ABSTRACT:
A quantitatively supplying apparatus is provided which includes a weighing bucket having a discharge mechanism at the bottom, a load cell for detecting the weight of said weighing bucket, and a transferring conveyor for supplying goods to said weighing bucket continuously, in which shutters are arranged in a goods drop passage leading from said transferring conveyor to said weighing bucket so as to be actuated to shut the passage at least partially. According to this apparatus, the amount of the goods dropped can be reduced by closing the shutters partially, and the accuracy with which the goods are quantitatively taken out can be heightened by accurately detecting the time at which the amount of the goods reaches a fixed weight. The apparatus also enables the goods to be quantitatively removed accurately by closing the shutters completely when the fixed weight is reached and thus stopping the acceptance of the goods by the weighing bucket.
