Description

Die Erfindung betrifft ein Verfahren zur kontinuierlichen Herstellung von Faltschachteln, wie es im Oberbegriff des Patentanspruches 1 näher angegeben ist, sowie eine entsprechende Vorrichtung zur Ausführung dieses Verfahrens, welche Vorrichtung im Oberbegriff des Patentanspruches 5 definiert ist.The invention relates to a method for the continuous production of folding boxes, as specified in the preamble of claim 1, and a corresponding device for carrying out this method, which device is defined in the preamble of claim 5.

Es sind Faltschachteln bekannt, die mit einem Entnahmefenster versehen sind, durch die der Verbraucher die verpackte Ware entnimmt. Die Faltschachteln sind mit einer entsprechenden Fensteröffnung vorgestanzt, die von dem Verbraucher aufgerissen wird. Insbesondere bei der Verpackung von Papiertüchern haben sich derartige, in dem Verpackungskarton angeordnete Fensteröffnungen als nachteilig erwiesen, weil das durchgezogene Vliesmaterial beim Herausnehmen aus der Fensteröffnung hängenbleiben kann und somit die vorgesehene Funktion, daß ein Tuch das andere beim Herausziehen mitnimmt, nicht mehr gewährleistet ist. Aus diesem Grunde sind für die Verpackung von Papiertüchern Faltschachteln vorgesehen worden, bei denen eine relativ große vorgestanzte Öffnung des Kartons mit einer Kunststoffolie überklebt ist, die eine kleinere Fensteröffnung aufweist. Diese Kunststoffolie ist relativ weich, es besteht dann nicht die Gefahr, daß das durchgezogene Papiertuch an der Fensteröffnung zerreißt.Folding boxes are known which are provided with a removal window through which the consumer removes the packaged goods. The folding boxes are pre-punched with a corresponding window opening that is torn open by the consumer. In particular in the packaging of paper towels, such window openings arranged in the packaging carton have proven to be disadvantageous because the nonwoven material that has been pulled through can get stuck when removed from the window opening and thus the intended function that one cloth takes the other when pulled out is no longer guaranteed. For this reason, folding boxes have been provided for the packaging of paper towels, in which a relatively large pre-punched opening of the cardboard is covered with a plastic film which has a smaller window opening. This plastic film is relatively soft, so there is no risk that the solid paper towel will tear at the window opening.

Bei diesen bekannten Faltschachteln ist die Kunststoffolie, die auf den vorgestanzten Karton aufgeklebt wird, nicht bereits mit ihrer Fensteröffnung versehen, sondern die Fensteröffnung ist lediglich angestanzt. Bei dem Aufkleben der Folie wird an der entsprechenden Stelle des Faltzuschnitts ein Leimauftrag aufgebracht, so daß beim Aufreißen des Kartons das vorgestanzte Teil der Kunststoffolie mit herausgerissen wird und somit erst zu diesem Zeitpunkt die fertige Öffnung in der Kunststoffolie entsteht.In these known folding boxes, the plastic film that is glued to the pre-punched cardboard is not already provided with its window opening, but the window opening is merely punched out. When the film is stuck on, a glue is applied to the corresponding point on the folded blank so that when the cardboard is torn open, the pre-cut part of the plastic film is torn out with it and the finished opening in the plastic film is only created at this point.

