Abstract

The suction head (18) is placed in the rear region above the paper stack (8) and is mounted to be displaceable respectively in and counter to the paper transport direction for format matching or adjustment. Flexible sheet-guiding elements (26) above a sheet conveying plane have constant length, stationary as well as deflectable by a positional change of suction head. If suction head is displaced in the direction of a crossmember (31), a smaller and constant geometric overall length of the guiding elements is necessary when small format lengths are processed.

Description

Die Erfindung betrifft eine Bogenleiteinrichtung für einen Zuführbereich einer Bogen verarbeitenden Maschine, insbesondere einer Druckmaschine.The invention relates to a sheet guiding device for a feed region of a sheet-processing machine, in particular a printing press.

Bei der Zuführung von Bogen an Bogen verarbeitende Maschinen ist es üblich, eine Saugfördereinrichtung zu verwenden, die Hub- und/oder Schleppsauger umfasst. Die Trennung des obersten Bogens von einem Stapel erfolgt, indem die Hubsauger den Bogen in einer unteren Stellung ansaugen und dann die Hubsauger angehoben werden. Während der Bogen sich in angehobener Stellung befindet, wird von Trennbläsern von der Stapelhinterkante Blasluft unter den Bogen geführt, um die Trennung des Bogens vom Stapel und das Anheben des Bogens zu unterstützen, während zur Erhaltung des Luftdrucks seitliche Lockerungsbläser kontinuierlich Luft gegen die Stapelseitenkanten im vorlaufenden Abschnitt des Bogens blasen. Wenn die Hubsauger ihre höchste Stellung erreicht haben, übernehmen horizontal hin- und hergehende Fördersauger (Schleppsauger) den Bogen von den Hubsaugern, indem sie den Bogen ansaugen und die Saugluft an den Hubsaugern abgestellt wird. Anschließend transportieren die Fördersauger den Bogen durch eine Horizontalbewegung in Richtung der Bogen verarbeitenden Maschine, so dass der vorlaufende Abschnitt des Bogens an einer Übergabestelle an Bogentransporteinrichtungen der nachgeordneten Bogen verarbeitenden Maschine, beispielsweise über einen Anlegetisch geführten Transportbändern, ankommt. Die Übernahme durch die Bogentransporteinrichtung der Bogen verarbeitenden Maschine erfolgt durch getaktetes Absenken von Taktrollen, wodurch der Bogen auf die umlaufenden Transportbänder gedrückt wird. Gleichzeitig mit Absenken der Taktrollen wird die Saugluftzufuhr an die Fördersauger unterbrochen und die Fördersauger in ihre in Bogenförderrichtung hintere Stellung gebracht. Dadurch, dass sich der Bogen auf dem Transportweg von den hinteren Lockerungsbläsern fortbewegt, gelangt zunehmend Luft auf die Oberseite des Bogens, was in einer Flatterbewegung des Bogens resultiert. Dadurch ist der stabile und zuverlässige Transport des abgehobenen Bogens, insbesondere im Bereich des vorlaufenden Bogenbereichs, auf einem vorgegebenen Transportweg an die Bogen verarbeitende Maschine und damit die auf den Maschinentakt der Bogen verarbeitenden Maschine abgestimmte Ankunft des Bogens an der Übergabestelle gefährdet. Zur Lösung dieses Problems werden Bogenleiteinrichtungen oberhalb des Bogenförderweges eingesetzt.When feeding sheets to sheet processing machines, it is common to use a suction conveyor comprising lift and / or drag suckers. The separation of the top sheet from a stack is done by the lifting suckers suck the sheet in a lower position and then the lifting suckers are raised. While the sheet is in the raised position, blower air is fed from the stack trailing edge under the sheet to assist in separating the sheet from the stack and lifting the sheet, while to maintain air pressure, lateral loosening fans continuously draw air against the stack side edges in the leading edge Blow section of the bow. When the lifting suckers have reached their highest position, horizontal reciprocating suckers (drag suckers) take the bow from the lifting suckers by sucking in the bow and stopping the suction air at the lifting suckers. Subsequently, the conveyor suckers transport the sheet by a horizontal movement in the direction of the sheet-processing machine, so that the leading portion of the sheet arrives at a transfer point to sheet transport devices of the downstream sheet processing machine, for example, via a feed table guided conveyor belts. The acquisition by the sheet transport device of the sheet processing machine is done by clocked lowering of clock rollers, whereby the sheet is pressed onto the rotating conveyor belts. Simultaneously with lowering the clock rollers, the suction air supply to the conveyor suction is interrupted and brought the conveyor suckers in their backward in the sheet conveying direction. The fact that the sheet moves on the transport path from the rear loosening fans, air increasingly reaches the top of the sheet, resulting in a fluttering movement of the sheet. As a result, the stable and reliable transport of the lifted sheet, especially in the area of the leading sheet area, on a given transport to the sheet processing machine and thus the on the machine cycle of the bow processing machine endangered arrival of the bow at the transfer point endangered. To solve this problem sheet guiding devices are used above the Bogenförderweges.

