Description

Die Erfindung betrifft eine verstellbare Wendestange für eine Materialbahn entsprechend dem Oberbegriff des Patentanspruches 1.The invention relates to an adjustable turning bar for a material web according to the preamble of patent claim 1.

Die GB-A-2 256 188 beschreibt eine verschwenkbare Wendestange zum Umlenken einer Warenbahn, die mit Blasluft beaufschlagbare Blasöffnungen aufweist. Mittels eines Kolbens sind die Blasöffnungen auf eine Breite der Warenbahn anpaßbar.GB-A-2 256 188 describes a pivotable turning bar for deflecting a material web which has blowing openings which can be blown with blowing air. The blow openings can be adjusted to a width of the web by means of a piston.

Durch die DE 31 27 872 C2, die dem Oberbegriff des Anspruchs 1 entspricht, ist ein Wendestangenwagen zum Wenden einer Papierbahn mit einem auf zwei parallelen Führungsspindeln verschiebbar angeordnetem Schlittenteil bekannt, an dessen Ende L-förmig ein Querträger angeordnet ist und mit einer umlegbaren, an den Enden des Schlittenteils und Querträgers in Drehgelenken gehaltenen Wendestange. Dabei wird der Wendestange über eine Öffnung mittels eines Teleskoprohres Blasluft zugeführt, welche wiederum aus am Umfang der Wendestange angeordneten Öffnungen gegen die Papierbahn ausströmt.From DE 31 27 872 C2, which corresponds to the preamble of claim 1, a turning bar carriage for turning a paper web with a sliding part arranged displaceably on two parallel guide spindles is known, at the end of which an L-shaped cross member is arranged and with a foldable one the ends of the slide part and cross member in the pivot bar held in pivot joints. Blown air is fed to the turning bar through an opening by means of a telescopic tube, which in turn flows out of openings arranged on the circumference of the turning bar against the paper web.

Nachteilig bei dieser Anordnung zum Umlegen einer Wendestange ist es, daß die in der einen Stellung einer Wendestange zur Papierbahnführung bisher benötigten, am Umfang der Wendestange angeordneten Luftaustrittsöffnungen in einer anderen Stellung der Wendestange, in welcher die Papierbahn aus einer anderen Richtung, z. B. um 180° versetzt ankommend einläuft, teilweise nicht benötigt und somit verschlossen werden müssen, um einen Druckluftabfall zu vermeiden.A disadvantage of this arrangement for folding a turning bar is that the air outlet openings previously required in the one position of a turning bar for guiding the paper web, arranged on the circumference of the turning bar in a different position of the turning bar, in which the paper web from a different direction, for. B. arrives arriving offset by 180 °, sometimes not needed and must therefore be closed to avoid a drop in compressed air.

Der Erfindung liegt die Aufgabe zugrunde, eine verstellbare blasende Wendestange für eine Materialbahn, vorzugsweise eine Papierbahn für Druckmaschinen zu schaffen, bei welcher die zeitweise nicht benötigten, von einer Papierbahn nicht umschlungenen, in der Mantelfläche der Wendestange angeordneten Blasöffnungen verschließbar sind.The invention has for its object to provide an adjustable blowing turning bar for a web of material, preferably a paper web for printing presses, in which the blowing openings which are temporarily not required and are not wrapped around by a paper web and are arranged in the lateral surface of the turning bar can be closed.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of patent claim 1.

Durch die Erfindung werden insbesondere folgende Vorteile erzielt:
Für eine nach dem Verschwenken der Wendestangen veränderte Papierbahnführung werden die außerhalb der Umführung der Papierbahn auf der Mantelfläche der Wendestangen derzeitig nicht benötigten Luftaustrittsöffnungen allein durch das einseitige Verschwenken der Wendestange um einen Winkel von 90° selbsttätig verschlossen, so daß ein zusätzlicher Aufwand dafür entfällt. Bei einem weiteren Ausführungsbeispiel können, wie in Fig. 16 dargestellt, mit minimalen Aufwand unabhängig von der jeweiligen Stellung der Wendestange die jeweils nicht benötigten Luftaustrittsöffnungen verschlossen werden. Dies gilt auch für viertel-bahnbreite Papierbahnen.
The following advantages are achieved in particular by the invention:
For a changed paper web guide after pivoting the turning bars, the air outlet openings that are not currently required outside the bypassing of the paper web on the lateral surface of the turning bars are automatically closed solely by pivoting the turning bar on one side by an angle of 90 °, so that no additional effort is required. In a further exemplary embodiment, as shown in FIG. 16, the air outlet openings which are not required in each case can be closed with minimal effort regardless of the respective position of the turning bar. This also applies to quarter-wide paper webs.

Die Erfindung wird nachfolgend anhand von mehreren Ausführungsbeispielen näher erläutert.The invention is explained in more detail below on the basis of several exemplary embodiments.

