Description

On sait que le vidage de bacs de déchets se fait généralement en utilisant un camion de collecte, muni d'un bras de levage, capable de lever et de faire pivoter le bac de déchets afin de le vider dans une benne du camion de collecte.It is known that the emptying of garbage bins is generally done by using a collection truck, equipped with a lifting arm, capable of lifting and rotating the garbage bin in order to empty it into a bin of the collection truck.

II peut arriver qu'un bac soit reçu par le camion mais qu'il ne soit pas vidé entièrement, voire qu'il ne soit pas vidé du tout, pour des raisons volontaires ou involontaires. Par exemple, de façon volontaire, le camion de collecte peut reconnaître le bac d'un propriétaire n'ayant pas réglé ses factures et bloquer le procédé de vidage, ou encore, de façon involontaire, un dysfonctionnement du bras de levage peut empêcher le vidage du bac. Or, il est intéressant de savoir si un bac qui a été reçu par le camion de collecte a effectivement été vidé ou non, par exemple pour alerter les manipulateurs du bac, ou encore pour ne pas facturer un vidage lorsque celui-ci n'a pas eu lieu.It may happen that a container is received by the truck but it is not emptied completely, or it is not emptied at all, for voluntary or involuntary reasons. For example, on a voluntary basis, the collection truck can recognize the tank of an owner who has not paid his bills and block the emptying process, or, unintentionally, a malfunction of the lift arm can prevent emptying Tray. However, it is interesting to know if a ferry that has been received by the collection truck has actually been emptied or not, for example to alert the manipulators of the tray, or to not charge a dump when it has not not occurred.

La présente invention a notamment pour but de fournir un dispositif de collecte de déchets assurant un meilleur contrôle du procédé de vidage.The present invention is intended in particular to provide a waste collection device providing better control of the emptying process.

A cet effet, l'invention a pour objet un dispositif de collecte de déchets comportant des moyens de déplacement d'un bac de déchets entre une position dite position de réception et une position dite position de vidage, dans laquelle le bac est incliné de façon à faire tomber les déchets dans le dispositif de collecte, le dispositif de collecte comportant en outre des moyens dits de détection du vidage, capables de détecter que le bac a été déplacé jusqu'à la position de vidage.For this purpose, the subject of the invention is a device for collecting waste comprising means for moving a waste container between a position known as the receiving position and a position called the emptying position, in which the container is inclined in such a way to drop the waste into the collection device, the collection device further comprising so-called emptying detection means, capable of detecting that the tray has been moved to the emptying position.

Les moyens de détection du vidage permettent de savoir si un bac de déchets reçu par le dispositif de collecte a été manipulé par ce dernier jusqu'à atteindre sa position de vidage, et donc de savoir si le bac a effectivement été vidé. Si les moyens de détection ne détectent pas que le bac a été déplacé jusqu'à la position de vidage, on peut en déduire que le vidage n'a pas eu lieu, et ensuite utiliser cette information.The emptying detection means make it possible to know whether a waste container received by the collection device has been manipulated by the latter to reach its emptying position, and therefore to know if the container has indeed been emptied. If the detection means do not detect that the tray has been moved to the emptying position, it can be deduced that the dump has not occurred, and then use this information.

Par exemple, on peut déclencher un avertissement au manipulateur du bac de déchets, qui peut alors présenter à nouveau le bac devant le dispositif de collecte afin de remettre en oeuvre le procédé de vidage.For example, it is possible to trigger a warning to the handler of the garbage bin, who can then present the bin in front of the collection device in order to carry out the emptying process.

Selon un autre exemple, on peut enregistrer l'information selon laquelle le vidage a ou n'a pas eu lieu. Cette démarche est particulièrement intéressante dans le cadre d'un service qui facture les propriétaires des bacs en fonction du nombre de vidages effectués, puisqu'elle permet d'éviter les erreurs de facturation.In another example, information may be recorded that the dump has or has not occurred. This approach is particularly interesting in the context of a service that charges the owners of bins according to the number of emptying operations, since it avoids billing errors.