Eine derartige Bogenleiteinrichtung ist aus der DE 17 86 232 A1 bekannt. In dem Zuführbereich einer Bogenzuführeinrichtung wird der Bogen auf dem Bogenförderweg über dem Bogenstapel von mehreren horizontal angeordneten, teleskopartig längbaren Bogenleitstangen an seiner Oberseite geführt. Die Teleskopstangen verlaufen von einer in Bogentransportrichtung hinter dem Saugkopf quer zur Bogentransportrichtung angeordnete, mit dem Saugkopf verbundenen Traverse oberhalb des Bogenstapels bis zur Übergabestelle an einen Anlegetisch einer Druckmaschine horizontal in einer Ebene. Bei einer formatabhängigen Verstellung des Saugkopfes in bzw. gegen Bogentransportrichtung werden die o. g. Bogenleitstangen zusammengeschoben. Durch die röhrenförmigen Abschnitte der Bogenleitstangen bilden sich stufenartig verlaufende Abschnitte. Die Leitelemente sind im Wesentlichen formstabil. Ein wesentlicher Nachteil liegt darin, dass die Bogenleitelemente gewartet werden müssen, um ihre Funktionssicherheit zu erhalten, da die Teleskopstangen durch Verschmutzung und Abrieb zunehmendem Verschleiß ausgesetzt sind.Such a sheet guiding device is known from the DE 17 86 232 A1 known. In the feed area of a sheet feeder, the sheet is guided on the sheet conveying path above the stack of sheets by a plurality of horizontally arranged, telescopically elongated Bogenleitstangen at its top. The telescopic rods extend from a in the sheet transport direction behind the suction head arranged transversely to the sheet transport direction, connected to the suction head Traverse above the sheet stack to the transfer point to a feed table of a printing press horizontally in a plane. In a format-dependent adjustment of the suction head in or against the sheet transport direction, the above sheet guide rods are pushed together. Through the tubular sections of the Bogenleitstangen form step-like sections. The guide elements are essentially dimensionally stable. A major disadvantage is that the sheet guiding elements must be maintained in order to maintain their functional reliability, since the telescopic rods are exposed to increasing wear due to contamination and abrasion.

Durch die DE 195 37 284 C1 ist es bekannt, elastische bzw. dehnbare Leitbänder einzusetzen, die entsprechend dem Verfahrweg des Saugkopfes eine Längendehnung erfahren bzw. mittels vorgesehener Spulelemente abgewickelt werden.By the DE 195 37 284 C1 It is known to use elastic or stretchable Leitbänder, which experience according to the travel of the suction head elongation or unwound by means provided spooling.

