[Stand der Technik][State of the art]

Aus der DE 38 10 439 C1 ist ein Falzklappenzylinder mit zwei jeweils mit Falzklappen bestückten Zylinderteilen bekannt, die zur Einstellbarkeit des durch die Falzklappen bewirkten Falzvorganges eines Falzproduktes gegenseitig verdrehbar koaxial zu einer an einem Ende mittels eines Festlagers und an ihrem anderen Ende mittels eines Loslagers an einer in einem Gestell gelagerten Welle angeordnet sind. Neben einer die Verdrehung gewährleistenden Lagerung der Zylinderteile stützt sich zur axialen Fixierung eines Zylinderteiles dieses in axialer Richtung an dem anderen fest mit der Welle verbundenen Zylinderteil ab. Die dafür erforderliche axiale Passung der Zylinderteile erfordert einen entsprechenden Herstellungsaufwand. Auf Grund der funktionsbedingt erforderlichen engen Passungstoleranzen zwischen den Zylinderteilen können Passungsrost und Verschmutzungen die gegenseitige Verdrehung der Zylinderteile erschweren.From the DE 38 10 439 C1 a jaw cylinder with two each equipped with jaws cylinder parts is known, arranged for adjustability of the folding jaws caused by the folding of a folded product mutually rotatable coaxially to one at one end by means of a fixed bearing and at its other end by means of a floating bearing on a shaft mounted in a frame are. In addition to a rotation of the guaranteeing the cylinder parts is supported for the axial fixing of a cylinder part of this in the axial direction of the other firmly connected to the shaft cylinder part. The required axial fit of the cylinder parts requires a corresponding manufacturing effort. Due to the tight fit tolerances required between the cylinder parts due to their function, fretting corrosion and contamination can make it difficult to rotate the cylinder parts.

Aus der DE 44 26 987 A1 ist ein Zylinder eines Falzapparats mit den Merkmalen des Oberbegriffs des Anspruchs 1.From the DE 44 26 987 A1 is a cylinder of a folding apparatus with the features of the preamble of claim 1.

Die DE 12 79 033 B sowie die DE 15 61 073 A1 offenbaren jeweils Zylinder für einen Falzapparat mit zwei zueinander verdrehbaren Zylinderteilen, wobei ein Zylinderteil, welches mit einer Welle fest verbunden ist, im anderen Zylinderteil, welches jeweils an beiden Seitenwänden eines Gestells drehbar gelagert ist, drehbar gelagert ist.The DE 12 79 033 B as well as the DE 15 61 073 A1 each reveal cylinder for a folder with two mutually rotatable cylinder parts, wherein a cylinder part, which is fixedly connected to a shaft, rotatably mounted in the other cylinder part, which is rotatably mounted respectively on both side walls of a frame.

Die DE 38 38 314 A1 offenbart einen Zylinder eines Falzapparats, dessen Welle in zwei gegenüberliegenden Seitenwänden eines Gestells drehbar gelagert ist, wobei auf der Welle zwei zueinander verdrehbare Zylinderteile drehbar gelagert sind.The DE 38 38 314 A1 discloses a cylinder of a folder whose shaft is rotatably mounted in two opposite side walls of a frame, wherein on the shaft two mutually rotatable cylinder parts are rotatably mounted.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, einen Zylinder für Falzapparate gemäß dem Oberbegriff von Anspruch 1 zu schaffen, der den Herstellungsaufwand zur axialen Fixierung der Zylinderteile reduziert und die gegenseitige Verdrehung der Zylinderteile zu seiner Einstellbarkeit uneingeschränkt gewährleistet.The invention has for its object to provide a cylinder for folders according to the preamble of claim 1, which reduces the manufacturing cost for the axial fixing of the cylinder parts and ensures the mutual rotation of the cylinder parts to its adjustability unrestricted.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst. Ausgestaltungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit der Zeichnung.According to the invention the object is achieved by the features of claim 1. Embodiments emerge from the subclaims as well as from the description in conjunction with the drawing.

