Description

Die Erfindung betrifft eine Vorrichtung zum Formen oder Vorformen von Zuschnitten für Packungen, insbesondere Klappschachteln mit abgerundeten oder polygonalen Längskanten, wobei die Zuschnite einer Formstation zuführbar sind mit wenigstens einem aus einer Formplatte mit formgebenden Längsrändern und bewegbaren Formwerkzeugen, insbesondere langgestreckten Formwalzen, bestehenden Formaggregat, wobei die bewegbaren Formwerkzeuge unter Verformung des Zuschnitts entlang Randbereichen der Formplatte bewegbar sind, insbesondere von der Unterseite der Formplatte zur Oberseite.The invention relates to a device for molding or preforming blanks for packs, in particular folding boxes with rounded or polygonal longitudinal edges, the blanks being able to be fed to a molding station with at least one molding unit consisting of a molding plate with shaping longitudinal edges and movable molding tools, in particular elongated molding rollers the movable molds can be moved along edge regions of the mold plate while deforming the blank, in particular from the underside of the mold plate to the top.

Klappschachteln - auch Hinge-Lid-Packung genannt - sind eine weitverbreitete Verpackungsform für Zigaretten. Neuerdings werden zunehmend Klappschachteln für Zigaretten eingesetzt, deren aufrechte Längskanten abgerundet, abgeschrägt oder polygonal ausgebildet sind. Die Fertigung derartiger Packungen erfordert eine Vorbehandlung der Zuschnitte, nämlich ein Vorformen derselben im Bereich der Längskanten. Ein Beispiel für eine Vorrichtung zum Formen bzw. Vorformen von Zuschnitten für Klappschachteln zeigt und beschreibt US 4 708 704.Folding boxes - also called hinge-lid packs - are a widely used form of packaging for cigarettes. Hinged boxes for cigarettes have recently been increasingly used, the upright longitudinal edges of which are rounded, beveled or polygonal. The manufacture of such packs requires pretreatment of the blanks, namely preforming them in the area of the longitudinal edges. US 4,708,704 shows and describes an example of a device for shaping or preforming blanks for hinged boxes.

Die vorliegende Erfindung befaßt sich mit einer Weiterentwicklung bzw. Verbesserung der Vorrichtung gemäß US 4 708 704 oder ähnlicher Formvorrichtungen für Zuschnitte.The present invention relates to a further development or improvement of the device according to US Pat. No. 4,708,704 or similar shaping devices for blanks.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, daß eine höhere Leistung beim Formen bzw. Vorformen der Zuschnitte erzielt wird.The invention has for its object to provide a device of the type mentioned in such a way that a higher performance is achieved when molding or preforming the blanks.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß die bewegbaren Formwerkzeuge, insbesondere Formwalzen, nach Ausführung eines formgebenden Bewegungstaktes von der Formplatte seitwärts abhebbar und entlang einer mit Abstand von der Formplatte verlaufenden Bewegungsbahn in die Ausgangsposition zurückführbar sind.To achieve this object, the device according to the invention is characterized in that the movable molds, in particular mold rollers, can be lifted sideways from the mold plate after execution of a shaping movement cycle and can be returned to the starting position along a movement path running at a distance from the mold plate.

