Falzapparatefolders
Die Erfindung betrifft Falzapparate gemäß dem Oberbegriff der Ansprüche 1, 17 oder 18.The invention relates to folders according to the preamble of claims 1, 17 or 18.
Die DD 41 520 beschreibt einen Räderfalzapparat, dessen Falzmesserbewegung mittels zweier unterschiedlicher Planetenräder zwischen zwei Betriebsarten umschaltbar ist. Eine Veränderung des Falzes am Produkt ist nicht vorgesehen.The DD 41 520 describes a gear folder, the folding blade movement of which can be switched between two operating modes by means of two different planet gears. A change in the fold on the product is not intended.
Die DE 197 55 428 A1 zeigt eine Vorrichtung zum Verstellen der Falzmechanismen an einem Falzzylinder eines Falzapparates.DE 197 55 428 A1 shows a device for adjusting the folding mechanisms on a folding cylinder of a folding apparatus.
Der Erfindung liegt die Aufgabe zugrunde, Falzapparate zu schaffen.The invention has for its object to provide folders.
Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 , 17 oder 18 gelöst.The object is achieved by the features of claims 1, 17 or 18.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass das zum Einstellen der relativen Phase des Trägers in Bezug zum Transportzylinder eingesetzte Differentialgetriebe die Phaseneinstellung ausschließlich durch Drehbewegungen und nicht durch Translationsbewegungen bewirkt, und dass die Baugröße eines Differentialgetriebes - im Gegensatz zu der eines Linearstellgliedes - unabhängig vom mit ihm realisierbaren Phasenhub ist. Im Rahmen der Erfindung einsetzbare Differentialgetriebe sind Standardteile, die in großen Mengen industriell hergestellt werden und preiswert verfügbar sind. Bevorzugte Typen solcher Differentialgetriebe sind Harmonic-Drive-Getriebe oder Planetengetriebe.The advantages that can be achieved with the invention are, in particular, that the differential gear used to set the relative phase of the carrier in relation to the transport cylinder effects the phase adjustment exclusively by means of rotary movements and not by translational movements, and that the size of a differential gear - in contrast to that of a linear actuator - is independent of the phase shift that can be achieved with it. Differential gears that can be used in the context of the invention are standard parts that are manufactured industrially in large quantities and are available inexpensively. Preferred types of such differential gears are harmonic drive gears or planetary gears.
Von den drei An- oder Abtriebsgliedern eines solchen Differentialgetriebes ist vorzugsweise eines an einen mit einer Bremse ausgestatteten Stellmotor angeschlossen. Dieser Motor ist nur in Betrieb, so lange die Phase verstellt wird; wenn der Falzapparat normal arbeitet, ist der Motor deaktiviert und die Bremse angezogen.Of the three input or output members of such a differential gear preferably one connected to a servomotor equipped with a brake. This motor is only in operation as long as the phase is adjusted; when the folder is operating normally, the motor is deactivated and the brake is applied.
Der Falzmesserzylinder des Falzapparats hat vorzugsweise eine Mehrzahl von Haltern wie etwa Greifer oder Reihen von Punkturnadeln zum Halten eines zu fördernden Produktes.The folding knife cylinder of the folder preferably has a plurality of holders such as grippers or rows of pin needles for holding a product to be conveyed.
Um die zu falzenden Produkte aus einem zusammenhängenden Produktstrang zu schneiden, wirkt der Falzmesserzylinder vorzugsweise mit einem Messerzylinder zusammen. Dabei kann die Zahl m der Messer am Messerzylinder kleiner als die Zahl n der Halter am Falzmesserzylinder sein, wenn beide durch ein Übersetzungsgetriebe mit Übersetzungsverhältnis von n/m so drehgekoppelt sind, dass sie gleiche Umfangsgeschwindigkeiten aufweisen.In order to cut the products to be folded from a coherent product strand, the folding knife cylinder preferably interacts with a knife cylinder. The number m of knives on the knife cylinder can be smaller than the number n of holders on the folding knife cylinder if both are rotationally coupled by a transmission gear with a transmission ratio of n / m so that they have the same peripheral speeds.
