Description

The invention relates to a device for producing packages for cigarettes, the packages having a group of cigarettes as package contents and wherein the group of cigarettes is encased in an inner wrapper to form a cigarette block, and wherein the packages may optionally have a collar, and wherein the packages are an outer wrapper have, which is formed from at least two separate blanks and in which the cigarette block is accommodated, along a packaging line of the device units are arranged to form the packs, in particular cigarette turrets, folding turrets and dry turrets, which are interconnected by transport paths, according to the preamble of Claim 1.

Furthermore, the invention relates to a corresponding method according to the preamble of claim 16.

Conventional packages for cigarettes consist essentially of a group of cigarettes, which is wrapped in an envelope (inside) of packaging material, such as Stanniol, (cigarette block) and an (outer) wrapping of another packaging material. Optionally, a so-called collar may be part of the package. Depending on the type of package, solid or rather flexible packaging material is used as the material for the outer wrapping. For example, comes in hard packs such as hinge-lid packs usually thin cardboard as a material for the outer wrapping are used, whereas in flexible packs flexible materials such as paper, foil or the like are used. Further customary is an additional wrapping of the pack in a film such as cellophane, polypropylene, etc.

The decades so far usual elements of a pack for cigarettes made numerous variants of such packs, in particular the cross-sectional shape, the shape of the pack edges, the shape of pack walls, etc. has been varied in order to offer the market always new packs.

One trend is to abandon the usual limitation to the known elements of a pack for cigarettes in order to construct complex package variants. Examples of such packages are EP 2 325 093 A1 refer to. A special feature is that the package is formed from two blanks, which are arranged in this case according to the principle of slide-and-shell. Through a window in the outer pack, the consumer can move an inner pack and thus open the pack. Both the outer package and the inner package are made of a relatively rigid packaging material. A look at the two blanks according to Fig. 2 or 4 indicates that these differ significantly from conventional blanks for cigarettes and can not be processed on conventional packaging machines.

Proceeding from this, the object of the invention is to further develop known packaging machines in such a way that even complex blanks for packs for cigarettes can be processed.

To achieve this object, a device according to the invention has the features of claim 1. It is therefore provided that outside the packaging line further units are arranged for processing the blanks for the outer package, and that the units are connected via transport paths for the at least partially processed blanks with the packaging line, for feeding the blanks to the aggregates of the packaging line.

Further advantageous embodiments of the device according to the invention can be found in the dependent claims and the description, moreover.

Of importance is also a glue unit for applying glue to the blanks. The sizing station comprises a contact application station for transferring glue to a transfer member, preferably a transfer roller, the transfer member being rotationally driven and abutting the blanks on the underside to transfer the glue thereon, preferably the adhesive is a pressure sensitive adhesive ( pressure-sensitive adhesive), in particular a pressure-sensitive hot-melt adhesive, is, and wherein the glue is preferably applied to a peripheral surface of the transfer roller, which is preferably siliconized. This glue unit can also be used independently of the device described. In this respect, if necessary separate protection is claimed for the arrangement or construction of the glue station.

A method according to the invention has the features of claim 16. Further preferred details are given in the description otherwise.

The invention will be explained with reference to a part of a cigarette packaging machine. The object of the packaging process is therefore a (cigarette) pack 10. Optionally, it may also be a bundle pack for cigarettes.

The packs 10 to be produced on the machine include at least one cigarette block 11 as package contents. The cigarette block 11 comprises a group of cigarettes (cigarette group) in a predetermined formation, which is surrounded by a wrapping of packaging material, for example of stanniol.

The package contents or cigarette block 11 is received in the (complex designed) package 10. The box-like package 10 is formed from two separate blanks which together provide the package 10. It is an inner blank 14 on the one hand and an outer cut 15 on the other. In the present embodiment, the folded inner blank 14 forms a receptacle for the cigarette block 11 and with this an inner package 12. The folded outer panel 15, however, forms an outer package 13 as an outer envelope in which the inner package 12 is arranged and in the manner of a shell-and-slide package is displaceable, for opening and closing the package 10. However, the invention is not limited to this type of package.

