B. three-part folding knife and transport cylinder 2 for Signatures, which both a z. B. two parts Cutting cylinder 3 and a z. B. two parts Folding jaw cylinder 4 can be assigned. The Folding knife and transport cylinder 2 can be used as Collecting cylinders can be executed.

Der Falzklappenzylinder 4 weist zwei um 180° an seinem Umfang versetzt zueinander angeordnete Reihen von Falzklappen 6, 7 auf.
Der Schneidzylinder 3 weist zwei um 180° an seinem Umfang versetzt zueinander angeordnete Schneidmesser enthaltende Schneidleisten 8, 9 auf.
The jaw cylinder 4 has two rows of jaws 6, 7 which are offset by 180 ° on its circumference.
The cutting cylinder 3 has two cutting bars 8, 9 which are arranged at 180 ° on their circumference and are offset from one another.

Die Schneidleisten 8, 9 wirken wiederum mit auf dem Umfang des Falzmesser- und Transportzylinders 2 befindlichen, zueinander jeweils um 120° versetzten Gegenschneidleisten 11, 12, 13 zusammen.
In Uhrzeigerdrehrichtung A des nachfolgend als Zylinder 2 bezeichneten Falzmesser- und Transportzylinders 2 gesehen und jeweils vor der Gegenschneidleiste 11, 12, 13 befindet sich eine Reihe von Punktursystemen 16, 17, 18. Jedes Punktursystem 16, 17, 18 besteht aus einer Punkturwelle 19 zur formschlüssigen Aufnahme einer Reihe von Punkturhebeln 21 mit Punkturnadeln 22 sowie aus einem mit der Punkturwelle 19 formschlüssig in Verbindung stehenden Rollenhebel 23, der am freien Ende eine Kurvenrolle 24 trägt.
The cutting strips 8, 9 in turn interact with counter-cutting strips 11, 12, 13 located on the circumference of the folding knife and transport cylinder 2, each offset by 120 ° to one another.
Seen in the clockwise direction of rotation A of the folding knife and transport cylinder 2, hereinafter referred to as cylinder 2, and in front of the counter-cutting bar 11, 12, 13 there is a series of puncture systems 16, 17, 18. Each puncture system 16, 17, 18 consists of a puncture shaft 19 for positive reception of a series of puncture levers 21 with puncture needles 22 and a roller lever 23 which is positively connected to the puncture shaft 19 and carries a cam roller 24 at the free end.

Zwischen den Punktursystemen 16, 17, 18 und beabstandet von diesen sind in bekannter Weise am Umfang des Zylinders 2 jeweils um 120° versetzte Falzmessersysteme 26, 27, 28 angeordnet. Jedes Falzmessersystem 26, 27, 28 besteht aus einer Falzmesserwelle 29 mit Falzmesserhaltern 31, welche Falzmesser 32 halten, sowie aus einem auf der Falzmesserwelle 29 befestigten Rollenhebel 33, der am freien Ende eine Kurvenrolle 34 trägt (Fig. 1).Between the puncture systems 16, 17, 18 and spaced of these are known in the scope of the Cylinder 2 folding knife systems offset by 120 ° 26, 27, 28 arranged. Each folding knife system 26, 27, 28 consists of a folding knife shaft 29 with Folding knife holders 31, which hold folding knives 32, as well from a fastened on the folding knife shaft 29 Roller lever 33, a cam roller 34 at the free end carries (Fig. 1).

