Definitions
- the invention relates to a method for producing packs, in particular cigarette packs, having the features of the preamble of claim 1.
- the invention also relates to a device for carrying out the method.
- the gluing of folding flaps which are connected to one another by adhesive bonding is technically particularly sensitive.
- the folding flaps can be connected by means of cold glue and/or hot glue (hotmelt).
- hotmelt hot glue
- the longer curing time of the glue connection must be taken into account.
- relative displacements of the folded flaps connected to one another are possible.
- the relevant property of hot melt is the comparatively short setting time.
- the heat sensitivity of this type of glue must be taken into account in the finished packs, for example when heat is generated due to solar radiation.
- the pamphlet DE 10 52 300 shows a packaging machine in which partially folded packs with laterally protruding outer flaps (from side walls) extending 90° to form inner flaps folded in a pack-ready manner are conveyed into a turret. By moving the turret upwards, the protruding outer flaps are folded onto the inner flaps - previously glued - and connected to them by means of stationary side plates.
- the pamphlet DE 10 2011 101 672 shows packs with protruding outer flaps being conveyed along a conveyor track, glued, and the outer flaps folded onto the inner flaps by means of folding profiles in a last section of the (straight) conveyor track. The folded pack is then transferred to a transfer turret for further processing.
- the invention deals with the production of packs in which folding tabs are connected to one another by cold glue and/or by hot glue.
- the object on which the invention is based is to take into account the different properties of the types of glue used in the manufacture of packs, in particular with regard to ensuring exact shapes of the packs.
- the advantage of this method is the attachment of the glue fields, in particular glue dots, to both folding flaps to be connected to one another, i.e. in particular to the outside of an inner side flap on the one hand and to the inside of the outer side flap on the other hand, preferably in parallel, spaced rows of glue dots. It makes sense to attach the cold glue points (exclusively) to the outer side flap, preferably to the downward-facing inside of these folding flaps in their horizontal initial position. In this case, the points of hot glue are applied (exclusively) to the outside of the inner side flap, which is preferably folded into an upright, packaged position.
- the outer side tabs are then, ie after application of the glue, formed into an intermediate or pre-folded position, in particular at an (acute) angle to the horizontal starting position, ie at a (small) distance from the associated inner side tab.
- Hot glue is applied in the final phase of moving and completing the pack, in such a way that the folding flaps are brought into the final position in accordance with the pack before the hot glue sets.
- the packs are introduced into pockets of a molding unit--while maintaining the spaced relative position of the folding tabs, but for the rest of the pack to be exactly aligned. Movable folding elements then become effective in the area of the pockets, which fold the outer folding flaps into the end position and press them against the inner folding flaps.
- a special feature relates to the formation of the transport section for the packs during gluing and (partial) folding, i.e. the formation of a pack track.
- special lateral guide elements or profiled guide rails are effective, which secure the respective position of the inner and outer folding flaps and also ensure that at least the outer folding flaps can be folded without transferring pressure on the contents of the pack, especially on the cigarettes, to form a correct folding edge.
- the present exemplary embodiment deals with the production of packs 10 in which at least two folding flaps are connected to one another by glue, specifically using temporarily setting glue, in particular hotmelt, on the one hand and cold glue on the other.
- the device ensures that the pack or the folded flaps that are connected to one another are positioned precisely and appropriately for the pack during the short setting time of the hotmelt.
- the application of this technology is particularly advantageous in the production of packs 10 of the hinged box type, in particular for cigarette groups 57.
- the typical structure of these packs 10 is characterized by box part 11 and cover 12.
- the focus is on folding flaps that are connected to one another by glue, namely in particular box side flaps and lid side flaps, which form box side walls and lid side walls in the correct position for the pack.
- These folding tabs are referred to below as outer tabs 13 and inner tabs 14 .
- the folding tabs 13, 14 are part of a typical HL blank 15 for the manufacture of this type of pack.
- the outer flaps 13 are connected to a box front wall 58 or a lid front wall, while the inner flaps 14 are connected to a box rear wall 59 or to a lid rear wall.
- the present exemplary embodiments deal with two different forms of packs 10, namely on the one hand with exactly cuboid packs in which rectangular pack edges 60 are formed between the front wall 58 and rear wall 59 on the one hand and outer flaps 13 or inner flaps 14 on the other hand, which extend in the longitudinal direction of the packs 10 extend (e.g. 4 , left part).
- the type of packaging with rounded, partially circular packaging edges, namely rounded edges 61 (e.g. 4 , right part).
- the pack edges 60 are formed as a single embossed line in the area of a blank, namely a correspondingly formed HL blank 15 made of thin cardboard or similar packaging material.
- the round edges 61 are specified by a plurality of closely adjacent embossings or grooves in the blank.
- the basic structure of the device comprises a folding unit or a folding turret 16 for producing and filling the packs 10 while processing HL blanks 15.
- the folding turret 16 can be moved (cyclically) about a vertical axis of rotation.
- a cigarette group 57 wrapped by an inner blank (tinfoil block) is introduced as the contents of the pack into the partially folded HL blank 15.
- the filled pack 10 is folded until it is transferred to a pack track 17 so that the inner box side flaps and lid side flaps—inner flaps 14—are folded into the upright position in contact with the contents of the pack.
- Box front wall 58 with outer box side flaps 71 and lid front wall 73 with outer lid side flaps 72 - outer flaps 13 - are aligned in a horizontal plane, here at the top of the longitudinally transported packs 10.
- the pack track 17 adjoins the folding turret 16 in the radial direction for the transport of the incomplete packs 10.
- the shaping of folding tabs, namely the outer tabs 13, is continued.
- glue is applied to the folding tabs 13, 14 in the area of the packing web 17.
- the - unfinished - packs 10 are transferred from the pack track 17 to a forming unit for completion, in this case a forming turret 18. This can be rotated in an upright plane transversely to the direction of transport of the pack track 17 (intermittently).
- Pockets 19 are arranged along the circumference of the forming turret 18 with the function of forming a receptacle for each pack 10 .
- the packs 10 which have been completed in this area and fixed with regard to the glue connections are transferred to a discharge conveyor 20 which feeds the packs 10 to further units.
- the pack track 17 is preferably designed in such a way that the packs 10 rest with their underside—package rear wall 59—on a divided base, in particular on two track rails 21 . Between these rails 21 there is a conveyor, namely a transport belt 22 with drivers 23 for detecting a pack 10 on the back. The relative position of the packs 10 is chosen so that the lid 12 is at the front in the direction of movement.
- the folding flaps to be connected to one another ie the outer flaps 13 on the one hand and the inner flaps 14 on the other hand, are provided with glue.
- 17 gluing stations 26, 27 are set up on both sides of the pack path.
- the first gluing station 26 in the transport direction is used to transfer glue to the outer flaps 13.
- the glue is applied to the underside or inside of the outer flaps 13, ie the box side flaps 71 and the lid side flaps 72. If different types of glue are used, cold glue is applied to the outer flap 13 in this first gluing station 26 .
