Description

Technisches GebietTechnical field

Die Erfindung betrifft eine Vereinzelungsvorrichtung einer Kartoniermaschine, insbesondere eines Kartonaufrichters, gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a separating device Cartoning machine, in particular a carton erector, according to the preamble of claim 1.

Stand der TechnikState of the art

Im Stand der Technik sind Kartoniermaschinen, welche aus Kartonzuschnitten Schachteln formen, in den verschiedensten Ausführungsformen bekannt. Üblicherweise werden sogenannte Kartonaufrichter verwendet, in welchen die Kartonzuschnitte aus einer horizontalen Ausgangsposition in die gewünschte Form gebogen werden. Diese Maschinen umfassen im wesentlichen ein Magazin, in welchem die Kartonzuschnitte gestapelt sind, eine Vereinzelungsvorrichtung zur Entnahme einzelner Kartonzuschnitte und ein Aufrichtewerk mit Formstössel zur Formung des Zuschnitts in die gewünschte Schachtel. Vor und nach dem Aufrichtewerk sind üblicherweise Förderer vorhanden, um den Kartonzuschnitt in das Aufrichtewerk beziehungsweise die fertige Schachtel aus diesem hinaus zu fördern.In the prior art, cartoning machines are made of Cardboard blanks Form boxes in a wide variety Embodiments known. So-called Carton erector used in which the carton blanks from a horizontal starting position in the desired shape can be bent. These machines include essentially a magazine in which the cardboard blanks are stacked, a separating device for removing individual cardboard blanks and an erecting unit with ram for shaping the cut into the desired box. Before and after the erection work Usually conveyors are available to cut the carton into the erection unit or the finished box to promote from this.

Die Kartonzuschnitte liegen entweder annähernd waagrecht oder annähernd senkrecht im Magazinstapel. Im letzteren Fall müssen sie jeweils mittels der Vereinzelungsvorrichtung um 90° in eine waagrechte Position geschwenkt werden, bevor sie dem Aufrichtewerk übergeben werden können. Da die für die Übergabe der Kartonzuschnitte vom Magazin zum Aufrichtewerk benötigte Zeit die Leistungsfähigkeit der gesamten Maschine wesentlich beeinflusst, sollte diese Umsetzung so einfach wie möglich gestaltet sein aber trotzdem eine möglichst positionsgenaue Umsetzung ermöglichen.The cardboard blanks are either approximately horizontal or approximately vertically in the magazine stack. In the latter In each case, they must use the separating device be pivoted through 90 ° into a horizontal position, before they can be handed over to the erector. As for the transfer of the cardboard blanks from the magazine the time required to perform the erection work of the entire machine, it should Implementation should be as simple as possible nevertheless enable a position as accurate as possible.

So offenbart EP-A-1'184'161 eine Maschine zum Aufrichten von Schachteln aus Kartonzuschnitten, deren Vereinzelungsvorrichtung einen rotierbaren, zweiteiligen Arm aufweist. Die Rotationsachse des Arms liegt unterhalb der Transportbahn, so dass sie nicht mit anderen Maschinenkomponenten kollidiert. Die beiden Teile des Arms sind gelenkig miteinander verbunden und mittels eines gesteuerten Antriebs gegeneinander verschwenkbar. Der freie Armteil ist mit Vakuumsaugern versehen und dient nur zum Abziehen des Kartonzuschnitts vom Stapel, also zum Vereinzeln. Der zweite Armteil dient nur zum Umlegen des Zuschnitts in eine waagrechte Position. In dieser Position geben die Vakuumsauger den Kartonzuschnitt frei, so dass dieser auf eine zum Aufrichtewerk führende Förderbahn abgelegt werden kann. Der endlose Kreisbetrieb der Vereinzelungsvorrichtung verringert zwar den Zeitaufwand für die Umsetzung der Kartonzuschnitte. Die Vorrichtung weist jedoch den Nachteil auf, dass der für die Vereinzelung und Umlegung benötigte Raum nach wie vor relativ gross ist. Zudem ist die Vereinzelungsvorrichtung in ihrer Gestaltungsform unflexibel, so dass für die Integration der Vorrichtung in die gesamte Maschine notwendige Anpassungen an der anschliessenden Förderbahn vorgenommen werden müssen.For example, EP-A-1'184'161 discloses an erecting machine of boxes from cardboard blanks, their separating device has a rotatable, two-part arm. The axis of rotation of the arm is below that Conveyor track so that it does not interfere with other machine components collided. The two parts of the arm are articulated together and by means of a controlled Drive can be pivoted against each other. The free one Arm part is provided with vacuum suction cups and is only used for Remove the cardboard blank from the stack, so that it can be separated. The second arm section is only used to fold the blank in a horizontal position. In this position the vacuum cups release the cardboard blank so that this is placed on a conveyor track leading to the erection unit can be. The endless circular operation of the separating device reduces the time required for the implementation of the cardboard blanks. The device has however, the disadvantage of that for the singulation and reallocation still required relatively large space is. In addition, the separating device is in its design inflexible, so for the integration of the Device in the entire machine necessary adjustments be carried out on the subsequent conveyor track have to.

