Definitions

  • the invention relates to a device for distributing tobacco, such as tobacco fibers, tobacco leaves or parts of tobacco leaves having the features of the preamble of claim 1.
  • Devices for distributing tobacco such as tobacco fibers, tobacco leaves or parts of tobacco leaves are generally used when the tobacco is to be distributed in a mass flow with a narrow width and uneven thickness to a greater width with a uniform thickness for delivery to another device ,
  • Such a further device may e.g. be a device for the detection of foreign bodies, in which the tobacco should be performed in a thin and even layer so that the foreign body or foreign particles can be detected as well as possible.
  • An exemplary magnitude of the distribution of the tobacco is e.g. a supplied mass flow of tobacco, which is heap-shaped in cross-section, and has a width of 800 mm and is to be distributed to a mass flow to a width of 1700 mm with a uniform and small thickness.
  • the devices are each formed by profiled rollers which singulate the tobacco fibers or distribute them over a greater width.
  • known tobacco cutting machine has a spherical feed roller with arrow-shaped corrugations, which displace the tobacco fibers from the center to the outside, so that the tobacco fibers are distributed by a mass flow in cross-section mass flow to a more uniform mass flow.
  • Both devices are common in that the tobacco fibers are passed under the rollers and displaced due to the profiling of the rolls in the width and / or isolated.
  • the object of the invention is to provide a device with which the tobacco fibers can be spread evenly and gently over the shortest possible distance to the widest possible width.
  • a device for distributing tobacco such as tobacco fibers, tobacco leaves or parts of tobacco leaves with a rotationally driven about its longitudinal axis of the first profile drum, which is a tobacco fibers from the center outwardly distributing arrangement of to the longitudinal axis of the profile drum has obliquely directed guide bodies, and is provided in the at least one second profile drum with inclined guide bodies, which is arranged in the transport direction of the tobacco fibers behind the first profile drum, proposed in which the guide body on at least one of the profile drums at least in a section as parallel aligned single ribs are formed, which are interrupted in the circumferential direction.
  • the advantage of the proposed solution is the fact that the tobacco is taken over at least in a partial stream after distribution over the first profile drum of the second profile drum and is further distributed to an even greater width. Due to their orientation, the obliquely directed guide bodies effect a distribution of the tobacco out of the center into the edge areas, so that the tobacco as a whole is distributed to a mass flow having a greater width and a smaller thickness.
  • the proposed design of the guide body of the tobacco can be particularly evenly distributed, without causing the risk that accumulates the tobacco and hinders the onward transport.
  • the tobacco is distributed by the proposed shape of the guide evenly outward to a greater width, each single rib displaced for itself a subset of the tobacco.
  • conductive body-free sections are deliberately created in which the composite of the tobacco displaced to the outside can loosen again before the tobacco is distributed by the intervention in the next lattice structure of the same profile drum or the next profile drum farther out.
  • the second profile drum is driven in the same direction as the first profile drum.
  • the same direction of rotation of the second profile drum is of particular advantage, since the tobacco is thereby further transported at the output of the first profile drum of the top of a rectilinear motion exporting guide bodies of the second profile drum, so that at least a portion of the tobacco fibers is passed at the top of a profile drum to the next profile drum.
  • the guide bodies are moved in the opposite direction in the region of the gap between the profile drums, that is, the guide body of the first profile drum perform a downward movement, while the guide body of the following profile drum perform an upward movement in the region of the gap.
  • the guide bodies are arranged at an angle to the longitudinal axis of the profile drum. Due to the angled orientation of the single ribs, the tobacco is automatically displaced to the task on the profile drum to the outside. How far the tobacco is distributed to the outside can be adjusted by measuring the angle between the individual ribs and the longitudinal axis.
  • the profile drums are arranged parallel to each other, in such a way that a gap of 1 mm to 20 mm between the wrapping webs is present, which are defined by the rotating during the rotation of the profile drums, radially outer edges of the guide body.
