Description

Die Erfindung betrifft eine Vorrichtung zum Einführen eines eine Druckwalze tragenden Einschubwagens in eine Druckmaschine.The invention relates to a device for inserting a push-in carriage carrying a printing roller into a printing press.

Einschubwagen dieser Art werden üblicherweise verwendet, um Druckwalzen derart zwischen die Seitengestelle einer Druck­maschine einzuführen, daß die Wellenzapfen in Langlöcher oder Aussparungen der Seitengestelle greifen, in denen diese dann mit den Zapfenlagern verbindbar sind. In entsprechender Weise dienen die Einschubwagen zur Entnahme von Druckwalzen aus einer Druck­maschine nach dem Lösen von deren Wellenzapfen von den Zapfen­lagern, wie dies beispielsweise bei einem Wechsel von Druck­walzen erforderlich ist. Die Handhabung der Einschubwagen mit aufgelegter Druckwalze zu deren Einführen oder deren Austragen erfordert ein großes Geschick des Bedienungspersonals, das Kolli­sionen des Einschubwagens und der Wellenzapfen der Druckwalze mit den Seitengestellen oder anderen Teilen der Druckmaschine verhindern muß, um Beschädigungen durch entsprechende Stoß­beanspruchungen zu verhindern. Die Praxis zeigt, daß trotz großer Aufmerksamkeit der Bedienungspersonen leichtere und auch schwerere Kollisionen des Einschubwagens und der Wellenzapfen der Druckwalze mit Teilen der Druckmaschine nicht immer vermieden werden können.Insert trolleys of this type are usually used to insert pressure rollers between the side frames of a printing press in such a way that the shaft journals engage in elongated holes or recesses in the side frames, in which these can then be connected to the journal bearings. In a corresponding manner, the slide-in carriages are used to remove printing rollers from a printing press after their shaft journals have been released from the journal bearings, as is necessary, for example, when changing printing rollers. The handling of the slide-in carriage with the pressure roller placed on it for the insertion or discharge thereof requires a great deal of skill on the part of the operating personnel, who must prevent the slide-in carriage and the shaft journals of the pressure roller from colliding with the side frames or other parts of the printing press in order to prevent damage from corresponding impact loads. Practice shows that despite great attention from the operators, lighter and also more serious collisions of the insert carriage and the shaft journal of the printing roller with parts of the printing machine cannot always be avoided.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, mit der sich ein eine Druckwalze tragender Einschubwagen zum Einführen der Druckwalze in das Druckmaschinengestell hineinfahren und zu deren Entnahme wieder herausfahren läßt, ohne daß zu Beschädigungen führende Kollisionen des Einschubwagens oder der Druckwalze mit Teilen der Druckmaschine zu befürchten sind.The object of the invention is therefore to provide a device of the type specified at the beginning, with which a push-in carriage carrying a printing roller can be inserted into the printing press frame for insertion of the printing roller and can be removed for removal therefrom without collisions of the push-in carriage leading to damage or Printing roller with parts of the printing machine are to be feared.