Description

La présente invention se situe dans le domaine de la collecte des ordures, et elle a plus particulièrement trait à un système de collecte de conteneurs de bio-déchets. Le traitement des bio-déchets présente des enjeux spécifiques en ce qu'ils sont composés de matières organiques, par conséquent biodégradables par des micro-organismes, et dès lors susceptibles de changer rapidement d'état, pouvant notamment devenir liquides ou semi-liquides, et/ou présenter des résidus fermentés.The present invention is in the field of garbage collection, and it relates more particularly to a system for collecting containers of bio-waste. The treatment of bio-waste presents specific challenges in that it is composed of organic matter, therefore biodegradable by micro-organisms, and therefore likely to change state rapidly, in particular being able to become liquid or semi-liquid, and/or present fermented residues.

La gestion de ce type de déchet doit être prévue et conçue en conséquence, et il est notamment indispensable de nettoyer les conteneurs après les avoir correctement vidés. Leur structure peut en effet être endommagée avec le temps s'ils ne sont pas lavés régulièrement. Les effets des bio-déchets sur les surfaces avec lesquelles ils entrent en contact, dont celles des conteneurs de stockage, deviennent aussi potentiellement vecteurs de problèmes sanitaires.The management of this type of waste must be planned and designed accordingly, and it is particularly essential to clean the containers after having emptied them correctly. Their structure can indeed be damaged over time if they are not washed regularly. The effects of bio-waste on the surfaces with which they come into contact, including those of storage containers, also become potential vectors of health problems.

En pratique, les questions liées aux traitements des bio-déchets et des conteneurs de bio-déchets sont indissociables, les conséquences de l'une ayant des répercussions directes et immédiates sur l'autre et vice-versa. La gestion de l'organisation de la collecte de bio-déchets doit impérativement prendre en considération les questions sanitaires évoquées auparavant, et prendre appui sur des réponses techniques assurant tout d'abord que les conteneurs soient vidangés puis nettoyés dans les meilleures conditions.In practice, issues related to the treatment of bio-waste and bio-waste containers are inseparable, the consequences of one having direct and immediate repercussions on the other and vice versa. The management of the organization of the collection of bio-waste must imperatively take into consideration the health issues mentioned above, and rely on technical responses ensuring first of all that the containers are emptied and then cleaned in the best conditions.

Ainsi, selon un système de collecte de bio-déchets déjà développé par le présent déposant, celui-ci comporte un véhicule de type camion comprenant un châssis équipé d'une cuve de stockage des bio-déchets, d'une trémie de réception de ces déchets, de moyens mécaniques de collecte de conteneurs de bio-déchets présentant au moins un bras de préhension et aptes à déplacer chaque conteneur entre un emplacement au sol et au moins une position de vidange sur le véhicule, et un module de lavage comportant des moyens de lavage du conteneur. Le nettoyage s'effectue évidemment après vidange du conteneur, lors du trajet entre deux emplacements successifs de collecte de conteneurs. Lors de l'arrivée à chaque nouvel emplacement, le conteneur plein est embarqué, et remplacé par un conteneur vide et propre. La plupart du temps, le camion ne contient qu'un seul conteneur, mais au moment de la collecte et de l'échange, il en contient deux.Thus, according to a bio-waste collection system already developed by the present applicant, it comprises a truck-type vehicle comprising a chassis equipped with a bio-waste storage tank, a hopper for receiving these waste, mechanical means for collecting bio-waste containers having at least one gripping arm and capable of moving each container between a location on the ground and at least one emptying position on the vehicle, and a washing module comprising means container washing. The cleaning obviously takes place after the container has been emptied, during the journey between two successive container collection locations. Upon arrival at each new location, the full container is loaded, and replaced by an empty and clean container. Most of the time, the truck only contains one container, but at the time of collection and exchange, it contains two.

Pour que les opérations de collecte et de vidange du conteneur collecté et de dépose du conteneur nettoyé soient techniquement optimisées, et que les opérations intermédiaires de vidange et de nettoyage puissent par exemple se dérouler sans interactions indésirables, la conception des moyens techniques réalisant les différentes fonctions, puis leur fonctionnement combiné, doit être tout particulièrement étudiée.So that the collection and emptying operations of the collected container and the removal of the cleaned container are technically optimized, and that the intermediate emptying and cleaning operations can for example take place without undesirable interactions, the design of the technical means carrying out the different functions , then their combined operation, must be particularly studied.

Ces moyens techniques doivent également être étudiés pour être compacts. Ils doivent permettre le déplacement d'un ou deux bacs d'un volume d'environ 200 litres dans le gabarit du camion afin d'en permettre la vidange et le nettoyage sur toutes les faces du bac.These technical means must also be designed to be compact. They must allow the movement of one or two bins with a volume of approximately 200 liters in the lorry's size to allow emptying and cleaning on all sides of the tank.

