A remaining-stack carrying device (3) in a sheet feeder (2) is used in non-stop stack changing. The remaining-stack carrying device (3) is integrated into the stack feeder (2) to simplify retrofitting. A remaining-stack lifting gear (5) uses the lifting elements present in each sheet feeder (2) for lifting and lowering during stack exchange.

Description

StapelwechselvorrichtunqStack changing device
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Es ist bekannt, in Bogenanlegern von Bogendruckmaschinen oder anderen bogenverarbeitenden Maschinen Einrichtungen für den automatisiertenIt is known to use devices for the automated in sheet feeders of sheet-fed printing machines or other sheet-processing machines
Stapelwechsel vorzusehen. Diese können aus rechenartigen Gebilden bestehen, sogenannten Reststapeltragvorrichtungen, die mit Schub- und Hubantrieben zur horizontalen und vertikalen Bewegung versehen sind. Solche sogenannte Nonstop-Stapelwechsler sind geeignet, beispielsweise während des Verdruckens von Papierbogen, d.h. im Maschinenlauf, Reste von abgearbeiteten Bogenstapeln von einer beispielsweise mit Nuten versehenen Palette zu übernehmen und auf einem nachfolgend in den Bogenanleger eingesetzten neuen Bogenstapel wieder abzusetzen. Bekannte Vorrichtungen zeichnen sich durch großen konstruktiven und montagetechnischen Aufwand aus und erfordern Spezialkonstruktionen der Bogenanleger. Des weiteren werden hierbei Vorrichtungen eingesetzt, deren Reststapeltragvorrichtung einen in die Nuten der Palette eingreifenden Rechen aufweisen. Dieser Rechen ist bei der Vereinigung des Reststapels mit dem neu eingesetzten Bogenstapel als Ganzes zwischen den beiden Stapelteilen zu entfernen. Das bringt hohe Antriebskräfte mit sich und beansprucht die der Schnittstelle nächstliegenden Bogen der Stapel sehr stark. Außerdem sindTo provide stack changes. These can consist of rake-like structures, so-called residual stack support devices, which are provided with linear and vertical drives for horizontal and vertical movement. Such so-called non-stop stack changers are suitable, for example during the printing of paper sheets, i.e. in the machine run to take over remnants of processed sheet stacks from a pallet provided with grooves, for example, and to deposit them again on a new sheet stack subsequently inserted into the sheet feeder. Known devices are characterized by great design and assembly costs and require special designs of sheet feeders. In addition, devices are used here whose residual stack support device has a rake which engages in the grooves of the pallet. This rake must be removed as a whole between the two parts of the stack when the remaining stack is combined with the newly inserted stack of sheets. This entails high driving forces and places a great strain on the sheets of the stack closest to the interface. Also are
Rückhaltemittel vorzusehen, die ein Verschieben der Stapelteile verhindern und dabei die Stapelkanten stark beanspruchen. Außerdem wird die Bedienung des Bogenanlegers selbst stark behindert oder gar unmöglich gemacht. Der Bogeniauf ist beim Wechselvorgang schwer zu beherrschen, so daß immer wieder Makulaturbogen entstehen. Es wurden schon Vorrichtungen entwickelt, die einige der geschilderten Nachteile teilweise vermeiden.To provide restraining means that prevent the stack parts from moving and thereby place great stress on the stack edges. In addition, the operation of the sheet feeder itself is severely hindered or even made impossible. The sheet is difficult to control when changing, so that waste sheets are always produced. Devices have already been developed which partially avoid some of the disadvantages described.
