Abstract
Description
Überwachuiigseinrichtung für Fördergurte Die Erfindung betrifft eine Überwachungseinrichtung für Fördergurte mit in Gurtrichtung in Abständen aufeinanderfolgend eingelegten,etwa die gesamte Gurtbreite überdeckenden elektrisch leitfähigen Einlagen, die einen Stromkreis bilden, in dem ein Sender untergebracht ist, der auf einen außerhalb des bördergurtes angeordneten ortsfesten Empfänger einwirkt, wobei die Frequenz des durch die Einlagen gebildeten Stromkreises von der Senderfrequenz abweicht, nach Patent 1 274 499. Monitoring device for conveyor belts The invention relates to a Monitoring device for conveyor belts with successive intervals in the direction of the belt inserted electrically conductive inserts covering approximately the entire width of the belt, which form a circuit in which a transmitter is housed on a Fixed receiver arranged outside the conveyor belt acts, the The frequency of the circuit formed by the inserts differs from the transmitter frequency, according to patent 1,274,499.
Der Erfindung liegt die Aufgabe zugrunde, die Überwachungseinrichtung der genannten Art zu verbessern.The invention is based on the object of the monitoring device of the type mentioned to improve.
Die Lösung der gestellten Aufgabe besteht darin, daß in dem durch die Einlagen gebildeten Stromkreis ferner noch ein Empfänger -und ein Gleichrichter untergebracht sind und daß außerhalb des Fördergurtes mindestens ein weiterer Sender ortsfest angeordnet ist, der dem in dem Stromkreis untergebrachten Empfänger Energie zuführt.-zie Erfindung ermöglicht es, dem in dem Fördergurt befidlichen Stromkreis die notwendige Energie in Form elektromagnetischer Wellen zuzuführen, ohne daß eine Störung oder sonstige Beeinflußung des außerhalb des Fördergurtes angeordneten ortsfesten Empfängers erfolgt. Der außerhalb des Fördergurtes ortsfest angeordnete Sender arbeitet vorteilhafterweise mit Frequenzen im Kilohertz-Bereich. Der Sender kann hierbei als Induktionsschleife ausgebildet sein, die entlang dem Fördergurt angeordnet ist.The solution to the problem is that in the by the deposits formed a circuit furthermore a receiver and a rectifier are housed and that outside the conveyor belt at least one other transmitter Is fixedly arranged, the energy accommodated in the circuit receiver feeds. -zie Invention makes it possible to be in the conveyor belt To supply the power circuit with the necessary energy in the form of electromagnetic waves, without a disturbance or other influencing of the outside of the conveyor belt arranged stationary receiver takes place. The stationary outside of the conveyor belt arranged transmitter works advantageously with frequencies in the kilohertz range. The transmitter can be designed as an induction loop that runs along the Conveyor belt is arranged.
In der Zeichnung sind zwei Ausführungsbeispiele des Gegenstandes der Erfindung dargestellt. Es zeigen: Fig. 1 eine Überwachungseinrichtung, deren leitfähige Einlagen einen geschlossenen und Fig. 2 eine Überwachungseinrichtung, deren leitfähige Einlage einen offenen Stromkreis bilden.In the drawing are two embodiments of the subject matter of Invention shown. The figures show: FIG. 1 a monitoring device whose conductive Deposits a closed and FIG. 2 a monitoring device, whose conductive Insert to form an open circuit.
Bei beiden husführungsbeispielen befinden sich innerhalb des Fördergurtes F ein Empfänger E7, ein Gleichrichter G und ein Sender S2, während außerhalb des Fördergurtes F ein Sender S1 und ein Empfänger E2 ortsfest angeordnet sind. Im Ausführungsbeispiel gemäß Fig. 1 ist der Stromkreis Kg geschlossen und im Ausführungsbeispiel gemäß Fig. 2 ist der Stromkreis Ko offen.Both house guides are inside the conveyor belt F a receiver E7, a rectifier G and a transmitter S2, while outside the Conveyor belt F, a transmitter S1 and a receiver E2 are fixedly arranged. In the exemplary embodiment 1, the circuit Kg is closed and in the embodiment according to Fig. 2, the circuit Ko is open.
Der ortsfest angeordnete Sender S1 sendet elektromagnetische -Wellen ausj die von dem Empfänger Ei aufgenommen werden. Der Empfänger El leitet die aufgenommene Energie über den Gleichrichter G zu dem Sender S2, der den Empfänger E2 beeinflußt.The stationarily arranged transmitter S1 sends electromagnetic waves ausj which are ingested by the recipient egg. The recipient El forwards the recorded Energy via the rectifier G to the transmitter S2, which influences the receiver E2.
Ist der Stromkreis Kg unterbrochen, so empfängt der Empfänger E2 kein Signal. Das Ausbleiben des Signals kann in bekannter Weise benutzt werden zur Einschaltung einer Warneinrichtung oder zur Abschaltung des Fördergurtantriebs.If the circuit Kg is interrupted, the receiver E2 does not receive anything Signal. The absence of the signal can be used in a known manner for switching on a warning device or to switch off the conveyor belt drive.
Bei dem Ausführungsbeispiel gemäß Fig.2 fließt innerhalb des Fördergurtes F infolge des offenen Stromkreises Ko normalerweise kein Strom. Erst wenn durch eine Beschädigung des Fördergurtes F die Leitungen L1 und L2 kurzgeschlossen werden, kann ein Strom-fließen. Die von dem Sender Sl dem Empfänger El zugeführte Energie gelangt nun über den Gleichrichter G zu dem Sender 2, der den Empfänger E2 beeinflußt. In diesem Fall kann das von dem Empfänger E2 aufgenommene Signal zur Einschaltung einer Warneinrichtung oder zur Abschaltung des i'ördergurtantriebs verwendet werden.In the embodiment according to Figure 2 flows within the conveyor belt F normally no current due to the open circuit Ko. Only when through Damage to the conveyor belt F lines L1 and L2 are short-circuited, can a current flow. The energy supplied to the receiver El by the transmitter S1 now arrives via the rectifier G to the transmitter 2, which influences the receiver E2. In this case, the signal picked up by the receiver E2 can be switched on a warning device or to switch off the conveyor belt drive.
