Abstract

In the production of (cigarette) sealing packs, an inner pack (12) is provided with a foil wrapping (13) surrounding the pack contents (cigarette group (11)). The cigarette group (11) is partially surrounded by an inner collar (14) with a collar front wall (22). The film envelope is separated from a film tube (18) of a continuously fed film web (17). The package contents - cigarette block (16) - is fed by a block conveyor (27) which fixes the cigarette blocks (16) in a form-fitting manner. In the area of the film web (17) or the film tube (18), a connection with the cigarette block (16) or the inner collar (14) is established by thermal bonding, gluing or the like, so that the cigarette block also after leaving the block conveyor (27) is fixed in an exact position relative to the film web (17).

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 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 is about an exact positioning of film wrapping on the one hand and content of the inner pack on the other hand, namely the cigarette block. Furthermore, the production of the inner collar is covered by this innovation.

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

For the exact formation of an inner package, the exact positioning of the cigarette block during the production of the film wrapping is important. A continuous sheet of film is fed to the successively transported cigarette blocks, applied thereto and formed around them to form a film tube. This is completed by attaching a longitudinal sealing seam - tube seam. The fixation of the cigarette blocks on the film web leads to a precise alignment of the cigarette blocks with respect to the film web. The compound can be effected by thermal sealing, alternatively or additionally by glue.

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

It is about the production of packing for cigarettes 10 or a cigarette group 11 or other smoker articles. The immediate pack to be produced, namely inner pack 12 ( 15 ) consists of the cigarette group 11 and a completely surrounding envelope of sealing film, namely a film wrapping 13 , Inside the inner pack 12 a protective or supporting organ of preferably (thin) cardboard is arranged, namely an inner collar 14 ,

For the production of an inner pack 12 with cigarette group 11 , Foil cladding 13 and inner collar 14 becomes in a first step the inner collar 14 made and with a cigarette group 11 filled. The unit thus formed - cigarette block 16 - becomes a serving station 15 supplied in the transverse and with a predetermined distance from each transported cigarette blocks 16 in the range of a continuous film web 17 arrive and be enveloped by this. In a conveying section of the film web 17 this is as a film tube 18 shaped, in the present example ( 14 ) with formed on the underside, continuous tube seam.

The cigarette blocks 16 are inside the film tube 18 spaced apart. In a sealing and separating station 19 Become centered between successive cigarette blocks 16 transverse seal seams 20 . 21 made in the execution as a fin seam with simultaneous cutting through the film tube 18 between the successive blocks of cigarettes 16 in the area of sealed seams 20 . 21 so that interior 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, one is still to the walls 22 . 23 . 24 transversely directed end wall provided, namely a collar bottom 25 , Overall, therefore, the inner collar 14 tray-shaped. Between collar front wall 22 and side lobes 23 . 24 formed collar edges are as beveled edges 26 formed with two parallel fold lines ( 7 ).

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

The prepared film web 17 is in the area of the serving station 15 from the top of the block conveyor 27 or the successive cigarette blocks 16 lowered and on the collar front wall 22 hung up. Laterally protruding areas are around the cigarette blocks 16 formed around by fixed guiding and folding organs. The block conveyor 27 ends in the area of the serving station 15 by deflecting at a deflection roller 30 downward. In this area is the film web 17 folded so far that the film tube 18 arises, the cigarette blocks 16 while maintaining the relative position entrains. Around the same time, the (in 14 not shown), which is the envelope of the cigarette blocks 16 stabilized.

To the relative position of the cigarette blocks 16 at the film web 17 or in the region of the film tube 18 to secure, is the film web 17 at the cigarette blocks 16 fixed, 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 foil web 17 is subjected to heat and to the collar front wall 22 pressed, creating a sufficient connection. In the embodiment according to 14 is above the film web 17 or of the film tube 18 arranged an elongated sealing member, which over a sufficient transport distance heat and pressure on the film web 17 transfers. It is a tracking belt 31 and a stationary sealing jaw 32 on the free side of a running (lower) run of the belt 31 is applied. The strand of the belt 31 runs smoothly with the film web 17 and transmits heat and pressure in the area of the collar front wall 22 , It is important that the sealing unit 31 . 32 into the area of the block conveyor 27 extends, so that the fixation already takes place while the packs or the cigarette blocks 16 through the block conveyor 27 are forced. After that is the connection between the film web 17 and cigarette blocks 16 sufficient to obtain the relative position.

