Definitions

  • the invention relates to a device for constructing a continuous strand of the tobacco-processing industry, in particular a tobacco rod or a filter strand, with a Saugstrang employer operatively connected along a construction section with a suction chamber in the Strangeinlauf Schl a strand forming format device to a rotating with the Saugstrangadder pressure washer is led around.
  • a filter strand usually sporadic fiber materials, optionally mixed with granular materials or other materials on a circulating in a suction channel strand conveyor in the form of an endless conveyor wound into a strand, which is continuously conveyed away from the strand building area and leveled before he placed on a with a circulating format tape in a format device moving wrapping material strips or without wrapping material strips and in the format device with the wrapping material strips, eg a paper strip, is wrapped or shaped.
  • the wrapping material strip which in the inlet area of the formatting device initially just enters, is first formed into a U-shape around the strand during the passage through the format device, before it is placed all around the strand and, as a rule, by gluing around the strand to form a cylindrical shell along an overlapping seam is closed around.
  • a strand conveyor usually an air-permeable fabric tape is used, in which set by the applied negative pressure or due to a mechanical pressure in compressing the strand fibers or other strand materials in the fabric tape and replace it elsewhere, so that a proper transfer of all strand components is prevented in the format device.
  • this has at its inlet end a device for stripping strand materials, a so-called scraper or an inlet finger.
  • This consists of a base body and has a scraper edge, which is positioned close to the surface of the strand conveyor and strips the components of the strand from the strand conveyor.
  • EP 1 033 082 B1 is an apparatus for building a continuous tobacco rod, with a along a construction route with a suction chamber operatively connected Saugstrangadder known, which is guided in the Strangeinlauf Schl a tobacco rod forming a wrapped cigarette rod format device around a circulating with the Saugstrangadder pressure washer, wherein the pressure plate in the area a loop-free peripheral portion is bounded by an on the one hand with the inner storage space of the dummy block and on the other hand in fluid communication with the suction chamber in communication. This serves to increase the reliability and to achieve a better strand formation with an optimized band deflection.
  • a press disk which has on both sides at the peripheral edge of the press disk exiting air slots, which are formed in this document in the form of at least eight radial edge slots.
  • a device for building a continuous strand of the tobacco-processing industry in particular a tobacco rod or a filter strand, with a along a construction section with a suction chamber in operative connection Saugstrang dealter in the Strangeinlauf Scheme a strand forming format device to one with the Saugstrang scaleer revolving around the pressing disc, which is further developed in that a Druckluftbeaufschlagungsvorraum is arranged upstream of the dummy block in the region of the Saugstrang considerers on the side of the Saugstrang considerers, which is opposite to the side, which is used to build the strand and / or that the press plate air ducts with openings a peripheral surface of the dummy block, wherein the air ducts are arranged obliquely at an angle to the radial of the pressure disk and in or against the strand conveying direction.
  • a component of the orientation is
  • the Druck Kunststoffbuchbeetzungsvorraum is then designed so that a compressed air opening is arranged in the direction of the strand to be formed.
  • a subsequent detachment of the strand formed is simplified, since after applying compressed air less partially penetrated into the Saugstrang adapter and there entangled fibers remain in this state, but are dissolved out of the Saugstrangdecier.
  • the press disk can have air ducts with openings on a circumferential surface of the press disk, wherein the air ducts are arranged obliquely at an angle to the radial of the press disk and in or against the strand conveying direction.
  • the detachment process of the strand is also conveyed by the suction strand conveyor, with fibers that are at least partially penetrated here, in particular, being well activated in the suction belt of the suction belt conveyor can.
  • the air channels are also arranged in the strand conveying direction
  • a particularly efficient additional Ab communityluftströmung for strand material can be generated, which passes through the slot between the inlet finger and the Saugstrangier and thus does not continue to strand formation.
  • the feature at an angle to the radial of the dummy block and arranged in or against the strand conveying direction not exactly parallel or antiparallel or perpendicular to the strand conveying direction.
  • the Druck Kunststoffbuchbeaufschlagungsvortechnische is arranged in a region of the Saugstrangenseers, in which a sub-format of the formatting device is present. This avoids that the constructed and formed strand is completely detached and thus disturbed and thus the formed strand undergoes irregularities.
  • the Druck Kunststoffbeaufschlagungsvortechnisch comprises a nozzle.
  • the nozzle may be a slot nozzle having, for example, a slot which is oriented transversely or perpendicular to the suction belt conveyor or the conveying direction of the suction belt conveyor.
  • the angle of the air passages of the pressure disk in a range of 10 ° to 20 °, in particular between 14 ° and 16 °, to the radial.
  • 10 to 50 air ducts are provided in the pressure disk or preferably approximately 25 air ducts are provided in the pressure disk.
