Description

Siebdruckmaschinescreen printing machine

Die Erfindung betrifft eine Siebdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a screen printing machine according to the preamble of claim 1.

Die EP 1 090 752 A1 beschreibt einen Siebzylinder für eine Siebdruckmaschine. Dieser Siebzylinder ist im wesentlichen aufgebaut aus zwei Tragringen, die die axialen Enden des Siebzylinders bilden, und einem Sieb in Form eines dünnen Gewebemantels, dessen Ränder an den Tragringen befestigt sind. Die Tragringe sind drehantreibbar an Gestellen der Siebdruckmaschine gelagert.The EP 1 090 752 A1 describes a screen cylinder for a screen printing machine. This screen cylinder is essentially composed of two support rings, which form the axial ends of the screen cylinder, and a screen in the form of a thin fabric jacket, whose edges are attached to the support rings. The support rings are rotatably mounted on frames of the screen printing machine.

Wie z. B. der JP 031 21 848 A zu entnehmen ist, muß beim Auftragswechsel oder zum Ersetzen eines verschlissenen Siebes der Siebzylinder von Zeit zu Zeit aus- und eingebaut werden. Herkömmlicherweise weisen die Tragringe des Siebzylinders jeweils einen Zahnkranz oder eine gleichwertige Kopplungseinrichtung auf, die mit einem Antriebskopf eines Getriebes im Eingriff ist, um die Drehbewegung des Siebzylinders anzutreiben. Dieser Eingriff muss beim Ausbauen des Siebzylinders jeweils aufgehoben und beim Wiedereinbau wieder hergestellt werden. Dies macht den Ein- und Ausbau zeitaufwendig. Außerdem erhöht das Vorhandensein des Zahnkranzes das Gewicht der Tragringe und erschwert deren Handhabung beim Ein- und Ausbau.Such as B. the JP 031 21 848 A it can be seen, the screen cylinder must be removed and installed from time to time when changing jobs or to replace a worn screen. Conventionally, the support rings of the screen cylinder each have a sprocket or an equivalent coupling device, which is in engagement with a drive head of a transmission to drive the rotational movement of the screen cylinder. This intervention must be lifted each time removing the screen cylinder and restored when re-installing. This makes the installation and removal time consuming. In addition, the presence of the sprocket increases the weight of the support rings and makes handling difficult during installation and removal.

Die AT 382 821 B zeigt ein Rundsieb, das mittels Bajonettverschluss in einer Lagerung befestigt wird.The AT 382 821 B shows a round screen, which is fastened by means of bayonet lock in a storage.

Der Erfindung liegt die Aufgabe zugrunde, eine Siebdruckmaschine zu schaffen.The invention has for its object to provide a screen printing machine.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Bei der Siebdruckmaschine wird gewissermaßen der Tragring herkömmlicher Siebzylinder zweigeteilt, einerseits in einen drehantreibbaren Ring, der als ein Teil der Lageranordnung des Siebzylinders angesehen wird, und der nicht mehr beim Austausch des Siebzylinders entfernt werden muss, und andererseits ein Kopfstück des Siebzylinders, welches an Klauen des besagten Rings lösbar montierbar ist und lediglich noch die Funktion hat, das Sieb in der gewünschten Zylinderform aufzuspannen. Um die Montage des Siebzylinders bzw. seiner Kopfstücke an den Ringen zu vereinfachen, ist vorgesehen, dass die Klauen jedes Rings jeweils nur auf einer Hälfte von dessen Umfang platzierbar sind. So kann ein Kopfstück in einer Bewegung quer zur Achse des Siebzylinders, über die von Klauen freie Hälfte des Umfangs des Rings, in seine am Ring gehaltene Position eingeführt bzw. aus dieser entfernt werden.In the screen printing machine, so to speak, the support ring conventional screen cylinder is divided into two, on the one hand in a rotatably drivable ring, which is considered part of the bearing assembly of the screen cylinder, and no longer needs to be removed when replacing the screen cylinder, and on the other hand, a head of the screen cylinder, which on claws said ring is detachably mountable and only has the function to open the screen in the desired cylindrical shape. In order to simplify the assembly of the screen cylinder or its head pieces on the rings, it is provided that the claws of each ring can be placed only on one half of its circumference. Thus, a headpiece may be inserted into or removed from its position at a position transverse to the axis of the screen cylinder via the claw-free half of the circumference of the ring.

