Description

La présente invention concerne une installation pour la fabrication de dosettes individuelles. Elle concerne également un procédé apte à être mis en oeuvre par cette installation.The present invention relates to an installation for manufacture of individual pods. It also concerns a method capable of being implemented by this installation.

L'invention s'applique à la fabrication de dosettes individuelles du type renfermant entre deux feuilles de papier filtre une dose de produit à infuser.The invention applies to the manufacture of pods individual of the type enclosing between two sheets of paper filters a dose of product to be infused.

Le produit à infuser peut dans un cas préférentiel être du café moulu ou tout autre produit tel que du thé.The product to be infused can in a preferential case be ground coffee or any other product such as tea.

L'invention ici présentée pourra permettre de fabriquer des dosettes telles que décrites dans la demande de brevet antérieure du demandeur WO9507041. Cependant, cette application à des dosettes particulières n'est pas limitative.The invention presented here could make it possible to manufacture pods as described in the patent application Applicant WO9507041. However, this app to particular pods is not limiting.

On connaít déjà diverses installations permettant la fabrication de dosettes individuelles. We already know various facilities for the manufacture of individual pods.

Dans ce cadre, le document EP-A-225494 décrit un appareil pour remplir des pochettes sur un ruban de papier filtre inférieur d'une mesure d'une substance dont doit être faite une infusion, ces pochettes étant recouvertes d'un ruban de papier filtre supérieur et étant ensuite scellées pour former des sachets contenant la substance, en formant ainsi une bande continue de sachets. Cet appareil comporte une table de support stationnaire sur laquelle avance, par étapes, une série de dispositifs en forme de cuvettes peu profondes formés chacun d'une plaque essentiellement quadrangulaire comportant une dépression centrale avec des bords arrondis, le fond de la dépression comportant des trous par lesquels un vide peut être appliqué.In this context, document EP-A-225494 describes an apparatus to fill pockets on a filter paper tape lower of a measurement of a substance from which a infusion, these pouches being covered with a paper tape upper filter and then being sealed to form sachets containing the substance, thereby forming a band continuous sachets. This appliance has a support table stationary on which a series of shallow bowl-shaped devices each formed of an essentially quadrangular plate comprising a central depression with rounded edges, the bottom of the depression with holes through which a vacuum can be applied.

L'appareil présenté dans ce document s'attache surtout à améliorer le déplacement des dosettes individuelles au cours de leur fabrication et propose pour ce faire un système en chaíne de formation de cuvettes sur la feuille de papier filtre inférieure. Cependant, l'appareil présenté selon cette antériorité propose un système de dosage et de mise en place de la dose de café moulu peu avantageux.The device presented in this document focuses especially on improve the movement of individual pods during their manufacture and offers to do this a chain system bowl formation on the filter paper sheet lower. However, the device presented according to this prior art offers a dosing and placement system for the dose of ground coffee not very advantageous.

En effet, un nombre insuffisant de doses peut être réalisé de façon simultanée ce qui nuit à la productivité de l'installation.Indeed, an insufficient number of doses can be achieved simultaneously which affects the productivity of installation.

On connaít par ailleurs du document EP-A-0773160 un appareil de fabrication de sachets de poudre de café moulu comprenant une surface support fixe sur laquelle une chaíne d'alimentation comportant une pluralité de dispositifs plats en forme de coupelle avance de manière intermittente, chacun desdits dispositifs étant formé par une plaque sensiblement quadrangulaire ayant une cavité centrale avec des bords arrondis. Cet appareil comprend un ou plusieurs conteneurs fixes de dosages ayant un fond doté d'une paire de trous traversants d'un diamètre correspondant à la quantité volumétrique de poudre de café devant être fournie sur la ou les bandes inférieures de papier de manière à former une dose destinée à un sachet, un premier disque de distribution tournant de façon intermittente et doté d'une pluralité de paires de trous espacés angulairement de manière que pour chaque déplacement en rotation angulaire, une paire de trous soit disposée en alignement vertical vis à vis de ladite paire de trous ménagée dans le fond dudit conteneur de dosage.We also know from document EP-A-0773160 a apparatus for making sachets of ground coffee powder comprising a fixed support surface on which a chain supply comprising a plurality of flat devices in cup shape intermittently advances, each of said devices being formed by a plate substantially quadrangular having a central cavity with edges rounded. This device includes one or more containers dosing fixtures having a bottom provided with a pair of holes through with a diameter corresponding to the quantity volumetric amount of coffee powder to be supplied on the or the lower strips of paper so as to form a dose intended for a sachet, a first distribution disc intermittently rotating and provided with a plurality of pairs of angularly spaced holes so that for each displacement in angular rotation, a pair of holes is arranged in vertical alignment with respect to said pair holes made in the bottom of said metering container.

Pour permettre un dosage amélioré, cet appareil propose un plateau rotatif de dosage et de dépôt de la dose dans la cuvette formée sur la feuille de papier filtre inférieure. Cependant, selon ce système, seules deux doses de café peuvent être déposées simultanément.To allow an improved dosage, this device offers a rotary plate for dosing and depositing the dose in the bowl formed on the bottom sheet of filter paper. However, under this system, only two doses of coffee can be filed simultaneously.

Encore une fois, une limitation importante de la productivité s'ensuit.Again, a significant limitation of the productivity ensues.

Le document WO-A-92 20579 montre un dispositif de délivrance d'une dose de camomille pour son conditionnement en sachet. Il divulgue un plateau mobile dans lequel un trou permet la réception d'une dose déterminée, puis son évacuation à un autre poste. Document WO-A-92 20579 shows a device for delivering a dose of chamomile for its packaging in sachets. It discloses a mobile tray in which a hole allows the reception of a determined dose, then its evacuation to another station .

Ce système de plateau séquentiel est mu en translation indépendamment d'un piston d'éjection ce qui complique considérablement la synchronisation du dispositif.This sequential plateau system is moved in translation independently of an ejection piston which complicates considerably synchronization of the device.

