Definitions

  • the invention relates to a device for developing microfilms, in which the exposed film successively passes through various workstations, such as developer bath, fixing bath pre-watering, post-watering and drying, along a horizontally arranged path with the aid of a motor-driven pair of rollers, with a liquid circulation system, each of which has a workstation is designed as a transport container with a liquid supplying vessel and has a feed pipe and a suction pipe, the suction pipe leading the liquid via a liquid pump via pressure pipes to a bath of the assigned work station and there against the horizontally running underside of the film.
  • workstations such as developer bath, fixing bath pre-watering, post-watering and drying
  • a device for developing microfilms in which the film to be developed passes through a track consisting of guide rollers and the roller track through further guide and deflecting rollers to form a closed path from an endless, driven belt webbing, in particular a reinforced one Chemical-resistant plastic film belt or similar conveyor belt is designed, on which the film to be developed is attached to the inlet into the developer bath and is released from it before winding up the fully developed and dried film.
  • the microfilm to be treated runs through the individual baths, with the liquids washing around the microfilm on both sides.
  • the conveyor belt is held on a frame with all the rollers, the drive, the unwinding and the reeling bearing for the microfilm and can be inserted and removed with it in the individual baths or work stations.
  • This measure allows the development device to be taken apart in a simple manner, so that the individual baths or work stations and also the transport devices can be cleaned or bath liquids can be added.
  • the individual bath fluids must be exchanged and the baths cleaned.
  • Special containers are required for the removal of used liquids and the fresh and unused liquids are also stored in their own containers.
  • microfilms have no perforations for film transport on the longitudinal edges. For these reasons, it is known to pull the film through the baths with the aid of rollers that grasp the film from its front and back.
  • a slip acts on the film, i. H. a tangentially directed force, which in particular has an adverse effect on the film layers softened by the various liquids. This can cause damage to the film layers.
  • the invention has for its object both to simplify the film guide system within the device and at the same time to transport the film safely and gently through the device as well as to improve and simplify the circuit with respect to the fresh and unused liquid and the used liquid to be discharged in such a way that half the number of transport containers for these chemicals is eliminated.
  • Another object of the invention is to reduce the dimensions of the baths of the individual work stations and thus to reduce the consumption of chemicals.
  • each bath of a work station has a liquid and film guide body with an H-shaped cross section, the lateral vertical support walls of which are arranged on or slightly above the floor of the bath of the work station and are at a distance from each other that is slightly smaller than the width of the film, with longitudinal and continuous grooves arranged in the vertical support walls for guiding the film above the crossbar and the crossbar with a central bore directed towards the underside of the film surface is provided for the liquid supply, and that the roller pair leading the microfilm through all baths is arranged in the transport direction in front of the baths.
  • the liquid and film guide bodies advantageously have a length which is in each case smaller than the length of the baths of the workstations, so that the liquid flowing from the bore onto the crossbar reaches the bottom of the bath and into the feed pipes.
  • a crossbar is arranged between the vertical support walls of the liquid and film guide bodies above the film guide grooves.
  • the device shown in Figure 1 is located in a housing, not shown, whose front flap releases the vessels 2, 3, 4 and 5 in the open state.
  • the vessels 2 and 5 are designed as vessels that can be closed with a screw cap.
  • the vessel 2 serves to supply the work station 16 with developer solution and the vessel 3 contains a fixing solution to supply the work station 17.
  • the vessels 4 and 5 supply the work stations 18 and 19, which are used for primary and main watering and therefore contain appropriate watering agents.
  • Each vessel 2 to 5 is connected to a corresponding intake pipe 10, 11, 12 or 13.
  • the suction pipes lead to a liquid pump 14, which has four suction and four pressure chambers.
  • the pipes 40, 41, 42 and 43 running on the pressure side of the liquid pump 14 pass through a heater 15, which will be explained in more detail later with reference to FIG. 2.