Einer bevorzugten Ausgestaltung zufolge, die nicht beansprucht ist, tragen die Ringe der zwei Lageranordnungen jeweils wenigstens zwei Klauen, von denen wenigstens eine aus einer Position, in der sie gemeinsam mit der wenigstens einen anderen Klaue auf einer Hälfte des Umfangs des Rings liegt, um die Achse des Siebzylinders in eine Position verdrehbar ist, in der nicht alle Klauen auf einer Hälfte des Umfangs des Rings liegen. Durch Fixieren der verdrehbaren Klaue in dieser Position wird ein sich Lösen des Kopfstücks vom Ring sicher vermieden.According to a preferred embodiment, which is not claimed, the rings of the two bearing assemblies each carry at least two jaws, at least one of which, at a position in which it lies together with the at least one other jaw on one half of the circumference of the ring The axis of the screen cylinder is rotatable to a position in which not all claws lie on one half of the circumference of the ring. By fixing the rotatable jaw in this position, a detachment of the head piece from the ring is reliably avoided.

Bei einer Ausgestaltung, die nicht beansprucht ist, mit zwei Klauen liegt die Position, in der die verdrehbare Klaue fixiert wird, in Bezug auf die Achse des Siebzylinders der anderen Klaue vorzugsweise diametral gegenüber. Allgemeiner kann man sagen, dass der Schwerpunkt der verdrehbaren ersten Klaue dem der wenigstens einen anderen, nicht verdrehbaren Klaue diametral gegenüberliegt.In one embodiment, which is not claimed with two claws, the position in which the rotatable jaw is fixed is preferably diametrically opposite with respect to the axis of the screen cylinder of the other jaw. More generally, the center of gravity of the rotatable first jaw is diametrically opposed to the at least one other non-rotatable jaw.

Einer zweiten Ausgestaltung zufolge weist der Ring lediglich eine einzige Klaue oder mehrere Klauen auf, die jedoch relativ zu einander unbeweglich sind. Um in diesem Fall einen sicheren Halt des Kopfstücks an dem Ring zu erzielen, ist es notwendig, dass zwei seitliche Ränder der Klauen in Bezug auf die Achse einen Winkel von 180°einschließen. Ein sicherer Halt des Kopfstücks an dem Ring kann bei dieser Ausgestaltung insbesondere dadurch erreicht werden, dass die Klaue oder Klauen jeweils eine für den Kontakt mit dem Kopfstück vorgesehene Innenfläche aufweist/aufweisen, die auf einem um die Achse des Siebzylinders zentrierten Kegel liegt, wobei der Scheitel des Kegels auf derjenigen Seite der die Klauen aufweisenden Lageranordnung liegt, die von der jeweils anderen Lageranordnung abgewandt ist.According to a second embodiment, the ring has only a single jaw or a plurality of jaws, which, however, are immovable relative to one another. In order to achieve a secure hold of the head piece on the ring in this case, it is necessary that two lateral edges of the claws make an angle of 180 ° with respect to the axis. A secure hold of the head piece on the ring can be achieved in this embodiment, in particular by the fact that the claw or jaw each have / has an intended for contact with the head inner surface / which lies on a centered about the axis of the screen cylinder cone, wherein the Vertex of the cone on the side of the claw bearing assembly is facing away from the other bearing assembly.

An den Klauen des Rings wenigstens einer Lageranordnung können Federelemente vorgesehen sein, die auf ein an den Klauen montiertes Kopfstück eine von der jeweils anderen Lageranordnung fort orientierte axiale Kraft ausüben. Diese Federelemente können unterschiedlichen Aufgaben dienen.On the claws of the ring of at least one bearing arrangement spring elements may be provided which exert on a claw mounted on the head piece from the other bearing arrangement fort oriented axial force. These spring elements can serve different tasks.

