(54) Filmfremkaldels es apparat.(54) Film development apparatus.
Den foreliggende opfindelse angår et filmfremkaldelsesappa-rat omfattende en fremkaldelsessektion bestående af et antal væskebade og tilhørende valsesæt hvert bestående af to ovenover hinanden placerede valser til successivt at føre filmstrimler gennem disse bade, og en med filmfremføringsorganer forsynet tørresektion, hvorhos den ene valse i et valsesæt er elastisk og anbragt løst lejret i lejringsspor, jjj som muliggør en bevægelse af valsen i lodret retning til kontakt med jq den anden valse.The present invention relates to a film development apparatus comprising a development section consisting of a plurality of liquid baths and associated roll sets each consisting of two superposed rollers for successively passing film strips through these baths, and a drying section provided with film feeding means, the one roll of a roll set. is elastic and loosely mounted in bearing grooves, which enables a movement of the roller in a vertical direction to contact the jq of the second roller.
^ For at kunne opnå en optimal udnyttelse af et sådant film- _ø fremkaldelsesapparat kræves det, at det skal kunne anvendes til fremly kaldelse af både meget brede filmstrimler, f.eks. med en bredde på op til 1,2 m, og af et antal smallere filmstrimler, der fremføres samti-^ digt og i parallelle baner gennem apparatet.^ In order to achieve optimum utilization of such a film-making apparatus, it is required that it be utilized to produce both very wide film strips, e.g. with a width of up to 1.2 m, and of a number of narrower film strips conveyed simultaneously and in parallel paths through the apparatus.
2 1458082 145808
Forudsætningen herfor er, at de valsesæt, hvorigennem filmstrimlen eller -strimlerne passerer, over hele valsesættenes længde udøver et ensartet tryk på filmstrimlerne. I modsat fald vil en bred filmstrimmel blive ført skævt gennem apparatet, og i tilfælde af samtidig fremkaldelse af et antal relativt smalle filmstrimler vil disse ikke blive transporteret gennem apparatet på ensartet måde.The prerequisite for this is that the roll sets through which the film strip or strips pass over the entire length of the roll sets exert uniform pressure on the film strips. Otherwise, a wide film strip will be skewed through the apparatus, and in the case of simultaneous development of a number of relatively narrow film strips, these will not be transported through the apparatus in a uniform manner.
Der kendes et apparat til fremkaldelse eller fiksering af fotografiske materialer, og i hvilket materialet befugtes på begge sider med et tyndt væskelag ved hjælp af to roterbare fugtevalser. I et sådant kendt apparat er den øverste af to sådanne samvirkende fugtevalser løst lejret i et lejringsspor over den anden fugtevalse og består af et elastisk deformerbart materiale, f.eks. i form af et kautsjukrør med en fyldning af et flydende stof eller af faste legemer.An apparatus for developing or fixing photographic materials is known and in which the material is wetted on both sides with a thin liquid layer by means of two rotatable moisture rollers. In such a known apparatus, the top of two such cooperating moisture rollers is loosely mounted in a bearing groove over the second moisture roll and consists of an elastically deformable material, e.g. in the form of a rubber tube with a filling of a liquid substance or of solid bodies.
Formålet med den foreliggende opfindelse er at tilvejebringe et apparat af den i indledningen nævnte art, hvor der på simpel måde kan tilvejebringes et ensartet justerbart valsetryk over valsesættets fulde længde.The object of the present invention is to provide an apparatus of the kind mentioned in the preamble, in which a uniformly adjustable roll pressure can be provided over the full length of the roll set in a simple manner.
Dette formål opnås med apparatet ifølge den foreliggende opfindelse, hvilket apparat er ejendommeligt ved, at den nedre valse, som er helt eller delvis neddykket i væske, er løst lejret i lejringssporet og fremstillet af et sådant materiale, at valsens vægtfylde er mindre end vægtfylden af væsken, hvori den er neddykket.This object is achieved with the apparatus of the present invention, which is characterized in that the lower roller, which is wholly or partially submerged in liquid, is loosely stored in the bearing groove and made of such material that the weight of the roller is less than the weight of the roller. the liquid in which it is immersed.
Som følge af den løse lejring af den nedre valse og dennes relativt ringe vægtfylde vil den nedre valse af opdriftskræfterne blive presset op mod den øvre valse, når der indføres væske i den pågældende del af apparatet.As a result of the loose bearing of the lower roller and its relatively low density, the lower roller of the buoyancy forces will be pressed up against the upper roller as fluid is introduced into that part of the apparatus.
