PURPOSE:To permit a combination weighing with a high efficiency and a high accuracy, by providing a plurality of weighing hoppers for accommodating a plurality of massive objects, a plurality of weighing devices and a plurality of memory hoppers for accommodating the weighed massive objects discharged from the weighing hoppers. CONSTITUTION:A plurality of massive objects, such as candy, fruit or vegetables, are fed from a supply device 11 and accommodated in weighing hoppers 161- 16n through a circular feeder 12, feeders 131-13n and intermediate hoppers 141- 14n, and are then weighed by weighing devices 171-17n, respectively. Pairs of memory hoppers 191, 192-192n-1, 192n are installed below the weighing hoppers 161-16n, respectively. When discharge gates 181, 182-182n-1, 182n are opened, the massive objects accommodated in the weighing hoppers 161-16n are dropped so as to be accommodated in the memory hoppers 191, 192-192n-1, 192n, respectively. This constitution makes it possible to reduce the number of the weighing devices; hence, maintenance is facilitated, and the weighing reliability is improved. |
