Abstract

Um nicht benötigte Luftaustrittslöcher in sogenannten luftumspülten Wendestangen zu verschließen, werden in dem äußeren Rohr der Wendestange einzelne, in Achsrichtung nebeneinander angeordnete innere Rohrstücke verwendet, die axial fixiert, jedoch in Umfangsrichtung drehbar sind. In den inneren Rohrstücken sind Öffnungen, bzw. in Umfangsrichtung verlaufende Schlitze vorgesehen. Einem jeden der inneren Rohrstücke ist eine, das äußere Rohr durchsetzende Öffnung zugeordnet, durch die von außen her durch ein Stellmittel das jeweilige, unterhalb der Ausnehmung liegende innere Rohrstück in die gewünschte Umfangslage gebracht werden kann, sodaß die nicht benötigten Luftaustrittslöcher im äußeren Rohr bedeckbar oder beim Korrespondieren des Schlitzes in dem inneren Rohrstück mit einem Luftaustrittsloch im äußeren Rohr freigebbar sind.In order to close unnecessary air outlet holes in so-called air-swept turning bars, individual inner tube pieces arranged axially next to one another are used in the outer tube of the turning bar, which are axially fixed but rotatable in the circumferential direction. Openings or slots running in the circumferential direction are provided in the inner tube pieces. Each of the inner tube pieces is assigned an opening which penetrates the outer tube, through which the respective inner tube piece lying below the recess can be brought into the desired circumferential position from the outside by an adjusting means, so that the air outlet holes in the outer tube which are not required can be covered or when the slot in the inner tube piece corresponds to an air outlet hole in the outer tube can be released.

Description

Die Erfindung betrifft eine blasluftbeaufschlagte Wendestange zum Umlenken von Druckträgerbahnen, bestehend aus einem mit Luftaustrittsöffnungen versehenen äußeren Rohr und einer Einrichtung zur Abdeckung von durch die Druckträgerbahn nicht abgedeckten Luftaustrittsöffnungen.The invention relates to a blast-air-actuated turning bar for deflecting pressure carrier webs, consisting of an outer tube provided with air outlet openings and a device for covering air outlet openings not covered by the pressure carrier web.

Aus der DE-AS 2 026 355 ist bereits eine sogenannte luftumspülte Wendestange zum Umlenken von Papierbahnen bekannt, bei der durch die von der umzulenkenden Papierbahn nicht abgedeckten Luftaustrittsöffnungen durch außen auf der Wendestange fixierbare Abdeckbleche verschließbar sind. Derartige Abdeckbleche außen auf der Wendestange sind störend und können zur Beschädigung der Papierbahn bei nicht sorgfältigerArbeitsweise des Druckpersonals führen. Mit dieser bekannten Abdeckmethode ist außerdem eine individuelle Abdeckung von einzelnen, nicht benötigten Luftaustrittsöffnungen nicht möglich, sondern lediglich die Randbereiche der Wendestange.From DE-AS 2 026 355, a so-called air-swept turning bar for deflecting paper webs is already known, in which the air outlet openings not covered by the paper web to be redirected can be closed by cover plates which can be fixed on the outside of the turning bar. Such cover plates on the outside of the turning bar are disruptive and can lead to damage to the paper web if the printing personnel are not careful. With this known covering method, individual covering of individual, unneeded air outlet openings is also not possible, but only the edge regions of the turning bar.

Aufgabe der Erfindung ist es, eine Einrichtung aufzuzeigen, mit der nicht benötigte Luftaustrittsöffnungen individuell vom Inneren der Wendestange her verschließbar sind.The object of the invention is to show a device with which air outlet openings which are not required can be closed individually from the inside of the turning bar.

Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen:

  • Figur 1: eine Teilansicht von zwei zwischen Seitenwänden gelagerten Wendestangen;
  • Figur 2: einen Teilschnitt durch eine Wendestange;
  • Figur 3: einen Schnitt entlang der III-III der Wendestange gemäß Figur 2;
  • Figur 4: ein zweites Ausführungsbeispiel der Erfindung und
  • Figur 5: ein drittes Ausführungsbeispiel der Erfindung.
This object is achieved by applying the features of the characterizing part of claim 1. Further developments of the invention result from the subclaims and from the description in conjunction with the drawings. In these show:
  • FIG. 1: a partial view of two turning bars mounted between side walls;
  • Figure 2: a partial section through a turning bar;
  • Figure 3 shows a section along the III-III of the turning bar according to Figure 2;
  • Figure 4: a second embodiment of the invention and
  • Figure 5: a third embodiment of the invention.

