摘要： A split mold for vulcanizing a tire is held at a mold holding section, which is held on a rotatable base, and then a measuring section measures distances to an inner surface of the split mold in the inside diameter direction and in the axial direction. An operating section acquires two-dimensional geometric data of the inner surface of the split mold from the distances measured above, and further acquires geometric data over the entire circumference by rotating the rotatable base, and the data are combined to acquire three-dimensional geometric data of the inner surface of the split mold and make reference geometric data for tire inspection.

摘要： There is disclosed an apparatus in which when a surface having a curved portion, for example, a tire surface is visually inspected, light is uniformly illuminated on the surface. In this apparatus, an image pickup operation is performed by a CCD for a region to be visually inspected, which is illuminated by turning on LEDs. Based on the image pickup result, a density distribution of the region to be visually inspected is prepared. A difference between a target light quantity and light quantity, which is obtained for each field angle of the density distribution at which the region to be visually inspected is illuminated by each light source unit, is calculated and corrected. This correction allows the quantity of light reflected from the region to be visually inspected on the inner peripheral surface to become uniform.

摘要： The present invention discloses a tire chuck apparatus for holding a tire having a tire bead. The apparatus comprises: a gripping mechanism with at least two gripping members movable in tire radial direction from a retracted position to an extended position for pressing against the inner side of the bead portion of the tire, thereby holding the tire; gripping rollers as the gripping members adapted to be rotatable around an axis substantially parallel to a central axis of the tire; and a rotation drive mechanism for rotating the tire around the central axis of the tire. According to this apparatus, even if the center of the tire and the center of the chuck are out of alignment with each other, by rotating the gripping rollers so as to rotate the tire, the tire is shifted so that the center thereof is aligned with the center of the chuck apparatus, thus reducing mispositioning.

摘要： An elastic member 11 positioned between an inner surface of a casing 2 and a front face of a pressure sensing portion 8 of a pressure sensor 1 reduces a possibility of liquid and foreign matters in a tire directly reaching the pressure sensing portion 8. The elastic member also increases adhesiveness between the pressure sensing portion 8 of the pressure sensor 1 and a labyrinth structure and further prevents a potting agent 9b from flowing into the sensing portion 8. Moreover, the elastic member 11 is a member constituting at least a part of the labyrinth structure, so that it does not need that a wall is provided on the pressure sensor 1 and a dedicated seal member is provided on the pressure sensing portion 8.
