Abstract

In a device for superposing strips, which are formed by longitudinal cutting of at least one web printed in a web-fed rotary printing press, by means of turning bars before the inlet into a downstream folding apparatus, which device has at least three pairs, arranged one above the other, of reversible turning bars and two deflecting rollers (22, 23) laterally next to the turning bars, the material and operating expenditure is reduced by the fact that the two deflecting rollers (22, 23) can be moved individually in the vertical direction in each case by means of a drive motor (32) and two slide pieces (31a, 31b), and each deflecting roller (22, 23) can be positioned at the level of one pair of turning bars by means of an initiator (34) despite the possibility of inserting one strip, either inverted or uninverted, between two other strips. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum übereinanderführen von Strängen, die durch Längsschnitt mindestens einer in einer Rollenrotationsdruckmaschine bedruckten Bahn gebildet werden, mittels Wendestangen vor dem Einlauf in einen nachgeordneten Falzapparat.The invention relates to a device for superimposing strands, which are formed by longitudinal cutting of at least one web printed in a web-fed rotary printing press, by means of turning bars before entering a downstream folder.

Aus der DE-Offenlegungsschrift 35 01 389 ist bereits eine derartige Vorrichtung bekannt, bei der eine Reihe von in gleichmäßigen Abständen übereinanderliegende Wendestangen vorgesehen sind. Dabei ist jeder Wendestange eine Umlenkwalze zugeordnet. Sämtliche Umlenkwalzen sind seitlich neben den Wendestangen angeordnet. Hierdurch wird die Zugänglichkeit zu den Wendestangen erheblich erschwert.Such a device is already known from DE-Laid-Open Specification 35 01 389, in which a number of turning bars lying one above the other at uniform intervals are provided. Each turning bar is assigned a deflection roller. All deflection rollers are arranged on the side next to the turning bars. This makes access to the turning bars considerably more difficult.

Bei Verarbeitung von zwei Bahnen ergeben sich bei obiger Anordnung außerdem sehr lange und komplizierte Strangwege, da räumlich getrennte Sätze von Wendestangen erforderlich sind, wenn ein Strang einer Bahn zwischen zwei Stränge der anderen Bahn eingeführt werden soll.When processing two lanes, the arrangement above also results in very long and complicated strand paths, since spatially separate sets of turning rods are required if a strand of one lane is to be inserted between two strands of the other lane.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der oben genannten Art so weiter zu entwickeln, daß trotz einer Möglichkeit, einen Strang gestürzt oder ungestürzt zwischen zwei andere Stränge einzuführen, den Material- und Bedienungsaufwand verringert wird.The invention has for its object to further develop a device of the type mentioned above that, despite the possibility of inserting a strand overturned or unthreaded between two other strands, the material and operating effort is reduced.

Eine Ausführungsform der Erfindung ergibt sich aus der nachstehenden Beschreibung anhand der Zeichnung. In der Zeichnung zeigt:

Die Anordnung gemäß Fig. 1 umfaßt drei Rollenwechsler 1, die bei der dargestellten Produktion je eine Bahn 2 a, 2 b, 2 c an je eines der darüberliegenden drei Druckwerke 3 zum Bedrucken liefern.The arrangement according to FIG. 1 comprises three reel changers 1, which each deliver a web 2 a, 2 b, 2 c to one of the three printing units 3 above for printing in the production shown.

Den Druckwerken 3 folgen Schneideeinrichtungen 5 für jede Bahn, acht Wendestangen 6, 7, 8, 9, 10, 11, 12, 13, die jeweils paarweise zusammengefaßt sind, vier Doppelschwenkregulierungen 14 und ein nachgeordneter Falzapparat 15. In den Schneideeinrichtungen 5 wird jede der Bahnen 2 a, 2 b, 2 c einmal in Längsrichtung geschnitten.The printing units 3 are followed by cutting devices 5 for each web, eight turning bars 6, 7, 8, 9, 10, 11, 12, 13, which are each combined in pairs, four double-swivel controls 14 and a downstream folder 15. In the cutting devices 5, each of the Lanes 2 a, 2 b, 2 c cut once in the longitudinal direction.

