Description

Die Erfindung bezieht sich auf eine Stapelbildevorrichtung zum Stapeln von flachen Werkstücken, die aus einer Bahn aus einem Verpackungsmaterial durch Stanzung hergestellt sind.The invention relates to a stack forming apparatus for stacking flat workpieces made from a sheet of packaging material by punching.

Die Werkstücke werden aus den bekannten Verpackungsmaterialien hergestellt, vorzugsweise jedoch aus Kunststofffolien. Es kommen jedoch auch als Materialien noch Papier oder Karton in Frage. Es ist im Verpackungswesen allgemein bekannt, dass Werkstücke aus Kunststofffolien schwieriger zu handhaben sind, als Werkstücke aus Papier oder Karton. Dies ist auf die wesentlich größere Flexibilität der Kunststofffolien zurückzuführen. Darüber hinaus sind die Dicken von Kunststofffolien deutlich geringer als die Dicken von Papier oder Karton.The workpieces are made of the known packaging materials, but preferably of plastic films. However, paper or paperboard can also be considered as materials. It is well known in the packaging arts that plastic film workpieces are more difficult to handle than workpieces made of paper or cardboard. This is due to the much greater flexibility of the plastic films. In addition, the thicknesses of plastic films are significantly lower than the thicknesses of paper or cardboard.

Die Bildung von Stapeln ist notwendig, da üblicherweise die Werkstücke zu Formteilen weiterverarbeitet werden. Zum Transport und zur Zwischenlagerung der Werkstücke ist es erforderlich, dass diese kantengerade übereinander gestapelt werden, d.h., die Kanten der einzelnen Seiten sollen in vertikaler Richtung eine möglichst ebene Fläche bilden. Zum Transport der in Rede stehenden Werkstücke werden im Verpackungswesen Saugbandförderer verwendet Üblicherweise werden diese Saugbandförderer kontinuierlich angetrieben. Die einzelnen Bänder sind gelocht und werden über einen mit Vakuum beaufschlagten Saugkasten gezogen. Durch die Einwirkung des Vakuums auf die Werkstücke werden diese synchron mitgenommen.The formation of stacks is necessary because usually the workpieces are processed into shaped parts. For transport and intermediate storage of the workpieces, it is necessary that these edges are just stacked one above the other, ie, the edges of the individual pages should form a flat surface as possible in the vertical direction. For transporting the workpieces in question Saugbandförderer be used in packaging usually these Saugbandförderer be driven continuously. The individual bands are perforated and are over with a vacuum pulled suction box pulled. By the action of the vacuum on the workpieces they are taken synchronously.

Die gebildeten Stapel werden während der Stapelbildung nicht verfahren, sondern durch die Zufuhr der Werkstücke wird die Höhe vergrößert. Wird eine gewisse Höhe erreicht, muss der Stapel entnommen werden und beispielsweise in ein Packmittel wie z.B. einen Karton abgesetzt werden.The stacks formed are not moved during stacking, but by the supply of workpieces, the height is increased. When a certain height is reached, the stack must be removed and, for example, placed in a package such as e.g. a carton be dropped off.

Der Erfindung liegt die Aufgabe zugrunde, eine Stapelbildevorrichtung der eingangs näher beschriebenen Art so zu gestalten, dass kantengerade Stapel gebildet werden, und dass die Anzahl der gebildeten Stapel pro Zeiteinheit relativ hoch ist, da die zu stapelnden Werkstücke in äußerst großen Stückzahlen benötigt werden, da daraus Massenprodukte hergestellt werden.The invention has for its object to make a stack forming device of the type described in more detail so that straight-edge stacks are formed, and that the number of stacks formed per unit time is relatively high, since the workpieces to be stacked are required in extremely large numbers, as From this, mass products can be produced.

Die gestellte Aufgabe wird durch mindestens einen Saugbandförderer in Form eines Horizontalförderers gelöst, dem ein Saugkasten zugeordnet ist, der mittels eines Antriebs oszillierend horizontal verfahrbar ist, und dass die Werkstücke mittels eines quer zum Saugband des Saugbandförderers verfahrbaren Abdrücker in Stapelkassetten oder Stapelstationen überführbar sind.The object is achieved by at least one Saugbandförderer in the form of a horizontal conveyor, which is associated with a suction box, which is oscillating horizontally movable by means of a drive, and that the workpieces are transferred by means of a transversely movable to the suction belt of the suction belt conveyor Abdrücker in stacking cassettes or stacking stations.

