Description

Die Erfindungen betreffen einerseits eine Beschickungsvorrichtung für Kartons, bei der mindestens zwei für eine Aufnahme und Abgabe von Kartonzuschnitten ausgebildete Magazine eingesetzt werden, und wobei die Kartonzuschnitte über ein greifendes Mittel einer die Kartonzuschnitte formenden und die Kartonzuschnitte verleimenden Maschine zugeführt werden, und andererseits ein Verfahren zum Betreiben einer derartigen Beschickungsvorrichtung.On the one hand, the inventions relate to a loading device for boxes with at least two for one Receiving and delivering trained cardboard blanks Magazines are used, and taking the cardboard blanks the cardboard blanks via a gripping means forming machine and glueing the cardboard blanks are supplied, and on the other hand a method for Operating such a loading device.

Es ist bekannt, daß Kartonzuschnitte für Verpackungsmaschinen gestapelt in einem Magazin bereitgestellt werden. Aus einem derartigen Magazin werden die Kartonzuschnitte einzeln mittels eines greifenden Mittels, zum Beispiel eines an einem pendelnd bewegten Hebel befestigten Saugnapfes entnommen und der weiteren Bearbeitung zugeführt. Es ist weiter aus der DE-A-1 961 300, dem nächstliegenden Stand der Technik bekannt, daß einem ersten Magazin ein zweites mit Kartonzuschnitten bevorratetes Magazin benachbart ist, welches nach der Leerung des ersten Magazins gegen das erste Magazin ausgetauscht wird.It is known that carton blanks for packaging machines stacked in a magazine. The cardboard blanks are made from such a magazine individually by means of a gripping means, for example one attached to an oscillating lever Suction cup removed and further processing fed. It is further from DE-A-1 961 300, the closest prior art announced that a first magazine a second magazine stocked with cardboard blanks is adjacent, which after emptying the first Magazine is exchanged for the first magazine.

Um unterschiedlich bedruckte Kartons am Ende einer Verpackungsreihe in alternierender Weise in einem Sammelbehälter zu erreichen, werden die unterschiedlich bedruckten Kartonzuschnitte alternierend in ein Magazin eingelegt. Dann folgt jedem Kartonzuschnitt ein anders bedruckter Kartonzuschnitt, oder jeweils einer genauen Anzahl an Kartonzuschnitten folgt die gleiche Anzahl an Kartonzuschnitten in anderer Bedruckung. Dies hat den Nachteil, daß ein relativ aufwendiger Sortiervorgang vor der Einbringung eines Stapels an Kartonzuschnitten in ein Magazin erfolgen muß. Ein weiterer Nachteil ist, daß eine Umstellung einer bestimmten Alternierung, zum Beispiel von direkt aufeinander wechselnden Kartonzuschnittbedruckungen, nur durch eine Änderung der Vorsortierung erreichbar ist, und eine derartige Umstellung bei laufender Beschickungsvorrichtung nicht sofort erfolgen kann, da erst mindestens das eingesetzte Magazin geleert wird. Auch eine schnelle Umstellung auf noch mehr verschiedene Kartonzuschnittbedruckungen ist aus den genannten Gründen problematisch.To differently printed boxes at the end of one Packing series alternately in one To reach the collection containers, they are different printed cardboard blanks alternately in a magazine inserted. Then each box cut follows a different one printed cardboard blank, or an exact one Number of cardboard blanks follows the same number Cardboard blanks in a different print. This has the Disadvantage that a relatively complex sorting process inserting a stack of cardboard blanks into one Magazine must be done. Another disadvantage is that a Change of a certain alternation, for example from directly alternating cardboard blank printing, can only be reached by changing the pre-sorting, and such a changeover with the loading device running cannot take place immediately because at least the magazine used is emptied. Also a quick one Changeover to even more different cardboard blank printing is problematic for the reasons mentioned.