In Fig. 2 sind sechs durch Längsschnitt erzeugte Stränge 16, 17, 18, 19, 20, 21 einlaufend in die Ebenen der einzelnen Paare von Wendestangen 6 bis 13 zu sehen. Aus Gründen der Deutlichkeit sind die Abstände der Paare von Wendestangen 6 bis 13 größer als erforderlich dargestellt. Jede Wendestange 6 bis 13 ist von der Bedienungsseite 26 her um 90° umsetzbar. Die ein Umsetzen erlaubende Lagerung der Wendestangen 6 bis 13 ist an sich bekannt und daher nicht dargestellt.In Fig. 2 six strands 16, 17, 18, 19, 20, 21 produced by longitudinal section are seen running into the planes of the individual pairs of turning bars 6 to 13. For reasons of clarity, the distances between the pairs of turning bars 6 to 13 are shown larger than necessary. Each turning bar 6 to 13 can be implemented from the operating side 26 by 90 °. The storage of the turning bars 6 to 13, which permits implementation, is known per se and is therefore not shown.

Der die Wendestangen 6 bis 13 aufnehmende Raum ist durch die Wand 25 der Antriebsseite und die Wand 26 der Bedienungsseite, die beide ein Bedienungsfenster 27 aufweisen, räumlich begrenzt.The space accommodating the turning bars 6 to 13 is spatially limited by the wall 25 on the drive side and the wall 26 on the operating side, both of which have an operating window 27.

Außen neben der Wand 26 sind zwei parallele Führungsschienen 28 a, 28 b montiert, die zur höhenverstellbaren Lagerung zweier Umlenkwalzen 22, 23 dienen. In Fig. 2 sind durch einen Kreis die alternativ möglichen Positionen 29 der Umlenkwalzen 22, 23 angedeutet. Die Längsachsen der Umlenkwalzen 22, 23 verlaufen parallel zu der mit dem Pfeil a gekennzeichneten Laufrichtung der Bahnen 2 a, 2 b, 2 c. Die Umlenkwalzen sind aus Gründen der Übersichtlichkeit in Fig. 1 nicht dargestellt. Vor der der Wand 26 abgewandten Seite der Führungsschienen 28 a und 28 b ist eine ortsfest gelagerte, angetriebene Zugwalze 24 vorgesehen, deren Längsachse parallel zu den Längsachsen der Umlenkwalzen 22, 23 verläuft.Outside the wall 26, two parallel guide rails 28 a, 28 b are mounted, which are used for the height-adjustable mounting of two deflecting rollers 22, 23. 2, the alternatively possible positions 29 of the deflecting rollers 22, 23 are indicated by a circle. The longitudinal axes of the deflecting rollers 22, 23 run parallel to the running direction of the tracks 2 a, 2 b, 2 c marked with the arrow a. The deflecting rollers are not shown in FIG. 1 for reasons of clarity. In front of the side of the guide rails 28 a and 28 b facing away from the wall 26, a stationary, driven pull roller 24 is provided, the longitudinal axis of which runs parallel to the longitudinal axes of the deflecting rollers 22, 23.

