Programme switching device, more particularly for household machines, having a programme cam drum (1) and a timer cam drum (2), both of which have inner teeth (9 or 10) ; having a stepping mechanism comprising a rocker (22) which is driven by a driving motor by way of an eccentric (20) and in which first spring-loaded plungers (16, 17) are guided, which plungers cooperate with the inner teeth (10) of the timer cam drum (2) normally covering the inner teeth (9) of the programme cam drum (1) and, with corresponding control slots (32) in the inner teeth (10) - projecting through said control slots (32) - come into engagement with the inner teeth (9) of the programme cam drum (1), characterised in that arranged inside the programme cam drum (1) there is a time extension ring (3) which is likewise provided with inner teeth (11, 12) and at least one control slot (33) and with which there is associated at least one further spring-loaded plunger (19) which is guided in the rocker (22) and cooperates with the inner teeth (11) of the time extension ring (3) and with the inner teeth (9) of the programme cam drum (1) in a manner corresponding to that of the first plungers (16, 17) for the timer cam drum (2) and programme cam drum (1), in that the plunger-driven time extension ring (3) is provided further with a resetting spring (29) acting on a housing projection (31) and also with a reverse blocking lever (25) for the time extension ring (3) and in that this blocking lever (25) is effective in dependence on the presence or non- presence in its area of engagement of additional teeth (27) of the programme cam drum (1) associated with said lever, such that no resetting of the time extension ring (3) takes place when additional teeth (27) are present, yet resetting does take place when the additional teeth (27) of the programme cam drum (1) are not present and when the blocking lever (25) lifts out of these teeth (27) when programme cam drum (1) moves further.

Description

Die Erfindung bezieht sich auf eine Programmschalteinrichtung, insbesondere für Haushaltsmaschinen, mit einer Pro- . grammnockentrommel, einem Zeitgebernockenrad sowie einem Zeitdehnungsring von einem Antriebsmotor über ein Schrittschaltwerk, dessen Transportorgan in unterschiedliche Verzahnungen eingreift, angetrieben sind.The invention relates to a program switching device, in particular for household machines, with a pro-. gram cam drum, a timing cam wheel and a time expansion ring are driven by a drive motor via a step-by-step mechanism, the transport element of which engages in different toothings.

Bei einer bekannten Programmschalteinrichtung der obengenannten Art (DE-OS 2 040 464) wird der Zeitdehnungsring durch die Transportklinge solange bewegt, bis Anschlagnocken an der Programmtrommel anliegen und diese mitnehmen, bis die Verzahnung in der Programmtrommel wieder wirksam ist. Dies bedeutet, daß die Programmtrommel erst soviel Schritte durchzuführen hat, bis der Zeitdehnungsring mit einem weiteren Anschlag von der Programmtrommel mitgenommen wird. Der Erfindung liegt somit die Aufgabe zugrunde, eine Programmschalteinrichtung der obengenannten Art zu schaffen, mit der mit einfachen Mitteln und einfachem Aufbau eine Vervielfachung der vom Zeitgeber vorgegebenen Schrittzeiten auf praktisch allen Nockentrommelpositionen durchführbar ist. Dies wird bei einer Programmschalteinrichtung der obengenannten Art auf einfache Weise dadurch erreicht, daß der Zeitdehnungsring entgegen der Transportrichtung federelastisch mit gehäusefesten Teilen verbunden ist. Hierbei ist es vorteilhaft, um eine definierte Langzeit zu erhalten, wenn das Transportorgan in Steuerabhängigkeit von dem Zeitgebernockenrad und dem Zeitdehnungsring mit der Verzahnung der Programmnockentrommel in Eingriff bringbar ist. Der Zeitdehnungsring kann durch entsprechende Ausbildung der Federkraft und der Reibungsverhältnisse bis in die gewünschte Position gebracht werden. Besonders vorteilhaft ist jedoch, um auch größere Zeit-La 2 Syr/13.07.1983 intervalle entgegen der Federkraft zu überwinden, wenn eine Rückdrehsperre für den Zeitdehnungsring vorgesehen ist, dessen schrittweise Sperrfunktion durch Verzahnungsausbildung in der Programmnockentrommel aufhebbar ist. Zur Erzielung einer einfachen kompakten Bauform hat es sich als vorteilhaft erwiesen, wenn