System for detecting small holes in moving articles |
摘要 |
A small hole detection system which detects small holes in fast moving sheets of material. An array of LEDs is pulsed from an emitter which is aligned with an array of photocells positioned to detect light emitting from the emitter. The receiver sends a signal to a processing unit when light is detected. The small hole detection system may include an auto-shuttering mechanism which automatically adjusts the system according to the width of the material being scanned.