EP-A-0'825'111 offenbart eine Maschine zum Aufrichten von Schachteln, bei welcher die Vereinzelungsvorrichtung ebenfalls einen mehrteiligen Arm aufweist. Ein unterer Armteil bewegt sich entlang einer Kurvenbahn auf und ab. Zudem ist er über eine längenveränderbare Strebe mit einem oberen, schwenkbaren Arm verbunden, welcher mit Vakuumsaugern versehen ist, um einen Kartonzuschnitt vom Magazinstapel zu entnehmen und in eine waagrechte Position zu schwenken.EP-A-0'825'111 discloses a machine for erecting Boxes in which the separating device also has a multi-part arm. A lower one Arm part moves up and down along a curved path. In addition, it has a length-adjustable strut with a upper, swiveling arm connected, which with vacuum suction cups is provided to cut a cardboard blank from the stack of magazines can be removed and placed in a horizontal position to pan.

In EP-A-0'761'535 ist ferner eine Verpackungsmaschine zum Aufrichten, Befüllen und Verschliessen von Kartons offenbart. Dabei werden entweder Kartonzuschnitte oder bereits geklebte, aber flachgefaltete Kartonrohlinge von einer Entnahmevorrichtung in eine Befüllstation transportiert. In ersten Ausführungsformen weist die Entnahmevorrichtung ein zweiarmiges, mit Vakuumsauger versehenes Entnahmegestell auf, welches an einem Tragarm befestigt ist. Der Tragarm ist um circa 90° schwenkbar in einem in horizontaler Richtung verschiebbaren Schlitten gelagert, welcher der Förderung des bereits umgesetzten Rohlings zur Befüllstation dient. Zuerst wird somit der Schwenkarm geschwenkt und anschliessend erst erfolgt die Verschiebung des Schlittens. In den anderen Ausführungsformen wird das Entnahmegestell zwecks Umsetzung nicht geschwenkt, sondern auf und ab bewegt. Diese Entnahmevorrichtungen benötigen relativ viel Raum. Da sie zudem die Rohlinge bis zur Befüllstation transportieren, ist die Leistungsfähigkeit der Verpackungsmaschine stark begrenzt. EP-A-0'761'535 also describes a packaging machine for Erecting, filling and closing of cartons disclosed. This will either cut cardboard or already glued but flat folded cardboard blanks from one Removal device transported to a filling station. In first embodiments, the removal device a two-armed removal frame provided with a suction cup on which is attached to a support arm. The Support arm can be swiveled by approximately 90 ° in a horizontal position Slidable in the direction of which slides conveying the already transferred blank to the filling station serves. First the swivel arm is swiveled and only then does the shift take place of the sled. In the other embodiments Tapping frame not pivoted for implementation, but instead moved up and down. These removal devices need relatively much space. Since they also the blanks up Transport to the filling station is the performance the packaging machine is severely limited.

Darstellung der ErfindungPresentation of the invention

Es ist deshalb Aufgabe der Erfindung, eine Vereinzelungsvorrichtung einer Kartoniermaschine, insbesondere eines Kartonaufrichters, zu schaffen, welche platzsparend ausgebildet ist, eine flexible Integration in die Kartoniermaschine erlaubt und eine effiziente Umsetzung von Kartonzuschnitten ermöglicht.It is therefore an object of the invention to provide a separating device a cartoning machine, especially one Carton erector, which is designed to save space is a flexible integration into the cartoning machine allowed and efficient implementation of cardboard blanks allows.

