Description

[La présente invention entre dans le domaine du traitement des déchets. L'invention s'inscrit plus particulièrement dans le cadre d'un site ou d'une plateforme de tri des déchets domestiques et/ou industriels. L'invention se rapport plus particulièrement à un dispositif de compactage des déchets.[The present invention falls within the field of waste treatment. The invention falls more particularly within the framework of a site or a platform for sorting domestic and / or industrial waste. The invention relates more particularly to a device for compacting waste.

De manière générale, des sites de tri des déchets domestiques et/ou industriels sont communément appelés déchèterie. Ces sites ont été développés pour optimiser le traitement des déchets que ce soit en vue de leur destruction et/ou de leur recyclage.In general, domestic and / or industrial waste sorting sites are commonly called recycling centers. These sites have been developed to optimize the treatment of waste, whether for destruction and / or recycling.

La plupart de ces sites de tri comportent des bennes à déchets qui sont disposées autour d'une plateforme surélevée qui permet aux utilisateurs du site de tri de remplir les bennes par le haut depuis la plateforme. Les différentes bennes qui équipent un tel site de tri sont respectivement destinées à accueillir des déchets triés en fonction de leur nature. Une benne est formée par un espace de chargement délimité inférieurement par une paroi de fond et latéralement par des parois latérales. En général, une benne s'étend longitudinalement entre ses deux extrémités et comporte une conformation de prisme à base rectangulaire dont la face supérieure est ouverte. Cette conformation et des dimensions normalisées permettent son chargement sur le châssis d'un véhicule de transport.Most of these sorting sites have waste bins that are arranged around an elevated platform that allows users of the sorting site to fill the bins from above from the platform. The various skips which equip such a sorting site are respectively intended to receive waste sorted according to their nature. A skip is formed by a loading space delimited below by a bottom wall and laterally by side walls. In general, a bucket extends longitudinally between its two ends and has a prism conformation with a rectangular base, the upper face of which is open. This conformation and standardized dimensions allow it to be loaded onto the chassis of a transport vehicle.

Typiquement, il est possible de trouver dans une déchèterie, une benne dédiée aux résidus végétaux, résidus de bois et dérivés du bois, résidus de carton, résidus métalliques mais aussi des encombrants qui ne rentrent pas forcément dans les autres catégories de déchets etc.Typically, it is possible to find in a recycling center, a dumpster dedicated to plant residues, wood and wood-derived residues, cardboard residues, metal residues but also bulky items that do not necessarily fit into other categories of waste, etc.

Lorsque la benne est pleine, elle est remplacée par une benne vide au niveau de la plateforme. Un transporteur viendra la récupérer afin d'amener le contenu de la benne sur un site de traitement spécifique en fonction de la nature des déchets que la benne contient.When the bucket is full, it is replaced by an empty bucket at the platform level. A transporter will come and collect it in order to bring the contents of the dumpster to a specific treatment site depending on the nature of the waste that the dumpster contains.

En cas de fortes affluences des utilisateurs, il est courant qu'une ou plusieurs bennes se remplissent rapidement. Cependant, la plupart des plateformes de trie disposent, en règle générale, d'un nombre limité de benne sur site. Dans ce contexte, afin d'optimiser les capacités de stockage de chaque benne, l'exploitant du site de tri procède au compactage des déchets dans chaque benne.In the event of heavy influx of users, it is common for one or more skips to fill up quickly. However, most sorting platforms generally have a limited number of tippers on site. In this context, in order to optimize the storage capacities of each skip, the operator of the sorting site compacts the waste in each skip.

A cet effet, il existe actuellement plusieurs types de compacteurs spécifiques de cette application. Ces compacteurs comportent, en général, un bras mécanique à l'extrémité duquel est disposé un rouleau de compactage de déchets. Le bras mécanique permettant de déplacer le rouleau de compactage selon des mouvements longitudinaux de va-et-vient au sein de l'espace de chargement de la benne. Le rouleau de compactage est en général mobile en rotation autour de l'axe longitudinal médian de son tambour.To this end, there are currently several types of compactors specific to this application. These compactors generally comprise a mechanical arm at the end of which is disposed a waste compacting roller. The mechanical arm making it possible to move the compaction roller in longitudinal back-and-forth movements within the loading space of the skip. The compaction roller is generally movable in rotation about the median longitudinal axis of its drum.

Ces compacteurs peuvent être fixes, auquel cas, il est nécessaire de déplacer la benne pour opérer le compactage des déchets. Ceci constitue un inconvénient majeur en termes de gestion du site de tri, puisque cela nécessite, de déplacer temporairement la benne depuis la plateforme vers le compacteur. Par ailleurs, la benne doit être présentée via une de ses extrémités dans l'axe du bras mécanique du compacteur fixe afin que ce dernier puisse compacter les déchets en procédant à des déplacements de va-et-vient du rouleau de compactage.These compactors can be fixed, in which case, it is necessary to move the bucket to operate the compaction of the waste. This constitutes a major drawback in terms of management of the sorting site, since it requires temporarily moving the bucket from the platform to the compactor. Furthermore, the bucket must be presented via one of its ends in the axis of the mechanical arm of the fixed compactor so that the latter can compact the waste by moving the compacting roller back and forth.

En particulier, il est connu dans ce document GB2.261.626 un dispositif de compactage de déchets contenus dans un conteneur, dispositif comportant un bras dont une extrémité est montée mobile verticalement sur un bâti support et portant, à son extrémité opposée, un rouleau de compactage. Celui-ci est prévu apte à plonger dans le conteneur dans lequel il est mis en rotation autour de son axe horizontal et autour d'un axe de pivotement vertical. A cette extrémité du bras portant le rouleau de compactage est rapporté un distributeur hydraulique comportant un corps cylindrique à l'intérieur duquel est monté en rotation autour un arbre d'entrainement pourvu, lui-même, d'un bras support sur lequel est rapporté le rouleau de compactage. Sur l'extrémité supérieure de l'arbre agit un moteur hydraulique pour entraîner en rotation le rouleau de compactage autour de son axe pivotement vertical. Le fonctionnement et le sens d'entrainement de ce moteur est synchronisé avec le sens d'entrainement et le fonctionnement du moteur d'entrainement du rouleau de compactage autour de son axe.In particular, it is known in this document GB2.261.626 a device for compacting waste contained in a container, a device comprising an arm, one end of which is mounted vertically movably on a support frame and carrying, at its opposite end, a compacting roller. This is provided suitable for immersing in the container in which it is rotated about its horizontal axis and about a vertical pivot axis. At this end of the arm carrying the compacting roller is attached a hydraulic distributor comprising a cylindrical body inside which is mounted in rotation around a drive shaft provided, itself, with a support arm on which is attached the compaction roller. On the upper end of the shaft acts a hydraulic motor to drive the compaction roller in rotation around its vertical pivot axis. The operation and the driving direction of this motor is synchronized with the driving direction and the operation of the driving motor of the compacting roller around its axis.

