Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for cutting and immediately winding rapidly cooled ultra-thin metal strips onto a reel of a winding device.

<Prior art> Conventionally, when winding a thin strip steel having a thickness of 0.5 to 1.0 nm into a coil using a winding machine, the winding on the reel at the start of winding is carried out using a belt wrapper or the like. A device is used for winding. In addition, a cutting device such as a tram shear is used upstream of the winding machine for cutting during rewinding to continuously wind the ribbon steel on two reels.

<Problems to be Solved by the Invention> However, the above-mentioned conventional method uses a quenched ribbon that is extremely thin and extremely brittle, such as a thickness of 20 to 30 μm, and is fed at an ultrahigh speed of, for example, 1600 to 2400 m/mtn. The cutting device and winding of the quenched ribbon is very thin and is fed at extremely high speed, so if you try to cut it with the device and wind the tip onto another reel, it will take a short time. This was extremely difficult.

The present invention is a gold W that runs at high speed! 4 An object of the present invention is to provide a cutting device for winding an ultra-thin strip, which can cut the ultra-thin strip while maintaining its running speed, and which can immediately start winding.

Means for Solving the Problems> The present invention has a structure in which an ultra-thin metal strip is continuously wound into a coil shape using a plurality of reels, and the winding of the reels is performed at a certain position. A revolution disk is installed which rotates around an axis eccentric from the axis of the reel and is movable parallel to the axial direction of the reel, and a winding roller and an idle roller are rotatably attached to the revolution disk. Also,
The present invention is characterized in that a strip cutting machine is installed close to the winding roller.

<Function> One reel is moved to the winding position and the other reel is placed on standby, and further below the winding position, the ultra-thin metal strip is fed from the upstream side of the feeding line to the downstream side. do.

Then, the revolution disk is brought close to the winding device, and the winding roller and idle roller are aligned with the one reel below the ultra-thin metal strip. Thereafter, by rotating the revolution disk, the ultra-thin metal strip is pushed up from below by the winding roller and the idle roller and wound around the one reel, and this reel is also rotated at high speed. Here, since the revolving disc is eccentric with respect to the axis of one reel at the winding position, when the revolving disc is rotated, the winding roller etc. revolves so as to approach the reel on the negative side. That will happen. Therefore, when an ultra-thin metal strip is wound around the entire circumference of one reel using a winding roller, the ultra-thin metal strip is cut by a strip cutting machine near the winding roller, and the cut ultra-thin metal strip is cut. The tip of the plate is held between the winding roller and the one reel and wound. When the winding is completed, the revolution disk is separated from the winding device and the one reel continues winding the ultra-thin metal strip. When winding is complete,
Swapping the one reel and the other reel,
An ultra-thin metal strip is wound around the other reel according to the procedure described above. Thereafter, the same procedure is repeated to continuously wind the material into a coil shape onto a plurality of reels.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1 to 7.

As shown in the figure, the winder C is of the carrousel type. That is, two reels 22a and 22b are supported horizontally on the revolving drum 21, and are rotated by a drive device not shown in the figure. When the revolving drum 21 is rotated, the reels 22 m and 22 b can be moved to the winding position or the standby position.

For example, the winding position of the reel 22a indicated by the two-dot chain line in FIG. 2 is indicated.

In order to feed the ultra-thin metal strip W to the winder C, the reel 2
Rails 19 are laid on the floor below 2 a and 22 b, and a self-propelled cart 18 moves on the rails 19.
is provided to constitute the tip gripping machine B. here,
A drive device 17 is installed upright on the self-propelled cart 18, and the drive device 17 is provided with pinch rollers 16a and 16b for gripping the tip of the ultra-thin metal strip W. The upper pinch roller 16m is attached to a drive value M17 so as to be movable up and down. The ultra-thin metal strip W has a thickness of, for example, 20 mm.
It is extremely thin like ~30μm, for example 2000ffl
The quenched sheet is fed at a high speed such as /1 m I n.

Furthermore, in the winding of the present invention, the cutting iA is provided on the side of the winding machine C. That is, a self-propelled cart 12 is movably placed on rails 13 laid on the floor, and the revolution IJ11 is supported by the self-propelled cart 12 via a drive value [111]. By running, the revolution disk 1 can be moved parallel to the reels 22a and 22b. Furthermore, this revolution disk 1 can be rotated by a drive device 11, and its center is the reel 22a at which the winding is performed.