Die in Fig. 1 dargestellten, einem angedeuteten Seitengestell 9 zugewandten Luftöffnungen sind mit 11, 12, 13, 14 bezeichnet und weitere Luftöffnungen 16, 17, 18, 19 sind in dem Rohr 2 gezeigt, die einem angedeuteten Seitengestell 21 zugewandt sind. Die Luftöffnungen 11 bis 14 und 16 bis 19 können als Bohrungen mit jeweils einem Durchmesser a ausgeführt sein. In dem Rohr 2 ist eine in Richtung der Rotationsachse 8 mit gleichem Profil um einen Betrag a verschiebbarer topfförmiger Schieber 22 mit gleichem Profil angeordnet. Dabei ist der Außendurchmesser des Schiebers 22 so bemessen, daß der Schieber 22 mit seiner äußeren Mantelfläche 20 am Innenmantel 25 des Rohres 2 saugend gleitet, d. h. daß bei Betätigung des Schiebers 22 im Rohr 2 ein geringfügiger Reibungswiderstand zu überwinden ist. Der Schieber 22 weist an seinem ersten Ende 23 einen Boden 24 auf, der an dem ersten Endstück 6 anliegt. Ein zweites offenes Ende 26 des Schiebers 22 stößt mit seiner ringförmigen Stirnseite gegen die äußere Windung einer Druckfeder 27. Das zweite Ende der Druckfeder 27 liegt an dem zweiten Endstück 7 an. Das zweite Endstück 7 ist mit seinem Ende 28 dem Innen- und Außendurchmesser des Rohres 2 angepaßt und besitzt in der Nähe der Rotationsachse 8 eine axiale Luftzuführung 29, die in eine wendestangenferne Richtung weist und als Bohrung ausgeführt sein kann. Ein zweites Ende 31 des Endstückes 7 wird form- und kraftschlüssig von der Halterung 32 umfaßt, die wiederum form- und kraftschlüssig über ein Drehgelenk 33 mit einem auf einer Tragspindel 34 verschiebbaren Wendestangenhalter 36 verbunden ist (Fig. 1 und 3). Auf der Wendestange 1 in Fig. 3 wurden der besseren Übersicht halber keine Luftöffnungen dargestellt. Die Luftzuführung 29 ist über einen Schlauch 37 mit einer nichtdargestellten Druckluftquelle verbunden.According to the illustration in FIG. 1, a longitudinal section through a turning bar according to the invention, generally designated 1, is shown in a plan view of a turning bar frame before an entry into a folder of a web-fed rotary printing press. The turning bar 1 consists of a tube 2, which is closed at its two ends 3, 4 with non-positively and positively arranged end pieces 6, 7. The tube 2 has a large number of air openings in its outer surface, which extend from a “rotation axis” 8 in the radial direction. The air openings shown in FIG. 1, which face an indicated side frame 9, are designated 11, 12, 13, 14 and further air openings 16, 17, 18, 19 are shown in the tube 2, which face an indicated side frame 21. The air openings 11 to 14 and 16 to 19 can be designed as bores each with a diameter a. Arranged in the tube 2 is a cup-shaped slide 22 with the same profile, which can be displaced in the direction of the axis of rotation 8 with the same profile by an amount a. It is the outer diameter of the slider 22 is dimensioned such that the slider 22 slides with its outer jacket surface 20 on the inner jacket 25 of the tube 2, that is to say that a slight frictional resistance must be overcome when the slide 22 is actuated in the tube 2. The slider 22 has at its first end 23 a bottom 24 which bears on the first end piece 6. A second open end 26 of the slide 22 abuts with its annular end face against the outer turn of a compression spring 27. The second end of the compression spring 27 abuts the second end piece 7. The second end piece 7 is adapted with its end 28 to the inner and outer diameter of the tube 2 and has in the vicinity of the axis of rotation 8 an axial air supply 29 which points in a direction remote from the turning rod and can be designed as a bore. A second end 31 of the end piece 7 is positively and non-positively encompassed by the holder 32, which in turn is positively and non-positively connected via a swivel 33 to a turning bar holder 36 which can be displaced on a supporting spindle 34 (FIGS. 1 and 3). For the sake of clarity, no air openings have been shown on the turning bar 1 in FIG. 3. The air supply 29 is connected via a hose 37 to a compressed air source, not shown.

Das erste Endstück 6 ist mit seinem ersten Ende 38 dem Innen- und Außendurchmesser des Rohres 2 angepaßt und sein zweites, in wendestangenferne Richtung weisendes Ende 39 ist kraft- und formschlüssig über ein Drehgelenk 41 mit einem im Profil etwa T-förmig ausgebildeten Wendestangenhalter 42 verbunden, der wiederum auf einer Tragspindel 43 verschiebbar ist. Der Wendestangenhalter 42 weist auf der dem Seitengestell 21 zugewandten Seite des eines dem Drehgelenk 41 zugewandten Teiles 44 des Wendestangenhalters 42 einen auf diesem kraft- und formschlüssig angeordneten Steuernocken 46 auf, welcher gegen einen Bolzen 47 wirkt, der konzentrisch zur Rotationsachse 8 kraft- und formschlüssig am Boden 24 der Hülse 22 angeordnet ist und seitlich neben dem Drehgelenk 41 durch eine Bohrung im ersten Ende 38 des Endstückes 6 ragt. Das dem Bolzen 47 zugewandte Ende des Steuernockens 46 kann um 45° zu einer achsparallelen Waagerechten 8 abgeschrägt sein, so daß erst beim Schwenken der Wendestange 1 um einen Drehwinkel α1 von 45° zwischen der Rotationsachse 8 und dem Seitengestell 21 um das Drehgelenk 41 ein axiales Verschieben des Schiebers 22 gegen die Kraft der Druckfeder 27 erfolgt (Fig. 2).The first end piece 6 is adapted with its first end 38 to the inside and outside diameter of the tube 2 and its second end 39 pointing in the direction remote from the turning rod is non-positively and positively via a swivel joint 41 connected to an approximately T-shaped turning bar holder 42, which in turn is displaceable on a support spindle 43. The turning bar holder 42 has, on the side of the side frame 21 of the part 44 of the turning bar holder 42 facing the swivel joint 41, a control cam 46 arranged thereon in a non-positive and positive manner, which acts against a bolt 47 which is concentric with the axis of rotation 8 non-positive and positive is arranged on the bottom 24 of the sleeve 22 and projects laterally next to the swivel joint 41 through a bore in the first end 38 of the end piece 6. The end of the control cam 46 facing the bolt 47 can be chamfered by 45 ° to an axially parallel horizontal 8, so that only when the turning bar 1 is pivoted by an angle of rotation α 1 of 45 ° between the axis of rotation 8 and the side frame 21 about the swivel 41 Axial displacement of the slide 22 takes place against the force of the compression spring 27 (Fig. 2).

