INSTALLATION DE TRI AUTOMATIQUE AUTOMATIC SORTING INSTALLATION
La présente invention concerne une installation de tri automatique, apte à répartir des produits selon une caractéristique différenciatrice préalablement détec¬ tée ; elle concerne en particulier, mais de façon non exclusive, une trieuse pondérale permettant le calibrage de tous types de produits du genre poissons, volailles, quartiers de viande et autres...The present invention relates to an automatic sorting installation, capable of distributing products according to a differentiating characteristic previously detected; it relates in particular, but not exclusively, to a checkweigher allowing the calibration of all types of products such as fish, poultry, meat quarters and the like ...
Dans certains domaines techniques et notamment dans l'industrie agroalimentaire, on cherche à trier les produits qui sont disposés en vrac ou qui défilent les uns à la suite des autres, notamment en fonction de leur poids ou de leur calibre, pour réaliser un conditionnement homogène.In certain technical fields and in particular in the food industry, it is sought to sort the products which are arranged in bulk or which pass one after the other, in particular according to their weight or their caliber, in order to carry out a homogeneous packaging. .
Habituellement, ces opérations de tri sont réalisées à la main, à l'aide d'une balance, ou après évaluation visuelle de l'opérateur. Cette technique nécessite cependant une main d'oeuvre importante, elle limite les cadences et grève les coûts de manutention.Usually, these sorting operations are carried out by hand, using a balance, or after visual evaluation by the operator. However, this technique requires a large workforce, it limits the rates and strikes handling costs.
Pour remédier à ces inconvénients, on a mis au point des trieuses pondérales basées sur le principe d'éjection appelé "flipper".To overcome these drawbacks, checkweighers have been developed based on the ejection principle called "flipper".
Ce type de matériel est constitué d'un convoyeur sans fin d'amenée des produits, par exemple du type tapis accélérateur, à la suite duquel est disposé un convoyeur balance apte à détecter le poids des produits au moyen de jauges de contrainte ou de pesons du type à flexion ou à compression. Le tapis de pesée est prolongé par un troisième convoyeur sans fin, muni, sur sa longueur, d'une succession de balais latéraux du type "flippers" associés chacun à un bac de récupération. Les "flippers" consistent en une lame métallique ou plastique disposée juste au- dessus du tapis de convoyage et susceptible de balayer transversalement le plan de transport pour éjecter les produits sur le côté. Leur mouvement est commandé par les informations du tapis de pesée pour évacuer chaque produit dans le bac choisi, en fonction de son poids.This type of equipment consists of an endless product conveyor, for example of the accelerator belt type, following which is arranged a balance conveyor capable of detecting the weight of the products by means of strain gauges or load cells. of the flexion or compression type. The weighing belt is extended by a third endless conveyor, provided, along its length, with a succession of side brushes of the "pinball" type each associated with a recovery tank. The "pinball machines" consist of a metal or plastic blade placed just above the conveyor belt and capable of sweeping across the transport plane to eject the products from the side. Their movement is controlled by the information on the weighing belt to evacuate each product in the chosen bin, depending on its weight.
Le "flipper" s'ouvre et se referme en un tiers de seconde environ et ce type d'installation autorise des cadences de l'ordre de trois produits par seconde.. Or, le maintien de telles cadences nécessite une ouverture et une fermeture rapide du "flipper" qui implique un contact violent lors de l'éjection du produit ; cetteThe "flipper" opens and closes in about a third of a second and this type of installation allows rates of the order of three products per second. However, maintaining such rates requires rapid opening and closing of the "flipper" which involves violent contact when the product is ejected; this

La présente invention a pour but de remédier à l'ensemble de ces inconvénients en proposant une installation de tri automatique pouvant être utilisée pour trier tous types de produits, quels que soient leurThe aim of the present invention is to remedy all of these drawbacks by proposing an automatic sorting installation which can be used to sort all types of products, whatever their

Cette installation de tri automatique est du type constituée d'un premier système de convoyage comportant des moyens de détection de la caractéristique différen¬ ciatrice recherchée des produits, suivi d'un second système de convoyage muni de moyens assurant le tri des produits selon leur caractéristique différenciatrice. Ces moyens de tri sont constitués d'au moins un convoyeur sans fin en forme de trappe, lequel convoyeur est mobile autour d'un axe perpendiculaire à la direction de convoyage et est associé à des moyens de commande qui assurent son positionnement dans le plan de convoyage pour laisser passer les produits, et son écartement de ce pla.n pour assurer leur évacuation.This automatic sorting installation is of the type consisting of a first conveying system comprising means for detecting the desired differential characteristic of the products, followed by a second conveying system provided with means ensuring the sorting of the products according to their differentiating characteristic. These sorting means consist of at least one endless hatch-shaped conveyor, which conveyor is movable about an axis perpendicular to the conveying direction and is associated with control means which ensure its positioning in the plane of conveying to let the products pass, and its spacing from this pla.n to ensure their evacuation.