Furthermore, the package 10 may have a collar, which is missing in the embodiment shown. The collar can be arranged as usual in hinge-lid packs, or as a reinforcement in the area of the cigarette block 11 By definition, however, the collar does not count toward either the inner package 12 or the outer package 13, but is a separate part that may optionally be present.

For reasons of clarity, the machine will be described in sections below with regard to construction and mode of operation. Corresponding headings are used to outline the description of the embodiment, but are not limitations.

overview

With reference to Fig. 1 First, the essential areas of the machine are called and explained in detail below.

The machine has a (central) continuous packaging line 16 along which stations and units for producing the package 10 are arranged. In the present case, the packaging line 16 extends from a cigarette turret 17 to a group of dry turrets 18, 19. It is understood that in other cases the packaging line 16 may also be equipped with other units defining the beginning and end of the packaging line 16 ,

Within the packaging line 16, the aggregates of the machine are arranged consecutively, so that the package 10 is produced in successive processing steps. The packaging line 16 may be substantially straight as in the present case. However, it is also conceivable that the packaging line in the course (angled) kinks, pivots or runs at different height levels.

• Zigarettenrevolver 17,
• Zigarettenbahn 20,
• Faltrevolver 21 für Innenzuschnitt 14,
• Leimaggregat 22,
• Packungsbahn 23,
• Faltrevolver 24 für Außenzuschnitt 15,
• Leimaggregat 25
• Trockenrevolver 18, 19.

In the present case, the following aggregates follow one another within the continuous packaging line 16:

• Cigarette turret 17,
• Cigarette web 20,
• Folding turret 21 for inner blank 14,
• Glue unit 22,
• Packing Railway 23,
• Folding turret 24 for external cut 15,
• Glue aggregate 25
• Dry turret 18, 19.

It is understood that in practice further units may belong to the packaging line 16, the representation and mention of which is omitted in the present case for reasons of clarity.

A special feature is that outside the packaging line 16 more units for processing the inner blanks 14 and outer panels 15 are arranged. These units are arranged in the present case at a distance next to the packaging line 16, wherein transport paths lead to the packaging line 16 in order to feed the partially processed blanks to the packaging line 16.

Section II - Education Cigarette Block and Folding Interior Cutting

Starting from a cigarette magazine, not shown cigarettes are inserted with a slide 29 in pockets of the cigarette turret 17 and pushed out after partial circulation of the cigarette turret 17 as a cigarette group and conveyed along the cigarette web 20.

During the transport of the cigarette group along the cigarette web 20, the groups of cigarettes are each wrapped in an inner wrapper, which is fed as Stanniolbahn 28 above the cigarette web 20 and placed in a conventional manner around the groups of cigarettes to form cigarette blocks 11th

The cigarette blocks 11 are inserted by means of a conventional slider 29 in pockets of the folding turret 21 for the inner blanks 14. The inner blanks 14 are then folded around the respective cigarette blocks 11 and pushed out of the folding turret 21. Here are in the usual way side tabs of the inner blanks 14 from the side, in the area of a subsequent to the folding turret 21 cardboard web 30 with Help glue unit 22 glued and moved over not shown folding switches in the plane of narrow side walls and connected there with other side lobes.

A special feature is the preparation and feeding of the inner blanks 14 to the folding turret 21st

The inner blanks 14 are held ready as a stack in a blank magazine 31 and individually removed on the underside from the blank magazine 31 and deposited in a transport track 32.

The transport path 32 in this case runs parallel to the packaging line 16 and at a distance therefrom.

The transport path 32 is adjoined by a further transport path 36, which runs transversely to the transport path 32 and the packaging line 16 and supplies the inner blanks 14 to the folding turret 21.

The transport path 32 is formed by a plurality of conveyor belts 33, 34, which are parallel to each other and directed to the longitudinal direction of the transport path 32.

The inner blanks 14 are at a distance from each other flat on the top or the upper strand of the horizontally extending conveyor belts 33, 34 and are directed with their longitudinal extent transversely to the transport direction.

The inner blanks 14 are held in the transport path 32 by holding means in the form of cams 35 which rest against the inner blanks 14 in the region of side edges thereof. Preferably, the inner blanks 14 are held in the transport direction and transversely thereto by cams 35. The cams 35 are formed on the conveyor belts 33, 34. The cams 35 of outer conveyor belts 34a, 34b hold the inner blanks 14 only transverse to the longitudinal direction of the transport path 32, whereas the cams 35 of inner conveyor belts 33a, 33b hold the inner blanks 14 only in the longitudinal direction of the transport path 32.

