Abstract

A device for conveying and stacking sheets of paper has a first conveying unit receptive of sheets for stacking and a second conveying unit downstream of the first conveying unit for removing a stack and wherein the units include upper and lower belts. A single upper belt is associated with two lower belts for the two units and the upper belt is alternately coupled for movement with one or the other of the two lower belts at the same speed as the lower belt to which it is coupled to effect either the stacking of the sheets or the movement of the stack.

Description

Die Erfindung betrifft eine Bogentransport- und -stapeleinrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a sheet transport and stacking device with the features of the preamble of claim 1.

Derartige Einrichtungen sind bekannt und zum Beispiel in der DE-OS 31 14 414 beschrieben. Diese bekannten Einrichtungen sind mit separaten Oberbändern für den Abtransport des fertigen Bogenstapels ausgerüstet, deren Unterbringung aus Platzgründen auf kleinstem Raum erfolgen muß. In der Regel ist nur Platz für ein Band pro Stapel, das den Stapel einseitig erfaßt. Daraus ergibt sich der Nachteil, daß sich die Bogenstapel beim Abtransport verlagern oder verschieben können. Dies macht ein nachträgliches Ausrichten des Stapels erforderlich, was jedoch nicht immer gelingt.Such devices are known and described for example in DE-OS 31 14 414. These known devices are equipped with separate upper belts for the removal of the finished sheet stack, which must be accommodated in the smallest space for reasons of space. As a rule, there is only space for one band per stack that grips the stack on one side. This results in the disadvantage that the sheet stacks can shift or shift during removal. This makes subsequent alignment of the stack necessary, but this is not always possible.

Der Erfindung liegt nun die Aufgabe zugrunde, den konstruktiven Aufwand für die zum Abtransport des Bogenstapels erforderlichen Oberbänder zu verringern, gleichzeitig aber ein geordnetes Abtransportieren des Bogenstapels zu ermöglichen.The invention is based on the object of reducing the structural outlay for the upper belts required for the removal of the sheet stack, but at the same time allowing the sheet stack to be removed in an orderly manner.

Zur Lösung dieser Aufgabe werden bei einer Bogentransport-und -stapeleinrichtung der eingangs genannten Gattung erfindungsgemäß die im Anspruch 1 gekennzeichneten Merkmale vorgeschlagen. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet.To achieve this object, the features characterized in claim 1 are proposed according to the invention in a sheet transport and stacking device of the type mentioned at the outset. Advantageous refinements are characterized in the subclaims.

Kern der Erfindung ist der Gedanke, das für den Transport der Bogen vorhandene obere Band auch beim Abtransport des Bogenstapels aus der Stapeleinrichtung einzusetzen. Dies wird dadurch ermöglicht, daß das obere Band wechselweise vom Antrieb des unteren Bandes, auf dem die Bogen herantransportiert werden, und zwar mit der gleichen Geschwindigkeit wie dieses bewegt wird, und beim Abtransport des fertigen Bogenstapels dann in synchronem Gleichlauf von dem Antrieb des unteren Bandes, auf dem der Bogenstapel liegt. Ein konstruktiver Mehraufwand für zusätzliche obere Bänder zum Abtransport des Bogenstapels, wie er bei vorhandenen Anlagen notwendig war, entfällt bei der erfindungsgemäßen Einrichtung.The essence of the invention is the idea of using the upper belt available for the transport of the sheets also when the sheet stack is being removed from the stacking device. This is made possible by the fact that the upper belt is moved alternately by the drive of the lower belt, on which the sheets are transported, at the same speed as this, and then, when the finished stack of sheets is removed, in synchronous synchronism with the drive of the lower belt on which the stack of sheets lies. A constructive additional effort for additional upper belts for the removal of the sheet stack, as was necessary in existing systems, does not apply to the device according to the invention.

Um den Bogenstapel zum Abtransport mit dem oberen Band in Kontakt zu bringen ist bei herkömmlichen Anlagen das untere Band hebbar ausgebildet. Nach einer vorteilhaften Ausgestaltung der Erfindung ist es jedoch auch möglich, das obere Band mittels einer Stützplatte nach unten bis zum Kontakt mit dem Bogenstapel zu bewegen. Dazu ist die Stützplatte heb- und senkbar gelagert. Selbstverständlich können bei der Relativbewegung der für den Abtransport des Bogenstapels dienenden unteren und oberen Bänder auch beide aufeinander zu bewegt werden.In order to bring the stack of sheets into contact with the upper belt for transport, the lower belt is designed to be liftable in conventional systems. According to an advantageous embodiment of the invention, however, it is also possible to move the upper band downwards by means of a support plate until it comes into contact with the sheet stack. For this purpose, the support plate can be raised and lowered. Of course, the relative movement of the lower and upper belts used to transport the stack of sheets can also be moved towards one another.

