Description

Déconditionneur à nettoyage amélioré  Improved cleaning deconditioner
DOMAINE DE L'INVENTION L' invention concerne le tri des déchets en vue notamment de leur recyclage ou de leur élimination. L' invention se rapporte plus particulièrement à un dispositif de nettoyage d'emballages dans le cadre du retraitement de déchets issus notamment de la grande distribution. FIELD OF THE INVENTION The invention relates to the sorting of waste with a view in particular to their recycling or their elimination. The invention relates more particularly to a packaging cleaning device in the context of the reprocessing of waste resulting particularly from large-scale distribution.
ARRIERE PLAN DE L'INVENTION  BACKGROUND OF THE INVENTION
Dans le domaine du traitement des déchets issus notamment de la grande distribution, il est connu un appareil de traitement pour collecter de la matière adhérant à la surface externe d'emballages à traiter. Un tel appareil est représenté sur la figure 1 annexée.  In the field of the treatment of waste resulting in particular from large-scale distribution, it is known a treatment apparatus for collecting material adhering to the outer surface of packages to be treated. Such an apparatus is shown in the appended FIG.
Cet appareil 1 comporte un tambour cylindrique 4 rotatif autour d'un axe longitudinal Ox pourvu d'orifices 6 formant crible pour retenir les emballages et laisser passer la matière à collecter, des moyens motorisés 12 pour entraîner en rotation le tambour cylindrique 4 et un carter externe 3 pour collecter la matière issue des emballages 13 introduits dans le tambour cylindrique 4 et ayant traversé la paroi de ce tambour cylindrique 4. Optionnellement , une brosse rotative 7, également entraînée en rotation par les moyens motorisés 12, est montée dans le tambour cylindrique 4 pour brosser la surface interne de ce tambour.  This apparatus 1 comprises a cylindrical drum 4 rotatable about a longitudinal axis Ox provided with openings 6 forming a screen for retaining the packages and let the material to be collected, motorized means 12 for driving in rotation the cylindrical drum 4 and a housing 3 to collect the material from the packages 13 introduced into the cylindrical drum 4 and having passed through the wall of the cylindrical drum 4. Optionally, a rotary brush 7, also rotated by the motorized means 12, is mounted in the cylindrical drum 4 to brush the inner surface of this drum.
Ainsi, lorsqu'un emballage 13 est introduit dans cet appareil 1, il est happé par la brosse 7 pour être brossé et emmené dans la zone de contact de la brosse avec la surface interne du tambour cylindrique 4, zone dans laquelle l'emballage est soumis à un brossage intense. Ceci a pour effet de retirer les matières adhérant à la surface de l'emballage 13. Une fois que ce dernier a quitté la zone de contact, il est éjecté par la brosse 7 vers une région supérieure, pour suivre une trajectoire sensiblement circulaire, au cours de laquelle il saute au-dessus de la brosse 7 et frappe le tambour cylindrique 4, avant d'être à nouveau happé par la brosse qui le ramène dans la zone de contact pour y subir un nouveau brossage intense. A chaque saut hors de la zone de contact, l'emballage en traitement perd une portion supplémentaire des matières qui adhèrent à sa surface, celles-ci étant centrifugées lorsque l'emballage passe au-dessus de la brosse en tournoyant. Thus, when a package 13 is introduced into this apparatus 1, it is caught by the brush 7 to be brushed and taken into the contact zone of the brush with the inner surface of the cylindrical drum 4, zone in which the package is subjected to intense brushing. This has the effect of removing the adhering material from the surface of the package 13. Once this last left the contact area, it is ejected by the brush 7 to an upper region, to follow a substantially circular path, during which it jumps above the brush 7 and strikes the cylindrical drum 4, before to be caught again by the brush which brings it back into the contact zone to undergo a new intense brushing. At each jump out of the contact zone, the packaging in process loses an additional portion of the adhering materials to its surface, these being centrifuged when the package passes over the brush while spinning.