Le dispositif de collecte proposé est particulièrement avantageux du fait que, jusqu'à présent sur les dispositifs traditionnels, on ne disposait pas d'une information sur l'étape précise de vidage, mais éventuellement d'une information indiquant que le procédé de levage a été commencé. Obtenir l'indication que le bac de déchets a atteint sa position de vidage ou non permet de rendre compte de façon plus fiable des opérations qui ont eu effectivement lieu.The proposed collection device is particularly advantageous because, until now on the traditional devices, information on the precise emptying step was not available, but possibly information indicating that the lifting process been started. Obtain an indication that the waste bin has reached its position of dump or not allows reporting more reliably of the operations that actually took place.

Le dispositif de collecte peut en outre comporter l'une ou plusieurs des caractéristiques suivantes.

  • Les moyens de détection du vidage comprennent des moyens de mesure d'une grandeur caractéristique de la position des moyens de déplacement ou du bac, tel qu'un capteur. Ce capteur permet ainsi d'indiquer que les moyens de déplacement, donc le bac, prennent la position de vidage du bac. Ce capteur de position peut être par exemple un capteur indiquant la hauteur des moyens de déplacement ou du bac.
  • Les moyens de détection du vidage comprennent des moyens de mesure de l'inclinaison du bac de déchets ou des moyens de déplacement, par exemple un capteur d'angle, ces moyens de mesure étant de préférence solidaires en déplacement avec des moyens de préhension du bac de déchets. Ainsi, on peut déterminer si le bac a une inclinaison correspondant à l'inclinaison nécessaire au vidage complet du bac, c'est-à-dire à l'inclinaison de la position de vidage. En effet, pour un dispositif de collecte donné et pour une taille de bac de déchets donnée, il est possible de déterminer une inclinaison seuil du bac, suffisante pour que les déchets se vident sous l'effet de la force de gravité. Ainsi, si l'inclinaison mesurée est inférieure à la valeur seuil, on peut considérer qu'il n'y a pas eu de vidage des déchets, et si l'inclinaison est supérieure à la valeur seuil, qu'il y en a eu un.
  • Les moyens de détection du vidage comprennent un capteur de contact disposé sur une barre d'amortissement du bac en position de vidage.
  • Le dispositif de collecte comporte en outre des moyens d'identification du bac de déchets, par exemple d'identification par radiofréquence de type RFID (Radio Frequency IDentification). L'identification du bac permet ainsi d'associer à un bac donné, ou à son propriétaire, l'information selon laquelle un vidage a eu lieu ou non, en vue d'une facturation correcte du propriétaire, cette information étant fournie notamment par les moyens de détection du vidage. Une facturation satisfaisante des propriétaires des bacs de déchets en fonction du nombre de vidages effectués permet d'encourager les citoyens à générer moins de déchets.
  • Les moyens d'identification du bac comprennent une antenne RFID logée dans un boîtier, et les moyens de détection du vidage sont logés dans un même boîtier que l'antenne RFID. Ainsi, on utilise un unique boîtier pour protéger l'antenne RFID et les moyens de détection. Outre le fait que l'on simplifie l'agencement du dispositif de collecte, une telle configuration génère peu de modifications des dispositifs de collecte actuellement utilisés et déjà munis d'une antenne RFID. En d'autres termes, la fonction de détection du vidage peut être mise en oeuvre à moindre coûts sur la majorité des dispositifs de collecte.
  • Le dispositif comprend des moyens de stoppage du déplacement du bac de déchets, activés en fonction de l'identification fournie par les moyens d'identification. Ces moyens de stoppage sont activés par exemple lorsque le bac reçu par le dispositif de collecte ne présente pas d'étiquette RFID, ou encore lorsque le bac identifié fait partie d'une « liste noire », pour laquelle on refuse d'effectuer le vidage. II est particulièrement intéressant de disposer des moyens de détection du vidage dans ce cas, car il peut arriver que les moyens de stoppage se déclenchent juste avant ou juste après le vidage du bac, ou encore qu'ils ne se déclenchent pas du tout lorsque le signal de stoppage n'a pas été reçu par le dispositif de collecte ou lorsqu'il subit un disfonctionnement. Ainsi, le fait que les moyens de stoppage aient été activés ne signifie pas forcément que le bac n'a pas été vidé, et il est donc intéressant, pour une facturation plus fiable, de déterminer si le vidage a été effectué.
  • Le dispositif de collecte comporte en outre des moyens de mesure du poids du bac de déchets avant son vidage. La mesure du poids du bac permet de facturer le propriétaire du bac en fonction de la quantité de déchets qui se trouvent dans les bacs et qui ont effectivement été vidés. On assure donc une facturation plus fiable du propriétaire du bac, puisqu'un vidage qui n'aura pas eu lieu ne sera pas facturé, alors même qu'une pesée a eu lieu préalablement. Un avantage particulier à la coexistence des moyens de mesure du poids et des moyens de détection du vidage réside dans le fait que, si l'un de ces deux moyens est défectueux, ce qui peut arriver dans un environnement relativement sale tel que la collecte de déchets, tout particulièrement pour ce qui concerne les moyens de mesure du poids dont les cellules sont fragiles et fréquemment abîmées, on conserve une information pertinente utilisable pour la facturation du propriétaire du bac, soit le poids des déchets pesés, soit l'information selon laquelle un vidage a été effectué.
