Abstract
Unit for filling containers with powders, said unit comprising a measuring device envisaged for introducing a predetermined quantity of powder into a container located on a support equipment sustained by a weighing unit provided for controlling the measuring device during the filling phase of the container itself; said support equipment being provided with a shaking device which moves the container on a substantially orbital plane, in alternate directions or according to substantially orbital oscillations, in such a way as to tamp the powder inside the container itself during its filling.
Claims4
A unit for filling containers with powder, comprising:
- support equipment for supporting a container which is to be filled with powder;
- a measuring device arranged to introduce powder by gravity into the container;
- a weighing unit arranged for operating along a weighing axis of said support equipment and a control axis of said measuring device while powder is being introduced into the container during a filling phase;
- shaking means shaped and placed to make the container with respect to said weighing axis, while powder is being introduced into the container, the shaking means being arranged to move the container along a trajectory lying on a plane which is substantially perpendicular to said weighing axis;
- said shaking means being located between and arranged to operate between said support equipment and said weighing unit;
- said shaking means comprising:
- a first box element which is rigidly and kinematically connected to said weighing unit;
- said first box element having disposed internally thereof and integral therewith a fixed block which is bilaterally equipped with horizontal guides;
- a second slide element arranged to slide along said horizontal guides, with respect to said first box element, alternatingly, in a rectilinear direction;
- said second slide element being rigidly connected with said support equipment;
- return counteracting elastic means located and arranged to operate between said block and said second slide element;
- and
- vibrating means disposed between said first box element and said second slide element, for transmitting to said second slide element, in cooperation with said elastic means, vibrating motion along said horizontal guides.

- a measuring device arranged to introduce powder by gravity into the container;
- a weighing unit arranged for operating along a weighing axis of said support equipment and a control axis of said measuring device while powder is being introduced into the container during a filling phase;
- shaking means shaped and placed to make the container with respect to said weighing axis, while powder is being introduced into the container, the shaking means being arranged to move the container along a trajectory lying on a plane which is substantially perpendicular to said weighing axis;
- said shaking means being arranged to move the container in an orbital motion along a substantially circular or elliptical closed trajectory;
- said shaking means comprising:
- a support box rigidly and kinematically connected to said weighing unit;
- a kinematic chain driven by a motor and supported inside said support box;
- said kinematic chain being kinematically connected, eccentrically, to said support equipment for causing said support equipment to carry out under control of said motor, said orbital motion.
