Description

Die Erfindung betrifft eine Vorrichtung zur Ausrichtung von in einer Lage übereinander angeordneten Bogen gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a device for aligning sheets arranged one above the other in accordance with the preamble of claim 1.

Vorrichtungen werden beispielsweise, jedoch keineswegs ausschliesslich, dazu eingesetzt, bedruckte Bogen an zumindest einer Kante mit ausreichender Genauigkeit übereinander liegend auszurichten, so dass der Stapel anschliessend an den Kanten beschnitten werden kann. Bei manchen Druckerzeugnissen, beispielsweise mit Registriernummern versehenen Wertnoten, ist es nach dem Bedrucken der Bogen erforderlich, dass die Reihenfolge der Bogen in der einen Stapel bildenden Lage erhalten bleibt.Devices are for example, but by no means exclusively, used to align printed sheets on at least one edge with sufficient accuracy lying over each other, so that the stack can then be trimmed at the edges. Some printed products, for example, with registration numbers provided with grades, it is after printing the sheets required that the order of the sheets in the stack-forming layer is maintained.

Die DE 68 09 156 U beschreibt eine Anordnung zum Herstellen eines geordneten Stapels von flachen Sendungen. Dabei werden unregelmässig ankommende Sendungen geschuppt und auf einem Stapel abgelegt.DE 68 09 156 U describes an arrangement for producing an ordered stack of flat items. In this case, irregular incoming shipments are scaled and stored on a pile.

Die DE-PS 12 32 986 offenbart eine Stapelvorrichtung für gefalzte Bogenlagen. Dabei werden die geschuppten Bogenlagen mittels eines Bändertransportsystems um einen Zylinder geführt und gewendet. Anschliessend werden die Bogenlagen an Anschlägen ausgerichtet und gestapelt.DE-PS 12 32 986 discloses a stacking device for folded sheet layers. The scaly sheet layers are guided by a belt transport system around a cylinder and turned. Subsequently, the sheet layers are aligned with stops and stacked.

Die EP 0 173 959 A1 zeigt eine Bogenverarbeitungsmaschine, der von einer Unterseite eines ersten Stapels Bogen zugeführt werden. Nach der Bearbeitung werden mittels eines Bändersystems die ungeschuppten Bogen zu einer Ablage transportiert und mit einem Saugförderer oben auf einem zweiten Stapel abgelegt.EP 0 173 959 A1 shows a sheet processing machine which is fed from a lower side of a first stack of sheets. After processing, the unequipped sheets are transported by means of a belt system to a tray and deposited with a suction conveyor on top of a second stack.

