  • a jack ejects the compacted material block directly out of the press, where it will be able to be circled.
  • a door is actuated by a cylinder to close the compaction chamber once the compacted block of material has been ejected. Alternatively, the door makes it possible to keep the compressed block thus obstructing the compaction chamber, for the compaction of the next block. Strapping does not take place until the transfer has been completed. It is necessary to wait for the complete retraction of the cylinder to be able to start filling. In addition, the circled block will not be moved until later by the next block of compacted material.

  • JPH04123898 A discloses a compactable material press according to the preamble of claim 1.

Le document US5558014 décrit une presse à matériaux compactables, comprenant une chambre de compactage, dans laquelle le compactage se fait selon un premier axe. Un vérin éjecte le bloc de matériaux compactés directement hors de la presse, où celui-ci va pouvoir être cerclé. Une porte est actionnée par vérin pour fermer la chambre de compactage une fois le bloc de matériaux compactés éjecté. Alternativement, la porte permet de maintenir le bloc compressé obstruant ainsi la chambre de compactage, pour le compactage du bloc suivant. Le cerclage n'a lieu qu'une fois le transfert réalisé. Il faut attendre la rétraction complète du vérin pour pouvoir commencer le remplissage. De plus, le bloc cerclé ne sera déplacé qu'ultérieurement par le bloc de matériaux compactés suivant. Un cycle complet de compactage et liage présente une certaine durée.The document US5558014 describes a press for compactable materials, comprising a compacting chamber, in which the compacting takes place along a first axis. A jack ejects the compacted material block directly out of the press, where it will be able to be circled. A door is actuated by a cylinder to close the compaction chamber once the compacted block of material has been ejected. Alternatively, the door makes it possible to keep the compressed block thus obstructing the compaction chamber, for the compaction of the next block. Strapping does not take place until the transfer has been completed. It is necessary to wait for the complete retraction of the cylinder to be able to start filling. In addition, the circled block will not be moved until later by the next block of compacted material. A complete compaction and binding cycle has a certain duration.

Le document JPH04123898 A décrit une presse à matériaux compactables selon le préambule de la revendication 1.The document JPH04123898 A discloses a compactable material press according to the preamble of claim 1.

Le problème technique que vise à résoudre l'invention est donc de réaliser une presse permettant d'améliorer la durée de compactage, d'éjection et de liage des matériaux compactables.The technical problem which the invention aims to solve is therefore to produce a press making it possible to improve the duration of compaction, ejection and binding of compactable materials.

La demanderesse s'est aperçu que l'inconvénient des systèmes connu est qu'ils restent très séquentiels. Si le cerclage peut avoir lieu en même temps que le compactage du bloc suivant, ce n'est pas le cas de l'éjection. Il s'ensuit que les temps de compactage et de cerclage prennent un temps imposé par la séquence de ces étapes.The Applicant has noticed that the drawback of the known systems is that they remain very sequential. If the strapping can take place at the same time as the compaction of the next block, this is not the case with ejection. It follows that the compaction and strapping times take a time imposed by the sequence of these steps.

A cet effet, un premier objet de l'invention est une presse à matériaux compactables selon la revendication 1.To this end, a first object of the invention is a press for compactable materials according to claim 1.

Ainsi, l'agencement de cette presse permet de découpler le compactage et l'éjection. En particulier, dès que le transfert a été effectué, les moyens de compactage peuvent relâcher la pression, pour permettre le début des opérations en vue du remplissage de la chambre. L'éjection se déroule indépendamment. De même, il est alors possible de placer un dispositif de cerclage à la sortie juste après le deuxième emplacement pour que le liage, notamment par cerclage ou emballage, puisse se faire au fur et à mesure de l'éjection, et ce indépendamment de et parallèlement à la préparation du nouveau bloc de matériaux compactés. Cette presse permet donc de rendre indépendante certaines étapes et d'exercer certaines en parallèles. On gagne donc du temps par rapport à l'art antérieur.Thus, the arrangement of this press makes it possible to decouple the compaction and the ejection. In particular, as soon as the transfer has been carried out, the compacting means can release the pressure, to allow the start of operations with a view to filling the chamber. Ejection takes place independently. Likewise, it is then possible to place a strapping device at the exit just after the second location so that the binding, in particular by strapping or packaging, can be done as the ejection progresses, and this independently of and in parallel with the preparation of the new block of compacted materials. This press therefore makes it possible to make certain stages independent and to exercise some in parallel. Time is therefore saved compared to the prior art.

Selon une réalisation de l'invention, l'axe d'éjection est également transversal à l'axe de compactage. Cela permet de dégager davantage les moyens de transfert, facilitant ainsi leur accès pour la maintenance. Cela évite également d'aligner successivement la ligne de compactage et la ligne d'éjection et de cerclage, diminuant ainsi l'encombrement lorsque la presse est associée à un dispositif de liage. Par exemple l'axe de compactage, l'axe de transfert et l'axe d'éjection peuvent être orthogonaux entre eux.According to one embodiment of the invention, the ejection axis is also transverse to the compaction axis. This makes it possible to free up the transfer means more, thus facilitating their access for maintenance. This also avoids successively aligning the compaction line and the ejection and strapping line, thus reducing the bulk when the press is associated with a binding device. For example the compaction axis, the transfer axis and the ejection axis can be mutually orthogonal.

Selon une réalisation de l'invention, l'axe de transfert est vertical, et l'axe de compactage et l'axe d'éjection sont horizontaux. Cela permet de ne pas ajouter les contraintes du poids des éléments de compactage sur la paroi de fond compactage contre laquelle est dirigée la force de compactage.According to one embodiment of the invention, the transfer axis is vertical, and the compaction axis and the ejection axis are horizontal. This makes it possible not to add the stresses of the weight of the compaction elements on the compaction bottom wall against which the compaction force is directed.

Selon une réalisation de l'invention, le premier emplacement et le deuxième emplacement, sont situés à l'intérieur de ladite presse. Cela facilite le maintien compacté du bloc de matériaux compactés, jusqu'à son éjection.According to one embodiment of the invention, the first location and the second location are located inside said press. This makes it easier to keep the compacted block of material compacted, until it is ejected.

Selon une réalisation de l'invention, au moins l'un parmi les moyens de compactage, les moyens de transfert et les moyens d'éjection, comprennent un bloc de poussée destiné à venir au contact des matériaux compactables et/ou compactés, et un piston apte à entrainer le déplacement du bloc de poussée selon l'axe correspondant. Cela permet de générer des poussées efficaces en particulier pour le compactage. C'est de plus une manière simple de générer une poussée selon un axe.According to one embodiment of the invention, at least one of the compacting means, the transfer means and the ejection means comprises a thrust block intended to come into contact with the compactable and / or compacted materials, and a piston capable of causing the displacement of the thrust block along the corresponding axis. This makes it possible to generate effective thrusts especially for compaction. It is also a simple way to generate thrust along an axis.

Selon une réalisation de l'invention, ladite presse comprend deux lignes de pression hydraulique distinctes, et dans laquelle les moyens de compactage et les moyens d'éjection comprennent chacun un piston et un bloc de poussée, appelés respectivement blocs de compactage et bloc d'éjection, le piston entraînant le bloc de compactage et le piston entraînant le bloc d'éjection étant chacun reliés sur une ligne de pression hydraulique distincte. Cela permet d'utiliser les avantages de pistons actionnés hydrauliquement avec les avantages d'un compactage indépendant de l'éjection. Eventuellement, les moyens de transfert peuvent comprendre un bloc de poussée, dit bloc de transfert, et un piston relié sur la même ligne de pression hydraulique que celle qui est reliée au piston entrainant le bloc de compactage. Cela permet de réduire le nombre de lignes hydraulique. Le transfert s'effectue en effet après le compactage. Il n'est donc pas nécessaire d'avoir une ligne de pression hydraulique autonome pour actionner le piston entrainant le bloc de compactage.According to one embodiment of the invention, said press comprises two separate hydraulic pressure lines, and in which the compacting means and the ejection means each comprise a piston and a thrust block, called respectively compacting blocks and the compression block. ejection, the piston driving the compacting block and the piston driving the ejection block each being connected on a separate hydraulic pressure line. This allows the advantages of hydraulically actuated pistons to be utilized with the advantages of ejection independent compaction. Optionally, the transfer means may comprise a thrust block, called a transfer block, and a piston connected to the same hydraulic pressure line as that which is connected to the piston driving the compacting block. This makes it possible to reduce the number of hydraulic lines. The transfer takes place after compaction. It is therefore not necessary to have an independent hydraulic pressure line to actuate the piston driving the compacting block.