So ist aus der DE 3931710 C2 ein Non-Stop-Bogenanleger für Bogenrotationsmaschinen bekannt. Er weist eine Reststapeltragvorrichtung auf, die unterhalb eines vom Bogenanleger zur Bogenrotationsmaschine führenden Bändertisches angeordnet ist. Die Reststapeltragvorrichtung weist einen geschlossenen Rahmen auf, an dem Non-Stop-Stangen angeordnet sind, die als Kolbenstangen einzelner Zylinder mittels eines Druckmediums angetrieben werden können und die in Nuten einer einen Bogenstapel tragenden Palette einfahrbar sind. Die Non-Stop-Stangen liegen in eingefahrenem Zustand auf beiden Seiten des Rahmens auf und sollen nacheinander aus dem Bereich des Bogenanlegers entfernt werden. Über die Reihenfolge ist nichts ausgesagt. Die Überbrückung des durch die Non-Stop-Stangen bedingten Spalts zwischen Haupt- und Reststapel ist bei der Stapelvereinigung ein Hindernis für eine einwandfreie kontinuierlicheA non-stop sheet feeder for sheet-fed rotary machines is known from DE 3931710 C2. It has a residual stack carrying device which is arranged below a belt table leading from the sheet feeder to the sheet rotation machine.

Aus der DE 4203500 A1 ist ein Bogenanleger bekannt. Er weist parallel zum Bogenanleger und diesem stirnseitig zugeordnet eine Hilfstapeltragvorrichtung als eigenständige Baueinheit auf. Darin sind über einen gemeinsamen Antrieb einzeln antreibbare Spieße vorgesehen, die in Nuten einer einen Bogenstapel tragenden Palette einfahrbar sind. Der Antrieb weist einzelne Kettentriebe auf, die an die jeweiligen Spieße ankoppelbar sind. Für die Führung und Zugänglichkeit der Kettentriebe sind besondere konstruktive Maßnahmen erforderlich. DieA sheet feeder is known from DE 4203500 A1. In parallel to the sheet feeder and associated with it on the end face, it has an auxiliary stack support device as an independent structural unit. In it, individually drivable skewers are provided via a common drive, which are retractable into grooves in a pallet carrying a stack of sheets. The drive has individual chain drives that can be coupled to the respective skewers. Special constructive measures are necessary for the guidance and accessibility of the chain drives. The
Kettentriebe versperren den Raum vor dem Bogenanleger vollständig, sodaß dieser nicht zugänglich ist. Beim Stapelwechsel ist vorgesehen, die Spieße bei der Vereinigung von Haupt- und Reststapel zunächst an der Außenseite, dann in der Mitte und zuletzt im Bereich zwischen den bereits gezogenen Spießen aus dem Stapelbereich zu entfernen, sodaß sich eine sanfte Ablage des Reststapels auf dem Bogenstapel ergeben soll. Dies gelingt aber in der erforderlichen Genauigkeit nur bei schweren Materialien wie Bögen aus Metall, da die Bögen sich in verschiedenen Richtungen wölben und über einen großen Spalt absenken müssen, der durch die Spieße gebildet wird.Chain drives completely block the space in front of the sheet feeder so that it is not accessible. When changing stacks, it is intended to remove the skewers from the stacking area, first on the outside, then in the middle and finally in the area between the skewers that have already been drawn, so that the remaining stack is placed gently on the sheet stack should. However, this is only possible with the required accuracy for heavy materials such as metal arches, since the arches are in bulge in different directions and lower over a large gap formed by the skewers.
Weiterhin ist aus der DAS 1095297 ein Bogenanleger mit mehreren Stapelhubwerken bekannt. Er weist eine gabelförmige Reststapeltragvorrichtung auf, die mit in Nuten einer Palette einschiebbaren Reststapelstäben versehen ist. Die Vorrichtung ermöglicht die Übernahme eines Rests eines Bogenstapels von der Palette zur kontinuierlichen Zufuhr der Bogen während ein neuer Bogenstapel in den Bogenanleger eingesetzt wird. Die Reststapelvorrichtung ist mit einem separaten Hubwerk parallel zu dem Hauptstapelhubwerk innerhalb desFurthermore, a sheet feeder with several stacking hoists is known from DAS 1095297. It has a fork-shaped residual stack support device which is provided with residual stack rods that can be inserted into grooves in a pallet. The device enables a remnant of a stack of sheets to be transferred from the pallet for the continuous feeding of the sheets while a new stack of sheets is being inserted into the sheet feeder. The rest of the stacking device is parallel to the main stacking mechanism within the

The working area of the residual pile carrier is restricted. The rest of the stack support device hinders access to the sheet feeder.
