Abstract

(57) Abstract: [PROBLEMS] To provide a ringer roll or a laminated roll applicable to a place where liquid is splashed. By forming the end surface of the roll at a right angle to the body portion 3, it is possible to prevent the liquid from scattering to the rear surface of the roll and to improve the liquid drawability of the end portion of the roll.

Description

[Detailed description of the invention] [Industrial applications]

 Stacked rolls for transport and liquid drawing in equipment for processing strips of paper, aluminum, copper plates, steel plates, stainless plates, etc.

[Prior art]

 Conventionally, rubber lining rolls are often used, but from the viewpoint of slip resistance and wear resistance, laminated rolls as shown in Fig. 1 are used. As the material laminated on the roll, many kinds of materials such as paper, cloth, leather and synthetic fiber are used according to the application.

[Problems to be solved by the device]

 Corners 5 are always provided at both ends of the roll in which the sheet-like materials are laminated. The reason for this is that, as shown in Fig. 2, when the both ends of the body are laminated, the pressing flange 4 is made of metal, and the outer diameter is smaller than the wear-ground amount of the soft laminated sheet-shaped product, which causes sagging. Corner 5 is provided because 6 occurs. However, this corner 5 has a lot of splash 7 of the liquid due to centrifugal force from the gap between the corners of the ringer roll used in a pair or the place where the liquid is splashed, and splashes in the circumferential direction of the roll. The layered roll could not be applied to the ringer roll or the place where the liquid is splashed, because of the poor quality of the liquid drawn on the upper surface of the strip and the liquid drawability deteriorates. The present invention provides a laminated roll that eliminates these drawbacks.

[Means for Solving the Problems]

 FIG. 3 is a front partial view of the laminated roll of the present invention. A laminated sheet in which elastic rubber rings 8 whose roll end faces are perpendicular to the roll body surface 3 are attached to both ends of the laminated roll 1 and laminated. Eliminates the occurrence of sagging material 6. This eliminates the conventional corners 5 at both ends.

[Embodiment of the invention]

 A conventional laminated roll with corners 5 at both ends shown in Fig. 1 was used as a pair as a ringer roll for liquid squeezing. When 10 l / min of water was applied on the inlet side of the roll, the liquid in the body of the roll Although squeezing is possible 100%, the accumulated liquid in the roll body 3 flows to both ends along the surface of the roll, and 80% or more of the gap between the corners 5 at both ends is directed toward the rear of the roll as a splash 7 in the direction of the arrow. Scattered to. Further, the splash direction of the splash 7 is often scattered toward the center of the body of the roll, and it re-adheres on the belt-like material to cause quality defects. Therefore, according to the present invention, rubber rings 8 are attached to both ends of the body portion 3 of the laminated roll. FIG. 3 shows a front partial view of a laminated roll according to the present invention. The rubber ring 8 has a hardness of 60 to 70 degrees and a width A dimension of 50 mm. It is the one that lost 5. The width A of the rubber ring 8 is arbitrarily determined by the difference in the rolling force between the rubber ring 8 and the pair of rolls, and is not limited to 50 mm. As a result of the liquid drawing test using the laminated roll according to the present invention, the liquid drawing was achieved at 100% over the entire width of the roll body, and the splatter in the circumferential direction of the roll was completely eliminated in the roll body 3. As a result of mounting the rubber ring 8 having a width A of 10 mm, a small amount of splatter was generated at the end faces and the roll was splayed backward at both ends. The accumulated liquid in the body flows along both sides of the roll to both ends and is discharged to the side surface outside the body. However, in the laminated roll, there is a pressing flange 4 that presses the laminated sheets, and this flange surface Splash is generated to the rear, but since the flange 4 is smaller than the outer diameter of the laminated roll, the splash does not scatter to the center of the roll, but the flange 4 has a taper of 45 degrees. After that, Splash 7'has changed its direction of scattering from the rear to the side, and it has become more safe. Further, the shape of the pressing flange can be accommodated in the rubber ring 8'as shown in FIG. 4 to eliminate the protrusion of the roll end surface flange. Further, both the hardness and the material of the rubber ring 8 are lower than the material to be laminated and have elasticity, and urethane rubber, synthetic resin, nylon or the like may be used.

[Effect of the invention]

 As described above, by attaching the rubber rings 8 to both ends of the laminated roll, the laminated roll can be used even in a place where it is exposed to a linger roll or liquid, and when it is used as a pair as a ringer roll, the laminated roll is used. The outer diameters of the roll body 3 and the rubber ring 8 are usually the same, but the hardness of the rubber ring 8 is lower than that of the laminated roll body 3 and a material having elasticity is used. When the outer diameter of the rubber ring 8 is made 0.5 mm larger than the outer diameter of the laminated roll, the rubber rings 8 at both ends having a large outer diameter are strongly pressed by the central roll body 3, so that the liquid squeezing of the end surface is restricted. The effect such as the improvement of the property was also obtained.
