Description

  • The invention relates to a method for packaging cigarettes by grouping them into groups of cigarettes and wrapping them in at least one blank of packaging material (tinfoil, paper or the like), the group taking along what is kept ready in a plane transverse to the conveying direction of the group Blank is inserted into pockets of a folding turret and folded during further conveyance, the folding turret being preceded by a group revolver which conveys the cigarette groups in pockets, the groups moving axially into the pockets with the cogettes aligned parallel to the group revolver and in the transverse axial direction be pushed out of these. Furthermore, the invention relates to a device for performing the method.
  • The subject of the invention is a packaging machine, in particular for cigarettes for the production of so-called soft packs. These are usually designed as a soft cup pack, namely with an inner blank made of tinfoil, which completely surrounds the cigarette group to form a tinfoil block, and with a cup-shaped outer wrapper made of a paper blank. This outer covering is open at the top, so that the tinfoil block protrudes slightly from the cup pack. The soft pack formed in this way is usually provided with a further outer covering made of cellophane or plastic film.
  • Such packaging is produced on high-performance packaging machines. These mostly contain revolving folding revolvers for successively folding the blanks. The performance of the packaging machine is limited with intermittent folding turrets because clocked movements can only be carried out in limited speed ranges. In packaging machines with continuously revolving folding turrets or other folding conveyors, higher turning speeds are possible. However, the insertion of cigarettes or tinfoil blocks or packs into or out of the folding conveyor (s) requires special measures so that the continuity of the movement is maintained throughout. For this reason, continuously running packaging machines have only found limited use in practice.
  • In the case of cyclically driven high-performance packaging machines for cigarettes, there is an important problem in the careful handling of the cigarettes, in such a way that they are protected from severe shock loads as a result of fast-running conveying elements (tappets ...). Another type of mechanical stress for the cigarettes results from the wrapping in the inner blank, namely when it is wrapped around it in a U-shape as a result of being carried by the cigarette group being conveyed. In US-A 4 095 396 it is therefore proposed that the folding turret be preceded by a group turret which conveys the cigarette groups in pockets, the groups being pushed into the pockets in the axial direction and being pushed out of them in a transverse axial direction. By ejecting the cigarettes in their axial direction from a conventional cigarette magazine with simultaneous formation of the cigarette groups and inclusion in a group conveyor, short conveyance paths are guaranteed, since the organ (group revolver) forming the cigarette groups connects directly to the cigarette magazine can.
  • When the cigarette groups are ejected from this group revolver with the U-shaped carry-along of the blank provided, the sensitive end faces of the cigarettes are not loaded. Rather, the cut can wrap around the less sensitive long side of the cigarette group due to the transverse axial ejection of the cigarette groups.
  • The invention is based on the object of proposing a method and a packaging machine with cyclically driven folding turrets, in which, however, the output is increased considerably without the need for undesirably high switching speeds for the individual folding conveyors.
  • To solve this problem, it is proposed that the cigarette groups are conveyed in pairs in two adjacent tracks, two cigarette groups being successively insertable into a correspondingly sized pocket in the area of an insertion station such that the cigarette groups within the pocket in the axial direction Are spaced from each other.
  • A device for packaging cigarettes grouped into cigarette groups by wrapping them in at least one blank made of packaging material (tinfoil blank, paper blank or the like), the group taking one with the blank held in a plane transverse to the conveying direction into pockets Folding turret can be inserted and the blank can be folded when it moves further, and the cigarettes in the area of a group turret upstream of the (first) folding turret can also be combined into individual cigarette groups in pockets and in the area of an insertion station in the pockets in the axial direction and in the area of one Extending station in the transverse axial direction can be pushed out of one of the pockets, is achieved according to the invention in order to achieve the object described above, in that in the region of the inserting station the cigarettes can be inserted in several pockets at the same time, which in the axial direction for receiving two adjacent ones Cigarette groups lying in each other are dimensioned and which are assigned to the side wall members (wall plunger) which can be moved to and fro in order to limit the open side (discharge opening) which is located in the radial direction and which are moved during the insertion of the cigarettes into the pockets into a laterally closing position.
  • Another bottleneck exists in high-speed cigarette packaging machines in the area of the delivery of the cigarettes from the cigarette Magazine to an organ for the formation of cigarette groups. The cigarettes are ejected from magazine shafts by means of reciprocating pushers and are inserted into receptacles (pockets) of the group revolver. It must be taken into account that there is sufficient time for the plunger to move back and forth and for a sufficient number of cigarettes to fall in the magazine shafts. Especially in multi-lane, z. B. two-lane operation of the packaging machine, it is problematic to do justice to the above technical contradictions.
