Every guide element has obliquely arranged in the wall, against the pressure cylinder and the direction of conveyance of the printing material directed blowing air openings, which prevent the sheet from lifting off the impression cylinder surface.
- the interior of the hollow cylindrical guide element represents the blown air chamber which is coupled with a pneumatic system for the blower supply.
- the Blowing air openings wall of the guide elements provides a Outer contour, which is adapted to the outer surface of the printing cylinder. Farther additional blown air openings are arranged, which - transversely to the direction of movement considered - in the edge area of the guide elements inwards and outwards are directed outside.
- a sheetfed press for perfecting on the principle Rubber against rubber in a pressure zone is known from DE 26 03 483 A1.
- the sheet guide is designed such that in the conveying direction of the printing material a first blow pipe with openings coupled to a compressor is arranged, the blown air jet of the printing material against the feed drum presses and a contact of the substrate with the lower blanket cylinder prevented in front of the pressure nip.
- a Suction box arranged with a preferably concave curved suction surface, which serves to suck in the printing material.

- the sheet guiding device is with several pneumatic systems coupled and has openings for placing the printing material on the The outside surface of the sheet guide cylinder is blown on. This facility exists from several chambers that are not functionally interconnected with openings for the blowing air outlet and forms with the sheet guide cylinder an inlet gap that tapers in the conveying direction to the pressure gap.
- the invention has for its object a sheet guiding device in a To create printing machine that avoids the disadvantages mentioned, in particular a more even guidance of the substrate without touching the Permitted sheet guiding device on the impression cylinder and an improved Guaranteed entry of the substrate into a printing nip.
- the sheet guiding device To lift the sheet-like substrate from the impression cylinder surface different pressure ratios on the The top of the substrate. So is in the conveying direction of the substrate that formed from blanket cylinder (or forme cylinder) and impression cylinder Arranged a sheet guiding device in which the kinetic Energy of the blown air flow is converted into printing energy acting on the printing material is. The printing energy acting on the substrate is in the conveying direction increasing towards the pressure gap.
- the sheet guiding device has several pneumatically actuated chambers on the substrate have directed openings for the blowing air outlet.
- the sheet guiding device is arranged in front of the printing nip in such a way that between the underside of the sheet guiding device and the impression cylinder surface an inlet gap is formed, which in the conveying direction to the pressure gap has a tapered course.
- sheet guiding device in addition to that in front of the pressure gap in the conveying direction arranged sheet guiding device a further sheet guiding device arranged after the printing nip.
- This sheet guide device is used for guidance the substrate when leaving the printing nip. It is on the Printing energy acting on the printing material falling in the conveying direction after the printing nip, the sheet guiding device having a plurality of pneumatically actuatable has openings for the blowing air outlet directed towards the printing material. Between the underside of the sheet guiding device and the surface of the impression cylinder an outlet gap is formed, starting from the pressure gap in the conveying direction has an enlarged gap.
- a sheet-fed rotary printing press is shown in a row construction in accordance with FIG. 1.
- Several printing units 1 with printing cylinders 10 are strung together and connected to each other by means of transfer drums 4 or turning systems 3.
- Transfer drums 4 and turning systems 3 have associated sheet guiding devices 7 on.
- the last printing unit 1 is followed by a delivery 2, which the printing material by means of sprocket shaft 5 and revolving chain system 6 transported in the conveying direction 8 along sheet guiding devices 7 and on a boom stack.
- Each printing unit 1 consists of in a known manner a printing cylinder 10, a blanket cylinder 11 and a plate cylinder 24.
- the plate cylinder 24 is an inking unit and possibly a dampening unit assigned, so that we shall not go into further here.
- one or more coating units can also be assigned to the printing units.
- a coating unit is comparable to a printing unit 1.
- the blanket cylinder 11 of the printing unit then, as is known, corresponds to the forme cylinder of the coating unit, which with an application roller and a coating system in Functional connection is.
- the printing cylinder 10 also takes over in the coating unit Function of the sheet guide cylinder.
