19 est alors actionné vers le bas, et grâce au ressort de rappel 14, la tête 12 de la ventouse 11 retenant un opercule 4 viendra se loger dans la partie en creux 13 de la facette 7. Dès lors, l'opercule 4 se trouvera dans le même plan que celui de la face externe 7a de la facette 7 et sera intimement plaqué contre cette face externe par action du vide dans les conduits 9.The pusher 19 is then actuated downwards, and thanks to the return spring 14, the head 12 of the suction cup 11 retaining a cover 4 will be housed in the hollow part 13 of the facet 7. Therefore, the cover 4 will be in the same plane as that of the external face 7a of the facet 7 and will be intimately pressed against this external face by action of the vacuum in the conduits 9.

Le tambour 6 pourra alors commencer sa rotation comme on le voit sur la figure 3, étant entendu que, pendant cette rotation, la facette 7 sera chauffée par les résistances électriques 18 noyées dans ladite facette et permettant ainsi le chauffage et la stérilisation par conduction thermique des deux faces de l'opercule 4, à une température voisine de 170° C. On insistera ici sur le fait qu'on obtient, grâce à cette méthode, une stérilisation idéale et parfaite de la totalité de l'opercule qui peut avoir une dimension quelconque en fonction du récipient à obturer, puisqu'il n'y a pas lieu de le maintenir latéralement étant donné qu'il est parfaitement maintenu lors de la rotation du tambour 6 par aspiration contre les facettes de ce tambour.The drum 6 can then start its rotation as seen in Figure 3, it being understood that, during this rotation, the facet 7 will be heated by the electrical resistors 18 embedded in said facet and thus allowing heating and sterilization by thermal conduction on both sides of the cover 4, at a temperature close to 170 ° C. It will be emphasized here that, thanks to this method, an ideal and perfect sterilization of the entire cover is obtained, which may have a any dimension depending on the container to be closed, since there is no need to maintain it laterally since it is perfectly maintained during rotation of the drum 6 by suction against the facets of this drum.

Lorsque le tambour a effectué une rotation de 180° et que la ventouse 11 retenant l'opercule 4 se trouve au droit d'un récipient R à obturer, comme on le voit sur la figure 4, on soulève le récipient R à l'aide d'un système de poussée quelconque 21 pour appliquer ainsi le bord ouvert 22 du récipient R contre l'opercule 4 qui demeure retenu par le vide contre la face externe 7a de la facette.When the drum has rotated 180 ° and the suction cup 11 retaining the cover 4 is located in the right of a container R to be closed, as seen in Figure 4, the container R is raised using any pushing system 21 to thereby apply the open edge 22 of the container R against the cover 4 which remains retained by the vacuum against the outer face 7a of the facet.

Ainsi, comme on le comprend, l'opercule 4 stérile et chaud va se fixer, à la manière d'un collage, sur le bord 22 du récipient R, ce après quoi, on casse le vide dans les conduits 18 et 9, de sorte que l'opercule 4 est relâché du tambour, étant entendu que le système de poussée 21 fait descendre le récipient R qui peut ensuite parvenir au poste de termoscellage 3 de façon à parfaire l'obturation.Thus, as is understood, the sterile and hot cover 4 will be fixed, in the manner of a bonding, on the edge 22 of the container R, after which the vacuum is broken in the conduits 18 and 9, so that the cover 4 is released from the drum, it being understood that the pushing system 21 lowers the container R which can then reach the heat-sealing station 3 so as to perfect the obturation.

Mais il est à noter ici que le thermoscellage n'est nullement obligatoire à partir du moment où, comme on l'a décrit précédemment, une fixation relativement solide de l'opercule 4 sur le bord 22 du récipient R peut être déjà obtenue au niveau du poste d'operculage 2.However, it should be noted here that heat sealing is in no way compulsory from the moment when, as described above, a relatively solid fixing of the cover 4 on the edge 22 of the container R can already be obtained at the level the sealing station 2.

On a montré schématiquement en 23 sur les figures 1, 3 et 4 une grille ou analogue permettant éventuellement une distribution d'air stérile en regard du tambour 6 et en amont de ce tambour pour maintenir les récipients R remplis et non obturés, en atmosphère stérile, mais un tel moyen n'est nullement obligatoire et pourrait parfaitement être omis sans sortir du cadre de l'invention.There is shown diagrammatically at 23 in FIGS. 1, 3 and 4 a grid or the like possibly allowing a distribution of sterile air opposite the drum 6 and upstream of this drum to keep the containers R filled and not closed, in a sterile atmosphere. , but such a means is in no way mandatory and could perfectly well be omitted without departing from the scope of the invention.

On a donc réalisé suivant l'invention un dispositif d'operculage qui permet la préhension et la stérilisation parfaites d'opercules de dimensions quelconques, ce dispositif pouvant même permettre l'obturation de récipients ou gobelets sans moyens de centrage particulier et sans qu'une opération particulière et supplémentaire de thermoscellage soit absolument nécessaire.We therefore produced according to the invention a sealing device which allows the perfect gripping and sterilization of lids of any size, this device can even allow the closure of containers or cups without special centering means and without a special and additional heat sealing operation is absolutely necessary.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

C'est ainsi que les moyens 21 de poussée du récipient R contre les facettes du tambour peuvent revêtir une forme quelconque, et que ce tambour peut être incorporé dans une machine quelconque de récipients à remplir avec un produit également quelconque.Thus the means 21 for pushing the container R against the facets of the drum can take any shape, and this drum can be incorporated in any machine of containers to be filled with an equally arbitrary product.

L'invention comprend donc tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.The invention therefore includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