Par ailleurs, le dispositif s'applique spécifiquement à de la camomille en fleurs pour laquelle les problèmes liés aux matières pulvérulentes (tel du café moulu) ne sont pas présents : fuites du produit, compressibilité limitée notamment.Furthermore, the device applies specifically to flowering chamomile for which problems related to powdery materials (such as ground coffee) are not present: product leaks, limited compressibility especially.

Le type d'emballage à réaliser est, en outre différent compte tenu des procédés différents d'extraction des arômes (infusion et non lixiviation forcée).The type of packaging to be produced is also different. taking into account the different aroma extraction processes (infusion and not forced leaching).

La présente invention a pour but de pallier les inconvénients des systèmes actuels. The object of the present invention is to overcome the disadvantages of current systems.

Elle propose pour ce faire une installation et un procédé de fabrication de dosettes individuelles particulièrement avantageux.To do this, it offers an installation and a process manufacturing of individual pods particularly advantageous.

L'invention comprend en effet de nombreux perfectionnements améliorant la qualité et la productivité dans la fabrication des dosettes.The invention indeed includes numerous improvements improving quality and productivity in manufacturing pods.

L'un des premiers buts de l'invention est d'autoriser une production massive de dosettes par des installations fabriquant de façon parallèle plusieurs dosettes à la fois. Pour y parvenir, l'installation a l'avantage de comporter des moyens aptes à doser plusieurs doses et à les déposer simultanément, en ligne, sur la feuille de papier filtre inférieure avec une fiabilité accrue, par une synchronisation sûre des parties mobiles.One of the first objects of the invention is to authorize a massive production of pods by manufacturing facilities in parallel several pods at the same time. For the installation has the advantage of having means able to dose several doses and deposit them simultaneously, online, on the bottom filter paper sheet with a increased reliability through secure synchronization of parts mobile.

Un autre but de l'invention est d'améliorer les étapes de tassage et de remplissage de la dosette. En effet, elle permet de maintenir un poids constant de la dose de café moulu intégrée dans la dosette.Another object of the invention is to improve the stages of tamping and filling the pod. Indeed, it allows maintain a constant weight of the dose of ground coffee integrated in the pod.

Un autre objet de l'invention est d'éviter tout risque de déchirement des feuilles de papier filtre entourant le produit à infuser et ce par le biais d'une liberté de mouvement et de déformation des feuilles de papier filtre avant l'assemblage.Another object of the invention is to avoid any risk of tearing of the sheets of filter paper surrounding the product to infuse and this through freedom of movement and deformation of the filter paper sheets before assembly.

De plus, l'invention permet de fabriquer des dosettes possédant une grande rigidité par l'intercalement d'un renfort sur le pourtour de la dosette.In addition, the invention makes it possible to manufacture pods having great rigidity by the interposition of a reinforcement around the perimeter of the pod.

L'intercalement d'une bande de renfort entre les deux feuilles de papier filtre permet également de faire participer cet élément de rigidité pour obtenir un bon déplacement et un bon positionnement des dosettes au cours de leur fabrication.The intercalation of a reinforcement strip between the two sheets of filter paper also helps involve this element of rigidity to obtain a good displacement and a good positioning of the pods during their manufacture.

L'invention permet également d'assurer la conservation du café ou d'un autre produit dans les meilleures conditions en évacuant après formation de la dosette tout l'oxygène présent dans la dose de produit à infuser. The invention also makes it possible to ensure the conservation of the coffee or another product under the best conditions evacuating after formation of the pod all the oxygen present in the dose of product to be infused.

    La figure 8 illustre le mouvement de translation du tiroir et un mode préféré pour cet actionnement.Figure 8 illustrates the translational movement of the drawer and a preferred mode for this actuation.

    La figure 9 est une vue partielle de côté.Figure 9 is a partial side view.

    Une dosette individuelle, par exemple remplie d'une dose de café moulu, comprend généralement deux feuilles de papier filtre l'une inférieure l'autre supérieure, renfermant le produit à infuser.An individual pod, for example filled with a dose of ground coffee, usually includes two sheets of paper filters one lower the other upper, containing the product to infuse.

    Les dosettes sont formées à partir de feuilles, généralement des bandes se déroulant au fur et à mesure de la fabrication.The pods are formed from sheets, usually bands unfolding as the manufacturing.

    Dans ce sens, la figure 1 présente la formation de dosettes 1 comportant en leur sein une dose 4 de produit à infuser 5. Cette dose 4 est elle-même enfermée entre deux feuilles de papier filtre, l'une inférieure 2 et l'autre supérieure 3, telles que représentée en figure 2.In this sense, Figure 1 shows the formation of pods 1 comprising within them a dose 4 of product to be infused 5. This dose 4 is itself enclosed between two sheets of filter paper, one lower 2 and the other upper 3, as shown in Figure 2.

    Comme il sera décrit plus loin en détail, un élément de renfort peut permettre d'augmenter la rigidité de la circonférence de la dosette individuelle 1. La présence d'une telle bande de renfort 24 est illustrée également en figure 2.As will be described later in detail, an element of reinforcement can increase the rigidity of the circumference of the individual pod 1. The presence of a such reinforcement strip 24 is also illustrated in FIG. 2.

    Généralement, une installation pour la fabrication de dosette 1 comprend des moyens 6 d'amenée des feuilles 2 et 3.Generally, an installation for the manufacture of pod 1 comprises means 6 for feeding sheets 2 and 3.

    Comme l'illustre la figure 3, ces moyens 6 pourront être un ensemble de rouleaux aptes à stocker et à dérouler les feuilles de papier filtre 2, 3 en bande.As illustrated in FIG. 3, these means 6 could be a set of rollers able to store and unroll sheets of filter paper 2, 3 in a strip.

