Device for sorting different materials with the aid of a conveyor belt and an electromagnetic actuator

摘要

A device for sorting different materials comprises a conveyor belt ( 30 ), at least one sensor ( 37 ) that is allocated to the conveyor belt ( 30 ) and detects pieces of material according to the location thereof on the conveyor belt ( 30 ), and at least one actuator ( 24 ) which separates pieces of material in accordance with signals of the sensor(s) ( 37 ). The sorting device has an electromagnetic actuator ( 24 ) which includes an ejecting part ( 15 ) that is rotatable about a shaft ( 7 ) and is connected to at least one coil ( 10 ). The coil ( 10 ) is located in the air gap between two pairs, oppositely poled permanent magnets ( 8, 9, 22 ) and can be rotated from a zero position between the first oppositely magnetized pair ( 8 ) into a second position between the second oppositely magnetized pair ( 9 ). A rotational movement of the coil ( 10 ) causes the ejecting part ( 15 ) to separate the respective pieces of material.