Die Hülse 22 weist eine Anzahl von Luftöffnungen auf, die auf der dem Seitengestell 9 zugewandten Seite der Wendestange 1 mit 48, 49, 50, 51 bezeichnet sind und auf der dem Seitengestell 21 zugewandten Seite der Wendestange 1 mit 54, 55, 56, 57 bezeichnet sind. Die Anzahl der im Rohr 2 angeordneten Luftöffnungen 11 bis 14 und 16 bis 19 entspricht der Anzahl der in der Hülse 22 angeordneten Luftöffnungen 48 bis 51 und 54 bis 57. Die Luftöffnungen 48 bis 51 und 54 bis 57 können ebenfalls kreisrund sein und einen Durchmesser a aufweisen. Im Falle einer Winkelstellung I oder II der Wendestange 1 (Fig. 1 und 4) liegt der Boden 24 der Hülse 22 an dem ersten Ende des Endstückes 6 innen an. Dies entspricht in Stellung I einem Winkel α2 von 45° zu der Rotationsachse 8 und Seitengestell 9. Auch bei Stellung II der Wendestange 1 nach Fig. 2 in Richtung Rotationsachse 8 liegt der Boden 24 der Hülse 22 am ersten Ende des Endstückes 6 innen an. Dabei sind die dem Seitengestell 9 zugewandten Luftöffnungen 11, 12, 13, 14 des Rohres 2 deckungsgleich mit den Luftöffnungen 48, 49, 50, 51 der Hülse 22 (Fig. 1), so daß die durch den Schlauch 37 und die Luftzuführung 29 ins Innere der Wendestange 1 zugeführte Luft durch die genannten Luftöffnungen entweichen kann und eine nichtdargestellte Papierbahn um die mit Druckluft beaufschlagten Luftöffnungen 11, 48; 12, 49; 13, 50 sowie 14, 51 der Wendestange 1 herumgeführt wird. Die auf der Seite des Seitengestells 21 angeordneten, nicht von einer Papierbahn umschlungenen Luftöffnungen 16 bis 19 sowie 54 und 57 der Wendestange 1 sind verschlossen, so daß keine Druckluft entweichen kann. In der Stellung III (Fig. 2 und 4) wird die Wendestange 1 um das Drehgelenk 41 in einem Winkel α1 und α2 von 90° verschwenkt. Durch die Wirkung des Nockens 46 auf den Bolzen 47 wird der Schieber 22 um einen Betrag a in Richtung Wendestangenhalter 36 verschoben, so daß die bei Stellung I und II der Wendestange 1 genannten Luftöffnungen geschlossen sind. Nunmehr sind die Luftöffnungen 54, 16; 55, 17; 56, 18 und 57, 19 geöffnet, so daß eine nichtdargestellte Papierbahn um die vorgenannten Luftöffnungen der Wendestange 1 geführt und somit ein Luftpolster zwischen Papierbahn und Wendestange 1 erzeugt wird. Der nicht von der Papierbahn umschlungene, in Richtung Seitengestell 9 weisende Teil der Wendestange 1 läßt keine Druckluft durch die nunmehr gegeneinander versetzten Luftöffnungen 48, 11; 49, 12 durch. Dies kommt dadurch zustande, daß die Luftöffnungen 48 bis 51 der Hülse 22 auf der dem Seitengestell 9 zugewandten Seite der Wendestange 1 nicht mit den Luftöffnungen 54 bis 57 der Hülse 22 auf der dem Seitengestell 21 zugewandten Seite der Wendestange 1 fluchten, sondern um einen Betrag a versetzt sind, so daß nur die Luftöffnungen 48, 11; 49, 12; 50, 12; 51, 14 oder die Luftöffnungen 54, 16; 55, 17; 56, 18; 57, 19 geöffnet sind. Die Luftöffnungen 11 bis 14 sowie 16 bis 19 des Rohres 2 fluchten jedoch jeweils miteinander. In Fig. 4 wird schematisch ein Umlegevorgang einer Wendestange 1 gezeigt. Zur Vereinfachung der Darstellung des Umlegevorganges wurde hierbei auf die Darstellung der Längsführungen und Antriebe für die Wendestangen verzichtet. Fig. 5 zeigt die Anordnung dieser und einer weiteren Wendestange aus einer Seitenansicht. Die Wendestange 1 ist mit ihren Wendestangenhaltern 42, 36 in der Lage III dargestellt, d. h. die nicht gezeigten Luftaustrittsöffnungen sind in Richtung Seitengestell 21 geöffnet, so daß z. B. eine nichtdargestellte halbbreite Papierbahn aus Richtung Tragspindel 43 an der oberen, dem Seitengestell 9 nahen Seite über eine im Winkel von 45° zu den Seitengestellen 9, 21 angeordnete Wendestange 58 um 90° in ihrer Richtung geändert, anschließend in Richtung Seitengestell 21 geführt und über die Wendestange 1 um 90° in ihrer Richtung geändert und auf der unteren, dem Seitengestell 21 nahen Seite in Richtung Tragspindel 34 aus dem Wendestangengestell herausgeführt wird. (Wendung einer halben Bahn von Seitengestell 9 nach Seitengestell 21). Es versteht sich, daß bei der Wendestange 58 die in Richtung Seitengestell 9 weisenden Luftöffnungen geöffnet sind. Die Wendestangenhalter 42, 36 der Wendestange 1 sind dabei in einer unteren Ebene verschiebbar auf Tragspindeln 43, 34 geführt und Wendestangenhalter 59, 61 der Wendestange 58 sind dabei in einer zweiten oberen Ebene auf Tragspindeln 62, 63 geführt (Fig. 5). Sämtliche Wendestangenhalter 36, 42; 59, 61 weisen eine separate Gewindebohrung 64, 66, 67, 68 auf, jeweils zur Aufnahme einer Gewindespindel 71, 72, 73, 74, welche wiederum durch einen Antrieb angetrieben wird, der in Fig. 6 dargestellt ist. Die Tragspindeln 43, 62 sind jeweils seitengestellfest gelagert. Es soll nachfolgend nur die Lageveränderung der Wendestange 1 beschrieben werden. Durch die Abwärtsbewegung des einen Wendestangenhalters 42 der Wendestange 1 auf der Tragspindel 43 sowie die Aufwärtsbewegung des anderen Wendestangenhalters 36 auf der Tragspindel 34 wird die Wendestange 1 gestreckt und kommt in die gestrichelt dargestellte waagerechte Stellung II. Dabei wird die in den Seitengestellen 9, 21 beweglich gelagerte Tragspindel 34 in die gestrichelt dargestellte Lage gebracht. Durch weiteres Verschieben der Wendestangenhalter 42, 36 in den bereits angegebenen Richtungen nimmt die Wendestange 1 nunmehr die Stellung I ein. Dabei sind die dem Seitengestell 9 zugewandten Luftöffnungen geöffnet und die dem Seitengestell 21 zugewandten Luftöffnungen geschlossen.The sleeve 22 has a number of air openings which are denoted by 48, 49, 50, 51 on the side of the turning bar 1 facing the side frame 9 and on the side of the turning bar 1 facing the side frame 21 by 54, 55, 56, 57 are designated. The number of air openings 11 to 14 and 16 to 19 arranged in tube 2 corresponds to the number of air openings 48 to 51 and 54 to 57 arranged in sleeve 22. Air openings 48 to 51 and 54 to 57 can also be circular and have a diameter a. In the case of an angular position I or II of the turning bar 1 (FIGS. 1 and 4), the bottom 24 of the sleeve 22 bears against the inside of the first end of the end piece 6. In position I, this corresponds to an angle α 2 of 45 ° to the axis of rotation 8 and side frame 9. Also in position II of the turning bar 1 according to FIG. 2 in the direction of the axis of rotation 8, the bottom 24 of the sleeve 22 lies against the inside of the first end of the end piece 6 . The side openings 9 facing air openings 11, 12, 13, 14 of the tube 2 are congruent with the air openings 48, 49, 50, 51 of the sleeve 22 (Fig. 1), so that the through the hose 37 and the air supply 29 ins Air supplied inside the turning bar 1 can escape through said air openings and a paper web (not shown) around the air openings 11, 48; 12, 49; 13, 50 and 14, 51 of the turning bar 1 is guided around. The arranged on the side of the side frame 21, not wrapped by a paper web air openings 16 to 19 and 54 and 57 of the turning bar 1 are closed, so that no compressed air can escape. In position III (Fig. 2 and 4), the turning bar 1 is pivoted about the pivot 41 at an angle α 1 and α 2 of 90 °. Due to the action of the cam 46 on the bolt 47, the slide 22 is displaced by an amount a in the direction of the turning bar holder 36, so that the air openings mentioned in positions I and II of the turning bar 1 are closed. Now are the air openings 54, 16; 55, 17; 56, 18 and 57, 19 opened so that a paper web, not shown, is guided around the aforementioned air openings of the turning bar 1 and thus an air cushion is generated between the paper web and turning bar 1. The part of the turning bar 1 which is not wrapped around by the paper web and points in the direction of the side frame 9 does not allow compressed air through the air openings 48, 11; 49, 12 through. This is due to the fact that the air openings 48 to 51 of the sleeve 22 on the side of the turning bar 1 facing the side frame 9 do not align with the air openings 54 to 57 of the sleeve 22 on the side of the turning bar 1 facing the side frame 21, but by an amount a are offset so that only the air openings 48, 11; 49, 12; 50, 12; 51, 14 or the air openings 54, 16; 55, 17; 56, 18; 57, 19 are open. However, the air openings 11 to 14 and 16 to 19 of the tube 2 are aligned with one another. In Fig. 4 a folding process of a turning bar 1 is shown schematically. In order to simplify the representation of the folding process, the longitudinal guides and drives for the turning bars have been omitted. Fig. 5 shows the arrangement of this and a further turning bar from a side view. The turning bar 1 is shown with its turning bar holders 42, 36 in position III, ie the air outlet openings, not shown, are opened in the direction of the side frame 21, so that, for. B. a half-width paper web, not shown, from the direction Carrier spindle 43 on the upper side near the side frame 9 is changed by 90 ° in its direction via a turning bar 58 arranged at an angle of 45 ° to the side frames 9, 21, then guided in the direction of side frame 21 and over the turning bar 1 by 90 ° in changed their direction and on the lower side near the side frame 21 in the direction of the support spindle 34 out of the turning bar frame. (Turn half a lane from side frame 9 to side frame 21). It goes without saying that in the turning bar 58 the air openings pointing in the direction of the side frame 9 are open. The turning bar holders 42, 36 of the turning bar 1 are slidably guided in a lower plane on support spindles 43, 34 and turning bar holders 59, 61 of the turning bar 58 are guided in a second upper level on support spindles 62, 63 (FIG. 5). All turning bar holder 36, 42; 59, 61 have a separate threaded bore 64, 66, 67, 68, each for receiving a threaded spindle 71, 72, 73, 74, which in turn is driven by a drive which is shown in FIG. 6. The support spindles 43, 62 are each fixed to the side frame. Only the change in position of the turning bar 1 will be described below. Due to the downward movement of the one turning bar holder 42 of the turning bar 1 on the supporting spindle 43 and the upward movement of the other turning bar holder 36 on the supporting spindle 34, the turning bar 1 is stretched and comes into the horizontal line shown in dashed lines Position II. The support spindle 34 movably mounted in the side frames 9, 21 is brought into the position shown in dashed lines. By further shifting the turning bar holder 42, 36 in the directions already indicated, the turning bar 1 now assumes the position I. The air openings facing the side frame 9 are opened and the air openings facing the side frame 21 are closed.

