Definitions
- the invention relates to a drying device for a sheet processing machine, in particular for a sheet-fed printing machine or a sheet-coating machine, according to the preamble of claim 1.
- such a drying device is known as a blow box, which should allow a uniform drying of ink on sheets or sheets and a tensioning effect transverse to the conveying direction.
- the blow box has a substrate surface facing the substrate with a plurality of depressions, wherein the recesses protrude from the interior of the blow box in the direction of printing material and in each case inclined to the conveying plane of the printing material against the conveying direction blowing openings.
- blowpipes are known in a printing press, which are arranged at intervals to each other transversely to the conveying direction of the sheet material.
- the blowpipes are connected to air connections and have openings from which the dry air flows out onto the sheet material.
- the disadvantage here is that the transverse to the conveying direction linearly directed to the sheet material dry air has a negative effect on the sheet run.
- the free end of the sheet tends to wavy and in extreme cases to whip-like movements, so that Abschmier bine or marks can occur.
- the invention has for its object to provide a drying device of the type mentioned, which avoids the disadvantages mentioned, which ensures a quiet sheet travel, especially at higher machine speeds and has a simple structure.
- a first advantage of the drying device is based on the fact that the dry air (thermal air) acts on the sheet material in a planar manner by the drying device and that a smooth sheet travel can be achieved even at higher processing speeds (> 10,000 sheets per hour).
- the dryer device has a planar guide surface (lower plate) associated with the printing substrate, with blow openings or blowing nozzles, so that no components protrude and smearing effects or markings can be avoided. Due to the planar guide surface, which is arranged substantially parallel to a conveying plane of the sheet material, the recoverable by dry air heat input in the sheet material is significantly improved and the drying process is shortened overall.
- a sheet processing machine preferably a sheet-fed rotary printing press or sheet-fed rotary printing machine, has in the conveying direction a downstream of the printing units and / or coating units boom.
- the boom follows a sheet guiding cylinder 1, for example a coating unit, and has inter alia a conveyor system 2 endlessly revolving around deflection elements 2 with gripper systems 3 arranged at intervals at intervals for the sheet transport.
- the sheet material 8 fixed with the leading edge in the gripper closure is fed by the gripper systems 3 in the conveying direction 11 via a sheet brake to a delivery stack 6 in a conveying plane and to stops stored.
- a blast air device 5 is arranged above this in a field.
- the boom further has sheet guiding devices 7, which are arranged below the conveying plane for the sheet material 8 at a defined distance from the sheet material 8.
- the sheet guiding devices 7 preferably have double-walled sheet guiding devices 7 in the area of drying devices 9, through which a coolant can flow.
- a suction system 10 and a plurality of drying devices 9 are arranged in the delivery arm.
- a first drying device 9 is arranged in the arched area and in the horizontal part of the delivery device a second and third drying device 9 (identical in construction).

- Each drying device 9 has - viewed in the conveying direction 11 - a transversely to the conveying direction 11 arranged first hollow body 15, preferably as a first tube, and a second hollow body 16, preferably as a second tube, on.
- the tubes 15, 16 are end-coupled with a conduit system for the dryer air (thermo-air) supply and preferably extend over the maximum format width.
- Each tube 15, 16 has over its length preferably a plurality of outflow openings 17, which are arranged opposite one another (FIG. 2).
- the outflow openings 17 as a continuous recess in the hollow bodies (tubes) 15, 16 executable.
- the tubes 15, 16 are connected via the format width by a closed top plate 12 and a bottom plate 13 provided with blowing openings 14, side walls 19 delimiting the top and bottom plates 12, 13 at the end.
- a flow channel 20 is formed through the upper and lower plates 12,13 and the side walls 19 is thus in conjunction with the hollow bodies 15, 16 (here the tubes 15,16).
- the tubes 15, 16 are preferably of the same thickness in the outer diameter, so that the upper and lower plates 12, 13 are arranged parallel to one another.
- the blowing openings 14 in the lower plate 13 are designed as through-holes and / or slots and are preferably arranged vertically in the lower plate 13, so that they are directed approximately perpendicular to the conveying plane of the sheet material 8.
- the blowing openings 14 are arranged within the thickness of the lower plate 13.
- the underside of the lower plate 13 facing the conveying plane is thus a planar guide surface for the sheet material 8.
