Definitions
- 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.
- sorting sites for domestic and/or industrial waste are commonly called waste collection centers. These sites have been developed to optimize the processing of waste, whether for destruction and/or recycling.
- a skip is formed by a loading space delimited below by a bottom wall and laterally by side walls.
- a bucket extends longitudinally between its two ends and has a conformation of prism 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.
- compactors For this purpose, there are currently several types of compactors specific to this application. These compactors generally comprise a mechanical arm at the end of which is placed a roller for compacting waste. The mechanical arm allowing the compaction roller to be moved along longitudinal back-and-forth movements within the loading space of the skip.
- the compacting roller is generally mobile in rotation around the median longitudinal axis of its drum.
- a device for compacting waste contained in a container comprising an arm, one end of which is vertically movably mounted on a support frame and carrying, at its opposite end, a compacting roller according to the preamble of claim 1.

- Mobile compactors are also known from the state of the art, the mechanical arm which carries the compacting roller is then associated with a control 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 to-and-fro movements of the compacting roller.
- Mobile or stationary compactors have significant operating constraints which require the displacement of the skips and/or positioning of the mechanical arm in the longitudinal axis of the skip to operate an optimal compaction of the waste.
- acquisition of a compactor represents a major investment for sorting site operators. This investment is all the more important since operators generally have multi-purpose vehicles such as mechanical shovels.

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, sorting sites for domestic and/or industrial waste are commonly called waste collection centers. These sites have been developed to optimize the processing 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 a raised platform that allows users of the sorting site to fill the bins from above from the platform. The different skips that equip such a sorting site are respectively intended to accommodate waste sorted according to its 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 conformation of prism 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 residues and wood derivatives, 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 dumpster is full, it is replaced by an empty dumpster at platform level. A carrier will pick it up to bring the contents of the dumpster to a specific treatment site depending on the nature of the waste 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 large influxes of users, it is common for one or more dumpsters to fill up quickly. However, most sorting platforms generally have a limited number of skips on site. In this context, in order to optimize the storage capacities of each skip, the sorting site operator 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.For this purpose, there are currently several types of compactors specific to this application. These compactors generally comprise a mechanical arm at the end of which is placed a roller for compacting waste. The mechanical arm allowing the compaction roller to be moved along longitudinal back-and-forth movements within the loading space of the skip. The compacting roller is generally mobile in rotation around 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 dumpster 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 skip 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 carrying out back and forth movements of the compacting roller.

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 control 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 to-and-fro movements of the compacting 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 operating constraints which require the displacement of the skips and/or positioning of the mechanical arm in the longitudinal axis of the skip to operate an optimal compaction of the waste. In addition, the acquisition of a compactor represents a major investment for sorting site operators. This investment is all the more important since operators generally have multi-purpose vehicles such as mechanical shovels.

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
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
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
Comme illustré aux
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
Dans l'exemple illustré aux
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
En complément, l'orientation des dents 42 peut varier comme cela est illustré aux
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
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
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 compacting
Comme cela est illustré aux
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 compacting
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

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
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
Comme cela est illustré aux
Dans l'exemple illustré à la

A l'inverse, dans l'exemple de la
Comme illustré aux
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 can comprise a mechanical arm as an
Dans l'exemple illustré aux
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
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
Il est à noter que dans l'exemple des
Dans l'exemple de la
Dans le cas de la
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 actuator is actuated, it is possible to adjust the orientation of the
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

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

Ce procédé est illustré à la

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
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, when moving the compacting
