Definitions

  • the invention relates to a transport device with the features of the preamble of claim 1.
  • transport devices are known for example from DE-A-31 27 016. They are used by photo amateurs as well as in the professional photo sector and are used for the development, washing and fixing of exposed photo paper.
  • the transport of the paper is usually carried out by pairs of transport rollers, the photo paper running under frictional engagement through the passage gap between two mutually interacting transport rollers. At least one of the two rollers is driven and the passage gap for the photographic layers is designed to be slightly flexible. The flexibility of the passage gap is particularly important for the development process because the development process can be adversely affected by excessive pressure on the photosensitive layer.
  • the belt-like or sheet-like photographic layer supports are transported through the photochemical baths with the aid of a conveyor roller, in which disk-shaped or similarly shaped transport elements are arranged on a roller core.
  • These transport elements are designed to be flexible in the radial direction. The flexibility is achieved there, however, in that the elements arranged continuously on the core or else the elements arranged at a distance from one another consist of an elastic material, such as foam rubber, rubber, or the like, or are designed in the form of brushes.
  • Pressure rollers of this type can, however, be disadvantageous since foam-like, in particular porous material can undesirably store oxidation products of the developer.
  • the invention has for its object to provide a transport device for carrying out tape or sheet-shaped photographic supports through photochemical baths of developing machines, which is simple and inexpensive to manufacture and maintain and which ensures high quality of the development products even over longer periods of time.
  • the pressure elements are designed as elastic radially deformable hat slats, the axis of symmetry of which is parallel to the roller axis and which have the shape of hemispherical shells or conical shells which are open on one side and whose open side is approximately at right angles to the shaft core .
  • the invention provides a transport device which treats the paper extremely gently, with the individual, radially flexible pressure elements ensuring a constant contact pressure for the entire roll length.
  • Each of the elements acts as an isolated, circular, spring element axially decoupled from the other, so that any non-roundness in the roller run may not have a significant effect on the contact pressure that is exerted on the paper.
  • the spring action is not limited to a defined spring direction, as is the case, for example, with hard rollers mounted in elongated holes, but the outer surfaces of the elements interacting with the paper can gently nestle against the paper surface and any existing paper curvatures without the paper is subjected to a hard linear load between the rollers.
  • the hat slats be fastened to the shaft core with the wall section axially opposite the open side (claim 2).
  • the hat slats can be formed in one piece with a bearing sleeve which is arranged on the shaft core with an adhesive seat and which projects axially beyond the open side.
  • the wall angle of the conically shaped hat slats should be about 45 °. It is advantageous if the hollow bodies of the hat slats are made of polyethylene.
  • two adjacent hat slats should be parallel with each other with their open sides.
  • the device is characterized in that one or more sections of the hollow body cross section is designed as an elastically resilient bellows.
  • the inside of the transport device for carrying out band-shaped or sheet-shaped photographic layer supports has a plurality of parallel transport rollers, with three rollers lying next to one another at the same time in the so-called “roller centers” 1-4, and the roller facing the uncoated rear side of the layer support being designed as a lamella roller 5 is.
  • This is provided with a plurality of resilient lamellar disks 7 which protrude radially from the roller axis 6 and whose peripheral surfaces protrude or touch the surfaces 8 of the outer rollers 9, 10.
  • the passage gaps 11 for the photographic layer supports lie between the lamella roller 5 and the outer rollers 9, 10.
  • the outer rollers 9, 10 are mounted with a rigid mutual spacing 37 in the rack side parts 12, 13.
  • the lamellar roller 5 has a shaft core 14 and the lamellar disks 7 are designed as flat perforated disks which are attached to the core 14 and which are fixed on the shaft core 14 by spacer disks 15 of smaller diameter lying between them.
  • the ends 16, 17 of the shaft core 14 are rotatably supported in bearings 18, 19 of the rack side parts 12, 13.
  • the central reversing roller located in the lower feed-through U-arch 20 of the rack is also designed as a lamellar roller 21 which is surrounded by a plurality of rigidly arranged U-shaped guide rollers 22.
  • the guide rollers 22 are also provided with fins, which need not be radially flexible.
  • the axial offset of the lamellae from the adjacent guide rollers 22 enables the lamellae to be immersed in the spaces between the lamellae, so that a paper jam can be avoided.
  • a plurality of guide elements 23 designed as elongated rods which penetrate the lamellar rollers within the roller diameter 24 of the lamellar roller 5.
  • a guide element designed as a U-shaped bracket passes through a plurality of rollers lying one above the other trios, the free U-legs 25 form the guide rods and the guide elements in the area of their U-head 26 are fastened to a holding rod 27 which passes through the rack parallel to the rollers.
  • All guide rollers of the rack are driven.
  • the drive takes place within a roller trio, i. H. between the two outer rollers and the middle roller by pinions, which are located on the outside of a rack side part (e.g. 12).
  • the roller trios are driven by toothed or chain drives, which are arranged on the outside of the other rack side part (e.g. 13) for reasons of balance.
  • the guide rollers are driven by planet gears, which are driven by a sun gear arranged on the shaft of the lower lamella roller 21, which acts as a deflection roller.
  • the drive gears / chain drives are not shown in the drawing figures.
  • the plane of the roll trios 1-4 is inclined with respect to the main directions 28, 28 'so that the outer rolls are offset in the direction of flow with respect to the middle roll, so that the front paper edge, the roll trio, is slightly bent towards the guide element 23 in the direction of arrow 29 as it exits the passage gap .
  • the upper part 30 of the rack lying above the liquid level 31 can be removed from the lower part 32 by means of a parting line 33 which runs approximately horizontally between the uppermost roll trio 34 and further guide rollers.
  • Lamellar rollers 35, 35a similar to the rollers 5, and a smooth roller 35b, similar to the rollers 9, 10, are arranged on the upper side of the rack 30 for guiding or conveying the paper.
  • Conveyor or guide rollers 39 and 39a are located on the outlet side of the rack upper part.
  • a bolt 36 which is only sketched, ensures that the upper part and lower part are exactly adjusted to one another in the operating position.
  • hat slats 50 are pushed onto a shaft core shown in sections in such a way that two are each directed with their open sides 51 towards one another and so to speak form a pair of hat slats.
  • the open sides 51 run at right angles to the roller axis 6.
  • the hat slats 50 are provided in their peripheral region with a first substantially cylindrical section 52, the outer side 53 of which forms the contact surface with the photographic paper.
  • This cylindrical section 52 is followed by a conical wall part 54, which encloses an angle 55 of approximately 45 ° with the roller axis 6.
  • the wall part 54 merges in one piece into a bearing sleeve 56, which protrudes somewhat beyond the open side 51, so that the lower edges of the outer sides 53 of two cones lying against one another with their open sides 51 have a deflection distance 57.
  • the deflection movement of the edges of the hat slats 50 under radial pressure is indicated by the arrows 58.
  • FIG. 5 Another arrangement of the hat slats relative to one another is shown in FIG. 5. With their open sides 51 they do not point towards each other, but in the same direction. However, with such an arrangement, care must be taken that, for example, the hat slats of the other shaft end point in the opposite direction.
  • the hat slats shown in FIG. 5 are provided with bellows 59 arranged in the wall part 54.
