ている。2. Description of the Related Art In a reel used for winding a metal strip such as a cold-rolled steel sheet or aluminum, a divided segment on an outer peripheral portion is moved in a radial direction by an advancing and retracting rod for expansion and contraction, and the outer diameter of the reel is reduced. In general, a device that expands or contracts is used. The outer diameter of the reel is enlarged to take up a metal band, and after winding, the outer diameter is reduced to take out a metal band coil.

のスリーブが装着される。[0003] In the winding of the metal band by such an expansion-contraction type reel, gaps and steps between the segments are easily transferred to the inner diameter portion of the metal band coil when the segments are enlarged. A rubber sleeve is mounted on the outer periphery of the reel.

Its coil inner diameter is 20 inches or 24 inches,
The outer diameter of the reel is less than 20 inches, and a rubber sleeve having an outer diameter corresponding to the inner diameter of the coil when the reel is enlarged is mounted.

不良）が発生するという問題がある。However, in the winding by a reel on which a rubber sleeve is mounted, particularly when winding a thin and soft metal band, an ear wave (both ends in the width direction is elongated) at the inner diameter of the coil at the initial stage of winding. There is a problem that a shape defect that waves in the direction) occurs.

塑性縮みが発生することがある。The generation mechanism of this ear wave is considered as follows. The rigidity of rubber is, for example, 1/10000
, The diameter of the rubber sleeve is reduced by the surface pressure generated when the metal strip is wound. Assuming that the outer diameter of the rubber sleeve is Dr and the reduction amount of the rubber sleeve diameter is ΔD, a compression strain of Δε = ΔD / Dr is applied to the metal band at the inner diameter of the coil due to the deformation of the rubber sleeve. During winding, the winding tension is acting, so that tensile stress acts in the longitudinal direction on the metal band inside the coil, but after winding, the winding tension is released. Compressive stress due to strain or the like acts. Therefore,
The metal band at the inner diameter of the coil is deformed by bending and compression,
Plastic shrinkage may occur.

発生は、製品の品質を損ない、しかも歩留まりの大幅な
低下をもたらすことになる。However, in general, a metal strip has a convex plate crown (a central portion in the plate width direction is thick and both ends are thin).
The surface pressure in the plate width direction during winding is high at the center of the plate width and lower at both ends, so the rubber sleeve has a large reduction in the diameter at the center of the width and has a drum-shaped shape. Make a deformation. Therefore, the compressive stress in the longitudinal direction of the plate acting on the metal band at the inner diameter of the coil is large at the center in the width, small at both ends, and appears as an ear wave. The generation of this ear wave impairs the quality of the product and leads to a significant decrease in yield.
【０００８】耳波の発生を防止するために、金属帯の板
クラウンの低減、巻取張力の低下、ゴムスリーブの硬度
アップや金属帯の降伏点アップ、等の対策が考えられ
る。In order to prevent generation of ear waves, measures such as reduction of the crown of the metal band, reduction of the winding tension, increase in the hardness of the rubber sleeve, and increase in the yield point of the metal band can be considered.

用途により決まっており、変更はできない。[0009] However, it is extremely difficult to roll a metal strip having a uniform thickness in the width direction without a sheet crown, and it is not practical with great capital investment. The reduction in the winding tension has a problem in that the surface pressure between the coils is reduced to cause slip, and the coil is crushed, and there is a limit in reducing the winding tension. The increase in the hardness of the rubber sleeve causes a defect called an end mark in which the leading end of the metal band does not sink into the rubber sleeve and the tip of the metal band breaks. The yield point of the metal strip is determined by the application of the product and cannot be changed.

Although a method of providing a crown on a rubber sleeve has been proposed, the rigidity of rubber is extremely low as compared with metal, and the effect of suppressing the ear wave due to the convex crown of the rubber sleeve is small.

生を防止する方法を想到した。The inventors of the present invention have studied the mechanism of occurrence of flat defects during winding of a steel sheet and its countermeasures, and inserted a sheet having lower rigidity than the steel sheet between the steel sheets at both ends in the sheet width direction. A method for preventing the generation of ear waves was conceived by compensating for the reduction in the thickness of the plate at both ends of the width due to the crown so that the deformation of the rubber sleeve can be regarded as substantially equivalent to the case of a steel plate having a rectangular cross section.

As shown in FIG. 1, when the metal band 3 is wound by the reel 2 having the rubber sleeve 1 mounted on the outer periphery, the present invention has a rigidity lower than that of the metal band 3 between the metal bands 3 at both ends 4 in the plate width direction. Sheet 5
a and 5b are inserted and wound around the reel 2 in a state where the metal band 3 and the sheets 5a and 5b are overlapped. In the figure, reference numeral 6 denotes a coil.

When winding a steel plate, an aluminum sheet may be used in addition to the above.

It is desirable that the tensile strength is 2 kgf or more (according to JIS P8113), and furthermore, when winding up the steel sheet, the moisture of the paper is reduced to 6% of the total weight from the viewpoint of rust prevention.

の０．５倍以上２．０倍以下である。If the thickness of the sheet is excessively large with respect to the sheet crown, the outer surface of the coil during winding becomes a drum shape, and plastic elongation occurs at both ends of the outer diameter portion of the coil during the middle and later stages of winding, causing an ear wave and Become. If the sheet thickness is too small, the effect of complementing the plate crown is small, and ear waves are likely to be generated at the inner diameter of the coil. Preferably, the sheet thickness is 0.5 times or more and 2.0 times or less of the sheet crown.

In this size, the sheet crown (the sheet thickness difference between the sheet width center and the edge 25 mm) is usually about 20 μm, and a sheet having a thickness of about 10 to 40 μm may be used.

で対応できる。The sheet is inserted at both ends of the metal band. If the width of the sheet is too small with respect to the width of the metal band, the surface pressure of the sheet insertion portion increases, and a ridge (locally) is formed on the surface of the metal band at that position. Medium elongation). If the sheet width is too large, the effect of complementing the plate crown is small, and ear waves are likely to be generated at the inner diameter of the coil. Further, since the distance between the sheets is short, the sheets overlap due to the meandering of the sheets, and indentation flaws are easily generated on the surface of the metal band. Preferably, the sheet width is 1 of the board width.
It is / 4 or more and 1/3 or less. For example, if the cold-rolled steel strip has a width of 900 to 1200 mm, a sheet having a width of 300 mm can be used.
