Description

Die Erfindung betrifft eine Faltvorrichtung, insbesondere Faltrevolver, mit wenigstens einer einseitig abstehend positionierten Halterung - sogenannter Faltdorn - für die Herstellung einer im wesentlichen quaderförmigen Verpackung aus mindestens einem faltbaren Zuschnitt, insbesondere für Zigaretten, wobei der Faltdorn dünne Wandungen, nämlich großflächige Vorderwand und Rückwand sowie schmale Seitenwände, zur Anlage entsprechender Verpackungswandungen aufweist, und wobei Zuschnitteile einander im Bereich einer der schmalen Seitenwände überlappen und dort miteinander durch Klebung verbunden sind. Eine derartige Faltvorrichtung ist bekannt aus der DE 35 45 884 A.The invention relates to a folding device, in particular Folding turret, with at least one positioned on one side Bracket - so-called folding mandrel - for the production an essentially cuboid packaging from at least a foldable blank, especially for cigarettes, wherein the folding mandrel thin walls, namely large front wall and rear wall as well as narrow side walls, for the creation of appropriate Has packaging walls, and wherein cut parts each other overlap in the area of one of the narrow side walls and there are connected to each other by gluing. Such a folding device is known from DE 35 45 884 A.

Verpackungsmaschinen mit Faltdornen werden vor allem zur Herstellung von Zigaretten-Packungen, insbesondere Weichbecher-Packungen, eingesetzt. Bei diesen Packungen werden einander überlappende Zuschnitteile durch Klebung miteinander verbunden. Es hat sich herausgestellt, daß die die Überlappung aufweisende schmale Seitenwand der fertigen Verpackung breiter ist als die gegenüberliegende Seitenwand. Packaging machines with folding mandrels are mainly used for manufacturing of cigarette packs, especially soft cup packs, used. With these packs are each other overlapping cut parts connected by gluing. It has been found that the overlap narrow side wall of the finished packaging is wider than that opposite side wall.

Aufgabe der Erfindung ist es, Maßnahmen zur Erzielung eines möglichst genauen rechteckigen Querschnitts der Verpackung zu treffen.The object of the invention is to take measures to achieve a rectangular cross-section of the packaging as accurate as possible to meet.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Faltvorrichtung dadurch gekennzeichnet, daß die schmale Seitenwand zur Anlage der einander überlappenden Zuschnitteile eine geringere Breite als die gegenüberliegende schmale Seitenwand aufweist und somit der Faltdorn zur Erzielung eines nahezu rechteckigen Querschnitts der fertigen Verpackung selbst einen trapezförmigen Querschnitt aufweist.The folding device according to the invention is used to achieve this object characterized in that the narrow side wall to the system of the overlapping blank parts is less Has width than the opposite narrow side wall and thus the folding mandrel to achieve an almost rectangular Cross section of the finished packaging itself a trapezoidal Has cross section.

Der Erfindung liegt die Erkenntnis zugrunde, daß nach dem Verkleben der Faltlappen im Bereich der Seitenwand des Faltdorns die Relativlage der verklebten Faltlappen sich verändert. Um der sich daraus ergebenden Verbreiterung der Seitenwand entgegenzuwirken, ist der Faltdorn in diesem Bereich mit einer Seitenwand entsprechend geringerer Breite ausgebildet.The invention is based on the finding that after gluing the folding tab in the area of the side wall of the folding mandrel the relative position of the glued folding flap changes. Around counteract the resulting widening of the side wall, is the folding mandrel in this area with a side wall formed correspondingly smaller width.

Das Ausführungsbeispiel in den Zeichnungen befaßt sich mit der Fertigung von Zigaretten-Packungen des Typs Weichbecher. Ein Faltrevolver (nicht gezeigt), zum Beispiel in der Ausführung gemäß DE 35 45 884, weist eine Mehrzahl von längs des Außenumfangs des Faltrevolvers angeordneten Faltdornen 10 auf. Es handelt sich dabei um hohle, rohrförmige Organe, auf deren Außenumfang Zuschnitte der Packung gefaltet werden. Die Faltdorne 10 werden durch den Faltrevolver in Richtung von Pfeil 11 bewegt.The embodiment in the drawings deals with the Manufacture of soft-cup cigarette packs. On Folding turret (not shown), for example in the version according to DE 35 45 884, has a plurality of along the outer circumference of the folding turret arranged folding mandrels 10. It deals hollow, tubular organs on their outer circumference Blanks of the pack are folded. The folding mandrels 10 are moved in the direction of arrow 11 by the folding turret.

