Description

Die Erfindung betrifft einen Räderfalzapparat für eine Rollenrotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a wheel folder for a web-fed rotary printing press according to the preamble of patent claim 1.

Solche Räderfalzapparate sind in verschiedenen Bauformen bekannt. Bei 2:1-Apparaten trägt ein 2/2-großer Falzmesserzylinder zwei rotierende Falzmesser und dient zugleich als Gegenschneidzylinder mit zwei Schneidleisten und zwei Satz Punkturen zum Papiertransport. Geschnitten wird mit einem 1/2-Schneidzylinder, der einen Messerbalken trägt und zugleich als Sammelzylinder mittels einem Punkturensatz dienen kann. Vorteil dieses weit verbreiteten 2:1-Räderfalzapparates ist seine robuste, einfache und sparsame Bauweise. Nachteilig sind die Begrenzung auf maximal 112 Seiten Sammelkapazität und die Leistungsbeschränkung wegen hoher Fliehkräfte, die auf die Sammellage beim Umlauf auf dem doppelt schnell drehenden halbgroßen Schneidzylinder einwirken. So wird in US-PS 38 65 361 ein 3:2-Räderfalz beschrieben, innerhalb dessen als Hohlzylinder ausgebildetem 3/2-Sammelzylinder mit drei Satz Punkturen ein exzentrisch versetzter Falzmesserträger mit zwei Falzmessern rotiert, deren Falzmesserpitzen eine dreispitzige Hypozykloide beschreiben. Ein 2/2 großer Schneidzylinder schneidet abwechselnd mit zwei Messern gegen drei Schneidleisten, die der hohle Sammelzylinder trägt. Nachteilig ist in erster Linie bei diesem 3:2-Räderfalz die Tatsache, daß der 2/2-Schneidmesserzylinder gegen den aus konstruktiven Gründen wenig stabilen hohlen Sammelzylinder schneidet.Such wheel folder are known in various designs. In 2: 1 devices, a 2/2-sized folding knife cylinder carries two rotating folding knives and also serves as a counter-cutting cylinder with two cutting bars and two sets of punctures for paper transport. It is cut with a 1/2 cutting cylinder, which carries a cutter bar and can also serve as a collecting cylinder using a puncture set. The advantage of this widespread 2: 1 wheel folder is its robust, simple and economical construction. Disadvantages are the limitation to a maximum of 112 pages of collecting capacity and the performance limitation due to high centrifugal forces, which affect the collecting position when rotating on the double-speed, half-size cutting cylinder. For example, in US-PS 38 65 361 a 3: 2-wheel fold is described, within which a 3/2 collecting cylinder designed as a hollow cylinder with three sets of punctures rotates an eccentrically offset folding knife carrier with two folding knives, the folding knife tips of which describe a three-pointed hypocycloid. A 2/2 large cutting cylinder alternately cuts with two knives against three cutting bars which are supported by the hollow collecting cylinder. The main disadvantage of this 3: 2-wheel rebate is the fact that the 2/2 cutting knife cylinder cuts against the hollow collecting cylinder, which for structural reasons is not very stable.

Beim Schnitt starkseitiger Zeitungen treten erhebliche Schnittkräfte auf. Die Wechselbiegebeanspruchung durch Fliehkraft und Schneidkraft hat in der Praxis zu Materialermüdungen am hohlen Sammelzylinder, Haarrissen und gefährlichen Dauerbrüchen geführt.When cutting thick-sided newspapers, considerable cutting forces occur. The alternating bending stress caused by centrifugal force and cutting force has in practice led to material fatigue on the hollow collecting cylinder, hairline cracks and dangerous fatigue breaks.

Ein anderer 3:2-Räderfalz nach US-PS 31 44 249 arbeitet innerhalb des 3/2 hohlen Sammelzylinders mit drei exzentrisch versetzt umlaufenden, rotierenden Falzmessern. Auch bei dieser Konstruktion schneidet ein 2/2-Schneidzylinder gegen einen umlaufenden, hohlen 3/2-Sammelzylinder, der zugleich als Gegenschneidzylinder dient.Another 3: 2-wheel rebate according to US-PS 31 44 249 works within the 3/2 hollow collecting cylinder with three rotating offset folding knives which are offset eccentrically. With this construction too, a 2/2 cutting cylinder cuts against a rotating, hollow 3/2 collecting cylinder, which also serves as a counter-cutting cylinder.

