Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Steige aus Pappe, bestehend aus einem Boden und vier Seitenwänden, mit Holzstützen in den vier Ecken, an deren in das Innere der Steige zeigenden Seite eine von einer Seitenwand abgebogene Lasche anliegt, bei dem die Steige aus einem einteiligen Zuschnitt aufgerichtet und die Seiten der Holzstützen mit den sie umgebenden Pappteilen verklebt werden.The invention relates to a method for producing a crate made of cardboard, consisting of a bottom and four side walls, with wooden supports in the four corners, on the side of which points into the interior of the crate, a tab bent from a side wall rests, in which the crate consists of a one-piece cut erected and the sides of the wooden supports are glued to the cardboard parts surrounding them.

Die Erfindung betrifft weiterhin eine Vorrichtung zur Durchführung des Verfahrens.The invention further relates to an apparatus for performing the method.

Es ist an sich bekannt, eine Steige aus Pappe in den Ecken mit Holzstützen zu verkleben, um so eine Verstärkung, insbesondere hinsichtlich der Stapelbarkeit, zu erreichen. Derartige Steigen könnten in vielen Anwendungsbereichen eingesetzt werden, in denen bisher auf reine Holzsteigen zurückgegriffen werden muß, weil die kombinierten Steigen nicht maschinell und daher preisgünstig genug herstellbar sind.It is known per se to glue a cardboard crate to wooden supports in the corners in order to achieve reinforcement, in particular with regard to stackability. Such crates could be used in many areas of application, in which previously only pure Wooden crates must be used because the combined crates cannot be manufactured mechanically and therefore inexpensively enough.

Um für das Einführen der Hdzstützen einen ausreichenden Raum zur Verfügung zu haben, ist vorgeschlagen worden, während des Aufrichtens der Steige die Holzstützen zuzuführen und beim letzten Aufrichtungsschritt die Verklebung mit den Holzstützen durchzuführen. Es hat sich jedoch gezeigt, daß dieses Verfahren maschinell nur außerordentlich schwierig zu beherrschen ist, so daß eine nach diesem Verfahren arbeitende Maschine nicht mit der ausreichenden Zuverlässigkeit für die Massenproduktion erstellt werden kann.In order to have sufficient space available for the insertion of the wooden supports, it has been proposed to feed the wooden supports during the erection of the crates and to carry out the gluing with the wooden supports in the last erection step. However, it has been shown that this process is extremely difficult to master by machine, so that a machine operating according to this process cannot be produced with sufficient reliability for mass production.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs erwähnten Art zu erstellen, die für die Massenproduktion von Pappsteigen mit Holzstützen geeignet sind.The invention is therefore based on the object of creating a method and a device of the type mentioned at the outset which are suitable for the mass production of cardboard trays with wooden supports.

Diese Aufgabe wird mit einem Verfahren der eingangs erwähnten Art gelöst, das folgende Verfahrensschritte aufweist:

  • - Die Steige wird aus dem Zuschnitt vollständig aufgerichtet und unter Bildung von oben offenen Aufnahmekammern für die Holzstützen verklebt;
  • - die Innenseiten der Aufnahmekammern werden mit Klebstoff beschichtet;
  • - anschließend werden die Holzstützen von oben unter gleichzeitigem Auseinanderdrücken der oberen Ränder der Wandungen der Aufnahmekammern in die Aufnahmekammern eingeführt.
This object is achieved with a method of the type mentioned at the outset, which has the following method steps:
  • - The crate is completely erected from the blank and glued to form open-top receiving chambers for the wooden supports;
  • - The inside of the receiving chambers are coated with adhesive;
  • - Then the wooden supports are inserted into the receiving chambers from above while simultaneously pushing apart the upper edges of the walls of the receiving chambers.