Zum einen kann die Siebdruckmaschine so ausgelegt sein, dass in ihrem Betrieb die Federelemente einen Spalt zwischen dem Kopfstück und den Innenflächen der Halteklauen offen halten. Die axiale Spannung, unter der das Sieb steht, ist in einem solchen Fall festgelegt durch die Kraft der Federelemente, und ist durch Justieren der axialen Position der Ringe in gewissen Grenzen einstellbar. Der Vorteil dieser Konstruktion liegt darin, dass wenn ein axialer Schlag die Kopfstücke kurzzeitig auseinander treibt oder eine radial auf das Sieb einwirkende Kraft dessen Spannung in axialer Richtung erhöht, die Federn nachgeben und so die Siebspannung begrenzen und ein Reißen des Siebes verhindern können.First, the screen printing machine can be designed so that in their operation, the spring elements keep a gap between the head piece and the inner surfaces of the retaining claws open. The axial tension under which the screen is, is determined in such a case by the force of the spring elements, and is adjustable by adjusting the axial position of the rings within certain limits. The advantage of this design is that when an axial impact momentarily forces the head pieces apart or a force acting radially on the wire increases its tension in the axial direction, the springs yield, thus limiting the wire tension and preventing tearing of the wire.

Es kann jedoch auch vorgesehen werden, dass im Betrieb der Siebdruckmaschine die Innenflächen der Klauen den Flansch berühren, etwa um ihn einzuklemmen und festzuhalten. In einem solchen Falle können die Federelemente dazu dienen, beim Ausbau des Siebzylinders dessen Kopfstücke wieder von den Halteklauen zu lösen. Dies kann insbesondere nötig sein, wenn durch im Laufe des Betriebs angesammelte Farbreste das Kopfstück an den Klauen festklebt.However, it may also be provided that in operation of the screen printing machine, the inner surfaces of the jaws touch the flange, about to pinch it and hold. In such a case, the spring elements can serve, during Removal of the screen cylinder whose head pieces to release again from the retaining claws. This may be necessary, in particular, if the ink residue sticks to the claws during the course of operation.

Ein Kopfstück für einen Siebzylinder weist einen zylindrischen Trägerabschnitt zur Befestigung eines Siebes und einen mit dem Trägerabschnitt verbundenen, in radialer Richtung vorspringenden Flansch auf, an welchem die Klauen angreifen können.A head piece for a screen cylinder has a cylindrical support portion for attaching a screen and a radially projecting flange connected to the support portion to which the jaws can engage.

Um eine Drehantriebskraft vom Ring auf das Kopfstück übertragen zu können, weist dessen Flansch vorzugsweise einen unrunden radialen Querschnitt auf, insbesondere in Form von zwei in Umfangsrichtung aufeinanderfolgenden Abschnitten mit unterschiedlicher radialer Breite. Die Ausdehnung dieser Abschnitte in Umfangsrichtung ist vorzugsweise so bemessen, dass radial orientierte Oberflächen, die die Abschnitte unterschiedlicher radialer Breite des Flansches voneinander trennen, an jeweils einem seitlichen Rand einer Klaue anliegen.In order to be able to transmit a rotational drive force from the ring to the head piece, its flange preferably has a non-circular radial cross-section, in particular in the form of two successive sections of different radial width in the circumferential direction. The extent of these sections in the circumferential direction is preferably dimensioned so that radially oriented surfaces which separate the sections of different radial width of the flange from each other, abut against a respective lateral edge of a claw.

Fig. 1 shows a partial perspective view of a screen printing machine according to a first embodiment which is not claimed. It can be seen a screen cylinder 01, held by two bearing assemblies 02; 03, which are each mounted on frames only partially shown 04 of the screen printing machine. A likewise connected to the racks 04, fixedly mounted within the screen cylinder 01 doctor blade is not shown for clarity.