Diese Aufgabe löst eine Vorrichtung mit den Merkmalen des Patentanspruchs 1.This object is achieved by a device with the features of Claim 1.

Die erfindungsgemässe Vereinzelungsvorrichtung dient zur einzelnen Entnahme von Kartonzuschnitten aus einem Magazin und zur Umsetzung des entnommenen Kartonzuschnitts von einer Entnahmeposition in eine Übergabeposition. Die Vorrichtung weist einen motorisch angetriebenen Schwenkarm und daran angeordnete Mittel zur vereinzelten Entnahme des Kartonzuschnitts auf und ist dadurch gekennzeichnet, dass der Schwenkarm auf einem geradlinig verschiebbaren Schlitten angeordnet ist, wobei während der Entnahme und Umsetzung des Kartonzuschnitts eine Schwenkbewegung des Schwenkarms von einer geradlinigen Bewegung des Schlittens überlagert ist.The separating device according to the invention is used for individual removal of cardboard blanks from a magazine and to implement the removed cardboard blank from a removal position to a transfer position. The The device has a motor-driven swivel arm and means arranged thereon for individual removal of the cardboard blank and is characterized by that the swivel arm can be moved on a straight line Sledge is arranged, during the removal and implementation of the cardboard blank a pivoting movement of the swivel arm from a linear movement of the Sled is overlaid.

Die erfindungsgemässe Vorrichtung kombiniert somit gleichzeitig eine Schwenkbewegung mit einer translatorischen Bewegung. Die Entnahme und Umsetzung eines einzelnen Kartonzuschnitts ist eine fliessende Bewegung, bei welcher der Schwenkarm um den gewünschten Winkel gedreht wird und gleichzeitig hin und her geschoben wird. Dadurch lässt sich seine Lage zum verbleibenden Stapel jeweils so einstellen, dass die dem Stapel am nächsten liegende Kante des entnommenen Kartonzuschnitts stets möglichst nahe bei der Stapeloberfläche liegt. Zudem kann die Umsetzbewegung, das heisst die Schwenkbewegung, bereits kurz nach der Entnahme gestartet werden. Die Umsetzung des Kartonzuschnitts von seiner senkrechten in eine waagrechte Lage lässt sich somit innerhalb eines minimierten Raums verwirklichen, da er sich auf einer optimierten Raumkurve bewegen kann. Die Vereinzelungsanlage lässt sich dadurch platzsparend und kompakt ausbilden. Zudem wird auch der benötigte Zeitaufwand für die Entnahme und Umsetzung minimiert.The device according to the invention thus combines at the same time a pivoting movement with a translatory Move. The removal and implementation of an individual Carton blanking is a flowing movement, at which the swivel arm rotated by the desired angle is being pushed back and forth at the same time. Thereby its position in relation to the remaining stack can be so set the edge closest to the stack of the removed cardboard blank always as close as possible lies on the stack surface. In addition, the transfer movement, that is, the swivel movement, shortly after the removal can be started. Implementation of the cardboard blank from its vertical to a horizontal position can thus be realized within a minimized space, since he is on an optimized space curve can move. The separation system can be training space-saving and compact. In addition, the minimized the time required for removal and implementation.

Der Weg des Schlittens lässt sich beliebig lange ausbilden, so dass der Schlitten nach der Drehung des Arms noch zusätzlich eine rein translatorische Bewegung ausführen kann, um den entnommenen Kartonzuschnitt an die gewünschte Übergabestelle zu bringen. Die Vereinzelungsvorrichtung lässt sich dadurch auf einfache Weise in Kartoniermaschinen integrieren.The route of the sledge can be formed as long as you like, so that the sled still after the rotation of the arm additionally perform a purely translatory movement can to cut the removed carton to the desired Bring transfer point.

