The invention relates to a method for producing cigarette packs, in particular of the hinge-lid type, wherein a folding turret blanks for an outer wrap of the cigarette pack of paper, thin cardboard or the like are supplied, and wherein the blanks in a folding station under at least partial erection of folding tabs the blanks are sequentially fed into pockets of the folding turret, and wherein the folding turret is cyclically driven to feed the pockets or blanks to individual stations on the circumference of the folding turret, wherein folding steps are performed on the blanks to form an at least partially folded cigarette packet, according to Furthermore, the invention relates to a corresponding device according to the preamble of claim 8. A corresponding method and apparatus are known from the DE 10 2006 047 812 A1 known.

Although known folding turrets have basically proven themselves in practice, there is nevertheless a need for improved folding turrets with which the folding steps to be carried out can be carried out as simply as possible or quickly and with material protection.

On this basis, the invention is based on the object of further developing methods and devices of the type mentioned.

A method for achieving this object comprises the measures of claim 1. It is therefore provided that in the insertion station at least one upwardly out of the pocket folding flap, in particular a front wall of the blank is moved by a Aufrichtorgan from the transport path of the package contents and held there, preferably until the insertion of the package contents is completed. In this way it can be prevented that the folding tab protruding from the pocket collides with the package contents.

As folding flaps in the context of the invention, parts of the blank which are delimited from one another are considered, for example walls (defined by folding lines), tabs, tabs or the like of the blank.

In a preferred embodiment of the method according to the invention, it is provided that the folding flap, in particular a bottom flap of the blank, is folded over a folding axis aligned tangentially with respect to the folding turret, wherein the folding element is moved radially with respect to the folding turret and that the further folding flap, in particular, a front wall of the blank is folded around an angle, in particular transversely directed to the folding axis of the first folding flap folding axis on the first folding flap.

Another special feature may be that the blank is held below the folding axis, in particular in the region of a bottom wall, at least during the folding and preferably also during the movement phases of the folding turret by negative pressure in the pocket. In this way it can be prevented that the blank is pulled out of the pocket during folding or by inertia forces or air flow during the movement phase of the folding turret. Preferably, the blank along two mutually angled, in particular transverse to each other, extending walls of the pocket is held by suction, preferably in the region of a tangential with respect to the folding turret wall of the pocket, as well as in the region of at least one substantially radially with respect to the Folding turret extending wall of the bag.

Further details of the method relate to particular features of a curved path along which the erector is moved.

An apparatus for solving the above-mentioned problem has the features of claim 8. It is therefore envisaged that in the field of insertion station movable Aufrichtorgan is arranged, for erecting upwardly out of the pocket protruding folding flaps of the blank before inserting the contents of the package. Preferably, the folding member, in particular a slide (preferably by a parallelogram) linearly in the radial direction with respect to the folding turret is moved to fold the folding flap, in particular a bottom flap of the blank.

A special feature is preferably that the folding members are actuated independently of the rotation of the folding turret, in particular by an individually controllable drive. In this way, the folding of the folding flaps can also be done at standstill of the folding turret.

Other special features concern the Aufrichtorgan, as well as the arrangement of suction channels for fixing the blank in the pocket of Faltrevolvers.

The present embodiment is explained using the example of the production of cigarette packs of the folding box type in the "side-lid pack" design, in particular according to FIG DE 10 2006 021 991 A1 , A special feature of the pack type "side-lid pack" is that a lid of the pack is not connected in the region of a large-format rear wall of the pack, but in the region of a narrow side wall of the pack via a Liniengelenkklappbar with a box part of the pack.

In the manufacture of the folding box, a package blank and a collar blank are folded as a common blank 10. For this purpose, packaging blanks on the one hand and collar blanks on the other hand supplied to a folding unit, namely a folding turret 11. The folding turret 11 is formed as usual substantially plate-shaped and gradually rotatable about a vertical axis. At the periphery of the folding turret 11, a number of pockets 12 is arranged, in each of which the blanks and then a package contents 13 are introduced.

The pack blanks for the folding box can be made according to DE 10 2006 021 991 A1 are supplied above a pocket 12 along a folding path arranged above the folding turret 11 substantially in an obliquely downward movement of a folding station 14. The relative position of the package blanks is selected so that a back wall of the package blank is aligned with the fold-in station 14.

The collar blanks are transported along a separate collar web, with a back wall of the collar blank also aligned with the fold-in station 14.

The package blanks and the collar blanks are first superimposed in the final relative position before folding into the pocket 12 and connected together, preferably with glue. In this configuration, the blank 10 cut from the blank and collar blank for the cigarette pack is inserted in the fold-in station 14 into a pocket 12 of the folding turret 11. This is done as usual in the prior art by the blank 10 is pressed by a folding member 15 through a folding channel 16 and into the pocket 12. Since both the folding channel 16 and the pocket 12 have smaller dimensions than the blank 10, a partial folding of folding tabs of the blank 10 takes place, namely a raising or pivoting of blank areas around folding lines embossed in the blank. The folding flaps may be (front, bottom, side, etc.) walls of the blank 10, or else other flaps, tabs or the like separated from one another by fold lines.

