Domaine techniqueTechnical area

La présente invention est relative à un procédé pour le déversement d'un contenu d'un conteneur mis en oeuvre par un basculeur de conteneur pour véhicule de collecte, et notamment de collecte des déchets, prévu pour assurer le déchargement du contenu d'un conteneur dans une benne reçue à l'arrière d'un véhicule de collecte, ainsi qu'un véhicule de collecte équipée d'un tel basculeur.The present invention relates to a method for dumping the contents of a container implemented by a container tipper for a collection vehicle, and in particular for collecting waste, provided to ensure the unloading of the contents of a container. in a dumpster received at the rear of a collection vehicle, as well as a collection vehicle equipped with such a tipper.

Technique antérieurePrior technique

De façon connue, un véhicule de collecte, employé notamment pour le ramassage de déchets, comporte une benne positionnée à l'arrière dudit véhicule, et est avantageusement équipé d'un basculeur, configuré pour saisir un conteneur, au niveau d'une lèvre entourant l'ouverture de déversement du conteneur, et pour basculer ledit conteneur par rapport à la benne, de sorte à entraîner le déversement du contenu du conteneur, sous l'effet de la gravité, dans ladite benne au travers d'une ouverture ménagée dans ladite benne.In known manner, a collection vehicle, used in particular for collecting waste, comprises a dumpster positioned at the rear of said vehicle, and is advantageously equipped with a tipper, configured to grasp a container, at the level of a lip surrounding the dumping opening of the container, and to tip said container relative to the dumpster, so as to cause the dumping of the contents of the container, under the effect of gravity, into the said dumpster through an opening provided in the said dumpster.

Un tel basculeur comporte généralement un support, fixé sur une partie du véhicule de collecte, et notamment sur le châssis dudit véhicule, et un bras, recevant au niveau d'une de ses extrémités un moyen de préhension d'au moins un conteneur, ledit bras étant articulé par rapport au support, de sorte que ledit bras effectue un mouvement par rapport au support tel que le conteneur passe d'une position sensiblement verticale en appui sur le sol, à une position de déversement, dans laquelle l'ouverture de déversement du conteneur se retrouve au-dessus de ladite benne et le conteneur se retrouve dans une position telle que son contenu tombe dans la benne, au travers de son ouverture, entraîné par la gravité.Such a tilter generally comprises a support, fixed to a part of the collection vehicle, and in particular to the chassis of said vehicle, and an arm, receiving at one of its ends a means of gripping at least one container, said arm being articulated with respect to the support, so that said arm performs a movement with respect to the support such that the container passes from a substantially vertical position resting on the ground, to a dumping position, in which the dumping opening of the container is found above said bucket and the container is found in a position such that its contents fall into the bucket, through its opening, driven by gravity.

