Definitions

  • the invention relates to a cigarette turning device for preferably manually rotating and compressing tobacco rolls for cigarettes with two rotatable rolls spaced apart by less than the diameter of the tobacco roll to be produced, the axes of which run parallel to one another, one of which rolls or displaces relative to the other is pivotable and runs over an endless belt, the length of which exceeds the circumference of the roller system by approximately twice the circumference of the tobacco roll to be produced and the width of which corresponds to the length of the rollers, the belt being frictionally applied to the rollers under tension.
  • cigarette smokers prefer not to consume industrially manufactured cigarettes for taste, cost or other reasons, but to shape the loose tobacco into a roll and to add a cover sheet and, if necessary, a filter to a cigarette. Since the formation of the roll requires great skill and inexperienced people in particular often do not achieve the desired shape, cigarette rolling devices are widely used which facilitate the manual rotation of the tobacco rolls.
  • the usual cigarette turning devices consist of two axially parallel, rotatable rollers which correspond in length and preferably also in diameter to the cigarette to be shaped.
  • a belt runs over both rollers, for example made of a flexible plastic or leather, the width of which corresponds to the length of the rollers and the ends of which are either free or connected to one another in such a way that an endless belt is formed which surrounds both rollers.
  • the length of the endless belt exceeds the circumference of the roller system approximately in the range between 1.5 and 2 times the circumference of the tobacco roll to be produced, the belt length being adapted to the arrangement of the rolls, specifically their circumference and minimum distance.
  • Such a device is described for example in DE-B-2 23 52 211.
  • the device works as follows. Due to the length of the belt, an indentation can be introduced into its course between the rollers, into which the tobacco to be rotated is introduced, if necessary after a filter has been inserted beforehand. At least one of the rollers is displaceable in the direction away from the other roller, for example in an elongated hole, or is pivotably fastened on a lever, so that the base of the indentation can be narrowed and the tobacco can be largely enclosed.
  • An endless belt is stretched taut due to its limited length and therefore runs frictionally over the rollers, with the result that when a train on the belt or the rotation of one roller also the other roller and the enclosed tobacco are set in rotation.
  • both rollers and the tobacco enclosed between them correspond to deflection rollers around which the belt runs under tension.
  • a roll is rotated, consolidated and compacted, the shape of which is precisely determined by the dimensions of the rotating device.
  • the tobacco is prevented from falling out by the wall of the housing of the device which is directly adjacent to the ends of the rollers and is generally made of sheet metal.
  • the tobacco roll is provided with a cover sheet, for example by guiding it between the belt and the tobacco roll towards the end of the turning process.
  • rotary devices customary in the prior art can only be used for the production of cylindrical cigarettes.
  • many smokers prefer cigarettes with a conical shape towards the mouthpiece in order to increase the amount of tobacco and to extend the burning time.
  • a conical shape of the cigarette is also advantageous for health reasons, since the glowing area of the cigarette, and thus the place where harmful harmful substances are produced, is at a greater distance from the mouthpiece over a longer portion of the burning period. This significantly extends the path of inhaled smoke through the tobacco column, and a larger proportion of the pollutants is filtered out.
  • FR-A-1 2 558 042 Another cigarette rolling device is known from FR-A-1 2 558 042. It has a housing in which two conical or frustoconical rollers are arranged, over which a band is guided, so that a pocket is formed. With such an arrangement, conical cigarette or tobacco rolls should be able to be produced. However, it has been shown that such a device is difficult to handle and does not provide satisfactory results with regard to the taper of the tobacco rolls.
  • the present invention has for its object to provide a cigarette rolling device with which easy to handle and with good results conical tobacco rolls can be produced.
  • the above object is achieved, starting from a cigarette turning device, as is known for example from DE-B-2 23 52 211, in that the length of the endless belt parallel to the axes of the rollers increases continuously.