On connait une solution similaire par le document WO 95/25632 qui décrit un dispositif de compactage comportant un châssis support formé par une embase sur laquelle est monté un mat le long duquel peut se déplacer verticalement un bras support. Celui-ci porte à son extrémité un rouleau de compactage destiné à être plongé dans un conteneur à déchets placé en-dessous. Le rouleau de compactage est monté en libre en rotation autour d'un axe vertical sur cette extrémité du bras support. Par ailleurs, intérieurement ce rouleau de compactage accueille un moteur pour son entraînement rotation autour de son axe.We know a similar solution from the document WO 95/25632 which describes a compacting device comprising a support frame formed by a base on which is mounted a mast along which can move vertically a support arm. This carries at its end a compacting roller intended to be immersed in a waste container placed below. The compaction roller is mounted to rotate freely around a vertical axis on this end of the support arm. Moreover, internally this compacting roller accommodates a motor for its rotation drive around its axis.

Des compacteurs mobiles sont également connus de l'état de la technique, le bras mécanique qui porte le rouleau de compactage est alors associé à une cabine de pilotage montée sur un châssis équipé d'un système de traction. Ce type de compacteur permet d'opérer des opérations de compactage depuis le sol. Cependant, le compacteur mobile doit nécessairement se présenter à une extrémité de la benne dans l'axe du bras mécanique afin d'opérer un compactage par des déplacements de va-et-vient longitudinaux du rouleau de compactage.Mobile compactors are also known from the state of the art, the mechanical arm which carries the compacting roller is then associated with a pilot's cabin mounted on a frame equipped with a traction system. This type of compactor allows compaction operations to be carried out from the ground. However, the mobile compactor must necessarily be present at one end of the bucket in the axis of the mechanical arm in order to effect compaction by longitudinal reciprocating movements of the compaction roller.

Les compacteurs mobiles ou fixes présentent des contraintes d'utilisation importante qui nécessite le déplacement des bennes et/ou un positionnement du bras mécanique dans l'axe longitudinal de la benne pour opérer un compactage optimal des déchets. De surcroît, l'acquisition d'un compacteur représente un investissement important pour les exploitants des sites de tri. Cet investissement est d'autant plus important que les exploitants disposent en général de véhicules polyvalents tels que des pelles mécaniques.Mobile or stationary compactors have significant usage constraints which require the movement of the buckets and / or the positioning of the mechanical arm in the longitudinal axis of the bucket in order to achieve optimum compaction of the waste. In addition, the acquisition of a compactor represents a significant investment for the operators of sorting sites. This investment is all the more important as operators generally have multi-purpose vehicles such as mechanical excavators.

Pour répondre à cette problématique, des rouleaux de compactage amovibles d'un bras mécanique ont été développés. Le document EP 2 808 161 décrit en ce sens un rouleau de compactage qui comprend un châssis qui porte un tambour de compactage qui est monté en rotation autour de son axe longitudinal médian. Le châssis s'étend intérieurement au tambour et comporte des moyens moteurs qui entrainent en rotation le tambour. Le châssis comporte un module de connexion à un bras mécanique. Le module de connexion est monté traversant de la paroi cylindrique du tambour. Ce module de connexion est amovible du bras mécanique et possède des moyens de raccordement électrique et/ou hydraulique à ce bras mécanique. Ce rouleau de compactage amovible permet aux exploitants des sites de tri de s'équiper de rouleau de compactage à moindre frais. Ces rouleaux sont compatibles avec l'extrémité d'un bras mécanique d'une pelle mécanique que possède généralement tous les sites de tri. Cependant, ce rouleau de compactage nécessite toujours d'être employés selon des déplacements longitudinaux par va-et-vient au sein de l'espace de chargement d'une benne. Ceci implique que la pelle mécanique portant le rouleau de compactage se présente nécessairement dans l'axe longitudinal de la benne.To respond to this problem, compacting rollers removable from a mechanical arm have been developed. The document EP 2 808 161 describes in this sense a compaction roller which comprises a frame which carries a compaction drum which is mounted in rotation about its median longitudinal axis. The frame extends internally to the drum and comprises motor means which drive the drum in rotation. The chassis includes a module for connection to a mechanical arm. The connection module is mounted through the cylindrical wall of the drum. This connection module is removable from the mechanical arm and has means for electrical and / or hydraulic connection to this mechanical arm. This removable compaction roller allows sorting site operators to equip themselves with a compacting roller at a lower cost. These rollers are compatible with the end of a mechanical arm of a mechanical excavator generally available at all sorting sites. However, this compacting roller still needs to be used in longitudinal movements back and forth within the loading space of a dumpster. This implies that the mechanical shovel carrying the compaction roller is necessarily present in the longitudinal axis of the bucket.

Pour répondre à cette problématique, le document EP 1 253 003 décrit un rouleau de compactage amovible d'une pelle mécanique qui comporte un module de connexion qui porte directement le tambour de manière excentrique. Le module de connexion est monté rotatif par rapport au bras mécanique et intègre un moteur qui au travers d'une transmission conique entraine en rotation, d'une part, l'arbre du tambour selon un premier axe de rotation, et d'autre part, le module de rotation selon un axe perpendiculaire à l'arbre du tambour. Cette conception mécanique génère une double rotation simultanée du rouleau de compactage selon deux axes perpendiculaires l'un à l'autre. Cette double rotation peut être utile lorsque l'on souhaite traiter une benne cylindrique. Néanmoins, étant donné que le rouleau de compactage tourne nécessairement en double rotation, ce type de rouleau ne permet pas de traiter les angles d'une benne à base rectangulaire. De surcroît, compte tenu des contraintes qui s'appliquent sur le rouleau de compactage lors du compactage des déchets, la complexité mécanique de ce système peut générer une usure mécanique prématurée notamment des moyens de transmission coniques.To answer this problem, the document EP 1 253 003 describes a compacting roller removable from a mechanical excavator which comprises a connection module which directly carries the drum eccentrically. The connection module is rotatably mounted relative to the mechanical arm and incorporates a motor which, through a conical transmission, drives in rotation, on the one hand, the shaft of the drum according to a first axis of rotation, and on the other hand , the module of rotation along an axis perpendicular to the drum shaft. This mechanical design generates a simultaneous double rotation of the compaction roller in two axes perpendicular to each other. This double rotation can be useful when you want to treat a cylindrical bucket. However, given that the compaction roller necessarily rotates in double rotation, this type of roller does not allow the angles of a rectangular-based bucket to be processed. In addition, taking into account the constraints which apply to the compaction roller during the compaction of the waste, the mechanical complexity of this system can generate premature mechanical wear, in particular of the conical transmission means.

