GRANULE SELECTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To perform cleaning of transparent bodies easily and surely by providing a constitution wherein a means for removing a foreign or black granule can be freely shifted from a position intruded between the transparent bodies to a position retreated from the position and vice versa. SOLUTION: An ejector means 9 as a means for removing a grain judged to be unacceptable or a foreign matter from a conveyor passage 6 has a blowing part 9A having an air blowing part and a solenoid valve 9B for switching air from an air feed apparatus to the air blowing part 9B. The unacceptable grain and foreign matter blown by the ejector means 9 are contained in a foreign matter container part 11 through a discharge opening 10. The ejector means 9 is supported approximately in an inverted U-shape in front view by connecting upper ends that are extended from both left and right sides thereof and further extended upward with each other by an operation lever 21 in such a manner as to be capable of being freely moved from a removal-enabled position for intruding the blowing part 9A between transparent plates A, B to a retreat position for retreating the same from between the transparent plates A, B and vice versa.