  • In the invention, adequately dimensioned cycle times are guaranteed by a special design of the magazine shafts or of shaft groups assigned by a cigarette group and by a training or arrangement of the pockets for receiving the cigarette groups in the group revolver. The special feature is that a plurality of pockets of the group revolver can be loaded simultaneously via a corresponding number of shaft groups, but on the other hand it is ensured that the cigarettes in the individual magazine shafts can fall down due to their own weight when the plunger is retracted. This is made possible by a fan-like arrangement of the shaft groups, which are therefore only slightly inclined with respect to the vertical. On the other hand, a special relative position of the group receptacles or pockets of the group revolver is provided, such that the pockets, preferably four, each located in a loading station are each directed transversely to the assigned shaft groups. The longitudinal median plane of the pockets is oriented at an angle to both the radial and the tangential.
  • In order to enable the cigarettes to be inserted in the axial direction and to be moved out axially, the pockets of the group revolver are open at least on one axially directed side and on the side lying outside in the radial direction. A limitation or guidance or holder for the cigarettes is provided here during the filling and during the subsequent transport.
  • The formed cigarette groups are ejected in the area of an ejection station in a horizontal plane at a distance below the horizontal central plane of the group revolver and inserted into the pocket of a first folding revolver with the aid of a transverse cut. In the area of the same, parts of the blank are folded; additional blanks during ejection or in the area of a subsequent folding path.
  • This is followed by a second folding turret for attaching the outer cover (paper cut). This is inserted into the empty pocket prior to the introduction of the already completed tinfoil block in a U-shape. The tinfoil block is therefore inserted into the preformed paper blank that is fixed in the pocket.
  • Following this second folding turret, a packing tower is provided for receiving the finished packs, except for an outer cellophane wrap. In the area of the same, a banderole is attached to the pack by a special banderole apparatus. In the case of a multi-lane configuration of the device, such a banding apparatus is assigned to each lane, namely offset in the transverse direction and in the longitudinal direction. Special benefits are achieved with careful handling of the cigarettes by the two-lane operation. The group turret is designed for this purpose in a special way, namely with double-wide pockets in the axial direction. The pockets are filled in a special way with two groups of cigarettes lying side by side in the axial direction. In the subsequent course of the pack production, the individual measures are carried out simultaneously on the two adjacent cigarette groups or tinfoil blocks or packs.
  • The group revolver can be designed according to the invention in such a way that the cigarette groups in the pockets are exposed to lateral pressure through an elastically compressible side wall of the pockets.
  • According to an alternative embodiment of the device or method, otherwise prefabricated tinfoil blocks are fed in two lanes to a block turret, which is comparable in structure and function to the group turret and which accommodates two tinfoil blocks adjacent to one another in the axial direction. The tinfoil blocks are fed to the pockets of this block turret by means of special transfer turrets of different sizes, which are arranged in such a way that two tinfoil blocks are inserted one after the other into a pocket.

  • The exemplary embodiments and details shown in the drawings are dedicated to the production of cigarette packs 20, specifically in the form of a soft pack. In this pack construction, a cigarette group 21 consisting of three layers in the present case is first wrapped in an inner blank, namely in a tinfoil blank 22. This wraps the cigarette group 21 completely, that is, with front and bottom flaps. An outer blank, namely a paper blank 23, is cup-shaped, that is to say only with bottom tabs. The upper area is open such that a partial area of the cigarette group 21 encased in the tinfoil blank 22, namely a tinfoil block 24, protrudes from the cup of the paper blank 23.
  • The device or packaging machine for the production of such (cigarette) packs 20 consists, according to the exemplary embodiment of FIGS. 1 ff., Of several units.
  • Individual cigarettes 25 are removed from a cigarette magazine 26 to form the cigarette groups 21. In the area of an insertion station 27, the cigarette groups 21 arrive in a group revolver 28 rotating in cycles. From this area, the cigarette groups 21 are ejected in the area of an ejection station 29 and via an insertion station 30 into a first folding turret 31 together with a tinfoil blank 22 inserted.
  • In an opposite push-out station 32, the partially completed tinfoil blocks 24 enter a linear folding path 33 and from there in the area of a further push-in station 34 into a second folding turret 35 with paper blank 23 ready. The packs 20 emerging from the folding turret 35 become in the area a further fold sheet 36 is finished folded, namely with regard to bottom tabs.
  • This is followed by a collecting station 37 for the packs with upwardly directed packing towers 38 and 39. In the area of the same, special banderole devices 40, 41 are used which attach (control) banderoles 42 to the end faces of the packs.
  • The cigarette magazine 26 and group revolver 28 are designed and matched to one another in a special way.
  • The cigarette magazine 26 consists in the usual way of several cigarette shafts 43, which are intended and dimensioned for receiving the cigarettes in sealing rows 44 superimposed. The cigarettes 25 slide in these cigarette chutes 43 under their own weight down into the area of the ejection. The cigarette chutes 43 are separated from one another by thin shaft walls 45.
  • Several cigarette chutes 43 are combined to form a chute group 46, 47, 48, 49. The number of cigarette chutes 43 per chute group 46..49 corresponds to the number of cigarettes 25 per cigarette group 21 or the number of cigarettes per layer. In the present embodiment, the cigarette groups 21 consist of three layers, the middle one being offset from the outer one (saddle layer).
