Abstract

Provided is a sorting machine capable of more easily and efficiently sorting specific parts having a specific shape from raw materials containing various substances having different shapes, and a method for treating electronic and electric device component scraps using the sorting machine. The sorting machine includes a conveying device 1 having a conveying surface 13 which conveys raw materials containing substances having different shapes from a raw material inlet 11 to a receiving port 12; and a gate device 2 provided with a cylindrical roll portion 21 having a rotating function arranged at a certain distance d on the conveying surface to allow at least a part of the raw materials 100 to pass through to the receiving port 12.

First claim

1 . A sorting machine comprising:
a conveying device having a conveying surface which conveys raw materials containing substances having different shapes from a raw material inlet to a receiving port; and a gate device provided with a cylindrical roll portion having a rotating function, arranged with a certain space on the conveying surface to allow at least a part of the raw materials to pass through to the receiving port.

2 . The sorting machine according to claim 1 , wherein guides are provided at both ends of the conveying surface, and one of the guides comprises a notch which conveys the raw materials captured by the roll portion outside the conveying surface.

3 . The sorting machine according to claim 1 , wherein the conveying surface is inclined at 30 to 75 degrees with respect to a horizontal plane.

4 . The sorting machine according to claim 1 , wherein the roll portion has a central axis inclined to a conveying direction of the conveying surface.

5 . The sorting machine according to claim 1 , wherein a surface of the roll portion is formed of an elastic member.

6 . A method for processing electronic and electric device component scraps comprising sorting the electronic and electric device component scraps using a sorting machine according to claim 1 .

7 . The method for processing electronic and electric device component scraps according to claim 6 , wherein the electronic and electric device component scraps comprise component scraps including substrates, capacitors, and metal scraps that are sorted to a repulsive side by eddy current sorting.