Die im folgenden beschriebene Vereinzelungsvorrichtung ist Bestandteil einer Kartoniermaschine, insbesondere eines Kartonaufrichters und/oder eines Kartonverdecklers. Derartige Kartoniermaschinen sind im Stand der Technik bekannt und werden deshalb im folgenden nicht im Detail beschrieben. Sie weisen im wesentlichen wie eingangs erwähnt ein Magazin mit einem Stapel flacher Kartonzuschnitte, eine Vereinzelungsvorrichtung, ein Aufrichtewerk und mindestens einen Förderer auf. Die Vereinzelungsvorrichtung wird im allgemeinen auf einem Rahmengestell der Maschine angeordnet. Es ist jedoch auch möglich, sie mit einem eigenen Rahmengestell zu versehen. Diese Gestelle sind im folgenden weder gezeigt noch beschrieben.The separating device described below is part of a cartoning machine, especially one Carton erector and / or a carton capper. Cartoning machines of this type are state of the art known and are therefore not in the following in detail described. They point essentially as mentioned at the beginning a magazine with a stack of flat cardboard blanks, a separating device, an erection unit and at least one sponsor. The separating device is generally on a rack arranged the machine. However, it is also possible to provide them with their own frame. These frames are neither shown nor described in the following.

In den Figuren 1a und 1b ist eine erste Ausführungsform der erfindungsgemässen Vereinzelungsvorrichtung dargestellt. Sie weist einen Schlittenrahmen 1 auf, welcher am oben erwähnten Gestell befestigbar ist. Der Schlittenrahmen 1 verfügt über mindestens einen Führungsstab 10. Hier sind es zwei Führungsstäbe 10. Auf diesen Führungsstäben 10 ist ein Schlitten 2 geradlinig verschiebbar gelagert. Der Schlitten 2 wird mittels einer translatorischen Antriebseinheit 3 angetrieben. Diese Antriebseinheit 3 weist einen ersten Motor 30 auf, dessen Antriebsachse mit einer ersten Antriebsrolle 31, vorzugsweise einem Zahnrad, verbunden ist. Der erste Motor 30 ist vorzugsweise ein Servomotor mit einem Winkeltrieb. Ein erstes Endlosband 33, vorzugsweise ein erster Zahnriemen, verbindet die erste Antriebsrolle 31 mit einer ersten Umlenkrolle 32, welches ebenfalls vorzugsweise ein Zahnrad ist. Der Schlitten 2 ist mit dem ersten Endlosband 33 fest verbunden. Andere bekannte Arten eines translatorischen Antriebs für den Schlitten sind jedoch auch möglich.A first embodiment is shown in FIGS. 1a and 1b of the separating device according to the invention. It has a slide frame 1, which on above mentioned frame is attachable. The sled frame 1 has at least one management staff 10. Here there are two guide rods 10. On these guide rods 10, a carriage 2 is mounted so that it can be displaced in a straight line. The carriage 2 is driven by means of a translatory drive unit 3 driven. This drive unit 3 has a first motor 30, the drive axis with a first drive roller 31, preferably a gear wheel, connected is. The first motor 30 is preferably a servo motor with an angular drive. A first endless belt 33, preferably a first toothed belt, connects the first drive roller 31 with a first deflection roller 32, which is also preferably a gear. The Carriage 2 is firmly connected to the first endless belt 33. Other known types of translatory drives for the sledge are also possible.

Die Antriebsachse des ersten Motors 30 verläuft in diesem Beispiel senkrecht zur Verschiebungsrichtung des Schlittens 2. Das heisst, der Schlitten 2 bewegt sich in mindestens annähernd horizontaler Richtung hin und her und die Antriebsachse verläuft vertikal. Die Grundposition des Schlittens 2 wird mittels eines Sensors 7 erkannt.The drive axis of the first motor 30 runs in this Example perpendicular to the direction of displacement of the slide 2. That is, the carriage 2 moves in at least approximately horizontal direction back and forth and the drive axis runs vertically. The basic position of the carriage 2 is detected by means of a sensor 7.

