By the way, depending on the type of industry in which the belt conveyor is used, there are cases where it is desired to transport the powdery material to a high place.
For example, when a raw material is put into a high-rise facility such as a reduction furnace 1 as shown in FIG. 1, which has a height above the ground of about 100 m, a steeply inclined belt conveyor 2 capable of carrying a large capacity with a steep inclination is provided. is necessary. Since the conveyor belt for the steeply inclined belt conveyor 2 needs to have a function of conveying a steep angle without spilling the load, as shown in FIG. A corrugated side conveyor belt 5 having corrugated tabs 4 and 4 provided at both ends in the width direction along the length direction is generally used. As described above, in the corrugated side conveyor belt, the belt main body has a large rigidity in the width direction and the corrugated tabs are provided at both ends in the width direction, so that the corrugated side conveyor belt has a larger loading cross section than the ordinary belt. For example, the loading cross section (the hatched portion) 6 of the corrugated side conveyor belt 5 shown in FIG. 3B is larger than the loading cross section (the hatched portion) 8 of the ordinary belt 7 shown in FIG. 3A. Moreover, as shown in FIG. 4, the ordinary belt conveyor line 9 has a gentle inclination angle α with respect to the horizontal plane (generally α ≦ 3.
0 °), the inclination angle β of the corrugated side conveyor belt with respect to the horizontal plane of the conveyor line 10 is steep (β ≧ 4
Most of them are 5 °), and among them, β = 90 ° is in operation.

As described above, in the conventional structure of the belt main body of the corrugated side conveyor belt in which the conveying line has a steep slope with a large conveying amount, as shown in the transverse sectional view of the belt in FIG. Adhesive rubber was coated on one piece of the core body cloth 13, four core body cloths 13 were laminated, and an adhesive treatment was applied to the upper part of the core body cloth layer via the cushion rubber 14 to cover the adhesive rubber. A structure in which a reinforcing canvas (having a monofilament diameter of 0.3 to 0.5 mm) 15 is arranged in the width direction, and a cover rubber 16 is laminated on the upper part of the reinforcing canvas 15 and the lower parts of the four core canvases 13.

However, the rigidity in the width direction is not sufficient with only one reinforcing canvas, and due to the forward and reverse bending of the wrapping pulley and the disk roller, the body canvas is peeled off in a short period of time, or the corrugated ear straps are used. The mounting base may be cracked. In addition, the amount of bending at the central portion in the belt width direction is too large, and the corrugated earpiece or the cover rubber may come into contact with the transport facility and be damaged.

If the rigidity value in the width direction is less than 5 N / mm, the center portion of the width of the belt bends, and the bending in the width direction becomes severe due to the disk pulley that is applied to the outside of the end portion of the belt when the inclined portion and the horizontal portion are bent. There is an inconvenience that the mounting base of the corrugated earpiece is easily cracked. On the other hand, when the rigidity value in the width direction exceeds 8 N / mm, a large force is required to wind the head pulley and the tail pulley. There is a point. Therefore, the rigidity value in the width direction of the corrugated side conveyor belt obtained as described above is 5 to 8N.

In order to impart such a rigidity value in the width direction, a monofilament diameter of 0.3 to 0.5 mm is added to the reinforcing canvas.
It is preferable that two or more plies of this reinforcing canvas layer are provided at least in the width direction at a portion including the corrugated tab attachment portion by using the above thread. In particular, the range in which two or more plies of the reinforcing canvas layer are provided includes the corrugated ear bar mounting part of the belt-shaped belt main body because the corrugated ear bar mounting portion is locally bent in the width direction and cracks and canvas peeling are likely to occur. It is preferably 25 to 40% of the total width.

When 1.2 mm yarn is used, even one reinforcing canvas can secure sufficient rigidity in the width direction. In this case, if two or more plies of reinforcing canvas made of a yarn having a monofilament diameter of 0.8 to 1.2 mm are provided, the amount of bending in the width direction of the belt is reduced, but the flexibility is deteriorated, power consumption is increased, and the belt Since the durability is reduced, the monofilament diameter is 0.8 to 1.
It is preferable to use only one reinforcing canvas made of a large diameter yarn of 2 mm.

A belt-shaped belt main body and a corrugated side conveyor belt were prepared in the same manner as in Example 1 except that a plain cloth woven 4 mm polyester yarn was subjected to an adhesive treatment with resorcinol formalin, and one piece of the cloth covered with an adhesive rubber was used. Then, the rigidity value in the width direction and the bending at the center in the width direction were measured. The results are shown in Table 1. Regarding the belt durability, according to the operation test in the same actual line as in Example 1, cracks at the base of the corrugated ear piers occurred in 2 years, and peeling of the body canvas of the belt body occurred in 4 years. The abrasion of the cover rubber of the belt body also occurred in 4 years. (Comparative Example 2) A monofilament having a diameter of 0.
In the case of using two sheets of plain weave of 8 mm polyester thread that have been adhesively treated with resorcinol formalin and coated with adhesive rubber, two reinforcing fabrics 15 ', which are close to the body fabric, are used as shown in FIG. The belt-shaped belt body and corrugated side conveyor are the same as in Example 1 except that the core body cloth 13 has a width of 250 mm from both ends in the width direction, and two reinforcing cloths are not provided in the width direction central portion. The belt was obtained, and the rigidity value in the width direction and the flexure at the center in the width direction were measured. The results are shown in Table 1.

The following points are clear from Table 1 and the results of the above investigations. (1) The rigidity value in the width direction of the conveyor belt according to Examples 1 to 4 is larger than that of Comparative Example 1. In addition, Examples 1 to 1
The amount of flexure of the conveyor belt according to No. 4 is smaller than that of Comparative Example 1.

Further, in the conveyor belt according to the first embodiment, after the operation for three years, only a part of the base portion of the corrugated earpiece is cracked, and the extent of the crack has an influence on the conveyer work of the conveyor. It wasn't something to give. Further, the conveyor belts of Examples 2 to 4 are also judged to have the same crack resistance as that of Example 1 in view of the rigidity value in the width direction. (2) The amount of flexure of the conveyor belt according to Comparative Example 1 is large, and in particular, when the concentrated stress is applied to the corner portion of the disc pulley,
After operating for a year, a large crack was generated in the base of the corrugated earpiece, and after 4 years of operation, the body canvas of the belt body was peeled off, and wear was observed on the cover rubber of the belt body. As a result, it was judged that further operation could not be continued. (3) The conveyor belt according to Comparative Example 2 uses a reinforcing canvas made of a large-diameter monofilament yarn and has a two-ply structure in a part of the belt in the width direction, so that the amount of bending is small,
Like the conveyor belt of Comparative Example 1, it seems to have a short life because it is susceptible to bending by the drive (head) pulley and the driven (tail) pulley.

Since the present invention is constructed as described above, the amount of bending at the center portion in the width direction is small, and the corrugated tab mounting portion is less likely to be intensively deformed in the width direction at the end portion of the disc pulley. Since troubles due to cracks from the corrugated tab attachment portion are unlikely to occur, it is possible to provide a corrugated side conveyor belt having excellent durability.