Um die Falzmesser innerhalb des Falzmesserzylinders ungehindert bewegen zu können, ist ihre Zahl zweckmäßigerweise ebenfalls kleiner als die Zahl n der Halter. Wenn sie gleich der Zahl m der Messer am Messerzylinder gewählt ist, kann der Träger in einfacher Weise an den Messerzylinder durch das Differentialgetriebe mit Übersetzungsverhältnis 1 :1 gekoppelt sein.In order to be able to move the folding knives unhindered within the folding knife cylinder, their number is also expediently smaller than the number n of the holders. If it is chosen equal to the number m of knives on the knife cylinder, the carrier can be coupled to the knife cylinder in a simple manner by the differential gear with a transmission ratio of 1: 1.

Im Trommelmantel 01 des in Fig. 1 gezeigten Falzmesserzylinders 18 sind drei Gruppen von Schlitzen 02 jeweils in einem Winkelabstand von 120° in Umfangsrichtung gebildet. An der in der Fig. 1 oben liegenden Gruppe von Schlitzen 02 ist eine Mehrzahl austretender Vorsprünge 03 gezeigt, die Spitzen eines Falzmessers 04 sind. Das Falzmesser 04 ist an einem Träger 20 im Inneren des Falzmesserzylinders 18 befestigt, der mit Bezug auf Fig. 2 noch genauer erläutert wird.In the drum jacket 01 of the folding knife cylinder 18 shown in FIG. 1, three groups of slots 02 are formed at an angular distance of 120 ° in the circumferential direction. On the group of slits 02 lying at the top in FIG. 1, a plurality of emerging projections 03 are shown, which are tips of a folding knife 04. The folding knife 04 is fastened to a carrier 20 in the interior of the folding knife cylinder 18, which will be explained in more detail with reference to FIG. 2.
Der Falzmesserzylinder 18 trägt ferner drei in Umfangsrichtung gleichmäßig verteilte Leisten mit ausfahrbaren Punkturnadeln 05. Diese Leisten können auch durch Greifer oder andere Mittel zum Halten eines zu falzenden Produktes am Trommelmantel 01 ersetzt sein. An den Stirnflächen des Trommelmantels 01 befinden sich zwei Flansche 06 mit einer geräumigen, zur Längsachse des Trommelmantels 01 konzentrischen Öffnung 07. An die Öffnung 07 ist ein Schaft 08 (siehe Fig. 4 und 5) angefügt, der zur drehbaren Lagerung des Falzmesserzylinders 18 im (in der Figur nicht dargestellten) Gestell eines Falzapparates dient.The folding knife cylinder 18 also carries three circumferentially evenly distributed Last with extendable pin needles 05. These lasts can also be replaced by grippers or other means for holding a product to be folded on the drum jacket 01. On the end faces of the drum jacket 01 there are two flanges 06 with a spacious opening 07 which is concentric with the longitudinal axis of the drum jacket 01. A shaft 08 (see FIGS. 4 and 5) is attached to the opening 07 and is used for the rotatable mounting of the folding knife cylinder 18 in Frame (not shown in the figure) of a folder is used.
Eine Welle 09, die den innerhalb des Falzmesserzylinders 18 angeordneten Träger 20 der Falzmesser 04 trägt, erstreckt sich exzentrisch durch die Öffnung 07.A shaft 09, which carries the carrier 20 of the folding knives 04 arranged inside the folding knife cylinder 18, extends eccentrically through the opening 07.
