The invention relates to a device for conveying products, in particular fruit, adapted to sort automatically these products. This device comprises a plurality of chassis (3) distributed along a conveyor (1) and each supporting a carriage (8) bearing two rollers (19) mounted on an axis (6) of this chassis so as to be able to oscillate vertically and tilt laterally. This device further comprises weighing means comprising slideways disposed in the alignment of support shoes (16, 18) with which each carriage (8) is provided, these slideways being provided with end ramps arranged such that the carriages are driven in a floating manner along the slideways. This device further comprises separation means adapted to carry out, at the loading zone of the conveyor, an ordered arrangement of the products allowing each of them to be disposed on a carriage.
