Description
L'invention concerne un procédé destiné à finaliser un emballage, cette finalisation consistant essentiellement dans la réalisation d'une ouverture au sein de ces emballages et de la mise en place d'un dispositif d'ouverture et de fermeture sur ledit emballage.The invention relates to a method for finalizing packaging, this finalization consisting essentially in the realization of a opening within these packages and the installation of a device opening and closing on said packaging.
Dans le domaine de l'emballage, notamment de produits liquides, le recours au carton ou aux matériaux composites mettant en oeuvre le carton a fait l'objet de nombreux développements.In the field of packaging, in particular of liquid products, the use of cardboard or composite materials using the cardboard has been the subject of numerous developments.
De nombreux emballages de ce type se présentent notamment sous la forme de briques, et s'avèrent tout particulièrement recherchés, dès lors que se pose le problème de leur transport, leur stockage et corollairement leur gerbage.Many packages of this type are found in particular under the brick form, and are particularly sought after, therefore that there is the problem of their transport, their storage and as a corollary their stacking.
Dans l'optique du gerbage possible de tels emballages, de nombreux types de système d'ouverture et de fermeture ont été proposés. Dans tous les cas de figure, les systèmes d'ouverture et de fermeture proposés supposent la réalisation d'une prédécoupe au sein de l'emballage, et notamment de sa face supérieure, de telle sorte que, lors de la première utilisation de l'emballage, c'est à dire lors de sa première ouverture, l'utilisateur puisse aisément ouvrir à proprement parlé ledit emballage pour ainsi libérer l'accès à l'intérieur de l'emballage, et corollairement de permettre au liquide qu'il contient d'être déversé.In view of the possible stacking of such packages, many types of opening and closing systems have been proposed. In all the scenarios, the opening and closing systems proposed presuppose a precut within the packaging, and especially from its upper face, so that, during the first use of the packaging, i.e. when it is first opened, the user can easily open the package itself to thus free access to the interior of the packaging, and as a corollary of allow the liquid it contains to be spilled.
Par ailleurs, dans un souci d'optimiser les cadences de production de ces emballages, ces prédécoupes sont effectuées directement sur le matériau constitutif de l'emballage se présentant sous forme de laize, c'est à dire en amont de la réalisation proprement dite de l'emballage. In addition, in order to optimize the production rates of these packaging, these pre-cuts are made directly on the constituent material of the packaging in the form of a web, that is to say upstream of the actual production of the packaging.
A cet effet, différents dispositifs et procédés ont été proposés pour réaliser de telles prédécoupes sur les laizes, tel que notamment le document EP-A-0 357 841 ou EP-A-0 398 447. De tels procédés de prédécoupe font appel à la technologie laser et sont munis de capteurs destinés à permettre la reconnaissance d'un motif imprimé de manière répétitive, afin de localiser de manière très précise la réalisation de la prédécoupe.To this end, various devices and methods have been proposed for make such pre-cuts on the widths, such as in particular the document EP-A-0 357 841 or EP-A-0 398 447. Such methods of pre-cut use laser technology and are fitted with sensors intended to allow the recognition of a printed pattern so repetitive, in order to locate very precisely the realization of the pre-cut.
Parmi ces différents types d'emballages à base de matériaux composites, notamment d'un complexe carton - aluminium - matière plastique et plus particulièrement film polyéthylène, on a également développé des procédés et dispositifs susceptibles de réaliser des emballages aseptiques.Among these different types of packaging based on materials composites, in particular of a cardboard - aluminum - material complex plastic and more particularly polyethylene film, we also have developed processes and devices capable of producing packaging aseptic.
L'une des étapes de ce procédé consiste à soumettre la laize du matériau à une phase de stérilisation par passage dans un bain de peroxyde d'hydrogène (eau oxygénée), préalablement à une étape de séchage.One of the steps in this process is to submit the width of the material in a sterilization phase by passage through a bath of hydrogen peroxide (hydrogen peroxide), prior to a drying step.
Ledit matériau est ensuite conformé sous la forme d'un tube continu et subit un remplissage permanent du liquide qu'il est destiné à contenir avant d'être découpé sous forme d'emballage unitaire. Cette technique est par exemple décrite dans le document FR-A-2 195 550. En d'autres termes, l'introduction du liquide dans l'emballage se fait dans des conditions parfaitement stériles.Said material is then shaped into a tube continuous and undergoes a permanent filling of the liquid which it is intended for contain before being cut into unit packages. This technique is for example described in the document FR-A-2 195 550. In in other words, the introduction of the liquid into the packaging takes place in perfectly sterile conditions.
Un tel procédé se retrouve également dans le document US-A-4 990 200, la phase de stérilisation n'y étant cependant pas décrite. Le préambule de la revendication est basé sur cet état de la technique.Such a process is also found in document US-A-4,990,200, the sterilization phase however not being described there. The preamble to the claim is based on this state of the art.
