Abstract
A sorting apparatus is provided for sorting selected magnetically attractable articles from non-selected magnetically attractable articles in a stream of articles. A sensor generates sensor signals representative of a property associated with a selected class of magnetically attractable articles. A separator device includes an array of magnets. A controller receives sensor signals from the sensor, identifies a location within the stream of articles of a selected magnetically attractable article, and selectively activates one or more magnets of the array of magnets and thereby magnetically attracts the selected magnetically attractable article from a first trajectory into a second trajectory while allowing non-selected magnetically attractable articles to continue along the first trajectory.
