Description

Die Erfindung betrifft eine Vorrichtung zum Einführen einer Bedruckstoffbahn gemäß dem Oberbegriff von Anspruch 1, ein Fertigungssystem zur Herstellung von Verpackungen gemäß Anspruch 7 und ein Verfahren zum Zuführen einer Bedruckstoffbahn gemäß Anspruch 8.The invention relates to a device for introducing a printing material web according to the preamble of claim 1, a production system for producing packaging according to claim 7 and a method for feeding a printing material web according to claim 8.

Stand der TechnikState of the art

Als Stanzen wird das Schneiden mit in sich geschlossenen geometrischen Zuschnittsformen bezeichnet, die kreisförmig, oval oder mehreckig sowie Fantasieformen aller Art sein können. Die Stanzung erfolgt gegen eine Stanzunterlage oder gegen einen Stempel, teilweise sind es auch Schervorgänge. Verpackungsmaterialien aus Kunststoff, Folienmaterial, Papier, Karton, Pappe oder Wellpappe werden hauptsächlich im Bogenformat, aber auch im Bahnformat gestanzt. Beim Stanzvorgang können zusätzlich aber auch Rilllinien oder Blindprägungen in den Nutzen eingebracht werden. Da es sich bei den Endprodukten um anspruchsvolle Verpackungen hinsichtlich technischer und graphischer Ausführung handelt, (Spezialverpackungen für Kosmetik, Zigaretten, Pharmazie, Lebensmittel etc.). werden besondere Anforderungen nicht nur an die Verpackungsmaterialien selbst gestellt, sondern es sind für optimale Resultate auch Stanzwerkzeuge mit geringsten Toleranzen und äußerst präzise und zuverlässig arbeitende Stanzmaschinen erforderlich. Diesen Ansprüchen wird das Flachbettstanzen am besten gerecht. Dabei werden im Falle der Bogenbearbeitung die bedruckten und auf einer Palette gestapelten Bogen der Stanzmaschine zugeführt. Im Falle der Bahnbearbeitung wird die Bedruckstoffbahn über Einführwalzen bzw. Zuführwalzen der Flachbettstanze zugeführt. Um die Bedruckstoffbahn im Stillstand bearbeiten zu können, wird die Bedruckstoffbahn in der Flachbettstanze iterativ angehalten, indem die nachfolgende Bahn in einem Bahnspeicher mit Tänzerrolle zwischengespeichert wird.Punching is defined as cutting with self-contained geometrical shapes, which can be circular, oval or polygonal as well as fantasy shapes of all kinds. The punching takes place against a punching pad or against a stamp, in some cases it is also shearing operations. Plastic packaging materials, film material, paper, cardboard, cardboard or corrugated board are mainly punched in sheet format but also in web format. When punching but also creasing lines or blind embossing can be introduced into the benefit. As the final products are sophisticated packaging in terms of technical and graphic design (special packaging for cosmetics, cigarettes, pharmaceuticals, food, etc.). special requirements are not only placed on the packaging materials themselves, but also punching tools with the smallest tolerances and extremely precise and reliable punching machines are required for optimum results. Flatbed punching best meets these demands. In this case, in the case of sheet processing, the printed sheets stacked on a pallet are fed to the punching machine. In the case of web processing, the printing material web is fed via infeed rollers or feed rollers to the flatbed punch. In order to be able to process the printing material web at standstill, the printing material web in the flatbed punch is iteratively stopped by temporarily storing the following web in a web store with a dancer roll.

In der EP 2 080 600 A1 wird ein Flachbettstanzmodul zum Stanzen eines Bedruckstoffes offenbart, mit einem Obertiegel und einem Untertiegel, wobei der Untertiegel mittels eines Antriebs relativ zum gestellfesten Obertiegel zur Ausführung eines Stanzhubes zum Stanzen des zwischen dem Obertiegel und dem Untertiegel passierenden Bedruckstoffs bewegbar ist. Dadurch wird der Untertiegel an den Obertiegel angestellt, und der Bedruckstoff mittels wenigstens eines Stanzwerkzeuges bearbeitet. Das Flachbettstanzmodul besitzt eine Bedruckstofftransporteinrichtung zur Führung des Bedruckstoffes, wobei diese am bewegbaren Untertiegel fest aufgenommen ist. Das Flachbettstanzmodul kann dabei in einer Flachbettstanze zur Bearbeitung einer Bedruckstoffbahn zum Einsatz gelangen und zu einem stabilen Bahnlauf beitragen.In the EP 2 080 600 A1 a flat bed punching module for punching a printing material is disclosed, with an upper crucible and a saucer, wherein the saucer by means of a drive relative to the frame-fixed upper crucible for performing a punching stroke for punching the passing between the upper crucible and the saucer printing substrate is movable. As a result, the saucer is employed on the upper crucible, and the printing material is processed by means of at least one punching tool. The flat bed stamping module has a printing material transport device for guiding the printing material, which is firmly held on the movable saucer. The flatbed punching module can be used in a flat bed punch for processing a printing material web and contribute to a stable web run.

