Abstract

PURPOSE:To enable the high-reliable detection of excess and deficient turn-tightening by means of a simple and inexpensive device, by a method wherein a turn-tightening part is irradiated with a light, and the number of light-receiving ranges, which are more than a set strength, is detected through the image-formation of a reflection light on an image sensor. CONSTITUTION:A turn-tightening part of a bin 1 with a cap, which forms the subject, is irradiated with a light from a light source 4, and a reflection light is image-formed on an image sensor 4, and a reflection light is image-formed on an image sensor 6 through a lens 5. If turn-tightening of a cap 3 is in a better condition, the reflection light is image-formed on one point as shown in a light ray 7. If the cap has hanging-down parts 15, 16 due to a poor turn-tightening, the reflection light shows 2 image-formation points or more as shown in light rays 8 and 9. With the bin 1 forwarded and rotated by means of a drive device, a pulse signal from an image sensor 6 is inputted to a decision circuit for good or bad turn-tightening condition, and the number of light-receiving ranges, which are more than a set strength, is found to decide the good or bad turn-tightening condition. This permits the high-reliable detection of excess and deficient turn-tightening by means of a simple and inexpensive device.