Ziel der Erfindung ist es die Vorrichtung zum Stapelwechsel so zu verbessern, daß die geschilderten Nachteile vermieden werden.The aim of the invention is to improve the device for stack change so that the disadvantages described are avoided.
Aufgabe der Erfindung ist es, eine Vorrichtung der genannten Art so zu verbessern, daß die Vorrichtung auf einfache Weise in einen Bogenanleger integrierbar ist.The object of the invention is to improve a device of the type mentioned so that the device can be easily integrated into a sheet feeder.
Die Lösung der gestellten Aufgabe ergibt sich aus den Patentansprüchen.The solution to the problem arises from the patent claims.
Vorteilhaft ist, daß voneinander unabhängig bewegbare Trag- und Distanzstäbe in der Vorrichtung vorgesehen sind, die zur Entlastung des Bogenstoffes nicht gleichzeitig, sondern zeitversetzt aus dem Stapelbereich gezogen werden. Die Antriebskräfte werden dadurch gering gehalten und der Aufwand für die Antriebe der Reststapelstäbe ist reduziert. Die Vorrichtung kann daher anstatt einer manuellen Non-Stop-Einrichtung an einem Bogenanleger eingesetzt und auch nachgerüstet werden, ohne daß aufwendige Baumaßnahmen und großer Platzbedarf entsteht. Die Erfindung wird im folgenden anhand von Zeichnungen näher dargestellt. Hierbei zeigen:It is advantageous that independently movable support and spacer bars are provided in the device, which are drawn from the stacking area not at the same time, but with a time delay, to relieve the sheet material. The drive forces are kept low and the effort for driving the remaining stacking bars is reduced. The device can therefore be used instead of a manual non-stop device on a sheet feeder and can also be retrofitted without complex construction measures and large space requirements. The invention is illustrated below with reference to drawings. Here show:

In Figur 1 ist ein Bogenanleger 2 verbunden mit einer bogenverarbeitenden Maschine, beispielsweise mit einer Bogendruckmaschine 1 dargestellt. Im Bogenanleger 2 ist ein Bogenstapel S zur Verarbeitung eingesetzt. Der Bogenstapel S kann mittels eines Hauptstapelhubwerkes, das hier nicht näher dargestellt ist, im Takt der Bogenverarbeitung angehoben werden. Die Bogen des Bogenstapels S werden an dessen Oberseite vereinzelt und der Bogendruckmaschine 1 in einem Bogenstrom zugeführt. Im Bogenanleger 2 ist dazu eine Bogenvereinzelungseinrichtung 4 vorgesehen. Im Bogenanleger 2 ist weiterhin eine Reststapeltragvorrichtung 3 angeordnet, die der der Bogendruckmaschine 1 abgewandten Stirnseite' des Bogenanlegers 2 zugeordnet ist. Die Reststapeltragvorrichtung 3 ist mit einem Gestell 6 versehen, in dem Reststapelstäbe 7 längsverschiebbar gelagert sind. Mittels des Gestelles 6 ist die Reststapeltragvorrichtung 3 an einem Reststapelhubwerk 5 aufgehängt. Das Reststapelhubwerk 5 ist hier nur in seiner Lage, nicht jedoch in Einzelheiten angedeutet. Das Reststapelhubwerk 5 dient dazu einen Reststapel H im Bogenanleger 2 zu halten und im Takt der Bogenverarbeitung anzuheben. Daher ist das Reststapelhubwerk 5 auch mit dem Hauptstapelhubwerk synchron steuerbar. Das Reststapelhubwerk 5 besteht aus mit dem Bogenanleger 2 verbundenen vertikalen Führungsschienen 8, an denen das Gestell 6 geführt ist, und weist beispielsweise Hubketten auf, mittels derer die Reststapeltragvorrichtung 3 anhebbar oder absenkbar ist.FIG. 1 shows a sheet feeder 2 connected to a sheet processing machine, for example a sheet printing machine 1. A sheet stack S is used in the sheet feeder 2 for processing. The sheet stack S can be lifted in time with the sheet processing by means of a main stack lifting device, which is not shown here. The sheets of the sheet stack S are separated at the top and fed to the sheet printing machine 1 in a sheet stream. For this purpose, a sheet separation device 4 is provided in the sheet feeder 2. In the sheet feeder 2 there is also a residual stack support device 3 which is assigned to the end face 'of the sheet feeder 2 facing away from the sheet printing machine 1. The rest of the stack support device 3 is provided with a frame 6 in which the rest of the stacking rods 7 are longitudinally displaceable. The residual stack support device 3 is suspended from a residual stack lifting mechanism 5 by means of the frame 6. The rest of the stacking hoist 5 is only in its position here, but not indicated in detail. The residual pile hoist 5 serves to hold a residual pile H in the sheet feeder 2 and to raise it in time with the sheet processing. Therefore, the remaining stacking hoist 5 can also be controlled synchronously with the main stacking hoist. The residual pile hoist 5 consists of vertical guide rails 8 connected to the sheet feeder 2, on which the frame 6 is guided, and has lifting chains, for example, by means of which the residual pile support device 3 can be raised or lowered.
