Máquina con visión artificial prevista para la separación automática de residuos de plástico de color negro por composición química Machine with artificial vision intended for automatic separation of black plastic waste by chemical composition
MEMORIA DESCRIPTIVA DESCRIPTIVE MEMORY
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente solicitud tiene por objeto el registro de una máquina con visión artificial prevista para la separación automática de residuos de plástico de color negro por composición química para la separación de residuos que incorpora notables innovaciones y ventajas. The purpose of this application is to register a machine with artificial vision intended for automatic separation of black plastic waste by chemical composition for waste separation that incorporates notable innovations and advantages.
Más concretamente, la invención propone el desarrollo de una máquina para el tratamiento de residuos que es capaz de detectar y separar los materiales plásticos negros por composición química del resto de materiales plásticos para su reutilización posterior en aplicaciones de la industria del automóvil, por ejemplo, y una planta para el tratamiento de residuos urbanos provista con dicha máquina. More specifically, the invention proposes the development of a machine for the treatment of waste that is capable of detecting and separating black plastic materials by chemical composition from the rest of plastic materials for later reuse in automotive industry applications, for example, and a plant for the treatment of urban waste provided with said machine.
ANTECEDENTES DE LA INVENCIÓN Una de las técnicas para la separación de residuos en plantas de tratamiento de residuos es a través de la composición química de los materiales donde se utiliza la tecnología multiespectral. BACKGROUND OF THE INVENTION One of the techniques for the separation of waste in waste treatment plants is through the chemical composition of the materials where multispectral technology is used.
Los plásticos comprenden una estructura molecular a base de carbono con enlaces de carbono-carbono simples, dobles, triples y con grupos funcionales, tales como por ejemplo, aldehidos, cetonas, amidas, aminas, alcoholes, ácidos, nitrilos, etc. Estos enlaces tienen una absorción de luz característica a determinadas longitudes de onda. Plastics comprise a carbon-based molecular structure with single, double, triple carbon-carbon bonds and with functional groups, such as, for example, aldehydes, ketones, amides, amines, alcohols, acids, nitriles, etc. These links have a characteristic light absorption at certain wavelengths.
En un diagrama bidimensional, en el que el eje de abcisas representa longitudes de onda y el eje de ordenadas intensidades de luz reflejada por el objeto que se está analizando, cada tipo de enlace nos da un punto del espectrograma, con lo que al obtener todos los puntos en el rango de análisis de longitudes de onda, lo que se obtiene de hecho es una representación gráfica de la composición química del material objeto del análisis.
El rango de análisis va desde el ultravioleta con longitudes de onda inferiores a 400nm, zona visible del espectro 400-700nm e infrarrojo con longitud de onda superior a 700Nm. De esta manera, es posible separar los distintos materiales a reciclar. Para mejorar los índices de reciclaje en el tratamiento de los residuos sólidos urbanos de una forma sostenible desde un punto de vista medioambiental, el solicitante es titular de la patente española ne ES 2442971 que hace referencia a un sistema para el tratamiento de residuos sólidos urbanos basado en la tecnología de visión espectral. Por otro lado, es bien sabido la extensa utilización de plásticos negros/oscuros en la industria automovilística para la fabricación de distintas partes de un vehículo. In a two-dimensional diagram, in which the axis of abscissa represents wavelengths and the axis of orderly intensities of light reflected by the object being analyzed, each type of link gives us a point of the spectrogram, which, when obtaining all the points in the wavelength analysis range, what is obtained in fact is a graphic representation of the chemical composition of the material under analysis. The analysis range goes from the ultraviolet with wavelengths less than 400nm, visible area of the 400-700nm spectrum and infrared with wavelengths greater than 700Nm. In this way, it is possible to separate the different materials to be recycled. To improve recycling rates in the treatment of municipal solid waste in a sustainable way from an environmental point of view, the applicant holds Spanish patent n and ES 2442971 which refers to a system for treating municipal solid waste based on spectral vision technology. On the other hand, the extensive use of black / dark plastics in the automobile industry for the manufacture of different parts of a vehicle is well known.
Sin embargo, la separación de plásticos de color negro respecto al resto de plásticos, incluso entre los propios plásticos de color negro (que pueden tener distinta estructural molecular), es un problema que aún no está resuelto. Al no haber una separación de los mismos por composición química, no es posible su reciclaje y, en consecuencia, no es posible la obtención de materia prima en forma de pellets con el fin de fabricar nuevos plásticos. DESCRIPCIÓN DE LA INVENCIÓN However, the separation of black plastics from the rest of plastics, even among the black plastics themselves (which may have different molecular structures), is a problem that is not yet solved. Since there is no separation of them by chemical composition, recycling is not possible and, consequently, it is not possible to obtain raw material in the form of pellets in order to manufacture new plastics. DESCRIPTION OF THE INVENTION
La presente invención se ha desarrollado con el fin de proporcionar una máquina que se configura como una novedad dentro del campo de aplicación y resuelve los inconvenientes anteriormente mencionados, aportando, además, otras ventajas adicionales que serán evidentes a partir de la descripción que se acompaña a continuación. The present invention has been developed in order to provide a machine that is configured as a novelty within the field of application and resolves the aforementioned drawbacks, also providing other additional advantages that will be apparent from the description that accompanies continuation.
