Definitions

  • the present invention relates to a distributor which is designed to feed the devices for forming the rod of tobacco of a cigarette-forming machine in such manner that the blended stock is supplied at a rate which is both constant and uniform.
  • the distributors which perform these operations mainly consist of a cylindersometimes a conveyor belt which is fitted with spikes or cards and which is covered in a continuous manner with shreds or bunches of shreds, these latter being stripped by the cards from the mass of tobacco which is made available at the upstream or input end and which is referred-to as a volute.
  • the carding device conveys the tobacco and causes it to pass beneath an equalizer which is usually constituted by a cylinder which is fitted with very fine wire teeth card clothing and which is tangent to the previous cylinder along a generator-line and rotating in the same direction.
  • the said equalized forces back any excrescences of shredded tobacco which may be carried by the carding unit.
  • the shreds conveyed through the carding unit are extracted from this latter by a crumbler, which is a cylinder of small diameter fitted with cockspurs, the tips of which penetrate between the rows of wire teeth of the cards.
  • the rain of flakes produced by the crumbler falls onto a traveling band on which a certain blending process takes place by reason of the fact that a same point of the said travelling band receives flakes which are derived from various points of the carding machine.
  • the said blend is further improved as and when the flakes are transferred from the band to the tobacco feedbelt which is perpendicular to this latter.
  • the majority of forming machines are provided, prior to the final formation of the rod of tobacco, with one or a number of regularizing devices (peak clipper, rod-compensator, weighing device controlling the speed of the carding unit, etc.).
  • the present invention is directed to the construction of a distributor which is capable of supplying a forming machine with tobacco flakes in a continuous stream at a momentary rate which is as constant as possible and having a composition which is as homogeneous as possible, particularly from the point of view of size distribution.
  • the distributor in accordnace with the invention comprises, at the output end of a feeder and separator device designed to effect a substantial separation of the bunches of tangled shreds, means for selecting the shreds from at least two groups of shreds of different lengths, and adjustable means for the distribution of shreds associated with said selecting means and intended to deliver in a uniform manner and in requisite proportions a stream which is composed of shreds of the corresponding group.
  • the distributor in accordance with the invention accordingly makes it possible to obtain a constant and uniform blend by carrying out the blending process according to the percentage of shreds of each group which exist in the initial product to be blended.
  • the means for selecting the shreds according to their dimensional characteristics are preferably constituted by screening surfaces provided with perforations of different size from one surface to the following surface and to which are imparted a movement which ensures the onward progression of the stream, for example by means of flat screens to which are imparted shaking movements.
  • the adjustable distribution means associated with the selection means can be constituted by tanks or wells, the bottom of which being formed by a screening surface provided with perforations of a size at least equal to the size of perforations characterizing respectively the selection means which are associated therewith, and to which are imparted vibrational movements of variable frequency and amplitude.
  • the screen which forms the bottom thereof is in a so-called saturated state, or in other words the delivery of the said 3 screen then depends only on the amplitude and the frequency of the vibrational movement imparted thereto. It is accordingly merely necessary to produce action on these two variables in order to introduce into the final blend the shreds of each group according to the same proportions already existing in the initial product.
  • pre-screening means between the separator device and said selection means and which are designed to permit the passage only of those shreds having a size either equal to or very slightly larger than that of the group corresponding to the largest size selected by said selection means.
  • a carding and crumbling unit is provided at the output end of the said means, and conveyor means bring back the said shreds after carding and crumbling to the input end of the said selection means.
  • FIG. 1 is a diagrammatic vertical sectional view of the complete device
  • FIG. 2 is a plan view with portions broken away, of the device of FIG. 1;
  • FIG. 3 is a view in end elevation of one of the distribution tanks
  • FIG. 4 is a partial view in side elevation of one of the tanks showing the elements which produce the vibrational motion
  • FIG. 5 is a partial sectional view taken along the line aa of FIG. 4;
  • FIG. 6 is a partial plan view corresponding to FIG. 4, and
  • FIG. 7 is a diagrammatic vertical sectional view of an alternative form of the device as a whole.
  • the device which is intended to feed the units for forming the rod of tobacco of a cigarette-making machine essentially comprises:
  • a feeder and separator 1 a shaker conveyor 2 which is driven by a motor 3 and which comprises a number of selection or screening zones 4, 5, 6, the meshes of which have increasing sizes, a travelling band 7 which is fitted with brushes and which is intended to unclog periodically the meshes of the screens and, beneath the zones 4, 5 and 6, distribution tanks 8, 9, 10.
  • the tanks 8, 9, 10 which are held in position between frames 11 are mounted on springs or the like elastic support 12, there being imparted to the said tanks a vibrational movement which is transmitted thereto by a motor through the intermediary of a shaft 13, eccentrics 14 and connecting-rods 15.
  • the plane of vibration is in this case horizontal.