Den Erfindungen liegen die Aufgaben zugrunde, eine Beschickungsvorrichtung für Kartons und ein Verfahren zum Betreiben einer derartigen Beschickungsanlage zu finden, so daß ein problemloses und sofortiges Einsetzen oder Abändern einer bestimmten Alternierungsreihenfolge für unterschiedlich bedruckte Kartonzuschnitte, auch bei laufendem Verpackungsprozeß, möglich ist. Zudem soll ein Sortiervorgang von unterschiedlich bedruckten Kartonzuschnitten mitsamt dem nachfolgenden Einfüllen der sortierten Kartonzuschnitte in ein Magazin entfallen.The inventions are based on the tasks, one Carton loading device and method for Operating such a feed system to find that a trouble-free and immediate insertion or modification a certain alternation order for different printed cardboard blanks, even while it is running Packaging process, is possible. A sorting process should also be carried out of differently printed cardboard blanks together with the subsequent filling of the sorted Cardboard blanks in a magazine are not required.

Gelöst sind die Aufgaben gemäß den Ansprüchen 1 und 8. The tasks according to claims 1 and 8 are solved.

Die Magazine sind starr miteinander verbunden, um zu erreichen, daß die Zuführung eines Magazins gleichzeitig das Entfernen eines anderen Magazins bewirkt. Bei einer Verschiebung der Magazine entlang einer geraden Strecke sind zudem die wirkenden Kräfte minimal. Die Strecke verläuft zudem senkrecht zur Bewegungsrichtung des die Kartonzuschnitte greifenden Mittels, so daß die Verschiebedistanzen minimal sind und das greifende Mittel normal auf einer Oberfläche eines Kartonzuschnitts angreifen kann. The magazines are rigid with each other connected to achieve the supply of a Magazine at the same time removing another magazine causes. When the magazines are moved along a the straight forces are minimal. The route also runs perpendicular to the direction of movement of the means gripping the cardboard blanks so that the Displacement distances are minimal and the gripping means normal on a surface of a cardboard blank can attack.

Die erfindungsgemäße Beschickungsvorrichtung und das erfindungsgemäße Verfahren haben auch den Vorteil, daß ein problemloses und sofortiges Einsetzen oder Abändern einer bestimmten Alternierungsreihenfolge für unterschiedlich bedruckte Kartonzuschnitte, auch bei laufendem Verpackungsprozeß, möglich ist. In jedes Magazin wird ein Stapel gleichartig bedruckter Kartonzuschnitte eingesetzt. Jedes Magazin wird dabei mit anders bedruckten Kartonzuschnitten bestückt. Je nach Betriebsmodus werden die Magazine derart verschoben, daß entweder nach jeder Entnahme eines Kartonzuschnitts aus einem Magazin ein anderes Magazin in die Position verschoben wird, bei der das greifende Mittel erneut einen Kartonzuschnitt greift. Oder ein Magazin verbleibt für mehrere Greifvorgänge in der Position, in der es das greifende Mittel versorgt und anschließend wird ein anderes Magazin mit Kartonzuschnitten mit anderem Druckbild in die das greifende Mittel versorgende Position geschoben und verweilt dort für die Dauer von gleichviel Greifvorgängen. Dabei wird die Zeitspanne zwischen zwei aufeinanderfolgenden Greifvorgängen genutzt, die Behälter zu verschieben. Durch den Wechsel der Behälter, der auch während des Betriebs der Beschickungsvorrichtung erfolgen kann, wird der bekannte Sortiervorgang von unterschiedlich bedruckten` Kartonzuschnitten und das nachfolgende Einfüllen der sortierten Kartonzuschnitten in ein Magazin vermieden.The loading device according to the invention and that Methods according to the invention also have the advantage that a problem-free and immediate insertion or modification of one certain alternation order for different printed cardboard blanks, even while it is running Packaging process, is possible. There is a in each magazine Stack of similarly printed cardboard blanks used. Each magazine is printed differently Cardboard blanks equipped. Depending on the operating mode the magazines moved so that either after each Removing a cardboard blank from a magazine other magazine is moved to the position at which the gripping agent grabs a cardboard blank again. Or a magazine remains in the for several gripping processes Position in which it supplies the gripping agent and then another magazine with cardboard blanks is cut with a different print in which the gripping medium supply position pushed and lingers there for the Duration of the same number of gripping processes. The Period between two consecutive Gripping processes used to move the container. By the change of the container, which also during the operation of the Feeding device can be done, the known Sorting process of differently printed` Cardboard blanks and the subsequent filling of the sorted carton blanks avoided in a magazine.

