Description
Folgesteuerung Die Erfindung bezieht sich auf eine Folgesteuerung für programmabhängig verlaufende Prozesse, insbesondere für Wäschebehandlungsmaschinen, bei der den einzelnen Programmabschnitten elektronische Schaltstufen zugeordnet sind, die einzeln für die verschiedenen Programmfolgen angewählt werden können.Sequence control The invention relates to a sequence control for program-dependent processes, especially for laundry treatment machines, in which electronic switching stages are assigned to the individual program sections that can be selected individually for the various program sequences.
Der Erfindung liegt die Aufgabe zugrunde, eine Folgesteuerung der vorgenannten Art zu schaffen, die nach einer Stromunterbrechung das Programm selbsttätig bei dem Programmabschnitt wieder aufnimmt, bei dem die Stromunterbrechung aufgetreten ist.The invention is based on the object of a sequential control of the the aforementioned type to create the program automatically after a power interruption resumes at the section of the program at which the power interruption occurred is.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß den einzelnen Schaltstufen Kondensatoren zugeordnet sind, die nach Abschluß des vorhergehenden Programmabschnittes die jeweilige Schaltstufe auslösen.According to the invention this object is achieved in that the individual Switching stages are assigned to capacitors, which after completion of the preceding Trigger the respective switching stage.
Um zu vermeiden, daß ein Programmabschnitt nicht zu Ende geführt wird, bleibt zweckmäßig die Ladung der Kondensatoren so lange erhalten, bis der jeweilige Programmabschnitt abgeschlossen ist, so daß bei Stromausfall der eben ablaufende Programmabschnitt beim Wiedereinsetzen des Stromes wiederholt wird.To avoid that a program section is not completed, the charge of the capacitors is expediently retained until the respective Program section has been completed, so that in the event of a power failure the Program section is repeated when the power is restored.
Die Kondensatoren sind jeweils in den Gitterkreis eines Thyristors geschaltet. Dabei ist der Kondensator bei gezündetem Thyristor an Spannung gelegt. Dem Kondensator ist ein Kurzschließer zugeordnet, der nach Ablauf des jeweiligen Programmabschnittes vorübergehend geschlossen wird, so daß ein ungewolltes Wiederholen dieses Programmabschnittes ausgeschlossen ist.The capacitors are each in the grid circuit of a thyristor switched. The capacitor is connected to voltage when the thyristor is triggered. A short-circuiter is assigned to the capacitor, which after the respective Program section is temporarily closed, so that an unintentional repetition this program section is excluded.
In der Zeichnung ist eine Schaltstufe für eine erfindungsgemäße Folgesteuerung dargestellt.In the drawing is a switching stage for a sequence control according to the invention shown.
Die einem Programmabschnitt zugeordnete Schaltstufe enthält als Schaltelement einen Thyristor 1, der in den Erregerstromkreis eines den jeweiligen Programmabschnitt auslösenden Relais 2 geschaltet ist. In dem Gitterkreis des Thyristors 1 ist als Speichermittel ein Kondensator 3 angeordnet, dem ein die Gitterleitung unterbrechender Kontakt 4 und ein Kurzschließer 5 parallel geschaltet sind. Ein weiterer von dem Relais 2 betätigter Kontakt 6 verbindet den Kondensator 3 mit der Anodenzuleitung des Thyristors 1.The switching stage assigned to a program section contains a switching element a thyristor 1, which is in the excitation circuit of the respective program section triggering relay 2 is switched. In the grid circuit of the thyristor 1 is as Storage means a capacitor 3 is arranged to which a grid line interrupting Contact 4 and a short circuiter 5 are connected in parallel. Another of that Relay 2 actuated contact 6 connects the capacitor 3 to the anode lead of the thyristor 1.
Vor Programmbeginn wird der Kondensator 3 durch Betätigung der Taste 7 aufgeladen. Nach Abschluß des vorhergehenden Programmabschnittes wird der Kontakt 4 selbsttätig geschlossen und der Thyristor 1 durch den Kondensator 3 gezündet. Gleichzeitig mit dem Zünden des Thyristors 1 zieht das Relais 2 an und löst den Programmabschnitt aus. Gleichzeitig wird der Kontakt 6 geschlossen, so daß der Kondensator 3 wieder aufgeladen wird. Nachdem der Programmabschnitt beendet ist, werden der Schalter 8 geöffnet und der Kutzschließer 5 geschlossen. Dadurch wird der Thyristor 1 gelöscht und der Kondensator 3 entladen. Gleichzeitig mit dem Betätigen des Schalters 5 und des Schalters 8 wird der Kontakt 4 der nächsten Schaltstufe geschlossen und deren Thyristor, vorausgesetzt, daß der zugeordnete Kondensator aufgeladen ist, gezündet. Wenn dieser Kondensator nicht aufgeladen ist, z. B. weil dieser Programmabschnitt nicht erwünscht ist, wird der Schalter 4 der übernächsten Schaltstufe geschlossen.Before the start of the program, the capacitor 3 is charged by pressing button 7. After completion of the previous program section, the contact 4 is automatically closed and the thyristor 1 is ignited by the capacitor 3. Simultaneously with the triggering of the thyristor 1, the relay 2 picks up and triggers the program section. At the same time the contact 6 is closed so that the capacitor 3 is charged again. After the program section has ended, the switch 8 is opened and the door closer 5 is closed. This extinguishes the thyristor 1 and discharges the capacitor 3. Simultaneously with the actuation of the switch 5 and the switch 8, the contact 4 of the next switching stage is closed and its thyristor is ignited, provided that the associated capacitor is charged. When this capacitor is not charged, e.g. B. because this program section is not desired, the switch 4 of the next but one switching stage is closed.
Wird der Strom während des Ablaufs eines Programmabschnittes unterbrochen, wird das Stromtor 1 bei wiedereinsetzendem Strom durch den Kondensator 3 erneut gezündet, so daß der gesamte Programmabschnitt wiederholt wird. Eine Verwechselung der Programmabschnitte ist nicht möglich, da die Kondensatoren der den vorhergegangenen Programmabschnitten zugeordneten Schaltstufen entladen sind.If the power is interrupted while a program section is running, the current gate 1 is again when the current through the capacitor 3 restarts ignited so that the entire program section is repeated. A mix-up of the program sections is not possible because the capacitors of the previous ones Switching stages assigned to program sections are unloaded.
