Abstract

PURPOSE:To achieve an automatic ejection of a cullet, by detecting light transmitted through a cullet and light scattered thereby separately with two cameras to discriminate the type of the cullet with a level judgement in combination with various detection levels. CONSTITUTION:A light beam from a light source 6 is inputted direct into a first camera 7 through a slit 5 provided at the center position of a slide base 3 while light scattered by scattered foreign matters 2b is inputted into a second camera 8. Then, a transmission signal and a scattered light signal respectively outputted from the cameras 7 and 8 are inputted into a discrimination control section 9 to judge the type of individual cullet 2 positioned on the slit 5 from a signal (detection) level. When the foreign matters 2a and 2b are identified, an ejection command signal is sent to an ejection mechanism 10 provided on a plurality of through windows 10a are selected and turned downward to eject the foreign matters 2a and 2b.