- the blowing apertures 14 are preferably arranged with uniform spacing in the lower plate 13.
- top and bottom plates 12,13 and the side walls 19 are in a training preferably with the tubes 15,16 releasably cohesively, for example by releasable adhesive bonds connected. Alternatively, screw connections can be used.
- the upper and lower plates 12, 13 are led out beyond the tubes 15, 16 and are detachably connected to one another by connecting elements 18 (FIG. 2).
- the connecting elements 18 additionally serve to fasten the drying device 9, for example on a traverse or on a other holding means on the frame of the jib.
- At least one Abschottblech is arranged in the boom within the conveyor system between the upper and lower run.
- the air turbulences influenced by the rotating gripper systems 3 can be reduced and the sheet material 8 is noticeably moved in the conveying direction 11.
- the Abschottblech or the Abschottbleche are arranged in alignment between the lower plates 13 of the drying means 9, so that a continuous guide surface for the sheet material 8 is formed.
- the mode of action is as follows: From a dry air supply, the dry air (thermo-air) is supplied to the pipes 15, 16 as compressed air on the line side and exits from the outflow openings 17, so that the flow channel 20 is supplied with adjustable dry air. From the flow channel 20, the drying air passes through the blowing openings 14 on one side of the conveyed in the conveying direction 11 sheet material 8. The moisture-enriched air is removed by suction system 10 from the sheet processing machine.

Abstract
Description
Die Erfindung betrifft eine Trocknereinrichtung für eine Bogenverarbeitungsmaschine, insbesondere für eine Bogendruckmaschine oder eine Bogenlackiermaschine, nach dem Oberbegriff von Anspruch 1.The invention relates to a drying device for a sheet processing machine, in particular for a sheet-fed printing machine or a sheet-coating machine, according to the preamble of claim 1.
Aus DE 44 06 846 C1 ist eine derartige Trocknereinrichtung als Blaskasten bekannt, welche ein gleichmäßiges Trocknen von Druckfarbe auf Bogen oder Bahnen sowie einen Straffeffekt quer zur Förderrichtung ermöglichen soll. Der Blaskasten weist eine dem Bedruckstoff zugewandte Wandfläche mit einer Vielzahl von Vertiefungen auf, wobei die Vertiefungen aus dem Innenraum des Blaskastens in Richtung Bedruckstoff hervorstehen und jeweils zur Förderebene des Bedruckstoffes gegen die Förderrichtung geneigte Blasöffnungen aufweist.From DE 44 06 846 C1, such a drying device is known as a blow box, which should allow a uniform drying of ink on sheets or sheets and a tensioning effect transverse to the conveying direction. The blow box has a substrate surface facing the substrate with a plurality of depressions, wherein the recesses protrude from the interior of the blow box in the direction of printing material and in each case inclined to the conveying plane of the printing material against the conveying direction blowing openings.
Bei derartigen Ausbildungen ist es nachteilig, dass insbesondere bei der Verarbeitung von Bogenmaterial das freie Ende bei einem unruhigen Bogenlauf mit den hervorstehenden Teilen der Trocknereinrichtung in Kontakt kommt und dort Abschmiereffekte bzw. Markierungen am Bogenmaterial auftreten können. Sollen derartige Markierungen vermieden werden, so muss die Trocknereinrichtung in einem größeren Abstand zum Bedruckstoff angeordnet werden, was wiederum deren Wirkungsgrad reduziert. Des weiteren ist eine derartige Ausbildung relativ aufwendig.In such embodiments, it is disadvantageous that, especially in the processing of sheet material, the free end comes in a troubled sheet run with the protruding parts of the dryer in contact and there Abschmiereffekte or marks on the sheet material can occur. If such markings are to be avoided, then the dryer device must be arranged at a greater distance from the printing material, which in turn reduces its efficiency. Furthermore, such a design is relatively expensive.
Aus DE-PS 692 549 sind Blasrohre in einer Druckmaschine bekannt, welche in Abständen zueinander quer zur Förderrichtung des Bogenmaterials angeordnet sind. Die Blasrohre sind mit Luftanschlüssen verbunden und weisen Öffnungen auf, aus denen die Trockenluft auf das Bogenmaterial ausströmt.DE-PS 692 549 blowpipes are known in a printing press, which are arranged at intervals to each other transversely to the conveying direction of the sheet material. The blowpipes are connected to air connections and have openings from which the dry air flows out onto the sheet material.
