For example, as shown in Figure 4, the picture signal that control device 30 receives from the first and second flexural measurement instrument 20 and 21.Based on input signals such as these picture signals, control device 30 is controlled first to the 6th vertical roller drivingly to drive unit 22a, 22b-27a, and 27b, and guided plate is to drive unit 28a, and 28b is pairing in pairs in a lateral direction.
Particularly, before connection, drive first and second vertical rollers to drive unit 22a, 22b, 23a, 23b makes the fore-end of back thin plate sheet 6 placed in the middle by first and second vertical rollers to 22 and 23.In this case, utilize the first flexural measurement instrument 20 to detect and measure the case of bending of back thin plate sheet 6.Equally, drive third and fourth vertical roller to drive unit 24a, 24b, 25a, 25b utilizes third and fourth vertical roller to make the rear end part of preceding thin plate sheet 9 placed in the middle to 24 and 25.In this case, utilize the second flexural measurement instrument 21 to detect and measure the case of bending of the rear end part of preceding thin plate sheet 9.For example, the position at the two ends by measuring broad ways, and obtain the center according to the position at the two ends of broad ways, thus measure.
For example, promptly the picture signal from the second flexural measurement instrument 20 and 21 inputs is carried out the image processing, so that the bending (state) of the rear end part of the bending (state) of the fore-end of detection and measurement back thin plate sheet 6 and preceding thin plate sheet 9.Based on these measurement results, calculate the bias δ f and the δ p (referring to Fig. 5 (a)) of center of the broad ways (referring to dotted line) at link position place along the direction of roll line.
Then, calculate the 4th and the 5th vertical roller, thereby make the bias δ of the center of broad ways 25 and 26 the amount of exercise that is used to regulate (the 3rd and the 6th vertical roller remains on the middle position to 24 and 27)
fAnd δ
pReduce, afterwards, the 4th and the 5th vertical roller is to drive unit 25a, and 25b, 26a and 26b move above-mentioned amount of exercise (referring to the arrow among Fig. 5 (b)), so that move the fore-end of back thin plate sheet 6 and the rear end part of preceding thin plate sheet 9 on width.In this case, need not many speeches, can only move the 4th and the 5th vertical roller one in 25 and 26 is regulated, thereby reduce the bias δ of the center of broad ways
fAnd δ
p
Then, the junctor 10 that the overlapping region of the fore-end of the rear end part of preceding thin plate sheet 9 and back thin plate sheet 6 is connected device 3 compresses, and pushes into so that connect from both sides, prunes simultaneously.Shown in Fig. 5 (c), in this case, carry out connection, there is not lateral run-out part (seeing also katakana イ and ロ in the accompanying drawing 7 (c)).
In the present embodiment, as mentioned above, in continuous (heat) rolling equipment, the overlapping region of the rear end part by compressing back fore-end of thin plate sheet 6 and preceding thin plate sheet 9, push into and prune from their both sides, thereby the fore-end of back thin plate sheet 6 and the rear end part of preceding thin plate sheet 9 are linked together.At this moment, the detected and measurement of the bending (state) of the rear end part of bending of the fore-end of back thin plate sheet 6 (state) and preceding thin plate sheet 9.Based on measurement result, calculate the bias δ of the center of link position place broad ways
fAnd δ
p, and calculate the 4th and the 5th vertical roller to 25 and 26 amounts of exercise that are used to regulate, thus make bias δ
fAnd δ
pReduce.The rear end part of the fore-end of back thin plate sheet 6 and preceding thin plate sheet 9 is mobile corresponding amount on horizontal rightabout.Therefore, at the link position place, can be minimum in the lateral run-out of preceding and back thin plate sheet 9 and 6.
When the rear end part of back fore-end of thin plate sheet 6 and preceding thin plate sheet 9 moved (bending) on horizontal rightabout, preferably, this moved (bending) amount in the scope of the strain of thin plate sheet.If surpass the scope of this strain, the residual amount of permanent deformation will appear on width, the first and the 5th vertical roller to 25,26 and link position between width position concern and will change constantly.Therefore, be difficult to guarantee desirable width position at the link position place.
As mentioned above, the lateral run-out during the connection is reduced to minimum, exists crooked in the rear end part of the lateral run-out during this connects owing to the fore-end of back thin plate sheet 6 or preceding thin plate sheet 9.Therefore, can be by guided plate to 28 bending with sizings, therefore can carry out finish rolling, reduce to comprise the bending on the whole length of link position simultaneously.Thin plate sheet 11 at the outlet side of finishing mill 4 by also being gratifying, because there be not crooked the existence.Also obtain such effect: the outward appearance of rolling of coiling big step can not occur at connecting portion.
In addition, when connecting portion passed through finishing mill 4, the transverse center position of the fore-end of the rear end part of preceding thin plate sheet 9 and back thin plate sheet 6 was almost identical with the center of whole length part (total body portion).This realizes the advantage that calendering is stable.
In addition, if can reduce departing from of center, just no longer there is big step in connecting portion.Therefore, when the entrance side of each milling train of finishing mill 4 was provided with side and leads device, this set method became easier.
In comprising the above-mentioned cross-level apparatus and method of overlap joint, the cut state of the fore-end of the rear end part of thin plate sheet or back thin plate sheet is necessary before reproducing with cutter (termination trimmer) before connection.In apparatus and method of the present invention, move this device so that the bending when reducing to connect is the very work of difficulty.Because the front end surface of back thin plate sheet or the rear end surface (it comprises the connection of overlapping region) of preceding thin plate sheet are not directly used in method of attachment, thereby can regulate by enough physical devices, and as effective means.And,, therefore, in some cases, need before connection, as above not cut with cutter (termination trimmer) because method of attachment is to finish connection in the pruning process of overlap condition.Because no matter therefore whether overlap joint, do not use cutter (termination trimmer) to cut, and can both reduce aforementioned bending.
