Description

Die Erfindung betrifft eine Vorrichtung zum Überführen von kontinuierlich angeförderten flachen, an ihren in Förderrichtung gegenüberliegenden Enden ungleich dicken Gegenständen, insbesondere von flachliegenden Faltbodenschachteln, zu einer Packeinrichtung gemäß dem Oberbegriff des Patentanspruchs 1 und eine Einrichtung zum Ablegen von flachen Gegenständen, insbesondere von Faltbodenschachteln gemäß dem Oberbegriff des Patentanspruchs 6.The invention relates to a device for transferring continuously conveyed flat, at their ends opposite in the conveying direction of unevenly thick objects, in particular flat-lying folding bottom boxes, to a packing device according to the preamble of claim 1 and a device for storing flat objects, in particular folding bottom boxes according to the Preamble of claim 6.

Beim Stapeln von flachen Gegenständen mit an gegenüberliegenden Enden ungleicher Dicke ist es bekannt, auf dem Transport zur Stapelstelle eine Anzahl - etwa die Hälfte - der Gegenstände um 180° zu wenden, um einen regelmäßigen Stapel zu erzielen.When stacking flat objects with opposite thicknesses at opposite ends, it is known to turn a number - about half - of the objects by 180 ° during transport to the stacking point in order to achieve a regular stack.

In der DE-OS 20 09 373 ist eine gattungsgemäße Vorrichtung zum Stapeln von Zeitungen beschrieben, bei der die auf einem Transportband angeförderten Zeitungen von einer Verteilstation auf zwei Fördereinrichtungen aufgeteilt werden, die jeweils zu den gegenüberliegenden Seiten einer Empfangsstation führen, wo die Zeitungen gestapelt und gebündelt werden. Während eine Fördereinrichtung die Zeitungen ohne zu wenden zu der in Transportrichtung vorne liegenden Seite der Empfangsstation fördert, führt die zweite Fördereinrichtung unterhalb der Empfangsstation hierdurch und wendet um 180° zu der hinteren Seite der Empfangsstation.DE-OS 20 09 373 describes a generic device for stacking newspapers, in which the newspapers conveyed on a conveyor belt are divided by a distribution station into two conveyors, each of which leads to the opposite sides of a receiving station, where the newspapers are stacked and be bundled. While a conveying device conveys the newspapers to the front side of the receiving station lying forward in the transport direction, the second conveying device leads below the receiving station and turns through 180 ° to the rear side of the receiving station.

Aus dem DE-GM 84 37 318 ist eine Vorrichtung zum Bilden eines regelmäßigen Stapels aus Faltschachteln bekannt, bei der ebenfalls der zugeförderte Strom aus Faltschachteln zu zwei Fördereinrichtungen aufgeteilt wird. Dort führt eine Fördereinrichtung oberhalb der Stapelstelle in einem Bogen von 180° zu der Hinterseite der Stapelstelle, wo sie die Faltschachteln unten in einen Stapelschacht ablegt.From DE-GM 84 37 318 a device for forming a regular stack of folding boxes is known, in which the supplied flow of folding boxes is also divided into two conveying devices. There, a conveyor device leads above the stacking point in an arc of 180 ° to the rear of the stacking point, where it places the folding boxes below in a stacking shaft.

Nachteilig an diesen bekannten Vorrichtungen ist, daß ein kontinuierliches Einpacken der Gegenstände in senkrechter Lage in Kartons, wie es bei Faltschachteln üblich ist, nicht möglich ist.A disadvantage of these known devices is that continuous packing of the objects in a vertical position in boxes, as is customary with folding boxes, is not possible.