Der Erfindung liegt die Aufgabe zugrunde, eine alternative Bogenleiteinrichtung zu schaffen, die Bogen im Zuführbereich von Bogen verarbeitenden Maschinen, insbesondere Druckmaschinen, sicher und beschädigungsfrei führt und sowohl auf Bogenlängsformat als auch Bogenquerformat verstellbar ist.The invention has for its object to provide an alternative sheet guiding device, the sheet in the feed of sheet-processing machines, especially printing machines, safely and without damage leads and is adjustable both to sheet length format and sheet cross format.

Die Lösung dieser Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The solution to this problem is solved by the features of claim 1.

Ein Vorteil der Erfindung besteht darin, dass die Bogenleitelemente nicht nur in Bogenlängsrichtung, sondern auch in Bogenquerrichtung auf Format verstellt werden können, so dass die seitliche Formatverstellung von Einrichtungen, z. B. seitlichen Stapelanschlägen oder seitlichen Lockerungsbläsern, nicht durch die Bogenleiteinrichtung behindert wird und dennoch eine Bogenführung über die gesamte Bogenbreite erfolgt.An advantage of the invention is that the sheet guiding elements are adjusted to format not only in the sheet longitudinal direction, but also in the sheet transverse direction can, so that the lateral format adjustment of facilities, such. B. lateral stack stops or lateral loosening blowers, is not hindered by the sheet guide and yet a bowing over the entire sheet width.

Ein weiterer Vorteil der Erfindung besteht darin, dass stufenlose Leiteinrichtungen mit geringer Reibung geschaffen werden.Another advantage of the invention is that infinitely variable, low friction vanes are provided.

Zudem bieten die erfindungsgemäßen Bogenleitelemente den Vorteil, dass sie äußerst wartungsarm sind, da wegen stumpfer Umlenkwinkel für das Bandmaterial starkes Seilmaterial verwendet werden kann, welches entsprechend verschleißarm ist. Formatdifferenzen vom Größt- zum Kleinstformat in Papierlängenrichtung brauchen an den Leitschnüren nicht ausgeglichen werden, da diese am Saugkopf keinen Fixpunkt haben, sondern nur umgelenkt werden.In addition, the sheet guiding elements according to the invention have the advantage that they are extremely low maintenance, since due to blunt deflection for the strip material strong rope material can be used, which is correspondingly low wear. Format differences from the largest to the smallest format in the paper length direction need not be compensated at the guide cords, as they have no fixed point on the suction head, but only deflected.

Die Bogen 7 werden von einem Bogenstapel 8 entnommen und vereinzelt oder schuppenförmig über einen Zuführtisch 9 einer Bogenzuführvorrichtung 27 zugeführt, die die Bogen 7 beschleunigt an die Druckwerke 3 und 4 übergibt. Diese enthalten in bekannter Weise jeweils einen Plattenzylinder 11, 12. Die Plattenzylinder 11 und 12 weisen jeweils eine Vorrichtung 13, 14 zum Befestigen flexibler Druckplatten auf. Darüber hinaus ist jedem Plattenzylinder 11, 12 eine Vorrichtung 16, 17 für den halb- oder vollautomatischern Druckplattenwechsel zugeordnet.A sheet 7 processing machine, z. As a printing press 1, has a feeder 2, at least one printing unit 3 or 4 and a boom 6 on. The sheet 7 are removed from a sheet pile 8 and isolated or flaky over a Feeding table 9 fed to a sheet feeding device 27, which accelerates the sheet 7 passes to the printing units 3 and 4. These contain in a known manner in each case a plate cylinder 11, 12. The plate cylinder 11 and 12 each have a device 13, 14 for attaching flexible printing plates. In addition, each plate cylinder 11, 12 is associated with a device 16, 17 for the semi-automatic or fully automatic printing plate change.