Das erfindungsgemäße Verfahren sieht also vor, die Steige vollständig aufzurichten. Dies hat an sich den Nachteil, daß die Aufnahmekammern nur in ihrer die Holzstützen eng umschließenden Größe zur Verfügung stehen. Ein maschinelles Einfahren der Holzstützen in diese oben offenen Aufnahmekammern ist nicht ohne weiteres möglich, weswegen das Einsetzen der Holzstützen in die fertig aufgerichtete Steige nicht in Betracht gezogen worden ist.The method according to the invention therefore provides for the crate to be erected completely. This has the disadvantage in itself that the receiving chambers are only available in their size which closely surrounds the wooden supports. It is not readily possible for the wooden supports to be automatically retracted into these open-topped compartments, which is why the insertion of the wooden supports into the fully erected tray has not been considered.

Erfindungsgemäß wird jedoch beim Einführen der Holzstützen gleichzeitig die entsprechende Aufnahmekammer dadurch aufgeweitet, daß zumindest die oberen Ränder der Wandungen der Aufnahmekammer beim Einführen der Holzstützen auseinandergedrückt werden. Das Auseinanderdrücken wird erleichtert, wenn die Seitenwände der Aufnahmekammern noch nicht vollständig verklebt sind, wenn also insbesondere eine Seitenwand der Aufnahmekammer noch nicht fixiert ist. Insbesondere kann bei dreikantigen Holzstützen der von einer Seitenwand abgebogene Lappen frei bleiben, d. h. nicht mit der an der Ecke benachbarten Seitenwand verbunden werden. Mit Hilfe dieser Lasche kann die Aufnahmekammer leicht beim Einführen der Holzstützen aufgeweitet werden.According to the invention, however, when the wooden supports are inserted, the corresponding receiving chamber is expanded at the same time that at least the upper edges of the walls of the receiving chamber are pressed apart when the wooden supports are inserted. The pushing apart is facilitated if the side walls of the receiving chambers are not yet completely glued, in particular if one side wall of the receiving chamber is not yet fixed. In particular, in the case of triangular wooden supports, the tab bent from a side wall can remain free; H. not be connected to the side wall adjacent to the corner. With the help of this tab, the receiving chamber can be easily expanded when the wooden supports are inserted.

Das erfindungsgemäße Verfahren läßt sich mit herkömmlichen Leimarten ausführen, wenn anschließend ein auf die Holzstütze gerichteter Druck auf die Laschen und ein Gegendruck von außen auf die Seitenwände im Eckbereich ausgeübt wird.The method according to the invention can be carried out with conventional types of glue if a pressure on the brackets directed onto the wooden support and a counter pressure from outside are subsequently exerted on the side walls in the corner area.

Eine besonders zuverlässige Verbindung zwischen der Steige und den Holzstützen läßt sich ohne zusätzlichen Verfahrensgang dadurch erreichen, daß beim Ausüben des Gegendrucks auf die Seitenwände mindestens jeweils eine Seitenwand im Eckbereich mit der Holzstütze durch Heftung verbunden wird. Die Heftung wird dabei vorzugsweise an einer Längsseitenwand mit Hilfe eines Tackers vorgenommen.A particularly reliable connection between the crate and the wooden supports can be achieved without an additional process step in that when the counterpressure is exerted on the side walls, at least one side wall in the corner area is connected to the wooden support by stitching. The stapling is preferably carried out on a longitudinal side wall with the aid of a stapler.

Die der Erfindung zugrunde liegende Aufgabe wird weiterhin durch eine Vorrichtung zur Durchführung des Verfahrens gelöst, die mit den Aufnahmekammern der aufgerichteten Steige jeweils fluchtende Zuführungsschächte für die Holzstützen aufweist, die an ihrem unteren Ende jeweils mit elastischen, nach innen gerichteten Laschen versehen sind, die mit dem zugehörigen Schacht in das Innere der betreffenden Aufnahmekammer absenkbar und durch die nach unten gedrückten Holzstützen auseinanderdrückbar sind.The object on which the invention is based is further achieved by a device for carrying out the method, which in each case has aligned feed shafts for the wooden supports which are aligned with the receiving chambers of the erected crates and which are each provided at their lower end with elastic, inwardly directed tabs which are provided with the associated shaft can be lowered into the interior of the receiving chamber concerned and can be pushed apart by the wooden supports that are pressed downwards.