Die Fig. 6 und 7 zeigen einen Antrieb der verschiebbaren Wendestangenhalterung 36 der Wendestange 1 auf der Tragspindel 34. Die Tragspindeln 34, 63 sind an ihren Enden in Gleitsteinen gelagert, die wiederum in seitengestellfesten Längsführungen verschiebbar sind. Dies ist in Fig. 6 am Beispiel der Tragspindel 34 dargestellt, welche mit ihrem dem Seitengestell 21 zugewandten Ende in einem Gleitstein 76 gelagert ist, der in einer an der Innenseite des Seitengestells 21 formschlüssig angeordneten Längsführung 77 abgebunden verschiebbar ist. An einer Seitenwand der Längsführung 77 ist jeweils eine Zahnstange 78 befestigt, welche sich über die gesamte Länge der Längsführung 77 parallel zu dieser erstreckt. Auf der Tragspindel 34 ist formschlüssig ein Zahnrad 79 aufgebracht, welches mit der Zahnstange 78 in Eingriff steht.6 and 7 show a drive of the displaceable turning bar holder 36 of the turning bar 1 on the supporting spindle 34. The supporting spindles 34, 63 are mounted at their ends in sliding blocks, which in turn are displaceable in longitudinal guides fixed in the side frame. This is shown in FIG. 6 using the example of the support spindle 34, which is mounted with its end facing the side frame 21 in a sliding block 76 which is slidably displaceable in a longitudinal guide 77 arranged in a form-fitting manner on the inside of the side frame 21. A toothed rack 78 is attached to a side wall of the longitudinal guide 77 and extends parallel to the entire length of the longitudinal guide 77. On the support spindle 34, a gear 79 is positively applied, which meshes with the rack 78.

