  The object of the present invention is to provide a method and apparatus which are designed to at least partly eliminate the above-mentioned drawbacks and at the same time are low-cost and easy to implement.

  The present invention provides a method and apparatus as claimed in the attached independent claims or in any one of the claims dependent directly or indirectly on the independent claims. The

  In the following, non-limiting embodiments of the invention will be described by way of example with reference to the accompanying drawings.

  Number 1 in FIG. 1 shows an inner wrapping 3 comprising a sheet 3 ′ (FIG. 9) of heat sealing material wrapped around a cigarette set G to define a packaged cigarette set 4. An apparatus for producing a cigarette package 2 (FIG. 8) comprising an outer container 5 wound around a packaged cigarette set 4, preferably made of thin paperboard, is generally shown.

  More specifically, the sheet 3 'is made of a multi-layer laminate material in which one or more layers comprise a metal material and the other layers comprise a plastic material. A sheet 3 '(FIG. 9) is applied to the substantially U-shaped slit 6 defining an opening in the packaging material 3 and an adhesive surface and is placed over the slit 6 to close the inner packaging material 3. And a patch 7 to be attached.

  Package 2 is substantially the same as the package described in Patent Document 1, which is incorporated herein by reference.

  The apparatus 1 passes along the supply path P and passes through the slit forming station 11, the two pasting stations 12, 13 (FIG. 2), and the control station 14 (FIG. 7). 1) comprises a conveyor 8 (FIG. 2) for supplying a strip 9 of heat sealing material. The pasting station 13 is disposed downstream from the pasting station 12, while the pasting station 12 is disposed downstream from the slit forming station 11, and the control station 14 is downstream from the pasting station 13. Has been placed.

  The apparatus 1 (FIG. 2) further comprises a working unit 15 arranged in the slit forming station 11 for forming the slit 6 in the strip 9 and a pasting station 12 for pasting the patch 7 on the slit 6. Is disposed between the affixing unit 16, the affixing unit 17 disposed at the affixing station 13, and the affixing stations 12, 13 for detecting the presence of the patch 7 on the strip 9. The detection unit 18 is provided.

  In actual use, the strip 9 is cut at a cutting station 10 in order to separate the sheet 3 ′ with patches 7 and slits 6 from the strip 9.

  The device 1 further comprises a central control unit 19 connected to the sensor 20 of the detection unit 18 to activate the affixing unit 17 when the sensor 20 does not detect the patch 7 on the slit 6.

  Providing the pasting unit 17 downstream from the pasting unit 16 allows the apparatus 1 to operate at high speed. In this connection, the application of the patch 7 to the strip 9 is a relatively slow operation, and only one of the application units 16, 17 has a continuous slit 6 when the strip 9 is fed at a high speed. It is important to point out that it is not guaranteed that the patch 7 will be applied properly. Further, the provision of the pasting unit 17 downstream from the pasting unit 16 makes it possible to perform maintenance and inspection without interrupting the production of the cigarette package 2 (cleaning of the pasting unit, strip for supporting the patch 7 in a peelable form). The operator can temporarily stop either one of the pasting units for the reel 39).

  The working unit 15 comprises a roller 21, which roller 21 rotates around its respective axis 22 and rotates around the axis 22 to form a slit 6 and contacts the strip 9. (Not shown).

  Referring to FIG. 7, the control station 14 has a control unit 23 for determining the proper placement of the patch 7 on the slit 6.

  The control unit 23 comprises a detector 24 and an illumination system for illuminating the upper surface 25 of the strip 9 with diffuse light, which illumination system is arranged on both sides of the path P and parallel to the strip 9. Two light sources 26 and a cover 27 (shown by dotted lines in FIG. 7) are provided. The cover 27 is located above the path P and has a downwardly concave surface 28 facing the path P and the surface 25. The light source 26 directs inclined light onto the concave surface 28, which reflects the light to illuminate the surface 25.

  The detector 24 is disposed on the path P and is accommodated in a seat portion in the cover 27.

  By using diffuse light, the detector 24 can detect the edge of the patch 7 even when the patch 7 is substantially the same color as the strip 9.

  The control unit 23 further comprises an illuminating device 29 for directing light on the slit 6 below the path P and passes through the slit 6 to detect the presence of the slit 6 on the strip. Light is detected by detector 24. The support surface S on which the strip 9 extends above the control station 14 has a slot F through which light from the illuminating device 29 passes. The detector 24, the illumination device 29, and the slot F are preferably aligned in the vertical direction.

  The cover 27 is movable to allow the operator to freely approach the control unit 23.

  The control unit 23 further comprises a sensor 30 for detecting the reference element 31 printed on the strip 9.

  Next, the operation of the control unit 23 will be described with respect to the moment when the element 31 is detected by the sensor 30. The light source 26 emits a flash, and an image is acquired by the detector 24 and processed by the central control unit 19, to which the detector 24 is connected (the detector 24 and the central control unit). The connection to 19 is not shown). The central control unit 19 compares the detected value with a reference value and emits an error signal if the detected value does not match the reference value. More specifically, the central control unit 19 compares the position of the edge 32 of the strip 9 with the position of the longitudinal edge 33 of the patch 7 (detected in the two areas L1, L2), and The position of the transverse edge 34 of the patch 7 is compared with the position of the element 31 (detected by the sensor 30).

