A filler head (1) carried by the carousel of a rotary powder filling machine comprises a dispensing element (3) by which a predetermined quantity of powder material is directed into a container (2) positioned on a platform assembly (7, 5) carried by a hollow frame (13); the dispensing element (3) is interlocked to a dynamometer (15) housed in the cavity (14) of the frame (13) and controllable thus during the step of filling the container (2). The platform support (5) is associated with a first actuator (18) mounted at the bottom of the frame (13) and designed to separate the selfsame support (5) from the dynamometer (15), also with a second actuator (21) by which the container (2) is caused to shake in a direction (B) that causes the powder material to settle in the container (2) during the filling operation.
1) A head for filling containers with powder material, comprising at least one support (5) on which to stand at least one corresponding container (2), at least one dispensing element (3) positioned in alignment with the support (5) and serving to direct the powder material into the container (2), also means (6) by which to weigh the container (2), associated with the support (5) and operating along a substantially vertical weigh axis (A), characterized in that it comprises means (17) by which to separate the support (5) from the weighing means (6).
11) A process for filling containers with powder material, including the steps of placing a container (2) on a support (5), filling the container (2) with the powder material at least in part, and weighing the quantity of powder material introduced into the container through the agency of weighing means (6) associated with the support (5) and operating along a substantially vertical weigh axis (A), characterized in that it comprises the step of separating the support (5) from the weighing means (6).
