1. A device for feeding charges (2) of a non-homogeneous infusion material to a packaging machine (3) comprising:
a metering device for the charges of the non-homogeneous infusion material; and a transfer system (5) for the charges (2) which is positioned downstream of the metering device (4) and which feeds the charges (2) to the packaging machine (3), the transfer system (5) comprising an adjustment system (7) for the charges (2), wherein the adjustment system (7) for the charges (2) comprises a drum (14) which is rotatable about an axis (A) thereof, wherein the drum (14) comprises at least one hole (18) in which a piston (19) having an upper surface (20) with a cavity thereon is slidably movable, the cavity being dimensioned to receive the charge in its entirety, the hole (18) and the cavity in the upper surface (20) of the piston (19) defining a chamber (22) whose volume is variable between a maximum value when the piston (19) is at a first, non-operating position for receiving the charges, and a minimum value when the piston (19) is at a second, operating position for delivering the charges, wherein the transfer system (5) comprises an infeed station (6) for feeding the charges to the transfer system (5), wherein the adjustment system (7) is positioned downstream of the infeed station (6), and wherein, during transfer from the infeed station (6) to the adjustment system (7), the charges always move through spaces whose volumes are larger than the volumes occupied by the charges themselves. |
