Verfahren zur Dosierung der Regeneratorlösung bei photographischen EntwicklungsmaschinenMethod for metering the replenisher solution in photographic applications Developing machines

Die Erfindung betrifft ein Verfahren zur Dosierung der Regeneratorlösung bei photographischen Entwicklungsmaschinen. The invention relates to a method for dosing the Regenerator solution in photographic processing machines.

Die bekannten photographischen Entwicklungsmaschinen dienen zur Entwicklung des latenten Bildes belichteter photographischer Schichten. Bei diesem Prozess wird Silberhalogenid zu metallischem Silber reduziert, wobei ein Verbrauch an reduzierender Substanz der Entwicklerlösung unter gleichzeitiger Anreicherung der Lösung mit dem frei werdenden Halogenid erfolgt. Zur Durchführung einer kontinuierlichen oder serienweisen Entwicklung von Filmen unterschiedlicher Formate und verschiedenen Schwärzungsgrades ist es erforderlich, dem Entwicklerbad jeweils eine dem tatsächlichen Verbrauch entsprechende Menge einer Regeneratorlösung zuzuführen und;den Überschuß an verbrauchter Lösung ablaufen zuThe known photographic developing machines are used to develop the latent image of exposed photographic machines Layers. In this process, silver halide is reduced to metallic silver, with a consumption of reducing substance of the developer solution with simultaneous enrichment of the solution with the released Halide takes place. To carry out a continuous or serial development of films of different Formats and different degrees of blackening, it is necessary to supply the developer bath with an amount of a regenerator solution corresponding to the actual consumption and; the excess of used solution to run off

lassen. Solche Regeneratorlösungen unterscheiden sich von " den Stamm-Entwicklerlösungen dadurch, daß sie einen erhöhten Gehalt an reduzierenden Substanzen und einen verminderten Gehalt an Bromiden aufweisen.permit. Such regenerator solutions differ from " the stock developer solutions in that they have an increased content of reducing substances and a decreased content Have bromide content.

Der tatsächliche Entwicklerverbrauch hängt im wesentlichen von drei Komponenten ab:The actual developer consumption essentially depends on three components:

1. von der Filmflächengröße;1. the size of the film area;

2. vom mittleren integralen Schwärzungsgrad des entwickelten Bildes und2. the mean integral density of the developed image and

3. von sonstigen oxydierenden Einflüssen, z.B. durch Luftsauerstoff.3. from other oxidizing influences, e.g. by Atmospheric oxygen.

Es ist bekannt, daß Einwirkungen gemäß 3. auf ein vernachlässigbares Minimum herabgedrückt werden können, indem entweder ein nicht luftempfindlicher Entwickler verwendet oder ein hermetischer Luftabschluß vorgesehen wird. Ein solcher Luftabschluß ist durch DBGM... (K 55 469/57c) bekannt geworden.It is known that actions according to 3. on a negligible Minimum can be suppressed by using either a non-air sensitive developer or a hermetic air seal is provided. Such an air seal is possible by DBGM ... (K 55 469 / 57c) known.

Die beiden anderen, den Entwicklerverbrauch beeinflussenden Komponenten unterscheiden sich insofern, als sich die Filmfläche durch geeignete Maßnahmen bereits vor oder bei Beginn des Entwicklungsvorganges erfassen läßt, während die Bestimmung des Schwärzungsgrades oder des Entwicklerverbrauchs naturgemäß erst nach Abschluß des Entwicklungsvorgangs eingeleitet werden kann. The other two components that influence developer consumption differ in that the film area is different can be captured by suitable measures before or at the beginning of the development process, while the Determination of the degree of blackening or the developer consumption can naturally only be initiated after the development process has been completed.

Einrichtungen zur automatischen Flächenbestimmung des einlaufenden Films sind zwar bisher bei Entwicklungsmaschinen nicht üblich, da man meist nur die Einlauflänge abtastet. Eine Berücksichtigung der Filmbreite ist aber in einfacher Weise möglich, nämlich durch vorzugsweise hin- und herlaufende Abtastelemenre, wie Mikroschalter oder mit Infrarot beaufschlagte Photozellen.Devices for the automatic determination of the area of the incoming Up to now, films have not been used in developing machines, since mostly only the infeed length is scanned. However, the film width can be taken into account in a simple manner, namely by preferably moving back and forth Scanning elements, such as microswitches or infrared photocells.

Der Erfindung liegt die Aufgabenstellung zugrunde, Regeneratorlösung zur Entwicklerlösung einer Entwicklungsmaschine vollautomatisch und derart streng verbrauchsabhängig zuzugeben, daß die Entwicklungsergebnisse über einen nahezu unbegrenzten Zeitraum bei beliebiger Auslastung der Maschine konstant bleiben.The invention is based on the problem of regenerator solution to be added to the developer solution of a developing machine fully automatically and so strictly depending on consumption, that the development results over an almost unlimited period of time with any utilization of the machine stay constant.