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß der Einschubwagen mit zwei Gleitsteinen oder mit zwei um vertikale Achsen drehbar gelagerten Führungsrollen versehen ist, die in eine Längsnut einer Führungsschiene einschiebbar sind, die zwischen einer ausgeschwenkten Einschubstellung für den Einschubwagen und einer eingeschwenkten Stellung verschwenkbar ist, in der die Wellen­zapfen der Druckwalze in Ausnehmungen der Seitenteile des Druck­maschinengestells greifen, in denen diese mit den Zapfenlagern verbindbar sind. Die erfindungsgemäße Vorrichtung verhindert mit Sicherheit zu Beschädigungen führende Kollisionen des Einschub­wagens und der Druckwalze mit Teilen der Druckmaschine. Die Bedienungsperson braucht lediglich in der ausgeschwenkten Stellung der Führungsschiene die Gleitsteine oder Führungsrollen in deren Längsnut einzuschieben, was ohne Kollisionsgefahr möglich ist, weil sich keine Maschinenteile im Bereich der ausgeschwenkten Führungsschiene befinden. Wird nun nach dem Einschieben der Gleitsteine oder Führungsrollen des Einschub­wagens in die Längsnut der Führungsschiene diese in die Druck­maschine hineingeschwenkt, übernimmt diese die Führung des Einschubwagens, so daß dieser zwangsweise ohne Kollisionen mit Teilen der Druckmaschine in eine Lage geführt wird, in der sich die Wellenzapfen der Druckwalze in den Ausnehmungen der Seitenteile des Druckmaschinengestells in der Weise befinden, daß diese in bekannter und daher hier nicht näher beschriebener Weise mit den Zapfenlagern verbunden werden können. In entsprechender Weise lassen sich kollisionsfrei Druckwalzen aus der Druckmaschine herausführen. Der in der Führungsschiene gehalterte Einschubwagen kann während des Druckbetriebes in seiner in die Druckmaschine eingefahrenen Stellung verbleiben, so daß er sich zum Zwecke der späteren Entnahme der Druckwalze bereits in der richtigen Stellung befindet.According to the invention, this object is achieved in a device of the generic type in that the slide-in carriage is provided with two sliding blocks or with two guide rollers rotatably mounted about vertical axes, which can be pushed into a longitudinal groove of a guide rail, which is between a pivoted-out slide-in position for the slide-in carriage and one pivoted position is pivotable, in which the shaft journals of the printing roller engage in recesses in the side parts of the printing press frame, in which they can be connected to the journal bearings. The device according to the invention certainly prevents collisions of the slide-in carriage and the printing roller with parts of the printing machine which lead to damage. The operator only needs to slide the sliding blocks or guide rollers into their longitudinal groove in the pivoted-out position of the guide rail, which is possible without risk of collision because there are no machine parts in the region of the pivoted-out guide rail. If the sliding blocks or guide rollers of the slide-in carriage are now pivoted into the longitudinal groove of the guide rail into the printing press, this takes over the guidance of the slide-in carriage so that it is forced into a position in which the shaft journals are located without collisions with parts of the printing press the pressure roller in the recesses of the Lateral parts of the printing press frame are located in such a way that they can be connected to the journal bearings in a known and therefore not described in detail here. Correspondingly, printing rollers can be guided out of the printing machine without collision. The slide-in carriage held in the guide rail can remain in its position retracted into the printing press during the printing operation, so that it is already in the correct position for the purpose of later removal of the printing roller.