Au regard des inconvénients de l'état de la technique, la demanderesse a développé une solution technique adaptable à un bras mécanique, cette solution est flexible d'utilisation, robuste, peu couteuse et permet d'optimiser le compactage de déchets contenus dans une benne de toutes formes.In view of the drawbacks of the state of the art, the applicant has developed a technical solution adaptable to a mechanical arm, this solution is flexible in use, robust, inexpensive and makes it possible to optimize the compaction of waste contained in a skip. of all forms.

Les moyens d'orientation permettent d'orienter le tambour de compactage par rapport au module de connexion et, en conséquence d'adapter cette orientation du tambour de compactage, que ce soit en fonction de la forme d'une benne ou du positionnement par rapport à cette dernière de l'engin mécanique portant le rouleau de compactage, ceci dans le but d'arriver à traiter de manière optimisée les déchets que contient une telle benne. De plus, le caractère orientable du tambour de compactage par rapport au module de connexion, contribue à réduire, lors d'une opération de compactage, les déplacements du rouleau de compactage au sein de l'espace de chargement d'une benne à déchets.The orientation means make it possible to orient the compacting drum with respect to the connection module and, consequently to adapt this orientation of the compacting drum, whether it is as a function of the shape of a bucket or of the positioning with respect to to the latter of the mechanical device carrying the compacting roller, with the aim of achieving an optimized treatment of the waste contained in such a bucket. In addition, the orientable nature of the compacting drum with respect to the connection module contributes to reducing, during a compacting operation, the movements of the compacting roller within the loading space of a waste bucket.

The fact that the means act in direct transmission makes it possible to optimize the power of the motor means and to increase the longevity of the motor means.

Selon une troisième caractéristique de l'invention, les moyens d'orientation comportent un actionneur configuré pour entrainer la rotation du châssis par rapport au module de connexion, d'une part, selon un angle compris entre 0° et 90°, et d'autre part, selon deux sens de rotation. Ceci permet d'optimiser le procédé de compactage en s'adaptant à n'importe quel type de benne à déchets.According to a third characteristic of the invention, the orientation means comprise an actuator configured to cause the rotation of the frame relative to the connection module, on the one hand, at an angle between 0 ° and 90 °, and on the other hand, in two directions of rotation. This makes it possible to optimize the compaction process by adapting to any type of waste bucket.

Selon une quatrième caractéristique de l'invention, les moyens d'orientation comportent un actionneur qui entraine de manière excentrique le châssis en rotation autour de son axe de rotation. En particulier, les moyens d'orientation peuvent comporter un vérin, de préférence le vérin est de type hydrauliqueAccording to a fourth characteristic of the invention, the orientation means comprise an actuator which eccentrically drives the frame in rotation about its axis of rotation.

L'invention se rapporte également à un dispositif de compactage d'une benne de déchets comprenant un engin mécanique équipé d'un bras mécanique portant un rouleau de compactage selon l'invention, d'une part, le bras mécanique porte de façon amovible le rouleau de compactage, et d'autre part, le bras mécanique connecte, électriquement et/ou hydrauliquement, le rouleau de compactage au poste de pilotage du dispositif de compactage.The invention also relates to a device for compacting a waste bucket comprising a mechanical machine equipped with a mechanical arm carrying a compacting roller according to the invention, on the one hand, the mechanical arm removably carries the compaction roller, and on the other hand, the mechanical arm connects, electrically and / or hydraulically, the compaction roller to the driving position of the compaction device.

Le procédé se caractérise en ce que, le dispositif de compactage procède au compactage de déchets contenus dans la benne, d'une part, en déplaçant le rouleau de compactage selon une trajectoire crénelée alors que le tambour de compactage est entrainé en rotation, et d'autre part, en actionnant la rotation du châssis du rouleau de compactage afin d'atteindre les angles de la benne tout en limitant la complexité de la trajectoire crénelée.In addition, the invention relates to a method for compacting waste contained in a skip, implementing a compacting device according to the invention. The method is characterized in that, the compaction device proceeds to the compaction of waste contained in the bucket, on the one hand, by moving the compaction roller in a crenellated path while the compaction drum is driven in rotation, and on the other hand, by activating the rotation of the compacting roller frame in order to reach the angles of the bucket while limiting the complexity of the crenellated path.

L'invention concerne un rouleau de compactage 1 de déchets. Le rouleau de compactage 1 selon l'invention est configuré pour être porté par un engin mécanique 2 et en particulier par un bras mécanique 20 de cet engin 2. Ceci est illustré à la figure 6. En effet, comme cela a été précisé dans l'introduction de ce document, les exploitants de site de tri de déchets possèdent généralement des engins mécaniques 2 équipés d'un bras mécanique 20 tels qu'une pelle mécanique, un chariot manuscopique, une chargeuse pelleteuse. L'invention fournit ainsi une solution de compactage qui est configurée pour s'adapter aux équipements matériels que possèdent déjà les exploitants Comme illustré aux figures 1 à 5, le rouleau de compactage 1 comprend un châssis 3. Le châssis 3 supporte notamment un tambour 4 de compactage et un module de connexion 5 à un bras mécanique 20.The invention relates to a waste compaction roller 1. The compaction roller 1 according to the invention is configured to be carried by a mechanical machine 2 and in particular by a mechanical arm 20 of this machine 2. This is illustrated on figure 6 . Indeed, as was specified in the introduction to this document, the operators of waste sorting sites generally have mechanical devices 2 equipped with a mechanical arm 20 such as a mechanical shovel, a manuscopic cart, a loader. backhoe. The invention thus provides a compaction solution which is configured to adapt to the hardware equipment that operators already have. figures 1 to 5 , the compacting roller 1 comprises a frame 3. The frame 3 notably supports a compacting drum 4 and a connection module 5 to a mechanical arm 20.

Le châssis 3 est constitué d'une pièce en étrier 30. Cette pièce en étrier 30 se compose d'une poutrelle centrale 31 équipée à chacune de ses extrémités d'une branche de fixation 32. Les deux branches de fixation 32 s'étendent parallèlement et respectivement selon un axe perpendiculaire de la poutrelle centrale 31. De manière préférentielle, la pièce en étrier 30 est constituée dans un matériau métallique comme l'acier.The frame 3 consists of a stirrup part 30. This stirrup part 30 consists of a central beam 31 equipped at each of its ends with a fixing branch 32. The two fixing branches 32 extend in parallel. and respectively along a perpendicular axis of the central beam 31. Preferably, the stirrup part 30 is made of a metallic material such as steel.

