Description

Die Erfindung betrifft einen Falzapparat einer Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a folding apparatus of a printing press according to the preamble of claim 1.

Falzapparate dienen der Ausbildung von Falzen an bedruckten Bedruckstoffen, wobei bei aus dem Stand der Technik bekannten Falzapparaten ein bahnförmiger Bedruckstoff üblicherweise zuerst durch eine mindestens einen Falztrichter aufweisende erste Längsfalzeinheit geführt wird, um so am vorzugsweise noch nicht durchtrennten Bedruckstoff einen Längsfalz auszubilden. Ausgehend von der ersten Längsfalzeinheit wird der bahnförmige Bedruckstoff in Richtung auf eine Schneideinheit geführt. Im Bereich der Schneideinheit werden vom bahnförmigen Bedruckstoff Exemplare durch Querschneiden abgetrennt. Der Schneideinheit ist üblicherweise eine Querfalzeinheit nachgeordnet, die zumindest einen Falzmesserzylinder sowie einen Falzklappenzylinder umfasst. An der Schneideinheit abtrennte Exemplare werden am Falzmesserzylinder mit Hilfe von Punkturnadeln gehalten und mit Hilfe des Falzmesserzylinders in Richtung auf den Falzklappenzylinder bewegt. Die vom bahnförmigen Bedruckstoff abgetrennten Exemplare, welche am Falzmesserzylinder gehalten und vom Falzmesserzylinder in Richtung auf den Falzklappenzylinder bewegt werden, werden unter Ausbildung eines ersten Querfalzes vom Falzmesserzylinder an den Falzklappenzylinder übergeben. Weitere, zweite Querfalze sind zwischen dem Falzklappenzylinder und einem Greiferzylinder ausbildbar, der mit dem Falzklappenzylinder zusammenwirkt. Die so mit einem Längsfalz sowie mit mindestens einem Querfalz versehenen Exemplare können ausgehend von der Querfalzeinheit in den Bereich einer zweiten Längsfalzeinheit, die üblicherweise mehrere als Falztische ausgebildete Längsfalzeinrichtungen umfasst, gelangen.Folders are used for the formation of folds on printed substrates, wherein in web-fed known from the prior art, a web-like substrate is usually first passed through a first longitudinal folding unit having at least one former, so as to form a longitudinal fold on preferably not yet severed substrate. Starting from the first longitudinal folding unit, the web-shaped printing material is guided in the direction of a cutting unit. In the area of the cutting unit, copies of the web-shaped substrate are cut off by cross-cutting. The cutting unit is usually followed by a Querfalzeinheit downstream, comprising at least one folding blade and a jaw cylinder. Copies separated on the cutting unit are held on the folding blade cylinder with the help of puncturing needles and moved by means of the folding blade cylinder in the direction of the jaw cylinder. The separated from the sheet-like substrate copies, which are held on the folding blade and moved by the folding blade in the direction of the jaw cylinder, are transferred to the jaw cylinder to form a first transverse fold from the folding blade. Further, second Querfalze can be formed between the jaw cylinder and a gripper cylinder, which cooperates with the jaw cylinder. The copies thus provided with a longitudinal fold and with at least one transverse fold can, starting from the transverse folding unit, reach into the region of a second longitudinal folding unit, which usually comprises a plurality of longitudinal folding devices designed as folding tables.

Im Bereich der Falztische können an den bereits vorgefalzten Exemplaren zweite Längsfalze ausgebildet werden, die parallel zu dem in der ersten Längsfalzeinheit ausgebildeten Längsfalz verlaufen. Der zweiten Längsfalzeinheit kann eine weitere Querfalzeinheit nachgeordnet sein.In the region of the folding tables, second longitudinal folds can be formed on the already pre-folded copies which run parallel to the longitudinal fold formed in the first longitudinal folding unit. The second Längsfalzeinheit may be arranged downstream of another Querfalzeinheit.

