Abstract

Die Erfindung betrifft ein Verfahren zur Identifizierung von unterschiedlichen, länglichen metallischen Gegenständen nach Lage und/oder Form und/oder Art, bei dem mittels einer Fördereinrichtung (1) ein vereinzelt in vorgegebener oder beliebiger Lage auf der Fördereinrichtung (1) liegender Gegenstand (7) hinsichtlich seiner Förderrichtung gleichförmig und mit konstanter Geschwindigkeit über mindestens eine induktive Abtastvorrichtung (2a) geführt wird, die während des Passierens des Gegenstandes (7) über die induktive Abtastvorrichtung (2a) zeitlich sich verändernde Induktionsspannung gemessen und das so über der Zeit ermittelte Meßsignal (S1) zur Herstellung einer Erkennungssignalsammlung (ES) als Erkennungssignal in einer elektronischen Datenverarbeitungseinrichtung (3) gespeichert wird und die in Arbeitsdurchläufen von Gegenständen (4, 5, 6, 7) erzeugten Signale (S1, S2) mittels der elektronischen Datenverarbeitungseinrichtung (3) mit in einem Datenspeicher (9) abgelegten Erkennungssignalen verglichen und ausgewertet werden, wodurch ein der jeweils identifizierten Gegenstandslage und/oder -form und/oder -art zuordenbares elektrisches Ausgangssignal (AS) erzeugt wird, das zur Ansteuerung einer Sortiervorrichtung verwendbar ist.

Figure 00000001
The invention relates to a method for identifying different, elongated metallic objects according to their position and / or shape and / or type, in which an object (7) lying individually on the conveyor (1) in a predetermined or arbitrary position by means of a conveyor device (1). With regard to its direction of conveyance, it is guided uniformly and at a constant speed via at least one inductive scanning device (2a), which measures the time-varying induction voltage during the passage of the object (7) via the inductive scanning device (2a) and the measurement signal (S1 ) for producing a detection signal collection (ES) is stored as a detection signal in an electronic data processing device (3) and the signals (S1, S2) generated in work runs of objects (4, 5, 6, 7) by means of the electronic data processing device (3) with in a data memory (9) Detected signals are compared and evaluated, whereby an electrical output signal (AS) which can be assigned to the respectively identified object position and / or shape and / or type is generated and which can be used to control a sorting device.