Fig. 2 zeigt den Aufbau dieses Trägers 20. Die Welle 09 trägt im Inneren des Falzmesserzylinders 18 zwei in entgegengesetzte Richtungen abstehende Arme 11 und eine Getriebeeinheit 12, die zwei um zur Welle 09 parallele Achsen drehbare Falzmesserwellen 13; 14 tragen. Das Gehäuse 17 der Getriebeeinheit 12 ist mit dem dem Betrachter in Fig. 2 zugewandten Abschnitt der Welle 09 starr verbunden und im Inneren des Falzmesserzylinders gemeinsam mit diesem Abschnitt drehbar. Jenseits der Getriebeeinheit 12 in der Perspektive der Fig. 2 ist die Welle 09 durch einen Wellenabschnitt 16 verlängert, der in Bezug auf das Gehäuse 17 der Getriebeeinheit 12 drehbar ist. Wenn die Getriebeeinheit 12 um die Achse der Welle 09 gedreht wird, treibt ein mit dem Wellenabschnitt 16 fest verbundenes (nicht dargestelltes) Zahnrad im Inneren der Getriebeeinheit 12 eine Drehung der Falzmesserwellen 13; 14 an.2 shows the structure of this carrier 20. The shaft 09 carries two arms 11 projecting in opposite directions in the interior of the folding knife cylinder 18 and a gear unit 12, which has two folding knife shafts 13; 14 wear. The housing 17 of the gear unit 12 is rigidly connected to the section of the shaft 09 facing the viewer in FIG. 2 and can be rotated together with this section in the interior of the folding knife cylinder. Beyond the gear unit 12 in the perspective of FIG. 2, the shaft 09 is extended by a shaft section 16 which is rotatable with respect to the housing 17 of the gear unit 12. When the gear unit 12 is rotated about the axis of the shaft 09, a gearwheel (not shown) fixedly connected to the shaft section 16 drives a rotation of the folding blade shafts 13; 14 on.
Die schematische Seitenansicht der Fig. 3 veranschaulicht einerseits den Gesamtaufbau eines Falzapparates, der den mit Bezug auf die Fig. 1 und 2 beschriebenen Falzmesserzylinder 18 aufweist, sowie die Bewegung der Falzmesser 04 innerhalb des Falzmesserzylinders 18 im Betrieb des Falzapparates.The schematic side view of FIG. 3 illustrates on the one hand the overall structure of a folding apparatus which has the folding knife cylinder 18 described with reference to FIGS. 1 and 2, and the movement of the folding knife 04 within the folding knife cylinder 18 during operation of the folding apparatus.
Zunächst wird der Aufbau des Falzapparates kurz erläutert. Der Falzmesserzylinder 18 ist in Kontakt mit einem Messerzylinder 19 drehbar aufgehängt. Der Messerzylinder 19 trägt zwei Schneidmesser 21 , die zusammenwirkend mit dem Falzmesserzylinder 18 eine Materialbahn 22, z. B. eine Papierbahn 22, in einzelne Produkte oder Signaturen 31 auftrennen. Diese Papierbahn 22 ist dem vom Falzmesserzylinder 18 und Messerzylinder 19 gebildeten Spalt von einem (nicht gezeigten) Falztrichter aus über ein Paar Zug- und Führungsrollen 23 zugeführt. Das Verhältnis der Drehzahlen von Messerzylinder 19 zu Falzmesserzylinder 18 ist 3 : 2, und ihre relative Phase ist so eingestellt, dass ein Schneidmesser 21 die Papierbahn 22 jeweils kurz vor einer Leiste von Punkturnadeln 05 des Falzmesserzylinders 18 durchtrennt. Das so entstandene führende Ende der Papierbahn 22 wird von den Punkturnadeln 05 aufgespießt und bei der Umdrehung des Falzmesserzylinders 18 im Uhrzeigersinn in Fig. 3 an seiner Oberfläche weiter gefördert.First, the structure of the folder is briefly explained. The folding knife cylinder 18 is suspended rotatably in contact with a knife cylinder 19. The knife cylinder 19 carries two cutting knives 21 which cooperate with the folding knife cylinder 18 a material web 22, for. B. a paper web 22, separate into individual products or signatures 31. This paper web 22 is fed to the gap formed by the folding knife cylinder 18 and knife cylinder 19 from a folding former (not shown) via a pair of pulling and guiding rollers 23. The ratio of the speeds of the knife cylinder 19 to the folding knife cylinder 18 is 3: 2, and their relative phase is set such that a cutting knife 21 cuts the paper web 22 shortly before a strip of pin needles 05 of the folding knife cylinder 18. The resulting leading end of the paper web 22 is impaled by the puncture needles 05 and is further conveyed on its surface as the folding knife cylinder 18 rotates clockwise in FIG. 3.
