In Fig. 1 ist ein erfindungsgemäßer Bogenanleger 1 dargestellt. Er weist ein
Hauptstapelhubwerk 2, einen Saugkopf 3 zum Vereinzeln der Bogen von der Stapeloberseite
und einen Bogenführungstisch 4 zu einer bogenverarbeitenden Maschine
auf. Der Bogenanleger 1 weist feste Gestellseitenwände 10 auf. Ein Bogenstapel
S ist auf einer Stapeltragplatte 5 des Hauptstapelhubwerkes 2 mittels
einer Palette P eingesetzt. Das Hauptstapelhubwerk 2 ist mit strichlierten Linien
dargestellt und weist beiderseits des Bogenanlegers 1 d.h. an jeder Gestellseitenwand
10 eine Hubkette 6 sowie eine Hubwerksschiene 7 und Tragelemente 8
für die Stapeltragplatte 5 auf. Die Tragelemente 8 enthalten eine Traverse, die in
Längsrichtung des Bogenanlegers 1 angeordnet und mit Auflagen für die Stapeltragplatte
5 versehen ist. Die Stapeltragplatte 5 ist bis auf den Boden absenkbar
und ist mit einer Anfahrkante für das Befahren mit einem Stapeltransportmittel
versehen. Damit kann eine Transportpalette P einfach auf der Stapeltragplatte 5
im Bogenanleger 1 zur Verarbeitung bereitgestellt werden.1 shows a
In Fig. 2 ist die Anbringung der Stapeltragplatte 5 am Stapelhubwerk 2 dargestellt.
Die Stapeltragplatte 5 ist dazu mit seitlich überstehenden Ausrichtschienen 9 versehen,
die in Querrichtung zum Bogenanleger 1 angeordnet in die Tragelemente
8 hineinreichen und dort verschiebbar gelagert sind. Die Ausrichtschienen 9 sind
so ausgebildet, daß die Stapeltragplatte 5 in der tiefsten Stellung der Tragelemente
8 am Stapelhubwerk 2 auf dem Boden aufliegt. Auf der Stapeltragplatte 5
ist eine Transportpalette P abgesetzt, die beispielsweise einen Bogenstapel S
tragen kann. Die Lage des Bogenstapels S relativ zum Bogenanleger 1 ist durch
Verschiebung der Stapeltragplatte 5 einstellbar.2 shows the attachment of the
Wie dargestellt, sind die Tragelemente 8 an den Hubwerksschienen 7 so angeordnet,
daß die Ausrichtschienen 9 der Stapeltragplatte 5 auf diesen aufgesetzt
werden können. Dazu ist an jedem Tragelement 8 eine Ausrichtachse 11 angebracht.
Die Ausrichtachse 11 kann als eine starre Auflageschiene oder auch als
drehbares Element ausgeführt sein. Sinnvoll für eine einfache Bauweise und das
Ausrichten großer Lasten z.B. bei vollem Bogenstapel S ist die Verwendung von
einzelnen gelagerten Rollen an jeder Ausrichtschiene 9.As shown, the
In Fig. 2 nicht dargestellt sind die Ausrichtmittel an sich. Dies kann entsprechend
dem Stand der Technik ein am Tragelement 8 befestigter Motor mit einem Stellgetriebe
sein. Gleichfalls kann ein manuelle Ausrichtung vorgegeben sein. Standardmäßig
wird aber ein Satz Stapelausrichtschienen 20 verwendet, wie er in Fig. 1
dargestellt ist. Die Funktion der Stapelausrichtschienen 20, die auf die vorderen senkrechten
Stapelkanten des Bogenstapels S wirken, wird weiter unten dargestellt. The alignment means per se are not shown in FIG. 2. This can be done accordingly

Möglich ist aber auch die Anordnung einer Ausrichtung entsprechend Fig. 3. Hier
ist die Stapeltragplatte 5 über eine Stellvorrichtung in Form einer Stellspindel 12
mit der Tragvorrichtung 8 verbunden. Solche Stellspindeln 12 können an nur
einer Ecke der Stapeltragplatte 5 angeordnet sein, wenn die Ausrichtschienen 9
an den anderen Ecken der Stapeltragplatte 5 mit einer Geradführung versehen
sind, so daß sich die Stapeltragplatte 5 beim Verschieben nicht verkanten kann.
