PURPOSE:To attain a large number of combinations with a small number of weighing meters to improve the combinational precision by moving storage hoppers provided for individual weighing hoppers so that lump materials are packed again in empty storage hoppers even from weighing hoppers, which do not correspond to these empty storage hoppers, simultaneously if plural storage hoppers of these storage hoppers are empty. CONSTITUTION:In accordance with movement of storage hoppers, the contents of storage hopper memories are shifted. Positions of storage hoppers 191-192 are shifted by one pitch, and as the result, lump materials are packed in empty storage hoppers 191 and 192 simultaneously because these storage hoppers are placed in individual supply positions from a weighing hopper 161 and a weighing hopper 162 respectively. A weighed value stored in the weighing hopper memory is transferred to a storage hopper memory 1-2 corresponding to the storage hopper 191, and a weighed value stored in the weighing hopper memory is transferred to a storage hopper memory 2-1 corresponding to the storage hopper 192. While lump materials are packed in empty storage hoppers after this movement, combinational operations are performed similarly with left storage hoppers. |