Der Aufbau der Lageranordnungen 02; 03 und des Siebzylinders 01 wird insbesondere mit Bezug auf Fig. 2 erläutert. Jede Lageranordnung 02; 03 umfasst einen mit dem jeweiligen Gestell 04 fest verbundenen, hohlzylindrischen Schaft 06, an welchem ein Ring 07 über ein Lager 08, z. B. ein Nadellager 08 drehbar montiert ist. Ein äußerer Zahnkranz 09 jedes Rings 07 ist auf einem Großteil seines Umfangs von einer fest mit dem benachbarten Gestell 04 verbundenen Hülse umgeben. Ein in Fig. 1 gezeigtes Fenster 10 der Hülse erlaubt den Eingriff eines Zahnrades 11 in den Zahnkranz 09 der Lageranordnungen 02, 03. Die Zahnräder 11 an beiden Seiten der Siebdruckmaschine sind über ein nicht dargestelltes Getriebe durch einen Antriebsmotor mit gleichen Geschwindigkeiten antreibbar.The structure of the bearing assemblies 02; 03 and the screen cylinder 01 is in particular with reference to Fig. 2 explained. Each bearing assembly 02; 03 includes a fixedly connected to the respective frame 04, hollow cylindrical shaft 06, on which a ring 07 via a bearing 08, z. B. a needle bearing 08 is rotatably mounted. An outer ring gear 09 of each ring 07 is surrounded on a large part of its circumference by a fixedly connected to the adjacent frame 04 sleeve. An in Fig. 1 shown window 10 of the sleeve allows the engagement of a gear 11 in the ring gear 09 of the bearing assemblies 02, 03. The gears 11 on both sides of the screen printing machine can be driven by a drive motor at the same speeds via a not shown gear.

Der Ring 07 ist aufgebaut aus zwei konzentrischen Teilringen12; 13, einem inneren Teilring 12, der den Zahnkranz 09 und eine später noch genauer erläuterte erste Klaue 13 trägt, sowie einem äußeren Teilring 14, der um den inneren Teilring 12 herum drehbar ist und eine zweite Klaue 16 trägt. Im Schnitt der Fig. 2 sowie der perspektivischen Ansicht der Fig. 4 sind diese zwei Klauen 13; 16 einander diametral gegenüberliegend dargestellt. In dieser Stellung ist der äußere Teilring 14 in Bezug auf den inneren Teilring 12 durch eine Federkapsel 17 drehfixiert, die in den inneren Teilring 12 eingelassen ist und eine Kugel 18 in eine Aussparung an der dem inneren Teilring 12 zugewandten Innenseite des äußeren Teilrings 14 drückt.The ring 07 is composed of two concentric partial rings 12; 13, an inner partial ring 12, which carries the ring gear 09 and a later explained in more detail first jaw 13, and an outer partial ring 14 which is rotatable about the inner partial ring 12 around and a second claw 16 carries. On average, the Fig. 2 as well as the perspective view of Fig. 4 these two claws 13; 16 shown diametrically opposite each other. In this position, the outer part ring 14 is rotationally fixed with respect to the inner part ring 12 by a spring capsule 17, which is embedded in the inner part ring 12 and a ball 18 in a recess on the inner part of the ring 12 facing inside of the outer part ring 14 suppressed.

Die zwei Klauen 13; 16 haben jeweils einen sich parallel zur Achse des Siebzylinders 01 erstreckenden Stielabschnitt 19; 21 und einen sich vom freien Ende des Stielabschnitts 19 bzw. 21 radial zur Achse des Siebzylinders 01 hin erstreckenden Kopfabschnitt 22 bzw. 23.The two claws 13; 16 each have a parallel to the axis of the screen cylinder 01 extending stem portion 19; 21 and a from the free end of the stem portion 19 and 21 radially to the axis of the screen cylinder 01 extending towards the head portion 22 and 23rd

Wie die perspektivische Ansicht der Fig. 4 zeigt, erstreckt sich der Stielabschnitt 19 der ersten Klaue 13 halbkreisförmig über die Hälfte des Umfangs des Rings 07. Der Kopfabschnitt 22 der ersten Klaue 13 ist demgegenüber kürzer. An einer dem Betrachter in Fig. 4 zugewandten Seite 24 der ersten Klaue 13 sind Stielabschnitt 19 und Kopfabschnitt 22 bündig, an der gegenüberliegenden Seite 26 endet der Kopfabschnitt 22 ca. 30°früher als der Stielabschnitt 19.Like the perspective view of the Fig. 4 shows, the stem portion 19 of the first jaw 13 extends semicircular over half of the circumference of the ring 07. The head portion 22 of the first jaw 13 is in contrast shorter. At one the viewer in Fig. 4 facing side 24 of the first jaw 13 are stem portion 19 and head portion 22 flush, on the opposite side 26 of the head portion 22 ends 30 ° earlier than the stem portion 19th

Die drehbare zweite Klaue 16 erstreckt sich ihrerseits über ca. 30°des Ringsumfangs. Sie ist aus der in Fig. 4 gezeigten Position in eine Position verdrehbar, in der ihr Kopfabschnitt 23 die Seite 26 des Kopfabschnitts 22 berührt, so dass sich beide Klauen 13, 16 gemeinsam über exakt die Hälfte des Umfangs des Rings 07 erstrecken.The rotatable second jaw 16 in turn extends over approximately 30 ° of the circumference of the ring. She is from the in Fig. 4 rotated position shown in a position in which its head portion 23, the side 26 of the head portion 22 contacts, so that both jaws 13, 16 together extend over exactly half of the circumference of the ring 07.