als Transportorgan gemeinsam über eine Schwinge betätigbare Stößel vorgesehen sind, von denen einer in Steuerabhängigkeit von dem Zeitgebernokcenrad und dem Zeitdehnungsring in die Verzahnung der Programmnockentrommel eingreift und ein anderer in Steuerabhängigkeit von dem Zeitgebernockenrad mit der Verzahnung des Zeitdehnungsringes in Eingriff kommt. Weiterhin ist es in dieser Richtung vorteilhaft, wenn der andere Stößel aus drei über ein Winkelteil in einer Wirkrichtung miteinander verbundenen Einzelstößel besteht. Weiterhin ist es hinsichtlich Bauaufwand und Größe vorteilhaft, wenn innerhalb der mit Innenverzahnung versehenen Programmnockentrommel die Verzahnung des Zeitdehnungsringes und des Zeitgebernockenrades mit dem Einfall der Stößel entsprechenden Steuerdurchbrüchen angeordnet ist.In a known program switching device of the type mentioned above (DE-OS 2 040 464), the time stretching ring is moved by the transport blade until stop cams are in contact with the program drum and take it with them until the teeth in the program drum are effective again. This means that the program drum only has to carry out so many steps until the time stretching ring is taken away by the program drum with a further stop. The invention is therefore based on the object of providing a program switching device of the type mentioned above, with which the step times specified by the timer can be multiplied on practically all cam drum positions using simple means and a simple structure. In a program switching device of the type mentioned above, this is achieved in a simple manner in that the time expansion ring is connected to the parts fixed to the housing in a spring-elastic manner counter to the transport direction. In this case, it is advantageous to obtain a defined long-term if the transport member can be brought into engagement with the toothing of the program cam drum depending on the timing cam wheel and the time expansion ring. The time expansion ring can be brought into the desired position by appropriately designing the spring force and the friction conditions. However, it is particularly advantageous to also use larger time-La 2 Syr / 13.07.1983 To overcome intervals against the spring force if a backstop is provided for the time expansion ring, the gradual locking function of which can be canceled by toothing formation in the program cam drum. In order to achieve a simple, compact design, it has proven to be advantageous if, as a transport element, plungers which can be actuated jointly via a rocker are provided, one of which engages in the toothing of the program cam drum in dependence on the timing of the timing cam wheel and the time expansion ring, and another in dependence on the timing of the timing cam wheel comes into engagement with the toothing of the time expansion ring. Furthermore, it is advantageous in this direction if the other plunger consists of three individual plungers which are connected to one another via an angular part in an effective direction. Furthermore, it is advantageous with regard to construction costs and size if the toothing of the time expansion ring and the timing cam wheel is arranged within the program cam drum provided with internal toothing with control openings corresponding to the tappet.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben und die Wirkungsweise näher erläutert.An exemplary embodiment according to the invention is described with reference to the drawing and the mode of operation is explained in more detail.

  • Fig. 2 eine Schnittdarstellung gemäß der Linie 11-11 nach Fig. 1.
Show it:
  • 1 is a schematic diagram of the program switching device according to the invention, partly in section,
  • 2 is a sectional view taken along the line 11-11 of FIG. 1st

