Circular filling machine particularly for slender and elongated products
A circular filling machine particularly for slender and elongated products, comprising a carousel assembly which supports a plurality of filling funnels which can be inserted in corresponding containers supported by transfer pans, the filling machine further comprising vibration elements for the funnels, vibration elements for the containers, and a tamping assembly for the insertion and final packing of the product in the containers.
1. A circular filling machine particularly for slender and elongated products, comprising
a carousel assembly which supports a plurality of filling funnels which can be inserted in corresponding containers supported by transfer pans,
a vibration unit for said funnels,
a vibration assembly for said transfer pans supporting said containers, and
a tamping assembly for the insertion and final packing of the product in said containers, wherein said tamping assembly comprises a plurality of tamping elements which are connected to a stem which is guided slidingly between pairs of rollers defined by carriages, said carriages being connected to one another in a chain and said carriages running along pairs of pulleys which are arranged above a tray, for containing the product to be dosed, of said carousel, said carriages connected in a chain having at least one portion of the extent of their movement which coincides with the movement of said funnels.
2. The circular filling machine according to claim 1 , wherein said vibration unit for said funnels comprise a cam with which rollers of each of the funnels engage, said rollers being connected by means of brackets to the funnels.
3. The circular filling machine according to claim 2 , further comprising a support which is associated with the tray of said carousel to define a guide for a translational motion of said bracket.
4. The circular filling machine according to claim 1 , wherein said vibration assembly for said transfer pans supporting the containers comprise a cam follower roller, which is associated with each pan and can engage a corresponding sector connected to said vibration assembly.
5. The circular filling machine according to claim 1 , wherein said vibration unit for the funnels and said vibration assembly for the containers are independent of each other.
6. The circular filling machine according to claim 1 , further comprising, on said stem, a tamping element lifting roller which can engage a cam track for the translational motion of said tamping element in a vertical direction.