Weitere vorteilhafte Ausgestaltungen der Erfindungen werden in den Ansprüchen 2 bis 8 und 10 bis 16 beschrieben. Further advantageous embodiments of the inventions will be described in claims 2 to 8 and 10 to 16.

Eine Beschickungsvorrichtung auf mindestens einer Kugelrollbuchse zu lagern (Anspruch 2) hat den Vorteil, daß die Reibungskräfte beim Verschieben der Beschickungsvorrichtung minimalisiert sind, und somit das Verschieben der Beschickungsvorrichtung relativ leichtgängig und schnell erfolgt. Die gleichen Vorteile sind bei Einsatz eines pneumatischen Zylinders als Antrieb für die Magazine (Anspruch 3) gegeben.A loading device on at least one Ball roller bushing to store (claim 2) has the advantage that the frictional forces when moving the loading device are minimized, and thus moving the loading device relatively smooth and done quickly. The same advantages are in use a pneumatic cylinder as a drive for the magazines (Claim 3) given.

Ist an dem die Kartonzuschnitte greifendem Mittel analog Anspruch 4 mindestens ein Saugnapf vorgesehen, so ist ein zuverlässiges und bewährtes greifendes Mittel eingesetzt. Der Saugnapf kann entweder allein durch den beim Drücken gegen einen Kartonzuschnitt erreichten Unterdruck am Saugnapf einen Kartonzuschnitt greifen, weiterreichen und sich durch Zugkraft wieder vom Kartonzuschnitt lösen, oder aber die Leistung eines Saugnapfes wird unterstützt. Gemäß Anspruch 5 kann ein Saugnapf dadurch eine größere Haltekraft aufbringen, wenn er mit einer Vakuumquelle verbunden ist. Ein am Saugnapf erzeugtes Vakuum erhöht zudem die Zuverlässigkeit des greifenden Mittels. Ist der Saugnapf mit einer Druckluftquelle verbunden (Anspruch 6), so kann das Ablösen des Saugnapfes von einem Kartonzuschnitt durch in den Saugnapf eingeleitete Druckluft erleichtert und beschleunigt werden. Mittel zur Zuschaltung und Abschaltung des Saugnapfes von der Vakuumquelle bzw. der Druckluftquelle erlauben dabei einen zeitgenauen Einsatz von Vakuum und Druckluft. Einen optimalen Einsatz erhält man, wenn man gemäß Anspruch 7 taktweise bei jedem Greifvorgang den Saugnapf als greifendes Mittel zuerst mit der Vakuumquelle, zum Greifen des Kartonzuschnitts, und dann mit der Druckluftquelle, zum Lösen des Kartonzuschnitts vom greifenden Mittel, verbindet.Is analogous to the means that grips the cardboard blanks Claim 4 provided at least one suction cup, so is a reliable and proven gripping agent used. The suction cup can either by pressing it against a vacuum cut to a carton cut Grab a box cut, pass it on and detach itself from the cardboard blank by traction, or but the performance of a suction cup is supported. According to Claim 5 can be a larger suction cup Apply holding force when using a vacuum source connected is. A vacuum created on the suction cup increases also the reliability of the interfering means. Is the Suction cup connected to a compressed air source (claim 6), so the detachment of the suction cup from one Cardboard blank cut into the suction cup Compressed air can be eased and accelerated. Means of Activation and deactivation of the suction cup from the Vacuum source or compressed air source allow one Precise use of vacuum and compressed air. One optimal use is obtained if, according to claim 7 intermittently with each gripping process the suction cup as gripping agent first with the vacuum source, for gripping of the cardboard blank, and then with the compressed air source to Detaching the cardboard blank from the gripping means, connects.

