Abstract

To increase the efficiency of sheet printing machines, the printed sheet leaving the sheet printing machine is passed through, in direct connection with the printing machine, between folding cylinders (2-5) having interacting folding knives (7, 9, 11), which can be displaced over the cylinder circumference, and folding flaps (8, 10, 12), and in this arrangement the printed sheet is transversely folded one or more times, whereupon the transversely folded printed sheet is cut transversely with respect to its running direction at its rear transverse edge and then divided by longitudinal blades into individual, adjacent printing products, which are then stacked. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von gefalzten Druckprodukten.The invention relates to a method and an apparatus for producing folded printed products.

Beim Rollenrotationsdruck, welcher den Vorteil hoher Druckgeschwindigkeit aufweist, ist der Druckmaschine eine Falzvorrichtung nachgeschaltet, die eine hohe Wirtschaftlichkeit gewährleistet, weil das Produkt die Anlage versandfertig verlassen kann. Bogendruckmaschinen, die den Druckträger meist nur einseitig bedrucken, haben gegenüber Rollendruckmaschinen, mit Ausnahme des Tiefdruckverfahrens, den Vorteil der Formatungebundenheit, anderseits den Nachteil, daß die Druckprodukte nach dem letzten Durchgang zwischengestapelt und sodann in gesonderten Arbeitsvorgängen mit Hilfe von separaten Falzvorrichtungen gefalzt werden, was mit einem großen Zeit- und Manipulationsaufwand verbunden ist.In the case of web-fed rotary printing, which has the advantage of high printing speed, the printing machine is followed by a folding device which ensures high economic efficiency because the product can leave the system ready for dispatch. Sheet printing machines, which usually only print on one side of the printing medium, have the advantage over format printing machines, with the exception of the gravure printing process, that they are not tied to the format, on the other hand the disadvantage that the printed products are stacked after the last pass and then folded in separate work processes with the help of separate folding devices, which is associated with a great deal of time and manipulation.

Die Erfindung zielt nun darauf ab, ein Verfahren und eine Vorrichtung zum Herstellen von gefalzten Druckprodukten zur Anwendung bei Bogendruckmaschinen, insbesondere bei im Schön- und Widerdruckverfahren arbeitenden Bogendruckmaschinen, zu schaffen, die eine hohe Wirtschaftlichkeit der Druckmaschine sichern, indem sie die Abgabe von versandfertigen Druckprodukten ermöglichen.The invention now aims to provide a method and an apparatus for producing folded printed products for use in sheet-fed printing presses, in particular in sheet-fed and reverse printing sheet-fed printing presses, which ensure high cost-effectiveness of the printing press by dispensing ready-to-ship printed products enable.

Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, daß der eine Bogendruckmaschine verlassende Druckbogen im unmittelbaren Anschluß an die Druckmaschine zwischen Falzzylindern mit zusammenwirkenden, über den Zylinderumfang verstellbaren Falzmessern und Falzklappen hindurchgeführt und dabei ein oder mehrmals quergefalzt wird, worauf der quergefalzte Druckbogen quer zu seiner Laufrichtung an seinem hinteren Querrand geschnitten und sodann durch Längsschneiden in einzelne nebeneinanderliegende Druckprodukte unterteilt wird, die anschließend gegebenenfalls gestapelt werden.The method according to the invention is characterized in that the printing sheet leaving a sheet-fed printing press is guided in the direct connection to the printing machine between folding cylinders with cooperating folding knives and folding flaps which can be adjusted over the cylinder circumference, and is then folded one or more times, whereupon the cross-folded printed sheet transversely to its direction of travel cut its rear transverse edge and then by cutting longitudinally into individual side by side lying printed products is divided, which may then be stacked.

