    Machine with artificial vision intended for automatic separation of black plastic waste by chemical composition
    OBJECT OF THE INVENTION
    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.
    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.
    BACKGROUND OF THE INVENTION
    One of the techniques for waste separation in waste treatment plants is through the chemical composition of the materials where multispectral technology is used.
    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.
    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 the rates of recycling in the treatment of urban solid waste in an environmentally sustainable way, the applicant is the holder of Spanish patent No. ES 2442971 which refers to a system for the treatment of urban 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.
    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.

    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.
    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 when detecting a spectogram obtained by the multispectral vision system of plastic solid waste with a wavelength in the range between 2000 and 7000nm, it is sent a signal to the blowing system that separates such waste from the belt conveys Dora 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.
    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.
    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 power supply, in which it is generated a flow of biogas. In particular, the treatment plant includes a machine with artificial vision as described above.
    When the expression “by chemical composition” is mentioned, the fact that black materials are not only discriminated by color but also 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.
    Other features and advantages of the system object of the present invention will be apparent from the description of a preferred but not exclusive embodiment, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT
    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 No. ES 2442971 published on February 14, 2014, thus improving the efficiency in recycling of materials in a treatment plant as well as the energy efficiency of the plant, as explained in detail in the aforementioned patent.
    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.
    Thus, in this preferred embodiment, the blowing system, schematically represented and generally indicated by reference (7), is located at the end of the conveyor belt (2), including pneumatic solenoid valves connected to an air reservoir. pressurized (8), although one skilled in the art may use another type of suitable blowing system known in the art.
    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).
    Therefore, the treatment of the black plastic waste of the machine is as follows (see Figure 2):
    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. Depending on the chemical composition analyzed, in a third stage (30) the control unit discriminates the black plastic detected by its formula and chemical composition, such that in a fourth stage (40), the residue is blown to the belt corresponding additional conveyor only for the type of black plastics that is currently separated and previously selected by means of a