In dieser Stellung der Klauen 13; 16 ist die Montage des Siebzylinders 01 möglich.In this position, the claws 13; 16, the assembly of the screen cylinder 01 is possible.

Der Siebzylinder 01 umfasst, wie in Fig. 1 zu erkennen, zwei Kopfstücke 27, die jeweils zur Montage an den Lageranordnungen 02; 03 vorgesehen sind, sowie ein von den Kopfstücken 27 zylinderförmig aufgespanntes Sieb 28. Wie man in Fig. 2 erkennt, ist dieses Kopfstück 27 einteilig aufgebaut aus einem zylindrischen Trägerabschnitt 29, dessen Außenfläche vorgesehen ist, um daran das Sieb 28 in an sich bekannter Weise zu befestigen, und einem radial vorspringenden Flansch 31, die miteinander durch einen Übergangsabschnitt 32 mit jeweils kleinerem Außendurchmesser als dem des Trägerabschnitts 29 bzw. des Flansches 31 verbunden sind.The screen cylinder 01 comprises, as in Fig. 1 to recognize two head pieces 27, each for mounting on the bearing assemblies 02; 03 are provided, and one of the head pieces 27 cylinder-shaped strained screen 28. As in Fig. 2 recognizes is this head piece 27 is integrally composed of a cylindrical support portion 29, the outer surface is provided to fasten the screen 28 in a conventional manner, and a radially projecting flange 31, which together by a transition portion 32 having a smaller outer diameter than that of the support portion 29 and the flange 31 are connected.

Fig. 3 zeigt eine perspektivische Teilansicht des Siebzylinders 01 mit einem Kopfstück 27. Der Flansch 31 des Kopfstücks 27 weist zwei in Umfangsrichtung von einander durch radial orientierte Oberflächen 33 abgesetzte Abschnitte 34; 36 mit unterschiedlichen Radien auf. Jeder Abschnitt 34; 36 erstreckt sich hier über die Hälfte des Umfangs des Flansches 31. Der Radius des Abschnitts 34 mit kleinerem Radius entspricht dem Innenradius des Stielabschnitts 19, der des Abschnitts 36 mit größerem Radius dem Außenradius des Stielabschnitts 19 oder, was vorzugsweise bis auf ein geringes Spiel dasselbe ist, dem Innenradius des Stielabschnitts 21. Wenn sich die zweite Klaue 16 in ihrer oben beschriebenen Position neben der ersten Klaue 13 befindet, ist der so geformte Flansch 31 bequem in einer Bewegung quer zur Achse des Siebzylinders 01 in die Lageranordnung 02 bzw. 03 einführbar. Beim Einführen kommen die radial orientierten Oberflächen 33 in Kontakt mit den Seiten des Stielabschnitts 21. Durch Drehen des äußeren Teilrings 14 gelangt dessen Klaue 16 in die in Fig. 4 bzw. 5 gezeigte Stellung, in der sie der Klaue 13 diametral gegenüber liegt. So wird das Kopfstück 27, wie in Fig. 5 gezeigt, an der Lageranordnung 03 fixiert. Dabei sind die radial orientierten Oberflächen 33 des Flansches 31 jeweils in Kontakt mit den Rändern des Stielabschnitts 19 der ersten Klaue 13, so dass eine Drehung des Rings 07 exakt auf den Siebzylinder 01 übertragen wird. Fig. 3 shows a partial perspective view of the screen cylinder 01 with a head piece 27. The flange 31 of the head piece 27 has two circumferentially offset from each other by radially oriented surfaces 33 sections 34; 36 with different radii. Each section 34; Here, the radius of the smaller radius portion 34 corresponds to the inner radius of the stem portion 19, that of the larger radius portion 36 to the outer radius of the stem portion 19 or, which is preferably the same except for a small clearance When the second jaw 16 is in its above-described position adjacent to the first jaw 13, the thus formed flange 31 is conveniently insertable in a movement transverse to the axis of the screen cylinder 01 into the bearing assembly 02 and 03, respectively , When inserting the radially oriented surfaces 33 come into contact with the sides of the stem portion 21. By turning the outer part ring 14 reaches the claw 16 in the in Fig. 4 or 5 shown position in which it is the claw 13 diametrically opposite. So the head piece 27, as in Fig. 5 shown fixed to the bearing assembly 03. In this case, the radially oriented surfaces 33 of the flange 31 are respectively in contact with the edges of the stem portion 19 of the first jaw 13, so that a rotation of the ring 07 is exactly transferred to the screen cylinder 01.