  • The individual shaft groups 46..49 are separated from one another by partitions 50, 51 and 52. The very thin-walled shaft walls 45 are anchored in a lower bottom wall 53 of the shaft group 46.49. The lower cigarettes or the lower layer of the same lie on this. The shaft groups 46..49 are delimited on the sides or on the end faces by side walls 54 and 55. These are provided with openings in the lower area, through which tappets or tappet groups 56, 57, 58 and 59 are able to pass to eject a cigarette group. Each plunger group 56..59 consists of individual, upright plungers, the height of which is such that in the present case three superimposed cigarettes are ejected. The individual plungers enter the area between the shaft walls 45.
  • The finger-like and protruding plungers of the plunger groups 56..59 are attached to common plunger supports 60 and 61 on one side. The upper plunger groups 56 and 57 are attached to the upper plunger carrier 60 and the lower plunger groups 58 and 59 to the lower plunger carrier 61. These are moved back and forth at the same time in the manner described above.
  • With the aid of the plunger groups 56..59 which can be moved back and forth, a cigarette group 21 is pushed out of the assigned shaft group 46..49 and pushed into a pocket 64 of the group revolver 28 with each common insertion cycle (direction arrows 62, 63). As can be seen, four pockets 64 successive in the circumferential direction of the group revolver 28 are simultaneously loaded with a cigarette group 21 in the region of the insertion station 27 simultaneously, namely with one cycle.
  • For this purpose, the group revolver 28 is arranged laterally and downwards with respect to the cigarette magazine 26. The four pockets 64 each located in the insertion station 27 are in the upper region of the group revolver 28, specifically in a position that is already in the downward movement. The upper pocket 64 assigned to the shaft group 46 is in a position following the highest position, while the lower one, the shaft Pocket 64 assigned to group 49 has almost reached the horizontal central plane of group revolver 28.
  • The pockets 64, which are rectangular in cross-section in accordance with the cross-section of a cigarette group 21, are aligned axially parallel with their longitudinal extension (longitudinal direction of the cigarettes 25). With the rectangular cross-section, they are arranged in a special relative position such that each pocket 64 is directed exactly transversely to the lower region of the associated shaft group 46.49. The partially curved shaft walls 45 are directed in the ejection area of the cigarettes 25 perpendicular to the bottom wall 53 and perpendicular to the pocket 64 or to the side walls 65 and 66 thereof.
  • For this purpose, the pockets 64 are directed with their longitudinal center plane (parallel to the side walls 65, 66) at an angle both to the radial plane and to the tangential plane of the group turret 28, namely in an oblique position. This relative position on the one hand and the alignment of the shaft groups 46..49 on the vertical result in their design. As can be seen, the chute groups 46.49 are fan-shaped with slight angular deviations with respect to the vertical, so that the downward movement of the cigarettes 25 in the cigarette chutes 43 is not disturbed. Only through this special design of the shaft groups 46.49 on the one hand and the relative position of the pockets 64 on the other hand can four pockets 64 be loaded simultaneously from assigned shaft groups 46.49 of a common cigarette magazine 46 without an intermediate conveyor element.
  • The cigarettes 25 are pushed into the pockets 64 in the longitudinal direction thereof, and are directed towards the tappet groups 56..59 with any filters 67 that may be present. In the area of the ejection station 29, the cigarettes 25 or the cigarette groups 21 are conveyed transversely axially out of the pockets 64 of the group turret 28. This requires a special design of the pockets 64. This is because they are not only open on one axial side (insertion opening 68), but also on the outer side in the radial direction (extension opening 69). The insertion opening 68 and extension opening 69 correspond to the full cross section of the pocket 64.
  • The pockets 64 are arranged in a turret ring 70 of the group turret 28 at the angular position described. A passage opening 71 that is smaller (narrower) than the cross section of the pocket 64 is formed on the side opposite the ejection opening 69. This is intended for the entry or passage of an ejection slide 72 in the area of the ejection station 29. By means of this ejection slide 72, which can be moved back and forth in the horizontal plane, the entire cigarette group 21 is conveyed out of the pocket 64 transversely axially via the ejection opening 69 and pushed into a pocket 73 of the first folding turret 31 as this movement continues.
  • The extension station 29 is offset in height relative to the horizontal longitudinal center plane of the group turret 28 (drive shaft 74), such that the pocket 64 located in the extension station 29 is directed horizontally. As a result, the folding turret 31 is also offset with respect to the group turret 28. The ejection slide 72 is provided with a slide head 75, the contour of which corresponds to the contour of the facing long side of the cigarette group 21, so that the three edge-side cigarettes are detected together by the ejection slide 72 or the slide head 75.
  • The cigarettes 25 of the cigarette groups 21 are secured in the pockets 64 against relative displacements and against falling out through the ejection opening 69. In the exemplary embodiment in FIGS. 1 ff., Each pocket 64 is assigned holding elements attached to the turret ring 70, namely pivoting holding fingers 76 and 77. These are each mounted above and below or next to the pockets 64. In the swiveled-back position (in the area of the insertion station 27), the holding fingers 76, 77 lie outside the area of the ejection opening 69, as well as in the area of the ejection station 29. In the holding position, the outer edge-side cigarettes 25 of the cigarette group 21 (outer layers) are detected by a holding finger 76, 77. The ends of which are adapted to the contour of the cigarettes 25.
