Abstract
Description
Die Erfindung betrifft eine Puderabsaugeinrichtung an Druckmaschinen, insbesondere zur Absaugung von Puder an Bogenleiteinrichtungen von Bogenoffsetdruckmaschinen.The The invention relates to a powder extraction device on printing machines, in particular for the extraction of powder on sheet guiding devices of sheet-fed offset printing machines.
Der Transport der Bedruckstoffe innerhalb von Druckmaschinen erfolgt u. a. auch mittels Leiteinrichtungen. So werden beispielsweise die bedruckten Bogen in Bogenoffsetdruckmaschinen mittels Bogenleiteinrichtungen zur Stapeleinrichtung transportiert. Bei den dafür zur Anwendung kommenden pneumatischen Bogenleiteinrichtungen werden die Bogen auf der Oberfläche von sogenannten Saugkästen gefördert.Of the Transport of the substrates is done within printing presses u. a. also by means of guiding devices. For example, the printed sheets in sheet-fed offset printing presses using sheet guiding devices transported to the stacker. At the for Application coming pneumatic sheet guiding devices are the Arch on the surface of so-called suction boxes promoted.
Eine
derartige Leiteinrichtung wird in der
Die die Oberfläche der Saugkästen bildenden Bogenleitbleche sind mit zur Ansaugung der Bogen dienenden Öffnungen versehen. Der Saugkasten in seiner Gesamtheit setzt sich aus dem Bogenleitblech und dem Gehäuse zusammen. Sie bilden im zusammengesetzten Zustand einen Hohlraum. Am Boden des Gehäuses sind Luftabsaugbaugruppen eingebracht. Häufig sind diese Luftabsaugbaugruppen als Axialventilatoren ausgebildet. Mittels dieser Axialventilatoren wird die im Hohlraum befindliche Luft abgesaugt und dadurch im Hohlraum ein Unterdruck erzeugt. Der entstandene Unterdruck verursacht einen Druckausgleich zwischen dem Luftdruck der Umgebungsluft und dem Hohlraum. Bei diesem Druckausgleich strömt Luft aus der Umgebung in den Hohlraum. Befindet sich der Bogen über den Öffnungen des Bogenleitbleches, so findet eine Ansaugung des durch Greiferwagen gezogenen Bogens statt. Während des Transportvorganges werden die bedruckten Bogen durch gegenüber der Oberfläche der Bogenleiteinrichtung angeordneten Pudersprühvorrichtungen mit Puder beaufschlagt. Bei der Puderauftragung sind die Pudersprühvorrichtungen ständig in Funktion.The the surface of the suction boxes forming sheet baffles are provided with serving for suction of the arc openings. The suction box in its entirety consists of the sheet guide plate and the housing together. They make up in the composite Condition a cavity. At the bottom of the housing Luftabsaugbaugruppen are introduced. Often these Luftabsaugbaugruppen are axial fans educated. By means of these axial fans is in the cavity sucked air sucked and thereby in the cavity a negative pressure generated. The resulting negative pressure causes a pressure equalization between the atmospheric pressure of the ambient air and the cavity. At this pressure equalization air from the environment flows into the cavity. is the arch over the openings of the sheet guide plate, so finds a suction of drawn by gripper carriage bow instead of. During the transport process, the printed Arch through against the surface of the sheet guiding device arranged powder spray devices applied with powder. In powder application are the powder spray devices constantly in function.
Nachteilig ist, dass sich bei der Puderauftragung aufgrund von Verwirbelungen eine puderhaltige Atmosphäre ausbildet und Ablagerungen von in die Umluft geblasenen Puder zu Schäden der Maschinenbaugruppen führen können. Beeinträchtigungen der elektronischen (z. B. kontaktbehafteten) Baugruppen sind ebenfalls möglich. Weiterhin stellen hohe Konzentrationen der mit organischen Substanzen der Pudermaterialien vermischten Puder/Luftgemische sicherheitstechnische Gefahren (z. B. Verpuffungen) dar.adversely is that in the powder application due to turbulence creates a powdery atmosphere and deposits of blown into the circulating air powder to damage the machine assemblies being able to lead. Impairments of the Electronic (eg contact-based) assemblies are also possible. Furthermore, high concentrations of Powder materials organic substances mixed powder / air mixtures safety-related hazards (eg deflagration).
Die Aufgabe der Erfindung besteht deshalb in der Schaffung einer Puderabsaugeinrichtung für Druckmaschinen, die eine Beseitigung des an Bogenleiteinrichtungen aufgewirbelten Puder/Luftgemisches und/oder abgelagerten Pudermateriales ermöglicht ohne dabei eine Qualitätsbeeinflussung der Bedruckstoffe während des Transportvorganges zu verursachen.The The object of the invention is therefore to provide a powder extraction for printing presses, which eliminates the need for sheet guiding equipment fluidized powder / air mixture and / or powdered material deposited allows quality without affecting quality to cause the substrates during the transport process.
Gelöst wird diese Aufgabe durch die Puderabsaugeinrichtung mit den durch Patentanspruch 1 beschriebenen technischen Merkmalen. Vorteilhafte Weiterbildungen der erfindungsgemäßen Lösung werden mit den Merkmalen der Patentansprüche 2 bis 5 beschrieben. Durch die Schaffung der erfindungsgemäßen Puderabsaugeinrichtung für Bogenleiteinrichtungen an Druckmaschinen ist es möglich, zu verhindern, dass bei einer Puderauftragung während des Transportes das durch die Ansaugung angesaugte Puder/Luftgemisch in die Umgebungsluft abgegeben wird. Puderablagerungen im unmittelbaren Bereich der Druckmaschine und damit verbundene Beschädigungen von Maschinenbaugruppen, insbesondere von elektronischen Steuerungen, können dadurch vermieden werden. Sicherheitstechnischen Gefahren wie beispielsweise Verpuffungen kann mit der Einrichtung entgegengewirkt werde.Solved This object is achieved by the powder suction with the Claim 1 described technical features. Advantageous developments the solution according to the invention are with the features of claims 2 to 5 described. By providing the powder extraction device according to the invention For sheet guiding devices on printing presses, it is possible to prevent powder during powder application Transport the sucked by the suction powder / air mixture is discharged into the ambient air. Powder deposits in the immediate Area of the printing press and related damage of machine assemblies, in particular of electronic controls, can be avoided. Safety hazards such as deflagration can be counteracted with the device will.
Nachfolgend soll die erfindungsgemäße Puderabsaugeinrichtung anhand eines Ausführungsbeispieles näher erläutert werden.following should the powder extraction according to the invention explained in more detail with reference to an embodiment become.
