METHOD AND APPARATUS FOR DYNAMICALLY CHECK WEIGHING

A method and an apparatus for dynamically checking the weight of objects (18a-c) which are guided across a weight-sensitive zone (14) of a weighing device (12) at an adjustable conveying rate by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual m...

Zusammenfassung:A method and an apparatus for dynamically checking the weight of objects (18a-c) which are guided across a weight-sensitive zone (14) of a weighing device (12) at an adjustable conveying rate by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E1, . . . , En) from which resultant weight values are derived in a digital evaluation unit (16) by averaging. The evaluation unit (16) includes a plurality of cascaded averaging filters (24a-e) which have different filter lengths that are varied by a common scaling factor depending on the conveying rate.