  • Le dispositif de collecte comporte des moyens d'avertissement activés lorsqu'un bac n'a pas été déplacé jusqu'à sa position de vidage. Ces moyens d'avertissement peuvent prendre différentes formes, sonores, visuelles, de façon que les manipulateurs du bac de déchets puissent constater qu'un vidage n'a pas été effectué ou bien de manière à effectuer de nouveau l'opération de vidage.
  • Le dispositif comprend des moyens d'enregistrement d'une information indiquant si le bac a été déplacé jusqu'à la position de vidage. De préférence, le dispositif de collecte comporte en outre des moyens de traitement de cette information et/ou des moyens de transmission de l'information à un serveur de télécommunication.
  • Le dispositif de collecte est un camion de collecte.
The collection device may further include one or more of the following features.
  • The emptying detection means comprise means for measuring a quantity characteristic of the position of the displacement means or of the tank, such as a sensor. This sensor thus makes it possible to indicate that the moving means, and therefore the tank, take the emptying position of the tank. This position sensor may for example be a sensor indicating the height of the moving means or the tray.
  • The emptying detection means comprise means for measuring the inclination of the waste container or displacement means, for example an angle sensor, these measuring means preferably being integral in displacement with gripping means of the container. of waste. Thus, it can be determined whether the tray has an inclination corresponding to the inclination necessary for complete emptying of the tray, that is to say the inclination of the emptying position. Indeed, for a given collection device and for a given size of waste bin, it is possible to determine a threshold inclination of the tray, sufficient for the waste to empty under the effect of the force of gravity. Thus, if the inclination measured is less than the threshold value, it can be considered that there was no emptying of the waste, and if the inclination is greater than the threshold value, that there has been a.
  • The emptying detection means comprise a contact sensor disposed on a damping bar of the tank in the emptying position.
  • The collection device further comprises means for identifying the waste container, for example radio frequency identification type RFID (Radio Frequency IDentification). The identification of the bin thus makes it possible to associate with a given ferry, or its owner, the information that a dump has taken place or not, with a view to a correct billing of the owner, this information being provided in particular by the means for detecting the emptying. Satisfactory invoicing of the owners of waste bins according to the number of emptying operations makes it possible to encourage citizens to generate less waste.
  • The identification means of the tray include an RFID antenna housed in a housing, and the emptying detection means are housed in the same housing as the RFID antenna. Thus, a single housing is used to protect the RFID antenna and the detection means. In addition to simplifying the arrangement of the collection device, such a configuration generates few modifications to currently used collection devices already equipped with an RFID antenna. In other words, the function of Dump detection can be implemented at a lower cost on the majority of collection devices.
  • The device comprises means for stoppage of the displacement of the waste container, activated according to the identification provided by the identification means. These stop means are activated for example when the tray received by the collection device does not have an RFID tag, or when the identified bin is part of a "black list", for which it refuses to perform the dump . It is particularly advantageous to have the means for detecting the emptying in this case, because it may happen that the stop means are triggered just before or just after emptying the tray, or they do not trigger at all when the stop signal was not received by the collection device or when it is malfunctioning. Thus, the fact that the stop means have been activated does not necessarily mean that the tray has not been emptied, and it is therefore interesting, for a more reliable billing, to determine whether the emptying was carried out.
  • The collection device further comprises means for measuring the weight of the waste container before emptying. The measurement of the weight of the bin allows the owner of the bin to be billed according to the quantity of waste that is in the tanks and that has actually been emptied. This ensures a more reliable billing of the owner of the tank, since a dump that has not occurred will not be charged, even though a weighing has occurred beforehand. A particular advantage of the coexistence of the weight measuring means and the emptying detection means lies in the fact that, if one of these two means is defective, which can happen in a relatively dirty environment such as the collection of waste. waste, particularly with regard to the means of measuring the weight of which the cells are fragile and frequently damaged, relevant information remains to be used for the billing of the tank owner, either the weight of the waste weighed or the information according to which a dump has been made.
  • The collection device comprises warning means activated when a tray has not been moved to its emptying position. These warning means can take different forms, sound, visual, so that the manipulators of the waste container can see that a dump has not been performed or so to perform the emptying operation again.
  • The device comprises means for recording information indicating whether the tray has been moved to the emptying position. Preferably, the collection device further comprises means for processing this information and / or means for transmitting the information to a telecommunication server.
  • The collection device is a collection truck.

