Digitale wegabhängige Steuereinrichtung
EMI1.1
<Desc/Clms Page number 2>
abhängigenDarüber hinaus ist an die Einrichtung Ph das Zeitglied in Form einer monostabilen Kippschaltung MK angeschlossen. Sie wird vom Ausgangssignal der Einrichtung Ph gekippt und kehrt nach ihrer Eigenzeit in die Ruhelage zurück. Ihr Ausgangssignal besetzt den ersten Eingang eines Undgatters Ul.
Der zweite Eingang dieses Undgatters wird von den komplementären Wegimpulsen besetzt. Mit Hilfe des Nichtgatters N wird in den Wegimpulspausen jeweils Signal an diesen Eingang gegeben. Dementspre- chend erhält das Zählwerk Z für die Dauer der Eigenzeit des Zeitgliedes zusätzliche Impulse, deren An- zahl von der Geschwindigkeit des Bandes abhängig ist. Das Zählwerk wird also selbsttätig um soviele Schritte fortgeschaltet, als der Steuerbefehl für das Organ mit Ansprechzeit (in diesem Fall die Weiche) früher gegeben werden muss. Zur Zeitbegrenzung der Zählimpulse können monostabile Kippstufen K vorgesehen sein.
Die Wirkungsweise ist in dem Diagramm Fig. 3 veranschaulicht. Im Zeitpunkt t = 0 wird von der Einrichtung Ph der Bandanfang signalisiert. Die Tachometermaschine TG gibt dann die Wegimpulse gemäss Zeile a. In den Wegimpulspausen erhält das Zählwerk zusätzliche Impulse gemäss Zeile b, während der Eigenzeit tMK des Zeitgliedes, so dass sich eine Fortschaltung des Zählwerkes gemäss Zeile c ergibt. Im vorliegenden Fall ist die Ansprechzeit durch vier zusätzliche Impulse berücksichtigt worden. Bei hö herer Geschwindigkeit steigt mit der Zahl der Wegimpulse auch die Zahl der zusätzlichen Impulse.
In Fig. 2 ist angedeutet, dass ein Organ mit geringerer Ansprechzeit über ein Verzögerungsglied V gesteuert werden kann.
Der Aufbau der Gatter sowie des Zeitgliedes ist weitgehend freizügig, vorteilhaft wird man die bekannten Transistor-und Diodenschaltungen heranziehen.
PATENTANSPRÜCHE :
1. Steuereinrichtung mit impulsmässiger Abbildung des Weges von laufenden Werkstücken bzw. Vorrichtungen veränderbarer Geschwindigkeit für Maschinen bzw. Anlagen mit Organen konstanter, nicht vernachlässigbarer Ansprechzeit, die durch ein von den Wegimpulsen betätigtes Zählwerk gesteuert werden, gekennzeichnet durch ein Zeitglied (MK) mit einer Eigenzeit gleich der maximalen Ansprechzeit, das die Zählung zusätzlicher Impulse in den Wegimpulspausen freigibt, so dass der in der Ansprechzeit zurückgelegte Weg selbsttätig unabhängig von der Geschwindigkeit berücksichtigt wird.

In addition, the timing element in the form of a monostable multivibrator MK is connected to the device Ph. It is toggled by the output signal of the device Ph and returns to the rest position after its own time. Your output signal occupies the first input of an und gate Ul.
The second input of this undgate is occupied by the complementary path impulses. With the help of the non-gate N, a signal is sent to this input in the distance pulse pauses. Accordingly, the counter Z receives additional pulses for the duration of the proper time of the timing element, the number of which depends on the speed of the belt. The counter is automatically advanced by as many steps as the control command for the organ with response time (in this case the switch) has to be given earlier. Monostable multivibrators K can be provided to limit the time of the counting pulses.
The mode of operation is illustrated in the diagram in FIG. At time t = 0, the start of the tape is signaled by the device Ph. The tachometer machine TG then gives the distance pulses according to line a. In the distance pulse pauses, the counter receives additional pulses according to line b, during the proper time tMK of the timer, so that the counter is incremented according to line c. In the present case, the response time has been taken into account by four additional pulses. At higher speeds, the number of additional pulses increases with the number of travel pulses.
In FIG. 2 it is indicated that an organ with a lower response time can be controlled via a delay element V.
The structure of the gates and the timing element is largely liberal; the known transistor and diode circuits will advantageously be used.
PATENT CLAIMS:
1. Control device with pulse-like mapping of the path of moving workpieces or devices with variable speed for machines or systems with organs of constant, non-negligible response time, which are controlled by a counter operated by the path pulses, characterized by a timing element (MK) with a proper time equal to the maximum response time, which enables the counting of additional pulses in the distance pulse pauses so that the distance covered in the response time is automatically taken into account regardless of the speed.