The conveyor belts 33, 34 have a different length in the transport direction, wherein outer conveyor belts 34a, 34b are shorter than inner conveyor belts 33a, 33b and at a distance before a transfer device 47 ends, so that the inner blanks 14 only through the cams 35 of the inner conveyor belts 33a , 33b are held in the longitudinal direction of the transport path 32 and can be pushed onto the transport path 36 transversely to the transport path 32.

During the cyclic transport of the inner blanks 14 along the transport path 32, the inner blanks 14 are subjected to successive processing steps. Among other things, the interior blanks pass through the following folding stations and glue stations:

First, lateral folding tabs 39 of the inner blanks 14 are erected by means of folding stems 37 arranged on both sides along the transport track 32 and then applied to certain areas of the upper side of the inner blanks 14 by means of glue units, preferably hot-melt glue, arranged above the transport track 32.

The folding tabs 39 are folded in the next processing step by both sides of the transport path 32 arranged, movable folding members 40 and bonded to the inner panel 14.

By subsequent pressure rollers 41 pressure on the glued together areas of the folding tabs 39 and inner blanks 14 is exercised. This causes the glue areas to be compressed flat.

Thereafter, again lateral cutting areas 43 of the inner blanks 14 are erected by means of folding trays 44 arranged on both sides along the transport path 32 and then applied to certain areas of the upper side of the inner blanks 14 by means of glue units, preferably hot-melt glue, arranged above the transport path 32.

In the next processing step, the blank regions 43 are in turn folded over by movable folding elements 45 arranged on either side of the transport path 32 and glued to the inner blank 14.

By subsequent pressure rollers 46, the bonds are compressed again.

Thereafter, the inner blanks 14 reach the area of the transfer device 47.

The transfer device 47 has, on the one hand, a blank lifter 48 and, on the other hand, a blank slide 49. With the blanking device 48, the inner blanks 14 are lifted from the outer conveyor belts 33 and then pushed off with the blank slide 49 transversely to the transport path 36.

In the region of the transport path 36, the inner blanks 14 are transported with their longitudinal extent parallel to the transport direction. The transport path 36 is again formed by conveyor belts 50, namely a pair of parallel conveyor belts 50a, 50b, which run parallel to the transport direction. The inner blanks 14 in turn lie flat on an upper side or an upper strand of the conveyor belts 50.

Also, the conveyor belts 50a have holding members in the form of cams 51, with which the inner blanks 14 are detected in this case only on the back. To bridge the distance between the two transport paths 32, 36, a pair of rotationally driven preferred pairs of rollers 52 are arranged, between which the inner blanks 14 are conveyed through until they are detected by the cams 51.

The transport path 36 then transports the inner blanks 14 further to the folding turret 21, where they are pressed in a known manner by a blanking dipper 53 into the pockets of the folding turret 21 before the cigarette blocks 11 are inserted into the partially folded inner blanks 14 after a partial rotation of the folding turret 21 become.

On the way to Faltrevolver 21 two glue stations are provided in the transport path 36 as another special feature.

In a first glue station 53 glue is applied to certain areas of the partially folded inner blank 14. The glue is preferably Holt-Melt glue of the type PSA (pressure-sensitive adhesive). The glue is applied by means of a contact application station 54 on the inner blank 14, wherein the glue station 53 is arranged in this embodiment substantially below the transport path 36. However, an arrangement above the transport path 36 is also conceivable.

The contact application station 54 has a glue nozzle 55 which is adapted to transfer a (thin) layer of glue to a transfer member in the form of a transfer roller 56. In this case, the glue nozzle 55 is arranged stationary and a peripheral surface of the transfer roller 56 abuts the glue nozzle 55, wherein the transfer roller 56 is driven to rotate the glue. The transfer roller 56 is rotationally driven about a horizontal axis and is positioned such that the peripheral surface is in the transport path 36 so that the glue can be transferred from the transfer roller 56 to the underside of the inner blanks 14 conveyed in the transport path 36. This solution is based on the recognition that PSA glue must be applied in the contact process as a thin glue film. Since an immediate order on the individual inner blanks 14 is not possible, the arrangement of the transfer roller 56 has been selected as an intermediate member.