- the second, preferably subsequent gluing station 27 serves to transfer glue to the free outside of the inner tab 14, preferably to transfer hot glue.
- glue in particular glue dots 28, 31
- glue dots 28, 31 is applied separately to the two folding flaps 13, 14 to be connected to one another, preferably adjacent to the package edge 60 or to the rounded edge 61 of the folding flap 13, 14 in question , i.e. at a distance from a free edge - flap edge 62.
- cold glue spots 28 are applied to the outer flaps 13 .
- the row of cold glue points 28 is positioned at a greater distance from the free edge of the outer flap 13, i.e. adjacent to the already folded inner flap 14 ( 4 ).
- the spots of cold glue 28 are preferably transferred during the transport of the packs 10 by appropriately controlled glue nozzles 29 .
- a glue nozzle 29 is arranged approximately in a common transverse plane on both sides of the movement path of the packs 10, namely in an inclined position and below the plane of the outer flaps 13.
- the glue points 28 are applied 10 one after the other in the upward direction onto the outer flaps 13 transfer.
- hot glue is preferably applied, in particular hot glue (hotmelt).
- This glue is transferred to the other folding flap, namely to the inner flap 14.
- glue nozzles 30 are also arranged, preferably hot glue nozzles. These are positioned in such a way that glue is transferred (intermittently) to the outside of the inner flap 14 with the formation of hot glue spots 31 .
- These glue points 31 are also arranged in a continuous row and can be in the same vertical alignment with the cold glue points 28 or offset from them.
- the hot glue points 31 are at a greater distance from the free edge of the inner flap 14 positioned, namely adjacent to the lower folded edge 60, 61 of the inner flap 14 ( figure 5 ). Due to the positioning of the gluing station 27, the spots of hot glue 31 are applied immediately before the pack 10 is completed, in particular immediately before it enters the forming turret 18.
- the packs 10 are transported further while maintaining a (small) distance between the folding tabs 13, 14, namely in an acute-angled position of the outer tab 13 relative to the inner tab 14 ( 6 ).
- the pack is introduced into the forming turret 18 or into a pocket 19 thereof.
- the pack 10 is completed by folding the outer flap 13 and pressing it against the inner flap 14.
- the packs 10 are conveyed out of the pockets 19, in particular in an upper position ( 11 ), opposite to a preferably lower insertion station in the continuation of the pack track 17.
- at least the hot glue points have hardened, so that the pack 10 is fixed with respect to the folded flaps connected to one another by (hot) glue.
- a special technological feature is that the packs 10 are transported from the folding turret 16 to the forming turret 18 on a preferably continuously straight path and can be inserted directly into a (downward) pocket 19 of the turret 18 without any transverse displacement, in particular without a lifting movement.
- the packs 10 are aligned during transport along the pack track 17 with regard to (variable) positions of folding flaps by (fixed) guiding and adjusting elements.
- the packs 10 are guided by guide webs 24 in the area of the transversely directed outer flaps 13 .
- the preferably angular guide webs 24 are assigned to the edge edges or the flap edges 62 of the outer folding flaps 13 and form a support and an edge guide due to the angular configuration.
- the packs 10 are supported and guided by the rails 21, which are also angular in cross section, adapting to the right-angled pack edges 60 on the one hand and adapting to the round edges 61 on the other.
- the guide elements 21 and 24 are arranged relative to one another in such a way that the glue nozzles 29 can carry out the gluing of the underside of the folding tabs 13 by upwardly directed glue transfer ( 4 , 7 ).
- a device for aligning the pack parts is preferably effective, ie box part 11 and lid 12.
- This is a straightening device, namely a cap straightener 32, preferably corresponding in terms of construction and operation DE 10 2011 101 672 A1 .
- This cap straightener 32 is preferably effective in a middle area between the folding turret 16 and the gluing station 26 .
- the guidance of the outer flaps 13 up to the transfer of the packs 10 to the forming turret 18 is an innovative feature.
- the sideways directed and glued outer flaps 13 are gripped by profile rails 33, preferably following the gluing station 26 for gluing the outer flaps 13.
- the profile rails 33 grip the outer flap 13 in the area of the top and bottom. Due to the continuously changing shape of the profile rail 33 or guide surfaces for the folding tab 13, the latter is moved out of the horizontal starting position ( 4 ) With increasing approach to the inner flap 14 pivoted to the end position according to 6 .
- the profile rail 33 consists of a guide leg 34 on the upper or outer side of the folding tab 13 and a support leg 35 on the inner side.
- the support leg 35 has a dual function: a transverse or horizontal end piece extends adjacent to the inner tab 14 and serves to support the same adjacent to the free edge in the packaged position ( 8 ) following the profile 24.
- the supporting leg 35 forms an inclined support surface 63 for (an edge area) of the folding flap 13.
- the glue - cold glue points 28 - are located in a free area above the supporting leg 35.
- a supporting edge 64 covers the transition from the outer flap 13 to the front wall 58, ie the area of the pack edge 60 or the round edge 61.
- the contour is selected in such a way that the support edge 64 fits perfectly against the edge area of the pack 10.
- a guide bar 65 is attached, which follows the course of the profile rail 33 and rests on the outside of the outer tab 13.
- This (narrow) guide web 65 which is bounded on both sides by groove-like depressions, causes exact guidance by contacting the lateral folding tabs 13 and pressure according to arrow 75, in particular also a transition between the box side tabs 71 and the lid side tabs 72 with a gap 66 between these parts of the outer lobes 13 ( 9 ).
- the guide web 65 prevents a misalignment of the folding tabs 71, 72 in accordance with the dashed line.
- the guide areas formed on opposite sides of the outer tab 13 by the guide web 65 on the one hand and by the bearing surface 63 on the other hand are arranged at a distance 70 from one another, so that mutual influencing of these guide surfaces is avoided.
- the profile rails 33 are matched to the packs 10 with regard to the arrangement and, above all, with regard to the dimensions such that pressure is exerted on the edge area of the packs 10, in particular on the outer tabs 13, in accordance with the arrows in FIG 7 or. 8 .
- the tab edge 62 of the outer tab 13 rests against a support surface 67 as the end closure of the profiled rail 33, specifically directed transversely to the tab edge 62.
- a force component according to arrow 68 is transmitted to the outer tab 13 by the support. This causes a Shifting of the outer flap 13 in the area of the pack edge 60 or the round edge 61 outwards or upwards, i.e. in particular against the supporting edge 64.
- the lateral guide elements for the packs 10 or the folding flaps 13, 14 are designed in such a way that forces are specifically transmitted to the packs 10 or folding flaps 13, 14 and reaction forces are generated.
- the areas of active power transmission are marked by black arrows, e.g. B. the arrows 68, 75.
- the reaction forces generated thereby are shown as contoured arrows.
- the guide designed in the above sense for the packs 10 or the folding flaps 13, 14 preferably extends from the gluing station 26 to the gluing station 27 or beyond.