    Après son déroulement, la feuille de papier filtre inférieure 2 subit une déformation afin de constituer des cuvettes 9 sur sa surface, lesdites cuvettes 9 permettant la réception d'une dose 4 du produit à infuser 5.After its unwinding, the sheet of filter paper lower 2 undergoes a deformation in order to constitute bowls 9 on its surface, said bowls 9 allowing the reception of a dose 4 of the product to be infused 5.

    Des moyens de support et de formation de cuvettes tels que présenté aux figures. Le plaquage de la feuille de papier filtre inférieure 2, par une action mécanique ou pneumatique, sur une surface de mise en forme peut être mis en oeuvre dans ce cadre selon tout procédé courant.Support and bowl-forming means such as presented in the figures. Plating the sheet of paper lower filter 2, by mechanical or pneumatic action, on a shaping surface can be implemented in this frame using any standard process.

    Pour assurer le transfert au cours de la fabrication des dosettes 1 en cours de formation, l'installation comprend également des moyens de déplacement.To ensure the transfer during the manufacture of pods 1 during training, the installation includes also means of movement.

    Comme présenté en figure 3, ces moyens de déplacement peuvent comprendre une bande roulante 21 permettant l'enchaínement de plots 7 aptes à recevoir les cuvettes 9 par le biais d'une cavité 8. La chaíne de plots 7 ainsi formée permet l'avancée progressive des dosettes 1 au cours de leur fabrication.As shown in Figure 3, these means of movement may include a tread 21 allowing the sequence of studs 7 capable of receiving the bowls 9 by through a cavity 8. The chain of studs 7 thus formed allows the progressive advancement of pods 1 during their manufacturing.

    Selon l'invention, l'installation comprend des moyens particuliers pour déposer une dose 4 dans chaque cuvette 9.According to the invention, the installation comprises means individuals to deposit a dose 4 in each bowl 9.

    A cet effet, ces moyens pourront être constitués d'un ou plusieurs ensembles repérés 10 en figure 3. To this end, these means may consist of one or several assemblies marked 10 in FIG. 3.

    La figure 1 montre une vue plus détaillée de tels ensembles 10.Figure 1 shows a more detailed view of such sets 10.

    Ceux-ci, dont le nombre n'est pas limité pour permettre la formation de doses 4 simultanées et en parallèle, comprennent chacun un compartiment de réserve 11 et un dispositif à tiroir 12 tels qu'illustrés également en figure 1.These, the number of which is not limited to allow the formation of 4 simultaneous and parallel doses, include each a reserve compartment 11 and a drawer device 12 as also illustrated in FIG. 1.

    Le compartiment de réserve 11 assure le stockage du produit à infuser 5. Il permet par ailleurs de délivrer une quantité du produit à infuser 5 vers le dispositif à tiroir 12 par le biais d'une évacuation 22.The reserve compartment 11 ensures the storage of the product to infuse 5. It also makes it possible to deliver a quantity of the product to be infused 5 to the drawer device 12 through an evacuation 22.

    Le dispositif à tiroir 12 comprend quant à lui un trou de réception 14 de la dose 4 situé en vis à vis de l'évacuation 22 du compartiment de réserve 11.The drawer device 12 comprises a hole for reception 14 of dose 4 located opposite evacuation 22 reserve compartment 11.

    Tel qu'illustré en figure 1, le trou de réception 14 a une configuration identique à celle de la dose finale 4 à constituer.As illustrated in FIG. 1, the receiving hole 14 has a identical configuration to that of the final dose 4 to form.

    Le dispositif à tiroir 12 comprend une partie essentielle appelée tiroir 13 apte à être mis en translation une fois que le trou de réception 14 est rempli de la dose 4.The drawer device 12 comprises an essential part called drawer 13 able to be put into translation once the receiving hole 14 is filled with the dose 4.

    Par ce mouvement de translation, le trou de réception 14 peut venir en regard d'une ouverture 23 formée sur l'ensemble 10 afin de délivrer la dose 4 vers la cuvette 9 constituée sur la feuille de papier filtre inférieure 2.By this translational movement, the receiving hole 14 can come next to an opening 23 formed on the assembly 10 in order to deliver the dose 4 to the bowl 9 formed on the lower filter paper sheet 2.

    On assiste donc à un mouvement de va et vient du tiroir 13.We are therefore witnessing a back and forth movement of the drawer 13.

    L'usage de plusieurs ensembles 10 juxtaposés ou, dans un mode de réalisation préféré, d'un seul ensemble 10 comportant plusieurs groupes de trous de réception 14, d'évacuation 22 et d'ouverture 23, permet la réalisation simultanée de plusieurs doses et leur délivrance en parallèle sur la feuille de papier filtre inférieure 2.The use of several sets 10 juxtaposed or, in a preferred embodiment, of a single set 10 comprising several groups of receiving holes 14, evacuation 22 and 23, allows the simultaneous realization of several doses and their parallel delivery on the sheet of paper lower filter 2.

    La figure 2 présente cette possibilité de réalisation assurant une grande productivité.Figure 2 shows this possibility of realization ensuring high productivity.

    Des moyens d'éjection 15 repérés en figure 1 sont présents pour éjecter la dose 4 hors du trou de réception lorsque celui-ci parvient en vis-à-vis de l'ouverture 23 formée au bas dans l'ensemble 10 et débouchant sur les cuvettes 9.Ejection means 15 identified in Figure 1 are present to eject the dose 4 out of the receiving hole when the latter arrives opposite the opening 23 formed at the bottom in the assembly 10 and leading to the bowls 9.

    Un piston 35 réalise les moyens d'éjection 15 par une mobilité axiale entre une position relevée de repos et une position abaissée traversant l'ouverture 23 pour dégager l'intégralité de la dose, la tasser et la mettre en forme.A piston 35 produces the ejection means 15 by a axial mobility between a raised position of rest and a lowered position through opening 23 to release the entire dose, pack it and shape it.