De façon bien connue, l'ouverture est ménagée dans la benne de sorte à s'étendre dans un plan sensiblement vertical. Dans ce cas, et lorsque l'ouverture est en partie inférieure de la benne, il peut être prévu que ledit bras du basculeur soit articulé au support par l'intermédiaire d'une simple liaison pivot, le moyen de préhension étant configuré de sorte à se retrouver positionné à proximité de l'axe de la liaison pivot, et afin d'éviter que le contenu du conteneur ne se déverse hors de la benne lors de sa course entre sa position en appui sur le sol à sa position de déversement dans la benne, sous l'effet notamment de la gravité. NL 7 807 475A enseigne un tel basculeur pour lequel l'axe de la liaison pivot est proche du moyen de préhension en particulier du peigne, le basculeur comprenant un support destiné à être fixé sur une partie d'un véhicule de collecte équipé d'une benne comprenant une ouverture supérieure s'étendant dans un plan sensiblement horizontal, ledit support étant prévu pour être fixé à proximité de ladite ouverture de la benne ; un bras comprenant deux extrémités longitudinales monté pivotant sur ledit support par l'intermédiaire d'une articulation pivotante d'axe au niveau d'une première extrémité longitudinale, ledit bras étant équipé d'un contre-peigne configuré pour venir appuyer contre la face supérieure de la lèvre de l'ouverture de déversement du conteneur ; un actionneur configuré pour entraîner le pivotement du bras par rapport au support autour dudit axe ; un peigne, monté mobile en coulissement par rapport au bras, selon une direction sensiblement longitudinale du bras, et configuré pour venir appuyer contre la face inférieure de ladite lèvre de l'ouverture de déversement du conteneur ; un actionneur configuré pour entraîner le coulissement du peigne par rapport au bras selon ladite direction sensiblement longitudinale du bras ; implicitement un moyen de commande relié auxdits actionneurs, dans lequel ledit peigne et ledit contre-peigne sont configurés pour venir enserrer ladite lèvre de l'ouverture de déversement du conteneur afin d'assurer le soulèvement et le maintien du conteneur sur le bras. Dans ce document de l'état de la technique lequel le moyen de commande est configuré de sorte à piloter lesdits actionneurs afin d'entraîner le coulissement du peigne par rapport au bras et le pivotement du bras par rapport au support afin de permettre le déversement du contenu du conteneur dans la benne au travers de ladite ouverture de la benne, avec les étapes : (a) coulissement du peigne par rapport au bras, jusqu'à ce que le contre-peigne se retrouve en appui contre la face supérieure de la lèvre de l'ouverture de déversement du conteneur et le peigne se retrouve en appui contre la face inférieure de la lèvre de l'ouverture de déversement du conteneur, dans une position initiale du bras pour laquelle le bras demeure orienté selon un angle sensiblement nul par rapport à la verticale ; (b) pivotement du bras par rapport au support depuis une sa position initiale et implicitement mise en oeuvre d'une accélération du bras par rapport au support, au moins à partir d'une position intermédiaire du bras, dans laquelle le bras définit un angle compris entre 70° et 90° par rapport à la verticale, jusqu'à une position de fin de course du bras, dans laquelle le bras définit un angle compris entre 120° et 160° par rapport à la verticale, de telle sorte que le contenu du conteneur est maintenu dans le conteneur entre la position intermédiaire et la position de fin de course du bras, par l'accélération du conteneur par rapport au support entre ladite position intermédiaire du bras et la position de fin de course du bras ; (c) freinage par moyen d'un cylindre hydraulique du bras par rapport au support, lorsque le bras se trouve dans ladite position de fin de course, de manière à provoquer l'éjection du contenu du conteneur dans la benne, au travers de l'ouverture de la benne.As is well known, the opening is made in the bucket so as to extend in a substantially vertical plane. In this case, and when the opening is in the lower part of the bucket, provision may be made for said rocker arm to be articulated to the support by means of a simple pivot connection, the gripping means being configured so as to be positioned close to the axis of the pivot link, and in order to prevent the contents of the container from spilling out of the bucket during its travel between its position resting on the ground in its dumping position in the bucket, under the effect in particular of gravity. NL 7 807 475A teaches such a tipper for which the axis of the pivot connection is close to the gripping means in particular of the comb, the tipper comprising a support intended to be fixed on a part of a collection vehicle equipped with a bucket comprising an opening upper extending in a substantially horizontal plane, said support being intended to be fixed close to said opening of the bucket; an arm comprising two longitudinal ends pivotally mounted on said support by means of a pivoting articulation with an axis at the level of a first longitudinal end, said arm being equipped with a counter-comb configured to come to bear against the upper face the lip of the container discharge opening; an actuator configured to cause the pivoting of the arm relative to the support around said axis; a comb, slidably mounted relative to the arm, in a substantially longitudinal direction of the arm, and configured to press against the underside of said lip of the container discharge opening; an actuator configured to cause the comb to slide relative to the arm in said substantially longitudinal direction of the arm; implicitly a control means connected to said actuators, in which said comb and said counter-comb are configured to grip said lip of the dumping opening of the container in order to ensure the lifting and the maintenance of the container on the arm. In this document of the state of the art in which the control means is configured so as to drive said actuators in order to cause the sliding of the comb relative to the arm and the pivoting of the arm relative to the support in order to allow the discharge of the content of the container in the bucket through said opening of the bucket, with the steps: (a) sliding of the comb relative to the arm, until the counter-comb is in contact with the upper face of the lip of the pouring opening of the container and the comb finds itself resting against the underside of the lip of the pouring opening of the container, in an initial position of the arm for which the arm remains oriented at a substantially zero angle with respect to vertically ; (b) pivoting of the arm relative to the support from its initial position and implicitly implementing an acceleration of the arm relative to the support, at least from an intermediate position of the arm, in which the arm defines an angle between 70° and 90° with respect to the vertical, up to a limit position of the arm, in which the arm defines an angle between 120° and 160° with respect to the vertical, such that the content of the container is held in the container between the intermediate position and the end of stroke position of the arm, by accelerating the container relative to the support between said intermediate position of the arm and the end of stroke position of the arm; (c) braking by means of a hydraulic cylinder of the arm relative to the support, when the arm is in said end-of-travel position, so as to cause the ejection of the contents of the container into the bucket, through the opening of the dumpster.

Le document DE 44 23 718 C1 divulgue des moyens d'entraînement d'un basculeur qui provoquent une accélération désirée à un conteneur de collecte de déchets.The document DE 44 23 718 C1 discloses a rocker drive means which causes a desired acceleration to a waste collection container.

Alternativement, l'ouverture peut être ménagée dans la benne, en partie supérieure de la benne, à une hauteur de l'ordre de 3 mètres par rapport au sol et de sorte à s'étendre dans un plan sensiblement horizontal, par exemple dans le cas où ledit véhicule de collecte est prévu pour réaliser une collecte sélective, nécessitant l'emploi d'une benne avec une pluralité de cheminées sensiblement verticales ménagées dans la benne, afin de faciliter le guidage des éléments dans la benne.Alternatively, the opening can be provided in the dumpster, in the upper part of the dumpster, at a height of the order of 3 meters relative to the ground and so as to extend in a substantially horizontal plane, for example in the case where said collection vehicle is intended to carry out selective collection, requiring the use of a dumpster with a plurality of substantially vertical chimneys formed in the dumpster, in order to facilitate the guiding of the elements in the dumpster.

Selon une telle alternative, ledit bras du basculeur est articulé au support par l'intermédiaire d'une liaison à la cinématique complexe, comprenant par exemple une pluralité de bielles articulées entre elles, afin de permettre le passage du conteneur de sa position en appui sur le sol à sa position de déversement de son contenu dans la benne, dans laquelle il va se trouver au-dessus de la benne, et en s'assurant que le contenu du conteneur ne se déverse pas hors de la benne lors de sa course entre ces deux positions, notamment sous l'effet de la gravité. Une telle cinématique est ainsi utilisée pour assurer le retournement du conteneur, seulement lorsque le conteneur arrive au droit d'une cheminée. Autrement dit, par cette cinématique complexe, distincte d'une simple rotation, on évite de déverser les produits contenus dans le conteneur en dehors de cette cheminée en retardant le retournement du conteneur, lors de la montée du conteneur par rapport à la benne.According to such an alternative, said rocker arm is articulated to the support by means of a complex kinematic connection, comprising for example a plurality of connecting rods articulated together, in order to allow the passage of the container from its position resting on the ground in its position for dumping its contents into the dumpster, in which it will be above the dumpster, and ensuring that the contents of the container do not spill out of the dumpster during its travel between these two positions, in particular under the effect of gravity. Such kinematics is thus used to ensure the reversal of the container, only when the container arrives in line with a stack. In other words, by this complex kinematics, distinct from a simple rotation, it is avoided to dump the products contained in the container outside this chimney by delaying the reversal of the container, during the rise of the container relative to the bucket.

