Die Erfindung betrifft eine Vorrichtung zur Bildung mehrerer nebeneinander angeordneter Produktstapel aus einem einlaufenden Produktstrom aus Papierbögen oder dergleichen, umfassend einen Ablagebereich zur Aufnahme der einlaufenden Papierbögen oder dergleichen und Bildung abtransportfähiger Produktstapel, mindestens ein Trennelement für jeden Produktstapel zur Bildung eines Spalts zwischen einem jeweils abtransportfähigen Produktstapel und nachfolgend einlaufenden Papierbögen oder dergleichen sowie Mittel zum Auspressen von Lufteinschlüssen aus den abtransportfähigen Produktstapeln. Des weiteren betrifft die Erfindung ein Verfahren zum Bilden mehrerer nebeneinander angeordneter Produktstapel aus einem einlaufenden Produktstrom aus Papierbögen oder dergleichen, umfassend die Schritte: Sammeln und Stapeln der einlaufenden Papierbögen oder dergleichen in einem Ablagebereich, wobei mehrere Produktstapel zeitgleich nebeneinander gebildet werden, Trennen der abtransportfähigen Produktstapel von einlaufenden Papierbögen oder dergleichen durch Bildung eines Spaltes zwischen einem jeweils abtransportfähigen Produktstapel und nachfolgend einlaufenden Papierbögen oder dergleichen mittels Trennelementen, Auspressen von Lufteinschlüssen aus den abtransportfähigen Produktstapeln mittels geeigneter Mittel.The invention relates to a device for forming a plurality of side by side arranged product stack from an incoming product stream of paper sheets or The like, comprising a storage area for receiving the incoming Paper sheets or the like and formation of transportable product stacks, at least one separating element for each product stack to form a gap between a product stack that can be transported away in each case and subsequently arriving Paper sheets or the like and means for squeezing air inclusions the transportable product stacks. Furthermore, the invention relates to a Method for forming a plurality of juxtaposed product stacks from one incoming product stream of paper sheets or the like comprising the steps of: Collecting and stacking the incoming paper sheets or the like in one Filing area, where several product stacks are formed side by side at the same time, Separate the transportable product stacks of incoming paper sheets or The like by forming a gap between each removable Product stack and subsequently incoming paper sheets or the like by means of Separating elements, squeezing air bubbles from the transportable Product stacks by appropriate means.
Derartige Vorrichtungen und Verfahren kommen insbesondere bei der Herstellung von Stapeln aus Papier, Pappe oder anderen stapelfähigen Materialien, wie z.B. Folien, zu Einsatz. Solche Stapel werden in üblicherweise mehmutzigen Produktionsmaschinen hergestellt. In solchen Produktionsmaschinen werden durch Längs- und/oder Querschneiden von Materialbahnen kontinuierlich sogenannte Riese in Form von Blattlagen oder Blattstapeln gebildet. In einer mehmutzigen Produktionsmaschine liegen mehrere dieser Riese eng nebeneinander und bilden einen Riesstrang. Dieser Riesstrang wird in einer Sammelstation, beispielsweise dem Ablagebereich, abgelegt. Mittels geeigneter Mittel, zweckmäßigerweise einem Zangensystem, wird der Riesstrang auf eine Vorrichtung zum Fördern der Riese quer zu ihrer Antransportrichtung gezogen bzw. auf dieser abgesetzt.Such devices and methods are used in particular in the production of Stacking of paper, paperboard or other stackable materials, e.g. Slides, too Commitment. Such stacks are usually in mehmutzigen production machines produced. In such production machines are by longitudinal and / or Cross cutting of material webs continuously so-called giant in the form of Leaf layers or stacks of leaves formed. In a mehmutzigen production machine several of these giant are close together and form a Riesstrang. This Riesstrang is stored in a collection station, for example, the storage area. By suitable means, expediently a pliers system, the Riesstrang on a device for conveying the giant across her Antransportrichtung pulled or deposed on this.
