Abstract
A combination weighing apparatus includes a distribution unit, a plurality of conveying units and a plurality of weighing hoppers. At least one of the conveying units has a trough and a plurality of spiral members. The trough has an inside edge positioned below the distribution unit and an outside edge positioned above the weighing hopper. The spiral members are placed above a bottom surface of the trough with each of the spiral members defining an external peripheral surface. The spiral members are configured and arranged to be rotatably driven to convey the product material supplied from the distribution unit in a vicinity of the inside edge, along the external peripheral surfaces toward a vicinity of the outside edge. The spiral members are configured and arranged to stop movement of the product material on the external peripheral surfaces when the spiral members are not rotatably driven.