Durch die axiale Fixierung der Zylinderteile jeweils mit Hilfe eines Festlagers im Gestell ist die axiale Verschiebbarkeit mit geringem Aufwand auf eine kleine Toleranz einschränkbar, wobei sich dies auf die Qualität des Falzvorganges auf Grund des mit Schrägverzahnung ausgestalteten Antriebes der Zylinderteile positiv auswirkt. Paßarbeiten in axialer Richtung zwischen den in dieser Richtung beabstandeten Zylinderteilen entfallen.
Durch die Vermeidung von Passungsrost und Festsetzung infolge von Verschmutzungen ist eine funktionsgerechte gegenseitige Verstellung der Zylinderteile gewährleistet.Due to the axial fixation of the cylinder parts each with the aid of a fixed bearing in the frame, the axial displaceability with little effort to a small tolerance can be limited, which has a positive effect on the quality of the folding process due to the designed with helical gear drive of the cylinder parts. Paßarbeiten in the axial direction between the spaced-apart in this direction cylinder parts account.
By avoiding fretting corrosion and fixing due to contamination, a functionally correct mutual adjustment of the cylinder parts is ensured.

In Fig. 1 ist ein Zylinder 1, beispielsweise ein Falzklappenzylinder, gezeigt. Der Zylinder 1 besteht beispielsweise aus zwei Zylinderteilen 2; 3 mit daran angeordneten Funktionselementen 32; 33, hier beispielsweise zwei Falzklappen 9; 19, die in Umfangsrichtung gegeneinander verdrehbar sind, um eine Vorfalzverstellung bzw. Umstellung der Falzart, beispielsweise von einem 1/4-Falz in einen 1/3-Falz und umgekehrt, zu realisieren. Mit dem Zylinderteil I 2 wird beispielsweise der 2. Querfalz bewerkstelligt. Mit dem Zylinderteil II 3 wird beispielsweise der 1. Querfalz bewerkstelligt.In Fig. 1 a cylinder 1, for example a jaw cylinder, is shown. The cylinder 1 consists for example of two cylinder parts 2; 3 with functional elements 32 arranged thereon; 33, here for example two jaws 9; 19, which are rotatable relative to each other in the circumferential direction to realize a Vorfalzverstellung or conversion of Falzart, for example, from a 1/4 fold in a 1/3 fold and vice versa. With the cylinder part I 2, for example, the second transverse fold is accomplished. With the cylinder part II 3, for example, the first transverse fold is accomplished.

Das Zylinderteil I 2 besteht aus einem Zylinderkörper I 4, Seitenscheiben 5; 6, einer Welle 7, einem Antriebsrad 8, Falzklappen 9, einem Kurvenkörper 10 und einem Lager 11.The cylinder part I 2 consists of a cylinder body I 4, side windows 5; 6, a shaft 7, a drive wheel 8, jaws 9, a cam 10 and a bearing 11th

Das Zylinderteil II 3 besteht aus einem beispielsweise zweigeteilten Zylinderkörper II 12, der aus Zylinderelemeneten 13; 14 aufgebaut ist. Des weiteren besteht das Zylinderteil II 3 aus Seitenscheiben 15, 16, einer Hülse 17, einem Antriebsrad 18, Falzklappen 19, einem Kurvenkörper 20 und einem Lager 21.The cylinder part II 3 consists of an example, two-part cylinder body II 12, the cylinder elements 13; 14 is constructed. Furthermore, the cylinder part II 3 consists of side windows 15, 16, a sleeve 17, a drive wheel 18, jaws 19, a cam 20 and a bearing 21st