Die einzelnen Blätter, die den einlaufenden Produktstrom darstellen, fallen frei in den Ablagebereich, so daß sich in jedem Stapel zwischen den einzelnen Blättern Luft bzw. Lufteinschlüsse befinden. Diese Lufteinschlüsse führen beim Weitertransport der Stapel dazu, daß einzelne Blätter eines Stapels insbesondere beim Beschleunigen der Stapel verrutschen können. Um diesen Effekt zu vermeiden, ist es bekannt, die Lufteinschlüsse aus den Stapeln auszupressen. Hierzu weisen bekannte Vorrichtungen eine einzelne Walze auf, die sich quer zu Antransportrichtung über alle nebeneinander liegende Stapel eines im Ablagebereich befindlichen Riesstranges erstreckt. Mit anderen Worten drückt die Walze gleichzeitig auf alle Stapel eines Riesstranges, während die Stapel mittels des Zangensystems relativ zur Walze bewegt werden.The individual leaves, which represent the incoming product flow, fall freely into the Storage area, so that in each stack between the individual sheets of air or Air pockets are located. These air pockets lead to the further transport of the stack in that individual sheets of a stack, in particular when accelerating the stack can slip. To avoid this effect, it is known the air pockets to squeeze out of the stacks. For this purpose, known devices have a single Roll on, which is transverse to Antransportrichtung over all adjacent stacks a Rieserstranges located in the storage area extends. In other words expresses the roll at the same time on all stacks of a Rieserstranges, while the stacks by means of Pliers system are moved relative to the roller.
Diese bekannte Ausbildung weist jedoch den Nachteil auf, daß sie konstruktiv sehr aufwendig und damit kostenintensiv ist. Ein weiterer Nachteil besteht darin, daß die genannten Vorrichtungen bzw. Mittel zum Auspressen der Lufteinschlüsse schwer oder gar nicht an bestehende Vorrichtungen nachrüstbar sind, da der oftmals nur in geringem Maße vorhandene Bauraum für derartige Mittel nicht ausreicht.However, this known training has the disadvantage that it is very constructive consuming and therefore expensive. Another disadvantage is that the said devices or means for squeezing the air pockets difficult or can not be retrofitted to existing devices, as often only in small Dimensions available space for such means is insufficient.
Es ist daher Aufgabe der vorliegenden Erfindung, eine leicht handhabbare und kompakte Vorrichtung zu schaffen, die einerseits zuverlässig das Auspressen von Lufteinschlüssen aus Stapeln von Papierbögen oder dergleichen gewährleistet und andererseits kostengünstig herstellbar ist. Des weiteren ist es Aufgabe der vorliegenden Erfindung, ein einfaches und kostengünstiges Verfahren zum Auspressen von Lufteinschlüssen aus Stapeln von Papierbögen oder dergleichen vorzuschlagen.It is therefore an object of the present invention, an easy to handle and to create a compact device, on the one hand reliable the pressing of Ensures air pockets from stacks of paper sheets or the like and on the other hand is inexpensive to produce. Furthermore, it is the task of the present Invention, a simple and inexpensive method for pressing of To suggest air inclusions from stacks of paper sheets or the like.