Auf dem Schlitten 2 ist ein motorisch angetriebener Schwenkarm 5 angeordnet. Der Antrieb des Schwenkarms 5 erfolgt mittels einer Rotationsantriebseinheit 4, welche ebenfalls auf dem Schlitten 2 befestigt ist. Diese Einheit 4 weist einen zweiten Motor 40 auf, vorzugsweise ebenfalls einen Servomotor mit Winkeltrieb. Im hier dargestellten Beispiel verläuft die Antriebsachse des zweiten Motors 40 in vertikaler Richtung und der Schwenkarm 5 ist mit einer horizontal verlaufenden Umlenkachse verbunden. Beide Motoren 30, 40 sind mit einer Steuerung S der Kartoniermaschine verbunden. Wird die Kartoniermaschine taktweise betrieben, so werden auch die Antriebe der Schwenkachse 5 und des Schlittens 2 taktweise betrieben, vorzugsweise im Takt der restlichen Maschine beziehungsweise des Aufrichtewerks.On the carriage 2 is a motor-driven Swivel arm 5 arranged. The drive of the swivel arm 5 takes place by means of a rotary drive unit 4, which is also attached to the carriage 2. This unity 4 has a second motor 40, preferably also a servo motor with an angular drive. Im shown here Example runs the drive axis of the second Motors 40 in the vertical direction and the swivel arm 5 is connected to a horizontally extending deflection axis. Both motors 30, 40 are with a control S connected to the cartoning machine. The cartoning machine operated in cycles, so are the drives the pivot axis 5 and the slide 2 operated in cycles, preferably in time with the rest of the machine or of the straightener.

Der Schwenkarm 5 ist vorzugsweise starr ausgebildet und zu einem Winkel geformt. Der Arm 5 weist dabei zwei ungleich lange Schenkel auf, wobei der erste, kürzere Schenkel 50 mit dem Antrieb verbunden ist. Der zweite, längere und freie Schenkel 51 ragt über den Schlitten 2 hinaus und ist mit Mittel zur Entnahme von Kartonzuschnitten versehen. Als Mittel lässt sich alles einsetzen, was sich zur Ergreifung und zum Festhalten des Kartonzuschnitts während der Umsetzung eignet. Vorzugsweise werden jedoch Vakuumsauger eingesetzt, welche mit einer Unterdruckquelle verbunden sind. Die erwähnten Mittel bestehen deshalb in diesem Beispiel aus einer Saugerhalterung 6 und mindestens einem vakuumsauger 64. Damit die Lage des mindestens einen Vakuumsaugers 64, insbesondere entsprechend der Art der Kartoniermaschine und der Form der Kartonzuschnitte, angepasst werden kann, weist die Saugerhalterung 6 einen Trägerbalken 60 und mindestens eine Saugerleiste 62 auf. Hier sind es zwei Saugerleisten 62, welche jede mindestens je einen, hier genau einen, Saugnapf 64 aufweisen. Der Trägerbalken 60 ist quer zur Längsrichtung des Schwenkarms 5 verlaufend fest an dessen freien Ende befestigt. Die Saugerleisten 62 sind parallel zur Längsrichtung des Schwenkarms 5 verlaufend am Trägerbalken 60 angeordnet, wobei sie innerhalb von Verschiebenuten 61, 61' in zwei senkrecht zueinander stehenden Richtungen verschiebbar sind und in ihrer jeweiligen Position durch ein Befestigungsmittel 63, vorzugsweise durch eine Schraubverbindung, fixierbar sind.The swivel arm 5 is preferably rigid and shaped into an angle. The arm 5 has two unequal long legs, with the first, shorter Leg 50 is connected to the drive. The second, longer and free leg 51 protrudes over the slide 2 and is provided with means for removing cardboard blanks Mistake. Anything can be used as a means what to take and hold the cardboard blank suitable during implementation. Preferably However, vacuum cups are used, which with a Vacuum source are connected. The means mentioned exist therefore in this example from a suction cup holder 6 and at least one vacuum suction device 64 Location of the at least one vacuum suction device 64, in particular according to the type of cartoning machine and the shape the cardboard blanks, can be adjusted, shows the Suction cup holder 6 a support beam 60 and at least a squeegee 62. There are two squeegees here 62, each of which has at least one, here exactly one, Have suction cup 64. The support beam 60 is transverse to Longitudinal direction of the swivel arm 5 running firmly on it attached free end. The suction strips 62 are parallel to the longitudinal direction of the swivel arm 5 extending on the support beam 60 arranged, being within sliding grooves 61, 61 'in two mutually perpendicular Directions are shiftable and in their respective position by a fastener 63, preferably can be fixed by a screw connection.

