BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting a vulcanized tire from a tire vulcanizer to a post-cure inflator.

[0002]

2. Description of the Related Art Generally, a vulcanized tire vulcanized and molded in a vulcanization molding section of a tire vulcanizer is taken out from the vulcanization molding section, conveyed to an expansion cooling section of a post cure inflator, and expanded and cooled. After that, it is taken out from the expansion cooling unit and carried out. At this time, in the post-cure inflator, expansion cooling requires a longer time than vulcanization molding.Therefore, in order to improve the productivity of the tire vulcanizer by eliminating the waiting time of vulcanization molding by expansion cooling, Two or more expansion cooling units are provided for the vulcanization molding unit.

Therefore, conventionally, the method of transporting the vulcanized tire from the tire vulcanizer to the delivery via the post-cure inflator is to rotate the two expansion cooling sections 104, 104 as shown in FIG. 4, for example. A turnover type post cure inflator 103, which is provided as possible, is arranged in a post process of the tire vulcanizer 100, and a roller conveyor 105 is provided below the post cure inflator 103.
Is arranged and the expansion cooling units 104, 104 are rotated to hold the vulcanized tire taken out from the vulcanization molding unit 101 in the expansion cooling units 104, 104 at a predetermined position. The vulcanized tire whose expansion and cooling have been completed is transferred from the expansion and cooling section 104 to the roller conveyor 105 and carried out.

[0004]

However, in the above-described conventional method for conveying a vulcanized tire, the vulcanized tire is expanded and cooled in the post-cure inflator 103.
4, the expansion / cooling unit 104 is rotated, so that the gap between the tire vulcanizer 100 and the post-cure inflator 103 is closed by the expansion / cooling unit 1.
It is necessary to set the distance larger than the turning radius of 04.104, which causes a problem that the size of the entire apparatus is increased.

Further, when the vulcanized tire is held in the expansion cooling units 104, 104, the expansion cooling units 104, 104
It is necessary to perform an operation of rotating the vulcanized tire to stop at a predetermined position and an operation of transporting the vulcanized tire from the vulcanization molding unit 101 to the predetermined position. Therefore, since the positioning accuracy is likely to decrease due to the two operations, there is a problem that the expansion cooling units 104 may not be able to hold the vulcanized tire.
Particularly, the operation of rotating the expansion cooling units 104, 104 to stop at a predetermined position is a major factor that lowers the positioning accuracy because the center of rotation of the expansion cooling units 104, 104 changes depending on the presence or absence of vulcanized tires. Has become.

Further, since it is necessary to provide the post-cure inflator 103 with a mechanism for rotating the expansion / cooling unit 104 and a mechanism for transferring it to the roller conveyor 105, the post-cure inflator 103 becomes complicated and large. There is also the problem of doing.

Therefore, the present invention enables the post cure inflator 103 to be simplified and downsized, and
Conveying vulcanized tires that enable the expansion and cooling unit 104 to hold the vulcanized tires with high reliability and further reduce the size of the entire device including the tire vulcanizer 100 and the post-cure inflator 103. It is intended to provide a method.

[0008]

In order to solve the above-mentioned problems, a method of transporting a vulcanized tire includes a vulcanization molded by a vulcanization molding section of a tire vulcanizer for vulcanizing a green tire. A step of taking out the vulcanized tire from the vulcanization molding part, a step of transporting and holding the vulcanized tire to a plurality of fixed expansion cooling parts of the post cure inflator, and a step of expanding and cooling the expansion cooling part. And removing the sulfurized tire from the expansion cooling section.

[0009]

According to the above construction, the vulcanized tire is conveyed to and held by the plurality of fixed expansion cooling sections of the post cure inflator, so that the expansion cooling section is rotated and held. Compared with the case, the gap between the tire vulcanizer and the post cure inflator can be set to a smaller distance, and as a result, the entire device can be downsized.

Further, since the vulcanized tire is conveyed and held in the expansion / cooling section by only one operation of moving the vulcanized tire, which can be easily positioned, the positioning accuracy is improved and the expansion is improved. It is possible to improve reliability when the cooling unit holds the vulcanized tire. Furthermore, since it is not necessary to provide a mechanism for rotating the expansion cooling unit in the post cure inflator, the post cure inflator can be simplified and downsized. Further, since a mechanism for transferring the vulcanized tire, which has been expansion-cooled, from the expansion-cooling unit to the unloading device unit such as the roller conveyor is not necessary, the post-cure inflator can be simplified and downsized. There is.