Selon une réalisation de l'invention, la presse à matériaux compactables comprend également une paroi de fond de compactage en vis-à-vis du bloc de compactage, lesdits moyens de compactage comprenant un bloc de compactage, par exemple celui visé ci-dessus, et des moyens d'entraînement de ce bloc en déplacement selon l'axe de compactage.According to one embodiment of the invention, the press for compactable materials also comprises a bottom compacting wall facing the compacting block, said compacting means comprising a compacting block, for example that referred to above, and means for driving this block moving along the compacting axis.

La presse peut également comprendre un logement de collecte comprenant une ouverture d'entrée et une ouverture de sortie, ledit logement de collecte étant destiné à être rempli par des matériaux compactables via ladite ouverture d'entrée, la chambre de compactage comprenant un conduit de compactage avec une entrée et une sortie, cette entrée débouchant sur ledit logement de collecte et la sortie débouchant vers ladite paroi de fond de compactage, ledit bloc de compactage et ses moyens d'entrainements étant agencés de manière à ce que le bloc de compactage puisse traverser ledit logement de collecte, entrer dans ledit conduit de compactage et s'y déplacer vers la paroi de fond de compactage, de manière à permettre le compactage de matériaux compactables se trouvant entre le bloc de compactage et ladite paroi de fond de compactage. Ainsi, les matériaux compactables peuvent être amenés directement au droit des moyens de compactage qui d'un même mouvement de poussée peuvent amener les matériaux compactables dans la chambre de compactage et les y compacter. Lorsque les moyens de compactage comprennent un bloc de compactage, tel qu'évoqué précédemment celui-ci peut avantageusement avoir les mêmes dimensions en section selon un plan perpendiculaire à l'axe de compactage, que les dimensions du conduit de compactage selon un plan perpendiculaire à l'axe de compactage, avec toutefois un jeu permettant le glissement du bloc de compactage contre les parois du conduit de compactage.The press may also include a collection housing comprising an inlet opening and an outlet opening, said collection housing being intended to be filled with compactable materials via said inlet opening, the compaction chamber comprising a compaction duct with an inlet and an outlet, this inlet opening onto said collection housing and the outlet opening towards said bottom wall of compaction , said compaction block and its drive means being arranged so that the compaction block can pass through said collection housing, enter said compaction duct and move there towards the bottom wall of compaction, so to allow the compaction of compactable materials located between the compacting block and said compacting bottom wall. Thus, the compactable materials can be brought directly to the right of the compacting means which, with the same pushing movement, can bring the compactable materials into the compacting chamber and compact them there. When the compaction means comprise a compaction block, as mentioned above, this can advantageously have the same dimensions in section along a plane perpendicular to the compaction axis, as the dimensions of the compaction duct along a plane perpendicular to the compacting axis, with however a play allowing the sliding of the compacting block against the walls of the compacting duct.

Selon une réalisation de l'invention, les moyens de transfert comprennent un support et des moyens d'entrainement de ce support du premier emplacement au deuxième emplacement, le support et les moyens de compactages étant agencés pour que lorsque le support est au premier emplacement, les moyens de compactage permettent de placer le bloc de matériaux compactés sur le support. Par exemple, le premier emplacement est au-dessus du deuxième emplacement, le support formant un monte-charge.According to one embodiment of the invention, the transfer means comprise a support and means for driving this support from the first location to the second location, the support and the compacting means being arranged so that when the support is in the first location, the compacting means make it possible to place the block of compacted material on the support. For example, the first location is above the second location, the support forming a freight elevator.

Selon une réalisation de l'invention, le support comprend :

  • ∘ une première paroi formant ledit support,
  • ∘ une deuxième paroi reliée directement à la première paroi et en vis-à-vis des moyens de compactage, le support étant entre la deuxième paroi et les moyens de compactage,
  • ∘ une troisième paroi reliée directement à la deuxième paroi et en vis-à-vis de la première paroi, la deuxième paroi reliant les première et troisième parois, de manière à former une pièce en « U » formant un coffre et définissant une concavité apte à recevoir les matériaux compactés, la deuxième paroi étant environ perpendiculaire à l'axe de compactage ;
cela permet aux moyens de compactage de venir placer facilement le bloc de matériaux compactés sur le support, lorsqu'il est au premier emplacement, de plus cela permet de maintenir le bloc compacté sur trois côtés, notamment dessous dessus et sur un côté face aux moyens de compactage.According to one embodiment of the invention, the support comprises:
  • ∘ a first wall forming said support,
  • ∘ a second wall connected directly to the first wall and facing the compacting means, the support being between the second wall and the compacting means,
  • ∘ a third wall connected directly to the second wall and facing the first wall, the second wall connecting the first and third walls, so as to form a "U" -shaped part forming a box and defining a suitable concavity receiving the compacted materials, the second wall being approximately perpendicular to the compacting axis;
this allows the compacting means to easily come and place the block of compacted material on the support, when it is in the first location, in addition it makes it possible to keep the compacted block on three sides, in particular below above and on one side facing the means compaction.

Selon une réalisation de l'invention, la presse comprend des moyens de guidage entre le premier emplacement et le deuxième emplacement, ces moyens de guidage étant agencés de manière à guider le déplacement du coffre entre ces deux emplacements. Ces moyens de guidage peuvent comprendre une ou des parois de guidage contre lesquelles le coffre est en contact glissant. Notamment, les moyens de guidage peuvent comprendre une paroi de guidage ou un ensemble de parois de guidage, le coffre étant en contact glissant contre la ou les parois de guidage du premier emplacement au deuxième emplacement.According to one embodiment of the invention, the press comprises guide means between the first location and the second location, these guide means being arranged so as to guide the movement of the box between these two locations. These guide means may comprise one or more guide walls against which the box is in sliding contact. In particular, the guide means may comprise a guide wall or a set of guide walls, the box being in sliding contact against the one or more. guide walls from the first location to the second location.

Selon une réalisation de l'invention, la presse comprend un canal de transfert dont les parois forment l'ensemble de parois de guidage ci-dessus, au moins deux parois du canal de transfert opposées et en vis-à-vis étant environ parallèles à l'axe de compactage et à l'axe de transfert, la chambre de compactage débouchant entre ces parois de guidage opposées, et chacune comportant une lumière débouchant sur le deuxième emplacement. La lumière de l'une de ces parois de guidage opposées permet le passage des moyens d'éjection pour déplacer le bloc de matériaux compactés. La lumière d'une deuxième de ces parois opposées est destinée à laisser passer le bloc de matériaux compactés hors du canal de transfert.According to one embodiment of the invention, the press comprises a transfer channel, the walls of which form the set of guide walls above, at least two walls of the transfer channel opposite and facing each other being approximately parallel to each other. the compaction axis and the transfer axis, the compaction chamber opening between these opposite guide walls, and each comprising a slot opening onto the second location. The lumen of one of these opposite guide walls allows passage of the ejection means to move the block of compacted material. The lumen of a second of these opposite walls is intended to allow the block of compacted material to pass out of the transfer channel.

Selon une réalisation de l'invention, ce canal de transfert comprend une ou des parois de fond en vis-à-vis des moyens de compactage, notamment perpendiculaire(s) à l'axe de compactage et parallèle(s) à l'axe de transfert. La deuxième paroi du coffre va ainsi pouvoir glisser contre cette ou ces parois de fond. De plus ces parois de fond peuvent encaisser la charge due à la pression de compactage, lorsque le compactage des matériaux compactables est destiné à s'exercer contre une paroi du coffre.According to one embodiment of the invention, this transfer channel comprises one or more bottom walls facing the compaction means, in particular perpendicular (s) to the compaction axis and parallel (s) to the axis transfer. The second wall of the safe will thus be able to slide against this or these bottom wall or walls. In addition, these bottom walls can withstand the load due to the compaction pressure, when the compaction of the compactable materials is intended to be exerted against a wall of the box.

Selon une réalisation de l'invention, le canal de transfert comprend deux parois de guidage de fond, chacune de ces parois de guidage de fond étant formée par une plaque de tôle fixée à ladite presse, de manière à former un rail, permettant ainsi le guidage pour le coffre, notamment sa dite deuxième paroi.According to one embodiment of the invention, the transfer channel comprises two bottom guide walls, each of these bottom guide walls being formed by a sheet metal plate fixed to said press, so as to form a rail, thus allowing the guide for the trunk, in particular its said second wall.

Notamment, ces rails sont espacés l'une de l'autre, l'espace entre ces rails s'étendant du premier emplacement au deuxième emplacement. Cela permet de laisser un accès pour le nettoyage de la presse notamment au jet d'eau.In particular, these rails are spaced from one another, the space between these rails extending from the first location to the second location. This makes it possible to leave access for cleaning the press, in particular with a water jet.

Les deux rails peuvent être boulonnés à ladite presse, notamment sur les parois de guidage de fond opposées. Cela permet de changer régulièrement ces rails selon leur usure.The two rails can be bolted to said press, in particular on the opposite bottom guide walls. This makes it possible to regularly change these rails according to their wear.