Lors du traitement d'emballages contenant des déchets filandreux -comme la viande ou de l'ananas- ou pouvant s'agglomérer facilement tels que la semoule, il se forme des bouchons (on parle de « goujons » de matière) qui viennent obstruer les orifices du tambour. Il est alors nécessaire de procéder fréquemment à des opérations de dégoujonnage du tambour. De telles opérations requièrent d'accéder à l'intérieur du tambour et de nettoyer un à un les orifices obstrués, ce qui oblige à une vidange préalable du tambour. Le temps d'immobilisation de la machine est important et les opérations de dégoujonnage impactent lourdement les coûts d'exploitation de la machine.  When treating packaging containing stringy waste - such as meat or pineapple - or can easily agglomerate such as semolina, corks are formed (referred to as "dowels" of material) which obstruct Drum holes. It is then necessary to proceed frequently with drum unstacking operations. Such operations require access to the interior of the drum and cleaning one by one the obstructed openings, which requires a prior emptying of the drum. The downtime of the machine is important and the unblocking operations have a heavy impact on the operating costs of the machine.
OBJET DE L'INVENTION OBJECT OF THE INVENTION
Le but de l'invention est de réduire les temps et /ou les coûts de dégoujonnage d'un appareil de traitement pour collecter de la matière adhérant une surface d'emballage.  The object of the invention is to reduce the time and / or the costs of dewatering a treatment apparatus to collect material adhering to a packaging surface.
RESUME DE L'INVENTION SUMMARY OF THE INVENTION
A cet effet, on prévoit un appareil de traitement pour collecter de la matière adhérant à une surface d'emballages à traiter comme déchets, l'appareil de traitement comportant un tambour cylindrique rotatif autour d'un axe longitudinal et pourvu d'orifices pour former un crible retenant les emballages et laissant passer la matière à collecter et des moyens motorisés pour entraîner en rotation le tambour rotatif. Selon l'invention, l'appareil de traitement comprend également des moyens de dégoujonnage pour désobstruer au moins partiellement des orifices lors de la rotation du tambour cylindrique. Ainsi, le dégoujonnage des orifices a lieu au cours de la rotation du tambour et les temps d'immobilisation de l'appareil de traitement pour effectuer le dégoujonnage sont réduits, ce qui améliore la rentabilité de l'appareil de traitement. For this purpose, there is provided a treatment apparatus for collecting material adhering to a surface of packaging to be treated as waste, the apparatus for treatment comprising a cylindrical drum rotatable about a longitudinal axis and provided with orifices to form a sieve retaining the packages and allowing the material to be collected and motorized means for rotating the rotary drum. According to the invention, the treatment apparatus also comprises degoujonnage means for at least partially unobstructed openings during the rotation of the cylindrical drum. Thus, the unblocking of the holes takes place during the rotation of the drum and the downtimes of the processing apparatus to perform the dowel are reduced, which improves the cost effectiveness of the treatment apparatus.
Un dispositif particulièrement robuste est obtenu lorsque les moyens de dégoujonnage comprennent une roue montée à rotation selon un premier axe et pourvue d'au moins un élément en saillie radiale destiné à s'engager dans un des orifices du tambour.  A particularly robust device is obtained when the dowel means comprise a wheel rotatably mounted along a first axis and provided with at least one radially projecting element intended to engage in one of the orifices of the drum.
Le dispositif est particulièrement fiable lorsque le premier axe est sensiblement parallèle à l'axe longitudinal .  The device is particularly reliable when the first axis is substantially parallel to the longitudinal axis.
Le volume de déchets pouvant être chargé dans le tambour est augmenté lorsque la roue est montée à l'extérieur du tambour cylindrique.  The volume of waste that can be loaded into the drum is increased when the wheel is mounted outside the cylindrical drum.
La construction de la roue est particulièrement économique lorsque la roue comprend au moins un disque monté à rotation selon le premier axe ou une pluralité de disques entretoisés montés à rotation selon le premier axe . The construction of the wheel is particularly economical when the wheel comprises at least one disk rotatably mounted along the first axis or a plurality of spaced disks mounted to rotate along the first axis.
Avantageusement, les orifices sont chacun délimités par quatre faces, la construction du tambour et de la roue étant simplifié lorsque les quatre faces sont parallèles deux à deux . Advantageously, the orifices are each delimited by four faces, the construction of the drum and the wheel being simplified when the four faces are parallel in pairs.
Une construction simple de la roue, par exemple par oxycoupage d'une tôle, peut être réalisée lorsque l'élément en saillie radiale est une dent. Le dégoujonnage des orifices est plus efficace lorsqu'une hauteur de la dent est supérieure à une épaisseur du tambour cylindrique. A simple construction of the wheel, for example by flame cutting a sheet, can be achieved when the radially projecting element is a tooth. The unblocking of the orifices is more effective when a height of the tooth is greater than a thickness of the cylindrical drum.
