PROBLEM TO BE SOLVED: To provide an inspected material position adjusting mechanism of the non-destructive inspection equipment of a long-length material which can prevent the deterioration of inspection accuracy by compensating for the descending of an end part caused by the cantilever of the inspected material.SOLUTION: Either or both of an inlet-side grip roller 6 which sends a long-length material 2 being an inspected material into non-destructive inspection equipment 1, and an outlet-side grip roller 7 which draws the long-length material out of the non-destructive inspection equipment are made to serves as level variable rollers, the occurrence of the cantilever of the inspected material is detected by using either of proximity sensors 8, 8which are arranged at an inlet side and an outlet side of the non-destructive inspection equipment one by one, and the level variable roller at a side at which the cantilever occurs according to the detection is upwardly displaced by a level displacement amount h within a range not smaller than (y-c) and not larger than (y+c) which is defined by the following y, c. y: a maximum descending amount [mm] at a sensor part in the non-destructive inspection equipment by the own weight of a cantilevered part. c: an allowable clearance amount [mm] between the non-destructive inspection equipment and the inspected material.SELECTED DRAWING: Figure 1 |
