(57) 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.
