Abstract
PURPOSE: To make possible automatic detection and to increase the holding capacity by detecting the conditions of the reflected light in the vessel from a reflection member mounted on the inner surface thereof as the vessel is being static condition with respect to a photoelectric switch.
CONSTITUTION: A vessel having a reflecting member 6 such as mirror on the inner bottom is conveyed with a conveyor on a frame facing upward and detection is made to determine the existence of leftovers in the vessel when it reaches the frame 8. First, light is projected into the vessel with respective reflecting photoelectric switchs on through a cable 13 or the like. The light 16 reflected turns back to the photoelectric switches if there is no leftover in the vessel 5. On the other hand, if there is some leftovers therein, no light reflected returns to the switch. Or if there is some leftovers therein spreading thin over the reflection member 6, the light is returns to the switch but reduced in the intensity.