Die Werkstücke werden kontinuierlich mittels des Saugbandförderers zum Abdrücker antransportiert, da dieser mit gleichbleibender Geschwindigkeit angetrieben wird. Mittels des Saugbandförderers können auch mehrere nebeneinander liegende Werkstücke transportiert werden. Jeder Abdrücker ist dann so ausgelegt, dass diese Werkstücke gleichzeitig in den Stapel überführt werden können. Der Antrieb für den Saugkasten und somit auch für den Saugbandförderer ist so ausgelegt, dass zum lagegerechten Abdrücken der Werkstücke vom Saugband der Saugkasten entgegen der Laufrichtung des Saugbandes verfahren wird. Dadurch wird die absolute Geschwindigkeit der Werkstücke zumindest verringert, sie kann jedoch auch so ausgelegt sein, dass sinngemäß die Werkstücke im Stillstand an den sich bildenden Stapel übergeben werden. Besonders vorteilhaft ist, dass durch diese Auslegung es zu keiner Relativbewegung zwischen dem Saugbandförderer und den Werkstücken kommt.The workpieces are continuously conveyed by means of the suction belt conveyor to the ejector, since it is driven at a constant speed. By means of the suction belt conveyor also several adjacent workpieces can be transported. Each presser is then designed so that these workpieces can be transferred to the stack at the same time. The drive for the suction box and thus also for the suction belt conveyor is designed so that for correct position of the workpieces from the suction belt, the suction box is moved counter to the direction of the suction belt. As a result, the absolute speed of the workpieces is at least reduced, but they can also be designed so that mutatis mutandis the workpieces are transferred to the forming stack at a standstill. It is particularly advantageous that due to this design there is no relative movement between the suction belt conveyor and the workpieces.

In weiterer Ausgestaltung ist vorgesehen, dass mehrere Saugbandförderer und Saugkästen hintereinander geschaltet sind, und dass jedem Saugbandförderer mehrere säulenförmige Stapelkassetten zugeordnet sind, die in Laufrichtung des Saugbandförderers und quer zum Saugbandförderer angeordnet sind. Diese Stapelkassetten können dann gleichzeitig zur Bildung einer entsprechenden Stückzahl von Stapeln verwendet werden. In bevorzugter Ausführung liegen zwei Saugbandförderer und zwei Saugkästen hintereinander, die jedoch im ständigen Wechsel benutzt werden, um die Stapelkassetten zu füllen. Während die gefüllten Stapelkassetten entnommen werden, werden die anderen Stapelkassetten gefüllt, so dass ein kontinuierlicher Betrieb gewährleistet ist. Dabei ist zumindest ein Saugbandförderer so ausgelegt, dass eine Weichenfunktion gegeben ist, um die antransportierten Werkstücke im ständigen Wechsel den beiden Saugbandförderem zuzuführen.In a further embodiment, it is provided that several Saugbandförderer and suction boxes are connected in series, and that each Saugbandförderer associated with a plurality of columnar stacking cassettes, which are arranged in the running direction of the suction belt conveyor and transversely to Saugbandförderer. These stacking cassettes can then simultaneously to form a corresponding Number of stacks are used. In a preferred embodiment, two Saugbandförderer and two suction boxes are behind each other, but used in constant change to fill the stacking cassettes. As the filled stack cassettes are removed, the other stack cassettes are filled to ensure continuous operation. In this case, at least one suction belt conveyor is designed so that a switch function is given to supply the transported workpieces in constant change the two Saugbandförderem.

In einer ersten Ausführungsform in Hinsicht auf die Stapelbildung und die Anordnung der Stapelkassetten, ist vorgesehen, dass die Stapelkassetten oberhalb jedes Saugbandförderers angeordnet sind, und dass die eingebrachten Werkstücke mittels flexibler Rückhalteelemente abstützbar sind, vorzugsweise durch mehrere Borstenbüschel, die in Winkelabständen und in gleicher Ebene zueinander angeordnet sind und dass jeder Abdrücker dem Obertrum des Saugbandförderers zugeordnet ist.In a first embodiment with regard to the stack formation and the arrangement of the stacking cassettes, it is provided that the stacking cassettes are arranged above each suction belt conveyor, and that the introduced workpieces can be supported by means of flexible retaining elements, preferably by a plurality of bristle tufts, which are arranged at angular intervals and in the same plane are arranged to each other and that each Abdrücker is assigned to the upper strand of the suction belt conveyor.

