Abstract
A combination weighing machine has a plurality of weigh scales for weighing quantities of product, and the scales are selectively dumped and loaded in a cyclic operation to form a package containing a number or weight of product that closely approximates a target amount. The machine includes a plurality of feeders and corresponding accumulators that are associated respectively with the scales for loading product into the scales after they are dumped. To ensure a more accurate feeding of product to a scale, a sensor is provided for detecting the pieces of product as they are loaded into the associated accumulator from a feeder, and the feeder is regulated in accordance with the pieces of product detected to control the duration of feeder operation.