Ce sont les objectifs de la présente invention, qui s'attache plus particulièrement aux moyens techniques liés à la collecte des conteneurs, puis secondairement à leur vidange dans le véhicule. De manière structurellement classique et déjà connue, le système de collecte de l'invention comporte très généralement un véhicule de type camion comprenant, à l'arrière d'une cabine de pilotage, un châssis surmonté d'une caisse équipée d'une cuve de stockage des bio-déchets, d'une trémie de réception de ces déchets, d'un module de lavage comportant des moyens de lavage de conteneurs, de moyens mécaniques de collecte de conteneurs de bio-déchets présentant un bras de chargement au niveau d'une façade latérale du véhicule. Ces moyens de collecte sont aptes à déplacer chaque conteneur entre un emplacement au sol et une position de vidange sur le véhicule, ledit conteneur comportant dès lors des moyens de fixation au bras de chargement.These are the objectives of the present invention, which relates more particularly to the technical means linked to the collection of the containers, then secondarily to their emptying in the vehicle. In a conventional and already known structural manner, the collection system of the invention very generally comprises a vehicle of the truck type comprising, at the rear of a cockpit, a frame surmounted by a box equipped with a tank of storage of bio-waste, of a hopper for receiving this waste, of a washing module comprising means for washing containers, of mechanical means for collecting containers of bio-waste having a loading arm at the level of a side wall of the vehicle. These collection means are capable of moving each container between a location on the ground and an emptying position on the vehicle, said container therefore comprising means for attachment to the loading arm.

Plus particulièrement, il est prévu que :

  • le bras de chargement comporte un support de liaison au châssis et un rail muni de moyens de guidage et d'entraînement d'un chariot supportant une platine de chargement/déchargement de conteneurs munie de moyens d'accrochage et de verrouillage/déverrouillage d'un conteneur consistant en au moins un crochet de levage à ouverture supérieure ; et
  • ledit rail présentant un premier tronçon se développant sensiblement verticalement, et un second tronçon supérieur se recourbant vers l'intérieur du véhicule et situé à un niveau supérieur à celui d'une ouverture de la trémie.
More specifically, it is expected that:
  • the loading arm comprises a support for connecting to the chassis and a rail provided with means for guiding and driving a carriage supporting a container loading/unloading plate provided with means for hooking and locking/unlocking a container consisting of at least one top-opening lifting hook; and
  • said rail having a first section developing substantially vertically, and a second upper section curving towards the interior of the vehicle and located at a level above that of an opening of the hopper.

Le dispositif de collecte des conteneurs est par conséquent basé sur un bras relié au véhicule, doté de moyens mobiles d'accrocher puis de solidariser un conteneur, lequel est déplacé sensiblement verticalement le long du bras via un rail de guidage jusqu'à être basculé en position de vidange au-dessus de la trémie de réception des déchets avant d'être lavé. Le fonctionnement est réversible, permettant de reposer un conteneur au sol une fois vidé et nettoyé.The container collection device is therefore based on an arm connected to the vehicle, provided with movable means for hooking then securing a container, which is moved substantially vertically along the arm via a guide rail until it is tilted emptying position above the waste reception hopper before being washed. Operation is reversible, allowing a container to rest on the ground once emptied and cleaned.

Ce type de mécanisme est déjà connu, par exemple montré dans les documents KR 2006 0126071 ou CN 110 641 883 , qui portent cependant sur d'autres parties des véhicules de collecte et ne décrivent pas comment s'effectuent l'accroche et la dépose des conteneurs à déchets. Or, il s'agit d'une question technique évidemment indispensable à résoudre, de préférence de manière simple et fiable, faute de quoi le reste des fonctionnalités offertes par le véhicule de collecte ne peut être mises en œuvre. C'est ce que propose le système de la présente invention.This type of mechanism is already known, for example shown in the documents KR 2006 0126071 Where CN 110 641 883 , which however relate to other parts of the collection vehicles and do not describe how the attachment and removal of the waste containers is carried out. However, this is an obviously essential technical question to be resolved, preferably in a simple and reliable manner, failing which the rest of the functionalities offered by the collection vehicle cannot be implemented. This is what the system of the present invention provides.

A cet effet, dans le système de collecte de l'invention, la platine est munie de deux crochets de levage à ouverture supérieure, les ouvertures des crochets étant alignées horizontalement pour le chargement des conteneurs, chaque conteneur comportant une barre extérieure horizontale de levage par les crochets.To this end, in the collection system of the invention, the plate is provided with two lifting hooks with an upper opening, the openings of the hooks being aligned horizontally for the loading of the containers, each container comprising a horizontal outer bar for lifting by the hooks.

Il s'agit d'une solution mécaniquement simple et robuste, qui est au surplus de mise en œuvre particulièrement efficace en combinaison avec le reste de l'invention, c'est-à-dire principalement le chariot supportant la platine de chargement/déchargement. Le déplacement de ce dernier est guidé par le rail de manière à pouvoir accrocher ou décrocher les conteneurs sans opérations mécaniques complexes, mais de manière très naturelle en utilisant notamment le poids des conteneurs pour assurer une liaison stable avec le chariot.This is a mechanically simple and robust solution, which is moreover particularly effective implementation in combination with the rest of the invention, that is to say mainly the carriage supporting the loading / unloading plate. The movement of the latter is guided by the rail so as to be able to hook or unhook the containers without complex mechanical operations, but in a very natural way by using in particular the weight of the containers to ensure a stable connection with the trolley.