L'invention a également pour objet un procédé de vidage d'un bac de déchets dans un dispositif de collecte, comprenant les étrapes suivantes :

  • réception du bac par le dispositif de collecte,
  • déplacement du bac par le dispositif de collecte,
  • enregistrement d'une information indiquant si le bac a été déplacé jusqu'à la position de vidage.
The invention also relates to a method of emptying a waste container in a collection device, comprising the following calipers:
  • receiving the bin by the collection device,
  • moving the tray by the collection device,
  • recording information indicating whether the tray has been moved to the dump position.

L'information enregistrée est de préférence précédée d'une étape de mesure, pendant le déplacement du bac, de l'inclinaison ou d'une autre grandeur caractéristique de la position du bac. Cette étape de mesure peut être effectuée une seule fois ou bien être renouvelée plusieurs fois au cours du déplacement du bac.The recorded information is preferably preceded by a measuring step, during the movement of the tray, the inclination or another characteristic quantity of the tray position. This measurement step can be performed once or be repeated several times during the movement of the tray.

  • la figure 2 est une vue schématique illustrant notamment des moyens de détection du vidage.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings in which:
  • the figure 1 is a schematic side view of the rear of a collection device and a waste container in receiving position (in solid lines) and in emptying position (in broken lines), and
  • the figure 2 is a schematic view illustrating in particular drain detection means.

Comme on peut le voir sur la figure 1, un dispositif de collecte 10, à savoir un camion de collecte, permet de déplacer un bac de déchets 12 qui lui est présenté entre une position de réception (en traits pleins) et une position de vidage (en traits interrompus), au cours de laquelle le bac 12 est incliné de façon que les déchets du bac tombent dans une benne de collecte 14, sous l'effet de la gravité.As can be seen on the figure 1 , a collection device 10, namely a collection truck, makes it possible to move a waste container 12 which is presented to it between a receiving position (in solid lines) and a dump position (in broken lines), during which tray 12 is inclined so that the trash waste fall into a collection bin 14, under the effect of gravity.

Le bac de déchets 12 est un bac monté sur roulettes, muni d'un couvercle 16, monté pivotant par rapport à une cuve 18, de telle façon que le couvercle 16 s'entrouvre pour laisser passer les déchets lorsque le bac 12 est dans la position de vidage illustrée sur la figure 1.The waste container 12 is a tray mounted on wheels, provided with a lid 16, pivotally mounted relative to a tank 18, so that the lid 16 opens to let the waste when the tray 12 is in the emptying position shown on the figure 1 .

