Abstract
Description
Die Erfindung bezieht sich auf einen Anlegetisch zum taktmäßigen Fördern von Bogen zu einer Bogen verarbeitenden Maschine nach den gattungsbildenden merkmalen des Anspruchs 1.The invention relates to a feed table for cyclical conveying of sheets to a sheet processing machine according to the generic features of claim 1.
Bei derartigen bekannten Anlegetischen kann es aus verschiedenen Gründen bei einer Unterdruckbeaufschlagung zu einem Unterdruckverlust führen, wenn ein Teil der Saugöffnungen der Saugbänder während des Betriebs des Anlegetischs nicht durch die geförderten Bogen abgedeckt und damit verschlossen werden. Dies ist z.B. der Fall, wenn die geförderten Bogen eine geringere Breite haben, als es der Abstand zwischen den äußeren Saugbändern ist. Dabei kann es sich sowohl um Förderung im Schuppenstrom als auch um Einzelbogenförderung handeln.In such known feed tables, it can consist of different Reasons for applying a vacuum lead to a loss of pressure if part of the Suction openings of the suction belts during the operation of the Feed table not covered by the funded sheets and be closed with it. This is e.g. the Case when the conveyed sheets have a smaller width than the distance between the outer suction belts is. It can be both funding in Scale flow as well as single sheet promotion.
Bei Einzelbogenförderung kommt es weiterhin zu einem Unterdruckverlust in den Bereichen zwischen den Bogen, in denen die Saugöffnungen der Saugbänder offenliegen.In the case of single sheet conveyance, there is still one Loss of pressure in the areas between the arches, in which the suction openings of the suction belts are exposed.
Ein hoher Unterdruckverlust tritt auch bei Förderung eines einzelnen Bogens durch die vor und hinter dem Bogen offenen Saugöffnungen auf. Der gleiche ungünstige Effekt tritt bei dem ersten und dem letzten Bogen eines Schuppenstroms auf.A high vacuum loss also occurs during delivery a single arch through the front and back of the arch open suction openings. The same inconvenient Effect occurs on the first and last sheets Scale flow.
Diese Unterdruckverluste führen zu einer Reduzierung der Kraft, mit der die Bogen an den Saugbändern gehalten werden, die so gering werden kann, daß die Bogen nicht mehr verschiebungsfrei auf den Saugbändern gehalten werden.These negative pressure losses lead to a reduction the force with which the sheets are held on the suction belts be so low that the bow no longer held on the suction belts without displacement become.
Darüberhinaus ist die Haltekraft unterschiedlich groß abhängig von dem Umfang der Abdeckung der Saugöffnungen durch die Bogen.In addition, the holding force is different depending on the extent of the cover of the suction openings through the arch.
Aus der EP-0-776-846 A2 ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 zur Förderung von Bogen bekannt. Diese Vorrichtung weist eine Reihe von Saugkammern mit Öffnungen an ihrer Oberseite auf, die über die ganze Breite eines Fördertisches ragend hintereinander angeordnet sind. Jeder Saugkasten ist mit einer Luftversorgung verbunden, die über Schaltventile von einem gemeinsamen Lufterzeuger bedient werden. Die Saugkästen können unterschiedlich mit Luft versorgt werden, wobei sie parallel zueinander an die gleiche gemeinsame Lufterzeugungsanlage angeschlossen sind.From EP-0-776-846 A2 a device according to the preamble of claim 1 for conveying sheets is known. This The device has a series of suction chambers with openings on their top that over the entire width of a conveyor table are arranged one behind the other. Everyone Suction box is connected to an air supply that is switched by a common switching valve Air generators are operated. The suction boxes can be different with air are supplied, being parallel to each other to the same common air generation system are connected.
In der EP-0-453-790 A1 wird eine Vorrichtung zum Fördern von Druckbogen beschrieben. Diese weist einen Fördertisch für eine Bogen verarbeitende Maschine auf, von dem taktmäßig Bogen an die Bogen verarbeitende Maschine abgeliefert werden. Der Fördertisch weist in einer Ausführungsform zwei in Bogenlaufrichtung hintereinander angeordnete Saugkammern auf, die über die Breite des Fördertisches reichen und an ihrer Oberseite Öffnungen zur Versorgung von Saugbändern mit Saugluft aufweisen. Jede Saugkammer ist mit ein in einem eigenen Lufterzeuger verbunden. Die Länge der Saugkammern überstreicht dabei einen großen Förderbereich und die ganze Tischbreite.EP-0-453-790 A1 describes a device for conveying printed sheets. This has a conveyor table for a sheet processing machine, of which clockwise Sheets are delivered to the sheet processing machine. The conveyor table in one embodiment has two arranged one behind the other in the direction of sheet travel Suction chambers that extend across the width of the conveyor table and on their top Have openings for supplying suction belts with suction air. Every suction chamber is connected with one in its own air generator. The length of the suction chambers covers a large conveying area and the entire table width.
