PURPOSE:To contrive quick accumulation while switching back a material by providing a route switching device in the point end of a supply conveyer so that the material can be sorted to the first/second conveyers, accumulating the material alternately by a stacker in the downstream of each conveyer, and feeding the material to the other stacker accumulated in the case of switching back the material by each stacker. CONSTITUTION:A route switching device 3 is provided in the point end of a supply conveyer 1 so that a material 2 (example, finished book) can be supplied and sorted to the first/second conveyers 4, 5. The first/second stackers 7, 8 are arranged respectively in the downstream of these conveyers 4, 5. The material is accumulated alternately by these stackers 7, 8, and in the case of switching back the material by rotating a turn table 16 in each stacker, the material is fed to the other stacker and accumulated. In this way, the table 16 can be rotated with no trouble even at a large supply speed of the material from the conveyer 1, and the material 2 supplied one after another from the conveyer 1 can be quickly accumulated while switching back the material 2. |
