FILLER CONNECTION PART INSPECTION METHOD

摘要

Provided is a filler connection part inspection method by which the connection state of both end surfaces of a belt-shaped filler that has been affixed annularly along the outer periphery of a bead core is inspected. The filler connection part inspection method includes a step of obtaining data of the distance between optical sensors and side surfaces of the filler by scanning, at the side surfaces of the filler, sections of the vicinity of the both end surfaces along the tangential direction of the filler over a predetermined scanning range with the optical sensors, a step of repeating the data obtaining step while the positions of the optical sensors are changed along the radial direction of the filler, and a step of comparing the obtained data with reference data that is set in advance.

1. A filler connected portion inspection method for inspecting a connection state of two end surfaces of a strip of a filler adhered along an outer circumference of a bead core into an annular form, the filler connected portion inspection method comprising the steps of:
obtaining data of a distance from an optical sensor to a side surface of the filler by scanning a portion proximate to the two end surfaces at the side surface of the filler in a tangential direction of the filler over a predetermined scanning range with the optical sensor; repeating the step of obtaining data while changing a position of the optical sensor in a radial direction of the filler; and comparing the obtained data with reference data that is set in advance.
