Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Durchbrechen von Stegen, die entlang einer Schnittlinie die benachbarten Kanten eines Faltschachtelzuschnitts zusammenhalten, gemäß dem Oberbegriff von Anspruch 1.The present invention relates to a device for breaking webs, which hold along a cutting line the adjacent edges of a folding box blank, according to the preamble of claim 1.

Faltschachteln sind raumbildende Packmittel, die aus ebenen Zuschnitten geformt werden. Da sie in ihrer überwiegenden Gebrauchsform, dem Quader, sehr gut zu stapeln, zu lagern und zu transportieren sind, sind sie das verbreitetste Packmittel in der Industrie, im Handel und für den individuellen Gebrauch. Dem entsprechend ist die Erscheinungsform von Schachteln besonders vielfältig.Folding cartons are space-forming packaging materials that are formed from flat blanks. Since they are very easy to stack, store and transport in their predominant form of use, the cuboid, they are the most widely used packaging material in the industry, in commerce and for individual use. Accordingly, the appearance of boxes is particularly diverse.

Für einige Faltschachtelzuschnitte ist es vorteilhaft und teilweise sogar notwendig, während des Stanzvorganges kleine Verbindungsstege entlang der Schnittlinie benachbarter Kanten übrig zu lassen. Diese Verbindungsstege, meist in Form von punktförmigen Verbindungen, sollen die benachbarten Kanten zusammenhalten und insbesondere verhindern, dass die Zuschnitte aneinander hängen bleiben. Die Stege sind entlang der Schnittlinie voneinander beabstandet angeordnet.For some folding carton blanks, it is advantageous and sometimes even necessary to leave small connecting webs along the cutting line of adjacent edges during the stamping process. These connecting webs, usually in the form of punctiform connections, are intended to hold the adjacent edges together and, in particular, to prevent the blanks from sticking to one another. The webs are spaced apart along the cutting line.

Beim Verarbeiten derartiger Faltschachtelzuschnitte in einer Faltschachtelklebemaschine ist es notwendig, dass die Verbindungsstege vor der Durchführung der Falt- und Klebevorgänge der Zuschnitte getrennt werden. Hierzu ist es aus der EP 1 138 454 B1 bekannt, die Stege mit Scherwerkzeugen, die sich auf parallelen Wellen befinden, abzuscheren. Aus diesem Dokument sind die Merkmale des Oberbegriffs des Anspruchs 1 bekannt.When processing such carton blanks in a folder gluer, it is necessary that the connecting webs be separated prior to performing the folding and gluing operations of the blanks. For this it is from the EP 1 138 454 B1 known to shear the webs with shearing tools, which are located on parallel shafts. From this document, the features of the preamble of claim 1 are known.

Für Flachbettstanzen ist es weiterhin aus der EP 0 942 813 B1 bekannt, zum Ausbrechen und Entfernen von Abfallstanzteilen, die ebenfalls mit Haltepunkten entlang der Schnittkante versehen sind, ein Ausbrechbrett zur Aufnahme des Zuschnitts vorzusehen sowie eine obere und / oder untere Ausbrechform, wobei die Ausbrechform mit Ausbrechwerkzeugen zum Ausbrechbrett hin vertikal bewegbar ist.For flat bed stamping it is still from the EP 0 942 813 B1 Known for breaking out and removal of waste stampings, which are also provided with breakpoints along the cutting edge to provide a breakout board for receiving the blank and an upper and / or lower Ausbrechform, the breakout form is vertically movable with Ausbrechwerkzeugen the breakout.

Es ist Aufgabe der vorliegenden Erfindung eine kostengünstige, alternative Vorrichtung zum Durchbrechen von Stegen an benachbarten Kanten von Faltschachtelzuschnitten zu schaffen, mit der ein zuverlässiges Durchbrechen der Stege auch bei hohen Verarbeitungsgeschwindigkeiten gewährleistet ist, und die leicht auf unterschiedliche Faltschachtelformate eingestellt werden kann.It is an object of the present invention to provide an inexpensive, alternative device for breaking webs on adjacent edges of folding box blanks, with the reliable breakthrough of the webs is ensured even at high processing speeds, and can be easily adjusted to different carton formats.

Gelöst wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des kennzeichnenden Teils von Anspruch 1.This object is achieved by a device having the features of the characterizing part of claim 1.

