Embodiment Construction

[0039] The image of the material collected by the viewing mirror in the related art is an image formed by light diffusely reflected by the light source on the surface of the material; The side light source illuminates the surface of the material.

[0040] Specifically, the first viewpoint 111' is coincident with the second viewpoint 211'.

[0041] For example, if figure 1 As shown, the color sorting device 100' in the related art can generally include: a first color sorting component 10' and a second color sorting component 20', and the first color sorting component 10' and the second color sorting component 20' are symmetrically arranged , the moving direction of the material 500' to be observed is from top to bottom, and the first viewpoint 111' and the second viewpoint 211' are the same point. Taking the first mirror 11' as an example, the illumination range of the second light source 22' corresponding to the second mirror 21' is limited above the first mirror 11', and th...

Abstract

The invention discloses a color sorting device, a color sorting machine and a color sorting method. The color sorting device comprises a first color sorting assembly and a second color sorting assembly, wherein the first color sorting assembly comprises a first sight glass and a first light source; the first sight glass is provided with a first sight point; the first light source is provided witha first illumination range; the second color sorting assembly comprises a second sight glass and a second light source; the second sight glass is provided with a second sight point; the second light source is provided with a second illumination range, wherein the first sight point and the second sight point are spaced in the proceeding direction of to-be-observed material; the first sight point and the first sight glass are positioned out of the second illumination range; and the second sight point and the second sight glass are positioned out of the first illumination range. According to thecolor sorting device, the first sight glass and the second sight glass do not have bright spot or bright surface during imaging and are higher in image definition to reduce the error recognition rate.

Description

technical field [0001] The invention relates to the technical field of sorting granular materials, in particular to a color sorting device, a color sorting machine with the same, and a color sorting method based on the color sorting device. Background technique [0002] Most of the color sorters in the related art adopt the structure of double-view mirrors at the same point of view. Light sources are arranged in the front and rear directions of the material. Improve the recognition rate of the color sorter, especially for materials with different characteristics at different positions. However, this technology will form bright spots and bright surfaces at the viewpoint, which will affect the material recognition of image processing. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the embodiment of the first aspect of the present invention is to ...
