Definitions

  • the invention relates to a device for applying a glue trace to a wrapping strip of a rod-shaped product of the tobacco-processing industry having the features of the preamble of claim 1.
  • the wrapping strip generally serves to fix the shape of the rod-shaped products, which are e.g. Precursors, such as filter rods or tobacco, or even finished products, such. Cigarettes, cigarillos, with or without filters.
  • Precursors such as filter rods or tobacco
  • finished products such as Cigarettes, cigarillos, with or without filters.
  • the wrapping strip is first deflected and laid on an endless conveyor belt in a continuous manufacturing process. Subsequently, a filter material of loose filter material fibers, filter segments or a strand of not yet fixed tobacco fibers is placed on the wrapping strip. The wrapping strip is then guided with the overlying strand through a shaping section in which the wrapping strip is turned up at the side of the strand and provided on one edge side with a thin glue trace. Subsequently, the wrapping strip is further wrapped around the strand until the edges of the wrapping strip overlap. The edge sides of the wrapping strip are then glued together by exerting a small pressure force on the glue track, so that the strand is then fixed in shape in cross section through the wrapping strip.
  • the glue trace in the form of glue dots with a be applied to certain distance, which is the case, for example, in a sticking of the filter segments in a Unterbeleimung.
  • the glue spots in this case are applied in the middle to the wrapping strip at a location well before the wrapping strip is turned over, and serve to pre-fix the filter segments to the wrapping strip.
  • the applied glue volume in this case may e.g. be controlled by a speed control of the gear pump.
  • a disadvantage of the solution described above is that the glue, due to the friction on the inner wall of the nozzle, is distributed unevenly out of the nozzle over the cross section. As a result, the glue outlet speed is significantly greater in the center of the nozzle opening than in the edge section of the nozzle opening due to the prevailing laminar flow and has a parabolic course over the nozzle opening Cross-section on. Since a certain minimum amount of glue across the entire width of the glue trace must be applied to create a glue track with a certain width, and the glue exit speed in the center of the nozzle opening due to the above-described problem is necessarily higher than in the edge zone, the glue in the Center of the nozzle opening compared to the actual required amount of glue per area applied in an excessive amount.
  • the period of time in which the wrapping strip is guided past the edge portions of the nozzle opening directed parallel to the transporting direction, due to the circular shape of the nozzle outlet, is significantly less than the period in which the wrapping strip is guided past the central portion of the outlet opening.
  • both circumstances result in significantly more glue being applied in the middle of the glue line than in the edge sections.
  • the glue in the middle of the outlet opening passes through the porous coating strip to a greater extent, without contributing to the bonding of the edges of the wrapping strip.
  • This effect is also known as glue punch.
  • the glue penetration is proportional to the porosity of the wrapping strip and, in addition to an undesirable possible change in the taste of the products to an undesirable contamination of the entire device and the subsequent products.
  • the glue penetration will increase the adhesive power further reduced in addition to the reduction of the bond strength due to the different distribution.
  • the filter material is highly compressed in the strand production and is crosslinked in shape only by the drying of the applied acetate, the filter material still exerts a relatively high restoring force at the time of bonding. For this reason, a hot glue seam with a high immediately effective adhesive force is applied to the wrapping strip.
  • the hot glue is not resistant to aging, and the filters are not always processed in a timely manner, or the adhesive can then be reheated for other purposes, the gluing of the edges can optionally be done by a second, also referred to as support seam, parallel to the hot glue seam extending Kaltleimnaht be stabilized.
  • the wrapping strip for curing the cold glue seam is guided past a heating bar with the smallest possible distance, whereas in filter machines only the hot glue seam is cured by a cooling bar during the production process.
  • the optional cold glue seam provided in the filter machine hardens without an external energy supply in contrast to the cigarette production. In principle, the excess glue mass can adversely affect both the curing process and the guidance of the wrapping strip as such.
  • the cold glue track and the hot glue track are applied in parallel on a very narrow edge portion of the wrapper strip of the filter. Due to the very narrow marginal strip, the glue traces must be applied with as small a shape deviation as possible from a given course and a predetermined width.
  • the invention has for its object to provide a generic device with which a glue line with a glue amount of (3g to 45g) / 600m with the highest possible adhesive force on a moving at transport speeds of at least 100m / min wrapping strip can be applied.