Die beiden Stränge 16, 17 der Bahn 2 a laufen in die die Unterseite der Wendestange 6 tangierenden Ebene ein. Der eine Strang 16 wird ungewendet unter der Wendestange 6 durchgeführt. Der andere Strang 17 wird mit Hilfe der als Winkelwendestange eingesetzten Wendestange 7 um 90° in Richtung zur Umlenkwalze 22 umgelenkt und durch das Bedienungsfenster 27 der Bedienungsseite 26 geführt. Der weitere Weg des Stranges 17 führt über die Umlenkwalze 22, die angetriebene Zugwalze 24, die die verschiedenen Zugverhältnisse der Stränge 16, 17 ausgleicht, und die Umlenkwalze 23 zur Unterseite der Wendestange 11. Die Wendestange 11 wirkt als Parallelwendestange und bringt den Strang 17 über den Strang 19. Dabei wird der Strang 17 gestürzt, also die Seite, die beim Anlauf an die Wendestange 6 oben war, liegt nunmehr unten.The two strands 16, 17 of the web 2 a run into the plane tangent to the underside of the turning bar 6. One strand 16 is carried out unturned under the turning bar 6. The other strand 17 is deflected by means of the turning bar 7 used as an angle turning bar 7 by 90 ° in the direction of the deflecting roller 22 and guided through the operating window 27 on the operating side 26. The further path of the strand 17 leads over the deflecting roller 22, the driven pull roller 24, which compensates for the different tensile conditions of the strands 16, 17, and the deflecting roller 23 to the underside of the turning bar 11. The turning bar 11 acts as a parallel turning bar and brings the strand 17 over the strand 19. The strand 17 is overturned, that is to say the side which was at the start of the turning bar 6 is now at the bottom.

Die zwei ebenfalls durch Längsschnitt erzeugten Stränge 18, 19 der Bahn 2 b laufen tangential zur Unterseite der Wendestangen 8 an. Anschließend läuft der eine Strang 18 wieder direkt, ohne eine Wendestange zu nutzen, weiter. Der andere Strang 19 wird ungestürzt über die beiden Wendestangen 8, 9, von denen die erste als Winkelwendestange und die zweite als Parallelwendestange dient, über den ersten Strang 18 mit diesem in Deckung gebracht.The two strands 18, 19 of the web 2 b likewise produced by longitudinal section run tangentially to the underside of the turning bars 8. Then one strand 18 continues to run directly without using a turning bar. The other strand 19 is brought into alignment with the two strand bars 8, 9, of which the first serves as an angle turning bar and the second as a parallel turning bar, over the first strand 18.

Die dritte Bahn 2 c läuft wie schon bei der Bahn 2 b beschrieben über die Wendestangen 12, 13. Hierbei werden in gleicher Weise die Stränge 20, 21 ungestürzt übereinander geführt.The third web 2 c runs as already described for the web 2 b over the turning bars 12, 13. Here, the strands 20, 21 are guided one above the other without rushing.

Von den nunmehr sämtlich parallel übereinander liegenden Stränge 16, 17, 18, 19, 20, 21 werden die ungewendeten Stränge über die vom Stand der Technik her bekannten Doppelschwenkregulierungen 14, um die exakte Weiterverarbeitung zu gewährleisten, dem nachgeordneten Falzapparat 15 zugeführt.Of the strands 16, 17, 18, 19, 20, 21, which are now all lying one above the other in parallel, the unturned strands are moved via the double pivoting controls 14 known from the prior art, in order to to ensure exact further processing, fed to the downstream folder 15.

Bei dem Ausführungsbeispiel nach Fig. 1 werden drei Bahnen 2 a, 2 b, 2 c verarbeitet. Es ist jedoch denkbar, eine weitere Bahn zu verarbeiten, wozu ein weiteres Paar von Wendestangen notwendig ist. Allgemein kann man sagen, daß für n Bahnen, die verarbeitet werden sollen, n+1 Wendestangenpaare übereinandergesetzt werden müssen.In the embodiment of Fig. 1, three webs 2a, 2b, 2c are processed. However, it is conceivable to process another web, for which a further pair of turning bars is necessary. In general it can be said that for n webs to be processed, n + 1 pairs of turning bars have to be placed on top of one another.

In Fig. 3 sind nochmals die Lagen der beiden bewegbaren Umlenkwalzen 22, 23, sowie der Zugwalze 24 gezeigt. Weiterhin sind die Lagen der Achsen der Wendestangen 6 bis 13 strichpunktiert angedeutet.In Fig. 3, the positions of the two movable deflecting rollers 22, 23 and the pull roller 24 are shown again. Furthermore, the positions of the axes of the turning bars 6 to 13 are indicated by dash-dotted lines.

