DEUTSCHESGERMAN
Die Erfindung betrifft eine Schaltungsanordnung, mit der es möglich ist, in Abhängigkeit von zwei Gruppen von Steuerimpulsen an zwei verschiedene Klemmen Ausgangsströme zu liefern. Zu diesem Zweck werden zwei hintereinandergeschaltete Flip-Flop-Stufen verwendet, von denen die erste getrennte Eingangsklemmen für die Steuerimpulse und die zweite getrennte Ausgangsklemmen für die Steuerströme enthält.The invention relates to a circuit arrangement with which it is possible, depending on two Groups of control pulses to deliver output currents to two different terminals. To this Two flip-flop stages connected in series are used, the first of which is separate Input terminals for the control pulses and the second separate output terminals for the control currents contains.
Mit einer soldhen Anordnung kann beispielsweise folgende Aufgabe gelöst werden: In einer Förderanlage soll eine Weiche durch das Fördergut selbst gesteuert werden. Während das Fördergut an einem Signalgeber, z. B. einer fotoelektrischen Einrichtung, vorbeigeführt wird, wird in dieser Einrichtung ein Impuls erzeugt, der eine Weiche, die den weiteren Förderweg des Fördergutes bestimmt, umlegen soll. Soll nun jedoch auf Grund eines beliebigen anderen Kriteriums das beispielsweise von der Art des betreffenden Fördergutes abhängig ist, die Weiche nicht umgelegt werden, so wird dieses Kriterium dazu benutzt, in einer Anordnung ebenfalls einen Impuls zu erzeugen, der gespeichert wird und die Wirkung des folgenden Umschaltimpulses aufhebt. Die Steueranordnung erhält also für jede Impulsart je einen besonderen Eingang und je einen besonderen Ausgang. Es können aber auch andere Aufgaben gelöst werden, bei denen durch zwei verschiedene Impulse zwei voneinander verschiedene Steuerungen durchgeführt werden sollen, die jedoch voneinander in der beschriebenen Form abhängig sind.The following task, for example, can be achieved with a similar arrangement: In a conveyor system a switch should be controlled by the conveyed goods themselves. While the conveyed goods at a Signal generator, e.g. B. a photoelectric device, is passed in this device Generates an impulse that is supposed to flip a switch that determines the further conveying path of the conveyed material. If, however, on the basis of any other criterion, for example, the type of the relevant Depends on the material being conveyed, the switch is not moved, this criterion is used to in an arrangement also to generate a pulse that is stored and the effect of the the following switchover pulse. The control arrangement thus receives a special one for each type of pulse Entrance and a special exit each. But other tasks can also be solved, in which two different controls are carried out by two different impulses which, however, are dependent on each other in the form described.
Zur Erläuterung der Erfindung und der ihr zugrunde liegenden Aufgabe dient die Zeichnung. Die das Kernstück der Schaltungsanordnungen bildenden beiden Flip-Flop-Kreise sind mit Sp1 und Sp2 bezeichnet. Der Kreis Sp1 besteht beispielsweise aus den Transistoren T1 und T2, welche gegeneinander über die Parallelschaltung von Widerstand R11 und Kondensator C11 bzw. Widerstand R12 und Kondensator C12 rückgekoppelt sind. Die Betriebsspannung wird von einer Spannungsquelle U1 über Vorwiderstände R13 und Ru zugeführt. U2 und U1 sind Vorspannungsquellen für die Transistoren T1 und T2. In ähnlicher Weise ist der Flip-Flop-Kreis Sp2 aufgebaut. Er besitzt zwei Transistoren Ts und Td mit den Rückkopplungswiderständen R21, R22 und den Kondensatoren C21 und C22. Auch hier ist die Betriebsspannung U1 über Widerstände R2S und RM angeschaltet. In analoger Weise wie beim Flip-Flop-Kreis Sp2 werden auch hier die Vorspannungen U2, U3 und U1 angelegt. Den Transistoren T3 und T4 sind jedoch hier noch Leistungstransistoren T5 und T6 nachgeschaltet, deren Betriebsspannung U2 ist und in deren Ausgangskreis Steuereinrichtungen, beispielsweise Relaissteuerwicklun-The drawing serves to explain the invention and the object on which it is based. The two flip-flop circuits, which form the core of the circuit arrangements, are designated Sp 1 and Sp 2 . The circuit Sp 1 consists, for example, of the transistors T 1 and T 2 , which are fed back to one another via the parallel connection of resistor R 11 and capacitor C 11 or resistor R 12 and capacitor C 12. The operating voltage is supplied from a voltage source U 1 via series resistors R 13 and R u . U 2 and U 1 are bias sources for the transistors T 1 and T 2 . The flip-flop circuit Sp 2 is constructed in a similar manner. It has two transistors T s and T d with feedback resistors R 21 , R 22 and capacitors C 21 and C 22 . Here, too, the operating voltage U 1 is switched on via resistors R 2S and R M. The bias voltages U 2 , U 3 and U 1 are also applied here in a manner analogous to that in the case of the flip-flop circuit Sp 2 . The transistors T 3 and T 4 are followed by power transistors T 5 and T 6 , the operating voltage of which is U 2 and control devices, for example relay control windings, in their output circuit.

gen M1 und M2, geschaltet sind. Die Klemmen, welchen die Impulse der beiden Eingangsimpulsarten zugeführt werden, sind mit E1 und E2 bezeichnet.gen M 1 and M 2 , are connected. The terminals to which the pulses of the two input pulse types are fed are labeled E 1 and E 2.