Selon l'invention, cette installation comporte des moyens d'adaptation de l'angle d'ouverture et/ou du temps d'ouverture de la trappe en fonction des caractéristiques d'encombrement du produit évacué. On réduit ainsi les pertes de temps liées à l'ouverture plus ou moins grande ou plus ou moins longue des trappes et on peut optimiser les cadences d'approvisionnement en amont. Le plus souvent on réglera l'angle d'ouverture et le temps d'ouverture des trappes. Dans des cas particuliers, en fonction des produits traités, l'un des paramètres pourra être fixé à l'avance et le réglage se fera en cours de traitement sur le second paramètre. Selon une première disposition de l'invention, l'installation comporte des moyens de détermination de la hauteur du produit qui ont une action sur l'angle d'ouverture de la trappe correspondant à son affectation. Selon une autre disposition, elle comporte des moyens de détermination de la longueur du produit agissant sur le temps d'ouverture de la trappe qui correspond à son affectation.According to the invention, this installation comprises means for adapting the opening angle and / or the opening time of the hatch as a function of the dimensions of the size of the product discharged. This reduces the loss of time associated with the more or less large or more or less long opening of the hatches and it is possible to optimize the supply rates upstream. Most often we will adjust the opening angle and the opening time of the doors. In special cases, depending on the products processed, one of the parameters may be set in advance and the adjustment will be made during processing on the second parameter. According to a first arrangement of the invention, the installation comprises means for determining the height of the product which have an action on the opening angle of the hatch corresponding to its assignment. According to another arrangement, it includes means for determining the length of the product acting on the opening time of the hatch which corresponds to its allocation.
Selon une forme de réalisation particulière, cette installation comporte un système qui assure la détection de la longueur et/ou de la hauteur des produits, du type cellule à ultrasons ou caméra CCD par exemple. Ce système permet l'adaptation de l'angle et/ou du temps d'ouverture de la trappe qui correspond à l'affectation du produit au moyen de capteurs, magnétiques par exemple, disposés sur le ou les vérins qui commandent son mouvement. Des moyens différents et/ou indépendants peuvent être utilisés pour déterminer la hauteur et la longueur des produits. Ces caractéristiques permettent à la personne ou au matériel automatique qui charge l'installation, en amont, d'adapter les cadences en fonction de la taille des produits.According to a particular embodiment, this installation comprises a system which detects the length and / or the height of the products, of the ultrasonic cell or CCD camera type for example. This system allows the adaptation of the angle and / or the opening time of the hatch which corresponds to the allocation of the product. by means of sensors, magnetic for example, arranged on the jack or jacks which control its movement. Different and / or independent means can be used to determine the height and the length of the products. These characteristics allow the person or the automatic equipment that loads the installation, upstream, to adapt the rates according to the size of the products.
La position de la trappe est gérée de façon automatique en fonction des informations enregistrées par le système de détection pour évacuer chaque produit à un niveau bien déterminé, en fonction de sa caractéristique différenciatrice.The position of the hatch is managed automatically according to the information recorded by the detection system to evacuate each product at a well determined level, according to its differentiating characteristic.
Les moyens de tri permettent notamment le positionnement de bacs de réception sous la ou les trappes d'évacuation en vue de récupérer et de regrouper les produits évacués, par simple gravité. La trappe à position variable réalise une rupture du plan de dépose et de défilement des produits pour leur évacuation par simple modification de leur trajectoire.The sorting means allow in particular the positioning of receiving bins under the evacuation hatch or hatches with a view to recovering and grouping the evacuated products, by simple gravity. The variable position hatch breaks the plan for depositing and scrolling products for their evacuation by simply modifying their trajectory.
