During the transfer into the weighing unit (K), the bottle (F) is held in the compartment (S1) of the transfer container (C), preferably by suction. An elevating comb (4) which receives the bottle extracted from the micro-feeder and which with a subsequent lowering movement deposits it on the underlying grid-shaped platform (8) of the balance (9) operates in the weighing unit. This platform is provided, for each transfer container (C), with a shallow recess (10), ideally in the form of a horizontal downward-converging truncated cone, in which the bottle centers itself under the effect of gravity, moving away from the walls of the container and from the fixed lateral guides in order not to distort the action of the balance.

Improved device for weighing systems, particularly for micro-feeders, which carry out the extraction of a bottle (F) to be weighed from a conveyor line (T) on which bottles move in single file, the extraction being performed by a container (C) with a pair of portal type compartments arranged side by side (S1-S2), so that while one compartment extracts a bottle from said line, the other compartment inserts the bottle extracted in the preceding, cycle into the same line, characterized in that the improved device comprises an elevator comb (4) located laterally with respect to said conveyor line, normally coplanar with said line, and located above a complementary grid-shaped platform (8) connected to sensors of a weighing balance (9), the whole being done in such a way that the bottle to be weighed is initially transferred by container (C) to said comb which is subsequently lowered to deposit said bottle on the grid-shaped platform of the balance, without transmitting any appreciable vibration to the balance, in a similar way to what happens in the subsequent phases of the cycle when, on completion of weighing, the bottle is raised from the grid-shaped platform of the balance by the elevator comb which takes over the support of the bottle before it is traversed by container (C) and replaced on the conveyor line of the micro-feeder.
