Definitions

  • the invention relates to a conveyor arrangement for a machine of the tobacco processing industry, having a conveying device which has a plurality of conveying elements moving in a conveying direction for conveying and / or separating a fibrous product.
  • a separating device with rotating rake is known, wherein out of the circumference of the formed as a hollow pins computing tines air nozzles escape blast air jets to enhance the distribution effect of the rake tines.
  • the object of the present invention is to provide a conveyor arrangement with which an improved singulation of the product fibers can be achieved.
  • the invention achieves this object in particular in that the conveyor arrangement has at least one stationary nozzle for injecting a medium in the direction of the conveying direction in the region of the conveying elements.
  • the injected medium exerts a separation of the product fibers causing shearing forces on the entrained by the conveyor elements product.
  • the injected medium may be a gas stream, in particular from air, water vapor or a mixture thereof, or another suitable medium.
  • the medium may serve for spraying a conditioning medium in liquid or gaseous form or a mixture thereof for the product.
  • a preferred conditioning medium is water vapor.
  • Other possible conditioning media are, for example, carbon dioxide, flavorings used in the tobacco industry, sauces consisting of solids dissolved in liquid, such as sugar, humectants such as glycol, or pure gases such as nitrogen, or a mixture of these media.
  • the conveyor may serve to convey or singulate the product.
  • the term conveyor therefore also includes a separating device whose main function is the separation of the product fibers.
  • the conveying direction is in a rotating conveyor usually the circumferential direction.
  • the outlet direction of the medium emerging from the nozzle is therefore directed substantially against this circumferential direction.
  • the arrangement of the nozzle in the region of the conveying elements means that the medium emerging from the nozzle essentially hits the product entrained by the conveying elements.
  • the nozzle is arranged in the region of a free end of the conveying elements in order to possibly blow off the product from the conveying elements and thereby improve the separating effect.
  • Fixed nozzle means fixed relative to the conveyor assembly or to a surrounding the conveyor housing.
  • the invention is characterized delimited against nozzle openings in the moving conveyor elements themselves, as in the DE 100 08 961 A1 , or in itself with the conveying elements moving parts of the conveying device, such as the nozzles in the roll body of the Winnoverwalze according to the EP 0 895 721 B1 , These known nozzles are not suitable for achieving the inventive singling effect of the tobacco fibers.
  • the present invention fixed nozzle may be arranged on a housing surrounding the conveyor; however, this is not necessarily the case.
  • the application of the invention to a rotating conveyor with radially extending conveyor elements to the singulation effect by the Improve conveyor elements is not limited to rotating conveyors. It is also conceivable, for example, the application to a linear conveyor, such as a belt conveyor, with extending over the width of the belt conveyor rake. Furthermore, the application of the invention to a conveying device designed as a conditioning device for applying a conditioning medium to the product is preferred.
  • a conveyor assembly 10 comprises a closed conveyor channel 22 for conveying a tobacco product 13 entering at 24 through the opening 18 into a flow dryer 17.
  • a conveyor in the form of a rotating Winnover roller 11 is arranged in the conveyor channel 22 .
  • a conveyor in the form of a rotating Winnover roller 11 is arranged in the conveyor channel 22 .
  • Arranged on the roller body 16 are axial rows of tine-shaped radial pins 12 which form rotating rakes in order to loosen up or separate the tobacco product 13 by mechanical action.
  • the direction of rotation of the Winnover roller 11 thus forms the conveying direction F of the tobacco product 13 in the area of the Winnover roller 11.
  • the roller body 16 and / or the pins 12 may be hollow and provided with nozzle openings for applying a conditioning medium to the tobacco product, as shown in the EP 0 895 721 B1 and the DE 100 08 961 A1 is described.
  • the Winnover roller 11 is surrounded by a part of the conveyor channel 22 forming housing 20.
  • nozzles 14 are arranged, through which a gas flow 15 is blown substantially tangentially into the interior of the housing 20.
  • nozzles 14 may be formed as a nozzle bar, ie in an axially parallel nozzle channel 23 extending over the axial width of the Winnover roller 11. It can be a A plurality of nozzles 14 extending over the nozzle channel 23 or one or more elongate nozzles 14 extending over the nozzle channel 23.
  • the nozzle channel 23 is acted upon by compressed air, for example, so that the air emerging from the nozzles 14 forms an air stream 15, which is oriented approximately tangentially to the envelope or the fictitious outer circumference of the Winnover roller 11 and therefore approximately counter to the conveying direction F.
  • the air flow 15 is directed substantially in the area shown in dashed lines in Fig. 1, which may for example have an opening angle of 15 °.
  • additional guide means 21 for example baffles, may be provided at the opening of the nozzles 14; however, this is not mandatory.
  • the air flow 15 strikes the tobacco product 13 entrained, in particular, by the free ends 19 of the pins 12, and exerts this shear force, which causes loosening, singulation and homogenization of the fibers of the tobacco product 13. In this way, a more uniform drying of the tobacco product 13 in the flow dryer 17 and thereby an improved drying result can be achieved.
  • the air stream 15 sweeps along the inner wall of the housing 20 and thereby prevents deposition of tobacco material on the inner wall of the housing 20, which as a further advantage of the invention, downtime due to required cleaning of the inner wall of the housing 20 can be reduced.