Selon un premier mode de réalisation, le convoyeur formant trappe est mobile autour d'un axe perpendiculaire à la direction de convoyage et disposé du côté de son extrémité amont par rapport au sens de défilement des produits. L'ouverture de la trappe est définie par une descente dudit convoyeur.According to a first embodiment, the hatch conveyor is movable about an axis perpendicular to the conveying direction and disposed on the side of its upstream end relative to the direction of travel of the products. The opening of the hatch is defined by a descent of said conveyor.
Selon un second mode de réalisation, le convoyeur en forme de trappe est mobile autour d'un axe perpendiculaire à la direction de convoyage et disposé du côté de son extrémité aval par rapport au sens de défilement des produits. L'ouverture de la trappe est définie par une montée dudit convoyeur.According to a second embodiment, the hatch-shaped conveyor is movable about an axis perpendicular to the conveying direction and disposed on the side of its downstream end relative to the direction of travel of the products. The opening of the hatch is defined by a rise of said conveyor.
Selon un autre mode de réalisation, la trappe d'évacuation est constituée de deux convoyeurs juxtaposés. Le convoyeur amont est mobile autour d'un axe perpendiculaire à la direction de convoyage et disposé du côté de son extrémité amont ; le convoyeur aval est mobile autour d'un axe perpendiculaire à la direction de convoyage et disposé du côté de son extrémité aval. L'ouverture de la trappe, pour l'évacuation du produit, est définie par une descente du convoyeur amont et une montée du convoyeur aval. L'axe de mobilité du convoyeur est de préférence confondu avec l'axe de rotation de l'un de ces tambours d'extrémité. Dans d'autres modes de réalisation, le convoyeur peut se déplacer vers le haut, parallèlement à lui-même ; il peut également pivoter vers le haut ou vers le bas, autour d'un axe parallèle à la direction de convoyage.According to another embodiment, the evacuation hatch consists of two juxtaposed conveyors. The upstream conveyor is movable around an axis perpendicular to the conveying direction and arranged on the side of its upstream end; the downstream conveyor is movable around an axis perpendicular to the direction conveyor and arranged on the side of its downstream end. The opening of the hatch, for the evacuation of the product, is defined by a descent of the upstream conveyor and an ascent of the downstream conveyor. The axis of mobility of the conveyor is preferably coincident with the axis of rotation of one of these end drums. In other embodiments, the conveyor can move upward, parallel to itself; it can also pivot up or down, around an axis parallel to the conveying direction.
Toujours selon l'invention, l'installation de tri comporte une pluralité de trappes, sur la longueur du second système de convoyage, séparées les unes des autres par des convoyeurs plans, fixes, servant de zones tampon. Elle est également munie de moyens de détection de la caractéristique différenciatrice du produit, connectés à des moyens de commande temporisée de l'ouverture de la trappe qui correspond à l'affectation dudit produit, et de moyens de détection des caractéristiques d'encombrement du produit, connectés, d'une part, aux moyens d'adaptation de l'angle d'ouverture et/ou du temps d'ouverture de ladite trappe et, d'autre part, à des moyens d'action sur un système d'approvisionnement automatique, disposé en amont, en vue d'adapter les cadences en fonction des produits traités et des possibilités du système de tri inhérentes.Still according to the invention, the sorting installation comprises a plurality of hatches, along the length of the second conveying system, separated from each other by flat, fixed conveyors, serving as buffer zones. It is also provided with means for detecting the differentiating characteristic of the product, connected to means for timed control of the opening of the hatch which corresponds to the allocation of said product, and with means for detecting the dimensions of the product dimensions. , connected, on the one hand, to the means of adapting the opening angle and / or the opening time of said hatch and, on the other hand, to means of action on a supply system automatic, arranged upstream, in order to adapt the rates according to the products treated and the possibilities of the inherent sorting system.
