<p>A machine (1) for filling bottles (2) fed in succession with intermittent motion along a preset path (3) with powdered material comprises a filling station (4) with at least one pair of powder dosing disks (5), located above the bottle (2) path (3), rotating intermittently in one direction about their geometric axes (10), and having radial cavities (7) and pistons (8) which together form spaces for receiving, transferring and unloading dosed quantities of powders into the bottles (2). The pistons (8) move axially in the cavities (7) to vary the powder dosing spaces. The machine (1) also comprises drive means (6, 9) for the dosing disks (5), adjustement means (20, 11, 12) for the relative dosing spaces and a remote control mechanism (13, 14) for the adjustment means (20, 11, 12), located together with the drive means (6, 9) on the same side of the pair of dosing disks (5). An epicyclic gear train (13, 14, 16, 17), for producing an angular offset between each dosing disk (5) and a relative disk (20) for volumetric adjustment of the powders which is connected to it, is an integral part of the present invention.</p> |
