DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a strip of metal or plastic on the exit side of a continuous line for continuously treating strip such as a stainless steel pickling line or a complete continuous tandem cold rolling line. operation of inserting the sheet between rubbing for flaw prevention is performed, and relates to a continuous supply how paper while you like can be continuously performed without stopping the line.

[0002]

2. Description of the Related Art Conventionally, when a strip, such as a cold-rolled stainless steel sheet, whose surface quality and surface gloss are regarded as important, is wound on the output side of the processing line, a slip sheet is inserted between the strip layers. Has been done. Here, the purpose of inserting the slip sheet between the strip layers is listed as follows. (1) When the strip is wound, it is prevented that the strip is rubbed and scratches are generated on the surface. (2) When the wound coil is transported to the next step or a coil storage area, the coil is prevented from being loosened and the strips from being rubbed against each other to generate scratches. (3) In the next step, when the coil is rewound and passed, the strip is prevented from rubbing to prevent scratches on the surface. (4) When the processing line is, for example, a rolling mill, if the wiping of the rolling oil is insufficient, the strip may laterally shift due to the remaining rolling oil during winding.
Excess rolling oil is absorbed by the slip sheet to prevent lateral displacement. (5) Particularly in the case of rolling a stainless steel plate, for example, after performing high-speed rolling to an intermediate thickness using a high-viscosity rolling oil with a large-capacity tandem rolling mill, use a small-diameter roll rolling mill to remove a low-viscosity rolling oil. There is a process of using the finish rolling to the product thickness. During the tandem rolling, if oil pits are formed on the plate surface and high-viscosity rolling oil remains in the pits, the oil enclosed in the pits will prevent crushing of the pits during the next rolling with a small-diameter roll. However, it may adversely affect the surface properties of the final product. Therefore, a slip sheet is inserted on the tandem mill exit side, and high viscosity rolling oil remaining in the oil pit is absorbed and removed by the slip sheet.

As a conventional example for supplying a slip sheet to a strip winding device for the above purpose, for example, FIG.
0 is known, and its improvement is described in JP-A-1-133611 and JP-A-3-161.
118, Japanese Patent Application Laid-Open No. 3-161119 and the like have made various proposals. FIG. 20 schematically shows equipment on the exit side of a metal strip processing line. A metal strip m that has been subjected to rolling, annealing, pickling, etc., passes through a deflector roll 1 and a take-up reel 2. And become the coil 3. At that time, a slip sheet p is inserted between the already wound metal strip and the metal strip wound around the outside. That is, the slip sheet p unwound from the slip sheet coil 4 by the slip sheet unwinder 5 of the slip sheet supply device.
Is inserted between the layers of the coil 3 of the metal strip m and wound up together with the metal strip m.

When the coil 3 of the metal strip m wound up together with the slip sheet p has a predetermined size, the line is temporarily stopped. Then, the metal strip m is cut by the shear 6, and the slip sheet p is also cut by a cutter knife or the like. Next, the coil 3 around which the slip sheet p and the metal strip m are wound and wound is extracted from the winding device by the coil car 7. After that, the low-speed operation of the line is resumed, and the leading end of the succeeding strip m is wound around the newly set take-up reel 2 while simultaneously winding the leading end of the slip sheet p.

On the other hand, Japanese Patent Laid-Open Publication No.
Fig. 20 shows a slip-sheet coil 4 and a metal strip coil 3
A proposal is made to prevent vertical wrinkles on the slip sheet p from being transferred to the metal strip m and impairing the surface quality between the slip sheet p and the slip sheet p from the slip sheet coil 4 to the coil 3 of the metal strip. A plurality of guide rolls are used on the travel path of the present embodiment, and the non-contact travel distance of the slip sheet p is shortened as much as possible.

Japanese Unexamined Patent Publication No. Hei 3-161118 discloses that a plurality of guide rolls provided on the traveling path of the slip sheet p guide the leading end of the slip sheet p to the insertion point as described above. This is a proposal to be performed without using. That is, a large number of ventilation holes are provided on the roll surface of the guide roll close to the slip-sheet coil, the guide roll is initially set to a negative pressure to suction the end of the slip-sheet, and the guide roll is moved to just above the slip-sheet insertion point Then, the guide roll is pressurized to blow out air from the air holes, and the leading end thereof is lowered to the insertion point while feeding the slip sheet, and the guide sheet is wound.

Japanese Patent Application Laid-Open No. Hei 3-161119 discloses FIG.
When the strip m is cut by the shear 6, the cut end of the strip is wound and passes through the uppermost portion of the coil 3, and then falls from the top to the bottom while being swung by the centrifugal force away from the outer periphery of the coil 3. Therefore, the interleaving sheet p is cut, and the interleaving sheet coil 4 is not taken into consideration because the interleaving sheet p cannot be further wound several times around the outer periphery of the coil.
A variable-position deflector roll for adjusting the slip-sheet tension is disposed between the strip-winding reel 2 and the strip take-up reel 2, thereby preventing cutting of the slip-sheet due to dropping of the coil end and thus enabling additional winding of the slip-sheet. It is what it was.

