Abstract

PURPOSE:To make the finishing speed at high speed without improving the equipment remarkably by controlling the rotary speed of a laying head with the speed increase and reduction and by deliverying the wire end part from the head at the delivery target position where the speed increase and reduction quantity is minimum. CONSTITUTION:The delivery target position 26, 27 of the wire 3 of a laying head 5 is set in advance concerning the peripheral direction. And when the wire end part is detected by wire detectors 20, 21 the operation is performed as to whether the speed increase and decrease quantity of the rotary speed of the laying head 5 becomes minimum in case of at which position for delivery target the front and rear end parts being delivered by using an computing element 23 based on the work conditions at that time. Based on the result thereof the wire 3 is delivered at the position where the speed increase and decrease quantity is minimum by controlling the prescribed driving motor by a controller 24. The finishing speed can thus be made faster without large equipment improvement of extending the distance of the rolling mill, etc.

The first wire rod detector 20 is located between the intermediate rolling mill row 18 and the finishing rolling mill row 2. The second wire rod detectors 21 are arranged 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、レイングヘッド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.

演算する。Reference numeral 23 denotes a computing unit, which determines at which discharge target position the laying head 5
It is calculated whether the amount of acceleration or deceleration of the rotational speed of the laying head 5 will be the least if the front and rear ends of the wire rod 3 are discharged.

吐出目標位置でレイングヘッド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, accelerates and decelerates the rotational speed of the laying head 5, and controls the laying head at the discharge target position where the amount of acceleration and deceleration is the smallest. The front and rear ends of the wire rod 3 are discharged from the head 5.

次に、レイングヘッド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

向後方側を指向していれば、搬送時に問題は生じない。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 move around the cooling nozzle hole or other places around the cooling conveyor 7. There is no risk of the coil 6 getting caught in the equipment, 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.

それ故、レイングヘッド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
又はそれ以上であっても何ら問題は無いことがわかる。Therefore, it can be seen that the discharge target position of the front end portion of the wire 3 of the laying head 5 does not necessarily have to be a single position as in the conventional case, and there is no problem even if it has two or more positions.

Actual rolling speed of wire rod 3, (ii) first wire rod detector 2
Equivalent distance from 0 to laying head 5, (iii)
From the three working conditions of the position of the discharge port 12 of the vibrator 11 of the laying head 5 in the circumferential direction, the laying head 5
The expected discharge position of the front end of the wire 3 is calculated.

る。After that, the calculator 23 compares the scheduled discharge position with the already set target discharge position 26.27, and determines which target discharge position 26.27 the front end of the wire 3 is removed from the laying head 5. A calculation is made to determine whether the amount of acceleration/deceleration of the rotational speed of the laying head 5 would be the smallest if discharged, and the target discharge position 26 or 27, which would require the least amount of acceleration/deceleration, is selected.

２７に修正する。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. Accordingly, the wire rod 3 of the laying head 5
The discharge position of the front end portion is set to the discharge target position 26. selected above.
Corrected to 27.

置の制御を行うことも可能である。In addition, the finish rolling speed of the wire rod 3 is low, and the above-mentioned (1)
If the correctable angle θ shown in the formula can be set to 180 degrees or more without any problems, the discharge position of the front end of the wire 3 of the laying head 5 can be controlled using the setter 22 with the discharge target position being set to a single position. is also possible.

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 calculator 23. If this calculation can be performed instantaneously, the wire detectors 20 and 21 can be used as a single wire detector. Good too.

等を充分にとる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;
This is the distance
This is because, in general, the angle is not so large, and 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 taken.

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の下流側や中間
圧延機列１８の中間位置に配設する場合もある。Note that if the wire rod rolling equipment is different from a general one, the first wire rod detector 20 may be arranged downstream of the finishing rolling mill row 2 or at an intermediate position of 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るように

The amount of acceleration/deceleration of the rotational speed of the laying head 5 is calculated to be the smallest, and the laying head 5 is operated to discharge the end portion of the wire 3 from the laying head 5 at the discharge target position 26.27 where the amount of acceleration/deceleration is the smallest. Since the rotational speed of the head 5 is accelerated/decelerated controlled, the angle at which the discharge position can be corrected in the circumferential direction by acceleration/deceleration control of the rotational speed of the laying head 5 may be 180 degrees or less. Extension of the distance
The finish rolling speed of the wire rod 3 can be increased without making significant equipment improvements such as introducing a laying head 5 with a small D2. The present invention has the above advantages and is of great practical benefit.

る線材端部の吐出位置制御方法。1. The wire rod 3 coming out of the finishing rolling mill 1 is formed into a coil shape by a rotationally driven wire rod laying head 5, and this coil 6 is conveyed by a conveyor 7, and the rotational speed of the laying head 5 is accelerated or decelerated. By doing so, in the case where the discharge position of the end of the wire rod 3 of the laying head 5 is set at a predetermined position in the circumferential direction, the wire rod 3 of the laying head 5 is
A plurality of end discharge target positions 26 and 27 are set in advance in the circumferential direction, and the ends of the wire 3 are detected by the detectors 20 and 21 located upstream of the laying head 5, and the work at the time of this detection is performed. Based on the conditions, which discharge target position 26, 27
Then, if the end portion of the wire rod 3 is discharged from the laying head 5, the amount of acceleration/deceleration of the rotational speed of the laying head 5 can be minimized is calculated, and the discharge target positions 26, 27 are determined where the amount of acceleration/deceleration is the least. A method for controlling the discharge position of a wire rod end in a wire rod laying head, characterized in that the rotational speed of the laying head 5 is accelerated or decelerated in order to discharge the wire rod 3 end from the wire rod laying head 5.
