Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] Such as figure 1 As shown, the present invention provides a large-size material removal process based on color sorting technology, which specifically includes the following steps:

[0027] Step S1, using the CCD sensor to scan the background reference of the color sorter to obtain the scanned image signal of the background reference as the background signal; wherein, the background reference adopts a monochrome background plate.

[0028] Step S2, extracting...

Abstract

The invention discloses a large-size material removing process based on color sorting technology. A reference value of a background signal is obtained by scanning a color sorter background plate, allscanned image signals obtained by scanning to-be-screened material and the background signal are subjected to contrastive analysis, background signals are removed, material signals are reserved, thenwhether the material signals are from material needing to be removed is judged, and a driving signal is sent to drive a removing mechanism to remove the material according to size of the material needing to be removed. Simple, convenient, efficient and fast effects are achieved, the problems that in the prior art, the size of large material is large, the bad material area being marked with characteristics is small, and the whole material cannot be blown out during blowing are solved, and the color sorting effect is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of color sorting technology, and relates to a material removal technology, in particular to a large-size material removal technology based on a color sorter. Background technique [0002] The color sorter is a device that uses photoelectric detection technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. The color sorter is mainly composed of feeding system, optical detection system, signal processing system and separation execution system. Color sorters can be divided into traditional photoelectric technology color sorters, CCD technology color sorters, infrared technology color sorters and X-ray technology color sorters. [0003] At present, when the color sorter is color-sorting large materials, due to the large size of the large materials, and the area of ​​the bad materials that can be marke...