Selon une autre caractéristique de l'invention, l'installation comporte des carters latéraux sur toute sa longueur. Ces carters assurent la protection des mécanismes et, en s'élevant au-dessus du plan de dépose, permettent surtout la réalisation d'un couloir de convoyage évitant la chute des produits sur les côtés. L'installation peut alors être montée sur un navire et fonctionner indépendamment du roulis et du tangage.According to another characteristic of the invention, the installation comprises lateral casings over its entire length. These casings protect the mechanisms and, by rising above the removal plane, above all allow the creation of a conveyor corridor preventing the products from falling on the sides. The installation can then be mounted on a ship and operate independently of roll and pitch.
Une installation de tri automatique telle que décrite ci-avant peut par exemple permettre le tri de produits selon leur poids. Le système de détection de la caractéristique différenciatrice des produits consiste alors avantageusement en un convoyeur sans fin muni de moyens de détermination du poids des produits, du type pesons ou jauges de contrainte, par exemple.An automatic sorting installation as described above can for example allow sorting of products according to their weight. The detection system differentiating characteristic of the products then advantageously consists of an endless conveyor provided with means for determining the weight of the products, of the load cell or strain gauge type, for example.

On a représenté sur les figures 1 à 3, un premier mode de réalisation de l'installation de tri selon l'invention. Cette installation est constituée d'une succession de convoyeurs sans fin qui définissent un plan 1 de dépose et de défilement sensiblement horizontal. Les différents convoyeurs sont motorisés pour assurer l'entraînement des produits 2 de l'amont vers l'aval, selon la flèche d'orientation 3 et à une vitesse de préférence constante ; ils sont montés sur un bâti support 5 qui n'a pas été représenté pour simplifier la figure.There is shown in Figures 1 to 3, a first embodiment of the sorting installation according to the invention. This installation consists of a succession of endless conveyors which define a plan 1 for placing and scrolling substantially horizontal. The different conveyors are motorized to drive the products 2 from upstream to downstream, according to the orientation arrow 3 and at a speed preferably constant; they are mounted on a support frame 5 which has not been shown to simplify the figure.
L'installation de tri comporte, en amont, un convoyeur sans fin 4, du type tapis accélérateur par exemple, disposé au niveau du poste de décharge. La longueur de ce convoyeur 4 est fonction des caractéristiques de l'installation et/ou des produits 2 que l'on désire trier. Il est destiné à amener les produits, individuellement, jusqu'au convoyeur sans fin 5 qui le jouxte. Ce convoyeur 5 est muni de moyens susceptibles de détecter automatiquement la caractéristique différenciatrice des produits sur la base de laquelle on va réaliser le tri. Cette caractéristique peut être de toute nature telle que le poids, la taille, la couleur ... ; les moyens de détection utilisés sont choisis et adaptés en fonction de cette caractéristique. Dans le cas d'une trieuse pondérale, le convoyeur sans finThe sorting installation comprises, upstream, an endless conveyor 4, of the accelerator belt type for example, disposed at the discharge station. The length of this conveyor 4 is a function of the characteristics of the installation and / or of the products 2 which it is desired to sort. It is intended to bring the products, individually, to the endless conveyor 5 which adjoins it. This conveyor 5 is provided with means capable of automatically detecting the differentiating characteristic of the products on the basis of which the sorting will be carried out. This characteristic can be of any kind such as weight, size, color ...; the detection means used are chosen and adapted according to this characteristic. In the case of a checkweigher, the endless conveyor
5 consiste en un tapis de pesée classique, muni de moyens de détection tels que des jauges de contrainte, ou des pesons à flexion ou compression par exemple. Un convoyeur sans fin 6 peut avantageusement faire suite au convoyeur 5 pour servir de zone tampon ; sa longueur est adaptée pour laisser au matériel de détection le temps d'analyser les informations reçues et de les transmettre au système de tri disposé en aval. Les moyens qui assurent le tri des produits 2 sont constitués de convoyeurs sans fin 7, détaillés figures 2 et 3, associés à des moyens de commande de position en forme de vérins pneumatiques ou hydrauliques 8 double effet. Les convoyeurs 7 sont mobiles autour de l'axe d'articulation 10 qui correspond à l'axe de rotation de leur tambour d'extrémité aval ; cet axe 10 est perpendi¬ culaire à la direction 3 de convoyage.5 consists of a conventional weighing belt, provided with detection means such as strain gauges, or flexion or compression scales for example. An endless conveyor 6 can advantageously follow the conveyor 5 to serve as a buffer zone; its length is adapted to give the detection equipment time to analyze the information received and to transmit it to the sorting system located downstream. The means which ensure the sorting of the products 2 consist of endless conveyors 7, detailed in Figures 2 and 3, associated with position control means in the form of pneumatic or hydraulic cylinders 8 double effect. The conveyors 7 are movable around the hinge axis 10 which corresponds to the axis of rotation of their downstream end drum; this axis 10 is perpendicular to the conveying direction 3.
