Definitions

  • the invention relates to the field of waste collection in a context of waste sorting by their producers.
  • a producer refers to any person who produces waste.
  • a producer may be, without limitation, an individual, a group of individuals in a collective dwelling, a company, a group of companies, an administration.
  • bins or collection containers that producers present on public roads to be emptied into a collection truck.
  • producers sort their own waste they use different bins to separate the different types of waste and the collection is carried out in a differentiated manner between bins of each type.
  • specific bins for glass, for paper, cardboard or plastics, for metals, for organic household waste are common to use specific bins for glass, for paper, cardboard or plastics, for metals, for organic household waste.
  • the bins are visually distinguishable, often by their color, sometimes standardized, or by the color of their lid.
  • a collection truck belonging to a particular collection stream empties only the bins likely to contain paper, even if other bins are present on the public road.
  • This verification is necessarily superficial and does not detect inappropriate contents buried in the bins.
  • drums for introducing waste.
  • a drum forms a sort of airlock between the inside and outside of the container and prevents direct access to its interior.
  • volumes limited to the capacity of the drum, which excludes bodies of children, can be introduced into the container.
  • the present invention aims to remedy these drawbacks by proposing a solution for verifying the contents of the bins that provide a more reliable diagnosis as to the contents of the bins.
  • the device can manage the switching authorization (in the case of a marked resemblance between the measurement and a known characteristic profile of desirable content) or the prohibition of switching (in the event of a marked resemblance between the measurement and a profile known unwanted content characteristic or in the absence of resemblance between the measurement and a known characteristic characteristic of desirable content) or both.
  • the invention applies to collection bins used by producers and presented on public roads for emptying in a collection truck.
  • the collection tank is the temporary container and the collection truck is the container of greater capacity.
  • Authorization or prohibition can be automatic, by coupling the tilting device with the device of the invention, or manually, by sending a signal sound or light for people to operate the tilting device.
  • the scanning device proposed above makes it possible to ensure that the sorting of the waste is correctly carried out and that the temporary container does not present any type of waste other than those for which the large capacity container is intended. This verification is particularly useful in cases where the mere presence of one or a few poorly sorted waste in the large capacity container may prevent recycling of all its contents. It can thus be decided to prohibit the tilting of the container rather than introduce a type of unwanted waste into the container. For example, the presence of porcelain in a glass bin generates chunks of porcelain that can prevent the recycling of all pieces of glass, requiring to throw all the container instead of recycling.
  • the presence of glass in a container reserved for the plastic such as PET can prevent or hinder the recycling of the entire container, as well as the presence of concrete, earth or tile in the middle of waste.
  • the physical measurement performed is compared with the pre-recorded profiles so as to identify that the waste contained in the temporary container corresponds mainly or only to a predetermined type, for example glass, plastic , homogeneous paper (not soiled by liquids or organic waste), batteries or textiles.
  • the device is arranged in such a way that the tilting of the temporary container is authorized if the measurement made is close to the pre-recorded profiles, possibly only if the measurement made is close to the pre-recorded profiles.
  • the measurement is very different from the pre-recorded profiles, it means that the contents of the tray has one or more unwanted waste, whatever they are, and we can prohibit the tilting of the container.
  • it is relatively simple to proceed as follows: rather than looking for unwanted waste, it is verified that the waste is in conformity with that which is expected, which avoids providing detection means specific to several types of possible unwanted waste. (For example, using both metal detection means, glass detection means, and liquid detection means).
  • the scanning device comprises a mechanism carrying the measuring means.
  • This mechanism moves the measuring means along the tray when the latter is presented in the gripping position by the tilting device, before or after gripping the tray but before tilting.
  • the scanning device comprises a fixed support for the measurement means, arranged in such a way that a tray starts moving it in order to tilt it past the measuring means.
  • This embodiment has the advantage of taking advantage of the movement of the tank for emptying to take the physical measurement characteristic of its contents. Of course, it is necessary that the measurement is completed before the emptying of the bin in the collection truck has begun, so as to interrupt the tilting movement in case of undesirable content.
  • This embodiment is particularly suitable for tilting devices which start by lifting the tray, substantially by vertical translation, before rotating them around a horizontal axis to empty them.
  • the measuring means cover the entire height of a tray and can take the physical measurement characteristic of the entire contents of the tray without relative movement between the measuring means and the tray.
  • the measuring means can be fixed by a support on the collection truck or separated from the collection truck.
  • the measuring means comprise a portable terminal connected to the container, configured to allow an operator to scan the contents of the tray before it is installed on the collection truck.
  • the scanner can indicate an abnormality in the tray even before we have started to handle the tray.
  • the sensors are metal detectors.
  • the device of the invention can thus remove contents incorporating metal parts such as bottle caps and remove them from a paper or glass collection stream, for example.
  • the sensors are acoustic density sensors.
  • the density of waste makes it possible to distinguish quite clearly between glass, metals, paper, packaging and bottles.