Die Kurvenrollen 24 der Punktursysteme 16 bis 18 laufen jeweils auf einer Steuerfläche einer Steuerkurve 36 und die Kurvenrollen 34 der Falzmessersysteme 26 bis 28 jeweils auf einer Steuerfläche einer Steuerkurve 37 ab. Jede Steuerkurve 36, 37 besteht aus einer Scheibe und weist am Umfang schaltende und nichtschaltende Steuerflächen, z. B. jeweils um 180° versetzte Kurventäler 38, 39 bzw. 41, 42 auf.
Beide Steuerkurven 36, 37 sind miteinander verbunden-z. B. stoffschlüssig - und in der Nähe einer Tragscheibe 43 des Zylinders 2 drehbar auf einem Zylinderzapfen 44 des Zylinders 2 gelagert. Dies erfolgt dadurch, daß die Steuerkurven 36, 37 an einer Stirnseite eines ersten Endes eines koaxial auf dem Zylinderzapfen 44 mittels Wälzlagern 46, 47 drehbar angeordneten buchsenförmigen Steuerkurventrägers 48 befestigt sind. Am zweiten Ende des Steuerkurventrägers 48 ist ein Zahnrad 49 drehfest befestigt, welches in der Nähe eines Seitengestells 51 mit einem auf einem Zylinderzapfen 52 des Schneidzylinders 3 befestigten Zahnrad 53 kämmt.
Eine übersetzung der Zahnräder 49, 53 zueinander beträgt z. B. 1 : 1, so daß der Steuerkurventräger 48 und somit die Steuerkurven 36, 37 mit der Drehzahl des Schneidzylinders 3 angetrieben werden. Die Drehzahl der Steuerkurven 36, 37 beträgt entsprechend dem Quotienten der Anzahl der Felder von Zylinder 2 (= 3 Felder) zu Zylinder 4 (= 2 Felder), z. B. dem 1,5-fachen der Drehzahl des Sammelzylinders 2.
The cam rollers 24 of the puncture systems 16 to 18 each run on a control surface of a control cam 36 and the cam rollers 34 of the folding blade systems 26 to 28 each run on a control surface of a control cam 37. Each control cam 36, 37 consists of a disc and has switching and non-switching control surfaces on the circumference, for. B. in each case offset by 180 ° curved valleys 38, 39 and 41, 42.
Both control curves 36, 37 are connected to each other - e.g. B. cohesively - and rotatably mounted near a support plate 43 of the cylinder 2 on a cylinder journal 44 of the cylinder 2. This takes place in that the control cams 36, 37 are attached to an end face of a first end of a bush-shaped control cam carrier 48 which is rotatably arranged coaxially on the cylinder journal 44 by means of roller bearings 46, 47. At the second end of the cam carrier 48, a gear 49 is rotatably fixed, which meshes near a side frame 51 with a gear 53 attached to a cylinder pin 52 of the cutting cylinder 3.
A translation of the gears 49, 53 to each other is z. B. 1: 1, so that the cam carrier 48 and thus the control curves 36, 37 are driven at the speed of the cutting cylinder 3. The speed of the control curves 36, 37 is according to the quotient of the number of fields from cylinder 2 (= 3 fields) to cylinder 4 (= 2 fields), z. B. 1.5 times the speed of the collecting cylinder 2nd

Die Zylinderzapfen 44, 52 der Zylinder 2, 3 sind mittels Wälzlagern 54, 56 im Seitengestell 51 gelagert und außerhalb des Seitengestells 51 drehfest mit Antriebszahnrädern 57, 58 verbunden. Der Falzklappenzylinder 4 ist mittels eines Zahnrades 55 antreibbar. Die Zahnräder 55, 57, 58 sind so dimensioniert, daß sich die Drehzahlen der anzutreibenden Zylinder 4 (= 2 Felder), 2 (= 3 Felder)-entsprechend ihrer Felder -, 3 (= 2 Felder) wie 1,5 : 1 : 1,5 verhalten.The cylinder pins 44, 52 of the cylinders 2, 3 are by means of Rolling bearings 54, 56 stored in the side frame 51 and outside of the side frame 51 rotatably with Drive gears 57, 58 connected. The The jaw cylinder 4 is by means of a gear 55 drivable. The gears 55, 57, 58 are like this dimensioned that the speeds of the cylinders to be driven 4 (= 2 fields), 2 (= 3 fields) corresponding of their fields -, 3 (= 2 fields) like 1.5: 1: 1.5 behavior.