Zusätzlich ist in der Höhe der Umlenkwalze 23 rechts außerhalb des Aufbaus, der durch die Führungsschienen 28 a, 28 b begrenzt ist, senkrecht zu den Umlenkwalzen 22, 23 liegend, eine weitere Umlenkwalze 30 angedeutet. Damit ist die Möglichkeit gegeben, den Strang 17, der gemäß Fig. 2 mit den anderen Strängen 16, 18, 19 gemischt wird, ungestürzt parallel zwischen die anderen Stränge zu führen. Hierzu wird die Wendestange 11 umgesetzt, so daß der Strang 17 durch sie entgegen der Richtung des in Fig. 2 angegebenen Pfeiles von der Wendestange 11 abläuft. Der Strang 17 wird dann mittels der Umlenkwalze 30 um etwa 180° umgelenkt, so daß er diese Umlenkwalze wieder in der Ablaufrichtung der übrigen Stränge verläßt.In addition, another deflecting roller 30 is indicated at the height of the deflecting roller 23 on the right outside the structure, which is delimited by the guide rails 28 a, 28 b, lying perpendicular to the deflecting rollers 22, 23. This makes it possible to run the strand 17, which is mixed with the other strands 16, 18, 19 according to FIG. 2, in an undeveloped manner parallel between the other strands. For this purpose, the turning bar 11 is implemented so that the strand 17 runs through it from the turning bar 11 against the direction of the arrow shown in FIG. 2. The strand 17 is then deflected by the deflecting roller 30 by about 180 °, so that it leaves this deflecting roller again in the direction of the other strands.

Durch Versetzen der Umlenkwalze 23 kann der Strang 17 auch entweder über die Wendestange 9 oder 13 den anderen Strängen zugemischt werden. Dabei wird dann dem Paar der Wendestangen 8, 9 oder 12, 13 keine Bahn zugeführt. Die Möglichkeit des Versetzens der Umlenkwalzen 22, 23 ohne eingezogene Bahnen schafft weiterhin eine gute Zugänglichkeit zu den Wendestangen 6 bis 13 durch das Bedienungsfenster 27.By displacing the deflection roller 23, the strand 17 can also be mixed with the other strands either via the turning bar 9 or 13. In this case, no web is fed to the pair of turning bars 8, 9 or 12, 13. The possibility of displacing the deflecting rollers 22, 23 without the webs being drawn in also creates good accessibility to the turning bars 6 to 13 through the operating window 27.

Als weiterer Vorteil dieser Vorrichtung erweist sich, daß die beiden Umlenkwalzen 22, 23 motorisch positionierbar sind. Die Einstellung kann also von einem Steuerpult aus vorgenommen werden.Another advantage of this device is that the two deflecting rollers 22, 23 can be positioned by a motor. The setting can therefore be made from a control panel.

Hierzu sind entlang der beiden Führungsschienen 28 a, 28 b, die als Zahnstangen ausgebildet sind, zur Halterung jeder Umlenkwalze 22, 23 zwei Gleitstücke 31 a, 31 b bewegbar angeordnet. An den beiden Gleitstücken 31 a, der Führungsschiene 28 a ist je ein Antriebsmotor 32 montiert. Weiterhin ist für jede mögliche Position 29 der Umlenkwalzen 22, 23 je ein ortsfest angebrachter Initiator 34 vorgesehen.For this purpose, two sliders 31 a, 31 b are movably arranged along the two guide rails 28 a, 28 b, which are designed as toothed racks, for holding each deflecting roller 22, 23. A drive motor 32 is mounted on each of the two sliding pieces 31 a, the guide rail 28 a. Furthermore, a fixed initiator 34 is provided for each possible position 29 of the deflecting rollers 22, 23.