Die Gewindespindel 71 ist mit der Gewindebohrung 68 des Wendestangenhalters 36 in Eingriff. Das dem Seitengestell 21 zugewandte Ende der Gewindespindel 71 ragt durch einen nicht dargestellten Längsschlitz durch das Seitengestell 21 hindurch und trägt eine Zahnriemenscheibe 81. Über ein einen Achsversatz ausgleichendes Zahnriemengetriebe 82 ist die Zahnriemenscheibe 81 mit einem Elektromotor 83 über Zahnriemen 84, 86 verbunden.The threaded spindle 71 is in engagement with the threaded bore 68 of the turning bar holder 36. The end of the threaded spindle facing the side frame 21 71 protrudes through a longitudinal slot (not shown) through the side frame 21 and carries a toothed belt pulley 81. The toothed belt pulley 81 is connected to an electric motor 83 via toothed belts 84, 86 via a toothed belt transmission 82 compensating for an axial offset.

Der Tragspindel 63 sowie der Gewindespindel 74 ist an ihren dem Seitengestell 21 zugewandten Enden ein gleicher Antrieb zugeordnet, wie in Fig. 6 gezeigt. Die dem Seitengestell 9 zugewandten Enden der Tragspindel 34 und Gewindespindel 71 bzw. der Tragspindel 63 und Gewindespindel 74 sind jeweils in nicht dargestellten Längsführungen mit darin verschiebbaren Gleitsteinen gelagert.The support spindle 63 and the threaded spindle 74 are assigned an identical drive at their ends facing the side frame 21, as shown in FIG. 6. The ends of the support spindle 34 and threaded spindle 71 or the support spindle 63 and threaded spindle 74 facing the side frame 9 are each mounted in longitudinal guides (not shown) with sliding blocks which can be displaced therein.

Die Enden der Tragspindeln 43, 62 sowie die Enden der Gewindespindeln 72, 73 sind ortsfest jeweils in den Seitengestellen 9, 21 gelagert. Die dem Seitengestell 21 zugewandten Enden der Gewindespindeln 72, 73 sind mit einem Antrieb, z. B. Elektromotor, versehen.The ends of the support spindles 43, 62 and the ends of the threaded spindles 72, 73 are each fixed in place in the side frames 9, 21. The ends of the threaded spindles 72, 73 facing the side frame 21 are provided with a drive, e.g. B. electric motor.

Soll nun z. B. die Wendestange 1 entsprechend der Darstellung nach Fig. 4 von der Stellung III über die Stellung II nach Stellung I umgelegt werden, d. h. um 90° gegenüber ihrer ursprünglichen Stellung verdreht werden, so werden die Gewindespindeln 71, 72 über die zugeordneten Getriebe (Getriebe 82 ist dargestellt) bzw. Elektromotoren (ortsfester Elektromotor 83 ist dargestellt) in so einer Drehrichtung bewegt, daß der Wendestangenhalter 42 auf der Tragspindel 43 in Richtung Seitengestell 21 verfährt und der Wendestangenhalter 36 auf der Tragspindel 34 in Richtung Seitengestell 9 verfährt, bis die Stellung I der Wendestange 1 nach Fig. 4 erreicht ist. Dabei beschreibt der Wendestangenhalter 36 eine gestrichelt gezeichnete halbkreisförmige Kurve 87. Die mittels Zahnrädern 79 in Zahnstangen 78 an beiden Enden geführten Tragspindeln 34, 63 werden während des Bewegens der Tragspindeln 34, 63 jeweils synchron verfahren.Should now z. B. from the position III over the position II to position I, that is to say rotated by 90 ° with respect to their original position, the threaded spindles 71, 72 via the assigned gears (gears 82 is shown) or electric motors (stationary electric motor 83 is shown) moved in such a direction of rotation that the turning bar holder 42 moves on the supporting spindle 43 in the direction of the side frame 21 and the turning bar holder 36 moves on the supporting spindle 34 in the direction of the side frame 9 until the position I of the turning bar 1 according to FIG. 4 is reached. Here, the turning bar holder 36 describes a dashed semicircular curve 87. The support spindles 34, 63 guided at both ends by means of gear wheels 79 in racks 78 are each moved synchronously during the movement of the support spindles 34, 63.

