CHUTE FOR OPTICAL SORTING MACHINE

摘要

A chute for an optical sorter sorting machine allows objects to be sorted to drop under gravity from the lower end of the chute, thereby supplying the objects to an optical detection section. The chute is provided with: a first portion which includes a portion for receiving the objects to be sorted which are supplied from a supply section; and a second portion which continues from the first portion The first portion is composed of a single part and has: flat surfaces along which the objects to be sorted flow down; and connection surfaces. The flat surfaces located upstream are bent downward, and the connection surfaces located downstream are is bent upward to form a smooth undulation in the surface along which the objects to be sorted flow down.

1. A chute for an optical sorting machine, the chute: receiving a sorted article fed from a feeding part; allowing the received sorted article to flow down a surface; and after that, allowing the sorted article to undergo free fall from a lower end and to be fed to an optical detecting part, the chute comprising: a first part including a part for receiving the sorted article fed from the feeding part; and a second part succeeding the first part and allowing the sorted article to undergo free fall from the lower end, wherein
the first part is composed of one component, the first part has: a plurality of flat surfaces which the sorted article flows down; and a joint plane joining the plurality of flat surfaces at an obtuse angle in a direction in which the sorted article flows down, the joint plane is configured by bending the flat surface that positions on an upstream side downward and the flat surface that positions on a downstream side is configured by bending the joint plane upward, and thereby, a smooth undulation is formed on the surface which the sorted article flows down.