Deshalb ist auch diese Räderfalzkonstruktion durch auftretende hohe Schnittkräfte auf dem hohlen Sammelzylinder gefährdet und anfällig für Ermüdungsbrüche. Nachteilig ist ferner der bei allen 3:2-Räderfalzen auftretende stark pulsierende Papierzug auf die einlaufenden Stränge bei Sammelproduktion, was zu ausgeschlitzten Punkturlöchern und abfliegenden Exemplaren führen kann, denn die Bahnen werden abwechseln vom Radius der nackten 3/2-Sammelzylinder-Oberfläche und dann vom durch die umlaufende - dicke - Sammellage vergrößterten Radius gezogen.This is why this wheel rebate construction is endangered by the high cutting forces that occur on the hollow collecting cylinder and is susceptible to fatigue fractures. Another disadvantage is the strong, pulsating paper tension that occurs in all 3: 2-wheel folds on the incoming strands during collective production, which can lead to slotted pinholes and flying copies, because the webs will alternate with the radius of the bare 3/2 collecting cylinder surface and then from the radius enlarged by the circumferential - thick - collecting layer.

Während beide beispielhaft genannten 3:2-Räderfalzapparate äußerlich nur zwei Falzzylinder mit je nur drei Punkturensätzen aufweisen, zeigen US-PS 41 47 337 und US-PS 41 90 242 Räderfalzapparate im System 4:4:5 mit drei Falzzylindern und drei Falztrichtern. Diese Räder falzapparate können besonders dicke Falzprodukte durch die dort beschriebene Produktionsart "Doppelt sammeln" erzeugen. Der hohle 5/2-Sammelzylinder rotiert um einen exzentrisch versetzt umlaufenden Falzmesserträger mit vier Falzmessern, um von vier verschiedenen Platten in Umfangs- bzw. Laufrichtung vier verschiedene Abschnitte aufeinander zu sammeln.While both 3: 2-wheel folder apparatuses mentioned by way of example only have two folding cylinders on the outside, each with only three puncture sets, US Pat. Nos. 4,147,337 and US Pat. These wheels Folders can produce particularly thick folding products using the "double gathering" production method described there. The hollow 5/2 collecting cylinder rotates around an eccentrically offset revolving folding knife carrier with four folding knives in order to collect four different sections of four different plates in the circumferential or running direction.

Bei diesen Apparaten erfolgt der Schnitt unabhängig vom hohlen 5/2-Sammelzylinder zwischen zwei 4/2-Massivzylindern. Der eine trägt vier Messer, der andere vier Gegenschneidleisten und vier Punkturensätze zum Weitertransport der geschnittenen Bogen auf die fünf Punkturensätze des hohlen Sammelzylinders.With these devices, the cut is made independently of the hollow 5/2 collecting cylinder between two 4/2 solid cylinders. One carries four knives, the other four counter-cutting bars and four puncture sets for further transport of the cut sheets onto the five puncture sets of the hollow collecting cylinder.

Vorteilhaft bei dieser Konstruktion ist die Tatsache, daß der hohe Schnittdruck zwischen Massivzylindern und nicht von einer rotierenden Sammelzylinderhülle aufgenommen wird. Ermüdungsbrüche können deshalb nicht vorkommen. Nachteilig ist jedoch der kostspielige und platzverbrauchende Aufwand, da 4 + 4 + 5 = 13 Armaturen auf zwei Zylindern benötigt werden. Im Fall von Stoppern müssen u.U. neun Sätze Punkturen erneuert werden, was zeitaufwendig ist.An advantage of this construction is the fact that the high cutting pressure between solid cylinders and not by a rotating cylinder sleeve is absorbed. Fatigue breaks cannot therefore occur. However, the costly and space-consuming effort is disadvantageous, since 4 + 4 + 5 = 13 fittings are required on two cylinders. In the case of stoppers, nine sets of punctures are renewed, which is time consuming.

