摘要
The present invention provides a quality control method and a quality control apparatus for use in the formation of a glass product. A feeder mechanism cuts a column-like molten glass pushed out through an orifice thereof into a glass gob and allows each glass gob to fall with gravity from the orifice. A predetermined glass product is formed from the glass gob after delivering the fallen glass gob to a predetermined position. According to the present invention, the glass gob produced by the feeder mechanism is observed by a plurality of optical observing means spaced apart from each other during a falling process of the glass gob, and three-dimensional coordinates data of the entire surface of the glass gob is generated. Measurement data relating to at least one of a volume, a weight, a surface shape, a length, a thickness, an angle in a falling direction, and a cut surface shape of the glass gob is produced based on the three-dimensional coordinates data. The presence or absence of a defect in the quality of the glass gob is detected by comparing the measurement data with quality standard data of a normal glass gob. A causal relationship between at least one of the operational factors of the feeder mechanism and the quality defect is determined depending on the type of quality defect identified. IMAGE