Entsprechend den Darstellungen in Fig. 8 bis Fig. 13 wird eine Wendestange gezeigt, die der Wendestange 58 in Fig. 4 entspricht, welche über einen auf der Tragspindel 62 verschiebbaren und dem einen Ende mit einem Drehgelenk 41 versehenem Wendestangenhalter 59 ausgestattet ist und am anderen Ende über eine Halterung 32 und ein Drehgelenk 33 mit einem auf der Tragspindel 63 verschiebbaren Wendestangenhalter 61 verbunden ist (nicht dargestellt). Die Wendestange 58 ist ebenso in ihrer Lage veränderbar, wie dies bei der Wendestange 1 bereits beschrieben worden ist. Die Wendestange 58 ist entsprechend den Darstellungen in den Fig. 8 bis 10 in einer Stellung IV dargestellt, welche in einem Winkel α1 von 45° zu einer Waagerechten oder Stellung II verläuft. Dabei weist der ebenfalls T-förmig ausgebildete Wendestangenhalter 59 auf der dem Drehgelenk 41 zugewandten Seite des Profilteiles 44 beidseitig jeweils einen insgesamt mit 88 und 89 bezeichneten Steuernocken auf. Der Steuernocken 88 befindet sich auf der dem Seitengestell 21 zugewandten Seite des Wendestangenhalters 59 und ist in den Fig. 14 und 15 einzeln und vergrößert dargestellt. Der Steuernocken 89 befindet sich diametral gegenüber dem Steuernocken 88. Beide Steuernocken 88, 89 sind parallel zueinander und rechtwinklig zu einer Rotationsachse 92 der Tragspindel 62 auf dem Wendestangenhalter 59 verschiebbar angeordnet. Dazu ist in dem Steuernocken 88, 89 ein Langloch 93 vorgesehen, durch welches eine im Wendestangenhalter 59 befestigbare Schraube 91 greift. Der Steuernocken 88, 89 weist drei kurvenförmige, parallel zueinander verlaufende Steuerebenen 94, 95, 96 auf, die sich jeweils in ihrem Abstand um einen Differenzbetrag a, z. B. 5 mm, voneinander unterscheiden, z. B. in ihrer Hubhöhe. Die Wendestange 58 weist ebenfalls ein Rohr 2 auf, welches dem in Fig. 1 gezeigten Rohr 2 gleicht, welches die den dem Seitengestell 9 zugewandten Luftöffnungen 11 bis 14 und die dem Seitengestell 21 zugewandten Luftöffnungen 16 bis 19 aufweist. Im Rohr 2 befindet sich ein topfförmiger Schieber 98, dessen Luftöffnungen 101, 102, 103, 104 schlitzförmig mit einer Länge von 2a ausgeführt sind und die jeweils mit den dem Seitengestell 9 zugewandten Luftöffnungen 11, 12, 13, 14 korrespondieren. Weitere in dem Schieber 98 angeordnete schlitzförmige Luftöffnungen 106, 107, 108, 109 alt der Länge von 2a korrespondieren mit den dem Seitengestell 21 zugewandten Luftöffnungen 16, 17, 18, 19 des Rohres.According to the representations in FIGS. 8 to 13, a turning bar is shown which corresponds to the turning bar 58 in FIG. 4, which is equipped with a turning bar holder 59 which is displaceable on the supporting spindle 62 and has a swivel joint 41 at one end and the other End is connected via a bracket 32 and a pivot 33 to a turning bar holder 61 which is displaceable on the supporting spindle 63 (not shown). The position of the turning bar 58 can also be changed, as has already been described for the turning bar 1. The turning bar 58 is shown in accordance with the illustrations in FIGS. 8 to 10 in a position IV, which extends at an angle α 1 of 45 ° to a horizontal or position II. The turning bar holder 59, which is likewise T-shaped, has on both sides on the side of the profile part 44 facing the swivel joint 41 each have a total of 88 and 89 control cams. The control cam 88 is located on the side of the turning bar holder 59 facing the side frame 21 and is shown individually and enlarged in FIGS. 14 and 15. The control cam 89 is located diametrically opposite the control cam 88. Both control cams 88, 89 are arranged parallel to one another and can be displaced on the turning bar holder 59 at right angles to an axis of rotation 92 of the support spindle 62. For this purpose, an elongated hole 93 is provided in the control cam 88, 89, through which a screw 91 which can be fastened in the turning bar holder 59 engages. The control cam 88, 89 has three curved control planes 94, 95, 96 running parallel to one another, each of which is spaced apart by a difference a, z. B. 5 mm, differ from each other, e.g. B. in their lifting height. The turning bar 58 also has a tube 2, which is similar to the tube 2 shown in FIG. 1, which has the air openings 11 to 14 facing the side frame 9 and the air openings 16 to 19 facing the side frame 21. In the tube 2 there is a cup-shaped slide 98, the air openings 101, 102, 103, 104 of which are slit-shaped with a length of 2a and which each correspond to the air openings 11, 12, 13, 14 facing the side frame 9. Further slit-shaped air openings 106, 107, 108, 109 old in the slide 98, the length of 2a correspond to the air openings 16, 17, 18, 19 of the tube facing the side frame 21.

Der Durchmesser einer im Rohr 2 befindlichen kreisrunden Luftöffnung beträgt maximal a (etwa 5 mm), besser etwas weniger, z. B. a - x, wobei x einen Sicherheitsbetrag beinhaltet zum Abdichten der im Rohr 2 und in dem Schieber 98 befindlichen genannten Luftöffnungen zueinander. Der Betrag x kann z. B. bei 0,2 mm liegen. Der topfförmige Schieber 98 grenzt mit seinem Boden 111 nach Fig. 8 an einen in axialer Richtung durch ein Endstück 112 verschiebbar geführten Bolzen 113, 114, der mit seinem abgerundeten zweiten Ende 116, 117 jeweils wahlweise gegen eine der drei Steuerebenen 94, 95, 96 des Steuernockens 88, 89 wirkt und den Schieber 98 gegen die Kraft einer Druckfeder 27 in Richtung zweites Endstück der Wendestange 58 bewegt. Es ist auch möglich, die Luftöffnungen 101 bis 104 und 106 bis 109 kreisrund auszuführen mit einem Durchmesser von 2a.The diameter of a circular air opening in the tube 2 is at most a (about 5 mm), better a little less, e.g. B. a - x, where x includes a safety amount for sealing the air openings mentioned in the tube 2 and in the slide 98 to one another. The amount x can e.g. B. 0.2 mm. The pot-shaped slide 98 borders with its base 111 according to FIG. 8 on a bolt 113, 114 which is displaceable in the axial direction by an end piece 112 and which, with its rounded second end 116, 117, each selectively against one of the three control planes 94, 95, 96 of the control cam 88, 89 acts and moves the slide 98 against the force of a compression spring 27 in the direction of the second end piece of the turning bar 58. It is also possible to make the air openings 101 to 104 and 106 to 109 circular with a diameter of 2a.

In Fig. 8 ist gezeigt, daß der Boden 111 an dem ersten Ende 116 des kürzeren Bolzens 113 anliegt und das zweite Ende 116 mit der am tiefsten gelegenen Steuerebene 94 des Steuernockens 88 kraftschlüssig in Verbindung steht, so daß die Luftöffnungen 11, 101, sowie 12, 102 zueinander geöffnet sind, so daß eine viertel-bahnbreite Papierbahn 118 um diese Stelle der Wendestange 58 gewendet werden kann.In Fig. 8 it is shown that the bottom 111 abuts the first end 116 of the shorter pin 113 and the second end 116 is non-positively connected to the lowest control level 94 of the control cam 88, so that the air openings 11, 101 and 12, 102 are open to each other so that a quarter-web-wide paper web 118 can be turned around this point of the turning bar 58.

