Abstract

A wet treatment device, consisting of a plurality of liquid tanks, for photographic layer supports which can be moved through the liquid tanks by means of a transport device, wherein tank surfaces can be covered by lid parts against a place where the wet treatment device is set up, is designed in such a way that a common cover (12), reaching over the lid parts (11), for the tanks (2 to 5) is made of heat- insulating material or constructed as a hollow body (12b, 12c) and includes an insulating layer (13). This provides a hermetic seal and a temperature insulation of the tanks from the place where they are set up, avoiding the formation of condensate water and chemicals vapour, and at the same time greatly reducing the oxidation of the treatment solutions and moreover preventing an escape of chemicals vapours into the place where they are set up. <IMAGE>

Description

Die Erfindung betrifft eine aus mehreren Flüssigkeits­tanks bestehende Naßbehandlungsvorrichtung für fotogra­fische Schichtträger, welche durch die Flüssigkeits­tanks mittels einer Transportvorrichtung bewegbar sind, wobei Tankoberflächen durch Deckelteile gegen einen Aufstellraum für die Naßbehandlungsvorrichtung abdeck­bar sind.The invention relates to a wet treatment device for photographic substrates which consists of several liquid tanks and which can be moved through the liquid tanks by means of a transport device, tank surfaces being coverable by cover parts against an installation space for the wet treatment device.

Im wesentlichen eben über Behandlungstanks liegende Ge­häuseteile, die zur Füllung, Entleerung oder Reinigung der Tanks als abnehmbare Deckel ausgebildet sind, haben die Nachteile, daß sich über den Tanks und unter dem oder den Deckeln Chemikaliendämpfe und an der Deckelin­nenseite Kondenswasser bilden. Hierdurch wird einer­seits die Oxydation der Behandlungsflüssigkeit in uner­ wünschter Weise beschleunigt, andererseits treten die Dämpfe auch in den Aufstellraum der Vorrichtung aus und führen zu einer Geruchsbelästigung. Die Kondenswasser­bildung kann beim Abnehmen des Deckels zum Abtropfen des Kondenswassers im Aufstellraum führen.Housing parts which are located just above treatment tanks and are designed as removable covers for filling, emptying or cleaning the tanks have the disadvantages that chemical vapors form above the tanks and under the cover or covers and condensation water forms on the inside of the cover. On the one hand, this causes the oxidation of the treatment liquid to be reduced accelerated desirable, on the other hand, the vapors also escape into the installation room of the device and lead to an unpleasant smell. The formation of condensation can cause the condensation in the installation room to drip when the cover is removed.

