Abstract

The sorter consists of a scanner (1) which reads bar codes on the containers and recognises their colours. The scanner is linked to an index recording the colours of all containers of domestic liquid products in everyday use and the type of plastic from which it is made. The containers are fed to a vertical conveyors with scoops (2) which tip them onto horizontal belt conveyors (3) according to their type. The horizontal conveyors drop the containers into different bins (4).

Description

La présente innovation concerne une machine pour trier les déchets plastiques ménagers de type corps creux rigides, c'est à dire les emballages pour liquides, qui se trouvent dans des conteneurs suite à l'apport volontaire. La finalité est de faciliter le recyclage de ces déchets en fonction de leur matière et de leur couleur, grâce à l'identification de ces deux paramètres. The present innovation relates to a machine for sorting household plastic waste of the rigid hollow body type, that is to say the packaging for liquids, which are in containers following voluntary contribution. The aim is to facilitate the recycling of this waste according to its material and color, by identifying these two parameters.

Le tri de ces déchets plastiques s'effectue d'ordinaire manuellement ou encore à l'aide de moyens techniques telle la fluorescence X ou la spectroscopie infrarouge ou les caméras CCD ou bien encore la combinaison de ces techniques. Ces moyens techniques élargissent sensiblement la capacité de tri mais rencontrent quelques obstacles. Lorsque les déchets plastiques contiennent encore quelque peu le produit qu'ils conditionnaient, il s'en suit une altération de l'analyse des rayons X ou infrarouges, car ces technologies sont basées sur les propriétés des matiéres. The sorting of this plastic waste is usually carried out manually or using technical means such as X-ray fluorescence or infrared spectroscopy or CCD cameras or even the combination of these techniques. These technical means significantly increase sorting capacity but encounter some obstacles. When the plastic waste still contains somewhat the product that they were conditioning, there follows an alteration of the analysis of X-rays or infrared, because these technologies are based on the properties of the materials.

La nouveauté selon la présente machine réside dans le fait d'être peu limitée dans la diversité des matières et des couleurs à trier, et par conséquent d'être aussi pointue que possible. Le tri ne s'effectue pas sur la base des propriétés des matières mais sur l'identification d'un signe présent sur les déchets plastiques. Il s'agit d'associer les moyens conventionnels de traitement informatique du code à barres avec une chaîne mécanique. En effet les déchets plastiques présents dans les conteneurs de collecte sont relativement propres et possèdent encore l'étiquette sur laquelle figure le code à barres. Ce code est spécifique, propre à un seul produit du commerce. Par conséquent, en associant une matière et/ou une couleur à ce code unique il est possible d'utiliser cette information pour effectuer le tri. The novelty according to the present machine resides in the fact of being little limited in the diversity of materials and colors to be sorted, and consequently of being as sharp as possible. Sorting is not done on the basis of the properties of the materials but on the identification of a sign present on plastic waste. This involves associating conventional means of computer processing of the bar code with a mechanical chain. In fact, the plastic waste present in the collection containers is relatively clean and still has the label on which the barcode appears. This code is specific, specific to a single commercial product. Consequently, by associating a material and / or a color with this unique code, it is possible to use this information to perform the sorting.

Un scanner (1) pour le décodage relié à un fichier informatique où sont enregistrées les matières et les couleurs de chaque emballage plastique connu sur le marché, lit le code à barres. Cet équipement détermine la destination, c'est à dire le bac de récupération vers lequel est à déposé l'emballage plastique identifié. Nombre d'emballages répondant aux mêmes paramètres de sélection tout en ayant un code à barres différent, sont déposés dans un seul et même bac de récupération. En fait des familles sont constituées dans le fichier informatique en fonction de la matière et de la couleur; chaque famille étant composée de un à plusieurs codes à barres. A scanner (1) for decoding linked to a computer file where the materials and colors of each plastic packaging known on the market are recorded, reads the bar code. This equipment determines the destination, that is to say the recovery bin to which the identified plastic packaging is deposited. A number of packages that meet the same selection parameters while having a different barcode are deposited in one and the same recycling bin. In fact families are formed in the computer file according to the material and the color; each family being composed of one to several bar codes.

L'utilisation habituelle du code à barres est, entre autres, I'affichage sur un écran du produit et de son prix ainsi que l'impression d'un ticket de caisse. Dans le cas présent, les mêmes éléments électroniques et informatiques servent à commander des moteurs et des électro-aimants afin d'orienter les déchets plastiques à destination de bacs de récupération. The usual use of the barcode is, among other things, the display on a screen of the product and its price as well as the printing of a sales receipt. In the present case, the same electronic and computer elements are used to control motors and electromagnets in order to direct the plastic waste destined for recovery bins.

Les déchets plastiques sont chargés sur la chaîne de tri après la lecture du code à barres. Cette chaîne de tri est composée de godets (2) qui se déversent sur des tapis (3) entraînant les déchets plastiques vers les bacs de récupération (4). Ces bacs ne peuvent recevoir qu'une seule famille de déchets plastiques à laquelle ils sont associés par la gestion informatique du code à barres. Le déversement des godets sur le "bon" tapis est effectif par le biais d'un registre à décalage. Un moteur donne le mouvement à la chaîne de tri à raison d'un pas (comme c est le cas pour un ticket de caisse enregistreuse) et des électro-aimants articulent les godets (il s'agit d'un ordre similaire à l'impression d'un ticket de caisse) pour qu'ils se déversent sur les tapis. Plastic waste is loaded onto the sorting chain after reading the barcode. This sorting chain is made up of buckets (2) which flow onto carpets (3) carrying plastic waste to the recovery bins (4). These bins can only receive a single family of plastic waste to which they are associated by the computerized management of the barcode. The dumping of the buckets on the "right" belt is effective through a shift register. A motor gives movement to the sorting chain at the rate of one step (as is the case for a cash register receipt) and electromagnets articulate the buckets (this is an order similar to the printing a receipt) so that they spill on the carpets.

Cette nouvelle machine de tri des déchets plastiques ménagers de type corps creux rigides est destinée à l'industrie du recyclage ainsi qu'aux municipalités qui organisent la collecte de ces déchets par apport volontaire.  This new sorting machine for household plastic waste of the rigid hollow body type is intended for the recycling industry as well as for municipalities which organize the collection of this waste by voluntary contribution.
