Patent ID: 7002082

Claim:
A combinational weighing device for weighing respective groups of objects to determine a partial combination of the groups of objects having a total weight approximating to a target combination weight, said device comprising: a first transport element transporting objects supplied; a dispersion element dispersing the objects transported by said first transport element; a supply control element controlling said first transport element on the basis of a target dispersed weight which is a target of total weight of the objects present on said dispersion element; a plurality of second transport elements transporting respective groups of objects dispersed by said dispersion element; a weight measuring element measuring respective weights of said transported groups of objects transported by said plurality of second transport elements; a detection element detecting an empty state of any second transport element and a measuring state of said combinational weighing device on the basis of said respective weights of said groups of objects measured by said weight measuring element; and a correction element determining a supply state of the objects onto said dispersion element on the basis of the result of detection of said detection element, and correcting said target dispersed weight based on the determined supply state.
