Abstract
Die Erfindung betrifft eine Abwurfvorrichtung an Band- oder Rollenförderern für Gegenstände, insbesondere Bleche oder Blechzuschnitte, aus elektrisch leitendem, nicht-ferromagnetischem Material. An der Abwurfstelle unterhalb der Förder ebene sind Magnete (6) angeordnet, die in dem Fördergut (2) Wirbelströme erzeugen, die das Fördergut (2) von dem För derer (1) abheben und abbremsen. An dieser Stelle oberhalb der Förderebene ist ein quer zur Förderrichtung (3) bewegter Band- oder Rollenförderer (4) angeordnet.The invention relates to a discharge device on belt or roller conveyors for objects, in particular metal sheets or sheet metal blanks, made of electrically conductive, non-ferromagnetic material. Magnets (6) are arranged at the discharge point below the conveyor level, which generate eddy currents in the conveyed material (2) which lift the conveyed material (2) off the conveyor (1) and slow it down. A belt or roller conveyor (4) moving transversely to the conveying direction (3) is arranged at this point above the conveyor level.
Description
Die Erfindung betrifft eine Abwurfvorrichtung an Band- oder Rollenförderern für Gegenstände, insbesondere Bleche oder Blechzuschnitte, aus elektrisch leitendem, nicht-ferromagnetischem Material.The invention relates to a discharge device on belt or roller conveyors for objects, in particular sheets or sheet metal blanks, made of electrically conductive, non-ferromagnetic material.
Aus der DE-OS 22 51 592 ist eine gattungsgemäße Vorrichtung bekannt, mit der Gegenstände aus Nichteisenmetall, die auf einer Transportvorrichtung gefördert werden, mit induktiver Wirkung abgebremst, von der Transportvorrichtung abgehoben und quer ausgefördert werden. Diese Vorrichtung ist jedoch verhältnismäßig aufwendig und nur betriebsbereit, wenn Strom fließt.A device of this type is known from DE-OS 22 51 592, with which objects made of non-ferrous metal that are conveyed on a transport device are braked with an inductive effect, lifted off the transport device and conveyed out transversely. However, this device is relatively complex and only works when current is flowing.
Aus der DE-AS 23 46 042 ist ein Bandförderer zum hängenden Transport von ferromagnetischem Gut bekannt. Durch Abschalten der Magnete kann das Fördergut an vorbestimmten Stellen zum Stapeln abgeworfen werden. Der bekannte Bandförderer ist aber auf den Transport von Fördergut aus ferromagnetischem Material beschränkt.DE-AS 23 46 042 describes a belt conveyor for the hanging transport of ferromagnetic goods. By switching off the magnets, the goods can be dropped at predetermined locations for stacking. However, the known belt conveyor is limited to the transport of goods made of ferromagnetic material.
Der Erfindung liegt die Aufgabe zugrunde, auf einem Band- oder Rollenförderer bewegtes Fördergut aus elektrisch leitendem nicht- ferromagnetischem Material an vorbestimmten Stellen vom Band- oder Rollenförderer abzunehmen und seitlich abzulegen.The invention is based on the object of removing material made of electrically conductive non-ferromagnetic material from a belt or roller conveyor at predetermined locations and depositing it laterally.
Durch die im Patentanspruch gekennzeichnete Lösung wird die gestellte Aufgabe gelöst. Durch die von dem oder den unterhalb der Förderebene angeordneten Magneten werden Wirbelströme in dem Fördergut erzeugt, die ein Magnetfeld hervorrufen, das dem von den Magneten erzeugten entgegengerichtet ist. Durch die abstoßende Kraft der Magnetfelder wird das Fördergut von dem Band- oder Rollenförderer abgehoben, dabei abgebremst und in Richtung quer zur Förderrichtung durch einen oberhalb der Förderebene angeordneten Band- oder Rollenförderer an die gewünschte Abwurfstelle seitlich des Band- oder Rollenförderers bewegt.The solution identified in the patent claim solves the problem. The magnet(s) arranged below the conveyor level generate eddy currents in the material being conveyed, which cause a magnetic field that is opposite to that generated by the magnets. The repulsive force of the magnetic fields lifts the material being conveyed off the belt or roller conveyor, slows it down and moves it in a direction transverse to the conveying direction by a belt or roller conveyor arranged above the conveyor level to the desired discharge point to the side of the belt or roller conveyor.
Die in der Zeichnung schematisch dargestellten Ausführungsbeispiele dienen der Erläuterung der Erfindung.The embodiments shown schematically in the drawing serve to explain the invention.
Fig. 1 zeigt eine Ausführungsform mit Längs- und Querförderung durch Bandförderer, Fig. 1 shows an embodiment with longitudinal and transverse conveying by belt conveyors,
Fig. 2 ein Ausführungsbeispiel mit Längs- und Querförderung durch angetriebene Rollen. Fig. 2 an embodiment with longitudinal and transverse conveying by driven rollers.
Auf dem Bandförderer 1 werden Platten 2 in Pfeilrichtung 3 transportiert. An der Abwurfstelle für die Platten 2 ist oberhalb der Förderebene ein Quertransport-Bandförderer 4 angeordnet, an dem die Platten 4 hängend in Pfeilrichtung 5 seitlich vom Bandförderer 3 abtransportiert und an die Ablagestelle gefördert werden.Plates 2 are transported on the belt conveyor 1 in the direction of arrow 3. At the discharge point for the plates 2 , a cross-transport belt conveyor 4 is arranged above the conveyor level, on which the plates 4 are transported hanging in the direction of arrow 5 to the side of the belt conveyor 3 and conveyed to the deposit point.
Um die Platten 2 vom Bandförderer 1 abzuheben, ist unterhalb der Förderebene der Magnet 6 angeordnet, der in der darüber befindlichen Platte 2 Wirbelströme induziert, die ein zu dem des Magneten 6 entgegengerichtetes Magnetfeld hervorrufen. Aufgrund der abstoßenden Wirkung der beiden Magnetfelder wird die Platte 2 aus elektrisch leitendem nicht-ferromagnetischem Material vom Bandförderer 1 abgehoben und an den Untertrum des Bandförderers 4 angedrückt. In hängender Lage kann die Platte 2 dann von dem Bandförderer 4 seitlich weggefördert und, nachdem die Platte 2 aus dem Magnetfeld des Magneten 6 herausbewegt worden ist, abgeworfen werden.In order to lift the plates 2 from the belt conveyor 1 , the magnet 6 is arranged below the conveyor level, which induces eddy currents in the plate 2 located above it, which produce a magnetic field opposite to that of the magnet 6. Due to the repulsive effect of the two magnetic fields, the plate 2 made of electrically conductive non-ferromagnetic material is lifted from the belt conveyor 1 and pressed against the lower run of the belt conveyor 4. In a hanging position, the plate 2 can then be conveyed sideways away from the belt conveyor 4 and, after the plate 2 has been moved out of the magnetic field of the magnet 6 , thrown off.
In Fig. 2 werden die Bandförderer 1 und 4 der Fig. 1 durch Rollenförderer 7 und 8 ersetzt. Die Magnete 6 liegen jeweils zwischen den Rollen des Förderers 7.In Fig. 2, the belt conveyors 1 and 4 of Fig. 1 are replaced by roller conveyors 7 and 8. The magnets 6 are located between the rollers of the conveyor 7 .
