An insert unwinder is provided, and the insert unwinder is configured to be capable of pressing or separating from the metal plate on the deflect roll, and the insert unwinder with respect to the deflect roll. The peripheral speed of the insert is synchronized with the feed speed of the metal plate while being pressed or separated.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows an embodiment applied to a rolling facility having a reversible rolling mill 1. In the figure, 2'is an unwinder for unwinding a metal plate 5,
3'denotes a deflecting roll for guiding the metal plate 5 unwound by the unwinder 2 ', and 4'denotes an intermediate paper reel for winding the intermediate paper 7'. The unwinder 2 ′ for unwinding the metal plate 5 unwinds the coil 6 ′ formed by including the intermediate paper 7 ′ between the layers of the metal plate 5. When the intermediate sheet 7 '(shown by a dotted line) on the metal plate 5 is unwound to the vicinity of the deflector roll 3', the intermediate sheet winding device 11 'for the intermediate sheet reel 4'is provided.
Then, only the intermediate paper 7'is separated from the metal plate 5 and wound around the winding drum of the intermediate paper reel 4 '.

Therefore, only the metal plate 5 is supplied to the rolling mill 1 and rolling is performed. The intermediate paper reel 4'is supported by a support arm 12 'on a stand of the rolling mill main body, and is configured so that it can be pressed against the deflecting roll 3'or released upward by a cylinder 8'. In this way, the peripheral speed of the intermediate paper 7'can be synchronized with the feeding speed of the metal plate 5 by pressing or separating the intermediate paper reel 4'on the metal plate 5 on the deflector roll 3 '.

The metal plate 5 rolled by the rolling machine 1 is rewound by the winding machine 2 and at the same time, the intermediate paper 7 is supplied from the intermediate paper reel 4 on the deflector roll 3 installed on the delivery side of the rolling machine to receive the metal plate 5. Riding on the upper surface of the intermediate sheet winding device 11 between the layers of the metal plate 5
Thus, the coil 6 is formed while inserting the intermediate paper 7.

The intermediate paper reel 4 is also configured to be pressed against or separated from the metal plate 5 on the deflate roll 3 like the intermediate paper reel 4 ', and the peripheral speed of the intermediate paper 7 is set to the metal plate 5.
Can be tuned to the feed rate of.

Here, the pressing position of the intermediate paper reels 4 ', 4 should be immediately pressed on the deflector rolls 3', 3 holding the metal plate 5 or on the coils 6 ', 6 itself.

Further, the ratio of the outer diameter to the inner diameter of the intermediate paper reels 4 ', 4 is usually 3
There is about 10th place, the bearing of the intermediate paper winding cylinder is a rolling bearing, the rolling resistance is small and the friction coefficient of the outer diameter of the coil between the metal plate and the intermediate paper is large, so the pressing force is small, but the intermediate paper reels 4 ', 4 Since it may be difficult to rotate due to flatness or the like, it is preferable to auxiliary drive the winding drum of the intermediate paper reels 4 ', 4 by a pneumatic motor or the like. (In the figure, 9 and 9'show auxiliary motors, 10 and 10 'show universal joints.) Next, control for pressing or separating the intermediate paper reels 4'and 4 from the deflector rolls 3'and the metal plate 5 on them. The method will be described.

For example, the tachometers 13 ', 13 calculate changes in the intermediate paper reels 4', 4 and the deflector rolls 3 ', 3' depending on the diameters of the intermediate papers 7 ', 7 of the intermediate paper reels 4', 4 '. It is sufficient to control the pressure of the pressing cylinders 8 ', 8 against. That is, it is preferable that the pressing force of the intermediate paper reels 4'and 4 be made smaller as the outer diameter of the intermediate paper reels 4'and 4 becomes larger.

Further, the above-mentioned intermediate paper wrapping device 11 ', 11 may be an automatic system using an adhesive spraying device or an adhesive tape sticking device, or may be a simple manual device only at the beginning to catch the leading edge of the intermediate paper. .

In the above description, only the case where the pass direction of the metal plate 5 advances from right to left in FIG. 1 has been described, but when the rolling mill 1 is a reversible type, the pass direction of the metal plate 5 is changed from left to right in the next pass. It will proceed to the right, and in this case, the unwinder 2 '
Is a winder, the winder 2 is a winder, the intermediate paper reel 4 winds up the intermediate paper 7 inserted between the layers of the metal plate 5 forming the coil 6, and the intermediate paper reel 4'is Rolling machine 1
The coil 6 is formed while inserting the intermediate paper 7 between the layers of the metal plate 5 rolled by.

According to the embodiments of the present invention described above, 1) the intermediate paper reels 4 and 4'are attached to the deflector rolls 3 and 3 '.
Since the metal sheet 5 is pressed against the intermediate sheet 7,
Since 7'is unwound or wound at the same speed as the metal plate 5, there is no fear of running out of paper.

2) Since the intermediate papers 7 and 7'are unwound or rolled up on the surface of the metal plate 5, "wrinkles" do not get on the intermediate papers 7 and 7 '.

3) The metal plate 5 is also used when unwinding or winding up the intermediate paper 7, 7 '.
Since the intermediate papers 7 and 7'come on the surface of, it can be wound at a low position. (The position of the deflector rolls 3 and 3'is usually about 1 meter from the work floor.) 4) The intermediate rolls 4 and 4'are attached to the deflector rolls 3 and 3 '.
By pressing the metal sheet 5 against the deflector rolls 3 and 3 ', a frictional force is exerted between the deflector rolls 3 and 3'and the deflector rolls 3 and 3'become easy to rotate, so that the deflector rolls 3 and 3'are easily rotated. The risk of slip between rolls 3 and 3'is also reduced.

In addition to the above performance and efficiency improvement, 5) Since the intermediate paper reels 4 and 4'are driven by the transfer of the metal plate 5, they are driven. Moreover, since there is no worry of running out of paper, a simple motor, such as a pneumatic motor, is sufficient, resulting in a significant cost reduction.

〔The invention's effect〕
