Abstract
A plurality of pool hoppers (5) for storing a predetermined quantity of an object (W) of metering are each formed in the shape of a hollow, bottomless cylinder and are arranged side by side. A plurality of metering hoppers (7) for weighing a predetermined quantity of the object (W) supplied from the pool hoppers (5) are each formed in the shape of a hollow, bottomless cylinder and are arranged under the pool hoppers (5). A collecting device (13, 12a) for collectively storing and then discharging the object (W) supplied from the metering hoppers (7) is provided under the metering hoppers (7). A plurality of indentations (205) are arranged on the inner periphery of a barrel-type container body (201) of the metering hopper. The object (W) of metering is in point contact with the indentations (205), so that all of the object of metering is discharged from the container body. A remover (321) can be provided including a plurality of rods (321a) vertically arranged in the container body at a small distance from the inner peripheral surface of the container body. A remover rotating mechanism (22) rotates the remover (321) so that the rods (321a) move along the inner peripheral surface of t…
