Definitions

  • the invention relates to a device applicable when uniting cigarettes with mouthpiece attachments, for folding down the flaps of a connecting strip of desired material around the abutting points of cigarettemouthpiece attachment assemblies lying on a conveyor device moved perpendicularly to the longitudinal axis of the cigarettes, for example on a drum, and subject to. suction action.
  • Two known folding-down methods may be distinguished for folding down the connecting strips about the abutting points between the cigarette and the mouth-piece attachment, namely: firstly, folding down during the movement of the cigarette and mouthpiece attachment in the direction of the longitudinal axis of the cigarette (string processes) or secondly transversely thereto, in which groups of cigarettes and mouthpiece attachments are moved on a conveyor device perpendicular to the longitudinal axis of the cigarettes.
  • the cigarettes are withdrawn in known manner firstly in pairs, for example from a storage device, and fed to a drum in mutually spaced condition and a mouthpiece attachment of double length is introduced between both cigarettes, wherein the mouthpiece attachment is normally withdrawn from a storage device as a continuous piece of six-fold length and is divided twice before it is transferred.
  • the group of cigarettes and mouthpiece attachments are then moved to a feed device and receive a connecting strip coated with adhesive, at a station provided. for this purpose.
  • This connecting strip is folded around the abutting points conveniently on a further feed device, for example a drum; the hold ing of the individual parts being generally effected by air (vacuum).
  • the cigarette-mouthpiece attachment assemblies are disposed together with the connecting strips in grooved recesses on the periphery of a rotary drum, in such a way that the centre cross section of each assembly is located on the level of the pitch circle of the drum driving wheel disposed coaxially thereto (for example a spur wheel).
  • the connecting strip For the purposes of folding down the connecting strip the assembly is moved out of the pitch circle.
  • the device is so constructed that the cigarette and the mouthpiece remain in the pitch circle but a special striker device is moved over the assembly in the longitudinal direction of the cigarette so that with this device difficulties are encountered in laying the connecting strip evenly and flatly about the abutting points, which has for its result that firstly the connection between the cigarette and the mouthpiece attachment is not satisfactorily effected and secondly that also the appearance of the cigarette is adversely affected.
  • a flap is laid flat about the abutting points to enclose the connecting strip about the cigarette-mouthpiece assembly transversely to the longitudinal axis of the cigarette and to shift the assembly out of the pitch circle, while for the second flap the folding disc provided for this purpose does not engage and press down the flaps according to the curvature of the diameter of the cigarette and in consequence around the cigarette, but only engages the flaps at its outer part.
  • the folding disc provided for this purpose does not engage and press down the flaps according to the curvature of the diameter of the cigarette and in consequence around the cigarette, but only engages the flaps at its outer part.
  • the object of the invention is in the first place to reduce as much as possible the loss of tobacco from the ends of the cigarette and secondly to fold down the connecting strip completely and firmly at the abutting points.
  • This is obtained according to the invention.
  • the folding device is arranged and moves on, a drum in a preferably radial direction with continu ous movement of the drum, and folds down the connecting: strip perpendicularly to the cigarette axis about the cigarette-mouthpiece attachment assembly, the centre cross section of which, from the receiving point to the delivery point of the assembly, lies on the drum at the level of the pitch circle of the drum driving gear wheel lying coaxially thereto, said gear wheel being for example a spur gear wheel.
  • the folding elements of the folding device move around the periphery of the cigarette and against the connecting strips which are applied at a preceding position on. the cigarettemouthpiece attachment assembly; at the same time retaining pins or the like press on the cigarette from the opposite side.
  • the folding elements follow the curvature of the cigarette and apply first one flap and then the second flap around the abutting points.
  • the retaining pins are already separated from the cigarette-mouthpiece attachment assembly when the folding elements approach one another.
  • Fig. 1 shows a folding drum with a feeder drum, counterdrurn, cutting device and take ol'f belt, but without the folding down device, in diagrammatic side view,
  • Fig. 2 is a partial section of the folding drum according to Fig. l but with the folding down device and the counterdrum in side view and on an enlar ed scale.
  • Fig. 3 is a diagrammatic view showing one groove of the supporting drum with two cigarettes and the mouthpiece unit located between them and one-part folding elements, seen in the direction of the arrow III in Fig. 2,
  • Figs. 4 and 5 show other embodiments of the folding elements
  • Fig. 6 is a diagrammatic view of another folding device.
  • a rotary drum 2 (folding-down drum) is mounted on a shaft 1 and on its periphery there are grooved recesses 3 running parallel to the shaft 1.
  • a plurality of radial passages 4 extend from the bottom of each recess 3 to a bore 4 extending axially beneath the recess 3, and said axial bore 4' which is closed at its ends communicates through a radial bore 4" with a segmental hollow space forming a suction chamber 5 within the drum 2.
  • suction chamber 5 is in turn connected for example by a suction pipe 6 and a bore 7 through the shaft 1 with a suction device of known type.
  • Two cigarettes 8 are disposed non-rotatably for example in the recess 3 (see Fig. 3) and between them is a double-length mouthpiece assembly 8a for each two cigarettes together with a connecting strip or adhesive tape 9 (see Figs. 1 and 2) which projects in V-shaped manner from the recess 3.
  • the cigarette-mouthpiece attachment assembly 8, 8a is fed to the folding drum 2 together with the connecting strip 9, in the present embodiment Fig. 1 from a drum 10 (feeder drum) on a shaft 11.
  • a further drum 13 is mounted on a shaft 12 parallel to the shaft 1, which drum embodies two end walls the spacing of which is greater than the length of the folding elements and 36 and which are connected one with the other by means of spacer rods 14.
  • spacer rods 14 (holding pins) run parallel to the shaft 12 and during operation, press against the cigarettemouthpiece attachment assembly 8, 8a disposed in the grooves 3.
  • gear wheels 15, 16, 17 are fixed to the shafts 1, 11 and 12 which gear wheels engage one with the other and contact one another at their pitch circles at the level of the mid-point of the assembly 8, 8a. While the assembly 8, 8a is connected with the suction chamber 5, the connecting strip 9 on the folding drum 2 is laid against the assembly by means of a folding device which will be described further below. At the points of the drum where suction is not exerted there is located a solid segment 5' which stops the flow of air.
  • the folding device is constructed as follows: for each groove 3 of the drum 2 there is provided a folding device consisting of two radially movable folder carriers.
  • One folder carrier 18 has at its outer end a pivot 19 about which a folding element 20 with rounded head 21 can rotate.
  • a torsion spring 60 which tends to rotate the folding elements 20 continuously towards the assembly 8, 8a.
  • a pin 22 is secured to the folder carrier 18, said pin forming a pivot for a lever 23 which is mounted on a shaft 24 for example by means of clamp screws 25.
  • the lever 23 has at its forward end a slot 26 which serves for introduction of the pin 22.
  • a second lever 27 is mounted on the shaft 24 and carries a roller 28 which rolls on a stationary cam track 29 of a cam disc.
  • a tension spring 30 is secured to the folder carrier 18 which tends to draw the latter inwardly along a shaft 31 located adjacent it.
  • the folding element serves to move one flap of the connecting strip 9 over the abutting points 33 of the assembly 8, 8a following the curvature of the assembly (Fig. 3).
  • ing element 36 is rotatably supported by a pivot 35 on the folder carrier 34.
  • a torsion spring is also located about the pivot 35 which tends to urge the fol-ding element 36 constantly inwardly.
  • a lever 38 of the folder carrier which is supported on the shaft 31 moves relative to a pin 37 on the folder carrier 34.