In Figur 2 ist der Bogenanleger 2 in einer Ansicht von oben gezeigt. An den Bogenanleger 2 schließt sich in der durch Pfeile angedeuteten Bogenlaufrichtung ein sogenannter Bändertisch 20 an, über den der durch die Vereinzelung erzeugte Bogenstrom zu der bogenverarbeitenden Maschine z.B. der Druckmaschine 1 transportiert wird. Die Orientierung der Reststapelstäbe 7 ist in ihrer Anordnung in Bezug auf den Bogenanleger 2 dargestellt, wobei nur die beiden äußeren Reststapelstäbe 7 dargestellt sind und die anderen mit Wirkungslinien angedeutet werden. Die gezeigte Position ist beispielsweise die Bereitschaftsstellung vor der Einleitung eines Wechselvorganges bzw. die Warteposition außerhalb des Bedienungsbereiches des Bogenanlegers 2. Die Reststapelstäbe 7 sind dabei innerhalb der Reststapeltragvorrichtung 3 geführt, sodaß sie in der gezeigten Position eine horizontale Stellung außerhalb des Bereiches des Bogenanlegers 2 einnehmen. Die Reststapelstäbe 7 sind in dickere Tragstäbe und dünnere Distanzstäbe unterteilt und abwechselnd angeordnet. Die Reststapeltragvorrichtung 3 mit ihrem Gestell 6 ist mittels der Führungsschienen 8 am Bogenanleger 2 geführt und vertikal bewegbar. Das Reststapelhubwerk 5 ist in seiner Lage angedeutet und befindet sich wie allgemein üblich an der Oberseite der Führungsschienen 8, beispielsweise am Rahmen des Bogenanlegers 2, greift von dort aus am Gestell 6 der Reststapeltragvorrichtung 3 an und bewegt diese an den Führungschienen 8 aufwärts und abwärts.In Figure 2, the sheet feeder 2 is shown in a view from above. A sheet table 20 adjoins the sheet feeder 2 in the sheet travel direction indicated by arrows, via which the table 20 produced by the separation Sheet current is transported to the sheet processing machine, for example the printing press 1. The orientation of the remaining stacking bars 7 is shown in their arrangement in relation to the sheet feeder 2, only the two outer remaining stacking bars 7 being shown and the others being indicated with lines of action. The position shown is, for example, the standby position before the initiation of a change process or the waiting position outside the operating area of the sheet feeder 2. The remaining stacking bars 7 are guided within the remaining stacking support device 3, so that in the position shown they assume a horizontal position outside the area of the sheet feeder 2 . The remaining stacking bars 7 are divided into thicker carrying bars and thinner spacing bars and arranged alternately. The rest of the stack support device 3 with its frame 6 is guided on the sheet feeder 2 by means of the guide rails 8 and can be moved vertically. The rest of the stacking hoist 5 is indicated in its position and, as is generally the case, is located on the top of the guide rails 8, for example on the frame of the sheet feeder 2, from there engages the frame 6 of the rest of the stacking support device 3 and moves it up and down on the guide rails 8.