After pressing the blank 10 into the corresponding pocket 12 of the folding turret 11 is a rear wall 17 of the blank 10 in the plane of a bottom wall 18 of the pocket 12. A subsequent to the rear wall 17 bottom wall 19 of the blank 10 is erect in an upright position and is on a rear wall 20 of the bag 12. A side wall 21 of the blank 10, which adjoins the bottom wall 19 laterally, has also been erected and abuts against a corresponding upright side wall 22 of the pocket 12. The same applies to a further side wall 23 of the blank 10, which is formed on the opposite side of the bottom wall 19 from the first side wall 21. These side wall 23 abuts against an upright side wall 24 of the bag 12. A subsequent to the second side wall 23 front wall 25 and a subsequent thereto side tabs 26 of the blank 10 project upwardly out of the pocket 12 out.

After rotation of the folding turret 11 by two stations in a plug-in station 27, the package contents 13 is inserted into the open blank 10. The package contents 13 may be a cigarette block wrapped in a tinfoil wrapper.

In order to prevent the contents of the package 13 from abutting against the front wall 25 of the blank 10 projecting out of the pocket 12, the circumference of the folding turret 11 is at the periphery of the folding turret 11 stationary erecting member 29 is arranged, which moves the front wall 25 of the blank 10 from the transport path of the package contents 13. Accordingly, the erector 29 is also arranged in the insertion station 27. The erecting member 29 is arranged above the pockets 12 of the folding turret 11 and has a lid erector 30 for erecting the parts of the blank 10 protruding upward from the pocket 12. The lid erector 30 is an organ which can be moved along a cam track 31 is. The cam track 31 extends in such a way that the lid erector 30 is moved into the area above the pocket 12. This is done in such a way that the front wall 25 is moved into an upright position and outside the transport path of the package contents 13. After inserting the package contents 13, the lid erector 30 is again moved out of the region of the pocket 12 along the cam track 31.

For movement of the lid erector 30 along the cam track 31, the lid erector 30 is coupled to a straightening lever 32. The erecting lever 32 is pivotally mounted in a horizontal plane, namely on the one hand articulated on a bearing arm 33 which is mounted on a bearing 34, and on the other hand on an eccentric 35. The eccentric 35 has a rotationally driven eccentric disc 36 which on a vertical axis 37 is stored. In an eccentric bearing point 38, the erecting lever 32 is coupled to the eccentric disk 36.

The erecting lever 32 has two legs 39, 40, which are arranged at an angle to each other. At the end of a first leg 39, the lid erector 30 is arranged, which in the present case is a rod-shaped member which projects below the first leg 39 into the area above the pocket 12. At the intersection of the two legs 39, 40 of the erecting lever 32 is coupled to the bearing arm 33. At the free end of the second leg 40, the erecting lever 32 is coupled to the eccentric drive 35. In this way, the lid erector 30 describes an elongated (flat) ellipsoidal web. The direction of movement of the lid erector 30 is opposite to the direction of rotation of the folding turret 11.

The cam track 31 is oriented such that the lid erector 30 is moved at an acute angle into the pocket 12 and against the front wall 25 of the blank 10. Furthermore, the movement of the lid erecting device 30 is tuned to the cyclical drive of the folding turret 11 such that the lid erector 30 is moved into the region of the pocket 12 before the folding turret 11 stops and the wall of the blank 10 to be folded upright during the braking operation of the folding turret 11 . so that at standstill of the folding turret 11 of the erected part of the blank 10, in this case, the front wall 25 is located outside the transport path of the package contents 13.

Another particularity consists in a folding member 41 for folding over parts of the blank 10. In the present case, the part of the blank 10 is a bottom flap 42, which adjoins the bottom wall 19 of the blank.

The folding member has a slider 43, which is movable in a horizontal plane above the package contents 13, namely with respect to the folding turret 11 in the radial direction. The slider 43 is arranged such that the bottom flap 42 can be folded onto the package contents 13, by inserting the slider 43 in the radial direction in the pocket 12. The movement of the folding member 41 and the slider 43 is in Fig. 8 represented by solid lines on the one hand and dashed lines on the other.

The folding member 41 and the slider 43 is moved by a parallelogram 44 in a linear direction in the pocket 12 or pulled out to release the folded flap again. For this purpose, the parallelogram 44 has two levers 45, 46. Both levers 45, 46 are articulated on the one hand to a fixed bearing 47 and on the other hand hinged to the folding member 41. The second lever 46 is also coupled to a cam follower 48, which is guided along a cam track 49 of a control cam. By means of a return spring 50, the cam follower 48 is held on the cam track 49.