Selon l'invention, les deux branches de fixation 32 supportent respectivement, au travers d'une liaison pivot 33, une extrémité de l'arbre de rotation du tambour 4 de compactage. De fait, le tambour 4 est monté en rotation par rapport châssis 3.According to the invention, the two fixing branches 32 respectively support, through a pivot connection 33, one end of the rotation shaft of the compacting drum 4. In fact, the drum 4 is mounted in rotation with respect to the frame 3.

Comme illustré aux figures 1 et 2, le tambour 4 de compactage s'étend longitudinalement par rapport au châssis 3. En particulier, le tambour 4 s'étend longitudinalement entre les deux branches de fixation 32 du châssis 3.As shown in figures 1 and 2 , the compacting drum 4 extends longitudinally with respect to the frame 3. In particular, the drum 4 extends longitudinally between the two fixing branches 32 of the frame 3.

Le tambour 4 comprend deux extrémités 40 opposées l'une de l'autre. Ainsi, il est également possible de décrire un tambour 4 s'étendant longitudinalement entre ses deux extrémités 40. L'arbre du tambour 4 s'étend selon un axe longitudinal médian A-A du tambour 4. Dans cet exemple, l'arbre du tambour 4 est saillant des extrémités 40 du tambour 4 afin de former la liaison pivot 33 avec chaque branche 32 du châssis 3. L'arbre du tambour 4 n'est pas directement visible sur les figures placées en annexe, cependant il est possible de visualiser une de ses extrémités 41 qui est saillante d'un palier lisse 34 solidaire d'une branche de fixation 32.The drum 4 comprises two ends 40 opposite to each other. Thus, it is also possible to describe a drum 4 extending longitudinally between its two ends 40. The shaft of the drum 4 extends along a median longitudinal axis AA of the drum 4. In this example, the shaft of the drum 4 is protruding from the ends 40 of the drum 4 in order to form the pivot connection 33 with each branch 32 of the frame 3. The shaft of the drum 4 is not directly visible in the figures placed in the appendix, however it is possible to visualize one of its ends 41 which project from a sliding bearing 34 integral with a fixing branch 32.

Dans l'exemple illustré aux figures 1 à 5, le tambour 4 est constitué d'un cylindre droit à base circulaire. Cette forme est peu couteuse et robuste d'un point de vue mécanique. Néanmoins, il est possible que le tambour 4 soit constitué d'un cylindre droit à base polygonale telle que triangulaire, rectangulaire ou hexagonale etc. Il est également possible d'utiliser un cylindre bombé ou une forme conique simple ou double.In the example shown in figures 1 to 5 , the drum 4 consists of a right cylinder with a circular base. This form is inexpensive and robust from a mechanical point of view. However, it is possible that the drum 4 consists of a straight cylinder with a polygonal base such as triangular, rectangular or hexagonal etc. It is also possible to use a domed cylinder or a single or double conical shape.

En complément, le tambour 4 de compactage peut avantageusement comporter des dents 42. Les dents 42 sont saillantes de la paroi du tambour 4. Les dents permettent d'optimiser le compactage en déchiquetant les déchets contenus dans l'espace de chargement d'une benne 6. Les dents 42 peuvent être disposées selon un agencement déterminé ou de manière aléatoire. Dans cet exemple, les dents 42 sont disposées sur le tambour 4 selon cinq rangées. Sur une même rangée, les dents 42 sont disposées à un intervalle régulier et leur disposition peut être décalée sur deux rangées adjacentes.In addition, the compacting drum 4 can advantageously include teeth 42. The teeth 42 protrude from the wall of the drum 4. The teeth make it possible to optimize the compaction by shredding the waste contained in the loading space of a skip. 6. The teeth 42 may be arranged in a predetermined arrangement or in a random manner. In this example, the teeth 42 are arranged on the drum 4 in five rows. On the same row, the teeth 42 are arranged at a regular interval and their arrangement can be shifted over two adjacent rows.

En complément, l'orientation des dents 42 peut varier comme cela est illustré aux figures 1 à 5. A titre indicatif, la figure 1 montre que les deux rangées extrêmales adjacentes de chaque extrémité 40 du tambour 4, mais aussi la rangée centrale, comportent des dents 42 qui s'étendent selon un axe perpendiculaire de l'arbre du tambour 4. Par ailleurs, les deux rangées, situées entre une rangée extrêmale et la rangée centrale, comportent des dents 42 qui sont orientées de manière oblique.In addition, the orientation of the teeth 42 may vary as illustrated in figures 1 to 5 . As an indication, the figure 1 shows that the two adjacent end rows of each end 40 of the drum 4, but also the central row, comprise teeth 42 which extend along a perpendicular axis of the shaft of the drum 4. Furthermore, the two rows, located between an end row and the central row, comprise teeth 42 which are oriented obliquely.

Il est à noter que le châssis 3 peut comprendre une grille 35 qui s'étend depuis la poutrelle centrale 31 en direction du tambour 4. La grille 35 est constituée par des couteaux 36 qui sont disposés à une distance déterminée les uns et des autres. Les couteaux 36 sont répartis entre chaque extrémité de la poutrelle centrale 31. En complément, les rangées de dents 42 sont disposées de manière à passer au travers de la grille 35 montée sur le châssis 3. Lorsqu'une dent 42 passe au travers de la grille 35 elle peut se libérer de tout déchet qui serait emportés dans le mouvement de rotation du tambour 4. La coopération entre la grille 35 et les 42 contribue à prévenir l'insertion de déchets entre le tambour 4 et le châssis qui peut conduire dans certains cas au blocage du tambour 4, voir à la détérioration du rouleau de compactage 1.It should be noted that the frame 3 may include a grid 35 which extends from the central beam 31 in the direction of the drum 4. The grid 35 is formed by knives 36 which are arranged at a determined distance from each other. The knives 36 are distributed between each end of the central beam 31. In addition, the rows of teeth 42 are arranged so as to pass through the grid 35 mounted on the frame 3. When a tooth 42 passes through the grid 35 it can free itself from any waste that would be carried away in the rotational movement of the drum 4. The cooperation between the grid 35 and the 42 helps to prevent the insertion of waste between the drum 4 and the frame which can lead in some In the event of blockage of drum 4, see damage to compaction roller 1.

De manière optionnelle, le tambour 4 peut comprendre une bride 43 à chacune de ses extrémités 40. Cette bride 43 est plus longue que les dents 42 du tambour 4. De fait, il est possible de poser le rouleau de compactage 1 au sol ou sur un support sans endommager les dents 42 et le tambour 4.Optionally, the drum 4 can include a flange 43 at each of its ends 40. This flange 43 is longer than the teeth 42 of the drum 4. In fact, it is possible to place the compacting roller 1 on the ground or on the ground. a support without damaging the teeth 42 and the drum 4.

