[ In addition, the calibration unit 30 includes a second driving unit 34 and a third driving unit 36. The second driving portion 34 moves the pressing portion 32 to the slab 2 side so that the pressing portion 32 pushes the slab 2. [ The third driving part 36 is connected to the end of the second driving part 34 and moves the pressing part 32 upward so that the pressing part 32 can protrude and retract toward the conveying path side of the slab 2. At this time, if the pressing portion 32 and the supporting portion 22 are in close contact with the both ends of the slab 2, the control unit 6 stops driving the second driving unit 34. [ The third driving unit 36 is connected to the second driving unit 34 provided on the back surface of the pressing unit 32, respectively. The second driving unit 34 and the third driving unit 36 may be plurally installed to support the pressing unit 32.

Referring to Figs. 7 to 11, the calibration section 30 is installed below the conveying roller 12 and is movable along the conveying path of the slab 2. Fig. In other words, the calibration unit 30 further includes a fourth driving unit 38 connected to the lower end of the third driving unit 36 so that the pressing unit 32 can be moved back and forth along the conveying path of the slab 2. Thus, the calibration unit 30 is moved forward (refer to FIG. 8) along the conveying path of the slab 2 by the fourth driving unit 38, is moved upward by the third driving unit 36, Is moved forward (refer to FIG. 10) by the driving section 34, so that the pressing section 32 of the calibrating section 30 can easily push the slab 2. [ Since the calibration unit 30 is vertically moved by the second driving unit 34, the third driving unit 36 and the fourth driving unit 38, the position of the slab 2 can be easily calibrated , The shape of the slab 2 can be easily measured.

7, the second driving unit 34 is shown as being movable back and forth in the form of a cylinder, and the third driving unit 36 is shown as being vertically movable in the form of a cylinder. However, It is possible. Further, although the fourth drive unit 38 is shown as being movable back and forth with a rack and pinion structure, it can be designed and modified in various forms.

The pressure sensor portion 40 is provided in the pressure portion 32 and the pressure sensor portion 40 measures the shape of the slab 2 through the pressure of the slab 2 to be contacted. 12, the pressure sensor unit 40 can measure the width W and the thickness t of the slab 2 through the pressure of the slab 2 contacting one side.

 The length measuring sensor unit 50 is provided on the bridge 30 and the support 20 and the length measurement sensor 50 is mounted on the bridge 30 when the bridge 30 and the support 20 are closely attached to both ends of the slab 2 The controller 6 measures the distance between the bridge 30 and the support 20 and transmits the measured distance to the controller 6. The controller 6 calculates the distance between the bridge 30 and the support 20, Calculate the length. In this way, the user confirms whether the length of the slab 2 calculated through the control unit 6 is the same as the length information of the slab 2 input to the input unit 4, and rechecks the length of the slab 2 , But the length of the slab 2 can be accurately measured. Referring to FIG. 11, the length measuring sensor unit 50 is shown as an optical sensor, but it can be changed in various forms.

Hereinafter, the operation of the slab position correcting apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

When the slab 2 enters the roller table 10, the conveying roller 12 stops driving by the control unit 6, and the control unit 6 outputs the length information of the slab 2 input to the input unit 4 One of a plurality of support rods 20 provided under the conveying roller 12 is caused to protrude between the conveying rollers 12 in accordance with the conveying direction. At this time, the support portion 22 closest to one end of the slabs among the plurality of support rods 20 is moved upward by the first drive portion 24 and protruded toward the conveying path side. Subsequently, the pressing portion 32 provided in the calibration portion 30 provided so as to face the support table 20 is moved forward (refer to FIG. 8) along the conveyance path by the fourth driving portion 38. The pressing portion 32 is moved upward by the third driving portion 36 and protrudes toward the conveying path side of the slab 2 and is moved forward (refer to FIG. 10) by the second driving portion 34, 2). That is, the pressing portion 32 pushes the other end of the slab 2 to bring the one end of the slab 2 into close contact with the supporting portion 22. At this time, when the pushing portion 32 and the support portion 22 are brought into close contact with the both ends of the slab 2, the second driving portion 34 stops driving by the control portion 6.
