Abstract

During the production of sealed (cigarette) packs an inner pack (12) is provided with a film envelope (13) surrounding the pack content (group of cigarettes (11)). The group of cigarettes (11) is partially surrounded by an inner collar (14) having a collar front wall (22). The film envelope is cut off from a tubular film (18) of a continuously fed web of film (17). The pack content - block of cigarettes (16) is fed by a block conveyor (27) which interlockingly fixes the blocks of cigarettes (16). In the region of the web of film (17) or the tubular film (18) a connection to the block of cigarettes (16) or to the inner collar (14) is established, namely by thermal joining, gluing or the like, such that the block of cigarettes is fixed in a precise relative postilion to the web of film (17) even once it has left the block conveyor (27).

METHOD AND DEVICE FOR PRODUCING PACKS, ESPECIALLY CIGARETTE PACKS

description

The invention relates to methods for producing (cigarette) packages according to the preamble of claim 1. Furthermore, an apparatus for producing the packages is the subject of the invention. The focus is on cigarette packs with a sealing foil enveloping a group of cigarettes as an inner pack. Within the packing there is a support member for the cigarette group, namely an inner collar (DE 10 2011 119 344 A1). This is tray-like, namely with a collar front wall or -oberwand, transverse side or support walls and a bottom wall or a collar bottom. The inner collar is arranged so that the front or upper wall of the front side of the inner pack, namely facing an inner front wall. In the region of an end face and on the back side, the cigarette group is preferably not covered by the inner collar. The unit of cigarette group and inner collar - hereafter: cigarette block - forms the contents of the inner pack. This can be arranged in an outer pack, preferably in a folding box.

The invention is concerned with the manufacture of the cigarette block and the inner package. In particular, it involves the production of a pack of foldable blank for a cigarette group, preferably in the embodiment as an inner collar of a foil pack.

To solve this problem, the inventive method has the features of claim 1.

A special feature is the preparation of the tray-like inner collar and the merging of the same with the cigarette group to form the

CONFIRMATION COPY Cigarette block. The blank for the inner collar is erected and folded in the area of a folding turret. Afterwards the cigarette group - also in the area of the folding turret - is introduced into the (tray-like) inner collar. Finally, the cigarette block thus produced is transferred to a discharge conveyor - block conveyor - with the inner collars being positioned with the collar front wall facing upwards. In this relative position, the units arrive at a wrapping station for attaching the sealing film to form the inner package. A further special feature are measures for folding folding flaps in the area of a collar bottom to produce a glue-free connection of the folding flaps, exclusively by plug connection.

Device (XIV in Fig. 3),

15 a pack - inner pack - as a finished product in perspective,

Fig. 16 shows a detail XVI of Fig. 15 in an enlarged scale. It is about the manufacture of packs for cigarettes 10 or a cigarette group 11 or other smokers. The immediately produced pack, namely inner pack 12 (FIG. 15), consists of the cigarette group 11 and a wrapping made of sealing film, namely a film wrapping 13, which surrounds it completely. Inside the inner pack 12, a protective or supporting organ is preferably arranged from (thin) cardboard , namely an inner collar 14.

For the production of an inner packing 12 with cigarette group 11, film wrapping 13 and inner collar 14, the inner collar 14 is manufactured in a first step and filled with a cigarette group 11. The unit thus formed - cigarette block 16 - is fed to a wrapping station 15, in which the transverse and with a predetermined distance transported cigarette blocks 16 reach the region of a continuous film web 17 and are enveloped by this. In a conveying section of the film web 17, this is shaped as a film tube 18, in the present example (FIG. 14) with a continuous tubular seam formed on the underside. The cigarette blocks 16 are disposed within the film tube 18 at a distance from each other. In a sealing and separating station 19 transversely directed sealing seams 20, 21 in the embodiment as a fin seam are produced in the middle between successive cigarette blocks with simultaneous cutting of the film tube 18 between the successive cigarette blocks 16 in the region of the sealing seams 20, 21, so that inner packs 12 with lateral, protruding sealing seams 20, 21 in the area of side walls - inside walls - arise, in the execution as a fin seam.