Bei dem ersten Ausführungsbeispiel gemäß Figur 1 sind zwei Enden einer herkömmlich zwischen zwei Maschinenseitenwänden 1, 2 auf einer Traverse 3 gelagerten, durch eine Gewindespindel 4 verschiebbaren Wendestangen 5, 6 gezeigt. Diese Wendestangen 5, 6 weisen eine Anzahl von Luftaustrittsöffnungen 7, 8, 9 auf, die üblicherweise im Bereich der einlaufenden und ablaufenden Papierbahn, d.h. etwa 180° zueinander versetzt, in Reihen angeordnet sind.In the first exemplary embodiment according to FIG. 1, two ends of a turning bar 5, 6, which is conventionally mounted between two machine side walls 1, 2 on a crossbar 3 and can be displaced by a threaded spindle 4, are shown. These turning bars 5, 6 have a number of air outlet openings 7, 8, 9, which are usually in the area of the incoming and outgoing paper web, i.e. about 180 ° to each other, are arranged in rows.

Figur 2 zeigt einen Teilschnitt durch die Wendestange 6, an dem im folgenden die erfindungsgemäße Einrichtung zum wahlweisen Verschließen und Freigeben von Luftaustrittsöffnungen 7, 8, 9 erläutert wird.FIG. 2 shows a partial section through the turning bar 6, on which the device according to the invention for optionally closing and releasing air outlet openings 7, 8, 9 is explained below.

Die in den Figuren 1 und 2 gezeigte Wendestange 6 besteht aus einem äußeren Rohr 11, in das eine Anzahl Rohrstücke 12 eingeschoben sind. Bei dem Ausführungsbeispiel ist die Länge dieser Rohrstücke 12 etwas größer als der Abstand von zwei benachbarten Luftaustrittsöffnungen 9 in einer Lochreihe, sodaß mit einem Rohrstück 12 jeweils zwei, in Axialrichtung benachbarte Luftaustrittsöffnungen 9 abdeckbar oder freigebbar sind. In Umfangsrichtunr weist jedes dieser Rohrstücke 12 Vertiefungen ,bzw. Ausnegen 1C auf. Figur 2 läßt erkennen, daß aus Gründen der Wärmeausdehnung jeweils zwischen zwei benachbarten Rohrstücken 12 ein kleiner Abstand vorgesehen ist, wobei durch die Ausbildung der Enden der Rohrstücke 12 die Abdichtung und Lagestabilität des Systemes trotzdem gewährleistet sind. Die Rohrstücke 12 weisen in Umfangsrichtung verlaufende Durchbrüche, bzw. Schlitze 13 auf, die durch Verdrehen der inneren Rohrstücke 12 zu den Luftaustrittsöffnungen 7, 8, 9 so einstellbar sind, daß einige oder alle dieser Luftaustrittsöffnungen 7, 8, 9 geöffnet oder verschlossen sind. Bekanntlich wird derartigen, sogenannten luftumspülten Wendestangen Druckluft (bspw. axial) zugeführt, die zur besseren Führung der umzulenkenden Druckträgerbahn aus den genannten Luftaustrittsöffnungen auszuströmen vermag. Durch die umfangsmäßige Versetzung der Schlitze 13 in den inneren Rohrstücken 12 kann eine weitere Einflußnahme auf die abzudeckenden Luftaustrittsöffnungen 7 bis 9 erreicht werden.The turning bar 6 shown in Figures 1 and 2 consists of an outer tube 11, into which a number of pipe sections 12 are inserted. In the exemplary embodiment, the length of these tube pieces 12 is slightly greater than the distance from two adjacent air outlet openings 9 in a row of holes, so that two tube outlet openings 9, which are adjacent in the axial direction, can be covered or released with one tube piece 12. In the circumferential direction, each of these tube pieces has 12 depressions or. Ausnegen 1C on. Figure 2 shows that for reasons of thermal expansion, a small distance is provided between two adjacent pipe sections 12, the sealing and positional stability due to the formation of the ends of the pipe sections 12 of the system are still guaranteed. The pipe sections 12 have openings or slots 13 running in the circumferential direction, which can be adjusted by rotating the inner pipe sections 12 to the air outlet openings 7, 8, 9 so that some or all of these air outlet openings 7, 8, 9 are opened or closed. It is known that compressed air (for example axially) is fed to such, so-called air-swept turning bars, which can flow out of the air outlet openings mentioned for better guidance of the pressure carrier web to be deflected. Due to the circumferential displacement of the slots 13 in the inner pipe sections 12, a further influence on the air outlet openings 7 to 9 to be covered can be achieved.

