Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component replacement method in a tire vulcanizer and a replacement device thereof, and more particularly, a bladder central mechanism as a component and a component replacement method capable of easily replacing a vulcanization container device. And an exchange device thereof.

  As a conventional tire vulcanizing apparatus 1, for example, as shown in FIG. 6, a bladder center mechanism 16 that can be raised and lowered is provided at the center of a sector mold 6 that is divided into a plurality (8 to 12) in the circumferential direction. The mainstream was the one integrated with the vulcanizer.

  However, since the sector mold 6 and the tire vulcanizing apparatus 1 are integrated, there is a problem that the apparatus is complicated, the entire apparatus is enlarged, and a wider space is required. Further, each sector mold 6 is configured to move up and down together with the upper side plate 2 and move in the horizontal direction, so that the airtightness at the joint portion of each sector mold 6 and the load from the circumferential direction are overloaded. There is a problem that it is difficult to improve tire uniformity and tire productivity cannot be improved in order to perform tire setting and vulcanization work with one tire vulcanizer. there were.

  Therefore, in the recent tire vulcanizing apparatus 1, as shown in FIG. 7, as shown in FIG. There are provided molds 4 and 5 and a sector mold 6 which is divided into a plurality in the circumferential direction and which expands and contracts toward the center.

  The sector mold 6 includes a back segment 9 to which each sector piece 8 having the tire profile surface 7 of the molded tire W is detachably attached, and a predetermined inclination angle α formed on the back side of each back segment 9. The sliding contact surface 10 is provided with slidable guide means 11, and this guide means 11 is suspended from a support plate 12 that can be raised and lowered.

  Each said back segment 9 is slidably mounted on the guide rail 13 laid radially toward the center on the lower side plate 3 (see, for example, Patent Document 1).

However, such a tire vulcanizing apparatus 1 is separated from the upper mold 4 provided on the upper side plate 2 in a state where the sector mold 6 and the lower mold 5 are placed on the lower side plate 3. Since it is configured, it is often used at the time of replacement of the bladder center mechanism and at the time of replacement of the vulcanizing container device 15 composed of the upper mold 4, the lower mold 5, the sector mold 6, the upper side plate 2, and the lower side plate 3. It takes a lot of time and effort, and the worker is extremely dangerous when exposed to high temperatures, and there is a problem that the replacement work of the bladder center mechanism and the vulcanizing container device cannot be performed quickly and efficiently. .
