Optical granular sorting machine

Abstract

The invention discloses an optical particulate material sorting machine. The optical particulate material sorting machine comprises a transfer unit, a particulate material inspection unit, a distinguishing unit as well as an eliminating unit, wherein the transfer unit is at least used for transferring qualified products, defective products and particulate materials containing foreign materials while continuously flowing; the particulate material inspection unit is at least used for simultaneously inspecting the qualified products, the defective products and the particulate materials containing the foreign materials which are transferred while continuously flow and, and the distinguishing unit is at least used for distinguishing whether the particulate materials are separation objects according to the inspection result obtained by the particulate material inspection unit and different color information of the inspected particulate materials; the eliminating unit is at least used for simultaneously eliminating the distinguished separation objects during continuous flow according to distinguishing information obtained by the distinguishing unit. The optical particulate material sorting machine provided by the invention sets a threshold value by effectively utilizing triple element color spatial information of RGB (red, green, blue) which is close to the visions of human beings to, and the judgment and a technology of an operator are not needed.

Description

technical field [0001] The present invention is aimed at granular materials such as grains such as rice and wheat or resin granules. When sorting out good products and defective products, the foreign matter mixed in the granular materials is blown away and removed by the method of blowing air. Material selection machine. Background technique [0002] For a long time, before the sorting operation starts, the operator sets the standard threshold value set in the optical detection means to perform any change operation in the ascending direction or descending direction, (what kind of The foreign matter (glass, stone, etc.) will be regarded as the object of selection and removal from the selected other objects, or the particles of what color (defective grains, defective rice, grains, etc.) For the purpose of adjusting the objects of sorting and removal.) Through such an adjustment operation, the optimum sensitivity can be set, and defective products such as foreign matter and co...

AI Technical Summary

Problems solved by technology

[0006] However, according to the color sorting machine described in the above-mentioned Patent Document 1, the screen of granular objects can be displayed on the operation panel, and the operator can adjust the sensitivity while observing the display, but to what extent? Separation and removal of foreign matter, or the extent to which colored particles are selected and removed, requires the operator to have a certain amount of knowledge such as judgment and technology.