    Le tiroir 13 et le piston 35 sont entraínés par un seul arbre moteur 51 ce qui assure une synchronisation des mouvements suffisamment sûre pour éviter tout blocage ou dysfonctionnement.The drawer 13 and the piston 35 are driven by a single motor shaft 51 which ensures synchronization of movements safe enough to avoid blockage or dysfunction.

    Des moyens de transmission de mouvement entre l'arbre moteur 51 et respectivement le tiroir 13 et le piston35 sont aussi prévus.Means for transmitting movement between the shaft motor 51 and respectively drawer 13 and piston 35 are also planned.

    Il s'agit d'un système à cames 37, 38 montées sur l'arbre moteur 51.It is a cam system 37, 38 mounted on the shaft motor 51.

    En se référant aux figures 4 et 5, la translation du piston 35 est produite par la came 37 sur le profil de laquelle circule un galet 41 lié au piston 35 par le biais d'un cadre 40. De façon connue en soi, la came transforme la rotation de l'arbre 51 en translation du piston 35.Referring to Figures 4 and 5, the translation of the piston 35 is produced by cam 37 on the profile of which circulates a roller 41 linked to the piston 35 through a frame 40. In a manner known per se, the cam transforms the rotation of the shaft 51 in translation of the piston 35.

    Concernant le tiroir 13, la came 38 montée sur l'arbre moteur 51 entraíne, par une extrémité, un levier 42 relié (par pivot) au profil de la came 38 par un galet 44.Regarding the drawer 13, the cam 38 mounted on the shaft motor 51 drives, at one end, a lever 42 connected (by pivot) to the profile of the cam 38 by a roller 44.

    A sa deuxième extrémité, le levier 42 est en liaison pivot avec une biellette 45 solidaire du tiroir 13 directement ou par l'intermédiaire d'une pièce de liaison 48.At its second end, the lever 42 is in pivot connection with a link 45 secured to the drawer 13 directly or by through a connecting piece 48.

    Un pivot 43 assure le mouvement oscillant du levier 42 au cours de la rotation de l'arbre moteur 51 et de la came 38.A pivot 43 ensures the oscillating movement of the lever 42 at the during the rotation of the motor shaft 51 and of the cam 38.

    Des butées avant et arrière limitent avantageusement l'amplitude de l'oscillation du levier 42 et donc la translation du tiroir 13.Front and rear stops advantageously limit the amplitude of the oscillation of the lever 42 and therefore the translation of drawer 13.

    L'arbre moteur 51 est quant à lui l'arbre de sortie de toute motorisation courante, particulièrement un moteur électrique. The motor shaft 51 is the output shaft of any common engine, particularly a motor electric.

    Pour assurer le transfert optimal de la dose 4 vers une cavité 8 et éviter sa chute brutale, il est avantageux d'abaisser l'ensemble 10 (au moins pour ses parties constitutives les plus proches des cavités 8) lors de l'éjection, à un niveau affleurant.To ensure optimal transfer of dose 4 to a cavity 8 and avoid its sudden fall, it is advantageous to lower the set 10 (at least for its parts closest to the cavities 8) when ejection, at a flush level.

    Pour ce faire, le ou les ensembles 10 sont mobiles selon une direction orthogonale aux moyens de support et de formation des cuvettes 9, correspondant aussi à la direction de translation du piston 35.To do this, the assembly or assemblies 10 are movable according to a direction orthogonal to the support and training means bowls 9, also corresponding to the direction of translation of the piston 35.

    Comme pour le tiroir 13 et le piston 35, l'ensemble 10 peut être mu par l'arbre moteur 51, avec une transmission de mouvement par came.As for the drawer 13 and the piston 35, the assembly 10 can be driven by the drive shaft 51, with a transmission of movement by cam.

    A ce sujet, les figures 6 et 7 montrent une came 39 entraínant par pivot sur son profil, par un galet 49, une tige 50 solidaire de l'ensemble 10. Bien entendu, la tige 50 est seulement illustrative d'un exemple de transmission du mouvement vers l'ensemble 10.In this regard, Figures 6 and 7 show a cam 39 driving by pivot on its profile, by a roller 49, a rod 50 integral with the assembly 10. Of course, the rod 50 is only illustrative of an example of transmission of movement towards the assembly 10.

    En se référant aux figures 4 à 9, on note que les profils asymétriques des cames sont adaptés aux mouvements à produire, notamment quant à leur amplitude. Le positionnement angulaire relatif des cames détermine par ailleurs la succession des mouvements du tiroir 13, du piston 35 et de l'ensemble 10.Referring to Figures 4 to 9, we note that the profiles asymmetrical cams are adapted to the movements to be produced, especially as to their amplitude. Angular positioning relative of the cams also determines the succession of movements of the slide 13, the piston 35 and the assembly 10.

    Les figures 4 à 9 illustrent le cas d'un ensemble 10 relevé, d'un piston 35 au repos et d'un tiroir à mi-chemin.Figures 4 to 9 illustrate the case of an assembly 10 raised, a piston 35 at rest and a drawer halfway.

    Avantageusement, les systèmes à cames 37, 38, 39 décrits précédemment sont doublés, aux deux extrémités de l'arbre moteur 51 pour une meilleure répartition des efforts.Advantageously, the cam systems 37, 38, 39 described previously are doubled, at both ends of the tree motor 51 for a better distribution of forces.

    Toujours de façon préférée, une ou plusieurs pâles 52 sont animées d'un mouvement de rotation sensiblement verticale (suivant l'axe du trou de réception 14). La pâle 52 passant à proximité du trou 14 répartit l'acheminement du produit vers le trou 14.Still preferably, one or more blades 52 are driven by a substantially vertical rotational movement (along the axis of the receiving hole 14). The pale 52 passing to near the hole 14 distributes the product routing to the hole 14.

    La figure 6 illustre un mode de réalisation d'une pâle 52 ainsi que son entraínement par pignons et arbre tournant. FIG. 6 illustrates an embodiment of a pale 52 as well as its drive by pinions and rotating shaft.