Lesdites parois de guidage opposées peuvent être venues de matière et dans l'alignement de parois de la chambre de compactage, la ou les parois de fond étant fixées à ces parois de guidage opposées. Cela permet une meilleure résistance de la presse lorsque la pression de compactage s'exerce sur le coffre.Said opposite guide walls may be integral and in line with the walls of the compaction chamber, the bottom wall (s) being fixed to these opposite guide walls. This allows better resistance of the baler when the compaction pressure is exerted on the trunk.

Selon une réalisation de l'invention, la presse comprend un cache agencé en vis-à-vis des rails de manière à couvrir l'espace entre les rails et l'accessibilité au coffre. Dans le cas où la presse est destinée à compacter des ordures ménagères, ce cache va permettre de stopper les projections de liquide et leur permettre de s'écouler vers le bas. Lorsque l'axe de transfert est vertical, la presse peut également comprendre un bac de récupération des liquides, placé sous le deuxième emplacement. Le cache peut par exemple être agencé pour qu'un liquide s'écoulant contre sa paroi aille dans ce bac.According to one embodiment of the invention, the press comprises a cover arranged vis-à-vis the rails so as to cover the space between the rails and access to the safe. In the event that the press is intended to compact household waste, this cover will make it possible to stop the projections of liquid and allow them to flow downwards. When the transfer axis is vertical, the press can also include a liquid collection tank, placed under the second location. The cover can for example be arranged so that a liquid flowing against its wall goes into this tank.

Selon l'invention le coffre précédemment évoqué comprend:

  • deux parties, une partie inférieure formée par ladite cavité, une partie supérieure au-dessus de la troisième paroi du coffre,
  • une quatrième paroi située en partie supérieure, liée à la troisième paroi et s'étendant depuis un bord de la troisième paroi au niveau de l'entrée de la concavité transversalement à l'axe de compactage,
le coffre étant agencé de manière à ce que lorsque le support est placé au deuxième emplacement, ladite quatrième paroi est en vis-à-vis des moyens de compactage de manière à ce que les moyens de compactage puissent compacter les matériaux compactables contre cette quatrième paroi ;
cela permet un compactage d'un bloc de matériaux compactables contre la quatrième paroi du coffre lorsque le support est au niveau du deuxième emplacement ; pendant l'éjection du bloc de matériaux compactés précédemment. On peut ainsi fermer la chambre de compactage sans mécanisme de mouvement supplémentaire, puisque c'est le coffre qui ferme la chambre de compactage lors du transfert de l'un des blocs. De plus le bloc est compacté juste à côté du premier emplacement et de ce fait une fois compacté, il a peu de distance à parcourir pour être transféré dans le coffre.According to the invention, the previously mentioned box comprises:
  • two parts, a lower part formed by said cavity, an upper part above the third wall of the safe,
  • a fourth wall located in the upper part, linked to the third wall and extending from an edge of the third wall at the level of the entrance to the concavity transversely to the compacting axis,
the box being arranged so that when the support is placed in the second location, said fourth wall is opposite the compacting means so that the compacting means can compact the compactable materials against this fourth wall ;
this allows a compacting of a block of compactable material against the fourth wall of the trunk when the support is at the level of the second location; during the ejection of the previously compacted block of material. It is thus possible to close the compaction chamber without an additional movement mechanism, since it is the box which closes the compaction chamber during the transfer of one of the blocks. In addition, the block is compacted right next to the first location and therefore once compacted, it has little distance to travel to be transferred to the trunk.

Selon une réalisation de l'invention, les moyens de compactage sont agencés pour pouvoir exercer une pression jusqu'à l'entrée de la concavité en « U » du coffre. Cela permet d'exercer également la pression de compactage dans le coffre, qui peut alors servir de fond et d'extension de la chambre de compactage. Par exemple, dans le cas d'une réalisation avec la quatrième paroi évoquée précédemment, la presse permet aux moyens de compactage de réaliser un pré-compactage contre la quatrième paroi, puis lorsque la concavité revient au niveau du premier emplacement, pousser le bloc de matériaux compactés dans le coffre, puis exercer un compactage supplémentaire dans le coffre.According to one embodiment of the invention, the compacting means are arranged to be able to exert pressure up to the entry of the “U” -shaped concavity of the trunk. This also allows the compaction pressure to be exerted in the trunk, which can then serve as a bottom and extension of the compaction chamber. For example, in the case of an embodiment with the fourth wall mentioned above, the press allows the compacting means to perform a pre-compacting against the fourth wall, then when the concavity returns to the level of the first location, push the block of compacted material in the trunk, then exert additional compaction in the trunk.

Selon une réalisation de l'invention, le coffre comprend des nervures de renfort à l'extérieur de la concavité, lesdites nervures reliant les parois du coffre ou certaines de ces nervures entre elles et étant agencées en direction de la ou des parois de guidage de fond, notamment les rails cités précédemment, de manière à ce que la charge résultant d'une poussée selon l'axe de compactage soit transférée sur la ou les parois de guidage de fond, notamment sur les rails.According to one embodiment of the invention, the box comprises reinforcing ribs outside the concavity, said ribs connecting the walls of the box or some of these ribs to each other and being arranged in the direction of the guide wall (s) of bottom, in particular the rails mentioned above, so that the load resulting from a thrust along the compaction axis is transferred to the bottom guide wall (s), in particular to the rails.

Selon une réalisation de l'invention, parmi les nervures de renfort il y a :

  • des premières nervures de renfort, qui sont planes et s'étendent depuis les parois du coffre dans des plans parallèles à l'axe de compactage,
  • des deuxièmes nervures de renfort, qui sont planes et joignent entre elles certaines des premières nervures, les deuxièmes nervures étant perpendiculaires aux premières nervures ;
cela permet de renforcer à la fois la solidité du coffre et le report de charge contre les parois de guidage fond.According to one embodiment of the invention, among the reinforcing ribs there are:
  • first reinforcing ribs, which are flat and extend from the walls of the box in planes parallel to the axis of compaction,
  • second reinforcing ribs, which are flat and join together some of the first ribs, the second ribs being perpendicular to the first ribs;
this makes it possible to reinforce both the solidity of the box and the load transfer against the bottom guide walls.

Selon une réalisation de l'invention les deuxièmes nervures sont également reliées aux parois du coffre, notamment la quatrième et la deuxième parois.According to one embodiment of the invention, the second ribs are also connected to the walls of the box, in particular the fourth and the second walls.

Selon une réalisation de l'invention, les premières nervures sont verticales et les deuxièmes nervures sont des pans inclinés vers le bas, en partant depuis leur jonction au coffre. Cela permet un écoulement plus facile de liquide lorsque le coffre est nettoyé au jet.According to one embodiment of the invention, the first ribs are vertical and the second ribs are downwardly inclined faces, starting from their junction to the trunk. This allows for easier flow of liquid when the trunk is hosed down.

Un autre objet de l'invention est une unité de confection de blocs de matériaux compactés et liés, comprenant une presse selon l'invention et un dispositif de liage de blocs de matériaux compactés, ledit dispositif de liage présentant un emplacement de liage positionné à côté du deuxième emplacement et aligné avec l'axe d'éjection, le dispositif de liage étant apte à lier un bloc positionné sur l'emplacement de liage, ledit moyen d'éjection étant agencé pour déplacer le bloc de matériaux compactés dans l'emplacement de liage lorsqu'il l'éjecte hors dudit deuxième emplacement.Another object of the invention is a unit for making blocks of compacted and bonded materials, comprising a press according to the invention and a device for binding blocks of compacted material, said binding device having a binding location positioned next to the second location and aligned with the ejection axis, the binding device being adapted to bind a block positioned on the location of binding, said ejecting means being arranged to move the block of compacted material into the binding location as it ejects it from said second location.

La figure 1 illustre une unité de confection de blocs de matériaux compactés et liés selon l'invention, comprenant une presse à matériaux compactables P selon l'invention, associée à un dispositif de liage R de blocs de matériaux compactés.The figure 1 illustrates a unit for making blocks of compacted and bonded materials according to the invention, comprising a press for compactable materials P according to the invention, associated with a device R for binding compacted blocks of materials.

La presse P comprend une chambre de compactage 16, formée par un conduit de compactage 15, horizontal dans l'exemple illustré. Ce conduit débute par une entrée 19 et se termine par une sortie 18, débouchant sur un emplacement E1, à l'intérieur de la presse P.The press P comprises a compacting chamber 16, formed by a compacting duct 15, horizontal in the example illustrated. This duct begins with an inlet 19 and ends with an outlet 18, leading to a location E 1 , inside the press P.

Dans la présente demande, on emploiera les termes « amont » et «aval» par rapport au sens de déplacement des matériaux compactables et/ou compactés dans la presse.In the present application, the terms “upstream” and “downstream” will be used with respect to the direction of movement of the materials which can be compacted and / or compacted in the press.

