Abstract

The present invention relates to a color sorting apparatus which efficiently sorts products or articles in a leaf state (hereinafter, referred to as ''leaf products'') such as green tea, black tea, chrysanthemum, herbs and the like, each of which has a low specific gravity and drastically varies in size and color. The color sorting apparatus is configured such that a reflection chamber (5) is arranged in a frame (3) in the lengthwise direction to transmit and reflect light emitted by a light source, an annular reflection surface (10) is formed at the surface of the reflection chamber (5), light-emitting diode (LED) arrays (8, 9) are installed at the top and bottom of the reflection chamber (5), respectively, a transparent window (12) is arranged at the front surface of the reflection chamber (5) to enable a leaf product (2) to move along the transparent window (12), a slit (15) is formed at the rear surface of the reflection chamber (5) to enable images of the leaf product (2) to be captured by a CCD camera (16), and a leaf product (2a) determined to be a defective product is quickly removed by the high-pressure air jetted by an ejector (14) installed below the front surface of the frame (3).

Description

technical field [0001] The invention relates to a color filter for leaf-shaped objects, which can quickly and effectively filter green tea leaves, black tea leaves, chrysanthemums, herbal tea leaves and other leaf shapes with low specific gravity, light weight, and large changes in size and color. or leaf-shaped products (hereinafter referred to as "leaf-shaped objects") are classified and screened. Background technique [0002] In general, color screeners are designed to screen grains such as rice, barley, wheat, beans, etc. as pass and reject as they fall freely. To this end, the color filter first judges whether the grains are acceptable or defective based on the color (or tone) discrimination obtained by image capture, and then instantly sprays high-pressure air to the unqualified grains. Unqualified grain (including impurities) removal. [0003] Generally, since high specific gravity grains such as rice, barley, wheat, beans can fall down at a constant speed along the...
