Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a steel material dispensing device that dispenses a steel material from a cooling floor of a section rolling mill to a straightening line.
[0002]
[Prior art and problems to be solved by the invention]
In the shape steel equipment, the steel material after finish rolling is cooled to a certain temperature which is a cooling bed, and then the bending is corrected by passing through a straightening machine, and the shape as a product is secured. However, the degree of bending varies depending on the product type and rolling conditions. In particular, equilateral angle steel and unequal angle steel may bend greatly from their shape, and if they are fed directly to the straightening line, the tip of the steel will be greatly displaced from the proper biting position of the straightening machine, causing biting failure. I sometimes woke up.
[0003]
The present invention has been made in order to solve the above-described problems. The purpose of the present invention is to pay the steel material to the straightening line in such a posture that even if the steel material is bent, it can be stably bitten by the straightening machine of the straightening line. It is to provide a steel material discharging device.
[0004]
[Means for Solving the Problems]
The present invention is a steel material dispensing apparatus for dispensing steel material to a straightening line that corrects bending from a cooling floor of a shape steel rolling facility.
A plurality of dispensing devices that are arranged in the longitudinal direction of the steel material and cooperate to dispense from the cooling floor onto the conveying table of the straightening line;
Bending detection means for detecting the bending state of the steel material in the cooling floor and outputting bending information;
Position detecting means for individually detecting the position of the dispensing device;
Control means for inputting the bending information of the bending detection means and determining the movement target position of each dispensing device that enables the steel material to be bitten into the straightening machine of the straightening line;
A drive device that individually controls the speed of the payout device so that the movement target position determined by the control means matches the position of the payout device detected by the position detection means;
It is characterized by having.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on preferred embodiments shown in the drawings.
FIG. 1 is a block diagram showing a configuration of an embodiment of a steel material dispensing apparatus according to the present invention. In the figure, each steel material 1 is rolled by a finishing mill (not shown), cut by a hot saw, and then cooled by a cooling bed 2. The cooled steel material 1 is conveyed to the correction line by four dispensing devices 4 arranged in the longitudinal direction. That is, the payout device 4 lifts the steel material 1 in the cooling floor 2 and then moves in the direction of the arrow A to pay the steel material 1 out of the cooling floor 2. When the steel material 1 is placed on the table, the roller table conveys the steel material 1 in the direction of arrow B. Each of the four payout devices 4 is driven by an electric motor 5, and a position moved in the direction of arrow A is detected by a position detector 7. The electric motor 5 is driven and controlled by a driving device 6 provided individually. In this case, the position detection signal of the position detector 7 is fed back to the driving device 6.
[0006]
On the other hand, the bending state of the steel material 1 in the cooling floor 2 is detected by a bending detection means 3 constituted by a CCD (Charge Coupled Device) camera and an image processing device. The control device 8 calculates the optimal payout posture for the correction machine, which is the next process, based on the bending information of the bend detection means 3, and determines each movement target position of the payout device 4 that becomes this payout posture. It is the structure added to the corresponding drive device 6. FIG.
[0007]
The operation of the present embodiment configured as described above will be described below.
After finishing rolling, the steel material 1 is cut into a cooling bed incorporation length by a hot saw and cooled to a certain temperature which is the cooling bed 2, but bending may occur depending on the steel material type, rolling conditions, and the like. The bending state of the steel material 1 is detected from the cooling floor 2 by a bending detection means 3 composed of a CCD camera and an image processing device. The control device 8 calculates an optimal payout posture for the straightening machine based on the detected bending information. That is, a posture that can be stably bitten by the straightening machine in a state of being paid out from the cooling floor 2 is calculated. Subsequently, the control device 8 calculates the position (the position indicated by the dotted line in the drawing) of the payout device 4 for making the steel material 1 in the calculated posture, and sets each movement target position of the payout device 4 corresponding thereto. Determine and add to drive 6. The driving device 6 controls the speed of the electric motor 5 so that the position of the dispensing device 4 detected by the position detector 7 coincides with the movement target position applied from the control device 8, and moves the motor 5 in the direction of arrow A, respectively. And in this position, it mounts on the conveyance table which transfers the steel material 1 to the arrow B direction.
[0008]
As a result, even when the steel material is bent, the steel material can be delivered to the correction line in such a posture that it can be stably bitten by the correction machine of the correction line.
[0009]
In the above embodiment, the four dispensing devices 4 are arranged in parallel. However, the present invention is not limited to this, and the number of the dispensing devices 4 is three or less, or five or more. Can be similarly implemented.
[0010]
【The invention's effect】
As is apparent from the above description, according to the present invention, even when the steel material is bent, the steel material is delivered to the straightening line in such a posture that it can be stably bitten by the straightening machine of the straightening line. A dispensing device is obtained.