La manoeuvre de rotation des convoyeurs 7 autour de l'axe 10 est obtenue au moyen de deux vérins 8 disposés latéralement. Le corps des vérins 8 est solidarisé au châssis 11 de l'installation ; leur tige est fixée sur la structure du convoyeur 7 par l'intermédiaire d'une patte 12 rapportée. En position inactive, le convoyeur 7 se situe dans le plan 1 de convoyage et il permet la poursuite du défilement des produits ; sa position active est obtenue par une extension de la tige des vérins 8 pour réaliser un pivotement vers le haut. Ce basculement créé une ouverture dans le plan de convoyage qui va permettre la chute du ou des produits 2, par simple gravité.The rotation of the conveyors 7 around the axis 10 is obtained by means of two jacks 8 arranged laterally. The body of the jacks 8 is secured to the frame 11 of the installation; their rod is fixed to the structure of the conveyor 7 by means of an attached tab 12. In the inactive position, the conveyor 7 is located in the conveying plane 1 and it allows the products to continue running; its active position is obtained by an extension of the rod of the jacks 8 to achieve pivot up. This tilting creates an opening in the conveying plane which will allow the fall of the product or products 2, by simple gravity.
Le nombre de convoyeurs mobiles 7 dans l'installation de tri est fonction du nombre de classes de produits que l'on peut obtenir, en liaison notamment avec les moyens de détection associés au convoyeur 5. De préférence, les convoyeurs mobiles 7 sont séparés les uns des autres par des convoyeurs sans fin 13, fixes, servant de zone tampon. L'installation de tri comporte des moyens électroniques et informatiques, non représentés, qui permettent la gestion de la manoeuvre des différents convoyeurs mobiles 7 en fonction des informations reçues par le système de détection du convoyeur 5. Ces moyens de gestion sont connectés aux vérins 8 de chaque convoyeur mobile ; ils commandent le basculement temporisé de la trappe 7 qui correspond à l'endroit où l'on désire évacuer le produit détecté.The number of mobile conveyors 7 in the sorting installation depends on the number of product classes that can be obtained, in particular with the detection means associated with the conveyor 5. Preferably, the mobile conveyors 7 are separated from each other by endless conveyors 13, fixed, serving as a buffer zone. The sorting installation includes electronic and computer means, not shown, which allow the management of the operation of the various mobile conveyors 7 as a function of the information received by the detection system of the conveyor 5. These management means are connected to the jacks 8 of each mobile conveyor; they control the timed tilting of the hatch 7 which corresponds to the place where one wishes to evacuate the detected product.
Pour une trieuse pondérale, au cours du fonctionnement fje l'installation, le poids du produit 2 est enregistré lors de son passage sur le convoyeur de pesée 5. Dès sa sortie dudit convoyeur 5, son affectation est connue ; étant donné la vitesse constante du défilement des produits, les moyens de gestion vont pouvoir commander l'ouverture de la trappe correspondante, juste avant l'arrivée du produit. Des bacs de récupération 14 sont disposés sous chaque trappe pour récupérer les produits triés. Les moyens de gestion commandent la fermeture de la trappe 7 juste après la chute du produit afin d'assurer, le cas échéant, le défilement des produits ultérieurs.For a checkweigher, during operation fj e installation, the weight of the product 2 is recorded during its passage on the weighing conveyor 5. As soon as it leaves said conveyor 5, its assignment is known; given the constant speed of movement of the products, the management means will be able to control the opening of the corresponding hatch, just before the arrival of the product. Recovery bins 14 are arranged under each hatch to recover the sorted products. The management means control the closing of the hatch 7 just after the fall of the product in order to ensure, if necessary, the scrolling of the subsequent products.
