Color sorter

Abstract

The invention provides a color sorter, and belongs to the technical field of color sorters. The color sorter comprises a machine body and multiple side-by-side slide grooves. Each slide groove is correspondingly provided with a first wave band light source and a second wave band light source. Each first wave band light source and the corresponding second wave band light source emit light beams towards the inner portion of the corresponding slide groove so that first wave band reflection light and second wave band reflection light can be formed on the surface of a material. Each slide groove iscorrespondingly provided with a first camera set. Each first camera set is perpendicular to the extension direction of the corresponding slide groove so as to receive a first wave band reflection light signal. A second camera set is arranged at the connection position of every two adjacent slide grooves. Each second camera set is arranged in the direction perpendicular to the extension directionof the corresponding slide groove so as to receive a second wave band reflection light signal. Each first wave band light source and the corresponding second wave band light source are used for emitting light of different wave bands. Each first camera set is arranged at the center position of the width of the corresponding slide groove. Each second camera set is arranged at the connection positionof the two corresponding adjacent slide grooves. According to the color sorter, two types of cameras can all be arranged at optimal view angles, and the material color sorting accuracy rate can be increased.

Description

technical field [0001] The present invention relates to the technical field of color sorting machines, in particular to a color sorting machine. Background technique [0002] With the extensive application of color sorters in the grain and oil industry, China's color sorter industry is becoming more and more mature, with more and more varieties and specifications, from the initial visible light band sorting to the current infrared band sorting, and then to the X-ray band. For sorting and ultraviolet band sorting, different bands need to have their corresponding light sources. [0003] There are many kinds of impurities in materials. In order to identify materials and impurities more accurately, the existing color sorter arranges infrared light sources and visible light sources at the same time at the channel. Correspondingly, there are also corresponding infrared cameras and visible light cameras. When the materials pass through the viewing point, Illuminated by visible lig...

Problems solved by technology

[0004] However, in the prior art, when the material slides to the point of view through the slideway, only one of the infrared camera and the visible light camera can obtain the best material spectral information due to the limitation of the position, so that during the material detection process, the infrared The camera and the visible light camera cannot collect the real signal of the material surface at the same time, which affects the judgment of material color sorting, thereby reducing the accuracy of color sorting