Aus der US PS 4 645 069 ist ein Vakuum-Saugtransporteur bekannt. Er weist einen über die Länge eines Fördertisches reichenden Förderbereich auf. Der Förderbereich ist mit einzelnen Saugkammern versehen, über die ein mit Saugöffnungen versehenes Saugband geführt wird. Alle Saugkammern sind parallel zueinander an eine gemeinsame Luftversorgung angeschlossen und können über Steuereinrichtungen unterschiedlich mit Saugluft versorgt werden.A vacuum suction conveyor is known from US Pat. No. 4,645,069. He transfers one the length of a conveyor area extending conveyor table. The funding area is with individual Provide suction chambers over which a suction belt provided with suction openings to be led. All suction chambers are parallel to each other to a common air supply connected and can be controlled differently with suction air via control devices be supplied.
Aufgabe der Erfindung ist es daher einen Anlegetisch der eingangs genannten Art zu schaffen, durch den die Bogen an jeder Stelle des Anlegetischs mit der jeweils optimalen Haltekraft auf den Saugbändern gehalten werden. The object of the invention is therefore a feed table to create of the type mentioned by which the Sheet at each point on the feed table with the optimal holding force can be held on the suction belts.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention solved with the characterizing features of claim 1.
Diese Ausbildung ermöglicht es die Haltekraft, mit der die Bogen auf den Saugbändern gehalten werden an jeder Stelle des Anlegetischs auf ein Optimum einzustellen. Dabei können nach einem Bereich hoher erforderlicher Haltekraft, in dem eine Unterdruckbeaufschlagung erfolgt, zum plötzlichen Erreichen einer geringen Haltekraft nach Beaufschlagungsbereichen mit hoher Unterdruckbeaufschlagung Beaufschlagungsbereiche mit geringer Unterdruckbeaufschlagung oder sogar mit Druckbeaufschlagung folgen. Dies ist z.B. im Endbereich des Anlegetischs von Vorteil, in dem eine Seitenausrichtung erfolgen soll, die ein Verschieben der auzurichtenden Bogen erfordert, während die unmittelbar folgenden Bogen noch unverschiebbar auf den Saugbändern gehalten werden müssen.This training enables the holding force with which the sheets on the suction belts are held on everyone Adjust the position of the feed table to an optimum. Doing so may require a high area Holding force in which a vacuum is applied, to suddenly reach a low holding force according to exposure areas with high negative pressure Areas of application with less Pressurized or even pressurized consequences. This is e.g. in the end area of the feed table beneficial in a side orientation should take place, which is a shift of the to be aligned Bow required while the immediately following bow still held immovable on the suction belts Need to become.
Auch eine Variation der Druck- und/oder Unterdruckbeaufschlagung in Abhängigkeit der Bogenqualität der jeweils verarbeiteten Bogen ist möglich. So benötigen leichte Bogen eine andere Haltekraft als Bogen grösserer Steifigkeit. Auch ist bei Bogen großer Luftdurchlässigkeit ein anderes Unterdruckniveau sinnvoll als bei Bogen geringer Luftdurchlässigkeit.Also a variation of the pressure and / or negative pressure depending on the sheet quality of each processed bow is possible. So need it light arches have a different holding force than arches larger Rigidity. There is also great air permeability with bows a different vacuum level makes sense than for sheets with low air permeability.
Ungewollte Unterdruckverluste bei dem ersten und dem letzten Bogen werden durch die erfindungsgemäße Ausbildung ebenfalls vermieden, da kein Kurzschluß der aktiven Beaufschlagungsbereiche zur Atmosphäre erfolgt.Unintended negative pressure losses with the first and the last bow are through the inventive training also avoided since there is no short circuit of the active Areas of exposure to the atmosphere occur.
Die Druck- und/oder Unterdruckbeaufschlagung der Beaufschlagungsbereiche kann in Abhängigkeit ihrer Abdeckung durch geförderte Bogen ansteuerbar sein, sodaß Unterdruck- oder Druckverluste durch Kurzschluß mit der Atmosphäre und damit eine Veränderung der Haltekraft der Bogen auf den Saugbändern vermieden wird.The pressure and / or negative pressure application of the application areas can depend on their coverage can be controlled by conveyed sheets, so that negative pressure or pressure loss due to short circuit with the atmosphere and thus a change in the holding power of the Arch on the suction belts is avoided.
Darüberhinaus wird die für die Erzeugung des Drucks oder des Unterdrucks aufzubringende Energie auf das mindest erforderliche Maß reduziert.In addition, it is used for generating the pressure or the energy to be applied to the vacuum minimum required size reduced.
Verändern sich durch die Förderbewegung der Bogen die von den Bogen abgedeckten und nicht abgedeckten Beaufschlagungsbereiche, so kann eine permanent sich ändernde Ansteuerung der Beaufschlagung der Beaufschlagungsbereiche erfolgen, sodaß immer nur die gerade von einem Bogen abgedeckten Beaufschlagungsbereiche mit Druckoder Unterdruck beaufschlagt werden. Dies ist z.B. auch am Anfang und am Ende eines Bogenstromes von Vorteil.Change through the conveying movement of the bow areas of exposure covered and not covered by the arches, so can a permanently changing Control of the application of the application areas done, so that only the one Arc covered areas with pressure or Vacuum can be applied. This is e.g. also an advantage at the beginning and at the end of an arc stream.