Le dispositif de collecte 10 comporte des moyens 20 de déplacement du bac 12 entre la position de réception et la position de vidage. Ces moyens de déplacement 20 comprennent un bras de levage 22, 24, 26, comprenant un support 22 fixé sur le camion 10 et configuré pour se déplacer verticalement, une biellette 24 pouvant pivoter autour de deux axes horizontaux situés à ses extrémités, l'un de ces axes 28 étant porté par le support 22, le bras de levage comportant en outre un préhenseur 26 articulé sur la biellette 24 autour de son autre axe 30. Le préhenseur 26 comprend, dans sa partie supérieure, des moyens de préhension 32, pouvant prendre la forme d'un peigne 32 destiné à s'engager sous une collerette 36 du bac 12 afin de soulever le bac 12, et dans sa partie inférieure, des moyens d'appui 34, destinés à servir de surface d'appui au bas du bac 12. Le camion de collecte 10 comporte des moyens de contrôle du déplacement du bras de levage 22, 24, 26. Le camion 10 comporte également des moyens 38 d'amortissement du bac 12, prenant la forme d'une barre 38 d'amortissement fixée pivotante selon un axe horizontal en partie arrière haute du camion 10 au dessus de l'ouverture de la benne 14, destinée à empêcher que le bac 12 bascule dans la benne lorsqu'il est au sommet de sa course montante.The collection device 10 comprises means 20 for moving the tray 12 between the receiving position and the emptying position. These displacement means 20 comprise a lifting arm 22, 24, 26, comprising a support 22 fixed on the truck 10 and configured to move vertically, a link 24 pivotable about two horizontal axes located at its ends, one of these pins 28 being carried by the support 22, the lifting arm further comprising a gripper 26 hinged to the link 24 about its other axis 30. The gripper 26 comprises, in its upper part, gripping means 32, which can take the form of a comb 32 intended to engage under a flange 36 of the tray 12 to lift the tray 12, and in its lower part, support means 34, intended to serve as a bearing surface at the bottom of the tray 12. The collection truck 10 comprises means for controlling the displacement of the lifting arm 22, 24, 26. The truck 10 also comprises means 38 for damping the tray 12, taking the form of a bar 38. fixed damping pivoting along a horizontal axis in the upper rear portion of the truck 10 above the opening of the bucket 14, intended to prevent the tray 12 tilts in the bucket when it is at the top of its rising stroke.

Le dispositif 10 comporte également des moyens 40 de détection du vidage, représentés sur la figure 2, capables de détecter que le bac 12 a été déplacé jusqu'à la position de vidage. Ces moyens de détection 40 sont logés dans un boîtier 42, disposé au voisinage immédiat des moyens de préhension 32. Dans cet exemple, les moyens de détection du vidage 40 comprennent des moyens de mesure d'une grandeur caractéristique de la position des moyens de déplacement 22, 24, 26. Plus précisément, les moyens 40 comprennent des moyens de l'inclinaison α (alpha) du bac 12, à savoir un capteur d'angle 40. Ces moyens de mesure sont solidaires en déplacement avec les moyens 32 de préhension du bac de déchets, de telle sorte que l'inclinaison α mesurée par le capteur d'angle 40 corresponde à l'inclinaison que prend le bac 12 par rapport au dispositif de collecte 10.The device 10 also comprises means 40 for detecting the emptying, represented on the figure 2 , able to detect that the tray 12 has been moved to the emptying position. These detection means 40 are housed in a housing 42 disposed in the immediate vicinity of the gripping means 32. In this example, the emptying detection means 40 comprise means for measuring a quantity characteristic of the position of the moving means. 22, 24, 26. More specifically, the means 40 comprise means of the inclination α (alpha) of the tray 12, namely an angle sensor 40. These measuring means are integral in displacement with the gripping means 32 waste bin, so that the inclination α measured by the angle sensor 40 corresponds to the inclination that the tray 12 has with respect to the collection device 10.

Le dispositif de collecte 10 comporte en outre des moyens d'identification du bac de déchets 12, de préférence d'identification par RFID. Ces moyens comprennent une antenne 44, capable d'interagir avec une étiquette RFID 46 aménagée sur le bac 12. Cette antenne 44 comprend une bobine intégrée dans un matériau époxy et est logée, dans cet exemple, dans le même boîtier 42 que celui dans lequel est logé le capteur d'angle 40. L'antenne 44 est reliée à des moyens de traitement 50, capables par exemple de traiter les informations émises et/ou reçues par l'antenne 44 et de communiquer avec un ordinateur embarqué sur la camion, cet ordinateur communiquant lui-même avec un serveur de télécommunication utilisé pour la gestion des collectes de déchets, notamment pour leur facturation.The collection device 10 further comprises identification means of the waste container 12, preferably identification by RFID. These means comprise an antenna 44, capable of interacting with an RFID tag 46 fitted on the tray 12. This antenna 44 comprises a coil integrated in an epoxy material and is housed, in this example, in the same housing 42 as that in which is housed the angle sensor 40. The antenna 44 is connected to processing means 50, capable for example of processing the information transmitted and / or received by the antenna 44 and communicate with a computer on board the truck, this computer communicating itself with a telecommunication server used for the management of waste collection, including billing.

