すものとする。 1 and 2a to 2c are block diagrams of a flaw detection apparatus according to an embodiment of the present invention, and FIG. 3 is a block diagram of a conventional flaw detection apparatus. In the figure, 1 is a test material, 2 is a transport direction of the test material 1, 3 is a test material front and rear end detector, 4 is a transport device,
Reference numeral 5 denotes a conveying length measuring device attached to the conveying device 4, and 6 denotes a conveying length measuring device 5 that transmits the detection signal of the leading and trailing edge detector 3 of the specimen.
7 is a probe contacting/separating material drive device that is operated by the output of the tracking processing device 6; 8 is a flaw detection probe; 10 is a contact material auxiliary mechanism; 11 is a trigger that is brought into contact with the conveying operation of the test material 1; 12 is a contact material auxiliary mechanism 10;
contraction springs, 13a, 13 that cause the to perform an extension action;
b is a pantograph that keeps the extension motion parallel, 14a
, 14b is a stopper that limits the movement of the contact/separation material position of the contact material auxiliary mechanism section 10; 15 is a pusher for returning the trigger 11 to the initial position; 16 is a limit switch for detecting that the trigger 11 has returned to the initial position; 17 is a limit switch; This is the main frame of the contact material auxiliary mechanism.
In each figure, the same reference numerals indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

means for detecting the positions of the leading and trailing ends of the transported specimen, and means for tracking the detected positions of the leading and trailing ends of the specimen to the flaw detection probe position; and a means for bringing the flaw detection probe into contact with and separating from the rear end of the material to be tested, and a flaw detection means for detecting defects existing in the material to be tested by ultrasonic flaw detection or the like using the bonded flaw detection probe. In the flaw detection apparatus, the flaw detection apparatus includes a trigger that is brought into contact with the tip of the means for bringing the flaw detection probe into contact with and separating the material by a conveying operation of the tip of the material to be inspected, and a contact that is mechanically extended by the trigger. A flaw detection device characterized by comprising a material auxiliary mechanism section.
