Crossing while rolling on the upper surface of the sending conveyor 25,
The joint portion 14 between the strip-shaped sheet body 5b and the cut sheet body 5a is entirely pressed.

In FIG. 4, the basic angle φ of the adjusting arm 12 with respect to the elevating member 33 in the direction orthogonal to the conveying path 11 is set by rotating the screw shaft 37 of the swing drive mechanism 30.
The inclination angle θ of 5a (the angle of the cord forming the sheet body) is set to be almost equal. Splicer feed motor 49
Is rotated and the timing belt 27 is driven, whereby the splicer 13 is retracted from the standby position S at a high speed, and is moved in the anti-conveyance direction B, that is, in the direction of the cutting sheet body 5a at the conveyance path start end portion P position. However, as shown in FIGS. 4 and 5, during the backward movement, the basic angle φ becomes larger than the inclination angle θ by an angle α, as indicated by an imaginary line.
The tip 21 of the adjusting arm 12 is swung in the transport direction H. Here, the angle α is an angle corresponding to the number of rotations of the motor required for the angle adjusting motor 38 to rise until reaching a constant speed after starting, and the other (right) cutting sheet body front end detection sensor 10 The motor 38 is set to reach a predetermined rotation speed when the other front end portion 3 of the cut sheet body 5a is detected. When the reverse speed switching sensor 48 passes through substantially the center of the front end portion 3 of the supply sheet body 5a and detects the front end portion 3, the splicer feed motor 49 responds to the command signal from the sensor 48 to change the reverse speed of the splicer 13. Lower.

Next, as described above, by setting the angle of the adjusting arm 12 to θ + α, as shown in FIG. 6, the base end portion 20 of the adjusting arm 12 near the pivoting portion 19 is first cut. The front end portion 3 of the sheet body 5a is reached, and the one (left) front end portion detection sensor 9 detects one end of the front end portion 3 of the cut sheet body 5a, and then, after a predetermined pulse has elapsed or a predetermined time by a timer. After a lapse of time, the splicer feed motor 49 (see FIG. 4 etc.) is stopped based on the signal of the sensor 9, and the retraction of the splicer 13 is stopped. In this state, the vacuum cup 42 provided in the vicinity of the one (left) front end detection sensor 9 is located at a distance from the front end edge of the cut sheet body 5a, that is, at the front end extraction margin m.

Simultaneously with the backward stop of the splicer 13, as shown in FIG. 7, the screw shaft 37 is rotated to swing the tip end portion 21 of the adjusting arm 12 in the anti-conveyance direction B, and the other (right) cutting sheet body front end. The part detection sensor 10 detects the other (right) end of the front end part of the cut sheet body 5a, and the adjustment arm 12 is set to stop after a predetermined pulse or a predetermined time has elapsed. At this time, the other (right) front end detection sensor
The vacuum cup 42 provided near 10 is the cutting sheet body 5a.
Is at a predetermined distance from the front edge of, i.e., at the front end extraction margin m. In this way, the adjustment arm 12 is moved to the cutting sheet body 5a.
It is possible to stop the vacuum cup line C in parallel with the front end portion 3 of the cutting sheet body 5a.

Thereafter, the vertical air cylinder 36 of the lifting mechanism 32 shown in FIG. 1 is operated to lower the lifting member 33 to bring the respective vacuum cups 42 ... The front end portion 3 is adsorbed and held by pressure.

At this time, the suction device 6 holds the extraction position of the front end extraction margin m from the front edge of the cut sheet body 5a in the width direction.

Each vacuum cup 42 is always elastically urged downward by a spring (not shown) or the like.

As shown in FIG. 8, the front end portion 3 of the cut sheet body 5a is sucked and held by the suction device 6 and is slightly raised to lift the front end portion 3.

Next, as shown in FIG. 9, the splicer 13 is advanced in the conveying direction H together with the cutting sheet body 5a.
By rotating 37, the tip end portion 21 of the adjusting arm 12 is swung in the anti-conveying direction B as shown by the phantom line, and the basic angle φ of the adjusting arm 12 is set smaller than the inclination angle θ by the angle α. I'll do it.

