Definitions

  • a distributing device for tobacco for permitting the uniform supply of processing -machines with a continuous ow of material which has a contant bulk density without damaging the material.
  • a duct composed of a series of sections, the cross sections of the sections decreasing in consecutive order, and paddle wheel carrying drums rotatably located in shoulders in each one of the sections, which drums are rotated with speeds increasing from one to the other successive section.
  • the main object of the present invention is to permit the uniform supply of processing machines with a continuous flow of material having a predetermined shape .and constant bulk density without causing degradation of said material.
  • the elements of the apparatus according to the invention make profitable use of the regulating action of this design by associating it with devices which produce action on the flow rate according to forms of construction which cause the material conveyed to form a stream of smaller cross-sectional area from the upstream end to the downstream end of the machine. It is readily apparent that, in order to prevent packing of the material, it is advisable to ensure that these devices impart to the stream of material an additional speed in proportion to the reduction in cross-sectional area. Broadly speaking, it is within the field of the invention to associate with means for reducing the cross-sectional area of tlow of a stream of material devices for the purpose of accelerating said stream of material in such a manner as to maintain a volume rate of ow which is at least equal.
  • the stream can follow a passageway which is open on one or Patented June 17, 1969 ice a number of sides or a closed duct.
  • the shaping-of the stream can be effected at the sides, the devices employed for increasing the speed being, for example, endless belts or alternatively cylinders which work at a more or less substantial depth within the stream.
  • the material is transported in a duct composed of a series of segments of constant cross-section which are joined by reduction zones in which the devices for accelerating material are placed.
  • the devices referred-to can be constituted by one or a plurality of drums rotatable about their axes and adapted to carry active elements which sweep in counterflow to the main stream those sectors of the reduction zones which do not open into the downstream duct segment, thereby redirecting the material towards the reduced stream.
  • the active elements will be in the form of teeth or paddles depending on the type of material conveyed and on the secondary effect desired.
  • each rotary drum or paddle wheel of the type referred-to could be substantially perpendicular t0 the general direction of the stream. Provision can be made in a given reduction zone, for example, for two paddle wheels which are adapted to rotate in opposite directions and housed in two oppositely-facing shouldered portions.
  • the active elements of these paddle wheels can be adapted to intersect in the central portion of the stream if they rotate at the same angular velocity.
  • degradation of material will be reduced by assigning to each paddle wheel a separate work sector which will always comprise practically the entire volume of the shouldered portion.
  • a standard assembly consists of two identical paddle wheels having parallel axes and adapted to rotate at the same speed in opposite directions, the active elements of said paddle wheels being adapted to describe two surfaces of revolution which are tangent to each other and which closely conform to the shells constituting the shouldered portions.
  • the rotary paddle wheels have ⁇ a tendency, as mentioned earlier, of returning in counterflow to the main stream that part Of the material which flows towards the shouldered portions.
  • one homogeneous solution consists in providing at the head of the apparatus a supply duct of similar design to the ducts described above in reference to tobacco torrefiers.
  • the volume rate of ilow is caused to vary by either increasing or reducing the'angular velocity of all the paddle wheels in the same ratio. It will therefore be an advantage to drive said paddle wheels from a single motor.
  • the speed of the set of rotary paddle wheels of one stage as a function of the supplied data relating to the filling of duct sections either upstream or downstream, it is advisable to provide for each set of paddle wheels control devices which can be disconnected from the others.
  • the data referred-to above can be supplied either by photoelectric detectors or by micro-switches which are responsive to the pressure exerted by the material on a predetermined sector of the walls.
  • FIG. l is a cross-sectional view .of the apparatus on a rst vertical plane of symmetry
  • FIG. 2 is another cross-sectional view of the apparatus on a second vertical plane of symmetry at right angles to the iirst.
  • the apparatus is essentially composed of a hollow body -1, all the horizontal cross-sections of which are rectangular.
  • Said body is shown to be mainly constructed in the form of a stack of vertical-walled duct segments Z, 3, 4, 5, 6 which are joined to each other by quartercylinder sectors 7, 7', 8, 8', 9, 9', 10, 10'.
  • Two of the opposite 'walls of two adjacent duct segments are always located in the same plane.
  • one of the dimensions of the lower duct segment is only one-half the corresponding dimension of the upper duct segment.
  • the duct segments 2 and 3 have the same depth in the plane of FIG. l but the width of the duct segment 2 is twice that of the duct segment 3.
  • the duct segments 4 and 5 have the same width in this figure plane but the depth of the duct segment is one-half the width of the duct segment 4.
  • Two paddle wheels 12 and 12' are rotatably mounted within said bulges; the rotational axes 13 and 13 of said wheels are therefore located in the plane of the bulged walls and the paddles are adapted to skim over the internal surfaces of said walls as they move in rotation.
  • 10' is fitted with a similar wheel 14, 14', 16, 16', 18, 18', 20, 20' having a horizontal axis 15, 15', 17, 17', 19, 19', 21, 21'.
  • the rotational axis of a wheel is located in the line of extension of the plane of the wall of the downstream portion of the duct.
  • the dimensions of the wheels 14, 14', 16, 16', 18, 18', 20, 20' are such that each set of two wheels sweeps the entire junction zone between two duct segments.
  • the Wheels of a same set rotate at the same speed and in opposite directions.
  • the recesses formed between their paddles are displaced by one-eighth of a revolution from one wheel to the next in order that they should not discharge material at the same time and in order to prevent any shearing of material.
  • the speed adopted for the wheels 14 and 14 will correspond to a value which is higher than 2n such as, for example, 3n.
  • the speed of the wheels 16 and 16' will be 9u and so forth up to the wheels 20 and 20' which will rotate at a speed of 81n.
  • Cut tobacco which is fed in a fairly uniform manner into the top of the body 1 will be returned to the duct segment 2 by the paddle wheels 12 and 12' with greater uniformity.
  • the wheels 14 and 14 will increase the velocity of falling motion of the tobacco so that the duct segment 2 will never be choked and will accordingly permit of variation in the level of tobacco.
  • the same process will take place from one duct segment to the next and the wheels 20 and 20' will deliver at the outlet a uniform flow of tobacco which has the desired crosssectional area and which has sustained only the minimum amount of degradation.
  • the starting or stopping of either all or some of the paddle wheels 12-14-16-18 and 20 can be performed either by means of photoelectric cells which react to the presence or absence of material within one of the duct segments 2-3-4-5-6 or by means of micro-switches which react to the pressure exerted by the material on the walls of said duct segments; said micro-switches can evidently be replaced by any other suitable detector element which is responsive to the lling density at the level of said element.
  • zones of reduction in transverse cross-section constitute shouldered portions of the duct, said rotary devices being entirely within said ducts and being mounted in said shouldered portions.
  • said duct comprises at each zone of reduction in transverse cross-section two shouldered portions which are in oppositely-facing relation and a rotary device mounted in each of said shouldered portions, each adapted to rotate in a direction opposite to the ⁇ direction of rotation of the oppositely facing one.
  • each reduction of section is the result of the reduction of only one of the dimensions of said rectangular shape.