Der Erfindung liegt die Aufgabe zugrunde, einen Räderfalzapparat für Doppel- und Sammelproduktion starker Produkte bei hohen Laufgeschwindigkeiten, d.h. einem Zylinderverhältnis größer als 2:1 zu schaffen, bei dem die hohen Schnittkräfte von massiven Zylindern aufgenommen werden.The invention has for its object to provide a gear folder for double and collective production of strong products at high running speeds, ie a cylinder ratio greater than 2: 1, in which the high cutting forces are absorbed by solid cylinders.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.The object is achieved by the features of the characterizing part of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die einlaufenden Stränge sowohl bei Doppel- als auch bei Sammelproduktion mit möglichst gleichförmigem, d.h. nicht stark pulsierendem Papierzug in die Falzzylindergruppe einlaufen können. Schließlich kann der Räderfalzapparat durch einfache, robuste, platzsparende, preiswerte und möglichst wenige Punkturen aufweisende Bauart möglichst mit bewährten Elementen ausgeführt sein, um an schnellaufenden Standard-Zeitungsmaschinen mit zwei Platten (2/2) im Umfang eingesetzt zu werden.The advantages that can be achieved with the invention are, in particular, that the incoming strands in both double and collective production with the most uniform, i.e. not heavily pulsating paper feed can enter the folding cylinder group. Finally, due to its simple, robust, space-saving, inexpensive and as few punctures as possible, the geared folder can be designed with proven elements, if possible, in order to be used on high-speed standard newspaper presses with two plates (2/2).

Ein Ausführungsbeispiel der Erfindung ist in der Figur dargesellt und wird im folgenden näher erläutert.An embodiment of the invention is shown in the figure and is explained in more detail below.

Die Figur zeigt den erfindungsgemäßen Falzapparat in Seitenansicht ohne Seitengestell.The figure shows the folder according to the invention in a side view without a side frame.

Der Räderfalzapparat nach der Erfindung besteht aus einem an sich bekannten hohlen 3/2-Sammelzylinder 1 mit drei steuerbare Punktursätze, 2, 3, 4, denen jedoch die bisher üblichen drei Papierschneidleisten fehlen. Im Inneren des hohlen 3/2-Sammelzylinders 1 rotiert ein exzentrisch versetzter Falzmesserträger 6 mit zwei oder drei rotierenden Falzmessern 7, 8, 9, deren Spitzen dreispitzige Hypozykloiden beschreiben. In bekannter Weise arbeitet die nur unten aus der 3/2-Sammelzylinderhülle 11 austretende Hypozykloidenspitze derart mit zwei Falzwalzen 12, 13 zusammen, daß bei Doppelproduktion ein Falzvorgang erfolgt und bei Sammelpro duktion die Falzmesser 7, 8, 9 nur jedes zweite vorbeilaufende Exemplar in die Falzwalzen stoßen.The wheel folder according to the invention consists of a hollow 3/2 collecting cylinder 1 known per se with three controllable point sets, 2, 3, 4, which, however, lack the three paper cutting strips customary up to now. Inside the hollow 3/2 collecting cylinder 1, an eccentrically offset folding knife carrier 6 rotates with two or three rotating folding knives 7, 8, 9, the tips of which describe three-pointed hypocycloids. In a known manner, the hypocycloid tip emerging from the bottom of the 3/2 collecting cylinder sleeve 11 works with two folding rollers 12, 13 in such a way that a folding process takes place in the case of double production and with collecting pro Production only fold the folding knives 7, 8, 9 into the folding rollers every second copy that passes by.

Dem 3/2-Sammelzylinder 1 ist auf der linken Seite ein massiver Gegenschneidzylinder 14, vorzugsweise mit zwei Schneidleisten 16, 17 und zwei steuerbaren Punktursätzen 10, 15 zugeordnet, dem ganz links außen ein massiver Schneidmesserzylinder 18, vorzugsweise mit zwei Schneidmessern 19, 20 zugeordnet ist.On the left side, the 3/2 collecting cylinder 1 is assigned a solid counter-cutting cylinder 14, preferably with two cutting bars 16, 17 and two controllable point sets 10, 15, and a massive cutting knife cylinder 18, preferably with two cutting blades 19, 20, is assigned to the far left is.

