Abstract
A machine for manufacturing pouches containing a cohesionless material, including feed means for feeding the cohesionless material to a pick-up station, a transfer drum by which the material is picked up at the pick-up station and transferred to a release station, delivery means operating at the release station and by which portions of the material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches, and a mixer located at the pick-up station for performing a mixing action on the material at the pick-up station before the material is picked up by the transfer drum.
Claims22
A machine for manufacturing pouches containing a cohesionless material, comprising:
- a feeder for feeding the cohesionless material to a pick-up station,
- a transfer drum by which the cohesionless material is picked up at the pick-up station and transferred to a release station,
- a delivery device operating at the release station and by which portions of the cohesionless material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches,
- a mixer located at the pick-up station for performing a mixing action on the cohesionless material at the pick-up station before the cohesionless material is picked up by the transfer drum;
- wherein the mixer comprises a rotating hub and one or more pins mounted on the rotating hub and arranged transversely and/or perpendicularly to a rotation axis of the rotating hub.
A machine for manufacturing pouches containing a cohesionless material, comprising:
- a feeder for feeding the cohesionless material to a pick-up station,
- a transfer drum by which the cohesionless material is picked up at the pick-up station and transferred to a release station,
- a delivery device operating at the release station and by which portions of the cohesionless material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches,
- a mixer located at the pick-up station for performing a mixing action on the cohesionless material at the pick-up station before the cohesionless material is picked up by the transfer drum, the mixer comprising a rotating hub having a rotation axis;
- wherein the transfer drum rotates about a horizontal rotation axis and wherein the rotation axis of the rotating hub lies in a vertical plane and is inclined at a mixing angle with respect to a horizontal plane.
A machine for manufacturing pouches containing a cohesionless material, comprising:
- a feeder for feeding the cohesionless material to a pick-up station,
- a transfer drum by which the cohesionless material is picked up at the pick-up station and transferred to a release station,
- a delivery device operating at the release station and by which portions of the cohesionless material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches,
- a mixer located at the pick-up station for performing a mixing action on the cohesionless material at the pick-up station before the cohesionless material is picked up by the transfer drum;
- wherein the pick-up station comprises a nip defined between a part of an outer cylindrical wall of the transfer drum and a side wall, the mixer being at least partly arranged in the nip;
- wherein the transfer drum rotates about a horizontal rotation axis and the outer cylindrical wall of the transfer drum has a bottom edge arranged at a bottom level and a top edge arranged at a top level, and
- wherein the mixer is arranged below the top level.