  • the sensors are an X-ray scanner combined with an image analyzer, making it possible to identify contents such as stone, glass, plastic, metals.
  • the sensors are a microwave spectrometer for identifying the presence of fats, diapers or food residues in a paper content.
  • the sensors are a passive radiometric scanner combined with an image analyzer for identifying hidden objects, such as pieces of ceramic pots in a green waste material for composting.
  • the sensors are a gamma ray scanner providing a density measurement, also suitable for detecting garden object residues in composting waste.
  • the device further comprises means for transmitting an acceptance or refusal signal to a computer system.
  • This computer system is generally on board the collection truck, which can also be equipped with a system for identifying the bins, so that the acceptance or rejection signals transmitted by the device of the invention can be associated with a bin ID.
  • Behavioral optimization can result from the exploitation of this information, for example by raising the awareness of producers who are not concerned about the proper filling of their bins, or even by charging the collection.
  • the invention also applies to a voluntary intake container.
  • the drum constitutes the temporary container and the container constitutes the container of greater capacity.
  • An advantageous application of the invention to a voluntary delivery container is to adapt the billing of the collection to the behavior of the waste producer. Indeed, by systematically checking the contents of the temporary container, it can be ensured that the producers using this container have correctly sorted their waste and apply a preferential tariff.
  • the invention relates to a voluntary intake container provided with a scanning device as described above and a producer identification device, for example in the form of a card reader. smart.
  • the invention makes it possible to reward a sorting and supply effort by rewarding the producer who brings the desired type of waste to the container, for example by crediting his account with a sum of money.
  • the verification of the contents of the temporary container then becomes an essential condition for the acceptance of the waste brought by the producer into the container.
  • a collection truck 20 of the type comprising a bucket 22 opening from the rear.
  • the truck is equipped with a tray tilting device 28, provided with lateral protections 24, 26 diagrammatically represented, and two arms.
  • the containers 28 adapted to this tilting device are provided with suitable gripping shapes to coincide with corresponding shapes on the arms.
  • a tray 28 may comprise a reinforced rim, while the arms may comprise a comb which is housed under the rim to lift the tray 28 and tilt in the bucket 22.
  • Other gripping means are known and will not be described here.
  • the bins 28 further comprise a front face 28a, intended to be positioned facing the pickup truck 20 at the time of emptying the tray, the side faces 28b, a rear face 28d and a cover 28c.
  • the tank 28 For its emptying in the collection truck 20, the tank 28 is moved by a operator at the foot of the opening of the bucket 22 and presented at the location and in the appropriate orientation to allow gripping of the tray 28 by the tilting device.
  • the tilting device pours the tray 28, it first undergoes translation upwards, then a rotation to be reversed over the opening of the bucket 22. It then partially penetrates the volume of the skip 22.
  • tipping devices are known, for example that of grasping the tray 28 on the side of the truck 20 and bringing it above the truck 20, to pour it into a bucket 22 whose opening opens towards the high.
  • the present invention is not limited to a particular tilting device and can be easily transposed by those skilled in the art to devices other than that shown in the accompanying drawings.
  • the measuring means 32 may take different forms, already listed. Depending on their nature, they provide a statement of several values or a single value.
  • the database can contain multi-valued profiles, which can be represented graphically, as in the figure, or a single value. In an extremely simplified version, the database is limited to a single value, which defines a threshold below or above which contents of trays 28 can be considered compatible with a collection stream.
  • the comparator uses more or less complex comparison means, depending on the complexity of the measurement taken by the measuring means 32 and pre-recorded profiles.
  • Computer means embedded on the truck 20 perform this operation.
  • FIG. 3 there is shown a first embodiment of the means of measurement 32.
  • These measuring means comprise two screens that operate vis-à-vis, one 44 being for example a two-dimensional network of transmitter / receiver sensors covering the face to be inspected tray and the other 46 just thinking the transmitted signal, filling a simple mirror function.
  • one of the screens would be a two-dimensional network of transmitters and the other would be a two-dimensional array of receivers.
  • the mirror screen 46 which does not require electrical connections because it is passive, is mounted on the tilting device so as to press against the front face 28a of the tray. Since the tray 28 is set in motion, the mirror screen 46 follows its path until it reaches a position in which it is opposite the transmitter / receiver screen 44, but before emptying the tray 28 in At this moment, the signal emitted by the transceiver screen 44 is reflected by the mirror-screen 46 through the tray 28. The contents of the tray 28 are then analyzed and translated into a form. output signal of the transceiver 44. If necessary, the tilting device marks a stop in this position to allow the sensor 32 and the comparator to perform their functions.
  • the comparator then compares this output signal to pre-recorded profiles and provides an enable or prohibit signal to the failover device.
  • the tilting device continues (or resumes if it had marked a stop) its trajectory to empty the tray 28 in the bucket 22.
  • the tilting device performs the reverse maneuver to rest bin 28 on the floor. The contents of the tray 28 are emptied into the collection truck 20 only if it is considered compatible with the collection flow of the truck 20.
