<p>PURPOSE:To select and extract a proper combination of containers and to improve metering accuracy by loading an object to be metered into a metering container and performing metering/combination operation while moving the container flatly. CONSTITUTION:Objects to be metered are successively loaded into an empty container on a conveyor 2. The same number of containers as balance single substances at a balance part 9 which are stopped by a stopper 2A are placed on the balance single substance 9A simultaneously by a platen 11 and the weight signal is transmitted to a control part/operation part 15. A conveyor 3 rotates in opposite direction from the conveyor 2 and the containers are pressed against a stopper 3B. An operation part 15 calculates a combination which is heavier and closest by the combination of one to four containers and operates a selection cylinder, thus pushing out the selected containers onto conveyors 4A and 4B. In the conveyors 4A and 4B, the containers are first brought to the center, are fed to a conveyor 5 by a platen 14, and further are fed to a conveyor 6. The containers are knocked down by a knock-down stand 7 on the conveyor 6 and only the objects to be metered are sent to a chute 8.</p> |