Eine zur Durchführung dieses Verfahrens bestimmte Vorrichtung, die mit Falzzylindern ausgestattet ist, hat gemäß der Erfindung die Merkmale, daß zum unmittelbaren Anschluß an eine Bogendruckmaschine ein Übernahmezylinder mit Greifern vorgesehen ist, der mit einem gegenüber den Greifern in Zylinderumfangsrichtung stufenlos verstellbaren Falzmesser ausgestattet ist und dem mehrere Falzzylinder nachgeschaltet sind, die ihrerseits je eine Falzklappe und je ein Falzmesser aufweisen, welche in Zylinderumfangsrichtung stufenlos verstellbar sind, daß den Falzzylindern eine mit einer verstellbaren Anlage ausgerüstete Schneideinrichtung zum Schneiden des gefalzten Druckbogens in der Querrichtung und im Anschluß an diese Schneideinrichtung zumindest eine quer zur Laufrichtung verstellbare Schneideinrichtung zum Unterteilen des gefalzten Druckbogens in einzelne nebeneinanderliegende Druckprodukte sowie gegebenenfalls ein Stapler zum Sammeln und zum Abtransport dieser Druckprodukte nachgeschaltet sind.A device intended for carrying out this method, which is equipped with folding cylinders, has the features according to the invention that a takeover cylinder with grippers is provided for direct connection to a sheet-fed printing press, which is equipped with a folding knife which is infinitely adjustable in relation to the grippers in the cylinder circumferential direction, and that several folding cylinders are connected, each of which has a folding flap and a folding knife, which are continuously adjustable in the cylinder circumferential direction, that the folding cylinders have a cutting device equipped with an adjustable system for cutting the folded printing sheet in the transverse direction and following this cutting device, at least one crosswise cutting device adjustable to the running direction for dividing the folded printed sheet into individual print products lying next to one another and, if appropriate, a forklift downstream for collecting and transporting these printed products s ind.

Diese Ausbildung gewährleistet eine rationelle und kostensparende Behandlung der Druckprodukte nach dem Druckvorgang in Bogendruckmaschinen, die keinen endlosen Druckträger, sondern verschiedenformatige Bogen bedrucken, weil die Druckprodukte die Anlage versandfertig, d.h. im gezählten und gestapelten Zustand verlassen und das bisher erforderliche Zwischenstapeln sowie daran anschließende gesonderte Falz- und Schneidevorgänge entfallen. Die Erfindung eignet sich besonders für Mehrfarben-Schön- und Widerdruckbogenmaschinen, wie sie in der europäischen Patentanmeldung 82890154.6 vom 25. Oktober 1982 beschrieben sind.This training ensures a rational and cost-saving treatment of the printed products after the printing process in sheet-fed printing machines which do not print on endless print carriers but on different-sized sheets, because the printed products are ready for dispatch, i.e. leave in the counted and stacked state and the previously required intermediate stacking and subsequent separate folding and cutting processes are no longer necessary. The invention is particularly suitable for multi-color perfecting and offset printing presses, as described in European patent application 82890154.6 dated October 25, 1982.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigen

  • Figur 1 eine schematische Seitenansicht einer Vorrichtung gemäß der Erfindung,
  • Figur 2 eine Draufsicht auf einen Teil der Vorrichtung nach Figur 1 und die
  • Figuren 3a und 3b schematische Seitenansichten zweier gemäß der Erfindung gefalzter Druckprodukte.
The invention is explained in more detail below using an exemplary embodiment with reference to the drawing explained. Show it
  • FIG. 1 shows a schematic side view of a device according to the invention,
  • Figure 2 is a plan view of part of the device of Figure 1 and the
  • Figures 3a and 3b are schematic side views of two printed products folded according to the invention.

Die dargestellte Vorrichtung ist besonders für Schön- und Widerdruckbogenmaschinen mit Ein- und Mehrfarbendruck geeignet. Der Druckbogen B wird von einer Auslegetrommel 1 an einen im direkten Greiferschluß im Verhältnis 1 : 1 mitgetriebenen und umfangsgleichen Übernahmezylinder 2 abgegeben. Am Übernahmezylinder 2 ist ein Falzmesser 7 vorgesehen, das in Zylinderumfangsrichtung relativ zu Greifern 6 stufenlos verstellbar ist, wie dies durch die strichlierten Pfeile angedeutet ist. Dem Übernahmezylinder 2 ist ein ebenfalls im Verhältnis 1 : 1 mitgetriebener Falzklappen- und Falzmesserzylinder 3 so nachgeordnet, daß der Druckbogen B im äußersten Fall sogar über seine halbe Länge von dem Falzmesser 7 in eine am Zylinder 3 angeordnete, in Zylinderumfangsrichtung stufenlos verstellbare Falzklappe 8 gedrückt werden kann, damit die Greifer 6 rechtzeitig für die Übernahme des nachfolgenden Druckbogens frei sind. Auf diese Weise wird im Druckbogen B ein erster Querfalz ausgebildet.The device shown is particularly suitable for single-sheet and multi-color printing. The printed sheet B is delivered from a delivery drum 1 to a takeover cylinder 2 which is driven in the direct gripper closure in a ratio of 1: 1 and has the same circumference. A folding knife 7 is provided on the take-over cylinder 2 and is infinitely adjustable in the cylinder circumferential direction relative to grippers 6, as is indicated by the dashed arrows. The takeover cylinder 2 is also a 1: 1 driven folding jaw and folding knife cylinder 3 so that the sheet B is pressed in the extreme case even over half its length from the folding knife 7 into a cylinder 3 arranged, continuously adjustable in the cylinder circumferential folding flap 8 can be so that the grippers 6 are free in time for the takeover of the subsequent sheet. In this way, a first transverse fold is formed in the printed sheet B.