Die Beaufschlagungsbereiche können mit einem Druckund/oder Unterdruck unterschiedlichen Druckniveaus beaufschlagbar ansteuerbar sein.The application areas can be with a pressure and / or Different pressure levels can be applied to negative pressure be controllable.
Um bei Förderung im Schuppenstrom jeden Bogen an jeder Stelle des Transportwegs mit seiner optimalen Haltekraft auf den Saugbändern zu halten, sind die Beaufschlagungsbereiche mit einem etwa einem Schuppenabstand eines zu fördernden Schuppenstroms von Bogen entsprechenden Abstand angeordnet .In order to convey every bend to everybody in the shingled stream Place of the transport route with its optimal holding force To keep on the suction belts are the areas of exposure with about a scale distance of a scale stream to be conveyed from Bogen corresponding Distance arranged.
Will man dabei in Schuppenströmen unterschiedlichen Schuppenabstands fördern können, so können die Beaufschlagungsbereiche mit einem etwa einem geringst möglichen Schuppenabstand eines zu fördernden Schuppenstroms entsprechenden Abstand von Bogen angeordnet sein. Do you want different in shingled streams? Can promote scale spacing, so the impact areas with about the least possible Scale distance of a scale flow to be conveyed appropriate distance from the arc his.
Natürlich ist es durch die erfindungsgemäße Ausbildung grundsätzlich möglich sowohl im Schuppenstrom als auch im Einzelbogenstrom zu fördern.Of course it is due to the training according to the invention basically possible both in the shingled stream and to promote in single sheet flow.
Um die einzelnen Beaufschlagungsbereiche exakt und rasch wechseln ansteuern zu können, ist jedem Beaufschlagungsbereich ein Druck- und/oder Unterdruckerzeuger zugeordnet . Damit wird auch das Volumen, welches unter Unterdurck- oder Druck gesetzt werden soll, gering gehalten und somit der Druck- oder Unterdruck schnell auf- bzw. abbaubar.To the individual application areas exactly and To be able to switch quickly to any application area a pressure and / or vacuum generator assigned. So that also the volume, which are put under pressure or pressure should be kept low and thus the pressure or vacuum can be assembled and disassembled quickly.
Die erfindungsgemäße Ausgestaltung der Beaufschlagungsbereiche besteht darin, daß die Beaufschlagungsbereiche durch unter der Tischoberfläche angeordnete druck- und/oder unterdruckbeaufschlagbare Kammern gebildet sind, die über Durchlässe in der Tischoberfläche mit der Unterseite der Saugbänder verbunden sind.The configuration of the application areas according to the invention is that the areas of exposure to arranged under the table surface pressure and / or pressurizable chambers are formed which through openings in the table surface with the bottom the suction belts are connected.
Dabei kann jedem Beaufschlagungsbereich ein separat ansteuerbarer Ventilator zur Druck- und/oder Unterdruckbeaufschlagung zugeordnet sein. Each application area can be controlled separately Fan for pressurizing and / or negative pressure be assigned.

Umlenkrollen 4 und Rollen 5 sind um quer zur Förderrichtung
2 sich erstreckende Achsen drehbar, wobei die
abgabeseitigen Umlenkrollen 4 drehbar antreibbar sind

In jeder Kammer 6 ist ein Ventilator 8 angeordnet, der reversierbar antreibbar ist und je nach Drehrichtung einen Druck oder einen Unterdruck in der Kammer 6 erzeugt. Über eine Ansteuerung der Ventilatoren 8 mit höherer oder niedrigerer Drehzahl kann ein unterschiedliches Druckniveau in den Kammern 6 erzeugt werden.A fan 8 is arranged in each chamber 6 is reversibly driven and depending on the direction of rotation generates a pressure or a negative pressure in the chamber 6. By controlling the fans 8 with higher or lower speed can be different Pressure level in the chambers 6 are generated.
Eine andere Möglichkeit zur Erzeugung eines unterschiedlichen Druckniveaus in der Kammer besteht darin, daß die Kammer eine nach außen führende öffnung aufweist, deren Durchgangsquerschnitt variabel zwischen völlig geschlossen und vollständig geöffnet einstellbar ist. Durch den Kurzschluß zur Außenluft ist trotz konstanter Drehzahl der Ventilatoren eine Einstellung des Druckniveaus in den Kammern möglich.Another way to create a different one Pressure levels in the chamber is that the chamber has an opening leading to the outside, whose passage cross section is variable between fully closed and fully open adjustable is. Due to the short circuit to the outside air is despite constant Speed of the fans an adjustment of the Pressure levels in the chambers possible.
Da jeder Ventilator 8 bei dem dargestellten Ausführungsbeispiel separat ansteuerbar ist, ist in jeder Kammer 6 separat ein Druck oder Unterdruck erzeugbar.Since each fan 8 in the illustrated embodiment can be controlled separately, is in each Chamber 6 separately generate a pressure or negative pressure.
