Title:

COMBINATIVE WEIGHING APPARATUS WITH TARE WEIGHT SUBTRACTING FUNCTION

Document Type and Number:

WIPO Patent Application WO/1993/023724

Kind Code:

A1

Abstract:

A combinative weighing apparatus with a tare weight subtracting function by which packaged commodities (M) can be so encased in a box selectively that the summation (SIGMAWT) of the net weights WT of the packaged commodities, which are obtained by subtracting respectively their tare weights (t) from their commodity weights (W), approximates to a target value. The apparatus is provided with many weighing sections (11) for measuring respectively the weights (W) of one or a plurality of packaged commodities (M), subtracting means (13) for calculating respectively the net weights WT by subtracting the tare weights (t) from the commodity weights (W), and a combinational weight computing means (14) for determining a combination of the weighing sections (11) so that the summation (SIGMAWT) is the nearest to the target value or the very target value.