  • the parallel arrangement of the profile drums results in a special uniform distribution of the tobacco fibers, which can be prevented by the gap that the movement of the profile drums is blocked by trapped tobacco fibers or other particles. Furthermore, part of the tobacco fibers can consciously fall through the gap, so that the amount of tobacco fibers transported on the profile drums is reduced.
  • the gap width represents an important design parameter, which decisively influences the distribution of the tobacco fibers. Furthermore, larger clumps of contiguous tobacco fibers in the gap can be gently dissolved into smaller lumps or individual tobacco fibers.
  • the profile drums have an outer diameter of 100 to 200 mm and are driven to a rotational speed of 50 to 200 U / min.
  • At least a third profile drum is provided, which is driven in opposite directions to the first profile drum.
  • the oppositely driven profile drum can actively support the removal of the tobacco fibers through the gap, since the opposite surfaces of the profile drums in the region of the gap in the same direction, e.g. down, to be moved.
  • the profile drums are driven synchronized. Due to the synchronized drive, the movements of the profile drums can be matched to one another, which is, for example, is useful in a possible meshing of the profile drums or a startup or shutdown of the device.
  • the synchronized drive can e.g. be realized by the use of a common drive means or by the use of coupled individual drives.
  • At least one of the profile drums is formed from two individual rollers, and the individual rollers are arranged such that the longitudinal axes of the individual rollers at the feed direction of the tobacco fibers facing side enclose an angle of greater than 180 degrees between them.
  • the individual rollers thereby form a kind of roof structure, whereby the resulting tobacco fibers are distributed by gravity automatically from the middle to the edges.
  • the guide bodies are adjustable. Due to the adjustability of the guide bodies, the distribution process can be adapted to the different nature of the tobacco, e.g. the sheet size, to be adjusted. Further, by the adjustability of the baffles, the distribution per se, e.g. also on-line, by means of an iterative Nachver ein be optimized.
  • the guide body are adjustable so that the angle of the guide body is variable to the longitudinal axis of the profile drum, since this for the distribution of the tobacco mass flow in the width is the decisive factor.
  • the guide bodies are adjustable in groups at least by a common adjusting device.
  • the guide body can be adjusted in groups, so that the guide body of at least one group in the ideal case always have the same orientation to each other. Furthermore, thereby the entire adjustment of the guide body can be considerably simplified.
  • FIG. 1 is a device according to the invention with four profile drums 3,4,5 and 6 can be seen.
  • the profile drums 3,4,5 and 6 are arranged parallel to each other and rotatably mounted at their ends to continuous housing walls 1 and 2.
  • the housing walls 1 and 2 are part of a parent housing or frame and can be considered as fixed to each other. Due to the mounting of the ends of the profile drums 3,4,5 and 6 on each of the housing walls 1 and 2, the profile drums 3,4,5 and 6 are also in a fixed immutable parallel alignment with each other, the longitudinal axes of the profile drums 3.4 , 5 and 6 are arranged in a plane so that the profile drums 3,4,5 and 6 in the averaging practically form a plane to which the tobacco is added as will be described below.
  • the term tobacco is to be understood as meaning tobacco fibers, tobacco leaves, parts of tobacco leaves, with the term tobacco being used below for the sake of simplicity as a representative of the term tobacco.
  • the profile drums 3,4,5 and 6 are each driven in the same direction in the arrow directions A, B, F and G rotatory and preferably synchronized.
  • On the profile drums 3,4,5 and 6 respectively two groups of obliquely directed to the longitudinal axes of the profile drums 3,4,5 and 6 guide body 7 and 8 are arranged, which form an arrow shape to each other.
  • the guide body 7 and 8 are each single ribs of equal length, which are formed for example by welded baffles with a height of 10 to 30 mm and a length of 50 mm to 200 mm.
  • the baffles are each aligned at an angle C and D of 10 to 40 degrees to the longitudinal axis Z of the profile drums 3,4,5 and 6, as in the FIG. 2 1, and include an angle E to an arrow shape of less than 180 degrees in the direction of transport T between them.