Anhand des in der Zeichnung dargestellten Ausführungsbeispiels wird die Erfindung näher erläutert.On the basis of the embodiment shown in the drawing, the invention is explained in more detail.

Auf dem unteren Band 8 kommen die Papierbögen 9 überlappt an der Bogenstapeleinrichtung an. Um ein geordnetes Überführen der Bogen 9 von dem unteren Band 8 auf den Bogenstapel 6 zu gewährleisten, ist das obere Band 1 angeordnet, das die Bogen 9 im Bereich des Endabschnitts des unteren Bandes 8 erfaßt.On the lower belt 8 the sheets of paper 9 arrive at the sheet stacking device in an overlapping manner. In order to ensure an orderly transfer of the sheets 9 from the lower belt 8 to the sheet stack 6, the upper belt 1 is arranged, which grips the sheets 9 in the region of the end section of the lower belt 8.

Während des Stapelbetriebes ist das obere Band 1 über die Kupplung 2 mit dem Antrieb 3 des unteren Bandes 8 gekoppelt und wird mit derselben Geschwindigkeit wie das untere Band 8 bewegt. Dieser Gleichlauf des oberen Bandes 1 mit dem unteren Band 8 ist wichtig.-für einen geordneten Weitertransport der Bogen 9 zur Stapelstelle.During the stacking operation, the upper belt 1 is coupled to the drive 3 of the lower belt 8 via the clutch 2 and is moved at the same speed as the lower belt 8. This synchronism of the upper belt 1 with the lower belt 8 is important for an orderly further transport of the sheets 9 to the stacking point.

Wenn die vorgesehene Höhe des Stapels 6 erreicht ist, wird das oberen Band 1 über die Kupplung 2 von dem Antrieb 3 des unteren Bandes 8 gelöst. Der Ablegetisch mit dem unteren (Stapeltransport-)Band 7 wird angehoben, bis der Stapel 6 gegen das obere Band 1 gedrückt wird. Durch die abgesenkte Stützplatte 5 kann das obere Band 1 nicht ausweichen. Der Stapel 6 ist so zwischen dem unteren Band 7 und dem oberen Band 1 eingespannt.When the intended height of the stack 6 is reached, the upper belt 1 is released from the drive 3 of the lower belt 8 via the coupling 2. The deposit table with the lower (stack transport) belt 7 is raised until the stack 6 is pressed against the upper belt 1. Due to the lowered support plate 5, the upper band 1 cannot escape. The stack 6 is thus clamped between the lower band 7 and the upper band 1.

Über die Kupplung 10 wird die Antriebsrolle 11 für das obere Band 1 an den Antrieb 4 für das untere Band 7 angekoppelt. Zwischen im Gleichlauf durch den Antrieb bewegten Bändern 1 und 7 wird der Stapel 6 in Pfeilrichtung 12 abgefördert.The drive roller 11 for the upper belt 1 is coupled to the drive 4 for the lower belt 7 via the clutch 10. The stack 6 is conveyed in the direction of the arrow 12 between belts 1 and 7 which are moved in synchronism by the drive.

Nach Entfernen des Stapels 6 aus der Stapeleinrichtung wird über die Kupplung 10 die Antriebsrolle 11 des oberen Bandes 1 von dem Antrieb 4 für das untere Band 7 gelöst und über die Kupplung 2 wieder an den Antrieb 3 für das untere (Bogentransport-) Band 8 angekoppelt. Die weitere Zuführung von Bogen 9 zur Stapelstelle kann dann erneut beginnen, nachdem zuvor das untere Band 7 in die Ausgangslage abgesenkt und die Stützplatte 5 angehoben worden ist.After the stack 6 has been removed from the stacking device, the drive roller 11 of the upper belt 1 is released from the drive 4 for the lower belt 7 via the coupling 10 and coupled again to the drive 3 for the lower (sheet transport) belt 8 via the coupling 2 . The further feeding of sheets 9 to the stacking point can then begin again after the lower belt 7 has been lowered into the starting position and the support plate 5 has been raised.