Jedes Gleitstück 31 a, 31 b weist ein Führungsgehäuse 36 auf, das die Führungsschiene 28 a bzw. 28 b an drei Seiten umgreift. Vor der vierten, die Verzahnung tragenden Seite jeder Führungsschiene 28 a, 28 b ist ein Ritzel 33 angeordnet, das auf der Welle des Antriebsmotors 32 sitzt und in die Verzahnung eingreift. Jedes Gleitstück 31 a, 31 b weist weiterhin ein Lager 44 für eine Achse 35 der Umlenkwalze 22 bzw. 23 auf.Each slider 31 a, 31 b has a guide housing 36 which engages around the guide rail 28 a or 28 b on three sides. In front of the fourth, the toothing-bearing side of each guide rail 28 a, 28 b, a pinion 33 is arranged, which sits on the shaft of the drive motor 32 and engages in the toothing. Each slider 31 a, 31 b also has a bearing 44 for an axis 35 of the deflection roller 22 and 23, respectively.

In die Führungsschienen 28 a, 28 b sind mehrere, je einer vorgesehenen Einstellposition der Umlenkwalzen 22, 23 zugeordnete pyramidenförmige Kerben 37 eingearbeitet. Mit den Kerben 37 kann ein beweglicher Riegel 39 zusammenwirken. Der Riegel 39 ist fest mit einem Kolben 41 verbunden. Der Kolben ist in einem Zylinder 38 geführt. An der einen Seite des Kolbens greift eine Rückstellfeder 40 an. Vor der anderen Seite mündet eine Druckluft-Zuleitung 42. Diese Teile bilden eine Positioniereinrichtung. Am Führungsgehäuse 36 ist ferner ein Plättchen 43 montiert, das mit dem Initiator 34 zusammenwirken kann. Der Initiator 34 ist nach Art einer Lichtschranke aufgebaut, die ein Steuersignal gibt, wenn das Plättchen 43 dem Initiator gegenübergestellt wird.A plurality of pyramid-shaped notches 37, each associated with an intended setting position of the deflecting rollers 22, 23, are incorporated into the guide rails 28 a, 28 b. A movable latch 39 can interact with the notches 37. The bolt 39 is firmly connected to a piston 41. The piston is guided in a cylinder 38. A return spring 40 acts on one side of the piston. A compressed air supply line 42 opens out on the other side. These parts form a positioning device. A plate 43 is also mounted on the guide housing 36 and can cooperate with the initiator 34. The initiator 34 is constructed in the manner of a light barrier which gives a control signal when the plate 43 is juxtaposed with the initiator.

Zur Einstellung einer Umlenkwalze 22, 23 in einer bestimmten Position, wird der dieser Position zugeordnete Initiator 34 aktiviert. Der Antriebmotor 32 bewegt nun über Ritzel 33 und Zahnstange 28 die Umlenkwalze 22 bzw. 23. Erreicht diese die gewünschte Position, löst das quer zum Initiator 34 stehende Plättchen 43 in diesem ein Signal aus. Dieses Signal löst zum einen das Abschalten des Antriebmotors 32 aus. Gleichzeitig wird ein Steuerventil geöffnet und dadurch der pneumatische Zylinder 38 mit Druckluft beaufschlagt. Der Kolben 41 bewegt den Riegel 39 in Richtung der gegenüberliegenden pyramidenförmigen Kerbe 37, so daß der Riegel 39 einrastet und somit die Umlenkwalze 22 bzw. 23 fest verriegelt, wobei über die Schrägflächen der Kerbe 37 und des Riegels 39 eine genaue Positionierung des Gleitstücks 31 a bzw. 31 b und damit der Umlenkwalze 22 a bzw. 22 b erfolgt.In order to set a deflection roller 22, 23 in a specific position, the initiator 34 assigned to this position is activated. The drive motor 32 now moves the deflection roller 22 and 23 via the pinion 33 and the toothed rack 28. When the latter reaches the desired position, the plate 43 which is transverse to the initiator 34 triggers a signal in the latter. On the one hand, this signal triggers the shutdown of the drive motor 32. At the same time, a Control valve opened and thereby the pneumatic cylinder 38 is pressurized with compressed air. The piston 41 moves the bolt 39 in the direction of the opposite pyramid-shaped notch 37, so that the bolt 39 engages and thus firmly locks the deflecting roller 22 or 23, with the sloping surfaces of the notch 37 and the bolt 39 accurately positioning the slide 31 a or 31 b and thus the deflecting roller 22 a or 22 b.
