Document Type and Number:
WIPO Patent Application WO/2012/131789
Kind Code:
A1
Abstract:
Provided is a combination scale capable of discharging the material being weighed so that the longitudinal direction of the material is uniformly arranged. The combination scale as in one of the embodiments of this invention is provided with the following: an aggregation conveyor apparatus (3) that transports in one direction and discharges the material being measured; a plurality of weighing conveyors (1), disposed in line with the transport direction of the aggregation conveyor apparatus (3), that supply the material being weighed to the aggregation conveyor apparatus (3) by conveying and discharging each respective unit of supplied material; a plurality of weight sensors (2) that measure the weight of the material to be weighed supplied on each weighing conveyor (1); and a control unit (5) that, on the basis of the weight value of the weight sensors (2), calculates a single discharged combination comprised of a combination of the weighing conveyors (1) wherein the combined weight of the weighed material is within a target weight, and drives the weighing conveyors (1) selected for the discharge combination to transport and discharge the weighed material on the weighing conveyor (1). The combination scale is configured so that the transport speed of the aggregation conveyor apparatus (3) is faster than that of the weighing conveyors (1).