[0008]

However, in the above conventional example, when the remaining length of the slip-sheet coil 4 is exhausted, or when the width of the slip-sheet p is changed in accordance with the width change of the metal strip m. After removing the slip-sheet coil 4 from the slip-sheet unwinder 5, a new slip-sheet coil 4 is mounted on the slip-sheet unwinder 5, and the leading end of the slip sheet p is guided to the take-up reel 2 of the winding device. Needed. During this operation, the interleaving sheet p cannot be supplied, so that the line must be stopped and the efficiency is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. In a winding device on the output side of a continuous strip processing line, division of a slip sheet and renewal of a new sheet without stopping the line are performed. and to provide a slip-sheet continuous supply how capable width changing switching and between paper into the paper coil.

Next, a method of supplying a slip sheet p to the winding device 8 by the continuous slip sheet supply device 10 having the above-described configuration will be described with reference to FIGS. 1 and 4 to 9. In FIG.
Strip m rolled by a complete continuous tandem rolling mill
The traveling direction is changed by the deflector roll 1 on the exit side of the rolling mill, and the deflector roll 1 is being wound on one winding reel 2 b of the winding device 8. At the same time, the slip-sheet p discharged from the pay-out slip coil 14a of the continuous-sheet feed device 10 is supplied to the take-up reel 2b of the take-up device 8 with its traveling direction changed by the slip-sheet deflector 15, and the strip m Coil 3
And being wound up with the strip m.

During the winding of the strip m and the slip-sheet p, the pay-out slip-sheet coil 1 in the slip-sheet continuous feeding device 10 is used.
When the remaining length of 4a is lost or when the width of the slip sheet p is changed in accordance with the width change of the strip m, the slip sheet connection to the copy slip coil 14b is performed according to the procedure shown in FIGS. . The rotation in the rewinding direction of the standby-side sheet unwinder 12b is accelerated until the peripheral speed of the shaft rotation of the copy slip-sheet coil 14b becomes equal to the pay-out speed of the pay-out slip coil 14a (FIG. 4).

When the adhesive 20 previously attached to the surface of the slip-sheet coil 14b passes immediately below the slip-sheet connecting roll 18c of the slip-sheet connecting device 18, the slip-sheet connecting roll 18c is held down. It is pressed against the surface of the slip-sheet coil 14b. As a result, the slip sheet p during the paying-out travel has its back surface pressed against the adhesive material 20 to be connected to the copy slip coil 14b (FIG. 5).

Immediately thereafter, the slip-sheet cutter 19 moves forward to cut the slip-sheet p discharged from the discharge-sheet coil 14a. Thereafter, a new slip sheet p which has been discharged from the copy slip coil 14b is supplied to the winding device 8 (FIG. 6). Thereafter, the paying-side interleaving paper unwinder 12a rotates in the direction opposite to the direction during the paying, and winds the cut remaining interleaving paper p '. Also, the slip-sheet connecting roll 18c of the slip-sheet connecting device 18
And the slip-sheet cutter 19 retreats (FIG. 7).

The dispensing slip-sheet coil 14a having no remaining slip-sheet length is removed from the dispensing-side slip-sheet unwinder 12a, and a new slip-sheet coil 14c is mounted as a copy for the next cycle. The slip sheet connecting device 18 is retracted when the swing arm 18a rotates upward (FIG. 8). Thereafter, the slip-sheet unwinder 11 is revolved around the rotation axis 11a in the counterclockwise direction in FIG. 9, and the positions of the slip-sheet coil 14b which has been in the reserve position and the newly-installed slip-sheet coil 14c are exchanged. , And returns to the state of FIG. 1 (FIG. 9).

Thus, the continuous sheet feeding device 1 according to the present embodiment
If 0 is used, even when the remaining amount of the interleaving coil 14a is exhausted, or when the interleaving width is changed during the interleaving, the interleaving of the interleaving sheet and the new interleaving coil can be performed without stopping the line. Can be changed and the width of the slip sheet can be changed.
The effect that the operation rate of the line is much improved than before is obtained. In the above-described embodiment, the interleaving sheet continuous supply device 10 is described as having an interleaving sheet unwinder having two axes of the paying-side interleaving sheet unwinder 12a and the standby-side interleaving sheet unwinder 12b. Has the same effect.

Next, a method of dividing the slip sheet p, which is performed in accordance with the division of the strip m in the strip processing line, and inserting the leading end of the divided slip sheet into the take-up reel 2a of the winding device 8 will be described. The division of the strip m and the slip sheet p is as follows. In the rolling mill which is the continuous strip processing line of FIG.
The position of the dividing point is tracked by, for example, detecting a strip traveling distance obtained by counting the number of rotations of a rolling roll. The tracked position information of the division point M is transmitted to the running shear 9 of the rolling mill and the slip sheet cutter 16 on the output side of the slip sheet deflector 15 via the control system.
Are input to respective driving devices (not shown).

