In the present invention, the coil loaded on the working beam conveyor for material supply in the coil supplied to produce the product in the equipment for continuous rolling line is centering adjustment in the centering adjusting device skid, but the centering adjustment is not secured correctly. When the supply coil progresses to the process, equipment failure occurs due to interference with surrounding structures and equipment when the coil falls and enters the tip part, and automatic measurement and correction of the supply coil centering defect is prevented to prevent the continuous line from stopping and deterioration of work efficiency. Relates to a device.

In more detail, in order to prevent the fall of the material and interference when entering the leading end due to the poor centering adjustment of the coil supplied to the working beam conveyor for supplying the material of the continuous line entrance equipment, the dispersion calculation of the supply coil is supplied. Although the measuring method by the coil movement, the supply coil loaded on the centering adjustment device is fixed, and the deviation of the center of the supply coil is automatically measured and corrected by the movement of the optical sensor.

In a generally known hot dip plating facility, as shown in FIG. 1, the strip 10, which is a cold rolled coil or a micro-annealed steel sheet subjected to cold rolling after pickling, is heat-treated in a furnace 50 of a continuous plating line. After securing a predetermined material by passing through the zinc bath (ZINC POT) 51, and then adjust the plating amount by the air knife 52 installed on the upper side of the zinc bath (51) and then installed on the top It is to manufacture a plated steel sheet in a manner to cool by the cooling device (53).

As shown in FIGS. 2 to 4 in the conventional hot-dip plating technique related to the technique, the diffusion coil of the working beam conveyor kit 30C is adjusted by the operation of the working beam conveyor 30 for supplying the material. Deviation measurement and operation of the centering adjustment device 61 when moved to the device 61 will be described as follows.

When the working beam conveyor 30 moves backward for the purpose of moving the supply coil, the value of the working beam conveyor measurement distance PLG is reset to zero.

Subsequently, when the walking beam conveyor 30 performs the ascending operation and the ascending is completed, the working beam conveyor 30 moves forward to advance the supply coil of the walking beam conveyor No. 4 skid 30C to the centering adjusting device 61. ) Also measure distance.

The walking beam conveyor 30 moves forward to move the supply coil, and the supply coil moving to the optical sensor 62 installed between the fourth skid 30C and the centering adjusting device 61 is detected and the optical sensor 62 is detected. When on (0N) and then the optical sensor 62 is turned off (OFF) by the movement of the coil, the centering deviation calculation is completed and the centering adjustment device 61 is moved forward and backward to wait for the deviation much. 30) When the advance is completed, the descending and backward to the initial position, the centering adjustment operation of the centering adjustment device 61 when the supply coil loaded on the centering adjustment device 61 moves to the initial position of the centering adjustment device 61 Is also completed.

5 is a flowchart illustrating the operation of the above operation.

As shown in Fig. 4, the deviation measuring method of the centering adjusting device 61 is provided with a moving distance measuring pellet 64 of the working beam conveyor 30, and the distance measuring pellet 64 is a walking beam conveyor ( It was chained to detect a travel distance of 4100mm.

In addition, the optical sensor 62 detects the diffusion coil between the skid No. 4 30C and the centering adjustment device, and calculates the measured value of the peg 64.

However, in this way, the distance measurement of the PIG during the supply beam of the working beam conveyor during continuous supply of material for the continuous line material supply in the galvanizing process, or the operator misdetects the optical sensor or detects the material of the optical sensor. If the supply coil proceeds to the next process when the centering adjustment work is not normally performed due to the failure, the material breaks and the equipment breaks due to interference with the equipment or structure when entering the tip part. As a result, the operator should inspect and check the supply coil centering adjustment status every time.If the check result indicates that the supply coils need to be centered, the working beam conveyor is reversed and raised manually to lift all the supply coils loaded on the working beam conveyor skid. Raise and center the centering deviation randomly There was a problem in that the centering correction work was performed by moving the centering adjustment device to the initial position of the proximity sensor after moving the ring adjustment device forward and backward and operating the walking beam conveyor to the lower and initial positions.

In order to solve the above problems, the present invention is moved to the next process in the state of the centering of the supply coil generated during the automatic operation of the working beam conveyor is poor, and the equipment failure and interference with the equipment and structure when the supply coil falls and enters the front end Work delays occur and the operator has to lift all coils of the working beam conveyor skid by manual operation during the centering correction operation of the centering correction coil.The centering adjustment is automatically measured when the supply coil is stopped. In order to solve the problem of the centering of the supply coil centering adjusting device in the working beam conveyor, it is possible to prevent the progress to the next process and to automatically measure and correct the centering deviation without lifting all the coils of the working beam conveyor and the skid. Automatic measurement of diffusion coil centering failure and The purpose is to provide a correction device.