Der erfindungsgemäße 3:2:2-Räderfalzapparat - d.h. der 3/2-Sammelzylinder 1 weist drei Felder, der Gegenschneidzylinder 14 und der Schneidmesserzylinder 18 je zwei Felder auf -, unterscheidet sich wesentlich von bekannten 3:2-Falzapparaten, auch wenn das Herz der hohle 3/2-Sammelzylinder 1 mit innen exzentrisch versetzt rotierendem Falzmesserträger 6 und zwei oder drei Falzmessern 7, 8, 9, die nur unten aus der 3/2-Sammelzylinder-Oberfläche heraustreten, um dort Bogen in Falzwalzen 12, 13 zu stoßen, in bekannter und bewährter Bauart ausgeführt ist. Bei bekannten 3:2-Räderfalzen liegt der 2/2-Schneidzylinder nämlich rechts außen und dreht gegen den Uhrzeiger. Nach der Erfindung liegt der 2/2-Schneidmesserzylinder 18 links außen und dreht mit dem Uhrzeiger. Außerdem ist ein bei bekannten 3:2-Räderfalzapparaten nicht vorhandener weiterer 2/2-Massivzylinder als Gegenschneidzylinder 14 angeordnet, so daß der erfindungsgemäße Räderfalzapparat nicht wie bisher zwei, sondern drei Zylinder aufweist. Dadurch ist es möglich, die Funktion "Schneiden" völlig getrennt von den Funktionen "Sammeln" und "Falzen" ablaufen zu lassen. Folglich ist bei der erfindungsgemäßen Lösung der Aufgabenstellung jeglicher Schneiddruck gegen die rotierende Hülle 11 des 3/2-Sammelzylinders 1 entfallen.The 3: 2: 2 wheel folder according to the invention - ie the 3/2 collecting cylinder 1 has three fields, the counter-cutting cylinder 14 and the cutting knife cylinder 18 each have two fields - differs significantly from known 3: 2 folders, even if the heart the hollow 3/2 collecting cylinder 1 with an internally eccentrically rotating folding knife carrier 6 and two or three folding knives 7, 8, 9, which only emerge from the bottom of the 3/2 collecting cylinder surface in order to push sheets into folding rollers 12, 13 there , is carried out in a known and proven design. In known 3: 2-wheel folds, the 2/2 cutting cylinder is located on the right outside and turns counterclockwise. According to the invention, the 2/2 cutting knife cylinder 18 is on the left outside and rotates with the clock hand. In addition, a further 2/2 solid cylinder, which is not present in known 3: 2 wheel folding apparatuses, is arranged as a counter-cutting cylinder 14, so that the wheel folding apparatus according to the invention does not have two, but three, cylinders as previously. This makes it possible to run the "Cutting" function completely separately from the "Collect" and "Fold" functions. Consequently, in the solution of the task according to the invention, any cutting pressure against the rotating casing 11 of the 3/2-cylinder 1 is eliminated.

Der Schnitt erfolgt zwischen zwei 2/2-großen Massivzylindern 14, 18 also keinen Hohlzylindern völlig unabhängig davon, ob später in Doppel- oder Sammelproduktion gearbeitet wird. Damit ist aber auch der Papierzug gleichmäßig und nicht pulsierend.The cut is made between two 2/2-sized solid cylinders 14, 18, ie no hollow cylinders, regardless of whether later double or collective production is used. However, this also means that the paper draw is even and not pulsating.

Der erfindungsgemäße 3:2:2-Räderfalzapparat hat somit auch ähnlich günstige Eigenschaften wie der erwähnte 5:4:4-Räderfalz, erreicht dieses Ziel aber mit ganz wesentlich verringerten Kosten und fast halbiertem Platzaufwand der Zylindergruppe. Es wird bewußt auf die dritte Produktionsart "Doppelt gesammelt" verzichtet, die bei Standard-Zeitungsmaschinen mit zwei Platten im Umfang nicht gebraucht wird.The 3: 2: 2 geared folder according to the invention thus also has similarly favorable properties as the 5: 4: 4 geared fold mentioned, but achieves this goal with significantly reduced costs and almost halved space requirements of the cylinder group. The third production type "Double collected" is deliberately avoided, which is not used in standard newspaper presses with two plates.