Bei dieser Ausführung erfolgt die Stapelbildung von unten her, da durch die laufend zugeführten Werkstücke der Abstand des obersten Werkstückes zum Saugband sich ständig vergrößert. Bei der zuvor beschriebenen Ausführung ist dann auch noch vorgesehen, dass das die Werkstücke zu den Stapelkassetten transportierende Obertrum des Saugbandförderers entgegen der Antransportrichtung der Werkstücke zum Saugbandförderer verläuft, und dass der Saugkasten zur Abgabe der Werkstücke entgegen der Laufrichtung des Obertrums verfahrbar ist.In this embodiment, the stacking is carried out from below, as constantly increased by the continuously supplied workpieces, the distance of the uppermost workpiece to the suction belt. In the embodiment described above, it is then also provided that the upper strand of the suction belt conveyor transporting the workpieces to the stacking cassettes runs counter to the transporting direction of the workpieces to the suction belt conveyor, and that the suction box for delivering the workpieces can be moved counter to the running direction of the upper run.

Gemäß einer zweiten Ausführung hinsichtlich der Stapelbildung ist vorgesehen, dass jeder Abdrücker dem Untertrum des Saugbandförderers zugeordnet ist, und die Stapelkassetten oder ein sonstiges Packmittel unterhalb des Saugbandförderers angeordnet ist.According to a second embodiment with regard to stack formation, it is provided that each ejector is assigned to the lower strand of the suction belt conveyor, and the stacking cassettes or other packaging material is arranged below the suction belt conveyor.

Während bei der ersten Ausführung die Werkstücke zunächst dem Untertrum des Saugbandförderers zugeführt werden, werden bei dieser Ausführung die Werkstücke dem Obertrum zugeführt. Bei diesen beiden Ausführungen werden die Saugbandförderer und die Saugkästen spiegelbildlich angeordnet. Die Stapelbildung erfolgt dann durch Zuführung der Werkstücke von oben, so dass sich der Abstand des untersten Werkstückes zum Saugbandförderer ständig vergrößert.While in the first embodiment, the workpieces are first fed to the lower run of Saugbandförderers, the workpieces are supplied to the upper run in this embodiment. In these two versions, the Saugbandförderer and the suction boxes are arranged in mirror image. The stacking is then carried out by supplying the workpieces from above, so that the distance between the bottom workpiece continuously increases to Saugbandförderer.

Sofern bei der zweiten Ausführung die Stapel in geeignete Packmittel abgelegt werden, beispielsweise in Kartons, ist noch vorgesehen, dass den Stapelbildemitteln ein Querförderer zugeordnet ist, um die gefüllten Packmittel abzuführen. Diese Querförderer werden dann taktmäßig angetrieben.If in the second embodiment, the stacks are stored in suitable packaging, for example in boxes, it is also provided that the stack image means is associated with a cross conveyor to remove the filled packaging. These cross conveyors are then driven cyclically.

Bei beiden Ausführungen werden die Transportrichtungen der zum Saugbandförderer antransportierten Werkstücke vor der Abgabe für die Stapelbildung umgekehrt, d.h. um 180° geändert. Damit die Werkstücke daher nur relativ geringfügig gekrümmt werden, ist vorgesehen, dass jeder Saugbandförderer aus einer dem Abstand des Obertrums zum Untertrum des Saugbandes im Durchmesser entsprechenden Wendetrommel und zwei beabstandeten achsparallelen Umlenkrolle besteht, wobei jede Wendetrommel in dem dem Übernahmebereich für die Werkstücke gegenüberliegenden Bereich gelagert ist.In both embodiments, the transport directions of the workpieces transported to the suction belt conveyor are reversed prior to delivery for stacking, i. changed by 180 °. Thus, the workpieces are therefore only relatively slightly curved, it is provided that each Saugbandförderer consists of a the distance of the upper run to the lower run of the suction belt in diameter corresponding turning drum and two spaced paraxial guide roller, each beater mounted in the receiving area for the workpieces opposite area is.

Als Antrieb für den Saugkasten kommt ein mechanischer Antrieb bevorzugt in Betracht. Derartige Antriebe sind beispielsweise Kurbeltriebe, Kurvenscheibenantriebe oder ein Linearantrieb. Als Linearantriebe werden bevorzugt sogenannte Elektrozylinder eingesetzt.As a drive for the suction box, a mechanical drive is preferably considered. Such drives are, for example, crank mechanisms, cam drives or a linear drive. As linear drives so-called electric cylinders are preferably used.

Die erfindungsgemäße Stapelbildevorrichtung könnte auch als Abtafter bezeichnet werden.The stack forming device according to the invention could also be referred to as a Abtafter.

