Abstract

A tire vulcanization bladder assembly is manufactured by placing a first ring part on a base stage installed on leg parts in a periphery of a first end opening of a bladder; sandwiching a first clamp part of the bladder, the bladder being in an upright position with the first clamp part on a lower side and a second clamp part located in a periphery of a second end opening of the bladder on an upper side, by the first ring part, thereby attaching the first ring part to the bladder; inserting an inside ring member of a second ring part into the bladder from above on an inside ring member of the first ring part; moving the inside ring member of the second ring part upward relative to the bladder to a position of the second clamp part; and attaching the second ring part to the second clamp part.

First claim

The invention claimed is:

1. A method of manufacturing a tire vulcanization bladder assembly in which a first ring part including an inside ring member and an outside ring member is attached to a bladder for tire vulcanization by sandwiching a first clamp part formed in a periphery of a first end opening of the bladder with the first ring part, and a second ring part including an inside ring member and an outside ring member is attached to the bladder by sandwiching a second clamp part formed in a periphery of a second end opening of the bladder with the second ring part, the method comprising:
placing the first ring part on a base stage installed on leg parts;
attaching the first ring part to a first clamp part of the bladder, the bladder being in an upright position with the first clamp part on a lower side and a second clamp part on an upper side;
inserting and placing the inside ring member of the second ring part into the bladder from above on the inside ring member of the first ring part;
moving the inside ring member of the second ring part upward relative to the bladder such that it is disposed at a position of the second clamp part; and
attaching the second ring part to the second clamp part.

2. The method of manufacturing a tire vulcanization bladder assembly according to claim 1 , wherein the inside ring member of the second ring part placed on the inside ring member of the first ring part is supported by a support member, and is moved upward relative to the bladder by extending the support member upward.

3. The method of manufacturing a tire vulcanization bladder assembly according to claim 2 , wherein when the inside ring member of the second ring part is supported by the support member, the inside ring member of the second ring part is positioned at a predetermined location of the support member by engaging with a positioning part provided on the support member.

4. The method of manufacturing a tire vulcanization bladder assembly according to claim 2 , wherein when the first ring part is placed on the base stage, the first ring part is positioned at a predetermined position of the base stage by engaging with a positioning part provided on the base stage.

5. The method of manufacturing a tire vulcanization bladder assembly according to claim 3 , wherein when the first ring part is placed on the base stage, the first ring part is positioned at a predetermined position of the base stage by engaging with a positioning part provided on the base stage.

6. The method of manufacturing a tire vulcanization bladder assembly according to claim 1 , wherein the inside ring member of the second ring part placed on the inside ring member of the first ring part is supported by a support member, and is moved upward relative to the bladder by moving the base stage downward while maintaining a position of the support member.

7. The method of manufacturing a tire vulcanization bladder assembly according to claim 6 , wherein when the inside ring member of the second ring part is supported by the support member, the inside ring member of the second ring part is positioned at a predetermined location of the support member by engaging with a positioning part provided on the support member.

8. The method of manufacturing a tire vulcanization bladder assembly according to claim 6 , wherein when the first ring part is placed on the base stage, the first ring part is positioned at a predetermined position of the base stage by engaging with a positioning part provided on the base stage.

9. The method of manufacturing a tire vulcanization bladder assembly according to claim 1 , wherein when the first ring part is placed on the base stage, the first ring part is positioned at a predetermined position of the base stage by engaging with a positioning part provided on the base stage.

10. A manufacturing device for manufacturing a tire vulcanization bladder assembly in which a first clamp part at a periphery of a first end opening of a tire vulcanization bladder is sandwiched by a first ring part that includes an inside ring member and an outside ring member to attach the first ring part to the bladder, and, a second clamp part formed at a periphery of a second end opening of the bladder is sandwiched by a second ring part that includes an inside ring member and an outside ring member to attach the second ring part to the bladder, the manufacturing device comprising:
a base stage installed on leg parts; and
a support member disposed in a central portion of the base stage in plan view; wherein
the base stage and the support member are configured to be capable of moving vertically relative to each other,
the first ring part placed on the base stage is attached to the first clamp part of the bladder, the bladder being in an upright position with the first clamp part on the a lower side and the second clamp part on an upper side,
the inside ring member of the second ring part is placed on the inside ring member of the first ring part and supported by the support member,
the inside ring member of the second ring part is moved upward relative to the bladder to a position of the second clamp part, and
the second ring part is attached to the second clamp part.

11. The manufacturing device for manufacturing a tire vulcanization bladder assembly according to claim 10 , wherein the support member is a structure configured to extend and retract in a vertical direction, and the inside ring member of the second ring part placed on the inside ring member of the first ring part is moved upward relative to the bladder by extending the support member upward.

12. The manufacturing device for manufacturing a tire vulcanization bladder assembly according to claim 11 , wherein a positioning part configured to engage with the inside ring member of the second ring part is provided on the support member such that the inside ring member of the second ring part is positioned and placed at a predetermined position on the support member.

13. The manufacturing device for manufacturing a tire vulcanization bladder assembly according to claim 11 , wherein a positioning part configured to engage with the first ring part is provided on the base stage such that the first ring part is positioned and placed at a predetermined position on the base stage.

14. The manufacturing device for manufacturing a tire vulcanization bladder assembly according to claim 12 , wherein a positioning part configured to engage with the first ring part is provided on the base stage such that the first ring part is positioned and placed at a predetermined position on the base stage.

15. The manufacturing device for manufacturing a tire vulcanization bladder assembly according to claim 10 , wherein the base stage is a structure configured to extend and retract in a vertical direction, and the inside ring member of the second ring part placed on the inside ring member of the first ring part is moved upward relative to the bladder by moving the base stage downward.