  • the air ducts may also be formed as slots whose longitudinal extent are arranged on the surface of the pressure disk substantially parallel to the axis of rotation of the pressure disk.
  • the suction chamber of the Saugstrangenseers is formed so that no suction air passes through the Saugstrangenseer on one or the upstream side of the body region of the strand on the Saugstrang elaborateer. This will prevent fibers or other strand materials from entering the suction strand conveyor at the very beginning of the construction of the fiber strand, i. hook with the suction belt.
  • the prevention of suction air passing through the suction belt conveyor on the upstream side of the body region of the strand is achieved by providing a cover in the suction belt conveyor which prevents the passage of suction air or the suction chamber is absent in that region, ie the suction chamber is shortened in total compared to conventional suction chambers, namely the area in which no Suction air should flow through the Saugstrangdecier.
  • an inlet finger for detaching the strand is provided by the Saugstrangier, which acts on the strand in the region of the dummy block, wherein the inlet finger is integrally formed and / or has a steady ramp.
  • the Saugstranger acts on the strand in the region of the dummy block, wherein the inlet finger is integrally formed and / or has a steady ramp.
  • a one-piece run-in finger with a steady ramp it has a smooth surface, i. a surface without joint seams or other irregularities, which takes place to a damming of lossy strand material, so strand material that passes through the gap between the finger and the Saugstrang adapter takes place.
  • a continuous ramp is understood to mean a ramp which exists at least in sections without an edge or without interruption. The ramp is provided above the engagement region of the inlet finger with the strand material arranged on the suction strand conveyor.
  • the Saugstrang disposeer on a supporting device which comprises a longitudinally extending in the conveying direction of the Saugstrang disposeers sword.
  • the sword is here designed as a slim or narrow counter-bearing to the suction belt of the Saugstrangenseers and acts as an abutment on the side facing away from the strand of the Saugstrang considerers.
  • the terminology in the direction away from the suction belt conveyor in particular includes a penetration of the suction belt conveyor.
  • the compressed air flow acts transversely to the radial of the pressure disk in the conveying direction of the strand material.
  • a component of the compressed air flow is formed in the conveying direction of the strand material.
  • the compressed air flow upstream of the dummy block which is formed by the Saugstrang reduceer against the Aufauerte strand material, formed in the region of the lower format flowing.
  • this compressed air flow is continuous.
  • the strand material that is lost in the step of stripping the strand material and forming the strand for forming the strand is detected by a transport air stream and carried away.
  • Fig. 1 schematically shows a view of an apparatus according to the invention for building a continuous strand of the tobacco-processing industry, in particular a tobacco rod or a filter strand.
  • a filter strand wherein the invention is explicitly not limited to the structure of a filter strand.
  • Filter materials or strand materials the in Fig. 1 not shown, but in Fig. 2 are indicated schematically as 18 and 18 'as fibers enter Fig. 1 from below into the suction shaft 10 up to Saugstrang makeuper 11 and are thrown up there or formulated more generally.
  • the suction belt conveyor 11 comprises a suction belt 25, which is formed continuously encircling and is usually a fabric belt.
  • a fabric tape is used, which in the German patent application DE 10 2010 003 287.5 is described.
  • This is a suction belt, which consists of a warp and weft threads fabric, wherein the suction belt is endless or quasi-endless, wherein the height of the warp threads of the suction belt along a weft thread is different, so that the suction belt on one side and flat on the other hand uneven.
  • the uneven side is preferably the inner side, so the side on which the strand material is not aufauert.
  • the uneven side is thus at the deflection elements, such as pulleys or a pressure plate 22 at. This serves for better detachment of a built-up strand from the suction strand conveyor in the region of the pressure disk, which will be discussed in more detail below.
  • a suction chamber 12 is provided, in which there is a negative pressure, so that there is a suction air flow through the Saugstrang considerer 11.
  • An exception to this is the upstream region of the construction section 38 or of the suction shaft 10, in particular in an initial region of the construction section 38, in which a cover 13 ensures that no or substantially no suction air through the Saugstrang considerer at this point where the cover thirteenth is arranged, passes.
  • Fig. 2 in which schematically the area B off Fig. 1 shown enlarged, explained again.
  • the cover 13 is here introduced into the suction chamber 12, so that in this area no suction air flows through the Saugstrangmer 11 and the suction belt 25. It is thus achieved that the fibers which are used for strand formation and which are transported in the suction air flow direction 17 in the suction chamber 12 from bottom to top to the suction strand conveyor 11 can not move into the suction belt 25.
  • the suction chamber 12 may be correspondingly formed such that it does not extend to the beginning region of the construction stretch 38, that is to say the region which is remote from the format device, for example comprising a sub-format 21 is arranged, ends.
  • Fig. 2 shown a further measure, which is to prevent penetration of the fibers 18 in the suction belt 25.
