Description

Die Erfindung betrifft einen Falzapparat einer Rotationsdruckmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a folder of a rotary printing press according to the Preamble of claim 1.

Bei Falzapparaten ist es bekannt, Produkte an der Mantelfläche eines Falzmesserszylinders zu halten und zu einem Falzklappenzylinder zu führen. Dort werden die Produkte von einem Falzmesser unter Querfalzung in eine Falzklappe des Falzklappenzylinders übergeben. Am Mantel des Falzmesserzylinders werden die Produkte von einer Bandleitung gehalten, die von einem Schneidzylinderpaar an den Falzmesserzylinder heran bis in den Einlaufspalt zum Falzklappenzylinder führt. Beim Einstecken in die Falzklappe und deren Schließen erfolgt eine Zugwirkung auf das noch von der Bandleitung am Falzmesserzylinder festgeklemmmte Produkt. Das Produkt wird dabei elastisch gedehnt und beim Zurückgang des Falzmessers rückgedehnt. Somit wird das Produkt nicht gleichmäßig tief in die Falzklappe eingesteckt, was einen ungenauen Falz oder eine Schieffalzung zur Folge hat. Falls man mit einer verminderten Zugkraft der Bandleitung arbeitet, um ein Nachziehen des geklemmten Produktendes zu ermöglichen, besteht die Gefahr, daß die Produkte von den Bändern nicht zuverlässig erfaßt und am Falzmesserzylinder gehalten werden.In the case of folders, it is known to have products on the lateral surface of a To hold the folding knife cylinder and lead it to a folding jaw cylinder. There the products are folded from a folding knife into a folding flap of the jaw cylinder. On the jacket of the folding knife cylinder the products are held by a ribbon line, by a pair of cutting cylinders the folding knife cylinder leads into the inlet gap to the folding jaw cylinder. When inserted into the folding flap and closed, there is a pulling action the product still clamped to the folding knife cylinder by the ribbon cable. The The product is stretched elastically and when the folding knife falls rückgedehnt. This means that the product does not get evenly deep into the jaw inserted, which results in an inaccurate fold or skew fold. If one works with a reduced tensile force of the ribbon cable in order to tighten of the clamped product end, there is a risk that the Products from the belts not reliably detected and on the folding knife cylinder being held.

Es ist Aufgabe der Erfindung, einen Falzapparat zu schaffen, der eine korrekte Übergabe in die Falzklappe und somit eine genaue Falzung des Produkts ermöglicht.It is an object of the invention to provide a folder that is correct Transfer into the folding flap and thus enables an exact folding of the product.

Die Aufgabe wird erfindungsgemäß bei einem gattungsgemäßen Falzapparat mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Die zweite Bandleitung ermöglicht eine gegenüber der ersten Bandleitung andere Einstellung der Zugkraft der Bänder und kann somit an die Übergabeerfordernisse in die Falzklappe angepasst werden. Es ist dadurch ein gleichmäßiger, genauer Querfalz realisierbar. The object is achieved with a generic folder with the characterizing features of claim 1 solved. The second tape line enables a different adjustment of the tensile force compared to the first ribbon cable the belts and can thus meet the transfer requirements in the jaw be adjusted. This makes it possible to achieve a uniform, precise transverse fold.

Dabei beeinflußt eine Verstellung der Zugkraft der Bänder der zweiten Bandleitung nicht die Einstellung der ersten Bandleitung.This affects an adjustment of the tensile force of the tapes of the second tape line not the setting of the first tape line.

Weitere Vorteile und Merkmale ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.Further advantages and features emerge from the subclaims in Link with the description.

Nachfolgend soll die Arbeitsweise des Falzapparates erklärt werden. Eine von einer Rotationsdruckmaschine bedruckte und ggf. bereits längsgefalzte Bahn 23 wird beim Passieren der Schneidzylinder 8, 9 in Produkte 7 quergeschnitten, die in den Einlaufspalt 12 geführt und von den Bändern der ersten und dritten Bandleitung 10, 11 erfasst werden und dem Falzmesserzylinder 1 zugeführt werden. Dort werden die Produkte 7 kopfseitig von den Greifern 6 erfaßt und am Umfang des Falzmesserzylinders 1 bei dessen Drehung weiter transportiert. Dabei werden die Produkte 7 mittels der ersten Bandleitung 10 am Umfang des Falzmesserzylinders gehalten. Mittels der Arbeitszylinder 17 wird auf die Bänder der ersten Bandleitung 10 eine Zugkraft aufgebracht, die so bemessen ist, dass die Produkte 7 im Einlaufspalt 12 zuverlässig erfasst und bei ihrem weiteren Transport sicher am Umfang des Falzmesserzylinders 1 gehalten werden. Unter weiterer Drehung des Falzmesserzylinders 1 wird das Produkt 7 in den Einlaufspalt mit dem Falzklappenzylinder 2 geführt, wobei in diesem Bereich die zweite Bandleitung 13 die Führung am Falzmesserzylinders 1 übernimmt. In der in Figur 1 gezeigten Stellung hat gerade das Falzmesser 4 das Produkt 7 unter Bildung eines Querfalzes in die Falzklappe 5 des Falzklappenzylinders 2 eingesteckt, worauf das Falzmesser 4 wieder aus der Falzklappe 5 herausgezogen wurde. Außerdem hat bereits der Greifer 6 den Kopf des Produkts 7 freigeben. Beim Einstecken des Produktes 7 in die Falzklappe 5 hat das Produktende den Bereich der ersten Bandleitung 10 bereits verlassen. The operation of the folder will be explained below. One by one Rotary printing machine printed and possibly already longitudinally folded web 23 is at Pass the cutting cylinders 8, 9 into products 7 that are cut into the Inlet gap 12 guided and from the tapes of the first and third tape line 10, 11 are detected and fed to the folding knife cylinder 1. There are the Products 7 gripped on the head side by the grippers 6 and on the circumference of the Folding knife cylinder 1 transported further when it rotated. The Products 7 by means of the first ribbon line 10 on the circumference of the folding knife cylinder held. By means of the working cylinder 17 is on the tapes of the first tape line 10 applied a tensile force that is dimensioned so that the products 7 in Inlet gap 12 reliably detected and safe on their further transport Scope of the folding knife cylinder 1 are held. With further rotation of the Folding knife cylinder 1 is the product 7 in the inlet gap with the Folding jaw cylinder 2 guided, the second ribbon line 13 in this area Guidance on the folding knife cylinder 1 takes over. In the position shown in Figure 1 has just the folding knife 4, the product 7 to form a transverse fold in the Folding flap 5 of the folding jaw cylinder 2 is inserted, whereupon the folding knife 4th was pulled out of the flap 5 again. In addition, the Release the gripper 6 of the head of the product 7. When inserting the product 7 in the Folding flap 5, the end of the product already has the area of the first ribbon cable 10 leave.