Es por lo tanto un objeto de la presente invención proporcionar una máquina con visión artificial prevista para la separación automática de residuos de plástico de color negro por composición química, que comprende una cinta transportadora para el transporte de los plásticos a separar, un sistema de visión multiespectral para la toma de imágenes de cada uno de los plásticos presentes en la cinta transportadora, estando el sistema de visión multiespectral conectado mediante una unidad de control con un sistema de soplado para la extracción de los plásticos, y se caracteriza esencialmente por el hecho de que el sistema de visión multiespectral emplea una longitud de onda comprendida entre 2000 y 7000nm, tal
que al detectar un espectograma obtenido por el sistema de visión multiespectral de residuo sólido plástico con una longitud de onda comprendida en el rango entre 2000 y 7000nm, se envía una señal al sistema de soplado que separa tal residuo de la cinta transportadora. Con ello se pueden distinguir y separar para reciclar diferentes residuos de plásticos negros de distinta naturaleza, tales como por ejemplo, ABS, PP, PS, PE, PC, etc. It is therefore an object of the present invention to provide a machine with artificial vision intended for the automatic separation of black plastic waste by chemical composition, comprising a conveyor belt for transporting the plastics to be separated, a vision system multispectral for the taking of images of each of the plastics present in the conveyor belt, the multispectral vision system being connected by a control unit with a blowing system for the extraction of plastics, and is essentially characterized by the fact of that the multispectral vision system employs a wavelength between 2000 and 7000nm, such that upon detecting a spectrogram obtained by the multispectral vision system of plastic solid waste with a wavelength in the range between 2000 and 7000nm, a signal is sent to the blowing system that separates such residue from the conveyor belt. This can be distinguished and separated to recycle different residues of black plastics of different nature, such as, for example, ABS, PP, PS, PE, PC, etc.
De esta manera, es posible separar los plásticos negros entre sí por composición química del resto de plásticos de una forma eficiente, lo que aumenta el índice de reciclaje con respecto a otros sistemas de gestión o tratamiento de residuos de la técnica conocidos. In this way, it is possible to separate the black plastics from one another by chemical composition from the rest of the plastics in an efficient manner, which increases the recycling rate with respect to other known waste management or treatment systems of the art.
Es también otro objeto de la invención proporcionar una planta para el tratamiento de residuos urbanos, que comprende unos medios para la separación automática de un primer grupo de materiales reciclables del tipo de material plástico reciclable, y un segundo grupo de materiales reciclables del tipo de cartón, papel o similar, basados en la tecnología multiespectral, y unos medios para procesar una cantidad de fracción de materia orgánica presente en los residuos urbanos a tratar mediante un proceso de fermentación anaerobica alimentados eléctricamente por medios de suministro de corriente, en el que se genera un flujo de biogás. En particular, la planta de tratamiento incluye una máquina con visión artificial como la descrita anteriormente. It is also another object of the invention to provide a plant for the treatment of urban waste, which comprises means for the automatic separation of a first group of recyclable materials of the type of recyclable plastic material, and a second group of recyclable materials of the cardboard type , paper or similar, based on multispectral technology, and means for processing an amount of organic matter fraction present in urban waste to be treated by an anaerobic fermentation process electrically fed by means of current supply, in which it is generated a flow of biogas. In particular, the treatment plant includes a machine with artificial vision as described above.
Cuando se menciona la expresión "por composición química" el hecho de que los materiales negros no son solamente discriminados por el color sino por su propia estructura o composición química. De este modo, se obtiene una planta que no solamente es más eficiente sino que además permite separar los plásticos negros del resto de plásticos, favoreciendo más la función de separación y reciclaje de residuos. When the expression "by chemical composition" is mentioned the fact that black materials are not only discriminated by color but by their own chemical structure or composition. In this way, a plant is obtained that is not only more efficient but also allows the separation of black plastics from other plastics, favoring the function of separation and recycling of waste.