The inner collar 14 can be formed in various ways, but has at least one large front wall or collar front wall 22 and on both sides transverse side tabs, so that the inner collar is formed in cross-section U-shaped. In the present, particular embodiment, a transverse to the walls 22, 23, 24 end wall is further provided, namely a collar bottom 25. Overall, therefore, the inner collar 14 is tray-shaped. Collar edges formed between collar front wall 22 and side flaps 23, 24 are designed as beveled edges 26 with two parallel fold lines (FIG. 7).

The cigarette blocks 16 formed in this way or in a similar manner are transported by a block conveyor 27 into the wrapping station 15. The block conveyor 27 transports the cigarette blocks 16 at exact distances from each other, in the present case by at least one rear driver 28 and preferably a front stop 29.

The prepared film web 17 is lowered in the region of the wrapping station 15 from above onto the block conveyor 27 or the successive cigarette blocks 16 and placed on the collar front wall 22. Laterally projecting areas are formed around the cigarette blocks 16 by stationary guiding and folding organs. The block conveyor 27 ends in the region of the wrapping station 15 by deflecting at a guide roller 30 down. In this area, the film web 17 is folded so far that the film tube 18 is formed, the cigarette blocks 16 while maintaining the relative position entraining. At about the same time, the tubular seam (not shown in FIG. 14) is produced, which stabilizes the envelope of the cigarette blocks 16.

In order to secure the relative position of the cigarette blocks 16 on the film web 17 or in the region of the film tube 18, the film web 17 is fixed to the cigarette blocks 16, in particular on the upwardly directed collar front wall 22. The connection can be made by means of glue fields. In the present case, however, a connection is produced by thermal sealing. The film web 17 is subjected to heat and pressed against the collar front wall 22, whereby a sufficient connection is formed. In the exemplary embodiment according to FIG. 14, an elongate sealing member is arranged above the film web 17 or the film tube 18, which transfers heat and pressure to the film web 17 over a sufficient transport distance. It is a tracking belt 31 and a stationary sealing jaw 32, which rests against the free side of a running (lower) run of the belt 31. The run of the belt 31 runs frictionless with the film web 17 and transfers heat and pressure in the region of the collar front wall 22. It is important that the sealing unit 31, 32 extends into the region of the block conveyor 27, so that the fixation already takes place while the packages or the cigarette blocks 16 are positively guided by the block conveyor 27. Thereafter, the connection between the film web 17 and cigarette blocks 16 is sufficient to obtain the relative position.

A (further) special feature is the production of the cigarette blocks 16, that is, the combination of cigarette groups 11 with inner collar 14.

The first manufacturing step is concerned with the inner collar 14. A blank for the inner collar 14, corresponding to the embodiment in FIG. 1, is produced by separating from a material web 33 (of thin cardboard) in the area of a knife block 34. This is the case formed so that the blank 14 separated from the web 33 and then by two pairs of knife rollers 35, 36 two groups of punching lines and perforations are attached to limit the side tabs 23, 24 and the complex folding flaps of the collar bottom 25. The individual Blanks for Inner collar 14 are then carried along by conveyor belts 37 and transferred to a special feed conveyor 38, which successively feeds the blanks 14 to a folding turret 39 rotating in a vertical plane (cyclically). The feed conveyor 38 consists of a continuous base for the blanks 14 - track plate 40 - on which the blanks 14 are transported at a distance from each other by upper straps 41, by detecting means of drivers to handover to the folding turret 39. The folding turret 39 has a A plurality of pockets 42, each for receiving a blank 14. The pockets 42 are attached to radially directed straps and open to the outside. In the present case, the folding turret 39 rotating about a horizontal axis is formed with eight uniformly distributed pockets 42. The blanks 14 are transferred in the region of a transfer station 43 to the folding turret 39, namely introduced into a respective upwardly directed pocket 42. The transfer takes place in such a way that the blank (unfolded) blank 14 is held above the pocket 42 (FIG. 7) which is essentially U-shaped in cross-section, moved downwards by a lowering member, in this case by a punch 44, and into the pocket 42 is introduced. In this case, arranged on the blank 14 folding tabs 23, 24, 25 erected. The punch 44 is moved downwards from an upper starting position (FIG. 3) into a lower end position (FIGS. 6, 7) in the pocket 42. The inner collar 14 then rests in the pocket 42 with the collar front wall 22 a pocket bottom 45 with upright side tabs 23, 24. The punch 44 is provided with a (lower) punch plate 46, which corresponds in the dimensions and contours of the pocket 42.