The cutting of the slip sheet by the slip sheet cutter 16 is started when the dividing point M of the strip m reaches a predetermined distance range set before (front) or behind the runway shear 9. This is performed by rotating the paper cutter 16. On the other hand, the cutting of the strip m is performed by rotating and driving the running shear 9 when the dividing point M passes through the running shear 9. By cutting the slip sheet p and the strip m by such a method, it is possible to align the length of the strip m and the slip sheet p within a certain range and wind the strip m and the strip m on the strip winding device 8. The coil 3 of the strip m wound on the strip take-up reel 2b together with the slip sheet p is pulled out from the take-up reel 2b by the coil car 7 and carried out.

The insertion of the new strip m and the slip sheet p into the take-up reel 2a is as follows. After the strip m and the slip sheet p are divided by the above-described method, the winding reel 2a in the standby state is rotated in the winding direction with the belt wrapper 8A wound thereon without stopping the strip processing line, The slip sheet p is sent out from the slip sheet continuous supply device 10. At this time, the rotation of the pay-out side sheet unwinder 12a is set so that the feed speed of the slip sheet p is equal to the line speed of the strip m or a speed having a constant advance rate with respect to the line speed of the strip m. Control the speed. The leading end of the slip sheet p is sent out by the slip sheet deflector 15 toward the strip take-up reel 2a, is inserted between the take-up reel 2a and the belt wrapper 8A together with the strip m, and is taken up by the take-up reel 2a. After the winding has been performed to some extent, the belt wrapper 8A is opened and retracted downward while the winding is continued, and the winding device 8 is moved counterclockwise in the figure by 180 degrees.
Revolve degrees. As a result, the take-up reel 2a, which is being wound, moves to the steady take-up position and changes position with the previous take-up reel 2b. At the same time, the previous take-up reel 2b moves to the position. A belt wrapper 8A is wound around the take-up reel 2b to prepare for the work of winding the leading end of the strip m and the slip sheet p to be cut next time.

Next, a method of changing the width of the slip sheet p according to the change of the width of the strip m will be described. In FIG. 1, it is assumed that the slip-sheet coil 14b is wound with a slip-sheet p corresponding to the sheet width of the strip m after the sheet width is changed. Now, the strip width change point M of the strip m is the deflector roll 1
And the distance reaching the strip take-up reel 2b via the slip-sheet connecting device 18, the slip-sheet p supplied from the slip-sheet connecting device 18
8c is started, and when the distance reaches the strip take-up reel 2b via the slip-sheet deflector 15,
According to the procedure of the slip sheet connecting operation shown with reference to FIGS. Is performed to switch the width of the slip sheet p to be supplied. As a result, the changed width of the strip m and the width and length of the interleaf supplied to the strip m are matched with each other to take up the reel 2b.
It is possible to wind up.

Next, reference examples not included in the scope of the present invention will be described.
This will be described with reference to FIGS. Reference example The interleaf continuous feeding device 10 is of a type in which the interleaf unwinder 11 does not revolve, that is, the payout side interleaf unwinder 12a.

Together with the pinch rolls 25a and 25b as a paper holding device, they are configured to be horizontally movable integrally. In the meantime, the paper connection method is as follows.

When the remaining length of the payout side interleaf unwinder 12a is exhausted, the rotation of the pinch rolls 25a and 25b is stopped, and at the same time, the interleaf cutter 19 is operated to cut the interleaf p (FIG. 10). Subsequently, the pinch rolls 25a and 25b, which hold the tail end of the divided slip sheet p, are attached to the standby slip sheet coil 1 attached to the standby-side slip sheet unwinder 12b.
4b (FIG. 11). Then, when the adhesive 20 of the copy slip coil 14b passes directly below the slip-sheet connecting roll 18c, the slip-sheet p is pressed and connected (FIG. 1).
2). As a result, the slip sheet p discharged from the standby-side slip sheet unwinder 12b is supplied to the winding device, and the slip sheet supply is continued. Next, the slip-sheet connecting device 18, the slip-sheet cutter 19, and the pinch rolls 25a and 25b are moved in the opposite directions and returned to their original positions. At this time, the lower pinch roll 25a has already paid out the slip-sheet. The sheet coil 14b is returned to the original position while bypassing the outer periphery of the sheet coil 14b during the operation. Further, a new slip-sheet coil 14c is mounted on the payout-side slip-sheet unwinder 12a (FIG. 13).

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, a continuous-sheet feeding device 10 includes a single-axis slip-sheet unwinder 12 disposed above a strip winding device 8 and a slip-sheet connecting roll 18c driven forward and backward by an air cylinder 18d. 18, a slip-sheet cutter 19 driven forward and backward by an air cylinder 19a,