A la vista de las mencionadas figuras y, de acuerdo con la numeración adoptada, se puede observar en ellas un ejemplo de realización preferente de la invención, la cual comprende las partes y elementos que se indican y describen en detalle a continuación. Así, tal como se aprecia la máquina con visión artificial, indicada de forma general con la referencia (1 ), prevista para la separación automática de residuos de plástico de color negro, comprende una cinta transportadora (2) para el transporte de los plásticos a separar dispuesta sobre una estructura de apoyo (3), un sistema de visión multiespectral para la toma de imágenes de cada uno de los plásticos presentes en la cinta transportadora. Tal máquina puede estar montada en una planta automatizada para el tratamiento de residuos urbanos como se describe en la solicitud de patente española del mismo titular ne ES 2442971 publicada en fecha 14 de febrero de 2014, por lo que mejora la eficiencia en el reciclaje de materiales en una planta de tratamiento así como la eficiencia energética de la planta, tal como se explica con detalle en la patente anteriormente mencionada. In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below. Thus, as the machine with artificial vision can be seen, indicated in general with reference (1), intended for the automatic separation of black plastic waste, it comprises a conveyor belt (2) for transporting plastics to separate arranged on a support structure (3), a multispectral vision system for taking images of each of the plastics present in the conveyor belt. Such a machine can be mounted in an automated plant for the treatment of urban waste as described in the Spanish patent application of the same owner n e ES 2442971 published on February 14, 2014, thus improving the efficiency in the recycling of materials in a treatment plant as well as the energy efficiency of the plant, as explained in detail in the aforementioned patent.
El sistema de visión multiespectral presenta diversas cámaras (4) (representadas de forma esquematizada) que se encuentran alojadas en una estructura de soporte (5) vinculada con la cinta transportadora (2), las cuales están conectadas a través de una unidad o módulo de control (6) provisto en la máquina con un sistema de soplado para la extracción de los plásticos. The multispectral vision system has several cameras (4) (represented schematically) that are housed in a support structure (5) linked to the conveyor belt (2), which are connected through a unit or module control (6) provided in the machine with a blowing system for the extraction of plastics.
De esta manera, en esta realización preferida el sistema de soplado, representado de forma esquematizada e indicada de forma general con la referencia (7) está ubicado al final de la cinta transportadora (2), incluyendo unas electroválvulas neumáticas conectadas a un
depósito de aire presurizado (8), si bien un experto en la materia podrá emplear otro tipo de sistema de soplado adecuado conocido en la técnica. Thus, in this preferred embodiment, the blowing system, represented schematically and indicated in general with reference (7), is located at the end of the conveyor belt (2), including pneumatic solenoid valves connected to a pressurized air reservoir (8), although one skilled in the art may employ another type of suitable blowing system known in the art.
Ventajosamente, el sistema de visión multiespectral anteriormente citado emplea una longitud de onda comprendida entre 2000 y 7000nm, tal que al detectar un espectograma obtenido por el sistema de visión multiespectral de residuo sólido plástico con una longitud de onda comprendida en el rango entre 2000 y 7000nm, se envía una señal a la unidad de control de funcionamiento de la máquina que posteriormente envía una señal de salida al sistema de soplado que separa tal residuo de la cinta transportadora hacia un depósito o un sistema de almacenamiento y/o tratamiento de tales residuos que incluye diversas cintas transportadoras adicionales (9). Advantageously, the aforementioned multispectral vision system employs a wavelength between 2000 and 7000nm, such that when detecting a spectrogram obtained by the multispectral vision system of plastic solid waste with a wavelength in the range between 2000 and 7000nm , a signal is sent to the machine operation control unit that subsequently sends an output signal to the blowing system that separates such waste from the conveyor belt to a tank or a storage and / or treatment system of such waste that includes various additional conveyor belts (9).
Por lo tanto, el tratamiento de los residuos de plástico negro de la máquina es el siguiente (véase la figura 2): Therefore, the treatment of the black plastic waste of the machine is as follows (see Figure 2):
En una primera etapa (10) los plásticos son transportados por la cinta transportadora en el sentido indicado con las flechas en la figura 1 , los cuales pasan por el punto donde están situadas las cámaras del sistema de visión multiespectral, donde se realiza en una segunda etapa (20) el espectrograma. En función de la composición química analizada, en una tercera etapa (30) la unidad de control discrimina el plástico de color negro detectado por su fórmula y composición química, tal que en una cuarta etapa (40), el residuo es soplado a la cinta transportadora adicional correspondiente solamente para el tipo de plásticos negros que está separado en este momento y que previamente se ha seleccionado mediante una pantalla táctil (1 1 ) presente en la máquina, que está en comunicación con la unidad o módulo de control (6). In a first stage (10) the plastics are transported by the conveyor belt in the direction indicated with the arrows in Figure 1, which pass through the point where the cameras of the multispectral vision system are located, where it is performed in a second stage (20) the spectrogram.
