Definitions

  • An apparatus for forming a wrapped tobacco rod comprises a belt for conveying a tobacco stream which contains tobacco in excess of that required in the rod, a feed wheel having a peripheral groove which receives tobacco from the belt, a suction chamber for holding tobacco in the groove along an arc of at least 90 degrees, a trimming device for removing excess tobacco from the stream in the groove so that the remainder of the stream forms a rod, and a wrapping mechanism which applies a wrapper around the tobacco rod.
  • the present invention relates to a method and apparatus for making a tobacco rod for use in cigarette production.
  • a tobacco rod is fed to the rod forming mechanism along a path in which it reverses the direction of its movement by travelling in a vertical plane through an arc of 180 degrees.
  • Such machines include a feed wheel and a tobacco stream feeder belt which surrounds half the span of the feed wheel.
  • the wheel is provided with a peripheral forming channel or groove and cooperates with the feeder belt to form a duct for the tobacco stream.
  • One object of the invention is to provide an improvement in such feed wheels, and the improvement consists essentially in that the introduction of tobacco into the forming channel andthe retention of tobacco in the forming channel is not effected by a conveyor belt or other mechanical means but by suction. ln some cases, compressed air is used to assist in delivering the tobacco stream or rod to the rod forming mechanism.
  • devices may be provided, preferably in the region of the suction feed Wheel, which depend on measured physical factors to directly or indirectly influence the product or to control the effects or causes of variation in such factors.
  • a method of forming a cigarette rod which comprises continuously removing a substantially uniform quantity of tobacco from a distributor or a similar source at a rate sufficient to form a tobacco stream which contains tobacco in excess of that required in the cigarette rod, feeding the tobacco on to a revolving wheel and retaining the stream by suction at the periphery of the wheel, conveying the stream through an iangle of at least 90 degrees, removing excess tobacco from the periphery of the wheel so that the remainder of tobacco forms a tobacco rod, and then wrapping the tobacco rod into a strip of paper to form a cigarette rod.
  • feed wheel preferably comprises a disc provided in its periphery with a forming channel which communicates with a suction chamber and, if desired, with a compressed air chamber.
  • This feed wheel may cooperate with a tobacco conveyor, for example, with a conveyor belt, in such a manner that a portion of the tobacco stream is removed from the conveyor belt by suction.
  • a suitable trimming or levelling device for example, a combing roller, may be disposed beyond the pick-up point to comb olf excess tobacco from the stream carried by the feed wheel so that only a tobacco rod of predetermined cross section corresponding to the cross section of the forming channel at the trimming station is carried forward by the feed wheel.
  • the quantity of tobacco to be conveyed in the forming channel may be varied by displacing the side walls of the forming channel which side Walls may be constructed as axially adjustable rings, or by altering the distance between the trimming device and the bottom wall of the forming channel so that the trimming device removes a greater or lesser portion of the tobacco stream which is being conveyed in the forming channel.
  • the forming channel may be provided with lateral bays or pockets. Because of the greater volume of such pockets, more tobacco is sucked into them than into the remaining parts of the channel. Since such greater accumulations of tobacco are subsequently compacted to equal in cross section the cross section of a normal cigarette rod, the resulting rod may yield cigarettes with portions of greater density at one or both ends.
  • the feed wheel may also be used purely as a conveyor device (e.g., when all of the tobacco which is sucked up by the feed Wheel may be conveyed to a further stage).
  • the conveyor belt which feeds tobacco to the forming channel may follow a part of the periphery of the feed wheel in order to press the tobacco stream into the forming channel during transfer until all of the tobacco received from the belt is effectively held by suction.
  • the tobacco sucked into the forming channel can be compacted to a higher degree, so that the weight or density of the rod is increased. If the suction prevailing in the suction chamber is increased and decreased alternatively, the structure of the tobacco being subjected to suction will be more compact during application of increased suction than during the period when decreased suction is applied. In this way itis possible to produce cigarettes with densely compacted portions at one or both ends, provided that the trimming means is adjacent to a point of the periphery of the feed wheel at Iwhich the suction is also operative to compact the tobacco rod.
  • suction I may be controlled by a measuring device disposed, for example, beyond the rod forming mechanism and operating preferably with corpuscular radiation.
  • the invention covers the control of any factors iniiuencing the rod formation, for example, the delivery of tobacco, by means of a measuring device which is disposed in the region of the suction feed wheel.
  • FIG. 1 is a front elevational view of an apparatus which is constructed in accordance with the invention, certain parts of the apparatus being broken away to illustrate various details.
  • FIG. 2 is an end elevational view illustrating the manner in which the feed wheel is mounted on the machine frame.
  • FIG. 3 is a diagrammatic fragmentary front elevational view illustrating a modified feed belt which is adapted to press tobacco into the channel of the feed wheel.
  • FIG. 4 is a fragmentary end elevational view of a modified channel in the feed wheel, showing a pocket in the channel.