Selon les constations de l'inventeur, la liaison à la cinématique complexe de l'articulation entre le bras du basculeur et le support peut nuire à la fiabilité du basculeur, notamment en raison des nombreuses bielles qui composent une telle liaison, et représente un coût de fabrication, de fonctionnement et d'entretien important.According to the observations of the inventor, the connection to the complex kinematics of the articulation between the arm of the rocker and the support can harm the reliability of the rocker, in particular because of the many connecting rods which make up such a connection, and represents a cost manufacturing, operation and major maintenance.

Egalement, que le basculeur soit destiné à déverser les produits du conteneur dans une ouverture s'étendant selon la verticale, en partie inférieure de la benne, sensiblement à hauteur d'homme ou une ouverture s'étendant selon un plan horizontal, en partie supérieure de la benne à une hauteur de l'ordre de 3 mètres, les basculeurs de l'état de la technique ne permettent pas toujours de vider des conteneurs dont les produits contenus forment un talus, ou sont tassés à l'intérieur du conteneur. Dans un tel cas, cela oblige de prévoir une fonction supplémentaire permettant l'exécution de brefs allers-retours du conteneur dans sa position de fin de course haute, typiquement par l'intermédiaire de plusieurs appuis sur un bouton de commande du basculeur par un opérateur.Also, whether the tipper is intended to dump the products from the container into an opening extending along the vertical, in the lower part of the dumpster, substantially at the height of a man, or an opening extending along a horizontal plane, in the upper part from the dumpster to a height of the order of 3 meters, the tilters of the state of the art do not always make it possible to empty containers whose contained products form an embankment, or are packed inside the container. In such a case, this makes it necessary to provide an additional function allowing the execution of brief round trips of the container in its upper limit position, typically via several presses on a rocker control button by an operator.

Selon les constatations des inventeurs, les produits non vidés lors de la première fin de course du basculeur constituent un problème à l'origine d'une perte de temps lors de la collecte.According to the observations of the inventors, the products not emptied during the first end of travel of the rocker constitute a problem at the origin of a loss of time during collection.

Problème techniqueTechnical problem

L'objectif de l'invention est donc de proposer un basculeur de conteneur pour véhicule de collecte, comprenant une benne avec une ouverture supérieure s'étendant dans un plan sensiblement horizontal, à la fiabilité améliorée et au coût de revient, de fonctionnement et d'entretien réduit.The object of the invention is therefore to provide a container tipper for a collection vehicle, comprising a dumpster with an upper opening extending in a substantially horizontal plane, with improved reliability and at a cost, operating and maintenance cost. reduced maintenance.

Un autre objectif de l'invention est de proposer un tel basculeur favorisant, voire garantissant, un déversement de l'intégralité du contenu du conteneur dans la benne, et sans nécessiter d'intervention d'un opérateur.Another object of the invention is to provide such a tipper which promotes, or even guarantees, a dumping of the entire contents of the container into the bucket, and without requiring the intervention of an operator.

Le procédé de l'invention inclut un basculeur 1 pour effectuer le déversement du contenu d'un conteneur 10 muni d'une lèvre 11 saillante avec une face supérieure FS 11 et une face inférieure FI12, entourant l'ouverture de déversement 12 du conteneur 10, comprenant :

The method of the invention includes a rocker 1 for discharging the contents of a container 10 provided with a projecting lip 11 with an upper face FS 11 and a lower face FI12, surrounding the discharge opening 12 of the container 10 , including:
  • a support 2 intended to be fixed to a part of a collection vehicle 100 equipped with a dumpster 101 comprising an upper opening 102 extending in a substantially horizontal plane, said support 2 being provided to be fixed close to said opening 102 of dumpster 101,
  • an arm 3, comprising two longitudinal ends 31, 32, pivotally mounted on said support 2 via a pivoting joint 4 of axis A at the level of a first longitudinal end 31, said arm 3 being equipped with a counter-comb 33, configured to come to rest against the upper face FS 11 of the lip 11 of the discharge opening 12 of the container 10, said counter-comb 33 being positioned in an intermediate position on said arm 3 between the first longitudinal end 31 and the second longitudinal end 32, at a distance D33 greater than 40 cm from the axis A, preferably between 50 cm and 80 cm, and at least one roller 34, configured to receive a side wall 13 of the container 10 in support , positioned at the level of the second longitudinal end 32 of the arm 3,
  • an actuator 5 configured to drive the pivoting of the arm 3 relative to the support 2 around said axis A,
  • a comb 6, mounted to slide relative to the arm 3, in a substantially longitudinal direction L3 of the arm 3, and configured to press against the lower face FI11 of the said lip 11 of the discharge opening 12 of the container 10,
  • an actuator 7 configured to cause the reed 6 to slide relative to the arm 3 in said substantially longitudinal direction L3 of the arm 3,
  • a control means connected to said actuators 5, 7.