An Stelle der ersten Längsfalzeinheit kann auch ein sogenannter Magazinaufbau vorhanden sein, wobei im Magazinaufbau keine Längsfalzung sondern eine Längstrennung des Bedruckstoffs erfolgt. Weiterhin sind Falzapparate bekannt, bei welchen der Falzmesserzylinder der Querfalzeinheit als Sammelzylinder ausgebildet ist, bei welchem in einer Sammelproduktion desselben vor der Ausbildung eines Querfalzes mehrere vom bahnförmigen Bedruckstoff durch Querschneiden abgetrennte Exemplare auf dem Falzmesserzylinder aufeinander abgelegt bzw. gesammelt werden.Instead of the first longitudinal folding unit, a so-called magazine structure may also be present, wherein in the magazine structure no longitudinal folding but longitudinal separation of the printing material takes place. Furthermore, folders are known in which the folding blade of the Querfalzeinheit is designed as a collecting cylinder, wherein in a collective production of the same before forming a Querfalzes several separated from the web-shaped substrate by cross cutting copies are stored or collected on the folding blade on each other.

Im Bereich der Querfalzeinheit werden die vom bahnförmigen Bedruckstoff abgetrennten Exemplare entlang des äußeren Umfangs der Zylinder der Querfalzeinheit und demnach entlang kreisbogenförmiger Transportstrecken bewegt. Stromabwärts der Querfalzeinheit schließt sich eine im Wesentlichen lineare Transportstrecke an, um die quergefalzten Exemplare ausgehend von der Querfalzeinheit in den Bereich der entlang der Transportstrecke positionierten Längsfalzeinheit und/oder Querfalzeinheit zu transportieren. Bei aus der Praxis bekannten Falzapparaten werden die quergefalzten Exemplare im Bereich der im Wesentlichen linearen Transportstrecke über Bänder, die mit einer konstanten Geschwindigkeit betrieben werden, geführt und im Bereich von Bremsbürsten abgebremst, um die Transportgeschwindigkeit der Exemplare an die im Bereich der linearen Transportstrecke positionierte Längsfalzeinheit und/oder Querfalzeinheit anzupassen. Beim Transport der Exemplare über Bänder sowie beim Abbremsen derselben über Bremsbürsten besteht die Gefahr, dass sich die Exemplare verdrehen und somit im Bereich der entlang der linearen Transportstrecke positionierten Längsfalzeinheit und/oder Querfalzeinheit auszubildende Falze mit einer falschen Orientierung in die Exemplare eingebracht werden. Dies ist von Nachteil.In the region of the transverse folding unit, the pieces separated from the web-shaped printing material are moved along the outer circumference of the cylinders of the transverse folding unit and therefore along arcuate transport paths. Downstream of the transverse folding unit, a substantially linear transport path follows, in order to transport the transversely folded copies starting from the transverse folding unit into the region of the longitudinal folding unit and / or transverse folding unit positioned along the transport path. In known from practice folders the cross-folded copies in the region of the substantially linear transport path via belts, which are operated at a constant speed, and braked in the range of brake brushes to the transport speed of the copies to the positioned in the region of the linear transport path Längsfalzeinheit and / or Querfalzeinheit adapt. When transporting the specimens on belts and braking them via brake brushes there is a risk that rotate the specimens and thus introduced in the region of the along the linear transport path positioned longitudinal folding unit and / or Querfalzeinheit trainees with a wrong orientation in the copies. This is a disadvantage.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen Falzapparat einer Druckmaschine zu schaffen. Diese Aufgabe wird durch einen Falzapparat gemäß Anspruch 1 gelöst. Erfindungsgemäß umfasst die im Wesentlichen lineare Transportstrecke für jedes zu transportierende Exemplar eine Führungseinrichtung sowie einen mit der Führungseinrichtung zusammenwirkenden elektrischen Linearantrieb.On this basis, the present invention has the object to provide a novel folder of a printing press. This object is achieved by a folding apparatus according to claim 1. According to the invention, the substantially linear transport path comprises a guide device for each exemplar to be transported and an electric linear drive cooperating with the guide device.

