Title:
OPTICAL SORTER
Document Type and Number:
Japanese Patent JP2021112693
Kind Code:
A
Abstract:
To provide an optical sorter which can accurately detect a defective sorting object, foreign matter and the like, improve the sorting performance, secure a light amount necessary for detection of the sorting object even when the sorting object is changed to the one in a different size, and suppress the occurrence of sorting failure due to the shortage in the light amount.SOLUTION: An optical sorter comprises: a chute which is arranged in an inclined manner in order to make a sorting object flow down; optical detection means which detects the sorting object at a detection position; and ejector means which sorts and removes the sorting object on the basis of a detection result by the optical detection means. The chute is provided with an optical detection slit orthogonal to the flow-down direction of the sorting object. The slit width of the optical detection slit is adjustable. The optical detection means uses the position where the optical detection slit is provided as the detection position, and the imaging means images the sorting object that flows down on the chute.SELECTED DRAWING: Figure 5