  • screens 16 which form compartments 18, 19, 20 and screens 17 which form the bases of the said tanks.
  • Each base is mounted beneath one of the screening zones 8, 9, 10 respectively, and the size of mesh of the screens fitted in said bases is at least equal to that of the screens of the corresponding zones 4, 5, 6.
  • An endless belt conveyor 21 collects in proper sequence the flakes which are dispensed by the tanks 8, 9, 10.
  • a device of conventional type comprising a belt conveyor 22 or a carding cylinder, combs 23 and a crumbling cylinder 24 is arranged at the downstream end of the screening zones. Vibrating bands or passageways 2'5, 26 and 27 collect the shreds which have been separated and crumbled and convey them to the input end of the feed on the shaker conveyor 2.
  • the shreds of tobacco are introduced at 28 and, after a substantial separation process which does not impair the shreds, are directed by means of the feed separator 1 onto the shaker conveyor 2.
  • the stream of tobacco shreds moves forwards over the screening zones 4, '5, 6 and successively abandons those shreds which are considered to be of maximum size for the purpose of constituting an homogeneous blend of uniform compactness.
  • the screening zones can be constituted by screens having respectively 14, 8 and 5 meshes per inch. The size of mesh can vary as a function of the size distribution of the standard-grade tobacco employed.
  • the area of the screening zones and the sizes of the tanks are regulated in relation to the speed of the devices for forming the rod of cigarette-tobacco, in such manner as to ensure suitable frequency and amplitude of the vibrational movements imparted to the shaker conveyor and to the tanks.
  • the area of the screening zones will be regulated as a function of the required delivery of shreds of the category which can be screened in each zone, the said delivery depending also on the size composition of the type of cut tobacco employed.
  • the rate of delivery of a screen filled with a product which is intended to pass through the mesh of said screen is a function of the depth of the layer of product supported.
  • the delivery first increases, then tends to become stable, irrespective of the depth.
  • the screen is then said to be saturated.
  • the delivery of the screen then depends only on the amplitude and frequency of the vibrational movement.
  • Suitable adjustable means A are provided to adjust the frequency and amplitude of the vibratory motion of the tanks.
  • each column 8, 9, 10 must satisfy two conditions. In the first place, it must be saturated. In the second place, the ratio of the delivery thereof to the total delivery of the distributor is equal to the average percentage of sheds present in the cut tobacco which are capable of passing through the mesh (and through the corresponding tank).
  • the said percentage is subject to random variations, the effects of which are damped by the top screen or screens 16 of the tank.
  • the variations in level in the said screen or screens results in varti-ons in deliverywhich become smaller as the depth of product progressively approaches saturation point which have no effect on the delivery of the bottom screen 17 if this latter is saturated.
  • the belt conveyor 21 which is placed beneath the tanks 8, 9, effects the blending of the various products fed through the screens and the transportation of these latter towards the tobacco feed band.
  • the shreds which pass over the screens are evacuated at the downstream end of the shaker conveyor.
  • These oversize rejects which are mainly composed of shreds having a length which is greater than the limit fixed by considerations of uniformity of the rod of tobacco, are then received on the carding belt 22 which passes through the combs 23 and the crumbling cylinder 24-.
  • the stream which passes out of the carding and crumbling unit is re-introduced as a continuous process at the input end of the shaker conveyor by a transporting means which is in this case consituted by vibrating bands or passageways 25, 26, 27. Since the point of re-introduction 29 is located at the upstream end of the main tobacco intake, those shreds which have been transferred through the carding and crumbling unit are screened first, by virtue of the fact that they are located beneath the input stream.
  • the mesh of the said screens is equal to or very slightly larger than the largest selection meshes, that is to say the mesh of the screen 6.
  • the screened portion of the pre-screening system falls onto the shaker conveyor 2 and continues to travel directly towards the selection screens 4, 5, 6.
  • the oversize material rejected by the pre-screening system 30, 31 passes into the carding cylinder 32 and crumbling cylinder 33, at the output end of which the said material joins the previous stream on the passageway 2.
  • a feed distributor for a cigarette-making machine comprising a feeder means for effecting a substantial separation of the bunches of tangled tobacco shreds, separating means for separating a portion of the shreds coming from said feeder means into at least two groups of shreds of different increasing lengths and temporarily storing a reserve thereof, a first conveyor means to carry said at least two groups of shreds to the cigarette-making machine, means for distributing each of said groups of said separated shreds onto said first conveyor means at a predetermined rate, means for adjusting the rate of distribution of each of said distributing means whereby said stream carried by said first conveyor means comprises predetermined proportions of said different groups of separated shreds, means for conveying another portion of the shreds rejected as oversize from said separating means to a location downstream of said separating means, means located at said location downstream of said separating means for carding and crumbling the shreds rejected as oversize by said separating means, and second conveyor means to bring back said oversize shreds after carding and crumbling upstream of
