It is a conveyor that has attracted attention in recent years because it is capable of steeply inclined conveyance, has the advantage of requiring a small installation cross-sectional area because it is cylindrical or U-shaped, and is economical.

から欠落することがある。However, in these belt conveyors, no special measures have been taken for conveying a high-temperature object at 60 to 400 ° C., so that the high-temperature object is conveyed on either the forward path or the return path, and When transporting non-hot objects below ℃, for example, when transporting high-temperature objects on the front cover rubber side on the outward path, and transporting non-hot objects on the back cover rubber side on the return path, the front cover rubber subjected to thermal stress on the outward path However, on the return path, it becomes the outer surface and expands under the tensile force. When the front cover rubber is repeatedly subjected to such thermal deterioration and tensile force, a crack is eventually generated. When this crack occurs, a situation may occur in which the transported material enters the crack on the outward route and drops on the return route.
In this case, if the cover rubber is thin, curing (thermal deterioration) of the rubber proceeds to the inner core layer, and a part of the cover rubber may be missing from the core layer.

However, as the thickness of the cover rubber increases, the manufacturing cost of the conveyor belt itself increases, and the power cost of the conveyor transport line increases. In general, in a cylindrical or U-shaped belt conveyor, a steel cord or a polyamide cord or the like is used for a tensile member embedded in an inner core rubber, and reinforcing cloths are arranged on the upper and lower sides in many cases. Has the rigidity for maintaining the shape, but is not effective in preventing cracks as described above.

FIG. 1 is a cross-sectional view showing an example of a conveyor belt according to the present invention, wherein 1 is a front cover rubber, 2 is a back cover rubber, 3 is an intermediate layer rubber having a tensile member 4 bonded with an adhesive rubber 3a,
Reference numerals 5 and 6 are reinforcing cloths. Note that the adhesive rubber can be omitted. FIG. 2 is a perspective view showing the overall configuration of a cylindrical belt conveyor using the conveyor belt according to the present invention. In the drawing, 7 is a driven pulley, 8 is a driving pulley, and 9 is a conveyor belt according to the present invention having a cross section shown in FIG. 1 and is suspended between the two pulleys. The conveyor belt 9 is unfolded flat at the driven pulley 7, loads and transports a high-temperature object thrown from a chute 10 on one surface 9a (see FIG. 1), and a plurality of rollers 12 at a support frame 11A. As a result, when the conveyor belt 9 reaches the drive pulley 8 via the plurality of support frames (11A to 11Z), the conveyor belt 9 is again unfolded in a flat shape, and the surface of the pulley 8 is removed. The hot object is discharged to the belt conveyor 13 while rotating. The conveyor 13 advances in the direction of the arrow and transports the hot object to a predetermined place. Then, the chute 1 is placed on the other surface 9b (see FIG. 1) of the conveyor belt 9 around the pulley 8.
From 4, a non-high temperature object is input. The conveyor belt 9 is bent at a support frame 11Z by a plurality of rollers 12 into a cylindrical shape such that the surface 9b becomes an inner surface. Then, the conveyor belt 9 is unfolded flat at the guide roller 15 through the plurality of support frames (11Z to 11X), and discharges the non-high-temperature object to the belt conveyor 16. The belt conveyor 16 advances in the direction of the arrow, and conveys this non-hot substance to a predetermined place. Then, the conveyor belt 9 reaches the driven pulley 7 again via the guide rollers 17, 18, and 19,
Thereafter, the same operation as described above is repeatedly performed. FIG. 3 is FIG.
It is sectional drawing of the part of support frame 11X or 11Z. Next, in order to measure the resistance of the conveyor belt to crack growth due to repeated bending, a bending test was performed in accordance with JIS-K6301. In this case, the belt width is 160mm
And a 2.0mm diameter steel cord
It was arranged on the intermediate layer rubber at a pitch of 0 mm. The reinforcing fabric of the conveyor belt and subjected to the bending test, using R 1 or R 2 shown in Table 1 below. Then, for the combination of the reinforcing cloth and the intermediate layer rubber as shown in Table 2 below, JIS
According to -K6301, the test piece thickness was 13 mm and 30
The crack length after bending 00 times was measured. Table 2 shows the results. In Table 2, the meanings of the symbols M 1 and M 2 indicating the thickness division of the intermediate layer rubber are as shown in FIG.
