Definitions

  • the invention relates to a treatment device for photographic substrates, in which a substrate is treated in a treatment tub which can be filled with treatment liquid by means of a bottle and can be refilled from the used treatment liquid into the same bottle.
  • Devices of the type mentioned are known in various variants, for example from DE-OS 34 02 506 or DE-GMS 87 11 858. There are special pumping systems in the device for filling them from the bottle and for emptying them back into the bottle required.
  • the invention is based on the object of being able to effect the filling, refilling and emptying of a device mentioned at the beginning by means of the same bottle without a pump system.
  • the filling and refilling of a treatment tub and its emptying can only be effected by rotating a connected bottle by approximately 180 ° from bottom to top and vice versa.
  • a simple mechanical design of the treatment device without a pump device is possible with clean operation without the risk of spilling treatment liquid, the level of the treatment liquid in the treatment tub also being ensured without any additional level monitoring devices, such as probes.
  • FIGS. 1 and 2 designates a housing of a development device into which a development trough 2 is inserted.
  • Housing 1 and development tub 2 can have any known shape, the housing 1, as shown in FIGS. 3 and 4, being in two parts and having a removable cover 1a.
  • Slots 1b and 1c can be provided in the housing 1 for introducing and carrying out the substrates to be treated and any known transport and / or guiding means 3, 4 for guiding and moving the substrates through the trough 2.
  • the invention can also be used for any differently designed device with a relatively flat treatment trough, in which case, for example, a layer support could also be inserted into the trough by hand.
  • the design of the means of transport is also not important.
  • the type of filling and emptying of the treatment tub 2 is essential.
  • the treatment liquid is packaged in a bottle 5 from which it can run into the tub 2.
  • the used treatment liquid is then left in the same bottle 5, without the latter being uncoupled from the device 1 or trough 2.
  • an inlet and outlet connection 6 is attached to a side wall 2a of the tub 2, namely either connected in a liquid-tight manner or molded on from plastic, for example.
  • the tub-side opening 2b which is surrounded by the inlet and outlet connector 6 and can best be seen in FIG. 4, can be smaller than the free flow cross section of the inlet and outlet connector 6. It is essential, however, that the height h of the opening 2b is equal to the height of the treatment liquid bath provided in the state of use.
  • the trough bottom it is also possible for the trough bottom to have a partially cylindrical, curved shape which is adapted to the path of movement of the layer supports to be treated, and is delimited by vertical or outwardly inclined, flat side walls 2a. In this case, the lower edge of the opening 2b must be flush with the deepest point of the tub floor. If, on the other hand, a bowl-like or pan inclined in several directions is provided, this would have to have a groove from its deepest point to the lowest point of the opening 2b, which is inclined at least horizontally, but preferably somewhat downwards.
  • the bottle 5 is now so liquid-tight and rotatable that in its normal position, in which its closure 7 looks up, the liquid in it is below the level of the opening 2a and in a second position is above the level of the opening 2a.
  • the easiest way to achieve this is to arrange a knee-shaped nozzle 8 between the tub-side inlet and outlet nozzle 6 and the closure 7, the bottle 5 together with the knee-shaped nozzle 8 being approximately 180 ° around the tub-side inlet and outlet nozzle 6 is rotatable.
  • the closure 7 and the nozzle 6 and 8 can be connected in any known suitable manner. Thus, as indicated in FIG.
  • a spring 9 can be compressed, thereby opening a bottle valve (not shown) which is also known in many embodiments.
  • the knee-shaped connector 8 can be connected to the inlet and outlet connector 6 via a rotatable plug connection with sealing rings 10. But screw connections could also be used.
  • the bottle 5 together with the knee-shaped neck 8 is rotated 180 ° upward, so that its open closure 7 looks down.
  • the treatment liquid now flows into the tub 2 through the tub-side opening 2b until the tub is filled up to the upper edge of the opening 2b.
  • the liquid supply into the tub 2 ceases, so that not only filling of the tub 2, but also an exact metering of the treatment liquid in the tub is achieved by the arrangement described. If treatment liquid is consumed by the treatment of the layer supports and possibly also by evaporation, fresh treatment liquid flows from the bottle 5 again until the liquid level, which is defined by the upper edge of the opening 2b, is reached again.
  • the bottle 5 is turned back again by approximately 180 ° into the position according to FIGS. 1, 3 and 4.
  • the used treatment liquid can now run out of the tub 2 through the opening 2b into the bottle 5 located below.
  • the knee-shaped neck 8 is removed from the tub-side neck 6 and closure 7 and closed again, so that the used liquid can be disposed of in the bottle 5 without risk of spillage or other contamination of the environment.
  • the knee-shaped neck 8 could be connected to a bottle 5 or the tub-side neck 6 if necessary. The order would then be bulky.
  • simple closures are provided at the ends of the knee-shaped connecting piece 8 and the tub-side connecting piece 6, the sealing of which prevents dripping of liquid on the connecting piece when it is decoupled.
  • the bottle 5 does not necessarily have to be turned upwards by 180 ° to fill the tub 2; it is sufficient if its closure 7 lies above the upper edge of the opening 2b.
