PURPOSE:To pass produced articles to the downstream process in accordance with the regular production grading even if the production grading is disordered in the upstream process, by arranging a pluraity of strage lanes having designated priorities between the upstream production line and the downstream production line. CONSTITUTION:In case of produced articles A having priorities of 1, 4, 5, 7, 3... which are taken out from an upstream production process 1, the articles A having priorities 1, 4, 5, 7 are stored in a lane 4a, but the article A having the priority 3 is stored in a stage 8a of a lane 4b. Then, the article A having the priority 10 is stored in a stage 8e of the lane 4a, and further the articles A having the priorities 9, 12 ae succesively stored in the lane 4b, following the article A having the priority 5. Thus, the poduced articles A are taken out from the lanes 4a-4e in such a way that the articles A in the forefront of the lanes or in the stage 8a having a lowest production grading are at first discharged and the articles A having the following gradings are subsequently discharged, and the articles A are taken into a downstream production process 3. |