- the underside guide of the packs or their support consists of simple rails 21 without lateral guides, but at a distance from one another for the passage of the transport belt 22.
- the preferably also inclined glue nozzles 30 of the gluing station 27 are effective in a gap between the profile rail 33 and the rails 21 for transferring the dots of hot glue 31 to an area of the inner flap 14 facing the lower package edges 60 or rounded edges 61.
- An upright web 39 is provided on the inside with sloping guides, namely in continuation of the profile rails 33 with guide web 65 and opposite a contact surface 63 and also with a support surface 67, so that the described effect of the folding of the outer flap 13 in the area of the package edges 60 or rounded edges 61 continued or maintained becomes.
- the position is chosen so that the glue points 28, 31 do not have any contact with the opposite folded flap.
- a web-like top guide 40 is arranged on the top of the pack 10, namely between the profile rails 33 and between the side profiles 36.
- the guide elements namely the profile rails 33, form the side profiles 36 that act subsequently and the top guide 40 a coherent shaped body 43, which includes or covers the end section of the packing web 17—adjacent to the shaping turret 18.
- the glue nozzles 30 of the gluing station 27 are also located in the area of this shaped body 43 .
- at least the upper guide 40 is extended into the area of the (first) gluing station 26 .
- the web-like, central top guide 40 interacts with the lateral profile rails 33 and shaped bodies 43 in order to ensure exact positioning and fixing of the packs 10 during the folding process.
- the sections or areas of the pack track 17 that differ in terms of the guidance of folding flaps in particular preferably form continuous guide rails that change in terms of shape, size and contour along the conveying path of the pack track 17, in particular starting from the structure according to FIG 4 , via training in accordance with figure 5 finally to an end section or a shaped body 43 as the final shaped piece of the packing web 17.
- the transport of the packs 10 by the transport belt 22 preferably ends (roughly) in the area of the (second) gluing station 27.
- the packs 10 are transferred to the turret 18 following the gluing station 27 by a slide 41. This can be moved back and forth and grasps the packs 10 following the gluing by the glue nozzles 30 with the aid of a (fork-shaped) driver head 42 in each case on the back.
- the packs 10 are preferably pushed into the end position in the respective pocket 19 of the forming turret 18 by the slide 41 ( 12 ), i.e. in the immediate continuation of pack line 17.
- the exact position of the pack 10 in the pocket 19 is preferably ensured by a support stop 56 which cooperates with the slide 41 ( 14 ).
- the support stop 56 has a double function: On the one hand, the exact end position of the pack 10 in the pocket 19 is defined (position according to 14 ). On the other hand, the support stop 56 interacts with the slide 41 . At least during the final stages the transport movement of the slide 41 forms the support stop 56 on the opposite side by resting against the pack (lid end wall) as a counter-holder and pick-up due to the controlled return movement to the initial position 14 . In this, the precise final position of the pack 10 in the pocket 19 is guaranteed.
- the forming turret 18 is provided with a (circular) carrier or support ring 44 on which a plurality of (forming) pockets 19 are arranged in axial alignment along the circumference.
- the pockets 19 are preferably formed with a substantially C-shaped cross-sectional profile and are open at both ends.
- a radially inner pocket wall, in particular a bottom wall 45, side walls 46 and a radially outer outer wall made of outer legs 47 almost completely enclose the pack.
- a gap 48 is formed between the outer legs 47, which allows the passage of a conveying element, in this case a transverse conveyor 49, whose drivers 50 each grasp a pack 10 and convey it out of the pocket 19, preferably in the region of an upper ejected position.
- the packs 10 are transferred from the cross conveyor 49 to the discharge conveyor 20 .
- the pockets 19 of the forming turret 18 are designed in a special way, namely with inclined or diverging side walls 46. These preferably have an angular position corresponding to the position of the side tabs or the outer tabs 13 in the area of the pack track 17 when the packs 10 are transferred to the forming turret 18, so in the position accordingly 6 .
- the transfer takes place in a lower transfer position of the pocket 19, in which the packs 10 are directed with their front wall upwards.
- the pack 10 is completed by folding the outer flaps 13 in the forming turret 18 or in the pockets 19 .
- each pocket 19 is assigned folding elements which can act on the folding tabs through recesses 51 in the side walls 46 of the pocket 19 .
- Pivoting levers are advantageous, namely pressing or folding levers 52, which are mounted with a pivot bearing 53 on the support ring 44 of the forming turret 18—and are driven via this pivot bearing 53 in the sense of a pivoting movement.
- a folding head 54 is located at the free end of the folding lever 52. This has a plurality of pressure webs 55 arranged next to one another, each of which passes through one of a plurality of recesses 51 arranged next to one another in the side walls 46 and thereby rests against the folding tabs or outer tabs 13 and the folding pressure on the outer flaps 13 bis transferred to rest on the inner flap 14.
- the recesses 51 on the one hand and the folding elements or the pressure webs 55 on the other hand are preferably arranged in such a way that the pressure is transmitted in particular in the area of the (hot) glue points 31 .
- the recesses 51 and the pressure webs 55 face the outside of the pocket 19 or the outer legs 47 ( 10 ).
- the movable or pivotable folding levers 52 are actuated in such a way that immediately after the insertion of a pack 10, i.e. in particular in the lower insertion position, the folding elements 52, 54 become effective, i.e. the folding of the outer flap 13 is completed ( 7 ).
- the folding elements 52, 54 remain in the folding position during the subsequent rotary movement of the forming turret 18 up to the upper ejected position ( 8 ).
- the folding levers 52 or the folding heads 54 are pulled back so that the packs can be pushed out of the pocket 19 by the transverse conveyor 49 in the manner described. Folding levers 52 remain in the retracted position until the next package 10 is inserted.
- a further special feature of the forming turret 18 and the pockets 19 is important for the proper formation of the pack with regard to the positioning of the folding flaps 13, 14.
- These are provided with support surfaces 74, which correspond to the support surfaces 67 of the lateral guide elements in the area of the pack track 17 in terms of function and effect.
- the support surfaces 74 are designed as a radially outer delimitation of the recesses 51 and are arranged in such a way that the outer tab 13 - box side tab 71 and lid side tab 72 - find support on the support surface 74 in such a way that the pressure defined by arrow 68 the folding flap 13 is maintained until it rests against the inner flap 14.
- the support surface 74 is designed with a slope that falls towards the pack 10, so that the folding process for the outer flap 13 can be carried out while maintaining the contact between the flap edge 62 and the support surface 74 .
- An innovative special feature is the coordinated control of the movements of the packs 10 up to the transfer to the forming turret 18.
- the movement sequences are set up in such a way that the packs 10 are transferred from the pack track 17 to the forming turret 18 or a pocket 19 during one machine cycle.
- the control of the machine is particularly important in such a way that the application of the hot glue - hot glue points 31 -, the feed along the end area of the pack track 17, in particular by the slide 41, and the final folding of the pack 10, preferably in the area of the forming turret 18, during a single Machine cycle take place.