Aus Kosten- und Umweltschutzgründen geht das Bestreben dahin, bei der Herstellung der oben genannten Verpackungsmaterialien in Druckmaschine und Flachbettstanzmaschine mit möglichst wenig Makulatur auszukommen.For cost and environmental reasons, the aim is to get along with the least possible waste in the production of the above-mentioned packaging materials in printing press and flatbed punching machine.

Um dem hohen Qualitätsanspruch gerecht zu werden, wird beim Anfahren von inline zueinander angeordneten Druckmaschinen und Flachbettstanzen das Bahnmaterial zuerst über einen Aufwickler oder per Handwicklung aus der Maschine gefahren, bevor das Bahnmaterial der Flachbettstanze zugeführt wird. Dies dient dazu, Wölbungen, die z. B. durch Leitrollen beim Stillstand der Druckmaschine entstehen können, vor Beginn des Stanzvorgangs in der Flachbettstanze zu entfernen, und dadurch Materialstaus beim Einlauf in die Flachbettstanze zu vermeiden. Nach diesem Vorgang muss ein Maschinenbediener bei Maschinen gemäßen dem Stand der Technik die Druckmaschine erneut stoppen, das Bahnmaterial stromaufwärtig des Aufwicklers durch einen Querschnitt abschneiden und nachfolgend manuell der Flachbettstanze zuführen. Durch das wiederholte Anhalten der Druckmaschine für das Zuführen der Materialbahn an die Flachbettstanze entsteht erneut Makulatur, so dass die ersten die Flachbettstanze verlassenden gestanzten Nutzen in der Regel noch nicht verwendet werden können.In order to meet the high quality standard, the web material is first driven by a rewinder or by hand winding from the machine when approaching inline to each other arranged printing machines and flat bed punches before the web material is fed to the flatbed punch. This serves to vaults, the z. B. may arise due to guide rollers at standstill of the printing machine to remove before the punching operation in the flatbed punch, and thereby avoid material jams when entering the flat bed punch. After this operation, a machine operator in prior art machines must stop the printing machine again, cut off the web material upstream of the rewinder by a cross section, and then manually feed the flatbed punch. The repeated stopping of the printing press for feeding the material web to the flatbed punch results in waste again, so that the first die cut punch leaving the flat bed punch usually can not yet be used.

Aufgabenstellungtask

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zum Einführen einer Bedruckstoffbahn zu schaffen und ein Verfahren zum Zuführen einer Bedruckstoffbahn zu beschreiben, welche die beim Anfahren einer Flachbettstanz- und / oder -prägemaschine bzw. eines Fertigungssytems mit einer Rollendruckmaschine und einer Flachbettstanz- und / oder -prägemaschine entstehende Makulatur deutlich reduzieren und deren Handhabung beim Hochfahren vereinfachen.The object of the present invention is therefore to provide a device for introducing a printing material web and to describe a method for feeding a printing material, which when starting a Flachbettstanz- and / or embossing machine or a Fertigungssytems with a web press and a Flachbettstanz- and / or embossing machine to significantly reduce waste and simplify their handling during startup.