Werden die Magzine direkt und unmittelbar zeitlich nach jeweils einer erfolgten Entnahme eines Kartonzuschnitts verschoben, so ist eine maximale Arbeitsgeschwindigkeit der Beschickungsvorrichtung erreicht.Are the magazines immediately and immediately after each time a cardboard blank is removed postponed, so is a maximum Feeder operating speed reached.

Werden die Magazine nach jeder erfolgten Entnahme verschoben, so werden abwechselnd Kartons mit unterschiedlicher Bedruckung erzeugt. Am Ende der Verpackungsanlage erhält man somit gefüllte, verschlossene Kartons mit abwechselnder Bedruckung. Diese gefüllten Kartons werden in der Reihenfolge, in der sie erzeugt wurden, reihenweise in Sammelbehälter, zum Beispiel Trays oder große Kartons gepackt. Somit enthalten die Sammelbehälter die Kartons unterschiedlicher Bedruckung in alternierender Reihenfolge. Das Verfahren kann so gewählt werden, daß die Magazine nach jeweils erfolgter Entnahme einer Vielzahl an Kartonzuschnitten verschoben werden. Damit lassen sich alternierend Kartons mit jeweils mehreren gleichartig bedruckten Kartons hintereinander erzeugen. Beispielsweise können einheitlich bedruckte Reihen von Kartons in einem Sammelbehälter erzeugt werden, wobei benachbarte Reihen unterschiedlich bedruckt sind, wenn die Magazine nach jeweils erfolgter Vielzahl an Kartonzuschnitten verschoben wird, und diese Vielzahl der Anzahl an Kartons pro Kartonreihe in einem Sammelbehälter entspricht. Entspricht die Vielzahl der Anzahl an Kartons in einem Sammelbehälter (Anspruch 9), so können einzelne Sammelbehälter jeweils mit Kartons gleichen Druckbilds gefüllt werden, und aufeinanderfolgende Sammelbehälter enthalten Kartons mit unterschiedlichem Druckbild. The magazines will be removed after each removal moved, so boxes are alternately with different printing. At the end of The packaging system is thus filled and closed Cardboard boxes with alternating printing. These filled Cartons are created in the order in which they are created were placed in rows in collection containers, for example trays or packed large boxes. Thus, the Collection boxes the boxes of different printing in alternating order. The The method can be chosen so that the magazines according to each removal of a large number of cardboard blanks be moved. This makes it possible to alternate boxes each with several similarly printed boxes generate one after the other. For example, uniform printed rows of boxes in a collection container are generated, with adjacent rows different are printed if the magazines after a large number of cardboard blanks moved will, and this large number of boxes per Row of boxes in a collection container corresponds. Corresponds to the multitude of the number of boxes in a collection container (Claim 9), so individual containers can each filled with boxes of the same printed image, and successive collection containers contain boxes with different print image.

Die Beschickungsvorrichtung kann Kartonzuschnitte an eine Schachtelformvorrichtung weitergeben (Anspruch 11). Dabei gibt das greifende Mittel die Kartonzuschnitte, zum Beispiel über ein Förderband, in Richtung eines Faltarmes weiter. Der Faltarm drückt einen ankommenden Kartonzuschnitt in eine Faltform und formt dabei einen Karton. Nach einer zuvor auf den Kartonzuschnitt aufgebrachten Leimschicht wird der Kartonzuschnitt in der Faltform auch an den geleimten Stellen gepreßt und somit geklebt. Der Faltarm arbeitet dabei taktweise. Nach erfolgter Befüllung des noch offenen Kartons wird dieser schließlich verschlossen und einem Sammelpacker zugeführt.The loading device can cut cardboard to a Pass box forming device (claim 11). Here gives the gripping agent the cardboard blanks to Example on a conveyor belt, in the direction of a folding arm continue. The folding arm pushes an incoming one Cardboard cut into a folding form and thereby forms one Carton. After a cut to the box beforehand applied layer of glue is the cardboard blank in the Folded form also pressed on the glued areas and thus glued. The folding arm works intermittently. After Once the open carton has been filled, it will be filled finally sealed and fed to a case packer.