Selon l'invention, ledit peigne 6 et ledit contre-peigne 33 sont configurés pour venir enserrer ladite lèvre 11 de l'ouverture de déversement 12 du conteneur 10 afin d'assurer le soulèvement et le maintien du conteneur 10 sur le bras 3.According to the invention, said comb 6 and said counter-comb 33 are configured to grip said lip 11 of the discharge opening 12 of the container 10 in order to ensure the lifting and the maintenance of the container 10 on the arm 3.

Selon l'invention, le moyen de commande est configuré de sorte à piloter lesdits actionneurs 5, 7 afin d'entraîner le coulissement du peigne 6 par rapport au bras 3 et le pivotement du bras 3 par rapport au support 2 afin de permettre le déversement du contenu du conteneur 10 dans la benne 101 au travers de ladite ouverture 102 de la benne 101, avec les étapes :

  1. (a) coulissement du peigne 6 par rapport au bras 3, jusqu'à ce que le contre-peigne 33 se retrouve en appui contre la face supérieure FS11 de la lèvre 11 de l'ouverture de déversement 12 du conteneur 10 et le peigne 6 se retrouve en appui contre la face inférieure FI11 de la lèvre de l'ouverture de déversement 12 du conteneur 10, dans une position initiale du bras 3 pour laquelle le bras 3 demeure orienté selon un angle sensiblement nul par rapport à la verticale V,
  2. (b) pivotement du bras 3 par rapport au support 2 depuis sa position initiale et mise en oeuvre d'une accélération du bras 3 par rapport au support 2, au moins à partir d'une position intermédiaire dans laquelle le bras 3 définit un angle compris entre 70° et 90° par rapport à la verticale V jusqu'à une position de fin de course du bras 3, dans laquelle le bras 3 définit un angle compris entre 120° et 160° par rapport à la verticale V, de telle sorte que le contenu du conteneur 10 est maintenu dans le conteneur 10 entre la position intermédiaire et la position de fin de course du bras 3 par l'accélération du conteneur 10 entre ladite position intermédiaire du bras 3 et la position de fin de course du bras 3,
  3. (c) freinage hydraulique du bras 3 par rapport au support 2, lorsque le bras 3 se trouve dans ladite position de fin de course, de manière à provoquer l'éjection du contenu du conteneur 10 dans la benne 101, au travers de l'ouverture de la benne 102.
According to the invention, the control means is configured so as to control said actuators 5, 7 in order to cause the sliding of the comb 6 relative to the arm 3 and the pivoting of the arm 3 relative to the support 2 in order to allow the dumping of the contents of the container 10 in the skip 101 through said opening 102 of the skip 101, with the steps:
  1. (a) sliding of the reed 6 relative to the arm 3, until the counter-reed 33 finds itself resting against the upper face FS11 of the lip 11 of the discharge opening 12 of the container 10 and the reed 6 finds itself resting against the lower face FI11 of the lip of the spill opening 12 of the container 10, in an initial position of the arm 3 for which the arm 3 remains oriented at a substantially zero angle with respect to the vertical V,
  2. (b) pivoting of the arm 3 relative to the support 2 from its initial position and implementation of an acceleration of the arm 3 relative to the support 2, at least from an intermediate position in which the arm 3 defines an angle between 70° and 90° with respect to the vertical V up to an end-of-travel position of the arm 3, in which the arm 3 defines an angle of between 120° and 160° with respect to the vertical V, such kind that the contents of the container 10 are maintained in the container 10 between the intermediate position and the end-of-travel position of the arm 3 by the acceleration of the container 10 between said intermediate position of the arm 3 and the end-of-travel position of the arm 3 ,
  3. (c) hydraulic braking of arm 3 relative to support 2, when arm 3 is in said end-of-travel position, so as to cause the contents of container 10 to be ejected into bucket 101, through the opening of the bucket 102.

Ainsi, grâce au basculeur 1 selon l'invention, comme visible plus particulièrement sur l'exemple de réalisation de la figure 5, le conteneur 10 peut être mis dans une position telle qu'il va se retrouver au-dessus de l'ouverture 102 de la benne 101 du camion de collecte 100, avec son ouverture de déversement 12 au-dessus de ladite ouverture 102 de la benne 101, pour que son contenu se déverse intégralement au travers de ladite ouverture 102 de la benne 101, avec le bras 3 articulé au support 2 par l'intermédiaire d'une simple liaison 4 d'axe A.Thus, thanks to the rocker 1 according to the invention, as can be seen more particularly in the embodiment of the figure 5 , the container 10 can be placed in a position such that it will find itself above the opening 102 of the dumpster 101 of the collection truck 100, with its dumping opening 12 above said opening 102 of the dumpster 101, so that its content flows entirely through said opening 102 of the dumpster 101, with the arm 3 articulated to the support 2 via a simple link 4 of axis A.

L'accélération linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 est telle lors du pivotement du bras 3 par rapport au support 2 entre sa position intermédiaire et sa position de fin de course, et donc l'accélération angulaire du conteneur 10 par rapport au support 2, que le contenu du conteneur 10 demeure à l'intérieur dudit conteneur 10, ladite accélération angulaire du bras 3 et donc du conteneur 10 par rapport au support 2 générant un effort s'opposant à la gravité, permettant de maintenir le contenu du conteneur 10 à l'intérieur de celui-ci, sans risquer de s'échapper, lorsque le conteneur 10 se trouve dans une phase critique, avec une position telle que l'ouverture de déversement 12 du conteneur 10 est orientée vers le bas, avant que le bras 3 n'atteigne ladite position de fin de course, dans laquelle l'ouverture de déversement 12 du conteneur 10 est au droit de l'ouverture 102 de la benne 101.The linear acceleration of the arm 3 with respect to the support 2 at the level of the counter-comb 33 is such during the pivoting of the arm 3 with respect to the support 2 between its intermediate position and its end-of-travel position, and therefore the angular acceleration of the container 10 relative to the support 2, that the contents of the container 10 remain inside said container 10, said angular acceleration of the arm 3 and therefore of the container 10 relative to the support 2 generating a force opposing gravity, making it possible to maintain the contents of the container 10 inside the latter, without the risk of escaping, when the container 10 is in a critical phase, with a position such that the discharge opening 12 of the container 10 is oriented downwards, before the arm 3 reaches said end-of-travel position, in which the discharge opening 12 of the container 10 is in line with the opening 102 of the bucket 101.

