(Prior art) In a strip production line, the strip is passed through various lines such as a cold rolling line for cold rolling to a predetermined thickness, a line for cleaning surface deposits or dirt, a continuous annealing line, or a surface treatment line. be done.

In such strip production lines, different conveyance rolls are used depending on the processing content of each line and the properties of the strip, such as temperature resistance, chemical resistance, oil resistance, and abrasion resistance.

因となる。
Among the purposes for which conveyor rolls are used, slip resistance is the most problematic. In particular, the tension bridle roll is an important roll because it allows the tension of the strip between devices to be independent. If this conveyor roll slips, the tension of the strip becomes disturbed, causing various troubles.

The tension of the strip varies depending on the material, thickness, width, and processing details of each line.
A conveying roll is required that can thread the strip with the desired tension without causing the strip to slip.

As a conventional conveyor roll, for example,
As described in Japanese Patent No. 61115, there is a roll having a protruding tread pattern on the surface of a rubber-lined roll.

In addition, there are conveyor rolls in which particulate fixed substances or inorganic or organic fibers are mixed into the rubber lining, and a part of it is exposed on the roll surface (for example,
618719), when the strip is conveyed, fine particles and dirt adhere to the surface of the conveying roll, which lowers the coefficient of friction and reduces the bridle effect.

(Means for Solving the Problems) The gist of the present invention is to alternately use soft rubber lining materials and hard rubber lining materials, and to mix the soft rubber lining materials and the hard rubber lining materials in a width ratio of 1:2 to 2 on the roll surface. 5, the conveyor roll has excellent slip resistance, characterized in that it is disposed on the outer periphery of the roll body to form the roll surface.

Hereinafter, the present invention will be described in detail based on an implementation order with reference to the drawings.

In the drawings, reference numeral 1 denotes a roll body, and a soft rubber lining material 2 and a hard rubber lining material 3 having different hardnesses are provided on the outer periphery of the roll body.

The soft rubber lining material 2, the hard rubber lining material 3, and their arrangement will be described in detail.

The soft rubber lining material is, for example, JIS-K-
A material with a hardness of 10 to 80 after vulcanization is used with a spring-type hardness tester type A specified in 6301 Vulcanized Rubber Testing Method, and the hard rubber lining material 3 is harder than the soft rubber lining material 2 used. For example, those having a hardness of 20 to 100 are used.

The soft rubber lining material 2 and the hard rubber lining material 3 are arranged alternately at a predetermined width as shown in FIG. It is set up.

The widths of the soft rubber lining material 2 and the hard rubber lining material 3 on the roll surface are set at a width ratio of 1:2 to 5. If this ratio is less than 1, the width of the soft rubber lining material on the roll surface will be narrower than that of the hard rubber lining material, and the suction effect on the conveyed strip will be reduced. On the other hand, if the width ratio exceeds 5, the width of the soft rubber lining material applied to the roll surface becomes too large, and also in this case, the adsorption effect on the specific conveying strip becomes small, resulting in a decrease in slip resistance.

In addition, the soft rubber lining material 2 and the hard rubber lining material 3 can be arranged by, for example, providing the hard rubber lining material 3 on the outer periphery of the roll body 1, and then providing a certain interval on the surface of the rubber lining material 3. A groove is formed, and an unvulcanized soft rubber whose rubber hardness after vulcanization is different from that of the hard rubber lining material 3 is embedded and bonded in the groove. A conveying roll 4 with excellent slip properties is manufactured.

In the present invention, by arranging rubbers with different hardnesses, when a certain load is applied to the contact surface between the conveyed strip and the conveyance roll 4, the rubber in the portions with lower rubber hardness has a lower hardness. The compressive deformation is larger than that of the rubber in the high hardness parts, and the place where the difference in compressive deformation is large is the boundary between the high rubber hardness part and the low rubber hardness part, and a vacuum situation occurs in the low rubber hardness part. The vacuum condition causes an adsorption phenomenon, which is thought to be the reason why the excellent slip resistance properties are obtained.

The conveyance roll 4 is provided as a bridle roll 6 at the input/output side of a processing device, for example, a continuous annealing line 5 as shown in FIG. 3, and applies a desired tension to the strip 7 to thread the strip.

(Effects of the Invention) Since the conveying roll 4 of the present invention has a roll surface configured by alternately disposing rubbers of different hardness at predetermined intervals, desired tension can be applied without causing slips. Strip 7 can be passed through.

Further, since the surface of the conveyance roll 4 of the present invention has no concave portions as shown in FIG. 2, no pattern is transferred from the roll surface to the strip.