It is located eccentrically from the axis of 22b. A bearing block 3 is fixed to the revolution disk 1 via a support plate 2, and between this bearing block 3 and the revolution disk 1, a winding roller 4 and an idle roller 5°6.6 are pivotally attached. . Winding roller 4
contacts the ultra-thin metal strip W in advance, and the reel 22a.

It revolves so as to be close to 22b. In addition, the idle rollers 5, 6, 6 are moved to the metal ultra-thin strip W later than the winding roller 4.
The winding roller 4 comes into contact with the winding roller 4 and assists the winding roller 4. A cutting blade 7 is mounted on the support plate 2 via a hydraulic cylinder 8 as close as possible to the winding roller 4.

The winding and cutting machine A of this embodiment having the above configuration is used as follows.

First, as shown in FIG. 2, both reels 22a and 22b
are retracted from each other to a horizontal position to allow the tip gripping machine B to pass through, and the fed metal pole r4 strip W is gripped by the pinch rollers 16a and 16b at the position shown by the two-dot chain line in the figure. It is moved to the center left by the self-propelled trolley 18.

Next, the revolving drum 21 is rotated to move the reel 22a to the winding position indicated by the two-dot chain line and move the reel 22b to the standby position indicated by the two-dot chain line. At the same time, for winding, the cutting iA is moved by its self-propelled cart 12 on the rail 13 toward the winding machine C, and the winding roller 4 and idle rollers 5, 6.6 are placed below the ultra-thin metal strip W to reel it. 22a in parallel.

Then, as shown in FIG. 3, the revolution plate 1 is rotated to cause the winding roller 4 and the idle roller 5 to revolve at an angle of 6.6 degrees, and the ultra-thin metal strip W is pushed up from below and wound around the reel 22a.

Here, the center of the revolution disk 1 is the reel 22 at the winding position.
Since it is eccentric from the axis of a, the rotation of the revolution disk 21 causes the winding roller 4 to revolve so as to approach the reel 22a. Furthermore, while the reel 22a is rotated at high speed, the winding roller 4 and the idle rollers 5, 6, . 6
After rotating, the hydraulic cylinder 8 presses the cutting blade 7 against the ultra-thin metal strip W that is wound around the loop 22 (L), cuts it, and immediately pulls it back. The leading end of the winding roller 4 and the reel 22a are held between the winding roller 4 and the reel 22a, and are wound onto the reel 22a.When the winding starts, the self-propelled cart 12 is moved backward and the winding roller 4 and the idle rollers 5j 6, 6 are rolled up. It is pulled away from the winder C. The strip W1 in front of the cut point is moved to the left in the figure by the tip gripper B, removed from the pinch rollers 16a and 16b, and discarded.

After that, one reel 22a is used to release the gold m8ii thin strip W.
While winding up the reel 22, the revolving drum is rotated and the winding position is gradually moved to the left in the figure.
Wrapping b moves it to the position. When the ultra-thin metal strip W approaches a predetermined coil diameter, as shown in FIG. Move it to the bottom. Then, the self-propelled cart 12 is moved forward to be parallel to the reel 22b below the ultra-thin metal strip W. Thereafter, as shown in FIGS. 6 and 7, the revolution plate 1 is rotated, and the winding roller 4 and idle rollers 5 and 6.6 push up the gold and thin strip sheet metal, and reel as described above. 22b, cut by the cutting blade 7, and connected to perform rewinding. The strip W in front of the cutting point is wound up by one reel 2211 as the tail end of a coil. The coil wound around the coil 22a is extracted and conveyed to the next process.

Thereafter, the above-described rewinding is repeated to continuously wind up the metal pole r4 strip W.

<Effects of the Invention> Above all, as specifically explained based on the examples, the present invention rotates the winding roller eccentrically with respect to the reel to wind the ultra-thin metal strip. Since the metal strip is cut, it is possible to rewind the ultra-thin metal strip while it is running at high speed while maintaining the running speed, and furthermore, winding can be started immediately after cutting.
