Description

Die Erfindung betrifft ein Verfahren zum Aufbrechen und Belüften von blattartigen Materialstapeln, insbesondere von Papierstapeln, bei dem die Blattbogen einzelner Lagen des Materialstapels in ihrer Lage zueinander verschoben werden und anschließend abgelegt werden.The invention relates to a method for breaking up and aerating sheet-like material stacks, in particular of paper stacks, in which the sheet sheets of individual layers of the material stack are shifted relative to each other and subsequently deposited.

Die Erfindung betrifft des Weiteren eine Vorrichtung zum Aufbrechen und Belüften von blattartigen Materialstapeln, insbesondere von Papierstapeln, wenigstens bestehend aus Mitteln zum Lösen der Blattbogen jeweils einer Lage des Materialstapels voneinander und Belüften der Lage vor deren Ablegen und Fördermitteln zum Transport der Lage auf eine Ablegevorrichtung.The invention further relates to a device for breaking up and aerating sheet-like material stacks, in particular of paper stacks, at least consisting of means for releasing the sheet sheets each one layer of the material stack from each other and aerating the layer before depositing and funding to transport the layer to a depositing device.

Für die Weiterverarbeitung von insbesondere bedruckten Papierstapeln beispielsweise in einer Schneidemaschine, um große Lagen in kleinere Nutzen zu zerschneiden oder um beispielsweise bei der Herstellung von Büchern die Ränder zu bearbeiten, müssen die Blattbögen der Lagen zueinander genau ausgerichtet werden. Üblich ist der Einsatz von Rüttelvorrichtungen, in denen eine zweiseitige Ausrichtung der Lagen erfolgt. Damit das Ausrichten in der Rüttelvorrichtung beschleunigt werden kann, werden die Lagen vorher - in der Regel von Hand - durchgewölbt, um Luft zwischen die Blattbogen zu bringen und sie voneinander zu trennen.For the further processing of particularly printed stacks of paper, for example in a cutting machine, in order to cut large layers into smaller ones or, for example, to machine the edges in the production of books, the sheet forms of the layers must be exactly one another be aligned. Usual is the use of vibrators in which a two-sided alignment of the layers takes place. To speed up the alignment in the vibrator, the layers are previously arched, usually by hand, to bring air between the sheets and separate them.

Aus der Druckschrift DE 32 19 693.8 ist eine Vorrichtung zur Bildung von verarbeitungsfähigen Teilstapeln aus Folienbogen, insbesondere Papierbogen bekannt, mit der ein automatisches Auffächern ermöglicht werden soll. Die Vorrichtung besteht dabei im Wesentlichen aus einem Förderer, der die Lagen von einem Vorratsstapel auf den Tisch einer Rüttelvorrichtung befördert. Er weist ein umlaufendes Unterband und eine Auffächerungsstation auf, in der eine angetriebene Unterwalze und eine angetriebene Oberwalze angeordnet sind, die einen veränderbaren Durchtrittspalt für die Lagen bilden. Die Umfangsgeschwindigkeiten beider Walzen sind dabei unterschiedlich eingestellt.From the publication DE 32 19 693.8 is a device for the formation of workable sub-stacks of film sheet, in particular paper sheet known, with which an automatic fanning is to be made possible. The device consists essentially of a conveyor that conveys the layers of a supply stack on the table of a vibrating device. It has a circulating sub-belt and a fuzzing station in which a driven lower roller and a driven upper roller are arranged, which form a variable passage gap for the layers. The peripheral speeds of both rollers are set differently.

Wenn die Lage durch die Auffächerungsstation getrieben wird, erfolgt eine gegenseitige Verschiebung zwischen den Blattbogen der Lage. Durch die unterschiedlich eingestellten Umfangsgeschwindigkeiten der Walzen wird die Auffächerung noch verstärkt.As the ply is driven through the fuzz station, there is a mutual shift between the sheet sheets of ply. Due to the differently set peripheral speeds of the rollers, the fanning is enhanced.

Zusätzlich wird mittels Luftdüsen, die am Abgabeende des Förderers angeordnet sind, Luft zwischen die einzelnen Blattbogen geblasen.In addition, air is blown between the individual sheet sheets by means of air nozzles which are arranged at the delivery end of the conveyor.

