Abstract: A tire conveying apparatus includes a conveyor for conveying a tire, a position sensor, and a controller for controlling the conveyor. The controller includes a determination unit which determines whether or not the tire is positioned within an allowable area for a reference area set in a conveyance path of the conveyor, based on a detection result of the position sensor, and a center conveyor control unit which drives the conveyor such that the tire is positioned within the allowable area, if a determination that the tire is not positioned within the allowable area is made.

Abstract: A rim exchanger includes a rim stocker. The rim stocker has an upper rim support portion that supports an upper rim, and a lower rim support portion that supports a lower rim. The upper rim support portion and the lower rim support portion have a pair of support arms separated from each other. A portion between an end of one support arm and an end of the other support arm forms an open end where a rim body enters a portion between the pair of support arms. An upper surface of one support arm forms a protrusion portion support surface which supports a protrusion portion of a rim from below.

Abstract: A tire testing apparatus allows attachment and detachment of a rim assembly in which first and second rims are integrated and performs testing of a tire attached to the rim assembly. The tire testing apparatus includes a first attaching part; a second attaching part; a rotating part that rotates the first attaching part around a reference axis orthogonal to the first reference surface of the first rim attached to the first attaching part; a fixing part that fixes the first attaching part and the second attaching part to each other and is capable of releasing the fixation; an attaching portion moving part that adjusts the distance in a direction along the reference axis between the first attaching part and the second attaching part; and a rotation regulating part that regulates rotation of the second attaching part around the reference axis.

Abstract: Provided is a rim exchange apparatus of a tire testing machine having a simple and space-saving configuration and capable of rotating a turntable having a plurality of rim placing parts with no interference and appropriately identifying a plurality of rim assemblies set on the turntable. A turntable is installed to be rotated about a rotary shaft with respect to the support part, a plurality of rim placing parts on which a rim assembly is placed are provided to the turntable about the rotary shaft, and reading parts are attached to the support part at a lower side of the turntable. Then, the reading parts read rim identification information of the rim assembly placed on the rim placing parts through the turntable at a predetermined reading position. Accordingly, the identification information of the rim assembly can be appropriately read with no interference with rotation of the turntable.

Abstract: A rim assembly includes a first rim on which a first reference surface is formed, a second rim on which a second reference surface is formed, a through-hole that extends to intersect the first reference surface of the first rim and into which an inserting part is inserted, pins erected on one of the first and second reference surfaces, protruding portions formed on the other of the first and second reference surfaces, first supporting members provided for the first reference surface, and second supporting members provided for the second reference surface. Groove portions with which the protruding portions are engaged are formed around the outer peripheral surfaces of the pins. The first and second supporting members come into contact with each other when the protruding portions are separated from the groove portions, and are separated from each other when the protruding portions are engaged to the groove portions.