Anhand der Figuren 2a bis 2d lässt sich die Arbeitsweise der erfindungsgemässen Vorrichtung erkennen. Mit M ist ein Magazin mit gestapelten Kartonzuschnitten bezeichnet. Das Bezugszeichen Z zeigt den obersten, gerade dem Stapel entnommenen Kartonzuschnitt. Die gestapelten Kartonzuschnitte verlaufen mindestens annähernd senkrecht oder, wie hier dargestellt, in einem bezüglich der Vertikalen kleinen Winkel zur Vorrichtung hin geneigt und werden bei der Umsetzung in eine mindestens annähernd waagrechte Position gebracht.The mode of operation can be seen from FIGS. 2a to 2d recognize the device according to the invention. With M is called a magazine with stacked cardboard blanks. The reference symbol Z shows the topmost, just the stack removed cardboard blank. The stacked cardboard blanks run at least approximately vertically or, as shown here, in one with respect to the vertical small angle towards the device and are at the implementation in an at least approximately horizontal position brought.

Wie in Figur 2a erkennbar ist, wird der Schwenkarm 5 hochgeschwenkt und werden die Saugnäpfe 64 zur Anlage an den vordersten Kartonzuschnitt Z gebracht, um diesen Kartonzuschnitt Z zu entnehmen. Anschliessend wird der Schlitten 2 um eine kurze Strecke von der Stapeloberfläche weggefahren, um den Kartonzuschnitt Z abzuziehen, wie dies in Figur 2a dargestellt ist. Unmittelbar nach diesem Abziehen setzt bereits die Schwenkbewegung des Arms 5 an. Bei der nachfolgenden Schwenkbewegung wird der Schlitten 2 wieder zur Stapeloberfläche hin gefahren; wie dies in Figur 2b ersichtlich ist. In Figur 2c ist erkennbar, dass der Schlitten 2 immer näher zur Stapeloberfläche hin gefahren wird, je mehr der Arm 5 den Kartonzuschnitt Z umsetzt und dieser sich der mindestens annähernd waagrechten Übergabeposition nähert. In der Übergabeposition wird der Kartonzuschnitt Z üblicherweise auf einen Förderer abgelegt und durch Anhebung des Drucks vom Vakuumsauger freigegeben. In Figur 2d ist der Bewegungsablauf in einzelnen Positionen festgefroren, welche überlagert dargestellt sind. Es ist erkennbar, dass die Schwenkbewegung des Schwenkarms 5 und die geradlinige Bewegung des Schlittens 2 überlagert sind, wobei der Schlitten 2 zuerst vom Stapel weg- und dann zu ihm hin gefahren wird. Dabei befindet sich die unterste Kante K des Kartonzuschnitts Z stets so nah wie möglich bei der Stapeloberfläche. Beachtenswert ist, dass für diese gezielte und platzsparende Umsetzung keine vertikale translatorische Verschiebung des Schwenkarms 5 notwendig ist. Falls sich die Übergabestelle, beispielsweise auf einen Förderer, weiter weg befindet, so kann der Schlitten 2 anschliessend noch ohne Schwenkbewegung des Arms 5 um die gewünschte Strecke verschoben werden.As can be seen in FIG. 2a, the swivel arm 5 pivoted up and the suction cups 64 to the system brought the frontmost cardboard blank Z to this cardboard blank Z can be seen. Then the Slide 2 a short distance from the stacking surface moved away to pull off the cardboard blank Z, like this is shown in Figure 2a. Immediately after this Pulling off starts the pivoting movement of the arm 5. With the subsequent swivel movement, the carriage 2 moved back to the stack surface; like this in Figure 2b can be seen. In Figure 2c it can be seen that the carriage 2 moved ever closer to the stack surface the more the arm 5 implements the cardboard blank Z. and this is the at least approximately horizontal Transfer position is approaching. In the transfer position the cardboard blank Z usually on a conveyor stored and by increasing the pressure from the vacuum cup Approved. The sequence of movements is shown in detail in FIG. 2d Frozen positions, which are shown superimposed are. It can be seen that the pivoting movement of the swivel arm 5 and the linear movement of the Carriage 2 are superimposed, the carriage 2 first is removed from the stack and then driven towards it. The bottom edge K of the cardboard blank is located Z always as close as possible to the stack surface. It is worth noting that for this targeted and space-saving implementation no vertical translational Displacement of the swivel arm 5 is necessary. In case the transfer point, for example to a conveyor, is further away, the carriage 2 can then still without pivoting the arm 5 around the desired one Distance to be moved.