Um das Sieb 28 des auf diese Weise an den Lageranordnungen 02, 03 montierten Siebzylinders 01 zu straffen, ist die Lageranordnung 03 mit drei Linearstellgliedern 37 in Form von eines Arbeitszylinders, z. B. eines Pneumatik- oder Hydraulikzylinders ausgestattet, die in der Lage sind, den Ring 07 in axialer Richtung zu verschieben. Diese Linearstellglieder 37 werden betätigt, um den Ring 07 der Lageranordnung 03 in Richtung der gegenüberliegenden Lageranordnung 02 zu verschieben und so das Sieb 28 zu entspannen, wenn der Siebzylinder 01 demontiert werden soll. Nach der Montage eines Siebzylinders 01 ziehen die Linearstellglieder 37 den Ring 07 in die entgegengesetzte Richtung, um das Sieb 28 zu straffen.In order to tighten the wire 28 of the screen cylinder 01 mounted in this way on the bearing assemblies 02, 03, the bearing assembly 03 with three linear actuators 37 in the form of a working cylinder, for. B. a pneumatic or hydraulic cylinder equipped, which are able to move the ring 07 in the axial direction. These Linear actuators 37 are actuated to move the ring 07 of the bearing assembly 03 in the direction of the opposite bearing assembly 02 and so to relax the wire 28 when the screen cylinder 01 is to be dismantled. After mounting a screen cylinder 01, the linear actuators 37 pull the ring 07 in the opposite direction to tighten the screen 28.

Wie man in Fig. 5 erkennen kann, besteht ein geringer Spalt 38 zwischen einer dem Ring 07 zugewandten, sich radial erstreckenden Innenseite 39 der Kopfabschnitte 22; 23 der Klauen 13; 16 und einer dieser Innenseite zugewandten Oberfläche des Flansches 31. Dieser Spalt 38 ist offen gehalten von in die Kopfabschnitte 22 bzw. 23 eingelassenen Federelement 41, z. B. Druckfedern 41, wie in Fig. 2 und 4 gezeigt. Diese Druckfedern 41 ermöglichen es, beim Straffen des Siebs 28 einen vorgegebenen Spannungswert einzustellen, und ihre Nachgiebigkeit hilft, Überschreitungen einer kritischen Spannung im Betrieb, die zu einer Beschädigung des Siebs führen könnte, zu vermeiden, sowie einen Ausgleich von Axialschlag der Flansche 31.How to get in Fig. 5 can recognize, there is a small gap 38 between the ring 07 facing radially extending inside 39 of the head portions 22; 23 of the claws 13; 16 and one of these inner side facing surface of the flange 31. This gap 38 is kept open by in the head portions 22 and 23 embedded spring element 41, z. B. compression springs 41, as in Fig. 2 and 4 shown. These compression springs 41 make it possible to set a predetermined tension value when tightening the screen 28, and their resilience helps to avoid exceeding a critical tension in operation, which could lead to damage of the screen, as well as a compensation of axial deflection of the flanges 31st