Another (special) feature is the production of the cigarette blocks 16 So the merger of cigarette groups 11 with inner collar 14 ,

The first manufacturing step deals with the inner collar 14 , A blank for the inner collar 14 , according to the execution in 1 , is made by cutting off a material web 33 (made of thin cardboard), in the area of a knife block 34 , This is designed so that the cut 14 from the material web 33 separated and then by two pairs of knife rollers 35 . 36 two groups of punched lines and perforations are attached, to limit the lateral lobes 23 . 24 as well as the complex folding flap of the collar bottom 25 , The individual cuts for inner collar 14 are then by conveyor belts 37 taken along and a special feeder 38 hand over the blanks 14 successively in a vertical plane (intermittently) rotating folding turret 39 supplies.

The feeder 38 consists of a continuous base for the blanks 14 - Railway plate 40 - on which the blanks 14 spaced apart by upper straps 41 be transported, by detecting by means of drivers until the handover to the folding turret 39 ,

The folding turret 39 has a plurality of pockets 42 on, each for receiving a blank 14 , The bags 42 are attached to radially directed beams and open to the outside. In the present case is the folding turret rotating about a horizontal axis 39 with eight evenly spaced pockets 42 educated.

The blanks 14 are in the area of a transfer station 43 to the folding turret 39 passed, namely in a respective upward pocket 42 introduced. The transfer takes place in such a way that the (unfolded) blank 14 above the pocket, which is essentially U-shaped in cross-section 42 ( 7 ) held by a Absenkorgan, in this case by a stamp 44 , moved down and into the bag 42 is introduced. It will be on the blank 14 arranged folding flaps 23 . 24 . 25 erected. The Stamp 44 becomes from an upper starting position ( 3 ) moved down to a lower end position ( 6 . 7 ) in the bag 42 , The inner collar 14 then lies in the bag 42 with the collar front wall 22 on a pocket bottom 45 with erect side lobes 23 . 24 , The Stamp 44 is with a (lower) stamp plate 46 provided in the dimensions and contours of the bag 42 equivalent.

In connection with the insertion of the blank 14 in the (upwards) bag 42 takes place a plurality of sometimes complex folding steps. Accordingly, the transfer station 43 equipped with different organs.

The blanks 14 be through the feeder 38 to an exact position above the bag to be loaded 42 transported, until it touches a stop 47 , This is in this case bow-shaped ( 5 ), with the blank 14 is driven against a lower crosspiece.

The - with the longitudinal extent transverse - cut 14 is adjusted in the transfer position (initially) by organs in the transverse direction and held. Here are above the bag 42 Unilever 48 . 49 on both sides of the path of movement of the blanks 14 arranged. The alignment lever 48 . 49 are pivotally mounted and by means of articulated levers 50 over tie rods 51 operable, such that the alignment lever 48 . 49 around a pivot bearing 52 can be swiveled. In the alignment and support position according to 5 becomes a blank 14 on opposite sides - in the area of the folding flaps for the collar floor 25 on the one hand and opposite in the area of the front ends on the other hand - by a respective alignment lever 48 . 49 held in exact relative position. The alignment lever 48 . 49 have horizontally directed receptacles for end sections of the blank 14 , in the present case longitudinally extending retaining slots 53 . 54 , These are sized so that on the one hand the cut 14 on the other hand carry an adjustment of the same transversely to the conveying direction. The cut 14 is in each case by the feed conveyor 38 into this position ( 5 ). When the cut 14 - by the stamp 44 - moves downwards into the bag 42 , become the alignment lever 48 . 49 by pivoting movement into a release position ( 6 ), in which the blank 14 wholly or partially from the retaining slots 53 . 54 exit and exposed for the downward movement.

During the downward movement into the bag, the blank becomes 14 moved through a folding or Aufrichtorgan, such that the folding flaps 23 . 24 . 25 in an (approximately) upright position - transverse to the collar front wall 22 Folded or prefolded. The Aufrichtorgan is designed so that it is 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 having. In the whole is the folding organ 57 fork-shaped or U-shaped with the two parallel lateral folding webs 55 only for the folding flaps 23 . 24 (with corner lobes 67 ) and the crossbar 58 as a connecting means for the folding bars 55 ,

The folding organ 57 is when introducing a blank 14 in the pocket 42 adjusted. In an (upper) starting position ( 5 ) is the folding organ 57 at a greater distance above the bag 42 but below the level of the blank provided 14 , If this with the stamp 44 down or towards the bag 42 is moved, follows the folding organ 57 this (downward) movement. In the lower position is the folding organ 57 just above the bag 42 , so when introducing the blank 14 in the pocket the folding flaps are erected.

