Definitions
- the invention relates to a device for developing sheet-like or band-shaped photographic material according to the generic term of the independent Claim.
- a device of this kind is disclosed by EP-0 222 583-A.
- Devices for developing slatted or ribbon-shaped photographic material are well known in the field of photofinishing, in the case of films to be developed as film processors and in the case of exposed paper as Paper processors.
- the paper exposed in the printer and to be developed in the paper processor either as Single sheet is available or in the form of long paper tapes that only after the Development can be cut into individual paper images.
- the single sheets or Paper tapes are used for development through one or more wet chemical baths transported, the development of the Pictures done.
- the volume of such wet chemical baths in the processors - in the following the For the sake of simplicity only paper processors discussed - depends essentially on what throughput (number of images developed per unit of time) the respective user, usually development laboratories. For a higher throughput, the The length through the paper processor must be correspondingly long so that as many pictures as possible can be in the paper processor at the same time and with continuous transport on the one hand and relatively fast transport speed on the other hand the Lead time of the paper through the paper processor of the necessary for the development Duration corresponds (this is predetermined). This has relatively large volume bathrooms Episode.
- minilabs For users of so-called minilabs or microlabs (both are described below referred to as minilabs), however, a significantly lower throughput is of interest. As a result, the transport speed through the wet chemical baths can also be reduced. Therefore, the bathrooms of such minilabs are only considerably smaller Volumes required. However, it is also necessary for the baths of such minilabs that the developing liquid is always "fresh" so that the developed paper images all meet a uniform quality standard. As a result, the low-volume bathrooms need to be renewed or supplemented from time to time. Furthermore a lively movement of the wet chemical baths in the paper processor has proven to be advantageous proven, because in this way fresh developing liquid always comes into contact with comes to the paper to be developed.
- the developing liquid in the paper processor expires after a certain time but also unusable (the developing liquid oxidizes) when it is practically not is needed (if no development orders are processed); then it must be completely replaced.
- the development fluid must be replenished or regenerated so that it remains stable and does not become unusable. This requires per unit area developed a predetermined amount of regenerate or fresh paper Developing liquid are fed to the bath. The lower the total in the The volume of developing liquid in the paper processor is the faster practically everything in the paper processor even with low throughput Volume of developing liquid regenerated or exchanged. Paper processors that provide a small volume of developing liquid in relation to the throughput, therefore have a higher long-term stability.
- Paper processors with a high long-term stability are especially advantageous for those already addressed mini and microlabs, where the average throughput is relative is small, but still a powerful device is needed to control the To cope with peak loads (e.g. in one-hour service).
- peak loads e.g. in one-hour service.
- a mini or microlab must on the one hand have the route through the paper processor be long enough to cope with the peak loads, on the other hand it has to total volume of development fluid should be as small as possible, so low average throughput high long-term stability is guaranteed.
- the Paper processors from time to time also the transport rollers (and if necessary also other elements of the paper processor) are cleaned so that it is not due from contamination of elements of the paper processor to loss of quality in the developed paper pictures comes.
- To clean either the rollers from the Paper processor removed or they must be cleaned inside the paper processor are - however, they are usually removed for cleaning.
- the paper processor it is therefore desirable and an object of the invention that this Cleaning can be done easily and quickly.
- the processor should also easy to manufacture and yet reliable in function.
- the device comprises two together connectable half-shells, in the wall of which bulges are provided. Furthermore
- the device comprises two elements, approximately having the shape of a ladder, on which first transport rollers are provided. These first transport rollers are on the respective ladder-shaped element arranged so that when the ladder-shaped elements in the connected half-shells in the bulges of the wall fit into the respective half shell.
- the device further comprises a central one Element that after inserting the two ladder-shaped elements between the two ladder-shaped elements can be introduced.
- this central element After inserting the central element stops this central element - often called "rack" - the two ladder-shaped elements in their Position and defined together with the respective ladder-shaped element or together with the wall of the respective half-shell the channel for the one to be developed photographic material.
- This channel extends between the respective ladder-shaped Element and the central element or between the wall of the respective half-shell and the central element and has a reversal point at the bottom.
- To the The central element is provided with two transport rollers which are connected to the first Transport rollers of the ladder-shaped elements are in contact, so that the to be developed photographic material between the first transport rollers and the second transport rollers guided and transported through the canal.
- Such a device can disassembled and reassembled easily and quickly and is reliable in its function.
- such a device can be produced in a simple manner.
- Fig. 1 are two empty half-shells of an embodiment of the invention Device to recognize a left half-shell 1 and a right half-shell 2 (left and on the right, as with the explanations below, are only for the respective one Drawing figure related).
- the left half-shell has a wall 10 in which several Bulges 10a, 10b and 10c are provided.
- the wall 20 of the right half-shell bulges 20a, 20b, 20c are also provided.
- At the bottom of each Half-shell 1 and 2 there is an outlet 11 and 21 for Developing liquid.