Une construction du tambour par soudage de tôles cintrées peut être mise en œuvre lorsque la roue comprend au moins deux éléments en saillie radiale successifs qui s'étendent respectivement selon des directions radiales formant un premier angle, et que la roue comprend également au moins deux éléments en saillie radiale successifs s' étendant respectivement selon des directions radiales formant un deuxième angle, le deuxième angle étant un multiple entier supérieur à un du premier angle. A construction of the drum by welding bent sheets can be implemented when the wheel comprises at least two successive radial projecting elements which respectively extend in radial directions forming a first angle, and that the wheel also comprises at least two elements. successive radial projections extending respectively in radial directions forming a second angle, the second angle being an integer multiple greater than one of the first angle.
Avantageusement, l'appareil de traitement comprend un peigne dont les dents s'étendent entre deux disques successifs de la roue.  Advantageously, the treatment apparatus comprises a comb whose teeth extend between two successive disks of the wheel.
L'évacuation des déchets est facilitée lorsqu'un éjecteur à emballages est agencé pour coulisser à l'intérieur du tambour selon une direction sensiblement parallèle à l'axe longitudinal.  Disposal of waste is facilitated when a packaged ejector is arranged to slide inside the drum in a direction substantially parallel to the longitudinal axis.
Avantageusement encore, l'appareil comprend des moyens de compression contre une face interne du tambour cylindrique et qui sont montés dans le tambour cylindrique au voisinage immédiat de la surface interne de celui-ci, les moyens de compressions étant motorisés pour être entraînés en rotation autour d'un axe sensiblement parallèle à l'axe longitudinal. Les moyens de compression créent alors un guidage des déchets dans un espace allant en se réduisant au fur et à mesure que le déchet approche de la paroi du tambour. Ceci assure une compression de l'emballage et son contenu contre la paroi du tambour et donc l'extraction du contenu hors de son emballage. Avantageusement, les emballages sont introduits dans le tambour cylindrique via une trémie de chargement comportant une ouverture de chargement et une ouverture d'alimentation faisant face à un port d'alimentation débouchant dans le tambour cylindrique. Les opérations de chargement sont facilitées lorsque la trémie de chargement est agencée sur un châssis de l'appareil de traitement pour coulisser entre une première position dans lequel l'ouverture d'alimentation est éloignée du port d'alimentation et une deuxième position dans laquelle l'ouverture d'alimentation fait face au port d' alimentation . Advantageously, the apparatus comprises compression means against an internal face of the cylindrical drum and which are mounted in the cylindrical drum in the immediate vicinity of the inner surface thereof, the compression means being motorized to be rotated around an axis substantially parallel to the longitudinal axis. The compression means then create a guidance of the waste in a space which becomes smaller as the waste approaches the wall of the drum. This ensures compression of the package and its contents against the drum wall and thus the extraction of the contents out of its packaging. Advantageously, the packages are introduced into the cylindrical drum via a loading hopper comprising a loading opening and a feed opening facing a feed port opening into the cylindrical drum. The loading operations are facilitated when the loading hopper is arranged on a frame of the processing apparatus to slide between a first position in which the supply opening is remote from the supply port and a second position in which the The power supply is facing the power port.
Les performances de la machine pour différents types de déchets peuvent être facilement évaluées lorsque l'appareil comprend des moyens de pesage de la trémie dans sa deuxième position.  The performance of the machine for different types of waste can be easily evaluated when the apparatus comprises weighing means of the hopper in its second position.

DESCRIPTION DETAILLEE DE L'INVENTION En référence aux figures 2 à 6, l'appareil de traitement selon l'invention, repéré 1, comporte un châssis 2 sous forme d'une structure formée par des profilés en acier mécano soudés, portant un carter 3 articulé en acier (le carter 3 est ici partiellement représenté à des fins de clarté) . DETAILED DESCRIPTION OF THE INVENTION With reference to FIGS. 2 to 6, the treatment apparatus according to the invention, marked 1, comprises a frame 2 in the form of a structure formed by mechanically welded steel profiles, carrying a casing 3. articulated steel (the housing 3 is here partially represented for the sake of clarity).