En amont, du conduit de compactage 15, la presse P comprend un logement de collecte 6, dont les parois sont alignées et dans le prolongement de celles du conduit de compactage 15. Dans cet exemple, il est rehaussé en hauteur par une hausse 4. Au sommet de cette dernière est l'ouverture de remplissage 5 du logement de collecte 6, par où les matériaux compactables seront versés. Ce logement de collecte 6 présente en amont une ouverture, fermée sur cette figure 1 par un bloc de compactage 14. L'entrée 19 du conduit de compactage 15 débouche dans le logement de collecte 6.Upstream of the compaction duct 15, the press P comprises a collection housing 6, the walls of which are aligned and in the extension of those of the compaction duct 15. In this example, it is raised in height by a rise 4. At the top of the latter is the filling opening 5 of the collection housing 6, through which the compactable materials will be poured. This collection housing 6 has an opening upstream, closed on this figure 1 by a compacting block 14. The inlet 19 of the compacting duct 15 opens into the collection housing 6.

La presse P comprend également des moyens de compactage. Ces derniers comprennent un bloc de poussée, ci-après bloc de compactage 14, actionné par un moyen d'entraînement, formé par un vérin 10. Ce dernier s'étend longitudinalement selon un axe de compactage 1, aligné avec le logement de collecte 6 et le conduit de compactage 15. Le vérin 10 est apte à déplacer longitudinalement le bloc de compactage au travers du logement de collecte 6, à lui faire traverser le conduit de compactage 15, donc la chambre de compactage 16, jusqu'à la sortie 18 du conduit de compactage 15, donc jusqu'à l'emplacement E1.The press P also includes compacting means. The latter comprise a thrust block, hereinafter compaction block 14, actuated by a drive means, formed by a jack 10. The latter extends longitudinally along a compaction axis 1, aligned with the collection housing 6. and the compaction duct 15. The jack 10 is able to move the compaction block longitudinally through the collection housing 6, to make it pass through the compaction duct 15, therefore the compaction chamber 16, up to the outlet 18. from the compaction duct 15, therefore up to location E 1 .

Ainsi, les moyens de compactage 10, 14, sont aptes à pousser les matériaux compactables versés dans l'espace de collecte 6, à l'intérieur de la chambre de compactage 16, puis à exercer une pression de compactage, dans cette chambre de compactage 16 selon un axe de compactage 1. Ainsi, ils pourront compacter ces matériaux compactables en un bloc de matériaux compactés et positionner ce bloc de matériaux compactés en un premier emplacement E1, toujours selon un axe 1.Thus, the compacting means 10, 14 are able to push the compactable materials poured into the collection space 6, inside the compacting chamber 16, then to exert a compacting pressure, in this compacting chamber. 16 along a compaction axis 1. Thus, they will be able to compact these compactable materials into a block of compacted materials and position this block of compacted materials in a first location E 1 , still along an axis 1.

Sur la figure 1, est représenté un coffre 40 en position amont. Il comprend une première paroi, ici horizontale, formant un support. Sur la figure 1, le support est au niveau de l'emplacement E1. Cette première paroi 41 est destinée à recevoir le bloc de matériaux compactés, qui aura été poussé par le bloc de compactage 14 jusqu'à l'emplacement E1.On the figure 1 , is shown a box 40 in the upstream position. It comprises a first wall, here horizontal, forming a support. On the figure 1 , the support is at location E 1 . This first wall 41 is intended to receive the block of compacted materials, which will have been pushed by the compacting block 14 to location E 1 .

Ce coffre 40 est relié à un moyen d'entraînement, un vérin de transfert 20 dans cet exemple. Ce vérin de transfert 20 s'étend longitudinalement selon un axe de transfert 2, vertical dans l'exemple illustré.This box 40 is connected to a drive means, a transfer cylinder 20 in this example. This transfer cylinder 20 extends longitudinally along a transfer axis 2, vertical in the example illustrated.

D'une manière générale selon l'invention, l'axe de compactage 1 et l'axe de transfert 2 sont distincts et par exemple sécants. Ils sont également transversaux l'un par rapport à l'autre, notamment perpendiculaires dans cet exemple.In general according to the invention, the compaction axis 1 and the transfer axis 2 are distinct and for example intersecting. They are also transverse to each other, in particular perpendicular in this example.

Ainsi, ce vérin 20 de transfert et le coffre 40 forment des moyens de transfert, agencés pour être aptes à entrainer le déplacement du bloc de matériaux compactés selon l'axe de transfert 2, du premier emplacement E1 vers un deuxième emplacement, non visible en figure 1 mais situé à un étage inférieur dans cet exemple. Le coffre 40 forme ainsi un bloc de poussée. Il forme également un monte-charge dans cet exemple où l'axe de transfert 2 est vertical, le coffre 40 étant destiné à descendre le bloc de matériaux compactés.Thus, this transfer jack 20 and the box 40 form transfer means, arranged to be able to cause the movement of the compacted material block along the transfer axis 2, from the first location E 1 to a second location, not visible. in figure 1 but located on a lower floor in this example. The trunk 40 thus forms a thrust block. It also forms a freight elevator in this example where the transfer axis 2 is vertical, the box 40 being intended to lower the block of compacted material.

Le deuxième emplacement est situé juste en amont d'une sortie finale 36 de la presse P, sous l'emplacement E1 dans cette illustration. Le deuxième emplacement est entre cette sortie finale 36 et un bloc de poussée, dit bloc d'éjection (non visible sur la figure 1), apte à être entrainé en déplacement par un vérin d'éjection 30. Ce dernier et la sortie finale 36 sont alignés selon un axe de d'éjection 3, selon lequel le vérin d'éjection est apte à déplacer le bloc d'éjection.The second location is located just upstream of a final outlet 36 of the press P, below location E 1 in this illustration. The second location is between this final outlet 36 and a thrust block, called the ejection block (not visible on the figure 1 ), able to be driven in movement by an ejection cylinder 30. The latter and the final outlet 36 are aligned along an ejection axis 3, according to which the ejection cylinder is able to move the ejection block .

De ce fait, le vérin 30 en entrainant le bloc d'éjection est apte à éjecter un bloc compacté qui serait positionné sur l'emplacement E2.As a result, the jack 30 by driving the ejection block is able to eject a compacted block which would be positioned on the location E 2 .

D'une manière générale selon l'invention, l'axe d'éjection 3 est distinct de l'axe de compactage 1 et de l'axe de transfert 2. Il est également transversal par rapport à l'axe de transfert 2 et notamment sécant à ce dernier.Generally according to the invention, the ejection axis 3 is distinct from the compaction axis 1 and from the transfer axis 2. It is also transverse to the transfer axis 2 and in particular secant to the latter.

Dans cet exemple où les axes de compactage 1 et d'éjection 3 sont horizontaux et l'axe de transfert 2 est vertical, cela permet d'avoir un compactage à un étage supérieur et une éjection à un étage inférieur.In this example where the compacting 1 and ejection 3 axes are horizontal and the transfer axis 2 is vertical, this makes it possible to have compaction at an upper stage and ejection at a lower stage.

Le coffre 40 présente également une deuxième paroi 42 de coffre, en vis-à-vis de la sortie 18 et du bloc de compactage 14, lorsque le coffre 14 est en position amont, comme en figure 1. La première paroi 41 de coffre étant à l'emplacement E1, elle se situe entre la sortie 18 du conduit de compactage 15 et cette deuxième paroi 42 de coffre. Le coffre forme ainsi une cavité prolongeant la chambre de compactage 16. Le bloc de compactage 14 est apte à venir compacter les matériaux compactables contre cette deuxième paroi 42 de coffre, comme il sera expliqué ci-après.The box 40 also has a second wall 42 of the box, facing the outlet 18 and the compaction block 14, when the box 14 is in the upstream position, as in figure 1 . The first trunk wall 41 being at the location E 1 , it is located between the outlet 18 of the compacting duct 15 and this second trunk wall 42. The trunk thus forms a cavity extending the compaction chamber 16. The compaction block 14 is able to compact the compactable materials against this second wall 42 of the trunk, as will be explained below.

Comme illustré en figure 2, la presse P comprend une partie principale 7 formant un bloc compact, comprenant le conduit de compactage 15, dont on peut voir l'ouverture 18, le logement de collecte 6 et, en arrière de celui-ci sur cette figure, un prolongement pour porter le vérin 10. Cette réalisation en bloc, et notamment de nombreuses entretoises et nervures de renfort, forment une structure particulièrement résistante dans le sens d'une pression selon l'axe de compactage 1.As shown in figure 2 , the press P comprises a main part 7 forming a compact block, comprising the compaction duct 15, the opening 18 of which can be seen, the collection housing 6 and, behind the latter in this figure, an extension for support the jack 10. This block embodiment, and in particular numerous spacers and reinforcing ribs, form a particularly strong structure in the direction of pressure along the compacting axis 1.