  • FIG. 5 is an enlarged fragmentary section as seen in the direction of arrows from the line A-A of FIG. 1 and illustrates various structural details of the feed wheel.
  • FIG. 6 illustrates the upper portion of the structure shown in FIG. 5 during removal of excess tobacco from the forming channel of the feed wheel.
  • FIG. 7 is a fragmentary section through the feed wheel and illustrates the manner in which the channel forming rings may be adjusted by the use of shims.
  • FIG. 8 is a fragmentary section through the partition walls of a modified feed wheel.
  • FIG. 9 is an enlarged fragmentary end elevational View of the feed wheel and illustrates a perforated bottom wall having a screened area.
  • FIG. 10 is a front elevational view of the feed wheel with the channel forming rings removed to show the openings which are adapted to communicate with suction and pressure chambers.
  • FIG. 11 is a diametral section through the structure of FIG. 10, showing further details of the feed wheel.
  • FIG. 12 shows a conventional measuring device, an adjusting device, and a control device whose fiap controls the degree of suction in the channel of the feed wheel.
  • FIG. 13 shows another control device similar to that shown in FIG. 12.
  • FIGS. l and 2 illustrate a pneumatic conveyor in the form of a feed wheel or suction wheel 3 rotatably mounted on a horizontal shaft 2 which is supported by an arm 18, the latter being fastened to a machine frame 1.
  • a feed including a horizontal conveyor belt 4 (not shown in FIG. 2) is arranged with the upper run of the belt 4 adjoining the lowest part of the periphery of the feed Wheel 3.
  • the uppermost part of the periphery of the feed wheel 3 is arranged beneath a reversing roller 29 for an endless perforated belt 24 of a rod transfer means E (not shown in FIG. 2) which is a suction conveyor and may form part of an entry guide to a cigarette rod forming device.
  • the horizontal lower run of the belt 24 passes under a suction chamber 25 which extends from the reversing roller 29 to a second reversing roller 28 of the transfer device E thereby overlapping a paper strip P which is supported by the horizontal upper run of a forming belt 5.
  • a suction pipe 19 and a compressed air pipe 20 both extending through the machine frame 1 and connected to sources (not shown) of suction air and compressed air respectively.
  • One side of a discshaped wheel body 7 is covered by a stationary cover 17 provided with openings to which are connected flexible hoses 13', 14', 22.
  • the hose 13 communicates with the suction pipe 19.
  • the hoses 14', 22' communicate with the compressed air pipe 20.
  • Blocks 21 and 21 extend between the suction chamber 13 and the compressed air chamber 14 to divide an annular charnber 12 of the feed wheel 3 into two compartments positioned with respect to the suction chamber 13 and the compressed air chamber 14 in a manner to be described later.
  • a bore 22 in the block 21 is positioned beneath the reversing roller 29. One end of this bore communicates with one of a series of radial passages 11 in the wheel 3 and its other end communicates with the hose 22.
  • That portion of the annular chamber 12 which communicates with the suction chamber 13 is continuous from the tobacco-receiving lowermost point of the feed wheel 3 to the uppermost point of the same (adjacent to the rod transfer means E). It might sufce in some cases if suction is maintained along little more than one quarter of the peripheral span of the feed Wheel. Furthermore, the effect of suction may be reduced or eliminated in the zone adjacent to the trimming device. This can be achieved by installing in the suction chamber 13 a block 2lb opposite the trimming device 23.
  • the mounting of the conveyor belt 4 may be modified so that its upper run will have an arcuate portion engaging the lower part of the feed wheel 3, as shown in FIG. 3.
  • the feed wheel 3 comprises the wheel body 7 shown in FIG. 10.
  • This wheel body 7 is provided with the annular chamber 12 which is arranged to receive the stationary blocks 21, 21.
  • the radial passages 11 which are separated by partition walls 15 and covered by a cylindrical perforated member 10 (see also FIG. 9) forming the bottom screen wall of the forming channel 6, connect the annular chamber 12 with the periphery of the wheel body 7. Between the bottom screen wall 10 and the partition walls 15 a small gap 16 is formed to allow for pressure equalization along the bottom of the forming channel 6 when compressed air or suction air is applied to channel 6.
  • Two rings 9, 9 are fastened to the outer edges of the periphery of the wheel body 7 by means of screws 8, 8.
  • the inner sides of these rings define with the bottom screen Wall 10 an annular groove which constitutes the forming channel 6. If the inner sides of the rings 9, 9' are fiat, the channel 6 will have a constant width.
  • differently shaped rings 9, 9 may be used, as shown in FIG. 4, to form pockets 27 by providing the inner sides of the rings 9, 9' with recesses located opposite each other.
  • the trimming device 23 which may be adjustable radially of the wheel 3 is shown in FIG. 6 in the form of a rotary brush.