Diese Aufgabe wird durch eine Vorrichtung der eingangs genannten Art dadurch gelöst, daß das Mittel zum Auspressen von Lufteinschlüssen aus den abtransportfähigen Produktstapeln aus mehreren Einzelelementen besteht, wobei jedem Trennelement ein Einzelelement zugeordnet ist. Dadurch wird eine besonders kompakte Vorrichtung geschaffen, die auch leicht an bestehenden Vorrichtungen nachrüstbar ist. Durch die Aufteilung des Mittels in mehrere Einzelkomponenten ist eine besonders zuverlässige Entlüftung sämtlicher Stapel eines Riesstranges gewährleistet, da jeder Stapel individuell mit Druck beaufschlagbar ist. Des weiteren ist die erfindungsgemäße Vorrichtung besonders kostengünstig herstellbar, da die Trennelemente ohnehin mit allen erforderlichen Freiheitsgraden, nämlich Dreh-, Schwenk- und Bewegungsachsen, in der Vorrichtung existieren, so daß auch eine Nachrüstung besonders einfach und günstig realisierbar ist.This object is achieved by a device of the type mentioned, characterized that the means for squeezing air inclusions from the transportable Product stacks consists of several individual elements, with each separator a Individual element is assigned. This will be a particularly compact device created, which is also easy to retrofit to existing devices. By the Distribution of the agent into several individual components is a particularly reliable Venting all the stacks of a Rieserstranges guaranteed as each stack individually pressurizable. Furthermore, the invention is Device particularly inexpensive to produce, since the separating elements anyway all required degrees of freedom, namely rotation, pivoting and moving axes, exist in the device, so that a retrofit particularly simple and is low feasible.
Vorteilhafterweise ist jeder Trennfinger als Bestandteil des Trennelementes schwenkbar um eine Drehachse ausgebildet, wobei der Trennfinger federbelastet ist. Dies ermöglicht auf besonders einfache und zuverlässige Weise den Ausgleich von Höhenunterschieden nebeneinander angeordneter und einem Riesstrang angehörender Stapel. Dadurch wird ein Verrutschen einzelner Bögen eines Stapels beim Beschleunigen auf einem dem Ablagebereich nachgeordneten Querförderer verhindert.Advantageously, each separating finger is pivotable as part of the separating element formed about an axis of rotation, wherein the separating finger is spring-loaded. this makes possible in a particularly simple and reliable way the compensation of height differences juxtaposed and a Riesstrang belonging stack. This will a slipping of individual sheets of a stack when accelerating on a Storage area downstream cross conveyor prevented.
In einer bevorzugten Weiterbildung der Erfindung ragt jedes Einzelelement zum Auspressen von Lufteinschlüssen senkrecht zur Transportebene in Richtung der Transportebene über den Trennfinger hinaus. Dadurch wird vermieden, daß der Trennfinger in einer abgesenkten Position auf dem obersten Bogen eines abtransportfähigen Stapels aufliegt und durch Scheuern Markierungen verursacht. Die Qualität der abtransportfähigen Stapel ist demnach verbessert.In a preferred development of the invention, each individual element protrudes Squeezing air inclusions perpendicular to the transport plane in the direction of Transport plane beyond the release finger. This avoids that the Separating finger in a lowered position on the topmost arc of a removable stack rests and caused by rubbing marks. The The quality of the removable stack is therefore improved.
Des weiteren wird die Aufgabe durch ein Verfahren mit den eingangs genannten Schritten dadurch gelöst, daß das Auspressen der Lufteinschlüsse für jeden Produktstapel separat erfolgt. Durch dieses individuelle Entlüften jedes einzelnen Stapels eines Riesstranges ist das Verrutschen einzelner Bögen eines Stapels besonders wirksam verhindert.Furthermore, the object is achieved by a method with the aforementioned Steps solved in that the squeezing of the air pockets for each Product stack done separately. By this individual venting each one Stack of a Riesstranges is the slipping of individual bows of a pile especially effectively prevented.

