Japanese Patent JP2021134070
Kind Code:
A
Abstract:
To provide a jig for parallelism confirmation that enables inclinations of a pair of rolls to be easily adjusted so that shaft centers of the rolls are parallel to each other, and a parallelism adjustment method.SOLUTION: A jig 100 for parallelism confirmation, which adjusts inclinations of rolls, comprises: a camera unit 1 having a camera part 11 for photographing and a target; and a mirror unit 2 having a mirror part 21 including a flat reflecting plane on which the target is mirrored. The camera unit is arranged on a first roll 3a so that a direction of photographing by the camera is perpendicular to a direction of a shaft center of the first roll, and the mirror unit is arranged on a second roll 3b so that the reflecting plane of the mirror part is parallel to a shaft enter of the second roll. The target is configured to be positioned on a center line pointing in a direction perpendicular to the direction of the shaft center of the first roll of a center line of a lens extending in a direction perpendicular to the direction of photographing through a center of the lens of the camera part, with the camera unit arranged on the first roll.SELECTED DRAWING: Figure 1
