Description

Procédé et dispositif pour ouvrir par la zone médiane de leur corps, vider et aplatir des récipients métalliques ou composites hermétiquement fermésMethod and device for opening through the middle area of their body, emptying and flattening hermetically sealed metal or composite containers
La présente invention a pour objet un procédé et un dispositif pour ouvrir, vider et aplatir en une seule opération des récipients métalliques ou composites hermétiquement fermés, de préférence cylindriques. On sait que l'ouverture de ce genre de récipients, en particulier des boîtes de conserves, est traditionnellement effectuée par découpage d'un des fonds ou couvercles autour des sertis, ce qui est lent et dangereux, car les bords des couvercles ou des sertis devenus coupants risquent de blesser l'opérateur.The subject of the present invention is a method and a device for opening, emptying and flattening in a single operation hermetically closed metal or composite containers, preferably cylindrical. We know that the opening of this kind of container, in particular cans, is traditionally carried out by cutting one of the bottoms or lids around the settings, which is slow and dangerous, because the edges of the covers or settings sharp edges can injure the operator.
De plus, les récipients vides devenus encombrants sont jusqu'à présent évacués, soit par despoubelles ou conteneurs volumineux, soit repris pour être écrasés dans des presses à déchets ou des broyeurs onéreux et qui nécessitent des manutentions, du temps et de l'énergie.In addition, empty containers that have become bulky have been evacuated up to now, either by bins or bulky containers, or taken up to be crushed in waste presses or expensive shredders and which require handling, time and energy.
La présente invention a pour but d'éliminer ces inconvénients en proposant un procédé et un dispositif permettant d'exécuter en une seule opération l'ouverture, le vidage et l'écrasement des récipients, sans aucun risque de blessures pour l'utilisateur, ce dispositif pouvant aussi bien être utilisé par des particuliers, des artisans, des industriels, que par des collectivités telles que des restaurants. Conformément à l'invention, le procédé est caractérisé en ce qu'on sectionne partiellement les récipients dans la zone médiane de leur corps en réservant entre leurs deux moitiés une languette de retenue, on déforme ces deux moitiés tout en les ouvrant vers le bas de façon à les vider avant de les écraser, et on éjecte les récipients écrasés après que leurs contenus soient recueillis dans un réceptacle.The object of the present invention is to eliminate these drawbacks by proposing a method and a device making it possible to execute, in a single operation, the opening, emptying and crushing of the containers, without any risk of injury to the user. device that can be used by individuals, artisans, manufacturers, as well as by communities such as restaurants. According to the invention, the method is characterized in that the containers are partially sectioned in the median zone of their body by reserving a retaining tab between their two halves, these two halves are deformed while opening them downwards. way to empty them before putting them crush, and the crushed containers are ejected after their contents are collected in a receptacle.
Ainsi, contrairement à ce qui s'est toujours pratiqué jusqu'à présent, l'invention prévoit d'ouvrir les récipients non plus par l'un de leurs fonds, mais par la zone médiane de leur corps.Thus, contrary to what has always been practiced until now, the invention provides for opening the containers no longer by one of their bottoms, but by the median zone of their body.
Suivant l'invention, le dispositif pour la mise en oeuvre de ce procédé est caractérisé en ce qu'il comprend, montés dans un bâti support fixe : a) une trémie, percée à sa base d'une ouverture et de lumières délimitant des plans inclinés convergents et verticaux qui débouchent dans cette ouverture; b) un moyen d'alimentation de la trémie en récipients par l'intermédiaire d'une écluse, par exemple une. goulotte, de telle sorte que chaque récipient puisse prendre appui successivement par ses extrémités sur les parois inclinées de la trémie et au-dessus de ladite ouverture; c) un outil muni d'un couteau (x) au moins de découpe du récipient, monté dans le bâti de manière à pouvoir être déplacé contre des récipients successifs et équipé de moyens d'entraînement, le couteau ayant un contour s'adaptant au diamètre des récipients et étant positionné de manière à sectionner en partie ceux-ci transversalement dans la zone médiane de leur corps ; d) et des moyens pour ouvrir puis aplatir les récipients après leur découpe par le couteau tout en provoquant leur vidage dans un réceptacle placé sous la trémie.According to the invention, the device for implementing this method is characterized in that it comprises, mounted in a fixed support frame: a) a hopper, pierced at its base with an opening and openings delimiting planes converging and vertical inclines which open into this opening; b) a means for feeding the hopper into containers via a lock, for example one. chute, so that each container can bear successively at its ends on the inclined walls of the hopper and above said opening; c) a tool provided with a knife (x) at least for cutting the container, mounted in the frame so as to be able to be moved against successive containers and equipped with drive means, the knife having a contour adapting to the diameter of the containers and being positioned so as to partially cut them transversely in the median zone of their body; d) and means for opening and then flattening the containers after cutting them with the knife while causing them to be emptied into a receptacle placed under the hopper.