Die Faltdorne 10 sind am Faltrevolver so positioniert, daß eine großflächige Rückwand 12 radial nach außen gerichtet ist, und eine entsprechende Vorderwand 13 in Bezug auf die Radialrichtung des Faltrevolvers innen liegt. Eine schmale und in Drehrichtung vorn liegende Seitenwand 14 sowie eine in Drehrichtung zurückliegende schmale Seitenwand 15 sind annähernd radial gerichtet.The folding mandrels 10 are positioned on the folding turret so that a large rear wall 12 is directed radially outwards, and a corresponding front wall 13 with respect to the radial direction of the folding turret is inside. A narrow and in the direction of rotation front side wall 14 and one in the direction of rotation back narrow side wall 15 are directed approximately radially.

Die die Verpackung bildenden Zuschnitte werden nacheinander auf der Außenseite des Faltdorns 10 gefaltet (DE 196 41 151.3). Zuerst wird eine Innenumhüllung 16 - ein Stanniol-Zuschnitt - gefaltet und danach, außen auf dieser, eine äußere Umhüllung, nämlich ein Papier-Zuschnitt 17 für den sogenannten Weichbecher.The blanks forming the packaging are opened one after the other folded the outside of the folding mandrel 10 (DE 196 41 151.3). First an inner covering 16 - a tin foil blank - folded and then, on the outside, an outer wrapping, namely a paper blank 17 for the so-called soft cup.

Der Zuschnitt 17 für den Weichbecher wird in einer radial zum Faltrevolver gerichteten Position zwischen aufeinander folgenden Faltdornen 10 bereitgehalten und durch den in Förderrichtung nachfolgenden Faltdorn mitgenommen. Im Bereich erster radial außen und innen liegender, feststehender Faltorgane 18, 19 wird der Zuschnitt 17 des Weichbechers U-förmig um den Faltdorn 10 herumgefaltet, und zwar durch die Bewegung des Faltdorns 10 mit dem Zuschnitt relativ zu den feststehenden Faltorganen 18, 19.The blank 17 for the soft cup is in a radial to Folding turret facing position between successive Folding mandrels 10 held ready and in the direction of conveyance subsequent folding mandrel taken. Radially in the first area outside and inside, fixed folding members 18, 19 the blank 17 of the soft cup becomes U-shaped around the folding mandrel 10 folded around, namely by the movement of the folding mandrel 10 with the cut relative to the fixed folding members 18, 19th

Der Zuschnitt 17 für den Weichbecher ist so bemessen und wird so relativ zum Faltdorn 10 bereitgehalten, daß nach dem U-Falten auf der in Transportrichtung rückwärtigen Seite des Faltdorns, also im Bereich der schmalen Seitenwand 15, Faltlappen zur Bildung einer Seitenwand 22 des Weichbechers hinweg ragen. Es handelt sich im vorliegenden Fall um Seitenlappen, nämlich einen schmaleren Innenlappen 23 und einen breiteren Außenlappen 24. Der Innenlappen 23 liegt bei der fertiggefalteten Seitenwand 22 der Verpackung an der Innenseite und wird mindestens teilweise überdeckt durch den Außenlappen 24. The blank 17 for the soft cup is so dimensioned and is held so ready relative to the folding mandrel 10 that after the U-folding on the rear side of the folding mandrel in the direction of transport, thus in the area of the narrow side wall 15, folding tabs protrude to form a side wall 22 of the soft cup. In the present case, they are side tabs, namely a narrower inner lobe 23 and a wider outer lobe 24. The inner tab 23 lies on the fully folded side wall 22 of the packaging on the inside and will at least partially covered by the outer tab 24.

Innenlappen 23 und Außenlappen 24 sind bei der fertigen Verpackung durch Klebung miteinander verbunden. Diese wird durch Leimpunkte bewirkt, die auf einen der Seitenlappen aufgetragen sind, etwa auf die Außenseite des Innenlappens 23. Zur Herstellung der Seitenwand 22 wird nach dem Auftragen der Leimpunkte der Innenlappen 23 gegen die Außenseite der in Drehrichtung zurückliegenden Seitenwand 15 des Faltdorns 10 umgefaltet und sodann der Außenlappen 24 durch eine in Radialrichtung nach außen geführte Faltbewegung gegen den Innenlappen 23 gefaltet.Inner tabs 23 and outer tabs 24 are in the finished packaging bonded together by gluing. This is through Glue spots causes that applied to one of the side lobes are, for example on the outside of the inner lobe 23. For production the side wall 22 is after applying the glue spots the inner tab 23 against the outside of the back in the direction of rotation Side wall 15 of the folding mandrel 10 folded over and then the outer tab 24 by a radially outward guided folding movement folded against the inner tab 23.

