WendestangeTurning bar
Die Erfindung betrifft eine Wendestange zum Umlenken einer Warenbahn entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a turning bar for deflecting a web according to the preamble of claim 1.
Es ist bekannt, z. B. Papierbahnen inIt is known e.g. B. paper webs in
Rollenrotationsdruckmaschinen nach dem Bedrucken mittels einer oder mehrerer Längssehne i devorri chtungen in zwei oder mehrere Tei lpapierbahnen aufzutei len. Solche Tei lpapierbahnen werden mittels Wendestangen mit oder ohne Umdrehen und in veränderbarer Reihenfolge zu einem Strang übe re i nande rge legt . Die Wendestangen sind in der Regel waagerecht in einem Seitengestell unter einem Winkel von 45° angeordnet.Rotary printing presses after printing using one or more longitudinal chords in two or more partial paper webs. Such partial paper webs are laid over by turning bars with or without turning over and in a changeable order to form a strand. The turning bars are usually arranged horizontally in a side frame at an angle of 45 °.
Erfolgt bei einem se i t engeste l Ipa ra l le len Verlauf einer Tei lpapierbahn anstelle einer Zuführung der Tei lpapierbahn durch die linke Gestellseite eine Zuführung der Tei lpapierbahn durch die rechte Geste 11se i te, z. B. zum Einmischen von Papierbahnen/ so ist es bei o. g. Wendestangenanordnung nachtei lig, daß die Wendestange entweder umgebaut oder ausgetauscht werden muß, damit zwischen Wendestange und Tei lpapierbahn jewei ls ein Luftpolster vorhanden ist.If a part paper web runs along a narrow path, instead of feeding the part paper web through the left frame side, the part paper web is fed through the right gesture 11 side, e.g. B. for mixing paper webs / so it is in the above-mentioned turning bar arrangement nachtei lig that the turning bar must either be converted or replaced so that between the turning bar and Tei lpapierbahn jewei ls an air cushion is available.
Weiterhin ist durch die DE 41 30 678 A1 eine Wendestange bekannt, welche eine neben dem Führungsbereich der Tei lpapierbahn angeordnete Wendelnut zum Führen eines Einziehbandes aufweist.Furthermore, DE 41 30 678 A1 is a turning bar known, which has a spiral groove arranged next to the guide region of the partial paper web for guiding a pull-in belt.
Nachteilig dabei ist, daß das Einziehband beim Umfahren dieser Wendestange einen großen Reibungswiderstand zu überwinden hat. Infolge der dabei im Einziehband auftretenden hohen Zugkräfte können diese zum Zerreißen desselben führen.The disadvantage here is that the pull-in belt has to overcome a large frictional resistance when driving around this turning bar. As a result of the high tensile forces that occur in the pull-in belt, they can tear the same.
Der Erfindung liegt die Aufgabe zugrunde, eine von "zwei Seiten" umfahrbare, Wendestange zu schaffen.The object of the invention is to create a turning bar that can be bypassed from "two sides".
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of claim 1.
Die mit der Erfindung erzielbaren Vortei le bestehen darin, daß die Wendestange beidseitig, d. h. von einer linken Seite oder Hälfte (Fig. 2) oder von einer rechten Seite oder Hälfte (Fig. 3) umfahren werden kann. Die der Papierbahn zugewandte Hälfte weist jeweils Luftaust ri t t söf fnungen auf, die mit wenig Aufwand durch eine halbe Umdrehung des Rohres umstellbar sind. Somit kann ein Umbau oder Austausch von Wendestangen insbesondere dann vermieden werden, wenn Te 1 Ipapi e rbahnen in sogenannten Mischtürmen an anderer Stelle, d. h. in einer anderen Ebene des Mischturmes eingemischt werden. Weiterhin ist von Vortei l, daß auf einer Halterung der erfindungsgemäßen Wendestange eine wendeiförmige, druck luf tbebl asene Führungsnut zur leichtgängigen Führung für ein Einziehband vorgesehen ist. Dabei erfolgt vortei lhafterweise ein selbsttätiges Beblasen der Führungsnut nur für die Zeitspanne des tatsächlichen Durchlaufes des Einziehbandes.The Vortei le achievable with the invention are that the turning bar on both sides, ie from a left side or half (Fig. 2) or from a right side or half (Fig. 3) can be avoided. The half facing the paper web has air openings which can be changed with little effort by half a turn of the tube. In this way, a conversion or exchange of turning bars can be avoided in particular if Te 1 Ipapi e rbahnen in so-called mixing towers are mixed in at a different location, ie in another level of the mixing tower. Furthermore, it is of advantage that A holder of the turning bar according to the invention is provided with a helical, compressed air guide groove for smooth guidance for a pull-in belt. Advantageously, there is an automatic blowing of the guide groove only for the period of the actual passage of the feed belt.