Während beim Stand der Technik aufgrund US 4 708 704 die Formwerkzeuge, nämlich Formwalzen eine Auf- und Abbewegung im Bereich der seitlichen abgerundeten oder trapezförmigen Formränder der Formplatte durchführen, werden erfindungsgemäß die Formwerkzeuge nach Beendigung eines formgebenden Arbeitstaktes aus dem Bereich der Formplatte bewegt und mit deutlichem Abstand von dieser in die (untere) Ausgangsstellung zurückbewegt. Dadurch wird beträchtlich Zeit gewonnen. Wenn nämlich die Formwalzen in der oberen Position von der Formplatte abgehoben sind, kann der durch Vorformen bearbeitete Zuschnitt bereits abtransportiert und ein nachfolgender, unbearbeiteter Zuschnitt in Position gebracht werden. Wenn die Formwerkzeuge die Ausgangsstellung erreicht haben, kann der zu bearbeitende Zuschnitt die erforderliche Position an der Unterseite der Formplatte bereits erreicht haben. Der Vorteil liegt in einer wesentlich verkürzten Taktzeit der Formstation.While in the prior art, based on US Pat. No. 4,708,704, the shaping tools, namely shaping rollers, perform an up and down movement in the region of the lateral rounded or trapezoidal shaping edges of the shaping plate, according to the invention the shaping tools are moved out of the area of the shaping plate after completion of a shaping work cycle and with a clear Distance from this moved back to the (lower) starting position. This saves considerable time. If the form rollers are lifted off the mold plate in the upper position, the blank processed by preforming can already be transported away and a subsequent, unprocessed blank can be brought into position. When the molding tools have reached the starting position, the blank to be machined can already have reached the required position on the underside of the molding plate. The advantage is a significantly reduced cycle time of the forming station.

Zur Betätigung der Formwalzen ist erfindungsgemäß ein mechanisches Getriebe vorgesehen, das aus einem schwenkbar sowie auf- und abbewegbar gelagerten Winkelhebel für die Formwalzen und zwei in aufeinander abgestimmter Weise wirkenden Betätigungsgetrieben besteht. Hierdurch ergeben sich unterschiedliche Bewegungsbahnen der Formwerkzeuge während des vorzugsweise von unten nach oben verlaufenden Arbeitstaktes einerseits und während der Rückkehr in die Ausgangsstellung andererseits.According to the invention, a mechanical gear is provided for actuating the shaping rollers, said gear mechanism being pivotable and opening and closing there is movably mounted angle lever for the forming rollers and two actuating gears acting in a coordinated manner. This results in different trajectories of movement of the molding tools during the working cycle, which preferably runs from bottom to top, on the one hand and during the return to the starting position on the other hand.

Das in den Zeichnungen dargestellte Ausführungsbeispiel befaßt sich mit der Herstellung von Klappschachteln 10, deren vordere und/oder rückseitige, aufrechte Längskanten 11, 12 abgerundet sind. Es entsteht so eine Klappschachtel in der Gestaltung gemäß US 4 753 383.The embodiment shown in the drawings is concerned with the production of hinged boxes 10, the front and / or rear, upright longitudinal edges 11, 12 are rounded. A folding box is thus created in the design according to US 4,753,383.

Zur Herstellung derartiger Klappschachteln 10 werden einem üblichen Zuschnitt-Magazin 13 nacheinander ungefaltete Zuschnitte 14 an der Unterseite entnommen. Bei dem vorliegenden Ausführungsbeispiel ist hierfür ein in der Praxis üblicher Abroller 15 tätig.In order to produce such folding boxes 10, unfolded blanks 14 on the underside are taken from a customary blank magazine 13 one after the other. In the present exemplary embodiment, a dispenser 15 which is customary in practice is used for this.

Die Zuschnitte 14 gelangen nach dem Verlassen des Zuschnitt-Magazins 13 in eine Zuschnittbahn 16. Diese führt zu einem Faltrevolver 17, in dessen Bereich die Klappschachteln 10 weitgehend fertiggestellt und gefüllt werden. Der Faltrevolver 17 kann in der in US 4 084 393 beschriebenen Weise ausgebildet sein.After leaving the blank magazine 13, the blanks 14 arrive in a blank path 16. This leads to a folding turret 17, in the area of which the hinged boxes 10 are largely completed and filled. The folding turret 17 can be designed in the manner described in US Pat. No. 4,084,393.