In den Figuren 3a und 3b ist ein zweites Ausführungsbeispiel dargestellt. Es ist im wesentlichen gleich aufgebaut wie das erste Beispiel. Gleiche Teile wurden deshalb mit gleichen Bezugszeichen versehen und werden nicht mehr im Detail beschrieben. Der wesentliche Unterschied besteht darin, dass nun die Motoren 30, 40 horizontal ausgerichtet sind. Für den Schlittenantrieb ist keine Umlenkung mehr notwendig. Die Antriebsrolle 31 kann direkt mit der Motorwelle verbunden werden. Die Rotationsantriebseinheit 4 hingegen weist nun eine mit der Motorwelle des zweiten Motors 40 verbundene zweite Antriebsrolle 41, eine zweite Umlenkrolle 42 und ein die zwei Rollen verbindendes zweites Endlosband 43 auf. Auch hier wird vorzugsweise ein Zahnriemenantrieb verwendet. Beide Rollen 41, 42 sind im Schlitten 2 gelagert. In beiden Ausführungsbeispielen wird der zweite Motor 40 mit dem Schlitten 2 mitbewegt.A second exemplary embodiment is shown in FIGS. 3a and 3b shown. It is structured essentially the same like the first example. The same parts were therefore provided with the same reference numerals and are no longer described in detail. The main difference is in that the motors 30, 40 are now aligned horizontally are. There is no redirection for the slide drive more necessary. The drive roller 31 can directly with the motor shaft. The rotary drive unit 4, however, now has one with the motor shaft of the second motor 40 connected second drive roller 41, a second deflection roller 42 and a connecting the two rollers second endless belt 43. Here too is preferred a toothed belt drive is used. Both roles 41, 42 are mounted in the carriage 2. In both embodiments the second motor 40 with the carriage 2 moved.

Es sind jedoch auch Ausführungsformen möglich, bei welchen die Rotationsantriebseinheit getrennt vom Schlitten angeordnet ist und nicht mit diesem verfährt.However, embodiments are also possible in which the rotary drive unit separate from the carriage is arranged and does not deal with this.

Eine Ausrichtung der Kartonzuschnitte in mindestens annähernd senkrechter Richtung und ihre Umsetzung in eine mindestens annähernd waagrechte Position ist bevorzugt. Andere Anordnungen sind jedoch auch möglich. So kann der Schwenkarm 5 auch um einen Winkel grösser oder kleiner als der hier gezeigte 90° Winkel geschwenkt werden. Entsprechend der Anordnung des Stapels und der gewünschten Ausrichtung der Übergabeposition wird auch die Verschiebungsrichtung des Schlittens 2 gewählt. Er kann somit auch entlang einer schiefen Ebene oder vertikal verlaufen. Vorzugsweise befindet sich bei einer waagrechten Übergabeposition die Rotationsachse tiefer als diese Position, so dass sie nicht mit anderen Maschinenkomponenten kollidiert und der Schwenkwinkel minimiert ist. Bei einer anderen Lage der Übergabeposition ist die Achse sinngemäss angeordnet. Weiterhin können bewegte Teile der Vorrichtung zwecks Massenreduktion und/oder spezifischer Steifigkeitserhöhung aus Verbundwerkstoffen, z.B. faserverstärkten Kunststoffen oder insbesondere kohlefaserverstärkten Kunststoffen, eingesetzt werden.Alignment of the cardboard blanks in at least approximately vertical direction and its implementation in one at least approximately horizontal position is preferred. However, other arrangements are also possible. So he can Swivel arm 5 also larger or smaller by an angle than the 90 ° angle shown here. Corresponding the arrangement of the stack and the desired one Alignment of the transfer position also becomes the direction of displacement of the carriage 2 selected. So he can also run along an inclined plane or vertically. Preferably located on a horizontal Transfer position the axis of rotation lower than this position, so they are not with other machine components collides and the swivel angle is minimized. at Another position of the transfer position is the axis arranged accordingly. Moving parts of the Device for mass reduction and / or more specific Increase in stiffness from composite materials, e.g. fiber reinforced Plastics or in particular carbon fiber reinforced Plastics.