- the slide 41 is preferably driven by a servo, i.e.
- the independence of the conveying movements for the packs 10 enables the application of hot glue even during reduced machine speed and the introduction of the pack 10 into the forming turret 18 at increased conveying speed, so that the pack 10 is completed shortly after the application of hot glue.
- cold gluing can therefore be omitted.
- the drive of the slide 41 can alternatively be coupled to the machine drive. It is important to embed the gluing with hot glue in one work cycle, which always leads to the completion of the pack, namely the production of the glue connection.
- the pusher 41 grasps the pack preferably in a final phase of the (continuous) transport by the belt 22, so that the transport of the packs 10 is continued without interruption, preferably at an increased conveying speed. A collision with the belt 22 is prevented by the fork-shaped design of the driver head 42 .
- the slide 41 transports the packs 10 in a (continuous) movement cycle through the gluing station 27 to the end position within the forming turret 18.
Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Packungen, insbesondere Zigarettenpackungen, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Weiterhin betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing packs, in particular cigarette packs, having the features of the preamble of claim 1. The invention also relates to a device for carrying out the method.
Bei der Fertigung von Packungen, insbesondere von Zigarettenpackungen des Typs Klappschachtel, ist die Beleimung von durch Klebung miteinander verbundenen Faltlappen technisch besonders sensibel. Die Verbindung der Faltlappen kann mittels Kaltleim erfolgen und/oder durch Heißleim (Hotmelt). Beim Einsatz von Kaltleim ist die längere Aushärtungsdauer der Leimverbindung zu beachten. Während dieser Zeit sind Relativverschiebungen der miteinander verbundenen Faltlappen möglich. Die relevante Eigenschaft von Heißleim ist die vergleichsweise kurze Zeit zum Abbinden. Andererseits muss die Wärmeempfindlichkeit dieses Leimtyps bei der fertigen Packungen beachtet werden, beispielsweise bei Wärmeentwicklung aufgrund von Sonneneinstrahlung.In the manufacture of packs, in particular cigarette packs of the folding box type, the gluing of folding flaps which are connected to one another by adhesive bonding is technically particularly sensitive. The folding flaps can be connected by means of cold glue and/or hot glue (hotmelt). When using cold glue, the longer curing time of the glue connection must be taken into account. During this time, relative displacements of the folded flaps connected to one another are possible. The relevant property of hot melt is the comparatively short setting time. On the other hand, the heat sensitivity of this type of glue must be taken into account in the finished packs, for example when heat is generated due to solar radiation.
Es ist deshalb bereits vorgeschlagen worden, sowohl Kaltleim als auch Heißleim gemeinsam für die Verbindung der Faltlappen anzuwenden (
Die Verwendung beider Leimarten kann Probleme aufwerfen aufgrund vorzeitiger Fixierung der Heißleim-Verbindungen, bevor die Packung bzw. deren Faltlappen in eine korrekte Form gebracht worden ist bzw. sind.The use of both types of glue can pose problems due to premature setting of the hot melt joints before the package or its flap has been formed into a correct shape.

Die Erfindung befasst sich mit der Herstellung von Packungen, bei denen Faltlappen durch Kaltleim und/oder durch Heißleim miteinander verbunden sind. Die der Erfindung zugrundeliegende Aufgabe besteht darin, bei der Herstellung von Packungen die unterschiedlichen Eigenschaften der verwendeten Leimarten zu berücksichtigen, insbesondere hinsichtlich der Gewährleistung exakter Formen der Packungen.The invention deals with the production of packs in which folding tabs are connected to one another by cold glue and/or by hot glue. The object on which the invention is based is to take into account the different properties of the types of glue used in the manufacture of packs, in particular with regard to ensuring exact shapes of the packs.
Zur Lösung dieser Aufgabe ist das erfindungsgemäße Verfahren mit den Merkmalen des Anspruchs 1 ausgebildet.The method according to the invention with the features of claim 1 is designed to solve this problem.
Im Kern geht es darum, die gefalteten Bereiche der Packung und insbesondere die mit Leimfeldern - mit Leimpunkten - versehenen Faltlappen in einer exakten, packungsgerechten Relativstellung zueinander auszurichten, bevor die betreffenden Faltlappen bis zur Anlage aneinander gefaltet werden, um die Leimverbindung herzustellen. Die betreffenden Faltlappen sind - nach Aufbringen der Beleimung - zunächst mit einer Winkelstellung mindestens des äußeren Faltlappens relativ zum anderen, inneren Faltlappen positioniert. Nach dem Ausrichten der Faltlappen bzw. der gesamten (unfertigen) Packung werden die Faltlappen durch aktive Faltmaßnahme aneinandergedrückt.In essence, it is a question of aligning the folded areas of the pack and in particular the fold flaps provided with glue fields - with glue spots - in an exact, pack-oriented relative position to one another before the relevant fold flaps are folded until they rest against one another in order to create the glued connection. After the application of the glue, the relevant folding tabs are initially positioned with at least the outer folding tab in an angular position relative to the other, inner folding tab. After aligning the folding tabs or the entire (unfinished) pack, the folding tabs are pressed against one another by active folding.
Vorteilhaft bei diesem Verfahren (aber auch unabhängig hiervon) ist die Anbringung der Leimfelder, insbesondere Leimpunkte, an beiden miteinander zu verbindenden Faltlappen, also insbesondere an der Außenseite eines innenliegenden Seitenlappens einerseits und an der Innenseite des außenliegenden Seitenlappens andererseits, vorzugsweise in parallelen, beabstandeten Reihen von Leimpunkten. Sinnvoll ist die Anbringung der Kaltleimpunkte (ausschließlich) am äußeren Seitenlappen, vorzugsweise an der nach unten gerichteten Innenseite dieser Faltlappen in deren horizontaler Ausgangsstellung. Die Heißleimpunkte werden in diesem Falle (ausschließlich) an der Außenseite des vorzugsweise in eine aufrechte, packungsgemäße Stellung gefalteten inneren Seitenlappens aufgetragen.The advantage of this method (but also independently of it) is the attachment of the glue fields, in particular glue dots, to both folding flaps to be connected to one another, i.e. in particular to the outside of an inner side flap on the one hand and to the inside of the outer side flap on the other hand, preferably in parallel, spaced rows of glue dots. It makes sense to attach the cold glue points (exclusively) to the outer side flap, preferably to the downward-facing inside of these folding flaps in their horizontal initial position. In this case, the points of hot glue are applied (exclusively) to the outside of the inner side flap, which is preferably folded into an upright, packaged position.
