Abstract

The method involves holding a sheet (3) at a leading edge, and discarding the sheet by releasing from the holding. The discarded sheet is moved again subsequently to the edge and brought and further forwarded into a hanging position. The sheet is removed for a reorientation from the horizontal position into the hanging position in a sheet support (3). The sheet is further processed during the conveyance in the hanging position. An independent claim is also included for a device for transporting a sheet that is laid-out by a sheet processing machine.

Description

Die Erfindung liegt auf dem Gebiete von Transport und Weiterverarbeitung von Druckprodukten. Die Erfindung betrifft ein Verfahren und eine Vorrichtung nach den Oberbegriffen der entsprechenden, unabhängigen Patentansprüche. Verfahren und Vorrichtung dienen dem Weitertransport und gegebenenfalls der Weiterverarbeitung von Bogen, die von einer bogenverarbeitenden Maschine, insbesondere von einer Bogendruckmaschine (z.B. Bogenoffsetdruckmaschine) ausgelegt werden.The invention is in the field of transport and further processing of printed products. The invention relates to a method and a device according to the preambles of the corresponding independent claims. Method and apparatus are used for onward transport and optionally further processing of sheets which are laid out by a sheet-processing machine, in particular by a sheet-fed printing machine (for example sheet-fed offset printing press).

Bogenverarbeitende Druckmaschinen sind bekannterweise mit einer Auslageeinrichtung ausgestattet, die üblicherweise einen umlaufenden Auslageförderer mit einer Mehrzahl von hintereinander umlaufenden Greifern und eine Stapelvorrichtung aufweist. Der Auslageförderer schliesst an den letzten bogentransportierenden Zylinder des letzten Druckwerkes oder eines auf das letzte Druckwerk folgenden Nachbehandlungswerks (z.B. Lackwerk) an, wobei jeder Greifer des Auslagförderers einen von diesem Zylinder zugeführten Bogen an seiner vorlaufenden, quer zur Förderrichtung ausgerichteten Kante erfasst und über die Stapelvorrichtung transportiert, wo der Bogen vom Greifer entlassen und auf einer Stapelauflage oder auf einem auf der Stapelauflage liegenden Bogenstapel niedergelegt wird. Gegebenenfalls wird der Bogen, bevor er sich in der Stapelvorrichtung niederlegt, von einer Bogenbremse abgebremst.Sheet-fed printing machines are known to be equipped with a delivery device, which usually has a rotating delivery conveyor with a plurality of successively rotating grippers and a stacking device. The delivery conveyor adjoins the last sheet-transporting cylinder of the last printing unit or a post-treatment plant following the last printing unit (eg coating unit), each gripper of the delivery conveyor detecting a sheet supplied by this cylinder at its leading edge oriented transversely to the conveying direction and via the stacking device transported where the sheet is released from the gripper and placed on a stack support or on a stack of sheets lying on the pile stack. If necessary, the Bow, before it settles in the stacking device, braked by a sheet brake.

Die Stapelvorrichtung der Auslageeinrichtung weist üblicherweise eine Stapelauflage (z.B. Palette, deren Tragfläche Nuten aufweist) und eine Hilfsstapelauflage (z.B. Rechen mit Gitterstäben, die in die Nuten der Palette passen) auf, wobei Stapelauflage und Hilfsstapelauflage in vertikaler Richtung verschiebbar sind, derart, dass ihre Höhenposition an die Höhe des entstehenden Stapels anpassbar ist. Die Hilfsstapelauflage wird über einem auf der Stapelauflage abgelegten Stapel in die Stapelvorrichtung geschoben (üblicherweise in der Förderrichtung des Auslageförderers), wenn der auf der Stapelauflage aufliegende Stapel eine vorgegebene Höhe aufweist. Während weitere Bogen auf der Hilfsstapelauflage abgelegt werden, wird der auf der Stapelauflage aufliegende Stapel samt dieser Stapelauflage beispielsweise mit Hilfe eines Hubstaplers aus der Stapelvorrichtung entfernt und eine neue Stapelauflage wird in der Stapelvorrichtung positioniert und unter die Hilfsstapelauflage gefahren, die dann aus der Stapelposition weggezogen wird. Der Weitertransport und auch eine weitere Verarbeitung der gestapelten Bogen erfolgt off-line.The stacking device of the delivery device usually has a stack support (eg pallet whose support surface has grooves) and an auxiliary stack support (eg rake with bars that fit into the grooves of the pallet), wherein stack support and auxiliary stack support are displaced in the vertical direction, such that their Height position is adaptable to the height of the resulting stack. The auxiliary stacking support is pushed over a stack deposited on the stack support into the stacking device (usually in the conveying direction of the delivery conveyor) when the stack lying on the stack support has a predetermined height. While further sheets are being deposited on the auxiliary stack support, the stack resting on the stack support including this stack support is removed from the stack apparatus, for example with the aid of a lift truck, and a new stack support is positioned in the stack apparatus and driven under the auxiliary stack support, which is then pulled away from the stack position , The further transport and further processing of the stacked sheets takes place off-line.

In vielen Fällen sind die Bogen bzw. Druckfarben oder Lacke auf den Bogen unmittelbar nach dem Verlassen des letzten Druckwerks oder Nachbehandlungswerks nicht derart vollständig trocken oder ausgehärtet, dass die Bogen, ohne miteinander zu verkleben, aufeinander gestapelt oder, ohne zu verschmieren, von stationären Vorrichtungsteilen geführt werden können. Aus diesem Grunde wird beispielsweise vorgeschlagen, zwischen stationären Vorrichtungsteilen und den zu transportierenden Bogen und gegebenenfalls auch zwischen benachbarten solchen Bogen durch entsprechende Zufuhr von Druckluft Luftkissen zu erstellen und/oder zwischen letztem Druckwerk oder Nachbehandlungswerk Hilfsvorrichtungen vorzusehen, die der Trocknung oder Aushärtung der Druckfarben oder Lacke dienen.In many cases, the sheets or inks or varnishes on the sheet immediately after leaving the last printing unit or aftertreatment are not so completely dry or cured that the sheets, without gluing together, stacked on each other or, without smearing, of stationary device parts can be performed. For this reason, for example, it is proposed to provide between stationary device parts and the sheets to be transported and possibly between adjacent such arc by appropriate supply of compressed air cushion and / or provide between last printing unit or aftertreatment auxiliary devices, the drying or curing of the printing inks or paints serve.

