Die Behandlung des Fotomaterials mit den verschiedenen Behandlungslösungen erfolgt mit Maschinen.The treatment of the photographic material with the various treatment solutions is done with machines.

Dazu wird das Fotomaterial im Fall von Rollenware, z.B. mit Hilfe eines Schleppbandes, durch die verschiedenen Tanks mit den Verarbeitungslösungen gezogen.For this purpose, the photo material in the case of roll goods, for example with the aid of a drag belt, is pulled through the various tanks with the processing solutions.

Bei einer anderen Lösung, die auch im Falle von Blattware angewendet wird, wird das Fotomaterial durch angetriebene Walzenpaare durch die Lösungen transportiert. Die Walzenpaare sind meist zu Gruppen zusammengefaßt in einem sogenannten Rack, das aus dem Tank herausnehmbar ist.In another solution, which is also used in the case of sheet goods, the photo material is transported through the solutions by driven roller pairs. The roller pairs are usually grouped together in a so-called rack that can be removed from the tank.

Ziel der Konstrukteure war es bislang, den Übergang und die Umlenkung des Fotomaterials von einem Tank zum anderen so kurz wie möglich zu konstruieren, um die Zeit , die das Fotomaterial in dem Chemikalienbad verweilt, so lang wie möglich und die Zeit außerhalb des Chemikalienbades, die als nicht effektiv fuhr die Verarbeitung angesehen wurde, so kurz wie möglich zu gestalten.The goal of the designers so far has been to design the transition and the diversion of the photo material from one tank to the other as short as possible, in order to keep the time that the photo material remains in the chemical bath as long as possible and the time outside the chemical bath processing was considered ineffective to keep it as short as possible.

Auch sind manche Entwickler- und Umkehrbad-Lösungen so oxidationsempfindlich, daß bei längeren Umlenkzeiten bereits deutliche sensitometrische Nachteile, wie eine Erhöhung des Entwicklungsschleiers, auftreten können.Also, some developer and reversal bath solutions are so sensitive to oxidation that with longer deflection times, clear sensitometric disadvantages, such as an increase in the development veil, can occur.

Dieses Problem ist jedoch in den letzten Jahren durch erhebliche Fortschritte in Bezug auf den Oxidationsschutz der fotografischen Lösungen aus geräumt worden.However, this problem has been resolved in recent years with significant advances in the oxidation protection of photographic solutions.

Nachteilig ist jedoch die durch den kurzen Umlenkungsweg bedingte, starke Verschleppung von Chemikalien von einem Behandlungstank in den nächsten.A disadvantage, however, is the strong carryover of chemicals from one treatment tank to the next due to the short deflection path.

Aufgabe der Erfindung war es, diese Chemikalienverschleppung weitgehend zu vermeiden.The object of the invention was to largely avoid this carryover of chemicals.

Diese Aufgabe wird mit überraschend einfachen Mitteln in überraschend großem Maße gelöst werden.This task will be solved to a surprisingly large extent with surprisingly simple means.

Gegenstand der Erfindung ist eine Entwicklungsmaschine aus mehr als einem Tank und Mitteln, die kontinuierlichen Transport des fotografischen Materials durch die Entwicklungsmaschine ermöglichen, bei der die Übergabestrecke von einen Tank zum anderen 40-200 cm, bevorzugt 60-120 cm, beträgt. Auf dieser Strecke wird das Fotomaterial von anhaftenden Chemikalien durch Abtropfen und gegebenenfalls durch geringen Antrag von Wasser, das nicht dem Abwasser zugeführt wird, sondern in den Tank, aus dem das Fotomaterial gerade kommt, zurückgeführt wird, befreit. Die Wasserantragsmenge beträgt vorzugsweise 30 bis 150 ml/m². Das fotografische Material wird insbesondere mit einer Geschwindigkeit von 1 bis 20 m/min transportiert.The invention relates to a developing machine comprising more than one tank and means which enable the photographic material to be transported continuously through the developing machine, in which the transfer distance from one tank to another is 40-200 cm, preferably 60-120 cm. On this route, the photographic material is drained of any chemicals that may adhere and, if necessary freed from water, which is not supplied to the wastewater, but is returned to the tank from which the photographic material just came. The amount of water applied is preferably 30 to 150 ml / m². The photographic material is transported in particular at a speed of 1 to 20 m / min.

