De nombreux produits alimentaires apparaissent dans le commerce avec une sorte d'emballage comestible entourant de façon partiellement fermée, fermée et même étanche, une garniture de consistance quasi-solide. De tels produits nécessitent, pour leur fabrication, le remplissage d'une dose de garniture sur la feuille de matière alimentaire puis une succession de pliages et/ou de roulages de ladite feuille de manière à entourer la garniture. Cette succession de pliages s'effectue manuellement et par conséquent s'avère très coûteuse et très longue à mettre en œuvre.Many food products appear on the market with a kind of edible packaging surrounding in a partially closed, closed and even sealed manner, a filling of almost solid consistency. Such products require, for their manufacture, filling a dose of filling on the sheet of food material and then a succession of folds and / or rolling of said sheet so as to surround the filling. This succession of folds is carried out manually and therefore proves to be very expensive and very time-consuming to implement.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, en se référant aux dessins annexes sur lesquelsThe characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, with reference to the accompanying drawings in which
- la figure 1 est une vue schématique du dispositif de pliage selon la présente invention, etFIG. 1 is a schematic view of the folding device according to the present invention, and
- les figures 2 à 5 illustrent le fonctionnement du dispositif de pliage représenté à la figure 1- Figures 2 to 5 illustrate the operation of the folding device shown in Figure 1
On a représenté à la figure 1 , un dispositif (1 ) permettant le pliage d'une feuille de matière alimentaire (2), du type galette de riz, remplie d'une garniture (3) de manière à former un emballage comestible avec cette dernière De manière classique, en amont du dispositif (1 ) est disposé un tapis convoyeur (4) d'amenage de feuilles de matière alimentaire (2) présentant, par exemple la forme générale d'un cercle et un moyen de dépôt (5) d'un volume de garniture sur lesdites feuilles de matière (2), dont la consistance peut être solide, granuleuse ou pâteuse. En aval du dispositif (1 ) est agencé un second tapis (10) convoyeur destiné à évacuer les feuilles de matière alimentaire (2) remplies de leur garniture (3) et pliées.There is shown in Figure 1, a device (1) for folding a sheet of food material (2), of the rice pancake type, filled with a filling (3) so as to form an edible package with this latest Conventionally, upstream of the device (1) is arranged a conveyor belt (4) for feeding sheets of food material (2) having, for example the general shape of a circle and a depositing means (5) d 'a volume of filling on said sheets of material (2), the consistency of which may be solid, grainy or pasty. Downstream of the device (1) is arranged a second conveyor belt (10) intended to evacuate the sheets of food material (2) filled with their filling (3) and folded.
Le dispositif de pliage (1 ), selon la présente invention, est constitué, selon un mode de réalisation préférentielle, d'un premier moyen de pliage (6) de la partie amont de la matière alimentaire, d'une paire de moyens de pliage (7 et 8) des côtés de ladite matière, d'un tapis convoyeur (9) et d'un moyen de roulage (10) de l'ensemble avant que celui-ci ne soit évacué par le second tapis convoyeur, non représenté.The folding device (1) according to the present invention consists, according to a preferred embodiment, of a first folding means (6) of the upstream part of the food material, of a pair of folding means (7 and 8) on the sides of said material, a conveyor belt (9) and a rolling means (10) of the assembly before it is removed by the second conveyor belt, not shown.
Le premier moyen de pliage (6) est constitué d'un rouleau motorisé apte à prendre progressivement et successivement une première position dans laquelle ledit rouleau est situé dans le prolongement du tapis (4) et transversalement à ce dernier, et une seconde position dans laquelle le rouleau est en élévation par rapport au plan parallèle du tapis.The first folding means (6) consists of a motorized roller capable of gradually and successively assuming a first position in which said roller is located in the extension of the belt (4) and transverse to the latter, and a second position in which the roller is in elevation relative to the parallel plane of the belt.
Comme visible sur les figures représentant un mode de réalisation, le rouleau (6) est supporté, par l'intermédiaire de son axe de rotation (A), par deux bras parallèles (1 1 ) aptes à pivoter d'une première position dite de repos, dans laquelle ledit rouleau (6) est situé dans le prolongement du tapis et transversalement à ce dernier, jusqu'à une seconde position dans laquelle le rouleau (6) est en élévation, comme mentionné ci-dessus.As visible in the figures representing an embodiment, the roller (6) is supported, via its axis of rotation (A), by two parallel arms (1 1) capable of pivoting from a first position called rest, in which said roller (6) is located in the extension of the belt and transverse to the latter, to a second position in which the roller (6) is in elevation, as mentioned above.
Le mouvement de pivotement est assuré par exemple par une came (12), ou tous types d'actionneurs. De même, le rouleau (6) est motorisé en rotation par un jeu de courroies (13) dont la mise en rotation est commandée par une unité de commande électronique, non représentée, en fonction de signaux de capteurs, du type capteur de présence de la feuille de matière alimentaire (2), au travers du dispositif (1 ).The pivoting movement is provided for example by a cam (12), or all types of actuators. Likewise, the roller (6) is motorized in rotation by a set of belts (13) whose rotation is controlled by an electronic control unit, not shown, as a function of sensor signals, of the presence sensor type. the sheet of food material (2), through the device (1).