Diese Aufgabe wird gelöst durch eine Vorrichtung zum Einführen einer Bedruckstoffbahn mit den Merkmalen von Anspruch 1. Die erfindungsgemäße Vorrichtung zum Einführen einer Bedruckstoffbahn, insbesondere aus Papier oder Karton, in einer Flachbettstanz- und / oder -prägemaschine hat einen Kompensator, der eine kontinuierliche Bahnbewegung der Bedruckstoffbahn in eine iterative Bahnbewegung wandelt. Erfindungsgemäß besitzt die Vorrichtung zum Einführen eine Klemmeinheit zum Klemmen der Bedruckstoffbahn und eine Schneideinheit zum Ausführen eines Querschnitts durch die Bedruckstoffbahn, wobei eine Querschnittkante entsteht, und besitzt weiterhin eine Einführeinheit zum Transport der Bedruckstoffbahn mit der Querschnittkante voraus in die Flachbettstanz- und / oder - prägemaschine. Die Vorrichtung erlaubt somit in vorteilhafter Weise ein automatisches Klemmen, Schneiden und Zuführen der Bedruckstoffbahn in die Flachbettstanz- und / oder -prägemaschine. Dadurch kann auf ein weiteres Stoppen der vorgelagerten Druckmaschine verzichtet werden und auch Makulatur reduziert werden. Ein weiterer Vorteil ergibt sich daraus, dass für das Zuführen der Bedruckstoffbahn kein Maschinenbediener bereitstehen muss und das Einführen der Bedruckstoffbahn in die Flachbettstanz- und / oder - prägemaschine beschleunigt werden kann.This object is achieved by a device for introducing a printing material web with the features of claim 1. The inventive device for introducing a printing substrate, in particular paper or cardboard, in a Flachbettstanz- and / or embossing machine has a compensator, the continuous web movement of the Converts substrate in an iterative trajectory movement. According to the invention, the device for insertion has a clamping unit for clamping the printing material web and a cutting unit for carrying out a cross section through the printing substrate, wherein a cross-sectional edge is formed, and further has an insertion unit for transporting the printing material with the cross-sectional edge ahead in the Flachbettstanz- and / or - embossing machine , The device thus advantageously permits automatic clamping, cutting and feeding of the printing material web into the flat-bed punching and / or embossing machine. This can be dispensed with a further stop the upstream printing machine and waste can be reduced. Another advantage results from the fact that no machine operator must be available for feeding the printing material web and the introduction of the printing material web can be accelerated in the Flachbettstanz- and / or - embossing machine.

In einer vorteilhaften Weiterbildung der erfindungsgemäßen Vorrichtung zum Einführen einer Bedruckstoffbahn besitzt die Einführeinheit eine Greifereinheit zum Greifen der Bedruckstoffbahn, mindestens eine Führungsbahn und einen der Greifereinheit zugeordneten Antrieb.

In einer besonders vorteilhaften und daher bevorzugten Weiterbildung sind die Klemmeinheit, die Schneideinheit und die Einführeinheit zwischen dem Kompensator und der Flachbettstanz- und / oder -prägemaschine angeordnet. Dadurch wird ermöglicht, dass der Querschnitt durch die Schneideinheit an einer stillstehenden Bedruckstoffbahn ausgeführt wird.In a particularly advantageous and therefore preferred development, the clamping unit, the cutting unit and the insertion unit between the compensator and the Flachbettstanz- and / or embossing machine are arranged. This makes it possible that the cross section is performed by the cutting unit on a stationary printing material.

In vorteilhafter Weiterbildung weist die Schneideinheit mindestens ein Messer und ein mit diesem mindestens einen Messer zusammenwirkendes Gegenelement auf, wobei sich das mindestens eine Messer und das Gegenelement über die Breite der Bedruckstoffbahn erstrecken.In an advantageous development, the cutting unit has at least one knife and a counter element interacting with this at least one knife, wherein the at least one knife and the counter element extend over the width of the printing material web.

Die Erfindung betrifft auch ein Fertigungssystem zur Herstellung von Verpackungen, insbesondere aus Papier oder Karton und insbesondere von Faltschachteln aus einer Bedruckstoffbahn, mit einer Rollendruckmaschine, mit einer stromabwärtig dazu angeordneten Vorrichtung zum Einführen nach einem der vorangehenden Ansprüche und mit einer weiter stromabwärtig dazu angeordneten Flachbettstanz- und / oder -prägemaschine.The invention also relates to a production system for the production of packaging, in particular of paper or cardboard and in particular of folding cartons from a printing material web, with a web-fed printing press, with a downstream arranged for insertion device according to one of the preceding claims and with a further downstream arranged Flachbettstanz- and / or embossing machine.

Die Erfindung betrifft auch ein Verfahren zum Zuführen einer Bedruckstoffbahn in einem Fertigungssystem zur Herstellung von Verpackungen, insbesondere wie oben stehend beschrieben von einer Rollendruckmaschine an einer Flachbettstanz- und / oder - prägemaschine mittels einer wie oben stehend beschriebenen Vorrichtung zum Einführen währen des laufenden Betriebs der Rollendruckmaschine. Dazu erfolgt in einem ersten Schritt ein Aufwickeln der Bedruckstoffbahn auf einen Hilfsaufwickler. In einem zweiten Schritt wird eine Ausgleichsbewegung eines Bahnleitelements für einen temporären Bahnstillstand erzeugt, beispielsweise durch einen Kompensator mit Tänzerwalze. Daraufhin wird die Bedruckstoffbahn mit einer Klemmeinheit geklemmt und es erfolgt ein Querschnitt durch die Bedruckstoffbahn, wobei eine Querschnittkante entsteht. In einem nachfolgenden Schritt erfolgt ein automatisches Einführen der Bedruckstoffbahn mit der Querschnittkante voraus in die Flachbettstanz- und / oder -prägemaschine.The invention also relates to a method for feeding a printing material web in a production system for producing packaging, in particular as described above from a web-fed printing press to a flatbed punching and / or embossing machine by means of a device for introducing during operation of the web-fed printing press as described above , This is done in a first Step on winding the printing material web onto an auxiliary winder.