Bei dem Herstellungsverfahren für solche Faltschachteln ist es bislang üblich, von einer Vorratsrolle die bereits vorgestanzte Kunststofffolie abzuziehen, in einzelne Abschnitte zu zerschneiden und auf die mit einem entsprechenden Leimauftrag versehenen Faltzuschnitte aufzubringen. Hierzu ist ein separater Arbeitsvorgang zum Anstanzen der Kunststoffolie notwendig. Weiterhin muß bei dem bekannten Verfahren die Kunststoffolie mit einer entsprechenden Druckmarke versehen sein, damit die vorgestanzte Öffnung der Kunststoffolie genau auf den Leimauftrag der Faltschachtel gebracht wird. Diese Druckmarkensteuerung ist relativ kompliziert und teuer. Schließlich hat das bekannte Verfahren den Nachteil, daß der Klebstoffauftrag um die vorgestanzte Öffnung in dem Karton der Faltschachtel relativ nahe am Rande der Öffnung zu erfolgen hat, damit der Leim nicht über die Kunststoffolie hinausreicht und die im nächstfolgenden Arbeitsgang ankommenden Kartonzuschnitte an diesem Leimauftrag nicht kleben bleiben. Diese Positionierung des Leimauftrags hat andererseits aber den Nachteil, daß in der Packmaschine das Füllgut an der überstehenden Folie hängenbleiben und damit maschinelle Störungen verursachen kann.In the manufacturing process for such folding boxes, it has hitherto been customary to pull the pre-punched plastic film from a supply roll, cut it into individual sections and apply it to the folding blanks provided with an appropriate glue application. This requires a separate operation to punch the plastic film. Furthermore, in the known method, the plastic film must be provided with an appropriate printing mark, so that the pre-punched opening of the plastic film is brought precisely onto the glue application of the folding box. This control of print marks is relatively complicated and expensive. Finally, the known method has the disadvantage that the adhesive application around the pre-punched opening in the carton of the folding box has to take place relatively close to the edge of the opening so that the glue does not extend beyond the plastic film and the carton blanks arriving in the next operation do not stick to this glue application stay. On the other hand, this positioning of the glue application has the disadvantage that the filling material gets stuck on the protruding film in the packaging machine and can therefore cause machine malfunctions.

Aufgabe der Erfindung ist dementsprechend, ein Verfahren und eine Vorrichtung zur kontinuierlichen Herstellung von Faltschachteln mit einem eingeklebten Entnahmefenster aus flexibler Folie anzugeben, bei dem kein Vorstanzen der Kunststoffolie erforderlich ist und das die erforderliche Genauigkeit in der Positionierung der Kunststoffolie auch ohne eine besondere Druckmarkensteuerung erlaubt.The object of the invention is accordingly to provide a method and a device for the continuous production of folding boxes with a glued-in removal window made of flexible film, in which no pre-punching of the plastic film is required and which allows the required accuracy in the positioning of the plastic film even without a special print mark control.

Diese Aufgabe wird mit einem Verfahren gemäß Patentanspruch 1 und durch eine Vorrichtung gemäß Patentanspruch 5 gelöst.This object is achieved with a method according to claim 1 and with a device according to claim 5.

Weitere, vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sowie bevorzugte Vorrichtungen zur Ausführung dieses Verfahrens sind in den Unteransprüchen angegeben.Further advantageous refinements of the method according to the invention and preferred devices for carrying out this method are specified in the subclaims.

Das erfindungsgemäße Verfahren sieht vor, daß die aufzuklebende Folie als ungestanztes Band von einer Vorratsrolle abgezogen wird und unmittelbar vor dem Zerteilen in einzelne Abschnitte entsprechend der Fensteröffnung angestanzt wird. Dies geschieht im Zusammenwirken mit der Maschine bzw. der Walze, mit der die einzelnen Abschnitte der Kunststoffolie auf die Faltzuschnitte aufgetragen werden. Da die Einheiten zum Anstanzen der Fensteröffnung und die Walze zum Auftragen der Kunststoffolien-Abschnitte mechanisch starr miteinander verbunden sind und damit die einzelnen Abschnitte der Kunststoffolie paßgenau vorbereiten können, erübrigt sich eine besondere Druckmarkensteuerung, die sonst zur Positionierung der Kunststoffolie notwendig wäre. Außerdem ist die Positionierung sehr viel genauer und eine Addition von Toleranzen wie bei dem bekannten Verfahren kann nicht auftreten. Weiterhin wird ein Arbeitsgang eingespart, nämlich das vorbereitende Abziehen einer noch ungestanzten Folie, deren Stanzen mit einer Stanzwalze und ihr anschließendes Wiederaufrollen zu einer Vorratsrolle von vorgestanzten Folienmaterial.The method according to the invention provides that the film to be glued is drawn off from a supply roll as a non-punched tape and is punched into individual sections in accordance with the window opening immediately before being divided. This takes place in cooperation with the machine or the roller, with which the individual sections of the plastic film are applied to the folding blanks. Since the units for punching the window opening and the roller for applying the plastic film sections are mechanically rigidly connected to one another and thus can prepare the individual sections of the plastic film with a precise fit, a special print mark control, which would otherwise be necessary for positioning the plastic film, is unnecessary. In addition, the positioning is much more precise and tolerances cannot be added as in the known method. Furthermore, one operation is saved, namely the preparatory pulling off of a film that has not yet been punched, its punching with a punching roll and its subsequent rewinding to a supply roll of pre-punched film material.