Durch die erfindungsgemäßen Durchbrüche, bzw. Öffnungen 14 im Mantel des äußeren Rohres 11 für ein jedes der Rohrstücke 12 wird in einfacher Weise ermöglicht, daß die inneren axial geführten Rohrstücke 12 in Umfangsrichtung drehbar sind. Bei dem Ausführungsbeispiel gemäß Figuren 1 und 2 ist dies in folgender Weise möglich: Die inneren Rohrstücke 12 weisen in Umfangsrichtung verlaufende Vertiefungen 10 auf, die an einer Seite mit einer Verzahnung 15 versehen sind,in die ein, ebenfalls mit einer Verzahnung versehener Kegel 16 eingreift. Der Kegel 16 ist mit einem, die Öffnung 14 des äußeren Rohres 11 durchsetzenden Stellknopf 17 verbunden, sodaß bei einem Verdrehen des Stellknopfes 17 manuell oder mit Hilfe eines geeigneten fernbedienbaren Stellmotores oder mittels biegsamer Wellen von einem Bedienungsstand aus eine Drehung des inneren Rohrstückes 12 von außen her in der Weise möglich ist, daß wahlweise nicht benötigte Löcher, bzw. Lochreihen verschließ- oder freigebbar sind. Durch ein herkömmliches, in einem der Löcher (z.B. 7) vorgesehenes Begrenzungsmittel, z.B. einer Spannhülse, ist es möglich, eine Begrenzung für die Verdrehung der inneren Rohrstücke 12 vorzusehen, was die individuelle Anzeige mittels herkömmlicher Meßmittel der jeweiligen umfangsmäßigen Lage der inneren Rohrstücke 12 erleichtert. Die Verwendung einer Spannhülse hat den Vorteil, daß das Luftloch, in dem sie verwendet wird,nicht verschlossen wird.The openings or openings 14 according to the invention in the jacket of the outer tube 11 for each of the tube pieces 12 enable the inner axially guided tube pieces 12 to be rotated in the circumferential direction in a simple manner. In the exemplary embodiment according to FIGS. 1 and 2, this is possible in the following way: The inner tube pieces 12 have recesses 10 running in the circumferential direction, which are provided on one side with a toothing 15 into which a cone 16, also provided with a toothing, engages . The cone 16 is connected to a control knob 17 passing through the opening 14 of the outer tube 11, so that when the control knob 17 is turned manually or with the aid of a suitable remote-controlled servomotor or by means of flexible shafts, the inner tube section 12 is rotated from the outside from a control station forth in the way it is possible that holes that are not required, or rows of holes, can be closed or released. By means of a conventional limiting means, for example an adapter sleeve, provided in one of the holes (for example 7), it is possible to provide a limitation for the rotation of the inner tube pieces 12, which the individual display by means of conventional measuring means of the respective circumferential position of the inner tube pieces 12 facilitates. The use of an adapter sleeve has the advantage that the air hole in which it is used is not closed.

Ein weiterer wesentlicher Vorteil des Ausführungsbeispieles gemäß Figuren 1 und 2 bietet die Verwendung einer Führungshülse 18, die bspw. in der Öffnung 14 des äußeren Rohres 12 eingeklebt sein kann. Die Führungshülse 18 weist einen unteren Vorsprung 19 auf, der in die Vertiefung 10 des inneren Rohrstückes 12 eingreift, und zwar in der Weise, daß der mit einer Verzahnung versehene Kegel 16 in die seitliche Verzahnung 15 eingreift und gleichzeitig das innere Rohrstück 12 gegen axiale Verschiebung fixiert wird. Dafür wird ein Vorsprung 19 an der Führungshülse 18 verwendet. Zwecks besserer Einstellung der umfangsmäßigen Lage der inneren Rohrstücke 12 kann an den Stellknöpfen 17 jeweils eine Rasterung 20 mit einer Kugel 21 verwendet werden. Dadurch ist eine definierte Einstellung der umfangsmäßigen Lage der inneren Rohrstücke 12 möglich.A further essential advantage of the exemplary embodiment according to FIGS. 1 and 2 is the use of a guide sleeve 18, which can be glued, for example, in the opening 14 of the outer tube 12. The guide sleeve 18 has a lower projection 19 which engages in the recess 10 of the inner tube piece 12, in such a way that the toothed cone 16 engages in the side toothing 15 and at the same time the inner tube piece 12 against axial displacement is fixed. For this purpose, a projection 19 on the guide sleeve 18 is used. In order to better adjust the circumferential position of the inner tube pieces 12, a catch 20 with a ball 21 can be used on the adjusting knobs 17. A defined setting of the circumferential position of the inner tube pieces 12 is thereby possible.

