Definitions

  • the present invention relates to a method of producing a packaged bale of high density filter tow material.
  • filter tow material which consists of endless cellulose 2,5-acetate filaments.
  • the individual filaments are combined after spinning into a band and then crimped in a stuffer box. Thereafter, the product is dried and then laid loosely in several meters high Grekannen.
  • the filter tow material is distributed uniformly as a layer over the cross-sectional area of the filling can by movements that change in the longitudinal and transverse directions of a laying unit. As many layers are deposited on each other until the filter tow pack has reached the desired mass and height in the filling can. Packing weights of several 100 kg are usual in this area.
  • the inserted into the Grekannen filter tow material is pressed into a filter tow bales and end packed for the purpose of transport to the filter or cigarette manufacturer.
  • the bales provided for further processing to cigarette filters weigh between 350 and 650 kg, exceptionally high density bales with weights of up to 900 kg, so-called “high-density tow bales" are available, as described for example in the document US 4,577,752 A are described.
  • the filter tow material is removed from the bale and placed on a filter rod machine, as described for example in the publication US 5,460,590 A is described, processed into filter rods.
  • the filter tow material When processing filter tow material into filter rods in a filter rod machine, the filter tow material is thickened as much as possible in a processing part. To bulge the filter tow material this is usually exploded by means of compressed air operated spreader nozzles and stretched by a system of drafting rollers, in particular with threaded or screw surfaces. After that the spreading becomes Filter tow material fed to a triacetin spray box, in which the acetate surface of the filter tow material is dissolved and tackified. In the format part of the filter rod machine, the filter tow band is gathered and compressed to the cross section of the future filter rod. The filaments stick together and form a three-dimensional spatial network structure with the filter hardness desired for further processing and for the consumers.
  • the essential quality feature for the filter or cigarette manufacturer is the homogeneity with regard to the draw resistance, since this influences the taste sensation of the smoker and the filter performance.
  • the still acceptable Switzerlandwiderstandsstreuonne are dependent on the absolute value of the draw resistance.
  • the homogeneity of the filter rods with respect to the draw resistance is determined not only by the quality of the filter tow material and the processing method in the filter rod machine, but in particular by the type of packaging of the filter tow material.
  • the type of packaging of the filter tow material is generally decisive for an undisturbed flow of the filter tow material from the filter tow bale to the filter rod machine.
  • the packaging process includes on the one hand compression of the filter tow material deposited in the filling can and, on the other hand, subsequent packaging of the compressed filter tow material into an end-packed filter tow bale.
  • the filter tow material is pressed in a baling press in the direction of the superposed layers of the filter tow material previously deposited in the filling can.
  • a baler 10, 10 'of the baler acts in the direction of the superposed layers of the filter tow material, so that the initial height of the filter tow material laid down in layers in the filling can is reduced.
  • the filter tow material does not exhibit complete elastic (reversible) behavior since the filter tow material stored in layers in the filling can does not regain its original height when over the press die 10, 10 'of the baler vertical pressing force applied to the filter tow material layers is removed again. Rather, the height at which the filter tow material grows again when the pressing force exerted on the press ram 10, 10 'of the baling press is suspended depends in particular on how long and at which pressing pressure the pressing was carried out beforehand.
  • the filter tow material compressed in the filling can it is customary to coat the still under compressive stress filter tow pack, in particular within the pressing device, with a packaging material (packaging material). After wrapping the compressed filter tow bale provided in the baler, usually the baler is opened, thus removing the compressive stress exerted on the filter tow pack.
  • a packaging material packaging material
  • the filter tow pack tends to expand after release from the baler and that perpendicular to the filter tow material layers and opposite of the baler originally exerted pressing force.
  • This elastic (relaxing) recovery proportion of the filter tow material is the lower, the longer the pressing time and the higher the pressing force during pressing of the filter tow bale in the filling can. Only the relaxing restorative component, after being released from the baler, represents the elastic restoring force which must be absorbed by the packaging material of the filter tow pack so that the bale holds together.
  • Conventional packaging materials are cardboard, which are mechanically held together by transfiguration or gluing, or plastic fabric, which are closed, for example by a Velcro.
