Abstract

PCT No. PCT/AT88/00043 Sec. 371 Date Feb. 2, 1989 Sec. 102(e) Date Feb. 2, 1989 PCT Filed Jun. 3, 1988 PCT Pub. No. WO88/09726 PCT Pub. Date Dec. 15, 1988.In a device for applying fluid substances in printing and coating machines, carrying plates are fixed to ends of a carrying beam. The carrying plates have recesses therein in which pivot axles of a coating roller are loosely and rotatably mounted. Stopping surfaces are provided to limit lateral movement of the coating roller by abutting with its pivot axles. The stopping surfaces are formed adjacent the recesses formed in the carrying plates and converge in the direction in which a fabric strip which is to be printed on is moved beneath the roller.

Description

Die Erfindung bezieht sich auf eine Einrichtung zum Auftragen fließfähiger Substanzen in Druck- und Beschichtungsmaschinen mit einer magnetisch angepreßten Auftragungswalze, wobei Anlaufflächen für die Enden der Auftragungswalze vorgesehen sind, welche in der Bewegungsrichtung des unteren Teils der Auftragungswalze konvergieren.The invention relates to a device for applying flowable substances in printing and coating machines with a magnetically pressed application roller, wherein contact surfaces are provided for the ends of the application roller, which converge in the direction of movement of the lower part of the application roller.

Eine derartige Einrichtung ist in AT-B-347 388 geoffenbart. Die beschriebenen Anlaufflächen sollen dabei verhindern, daß eine fallweise Schrägstellung der Auftragungswalze zu deren seitlichem Auswandern führt. Dies wird gemäß AT-B-347 388 durch an feststehenden Führungskörpern angebrachte Anlaufflächen erreicht, wogegen die Auftragungswalze selbst lose in der Einrichtung liegt und nur mit der Hand daraus zu entfernen ist.Such a device is disclosed in AT-B-347 388. The contact surfaces described are intended to prevent a case-by-side inclination of the application roller leading to its lateral migration. According to AT-B-347 388, this is achieved by contact surfaces attached to fixed guide bodies, whereas the application roller itself lies loosely in the device and can only be removed from it by hand.

Die Vermeidung von Schubkräften in Axialrichtung der Auftragungswalze durch schräge Anlaufflächen kann in kinematischer Umkehrung der bisher geschilderten Anordnung auch verwirklicht werden, wenn die Führungskörper als Zapfen ausgebildet sind, welche in schräge Ausnehmungen in den Enden der Auftragungswalze eingreifen.The avoidance of shear forces in the axial direction of the application roller by oblique contact surfaces can also be realized in a kinematic reversal of the arrangement described above if the guide bodies are designed as pins which engage in oblique recesses in the ends of the application roller.

Es ist andererseits auch schon bekannt, an einem parallel zur Auftragungswalze verlaufenden Tragholm Tragplatten vorzusehen, welche Ausnehmungen aufweisen, die lose die Achszapfen der Auftragungswalze umfassen. Solche Tragplatten haben die Funktion, das Einführen der Walze insbesondere in eine Rundschablone und das Ausheben derselben zu erleichtern.On the other hand, it is also known to provide support plates on a support spar running parallel to the application roller, which have recesses which loosely encompass the journal of the application roller. Such support plates have the function of facilitating the insertion of the roller, in particular in a circular template, and the removal of the same.

Ein wesentlicher Vorteil der magnetischen Anpressung von Rollrakeln liegt darin, daß hierbei über die Enden der Rakel keine wesentlichen Kräfte eingeleitet werden, so daß es zu keiner systematischen Durchbiegung derselben kommt. Um diesen Vorteil zu gewährleisten, sind die vorgesehenen Tragplatten nicht als Lager ausgebildet, welches die Position der Achszapfen fixiert, sondern als eine Art Käfig, welcher horizontale Auslenkungen begrenzt und ein Ausheben und Transportieren ermöglicht. Durch das Spiel der Rakelwalze in den Tragplatten und durch betriebstechnisch bedingte fallweise Schrägstellung der Rundschablone zur Laufrichtung liegt die Rakelwalze mitunter nicht rechtwinklig zur Laufrichtung, was, durch Abrollen und Anpressen bedingt, eine Funktionsstörung durch seitliches Auswandern bewirken kann. Dabei entsteht eine erhebliche Schubkraft in Axialrichtung dieser Walze, die besonders bei langen Walzen dazu führt, daß Anlaufplatten, die zur Begrenzung der Walzenquerbewegung vorgesehen werden, sich in die senkrecht zur Walzenachse stehenden Anlaufplatten einbohren und diese beschädigen.A major advantage of the magnetic pressing of roller doctor blades is that no significant forces are introduced over the ends of the doctor blade, so that there is no systematic deflection of the same. In order to ensure this advantage, the support plates provided are not designed as a bearing which fixes the position of the axle journals, but as a kind of cage which limits horizontal deflections and enables lifting and transport. Due to the play of the squeegee roller in the support plates and due to operational reasons occasionally inclined the round stencil to the running direction, the squeegee roller is sometimes not at right angles to the running direction, which, due to rolling and pressing, can cause a malfunction due to lateral migration. This creates a considerable thrust in the axial direction of this roller, which, especially with long rollers, leads to thrust plates which are intended to limit the transverse movement of the roller boring into and damaging the thrust plates which are perpendicular to the roller axis.

