ABSTRACT:
A conveyor-mounted weighing apparatus is designed to eliminate any possible influence brought about by a rotational load, generated as a result of eccentric motion of at least one roller forming a part of a conveyor unit, on a weight measurement. The conveyor-mounted weighing apparatus includes a first load detector for detecting the weight of an article to be weighed then being transported by the conveyor unit and for outputting a first load signal, a second load detector for detecting a horizontally acting load imposed on the conveyor means and for outputting a second load signal, and a calculating unit for shifting a phase of the second load signal outputted from the second load detector and subtracting the phase-shifted second load signal from the first load signal outputted from the first load detector to thereby eliminate a noise component brought about by the conveyor unit.