Ainsi, le ou les couteaux (x) de sectionnement des récipients se déplaçant à l'intérieur du bâti du dispositif, hors de portée des mains ee l'utilisateur, tout risque de blessure de celui-ci est écarté.Thus, the knife (s) for sectioning the containers moving inside the frame of the device, out of reach of the hands ee the user, any risk of injury to him is eliminated.
De plus, l'aplatissage ou l'écrasement des récipients consécutif à leur vidage est exécuté sans manutention particulière et sans risque d'accident pour l'utilisateur.In addition, the flattening or crushing of the containers following their emptying is carried out without special handling and without risk of accident for the user.
Enfin, l'écrasement des récipients après leur vidage résoud les problèmes d'encombrement rencontrés jusqu'à présent, tout en supprimant la contrainte de disposer le cas échéant de presses à déchets ou de broyeurs coûteux.Finally, the crushing of the containers after their emptying solves the problems of space encountered up to now, while eliminating the constraint of having, where appropriate, waste presses or expensive shredders.

At its upper part, the knife 11 is provided with a non-cutting dish 15, separating the two cutting sections, so as to be able to leave a retaining tab together of the two halves of the container 7 after cutting the latter. In the example shown in Figures 1 to 3, the knife actuation means 11 comprise a manual lever system 16 articulated, on the one hand on an arm 17 mounted in the central part of the frame 1, and on the other hand at 18 on the frame 1. This manual system can be replaced by any other equivalent means, for example one or more mechanical electrical, pneumatic or hydraulic systems, particularly indicated if the device is to be used on an industrial scale or by communities. The device also includes an ejector 19 disposed at the bottom of the hopper 2 and its opening 3, and capable of sliding horizontally therein in order to eject the container 7 completely flattened and after raising the knife 11. The ejector 19 can be, as the case may be, provided with one or more knife (s) 21 arranged to be able to contribute to the cutting and opening of the container 7 simultaneously with the actuation of the knife 11, the ejector 19 being for this purpose advanced in the opening 3, in synchronization with the movement of the pestle 9.
La goulotte ou tapis 6 d'approvisionnement en récipients 7 à ouvrir peut servir de table d'- accumulation, tandis que l'écluse 8 est réglable selon le format des récipients, en ne permettant le passage vers l'intérieur du bâti ou carter 1 de sécurité que d'un récipient à la fois. Le couteau 11 est agencé pour pouvoir pratiquer une découpe latérale circulaire sur la plus grande partie du périmètre. du récipient 7, en conservant une languette non découpée à l'endroit du périmètre non découpé correspondant au plat 15.The chute or mat 6 for supplying receptacles 7 to be opened can serve as an accumulation table, while the lock 8 is adjustable according to the format of the receptacles, not allowing passage towards the interior of the frame or casing 1 only one container at a time. The knife 11 is arranged so as to be able to make a circular lateral cut over the greater part of the perimeter. of the container 7, keeping an uncut tab at the location of the uncut perimeter corresponding to the dish 15.
La trémie 2 est formée, outre les deux parois 5, de deux parois latérales verticales 20 dans lesquelles sont ajourées les lumières 4, l'ouverture 3 s'étendant sur toute la longueur des parois inclinées 5.The hopper 2 is formed, in addition to the two walls 5, of two vertical side walls 20 in which the openings 4 are perforated, the opening 3 extending over the entire length of the inclined walls 5.
