Abstract
The invention is concerned with a method for identifying different, elongated metallic objects according to position and/or shape and/or type. In this method, by means of a conveyor, an object lying singly in a predetermined or a random position on conveyor is guided in terms of its conveyor direction evenly and at a constant speed over at least one inductive scanner, the induction voltage which varies temporally while object is passed over inductive scanner, is measured. The measurement signal detected in this manner over time is stored as an identification signal in an electronic data processor so as to produce an identification signal collection, and the signals generated by objects during operating passes are compared by the electronic data processor with identification signals stored in a data memory, and then evaluated, whereupon an electrical output signal which can be assigned to the respectively identified object position and/or shape and/or type and which can be used to control a storing apparatus is generated.
