Such a main table 20 is smoothly connected to the first main conveyor 18 and the sub-conveying section 7, and can convey the belt-shaped material G smoothly. Further, since the strip-shaped material G on the main table 20 is conveyed by the second main conveyor 19, there is no fear that the strip-shaped material G stays on the main table 20. FIG.

As shown in FIGS. 3 and 5, the sub-table 21 of this embodiment is configured to be movable in the vertical direction b. The table 17 preferably includes a table driving section 22 for moving the sub-table 21 in the vertical direction b. The table drive unit 22 of this embodiment moves the sub table 21 to a first position (shown in FIG. 3) at the same height as the main table 20 and a second position (shown in FIG. 5) located below the main table 20. shown).

As shown in FIG. 4, the sub-table 21 is separated from the main table 20 by, for example, a first sub-end 21a on the upstream side and a second sub-end 21b on the downstream side in the transport direction c. The first minor end 21a preferably has a shape substantially equal to the first major end 20a. The second minor end 21b preferably has a shape substantially equal to the second major end 20b. With such a table 17, the gap between the main table 20 and the sub-table 21 is small, and there is no possibility that the strip-shaped material G is caught.

Such a sub-table 21 allows the cutting angle to be changed by the cutting device 5, which will be described in detail later, and can cut the strip-shaped material G at an angle suitable for it.

The first sub-end portion 21a of the present embodiment includes a third linear portion 21e that extends linearly while being inclined at an angle different from that of the first linear portion 21c with respect to the conveying direction c. The third straight portion 21e preferably extends continuously from the first straight portion 21c. In addition, the second sub-end portion 21b extends linearly at a position opposed to the third straight portion 21e in the conveying direction c and inclined at an angle different from that of the second straight portion 21d with respect to the conveying direction c. A straight portion 21f is included.

The angle θ3 of the third straight portion 21e with respect to the conveying direction c is preferably equal to the angle θ2 of the second straight portion 21d with respect to the conveying direction c. The angle θ4 of the fourth straight portion 21f with respect to the transport direction c is preferably equal to the angle θ1 of the first straight portion 21c with respect to the transport direction c. Such a sub-table 21 allows cutting at different cutting angles by the cutting device 5 to be performed more smoothly.

Note that the first sub-end portion 21a may be composed of only the first linear portion 21c. Similarly, the second sub-end portion 21b may be composed of only the second straight portion 21d. In this case, the upper surface of the sub-table 21 is preferably formed in a substantially trapezoidal shape. Such a sub-table 21 has a simple shape and can suppress manufacturing costs.

As shown in FIGS. 3 to 5, the cutting device 5 of this embodiment is positioned above the sub-table 21. As shown in FIGS. The cutting device 5 is desirably movable in the vertical direction b by a vertical position changer (not shown). Such a cutting device 5 can be lowered when cutting the strip-shaped material G and raised when conveying the strip-shaped material G. As shown in FIG.

For example, the cutting device 5 may be fixed at a height that allows cutting the strip material G without being moved in the vertical direction b. In this case, the cutter 23 of the cutting device 5 is desirably movable to the outside of the main conveying section 6 in the axial direction a.

The cutting device 5 of this embodiment includes a cutter 23 that travels in the cutting direction. It is desirable that the cutter 23 cuts the belt-shaped material G with the tip positioned below the upper surface of the main table 20 while the sub-table 21 is moved to the second position (shown in FIG. 5). The cutter 23 preferably runs along the first main end 20a or the second main end 20b. Such a cutter 23 can cut the belt-shaped material G reliably and accurately.

In this embodiment, the strip material G is supported by the first main table 20A and the second main table 20B on both sides of the cutting position in the conveying direction c. Cutting accuracy can be further improved.

The cutting device 5 of this embodiment includes an angle changing section 24 that changes the cutting angle of the belt-shaped material G with respect to the conveying direction c. For example, the angle changing portion 24 has a first angle at which the cutter 23 travels above the first straight portion 21c and the fourth straight portion 21f, and a first angle at which the cutter travels above the second straight portion 21d and the third straight portion 21e. It is possible to change the cutting angle to two angles. The angle changer 24 preferably rotates the cutting device 5 around the position where the sub-table 21 has the smallest length in the transport direction c. Such a cutting device 5 can cut the strip material G at an angle suitable for it.

Next, with reference to FIGS. 1 to 5, the operation of the conveying system 1 of this embodiment when conveying and cutting the belt-shaped material G will be described.
In the conveying system 1 of the present embodiment, first, the belt-shaped material G is attached to the supply device 4 while being wound around the reel 10 in advance. The first supply device 8 is attached by moving the reel 10 in the axial direction a, for example. The second supply device 9 is attached by moving the reel 10 in the conveying direction c, for example. Such a supply device 4 facilitates replenishment of the strip-shaped material G, and can shorten the working time.

Next, the strip-shaped material G is supplied from, for example, the first supply device 8 or the second supply device 9 to the first sub-transport section 11 or the second sub-transport section 12 of the sub-transport section 7 . At this time, the transport drive unit 15 preferably connects either the first sub-transport unit 11 or the second sub-transport unit 12 to the main transport unit 6 . The first sub-conveying section 11 or the second sub-conveying section 12 that is connected to the main conveying section 6 can convey the strip material G to the main conveying section 6 . Such a sub-conveying section 7 can smoothly convey an arbitrary strip-shaped material G out of a plurality of types of strip-shaped materials G. As shown in FIG.

Next, the main conveyor 16 of the main conveying section 6 of the present embodiment conveys the strip-shaped material G by a predetermined length while the sub table 21 is moved to the first position (shown in FIG. 3). It is desirable that the main conveyor 16 conveys the strip material G in synchronization with the first sub-conveyor 13 of the first sub-conveyor 11 or the second sub-conveyor 14 of the second sub-conveyor 12 .

At this time, the belt-shaped material G fed from the feeding section 6a of the main conveying section 6 is wound around the tire forming drum 2 rotating in synchronism with the main conveyor 16 to form a tire. Such a main transport section 6 can smoothly transport the belt-shaped material G without being caught on the table 17 .

The main conveyor 16 stops conveying, for example, after conveying the strip-shaped material G by a predetermined length. In this embodiment, the strip-shaped material G whose transport has been stopped is cut after the cutting device 5 and the sub-table 21 respectively move downward. At this time, the cutter 23 of the cutting device 5 preferably travels along the first main end 20a or the second main end 20b. In such a cutting device 5, since the vicinity of the cutting position is supported by the first main end portion 20a or the second main end portion 20b, the cutting precision can be improved.

Although the particularly preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments and can be modified in various ways.
