ABSTRACT:
The invention discloses a weight sorting system wherein a single weighing station controls a plurality of weight-range article removal stations. These removal stations are disposed downstream of the weighing station and sorting information is synchronously passed with the articles on route to discharge. The rate at which articles are selected for removal at a given station is controlled by varying the weight range for that station. The weighing system is constantly re-calibrated by employing a plurality of test weights, one for each sorting weight range, carried by the conveyor system and an electronic compensating unit.
