Definitions

  • tobacco feeding apparatus comprising a mouthpiece, a first feeding band disposed in a generally vertical plane, a second feeding band cooperating with the first band to force tobacco through the mouthpiece and heating means to increase the heat of the tobacco so that it is cut against the mouthpiece at a desired temperature.
  • the heating means may comprise ducting which together with part of the tobacco being fed defines a closed circuit within which gas can be circulated. There may be provided in the closed circuit a heater for heating the gas, gas circulating means, perforations through which the gas can pass into and out of contact with the tobacco, and gas humidifying means. Insulating means may be provided to retain heat transferred from the gas to the tobacco.
  • a cutting machine which is part of a manufacturing process having a steady flow line should be adaptable to cut constant quantities of tobacco per unit of time. It has in the past been found possible to achieve this by feeding the tobacco to be out onto a feed band moving in a generally horizontal plane. The horizontally moving tobacco is then compressed between the feed band and a further feed band which is arranged to converge on to the first band.
  • British patent application No. 6,733/ 64 there is disclosed a tobacco cutting machine in which the tobacco is fed vertically between two feed hands into the mouthpiece of the machine. This arrangement is such tha t an even feed of tobacco cannot readily be achieved.
  • tobacco feeding apparatus comprising a mouthpiece, a first feeding band disposed in a generally vertical plane, cooperating with the first band a second feed band having a substantially horizontal run on which tobacco is fed, guiding means located above the first band to assist directing the tobacco from the horizontal run of the second hand to a generally vertical direction of feed into the mouthpiece and heating means so that the tobacco is out against the mouthpiece at a desired temperature.
  • the second hand may pass around a roller so as to change its direction from the horizontal run to a generally vertical run, while the guiding means may comprise two driven rolls disposed so that their cylindrical surfaces are in contact with the tobacco being fed.
  • the two rolls may be provided with circumferential recesses so as to intermesh.
  • FIGURE 1 is a section through part of a tobacco cutting machine showing the feeding arrangements.
  • FIGURE 2 is a section along the lines IIII of FIG- URE 1.
  • FIGURE 3 is a diagrammatic representation of part of the apparatus of the tobacco cutting machine.
  • FIGURE 4 is a diagrammatic representation of a further embodiment of feeding arrangements for a tobacco cutting machine.
  • a tobacco cutting machine feed bands 1 and 2 there is shown in a tobacco cutting machine feed bands 1 and 2.
  • the feed band 1 is driven by means of a roller 3 keyed to a shaft 4.
  • the band 1 returns about an idler roller 5 whilst the direction of rotation is as shown by the arrow 6.
  • the band 2 is driven by a roller 7 keyed to a shaft 8.
  • the band 2 passes around two idlers 9 and 10 which are arranged so that there is a horizontal run 11 for this band which is driven in the direction of arrow 12.
  • Tobacco is supplied from a conveyor 16 to the horizontal run 11 of the feed band 2 over a bridge 17.
  • FIGURE 2 Abutting the sides of the feed band 2 are side plates 18 and 19, see FIGURE 2, having their faces provided with perforations 20. Backing on to the side plates 18 and 19 are chambers 21 and 22 respectively. Further chambers 23 and 24 are positioned as shown in FIGURES l and 3 with perforated plates 25 and 26 abutting the tobacco carried on the conveyor 16 and the feed band 2.
  • rolls 27 and 28 Positioned above the feed band 1 are two rolls 27 and 28. As can best been seen in FIGURE 2 the rolls 27 and 28 are rotatable about hollow shafts 29 and 30 respectively.
  • the rolls 27 and 28 are hollow and are provided with recesses 31 which are drilled with a series of holes 32.
  • the shafts 29 and 30 are also provided with holes 33 and are driven by pinions 34 and 35 respectively.
  • a gas supply unit 36 shown diagrammatically is adapted to deliver air, water vapour or steam or any combination of them along a delivery pipe 37 which divides at its end into pipes 38 and 39 feeding the rolls 27 and 28 respectively and which has a branch pipe 40 feeding the chambers 21 and 22.