Der Zylinderkörper I 4 ist auf einer Welle 7 fest gelagert. Der Zylinderkörper I 4 ist vorzugsweise koaxial zu der Welle 7 angeordnet.
Die Welle 7 ist zwischen Seitenwänden 22; 23 eines Gestelles angeordnet, wobei die Welle 7 an der Seitenwand 23 mittels des Lagers 11 drehbar gelagert ist. Das Lager 11 ist in der Seitenwand 23 mittels einer Hülse 24, einem Distanzelement 25 und einem Deckelelement 26 axial unverschiebbar befestigt. Somit ist das Lager 11 als Festlager ausgestaltet. Auf der Hülse 24 ist der Kurvenkörper 20 gelagert. An der Seitenwand 22 ist eine Hülse 17 angeordnet, in welcher die Welle 7 aufgenommen und drehbar gelagert ist.
Endseitig ist an der Welle 7 das Antriebsrad 8 angeordnet.
Am Zylinderteil I 4 sind die Seitenscheiben 5; 6 angeordnet, zwischen denen eine oder mehrere Falzklappen 9 drehbar gelagert sind. An der Falzklappe 9 ist ein Rollenhebel 27 angeordnet. Der Rollenhebel 27 ist in der Figur 1 verdreht dargestellt.
Alternativ kann, nicht näher dargestellt, die Welle 7 auch an der Seitenwand 22 mittels des Lagers 11 gelagert sein.The cylinder body I 4 is fixedly mounted on a shaft 7. The cylinder body I 4 is preferably arranged coaxially with the shaft 7.
The shaft 7 is between side walls 22; 23 of a frame, wherein the shaft 7 is rotatably mounted on the side wall 23 by means of the bearing 11. The bearing 11 is fixed in the side wall 23 by means of a sleeve 24, a spacer element 25 and a cover member 26 axially immovable. Thus, the bearing 11 is designed as a fixed bearing. On the sleeve 24 of the cam 20 is mounted. On the side wall 22, a sleeve 17 is arranged, in which the shaft 7 is received and rotatably supported.
End side, the drive wheel 8 is arranged on the shaft 7.
On the cylinder part I 4, the side windows 5; 6, between which one or more jaws 9 are rotatably mounted. At the jaw 9, a roller lever 27 is arranged. The roller lever 27 is in the FIG. 1 shown twisted.
Alternatively, not shown in detail, the shaft 7 may also be mounted on the side wall 22 by means of the bearing 11.

Der Zylinderkörper II 12 ist auf der Welle 7 mittels Lager 28, welche als Gleitlager oder als Wälzlager ausführbar sind, gelagert. Der Zylinderkörper II 12 ist vorzugsweise koaxial zu der Welle 7 angeordnet. Der Zylinderkörper II 12 ist somit verdrehbar zum Zylinderkörper I 4 auf der Welle 7 gelagert. Am Zylinderkörper II 12, insbesondere an den Zylinderelementen 13; 14, sind die Seitenscheiben 15; 16 angeordnet, zwischen denen eine oder mehrere Falzklappen 19 drehbar gelagert sind. An der Falzklappe 19 ist ein Rollenhebel 29 angeordnet. Der Rollenhebel 29 ist in der Figur 1 verdreht dargestellt. Die Seitenscheibe 15 ist verdrehfest mit der Hülse 17 verbunden. An der Seitenwand 22 ist eine Lagerbuchse 30 befestigt, auf welcher den Kurvenkörper 10 gelagert ist. Auf der Hülse 17 ist das Lager 21 und das Antriebsrad 18 angeordnet. Die Lagerbuchse 30, ein Befestigungselement 31, beispielsweise ein Sicherungsring, das Antriebsrad 18 und die Hülse 17 hindern das Lager 21 an einem axialen gleiten. Das Lager 21 ist somit axial unverschiebbar befestigt.
Somit ist das Lager 21 als Festlager ausgeführt.The cylinder body II 12 is mounted on the shaft 7 by means of bearings 28 which are executable as plain bearings or as rolling bearings. The cylinder body II 12 is preferably arranged coaxially with the shaft 7. The cylinder body II 12 is thus rotatably mounted to the cylinder body I 4 on the shaft 7. On the cylinder body II 12, in particular on the cylinder elements 13; 14, the side windows 15; 16, between which one or more jaws 19 rotatably mounted are. At the jaw 19, a roller lever 29 is arranged. The roller lever 29 is in the FIG. 1 shown twisted. The side window 15 is rotationally connected to the sleeve 17. On the side wall 22, a bearing bush 30 is fixed, on which the cam body 10 is mounted. On the sleeve 17, the bearing 21 and the drive wheel 18 is arranged. The bushing 30, a fastener 31, for example, a circlip, the drive wheel 18 and the sleeve 17 prevent the bearing 21 at an axial slide. The bearing 21 is thus fixed axially immovable.
Thus, the bearing 21 is designed as a fixed bearing.

