Patent number: 11771129Abstract: A compact cigarette manufacturing machine comprises a housing, a filling pipe, a loading element, a presser, and a push spoon. The housing encloses a material chamber comprising a bottom surface and an open end for receiving materials. The filling pipe is disposed on the housing to define a filling tip, and extends into a filling cavity in communication with the material chamber. The loading element is assembled with the housing and is operable to load the materials into the filling cavity through an opening of the bottom surface of the material chamber. The presser is assembled with the housing and is operable to press the materials loaded in the filling cavity. A push spoon slidably disposed inside the filling cavity is operable to deliver the materials in the filling cavity into a cigarette tube loaded on the filling tip.Type: GrantFiled: May 13, 2021Date of Patent: October 3, 2023Inventor: Jiandong Liu

Patent number: 7584758Abstract: A distributor or hopper is part of a cigarette production machine and serves for dressing the tobacco in the provision of a continuous tobacco strand. An integral part of a distributor is a metering system which prepares the tobacco for the production of the tobacco strand. To separate out undesirable constituents, such as foreign bodies, stalks or ribs, from the tobacco, at least one sifter (15) is provided. The latter precedes the metering system of the distributor in the working direction, in particular is arranged outside the distributor, so that sifted tobacco is introduced into the distributor.Type: GrantFiled: October 25, 2003Date of Patent: September 8, 2009Assignee: Focke & Co. (GmbH & Co. KG)Inventors: Heinz Focke, Doris Focke, legal representative, Jürgen Focke, legal representative, Ralf Barkmann, Alfred Drenguis, Frauke Illigner, Reinhard Hoppe, Tobias Jacobi, Christina Ott, Remo Schulz, Michael Wegmann

Patent number: 7335847Abstract: Method and apparatus for the separation of foreign bodies from a material flow, in particular a tobacco stream. Method is characterized in that at least a portion of the material from the material flow is conveyed into the area of a foreign-body detection device in the form of a partial material flow, whereby foreign bodies are identified by the foreign-body detection device in the partial material flow and subsequently removed from the partial material flow, whereby the partial material flow is formed by a separation step by an air flow upstream from the foreign-body detection device. Apparatus is characterized in that a material flow conveyor and a separation device arranged diagonal to the material flow conveyor are provided by which a partial material flow can be separated from the material flow. A foreign-body detection device is arranged after the separation device and after this, a foreign-body separation device.Type: GrantFiled: April 12, 2005Date of Patent: February 26, 2008Assignee: HAUNI Primary GmbHInventors: Harry Drewes, Frank Schuster

Publication number: 20070193592Abstract: The invention relates to a method and a device for obtaining the continuity of the uniformity of the structure and density of a stream of transported loose material, particularly organic plant material, and particularly tobacco material. According to the inventive method, a previously loosened material is compacted during transportation between conveyors, then, the compacted material is comminuted to a form suitable for further processing, and at least one intermediate element, preferably a bracket (5, 6), and thereby also the stream of the compacted material, is vibrated directly before the comminution process. A device according to the invention comprises at least one intermediate vibrating element, preferably this being at least one bracket (5, 6), located transversely to the direction of motion of the material.Type: ApplicationFiled: January 26, 2007Publication date: August 23, 2007Applicant: INTERNATIONAL TOBACCO MACHINERY POLAND LTD.Inventors: Wojciech Chojnacki, Arkadiusz Druzdzel

Patent number: 6782890Abstract: The distributor of a cigarette rod making machine employs a zig-zag sifter which receives a mixture of tobacco ribs and shreds from a reservoir by way of a duct or an elevator conveyor. The shreds leave the uppermost stage of the sifter and are conveyed, by a Coanda separator, into an upright gathering duct which discharges shreds for delivery onto the concave surface(s) of one or more guides serving to direct one or more streams of shreds against the underside(s) of one or more foraminous belt conveyors which advance the stream(s) past one or more trimming devices serving to remove the surplus and to thus convert each stream into a rod-like filler which is ready to be draped into a web of cigarette paper. The removed surplus is returned into the reservoir or directly into the zig-zag sifter.Type: GrantFiled: August 7, 2002Date of Patent: August 31, 2004Assignee: Hauni Maschinenbau AGInventors: Ralf Barkmann, Rolf Lindemann, Reinhard Hoppe, Bernhard Jürgens, Peter Schumacher, Manuel Hansch

Patent number: 6514014Abstract: An apparatus for receiving and transporting cigarette rejects in a cigarette manufacturing process comprises a receptacle having a receiving opening and an insertion opening for receiving rejects, a conduit having a first end and a second end and communicating with the insertion opening, and means for providing a fluid flow in the conduit for transporting the rejects. A method of collecting and transporting cigarette rejects in a cigarette manufacturing process comprises directing the rejects into a fluid stream whereby such rejects may be transported transporting the rejects in the fluid stream to a predetermined location in the cigarette manufacturing process, and separating the rejects from the fluid stream.Type: GrantFiled: September 29, 2000Date of Patent: February 4, 2003Assignee: R. J. Reynolds Tobacco CompanyInventors: Gregory Alan Holmes, Philip Andrew Deal, David Wayne Tatum

Patent number: 6170489Abstract: The carding at the periphery of a driven wheel in the distributor of a cigarette rod making machine receives tobacco particles from the lower portion of a substantially upright duct the upper portion of which can receive tobacco particles from a magazine by way of an elevator conveyor. At least the lower portion of the duct is vibrated (e.g., at an amplitude of approximately 6 mm and at a frequency of 15-25 Hertz) in directions at right angles to the horizontal rotational axis of the wheel to thus enhance the homogeneousness of the carpet of particles being transported by the carding beyond the discharge end of the lower portion of the duct.Type: GrantFiled: November 30, 1998Date of Patent: January 9, 2001Assignee: Hauni MaschinenbauInventors: Reinhard Hoppe, Rolf Lindemann, Peter Pinck