Im folgenden wird anhand von Figur 4 eine weitere Ausführungsform der Erfindung beschrieben. Figur 4 zeigt das linke Ende einer herkömmlichen Wendestange 22, die aus einem äußeren Rohr 23 besteht. In dem äußeren Rohr 23 sind wiederum eine Anzahl nebeneinanderliegender Rohrstücke 24 angeordnet. Das äußere Rohr 23 weist in mehreren Lochreihen Austrittsöffnungen 25 auf. Hier ist es vorteilhaft, ebenfalls eine Rasterung, z.B. eine Blechraste zur eindeutigen Fixierung der Rohrstücke zu verwenden.A further embodiment of the invention is described below with reference to FIG. 4. Figure 4 shows the left end of a conventional turning bar 22, which consists of an outer tube 23. A number of adjacent pipe sections 24 are in turn arranged in the outer pipe 23. The outer tube 23 has outlet openings 25 in several rows of holes. Here it is advantageous to also use a grid, e.g. use a sheet metal catch to clearly fix the pipe sections.

Einem jeden Rohrstück 24 ist in dem äußeren Rohr 23 ein Durchbruch, bzw. eine öffnung 26 zugeordnet. Dadurch kann manuell, z.B. mittels des Zeigefingers, das innere Rohr 24 radial verdreht werden, sodaß die in diesem vorgesehenen Öffnungen, bzw. Schlitze die gewünschten Luftaustrittslöcher 25 im äußeren Rohr 22 freigeben oder abdecken. Zur erleichterten Einstellung sind die inneren Rohrstücke 24 an den Drehbereichen unterhalb der öffnungen 26 geriffelt.An opening or opening 26 is assigned to each tube piece 24 in the outer tube 23. This allows the inner one to be moved manually, for example using the index finger Tube 24 are rotated radially, so that the openings or slots provided in this release or cover the desired air outlet holes 25 in the outer tube 22. For easier adjustment, the inner tube pieces 24 are corrugated at the rotating areas below the openings 26.

i Eine weitere Ausführungsvariante der Erfindung ist in Figur 5 gezeigt. Die Wendestange 28 besteht wiederum aus einem, mit Luftaustrittsöffnungen 29 versehenen äußeren Rohr 30. In dem äußeren Rohr 30 liegen nebeneinander eine Anzahl innerer Rohrstücke 32. Einem jeden Rohrstück 32 ist eine Ausnehmung 31 im äußeren Rohr 30 zugeordnet. Parallel zu dem äußeren Rohr 30 ist eine Halterung 33 gezeigt, die zur Führung, bzw. Lagerung von Stellrädern 34 verwendet wird. Einem jeden inneren Rohr 32 ist ein Stellrad 34 zugeordnet, das durch die Ausnehmung 31 hindurch form- oder zumindest reibschlüssig in der Weise mit einem Rohrstück 32 verbunden ist, daß durch Drehen der Stellräder 34 auch das zugeordnete innere Rohrstück 32 verdreht wird, um bestimmte Luftaustrittslöcher 29 freizugeben oder zu verschließen.A further embodiment variant of the invention is shown in FIG. 5. The turning bar 28 in turn consists of an outer tube 30 provided with air outlet openings 29. A number of inner tube pieces 32 lie side by side in the outer tube 30. A recess 31 in the outer tube 30 is assigned to each tube piece 32. In parallel to the outer tube 30, a holder 33 is shown, which is used for guiding or mounting adjusting wheels 34. Each inner tube 32 is associated with a setting wheel 34, which is connected through the recess 31 through or at least frictionally in such a way to a pipe section 32 that by rotating the setting wheels 34 the associated inner pipe section 32 is rotated to certain air outlet holes 29 to release or lock.

Es versteht sich, daß die in den Figuren 1 bis 5 gezeigten Ausführungsbeispiele auch dahingehend erweitert werden können, daß die Einstellmittel unter Zuhilfenahme von bspw. Stellmotoren oder biegsamen Wellen fernbedienbar ausgestaltet werden.It goes without saying that the exemplary embodiments shown in FIGS. 1 to 5 can also be expanded to the effect that the setting means can be designed to be remotely operated with the aid of, for example, servomotors or flexible shafts.