In einer bevorzugten Ausführungsform besteht die Vorrichtung aus einer Vierkantprofilwelle mit Werkzeugaufnahmeelementen. Hierbei können die Werkzeugaufnahmeelemente aus Gewindeschrauben bestehen, deren Gewindeschaft länger ist als der Querschnitt der Vierkantprofilwelle. Die Werkzeugaufnahmeelemente sind dabei in einer Langlochdurchgangsbohrung durch die Vierkantprofilwelle angeordnet. Hierdurch ist es möglich, mit einfachen genormten maschinenbaulichen Elementen eine flexible Vorrichtung zu schaffen, die einfach auf unterschiedliche Steganordnungen unterschiedlicher Faltschachtelzuschnitte eingestellt werden kann. Durch die Langlochbohrung wird eine axiale Verschiebung der Werkzeuge extrem vereinfacht. Die notwendigen Ausbrechwerkzeuge können dann mit ihrer Innenbohrung leicht auf die Werkzeugaufnahmeelemente aufgeschraubt werden. Auch hierdurch ist es möglich, flexibel auf unterschiedliche Anforderungen des zu bearbeitenden Materials zu reagieren, da die Ausbrechwerkzeuge leicht montierbar und austauschbar sind.In a preferred embodiment, the device consists of a square profile shaft with tool receiving elements. Here, the tool receiving elements may consist of threaded screws whose threaded shaft is longer than the cross section of the square profile shaft. The tool receiving elements are arranged in a slot through hole through the square profile shaft. This makes it possible to create a flexible device with simple standardized mechanical engineering elements, which can be easily adjusted to different web arrangements of different folding carton blanks. Through the long hole drilling an axial displacement of the tools is extremely simplified. The necessary stripping tools can then be easily screwed with their inner bore on the tool holder elements. This also makes it possible to react flexibly to different requirements of the material to be processed, since the stripping tools are easy to assemble and replace.

In einer weiteren vorteilhaften Ausgestaltung ist die Vierkantprofilwelle mit einem eigenen Antrieb, vorzugsweise einem Servomotor, versehen. Hierdurch wird es ermöglicht, dass die Vierkantprofilwelle eine von der Transportbewegung der Faltschachtel unabhängige Rotationsbewegung ausführen kann.In a further advantageous embodiment, the square profile shaft is provided with its own drive, preferably a servomotor. This makes it possible that the square profile shaft can perform an independent of the transport movement of the carton rotational movement.

In einer weiteren bevorzugten Ausführungsform ist in der ebenen Bahn zur Beförderung der Faltschachtelzuschnitte zumindest im Bereich der Durchbrechvorrichtung ein federndes Stützblech angeordnet. Hierdurch entsteht ein federndes Widerlager, welches einerseits ein Aufbrechen der Stege ermöglicht und andererseits die notwendige Stütze für die Faltschachtel bietet.In a further preferred embodiment, a resilient support plate is arranged in the planar path for conveying the folding box blanks at least in the area of the perforating device. This creates a resilient abutment, which on the one hand allows breaking the webs and on the other hand provides the necessary support for the carton.

Der prinzipielle Aufbau einer Faltschachtelklebemaschine ist in Fig. 1 dargestellt. In Förderrichtung (in Fig. 1 von links nach rechts) beginnt die Faltschachtelmaschine mit einem Einleger 1, der die zu verarbeitenden Zuschnitte mit hoher Geschwindigkeit aus einem Stapel nacheinander abzieht und einzeln der nachfolgenden Bearbeitungsstation zuführt. Auf den Einleger 1 folgen als nächste Bearbeitungsstationen zwei Vorbrecher 2, 3, die Faltelemente enthalten, um Faltlappen vor und zurück zu falten. Durch das Knicken um 180° werden die entsprechenden Linksrilllinien der Zuschnitte weich und geschmeidig gemacht.The basic structure of a folding box gluer is in Fig. 1 shown. In conveying direction (in Fig. 1 from left to right), the folding carton machine starts with a feeder 1, which pulls the blanks to be processed at high speed from a stack one after the other and feeds them individually to the subsequent processing station. On the insert 1 follow as the next processing stations two primary crushers 2, 3, the folding elements included to fold folding flaps back and forth. By bending by 180 °, the corresponding left-ridge lines of the blanks are made soft and supple.

Auf den Vorbrecher 3 folgt als nächste Bearbeitungsstation die Faltstation 4, an deren Anfang ein Auftragwerk 5 für Klebstoff, üblicherweise Leim, angeordnet ist. Das Klebstoffauftragwerk 5 enthält Leimdüsen oder Leimscheiben, von denen der Klebstoff streifenförmig auf die Zuschnitte aufgebracht wird. Anschließend werden die Faltlappen der Zuschnitte von Faltelementen gefaltet.On the primary crusher 3 follows as the next processing station, the folding station 4, at the beginning of an applicator 5 for adhesive, usually glue, is arranged. The adhesive applicator 5 contains glue nozzles or glue discs, of which the adhesive is applied in strips on the blanks. Subsequently, the folding flaps of the blanks of folding elements are folded.