Die erfindungsgemäße Vorrichtung erlaubt die Durchführung des erfindungsgemäßen Verfahrens ohne irgendwelche Steuerungsmaßnahmen für das Aufweiten der Aufnahmekammer. Durch die nach unten gedrückten Holzstützen wird die Aufweitung mit Hilfe der elastischen Laschen automatisch durchgeführt.The device according to the invention allows the method according to the invention to be carried out without any control measures for expanding the receiving chamber. The wooden supports are pushed down and the expansion is carried out automatically using the elastic tabs.

Zur Durchführung des für die Klebeverbindung vorgesehenen Andrucks weist die Vorrichtung vorzugsweise einen in das Innere der aufgerichteten Steige einfahrbaren, nach außen gegen die Lasche drückbaren Stempel und von außen gegen die Eckbereiche anliegende Gegenstempel auf. Zumindest einer der Gegenstempel ist dabei vorzugsweise mit einer Hefteinrichtung zur Verbindung der betreffenden Seitenwand mit der Holzstütze versehen.In order to carry out the pressure provided for the adhesive connection, the device preferably has a stamp which can be moved into the interior of the erected crate and which can be pressed outward against the tab, and from the outside against the corner regions. At least one of the counter-punches is preferably provided with a stapling device for connecting the relevant side wall to the wooden support.

Die Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The invention will be explained below with reference to an embodiment shown in the drawing.

Es zeigen:

  • Figur 1: eine aufgerichtete Pappsteige mit dreieckigen Aufnahmekammern für Holzstützen und mit den Holzstützen fluchtenden Zuführungskanälen;
  • Figur 2: einen in die Steige nach dem Einbringen der Holzstützen einführbaren Andruckstempel;
  • Figur 3: eine Draufsicht auf die Ecksituation aus Figur 2.
Show it:
  • FIG. 1: an erected cardboard tray with triangular receiving chambers for wooden supports and feed channels aligned with the wooden supports;
  • FIG. 2: a pressure stamp which can be inserted into the crate after the wooden supports have been introduced;
  • FIG. 3: a top view of the corner situation from FIG. 2.

Figur 1 läßt eine aufgerichtete, doppelwandige Steige erkennen, die aus einem Boden 1, zwei Längsseitenwänden 2 und zwei Stirnwänden 3 besteht. Von einer Lage der Stirnwände 3 ist jeweils eine Lasche 4 diagonal über die zugehörigen Ecken gebogen und liegt an der benachbarten Längsseitenwand 2 an. Zusammen mit der Längsseitenwand 2 und der Stirnwand 3 - jeweils im Eckbereich - bildet die Lasche 4 eine nach oben offene Aufnahmekammer 5 für eine dreieckige Holzstütze 6.Figure 1 shows an erected, double-walled tray, which consists of a bottom 1, two longitudinal side walls 2 and two end walls 3. One tab 4 is bent diagonally from one position of the end walls 3 over the associated corners and bears against the adjacent longitudinal side wall 2. Together with the longitudinal side wall 2 and the end wall 3 - each in the corner area - the tab 4 forms an upwardly open receiving chamber 5 for a triangular wooden support 6.

Um die vier Holzstützen 6 maschinell in die oben offenen Aufnahmekammern 5 einführen zu können, ist oberhalb der Aufnahmekammern 5 jeweils ein dreieckiger Zuführungsschacht 7 angeordnet, durch den die Holzstützen 6 taktweise hindurchgeführt werden. Die Schächte 7 weisen an ihren unteren, zu den Aufnahmekammern 5 zeigenden Enden nach innen abgebogene, gewölbte Laschen 8 auf, die aus elastischem Material, beispielsweise Blech, bestehen.In order to be able to mechanically insert the four wooden supports 6 into the receiving chambers 5 open at the top, a triangular feed shaft 7 is arranged above the receiving chambers 5, through which the wooden supports 6 are passed in cycles. The shafts 7 have bent at their lower, to the receiving chambers 5 ends inwardly, ge arched tabs 8, which consist of elastic material, such as sheet metal.

