Definitions

  • the invention relates to a format part of a strand machine of the tobacco-processing industry, with a strangfizhrenden and / or strand-forming scraper and a strand-forming and / or strand-guiding molding, wherein the cross section of both the scraper and the molding in the longitudinal direction, ie in the conveying direction T of the strand-like fiber material , changed on the fiber material side facing.
  • the invention relates to a format device of a strand machine of the tobacco-processing industry.
  • a format device usually comprises, in addition to the format part, a format bed which, together with the format part, forms a channel for the strand of fiber material.
  • the fiber material is jerked on or on a suction belt conveyor, such that the fiber material is transported hanging on a suction belt of the suction belt conveyor.
  • a (quasi endless) strand of fiber material with a substantially rectangular cross-section and a cross-sectional area X.
  • the format part with the scraper first ensures that the strand of fiber material is completely stripped off the suction belt, so that all fiber particles of the strand are conveyed into the downstream in the conveying direction T molding.
  • the format part and in particular of the molded part By means of the format part and in particular of the molded part, the strand having the originally substantially rectangular cross-section and the cross-sectional area X - in conjunction with a channel forming a format bed or the like - into a strand having a substantially round cross-section and a cross-sectional area Y ⁇ X transformed. Accordingly, the format parts and format devices are basically in direct contact with the fiber materials.
  • Known format parts such as those in the DE 102 02 847 A1 Therefore, comprise a strand-guiding and / or strand-forming scraper and a strand-forming and / or strand-guiding molding.
  • the cross section of both the scraper part and the molded part changes in the longitudinal direction of the format part.
  • the cross section of the format part in the conveying direction T of the strand-shaped fibrous material changes with respect to the contour and the circumference.
  • the contour change takes place, in particular in the doctoring part, based on the length of the doctoring part, predominantly in the last third thereof, whereby the reduction of the cross section in the doctoring part takes place abruptly.
  • This disadvantageous shaping of the scraper part on the one hand leads to a high load on the fiber material.
  • the unfavorable change in the contour of the surface of the scraper part facing the fibrous material or of the unfavorable cross-sectional profile a so-called displacement of the fiber material occurs.
  • the known format part is designed in several parts. This means that there is a connecting joint between the scraper part, which is detachably fastened to the molded part, and the molded part.
  • This joint forms a joint which impedes the continuous flow of fiber material during cross-sectional forming.
  • This also leads to a shift of the fiber material with disadvantages for the product quality.
  • the example of cigarette manufacturing lead to the mentioned disadvantages, for example to head loss.
  • the known format parts are exposed by the described shape of the format part as a whole and the scraper part in particular a high wear.
  • the invention is therefore an object of the invention to provide a wear-resistant format part, which ensures a gentle transformation of a strand of fiber material.
  • the cross-sectional change of the scraper continuously extends from the front edge of the scraper to the rear edge of the scraper.
  • Idealome run the straight lines connecting the front edge and the rear edge in plan view in parallel.
  • a preferred embodiment of the invention is characterized in that the cross-sectional change over the entire length of the format part, namely the scraper part and the molded part, linear. This ensures a particularly uniform and gentle deformation or cross-sectional change of the fiber material strand.
  • the ratio of the lengths of scraper part to molded part is at least 0.5.
  • the length refers to the respective forming section of scraper part and molded part, on which an active deformation and / or guidance of the strand of fiber material takes place.
  • the transition region between the scraper part and the molded part is barrier-free. This means that neither a recess nor an elevation is formed between the scraper part and the molded part. In other words, a flat and planar transition is created.
  • the format part is integrally formed.
  • scraper part and molded part are integrally formed as a one-piece unit.
  • a completely barrier-free transition between the individual sections is achieved in a particularly simple and precise manner.
  • a particularly simple and consistent channel formation can be achieved.
  • both the scraper part and the molded part are provided with a hemispherical coating at least on the side facing the strand.
  • the format part has a particularly slippery and abrasion-resistant surface in the areas with which it comes in contact or comes into contact with the fiber material.
  • the diameters of the hemispheres can be within a coating and / or coating to Vary coating. This type of coating ensures low-friction transport of the fiber material through or along the format part.
  • the coating consists of a structured hard chrome layer or a titanium-aluminum-oxide ceramic layer.
  • a particularly wear-resistant surface is created, which allows a long service life.
  • the coating has a roughness greater than 5 microns. This means that the coating or its surface is expressly not smooth. Preferably, the coating has a roughness between 5 microns and 14 microns. With such a surface structure, which has a significant influence on the product quality, the friction can be further reduced.
  • An embodiment of the invention is characterized in that the thickness of the coating is less than 0.3 mm. Preferably, the thickness of the coating is between 0.1mm and 0.2mm. This provides a precise and highly wear-resistant surface.
  • the invention will be explained with reference to a format part, for example a so-called scraper finger, in a cigarette rod machine.

  • the cross-sectional change of the scraper part 13, ie the deformation of the cross-sectionally initially rectangular strand of fiber material is distributed in a round or cylindrical strand Fiber material, over a longer distance, so that the load on the strand is reduced.
  • the change in cross section over the entire length of the format part 12, namely the scraper part 13 and the molded part 13 is linear. This means that the strand of fiber material is uniformly and linearly changed from the entry into the format part 12 to the exit from the format part 12 over the entire length of the strand guide surface 16 from large and rectangular to small and round.
  • the scraper part 13 can be made significantly shorter than the molded part 14.
  • the ratio of the lengths of scraper part 13 to molded part 14 may be 0.25.
  • the ratio of the lengths of scraper part 13 to molded part 14 is preferably at least 0.5.
