Claims

[Claims for Utility Model Registration] A portal-shaped moving support having a moving part that can move along an installed rail and supporting parts hanging down from both ends of the moving part, and at the lower ends of both supports of the moving support, A pair of copying roller stands each provided with a downward force and capable of sliding in the vertical direction, and a pair of copying roller stands provided with a pair of copying roller stands that are biased downwardly and can freely slide in the vertical direction; It has a pair of roller shafts each supported by a roller stand, bent diagonally downward in the middle, and a copying roller attached to the tip, and is connected to the rail in a horizontal plane below the copying roller stand. In a welding line copying device that performs a copying operation by sandwiching a workpiece to be welded that is conveyed in orthogonal directions between the pair of copying rollers, the roller shaft is slid to an intermediate position where the stroke lengths of both roller shafts are equal. A sensor that detects the stroke end position, which is the limit position on both sides, and when the stroke end position is detected by this sensor,
A weld line copying device comprising: a motor that moves a movable support along a rail in a direction in which the stroke lengths of both roller shafts are equal, and stops the movable support when an intermediate position is detected by a sensor. .