- Blanket cylinder 11 (or forme cylinder) and impression cylinder 10 form one Printing nip 12, through which in the printing on position the sheet-shaped printing material transported and printed or varnished.
- the printing material lying on the outer surface of the printing cylinder 10 contactless to the blanket cylinder (forme cylinder) 11 the printing nip 12 happen.
- a sheet guiding device 9 is arranged in the conveying direction 8 in front of the printing gap 12.
- the sheet guiding device 9 has an approximately wedge-shaped cross section, which extends in a box shape over the width of the impression cylinder or at least over the minimum width of the format and is coupled to a pneumatic system for the supply of blown air.
- the sheet guiding device 9 projects into the gusset-shaped space of the printing nip 12, formed by blanket cylinders (forme cylinders) 11 and printing cylinders 10, and is divided into several chambers by partitions - in the present embodiment into three chambers 13, 14, 15.
- the chambers 13 to 15 have openings 16, the blowing air emerging therefrom having a gradient with respect to the pressure energy P 1 to P 3 , such that the pressure energy P 1 of the blowing air is greatest at the openings 16 of the chamber 13 and the pressure energy P 3 of the blowing air at the openings 16 of the chamber 15 is lower.
- the sheet guiding device 9 is supported on both sides in side frames.
- the bearing is preferably a swivel 25, so that the sheet guiding device 9 can be pivoted at a defined angle about the axis of rotation.
- the sheet guide device 9 can thus be adjusted in its distance from the printing cylinder 10, for example depending on the weight per unit area of the printing materials to be processed or on the printing subject. This distance represents an inlet gap 23 which - despite the pivotability of the sheet guiding device 9 - is always tapered in the direction of the printing gap 12.
- Each chamber 13 to 15 can have a separate blown air supply 17. Since there is often limited space in the gusset-shaped pressure gap 12, preferably only one blown air supply 17 is coupled to the chamber 15 remote from the pressure gap 12 (see FIG. 3). Air ducts 19 with corresponding openings 20 protrude from this chamber 15 like a comb into the chamber 13 adjacent to the pressure gap 12. The blown air supply 17 has openings 18 which are functionally connected to the air supply 19. The partitions between the chambers 13, 14 and 14, 15 in turn have openings 21, 22. The air flows through the openings 21 from the chamber 13 to the chamber 14 and back through the openings 22 from the chamber 14 to the chamber 15.
- blowing air flows out of the openings 16 arranged on the underside of the sheet guiding device 9, the kinetic energy being converted into printing energy P 1 to P 3 acting on the printing material.
- the pressure energy P 1 is assigned to the area of the chamber 13, the pressure energy P 2 to the area of the chamber 14 and the pressure energy P 3 to the area of the chamber 15, where P 1 > P 2 > P 3 applies.
- the openings 16 in the sheet guiding device 9 are arranged obliquely, so that the blown air flow is directed against the conveying direction 8 of the printing material guided on the printing cylinder 10 in order to prevent the printing material from being lifted off, in particular the trailing edge, from the outer surface of the printing cylinder 10 .
- the sheet guiding device 9 has at least one further opening 16 which - in the direction of the printing gap 12 - is directed against the blanket cylinder (forme cylinder) 11 in such a way that the blown air flow in front of the printing gap 12 blows against the blanket cylinder (forme cylinder) 11 and on the blanket cylinder (Forme cylinder) 11 deflected and directed against the conveying direction 8, the printing material on the jacket of the printing cylinder 10 guides and smoothes out.
- a further sheet guiding device 9 for guiding the printing material after the printing nip 12 is arranged in a second embodiment.
- the downstream sheet guiding device 9 is essentially a mirror image of the sheet guiding device 9 arranged upstream of the printing nip 12.
- the training is not limited to three chambers 13 to 15.
- the sheet guide device 9 with only one chamber 13 or gem.
- Fig. 2 formed with two chambers 13, 14, which extend at least over the minimum format width, but preferably over the cylinder width.
- the downstream sheet guiding device 9 has a blown air supply (not shown) in the chamber 14, which is designed analogously to the blown air supply 17 with air supply 19 and openings 20 of the upstream sheet guiding device 9.