Le carter 3 renferme un tambour 4 cylindrique ou trommel 4 sous forme d'un cylindre de tôle ajouré par une série d'orifices 6 sur la grande majorité de sa surface pour constituer un crible rotatif autour d'un axe longitudinal Ox . Une porte 5 articulée selon un axe horizontal perpendiculaire à l'axe longitudinal Ox, ferme la première extrémité 4.1 du trommel 4. Une brosse 7 cylindrique rotative ainsi qu'un rouleau 20 sont montés à l'intérieur du trommel 4. Le trommel 4 renferme également un éjecteur 30 à emballage sous la forme d'un disque 31 relié à une tige 32 d'un piston 33, la tige 32 étant montée pour coulisser dans le trommel 4 selon une direction sensiblement parallèle à l'axe longitudinal Ox . Le disque 32 comprend une découpe 34 pour échapper à la brosse 7 ainsi qu'un rabat 35 qui dirige les emballages projetés par la brosse 7 contre le rabat 35 vers la première extrémité 4.1 du trommel 4, dirigeant alors les emballages vers la sortie du trommel 4. The casing 3 encloses a cylindrical drum 4 or trommel 4 in the form of a sheet metal cylinder pierced by a series of orifices 6 over the vast majority of its surface to form a rotary screen around an axis longitudinal Ox. A door 5 articulated along a horizontal axis perpendicular to the longitudinal axis Ox, closes the first end 4.1 of the trommel 4. A rotating cylindrical brush 7 and a roller 20 are mounted inside the trommel 4. The trommel 4 encloses also a packaged ejector 30 in the form of a disc 31 connected to a rod 32 of a piston 33, the rod 32 being mounted to slide in the trommel 4 in a direction substantially parallel to the longitudinal axis Ox. The disc 32 comprises a cutout 34 to escape the brush 7 and a flap 35 which directs the packages projected by the brush 7 against the flap 35 towards the first end 4.1 of the trommel 4, then directing the packages towards the exit of the trommel 4.
Une trémie 40 sensiblement en forme de pyramide renversée comprend une ouverture de chargement 41 et une ouverture d'alimentation 42 faisant face à un port 8 d'alimentation débouchant dans le trommel 4. Une vis sans fin 43 motorisée s'étend dans la trémie 40 pour diriger les emballages 13 vers l'ouverture d'alimentation 42 et alimenter le trommel 4 en déchets. La trémie 40 comprend quatre roues 44.1 à 44.4 placées à proximité des angles de l'ouverture de chargement 41 de la trémie 40. Ces roues 44.1 à 44.4 coopèrent avec un premier et un deuxième rail 45.1 et 45.2 solidaires du châssis 2 pour que la trémie 40 puisse coulisser entre une première position (représentée en figure 7) et une deuxième position (représentée en figure 8) . Dans la première position de la trémie 40, l'ouverture d'alimentation 42 de la trémie 40 est éloignée du port d'alimentation 8. A hopper 40 substantially in the form of a reverse pyramid comprises a loading opening 41 and a feed opening 42 facing a feed port 8 opening into the trommel 4. A motorized worm 43 extends into the hopper 40 to direct the packages 13 to the feed opening 42 and feed the trommel 4 waste. The hopper 40 comprises four wheels 44.1 to 44.4 placed near the corners of the loading opening 41 of the hopper 40. These wheels 44.1 to 44.4 cooperate with a first and a second rail 45.1 and 45.2 secured to the frame 2 so that the hopper 40 can slide between a first position (shown in Figure 7) and a second position (shown in Figure 8). In the first position of the hopper 40, the feed opening 42 of the hopper 40 is remote from the feed port 8.
Dans sa deuxième position, l'ouverture d'alimentation 42 de la trémie 40 fait face au port 8 d'alimentation et chacune des roues 44.1 à 44.4 repose respectivement sur une jauge piezo-résistive 46.1 à 46.4. Le trommel 4 est entraîné en rotation autour de l'axe longitudinal Ox à l'aide d'un moteur non représenté sur les figures et est guidé à chacune de ses extrémités par deux galets rotatifs 11. La brosse 7 est entraînée en rotation par un moteur 12 qui est porté par le châssis 2, à l'une des extrémités de l'appareil 1. La vitesse de rotation de la brosse 7 est, préfèrentiellement , très supérieure à celle du trommel 4. In its second position, the feed opening 42 of the hopper 40 faces the supply port 8 and each of the wheels 44.1 to 44.4 is respectively based on a piezo-resistive gauge 46.1 to 46.4. The trommel 4 is rotated about the longitudinal axis Ox to using a motor not shown in the figures and is guided at each of its ends by two rotary rollers 11. The brush 7 is rotated by a motor 12 which is carried by the frame 2, to one of ends of the apparatus 1. The speed of rotation of the brush 7 is preferably much greater than that of the trommel 4.