Es sind auch sogen. Druckkammern als Naßbehandlungsvor­richtungen bekannt, beispielsweise durch die DE-PS 35 35 980 oder die DE-OS 32 30 175, durch die die Schichtträger auf einer überwiegend in horizontaler Richtung verlaufenden Bahn hindurchtransportiert werden und in die die Behandlungsflüssigkeit unter Druck, meist von oben und unten, eingepumpt wird. Hierbei ist es möglich, den als abnehmbaren Deckel ausgebildeten oberen Kammerteil so zu formen, daß er Transportwalzen teilweise umschließt und zwischen diesen in die Behand­lungsflüssigkeit eintaucht, so daß eine Oxydation der Behandlungsflüssigkeit und eine Kondenswasserbildung am Deckel in diesem Bereich vermieden wird. Dies ist je­doch in der Regel nicht im Ein- und Ausführbereich des Schichtträgers, der über der Behandlungsflüssigkeit liegen muß, möglich. Außerdem ist diese Ausgestaltung nicht bei Behandlungstanks anwendbar, durch die Schichtträger jedenfalls in erheblichem Umfang auch vertikal, z.B. auf einer U-förmigen oder einer U-wel­lenförmigen Bahn, transportiert werden. Hier muß immer zwischen der Abdeckung und der Flüssigkeitsoberfläche ausreichender Raum zum Einführen, Ausführen und einem hierbei erforderlichen Umlenken der zu behandelnden Schichtträger vorhanden sein, wobei dann eine raschere Oxydation, eine Kondensatbildung und außerdem der Aus­tritt von Chemikaliengerüchen in den Außenraum die Fol­ ge sind. Es ist zwar dabei schon bekannt, z.B. durch die DE-OS 34 28 361, vor oder nach Naßbehandlungsein­richtungen an den Durchführungsschlitzen für die Schichtträger Abstreifer, Verschlußlappen, Absaugein­richtungen oder ähnliche Schleusen für Flüssigkeiten und Dämpfe vorzusehen. Diese verhindern aber den Aus­tritt von Feuchtigkeit und Gerüchen eben nur direkt an den Durchführungsschlitzen und nicht über den Tanks und können auch die Oxydation und Kondensatbildung der Flüssigkeiten nicht verhindern.There are also so-called Pressure chambers known as wet treatment devices, for example by DE-PS 35 35 980 or DE-OS 32 30 175, through which the layer supports are transported on a predominantly horizontal path and into which the treatment liquid is under pressure, mostly from above and below , is pumped in. It is possible to shape the upper chamber part, which is designed as a removable cover, in such a way that it partially surrounds transport rollers and dips between them into the treatment liquid, so that oxidation of the treatment liquid and condensation on the cover in this area are avoided. However, this is generally not possible in the insertion and exit area of the layer support, which must lie above the treatment liquid. In addition, this embodiment is not applicable to treatment tanks, through which layer supports are in any case also transported to a considerable extent vertically, for example on a U-shaped or a U-wave-shaped path. There must always be sufficient space between the cover and the liquid surface for insertion, execution and a necessary redirection of the substrates to be treated, with faster oxidation, condensate formation and also the escape of chemical odors into the exterior are. Although it is already known, for example from DE-OS 34 28 361, to provide wipers, sealing flaps, suction devices or similar locks for liquids and vapors before or after wet treatment devices on the lead-through slots for the layer supports. However, these only prevent the escape of moisture and odors directly at the feed-through slots and not above the tanks and cannot prevent the liquids from being oxidized and condensed.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einer Naßbehandlungsvorrichtung der eingangs genannten Art über den Behandlungstanks trotz eines Abstandes zwischen der Flüssigkeitsoberfläche und einer Abdeckung für die Tanks eine Kondensatbildung und eine vermeidba­re Oxydation der Behandlungsflüssigkeit und den Aus­tritt von Chemikaliengerüchen in den Außenraum zu ver­meiden.The invention is therefore based on the object to prevent condensation and avoidable oxidation of the treatment liquid and the escape of chemical odors into the exterior in a wet treatment device of the type mentioned above the treatment tanks despite a distance between the liquid surface and a cover for the tanks.

Diese Aufgabe wird gelöst durch die Merkmale des Haupt­anspruchs bzw. des Nebenanspruchs 6. Weitere vorteil­hafte Merkmale der Erfindung sind den Unteransprüchen entnehmbar.This object is achieved by the features of the main claim and the secondary claim 6. Further advantageous features of the invention can be found in the subclaims.

