Title:
TOBACCO INSPECTION APPARATUS
Document Type and Number:
Japanese Patent JPS60156374
Kind Code:
A
Abstract:
The optoelectronic device for checking the number, and/or the regularity of the ends, of the cigarettes making up an orderly group of cigarettes to be packed, comprises a box-like cigarette-checking head (1) in which a number of feeler pins (2) is axially slidably mounted, the said feeler pins (2) being pressed against the cigarette ends, and controlling a number of intercepting screens (4) located between light sources (10), such as light emitting diodes, and photosensitive elements (11), such as phototransistors. Air under pressure is fed into the box-like cigarette-cnecking head (1), and is caused to first sweep the light sources (10) and the photosensitive elements (11). Thus, dust is prevented from settling down on the light sources (10) and on the photosensitive elements (11), and the air under pressure flowing out of the box-like cigarette-checking head (1) through the feeler pin-guiding bores (3, 8) will remove any dust from said bores and guarantee the slidability of the feeler pins (2).