Le rouleau 20 est entraîné en rotation autour d'un axe sensiblement parallèle à l'axe longitudinal Ox par un moteur 23 et vient améliorer la récupération des matières contenues dans les emballages. Le rouleau 20, qui a la forme générale d'un cylindre, est monté à l'intérieur du trommel 4 pour rouler sur la surface intérieure du trommel 4. Le rouleau 20, mieux visible sur les figures 5 et 6, comporte deux tronçons successifs sur sa longueur : un premier tronçon dit « de déconditionnement » 21 ayant une surface externe hérissée de pointes agencées de sorte à extirper les matières des emballages, et possiblement déchiqueter ces derniers, et un second tronçon dit « de laminage » 22 ayant une surface externe lisse agencée de sorte à forcer le passage des matières à collecter à travers le trommel 4.  The roller 20 is rotated about an axis substantially parallel to the longitudinal axis Ox by a motor 23 and improves the recovery of the materials contained in the packages. The roll 20, which has the general shape of a cylinder, is mounted inside the trommel 4 to roll on the inner surface of the trommel 4. The roll 20, better visible in FIGS. 5 and 6, comprises two successive sections. along its length: a first section said "deconditioning" 21 having an outer surface bristling with tips arranged to remove the materials packaging, and possibly shredding them, and a second section called "rolling" 22 having an outer surface smooth arranged to force the passage of materials to collect through the trommel 4.
Les jauges piezo-résistives 45.1 à 45.4, la motorisation du trommel 4, le moteur 12 de la brosse 7, le moteur 23 du rouleau de compression, le piston 33, la motorisation de la vis sans fin 43 ainsi que d'autres équipements électriques (détecteur de fermeture de la porte 5 etc..) sont reliés à une unité de commande 80 de l'appareil de traitement 1 qui est pourvue d'une mémoire 81, d'un afficheur tactile 82 et de moyens de communication 83 sans fil (ici une interface Wi-Fi) .  The piezo-resistive gauges 45.1 to 45.4, the motorization of the trommel 4, the motor 12 of the brush 7, the motor 23 of the compression roller, the piston 33, the motorization of the worm gear 43 and other electrical equipment (Door closing detector 5 etc.) are connected to a control unit 80 of the processing apparatus 1 which is provided with a memory 81, a touch display 82 and 83 wireless communication means. (here a Wi-Fi interface).
Comme visible sur les figures 9 à 11, les orifices 6 du trommel 4 ont une section sensiblement en forme de parallélépipède et sont délimités par quatre faces 6.1, 6.2, 6.3 et 6.4 parallèles deux à deux. Ainsi, les faces 6.1 et 6.3 sont parallèles entre elles et s'étendent dans un plan sensiblement orthogonal à l'axe longitudinal Ox . Les faces 6.2 et 6.4 s'étendent dans des plans comprenant l'axe longitudinal Ox . Le trommel 4 est, ici, fabriqué à partir de trois tôles 50, 51 et 52 en acier S700 à haute limite élastique d'épaisseur e. Les tôles 50, 51 et 52 sont tout d'abord cintrées avant d'être assemblées par soudage pour réaliser un cylindre 53 comprenant trois soudures longitudinales 54, 55 et 56. Ce cylindre 53 est ensuite placé dans une machine de découpe par jet d'eau hyperbare pour réaliser les orifices 6. La précision d'implantation des orifices 6 l'un par rapport à l'autre est de l'ordre de 0.2 millimètres. Préfèrentiellement les orifices 6 ont une section en forme de quadrilatère dont les côtés ont des dimensions comprises entre cinq et huit millimètres pour le petit côté et huit et douze millimètres pour le grand côté. Des sections de cinq millimètres par huit millimètres et de huit millimètres par douze millimètres sont très préférées. Les orifices 6 sont implantés sur le trommel 4 selon un pas p compris entre neuf et dix-huit millimètres. Comme visible en figure 10, les soudures longitudinales 54, 55 et 56 ne comportent pas d'orifices 6. Ainsi, les séries longitudinales 6.10 et 6.20 d'orifices 6 situés de part et d'autre de la soudure 54 sont séparés d'une distance D égale à deux fois le pas p. Le trommel 4 représenté sur la figure 10 a un diamètre d'environ huit cent millimètres et comporte cinquante rangées de cent trente-deux orifices 6. Les cent trente- deux orifices 6 sont réparties en