Darüber hinaus treten beim Einpacken flacher, gefalteter Gegenstände, die zum Öffnen neigen - z.B. flachliegende Faltbodenschachteln - besondere Probleme auf:In addition, when packing flat, folded objects that tend to open - e.g. lying flat bottom boxes - special problems on:

Erfahrungsgemäß dürfen die zum Öffnen neigenden Faltbodenschachteln nicht über größere Strecken frei fallengelassen werden - wie die Zeitungen in der DE-OS 20 09 373 - und können aufgrund der übereinandergefalteten Bodenlappen und Seitenteile auch nicht problemlos mit Deckel oder Boden voran übereinandergeschoben werden.Experience has shown that the folding bottom boxes, which tend to open, must not be dropped freely over long distances - like the newspapers in DE-OS 20 09 373 - and, because of the folded-over bottom flaps and side parts, cannot be easily pushed over one another with the lid or bottom first.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, mit der auch zum Öffnen neigende, gefaltete Gegenstände, insbesondere Faltbodenschachteln, so zu einer nachfolgenden Packeinrichtung geführt werden, daß sie dort auf einfache Weise in senkrechter Lage in Umkartons eingepackt werden können.The invention has for its object to provide a generic device with which open, folded objects, especially folding bottom boxes, are guided to a subsequent packing device so that they can be easily packed in a vertical position in cartons.

Eine weitere Aufgabe liegt darin, eine konstruktiv einfache Einrichtung zu schaffen, mit der es möglich ist, flachliegende Faltschachteln, die zum Durchhängen neigen, von zwei gegenüberliegenden Seiten aufeinanderfolgend bei geringer Fallhöhe übereinander abzulegen.Another object is to provide a structurally simple device with which it is possible to lay flat-lying folding boxes, which tend to sag, in succession from two opposite sides at a low drop height.

Die erste Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst. Das Sammeln auf einem querfördernden Transportband ermöglicht den Einsatz von automatischen bzw. halbautomatischen Packeinrichtungen zum Einbringen der Gegenstände in senkrechter Lage in Umkartons. Geeignete Packeinrichtungen sind z.B. in der DE-PS 22 61 416 oder in der DE-OS 38 01 279 beschrieben.The first object is achieved with the features of patent claim 1. Collecting on a cross-conveying conveyor belt enables the use of automatic or semi-automatic packing devices for placing the objects in a vertical position in outer cartons. Suitable packing facilities are e.g. described in DE-PS 22 61 416 or in DE-OS 38 01 279.

Patentanspruch 6 löst die zweite Aufgabe.Claim 6 solves the second problem.

Die Unteransprüche enthalten bevorzugte Ausführungsformen der Erfindung. Während das Merkmal des Anspruchs 2 Probleme beim Sammeln aufgrund einer zu großen Fallhöhe vermeidet, befindet sich das abfördernde Transportband bei der Ausführungsform nach Anspruch 3 in einer zum manuellen Einbringen in Umkartons optimalen Höhe.The subclaims contain preferred embodiments of the invention. While the feature of claim 2 avoids problems with collecting due to a too high drop height, the conveying conveyor belt in the embodiment according to claim 3 is at an optimal height for manual insertion into outer cartons.

Das Merkmal des Anspruchs 4 ermöglicht konstruktiv einfach die Aufteilung auf die beiden Förderstrecken zu gleichen Anteilen bei gleicher Fördergeschwindigkeit zum Erzeugen eines regelmäßigen Schuppenstromes auf dem abfördernden Transportband. Patentanspruch 5 enthält eine platzsparende Konstruktion einer Vorrichtung nach Anspruch 4.The feature of claim 4 allows structurally simple division of the two conveyor lines in equal proportions at the same conveying speed to produce a regular stream of shingles on the conveying belt. Claim 5 contains a space-saving construction of a device according to claim 4.

Die Unteransprüche 7 bis 9 enthalten konstruktiv vorteilhafte Ausgestaltungen einer Einrichtung nach Anspruch 6.The sub-claims 7 to 9 contain constructively advantageous configurations of a device according to claim 6.