In the illustrated embodiment, each pocket 12 is associated with a separate folding member 41, which is positioned on the radially inner side of the pockets 12. The movement of the folding members 41 takes place independently of the drive of the folding turret 11, so that the folding members 41 can be moved even when the folding turret 11 is at a standstill.

Another special feature is that the blank 10 or its folding tabs are selectively held in the pockets 12 of the folding turret 11 by negative pressure. In the present case, it is provided that walls of the pocket 12 have suction holes 51 in some areas, which open into the pocket 12. In the present case, the suction holes 51 open into the pocket 12 such that the bottom wall 19 of the blank 10 and the narrow side walls 21, 23 of the blank 10 can be held by suction on the walls 20, 22, 24. This way, the bottom wall becomes 19 held below the pivoting plane of the bottom flap 42 on the corresponding wall 20 of the bag 12. The same applies to the side wall 23 of the blank 10 which is held below the pivot plane of the front wall 25 on the corresponding wall 24 of the pocket 12.

In the area of the bottom wall 19 of the blank 10 and in the region of the narrow side walls 21, 23 of the blank 10, a plurality of openings of the suction holes 51 are respectively provided in the longitudinal direction of the parts of the blank 10, which moreover also in at least two rows one above the other on the upright walls 20th , 22, 24 of the pockets 12 are arranged.

Opposite to the insertion station 27 on the folding turret 11 a Ausschubstation 52 is arranged, in which the partially finished folded packages are discharged from the folding turret 11. Here, the packages are taken over by a rotator 53, which according to DE 10 2008 010 433 the applicant can be trained.

The device described so far in substantial parts operates as follows:

The folding turret 11 is cyclically driven in cycles, the pockets 12 are gradually supplied to the individual stations on the circumference of the folding turret 11.

First, in the fold-in station 14, a blank 10 consisting of a pack blank and collar blank is pressed through the fold channel 16 into the pocket 12 of the folding turret 11 located underneath. In this case, the bottom wall 19, the narrow side walls 21, 23 and the front wall 25 are erected, the front wall 25 protrudes with the side tabs 26 up out of the pocket 12.

The as far as partially raised blank 10 is further forwarded by two stations in the insertion station 27. There is a Aufrichtorgan 29 in an elliptical path, which runs in a horizontal plane, moved into the pocket 12 (further) erection of the front wall 25 of the blank 10, such that the transport path for inserting the package contents 13 into the blank 10 is free. After insertion or insertion of the package contents 13, the erecting member 29 is again moved out of the region of the pocket 12 and the front wall 25 is released.

Furthermore, in the insertion station 27, the bottom flap 42 is placed on the package contents 13 by means of the folding member 41 and held in this position.

The pocket 12 is then moved on to a station, wherein the front wall 25 is placed on the package contents 13 by a folding member, not shown, arranged on the circumference of the folding turret 11. The folding member may be, for example, a folding switch. In this case, the bottom flap 42 is held by the folding member 41 until the front wall 25 is folded so far that a popping 42 of the bottom flap 42 is prevented. Thereafter, the folding member 41 is withdrawn.

Subsequently, further known from the prior art folding steps for folding bottom and top side tabs are performed until the folded with the exception of the side flap 26 pack is transferred to the rotator 53.

Furthermore, it should be noted that the bottom wall 19 of the blank 10 is held during the folding of the bottom flap 42 onto the package contents 13 by means of suction air on the corresponding upright (rear) wall 20 of the pocket 12. In this way it is prevented that when folding the bottom flap 42 of the blank 10 and the package contents 13 is pulled out of the bag 12. In addition, the narrow side walls 21, 23 on the corresponding (side) walls 22, 24 of the pocket 12 are held by suction to avoid pulling out of the blank 10 due to inertial forces or the air currents during the movement phase of the folding turret 11.

It is understood that the method described above or the corresponding folding turret 11 is also suitable for processing other blanks. In this respect, the assignment of the individual walls and (folding) tabs and tabs of the blank to corresponding surfaces of the pack and the walls of the bag 12 refers purely by way of example. The invention is not limited to the processing of the described blank 10 with the corresponding sequence and spatial arrangement of blank parts. In this respect, the term "folding flaps" for the individual regions of the blank 10 is generally used in the claims.

Furthermore, the following, previously not mentioned details to be considered, which are described below:

The bag 12 has according to the cuboid shape of the package to be produced correspondingly arranged walls which are arranged substantially at right angles to each other. Only the upright side walls 20, 22 of Bags 12 are slightly inclined with respect to an imaginary vertical plane, such that the cross-section of the pocket 12 widens upwards. Furthermore, the rear wall 20 of the pocket 12 is not formed closed over the entire width of the bottom wall 19 of the blank 10, but only in lateral edge regions in the vicinity of the side walls 22, 24 of the pocket 12. In between, the slider 43 engages through for folding over the bottom flap 42nd

Furthermore, a hold-down 54 is arranged along the upper edge of the side wall 22 of the pocket 12, which projects into the region of the pocket 12 and serves to support an upper edge of the side wall 21 of the blank 10.