La paire de moyens de pliage (7 et 8) est constituée de deux rouleaux motorisés et mobiles interposés en position de repos dans le tapis de convoyage (9). Ces rouleaux sont disposés, avantageusement, suivant la direction longitudinale du tapis de convoyage (9). Chacun de ces rouleaux (7, 8) est apte à décrire un mouvement d'arc de cercle -ou horizontal- en direction du rouleau opposé dans un plan transversal par rapport au sens du déplacement de la feuille de matière (2) et ce de manière déphasée l'un par rapport à l'autreThe pair of folding means (7 and 8) consists of two motorized and movable rollers interposed in the rest position in the conveyor belt (9). These rollers are advantageously arranged in the longitudinal direction of the conveyor belt (9). Each of these rollers (7, 8) is suitable for describe a circular arc movement - or horizontal - in the direction of the opposite roller in a transverse plane relative to the direction of movement of the sheet of material (2) and this out of phase with respect to each other
Selon une variante de réalisation, les moyens de pliage (7 et 8) précitées peuvent être constitués de plusieurs rouleaux disposés suivant des angles variables par rapport au tapisAccording to an alternative embodiment, the above-mentioned folding means (7 and 8) may consist of several rollers arranged at variable angles relative to the belt
On notera que chacun des rouleaux (7, 8) est monté fixement à un bras mobile (14) suivant successivement une direction verticale dirigée vers le haut, comme visible sur fa figure 2 (Flèche B), puis suivant une direction oblique (Flèche C) dirigée vers le bas de manière à faire décrire à chacun des rouleaux (7, 8) le mouvement d'arc de cercle décrit ci-dessus La mobilité de chacun des bras (14) est assurée par exemple au moyen d'un système constitué d'un jeu de cames (15) commandé en rotation par l'unité de commande électronique, en fonction de signaux de capteurs de présence de la feuille de matière alimentaire (2) Ce jeu de cames (15) permet avantageusement la mise en déphasage des mouvements des bras (14)It will be noted that each of the rollers (7, 8) is fixedly mounted to a movable arm (14) successively in a vertical direction directed upwards, as visible in the figure 2 (arrow B), then in an oblique direction (arrow C ) directed downwards so as to make each of the rollers (7, 8) describe the circular arc movement described above The mobility of each of the arms (14) is ensured for example by means of a system a set of cams (15) controlled in rotation by the electronic control unit, as a function of signals from sensors of the presence of the sheet of food material (2) This set of cams (15) advantageously allows phase shifting arm movements (14)
De même, chacun des rouleaux (7, 8) est entraîne en rotation par un système constitué de jeux de roues dentées menées (16), reliées entre elles par une tige logée à l'intérieur du bras (14) entraînées en rotation par une roue dentée menante (17) apte à coopérer successivement avec une première (18) et une seconde (19) crémaillère solidaires d'un bâti (20)Similarly, each of the rollers (7, 8) is driven in rotation by a system consisting of sets of driven toothed wheels (16), connected together by a rod housed inside the arm (14) driven in rotation by a driving gear (17) able to cooperate successively with a first (18) and a second (19) rack fixed to a frame (20)
On notera que les sens de rotation des rouleaux (7, 8) constituant la paire de moyens de pliage sont opposés de manière à ramener la feuille de matière alimentaire vers l'intérieur de celle-ciIt will be noted that the directions of rotation of the rollers (7, 8) constituting the pair of folding means are opposite so as to bring the sheet of food material towards the interior thereof.
De manière avantageuse, les rouleaux (6, 7 et 8) constituant les moyens de pliage sont aménagés suivant les nécessites liées aux phénomènes d'adhérences, de forme diminuant les surfaces de contact, tels qu'une rainure hélicoïdale simple ou a plusieurs filets avec, de préférence, le sommet arrondi ou des rainures radiales réalisant la même fonction dans le but et d'éviter au maximum les surfaces de contact entre la matière alimentaire comestible et le rouleau Selon une variante, cette fonction peut être réalisée avec un rouleau lisse sur lequel on glisse un filet élastique ou non diminuant de ce fait le surface de contactAdvantageously, the rollers (6, 7 and 8) constituting the folding means are arranged according to the needs linked to the phenomena of adhesions, in form reducing the contact surfaces, such as a simple helical groove or with several threads with , preferably, the rounded top or radial grooves performing the same function for the purpose and to avoid as much as possible the contact surfaces between the edible food material and the roll. According to a variant, this function can be carried out with a smooth roll on which one slides an elastic net or not thereby reducing the contact surface
Selon une variante de réalisation, la paire de moyens de pliage (7, 8) est constituée de deux courroies tournantes latérales vrillées.According to an alternative embodiment, the pair of folding means (7, 8) is made up of two twisted lateral rotating belts.
Le moyen de roulage, non schématisé, est constitué de deux tapis superposés et espacés l'un de l'autre, et dont l'un est mobile par rapport à l'autre.The rolling means, not shown, consists of two superimposed belts spaced from one another, one of which is movable relative to the other.
