Abstract
Description
Am Rolltor list eine einen Stößel 5 betätigende Magnetspule 6 angebracht Das Bauteil Stößel 5 mit der Spule 6 kann dabei an der stirnseitigen Abschlußleiste des Rolltors, auf welche der Gummischlauch aufgeschoben und gegebenenfalls durch Klebung zusätzlich gehaltert ist, befestigt sein. Der Stößel 5 führt bei Erregung der Spule 6 eine Axialbewegung aus und beaufschlagt dadurch den Gummischlauch, so daß eine Signalgabe erfolgt. A solenoid 6 actuating a plunger 5 is attached to the roller door The component plunger 5 with the coil 6 can be attached to the end strip of the roller door, onto which the rubber hose is pushed and, if necessary, through Bonding is additionally held, be attached. The plunger 5 leads when excited the coil 6 from an axial movement and thereby acts on the rubber hose, see above that a signal is given.
Wie aus F i g. 2 ersichtlich ist, ist der Gummischlauch 2 in einem Zweig einer an der Speisespannung Uliegenden Wheatstone-Brücke angeordnet und verkörpert den Brückenwiderstand R4. Die übrigen Zweigwiderstände sind mit R1, R2 und R3 bezeichnet. As shown in FIG. 2 as can be seen, the rubber hose 2 is in one Branch of a Wheatstone bridge connected to the supply voltage U is arranged and embodied the bridge resistance R4. The remaining branch resistances are labeled R1, R2 and R3.
An den Brückenausgang (usa) ist ein Operationsverstärker 7 angeschlossen, dessen Ausgang an je einen Eingang eines UND-Glieds 8, 9 geführt ist. Das UND-Glied 8 ist ausgangsseitig mit dem R-Eingang eines bistabilen Flip-Flops 10 verbunden, dessen Ausgang einmal an die Basis eines Transistors T und zum andern an den Eingang eines weiteren UND-Glieds 11 gelegt ist, dessen Ausgang an die Basis eines zweiten Transistors T2 angeschlossen ist. Die beiden emitterseitig an Masse liegenden Transistoren T, und T2 sind kollektorseitig jeweils mit einem Hilfsrelais Dl und D2 verbunden, deren Ruhekontakte d, und d2 in Reihe in der vom Massepunkt der Magnetspule 6 zu einen Pol 12 des Tastschalters 13 führenden Leitungsverbindung liegen. An operational amplifier 7 is connected to the bridge output (usa), the output of which is led to one input each of an AND element 8, 9. The AND element 8 is connected on the output side to the R input of a bistable flip-flop 10, its output once to the base of a transistor T and the other to the input a further AND gate 11 is placed, the output of which is connected to the base of a second Transistor T2 is connected. The two transistors connected to ground on the emitter side T, and T2 are each connected to an auxiliary relay Dl and D2 on the collector side, their normally closed contacts d, and d2 in series in the from the ground point of the solenoid 6 to a pole 12 of the push button switch 13 leading line connection lie.
Der S-Eingang des Flip-Flops 10 ist über einen Kondensator Cx und einem diesem nachgeschalteten ohmschen Widerstand R5 mit dem Pol 12 des Schalters 13 verbunden. An die Verbindung zwischen der aus dem Kondensator C und dem Widerstand R5 gebildeten Reihenschaltung sind der zweite Eingang des UND-Glieds 11, der zweite Eingang des UND-Glieds 8 sowie die verknüpften Eingänge des NICHT-Glieds 15 angeschlossen. Dem NICHT-Glied 15 ist das UND-Glied 9 nachgeschaltet, das ausgangsseitig über einen Kondensator C2 an den Setzeingang des Flip-Flops 10 geführt ist. The S input of the flip-flop 10 is through a capacitor Cx and a downstream ohmic resistor R5 to pole 12 of the switch 13 connected. At the connection between the capacitor C and the resistor R5 formed series circuit are the second input of the AND gate 11, the second Input of AND element 8 and the linked inputs of NOT element 15 are connected. The NOT element 15 is followed by the AND element 9, the output side via a Capacitor C2 is led to the set input of flip-flop 10.