A des fins d'optimisation du guidage, le rail comporte d'ailleurs de préférence deux glissières latérales guidant chacune au moins un galet du chariot. Ce dernier, ainsi guidé par les glissières latérales, peut progresser le long du rail dans un sens ou dans l'autre.For guidance optimization purposes, the rail also preferably comprises two lateral slideways each guiding at least one roller of the carriage. The latter, thus guided by the side rails, can progress along the rail in one direction or the other.

Le système est conçu pour que l'accrochage du conteneur au chariot mobile puisse se faire dans les meilleures conditions : les glissières latérales, dans le premier tronçon du rail, présentent une courbure guidant le chariot depuis une butée inférieure jusqu'au second tronçon supérieur, respectivement entre d'une part une position de la platine inclinée avec le ou les crochets basculés vers l'extérieur, au moins jusqu'à ce que le ou les crochets soi(en)t au niveau de la barre d'accrochage d'un conteneur posé au sol, et d'autre part une inclinaison inversée vers la caisse du véhicule au voisinage du second tronçon supérieur.The system is designed so that the hooking of the container to the mobile trolley can be done in the best conditions: the side slides, in the first section of the rail, have a curvature guiding the trolley from a lower stop to the second upper section, respectively between, on the one hand, a position of the plate inclined with the hook or hooks tilted outwards, at least until the hook or hooks are at the level of the attachment bar of a container placed on the ground, and on the other hand an inverted inclination towards the body of the vehicle in the vicinity of the second upper section.

Le chariot et la platine changent donc progressivement d'orientation à mesure qu'ils parcourent le rail, guidés par les glissières, de manière à pouvoir glisser le ou les crochets sous la barre du conteneur en remontant ou à les séparer en descendant. Lorsque le chariot est entraîné vers le haut, le ou les crochets rencontre(nt) la barre qui est disposée sur leur chemin, tel un obstacle, et commencent à soulever le conteneur car, après contact, ladite barre se trouve en appui sur le ou les crochets, y reposant par gravité. Dans la partie supérieure du premier tronçon d'allure verticale du rail, l'orientation du chariot, de la platine et par conséquent du conteneur change, amorçant la bascule qui aura lieu au sommet, au niveau du second tronçon supérieur.The carriage and the plate therefore gradually change orientation as they run along the rail, guided by the slideways, so as to be able to slide the hook or hooks under the bar of the container when going up or to separate them when going down. When the carriage is driven upwards, the hook(s) encounter(s) the bar which is placed in their path, like an obstacle, and begin to lift the container because, after contact, said bar is resting on the bar(s). the hooks, resting there by gravity. In the upper part of the first vertical section of the rail, the orientation of the carriage, of the plate and consequently of the container changes, initiating the rocking which will take place at the top, at the level of the second upper section.

Selon une possibilité, le ou les crochets de levage est/sont placé(s) au-dessus d'au moins deux ergots escamotables de la platine, mobiles entre une position de verrouillage et une position de déverrouillage, chaque conteneur comportant des orifices de verrouillage logeant l'extrémité libre des ergots escamotables lorsqu'ils sont en position de verrouillage. Ainsi, après l'accrochage du conteneur par le ou les crochets de la platine, un verrouillage de l'une à l'autre est effectué.According to one possibility, the lifting hook(s) is/are placed above at least two retractable lugs of the plate, movable between a locking position and an unlocking position, each container comprising locking holes housing the free end of the retractable lugs when they are in the locking position. Thus, after the hooking of the container by the hook or hooks of the plate, locking from one to the other is performed.

En fait, de préférence selon la solution de l'invention, les ergots de la platine se positionnent dans l'alignement des orifices de verrouillage du conteneur lorsque la platine est verticale. Le verrouillage intervient donc un peu après l'accrochage du conteneur qui s'effectue lorsque la platine est encore inclinée, à un moment ultérieur dans la remontée du chariot où la platine est verticale. L'accrochage et le verrouillage sont donc séquentiels.In fact, preferably according to the solution of the invention, the lugs of the plate are positioned in alignment with the locking holes of the container when the plate is vertical. The locking therefore occurs shortly after the hooking of the container which takes place when the plate is still tilted, at a later moment in the ascent of the carriage where the plate is vertical. Hooking and locking are therefore sequential.

Plus précisément encore, les deux ergots escamotables sont entraînés simultanément en translation en sens opposé par un dispositif d'escamotage les entraînant entre la position de verrouillage et la position de déverrouillage. Ils agissent donc en même temps, verrouillant le conteneur en une même phase, via des déplacements opposés.More precisely still, the two retractable lugs are driven simultaneously in translation in opposite directions by a retracting device the driving between the locking position and the unlocking position. They therefore act at the same time, locking the container in the same phase, via opposite movements.

