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

摘要

Supervisory computers are individually disposed in a molding line for molding a pair of shell halves, a cartridge assembly line for assembling a cartridge shell from the pair of shell halves and other parts, a winding line for producing and winding each individual filmstrip into each individual cartridge shell, a packaging line for packaging the photo film cartridges, and those of other lines or other processes. Each supervisory computer controls process controllers of the associated line. The supervisory computers are controlled by a production information supervisory computer. Data obtained from the process controllers is sent through the line supervisory computers to the production information supervisory computer, to be stored therein.