Die Figur 1 zeigt eine schematische Ansicht einer erfindungsgemäßen Flachbettstanze 10, welche Teil eines Fertigungssystems 100 ist. Die gezeigte Ausführungsform der Flachbettstanze 10 mit einem Flachbettstanzmodul 12ist in horizontaler Bauweise modular aufgebaut. Die Bearbeitung einer Bedruckstoffbahn 24, beispielsweise von in einer vorangehenden Rollendruckmaschine 8 auf einer Kartonbahn gedruckte Faltschachteln erfolgt in dieser Darstellung von rechts nach links: Von einem Bahneinlaufteil 14 kommend gelangt die Bedruckstoffbahn 24 in Bahnlaufrichtung B in das Flachbettstanzmodul 12, in welchem die Bedruckstoffbahn 24 durch eine Hubbewegung H eines mit Stanzmessern bestückten Untertiegels 28 gegen einen Obertiegel 26 derart eingeschnitten wird, dass in nachfolgenden Bearbeitungsschritten zum Einen einzelne Bogen von der Bedruckstoffbahn 24 abtrennbar und zum Anderen einzelne Druckprodukte aus der Bedruckstoffbahn 24 herausgebrochen und voneinander trennbar sind. Die Trennung in einzelne Bogen erfolgt bereits am Auslauf des Flachbettstanzmoduls 12. Über eine im Flachbettstanzmodul 12 nachgeordnete Transporteinheit 16 gelangen die abgetrennten Bogen in einer Ausbrechereinheit 18 sowie eine Nutzentrenneinheit 20, in denen die Druckprodukte vom Beschnitt getrennt und vereinzelt werden. Die Druckprodukte werden sodann in einer Produktauslage 22 ausgelegt. Direkt stromaufwärtig des Flachbettstanzmoduls 12 ist eine erfindungsgemäße Einführungsvorrichtung 30 zum Einführen der Bedruckstoffbahn 24 in das Flachbettstanzmodul 12 angeordnet, welche anhand der Figur 2 näher beschrieben wird:The FIG. 1 shows a schematic view of a flat bed punch 10 according to the invention, which is part of a manufacturing system 100. The illustrated embodiment of the flatbed punch 10 with a flat bed punching module 12 is modular in horizontal construction. The processing of a printing substrate 24, for example, printed from a web-fed printing machine 8 on a board web folding cartons takes place in this illustration from right to left: Coming from a web inlet part 14 passes the printing substrate 24 in the web direction B in the flatbed punching module 12, in which the printing material 24 through a lifting movement H of an equipped with punching knobs saucer 28 is cut against a top bar 26 such that in subsequent processing steps for a single sheet separated from the printing material 24 and on the other individual printed products from the printing material 24 broken and separated from each other. The separation into individual sheets already takes place at the outlet of the flatbed punching module 12. The separated sheets are conveyed in a breakout unit 18 and a pay dividing unit 20 via a transport unit 16 arranged downstream in the flatbed punching module 12, in which the printed products are separated from the cut and separated. The printed products are then laid out in a product display 22. Directly upstream of the flat-bed punching module 12, an insertion device 30 according to the invention for inserting the printing material web 24 is arranged in the flat-bed stamping module 12, which is based on the FIG. 2 is described in more detail:

Die Bedruckstoffbahn 24 läuft von einer Rollendruckmaschine 8 kommend in Bahnlaufrichtung B über verschiedene Walzen, eine Zuggruppe 40 und einem als Bahnspeicher wirkenden Kompensator 31 in die Flachbettstanze 10. Wenn ein Bearbeitungsauftrag neu eingerichtet wird, oder wenn es zu Makulatur bedingenden Maschinenstopps in der vorgelagerten Rollendruckmaschine 8 kommt, so wird die Bedruckstoffbahn 24 nicht direkt in die Flachbettstanze 10 geführt, sondern zuvor auf einem Hilfsaufwickler 35 aufgewickelt. Sobald alle Makulatur aufweisenden Abschnitte der Bedruckstoffbahn 24 auf dem Hilfsaufwickler 35 aufgewickelt sind, kann die Bedruckstoffbahn 24 in die Flachbettstanze 10 eingeführt werden. Dies geschieht mit Hilfe der erfindungsgemäßen Einführvorrichtung 30. Dazu wird die Bedruckstoffbahn 24 in einer Klemmeinheit 32 geklemmt und somit definiert gehalten. Daraufhin kann eine Schneideinheit 33 einen Querschnitt als Trennschnitt durch die Bedruckstoffbahn 24 ausführen. Während der Hilfsaufwickler 35 das makulaturbehaftete Ende der Bedruckstoffbahn 24 weiter aufwickeln kann, wird die von der Rollendruckmaschine 8 kommende, makulaturfreie Bedruckstoffbahn 24 mit ihrer Querschnittkante voraus mittels einer Einführeinheit und deren Greifereinheit 34.1 in die Flachbettstanze 10 geführt. Die Greifereinheit 34:1 wird von einem Antrieb 34.3 auf einer Führungsbahn 34.2 in Bahnlaufrichtung B bewegt und übergibt die Bedruckstoffbahn 24 mit ihrer Querschnittkante voraus an Einführwalzen 36 der Flachbettstanze 10. Nach erfolgter Übergabe fährt die Greifereinheit 34.1 auf der Führungsbahn 34.2 wieder zurück in ihre Ausgangsposition, welche sich in unmittelbarer Nähe der Klemmeinheit 32 und der Schneideinheit 33 befindet, und wo die Übergabe der Bedruckstoffbahn 24 von der Klemmeinheit 32 an die Greifereinheit 34.1 der Einführeinheit 34 erfolgt.The printing substrate 24 runs from a web-fed printing machine 8 coming in web direction B on different rollers, a train group 40 and acting as a web memory compensator 31 in the flatbed 10. If a processing job is set up new, or if there is waste due to machine stops in the upstream web printing machine comes, the printing substrate 24 is not performed directly in the flatbed punch 10, but previously wound on an auxiliary winder 35. As soon as all waste paper-containing sections of the printing material web 24 are wound on the auxiliary winder 35, the printing material web 24 can be introduced into the flatbed punch 10. This is done with the aid of the insertion device 30 according to the invention. For this, the printing material web 24 in a clamping unit 32 clamped and thus kept defined. Thereupon, a cutting unit 33 can execute a cross section as a separating cut through the printing material web 24. While the auxiliary winder 35 can continue to wind up the wasteful end of the printing material web 24, the wastepaper web 24 coming from the web press 8 is guided with its cross-sectional edge ahead into the flatbed punch 10 by means of an insertion unit and its gripper unit 34.1. The gripper unit 34: 1 is moved by a drive 34.3 on a guideway 34.2 in the web running direction B and passes the printing material 24 with its cross-sectional edge ahead on insertion rollers 36 of the flatbed punch 10. After successful handover, the gripper unit 34.1 on the guideway 34.2 moves back to its original position , which is in the immediate vicinity of the clamping unit 32 and the cutting unit 33, and where the transfer of the printing substrate 24 from the clamping unit 32 to the gripper unit 34.1 of the insertion unit 34 takes place.

In Figur 3 ist eine alternative Ausführungsform der Einführvorrichtung 30 dargestellt. Während der gemäß in Figur 2 dargestellten Ausführungsform die Klemmeinheit 32 und die Schneideinheit 33 einerseits und die Greifereinheit 34.1 der Einführungseinheit 34 andererseits als separate Einheiten und Baugruppen ausgeführt sind, sind die Klemmeinheit 32 und die Greifereinheit 34.1 gemäß der Ausführungsform von Figur 3 als eine Baugruppe ausgeführt. Nach erfolgtem Trennschnitt durch die Schneideinheit 33 bleibt hier die Bedruckstoffbahn 24 durch die Klemmeinheit 32, welche gleichzeitig Greifereinheit 34.1 ist, geklemmt und wird von dieser Baugruppe durch den Antrieb 34.3 auf der Führungsbahn 34.2 in Bahnlaufrichtung B bewegt und der Flachbettstanze 10 zugeführt.In FIG. 3 an alternative embodiment of the introducer 30 is shown. While in accordance with in FIG. 2 1, the clamping unit 32 and the cutting unit 33 on the one hand and the gripper unit 34.1 of the insertion unit 34 on the other hand are designed as separate units and assemblies, the clamping unit 32 and the gripper unit 34.1 according to the embodiment of FIG FIG. 3 as an assembly. After the separation section has been cut by the cutting unit 33, the printing material web 24 remains clamped by the clamping unit 32, which is gripper unit 34.1 at the same time, and is moved by this assembly through the drive 34.3 on the guide track 34.2 in the web running direction B and fed to the flatbed punch 10.