The folding organ 57 is connected to an actuating gear - in the area of the crosspiece 58 -, Which in this case from an up and down movable, angular support lever 59 and parallel levers 60 for (linear) up and down movement of the support lever 59 with folding organ 57 consists. For folding the folding flaps of the collar bottom 25 are separate folding organs in the area of the transfer station 43 intended. These are stationary folding means, namely a fixed folding switch 61 next to the bag 42 or next to the folding turret 39 , The folding switch 61 is below a cut-ready deployment level 14 ( 5 ). However, folding surfaces or folding means are above the bag 42 formed, in this case an arcuate fold surface 62 , which in the downward movement, a leg of folding flaps for the collar-bottom 25 erects. In the final position of the blank 14 in the bag 42 are therefore on the one hand the lateral folding lobes, namely side lobes 23 . 24 erected and on the other hand, the unit of folding flaps for the collar floor 25 ,

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

In the area of upright side surfaces and in the area of the pocket bottom 45 are suction holes 63 in the axial direction of the folding turret 39 arranged distributed so that the collar front wall 22 and the side lobes 23 . 24 in the bag 42 - After insertion - be held by suction. The suction holes 63 are connected to a common suction line 82 connected, which is connected to a central vacuum source.

After insertion of the blank 14 in the pocket 42 ( 7 ) the stamp returns 44 by upward movement into the starting position ( 5 ) back. The folding turret 39 is now further rotated by a division section, causing the bag 42 with cut 14 in the area of a folding station 64 arrives. In this station 64 becomes the inner collar 14 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 pin 66 and the corner lobes 67 , Already at the introduction of the blank 14 in the pocket 42 (in the transfer station 43 ) become the corner lobes 67 through fixed corner butterflies 83 due to the (downward) relative movement erected or prefolded ( 8th ). The corner lobes 67 are initially in an inclined position - relative to the adjacent side lobes 23 . 24 , In the further introduction movement of the blank 14 become the corner lobes 67 due to the relative position against the inside of the bottom wall 65 folded.

During the rotation of the folding turret 39 Folding organs are effective, the plug-in flap 66 as part of the collar bottom 25 from the upright position - in the bag 42 - in a horizontal, ie transverse intermediate position ( 9 ) move. It is the continued, appropriately trained Faltweiche 61 , due to appropriate design at the top of the bag 42 runs and due to the relative movement, the refolding of the insertion flap 66 causes. In an intermediate position is therefore the insertion flap 66 as a horizontal leg above the pocket contour ( 9 ).

In the area of the folding station 64 a movable folding organ is used, namely a flap folder 68 , This is stationary, movable outside the range of movement of the bag 42 (in the starting position) arranged. By downward or oblique movement in the bag 42 is due to corresponding relative position the - transverse - insertion tab 66 through the flap butterfly 68 or by a Faltnase 69 detected and by the continued movement in an inclined plane of movement until it touches the bottom wall 65 moved with the introduction of an end piece in a slot next to the bottom wall 65 ( 10 ). The flap butterfly 68 then returns to the starting position outside the area of the bag 42 back. The movements of the flap-butterfly 68 be through an actuating gear 70 accomplished, which schematically in 4 is shown.

The pocket 42 Now with the finished inner collar 14 fed to a further processing station, namely a filling station 71 , This is in terms of alignment by 90 ° offset to the transfer station 43 that is the open side of the bag 42 directed horizontally. The pocket 42 gets in motion from the folding station 64 to the filling station 71 closed on the outside. Every bag 42 are closing walls 72 . 73 assigned to each side of a bag 42 on swivel levers 74 are arranged. The relative position is such that in the open position, the closing walls 72 . 73 completely outside the area of the bag 42 are positioned ( 7 ). When transferring the bag to the filling station 71 arrive the closing walls 72 . 73 in the closed position, in which they are the free side of the bag 42 - half each - close ( 4 ).

In the filling station 71 becomes an otherwise prepared cigarette group 11 kept ready by means of group bags 75 a cigarette conveyor 76 to the filling station 71 is transported ( 4 ). The group bags 75 and the bags 42 with the inner collar 14 are transported in staggered, parallel planes ( 11 ). During a stoppage phase of both conveyors - folding turret 39 , Cigarette conveyor 76 - becomes a cigarette group 11 by a Ausschuborgan - plunger 77 - from the group bag 75 pushed out and into the exactly aligned pocket 42 the folding turret 39 introduced. The relative position is chosen so that the cigarette group 11 over the open side of the inner collar 14 - opposite to the collar floor 25 - in the inner collar 14 arrives. 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. On the radially outer side of the bag 42 The cigarettes are maintained while maintaining the formation through the closing walls 72 . 73 held.

The units of inner collar 14 and cigarette group 11 - cigarette block 16 - be in the area of a discharge station 84 ( 12 ) to the block conveyor 27 to hand over. At the handover of the cigarette block 16 to the block conveyor 27 is the respective bag 42 the folding turret 39 in a downward position - opposite to the transfer station 43 , The transport route from the filling station 71 to the discharge station 84 is therefore two switching steps of the folding turret 39 ,

The block conveyor shown schematically here 27 is offset in one plane to the folding turret 39 arranged, such that the axis in the direction parallel to the folding turret 39 out of the bag 42 pushed out cigarette blocks 16 directly on the block conveyor 27 be stored, ie between drivers 28 and stop 29 , The ejection is done by a slider 78 , the paraxial from the free side through the (closed) bag 42 passes along with the cigarette block 16 ( 13 ). Due to the relative position of the conveyor it is ensured that the cigarette blocks 16 with collar front wall directed upwards or to the free side 22 on the block conveyor 27 be filed, so according to the further processing ( 14 ).