Es ist auch bekannt, die Bogen nicht in einem grösseren Stapel auf der Stapelauflage abzulegen sondern in relativ kleinen Teilstapeln, die durch Teilstapelauflagen voneinander getrennt und übereinander angeordnet sind, wobei durch entsprechende Stützung der Teilstapelauflagen dafür gesorgt wird, dass die Teilstapel in senkrechter Richtung voneinander beabstandet sind. Mit dieser Massnahme wird verhindert, dass der Druck auf die gestapelten Bogen durch eine zu hohe Zahl von darauf abgelegten, weiteren Bogen schnell derart anwächst, dass zwischen den Bogen vorhandene Luft schnell ausgepresst wird und die Bogen unerwünscht stark aneinander gepresst werden. Auch mit dieser Massnahme wird also versucht, ein Aneinanderkleben der gestapelten Bogen zu verhindern.It is also known that the sheets are not stored in a larger stack on the stack support but in relatively small sub-stacks, which are separated by stacking parts and arranged one above the other, is ensured by appropriate support of the stacking partitions that the part stacks in the vertical direction spaced from each other are. This measure prevents the pressure on the stacked sheets from rapidly increasing as a result of an excessively high number of further sheets deposited thereon, so that air present between the sheets is rapidly pressed out and the sheets are undesirably pressed against one another. Even with this measure, therefore, an attempt is made to prevent sticking of the stacked sheets together.

Die Erfindung stellt sich nun die Aufgabe, ein Verfahren und eine Vorrichtung zu schaffen, mit denen von der Auslageeinrichtung einer bogenverarbeitenden Maschine, insbesondere von einer Bogendruckmaschine ausgelegte Bogen weitertransportiert und gegebenenfalls weiterverarbeitet werden können, wobei der Weitertransport und gegebenenfalls die Weiterverarbeitung gemäss Erfindung on-line an die Bogenauslage anschliessen sollen. Dabei sollen das Verfahren und die Vorrichtung gemäss Erfindung auch anwendbar sein für die Übernahme von Bogen mit noch nicht völlig trockener oder noch nicht völlig ausgehärteter Druckfarbe, wobei die Bogen in keiner Weise Schaden nehmen sollen. Verfahren und Vorrichtung gemäss Erfindung sollen aber trotzdem einfach und insbesondere auch bei hoher Stückleistung mit geringen Geschwindigkeiten betreibbar sein.The invention now has the task of providing a method and a device with which from the delivery device of a sheet-processing machine, in particular from a sheetfed press sheet designed to be transported and optionally further processed, the further transport and optionally further processing according to the invention on-line to connect to the sheet delivery. In this case, the method and apparatus according to the invention should also be applicable for the acquisition of sheets with not completely dry or not completely cured ink, the sheets should take no damage. Nevertheless, the method and device according to the invention should be able to be operated at low speeds simply and in particular even at high unit performance.

Diese Aufgabe wird gelöst durch das Verfahren und die Vorrichtung, wie sie in den Patentansprüchen definiert sind.This object is achieved by the method and the device as defined in the claims.

Gemäss Erfindung werden die vom Auslageförderer in an sich bekannter Weise auf einer im wesentlichen horizontalen Bogenauflage abgelegten Bogen von Greifern eines weiterfördernden Greiferförderers erfasst, in eine hängende, das heisst im wesentlichen senkrechte Lage gedreht und in dieser Lage weitertransportiert und gegebenenfalls weiterverarbeitet. Dabei werden die Bogen von den Greifern des Greiferförderers an derselben Kante erfasst, wie sie von den Greifern des Auslageförderers erfasst waren, nämlich an der bei der Auslage vorlaufenden Kante. Von je einem Greifer des Greiferförderers wird je eine Mehrzahl von bis zu ca. 100 Bogen, insbesondere zwischen 50 und 100 Bogen erfasst, wobei diese zusammen erfassten Bogen in einem kleinen Bogenstapel angeordnet sind.According to the invention, the sheets conveyed by the delivery conveyor in a manner known per se are deposited on a substantially horizontal sheet support sheet of grippers detected a further-promoting gripper conveyor, rotated in a hanging, that is, substantially vertical position and further transported in this position and optionally further processed. In this case, the sheets are gripped by the grippers of the gripper conveyor at the same edge, as they were detected by the grippers of the delivery conveyor, namely at the leading edge at the delivery. Each of a gripper of the gripper conveyor per a plurality of up to about 100 sheets, in particular between 50 and 100 sheets is detected, these combined sheets are arranged in a small stack of sheets.

Während der Auslageförderer die Bogen mit etwa derselben Geschwindigkeit fördert wie die bogenverarbeitende Maschine und auch in derselben Anordnung, also hintereinander und mit im wesentlichen in Förderrichtung ausgerichteten Oberflächen, transportiert der weiterfördernde Greiferförderer die Bogen mit gegeneinander gerichteten, beispielsweise quer zur Förderrichtung ausgerichteten Oberflächen und mit relativ kleinen Abständen voneinander. Aus diesem Grunde ist die Fördergeschwindigkeit des Greiferförderers relevant kleiner als die Geschwindigkeit des Auslageförderers, insbesondere auch weil er nicht einzelne Bogen sondern kleine Bogenstapel ergreift und hängend weiter transportiert.While the delivery conveyor conveys the sheets at about the same speed as the sheet processing machine and also in the same arrangement, ie one behind the other and with substantially aligned in the conveying direction surfaces, the weiterfördernde gripper conveyor transports the sheets against each other, for example, aligned transversely to the conveying direction surfaces and relative small distances from each other. For this reason, the conveying speed of the gripper conveyor is relevantly smaller than the speed of the delivery conveyor, in particular because it does not grab single sheet but small stack of sheets and transported hanging.