Die Schaltungsanordnung arbeitet wie folgt: Zur Einleitung der Abwärtsbewegung des in seiner oberen Endlage befindlichen Rolltors 1 wird der Tastschalter 13 betätigt, das heißt, geschlossen. Damit liegt die Reihenschaltung aus R5 und C an Spannung, und das Flip-Flop 10 wird gesetzt. Demzufolge sperrt der Transistor Tn und das Hilfsrelais D1 fällt ab. Des weiteren steht am unteren Eingang des UND-Glieds 11 und damit an dessen Ausgang kein Signal an, so daß der Transistor T2 sich ebenfalls im Sperrzustand befindet und dementsprechend auch das Hilfsrelais D2 abfällt. The circuit arrangement works as follows: To initiate the downward movement of the roller shutter 1 located in its upper end position, the pushbutton switch 13 is actuated, that is, closed. This means that the series connection of R5 and C is connected to voltage, and the flip-flop 10 is set. As a result, the transistor Tn and the auxiliary relay are blocked D1 drops out. Furthermore, there is 11 and thus at the lower input of the AND element whose output has no signal, so that the transistor T2 is also in the blocking state and the auxiliary relay D2 drops out accordingly.
Über die beiden in Reihe liegenden Hilfskontakte d, und d2 der jetzt spannungslosen Hilfsrelais D1 und D2 und den Schalter 13 liegt die Magnetspule 6 an Spannung (Spannung Ul), so daß ein Stromfluß zustande kommt, die Magnetspule 6 erregt und somit der Stößel 5 in Pfeilrichtung bewegt wird und auf den Meßwertgeber 2 auftrifft. Dadurch wird der Gummischlauch mechanisch deformiert und gibt infolgedessen ein Signal ab, das an seinen beiden Enden E1 und E2 abgenommen wird und an der Wheatstone-Brücke als Ausgangssignal U, erscheint. Dieses Signal gelangt zum Eingang des Operationsverstärkers 7, dessen Ausgangssignal ein Zurücksetzen des Flip-Flops 10 bewirkt, da nunmehr an beiden Eingängen des UND-Glieds 8 Signale anstehen. Via the two auxiliary contacts d, and d2 in series of the now The solenoid 6 is connected to the de-energized auxiliary relays D1 and D2 and the switch 13 at voltage (voltage Ul), so that a current flow comes about, the solenoid 6 excited and thus the plunger 5 is moved in the direction of the arrow and onto the transducer 2 occurs. As a result, the rubber hose is mechanically deformed and consequently gives a signal that is picked up at both ends E1 and E2 and at the Wheatstone bridge as output signal U appears. This signal goes to the input of the operational amplifier 7, the output signal of which causes the flip-flop 10 to be reset, since now 8 signals are present at both inputs of the AND element.
Der Transistor T gelangt daher wieder in den leitenden Zustand, desgleichen der Transistor T2, da beide Eingänge des UND-Glieds 11 signalbeaufschlagt sind. Damit erhalten die beiden Hilfsrelais D1 und D2 wieder Spannung und sprechen an. Die Ruhekontakte dl und d2 der beiden Hilfsrelais öffnen, und die Magnetspule 6 wird spannungslos bzw. entregt.The transistor T therefore returns to the conductive state, likewise the transistor T2, since both inputs of the AND element 11 are acted upon by signals. The two auxiliary relays D1 and D2 receive voltage again and respond. The normally closed contacts dl and d2 of the two auxiliary relays open, and the solenoid 6 becomes dead or de-energized.
Über einen Schließkontakt d22 des Hilfsrelais D2 und einen Schließkontakt dll des Hilfsrelais D1 erhält das Motorschütz 14 Spannung, das Schütz zieht an und der Antriebsmotor 4 läuft an, so daß sich das Rolltor abwärts bewegt. Via a make contact d22 of the auxiliary relay D2 and a make contact dll of the auxiliary relay D1, the motor contactor 14 receives voltage, the contactor picks up and the drive motor 4 starts up so that the roller door moves downwards.
