Abstract
In a post-cure inflator of the present invention, a rim of a pair of disk shape rims for sandwiching bead portions of a tire has one rim surface and the other rim surface in which a plurality of step portions corresponding to the bead portions of different bead diameters are formed so as to reduce thickness from a center to an outer periphery. A pair of the rims is supported switchably between arrangement in which the one rim surfaces face each other and arrangement in which the other rim surfaces face each other. By such a configuration, it is possible to favorably sandwich the tire even when the bead diameter to be treated is added.
Claims9
A post-cure inflator for performing expansion cooling to a vulcanized tire having bead portions of various bead diameters and bead width, comprising:
- a pair of disk shape rims having rim surfaces for sandwiching the bead portions of the tire on both sides;
- and
- a rim support mechanism for detachably supporting a pair of said rims, wherein
- in the rim of a pair of said rims, a plurality of step portions corresponding to the bead portions of different bead diameters are formed on one rim surface and the other rim surface so as to reduce thickness from a center to an outer periphery, and
- said rim support mechanism supports a pair of said rims switchably between arrangement in which the one rim surfaces face each other and arrangement in which the other rim surfaces face each other.
A rim exchange method of a post-cure inflator for performing expansion cooling to a vulcanized tire having bead portions of various bead diameters and bead width by sandwiching the bead portions with a pair of disk shape rims having rim surfaces on both sides, wherein
- a pair of the rims is formed by two of a rim in which a plurality of step portions corresponding to the bead portions of different bead diameters are respectively formed on one rim surface and the other rim surface so as to reduce thickness from a center to an outer periphery, a pair of the rims being supported switchably between arrangement in which the one rim surfaces face each other and arrangement in which the other rim surfaces face each other, the method comprising:
- detaching one rim attached to a first attachment member and conveying the rim to the exterior;
- guiding the other rim attached to a second attachment member to the first attachment member so as to perform detachment from the second attachment member and attachment to the first attachment member;
- and
- attaching the one rim already conveyed to the exterior to the second attachment member which is empty so as to change the arrangement in which the one rim surfaces face each other to the arrangement in which the other rim surfaces face each other or vice versa.
A rim of a post-cure inflator to be attached to either a first attachment member or a second attachment member provided in the post-cure inflator for performing expansion cooling to a vulcanized tire having bead portions of various bead diameters and bead width and to be formed into a disk shape having rim surfaces abutted to the bead portions on both sides, including one rim surface and the other rim surface in which a plurality of step portions corresponding to the bead portions of different bead diameters are formed so as to reduce thickness from a center to an outer periphery, and having a first engagement portion engaged with the first attachment member and a second engagement portion engaged with the second attachment member.
