Abstract

PURPOSE: To bond rubber elements without leaving air causing bonding deficiency in a bonded part after vulcanization. CONSTITUTION: Respective rubber elements A having unvulcanized rubbers A applied to the leading ends thereof are respectively clamped by first and second clamp parts 10, 20 to oppose the leading ends of the rubber elements each other. Next, the second clamp part 20 is moved toward the first clamp part 10 by a moving mechanism 30 to mutually bond the rubber elements A under pressure. Thereafter, the leading end parts of the rubber elements A are covered with a mold parts 40 and pressed under heating in the mold part 40 to vulcanize the unvulcanized rubbers A of the rubber elements A to bond the respective rubber elements A. At this time, since the rubber elements A are mutually bonded under pressure by the pressing force of the moving mechanism 30 in the state clamped by the clamp parts 10, 20, air is excluded from the gap between the unvulcanized rubbers A' by this pressure bonding and air causing bonding deficiency is not left in the bonded part after vulcanization.

Description of the Related Art Conventionally, for example, a rubber gasket used for tunnel construction has an extremely large size because it is formed in an annular shape having substantially the same diameter as the tunnel. Therefore, this gasket is manufactured by joining a plurality of divided members to each other. Specifically, after vulcanizing a rubber body to form each member, the unvulcanized rubber is applied to the joint portion of each member. The joints of the respective members are covered with a dedicated mold to apply pressure and heat to join the respective members.

不良を生じ、その結果、接合部分の強度を低下させるな
ど、品質に悪影響を及ぼすという問題点があった。By the way, in order to apply unvulcanized rubber to the joint portion of each member, an unvulcanized rubber sheet or the like is interposed between each member, or each member is vulcanized. At this time, a method is used in which only the joint is left unvulcanized.However, since these unvulcanized rubbers cannot be completely adhered to each other, air remains at the joint after vulcanization, resulting in poor bonding. As a result, there is a problem in that the quality of the joint is adversely affected, for example, the strength of the joint portion is reduced.

The moving mechanism moves at least one of the clamp portions to the other clamp portion side, and the joint portions of the rubber bodies are pressed against each other. After that, the joint portion of each rubber body is covered with the mold portion, and this is pressurized and heated in the mold portion to vulcanize the unvulcanized rubber of each rubber body, whereby the rubber bodies are joined. At this time, since the rubber bodies are pressed against each other by the pressing force of the moving mechanism while being clamped by the clamps, air is removed from between the unvulcanized rubbers by this pressing, and the joints after vulcanization are removed. No air remains in the.

の原因となる空気が残留することはない。Next, a method of joining rubber bodies using the rubber body joining apparatus will be described with reference to FIG. First, Fig. 5 (a)
As shown in FIG. 5, the rubber bodies A each having an unvulcanized rubber A ′ at its tip (joint) are sandwiched between the first clamp portion 10 and the second clamp portion 20, and the tips are opposed to each other. Next, as shown in FIG. 5B, the moving mechanism 30 moves the second clamp portion 20 to the first clamp portion 10 side, and the tips of the rubber bodies A are pressed against each other. Thereafter, as shown in FIG. 5 (c), the tip of each rubber body A is covered with a mold portion 40, and this is pressed and heated by the mold portion 40 to remove the unvulcanized rubber A'of each rubber body A. Each rubber body A is joined by vulcanizing. At that time, each rubber body A is attached to each clamp 1
Since they are sandwiched by 0 and 20, they are pressed against each other by the pressing force of the moving mechanism 30, so that air is removed from between the unvulcanized rubbers A ′ by this pressing, and the cause of the bonding failure at the bonded portion after vulcanization. There is no residual air.

Since this is done, the air that causes poor joining does not remain in the joined portion after vulcanization, and each rubber body A can always be joined well. Further, since each rubber body A is mechanically held, it is possible to surely prevent displacement and distortion.