Nach Loslassen des Tastschalters 13 fällt das Hilfsrelais D2 wieder ab, da am oberen Eingang des UND-Glieds 11 O-Signal vorhanden ist und der Transistor T2 daher wieder in den Sperrzustand gelangt. Der Schließkontakt d22 des Hilfsrelais D2 geht in seine Öffnungslage und wird durch einen Kontakt 16 des Motorschützes 14 überbrückt, wodurch sich dieses selbst hält. Das Hilfsrelais D1 bleibt weiterhin angezogen. After releasing the pushbutton switch 13, the auxiliary relay D2 drops again from, since at the upper input of the AND gate 11 there is a 0 signal and the transistor T2 therefore returns to the blocking state. The normally open contact d22 of the auxiliary relay D2 goes into its open position and is triggered by a contact 16 of the motor contactor 14 bridged, whereby this holds itself. The auxiliary relay D1 remains dressed.
Wird während der Abwärtsbewegung des Rolltors 1 aufgrund eines in der Bewegungsbahn des Rolltors befindlichen Hindernisses 3 am Gummischlauch 2 ein Signal erzeugt, so wird wie im Falle des »Funktionsprüfungssignals« das Flip-Flop 10 gesetzt, und zwar über das UND-Glied 9 und den Kondensator C2, wobei der zweite (untere) Eingang des UND-Glieds 9 über das NICHT-Glied 15 ein Signal erhält. Durch das Setzen des Flip-Flops 10 wird der Transistor T, wieder gesperrt (der Transistor T2 befindet sich ohnehin noch im gesperrten Zustand). Das Hilfsrelais D1 fällt ab, sein Arbeitskontakt dll unterbricht den Haltestromkreis des Motorschützes 14, so daß dieses ebenfalls abfällt und den Motor 4 von seiner Speisespannung trennt. Die Abwärtsbewegung des Rolltors 1 ist damit gestoppt. Is during the downward movement of the roller door 1 due to an in the obstacle 3 located on the rubber hose 2 along the path of movement of the roller door Signal generated, as in the case of the "function test signal" is the flip-flop 10 set, via the AND gate 9 and the capacitor C2, the second The (lower) input of the AND element 9 receives a signal via the NOT element 15. By the setting of the flip-flop 10, the transistor T, is blocked again (the transistor T2 is still in the locked state anyway). The auxiliary relay D1 drops out, its normally open contact dll interrupts the holding circuit of the motor contactor 14, see above that this also drops and separates the motor 4 from its supply voltage. the The downward movement of the roller door 1 is thus stopped.
Nach entferntem Hindernis und erneuter Betätigung des Tastschalters 13 wiederholt sich der im vorstehenden beschriebene Testablauf, und der Motor 4 läuft erst wieder an, wenn ein Testsignal am Gummischlauch 2 ansteht und die Auswerteschaltung ordnungsgemäß arbeitet. After removing the obstacle and pressing the pushbutton switch again 13, the test sequence described above is repeated, and the motor 4 does not start again until a test signal is present on rubber hose 2 and the evaluation circuit working properly.
Ein Ingangsetzen des Rolltors ist somit immer erst nach einer Funktionsprüfung des Gummischlauchs und der Auswerteschaltung und nur dann möglich, wenn diese Funktionsprüfung positiv verlaufen ist. The roller shutter can only be started after a functional test of the rubber hose and the evaluation circuit and only possible if this functional test went positively.
Der Gummischlauch 2 kann durch in seine Wandung einvulkanisierte elektrische Leiter in Widerstandszonen unterteilt sein, die jeweils einen Zweig einer Meßbrücke bilden können. The rubber hose 2 can be vulcanized into its wall electrical conductors can be divided into resistance zones, each with a branch can form a measuring bridge.
Die Halterung der Magnetspule 6 mit dem Stößel 5 am Rolltor 1 erfolgt zweckmäßigerweise an der untersten Leiste 17, an der auch der Gummischlauch befestigt ist. The magnetic coil 6 is held with the plunger 5 on the roller door 1 expediently on the lowest bar 17, to which the rubber hose is also attached is.