- a partition with openings 21 is again arranged between the chambers 13, 14.
- the chambers 13, 14 On the underside of the sheet guiding device 9, the chambers 13, 14 have openings 16 for the blowing air outlet.
- the kinetic energy of the exiting blown air is in turn converted into printing energy P 1 , P 2 acting on the printing material.
- the chamber 13 is adjacent to the pressure gap 12 and the chamber 14 faces away from the pressure gap.
- the chamber 13 is associated with pressure energy P 1 is greater than that of the chamber 14 associated Drukk energie P 2 (P 1> P 2).
- the openings 16 in the sheet guiding device 9 are arranged obliquely, so that the blown air flow is directed against the conveying direction 8 of the printing material guided on the printing cylinder 10 in the direction of the printing nip 12, so that the printing material is also lifted off the printing cylinder 12 when it leaves the printing nip 12 10 to avoid.
- the downstream sheet guiding device 9 preferably has at least one further opening 16, which is directed in the direction of the printing gap 12 and blows a blown air flow against the blanket cylinder (forme cylinder) 11 and / or tangential to the blanket cylinder (forme cylinder) 11 in the direction of the printing gap 12.
- the sheet guiding device 9 is in turn preferably pivotally mounted in swivel joints fixed to the frame, so that the distance from the printing cylinder 10 is adjustable. This distance represents an outlet gap 26 which, starting from the pressure gap 12, widens in the conveying direction 8, regardless of the pivotability of the sheet guiding device 9.
- the mode of operation is as follows: In the printing on position (blanket cylinder / forme cylinder 11 is in pressure contact with printing cylinder 10), the sheet-like printing material is transferred from the transfer drum 4 or the turning system 3 to the printing cylinder 10 and transported there in the gripper closure in the conveying direction 8.
- the sheet guiding device 9 arranged upstream of the printing nip 12 generates a constant blown air flow at the openings 16, the kinetic energy being converted into printing energy P 1 to P 3 acting on the printing material.
- the lower printing energy P 3 initially acts on the printing material, then the higher printing energy P 2 and finally the highest printing energy P 1 .
- the printing energy P 1 which results from the blown air flow directed towards the blanket cylinder / forme cylinder 11 (opening 16 in the tip of the chamber 13), is deflected on the outer surface of the blanket cylinder / forme cylinder 11 and spreads out the printing material against the conveying direction 8.
- the print-off position bladenket cylinder / forme cylinder 11 is out of contact with the impression cylinder 10
- the blown air flow is maintained.
- the printing cylinder 10 continues to guide the printing material past the activated sheet guiding device 9 in the conveying direction 8 in the gripper closure and the printing energies P 3 ⁇ P 2 ⁇ P 1 act on the upper side of the printing material.
- the printing energy P 1 which also results from the blowing air flow directed towards the blanket cylinder / forme cylinder 11 (opening 16 in the tip of the chamber 13), is deflected at the blanket cylinder / forme cylinder 11 and spreads out the printing material counter to the conveying direction 8.
- the printing energies P 1 > P 2 act on the printing material in the conveying direction 8.
- the pressure energy P 1 which results from the blowing air flow directed towards the blanket cylinder / forme cylinder 11 or the pressure gap 12 (opening 16 in the top of the chamber 13), is reduced in the pressure on position on the jacket of the blanket cylinder / forme cylinder 11.
- the blown air emerging from the openings 16 in the tip of the respective chamber 13 flows from the sheet guide 9 downstream of the printing gap 12 with the sheet guide 9 from the opposite upstream in the direction of the blanket cylinder / forme cylinder 11 and into the exposed printing gap 12, and forms on the jacket of the rubber blanket cylinder / forme cylinder 11, an air cushion resulting from the printing energy P 1 , which prevents contact of the conveyed printing material with the blanket cylinder / forme cylinder 11.

