JPH01321021A - Tail end treating method for extremely thin metallic band sheet coil - Google Patents

Abstract

PURPOSE:To eliminate whirling of the tail end of the coil and to prevent tail end cracking by giving adhering function to the surface to be abutted with the peripheral surface of the coil to be the tail end of the coil of the rapidly cooled extremely thin metallic band sheet fed to the winding machine just before finishing the coil winding. CONSTITUTION:When the extremely thin rapid cooled thin band W is wound by a reel 31, as the coil W1 becomes near a prescribed coil diameter, the coil W1 contacts with pressure roll 4 to press the rapid cooled thin band W to the coil W1 by energizing force of the spring 5. Then, an injection nozzle 1 is approached on the upper surface of the thin band W by a hydraulic cylinder 3, an adhesive liquid is injected to apply on the surface of the thin band W. When the coil becomes to be the prescribed coil diameter and cut by the cutting machine 32, the tail end W2 of the cut coil is pushed on the coil W1 by the pressure roll 4 to adhere. Then, as the rotation of the coil W is stopped, immediately, the preventing treatment for coil loosening is performed. By this method, whirling of the tail end of the coil is eliminated and the tail end cracking is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for treating the tail end of a coil in a winding device for rapidly cooling ultra-thin metal strips.

<Prior art> A quenching ribbon casting machine that continuously supplies molten steel from the gap between a tandye dish equipped with a throttle nozzle and a cooling quarry at the most upstream side of the line and rapidly solidifies the steel at a rate of 1,600 to 2,000 m/miL, for example. The quenched ribbon W, for example, having a thickness of 20 to 30 mm, which is continuously cast at a high speed and fed, is cast by a reel 31 of a winder (not shown) as shown in FIG. 4(a). It is wound around the coil W1,
When the coil diameter reaches a predetermined value, the cutting machine 32 cuts the coil.

<Problems to be Solved by the Invention> In order to prevent changes in the material of the quenched ribbon W being cast, the quenched ribbon casting apparatus needs to maintain its casting speed constant. Therefore, the quenched ribbon W must be fed to the winding device downstream of the line at the high speed described above, and the reel 31 is rotated in synchronization with the feeding speed to wind it into the coil W1. There is a need.

However, the coil W1 was wound to a predetermined diameter and cut 8i3.
When winding is completed, the reel 31 and coil W1, which are rotating at high speed, must be stopped rapidly. Therefore, it is difficult to stop it immediately. Therefore, during the period from this cutting to the stopping ratio, the tail end W2 of the coil swings around, as shown by the two-dot chain line in Fig. There is 1Qlj!i that the tail end W2 cracks as it swings around.In addition, the winding loosens due to the centrifugal force of the coil W1 when it idles between cutting and stopping ratios, resulting in poor coil maintenance. There were some problems.

Therefore, the present invention provides a coil tail end processing method that prevents tail end cracking and deterioration of the winding condition.

Means for Solving the Problems> The present invention, which achieves the above-mentioned object, has the following advantages: When winding a rapidly cooled ultra-thin metal strip into a coil using a winding machine, immediately before winding of the coil is completed, the present invention An adhesive function is imparted to the surface of the ultra-thin quenched metal strip that comes into contact with the outer peripheral surface of the coil, which will become the coil tail end, and the cut coil tail end is attached to the coil tail end when the winding of the coil is completed. It is characterized by being fixed by adhesion to the outer peripheral surface.

Embodiments Here, embodiments of the method of the present invention will be described with reference to FIGS. 1 to 3. In FIG. 1, 1 is a cylindrical injection nozzle that is located between a reel 31 and a cutting machine 32, and this nozzle 1 is a quenched thin film that is wound into a coil W1 by a reel 31 of a winding machine (not shown). They are arranged in parallel to the header 2 over the entire width of the band W. header 2 is reel 3
The adhesive liquid supply device (not shown) is installed so as to be movable in a substantially perpendicular direction to the upper surface of the passing surface of the quenched ribbon W between the deflector roll 33 and the quenched ribbon W. is connected to. 3 is a hydraulic cylinder for advancing and retracting the head 2, and its rod end 3a is fixed to the header 2. Reference numeral 4 denotes a presser roller having a length that is almost the same as the width of the quenched ribbon W, and presses the coil W1 at the point where the quenched ribbon W supplied during winding contacts the coil W1, near the completion of winding the coil W1. The quenched ribbon W is disposed so as to freely rotate in contact with the coil W1, and is urged toward the reel 31 by a spring 5 so that the quenched ribbon W is tightly pressed against the coil W1. Reference numeral 32 denotes a cutting machine, which is disposed below the passing surface of the quenched ribbon W at an intermediate position between the injection nozzle 1 and the deflector roll 33.

In the structure shown in FIG. 1, for example, 1600 to 2
400m/Feeded at high speed like Hoi-Kyu, thickness is 20~
When an ultra-thin quenched ribbon W such as No. 307n is wound on the reel 31, when the coil W1 reaches a predetermined coil diameter, the coil W1 contacts the presser roll 4, and the presser roll 4 is The fed quenched ribbon W is pressed against the coil W1 by the biasing force of the spring 5. Then, the injection nozzle 1 is brought close to the upper surface of the quenched ribbon W by the hydraulic cylinder 3, and the adhesive liquid is sprayed and applied to the surface of the quenched ribbon W just before winding. When the coil is cut, the cut coil tail @W2 is pressed against the coil W1 by the presser foot 4 and becomes sticky. And coil W
Immediately after the rotation of the coil stops, take measures to prevent the coil winding from loosening, such as banding. FIG. 2 shows a second configuration example for the method of the present invention, in which an adhesive roller 11 of approximately the same length as the width of the quenched ribbon W is placed above the passing surface of the quenched ribbon W.
While being pivoted to the rod end 13a of the hydraulic cylinder 13, a bearing roller 14 is rotatably disposed below the plate passing surface. The outer peripheral surface of the adhesive roller 11 is
As shown in FIGS. 3(a) and 3(b), a commercially available double-sided adhesive tape 12 made of wax paper 12b with a tape width of 50 m and double-sided adhesive paper 12a is placed in advance on a quenched RS band with a plate width of 100 m, for example. If it's W, wrap two strips side by side. Immediately before winding the coil W1, the pressure sensitive adhesive roller 11 is pressed against the quenched ribbon W by the hydraulic cylinder 13, and the double-sided adhesive paper 12a is pasted onto the quenched ribbon W as shown in FIG. 3(b). When the quenched ribbon W is peeled off from the wax paper 12b and simultaneously cut by the cutter 32, the tail end W2 of the coil is pressed against the coil W1 by the presser roller 4 and adheres to the coil W1 via the double-sided adhesive paper 12m.

<Effects of the Invention> As explained above, according to the present invention, an adhesive function is applied to the surface of the quenched ultra-thin metal strip supplied to the coil being wound, which is in contact with the outer peripheral surface of the coil, immediately before the winding is completed. By applying this, the cut coil tail end adheres to the outer circumferential surface of the coil when winding is completed, so even if the rotation of the rotating mechanical device such as the coil and reel does not stop immediately due to the inertia, the coil tail end will stick to the outer circumferential surface of the coil. There is no swinging around, no cracking at the tail end, and no loosening of the winding due to the centrifugal force of the rotation of the coil.