Die Programmschalteinrichtung besteht aus einer Programmnockentrommel 1 und einem Zeitgebernockenrad 2, die beide als Hohltrommel ausgebildet sind, sowie einen gleichfalls als Nockenhohltrommel ausgebildeten Zeitdehnungsring 3. Die Nocken 4 arbeiten mit schematisch angedeuteten Nockenkontakten 5 zusammen. Die Programmnockentrommel 1 besitzt einen Lagerungsansatz 6, der in einer Frontplatine 7 drehbar gelagert ist. Auf der offenen Seite ist die Programmnockentrommel mit einem zylinderförmigen Ansatz 8 ausgestattet, auf dessen Außenseite das Zeitgebernockenrad 2 drehbar gelagert ist und auf dessen Innenseite eine Innenverzahnung 9 vorhanden ist. Innerhalb der Verzahnung 9 ist die Verzahnung 10 des Zeitgebernockenrades 2 und auch der Zeitdehnungsring 3 mit der Verzahnung 11 für den Transport und der Sperrverzahnung 12. Eine ringförmige Anformung 13 liegt zwischen der Innenverzahnung 9, der Programmnockentrommel 1 und einem ringförmigen Ansatz 14 der Verzahnung 10 des Zeitgebernockenrades 2. Zum Eingriff in die Verzahnungen kommen die Stößel 15 bis 19, die in der durch den motorisch angetriebenen Exzenter 20 um die Mittelachse 21 der Trommel schwenkbaren Schwinge 22 entgegen nicht näher dargestellten Federn verschiebbar gelagert sind. Die Stößel 16 und 19 sind über ein Winkelteil 23 in einer Wirkrichtung miteinander verbunden. Eine um den Bolzen 24 schwenkbar gelagerte Rückdrehsperre 25 wird von der sich gehäusefest abstützenden Zugfeder 26 in die Sperrverzahnung 12 im Zeitdehnungsring 3 eingedrückt, solange eine Verzahnung 27 in der Programmnockentrommel 1 mit diersr Verzahnung übereinstimmt. Ein Anschlag 28 am Zeitdehnungsring 3 begrenzt die Rückstellbewegung des Zeitdehnungsringes, der durch die Feder 29, die sich einerseits an einer Anformung 30 des Zeitdehnungsringes 3 und andererseits an einem gehäusefesten Vorsprung 31 als Zugfeder abstützt. Zur Funktion der erfindungsgemäßen Programmschalteinrichtung wird folgendes ausgeführt: Die Stößel 15, 16 und 17, die von der Verzahnung 10 des Zeitgebernockenrades 2 gesteuert werden, können - wie bisher - Positionswechsel der Programmnockentrommel durchführen. Die Stößel 18 und 19 sind für Langzeitschritte vorgesehen. Fällt nun der Stößel 16 durch den Steuerschlitz 32 der Verzahnung 10, so wird der Stößel 19 über das Winkelteil 25 zum Einfall in die Verzahnung 11 des Zeitdehnungsringes 3 freigegeben. Der Zeitring 3 wird hierdurch um eine Position in Drehrichtung vorwärts bewegt. Ist für die Rückdrehsperre 25 keine Verzahnung 27 in der Programmnockentrommel 1, so kann die Rückdrehsperre nicht in die Sperrverzahnung 12 einfallen, so daß kein Langzeitschritt erfolgt. Der Zeitdehnungsring 3 wird sodann durch die Zugfeder 29 entgegen der Drehrichtung bis zum Anschlag 28 zurückgeholt. Nach erfolgtem Langzeitschritt erfolgt der Transport der Programmnockentrommen, wenn der Zeitdehnungsring 3 soweit in Drehrichtung transportiert wurde, daß der Stößel 18 durch einen Steuerschlitz 33 im ringförmigen Ansatz 13 des Zeitdehnungsringes 3 zum Einfall in die Innenverzahnung 9 der Nockentrommel freigegeben wird, und zwar dann, wenn auch ein Steuerschlitz in der ringförmigen Anformung 14 des Zeitgebernockenrades 2 vorhanden ist. Sind am Zeitdehnungsring mehrere Steuerschlitze nacheinander angeordnet, können beispielsweise drei 12-Minuten-Schritte nacheinander bzw. ein 36-Minuten-Schritt an der Nockentrommel durchgeführt werden. Die Ausbildung dieser Schritte ist vom Federvolumen der Zugfeder 29 abhängig. Die Rückdrehsperre wird aufgehoben, wenn durch die Verzahnung 27 der Programmnockentrommel die Rückdrehsperre 25 aus der Sperrverzahnung 12 herausgehoben wird. Der Stößel 18 wird in die Schwinge durch einen entsprechenden Steg der ringförmigen Anformung 14 in die Schwinge entgegen der Kraft der den Stößel beaufschlagenden Feder zurückgedrückt.The program switching device consists of a program cam drum 1 and a timer cam wheel 2, both of which are designed as a hollow drum, and a time also designed as a hollow cam drum Expansion ring 3. The cams 4 work together with schematically indicated cam contacts 5. The program cam drum 1 has a bearing attachment 6 which is rotatably mounted in a front plate 7. On the open side, the program cam drum is equipped with a cylindrical extension 8, on the outside of which the timing cam wheel 2 is rotatably mounted and on the inside of which there is an internal toothing 9. Within the toothing 9 is the toothing 10 of the timing cam wheel 2 and also the time expansion ring 3 with the toothing 11 for the transport and the locking toothing 12. An annular projection 13 lies between the internal toothing 9, the program cam drum 1 and an annular shoulder 14 of the toothing 10 of the Timing cam wheel 2. To engage the teeth, the tappets 15 to 19, which are displaceably mounted in the rocker arm 22, which can be pivoted about the central axis 21 of the drum by the