Abstract

PROBLEM TO BE SOLVED: To deliver steel to a straightening line at a posture capable of stably biting the steel even when the steel is bent by inputting the information on the bend of a bend detecting means by a control means, and individually controlling the speed of a delivery device so that the target moving position of each delivery device capable of biting the determined steel in a straightening machine is matched with the position of the delivery device detected by a position detecting means. SOLUTION: The degree of the bend of a steel 1 is detected by a bend detecting means 3 from an upper part of a cooling bed 2, a control device 8 operates an optimum delivery posture to a detected straightening machine based on this information on the bend, the position of the delivery device 4 to set the steel 1 to the operated posture is operated, and each target moving position of the delivery devices 4 corresponding thereto is determined and added to a drive device 6. The drive device 6 controls the speed of a motor 5 so that the position of the delivery device 4 detected by a position detector 7 is matched with the target moving position added from the control device 8, and moves each device 4 in the direction A, and loads the steel 1 on a carrying table to transfer the steel in the direction B at this position.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel dispensing apparatus for dispensing steel from a cooling floor of a section steel rolling facility to a straightening line.

[0002]

2. Description of the Related Art In a shaped steel plant, a steel material after finish rolling is cooled to a certain temperature, which is a cooling floor, and then straightened by a straightening machine to correct the bending. Is ensured. But,
The degree of bending varies depending on the product type and rolling conditions. In particular, in the case of equilateral angle iron and unequal angle iron, the shape may be greatly bent, and when dispensed to the straightening line as it is, the tip of the steel material is greatly displaced from the appropriate biting position of the straightening machine, and biting failure may occur. Had to wake up.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to correct a steel material in a posture such that the steel material can be stably engaged with a straightening machine in a straightening line even when the steel material is bent. An object of the present invention is to provide a steel material dispensing device for dispensing to a line.

SUMMARY OF THE INVENTION The present invention relates to a steel material dispensing apparatus for dispensing steel to a straightening line for straightening a bend from a cooling floor of a shaped steel rolling facility. A plurality of dispensing devices for cooperatively dispensing on a transfer table of a line, bend detecting means for detecting a bent state of a steel material in a cooling floor and outputting bending information, and position detecting means for individually detecting the position of the dispensing device When,
Control means for inputting the bending information of the bending detecting means, and determining a movement target position of each dispensing device that enables the steel material to bite into the straightening machine of the straightening line, and a movement target position determined by the control means. And a drive device for individually controlling the speed of the dispensing device so that the position of the dispensing device detected by the position detecting means coincides with the driving device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 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, a steel material 1 is rolled by a finishing mill (not shown), cut by a hot saw, and then cooled by a cooling floor 2. The cooled steel material 1 is conveyed to a straightening line by four dispensing devices 4 arranged in the longitudinal direction. That is, the dispensing device 4 lifts the steel material 1 in the cooling floor 2, and then moves in the direction of arrow A to discharge 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,
Each position moved in the direction of arrow A is detected by the position detector 7. The driving of the electric motor 5 is controlled by a driving device 6 provided separately. In this case, the position detection signal of the position detector 7 is fed back to the driving device 6.

On the other hand, the bending state of the steel material 1 in the cooling floor 2 is detected by a bending detecting means 3 comprising a CCD (Charge Coupled Device) camera and an image processing device. The control device 8 calculates the optimal payout posture for the straightening machine, which is the next process, based on the bend information of the bend detecting means 3 and determines each movement target position of the payout device 4 having the payout posture. It is configured to be added to the corresponding driving device 6.

The operation of the present embodiment configured as described above will be described below. After finish rolling, the steel material 1 is cut by a hot saw into a cooling floor take-in length, and cooled to a certain temperature of the cooling floor 2, but bending may occur depending on the type of steel material, rolling conditions, and the like. The degree of bending of the steel material 1 is detected from above the cooling floor 2 by the bending detecting means 3 composed of a CCD camera and an image processing device. The control device 8 calculates an optimum payout posture for the straightening machine based on the detected bending information. That is, the posture which can be stably stuck in the straightening machine in the state of being dispensed from the cooling floor 2 is calculated. Subsequently, the control device 8 calculates the position of the payout device 4 (the position shown by the dotted line in the drawing) for bringing the steel material 1 into the calculated posture, and calculates the corresponding movement target position of the payout device 4. Determined and added to drive 6. The driving device 6 controls the position of the dispensing device 4 detected by the position detector 7
Motor 5 so as to match the movement target position added from
Are moved in the direction of arrow A, respectively. Then, at this position, the steel material 1 is placed on the transport table that transports the steel material 1 in the direction of arrow B.

As a result, even when the steel material is bent, the steel material can be paid out to the straightening line in such a posture that it can be stably engaged with the straightening machine of the straightening line.

In the above-described embodiment, a description has been given of a case where four dispensing devices 4 are arranged in parallel. However, the present invention is not limited to this, and even if the number is three or less, or five or more. Can be similarly implemented.

[0010]

As is apparent from the above description, according to the present invention, even when the steel material is bent, the steel material is straightened in such a posture that it can be stably engaged in the straightening machine of the straightening line. A steel material dispensing device for dispensing to the line is obtained.