- eine Bogenrotationsdruckmaschine
- Fig. 2
- eine Bogenführungseinrichtung im Bereich des Druckspaltes
- Fig. 3
- die Bogenführungseinrichtung vor dem Druckspalt im Schnitt
Gleichzeitig strömt aus den an der Unterseite der Bogenführungseinrichtung 9 angeordneten Öffnungen 16 Blasluft aus, wobei die kinetische Energie in auf den Bedruckstoff wirkende Druckenergie P1 bis P3 umgesetzt ist. Dabei ist die Druckenergie P1 dem Bereich der Kammer 13, die Druckenergie P2 dem Bereich der Kammer 14 und die Druckenergie P3 dem Bereich der Kammer 15 zugeordnet, wobei P1 > P2 > P3 gilt.
Darüber hinaus weist die Bogenführungseinrichtung 9 wenigstens eine weitere Öffnung 16 auf, welche - in Richtung Druckspalt 12 - gegen den Gummituchzylinder (Formzylinder) 11 gerichtet ist, derart, daß die Blasluftströmung vor dem Druckspalt 12 gegen den Gummituchzylinder (Formzylinder) 11 bläst und am Gummituchzylinder (Formzylinder) 11 abgelenkt und gegen die Förderrichtung 8 gerichtet den Bedruckstoff auf dem Mantel des Druckzylinders 10 glatt führt und ausstreicht.
In bevorzugter Ausbildung sind die Öffnungen 16 in der Bogenführungseinrichtung 9 schräg angeordnet, so daß die Blasluftströmung gegen die Förderrichtung 8 des auf dem Druckzylinder 10 geführten Bedruckstoffes in Richtung Druckspalt 12 gerichtet ist, um auch beim-Verlassen des Druckspaltes 12 ein Abheben des Bedruckstoffes vom Druckzylinder 10 zu vermeiden.
Darüber hinaus weist bevorzugt die nachgeordnete Bogenführungseinrichtung 9 wenigstens eine weitere Öffnung 16 auf, welche in Richtung Druckspalt 12 gerichtet ist und eine Blasluftströmung gegen den Gummituchzylinder (Formzylinder) 11 und/oder tangential zum Gummituchzylinder (Formzylinder) 11 in Richtung Druckspalt 12 bläst. Die Bogenführungseinrichtung 9 ist wiederum bevorzugt in gestellfesten Drehgelenken schwenkbar gelagert, so daß der Abstand zum Druckzylinder 10 einstellbar ist. Dieser Abstand stellt einen Auslaufspalt 26 dar, der sich vom Druckspalt 12 ausgehend -unabhängig von der Schwenkbarkeit der Bogenführungseinrichtung 9 - in Förderrichtung 8 erweitert.
In Druck ab-Stellung (Gummituchzylinder / Formzylinder 11 ist mit dem Druckzylinder 10 außer Kontakt), d.h. es ist ein Freiraum zwischen Gummituchzylinder / Formzylinder 11 und Druckzylinder 10 von wenigstens 2 mm, wird die Blasluftströmung aufrechterhalten. Der Druckzylinder 10 führt weiterhin im Greiferschluß den Bedruckstoff an der aktivierten Bogenführungseinrichtung 9 in Förderrichtung 8 vorbei und die Druckenergien P3 < P2 < P1 wirken auf die Oberseite des Bedruckstoffes. Die Druckenergie P1, welche auch aus der auf den Gummituchzylinder / Formzylinder 11 gerichteten Blasluftströmung resultiert (Öffnung 16 in der Spitze der Kammer 13), wird am Gummituchzylinder / Formzylinder 11 abgelenkt und streicht den Bedruckstoff entgegen der Förderrichtung 8 aus.
In Druck ab-Stellung strömt die aus den Öffnungen 16 in der Spitze der jeweiligen Kammer 13 austretende Blasluft der dem Druckspalt 12 nachgeordneten Bogenführung 9 mit der aus der gegenüberliegend vorgeordneten Bogenführung 9 in Richtung Gummituchzylinder/Formzylinder 11 und in den freiliegenden Druckspalt 12, und bildet am Mantel von Gummmituchzylinder/Formzylinder 11 ein Luftpolster, resultierend aus der Druckenergie P1, aus, welches den Kontakt des geförderten Bedruckstoffes mit dem Gummituchzylinder/Formzylinder 11 verhindert.