  • In the area of the insertion station 27, the open side of the pockets 64 is delimited by stationary, reciprocable wall plungers 78. These plate-shaped organs enter the ejection opening 69 of the four pockets 64 located in the insertion station 27 with an exact relative position such that they are precisely limited to the dimensions of the cigarette group 21. As a result, the pockets 64 have a continuously closed cross section in this area. When the group revolver 28 is transported forward by one switching cycle, the wall plungers 78 are withdrawn. The revolving holding fingers 76, 77 only come into effect outside the insertion station 27.
  • The units in this packaging machine are designed for double-lane operation to increase performance. This means that two packs are produced side by side at the same time.
  • The group turret 28 is also set up and designed for double-track operation. This means first of all that the pockets 64 are dimensioned in the axial direction in such a way that two cigarette groups 21 are accommodated side by side in each pocket. As shown, the pockets are designed like a blind hole with a insertion opening 68 on one side. A cigarette group 21 a which is first inserted into the pocket 64 is conveyed to the end of the pocket 64. The second cigarette group 21 remains in a position adjacent to the insertion opening 68. In the present exemplary embodiment, the ends of the cigarettes 25 are flush with the side surface of the group revolver 28. In the case of filter cigarettes, the cigarette groups 21 with the filter 67 inserted backwards into pocket 64.
  • The loading of the group revolver 28 with cigarette groups 21 is matched in a special way to the functional sequence. The group revolver 28 switches in each case by a cycle corresponding to the spacing of the pockets 64. The number of switching cycles is, for example, 600 per minute. During a standstill, the same number of cigarette groups 21 are inserted into the four pockets 64 in the area of the insertion station 27. Cigarette groups 21a are inserted into the two upper pockets 64a and 64b, which lie behind in the direction of rotation of the group revolver 28, up to the end of the pocket 64a and 64b. The assigned tappets or tappet groups 56 and 57 are dimensioned accordingly and cover a conveying path up to the aforementioned end position of the cigarette groups 21 a.
  • The pockets 64c and 64d are filled with cigarette groups 21b, which are placed in the entry area of the pockets 64c, 64d, so that the latter pockets are filled by this insert into two cigarette groups 21a, 21b.
  • The group turret 28 is advanced by one stroke after the tappet groups 56..59 are withdrawn. In the next position, no cigarette groups -21 are inserted into the (four) pockets 64 located in the insertion station 27. Rather, the cigarettes 25 in the cigarette shafts 43 of the shaft groups 46.49 have time after the plunger groups have been completely withdrawn to fall into the lower position. Only after switching the group turret 28 again are there two empty and two pockets 64a..64d which are already provided with a cigarette group 21a and are ready to receive in the area of the insertion station 27. The insertion process for all (four) pockets 64 can now be repeated.
  • The cigarette groups 21a, 21 are spaced apart from one another in the pockets 64, which are matched to the further packaging process. In the area between the group turret 28 and the (first) folding turret 31, a double-wide tinfoil cut is fed in transversely to the horizontal conveying direction in the area of a packing web 80. The blank 22 is separated from a continuous material web 81 by cutting knives 82. The packing web 80 acts here through its boundary walls like a folding mouthpiece. Due to the relative movement of the cigarette group 21 through the packing web 80 into an adjacent pocket 73 of the folding turret 31, the blank 22 is carried along with a U-shaped covering of the front area of the cigarette group 21.
  • The tinfoil blank 22 is provided with laterally protruding folding tabs, namely upper and lower longitudinal tabs 83, 84 and corner tabs 85, 86. The longitudinal tabs 84 and corner tabs 86 in the area between the adjacent cigarette groups 21 are initially connected to one another so that a continuous blank is formed in the transverse direction. For this reason, the distance between the cigarette groups 21 a, 21 of a pocket 64 corresponds to twice the width of the longitudinal tabs 84 and corner tabs 86 of the blank. In the further course of the packaging process, the double blank 23 is divided into two individual blanks along a longitudinal dividing line 87.
  • The holding members for the cigarette groups 21 in the pockets 64 are set up for the double-track dimension. Two pairs of holding fingers 76, 77 are arranged on a rotary shaft 88 on both sides of a pocket 64. The reciprocating rotary movements thereof are controlled by a fixed cam 89, in the control groove 90 of which a feeler wheel 92 connected to a crank arm 91 runs. Due to the shape of the control groove 90, the movements of the holding fingers 76, 77 are carried out in the manner described.
  • The revolver ring 70 gives the group revolver, which is open on one side, a pot-like shape. Within this hollow body, in the region of the ejection station 29, two ejection slides 72 which are located next to one another and are movable at the same time are arranged. Corresponding to this, each pocket 64 is provided with two slit-like passage openings 71 lying next to one another for the ejection slide 72 in the region of the cigarette groups 21 a, 21 b. The through openings 21, which are closed in cross section, have a slightly smaller height than the corresponding dimension of the pocket 64.