Werden beispielsweise mit einer Leistung von 5 Bogen pro Sekunde Bogen mit A1-Format quer ausgelegt und in Bogenstapeln zu je 50 Bogen durch den Greiferförderer erfasst und weiter transportiert, wobei die Greifer des Greiferförderers typischerweise einen Abstand von ca. 10 cm voneinander haben, dann muss der Auslageförderer eine Fördergeschwindigkeit von ca. 3 m/s haben, während der Greiferförderer eine Geschwindigkeit von nur ca. 0,01 m/s hat.If, for example, sheets of A1 format are laid out transversely at a rate of 5 sheets per second and are picked up by the gripper conveyor in sheet stacks of 50 sheets and transported further, the grippers of the gripper conveyor typically being at a distance of about 10 cm from one another the delivery conveyor has a conveying speed of approx. 3 m / s, while the gripper conveyor has a speed of only approx. 0.01 m / s.

Für die Drehung der Bogenstapel von einer im wesentlichen horizontalen Lage, in der sie auf der Bogenauflage abgelegt werden, in eine hängende Lage, in der sie an oberen Kanten durch die Greifer des Greiferförderers gehalten weiter transportiert werden, werden die Bogenstapel beispielsweise von der Bogenauflage gezogen, um dann in die hängende Lage gebracht zu werden. Wenn die ausgelegten Bogen bzw. Druckfarben oder Lacke auf diesen Bogen noch nicht völlig getrocknet oder ausgehärtet sind, ist es vorteilhaft oder gar notwendig, dass Relativbewegungen parallel zu den Bogenoberflächen zwischen Bogenauflage und Bogen und auch zwischen benachbarten Bogen verhindert werden. In solchen Fällen wird für die Umorientierung der Bogenstapel von der horizontalen (liegenden) in die vertikale (hängende) Lage vorgeschlagen, die Bogenauflage zusammen mit den Bogen in die hängende bzw. vertikale Lage zu bringen und erst dann quer zu den Bogenstapeln zu distanzieren.For the rotation of the sheet stack from a substantially horizontal position in which they are stored on the sheet support, in a hanging position in the they are kept transported at upper edges by the gripper of the gripper conveyor, the sheet stacks are pulled, for example, from the sheet support, to be then brought into the hanging position. If the laid sheets or inks or varnishes on this sheet are not completely dried or cured, it is advantageous or even necessary that relative movements are prevented parallel to the sheet surfaces between sheet support and sheet and also between adjacent sheets. In such cases, for the reorientation of the sheet stack from the horizontal (horizontal) to the vertical (hanging) position proposed to bring the sheet support together with the sheet in the hanging or vertical position and only then to distance across the sheet stacks.

Es zeigt sich, dass die in den relativ kleinen Bogenstapeln hängend geförderten Bogen einander nicht negativ beeinflussen. Dies rührt insbesondere davon her, dass die Schwerkraft parallel zu den Bogenoberflächen wirkt, die Bogen also nicht gegeneinander presst, und dass die Bogen jedes Stapels durch den Greifer des Greiferförderers relativ zueinander in einer stabilen Anordnung gehalten werden. Da die Geschwindigkeit des Greiferförderers klein ist (siehe weiter oben), bewegt auch der Fahrtwind die frei hängenden Bogenbereiche nicht in unerwünschter Weise relativ zueinander.It turns out that the sheets supported in the relatively small pile of sheets do not adversely affect each other. This is due in particular to the fact that the force of gravity acts in parallel with the sheet surfaces, ie that the sheet is not pressed against one another, and that the sheets of each stack are held in a stable arrangement relative to one another by the gripper of the gripper conveyor. Since the speed of the gripper conveyor is small (see above), the airstream also does not undesirably move the free-hanging arch areas relative to each other.

Zwischen dem Ablegen der Bogen auf der Bogenauflage und der Umorientierung der abgelegten Bogenstapel in die hängende Lage kann die Stapelauflage zusammen mit den darauf positionierten Bogen beispielsweise in vertikaler und/oder horizontaler Richtung verschoben werden, wobei die Bogenstapel vor, während oder nach einer solchen Bewegung von den Greifern des Greiferförderers ergriffen werden.Between the deposition of the sheet on the sheet support and the reorientation of the deposited sheet stack in the hanging position, the stack support can be moved together with the sheet positioned thereon, for example, in the vertical and / or horizontal direction, the sheet stack before, during or after such movement of the grippers of the gripper conveyor are taken.

Weiterverarbeitungsschritte, die während der Förderung durch den Greiferförderer durchführbar sind, sind beispielsweise Trockenen bzw. mit Wärme behandeln, Zwischenlagern, gegebenenfalls kombiniert mit Umorganisieren oder Schneiden. Vorteilhafterweise werden solche Weiterverarbeitungsschritte an den hängend geförderten Bogenstapeln durchgeführt.Further processing steps that can be carried out during conveyance by the gripper conveyor are, for example, dry or heat treat, intermediate storage, optionally combined with reorganization or cutting. Advantageously, such further processing steps are carried out on the suspended conveyed sheet stacks.

Zur Abgabe der Bogenstapel werden diese von den Greifern des Greiferförderers entlassen und beispielsweise an einen weiteren, gegebenenfalls an einer anderen Bogenkante angreifenden Greiferförderer übergeben, in einer Stapelvorrichtung gestapelt oder hintereinander oder einander teilweise überlappen auf einer Förderauflage (z.B. Förderband) abgelegt.To deliver the sheet stacks, they are released by the grippers of the gripper conveyor and, for example, transferred to a further gripper conveyor, optionally stacked on another sheet edge, stacked in a stacking device or placed behind one another or partially overlapping on a conveyor support (e.g.

Die erfindungsgemässe Vorrichtung ist also ausgerüstet für einen Anschluss an einen an sich bekannten Auslageförderer einer bogenverarbeitenden Maschine und weist als Hauptbestandteil einen weiterfördernden Greiferförderer auf, wobei funktionsmässig zwischen Auslageförderer und Greiferförderer eine Bogenauflage angeordnet ist, die zur bogenverarbeitenden Maschine oder zur erfindungsgemässen Vorrichtung gehören kann.The inventive device is thus equipped for connection to a known delivery conveyor a sheet processing machine and has as a main component on a further conveying gripper conveyor, wherein functionally between the delivery conveyor and gripper conveyor a sheet support is arranged, which may belong to the sheet processing machine or the inventive device.