Die äußeren Seitenlappen werden sodann, also nach Aufbringen des Leims, in eine Zwischen- bzw. Vorfaltstellung geformt, insbesondere unter einem (spitzen) Winkel zur horizontalen Ausgangsstellung, also mit (geringem) Abstand von dem zugeordneten inneren Seitenlappen. Heißleim wird in der Endphase der Bewegung und Komplettierung der Packung aufgebracht, derart, dass die Faltlappen vor dem Abbinden des Heißleims in die packungsgemäße Endstellung gebracht werden. Die Packungen werden zu diesem Zweck - unter Aufrechterhaltung der beabstandeten Relativstellung der Faltlappen, jedoch zur exakten Ausrichtung der Packungen im Übrigen - in Taschen eines Formaggregats eingeführt. Im Bereich der Taschen werden dann bewegbare Faltorgane wirksam, die die äußeren Faltlappen in die Endstellung falten und an die inneren Faltlappen andrücken. Eine Besonderheit betrifft die Ausbildung der Transportstrecke für die Packungen während der Beleimung und (Teil-)Faltung, also die Ausbildung einer Packungsbahn. Mindestens in einem Teilabschnitt, nämlich im Bereich von Beleimungsstationen bzw. während der Faltschritte der Faltlappen sind besondere seitliche Führungsorgane bzw. profilierte Führungsschienen wirksam, die die jeweilige Stellung der inneren und äußeren Faltlappen sichern und darüber hinaus bewirken, dass mindestens die äußeren Faltlappen ohne Übertragung von Druck auf den Packungsinhalt, insbesondere auf die Zigaretten, eine korrekte Faltkante bilden.The outer side tabs are then, ie after application of the glue, formed into an intermediate or pre-folded position, in particular at an (acute) angle to the horizontal starting position, ie at a (small) distance from the associated inner side tab. Hot glue is applied in the final phase of moving and completing the pack, in such a way that the folding flaps are brought into the final position in accordance with the pack before the hot glue sets. For this purpose, the packs are introduced into pockets of a molding unit--while maintaining the spaced relative position of the folding tabs, but for the rest of the pack to be exactly aligned. Movable folding elements then become effective in the area of the pockets, which fold the outer folding flaps into the end position and press them against the inner folding flaps. A special feature relates to the formation of the transport section for the packs during gluing and (partial) folding, i.e. the formation of a pack track. At least in one section, namely in the area of gluing stations or during the folding steps of the folding flaps, special lateral guide elements or profiled guide rails are effective, which secure the respective position of the inner and outer folding flaps and also ensure that at least the outer folding flaps can be folded without transferring pressure on the contents of the pack, especially on the cigarettes, to form a correct folding edge.

Das vorliegende Ausführungsbeispiel befasst sich mit der Herstellung von Packungen 10, bei denen mindestens zwei Faltlappen durch Leim miteinander verbunden werden, und zwar unter Verwendung von kurzzeitig abbindendem Leim, insbesondere Hotmelt, einerseits und Kaltleim andererseits. Die Vorrichtung stellt sicher, dass die Packung bzw. die miteinander verbundenen Faltlappen während der kurzen Abbindezeit des Hotmelt eine präzise, packungsgerechte Stellung erhalten.The present exemplary embodiment deals with the production of
Besonders vorteilhaft ist die Anwendung dieser Technologie bei der Herstellung von Packungen 10 des Typs Klappschachtel für insbesondere Zigarettengruppen 57. Der typische Aufbau dieser Packungen 10 ist durch Schachtelteil 11 und Deckel 12 gekennzeichnet. Im Fokus stehen Faltlappen, die durch Leim miteinander verbunden werden, nämlich insbesondere Schachtel-Seitenlappen und Deckel-Seitenlappen, die in der packungsgerechten Stellung Schachtel-Seitenwände und Deckel-Seitenwände bilden. Diese Faltlappen werden nachfolgend als Außenlappen 13 und Innenlappen 14 bezeichnet. Die Faltlappen 13, 14 sind Teil eines typischen HL-Zuschnitts 15 für die Fertigung dieses Packungstyps. Die Außenlappen 13 sind mit einer Schachtel-Vorderwand 58 bzw. einer Deckel-Vorderwand verbunden, während die Innenlappen 14 an eine Schachtel-Rückwand 59 bzw. an eine Deckel-Rückwand anschließen.The application of this technology is particularly advantageous in the production of
Die vorliegenden Ausführungsbeispiele befassen sich mit zwei unterschiedlichen Formen von Packungen 10, nämlich einerseits mit exakt quaderförmigen Packungen, bei denen zwischen Vorderwand 58 und Rückwand 59 einerseits und Außenlappen 13 bzw. Innenlappen 14 andererseits rechtwinklige Packungskanten 60 gebildet sind, die sich in Längsrichtung der Packungen 10 erstrecken (z. B.
Der Grundaufbau der Vorrichtung umfasst ein Faltaggregat bzw. einen Faltrevolver 16 zum Herstellen und zum Befüllen der Packungen 10 unter Verarbeitung von HL-Zuschnitten 15. Der Faltrevolver 16 ist (taktweise) um eine vertikale Drehachse bewegbar.The basic structure of the device comprises a folding unit or a
In einer Beschickungsstation des Faltrevolers 16 wird eine Zigarettengruppe 57 mit Umhüllung durch einen Innenzuschnitt (Stanniolblock) als Packungsinhalt in den teilweise gefalteten HL-Zuschnitt 15 eingeführt. Die befüllte Packung 10 ist bis zur Übergabe an eine Packungsbahn 17 soweit gefaltet, dass die inneren Schachtel-Seitenlappen und Deckel-Seitenlappen - Innenlappen 14 - in die aufrechte Stellung unter Anlage am Packungsinhalt gefaltet sind. Schachtel-Vorderwand 58 mit äußeren Schachtel-Seitenlappen 71 und Deckel-Vorderwand 73 mit äußeren Deckel-Seitenlappen 72 - Außenlappen 13 - sind in horizontaler Ebene ausgerichtet, vorliegend an der Oberseite der in Längsrichtung transportierten Packungen 10.In a loading station of the