Als nächste Station folgt eine Überleitstation 6, in der die gefalteten, mit noch nicht abgebundenen Klebenähten versehenen Zuschnitte in allen Teilen exakt ausgerichtet einer nachfolgenden Sammel- und Presseinrichtung 7 zugeführt werden. Im Bereich der Überleitstation 6 können Einrichtungen angeordnet werden, mit denen die Schachteln gezählt, markiert und - falls schadhaft - ausgeschleust werden. In der Sammel- und Presseinrichtung 7 wird zunächst ein Schuppenstrom aus gefalteten Zuschnitten gebildet, der anschließend zwischen Pressbändern für einige Zeit unter Druck gehalten wird, damit die Klebenähte abbinden. Zum Abschluss ist häufig eine Packeinrichtung (nicht dargestellt) angeordnet, in der die flachliegend gefalteten Faltschachteln in Umkartons gepackt werden.The next station is followed by a transfer station 6, in which the folded blanks provided with not yet set adhesive seams are exactly aligned in all parts with a subsequent collecting and pressing device 7. In the area of the transfer station 6 facilities can be arranged with which the boxes are counted, marked and - if defective - are discharged. In the collecting and pressing device 7, a shingled stream of folded blanks is first formed, which is then held under pressure for some time between press belts, so that the adhesive seams set. Finally, a packing device (not shown) is often arranged, in which the flat-folded cartons are packed in outer cartons.

Falls zur Herstellung bestimmter Schachtelformen erforderlich, enthält die Faltschachtelklebemaschine weitere Bearbeitungsstationen, beispielsweise zusätzliche Faltstationen zur Durchführung weiterer Faltungen oder eine Drehstation zum Drehen der Zuschnitte um eine zur Transportebene senkrechte Drehachse, damit abgewinkelt zur Transportrichtung verlaufende Faltlinien vor dem Falten in eine Richtung parallel zur Transportrichtung gedreht werden.If required for the production of certain box shapes, the folding box gluing machine contains further processing stations, for example additional folding stations for carrying out further folding or a turning station for rotating the blanks about a rotation axis perpendicular to the transport plane, so that angled folding lines running in the direction of transport are rotated in one direction parallel to the transport direction before being folded become.

Bei der Verarbeitung von Schachtelzuschnitten mit Verbindungsstegen wird zwischen Einleger 1 und Vorbrecher 2 eine Vorrichtung 11 zum Durchbrechen von Stegen eingebaut. Jede der Bearbeitungsstationen (Einleger 1, Vorbrecher 2, 3, Faltstation 4, Überleitstation 6 und Sammel- und Presseinrichtung 7, sowie ggf. weitere Faltstationen oder eine Drehstation) weist eigene angetriebene Fördermittel auf, um die Zuschnitte im Durchlauf durchzufördern. Die Bearbeitungsstationen zwischen dem Einleger 1 und der Sammel- und Presseinrichtung 7, also die Vorbrecher 2, 3, die Faltstation 4 und die Überleitstation 6, enthalten als Fördermittel zwei oder drei sich parallel mit Abstand voneinander in Förderrichtung erstreckende Riemenpaare, die jeweils aus einem unteren Riemen 8 und einem oberen Riemen bestehen, zwischen denen die Zuschnitte gehalten und transportiert werden.When processing box blanks with connecting webs, a device 11 for breaking webs is installed between insert 1 and primary crusher 2. Each of the processing stations (feeder 1, primary crusher 2, 3, folding station 4, transfer station 6 and collecting and pressing device 7, and possibly other folding stations or a turning station) has its own driven conveyor to promote the blanks in the pass. The processing stations between the insert 1 and the collecting and pressing device 7, ie the primary crushers 2, 3, the folding station 4 and the transfer station 6, contain as conveying two or three parallel with distance from each other in the conveying direction extending belt pairs, each consisting of a lower Belt 8 and an upper belt between which the blanks are held and transported.

Der Einleger 1 enthält einen unteren Riemenförderer, der aus mehreren, mit Abstand nebeneinander angeordneten Förderriemen besteht. Der Riemenförderer zieht die zu verarbeitenden Zuschnitte mit hoher Geschwindigkeit unten aus einem Stapel nacheinander ab und führt sie einzelnen der nachfolgenden Bearbeitungsstationen zu. Die Sammel- und Presseinrichtung 7 enthält zwei maschinenbreite Bandförderer, die als Pressbänder ausgestaltet sind, um den Schuppenstrom aus gefalteten Zuschnitten beim Fördern unter Druck zu halten.The insert 1 includes a lower belt conveyor, which consists of several, spaced apart conveyor belt. The belt conveyor pulls them to processing blanks at high speed down from a stack in succession and leads them to individual subsequent processing stations. The collecting and pressing device 7 includes two machine-wide belt conveyors, which are designed as press belts to keep the shingled flow of folded blanks during conveying under pressure.