Diese Aufgabe ist mit einem Verfahren gelöst, das dadurch gekennzeichnet ist, daß einer an sich bekannten, zur Filmfläche proportionalen Regelung der Regeneratormenge eine zum tatsächlichen Verbrauch proportionale Regelung auf Grundlage der durch periodische an sich bekannte chemische Maßanalyse zu bestimmenden Änderung des Halogenidgehalts der Entwickl'erlösung überlagert bzw. zugeordnet wird.This object is achieved with a method that thereby is characterized in that a known, to the film area proportional control of the amount of regenerator Regulation proportional to the actual consumption based on the chemical known per se from periodic Dimensional analysis to be determined change in the halide content of the developer solution is superimposed or assigned.

Der Erfindung liegt somit der Gedanke zugrunde, einer Vordosierung der Regeneratorlösung nach der Fläche des einlaufenden Films eine verbrauchsabhängige Korrekturgröße zu überlagern, die durch periodische chemische AnalyseThe invention is thus based on the idea of predosing the regenerator solution according to the area of the incoming Films is a consumption-dependent correction variable overlay that by periodic chemical analysis

(Titrieren) des Entwicklerbades ermittelt wird.(Titration) of the developer bath is determined.

Objekt der maßanalytischen Bestimmung ist dabei der Halogenidgehalt der Entwicklerlösung. Maßgebend für die Wahl der Halogenidbestimmung ist dabei, daß die beim Entwicklungsprozeß aus der photographischen Schicht in die Entwicklerlösung gelangende Halogenidmenge streng proportional ist, der durch Reduktion in der Schicht gebildeten Silbermenge. Außer dem Vorteil der genauen Proportionalität besteht der Vorteil, daß es für Halogenide äußerst empfindliche, quantitative Analysenmöglichkeiten durch Titration mit potentiometrischer Endpunktbestimmung gibt.The object of the dimensional analysis is the halide content of the developer solution. Relevant for the The choice of halide determination is that of the development process from the photographic layer The amount of halide entering the developer solution is strictly proportional to that due to reduction in the layer amount of silver formed. In addition to the advantage of precise proportionality, there is the advantage that it is used for halides extremely sensitive, quantitative analysis options by titration with potentiometric endpoint determination.

Für das Zusammenwirken dieser Elemente wird vorgeschlagen, Laufzeit und/oder Förderleistung der Regeneratorzuführpumpe regelbar zu machen. Man kann beispielsweise eine solche Anordnung vorsehen, daß vollautomatisch die Pumpenlaufzeit proportional zur Filmfläche geregelt wird, und daß ebenfalls automatisch die Durchflußmenge proportional zu dem vom Analysengerät festgestellten Halogenidüberschuß der Entwicklerlösung gegenüber dem Normalwert gesteigert oder vermindert wird.For the interaction of these elements, it is proposed to set the running time and / or delivery rate of the regenerator feed pump to make controllable. One can, for example, provide such an arrangement that the pump running time is fully automatic is controlled proportionally to the film area, and that also automatically proportional to the flow rate to the excess halide of the developer solution determined by the analyzer compared to the normal value is increased or decreased.

Verhältnismäßig einfach ist dies so zu realisieren, daß mindestens drei für verschiedene Fördermenge voreingestellteThis is relatively easy to implement in such a way that at least three are preset for different delivery rates

../5 90988 1/0727 ../5 90988 1/0727

Durchflußregler vorgesehen werden und daß über mehrere Magnetventile oder einen Dreiwegehahn der Regeneratorzufluß jeweils über einen dieser Regler geleitet wird, nämlich derart, daß bei normalem Halogenidgehalt die normale Regeneratormenge je Flächeneinheit zufließt, bei erhöhtem Halogenidgehalt eine größere und bei vermindertem Halogenidgehalt eine kleinere. Eine gleichartige Funktion ist natürlich auch mit einem fernverstellbaren Durchflußregler, einem Pumpengeschwindigkeitsregler oder einer zusätzlichen Laufzeitregelung zu erzielen. Man kann auch die Filmflächenbestimmung so ausbilden, daß flächenproportionale Impulszahlen gebildet werden, die elektronisch mit einem vom Analysengerät gelieferten Kennwert des Halogenidgehalts multipliziert werden und daß das Produkt die Förderleistung des Regeneratorzuführungssystems steuert, In jedem Fall ist klar, daß für die Filme, die etwa bei Arbeitsbeginn bereits vor dem Vorliegen eines Analysenergebnisses entwickelt werden, die normale Regenerierungsquote wirksam wird. Flow regulators are provided and that over several Solenoid valves or a three-way valve the regenerator inflow is passed through one of these controllers, namely in such a way that with a normal halide content the normal amount of regenerator per unit area flows in at a larger halide content and a smaller one with a reduced halide content. A similar function is of course also available with a remotely adjustable flow regulator, to achieve a pump speed controller or an additional runtime control. One can also train the film area determination so that area-proportional pulse numbers are formed that electronically be multiplied by a characteristic value of the halide content supplied by the analyzer and that the product controls the feed rate of the replenisher supply system, in any case it is clear that for the films that are approximately at Work can be developed before the result of an analysis is available, the normal regeneration rate becomes effective.

Natürlich kann man die normale Regenerierungsquote auch umschaltbar machen, z.B. höher für die Entwicklung von Negativen, niedriger für die Entwicklung von Positiven.Of course you can also use the normal regeneration rate make switchable, e.g. higher for the development of negatives, lower for the development of positives.