The glue nozzle 55 is driven by a suitable control such that the lateral surface of the transfer roller 56 is provided with short glue marks, which are matched in size and distance to each other on the transport of the inner blanks 14 in the transport path 36.

Another special feature is that the transfer roller 56 between the two conveyor belts 50a, 50b of the transport path 36 is arranged.

Furthermore, at least the peripheral surface of the transfer roller 56 may comprise silicone, such that the glue tracks are transferable to the inner blanks 14. The use of silicone at this point has the advantage that the glue adheres less to the silicone than to the inner blank 14, so that the glue can reliably be removed from the transfer roller 56 and adheres to the inner blanks 14.

The first glue station 53 can also be used in other packaging machines, therefore, this protection is claimed regardless of the specific application.

Downstream of the first glue station 53, a second glue station 57 is arranged above the transport track 36. This serves in the present case for the application of cold glue to certain areas of the inner blanks 14. The glue station 57 has a plurality of juxtaposed glue nozzles 58, with which the glue on the top of the inner blanks 14 is transferable.

Following the gluing of the inner blanks 14 they are pushed by the transport path 36 and the conveyor belts 50 by means of at least one slider 59 in the region of the folding turret 21 and there successively pressed by the blank shank 53 in the pockets of the folding turret 21.

After partial rotation of the folding turret 21, the cigarette blocks 11 are inserted into the ready in the pockets interior blanks 14, by means of the slider 29. During further transport on the folding turret 21, the inner blanks 14 are folded in a conventional manner to the cigarette blocks 11 and ejected to form the Inner packing 12.

Section III - Packing Transport

The interior packs 12 coming from the folding turret 21 (inner blanks 14 with cigarette blocks 11) are essentially finished except for gluing side tabs in the area of narrow sides. This gluing takes place in the further course of the packaging line 16, which is formed by the board web 30. In the cardboard web 30, the partially folded inner blanks 14 are transported with a cover side in the conveying direction and lying flat, with a front side facing up, to be glued and folded folding flaps 62 protrude laterally from the inner blanks 14 in the horizontal direction. On the reverse side, the inner blanks 14 are grasped by carriers 63 arranged on a transport belt 61 and moved along the cardboard web 30 in the conveying direction.

In the area of the board web 30, the glue unit 22 is arranged, which has in each case below the folding tabs 62 glue discs 64 with which glue is transferred to the undersides of the folding tabs 62. Above the folding tabs 62 and the glue discs 64 each roller-shaped counter-holder 65 are provided. Glue discs 64 and counter-holder 65 are arranged at a small distance from each other, so that the folding tabs 62 can be passed between the mutual organs, with the transfer of glue from the glue discs 64 to the folding tabs 62nd

After gluing the folding tabs 62 they are moved by folding means not shown, preferably folding switches, in the plane of the side wall of the inner blanks 14 and connected with corresponding folding tabs of the inner blanks 14 to a narrow side wall.

The interior packings 12 which have been completed so far are transported further along the board web 30 until they reach the area of the second folding turret 24 and are pushed there again by means of a slide 66 into pockets of the folding turret 24.

Section IV - Folding outer cut and drying of the pack

A special feature is the preparation and feeding of the outer panels 15 to the folding turret 24th

The outer blanks 15 are held ready as a stack in a blank magazine 67 and individually removed on the underside from the blank magazine 67 and deposited in a transport path 68.

The transport path 68 runs in this case parallel to the packaging line 16 and at a distance therefrom.

The transport path 68 is adjoined by a further transport path 69, which runs transversely to the transport path 68 and to the packaging line 16 and feeds the outer blanks 15 to the folding turret 24.

In the region of the transport path 68 a plurality of conveyor belts 70, 71 are arranged, which run parallel to each other and directed to the longitudinal direction of the transport path 68.

The outer panels 15 are not in the region of the transport path 68 directly on the conveyor belts 70, 71, but on a transport plate 107 in the recesses 108 for the conveyor belts 70, 71 are provided. The outer panels 15 are spaced apart flat on the top of the transport plate 107 and are directed with their longitudinal extent transverse to the transport direction.