Von Nachteil ist hierbei, dass die quer zur Förderrichtung linienförmig auf das Bogenmaterial gerichtete Trockenluft sich negativ auf den Bogenlauf auswirkt. Je nach Verarbeitungsgeschwindigkeit und Elastizitätsmodul des Bogenmaterials neigt insbesondere das freie Bogenende zu wellenförmigen und im Extremfall zu peitschenartigen Bewegungen, so dass Abschmiereffekte oder Markierungen auftreten können.The disadvantage here is that the transverse to the conveying direction linearly directed to the sheet material dry air has a negative effect on the sheet run. Depending on the processing speed and modulus of elasticity of the sheet material in particular, the free end of the sheet tends to wavy and in extreme cases to whip-like movements, so that Abschmiereffekte or marks can occur.
Gemäß DE 33 23 953 C2 ist ein innerhalb des umlaufenden Fördersystems im Ausleger einer Druckmaschine angeordnetes Leitblech bekannt, welches von Greiferwagen erzeugte Luftwirbel vermeiden soll.According to DE 33 23 953 C2 a disposed within the rotating conveyor system in the boom of a printing press baffle is known, which should avoid generated by gripper carriage air vortex.
Der Erfindung liegt die Aufgabe zu Grunde eine Trocknereinrichtung der eingangs genannten Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere bei höheren Maschinengeschwindigkeiten einen ruhigen Bogenlauf gewährleistet und einen einfachen Aufbau aufweist.The invention has for its object to provide a drying device of the type mentioned, which avoids the disadvantages mentioned, which ensures a quiet sheet travel, especially at higher machine speeds and has a simple structure.
Gelöst wird die Aufgabe erfindungsgemäß durch die Ausbildungsmerkmale von Anspruch 1. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The object is achieved according to the invention by the training features of claim 1. Further developments will become apparent from the dependent claims.
Ein erster Vorteil der Trocknereinrichtung ist darin begründet, dass durch die Trocknereinrichtung die Trockenluft (Thermoluft) flächenförmig auf das Bogenmaterial einwirkt und dass ein ruhiger Bogenlauf auch bei höheren Verarbeitungsgeschwindigkeiten (> 10.000 Bogen pro Stunde) erzielbar ist.A first advantage of the drying device is based on the fact that the dry air (thermal air) acts on the sheet material in a planar manner by the drying device and that a smooth sheet travel can be achieved even at higher processing speeds (> 10,000 sheets per hour).
Von Vorteil ist ebenso, dass die Trocknereinrichtung eine den Bedruckstoff zugeordnete ebene Leitfläche (Unterplatte) mit Blasöffnungen bzw. Blasdüsen aufweist, so dass keine Bauteile hervorstehen und Abschmiereffekte bzw. Markierungen vermeidbar sind. Durch die ebene Leitfläche, die im wesentlichen parallel zu einer Förderebene des Bogenmaterials angeordnet ist, ist der mittels Trockenluft erzielbare Wärmeeintrag im Bogenmaterial spürbar verbessert und der Trocknungsprozess ist insgesamt verkürzt.It is likewise advantageous that the dryer device has a planar guide surface (lower plate) associated with the printing substrate, with blow openings or blowing nozzles, so that no components protrude and smearing effects or markings can be avoided. Due to the planar guide surface, which is arranged substantially parallel to a conveying plane of the sheet material, the recoverable by dry air heat input in the sheet material is significantly improved and the drying process is shortened overall.

Eine Bogenverarbeitungsmaschine, bevorzugt eine Bogenrotationsdruckmaschine oder Bogenrotationslackiermaschine, weist in Förderrichtung einen den Druckwerken und/oder Lackwerken nachgeordneten Ausleger auf. Im vorliegenden Beispiel folgt der Ausleger einem Bogenführungszylinder 1, beispielsweise eines Lackwerkes, und weist unter anderem ein um Umlenkelemente 4 endlos umlaufendes Fördersystem 2 mit daran in Abständen angeordneten Greifersystemen 3 für den Bogentransport auf. Mittels Fördersystem 2 wird das mit der Vorderkante im Greiferschluß fixierte Bogenmaterial 8 von den Greifersystemen 3 in Förderrichtung 11 über eine Bogenbremse einem Auslegerstapel 6 in einer Förderebene zugeführt und an Anschlägen abgelegt.