Aufgabe der Erfindung ist es, die Vorteile der beiden bekannten Einrichtungen zu vereinigen und gleichzeitig das Problem zu lösen, welches dadurch entsteht, daß die Höhe der Tragplatten durch die Dicke der jeweils verwendeten Auftragungswalze bestimmt ist, sodaß die Tragplatten nicht gleichzeitig zur Substanzbegrenzung verwendet werden können. Die gestellte Aufgabe wird dadurch gelöst, daß die Anlaufflächen an von einem Tragholm getragenen Tragplatten vorgesehen sind, welche Ausnehmungen zur Aufnahme von Achszapfen der Auftragungswalze aufweisen, und daß zwischen den Tragplatten und der Auftragungswalze seitliche Substanzbegrenzungsplatten angeordnet sind, welche von den Achszapfen der Auftragungswalze durchsetzt sind.The object of the invention is to combine the advantages of the two known devices and at the same time to solve the problem which arises in that the height of the support plates is determined by the thickness of the application roller used in each case, so that the support plates cannot be used at the same time for substance limitation . The object is achieved in that the contact surfaces are provided on support plates carried by a support bar, which have recesses for receiving axle journals of the application roller, and in that lateral substance limitation plates between the support plates and the application roller are arranged, which are penetrated by the journal of the application roller.

Vorzugsweise können bei einer solchen Einrichtung die Tragplatten selbst aus Stahl hergestellt sein, da sie während des Betriebs kaum mit der Auftragungswalze in Berührung kommen, während ihre Ausnehmungen mit vorzugsweise als Kunststoffkörper ausgebildeten Verschlußplatten versehen sein können, die die Anlaufflächen aufweisen und mit den Tragplatten verschraubt sind.With such a device, the support plates themselves can preferably be made of steel, since they hardly come into contact with the application roller during operation, while their recesses can be provided with closure plates, preferably formed as plastic bodies, which have the contact surfaces and are screwed to the support plates .

Während es bisher üblich war, die zur seitlichen Begrenzung der vor der Auftragungswalze liegenden Substanz dienenden Begrenzungsplatten in den Tragplatten zu lagern, erlaubt es die erfindungsgemäße Achszapfenhalterung diese Substanz-Begrenzungsplatten ausschließlich mittels der Achszapfen der Rakelwalze zu positionieren. Die Begrenzungsplatten werden auf die Achszapfen aufgesteckt, so daß diese sie durchsetzen, und einerseits durch die Auftragungswalze, andererseits durch die Tragplatte in der Bewegungsrichtung ausgerichtet.While it was previously customary to store the limiting plates serving to limit the substance lying in front of the application roller in the supporting plates, the journal holder according to the invention allows these substance limiting plates to be positioned exclusively by means of the journal of the doctor roller. The boundary plates are placed on the journal so that they penetrate them and are aligned in the direction of movement on the one hand by the application roller and on the other hand by the support plate.

Vorteilhafterweise sind die seitlichen SubstanzBegrenzungsplatten mit mindestens je einem Schlitz versehen, wobei in zwei korrespondierende Schlitze eine parallel zur Auftragungswalze verlaufende Begrenzungsleiste eingesetzt bzw. eingeschoben werden kann, welche die Substanz auch vorne begrenzt.Advantageously, the lateral substance limiting plates are each provided with at least one slot, it being possible to insert or insert a limiting strip running parallel to the application roller, which also delimits the substance at the front, into two corresponding slots.

