Optical sorting machine

摘要

Problem to be solved: to detect the defective article or the foreign substance of the selected object with high accuracy, to improve the sorting performance, and to secure the quantity of light necessary for the detection of the selected object even when the object to be selected is changed to a different size. Problem to be solved: to provide an optical sorting apparatus which does not cause a malfunction due to insufficient light quantity.A shot placed in a tilted manner to cause the object to be droppedAn optical detection means for detecting said object at a detection positionAn ejector means for selectively removing and removing the selected object based on the detection result by the optical detecting meansEquipped withThe chute is provided with an optical detection slit perpendicularly to the falling direction of the object to be selectedThe optical detection slitThe slit width is adjustable.The optical detection means comprisesThe position where the optical detection slit is provided is set as the detection position.The object of the present invention is characterized by imaging the selected object flowing down the chute by the imaging means.Diagram
