Definitions

  • This invention concerns improvements in or relating to tobacco-manipulating machines (for example continuous rod cigarette-making machines) in which a continuous tobacco filler is formed, which filler (for example after being enclosed in a paper wrapper) is to be cut at intervals to form individual tobacco articles such as cigarettes.
  • tobacco-manipulating machines for example continuous rod cigarette-making machines
  • filler for example after being enclosed in a paper wrapper
  • the filler although trimmed to uniform cross-sectional size, will vary in weight. It is usually desired that the tobacco articles produced from the filler (e.g. cigarettes) should as far as practicable be of uniform weight, and for this purpose the weight per unit length of the tiller should as far as practicable be uniform.
  • a tobacco-manipulating machine such as a continuous rod cigarette-making machine
  • means to form and feed forwardly a tobacco stream whose cross-sectional size is greater than required a trimming device to remove surplus tobacco from the stream
  • a measuring device arranged to measure the quantity of tobacco in a part of the stream close to the said trimming device
  • adjusting means responsive to measuring operations by the said measuring device to cause relative movement, laterally of the stream, between the stream and the trimming device, so as to vary the cross-sectional size to which the stream is trimmed.
  • the last-named means may comprise means to move laterally a conveyor by which the stream is conveyed, so that a part of the stream is moved towards and away from the trimming device.
  • laterally is meant in a direction transverse to the direction of lengthwise movement of the stream.
  • the stream may pass nitc States Patent beneath the trimming device and may be supported by a conveyor tape which can be raised or lowered in order go move the stream towards or away from the trimming evtce.
  • a tobacco-manipulating machine such as a continuous rod cigarette-making machine
  • a part of the channel which supports a tobaccoconveying band may be moved towards and away from. me trimming device.
  • the said measuring device may be arranged to measure that part of the stream which has just passed the trimming device.
  • Figure 1 is a longitudinal section showing the feed end of a cigarette-making machine in which a tobacco stream is formed
  • Figure 2 is a similar view showing on a larger scale the trimming device for separating and removing the excess tobacco, and its adjustment device;
  • Figure 3 is a sectional view of the same device, the section being taken upon the line 3-3 of Fig. 2;
  • Figure 4 is a block and wiring diagram of the electric circuit for regulating the average density of the cigarettes.
  • the tobacco is spread by a distributor 1 on to an endless travelling band 2 between the walls 3 and 4 of a shoot-type hopper.
  • a stream of tobacco is thus formed and fed forwardly on the band 2 from the rear wall 3 to the leading wall a of the hopper, the tobacco being supplied at a sufiicient rate to form a stream whose cross-sectional size is greater than required.
  • a trimming device is arranged to separate and remove any excess tobacco from the stream 8.
  • this device is illustrated diagrammatically in the form of a pair of circular disc-like cutters 12.
  • the band 2 travels through a channel which forms it, in the region of the trimming device, to U cross-section.
  • a measuring device 25 for detecting any variations in the density of the tobacco stream which is to be subsequently utilized in the actual cigarettemakiug process.
  • the stream is delivered on to an endless paper web 9 guided by a small roller 10 and supported thereafter by an endless band 11 which carries along the paper web loaded with tobacco through the cigaretteforming members.
  • the device for removing the excess tobacco above the selected level comprises a pair of rotary circular cutters 12 overlapping each other by about .04" and rotating at a peripheral velocity exceeding by about 15% the linear speed of the band 2.
  • the excess tobacco, which extends above the cutting plane, is trimmed off by the cutters and returned to the distributor by a suitable device (not shown).
  • the channel through which the band 2 moves under the cutters 12 is formed by bars 23, guides 24, and a vertically adjustable bed plate 13.
  • the channel has,-in the assess:
  • this section (Fig. 3) can be varied from about W to 1%".
  • the vertical position of the bed plate 13 is adjusted automatically by a servomotor 14.
  • This servo-motor comprises a reduction gear 15 driving a chain sprocket 16 mounted on a shaft 17 and adapted to drive another chain sprocket 18 mounted on the shaft 19.
  • This shaft 19 is formed with a screw-threaded portion engaging an internally screw-threaded member 20 secured on a slidebar 21 arranged to slide on a fixed guiding support 22.
  • This slide-bar 21 is integral with the bed plate 13.
  • the servo-motor 14 is adapted to rotate in either direction and its movements are controlled by the de tecting device.
  • the bed plate 13 remains in its position of adjustment; when the motor rotates in one direction, the bed plate 13 rises, and when the motor rotates in the other direction, the bed plate 13 descends.