    La présente installation permet également, selon une variante, de produire des doses 4 de hauteurs différentes, en modifiant la hauteur du tiroir 13.This installation also allows, according to a variant, to produce doses 4 of different heights, in changing the height of the drawer 13.

    Pour s'adapter à ces variations de hauteur et pour s'appliquer précisément sur le tiroir 13, l'évacuation 22 aura une configuration particulière.To adapt to these height variations and to apply precisely to the drawer 13, the discharge 22 will have a particular configuration.

    Dans ce cadre et comme illustré à la figure 6 l'évacuation 22 a une périphérie interne constituée d'une chemise 55 préférentiellement sous forme d'une bague (pour. des doses 4 au profil circulaire).In this context and as illustrated in Figure 6 the evacuation 22 has an internal periphery consisting of a jacket 55 preferably in the form of a ring (for. doses 4 to circular profile).

    La chemise 55 est un guide de translation pour un conduit 53 ajusté et mobile dans celle-ci.The jacket 55 is a translation guide for a conduit 53 adjusted and movable therein.

    Un épaulement 56a a sur la chemise 55, un épaulement 56b sur le conduit 53 ainsi qu'un ressort 54 de compression mettent en suspension le conduit 53 qui s'applique sur la surface supérieure du tiroir 13. Selon la hauteur de ce dernier, le ressort 54 est plus ou moins comprimé.A shoulder 56a a on the shirt 55, a shoulder 56b on the conduit 53 as well as a compression spring 54 put in suspension the conduit 53 which is applied to the surface upper part of drawer 13. Depending on the height of the latter, the spring 54 is more or less compressed.

    Selon un mode de réalisation, le compartiment de réserve 11 comprend un vérin de prétassage 16.According to one embodiment, the reserve compartment 11 includes a pre-pressing cylinder 16.

    Comme représenté, le vérin de prétassage 16 se situe au-dessus de l'évacuation 22.As shown, the pre-pressing cylinder 16 is located above of the evacuation 22.

    De cette façon, le vérin de prétassage 16 peut être actionné pour faciliter le remplissage du trou de réception 14 et éventuellement effectuer un premier tassage de la dose 4 du produit à infuser 5.In this way, the pre-pressing cylinder 16 can be actuated to facilitate filling of the receiving hole 14 and possibly carry out a first tamping of dose 4 of product to be infused 5.

    Pour améliorer encore le fonctionnement de ces ensembles 10, la pression d'alimentation du vérin de prétassage 16 peut être réglable afin d'ajuster la densité de la dose 4.To further improve the functioning of these assemblies 10, the supply pressure of the pre-pressing cylinder 16 can be adjustable to adjust the density of the dose 4.

    En effet, en tassant plus le produit à infuser 5, il est possible d'augmenter la masse volumique finale de la dose 4.In fact, by packing more of the product to be infused 5, it is possible to increase the final density of dose 4.

    Par ce biais, il est également possible d'assurer une régulation en continu du poids des dosettes fabriquées.Through this, it is also possible to ensure continuous regulation of the weight of the manufactured pods.

    Ainsi, l'installation comprendra des moyens de pesage 19, constitués par tout moyen courant, permettant la récupération d'une information 20 de mesure du poids. Cette information de mesure du poids 20 peut être récupérée et traitée au niveau d'un automate programmable 18. Cette transmission de signal est reflétée en figure 1.Thus, the installation will include weighing means 19, constituted by any current means, allowing recovery weight measurement information. This information from weight measurement 20 can be retrieved and processed at level of a programmable controller 18. This signal transmission is reflected in figure 1.

    L'automate programmable est apte, éventuellement après des opérations statistiques, à agir sur la pression d'alimentation du vérin de prétassage 16 afin d'en assurer le rétrocontrôle selon la consigne de poids fixée.The programmable controller is suitable, possibly after statistical operations, to act on the supply pressure of the pre-pressing cylinder 16 in order to ensure the feedback according to the fixed weight instruction.

    Comme indiqué précédemment, les dosettes individuelles 1 peuvent comporter un élément de renfort intercalé entre les deux feuilles de papier filtre 2 et 3 sur le pourtour de la dose 4 de produit à infuser 5.As previously indicated, the individual pods 1 may include a reinforcing element interposed between the two sheets of filter paper 2 and 3 around the edge of the dose 4 of product to be infused 5.

    Pour ce faire, l'installation selon l'invention pourra permettre l'amenée et l'utilisation d'une bande de renfort 24 telle qu'apparaissant en figure 2.To do this, the installation according to the invention may allow the supply and use of a reinforcing strip 24 as shown in Figure 2.

    Dans un mode préféré de réalisation, la bande de renfort est une bande de carton dont les deux faces sont recouvertes d'un film thermoplastique.In a preferred embodiment, the reinforcing strip is a strip of cardboard with two sides covered of a thermoplastic film.

    Pour mettre en oeuvre une telle bande de renfort 24, l'installation comprendra des moyens d'amenée 25 de cette bande de renfort, par exemple constitués de façon similaire aux moyens 6 pour amener les feuilles de papier filtre supérieure et inférieure 2,3.To use such a reinforcing strip 24, the installation will include means for feeding this strip 25 reinforcements, for example formed in a similar way to 6 ways to bring the top filter paper sheets and lower 2.3.

    L'invention comprendra également des moyens de découpe 26 de la bande de renfort 24 pour y former des découpes 27 d'une configuration adaptée à celle des doses 4. Ces découpes 27 viendront en vis à vis des cuvettes 9 formées sur la feuille de papier filtre inférieure 2 de façon à entourer la dose 4.The invention will also include cutting means 26 reinforcing strip 24 to form cutouts 27 therein configuration adapted to that of doses 4. These cuts 27 will face the cuvettes 9 formed on the sheet of lower filter paper 2 so as to surround the dose 4.