During the ejection movement of the cigarette block 16 out of the bag 42 becomes a holding or supporting member in the region of the collar bottom 25 effective on the outside, namely a reciprocating pickup 100 , with the free end on the collar floor 25 abuts and synchronously with the Ausschubbewegung the cigarette block 16 is moved, so the cohesion of cigarette group 11 and inner collar 14 is guaranteed.

The block conveyor 27 is designed so that the holding members for a cigarette block 16 So takeaway 28 and stop 29 , for taking over a cigarette block 16 are movable. According to example in 12 . 13 is at the block conveyor 27 a block bag 79 attached, consisting of a continuous floor 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 that is on a pivoting lever 81 is appropriate. This is so on the trained in a special way block conveyor 27 stored, that in the region of a deflection of the same to take over a cigarette block 16 from the folding turret 39 by appropriate movement of the pivot lever 81 the stop 29 is moved into an open or in an expanded position ( 12 ), leaving the slot of the cigarette block 16 due to increased distance of the lateral boundaries 28 . 29 trouble-free.

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

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

The intermittent sealed seams 20 . 21 be through accordingly formed, radially directed sealing webs 88 on sealing rolls 89 the sealing and separating station 19 created. The seal 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 is used to interrupt the sealing seams 20 . 21 and thus to the creation of the air opening 87 leads.

Another special feature in the area of the sealing and separating station 19 relates to the exact, essentially cuboidal design of the (inner) packing 12 , It is about folding in the lateral area of an end wall 93 on the one hand and a bottom wall 94 on the other hand. In the production of transverse sealing seams 20 . 21 through the seal webs 88 in the sealing and separating station 19 arise on both sides in each case outwardly directed pieces of film or gusset. These are avoided by the fact that the corresponding lateral areas - in each case next to the end wall 93 or bottom wall 94 - are folded inwards, during the production of the (double) sealing seams 20 . 21 and during the separation cut between them. The resulting structure after folding and sealing shows 15 . 16 ,

For this purpose, in the area of the sealing and separating station 19 a fork-shaped folding organ 91 laterally next to the path of movement of the inner packs 12 positioned ( 14 ). The folding organ 91 has two fold ends formed by tapering the profile 92 on. These occur in the area of an end wall 93 and a bottom wall 94 the inner pack 12 in a folded position, in the folding gusset during the formation of the sealed seams 20 . 21 folded inwards so that the folding position according to 15 . 16 is created. The folding organs 91 are stored so that they are in the plane of movement of the inner packs 12 run along during a section and then return in a retracted position to the starting position, corresponding to the dash-dotted trajectory in 14 , Training and dimensions of the folding organs 91 are chosen so that the moths formed at the ends of thighs 93 during a folding cycle, the margins of two consecutive packages 12 simultaneously edit by transverse folding movement, so edge areas of the packs 12 on both sides of the respective effective seal bar 88 ( 14 ).

Another technical peculiarity in the manufacture of the inner pack 12 implemented is the attachment of embossed lines 95 . 96 for supporting or improving fold edges 97 in the transverse direction of the inner pack 12 an inside end wall of the pack 10 limit. Through the stamping lines 95 . 96 arise when folding the film wrapping 13 sharp-edged or rectangular folding edges to limit the inner end wall 93 , The stamping lines 95 . 96 be on the continuous film web 17 according to the position of the produced inner end wall 93 attached during continuous transport of the film web 17 , Above it - in the area of a counter roll 98 - is an embossing roll 99 stored, which rests with running around embossing projections and corresponding pressure on the film web and so by material deformation the stamping lines 95 . 96 manufactures.

The relative position of the cigarette blocks 16 in the area of the film web 17 or of the film tube 18 Stabilizing connection between film and cigarette block or inner collar 14 is caused by the fact 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 method and apparatus ( 14 ) becomes the film web 17 at the top of the packs or cigarette blocks 16 supplied and the hose seam for the film tube 18 formed at the bottom. Alternatively, the film web 17 fed to the bottom of the device and the film tube are formed at the top. The cooperating aggregates, in particular the pressing or sealing aggregate 31 . 32 , is in this alternative according to the bottom of the trajectory of the cigarette blocks 16 arranged. These are reversed in their relative position, so that the inner collar 14 directed downwards.