Anhand der beiliegenden Zeichnungen wird die Erfindung noch näher erläutert.Reference to the accompanying drawings, the invention will be explained in more detail.

Zur Bildung der nicht dargestellten Werkstücke wird eine Bahn aus einem Verpackungsmaterial von einer ebenfalls nicht dargestellten Rolle abgezogen. Diese Bahn durchläuft eine in der Verpackungstechnik bekannte Rotationsstanze 10, 11, in der die Werkstücke konturengerecht geschnitten bzw. gestanzt werden. Dabei können mehrere gleiche Werkstücke nebeneinander liegen. Die Bahn wird von einem Vorzug kontinuierlich vorgezogen, die aus zwei Walzen besteht, die gegeneinander einstellbar sind. Die Rotationsstanze ist durch eine Einstellvorrichtung 12 einstellbar. Die Werkstücke werden dann mit einem Austrageband 25 (Figur 3) weitertransportiert und während dieses Transportes werden in einer Trennstation 13 die Werkstücke von der Bahn getrennt. Dieser Vorgang wird auch als Entgitterung bezeichnet. Die als Abfall anzusehende Restbahn wird dann über Umlenkwalzen einer Absaugeinrichtung 21 zugeführt, in der sie beispielsweise geschreddert werden.To form the workpieces, not shown, a web is drawn from a packaging material from a roll, also not shown. This web passes through a known in packaging rotary die 10, 11, in which the workpieces are contour cut or punched. Several identical workpieces can lie next to each other. The web is continuously advanced by a virtue consisting of two rolls which are adjustable against each other. The rotary die is adjustable by an adjusting device 12. The workpieces are then removed with a discharge belt 25 (FIG. FIG. 3 ) transported further and during this transport, the workpieces are separated from the web in a separation station 13. This process is also called de-littering. The residual web to be regarded as waste is then fed via deflecting rollers to a suction device 21 in which they are shredded, for example.

Die Werkstücke werden dann dem Saugbandförderer 15 zugeführt, der, in Antransportrichtung der Werkstücke gesehen, hinteren Bereich eine Wendetrommel aufweist. Der Durchmesser dieser Wendetrommel entspricht dem Abstand des Obertrums zum Untertrum des Saugbandförderers 15. Das Saugband wird dann über einlaufseitige Umlenkwalzen 16 geführt.The workpieces are then fed to the suction belt conveyor 15 which, viewed in the direction of transport of the workpieces, has a turning drum at the rear. The diameter of this turning drum corresponds to the distance of the upper run to the lower run of the suction belt conveyor 15. The suction belt is then guided over inlet-side guide rollers 16.

Wie die Figur 1 zeigt, ist die dargestellte Ausführung mit zwei hintereinander angeordneten Saugbandförderem 15 ausgestattet. Diese werden von einem gemeinsamen Saugband 14 bedient, welches gleichzeitig eine Weichenfunktion hat, um die Werkstücke nach Bildung einer Gruppe von Stapeln dem anderen Saugbandförderer 15 zuzuführen. Wie die Figur 1 zeigt, ist dem Obertrum des Saugbandförderers 15 jeweils ein Abdrücker 20 zugeordnet, um die Werkstücke in Stapelkassetten 19 einzubringen. Dabei sind mehrere Reihen von Stapelkassetten 19 vorgesehen. Aus der Figur 2 ergibt sich, dass den einzelnen Stapelkassetten 19 flexible Rückhalteelemente 22, beispielsweise in Form von Borstenbüscheln zugeordnet sind, die teilweise den unteren Bereich jeder Stapelkassette 19 untergreifen.As the FIG. 1 shows, the illustrated embodiment with two successively arranged Saugbandförderem 15 is equipped. These are operated by a common suction belt 14, which at the same time has a switch function to supply the workpieces to the other Saugbandförderer 15 after forming a group of stacks. As the FIG. 1 shows, the upper run of Saugbandförderers 15 is assigned a respective Abdrücker 20 to bring the workpieces in stacking cassettes 19. Several rows of stacking cassettes 19 are provided. From the FIG. 2 shows that the individual stacking cassettes 19 are associated with flexible retaining elements 22, for example in the form of bristle tufts, which partially engage under the lower region of each stacking cassette 19.