Durch die Anordnung eines Deckels oder mehrerer inein­andergreifender Deckelteile, die temperaturisolierend ausgebildet sind, über den Tanks er- und behalten Bäder und Tankwand und Deckelinnenwände eine konstante Tempe­ratur, so daß an den Deckelinnenseiten keine Kondensat­bildung und über den Flüssigkeiten auch keine Wärme- oder Dampfzirkulation entsteht und hierdurch die Oxydation der Bäder wesentlich vermindert wird. Nachdem zusätzlich zu Deckelteilen über den einzelnen Tanks ein sämtliche Tanks überdeckender Isolierdeckel vorgesehen ist oder einzelne Isolierdeckelteile in Falzen oder Nu­ten und Vorsprüngen des umgebenden Gehäuses oder ihrer benachbarten Kanten liegen und die Dampfbildung außer­dem sehr stark vermindert ist, können von den Tankober­flächen auch keine Dämpfe und Gerüche mehr in den Außenraum austreten. Sind dann noch die Durchtritts­schlitze für die Schichtträger in die Außenräume oder benachbarten Behandlungsvorrichtungen (wie benachbarte Tanks oder einen Trockner) durch bekannte Verschluß- , Abstreif- oder Absaugvorrichtungen nach außen gegen Dampf- oder Flüssigkeitsdurchtritt abgedichtet, so ist der Naßteil einer erfindungsgemäßen Naßbehandlungsvor­richtung gegenüber der Umgebung praktisch hermetisch abgeschlossen.Through the arrangement of a lid or several interlocking lid parts, which are designed to be temperature-insulating, the baths and tank wall and lid inner walls maintain and maintain a constant temperature, so that no condensation forms on the inside of the lid and no heat or steam circulation occurs above the liquids and hereby the Oxidation of the baths is significantly reduced. After an insulating cover covering all tanks is provided in addition to cover parts over the individual tanks or individual insulation cover parts lie in folds or grooves and protrusions of the surrounding housing or their adjacent edges and the vapor formation is also greatly reduced, no vapors or odors can occur from the tank surfaces emerge more into the outside space. If the through-slots for the layer supports into the outer spaces or adjacent treatment devices (such as adjacent tanks or a dryer) are then sealed off from the outside against steam or liquid penetration by known sealing, stripping or suction devices, the wet part of a wet treatment device according to the invention is against the environment practically hermetically sealed.

In den Figuren 1 und 2 sind das Gehäuse einer Filment­wicklungsmaschine mit Trockner mit 1, die Tanks für Entwickler, Fixierlösung und Wässerungsbad sowie eine Kammer zwischen Entwickler- und Fixierbad zur Zwischen­wässerung mit 2 bis 5 und zwei Trocknereinheiten bzw. deren Strahler und Gebläse mit 6 und 7 bezeichnet. In den Tanks 2, 4 und 5 befinden sich Racks mit Transport­walzenpaaren, die nur schematisch angegeben und nicht beziffert sind. Vor dem ersten Tank 2 und nach dem letzten Tank 5 sind Gerätewände vorgesehen, in denen Durchtrittsschlitze 8 zum Ein- und Ausführen der zu be­handelnden Schichtträger vorgesehen sind. Auch an den Übergangsstellen von einem Tank zum nächsten können Zwischenwände 9 mit Durchtrittsschlitzen vorgesehen sein. Um ein Austreten von Dämpfen oder Flüssigkeits­tröpfchen durch diese Durchtrittsschlitze für die Schichtträger zu verhindern, können Dichtlappen 10 vor­gesehen sein, die beim Durchführen eines Schichtträgers in dessen Transportrichtung hochklappen, dabei aber an ihm anliegen. Statt dessen können in bekannter Weise an den Durchtrittsschlitzen aber auch bekannte Absaugge­bläse für die über den Tanks entstehenden Dämpfe oder bei an einem Tankausgang vorgesehenen Durchtritts­schlitzen bekannte Abquetschwalzen vorgesehen sein.In Figures 1 and 2, the housing of a film processor with dryer with 1, the tanks for developer, fixing solution and washing bath and a chamber between developer and fixing bath for intermediate washing with 2 to 5 and two dryer units or their emitters and blowers with 6 and 7 designated. Tanks 2, 4 and 5 contain racks with pairs of transport rollers that are only shown schematically and are not numbered. Device walls are provided in front of the first tank 2 and after the last tank 5, in which through-slots 8 are provided for inserting and removing the substrates to be treated. Partitions 9 with through-slots can also be provided at the transition points from one tank to the next. In order to prevent vapors or liquid droplets from escaping through these through-slots for the layer supports, sealing tabs 10 can be provided which fold up in the transport direction when a layer support is being carried through, but which bear against it. Instead, known suction fans for the vapors arising above the tanks or known squeeze rollers in the case of passage slots provided at a tank outlet can also be provided in a known manner on the passage slots.