Egalement, le freinage hydraulique au cours de l'étape (c), permet de générer une décélération angulaire du bras 3, et donc du conteneur 10, par rapport au support 2 telle qu'un effort va s'appliquer sur le contenu du conteneur 10, l'entraînant vers l'extérieur de celui-ci, permettant d'entraîner l'intégralité de celui-ci en dehors du conteneur 10 de sorte à être déversé au travers de l'ouverture 102 de la benne 101.Also, the hydraulic braking during step (c), makes it possible to generate an angular deceleration of the arm 3, and therefore of the container 10, relative to the support 2 such that a force will be applied to the contents of the container. 10, driving it outwards from the latter, allowing the whole of it to be driven outside the container 10 so as to be dumped through the opening 102 of the bucket 101.

Ainsi avec une articulation 4 sous forme d'un simple pivot d'axe A, il est obtenu un basculeur 3 de conception particulièrement simple par rapport aux basculeurs de l'état de la technique, permettant d'assurer le déversement de l'intégralité du contenu d'un conteneur 10 au travers d'une ouverture supérieure 102 d'une benne 101 d'un véhicule de collecte 100, s'étendant dans un plan sensiblement horizontal, sans risquer de déverser une partie du contenu du conteneur 10 en dehors de ladite benne 101, lors du passage du conteneur de sa position initiale à sa position finale de déversement, et malgré un bras de levier important entre l'axe A de l'articulation 4 et le point de fixation du conteneur 10 au bras 3, correspondant sensiblement à la distance D33 entre l'axe A et le contre-peigne 33, permettant de faire passer le conteneur 10 au-dessus de ladite benne 101, celui-ci se trouvant habituellement positionné derrière le véhicule de collecte 100, avant que son contenu ne soit déversé dans ladite benne 101.Thus with an articulation 4 in the form of a simple pivot of axis A, a rocker 3 of particularly simple design is obtained compared to the rockers of the state of the technique, making it possible to ensure the dumping of the entire contents of a container 10 through an upper opening 102 of a bucket 101 of a collection vehicle 100, extending in a substantially horizontal plane , without the risk of dumping part of the contents of the container 10 outside of said skip 101, during the passage of the container from its initial position to its final dumping position, and despite a significant lever arm between the axis A of the articulation 4 and the point of attachment of the container 10 to the arm 3, corresponding substantially to the distance D33 between the axis A and the counter-comb 33, allowing the container 10 to pass above the said bucket 101, the latter usually positioned behind the collection vehicle 100, before its contents are dumped into said dumpster 101.

Le coût de revient, de fonctionnement et d'entretien est nettement réduit par rapport aux basculeurs de l'état de la technique.The cost, operating and maintenance cost is significantly reduced compared to state-of-the-art tilters.

Egalement, comme le freinage hydraulique intervenant au cours de l'étape (c) permet que l'intégralité du contenu du conteneur 10 soit éjecté de celui-ci et déversé au travers de l'ouverture supérieure 102 de la benne 101, et sans nécessiter de prévoir une fonction supplémentaire permettant l'exécution de brefs allers-retours du conteneur 10 dans la position de fin de course du bras 3.Also, as the hydraulic braking occurring during step (c) allows the entire contents of the container 10 to be ejected therefrom and dumped through the upper opening 102 of the bucket 101, and without requiring to provide an additional function allowing the execution of brief back and forth movements of the container 10 in the end-of-travel position of the arm 3.

Comme visible sur les exemples de réalisation des figures 2 à 5, l'actionneur 5 entraînant le pivotement du bras 3 par rapport au support 2 peut avantageusement être un vérin 5.As visible on the examples of realization of the figures 2 to 5 , the actuator 5 causing the pivoting of the arm 3 relative to the support 2 can advantageously be a cylinder 5.

Un deuxième actionneur 5, par exemple un deuxième vérin 5 peut être prévu afin de répartir l'effort exercé sur le bras 3 pour entraîner son pivotement par rapport au support entre deux actionneurs 2 et/ou pour améliorer la précision de son déplacement par rapport au support 2.A second actuator 5, for example a second jack 5 can be provided in order to distribute the force exerted on the arm 3 to drive its pivoting relative to the support between two actuators 2 and/or to improve the precision of its displacement relative to the support 2.

Comme visible également sur l'exemple de réalisation de la figure 1, l'actionneur 7 entraînant le coulissement du peigne 6 par rapport au bras 3 peut comprendre un moteur coopérant avec un système vis/écrou.As can also be seen in the embodiment of the figure 1 , the actuator 7 causing the sliding of the reed 6 with respect to the arm 3 can comprise a motor cooperating with a screw/nut system.