Selon une configuration possible, le dispositif d'escamotage peut comporter un vérin fixé à la platine et dont l'extrémité libre de la tige comporte une liaison à rotation avec les premières extrémités de deux biellettes dont les secondes extrémités sont reliées à rotation chacune avec un ergot, ledit ergot étant coulissable dans des moyens de guidage en translation solidarisés à la platine.According to one possible configuration, the retraction device may comprise a cylinder fixed to the plate and the free end of the rod of which comprises a rotational connection with the first ends of two connecting rods, the second ends of which are each connected in rotation with a lug, said lug being slidable in translation guide means secured to the plate.

Lorsque le vérin est commandé, il actionne en translation les ergots entre une position rétractée sans contact mécanique avec le conteneur et une position déployée de verrouillage à l'intérieur des orifices pratiqués dans les conteneurs. Pour réaliser le verrouillage, le vérin est par conséquent piloté pour déployer les ergots, ce qui implique que lesdits orifices soient dans l'axe de leur déplacement. L'alignement peut comme on l'a vu résulter notamment du positionnement du chariot et de la platine qui porte les ergots par rapport au rail, au cours du trajet de guidage : dès que la platine devient verticale au cours de son déplacement, il y a alignement. Dans ce cas, au cours de la montée, le vérin est actionné pour déployer les ergots en vue d'un verrouillage. A la descente, il est au contraire commandé pour rétracter les ergots, déverrouillant le conteneur qui reste néanmoins accroché puisqu'il repose par gravité sur le ou les crochets. Celui-ci ou ceux-ci se sépare(nt) naturellement de la barre lorsque le fond du conteneur touche terre. A ce moment, la platine portant le ou les crochets étant inclinée, il n'y a pas d'obstacle à la séparation.When the cylinder is controlled, it actuates the lugs in translation between a retracted position without mechanical contact with the container and a deployed locking position inside the orifices made in the containers. To achieve the locking, the cylinder is therefore controlled to deploy the lugs, which implies that said orifices are in the axis of their movement. The alignment can, as we have seen, result in particular from the positioning of the carriage and the plate which carries the lugs with respect to the rail, during the guide path: as soon as the plate becomes vertical during its movement, there has alignment. In this case, during the ascent, the actuator is actuated to deploy the lugs for locking. When descending, it is on the contrary controlled to retract the lugs, unlocking the container which nevertheless remains attached since it rests by gravity on the hook or hooks. This or these separate(s) naturally from the bar when the bottom of the container hits the ground. At this time, the plate carrying the hook or hooks being inclined, there is no obstacle to the separation.

De préférence, les ergots sont disposés selon un axe horizontal parallèle à la barre d'accrochage.Preferably, the lugs are arranged along a horizontal axis parallel to the attachment bar.

Les moyens d'accrochage et de verrouillage sont par conséquent distincts, dans la solution de l'invention, mais ils remplissent des fonctions communes. Les conteneurs coopèrent via leur barre extérieure horizontale avec le ou les crochets de la platine pour leur accrochage en vue d'être entraînés le long du rail du bras, et les ergots, qui servent au verrouillage du conteneur sur la platine, participent cependant aussi à l'entraînement du conteneur par la platine solidaire du chariot mobile.The hooking and locking means are therefore distinct, in the solution of the invention, but they perform common functions. The containers cooperate via their horizontal outer bar with the hook or hooks of the plate for their attachment with a view to being driven along the rail of the arm, and the lugs, which are used to lock the container on the plate, however also participate in the drive of the container by the plate integral with the mobile carriage.

De préférence, la platine est reliée à rotation au chariot, au moins un vérin permettant de régler le positionnement angulaire relatif du chariot et de la platine. Il est donc possible de piloter de manière fine l'orientation de la platine, et par conséquent du conteneur qui lui est fixé. Le réglage de la position de la platine à l'aide de ce vérin est notamment utilisé en position renversée du conteneur au-dessus de la trémie, comme on le verra plus en détail dans la suite.Preferably, the plate is rotatably connected to the carriage, with at least one jack making it possible to adjust the relative angular positioning of the carriage and of the plate. It is therefore possible to finely control the orientation of the plate, and consequently of the container which is attached to it. Adjusting the position of the plate with the aid of this cylinder is used in particular in the inverted position of the container above the hopper, as will be seen in more detail below.

Selon le système de l'invention, le rail peut comporter au moins une chaîne sans fin entrainée par des moyens moteurs, à laquelle est fixé le chariot. De préférence, il y a deux chaînes continues qui se chargent d'entraîner le chariot, suivant la commande des moyens moteurs.According to the system of the invention, the rail may comprise at least one endless chain driven by motor means, to which the carriage is fixed. Preferably, there are two continuous chains which are responsible for driving the carriage, following the command of the motor means.