    Des moyens de découpe 26 courants pourront être mis en oeuvre notamment par une méthode à l'emporte-pièce.Current cutting means 26 may be used works in particular by a cookie-cutter method.

    L'installation comprendra en outre des moyens d'assemblage de la bande de renfort 24 avec les feuilles de papier filtre 2 et 3. The installation will also include assembly means reinforcement strip 24 with filter paper sheets 2 and 3.

    L'assemblage s'effectue préférentiellement sur le pourtour de la dose 4 au niveau de la bande de renfort 24.The assembly preferably takes place around the perimeter of dose 4 at the reinforcement strip 24.

    Dans un mode préféré de réalisation illustré en figure 3, les moyens d'assemblage sont constitués de têtes chauffantes 28 aptes à venir s'appliquer sur le pourtour de la dose 4 et à assembler par thermocollage les feuilles de papier filtre 2, 3 et la bande de renfort 24.In a preferred embodiment illustrated in FIG. 3, the assembly means consist of heating heads 28 able to be applied around the periphery of dose 4 and join the sheets of filter paper 2, 3 by heat sealing and the reinforcing strip 24.

    Pour assurer un thermocollage efficace, la bande de renfort 24 sera préférentiellement constituée d'une bande de carton dont les deux faces sont recouvertes d'un film thermoplastique.To ensure effective heat sealing, the reinforcing strip 24 will preferably consist of a strip of cardboard both sides of which are covered with a thermoplastic film.

    Lors de la fabrication des dosettes 1, les feuilles de papier filtre 2 et 3 subissent des déformations qui les sollicitent fortement. C'est essentiellement le cas lors de la formation des cuvettes 9 sur la feuille de papier filtre inférieure 2 et lors de la couverture de la dose 4 par la feuille de papier filtre supérieure 3 qui doit épouser la forme bombée de la dose 4.During the production of pods 1, the sheets of filter paper 2 and 3 undergo deformations which strongly solicit. This is essentially the case during the formation of bowls 9 on the filter paper sheet lower 2 and when covering dose 4 by the upper sheet of filter paper 3 which should fit the shape bulge of dose 4.

    Pour éviter que ces sollicitations produisent des arrachements des feuilles de papier filtre 2 et 3, l'invention pourra comprendre des moyens d'avance supplémentaires 29.To prevent these stresses from producing tearing of the sheets of filter paper 2 and 3, the invention may include additional means of advance 29.

    Tels que représentés en figure 3, sous forme d'un rouleau d'entraínement, les moyens d'avance 29 sont aptes à augmenter la vitesse de déplacement de la feuille de papier filtre 2 ou 3 relativement à la bande de renfort 24 avant leur assemblage.As shown in Figure 3, in the form of a roll drive, the advance means 29 are capable of increasing the speed of movement of the filter paper sheet 2 or 3 relative to the reinforcing strip 24 before their assembly.

    On constate ainsi en aval des moyens d'avance supplémentaire 29 la formation d'un relâchement 30 sur la feuille de papier filtre 2 permettant d'éviter de trop fortes tensions lors des formations des cuvettes 9.We thus see downstream means of advance additional 29 the formation of a loosening 30 on the filter paper sheet 2 to avoid too strong tensions during bowl formation 9.

    Les moyens d'avance supplémentaire 29 permettent de limiter les contraintes appliquées en tension sur les feuilles de papier filtre dans le sens du déplacement de ces feuilles.The additional advance means 29 make it possible to limit the stresses applied in tension on the sheets of filter paper in the direction of movement of these sheets.

    Pour obtenir le même résultat dans le sens transverse au déplacement, l'invention pourra en outre comprendre des moyens pour fendre au moins partiellement la ou les feuilles de papier filtre 2,3 à proximité des cuvettes 9. Comme représenté en figure 2 en trait pointillé, les fentes 31 réalisées s'orienteront suivant la direction du déplacement des feuilles et offrent une liberté de mouvement interne supplémentaire aux feuilles de papier filtre 2 et 3.To obtain the same result in the transverse direction to displacement, the invention may also include means to at least partially split the sheet or sheets of paper filter 2,3 near the bowls 9. As shown in Figure 2 in dotted lines, the slots 31 made will orient themselves in the direction of movement of the leaves and provide additional internal freedom of movement for sheets of filter paper 2 and 3.

    Les moyens pour fendre pourront par exemple être constitués d'un rouleau comportant à sa périphérie des tranchants s'appliquant sous pression sur les feuilles de papier filtre 2 et 3.The means for splitting may for example be constituted a roller with cutting edges at its periphery applied under pressure on sheets of filter paper 2 and 3.

    Dans le cadre d'une utilisation d'une bande de renfort 24, les moyens de découpe 26 pourront en outre comprendre des moyens aptes à perforer la bande de renfort 24 à espace régulier. On forme ainsi des trous 32 alignés et uniformément répartis dans la direction de déplacement sur la bande de renfort 24 tel que cela apparaít également en figure 2.In the context of the use of a reinforcing strip 24, the cutting means 26 may further include means capable of perforating the reinforcing strip 24 with space regular. Holes 32 are thus formed aligned and uniformly distributed in the direction of movement on the strip of reinforcement 24 as it also appears in FIG. 2.

    Les trous 32 peuvent coopérer avec un ou plusieurs rouleaux à picot 33 dont les picots s'insèrent dans les trous 32 pour assurer un positionnement régulier et éventuellement un entraínement de la bande de renfort 24.The holes 32 can cooperate with one or more picot rollers 33 whose pins fit into the holes 32 to ensure regular positioning and possibly a drive of the reinforcing strip 24.

    Dans un mode préférentiel de réalisation, on fait coopérer les alignements de trous 32 avec les fentes 31 formées sur les feuilles de papier filtre supérieure et inférieure 2, 3. De cette façon, la mise en place des picots des rouleaux à picots 33 dans les trous 32 peut être effectuée sans devoir perforer les feuilles de papier filtre 2,3.In a preferred embodiment, cooperation is made the alignments of holes 32 with the slots 31 formed on the upper and lower filter paper sheets 2, 3. From this way the placement of the pins of the pin rollers 33 in the holes 32 can be made without having to punch sheets of filter paper 2.3.