Auf je zwei Umdrehungen des Falzmesserzylinders 18 um seine Achse 24 kommen drei Umdrehungen des Trägers 20 bzw. drei Umläufe der Falzmesserwellen 13; 14 um die Träger-Achse 26. In jedem Umlauf der Falzmesserwellen 13; 14 führen die daran montierten Falzmesser 04 zwei Umdrehungen um die Achse 27 bzw. 28 der Falzmesserwellen 13; 14 aus. Die Spitzen der Falzmesser 04 bewegen sich daher auf einer durch eine strichpunktierte Linie dargestellten Bahn 29, die in etwa die Form eines Dreiecks mit konkaven Seiten hat. Die untere Spitze dieser dreieckigen Bahn 29 liegt außerhalb des Umfangs des Falzmesserzylinders 18, an dieser Stelle treten die Falzmesser 04 aus dem Falzmesserzylinder 18 aus, um eine von der Papierbahn 22 abgeschnittene Signatur 31 in einen Spalt zwischen zwei Falzrollen 32 einzuführen. Unterhalb des Spaltes befindet sich ein Schaufelrad 33, in dessen Schaufeln die gefalzten Signaturen 31 hineinfallen, um anschließend auf ein Förderbahn 34 ausgelegt zu werden.For every two revolutions of the folding blade cylinder 18 about its axis 24, there are three revolutions of the carrier 20 or three revolutions of the folding blade shafts 13; 14 around the carrier axis 26. In each revolution of the folding knife shafts 13; 14 the folding knives 04 mounted thereon make two revolutions about the axes 27 and 28 of the folding knife shafts 13; 14 out. The tips of the folding knives 04 therefore move on a path 29 represented by a dash-dotted line, which has approximately the shape of a triangle with concave sides. The lower tip of this triangular web 29 lies outside the circumference of the folding knife cylinder 18, at this point the folding knives 04 emerge from the folding knife cylinder 18 in order to insert a signature 31 cut from the paper web 22 into a gap between two folding rollers 32. Below the gap there is a paddle wheel 33, in the blades of which the folded signatures 31 fall in order to be subsequently laid out on a conveyor track 34.
Fig. 4 zeigt ein erstes Ausführungsbeispiel für die Antriebsstruktur des Falzapparates aus Fig. 3. Der Falzmesserzylinder 18 und der Messerzylinder 19 sind drehbar zwischen Seitengestellplatten 36 des Falzapparates aufgehängt.

Eine der Hülsen 48 ist drehfest mit der Welle 41 verbunden, während die andere Hülse 47 fest mit einem um die Welle 41 drehbaren Zahnrad 49 verbunden ist, das mit einem Zahnrad 51, z. B. einem Antriebszahnrad 51 des Trägers 20 kämmt.One of the sleeves 48 is rotatably connected to the shaft 41, while the other sleeve 47 is fixedly connected to a gear 49 rotatable about the shaft 41, which with a gear 51, z. B. meshes a drive gear 51 of the carrier 20.
Die Zahnzahlen der Zahnräder 37; 39 sind so gewählt, dass sie ein Drehzahlverhältnis des Messerzylinders 19 zum Falzmesserzylinder 18 von 3 : 2 gewährleisten. Die Zahnzahlen der Hülsen 47; 48 und der Zahnräder 49; 51 sind jeweils untereinander gleich, so dass, so lange der Stellmotor 43 steht, der Messerzylinder 19 und der Träger 20 mit gleicher Drehzahl rotieren. Um zu gewährleisten, dass die relative Phase von Messerzylinder 19 und Träger 20 im Betrieb des Falzapparates konstant gehalten werden kann, ist der Stellmotor 43 mit einer Bremse ausgestattet, die in der Lage ist, eine Drehung des Rotors 42 zu unterbinden. WThe number of teeth of the gears 37; 39 are selected so that they ensure a speed ratio of the knife cylinder 19 to the folding knife cylinder 18 of 3: 2. The number of teeth of the sleeves 47; 48 and the gears 49; 51 are in each case identical to one another, so that, as long as the servomotor 43 is stationary, the knife cylinder 19 and the carrier 20 rotate at the same speed. In order to ensure that the relative phase of knife cylinder 19 and carrier 20 can be kept constant during the operation of the folder, the servomotor 43 is equipped with a brake which is able to prevent the rotor 42 from rotating. W
Durch Drehen des Rotors 42 ist die Phase der Bewegung der Falzmesser 04 auf ihrer Bahn 29 in Bezug auf die Phase der Drehung des Falzmesserzylinders 18 verstellbar. Das heißt, die Lage des Ortes, an welchem die Falzmesser 04 aus dem Trommelmantel 01 austreten, ist in Bezug auf die Punkturnadeln 05 verstellbar. In einer Normalstellung, wie in Fig. 6A gezeigt, liegt der Austrittsort der Falzmesser 04 exakt mittig zwischen den zwei Enden der am Falzmesserzylinder 18 geförderten Signatur 31 , und die fertig gefalzte Signatur 31 , die rechts in der Fig. 6A gezeigt ist, hat beiderseits der Falzlinie gleich lange Schenkel.By rotating the rotor 42, the phase of the movement of the folding knives 04 on their path 29 can be adjusted with respect to the phase of the rotation of the folding knife cylinder 18. This means that the position of the location at which the folding knives 04 emerge from the drum jacket 01 is adjustable with respect to the puncture needles 05. In a normal position, as shown in FIG. 6A, the exit location of the folding knife 04 lies exactly in the middle between the two ends of the signature 31 conveyed on the folding knife cylinder 18, and the finished folded signature 31, which is shown on the right in FIG. 6A, has on both sides Legs of equal length to the fold line.