In Fig. 9 ist gezeigt, wie das zweite Ende 116 des Bolzens 113 mit der mittleren Steuerebene 95 des Steuernockens 88 in Verbindung steht, so daß die in Fig. 8 genannten Luftöffnungen 11, 101; 12, 102 sowie weiterhin die Luftöffnungen 13, 103 und 14, 104 zueinander geöffnet sind, indem der Bolzen 113 den Schieber 98 um einen Betrag a in axialer Richtung verschoben hat, so daß eine halb-bahnbreite Papierbahn 119 um diese Stelle der Wendestange 58 gewendet werden kann.In Fig. 9 it is shown how the second end 116 of the pin 113 is connected to the central control plane 95 of the control cam 88, so that the air openings 11, 101 mentioned in FIG. 8; 12, 102 and also the air openings 13, 103 and 14, 104 are open to one another by the bolt 113 having moved the slider 98 by an amount a in the axial direction, so that a half-web-wide paper web 119 turns around this point of the turning bar 58 can be.

Schließlich ist in Fig. 10 gezeigt, wie das zweite Ende 116 des Bolzens 113 mit der obersten Steuerebene 96 in Verbindung steht, so daß nur die Luftöffnungen 13, 103 sowie 14, 104 zueinander geöffnet sind, so daß eine viertel-bahnbreite Papierbahn 118 an dieser Stelle der Wendestange 58 gewendet werden kann (Fig. 14, 15). Dabei beträgt die zurückgelegte Hublänge des Bolzens 113 gleich 2a. Die Auswahl der Steuerebene 94, 95, 96 ist durch das Lösen der Schraube 91 und Verschieben des Steuernockens 88 im Bereich des Langloches 93 möglich. Die Abstände e zwischen den Mittellinien zweier lochförmiger in dem Rohr 2 angeordneter Luftöffnungen 13, 14 ist gleich dem Abstand zweier schlitzartiger, auf dem Schieber 98 angeordneter Luftöffnungen 103, 104. Der Abstand zwischen den zwei von der Wendestangenmitte aus (jeweils strichpunktiert) jeweils benachbart angeordneter, schlitzförmiger Luftöffnungen 107 - 108 sowie 102 - 103 ist gegenüber den anderen Abständen der jeweils benachbart angeordneten, schlitzförmigen Luftöffnungen 106 - 107 sowie 101 - 102 jeweils um einen Betrag a kürzer.Finally, FIG. 10 shows how the second end 116 of the pin 113 is connected to the uppermost control plane 96, so that only the air openings 13, 103 and 14, 104 are open to one another, so that a paper web 118 which is a quarter of the width wide is on this point of the turning bar 58 can be turned (Fig. 14, 15). The stroke length of the bolt 113 is equal to 2a. The control level 94, 95, 96 can be selected by loosening the screw 91 and displacing the control cam 88 in the region of the elongated hole 93. The distances e between the center lines of two hole-shaped air openings 13, 14 arranged in the tube 2 are equal to the distance between two slot-like air openings 103, 104 arranged on the slide 98. The distance between the two from the center of the turning bar (each with a dash-dot line) is arranged adjacent to one another , slot-shaped air openings 107-108 and 102-103 is shorter in each case by an amount a compared to the other distances between the slot-shaped air openings 106-107 and 101-102 which are arranged adjacent to each other.

Beim Verändern der Stellung der Wendestange 58 um einen Winkel α2 von 45° zu einer waagerechten oder gestreckten Stellung II entsprechend den Darstellungen nach Fig. 11 bis 13 kommt nunmehr der längere Bolzen 114 mit seinem zweiten Ende 117 in Eingriff mit einer der Steuerebenen 94, 95, 96 des Steuernockens 87, so daß der Schieber 98 um einen Betrag von 3a (Fig. 11), 4a (Fig. 12) oder 5a (Fig. 13) gegen die Kraft der Feder 27 verschoben wird, so daß auf der dem Seitengestell 21 zugewandten Seite 58 jeweils links oder rechts um die Wendestange 58 eine viertel-bahnbreite Papierbahn 118 oder insgesamt eine halb-bahnbreite Papierbahn 119 herumgeführt werden kann, wobei zwischen der Papierbahn 118 oder 119 und der Wendestange 58 Luft ausströmt, während die nichtgenannten Luftöffnungen geschlossen sind. Im Einzelnen sind bei der Wendestange 58 nach Fig. 11 bis 13 folgende Luftöffnungen zueinander geöffnet: in Fig. 11 die Luftöffnungen 16, 106; 17, 107 zum Umführen einer viertel-bahnbreiten Papierbahn 118 auf der linken Seite der Wendestange 58; in Fig. 12 zusätzlich zu den in Fig. 11 genannten Luftöffnungen noch die Luftöffnungen 18, 108 und 19, 109 zum Umführen einer halb-bahnbreiten Papierbahn 119 auf der gesamten Breite der dem Seitengestell 21 zugewandten Seite der Wendestange 58; in Fig. 13 nur die in Fig. 12 letztgenannten Luftöffnungen 18, 108 und 19, 109 auf der rechten Seite der Wendestange 58. Alle jeweils nichtgenannten Luftöffnungen bleiben geschlossen, so daß die Blasluft nur durch die benötigten Luftöffnungen entströmt und gegen die Papierbahn geblasen wird.When changing the position of the turning bar 58 by an angle α 2 of 45 ° to a horizontal or extended position II in accordance with the representations according to FIGS. 11 to 13, the longer pin 114 with its second end 117 now comes into engagement with one of the control planes 94, 95, 96 of the control cam 87, so that the slide 98 is displaced by an amount of 3a (FIG. 11), 4a (FIG. 12) or 5a (FIG. 13) against the force of the spring 27, so that on the Side frame 21 facing side 58 each left or right around the turning bar 58 a quarter-web paper 118 or a total of half-web paper 119 can be guided, air flowing out between the paper web 118 or 119 and the turning bar 58, while the air openings not mentioned closed are. 11 to 13, the following air openings are open to one another: in FIG. 11 the air openings 16, 106; 17, 107 for guiding a quarter-wide paper web 118 on the left side of the turning bar 58; in FIG. 12, in addition to the air openings mentioned in FIG. 11, the air openings 18, 108 and 19, 109 for guiding a half-web-wide paper web 119 over the entire width of the side of the turning bar 58 facing the side frame 21; in FIG. 13 only the air openings 18, 108 and 19, 109 last mentioned in FIG. 12 on the right side of the turning bar 58. All air openings not mentioned in each case remain closed, so that the blown air only flows out through the required air openings and is blown against the paper web.