En partie haute du dispositif de levage, les glissières du rail de guidage du chariot comportent, dans le second tronçon supérieur du rail du bras de chargement, une butée supérieure d'arrêt du chariot placée en regard de la caisse du véhicule, au contact de laquelle le positionnement du chariot place le conteneur en position renversée. Le conteneur n'est donc renversé que lorsqu'il est du côté de la caisse du véhicule, correctement positionné par rapport aux moyens de vidange, en l'occurrence à la trémie. De préférence, les glissières définissent un trajet d'allure semi-circulaire dans le second tronçon supérieur du rail. L'ouverture du conteneur basculé doit avoir dépassé l'emplacement occupé par le bras de levage, lorsque le chariot est au contact de la butée supérieure, pour que les déchets puissent librement tomber vers le bas de la trémie.In the upper part of the lifting device, the slides of the trolley guide rail comprise, in the second upper section of the rail of the loading arm, an upper trolley stopper placed opposite the body of the vehicle, in contact with which the positioning of the trolley places the container in the overturned position. The container is therefore reversed only when it is on the side of the vehicle body, correctly positioned with respect to the emptying means, in this case the hopper. Preferably, the slideways define a semi-circular path in the second upper section of the rail. The opening of the tipped container must have passed the location occupied by the lifting arm, when the carriage is in contact with the upper stop, so that the waste can freely fall down the hopper.

En fait, en parcourant ledit tronçon supérieur du rail, le conteneur bascule progressivement de sorte à être renversé lorsqu'il est passé de l'autre côté du mât, position dans laquelle il est alors placé bien au-dessus de l'ouverture de la trémie de réception des déchets. La phase de vidange s'effectue donc exclusivement après le passage du sommet, point à partir duquel le basculement s'opère graduellement, jusqu'à ce que, orienté verticalement notamment avec l'aide du ou des vérins reliant le chariot et la platine, le conteneur soit complètement retourné, avec l'ouverture en bas et le fond en haut.In fact, by traversing the said upper section of the rail, the container tilts progressively so as to be overturned when it has passed to the other side of the mast, a position in which it is then placed well above the opening of the waste reception hopper. The emptying phase is therefore carried out exclusively after the passage of the top, point from which the tilting takes place gradually, until, oriented vertically in particular with the help of the jack(s) connecting the carriage and the plate, the container is completely upside down, with the opening at the bottom and the bottom at the top.

Dans l'invention, le support de liaison du rail au châssis est déplaçable par des moyens moteurs entre une position proximale de la caisse du véhicule et une position distante de ladite caisse. Dans la position proximale, le bras de chargement est contenu dans le volume virtuel de la caisse, au niveau de la zone avant comportant la trémie de vidange et le module de lavage.In the invention, the support for connecting the rail to the chassis is movable by motor means between a position proximal to the body of the vehicle and a position remote from said body. In the proximal position, the loading arm is contained in the virtual volume of the box, at the level of the front zone comprising the emptying hopper and the washing module.

Selon l'invention, et pour tirer ensuite parti de la position renversée du conteneur dans le volume du véhicule, le fond du conteneur peut comporter, sur sa face externe, des moyens de fixation à un bras de transfert mobile par rapport au châssis du véhicule et apte à le faire transiter entre une position de vidange au-dessus de la trémie, le conteneur étant fixé au bras de chargement, et une position de lavage dans le module de lavage, le conteneur étant fixé au bras de transfert.According to the invention, and to then take advantage of the inverted position of the container in the volume of the vehicle, the bottom of the container may comprise, on its external face, means for fixing to a transfer arm movable with respect to the chassis of the vehicle. and capable of passing it between an emptying position above the hopper, the container being fixed to the loading arm, and a washing position in the washing module, the container being fixed to the transfer arm.

The invention will now be described in more detail, with reference to the appended figures which represent a non-limiting example of implementation of the invention, and for which:
  • The figure 1 shows, in perspective view, a bio-waste collection vehicle according to the present invention;

En référence à la figure 1, le véhicule 1, en l'occurrence un camion de collecte des déchets, comporte à titre principal, sur un châssis doté d'une cabine de pilotage 10 avant et d'une caisse arrière, une cuve de stockage 2 située vers l'arrière du véhicule 1 et un espace avant comportant, sur une façade latérale du véhicule 1 telle que visible au premier plan de la figure 1, un bras de chargement 3 derrière lequel se trouve un espace fonctionnel de vidange avec une trémie 7 et un module de lavage 8 de conteneurs 6. En fait, ledit espace fonctionnel se développe transversalement entre la cabine 10 et la cuve de stockage 2, de sorte que le module de lavage 8 se trouve au voisinage de la façade latérale opposée du véhicule 1 par rapport à la façade du bras de chargement 3.With reference to the figure 1 , the vehicle 1, in this case a waste collection truck, mainly comprises, on a chassis provided with a front cockpit 10 and a rear body, a storage tank 2 located towards the rear of the vehicle 1 and a front space comprising, on a side facade of the vehicle 1 as visible in the foreground of the figure 1 , a loading arm 3 behind which there is a functional emptying space with a hopper 7 and a washing module 8 of containers 6. In fact, said functional space develops transversely between the cabin 10 and the storage tank 2, so that the washing module 8 is in the vicinity of the opposite side facade of the vehicle 1 with respect to the facade of the loading arm 3.