Le rouleau de compactage 1 comporte des moyens moteurs 7 configurés pour entrainer en rotation le tambour 4 de compactage. Le tambour 4 est entrainé en rotation autour de son axe longitudinal médian A-A. Dans cet exemple, les moyens moteurs 7 sont supportés par le châssis 3.The compaction roller 1 comprises motor means 7 configured to drive the compaction drum 4 in rotation. The drum 4 is driven in rotation around its median longitudinal axis A-A. In this example, the motor means 7 are supported by the frame 3.

Comme cela est illustré aux figures 1 à 5, les moyens moteurs 7 sont disposés à au moins une extrémité 41 de l'arbre de rotation du tambour 4 de compactage. Les moyens moteurs 7 sont configurés pour entrainer le tambour 4 en rotation selon deux sens de rotation. De préférence, l'invention utilise un moteur à entrainement direct. Ce moteur peut être hydraulique et comporter un axe creux monté à une extrémité 41 de l'arbre de rotation du tambour 4. Néanmoins, bien qu'il soit moins fiable, il est également possible d'utiliser un moteur hydraulique à axe sortant qui nécessite une transmission. Les moteurs électriques sont moins puissants mais pourraient également être envisagés pour équiper le rouleau de compactage 1.As illustrated in figures 1 to 5 , the motor means 7 are arranged at at least one end 41 of the rotation shaft of the compacting drum 4. The motor means 7 are configured to drive the drum 4 in rotation in two directions of rotation. Preferably, the invention uses a direct drive motor. This motor can be hydraulic and include a hollow shaft mounted at one end 41 of the rotation shaft of the drum 4. However, although it is less reliable, it is also possible to use a hydraulic motor with an outgoing shaft which requires a transmission. Electric motors are less powerful but could also be considered to equip the compaction roller 1.

Le rouleau de compactage 1 comporte un module de connexion 5 qui est configuré pour être connecté de manière amovible à un bras mécanique 20. A cet effet, le module de connexion 5 comprend un connecteur mécanique 50 qui est configuré pour être connecté de manière amovible à un bras mécanique 20. De plus, le module de connexion comprend des moyens de raccordement électrique et/ou hydraulique à un bras mécanique 20. Les moyens de raccordement électrique et/ou hydraulique permettent d'alimenter en énergie notamment les moyens moteurs 7 et ainsi de piloter depuis l'engin mécanique 2 l'actionnement du tambour 4.The compaction roller 1 comprises a connection module 5 which is configured to be removably connected to a mechanical arm 20. For this purpose, the connection module 5 comprises a mechanical connector 50 which is configured to be removably connected to a mechanical arm 20. In addition, the connection module comprises means for electrical and / or hydraulic connection to a mechanical arm 20. The electrical and / or hydraulic connection means make it possible to supply energy in particular to the motor means 7 and thus to control from the mechanical device 2 the actuation of the drum 4.

Dans cet exemple, le module de connexion 5 comporte au moins une platine 51 qui est assemblée au châssis 3 selon une liaison pivot. En particulier, la platine 51 forme une liaison pivot avec un arbre solidaire du châssis 3. Cet arbre s'étend selon un axe B-B perpendiculaire à la poutrelle centrale 31 (illustré aux figures 1 et 2). De fait, l'axe B-B de l'arbre du châssis 3 est perpendiculaire à l'axe longitudinal médian A-A du tambour 4. Ainsi, le châssis 3 est monté rotatif par rapport au module de connexion 5 selon un axe B-B de rotation qui est perpendiculaire de l'axe longitudinal médian A-A du tambour 4.In this example, the connection module 5 comprises at least one plate 51 which is assembled to the frame 3 in a pivot connection. In particular, the plate 51 forms a pivot connection with a shaft integral with the frame 3. This shaft extends along an axis BB perpendicular to the central beam 31 (illustrated in figures 1 and 2 ). In fact, the axis BB of the shaft of the frame 3 is perpendicular to the median longitudinal axis AA of the drum 4. Thus, the frame 3 is mounted to rotate relative to the connection module 5 along an axis BB of rotation which is perpendicular to the median longitudinal axis AA of the drum 4.

Comme illustrée aux figures 1 à 5, la platine 51 du module de connexion 5 peut être prolongée par un cylindre 52 lui-même solidaire d'une seconde platine 53. Ce type de module de connexion 5 est extrêmement robuste mécaniquement. En ce sens, au regard des grandes contraintes mécaniques qui s'appliquent sur le rouleau de compactage 1 lors d'une opération de compactage, ce module de connexion 5 est particulièrement adapté pour supporter ces contraintes.As illustrated in figures 1 to 5 , the plate 51 of the connection module 5 can be extended by a cylinder 52 which is itself integral with a second plate 53. This type of connection module 5 is extremely robust mechanically. In this sense, in view of the great mechanical stresses which apply to the compaction roller 1 during a compaction operation, this connection module 5 is particularly suitable for withstanding these stresses.

En pratique, le connecteur mécanique 50 est configuré pour être associé à une attache mécanique afin de monter le rouleau de compactage 1 sur un bras mécanique 20. A titre informatif, une telle attache peut comprendre deux flasques parallèles l'un à l'autre et maintenus en position par des entraxes. Dans ce contexte, les dimensions du connecteur mécanique 50 peuvent varier en fonction des dimensions du bras mécanique 20 sur lequel l'exploitant souhaite monter le rouleau de compactage 1.In practice, the mechanical connector 50 is configured to be associated with a mechanical attachment in order to mount the compaction roller 1 on a mechanical arm 20. For information, such an attachment may include two flanges parallel to one another and maintained in position by centers. In this context, the dimensions of the mechanical connector 50 may vary depending on the dimensions of the mechanical arm 20 on which the operator wishes to mount the compaction roller 1.

Selon l'invention, le rouleau de compactage 1 comprend des moyens d'orientation 8. Les moyens d'orientation 8 sont configurés pour orienter le châssis 3 dans plusieurs positions angulaires différentes par rapport au module de connexion 5.According to the invention, the compacting roller 1 comprises orientation means 8. The orientation means 8 are configured to orient the frame 3 in several different angular positions with respect to the connection module 5.

