[0003]

In the conventional fully automatic tire vulcanizing press, a high-temperature and high-pressure heating / pressurizing medium is introduced into the tire mold with the tire mold closed, and the tire is compacted. The time for carrying in the unvulcanized tire, molding, and taking out the vulcanized tire is shorter than the vulcanization reaction time for vulcanization, and the mold opening / closing device (for tire loading / unloading etc.) A waiting time occurs in the mold opening / closing device for opening and closing the mold) and the tire loading / unloading device, and the operation rate of the mold opening / closing device and the tire loading / unloading device is poor.

[0004] In order to improve the operation rate, a fully automatic tire vulcanizing press of a mold opening / closing device traveling system in which a mold opening / closing device travels across a plurality of tire molds has been already proposed. Requires a tire mold clamping mechanism that clamps the tire mold from outside the tire mold and closes the tire mold against the pressure of the high-temperature, high-pressure heating and pressurized medium introduced inside the tire. As it becomes expensive.

In addition, in this fully automatic tire vulcanizing press of the mold opening / closing device traveling system, a waiting time is generated in the mold opening / closing device at the time of exchanging a tire mold due to a change in the specification of the vulcanized tire, and there is a danger. There was a problem. In addition, at the time of vulcanization of the tire, the applicant has
We have already proposed a tire mold that cancels the force to open the tire mold inside the tire mold by the pressure of the high-pressure heating and pressurizing medium (steam, steam + inert gas, or hot water) (necessary If the see Japanese Patent Application No. 4-11121 flat specification.). If you use this tire mold,
The tire mold clamping mechanism (the tire mold is closed from the outside of the tire mold by closing the tire mold against the pressure of the high-temperature and high-pressure heating / pressurizing medium introduced into the tire. A mold clamping mechanism) is not required.

The present invention has been made in view of the above problems, and has as its object the operation rate of a mold opening and closing device.

[0008]

The tire vulcanizing equipment of the present invention is constructed as described above, and includes a mold opening / closing device, an empty unloader, and a loader holding an unvulcanized tire at the position of a tire mold during vulcanization. When the vulcanization is completed, the tire mold is opened by the mold opening / closing device, the vulcanized tire is lifted by the unloader, and the vulcanized tire is transferred to a post-processing device such as a gripping / expanding / cooling device for vulcanization. After lifting the finished tire, the unvulcanized tire is suspended by the loader into the tire mold, and then the loader is moved to the unvulcanized tire supply device to retrieve the unvulcanized tire, and the tire opening / closing device is used to release the tire vulcanized tire. The mold is closed, and then the mold opening and closing device is moved to the tire mold position where vulcanization is finished. Furthermore, in the unvulcanized tire supply device, the next vulcanized tire is selected from the storage shelf, transferred to the delivery position together with the pan, and the unvulcanized tire is carried out by the loader, and the empty pan is removed. The tire is transferred from the delivery position to the unvulcanized tire receiving position, and waits. When the unvulcanized tire transported by the monorail hoist or the like is placed on the waiting pan, the unvulcanized tire is transferred together with the pan to an empty position on the storage shelf.
