Description

Crack relay type intelligent track color selector

Technical Field

The invention belongs to the technical field of color sorters, and particularly relates to a seam relay type intelligent crawler color sorter.

Background

The color sorter is a Device for automatically sorting out the heterochromatic particles in the particle materials by utilizing a photoelectric detection technology according to the difference of the optical characteristics of the materials, namely when a CCD (charge coupled Device) sensor (CCD, English full name: charged coupled Device) detects the heterochromatic particles, an air jet valve or an air gun blows away the heterochromatic particles through air blowing, and therefore the screening of the particle materials with different colors is realized.

As shown in fig. 1, the conventional color sorter with dual-view image acquisition needs to throw out a material from a belt 1', and acquire images from the upper and lower surfaces of the material at the front end of the belt 1' for identification, analysis and calculation. In order to improve the color selection precision, an intelligent deep learning algorithm is applied, so that the longer the time required for scanning and imaging materials by a camera is, the longer the time required for the camera to transmit acquired signals to an industrial personal computer for processing, and the processing time and the time for scanning and acquiring images can cause a blowing nozzle 2 'for removing the materials to be far away from a viewpoint 3' (the position for capturing the materials by the camera).

Along with the development of the color sorter, sorted materials are more and more in variety, and the sorted materials comprise common small particles and flaky materials and also comprise special-shaped large materials such as long peppers and wooden knives and forks. Because the material is large, the nozzle for removing the blowing nozzle needs to be far away from the viewpoint. After the materials are thrown out by the horizontal conveying belt at a high speed, due to light weight or strange shape, the throwing tracks are more disordered and inconsistent as the materials are thrown out farther, and the net selection rate and the carrying-out ratio of the materials are not ideal.