Diese Vorrichtung ist konstruktiv aufwändig und in der Praxis nicht vorteilhaft einsetzbar, da die Blattbogen der Lagen während der Förderung derart verschoben werden, dass sie knittern.This device is structurally complex and can not be used advantageously in practice, since the sheet of sheets of the layers be moved during the promotion so that they wrinkle.

Es ist deshalb Aufgabe der Erfindung, ein Verfahren der eingangs genannten Art so auszubilden, dass es auf einfache und kostengünstige Weise möglich wird, automatisch eine solche Trennung der Blattbogen einer Lage,voneinander zu erreichen, dass der Rüttelvorgang zeitlich minimiert werden kann.It is therefore an object of the invention to provide a method of the type mentioned in such a way that it is possible in a simple and cost-effective manner, automatically such a separation of the sheet of a sheet to achieve from each other that the shaking can be minimized in time.

Es ist des weiteren Aufgabe der Erfindung, eine Vorrichtung der eingangs beschriebenen Art derart weiter zu entwickeln, dass konstruktiv einfach und automatisch ein sicheres Verschieben der Blattbogen zueinander und ein Belüften der Lagen während des Transports zur und des Auflegens auf die Rüttelvorrichtung möglich wird.It is a further object of the invention to further develop a device of the type described above, that structurally simple and automatic safe movement of the sheet to each other and a venting of the layers during transport to and laying on the vibrator is possible.

Erfindungsgemäß wird die Aufgabe verfahrensseitig durch die Merkmale des Anspruches 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Nach diesem erfindungsgemäßen Verfahren wird auf technologisch einfache Art und Weise ein automatisches Belüften der einzelnen Lagen und ein Verschieben der Blattbogen innerhalb einer jeden Lage erreicht. Dadurch verkürzt sich der nachfolgende Arbeitsgang, das genaue Ausrichten der Lagen, wesentlich. Auch die weiteren Bearbeitungsvorgänge, wie zum Beispiel das Be- und Zerschneiden der Lagen kann optimaler erfolgen, da Stillstandszeiten der Maschinen infolge langwieriger Rüttelvorgänge reduziert werden können.After this process according to the invention is in a technologically simple manner, an automatic venting of the individual layers and moving the leaf arch within each location achieved. This shortens the subsequent operation, the exact alignment of the layers, essential. Also, the other processing operations, such as the cutting and cutting of the layers can be done optimally because downtime of the machine can be reduced due to lengthy shaking.

Außerdem führt der automatisierte Verfahrensablauf zu wesentlichen Arbeitserleichterungen beim Bediener, da dieser große und schwere Papierlagen nicht mehr von Hand dem Vorratsstapel entnehmen und durchwölben muss, um sie zu belüften und die Bogen aufzubrechen.In addition, the automated procedure leads to much easier work for the operator, since he no longer has to manually remove and bulge large and heavy paper layers from the supply stack in order to aerate them and break the sheets.

Nach einer vorzugsweisen Ausgestaltung des erfindungsgemäßen Verfahrens wird die Lage von einer Klemmvorrichtung erfasst und die Klemmvorrichtung zieht die Lage von einem Führungselement schräg nach unten durch den Durchgang. Unmittelbar nach dem Durchlauf der Klemmvorrichtung durch den Durchgang wird das Oberteil der zangenartigen Vorrichtung auf die Lage abgesetzt, so dass sich beim weiteren Durchlauf der Lage die einzelnen Blätter voneinander lösen können. Die Lage wird sodann auf die Ablegevorrichtung abgelegt.According to a preferred embodiment of the method according to the invention, the position of a clamping device is detected and the clamping device pulls the position of a guide element obliquely down through the passage. Immediately after the passage of the clamping device through the passage, the upper part of the pincer-like device is placed on the position, so that the individual sheets can separate from each other during the further passage of the situation. The layer is then deposited on the depositing device.

Die Klemmvorrichtung gewährleistet einerseits, dass sich die Blattbogen zueinander verschieben, andererseits dient sie als Transport- und Haltemittel.On the one hand, the clamping device ensures that the sheet-like sheets move relative to one another, on the other hand, it serves as transport and holding means.