On notera qu'avantageusement ces tapis sont réalisés en acier inoxydable présentant la forme générale d'une cotte de maille, la maille de cette dernière pouvant varier suivant la matière de la feuille à rouler.It will be noted that advantageously these carpets are made of stainless steel having the general shape of a coat of mesh, the mesh of the latter possibly varying according to the material of the sheet to be rolled.
Le fonctionnement du dispositif selon la présente invention va maintenant être expliqué en relation avec les figures 1 à 5.The operation of the device according to the present invention will now be explained in relation to FIGS. 1 to 5.
On comprend à la lecture de la description ci-dessus que le tapis convoyeur (4) amène les feuilles de matière alimentaire (2) préalablement séparées par confection ou coupées par une bande, jusqu'au droit d'un moyen doseur, non représenté, destiné à remplir la feuille (2) d'un volume de garnitureIt is understood from reading the description above that the conveyor belt (4) brings the sheets of food material (2) previously separated by making up or cut by a strip, to the right of a metering means, not shown, intended to fill the sheet (2) with a volume of filling
(3), situé de préférence sur le tapis convoyeur (4). Cette feuille (2) remplie de sa garniture (3) est ensuite amenée au droit du premier moyen de pliage (6). Un détecteur de présence, non représenté, transmet un signal à l'unité de commande qui transmet l'ordre d'entraîner en rotation, dans le sens inverse du déplacement du tapis, le rouleau (6) ainsi que son déplacement progressif de sa première position dite position de repos à sa seconde position repliant ainsi la partie amont de la feuille (2) sur la garniture (3). La partie aval est alors entraînée par le tapis de convoyage (4) jusqu'à son basculement sur le tapis de convoyage(3), preferably located on the conveyor belt (4). This sheet (2) filled with its lining (3) is then brought to the right of the first folding means (6). A presence detector, not shown, transmits a signal to the control unit which transmits the order to drive in rotation, in the opposite direction of the movement of the carpet, the roller (6) as well as its progressive movement from its first so-called rest position in its second position thus folding the upstream part of the sheet (2) onto the lining (3). The downstream part is then driven by the conveyor belt (4) until it tips over the conveyor belt
(9) du dispositif, formant ainsi le premier pli.(9) of the device, thus forming the first fold.
Le tapis de convoyage (9) amène la feuille de matière (2) à une certaine position au dessus de la paire de moyen de pliages (7, 8). Après un certain laps de temps, l'unité de commande déplace de manière déphasée dans le temps respectivement chacun des bras (14) en direction verticale (Flèche B) vers le haut puis de manière oblique (Flèche C) vers le bas et concomitamment la rotation des rouleaux (7, 8) réalisant ainsi successivement un second et un troisième plis sur la garniture (3). Chacun des bras (14) est rappelé à sa position initiale, figure 5, au moyen d'actionneurs, non représentés.The conveyor belt (9) brings the sheet of material (2) to a certain position above the pair of folding means (7, 8). After a certain period of time, the control unit moves in a phase-shifted manner in time respectively each of the arms (14) in vertical direction (arrow B) upwards then obliquely (arrow C) downwards and concomitantly the rotation of the rollers (7, 8) thus successively producing a second and a third fold on the lining (3). Each of the arms (14) is returned to its initial position, FIG. 5, by means of actuators, not shown.
La feuille de matière alimentaire (2) ainsi pliée est apte à être convoyée par le tapis de convoyage (9) entre l'espace formé par les deux bras mobiles (14) jusqu'au moyen de roulage (10).The sheet of food material (2) thus folded is capable of being conveyed by the conveyor belt (9) between the space formed by the two movable arms (14) up to the rolling means (10).
Lors du déplacement au travers du moyen de roulage, la feuille de matière alimentaire s'accroche sur les différentes mailles constituant les tapis entraînant un enroulement et un déplacement de celle-ci jusqu'au tapis de convoyage d'évacuation de la feuille.When moving through the rolling means, the sheet of food material hangs on the different meshes constituting the belts causing a winding and displacement thereof to the conveyor belt for discharging the sheet.
On comprend à la lecture de la description ci-dessus que le dispositif de la présente invention est relativement simple à réaliser et permet la réalisation d'un emballage comestible autour d'une garniture de manière très aisée, par la réalisation d'au moins un moyen de pliage apte à saisir l'un des bords de la feuille et à lui impulser simultanément un mouvement inverse au mouvement de déplacement de la partie arrière de la feuille.It will be understood from reading the description above that the device of the present invention is relatively simple to produce and allows the production of an edible packaging around a filling very easily, by the production of at least one folding means able to grasp one of the edges of the sheet and to simultaneously impulse a movement opposite to the movement of movement of the rear part of the sheet.
Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier elle comprend tous les équivalents techniques des moyens décrits.Although the invention has been described in connection with a particular embodiment, it includes all the technical equivalents of the means described.
Ainsi, les différents mouvements des différents bras supportant les rouleaux peuvent être entraînés par des actionneurs. Thus, the different movements of the different arms supporting the rollers can be driven by actuators.