Le cycle de fonctionnement de ce dispositif mettant en oeuvre le procédé visé par l'invention est le suivant (Figures 4 et 5). Figures 4A et 5A : L'écluse 8 ayant été relevée pour autoriser l'introduction d'un récipient 7 dans la trémie 2 entre les guides 30a-30d en appui sur les parois inclinées 5, puis refermée pour maintenir les récipients suivants 7 en attente, l'utilisateur actionne le levier 16 pour abaisser le pilon 9, dont le couteau 11 vient s'appliquer sur la zone médiane du récipient 7 qu'il sectionne sur un peu plus de la moitié de sa circonférence. Pendant ce temps, l'éjecteur 19 est maintenu en dehors de la trémie 2, en position escamotée.The operating cycle of this device implementing the process targeted by the invention is as follows (Figures 4 and 5). Figures 4A and 5A: The lock 8 having been raised to allow the introduction of a container 7 into the hopper 2 between the guides 30a-30d resting on the inclined walls 5, then closed to keep the following containers 7 on standby , the user actuates the lever 16 to lower the pestle 9, the knife 11 of which is applied to the central zone of the container 7 which it cuts over a little more than half of its circumference. During this time, the ejector 19 is kept outside of the hopper 2, in the retracted position.
Figures 4B et 5B : Le couteau 11 restant dans sa position, l'éjecteur 19 est avancé vers le récipient 7 et son ou ses couteau(x) 21 sectionne la partie inférieure du récipient 7 non découpée par le couteau 11. Puis l' éjecteur 19 et son ou ses couteau(x) 21 sont escamotés jusqu'à leur position initiale, tout en contribuant à écarter en deux parties le récipient 7 qui s'ouvre. Figures 4C et 5C : On continue à abaisser le pilon 9 et son couteau 11 vers le fond de la trémie 2, de sorte que le pilon 9 déforme le récipient 7 dont les deux moitiés ne sont plus retenues que par une languette 10 et se déforment progressivement, après quoi le contenu du récipient 7 se vide dans le réceptacle 13 par l'ouverture 3 (Figures 4D et 5D).Figures 4B and 5B: The knife 11 remaining in its position, the ejector 19 is advanced towards the container 7 and its knife (s) 21 cuts the lower part of the container 7 not cut by the knife 11. Then the ejector 19 and his knife (s) 21 are retracted to their initial position, while helping to separate the container 7 which opens into two parts. Figures 4C and 5C: We continue to lower the pestle 9 and its knife 11 towards the bottom of the hopper 2, so that the pestle 9 deforms the container 7, the two halves of which are retained only by a tongue 10 and are deformed gradually, after which the content of the container 7 empties into the receptacle 13 through the opening 3 (Figures 4D and 5D).
En fin de descente du pilon 9, celui-ci est presque complètement engagé sur les parois 5 grâce à son profil complémentaire de celui desdites parois, en écrasant contre celles-ci le récipient (Figures 4E et 5E).At the end of the descent of the pestle 9, it is almost completely engaged on the walls 5 thanks to its profile complementary to that of said walls, by crushing against them the container (Figures 4E and 5E).
Durant la déformation et l'écrasement du récipient, les deux parties de celui-ci restent maintenues solidaires par la languette centrale non découpée 10.During the deformation and the crushing of the container, the two parts of the latter remain held together by the uncut central tongue 10.
Puis l'opérateur relève l'outil 9 en faisant basculer le levier 16, tandis qu'en synchronisation avec ce relèvement de l'outil 9 (Figures 4E et 5F), l'éjecteur 19 est avancé et pousse le récipient 7 écrasé par les lumières (4) vers un réceptacle de récupération non représenté, extérieur au bâti 1. Le pilon 9 est ramené jusqu'à sa position initiale, permettant l'admission automatique par l'écluse 8 d'un nouveau récipient 7 pour un nouveau cycle de travail. Lorsque le dispositif est utilisé pour l'ouverture de boîtes de conserves, et bien que seuls les couteaux 11, 21 puissent venir en contact très limité avec le contenu des boites, au moins les parois 5 et la base du pilon 9 sont réalisés en des matériaux dits "alimentaires".Then the operator raises the tool 9 by tilting the lever 16, while in synchronization with this raising of the tool 9 (Figures 4E and 5F), the ejector 19 is advanced and pushes the container 7 crushed by the lights (4) towards a not shown recovery receptacle, outside the frame 1. The pestle 9 is brought back to its initial position, allowing automatic admission by the lock 8 of a new container 7 for a new work cycle. When the device is used for the opening of cans, and although only the knives 11, 21 can come into very limited contact with the contents of the cans, at least the walls 5 and the base of the pestle 9 are produced in so-called "food" materials.