Verfahrensgemäß ist vorgesehen, dass die Größe des Durchganges variabel gestaltet werden und an die Größe der eingesetzten Klemmvorrichtung angepasst werden kann. Dadurch, dass die Klemmvorrichtung durch den Durchgang hindurch die Lage ergreifen kann, wird ermöglicht, dass keine weiteren Transportmittel zum Transport der Lage zum Durchgang eingesetzt werden müssen. Dies wirkt sich positiv auf die Kosten aus und der Verfahrensablauf wird vereinfacht.According to the method it is provided that the size of the passage can be made variable and can be adapted to the size of the clamping device used. Characterized in that the clamping device take through the passage through the situation , it is possible that no further means of transport must be used to transport the layer to the passage. This has a positive effect on the costs and the procedure is simplified.

Von Vorteil kann es auch sein, wenn Lagen im beidseitig fixierten Zustand auf die Ablegevorrichtung abgelegt werden und während des unmittelbaren Ablegvorganges oder erst danach die Fixierung gelöst wird.It may also be advantageous if layers are stored in the fixed state on both sides of the depositing device and during the immediate Ablegvorganges or only after the fixation is released.

Einerseits wird die Lage von der Klemmvorrichtung gehalten, andererseits vom Ober- und Unterteil der zangenartigen Vorrichtung. Damit kann verhindert werden, dass die Blattbogen während des Ablegevorganges ungewollt wieder aneinander haften.On the one hand the layer is held by the clamping device, on the other hand by the upper and lower part of the tong-like device. This can be prevented that the sheets of sheet accidentally adhere to each other again during the deposition process.

Nach einer weiteren Ausgestaltung des erfindungsgemäßen Verfahrens wird die Lage nach der Förderung durch den Durchgang der zangenartigen Vorrichtung in aufgefächerter Form abgelegt.According to a further embodiment of the method according to the invention, the layer is deposited in a fanned-out form after being conveyed through the passage of the tong-like device.

Auch in dieser Form kann die Lage auf vorteilhafte Art beispielsweise einer Rüttelmaschine zugeführt und in dieser in genaue Lage der einzelnen Blattbogen zueinander gebracht werden.Also in this form, the location can be supplied in an advantageous manner, for example, a vibrating machine and placed in this exact location of the individual sheet sheets to each other.

Erfindungsgemäß ist des Weiteren vorgesehen, dass wenigstens das Ober- oder das Unterteil der zangenartigen Vorrichtung angetrieben wird.According to the invention it is further provided that at least the upper or the lower part of the forceps-like device is driven.

Dies dient dem Transport einer nicht fixierten Lage zur Ablegevorrichtung.This serves to transport a non-fixed position to the depositing device.

Von Vorteil ist auch, wenn die Lage vom Materialstapel mittels einer Greifereinheit ergriffen und zum Führungselement oder über das Führungselement zum Durchgang transportiert wird.It is also advantageous if the layer is gripped by the material stack by means of a gripper unit and transported to the guide element or via the guide element for passage.

Damit kann das Verfahren zum Aufbrechen und Belüften von blattartigen Materialstapeln völlig automatisiert erfolgen, was Zeitersparnis und Arbeitserleichterung zur Folge hat.Thus, the process for breaking up and aerating sheet material stacks can be done completely automated, resulting in time savings and work easier.

Die erfindungsgemäße Aufgabe wird des weiteren anordnungsseitig durch die Merkmale des Anspruches 6 gelöst.The object of the invention is further resolved on the arrangement side by the features of claim 6.

Die erfindungsgemäße Vorrichtung zum Aufbrechen und Belüften von blattartigen Materialstapeln ist konstruktiv einfach aufgebaut und gestattet ein schnelles Verschieben und Trennen der Blattbogen einer Lage. Mit dem konstruktiven Aufbau der Vorrichtung wird erreicht, dass sich die Blattbogen bis zum Auflegen auf die Auflegeeinheit nicht wieder aneinander anlegen können. Somit kann das genaue Ausrichten der Lagen beispielsweise in einer Rüttelmaschine innerhalb kurzer Zeit erfolgen.The inventive device for breaking up and aerating sheet-like material stacks is structurally simple and allows a fast moving and separating the sheet of a sheet sheet. With the structural design of the device is achieved that the sheets do not rest against each other until they hang up on the laying unit can. Thus, the exact alignment of the layers can be done for example in a vibrating machine within a short time.