In Figur 2 ist eine Bearbeitungsstation mit eingebauter Vorrichtung zum Durchbrechen von Stegen 11 mit zwei Riemenpaaren dargestellt, wobei zur Verdeutlichung auf der linken Seite der obere Förderriemen weggelassen wurde. Jeder der unteren Förderriemen 8 umläuft eine Riemenscheibe 9, die querverschiebbar auf einer angetriebenen Vielkantwelle 10 sitzt. Entsprechend umlaufen die oberen Förderriemen ebenfalls (nicht dargestellte) Riemenscheiben, die querverschiebbar auf einer angetriebenen Vielkantwelle befestigt sind. Beide Riemenpaare können so querpositioniert werden, um ihre Arbeitsposition dem jeweiligen Zuschnittsformat anzupassen. Die Welle 10 wird über einen nicht dargestellten Riementrieb von einem nicht dargestellten Elektromotor angetrieben, der an einer Seitenwand 13 an der Längsseite der Maschine befestigt ist.In FIG. 2 a processing station with built-in device for breaking webs 11 is shown with two pairs of belts, with the upper conveyor belt has been omitted for clarity on the left side. Each of the lower conveyor belt 8 rotates a pulley 9, which sits transversely displaceable on a driven Vielkantwelle 10. Accordingly, the upper conveyor belts also rotate (not shown) pulleys, which are transversely mounted on a driven Vielkantwelle. Both pairs of belts can be positioned transversely to adapt their working position to the respective size of cut. The shaft 10 is driven by a belt drive, not shown, by an electric motor, not shown, which is fixed to a side wall 13 on the longitudinal side of the machine.

In den beiden Seitenwänden 13 ist weiterhin die Vorrichtung 11 zum Durchbrechen von Stegen in Form einer Vierkantprofilwelle 17 drehbar gelagert. Sie wird von einem Servomotor 23 entweder direkt oder über eine nicht dargestellte Kupplung oder einen nicht dargestellten Riemenantrieb angetrieben.In the two side walls 13, the device 11 for breaking webs in the form of a square profile shaft 17 is also rotatably mounted. It is driven by a servo motor 23 either directly or via a clutch, not shown, or a belt drive, not shown.

In der Fig. 3 ist die Vorrichtung 11 zum Durchbrechen der Stege im ausgebauten Zustand dargestellt. Die Vierkantprofilwelle 17 ist mit ihrem Lagerzapfen 16 über Lager 15 in den Seitenwänden 13 der Faltschachtelklebemaschine gelagert. Die Profilwelle 17 weist entweder mehrere Durchgangsbohrungen 21 oder aber eine durchgehende Langlochbohrung 18 (Fig. 2) zur Aufnahme von Werkzeugaufnahmeelementen 19 auf. Diese Werkzeugaufnahmeelemente 19 können beispielsweise Standardschrauben sein. Der Gewindeschaft 25 der Werkzeugaufnahmeelemente 19 ist länger als der Querschnitt der Vierkantprofilwelle 17. Auf den aus der Vierkantprofilwelle 17 herausragenden Teil des Gewindeschaftes 25 des Werkzeugaufnahmeelementes 19 kann das Ausbrechwerkzeug 20 mittels eines Innengewindes 26 aufgeschraubt werden. Der Schraubenkopf 27 der Werkzeugaufnahmeelemente 19 kann beim Zusammenschrauben mit dem Ausbrechwerkzeug 20 mit einer Unterlegscheibe 24 versehen werden. Die Vierkantprofilwelle 17 ist über einen Lagerzapfen 16 mit einem Antrieb 23 verbunden. Dies kann entweder über einen nicht näher dargestellten Riemenantrieb geschehen oder über einen Servomotor 23. Der Servomotor 23 kann entweder direkt oder über eine nicht dargestellte Kupplung mit dem Lagerzapfen 16 verbunden sein.In the Fig. 3 the device 11 is shown for breaking the webs in the disassembled state. The square profile shaft 17 is mounted with its bearing pin 16 via bearings 15 in the side walls 13 of the Faltschachtelklebemaschine. The profile shaft 17 has either a plurality of through holes 21 or a continuous slot bore 18 (FIG. Fig. 2 ) for receiving tool receiving elements 19. These tool receiving elements 19 may be standard screws, for example. The threaded shank 25 of the tool receiving elements 19 is longer than the cross section of the square profile shaft 17. On the protruding from the square profile shaft 17 part of the threaded shank 25 of the tool receiving element 19, the stripping tool 20 can be screwed by means of an internal thread 26.