Le couteau inférieur 21 pourrait être supprimé et remplacé par tout autre élément équivalent permettant d'achever l'ouverture des récipients 7 en deux moitiés pour permettre leur vidage. Les récipients peuvent aussi ne pas être cylindriques, et le (ou les) couteau(x) ont alors un contour adapté aux récipients, par exemple oblique pour des récipients parallélépipédiques. Suivant une seconde forme de réalisation de l'invention (Figures 7 et 8), les parois 5 sont articulées autour d'axes horizontaux 22 (également visibles aux Figures 4 et 5 ), et sont reliées par une tringle (non représentée) au levier 16, pour assurer leur remontée à leur position initiale simultanément à la remontée du pilon 30, après éjection d'un récipient aplati. Ce système de tringle de liaison est connu en soi et n'a pas été représenté pour simplifier le dessin. Ainsi, lorsque le pilon 30 s'approche d'un récipient 7, puis vient au contact de celui-ci et commence à l'ouvrir par son couteau 31, la pression exercée sur les parois 5 les fait basculer autour des axes 22, et ces parois parviennent ainsi jusqu'à une position pratiquement horizontale, où elles viennent s'appuyer contre la base de la trémie 2. Bien entendu, pour permettre ce basculement, les extrémités supérieures des parois 5 sont tronquées par rapport aux parois visibles aux Figures 1 à 3. Ainsi, le récipient est aplati entre les parois 5 et la surface inférieure du pilon 30.The lower knife 21 could be eliminated and replaced by any other equivalent element making it possible to complete the opening of the containers 7 in two halves to allow their emptying. The containers may also not be cylindrical, and the knife (s) then have a contour adapted to the containers, for example oblique for rectangular containers. According to a second embodiment of the invention (Figures 7 and 8), the walls 5 are articulated around horizontal axes 22 (also visible in Figures 4 and 5), and are connected by a rod (not shown) to the lever 16, to ensure their ascent to their initial position simultaneously with the ascent of the pestle 30, after ejection of a flattened container. This connecting rod system is known per se and has not been shown to simplify the drawing. Thus, when the pestle 30 approaches a container 7, then comes into contact with the latter and begins to open it with its knife 31, the pressure exerted on the walls 5 causes them to tilt around the axes 22, and these walls thus reach a practically horizontal position, where they come to rest against the base of the hopper 2. Of course, to allow this tilting, the upper ends of the walls 5 are truncated relative to the walls visible in Figures 1 to 3. Thus, the container is flattened between the walls 5 and the lower surface of the pestle 30.
L'éjecteur 35 est muni d'un couteau 36 et relié par un élément 37 au système de commande de l'outil 30 (levier 16). La séquence A,B,C,D, E, illustre les phases successives de l'ouverture, de l'aplatissement et du vidage d'un récipient 7. Dans la position A, le couteau 31 parvient au contact avec le récipient 7, les volets ou parois articulés 32 étant relevés. Dans la phase B, s'exécute l'ouverture du récipient 7 par les couteaux 31 et 36, puis la force exercée par l'outil 30 sur les deux moitiés du récipient 7 est transmise aux parois articulées 32 qui s'écartent l'une de l'autre et basculent autour des axes 34, tandis que le récipient se vide. Puis (phases C-D), le récipient 7 est progressivement aplati entre les volets 32 et l'outil 30, les volets 32 sont complètement rabattus autour des axes 34 et le récipient 7 est complètement aplati entre lesdits volets 32 et l ' outil 30, et enfin dans la phase E, l'éjecteur 35 éjecte le récipient aplati 7.The ejector 35 is provided with a knife 36 and connected by an element 37 to the tool control system 30 (lever 16). The sequence A, B, C, D, E, illustrates the successive phases of opening, flattening and emptying of a container 7. In position A, the knife 31 comes into contact with the container 7, the flaps or articulated walls 32 being raised. In phase B, the opening of the container 7 is carried out by the knives 31 and 36, then the force exerted by the tool 30 on the two halves of the container 7 is transmitted to the articulated walls 32 which separate one on the other and tilt around the axes 34, while the container is emptying. Then (phases CD), the container 7 is progressively flattened between the flaps 32 and the tool 30, the flaps 32 are completely folded down around the axes 34 and the container 7 is completely flattened between said flaps 32 and the tool 30, and finally in phase E, the ejector 35 ejects the flattened container 7.
