Next, the operation will be described. A strip (1) obtained by welding the end of the preceding coil and the start of the following coil in the preceding step of the steel process line is fed by a pinch roll (6), and a radiation detector (4) at the welded portion (2). When it reaches the position, the radiation detector (4) detects radiation such as a heat ray of light emitted by the residual heat of the welded portion (2) and outputs a signal. This signal causes the pinch roll (6) to stop feeding the strip (1). However, the radiation detector (4)
Even after the signal is output, the strip (1) may move slightly due to inertia, and the welded portion (2) may stop after passing the position of the radiation detector (4). At this time, a preliminary signal is output in advance to reduce the speed of the pinch roll (6), or the bead trimming device is made movable in the direction of the arrow in the figure, and the radiation detector (4) is again welded ( The movement is stopped when the position 2) is reached. Then, the strip (1) is pressed by the clamp (3), and a trimmer bit is run on the welded portion (2) for trimming.

Then, using the cylinder (11), trimmer ridge (10)
To the right to move the weld line detectors (14a), (14b),
The position detector (12) detects each of the on-timing and off-timing positions that are detected when the (14c) passes through the position of the welded portion (2) of the strip (1), and only a predetermined distance from the position of the off-timing. Overrun and stop for a while.
Again, the cylinder (11) is used to move the trimmer carriage (10) to the left to detect the on-timing and off-timing positions in the same manner (see FIG. 2, forward-direction on-timing, off-timing positions, return path). On-timing and off-timing positions and welding line detector (14a),
(14b) and (14c) are the distances to the positions before movement, which are indicated by A, B, C, and D, respectively). Welding line detectors (14a), (14b),
Since (14c) has a hysteresis characteristic, it is moved back and forth to detect the position of the welded portion (2) to improve accuracy. As soon as the position of the off-timing of the return path is detected, the position of the welding part (2) and the welding line detectors (14a), (14b), (14) are immediately detected.
Average distance X between the position before movement of c) and X = (A + B + C
+ D) / 4 is calculated for each of the welding line detectors (14a), (14b), (14c) (see FIG. 2). This is because, when the strip (1) is fed, its direction is displaced and the direction of the welded portion (2) is not perpendicular to the reference feeding direction of the strip (1). Of the calculated average distance, moving the Torimakiyaritsuji (10) to the position of the left 250mm from the position of the welded parts determined by the average distance X a for welding line detectors (14a) (2).

Next, the rotation angle Y for rotating the trimmer carriage (10) is calculated. When the width of the strips (1) is narrow, weld line detectors (14a), averaged (14b) Distance X a, rotation angle using a X b Y = (X a -X b) (1400/400 ) Is calculated, and if the strip (1) is wide, the weld line detector (14
The rotation angle Y = ( Xc- Xb ) (1/2) (1400/400) is calculated using the average distances Xb and Xc for b) and (14c) (third part).
See figure). When the trimmer carriage (10) is rotated by the cylinder (21) by this rotation angle Y, the strip (1) is pressed by the clamp (13) and the trimmer bite (17) is run, and then the welded portion (2) is reached. Trimming can be done along the way.

As described above, according to the present invention, a plurality of welding line detectors are attached to the trimmer carriage along with the trimmer bite, and the position of the welded portion stopped between the position of the welding line detector and the position of the trimmer bite is detected. The trimmer carriage is moved back and forth in order to be detected by the detector and the position detector attached to the trimmer carriage, and the average distance between the detected position of the welded part and the position before the movement of the weld line detector is calculated for each weld line detector. However, since the trimmer carriage is moved and / or rotated based on each average distance, the position of the welded portion can be accurately detected, and the trimmer bytes can be fed to the strip feeding direction or deviated from the reference feeding direction. Has the effect of being able to run along the welded part.