Der Greiferförderer weist, wie dies auch vom Auslageförderer bekannt ist, hintereinander förderbare Greifer auf, die zur Erfassung von quer zur Förderrichtung ausgerichteten Bogenkanten ausgerüstet sind und beispielsweise die Form von zwei gegeneinander pressbaren Leisten haben oder als Greiferreihe ausgestaltet sind, wobei die Leisten oder Greiferreihen vorteilhafterweise etwa so lang sind wie die zu ergreifenden Kanten. Während die Greifer am Auslageförderer in relativ grossen (gegebenenfalls formatabhängigen) und gleichbleibend regelmässigen Abständen voneinander angeordnet sind, sind die Abstände zwischen den Greifern des weiterfördernden Greiferförderers relevant kleiner und können regelmässig und gleichbleibend oder aber auch variierbar und dadurch möglicherweise unregelmässig sein.The gripper conveyor has, as is well known from the delivery conveyor, successively conveyable gripper, which are equipped for detecting aligned transversely to the conveying direction sheet edges and for example have the shape of two mutually pressed strips or configured as a gripper row, the strips or gripper rows advantageously about as long as the edges to be taken. While the grippers are arranged on the delivery conveyor in relatively large (possibly format-dependent) and constantly regular distances from each other, the distances between the grippers of the further conveying gripper conveyor are relevantly smaller and can be regular and consistent or even variable and thus possibly irregular.

Die Bogenauflage ist vorteilhafterweise mindestens abwärts verschiebbar. Vorteilhafterweise ist eine Mehrzahl von Bogenauflagen vorgesehen, die alternierend mit dem Auslageförderer bei der Bogenablage oder mit dem Greiferförderer bei der Bogenergreifung und/oder Bogen-Umorientierung kooperieren oder die abgelegten Bogenstapel von einer Auslageposition in eine Ergreifposition bringen. Die Bogenauflagen laufen dazu vorteilhafterweise hintereinander auf einer Umlaufbahn um und können zusätzlich beispielsweise auf Armen verschiebbar angeordnet sein. Auf diese Weise ist es möglich, bezüglich Geschwindigkeit und Bewegungsform relativ komplexe Umlaufbahnen zu realisieren.The sheet support is advantageously at least downwardly displaceable. Advantageously, a plurality of sheet supports is provided which cooperate alternately with the delivery conveyor in the sheet storage or with the gripper conveyor in the sheet gripping and / or sheet reorientation or bring the stored sheet stack from a delivery position to a gripping position. Advantageously, the sheet supports run in succession on an orbit and may additionally be arranged displaceably on arms, for example. In this way, it is possible to realize relatively complex orbits in terms of speed and motion.

Der weiterfördernde Greiferförderer ist derart angeordnet und gesteuert, dass seine Greifer vom Auslageförderer auf der Bogenauflage ausgelegte Bogen an ihrer bei der Auslage vorlaufenden Kante, das heisst, an der von den Greifern des Auslageförderers entlassenen Kante, ergreifen können, wobei die Bogenauflage zwischen Auslage und Ergreifung gegebenenfalls bewegt wird. Der Greiferförderer bzw. dessen Greifer sind ferner derart angeordnet, ausgebildet und gesteuert, dass sie die ergriffenen Bogen von der Lage, in der sie durch die Bogenauflage in der Ergreifposition gehalten werden (z.B. im wesentlichen horizontale Lage), in eine hängende Lage bringen und in dieser weitertransportieren und gegebenenfalls aus dieser Lage wieder abgeben können. Dazu sind die Greifer des Greiferförderers vorteilhafterweise in der Ebene der Förderrichtung schwenkbar und ist diese Schwenkbarkeit bei der Weiterförderung eine freie Schwenkbarkeit. Der Greiferförderer der erfindungsgemässen Vorrichtung ist dabei derart mit dem Auslageförderer bzw. mit den Bogenauflagen synchronisierbar, dass jeder seiner Greifer eine als kleiner Stapel abgelegte Mehrzahl von ausgelegten Bogen erfasst, in eine hängende Lage bringt und weiter transportiert.The further conveying gripper conveyor is arranged and controlled so that its gripper from the delivery conveyor on the sheet support sheet designed on their leading edge in the delivery edge, that is, at the dismissed by the grippers of the delivery conveyor edge, can take, the sheet support between display and seizure if necessary, is moved. The gripper conveyor or its gripper are further arranged, designed and controlled so that they bring the gripped sheets from the position in which they are held by the sheet support in the gripping position (eg substantially horizontal position) in a suspended position and in transport this further and, where appropriate, relinquish it from this position. For this purpose, the grippers of the gripper conveyor are advantageously pivotable in the plane of the conveying direction and this pivotability in the further promotion of a free pivoting. The gripper conveyor of the device according to the invention is synchronized with the delivery conveyor or with the sheet supports such that each of its grippers detects a plurality of laid-out sheets deposited as a small stack, brings them into a suspended position and transports them further.