trois secteurs de quarante-quatre orifices 6 chacun réalisés sur les tôles 50, 51 et 52. Ces trois secteurs sont séparés les uns des autres par une première, une deuxième et une troisième zone 57, 58 et 59 dans lesquelles s'étendent respectivement les soudures longitudinales 55, 55 et 56. L'appareil de traitement 1 comprend des moyens de dégoujonnage des orifices 6 lors de la rotation du trommel 4, ici sous la forme d'une roue 60 montée à rotation selon un premier axe 61 s' étendant sensiblement parallèlement à l'axe longitudinal Ox . La roue 60 comprend cinquante disques 62 tous identiques et séparés les uns des autres par des entretoises. Chaque disque 62 est solidaire en rotation d'un arbre 63 cannelé et possède des rainures radiales 64 coopérant avec les cannelures 65 de l'arbre 63. Chaque disque 62 comprend un cylindre de pied 66 en saillie duquel viennent des dents 67 de hauteur h, ici supérieure à l'épaisseur e du trommel 4. As shown in Figures 9 to 11, the orifices 6 of the trommel 4 have a substantially parallelepiped-shaped section and are delimited by four faces 6.1, 6.2, 6.3 and 6.4 parallel in pairs. So, the faces 6.1 and 6.3 are parallel to each other and extend in a plane substantially orthogonal to the longitudinal axis Ox. The faces 6.2 and 6.4 extend in planes comprising the longitudinal axis Ox. Trommel 4 is, here, manufactured from three sheets 50, 51 and 52 S700 steel with high elastic limit e thickness. The sheets 50, 51 and 52 are first bent before being assembled by welding to produce a cylinder 53 comprising three longitudinal welds 54, 55 and 56. This cylinder 53 is then placed in a jet cutting machine. hyperbaric water to achieve the orifices 6. The implantation accuracy of the orifices 6 relative to each other is of the order of 0.2 millimeters. Preferably the orifices 6 have a quadrilateral-shaped section whose sides have dimensions of between five and eight millimeters for the short side and eight and twelve millimeters for the long side. Sections of five millimeters by eight millimeters and eight millimeters by twelve millimeters are very preferred. The orifices 6 are located on the trommel 4 in a pitch p between nine and eighteen millimeters. As can be seen in FIG. 10, the longitudinal welds 54, 55 and 56 do not comprise orifices 6. Thus, the longitudinal series 6.10 and 6.20 of orifices 6 situated on either side of the weld 54 are separated from one another. distance D equal to twice the pitch p. The trommel 4 shown in FIG. 10 has a diameter of about eight hundred millimeters and comprises fifty rows of one hundred and thirty-two orifices 6. The one hundred and thirty-two orifices 6 are distributed in three sectors of forty-four orifices 6 each made on the sheets 50, 51 and 52. These three sectors are separated from each other by a first, a second and a third zone 57, 58 and 59 in which the longitudinal welds 55, 55 and 56 respectively extend. The processing apparatus 1 comprises means for degoujonnage the orifices 6 during the rotation of the trommel 4, here in the form of a wheel 60 rotatably mounted along a first axis 61 extending substantially parallel to the longitudinal axis Ox . The wheel 60 comprises fifty discs 62 all identical and separated from each other by spacers. Each disc 62 is integral in rotation with a splined shaft 63 and has radial grooves 64 cooperating with the splines 65 of the shaft 63. Each disc 62 comprises a foot cylinder 66 projecting from which teeth 67 have a height h, here greater than the thickness e of the trommel 4.
Comme visible en figure 9, le disque 62 comprend quarante-quatre dents 67.1 à 67.44 s' étendant chacune selon une direction radiale 68.1 à 68.44. Les directions radiales 68.1 à 68.44 des quarante-quatre premières dents 67 s'étendent, l'une par rapport à la suivante, selon un premier angle i égal à huit degrés et couvrent donc un secteur angulaire de trois cent quarante-quatre degrés. As seen in Figure 9, the disk 62 includes forty-four teeth 67.1 to 67.44 each extending in a radial direction 68.1 to 68.44. The radial directions 68.1 to 68.44 of the first forty-four teeth 67 extend, with respect to the following, at a first angle i equal to eight degrees and thus cover an angular sector of three hundred and forty-four degrees.