Comme cela est illustré aux figures 3 à 5, les moyens d'orientation 8 comportent un actionneur 80 qui actionne, la rotation du châssis 3 par rapport au module de connexion 5, selon deux sens de rotation. Selon ces deux sens de rotation, l'actionneur 80 peut faire prendre au châssis une multitude de positions radiales. En particulier, l'actionneur 80 peut faire varier la position angulaire du châssis 3 par rapport au module de connexion 5 selon un angle θ comprise entre 0° à 90° dans les deux sens de rotation. L'actionneur 80 peut également faire varier la position du châssis 3 par rapport au module de connexion 5 selon une plage radiale plus restreinte, l'angle θ d'orientation peut être compris entre 0° à 60° dans les deux sens de rotation. Selon une troisième plage plus restreinte, la position angulaire du châssis 3 par rapport au module de connexion 5 peut varier selon un angle θ comprise entre 0° à 40° dans les deux sens de rotation.As illustrated in figures 3 to 5 , the orientation means 8 comprise an actuator 80 which actuates the rotation of the frame 3 relative to the connection module 5, in two directions of rotation. According to these two directions of rotation, the actuator 80 can cause the frame to assume a multitude of radial positions. In particular, the actuator 80 can vary the angular position of the frame 3 relative to the connection module 5 at an angle θ of between 0 ° to 90 ° in both directions of rotation. The actuator 80 can also vary the position of the frame 3 relative to the connection module 5 over a more restricted radial range, the orientation angle θ can be between 0 ° to 60 ° in both directions of rotation. According to a third more restricted range, the angular position of the frame 3 with respect to the module of connection 5 can vary at an angle θ between 0 ° to 40 ° in both directions of rotation.

Dans l'exemple illustré à la figure 3, l'angle θ est définit par rapport à un axe repère C-C qui est pris lorsque le châssis est en position de repos. Dans cette position, l'axe repère C-C correspond à l'axe médian transversal du tambour 4 sur lequel la rangée centrale de dents 42 se situe.In the example shown in figure 3 , the angle θ is defined with respect to a reference axis CC which is taken when the frame is in the rest position. In this position, the reference axis CC corresponds to the transverse median axis of the drum 4 on which the central row of teeth 42 is located.

Dans l'exemple de la figure 4, le châssis 3 a été tourné vers la gauche selon un angle θ d'une valeur de 30° par rapport à l'axe repère C-C. La mesure de l'angle θ est prise, d'une part, par rapport à l'axe repère C-C, et d'autre part, vis-à-vis d'un axe de déplacement D-D qui passe par l'axe médian transversal du tambour 4. Afin d'obtenir une mesure constante de l'angle θ, l'axe de déplacement D-D est définit par l'axe médian transversal du tambour 4. Dans le cas de la figure 3, l'axe de déplacement D-D se superpose à l'axe repère C-C, l'angle θ est alors nul. De façon arbitraire, il est possible de définir que la rotation du châssis 3 vers la gauche fournit un déplacement radial négatif par rapport l'axe repère C-C. A l'inverse, la rotation du châssis 3 vers la droite fournit un déplacement radial positif par rapport l'axe repère C-C. De fait, l'angle θ de la figure 4 possède une valeur de -30°.In the example of figure 4 , the frame 3 has been turned to the left at an angle θ by a value of 30 ° with respect to the reference axis CC. The measurement of the angle θ is taken, on the one hand, with respect to the reference axis CC, and on the other hand, with respect to a displacement axis DD which passes through the transverse median axis of the drum 4. In order to obtain a constant measurement of the angle θ, the displacement axis DD is defined by the transverse median axis of the drum 4. In the case of the figure 3 , the displacement axis DD is superimposed on the reference axis CC, the angle θ is then zero. Arbitrarily, it is possible to define that the rotation of the frame 3 to the left provides a negative radial displacement with respect to the reference axis CC. Conversely, the rotation of the frame 3 to the right provides a positive radial displacement with respect to the reference axis CC. In fact, the angle θ of the figure 4 has a value of -30 °.

A l'inverse, dans l'exemple de la figure 5, le châssis 3 a été tourné vers la droite selon un angle θ d'une valeur de 30° par rapport à l'axe repère C-C. On peut définir l'orientation du châssis selon un angle θ de + 30°.Conversely, in the example of figure 5 , the frame 3 has been turned to the right at an angle θ by a value of 30 ° with respect to the reference axis CC. The orientation of the frame can be defined according to an angle θ of + 30 °.

Comme illustré aux figures 1 à 5, l'actionneur 80 entraine de manière excentrique la rotation du châssis 3 autour de l'axe de rotation B-B.As shown in figures 1 to 5 , the actuator 80 eccentrically drives the rotation of the frame 3 around the axis of rotation BB.

Dans ce contexte, les moyens d'orientation 8 peuvent comporter un bras mécanique comme actionneur 80. De préférence, le bras mécanique est constitué par un vérin. Compte tenu des contraintes mécaniques qui peuvent s'appliquer sur le rouleau de compactage 1, le vérin est préférentiellement choisi de type hydraulique double effet. Cependant, il est également possible d'utiliser un vérin hydraulique rotatif, un vérin électrique ou encore un moteur électrique à engrenage. Avantageusement, un actionneur 80 excentrique présente une résistance mécanique souvent supérieure à un actionneur axial, tel qu'un vérin rotatif à pivot intégré, et possède également un coût de fabrication moins onéreux.In this context, the orientation means 8 may include a mechanical arm as an actuator 80. Preferably, the mechanical arm is constituted by a jack. Taking into account the mechanical constraints which may be applied to the compacting roller 1, the jack is preferably chosen of the double-acting hydraulic type. However, it is also possible to use a rotary hydraulic cylinder, an electric cylinder or even an electric gear motor. Advantageously, an eccentric actuator 80 has a mechanical strength which is often greater than an axial actuator, such as a rotary actuator with integrated pivot, and also has a less expensive manufacturing cost.

Dans l'exemple illustré aux figures 1 à 5, l'actionneur 80 comprend une première extrémité 81 solidaire du châssis 3. Ici, la première extrémité 81 de l'actionneur 80 est montée en rotation, via un axe, avec une pièce en étrier 82 solidaire du châssis 3. La pièce en étrier 82 porte cet axe qui s'étend parallèlement à l'axe de rotation B-B du châssis 3. Plus précisément, la pièce en étrier 82 est montée sur un support 36 déporté par rapport à la poutrelle centrale 31. Le support 36 est disposé dans le prolongement de la face supérieure de la poutrelle 31. Dans cet exemple, la première extrémité 81 de l'actionneur 80 est disposée à l'extrémité libre du cylindre du vérin. Le caractère déporté du point de fixation de la première extrémité 81 de l'actionneur permet d'augmenter la course de l'actionneur 80 excentré. De fait, le châssis 3 dispose d'une plus grande plage d'orientation par rapport au module de connexion 5.In the example shown in figures 1 to 5 , the actuator 80 comprises a first end 81 integral with the frame 3. Here, the first end 81 of the actuator 80 is mounted in rotation, via an axis, with a stirrup piece 82 integral with the frame 3. The stirrup part 82 carries this axis which extends parallel to the axis of rotation BB of the frame 3. More precisely, the stirrup part 82 is mounted on a support 36 offset with respect to the central beam 31. The support 36 is disposed in the extension of the upper face of the beam 31. In this example, the first end 81 of the actuator 80 is disposed at the free end of the cylinder of the jack. The offset nature of the fixing point of the first end 81 of the actuator makes it possible to increase the stroke of the eccentric actuator 80. In fact, the chassis 3 has a greater range of orientation compared to the connection module 5.