Figur 1 zeigt als sehr schematische Seitenansicht eine Vorrichtung gemäss Erfindung anhand der das erfindungsgemässe Verfahren im Detail beschrieben werden soll. Links in der Figur 1 ist der Auslageförderer 1 (schematisch als strichpunktierte Linie dargestellt) einer bogenverarbeitenden Maschine dargestellt. Dieser Auslageförderer 1 ist beispielsweise ein Kettenförderer, an dem in relativ grossen, an das Bogenformat angepassten und regelmässigen Abständen Greifer 2 angeordnet sind. Die Greifer 2 haben vorteilhafterweise quer zur Förderrichtung eine Ausdehnung, die der Länge der zu ergreifenden Bogenkanten etwa entspricht. Die Greifer 2 sind beispielsweise als je eine quer zur Förderrichtung ausgerichtete Greiferreihe ausgestaltet. Der Auslageförderer 1 kooperiert mit einer unter dem Auslageförderer 1 und in einem Abstand zu dessen Greifern 2 angeordneten Bogenauflage 3 derart, dass in an sich bekannter Art durch den Auslageförderer 1 zugeförderte Bogen 4 nacheinander vom Auslageförderer 1 entlassen und auf der Bogenauflage 3 abgelegt werden. Gegebenenfalls wirkt unmittelbar vor dem Ablegen zusätzlich eine Bogenbremse (nicht dargestellt) und während dem Ablegen ein vorderer Bogenanschlag 5 auf die Bogen 4. Gegebenenfalls wird die Bogenauflage während dem Auslegen derart abgesenkt, dass der Abstand zwischen der Bogenauslage bzw. einem auf der Bogenauflage aufliegenden Bogenstapel und den Greifern des Auslagefördereres unabhängig von der Stapelhöhe gleich bleibt. FIG. 1 shows a very schematic side view of a device according to the invention with reference to the inventive method will be described in detail. Left in the FIG. 1 is the delivery conveyor 1 (shown schematically in phantom) represented a sheet processing machine. This delivery conveyor 1 is, for example, a chain conveyor, on which grippers 2 are arranged in relatively large, matched to the sheet format and regular intervals. The gripper 2 advantageously have an extension transverse to the conveying direction, which corresponds approximately to the length of the sheet edges to be taken. The grippers 2 are designed, for example, as one each aligned transversely to the conveying direction gripper row. The delivery conveyor 1 cooperates with a arranged under the delivery conveyor 1 and at a distance to its grippers 2 sheet support 3 that in a conventional manner conveyed by the delivery conveyor 1 sheet 4 successively discharged from the delivery conveyor 1 and stored on the sheet support 3. Optionally, immediately before depositing additionally a sheet brake (not shown) and while depositing a front sheet stop 5 on the sheet 4. If necessary, the sheet support is lowered during laying so that the distance between the sheet delivery or one resting on the sheet support Sheet stack and the grippers of the delivery conveyor regardless of the stack height remains the same.

Wenn auf der Bogenauflage 3 die vorgesehene Zahl von Bogen abgelegt ist, wird sie durch eine weitere Bogenauflage 3' ersetzt. Dazu wird in an sich bekannter Weise die Bogenauslage 3 abwärts verschoben und die weitere Bogenauflage 3' beispielsweise in der Förderrichtung des Auslageförderers 1 darüber geschoben. Mit der Absenkung wird die Bogenauflage 3 auch aus dem Bereich des Bogenanschlags 5 bewegt.If the intended number of sheets is deposited on the sheet support 3, it is replaced by a further sheet support 3 '. For this purpose, the sheet delivery 3 is moved down in a conventional manner and pushed the other sheet support 3 ', for example in the conveying direction of the delivery conveyor 1 above. With the lowering of the sheet support 3 is also moved from the area of the sheet stop 5.

Der weiterfördernde Greiferförderer 6 (schematisch als strichpunktierte Linie dargestellt) ist derart angeordnet und gesteuert, dass seine Greifer 7 beispielsweise von oben auf Vorderkanten der auf der abgesenkten Bogenauflage 3 abgelegten Bogen 4 treffen und diese erfassen können. Damit die Bogenauflage eine solche Erfassung nicht stört, ist ihre Vorderkante wie in Figur 1 dargestellt gegenüber der Vorderkante der abgelegten Bogen 4 etwas zurückversetzt oder die Vorderkante der Bogenauflage 3 weist Lücken auf, durch die hindurch die Teilgreifer einer den Greifer 7 bildenden Greiferreihe gefahren werden können. Damit der Greiferförderer kontinuierlich betrieben werden kann, wird die Bogenauflage 3 vorteilhafterweise mindestens während der Ergreifung mit den Greifern 7 des Greiferförderers 6 derart synchronisiert bewegt, dass Greifer und Auflage eine gleiche Höhe haben. Sobald die Bogen erfasst sind, wird die Bogenauflage 3 beispielsweise parallel zur Förderrichtung des Auslageförderers zurückgezogen, so dass die erfassten Bogen von ihr rutschen und dann eine frei hängende, das heisst senkrechte Lage einnehmen. Um Deformationen der Bogen im Bereich der erfassten Kante zu vermeiden ist der Greifer vorteilhafterweise mindestens im dem Bereich, in dem die Bogen oder Bogenstapel gedreht werden, in der Ebene der Förderrichtung frei schwenkbar und kann sich dadurch an die neue Lage der Bogen oder Bogenstapel anpassen.The weiterfördernde gripper conveyor 6 (shown schematically as a dotted line) is arranged and controlled so that his grippers 7 meet, for example, from above on leading edges of the deposited on the lowered sheet support 3 sheet 4 and can detect them. So that the sheet support does not interfere with such detection, its leading edge is as in FIG. 1 shown opposite the front edge of the deposited sheet 4 set back slightly or the front edge of the sheet support 3 has gaps through which the sub-gripper of a gripper 7 forming gripper row can be driven. So that the gripper conveyor can be operated continuously, the sheet support 3 is advantageously at least synchronized during gripping with the grippers 7 of the gripper conveyor 6 moves so that gripper and support have an equal height. Once the sheets are detected, the sheet support 3 is withdrawn, for example, parallel to the conveying direction of the delivery conveyor, so that the detected sheets slip from it and then assume a free-hanging, that is vertical position. In order to avoid deformation of the sheet in the region of the detected edge of the gripper is advantageously at least in the area in which the sheet or stack of sheets are rotated freely in the plane of the conveying direction and can thereby adapt to the new position of the sheet or sheet stack.

