Definitions

  • the invention relates to a device for conveying photosensitive photographic Films from cartridges according to the preamble of claim 1.
  • Such a device is e.g. B. known from DE-PS 41 26 579, where a single Insert option for film cartridges with to be wound into the development facility Movies is provided.
  • a single Insert option for film cartridges with to be wound into the development facility Movies is provided.
  • the operator is always present on the device when a Film was fully fed into the processor. Only the lid to the unwinding chamber can be opened to close the empty cartridge remove and insert a new cartridge and the beginning of the film in one introduce appropriate conveyor. For one, this requires a high one Presence and concentration of the operator, on the other hand is inevitable lost time by changing the two cartridges, which is clearly adversely affects the utilization of the development facility.
  • EP 242 817 A1 shows a magazine for holding several leader cards two film protrusions protruding from cartridges are attached.
  • the Leader cards can be sequentially fed to a film processor the films hanging on the leader cards from the cartridges and pulls through the treatment baths. This way, a couple of films processed one after the other until the magazine is empty. Only then can it be opened and refilled, so that a complete Operation is only possible to a limited extent. It is also not possible with this magazine insert a film that needs to be edited quickly into the magazine if processing of the films in it has already started.
  • US-A 5 308 005 describes a device for perforating film material, as used for example in the production of 135 film becomes. After the casting process, the film material is available in wide bands, which first have to be cut into smaller strips. This narrow Strips are then wound up in large rolls and in the cassettes shown sealed light-tight. In order to be able to continuously perforate these films, the individual rolls of film are connected to each other in a splicer and via a buffer with which the time span of the splicing process can be bridged, fed to the actual perforator.
  • the invention has for its object a film conveyor of the beginning described type so that the operator enough Has time to insert the next film without developing capacity remains unused and therefore requires a great deal of effort becomes.
  • the guide arrangements for the introduction of the Film are brought together like a switch in front of the film processor, it becomes possible to alternately insert films into the unwinding chambers each time the developing device has almost no gap between the film and film or film and leader card are fed when the film from the other unwinding chamber is fully extended.
  • the operator has so that there is as much time available for loading the other unwinding chamber as is necessary to pull the film out of the first film cartridge. This is with achieved a comparatively modest effort because the unwinding chambers can be largely the same and a comparative one require little mechanical effort.
  • the order is Placement in the unwinding chambers as desired, so that any preferential treatment is possible is.
  • Fig. 1, 1 is a light-tight housing on the inlet side of a continuous film processor referred to, which according to the teaching of DE-OS 41 26 579 directly with a device for copying photographic Filming on copy paper and a downstream developing device can be assembled into a structural unit.
  • the invention is in equally applicable if it is a self-employed or single Film processor 7 is. This itself is not in detail shown; it can be of conventional construction with racks for rollers and side guides exhibit.
  • the side guides can only be processed with one Film width, e.g. B. the format 135, directly in the side cheeks rack boards.
  • leader cards are attached with the side guides in the film processor are adapted to the width of the leader cards.
  • the described invention is the same for both embodiments of development devices applicable.
  • Fig. 1 The embodiment shown in Fig. 1 is for the use of leader cards 10 equipped at the leading edge of the films.
  • the housing 1 has a shape on the insertion side for the film cartridges, which allows the accommodation of two unwinding chambers 2 and 3. Under the horizontally extending section is located at the upper end of the housing 1 an opening which can be closed by a cover 1b. Below is the unwinding chamber 3, one along a vertically downward path Cartridge holder 3a for film cartridges 9, below the pull-out mouth the cartridge the through opening of a separating knife 3b and one Conveyor 3c are arranged; the latter consists of a driven one Roller and a counter pressure roller.
  • the drive roller can e.g. B. with a stepper motor be connected by a control device to be described is controlled.
  • the separating knife 3b can e.g. B. for the film tension on the cartridge holder 3a by a sensor be controlled so that when you tighten the film at the end of the film the cutting process triggers.
  • This unwinding chamber which in turn is connected to the housing 1 in a light-tight manner contains the same elements as the unwinding chamber 3, namely a cartridge holder 2a, a separating knife 2b, a conveyor 2c and an unwinding opening, which can be closed by a flap 2d.
  • a film sensor 5 Corresponding film sensor 4. Behind the film sensor 4 follows in the transport direction a soft-like merging 6 of the two guide grooves of the unwinding chamber 2 and the unwinding chamber 3, so that after this merge Leader cards 10 are promoted in the same way in the film processor.
  • a control device 8 - z. B. receives a microprocessor the signals of the film sensors 4 and 5. Furthermore, it receives pulses of Stepper motors in the conveyors 2c and 3c, so that each according to certain Events covered by transport routes through the conveyor systems are known in the control device 8.
  • the control device 8 now activates 2 alternately six different elements always in groups: Starting from the state of movement according to FIG. 1 in the unwinding chamber 2, the flap 2d for the unwinding opening is open, the flap 1a on locked the access opening to the unwinding chamber 2 and the transport device 2c activated.
  • the conveyor 3c de-energized and the flap 3d closed.
  • the operator can open the flap 1b and insert a cartridge 9 with a leader card 10 attached to the beginning of the film by inserting this card into the transport rollers of the conveyor 3c into the unwinding chamber and close the flap 1b.
  • the controller 8 can ensure that in each case the just minimal distance between the end of the leading Film and the next leader card 10 is observed.
  • the flap 1a is unlocked by the switching processes and by the green one Illuminated display prompts the operator to remove the empty cartridge 9 and insert a new cartridge with leader card, so that after the Passing the end of the straight from the unwinding chamber 3 Film the switching process take place in the opposite direction and therefore the next film can be updated immediately.