  • An embodiment of the group revolver 28 modified in relation to the design of the pockets is shown in FIGS. 6 and 7. With regard to the orientation of their longitudinal center plane, the pockets 64 have the same relative position within the group turret 28 as in the previously described exemplary embodiment. The difference is that the cigarette groups 21 in the pockets 64 are subjected to lateral pressure to format the cigarette group.
  • For this purpose, one of the side walls of the pocket 64 is designed to be movable in the sense of narrowing or widening the pocket 64. In the specific exemplary embodiment, the side wall is part of a pressure lever 93 which is pivotably mounted on a pivot bearing 94 within the group turret 28 as a one-armed lever. A radially outer wedge piece 95 forms the side wall of the pocket 64 that lies forward in the direction of rotation.
  • The pivotable pressure lever 93 and thus the wedge piece 95 are under elastic pressure in the direction of a reduction in the width of the pocket 64. In the present case, a pressure spring 96 is assigned to the pressure lever 93 in the area of the wedge piece 95. This is supported on a likewise movable, controllable actuating element, namely on an actuating lever 105, which is likewise single-armed here. This is also pivotably mounted in the region of the pivot bearing 94 and is controlled by a cam roller 107, which runs within the group revolver 28, via a cam track 107.
  • By appropriately designing the cam track 107, the operating lever 105 is moved so that the cigarette groups 21 during transport from the insertion station 27 to the end thrust station 29 is loaded with pressure by the wedge piece 95. The actuating lever 105 is applied to the pressure lever 93 by compressing the compression spring 96.
  • The actuating lever 105 with a corresponding length has a further function, namely the holding of the cigarettes or a cigarette located at the facing corner of the cigarette group 21 instead of the holding finger 77 missing in this exemplary embodiment on the side of the pressure lever 93. The free end of the actuating lever 105 is provided for this purpose with a laterally directed nose 108 comprising the corner-side cigarette.
  • In the area of the extension station 29, the actuating lever 105 is pivoted back into an initial position, relieving the pressure of the compression spring 96. As a result, the pressure lever 93 with the wedge piece 95 is also lifted off the cigarette group 21 with a corresponding enlargement of the pocket 64. The cigarette group can now be pushed out in the manner described.
  • As can be seen from FIG. 7, the pressure lever 93 and the actuating lever 105 extend over the full length of the pocket 64 dimensioned for the reception of two cigarette groups 21. The pivot bearing 94 is also located outside the area of the turret ring 70 like the cam track 107.
  • When the holding fingers 76, 77 or the actuating lever 105 and the pressure lever 93 have moved into the retracted starting position in the region of the extension station 29, cigarette holders 97, 98 come into operation. These are elongated, rod-shaped holding members which - assigned to each cigarette group 21 a, 21 b of a pocket 64 - enter the ejection opening 69 of the pocket 64 from the sides. For this purpose, the cigarette holders 97, 98 are brought into their position from a lateral position (dash-dotted lines in FIG. 5) by transverse movement and then an arc-shaped approach to the group revolver 28. A portion of each cigarette holder 97, 98 is then on the outer side of a cigarette group 21 a, 21 b. The surface facing the cigarettes is formed with a profile which corresponds to the lateral contour of the cigarette group, so that it is supported in a form-fitting manner. The cigarette holders 98 are moved in the opposite direction when the cigarette groups 21a, 21b are ejected, and accordingly run with the cigarette groups 21a, 21 along a path of the same before they are pulled off laterally. The supporting function of the cigarette holder 97, 98 is maintained beyond the transverse plane predetermined by the blank 22 provided, so that the cut 22 is carried along by the cigarette group during the initial phase by the cigarette holder 97, 98, which thus counteracts the cigarettes Protect excessive stress from the drawn blank 22.
  • The blank 22 is held ready in such a position relative to the packing web 80 that there is an asymmetrical position with respect to the cigarette group in the pocket 73 of the revolver 31. A blank leg 99 of the blank 22 protrudes from the pocket 73 in the radial direction. When the folding turret 31 moves further in the direction of rotation shown, this cutting leg 99 is folded over by a fixed, externally extending, curved guide wall 100 and placed in a rearward-facing position. When it is ejected from the pocket 73 in the region of the ejection station 32, part of the cutting leg 99 is folded over into the radially directed plane, namely to form part of the front or rear side of the inner casing.
  • The packing web 80 and correspondingly the pockets 73 of the first folding turret 31 are divided in the central region by a partition 101 or by a folding web 102. This results on the one hand in precise movement paths for the cigarette groups. Canting is avoided. On the other hand, the central flaps, that is to say between the cigarette groups 21 a, 21 b, are partially folded by the end faces of the folding web 102, namely the corner flaps 86. On the outer sides, the pocket 73 is provided with corresponding folding webs 103 which cover the outer ones Fold the corner flaps 85 into their position during the insertion of the cigarette groups 21 with the blank 22 into the pocket 73 and fix it laterally.