En revanche, un tel procédé de remplissage suppose la réalisation de prédécoupes préalablement à cette phase de stérilisation. Or, compte-tenu de la réalisation de ces prédécoupes au sein du matériau constitutif de l'emballage, le carton, pris en sandwich dans le matériau composite constitutif du matériau proprement dit entre en contact avec l'eau oxygénée au niveau de ces zones de prédécoupes, entraínant ainsi un risque de contamination.On the other hand, such a filling process supposes the realization of pre-cuts prior to this sterilization phase. Gold, taking into account the realization of these precuts within the material constituting the packaging, the cardboard, sandwiched in the composite material component of the material itself comes into contact with water oxygenated in these pre-cut areas, thus causing risk of contamination.
Une alternative pour pallier cet inconvénient a été proposée, qui consiste à mettre en place de part et d'autre de la prédécoupe un film de protection local, réalisé en polyéthylène ou en un complexe aluminium - film adhésif, les deux films de protection ainsi constitués étant enlevés lors de la première ouverture de l'emballage. Si certes, la mise en place de ce film permet de s'affranchir de tout risque de contamination de la zone d'ouverture par l'eau oxygénée, en revanche, elle implique une étape supplémentaire dans le processus de réalisation de l'emballage, et induit l'application de deux adhésifs au niveau de la zone de pré-découpe, cette étape s'avérant relativement difficile à mettre au point, compte tenu de la précision nécessaire à la localisation de l'adhésif, et consommatrice de temps, altérant au final de manière significative le coût de production de tels emballages.An alternative to overcome this drawback has been proposed, which consists in putting in place on both sides of the precut a film of local protection, made of polyethylene or an aluminum complex - adhesive film, the two protective films thus formed being removed when the packaging is opened for the first time. If indeed, the establishment of this film eliminates any risk of contamination of the area opening with hydrogen peroxide, on the other hand, it involves a step additional in the packaging production process, and induced the application of two adhesives at the pre-cutting area, this step that is relatively difficult to develop, given the precision required to locate the adhesive, and consumes time, significantly altering the production cost of such packaging.
L'objet de l'invention est de s'affranchir de ces différents inconvénients.The object of the invention is to get rid of these different disadvantages.
Elle propose un procédé pour la mise en place d'un dispositif d'ouverture et de fermeture d'un emballage du type en question, qui consiste tout d'abord à remplir ledit emballage, puis, à subir l'opération de prédécoupe, par exemple par laser, de telle sorte à définir une zone de moindre résistance notamment sur sa face supérieure, et enfin à recevoir au niveau de cette zone un bouchon ou système d'ouverture collé sur la périphérie de ladite zone de moindre résistance.It proposes a method for setting up a device opening and closing of a package of the type in question, which consists first of all in filling said packaging, then in undergoing the operation pre-cut, for example by laser, so as to define a zone of less resistance especially on its upper side, and finally to receive in this area a plug or opening system stuck on the periphery of said zone of least resistance.
En d'autres termes, l'invention consiste à réaliser l'opération de prédécoupe non pas sur le matériau sous forme de laize, destiné à devenir emballage, mais sur l'emballage proprement dit déjà réalisé et déjà rempli. In other words, the invention consists in carrying out the operation of pre-cut not on the material in the form of a web, intended for become packaging, but on the packaging itself already produced and already filled.
De la sorte, on s'affranchit de cette manière de tout risque de contamination du matériau constitutif de l'emballage au niveau des zones de prédécoupe, puisque le matériau soumis à l'opération de stérilisation en milieu péroxyde est un matériau sain n'ayant encore subi aucune altération, y compris par voie de prédécoupe.In this way, we are freed in this way from any risk of contamination of the material of the packaging at the level of precut areas, since the material subjected to the operation of sterilization in peroxide medium is a healthy material which has not yet undergone no alteration, including by precut.
Avantageusement, l'opération de prédécoupe et de mise en place du bouchon s'effectuent au même poste, au niveau duquel l'emballage rempli est maintenu par un système d'indexage.Advantageously, the operation of pre-cutting and placing the plug are made at the same station, at which the packaging filled is maintained by an indexing system.
Cependant, on peut également envisager la non mise en oeuvre d'un tel système d'indexage, la localisation de la zone de prédécoupe étant reperée par des cellules photoélectriques.However, one can also consider the non-implementation of such an indexing system, the location of the precut area being spotted by photoelectric cells.
La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit donné à titre indicatif et non limitatif à l'appui des figures annexées.The manner in which the invention can be realized and the advantages which will emerge more clearly from the example of embodiment which follows given as an indication and not limiting in support of the appended figures.
La figure 1 est une représentation schématique en perspective du procédé conforme à l'invention.Figure 1 is a schematic perspective representation of the process according to the invention.
La figure 2 est une représentation schématique d'un emballage en sortie de remplisseuse, respectivement 2a, après prédécoupe 2b, et après mise en place d'un bouchon 2c.Figure 2 is a schematic representation of a packaging in filler outlet, respectively 2a, after precut 2b, and after fitting a plug 2c.
On a représenté schématiquement une installation susceptible de mettre en oeuvre le procédé conforme à l'invention.An installation capable of implement the method according to the invention.
