<p>PURPOSE:To prevent a processing having a low priority value from being excessively delayed by grouping articles to be processed stored in a buffer in conformity with given priority values and taking out them from the buffer for successive processings. CONSTITUTION:In a process 1, a plurality of articles conveyed in are stored in a buffer. In a process 2, the articles stored in the buffer are grouped in conformity with ratios (for example, a ratio ot A to B is 2:3) priority values provided for respective types of the articles. In a process 3, the articles which have been grouped are taken out from the buffer which are then processed as follows. For example, assumed the kinds of the articles to be A, B and priority values thereof to be PA, PB, they are grouped such that a ratio of the construction of the articles A and B is PA:PB as possible as, and those groups are processed in succession. Thus, there is eliminated a possibility that an article of a low priority value is left over an delayed in its processing.</p> |