L'extérieur de la chambre de compactage 16 est référencé 17 sur cette figure 2.The exterior of the compaction chamber 16 is referenced 17 on this figure 2 .

La sortie 18 du conduit de compactage 15 débouche dans un canal de transfert 26, s'étendant selon l'axe de transfert 2, soit verticalement dans cet exemple, et du premier emplacement E1 au deuxième emplacement E2. Ce couloir 26 comprend des parois de guidage 27 et 28 latérales, de part et d'autre de la sortie 18. Elles sont destinées à guider le coffre 40 lors de son transfert entre ces deux emplacements E1 et E2. La paroi de guidage latérale 27 à droite sur cette figure comprend à l'étage inférieur une lumière 33, destinée à laisser passer le vérin d'éjection 30. L'autre paroi de guidage latérale 28, comprend à l'étage inférieur également, la sortie finale 36 de la presse P.The outlet 18 of the compacting duct 15 opens into a transfer channel 26, extending along the transfer axis 2, ie vertically in this example, and from the first location E 1 to the second location E 2 . This corridor 26 comprises lateral guide walls 27 and 28, on either side of the outlet 18. They are intended to guide the box 40 during its transfer between these two locations E 1 and E 2 . The lateral guide wall 27 on the right in this figure comprises at the lower level a slot 33, intended to allow the ejection cylinder 30 to pass. The other lateral guide wall 28, also comprises at the lower level also, the final output 36 of the press P.

En partie supérieure du canal de transfert 26, une poutrelle 23 relie les parois de guidage 27 et 28. Outre le renfort mécanique de ces parois de guidage 27 et 28, la poutrelle sert à positionner le vérin de transfert 20, au travers d'un trou 25.In the upper part of the transfer channel 26, a beam 23 connects the guide walls 27 and 28. In addition to the mechanical reinforcement of these guide walls 27 and 28, the beam is used to position the transfer cylinder 20, through a hole 25.

En avant sur cette figure, on peut observer des plaques de tôles qui forment des plaques de fixation 29, destinées à recevoir des rails de guidage.Forward in this figure, one can observe the metal plates which form fixing plates 29, intended to receive guide rails.

Les figures 3 et 4 illustrent le coffre 40. Il comprend une partie inférieure formée par la première paroi 41 de coffre, la deuxième paroi 42 de coffre et une troisième paroi 43 de coffre. Ces trois parois forment une portion en « U » du coffre, dont les première et troisième parois de coffre forment les branches. Ainsi, ces trois parois forment une concavité apte à recevoir un bloc de matériaux compactés.The figures 3 and 4 illustrate the box 40. It comprises a lower part formed by the first wall 41 of the box, the second wall 42 of the box and a third wall 43 of the box. These three walls form a “U” -shaped portion of the box, of which the first and third box walls form the branches. Thus, these three walls form a concavity capable of receiving a block of compacted material.

La concavité est fermée sur les côtés par les parois de guidage 27 et 28, lorsque le coffre 40 est en position amont.The concavity is closed on the sides by the guide walls 27 and 28, when the box 40 is in the upstream position.

Selon une réalisation de l'invention, les dimensions de cette cavité dans un plan perpendiculaire à l'axe de compactage 1 correspondent environ à celle de la sortie 18 du conduit de compactage 15.According to one embodiment of the invention, the dimensions of this cavity in a plane perpendicular to the compaction axis 1 correspond approximately to that of the outlet 18 of the compaction duct 15.

Des cinquième 45a et sixième 45b parois de ce coffre 40 forment ses parois latérales qui seront aptes à glisser contre les parois de guidage, respectivement 27 et 28.Fifth 45a and sixth 45b walls of this box 40 form its side walls which will be able to slide against the guide walls, respectively 27 and 28.

Selon une réalisation de l'invention, le coffre 40 comprend une quatrième paroi 44 de coffre, s'étendant depuis le bord de la troisième paroi 43 de coffre définissant l'extrémité libre de la branche de la portion en « U », soit à l'embouchure de la concavité. Dans cet exemple, elle s'étend vers le haut et perpendiculairement à la troisième paroi 43 de coffre.According to one embodiment of the invention, the box 40 comprises a fourth box wall 44, extending from the edge of the third box wall 43 defining the free end of the branch of the “U” -shaped portion, ie at the mouth of the concavity. In this example, it extends upwards and perpendicularly to the third wall 43 of the trunk.

Comme on peut le voir en figure 4, cette quatrième paroi 44 de coffre et l'espace à l'arrière de celle-ci forme une partie supérieure du coffre 40, et présente un logement 46 pour loger le vérin de transfert 20.As can be seen in figure 4 , this fourth trunk wall 44 and the space at the rear thereof forms an upper part of the trunk 40, and has a housing 46 for accommodating the transfer cylinder 20.

Les figures 5 et 6 illustrent la partie principale 7 et le coffre 40 assemblés, ce dernier étant logé à l'intérieur du canal de transfert 26. Le coffre 40 y est représenté en position aval, soit à l'étage inférieur dans l'exemple illustré.The figures 5 and 6 illustrate the main part 7 and the box 40 assembled, the latter being housed inside the transfer channel 26. The box 40 is shown there in the downstream position, ie on the lower floor in the example illustrated.

Selon une réalisation de l'invention, par exemple comme dans l'exemple illustré, le vérin de transfert 20 est situé au-dessus du coffre 40. En figures 5 et 6, il est donc déployé, le piston de transfert 22 qu'il comprend est sorti du corps de piston 21 de ce vérin de transfert, pour amener la concavité du coffre 40 au deuxième emplacement E2. Le piston de transfert 22 est apte à être rétracté, pour amener la concavité du coffre 40 au premier emplacement E1.According to one embodiment of the invention, for example as in the example illustrated, the transfer cylinder 20 is located above the box 40. In figures 5 and 6 , it is therefore deployed, the transfer piston 22 that it comprises is released from the piston body 21 of this transfer cylinder, to bring the concavity of the box 40 to the second location E 2 . The transfer piston 22 is able to be retracted, to bring the concavity of the box 40 to the first location E 1 .

Selon une variante non représentée, le vérin peut se placer dessous le coffre. Dans ce cas, il fonctionne de manière inverse, à savoir qu'il se déploie pour amener la concavité du coffre au premier emplacement E1 et se repli pour l'amener au deuxième emplacement E2.According to a variant not shown, the jack can be placed under the trunk. In this case, it works in the opposite way, namely that it deploys to bring the concavity of the trunk to the first location E 1 and folds back to bring it to the second location E 2 .

La réalisation avec le vérin de transfert 20 situé au-dessus du coffre, présente néanmoins l'avantage de laisser un espace libre sous l'emplacement E2, ce qui permet plus facilement d'y agencer un bac récupérateur 66 (visible notamment en figure 1), apte à collecter les jus s'écoulant du bloc de matériaux compactés. Cela est particulièrement intéressant lors du compactage d'ordures ménagères.The realization with the transfer cylinder 20 located above the trunk, nevertheless has the advantage of leaving a free space under the location E 2 , which makes it easier to fit a collecting tank 66 there (visible in particular by figure 1 ), capable of collecting the juices flowing from the block of compacted materials. This is particularly useful when compacting household waste.

Comme illustré en figure 6, lorsque le coffre 40 est amené au deuxième emplacement E2, la partie supérieure du coffre 40 est au niveau de l'emplacement E1. Ainsi, la quatrième paroi 44 de coffre ferme la sortie 18 du conduit de compactage 15. Elle définit alors une paroi de fond de la chambre de compactage 16, contre laquelle les moyens de compactage 10, 14, vont pouvoir compresser les matériaux compactables.As shown in figure 6 , when the box 40 is brought to the second location E 2 , the upper part of the box 40 is at the level of the location E 1 . Thus, the fourth trunk wall 44 closes the outlet 18 of the compaction duct 15. It then defines a bottom wall of the compaction chamber 16, against which the compaction means 10, 14 will be able to compress the compactable materials.

Selon une réalisation de l'invention, et tel qu'illustré dans ces figures, l'axe de compactage 1 est horizontal. Cela permet que seule la force générée par les moyens de compactage, dans cet exemple par le vérin de compactage 10 via le bloc de compactage 14, soit transférée au coffre 40. Le poids des moyens de compactage 10, 14, ne se reporte pas sur cette quatrième paroi 44 de coffre. Cela facilite la réalisation du coffre 40 dans laquelle cette quatrième paroi 44 de coffre forme la paroi contre laquelle les matériaux sont compactés.According to one embodiment of the invention, and as illustrated in these figures, the compacting axis 1 is horizontal. This allows only the force generated by the compacting means, in this example by the compacting jack 10 via the compacting block 14, to be transferred to the box 40. The weight of the compacting means 10, 14, does not refer to this fourth wall 44 of the trunk. This facilitates the production of the box 40 in which this fourth trunk wall 44 forms the wall against which the materials are compacted.