  • a nozzle 15 is provided, which generates an obliquely arranged air flow 16. This gives the fibers 18 an orientation which is aligned parallel to the suction belt 25.
  • results from these measures a resulting air flow 20, which ensures that fewer fibers 18 can get caught in the suction belt 25.
  • Fig. 3 schematically shows an enlarged view of the area A from Fig. 1 , For better representability because of some elements, such as pulleys, in Fig. 3 not shown. It is very schematically illustrated on the suction belt 25 strand 46 shown.
  • the strand 46 is conveyed in a conveying direction narrowing or tapering intermediate space 45 in the direction of the pressure plate 22 and detached from the inlet finger 23, which is formed in the region of the pressure plate 22 as a scraper.
  • the gap 45 results from a distance between the lower format 21 and the suction belt 25, above which the suction chamber 12 is arranged. As a result, the built-up strand 46 is compressed on the way to the dummy block 22.
  • a wrapping material strip may also be provided, which is arranged on top of the lower format on a format strip, in order to form the strand in the format device around the strand material to be wrapped.
  • the wrapping material strip and the format strip are not shown in the figures.
  • An air flow 30 serves to discharge the material which has not been detached by the scraper or inlet finger 23 and thus passes through the gap between the inlet finger 23 and the suction belt 25 resting on the pressure plate.
  • the dashed line 31 is intended to represent the fiber flow or the strand material flow passing through the gap between the inlet finger 23 and the suction belt 25 arranged around the pressure plate 22. This material or the fiber stream 31 is detected by the air flow 30. As a result, the strand material not forming a strand can be removed very efficiently.
  • the dashed line 31 thus shows the continuous losses that penetrate through the scrape gap or inlet finger gap. It makes sense that these fibers can pass and leave the space above the scraper or inlet finger 23 unhindered, otherwise they would back up to the scraper gap and build up on the edge of the scraper and tear off into the strand. This tearing of built-up fibers from the edge of the scraper into the strand leads to so-called soft spots in the strand.
  • the inlet finger 23 allows the fiber losses, unhindered to pass the space above the edge of the scraper.
  • the surface of the inlet finger which is arranged upwards to the pressure plate 22, designed as a smooth or continuous ramp, which generates a continuous opening of the free space above the inlet finger 23.
  • a scavenge air channel 39 is formed, which passes through the cover 35 and the pressure plate 22 is limited. If the fiber losses have reached the upper region of the free space above the inlet finger 23, they are detected by the air flow 30, which flows from the left into the open space or the scavenging air channel 39. The air flow 30 ruptures the fiber losses 31 with it in the suction belt conveyor and further into a disposal cabinet, not shown.
  • the inlet finger 23 is here formed in one piece, resulting in a smooth or steady ramp.
  • Fig. 4 represented very well the channels 26 of the pressure plate 22, can flow through the compressed air 44.
  • the channels are each arranged at an angle from the radial and additionally in the conveying direction 40 of the suction belt conveyor or partially in the conveying direction of the suction belt conveyor.
  • compressed air 44 is only in the in Fig. 4 shown portion of the arrow passed through the Saugstrangmer 11. From reaching the inlet finger 23 to almost to reach the arrow 44, the compressed air is switched off. The compressed air thus acts only in a rotation angle range of the pressure disk from 2 ° to 15 °.
  • a support of strand separation by means of compressed air 37 which flows through a compressed air nozzle 36 through the Saugstrangmer 11 and the suction belt 25 passes through and acts on the Aufgescherten or constructed strand provided.
  • the compressed air used is in a range of 1 to 3 bar and can preferably be adjusted via a proportional valve.
  • the compressed air 37 is preferably switched on with the start of the seam gluing of the wrapping material strip. The introduction of the compressed air 37 takes place in this embodiment in a region in which the strand is already guided from below through the lower format 21, ie in the inlet chamber.
  • FIG. 6 schematically is a section through a suction belt conveyor 11, comprising a suction belt 25, shown.
  • a side rail 41 and a side rail 42 are provided, which leads the suction belt to the side and upwards.
  • a sword 43 so a slender or narrow counter-bearing is provided substantially centrally to the suction belt 25, which extends longitudinally with the suction belt.
  • Fig. 7 is a schematic sectional view along the section C of Fig. 6 shown. It can be seen in particular the longitudinal extent of the sword 43 with the suction belt 25.
  • the air passages 26 of the pressure disk 22 may be formed as slits extending substantially parallel to the axis of rotation on the surface of the pressure plate 22 and having an opening to an interior of the pressure plate, can be fed to the pressure.
  • the overpressure can here be in the range of 1 to 5 bar.
  • the channels can be configured as conical slots. Further, the channels 26 are employed at an angle to the strand conveying direction and to the respective radial of the pressure disk.