Zweckmäßigerweise ist der Einschubwagen mit an seinem Grundrahmen befestigten, dessen eine Längsseite überkragenden Hebeln versehen, die an den unteren freien Enden von vertikalen Achszapfen die Gleitsteine oder Führungsrollen tragen.Advantageously, the slide-in cart is fastened to its base frame, the one side of which protrudes over its levers and which carry the sliding blocks or guide rollers at the lower free ends of vertical axle journals.

Zweckmäßigerweise ist der Einschubwagen mit vier Rädern versehen, die in gabelförmigen, um vertikale Achsen frei drehbaren Lagerböcken gelagert sind, wobei die Drehachsen der Räder jeweils einen Abstand von der vertikalen Achse aufweisen (sogenannte Teewagenräder).The insertion trolley is expediently provided with four wheels which are mounted in fork-shaped bearing blocks which are freely rotatable about vertical axes, the axes of rotation of the wheels being at a distance from the vertical axis (so-called tea trolley wheels).

Der Einschubwagen kann im Abstand voneinander mit V-förmigen Böcken zur Aufnahme der Achszapfen einer Druckwalze versehen sein, von denen jeweils eine Flanke zur Freigabe der Druckwalze abklappbar ist. Weiterhin können die Aufnahmen in ihrem relativen Abstand zueinander verstellbar sein.The slide-in trolley can be provided at a distance from one another with V-shaped trestles for receiving the axle journals of a pressure roller, one flank of which can be folded down to release the pressure roller. Furthermore, the relative spacing of the recordings can be adjustable.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß der Einschubwagen und/oder das Druckmaschinengestell mit um vertikale Achsen drehbaren Rollen versehen ist, die begrenzende Anschläge bilden. Beim Einschieben der Führungsrollen des Einschubwagens in die Längsnut der ausgeschwenkten Führungs­schiene wird dann der Einschubwagen so weit in der Längsnnut vorgeschoben, bis er mit seinen Rollen auf entsprechende Gleitflächen eines Seitenteils trifft oder bis sich an einem Seitenteil befindliche Führungsrollen auf Rahmenteilen des Einschubwagens abstützen. Beim Einschwenken übernehmen diese Rollen zusätzlich eine Führung und gewährleisten ein reibungs­armes Einschieben.In a further embodiment of the invention it is provided that the slide-in carriage and / or the printing machine frame is provided with rollers which can be rotated about vertical axes and which form limiting stops. When the guide rollers of the slide-in carriage are inserted into the longitudinal groove of the swiveled-out guide rail, the slide-in carriage is then pushed forward in the longitudinal groove until it rolls with its corresponding rollers Sliding surfaces of a side part meet or until guide rollers located on a side part are supported on frame parts of the slide-in carriage. When swiveling in, these roles also take over a guide and ensure a low-friction insertion.

Nach einer besonders vorteilhaften Ausgestaltung ist vorgesehen, daß die Führungsschiene mit dem Druckmaschinengestell durch zwei Lenker gelenkig verbunden ist. Diese Lenker weisen vorzugsweise in der Weise unterschiedliche Längen auf, daß diese die Führungs­schiene zwischen ihrer eingeschwenkten Stellung, in der diese rechtwinkelig zu den Seitengestellen der Druckmaschine steht, und ihrer winkeligen ausgeschwenkten Stellung führen, in der die Führungsrollen der Gleitsteine in die Führungsnut einschiebbar sind.According to a particularly advantageous embodiment, it is provided that the guide rail is articulated to the printing machine frame by two links. These links preferably have different lengths in such a way that they guide the guide rail between its pivoted-in position, in which it is at right angles to the side frames of the printing press, and its angular, pivoted-out position, in which the guide rollers of the sliding blocks can be inserted into the guide groove.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß ein Antrieb zum Verschwenken der Führungsschiene vorgesehen ist. Dieser Schwenkantrieb erleichtert das lagerichtige Einführen und Herausfahren weiterhin dadurch, daß die Bedienungspersonen den Einschubwagen lediglich in die ausgeschwenkte Führungsschiene einschieben müssen. Die nachfolgende Einschwenkbewegung kann sodann selbsttätig erfolgen, wobei die Bedienungsperson lediglich darauf achten muß, daß während des Verschwenkens der Führungsschiene der Einschubwagen vollständig in der Längsnut eingeschoben bleibt. Zweckmäßigerweise besteht der Antrieb aus einer Druckmittel-Kolben-Zylinder-Einheit, die einerseits in einem Lenker und andererseits an dem Druckmaschinengestell angelenkt ist.In a further embodiment of the invention it is provided that a drive is provided for pivoting the guide rail. This swivel drive further facilitates the correct insertion and removal in that the operators only have to insert the insert carriage into the swiveled-out guide rail. The subsequent swiveling-in movement can then take place automatically, the operator merely having to take care that the insert carriage remains fully inserted in the longitudinal groove during the swiveling of the guide rail. The drive expediently consists of a pressure medium piston-cylinder unit which is articulated on the one hand in a link and on the other hand on the printing press frame.