Le disque 62 comprend également une quarante quatrième dent 67.44 et une première dent 67.1 successives dont les quarante quatrième et première directions radiales 68.44 et 68.1 forment un deuxième angle (¾ égal à seize degrés. La roue 60 possède ainsi un secteur angulaire d' engrènement 69 et un deuxième secteur angulaire d'échappement 70 couvrant le deuxième angle (¾. La valeur de l'angle (¾ est, ici, égale au double de la valeur de l'angle i . The disk 62 also includes a fourth tooth 67.44 and a first tooth 67.1 successive whose forty fourth and first radial directions 68.44 and 68.1 form a second angle (¾ equal to sixteen degrees.The wheel 60 thus has an angular sector of meshing 69 and a second exhaust angular sector 70 covering the second angle (¾) The value of the angle (¾ is, here, equal to twice the value of the angle i.
La roue 60 est montée à l'extérieur du trommel 4 de manière à ce que les dents 67 de chacun des disques 62 coopèrent avec les orifices 6 du trommel 4 à la manière de deux roues dentées. The wheel 60 is mounted on the outside of the trommel 4 so that the teeth 67 of each of the disks 62 cooperate with the orifices 6 of the trommel 4 in the manner of two toothed wheels.
Un peigne 71 solidaire du châssis 2 est placé à proximité de la roue 60 de manière à ce que ses dents 72 s'étendent entre deux disques 62 successifs de la roue 60. A comb 71 integral with the frame 2 is placed close to the wheel 60 so that its teeth 72 extend between two successive disks 62 of the wheel 60.
En fonctionnement, l'utilisateur amène la trémie 40 dans sa première position et charge celle-ci en emballages 13 par l'ouverture 41 de chargement. Une fois la trémie 40 chargée, l'utilisateur repousse celle-ci dans sa deuxième position. Les jauges piezo-résistives 46.1 à 46.4 transmettent à l'unité de commande 80 un signal électrique représentatif de la charge à laquelle elles sont soumises. L'unité de commande 80 en déduit une masse d'emballages 13 chargée dans la trémie 40, l'enregistre dans la mémoire 81 et l'affiche sur l'afficheur 82. Optionnellement , cette quantité est transmise par les moyens de communication sans-fil 83 à un serveur distant. L'unité de commande 80 commande la mise en rotation du trommel 4, de la brosse 7 et du rouleau 20. L'unité de commande 80 ordonne ensuite la mise en route de la vis sans fin 43 jusqu'à ce qu'une quantité déterminée d'emballages 13 -pouvant être mesurée à l'aide des jauges piezo-résistives 46.1 à 46.4- soit introduite dans le trommel 4. La rotation du trommel 4 provoque la rotation de la roue 60 et l'introduction des dents 67.1 à 67.44 dans les orifices 6 lors de la rotation du trommel 4. Le rapport des diamètres primitifs de la roue 60 et du trommel 4 étant entier (ce rapport est ici de 3) , la roue 60 présente systématiquement le secteur d'échappement 70 face à l'une des soudures 54, 55 ou 56, garantissant une absence de collision entre une dent 67 et une des soudures 54, 55 ou 56. Les goujons de matière évacués des orifices 6 par les dents 67 tombent dans le trommel 4 où la brosse 7 et le rouleau 20 les désagrègent et les évacuent au travers des orifices 6. L'évacuation des emballages 13 hors du trommel 4 peut se faire de plusieurs manières. Selon le degré de salissure des emballages 13, l'appareil de traitement 1 peut fonctionner avec la porte 5 totalement ou partiellement ouverte, l'évacuation des emballages 13 se faisant au fur et à mesure de leur traitement. Il est également possible de fermer la porte 5 pendant le traitement des emballages 13 et , à l'issue d'une durée de traitement prédéfinie, ouvrir la porte 5 et actionner le vérin 33 pour provoquer une sortie de l'éjecteur à emballages 31 qui coulisse à l'intérieur du trommel 4 et pousse les emballages 13 hors du trommel 4 par la première extrémité 4.1. L'unité de commande 80 peut alors être actionnée pour commander la vis sans fin 43 afin de procéder à un nouveau chargement du trommel 4. In operation, the user brings the hopper 40 into its first position and loads it into packages 13 through the loading aperture 41. Once the hopper 40 is loaded, the user pushes the latter into its second position. The piezo-resistive gages 46.1 to 46.4 transmit to the control unit 80 an electrical signal representative of the load to which they are subjected. The control unit 80 derives a mass of packaging 13 loaded into the hopper 40, stores it in the memory 81 and displays it on the display 82. Optionally, this quantity is transmitted by the communication means without thread 83 to a remote server. The control unit 80 controls the rotation of the