Definitions

  • the invention relates to a device for the light-tight insertion of a film stacking container according to the preamble of claim 1.
  • the object of the invention is to provide an easy-to-use and secured against light incidence insertion for film stacking processing devices in film processing.
  • the parallel guidance ensures at all times that the parallel light seals between the cover for the insertion slot and the hood of the device, on the one hand, and between the hood and the light sealing means on the film stacking container, on the other hand, incorrect exposures prevent the films in the film stacking container as well as inside the film processing apparatus.
  • Fig. 1, 1 denotes a light-tight cover, which sits on a film processing device, not shown, within the z. B. exposed film is introduced into a film stacking container 16 or removed therefrom and fed to a developing machine.
  • this film processing device corresponds to a processing device according to FIG. 2 of German patent application P 31 22 583.7.
  • this processing device there are means for introducing sheet films such as roll sets and means for individually removing sheet films from a film stack within the film stack container 16 with moving suction cups and roll sets, which, however, are not the subject of the invention and are therefore not shown.
  • an insertion slot 2 for a film stacking container which is shown in more detail in FIG. 2, is provided in the top in the longitudinal direction.
  • the opening at the base of the insertion slot 2 is closed by a cover 6, which can be displaced in parallel to the interior of the device by means of suitable guide means and prevents light from entering the device by means of suitable light sealing means to the hood 1, as long as no film stacking container 16 is inserted into the insertion slot 2.
  • FIG. 2 shows the film stacking container 16, which is described in more detail in German patent application P 31 22 582.9 and which essentially consists of a box-like film stacking carrier 17; a handle bar 18 arranged thereon with a handle 18a and a sliding tube 19 movably arranged on the film stack carrier 17.
  • the film stack carrier 17 is closed on all sides and has an opening 20 on at least one flat side in the lower part opposite the grip strip, which opening extends over the entire width and at most half the height of the stack carrier.
  • films deflected from below can either be introduced and assembled into a film stack 21 by being placed on the base of the film stack carrier 17, or they can be removed individually again by a combination of suction cups which engage through the opening 20.
  • Such openings 20 can therefore also be arranged on both sides of the film stack carrier 16.
  • the handle 18 is used for transporting, pushing in or pulling out the film stacking container.
  • the slide tube 19 has a cuboid shape and has a rectangular inner cross section which surrounds the film stack carrier 17 so closely that the slide tube can still be moved on it, but largely prevents the incidence of light into the opening 20.
  • the sliding tube 17 provides a double wall 24 which extends within the opening 20 and on the two narrow sides and is attached to the underside of the sliding tube.
  • the side walls 17a and the top wall 17b of the film stack carrier 17 then run between the double wall 24 and the outer wall of the sliding tube 19.
  • a rocker 26 is arranged, which has a pawl 27 facing the film stack carrier.
  • a compression spring 28 is inserted between the slide tube 19 and the pawl 27 and presses the rocker against the film stack support 17.
  • the other end of the rocker 26 is arranged in the region of a bore 19b of the slide tube, such that an incident actuator, which is still based on FIG is described in detail, meets the rocker end.
  • a recess 29 is provided on the side facing away from the grip bar 18, into which the pawl 27 falls due to the force of the spring 28, provided that the sliding tube 19 is in the closed state, as shown in FIG. 2 is shown.
  • the slide tube 19 In the transport state, the slide tube 19 is located on the film stacking container in the lower end position shown in FIG. 2, as a result of which the openings 20 are closed light-tight.
  • the opening 20 In order to be able to insert films into the film stacking container or to be able to remove films therefrom, the opening 20 must be exposed by moving the sliding tube 19 upwards relative to the film stacking support.
  • the means shown in FIGS. 3 and 4 serve for this purpose.
  • the lid 6 has essentially a box-like shape, which is open at the bottom.
  • the upper cover surface serves as a support for the underside of film stacking containers inserted into the insertion slot 2.
  • Various break-out ribs are arranged on the underside of the film stack carrier 17, which cooperate with mushroom-like sensors 7, which in turn are pushed upwards by springs 9 within recesses 6a.
  • the position of the sensor 7 is sensed by light barriers 8 mounted inside the cavity of the cover 6, so that different processing programs can be made effective depending on the type of film stacking container.
  • On the upper edge an upwardly directed, double edge 6a is provided all around, which represents part of a light-proof labyrinth.
  • the corresponding light seal 5 is arranged on the inside of the opening of the insertion slot 2.
  • This light seal is also effective when the cover 6 is lowered with its circumferential recess relative to the seal 5 on the inside of the hood by a constant amount.
  • a circumferential, upwardly directed sealing edge 4 is arranged, which dips into a corresponding groove 19c of the sliding tube 19 when the lower band of the sliding tube sits on the sealing edge 4.
  • the lateral boundaries of the insertion slot 2 are slightly chamfered in the sense of an insertion aid.
  • the right guide edge in FIG. 4 for the narrow side of the film stacking container has only about half the height of the guide edge on the other side and is additionally beveled in order to form a tilting support 3 for the tilting removal of the film stacking container from the insertion slot.
  • the unlocking arrangement for the locking elements 25 is accommodated in the hood 1 in the region of the guide edges of the insertion slot 2 for the side faces of the film stacking container.
  • a pot-like spring housing 12 there is a compression spring 11 which presses a tiltable unlocking bolt 10 into the opening of the spring housing.