Le canal de transfert 26 comprend deux parois de fond, formant deux rails 13, fixés sur la partie principale 7 de la presse P, notamment à l'extrémité des parois de guidage 27 et 28, en particulier sur les plaques de fixation 29.The transfer channel 26 comprises two bottom walls, forming two rails 13, fixed on the main part 7 of the press P, in particular at the end of the guide walls 27 and 28, in particular on the fixing plates 29.

Ces rails 13 sont par exemple des plaques de tôles boulonnées sur les plaques de fixation 29. Ils dépassent en partie vers l'axe de transfert 2. Ces parties de ces rails 13 vont former deux parois de guidage du coffre 40, contre lesquelles vont glisser des patins 48 du coffre 40. Ces derniers forment un prolongement de la deuxième paroi 42 de coffre, à l'arrière et à l'extérieur du coffre 40. Ils s'étendent également dans la partie supérieure du coffre, et sont reliés à la quatrième paroi 44 du coffre via les parois latérales 45a et 45b. Il y a donc un contact entre les patins 48 et les rails 13 sur toute la hauteur du coffre, ce qui améliore le guidage.These rails 13 are for example sheet metal plates bolted to the fixing plates 29. They partially protrude towards the transfer axis 2. These parts of these rails 13 will form two guide walls of the box 40, against which will slide. runners 48 of the safe 40. The latter form an extension of the second wall 42 of the safe, at the rear and outside of the safe 40. They also extend into the upper part of the safe, and are connected to the fourth wall 44 of the trunk via the side walls 45a and 45b. There is therefore contact between the pads 48 and the rails 13 over the entire height of the boot, which improves guidance.

Le coffre va également reporter la charge résultant de la force de compactage F sur les rails 13 via ces patins 48.The box will also transfer the load resulting from the compaction force F on the rails 13 via these pads 48.

Pour permettre d'appliquer davantage de force de compactage F, les rails 13 sont plans ainsi que les plaques de fixation 29. On peut par exemple boulonner les rails 13 sur ces plaques de fixation 29. Outre une bonne tenue mécanique, ces boulons peuvent être enlevés, soit pour changer les rails 13, soit pour changer les patins 48, qui peuvent par exemple être formés de poutrelles, verticales dans cet exemple.To make it possible to apply more of the compaction force F, the rails 13 are plane as well as the fixing plates 29. One can for example bolt the rails 13 on these fixing plates 29. In addition to a good mechanical strength, these bolts can be removed, either to change the rails 13, or to change the pads 48, which can for example be formed of beams, vertical in this example.

Les rails 13 et les plaques de fixation 29 peuvent être perpendiculaires à l'axe de compactage 1. Leur fixation mutuelle pourra ainsi encaisser des forces de compactage F supérieures.The rails 13 and the fixing plates 29 can be perpendicular to the compaction axis 1. Their mutual fixing will thus be able to withstand higher compaction forces F.

Pour pouvoir transférer la charge résultant du compactage plus efficacement sur ces rails 13. La surface de glissement de ces patins 48 peut également être plane et perpendiculaire à l'axe de compactage 1.In order to be able to transfer the load resulting from the compaction more efficiently on these rails 13. The sliding surface of these pads 48 can also be flat and perpendicular to the compaction axis 1.

Selon une réalisation de l'invention, pour améliorer le transfert de charge contre les rails 13, lors du compactage des matériaux contre la quatrième paroi 44 de coffre ou la deuxième paroi 42 de coffre, le coffre 40 comprend des nervures de renfort.According to one embodiment of the invention, to improve the transfer of load against the rails 13, during the compaction of materials against the fourth wall 44 of the box or the second wall 42 of the box, the box 40 comprises reinforcing ribs.

Ces nervures de renfort s'étendent vers l'arrière du coffre 40, notamment depuis l'arrière de la deuxième 42 ou de la quatrième paroi 44 de coffre :

  • des nervures verticales 50, 51, à l'arrière de la deuxième paroi 42 de coffre,
  • des nervures verticales 53, 55a à l'arrière de la quatrième paroi 44 de coffre,
  • des nervures transversales 52, 54, fixées aux et entre les nervures verticales.
These reinforcing ribs extend towards the rear of the box 40, in particular from the rear of the second 42 or of the fourth wall 44 of the box:
  • vertical ribs 50, 51, at the rear of the second trunk wall 42,
  • vertical ribs 53, 55a at the rear of the fourth wall 44 of the trunk,
  • transverse ribs 52, 54, attached to and between the vertical ribs.

Il peut y avoir également des nervures perpendiculaires 56 à l'axe de compactage 1, certaines 53 des nervures précédentes se reportant sur ces nervures perpendiculaires 56.There may also be ribs 56 perpendicular to the compaction axis 1, some 53 of the previous ribs being referred to these perpendicular ribs 56.

L'exemple illustré comprend l'ensemble de ces nervures.The illustrated example includes all of these ribs.

Selon une réalisation de l'invention, le coffre 40 comprend notamment des nervures en « L » parallèles à l'axe de compactage 1 et à l'axe de transfert 2. Les branches du « L » sont fixées dessous la première paroi 41 de coffre 40 et derrière la deuxième paroi de coffre 40. Cela renforce la résistance du coffre, améliorant ainsi la possibilité de réaliser le compactage également contre la deuxième paroi 42 de coffre 40.According to one embodiment of the invention, the box 40 comprises in particular "L" shaped ribs parallel to the compaction axis 1 and to the transfer axis 2. The branches of the "L" are fixed below the first wall 41 of trunk 40 and behind the second trunk wall 40. This increases the resistance of the trunk, improving thus the possibility of carrying out the compaction also against the second wall 42 of the box 40.

Notamment, il y a deux nervures en « L » latérales 50 de part et d'autre d'une nervure en « L » centrale 51. Des nervures transversales 52, notamment perpendiculaires aux nervures en « L », joignent les nervures en « L » latérales 50 à la nervure en « L » centrale « L » 51.In particular, there are two lateral "L" ribs 50 on either side of a central "L" rib 51. Transverse ribs 52, in particular perpendicular to the "L" ribs, join the "L" ribs. Side 50 to the central “L” rib 51.

Une nervure intermédiaire 56 perpendiculaire à l'axe de compactage 1 est formée par une portion supérieure d'une plaque dont la portion inférieure forme la deuxième paroi 42 de coffre.An intermediate rib 56 perpendicular to the compaction axis 1 is formed by an upper portion of a plate, the lower portion of which forms the second wall 42 of the trunk.

Dans cet exemple, les nervures en « L » latérales 50 se prolongent le long et fixées à cette nervure intermédiaire 56. Des équerres 57 s'étendant horizontalement peuvent renforcer les liaisons entre celles-ci.In this example, the lateral "L" ribs 50 extend along and are fixed to this intermediate rib 56. Brackets 57 extending horizontally can reinforce the links between them.

Le report de charge depuis la quatrième paroi 44 de coffre se fait notamment via les parois latérales 45a et 45b de coffre 40, fixées à cette quatrième paroi 44 et aux patins 48.The load transfer from the fourth wall 44 of the box is done in particular via the side walls 45a and 45b of the box 40, fixed to this fourth wall 44 and to the pads 48.

Il est également possible, comme illustré sur ces figures de relier la quatrième paroi 44 de coffre à ladite nervure intermédiaire 56 via des nervures verticales 53, 55a. Ces dernières peuvent également ou alternativement être reliées à la face externe, à savoir celle à l'extérieur de la concavité, de la troisième paroi 43 de coffre. On renforce ainsi la résistance de la quatrième paroi 44 de coffre à la force de compactage F. Des nervures transversales 54, notamment perpendiculaires aux nervures verticales 53, 55a, peuvent joindre celles-ci entre elles.It is also possible, as illustrated in these figures, to connect the fourth trunk wall 44 to said intermediate rib 56 via vertical ribs 53, 55a. The latter can also or alternatively be connected to the external face, namely that outside the concavity, of the third wall 43 of the trunk. This reinforces the resistance of the fourth wall 44 of the trunk to the compaction force F. Transverse ribs 54, in particular perpendicular to the vertical ribs 53, 55a, can join them together.

Dans cet exemple, des nervures latérales verticales 53 en forme de cadre joignent directement la quatrième paroi 44 de coffre et la nervure intermédiaire 56. Elles peuvent être de part et d'autres d'une nervure verticale centrale 55a en appui ou fixé au muret cylindrique du logement 46 pour le piston 22 du vérin de transfert 20. Diamétralement opposé par rapport à ce muret, une nervure verticale 55b s'étend jusqu'à la nervure intermédiaire 56, par exemple en étant aligné avec la nervure en « L » centrale 51.In this example, vertical lateral ribs 53 in the form of a frame directly join the fourth chest wall 44 and the intermediate rib 56. They can be on either side of a central vertical rib 55a in support or fixed to the cylindrical wall. of the housing 46 for the piston 22 of the transfer cylinder 20. Diametrically opposed to this wall, a vertical rib 55b extends to the intermediate rib 56, for example by being aligned with the central "L" rib 51 .

