<p>A combinatorial weighing apparatus has a distribution table (10) adapted to distribute a material to be weighed and supplied thereto, a plurality of distribution supply devices (16) arranged radially around the distribution table and adapted to receive the material distributed by the distribution table, hoppers (17, 18) disposed below respective distribution supply devices and adapted to receive the material from the distribution supply devices, weight sensors annexed to said hoppers and adapted to weigh the material in respective hoppers, computing means adapted to compute the total weight of the material and to select the best combination of hoppers which provides a total weight most closely approximating preset target weight, and a hopper drive means (22) adapted to selectively drive the hoppers to make the hoppers constituting the selected best combination discharge the material therefrom. The hopper drive means is disposed so as to be surrounded by the hoppers. The apparatus has a single disc-shaped feeder base (15) common to all distribution supply devices. The distribution supply devices are arranged on the common feeder base radially at a regular interval.</p> |