Die Packungsbahn 17 schließt in Radialrichtung an den Faltrevolver 16 an zum Transport der unvollständigen Packungen 10. Im Bereich dieser Packungsbahn 17 wird eine Formgebung von Faltlappen, nämlich der Außenlappen 13 fortgesetzt. Des Weiteren wird im Bereich der Packungsbahn 17 Leim auf die Faltlappen 13, 14 aufgebracht. Die - unfertigen - Packungen 10 werden von der Packungsbahn 17 an ein Formaggregat zur Fertigstellung übertragen, vorliegend an einen Formrevolver 18. Dieser ist in einer aufrechten Ebene quer zur Transportrichtung der Packungsbahn 17 (taktweise) drehbar. Längs des Umfangs des Formrevolvers 18 sind Taschen 19 mit der Funktion als formgebende Aufnahme für je eine Packung 10 angeordnet. Die in diesem Bereich fertig gestellten und hinsichtlich der Leimverbindungen fixierten Packungen 10 werden an einen Abförderer 20 übergeben, der die Packungen 10 weiteren Aggregaten zuführt.The
Die Packungsbahn 17 ist vorzugsweise so ausgebildet, dass die Packungen 10 mit ihrer Unterseite - Packungsrückwand 59 - auf einer geteilten Unterlage, insbesondere auf zwei Bahnschienen 21 aufliegen. Zwischen diesen Schienen 21 befindet sich ein Förderer, nämlich ein Transportgurt 22 mit Mitnehmern 23 zum Erfassen jeweils einer Packung 10 an der Rückseite. Die Relativstellung der Packungen 10 ist so gewählt, dass der Deckel 12 in Bewegungsrichtung vorn liegt.The
Während des vorzugsweise kontinuierlichen Transports der Packungen 10 entlang der Packungsbahn 17 werden die miteinander zu verbindenden Faltlappen, also die Außenlappen 13 einerseits und die Innenlappen 14 andererseits, mit Leim versehen. Hierzu sind zu beiden Seiten der Packungsbahn 17 Beleimungsstationen 26, 27 eingerichtet. Die in Transportrichtung erste Beleimungsstation 26 dient zur Übertragung von Leim auf die Außenlappen 13. Der Leim wird dabei auf die Unter- bzw. Innenseite der Außenlappen 13, also der Schachtel-Seitenlappen 71 und der Deckel-Seitenlappen 72, aufgebracht. Bei der Verwendung unterschiedlicher Leimtypen wird in dieser ersten Beleimungsstation 26 Kaltleim an den Außenlappen 13 angebracht. Die zweite, vorzugsweise nachfolgende Beleimungsstation 27 dient zur Übertragung von Leim auf die freie Außenseite der Innenlappen 14, vorzugsweise zur Übertragung von Heißleim.During the preferably continuous transport of the
Eine (eigenständige) Besonderheit besteht also darin, dass der Leim, insbesondere Leimpunkte 28, 31, gesondert auf beide miteinander zu verbindende Faltlappen 13, 14 aufgebracht wird, und zwar vorzugsweise jeweils benachbart zur Packungskante 60 oder zur Rundkante 61 des betreffenden Faltlappens 13, 14, also mit Abstand von einem freien Rand - Lappenkante 62.An (independent) special feature is that the glue, in
Vorliegend werden Kaltleimpunkte 28 auf die Außenlappen 13 aufgebracht. Die Reihe der Kaltleimpunkte 28 ist mit größerem Abstand vom freien Rand der Außenlappen 13 positioniert, also benachbart zu dem bereits gefalteten Innenlappen 14 (
In der nachfolgenden Beleimungsstation 27 wird vorzugsweise ein anderer Leimtyp aufgebracht, insbesondere Heißleim (Hotmelt). Dieser Leim wird auf den anderen Faltlappen übertragen, nämlich auf den Innenlappen 14. Im Bereich der Beleimungsstation 27 sind ebenfalls Leimdüsen 30 angeordnet, und zwar vorzugsweise Heißleimdüsen. Diese sind so positioniert, dass (taktweise) Leim unter Bildung von Heißleimpunkten 31 auf die Außenseite des Innenlappens 14 übertragen werden. Auch diese Leimpunkte 31 sind in fortlaufender Reihe angeordnet, können in gemeinsamer Vertikalausrichtung zu den Kaltleimpunkten 28 liegen oder versetzt zu diesen. Die Heißleimpunkte 31 sind mit größerem Abstand vom freien Rand des Innenlappens 14 positioniert, nämlich benachbart zu der unteren Faltkante 60, 61 des Innenlappens 14 (
Die Packungen 10 werden nach Beleimung unter Beibehaltung eines (kleinen) Abstands der Faltlappen 13, 14 voneinander weitertransportiert, nämlich in einer spitzwinkligen Stellung des Außenlappens 13 relativ zum Innenlappen 14 (
Nach einer Teildrehung des Formrevolvers 18 werden die Packungen 10 aus den Taschen 19 herausgefördert, insbesondere in einer oberen Position (
Die Packungen 10 werden während des Transports entlang der Packungsbahn 17 hinsichtlich (veränderlicher) Positionen von Faltlappen durch (feststehende) Führungsund Justierorgane ausgerichtet. Im Bereich eines ersten Abschnitts der Packungsbahn 17 im Anschluss an den Faltrevolver 16 vorzugsweise bis zur ersten Beleimungsstation 26 sind die Packungen 10 durch Führungsstege 24 im Bereich der quergerichteten Außenlappen 13 geführt. Die vorzugsweise winkelförmigen Führungsstege 24 sind den Randkanten bzw. den Lappenkanten 62 der äußeren Faltlappen 13 zugeordnet und bilden aufgrund der winkelförmigen Ausbildung eine Auflage und eine Randführung.The
Gegenüberliegend, also im Bereich der rückseitigen bzw. unteren Bereiche, sind die Packungen 10 durch die Bahnschienen 21 gestützt und geführt, die im Querschnitt ebenfalls winkelförmig ausgebildet sind unter Anpassung an die rechtwinkligen Packungskanten 60 einerseits und unter Anpassung an die Rundkanten 61 andererseits.On the opposite side, i.e. in the area of the rear or lower areas, the
Die Führungsorgane 21 und 24 sind derart relativ zueinander angeordnet, dass die Leimdüsen 29 bei entsprechender Schrägstellung die Beleimung der Unterseite der Faltlappen 13 durch aufwärts gerichtete Leimübertragung durchführen können (
Vorzugsweise ist in diesem Bereich ein Organ zum Ausrichten der Packungsteile wirksam, also von Schachtelteil 11 und Deckel 12. Es handelt sich dabei um ein Richtorgan, nämlich einen Kappenrichter 32, vorzugsweise hinsichtlich Aufbau und Arbeitsweise entsprechend
Die Führung der Außenlappen 13 bis zur Übergabe der Packungen 10 an den Formrevolver 18 ist eine innovative Besonderheit. Im Anschluss an die Führungsstege 24 werden die seitwärts gerichteten und beleimten Außenlappen 13 durch Profilschienen 33 erfasst, vorzugsweise im Anschluss an die Beleimungsstation 26 für die Beleimung der Außenlappen 13. Die Profilschienen 33 erfassen den Außenlappen 13 im Bereich der Oberseite und der Unterseite. Aufgrund der sich fortlaufend verändernden Form der Profilschiene 33 bzw. von Führungsflächen für den Faltlappen 13 wird dieser aus der horizontalen Ausgangsstellung (
