Abstract
A process for producing packaged products from a film roll includes the steps of detecting whether an elongate film is defective or not, detecting whether a spool is defective or not, detecting whether an assembled cartridge is defective or not, and detecting whether a case is defective or not. Various defective products detected in these steps are removed without being fed to subsequent steps. By thus detecting various defects in the process for producing packaged products from a film roll, high-quality packaged products can efficiently be manufactured.
Claims9
A method of processing and packaging a photographic film, comprising the steps of:
- coiling a sized film cut to a predetermined length around a spool thereby to produce a film coil;
- inserting said film coil into a single-open-ended cartridge thereby to produce an assembled cartridge;
- placing said assembled cartridge into a case thereby to produce a packaged product;
- holding a part in an inspecting position in a tube, said part having a shank and a pair of large-diameter flanges on respective axially opposite ends of said shank;
- introducing an inspecting fluid into a space defined between said large-diameter flanges and an inner wall surface of said tube;
- and
- detecting a fluid pressure in said space to decide whether said large-diameter flanges are defective or not.
A system for processing and packaging a photographic film, comprising:
- a film coiling unit for coiling a sized film cut to a predetermined length around a spool thereby to produce a film coil;
- an assembling unit for inserting said film coil into a single-open-ended cartridge thereby to produce an assembled cartridge;
- an encasing unit for placing said assembled cartridge into a case thereby to produce a packaged product;
- a holder mechanism for holding a part in an inspecting position in a tube, said part having a shank and a pair of large-diameter flanges on respective axially opposite ends of said shank;
- a fluid supply mechanism for introducing an inspecting fluid into a space defined between said large-diameter flanges and an inner wall surface of said tube;
- and
- a fluid pressure detecting mechanism for detecting a fluid pressure in said space to decide whether said large-diameter flanges are defective or not.