E1 ist über einen Kondensator C0 und einen Gleichrichter G1 mit der Basis des Transistors T1 verbunden, während E2 über den Kondensator C3 und den Gleichrichter G2 an der Basis des Transistors T2 liegt. E2 ist darüber hinaus über den Kondensator C1 und einen Gleichrichter G3 an die Basis des Transistors T4 geschaltet, während die Basis des Transistors T3 über einen Gleichrichter G4 und einen Kondensator C2 vom Ausgang des Transistors T2 versorgt wird. Die Kondensatoren C1 und C2 sind über einem Widerstand derart miteinander verbunden, daß die der Steuerspannung entfernte Seite von C1 und der der Steuerung nahen Seite von C2 liegt. R15, R16, R17 und R18 sind Vorwiderstände im Bereich des Flip-Flop-Kreises Sp1 und R25, R2e, R21, R2S und R29 Vorwiderstände im Bereich des Flip-Flop-Kreises Sp2. Die Spannungen U1 bis Ui sind derart bemessen, daß sie entsprechend ihrer Indexzahl ansteigen. E 1 is connected to the base of the transistor T 1 via a capacitor C 0 and a rectifier G 1 , while E 2 is connected to the base of the transistor T 2 via the capacitor C 3 and the rectifier G 2 . E 2 is also connected to the base of transistor T 4 via capacitor C 1 and a rectifier G 3 , while the base of transistor T 3 is supplied from the output of transistor T 2 via a rectifier G 4 and a capacitor C 2. The capacitors C 1 and C 2 are connected to one another via a resistor in such a way that the side of C 1 remote from the control voltage and the side of C 2 which is close to the control are located. R 15 , R 16 , R 17 and R 18 are series resistors in the area of the flip-flop circuit Sp 1 and R 25 , R 2e , R 21 , R 2S and R 29 are series resistors in the area of the flip-flop circuit Sp 2 . The voltages U 1 to U i are dimensioned in such a way that they increase according to their index number.
Die Schaltung arbeitet folgendermaßen: Der positive Impuls, der an die Klemme E1 gelangt, wird am Kondensator C0 differenziert und gelangt über den Gleichrichter G1 an die Basis des Transistors T1. Das Potential an dieser Basis wird somit größer als die Vorspannung U2, so daß der Transistor T1 gesperrt und der Transistor T2 leitend wird. Der Punkt A in der Verbindungsleitung zwischen beiden Kreisen und am Verbindungspunkt von R1 und C1 erhält ein Potential, das ungefähr U2 ist. Der Kondensator C1 sperrt somit die Verbindung zu Sp2 für positive Impulse mit einer Spannung, die kleiner als die Diffe-The circuit operates as follows: The positive pulse which is applied to the terminal E 1, is differentiated and the capacitor C 0 passes through the rectifier G 1 to the base of the transistor T. 1 The potential at this base is thus greater than the bias voltage U 2 , so that the transistor T 1 is blocked and the transistor T 2 is conductive. The point A in the connection line between the two circles and at the connection point of R 1 and C 1 receives a potential which is approximately U 2 . The capacitor C 1 blocks the connection to Sp 2 for positive pulses with a voltage that is smaller than the difference

renz U2 —U1 ist. Ein positiver Impuls an E2, welcher innerhalb dieses Spannungsbereiches liegt, kann nun nicht an den Kreis 5^2 gelangen, da C1 so negativ aufgeladen ist, daß der Gleichrichter G3 gesperrt bleibt. Dieser Impuls gelangt nun an die Basis des Transistors T2, wodurch dieser gesperrt wird und der Kreis Sp1 in seine Ausgangslage zurückfällt. Hierbei entsteht ein positiver Potentialsprung am Kollektor des Transistors T2, der am Kondensator C2 differenziert wird und an die Basis des Transistors T3 ge- ίο langt. Dieser Transistor wird gesperrt, wodurch gleichzeitig der Transistor T5 gesperrt wird. Der Kreis Sp1 kippt nunmehr um, und der Transistor T1 wird durchgeschaltet. Dadurch wird aber auch der Transistor T6 durchgeschaltet, und die Steuerwicklung M1 wird erregt, während die Wicklung M2 stromlos bleibt.renz U 2 - U 1 . A positive pulse at E 2 , which is within this voltage range, can now not reach the circuit 5 ^ 2 , since C 1 is so negatively charged that the rectifier G 3 remains blocked. This pulse now reaches the base of the transistor T 2 , whereby it is blocked and the circuit Sp 1 falls back into its starting position. This creates a positive potential jump at the collector of the transistor T 2 , which is differentiated at the capacitor C 2 and reaches the base of the transistor T 3 . This transistor is blocked, whereby the transistor T 5 is blocked at the same time. The circuit Sp 1 now tips over, and the transistor T 1 is turned on. As a result, however, the transistor T 6 is also switched through, and the control winding M 1 is excited, while the winding M 2 remains de-energized.
Trifft jedoch vor dem an E2 gelangenden Impuls kein Steuerimpuls an E1 ein, so bleibt der Transistor T2 gesperrt und T1 durchgeschaltet. Der Punkt A liegt auf einem Potential, das ungefähr der Spannung U1 entspricht. Ein positiver Impuls von E2 kann somit das Potential an A über das Potential U2 erhöhen, wodurch der Transistor T4 und dementsprechend der Transistor T6 gesperrt werden und der Kreis Sp2 umkippt. Nunmehr ist die Wicklung M2 erregt und M1 stromlos.If, however, no control pulse arrives at E 1 before the pulse arriving at E 2 , transistor T 2 remains blocked and T 1 is switched on . The point A is at a potential which corresponds approximately to the voltage U 1. A positive pulse from E 2 can thus increase the potential at A above the potential U 2 , whereby the transistor T 4 and, accordingly, the transistor T 6 are blocked and the circuit Sp 2 tips over. The winding M 2 is now energized and M 1 is de-energized.
