Claims:What is claimed is
1) A machine for continuous production of sachets / pouches of pre determined quantities of pulverized tobacco, the said machine comprising of
A rotating trough capable of rotating around a vertical axis and contains tobacco whose level is crucial to consistent portioning and is maintained through external means ;
A disk is provided which contains peripheral holes with an in-built Mesh that defines the predetermined volume of the tobacco portion to be filled in the sachets ;
Negative pressure, is maintained inside the disk and when the holes are immersed into the tobacco contained in the rotating trough a suitable volume of tobacco is sucked into the holes and contained therein. The disk is continuously rotated in the clockwise direction and the filled holes are presented sequentially to the dispensing station . Excess tobacco projecting beyond disk periphery is scraped for clog free dispensing.
2) The dispensing station as claimed in claim 1, essentially comprises consists of a Pressured Hot Air Blow Nozzle and the Vortex Air Flow Funnel and when a Hole matches with the funnel the said Nozzle blows pressured hot air such that the tobacco contained inside the hole is pushed into the Funnel and further into the double walled former Tube, wherein the said funnel, has been designed with holes located on its periphery and angled in such a way, that when pressurized Hot Air is blown through them from external means simultaneously, with the Air forming a helical vortex and pushing the tobacco through the former Tube ensuring that it does not get jammed with the tobacco material
3) The dispensing station of the tobacco sachets filling machine as claimed in claim 1, further comprises of a double walled former tube on top of it, is formed a flat web of film by conventional means and is pulled along by the Pulling Arrangement and Sealer Arrange means seals the web longitudinally to form a closed tube and the said Former tube conveys the tobacco portion into the open sachet waiting at the lateral sealers and sealing Arrangement creates the lateral seals thereby creating a chain of Snus sachets which are then cut and dispensed out of the machine
4) The machine for continuous production of sachets / pouches of pre determined quantities of pulverized tobacco as claimed in claim 1, wherein the tobacco material, snus, after being filled in apportioned quantities onto the sachets, possess their characteristic content of aroma, taste, flavour and tag
5) A system and method for production of sachets with powdered and pulverized materials, packed therein, the system comprising of A rotating trough capable of rotating around a vertical axis and contains tobacco whose level is crucial to consistent portioning and is maintained through external means ; A disk is provided which contains peripheral holes with an in-built Mesh that defines the predetermined volume of the tobacco portion to be filled in the sachets ; Negative pressure, is maintained inside the disk and when the holes are immersed into the tobacco contained in the rotating trough a calibrated volume of tobacco is sucked into the holes and contained therein. The disk is continuously rotated in the clockwise direction and the filled holes are presented sequentially to the dispensing station after scraping off excess tobacco.The said dispensing station essentially comprising of a Pressured Hot Air Blow Nozzle and the Vortex Air Flow Funnel and when a Hole matches with the funnel the said Nozzle blows pressured hot air such that the tobacco contained inside the hole is pushed into the Funnel and further into the double walled former Tube, wherein the said funnel, has been designed with holes located on its periphery and angled in such a way, that when pressurized Hot Air is blown through them from external means simultaneously, with the Air forming a helical vortex and pushing the tobacco through the former Tube ensuring that it does not get jammed with the tobacco material
, Description:Accordingly, it can be seen from the figures, the Snus packaging machine, comprises of a rotating trough (A1) which is rotating around a vertical axis and contains tobacco (A2) whose level is crucial to consistent portioning and is maintained through external means. The disk contains peripheral holes (A3) with an in-built Mesh (A13) that defines the volume of the tobacco portion. Vacuum (A4) is maintained inside the disk and when the holes are immersed into the tobacco (A2) contained in the rotating trough (A1) a calibrated volume of tobacco is sucked into the holes and contained therein. The disk is continuously rotated in the clockwise direction and the filled holes are presented sequentially to the dispensing station.
The dispensing station consists of a Pressured Hot Air Blow Nozzle (A12) and the Vortex Air Flow Funnel (A6). When a Hole (A3) matches with the funnel (A6), the Nozzle (A12) blows pressured hot air such that the tobacco contained inside the hole (A3) is pushed into the Funnel (A6) and further into the double walled former Tube (A15).
The Funnel (A6) has been designed with holes on the periphery located and angled such that when pressurized Hot Air is blown through them from external means simultaneously, the Air forms a helical vortex and pushes the tobacco through the former Tube. This feature ensures that the Funnel (A6) does not get jammed and is also effective in breaking lumps if any.
A flat web of film (A11) is formed into a continuous tube on top of the Former Tube (A15) through conventional means and is pulled along by the Pulling Arrangement (A10). Sealer Arrange (A8) seals the web longitudinally to form a closed tube. The Former tube (A15) conveys the tobacco portion into the open sachet waiting at the lateral sealers (A9). Sealing Arrangement (A9) creates the lateral seals thereby creating a chain of Snus sachets which are then cut and dispensed out of the machine.
The former Tube (A15) is double walled with the inner wall being made of a material with low friction coefficient, Low adhesion, cohesion properties and a good thermal insulator. The outer wall is made of Stainless Steel A304. The combination of Hot Air and double walled tube ensure that the tobacco does not coat the walls and thereby prevents Jamming.
Intermittently, Hot air at High pressures is blown through the system to ensure any residual tobacco particles stuck to the walls are cleaned out.
Through this method, it can be observed that the distance between the portioning assembly and formed sachet, has been shortened to ensured that the delivery of tobacco portions is in a straight line, thus ensuring prevention of clogging of tobacco in funnels using air flow and ensured a jam free Former tube by creating a double walled structure and using hot air to convey the Tobacco portions.
