Abstract:
Method of weighing an irregular flow of items using a dynamic system having an associated calculation unit for conversion of resulting weight signals to expressions of weight based on a relevant algorithm, said method comprising the steps of:using a weighing unit, which is operable on the basis of each of a plurality algorithms with which it is provided, to selective perform item weighing of individual items, item-group weighing of closely spaced groups of individual items, and collective-flow weighing of the flow of items; detecting the flow of items when it arrives and registering the mass distribution of the items in the flow of items, including detection of any interruptions of the flow; and using the results of said detecting step for selecting one of said plurality of algorithms for performing weight determinations and for determining further handling of the items, said weight distribution being used during weighing for switching between said item weighing, item-group weighing, and collective-flow weighing of the items of the flow of items.