  • After the ejection slide 72 has been retracted into the starting position, the cigarettes in the pocket 73 are held in position on the radially outer side by a further holding member. It is an arcuate support plate 104 which can be moved back and forth concentrically to the folding turret 31 along the circumference thereof. 2 shows the support position. When the turret 31 moves further, the support plate 104 is carried along during a partial movement before it returns to a lower starting position by means of a concentric rotary movement. This ensures that the not yet wrapped cigarettes are supported in the pockets 73 in the entire circumferential area of the cigarette group 21.
  • The cigarette groups 21, which are partially enveloped by the tinfoil blank 22, are transported by the folding turret 31 to an ejection station 32 opposite the insertion station 30. Here the two adjacent cigarette groups 21 a, 21 b of a pocket 73 are jointly ejected from it, namely by means of two interconnected and jointly movable plungers 109, 110. The cigarette groups, each with an associated (partial cut 22, now arrive into the fold sheet 33, in which the longitudinal tabs 83 and 84 projecting in the middle area and laterally projecting are folded into the plane of the end faces by means of lateral folding members, namely fold switches 111. As shown in FIG. 8, the lower longitudinal tabs 83 become the fold tabs 111 , 84. Upper longitudinal flaps are subsequently moved upwards by cutting the cigarette groups with a blank by a lifting punch 112 relative to a stationary folding member, namely lateral folding walls 113 and a common central folding wall 114, also folded in the face. The folding sheet 33 accordingly consists of two sections offset in height. The upper section also forms the insertion station 34 for the subsequent second folding turret 35. The cigarette groups 21 are now completely encased in the tinfoil blank 22 and accordingly form a tinfoil block 24. The two tinfoil blocks 24, which are now adjacent, are separated by one common reciprocable slider 115 inserted into a pocket 116 of the folding turret 35 in the radial direction.
  • The folding turret 35 is used to attach and (partially) fold the outer paper blank 23. In the present case, this is inserted into the pockets 116 in the direction of rotation of the revolver in front of the insertion station 34, specifically in a lower region by means of a radial upward movement. The paper blanks 23 are separated from a paper web 117 in the region of a horizontal feed path 118 by knife rollers 119. A pusher 120, which can be moved up and down, introduces the paper blank 23 into the pocket 116, which is open at the bottom, with a U-shaped deformation. The pusher 120 is provided with a suction hole 121 on the end face for fixing the paper blank 23. The pocket 116 is also provided on its side surfaces with suction bores 122 for holding the paper blank 23 in the pocket 116 without changing the U-shaped shape. The paper blank 23 and accordingly the pockets 116 and the pusher 120 are dimensioned in the axial direction in such a way that two tinfoil blocks 24 lying next to one another at a distance can be processed simultaneously.
  • In the area of the insertion station 34, the two tinfoil blocks 24 are accordingly inserted into a U-shaped (double-wide) paper blank 23 that is already in the pocket 116.
  • Lateral protruding flaps 123 and 124 of the paper blank 23, which protrude laterally from the pocket 116 in the radial direction, are held in a funnel-widening, ie diverging, position. For the lower, shorter side folding tab 123, a guide finger 125 is pivotally mounted below the conveying plane of the tinfoil blocks 24. The guide finger 145 is moved from a lower starting position (dash-dotted lines) into an oblique guide position, which facilitates the introduction of the tinfoil blocks 24, in which the associated side-folding tab 123 is pressed slightly downward.
  • The opposite, upper side folding tab 124 is held on a stationary, circular arc-shaped guide wall 126 by suction bores 127.
  • After the tinfoil blocks 24 have been inserted into the U-shaped paper blank 23 in the pocket 116, the lower side folding flap 123 is first folded into the plane of the side face of the pack by means of a folding web 128 which can be moved upward in the tangential plane. The folding turret 35 is now advanced by one cycle, with the folding web 128 initially being moved along until the side folding tab 123 reaches the area of the guide wall 126 and is held by it. As a result of the relative movement of the upper side folding tab 124, the guide wall 126 has already folded over into the plane of the side surface of the pack.
  • The side folding tabs 123, 124 are connected to one another by gluing. For this purpose they are provided with hot melt markings which are activated by stationary stamps 129 and 130 which can be moved towards the packs in the pockets 116. At the same time, the side folding tabs 123, 124 are connected to one another by the pressure exerted.
  • In the area of an extension station 131 opposite the insertion station 34, the tinfoil blocks 24 provided with the paper blank 23 are pushed out of the pockets 116 in the horizontal plane and radial direction by means of correspondingly designed sliders 132 and inserted into the folding web 36. Here, projecting, lower longitudinal tabs are folded over on one side to form the bottom by folding switches 133. When the packs 20, which have now been completed, move upward again, the upper longitudinal tabs 134 are folded over into the pack tower 38 or 39 into the plane of the bottom wall.
  • In the area of the packing towers 38, 39 assigned to each web, banderoles 42 are attached to the packs 20 in the area of the exposed end face of the tinfoil blocks 24. The banderoles 42 extend transversely across the end face of the package 20 in such a way that a middle part 135 abuts the end face and legs 136 on the front and rear walls.