Die in der Figur 1 dargestellte Ausführungsform der Übernahme der Bogen 4 durch die Greifer 7 des Greiferförderers benötigt mindestens zwei Bogenauflagen 3 und 3', weist aber vorteilhafterweise mehr als zwei Bogenauflagen auf, wie dies in der Figur 1 auch dargestellt ist. Je mehr Bogenauflagen zwischen der Position, in der die Bogen ausgelegt werden, und der Position, in der die Bogen von der Bogenauflage getrennt werden, angeordnet sind, desto länger ist die Verweilzeit der Bogen auf den Bogenauflagen. Während dieser Verweilzeit können die Bogen weiter trocknen und können sich die Bogenstapel stabilisieren, dadurch, dass sie kompakter werden durch Abfliessen von Luft zwischen den Bogen. Ob die Bogen oder Bogenstapel früher oder später während einer solchen Verweilzeit von den Greifern 7 des Greiferförderers erfasst werden, kann an die Stabilität der Bogen oder Bogenstapel angepasst werden oder an vorrichtungsseitige Bedingungen.The in the FIG. 1 illustrated embodiment of the acquisition of the sheet 4 by the gripper 7 of the gripper conveyor requires at least two sheet supports 3 and 3 ', but advantageously has more than two sheet supports, as shown in the FIG. 1 is also shown. The more sheet stops are arranged between the position in which the sheets are laid out and the position in which the sheets are separated from the sheet support, the longer is the residence time of the sheets on the sheet supports. During this dwell time, the sheets can continue to dry and can stabilize the sheet stacks by becoming more compact by draining air between the sheets. Whether the sheets or sheet stacks will sooner or later be detected by the grippers 7 of the gripper conveyor during such a dwell time can be adapted to the stability of the sheets or sheet stacks or to equipment-side conditions.

Während der genannten Verweilzeit, in der die Bogenstapel 8 auf den Bogenauflagen 3 aufliegend abwärts bewegt werden, können die Bogenauflagen 3 auch seitlich, das heisst senkrecht zur Papierfläche der Figur 1 bewegt werden, so dass die Ebene der Förderrichtung des Auslageförderers 1 relativ zur Ebene der Förderrichtung des Greiferförderers 6 seitlich verschoben ist. Auf diese Weise bleibt die Stirnseite des Auslageförderers 1 und mindestens der in der Auslgeposition positionierten Stapelauflage 3 von weiteren Vorrichtungsteilen weitgehend frei, so dass in bekannter Weise von dieser Seite durch Personal Probeexemplare entnommen, Trennblätter eingelegt oder andere Arbeiten durchgeführt werden können.During the said residence time, in which the sheet stacks 8 are moved lying on the sheet supports 3 downwards, the sheet supports 3 can also laterally, that is perpendicular to the paper surface of FIG. 1 are moved, so that the plane of the conveying direction of the delivery conveyor 1 is displaced laterally relative to the plane of the conveying direction of the gripper conveyor 6. In this way, the end face of the delivery conveyor 1 and at least positioned in the Auslgeposition stack support 3 remains largely free of other device parts, so that taken in a known manner from this page by staff probes, inserts inserted or other work can be performed.

Da die Bogen für ihre Umorientierung und für den Weitertransport in der Ausführungsform gemäss Figur 1 von der Bogenauflage gezogen werden, eignet sich diese Ausführungsform nicht für Bogen, die (auch nach der oben genannten Verweilzeit) noch zum Verschmieren neigen. Eine weitere Ausführungsform der Übernahme der Bogen 4 durch Greifer 7 des Greiferförderers 6, die sich für den genannten Fall besser eignet, wird im Zusammenhang mit Figur 5 beschrieben.Since the bow for their reorientation and for onward transport in the embodiment according to FIG. 1 are drawn from the sheet support, this embodiment is not suitable for sheets that tend (even after the above residence time) still smearing. Another embodiment of the acquisition of the sheet 4 by gripper 7 of the gripper conveyor 6, which is better suited for the case mentioned, is in connection with FIG. 5 described.

Aus der Figur 1 geht hervor, dass durch entsprechende Synchronisierung von Auslageförderer 1, Bogenauflagen 3 und Greiferförderer 6 verschiedene Zahlen von stapelartig angeordneten Bogen (Bogenstapel 8) von einem Greifer 7 des Greiferförderers 6 ergriffen, umorientiert und weitertransportiert werden kann, ohne dass dafür das Prinzip des Verfahrens oder der Vorrichtung verändert werden müsste.From the FIG. 1 shows that by corresponding synchronization of delivery conveyor 1, sheet supports 3 and gripper conveyor 6 different numbers of stacked sheets (sheet stack 8) grabbed by a gripper 7 of the gripper conveyor 6, reoriented and can be transported without the principle of the method or the Device would have to be changed.

Die vom Greiferförderer 6 in relativ kleinen Abständen (typischerweise ca. 10 cm) voneinander und mit einander zugewandten, im wesentlichen senkrechten Oberflächen, an den oberen Kanten gehalten geförderten Bogenstapel 8 werden beispielsweise durch eine Weiterverarbeitungsstation 10 gefördert. Diese Weiterverarbeitungsstation 10 kann beispielsweise ein Zwischenlager sein, in dem die Bogenstapel gegebenenfalls umorganisiert werden, das heisst ihre Aufeinanderfolge verändert wird, oder es kann eine Trocknungsanlage sein, in der die hängenden Bogen durch Wärme und/oder gezielte Luftströme getrocknet bzw. Druckfarben oder Lacke ausgehärtet werden. Die Weiterverarbeitungsstation 10 kann auch eine Schneidestation sein, in der nicht gehaltene Bogenkanten beschnitten werden.The sheet stacks 8 conveyed by the gripper conveyor 6 at relatively small distances (typically about 10 cm) from one another and facing one another, essentially vertical surfaces, held at the upper edges, are conveyed through a further processing station 10, for example. This further processing station 10 may be, for example, an intermediate storage in which the sheet stacks are optionally reorganized, that is, their succession is changed, or it may be a drying plant in which the hanging sheet dried by heat and / or targeted air currents or cured inks or coatings become. The post-processing station 10 may also be a cutting station in which non-held sheet edges are trimmed.

Nach der Weiterbehandlungsstation 10 werden die beispielsweise immer noch hängend geförderten Bogenstapel 8 vom Greiferförderer 6 entlassen und beispielsweise einander teilweise überlappend auf einer Förderauflage 12 abgelegt.After the further processing station 10, for example, still suspended conveyed sheet stack 8 are released from the gripper conveyor 6 and, for example, partially overlapping each other on a conveyor support 12 stored.

Weitere Beispiele von Weiterbehandlungsstationen und Entlassungen durch den Greiferförderer 6 werden im Zusammenhang mit den Figuren 2 bis 4 angesprochen.Further examples of further treatment stations and discharges by the gripper conveyor 6 are in connection with the FIGS. 2 to 4 addressed.

