Description

Die Neuerung bezieht sich auf einen Bogenausleger an Rotationsdruckmaschinen, bei dem die zugeführten Bogen auf einen absenkbaren Ablegetisch zu einem Bogenstapel abgelegt werden, mit einem, bei vollem Bogenstapel einschiebbaren Stabrost als Zwischenstapeleinrichtung, der sich in eingeschobenem Zustand mit seinem vorderen, freien Ende auf einer Abstützung ablegt.The innovation relates to a sheet delivery on rotary printing presses, in which the fed sheets are deposited on a lowerable deposit table to form a sheet stack, with a bar grate that can be inserted when the sheet stack is full, as an intermediate stacking device which, when inserted, has its front, free end on a support discards.

Die DE-PS 35 35 113 zeigt einen derartigen Bogenausleger mit einer absenkbaren Abstützung des Stabrostes. Der Nachteil dieser bekannten Einrichtung ist, daß z.B. bei Verwendung von Europaletten, die größer sind als das maximale Bogenformat, die Abstützung der Zwischenstapeleinrichtung mit der Europalette beim Hochfahren derselben kollidiert. Hierdurch ist die Zwischenstapeleinrichtung in ihrer Funktionsweise erheblich beeinträchtigt. Auch besteht die Gefahr, daß der Zwischenstapel durch Transportmittel für die Bogenzufuhr beschädigt oder verschoben wird, so daß auch hierdurch Aufwand und Kosten entstehen.DE-PS 35 35 113 shows such a sheet boom with a lowerable support of the bar grate. The disadvantage of this known device is that e.g. When using euro pallets that are larger than the maximum sheet format, the support of the intermediate stacking device collides with the euro pallet when the same is being raised. As a result, the function of the intermediate stacking device is considerably impaired. There is also the risk that the intermediate stack will be damaged or shifted by means of transport for the sheet feed, so that this also results in expenditure and costs.

Ausgehend von diesem Stand der Technik ist es die Aufgabe der Neuerung, eine Zwischenstapeleinrichtung mit Abstützung des Stabrostes zu schaffen, die die Funktion der Bogenauslage nicht beeinträchtigt.Based on this state of the art, it is the task of the innovation to create an intermediate stacking device with support of the bar grate, which does not impair the function of the sheet delivery.

Gemäß der Neuerung wird diese Aufgabe dadurch gelöst, daß die Abstützung als Schiene ausgebildet ist, die mittels Stellmittel horizontal aus dem Bereich des Bogenstapels verschiebbar gelagert ist. Wird bei dieser Lösung z.B. im Non-Stop-Betrieb mit einer Palette gearbeitet, die dem Bogenformat entspricht, so besteht die Gefahr einer Kollision nicht. Ist jedoch der Drucker gezwungen, bestimmte Druckaufträge auszuführen, die sodann auf einer Europalette abgelegt werden müssen und die Maschine arbeitet nicht im Non-Stop-Betrieb, so ist die Abstützung aus dem Bereich des Bogenstapels und auch aus dem Bereich der Palette verschoben, so daß der Stapeltisch in die oberste Endlage angehoben werden kann, ohne daß die Palette mit der Abstützung der Zwischenstapeleinrichtung kollidiert.According to the innovation, this object is achieved in that the support is designed as a rail which is mounted horizontally displaceably from the area of the sheet stack by means of adjusting means. With this solution, for example, in Non-stop operation with a pallet that corresponds to the sheet format, so there is no risk of a collision. However, if the printer is forced to carry out certain print jobs that must then be placed on a Euro pallet and the machine does not work in non-stop operation, the support is shifted from the area of the sheet stack and also from the area of the pallet, so that the stacking table can be raised to the uppermost end position without the pallet colliding with the support of the intermediate stacking device.

In vorteilhafter Ausgestaltung der Neuerung sind die Stellmittel beiderseits der Schiene angeordnet und als Pneumatikzylinder ausgebildet, wobei die Schiene an den Kolbenstangen der Pneumatikzylinder gelagert ist. Hiermit läßt sich das Verschieben der Schiene mit dem Einfahren, bzw. Herausziehen des Stabrostes schaltungstechnisch verknüpfen. Weiterhin sind die Pneumatikzylinder an Trägern gelagert, die bei zunehmender Stapelhöhe des Zwischenstapels absenkbar sind. Dieses Absenken der Zwischenstapeleinrichtung ist insbesondere beim Verarbeiten von dickerem Bogenmaterial erforderlich, um eine gleiche Fallhöhe der abzulegenden Bogen zu erreichen.In an advantageous embodiment of the innovation, the actuating means are arranged on both sides of the rail and are designed as pneumatic cylinders, the rail being mounted on the piston rods of the pneumatic cylinders. With this, the shifting of the rail can be linked in terms of circuitry with the retraction or extraction of the bar grate. Furthermore, the pneumatic cylinders are mounted on supports which can be lowered as the stack height of the intermediate stack increases. This lowering of the intermediate stacking device is necessary in particular when processing thicker sheet material in order to achieve an equal fall height of the sheets to be deposited.

Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung schematisch dargestellt.An embodiment of the innovation is shown schematically in the drawing.

Bei dem in der Zeichnung dargestellten Bogenausleger werden in bekannter Weise die abzulegenden Bogen 1 von Greiferleisten 2, die an einem Kettensystem 3 vorgesehen sind, einem Bogenstapel 4 zugeführt. Der Bogenstapel 4 liegt auf einem nicht dargestellten Ablegetisch auf, der entsprechend der wachsenden Stapelhöhe absenkbar ist. Sobald der Bogenstapel 4 seine volle Höhe erreicht hat, wird er aus der Maschine herausgenommen, ein le res Stapelbrett engelegt und dieses in seine obere Ausgangsposition zur Aufnahme eines neuen Bogenstapels bewegt.In the sheet delivery shown in the drawing, the sheets 1 to be deposited from gripper bars 2, which are provided on a chain system 3, are fed to a sheet stack 4 in a known manner. The sheet stack 4 rests on a not shown table, which can be lowered according to the increasing stack height. As soon as the sheet stack 4 has reached its full height, it is removed from the machine and an empty stack board is laid and moves it into its upper starting position to receive a new stack of sheets.

Für die Zeit des Stapelwechsels wird auf einem einschiebbaren Stabrost 5 ein Zwischenstapel 6 gebildet. Der Stabrost 5 liegt hierbei an seinem hinteren Ende auf einer Traverse 7 auf. Im eingeschobenen Zustand des Stabrostes 5 ist dieser mit seinem vorderen freien Ende auf einer Abstützung 8 abgelegt. Die Abstützung 8 ist hierbei als Schiene 9 ausgebildet, die beiderseits an den Kolbenstangen 10 von Pneumatikzylindern 11 gelagert ist. Durch Ausfahren der Kolbenstangen 10 aus den Pneumatikzylindern 11 läßt sich die Schiene 9 mit der Abstützung 8 nach rechts in die strichpunktiert gezeichnete Stellung bewegen. In dieser Position kann z.B. ohne Benutzung der Zwischenstapeleinrichtung eine Palette auf den Ablegetisch aufgelegt werden und dieser in seine obere Aufnahmeposition bewegt werden, ohne daß die Palette, die über das maximale Bogenformat übersteht, mit der Abstützung 8 kollidiert.For the time of the stack change, an intermediate stack 6 is formed on an insertable bar grate 5. The bar grate 5 rests on a traverse 7 at its rear end. In the inserted state of the bar grate 5, its front free end is placed on a support 8. The support 8 is designed here as a rail 9, which is mounted on both sides of the piston rods 10 of pneumatic cylinders 11. By extending the piston rods 10 out of the pneumatic cylinders 11, the rail 9 can be moved with the support 8 to the right into the position shown in broken lines. In this position e.g. without using the intermediate stacking device, a pallet is placed on the lay-down table and the latter is moved into its upper receiving position without the pallet, which survives the maximum sheet format, colliding with the support 8.

Die Pneumatikzylinder 11 auf beiden Seiten des Bogenstapels sind an Trägern 12 gelagert, an denen auch die Traverse 7 befestigt ist. Die Träger 12 sind mit einer Führung 13 versehen, die in einer Rollagerung 14 geführt sind. Bei zunehmender Stapelhöhe des Zwischenstapels 6 kann der Träger 12 und mit diesem der Stabrost 5 und der Zwischenstapel 6 über eine nicht dargestellte Hubeinrichtung vertikal abgesenkt werden. Insbesondere bei dickem Bogenmaterial und hoher Maschinengeschwindigkeit ist dieses Absenken für den Non-stop-Betrieb erforderlich.The pneumatic cylinders 11 on both sides of the sheet stack are mounted on supports 12, to which the cross member 7 is also attached. The carriers 12 are provided with a guide 13 which are guided in a roller bearing 14. As the stack height of the intermediate stack 6 increases, the carrier 12 and with it the bar grate 5 and the intermediate stack 6 can be lowered vertically by means of a lifting device (not shown). This lowering is necessary for non-stop operation, especially with thick sheet material and high machine speeds.
