Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Abstapeln von Wellpappenabschnitten auf mindestens zwei nebeneinander angeordnete Stapel in einem Formatableger einer Wellpappenanlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for stacking corrugated cardboard sections onto at least two stacks arranged next to one another in a format stacker of a corrugated cardboard system according to the preamble of patent claim 1.

Aus der US-PS 3 550 493 ist bekanntgeworden, eine Wellpappenbahn in einer Längsschneid- und Rillmaschine in einzelne Nutzen aufzuteilen, die üblicherweise in einer Transportvorrichtung vor dem Querschneider gruppenweise unterschiedlich abgelenkt und dem Querschneider zugeführt werden. Ein Teil der Nutzen wird unteren Querschneidwerkzeugen und ein anderer Teil oberen Querschneidwerkzeugen zugeführt. Den Querschneidwerkzeugen sind Fördervorrichtungen zugeordnet, welche die Wellpappenabschnitte in geschuppter Form zu einem Formatableger fördern. Der Anzahl der Nutzen entspricht die Anzahl der Schuppenströme auf dem Förderer zum Formatableger. Der Formatableger bildet entsprechend der Anzahl der Nutzen einzelne relativ eng nebeneinanderstehende Stapel. Werden zum Beispiel drei Schuppenströme zu einer ersten Stapelplattform gefördert, werden auf dieser drei Stapel nebeneinander gebildet.From US Pat. No. 3,550,493 it has become known to divide a corrugated cardboard web in a slitting and creasing machine into individual panels which are usually deflected in groups in a transport device in front of the cross cutter and fed to the cross cutter. Some of the benefits are fed to lower cross-cutting tools and another part to upper cross-cutting tools. The cross-cutting tools are assigned conveying devices which convey the corrugated cardboard sections in a scaled form to a format depositor. The number of benefits corresponds to the number of scale flows on the conveyor to the format deposit. The format depositor forms individual stacks that are relatively close to each other in accordance with the number of uses. If, for example, three streams of shingles are conveyed to a first stacking platform, three stacks are formed side by side on this.

Die Stapel im Formatableger erreichen eine beträchtliche Höhe. Vor allem bei schmalen Formaten besteht jedoch die Gefahr, daß sie verrutschen oder gar umkippen.The stacks in the format tray reach a considerable height. Especially in the case of narrow formats there is a risk that they will slip or even tip over.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Abstapeln von Wellpappenabschnitten auf mindestens zwei nebeneinander angeordnete Stapel in einer Wellpappenanlage zu schaffen, die eine Stabilisierung von nebeneinander angeordneten Stapeln bewirkt, und zwar unabhängig von der Art und dem Aufbau der Längsschneid-und Rillmaschine. Die Vorrichtung soll auch in bestehende Wellpappenanlagen eingebaut werden können.The invention is therefore based on the object of providing a device for stacking corrugated cardboard sections onto at least two stacks arranged next to one another in a corrugated cardboard system, which stabilizes stacks arranged next to one another, regardless of the type and structure of the longitudinal cutting and creasing machine. The device should also be able to be installed in existing corrugated cardboard systems.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Kennzeichnungsteils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Bei der erfindungsgemäßen Vorrichtung ist oberhalb der Transportvorrichtung zwischen Längsschneid- und Rillmaschine und Querschneider mindestens eine Aufbringvorrichtung angeordnet, die quer zur Bahnrichtung verfahrbar gelagert ist. Mit Hilfe der Aufbringvorrichtung können Klebestreifen, selbstklebende Papierabschnitte oder dergleichen auf benachbarte Nutzen aufgebracht werden. Die Klebestreifen, selbstklebenden Papierabschnitte oder dergleichen bilden Verbindungsstege zwischen den Stapeln, wodurch den Stapeln gegenseitig Stabilität verliehen wird.In the device according to the invention, at least one application device is arranged above the transport device between the slitting and creasing machine and cross cutter and is mounted such that it can be moved transversely to the web direction. With the help of the application device, adhesive strips, self-adhesive paper sections or the like can be applied to adjacent panels. The adhesive strips, self-adhesive paper sections or the like form connecting webs between the stacks, as a result of which the stacks are given mutual stability.