Der Zylinder 3, der mit einem über den Zylinderumfang stufenlos verstellbaren Falzmesser 9 versehen ist, führt den von der Falzklappe 8 gefalteten und gehaltenen Druckbogen B in Umfangsrichtung über jene Stelle hinaus, an welcher der Umfang des Zylinders 3 einem nachgeschalteten mitlaufenden Zylinder 4 am nächsten liegt. Das verstellbare Falzmesser 9 drückt dann an dieser Stelle, an der zum zweiten Mal quergefalzt werden soll, den Druckbogen B in eine verstellbare Falzklappe 10 des Zylinders 4. Der Zylinder 4 hat nach Öffnen der Falzklappe 8 den nun zweimal gefalzten Bogen B übernommen und führt den von der Falzklappe 10 gehaltenen Bogen einem weiteren mitlaufenden Zylinder 5 zu. Ein Falzmesser 11 des Zylinders 4 drückt an der Stelle, an welcher zum dritten Mal quergefalzt werden soll, den Bogen 13 in eine Falzklappe 12 des Zylinders 5. Der vorstehend erläuterte Falzvorgang kann so oft wiederholt werden, als zusammenwirkende Falzklappen- und Falzmesserzylinder 5a, 5b usw. vorhanden sind. Der Druckbogen hat dann beispielsweise die in Figur 3a mit 27 bezeichnete Ausbildung. Auf die vorstehend erläuterte Weise kann der Druckbogen auch mit einem Zick-Zackfalz versehen werden, wie dies in Figur 3b gezeigt ist, wo der gefalzte Druckbogen mit 28 bezeichnet ist.The cylinder 3, which is provided with a folding knife 9 which is infinitely adjustable over the cylinder circumference, leads the printed sheet B folded and held by the folding flap 8 in the circumferential direction beyond that point at which the circumference of the cylinder 3 is closest to a downstream cylinder 4 . The adjustable folding knife 9 then presses at this point to be folded for the second time, the printed sheet B into an adjustable folding flap 10 of the cylinder 4. After opening the folding flap 8, the cylinder 4 has taken over the sheet B, which has now been folded twice, and feeds the sheet held by the folding flap 10 to a further traveling cylinder 5 . A folding knife 11 of the cylinder 4 presses the sheet 13 into a folding flap 12 of the cylinder 5 at the point at which folding is to take place for the third time. The folding process explained above can be repeated as many times as interacting folding jaw and folding knife cylinders 5a, 5b etc. are present. The printed sheet then has, for example, the designation designated 27 in FIG. 3a. In the manner explained above, the printed sheet can also be provided with a zigzag fold, as shown in FIG. 3b, where the folded printed sheet is designated by 28.

Mit einem zweimaligen Querfalz erhält man 8-seitige, mit einem dreimaligen Querfalz 16-seitige ineinanderliegende Falzprodukte 27 gemäß Figur 3a. Bei einem Zick-Zackfalzprodukt 28 gemäß Figur 3b können mit drei Querfalzungen zweimal vier Seiten gebildet werden; es können aber auch mehr Seiten im 4-Seitensprung gebildet werden, wenn für jeden weiteren Querfalz ein eigener Falzklappen- und Falzmesserzylinder vorgesehen wird.With a two-fold cross fold, 8-sided, with a three-fold cross fold 16-sided interlocking products 27 according to FIG. 3a are obtained. In the case of a zigzag fold product 28 according to FIG. 3b, four sides can be formed twice with three transverse folds; however, more pages can also be formed in 4-sided jump if a separate folding jaw and folding knife cylinder is provided for each additional transverse fold.

Der fertig quergefalzte Druckbogen B wird von dem jeweils letzten Zylinder bzw. Zylinderpaar mittels absenkbarer Abweiser 14 bzw. 15 auf ein Transportband 16 abgelegt.The finished cross-folded printed sheet B is placed on a conveyor belt 16 by the last cylinder or pair of cylinders by means of lowerable deflectors 14 or 15.