In connection with the insertion of the blank 14 in the (upwardly facing) pocket 42 takes place a plurality of sometimes complex folding steps. Accordingly, the transfer station 43 is equipped with different organs. The blanks 14 are transported by the feed conveyor 38 to an exact position above the bag 42 to be charged, until it abuts a stop 47. This is present bow-shaped (Fig. 5), wherein the blank 14 against a lower crossbar is driven.

The - 14 transverse to the longitudinal extent - blank 14 is adjusted in the transfer position (initially) by organs in the transverse direction and held. In the present case, alignment levers 48, 49 are arranged on both sides of the path of movement of the blanks 14 above the pocket 42. The alignment lever 48, 49 are pivotally mounted and actuated by means of articulated levers 50 via tie rods 51, such that the alignment lever 48, 49 can be pivoted about a pivot bearing 52. In the alignment and support position shown in FIG. 5, a blank 14 is held on opposite sides - in the region of the folding tabs for the collar bottom 25 on the one hand and opposite in the region of frontal ends on the other - by an alignment lever 48, 49 in exact relative position. The alignment levers 48, 49 have horizontally directed receptacles for end regions of the blank 14, in the present case longitudinally extending retaining slots 53, 54. These are dimensioned such that on the one hand they carry the blank 14 and on the other hand cause an adjustment thereof transversely to the conveying direction. The blank 14 is in each case conveyed by the feed conveyor 38 into this position (FIG. 5). When the blank 14 is moved downwardly into the pocket 42 by the punch 44, the alignment levers 48, 49 are guided by pivoting movement into a release position (FIG. 6), in which the blank 14 is wholly or partly made up of the holding slots 53, 54 exit and exposed for the downward movement.

In the downward movement into the pocket of the blank 14 by a Faltbzw. Raising member moved through, such that the folding tabs 23, 24, 25 in an (approximately) upright position - transverse to the collar front wall 22 - are folded or prefolded. The Aufrichtorgan is designed so that it has in the range of movement of the folding tabs 23, 24 of the blank 14 folding webs 55 parallel to these folding flaps and rounded folding edges 56. As a whole, the folding member 57 is fork-shaped or U-shaped with the two parallel lateral folding webs 55 only for the folding tabs 23, 24 (with corner tabs 67) and the crossbar 58 as a connecting means for the folding webs 55th

The folding member 57 is adjusted in the introduction of a blank 14 in the pocket 42. In an (upper) starting position (Fig. 5), the folding member 57 is at a greater distance above the pocket 42, but below the plane of the prepared blank 14. When it is moved with the punch 44 down or towards the pocket 42 , the folding member 57 follows this (downward) movement. In the lower position, the folding member 57 is located immediately above the pocket 42, so that when folding the blank 14 into the pocket, the folding tabs are erected.