Figur 1 zeigt, daß die Reststapeltragvorrichtung 3 mittels der Führungsschienen 8 direkt im Bogenanleger 2 eingebaut ist. Das Reststapelhubwerk 5 ist einerseits während der Versorgung der Druckmaschine 1 mit Bogen heb- /senkbar und die Reststapeltragvorrichtung 3 ist außerhalb des Verarbeitungsbereiches für den eigentlichen Stapelwechsel bewegbar.Figure 1 shows that the residual stack support device 3 is installed directly in the sheet feeder 2 by means of the guide rails 8. The residual stack lifting mechanism 5 can be raised / lowered on the one hand during the supply of the printing press 1 with sheets, and the residual stack support device 3 can be moved outside the processing area for the actual stack change.
Der Stapelwechsel läuft also wie folgt ab:The batch change therefore takes place as follows:

Zur Ermöglichung dieses Ablaufes ist in den Figuren 3 bis 5 schematisch dargestellt wie das Reststapelhubwerk 5 wirkt. Das Reststapelhubwerk 5 weist drei Paare von Hubketten 60, 61 und 62 auf. Die Hübketten 60 (strichliert) sind auf der vorderen der bogenverarbeitenden Maschine zugeordneten Seite des Reststapelhubwerkes 5 angeordnet. Auf dieser Seite ist auch die Reststapelhubschiene mit den Hubketten 60 gekoppelt. Sie liegt beispielsweise in einer Vertikalführung auf hier nicht gezeigten Auflageanschlägen auf und kann von dort mittels des Reststapelhubwerkes 5 abgehoben werden. Die Hubketten 61 (strich-doppelt-punktiert) sind der dem gegenüberliegenden hinteren Seite des Reststapelhubwerkes 5 zugeordnet. Die Hubketten 62 (strich-punktiert) sind dem Gestell 6 der Reststapeltragvorrichtung 3 zugeordnet. Die Hubketten 60 und 61 sind über Kettenumlenkräder im Gestell des Bogenanlegers 1 zu einem Reststapelhubantrieb 63 geführt. Die Hubketten 60 bis 62 werden beiderseits des Bogenanlegers 2 über hier nur angedeutete Umlenkkettenräder in Traversen 64 geführt. Die Traversen 64 sind im Gestell des Bogenanlegers 2 mit der Reststapeltragvorrichtung 3 verbunden und gemeinsam mit dieser mittels des Reststapelhubwerkes 5 an den Führungschienen 8 vertikal verschiebbar geführt. Die Traversen 64 weisen an ihren vorderen Enden Auflagen auf, auf denen die Reststapelhubschiene mitgeführt werden kann. Dazu wird die Reststapelhubschiene bei der Hubbewegung des Reststapelhubwerkes 5 und damit der Traversen 64 von ihrer unteren Endlage oder Wartestellung aus auf den Auflageanschlägen abgehoben und mit der Reststapeltragvorrichung 3 angehoben. Die Reststapelhubschiene kann selbstverständlich auch fest mit den Traversen 64 verbunden sein.To make this process possible, FIGS. 3 to 5 show schematically how the residual stack lifting mechanism 5 acts. The residual stacking hoist 5 has three pairs of lifting chains 60, 61 and 62. The pretty chains 60 (dashed lines) are arranged on the front side of the residual stack lifting mechanism 5 assigned to the sheet-processing machine. The residual stack lifting rail is also coupled to the lifting chains 60 on this side. It rests, for example, in a vertical guide on support stops, not shown here, and can be lifted off from there by means of the residual stacking hoist 5. The lifting chains 61 (dash-double-dotted) are assigned to the opposite rear side of the residual stack lifting mechanism 5. The lifting chains 62 (dash-dotted) are assigned to the frame 6 of the residual stack support device 3. The lifting chains 60 and 61 are connected to one another via chain deflection wheels in the frame of the sheet feeder 1 Remaining stack lift drive 63 performed. The lifting chains 60 to 62 are guided in traverses 64 on both sides of the sheet feeder 2 via deflection chain wheels which are only indicated here. The crossbeams 64 are connected in the frame of the sheet feeder 2 to the rest of the stack support device 3 and, together with the latter, are guided vertically displaceably on the guide rails 8 by means of the rest of the stacking hoist 5. The traverses 64 have supports at their front ends, on which the remaining stacking lifting rail can be carried. For this purpose, the residual stack lifting rail is lifted from the lower end position or waiting position on the support stops during the lifting movement of the residual stack lifting mechanism 5 and thus the crossbeams 64 and raised with the residual stack support device 3. The residual stack lifting rail can of course also be firmly connected to the cross members 64.