  • the individual workstations 16, 17, 18 and 19 are constructed in principle in the same way, with the exception of an upper crosspiece, which will also be discussed in more detail later, so that it is also sufficient to understand the device if the workstation 16 is described in detail as an example . 3 is used at the same time.
  • the entire work stations including the drying station 47 are covered by a removable cover part 1 during the work process.
  • a liquid and film guide body 20 is arranged, which has an H-shaped cross section, the vertical supports 24 and 25 of which lie on the floor 26 of the bath of the work station Support 16.
  • the distance between the vertical supports 24 and 25 is slightly smaller than the width of the film 31 (see FIG. 3).
  • grooves 33 and 34 extending in the longitudinal direction are provided in the vertical supports 24 and 25 above the crosspiece 32.
  • the crosspiece 32 is provided with a central bore 35 directed towards the film surface, which is connected to the pressure tube 40.
  • the length of the liquid and film guide body 20 is less than the length of the bath of the work station 16, so that the developer solution flowing from the bore 35 onto the crossbar 32 reaches the bottom 26 of the bath and the feed pipe 6, which is connected to the vessel 2 connected is. Since the length of the liquid and film guide bodies is less than the longitudinal extent of the baths, the film between the individual baths is completely exposed, so that the liquid is not carried over from one bath to the subsequent bath.
  • the grooves 33 and 34 in the vertical supports 24 and 25 are dimensioned such that the film 31 receives sufficient play.
  • the film 31 is guided approximately at a distance of 2 to 3 mm above the crosspiece 32, so that there is an extremely small space through which liquid flows. This brings the underside of the film into intensive contact with the developer solution.
  • a transverse web 36 and 37 are located in the work stations 16 and 19 between the vertical supports 24 and 25 of the liquid and film guide bodies 20 and 23 above the film guide grooves 33 and 34.
  • the rollers 45 and 46 are driven by gears 49 and 50 by means of a transmission 51 from the motor 52.
  • the transmission 51 also actuates the film winding roller 53 and two drying rollers 54 and 55 via its gears 53 and two drying rollers 54 and 55 via its gears 56 and 57. No drive is required for the film reel 58, since the pair of rollers 45 and 46 remove the film from the Roll 58 rolls and ' pushes it through the film guide grooves 33 and 34.
  • the heater 15 consists of an electric heating element 39, which is surrounded by the pressure pipes 40, 41, 42 and 43 at a distance. This space is filled with quartz sand, which is enclosed by the jacket 35.
  • the pressure pipe 40 is connected to a temperature controller 44 which controls the heating power of the electric heating element 39 with the aid of an electronic circuit.
  • the liquid pump 14 and the heater 15 are switched on, so that a continuous liquid circulation is started before the film 31 is in the device.
  • the motor 52 is actuated and the film 31 is fed to the rollers 45 and 46, which grip it and guide it through the film guide grooves 33 and 34 of all liquid and film guide bodies 20 to 23. If the film reaches the liquid and film guide body 20, it cuts through the liquid flow, the upper transverse web 36 ensuring that a liquid space is also formed above the film. Since the film 31 has sufficient play in the grooves 33 and 34, the capillary action ensures that an adequate flow and thus renewal of the liquid is also formed. As already mentioned at the beginning, it is only necessary to provide upper transverse webs 36 and 37 if the upper film side is to be wetted. In the other cases, the upper crossbars can therefore be omitted.
  • Vessels 2 to 5 perform three different functions. So they serve once for the transport of the still fresh liquid, form a storage tank within the device, which is located in the circuit of the respective liquid and also serve for the removal of the used liquid. In Ver half of the number of vessels is therefore eliminated in comparison to the previously known devices. A laborious cleaning of the storage tanks is no longer necessary. Within the workstations there is the advantage that they can be dimensioned relatively small because of the intense flow, while still having a constant effect on the film. Overall, there is the advantage that the device according to the invention can be used not only in the usual laboratories, but also in other rooms that do not have any special facilities, as are common for laboratories, since no pollution of the environment by cleaning processes Device can occur.