Nach einer vorteilhaften und konstruktiv einfachen Ausführungsform der erfindungsgemäßen Vorrichtung ist das Führungselement und das Unterteil der zangenartigen Vorrichtung walzenartig ausgebildet.According to an advantageous and structurally simple embodiment of the device according to the invention, the guide element and the lower part of the tong-like device is formed like a roller.

Dadurch erhält die Lage, die auf dem Unterteil aufliegend gefördert wird und auf der das obere walzenförmige Element abgesetzt ist eine wellenartige Form, die zum Verschieben der Blattbogen innerhalb der Lage führt.As a result, the layer, which is supported on the lower part and on which the upper roller-shaped element is discontinued, receives a wave-like shape, which leads to displacement of the sheet sheets within the layer.

Erfindungsgemäß ist vorgesehen, dass Ober- und Unterteil der zangenartigen Vorrichtung parallel übereinander angeordnet und gegensinnig umlaufend ausgebildet sind.According to the invention, it is provided that upper and lower part of the pincer-like device are arranged in parallel one above the other and are designed to revolve in opposite directions.

Dadurch wird der Verschiebevorgang der Blattbogen innerhalb der Lage ebenfalls unterstützt.As a result, the movement of the sheet sheet is also supported within the situation.

Das Unterteil kann je nach konkreter konstruktiver Ausführung auf vorteilhafte Art und Weise beispielsweise auch bandartig ausgebildet sein.Depending on the specific structural design, the lower part may advantageously also be designed in a band-like manner, for example.

Wenn das Unterteil einen größeren Durchmesser aufweist als das Oberteil und aus einem weicheren Material besteht, wird der Vorgang des Lösens der Blattbogen einer Lage voneinander unterstützt.If the lower part has a larger diameter than the upper part and consists of a softer material, the process of releasing the sheet sheets of a layer from each other is supported.

Erfindungsgemäß ist vorteilhaft auch vorgesehen, dass wenigstens das Ober- oder das Unterteil einen Antrieb besitzt und dass beide Teile unterschiedliche Umlaufgeschwindigkeiten aufweisen.According to the invention is also advantageously provided that at least the upper or the lower part has a drive and that both Parts have different rotational speeds.

Diese erfindungsgemäße Ausbildung der Vorrichtung unterstützt und verstärkt das Aufblättern der Blattbogen innerhalb einer Lage und somit das Belüften der Lage.This inventive design of the device supports and enhances the leafing of the sheet sheets within a layer and thus the aeration of the situation.

Wenn das Unterteil mit einer Beschichtung versehen ist oder aus einem Material besteht, die bzw. das eine elastische und weichere Oberfläche als die Lage aufweist, werden Beschädigungen durch zu hohe Druckkräfte an der Lage beziehungsweise an den Blattbogen verhindert.If the lower part is provided with a coating or consists of a material which has an elastic and softer surface than the layer, damage is prevented by excessive pressure forces on the sheet or on the sheet sheet.

Eine weitere erfindungsgemäße Ausführungsform sieht vor, dass die Klemmvorrichtung als Klemmzange ausgebildet und derart verfahrbar ist, dass sie nach einseitiger Klemmung der Lage diese über das Führungselement zum und durch den Durchgang hindurch zu der Ablegevorrichtung zieht und dort ablegt.A further embodiment of the invention provides that the clamping device is designed as a clamping pliers and is movable so that it pulls on one-sided clamping of the position on the guide element to and through the passage to the depositing device and stores there.

Damit wird erreicht, dass die ursprüngliche Form der Lage der Blattbogen zueinander im Wesentlichen erhalten bleibt und sich nachfolgende Vorgänge zur Positionierung der gestapelten Lagen zueinander verkürzen.This ensures that the original shape of the position of the sheet sheets to each other is substantially maintained and shorten subsequent operations for positioning the stacked layers to each other.

Erfindungsgemäß ist des Weiteren vorgesehen, dass die Ablegevorrichtung eine Rüttelmaschine ist und dass die Vorrichtung mit der Rüttelmaschine eine Einheit bildet.According to the invention, it is further provided that the depositing device is a vibrating machine and that the device forms a unit with the vibrating machine.

