Description

The present invention relates to a device for winding a rapidly cast metal, which has a high mechanical strength, has a low elastic strain limit, and is easily bent and deformed. The present invention relates to a winding device suitable for multi-strand ribbons, multi-strand wires and the like.

[Conventional technology]

Conventionally, many methods have been proposed for winding a rapidly cast metal. For example, the present inventor previously proposed a method of winding a dummy sheet around a magnetic roll while sandwiching a quenched metal to start winding. Further, JP-A-55-70414 and JP-A-57-94453 propose a method of directly winding a quenched metal on a magnetic roll.

However, in the method using a dummy sheet, the mechanical strength is high, the elastic strain limit is low, and the quenching metal that is easily bent and deformed does not deform the metal and does not adhere to the dummy sheet. However, since it is difficult to wind, it has been difficult for the conventional winding method to reliably capture the rapidly-quenched metal of the above-mentioned material that runs at high speed.

[Problems to be solved by the invention]

In order to solve the above-mentioned conventional problems, an object of the present invention is to provide a quenching metal winding device which has high mechanical strength, low elastic strain limit, and is suitable for quenching metal which is easily bent and deformed. is there.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a rotary cylinder having a plurality of openings on its circumferential surface, and a rotary cylinder provided inside the cylindrical rotary body and provided parallel to the rotation axis direction of the rotary cylinder. A rotary reel having a frame provided with a plurality of strips in a direction parallel to the rotation axis on a shaft, and the rotary reel is provided with the strips parallel to the frame. The outer peripheral surface of the rotating cylindrical body protruding outward from the opening of the rotating cylindrical body, and the winding of the quenched metal provided with a gap between the rotating outer peripheral surface and the opening of the rotating cylindrical body. A picking device is provided.

The present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the outer surface of the entire apparatus, and FIG. 2 is a side sectional view.

The winding device body 2 includes a rotary cylinder 5 having a plurality of openings 4 on a circumferential surface 3, and a rotary shaft center 11 provided in parallel with the rotary shaft 6 direction of the rotary cylinder 5. It comprises a rotary reel 8 for pinching, which is provided with a frame 13 (FIG. 4) having a plurality of strips 7 parallel to the core 11. The rotating reel 8 is arranged inside the rotating cylindrical body, and the parallel strip 7 of the frame forms a rotating outer peripheral surface by the rotation of the rotating reel 8, and this rotating outer peripheral surface is the opening of the rotating cylindrical body 5. It is disposed so as to project outward from the portion 4, and a gap 10 (FIG. 2) is provided between the rotation outer peripheral surface of the rotation reel 8 and the opening 4 of the rotation cylinder. There is.

By the way, the length in the rotation direction of the cylindrical body of the opening portion 4 of the rotating cylindrical body 5 may be determined by the degree of protrusion of the strip forming the outer peripheral surface of rotation of the rotating reel 8, but at least the frame body of the rotating reel. It is preferable that the protruding amount from the opening having a diameter equal to or larger than the diameter of the strip 7 and the maximum extent of the protruding amount be less than the radius of the reel because the rotating reel is provided inside the rotating cylindrical body. For example, if the diameter (thickness) of the strip material of the frame of the rotating reel is a and the diameter of the reel is b, the length of the opening in the rotation direction is 2 (ab-a ² ) ^1/2 or more, b Is less than.

On the other hand, it may be determined according to the length of the opening 4 in the width direction of the cylindrical body and the width of the quenched metal to be manufactured. preferable. Naturally, the strip 7 of the frame body of the rotating reel
The length of may be determined according to this.

As described above, since it is necessary to provide a gap between the opening and the outer peripheral surface of the reel, the size of the opening is determined in consideration of the gap in addition to the above.

Next, a method of winding the quenched metal by using such an apparatus will be described together with its action mainly with reference to FIG.

After the quenched metal foil strip 1 is separated from the casting roll, it is assumed that the quenched metal foil strip 1 proceeds to the left as indicated by the arrow. A plurality of pinching rotary reels 8 are arranged in the winding device body 2 at the circumferential opening 4 of the rotary cylinder 5. The rotating cylinder 5 is rotating at a peripheral speed equal to the speed of the quenched metal 1. In this example, the pinching rotary reel 8 has a pinching strip 7 parallel to the rotation axis direction.
The frame 13 arranged in two places rotates at a peripheral speed twice or more the speed of the quenched metal 1.

In this way, the quenched metal 1 conveyed to the winding device in a state in which the rotary cylinder 5 and the sandwiching rotary reel 8 are both rotating is such that a part of the circumferential surface 3 of the rotary cylinder is partly indicated by a broken line. It is sandwiched in the gap 10 between the plate 9 between the formed openings and the strip 7 of the frame forming the rotating outer peripheral surface of the sandwiching rotary reel 8. On the other hand, since the rotating cylindrical body 5 is rotating at high speed, the winding is instantly started.

In addition, as shown in FIG. 3, reverse hairs 12 made of metal or the like are planted on the surface of the plate 9 between the openings with respect to the rotating strip 7 so that the quenched metal 1 which is once sandwiched does not easily come off. You can leave it. After the start of winding, the rotation of the pinching rotary reel 8 may be stopped.

In addition, the number of the pinching rotary reels 8 is equal to that of the rotary cylinders 5.
In order to make the circumferential surface 3 of the polygonal shape polygonal and smoothly match with the traveling speed of the quenched metal 1, it is desirable to have six or more, and as shown in FIG. (Fig. 2 shows eight).

Since it is desirable that the number of strips 7 of the frame body of the sandwiching rotary reel should be close to the plate 9 between the openings several times while the rotary cylinder 5 rotates 90 degrees, as shown in FIG. Two or more, preferably four or more.

For the same reason, the peripheral speed of rotation of the pinching rotary reel 8 is preferably twice or more the speed of the quenched metal 1.

The material of the strip 7 of the frame may be metal, but it is preferable to use heat-resistant rubber or the like on the surface of the strip 7 in order to increase the friction coefficient with the quenched metal.

Further, if a plurality of winding device bodies 2 are arranged in the carousel type continuous winding device, continuous winding is possible.

〔The invention's effect〕

When the apparatus of the present invention is used, even if the shape of the quenched metal is bad, the pinching and winding can be easily started regardless of the magnetism of the quenched metal. Therefore, it can be easily applied to a quenched metal that has a high mechanical strength, a low elastic strain limit, and is easily bent and deformed.