Die Übergabestrecke wird im Prinzip mit den selben Racks gestaltet, wie sie zum Transport des Fotomaterials durch die Tanks verwendet werden. Nur werden diese Racks (evtl. in verkürzter Form) jetzt um 180° gedreht auf die Tankwand zwischen zwei Tanks aufgesetzt.In principle, the transfer route is designed with the same racks as are used to transport the photo material through the tanks. Only these racks (possibly in a shortened form) are now rotated by 180 ° and placed on the tank wall between two tanks.

Durch diese Vorrichtung wird die Verschleppung der Chemikalien in den nächsten Tank weitgehend verhindert. Ein Ausgleich für die durch das zulaufende Wasser eintretende Verdünnung, erfolgt durch Einsatz entsprechend höher konzentrierter Regeneratoren bis hin zur Zugabe reiner Chemikalien in fester Form zur Rejuvenierung.This device largely prevents chemical carryover into the next tank. Compensation for the dilution caused by the incoming water is achieved by using correspondingly more concentrated regenerators up to the addition of pure chemicals in solid form for rejuvenation.

Fig. 1 zeigt einen schematischen Aufbau einer Entwicklungsmaschine mit einer konventionellen Übergabestrecke und einer Übergabestrecke nach der Erfindung.Fig. 1 shows a schematic structure of a developing machine with a conventional transfer line and a transfer line according to the invention.

Fotomaterial (1) wird mittels Transportwalzen (2) durch die Tanks (3) geführt. Die Transportwalzen (2) sind an einem Rack (8) befestigt, das den jeweiligen Tank in zwei Hälften trennt.Photographic material (1) is guided through the tanks (3) by means of transport rollers (2). The transport rollers (2) are attached to a rack (8) that separates the respective tank in half.

Zwischen dem ersten und dem zweiten Tank ist eine konventionelle Übergabestrecke, geschützt durch das Leitblech (4), vorgesehen, zwischen dem zweiten und dem dritten Tank eine Übergabestrecke nach der Erfindung, die aus einem auf die Wand zwischen den beiden Tanks gesetzten Rack (6) mit Walzenpaaren besteht. An der mit (7) bezeichneten Stelle kann Wasser angetragen werden.A conventional transfer section, protected by the guide plate (4), is provided between the first and the second tank, and a transfer section according to the invention, which consists of a rack (6) placed on the wall between the two tanks, between the second and the third tank. with pairs of rollers. Water can be applied at the point marked (7).

Beispiel 1example 1

Die Wirksamkeit der erfindungsgemäßen Vorrichtung kann wie folgt demonstriert werden.The effectiveness of the device according to the invention can be demonstrated as follows.

Es wird ein handelsübliches Color-Fotopapier in einem Entwickler folgender Zusammensetzung entwickelt: CD 3 10 g/l Natriumsulfit 1 g/l Benzylalkohol 10 ml/l Polyglycol 20 ml/l Monokaliumphosphat 17 g/l pH 11,4, mit KOH eingestellt. A commercially available color photo paper is developed in a developer of the following composition: CD 3 10 g / l Sodium sulfite 1 g / l Benzyl alcohol 10 ml / l Polyglycol 20 ml / l Monopotassium phosphate 17 g / l pH 11.4, adjusted with KOH.

Im Anschluß an die Entwicklung wird das Fotomaterial in einem Wassertank gewässert, anschließend bleichfixiert, gewässert und getrocknet.Following the development, the photographic material is washed in a water tank, then bleach-fixed, washed and dried.

Durch die Einschleppung von anhaftendem Entwickler steigt der pH-Wert in dem Wässerungstank an.The pH value in the washing tank rises due to the introduction of adhering developer.

Es ist daher möglich, durch Messung des pH-Wertes in dem Wassertank nach dem Entwickler, den Grad der Entwicklerverschleppung zu bestimmen, sofern das System geeicht ist.It is therefore possible, by measuring the pH in the water tank after the developer, to determine the degree of developer carryover if the system is calibrated.

a) (Vergleich)a) (comparison)

7 m² handelsübliches Colorpapier wurden in Form von 8,9 cm breiter Rollenware in einer Entwicklungsmaschine entwickelt. Papiervorschub 1,5 m/min Entwicklertemperatur 38°C Entwicklungszeit 45 sek Entwickler wie vorstehend. 7 m² of commercial color paper was developed in the form of 8.9 cm wide rolls in a developing machine. Paper feed 1.5 m / min Developer temperature 38 ° C Development time 45 sec developer as above.

