Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for guiding both edges of a rear end portion of a strip near the completion of winding a metal strip (hereinafter referred to as a strip).

[0002]

2. Description of the Related Art FIG. 3 is a side view showing a concept of a terminal portion of a continuous pickling line as an example of a conventional strip winding device.

In the figure, the final processed strip S
The winder 80 through the deflector pinch roll 70.
Is wound around the mandrel reel 81 by a belt wrapper (not shown), and is wound around the coil C while being pressed by the snubber roll 86.

During winding, the position of the edge portion of the strip S is detected by the edge position controller 60, and the mandrel reel 81 is moved in the plate width direction according to the detected position so that the end surface of the coil C becomes flat. To control.

When the required weight of the coil C is reached and the winding is almost completed, the fed strip S is cut by the flying shear 50 arranged on the carrying line and is circumferentially contacted with the outer peripheral surface of the coil C. While the coil C is being pressed by the lower snubber roll 87 and the push-up roll 91 provided at the upper end of the coil car 90 disposed below the coil C, the cut portion of the strip S remains so that it is pressed by the push-up roll 91. After winding about 1.5 layers, the upper and lower snubber rolls 86, 87
The coil coil 9
0 is transported to the stockyard and banded.

The subsequent strip S cut by the flying shear 50 is continuously wound by another mandrel reel 82 in the same procedure as described above.

[0007]

The coil as a product is required to have smoothness on both end faces thereof. However, in the conventional device as described above, when the strip is cut by the flying shear on the transport line, the tension in the unwound portion of the strip almost disappears, and the cut portion becomes unconstrained and can be freely moved in the plate width direction. Therefore, the control by the edge position controller 60 becomes impossible.

Therefore, there is a problem that about 1.5 layers of the coil wound after cutting the strip are displaced in the plate width direction, and the shape (smoothness) of both end faces of the coil is deteriorated.

It is difficult to correct the protruding portion on the end surface of the coil due to the displacement in the plate width direction even if it is hit with a hammer manually.

It is an object of the present invention to provide a new side guide device for a winding machine that solves the above-mentioned problems.

[0011]

As a structure for achieving the above object, a side guide device for a winder according to the present invention is
In a device for winding a finally processed strip on a coil, a pair of tapered sides formed so as to be slidable in the width direction of the strip and having an outer diameter reduced toward the winding center of the coil. The guide rolls are rotatably arranged so that their outer peripheral surfaces are in contact with the outer peripheral surfaces of both end surfaces of the coil and the contact points between the strip lower surface,
A coil end surface pressing device is provided on each of the pair of side guide rolls.

[0012]

In the side guide device of the winding machine of the present invention, the peripheral surfaces of both side guide rolls are pressed against both end faces of the coil by the coil end surface pressing device immediately before the strip cutting for the completion of coil winding. Then, the strip is rotated together with the coil, and both edge portions of the strip, which has been cut at its rear end portion to become free, are guided and wound by both side guide rolls.

The strip up to the cutting is wound by an edge position controller so that both end surfaces of the coil are flat, and the strip after cutting is guided by side guide rolls, and both edges thereof are already wound. The coil is wound so that it is flush with both ends of the coil.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a side view showing a side guide device of a winder, and FIG. 2 is a partially cutaway view taken along the line II-II of FIG.

In these figures, for example, a strip S that is finally processed in a continuous pickling line and sent to a winder 80 is wound around a mandrel reel 81 by a belt wrapper (not shown) and rotated, so that a coil C is obtained. To be wound up.

Reference numeral 1 denotes a pair of side guide rollers arranged on the working side (W) and the driving side (D), and slips with the end faces of the coil C due to the difference in linear velocity at the positions in contact with both end faces of the coil C. In order to solve the problem, the outer diameter is formed in a tapered shape, and in the vicinity of a point where the outer circumference of the coil C and the lower surface of the strip S are in contact with each other, each outer frame is in contact with both end surfaces of the coil C. The shafts 3 are rotatably supported.

