Definitions

  • the present invention relates to an apparatus for applying stamps onto containers for smoking articles, comprising:
  • an apparatus of the type in question uses hot glue to fix the stamp to the container.
  • a limit to the operating speed of the apparatus is constituted precisely by the time required for the hot glue to dry, to achieve a stable fixing between the stamp and the container.
  • the most critical connection is that which regards the folded portion of the stamp, as this portion is capable of expressing a certain elastic return, which tends to make it detach from the container if the glue has not reached a sufficient degree of drying.
  • the present invention aims to improve the indicated solution, in particular to increase its production capacity, while at the same time guaranteeing an optimal quality of the manufactured product.
  • the present invention also relates to a smoking article packaging system according to claim 11, and a method for applying stamps onto containers for smoking articles according to claim 12.
  • the present invention relates to an apparatus for applying stamps onto containers for smoking articles.
  • FIG. 4 represents an example of a packet of cigarettes, indicated as a whole with the reference number 100, on which a state stamp 110 is applied.
  • the stamp 110 is folded as an L, so as to identify a first portion 110A, which is applied to the upper face 102 of the packet 100, and a second portion 110B, which is fixed to the side face 104 of the packet 110.
  • the two portions 110A, 110B are fixed to the two faces 102, 104, respectively, of the packet 100, by means of a layer of hot glue 105.
  • the packet 100 is of the hinged cover type and comprises: a container that contains the group of cigarettes (possibly wrapped in a wrapper), wherein the group of cigarettes protrudes from an upper opening of the container; a cover that is hinged to the container and is movable between an open position, wherein it allows access to the group of cigarettes, and a closed position wherein it prevents access to the group of cigarettes.
  • the apparatus described here operates to apply and fix the stamp 110 onto the packet 100 in the folded condition indicated above.
  • the apparatus described here comprises a unit 20 for transporting the packets 100 according to a continuous movement along the advancing direction Y.
  • the unit 20 comprises a conveyor belt which advances the packets 100 along the advancing direction Y.
  • the apparatus 10 comprises, arranged in succession along the transport unit 20, a unit 40 for applying glue (preferably of the hot glue-type) onto the packets 100, a unit 60 for supplying the stamps 110, and a unit 80 for folding the stamps 110 applied onto the packets 100.
  • glue preferably of the hot glue-type
  • the packets 100 are arranged so as to turn the faces 102 and 104 frontally and upwards, respectively, so that they are accessible to the units 40, 60, 80 of the apparatus 10.
  • the unit 40 is designed to deposit hot glue on the faces 102, 104 of the packet 100.
  • This unit may be of the conventional type and use, for example, glue dot dispensing means.
  • the unit 40 - or an additional fixing unit - may deposit the glue on the inner face of the stamp 110 instead of at least one of the faces 102, 104 of the packet.
  • the unit 60 for supplying the stamps 110 is designed to apply the stamp on the face 104 of the packet according to an arrangement so that the stamp 110 protrudes frontally from the face 104 with a portion that will constitute the portion 110A described above.
  • the portion of the stamp which instead adheres to the face 104 constitutes the portion 110B.
  • the supply unit 60 may be of the conventional type.
  • this unit 60 comprises a drum 62 rotating around a horizontal axis I1, with which a hopper 64 is associated, intended to contain a stack of stamps 110.
  • the drum 62 picks up the individual stamps 110 in succession by means of suction means associated therewith and transfers them onto the packets 100 which pass under it.
  • the unit 80 is designed to fold the protruding portion 110A of the stamp 110 against the face 102 of the packet 100.
  • FIG 2 illustrates an example of the folding unit 80.
  • the unit 80 comprises a drum 82 rotatable around a horizontal rotation axis 12, on which a plurality of folding members 84 are mounted so that they can be operated according to a composite movement in the plane orthogonal to the rotation axis of the drum 82.
  • this plane is parallel to the advancing direction Y of the transport unit 20.