L'installation est en outre munie de moyens de détection de l'encombrement général du produit, et en particulier de sa longueur et de sa hauteur, pour adapter l'angle d'ouverture et le temps d'ouverture d.es trappes en fonction de ces caractéristiques.The installation is also provided with means for detecting the overall size of the product, and in particular its length and height, to adapt the opening angle and the opening time of the hatches as a function of these characteristics.
Ces moyens de détection peuvent consister en un système 15, du type cellule à ultra-sons ou caméra CCD, par exemple, disposé à l'entrée du convoyeur 5. La détection de la hauteur du produit est utilisée par le système de gestion pour régler l'angle d'ouverture .a du convoyeurThese detection means may consist of a system 15, of the ultrasonic cell or CCD camera type, for example, arranged at the entrance to the conveyor 5. Detection of the height of the product is used by the management system to adjust the opening angle .a of the conveyor
7 correspondant. Le système 15 balaie toute la largeur du convoyeur 5 et permet la détection du passage des extrémités aval et amont des produits. La vitesse de défilement étant constante, le laps de temps écoulé entre l'enregistrement des deux détections permet le calcul de la longueur du produit. Connaissant cette longueur, le système de gestion de l'installation adapte le temps d'ouverture nécessaire de la trappe correspondante. Le contrôle de l'angle d'ouverture et du temps d'ouverture peut se faire par l'intermédiaire de capteurs, magnétiques par exemple disposés sur les vérins 8. Ces capteurs commandent la course de la tige des vérins et le temps de va et vient.7 correspondent. The system 15 scans the entire width of the conveyor 5 and allows the detection of the passage of the downstream and upstream ends of the products. As the scrolling speed is constant, the period of time between the recording of the two detections allows the length of the product to be calculated. Knowing this length, the installation management system adapts the necessary opening time of the corresponding hatch. The opening angle and the opening time can be controlled by sensors, magnetic for example placed on the jacks 8. These sensors control the stroke of the cylinder rod and the travel time and come.
On remarque sur les figures 2 et 3 que la même trappe 7 adapte son angle d'ouverture _a en fonction du produit 2 qui va être évacué ; son temps d'ouverture à l'angle maximum est ajusté de la même façon.Note in Figures 2 and 3 that the same hatch 7 adapts its opening angle _a depending on the product 2 which will be removed; its opening time at the maximum angle is adjusted in the same way.
Cette caractéristique permet d'adapter l'ouverture de la trappe au produit évacué. On limite ainsi au maximum les pertes de temps liées aux trop grandes ou trop longues ouvertures et il est ainsi possible d'optimiser les cadences d' approvisionnemet, en amont, pour rendre l'installation plus performante.This characteristic makes it possible to adapt the opening of the hatch to the product discharged. This minimizes the loss of time associated with too large or too long openings and it is thus possible to optimize the supply rates, upstream, to make the installation more efficient.
Si cet approvisionnement est réalisé manuellement, l'opérateur analyse le fonctionnement du système de tri et adapte sa cadence de décharge en fonction.If this supply is carried out manually, the operator analyzes the operation of the sorting system and adapts its discharge rate accordingly.
Dans d'autres cas, cet approvisionnement peut être réalisé au moyen d'un dispositif automatique 16 disposé devant le tapis accélérateur 4. La cadence de ce dispositif d'approvisionnement est alors avantageusement commandée par le système de gestion de l'installation de tri. Par exemple, le système 15 qui détecte l'encombrement des produits, peut agir sur ce dispositif, par le biais d'un logiciel adapté, en fonction des informations qu'elle recueille, lesquelles informations sont utilisées par le système de gestion pour optimiser l'ouverture des trappes de la façon décrite ci-avant.In other cases, this supply can be achieved by means of an automatic device 16 disposed in front of the accelerator belt 4. The rate of this supply device is then advantageously controlled by the management system of the sorting installation. For example, the system 15 which detects the congestion of the products, can act on this device, by means of suitable software, as a function of the information it collects, which information is used by the management system to optimize the opening hatches as described above.