Darüberhinaus ist es für eine universelle Ei nsetzbarkei t der Wendestange weiterhin von Vortei l, wenn auf der Halterung eine im Gegendrehsinn zur ersten Führungsnut angeordnete zweite Führungsnut vorgesehen ist.In addition, it is also of advantage for a universal applicability of the turning bar if a second guide groove arranged in the opposite direction to the first guide groove is provided on the holder.

Eine Wendestange 1 besteht aus einem mit Luf taust ri tt söffnungen 2 versehenem Rohr z. B. Führungsrohr 3. Das Führungsrohr 3 Ist beidendig über Lagerbuchsen 4; 6 in se i tengeste l Ifesten Halterungen 7; 8 in einem Winkel von 45° zur Papierbahnlaufrichtung, z. B. mittels ni chtdargeste l Iter Schellen ggf., auch an sei tengestel Ifesten Traversen, angeordnet. Die Luftaustrittsöffnungen 2 sind am Umfang des Führungs rohres 3 in einem Winkel Alpha kleiner 165° und auf einer Länge vertei lt, die einer Papierbahnbreite abzüglich eines Betrages, z. B. 30 mm für einen überstand entspricht. Beide Halterungen 7; 8 sind durch ein Verbi ndungs rohr 9, welches beide Halterungen 7; 8 auf Abstand hält, miteinander fest verbunden. Das Verbindungsrohr 9 weist über seine gesamte Länge und seinen Umfang verteilt Luftaustrittsöffnungen 11 auf. Das Verbl ndungs rohr 9 Ist an einem Ende mit einem in der rechten Halterung 8 befindlichen Anschluß 10 für Niederdruck-Blas luft mit einem Luftdruck von z. B. 0,3 bis 0,6 bar verbunden. Das Führungsrohr 3 ist aus einer ersten Endlage A (Fig. 1 und 2) um 180° um seine Rotationsachse 5 in eine zweite Endlage B rotierbar (Fig. 3)A turning bar 1 consists of a pipe with air openings ri tt openings 2 z. B. Guide tube 3. The guide tube 3 is at both ends via bushings 4; 6 in the side view of holders 7; 8 at an angle of 45 ° to the paper web direction, z. B. by means of ni chtdargest l Iter clamps if necessary, also on beengestel Ifesten trusses, arranged. The air outlet openings 2 are on the circumference of the guide tube 3 at an angle alpha less than 165 ° and distributed over a length which is a paper web width minus an amount, for. B. corresponds to 30 mm for a protrusion. Both brackets 7; 8 are through a connec tion tube 9, which both brackets 7; 8 keeps at a distance, firmly connected. The connecting pipe 9 has air outlet openings 11 distributed over its entire length and circumference. The Verbl ndungs tube 9 is at one end with a connector 10 located in the right bracket 8 for low-pressure air with an air pressure of z. B. 0.3 connected up to 0.6 bar. The guide tube 3 can be rotated from a first end position A (FIGS. 1 and 2) through 180 ° about its axis of rotation 5 into a second end position B (FIG. 3)
Dabei ist das Führungsrohr 3 in seiner jewei ligen Endlage A; B fixierbar gelagert. Das kann z. B. dadurch erreicht werden, daß an einer Stirnseite des Führungs rohres 3 zwei sich diametral am Umfang gegenüberliegende halbkreisförmige Ausnehmungen 12; 13 angeordnet sind, wobei wahlweise jewei ls eine Ausnehmung 13 gegen einen in radialer Richtung zum Führungsrohr 3 bewegbaren Arretierungsgriff 14 einrastend wirkt. Der Arretierungsgriff 14 wird gegen die Kraft einer Feder 15 bewegt, welche sich zwischen dem Kopf eines ha Iterungsfesten Gewindebolzens 31 und einem Bund 32 des Arretierungsgriffes 14 abstützt.The guide tube 3 is in its respective end position A; B stored fixable. That can e.g. B. can be achieved in that on one end of the guide tube 3 two diametrically opposite circumferential semicircular recesses 12; 13 are arranged, with either a recess 13 acting against a locking handle 14 movable in the radial direction of the guide tube 3. The locking handle 14 is moved against the force of a spring 15, which is supported between the head of a ha ition-resistant threaded bolt 31 and a collar 32 of the locking handle 14.