On notera que les moyens de traitement 50 ne sont pas forcément logés dans le boîtier 42, ils peuvent être agencés dans une autre partie du dispositif de collecte, voire dans un terminal de télécommunication distant.Note that the processing means 50 are not necessarily housed in the housing 42, they can be arranged in another part of the collection device or in a remote telecommunication terminal.

Le capteur d'angle 40 est, dans cet exemple, relié aux moyens de traitement 50, qu'ils soient ou non logés dans le boîtier 42. Bien sûr, les moyens de traitement des informations fournies par le capteur d'angle 40 pourraient être distincts des moyens de traitements des informations fournies par l'antenne 44. Les moyens de traitement 50 comprennent des moyens d'enregistrement de façon à enregistrer certains ou tous les angles mesurés, ou toute autre information permettant de déduire que le bac a été déplacé jusqu'à la position de vidage. Le capteur d'angle 40 est configuré ici de telle sorte que si un angle mesuré dépasse une valeur seuil, une information correspondante est stockée dans les moyens de traitement 50.The angle sensor 40 is, in this example, connected to the processing means 50, whether or not housed in the housing 42. Of course, the information processing means provided by the angle sensor 40 could be different from the means for processing the information provided by the antenna 44. The processing means 50 comprise recording means so as to record some or all the measured angles, or any other information making it possible to deduce that the tank has been moved to the dump position. The angle sensor 40 is configured here so that if a measured angle exceeds a threshold value, corresponding information is stored in the processing means 50.

Le dispositif 10 comporte également des moyens de stoppage du déplacement du bac 12, en fonction de l'identification fournie par les moyens d'identification 44, tels que décrits plus haut, ainsi que des moyens de mesure du poids du bac de déchets avant et éventuellement après son vidage, tels que décrits plus haut également.The device 10 also comprises means for stopping the movement of the tray 12, according to the identification provided by the identification means 44, as described above, as well as means for measuring the weight of the front hopper and possibly after emptying, as described above also.

Le dispositif 10 peut comporter également des moyens d'avertissement, activés lorsque le bac n'a pas été déplacé jusqu'à sa position de vidage, par exemple un signal sonore ou lumineux permettant d'alerter les manipulateurs du bac.The device 10 may also include warning means, activated when the tray has not been moved to its emptying position, for example a sound or light signal to alert the manipulators of the tray.

Les moyens de stoppage et/ou de mesure du poids et/ou d'avertissement peuvent éventuellement être reliés aux moyens de traitement 50, de façon à être commandés par les moyens 50 et/ou fournir des informations aux moyens 50.The means for stopping and / or measuring the weight and / or warning may optionally be connected to the processing means 50, so as to be controlled by the means 50 and / or to provide information to the means 50.

Le fonctionnement du camion de collecte 10 va à présent être décrit.The operation of the collection truck 10 will now be described.

Le procédé de vidage d'un bac de déchets présenté devant le camion 10 comprend une première étape de réception du bac par le camion, au cours de laquelle le peigne 32 est engagé sous la collerette 36 et au cours de laquelle le bac est identifié, par interaction entre l'antenne 44 et l'étiquette 46, suivie d'une étape de déplacement du bac grâce au bras de levage 22, 24, 26. Simultanément au déplacement, et/ou peu après le déplacement, le procédé comprend une étape d'enregistrement d'une information indiquant si le bac a été déplacé jusqu'à la position de vidage. Plus précisément dans cet exemple, le capteur d'angle 40 mesure l'inclinaison du bac 12, et lorsque cette inclinaison est supérieure à la valeur seuil pour laquelle est configuré le capteur, l'information est enregistrée pour être traitée par la suite. Après le vidage, le bac prend à nouveau sa position de réception.The emptying process of a waste container presented in front of the truck 10 comprises a first step of receiving the container by the truck, during which the comb 32 is engaged under the collar 36 and during which the container is identified, by interaction between the antenna 44 and the tag 46, followed by a step of moving the tray by the lifting arm 22, 24, 26. Simultaneously with the displacement, and / or shortly after the displacement, the method comprises a step recording information indicating whether the tray has been moved to the dump position. More specifically in this example, the angle sensor 40 measures the inclination of the tray 12, and when this inclination is greater than the threshold value for which the sensor is configured, the information is recorded for processing thereafter. After emptying, the bin returns to its receiving position.