Cette installation comprend fondamentalement une remplisseuse (1), symbolisée par un parallélépipède et, qui est en fait une machine relativement complexe, abondamment décrite dans la littérature (voir par exemple FR-A-2 195 550), et qui ne constitue pas l'objet de la présente invention. This installation basically includes a filler (1), symbolized by a parallelepiped and, which is in fact a machine relatively complex, abundantly described in the literature (see for example FR-A-2 195 550), and which is not the subject of this invention.
A l'issue de cette remplisseuse, c'est à dire le lieu au niveau duquel les emballages (4), ainsi que déjà précisé, sont remplis préalablement à leur formation et découpe et pliage, lesdits emballages (4) sortent de manière unitaire sur un convoyeur (9), destiné à les acheminer au niveau d'un poste de prédécoupe (2). Ce poste de prédécoupe comporte un laser (5), notamment un laser CO2, destiné à réaliser sur la face supérieure (6) des emballages (4) une zone de prédécoupe (7), par exemple de forme elliptique telle que représentée sur les figures 1 et 2b. Les emballages arrivant au poste de pré-découpe (2) étant maintenus fixes, le laser est lui-même fixe. On peut néanmoins concevoir un poste de prédécoupe au niveau duquel, le laser accompagne à la même vitesse l'emballage, poursuivant lui-même sa progression au moyen du convoyeur (9), ledit laser étant animé d'un mouvement de retour, dès que la prédécoupe est réalisée.At the end of this filler, that is to say the place at which the packages (4), as already specified, are filled before their formation and cutting and folding, said packages (4) come out unitarily on a conveyor (9), intended to convey them to a precut station (2). This precut station includes a laser (5), in particular a CO 2 laser, intended to produce on the upper face (6) of the packages (4) a precut area (7), for example of elliptical shape as shown in the Figures 1 and 2b. Since the packages arriving at the pre-cutting station (2) are kept fixed, the laser is itself fixed. It is nevertheless possible to design a precut station at which the laser accompanies the packaging at the same speed, itself continuing its progression by means of the conveyor (9), said laser being driven by a return movement, as soon as the precut is carried out.
Typiquement, le rayon laser est réglé de telle sorte que la prédécoupe ne traverse pas l'intégralité du matériau composite constitutif de l'emballage, mais conserve à tout le moins l'intégrité du revêtement interne de l'emballage, de telle sorte à conférer à celui-ci l'étanchéité vis à vis de la lumière et de l'air ambiant, et partant son asepsie.Typically, the laser beam is adjusted so that the precut does not pass through the entire composite material of packaging, but at the very least retains the integrity of the coating internal of the packaging, so as to give it sealing against saw the light and the ambient air, and therefore his asepsis.
Les emballages ainsi pourvus de leur prédécoupe (7), sont alors acheminés au moyen d'un même convoyeur ou d'un autre convoyeur au niveau du poste de mise en place (3) des bouchons de fermeture et d'ouverture (8).The packages thus provided with their precut (7) are then conveyed by the same conveyor or another conveyor at the installation station (3) closure caps and opening (8).
Cette mise en place des bouchons est avantageusement totalement automatisée, lesdits bouchons étant en fait collés au niveau de la périphérie de la zone de prédécoupe. This placement of the plugs is advantageously totally automated, said plugs being in fact glued to the level of the periphery of the precut area.
Par ailleurs, il peut être envisagé d'effectuer les opérations de prédécoupe et de mise en place des bouchons au sein du même poste. Avantageusement, les emballages au niveau de chacun de ces postes sont maintenus en place et positionnés correctement au moyen de système d'indexage (non représentés) permettant ainsi d'aboutir à une très grande précision d'une part, dans la réalisation de la zone de prédécoupe et d'autre part, dans la mise en place des bouchons ou systèmes d'ouverture et de fermeture (8).Furthermore, it may be envisaged to carry out the operations of precut and placement of caps within the same station. Advantageously, the packaging at each of these stations is held in place and positioned correctly by system indexing (not shown) thus allowing to achieve a very large precision on the one hand, in the realization of the precut area and on the other hand, in the installation of caps or opening systems and closing (8).
L'intégralité du processus de prédécoupe et de mise en place du bouchon est ainsi automatisée, permettant de conserver les cadences de production des emballages déjà connues et obtenus par les machines de remplissage, sans pour autant altérer les conditions d'asepsie de réalisation des matériaux, et partant de l'emballage. Par ailleurs, le laser mis en oeuvre au niveau du poste de prédécoupe (2) est un laser standard (CO2) ne nécessitant donc pas un investissement conséquent.The entire process of pre-cutting and fitting the cap is thus automated, making it possible to maintain the production rates of the packaging already known and obtained by the filling machines, without altering the aseptic conditions for making the materials. , and starting from the packaging. Furthermore, the laser used at the precut station (2) is a standard laser (CO 2 ) therefore not requiring a substantial investment.
On concoit donc tout l'intérêt d'un tel procédé, permettant de manière très simple de s'affranchir des risques inhérents à l'opération de stérilisation en bain péroxyde.We therefore understand the value of such a process, allowing very simple way to get rid of the risks inherent in the operation of sterilization in peroxide bath.