An embodiment of the invention is explained below with reference to the drawing. In this shows
  • 1 shows a schematic front view of a printing press Illustration with slide-in cart,
  • 2 shows a longitudinal section through the printing press and the slide-in carriage along the line II-II in FIG. 1,

Die beiden Seitengestelle 1 einer Druckmaschine sind durch ein Hohlprofil 2 miteinander verbunden. Das Hohlprofil 2 trägt an beiden Enden je einen nach oben weisenden Tragarm 3, wobei diese zum Teil in die Seitengestelle 1 eingelassen sind. In bekannter Weise sind die Seitengestelle 1 mit die Walzenzapfen 4 auf­nehmenden Langlöchern versehen, wobei auch die Tragarme maul­artige Aufnahmeausnehmungen 6 aufweisen. Auf die Ausbildung der Einrichtungen mittels denen die Lagerzapfen 4 in den Langlöchern 5 und den Ausnehmungen 6 verriegelt werden, braucht nicht näher eingegangen zu werden, da dies bekannter Stand der Technik ist.The two side frames 1 of a printing press are connected to one another by a hollow profile 2. The hollow profile 2 carries an upward-pointing support arm 3 at both ends, some of which are embedded in the side frames 1. In a known manner, the side frames 1 are provided with elongated holes which receive the roller journals 4, the support arms also having mouth-like receiving recesses 6. The design of the devices by means of which the bearing pins 4 are locked in the elongated holes 5 and the recesses 6 need not be discussed in more detail, since this is known prior art.

Mit dem Hohlprofil 2 sind nach unten ragende Halter 7 fest verbunden, die nach unten ragende Zapfen 8 aufweisen. Auf die beiden Zapfen der äußeren beiden Halter 7 sind Hebel 9 aufgesetzt, die an ihren den Zapfen 8 abgewandten Enden gelenkig mit Konsolen 10 verbunden sind. Die beiden Konsolen 10 sind mit einer U-Schiene 11 fest verschweißt und tragen diese. Über eine Kolben-Zylinder-Einheit 12, die einerseits am mittleren Halter 7 und andererseits an einem der beiden Nebel 9 angreift, kann die U-Schiene aus der in Figur 3 mit vollen Linien dargestellten Lage in die mit strichpunktierten Linien dargestellte Lage verschwenkt werden. Die U-Schiene 11 nimmt zwei Führungsrollen 13 auf, die über Arme 14 fest mit dem Einschubwagen 15 verbunden sind. Dies bedeutet, daß mit der Schwenkbewegung der Führungs­schiene 11 auch der Einschubwagen 15 zwischen die beiden Seiten­gestelle 1 eingefahren wird. Die Grundstellung der U-Schiene 11, aus der heraus eine neue Druckwalze eingefahren werden soll, ist in der Figur 3 mit vollen Linien dargestellt. Beim Heran­transport des Einschubwagens 15 mit aufgelegter Druckwalze muß die Bedienungsperson lediglich Sorge dafür tragen, daß die beiden Führungsrollen 13 in die U-Schiene 11 einfahren können. Danach muß die Bedienungsperson lediglich einen Druck in Pfeil­richtung A auf den Einschubwagen 15 ausüben, und zwar zumindest so lange, bis sich dieser an der Einführungsrolle 16 anlegt. Danach wird die Kolbenzylindereinheit 12 betätigt, wodurch, wie schon vorher erwähnt, die Schiene 11 aus ihrer mit vollen Linien dargestellten Lage in die mit strichpunktierten Linien darge­stellte Lage verschwenkt wird. Mit dem Einschubwagen 15 verbundene Abstandsrollen 17 sowie eine weitere mit einem Seiten­gestell 1 verbundene Einführrolle 18 tragen Sorge dafür, daß während der Einschwenkbewegung Kollisionen des Einschubwagens mit den Seitengestellen 1 vermieden werden. Während des eigentlichen Einschwenkvorgangs braucht die Bedienungsperson nur noch einen leichten Druck in Pfeilrichtung A auf den Einschub­wagen auszuüben.Downwardly projecting holders 7 are firmly connected to the hollow profile 2 and have downwardly projecting pins 8. Levers 9 are placed on the two pins of the outer two holders 7 and are connected in an articulated manner to consoles 10 at their ends facing away from the pins 8. The two brackets 10 are welded to a U-rail 11 and carry this. Via a piston-cylinder unit 12, which engages on the one hand on the middle holder 7 and on the other hand on one of the two nebulas 9, the U-rail can be shown in full lines in FIG Position can be pivoted into the position shown with dash-dotted lines. The U-rail 11 receives two guide rollers 13, which are firmly connected to the insert carriage 15 via arms 14. This means that with the pivoting movement of the guide rail 11, the slide-in carriage 15 is also inserted between the two side frames 1. The basic position of the U-rail 11, from which a new pressure roller is to be inserted, is shown in full lines in FIG. When the slide-in carriage 15 is brought up with the pressure roller placed on it, the operator only has to ensure that the two guide rollers 13 can move into the U-rail 11. Thereafter, the operator only has to exert pressure in the direction of arrow A on the slide-in carriage 15, at least until it bears against the insertion roller 16. Then the piston-cylinder unit 12 is actuated, as a result of which, as already mentioned above, the rail 11 is pivoted from its position shown in full lines into the position shown in dash-dotted lines. Spacer rollers 17 connected to the insertion carriage 15 and a further insertion roller 18 connected to a side frame 1 ensure that collisions of the insertion carriage with the side frames 1 are avoided during the pivoting-in movement. During the actual pivoting-in process, the operator only needs to exert a slight pressure in the direction of arrow A on the slide-in cart.