Ledit bras 3 est composé d'un support de liaison 30 au châssis, d'un rail 4 comportant un premier tronçon principalement d'allure verticale et d'un second tronçon supérieur recourbé vers l'espace de vidange, et d'un chariot 5 guidé et entrainé sur le rail 4 en vue de charger/décharger des conteneurs 6 de bio-déchets disposés sur la voie publique pour les collecter et les redéposer vides et lavés.Said arm 3 is composed of a connecting support 30 to the chassis, a rail 4 comprising a first section which is mainly vertical in appearance and a second upper section curved towards the emptying space, and a carriage 5 guided and trained on the rail 4 in order to load / unload containers 6 of bio-waste placed on the public highway to collect them and redeposit them empty and washed.

Le chariot 5 apparaissant aux figures 2 à 4 comporte une platine 50, munie de moyens d'accrochage et de verrouillage des conteneurs 6, lesquels présentent à leur tour des moyens permettant la mise en œuvre de ces fonctions, montrés en figure 5. Pour être en mesure de coopérer avec une barre horizontale 60 et des orifices 61 - alignés selon un axe parallèle à ladite barre 60 - la platine 50 présente en l'espèce deux crochets 51 de levage et des ergots coulissables 52 (voir en particulier en figure 2). Ces crochets 51 sont à ouverture supérieure, alignés horizontalement et placés au-dessus des deux ergots 52 à déplacement parallèle à la barre 60. Ces ergots 52 sont escamotables, entraînés en sens opposé l'un de l'autre par un dispositif d'escamotage qui permet de gérer leur déplacement entre respectivement une position de verrouillage et une position de déverrouillage.Cart 5 appearing at figures 2 to 4 comprises a plate 50, provided with means for hooking and locking the containers 6, which in turn have means allowing the implementation of these functions, shown in figure 5 . To be able to cooperate with a horizontal bar 60 and orifices 61 - aligned along an axis parallel to said bar 60 - the plate 50 has in this case two lifting hooks 51 and sliding lugs 52 (see in particular in figure 2 ). These hooks 51 have an upper opening, aligned horizontally and placed above the two lugs 52 moving parallel to the bar 60. These lugs 52 are retractable, driven in opposite directions to each other by a retracting device which makes it possible to manage their movement between respectively a locking position and an unlocking position.

Le dispositif d'escamotage est en l'espèce constitué d'un vérin 53 fixé à la platine 50, dont l'extrémité libre de la tige mobile 54 réalise une liaison à rotation avec deux biellettes 55 elles-mêmes reliées à rotation avec les ergots 52. La transformation de mouvement opérée par ce dispositif d'escamotage permet de transformer le déplacement rectiligne selon l'axe de la tige 54 en un mouvement de translation des ergots 52 selon un axe perpendiculaire. Ils coulissent dans des orifices 57 pratiqués dans des parois latérales 58 rapportées à la platine 50, dont les extrémités supérieures comportent des évidements formant notamment lesdits crochets 51 de levage. Les ergots 52 sont donc mobiles entre une position déployée de verrouillage, telle que montrée en figure 2, et une position escamotée de déverrouillage, montrée en figure 4, lorsqu'ils sont coulissés vers l'intérieur, entre les deux plaques 58, et ne dépassent plus à l'extérieur des orifices 57.The retraction device is in this case made up of a cylinder 53 fixed to the plate 50, the free end of the movable rod 54 of which provides a rotational connection with two connecting rods 55 themselves connected in rotation with the lugs 52. The motion transformation effected by this retraction device makes it possible to transform the rectilinear movement along the axis of the rod 54 into a translational movement of the lugs 52 along a perpendicular axis. They slide in orifices 57 made in the side walls 58 attached to the plate 50, the upper ends of which include recesses forming in particular said lifting hooks 51 . The lugs 52 are therefore movable between a deployed locking position, as shown in figure 2 , and a retracted unlocking position, shown in figure 4 , when they are slid inwards, between the two plates 58, and no longer protrude outside the orifices 57.

Le chariot 5 comporte par ailleurs, sur sa face opposée à celle qui porte la platine 50 et les éléments décrits ci-dessus, des moyens d'entrainement et de guidage solidaires d'un châssis 70, plus particulièrement visibles en figure 3. Ainsi, deux plaques latérales 59 fixées au châssis 70 du chariot 5 sont munies de galets 71 permettant le guidage du chariot 5 dans des glissières 41 latérales du rail 4 (voir en figure 4). L'entraînement du chariot 5 s'effectue au moyen de deux chaînes 42 sans fin motorisées auxquelles sont fixées des excroissances 72 perforées dépassant d'ailettes 73 solidaires du châssis 70.The carriage 5 also comprises, on its face opposite that which carries the plate 50 and the elements described above, drive and guide means integral with a frame 70, more particularly visible in picture 3 . Thus, two side plates 59 fixed to the frame 70 of the carriage 5 are provided with rollers 71 allowing the guiding of the carriage 5 in the side slides 41 of the rail 4 (see below). figure 4 ). The drive of the carriage 5 is carried out by means of two motorized endless chains 42 to which are fixed perforated protrusions 72 projecting from fins 73 secured to the frame 70.