Un deuxième actionneur 7, par exemple un deuxième moteur coopérant avec un deuxième système vis/écrou peut être prévu afin de répartir l'effort exercé sur le peigne 6 pour entraîner son coulissement par rapport au bras 3 entre deux actionneurs et/ou pour améliorer la précision de son déplacement par rapport bras 3.A second actuator 7, for example a second motor cooperating with a second screw/nut system can be provided in order to distribute the force exerted on the comb 6 to cause it to slide relative to arm 3 between two actuators and/or to improve the precision of its movement relative to arm 3.

Le moyen de commande peut par exemple comprendre un distributeur hydraulique, piloté électroniquement, et/ou une électronique de commande.The control means may for example comprise a hydraulic distributor, electronically controlled, and/or control electronics.

Selon un mode de réalisation, ladite distance D33 entre l'axe A de l'articulation 4 et le contre-peigne 33 du bras 3 est comprise entre 50 cm et 80 cm.According to one embodiment, said distance D33 between the axis A of the joint 4 and the counter-comb 33 of the arm 3 is between 50 cm and 80 cm.

Cela permet, en plus de permettre le passage du conteneur 10 au-dessus de la benne 101, d'éviter que le conteneur 10 ne se retrouve trop haut par rapport à la benne 101, lorsque le bras 3 se trouve dans sa position de fin de course, ce qui pourrai nuire à la stabilité du véhicule de collecte 100.This makes it possible, in addition to allowing the passage of the container 10 above the bucket 101, to prevent the container 10 from being too high relative to the bucket 101, when the arm 3 is in its end position. racing, which could affect the stability of the collection vehicle 100.

Selon le procédé de l'invention, le moyen de commande et/ou ledit actionneur 5 entraînant le pivotement du bras 3 par rapport au support 2 sont configurés de sorte qu'au cours de l'étape (b) entre ladite position intermédiaire et la position de fin de course du bras 3 :

  • l'accélération linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 est comprise entre 1,5 m.s-2 et 5 m.s-2, et
  • la vitesse linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 est comprise entre 1 m.s-1 et 3 m.s-1.
According to the method of the invention, the control means and/or said actuator 5 driving the pivoting of arm 3 relative to support 2 are configured so that during step (b) between said intermediate position and the limit position of arm 3:
  • the linear acceleration of the arm 3 with respect to the support 2 at the level of the counter-comb 33 is between 1.5 ms -2 and 5 ms -2 , and
  • the linear speed of the arm 3 with respect to the support 2 at the level of the counter-comb 33 is between 1 ms -1 and 3 ms -1 .

Comme expliqué précédemment, une telle accélération linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 permet de s'assurer que l'accélération angulaire du bras 3, et donc du conteneur 10, par rapport au support 2 soit telle que celle-ci génère un effort sur le contenu du conteneur 10 lors de son passage de la position initiale à la position de fin de course, le maintenant à l'intérieur dudit conteneur 10.As explained previously, such a linear acceleration of the arm 3 relative to the support 2 at the level of the counter-comb 33 makes it possible to ensure that the angular acceleration of the arm 3, and therefore of the container 10, relative to the support 2 is such that this generates a force on the contents of the container 10 during its passage from the initial position to the end position, keeping it inside said container 10.

Sur le graphique représenté à la figure 6b, ladite étape (b) intervient entre 1,4 et 2s, et comme visible sur ladite figure 6b, l'accélération linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 peut être croissante, de façon sensiblement exponentielle, de sorte à augmenter de façon également sensiblement exponentielle l'effort maintenant le contenu du conteneur 10 à l'intérieur de celui-ci au cours de l'étape (b), et notamment plus l'angle par rapport à la verticale du bras 3 augmente, et donc plus le contenu du conteneur 10 risque de sortir par l'ouverture de déversement 12 du conteneur 10, entraîné par la gravité.On the graph shown in figure 6b , said step (b) occurs between 1.4 and 2s, and as visible on said figure 6b , the linear acceleration of the arm 3 with respect to the support 2 at the level of the counter-comb 33 can be increasing, in a substantially exponential manner, so as to also increase in a substantially exponential manner the force maintaining the contents of the container 10 at the interior thereof during step (b), and in particular the more the angle relative to the vertical of the arm 3 increases, and therefore the more the contents of the container 10 may exit through the spill opening 12 of the container 10, driven by gravity.

La vitesse linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 comprise entre 1 m.s-1 et 3 m.s-1, permet de minimiser la durée de ladite étape (b), pouvant avantageusement être comprise entre 0,4 secondes et 0,8 secondes, de préférence sensiblement égale à 0,6 secondes, comme visible sur l'exemple de réalisation de la figure 6b, et de parvenir à ladite accélération linéaire comprise entre 1,5 m.s-2 et 5 m.s-2.The linear speed of the arm 3 relative to the support 2 at the level of the counter-comb 33 of between 1 ms -1 and 3 ms -1 , makes it possible to minimize the duration of said step (b), which can advantageously be between 0.4 seconds and 0.8 seconds, preferably substantially equal to 0.6 seconds, as visible in the embodiment of the figure 6b , and to achieve said linear acceleration of between 1.5 ms -2 and 5 ms -2 .

Comme visible sur l'exemple de réalisation de la figure 6a, ladite vitesse linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 peut également croître de façon sensiblement exponentielle au cours de ladite étape (b).As visible on the embodiment of the figure 6a , said linear speed of arm 3 relative to support 2 at counter-comb 33 can also increase substantially exponentially during said step (b).