L'actionneur 80 comporte une seconde extrémité 83 qui est solidaire du module de connexion 5. La seconde extrémité 83 est aussi montée en rotation, via un axe, entre deux oreilles 84 solidaires du module de connexion 5. Dans cet exemple, les deux oreilles 84 sont saillantes du cylindre 51. L'axe qui est porté par les deux oreilles 84 s'étend parallèlement à l'axe de rotation B-B du châssis 3. La seconde extrémité 83 correspond à l'extrémité libre de la tige de l'actionneur 80. De manière connue, la tige est configurée pour coulisser dans le cylindre l'actionneur 80.The actuator 80 comprises a second end 83 which is integral with the connection module 5. The second end 83 is also mounted in rotation, via an axis, between two ears 84 which are integral with the connection module 5. In this example, the two ears 84 protrude from the cylinder 51. The axis which is carried by the two ears 84 extends parallel to the axis of rotation BB of the frame 3. The second end 83 corresponds to the free end of the rod of the actuator 80. In known manner, the rod is configured to slide the actuator 80 in the cylinder.

Selon cette configuration, l'actionneur 80 est monté en excentrique entre le support 36 solidaire du châssis 3 et les oreilles 84 solidaires du module de connexion 5. Toujours selon cette configuration, lorsque le bras mécanique est actionné, le châssis 3 est entrainé en rotation par rapport au module de connexion 5. Cette rotation du châssis entraine une rotation du tambour 4 de compactage selon un axe B-B perpendiculaire à son arbre de rotation. Il est ainsi possible d'orienter radialement le tambour 4 afin de traiter tous types de bennes 6 qu'elle soit de section circulaire ou polygonale.According to this configuration, the actuator 80 is mounted eccentrically between the support 36 integral with the frame 3 and the ears 84 integral with the connection module 5. Still according to this configuration, when the mechanical arm is actuated, the frame 3 is driven in rotation. relative to the connection module 5. This rotation of the frame causes rotation of the compacting drum 4 along an axis BB perpendicular to its rotation shaft. It is thus possible to radially orient the drum 4 in order to treat all types of buckets 6, whether of circular or polygonal section.

Il est à noter que dans l'exemple des figures 3 à 5, l'axe repère C-C de mesure de l'angle θ d'orientation du châssis 3 est en permanence aligné avec l'axe que portent les deux oreilles 84. Cet axe constitue le point de fixation de l'actionneur 80 sur le module de connexion 5.Note that in the example of figures 3 to 5 , the reference axis CC for measuring the angle θ of orientation of the frame 3 is permanently aligned with the axis carried by the two ears 84. This axis constitutes the point of attachment of the actuator 80 on the control module. connection 5.

Dans l'exemple de la figure 3, l'angle θ d'orientation du châssis 3 est nul alors que la tige du vérin se trouve à mi-course. Ceci constitue la position de repos du châssis 3.In the example of figure 3 , the angle θ of orientation of the frame 3 is zero while the cylinder rod is at halfway. This constitutes the rest position of the chassis 3.

Dans le cas de la figure 4, l'angle θ d'orientation du châssis 3 possède une valeur de -30° et la tige du vérin est complètement déployée. A l'inverse, à la figure 5, l'angle θ d'orientation du châssis 3 possède une valeur + 30°, alors que la tige du vérin est complètement rétractée.In the case of figure 4 , the orientation angle θ of the frame 3 has a value of -30 ° and the cylinder rod is fully extended. Conversely, at the figure 5 , the orientation angle θ of the frame 3 has a value of + 30 °, while the cylinder rod is fully retracted.

En complément, lorsque le vérin est actionné, il est possible de régler l'orientation du châssis 3 par rapport au module de connexion 5 à un degré de rotation près. En conséquence, le châssis 3 peut avantageusement prendre une multitude de position entre les positions radiales -90° et + 90° en fonction des besoins de l'opérateur. Ce qui correspond à une orientation de 180° du châssis 3 ou une orientation selon un angle θ de 90° dans deux sens de rotation opposés.In addition, when the jack is actuated, it is possible to adjust the orientation of the frame 3 relative to the connection module 5 to within a degree of rotation. Consequently, the frame 3 can advantageously take a multitude of positions between radial positions -90 ° and + 90 ° depending on the operator's needs. This corresponds to an orientation of 180 ° of the frame 3 or an orientation at an angle θ of 90 ° in two opposite directions of rotation.

Dans le cas d'une benne 6 de section rectangulaire, l'orientation radiale du tambour 4 permet de traiter l'espace de chargement de la benne 6 en positionnant le bras mécanique 20 portant le rouleau de compactage 1 selon l'axe longitudinal de la benne 6 comme les rouleaux de compactage de l'état de la technique. Toutefois, comme illustré à la figure 6, le bras mécanique 20 peut être présenté latéralement par rapport aux parois de la benne 6. En ce sens, le caractère radialement orientable du rouleau de compactage 1 permet une plus grande flexibilité d'utilisation pour les exploitants d'un site de tri de déchets.In the case of a bucket 6 of rectangular section, the radial orientation of the drum 4 makes it possible to treat the loading space of the bucket 6 by positioning the mechanical arm 20 carrying the compacting roller 1 along the longitudinal axis of the bucket 6 like the compacting rollers of the state of the art. However, as shown in figure 6 , the mechanical arm 20 can be presented laterally with respect to the walls of the skip 6. In this sense, the radially orientable nature of the compaction roller 1 allows greater flexibility of use for the operators of a waste sorting site. .

