Patent number: 8893723Abstract: Method and device for removing foreign bodies from a first tobacco stream that is conveyed via an air flow in a region of a first foreign body detection device. Method includes detecting, with a first foreign body detection device, the foreign bodies in the first tobacco stream based on at least one property, and removing, with a jet of compressed air, the foreign bodies from the first tobacco stream. In this manner, a foreign body freed tobacco stream and a second tobacco stream including tobacco particles and the foreign bodies entrained by the jet of compressed air are formed. Method also includes at least one of: accelerating the second stream at a distance from the first tobacco stream; and detecting, with a second foreign body detector, foreign bodies in the second stream based on at least one property and removing the detected foreign bodies with a second jet of compressed air.Type: GrantFiled: January 7, 2010Date of Patent: November 25, 2014Assignee: Hauni Maschinenbau AGInventors: Matthias Jahnke, Harry Drewes, Torsten Grigutsch, Hans Dierken, David Felts, Jeroen Erinkveld, Diederick van Klaarbergen

Patent number: 7992574Abstract: The invention concerns an apparatus for cutting at least one continuously conveyed rod into rod-shaped articles of variable length, in particular cigarettes, filters or the like, including a cutting device, a counter-support and displacing devices for the cutting device and the counter-support for varying the cut length of the articles, which is characterized in that the displacing devices for the cutting device and the counter-support are coupled together to make a functional connection. Furthermore, the invention concerns a corresponding method which is characterized in that, to alter the length of the articles to be cut off the rod, only one component is displaced, namely optionally the cutting device or the counter-support, and the other component is automatically displaced with it as a function of the displaced component.Type: GrantFiled: September 20, 2005Date of Patent: August 9, 2011Assignee: Hauni Maschinenbau AGInventors: Matthias Jahnke, Konrad Popp, Detlef Ahlborn

Patent number: 7281621Abstract: A transfer apparatus is provided for the transfer of rod-shaped articles, in particular filter rods, from a conveying apparatus for transverse axial conveying of the articles to a conveying apparatus for longitudinal axial conveying of the articles or vice versa. The directions of transport of the conveying apparatuses running transversely to each other. The transfer apparatus includes a rotatably driveable conveyor with at least one receptacle. Each receptacle is adapted to take at least one article off the conveying apparatus for transverse axial conveying of the articles and discharging the or each received article to the conveying apparatus for longitudinal axial conveying or vice versa. Each receptacle traverses a variable running circle. Several receptacles are evenly distributed over the circumference of the conveyor, all the receptacles being radially displaceable synchronously during operation of the apparatus.Type: GrantFiled: September 14, 2005Date of Patent: October 16, 2007Assignee: Hauni Maschinenbau AGInventors: Matthias Jahnke, Konrad Popp