Figuren 2 und 3 zeigen zwei beispielhafte Einrichtungen, in denen das erfindungsgemässe Verfahren vorteilhafterweise anwendbar ist. Figures 2 and 3 show two exemplary devices in which the inventive method is advantageously applicable.

Gemäss Figur 2 werden die Bogen wiederum vom Auslageförderer 1 einer bogenverarbeitenden Maschine auf eine Bogenauflage 3 ausgelegt und von da in kleinen Stapeln 8 von den Greifern 7 des Greiferförderers 1 übernommen und in eine hängende Lage gebracht. Figur 2 zeigt zwei mögliche Ausführungsformen des Greiferförderers, die mit 6 und 6' bezeichnet sind, wobei es sich beim Förderer 6 um einen Förderer mit äquidistanten Greifern 7 handelt, also beispielsweise um einen entsprechenden Kettenförderer wie der Auslageförderer 1, und beim Förderer 6' um einen Förderer mit Greifern 7', deren Abstände voneinander variierbar sind, also beispielsweise um voneinander unabhängige, greifertragende Förderelemente, die mittels geeigneter Antriebe oder mittels Schwerkraft in einem Führungskanal gefördert werden.According to FIG. 2 The sheets are in turn designed by the delivery conveyor 1 a sheet-processing machine on a sheet support 3 and taken over from there in small stacks 8 of the grippers 7 of the gripper conveyor 1 and placed in a hanging position. FIG. 2 shows two possible embodiments of the gripper conveyor, which are denoted by 6 and 6 ', wherein the conveyor 6 is a conveyor with equidistant grippers 7, so for example to a corresponding chain conveyor as the delivery conveyor 1, and the conveyor 6' to a conveyor with grippers 7 ', whose distances are variable from each other, so for example, to each other independent, gripper-carrying conveying elements, which are conveyed by means of suitable drives or by gravity in a guide channel.

Nach einer Weiterverarbeitung, die im vorliegenden Fall lediglich eine Zwischenlagerung bzw. Zwischenlagerung mit Umorganisation (siehe auch Figur 4) sein kann und die von den Bogenstapeln 8 hängend durchlaufen wird, werden die Bogenstapel 8 vom Greiferförderer 6 oder 6' bzw. von dessen Greifern 7 oder 7' entlassen, beispielsweise wie bereits in Figur 1 gezeigt, als Schuppenstrom auf einer Förderauflage 12 abgelegt, um anschliessend beispielsweise einzeln gefaltet und auf Paletten 13 oder Wickel 14 geladen zu werden. Die Bogenstapel 8 können aber auch in einer Stapelvorrichtung 15 zu grösseren Stapeln aufgeschichtet und in diesen geschnitten werden (Schneidvorrichtung 16), um dann ebenfalls beispielsweise auf Paletten 13 geladen zu werden.After further processing, in the present case, only an intermediate storage or intermediate storage with reorganization (see also FIG. 4 ) and which is traversed by the sheet stacks 8, the sheet stacks 8 are discharged from the gripper conveyor 6 or 6 'or from its grippers 7 or 7', for example as already described in US Pat FIG. 1 shown as a scale flow deposited on a conveyor support 12, to be subsequently folded, for example, individually and loaded on pallets 13 or winding 14. However, the stack of sheets 8 can also be stacked in a stacking device 15 to larger stacks and cut into these (cutting device 16), to then also be loaded, for example, on pallets 13.

Wenn der Greiferförderer 6' mit voneinander unabhängigen, greifertragenden Förderelementen ausgerüstet ist, ist es offensichtlich möglich, die Bogenstapel 8 aus dem Zwischenlager (Weiterverarbeitungsstation 10) nach Bedarf mittels einer Weiche 17 der einen oder anderen Ablage und weiteren Verarbeitung zuzuführen. Wenn der Greiferförderer 6 mit an einer Kette fest angeordneten Greifern 7 ausgestattet ist, ist dies offensichtlich nur durch eine Übergabe an einen anderen Förderer möglich.If the gripper conveyor 6 'is equipped with independent, gripper-carrying conveying elements, it is obviously possible, the sheet stack 8 from the intermediate storage (further processing station 10) as needed by means of a switch 17 of one or the other storage and further processing supply. If the gripper conveyor 6 is equipped with fixedly arranged on a chain grippers 7, this is obviously possible only by a transfer to another conveyor.

Figur 3 zeigt eine ähnliche Einrichtung wie Figur 2. Gleiche Elemente sind daher mit gleichen Bezugsziffern bezeichnet und werden nicht mehr beschrieben. Anstelle der in Figur 2 dargestellten Weiche 17, mit deren Hilfe einzelne greifertragende Förderelemente wahlweise der einen oder anderen Ablage und weiteren Verarbeitung zugeführt werden, wird hier ein Karussell 20 oder eine andere Verschiebungsvorrichtung verwendet, mit der ganze mit solchen Förderelementen gefüllte Kanalstücke 21 rotiert oder anders verschoben werden und dadurch wahlweise an weiterführende Kanäle angeschlossen werden können. Auch für diese Art der Aufteilung des Fördergutes sind voneinander unabhängig förderbare Förderelemente notwendig. FIG. 3 shows a similar device as FIG. 2 , The same elements are therefore designated by the same reference numerals and will not be described. Instead of in FIG. 2 shown switch 17, with the help of individual gripper-carrying conveyor elements are selectively fed to one or the other storage and further processing, a carousel 20 or other displacement device is used here, with the whole filled with such conveying elements channel pieces 21 are rotated or moved differently and thereby optional can be connected to further channels. Also for this type of distribution of the conveyed are independent of each other eligible conveying elements necessary.