Die Profilschiene 33 besteht zu diesem Zweck aus einem Führungsschenkel 34 an der Ober- bzw. Außenseite des Faltlappens 13 und aus einem Stützschenkel 35 an der inneren Seite. Der Stützschenkel 35 hat eine Doppelfunktion: Ein quer bzw. horizontal gerichtetes Endstück erstreckt sich benachbart zum Innenlappen 14 und dient zur Abstützung desselben benachbart zum freien Rand in der packungsgemäßen Stellung (
Eine weitere Besonderheit der Profilschiene 33 ist die Ausbildung des Führungsschenkels 34 an der Außenseite des Außenlappens 13. Es werden mehrere Abstützungsbereiche gebildet, die eine verkantungsfreie Führung des Zuschnitts bzw. der Faltlappen beim Transport bewirken. Ein Stützrand 64 erfasst den Übergang des Außenlappens 13 zur Vorderwand 58, also den Bereich der Packungskante 60 bzw. der Rundkante 61. Die Kontur ist so gewählt, dass der Stützrand 64 passgenaue Anlage erhält an den randseitigen Bereich der Packung 10.Another special feature of the
Mit Abstand vom Stützrand 64, etwa mittig im Bereich des Führungsschenkels 34, ist ein Führungssteg 65 angebracht, der dem Verlauf der Profilschiene 33 folgt und der an der Außenseite des Außenlappens 13 anliegt. Dieser (schmale) Führungssteg 65, der beidseitig von nutartigen Vertiefungen begrenzt ist, bewirkt durch Anlage an den seitlichen Faltlappen 13 und Druck gemäß Pfeil 75 eine exakte Führung derselben, insbesondere auch einen Übergang zwischen Schachtel-Seitenlappen 71 und Deckel-Seitenlappen 72 mit einer Lücke 66 zwischen diesen Teilen der Außenlappen 13 (
Dieser Effekt wird dadurch erreicht, dass durch den Führungssteg 65 Druck auf die Außenlappen 13 ausgeübt wird. Die Teillappen des Außenlappens 30, nämlich Schachtel-Seitenlappen 71 und Deckel-Seitenlappen 72 werden durch den Führungssteg 65 gegen die Auflagefläche 63 gedrückt, nämlich mit einem Randbereich der Faltlappen 71, 72. Dadurch wird verhindert, dass sich die Seitenlappen 71, 72 als Teile der Außenlappen 13 entsprechend der gestrichelten Linie in
Die an gegenüberliegenden Seiten des Außenlappens 13 gebildeten Führungsbereiche durch den Führungssteg 65 einerseits und durch die Auflagefläche 63 andererseits sind mit einem Abstand 70 voneinander angeordnet, sodass eine wechselseitige Beeinflussung dieser Führungsflächen, vermieden wird.The guide areas formed on opposite sides of the
Die Profilschienen 33 sind hinsichtlich der Anordnung und vor allem hinsichtlich der Abmessungen so auf die Packungen 10 abgestimmt, dass Druck auf den randseitigen Bereich der Packungen 10, insbesondere auf die Außenlappen 13, ausgeübt wird, und zwar entsprechend den Pfeilen in
Die seitlichen Führungsorgane für die Packungen 10 bzw. die Faltlappen 13, 14 sind so ausgebildet, dass gezielt Kräfte auf die Packungen 10 bzw. Faltlappen 13, 14 übertragen und Reaktionskräfte erzeugt werden. Die Bereiche der aktiven Kraftübertragung sind durch schwarzflächige Pfeile gekennzeichnet, wie z. B. die Pfeile 68, 75. Die dadurch erzeugten Reaktionskräfte sind als konturierte Pfeile dargestellt.The lateral guide elements for the
Die im vorstehenden Sinne ausgebildete Führung für die Packungen 10 bzw. die Faltlappen 13, 14, erstreckt sich vorzugsweise von der Beleimungsstation 26 bis zur Beleimungsstation 27 bzw. darüber hinaus. Die unterseitige Führung der Packungen bzw. deren Auflage besteht aus einfachen Bahnschienen 21 ohne Seitenführung, jedoch mit Abstand voneinander für den Durchtritt des Transportgurts 22. Die vorzugsweise ebenfalls schräggerichteten Leimdüsen 30 der Beleimungsstation 27 sind in einem Zwischenraum zwischen der Profilschiene 33 und den Bahnschienen 21 wirksam zur Übertragung der Heißleimpunkte 31 auf einen den unteren Packungskanten 60 bzw.

Ein dem Formrevolver 18 zugekehrter (End-)Bereich der Packungsbahn 17 ist nochmals verändert hinsichtlich der Führungsorgane. Entsprechend der veränderten Winkelstellung der Außenlappen 13 und der hierdurch bedingten veränderten Profilbildung der Profilschienen 33 sind diese mit den Bahnschienen 21 zu einem gemeinsamen Seitenprofil 36 vereinigt (
Mindestens im Endbereich der Packungsbahn 17 ist eine stegartige Oberführung 40 an der Oberseite der Packung 10 angeordnet, nämlich zwischen den Profilschienen 33 bzw. zwischen den Seitenprofilen 36. Vorzugsweise bilden die Führungsorgane, nämlich die Profilschienen 33, die anschließend wirkenden Seitenprofile 36 und die Oberführung 40 einen zusammenhängenden Formkörper 43, der den Endabschnitt der Packungsbahn 17 - benachbart zum Formrevolver 18 - umfasst bzw. abdeckt. Im Bereich dieses Formkörpers 43 befinden sich auch die Leimdüsen 30 der Beleimungsstation 27. Vorzugsweise ist mindestens die Oberführung 40 bis in den Bereich der (ersten) Beleimungsstation 26 verlängert. Die stegartige, mittige Oberführung 40 wirkt mit den seitlichen Profilschienen 33 und Formkörper 43 zusammen, um eine exakte Positionierung und Fixierung der Packungen 10 während des Faltprozesses zu gewährleisten.At least in the end region of the
Die hinsichtlich der Führung von insbesondere Faltlappen unterschiedlichen Abschnitte bzw. Bereiche der Packungsbahn 17 bilden vorzugsweise durchgehende Führungsschienen, die hinsichtlich der Form, Größe und Kontur sich entlang der Förderstrecke der Packungsbahn 17 verändern, insbesondere ausgehend von der Struktur gemäß
Der Transport der Packungen 10 durch den Transportgurt 22 endet vorzugsweise (etwa) im Bereich der (zweiten) Leimstation 27. Die Übergabe der Packungen 10 an den Revolver 18 im Anschluss an die Beleimungsstation 27 erfolgt durch einen Schieber 41. Dieser ist hin- und herbewegbar und erfasst die Packungen 10 im Anschluss an die Beleimung durch die Leimdüsen 30 mit Hilfe eines (gabelförmigen) Mitnehmerkopfes 42 jeweils an der Rückseite. Durch den Schieber 41 werden die Packungen 10 vorzugsweise bis in die Endstellung in der jeweiligen Tasche 19 des Formrevolvers 18 geschoben (
Die exakte Stellung der Packung 10 in der Tasche 19 wird vorzugsweise durch einen Stützanschlag 56 gewährleistet, der mit dem Schieber 41 zusammenwirkt (
