IPC: G01N29/04
Filed: 1985-07-19
Abstract: PURPOSE:To enable efficient flaw detection, by setting a skew angle according to the specified equation depending on preset target feed pitch and specimen diameter, and correcting and controlling the skew angle in such a way that a transporting speed becomes the target-transporting speed defined by the preset target feed pitch and target peripheral speed. CONSTITUTION:A controller 7 performs arithmetic operation of a skew angle by the specified formula on the basis of an outside diameter numerical data of the specimen from a computer 11 and drives a skew angle adjusting motor 13 in such a way that it assumes the skew angle. next, the number of revolutions of a motor 8 is so adjusted that a peripheral speed of the specimen transported by a skew roller 1 set to the skew angle becomes the specified peripheral speed. Then, the transporting speed is calculated by a speed calculator 10 on a detecting signal from a photoelectric tube 14 and data of speed detecting encoder 9 of the motor 8 and the result is introduced into a controller 7 as an input. On the other hand, as the controller 7 drives again a motor 13 by obtaining a ratio of target-transporting speed and actually measured one, readjustment of the skew angle is unnecessitated and highly efficient flaw detection becomes available.
