摘要:
The invention relates to a process and an apparatus for sorting reusable pieces of raw material (5), which are continuously moved in a conveying direction (2) by a transporting device (1), wherein an analysis of the chemical composition of the pieces of raw material (5) is performed with the aid of laser-induced plasma spectroscopy (LIBS) and, dependent on the composition determined, an automated sorting of the pieces of raw material (5) is carried out, wherein in a first step the pieces of raw material (5) are subjected to multiple first laser pulses (6), in order to remove surface coatings and/or contaminants from the pieces of raw material (5), and in a second step one or more second laser pulses (7) are directed onto the locations of the pieces of raw material (5) from which the surface coatings and/or contaminants have been removed, wherein exposed material of the pieces of raw material (5) is transformed into a plasma by the second laser pulses (7), wherein the same laser (3) is used for the first and second laser pulses (6, 7) and the area of the pieces of raw material (5) over which the first laser pulses (6) are moved and which are freed of surface coatings and/or contaminants is greater than the area of the pieces of raw material (5) that is exposed to the second laser pulses (7), wherein the focal diameter and the focal point of the laser beam are kept constant between the first and second laser pulses (6, 7). In this way, an unfalsified analysis of the composition of the pieces of raw material (5) can be achieved by using only one laser and, dependent on the analysis, a sorting can be performed.

摘要:
There is provided a method for identifying and sorting randomly distributed waste containers (1) containing different types of refuse sorted at source, wherein the identification is based on an image analysis of a pattern (2) arranged on each container (1). The method for identifying and sorting comprises the following steps: capturing at least one image of each container (1), analyzing the image by determining following characteristics: a shade and/or color of the pattern; a type of the pattern arranged on the container; calculating a sorting value based on the determined characteristics; comparing the calculated sorting value to a predetermined limit value or predetermined range of sorting values in order to classify the type of refuse contained in the container for sorting thereof.
摘要:
The machine with artificial vision for automatic separation by colour of recyclable plastic, with multispectral vision, which uses the ultraviolet, visible and infrared zones of the spectrum simultaneously, at wavelengths of less than 400nm, between 400 and 700nm, and greater than 700nm., obtaining for each piece of plastic analysed its spectrogram, which is specific to each type of plastic. The machine as a whole is made up of a conveyer belt (1) for the plastics to be analysed, a line module (2) where the multispectral lighting and vision systems are located for image intake, an electronic control module with tactile screen (5) where processing cards are located, a computer system that carries out the multispectral analysis of the pieces of plastic and an electronic interface for controlling the expulsion electrovalves (4), a blowing system (3), and material conveyer belts (7) for extracting the main flow and the separated components.

A method for recycling comprises a pulverization step (S1) of pulverizing thermoplastic resin molded articles, each having a different softening point in a resin substrate and having a metal part and a coating film, a metal-material selection-removal step ( S3 ) of selecting and removing a metal material from pulverized pieces, a pulverized resin-material selection step ( S5 ) of selecting a target pulverized resin material for recycling by allowing the pulverized pieces from which the pulverized metal material has been removed to drop and by ejecting gas toward either one of the target pulverized resin material and a non-target pulverized resin material for changing a drop direction thereof, and a coating-film peeling step ( S7 ) of peeling the coating film from the resin substrate by applying a shearing force to the target pulverized resin material under the softening point of the resin substrate of the target pulverized resin material for recycling.