Der Zylinder 1, insbesondere der an der Welle 7 fest gelagerte Zylinderkörper I 4, ist rotatorisch über eine, nicht näher dargestellte, Antriebsvorrichtung antreibbar, die an dem Antriebsrad 8 angeordnet ist. Mit dem Antriebsrad 18 steht eine weitere oder die oben erwähnte, nicht näher dargestellte, Antriebsvorrichtung in Verbindung, womit der rotatorische Antrieb des Zylinderkörpers II 12 und die Verstellung in Umfangsrichtung des Zylinderkörpers II 12 zum Zylinderkörper I 4 bewerkstelligt wird.
Konstruktiv ist eine Verschiebbarkeit infolge einer axialen Beabstandung beider Zylinderkörper 4; 12 zueinander um einen Betrag A vorgesehen, wobei der Betrag A der Beabstandung der beiden Zylinderkörper 4; 12 entspricht, durch welche die Funktion der Loslager für beide Zylinderkörper 4; 12 sichergestellt wird.
Die axiale Fixierung der Zylinderteile I und II bzw. der Zylinderkörper I und II wird durch das jeweilige Lager 11; 21 in den Seitenwänden 22; 23 erreicht.
Gleichzeitig wird dadurch erreicht, dass sich die Zylinderteile und/oder Zylinderkörper nicht berühren und dadurch die Gefahr des "Festgehens" bzw. des Festsitzens infolge Rost oder anderweitiger Korrosionsschäden an den Passungen, Verschmutgung oder ähnliches von Anfang an nicht vorhanden ist.The cylinder 1, in particular the cylinder body I 4 fixedly mounted on the shaft 7, can be driven in rotation by means of a drive device, not shown, which is arranged on the drive wheel 8. With the drive wheel 18 is another or the above-mentioned, not shown, drive device in connection, whereby the rotational drive of the cylinder body II 12 and the adjustment in the circumferential direction of the cylinder body II 12 to the cylinder body I 4 is accomplished.
Constructive is a displacement due to an axial spacing of the two cylinder body 4; 12 provided to each other by an amount A, wherein the amount A of the spacing of the two cylinder body 4; 12 corresponds, by which the function of the floating bearing for both cylinder body 4; 12 is ensured.
The axial fixation of the cylinder parts I and II and the cylinder body I and II by the respective bearing 11; 21 in the side walls 22; 23 reached.
At the same time it is achieved that do not touch the cylinder parts and / or cylinder body and thus the risk of "festsein" or stuck because of rust or other corrosion damage to the fits, dirt or the like from the beginning is not present.

Für die Lager 11; 21 sollen geeignete Wälzlager, beispielsweise Schrägkugellager, Einsatz finden, dadurch läßt sich das axiale Spiel des Zylinders 1 sehr klein halten ohne größeren Fertigungsaufwand. Da das axiale Spiel des Zylinders 1 sehr gering ist, wird eine erhöhte Falz- und Schnittgenauigkeit dadurch erreicht. Dies ist beispielsweise besonders im Illustrationsdruckmaschinenbau erwünscht.
Die erfindungsgemäße Vorrichtung soll sich nicht nur auf den Einsatz bei mehrteiligen Falzzylindern beschränken. Es ist beispielsweise, nicht näher dargestellt, auch an eine Verwendung bei mehrteiligen Falzmesserzylindern, mehrteiligen Schneidzylindern oder mehrteiligen Querperforationszylindern in Falzapparaten zu denken.
Wobei bei einer Verwendung des Zylinders 1 als Falzmesserzylinder die Funktionselemente 32; 33 der Zylinderteile 2; 3 als Falzmesser oder Halteelement für das Falzprodukt ausgeführt sind.
Bei Verwendung des Zylinders 1 als Schneidzylinder sind die Funktionselemente 32; 33 der Zylinderteile 2; 3 als Schneidmesser ausgeführt.
Bei Verwendung des Zylinders 1 als Querperforationszylinder sind die Funktionselemente 32; 33 der Zylinderteile 2; 3 als Perforationsmesser ausgeführt.For the bearings 11; 21 are suitable rolling bearings, such as angular contact ball bearings, use find, thereby the axial play of the cylinder 1 can be kept very small without major manufacturing effort. Since the axial play of the cylinder 1 is very low, an increased folding and cutting accuracy is achieved. This is desirable, for example, especially in commercial printing machine construction.
The device according to the invention is not intended to be limited to use in multipart folding cylinders. It is, for example, not shown in detail, to think of a use in multi-part folding blade cylinders, multi-part cutting cylinders or multi-part Querperforationszylindern in folders.
When using the cylinder 1 as folding blade, the functional elements 32; 33 of the cylinder parts 2; 3 are designed as a folding blade or retaining element for the folded product.
When using the cylinder 1 as a cutting cylinder, the functional elements 32; 33 of the cylinder parts 2; 3 designed as a cutting blade.
When using the cylinder 1 as Querperforationszylinder the functional elements 32; 33 of the cylinder parts 2; 3 executed as Perforationsmesser.