Die Steuerung arbeitet bei Doppelproduktion, d. h. bei nicht gesammelter Produktion wie folgt:
Auf dem Zylinder 2 befindet sich eine von dem Punktursystem 18 aufgenadelte Signatur 59, während das Punktursystem 17 den Anfang 60 eines Papierstranges fördert (Fig. 1).
Nach 240° Drehbewegung des Zylinders 2 hat das Punktursystem 17 den Papierstranganfang 60 soweit gefördert, daß die Kurvenrolle 24 des Punktursystems 17 in das Kurvental 38 der inzwischen um 360° gedrehten Steuerkurve 36 eingetaucht und die Punkturnadeln 22 unter die Oberfläche des Zylinders 2 zurückgezogen sind (Fig. 2). Gleichzeitig hat das Falzmessersystem 26 infolge der 240° Drehbewegung des Zylinders 2 die Falzstelle gegenüber den Falzklappen 7 des Falzklappenzylinders 4 erreicht. Infolge der zwischenzeitlichen Drehung der Steuerkurve 37 um 360° taucht die Kurvenrolle 34 in das Kurvental 41 der Steuerkurve 37 ein, so daß das Falzmesser 32 des Falzmessersystems 26 betätigt und somit die Signatur 59 gefalzt wird (Fig. 2). Die Signatur 59 ist zwischenzeitlich gefalzt und befindet sich in den Falzklappen 6 des Falzklappenzylinders 4.
Eine weitere Signatur 59 befindet sich ebenfalls auf dem Zylinder 2 sowie ein neuer Papierstranganfang 60.
The control works in the case of double production, ie when production is not collected, as follows:
On the cylinder 2 there is a signature 59 needled by the puncture system 18, while the puncture system 17 conveys the start 60 of a paper strand (FIG. 1).
After a 240 ° rotary movement of the cylinder 2, the puncture system 17 has promoted the start of the paper strand 60 to such an extent that the cam roller 24 of the puncture system 17 is immersed in the curve 38 of the control cam 36, which has meanwhile been rotated through 360 °, and the puncture needles 22 have been withdrawn below the surface of the cylinder 2 ( Fig. 2). At the same time, the folding knife system 26 has reached the folding point relative to the folding jaws 7 of the folding jaw cylinder 4 as a result of the 240 ° rotary movement of the cylinder 2. As a result of the intermediate rotation of the control curve 37 by 360 °, the cam roller 34 dips into the cam 41 of the control curve 37, so that the folding knife 32 of the folding knife system 26 is actuated and the signature 59 is thus folded (FIG. 2). The signature 59 has been folded in the meantime and is located in the jaws 6 of the jaw cylinder 4.
Another signature 59 is also located on the cylinder 2 and a new paper strand start 60.

Soll mit dem Falzapparat 1 eine Sammelproduktion durchgeführt werden, so werden den am Steuerkurventräger 48 angeordneten Steuerkurven 36, 37 Deckscheiben 62, 63 zugeordnet. Die Deckscheibe 62 ist der Steuerkurve 37 für die Falzmessersysteme 26 bis 28 und die Deckscheibe 63 ist der Steuerkurve 36 für die Punktursysteme 16 bis 18 zugeordnet.
Die Deckscheiben 62, 63 sind kreisrund ausgeführt, haben den gleichen Durchmesser wie die Steuerkurven 36, 37 und weisen an ihrem Umfang jeweils z. B. nur ein Kurvental auf. Die Deckscheiben 62, 63 sind miteinander verbunden sowie drehfest und koaxial auf dem Steuerkurventräger 48 angeordnet.
If a collective production is to be carried out with the folder 1, the control cams 36, 37 arranged on the control cam carrier 48 are assigned cover plates 62, 63. The cover plate 62 is assigned to the control curve 37 for the folding knife systems 26 to 28 and the cover plate 63 is assigned to the control curve 36 for the puncture systems 16 to 18.
The cover plates 62, 63 are circular, have the same diameter as the control cams 36, 37 and have z. B. only one curve. The cover plates 62, 63 are connected to one another and are arranged in a rotationally fixed and coaxial manner on the cam carrier 48.

Es ist auch möglich, die Deckscheiben 62, 63 verdrehfest auf einem buchsenartigen Deckscheibenträger 64 aber in axialer Richtung verschiebbar auf dem Steuerkurventräger 48 anzuordnen. Dabei ist der Deckscheibenträger 64 mittels einer geeigneten Verschiebeeinrichtung, z. B. einer Verschiebeklaue 65, welche in eine im Deckscheibenträger 64 umlaufende Nut 74 eingreift, sowohl in Richtung Steuerkurven 36, 37 als auch in Richtung Seitengestell 51 verschiebbar.
Somit sind die Steuerkurven 36, 37 sowie 62, 63 antreibbar und rotierbar indirekt auf dem Zylinderzapfen 44 verschiebbar angeordnet. Es ist auch eine direkte Lagerung der Steuerkurven 36, 37, 62, 63 auf dem Zylinderzapfen 44 möglich.
It is also possible to arrange the cover disks 62, 63 in a rotationally fixed manner on a bush-like cover disk support 64 but displaceably in the axial direction on the control cam carrier 48. The cover plate carrier 64 is by means of a suitable displacement device, for. B. a sliding claw 65, which engages in a circumferential groove 74 in the cover plate carrier 64, can be displaced both in the direction of the control curves 36, 37 and in the direction of the side frame 51.
Thus, the control curves 36, 37 and 62, 63 are drivable and rotatably arranged indirectly displaceable on the cylinder pin 44. A direct mounting of the control cams 36, 37, 62, 63 on the cylinder pin 44 is also possible.

