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:
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.

The present invention includes a sensor malfunction determination unit 207 detects the pressure value corresponding to a signal outputted by a pressure sensor 101 capable of measuring the internal pressure of a pneumatic tire 10. When the detected pressure value is decreasing along the time axis, the sensor malfunction determination unit 207 determines that the pressure sensor 101 is not malfunctioning.

A tire T as a workpiece mounted on a rotary table 2 is imaged by using floodlight means 10 for applying white slit light and a color CCD camera 20 for imaging a portion illuminated by the slit light while it is turned, the coordinates and brightness of the tire T are detected from the obtained image data by coordinate computing means 31 and brightness computing means 33, and the 3-D coordinate data and color image of the tire T are re-formed from the obtained shape data and brightness data of the tire T by shape image forming means 32 and appearance image forming means 34 and compared with tire appearance and shape data prestored in tire information storage means 35 to judge whether the appearance and shape of the tire T are acceptable or not.
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.