  • the two last-mentioned types of packaging have the disadvantage that the relaxing recovery component existing after the release of the compressed bale, i. the elastic restoring force of the filter tow material, is absorbed by the packaging material. This inevitably leads to undesirable bulges on the top and bottom of the bale. Although these bulges do not interfere with the intended use of the filter tow material in the filter rod machine for the production of filter rods, but prevent safe stacking of the filter tow bales thus produced.
  • the relaxing recovery component occurring after release of the bale from the baler ie the elastic restoring force of the filter tow material
  • the elastic restoring force of the filter tow material can be reduced by correspondingly reducing the filling quantity of the bale.
  • this measure has the disadvantage that in the further processing of the filter tow material, in particular in a filter rod machine due to the reduced bale capacity relatively quickly the filter tow material of a bale is consumed and the filter rod machine with a new filter tow bales must be fitted. This leads to relatively frequent interruptions in the filter rod production, which is not accepted by the filter rod manufacturer.
  • Another measure for reducing the relaxant recovery rate of the filter tow material after release from the baler would be to increase the pressing force exerted in the baler during compression of the filter tow material.
  • this leads to quality defects in the compressed filter tow material and thus to quality defects in the filter tow material produced Cigarette filters.
  • an increased pressing force would have a negative effect on the ball outlet on the filter rod machine.
  • Another measure for reducing the relaxed rebound rate of the filter tow material after release from the baler could be to correspondingly extend the pressing time to compensate for the irreversible (ie, non-elastic) rebound rate in the filter tow material at the expense of the relaxing rebound rate to increase.
  • an extension of the pressing time inevitably reduces the press throughput, which is undesirable and unacceptable on the part of the filter tow manufacturer.
  • the present invention has the object to provide a method for producing a packed bale of high-density filter tow material, in which the failure rate of the manufactured, packaged bales is reduced and in particular less than 1%, where at the same time previously described and occurring in the prior art disadvantages are avoided.
  • the method should also be suitable for producing a filter tow bale in which the filling amount of the bale is not undershot by the filter rod manufacturers still accepted minimum, while the risk of introducing quality defects in the filter tow material at the same time Pressing minimized and the bale drain on the filter rod machine is not deteriorated.
  • a filter tow bale compressed in a baler is provided in cuboidal shape, with the compressed filter tow bale then being filled with a compressed filter tow. Bales completely enclosing, airtight packaging wrapper is packed.
  • the packaging wrapper is applied to the compressed filter tow bales such that at least 80%, preferably at least 90% and more preferably at least 95% of the packaging wrap directly abuts the high density filter tow material and thus contacts or at least less than 15 mm from the high density filter tow material.
  • the risk of a bale place after release of the packaged filter tow bale from the baler can be significantly reduced, despite the constant filling capacity of the bale.
  • the commonly used pressing process pressing force and pressing time
  • the commonly used pressing process does not have to be changed, so that for carrying out the method according to the invention can be used in the usual way in the production of high-density bales of filter tow material balers and press processes used.
  • the method of the present invention reduce the failure rate but also the risk of quality defects occurring in the filter tow material during the pressing operation, while at the same time not adversely affecting a desired bale drain on the filter rod machine desired by the cigarette or filter manufacturers.
  • Another significant advantage, which is achieved with the manufacturing method according to the invention is to be seen in the fact that the increase in the height of the filter tow bale after release from the baler according to a predetermined event sequence takes place, wherein in particular the extent of the height change is limited upwards.
  • the maximum final height of the finished packaged filter tow bale after release from the baler to a pre-definable maximum value in advance adjustable.
  • bales produced by the novel process also stack easily. Bales can thus be produced together with the maximum height of the finished bale which has been pre-determined by the method according to the invention and released from the baler.

By comparing the two recorded 2D distance measurements can be easily be determined on the actual distance between the applied packaging wrapper and the filter tow material.
  • the amount of height increase in releasing the bale from the baler must not exceed a maximum value to effectively prevent the packaging material from absorbing excessive forces resulting from the expansion of the filter tow material. Not only would this negatively affect the flatness of the top and bottom of the finished bale, but it would also result in the packaging material having to be designed to absorb these forces.