Das greifende Mittel kann Kartonzuschnitte auch in Richtung eines herkömmlichen Kartonaufrichters weitergeben (Anspruch 12).The gripping agent can also cut carton blanks in the direction pass on a conventional case erector (claim 12).

Im folgenden werden die Erfindungen in einem Ausführungsbeispiel anhand von Figuren näher beschrieben. Es zeigt:

Die Beschickungsvorrichtung 1 hat zwei Magazine 2, 3 mit darin gestapelten Kartonzuschnitten 4, 5 (Figur 1). An einem Magazin 2 liegt ein auf das Magazin 2 zu und von diesem weg bewegliches, greifendes Mittel 6 an. Das greifende Mittel 6 greift einen Kartonzuschnitt 4 aus dem Magazin 2 und gibt diesen Kartonzuschnitt 4 weiter an ein Förderband 7 (Figur 3). Über das Förderband 7 wird der Kartonzuschnitt 4 unter einer Beleimungseinrichtung 8 vorbeigeführt. Aus den Düsen 9 der Beleimungseinrichtung 8 abgegebener Leim benetzt dabei die linienförmigen Bereiche des Kartonzuschnitts 5, die verleimt werden sollen. Das Förderband 7 fördert den Kartonzuschnitt 4 weiter an eine Faltform 10, wo der beleimte Kartonzuschnitt sodann mittels eines Faltarmes 11 in die Faltform 10 gedrückt wird. Dabei wird der Kartonzuschnitt 4 zu einem verklebten Karton 12 geformt. Der Anpreßdruck des Faltarmes 11 in der Faltform 10 wird sowohl zum Verformen bzw. Knicken des Kartonzuschnitts 4, als auch zum Anpressen der zu verleimenden Flächen des Kartonzuschnitts 4 benötigt. Nach dem Verlassen der als Schachtelformvorrichtung 13 wirkenden Faltform 10 wird der Karton 12 befüllt, verschlossen und schließlich einem Sammelbehälter zugeführt.The loading device 1 has two magazines 2, 3 with cardboard blanks 4, 5 stacked therein (FIG. 1). On a magazine 2 lies towards and from the magazine 2 this moving, gripping means 6. The gripping means 6 grips a cardboard blank 4 from the Magazine 2 and passes this cardboard blank 4 on to Conveyor belt 7 (Figure 3). Via the conveyor belt 7 Cardboard blank 4 under a gluing device 8 passed by. From the nozzles 9 of the gluing device 8 The glue released wets the linear areas the cardboard blank 5, which are to be glued. The Conveyor belt 7 conveys the cardboard blank 4 to one Folding form 10, where the glued cardboard blank then by means of a folding arm 11 is pressed into the folding form 10. Here the cardboard blank 4 becomes a glued cardboard 12 shaped. The contact pressure of the folding arm 11 in the folded form 10 is used both for deforming or buckling the Carton blank 4, as well as for pressing on gluing surfaces of the cardboard blank 4 required. After leaving the one acting as box forming device 13 Folded form 10, the box 12 is filled, closed and finally fed to a collection container.