Aus der EP 06 14 840 A1 ist eine Vorrichtung bekannt, die in der Art eines Rütteltisches ausgebildet ist. Bei diesem Rütteltisch ist ein Auflagetisch vorgesehen, wobei an mindestens zwei, benachbarten Seiten des Auflagetisches seitliche Anschläge angeordnet sind, die an den Seitenkanten der Bogen zur Anlage kommen können. Zur Ausrichtung der Lage übereinander angeordneter Bogen wird die Lage auf den Auflagetisch aufgelegt und dieser anschliessend so weit in Richtung der beiden Anschläge geneigt, dass die Seitenkanten der Bogen aufgrund der Schwerkraft an den Anschlägen zur Anlage kommen. Danach wird der Rütteltisch in Vibration versetzt, um dadurch die Lage der Bogen aufzulockern und eine Ausrichtbewegung der einzelnen Bogen relativ zueinander zu ermöglichen.From EP 06 14 840 A1 a device is known which in the manner of a Vibrating table is formed. In this vibrating table, a support table is provided, wherein lateral stops are arranged on at least two adjacent sides of the support table, which can come to rest on the side edges of the sheet. For aligning the layer of sheets arranged one above the other, the layer is placed on the support table and this then so far inclined in the direction of the two stops that the side edges of the sheet come to rest on the attacks due to gravity. Thereafter, the vibrating table is vibrated to thereby loosen the position of the sheets and to allow an alignment movement of the individual sheets relative to each other.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Ausrichtung von in einer Lage übereinander angeordneten Bogen zu schaffen.The invention has for its object to provide a device and a method for aligning in a layer stacked sheet.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.This object is achieved according to the invention by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die Lage der Bogen mit nicht ausgerichteter Vorderkante nicht unmittelbar auf dem Auflagetisch abgelegt wird, sondern auf einer vorgelagerten Tragplatte. Dabei ist in der Vorrichtung ein Bogenanleger vorgesehen, der die auf der Tragplatte abgelegten Bogen einzeln abnimmt und unter Bildung eines untergeschuppten Schuppenstroms weiterfördert. In diesem untergeschuppten Schuppenstrom liegt die Vorderkante eines jeden Bogens jeweils unterhalb des unmittelbar vorhergehenden Bogens. Im Ergebnis wird also beim Vereinzeln die Reihenfolge der Bogen nicht verändert. Hinter dem Bogenanleger ist in der Vorrichtung eine Wendeeinrichtung vorgesehen, mit der der Schuppenstrom gewendet wird. Durch die Wendung des Schuppenstroms wird im Ergebnis erreicht, dass jeder Bogen im Bereich seiner Vorderkante frei zugänglich ist. Zur eigentlichen Ausrichtung der einzelnen Bogen ist dann hinter der Wendeeinrichtung eine Fördereinrichtung vorgesehen, mit der die Bogen einzeln zum Vorderkantenanschlag des Auflagetisches gefördert werden. Durch die Anlage der Vorderkante der Bogen am Vorderkantenanschlag wird die gewünschte Ausrichtung der Bogen erreicht und zugleich eine neue Lage von Bogen, die alle jeweils am Vorderkantenanschlag anliegen, gebildet.The advantages achieved by the invention are in particular that the position of the sheet with not aligned front edge is not stored directly on the support table, but on an upstream support plate. In this case, a sheet feeder is provided in the device, which individually decreases the deposited sheets on the support plate and further promotes to form a subdivided scale flow. In this shingled scale flow, the leading edge of each arc is below the immediately preceding arc. As a result, the order of the sheets is not changed when singulating. Behind the sheet feeder, a turning device is provided in the device, with which the shingled stream is turned. As a result of the turn of the scale flow, each arc is freely accessible in the area of its leading edge. For the actual orientation of the single sheet is then provided behind the turning device a conveyor, with which the sheets are conveyed individually to the leading edge stop of the support table. By the plant of the leading edge of the sheet on the leading edge stop the desired orientation of the sheet is achieved and at the same time a new layer of bow, all of which rest respectively on the leading edge stop formed.

Da die Bogen bei der Ausrichtbewegung am Vorderkantenanschlag jeweils oben auf der neu gebildeten Lage aufliegen, wird die Ausrichtbewegung nicht durch das Gewicht der anderen Bogen behindert. Zugleich wird jedoch die Reihenfolge der Bogen in der Lage, anders als beispielsweise beim Umstapeln, erhalten. Nach dem vollständigen Durchlauf aller Bogen der ursprünglichen Lage hat sich dann auf dem Auflagetisch eine neue Lage von Bogen mit ausgerichteter Vorderkante gebildet, wobei der ursprünglich oberste Bogen in der neuen Lage ganz unten liegt.Since the sheets rest on top of the newly formed ply in the alignment movement at the leading edge stop, the alignment movement is not hindered by the weight of the other sheets. At the same time, however, the order of the sheets is able to be obtained, unlike, for example, when stacking. After the complete passage of all the sheets of the original position then a new layer of sheet with aligned leading edge has formed on the support table, the original top sheet is in the new position at the bottom.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen :

  • Fig. 2 die Vorrichtung gemäss Fig. 1 in einem vergrösserten Ausschnitt in perspektivischer Ansicht von oben ;
  • Fig. 3 eine Wendeeinrichtung zur Verwendung in einer Vorrichtung gemäss Fig. 1 in perspektivischer Ansicht von unten.
An embodiment of the invention is illustrated in the drawings and will be described in more detail below. Show it :
  • 1 shows a device for aligning sheets in a perspective view from above.
  • FIG. 2 shows the device according to FIG. 1 in an enlarged detail in a perspective view from above; FIG.
  • Fig. 3 shows a turning device for use in a device according to FIG. 1 in a perspective view from below.

Zur Bildung einer Vorrichtung 01 kann ein bekannter Bogenanleger 02 verwendet werden. Im Bogenanleger 02 ist eine in Fig. 1 verdeckt dargestellte Tragplatte vorgesehen, auf die eine Lage von übereinander angeordneten Bogen 04, beispielsweise mit Wertnoten und Registriernummern bedruckte Bogen, abgelegt werden können. Durch Einsatz einer verfahrbaren Saugeinheit 03 werden die Bogen 04 in bekannter Art und Weise einzeln von der Lage abgenommen und unter Bildung eines untergeschuppten Schuppenstroms, bei dem die Bogen 04 mit ihrer Vorderkante jeweils unterhalb des vorhergehenden Bogens 04 liegen, in Richtung einer Wendeeinrichtung 06 weitergefördert.To form a device 01, a known sheet feeder 02 can be used. In the sheet feeder 02, a support plate shown hidden in Fig. 1 is provided, to which a layer of superimposed sheets 04, For example, with notes and registration numbers printed sheets can be stored. By using a movable suction unit 03, the sheet 04 are removed in a known manner individually from the situation and further promoted to form a shingled scale flow in which the sheet 04 with its leading edge below the previous sheet 04 in the direction of a turning device 06.

