Abstract

PURPOSE: To suspend feed of a pelletlike insulation material of a part into which a metallic foreign matter is contained without suspending a production line of an electric wire and cable, by a method wherein high frequency is applied to a pelletlike insulation material to be conveyed, a metallic foreign matter mixed into the material is detected by light or a sound emitted by the metallic foreign matter and the material around the detected place is removed during conveyance.
CONSTITUTION: When a pelletlike insulation material 2 which is sent by air with a conveying device 4 comes to a high-frequency irradiation chamber 7 and a metallic foreign matter is mixed into the material 2, light and a sound are emitted by a part of the metallic foreign matter and detected by a detector 8. A valve opening and closing control device 11 turns a directional control valve 10 into an open state by a detected signal after the lapse of time which has taken a moving speed of the material 2 and a distance of the material 2 to the directional control valve 10 into consideration, an inlet of a discharge path 9 is opened and a conveying path 32 is closed. Then the pelletlike insulation material 2 containing the metallic foreign matter is discharged outside and removed from the conveying path 3. Then after the lapse of an appropriate time (sufficient time to discharge the pelletlike insulation material 2 containing the metallic foreign matter outside), the directional control valve 10 is made into a closed state.
