POWDER GRANULE MATERIAL MASS INSPECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a powder granule material mass inspection device capable of detecting the mass of the powder granule material at right timing during the continuous scattering to a scattering object that constitutes the product. ! SOLUTION: In a manufacturing process of a product, a powder granule material mass inspection method includes: an imaging processing process for imaging a powder granule material freely falling toward a scattering object so as to be stored as image data; a concentration determination processing process of the image data; a binarization processing process for binarizing the image data on the basis of a predetermined threshold value when a concentration is equal to or higher than a constant reference concentration; a mass calculation processing process for calculating a mass value of the powder granule material inside binarized image data on the basis of a calibration curve, and a mass determination processing process for determining a total mass of the powder granu