La platine 50 est en réalité montée pivotante sur le châssis 70 du chariot 5, au niveau d'un arbre 74 commun. Le positionnement angulaire relatif de la platine 50 et du châssis 70 est contrôlé par des vérins latéraux 75. Ceux-ci sont notamment actionnés lorsque le chariot 5 est en butée supérieure, comme on le verra plus en détail dans la suite.The plate 50 is actually pivotally mounted on the frame 70 of the carriage 5, at the level of a common shaft 74. The relative angular positioning of the plate 50 and the frame 70 is controlled by lateral cylinders 75. These are in particular actuated when the carriage 5 is at the upper stop, as will be seen in more detail below.

Le conteneur, montré en figure 5, comporte sur la face extérieure 62 d'une de ses parois une barre 60 et des orifices coaxiaux 61 dont l'axe est parallèle à celui de ladite barre 60. La barre 60 et les orifices 61 sont en pratique localisés dans un évidement pratiqué dans ladite face 62.The container, shown in figure 5 , comprises on the outer face 62 of one of its walls a bar 60 and coaxial orifices 61 whose axis is parallel to that of said bar 60. The bar 60 and the orifices 61 are in practice located in a recess made in said face 62.

De fait, comme montré aux figures 6 à 8, les glissières 41 permettent de guider le chariot 5 mobile le long du rail 4 selon une trajectoire légèrement courbe, dans le premier tronçon du rail 4 d'allure verticale, à l'aide des galets 71. Les figures 6 à 9 représentent la partie basse dudit premier tronçon, partie au niveau de laquelle s'effectue l'accrochage des conteneurs 6.In fact, as shown in figures 6 to 8 , the slideways 41 make it possible to guide the mobile carriage 5 along the rail 4 according to a slightly curved trajectory, in the first section of the rail 4 of vertical appearance, using the rollers 71. figures 6 to 9 represent the lower part of said first section, part at which the attachment of the containers 6 takes place.

Dans cette partie, le chariot 5 et sa platine 50 sont guidés selon un trajet incliné conduisant les crochets 51 légèrement basculés vers l'extérieur à se diriger vers la barre 60 lorsque le chariot 5 est entraîné vers le haut. Cela signifie bien entendu que le chariot 5 peut partir d'une butée inférieure dans laquelle les crochets 51 de la platine 50 sont positionnés nettement dessous la barre 60 d'accrochage du conteneur 6 posé au sol, comme en figure 1. L'état du chariot 5 en butée inférieure est également la position montrée en figure 5.In this part, the carriage 5 and its plate 50 are guided along an inclined path leading the hooks 51 tilted slightly outwards to move towards the bar 60 when the carriage 5 is driven upwards. This of course means that the carriage 5 can start from a lower stop in which the hooks 51 of the plate 50 are positioned clearly below the hooking bar 60 of the container 6 placed on the ground, as in figure 1 . The state of the carriage 5 at the lower stop is also the position shown in figure 5 .

Il est à noter que le support 30 du bras 3 est lui-même déplaçable horizontalement par exemple au moyen d'un mécanisme à crémaillère 31 (voir en figure 1), de sorte que, par exemple simultanément au déplacement du chariot 5 vers le haut depuis la butée inférieure, le rail 4 peut être rapproché du conteneur 6 posé sur le sol. Ces deux mouvements peuvent aussi être au moins partiellement séquentiels. Les moyens d'accrochage 51 et de verrouillage 52 de la platine 50 se rapprochent dans toutes les hypothèses par en dessous de la barre 60 et des orifices de verrouillage 61 au cours d'une opération de collecte, comme illustré en figure 6. Compte tenu de l'orientation inclinée et légèrement courbe de la partie inférieure des glissières 41, le premier contact de la platine 50 avec le conteneur 6 s'effectue par l'intermédiaire des crochets 51 sur la barre 60, qu'ils accrochent de sorte que le conteneur 6 est entraîné vers le haut, comme illustré en figure 7. A ce stade, toujours du fait de l'inclinaison conférée par les glissières 41, les ergots 52 ne sont pas encore en face des orifices 61, et aucun verrouillage n'est donc encore réalisé ni même possible.It should be noted that the support 30 of the arm 3 is itself movable horizontally, for example by means of a rack mechanism 31 (see below). figure 1 ), so that, for example simultaneously with the movement of the carriage 5 upwards from the lower stop, the rail 4 can be brought closer to the container 6 placed on the ground. These two movements can also be at least partially sequential. The hooking 51 and locking 52 means of the plate 50 approach in all the hypotheses from below the bar 60 and the locking holes 61 during a collection operation, as illustrated in figure 6 . Given the inclined and slightly curved orientation of the lower part of the slides 41, the first contact of the plate 50 with the container 6 takes place via the hooks 51 on the bar 60, which they hook so that the container 6 is driven upwards, as shown in figure 7 . At this stage, still due to the inclination conferred by the slideways 41, the lugs 52 are not yet opposite the orifices 61, and no locking is therefore yet achieved or even possible.

