Description

  The present invention relates to a tire inspection apparatus that inspects a tire while rotating it.

  Normally, a tire is formed by laminating members such as an inner liner, carcass, belt, and tread on a molding drum to form an unvulcanized tire, which is inserted into the mold and expanded and deformed by shaping using a bladder. The tire is then vulcanized by heating while pressing against the molding surface.

  In the manufactured tire, an abnormality may occur in the tire shape or the like due to variations in members being manufactured or variations in the vulcanization molding process. Since such a tire is likely to have poor stability and durability, the tire may be inspected while rotating the tire around the rotation axis before shipping (for example, see Patent Documents 1 and 2 below).

  In the tire inspection apparatus disclosed in Patent Documents 1 and 2, a chuck mechanism provided so as to be able to expand and contract in the tire radial direction is inserted into the hollow portion of the tire from above to hold the bead portion. Then, the tire is carried into an inspection section for inspecting the tire, or the tire is unloaded from the inspection section. In such an inspection apparatus, it is necessary to perform inspection by reducing the diameter of the chuck mechanism after carrying the tire into the inspection portion and then pulling it out from the hollow portion of the tire and retracting it to a position where the chuck mechanism does not interfere with the inspection. . Further, after completion of the inspection, it is necessary to expand the diameter after inserting the chuck mechanism into the hollow portion of the tire, hold the tire on the chuck mechanism, and then carry out the tire from the inspection portion. Therefore, there is a problem that it takes time to carry (carrying in and out) the tire, and it is difficult to shorten the cycle time necessary for inspecting one tire.
