Title: Printed matter inspection device
Inventor: HASHI ICHIROU
IPC: G06T7/00
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To automatically inspect whether or not the defect of a lack and thinning exists in printing given to the article of a resin cap and the like by detecting a difference between a generated appropriate master image and image data of printed articles which are sequentially image-picked up by an image pickup system and using the detection result as information for judging the propriety of printing. SOLUTION: When inspection trigger sensors 9A and 9B are turned on, image signals from CCD cameras 1-4 being image pickup systems are fetched in. Positions with an appropriate master picture which is previously generated/ registered are corrected. A difference is found by a subtraction processing with the appropriate master image and the image is judged to be good when the image difference is within a setting permission value. When the image difference exceeds the setting permission value, the abnormality of a lack, thinning and blotting and the eccentricity of printing are judged to occur in the mark of cap printing. Thus, the defect judgment rate of the good product can be suppressed to minimum and inspection can be automated.

A bolt insertion hole is bored through the piece 3 at the sites corresponding to the bolt holes 2, 2,..., of the split mold 1, and both surfaces are ground. The piece 3 is then put between the split mold 1 and 1 and clamped by a bolt to obtain a specimen 4. The specimen 4 is heated, quenched and ground, and the hardness is measured. Water is sprayed on the tip face of the specimen 4 in quenching to form a quenched end face 5. In grinding, both side end faces 6 of the piece 3 exposed on the periphery of the specimen 4 are ground over its entire length to a specified thickness. In the measurement of hardness, the hardness of both side end faces 6 is measured at each point at a specified distance from the end face 5. The difference in measurement between this and JIS method is small and conforms practically to the variance in heat treatment.