Der Bogenstapel 8 liegt auf einer gesteuert anhebbaren Stapelplatte 10 auf. Die Entnahme der Bogen 7 erfolgt von der Oberseite des Bogenstapels 8 mittels eines so genannten Saugkopfes 18, der unter anderem eine Anzahl von Hub- und Schleppsaugern 19, 21 für die Vereinzelung der Bogen 7 aufweist. Darüber hinaus sind Blaseinrichtungen 22 zur Auflockerung der oberen Bogenlagen und Tastelemente 23 zur Stapelnachführung vorgesehen. Zur Ausrichtung des Bogenstapels 8, insbesondere der oberen Bogen 7 des Bogenstapels 8 sind eine Anzahl von seitlichen und hinteren Anschlägen 24 vorgesehen.The sheet stack 8 rests on a controllably liftable stacking plate 10. The removal of the sheet 7 takes place from the top of the sheet stack 8 by means of a so-called suction head 18, which, inter alia, a number of lifting and Schleppsaugern 19, 21 for the separation of the sheet 7 has. In addition, blowing devices 22 are provided for loosening the upper sheet layers and sensing elements 23 for stack tracking. For aligning the sheet stack 8, in particular the upper sheet 7 of the sheet pile 8, a number of lateral and rear stops 24 are provided.

Der Saugkopf 18 ist im hinteren Bereich oberhalb des Bogenstapels 8 angeordnet und in bzw. gegen die Bogentransportrichtung zur Formatanpassung verschiebbar gelagert. Auf einem gemeinsamen Höhenniveau zwischen Saugkopf 18 und Bogenstapeloberseite sind eine Anzahl von flexiblen Bogenleitelementen 26, z. B. in Form von Seilen, Schnüren, Bändern, etc. vorgesehen, die dafür sorgen, dass ein von den Blaseinrichtungen 22 mit Blasluft beaufschlagter Bogen nicht nach oben die vorgesehene Transportstrecke verlassen kann. Die Bogenleitelemente 26 sind mit ihrem ersten Ende 27 an einer ersten Quertraverse 28 befestigt, die in Bogentransportrichtung vor dem Bogenstapel 8 angeordnet ist, und mit ihrem zweiten Ende 29 an einer zweiten Quertraverse 31 befestigt, welche dem Bogenstapel 8 nachgeordnet ist.The suction head 18 is arranged in the rear region above the sheet stack 8 and slidably mounted in or against the sheet transport direction for format adaptation. At a common height level between suction head 18 and sheet pile top are a number of flexible sheet guiding elements 26, z. B. in the form of ropes, cords, belts, etc., which ensure that one of the blowing devices 22 acted upon with blowing air sheet can not leave the intended transport route upwards. The sheet guiding elements 26 are fastened with their first end 27 to a first cross-beam 28, which is arranged in the sheet transport direction in front of the sheet stack 8, and fixed with its second end 29 to a second cross-beam 31, which is arranged downstream of the sheet stack 8.

Jeweils eine an der hinteren Quertraverse 28 angeordnete federbelastete Spannrolle 32 wird von je einem Bogenleitelement 26 teilumschlungen. Zwei Umlenkrollen 33, 34 je Bogenleitelement 26 sind an Hebeln 35, 40 befestigt und derart nach unten gerichtet am Saugkopf 18 angeordnet, dass die Bogenleitelemente 26 unterhalb und seitlich um den Saugkopf 18 herum geführt werden. Das zweite Ende 29 jedes Bogenleitelementes 26 ist mittels einer höhenverstellbaren und axial verschiebbaren Halterung 36 an der zweiten Traverse 31 angeordnet. Die Halterung 36 und die Umlenkrollen 33, 34 werden in ihrer Höhe vorzugsweise so angeordnet, dass die Bogenleitelemente 26 in etwa in einer gemeinsamen Leitebene E in etwa parallel zur Oberseite des Bogenstapels 8 bzw. einer Förderebene liegen.In each case arranged on the rear cross-beam 28 spring-loaded tensioning roller 32 is partially entwined by a respective sheet guide 26. Two pulleys 33, 34 each sheet guide 26 are attached to levers 35, 40 and arranged directed downwards on the suction head 18, that the sheet guiding elements 26 are guided below and laterally around the suction head 18 around. The second end 29 of each sheet guiding element 26 is connected to the second by means of a height-adjustable and axially displaceable holder 36 Traverse 31 arranged. The holder 36 and the guide rollers 33, 34 are preferably arranged in height so that the sheet guide elements 26 are approximately parallel to the top of the sheet stack 8 and a conveying plane in approximately a common control plane E.