  • the position of this :brush determines the effective height h of the channel 6 through which the tobacco stream advances between the inner sides of the rings 9, 9' and the bottom screen wall 10.
  • the distance b lbetween the rings 9, 9 may be adjusted in the axial direction of the wheel 3 by the use of shims 26, as shown in FIG. 7 for the ring 9.
  • FIG. 8 A modified arrangement of partition Walls 315 is shown in FIG. 8.
  • FIG. 9 shows the mounting of the bottom screen wall 10 in the peripheral groove of the Wheel body 7.
  • the wall 10 overlies the partition walls 15 and the radial passages 11.
  • the apparatus of my invention operates in the following manner:
  • This channel ⁇ 6 is subjected to the action of suction in the region of the suction chamber 13 extending over the left-hand reversal point of the endless belt 4 and, therefore, tobacco is picked up by the rotating feed wheel 3.
  • any tobacco projecting beyond the outer radial limit of the forming channel 6 is taken off by the trimming device 23, for example, a combing roll, a brush or the like and, if desired, such trimmed-off excess tobacco is returned to the tobacco delivery point.
  • the trimming device 23 there is situated in the forming channel 6 a tobacco rod of uniform and exactly predetermined cross section corresponding to the cross sectional area of the passage formed by the channel 6 and trimming device 23.
  • this tobacco rod is held by the action of suction in the forming channel 6.
  • the suction chamber 13 terminates so that the rod situated in the forming channel 6 is no longer held.
  • the density of the tobacco rod cannot be influenced by the previously described means of varying the cross sectional area of the passage defined jby the channel 6 and trimming device 23.
  • In order to vary the density it is possible, for example, to increase suction in the suction chamber 13 so that tobacco sucked into the forming channel 6 becomes more compact.
  • suction may be increased intermittently by known means in the suction chamber 13 (for example, by a valve in the suction conduit 19) to compact the tobacco intermittently in the channel 6.
  • the trimming device 23 should be mounted at any point along the periphery of the feed wheel 3 at which the suction exerts a compacting inuence on the t0- bacco rod. This can 'be achieved .by removing the block 2lb from the suction chamber 13.
  • a tobacco rod with spaced denser portions is also possible by utilizing a channel as shown in FIG. 4.
  • This channel is provided with pockets at appropriate distances from each other. iMore tobacco is sucked into such pockets than into the narrower parts of the channel 6.
  • the cigarette rod will have a denser structure at spaced points.
  • the forming channel 6 is dimensioned in such a Way that it can receive all of the tobacco from the belt 4, and a levelling or trimming device 23 for removing excess tobacco is not required.
  • a measuring device can be disposed in the region of the feed wheel 3, especially in the suction chamber 13, so as to provide rays shown in broken lines in FIGURE 8 and may serve to control any desired factor inuencing the rod y formation, for example, the tobacco delivery. It is necessary to insure that the measured results are not iniiuenced or else are influenced only in a manner that can easily be corrected by structural parts projecting into the path of the rays. If, for example, the source of the rays is mounted in the suction chamber 13, then, and as shown diagrammatically in FIG.
  • the partitions 315 of the radial passages 11 in the rotating wheel body 7 may be positioned non-radially so that the measuring rays originating from the radiation source and masked by an axially extending slot constitute with respect to the passing partitions 315 trajectories which are indicated Iby broken lines and each of which intersects the partitions 315 so that their resistance is constant whatever the angular position.
  • the radiation source could be so positioned that the rays penetrate the tobacco situated in the forming channel 6 in an axial direction.
  • Suitable measuring and control devices may be arranged to regulate suction in the channel 6 of the feed wheel 3.
  • the suction pipe 19 is provided with a nipple 38 whose opening may be closed by a pivotable ap 37.
  • This flap 37 is pivotally attached to an adjusting link 36 which in turn is actuated by an adjusting device 35.
  • a measuring device 30 located adjacent to the belt 4 (FIG. 1) is connected by a line 31 with a control device 32 (FIG. 12) which in turn is connected with control lines 33 and 34 leading to the adjusting device 35.
  • the measuring device 30 detects any undesirable variations in the tobacco stream and transmits electrical impulses to the control device 32.
  • the control device 32 transmits an electrical signal to the adjusting device 35 which thereupon imparts a mechanical motion to the adjusting link 36 so that the link adjusts the position of the ap 37, thereby increasing or decreasing the rate of flow of outside air into the pipe 19 and hence decreasing or increasing, respectively, the effect of suction in the channel of the feed wheel 3 to an extent determined by the measuring de-vice 30.
  • a ap 137 is centrally pivoted in the suction pipe 19 and is connected yby a linkage 136:1 to an adjusting lever 136.
  • the operation of this arrangement is similar to that of the arrangement shown in FIG. 12 excepting that the ilap 137, when operated by the adjusting device 35 through the adjusting lever 136 and linkage 136a, varies the resistance to the ow of suction to an extent determined by the measuring device 30.