Jeder Saugkasten bzw. jeder Saugbandförderer 15 ist im dargestellten Ausführungsbeispiel mittels eines Kurbeltriebes 17 in horizontaler Ebene oszillierend antreibbar. Diese Kurbeltriebe 17 sind so ausgelegt, dass der Saugkasten entgegen der Laufrichtung des Obertrums verfahren wird, sobald die Werkstücke unterhalb der Stapelkassetten 19 liegen. Durch Betätigung des Abdrückers 20 werden sie dann vom Obertrum des Saugbandförderers 15 getrennt und in die Stapelkassetten 19 gedrückt.Each suction box or each Saugbandförderer 15 is driven in the illustrated embodiment by means of a crank mechanism 17 in a horizontal plane oscillating. These crank mechanisms 17 are designed so that the suction box is moved counter to the direction of the upper run as soon as the workpieces lie below the stack cassettes 19. By actuation of the breaker 20, they are then separated from the upper run of the suction belt conveyor 15 and pressed into the stacking cassettes 19.

In der Figur 1 ist noch ein Riemen 18, vorzugsweise ein Zahnriemen angedeutet, der von einer Antriebswalze 23 angetrieben wird und die Kurbelscheibe des Kurbeltriebes 17 antreibt. Die Figur 2 zeigt noch den Rahmen 24 der Stapelbildeeinrichtung und die borstenartigen Rückhalteelemente 22.In the FIG. 1 is still a belt 18, preferably a toothed belt indicated, which is driven by a drive roller 23 and the crank pulley of the crank mechanism 17 drives. The FIG. 2 shows still the frame 24 of the stack forming device and the bristle-like retaining elements 22nd

Die Ausführung nach der Figur 3 zeigt eine spiegelbildliche Ausführung der beiden Saugbandförderer 15 und der Saugkästen, die unterhalb des Saugbandes 14 zum Antransport der Werkstücke angeordnet sind. Bei dieser Ausführung sind die Abdrücker 20 dem Untertrum des Saugbandförderers 15 zugeordnet. Auch die Saugkästen werden mittels Kurbeltrieben 17 angetrieben. Die Werkstücke können wiederum mittels der Abdrücker 20 in Stapelkassetten eingebracht werden, können jedoch auch in Stapelstationen 28 abgelegt werden, um beispielsweise Kartons zu befüllen. In diesem Falle ist die Stapelbildevorrichtung noch mit oszillierend verfahrbaren Kartonhaltern 26 versehen. Bei einer solchen Ausführung ist die Stapelstation 28 noch jeweils mit einem Querförderer 27 versehen, um die gefüllten Behältnisse b zw. Kartons abzutransportieren.The execution after the FIG. 3 shows a mirror-image embodiment of the two Saugbandförderer 15 and the suction boxes, which are arranged below the suction belt 14 for transporting the workpieces. In this embodiment, the ejector 20 are assigned to the lower run of the suction belt conveyor 15. The suction boxes are driven by means of crank drives 17. The workpieces can in turn be introduced by means of the ejector 20 in stack cassettes, but can also be stored in stacking stations 28, for example, to fill boxes. In this case, the stack forming device is still provided with oscillating movable cardboard holders 26. In such an embodiment, the stacking station 28 is still provided in each case with a transverse conveyor 27 to transport the filled containers b zw. Cartons.

In der Figur 3 ist noch das Austragesaugband 25 dargestellt, welches der Trennstation 13 zugeordnet ist und mit dem die Werkstücke dem Saugband 14 zugeführt werden, um sie dann dem Saugbandförderer 15 zuzuführen.In the FIG. 3 is still the Austragesaugband 25 shown, which is associated with the separation station 13 and with which the workpieces are fed to the suction belt 14, to then supply them to the Saugbandförderer 15.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Wesentlich ist, dass zur Übergabe der einzelnen neben- und hintereinander liegenden Werkstücke mittels eines Abdrückers 20 an Stapelkassetten 19 oder sonstige Behältnisse einer Stapelstation 28 der dem Saugbandförderer 15 zugeordnete Saugkasten entgegen der Laufrichtung der Werkstücke verfahren wird, so dass die Übergabe bei reduzierter Geschwindigkeit der Werkstücke oder sinngemäß im Stillstand erfolgt. Dabei soll eine Relativbewegung zu den Werkstücken ausgeschlossen werden.The invention is not limited to the illustrated embodiments. It is essential that for transferring the individual adjacent and successive workpieces by means of a Abdrückers 20 to stacking cassettes 19 or other containers of a stacking station 28 of the Saugbandförderer 15 associated suction box is moved counter to the direction of workpieces, so that the transfer at reduced speed of the workpieces or mutatis mutandis takes place at a standstill. In this case, a relative movement to the workpieces should be excluded.