Es ist auch möglich, die Hubbewegung des topfförmigen Schiebers 98 statt eines Steuernockens 88, 89 mit jeweils mehreren Steuerebenen 94, 95, 96 durch ein elektrisches Stellmittel zu erzeugen. Dazu ist in Fig. 16 eine Seitenansicht eines dritten Ausführungsbeispieles eines Antriebes zum Verschließen der Luftöffnungen gezeigt. Die Wendestange 58 befindet sich dabei in einer solchen Stellung, wie sie in Fig. 8 bis 10 gezeigt ist. Ein Wendestangenhalter 59 ist gleitend auf einer Tragspindel 62 angeordnet und mittels einer parallel dazu verlaufenden Gewindespindel 73 in axialer Richtung der Spindeln 62, 73 verschiebbar. Im oder am Wendestangenhalter 59 ist ein Motor 121, z. B. Elektromotor mit nicht näher dargestellten Anschlüssen befestigt, dessen gegenwärtige Stellung und somit die Stellung des Antriebes mittels eines Potentiometers 122 feststellbar ist.It is also possible to generate the lifting movement of the pot-shaped slide 98 instead of a control cam 88, 89 with a plurality of control levels 94, 95, 96 by an electrical actuating means. 16 shows a side view of a third exemplary embodiment of a drive for closing the air openings. The turning bar 58 is in a position such as that shown in FIGS. 8 to 10. A turning bar holder 59 is slidably arranged on a support spindle 62 and can be displaced in the axial direction of the spindles 62, 73 by means of a threaded spindle 73 running parallel thereto. In or on the turning bar holder 59, a motor 121, for. B. electric motor with connections not shown, the current position and thus the position of the drive can be determined by means of a potentiometer 122.

Der Motor 121 ist mittels einer biegsamen Antriebswelle 123, welche durch eine Bohrung 124 des Endstückes 112 der Wendestange 58 hindurchgeführt ist, kraft- und formschlüssig mit einem Zahnrad 126 verbunden, welches mit einem Innenzahnrad 127 kämmt. Das Innenzahnrad 127 ist fest mit dem Innenring eines bekannten Nadellagers 128 verbunden. Der Außenring des Nadellagers 128 ist kraft- und formschlüssig mit dem Innenmantel des Rohres 2 der Wendestange 58 verbunden, so daß das Innenzahnrad 127 ebenfalls drehbar gelagert ist. Auf einer äußeren, dem Wendestangenhalter 59 abgewandten Bodenseite 129 des im Querschnitt topfförmig ausgebildeten Innenzahnrades 127 sind zwei diametral am Umfang der Bodenseite 129 stoffschlüssig angeordnete, sich parallel zur Rotationsachse 8 der Wendestange 58 erstreckende Bolzen 131, 132 mit Laufrollen 137 oder Nocken angeordnet, welche mit auf der Stirnseite eines rohrförmigen Schiebers 133 ausgebildeten Steuerkurven 134, 136 in Wirkverbindung stehen. Die Steuerkurven 134, 136 verlaufen jeweils von 0o bis 180o bzw. von 180o bis 360o und sind gleichförmig zueinander angeordnet, d. h. sie besitzen eine gleiche Steigung. Infolge der motorischen Drehung des Innenzahnrades 127 um maximal 180o mit den auf der äußeren Bodenseite 129 auf Bolzen 131, 132 angeordneten Laufrollen 137 ist der Schieber 133 in Richtung seiner Rotationsachse 8 um maximal fünfmal a, d. h. um fünfmal den Durchmesser einer Luftöffnung in Richtung der in Fig. 16 der nicht dargestellten Feder 27 bewegbar. Somit kann entsprechend der Stellung des Drehwinkels des Innenzahnrades 127 im Bereich zwischen 0o und 180o eine axiale Verschiebung der Luftöffnungen von 0 bis fünfmal a dadurch erfolgen, daß die Enden der Bolzen 131, 132 eine Drehbewegung um maximal 180o ausführen und dabei auf den gleichmäßig ansteigenden Kurven 134, 136 entlangfahren und somit entsprechend den Darstellungen nach Fig. 8 bis 13 ein wahlweises Verschließen der nicht benötigten Luftöffnungen erfolgt. Zum Schutz gegen Verdrehen des Schiebers 133 gegenüber dem Rohr 2 ist zwischen den genannten Teilen eine Paßfeder 138 angeordnet.The motor 121 is non-positively and positively connected to a gear wheel 126 which meshes with an internal gear wheel 127 by means of a flexible drive shaft 123 which is passed through a bore 124 of the end piece 112 of the turning bar 58. The internal gear 127 is firmly connected to the inner ring of a known needle bearing 128. The outer ring of the needle bearing 128 is non-positively and positively connected to the inner jacket of the tube 2 of the turning bar 58, so that the inner gear 127 is also rotatably mounted. On an outer bottom side 129 facing away from the turning bar holder 59 of the internal gear 127 which is cup-shaped in cross section, two bolts 131, 132 with rollers 137 or cams, which are arranged cohesively diametrically on the circumference of the bottom side 129 and extend parallel to the axis of rotation 8 of the turning bar 58, are arranged with on the end face of a tubular slide 133 formed control cams 134, 136 are operatively connected. The control curves 134, 136 each extend from 0 ° to 180 ° or from 180 ° to 360 ° and are arranged uniformly to one another, ie they have the same slope. As a result of the motor rotation of the internal gear 127 by a maximum of 180 o with the rollers 137 arranged on the outer bottom side 129 on bolts 131, 132, the slide 133 is in the direction of its axis of rotation 8 by a maximum of five times a, ie by five times the diameter of an air opening in the direction of 16 of the spring 27, not shown, is movable. Thus, depending on the position of the angle of rotation of the internal gear 127 in the range between 0 o and 180 o, the air openings can be axially displaced from 0 to five times a in that the ends of the bolts 131, 132 perform a rotational movement by a maximum of 180 o and thereby on the Drive along evenly rising curves 134, 136 and, as shown in FIGS. 8 to 13, there is an optional closing of the air openings that are not required. To protect against rotation of the slide 133 opposite a key 138 is arranged between the said parts of the tube 2.

Statt eines elektrisch betriebenen Stellmittels kann auch ein bekanntes pneumatisch oder hydraulisch betriebenes Stellmittel eingesetzt werden.Instead of an electrically operated actuator, a known pneumatically or hydraulically operated actuator can also be used.