Dans la troisième forme de réalisation illustrée aux Figures 9 et 10, l'outil 38 est monté de manière à pouvoir être déplacé horizontalement (alors que l'outil des deux réalisations précédentes se déplace verticalement), et est fixé à un support 39 articulé en 41 sur un levier 42 de commande, lui-même articulé autour d'un axe horizontal 43. L'extrémité du levier 42 est articulée autour d'un axe horizontal 44 sur la partie terminale d'un éjecteur 45 constitué de deux bras 46 équipés chacun d'un couteau terminal 47.In the third embodiment illustrated in Figures 9 and 10, the tool 38 is mounted so that it can be moved horizontally (while the tool of the two previous embodiments moves vertically), and is fixed to a support 39 articulated in 41 on a control lever 42, itself articulated around a horizontal axis 43. The end of the lever 42 is articulated around a horizontal axis 44 on the terminal part of an ejector 45 consisting of two arms 46 each equipped with a terminal knife 47.
Dans la phase initiale A, le récipient 7 tombé de la goulotte 6 est maintenu entre le couteau 39a de l'outil 38 et les couteaux 47. Lorsque l'on fait basculer le levier 42 autour de l'axe 43 dans le sens anti-horaire (flèche sur la Figure 10B), ce basculement provoque l'avance de l'outil 38 qui ouvre par son milieu le récipient 7, et le recul simultané de l'éjecteur 45 dont les couteaux 47 achèvent l'ouverture du récipient. Dans l'étape B, ce dernier se trouve poussé par l'outil 38 contre la paroi inclinée 5, tandis que les deux bras 46 de l'éjecteur 45 s'ouvrent et que le récipient 7 se vide. Dans la phase C, l'outil 38 a poursuivi son avance, tandis que les bras 46 de l'éjecteur 45 continuent de s'écarter et de reculer, et le récipient 7 est aplati entre l'outil 38 et la paroi 5. L'éjecteur 45 est complètement escamoté, le levier de commande 42 étant dans sa position inclinée maximum. En phase finale D, le levier 42 bascule en sens inverse et ramène progressivement l'outil 38 à sa position initiale, et que le récipient 7 complètement aplati glisse par l'ouverture 4 d'évacuation, tandis que le contenu du récipient est vidé dans le réceptacle 13. In the initial phase A, the container 7 which has fallen from the chute 6 is held between the knife 39a of the tool 38 and the knives 47. When the lever 42 is tilted around the axis 43 in the anti-direction clockwise (arrow in FIG. 10B), this tilting causes the advance of the tool 38 which opens the container 7 through its middle, and the simultaneous retraction of the ejector 45 whose knives 47 complete the opening of the container. In step B, the latter is pushed by the tool 38 against the inclined wall 5, while the two arms 46 of the ejector 45 open and the container 7 is emptied. In phase C, the tool 38 continued to advance, while the arms 46 of the ejector 45 continue to move apart and move back, and the container 7 is flattened between the tool 38 and the wall 5. L ejector 45 is completely retracted, the control lever 42 being in its maximum inclined position. In the final phase D, the lever 42 switches in the opposite direction and gradually brings the tool 38 back to its initial position, and the completely flat container 7 slides through the discharge opening 4, while the content of the container is emptied into receptacle 13.