trommel 4, the brush 7 and the roller 20. The control unit 80 then orders the start of the worm 43 until a quantity determined by packaging 13 -can be measured using piezo-resistive gages 46.1 to 46.4- be introduced into the trommel 4. The rotation of the trommel 4 causes the rotation of the wheel 60 and the introduction of the teeth 67.1 to 67.44 in the orifices 6 during the rotation of the trommel 4. The ratio of the primitive diameters of the wheel 60 and the trommel 4 being entire (this ratio is here 3), the wheel 60 systematically has the exhaust sector 70 facing the one of the welds 54, 55 or 56, guaranteeing an absence of collision between a tooth 67 and one of the welds 54, 55 or 56. The material studs discharged from the orifices 6 by the teeth 67 fall into the trommel 4 where the brush 7 and the roller 20 disintegrate and evacuate through the orifices 6. L Disposal of packages 13 outside the trommel 4 can be done in several ways. Depending on the degree of soiling of the packages 13, the treatment apparatus 1 can operate with the door 5 fully or partially open, the evacuation of the packaging 13 being made as and when their treatment. It is also possible to close the door 5 during the treatment of the packages 13 and, after a predefined processing time, open the door 5 and actuate the cylinder 33 to cause an output of the packaging ejector 31 which slides inside the trommel 4 and pushes the packages 13 out of the trommel 4 by the first end 4.1. The control unit 80 can then be actuated to control the worm screw 43 in order to re-load the trommel 4.
Les dimensions des orifices 6 du tambour 4 sont choisies pour retenir les emballages 13, tout en laissant passer les matières qu'ils contiennent et qui adhèrent à ces emballages 13. Le passage des matières en question est encore facilité par l'effet centrifuge de la rotation du trommel 4, de sorte que ces matières se retrouvent ensuite dans le carter 3, les emballages 13 étant quant à eux retenus à 1 ' intérieur du trommel 4. The dimensions of the orifices 6 of the drum 4 are chosen to retain the packages 13, while allowing the materials they contain to adhere to these packagings 13. The passage of the materials in question is further facilitated by the centrifugal effect of the rotation of the trommel 4, so that these materials are then found in the housing 3, the packaging 13 being in turn retained within the trommel 4.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit mais englobe toute variante entrant dans le champ de l'invention telle que définie par les revendications.  Of course, the invention is not limited to the embodiment described but encompasses any variant within the scope of the invention as defined by the claims.
En particulier, bien qu' ici la compression des déchets est assurée par un rouleau cylindrique monté à rotation, l'invention s'applique également à d'autres moyens de compression comme par exemple un rouleau cylindrique fixe, un racloir plan fixe positionné pour former un aigle aigu avec la surface interne du tambour, ou une tôle fixe ayant une section transversale sensiblement en forme de virgule. Un tel racloir ou une telle tôle pourra présenter une portion pourvue de griffes (première fonction de déconditionnement) et une deuxième portion de guidage (laminage) . Plus généralement, les moyens de compression créent un guidage des déchets dans un espace allant en se réduisant au fur et à mesure que le déchet approche de la surface interne du tambour. Les moyens de compression de l'invention peuvent également comprendre un cône de compression, dont l'axe de rotation serait parallèle ou non à l'axe de rotation du tambour, un cylindre de courbe directrice octogonale ou quelconque. In particular, although here the compression of waste is ensured by a cylindrical roller rotatably mounted, the invention is also applicable to other compression means such as for example a fixed cylindrical roller, a fixed plane scraper positioned to form an acute eagle with the inner surface of the drum, or a fixed sheet having a substantially comma-shaped cross section. Such a scraper or such a sheet may have a portion provided with claws (first deconditioning function) and a second guide portion (rolling). More generally, the compression means create a guidance of the waste in a space becoming smaller as the waste approaches the inner surface of the drum. The compression means of the invention may also comprise a compression cone, the axis of rotation of which would be parallel or not to the axis of rotation of the drum, an octagonal guide curve cylinder or any other.
