PURPOSE:To facilitate the extraction of lot products at a fixed ratio by storing the number of stored buckets for each lot determined from the expected number of total products as the stored schedule and extracting the products from the right end and its left side simultaneously when extracting them. CONSTITUTION:Products are produced and stocked at a fixed ratio to the number of total products for each lot, e.g., 1:2:4:2:1, and for shipping, five lots are mixed and shipped. Next, for extracting, a control circuit directs the extraction of actual buckets to an outlet traverser control circuit, and an outlet traverser stores actual buckets in a bucket extraction line 20. In this case, when the outlet traverser extracts buckets from actual bucket lines consisting of six lines, buckets are first extracted from actual bucket lines 14, 15 and next from actual bucket lines 15, 16 by shifting one line, and these actions are repeated for extraction. Accordingly, actual products can be stored in the actual bucket extraction line 20 at the bucket ratio of 1:2:4:2:1.