In den Figuren 4 und 5a bis 5e ist eine dritte Ausführungsform dargestellt, welche einen Teil der oben genannten Varianten aufweist. So ist die Rotationsantriebseinheit 4 lagefest angeordnet und bewegt sich nicht mit dem Schlitten 2. Zur Übertragung der Rotationsbewegung des Antriebsmotors der Rotationsantriebseinheit 4 auf den Schwenkarm 5 ist eine Kurbelstange 44 vorhanden. In den Figuren 5a bis 5e ist ersichtlich, dass auch hier der Schlitten 2 je nach Entstapelungsposition transversal nach vorne oder nach hinten bewegt wird und dass eine entsprechende Schwenkbewegung des Schwenkarms 5 überlagert wird. Die Verschiebungsrichtung des Schlittens 2 liegt hier vorzugsweise in einer schiefen Ebene, wobei der Schlitten benachbart zum Magazin M seine höchste Position einnimmt.A third embodiment is shown in FIGS. 4 and 5a to 5e shown, which is part of the above Has variants. So is the rotary drive unit 4 is fixed in position and does not move with the Carriage 2. To transmit the rotational movement of the Drive motor of the rotary drive unit 4 on the A crank rod 44 is present in the swivel arm 5. In the FIGS. 5a to 5e show that here too Carriage 2 transversely depending on the unstacking position is moved forward or backward and that one corresponding pivoting movement of the swivel arm 5 is superimposed becomes. The direction of displacement of the carriage 2 is preferably in an inclined plane, whereby the slide is next to magazine M in its highest position occupies.

In der in Figur 4 dargestellten Ausführungsform sind am Schwenkarm 5 mindestens vier, vorzugsweise genau vier Vakuumsauger 64 angeordnet. Je zwei Vakuumsauger 64 sind hierfür an je einem Ende einer Saugerleiste 62 in ihrer relativen Lage zueinander verschiebbar angeordnet. Die Verwendung von mindestens vier Vakuumsaugern hat den Vorteil, dass die Kartonzuschnitte Z sicher gehalten und geführt werden. Insbesondere die Entstapelung wird dadurch vereinfacht.In the embodiment shown in Figure 4 are on Swivel arm 5 at least four, preferably exactly four vacuum suction cups 64 arranged. There are 64 suction cups 64 each for this at one end of a squeegee 62 in their relative to each other slidably arranged. The The use of at least four vacuum cups has the advantage that the cardboard blanks Z are securely held and guided become. In particular, this will unstack simplified.

In Figur 6 ist eine bevorzugte Ausführungsform eines Vakuumsaugers 64 dargestellt. Er weist einen Befestigungsblock 65 zur lösbaren Befestigung an der Saugerleiste 62 auf und einen über eine Feder 66 daran gefedert befestigten Saugkopf 67. Die gefederte Ausbildung des Vakuumsaugers 64 vereinfacht das Abziehen des Kartonzuschnitts Z vom Stapel, da Toleranzen in der Zustellung des Schlittens überbrückt werden können und die sichere Anlage aller Saugnäpfe am Kartonzuschnitt Z gewährleistet wird.6 shows a preferred embodiment of a vacuum suction device 64 shown. He has a mounting block 65 for detachable attachment to the squeegee 62 on and one attached to it via a spring 66 Suction head 67. The sprung design of the vacuum suction cup 64 simplifies the removal of the cardboard blank Z off the stack because of tolerances in the delivery of the carriage can be bridged and the safe investment of all Suction cups on the cardboard blank Z is guaranteed.

Die erfindungsgemässe Vorrichtung ermöglicht somit eine platzsparende und effiziente Umsetzung einzelner Kartonzuschnitte und lässt sich zudem flexibel in Kartoniermaschinen integrieren. The device according to the invention thus enables space-saving and efficient implementation of individual cardboard blanks and can also be flexibly used in cartoning machines integrate.
