Method of managing information exchanged between production information supervisory computer and line supervisory computers for production of photo film cartridge

A method of managing information for production of a plurality of different types photo film cartridges, wherein a first production line produces cartridge shells and a second production line produces and winds filmstrips individually into said cartridge shells to produce said photo film cartridges, said method comprising the steps of:

• A. providing production plan data to a production information supervisory computer;
• B. controlling said first and second production lines in accordance with said production plan data through first and second line supervisory computers respectively;
• C. determining a range of cartridge ID numbers based on said production plan data in said production information supervisory computer;
• D. determining a range of film ID numbers in correspondence with said determined cartridge ID numbers in said production information supervisory computer;
• E. sending data of determined cartridge ID numbers and data of determined film ID numbers to said first and second line supervisory computers respectively;
• F. providing a cartridge ID number on each individual cartridge shell being produced in said first production line in accordance with the data of determined cartridge ID numbers;
• G. providing a film ID number on each individual filmstrip being produced in said second production line in accordance with the data of determined film ID numbers;
• H. reading cartridge ID numbers from said cartridge shells when said cartridge shells are being combined with said filmstrips in said second production line;
• and
• I. collating said read cartridge ID numbers with said determined film ID numbers in said second line supervisory computer to confirm correspondence between said read cartridge ID numbers and said determined film ID numbers.

A method of managing information for production of a plurality of different types photo film cartridges, wherein a first production line produces cartridge shells and a second production line produces and winds filmstrips individually into said cartridge shells to produce said photo film cartridges, said method comprising the steps of:

• A. providing production plan data to a production information supervisory computer;
• B. controlling said first and second production lines in accordance with said production plan data through first and second line supervisory computers respectively;
• C. determining a range of cartridge ID numbers based on said production plan data in said production information supervisory computer;
• D. supplying labels with the same range of ID numbers thereon as the range of said determined cartridge ID numbers to said second production line;
• E. attaching said labels to said cartridge shells when supplied to said second production line from said first production line;
• F. reading individual ID numbers from said labels in said second production line;
• G. printing a film ID number that coincides with one of said read ID numbers onto a side portion of one of said filmstrips being produced in said second production line;
• and
• H. before or after said one filmstrip is wound into one of said cartridge shells, collating said printed film ID number with the ID number of the label attached to said one cartridge shell.

A method of managing information for production of a plurality of different types photo film cartridges, wherein a first production line produces cartridge shells, and a second production line produces and winds filmstrips individually into said cartridge shells to produce said photo film cartridges, and wherein said filmstrips are cut from a continuous strip in said second production line, and a plurality of said continuous strips are formed by slitting a wider web of photo film, said method comprising the steps of:

• controlling said first production line by a first line supervisory computer in accordance with production order data from an information supervisory computer;
• controlling said second production line by a second line supervisory computer in accordance with production order data from said information supervisory computer;
• controlling said slitting process by a fourth supervisory computer;
• generating defect data in said fourth supervisory computer when a temporary disorder is detected in said slitting process or a defective portion is detected in one of said continuous strip, said defect data including identification data of a roll of wider web which is subjected to said slitting process at the time of said disorder, or from which said one continuous strip having said defective portion is formed, slit position data representative of an original position of said one continuous strip in a lateral direction of said wider web, and position data of said defective portion in a longitudinal direction of said one continuous strip;
• storing said defection data from said fourth supervisory computer in said production information supervisory computer;
• monitoring advanced length of said continuous strip in said second production line;
• and
• controlling said cutting process of said continuous strip based on said advanced length and said defection data such that said defective portion is cut out to be eliminated from said second line.
