Definitions

  • the invention relates to a method of moistening bundles of flexible material, in particular bundles of tobacco leaves, by placing each bundle at the base thereof into a clamping means and passage the same through a space into which there is atomized a liquid, such as water.
  • Such a method is known from DE-A-2 147 224.
  • the bundles are placed in upright position into a clamping means and are passed through a space into which water is sprayed from above and from below onto the bundles.
  • This treatment is effected because a certain moisture content is necessary in order to avoid pulverisation in particular during the subsequent working up thereof.
  • Tobacco leaves may have a very different structure and accordingly it is of utmost importance that the proper amount of moisture is applied in such a manner that distribution thereof will be uniform and in the proper amount everywhere.
  • Tobacco leaves are supplied in bundles the stalk ends of which are tied together by means of a tobacco leave or rush. Previously it was known to remove this tie and to moisten the leaves separated from each other within a drum. This method is complicated and time consuming.
  • the object of the invention is to provide a method and an apparatus not subject to said drawbacks.
  • This effect may yet be enhanced if during the passage through the moistening space the direction of rotation is altered one or more times. Upon alteration of the direction of rotation the bundle of leaves will assume each time a limply drooping position before being fanned out again when the rotation in the opposite direction is restarted.
  • the air within the moistening space is kept yet also in turbulent motion, it being preferred to impart this turbulent motion to the air by means of air jets for atomizing the liquid.
  • the invention furthermore relates to an apparatus for moistening bundles of flexible material, in particular bundles of tobacco leaves, comprising an endless conveyor guide and an endless conveyor chain guided therein and provided with a plurality of mutually spaced clamping or hold means, each clamping or hold means being adapted for clamping or holding, respectively, one bundle to be treated, said chain passing consecutively through an insert station, a moistening space and a discharge station.
  • an apparatus is known from DE-A-2 147 224 mentioned before.
  • the clamping or holding means hold the bundles in an upright position. The leaves of the bundle then will fall down in different directions and stick together in wet condition, because they are moved through the moisting space in a non changing condition with the leaves overlapping each other which inhibits uniform moistening.
  • this is improved in that each clamping or holding means is fastened to said chain in a downwardly hanging position and operable to be rotated about its vertical central axis.
  • the rotary movement of the clamping or holding means may be brought about in several ways.
  • this may be realized in a simple manner by suspending said clamping means in a freely rotatable manner and providing the same with a cylindrically curved surface coaxially with respect to the axis of rotation and by providing an endless belt operative to be driven and extending parallel to the direction of conveyance in said moistening space, said belt being operable to engage said cylindrically curved surface.
  • the holding or clamping means upon entering the moistening space the holding or clamping means will immediately engage a driven belt, whereby said clamping or holding means are set in rotation causing the leaves to fan out.
  • the bundles may be rotated consecutively in the one direction and after a short interruption accompanied by a stand still of the leaves in the other direction.
  • clamping means of a type that automatically closes upon insertion of a bundle. In principle several constructions are conceivable for attaining such object. At the location of the discharge station there may then be provided means causing the release of the clamping means.
  • the atomizers may be provided in the bottom part and the top part of the moistening space, it being preferred in accordance with the invention to make provisions that the atomizers in the bottom part of the moistening space are adjustable in vertical sense in order to adapt the position there of to the size of the leaves.
  • the clamping or holding means are rotatably supported in sealing plates connected to each other to form a chain, said sealing plates being accommodated between the driving cylinder and the clamping means per se and being operative to be guided on the side walls of the guide slot present in the top part of said moistening space.
  • Fig. 1 the reference numeral 1 indicates the path of an endless conveyor guide in which there is accommodated a conveyor chain 2. This chain runs over reversing sprockets 3 and 4 which have been represented diagrammatically only and of which the sprocket 3 is connected to a drive mechanism 5.
  • This conveyor guide follows an elongated path having two straight parts one of which runs through a moistening space 7.
  • Clamping means 8 spaced apart with respect to each other are suspended from the chain. These clamping means are suspended from the chains in a freely rotatable manner and have been provided with a cylindrically curved driving surface 9.
  • the clamping means are provided with operating means 10 by means of which the spring pressurized not shown clamping jaws may be opened.
  • FIG. 2 With reference to Fig. 2 there is shown in the right hand part the insertion operation performed within the region 6 (Fig. 1).
  • the moistening space 7 there are accommodated two driving belts 11 and 11' which run parallel to the direction of conveyance and which may come into frictional engagement with the cylindrically curved driving surface 9 of the clamping or holding means 8.
  • the belt 11 will force the holding means to rotate to the right and the belt 11' to the left.
  • said belts are both driven by a belt 12 running over rollers mounted on the shafts of the reversing wheels, a drive roller 13 on the shaft of a motor 14 and a tensioning roller 15.
  • a driving roller 16 drives the belt 11 by way of the shaft 17, said belt 11 engaging the cylindrical surface 9 of the clamping means 8, which clamping means is suspended from the chain 2 and is operative to be rotated by means of a not shown bearing present above the cylinder 9.
  • each clamping means is furthermore rotatably mounted in a sealing plate 18; a chain being formed by said sealing plate 18 together with corresponding sealing plates 18'.
  • the moistening space 7 is closed moisture tight to the top thereof, while moreover a stabilization is achieved so that the clamping means will not be able to acquire an oscillating motion under the influence of the unbalance caused by the bundles of leaves. Furthermore the proper engagement with the driving belt will be assured thereby.
  • atomizers 21 for atomizing water.
  • atomizers 22 distributed, like shown in Fig. 1 in the longitudinal direction which atomizers 22 are mounted on a frame 23 which is adjustable in the direction of the height thereof. This adjustment is performed by means of screw spindles 24 and a drive mechanism 25. The adjustment is made between the lowermost position drawn in full lines and the uppermost position shown in interrupted lines.
  • the moistening space is joined to the discharge station 26 accommodated above a transverse conveyor 27.
  • the driving belt 11' extends into this discharge station at which there are provided two guide bars 28 which will engage the operating means 10 projecting at both sides thereof whereby also due to the rotation the clamping means is opened so that the moistened bundle will drop down therefrom.
  • clamping means is of the type that is self locking in the open position to the insert station 6. If such is not the case, the opening of the clamping means at this insert station will have to be brought about in another way.
  • discharge station 26 is provided with an exhaust 29 for exhausting moisture emanating from the moistening space.
  • the entrance and exit of the moistening space may be adapted to the shape of the bundle like indicated by the line 31 in Fig. 2.
  • the moisture leaving the moistening space 7 may be collected in a filter box 32 arranged therebelow and, if desired, may be returned to the liquid supply vessel 33.
  • atomizers by means of which the part of the bundle inserted in the clamping means may be moistened.