    Suivant un autre mode de réalisation, l'installation ici présentée comprend une tête d'injection 34 d'un gaz inerte au sein de la dose 4 de produit à infuser 5.According to another embodiment, the installation here presented comprises an injection head 34 of an inert gas at within the dose 4 of product to be infused 5.

    De cette façon, le gaz inerte injecté évacue l'oxygène résiduel présent dans la dose 4. On assure ainsi une meilleure conservation du café avec des qualités gustatives optimales.In this way, the injected inert gas evacuates the oxygen residual in dose 4. This ensures better conservation of coffee with optimal taste qualities.

    Préférentiellement, on utilisera de l'azote comme gaz inerte. Preferably, nitrogen will be used as the gas inert.

    Le fonctionnement de l'installation selon la présente invention peut s'articuler suivant les étapes décrites ci-après et selon le procédé de fabrication selon l'invention.The operation of the installation according to this invention can be articulated according to the steps described below and according to the manufacturing method according to the invention.

    Dans un premier temps, on amène les deux feuilles de papier filtre 2,3 depuis des moyens de stockage.First, we bring the two sheets of paper filter 2.3 from storage means.

    Sur la première feuille de papier filtre, la feuille inférieure 2, on forme des cuvettes 9. Durant cette étape, la feuille de papier filtre 2 est supportée par exemple par le biais d'une bande roulante 21 comportant une série de plots 7 dotés de cavités 8 où s'intègrent les cuvettes 9.On the first sheet of filter paper, the sheet lower 2, bowls 9 are formed. During this step, the sheet of filter paper 2 is supported for example by the bias of a tread 21 comprising a series of studs 7 provided with cavities 8 where the bowls 9 are integrated.

    Lorsque les cuvettes 9 sont formées, on dépose une dose 4 du produit à infuser 5.When the bowls 9 are formed, a dose 4 is deposited of the product to be infused 5.

    Ensuite, on déplace les dosettes 1 en cours de formation vers des étapes de fabrication suivantes.Then, we move the pods 1 during training to next manufacturing steps.

    En ce qui concerne le dépôt d'une dose 4 du produit à infuser 5, l'invention a la particularité de comporter les étapes suivantes :

    • on stocke le produit à infuser 5 dans un compartiment de réserve 11
    • on évacue une dose 4 depuis ce compartiment de réserve 11 vers un trou de réception 14 constitué dans un dispositif à tiroir 13.
    • on effectue ensuite un mouvement de translation du tiroir 12 pour amener la dose 4 présente dans le trou de réception 14 vers un emplacement où on l'éjecte vers la cuvette 9. Cet emplacement peut être constitué par une ouverture 23 formée en partie inférieure de l'ensemble 10.
    As regards the deposit of a dose 4 of the product to be infused 5, the invention has the particularity of comprising the following stages:
    • the product to be infused 5 is stored in a reserve compartment 11
    • a dose 4 is discharged from this reserve compartment 11 to a receiving hole 14 formed in a drawer device 13.
    • a translational movement of the drawer 12 is then carried out to bring the dose 4 present in the receiving hole 14 to a location where it is ejected towards the bowl 9. This location can be constituted by an opening 23 formed in the lower part of the together 10.

    L'éjection et éventuellement un tassage de la dose 4 peut être effectué par le biais de moyens d'éjection 15 sous forme d'un piston 35 translatif.The ejection and possibly packing of dose 4 may be carried out by means of ejection 15 in the form a translating piston 35.

    Pour faciliter la constitution de la dose 4 dans le trou de réception 14, un prétassage du produit à infuser 5 peut être réalisé lors de son évacuation. To facilitate the constitution of the dose 4 in the hole of reception 14, pre-brewing of the product to be infused 5 can be made during its evacuation.

    Par ailleurs, on peut régler la pression du prétassage réalisé par un vérin de prétassage 16 de façon à faire varier la densité de la dose 4 suivant une consigne voulue.You can also adjust the pre-pressing pressure produced by a pre-pressing cylinder 16 so as to vary the density of the dose 4 according to a desired instruction.

    Dans ce sens, il est particulièrement avantageux de réaliser un rétrocontrôle du poids des doses 4 du produit à infuser 5.In this sense, it is particularly advantageous to perform a feedback on the weight of the doses 4 of the product to infuse 5.

    Pour ce faire, on pèse tout ou partie des dosettes fabriquées 1 et, par exploitation du signal de mesure 20 qui en ressort, on régule la pression de prétassage selon les écarts constatés entre les pesées et la consigne de poids fixée.To do this, we weigh all or part of the pods manufactured 1 and, by exploiting the measurement signal 20 which spring, we regulate the pre-pressing pressure according to the deviations observed between the weighings and the fixed weight instruction.

    Suivant le mode de réalisation où les dosettes 1 comprennent un élément de rigidité sur le pourtour de la dose 4, on amène une bande de renfort 24.According to the embodiment where the pods 1 include an element of rigidity around the perimeter of the dose 4, a reinforcing strip 24 is brought in.

    On assure ensuite une découpe dans la bande de renfort 24 en adaptant la configuration de ces découpes à la configuration des doses.A cut is then made in the reinforcing strip 24 by adapting the configuration of these cuts to the configuration doses.

    On ajuste ensuite la position des découpes ainsi réalisées vis à vis des cuvettes 9 formées sur la feuille de papier filtre inférieure 2.The position of the cuts thus produced is then adjusted with respect to the bowls 9 formed on the sheet of paper lower filter 2.

    On peut ensuite poser la bande de renfort 24 sur la feuille de papier filtre inférieure 2 puis venir positionner la feuille de papier filtre supérieure 3 sur la face supérieure de la bande de renfort 24.We can then put the reinforcement strip 24 on the sheet of lower filter paper 2 then position the sheet upper filter paper 3 on the upper side of the reinforcement strip 24.