The outer panel 15 are held in the transport path 68 by holding means in the form of cams 72, which rest against the outer panels 15 in the region of side edges thereof and protrude beyond the transport plate 107. Preferably, the outer panels 15 are held in the transport direction and transversely thereto by the cam 72. The cams 72 are formed on the conveyor belts 70, 71. The cams 72 of outer conveyor belts 71a, 71b hold the outer panels 15 only transverse to the longitudinal direction of the transport path 68, whereas the cams 72 of inner conveyor belts 70a, 70b hold the outer panels 15 only in the longitudinal direction of the transport path 68.

The conveyor belts 70, 71 have a different length in the transport direction, wherein outer conveyor belts 71 a, 71 b are shorter than inner conveyor belts 70 a, 70 b and at a distance before a transfer device 73 end, so that the outer panels 15 only through the cams 72 of the inner Transport belts 70a, 70b are held in the longitudinal direction of the transport path 68 and can be deported transversely to the transport path 68 on the transport path 69.

During the cyclical transport of the outer panel 15 along the transport path 68, the outer panels 15 are subjected to successive processing steps. The outer panels 15 pass through, among other things, the following folding stations and glue stations:

First, folding flaps of the outer blank 15 for a cover of the pack 10 are prefolded in a first processing station. For this purpose, a special folding unit 74 is used, which will be described below.

In the next processing station 75 glue is applied to the top of the outer panels 15 by means of several glue units.

In the subsequent processing station two further folding units 76, 77 are provided with which further areas of the outer panel 15 are folded. These two units will be described in detail below.

This is followed by another processing station in which glue is again applied to the upper side of the outer blanks 15 with the aid of glue units 78.

This is followed by the next processing station with two other folding units 79, 80 connects.

Thereafter, the outer blanks 15 reach the area of the transfer device 73. The glue units 75, 78 are used to apply hot-melt glue to the outer blanks 15.

The first folding unit 74 is a device for folding folding flaps for a cover of the pack 10. In this case, a pivotable Formfalter 81 is mounted laterally of the transport path 68, which in conjunction with two switches 82, 83 for a V-shaped folding in Area of the later cover provides ( Fig. 12 ).

In the folding unit 76, the folding of the outer cut 15 in the region of the lid of the pack 10 is continued. For this purpose, the folding unit 76 has three essential components, namely a shaped fork 84, Ecklappenfalter 85, 86 and a punch 87th

The form fork 84 is approximately U-shaped, with two approximately square in cross-section Formgabelarmen 88. The forming fork 84 is shown in arrow 89 in FIG Fig. 13 on the Outer cut 15 pushed so that the Formgabelarme 88 are each positioned on the inside of (cover) corner tabs 90 of the outer panel 15. In the next method step, the corner tabs 90 are grasped and erected by a pair of corner flap folders 85 arranged below the transport path 68 until they abut against the outer flanks of the form fork arms 88. The Ecklappenfalter 85 are pivotally driven for this purpose below the transport path 68 on a common axis 91. Free ends of the Ecklappenfalter 85 are formed cranked for abutment of the corner tabs on the outside of the forming fork arms 88. The so far erected Ecklappen 90 are folded by a pair of above the transport path 68 arranged further Ecklappenfaltern 86 on the Formgabelarme 88. Also, the upper pair of Ecklappenfaltern 86 is pivotable about a common axis 92. In the region of free ends of the Ecklappenfalter 86 transverse folding arms 93 are arranged for detecting the corner tabs 90 above the Formgabelarme 88 and folding the same between the two Formgabelarme 88. The folding is completed by the punch 87, which is movable up and down in the vertical direction. With the punch 87, the corner tabs 90 are folded against the forming fork arms 88 and on the top of the outer panel 15 and connected to the outer panel 15 by the applied in the previous processing station glue. For folding the corner tabs 90 against the contour of the forming fork arms 88, the punch 87 has recesses 98 which are adapted to the contour of the form fork arms 88.