Üblicherweise wird bei Verwendung der Einrichtung im Rundschablonendruck der Tragholm für die Walze auch als Farbzufuhrrohr verwendet. Dies bedingt jedoch unter Umständen einen so großen Durchmesser des Tragholms, daß es beim Farbwechsel zu erheblichen Farbverlusten kommt. Diese können dadurch erheblich verringert werden, daß nicht der Tragholm selbst, sondern ein in diesem angeordnetes weiteres Rohr als Substanzzuführungsrohr dient. Konstruktiv wird dieser Gedanke vorzugsweise so verwirklicht, daß im Tragholm ein Substanzzuführungsrohr angeordnet ist, dessen Austrittsöffnungen in Öffnungen des Tragholms münden, wobei vorzugsweise das Zuführungsrohr entlang der Öffnungen des Tragholms mit diesem verschweißt sein kann.Usually, when using the device in circular stencil printing, the spar for the roller is also used as an ink supply tube. However, this may require such a large diameter of the support beam that there is considerable loss of color when changing colors. This can significantly reduce this be that not the support beam itself, but a further tube arranged in this serves as a substance supply tube. In terms of construction, this idea is preferably realized in such a way that a substance feed pipe is arranged in the carrying beam, the outlet openings of which open into openings in the carrying beam, wherein the supply pipe can preferably be welded to the carrying beam along the openings.

Fig. 1 zeigt die für die Erfindung wesentlichen Teile einer Siebdruckmaschine für den Rundschablonendruck. Im Inneren einer Rundschablone 16 ist dabei eine Auftragungswalze 6 angeordnet, welche durch einen nicht dargestellten, unterhalb eines Drucktuches 18 angeordneten Magneten an das Innere der Rundschablone 16 angepreßt wird, wodurch vor die Auftragungswalze 6 gelangende Substanz in die zu bedruckende Warenbahn 17 gepreßt wird.1 shows the parts of a screen printing machine for circular stencil printing that are essential for the invention. In the interior of a circular stencil 16, an application roller 6 is arranged, which is pressed against the inside of the circular stencil 16 by a magnet (not shown) arranged below a printing blanket 18, whereby substance in front of the application roller 6 is pressed into the web 17 to be printed.

Die Lage der Auftragungswalze 6 wird an sich durch den unterhalb des Drucktuches 18 angeordneten Magneten bestimmt, so daß eine Lagerung im eigentlichen Sinn nicht erforderlich ist. Ausnehmungen 9 in Tragplatten 8 und 8′, die beiderseits der Auftragungswalze 6 angeordnet sind, dienen daher nur als eine Art Käfig für Achszapfen 7 der Auftragungswalze 6 und haben insbesondere den Zweck, ein Ausheben der Auftragungswalze 6 aus dem Inneren der Rundschablone 16 zu ermöglichen. Zwecks Einführung der Achszapfen 7 münden die Ausnehmungen 9 horizontal in den hand der Tragplatten 8, 8′. Ein zu weites Ausweichen der Auftragungswalze 6 in Horizontalrichtung (beispielswelse bei Abschaltung des Magnetfeldes) wird durch eine Vertiefung 20 in den Ausnehmungen 9 verhindert.The position of the application roller 6 is determined per se by the magnet arranged below the printing blanket 18, so that storage in the actual sense is not necessary. Recesses 9 in support plates 8 and 8 ', which are arranged on both sides of the application roller 6, therefore only serve as a type of cage for journal 7 of the application roller 6 and in particular have the purpose of allowing the application roller 6 to be lifted out of the interior of the circular template 16. For the introduction of the journal 7, the recesses 9 open horizontally in the hand of the support plates 8, 8 '. Excessive deflection of the application roller 6 in the horizontal direction (for example when the magnetic field is switched off) is prevented by a recess 20 in the recesses 9.

Um Schrägstellungen der Auftragungswalze 6 zu verhindern, sind Anlaufflächen 11 vorgesehen, welche an Verschlußplatten 10 angebracht sind. Letztere schließen die Ausnehmungen 9 in der Tragplatte 8 ab. Die Anordnung im Bereich der linksseitigen Tragplatte 8′ ist analog. Die Funktion dieser Anlaufflächen beruht darauf, daß sich eine schräggestellte Auftragungswalze 6 in Achsrichtung verschiebt und dadurch an der Anlauffläche 11 zur Anlage kommt, welche die Auftragungswalze 6 wieder normal zur Bewegungsrichtung 19 der Warenbahn 17 stellt.In order to prevent inclination of the application roller 6, contact surfaces 11 are provided, which are on closure plates 10 are attached. The latter close off the recesses 9 in the support plate 8. The arrangement in the area of the left-hand support plate 8 'is analog. The function of these contact surfaces is based on the fact that an inclined application roller 6 shifts in the axial direction and thereby comes to rest on the contact surface 11, which returns the application roller 6 to the direction of movement 19 of the web 17.