Die Zuführungskanäle 7 mit den Laschen 8 ermöglichen das Einführen der Holzstützen 6 in die Aufnahmekammern 5, in dem der Zuführungskanal 7 mit den nach innen gebogenen Laschen in die zugehörige Aufnahmekammer 5 abgesenkt wird. Durch eine nachfolgende Holzstütze wird die in den Zuführungsschacht 7 eingeführte Holzstütze nach unten gedrückt, wobei sie die Laschen 8 nach außen verdrängt. Dadurch drücken die Laschen gegen die Wände der Aufnahmekammer 5 und insbesondere gegen die Lasche 4 der Aufnahmekammer 5, die nur aufgrund der elastischen Rückstellkraft des Pappmaterials an der Längsseitenwand 2 anliegt und daher durch die Laschen 8 in das Innere der Steige gebogen werden kann. Nach dem Einführen der Holzstütze 6 fährt der Zuführungsschacht 7 aus der Aufnahmekammer 5 heraus.The feed channels 7 with the tabs 8 enable the wooden supports 6 to be introduced into the receiving chambers 5 by lowering the feed channel 7 with the tabs bent inwards into the associated receiving chamber 5. A subsequent wooden support pushes the wooden support inserted into the feed chute 7, displacing the tabs 8 to the outside. As a result, the tabs press against the walls of the receiving chamber 5 and in particular against the tab 4 of the receiving chamber 5, which only rests against the longitudinal side wall 2 due to the elastic restoring force of the cardboard material and can therefore be bent through the tabs 8 into the interior of the crate. After the wooden support 6 has been inserted, the feed shaft 7 moves out of the receiving chamber 5.

Vor dem Einführen der Holzstütze 6 in die Aufnahmekammer 5 ist in diese ein mit Leimdüsen versehener Stempel eingefahren und hat auf die Innenseiten der Wände der Aufnahmekammer 5 Leim aufgespritzt. Nach dem Einführen der Holzstützen 6 in die mit Leim versehene Aufnahmekammer 5 fährt in den Eckbereich der Steige 1 ein Druckstempel 9 ein, dessen Form der Kontur des durch die Innenwandungen der Längsseitenwand 2, der Stirnwand 3 und der Lasche 4 gebildeten Eckbereich entspricht. Gegen die Außenseiten der Längsseitenwand 2 und der Stirnwand 3 fahren (nicht dargestellte) Gegenhalter, woraufhin der Stempel 9 gegen die Lasche 4 drückt, was in Figur 3 durch den Pfeil A dargestellt ist.Before the wooden support 6 is inserted into the receiving chamber 5, a stamp provided with glue nozzles is inserted therein and 5 glue is sprayed onto the inside of the walls of the receiving chamber. After inserting the wooden supports 6 into the receiving chamber 5 provided with glue, a pressure stamp 9 moves into the corner region of the crate 1, the shape of which corresponds to the contour of the corner region formed by the inner walls of the longitudinal side wall 2, the end wall 3 and the tab 4. Counterholders (not shown) move against the outer sides of the longitudinal side wall 2 and the end wall 3, whereupon the stamp 9 presses against the tab 4, which is shown in FIG. 3 by the arrow A.

Durch einen an einem der Gegenhalter angebrachten Tacker werden in Figur 1 erkennbare Krampen 10 durch die Längsseitenwand 2 hindurch in die Holzstützen 6 eingeschossen. Die Krampen 10 nehmen einen wesentlichen Teil des auf die Längsseitenwände 2 ausgeübten Innendrucks durch in die Steige eingefüllte Ware auf. Dieser Druck muß daher nicht nur durch die Verklebung gehalten werden.By a stapler attached to one of the counterholders, staples 10 recognizable in FIG. 1 are shot through the longitudinal side wall 2 into the wooden supports 6. The Krampen 10 take up a substantial part of the internal pressure exerted on the longitudinal side walls 2 by goods filled into the crate. This pressure must therefore not only be kept by the gluing.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung ermöglichen erstmals eine maschinelle Fertigung von Pappsteigen mit Holzstützen in der für eine rationelle Fertigung erforderlichen Geschwindigkeit.The method and the device according to the invention make it possible for the first time to machine cardboard trays with wooden supports at the speed required for efficient production.
