Description

Machine et Procédé de fabrication d’un conditionnementMachine and process for manufacturing packaging

La présente invention concerne le domaine des conditionnements. Elle trouve pour application particulièrement avantageuse le domaine des machines et des procédés de fabrication de conditionnements.The present invention relates to the field of packaging. It finds a particularly advantageous application in the field of packaging manufacturing machines and processes.

ETAT DE LA TECHNIQUESTATE OF THE ART

Il existe plusieurs types de conditionnement. Chaque type de conditionnement nécessite généralement son propre procédé de fabrication. Il en découle généralement la nécessité de créer une machine propre audit procédé.There are several types of conditioning. Each type of packaging generally requires its own manufacturing process. This generally results in the need to create a machine specific to said process.

Une des principales problématiques rencontrées dans le domaine du conditionnement repose sur l’optimisation d’une série d’étapes, optimisation du procédé en tant que tel autant que de la ou des machines nécessaires pour la conception du conditionnement.One of the main problems encountered in the field of packaging is based on the optimization of a series of steps, optimization of the process as such as much as of the machine(s) necessary for the design of the packaging.

Par exemple, de plus en plus de procédés de fabrication de conditionnements font appel à diverses machines parfois même délocalisées les unes des autres pour des questions de coût. Cette démarche n’est ni la plus optimisée qui soit ni la plus écologique.For example, more and more packaging manufacturing processes use various machines, sometimes even relocated from each other for cost reasons. This approach is neither the most optimized nor the most ecological.

Un objet de la présente invention est donc de proposer une solution à l’une au moins de ces diverses problématiques.An object of the present invention is therefore to propose a solution to at least one of these various problems.

Les autres objets, caractéristiques et avantages de la présente invention apparaîtront à l'examen de la description suivante et des dessins d'accompagnement. Il est entendu que d'autres avantages peuvent être incorporés.The other objects, features and advantages of the present invention will become apparent from a review of the following description and the accompanying drawings. It is understood that other benefits may be incorporated.

RESUMESUMMARY

Pour atteindre cet objectif, selon un mode de réalisation, on prévoit une machine de fabrication, de préférence automatisée, d’un conditionnement comprenant une poche destinée à contenir un produit et à en permettre la restitution, ledit conditionnement comprenant une enveloppe formant un tronc, une embase et un dispositif de fermeture disposé à une extrémité du tronc, la machine comprenant, de préférence successivement, au moins :

To achieve this objective, according to one embodiment, a machine is provided for the manufacture, preferably automated, of packaging comprising a pocket intended to contain a product and to allow it to be returned, said packaging comprising an envelope forming a trunk, a base and a closure device arranged at one end of the trunk, the machine comprising, preferably successively, at least:
  • a station for forming and sealing a trunk from a pattern based on a first film, said station comprising a winding support configured to be at least partially surrounded by the pattern so as to allow shaping of the trunk, the trunk extending along a main axis of extension from a first end to a second end, the trunk having in section, along a plane perpendicular to the main axis of extension, a section which narrows from the second end to the first end, said station comprises a heating device capable of heating the inner surface and the outer surface of the envelope forming the trunk so as to allow the sealing of said trunk, preferably skin against flesh,
  • a first station for sealing an end piece with the trunk intended to at least partially form the closure device, the first sealing station comprising at least one additional heating device, configured to allow the sealing by heating of a perimeter of the first end of the trunk in contact with a portion of the tip
  • a first station for sealing a base with the trunk so as to form a sealed periphery, the first sealing station comprising at least one second additional heating device configured to allow the sealing by heating of a periphery of the second end of the trunk in contact with a portion of a circumference of the base, the base being at least partly located inside the trunk;

La présente invention permet préférentiellement de calibrer avec précision la hauteur du pourtour scellé du conditionnement, c’est en partie au moins ce pourtour et sa calibration qui permettent au conditionnement de tenir droit en reposant sur ledit pourtour scellé.The present invention preferably makes it possible to precisely calibrate the height of the sealed perimeter of the packaging, it is at least partly this perimeter and its calibration which allow the packaging to stand upright while resting on said sealed perimeter.

De plus, la machine de la présente invention permet un alignement à fleur de l’embase et du tronc ce qui permet une intégration précise de l’embase.In addition, the machine of the present invention allows a flush alignment of the base and the trunk which allows precise integration of the base.

Sans la présente invention il faudrait prévoir des étapes supplémentaires qui nécessairement engendreraient des coûts additionnels en énergie et en matériaux.Without the present invention, additional steps would have to be provided which would necessarily generate additional costs in terms of energy and materials.

Ainsi, la présente invention permet de limiter les coûts de production d’un contenant souple et plus particulièrement d’un conditionnement comprenant une poche déformable, cette poche étant produite à partir d’un film suffisamment souple pour ployer sous l’action de son propre poids.Thus, the present invention makes it possible to limit the production costs of a flexible container and more particularly of a packaging comprising a deformable pocket, this pocket being produced from a film sufficiently flexible to bend under the action of its own weight.

La présente invention permet de fabriquer un conditionnement à la fois aisément déformable mais également apte à se supporter lui-même, c’est-à-dire pouvant être autoportant dans une configuration où par exemple le conditionnement est disposé à la verticale c’est-à-dire, lorsque le dispositif de fermeture comme par exemple l’embout, est disposé vers le haut.The present invention makes it possible to manufacture packaging that is both easily deformable but also able to support itself, that is to say which can be self-supporting in a configuration where, for example, the packaging is arranged vertically, i.e. that is to say, when the closing device such as for example the end piece, is arranged upwards.

La présente invention permet en outre une maintenance aisée puisque chaque poste peut être décorrélé des autres et ainsi facilement remplacé.The present invention also allows easy maintenance since each station can be decorrelated from the others and thus easily replaced.

Selon un mode de réalisation, l’invention comprend un procédé de fabrication d’un conditionnement comprenant une poche destinée à contenir un produit et à en permettre la restitution, ledit conditionnement comprenant une enveloppe formant un tronc, une embase et un dispositif de fermeture disposé à une extrémité du tronc, la machine comprenant au moins les étapes suivantes :

  • formation d’un tronc à partir d’un patron à base d’un premier film, ledit poste comprenant un support d’enroulement configuré pour être entouré au moins partiellement du patron de sorte à permettre la mise en forme du tronc, le tronc s’étendant selon un axe d’extension principal depuis une première extrémité jusqu’à une deuxième extrémité, le tronc présentant en coupe, selon un plan perpendiculaire à l’axe d’extension principal, une section qui se rétrécit depuis la deuxième extrémité jusqu’à la première extrémité,
  • scellage dudit tronc, de préférence peau contre chair, avantageusement à l’aide d’un dispositif de chauffage, apte à chauffer la surface intérieure et la surface extérieure de l’enveloppe formant le tronc
  • premier scellage d’un embout avec le tronc destiné à former en partie au moins le dispositif de fermeture, le premier scellage étant réalisé par application d’un dispositif de chauffage additionnel sur un pourtour de la première extrémité du tronc en contact avec une portion de l’embout