Selon un mode de réalisation, le moyen de commande et/ou ledit actionneur 5 entraînant le pivotement du bras 3 par rapport au support 2 sont configurés de sorte qu'au cours de l'étape (b), entre la position initiale et la position intermédiaire du bras 3, le bras 3 est pivoté par rapport au support 2, avec :

  • l'accélération linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 inférieure à 0,5 m.s-2, et
  • la vitesse linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 inférieure à 1,5 m.s-1.
According to one embodiment, the control means and/or said actuator 5 driving the pivoting of the arm 3 with respect to the support 2 are configured so that during step (b), between the initial position and the position intermediate arm 3, arm 3 is pivoted relative to support 2, with:
  • the linear acceleration of the arm 3 with respect to the support 2 at the level of the counter-comb 33 of less than 0.5 ms -2 , and
  • the linear speed of the arm 3 with respect to the support 2 at the level of the counter-comb 33 less than 1.5 ms -1 .

Comme représenté sur les exemples de réalisation des figures 6a et 6b, ces accélérations linéaires et ces vitesses linéaires sont bien inférieures à celles mises en oeuvre au cours de l'étape (b), lors du pivotement du bras 3 par rapport au support 2 entre sa position intermédiaire et sa position de fin de course, car il n'y a pas de nécessité d'avoir une accélération angulaire au du bras 3, et donc du conteneur 10, par rapport au support 2 telle que le contenu du conteneur 10 demeure à l'intérieur de celui-ci, la position de l'ouverture de déversement 12 du conteneur 10 empêchant que celui-ci soit entraîné vers l'extérieur du conteneur à cause de la gravité, comme visible sur les exemples de réalisation des figures 3 et 4.As shown in the example embodiments of the figures 6a and 6b , these linear accelerations and these linear velocities are much lower than those implemented during step (b), during the pivoting of the arm 3 with respect to the support 2 between its intermediate position and its end-of-travel position, because there is no need to have an angular acceleration of the arm 3, and therefore of the container 10, relative to the support 2 such that the contents of the container 10 remain inside the latter, the position of the overflow opening 12 of the container 10 preventing the latter from being drawn out of the container because of gravity, as can be seen in the examples of embodiments of the figure 3 And 4 .

Comme visible sur les exemples de réalisation des figures 6a et 6b, le pivotement du bras 3 entre sa position initiale et sa position intermédiaire intervenant entre 0 et 1,4 secondes, ladite accélération linéaire et ladite vitesse linéaire peuvent être sensiblement constantes ou varier faiblement au cours de celui-ci.As visible on the examples of realization of the figures 6a and 6b , the pivoting of the arm 3 between its initial position and its intermediate position occurring between 0 and 1.4 seconds, said linear acceleration and said linear speed can be substantially constant or vary slightly during this.

Selon un mode de réalisation, le moyen de commande et/ou ledit actionneur 5 entraînant le pivotement du bras 3 par rapport au support 2 sont configurés de sorte que la durée du pivotement du bras 3 entre sa position initiale et sa position intermédiaire, au cours de l'étape (b), est comprise entre 1s et 1,5s.According to one embodiment, the control means and/or said actuator 5 driving the pivoting of the arm 3 relative to the support 2 are configured so that the duration of the pivoting of the arm 3 between its initial position and its intermediate position, during of step (b), is between 1s and 1.5s.

Ceci est dû au fait que l'accélération linéaire et la vitesse linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33 sont réduites par rapport à celles lors du pivotement du bras (3) par rapport au support (2) entre sa position intermédiaire et sa position de fin course, ce qui permet de réduire la consommation énergétique dudit actionneur 5 au cours de l'étape (a').This is due to the fact that the linear acceleration and the linear speed of the arm 3 relative to the support 2 at the level of the counter-comb 33 are reduced compared to those during the pivoting of the arm (3) relative to the support (2) between its intermediate position and its end-of-travel position, which makes it possible to reduce the energy consumption of said actuator 5 during step (a′).

Selon un mode de réalisation, le moyen de commande et/ou ledit actionneur 5 entraînant le pivotement du bras 3 par rapport au support 2 sont configurés de sorte que la vitesse linéaire du bras 3 par rapport au support 2 au niveau du contre-peigne 33, à la fin de l'étape (b), est comprise entre 2 m.s-1 et 3 m.s-1.According to one embodiment, the control means and/or said actuator 5 driving the pivoting of the arm 3 relative to the support 2 are configured so that the linear speed of the arm 3 relative to the support 2 at the level of the counter-comb 33 , at the end of step (b), is between 2 m.s-1 and 3 m.s-1.

Grâce à cette disposition avantageuse de l'invention, la vitesse angulaire du bras 3, et donc du conteneur 10, par rapport au support 2 est élevée au début de l'étape (c), et le freinage hydraulique intervenant au cours de l'étape (c) engendre une décélération angulaire brusque et importante du bras 3, et donc du conteneur 10, par rapport au support 2, permettant la génération dudit effort permettant l'éjection du contenu du conteneur 10 hors de celui-ci, au travers de l'ouverture supérieur 102 de la benne 101 du véhicule de collecte 100.Thanks to this advantageous arrangement of the invention, the angular speed of the arm 3, and therefore of the container 10, relative to the support 2 is high at the start of step (c), and the hydraulic braking occurring during the step (c) generates a sudden and significant angular deceleration of the arm 3, and therefore of the container 10, relative to the support 2, allowing the generation of said force allowing the ejection of the contents of the container 10 out of the latter, through the upper opening 102 of the bucket 101 of the collection vehicle 100.