Dem Faltrevolver 17 ist im Bereich der Zuschnittbahn 16 eine Formstation 18 vorgeordnet. In deren Bereich werden die Längskanten 11, 12 im Bereich des im übrigen flachen, ungefalteten Zuschnitts im Sinne einer Abrundung vorgeformt. Der vorgeformte Zuschnitt wird danach auf der Zuschnittbahn 16 dem Faltrevolver 17 zugeführt und in üblicher Weise weiterverarbeitet.A forming station 18 is arranged upstream of the folding turret 17 in the region of the cutting path 16. In the area of the longitudinal edges 11, 12 are preformed in the area of the otherwise flat, unfolded blank in the sense of a rounding. The preformed blank is then fed to the folding turret 17 on the blank web 16 and processed in a conventional manner.

Die Formstation 18 ist mit mindestens einem Formaggregat 19 ausgestattet. Dieses besteht aus einem feststehenden Formwerkzeug, nämlich einer Formplatte 20 und zwei bewegbaren Formwerkzeugen, nämlich Formwalzen 21 und 22. Die Formplatte 20 ist mit seitlichen, in Längsrichtung verlaufenden Formrändern 23, 24 ausgebildet, die der Kontur der herzustellenden Längskante 11, 12 entsprechen. Im vorliegenden Falle sind demnach die Formränder 23, 24 rund. Die Formplatte 20 ist an die Abmessungen des Zuschnitts 14 angepaßt. Seitliche Bereiche desselben ragen in der Ausgangsstellung seitlich über die Formplatte 20 hinweg. Es handelt sich dabei um die bei einem Zuschnitt 14 für Klappschachteln 10 üblichen Seitenlappen 25, 26. Diese werden bei der Vorformung des Zuschnitts gegen die Formränder 23, 24 gedrückt, so daß im Bereich zwischen den Seitenlappen 25 und 26 einerseits und einem mittleren Bereich des Zuschnitts 14 die abgerundeten Längskanten 11 geformt werden.The molding station 18 is equipped with at least one molding unit 19. This consists of a fixed mold, namely a mold plate 20 and two movable molds, namely mold rollers 21 and 22. The mold plate 20 is formed with lateral, longitudinally extending mold edges 23, 24 which correspond to the contour of the longitudinal edge 11, 12 to be produced. In the present case, the shape edges 23, 24 are therefore round. The molding plate 20 is adapted to the dimensions of the blank 14. Lateral areas of the same protrude laterally beyond the mold plate 20 in the starting position. These are the side flaps 25, 26 which are customary in a blank 14 for folding boxes 10. These are pressed against the mold edges 23, 24 during the preforming of the blank, so that in the region between the side flaps 25 and 26 on the one hand and a central region of the Blank 14, the rounded longitudinal edges 11 are formed.

Bei dem vorliegenden Ausführungsbeispiel wird der Zuschnitt 14 auf der Zuschnittbahn 16 durch Transportwalzen 27 in die Formstation 18 gefördert, und zwar derart, daß der Zuschnitt 14 unterhalb der Formplatte 20 liegt. Durch geeignete Halteorgane, insbesondere Saugorgane (nicht dargestellt) wird der Zuschnitt gegen die Unterseite der Formplatte 20 gedrückt. Der Zuschnitt 14 nimmt dabei die in Fig. 2 und Fig. 3 gezeigte Position ein.In the present exemplary embodiment, the blank 14 is conveyed on the blank web 16 by transport rollers 27 into the molding station 18, specifically in such a way that the blank 14 lies below the molding plate 20. The blank is pressed against the underside of the molding plate 20 by suitable holding members, in particular suction members (not shown). The blank 14 assumes the position shown in FIGS. 2 and 3.