Über den elektrischen Linearantrieb können die Exemplare definiert abgebremst werden, ohne dass die Gefahr besteht, dass die Exemplare beim Transport entlang der linearen Transportstrecke verdreht werden. Auf bislang erforderliche Bänder sowie Bremsbürsten wird beim erfindungsgemäßen Falzapparat verzichtet.For the purposes of the present invention, the linear transport path, which is connected to the at least the folding blade cylinder and jaw cylinder comprehensive Querfalzeirmeit the folder, for each item to be transported a guide device and cooperating with the guide means electric linear drive. By means of the electric linear drive, the specimens can be braked in a defined manner without the risk of the specimens being twisted during transport along the linear transport path. On previously required bands and brake brushes is omitted in the folder according to the invention.

Entlang der linearen Transportstrecke 17 kann weiterhin eine Querfalzeinheit angeordnet sein, die vorzugsweise der Längsfalzeinheit 18 nachgeordnet ist.In the region of the transverse folding unit 12, transversely folded copies 16 reach, starting from the transverse folding unit 12, into the region of a substantially linear transport path 17, according to FIG Fig. 1 along the linear transport path 17 a Längsfalzeinheit 18 is arranged to form at the transversely folded copies 16 Längsfalze. Along the linear transport path 17 may further be arranged a Querfalzeinheit, which is preferably downstream of the Längsfalzeinheit 18.

Um die Exemplare 16 im Bereich der linearen Transportstrecke 17 zu führen sowie definiert abzubremsen, umfasst im Sinne der hier vorliegenden Erfindung die Transportstrecke 17 für jedes zu transportierende Exemplar 16 eine nichtdargestellte Führungseinrichtung, wobei mit jeder nicht-dargestellten Führungseinrichtung ein nicht-dargestellter elektrischer Linearantrieb zusammenwirkt.In order to guide the specimens 16 in the region of the linear transport path 17 and decelerate defined, for the purposes of the present invention, the transport path 17 for each copy 16 to be transported an unillustrated guide means, with each non-illustrated guide means, a non-illustrated electric linear drive cooperates ,

Jede Führungseinrichtung ist vom jeweiligen Linearantrieb derart antreibbar, dass ein entlang der linearen Transportstrecke zu transportierendes Exemplar 16 von einer Führungseinrichtung mit einer Relativgeschwindigkeit von in etwa null erfassbar ist.Each guide device can be driven by the respective linear drive in such a way that a copy 16 to be transported along the linear transport path can be detected by a guide device with a relative speed of approximately zero.

Weiterhin ist jede Führungseinrichtung vom jeweiligen Linearantrieb derart antreibbar, dass dieselbe zusammen mit einem von derselben erfassten Exemplar 16 definiert auf eine Geschwindigkeit abbremsbar ist, die an eine Produktionsgeschwindigkeit der entlang der Transportstrecke 17 positionierten Längsfalzeinheit 18 und/oder Querfalzeinheit angepasst ist.Furthermore, each guide device can be driven by the respective linear drive in such a way that it can be braked together with a specimen 16 detected by it to a speed which is adapted to a production speed of the longitudinal folding unit 18 and / or transverse folding unit positioned along the transport path 17.

Die Führungseinrichtungen können als Greifer ausgebildet sein, welche die Exemplare vorzugsweise im Bereich ihrer Vorderkante erfassen. Die Führungseinrichtungen können auch als Schiebeelemente oder sonstige Transportelemente ausgeführt sein.The guide devices can be designed as grippers, which preferably grip the specimens in the region of their front edge. The guide devices can also be designed as sliding elements or other transport elements.

Die Führungseinrichtungen werden nicht mit einer konstanten Geschwindigkeit betrieben, sondern vielmehr über die Linearantriebe dann, wenn dieselben ein Exemplar 16 erfassen, definiert abgebremst.