Wichtig ist, dass der Weg zwischen der Aufbrech- und Belüftungsvorrichtung möglichst kurz ist, damit insbesondere dicke und schwere Blattbogen vor dem Ablegen nicht wieder aneinanderhaften können, was zur Folge hätte, dass der Rüttel- oder Positionierungsprozess erschwert würde oder diese Prozesse nicht qualitätsgerecht ausführbar sein könnten. Nachfolgende Schneidvorgänge könnten dann ebenfalls nur mit minderer Qualität ausgeführt werden. Deshalb ist es vorteilhaft, wenn beide Vorrichtungen eine Einheit bilden.It is important that the path between the break-open and ventilation device is as short as possible, so that in particular thick and heavy sheet sheets can not stick together again before depositing, with the result that the Rüttel- or positioning process would be difficult or these processes could not be executed in a quality-appropriate manner. Subsequent cutting operations could then also be carried out only with inferior quality. Therefore, it is advantageous if both devices form a unit.

Zur Unterstützung des Aufbrechvorganges der Lagen ist des Weiteren vorgesehen, dass an der zangenartigen Vorrichtung wenigstens eine Luftdüse angeordnet ist, die zusätzlich Luft zwischen die einzelnen Blattbogen der Lage bläst.To support the Aufbrechvorganges the layers is further provided that at least one air nozzle is arranged on the forceps-like device, which blows additional air between the sheet sheets of the sheet.

Zur Arbeitserleichterung und zur vollautomatischen Durchführung des Verfahrens ist vorgesehen, dass zum Transport der Lage vom Materialstapel zum Führungselement oder über das Führungselement zum Durchgang eine Greifereinheit angeordnet ist.To facilitate work and for fully automatic implementation of the method, it is provided that a gripper unit is arranged for transporting the layer from the material stack to the guide element or via the guide element for passage.

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles, bei dem die erfindungsgemäße Vorrichtung mit einem Rüttelautomaten eine Einheit bildet, näher erläutert werden. Die zugehörige Zeichnung zeigt dabei in

The invention will be explained in more detail with reference to an embodiment in which the device according to the invention with a jogger forms a unit. The accompanying drawing shows in
Fig. 1
a sectional view of the vibrator with inventive device and clamping device for one-sided fixation of the situation in side view and
Fig. 2 to 5
the schematic representation of the individual process steps after the clamping of a layer.

Nach Fig. 1 besteht die erfindungsgemäße Vorrichtung zum Aufbrechen und Belüften von blattartigen Materialstapeln 1, insbesondere von Papierstapeln, im Wesentlichen aus einer Hubplattform 2, auf der der Materialstapel 1, hier in Form eines in einer Schneidemaschine zu beschneidenden Papierstapels, liegt und die vertikal verstellbar ausgebildet ist, der Vorrichtung 3 und des damit verbundenen Rüttelautomaten 4.According to FIG. 1, the device according to the invention for breaking up and aerating sheet-like material stacks 1, in particular of paper stacks, consists essentially of a lifting platform 2, on which the material stack 1, here in the form of a paper stack to be trimmed in a cutting machine, lies and which is designed to be vertically adjustable, the device 3 and the associated vibrating machine 4.

In der Zeichnung nicht gezeigt ist die Greifereinheit, die den Transport einer jeden Lage 5 des Papierstapels 1 zum Führungselement 6 beziehungsweise den Transport über die Führungswalze 6 zum Durchgang 7 der zangenartigen Vorrichtung 8, ausgebildet als Walzenzange, übernimmt.Not shown in the drawing is the gripper unit, which takes over the transport of each layer 5 of the paper stack 1 to the guide element 6 and the transport via the guide roller 6 to the passage 7 of the pliers-like device 8, designed as a roller pliers.

Das Führungselement 6 ist als Einlaufwalze ausgebildet, die um ihre Längsachse drehbar angeordnet und vertikal verfahrbar ist. Dadurch können unterschiedliche Grammaturen der Lagen 5 angepasst und der Abstand zum Ober- und Unterteil 10, 11 der Walzenzange 8 eingestellt werden.The guide element 6 is formed as an inlet roller, which is arranged rotatably about its longitudinal axis and vertically movable. As a result, different grammages of the layers 5 can be adjusted and the distance to the upper and lower parts 10, 11 of the roll tongs 8 can be adjusted.

Die einzelnen Lagen 5 werden mittels einer Abstecheinheit 9 vom Papierstapel 1 abgehoben und von der Greifereinheit erfasst und transportiert.The individual layers 5 are lifted off the paper stack 1 by means of a cutting unit 9 and are detected and transported by the gripper unit.