motor-driven eccentric 20, against springs not shown in detail. The plungers 16 and 19 are connected to one another in an effective direction via an angle part 23. A backstop 25 pivotally mounted about the pin 24 is pressed into the locking toothing 12 in the time expansion ring 3 by the tension spring 26 which is fixed to the housing, as long as a toothing 27 in the program cam drum 1 matches the toothing. A stop 28 on the time expansion ring 3 limits the return movement of the time expansion ring, which is supported by the spring 29, which is supported on the one hand on a molded part 30 of the time expansion ring 3 and on the other hand on a projection 31 fixed to the housing as a tension spring. The following is carried out for the function of the program switching device according to the invention: The plungers 15, 16 and 17, which are controlled by the toothing 10 of the timing cam wheel 2, can - as before - carry out a position change of the program cam drum. The plungers 18 and 19 are intended for long-term steps. Now falls Tappet 16 through the control slot 32 of the toothing 10, the tappet 19 is released via the angle part 25 for incidence in the toothing 11 of the time expansion ring 3. The time ring 3 is thereby moved forward by one position in the direction of rotation. If there is no toothing 27 in the program cam drum 1 for the reversing lock 25, the reversing lock cannot engage in the locking toothing 12, so that no long-term step takes place. The expansion ring 3 is then brought back by the tension spring 29 against the direction of rotation up to the stop 28. After the long-term step has taken place, the program cam turrets are transported when the time expansion ring 3 has been transported so far in the direction of rotation that the plunger 18 is released through a control slot 33 in the annular extension 13 of the time expansion ring 3 for engagement in the internal toothing 9 of the cam drum, specifically when there is also a control slot in the annular projection 14 of the timing cam wheel 2. If several control slots are arranged one after the other on the time expansion ring, three 12-minute steps in succession or one 36-minute step can be carried out on the cam drum, for example. The formation of these steps depends on the spring volume of the tension spring 29. The backstop is released when the backstop 25 is lifted out of the locking toothing 12 by the teeth 27 of the program cam drum. The plunger 18 is pressed back into the rocker by a corresponding web of the annular formation 14 in the rocker against the force of the spring acting on the plunger.

Die erfindungsgemäße Ausbildung der Programmsteuereinrichtung mit einer relativ großen Anzahl von Stößeln hat gegenüber der Nutzung eines Stößels als Stößel, der sowohl durch die Verzahnung des Zeitgebernockenrades als auch des Zeitdehnungsringes zum Transport der Programmnockentrommel hindurchgreift, den Vorteil, daß wahlweise je nach Verzahnungsausbildung 34 und 35 der Innenverzahnung 9 in der Programmnockentrommel auf einer Position wahlweise z.B. ein 12-Minuten-Schritt oder ein 20-Minuten-Schritt an der Nockentrommel gemacht werden kann. Dies kann folgendermaßen vor sich gehen: Ist für den Stößel 18 eine Verzahnung 34 vorhanden, erfolgt ein 12-Minuten-Schritt. Ist kein Zahn der Verzahnung 34 vorhanden, wird der Zeitdehnungsring 3 mit dem Stößel 19 weitertransportiert, bis der Stößel 19 durch einen Durchbruch im Zeitdehnungsring 3 auf die Nockentrommel-Verzahnung 35 trifft. Damit erfolgt ein 20-Minuten-Schritt.The inventive design of the program control device with a relatively large number of plungers has the advantage over the use of a plunger as a plunger, which engages both through the toothing of the timing cam wheel and the time expansion ring for transporting the program cam drum, that either 34 and 35 depending on the toothing design Internal teeth 9 A 12-minute step or a 20-minute step on the cam drum can be made in one position in the program cam drum. This can be done as follows: If there is a toothing 34 for the tappet 18, a 12-minute step takes place. If there is no tooth of the toothing 34, the time expansion ring 3 is transported further with the tappet 19 until the tappet 19 hits the cam drum toothing 35 through an opening in the time expansion ring 3. This takes a 20-minute step.