  • As can be seen from FIGS. 10 to 13, the packs 20 are arranged in the region of the folding web 36 in such a way that the upper end faces 137 to be provided with the band 42 face the two rows of packs 20 to the same side. In the conveying direction, partial webs 138, 139 of the folding web 36 lying side by side end with an offset. The partial web 138 is longer in the conveying direction than the partial web 139. The packing towers 38, 39 are thus arranged offset from one another. This creates a recess 140 in the region of the partial web 139, in which the banding apparatus 40 assigned to the packing tower 38 is accommodated. The second banding apparatus 41 is located on the side next to the associated packing tower 39.
  • Each band apparatus 40, 41 consists of a transmission wheel 141 as the most important organ. Individual banderoles 42 are each taken from an associated banderole magazine 142 by a known unwinder 143. The banderoles 42 are placed on the circumference of the transmission wheel, with intervals and with a predetermined exact comparative position.
  • During the transport of the bands 42 on the transfer wheel 141, the side to be connected to the packs 20 is turned outwards. This is provided with glue, specifically by a segment wheel 144, the circumference of which is provided with glue by a glue roller 145 from a glue container 146.
  • To transfer the bands 42 to the packs 20, the transmission wheel 141 is meh reren, in the present case provided five transmission elements, namely radially movable transmission plungers 147. These are fork-shaped with two side support legs 148 and 149. Each support leg 148, 149 is seen with ver opening on the radially outer receiving surface suction bores 150. The support legs 148, 149 are arranged at a distance from one another (in the circumferential direction) and the bands 42 are placed on the circumference of the transmission wheel 141 in such a way that the ends of the bands 42 are gripped by the suction bores 150 of the support legs 148, 149 and on the transmission wheel 141 are fixed.
  • Between the support legs 148, 149 there is a pressure stamp 151, which is designed in the form of a circular arc on the outside. This fills the circumferential distance between the support legs 148, 149. The pressure plunger 151 can be moved in the radial direction, relative to the support legs 148 149 and is supported on a radially inner support body 152 which connects the support legs 148, 149 to one another via a compression spring 153. The support body 152 is wedge-shaped in the radially inner region. A lateral, cross-sectionally shaped extension 154 of the support body 152 protrudes from the area of the transmission wheel 141 and is used to support an actuating member in the form of a slide 155 with actuating legs 156, 157. The latter receive contact with the respective extension 154 of the two transmission wheels 141. The Slider 155 can be moved back and forth while simultaneously taking along the transmission tappets 147 of the two transmission wheels 141 that are in the transmission position.
  • In the transfer position, the banderole 41 is transferred to the package 20 held in a corresponding relative position by radial movement of the transfer plunger 147 or the two support legs 148, 149. The middle part 135 is thereby in contact with the end face 137 of the packs, while the legs 136 are pressed against the front and back of the pack by the support legs 148, 149. For this purpose, the support legs 148, 149 are at a distance from one another which corresponds approximately to the width of the package 20, so that the support legs 148, 149 are moved along the front and rear sides of the package 20 by pressing the transfer plunger 147 radially while pressing the legs 136 of the Banderole 42.
  • Due to the movement of the transfer plunger 147 described above, the band 42 is also pressed in the region of the central part 135 due to the tension in the longitudinal direction on the end face 137. The compression spring 135 is compressed (Fig. 12). When the slider 155 returns to the starting position (dash-dotted lines in FIG. 12), the transfer ram 147 with the support legs 148, 149 is moved back into the starting position as a result of the pressure spring 153 being relaxed. The compression spring 153 is supported on the support body 152 extending in the circumferential plane of the transmission wheel 141.
  • The banderoles 42 are transferred to the pack 20 held ready for this purpose in the plane of the folding web 36 or the partial webs 138, 139. In this area (pack tower 38, 39) a lifting stamp 158 acts as a floor limitation of the partial webs 138 Stamp plate 159 is provided with a cutout 160 on the side facing transmission wheel 141. The transfer plunger 141 or the lower support leg 149 enters this during the transfer of the band 42. After the support legs 148, 149 have been pulled back, the now completed package 20 is raised by the lifting ram 158, specifically under an already formed stack of packages 161. This is carried by support webs 162, 163, which each grip the lower package 20. The supporting webs 162, 163 can be moved transversely to the pack tower 38, 39, namely out of the area of the pack stack 161, so that the lower pack can be fed to the pack stack 161. Through the cutout 160 in the stamp plate 159 and through a further, opposite cutout 164, the supporting webs 162, 163 can, after supplying a (lower) pack to the pack stack 161, grasp it on the underside before the lifting punch 158 is moved back down to the starting position.
  • The upper packs 20, in each case groups of two packs lying one above the other, are conveyed out of the pack tower 138, 139 by cross slide 165 into a horizontal pack conveyor 166.
  • An alternative solution with regard to the formation of tinfoil blocks 24 and the introduction thereof into the further packaging process is shown in FIGS. 14 to 16.
