Definitions

  • the invention relates to a device for building a continuous Tobacco rod, with a along a construction line with a suction chamber in Actively connected suction line conveyor, which is in the line inlet area a format device forming the tobacco rod into a wrapped cigarette rod passed around a press disk rotating with the suction strand conveyor is.
  • individualized and loosened tobacco fibers are usually piled up on a rod conveyor in the form of an endless conveyor belt rotating in a tobacco channel to a fiber strand which is continuously conveyed out of the strand building area and equalized before it is moved onto a belt with a circulating format belt into a format device
  • the wrapping material strip is deposited and wrapped in the format device with the wrapping material strip, for example a cigarette paper strip.
  • the wrapping material strip which is initially just arriving in the infeed area of the format device, is first shaped U-shaped around the fiber strand as it passes through the format device before it is completely wrapped around the strand and, to form a cylindrical sheath along an overlap seam, generally by gluing around the strand is closed.
  • An air-permeable fabric belt is usually used as the strand conveyor, in which tobacco particles from the strand can adhere and detach at another point due to the negative pressure applied or due to the mechanical pressure when the fiber strand is compressed, so that a proper transfer of all particles of the strand into the format device is prevented.
  • this device has a device for stripping tobacco particles, a so-called scraper, at its inlet end.
  • This device consists of a base body and has one Scraper edge, which is positioned close to the surface of the strand conveyor and wipes the tobacco particles of the strand from the strand conveyor.
  • the invention has for its object the functional reliability of such with regard to a better strand formation optimized belt deflection as well to increase their service life.
  • the pressure disk is delimited in the region of a wrap-free circumferential section by an air channel which is in flow connection on the one hand with the inner storage space of the pressure disk and on the other hand with the suction chamber.
  • the pressure plate is cleaned equally on all inner and outer dust-depositing surfaces by a permanent suction.
  • the inner surfaces are best achieved by the suction according to a further development in that the flow connection to the storage space of the pressure plate is established by air slots emerging on both sides at the peripheral edge of the pressure plate, which are expediently designed in the form of at least eight radial edge slots.
  • an even more effective dust collection and dust extraction is achieved according to a further proposal in that the thrust link block below the openings in the air duct opening in the side walls is provided with a scraper-like particle retention wedge which engages between the lower peripheral portion of the press disk and the suction line conveyor.
  • a defined dedusting zone is achieved in that the air duct, which runs essentially concentrically to the pressure plate, extends between the lower retaining wedge of the thrust block and an upper scraper connected to the thrust block and placed against the pressure plate. The dedusting of the storage space of the press disk is further facilitated in that the end faces of the press disk have openings.
  • the advantage achieved with the invention is that by a permanent Dedusting or keeping the particularly sensitive functional areas free of dust, especially the bearing points and the belt guide surface of the press disk, on the one hand, their long-term operational safety is maintained in full load operation and along with this, in the long term, secure tape guidance and thus one Increasing the belt life is guaranteed.
  • the invention is based on an embodiment shown in the drawing explained in more detail.
  • the format inlet of a cigarette rod machine is shown. It shows the discharge end of a suction strand conveyor 1 designed as an air-permeable endless conveyor belt and part of a format device 2 with a format bed 3 indicated by dash-dotted lines and an inlet finger 4.
  • the suction strand conveyor 1 rotates in the direction of arrow 6 in a tobacco channel 7 and conveys a fiber strand made of tobacco fibers (not shown) from a strand build-up zone (also not shown) for delivery to a format device 2.
  • a format belt 13 is guided in the direction of the arrow 12 and carries a strip of wrapping material 14 through the format device 2.
  • This technique of such machines is well known, so that a detailed description and description is not necessary here.
  • the suction strand conveyor 1 converges to the strand guiding surface 9 of the format bed 3 and places the tobacco strand, which has been shaken up in a strand construction zone (not shown) and leveled in the usual way, on the wrapping material strips 14 moved by the format device 2.
  • the tobacco rod is passed through the inlet cone 11 strongly compressed under the action of the suction strand conveyor 1 and deformed in accordance with the cross-sectional change of the inlet cone in the conveying direction 12 of the format belt 13 so that it can enter the strand channel partially enclosed by the strand guide surface 9 of the format bed 3.
  • the entry finger 4 is arranged as a further strand guide means with a scraper 16, which together with the strand guide surface 9 of the format bed 3 forms a strand guide that further compresses and forms the fiber strand.
  • the scraper 16 is attached to the end of the inlet finger 4 of the format device 2.
  • the underside is designed as a strand guide surface 17 and, in the installed position of the scraper, is opposite the strand guide surface 9 of the format bed 3, so that both strand guide surfaces 9 and 17 enclose a strand guide channel.
  • the strand guide surface 17 is concavely curved and aligned with a subsequent strand guide surface 18, which is formed on the underside of the inlet finger 4. This configuration of the strand guide surfaces causes the incoming tobacco rod to be deformed in a known manner into a cylindrical fiber strand while at the same time enveloping this fiber strand with the wrapping material strip 14.
  • the suction strand conveyor 1 is guided at its discharge end around a press disk 19 set in rotation by the suction strand conveyor 1, the entire discharge end and the press disk 19 being covered by side walls embodied as knife strips 21, which extend underneath along the strand guide surface 9 in Format bed 3 extend.
  • a so-called thrust link block 22 is inserted between the two knife bars 21 for guiding the suction strand conveyor 1 and is engaged with a scraper-like retaining wedge 23 at a distance in the tenths of a millimeter range in the lower gusset formed between the pressure disc 19 and the suction strand conveyor 1 against the pressure disc 19.
  • the upper side of the push-track block 22 is equipped with a scraper 24 placed against the circumferential surface of the pressure plate 19.
  • the thrust link block 22 is provided with a recess in the form of an air duct 26 which, in an approximately concentric course to the pressing disk, has its free circumferential section of the pressing disk 19 running between the upper and lower run of the suction strand conveyor 1 between the scraper 24 and the retaining wedge 23 limited.
  • the air duct 26 is connected on the one hand to the suction chamber 8 and on the other hand to the inner storage space 27 of the pressure plate 19.
  • the pressure plate 19 is provided with a total of eight radial air slots 28 emerging on both sides at its peripheral edge, so that a flow connection between the storage space 27 of the pressure plate 19 and the suction chamber 8 in the area of the air duct 26 when the air slots 28 released by the suction line conveyor 1 pass will be produced.
  • openings 29 are also provided in the end wall of the pressure plate 19 and in the two male strips 21 in the region of the lower end of the air duct 26 openings 31.