Aus der DE-OS 3 213 895 ist bekanntgeworden, zwischen benachbarten Nutzen aus Papier, die in einem Ableger leporelloartig zu einem Stapel gefaltet werden, dadurch Verbindungsstege zu bilden, daß das Schneidmesser mit entsprechenden Aussparungen versehen ist. Eine Anwendung dieses Verfahrens auf Wellpappenanlagen würde zu einem großen Aufwand für die Längsschneid- und Rillmaschine führen. Eine nachträgliche Umwandlung der Längsschneid- und Rillmaschine bei bestehenden Wellpappenanlagen würde den Aufwand noch erhöhen. Außerdem müßte während des Umbaus die Produktion stillgesetzt werden. Durch das perforierte Längsschneiden lasse sich der Stegabstand und die Lage der Stege relativ zu einem Format nicht verändern.From DE-OS 3 213 895 it has become known to form connecting webs between adjacent sheets of paper which are folded like a leporello into a stack in a branch, in that the cutting knife is provided with corresponding cutouts. Applying this method to corrugated cardboard systems would result in great expense for the slitting and creasing machine. A subsequent conversion of the slitting and creasing machine in existing corrugated cardboard systems would increase the effort even more. In addition, production would have to be stopped during the renovation. The perforated longitudinal cutting means that the spacing between the bars and the position of the bars cannot be changed in relation to a format.

Die erfindungsgemäße Vorrichtung hat den Vorteil, daß sie in bestehende Wellpappenanlagen ohne weiteres und ohne großen Aufwand eingebaut werden kann, ohne daß es zu einer Produktionsunterbrechung kommt. Die Klebestreifen brauchen nur eine sehr geringe Dicke und Breite haben, um den gewünschten Stabilitätseffekt zu bewirken. Die erfindungsgemäße Aufbringvorrichtung hat ferner den Vorteil, daß die Lage und die Häufigkeit des Aufbringens der Klebestreifen willkürlich bestimmbar sind. So können die Klebestreifen zum Beispiel an die Stirnseiten gelegt werden, damit sie beim Trennen der Stapel leichter getrennt werden können, beispielsweise von Hand.The device according to the invention has the advantage that it can be installed in existing corrugated cardboard systems easily and without great effort, without causing an interruption in production. The adhesive strips only need to have a very small thickness and width in order to achieve the desired stability effect. The application device according to the invention also has the advantage that the position and frequency of application of the adhesive strips can be determined arbitrarily. For example, the adhesive strips can be placed on the end faces so that they can be separated more easily when the stacks are separated, for example by hand.

Die Verklebung der Klebestreifen oder der selbstklebenden Papierabschnitte braucht nur sehr schwach zu sein, da sie nur sicherstellen soll, daß die miteinander verbundenen Wellpappenabschitte gemeinsam abgestapelt werden. Anschließend sorgt der Druck des Stapels für eine feste Verbindung der Papierabschnitte mit dem Stapel.The gluing of the adhesive strips or the self-adhesive paper sections need only be very weak, since it is only intended to ensure that the corrugated cardboard sections which are connected to one another are stacked together. Then the pressure of the stack ensures that the paper sections are firmly connected to the stack.

Da bei Formatwechseln sich auch die Lage der Trennschnitte ändern kann, ist die Aufbringvorrichtung quer zur Bahnlaufrichtung verfahrbar. Eine Ausgestaltung der Erfindung sieht hierzu vor, daß eine Positioniervorrichtung vorgesehen ist zur Verstellung der Aufbringvorrichtung in Übereinstimmung mit der Position der Trennwerkzeuge in der Längsschneid- und Rillmaschine. Die Positionierung kann zum Beispiel von Hand erfolgen oder automatisch über Synchronisation mit der Positionierung der Trennwerkzeuge.Since the position of the separating cuts can also change when the format is changed, the application device can be moved transversely to the web running direction. An embodiment of the invention provides for this that a positioning device is provided for adjusting the application device in accordance with the position of the cutting tools in the slitting and creasing machine. The positioning can be done manually, for example, or automatically via synchronization with the positioning of the cutting tools.