Um eine exakte Führung und Positionierung des Zuschnitts 14 bei Übergabe an die Formplatte 20 zu gewährleisten, sind der Formplatte 20 Förderscheiben 43 zugeordnet. Diese sind im vorliegenden Fall an der Formplatte 20 selbst angeordnet. Die Förderscheibe 43 tritt mit einem unteren Bereich in einen Längsschlitz 44 am Ende der Formplatte 20 ein. Die Förderscheibe 43 wirkt mit einer zusätzlichen, unterhalb der Formplatte 20 angeordneten Förderscheibe (nicht gezeigt) zusammen. Eine der Förderscheiben 43 ist in enger Nachbarschaft zu den Transportwalzen 27 angeordnet. So ist für die Übergabe des Zuschnitts 14 an die Formplatte 20 eine Führung durch mehrere Organe gegeben.In order to ensure exact guidance and positioning of the blank 14 upon transfer to the mold plate 20, 20 conveyor disks 43 are assigned to the mold plate. In the present case, these are arranged on the molding plate 20 itself. The conveyor disk 43 enters with a lower region into a longitudinal slot 44 at the end of the molding plate 20. The conveyor disc 43 acts with an additional, arranged below the mold plate 20 Conveyor disc (not shown) together. One of the conveyor disks 43 is arranged in close proximity to the transport rollers 27. Thus, a guide through several organs is provided for the transfer of the blank 14 to the mold plate 20.

Nunmehr werden die Formwalzen 21, 22 wirksam. Diese befinden sich in einer Ausgangsstellung unterhalb der Formplatte 20 und auch unterhalb des Zuschnitts 14. Die Formwalzen 21, 22 werden nun entlang einer ersten kreisförmigen Bewegungsbahn 28 entlang der Kontur der Formränder 23 unter Mitnahme der überstehenden Teile des Zuschnitts 14 bis in eine obere, in Fig. 3 strichpunktierte Position bewegt. Dabei werden die Bereiche der Längskanten 11, 12 unter Druck an die Formränder 23, 24 angelegt.Now the form rollers 21, 22 are effective. These are in a starting position below the molding plate 20 and also below the blank 14. The molding rollers 21, 22 are now along a first circular movement path 28 along the contour of the molding edges 23, taking the protruding parts of the blank 14 into an upper, in Fig. 3 dash-dotted position moves. The areas of the longitudinal edges 11, 12 are placed under pressure on the mold edges 23, 24.

Nach diesem formgebenden Arbeitstakt kehren die Formwalzen 21, 22 in die Ausgangsstellung zurück, nämlich unterhalb der Formplatte 20. Dabei werden die Formplatten entlang einer Bewegungsbahn 29 bewegt. Diese ist so gewählt, daß die Formwalzen 21, 22 aus der oberen Endstellung seitwärts und sodann abwärts und schließlich zurück in die Ausgangsstellung gelangen. Die Seitwärtsbewegung der Formwalzen 21, 22 bewirkt, daß sie vollständig aus dem Bereich der Formplatte 20 bzw. des Zuschnitts 14 gelangen. Unmittelbar nach Beendigung des formgebenden Arbeitstaktes kann demnach der verformte Zuschnitt 14 abtransportiert und ein neuer, ebener Zuschnitt 14 zugeführt werden. Dieser kann sich bereits in der Arbeitsstellung gemäß Fig. 2 befinden, wenn die Formwalzen 21, 22 die Ausgangsstellung (ausgezogene Linien in Fig. 3) erreichen.After this shaping work cycle, the shaping rollers 21, 22 return to the starting position, namely below the shaping plate 20. The shaping plates are moved along a movement path 29. This is chosen so that the forming rollers 21, 22 move sideways from the upper end position and then downwards and finally back to the starting position. The sideways movement of the shaping rollers 21, 22 causes them to come completely out of the area of the shaping plate 20 or of the blank 14. Immediately after the shaping work cycle has ended, the deformed blank 14 can be removed and a new, flat blank 14 can be fed. This can already be in the working position according to FIG. 2 when the forming rolls 21, 22 reach the starting position (solid lines in FIG. 3).