On a représenté sur les figures 4 et 5 une installation de tri dont le fonctionnement général est identique. On y retrouve le convoyeur de décharge 4, le c convoyeur 5 muni des moyens de détection 15 de la longueur et hauteur des produits, suivi par le convoyeur fixe tamponThere is shown in Figures 4 and 5 a sorting installation whose general operation is identical. There we find the discharge conveyor 4, the c conveyor 5 provided with means 15 for detecting the length and height of the products, followed by the fixed buffer conveyor
6. Les moyens assurant le tri des produits consistent également en un système de trappes qui réalisent des ruptures du plan de convoyage selon les produits que l'on désire évacuer.6. The means ensuring the sorting of the products also consist of a system of hatches which produce breaks in the conveying plane according to the products which it is desired to evacuate.
Dans ce mode de réalisation, le ou les convoyeurs 7' qui réalisent les trappes d'évacuation sont mobiles autour d'un axe 17 perpendiculaire à la direction de convoyage 3 et disposé du côté de son extrémité amont. L'ouverture de la trappe pour l'évacuation du produit, est alors définie par une descente dudit convoyeur, tel qu'on l'a représenté sur la figure 5. Le convoyeur 7' joue le rôle d'une rampe permettant d'adoucir la chute des produits dans les bacs 14 de récupération. La figure 6 montre un autre mode de réalisation possible du système de tri selon l'invention dans lequel la trappe 7" est constituée de deux convoyeurs mobiles 18 et 19 juxtaposés. Ces convoyeurs 18 et 19 sont commandés en basculement inverse afin de limiter le temps d'écartement nécessaire à l'obtention de l'angle d'ouverture _a. Le convoyeur amont 18 est mobile autour de l'axe 20 perpendiculaire à la direction de convoyage et disposé du côté de son extrémité amont. Le convoyeur aval 19 est mobile vers le haut par rotation autour de l'axe 21 perpendiculaire à la direction de convoyage et disposé du côté de son extrémité aval. Selon une forme de réalisation préférée, ces deux convoyeurs 18 et 19 sont manoeuvres par une biellette 22 elle-même commandée par un vérin hydraulique ou pneumatique 23. La zone centrale de la biellette 22 est solidarisée au châssisIn this embodiment, the conveyor (s) 7 ′ which produce the evacuation hatches are movable about an axis 17 perpendicular to the conveying direction 3 and arranged on the side of its upstream end. The opening of the hatch for the evacuation of the product is then defined by a descent of said conveyor, as shown in FIG. 5. The conveyor 7 ′ plays the role of a ramp making it possible to soften the fall of the products in the recovery trays 14. FIG. 6 shows another possible embodiment of the sorting system according to the invention in which the hatch 7 "is made up of two movable conveyors 18 and 19 juxtaposed. These conveyors 18 and 19 are controlled in reverse tilting in order to limit the time of spacing necessary to obtain the opening angle _a. The upstream conveyor 18 is movable around the axis 20 perpendicular to the conveying direction and arranged on the side of its upstream end. The downstream conveyor 19 is movable upwards by rotation about the axis 21 perpendicular to the conveying direction and arranged on the side of its downstream end. According to a preferred embodiment, these two conveyors 18 and 19 are maneuvered by a connecting rod 22 itself controlled by a hydraulic or pneumatic cylinder 23. The central area of the link 22 is secured to the chassis
24 par l'intermédiaire d'un axe de rotation horizontal24 via a horizontal axis of rotation
25 et ses extrémités sont respectivement solidaires des zones centrales des convoyeurs 18 et 19 par l'intermédiaire d'axes 26 et 27 qui se déplacent dans des lumières oblongues 28 et 29. On comprend bien que l'action du vérin25 and its ends are respectively secured to the central zones of the conveyors 18 and 19 via axes 26 and 27 which move in oblong slots 28 and 29. It is easy to understand that the action of the jack
23 sur la biellette 22 réalise le basculement simultané des convoyeurs 18 et 19 autour de leurs axes de rotation respectifs 20 et 21 pour réaliser l'ouverture ou la fermeture de la trappe 7".23 on the link 22 performs the simultaneous tilting of the conveyors 18 and 19 around their respective axes of rotation 20 and 21 to open or close the hatch 7 ".