Die Kantenlage der Wellpappenbahn schwankt. Es ist daher erforderlich, entweder die Kantenlage zu korrigieren oder - der übliche Weg - die Längsschneid- und Rillmaschine der Kantenlage nachzufahren. Eine Ausgestaltung der Erfindung sieht vor, daß eine Bahnkantensteuerung die Aufbringvorrichtung über die Positioniervorrichtung quer zur Förderrichtung synchron zur Längsschneid-und Rillmaschine nachfährt.The edge position of the corrugated cardboard web fluctuates. It is therefore necessary to either correct the edge position or - the usual way - to follow the slitting and creasing machine to the edge position. One embodiment of the invention provides that a web edge control tracks the application device transversely to the conveying direction synchronously with the slitting and creasing machine via the positioning device.

Die Erfindung wird nachfolgend anhand von Zeichnungen näher erläutert.

  • Fig. 2 zeigt schematisch die Draufsicht auf eine Stapelplattform eines Formatablegers mit drei nebeneinanderliegenden Stapeln.
  • Fig. 3 zeigt die Seitenansicht der Anordnung nach Fig. 2.
The invention is explained in more detail below with reference to drawings.
  • Fig. 1 shows a side view schematically a part of a corrugated cardboard system with a device according to the invention.
  • Fig. 2 shows schematically the top view of a stacking platform of a format depositor with three adjacent stacks.
  • FIG. 3 shows the side view of the arrangement according to FIG. 2.