Der Formrevolver 18 ist mit einem (kreisförmigen) Träger bzw. Tragring 44 versehen, an dem eine Mehrzahl von (Form-)Taschen 19 in axialer Ausrichtung längs des Umfangs angeordnet ist. Die Taschen 19 sind vorzugsweise mit einem im Wesentlichen C-förmigen Querschnittsprofil ausgebildet und an beiden Enden offen. Eine radial innenliegende Taschenwandung, insbesondere Bodenwand 45, Seitenwände 46 und eine radial außenliegende Außenwand aus Außenschenkeln 47 umfassen die Packung nahezu vollständig. Zwischen den Außenschenkeln 47 wird ein Spalt 48 gebildet, der den Durchtritt eines Förderorgans, vorliegend eines Querförderers 49 ermöglicht, dessen Mitnehmer 50 jeweils eine Packung 10 erfassen und aus der Tasche 19 herausfördern, und zwar vorzugsweise im Bereich einer oberen Ausschubstellung. Die Packungen 10 werden von dem Querförderer 49 an den Abförderer 20 übergeben.The forming
Die Taschen 19 des Formrevolvers 18 sind in besonderer Weise ausgebildet, nämlich mit schräg bzw. divergierend ausgebildeten Seitenwänden 46. Diese haben vorzugsweise eine Winkelstellung entsprechend der Stellung der Seitenlappen bzw. der Außenlappen 13 im Bereich der Packungsbahn 17 bei Übergabe der Packungen 10 an den Formrevolver 18, also in der Stellung entsprechend
Im Formrevolver 18 bzw. in den Taschen 19 wird die Packung 10 durch Falten der Außenlappen 13 komplettiert.The
Jeder Tasche 19 sind demnach Faltorgane zugeordnet, die durch Ausnehmungen 51 in den Seitenwänden 46 der Tasche 19 hindurch auf die Faltlappen wirken können. Vorteilhaft sind schwenkbare Hebel, nämlich Press- bzw. Falthebel 52, die mit einem Drehlager 53 am Tragring 44 des Formrevolvers 18 gelagert sind - und über dieses Drehlager 53 im Sinne einer Schwenkbewegung angetrieben werden. An den freien Enden der Falthebel 52 befindet sich ein Faltkopf 54. Dieser weist eine Mehrzahl von nebeneinander angeordneten Druckstegen 55 auf, die je durch eine von mehreren nebeneinander angeordneten Ausnehmungen 51 der Seitenwände 46 hindurchtreten und dadurch Anlage an den Faltlappen bzw. Außenlappen 13 erhalten und den Faltdruck auf den Außenlappen 13 bis zur Anlage am Innenlappen 14 übertragen. Vorzugsweise sind die Ausnehmungen 51 einerseits und die Faltorgane bzw. die Druckstege 55 andererseits so angeordnet, dass der Druck insbesondere im Bereich der (Heiß-)Leimpunkte 31 übertragen wird. Vorliegend sind demnach die Ausnehmungen 51 und die Druckstege 55 der Außenseite der Tasche 19 bzw. den Außenschenkeln 47 zugekehrt (
Die bewegbaren bzw. schwenkbaren Falthebel 52 werden so betätigt, dass unmittelbar nach dem Einschub einer Packung 10, also insbesondere in der unteren Einschubstellung, die Faltorgane 52, 54 wirksam werden, also die Faltung des Außenlappens 13 vollzogen wird (
Für die einwandfreie Ausbildung der Packung hinsichtlich der Positionierung der Faltlappen 13, 14 ist eine weitere Besonderheit des Formrevolvers 18 bzw. der Taschen 19 von Bedeutung. Diese sind mit Stützflächen 74 versehen, die hinsichtlich Funktion und Wirkung den Stützflächen 67 der seitlichen Führungsorgane im Bereich der Packungsbahn 17 entsprechen. Die Stützflächen 74 sind vorliegend als radial außenliegende Begrenzung der Ausnehmungen 51 ausgebildet und so angeordnet, dass der Außenlappen 13 - Schachtel-Seitenlappen 71 und Deckel-Seitenlappen 72 - eine Abstützung auf der Stützfläche 74 finden, derart, dass der durch Pfeil 68 definierte Druck auf den Faltlappen 13 aufrechterhalten wird, und zwar bis zur Anlage desselben am Innenlappen 14. Die Stützfläche 74 ist mit einer zur Packung 10 abfallenden Schräge ausgebildet, sodass der Faltprozess für den Außenlappen 13 unter Aufrechterhaltung der Anlage der Lappenkante 62 an der Stützfläche 74 durchgeführt werden kann.A further special feature of the forming
Eine innovative Besonderheit besteht in der abgestimmten Steuerung der Bewegungen der Packungen 10 bis zur Übergabe an den Formrevolver 18. Die Bewegungsabläufe sind so eingerichtet, dass während eines Maschinentaktes die Packungen 10 von der Packungsbahn 17 an den Formrevolver 18 bzw. eine Tasche 19 übergeben wird. Besonders wichtig ist die Steuerung der Maschine dahingehend, dass das Aufbringen des Heißleims - Heißleimpunkte 31 -, der Vorschub entlang des Endbereichs der Packungsbahn 17, insbesondere durch den Schieber 41, und die Fertigfaltung der Packung 10, vorzugsweise im Bereich des Formrevolvers 18, während eines einzigen Maschinentakts erfolgen. Vorzugsweise wird zu diesem Zweck der Schieber 41 durch einen Servo angetrieben, kann also unabhängig von dem Vorschub der Packungen 10 im übrigen Bereich der Packungsbahn 17 wirken, insbesondere mit einer von der (kontinuierlichen) Bewegung der Packungen 10 im Bereich der Packungsbahn 17 abweichenden Bewegungscharakteristik. Die Eigenständigkeit der Förderbewegungen für die Packungen 10 ermöglicht das Aufbringen von Heißleim auch während reduzierter Maschinengeschwindigkeit und das Einführen der Packung 10 in den Formrevolver 18 bei erhöhter Fördergeschwindigkeit, sodass die Packung 10 kurzzeitig nach dem Aufbringen von Heißleim komplettiert wird. Optional kann demnach eine Kaltbeleimung entfallen. Der Antrieb des Schiebers 41 kann alternativ mit dem Maschinenantrieb gekoppelt sein. Wichtig ist die Einbettung der Beleimung mit Heißleim in einem Arbeitstakt, der stets bis zur Komplettierung der Packung, nämlich Herstellung der Leimverbindung, führt.An innovative special feature is the coordinated control of the movements of the
Der Schieber 41 erfasst die Packung vorzugsweise in einer Endphase des (kontinuierlichen) Transports durch den Gurt 22, sodass der Transport der Packungen 10 ohne Unterbrechung fortgesetzt wird, vorzugsweise mit einer erhöhten Fördergeschwindigkeit. Durch die gabelförmige Ausbildung des Mitnehmerkopfes 42 wird eine Kollision mit dem Gurt 22 ausgeschlossen. Der Schieber 41 transportiert die Packungen 10 in einem (fortlaufenden) Bewegungstakt durch die Beleimungsstation 27 bis in die Endstellung innerhalb des Formrevolvers 18.The
