付・成形装置は、公知である。(Prior Art) Conventionally, unvulcanized material is applied to a rotatable forming drum and the outer circumferential surface of the cylindrical outer circumferential surface of the rotating forming drum or the outer circumferential surface of an unvulcanized tire member already wrapped around the outer circumferential surface of the cylindrical cylinder. It is equipped with an unvulcanized tire component supply device (usually called a savisa) that supplies vulcanized tire components, and once the unvulcanized tire component is wrapped around the above-mentioned outer circumferential surface, the forming drum is temporarily stopped. Then, the worker uses a hand tool to visually cut off the excess uncured tire material (if it has already been cut into one circumference, do not do this). Grasp the vicinity of the unwrapped end (hereinafter referred to as the rear end) of the sulfur tire member with your fingers and join it to the front end with a predetermined lap margin, and if necessary, apply hand rolls or stitch rolls to the joint. A winding/forming device for an unvulcanized tire member is known, which completes the winding/forming work of the unvulcanized tire member by performing the following forming operations.

あつた。(Problems to be Solved by the Invention) When an unvulcanized tire member is cut, it shrinks due to its internal stress and becomes shorter in length. The amount of shrinkage at this time differs in the width direction of the unvulcanized tire member due to the composition, temperature, etc. of the unvulcanized tire member. In addition, since there are unvulcanized tire components that cannot be cut, such as ply with steel cord, the worker grasps the rear end of the unvulcanized tire component with his fingers and holds it against the front end with a predetermined lap distance, as described above. Then, if necessary, perform forming operations such as hand rolls or stitch rolls on the joints to wrap and wrap unvulcanized tire parts.
Although the molding work is completed, this work requires skill, which limits the number of workers who can engage in the work, and requires heavy labor. There were also problems with inconsistent quality and lack of productivity.

る。 Next, the operation of the unvulcanized tire member wrapping and forming apparatus shown in FIGS. 1 to 4 will be explained in detail. Sidewall feed roll 31, bead reinforcement member feed roll 33, and pinch roll 34
By stretching the bead reinforcing member 22, the overhang part 26 of the bead reinforcing member 22 is prevented from being wrinkled during subsequent molding with the forming drum 1, and the bead reinforcing member 22 is stretched and the bead reinforcing member 22 is The front end portion 23 of the unvulcanized tire member 2, which has been crimped and bonded to the member 22 by the sidewall feed roll 31 and the crimping/bonding roll 35, is sucked and held by the suction device 4, and transferred to the first conveying device. 3
1 to 35 are waiting. When it is the turn to wrap the unvulcanized tire member 2, the fluid pressure cylinder 53,
53 operates in the extension direction, and the guide rail 52 and suction device 5 descend directly above the suction device 4 (see 5 in Fig. 1).
5), the vicinity of the front end portion 23 of the unvulcanized tire member 2 is attracted and held. At this time, the adsorber 4 releases adsorption. Next, the adsorber 5 moves forward in the direction of the forming drum 1, but at this time, each roll 31, 3
2, 33, and 34 also rotate synchronously to advance the unvulcanized tire member 2 toward the forming drum 1. The suction device 5 passes the front end 23 of the unvulcanized tire member 2 onto the cylindrical outer circumferential surface 11 of the forming drum 1, and the front end 23 of the unvulcanized tire member 2 is adhered to the cylindrical outer circumferential surface 11 of the forming drum 1. When the suction device 5 is released, the suction unit 5 releases the suction and ascends. Next, the forming drum 1 and each roll 31, 32, 33, 34 rotate synchronously, and the unvulcanized tire member 2 is moved onto the forming drum 1 until the front end 23 of the unvulcanized tire member 2 is at the position 24.
The suction device 5 is wound around and temporarily stopped there, during which time the adsorbent 5 returns to the position shown in solid line in FIG. Next, the adsorber 5
is lowered, and the unvulcanized tire member 2 is transferred to the adsorbers 4 and 5.
Once the unvulcanized tire member 2 is attracted and held, the disc knife 6 rotates and moves forward to cut the unvulcanized tire member 2. When this cutting is completed, the adsorption device 5 is moved forward while the forming drum 1 is rotated to wrap the unvulcanized tire member 2 around it. If the winding is completed as is, the unvulcanized tire member 2 will have been cut at the time of the above cutting so that the front end and the rear end of the unvulcanized tire member 2 face each other with a slight gap. . Immediately before the wrapping of the unvulcanized tire member 2 is completed, the forward speed of the adsorber 5 is reduced. On the other hand, since the forming drum 1 continues to rotate at the same speed, the rear end of the unvulcanized tire member 2 is pulled toward the front end, and the front and rear ends are butt-joined. During this time, the overhang portion of the front end is pressed by the presser metal fitting 54, and both ends are aligned. Once the front and rear ends have been butt-jointed,
The suction of the suction device 5 is released, and it rises and returns to the standby position (see 55 in FIG. 1), and the overhang portion 26 of the unvulcanized tire member 2 is pressed against the molding surface by a stitcher (not shown). After being bonded, the wrapping and molding of the unvulcanized tire member 2 is completed.

ある。 Next, the operation of the unvulcanized tire member wrapping and forming apparatus shown in FIG. 6 will be explained in detail. The roller 72 is driven to convey the unvulcanized tire member 2, and when the front end of the unvulcanized tire member 2 is located below the suction device 5, the suction device 5 is lowered and the suction devices 5 and 7 are moved. The front end of the unvulcanized tire member 2 is sucked and held, then the roller 72 is reversed to stretch the unvulcanized tire member 2, and the suction devices 5 and 7 are moved at the same speed toward the forming drum 1. Then, the front end of the unvulcanized tire member 2 is adhered to the cylindrical outer peripheral surface of the forming drum 1,
While raising the suction device 5 and returning it to its original position, the molding drum 1 is rotated, and at the same time, the suction device 7 is moved in synchronization with the rotation of the molding drum 1.
When the front end reaches the 24th position after winding,
The unvulcanized tire member 2 is sucked and held by the suction device 5 and moved toward the forming drum 1. The subsequent operation is similar to that of the apparatus shown in FIGS. 1 to 4 above.

及び作業能率を向上できる効果がある。(Effects of the Invention) The unvulcanized tire member wrapping/forming device of the present invention is configured as described above, and the unvulcanized tire member is conveyed in the direction of the forming drum by the first conveying device. , waits on the downstream end side of the first conveying device in the conveying direction, and when the turn for wrapping comes, the second conveying device picks up the unvulcanized tire member waiting on the first conveying device. The leading end is held, conveyed and passed over the cylindrical outer circumferential surface of the forming drum, which rotates and initiates the winding of the unvulcanized tire component. On the other hand, the second conveying device once returns to its original position, and then holds and conveys the rear end of the unvulcanized tire member, and transfers it to the forming drum. By this time, the unvulcanized tire member has been wrapped around the cylindrical outer circumferential surface of the forming drum.
A slight gap is formed between the front and rear ends of the unvulcanized tire member, but at this time, the positioning presser presses the front end of the unvulcanized tire member toward the forming drum, and the second The conveying device cooperates with the forming drum to pull the rear end toward the front end, join it to the front end in a butt state, and complete the winding, so even an inexperienced person can easily handle unvulcanized tire parts. The front and rear ends can be easily butt-jointed. It also has the effect of improving quality and work efficiency.