  • the folding member 84 is - in particular - operated according to a movement approaching the face 102, during which it intercepts the portion 110A of the stamp 110, and folds it against the same face 102, a subsequent movement wherein it accompanies the advancement of the packet along the direction Y, continuing to press the portion 110A of the stamp against the face 102, and finally a movement away from the face 102 and from the portion 110A of the stamp 110 fixed on it.
  • Figures 3A, 3B , 3C illustrate these three successive steps of the operation of the folding member 84.
  • the folding member 84 has an L-shaped longitudinal profile and is intended to engage the portion 110A of the stamp through its transverse end 84A.
  • the folding member 84 will initially engage the portion 110A of the stamp with its face 84' ( Figure 3A ), and subsequently with the adjacent face 84" when it presses the portion 110A against the face 102 of the packet ( Figure 3B ).
  • the means for actuating the members 84 may be of the conventional type, so that they will not be described in detail here in order not to make the present description more complicated.
  • they can include cam means arranged to actuate the folding members 84 in the manner indicated above, by effect of the rotational movement of the drum 82.
  • the folding unit 80 comprises a pneumatic system 120 arranged to blow a gas blow, preferably air, against the portion 110A of the stamp so as to press it against the face 102 of the packet.
  • a gas blow preferably air
  • the emitted blow is compressed air, for example at 4 bar, at room temperature.
  • the pneumatic system 120 comprises a distribution module 122, mounted centrally on the drum 82 and connected to a source of compressed air - not illustrated - and a plurality of ducts 124, which connect the various folding members 84 to the distribution module 122.
  • inner passages - not illustrated - are obtained in the folding members 84 which are placed in communication with the ducts 124, and lead onto the faces 84" of the members 84 through openings 128.
  • the ducts 124 are preferably extendable and connected in a rotatable way to the distribution module 122 and to the folding members 84 in order to be able to follow the folding members in their movements.
  • the ducts 124 are flexible and have a superabundant length, precisely to be able to follow the movements of the folding members 84.
  • the blow of air delivered through the opening 128 will hit the portion 110A of the stamp to press it against the face 102 of the packet.
  • the pneumatic system 120 is controlled to blow air during the approaching movement and/or the accompanying movement and/or the moving away of the folding member 84 ( Figures 3A and 3C ).
  • the pneumatic system 120 is controlled to blow air during the approaching movement and the accompanying movement and the moving away of the folding member 84.
  • the time in which the portion 110A of the stamp is pressed against the face 102 is lengthened, compared to the time in which the portion 110A is mechanically pressed against the face 102 by the folding member 84, during its accompanying movement.
  • the apparatus 10 described here solves the technical problem discussed at the beginning of ensuring a stable fixing between the folded portion of the stamp and the corresponding face of the packet, through the combined action of the folding members 84 and the pneumatic system 120.
  • This type of solution allows increasing the operating speed of the apparatus 10 and, therefore, its productivity, due to the fact that the shorter duration of the accompanying movement of the folding members 84, due to the greater speed, is compensated by the action of pressure by blowing air, of the pneumatic system 120.
  • the blow of air generated by the system 120 also performs the function of accelerating the drying of the glue, which is interposed between the portion 110A and the face 102, this further reducing the cycle time necessary to fix the portion 110A to the face 102 of the packet.
  • the blow of air generated by the system 120 has a predefined temperature to favor the drying of the hot glue.
  • a detection unit 90 to detect the presence and/or positioning of the stamps 110 on the packets 100. In the case of absence or incorrect positioning of the stamp, discard means can intervene to remove the defective packet from the conveying line.
  • the apparatus 10 described here may be integrated into a packaging system for smoking articles which has - downstream of the apparatus 10 described - a wrapping apparatus (not shown) for wrapping in outer wrappers - for example, a film made of polymeric material - the packets with the applied stamps.
  • the aforementioned detection unit 90 may be arranged at the downstream wrapping apparatus.