La gestion de ce type de trappe 7" est identique à celle prévue pour les trappes 7 et 7' décrites ci-avant, notamment pour l'adaptation de l'angle a_ et du temps d'ouverture. Dans ce dernier exemple de réalisation on peut obtenir l'angle d'ouverture _a dans un temps environ trois fois plus rapide, ce qui permet d'augmenter encore les cadences. Ces trappes 7" peuvent être disposées les unes derrière les autres ou être séparées par des convoyeurs tampon fixes 13.The management of this type of hatch 7 "is identical to that provided for the hatches 7 and 7 'described above, in particular for the adaptation of the angle a_ and the opening time. In this last embodiment example, can obtain the opening angle _a in about three times faster, which makes it possible to further increase the rates. These 7 "hatches can be arranged one behind the other or be separated by fixed buffer conveyors 13.
Les dimensions de l'installation sont essentiellement liées au type de produit que l'on désire trier et au nombre de groupes envisagés. Les convoyeurs sans fin utilisés sont également adaptés en fonction du produit transporté ; ils pourront consister en des convoyeurs à bande, à chaîne, à barrette ... Leur motorisation est réalisée par les moyens classiques liés à cette technique.The dimensions of the installation are essentially linked to the type of product to be sorted and to the number of groups envisaged. The endless conveyors used are also adapted according to the product transported; they may consist of conveyor belts, chains, bars, etc. Their motorization is carried out by conventional means associated with this technique.
Pour la fabrication, il peut être avantageux de réaliser des modules de tri constitués d'une trappe mobile 7s 7* f 7" munie des moyens 8 de commande de position, associée à un convoyeur fixe 13. Il est alors possible d'adapter autant de modules qu'on le désire, mis bout à bout, selon l'installation commandée.For manufacturing, it may be advantageous to produce sorting modules consisting of a movable hatch 7 s 7 * f 7 "provided with position control means 8, associated with a fixed conveyor 13. It is then possible to adapt as many modules as desired, placed end to end, depending on the installation ordered.
On comprend bien qu'une telle installation de tri peut fonctionner sans aucun problème quels que soient les dimensions ou les aspects des produits traités. Elle limite les traumatismes ou les chocs importants et peut être utilisée à des cadences assez rapides, de l'ordre de trois produits par seconde. Les installations décrites ci-avant réalisent l'évacuation des produits par le bas, sous le plan de dépose et de défilement ; il est ainsi possible de travailler des deux côtés du tapis. En outre, il est également possible d'adapter des guides ou carters latéraux sur toute la longueur des convoyeurs, pour assurer la protection des mécanismes et éviter la chute des produits sur les côtés. Ces carters peuvent être montés soit sur le châssis de l'installation, soit directement sur les côtés de chaque convoyeur en vue de suivre notamment le mouvement des convoyeurs mobiles. Leur hauteur dépend principalement du produit traité et de la place disponible ; ils permettent la réalisation d'un plan de dépose en forme de couloir. Cette caractéristique présente l'avantage de permettre l'utilisation d'une telle installation sur un bateau par exemple, pour le traitement des poissons. Les installations de l'état de la technique pouvaient difficilement être utilisées dans de telles applications, en raison du tangage et du roulis.It will be understood that such a sorting installation can function without any problem whatever the dimensions or the aspects of the products treated. It limits trauma or significant shock and can be used at fairly rapid rates, of the order of three products per second. The art facilities described above realize the discharge of products from the bottom in terms of deposits and scrolling; it is thus possible to work on both sides of the carpet. In addition, it is also possible to adapt lateral guides or casings over the entire length of the conveyors, to ensure the protection of the mechanisms and avoid the fall of the products on the sides. These casings can be mounted either on the installation chassis, or directly on the sides of each conveyor in order to follow in particular the movement of the mobile conveyors. Their height depends mainly on the product treated and the space available; they allow the creation of a corridor-shaped deposit plan. This characteristic has the advantage of allowing the use of such an installation on a boat for example, for the treatment of fish. The state-of-the-art facilities could hardly be used in such applications, due to pitch and roll.