The folding member 57 is connected to an actuating gear - in the region of the transverse web 58 - which in the present case consists of an upwardly and downwardly movable, angular support lever 59 and parallel levers 60 for (linear) up and down movement of the support lever 59 with folding member 57. For the folding of the folding tabs of the collar bottom 25 separate folding members in the region of the transfer station 43 are provided. These are stationary folding means, namely a fixed folding switch 61 next to the pocket 42 or next to the folding turret 39. The folding switch 61 is located below a provision plane for the blank 14 (FIG. 5). However, folding surfaces or folding means are formed above the pocket 42, in the present case an arcuate fold surface 62, which elevates a leg of folding tabs for the collar bottom 25 during the downward movement. In the end position of the blank 14 in the pocket 42, accordingly, on the one hand, the lateral folding tabs, namely side tabs 23, 24 are erected and, on the other hand, the unit of the folding tabs for the collar bottom 25.

In the pocket 42, the blanks are fixed by additional holding means, in this case by suction.

In the area of upright side surfaces and in the region of the pocket bottom 45, suction bores 63 are arranged distributed in the axial direction of the folding turret 39, so that the collar front wall 22 and the side tabs 23, 24 in the pocket 42 - After insertion - be held by suction. The suction bores 63 are connected to a common suction line 82, which is connected to a central vacuum source. After insertion of the blank 14 in the pocket 42 (Fig. 7), the punch 44 returns by upward movement ung to the starting position (Fig. 5) back. The folding turret 39 is now further rotated by one division section, as a result of which the pocket 42 with blank 14 reaches the region of a folding station 64. In this station 64 of the inner collar 14 is completed, in this case by folding steps in the region of the collar bottom 25. This is complex, namely with a bottom wall 65, a tab 66 and the corner tabs 67. Already in the introduction of the blank 14 in the pocket 42 (in the transfer station 43), the corner tabs 67 are erected or pre-folded by stationary corner folders 83 due to the (downward) relative movement (FIG. 8). The corner tabs 67 are initially in an inclined position - relative to the adjacent side tabs 23, 24. In the further insertion movement of the blank 14, the corner tabs 67 are folded due to the relative position against the inside of the bottom wall 65. During the rotation of the folding turret 39 folding members are effective, the plug tab 66 as part of the collar bottom 25 from the erected position - in the pocket 42 - in a horizontal, ie transverse intermediate position (Fig. 9) move. It is the continued, correspondingly designed folding switch 61, which runs due to appropriate design on the top of the bag 42 and due to the relative movement causes the folding of the insertion flap 66. Accordingly, in an intermediate position, the insertion tab 66 is located as a horizontal leg above the pocket contour (FIG. 9). In the region of the folding station 64, a movable folding member is used, namely a flap folder 68. This is stationary, movably outside the range of movement of the pocket 42 (in the starting position). By downward or oblique movement into the pocket 42 is due to corresponding relative position the - transverse - tab 66 through the Laschenfalter 68 or detected by a Faltnase 69 and moved by the continued movement in obliquely directed plane of movement until it rests against the bottom wall 65 with insertion of an end piece in a plug-in slot adjacent to the bottom wall 65 (Fig. 10). The flap folder 68 then returns to the home position out of the region of the pocket 42. The movements of the tab flap 68 are accomplished by an actuating gear 70, which is shown schematically in FIG.

The bag 42 is now fed to the finished inner collar 14 of a further processing station, namely a filling station 71. This is in terms of alignment by 90 ° offset to the transfer station 43, so directed horizontally with respect to the open side of the bag 42. The bag 42 is closed during movement from the folding station 64 to the filling station 71 on the outside. Each pocket 42 are associated with closing walls 72, 73, which are each arranged on both sides of a pocket 42 on pivot levers 74. The relative position is such that in the open position, the closure walls 72, 73 are positioned completely outside the area of the pocket 42 (Figure 7). When the bag is transferred to the filling station 71, the closing walls 72, 73 move into the closed position, in which they close the free side of the pocket 42 in half (FIG. 4).

