Description

Rundstrickmaschine mit elektronischem Zähler Bei der Verwendung von Zählwerken für Rundstrickmaschinen muss eine hohe Ablesegeschwindigkeit und absolute Genauigkeit gefordert werden. Dies gilt insbesondere dann, wenn die Zählwerke zur Steuerung einer Ablesevorrichtung_für ein mehrfarbiges Muster dienen. Circular knitting machine with electronic counter When using counters for circular knitting machines, a high reading speed and absolute accuracy must be required. This is especially true when the counters are used to control a reading device for a multicolored pattern.

Mechanische Zähler sind für den genannten Fall zu langsam. Von den elektronischen Zählern sind unter anderem z.B. die Analogzähler ungeignet, da sie bei Spannungs - und Frequenz-Schwankungen zu Fehlmessungen neigen.Mechanical counters are too slow for this case. Of the Electronic meters, for example, analog meters are unsuitable because they tend to incorrect measurements in the event of voltage and frequency fluctuations.

Nach der Erfindung werden daher nur derartige elektronische Zähler verwendet, die von Spannungs - und Frequenzschwankungen unabhängig sind» Hierzu sind insbesondere Flip - Flop Zähler besonders geeignet.According to the invention, therefore, only such electronic counters are used that are independent of voltage and frequency fluctuations »For this purpose flip-flop counters are particularly suitable.

Das Prinzip der elektronischen Zähler ist bekannt und z.B. in '1,Brockhaus der Naturwissenschaften , 1965, Seite 15o " beschrieben. Der Flip - Flop Zähler ist im selben Werk auf Seite 192 näher erläutert . Tatsächlich sind aber derartige Zähler seit zwanzig Jahren bekannt, ohne dass sie im Strickmaschinenbau verwendet worden wären. Dabei ist das Grundprinzip verhältnismässig einfach.The principle of electronic counters is known and is described, for example, in '1, Brockhaus der Naturwissenschaften , 1965, page 150 ". The flip-flop counter is explained in more detail in the same work on page 192. In fact, such counters have been known for twenty years without that they would have been used in knitting machine construction, although the basic principle is relatively simple.

Beim elektronischen Zähler legen die zu zählenden Stromstösse z.B, einen elektrischen Kippschalter abwechselnd in die eine Kippstellung ( 1 ) und zurück in die andere ( o ) . Nur beim Zurücklegen, also bei jedem zweiten Stromstoss, wird ein neuer Stromstoss erzeugt und an einen weiteren Kippschalter geleitet, so dass die ursprüngliche Frequenz halbiert wird. Das Zählergebnis am Ende der Stromstossfolge ist an der Stellung der Kippschalter im Dualsystem abzulesen. Bei Anwendung des Dezimalsystems werden Vierergruppen von Kippschaltern auf null zurückgestellt, sobald die zehnte Stellung erreicht ist.With the electronic meter, the current impulses to be counted are e.g. an electric toggle switch alternately to one of the tilt positions (1) and back in the other (o). Only when moving back, i.e. with every second power surge, will a new power surge generated and to another toggle switch so that the original frequency is halved. The counting result on The end of the current surge sequence can be read from the position of the toggle switch in the dual system. Using the decimal system, groups of four toggle switches are set to zero reset as soon as the tenth position is reached.

Die spezielle Ausführung eines Flip - Flop Zählers kann beispielsweise aus zwei zusammengeschalteten Elektronenröhren bestehen, von denen die eine ständig Anodenstrom führt ; dieser stabile Zustand kann schnell zwischen den Röhren gewechselt werdenThe special design of a flip-flop counter can, for example consist of two electron tubes connected together, one of which is constantly Anode current leads; this stable state can be changed quickly between the tubes will