Zwischen Bogenanleger 02 und Wendeeinrichtung 06 ist eine Seitenziehmarke 07 vorgesehen, an der die rechte Seitenkante der einzelnen Bogen 04 des Schuppenstroms seitlich ausgerichtet werden.Between sheet feeder 02 and turning device 06, a side pull mark 07 is provided at which the right side edge of the individual sheets 04 of the scale flow are aligned laterally.

Die Fördergeschwindigkeit der Saugbänder 08 im Bogenanleger 02 ist dabei höher als die Fördergeschwindigkeit der Saugbänder 09 in der Wendeeinrichtung 06, so dass im Ergebnis die Fördergeschwindigkeit des Schuppenstroms nach Ausrichten der Bogen 04 an der Seitenziehmarke 07 verringert wird. Dadurch wird die Überlappung zwischen den einzelnen Bogen 04 im Schuppenstrom vergrössert und der Schuppenstrom somit langsamer weitergefördert, so dass der Materiallauf mit den bereits seitlich ausgerichteten Bogen 04 ruhiger wird. An einem Bedienpult 11 können Steuerbefehle für die Vorrichtung 01 eingegeben und verschiedene Betriebszustände angezeigt werden.The conveying speed of the suction belts 08 in the sheet feeder 02 is higher than the conveying speed of the suction belts 09 in the turning device 06, so that, as a result, the conveying speed of the scale flow is reduced after aligning the sheets 04 on the side pulling mark 07. As a result, the overlap between the individual sheets 04 in the scale flow is increased and the imbricated flow is thus conveyed more slowly, so that the material run with the already laterally oriented sheets 04 becomes calmer. On a control panel 11 control commands for the device 01 can be entered and various operating conditions are displayed.

Am Einlauf der Wendeeinrichtung 06 werden, wie in Fig. 2 dargestellt, die Bogen 04 zwischen den Saugbändern 09 und umlaufende Führungsbändern 12 eingezogen und um 150 -210 gewendet und in Richtung einer Walze 13, z. B. einer Saugwalze 13 weitergefördert. Die Saugwalze 13 läuft in Richtung des Bewegungspfeils 14 rotatorisch um, so dass die Bogen 04 des am Einlauf untergeschuppten Schuppenstroms derart gewendet werden, dass die Bogen 04 am Auslauf der Wendeeinrichtung 06 im Bereich ihrer Vorderkante jeweils frei zugänglich sind, wohingegen die Hinterkante jedes Bogens 04 unterhalb des jeweils nachfolgenden Bogens 04 im Schuppenstrom liegt.At the inlet of the turning device 06, as shown in Fig. 2, the sheet 04 between the suction belts 09 and circulating guide belts 12 retracted and turned by 150 -210 and in the direction of a roller 13, z. B. a suction roller 13 further. The suction roll 13 rotates in the direction of the movement arrow 14 so that the sheets 04 of the shingled underflow Schuppenstrom be turned so that the sheet 04 are freely accessible at the outlet of the turning device 06 in the region of its leading edge, whereas the trailing edge of each sheet 04 below the each subsequent arc 04 is in the imbricated stream.