Drehachse 28 ausgebildet. Der Trennfinger 19 ist optional ebenfalls federbelastet, wobei
ein Federelement 29 einerseits am Trennhebel 18 und andererseits am Trennfinger 19
derart befestigt ist, daß der Trennfinger 19 mittels der Federkraft entgegen dem
Uhrzeigersinn um die Drehachse 28 schwenkbar ist. Die Schwenkbewegung ist jedoch
durch einen Anschlag 30 begrenzbar, wobei der Anschlag 30 aus einer
Anschlagposition in eine Freigabeposition und umgekehrt bringbar ist. Der Trennfinger
19 ist im wesentlichen L-förmig ausgebildet. An einem langen Schenkel 31 ist das
Einzelelement 20 angeordnet. Der kurze Schenkel 32 ist zum freien Ende hin spitz
zulaufend, also quasi rampenförmig, geformt, um das Einlaufen bzw. Auflaufen des
einlaufenden Produktstroms 12 zu erleichtern.At a
Jedes der Einzelelemente 20 zum Auspressen von Lufteinschlüssen umfaßt mindestens
eine Andrückrolle und/oder ein Bürstenelement. Das Einzelelement 20 kann aber auch
aus zwei oder mehreren gleichen oder unterschiedlichen Elementen zum Andrücken
bzw. Pressen bestehen. Auch können mehrere Einzelelemente 20 einem Trennelement
15 bzw. jedem Trennfinger 19 zugeordnet sein. Andere feststehende oder rotierende
Andrück- bzw. Preßelemente sind ebenfalls einsetzbar. In nicht gezeigten
Ausführungsformen können die Einzelelemente 20 z.B. auch als plattenförmige
Andrückelemente ausgebildet sein, die jeweils über einen Hohlraum verfügen. Derartige
Andrückelemente sind in dem Hohlraum mit Druckluft beaufschlagbar. Durch
Öffnungen auf der dem Stapel zugewandten Seite des Andrückelementes kann die
Druckluft entweichen, so daß quasi berührungsloser Druck auf den Stapel aufbringbar
ist, um die Lufteinschlüsse innerhalb des Stapels auszupressen.Each of the
Jedes Einzelelement 20 ist fest mit dem Trennelement 15 bzw. genauer mit dem
Trennfinger 19 verbunden. Das bedeutet, daß jede Bewegung in linearer sowie
rotierender Richtung des Trennfingers 19 in gleicher Weise vom Einzelelement 20
ausgeführt wird. Das Einzelelement 20 ist im Bereich des langen Schenkels 31 an
diesem vorzugsweise lösbar befestigt. Die Lage bzw. Position des Einzelelementes 20
zum langen Schenkel 31 ist derart gewählt, daß das Einzelelement 20 senkrecht zur
Transportebene E (siehe Figuren 3 und 4, Ebene E ist aufgespannt durch die
Koordinaten X und Z) in Richtung derselben über den Schenkel 31 hinausragt, so daß
beim Absenken des Trennelementes 15 auf den abtransportfähigen Produktstapel 11 als
erstes das Einzelelement 20 auf dem Produktstapel 11 aufsetzt. In Antransportrichtung
(Pfeil A) des Produktstroms 12 ist das Einzelelement 20 hinter dem Schenkel 31
angeordnet.Each
In einer weiteren nicht explizit dargestellten Ausführungsform muß das Einzelelement
20 nicht am Trennelement 15 bzw. am Trennfinger 19 angeordnet sein. Vielmehr kann
das Einzelelement 20 selbständig gelagert sein. Beispielsweise kann das Einzelelement
20 an einem eigenen (nicht dargestellten) Hebel auf der Welle 22 um die Drehachse 21
schwenkbar sein. In dieser Ausführungsform ist dann z.B. jedem Trennelement 15
benachbart ein Hebel mit dem daran angeordneten Einzelelement 20 zugeordnet. Jedem
Trennelement 15 können auch mehrere Einzelelemente 20, beispielsweise zu beiden
Seiten zugeordnet sein. Die Trennung von Trennelement 15 einerseits und Hebel mit
Einzelelement 20 andererseits hat den Vorteil, daß z.B. im Falle eines Defektes der
Austausch der fehlerhaften Teile bzw. die Wartung derselben vereinfacht ist. Des
weiteren läßt sich der Anpreßdruck der Einzelelemente 20 dann unabhängig vom
Trennelement 15 einstellen.In another embodiment not explicitly shown, the
Im folgenden wird das Verfahren anhand der Figurenfolge 6 a bis f näher erläutert.
