- a plurality of slide plates 132b are supported in the width direction along the downstream side surface of the pressing member 132a so as to be able to move up and down, and the clamp claws 132c swing to slide the slide plates 132b.
- the leading end of the sheet-like material 120 is sandwiched therebetween.
- a rubber plate 132d is attached to each slide plate 132b, and a clamp claw 132c is provided between the slide plate 132b and the slide plate 132b via the rubber plate 132d.
- the slide plate 132b and the rubber plate 132d can be independently lifted and lowered independently of the end portions sandwiched between the slide plate 132b and the rubber plate 132d. .
- the rear hand 133 has a symmetrical structure with the front hand 132 by means of a holding member 133a, a slide plate 133b, a clamp claw 133c, a rubber plate 133d, etc., so that the rear end of the sheet-like material 120 is securely formed. Can be sandwiched.
- the holding members 132a, 133a and the like can turn in a horizontal plane.
- An end face shaping step and a transport step by the end face shaping apparatus 130 having the above-described structure will be sequentially described with reference to FIGS. 14 and 15.
- FIG. 14 and FIG. 15 are explanatory diagrams showing movement over time by a simplified diagram consisting of only main elements.
- the front hand 132 and the rear hand 133 are located at the home position above the downstream part of the belt conveyor 123, and the sheet material 120 is conveyed by the belt conveyor 123 while being centered. In this case, the leading end is located between the belt conveyor 123 and the belt conveyor 124.
- the detection sensor 127 detects the end face shape of the tip of the lithographic material 120. Then, the front hand 132 grips the leading end of the sheet-like material 120 at a predetermined position using the above-described bent body (not shown) or the like (see FIG. 142).
- the front hand 132 moves forward while gripping the leading end of the sheet material 120, and conveys the sheet material 120 by pulling the sheet material 120 forward with the driving of the belt conveyors 123 and 124 (see Fig. 14-3). .
- the required slide plate 132b is raised and lowered while moving on the belt conveyor 123, and the tip is deformed and shaped. Let it be.
- twist shaping by turning the holding member 132a is also performed.
- the data of the shape of the tip surface should be corrected according to the shaped part and the amount. After the sheet material 120 is drawn out and conveyed by a predetermined amount, the conveyance is stopped, and the sheet material 120 is cut into a fixed length by the cutter 6 (see FIG. 14 1).
- the cutter 126 is retracted, the detection sensor 127 is moved to a predetermined position, and the end surface shape of the rear end of the sheet material 120 cut to the fixed length and the end surface shape of the front end of the other sheet material 120 are detected by the detection sensor 127. I do.
- the rear hand 133 is moved to grip the rear end of the sheet-shaped material 120 cut at a predetermined position at a predetermined length (see FIG. 155).
- the front hand 132 grasps the front end of the sheet material 120 and the rear hand 133 grasps the rear end thereof, and conveys the sheet material 120 cut to a fixed length to the molding drum 125 in cooperation with the drive of the belt conveyor 124. (See Figure 156). After gripping the rear end during this conveyance, the hand 133 shapes the end face shape of the rear end of the sheet material 120.
- the data of the shape of the front end face is compared with the data of the shape of the rear end face, and the rear hand 133 is twisted and shaped by turning the holding member 133a so that the rear end face shape can be abutted against the front end shape. Partial shaping by raising and lowering the slide plate 133b.
- the front hand 132 sticks the leading end of the sheet material 120 to the forming drum 125, the rear hand 133 releases the rear end of the sheet material 120, and drives the belt conveyor 124 and rotates the forming drum 125.
- a fixed-length sheet-like material 120 is wound around the periphery of the forming drum 125 (see FIG. 157).
- the front hand 132 and the rear hand 133 return to the home position. Thereafter, the front end surface and the rear end surface of the fixed length sheet-like material 120 wound around the forming drum 125 are joined by an end face pressure welding device or an ultrasonic welding device. Since the end face shape is corrected according to the tip end face shape, it is reliably joined with high dimensional accuracy.
- the shape of the rear end face is adjusted to match the shape of the front end face of the sheet material 120 cut to a fixed length, the shape may be adjusted so that the shape of the front end face matches the shape of the rear end face. Also, the shape of the front end face and the rear end face may be shaped so as to conform to the reference shape.
- an end face pressing step and an ultrasonic welding step in another example will be described with reference to FIGS. 16 to 18.
- the unvulcanized rubber members come into close contact with each other and the lower layers of the leading end 151a and the rear end 151b of the cascading ply 151 are difficult to move. It is difficult to match them, and therefore, as shown in FIG. 17, the end surfaces of the front end portion 151a and the rear end portion 151 are in contact with each other at the upper layer portion, but cannot contact at the lower layer portion, and the gap S a is not formed. It may be formed.
- welding is performed by the same oscillator 162 as described above using an ultrasonic welding device at the next stage as shown in FIG.
- the rubber is heated and melted by ultrasonic irradiation, filling the void Sa and covering the entire end surfaces. It can be joined over.
- the vibrator 162 is welded while moving in the width direction at the pressure contact portion directed in the width direction of the force ply 151, so that the air in the gap Sa is sequentially expelled to the side and sequentially filled with the melted rubber. As a result, welding is performed reliably. Therefore, both ends of the carcass ply 151 can be easily joined with sufficient joining strength.