  • the travelling band 2 follows the up and downward movements of the bed plate 13, the latter having a concave rounded upper face and the band having its lateral marginal portions extending to a greater or less extent into the gap left between the bars 23 and guide members 24.
  • a measuring or detecting device 25 which may be of any known and suitable type, is positioned just beyond the trimming zone, and supplies an electric current whose voltage and strength are determined by the mass per unit length of the trimmed stream of tobacco carried along by the travelling band 2.
  • This current may be utilized for controlling the servomotor 14 by resorting to known methods and devices comprising an amplifier 26, an integrator 27 and an indicator or measuring instrument 28. Finally, across the output terminals of the indicator 28 a voltage is available which is zero when the discrepancy between the average density of the stream and the desired average density is null, and positive or negative according as this average density is higher or lower than the desired average density.
  • Contactors 29, 30 are energized through the circuit fed with the current from the measuring instrument 28.
  • This circuit comprises a biased relay 35 actuating a contact arm 36 to make contact with a contact 37 or a contact 38.
  • This relay 35 is energized only when the voltage across its terminals is higher than a predetermined value, for no correction in the vertical position of the bed plate 13 is required unless the difi'erence between the real and the desired average mass per unit length exceeds a permissible value.
  • This circuit also comprises a switch 39 actuated by a cam 40.
  • This cam is driven continuously from the main shaft of the machine (not shown).
  • the cam 40 accomplishes one revolution in about two seconds, and the switch 39 is closed during one second.
  • the switch 39 closes the circuit of the measuring instrument; if the voltage across the terminals A and B is zero or lower than the minimum value necessary to energize the relay 35, no current flows through the windings of contactors 29 or 30, and the motor 14 is not energized. If the voltage across the terminals A and B is positive, (for example because the average mass per unit length of the cigarette rod has become higher than the desired average) and exceeds the minimum value required for energizing the relay 35, the latter will actuate the contact arm 36 to make contact with the fixed contact 37, the contactor 29 being thus energized to operate the tandem levers 31 and 32, and the motor 14 will rotate in the direction which causes the bed plate 13 to move upwards.
  • the relay 35 actuates the contact arm 36 to make contact with the fixed contact 38 and the other contactor 30 becomes energized, thereby causing the motor 14 to rotate in the direction which causes the bed plate 13 to move downwards.
  • the stream originally formed on the conveyor band 2 is deeper than required, and as this stream approaches the trimming device, its uppermost part extends above the upper level of the guide members 24 and constitutes surplus tobacco which is removed by the trimming device, which thus trims the stream to the desired cross-sectional size.
  • the bed plate 13 by moving the latter towards and away from the trimming device in the manner described above, it is possible to cause relative movement, laterally of the stream, between the stream and the trimming device.
  • Such vertical adjustments of the bed plate 13, which supports the band 2 have the effect of varying the cross-sectional size of the channel through which the stream moves past the trimming device, and therefore of varying the crosssectional size to which the stream is trimmed by the cutters 12.
  • the means for efiecting these adjustments namely the trimming device, can be located very close to the measuring device. It will be seen that this arrangement enables corrections to be made very much more rapidly than in a case where, for example, corrections are effected by altering the rate of feed of tobacco from the hopper of the machine, since in the latter case, considerable time elapses between the moment when the alteration of the rate of feed is made, and the moment when a corresponding alteration results in the tobacco stream or filler in the region where the measurement takes plate.
  • the present invention makes it possible to reduce the distance between the place where the measurement of the stream occurs, and the place where the adjustment of the cross-sectional size of the stream takes place, and consequently to reduce the time required for such adjustment to become etfective.
  • the measuring device may he so located as to measure the stream as the latter approaches the trimming device, instead of being located as shown in the accompanying drawings.
  • a tobacco-manipulating machine such as a continuous rod cigarette-making machine
  • means to form and feed forwardly a tobacco stream whose cross-sectional size is greater than required a trimming device to remove surplus tobacco from the stream
  • a measuring device arranged to measure the quantity of tobacco in a part of the stream passing said measuring device
  • ad usting means responsive to measuring operations by the said measuring device to cause relative movement, laterally of the stream, between the stream and the trimming device, so as to vary the cross-sectional size to w an is trimmed.
  • Apparatus as claimed in claim 1 comprising a conveyor by which the stream is conveyed, and wherein the said adjusting means comprises means to move laterally the said conveyor, so that a part of the stream is moved towards and away from the trimming device.