A noter qu'en lieu et place des rails 13, on peut utiliser une simple paroi.Note that instead of the rails 13, one can use a single wall.

L'utilisation de rails 13 permet une meilleure gestion des reports de charge.The use of rails 13 allows better management of load transfers.

Ces rails 13 sont espacés et écartés transversalement. Ils laissent ainsi accès au coffre 40, même lorsque la presse P est assemblée. Cela permet de nettoyer l'arrière du coffre au jet d'eau.These rails 13 are spaced and spaced apart transversely. They thus provide access to the trunk 40, even when the press P is assembled. This makes it possible to clean the back of the trunk with a water jet.

Les nervures transversales 52 peuvent être, comme dans l'exemple illustré, orientées vers le bas en partant depuis les parois du coffre 40, pour faciliter l'évacuation de l'eau de nettoyage ou des jus résultant de la compression d'ordures ménagères.The transverse ribs 52 can be, as in the example illustrated, oriented downwards starting from the walls of the box 40, to facilitate the evacuation of the cleaning water or the juices resulting from the compression of household refuse.

Les figures 7 à 13 illustrent la façon dont la presse P permet de compacter les matériaux compactables, notamment des ordures ménagères 0.The figures 7 to 13 illustrate how the press P compacts compactable materials, in particular household waste 0.

En figure 7, les ordures ménagères 0 ont été versées à l'intérieur du logement de collecte 6. Le vérin de compactage 10 est replié, son piston de compactage 12 étant rétracté dans son corps de piston 11. Le coffre est à l'étage supérieur, sa première paroi 41, et donc sa concavité, étant au premier emplacement E1.In figure 7 , the household waste 0 has been poured inside the collection housing 6. The compaction cylinder 10 is folded up, its compaction piston 12 being retracted into its piston body 11. The box is on the upper floor, its first wall 41, and therefore its concavity, being at the first location E 1 .

Selon une étape de compactage initiale, au cours d'une sous-étape, le coffre 40 est descendu à l'étage inférieur par le vérin de transfert 20 en amenant la concavité au deuxième emplacement E2. La quatrième paroi 44 de coffre ferme alors la sortie 18 du conduit de compactage 15, et forme alors une paroi de fond de la chambre de compactage 16.According to an initial compacting step, during a sub-step, the box 40 is lowered to the lower floor by the transfer jack 20, bringing the concavity to the second location E 2 . The fourth trunk wall 44 then closes the outlet 18 of the compaction duct 15, and then forms a bottom wall of the compaction chamber 16.

Selon une sous-étape suivante, le vérin de compactage 10 se déploie selon l'axe de compactage 1 et entraine en déplacement le bloc de compactage 14 au travers du logement de collecte 6, poussant les ordures ménagères à l'intérieur du conduit de compactage 15, et les entrainant au travers de ce conduit jusqu'à la quatrième paroi de coffre 44. Ensuite le vérin exerce une pression de compactage, comprimant et compactant les ordures ménagères 0 contre cette quatrième paroi 44. La force exercée est reportée par les différentes nervures via les patins 48 contre les rails 13. On obtient un premier bloc de matériaux compactés B1, comme on peut le voir en figure 8.According to a following sub-step, the compaction jack 10 is deployed along the compaction axis 1 and drives the compaction block 14 in motion through the collection housing 6, pushing the household waste inside the compaction duct 15, and driving them through this duct to the fourth trunk wall 44. Then the jack exerts a compacting pressure, compressing and compacting the household waste 0 against this fourth wall 44. The force exerted is transferred by the various ribs via the pads 48 against the rails 13. A first block of compacted material B 1 is obtained, as can be seen in figure 8 .

Ensuite, le vérin de transfert 20 se replie et remonte le coffre au premier étage. Comme on peut le voir en figure 9, la concavité du coffre fait à nouveau face à l'ouverture 18 du conduit de compactage 15.Then, the transfer cylinder 20 folds up and raises the trunk to the first floor. As can be seen in figure 9 , the concavity of the trunk again faces the opening 18 of the compaction duct 15.

Le piston de compactage 12 est ensuite déployé davantage hors du corps de piston 11. Dans l'exemple illustré, la course de ce piston 12 est telle que lorsqu'il est déployé complètement, le bloc de compactage 14 s'arrête au niveau de la sortie 18 du conduit de compactage 15. Alternativement ou également, des moyens de commande du vérin de compactage 10 sont aptes à commander la sortie du piston de compactage 12 pour que le bloc de compactage 14 s'arrête au niveau de cette sortie 18. Ainsi, les moyens de compactage 10, 14, permettent également de déplacer le premier bloc de matériaux compactés B1 sur le premier emplacement E1, sur la première paroi 41 de coffre.The compaction piston 12 is then deployed further out of the piston body 11. In the example illustrated, the stroke of this piston 12 is such that when it is fully extended, the compaction block 14 stops at the level of the piston. outlet 18 of the compacting duct 15. Alternatively or also, means for controlling the compacting cylinder 10 are able to control the output of the compacting piston 12 so that the compacting block 14 stops at this output 18. Thus, the compacting means 10, 14 also make it possible to move the first block of compacted material B 1 on the first location E 1 , on the first wall 41 of the trunk.

Eventuellement, ce déplacement du premier bloc de matériaux compactés B1 peut être suivi d'une sous-étape de finalisation du compactage, dans la concavité. Dans ce cas, la concavité sert de prolongement de la chambre de compactage, la deuxième paroi 42 de coffre jouant le rôle de paroi de fond de la chambre de compactage 16.Optionally, this displacement of the first block of compacted material B 1 can be followed by a sub-step for finalizing the compaction, in the concavity. In this case, the concavity serves as an extension of the compaction chamber, the second trunk wall 42 playing the role of the bottom wall of the compaction chamber 16.

Comme on peut le voir en figure 10, le bloc de matériaux compactés B1 est maintenu compacté entre les première 41, deuxième 42, et troisième 43 parois du coffre 40, la concavité formant ainsi une pince de maintien. Il est également maintenu compacté latéralement par les parois de guidage 27 et 28 et en amont par le bloc de compactage 14.As can be seen in figure 10 , the block of compacted material B 1 is kept compacted between the first 41, second 42, and third 43 walls of the box 40, the concavity thus forming a holding clamp. It is also kept compacted laterally by the guide walls 27 and 28 and upstream by the compacting block 14.

Ensuite, a lieu une étape de transfert, au cours de laquelle le vérin de transfert 20 se déploie à nouveau et amène le premier bloc de matériaux compactés B1, au niveau du deuxième emplacement E2, tel qu'illustré en figure 11. On peut voir également que de ce fait la quatrième paroi 44 de coffre obstrue à nouveau la sortie 18 du conduit de compactage 15.Then takes place a transfer step, during which the transfer cylinder 20 is deployed again and brings the first block of compacted material B 1 , at the second location E 2 , as illustrated in figure 11 . It can also be seen that for this reason the fourth wall 44 of the trunk again obstructs the outlet 18 of the compacting duct 15.

Ainsi, comme illustré en figure 11, le premier bloc de matériaux compactés B1 est prêt à être éjecté et les étapes en vue du compactage suivant vont pouvoir commencer.Thus, as illustrated in figure 11 , the first block of compacted material B 1 is ready to be ejected and the steps for the next compacting will be able to begin.

Le vérin d'éjection 30 est donc alors actionné, poussant le bloc d'éjection 34 (visible notamment en figure 10). Ce dernier va pousser progressivement le premier bloc de matériaux compactés B1 selon l'axe d'éjection 3 et hors de la presse P, au travers de la sortie finale 36.The ejection cylinder 30 is therefore actuated, pushing the ejection unit 34 (visible in particular by figure 10 ). The latter will gradually push the first block of compacted material B 1 along the ejection axis 3 and out of the press P, through the final outlet 36.

On peut comme illustré en figure 1, disposer un dispositif de liage R, notamment de cerclage, qui va cercler ou emballer progressivement le premier bloc de matériaux compactés B1 au fur et à mesure de sa sortie.As illustrated in figure 1 , have a binding device R, in particular strapping, which will gradually strap or wrap the first block of compacted material B 1 as it is released.