Mittels der Druckluftminderer 16.1 und 16.2 sind die Drücke p1 und p2, mit denen die Arbeitszylinder 15.1, 15.2 mit einem Fluid, vorzugsweise Druckluft, beaufschlagt werden, einstellbar. Damit sind die Zugkräfte auf die Bänder 13.1, 13.2 und damit deren Zugkräfte und somit deren Andrückkräfte gegen den Falzmesserzylinder einstellbar. Mittels der Drücke p1 und p2 wird die Bänderandrückkraft so gewählt, dass das Produkt 7 vom Falzmesser 4 gleichmäßig in die Falzklappe 5 einbringbar ist und ein entsprechend genauer und gleichmäßiger Querfalz erzeugt wird. Die Zugkraft der Bänder 13.1 und 13.2 ist so eingestellt, dass diese bei der Falzung ein Nachziehen des Produktendes im erforderlichen Maße erlauben. Weiterhin wird das Produktende bei der Falzung nicht mehr von der ersten Bandleitung 10 geklemmt. Gewöhnlich ist die Andrückkraft der zweiten Bandleitung 13 niedriger als die der ersten Bandleitung 10. Mittels der Druckluftminderer 16.1 und 16.2 ist weiterhin in den Bändern 13.1 eine andere Zugkraft als in den Bändern 13.2 einstellbar. Es kann damit einem Schräglauf der Produkte 7 und einer nachfolgenden Schieffalzung entgegengewirkt werden. Derartige Verstellungen sind auch während des Betriebes des Falzapparates möglich. Auch bei einer Umstellung des Falzapparates, z.B. bei einer Umstellung von Deltafalz auf Doppelparallelfalz, oder bei Wechsel der Papiersorte und -dicke kann an den Druckluftminderern 16.1, 16.2 eine anpassende Verstellung der Zugspannung der Bänder 13.1, 13.2 der zweiten Bandleitung 13 vorgenommen werden.By means of the compressed air reducer 16.1 and 16.2 are the pressures p1 and p2 with which the Working cylinder 15.1, 15.2 with a fluid, preferably compressed air become adjustable. So that the tensile forces on the tapes 13.1, 13.2 and thus their tensile forces and thus their pressing forces against the folding knife cylinder adjustable. Using the pressures p1 and p2, the band pressing force is selected so that that the product 7 from the folding knife 4 can be inserted evenly into the folding flap 5 is and a correspondingly accurate and uniform cross fold is generated. The The tensile force of the tapes 13.1 and 13.2 is set so that it is a fold Allow retightening of the product end to the required extent. Furthermore, that will Product end no longer clamped by the first ribbon cable 10 during the folding. Usually, the pressing force of the second ribbon line 13 is lower than that of the first strip line 10. By means of the compressed air reducer 16.1 and 16.2 is still in the bands 13.1 a different traction than in the bands 13.2 adjustable. It can thus a skew of the products 7 and a subsequent skew fold be counteracted. Such adjustments are also made during operation of the folder possible. Even when changing the folder, e.g. at a change from delta fold to double parallel fold, or when changing the The type and thickness of paper can be adjusted to the compressed air reducers 16.1, 16.2 Adjustment of the tension of the tapes 13.1, 13.2 of the second tape line 13 be made.

Die Erfindung ist auch anwendbar, wenn die zu verarbeitende Bahn 23 bis an den Falzmesserzylinder 1 herangeführt und dort von einem mit diesem zusammenarbeitenden Schneidmesserzylinder 24 geschnitten wird. Ein solcher Schneidmesserzylinder 24 ist in Fig. 1 dünn eingezeichnet. Die erste Bandleitung 10 erstreckt sich dann lediglich am Falzmesserzylinder 1 vom Schneidmesserzylinder 24 bis zur zweiten Bandleitung 13. The invention is also applicable when the web to be processed 23 up to Folding knife cylinder 1 brought up and there by one with this cooperating cutting knife cylinder 24 is cut. Such a Cutting knife cylinder 24 is shown thin in Fig. 1. The first ribbon line 10 then extends only on the folding knife cylinder 1 from the cutting knife cylinder 24 to the second ribbon line 13.
