Description

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

<Prior art> A quenching ribbon casting machine that continuously supplies molten steel from the gap between a tundish with a slot nozzle and a cooling roll at the most upstream side of a line and rapidly solidifies the molten steel at a speed of 1,600 to 2,000 m/min, for example. Thickness that is continuously cast and fed at high speed
The quenched ribbon W of 20 to 30 μm is wound into a coil W1 by a reel 31 of a winding machine (not shown), as shown in FIG. 32.

<Problems to be Solved by the Invention> In order to prevent changes in the material of the quenched ribbon W to be cast, the quenched ribbon casting apparatus needs to maintain its casting speed constant. Therefore, the quenched ribbon W is also fed to the winding device downstream of the line at a high speed as 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, when the coil W1 is wound to a predetermined diameter and cut by the cutter 32 and the winding is completed, the reel 31 and the coil W1 rotating at high speed are cut off by the cutting machine 32.
It is necessary to stop the coil W quickly.
1. Due to the inertial force of the reel 31 and its rotating mechanical device (not shown), it is difficult to stop it immediately. Therefore, between this cutting and stopping,
As shown by the two-dot chain line in Fig. 4b, the coil tail end W
There is a problem in that the coil tail end W2 of the quenched ribbon W, which is made of an extremely thin and extremely brittle material, cracks at the tail end as it swings around.

In addition, the coil W1 has problems such as loosening of the winding due to the centrifugal force due to idle rotation between cutting and stopping, resulting in poor coil winding condition.

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

<Means for Solving the Problems> The present invention, which achieves the above-mentioned objects, provides a coil winding device for a thin metal strip, which includes a bearing block, an upper arm and a lower arm pivotally connected to the bearing block, and a coil winding device for a thin metal strip. an arm rotation device that rotates the upper arm and the lower arm; a fixed shaft fixed to the tip of the upper arm; an idle roller pivoted to the tip of the lower arm; and an idle roller pivoted to the bearing block. a belt winding shaft having a winding biasing force; a winding belt supported by the idle roller and having one end fixed to the belt winding shaft and the other end fixed to the fixed shaft; comprising a bearing block moving means that moves to wind the winding belt around a reel of a winding machine; and a strip cutting device provided on the opposite side of the bearing block moving means with the winding machine as the center. It is characterized by

<Operation> A rapidly cooled metal ultra-thin strip is wound into a coil by a reel of a winding machine, and just before the winding is completed, the upper arm is moved through the bearing block by the bearing block moving means. The lower arm and the winding belt are brought close to the coil being wound, the upper arm and the lower arm are rotated by an arm rotation device, and the coil is moved by the winding belt while leaving a strip feeding gap. Completely envelop. At this time, the winding belt is held at a predetermined tension by a torque applying device on the belt winding shaft, and is sliding on the outer peripheral surface of the rotating coil. Next, when the coil has reached a predetermined diameter and winding is completed, the quenched metal ultra-thin strip fed by the strip cutting device is cut, and the tail end of the coil in front of the cut section is attached to the winding belt. It slips between the winding belt and the outer periphery of the coil through the strip feeding gap, and is wrapped around the winding belt until the inertia of the coil and rotating mechanical devices such as the rails of the winding machine disappears and the rotation stops. while rotating.
When the rotation of the coil stops, the wrapping belt is returned to its original position to release its wrapping, and the coil winding loosening prevention treatment is immediately performed.

<Example> Here, an example of the present invention will be described with reference to FIGS. 1 to 3. 1 to 3, a self-propelled cart 25 moving on a rail 29 has a support plate 9 and a pair of bearing plates (bearing blocks) 8.
upper arms 1 are pivotally mounted to bearing plates 8a and 8b, respectively, and the upper arms 1 are connected to each other by beams 11 and 12. A lever 16 and a bracket 17 are fixed to the center of the beams 11 and 12. At the tip of the upper arm 1, a pair of tip arms 2 are each pivotally connected to each other by a beam 13 and a fixed shaft 4, and a lever 18 is fixed to the center of the beam 13. ing.

On the other hand, a lower arm 3 is pivotally attached to the bearing plates 8a and 8b, and the lower arm 3 is attached to the beam 14.
The idle rollers 5 are connected to each other, and an idle roller 5 is pivotally attached at the tip. And beam 1
A lever 19 is fixedly installed in the center of 4.

Further, a winding shaft 6 is mounted between the bearing plates 8a and 8b, and a torque motor 7 for driving the winding shaft 6 is mounted on one bearing plate 8a at one end of the winding shaft 6. is installed.

Further, the bearing plates 8a and 8b are interconnected not only by the support plate 9 but also by a beam 15, and brackets 20 and 21 are fixedly installed in the center of the beam 15.

It is pivoted between 20 and 20.

One end of the steel belt 10 is fixed to the fixed shaft 4, the center of the steel belt 10 is supported by the idle roller 5, and the other end of the steel belt 10 is fixed to the winding shaft 6, and when on standby, the steel belt 10 is fixed to the winding shaft 6.
It has been wound multiple times. A suitable tension is applied to the steel belt 10 by a torque motor 7.

To explain the operation in this configuration, an ultra-thin quenched ribbon W of, for example, 20 to 30 μm, which is fed from upstream of the line at a high speed of, for example, 1,600 to 2,400 m/min, is transferred to the coil W1 by the reel 31. When the coil W1 is wound up to a predetermined diameter, the self-propelled cart 25 is moved toward the coil W1 as shown in FIG. , the steel belt 10 is partially wound around the coil W1. The tension of the steel belt 10 is adjusted by the torque motor 7 so that it can slide freely even when the coil W1 is completely wound.

is rotated until the steel belt 10 wound around the fixed shaft 4 and the idle roller 5 comes into contact with the coil W1, and the coil W1 is completely moved by the steel belt 10, leaving a feeding gap for the quenched ribbon W. Wrap around. At this time, the winding shaft 6 rotates as shown by the arrow to unwind the steel belt 10 that has been wound therein. When the coil W1 reaches a predetermined diameter and the rapidly cooled ribbon W is cut by the cutter 32, the tail end W2 of the coil slips between the steel belt 10 and the outer periphery of the coil W1 and winds up. The steel belt 10 and the coil W1 continue to slide until the rotation due to the inertia of the coil W1, the reel 31, and its rotating device (not shown) completely stops. When the rotation of the coil W1 is stopped, the arms 1, 2, and 3 are rotated to return the steel belt 10 to its original position, and immediately the coil W1 is subjected to loosening prevention processing, such as banding. In addition, as an alternative to the steel belt 10, it has high wear resistance and toughness,
