Definitions

  • ABSTRACT A developing automat with an inner transportation device for sheet films, is provided with a device consisting of at least one store magazine and a holder for the magazine fixed to the automat.
  • the invention is particularly characterized in that the supply magazine is provided with a device for removing individually film sheets located in the magazine as a pile of sheets lying directly one upon the other.
  • the supply magazine is also provided with means actuating the film removing device by the transportation device of the automat.
  • This invention relates to a device provided for a developing automat having inner transportation means for sheet films.
  • the device consists of at least one store magazine and a holder for the magazine which is fixed to the automat.
  • Photographic films cut as sheets are used a great deal in X-ray techology.
  • the problem arises as to how to supply in a simple manner to a developing automat exposed film sheets dropping stepwise out of sheet film photographing cameras partly in slides, but at the pres ent time more and more in receiving magazines.
  • a device is also known wherein loose film sheets are introduced automatically into an automatic developing machine provided with an inner film sheet transporting device.
  • the drawback of this construction is that the developed films must be stuck one after the other into the spaces of a fan-like magazine.
  • a developing automat having an inner transportation device with a supply magazine having a device for removing individually film sheets located in the magazine as a pile and means operating the-film removing device by the film transportation device of the developing automat.
  • This makes it possible to remove in a single operation the entire batch of sheet films to be developed located in a film receiving slide of an X-ray examining device and to bring it as a batch into the supply magazine without it being necessary to place the individual sheet separately.
  • These film sheets then can be removed automatically by the developing automat corresponding to its treating speed.
  • the insertion capacity of the device can be further substantially increased if the holder is so constructed that the store magazine can be transported into a so- 2 called charging position for being charged with films of different sizes.
  • the supporting surface for the film sheets in the store magazine is inclined by at least to the horizontal and has its inclination maximum approximately along its diagonal; in it the calibrated part of the removing slit is arranged upon a side of the slit while the suction head is arranged in the corner of the magazine assuming the lowest location in the charging position.
  • This construction of the holder provides that when the store magazine is supplied with a pile of films of different sizes, all films will have a definite position in the magazine.
  • FIG. 2 is a sectional view of a store magazine coupled to a developing automat.
  • FIG. 4 is a front view of a store magazine from the side of the removing slit.
  • FIG. 1 shows a developing automatic 1 having a store magazine 2 for sheet films which is connected airtightly at the side from which the films are introduced.
  • a second similar store magazine 3 is located at one of two possible charging locations 4 and 5 to the side of the developing automat.
  • a guide track 6 serving as a holder for the magazines is located at the film introducting side of the developing automat.
  • the two store magazines 2 and 3 are movable upon the track from a discharge location 7 into one of the two charging locations 4 and 5.
  • the two magazines are provided on two sides with separate guide pins 8 and 9. Each of these guide pins is in engagement with one of the guide grooves 10 or 11 provided in the track 6.
  • the guide grooves are bent as both ends of the track to the extent of about 45 relatively to the longitudinal axis of the track, so that when the magazines 2 and 3 are shifted along the track they will turn to the extent of 45 relatively to their surface direction shortly before reaching the charging locations 4 and 5.
  • the turning direction is the same for both charging positions.
  • the two magazines are coupled with each other in the moving direction (not illustrated) so that when a magazine is located in the discharging location 7, the other magazine will be located in one of the charging locations 4 or 5..
  • FIG. 2 shows in a partly sectional view the cooperation of the developing automat 1 with a store magazine 2 light-tightly coupled with its supporting slit 12.
  • a partly calibrated removing slit 14 the width of which in the calibrated portion is about 1.3 times the thickness ofa film.
  • the calibrated removing slit 14 can be closed by a closure 15 which is opened automatically by a stop provided upon the track during coupling to the introducing slot 12 of the developing automat l.
  • the casing of the magazine has a cover 16 through which film sheets 17 can be introduced.
  • FIG. 4 shows a side view of the magazine 2 from the side of the withdrawing slit 14, the closure 15 being shown as raised. It is apparent that only that side of the withdrawing slit which is located opposite the suction head 19, has a cal-ibrated thickness The remaining part of the withdrawing slit is wider.
  • the covers of the supply magazines as slides and to adapt the dimension of the'supply magazines to the receiving slides of the cameras so that they can be placed light-tightly upon the upper edge of the supply magazines. if then the base ofthe receiving slides is also constructed as a slide, then the charging of the supply magazines can take place at daylight merely by pulling the two slides.
  • a device comprising at least one receiving magazine for exposed film sheets and a holder connecting said magazine to said developing machine, said magazine having a rectangular film sheet supporting surface ane a device removing individually film sheets located in a pile upon said film sheet supporting surface, and means driving said removing device and actuated by said film transporting device, said holder comprising means shifting said magazine from a discharging position into a charging position in which said supporting surface is inclined at least by 25 to the horizontal, and wherein said magazine is turned about the normal to the supporting surface, so that one corner of said supporting surface as sumes the lowest position of all the four corners to position one corner of all said film sheets in said one corner regardless of the size thereof, said corner being close to said removing device.
  • a device comprising at least one receiving magazine for exposed film sheets and a holder connecting said magazine to said developing machine, said magazine having a rectangular film sheet supporting surface and a device removing individually film sheets located in a pile upon said film sheet supporting surface and means driving said removing device and actuated by said film transporting device, said removing device comprising an at least partially calibrated withdrawing slit in the plane of said film sheet supporting surface, a suction head projecting into the same plane, and means moving said suction head toward said slit and back from said slit, said holder comprising means shifting said magazine from a discharging position into a charging position in which said supporting surface is inclined at least by 25 to the horizontal and wherein said magazine is turned about the normal to the supporting surface, so that one corner of said supporting surface assumes the lowest position of all the four corners to position one corner of all said film sheets in said one corner regardless of the size thereof, said corner being close to said calibrated portion of the withdrawing slit and
  • a device in accordance with claim 2 comprising a feeler located in the path of the film sheets close to said film introducing slit, said feeler setting in motion said means for driving said sheets removing device each time a film sheet has passed it.