Comme illustré à la figure 6, l'invention concerne également un dispositif de compactage 9 pour une benne 6 de déchets. Le dispositif de compactage 9 comprend un engin mécanique 2 équipé d'un bras mécanique 20 qui porte un rouleau de compactage 1 selon l'invention. Le bras mécanique 20 porte de façon amovible le rouleau de compactage 1. Le bras mécanique 20 peut comporter deux segments de bras liés l'un à l'autre par une articulation selon un axe. L'articulation entre les deux segments de bras permet de gérer l'allonge du bras mécanique 20. Dans cette configuration, un segment de bras porte le rouleau de compactage 1 alors que l'autre segment est relié à l'engin mécanique 2 selon une articulation deux axes. Un premier axe de l'articulation permet de gérer l'inclinaison du bras mécanique 20 par rapport à l'engin mécanique 2, le second axe de l'articulation permet d'orienter radialement le bras mécanique 20.As shown in figure 6 , the invention also relates to a compacting device 9 for a dumpster 6 of waste. The compacting device 9 comprises a mechanical machine 2 equipped with a mechanical arm 20 which carries a compacting roller 1 according to the invention. The mechanical arm 20 removably carries the compaction roller 1. The mechanical arm 20 may include two arm segments linked to each other by an articulation along an axis. The articulation between the two arm segments makes it possible to manage the extension of the mechanical arm 20. In this configuration, one arm segment carries the compaction roller 1 while the other segment is connected to the mechanical device 2 according to a two-axis articulation. A first axis of the articulation makes it possible to manage the inclination of the mechanical arm 20 relative to the mechanical device 2, the second axis of the articulation makes it possible to orient the mechanical arm 20 radially.

En complément, le bras mécanique 20 connecte, électriquement et/ou hydrauliquement, le rouleau de compactage 1 au poste de pilotage 21 du dispositif de compactage 1. L'utilisateur du dispositif de compactage 9 peut alors piloter le bras mécanique 20 et le rouleau de compactage 1 pour opérer un procédé de compactage d'une benne 6 de déchets.In addition, the mechanical arm 20 connects, electrically and / or hydraulically, the compaction roller 1 to the pilot station 21 of the compaction device 1. The user of the compaction device 9 can then control the mechanical arm 20 and the compaction roller. compacting 1 to operate a method of compacting a bucket 6 of waste.

L'invention se rapporte également à un procédé de compactage d'une benne de déchets qui met en œuvre le dispositif de compactage 9.The invention also relates to a method of compacting a waste bucket which uses the compacting device 9.

Ce procédé est illustré à la figure 6, le procédé comporte une opération de compactage au travers d'un positionnement latéral de l'engin mécanique 2 par rapport à l'axe longitudinal de la benne 6. Le déplacement du rouleau de compactage 1 au sein de l'espace de chargement de la benne 6 est opéré selon une trajectoire crénelée. Cette trajectoire est illustrée par une flèche au sein de l'espace de chargement de la benne 6. A chaque angle de la trajectoire crénelée le tambour 4 du rouleau de compactage 1 peut être orienter pour atteindre les angles de l'espace de chargement de la benne 6. A cet effet, l'utilisateur actionne les moyens d'orientation 8 de façon à faire tourner le châssis 3 par rapport au module de connexion 5. Toutefois, l'invention permet également de traiter une benne 6 à base rectangulaire selon un procédé de déplacement de va-et-vient longitudinaux comme cela est décrit dans l'état de l'art. 6This process is illustrated in figure 6 , the method comprises a compacting operation through a lateral positioning of the mechanical machine 2 with respect to the longitudinal axis of the bucket 6. The displacement of the compacting roller 1 within the loading space of the bucket 6 is operated along a crenellated path. This trajectory is illustrated by an arrow within the loading space of the bucket 6. At each angle of the crenellated trajectory the drum 4 of the compacting roller 1 can be oriented to reach the angles of the loading space of the dumpster 6. For this purpose, the user actuates the orientation means 8 so as to rotate the frame 3 with respect to the connection module 5. However, the The invention also makes it possible to treat a bucket 6 with a rectangular base according to a method for moving back and forth longitudinally as described in the state of the art. 6

Plus particulièrement dans l'exemple de la figure 6, les deux dispositifs de compactage 9 sont disposé en surplomb par rapport à la benne 6 à déchets. En effet, les deux dispositifs de compactage 9 compactent les déchets depuis une plateforme A qui surplombe les bennes 6 à déchets reposant en contrebas par exemple au sol B. Avantageusement, la possibilité d'orienter radialement le rouleau de compactage 1 par rapport au bras mécanique 20 permet de procédé au compactage des déchets contenus dans une benne 6 dans un environnement encombré et/ou en surplomb de la benne 6. L'intérêt de procédé au compactage en surplomb de la benne 6, par exemple, depuis une plateforme A, donne un point de vue sur les déchets contenus dans la benne 6. Ceci permet d'optimiser le compactage. Avantageusement, la possibilité de faire évoluer l'orientation radiale du rouleau de compactage 1 par rapport au bras mécanique 20 auquel le rouleau de compactage est fixé, permet de traiter tous types de benne 6 quelque soit le positionnement de l'engin mécanique 2 ou du bras mécanique 20 par rapport à la benne 6.More particularly in the example of figure 6 , the two compacting devices 9 are arranged overhanging with respect to the dumpster 6 for waste. Indeed, the two compacting devices 9 compact the waste from a platform A which overhangs the waste bins 6 resting below, for example on the ground B. Advantageously, the possibility of orienting the compacting roller 1 radially relative to the mechanical arm 20 allows the method of compacting the waste contained in a bucket 6 in a congested environment and / or overhanging the bucket 6. The interest of the method of compacting overhanging the bucket 6, for example, from a platform A, gives a point of view on the waste contained in the bucket 6. This makes it possible to optimize the compaction. Advantageously, the possibility of changing the radial orientation of the compaction roller 1 relative to the mechanical arm 20 to which the compaction roller is attached, makes it possible to treat all types of bucket 6 regardless of the positioning of the mechanical device 2 or of the mechanical arm 20 in relation to the bucket 6.

Le procédé comprend une opération de déplacement du rouleau de compactage 1 selon une trajectoire crénelée alors que le tambour 4 de compactage est entrainé en rotation. Cette opération de déplacement du rouleau de compactage 1 est opérée à l'aide des différentes articulations du bras mécanique 20. De surcroit, l'opérateur peut inverser le sens de rotation du tambour 4 de compactage s'il rencontre des difficultés pour compacter les déchets.The method comprises an operation of moving the compacting roller 1 along a crenellated path while the compacting drum 4 is rotated. This operation of moving the compacting roller 1 is carried out using the various articulations of the mechanical arm 20. In addition, the operator can reverse the direction of rotation of the compacting drum 4 if he encounters difficulties in compacting the waste. .

En outre, lors du déplacement du rouleau de compactage 1, la rotation du châssis 3 du rouleau de compactage 1 peut être actionnée afin d'atteindre les angles de la benne 6 tout en limitant la complexité de la trajectoire crénelée.In addition, during the movement of the compaction roller 1, the rotation of the frame 3 of the compaction roller 1 can be actuated in order to reach the angles of the bucket 6 while limiting the complexity of the crenellated path.