  • the unlocking bolt is dimensioned such that when it is juxtaposed with the bore 19b it lifts the rocker 26 and thus cancels the locking between the sliding tube 19 and the film stack carrier 17.
  • the bore 19b lies above the unlocking bolt 10 by a certain amount, so that the locking connection between the slide tube and the film stacking support is still maintained.
  • the height offset between these elements corresponds approximately to the distance between the labyrinth elements 4 and 19c.
  • FIGS. 3 and 4 Guiding and driving the cover 6 result from FIGS. 3 and 4.
  • the z. B. can carry the drive of the suction cups and the rollers for transporting the films.
  • two double racks 40 and 41 are attached centrally and vertically to these boards, in particular injection-molded in one piece with plastic boards.
  • a toothed wheel 36, 37, 38 and 39 meshes with these toothed racks, which are rotatably supported in the cover 6 by means of shafts 34, 35 and are rigidly connected to one another in pairs.
  • a motor 15 is also arranged in the interior of the cover and drives the two shafts 34 and 35 in opposite directions via a pinion 30 and an intermediate wheel 32 as well as drive wheels 31 and 33. The motor 15 can be reversed in its direction of rotation.
  • stops 42, 43 are attached, which fix the cover 6 in its lower end position by supporting the lower edges.
  • a light-tightly closed film stacking container according to FIG. 2 is inserted into the hood 1 of the film processing machine by means of the insertion bevels at the lateral boundaries of the insertion slot 2.
  • the underside of the film stack carrier 17 lies on the top of the lid 6 and actuates the sensor 7 corresponding to the ribs on the underside of the film stack carrier 17.
  • the control means therefore contain a coded indication of the type of film stack container via the light barriers 8, e.g. B. whether films should be imported or removed, and what type the films are.
  • the starting position corresponds to the position drawn in solid lines in FIG. 1.
  • the motor 15 rotates briefly in the direction of rotation to raise the cover 6, although it is already in its upper end position.
  • the lifting pins 14 are released from contact with the bores 22a and 3a and can be easily withdrawn by energizing the lifting magnets 13.
  • the interior of the device is closed in a light-tight manner by the light seal 6a, 5, while the openings 20 of the film stacking container 16 are closed in a light-tight manner by the sliding tube 19.
  • the direction of rotation of the motor 15 is reversed and the cover, which is only supported by the toothed wheels 37, 38 and 39.40 in engagement with the toothed racks 40, 41, moves downward in accordance with the engine speed.
  • the light seal 6a, 5 is moved apart to the same extent all around because of the precise parallel guidance of the cover, while the sealing parts 19c, 4 approach each other until this light seal becomes effective.
  • the bore 19b of the slide tube 19 reaches the unlocking bolt 10, so that the rocker 26 is unlocked on both sides by the action of the spring 11 and the slide tube 19 can move relative to the film stack carrier 17 .
  • the sliding tube 17 is also seated on the sealing edge 4 on the outside of the insertion slot 2.
  • the film stack carrier 17 follows under the effect of the dead weight of the movement of the cover and thus shifts relative to the held sliding tube 19. Due to the light seal of the sliding tube 19 relative to the hood 1, both the inside of the device and the device are now the inside of the film stacking container 15 opened by progressively opening the opening 20 is shielded from the outside light.
  • the progressive lowering movement of the cover 6 ends when the lower band is placed on the stops 42, 43.
  • the motor drive can then be stopped.
  • the openings 20 on the side surfaces of the film stack carrier are now freely accessible for introductions or film withdrawals when the film stack carrier 17 has now reached the position shown in broken lines in FIG. 1.
  • the described design of the guide and drive of the cover 6 with the central double rack and the rigidly connected gears ensures an absolutely parallel movement in the longitudinal direction of the cover, which is extremely important because of the light protection.
  • This design is also very inexpensive to manufacture and has the further advantage that after lowering the cover 6 in the position shown in dashed lines in FIG. 1, the space above the cover 6 is completely free for access by the suction cups and the guide rollers and other elements for insertion or Removing sheet film is.
  • This design of the guide can also be used if the movement takes place in the horizontal direction and the stacking container 17 of the cover takes place under the action of external force such as being pushed in by the operator or by coupling to the cover. If, after all or when the film stacking container has been emptied, it is to be removed again, the motor 15 is set in motion in the opposite direction of rotation to the lowering movement. When the closed position between the slide tube and the film stack carrier is reached, the lower edge of the slide tube 19 rests on the projecting edge of the film stack container and is lifted by it. As a result, the rocker 26 comes from the area of the unlocking bolts 10 and the locking between the slide tube and the film stack carrier 17 takes effect. On this last part of the lifting movement, the sealing function passes from the groove 19c / edge 4 again to the seal 5 / 6a, so that the interior of the device is protected against the incidence of light, regardless of the presence of a film stacking container.
  • the relatively heavy film stacking container which is located in the insertion slot on a possibly higher device, can be removed by tilting, which is a very great ease of operation compared to a parallel removal upwards.
  • the locking between the sliding tube and the tube remains at the time of attachment Maintain the film stack carrier so that even incorrect operation - taking the film stack carrier by touching the slide tube - does not damage the films. This lock is only released when the cover has completed the first part of its way down by pressing a start button.