Die Zeichnungen dienen zur Erläuterung der Erfindung anhand eines vereinfacht dargestellten Ausführungsbeispiels. Das Ausführungsbeispiel dient zum Überführen von flachliegenden Faltbodenschachteln, die in einer vorgeschalteten Klebemaschine aus Zuschnitten hergestellt wurden, zu einer Packeinrichtung, wo sie in Umkartons eingebracht werden.

The drawings serve to explain the invention with reference to an embodiment shown in simplified form. The exemplary embodiment serves for transferring flat-lying folding-bottom boxes, which were produced from blanks in an upstream gluing machine, to a packing device, where they are placed in outer cartons.

Von einer nicht dargestellten Faltschachtel-Klebemaschine führt ein Abtransportband 1 zu einer Übergabeeinrichtung 2 zum vereinzelten Zuführen von Faltschachteln zu zwei getrennten Fördereinrichtungen 3, 4, die jeweils aus einem umlaufenden Ober- und Unterriemen bestehen. Zwischen der Übergabeeinrichtung 2 und den Fördereinrichtungen 3, 4 befindet sich eine steuerbare Bänderschleuse 5, mit der die Faltschachteln wechselweise den beiden Fördereinrichtungen 3, 4 zugeführt werden können. Eine derartige Bänderschleuse 5 ist in der DE-GM 87 17 500 beschrieben.A conveyor belt 1 leads from a folding box gluing machine (not shown) to a transfer device 2 for the individual feeding of folding boxes to two separate conveying devices 3, 4, each consisting of a rotating upper and lower belt. Between the transfer device 2 and the conveying devices 3, 4 there is a controllable belt lock 5 with which the folding boxes can alternately be fed to the two conveying devices 3, 4. Such a belt lock 5 is described in DE-GM 87 17 500.

Beide Fördereinrichtungen 3, 4 verlaufen in einer senkrechten Ebene und enden jeweils an gegenüberliegenden Seiten und in geringer Höhe oberhalb eines waagerechten, querabfördernden Transportbandes 6, das etwa in Höhe des Abtransportbandes 1 angeordnet ist und zu einer nicht dargestellten Packeinrichtung führt. Die untere Fördereinrichtung 4 führt unterhalb des Transportbandes 6 hindurch und wird anschließend um 180° zurückgelenkt und endet in kurzem Abstand oberhalb des Transportbandes 6. Die obere Fördereinrichtung 3 führt, ohne daß die Faltschachteln gewendet werden, direkt zum Querband 6 und endet etwa in gleicher Höhe wie die Fördereinrichtung 4 an der gegenüberliegenden Seite des Transportbandes 6. Damit die Länge des Förderweges der beiden Fördereinrichtungen 3, 4 übereinstimmt, wird die Fördereinrichtung 3 in einer Ausgleichsschlaufe zu dem Querband 6 geführt.Both conveyors 3, 4 run in a vertical plane and each end on opposite sides and at a low height above a horizontal, cross-conveying conveyor belt 6, which is arranged approximately at the level of the conveyor belt 1 and leads to a packing device, not shown. The lower conveyor 4 passes underneath the conveyor belt 6 and is then deflected back by 180 ° and ends at a short distance above the conveyor belt 6. The upper conveyor 3 leads directly to the transverse belt 6 without the folding boxes being turned and ends at approximately the same height like the conveyor 4 on the opposite side of the conveyor belt 6. So that the length of the conveyor path of the two conveyors 3, 4 matches, the conveyor 3 is guided in a compensating loop to the cross belt 6.

Das Querband 6 - ein umlaufender Bandförderer - führt zu einer nicht dargestellten Packeinrichtung, mit der die Faltschachteln in Umkartons eingebracht werden.The cross belt 6 - a revolving belt conveyor - leads to a packing device, not shown, with which the folding boxes are inserted into outer cartons.

In den Abbildungen 2 und 3 ist der Bereich des Endes der Fördereinrichtungen 3, 4 und des Querbandes 6 vergrößert dargestellt.In Figures 2 and 3, the area of the end of the conveyors 3, 4 and the cross belt 6 is shown enlarged.