In the filling station 71, an otherwise prepared cigarette group 1 1 is kept ready, which is transported by means of group pockets 75 of a cigarette conveyor 76 to the filling station 71 (FIG. 4). The group pockets 75 and the pockets 42 with the inner collar 14 are transported in staggered, parallel planes (FIG. 11). During a standstill phase of both conveyors - folding turret 39, cigarette conveyor 76 - a cigarette group 11 is pushed out of the group pocket 75 by a Ausschuborgan - ram 77 - and introduced into the exactly aligned thereon pocket 42 of the folding turret 39. The relative position is chosen so that the cigarette group 11 passes over the open side of the inner collar 14 - opposite to the collar bottom 25 - in the inner collar 14. The cigarette group 11 is due to corresponding relative position of the pockets 42, 75 in an upright orientation, ie with upright rows of cigarettes. At the radially outer Side of the bag 42, the cigarettes are maintained while maintaining the formation by the closing walls 72, 73.

The units of inner collar 14 and cigarette group 11 - cigarette block 16 - are transferred to the block conveyor 27 in the region of a discharge station 84 (FIG. 12). When handing over the cigarette block 16 to the block conveyor 27, the respective pocket 42 of the folding turret 39 is in a downwardly directed position - opposite to the transfer station 43. The transport path from the filling station 71 to the discharge station 84 is therefore two switching steps of the folding turret 39.

The block conveyor 27 schematically shown here is arranged in a plane offset from the folding turret 39, such that the parcel blocks 16 pushed out of the pocket 42 in the direction parallel to the folding turret 39 are deposited directly on the block conveyor 27, ie between the driver 28 and the stop 29 Discharge is carried out by a slide 78, which passes axially parallel from the free side through the (closed) pocket 42 with entrainment of the cigarette block 16 (FIG. 13). Due to the relative position of the conveyors, it is ensured that the cigarette blocks 16 are deposited on the block conveyor 27 with the collar front wall 22 directed upwards or to the free side, ie corresponding to the further processing (FIG. 14).

During the ejection movement of the cigarette block 16 out of the pocket 42, a holding or supporting member in the region of the collar bottom 25 on the outside becomes effective, namely a reciprocable pick-up 100, which rests with the free end on the collar bottom 25 and is moved synchronously with the ejection movement of the cigarette block 16, so that the cohesion of cigarette group 11 and inner collar 14 is ensured.

The block conveyor 27 is designed so that the holding members for a cigarette block 16, so driver 28 and stop 29, for the acquisition of a cigarette block 16 are movable. According to example in Fig. 12, Fig. 13, a block pocket 79 is mounted on the block conveyor 27, which consists of a through bottom 80 and a fixed side part - driver 28 - consists. Opposite, here at the forward in the conveying direction side, a movable holding member is provided, namely the stop 29, which is attached to a pivot lever 81. This is mounted on the block conveyor 27 designed in a special way, that in the region of a deflection of the same for receiving a cigarette block 16 from the folding turret 39 by corresponding movement of the pivot lever 81 of the stop 29 is moved into an open or in an expanded position (FIG ), so that the insertion of the cigarette block 16 due to increased distance of the lateral boundaries 28, 29 can proceed smoothly.

In the present case, the inner pack 12 is designed in a special way (FIGS. 15, 16). It is a gasket due to the use of a suitable, heat-sealable film. The film envelope 13 is provided with lateral sealing or sealing seams, namely the sealing seams 20, 21. The generally closed inner package 12 is vented in the further process. Excess air is removed from the interior of the package 12, in particular by applying (flat) pressure on the package 12. The film envelope 13 is provided with vents 85, in the region of a rear wall 86 of the film envelope 13, laterally outside the range of the cigarette block 16 (Figure 15). The vents 85 - at least one on each side of the cigarette block 16 - are formed as a U-shaped punched with outward or to the side directed tongue. The vents 85 are closed after removal of the air by another seal in this area.

In addition to the vents 85 - or alternatively to these - air openings 87 are formed in the region of the sealing seams 20, 21, by interrupting the sealing seams 20, 21, so that they form a gap (Fig. 16), in their area the layers or fins of the film envelope 13 are not connected to each other. Here too (additionally) air can escape.

