Abstract

本发明涉及一种颗粒物料光学色选机,包括下料料槽、图像采集系统、吹风系统和信息处理与控制系统,所述图像采集系统的观察区域位于下料料槽限定的物料移动轨迹上,所述信息处理和控制系统分别与所述的图像采集系统和吹风系统信号连接,用于根据所述图像采集系统的图像数字信号识别异色颗粒,控制吹风系统进行相应的吹风动作,所述吹风系统设有若干吹嘴,所述各吹嘴的吹风路径穿过所述下料料槽限定的物料移动轨迹,其与物料移动轨迹的相交位置位于所述图像采集系统观察区域的下方,所述图像采集系统优选面阵或线阵CCD成像的CCD相机。该色选机的处理量大,结构简单,对异色颗粒的判断准确,可自动去除物料中的异色颗粒,主要用于大米等颗粒物料的分选。
The invention relates to a grain material optical color selector which comprises a discharge chute, an image collecting system, a blowing system as well as an information treating control system. The observing area of the image collecting system is arranged on a material moving track limited by the discharge chute; the information treating control system is respectively connected with the image collecting system and the blowing system in a signaling way used for identifying the grains with different colors according the image digital signals of the image collecting system and controlling the blowing system to carry out corresponding blowing actions. The blowing system is provided with a plurality of blowing nozzles; the blowing path of each blowing nozzle passes through the material moving track limited by the discharge chute; the crossing position of the blowing paths and the material moving track is arranged below the observing area of the image collecting system. The image collecting system preferentially selects a CCD camera of area array CCD imaging or linear array CCD imaging. The color selector has large treating amount, simple structure and accurate judgment to the grains with different colors, which can automatically remove the grains with different colors in the material and is mainly used for sorting the grain materials, such as rice, etc.