  • a band of the device designed according to the invention preferably has an approximately cylinder jacket to trapezoidal shape in the separated state. Conversely, it can be made by connecting the sides of an approximately cylindrical or trapezoidal piece of flexible material, which run at an angle to the mutually parallel edges.
  • the circumference of the endless belt is still approximately the sum of the circumference of the roller system and twice the circumference of the tobacco roll to be produced. However, the latter now takes place parallel to the axes of rotation of the rollers continuously in one direction, in particular linearly, to. If the belt is otherwise stretched over both rollers, an indentation is created between them, the depth of which increases in a direction parallel to the axes.
  • this indentation is filled in a conventional manner with tobacco, the rollers are moved towards one another in an elongated hole or a hinge, and the belt is set in motion, a roll of the desired, conical shape is thus created.
  • a frictional belt path over the rollers which is created by the elastically compressed tobacco pulling the preferably also elastic bath against the roller surface. This ensures that when the rollers are rotated, which can also be done by a drive or a crank, the length of the strip which is fed into and removed from the indentation is the same on both edges of a roller. In this way, an inclined position of the belt is avoided and the different length of the indentation along the roller axes is maintained.
  • the advantageous consequence is a safe function of the device in the desired manner.
  • the essential feature of the above-described method for rotating and compacting a conical tobacco roll, in deviation from the manufacture of a cylindrical roll, is that the depth of the indentation in the band increases continuously in one direction parallel to the roll axes. Furthermore, a frictional fixation of the belt on the rollers is required before both are set in motion so that the different length of the indentation along the axis is maintained during the turning process. If these requirements are ensured, the method can also be carried out with devices which differ in their construction from the embodiment described above. For example, it is conceivable to use a rotating device with an open-ended belt, the frictional engagement being achievable by pressure rollers acting against the rollers. An alternative is the form fit between gear-like rollers and an elastic toothed belt interacting with them as a band.
  • FIG. 1 shows a side view of a cigarette turning device, with parts of the housing 1 and the cover 2 being omitted.
  • the device consists in its basic structure of two rollers 3, 4, which are each rotatable about an axis 5, 6 and over which an endless belt 7 runs, the length of which exceeds the common circumference of both rollers 3, 4, so that one between them Indentation 8 can be introduced.
  • the right roller 4 is attached with its axis of rotation 6 not directly to the housing 1, but to a lever 9, which in turn is pivotable about the axis of rotation 10.
  • the cover 2 is fastened to the lever 9, the purpose of which is, in particular, to provide the user with a suitable handle on the component which is only a few centimeters in size in accordance with a cigarette length.
  • the lever 9 pivots upward, so that the distance between the rollers 3, 4 increases and the indentation 8 between them is easily accessible. It is filled with tobacco, if necessary after inserting a filter, and the rollers 3, 4 are subsequently brought together again by pivoting the cover 2 and lever 9. Due to the encompassing of the tobacco 11, the belt 7, which is made of, for example, fabric-reinforced plastic, is pulled frictionally over the rollers 3, 4. By rotating the freely accessible area of the belt 7 running over the roller 4, the two rollers 3, 4 and the enclosed tobacco 11 are thus set in rotation. The tension of the tape causes a firm, sufficiently dense roll of tobacco of a given shape to arise during this process.
  • Figure 2 shows a vertical section through the device in the region of the shaped roll of tobacco 11. It can be seen that the depth of the indentation 8 increases linearly along the axis 5 of the roller 3, as can be achieved, for example, by two edges of one approximately trapezoidal strips of material are connected to form an endless band. As a result, a roll of the desired conical shape.
  • the frictional course of the belt 7 ensures that the removal and tracking of the belt 7 from the indentation 8 is the same along the entire length of the rollers 3, 4, so that the differences in the depth of the indentation 8 are retained. However, this does not necessarily mean that their average length remains constant, which rather generally decreases slightly as the tobacco 11 is gradually compressed.
  • a cigarette rolling device is described with which conical cigarettes can be rotated in a simple manner, preferably by hand.