  • In this approach, otherwise manufactured tinfoil blocks 24 are fed in pairs in two parallel tracks by block conveyors 167 and 168. The tinfoil blocks 24 are in the area of these block conveyors 167, 168 in the horizontal plane and at a distance from one another by suitable conveying elements, for. B. chain conveyor transported.
  • A transfer turret 169, 170 is assigned to each block conveyor 167, 168. These are arranged with their axes of rotation (shaft 171) in the conveying direction of the tinfoil blocks 24. The transfer revolvers 169, 170 accordingly rotate in planes transverse to the block conveyors 167, 168, specifically in the direction of rotation represented by arrows 172.
  • The transfer turrets 169, 170 are used to transfer the tinfoil blocks 24 from the block conveyors 167, 168 to a common block turret 173. This is designed in a similar manner to the group turret 28 of the exemplary embodiment described above. Similarly, pockets 174 are arranged along the circumference of block turret 173 in an inclined position, namely at an angle of the median plane between the tangent and the radial. The tinfoil blocks 24 are introduced into the pockets 174 in the axial direction via lateral insertion openings 175. These are designed and dimensioned in the axial direction - similar to the group revolver 28 - such that two tinfoil blocks 24a and 24b ne 174 in a pocket next to each other, with a distance between them.
  • The transfer revolvers 169, 170 are designed and arranged such that a tinfoil block 24 can be picked up and a tinfoil block can be transferred to the turret 173 at the same time during a standstill phase. For this purpose, the transfer revolvers 169, 170 are provided with pockets 176 and 177, which are temporarily brought overlapping with one or the other block conveyor 167, 168 as well as with one pocket 174 of the block revolver 173.
  • The transfer revolvers 169, 170 are of different sizes, namely they are dimensioned with different diameters. The smaller transfer turret 169 assigned to the block conveyor 167 is provided with three pockets 176 which, parallel to the tangent at a distance from it, are designed as a chamber which is closed in the circumferential direction or as a channel which is closed in cross section and open at both ends. The three pockets 176 are accordingly arranged at the same angles to one another and at the same distances from one another.
  • At a certain position of the transfer turret 169 (FIG. 14) there is a lower, horizontally oriented pocket 176 in the path of movement of the block conveyor 167, so that a tinfoil block 24 can be inserted into the lower pocket 176 by appropriate conveyance. Another pocket 176 of the transfer turret 169 is congruent with a pocket 174 of the block turret 173, so that the pack or the tinfoil block 24 can also be transferred from the pocket 176 into the pocket 174 by axial movement. For this purpose, the transfer turret 169 is slightly offset in the direction of rotation of the block turret 173 from its vertical center plane.
  • The second transfer turret 170 lies on the other side of the vertical center plane of the block turret 173 at a greater distance therefrom. The four pockets 177 arranged at right angles or parallel to one another are also matched to the block conveyor 168 and to a pocket or a specific relative position of a pocket 174 of the block turret 173. . As shown, there is a lower, horizontally located pocket 177 in the path of movement of the tinfoil blocks 24 of the block conveyor 168, so that the tinfoil block 24 is conveyed into the pocket 177 by axial conveyance. The next vertically oriented pocket 177, which follows in the direction of rotation, is congruent with a pocket 174 of the block turret 173 located in this position. The axial turret block 24 can therefore also be transferred to the block turret 173 by renewed axial displacement.
  • For the (simultaneous) transfer of a tinfoil block 24 from the transfer turrets 169, 170 to the block turret 173, plungers 183, 184 are used, the two transfer turrets 169, 170 or the pockets located opposite each other to a pocket 174 of the block turret 173 176 and 177 are assigned.
  • In the present exemplary embodiment, too, the tinfoil blocks 24a, 24b of a pocket 174 of the block turret 173 are inserted in successive work cycles. Due to the arrangement and design of the transfer revolvers 169, 170, a pocket 174 remains free between the filling positions. Accordingly, while the turret block 173 is driven with the maximum number of cycles, a tinfoil block 24 is inserted every second switching cycle or when the turret 173 is at a standstill, first in the area of the larger transfer turret 170, the tinfoil block to be moved to the inner end of the pocket 174 24a and then in the area of the transfer turret 169 the second tinfoil block 24b facing the insertion opening 175. Here too, the insertion movements are slower and compatible with the cigarettes.
  • The tinfoil blocks 24 introduced into the pockets 174 in the axial direction are pushed out of the pocket 174 in the region of an ejection station 178 in the axial direction or approximately axial direction, at least transversely axially to the cigarettes, and inserted into a pocket 179 of a folding turret 180. For this purpose, a double slide 181, which can be moved back and forth within the block turret 173, is provided, which enters the pocket 174 via the internal ejection opening 182 in the region of the tinfoil blocks 24a, 24b. During the transfer movement of the tinfoil blocks 24a, 24b into the folding turret 180, a paper blank 23, which is kept ready in a transverse plane, is taken with the U-shaped folding of the two tinfoil blocks 24a, 24b. The further course of the folding of this (double) paper blank 23 corresponds to the exemplary embodiment already described.