Es geht nun aber darum, über den Tanks 2, 4 und 5 und in beschränkterem Maße auch über der Zwischenwässe­rungskammer 3 eine ständige Luftzufuhr und dadurch eine beschleunigte Oxydation der Behandlungslösungen einer­seits und andererseits eine Dampf- und/oder Kondensat­bildung zu vermeiden, die in den Außenraum des Gerä­tes 1, also in dessen Aufstellraum entweichen bzw. durch ihre Zirkulation (Abtropfen der Kondensattropfen, Austausch der Dämpfe mit der Außenluft, erneute Dampf­bildung) eine Erhöhung der Oxydation der Behandlungslö­sungen verursachen. Da, wo es möglich war, sind bereits Abdeckungen für die Behandlungslösungen verwendet wor­den, die teilweise in die Behandlungslösungen eintau­chen, womit in dem eintauchenden Bereich eine Dampf- oder Kondensatbildung verhindert war, nicht je­doch in den Nachbarbereichen der Abdeckungen. In die Behandlungslösungen eintauchende Abdeckungen sind je­doch bei großen Entwicklungsgeräten mit Tanks nicht möglich, weil die Schichtträger über dem Flüssigkeits­niveau in die Tanks ein- und aus ihnen herausgeführt werden müssen, die Abdeckungen also über den Tanks lie­gen und nicht in diese eintauchen dürfen. Die bisher bekannten Abdeckungen für Tanks hatten etwa die Tempe­ratur des Außenraums, während die Behandlungsbäder häu­fig wärmer sind. Es bestand also ein Temperaturgefälle zwischen den Behandlungsbereichen im Geräteinnern und dem Außenraum, der die Dampf- und Kondensatbildung un­ter den nicht wärmeisolierenden, bekannten Abdeckungen bzw. an deren Innenseiten begünstigt hat. Außerdem rei­chen diese bekannten Abdeckungen nicht über die gesam­ten Tanks, so daß bisher immer Dämpfe und damit Gerüche in den Außenraum gelangt sind. Diese unerwünschten Ne­benerscheinungen werden nun durch die folgenden Ausfüh­rungsbeispiele beseitigt. Gemäß den Figuren 1 bis 3 sind über den Tanks je Tank 2 bis 5 ein diesen voll nach außen abdeckendes Abdeck­teil 11 vorgesehen, das seinerseits auf Gehäuse- oder Rückwand oder Zwischenwand zwischen den Tanks aufgelegt ist. Dieses braucht nicht wärmeisolierend zu sein, kann aber trotzdem z.B. als Hohlkörper (ähnlich der Ausbil­dung nach Figur 4) ausgebildet sein. Die Ausbildung als Luft enthaltender Hohlkörper ist dadurch leicht mög­lich, daß ein Kunststoff-Formteil 11a mit einer ebenen Oberkante mit einem flachen Deckel 11b verschweißt oder verklebt wird. Diese Ausgestaltung als Luft enthalten­der Hohlkörper ist, wie gesagt, nach den Figuren 1 und 2 nicht erforderlich, kann aber zu einer zusätzlichen Wärmeisolierung führen. Statt dessen könnte auch wärme­isolierendes Material verwendet werden oder es könnte in die Hohlräume Isoliermaterial, z.B. Styropor, einge­bracht sein. Die Abdeckteile 11 liegen nebeneinander, verhindern also einen Austritt von Dämpfen nicht völ­lig. Deshalb ist die zu Reinigungszwecken zugängliche, gesamte Oberfläche des Naßbehandlungsbereiches zusätz­lich zu den Abdeckteilen 11 noch mit einem wärmeisolie­renden Deckel 12 abgedeckt. Die Deckelränder weisen da­bei Falze oder Stufen 12a auf, die in komplementär aus­gebildete Falze oder Stufen 1a der zu öffnenden Geräte­oberseiten passen. Somit schließt der Deckel 12 den Naßbereich des Geräteinnern hermetisch gegen Tempera­tureinflüsse und Luft von außen, aber auch den Außen­raum gegen Austritt von Dämpfen und Gerüchen aus dem Geräteinnern ab. Hierdurch werden nicht nur die Oxyda­tion der Behandlungsbäder ganz erheblich reduziert, sondern auch die Bildung von Dämpfen über den Tanks 2 bis 5 ganz erheblich vermindert und eine Kondensatbil­ dung an den Innenseiten der Abdeckteile 11 verhindert. Ein Gerät gemäß den Figuren 1 bis 3 kann z.B. als Rönt­genfilmentwicklungsgerät, das mit einem Kassetten­ent- und -beladegerät zusammengebaut ist, bedenkenlos in einem Tageslicht-Röntgenbehandlungsraum aufgestellt werden.But now it is a matter of a constant air supply over the tanks 2, 4 and 5 and, to a limited extent, also about the intermediate washing chamber 3, and thereby one Accelerated oxidation of the treatment solutions, on the one hand, and on the other hand to avoid the formation of steam and / or condensate, which escape into the outside of the device 1, that is to say in its installation space, or through its circulation (dripping of the condensate drops, exchange of the vapors with the outside air, renewed steam formation) cause an increase in the oxidation of the treatment solutions. Wherever possible, covers have already been used for the treatment solutions, some of which are immersed in the treatment solutions, thereby preventing the formation of steam or condensate in the immersed area, but not in the adjacent areas of the covers. Covers immersed in the treatment solutions are, however, not possible with large development devices with tanks because the layer supports have to be introduced into and out of the tanks above the liquid level, i.e. the covers are above the tanks and must not be immersed in them. The previously known covers for tanks had about the temperature of the outside, while the treatment baths are often warmer. There was therefore a temperature gradient between the treatment areas inside the device and the outside, which favored the formation of steam and condensate under the non-heat-insulating, known covers or on the inside thereof. In addition, these known covers do not extend across the entire tanks, so that vapors and thus smells have always been released into the exterior. These undesirable side effects are now eliminated by the following exemplary embodiments. According to FIGS. 1 to 3, a cover part 11, which completely covers the outside, is provided above the tanks for each tank 2 to 5, which in turn is placed on the housing or rear wall or intermediate wall between the tanks. This need not be heat-insulating, but can nevertheless be designed, for example, as a hollow body (similar to the design according to FIG. 4). It can easily be designed as a hollow body containing air by welding or gluing a plastic molded part 11a with a flat upper edge to a flat cover 11b. This configuration as a hollow body containing air, as mentioned, is not necessary according to FIGS. 1 and 2, but can lead to additional thermal insulation. Instead, heat-insulating material could also be used or insulating material, for example polystyrene, could be introduced into the cavities. The cover parts 11 lie side by side, so do not completely prevent the escape of vapors. Therefore, the entire surface of the wet treatment area accessible for cleaning purposes is covered with a heat-insulating cover 12 in addition to the cover parts 11. The lid edges have folds or steps 12a which fit into complementarily shaped folds or steps 1a of the top sides of the device to be opened. Thus, the cover 12 hermetically closes the wet area of the inside of the device against the effects of temperature and air from outside, but also the outside area against the escape of vapors and odors from inside the device. This not only significantly reduces the oxidation of the treatment baths, but also significantly reduces the formation of vapors above tanks 2 to 5 and a condensate balance tion on the inside of the cover parts 11 prevented. A device according to FIGS. 1 to 3 can, for example, be installed as an X-ray film developing device, which is assembled with a cassette unloading and loading device, in a daylight X-ray treatment room without hesitation.

