Abstract
A combinatorial weighing system, wherein swing plate 9 disposed substantially in the middle of the interior of a feed hopper 1 uniformly distributes objects of weighing, particularly those liable to tangle each other, in the bottom of the feed hopper without causing localized gathering of the objects, and the objects are then transferred to conveyors 5 disposed close to each other at one of their respective ends and extending in mutually opposite directions until the other ends thereof are positioned outwardly of the lateral walls of the feed hopper, whereby the objects are fed, in amounts within an allowable range of weighing, to the associated automatic weighing machines.
