<p>PROBLEM TO BE SOLVED: To detect a container, which is in contact with another container at a part other than a reinforcement part, as a container with defective trunk diameter.SOLUTION: Equipment for inspecting trunk diameter failure of a glass bottle 1 with a reinforcement part 11, of which the strength is reinforced, formed around a circumference of the glass bottle includes: a rotation drive mechanism 2 for rotating the glass bottle 1 around a central axis c thereof; a first trunk diameter detection sensor 3 for detecting a trunk diameter Ralong the entire circumference of a contact part at which a roller contactor 30 is brought into contact with a position of the reinforcement part 11 of a trunk 10 of the glass bottle 1; a second trunk diameter detection sensor 4 for detecting a trunk diameter Ralong the entire circumference of a contact part at which a roller contactor 40 is brought into contact with a position of a non-reinforcement part 13 of a trunk 10 of the glass bottle 1, which is the same angular position as that of the roller contactor 30 of the first trunk diameter detection sensor 3; and a comparison circuit part for outputting a trunk diameter defective signal when a detection output by the second trunk diameter detection sensor 4 is larger than a detection output by the first trunk diameter detection sensor 3 at any angular position.</p> |