Das erfindungsgemäße Verfahren vollzieht sich in der Weise, daß von der Vorratsrolle das Folienband mit Hilfe entsprechender Vorschubwalzen abgezogen wird, an einer rotierenden Stanzwalze vorbeigeführt wird und dann mit Hilfe eines rotierenden und eines feststehenden Messers in einzelne Abschnitte vorgegebener Länge zerteilt wird. Die abgeschnittenen Teile der Kunststoffolie werden von einer Vakuumwalze erfaßt und von ihr auf die mit dem Leimauftrag versehenen Faltzuschnitte aufgetragen.The process according to the invention is carried out in such a way that the film strip is pulled off the supply roll with the aid of appropriate feed rollers, is guided past a rotating punching roll and is then divided into individual sections of a predetermined length with the aid of a rotating and a fixed knife. The cut-off parts of the plastic film are gripped by a vacuum roller and applied by it to the folding blanks provided with the glue application.

Die zur Ausführung dieses Verfahrens vorgesehene Vorrichtung weist an dem rotierenden Messer ein Antriebsritzel auf, das ein entsprechendes Ritzel der Stanzmesserwalze antreibt. Zwischen dem Ritzel des umlaufenden Messers und dem der Stanzmesserwalze ist vorzugsweise ein Zwischenritzel angeordnet. Aufgrund dieser direkten mechanischen Übertragung der Bewegung des umlaufenden Messers auf die Stanzmesserwalze ist eine unmittelbare, unveränderliche Zuordnung zwischen der Positionierung der angestanzten Fensteröffnung und dem Anfang bzw. dem Ende eines einzelnen Folienabschnittes gegeben. Eine besondere Steuerung zum Abschneiden der Folie ist damit nicht notwendig.The device provided for executing this method has a drive pinion on the rotating knife, which drives a corresponding pinion of the punching knife roller. An intermediate pinion is preferably arranged between the pinion of the rotating knife and that of the punch knife roller. Based on these Direct mechanical transmission of the movement of the rotating knife to the die-cutting knife roller provides an immediate, unchangeable assignment between the positioning of the punched window opening and the beginning or end of a single film section. A special control for cutting the film is not necessary.

Im folgenden wird nun das erfindungsgemäße Verfahren anhand des in den Figuren dargestellten Ausführungsbeispiels für die Ausführung des Verfahrens dienende Vorrichtung beschrieben und näher erläutert. Es zeigt

  • Fig. 1 eine schematische Darstellung einer Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens
  • Fig. 2 eine Einzelheit aus der erfindungsgemäßen Vorrichtung
  • Fig. 3 einen Schnitt A-A nach Fig. 2.
The method according to the invention will now be described and explained in more detail below on the basis of the exemplary embodiment illustrated in the figures for the device used to carry out the method. It shows
  • Fig. 1 is a schematic representation of an apparatus for performing the method according to the invention
  • Fig. 2 shows a detail from the device according to the invention
  • 3 shows a section AA according to FIG. 2.

Fig. 1 zeigt schematisch eine Vorrichtung gemäß der Erfindung, die zur Ausführung des erfindungsgemäßen Verfahrens dient. Auf der linken Seite befindet sich eine Transportvorrichtung 9, beispielsweise ein Förderband, das die einzelnen Faltzuschnitte zu der Klischeerolle 8 transportiert. Die Klischeerolle 8 wird über eine Auftragsrolle 21 mit Leim aus einem Leimvorrat 22 versehen. Die rotierende Klischeerolle 8 überträgt die entsprechende Leimschicht auf die vorgesehenen Stellen der Faltzuschnitte 1.Fig. 1 shows schematically a device according to the invention, which is used to carry out the method according to the invention. On the left side there is a transport device 9, for example a conveyor belt, which transports the individual folding blanks to the cliché roll 8. The cliché roll 8 is provided with glue from a glue supply 22 via an application roll 21. The rotating cliché roller 8 transfers the corresponding layer of glue to the intended locations of the folding blanks 1.

Die Vorrichtung umfaßt weiter eine Vorratsrolle 3, auf der ein noch ungestanztes Folienband 2 aufgewickelt ist.The device further comprises a supply roll 3, on which a film strip 2 which has not yet been punched is wound.