Eine alternative Ausgestaltung der Erfindung ist anhand der Fig. 6 und 7 dargestellt, die jeweils Ansichten analog zu den Fig. 2 bzw. 4 darstellen. Elemente dieser zweiten Ausgestaltung, die bereits zuvor beschriebenen entsprechen, tragen gleiche Bezugszeichen und werden nicht erneut beschrieben. Diese zweite Ausgestaltung unterscheidet sich von der ersten darin, dass der Ring 07 jeder Lageranordnung 02; 03 einteilig ist und eine einzige Klaue 42 trägt, die sich über einen Winkel von 180°um die Achse des Siebzylinders 01 erstreckt. Eine dem Ring 07 zugewandte Innenfläche 43 der Klaue 42 ist kegelförmig, wobei der Scheitel des Kegels von der jeweils gegenüberliegenden Lageranordnung 02; 03 abgewandt ist. Komplementär zur Gestalt der Innenfläche 43 weist der Flansch 31 ebenfalls eine kegelförmige Oberfläche auf.An alternative embodiment of the invention is based on Fig. 6 and 7 shown, each with views analogous to the Fig. 2 or 4 represent. Elements of this second embodiment, which are already described above, bear like reference numerals and will not be described again. This second embodiment differs from the first in that the ring 07 of each bearing assembly 02; 03 is one piece and carries a single claw 42 which extends over an angle of 180 ° about the axis of the screen cylinder 01. An annular surface 07 facing the inner surface 43 of the claw 42 is conical, the apex of the cone of the respective opposite bearing assembly 02; 03 is turned away. Complementary to the shape of the inner surface 43, the flange 31 also has a conical surface.

Auch hier hat der Flansch 31 zwei Abschnitte mit unterschiedlichem Radius, die durch im montierten Zustand durch die Seiten 24; 26 der Klaue 42 berührende radiale Oberflächen verbunden sind, um eine exakte Übertragung der Drehbewegung des Rings 07 auf den Siebzylinder 01 zu gewährleisten.Again, the flange 31 has two sections of different radius, which in the assembled state by the sides 24; 26 of the claw 42 contacting radial surfaces are connected to ensure an accurate transmission of the rotational movement of the ring 07 on the screen cylinder 01.

Wenn die Linearstellglieder 37 betätigt werden, um zur Vorbereitung des Betriebs der Siebdruckmaschine das Sieb 28 zu spannen, kommt die Innenfläche 43 der Klaue 42 in innigen Kontakt mit dem Flansch 31. Die Kegelform der Innenfläche 43 und der ihr zugewandten Oberfläche des Flansches 31 bewirkt dabei, dass entlang der Innenfläche 43 eine radial nach außen gerichtete Kraft auf den Flansch 31 wirkt, die ein Entweichen des Flansches 31 aus der Klaue 42 verhindert.When the linear actuators 37 are actuated to tension the wire 28 to prepare for operation of the screen printing machine, the inner surface 43 of the pawl 42 comes into intimate contact with the flange 31. The conical shape of the inner surface 43 and the surface of the flange 31 facing it effect in that a radially outwardly directed force acts on the flange 31 along the inner surface 43, which prevents the flange 31 from escaping from the claw 42.

In die Klaue 42 eingelassene Federelement 44, z. B. Druckfedern 44 sind vorgesehen, um wenn für die Demontage des Siebzylinders 01 das Sieb 28 entspannt wird, den Kontakt zwischen der Innenfläche 43 und dem Flansch 31 zu lösen und so die Entnahme des Kopfstücks aus der Lageranordnung 02; 03 zu erleichtern.In the claw 42 recessed spring element 44, z. B. compression springs 44 are provided to when the sieve 28 is relaxed for the disassembly of the screen cylinder 01, the contact between the inner surface 43 and the flange 31 to solve and so the removal of the head piece from the bearing assembly 02; 03 to facilitate.

Bei den oben beschriebenen Ausgestaltungen ist davon ausgegangen worden, dass jeder Ring bzw. Teilring nur eine Klaue 13; 16 oder 42 trägt. Es liegt jedoch auf der Hand, dass die Zahl der Klauen im Prinzip beliebig sein kann, so lange alle Klauen in einem Winkelbereich von 180°Platz finden, so dass sie di e seitliche Einführung eines Kopfstücks in die Lageranordnungen 02; 03 nicht behindern.In the embodiments described above, it has been assumed that each ring or partial ring only one jaw 13; 16 or 42 carries. However, it is obvious that the number of claws in principle can be arbitrary, as long as all claws find in an angular range of 180 ° place so that they di e lateral insertion of a head piece in the bearing assemblies 02; 03 does not hinder.
