Definitions

  • the present invention relates to photographic printing and more particularly to an interfacing device making it possible to connect, to a printer, a very large capacity package.
  • the subject of the invention is an interfacing device capable of adapting to the packaging described in the French patent application filed on June 8, 1990 and entitled "Packaging of photographic products in strips”.
  • Document DE-A-3 034 083 describes a processing machine in which a loop is formed between the tape cassette and the inlet of the machine which is regulated by means of a cell.
  • the objective pursued by the formation of this loop is to allow transverse displacement of the strip while avoiding the risks of abrasion of the surface of this strip.
  • the disclosed device makes it possible to overcome the tensile force to be exerted on the strip during operation, but the introduction of the strip into the printer is not automatic and a large part of this strip is veiled.
  • the invention also relates to an interfacing device aiming not only to overcome the tensile force to be exerted on the strip to move it but at the same time to avoid veiling the photosensitive strip over a significant length and for which feeding is practically automatic.
  • the interfacing device 10 is used to connect a debtor station 11 (of which only the part cooperating directly with the device according to the invention) in a light-tight manner to a receiver station 12 (of which only the supply port 13 is shown).
  • the debtor station 11 is used to deliver a strip 153 of photosensitive product and can take the form of the packaging described in the French patent application filed by the plaintiff on June 8, 1990 and entitled "Packaging of photographic products in strips”.
  • debtor 11 comprises at least one outlet slot 14 delimited by an upper lip 15 and a lower lip 16.
  • the receiving station 12 can be by example a photographic printer which comprises a feeding system making it possible to exert a given tensile force on a strip introduced into the feeding orifice 13 of the printer.
  • the interfacing device comprises a light-tight housing 30 provided with an inlet 31 and an outlet 32.
  • the outlet 32 is provided with a first arrangement consisting essentially of the lips 20 disposed at the outlet of the device.
  • the lips 20 are designed so as to cooperate with the supply orifice 13 of the receiving station in order to obtain a light-tightness when the lips 20 penetrate into the supply orifice 13.
  • the inlet 31 is provided with a second arrangement making it possible to connect the device according to the invention to the debtor station 11.
  • the lips 15 and 16 of the debtor station 11 have, for example, grooves 21 surrounding the strip 153 exiting through the slot 14.
  • the interfacing device has a complementary part 22 to the grooves 21 designed to cooperate with the grooves so that, during operation, the cooperation of the grooves 21 and the complementary part 22 ensure a light tightness.
  • the complementary part 22 is fixed on a movable member 23.
  • the member 23 slides on columns 24 secured to the housing 30; it is connected to the housing 30 by means of a bellows 25 making it possible to maintain the light-tightness.
  • the preferred debtor item is similar to the packaging described in the French patent application filed on June 8, 1990 and entitled "Packaging of photographic products in strips”. This package includes several individual strips arranged next to each other and leaving the package through the light-tight slot 14. As indicated in the aforementioned request during the use of the packaging, the latter is displaced by the distance equal to that between the longitudinal axes of two strips to use the next strip when a strip is finished.
  • the movable member 23 slides on the columns 24 between on the one hand a retracted position in which the device does not cooperate with the debtor station and in which one can introduce a strip leaving the debtor station in said device and on the other hand a deployed position in which it cooperates with the debtor station to ensure, in operation, the light tightness.
  • this movement simplifies the mechanism for correctly positioning the debtor station. In fact, the latter needs to be located with reference to the interfacing device and the movement of the movable member makes it possible to limit the positioning accuracy of the debtor station to two dimensions.
  • the device according to the invention also comprises a drive device 40 provided with a motor 41 connected to a drive roller 42.
  • the drive roller is associated with a pressure roller 43 biased by springs 44 so as to come in contact with the drive roller 42. Downstream of the drive device, there are curved guides 45 delimiting a chute 47 through which the strip of photosensitive paper is passed.
  • the movable member 23 is placed in its retracted position in order to provide a space between the interfacing device 10 and the debtor station 11.
  • a cam 46 carried by the movable member 23 cooperates with the pressure roller 43 to move it away from the drive roller 42 and provide a free space between the drive roller or motor 42 and the pressure roller 43.
  • the movable member 23 is again placed in the deployed position.
  • the complementary part 22 cooperates with the grooves 21 ensuring the seal.
  • the pressure roller 43 no longer in contact with the cam 46 and being biased by the springs 44, presses the strip on the drive roller 42.
  • the motor 41 is then excited which has sufficient torque to extract the strip from the slot 14 of the debtor station 11.
  • the strip then enters the chute 47 and reaches a mobile carriage 48, guided for example on a rod 70 and provided with a roller 49 free in rotation and a deflector 50.
  • the movable carriage 48 is in the high position (in broken lines) so that the deflector 50 directs the strip over a roller 51 for deflection towards a second pair of guides 52.
  • This second pair of guides directs the strip towards the outlet 32 between the lips 20.
  • a detection system (not shown) indicates the exit of the strip between the lips 20.
  • a time delay or any other means can be used equivalent.
  • the carriage 48 is lowered while moving the strip by means of the driving roller 42 so as to form a loop 53.
  • the roller 49 serves to deflect the strip so as to form the loop while the roller return 51 allows to orient the strip towards the exit 32.
  • detection means shown diagrammatically by rocker switches 54 and 55 allowing the length of the loop to be known.
  • the detection means 54, 55 are connected to a regulation system 56.
  • the regulation system makes it possible to control the speed of rotation of the motor 41.
  • the motor 41 When the switch 55 is operated indicating that the carriage 48 is in its lowest position the motor 41 is stopped this which has the effect of reducing the length of the loop 53 when the printer drives photosensitive product in a strip.
  • the motor 41 moves the strip at a speed close to the speed required for correct operation of the printer and when the switch 54 indicates that the carriage is towards at the top, the motor drives the tape at a much higher speed than that of the printer.
  • the loop thus defines a means for limiting the tensile forces necessary for the extraction of the strip.
  • the motor 41 serves to supply the strip and the loop serves to control this delivery.
  • the interfacing device 10 according to the invention serves as an adapter between the traction forces. This device makes it possible to supply a printer equipped with a low traction force supply device with a debtor station for which the traction force necessary to extract the strip is greater than the traction force likely to be exerted by the photographic printer.