Werden die Deckscheiben 62, 63 in Richtung Steuerkurven 36, 37 verschoben, so kommt die Deckscheibe 63 für die Punktursysteme 16 bis 18 mit einer Kurvenrolle 66 in Verbindung. Die Kurvenrolle 66 wird ebenso von einer Kurvenrollachse 67 aufgenommen wie die Kurvenrolle 24. Ebenso ist auf einer Kurvenrollenachse 68 der Kurvenrolle 34 noch eine zweite Kurvenrolle 69 aufgenommen, welche mit der Deckscheibe 62 in Verbindung steht. Durch den Synchronlauf der Kurvenrollen 24, 66 bzw. 34, 69 wird jeweils ein von den Deckscheiben 63, 62 abgedecktes Kurvental der Steuerkurven 36, 37 abgedeckt und es erfolgt ein Sammeln der Signaturen auf dem Zylinder 2.Are the cover plates 62, 63 in the direction of the control curves 36, 37 moved, the cover plate 63 comes for Puncture systems 16 to 18 with a cam roller 66 in Connection. The cam roller 66 is also one Cam roll axis 67 is recorded as cam roll 24. Likewise, on a cam roller axis 68 Cam roller 34 and a second cam roller 69 added, which in connection with the cover plate 62 stands. Through the synchronous running of the cam rollers 24, 66 or 34, 69 is one of the cover plates 63, 62 covered curve of the control curves 36, 37 covered and the signatures are collected on the Cylinder 2.

Die Verschiebeklaue 65 kann mittels einer Linearführung 71 im Seitengestell 51 geführt und z. B. mit einem Linearmotor, pneumatischen Arbeitszylinder oder dgl. betätigt werden. Die beiden Endstellungen "Sammeln" oder "Nichtsammeln" des Deckscheibenträgers 64 können durch geeignete elektrische Mittel, z. B. Endschalter oder Initiator gemeldet und im Rechner gespeichert werden. The shifting claw 65 can by means of a linear guide 71 guided in the side frame 51 and z. B. with a Linear motor, pneumatic working cylinder or the like be operated. The two end positions "collecting" or "Not collecting" the cover plate carrier 64 can by suitable electrical means, e.g. B. limit switch or Initiator reported and saved in the computer.

Durch die geringe Umfangsgeschwindigkeitsdifferenz zwischen den am Zylinder 2 angebrachten Kurvenrollen 24, 34 zu den sich in gleicher Richtung des Zylinders 2 drehenden Kurvenscheiben 36, 37 ist eine lange Standzeit des Kurvengetriebes gegeben. Eine Anzahl zusätzlicher Antriebe für die Deckscheiben 62, 63 entfallen.Due to the low circumferential speed difference between the cam rollers 24 attached to the cylinder 2, 34 to those in the same direction as the cylinder 2 rotating cams 36, 37 is a long service life given the cam gear. A number of additional ones Drives for the cover plates 62, 63 are omitted.

Es ist auch möglich, den Zylinder 2 mit einer anderen Teilung zu versehen, z. B. n = 5.It is also possible to use a different cylinder 2 To provide division, z. B. n = 5.

Weiterhin kann der Steuerkurventräger 48 über das Zahnrad 53 auch von einem nichtgezeigten auf dem Wellenzapfen des Falzklappenzylinders 4 befestigten Zahnrad angetrieben werden. Furthermore, the cam carrier 48 can Gear 53 also from a not shown on the Fasten the shaft journal of the jaw cylinder 4 Gear driven.