After that, the splicer 13 passes through the position of the low speed switching sensor 50, and the sensor 50 detects this, whereby the forward speed of the splicer 13 is reduced based on the command signal, and the splicer 13 is advanced at a low speed. As described above, since the angle of the adjusting arm 12 is set to θ−α, the base end portion 20 of the adjusting arm 12 first reaches the rear end portion 4 of the belt-shaped sheet body 5b, and the one (left ) The belt-shaped sheet body rear end detection sensor 7 detects one (left) end of the rear end portion 4 of the belt-shaped sheet body 5b, and based on a command signal from the sensor 7, after a predetermined pulse has elapsed or a predetermined time has elapsed, Adjusting arm 12
The splicer 13 stops in a state of intersecting the rear end portion 4 of the belt-shaped sheet body 5b. At this time, when viewed in a plan view, one (left) end of the front end portion 3 of the cut sheet body 5a and the left end of the rear end portion 4 of the belt-shaped sheet body 5b are in a superposed relationship with a height h therebetween (the tenth portion). (See Figures and Figures 11 and 12).

Next, as shown in FIG. 13, while the splicer 13 is stopped, the adjusting arm 12 is swung in the conveying direction H, and at the same time, the other (right) strip-shaped sheet rear end detection sensor 8 is used to strip the strip-shaped sheet. The right end of the rear end portion 4 of the body 5b is detected, and a predetermined pulse (the same pulse as in the case of the one rear end portion detection sensor 7) or a predetermined time has elapsed based on the command signal, that is, in a plan view. The adjusting arm 12 stops when the rear end portion 4 of the strip-shaped sheet body 5b and the front end portion 3 of the cut sheet body 5a have the overlapping margin n of the same width in the width direction. After that, the suction device 6 is lowered to bring the front end portion 3 of the cut sheet body 5a into contact with the rear end portion 4 of the strip-shaped sheet body 5b, thereby forming a superposed joint portion.
Forming 14 Next, although not shown, the press rods 45 of the joint press portion 15 provided on the adjusting arm 12 are lowered, and the joint portions 51 are partially pressed in the left-right direction at appropriate intervals, so that both sheet bodies 5a, Crimp 5b (see Figure 1). At this time, the negative pressure of the adsorption device 6 is released at the same time, and the adsorption device 6 is raised. Further, the press rods 45 ... Are also raised.

At this time, if there is a next cut sheet body 5a on the starting end side of the transport path 11, a starting end position sensor (not shown) detects it and repeats the above operation. If there is not, the splicer 13 moves backward to the standby position S and stands by for a stop.

The joining of the two sheet bodies 5a, 5b is performed on the joint table 52 of the separator 53 provided at the joining position Q on the terminal end side of the transport path 11 as shown in FIGS. The joint portion 14 is peeled off from the joint table 52 by the peeling plates 54 ... Which are pushed upward from the long holes of the joint table 52. That is, the lifting cylinder 55 raises the plurality of peeling plates 54 at the same time, and the joint portion 14 is slightly lifted. As a result, the strip-shaped sheet body 5b is smoothly delivered.

The strip-shaped sheet body 5b joined to the cut sheet body 5a is delivered in the transport direction H by the delivery conveyor 25 as shown in FIG. 18, but the rear end portion 4 of this strip-shaped sheet body 5a is switched to the low speed conveyor. After passing through the low-speed switching sensor 50 which also serves as a sensor, the sending-out conveyor 25 is switched to a low speed, and as shown in FIG. 19, further stops after passing through the conveyor stop sensor 57. As a result, the joint portion 14 is positioned at the position T where the joint crimping mechanism 14 is arranged. Then, as shown in FIG. 19, in the joint portion 14, the full surface press roller 59 of the joint pressure bonding mechanism 58 provided on the upper side of the feeding conveyor 25 traverses the joint portion 14 in the width direction of the conveyor to perform full pressure bonding. To be done. In this way, the strip-shaped sheet body 5b is sent out intermittently one after another and wound up by the winding roller (not shown).

In the above embodiment, the splicer 13 is moved forward and backward by the motor driven timing belt 27. However, unlike this, it is also preferable to use a ball screw or a fluid pressure cylinder. Further, the adjustment arm 12 may be rocked by a rocking cylinder or the like. Instead of the vacuum cup 42, a magnet may be used in a magnetic material sheet body such as a steel cord cloth.

〔The invention's effect〕

Since the present invention is configured as described above, it has the effects described below.

Even if the shape of the cut sheet body 5a is not perfect, or is not a precise parallelogram or a rectangle, the overlap margin n of the joint portion 14 between the rear end portion 4 of the belt-shaped sheet body 5b and the front end portion 3 of the cut sheet body 5a. Can be easily and highly accurately bonded to each other at any position in the width direction, and a high quality tire constituent material can be provided.
In particular, radial tires have a negative effect on the uniformity and impair the tire performance unless the polymerization margin n of the joint portion 14 is constant, but the present invention can eliminate such drawbacks.