Hinter dem Auslauf der Wendeeinrichtung 06 ist ein Auflagetisch 16 angeordnet, an dessen hinteren Ende ein in Fig. 2 verdeckt dargestellter Vorderkantenanschlag vorgesehen ist. Mittels einer als Fördereinrichtung 17 dienenden Saugkörpereinheit 17 mit zwei rotatorisch antreibbaren Saugkörper 18, z. B. eine Saugwalzen 18 können die einzelnen Bogen 04 des Schuppenstroms nacheinander im Bereich ihrer Vorderkante angesaugt und gegen den verdeckt dargestellten Vorderkantenanschlag gefördert werden. Durch fortlaufenden Betrieb der Vorrichtung 01 bildet sich auf dem Auflagetisch 16 eine neue Lage von übereinander angeordneten Bogen 04, deren Vorderkante und Seitenkante jeweils ausgerichtet ist. Damit die von der Saugkörpereinheit 17 auf die Bogen 04 der neuen Lage ausgeübte Gewichtskraft die Ausrichtung der Vorderkante nicht behindert, kann die Höhe der neuen Lage mit einem nicht dargestellten Sensor gemessen und die Saugkörpereinheit 17 in Abhängigkeit dieses Messwertes vertikal verstellt werden. Im Ergebnis befinden sich die Saugwalzen 18 mit ihrem Umfang damit immer in Höhe der Oberseite der neuen Lage und drücken damit nicht auf den jeweils auszurichtenden obersten Bogen 04.Behind the outlet of the turning device 06, a support table 16 is arranged at the rear end of a hidden in Fig. 2 illustrated front edge stop is provided. By means of a serving as a conveyor 17 Saugkörpereinheit 17 with two rotatably driven absorbent body 18, z. B. a suction rollers 18, the individual sheets 04 of the scale flow can be successively sucked in the region of its leading edge and conveyed against the front edge stopper shown hidden. By continuous operation of the device 01 forms on the support table 16, a new layer of stacked sheet 04, the leading edge and side edge is aligned. So that the weight force exerted by the suction-body unit 17 on the sheets 04 of the new layer does not hinder the alignment of the front edge, the height of the new layer can be measured with a sensor, not shown, and the absorbent-body unit 17 can be adjusted vertically as a function of this measured value. As a result, the suction rollers 18 with their circumference are thus always at the level of the top of the new layer and thus do not press on the respective top sheet 04 to be aligned.

Die Vorrichtung 01 kann beispielsweise wie folgt betrieben werden : Nachdem beispielsweise hundert Bogen 04 vom der Vorrichtung 01 abgezogen worden sind, wird die Vorrichtung 01 für eine bestimmte Zeit abgeschaltet, so dass der Bogenlauf unterbrochen wird. Die jeweils in einem Schuppenstrom zusammengefassten Bogen 04 werden dann durch die Wendeeinrichtung 06 zum Auflagetisch 16 hingefördert und dort unter Bildung einer neuen Lage abgestapelt. Sobald alle Bogen 04 des Schuppenstroms an der Vorderkantenmarke ausgerichtet sind, wird die jeweilige Lage vom Auflagetisch 16 in Richtung einer nachgeordneten Vorrichtung (nicht dargestellt), die beispielsweise dem Beschneiden der Kanten der Bogen 04 dient, weitergefördert.The device 01 can be operated, for example, as follows: After, for example, one hundred sheets 04 have been removed from the device 01, the device 01 is switched off for a certain time, so that the sheet travel is interrupted. Each summarized in a scale flow sheet 04 are then conveyed by the turning device 06 to the support table 16 and stacked there to form a new location. As soon as all the sheets 04 of the scale flow are aligned with the leading edge mark, the respective position is conveyed further from the support table 16 in the direction of a downstream device (not shown), which for example serves for trimming the edges of the sheets 04.

Während des gesamten Ablaufes zeigt das vorlaufende Ende des vom ersten Stapel abgenommenen Bogens in Transportrichtung, d. h. das vorlaufende Ende der Bogen ist, bezogen auf die Transportrichtung, auch beim Ablagestapel vorlaufend.Throughout the process, the leading end of the sheet removed from the first stack shows in the transport direction, i. H. the leading end of the sheet is, based on the transport direction, also leading the discard pile.

Beim Banknotendruck kann in der Vorrichtung 01 ein Kamerasystem 21 vorgesehen sein, mit der die Registriernummern der einzelnen Bogen 04 beobachtet werden können.In the case of banknote printing, a camera system 21 can be provided in the device 01 with which the registration numbers of the individual sheets 04 can be observed.

In Fig. 3 ist die Wendeeinrichtung 06 mit den umlaufenden Führungsbändern 12 und der Saugwalze 13 in perspektivischer Ansicht von unten dargestellt. Man erkennt, dass die Führungsbänder 12 am Auslauf der Wendeeinrichtung 06 entlang von Saugkästen 22 geführt sind und somit am Auslauf der Wendeeinrichtung 06 in der Art von Saugbändern 12 funktionieren. Dadurch wird gewährleistet, dass die Bogen 04 am Auslauf der Wendeeinrichtung 06 angesaugt und auf diese Weise ihre Lage gesichert wird.In Fig. 3, the turning device 06 is shown with the rotating guide belts 12 and the suction roller 13 in a perspective view from below. It can be seen that the guide belts 12 are guided along the outlet of the turning device 06 along suction boxes 22 and thus function at the outlet of the turning device 06 in the manner of suction belts 12. This ensures that the sheet 04 sucked at the outlet of the turning device 06 and in this way their position is secured.