Die Enden der Hubketten 60 und 61 sind auf der Traverse 64 mit einem verschiebbaren Lagerbock 65 fest verbunden. Auf dem verschiebbaren Lagerbock 65 ist ein Umlenkkettenrad 66 gelagert. Um das Umlenkkettenrad 66 wird die Hubkette 62 in einer Schlaufe herumgeführt. Die Hubkette 62 wird weiterhin über ein Umlenkkettenrad 67 von der Traverse 64 nach oben zu einem Umlenkkettenrad 68 an einer mit der Reststapeltragvorrichtung 3 mitgewegten Halterung 69 oder am oberen Ende der Führungsschiene 8 geführt und läuft von dort wieder nach unten. Die Enden der Hubkette 62 sind einerseits an der Traverse 64 und andererseits am Gestell 6 der Reststapeltragvorrichtung 3 fest angeschlagen. Infolge des Gewichts der Reststapeltragvorrichtung 3 zusammen mit den Traversen 64 wird die Hubkette 62 über die Schlaufe um das Umlenkkettenrad 66 gegen die Hubketten 60 und 61 und damit auch gegen den Reststapelhubantrieb 63 verspannt.The ends of the lifting chains 60 and 61 are fixedly connected to the cross member 64 with a displaceable bearing block 65. A deflection sprocket 66 is mounted on the displaceable bearing block 65. The lifting chain 62 is guided in a loop around the deflection sprocket 66. The lifting chain 62 is further guided via a deflecting sprocket 67 from the cross member 64 upwards to a deflecting sprocket 68 on a holder 69 carried along with the rest of the stack support device 3 or at the upper end of the guide rail 8 and runs downwards again from there. The ends of the lifting chain 62 are attached on the one hand to the crossmember 64 and on the other hand to the frame 6 of the residual stack support device 3. As a result of the weight of the residual stack support device 3 together with the crossbeams 64, the lifting chain 62 is tensioned via the loop around the deflection chain wheel 66 against the lifting chains 60 and 61 and thus also against the residual stack lifting drive 63.
In der tiefen Position nach Fig. 3 sind die Hubketten 60 und 61 weitgehend ausgefahren. Der verschiebbare Lagerbock 65 mit dem Umlenkkettenrad 66 ist in dieser Betriebslage durch die Kettenschlaufe nach rechts gegen einen Anschlag fixiert. Das Gestell 6 der Reststapeltragvorrichtung 3 hängt in den Hubketten 62. Es kann gegenüber den Traversen auch nach unten hin auf einem Anschlag aufsitzen. Die Hubkette 62 wird dann über die Kettenschlaufe am Lagerbock 65 gespannt.3, the lifting chains 60 and 61 are largely extended. In this operating position, the displaceable bearing block 65 with the deflection sprocket 66 is fixed against a stop by the chain loop to the right. The frame 6 of the remainder of the stack support device 3 hangs in the lifting chains 62. It can also face downwards against a crossbar on a stop sit on. The lifting chain 62 is then stretched over the chain loop on the bearing block 65.
Beim Anheben der Reststapeltragvorrichtung 3 werden wie in Figur 4 gezeigt die Hubketten 60 und 61 vom Reststapelhubantrieb 63 eingezogen. Der Lagerbock 65 wird weiterhin über die Kettenschlaufe in seiner durch die Länge der Hubkette 62 begrenzten rechten Endlage gehalten. An der höchst möglichen Betriebsstellung der Reststapeltragvorrichtung 3 im Stapelbereich laufen die Traversen 64 gegen Anschläge an, die hier nicht gezeigt sind. Nun ist eine weiter Hubbewegung der Traversen 64 zusammen mit dem Gestell 6 nicht möglich.When the residual stack support device 3 is raised, the lifting chains 60 and 61 are drawn in by the residual stack lifting drive 63, as shown in FIG. The bearing block 65 is still held in the right end position limited by the length of the lifting chain 62 via the chain loop. At the highest possible operating position of the residual stack support device 3 in the stack area, the cross members 64 run against stops, which are not shown here. Now a further lifting movement of the cross members 64 together with the frame 6 is not possible.