En référence à la figure 8, la platine 50 devient verticale, les ergots 52 se retrouvent dans l'alignement des orifices 61, et le verrouillage peut alors être commandé par le système en actionnant le vérin 53 de sorte que les ergots 52 se retrouvent en position déployée à l'extérieur des parois latérales 58, comme sur la figure 2, et insérés dans lesdits orifices 61.With reference to the figure 8 , the plate 50 becomes vertical, the lugs 52 are found in the alignment of the holes 61, and the locking can then be controlled by the system by actuating the jack 53 so that the lugs 52 are found in the deployed position on the outside side walls 58, as in the figure 2 , and inserted into said orifices 61.

Puis, l'accrochage/verrouillage du conteneur 6 étant réalisé, le chariot 5 poursuit sa remontée vers le second tronçon du rail jusqu'à arriver - après basculement - en contact des butées supérieures des glissières 41 de guidage, comme cela apparaît en figure 9. C'est la position finale dans laquelle le conteneur 6 se retrouve au-dessus d'une trémie 7 de vidange du véhicule 1. Pour que le conteneur 6 soit complètement basculé, c'est-à-dire se retrouve sensiblement à la verticale, l'angle relatif entre la platine 50 et le châssis 70 du chariot est modifié par commande des vérins latéraux 75. En fait, l'état verrouillé du conteneur 6 sur la platine 50 du chariot 5 garantit que le basculement puisse être contrôlé au niveau du second tronçon supérieur arrondi, notamment après passage du sommet où s'effectue le véritable basculement du conteneur 6 permettant sa vidange. Mais le simple positionnement au contact de la butée supérieure, sans actionner les vérins latéraux 75, ne serait pas suffisant pour que le conteneur 6 soit complètement basculé.Then, the hooking/locking of the container 6 being carried out, the carriage 5 continues its ascent towards the second section of the rail until it arrives - after tilting - in contact with the upper stops of the guide rails 41, as appears in figure 9 . This is the final position in which the container 6 finds itself above an emptying hopper 7 of the vehicle 1. For the container 6 to be completely tilted, that is to say to be substantially vertical, the relative angle between the plate 50 and the chassis 70 of the carriage is modified by controlling the side cylinders 75. In fact, the locked state of the container 6 on the plate 50 of the carriage 5 guarantees that the tilting can be controlled at the level of the second rounded upper section, in particular after passing the top where the actual tilting of the container 6 takes place, allowing it to be emptied. But the simple positioning in contact with the upper stop, without actuating the side jacks 75, would not be sufficient for the container 6 to be completely tilted.

L'orientation verticale lorsque le conteneur 6 est basculé, qui n'est pas strictement nécessaire mais préférable pour la vidange, peut cependant s'avérer utile car le fond du conteneur 6 peut comporter, sur sa face externe, des moyens de fixation à un bras de transfert 9 mobile relié au châssis du véhicule 1. Ce bras de transfert 9 permet de faire transiter le conteneur 6 entre une position de vidange au-dessus de la trémie 7, position dans laquelle le conteneur 6 est encore relié au bras 3 de chargement, et une position de lavage dans le module de lavage 8, le conteneur 6 étant alors relié au bras de transfert 9. Il y a donc changement du système de suspension, en position basculée verticale, entre un accrochage d'une part au chariot 5 guidé le long du rail 4 du bras 3 et d'autre part au bras de transfert 9.The vertical orientation when the container 6 is tilted, which is not strictly necessary but preferable for emptying, can however prove to be useful because the bottom of the container 6 can comprise, on its external face, means for fixing to a mobile transfer arm 9 connected to the chassis of the vehicle 1. This transfer arm 9 allows the container 6 to transit between an emptying position above the hopper 7, a position in which the container 6 is still connected to the arm 3 of loading, and a washing position in the washing module 8, the container 6 then being connected to the transfer arm 9. There is therefore a change in the suspension system, in the vertical tilted position, between an attachment on the one hand to the carriage 5 guided along the rail 4 of the arm 3 and on the other hand to the transfer arm 9.

Il est à noter que l'invention ne se limite pas à l'exemple de configuration particulièrement décrit et expliqué en référence aux figures. Cet exemple ne doit être considéré que comme une simple illustration non exhaustive de l'invention. Celle-ci englobe au contraire les variantes notamment de forme, de matériaux, de configuration, etc., entrant dans la portée des revendications.It should be noted that the invention is not limited to the configuration example particularly described and explained with reference to the figures. This example should only be considered as a simple non-exhaustive illustration of the invention. This encompasses, on the contrary, variants in particular of shape, materials, configuration, etc., falling within the scope of the claims.
