Patent attributes
The device for dynamically weighing postal items (P) comprises a plate (1) floatingly mounted on a weight sensor, and a conveyor belt mounted on the plate to move the postal items in a longitudinal direction (D) of the conveyor. The conveyor has two parallel conveyor belts (2C, 3C) which extend along the conveyor direction between a conveyor inlet (E) and a conveyor outlet (S), and between which the postal items are pinched and moved in series on edge. The two conveyors belts are engaged on a pair of first elastically deformable finned wheels (2A, 3A) disposed at the inlet (E) of the conveyor and being aligned perpendicularly to the longitudinal direction, and on a pair of second elastically deformable finned wheels (2B, 3B) disposed at the outlet (S) of the conveyor and being aligned perpendicularly to the longitudinal direction, and the operation of the weight sensor is based on the electromagnetic principle of flux compensation.