Die Lagerbuchsen 4; 6 können aus Kunststoff bestehen und auf die Halterung 7; 8 aufgepreßt sein. Zur Abdichtung der Ni ederdruck-B las luft gegen Ausströmen durch die Spalten der G le i t Lagerung sind Dichtringe 16; 17 ei ngesetzt .The bearing bushes 4; 6 can consist of plastic and on the bracket 7; 8 be pressed on. Sealing rings 16 are used to seal the low-pressure compressed air against leakage through the gaps in the slide bearing; 17 set.
Eine Halterung 7 des Führungsrohres 3 weist eine wendeiförmige Führungsnut 18 zur Aufnahme eines nichtdargestellten Einzugsbandes für eine Warenbahn auf. Auf dem Nutgrund oder der Bodenfläche 19 der Nut befinden sich Luftaustrittsöffnungen 21 bis 25, welche als Radialbohrungen ausgeführt sind und in eine axiale zentrale Bohrung 27 der linken Halterung 7 münden. Vortei lhafterweise ist am Ende jederA holder 7 of the guide tube 3 has a helical guide groove 18 for receiving a feed belt (not shown) for a web. On the groove base or the bottom surface 19 of the groove there are air outlet openings 21 to 25 which are designed as radial bores and into an axial one central bore 27 of the left bracket 7 open. Advantageously everyone is in the end
Luftaustrittsöffnung 21 bis 25 in der Bodenfläche 19 der Nut 18 jeweils ein bekanntes Kugelsitzventil 33 so angeordnet, daß beim Durchlauf des Einziehbandes ein öffnen des Kuge Is 1 tzvent i les 33 erfolgt (Fig. 4). Somit kann sich zwischen der Unterseite des Einziehbandes und der Führungsnut 18 ein Luftpolster ausbilden, welches die Reibung zwischen beiden Tei len vermindert. Die axiale Bohrung 27 steht mit einem an bzw. in der Halterung 7 befindlichen Anschluß 28 fürAir outlet opening 21 to 25 in the bottom surface 19 of the groove 18 each have a known ball seat valve 33 arranged so that the passage of the feed belt opens the ball Is 1 tzvent i les 33 (Fig. 4). Thus, an air cushion can form between the underside of the feed belt and the guide groove 18, which reduces the friction between the two parts. The axial bore 27 is with a connection 28 located on or in the holder 7 for
Hochdruc k-B las luft mit einem Luftdruck von z. B. 1,5 bis 4 bar in Verbindung. Die wendeiförmige Führungsnut 18 vollführt auf dem Umfang der linken Halterung 7 eine halbe Drehung, so daß es möglich wird, ein Einziehband für eine Warenbahn, z. B. eine Papierbahn 29 leichtgängig über die Wendestange 1 zu führen.Hochdruc k-B read air with an air pressure of z. B. 1.5 to 4 bar in connection. The helical guide groove 18 makes a half turn on the circumference of the left bracket 7, so that it becomes possible to use a pull-in tape for a web, e.g. B. to run a paper web 29 smoothly over the turning bar 1.
Für eine universelle Ei nsetzbarke i t der Wendestange 1 ist es weiterhin von Vorteil, wenn zumindest eine, z. B. die linke Halterung 7 eine im Gegendrehsinn zur ersten Führungsnut 18 angeordnete zweite Führungsnut 34 aufweist. Diese Führungsnut 34 ist ebenso wie die vorbeschriebene Führungsnut 18 ausgebi ldet und mit ni chtbezei chneten Luftaustrittsöffnungen bestückt. Es Ist auch möglich, die rechte Halterung 8 mit einer Führungsnut 18 oder mit einer zweiten Führungsnut 34 auszubi Iden. Es ist weiterhin möglich, auf beiden Halterungen 7; 8 der Wendestange 1 eine Führungsnut einzubringen, wobei die Führungsnuten dann gegensinnig zueinander verlaufen sollten. In diesem Falle ist dann auch noch ein separater Anschluß für Hochdruck-B las luft vorgesehen. For a universal egg nsetzbarke it the turning bar 1, it is also advantageous if at least one, for. B. the left bracket 7 has a second guide groove 34 arranged in the opposite direction to the first guide groove 18. This guide groove 34 is formed in the same way as the guide groove 18 described above and is equipped with non-specific air outlet openings. It is also possible to design the right holder 8 with a guide groove 18 or with a second guide groove 34. It is also possible on both brackets 7; 8 of the turning bar 1 to introduce a guide groove, the guide grooves should then run in opposite directions to each other. In this case there is also a separate connection for high pressure blow air.