Die das Ende der Fördereinrichtungen 3, 4 bildenden Umlenkrollen 7, 8 der Transportriemen 9, 10 befinden sich an den beiden Seiten mit kurzem Abstand oberhalb des Querbandes 6. Ihr Abstand voneinander ist verstellbar, so daß der sich zwischen ihnen befindliche Ablagebereich 11 auf unterschiedliche Faltschachtellängen eingestellt werden kann. Unterhalb der unteren Umlenkrollen 7.2, 8.2 sind oberhalb des Querbandes 6 zwei seitliche, ebenfalls verstellbare Anschläge 12, 13 angeordnet. Seitlich mit Abstand neben den Transportriemen 9, 10 sind parallel zu diesen etwas oberhalb der Untertrums der oberen Riemen 9.1, 10.1 am Ende jeder Fördereinrichtung 3, 4 jeweils zwei Stäbe 14,1, 14,2, bzw. 15 angeordnet, die bis in den Ablagebereich 11 reichen. Mittels dieser Stäbe 14 bzw. 15 werden die Faltschachteln 16 beim Verlassen der Fördereinrichtung 3, 4 an ihren seitlichen Rändern nach oben gedrückt in den Ablagebereich 11 geführt. Dies führt zu einer Stabilisierung in Transportrichtung, so daß das jeweils vordere Ende der Faltschachteln 16 nicht nach unten abknickt, wenn die Führung durch die Transportriemen 9 bzw. 10 endet.The deflecting rollers 7, 8 of the conveyor belts 9, 10 forming the end of the conveying devices 3, 4 are located on both sides with a short distance above the cross belt 6. Their distance from one another is adjustable, so that the storage area 11 located between them is at different folding box lengths can be adjusted. Two lateral, also adjustable stops 12, 13 are arranged below the lower deflection rollers 7.2, 8.2 above the cross belt 6. Laterally at a distance from the conveyor belts 9, 10, two rods 14, 14, 14 and 15 are arranged parallel to these, somewhat above the lower run of the upper belts 9.1, 10.1 at the end of each conveyor 3, 4 Storage area 11 are sufficient. By means of these rods 14 and 15, the folding boxes 16 are pushed upwards at their lateral edges when leaving the conveying device 3, 4 into the storage area 11. This leads to stabilization in the transport direction, so that the respective front end of the folding boxes 16 does not bend downwards when the guidance through the transport belts 9 or 10 ends.

Nach einer anderen Ausführungsform sind anstelle der Stäbe 14, 15 seitlich neben den auslaufseitigen Umlenkrollen 7 bzw. 8 senkrechte Führungsrollen zum Hochdrücken der seitlichen Ränder der Faltschachteln angeordnet. Der Umfang der Führungsrollen reicht bis etwas oberhalb der Untertrums der oberen Förderriemen 9.1. bzw. 10.1. Dies kann z.B. durch koaxial zu den auslaufseitigen Umlenkrollen 7.1. bzw. 8.1. angeordnete Führungsrollen mit etwas größerem Durchmesser erreicht werden.According to another embodiment, instead of the rods 14, 15, vertical guide rollers are arranged laterally next to the deflection rollers 7 and 8 on the outlet side, for pushing up the lateral edges of the folding boxes. The circumference of the guide rollers extends slightly above the lower run of the upper conveyor belts 9.1. or 10.1. This can be done, for example, by coaxial to the outlet-side deflection rollers 7.1. or 8.1. arranged guide rollers can be achieved with a slightly larger diameter.

