DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for molding a tire bead composite structure, and more particularly, to a method for easily molding a bead assembly while maintaining a predetermined shape. The present invention relates to a method and an apparatus for forming a tire bead composite structure capable of supplying a separator and automatically taking out a bead assembly while the bead assembly is held by the separator.

[0002]

2. Description of the Related Art Conventionally, a separator made of a resin or the like has been used as a measure for maintaining the shape and preventing adhesion of a tire bead composite structure constituted by a filler alone or a flipper and a band-shaped reinforcing member. It is common to insert the bead assemblies between the bead assemblies automatically or manually after they have been formed.

[0003]

However, since the tire bead composite structure composed of the filler alone or the flipper and the belt-like reinforcing member is in an unvulcanized state, it is difficult to maintain the shape, and the tire bead composite structure is not easily removed during molding. If the tire bead composite structure is stored in the separator with its tip deformed, there is a problem in terms of quality. There was a problem that would occur.

The present invention has been devised in view of such a conventional problem. When a tire bead composite structure is formed, the tire bead composite structure is vertically formed by being formed with a separator as a back. An object of the present invention is to provide a method and apparatus for forming a tire bead composite structure that can be maintained and stored in a close shape, and that can automatically take out the supplied and molded tire bead composite structure together with the separator. It is.

From this state, as shown in FIG. 19, the two cylinders 27a and 27b operate simultaneously, and the entire pusher ring 26 (the pusher device) moves forward. Further, the cylinders 82 of the plurality of bead demagnetization rings 81 and the cylinders 83 of the bead suction rings 80 attached to the pusher ring 26 are simultaneously operated to exceed the separation allowance H (space) where the bead lock drum 4 advances and retreats. Forming process Z
The bead assembly Wx on the bead lock drum 4 is magnetically transferred by the bead suction ring 80 with the bead lock drum 4 reduced in diameter.

Next, as shown in FIG. 20, when the cylinder 83 of the bead suction ring 80 is contracted, the magnetically transferred bead assembly Wx is transferred to the bead lock segment provided at the end of the bladder drum 21. Stand by on 90. Thereafter, the diameter of the bead lock segment 90 is expanded,
When the bead assembly Wx is firmly gripped from the inside and the cylinder 82 is retracted, a plurality of bead suction rings 80 arranged on the circumference are separated from the bead core portion, and the bead assembly Wx is placed on the bead lock segment 90. It will be completely transferred.

After the operation is confirmed, the two cylinders 27a and 27b are simultaneously moved backward while returning the cylinder 83, and the entire pusher ring 26 is moved backward to the position shown in FIG. Next, in the separator supply device 70,
The bead lock stand 75 enters the position of T1 with the empty separator S mounted at the position of T2 in FIG. The bead lock stand 75 equipped with the separator S
When the home position 1 is reached, the cylinder 76 operates,
The bead lock stand 75 on which the separator S is mounted is moved in the direction of the arrow by about 10 to 15 mm, and is tightly engaged with the bladder drum 21 of the reinforcing band-shaped member sticking and forming apparatus 60.

Thereafter, as shown in FIG.
8 is expanded, and while being pushed by the pusher ring 26, the reinforcing band-shaped member R wound on the bladder drum 21 is attached to the side surface of the finned filler F of the bead assembly Wx to complete the bead finished product Wz. Bead finished product W
After the completion of z, the pusher ring 26 is retracted by the cylinder 27b to the position shown in FIG. 21. At the same time, the bead lock drum 4 returns the cylinder 76 to the original position to take out the finished bead Wz. After the separation, it is moved at a high speed to the position of T3.

At the position T3, as shown in FIGS. 23 and 24, the take-out hand 78a of the suction take-out device 78 takes out the separator S with the finished bead Wz attached thereto.
It is loaded alternately on a predetermined separator carriage 79. Since the arm shaft of the suction and extraction device 78 also has a separator mounting hand 78b, preparation is made to mount the separator S at the position T2 of the bead lock stand 75. When the take-out of the finished bead Wz is completed, the bead lock stand 75 moves to the position T2, attaches the empty separator S, and thereafter repeats the above operation to efficiently assemble the finished tire bead composite. It can be taken out well.

The above operations are performed continuously without any manual operation, whereby each step can be automatically performed without performing a molding operation by separating each step, thereby significantly improving workability and productivity. It is something that can be done.

[0039]

As described above, according to the present invention, the tire bead composite structure can be maintained and stored in a nearly vertical shape by forming the tire bead composite structure with the separator as a backing when forming the tire bead composite structure. Since the reinforcing band-like member is attached to the side surface of the bead and formed, the finished bead can be held without deformation, and the separator is supplied and the formed tire bead composite structure is automatically and efficiently taken out together with the separator. There is an effect that can be. In addition, the work of inserting the bead core and the work of taking out the formed bead assembly are facilitated, and there is an effect that workability and productivity can be significantly improved.