Die Bewegung der Formwalzen 21, 22 entlang der unterschiedlich gestalteten Bewegungsbahnen 28, 29 wird durch ein besonderes Getriebe erreicht. Gemäß Ausführungsbeispiel der Fig. 3 sind die Formwalzen 21, 22 an oberen Enden eines Winkelhebels 30 angeordnet. Die Formwalzen 21, 22 sind am oberen, freien Ende eines aufrechten Schenkels 31 angeordnet. Auf einen in Ausgangsstellung horizontal gerichteten Schenkel 32 wirkt ein Hubantrieb 33. Dieser besteht im vorliegenden Falle aus einem im wesentlichen auf- und abbewegbaren Lenker 34, der gelenkig mit dem freien Ende des Schenkels 32 einerseits und mit einem Betätigungshebel 35 andererseits verbunden ist. Letzterer wird in vertikaler Ebene in schwenkendem Sinne auf- und abbewegt.The movement of the forming rollers 21, 22 along the differently designed movement paths 28, 29 is achieved by a special gear. According to the exemplary embodiment in FIG. 3, the shaping rollers 21, 22 are arranged at the upper ends of an angle lever 30. The shaping rollers 21, 22 are arranged at the upper, free end of an upright leg 31. A lifting drive 33 acts on a leg 32 which is oriented horizontally in the starting position. In the present case, this consists of a link 34 which can be moved up and down and which is articulated the free end of the leg 32 on the one hand and with an actuating lever 35 on the other hand. The latter is moved up and down in the vertical plane in a pivoting sense.

Die komplexe, überlagerte Bewegung der Formwalzen 21, 22 entlang den Bewegungsbahnen 28, 29 wird durch die Arbeitsweise eines weiteren Getriebes bewirkt. Dieses ist hier als Kurbel 36 ausgebildet mit einem Kurbelarm 37. Die Kurbel 36 liegt in der Darstellung gemäß Fig. 3 verdeckt hinter dem Winkelhebel 30. Dieser ist im Bereich eines Drehlagers 38 mit dem Kurbelarm 37 verbunden, wobei das Drehlager 38 im Bereich der Verbindung der beiden Schenkel 31, 32 liegt. Ein ortsfestes Kurbellager 39 liegt darüber.The complex, superimposed movement of the forming rollers 21, 22 along the movement paths 28, 29 is brought about by the operation of another gear. This is designed here as a crank 36 with a crank arm 37. In the illustration according to FIG. 3, the crank 36 is concealed behind the angle lever 30. This is connected to the crank arm 37 in the region of a pivot bearing 38, the pivot bearing 38 being in the region of the connection of the two legs 31, 32. A stationary crank bearing 39 lies above it.

Das durch die Kurbel 36 gebildete Getriebe ist vor allem für die Seitwärtsbewegungen der Formwalzen 21, 22 verantwortlich. Diese Bewegung wird überlagert mit der Aufwärtsbewegung des Lenkers 34. Der Kurbelarm 37 führt eine hin- und hergehende Bewegung in vertikaler Ebene aus, die durch einen Bewegungspfeil 40 gekennzeichnet ist. Die Verbindungsstelle zwischen Lenker 34 und Schenkel 32, nämlich ein Drehlager 41, bewegt sich dabei entlang einer komplexen Bewegungsbahn 42, die annähernd die Form einer "8" hat.The transmission formed by the crank 36 is primarily responsible for the sideways movements of the forming rolls 21, 22. This movement is superimposed on the upward movement of the link 34. The crank arm 37 executes a reciprocating movement in the vertical plane, which is indicated by an arrow 40. The connection point between the handlebar 34 and the leg 32, namely a pivot bearing 41, moves along a complex movement path 42 which has approximately the shape of an "8".

Weitere konstruktive Einzelheiten der Formstation 18 können entsprechend US 4 708 704 ausgebildet sein. Dies gilt insbesondere für Förderorgane zum Abtransport der Zuschnitte. Die Bewegung der Formwerkzeuge, nämlich Formwalzen 21, 22 kann auch in gegengesetzter Richtung ablaufen.