Die teilweise gefalteten Weichbecher werden durch den Faltdorn 10 einer Faltstation 28 zugeführt. Im Bereich derselben wird der Innenlappen 23 gegen die Rückseite des Faltdorns 10 gefaltet, also gegen die zurückliegende Seitenwand 15 desselben.The partially folded soft cups are covered by the folding mandrel 10 fed to a folding station 28. In the same area the inner tab 23 is folded against the back of the folding mandrel 10, thus against the rear side wall 15 of the same.

Etwa zeitgleich wird der in Radialrichtung innen liegende Außenlappen 24 durch einen Falter 30 gegen die Rückseite des Faltdorns und damit gegen den unmittelbar vorher gefalteten Innenlappen 23 gefaltet.At about the same time, the one lying inside in the radial direction becomes Outer lobe 24 by a folder 30 against the back of the Folding mandrel and thus against the inner flap that was folded just before 23 folded.

Längs der Bewegungsbahn der Faltdorne 10 sind auf der in Radialrichtung äußeren und inneren Seite Führungsorgane vorgesehen, die überwiegend aus einer Mehrzahl von parallelen Rippen bzw. Stegen bestehen. So ist das radial innen liegende U-Faltorgan 19 in der Fortsetzung als radial innere Abstützung 44 ausgebildet. Ein innen liegender Schenkel 45 des U-förmig gefalteten Zuschnitts liegt an dieser Abstützung 44 an.Along the movement path of the folding mandrels 10 are in the radial direction outer and inner side guide organs provided, which predominantly consist of a plurality of parallel ribs or webs exist. So is the radially inner U-folding organ 19 continued as a radially inner support 44 educated. An inside leg 45 of the U-shaped folded The blank lies against this support 44.

Das obere bzw. radial außen liegende U-Faltorgan 18 ist entsprechend ausgebildet, erstreckt sich allerdings nur über einen kurzen Umfangsabschnitt des Faltrevolvers. Mit Abstand vom U-Faltorgan 18 folgt in Umfangsrichtung eine Außenführung 46. Im Bereich einer Lücke zwischen U-Faltorgan 18 und Außenführung 46 ist ein Leimaggregat 47 positioniert.The upper or radially outer U-folding member 18 is corresponding trained, but extends only over one short circumferential section of the folding turret. At a distance from the U-shaped folding organ 18 follows an outer guide 46 in the circumferential direction Area of a gap between the U-shaped folding member 18 and the outer guide 46 a glue unit 47 is positioned.

Nicht gezeigte Einzelheiten des Faltrevolvers können in geeigneter Weise ausgebildet sein, beispielsweise nach Maßgabe der DE 35 45 884. Des weiteren sind die beschriebenen Verfahrensschritte und Vorrichtungseinzelheiten auch für die Fertigung anderer Verpackungen geeignet, beispielsweise für die Fertigung von Verpackungen des Typs Klappschachtel aus dünnem Karton. Details of the folding turret, not shown, can be used in a suitable manner Be formed, for example in accordance with the DE 35 45 884. Furthermore, the described process steps and fixture details also for manufacturing other packaging suitable, for example for manufacturing of packaging of the type folding box made of thin cardboard.

Die Bildung der Seitenwand 22 durch Umfalten und Verleimung von Innenlappen 23 und Außenlappen 24 ist erst abgeschlossen, sobald der auf den Innenlappen 23 aufgebrachte Leim ausgehärtet ist. Während der hierfür erforderlichen Zeit ist die am Faltdorn 10 anliegende Außenumhüllung nicht dauernd abgestützt. Auch werden Innenlappen 23 und Außenlappen 24 nur kurzzeitig an die Seitenwand 15 des Faltdorns 10 angedrückt. Somit können sich noch Verschiebungen im Bereich der Leimverbindung ergeben. Tatsächlich weitet sich der Querschnitt der Außenumhüllung 10 in diesem Bereich etwas auf.The formation of the side wall 22 by folding and gluing Inner lobe 23 and outer lobe 24 is only completed as soon as the glue applied to the inner tab 23 cured is. During the time required for this is on the folding mandrel 10 adjacent outer sheathing is not permanently supported. Inner lobes 23 and outer lobes 24 are also only briefly on the side wall 15 of the folding mandrel 10 is pressed. So you can there are still shifts in the area of the glue connection. The cross section of the outer casing 10 actually widens something in this area.