En parallèle, dès que le vérin d'éjection 30 est actionné, le vérin de compactage 10 est replié pour ramener le bloc de compactage 14 en aval du logement de collecte 6. Alors que l'éjection et éventuellement le liage du premier bloc de matériaux compactés B1 se poursuivent, le logement de collecte est à nouveau rempli par des ordures ménagères 0, comme on peut le voir en figure 12.In parallel, as soon as the ejection cylinder 30 is actuated, the compaction cylinder 10 is folded back to bring the compaction block 14 downstream of the collection housing 6. While the ejection and possibly the binding of the first block of material compacted B 1 continue, the collection housing is again filled with household waste 0, as can be seen in figure 12 .

Ensuite pendant que l'éjection et éventuellement le liage du premier bloc de matériaux compactés B1 se poursuivent, le vérin de compactage se déploie à nouveau et compacte les ordures ménagères 0 dans la chambre de compactage 16 contre la quatrième paroi 44 de coffre.Then while the ejection and possibly the binding of the first block of compacted material B 1 continues, the compaction cylinder deploys again and compacts the household waste 0 in the compaction chamber 16 against the fourth wall 44 of the trunk.

Comme illustré en figure 13, quand l'éjection et éventuellement l'emballage du premier bloc de matériaux compactés B1 est terminée, un deuxième bloc de matériaux compactés B2 est prêt à être transféré au seuil de la sortie 18 du conduit de compactage.As shown in figure 13 , when the ejection and possibly the packaging of the first block of compacted materials B 1 is completed, a second block of compacted materials B 2 is ready to be transferred to the threshold of the outlet 18 of the compacting duct.

La presse P a donc permis le compactage d'un deuxième bloc de matériaux compactés B2 en même temps que l'éjection, et éventuellement le liage, d'un premier bloc de matériaux compactés B1.The press P therefore made it possible to compact a second block of compacted materials B 2 at the same time as the ejection, and possibly the binding, of a first block of compacted materials B 1 .

En figures 14 et 15, le temps de compactage, d'éjection et éventuellement de liage est grandement amélioré.In figures 14 and 15 , the time of compaction, ejection and possibly binding is greatly improved.

En figure 14, on peut voir que selon l'art antérieur, le compactage, l'ouverture de la porte, l'éjection du bloc de matériaux compactés et le cerclage, la fermeture de la porte et un nouveau compactage, se font de manière séquentielle.In figure 14 , it can be seen that according to the prior art, the compaction, the opening of the door, the ejection of the block of compacted material and the strapping, the closing of the door and a new compacting, are carried out sequentially.

En revanche, grâce à la presse selon l'invention, après le compactage initial et le premier transfert, le compactage d'un bloc de matériaux se fait en parallèle de l'éjection et du cerclage du bloc se matériaux compactés précédent. Ainsi, l'éjection et le cerclage se font en quelque sorte en temps masqué, par rapport à la durée du compactage. Cela permet de gagner en productivité.On the other hand, thanks to the press according to the invention, after the initial compaction and the first transfer, the compaction of a block of material takes place in parallel with the ejection and strapping of the block of the previous compacted materials. Thus, the ejection and the strapping are done in a way in masked time, compared to the duration of the compaction. This makes it possible to gain in productivity.

Selon le cas on peut gagner jusqu'à 50% de productivité.Depending on the case, up to 50% productivity can be gained.

Au cours des différentes étapes et sous-étapes illustrées en figures 7 à 13, une grande quantité de jus sont susceptibles de s'écouler, notamment lors du compactage.During the various stages and sub-stages illustrated in figures 7 to 13 , a large amount of juice is likely to flow, especially during compaction.

Pour récupérer ces jus, la presse P peut comprendre un bac récupérateur 66 avec un bec de vidange 68.To recover these juices, the press P can include a collecting tank 66 with a drain spout 68.

Celui-ci peut être placé sous le deuxième emplacement E2, à savoir sous le couloir de guidage. Des jus sont en effet amenés à s'écouler en quantité lors du transfert, ce dernier suivant l'étape de compactage.This can be placed under the second location E 2 , namely under the guide passage. Juices are in fact caused to flow in quantity during the transfer, the latter following the compacting step.

De plus, en cas de compactage contre la deuxième paroi 42 de coffre, des giclements sont susceptibles de se produire. Aussi, la presse P peut comprendre un cache 60 en arrière du coffre 40, pour masquer l'espace entre les rails 13 et arrêter les giclements.In addition, in the event of compaction against the second wall 42 of the trunk, squirting is likely to occur. Also, the press P can include a cover 60 behind the box 40, to hide the space between the rails 13 and stop squirting.

Ce cache 60 peut être vertical ; cela permet au jus de s'écouler vers le bas jusqu'au bac de récupération 66. Le cache peut se terminer en bas par un retour 61 en direction du bac 66 et jusqu'au-dessus de celui-ci.This cover 60 can be vertical; this allows the juice to flow downwards to the collecting tank 66. The cover may end at the bottom with a return 61 towards the tank 66 and up to the top thereof.

La presse P peut également comprendre une rampe d'écoulement 62, sous le logement de collecte 6 et le conduit de compactage 15, déclinant vers le bac 66, pour récupérer les jus issus du déplacement et compactage des ordures ménagères 0. Celle-ci peut indirectement se déverser dans une rampe intermédiaire 64, entrant jusque dans le bac 66.The press P can also include a flow ramp 62, under the collection housing 6 and the compacting duct 15, declining towards the tank 66, to recover the juice resulting from the displacement and compacting of the household waste 0. This can indirectly flow into an intermediate ramp 64, entering into the tank 66.

L'agencement horizontal de l'axe de compactage 1 et vertical de l'axe de transfert 2 facilite cette récupération des jus, et donc l'utilisation pour compacter des ordures ménagères.The horizontal arrangement of the compacting axis 1 and vertical of the transfer axis 2 facilitates this recovery of the juices, and therefore the use for compacting household waste.

L'emploi de cette presse n'est cependant pas limité à des ordures ménagères mais à tous matériaux compactables, par exemple des métaux, tel que des chutes d'aluminium.The use of this press is however not limited to household waste but to all compactable materials, for example metals, such as aluminum scraps.

La presse P peut comprendre un calculateur relié aux lignes de pression hydraulique permettant le fonctionnement des différents vérins, 10, 20, 30. Ce calculateur peut adapter les cycles de fonctionnement, notamment les durées d'exercice de la force de compactage ou l'amplitude de cette force, en fonction du type de matériau compactable. Il peut également être connecté au dispositif de liage, notamment de cerclage, pour paramétrer le nombre de cerclage. Ce dernier peut se faire au moyen de feuillard polyester ou de fil métallique.The press P can include a computer connected to the hydraulic pressure lines allowing the operation of the various jacks, 10, 20, 30. This computer can adapt the operating cycles, in particular the durations of the compaction force or the amplitude. of this force, depending on the type of compactable material. It can also be connected to the binding device, in particular the strapping device, to configure the number of strapping. The latter can be done by means of polyester strap or metal wire.

Selon un exemple de réalisation, la pression de compactage exercée lors du compactage dans le coffre 40 est de 20 kg/cm2. La force exercée sera plus ou moins grande selon le dimensionnement de la chambre de compactage.According to an exemplary embodiment, the compaction pressure exerted during compaction in the trunk 40 is 20 kg / cm 2 . The force exerted will be greater or less depending on the dimensioning of the compaction chamber.

Selon une réalisation de la chambre la largeur du conduit de compactage est comprise entre 1000 et 1400 millimètres (mm), et sa hauteur entre 700 et 1100 mm. Le dimensionnement sera adapté lors de la conception de la presse en fonction de la taille des blocs que l'on veut obtenir. En fonction de ces dimensions et des matériaux les vérins développeront plus ou moins de force. Globalement la force de transfert est 2 à 3 fois celle de la force d'éjection, et la force de compactage est de 1,5 à 2 fois celle de la force de transfert. Par exemple, la force maximale développée par le vérin de compactage peut être comprise entre 120 et 350 tonnes. Bien sûr ces valeurs sont indicatives.According to one embodiment of the chamber, the width of the compaction duct is between 1000 and 1400 millimeters (mm), and its height between 700 and 1100 mm. The dimensioning will be adapted during the design of the press according to the size of the blocks which one wants to obtain. Depending on these dimensions and the materials the jacks will develop more or less force. Overall the transfer force is 2-3 times that of the ejection force, and the compaction force is 1.5-2 times that of the transfer force. For example, the maximum force developed by the compaction cylinder can be between 120 and 350 tons. Of course these values are indicative.

La presse selon l'invention permet de produire des blocs d'une densité meilleure que celle de l'art antérieur. Notamment en sortie de cerclage, les blocs présentent des dimensions et une densité plus homogènes. La densité peut atteindre 1 t/m3 selon les matériaux compactables.The press according to the invention makes it possible to produce blocks of a better density than that of the prior art. Particularly at the end of the strapping, the blocks have more homogeneous dimensions and density. The density can reach 1 t / m 3 depending on the compactable materials.