In Figur 5 wird schließlich die Außerbetriebstellung der Reststapeltragvorrichtung 3 gezeigt. Durch weiteres Betätigen des Reststapelhubantriebes 63 wird über die Hubbewegung der Hubketten 60 und 61 der Lagerbock 65 auf den Traversen 64 nach links verschoben. Dabei läuft die Hubkette 62 über die Umlenkkettenrolle 66, 67 und 68 ab. Die Schlaufe in der Hubkette 62 wird dabei verlängert, während das am Gestell 6 befestigte Ende der Hubkette 62 eingezogen wird. Damit wird das Gestell 6 von den Traversen 64 abgehoben und über die obere Endlage der Traversen 64 hinaus angehoben. Das die Reststapelstäbe 7 tragende Gestell 6 der Reststapeltragvorrichtung 3 wird so in eine Parkposition gebracht. In dieser Position ist es außer Betrieb genommen.Finally, FIG. 5 shows the non-operating position of the residual stack support device 3. By further actuation of the residual stacking stroke drive 63, the bearing block 65 on the crossbeams 64 is displaced to the left via the lifting movement of the lifting chains 60 and 61. The lifting chain 62 runs over the deflection chain roller 66, 67 and 68. The loop in the lifting chain 62 is extended while the end of the lifting chain 62 fastened to the frame 6 is drawn in. The frame 6 is thus lifted from the cross members 64 and raised beyond the upper end position of the cross members 64. The frame 6 of the remaining stack supporting device 3 carrying the remaining stacking rods 7 is thus brought into a parking position. In this position it is out of service.
Beim Absenken des Gestells 6 und erreichen der Traversen 64 verbinden sich die beiden Teile der Reststapeltragvorrichtung 3 wieder und sinken unter der Gewichtsbelastung mit verspannter Hubkette 62 gemeinsam ab.When the frame 6 is lowered and the traverses 64 reach, the two parts of the rest of the stack support device 3 reconnect and sink together under the weight load with the tensioned lifting chain 62.
Das Reststapelhubwerk 5 ist in Einzelheiten auch anders gestaltbar. So kann die Hubwirkung der Hubkette 62 durch veränderte Umlenkungen im Bereich der Schlaufe vergrößert oder verkleinert werden. Hier kommt beispielsweise die Wirkung eines Flaschenzuges in Frage. Weiterhin kann die Verbindung sowohl des Lagerbockes 65 als auch die Verbindung des Gestelles 6 mit den Traversen 64 verriegelbar gestaltet werden. Dies ist aber nach den bisherigen Erfahrungen nicht erforderlich. Die in den Bogenanleger integriert gestaltete Reststapeltragvorrichtung 3 mit selbststeuerndem Aufzug des die Reststapelstäbe 7 tragenden Gestelles 6 ermöglicht die Nachrüstung vorhandener Bogenanleger 2 mit der genannten Ausrüstung zum automatischen Stapelwechsel. Hierbei ist trotz erweiterter Funktionsmöglichkeiten kein zusätzlicher Bauraum erforderlich, wie dies bei anderen bekannten Vorrichtungen der Fall ist. The rest of the stacking hoist 5 can also be designed differently in details. The lifting action of the lifting chain 62 can be increased or reduced by changing the deflections in the area of the loop. Here, for example, the effect of a pulley comes into question. Furthermore, the connection of both the bearing block 65 and the connection of the frame 6 to the cross members 64 can be made lockable. However, based on previous experience, this is not necessary. The residual stack support device 3, which is integrated into the sheet feeder and has a self-controlling elevator of the frame 6 carrying the remaining stacking rods 7, enables existing sheet feeders 2 to be retrofitted with the aforementioned equipment for automatic stack change. Despite the expanded functionality, no additional installation space is required, as is the case with other known devices.
