ABSTRACT:
A combination weighing machine produces a weight of product closely approximating a target weight by selecting a combination of lesser weights from a plurality of weigh scales and discharging the selected combination into a container or packaging machine. Each weigh scale has multiple bins for weighing and discharging multiple quantities of product respectively, and a single weight sensor. The weight of product in each bin is determined separately by delivering product to one bin at a time and measuring the change in the aggregate weight of product on the scale after each delivery. The weights determined for each bin are stored and are used in searching for and selecting an acceptable combination for discharge.