In Fig. 1 ist schematisch eine Längsschneid- und Rillmaschine 10 dargestellt, der eine Wellpappenbahn 11 zugeführt wird. Die Wellpappenbahn kommt von einer üblichen Wellpappenmaschine. Einzelheiten der Längsschneid- und Rillmaschine 10 werden nicht beschrieben, da sie Stand der Technik ist. Die Maschine 10 bzw. deren Werkzeugeinheiten sind relativ zur Kantenlage der Wellpappenbahn 11 in Querrichtung verfahrbar, um der Kantenlage nachgefahren zu werden. Hierfür ist eine nicht gezeigte Steuerung vorgesehen. Die Längsschneid- und Rillmaschine 10 schneidet die Wellpappenbahn 11 in einzelne Nutzen. Im vorliegenden Fall sei angenommen, daß sie die Wellpappenbahn 11 in sechs Nutzen unterteilt. Die Nutzen werden einer Transportvorrichtung 12 zugeführt, welche ein endloses Vakuumband 13 enthält zum Transport der Nutzen zu einem Querschneider 14. Die Transportvorrichtung 12 enthält eine Umlenkwalze 15, der zwei Umlenkflächen 16, 17 nachgeordnet sind. Die Umlenkflächen 16, 17 sind nebeneinander angeordnet. Die Umlenkfläche 16 lenkt zum Beispiel die linken drei Nutzen zu einer oberen Einheit 17 des Querschneiders 14, während die nach unten gerichtete Umlenkfläche 17 die drei anderen rechten Nutzen zu einer unteren Einheit 18 des Querschneiders 14 lenkt. Über eine untere und eine obere Förderstrecke, die hier nicht gezeigt sind, werden die im Querschneider 14 erzeugten Wellpappenabschnitte in geschuppter Form einem ebenfalls nicht gezeigten Formatableger zugeführt. Der Formatableger besitzt zwei hintereinander angeordnete Stapelplattformen, auf denen im beschriebenen Beispiel jeweils drei Stapel gebildet werden. In den Figuren 2 und 3 ist eine Stapelplattform 19 schematisch dargestellt. Sie zeigt die drei Stapel 20, 21 und 22. Falls keine besonderen Maßnahmen ergriffen werden, besteht die Gefahr, daß die Stapel 20 bis 22 zur Seite wegkippen können. Daher sind oberhalb des Vakuumbandes 13 Aufbringvorrichtungen 23 angeordnet. Bei sechs Nutzen sind insgesamt fünf Aufbringvorrichtungen notwendig, da fünf Trennschnitte in der Längsschneid- und Rillmaschine erfolgen. Die Aufbringvorrichtungen 23 sind mit Hilfe von Schienen 24 in Querrichtung verfahrbar. Die Einstellung der Aufbringvorrichtungen 23, die unabhängig voneinander verstellbar sind, erfolgt mit geeigneten Positioniervorrichtungen (nicht gezeigt), welche bei einer Änderung der Schneidwerkzeuge den Aufbringvorrichtungen 23 entsprechend nachfahren, damit sie jeweils über eine Lücke benachbarter Nutzen angeordnet sind. Das Einstellen der Aufbringvorrichtungen 23 kann aber auch von Hand durchgeführt werden. Die Verfahrbarkeit der Aufbringvorrichtungen 23 wird darüber hinaus mit der der Längsschneid- und Rillmaschine 10 synchronisiert, um der Kantenlage der Wellpappenbahn 10 nachzufahren. Mit Hilfe der Aufbringvorrichtung 23 werden einzelne leicht lösbare Klebestreifen oder dergleichen über den Spalt zwischen benachbarten Nutzen aufgebracht. Die Abstände zwischen den dadurch gebildeten Brücken zwischen den Nutzen werden mit Hilfe einer geeigneten Steuervorrichtung eingestellt. Die Abstände können stückzahlabhängig oder längenabhängig bestimmt sein. In jedem Fall werden dadurch zwischen einigen benachbarten Wellpappenabschnitten Verbindungsstege gebildet, die in den Figuren 2 und 3 bei 25 angedeutet sind. Sie führen zu einer Stabilität der Stapel 20 bis 22. Andererseits können sie jedoch sehr leicht durchschnitten oder entfernt werden, wenn die Stapel 20 bis 22 der weiteren Verarbeitung zugeführt werden. Bei einem stückzahlabhängigen Aufbringen können die Verbindungsstege 25 nahe den Außenkanten der Stapel 20 bis 22 gelegt werden, wo sie dann von Hand leicht durchtrennt werden können, wenn die Stapel 20 bis 22 der weiteren Bearbeitung zugeführt werden.In Fig. 1, a longitudinal cutting and creasing machine 10 is shown schematically, to which a corrugated cardboard web 11 is fed. The corrugated cardboard web comes from a conventional corrugated cardboard machine. Details of the slitting and creasing machine 10 are not described since they are state of the art. The Machine 10 or its tool units can be moved in the transverse direction relative to the edge position of the corrugated cardboard web 11 in order to be traced back to the edge position. A controller, not shown, is provided for this. The slitting and creasing machine 10 cuts the corrugated cardboard web 11 into individual uses. In the present case it is assumed that it divides the corrugated cardboard web 11 into six uses. The blanks are fed to a transport device 12, which contains an endless vacuum belt 13 for transporting the blanks to a cross cutter 14. The transport device 12 contains a deflection roller 15, which is followed by two deflection surfaces 16, 17. The deflection surfaces 16, 17 are arranged side by side. For example, the deflection surface 16 directs the three left-hand benefits to an upper unit 17 of the cross cutter 14, while the downward deflection surface 17 directs the three other right-hand benefits to a lower unit 18 of the cross cutter 14. Via a lower and an upper conveyor line, which are not shown here, the corrugated cardboard sections produced in the cross cutter 14 are fed in a scaled form to a format stacker, also not shown. The format depositor has two stacking platforms arranged one behind the other, on which three stacks are formed in the example described. A stacking platform 19 is shown schematically in FIGS. 2 and 3. It shows the three stacks 20, 21 and 22. If no special measures are taken, there is a risk that the stacks 20 to 22 can tip over to the side. Therefore, 13 application devices 23 are arranged above the vacuum belt. With six uses, a total of five application devices are necessary, since five separating cuts are made in the slitting and creasing machine. The application devices 23 can be moved in the transverse direction with the aid of rails 24. The setting of the application devices 23, which can be adjusted independently of one another, is carried out using suitable positioning devices (not shown) which, when the cutting tools are changed, follow the application devices 23 accordingly, so that they are each arranged over a gap of adjacent uses. The setting of the application devices 23 can also be carried out by hand. The movability of the application devices 23 is also synchronized with that of the slitting and creasing machine 10 in order to track the edge position of the corrugated cardboard web 10. With the aid of the application device 23, individual, easily detachable adhesive strips or the like are applied over the gap between adjacent panels. The distances between the bridges thus formed between the panels are set using a suitable control device. The distances can be determined depending on the number of pieces or length. In any case, connecting webs are formed between some adjacent corrugated cardboard sections, which are indicated at 25 in FIGS. 2 and 3. They lead to the stability of the stacks 20 to 22. On the other hand, however, they can be cut or removed very easily if the stacks 20 to 22 are sent for further processing. In the case of a quantity-dependent application, the connecting webs 25 can be placed near the outer edges of the stacks 20 to 22, where they can then be easily severed by hand when the stacks 20 to 22 are fed for further processing.