Nach einem vom greifenden Mittel 6 aus dem einen Magazin 2 entnommenen Kartonzuschnitt 4 wird das andere Magazin 3 an das greifende Mittel 6 herangeschoben (Figur 2), damit jeweils abwechselnd aus den beiden Magazinen 2, 3 Kartonzuschnitte 4, 5 entnommen werden. Jedes der beiden Magazine 2, 3 enthält einen Stapel Kartonzuschnitte 4, 5 mit einheitlichem Druckbild auf dem Kartonzuschnitt 4, 5. Das eine Magazin 2 enthält aber Kartonzuschnitte 4 mit einem anderen Druckbild als die Kartonzuschnitte 5 des Magazins 3. Infolge der abwechselnden Entnahme des greifenden Mittels 6 aus den Magazinen 2, 3 werden abwechselnd Kartonzuschnitte 4 und Kartonzuschnitte 5 weitergegeben, die schließlich zu abwechselnd bedruckten, gefüllten und verschlossenen Kartons 12 führen, welche in dieser Reihenfolge in Sammelbehälter gepackt werden.According to one of the gripping means 6 from the one magazine 2 removed cardboard blank 4, the other magazine 3 the gripping means 6 pushed up (Figure 2), so alternately from the two magazines 2, 3 Cardboard blanks 4, 5 are removed. Each of the two Magazine 2, 3 contains a stack of cardboard blanks 4, 5 with a uniform print image on the cardboard blank 4, 5. One magazine 2 contains cardboard blanks 4 a different print image than the cardboard blanks 5 of the Magazine 3. As a result of the alternate removal of the engaging means 6 from the magazines 2, 3 alternating cardboard blanks 4 and cardboard blanks 5 passed on, which eventually printed alternately, filled and sealed cartons 12, which in be packed in this order in the container.

Die Magazine 2, 3 sind starr miteinander verbunden (Figur 1, Figur 2). Sie werden entlang einer eine gerade Strecke 14 bildenden Stange 15 verschoben. Die Strecke 14 verläuft dabei in einem rechten Winkel zu der Bewegungsrichtung des die Kartonzuschnitte 4, 5 greifenden Mittels 6.The magazines 2, 3 are rigidly connected to one another (FIG 1, Figure 2). You will be along a straight route 14 forming rod 15 moved. Route 14 runs thereby at a right angle to the direction of movement of the the cardboard blanks 4, 5 engaging means 6.

Die Magazine 2, 3 sind über die Stange 15 auf einer Kugelrollbuchse 16 gelagert. Damit ist eine Verschiebung der Magazine 2, 3 unter geringer Reibungskraft möglich. Als Antrieb 17 für die Magazine 2, 3 ist ein pneumatischer Zylinder 18 vorgesehen.The magazines 2, 3 are on the rod 15 on one Ball roller bushing 16 mounted. This is a shift of magazines 2, 3 possible with low friction. As Drive 17 for magazines 2, 3 is a pneumatic one Cylinder 18 provided.