Nach dem Entwickler durchlief das Papier einen mit Wasser gefüllten Tank mit 8 l Inhalt. Es erfolgte kein Frischwasserzulauf. Die Übergabestrecke vom Entwicklertank zum Wässerungstank betrug 15 cm.After the developer, the paper went through a water-filled tank with 8 liters. There was no fresh water supply. The transfer distance from the developer tank to the washing tank was 15 cm.

Nach Durchlauf der 7 m² wurde der pH-Wert im Wässerungstank gemessen: pH 10,3.After passing through the 7 m², the pH in the washing tank was measured: pH 10.3.

Gemäß der "Eichtabelle" entspricht das einem Gehalt von mehr als 5 Gew.-% CD 3 im Wasser. Daraus errechnet sich eine Verschleppung von ca. 60 ml/m².According to the "calibration table", this corresponds to a content of more than 5% by weight of CD 3 in the water. This translates into a carryover of approx. 60 ml / m².

b) (Erfindungsgemäß)b) (According to the invention)

Es wird wie unter a) verfahren, jedoch wird das Fotomaterial über die erfindungsgemäße Übergabestrecke geleitet (Länge 55 ccm) und am aufsteigenden Teil mit 60 ml Wasser/m² gleichmäßig beaufschlagt.The procedure is as under a), but the photographic material is passed over the transfer section according to the invention (length 55 ccm) and is evenly charged with 60 ml of water / m 2 on the rising part.

Erst danach gelangt das Material in den Wässerungstank.Only then does the material get into the washing tank.

Nach Durchlauf von 7 m² wurde erneut der pH-Wert in dem Wassertank gemessen: pH 8,3.After running through 7 m², the pH in the water tank was measured again: pH 8.3.

Das entspricht ca. einer 1 gew.-%igen CD 3-Konzentration im Wasser. Durch die erfindungsgemäße Maßnahme wird demnach die Verschleppung um ca. 80 % vermindert.This corresponds approximately to a 1% by weight CD 3 concentration in the water. The measure according to the invention accordingly reduces the carry-over by approximately 80%.

Beispiel 2Example 2 a) (Vergleich)a) (comparison)

Das gleiche Fotomaterial wie im Beispiel 1 wird durch ein Bleichfixierbad geleitet.The same photographic material as in Example 1 is passed through a bleach-fix bath.

Zusammensetzungcomposition

Ammonium Eisen EDTAAmmonium iron EDTA 50 g/l50 g / l AmmoniumthiosulfatAmmonium thiosulfate 110 g/l110 g / l NatriumsulfitSodium sulfite 25 g/l25 g / l pH 6,5.pH 6.5.

Nach dem Bleichfixieren gelangt das Material unmittelbar in einen 8-l-Wässerungstank. Die Übergabestrecke beträgt 15 cm vom Bleichfixierbadniveau bis zum Wasserniveau.After fixing the bleach, the material immediately goes into an 8-liter washing tank. The transfer distance is 15 cm from the bleach-fix bath level to the water level.

Nach Verarbeitung von 10 m² Colorpapier wird aus dem Wassertank eine Probe entnommen und analytisch der Thiosulfatgehalt bestimmt: 9,5 g/l.After processing 10 m² of color paper, a sample is taken from the water tank and the thiosulfate content is determined analytically: 9.5 g / l.

b) (Erfindungsgemäß)b) (According to the invention)

Es wird wie in Beispiel 1b) das Papier über eine Übergabestrecke von 55 cm geleitet und am aufsteigenden Teil gleichmäßig mit 70 ml Wasser pro m² beaufschlagt.As in Example 1b), the paper is passed over a transfer distance of 55 cm and evenly treated with 70 ml of water per m 2 on the rising part.

Danach läuft das Material in den Wassertank (Inhalt 8 l). Nach Verarbeitung von 10 m² wird erneut eine Probe entnommen und analytisch der Thiosulfatgehalt bestimmt: Ergebnis 2,1 g/l. Durch die erfindungsgemäße Vorrichtung wird demnach die Verschleppung um wenistens den Faktor 4 vermindert.Then the material runs into the water tank (capacity 8 l). After processing 10 m², another sample is taken and the thiosulfate content is determined analytically: result 2.1 g / l. The carry-over is therefore reduced by a factor of at least 4 by the device according to the invention.

In der Praxis wird das zur "Vorreinigung" des Fotomaterials verwendete Wasser zweckmäßigerweise aus dem nachfolgenden Wassertank entnommen.In practice, the water used for " pre-cleaning " the photographic material is expediently taken from the subsequent water tank.