Wird die Phase der Falzmesserbewegung gegenüber der des Falzmesserzylinders 18 verzögert, wie in Fig. 6B gezeigt, so entsteht eine asymmetrisch gefalzte Signatur 31 , bei der der von den Punkturnadeln 05 gehaltene Schenkel, erkennbar an Einstichlöchern 52, länger als der in Förderrichtung nacheilende Schenkel ist.If the phase of the folding knife movement is delayed compared to that of the folding knife cylinder 18, as shown in FIG. 6B, an asymmetrically folded signature 31 is created, in which the leg held by the puncture needles 05, recognizable by puncture holes 52, is longer than the leg lagging in the conveying direction ,
Durch Vorziehen der Phase der Falzmesserbewegung, in Fig. 6C gezeigt, wird eine entgegengesetzte Asymmetrie erreicht.By advancing the phase of the folding knife movement, shown in Fig. 6C, an opposite asymmetry is achieved.
Fig. 5 zeigt ein zweites Ausführungsbeispiel für die Antriebsstruktur des Falzapparates. Elemente, die in Fig. 5 mit den gleichen Bezugszeichen wie in Fig. 4 bezeichnet sind, sind mit den mit Bezug auf Fig. 4 beschriebenen Elementen identisch und werden nicht erneut beschrieben. Die Welle 41 des Messerzylinders 19 trägt an ihrem vom Hauptmotor 38 abgewandten Ende ein Sonnenrad 53 eines Planetengetriebes. Ein Planetenträger 54 von mit dem Sonnenrad 53 kämmenden Planetenrädern 56 ist auf der Antriebswelle des Stellmotors 43 montiert.

Elements denoted by the same reference numerals in FIG. 5 as in FIG. 4 are identical to the elements described with reference to FIG. 4 and will not be described again. The shaft 41 of the knife cylinder 19 carries a sun gear 53 of a planetary gear at its end facing away from the main motor 38. A planet carrier 54 of planet gears 56 meshing with the sun gear 53 is mounted on the drive shaft of the servomotor 43. A ring gear 57 of the planetary gear is rotatably connected to the gear 49, which meshes with the drive gear 51 of the carrier 20.
Da die Zahnzahl des Sonnenrades 53 kleiner als die des Hohlrades 57 ist, rotiert das Hohlrad 57 bei angezogener Bremse des Stellmotors 43 langsamer als das Sonnenrad 53. Die Zahnzahlen der Zahnräder 49; 51 sind so gewählt, dass sich für das gesamte Differentialgetriebe ein Drehzahlverhältnis von 1 : 1 zwischen der Welle 41 und dem Träger 20 ergibt.Since the number of teeth of the sun gear 53 is smaller than that of the ring gear 57, the ring gear 57 rotates more slowly than the sun gear 53 when the servomotor 43 has the brake applied. The number of teeth of the gear wheels 49; 51 are chosen so that for the whole Differential gear results in a speed ratio of 1: 1 between the shaft 41 and the carrier 20.