Die Abweiser 14, 15 verhindern eine unbeabsichtigte Mitnahme des gefalzten Druckbogens B beim Öffnen der jeweils letzten Falzklappe, indem sie den Bogen von der Falzklappe lösen. Der gefalzte Druckbogen B wird unter einer Schlagschere 18 auf ein weiteres Transportband 17 übergeben, das den gefalzten Druckbogen B bis zu einem in Richtung der eingezeichneten Pfeile verstellbaren und anhebbaren Anschlag 19 führt. Sobald der Druckbogen B zwei außen liegende Kontaktschalter 20 an dem Anschlag 19 berührt, schneidet die Schlagschere 18 den Greiferrand bzw. die hintere Randzone des gefalzten Druckbogens ab. Wird die Erzielung eines zwei- oder mehrlagigen Produktes über die Zick-Zackfalzung erwünscht, so wird auch der hintere gefalzte Druckbogenrand, d.h. der in Figur 3b linke Falzrand, weggeschnitten, so daß nur am Rücken gefalzte Produkte verbleiben.The deflectors 14, 15 prevent unintentional entrainment of the folded printed sheet B when the last folding flap is opened by detaching the sheet from the folding flap. The folded printed sheet B is transferred under a guillotine shear 18 to another conveyor belt 17 which leads the folded printed sheet B to a stop 19 which can be adjusted and raised in the direction of the arrows. As soon as the printed sheet B If two contact switches 20 on the outside touch the stop 19, the guillotine shears 18 cuts off the gripper edge or the rear edge zone of the folded printed sheet. If it is desired to achieve a two-ply or multi-ply product via the zigzag fold, the rear folded printed sheet edge, ie the left folded edge in FIG. 3b, is also cut away, so that only products folded on the back remain.

Anschließend wird der gefalzte und in der Querrichtung geschnittene Druckbogen B nach Heben des Anschlags 19 von dem in der Querrichtung in mehrere Einzelbänder unterteilten Transportband 17 (vgl. Figur 2) und mit Hilfe von aus Figur 1 ersichtlichen Einlaufwalzen 21 seitlich verschiebbaren Kreismessem 22 mit zugeordneten Gegenmessern zugeführt, welche den quergefalzten Druckbogen B in dem erforderlichen Ausmaß längsschneiden und dadurch in der Querrichtung in einzelne nebeneinanderliegende Druckprodukte unterteilen. Das Transportband 17 führt die Druckprodukte 26 einem umlaufenden Gabelstapler 23 mit in Richtung der Pfeile verstellbaren Anlagen zu, dessen Breite der Maschinenbreite entspricht. Vom Stapler 23 werden die gestapelten Druckprodukte 26 nebeneinander angeordneten Transportbändern 24 übergeben, welche die Stapel nach links abführen. Die Transportbänder 24 sind in Richtung der eingezeichneten Pfeile um die rechte Umlenkrolle auf- und abschwenkbar, so daß die Stapel nach dem Absenken der Transportbänder auf die Bänder durchsetzende Abstützungen 25, z.B. Rollen, abgesetzt werden, über welche die Stapel zur rechten oder linken Maschinenseite abtransportiert werden.Subsequently, the folded and cut in the transverse direction cut sheet B after lifting the stop 19 from the conveyor belt 17 divided into several individual belts in the transverse direction (see FIG. 2) and with the aid of inlet rollers 21 shown in FIG. 1, circular knife 22 laterally displaceable with associated counter knives fed, which slit the cross-folded printed sheet B to the required extent and thereby divide in the transverse direction into individual print products lying next to each other. The conveyor belt 17 guides the printed products 26 to a rotating forklift 23 with systems adjustable in the direction of the arrows, the width of which corresponds to the machine width. The stacked printed products 26, which transport the stacks to the left, are transferred from the stacker 23 next to one another. The conveyor belts 24 can be swiveled up and down in the direction of the arrows around the right deflection roller, so that after the conveyor belts have been lowered onto the belts, supports 25, e.g. Rollers are set down, through which the stacks are transported to the right or left side of the machine.

Es versteht sich, daß das erläuterte Ausführungsbeispiel im Rahmen des allgemeinen Erfindungsgedankens verschiedentlich abgewandelt werden kann.It goes without saying that the exemplary embodiment explained can be modified in various ways within the scope of the general inventive concept.