Zur seitlichen Begrenzung des von der Auftragungswalze 6 befindlichen Substanzvorrates ist beiderseits zwischen Tragplatte 8 (bzw. 8′) und Auftragungswalze 6 je eine seitliche Substanz-Begrenzungsplatte 12 angeordnet. Eine derartige Anordnung ist wesentlich einfacher als die bisher übliche Lagerung solcher Leisten an den Tragplatten selbst.For the lateral limitation of the substance supply located by the application roller 6, a lateral substance limiting plate 12 is arranged on each side between the support plate 8 (or 8 ') and the application roller 6. Such an arrangement is much simpler than the usual storage of such strips on the support plates themselves.

Durch in den Substanz-Begrenzungsplatten 12 angeordnete Schlitze 13 und 14 ist es möglich, wahlweise in zwei verschiedenen Lagen eine vordere Substanz-Begrenzungsleiste 15 einzuschieben, welche den vor der Auftragungswalze 6 liegenden Substanzvorrat begrenzt.By means of slots 13 and 14 arranged in the substance delimitation plates 12, it is possible to optionally insert a front substance delimitation strip 15 in two different positions, which delimits the substance supply lying in front of the application roller 6.

Befestigt sind die Tragplatten 8, 8′ beiderseits der Auftragungswalze 6 an einem rohrförmigen Tragholm 1. Um das Volumen der bei einem Substanzwechsel übrigbleibenden Drucksubstanz möglichst gering zu halten, erfolgt deren Zufuhr nicht unmittelbar durch den Tragholm 1, sondern durch ein in diesem angeordnetes Zuführungsrohr 2 geringeren Durchmessers. Die Substanz gelangt durch Austrittsöffnungen 3 im Zuführungsrohr 2 und Öffnungen 4 im Tragholm 1 auf ein Tropfblech 5 und von diesem in den Bereich vor der Auftragungswalze 6. Verbunden sind Zuführungsrohr 2 und Tragholm 1 durch Schweißnähte, welche entlang des Randes der Öffnungen 4 verlaufen.The support plates 8, 8 'are fastened on both sides of the application roller 6 to a tubular support beam 1. In order to keep the volume of the pressure substance remaining during a substance change as low as possible, their supply is not carried out directly by the support beam 1, but by a feed pipe 2 arranged in it smaller diameter. The substance passes through outlet openings 3 in the feed pipe 2 and openings 4 in the support beam 1 onto a drip plate 5 and from there into the area in front of the application roller 6. The feed pipe 2 and support beam 1 are connected by welds which run along the edge of the openings 4.

Das in Fig. 3 und 4 dargestellte Ausführungsbeispiel unterscheidet sich von jenem nach Fig. 1 und 2 dadurch, daß die schrägen Anlaufflächen, welche zur Ausrichtung der Walze 6 dienen, nunmehr in Ausnehmungen 22 der Walze 6 vorgesehen sind. Die mit den Anlaufflächen 11 zusammenwirkenden Achszapfen 25 hingegen sind hier nicht an der Walze 6, sondern an den Tragplatten 8 angeordnet. Auch bei diesem Ausführungsbeispiel sind Substanzbegrenzungsplatten 24 vorgesehen, welche je ein Ende der Walze 6 gleitend umfassen, wogegen zwischen dem Ansatz der Achszapfen 25 und diesen Substanzbegrenzungsplatten 24 ausreichend Spiel besteht, um das erfindungsgemäße Zusammenwirken der Anlaufflächen 11 mit den in der Achse 23 der Walze 6 angeordneten Achszapfen 25 zu ermöglichen.The embodiment shown in FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 in that the oblique contact surfaces, which serve to align the roller 6, are now provided in recesses 22 in the roller 6. The axle journals 25 interacting with the contact surfaces 11, on the other hand, are not arranged on the roller 6, but on the support plates 8. In this exemplary embodiment too, substance limiting plates 24 are provided, each of which slidably encompass one end of the roller 6, whereas there is sufficient play between the shoulder of the journal 25 and these substance limiting plates 24 in order for the contact surfaces 11 to interact with those in the axis 23 of the roller 6 arranged axle pin 25 to enable.

Die Erfindung ist gleichermaßen zum Auftragen von Substanzen mit oder ohne Verwendung von Flach- oder Rundschablonen verwendbar bzw. geeignet.The invention is equally suitable for the application of substances with or without the use of flat or round stencils.
