Title:
生タイヤの異物付着判別方法
Document Type and Number:
Japanese Patent JP6743492
Kind Code:
B2
Abstract:
To reliably and efficiently make foreign matters adhered onto a green tire formed by a strip winding method. It comprises a raw data acquiring step Sa in which raw three-dimensional data D0 about an examination surface 3 are created through rotation of a green tire T and through irradiation with sensor light 2L in an X direction by a two-dimensional displacement sensor 2; an averaging processing step Sb in which processed three-dimensional data D1 are obtained by averaging processing the raw three-dimensional data D0; and an imaging step Sc in which the distance data z in the processed three-dimensional data D1 are each binarized, and an image is created from the binarized processed three-dimensional data D2. The widths wx and wy of a range K of the averaging process are set to be greater than a spiral pitch P of a rubber strip G and less than a width Gw of the rubber strip G.