Wird bei der Verarbeitung kleiner Formatlängen der Saugkopf 18 in Bogentransportrichtung, d. h. in Richtung der zweiten Traverse 31 verschoben, so ist eine kleinere geometrische Baulänge der konstant langen Bogenleitelemente 26 notwendig. Damit die Bogenleitelemente 26 jedoch konstant gespannt gehalten werden können, wird von der Spannrolle 32 eine kleine Auslenkung der Bogenleitelemente 26 bewirkt.When the processing of small format lengths of the suction head 18 in the sheet transport direction, d. H. shifted in the direction of the second traverse 31, so a smaller geometric length of the constant length sheet guide elements 26 is necessary. However, so that the sheet guiding elements 26 can be kept constantly taut, a small deflection of the sheet guiding elements 26 is effected by the tensioning roller 32.

Bei einer zweiten Ausführungsform gemäß Figur 4 ist es vorgesehen, dass die erste Umlenkrolle 33 durch eine Kombination von zwei s-förmig umschlungenen Umlenkrollen 41, 42 ersetzt wird, wobei eine Umlenkrolle 42 an einem federbelasteten Hebel 43 angeordnet ist, während die andere Umlenkrolle 41 stationär am Saugkopf 18 angeordnet ist. Durch diese Führung der Bogenleitelemente 26 muss ein Verfahrweg des Saugkopfes 18 nicht ausgeglichen werden.In a second embodiment according to FIG. 4, it is provided that the first deflecting roller 33 is replaced by a combination of two deflecting rollers 41, 42 looped in an S-shape, one deflecting roller 42 being arranged on a spring-loaded lever 43, while the other deflecting roller 41 is stationary is arranged on the suction head 18. Due to this guidance of the sheet guiding elements 26, a travel path of the suction head 18 need not be compensated.

Der Saugkopf 18 ist im hinteren Bereich oberhalb des Bogenstapels 8 angeordnet und in bzw. gegen die Bogentransportrichtung zur Formatanpassung verschiebbar gelagert. Auf einem Höhenniveau zwischen Saugkopf 18 und Bogenstapeloberseite sind eine Anzahl von flexiblen Bogenleitelementen 26, z. B. in Form von Seilen, Schnüren, Bändern, etc., vorgesehen, die dafür sorgen, dass ein von den Blaseinrichtungen beaufschlagter Bogen 7 nicht nach oben die vorgesehene Transportstrecke verlassen kann. Die Bogenleitelemente 26 sind mit ihrem ersten Ende 27 an einer ersten Quertraverse 28 befestigt, die in Bogentransportrichtung vor dem Bogenstapel 8 angeordnet ist, und mit ihrem zweiten Ende 29 an einer zweiten Quertraverse 31, welche dem Bogenstapel 8 nachgeordnet ist.The suction head 18 is arranged in the rear region above the sheet stack 8 and slidably mounted in or against the sheet transport direction for format adaptation. At a height level between suction head 18 and sheet pile top are a number of flexible sheet guide elements 26, z. As in the form of ropes, cords, ribbons, etc., provided that ensure that an acted upon by the blowing devices sheet 7 can not leave the intended transport route upwards. The sheet guiding elements 26 are fastened with their first end 27 to a first cross-beam 28, which is arranged in the sheet transport direction in front of the sheet stack 8, and with its second end 29 on a second cross-beam 31, which is arranged downstream of the sheet stack 8.