Figur 4 zeigt als Beispiel einer in das erfindungsgemässe Verfahren einbaubaren Weiterverarbeitungsstation ein Zwischenlager (Draufsicht), in dem die vom Greiferförderer geförderten Bogenstapel 8 nicht nur zwischengelagert und dabei gegebenenfalls getrocknet, sondern insbesondere auch umorganisiert werden können. Auch hier ist es notwendig, dass die Bogenstapel 8 von einzeln verfahrbaren Greifern 7' gehalten werden. Die von den Greifern 7' gehaltenen Bogen oder Bogenstapel werden in einem Strom 30, der am Ausgang der bogenverarbeitenden Maschine, das heisst bei der Übernahme der Bogen durch den Greiferförderer gebildet wird, dem Zwischenlager 31 zugeführt. Am Eingang des Zwischenlagers 31 werden die Bogenstapel zusammen mit den Greifern 7' einzeln oder in Zügen von aufeinanderfolgenden Greifern 7' mittels Weiche 32 nach Bedarf oder nach anderen Kriterien wahlweise auf verschiedene, funktionsmässig parallele Förderwege 11.1, 11.2, 11.3, 11.4 verteilt. Vom Ausgang dieser Förderwege werden die Bogenstapel mit den Greifern an einen weiteren Förderer 32 (schematisch als strichpunktierten Linie dargestellt) übergeben, wobei der weitere Förderer 32 beispielsweise äquidistante Mitnehmer 33 für die greifertragenden Förderelemente aufweist, mit denen solche Förderelemente wahlweise von einem der Förderwege 11.1 bis 11.4 mitgenommen werden können. Dabei wird die hängende Lage der Bogenstapel beispielsweise beibehalten, die Bogenstapel werden aber beispielsweise in Förderrichtung ausgerichtet und hintereinander angeordnet weggefördert. FIG. 4 shows an example of a built-in process according to the invention further processing station an intermediate storage (top view) in which the conveyed from the gripper conveyor sheet stack 8 not only stored and thereby possibly dried, but in particular can also be reorganized. Again, it is necessary that the sheet stack 8 are held by individually movable grippers 7 '. The sheet or stack of sheets held by the grippers 7 'are fed to the intermediate store 31 in a stream 30 which is formed at the outlet of the sheet-processing machine, that is to say when the sheets are taken over by the gripper conveyor. At the entrance of the intermediate storage 31, the sheet stacks are distributed together with the grippers 7 'individually or in trains of successive grippers 7' by means of switch 32 as needed or according to other criteria optionally on different, functionally parallel conveying paths 11.1, 11.2, 11.3, 11.4. From the exit of these conveyor routes the sheet stack with the grippers to another conveyor 32 (shown schematically as dotted line) passed, the further conveyor 32, for example, equidistant carrier 33 for the gripper-carrying conveyor elements, with which such conveyor elements can be taken from one of the conveyor paths 11.1 to 11.4 , In this case, the suspended position of the sheet stack is maintained, for example, but the sheet stack are, for example, aligned in the conveying direction and arranged away one behind the other.

Figur 5 zeigt eine weitere Übergabe von auf einer Bogenauflage 3 abgelegten Bogenstapeln 8 an die Greifer 7 des Greiferförderers 6. Diese Ausführungsform ist insbesondere geeignet für die Handhabung von Bogen, die wegen Beschädigungsgefahr parallel zu ihren Oberflächen weder relativ zu stationären Vorrichtungsteilen noch relativ zu benachbarten Bogen bewegt werden dürfen. Gleiche Elemente sind mit gleichen Bezugsziffern bezeichnet wie in Figur 1. FIG. 5 shows a further transfer of deposited on a sheet support 3 sheet stacks 8 to the gripper 7 of the gripper conveyor 6. This embodiment is particularly suitable for the handling of sheets that are moved due to risk of damage parallel to their surfaces neither relative to stationary device parts nor relative to adjacent sheets allowed to. Identical elements are designated by the same reference numerals as in FIG FIG. 1 ,

Es sind wiederum eine Mehrzahl von Bogenauflagen 3 vorgesehen, die für die Übergabe nicht nur abwärts bewegt sondern auch gedreht werden, derart, dass sie die primär durch die Greifer 7 des Greiferförderers 6 gesteuerte Umorientierung der der Bogenstapel 8 unterstützen können. Sobald die Bogenstapel 8 und die Bogenauflagen 3 eine senkrechte Lage haben, wird die Bogenauflage 3 relativ zu Bogenstapel beschleunigt und, sobald sie davon einen genügenden Abstand hat, beispielsweise gegen unten weggeführt.Again, a plurality of sheet supports 3 are provided which not only move downwardly for transfer but are also rotated so as to support the reorientation of the sheet stack 8 primarily controlled by the grippers 7 of the gripper conveyor 6. Once the sheet stack 8 and the sheet supports 3 have a vertical position, the sheet support 3 is accelerated relative to sheet stack and, as soon as it has a sufficient distance away, for example, led away down.

Vorteilhafterweise werden die Bogenstapel 8 von den Greifern 7 des Greiferförderers 6 erfasst, bevor die Bogenauflage 3 abgedreht wird, damit die Bogen auf der Bogenauflage 3 auf keinen Fall rutschen können. Sind die Bogenauflagen 3 aber mit hinteren Bogenanschlägen 40 ausgerüstet und sind die Bogen relativ stabil, ist es auch möglich, die Bogenstapel 8 erst zu erfassen, wenn die Bogenauflage 3 bereits in einer Schräglage ist.Advantageously, the sheet stacks 8 are detected by the grippers 7 of the gripper conveyor 6 before the sheet support 3 is turned off, so that the sheets on the sheet support 3 can slip in any case. Are the sheet supports 3 but equipped with rear sheet stops 40 and the sheets are relatively stable, it is also possible to detect the sheet stack 8 until the sheet support 3 is already in an inclined position.

Offensichtlich ist es auch für die in Figur 5 gezeigte Ausführungsform möglich, die Bogenauflagen 3 nicht nur in der gezeigten Weise zu bewegen sondern sie zusätzlich vor der Ergreifung der Bogenstapel durch die Greifer 7 seitlich, das heisst senkrecht zur Papierebene der Figur 5 zu verschieben, wie dies weiter oben für die Ausführungsform gemäss Figur 1 beschrieben ist.Obviously it is also for those in FIG. 5 embodiment shown possible to move the sheet supports 3 not only in the manner shown but also in addition to the seizure of the sheet stack by the gripper 7 side, that is perpendicular to the plane of the paper FIG. 5 to postpone, as described above for the embodiment according to FIG. 1 is described.