At the same time as the folding of the corner flaps 90, transverse fold tabs 94 of the outer cut 15 are folded, which serve to form a window in the outer pack 13. The Querfaltlappen 94 may be formed by punching and are erected by a pair of arranged below the transport path 68 Fensterlappenfaltern 95. The Fensterlappenfalter 95 are each pivotally mounted on a separate axis 96 and are formed to the free end cranked to fold over the Querfaltlappen 94 by an angle of more than 90 °. After the sash butterflies 95 the Querfaltlappen 94 in the in Fig. 14 shown position above the transport path 68 arranged stamp 97 is used, which is movable in the vertical direction and the Querfaltlappen 94 presses against the top of the outer panels 15. By appropriate glue application in the previous processing station, the folding tabs 94 are thereby connected to the outer panel 15.

The folding unit 79 is an organ for folding the folding flaps of the lid prefolded in the folding unit 74 onto the outer panel 15, namely in the area of the folded corner flaps 90 in the folding unit 76. The folding unit 79 has a U-shaped cross-section which forms the transport path 68 is open. The folding unit 79 can be moved transversely to the transport path 68, taking along the folding tabs of the lid and plant the same at the top of the outer panel 15. In this position, the parts of the outer panel 15 are compressed by a horizontally oriented leg 99 of the folding unit 79. To connect the regions of the outer cut 15, glue has already been applied to the corresponding regions in the preceding processing station.

The folding unit 80 is used for folding longitudinal folding tabs 100 for the window in the outer package 13. The folding unit 80 can be constructed in the same way as the folding unit 77 described above. However, here the corresponding machining elements act in a different, transverse direction than in the folding unit 77.

Following the folding units 79, 80, the outer blanks 15 reach the area of the transfer device 73. The transfer device 73, like the transfer device 47, consists of a blank lifter 48 and of a blank slide 49. The blank blanks 48 are used to cut the outer blanks 15 of FIG lifted off the outer conveyor belts 71 and then deported transversely to the transport path 69 with the blank slide 49.

In the region of the transport path 69, the outer panels 15 are transported with their longitudinal extent parallel to the transport direction. The transport path 69 is formed by a transport belt 101. The outer panels 15 lie flat on an upper side or an upper strand of the transport belt 101. Also, the transport belt 101 has retaining members in the form of cams 102, with which the outer panels 15 are detected in this case only on the back. To bridge the distance between the two transport paths 68, 69, a pair of rotationally driven preferred pairs of rollers 103 are arranged, between which the outer panels 15 are conveyed through until they are detected by the cams 102.

The transport path 69 then transports the outer blanks 15 further to the folding turret 24, where they are pressed into the pockets of the folding turret 24 in a known manner by a blank tap 104 before the inner packages 12 are pushed into the partially folded outer blanks 15 after a partial rotation of the folding turret 24 become.

On the way to Faltrevolver 24 a glue unit 105 is disposed above the transport path 69, is applied with the cold glue on the top of the outer panels 15. The glue serves to connect the outer cut with the inner pack 12 or the inner cut 14 in the folding turret 24.

In the folding turret 24, the outer panels 15 are folded around the inner packages 12 in a known manner. The folding is completed in the region of the transport path 106 adjoining the folding turret 24, in which the glue unit 25 is arranged for gluing side tabs of the outer blanks 15. This and the application of the side flaps of the outer panels 15 can be done in the same manner as in the area of the glue unit 22 for the inner blanks 12th

A special feature still exists with regard to the orientation of the cigarettes or the cigarette block 11 during transport along the packaging line 16. The cigarette blocks 11 are inserted into the first folding turret 21 in such a way that the filter ends of the cigarettes are at the rear in the transport direction. After the first folding turret 21, the filter ends consequently in the transport direction and forward. In this orientation, the cigarettes or the cigarette blocks 11 are also inserted into the second folding turret 24. The peculiarity consists in the fact that the outer panels 12 are arranged pointing in the folding turret 24 with a lid folding tabs for Revolvermitte and a folding tab for the box front wall protrudes from the pockets of the revolver.

Another special feature is that for the connection of outer cut 15 and inner blank 14, the lid of the outer panels 15 are arranged at an angle to the horizontal turret plane in the pockets of the folding turret 24.

The finished packs 10 are inserted into the first drying turret 18 and, after at least one circulation via a jam section 106, fed to a second drying turret 19. In the present case, the buffer path 106 runs transversely to the upstream transport path 106. Following the drying turret 18, the packing 10 can be further processed.