Zur Kompensation dieses Effekts ist der Faltdorn 10 in besonderer Weise gestaltet. Dieser weist nämlich keinen exakt rechteckigen Querschnitt auf und ist statt dessen trapezförmig ausgebildet. Die in Transportrichtung zurückliegende Seitenwand 15, an der die durch Überlappung von Innenlappen 23 und Außenlappen 24 gebildete Seitenwand 22 zu liegen kommt, weist eine geringere Breite B15 als die Breite B14 der in Transportrichtung vorn liegenden Seitenwand 14 auf. Konkret beträgt die Breitendifferenz 1 mm bei einer Breite B15 = 20,6 mm und einer Breite B14 = 21,6 mm. Die Breite von Vorderwand 13 und Rückwand 12 beträgt etwa 54,3 mm.To compensate for this effect, the folding mandrel 10 is designed in a special way. This is because it does not have an exactly rectangular cross section and instead is trapezoidal. The side wall 15 lying back in the transport direction, on which the side wall 22 formed by overlapping of the inner flaps 23 and outer flaps 24 comes to rest, has a smaller width B 15 than the width B 14 of the side wall 14 lying forward in the transport direction. Specifically, the width difference is 1 mm with a width B 15 = 20.6 mm and a width B 14 = 21.6 mm. The width of the front wall 13 and rear wall 12 is approximately 54.3 mm.

Die sich ergebende Trapezform des Faltdornquerschnitts ist in besonderer Weise ausgerichtet. So liegen zwischen der radial innen liegenden Vorderwand 13 und Seitenwand 14 bzw. Seitenwand 15 jeweils rechte Winkel. Somit ist zwischen Rückwand 12 und in Transportrichtung vorn liegender Seitenwand 14 ein spitzer Winkel gebildet, während zwischen Rückwand 12 und in Transportrichtung zurückliegender Seitenwand 15 ein stumpfer Winkel gebildet ist.The resulting trapezoidal shape of the folding mandrel cross section is in aligned in a special way. So lie between the radial inner front wall 13 and side wall 14 or side wall 15 right angles each. Thus, between rear wall 12 and in Transport direction front side wall 14 an acute angle formed while between rear wall 12 and in the direction of transport back side wall 15 formed an obtuse angle is.

Aufgrund der weiter oben genannten unterschiedlichen Breiten B15 und B14 ergibt sich ein Winkel a zwischen vorn liegender Seitenwand 14 und außen liegender Rückwand 12 von 88,9°. Je nach Material und Leimverbindung kann der Winkel zwischen 88° und 89,5° variieren. Due to the different widths B 15 and B 14 mentioned above, there is an angle a between the front side wall 14 and the outer rear wall 12 of 88.9 °. Depending on the material and glue connection, the angle can vary between 88 ° and 89.5 °.

Die Breitendifferenz B14- B15 liegt bei 4% bis 6% (relativ zu B14) oder bei 1% bis 3% (relativ zur Breite von Vorderwand 13 oder Rückwand 12).The width difference B 14 - B 15 is 4% to 6% (relative to B 14 ) or 1% to 3% (relative to the width of front wall 13 or rear wall 12).

In diesem Zusammenhang ebenfalls von Bedeutung ist die Lage der Überlappung von Innenlappen 23 und Außenlappen 24. Innenlappen 23 ist gegenüber dem Außenlappen 24 kurz ausgebildet. Entsprechend liegt die Überlappung näher an der Rückwand 12 als an der Vorderwand 13. Auch die Innenumhüllung 16 weist eine Überlappung von Zuschnitteilen 50, 51 auf und zwar etwa mittig im Bereich der Rückwand 12. Die Klebestellen und Überlappungen sind somit im Bereich der durch spitze und stumpfe Winkel begrenzten, außen liegenden Rückwand 12 angeordnet und liegen damit von der Vorderwand 13 und den angrenzenden rechten Winkeln entfernt. So bleibt der optisch beste Eindruck für die Frontansicht der späteren fertigen Verpackung trotz eventueller Faltungen und Verschiebungen im Bereich von Leimstellen erhalten.The position of the Overlap of inner lobe 23 and outer lobe 24. Inner lobe 23 is short compared to the outer lobe 24. Corresponding the overlap is closer to the rear wall 12 than to the Front wall 13. The inner casing 16 also has an overlap of cut parts 50, 51 and approximately in the middle of the area the back wall 12. The glue spots and overlaps are thus in the area of the limited by acute and obtuse angles, outer rear wall 12 arranged and are thus from the front wall 13 and the adjacent right angles. This leaves the best visual impression for the front view the later finished packaging despite possible folds and get shifts in the area of glue spots.