Die Vorrichtung des Ausführungsbeispiels arbeitet wie folgt:The device of the embodiment works as follows:

Von der Sammel- und Presseinrichtung einer Faltbodenschachtelklebemaschine wird kontinuierlich ein Schuppenstrom von dem Abtransportband 1 zu der Übergabeeinrichtung 2 gefördert. Dabei befindet sich der gefaltete Boden der Faltbodenschachteln 16 vorne und demgemäß der Deckel hinten und oben liegend. Von dem sich vor der Übergabeeinrichtung 2 aufstauenden Schuppenstrom werden eine bestimmte Anzahl (z.B. 10) Schachteln 16 einzeln mit Abstand aufeinanderfolgend mittels der Bänderschleuse 5 zunächst einer der Fördereinrichtungen 3 oder 4 zugeführt. Nach der eingestellten Schachtelanzahl schaltet die Bänderschleuse 5 auf die jeweils andere Fördereinrichtung 3 oder 4 um. So wird auf dem querabfördernden Transportband 6 ein kontinuierlicher Schuppenstrom erzeugt. Dieser Schuppenstrom wird mittels einer nicht dargestellten Packeinrichtung in Umkartons automatisch eingebracht.A shingled stream is continuously conveyed from the conveyor belt 1 to the transfer device 2 by the collecting and pressing device of a folding-bottom box gluing machine. The folded bottom of the folding bottom boxes 16 is located at the front and, accordingly, the lid is at the rear and at the top. A certain number (e.g. 10) boxes 16 of the stream of streams accumulating in front of the transfer device 2 are first fed one by one to the conveyor devices 3 or 4 at a distance using the belt lock 5. After the set number of boxes, the belt lock 5 switches over to the other conveyor 3 or 4. A continuous stream of flakes is thus generated on the transversely conveying conveyor belt 6. This stream of flakes is automatically introduced into outer cartons by means of a packing device (not shown).

Die von der unteren Fördereinrichtung 4 auf dem Transportband 6 abgelegten Faltbodenschachteln 16 werden dabei gegenüber den mit der Fördereinrichtung 3 zugeführten Faltbodenschachteln 16 um 180° gewendet, so daß die dickere Seite mit dem Boden jeweils auf gegenüberliegenden Seiten des Transportbandes 6 abgelegt wird. Da es aufgrund des abwechselnden Ablegens von beiden Fördereinrichtungen 3, 4 nicht möglich ist, die zum Durchhängen neigenden Faltbodenschachteln 16 über die gesamte Ablagestelle 11 zu führen, werden die Faltbodenschachteln 16 beim Verlassen der Förderer 3, 4 quer zur Transportrichtung gekrümmt gehalten. Dies erfolgt mittels der Stäbe 14.1, 14.2 bzw. 15. Die Krümmung quer zur Transportrichtung stabilisiert die Faltbodenschachteln 16, die so problemlos kontinuierlich übereinander abgelegt werden können. Die Stabilisierung ist insbesondere bei den von der unteren Fördereinrichtung 4 zugeführten Faltbodenschachtel 16 erforderlich, da diese beim Verlassen der Transportriemen 10.1., 10.2 zuletzt nur an ihrem Deckel gehalten werden und zusätzlich über die oben liegenden Seitenteile der vorhergehenden Faltbodenschachteln 16 geschoben werden müssen.The folding bottom boxes 16 placed on the conveyor belt 6 by the lower conveyor 4 are turned 180 ° with respect to the folding bottom boxes 16 fed with the conveyor 3, so that the thicker side with the bottom is placed on opposite sides of the conveyor belt 6. Since it is not possible due to the alternate placement of the two conveyor devices 3, 4, the folding bottom boxes 16 which tend to sag over the entire storage location 11, the folding bottom boxes 16 are kept curved transversely to the transport direction when they leave the conveyor 3, 4. This is done by means of the rods 14.1, 14.2 and 15. The curvature transverse to the direction of transport stabilizes the folding bottom boxes 16, which can thus be continuously stacked on top of one another without any problems. Stabilization is particularly necessary in the case of the folding bottom box 16 fed by the lower conveyor device 4, since when they leave the transport belts 10.1., 10.2 they are last only held by their lid and must additionally be pushed over the side parts of the previous folding bottom boxes 16 located above.