In den Figuren 4 und 5 ist der in den Figuren 1-3 nur ange­deutete Einschubwagen 15 deutlicher dargestellt. Aus diesen Figuren ist zu erkennen, daß der Einschubwagen 15 aus einem von Rädern 19 getragenen Grundrahmen 20 besteht, auf den nach oben weisende Seitenwände 21 fest aufgesetzt sind. Die beiden Seiten­wände 21 sind miteinander über eine obere Traverse 22 und eine untere Traverse 23 verbunden. Auf diesen Traversen sind zwei gegeneinander verstellbare Träger 24 und 25 in unterschied­ lichen Positionen zueinander feststellbar geführt, die je ein Aufnahmeprisma 26 für die Walzenzapfen 4 aufweisen. Nach dem Einführen der Walzenzapfen 4 in die Langlöcher 5 bzw. die Aufnahmeausnehmungen 6 können die Teile 27 der Prismen 25 um die Achse 28 weggeklappt werden, so daß der Einschubwagen 15 wieder herausgefahren werden kann. Dieses Heraus fahren ist nicht unbedingt erforderlich, da in bekannter Weise die Walzenzapfen nach dem Einführen in die Langlöcher 5 und die Aufnahme­ausnehmungen 6 durch Verriegelelemente um einen geringen Betrag angehoben werden und sie somit keine direkte Verbindung mehr mit den Aufnahmeprismen 26 haben.The slide-in carriage 15, which is only indicated in FIGS. 1-3, is shown more clearly in FIGS. 4 and 5. From these figures it can be seen that the slide-in carriage 15 consists of a base frame 20 carried by wheels 19, on which upwardly facing side walls 21 are firmly attached. The two side walls 21 are connected to one another via an upper cross member 22 and a lower cross member 23. On these traverses two mutually adjustable supports 24 and 25 are different Lichen positions to each other ascertainable, each having a receiving prism 26 for the roll neck 4. After inserting the roll neck 4 into the elongated holes 5 or the receiving recesses 6, the parts 27 of the prisms 25 can be folded away about the axis 28, so that the insert carriage 15 can be moved out again. This driving out is not absolutely necessary, since in a known manner the roller journals are raised by locking elements by a small amount after insertion into the elongated holes 5 and the receiving recesses 6 and thus they no longer have a direct connection to the receiving prisms 26.

In den Figuren 4 und 5 ist angedeutet, daß die Träger 24 und 25 über eine in der Traverse 23 vorgesehene Schwalbenschwanzführung 29 gehalten unhd über Schrauben 30 sowie in der Traverse 23 eingebrachte Bohrungen in unterschiedlichen Stellungen verriegelt werden können.In FIGS. 4 and 5 it is indicated that the supports 24 and 25 are held by a dovetail guide 29 provided in the cross member 23 and can be locked in different positions by means of screws 30 and bores made in the cross member 23.