Die zangenartige Vorrichtung 8 besteht aus zwei in einem Gestell angeordneten, parallel und abstandsweise übereinander befestigten Teilen, dem walzenartigen Oberteil 10, das vertikal verfahrbar und um seine Längsachse drehbar ausgebildet ist, und dem ebenfalls walzenartig und um seine Längsachse drehbar ausgebildeten Unterteil 11, dessen Drehrichtung der Drehrichtung des Oberteils 10 gegenläufig ist. Die zangenartige Vorrichtung 8 ist mit einem vorgegebenen Abstand zum Führungselement 6 angeordnet. Das Unterteil 11 weist außerdem einen solchen vertikalen Abstand zum Führungselement 6 auf, dass die Lage 5, die den Durchgang 7 durchläuft, vom Führungselement 6 kommend, unter einem vorgegebenen Winkel schräg nach unten befördert werden muss.The forceps-like device 8 consists of two arranged in a frame, parallel and spaced superimposed parts, the roller-like upper part 10 which is vertically movable and rotatable about its longitudinal axis, and the likewise cylindrical and rotatable about its longitudinal axis formed lower part 11, the direction of rotation the direction of rotation of the upper part 10 is in opposite directions. The pincer-like device 8 is arranged at a predetermined distance from the guide element 6. The lower part 11 also has such a vertical distance to the guide member 6, that the layer 5, which passes through the passage 7, from the guide member 6 coming, must be transported obliquely down at a predetermined angle.

In der Zeichnung weisen Ober- und Unterteil 10, 11 einen gleichgroßen Durchmesser auf. Um die Auffächerung der Lage zu unterstützen kann es jedoch vorteilhaft sein, wenn das Unterteil 11 einen größeren Durchmesser als das Oberteil 10 aufweist. Außerdem sollte das Unterteil 11 aus einem elastischen und weicheren Material hergestellt sein oder zumindest eine elastische Oberfläche aufweisen, damit Beschädigungen an der Lage vermieden werden. Die Oberfläche des Unterteils muss aus den gleichen Gründen gleitende Eigenschaften aufweisen.In the drawing, upper and lower parts 10, 11 have an equal diameter. In order to support the fanning of the situation, however, it may be advantageous if the lower part 11 has a larger diameter than the upper part 10. In addition, the lower part 11 should be made of an elastic and softer material or at least have an elastic surface, so that damage to the situation can be avoided. The surface of the base must have sliding properties for the same reasons.

Im Ausführungsbeispiel ist für den Transport der Lage 5 vom Führungselement 6 durch den Durchgang 7 zur als Rüttelautomat ausgebildeten Ablegevorrichtung 4 eine Klemmvorrichtung 12 vorgesehen.In the exemplary embodiment, a clamping device 12 is provided for the transport of the layer 5 from the guide element 6 through the passage 7 to the depositing device 4 designed as a vibrating machine.

DE 32 19 693 A1 beschreibt die bekannte Klemmvorrichtung 12 zur Aufnahme einer Lage 5 durch die Klemmzange 13, die auch erfindungsgemäß eingesetzt werden soll. Daher wird dieser Teil der Vorrichtung nicht weiter erläutert. DE 32 19 693 A1 describes the known clamping device 12 for receiving a layer 5 by the clamping forceps 13, which is also to be used according to the invention. Therefore, this part of the device will not be explained further.

Ebenso sind Rüttelautomaten 4 an sich bekannt, so dass auch diese hier nicht näher beschrieben werden.Likewise, vibrators 4 are known per se, so that they are not described here in detail.

Zur Unterstützung des Lösungsvorganges der einzelnen Blattbogen 14 einer Lage 5 voneinander ist im Bereich des Unterteils 11 eine Luftdüse (in der Zeichnung nicht dargestellt) angeordnet, die zur Unterstützung der Bogentrennung zusätzlich Luft zwischen die Blattbogen 14 bläst.To assist the solution process of the individual sheet sheets 14 a layer 5 from each other in the region of the lower part 11 an air nozzle (not shown in the drawing) is arranged, which blows additional air to support the sheet separation between the sheet sheets 14.