- the two half-shells become liquid-tight with one another connected, e.g. can be glued or ultrasonically welded, it is important that they are connected to each other in a liquid-tight manner.
- Fig. 2 shows the individual elements that are introduced into the two half-shells to complete the device according to the invention further.
- these elements on the one hand there are the two ladder-shaped elements, the left ladder-shaped Element 3 and the right ladder-shaped element 4, and on the other hand around the central Element 5, the "rack".
- These first transport rollers can be made elastic and / or be resiliently mounted, in principle similar to that shown in US-A-5,270,762 and described (see Fig. 4 there).
- the ladder-shaped elements naturally each have a corresponding second one Side spar, which is however not shown (it is almost above the drawing level).
- the first transport rollers are each continued by shafts 33a, 33b, 33c and 43a, 43b, 43c. By turning these shafts, the first transport rollers are also together with the Rotatable shafts.
- the gears are not visible in Fig. 2, they are quasi arranged behind the roles, i.e. behind the drawing level, but still before the corresponding side rail 30 or 40 (indicated in Fig. 9), that is quasi between the respective first transport roller and the respective side rail 30 or 40.
- each guide piece 31 for provided the photographic material.
- each guide pieces which are designated overall with 32 or 42, and several hook-like fingers 32a and 42a and connecting pieces 32b and 42b have, which are arranged between the hook-like fingers, so that the hook-like fingers 32a and 42a and the connecting pieces 32b and 42b always take turns in turns. This can be seen even better from FIG. 3.
- the central element 5 (FIG. 2), that is to say the rack, has two side flanges, one of which only one side flange 50 is shown (the other is virtually above the drawing plane).
- the guide piece 51a is formed at the upper end as a handle with which Help the rack is inserted into the interconnected half-shells 1 and 2, after the two ladder-shaped elements 3 and 4 have been introduced. Naturally the rack can also be pulled out using the handle.
- guide pieces are also used for Filling volume so that the total volume of developing liquid in the Device can be kept low.
- the guide pieces 51a, 51b, 51c are on the Side flanges 50 attached. In principle, this is similar to US-A-5,331,235 described (see there Fig. 9).
- the second transport rollers 50a, 50b, 50c, 50d, 50e are - like the first transport rollers - continued by waves 53a, 53b, 53c, 53d, 53e. By turning the associated shaft the second transport rollers can be rotated together with the associated shaft.
- On the The shaft 53a, 53b, 53c, 53d, 53e are each provided with (shaft) gearwheels, which cannot be seen in FIG. 2. They are behind the second transport rollers in FIG. 2, that is, arranged behind the drawing plane, but still in front of the side flange 50.
- other gears are shown in dashed lines in Fig.2 and with the Numbers 54a, 54b, 54c, 54d provided ("intermediate gears").
- This (intermediate) Gears 54a, 54b, 54c, 54d are arranged between the (shaft) gears on the respective extension of the shafts 53a, 53b, 53c, 53d, 53e are arranged.

- the guide pieces 51a, 51b, 51c in a distance on the side flange so that both the gears on the Projections of the shafts 53a, 53b, 53c, 53d, 53e, as well as those arranged between them (Intermediate) gears 54a, 54b, 54c, 54d are freely rotatable.
- the (intermediate) gear 54a now engages in the (shaft) gear on the Extension of the shaft 53a, this (shaft) gear in turn engages the gear 54b on.
- the (intermediate) gear 54b in turn engages in the (shaft) gear on the Extension of the shaft 53b, and so on.
- this can be done as follows it can be seen in US-A-5,311,235 and there in Fig. 9 (only that there the gears quasi outside the side flange - at least outside the inner side flange to grab).
- the gear 54a all on central part or rack arranged transport rollers, i.e. the second transport rollers 50a, 50b, 50c, 50d, 50e, driven (via the meshing of the gears).
- the gear on the extension of the shaft 53b also engages in the gear 54c still in the gear on the extension of the shaft 33a.
- the gearwheel also engages on the extension of the shaft 53a also in the gear on the extension of the shaft 43a. This is indicated in Fig. 3.
- the gear on the Extension of the shaft 53c still in the gears on the extension of the shaft 33b and in Gear on the extension of the shaft 43b.
- the gear on the extension of the shaft 53d finally engages in the gear on the extension of the shaft 33c and further in the Gear on the extension of the shaft 53e and in the gear on the extension of the shaft 43c.
- the system would also work if only the transport rollers of the central part 5 would be driven (second transport rollers). With the additional Drive of the transport rollers 30a, 30b, 30c and 40a, 40b, 40c of the two ladder-shaped Elements 3 and 4, however, are more secure.
- the guide pieces 32 and 42 arranged at the lower end of FIG. 2 on the two ladder-shaped elements 3 and 4 have already been mentioned above.
- the Guide pieces 32 and 42 alternately have hook-like fingers 32a and 42a and Connectors 32b and 42b between these hook-like fingers.
