Eddy current sorting apparatus and eddy current sorting method

摘要

The eddy current sorting device includes a magnetic rotating disk (1) in which a plurality of permanent magnets are arranged in the circumferential direction by alternately reversing the polarity, and a pallet (2) arranged at a distance from the magnetic rotating disk. A drive unit (14) whose rotating shaft is attached to the magnetic field rotating disk, a supply unit (3) for holding the object to be sorted and supplying a specified amount of the object to be sorted to the pallet, and two A recovery unit (4), a magnetic rotating disk (1), and a drive unit for recovering an object to be sorted supplied from the supply unit to the pallet when the state is changed from a closed state to an open state. (14), a control unit (30) for controlling the supply unit (3) and the discharge unit (4), a first step of supplying a predetermined amount of the object to be sorted to the pallet from the supply unit, and a first step After a certain time has elapsed after the completion of the process, the second process for bringing the discharge part from the closed state to the open state, and the third process for returning the discharge part to the closed state after the completion of the second process. And execute, when the third step is completed, it executes the first step to the third step again.
