Title:
DETECTION METHOD OF QUANTITY OF DUMPED GARBAGE
Document Type and Number:
Japanese Patent JPH10220724
Kind Code:
A
Abstract:

To enable accurate detection of the quantity of dumped garbage even when the garbage diffusively drops side ways within a vertical part of a dirt supply chute or long-sized dirt hangs from a dirt supplying device by arranging a plurality of amount of dumped garbage sensors as spaced at a specified interval parallel with the direction of dumping the garbage at the dirt supply chute.

Amount of dumped garbage sensors 14, 15 and 16 are all of a photoelectric tube type and are installed in a pair on the light emitting side and on the photodetecting side respectively. The sensors detect light intercepted time while dropping garbage G passes between the two sensors and integrate the detection time to measure a correct amount (volume) of the garbage G passing. The amount of dumped garbage sensors 14, 15 and 16 set the direction of detection parallel with the direction of dumping the garbage and three sets 14, 15 and 16 thereof are installed horizontal to the direction of dumping the garbage G so as to obtain a proper resolving power with respect to the width of the dirt supply chute 12. This can prevent missed and duplicated detection of the dropping garbage G thereby achieving an accurate proportion between the amount of the actually dropping garbage G and an amount of dumped garbage signal.