- the central Element 5, i.e. the rack has two guide pieces at the lower end, all of them are denoted by 51d and 51e.
- These guide pieces 51d and 51e also have in Alternate guides 51f and 51g and connectors 51h and 51i between them Guides 51f and 51g.
- the guides 51f and 51g are arranged so that when Introducing the central element 5 (rack) the guides 51f and 51g of the Guide pieces 51d and 51e into the spaces between the hook-like fingers 32a or 42a slide in.
- FIG. 3 in which a section is shown, which one Supervision of the guide piece 32 and the associated guide piece 51d corresponds and their spatial arrangement indicates each other.
- the guides 51f not slid into the spaces between the hook-like fingers 32a since the two parts are shown spatially separated from each other. In practice they slide Guides 51f when inserting the central element 5 into the spaces between the hook-like fingers 32a so that the paper is securely guided at all times, first on the curved surface 32c of the guide piece 32 and then on the curved surface 51j of the guide 51f (Fig. 2).
- the tube 57 passes through which fresh or supplemented developing liquid is supplied becomes.
- the tube 57 has openings 57a in its wall through which the fresh or supplemented development liquid first enters the chamber 56 and then through the slot-shaped openings 56a and 56b through the photographic material applied.
- the tube 57 itself can be designed as a filter, which Contamination in the supplied developing liquid retains or it can be separate hollow cylindrical filter 57d around the tube, but not in contact with the Tube 57 may be provided (indicated by dashed lines).
- Fig. 6 shows (greatly enlarged) the already mentioned oriel 12 and the fixed therein arranged hollow cylindrical counterpart 14, in which the hollow cylindrical filter 13 is provided to retain dirt (particles).
- the counterpart 14 is firmly and liquid-tightly connected to the oriel 12.
- a hollow cylindrical space 15 is formed between the counterpart 14 and the filter 13 .
- a nozzle 16 can use a nozzle 16 to supply fresh or supplemented development liquid be fed.
- the pipe fitting 57b inserted in the oriel 12 recognizable (reduced view). The developing liquid comes from the hollow cylindrical space 15 through the filter 13 into the pipe fitting 57b and thus into the tube 57.
- FIGS. 8 and 9 An embodiment of the drive will now be briefly explained with reference to FIGS. 8 and 9 become.
- a Worm gear 60 is provided, which meshes with a gear 540a.
- the gear 540a is also arranged outside the half shells, but on the same shaft on which the Gear 54a is arranged. So this wave protrudes into the interior of that of the two Half shells 1 and 2 is formed.
- the gear 54a which is now all the first and drives second transport rollers (by means of the shaft gearwheels and the intermediate gearwheels, as explained above), namely is arranged in the interior of the device.
- This kind of The drive is advantageous in this respect, since in practice several such shells and half shells elements to be introduced existing devices can be connected in series can, all synchronously by means of the shaft 6 and worm wheels provided thereon can be driven.
- such has a whole and outside the interior of the device arranged drive the advantage that if only one of the devices needs to be cleaned, not the entire drive removed or must be dismantled, as is the case when each device has its own drive has, which is then possibly also arranged inside the respective device.
- FIG. 10 a further embodiment of the Device according to the invention are explained, in which the supply of fresh or supplemented development liquid not through a tube 57 in the central element 5, but through the wall 10 or 20 of the two half-shells 1 and 2.
- Fig. 10 can be seen a view in which the connecting piece 17a and 27a for the Development fluid supply can be seen.
- the respective connection piece 17a or 27a opens into a tube 17 or 27 (FIG. 11) which extends along the wall 10 or 20 extends.
- a slot 18 or 28 FIG.
- this embodiment differs from that previously explained essentially only in that the developing liquid flows through a slot 18 or 28 is supplied in the wall 10 or 20 and not through the slit-shaped Passage openings 56a and 56b of the central element 5 (rack). It is of course, that if necessary along the canal in various other places further such slots can be provided in the wall 10 or 20, such as this is described, for example, in US-A-5,270,762 (see there Fig. 9, Fig. 10).
- the development devices described are specifically for development suitable for exposed photographic paper, especially for sheet-shaped paper, but also of paper tapes. Several such devices can also be used in succession be switched.
- the device is easy to manufacture (plastic technology), can easily and above all can be quickly assembled and disassembled if individual parts - especially the rollers - must be cleaned, and is reliable in function.
- This in the volume of developing liquid present in the device is small. There too the exposed surface of the liquid is small, there is only a slight oxidation instead of. Because of the small total volume of developing liquid, the Maintenance or cleaning even this small volume of development fluid be drained and disposed of. This is both from the aspects of environmental protection as also advantageous from the cost side.
- the development devices described are specifically for use in mini and Microlabs with single sheet processing is suitable because it is used in the field of mini or Microlabs is less about large quantities of standard orders, but rather on them arrives to be able to respond flexibly and quickly to special customer requests.
- the paper size must be changed quickly and when changing the Paper size can be kept low.
- the professional Single sheet processing also plays an important role.