  In this way, the control unit 23 can accurately determine whether the patch 7 is properly oriented and positioned with respect to the strip 9 in the longitudinal and transverse directions.

  When the detector 24 cannot receive sufficient light that has passed through the slot F, it is displayed that there is no slit 6.

  The conveyor 8 (FIG. 2) comprises a suction belt 35 for feeding the strip 9 through the application stations 12, 13, below this suction belt 36 a suction device 36 (shown in dotted lines in FIG. 2). ) Is arranged. The suction belt 35 prevents the strip 9 from moving across the path P, and at the same time, when the application unit 16, 17 places the patch 7 on the strip 9, it is preliminarily placed in the strip 9. It is ensured that the slit 6 formed is pushed down, thereby ensuring a very accurate application of the patch 7 on the strip 9.

  The accuracy when the patch 7 is applied to the strip 9 is further improved by this unique structure and operation of the application units 16,17.

  The affixing unit 16 (FIG. 3) is a conveyor 38 that supplies the affixer head 37 and a strip 39 that supports the patch 7 in a peelable manner to the affixer head 37 in a direction intersecting the path P. With.

  In actual use, the strip 39 is fed around the blade 40 to separate the patch 7 from the strip 39. The applicator head 37 has a known suction system (not shown) for holding the patch 7 on the perforated bottom surface 41 of the applicator head 37. This surface 41 (FIG. 4) is disposed on the path P, is substantially horizontal, and is substantially parallel to the surface 25.

  The applicator head 37 further emits an air jet through the surface 41 in a direction intersecting the path P. More specifically, the air jet is directed downward in a direction substantially perpendicular to the path P and the surface 25, so that the patch 7 is separated downward from the surface 41, It moves parallel to itself in a nearly vertical direction.

  The pasting unit 17 is almost the same as the pasting unit 16.

  At the cutting station 10, a known cutting assembly 42 (shown schematically in FIG. 1) cuts the strip 9 in order to separate the sheet 3 ′ with the patch 7 and the slit 6 from the strip 9. .

  The apparatus 1 further comprises a known winding assembly 43 (shown schematically in FIG. 1) for winding a sheet 3 'around the cigarette set G to form a packaged cigarette set 4. A sealing assembly 44 for sealing the overlapping portion T of the sheet 3 'wrapped around the cigarette set G.

  The sealing assembly 44 comprises wheels 45 (shown in FIG. 1 as continuous lines and in FIGS. 5 and 6 as dotted lines), while the wheels 45 are in their respective packaged sets. There are several known peripheral seats (not shown), each for receiving 4.

  With particular reference to FIGS. 5 and 6, the sealing assembly 44 further includes two sealing units 46 on opposite sides of the wheel 45. Each sealing unit 46 keeps said portion T of the sheet 3 'in proper overlap with an oscillating magnetic field generator 47 (shown schematically) and a movable member 48 of non-conductive material. And an actuator 49 that moves the movable member 48 to contact the portion T of the sheet 3 '. Generator 47 is maintained in a substantially fixed position.

  The oscillating magnetic field generated by the generator 47 generates heat in a specific area of the sheet 3 'by the sheet 3' containing the metal component.

  In this way, a high-quality seal can be achieved, while the risk of damage to the sheet 3 'and / or the cigarettes (not shown) packaged with this sheet 3'. Reduce the performance.

  This is achieved very simply and at low cost by not moving the generator 47.

  The generator 47 is preferably oil cooled.

  The embodiment of FIGS. 5 and 6 shows two actuators 49 for each sealing unit 46, but alternatively the movable member 48 may be driven by a single mechanical mechanism. It should be pointed out.

  A non-illustrated embodiment of the sealing assembly 44 comprises a conventional sealing unit with heating elements instead of the electromagnetic induction type sealing unit 46.

  The device 1 further comprises a packaging assembly 50 for inserting the package 4 packaged inside the outer container 5.

  More specifically, the packaged set 4 may be inserted inside a preformed outer container 5 or an outer container 5 may be formed around the packaged set 4. As used herein, the expression “inserting a set of cigarettes packaged inside an outer container” includes both of the options described above.

  In a preferred embodiment not shown, a suction compensation chamber for the strip 9 is provided between the application station 13 and the control station 14 and is included herein for reference, for example. It is the type currently demonstrated by the patent document 2 which is.

  In another preferred embodiment not shown, several sensors, each for detecting the presence of an element 31, are arranged along the path P, in which case the central control unit 19 is connected to that sensor. The operation of the assembly and unit of the device 1 is adjusted in response to the detection of.

  The operation of the device 1 will be generally described with respect to the moment when the working unit forms the slit 6. At this point, the strip 9 is continuously fed along the path P to the cutting station 10 through the application stations 12, 13 where the patch 7 is applied to the slit 6 and through the control station 14. The The sheet 3 'is formed at the cutting station 10 and fed through the reject station 51, in which the reject unit 52 removes all of the defective sheet 3'.

  If not, the sheet 3 ′ is fed into the wrap assembly 43, which wraps the sheet 3 ′ around the cigarette set G to form a packaged set 4. Then, the inner wrap 3 is stabilized by the sealing assembly 44. And finally, the packaged set 4 is inserted into the outer container 5.