Lorsque le camion 10 comporte les moyens de stoppage du déplacement du bac 12, le procédé de vidage peut comporter une étape de stoppage du déplacement, activée après l'identification (ou la non identification) du bac. Cette étape de stoppage est suivie d'une étape d'enregistrement de l'angle exact, fourni par le capteur 40, auquel le bras de levage a été stoppé. Cette information peut être stockée dans les moyens 50 et être traitée par la suite.When the truck 10 includes the means for stopping the movement of the tray 12, the emptying process may comprise a step of stopping the movement, activated after the identification (or non-identification) of the tray. This stoppage step is followed by a step of recording the exact angle, provided by the sensor 40, at which the lift arm was stopped. This information can be stored in the means 50 and be processed thereafter.

Dans le cas où le camion comporte des moyens de mesure du poids des déchets, l'étape de réception du bac par le camion est suivie d'une étape de pesée du bac plein, et d'enregistrement du poids. Puis le vidage est mis en oeuvre, incluant une ou plusieurs étapes de mesure de l'inclinaison du bac. Après le vidage, une seconde étape de pesée du bac, permettant de connaître le poids du bac vide, pour déduire des deux pesées le poids des déchets seuls.In the case where the truck has means for measuring the weight of the waste, the step of receiving the bin by the truck is followed by a step of weighing the full bin, and recording the weight. Then the emptying is implemented, including one or more steps of measuring the inclination of the tray. After emptying, a second weighing step of the tank, allowing to know the weight of the empty tank, to deduce from the two weighings the weight of the waste alone.

On notera que l'invention n'est pas limitée aux modes de réalisation précédemment décrits.Note that the invention is not limited to the previously described embodiments.

Par exemple, les moyens de détection de vidage peuvent prendre d'autres formes que celles d'un capteur d'angle, ils peuvent comprendre un capteur mesurant une grandeur caractéristique de la position du bac ou du bras de levage 22, 24, 26, ou encore un capteur de contact, par exemple disposé sur la barre d'amortissement 38 du camion 10.For example, the emptying detection means may take other forms than those of an angle sensor, they may comprise a sensor measuring a quantity characteristic of the position of the tray or of the lifting arm 22, 24, 26, or a contact sensor, for example disposed on the damping bar 38 of the truck 10.

Parmi les avantages du dispositif de collecte disposé ci-dessus, on notera que les moyens de détection du vidage sont facilement incorporables à des dispositifs de collecte actuellement utilisés, quel que soit leur agencement. En particulier, le cas où les moyens de détection du vidage sont logés dans un même boîtier que celui d'une antenne RFID est particulièrement facile à mettre en oeuvre sur tout type d'antenne déjà connue dans le marché de la collecte des déchets : aussi bien dans une antenne disposée sur un peigne que dans une antenne pour la lecture de puces disposée sur des bacs de collecte de déchets, à préhension frontale ou latérale, ainsi que sur des antennes « bâton » rapportées derrière le peigne d'un bras de levage ou encore une antenne plate ou en bloc utilisée dans le système de levage ou sur tout autre type d'antenne. Aussi, les moyens de détection du vidage peuvent être utilisés dans tout dispositif de collecte dans lequel le bac de déchets subit un mouvement de renversement.Among the advantages of the collection device disposed above, it will be noted that the means for detecting the emptying are easily incorporated into currently used collection devices, whatever their arrangement. In particular, the case where the emptying detection means are housed in the same housing as that of an RFID antenna is particularly easy to implement on any type of antenna already known in the waste collection market: also good in an antenna arranged on a comb in an antenna for reading chips arranged on waste collection bins, front or side gripping, and on "stick" antennas reported behind the comb of a lifting arm or a flat or bulk antenna used in the hoisting system or any other type of antenna. Also, the emptying detection means can be used in any collection device in which the waste container undergoes a reversal movement.

On notera que le capteur d'angle 40 peut être porté par un même support que celui de l'antenne 44 des moyens d'identification, ou bien faire partie d'un boîtier à part et transmettre l'information à un système de traitement disposé sur le camion de collecte ou à distance.It will be noted that the angle sensor 40 may be carried by the same support as that of the antenna 44 of the identification means, or else be part of a separate housing and transmit the information to a treatment system arranged on the collection truck or remotely.
