Abstract

Abstract Apparatus for continuously processing film strips wherein the individual lengths of film are spliced into a substantially continuous strip which is passed through a film processor. The individual lengths of film are identified by use of a film identification conveyor that operates substantially in parallel with the film processor to convey a film identification envelope, from the input end to the output end of the processor. The film identification conveyor has a plurality of movable carriers, each arranged to accept an envelope. The conveyor presents only a single carrier at one time at the input end of the processing apparatus, and advances the carrier from the input end only after an envelope is inserted therein and the corresponding film is fed to the film processor. The carriers are advanced in synchronization with the film processor whereby a carrier and the corresponding processed film are delivered to the output end of the processor substantially simultaneously. The film processor and the identification conveyor operate in a manner which insures coordinated delivery of film on the corresponding envelope at the output end of the processor.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 212 words
Apparatus for sequentially processing a plurality of photographic materials each of which ordinarily is furnished to the apparatus with a separate identification member and each of which ordinarily is to be returned to the same member after processing, the apparatus comprising: means defining a plurality of photographic material processing stations including an initial station and a terminal station; photographic material transport means for conveying a plurality of photographic materials in an inalterable order through said processing stations from said initial station to said terminal station; identification member conveyor means having an input end adjacent said initial station and having an output end adjacent said terminal station, said conveyor means including a carrier for each of a plurality of said identification members, said conveyor means being operable to convey carriers from the input end to the output end of the conveyor means in an inalterable order; and means coordinating operation of the transport means and said conveyor means to effect conveyance of photographic materials on the transport means and Carriers on the conveyor means so that a particular photographic material is delivered at the terminal station of the transport means substantially when a carrier for the identification member, identifying the particular photographic material, is delivered at the output end of the conveyor means.
Claim 2
Dependent Claim 212 words
Apparatus for sequentially processing a plurality of photographic materials each of which ordinarily is furnished to the apparatus with a separate identification member and each of which ordinarily is to be returned to the same member after processing, the apparatus comprising: means defining a plurality of photographic material processing stations including an initial station and a terminal station; photographic material transport means for conveying a plurality of photographic materials in an inalterable order through said processing stations from said initial station to said terminal station; identification member conveyor means having an input end adjacent said initial station and having an output end adjacent said terminal station, said conveyor means including a carrier for each of a plurality of said identification members, said conveyor means being operable to convey carriers from the input end to the output end of the conveyor means in an inalterable order; and means coordinating operation of the transport means and said conveyor means to effect conveyance of photographic materials on the transport means and Carriers on the conveyor means so that a particular photographic material is delivered at the terminal station of the transport means substantially when a carrier for the identification member, identifying the particular photographic material, is delivered at the output end of the conveyor means.
Claim 3
Dependent Claim 277 words
Apparatus for sequentially processing a plurality of strips of film each of which ordinarily is received at the apparatus in a separate envelope and each of which ordinarily is to be returned to the same envelope after processing, the apparatus comprising: means defining a plurality of film processing stations including an initial station and a terminal station; film transport means located between said stations for conveying strips of film sequentially through said film processing stations from the initial station to the terminal station, said transport means including drive means for advancing the film; conveyor means for customer envelopes, said conveyor means being separate from said film transport means and being operable to convey an envelope from an input end of the conveyor means adjacent the initial station to an output end of the conveyor means adjacent the terminal station, said conveyor means including a plurality of envelope carriers each of which is adapted to carry a single envelope, each of said carriers being movable independently with respect to the other carriers, said conveyor means having means for presenting one carrier at a time to the input end of said conveyor means and for advancing a carrier from said input end after an envelope is furnished to the carrier and the corresponding strip of film is furnished to said film transport means, said conveyor means sequentially advancing said carriers in synchronization with advancement of strips of film by said film transport means so that a carrier for a particular envelope and the corresponding strip of film arrive substantially simultaneously at the output end of the conveyor means and at the terminal end of the film transport means, respectively.
Claim 4
Dependent Claim 277 words
Apparatus for sequentially processing a plurality of strips of film each of which ordinarily is received at the apparatus in a separate envelope and each of which ordinarily is to be returned to the same envelope after processing, the apparatus comprising: means defining a plurality of film processing stations including an initial station and a terminal station; film transport means located between said stations for conveying strips of film sequentially through said film processing stations from the initial station to the terminal station, said transport means including drive means for advancing the film; conveyor means for customer envelopes, said conveyor means being separate from said film transport means and being operable to convey an envelope from an input end of the conveyor means adjacent the initial station to an output end of the conveyor means adjacent the terminal station, said conveyor means including a plurality of envelope carriers each of which is adapted to carry a single envelope, each of said carriers being movable independently with respect to the other carriers, said conveyor means having means for presenting one carrier at a time to the input end of said conveyor means and for advancing a carrier from said input end after an envelope is furnished to the carrier and the corresponding strip of film is furnished to said film transport means, said conveyor means sequentially advancing said carriers in synchronization with advancement of strips of film by said film transport means so that a carrier for a particular envelope and the corresponding strip of film arrive substantially simultaneously at the output end of the conveyor means and at the terminal end of the film transport means, respectively.