Den nedre valse er fortrinsvis fleksibel, og den del af valseoverfladen, som er i kontakt med den øvre valse, vil i så fald tilpasse sig den øvre valses overfladekontur. Dette medfører, at de to valser vil være i indbyrdes kontakt over stort set hele valsesættets længde, selv når relativt smalle filmstrimler i parallelle baner transporteres gennem apparatet. Størrelsen af trykket, hvormed den nedre valse påvirker den øvre valse, vil ved en simpel ændring af væskestanden i badet kunne indstilles efter ønske.Preferably, the lower roller is flexible and the portion of the roller surface in contact with the upper roller will adapt to the surface contour of the upper roller. This means that the two rollers will be in contact with each other over virtually the entire length of the roll set, even when relatively narrow film strips in parallel webs are transported through the apparatus. The magnitude of the pressure by which the lower roller affects the upper roller can be adjusted by a simple change in the liquid level in the bath.
Den nedre valse består fortrinsvis af polyurethanskum med en 3 vægtfylde på ca. 0,4 g/em . Herved opnås en i de normale anvendte fremkaldervæsker passende opdrift.The lower roller preferably consists of polyurethane foam having a density of approx. 0.4 g / cm Hereby a buoyant fluid used in the normal developing liquids is obtained.
Andre skumstoffer end polyurethanskum kan også anvendes, og det er ligeledes muligt som nedre valse at anvende et fleksibelt, ved begge ender tæt tillukket hult rør.Foam materials other than polyurethane foam can also be used, and it is also possible to use as a flexible roller a flexible hollow tube at both ends, closed.
3 145808 Når den nedre valse er fremstillet af polyurethanskum, sker fremstillingen af valsen hensigtsmæssigt i en rørform. Under op-skumningen af den opskummelige blanding dannes der i området op til rørvæggen en sammenhængende væskeuigennemtrængelig hinde eller skal, der bibringer den dannede valse en glat og ensartet overflade, som forhindrer en indtrængning af væske i selve skummaterialet.When the lower roller is made of polyurethane foam, the roll is conveniently made in a tubular form. During the foaming of the foamable mixture, a continuous liquid or impermeable membrane or shell is formed in the region up to the tube wall which imparts a smooth and uniform surface to the formed roller which prevents the ingress of liquid into the foam material itself.
En af polyurethanskum fremstillet valse frembyder den yderligere fordel, at den er modstandsdygtig mod kemisk angreb af fremkaldervæsker.A polyurethane foam roller provides the additional advantage of being resistant to chemical attack of developer fluids.
Opfindelsen skal herefter beskrives nærmere under henvisning til tegningen, hvor:The invention will now be described in more detail with reference to the drawing, in which:
Pig. 1 viser et skematisk billede af et filmfremkaldelsesapparat ifølge opfindelsen, og fig. 2 viser et lodret snit gennem de to første væskebade i fremkaldersektionen i det i fig. 1 viste apparat.Pig. 1 is a schematic view of a film developing apparatus according to the invention; and FIG. 2 shows a vertical section through the first two liquid baths in the developer section of the FIG. 1.
Det i fig. 1 viste fremkaldelsesapparat omfatter en fremkaldelsessektion 1 og en tørresektion 2. Oven på fremkaldelsessektionen 1 er der under en hætte 3, der har en bakkeformet forsænkning til opfangning af fremkaldte film, anbragt en motor 25, der er indrettet til at trække såvel fremkaldelsessektionens som tørresektionens valser.The FIG. 1 develops a developing section 1 and a drying section 2. On top of the developing section 1, under a hood 3 having a tray-shaped recess for catching developed films, a motor 25 adapted to pull the rollers of the developing section and the drying section is arranged. .
Den del af fremkaldelsessektionen 1, som er vist mere detailleret i fig. 2, omfatter en underdel 5, som har et antal væskerum, hvoraf der er vist to, 6, 7. Disse to væskerum er adskilte ved hjælp af en skillevæg 8.The part of the developing section 1, which is shown in more detail in FIG. 2, comprises a lower part 5 having a plurality of fluid compartments of which two, 6, 7. are shown. These two fluid compartments are separated by a partition 8.