Selon un mode de réalisation, ledit actionneur 5 entraînant le pivotement du bras 3 par rapport au support 2 comprend un vérin 5 avec un corps 51 recevant en coulissement un piston 52, le corps du vérin 51 comprenant un étranglement, configuré pour assurer le freinage du piston 52 par rapport au corps 51 afin de réaliser le freinage hydraulique de l'étape (c).According to one embodiment, said actuator 5 causing the pivoting of the arm 3 with respect to the support 2 comprises a cylinder 5 with a body 51 slidably receiving a piston 52, the body of the cylinder 51 comprising a throttle, configured to ensure the braking of the piston 52 with respect to body 51 in order to perform the hydraulic braking of step (c).

L'étranglement (non représenté) est positionné dans le corps 51 du vérin 5 à une position correspondant à ladite position du piston 52 par rapport au corps 51 matérialisant la fin de course du pivotement du bras 3 par rapport au support 2 à l'issue de l'étape (b).The throttle (not shown) is positioned in the body 51 of the cylinder 5 at a position corresponding to said position of the piston 52 relative to the body 51 materializing the end of the pivoting stroke of the arm 3 relative to the support 2 at the end of step (b).

Un tel étranglement permet d'assurer mécaniquement, de façon simple, le freinage hydraulique de l'étape (c) en garantissant la décélération souhaitée du bras 3, et donc du conteneur 10, par rapport au support 2, assurant l'éjection du contenu du conteneur 10 au travers de l'ouverture de déversement 12 dudit conteneur 10.Such a throttle makes it possible to ensure mechanically, in a simple way, the hydraulic braking of step (c) by guaranteeing the desired deceleration of the arm 3, and therefore of the container 10, relative to the support 2, ensuring the ejection of the contents of the container 10 through the discharge opening 12 of said container 10.

Selon un mode de réalisation, le moyen de commande et/ou ledit actionneur 7 entraînant le coulissement du peigne 6 par rapport au bras 3 sont configurés de sorte que la course de coulissement C6 du peigne 6 par rapport au bras 3 au cours de l'étape (a) est comprise entre 30cm et 1m, par exemple 50 cm.According to one embodiment, the control means and/or said actuator 7 causing the reed 6 to slide relative to the arm 3 are configured so that the sliding stroke C6 of the reed 6 relative to the arm 3 during the step (a) is between 30cm and 1m, for example 50 cm.

Comme visible par exemple sur l'exemple de réalisation de la figure 3, une telle course de coulissement C6 du peigne 6 par rapport au bras 3, combinée à la distance D33 séparant l'axe A de l'articulation 4 du contre-peigne 33, supérieure à 50 cm permet de s'assurer que le conteneur 10 puisse passer d'une position en appui sur le sol à proximité du véhicule de collecte 100, dans la configuration initiale représentée par exemple sur l'exemple de réalisation de la figure 2, à une position de déversement de son contenu au travers de l'ouverture 102 de la benne 101 du véhicule de collecte 100, dans la configuration finale, représentée par exemple sur l'exemple de réalisation de la figure 5, en prévoyant un basculeur 1 de conception particulièrement simple, prévoyant un bras 3 articulé au support 2 par une simple articulation 4 d'axe A.As visible for example on the embodiment of the picture 3 , such a sliding stroke C6 of the reed 6 relative to the arm 3, combined with the distance D33 separating the axis A from the articulation 4 of the counter-reed 33, greater than 50 cm makes it possible to ensure that the container 10 can pass from a position resting on the ground close to the collection vehicle 100, in the initial configuration represented for example on the embodiment of the figure 2 , in a position for dumping its contents through the opening 102 of the bucket 101 of the collection vehicle 100, in the final configuration, represented for example on the exemplary embodiment of the figure 5 , by providing a rocker 1 of particularly simple design, providing an arm 3 articulated to the support 2 by a simple articulation 4 of axis A.

L'invention concerne également un procédé mis en oeuvre par un véhicule de collecte 100 comprenant :

  • une benne 101 munie d'une ouverture supérieure 102 s'étendant dans un plan sensiblement horizontal,
  • un basculeur 1 selon l'un des modes de réalisation décrits précédemment, dont le support 2 est fixé sur une partie du véhicule 100 à proximité de ladite ouverture supérieure 102 de la benne 101.
The invention also relates to a method implemented by a collection vehicle 100 comprising:
  • a bucket 101 provided with an upper opening 102 extending in a substantially horizontal plane,
  • a rocker 1 according to one of the embodiments described previously, the support 2 of which is fixed to a part of the vehicle 100 close to said upper opening 102 of the bucket 101.

Le support 2 du basculeur 1 peut par exemple être fixé sur le châssis du véhicule de collecte 100, afin de garantir la stabilité dudit support 2.The support 2 of the tilter 1 can for example be fixed on the frame of the collection vehicle 100, in order to guarantee the stability of said support 2.

Un tel véhicule de collecte 100 peut par exemple être un véhicule poids lourd employé pour la collecte des déchets, destiné à recevoir des déchets stockés dans des conteneurs 10.Such a collection vehicle 100 can for example be a heavy vehicle used for waste collection, intended to receive waste stored in containers 10.

Les avantages décrits précédemment concernant ledit basculeur 1 selon l'invention s'appliquent également au véhicule de collecte 100 équipé d'un tel basculeur 1.The advantages described above concerning said tilter 1 according to the invention also apply to the collection vehicle 100 equipped with such a tilter 1.

Naturellement, d'autres modes de réalisation auraient pu être envisagés par l'homme du métier sans pour autant sortir du cadre de l'invention définie par les revendications ci-après.Naturally, other embodiments could have been envisaged by those skilled in the art without thereby departing from the scope of the invention defined by the claims below.
