A predetermined number of materials 2 are placed on the main shutter 13.
When (for example, 5 volumes) are accumulated, the auxiliary shutter 12 closes again to receive the material from the second conveyor 5 as shown in FIG. 5C, while the main shutter 13 opens to accumulate the material. Is dropped on the table shutter 22 on the turntable 16. Thereafter, the same operation is repeated several times, and a predetermined amount of material (for example, 25 volumes) is accumulated on the turntable 16 (strictly, on the table shutter 22). Here, since the material 2 from the second conveyor 5 is temporarily accumulated by the auxiliary shutter 12, the main shutter 13, etc. and then dropped on the turntable 16, the distance of one drop of the material is shortened and the material is fed at high speed. It is possible to satisfactorily accumulate the incoming material 2 on the turntable without disturbing it.

A sensor (not shown) counts the number of materials delivered from the supply conveyor 1 to the second conveyor 5 during the operation of accumulating the materials on the turntable 16.
When the number of materials to be accumulated on the turntable 16 is delivered to the second conveyor 5, the path switching device 3 moves to the lower position and delivers the subsequent material to the first conveyor 4. After that, the first stacker 7 is passed through the first conveyor 4.