Die aus einer Materialbahn geschnittenen Papierbögen 13 werden im Ablagebereich 14,
z.B. in einer Sammelbox, gesammelt. Nachdem beim Sammeln die zuvor definierte
Zählung von üblicherweise 500 Blatt erreicht ist, senkt sich das Trennelement 15 ab, so
daß der kurze Schenkel 32 des Trennfingers 19 auf dem obersten Blatt des
Produktstapels 11 aufliegt (siehe Figur 6a). Zu diesem Zeitpunkt steht ein Greifmittel,
z.B. ein Zangensystem 33 vor dem Ablagebereich 14. Die Einzelelemente 20 jedes
Trennelementes 15 stehen in Antransportrichtung gemäß Pfeil A hinter dem
abtransportfähigen Produktstapel 11 über. Im nächsten Schritt gemäß Figur 6b greift das
Zangensystem 33 den Produktstapel 11 (auch Paket genannt). Damit das Zangensystem
33 zuverlässig greifen kann, wird das Trennelement 15 hierfür durch Schwenken
angehoben, so daß zwischen Trennelement 15 und Produktstapel 11 kein Kontakt
besteht. Anschließend zieht das Zangensystem 33 den Produktstapel 11 aus dem
Ablagebereich 14. Die zeitgleich und kontinuierlich einlaufenden Papierbögen 13 liegen
auf dem kurzen Schenkel 32 des Trennfingers 19 auf. Während der Produktstapel 11 aus
dem Ablagebereich 14 gezogen wird, wird gleichzeitig mit gleicher Geschwindigkeit
ein Rechen 34 nachgeführt, um die einlaufenden und zunächst nur auf dem Trennfinger
19 abgestützten Papierbögen 13 zu unterstützen (siehe Figur 6c). Wenn der
Produktstapel 11 mindestens teilweise aus dem Ablagebereich 14 gezogen ist, senkt sich
das Trennelement 15 wieder ab, so daß das über den Trennfinger 19 hinausragende
Einzelelement 20 auf dem obersten Blatt des Produktstapels 11 aufsetzt (siehe Figur
6d). Der Produktstapel 11 wird weiter unter dem Einzelelement 20 weggezogen,
wodurch die im Produktstapel 11 befindlichen Lufteinschlüsse ausgepreßt werden. Das
Einzelelement 20 verhindert gleichzeitig, daß der Trennfinger 19 selbst auf dem
Produktstapel 11 aufliegt, so daß ein Scheuern oder dergleichen verhindert wird, indem
ein Spalt 35 zwischen Trennfinger 19 und Produktstapel 11 gebildet ist (siehe
insbesondere Figur 2). In Figur 6e erreicht der Rechen 34 seine Endposition vor dem
Trennfinger 19. Nachdem der Produktstapel 11 vollständig unter dem Einzelelement 20
weggezogen wurde (siehe Figur 6f), fällt das Trennelement 15 mit seinem Trennfinger
19 auf das Niveau des Rechens 34 ab.In the following, the method is explained in more detail with reference to the sequence of figures 6 a to f.
The
Das Verfahren wurde am Beispiel eines einzelnen Produktstapels 11 mit einem
einzelnen Trennelement 15 beschrieben. In der Praxis liegen aber mehrere
Produktstapel 11 nebeneinander, wobei jedem Produktstapel 11 dann ein oder mehrere
Trennelemente 15 zugeordnet sind.The method was the example of a
Die Vorrichtungen und das Verfahren wurden am Beispiel der Entlüftung von Produktstapeln aus Papierbögen beschrieben. Es sind jedoch jegliche Art stapelfähiger Produkte, wie zum Beispiel Stapel aus Pappbögen, Folien oder dergleichen mit der Vorrichtung und dem Verfahren zu entlüften.The devices and the method were exemplified by the venting of Product stacks of paper sheets described. However, there are any kind stackable Products, such as piles of cardboard sheets, films or the like with the Device and the process to vent.
