PURPOSE:To attain a high-speed weighing operating by a compact structure by conducting the weightion operating with a metering hopper clamped within a precess when in a work is deopped and transferred by hopper rotating intermittently. CONSTITUTION:The metering device 10A conducts weighing and transferring operations in synchronization with the transfer by a dividing unit 4 and on the basis of a fixed sequence. When the work is charged in an upward sector of the hopper 14 in a stationary state, weighing is conducted by a balance 12 and, after the weight which the hopper 14 has before weighing is deducted from the weighed value thus obtained, the weight of the work is delivered as an electric signal. Next, when the hopper 14 is driven at an angle of 90 deg. and clamped again, the work of which weighing is completed drops in a hopper 11A with a gate and immediately later the weight of the hopper 14 is weighed and memorized. Subsequently, the charge of the work from the dividing unit 4 into the sector made upward is commenced and this operation is repeated thereafter. |