    La bande de renfort 24 se trouve alors intercalée entre les deux feuilles de papier filtre 2, 3 puis elles sont assemblées. . A noter que préférentiellement, l'étape de superposition de la bande de renfort 24 et de la feuille de papier filtre inférieure 2 s'effectue avant le dépôt de la dose 4 du produit à infuser 5. Cependant, cette solution n'est pas limitative.The reinforcing strip 24 is then interposed between the two sheets of filter paper 2, 3 then they are assembled. . Note that preferably, the superposition step of the reinforcing strip 24 and the sheet of filter paper lower 2 is carried out before the deposit of the dose 4 of the product to infuse 5. However, this solution is not limiting.

    Dans un mode préféré, la bande de renfort comprend deux faces recouvertes d'un film thermoplastique de façon à pouvoir l'assembler aux feuilles de papier filtre 2, 3 par thermocollage. In a preferred mode, the reinforcing strip comprises two sides covered with a thermoplastic film so that assemble it with the sheets of filter paper 2, 3 by fusing.

    On résume ci-après de façon successive les étapes de transformation de la dosette 1 au cours de sa fabrication.We successively summarize the stages of transformation of the pod 1 during its manufacture.

    On amène tout d'abord une feuille de papier filtre inférieure 2 par le biais de moyens d'amenée 6.First we bring a sheet of filter paper lower 2 by means of supply 6.

    Dans le cas où une bande de renfort 24 est utilisée, celle-ci est également amenée par des moyens 25 pouvant être de conception similaire.In the case where a reinforcing strip 24 is used, it is also brought by means 25 which can be of similar design.

    Au cours de son amenée, la bande de renfort 24 subit des découpes 27 par le biais de moyens de découpe 26.During its supply, the reinforcing strip 24 undergoes cuts 27 by cutting means 26.

    La bande de renfort 24 et la feuille de papier filtre inférieure 2 sont alors sensiblement superposées.The reinforcement strip 24 and the sheet of filter paper lower 2 are then substantially superimposed.

    De façon préférentielle, on entraíne à une vitesse légèrement supérieure la feuille de papier filtre 2 vis à vis de la bande de renfort 24. Il s'ensuit alors un relâchement 30 comme représenté en figure 3 avant l'étape d'assemblage.Preferably, we train at a speed slightly higher the sheet of filter paper 2 opposite of the reinforcing strip 24. It then follows a relaxation 30 as shown in Figure 3 before the assembly step.

    On forme alors les cuvettes 9 sur la surface de la feuille de papier filtre inférieure 2.The bowls 9 are then formed on the surface of the sheet. lower filter paper 2.

    Puis, on effectue l'assemblage notamment par thermocollage de la feuille de papier filtre 2 et de la bande de renfort 24.Then, the assembly is carried out in particular by heat bonding of the sheet of filter paper 2 and of the reinforcing strip 24.

    L'avance de cet ensemble se poursuit alors vers les moyens aptes à déposer une dose 4 de produit à infuser 5.The advance of this set then continues towards the means suitable for depositing a dose 4 of product to be infused 5.

    Ce dépôt s'effectue par l'évacuation d'une quantité de produit à infuser 5 dans un trou de réception 14 formé sur un tiroir 12. Ce tiroir 12 subit ensuite un mouvement de translation vers une zone d'éjection où la dose 4 sera déposée dans la cuvette 9. Avantageusement, l'ensemble 10 est abaissé pour une éjection de la dose 4 à proximité de la cuvette 9.This deposit is made by the evacuation of a quantity of product to be infused 5 into a receiving hole 14 formed on a drawer 12. This drawer 12 then undergoes a movement of translation to an ejection area where dose 4 will be deposited in the bowl 9. Advantageously, the assembly 10 is lowered for ejection of dose 4 near bowl 9.

    Il s'agit alors de recouvrir la dosette 1 de la feuille de papier filtre supérieure 3.It is then a question of covering the pod 1 of the sheet of upper filter paper 3.

    Pour ce faire, des moyens d'amenée 6 assurent l'arrivée de la feuille de papier filtre supérieure 3 au-dessus de la dosette 1 ainsi partiellement constituée.To do this, supply means 6 ensure the arrival of the top filter sheet 3 above the pod 1 thus partially formed.

    En appliquant une tête chauffante 28 au-dessus de la feuille de papier filtre supérieure 3, on assure sa déformation pour épouser la surface supérieure de la dose 4 et son assemblage par thermocollage sur les pourtours de la dose 4.By applying a heating head 28 above the upper filter paper sheet 3, its deformation is ensured to match the upper surface of dose 4 and its assembly by heat-bonding around the edges of dose 4.

    Par la suite, il est possible d'évacuer l'oxygène résiduel au sein de la dose 4 par le biais d'une injection d'un gaz inerte tel que de l'azote.Thereafter, it is possible to evacuate the residual oxygen within dose 4 through injection of a gas inert such as nitrogen.

    On forme ainsi une nappe de dosettes 1 qui sont utilisables après découpe. Cette découpe peut être effectuée après les étapes décrites ci-dessus pour constituer des dosettes individuelles.This forms a sheet of pods 1 which can be used after cutting. This cutting can be done after steps described above to make pods individual.

    Tel que cela vient d'être décrit, on réalise des dosettes 1 en série et alignées suivant le sens de déplacement de l'installation.As just described, pods 1 are produced in series and aligned in the direction of movement of installation.

    De façon préférentielle, on réalisera en outre une fabrication en parallèle de plusieurs lignes ou séries des dosettes 1 ici présentées.Preferably, one will also carry out a parallel production of several lines or series of pods 1 presented here.

    La figure 2 présente la réalisation de quatre dosettes en parallèle. Figure 2 shows the realization of four pods in parallel.