An dem greifenden Mittel 6 ist ein Saugnapf 19 angebracht, der mittels Unterdruck einen Kartonzuschnitt 4, 5 greift und aus einem Magazin 2, 3 entnimmt (Figur 3). Der Saugnapf 19 ist über eine Rohrleitung 20 mit einer Vakuumquelle 21 verbunden. Der Unterdruck der Vakuumquelle 21 ist zu dem Saugnapf 19 zu- und abschaltbar. Über eine andere Rohrleitung 22 ist der Saugnapf 19 zusätzlich mit einer Druckluftquelle 23 verbunden. Der Überdruck der Druckluftquelle 23 ist ebenfalls zu dem Saugnapf 19 zuführbar bzw. kann zu dem Saugnapf 19 hin unterbrochen werden. Das greifende Mittel 6 arbeitet derart, daß es taktweise bei jedem Greifvorgang zuerst mit der Vakuumquelle 21 verbunden ist und dabei einen Kartonzuschnitt 4, 5 mittels Unterdruck greift. Danach wird der Kartonzuschnitt 4, 5 durch eine Schwenkbewegung des Hebels 24 um das Gelenk 25 zum Förderband 7 hin geschwenkt. Am Förderband 7 wird der Kartonzuschnitt 4, 5 durch Unterbindung des Unterdrucks und Aufbringung von Druckluft vom Saugnapf 19 abgestoßen. Anschließend wird der Kartonzuschnitt 4, 5 vom Förderband 7 weitertransportiert und der Hebel 24 zurückgeschwenkt, um einen neuen Kartonzuschnitt 4, 5 zu greifen. A suction cup 19 is attached to the gripping means 6, who grips a cardboard blank 4, 5 by means of negative pressure and takes from a magazine 2, 3 (Figure 3). The suction cup 19 is connected to a vacuum source 21 via a pipeline 20 connected. The vacuum of the vacuum source 21 is too Suction cup 19 can be switched on and off. Another one Pipeline 22 is the suction cup 19 with an additional Compressed air source 23 connected. The overpressure of the Compressed air source 23 is also to suction cup 19 feedable or can be interrupted towards the suction cup 19 will. The gripping means 6 works in such a way that it cyclically with each gripping process first with the vacuum source 21 is connected and thereby a cardboard blank 4, 5 engages by means of negative pressure. Then the cardboard blank 4, 5 by a pivoting movement of the lever 24 around the joint 25 is pivoted towards the conveyor belt 7. On the conveyor belt 7, the cardboard blank 4, 5 by preventing the Vacuum and application of compressed air from the suction cup 19 repelled. Then the cardboard blank 4, 5 from Conveyor belt 7 transported further and the lever 24 pivoted back, to grip a new cardboard blank 4, 5.

Die Beschickungsvorrichtung 1 kann auf verschiedene Art und Weise betrieben werden. Zur Erzeugung einer Reihe von Kartons 12 mit wechselnder Bedruckung bei jeweils zwei dicht hintereinander gefertigten Kartons 12 werden die Magazine 2, 3 direkt nach jeweils einer erfolgten Entnahme eines Kartonzuschnitts verschoben. Zur Erzeugung von jeweils einer Vielzahl Kartons 12 mit gleicher Bedruckung und der anschließenden Erzeugung der gleichen Vielzahl Kartons 12 mit anderer Bedruckung wird die Beschickungsvorrichtung für die dieser Vielzahl entsprechenden Anzahl an Entnahmen von Kartonzuschnitten 4, 5 in der in Figur 1 dargestellten Position belassen und anschließend in eine Position analog Figur 2 verschoben, in welcher die Beschickungsvorrichtung 1 für die gleiche Anzahl an Entnahmen verbleibt. Entspricht diese Anzahl der Anzahl der Kartons 12 in einer Kartonreihe eines Sammelbehälters oder sogar der insgesamt sich in einem Sammelbehälter befindlichen Kartons 12, so können reihenweise gleichartige Kartons 12 einem Sammelbehälter zugeführt werden und somit Reihen unterschiedlich bedruckter Kartons 12 im Sammelbehälter erzeugt werden, oder aber ein Sammelbehälter kann mit nur mit einem Druckbild versehenen Kartons 12 gefüllt werden, wobei aufeinanderfolgende Sammelbehälter Kartons 12 mit unterschiedlichem Druckbild enthalten.The loading device 1 can in various ways and Operated in a manner. To generate a series of Cardboard boxes 12 with alternating printing on two Cartons 12 produced in close succession are the Magazines 2, 3 immediately after each removal of a cardboard blank shifted. To generate each a large number of boxes 12 with the same printing and then generating the same plurality Cardboard boxes 12 with different printing will be the loading device for the number corresponding to this multitude on removal of cardboard blanks 4, 5 in the in FIG Leave position shown and then in a Position shifted analogous to Figure 2, in which the Feeder 1 for the same number Withdrawals remain. This number corresponds to the number of Cardboard boxes 12 in a cardboard row of a collecting container or even the whole itself in a collection container located cartons 12, rows of the same type Cartons 12 are fed to a collection container and thus Rows of differently printed boxes 12 in Collection containers are generated, or a collection container can only be provided with boxes 12 be filled, with successive collection containers Contain boxes 12 with different printed images.