Der Verfahrensablauf und die Funktionsweise der Vorrichtung zum Aufbrechen und Belüften von Papierstapeln wird im Folgenden anhand der Figuren 2 bis 6 beschrieben.The method sequence and the mode of operation of the device for breaking up and aerating paper stacks will be described below with reference to FIGS. 2 to 6.

Die Hubplattform 2 bringt den Papierstapel 1, der aus großflächigen, bedruckten einzelnen Blattbogen 14 besteht, durch vertikales Verfahren in eine Position, in der die Abstecheinheit 9 zunächst eine Lage 5 anheben, die Greifereinheit die Lage 5 ergreifen und auf dem Führungselement 6 ablegen kann. Die Klemmzange 13 fährt durch den Durchgang 7 der Walzenzange 8 und fixiert die Lage 5 einseitig.The lifting platform 2 brings the paper stack 1, which consists of large, printed single sheet of sheets 14 by vertical process in a position in which the Abstecheinheit 9 first lift a layer 5, the gripper unit can take the layer 5 and place on the guide member 6. The clamping jaw 13 moves through the passage 7 of the roll tongs 8 and fixes the layer 5 on one side.

Nach dem Erfassen und Klemmen der Lage 5 durch die Klemmzange 13 wird die Lage 5 über die Biegewalze 6 in Richtung des abstandsweise und unterhalb der Biegewalze 6 angeordneten Unterteils 11 der Walzenzange 8 gezogen. Dabei erhält die Lage 5 eine wellenartige Form. Die Lage 5 wird schräg nach unten gezogen. Dadurch können Beschädigungen der Blattbogen 14 vermieden werden.After detecting and clamping the layer 5 by the clamping jaw 13, the layer 5 is pulled over the bending roller 6 in the direction of the distance and below the bending roller 6 arranged lower part 11 of the roll tongs 8. The layer 5 is given a wave-like shape. The layer 5 is pulled obliquely downwards. As a result, damage to the sheet sheets 14 can be avoided.

Das Oberteil 10 der Walzenzange 8 ist vertikal verfahrbar ausgebildet und wird - sobald die Klemmzange 13 den Durchgang 7 zwischen Ober- und Unterteil 10, 11 wieder passiert hat - auf die Lage 5 abgesetzt. Dadurch wird erreicht, dass die Blattbogen 14 der Lage 5 in ihrer Position zueinander verschoben werden. Gleichzeitig werden die einzelnen Blattbogen 14 voneinander getrennt und belüftet. Je weiter die Lage 5 durch den Durchgang 7 gezogen wird, umso größer wird der Abstand zwischen den einzelnen Blattbogen 14 der Lage 5.The upper part 10 of the roll tongs 8 is designed to be vertically movable and is - as soon as the clamping tongs 13 the passage 7 between the upper and lower part 10, 11 has again passed - deposited on the layer 5. This ensures that the sheet sheets 14 of the layer 5 are shifted in position to each other. At the same time, the individual sheet sheets 14 are separated from each other and ventilated. The further the layer 5 is pulled through the passage 7, the greater the distance between the individual sheet sheets 14 of the layer 5.

Dadurch, dass Ober- und Unterteil 10, 11 gegenläufig gedreht werden, wird ein weiteres Verschieben der Blattbogen 14 zueinander erreicht.Characterized in that the upper and lower parts 10, 11 are rotated in opposite directions, a further displacement of the sheet sheets 14 to each other reached.

Die Walzenzange 8 ist so angeordnet, dass die Lage 5 nach dem Durchlauf des Durchganges 7 direkt auf den Rütteltisch 15 des Rüttelautomaten 4 abgelegt wird.The roller pliers 8 is arranged so that the layer 5 is deposited directly after the passage of the passage 7 on the vibrating table 15 of the vibrator 4.

Möglich ist auch, die Walzenzange 8 horizontal verfahrbar auszubilden, so dass sie in eine vorgegebene Position über den Rütteltisch 15 mitgeführt werden kann.It is also possible to form the roll tongs 8 horizontally movable, so that they can be carried in a predetermined position on the vibrating table 15.

Die Fig. 2 bis 5 veranschaulichen die einzelnen Verfahrensstufen beziehungsweise Fördervorgänge.FIGS. 2 to 5 illustrate the individual process stages or conveying processes.