The formed with interruptions sealing seams 20, 21 are formed by appropriately trained, radially directed sealing webs 88 on sealing rollers 89th the sealing and separating station 19 created. The sealing webs 88, which produce double-wide sealing seams and at the same time perform a separating cut, have - here eccentrically - a recess 90 in the outer sealing surface, which leads to the interruption of the sealing seams 20, 21 and thus to the creation of the air opening 87.

Another peculiarity in the area of the sealing and separating station 19 relates to the exact, essentially parallelepipedal design of the (inner) packing 12. It concerns folds in the lateral area of an end wall 93 on the one hand and a bottom wall 94 on the other hand. In the manufacture of the transverse sealing seams 20, 21 through the sealing webs 88 in the sealing and separating station 19, film pieces or gussets directed towards the outside are formed on both sides. In the present case, these are avoided by folding the corresponding lateral regions-in each case adjacent to end wall 93 or bottom wall 94 -inwardly during the production of the (double) sealing seams 20, 21 and during the separating cut between them. The structure resulting from folding and sealing is shown in FIG. 15, FIG. 16.

For this purpose, in the area of the sealing and separating station 19, a fork-shaped folding member 91 is positioned laterally next to the movement path of the inner packings 12 (FIG. 14). The folding member 91 has two folding ends 92 formed by tapering of the profile. These come into the region of an end wall 93 and a bottom wall 94 of the inner pack 12 in a folded position in which Faltzwickel during the formation of the sealing seams 20, 21 are folded inwards, so that the folded position shown in FIG. 15, Fig. 16 is created. The folding members 91 are supported so as to move in the plane of movement of the inner packs 12 during one section and then return to the home position in a retracted position, corresponding to the dot-dashed trajectory in FIG. 14. The configuration and dimensions of the folding members 91 are selected such that the folds 93 formed at the ends of legs during a folding cycle simultaneously process the edge regions of two successive packs 12 by transverse folding movement, ie edge regions of the packs 12 on both sides of the respective effective seal web 88 (FIG. 14). Another technical feature that is implemented in the manufacture of the inner package 12, the attachment of stamping lines 95, 96 for supporting or improving folding edges 97 which limit an inner end wall of the pack 10 in the transverse direction of the inner package 12. The stamping lines 95, 96 result in folding the film wrapping 13 sharp-edged or rectangular folding edges to limit the inner end wall 93. The stamping lines 95, 96 are attached to the continuous film web 17 corresponding to the position of the produced inner end wall 93 while continuous Above the same - in the region of a counter-roller 98 - an embossing roll 99 is mounted, which rests with running around embossing projections and corresponding pressure on the film web and thus by stamping the stamping lines 95, 96 produces.

The relative position of the cigarette blocks 16 in the region of the film web 17 or the film tube 18 stabilizing connection between film and cigarette block or inner collar 14 is effected in that the film (inside) has a suitable for thermal bonding coating, namely in particular sealing wax. By applying heat and pressure, this sealing wax is prastifiziert locally and provides a sufficient for securing the relative position connection to the preferably made of cardboard inner collar 14 ago. Alternatively, the inner collar may be coated with a thermally plasticizable coating and / or with thermally activatable glue and / or with permanent adhesive (locally). When using (cold) glue, only pressure is used in the production of the compound.

In the illustrated embodiment of the method and apparatus (FIG. 14), the film web 17 is supplied at the top of the packs or cigarette blocks 16 and the tube seam for the film tube 18 is formed on the underside. Alternatively, the film web 17 can be fed to the lower side of the device and the film tube can be formed on the upper side. The co-acting aggregates, in particular the pressing or sealing unit 31, 32, is in this alternative according to the underside of Movement path of the cigarette blocks 16 is arranged. These are reversed in their relative position, so that the inner collar 14 is directed downward.