  • the nozzle has a rectangular cross-section outlet opening, which is aligned with the longer edge side at an angle of 80-100 degrees, preferably perpendicular, to the direction of movement of the wrapping strip, and the shorter edge side of the outlet opening a Length of 0.1 to 0.5 mm, preferably from 0.2 to 0.5 mm and particularly preferably of 0.4 mm in the transport direction of the wrapping strip has.
  • the so-called glue penetration through the wrapping strip can be reduced so that the amount of glue applied is used to a significantly greater extent for the bonding of the edges and the bond is thus stronger with the same amount of glue.
  • the effect of more uniform glue application is favored by the exit surface of the outlet opening is reduced by the proposed design compared to the previously used nozzles.
  • the edges of the wrapping strip to bond much stronger together, which in particular during the manufacture of the filter strand, the hot glue track can be omitted.
  • rectangular is intended to mean all cross-sectional shapes with rounded corners and / or not parallel aligned opposite edge sides, as far as the cross-sectional shape has two different lengths major axes and can be approximated a rectangular shape.
  • the cross-sectional shape can also be modified to a bone shape or an extreme oval with an elongated shape whose major axes correspond to the respective larger length then the edge side with the greater length of the rectangular shape and are aligned corresponding to the wrapping strip moved past.
  • the longer edge side of the outlet opening has a length of 0.6 to 2.0 mm, preferably from 0.8 to 1.6 mm.
  • the proposed dimensioning of the outlet opening, in conjunction with the proposed dimensioning of the shorter edge side, creates an opening cross-sectional area through which the favorable flow conditions described above with the described advantages can be realized in a particularly simple manner.
  • a particularly wide and uniform glue trace and thus a firm bonding of the edges of the wrapping strip can be achieved if the longer edge side of the outlet opening has a length of about 1.6 mm and the shorter edge side of the outlet opening has a length of about 0.4 mm having.
  • an uninterrupted glue trace with a width in relation to the glue amount of approximately 1.6 mm could be realized, which with a conventional nozzle with a circular outlet opening of 1.6 mm diameter only by a considerable increase in the amount of glue applied Length of the wrapping strip was to be realized.
  • the outlet opening having a cross-sectional area of 0.2 to 0.8 mm 2 , preferably 0.4 to 0.7 mm 2 .
  • the proposed cross-sectional area corresponds to approximately one third of the cross-sectional area of the round comparison nozzle with a circular outlet opening with a diameter of 1.6 mm.
  • the exit velocity is thereby tripled at an identical exit amount of glue per length of the wrapper strip.
  • the proposed exit surface has been found to be particularly advantageous in terms of the adhesive force to be achieved, with a particularly uniform glue trace with a low glue penetration and a high adhesive force in this case can be achieved if the glue in a glue content of (10 to 30g) / related is applied to a length of the wrapping strip of 600m with filters and a glue amount of about 3-8g / (600m) with cigarettes.
  • a conveyor is provided, with which the glue is conveyed continuously from a glue reservoir to the nozzle, and that the conveyor, the glue with a pressure of max. 4 bar promotes.
  • the proposed conveyor and the proposed delivery pressure of the glue can be optimally applied in coordination with the proposed shape and size of the outlet opening.
  • the outlet opening may be covered by a sieve.
  • the sieve is formed by a plurality of smaller outlet openings, which are preferably arranged regularly and, for example, may also be round. Due to the large number of outlet openings, the emerging glue stream can be further homogenized. In this case, the available free flow area is limited to the sum of the area of the smaller flow openings, which then form in total, for example, a comparable free flow area.
  • the outlet opening is initially enlarged in the cross-sectional area and then reduced accordingly by the sieve again.
  • the smaller outlet openings of the screen are thus arranged on a rectangular base, through which the same positive effect can be achieved to increase the bond strength.
  • the nozzle is angularly adjustable with respect to its longitudinal axis.
  • the outlet opening can be rotated in different positions to the wrapping strip. Since the outlet opening is formed rectangular according to the proposal according to the invention, results from the rotation of the outlet opening a different glue track width, since the projected width of the outlet opening is changed in the direction of movement of the wrapping strip.
  • a drive device is provided for adjusting the nozzle.
  • the drive device may be, for example, an electromotive, pneumatic or hydraulic drive device, by means of which the adjustment process can be simplified in itself and in particular can be made with increased accuracy.