Ebenso, wie dies schon als nicht notwendige Möglichkeit für die Abdeckteile 11 beschrieben worden ist, kann der notwendigerweise wärmeisolierend ausgebildete Deckel 12 aus Isoliermaterial, z.B. Styropor, bestehen. Besser ist es aber, wenn er aus glattem, leicht zu reinigendem Kunststoff geformt und dabei wenigstens zweiteilig aus­gebildet ist. So kann er gemäß Figur 3 aus einer Wan­ne 12b bestehen, auf die eine flache Platte 12c aufge­klebt oder aufgeschweißt ist, so daß der Deckel 12 einen wärmeisolierenden Hohlraum einschließt. In diesen kann vor dem Verbinden der Teile 12b und 12c eine Plat­te 13 aus Isoliermaterial, z.B. Styropor, eingelegt sein. Statt dessen können in den Hohlraum auch Styro­por-Flocken oder dergl. eingeschlossen werden. Natür­lich ist es statt dessen auch möglich, ein Hohlprofil, wie es in Figur 3 sichtbar ist, zu formen und in der Deckelgröße entsprechende Stücke zu zerschneiden und auf die Stirnseiten entsprechend geformte Platten auf­zukleben oder aufzuschweißen.Just as has already been described as an unnecessary option for the cover parts 11, the cover 12, which is necessarily heat-insulating, can be made of insulating material, e.g. Styrofoam. However, it is better if it is formed from smooth, easy-to-clean plastic and is at least formed in two parts. According to FIG. 3, it can consist of a trough 12b onto which a flat plate 12c is glued or welded, so that the cover 12 encloses a heat-insulating cavity. Before connecting the parts 12b and 12c, a plate 13 made of insulating material, e.g. Styrofoam. Instead, polystyrene flakes or the like can also be enclosed in the cavity. Of course, instead of this it is also possible to form a hollow profile, as can be seen in FIG. 3, to cut corresponding pieces in the size of the cover and to glue or weld on appropriately shaped plates on the end faces.