I væskerummet 6, hvis bund i det midterste område har form som en krum ledeflade 9, er der anbragt to valsesæt 10, 11 og 12, 13. Valsen 12, der ved enderne er lejret i væskerummets 6 sidevægge, har ved den ene ende et tandhjul 14, der er i indgreb med et snekkedrav 15 på en vandret liggende aksel 16, der drives af den i fig. 1 viste motor 25. Valsen 10 og en valse 17 i et i væskerummet 7 anbragt valsesæt 17, 18 drives på tilsvarende måde ved hjælp af akselen 16. Valserne 11, 13 og 18 har ved enderne akseltappe, som er løst lejrede i spor 19, som er udformet i endevæggene i væskerummene 6, 7. Valserne 11, 13 og 18 er bøjelige og er fremstillet af f.eks. polyurethanskum og har en vægtfylde, som er mindre end vægtfylden af væskerne i væskerummene 6, 7. Som følge heraf vil valserne 11, 13 og 18 med en væskestand som den i fig. 2 viste under indvirkning af opdriften blive pressede mod valserne 10, 12, henholdsvis 17, idet der opnås et ensartet tryk mellem to samvirkende valser på hele disses kontaktflade. Over væskerum- t 4 145808 mene er der anbragt et låg 20, som i området over skillevæggen 8 har en nedadvendende krum flade 21, der tjener som filmledeflade. Mellem låget 20 og underdelen 5 er der tilvejebragt en indføringsspalte 22, hvorigennem filmene, der skal fremkaldes, indføres i apparatet. Filmene ledes ved hjælp af en skråflade 23 på undersiden af låget 20 ind i spalten i valsesættet 10, 11 og føres ved hjælp af dette ned i væsken i væskerummet 6. Ved hjælp af ledefladen føres den i væskerummet 6 indførte film ind i spalten i valsesættet 12, 13 og videre i kontakt med ledefladen 19 ind i spalten i valsesættet 17, 18. Herefter passerer filmen ind i væsken i det andet væskerum 7 og passerer gennem dette på tilsvarende måde som beskrevet i forbindelse med passagen gennem væskerummet 6. Fremføringen af filmen gennem de yderligere væskebade kan ske på samme måde som beskrevet ovenfor.In the fluid compartment 6, whose bottom in the middle region has the shape of a curved guide surface 9, two roller sets 10, 11 and 12, 13. The roller 12, which is mounted at the ends in the side walls of the liquid compartment 6, has a gear 14 engaging a worm gear 15 on a horizontal shaft 16 driven by the FIG. 1, the roller 25 and a roller 17 in a roller set 17, 18 arranged in the fluid chamber 7 are similarly driven by the shaft 16. The rollers 11, 13 and 18 have at their ends shaft pins loosely mounted in groove 19, formed in the end walls of the liquid compartments 6, 7. The rollers 11, 13 and 18 are flexible and are made of e.g. polyurethane foam and has a density less than the density of the liquids in the liquid compartments 6, 7. As a result, the rollers 11, 13 and 18 will have a liquid level similar to that of FIG. 2 are pressed against the rollers 10 against the rollers 10, 12 and 17 respectively, obtaining a uniform pressure between two cooperating rollers on the entire contact surface thereof. A lid 20 is provided above the liquid space 4 14580, which in the area above the partition wall 8 has a downwardly curving surface 21 which serves as a film guide surface. An insertion slot 22 is provided between the lid 20 and the bottom part 5 through which the films to be developed are introduced into the apparatus. The films are guided by means of an inclined surface 23 on the underside of the lid 20 into the slot in the roller set 10, 11 and by this are introduced into the liquid in the liquid space 6. By means of the guide surface, the film introduced into the liquid space 6 is introduced into the slot in the roller set. 12, 13 and further, in contact with the guide surface 19 into the slot in the roller set 17, 18. Thereafter, the film passes into the liquid in the second liquid compartment 7 and passes through it in a similar manner as described in connection with the passage through the liquid compartment 6. The conveying of the film through the additional liquid baths can be done in the same manner as described above.
Fra fremkaldelsessektionen passerer den fremkaldte og skyllede film derpå ind i tørresektionen, og efter at have passeret op gennem denne kommer filmen ud gennem en spalte, som udmunder i den bakke-formede forsænkning 4. I fig. 2 er der yderligere vist et i sidevæggen i væskerummet 6 indsat rør 24. Dette rør tjener til væskestandsrør og til at udtømme væsken fra væskerummet 6. Tilsvarende organer kan være tilvejebragt i de øvrige væskerum.From the developing section, the developed and rinsed film then passes into the drying section, and after passing through it, the film emerges through a slit which opens into the tray-shaped recess 4. In FIG. 2, there is further shown a tube 24. Inserted into the side wall of the fluid compartment 6 This tube serves for fluid level pipes and for discharging the liquid from the liquid compartment 6. Corresponding means may be provided in the other fluid compartments.
