Abstract

The invention relates to an air-circulated turning bar, especially for changing the direction of running material webs. In order to avoid having to stop the machine in order to clean turning bars of this type, there is proposed a turning bar, of which the segments soiled by the deposit of dyestuff can be cleaned while the machine is running. This is achieved in that, for the purpose of cleaning, the turning bar mounted rigidly per se can be rotated and locked in the web running direction while the machine is running. Two air-outlet chambers which can be used alternately are arranged in such a way that only the particular air-outlet chamber facing the web is connected to the eccentrically mounted blowing-air conduit. To form the air-outlet chambers, two tube halves having a web and having two end walls joined together respectively from three parts are welded to one another. The proposed turning bars are provided especially for changing the direction of material webs; however, they can also be used, for example, for supporting a web guided in a straight line. They make it possible to use cleaning appliances and are a detail of the plans for automation. <IMAGE>

Description

Buftumspülte Wendestange, insbesondere ür die Richtungs-Bufted turning bar, especially for the directional

änderung laufender Materialbahnen Die Erfindung betrifft eine luftumspülte Wendestange, wie sie in Rollenrotations-Druckmaschinen, Tapiermaschinen e. dgl., insbesondere für die Richtungsanderung laufender Materialbannen, Verwendung findet.Modification of moving material webs The invention relates to an air bath Turning bar, as used in web-fed rotary printing machines, wallpapering machines e. like., in particular for the change of direction of running material bans, is used.

Bei Vorrichtung der vorstehenden Art ist es bekannt, daß zur Verminderung der Reibung und damit um Verhindern des Abschmierens frischbedruckter Bahnen von Inneren der Wendestange her Blasluft zwischen die Oberfläche der Wendestange und die Bahn gelangt.In the device of the above type, it is known that to reduce the friction and thus to prevent the smearing of freshly printed webs from Inside the turning bar, blown air between the surface of the turning bar and the train arrives.

Zu diesen Zweck werden, wie beispielswise die DE-AS 10 72 080 zeigt, im Berührngsbereich von Bahn und Zylindermantel der Wendestange Bohrungen oder Schlitze, verteilt auf die gesamte Breite, vorgesehen.For this purpose, as for example DE-AS 10 72 080 shows, In the contact area between the track and the cylinder jacket of the turning bar, there are holes or slots, distributed over the entire width, provided.

Es hat sich aber gezeigt, daß sich nach mehr oder weniger langem Einsatz der Wendestange, trotz des Luftpolsters zwischen Bahn und Wendestange, auf dieser ein bestimmter Farbhauch absetzt. Um diesem Übelstand abzuelfen, wurde gemäß DE-AS 20 26 355 das die Bahn stützende Element des Zylindermantels der Wendestange av.swechfelbar und dazu leicht lösbar angeordnet. Dadurch ist es zwar hicht mehr nötig, den gesamten Wendestangenkörper zu reinigen oder zu demontieren, sondern es braucht nur z. B. eiii als segment verwendeter poröser Kartonstreifen ausgewechselt zu werden.But it has been shown that after more or less long use the turning bar, despite the air cushion between track and turning bar, on this a certain hint of color separates. In order to remedy this problem, according to DE-AS 20 26 355 the element of the cylinder jacket of the turning bar that supports the web and arranged to be easily detachable. Because of that it is not necessary anymore, the whole To clean or dismantle turning bar body, but it only needs z. B. Eiii to be replaced as a segment of porous cardboard strips.

Es ist aber notwendig, dazu die Maschine anzuhalten, wodurch Zeitverlust und Makulatur entsteht.However, it is necessary to stop the machine for this, which leads to a loss of time and waste is created.

Die Erfindung stellt sich das Ziel, die Nachteile des Standes der Technik zu vermeiden.The invention has the aim of addressing the disadvantages of the prior art Avoid technology.

Der Erfindung liegt die Aufgabe zugrunde, eine luftumspülte, an sich starr gelagerte Wendestange zu schaffen, deren durch Farbstoff-Ablagerungen verschmutzte Segmente während des Maschinenlaufs gereinigt werden können.The invention is based on the object of providing an air bathed per se To create rigidly mounted turning bar, whose soiled by dye deposits Segments during the Machine run can be cleaned.

Gemäß der Erfindung wird dies dadurch erreicht, daß die Wendestange zum Zwecke der Reinigung während des Maschinenlaufs um 1800 dreh- und arretierbar ist, daß zwei abwechselnd einsetzbare Luftauschilfskammern vorgesehen sind, von denen nur die jeweils bahnseitigs mit der außermittig angeurdneten Blasluftleitung verbindbar ist.According to the invention this is achieved in that the turning bar Can be rotated and locked by 1800 for cleaning purposes while the machine is running is that two air exchange chambers that can be used alternately are provided from which only the one on the railway side with the off-center blown air duct is connectable.

Nach einem weiteres Merkmal der Erfindung können zwei Rohrhälften, mit einem Steg und mit zwei, aus je drei Teilen gefügten Stirnwänden verschweißt sein und die Suftaustrittskammern bilden.According to a further feature of the invention, two tube halves, welded with a bar and with two end walls made of three parts each be and form the Suftaustrittskammer.

Wenn bei entsprechenden Kontrollen eine Verschmutzung festgestellt worden ist, kann die Wendestange leicht von Hand über einen dazu vorgesenenen Handhebel, vorzugsweise in Bannlaufrichtung, um 1800 gedreht werden. Dadurch gelangt das bisher im Bannbereich gelegene Segment der Wendestange aus dem Bahn bereich heraus und kann ohne weiteres während des Maschinenlaufes gereinigt werden.If contamination is found during appropriate checks the turning bar can easily be done by hand using a hand lever provided for this purpose, preferably in the direction of the spell, rotated by 1800. This is how this has happened so far Segment of the turning bar located in the ban area out of the railway area and can easily be cleaned while the machine is running.

Das Drehen kann nstürlich auch mechanisch, dann vorzugsteise mit Bahngeschwindigkeit, erfolgen und die Reinigung mittels eine-r der üblichen Vorrichtungen zum Säubern der Oberfläche von Zylindern. Es ist auci möglich, nic'tit nui zwei, sondern mehrere Luftaustrittskammern vorzusehen; im allgemeinen ist Jedoch nur ein leichtes Absetzen von Farbe über längere ZeiX zu verzeichnen, so daß zwei Kammern ausreichend sein dürften.The turning can of course also be done mechanically, then preferably at web speed, and cleaning using one of the usual cleaning devices the surface of cylinders. It is also possible, not only two, but several Provide air outlet chambers; however, in general there is only slight settling of color can be recorded over a longer period of time, so that two chambers are sufficient should.

Neben dem Vorteil, daß die Reinigung ohne Maschinenstop erfolgen kann, ist die Herstellung der Wendestange noch sehr unkompliziert und ohne weiteres für eine Serienherstellung geeignet.In addition to the advantage that cleaning can be carried out without stopping the machine, the production of the turning bar is still very uncomplicated and straightforward for suitable for series production.