Ein anderes Ausführungsbeispiel, bei dem ein zusätzli­cher, großer, über die offene Geräteoberseite reichen­der Isolierdeckel 12 vermieden werden kann, ist in Fi­gur 4 gezeigt. Hier sind die einzelnen Deckelteile 11 für die einzelnen Tanks 2 bis 5 als Isolierdeckel, z.B. als Hohlkörperteile, ausgebildet. Damit zwischen den einzelnen Deckelteilen 11 jedoch keine Luft in den Tankbereich und keine Dämpfe nach außen dringen können, weisen die Deckelteile 11 profilierte Ränder 11c, 11d auf, die in komplementär geformte Falze 1a der benach­barten Gehäuseränder bzw. komplementär geformte Rand­teile 11e der jeweils benachbarten Deckelteile 11 pas­sen und labyrinthartige Verschneidungen zwischen Gehäu­se 1 und Deckelteilen 11 bilden. In den Verschneidungen 1a, 11c bzw. 11d, 11e könnten noch Dichtungsstreifen, z.B. aus Gummi oder Schaumstoff, angeordnet sein. Diese Ausgestaltung ist zwar teilesparender und erfordert nicht das Hantieren mit einem großen Deckel 12, hat aber den Nachteil, daß die einzelnen Deckelteile 11 in einer bestimmten Reihenfolge auf das Gerät 1 aufgesetzt bzw. von ihm abgenommen werden müssen, damit jeweils die Stufen 11c in die Stufen 1a und die Falze 11e in die Falze 11d passen.Another embodiment in which an additional, large insulating cover 12 reaching over the open top of the device can be avoided is shown in FIG. Here are the individual lid parts 11 for the individual tanks 2 to 5 as an insulating lid, for example as hollow body parts. So that no air can penetrate into the tank area and no vapors can escape between the individual lid parts 11, the lid parts 11 have profiled edges 11c, 11d, which form complementarily shaped folds 1a of the neighboring housing edges or complementarily shaped edge parts 11e of the respectively adjacent lid parts 11 fit and form labyrinthine intersections between housing 1 and cover parts 11. Sealing strips, for example made of rubber or foam, could also be arranged in the intersections 1a, 11c and 11d, 11e. Although this configuration saves parts and does not require handling of a large cover 12, it has the disadvantage that the individual cover parts 11 have to be placed on the device 1 in a certain order or removed from it, so that each of the stages 11c into the Steps 1a and fold 11e fit in fold 11d.
