The first wire rod detector 20 detects the front and rear ends of the intermediate rolling mill row 18 and the finishing rolling mill row 2.
In between, a second wire rod detector 21 is disposed between the finishing rolling mill row 2 and the water cooling zone 4, respectively.
２２は吐出目標位置設定器で、レイングヘツド
５の線材３前後端部の吐出目標位置を予め周方向
に関して複数設定しておくものである。 Reference numeral 22 denotes a discharge target position setting device, which presets a plurality of discharge target positions of the front and rear ends of the wire 3 of the laying head 5 in the circumferential direction.

うにした方がレイングヘツド５の回転速度の加減
速量が最も少なくて済むかを演算する。 Reference numeral 23 denotes a calculation unit which determines the acceleration/deceleration of the rotational speed of the laying head 5 at which discharge target position the front and rear ends of the wire 3 should be discharged from the laying head 5 based on the working conditions at the time of detection by the wire detectors 20 and 21. Calculate which amount requires the least amount.

ヘツド５から線材３前後端部を吐出させる。 24 is a controller that controls the laying head drive motor 9 based on the calculation result of the calculating unit 23 to accelerate and decelerate the rotational speed of the laying head 5, and to control the rotational speed of the laying head 5 from the laying head 5 at the discharge target position where the amount of acceleration/deceleration is the smallest. The front and rear ends of the wire rod 3 are discharged.
次に、レイングヘツド５の線材３前後端部の吐
出位置の制御方法を説明するが、下記の説明にお
いては、簡略化するために、線材３前端部の吐出
位置の制御方法のみについて説明する。 Next, a method of controlling the discharge position of the front and rear ends of the wire 3 of the laying head 5 will be described. In the following explanation, for the sake of simplicity, only the method of controlling the discharge position of the front end of the wire 3 will be described.
尚、線材３後端部の吐出位置の制御も、線材３
前端部の吐出位置の制御と同様に行える。 The discharge position of the rear end of the wire 3 can also be controlled by the wire 3.
This can be done in the same way as controlling the discharge position at the front end.
ところで、前述した様に、冷却コンベア７によ

前端部の冷却コンベア７上の位置が第６図に示す
位置からずれていても、前端部が搬送方向後方側
を指向していれば、搬送時に問題は生じない。 By the way, as mentioned above, when the coil 6 is conveyed by the cooling conveyor 7, if the front end of the coil 6 is oriented toward the rear side in the conveyance direction, the coil 6 will not touch the cooling nozzle holes or other equipment around the cooling conveyor 7. There is no risk of it getting caught, and even if the position of the front end of the coil 6 on the cooling conveyor 7 deviates from the position shown in FIG. 6, as long as the front end is oriented toward the rear in the conveying direction, No problems occur during transportation.
従つて、レイングヘツド５の線材３前端部の周
方向に関して吐出すべき位置は単一のポイントで
はなく、上記位置は周方向に関してある範囲内に
あればよいことがわかる。 Therefore, it can be seen that the position at which the front end of the wire rod 3 of the laying head 5 should be discharged in the circumferential direction is not a single point, but the position may be within a certain range in the circumferential direction.
それ故、レイングヘツド５の線材３前端部の吐
出目標位置は、従来のように、単一である必然性
は無く、２位置又はそれ以上であつても何ら問題
は無いことがわかる。 Therefore, it can be seen that the target discharge position of the front end of the wire 3 of the laying head 5 does not necessarily have to be a single position as in the prior art, and there is no problem even if it has two or more positions.
そこで、本発明におけるレイングヘツド５の線

件から、レイングヘツド５の線材３前端部の予想
される吐出予定位置を演算する。 During the rolling operation, when the first wire rod detector 20 detects the front end of the wire rod 3, the arithmetic unit 23
From three working conditions: () the actual rolling speed of the wire 3, () the equivalent distance from the first wire detector 20 to the rolling head 5, and () the position of the discharge port 12 of the pipe 11 of the rolling head 5 in the circumferential direction. , the expected discharge position of the front end of the wire 3 of the laying head 5 is calculated.

なくて済む吐出目標位置２６，２７を選択する。 After that, the calculation unit 23 calculates the scheduled discharge position and
Comparing the discharge target positions 26 and 27 that have already been set, it is determined at which discharge target position 26 or 27 the front end of the wire rod 3 is discharged from the laying head 5, the amount of acceleration or deceleration of the rotational speed of the laying head 5 is determined. The discharge target positions 26 and 27 that require the least amount of acceleration/deceleration are selected by calculating whether the least amount is required.

する。 Then, after the second wire detector 21 detects the front end of the wire 3, the controller 24 controls the laying head drive motor 9 to accelerate and decelerate the rotational speed of the laying head 5. The discharge position of the front end of the wire 3 of the laying head 5 is corrected to the selected discharge target positions 26 and 27.
尚、線材３の仕上圧延速度が低速であつて、前

180度以上とできる場合には、設定器２２により、
吐出目標位置を単一として、レイングヘツド５の
線材３前端部の吐出位置制御を行うことも可能で
ある。 Note that when the finish rolling speed of wire rod 3 is low, the angle θ that can be corrected as shown in equation (1) above can be adjusted without any problem.
If it is possible to set it to 180 degrees or more, use the setting device 22 to
It is also possible to control the discharge position of the front end of the wire 3 of the laying head 5 by setting a single target discharge position.
第１図において、線材検出器２０，２１を２個
備えたのは、演算器２３の演算時間を稼ぐためで
あり、この演算を若し瞬時に行えるのであれば、
線材検出器を単一としてもよい。 In FIG. 1, the reason why two wire detectors 20 and 21 are provided is to increase the calculation time of the calculation unit 23. If this calculation can be performed instantaneously,
A single wire detector may be used.

ことができないからである。 Furthermore, in FIG. 1, the first wire rod detector 21 is located between the intermediate rolling mill row 18 and the finishing rolling mill row 2; The distance x′ is generally not very large,
This is because if the first wire rod detector 20 is provided after the finishing rolling mill row 2, sufficient calculation time for the calculator 23 cannot be secured.
尚、線材圧延設備が一般のものと異なるような
場合には、第１線材検出器２０を仕上圧延機列２

る場合もある。 In addition, if the wire rod rolling equipment is different from general equipment, the first wire rod detector 20 is installed in the finishing rolling mill row 2.
In some cases, the rolling mill may be disposed downstream of the intermediate rolling mill row 18 or at an intermediate position in the intermediate rolling mill row 18.
又、実施例では、２つの吐出目標位置を設定す

するようにしてもよい。 Further, in the embodiment, two target ejection positions are set, but three or more target ejection positions may be set.