Über Falztrichter 21, 22 werden Papierbahnen 5 längsgefalzt und die Stränge 23, 24 mit Zugwalzen 26, 27 und Vereinigungswalzen 28 auf den Gegenschneidzylinder 14 mit zwei Schneidleisten 16, 17 und zwei Satz Punkturen 10, 15 geleitet. Links davon befindet sich der Schneidmesserzylinder 18 mit zwei Schneidmessern 19, 20. Etwa 180° nach der Schnittlinie übergibt der Gegenschneidzylinder 14 der Bogen auf die Punkturen 2, 3, 4 des 3/2-Sammelzylinders 1. Im hohlen 3/2-Sammelzylinder 1 läuft exzentrisch versetzt der Falzmesserträger 6 mit zwei - oder drei - Falzmessern 7, 8, 9 um, deren Spitzen eine dreispitzige Hypozykloide beschreiben. Beide oberen Spitzen der Hypozykloide bleiben innerhalb des 3/2-Sammelzylinders 1, während die untere Spitze des Falzmessers die umlaufenden Bogen in die Falzwalzen 12, 13 stößt. Arbeiten beide Falzmesser, wird jedes ankommende Bogenpaar weggefalzt (Doppelproduktion). Wird ein Falz messer stillgelegt, so wird nur jeder zweite Abschnitt weggefalzt, während der erste Abschnitt ein zweites Mal zwecks Sammelvorgang um den 3/2-Sammelzylinder 1 herumläuft. Im Gegensatz zu anderen 3:2-Räderfalzapparaten läuft der Sammelbogen aber nicht ein zweites Mal durch die Schnittstelle. Kein Schnipseln (shredding) kann auftreten, weil der Sammelvorgang nicht mit dem Schnittvorgang kombiniert, sondern nunmehr getrennt erfolgt.Paper webs 5 are folded lengthwise via folding formers 21, 22 and the strands 23, 24 with drawing rollers 26, 27 and union rollers 28 are passed onto the counter-cutting cylinder 14 with two cutting strips 16, 17 and two sets of punctures 10, 15. To the left of this is the cutting knife cylinder 18 with two cutting knives 19, 20. About 180 ° after the cutting line, the counter-cutting cylinder 14 transfers the sheet to the punctures 2, 3, 4 of the 3/2-cylinder 1. In the hollow 3/2-cylinder 1 the eccentric knife carrier 6 runs eccentrically offset with two - or three - folding knives 7, 8, 9, the tips of which describe a three-pointed hypocycloid. Both upper tips of the hypocycloids remain within the 3/2 collecting cylinder 1, while the lower tip of the folding knife pushes the revolving sheets into the folding rollers 12, 13. If both folding knives work, each incoming pair of sheets is folded away (double production). Becomes a fold knife is shut down, only every second section is folded away, while the first section runs around the 3/2 collecting cylinder 1 a second time for the purpose of collecting. In contrast to other 3: 2 wheel folders, the collecting sheet does not run through the interface a second time. No shredding can occur because the collection process is not combined with the cutting process, but now takes place separately.

Die an sich bekannte unterschiedliche Punkturensteuerung des 3/2-Sammelzylinders je nach Produktionsart - ungesammelt, gesammelt - wird nicht weiter beschrieben. Für beide Produktionsarten ist die Punkturensteuerung von Gegenschneidzylinder 14 stets gleich mit Aufnadeln in Schnitt und Abgabe der Bogen immer an Punktursätze 2, 3, 4 des 3/2-Sammelzylinders 1.The different puncture control of the 3/2 collecting cylinder, known per se, depending on the type of production - non-collected, collected - is not described further. For both types of production, the puncture control of counter-cutting cylinder 14 is always the same with needling in cutting and delivery of the sheets always at point sets 2, 3, 4 of the 3/2-cylinder 1.

Das Zylinderverhältnis (Anzahl der Felder) von Schneidmesser-, Gegenschneidzylinder mit Bogenüoerführmittel (Punkturen) und Sammel-, Falzmesserzylinder kann auch 2:3:3 betragen. Das oben geschriebene gilt dann sinngemäß.The cylinder ratio (number of fields) of cutting knife, counter-cutting cylinder with sheet guiding means (punctures) and collecting, folding knife cylinder can also be 2: 3: 3. The above written applies accordingly.