Fig. 2 zeigt die Klemmung der Lage 5 durch die Klemmzange 13.Fig. 2 shows the clamping of the layer 5 by the clamping pliers 13th

Fig. 3 veranschaulicht den Ziehvorgang der Lage 5 mittels Klemmzange 13 über die Biegewalze 6 in Richtung des Unterteils 11 der Walzenzange 8. Dabei wird die Klemmzange 13 sowohl horizontal als auch vertikal verfahren. Der oberste Blattbogen 14 verbleibt in seiner Position, während die anderen Blattbogen 14 zueinander verschoben werden.Fig. 3 illustrates the drawing process of the layer 5 by means of clamping pliers 13 via the bending roller 6 in the direction of the lower part 11 of the roller pliers 8. The clamping pliers 13 is moved both horizontally and vertically. The uppermost sheet 14 remains in position while the other sheets 14 are displaced relative to each other.

Fig. 4 stellt dar, dass das Oberteil 10 auf die Lage 5 aufgesetzt worden ist, was die Verschiebung der Blattbogen 14 zueinander bewirkt und eine Rückpositionierung der Blattbogen 14 der Lage 5 zueinander verhindert. Die gegensinnige Drehrichtung von Ober- und Unterteil 10, 11 unterstützt den Verschiebevorgang. Das stetige Befördern der Lage 5 durch die Walzenzange 8 unter einseitiger Fixierung bewirkt das Trennen der Blattbogen 14 voneinander und das Belüften der Lage 5. Sie ist nach Ablage im Rüttelautomaten schnell und genau ausrichtbar.Fig. 4 shows that the upper part 10 has been placed on the layer 5, which causes the displacement of the sheet sheets 14 to each other and prevents repositioning of the sheet sheets 14 of the layer 5 to each other. The opposite direction of rotation of the upper and lower part 10, 11 supports the sliding operation. The steady conveyance of the layer 5 by the roll tongs 8 under one-sided fixation causes the separation of the sheet sheets 14 from each other and the aeration of the layer 5. It is quickly and accurately aligned after filing in the vibrator.

Um Beschädigungen insbesondere der Blattbogen 14 zu vermeiden, die unmittelbar am Ober- oder Unterteil 10, 11 anliegen, ist vorgesehen, dass wenigstens das Unterteil 11 mit einer elastischen Beschichtung versehen ist, die weicher als die Lage 5 ist.In order to avoid damage, in particular the sheet sheet 14, which bear directly on the upper or lower part 10, 11, it is provided that at least the lower part 11 is provided with an elastic coating which is softer than the layer 5.

Insbesondere beim Aufbrechen und Belüften von Lagen 5 kleinen Formats ist es möglich, auf den Einsatz der Klemmvorrichtung 12 vollständig zu verzichten und Ober- und/oder Unterteil 10, 11 der der Walzenzange 8 angetrieben auszubilden. Die Lagen 5 werden mittels Greifereinheit über die Biegewalze 1 zum Durchgang 7 geführt und von dort beispielsweise zum Rüttelautomaten 4 gefördert, wobei es ebenfalls zur Verschiebung und Trennung der Blattbogen 5 kommt. Das Auflegen auf dem Rütteltisch 15 geschieht in diesem Fall in aufgefächerter Form.In particular, when breaking up and ventilating layers 5 small format, it is possible to completely dispense with the use of the clamping device 12 and upper and / or lower part 10, 11 of the roll tongs 8 driven form. The layers 5 are guided by means of gripper unit on the bending roller 1 to the passage 7 and promoted from there, for example, to the vibrator 4, which also comes to the displacement and separation of the sheet sheet 5. The laying on the vibrating table 15 happens in this case in fanned out form.

Eine Kombination beider Vorrichtungen und Verfahren, das heißt, ein teilweiser Einsatz der Klemmvorrichtung 12 beispielsweise, um die Lage 5 zur Walzenzange 8 zu fördern, könnte für bestimmte Einsatzfälle auch vorteilhaft anwendbar sein.A combination of both devices and methods, that is, a partial use of the clamping device 12, for example, to promote the layer 5 to the roll tongs 8, could also be advantageously used for certain applications.

Selbstverständlich ist der Einsatz der erfindungsgemäßen Vorrichtung auch separat, das heißt, ohne direkte Anbindung an einen Rüttelautomaten 4, möglich.Of course, the use of the device according to the invention also separately, that is, without direct connection to a vibrator 4, possible.
