Filler connection part inspection method
First Claim
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:
- attaching an annular assembled unit, which is configured by the bead core and the filler that is adhered along the outer circumference of the bead core, to an outer circumference of a support ring supported by a base;
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, wherein the step of obtaining data, the step of repeating, and the step of comparing are performed on two side surfaces of the filler.

Abstract
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.