Zur Unterstützung der Bogenablage auf dem Auslegerstapel 6 ist oberhalb dessen in einem Feld eine Blaslufteinrichtung 5 angeordnet. Der Ausleger weist weiterhin Bogenleiteinrichtungen 7 auf, die unterhalb der Förderebene für das Bogenmaterial 8 in einem definierten Abstand zum Bogenmaterial 8 angeordnet sind. Die Bogenleiteinrichtungen 7 weisen bevorzugt im Bereich von Trocknereinrichtungen 9 doppelwandige Bogenleiteinrichtungen 7 auf, welche von einem Kühlmittel durchströmbar sind.A sheet processing machine, preferably a sheet-fed rotary printing press or sheet-fed rotary printing machine, has in the conveying direction a downstream of the printing units and / or coating units boom. In the present example, the boom follows a sheet guiding cylinder 1, for example a coating unit, and has inter alia a

Jede Trocknereinrichtung 9 weist - in Förderrichtung 11 betrachtet - einen quer zur Förderrichtung 11 angeordneten ersten Hohlkörper 15, vorzugsweise als ein erstes Rohr, und einen zweiten Hohlkörper 16, vorzugsweise als ein zweites Rohr, auf. Im vorliegenden Beispiel sind die Rohre 15,16 endseitig mit einem Leitungssystem für die Trocknerluft-(Thermoluft)Versorgung gekoppelt und erstrecken sich bevorzugt über die maximale Formatbreite. Jedes Rohr 15,16 weist über seine Länge bevorzugt eine Mehrzahl von Ausströmöffnungen 17 auf, die sich gegenüberstehend angeordnet sind (Fig. 2). Alternativ sind die Ausströmöffnungen 17 auch als durchgehende Aussparung in den Hohlkörpern (Rohren) 15, 16 ausführbar.Each
Die Rohre 15,16 sind über die Formatbreite durch eine geschlossene Oberplatte 12 und eine mit Blasöffnungen 14 versehene Unterplatte 13 verbunden, wobei Seitenwände 19 die Ober- und Unterplatte 12,13 endseitig begrenzen. Durch die Ober- und Unterplatte 12,13 sowie die Seitenwände 19 ist somit in Verbindung mit den Hohlkörpern 15, 16 (hier den Rohren 15,16) ein Strömungskanal 20 gebildet.The
Bevorzugt sind die Rohre 15,16 im Außendurchmesser gleich dick ausgeführt, so dass Ober- und Unterplatte 12,13 zueinander parallel angeordnet sind.The
Die Blasöffnungen 14 in der Unterplatte 13 sind als Durchgangsbohrungen und/oder -schlitze ausgeführt und sind bevorzugt in der Unterplatte 13 senkrecht angeordnet, so dass diese annähernd senkrecht auf die Förderebene des Bogenmaterials 8 gerichtet sind. Die Blasöffnungen 14 sind innerhalb der Dicke der Unterplatte 13 angeordnet. Die der Förderebene zugewandte Unterseite der Unterplatte 13 ist somit eine ebene Leitfläche für das Bogenmaterial 8. Die Blasöffnungen 14 sind zueinander bevorzugt mit gleichmäßigen Abstand in der Unterplatte 13 angeordnet.The blowing
Die Ober- und Unterplatten 12,13 und die Seitenwände 19 sind in einer Ausbildung bevorzugt mit den Rohren 15,16 lösbar stoffschlüssig, beispielsweise durch lösbare Klebverbindungen, verbunden. Alternativ sind auch Schraubenverbindungen, einsetzbar.The top and
In einer Weiterbildung sind die Ober- und Unterplatte 12,13 über die Rohre 15,16 hinausgeführt und durch Verbindungselemente 18 miteinander lösbar verbunden (Fig. 2). Die Verbindungselemente 18 dienen zusätzlich der Befestigung der Trocknereinrichtung 9 z.B. an einer Traverse oder an einem sonstigen Haltemittel am Gestell der Auslegers.In a further development, the upper and
In einer weiteren Ausbildung, vorzugsweise für den Schön- und Widerdruckbetrieb mit oder ohne Lackierung des Bogenmaterials 8, ist im Ausleger innerhalb des Fördersystems zwischen dem oberen und unteren Trum zumindest ein Abschottblech angeordnet.