Möglich ist auch die Anordnung zweier Stellspindeln 12 an beiden Ecken einer
Längsseite der Stapeltragplatte 5, d.h. am Tragelement 8 auf der einen Seite des
Bogenanlegers 1. Auf der gegenüberliegenden Seite d.h. am anderen Tragelement
8 können die oben beschriebenen Ausrichtschienen 9 auf Rollen vorgesehen
sein.However, it is also possible to arrange an alignment according to FIG. 3. Here
is the
Alternativ ist in Fig. 4 die Verwendung eines Tragrahmens 13 zum Anheben von
Stapeltragmitteln vorgesehen. Der Tragrahmen 13 besteht aus mehreren Profilen
16, 17, 18. Der Tragrahmen 13 ist an der Rückseite des Bogenanlegers 1, d.h.
von Seite der Stapelzuführung her, offen und lediglich mit kurzen Auflageschenkeln
18 versehen. Die seitlichen Profile 17 des Tragrahmens 13 sind direkt mit
den Ausrichtschienen 9 verbunden, die wie oben beschrieben auf den Tragelementen
8 des Stapelhubwerkes 2 aufliegen. Weiterhin ist der Rahmen 13 an
seinem vorderen Profilelement 16 zur bogenverarbeitenden Maschine hin mit
einem Führungsansatz 14 versehen, der in eine Ausrichtkulisse 15 am Anlegergestell
eingreift. Die seitliche Verschiebung des Tragrahmens 13 kann sinngemäß
wie die Verschiebung der oben beschriebenen Stapeltragplatte 5 erfolgen.Alternatively, in Fig. 4, the use of a
Mit einem solchen Tragrahmen 13 kann für die Stapelverarbeitung z.B. ein Stapeltisch
mit Rollen verwendet werden. Dieser kann selbständig in den Bogenanleger
1 eingefahren werden, wo ihn der Tragrahmen auf einfachste Weise übernimmt
und zum Abarbeiten durch den Saugkopf 3 anhebt. Hierbei kann auch eine
Zentrierung des Stapeltisches mittels einer Mittenführung im Bogenanleger 1 vorgesehen
sein, um die Vorausrichtung des Bogenstapels S zu erleichtern. Dazu
dient auch die Zentrierung des Tragrahmens 13. Der Führungsansatz 14 ist in
einer Führungskulisse 15 seitlich zentriert, solange sich der Tragrahmen 13 in
Aufnahmeposition am Boden befindet. So kann der Bogenstapel S in einer nach
beiden Seiten gleichermaßen ausrichtbaren Positionierung übernommen werden.With such a supporting
Die Stapelausrichtung in Seitenrichtung wird also von einer zentrierten Position
des Tragrahmens 13, die auch für die Stapeltragplatte 5 vorgesehen sein kann,
aus ausgeführt. Hierzu werden die beiden Stapelausrichtschienen 20 mittels des Antriebes
21 gegen die vorderen senkrechten Kanten des Bogenstapels S gefahren
und halten diesen so seitlich und in Längsrichtung ausgerichtet. Die Stapelausrichtschienen
20 sind mittels des Antriebes 21 sowohl relativ zueinander als auch gemeinsam
in einer Richtung verschiebbar. Damit ist der Bogenstapel S sowohl
quer gehalten als auch quer verschiebbar, wobei er samt Transportpalette und
Stapeltragplatte 5 auf den Ausrichtschienen 9 und den Ausrichtachsen 11 bewegt
wird. Eine Stellvorrichtung wie in Fig. 3 ist dann nicht erforderlich.The stack orientation in the lateral direction is thus from a centered position

Grundsätzlich kann die Führung des Bogenstapels nach Fig. 1 bis 3 und Fig. 4
unterschieden werden. Bei der ersten Version, die eine Stapeltragplatte 5 verwendet,
sind lediglich ebene Stapelausrichtschienen 20 für den Bogenstapel S vorgesehen,
da diese ja mit einer einfachen Transportpalette zusammenarbeiten sollen.
Im zweiten Fall bei Verwendung des rollbaren Stapeltisches kann dieser so ausgebildet
sein, daß an seiner Vorderkante Ausnehmungen vorgesehen sind. In
diese Ausnehmungen können dann die winkelförmigen Stapelausrichtschienen 20 entsprechend
Fig. 4 eingreifen. Dazu steht der Bogenstapel S in diesem Bereich
etwas über den Stapeltisch über. Die Ausnehmungen sind für beide Stapelecken
nur so breit, daß die für die bogenverarbeitende Maschine vorgesehenen minimalen
und maximalen Bogenformate verarbeitet werden können. Damit ist die vordere
Stapelkante noch ausreichend unterstützt.Basically, the sheet stack can be guided according to FIGS. 1 to 3 and FIG. 4