  • the chambers 23 and 24 are connected by means of a return duct 41 and a branch duct 42 back to the supply unit 36.
  • the supply unit 36 is also provided with a heater which is not shown.
  • the cutting machine feed apparatus can be supplied through the rolls 27 and 28 and the chambers 21 and 22 with an air/Water vapour mixture of required temperature and moisture content directed on to the tobacco being fed therethrough. Controls of known type are included for regulating the quantity of gas flow, temperature and moisture content but are not shown.
  • insulating plates are added. Of these a top plate 43, front plate 44 and a rear plate 45 are shown shrouding in the rolls 27 and 28. Similarly a side plate 46 is shown in FIGURE 1. Other plates to complete the closing in and thus the insulation of the apparatus are provided but are not shown.
  • the feed bands 1 and 2 may be maintained at the required temperature by means of heaters 48 and 49 fitted to their return runs.
  • a temperature and moisture content considered suitable for the quantity and quality of the tobacco being fed by the conveyor 16 is selected for the quantity chosen of the air/water vapour mixture delivered by the supply unit.
  • the quantity of tobacco delivered by the conveyor 16 is similarly chosen and controlled by means of proven ability.
  • the air/water vapour mixture yields up part of its heat and part of its moisture to the tobacco and the expended mixture is sucked back through the holes in the perforated plates 25 and 26 to be returned to the supply unit 36 where it is reheated and reconditioned.
  • the heat and moisture in the tobacco is retained by the insulating plates such as those shown by the reference numbers 4346 and by the heaters 48 and 49' until after the tobacco passes through the mouthpiece 13 against which it is cut by the knives 14.
  • This retention of heat and moisture allows the tobacco to remain supple and soft and thus minimises any tendency for the action of the knives to cause undesirable breakage.
  • rolls 27 and 28 which are arranged to have the same peripheral speed. This peripheral speed is the same and is in the same direction as the movement of the top of the tobacco carpet as it changes direction.
  • the rolls 27 and 28 help to guide the tobacco into its vertical movement and to prevent any possibility of falling which would result in loss of control and, of course, in the cutting machine having an irregular output.
  • FIGURE 4 A further embodiment is shown in FIGURE 4 in which like numbers refer to like parts.
  • 1 and 2 are feed bands of which 1 is driven by means of a roller 3 keyed to a shaft 4.
  • the band 1 returns about an idler roller whilst the direction of rotation is as shown by the arrow 6.
  • the band 2 is driven by a roller 7 keyed to a shaft 8.
  • the band 2 passes around two idlers 9 and which are arranged so that there is a horizontal run 11 for this band.
  • ducts 112 and 113 Abutting the sides of the bands 1 and 2 are two ducts 112 and 113.
  • the duct 112 is an inlet duct while 113 represents a return duct.
  • the sides of both ducts 112 and 113 abutting the bands 1 and 2 are provided with small perforations 114 through which a gas can diffuse.
  • Both ducts 112 and 113 are shaped so that the perforated portion abuts part of the horizontal run 11 of the bands 1 and 2 and part of the vertical or near vertical run between the bands 1 and 2.
  • Fixed near the top of the duct 112 is a hinge pin 115 whilst a similar hinge pin 116 is fixed to the return duct 113. Pivoting on the hinge pins 115 and 116 is a plate 117.
  • a transducer 129 of known design which is capable of transmitting a signal according to the position of the plate 117 on the pin 116.
  • FIGURE 4 the ends of the ducts 112 and 113 are shown broken off at 118 and 119 respectively.
  • a chain line 130 passing through diagrammatically shown boxes 120, 121, 122 and 123.
  • the box 120 represents a fan; 121 is a humidity measuring device; 122 is a humidity controller; while 123 is a combined thermostat and heater.
  • the direction of circulation of the gases is indicated by arrow 124.
  • a line 125 is shown entering the fan 120 and is intended to indicate the entry of make-up air.
  • a water line 126 is shown connected to the humidity controller 122.
