Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for applying a cushioning material onto the surface of a metal strip for preventing the generation of end marks when winding a metal strip.

[Prior Art]

As shown in FIG. 4, when the metal strip 1 is wound on the reel 8, the thickness of the front end portion of the metal strip 1 ranges from several turns to several tens of turns from the start of winding the metal strip 1. The end mark 1a is generated due to the step. If the end mark is present, it cannot be used as an exterior material for electric appliances, automobiles, etc. Therefore, it must be cut off over a range of several turns to several tens of turns from the edge of the winding end of the metal band. For this reason,
The product yield of the metal strip is significantly reduced.

As a conventional technique for preventing this end mark, a cushioning material such as a cut piece of corrugated paper is interposed in the range where the leading edge of the metal strip overlaps with the second roll (Japanese Patent Laid-Open No. 59-1019). Japanese Patent Publication), the height difference between the metal strip and the reel surface is alleviated by rolling the metal strip so that the thickness is reduced by a certain length from the edge of the reel winding tip, and as a whole, it is thinly rolled. A device that attempts to obtain the same effect as when the taper is made a little (Japanese Patent Laid-Open No. 61-1)
Japanese Patent No. 26927), in which the edge portion of the winding end of the metal band is tapered by a swaging roll (Shokai Sho 52).
No. 038138) is known.

[0004]

As a method of inserting a cushioning material between the front end portion of the metal band and the overlapping position of the metal band of the next winding when winding the metal band, when the front end of the metal band is wound on the reel, the conventional manual force is applied. Although the cushioning material was inserted in this, there was a danger in this work and there was a safety problem. In addition, the above-mentioned JP-A-59-1
In the method described in Japanese Patent No. 019, since the width of the metal strip is not constant, it is necessary to prepare various kinds of cushioning materials according to the width of the metal strip. Further, since the cushioning material may be displaced when it is inserted, it is necessary to lengthen the insertion range of the cushioning material to suppress the displacement. Therefore, the length of insertion of the cushioning material must be longer than necessary.

[0005]

According to the present invention, various cushioning materials are used when inserting the cushioning material between the second winding edge and the winding leading edge of the metal strip for winding the metal strip on the winding reel. The present invention provides a method that can be safely and easily inserted depending on the metal band width, and more particularly, a method and a device for attaching a cushioning material with an adhesive in the metal band width direction.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. An example of the band-shaped cushioning material sticking device is shown in FIG. 1 (front view) and FIG. 2 (side view, but a pedestal is omitted). The cushioning material pasting device 2 includes a cushioning material supply reel 3, a cushioning material cutting machine 4, a cushioning material pressing device 5, and a plate width direction moving mechanism 6. In this device 2, the band-shaped cushioning material 3a is attached in the width direction of the metal band 1. The position X (see FIG. 3) in the longitudinal direction of the metal band to which the cushioning material 3a is attached is the position (X = 0) at the front end of the metal band or at a position (X = where the reel 8 is one round from the front end of the metal band). π × outer diameter Y), and the tape is attached to the surface where the tip of the metal strip and the metal strip of the next roll overlap during reel winding.

The cushioning material 3a has a width of 10 to 500 mm and is made of a material such as resin, fiber or rubber having elasticity, and known materials such as foamed polyethylene, foamed polyurethane and cardboard can be used. The width of the band-shaped cushioning material depends on the thickness of the metal band, but if it is less than 10 mm, the end mark preventing effect is small, and if it is 500 mm or more, the end mark preventing effect does not change and is uneconomical.

The thickness of the band-shaped cushioning material is about 1 to 5 mm, though it depends on the material and the thickness of the metal band to be wound. Further, an adhesive is applied to the sticking surface side of the band-shaped cushioning material, so that the band-shaped cushioning material is firmly stuck to the surface of the metal band.

In FIGS. 1 and 2, the position of the metal strip is X = πY (=
In the example of the position where the circumference of the reel 1 is entered), the metal band stops at the position where the tip of the metal band 1 advances by a distance πY from the position of the pressing roller 5a. At that time, the band-shaped cushioning material attaching device 2 is located at one end of the metal band 1. The strip-shaped cushioning material 3a supplied from the cushioning material supply reel 3 is attached to the metal strip 1 by the pressing roller 5a of the cushioning material pressing device 5. At this time, the cushioning material attaching device 2 is moved toward the opposite width end by the plate width direction moving device, and the strip-shaped cushioning material is sequentially stretched in the plate width direction. When the cushioning material cutting machine 4 reaches the opposite width end of the steel strip 1, the cushioning material cutting machine 4 cuts the strip-shaped cushioning material 3a,
The band-shaped cushioning material 3a is attached over the entire width of the metal band 1.
(A series of movements can also be fully automated. An example of an automatic sequence is shown in Fig. 5.)

In the next embodiment, as shown in FIG.
On a reel with an outer diameter of 508φ with a rubber sleeve fitted around
Ultra low carbon steel plate (C = 0.002%, TS = 18kgf
/ Mm² , 2.0mm thickness x 900-1,200mm width)
It was. The cushioning material sticking device is the one shown in FIGS. 1 and 2.
The cushioning material used is expanded polyethylene with a thickness of 3 mm and a width of 100 mm.
Adhesive is applied to the attachment surface.

The end of the belt-shaped cushioning material is 508φ × π = 1.6 m
The band-shaped cushioning material was attached to the advanced position by the apparatus shown in FIGS. 1 and 2 in the automatic sequence shown in FIG. As a comparative example, a case where a cushioning material is manually inserted into the vicinity of the leading edge of the metal strip is shown. Table 1 shows a comparison of the amount of cushioning material used and processing time, and Table 2 shows the length of the end mark generated using this apparatus.
