Head and a process for filling containers with powder material

A process for filling containers with powder material, including the steps of rotating a carousel in such a way to advance at least one head mounted on the same carousel along a circular filling path extending between an infeed station and an outfeed station, placing a container on a support of said head, filling the container 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 associated with the support and operating along a substantially vertical weigh axis, wherein it comprises the step of separating the support from the weighing means.

A head for filling containers with powder material, the head being mounted on a base plate of a carousel having a horizontal disc rotatable about a vertical axis, the head comprising at least one support on which to stand at least one corresponding container, at least one dispensing element positioned in alignment with the support and serving to direct the powder material into the container, also means by which to weigh the container, associated with the support and operating along a substantially vertical weigh axis, wherein the weighing means comprise a dynamometer presenting an active portion, and the support presents a contact surface positioned to engage the active portion of the dynamometer;

• wherein a first end of the dynamometer is anchored to the frame and a second end remote from the first end coincides with the active portion;
• wherein it comprises means by which to separate the support from the weighing means comprising a first actuator actively engaging the support in such a way that the selfsame support can be moved between a first operating condition in which the contact surface and the active portion of the dynamometer are isolated one from another, and a second condition in which the contact surface engages the active portion.