  • the profile drums 3,4,5 and 6 are positioned on the housing walls 1 and 2 such that between the envelopes 9 and 10 defined by the outer edges of the guide bodies 7 and 8 during the rotation, a gap S of 1 to 20 mm, preferably of 10 mm, which can reduce the likelihood that solids between the profile drums 3,4,5 and 6 can clamp, and also a part of the tobacco fibers deliberately between the profile drums 3,4,5 and 6 falls through. Furthermore, the tobacco fibers, which fall through the gap S and adhere to each other, are gently dissolved into individual tobacco fibers.
  • the profiled drum 3 is formed by a drum and has, on the outside, the guide bodies 7 and 8 arranged in a grid structure 11.
  • the guide bodies 7 and 8 are arranged in a plurality, preferably four grid structures 11 arranged parallel to one another, wherein in each case regions 15 are provided between the grid structures 11 which have no guide bodies 7 or 8.
  • the mass flow H of tobacco fibers on the conveyor belt 16 in the transport direction T in the width and the thickness increases steadily until the tobacco fibers are finally transported away in a gleichracetem and wider mass flow H on the conveyor belt 16.
  • Decisive for the broadening of the mass flow H of tobacco fibers are the speeds of the profile drums 3,4,5 and 6, the widths of the column S, the orientation of the guide body 7 and 8, and the width and distribution of the tobacco fibers in the profile drum 3 discontinued mass flow T1.
  • the proposed values have been found to be preferred, wherein a broadening of the mass flow of tobacco fibers from a width of the supplied mass flow T1 of 800 mm to a width of the discharged on the conveyor belt 16 mass flow H of 1700 mm at a rotational speed of the profile drums 3,4, 5 and 6 of 100 U / min at a circumference of about 400 mm of the profile drums 3,4,5 and 6 and a width of the column S of about 10 mm with a satisfactory distribution of the tobacco fibers in the mass flow H can be realized.
  • a vibrating chute which further distributes the tobacco fibers by a vibration.
  • the distribution effect can be further assisted by forming the profile drums 3,4,5 and 6 from two individual drums 3a and 3b, which, as in US Pat FIG. 4 can be seen, roof-like arranged at an angle V of greater than 180 degrees to the feed direction P of the tobacco fibers. Due to the arrangement of the individual drums 3a and 3b, the tobacco fibers move in this embodiment, gravitational automatically from the center out to the edges of the individual drums 3a and 3b, whereby the distribution effect can be further supported.
  • the guide body 7 and 8 and the baffles can also be made adjustable by a common adjustment, in particular, the angle C and D should be variable to make the distribution variable. It would also be conceivable to adjust the guide bodies 7 and 8 individually or in groups, so that the distribution can be set to a predetermined distribution profile, or the distribution to the edges can be limited. A limitation of the distribution can be achieved, for example, by adjusting the guide bodies 7 and 8 at the edge to an angle C and D of 90 degrees.
  • the guide body 7 and 8 can be stored, for example, in each case about an axis of rotation perpendicular to the respective longitudinal axes Z of the profile drums 3,4,5 and 6.
  • the guide bodies 7 and 8 obliquely in the circumferential direction of the profile drums 3, 4, 5 and 6, and optionally to adjust this angle by the adjusting device, whereby the transport movement of the tobacco stream can be further changed.
  • the guide body 7 to the right of the center axis and the guide 8 to the left of the center axis each form a group with an identical orientation at an angle C and D to the longitudinal axes Z of the profile drums 3,4,5 and 6, which be adjusted together as a group during an adjustment.
  • the adjustment is carried out such that the angles C and D are identical in size and the symmetrical arrow profile is maintained.
  • the common adjusting device may preferably comprise a common adjusting mechanism which can be actuated manually or by a controllable drive device.
  • a controllable drive device would also allow the possibility of regulating the orientation of the guide body, so that the geometry of the tobacco stream according to a predetermined profile by the adjustment of the guide body 7 and 8 is controllable.