The frame 3 is slidably fitted to the rails 13 of the head 12 by the guide 4 and is connected to the air cylinders 6 juxtaposed to each other.
Is configured to move in the plate width direction.

Reference numeral 11 denotes an upper snubber roll, which is in contact with the outer peripheral surface of the coil C and is rotatably attached to the head 12.

The head 12 is pivotally attached to an arm 21 and rotated by a hydraulic cylinder 14. Further, the arm 21 is pivotally attached to a fixed stand 34, and the arm 21 is configured to rotate by a hydraulic cylinder 22.

Numeral 87 is a lower snubber roll, which is in contact with the outer peripheral surface of the coil C and is pivotally attached to the stand 34 by an arm 88.
Is rotatably attached to the shaft.

The winding machine 80 is equipped with a mandrel reel 81, and the strip S has the mandrel reel 81.
It is wound around and rotated and wound into a coil.

A coil car 90 is disposed below the coil C, and a push-up roll 91 is mounted on the upper part of the coil car so as to be vertically movable.

Next, the operation of the apparatus of this embodiment will be described. For example, the strip S, which is finally processed in the continuous pickling line and fed to the winder 80, is wound around the mandrel reel 81 by a belt wrapper (not shown). Attach and rotate, and wind around coil C.

During winding, each frame 3 is moved to the working side (W) and the driving side (D) so that the side guide rolls 1 are not in contact with both end faces of the coil C, and the arms 2 are in contact with each other.
1 is rotated by the hydraulic cylinder 22, and the head 12 is rotated by the hydraulic cylinder 14 to rotate the arm 21.
And the upper snubber roll 11 is pressed against the outer peripheral surface of the coil C.

The coil C is wound so that both end surfaces thereof become flat by detecting the position of the edge portion of the strip S by an edge position controller (not shown) and moving the mandrel reel 81 in the plate width direction.

As the winding progresses and the coil C becomes thicker as shown by the solid line in FIG. 1, the turning angles of the arm 21 and the head 12 are adjusted in accordance with the thickening of the coil C.
Adjust by 2,14.

When the coil C becomes close to the required weight and immediately before the strip S is cut on the conveying line by a flying shear (not shown), the lower snubber roll 87 and the push-up roll 91 are pressed against the coil C and both of them are pressed. The side guide rolls 1 are pressed against both end faces of the coil C by the respective air cylinders 6 with a predetermined air pressure.

The air pressure of each air cylinder 6 is configured to be switched to three stages of low pressure, medium pressure and high pressure by a switching valve (not shown). For example, when the thickness and strength of the strip S are large, the high pressure is set to high. Use, and use low pressure if smaller.

When the strip S is cut, its tension almost disappears, and the cut portion is unconstrained and freely swung in the plate width direction, so that control by the edge position controller (not shown) becomes impossible.

Therefore, both edge portions of the strip S are guided by the both side guide rolls 1 which are pressed against both end faces of the coil C and are rotating, and are made flush with both end faces of the coil C already wound. Wind up to become.

Even if the mandrel reel 81 and the coil C swing in the plate width direction during this time, the pressing force of each air cylinder 6 is smaller than the moving force of the mandrel reel 81.
Each side guide roll 1 moves according to the deflection of the coil C in the plate width direction.

Then, the winding is completed at a position where the cut portion of the strip S can be pressed and stopped by the push-up roll 91, and the coil C is moved to the coil car 90.
It is taken out from the mandrel reel 81 and conveyed to the stockyard.

If the coil C has a small diameter as shown by the two-dot chain line in FIG. 1, the side guide roll 1 and the snubber roll 1
1, 87 and the push-up roll 91 are moved as shown by the chain double-dashed line, and the strip S after cutting is wound up.

Further, as shown by the chain double-dashed line in FIG. 2, when the strip S has a narrow plate width, each frame 3 and the side guide rolls 1 are separated by the respective air cylinders 6 as shown by the chain double-dashed line. Move in the board width direction.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and it goes without saying that various design changes can be made within the scope of the technical idea of the present invention. ..