  • the adjustment of the angular orientation of the nozzle about its longitudinal axis for example, for a quick format change of the parent system makes sense, in which the entire system is converted to produce products of other lengths or other diameters. It can be changed by a controlled rotation of the nozzle about its longitudinal axis as the decisive size, the glue track width, the amount of glue can then be controlled by a control of the conveyor.
  • a device for gluing a moving wrapping strip 4 with a nozzle 8 of an applicator 1 can be seen.
  • the wrapping strip 4 is, for example, a strand of endless cigarette paper or filter paper, which is supplied in a known manner from below and is placed over a deflection device 5 on a likewise endless format strip 7.
  • an endless tobacco or filter material fiber strand 3 is placed on top of the deflected wrapping strip 4 from above.
  • the format strip 7 is guided over a second deflection device 6 on a format background and serves to transport the wrapping strip 4 with the laid tobacco or filter material fiber strand 3 during the further movement on the format reason.
  • the format reason itself is arranged including not shown thereon Cover strips provided with a shape through which a total shaping channel is formed, through which the wrapping strip 4 is wrapped around the tobacco or Filtermaterialfaserstrang 3 during the transport movement and then glued together for fixing to the superimposed edges. Furthermore, a second application device 12 is directed with a nozzle 11 in the lower run on the wrapping strip 4, via which, for example, a broken glue trace with regularly spaced spaced glue dots or a continuous glue trace is applied to the wrapping strip 4 for adhering filter segments.
  • the format strip 7 transports the wrapping strip 4 with the resting tobacco or filter material strand 3 past the fixed nozzle 8 at a strand speed of 100 to more than 600 m / min.
  • the outlet opening of the nozzle 8 is at a constant distance of 0.1-10 mm, preferably 0.2-5 mm, and particularly preferably 1.0-2.5 mm, to the wrapping strip 4.
  • the glue trace is applied practically contacting.
  • the glue trace can also be applied in contact with the filter production.
  • the first application device 1 further comprises a gear pump, not illustrated, which supplies the nozzle 8 with a cold glue mass with a pressure of max. 4 bar feeds.
  • the nozzle 8 can be seen in an enlarged view in view of a provided on the front surface outlet opening 2 of a flow channel of the nozzle 8.
  • the cold glue flows through the flow channel of the nozzle 8 and exits through the outlet opening 2 from the nozzle 8 and is thereby applied to the pasted wrapping strip 4.
  • the outlet opening 2 is rectangular in shape and in the in the representation of Fig. 1 oriented position to the wrapping strip 4, that the longer edge side 9 is aligned perpendicular to the direction of movement of the wrapping strip 4.
  • one of the length of the longer edge side 9 corresponding glue track width of approximately 1.6 mm with a much more uniform distribution of the glue across the width of the glue line, whereby a round nozzle can be replaced with 1.6 mm. If other glue track widths are to be realized, the length B of the longer edge side 9 must be adapted accordingly, wherein the width of the glue line can be determined by the design of the length B considerably more accurate.
  • the glue trace can be applied much more accurately in width according to a predetermined glue track width and with a much more accurate course.
  • the adhesive power of the glue trace can be increased with the same amount of glue and, at the same time, the glue penetration to be avoided can be reduced.
  • Fig. 3 is the final bond strength KK one with a conventional nozzle 8 with a circular cross-section outlet opening with a diameter of 1.6 mm applied glue line through the curve II and the end bond KK one with a nozzle 8 according to the invention with a rectangular outlet opening according to the Presentation in the Fig. 2 represented by the curve I.
  • the curves I and II show the final bonding strengths KK produced after removal of the products from the device for different strand speeds S of 100 m / min up to 600 m / min.
  • the dashed line III shows the initial bond strength, which must be at least applied by the glue trace during the passage of the products through the device in order to keep the strand closed.
  • the nozzle 8 can also be made adjustable about its longitudinal axis S, so that the orientation of the outlet opening 2 can be changed relative to the wrapping strip 4 moved past. So it is e.g. conceivable to turn the nozzle 8 so far that the longer edge side 9 at an angle of e.g. 30 to 60 degrees to the direction of movement of the wrapping strip 4 is aligned. As a result, the width of the applied glue track can be changed.
  • a width of the glue track of half the length B of the longer edge side 9. can be realized very easily.