Die Faltdorne 10 sind lediglich an einem Ende gelagert bzw. verankert und zwar an einer Tragscheibe 52 des Faltrevolvers. Der grundsätzliche Aufbau und die Lagerung des Faltdorns sind auch in der DE 44 37 404 beschrieben.The folding mandrels 10 are only supported at one end or anchored to a support plate 52 of the folding turret. The basic structure and storage of the folding mandrel are also described in DE 44 37 404.

Zur einseitigen Verankerung des Faltdorns 10 weist dieser an einem Ende 53 ein Verbindungsstück 54 auf, welches den Faltdorn 10 an seinem Ende 53 vollständig umgibt und mit dessen Ende 53 bündig abschließt (Fig. 3). Das Verbindungsstück 54 ist so ausgebildet, daß es in wirksamer Weise mit dem Faltrevolver bzw. der Tragscheibe 53 verbunden werden kann.For one-sided anchoring of the folding mandrel 10, this instructs an end 53 on a connector 54 which the folding mandrel 10 completely surrounds at its end 53 and with its end 53 ends flush (Fig. 3). The connecting piece 54 is designed that it is effective with the folding turret or the support plate 53 can be connected.

Das Ende 53 des Faltdorns 10 sitzt in einer Öffnung 55 des Verbindungsstücks 54. Dieses ist mit der Tragscheibe 53 des Faltrevolvers verbunden. Die Tragscheibe 52 ist zu diesem Zweck mit Durchbrüchen 56 versehen, in die jeweils ein Faltdorn 10 mit einem Verbindungsstück 54 als Einheit passend und formschlüssig einsetzbar ist. Der Durchbruch 56 ist im Querschnitt stufenförmig ausgebildet, mindestens im Bereich von zwei einander gegenüberliegenden Seiten. Es entsteht dadurch jeweils ein Versatz 57. In diesen tritt ein sich beidseitig erstreckender Flansch 58 des Verbindungsstücks 54 passend ein. Diese Art der Verbindung ist auch in der DE 44 37 404 beschrieben. The end 53 of the folding mandrel 10 sits in an opening 55 of the connecting piece 54. This is with the support plate 53 of the folding turret connected. The support plate 52 is for this purpose Breakthroughs 56 are provided, each with a folding mandrel 10 a connector 54 as a unit fit and form-fitting can be used. The opening 56 is step-shaped in cross section trained, at least in the range of two opposite one another Pages. This creates an offset 57. In this occurs a mutually extending Flange 58 of the connector 54 fits. That kind of Connection is also described in DE 44 37 404.

Das Verbindungsstück 54 weist auf der dem Faltdorn 10 abgewandten Seite einen Öffnungskragen 59 auf. Dieser nimmt das dem Faltrevolver bzw. der Tragscheibe 52 zugekehrte Ende des Faltdorns 10 auf. Das genannte Ende 53 dient der Einführung des Packungsinhalts, nämlich einer Zigaretten-Gruppe, in den Faltdorn 10 und ist trichterförmig ausgebildet. Hierzu sind im Bereich des Öffnungskragens 59 Rückwand 12, Vorderwand 13 und Seitenwände 14, 15 divergierend nach außen geformt. Zugleich schließt das Ende 53 bündig mit dem Öffnungskragen 59 ab. Der trapezförmige Querschnitt des Faltdorns 10 kann auch im Bereich des Endes 53 bzw. des Öffnungskragens 59 vorhanden sein.The connecting piece 54 points to the one facing away from the folding mandrel 10 Side an opening collar 59. This takes that from Folding turret or the end plate 52 facing the end of the folding mandrel 10 on. Said end 53 serves to introduce the Package contents, namely a group of cigarettes, in the folding mandrel 10 and is funnel-shaped. This is in the area of the opening collar 59 rear wall 12, front wall 13 and Sidewalls 14, 15 formed diverging outwards. At the same time closes the end 53 flush with the opening collar 59. The Trapezoidal cross section of the folding mandrel 10 can also be in the area of the end 53 or the opening collar 59 may be present.

Der Querschnitt des Faltdorns 10 (Ende 60) und der Querschnitt des Verbindungsstücks 54 sind derart aufeinander abgestimmt, daß zwischen beiden Teilen (entlang dem Verbindungsstück) ein Spalt 61 von 0,5 mm bis 2 mm Breite besteht. Die feste Verbindung beider Teile wird gewährleistet durch einen in diesen Spalt 61 eingebrachten Zwei-Komponenten-Kleber. The cross section of the folding mandrel 10 (end 60) and the cross section of the connecting piece 54 are coordinated with one another in such a way that between both parts (along the connector) Gap 61 of 0.5 mm to 2 mm in width. The firm connection both parts are guaranteed by one in them Gap 61 introduced two-component adhesive.