Dieses Folienband 2 läuft zwischen einer freilaufenden Gegenrolle 18 und der Stanzmesserwalze 4. Die Stanzmesserwalze 4 wird über ein Ritzel 11 und ein auf einer Zwischenwelle 12 gelagertes Zwischenritzel 13 von dem Ritzel 10 des rotierenden Messers 5 angetrieben. Durch den entsprechenden Vorschub wird das Folienband 2 von der Vorratsrolle 3 abgezogen. Nachdem auf das Folienband 2 von der Stanzmesserwalze 4 die entsprechenden Fensteröffnungen angestanzt sind, wird die Folie zwischen dem rotierenden Messer 5 und dem feststehenden Messer 6 in einzelne Teilabschnitte zerschnitten. Diese Abschnitte werden von der Vakuumwalze 7 erfaßt. Sie weist an ihrer Mantelfläche einzelne Öffnungen auf und in ihr herrscht ein Unterdruck, so daß die Folie an der Mantelfläche dieser Vakuumwalze haften. Von der Vakuumwalze werden die einzelnen Abschnitte der Folie auf die Faltzuschnitte 1 aufgetragen. Sie werden sodann von der Transportvorrichtung 9 weiterbefördert.This foil strip 2 runs between a free-running counter roller 18 and the punch knife roller 4. The punch knife roller 4 is driven by the pinion 10 of the rotating knife 5 via a pinion 11 and an intermediate pinion 13 mounted on an intermediate shaft 12. The film feed 2 is pulled off the supply roll 3 by the corresponding feed. After the corresponding window openings have been punched onto the foil strip 2 by the punch knife roller 4, the foil is cut into individual sections between the rotating knife 5 and the fixed knife 6. These sections are gripped by the vacuum roller 7. It has individual openings on its outer surface and a negative pressure prevails in it, so that the film adheres to the outer surface of this vacuum roller. The individual sections of the film are applied to the folding blanks 1 by the vacuum roller. They are then transported on by the transport device 9.

Die Fig. und 3 zeigen einen Teilausschnitt aus der erfindungsgemäßen Vorrichtung. Das Stanzmesser 4 ist in zwei Kulissensteinen 14 gelagert und kann nach dem Wegschwenken der Spannlaschen 15 ausgewechselt werden. Diese Spannlaschen 15 sind mit Spannschrauben 16 angezogen. Die Kulissenführung 17 ist auf der Achse 19 der Gegenrolle 18 gelagert. Entsprechend der Bemessung des Langloches 23 kann die Kulissenführung 17 geschwenkt werden. Durch diese Schwenkbewegung wird das Zahnritzel 11 an der Stanzmesserwalze 4 in das auf der Zwischenwelle 12 gelagerte Zwischenritzel 13 eingeschwenkt und befestigt. Dieses Zwischenritzel 13 wird wiederum, wie in Fig. 1 dargestellt ist, von dem Ritzel 10, das an dem umlaufenden Messer 5 angebracht ist, angetrieben.FIGS. 3 and 3 show a partial section from the device according to the invention. The punching knife 4 is mounted in two sliding blocks 14 and can be exchanged after the tensioning straps 15 have been pivoted away. These clamping tabs 15 are tightened with clamping screws 16. The link guide 17 is mounted on the axis 19 of the counter roller 18. According to the dimensioning of the elongated hole 23, the link guide 17 can be pivoted. As a result of this pivoting movement, the toothed pinion 11 on the punching knife roller 4 is pivoted into and fastened in the intermediate pinion 13 mounted on the intermediate shaft 12. This intermediate pinion 13 is in turn, as shown in FIG. 1, driven by the pinion 10, which is attached to the rotating knife 5.

Die Übersetzungsverhältnisse zwischen dem Antriebsritzel 10, dem Zwischenritzel 13 und dem Zahnritzel 11 sind beispielsweise 1 : 1 : 1.The gear ratios between the drive pinion 10, the intermediate pinion 13 and the toothed pinion 11 are, for example, 1: 1: 1.

Die Fig. 3 zeigt einen Schnitt A-A nach Fig. 2. Es ist erkennbar, daß die Stanzmesserwalze 4 in ihrer Mitte das Stanzmesser 20 trägt und in Kulissensteinen 14 auswechselbar gelagert ist. Die Gegenrolle 18 ist auf einer Achse 19 aufgesteckt, beispielsweise verkeilt.FIG. 3 shows a section A-A according to FIG. 2. It can be seen that the punch knife roller 4 carries the punch knife 20 in its center and is interchangeably mounted in sliding blocks 14. The counter roller 18 is mounted on an axis 19, for example wedged.
