Abstract

The stubs at the ends of the printing cylinder in a rotary printing press can roll along the upper surfaces of two arms each of which carries a plate with two mutually inclined upwardly diverging grooves for a pair of reciprocable stops. The stops can be shifted by cams to assume operative positions in which they flank the respective stubs and maintain them in predetermined positions for attachment of bearings to or for removal of bearings from the stubs. The stops are retractible to levels below the upper surfaces of the respective arms so as to allow for rolling of the stubs along the arms, either to advance the cylinder to its operative position or to roll the cylinder to a position in which it can be lifted off the arms. Detents are provided to yieldably hold the stops in selected positions.

Description

Die vorstehende Erfindung betrifft eine Vorrichtung zum Auswechseln des Druckzylinders für eine Rotationsdruckmaschine.The above invention relates to a device for changing the printing cylinder for a rotary printing press.

Um in Rotationsdruckmaschinen z.B. die Druckzylinder auszuwechseln, sind an den beiden seitlichen Maschinenständern üblicherweise schwenkbar gelagerte Arme und/oder in horizontaler Lage festlegbar Arme vorgesehen, die als Aufnahmevorrichtung für die Enden des entsprechenden Druckzylinders dienen, der aus der Druckeinheit entnommen, oder in diese eingesetzt werden soll (Siehe z.B. FR-A-1269425). Während des Entladens eines Druckzylinders wird dieser demontiert und mit rollender Bewegung auf den horizontal angeordneten Armen bewegt. Es ist bekannt, dass in einer genau festgelegten Stellung anschliessend die Kugellager von den Naben des Druckzylinders abgezogen werden, wobei die Lager auf geeigneten, seitlich angeordneter Halterungen abgelegt werden. Anschliessend muss es möglich sein, den Druckzylinder zu den freien Enden der horizontal angeordneter Haltearme zu bewegen, wobei der Druckzylinder an den Enden der Haltearme, z.B. unter Verwendung eines Hubwagens, aus der Maschine entnommen wird.In order to use e.g. to replace the printing cylinders, arms are usually provided on the two side machine stands and / or arms can be fixed in a horizontal position, which serve as a receiving device for the ends of the corresponding printing cylinder, which is to be removed from the printing unit or inserted into it (see e.g. FR-A-1269425). While unloading a printing cylinder, it is dismantled and moved with a rolling movement on the horizontally arranged arms. It is known that the ball bearings are then pulled off the hubs of the printing cylinder in a precisely defined position, the bearings being placed on suitable, laterally arranged brackets. It must then be possible to move the pressure cylinder to the free ends of the horizontally arranged holding arms, the pressure cylinder at the ends of the holding arms, e.g. using a pallet truck that is removed from the machine.

Soll hingegen ein neuer Druckzylinder in der Maschinen montiert werden, so wird dieser mit den Naben und ohne die genannten Kugellager auf den horizontal angeordneten Haltearmen abgelegt. Anschliessend, nach Verschieben in eine genau definierte Lage, die der Anordnung der Haltevorrichtung für die Lager entspricht, werden die Lager auf den Naben des Druckzylinders aufmontiert und im Anschluss erfolgt die Montage des Druckzylinders in seiner Arbeitsstellung.If, on the other hand, a new pressure cylinder is to be installed in the machine, it is placed on the horizontally arranged holding arms with the hubs and without the ball bearings mentioned. Then, after moving it to a precisely defined position, which corresponds to the arrangement of the holding device for the bearings, the bearings are mounted on the hubs of the printing cylinder and then the printing cylinder is mounted in its working position.

Es ist leicht verständlich, dass sowohl für die Demontage der Kugellager des Druckzylinders als auch für die Montage dieser Lager, der Druckzylinder fest und genau in der dafür vorgeschriebenen Lage gehalten werden muss und nach ausgeführter Montage bzw. Demontage der Lager muss gewährleistet sein, dass der Druckzylinder frei beweglich auf den horizontal angeordneten Armem abgerollt werden kann.It is easy to understand that both for the disassembly of the ball bearings of the pressure cylinder and for the assembly of these bearings, the pressure cylinder must be held firmly and exactly in the position prescribed for it and after the assembly or disassembly of the bearings must be ensured that the Printing cylinder can be rolled freely on the horizontally arranged arms.

Es ist verständlich, dass die Positionierung des Druckzylinders zur Durchführung der beschriebenen Arbeiten genau und vor allem ohne Zeitverlust durchführbar sein muss.It is understandable that the positioning of the printing cylinder for performing the work described must be carried out precisely and above all without wasting time.

Es ist aus dem Stand der Technik (z.B. DE-A-2314523) eine Vorrichtung zum Festlegen der genauen Lage eines Druckzylinders bekannt, die im wesentlichen aus einem Hebelarm besteht, der um einen horizontal angeordneten Stift verschwenkbar ist und an seiner Oberseite eine Halterung aufweist, die geeignet ist, die entsprechende Nabe des Druckzylinders aufzunehmen. Der Schwenkhebel arbeitet mit einer Blockiervorrichtung zur Festlegung seiner genauen Lage zusammen und die Vorrichtung ist entlang einer Führungsschiene bewegbar, um somit verschiedene Lagen des Schwenkhebels festlegen zu können. Diese bekannte Ausführungsform hat den Nachteil, dass stets ein Betätigen der Positioniervorrichtung von Hand notwendig ist, um somit durch Verschieben der genannten Vorrichtung die geeignete Lage zum Beschicken bzw. zum Entnehmen festzulegen oder ein Blockieren des Schwenkhebels vorzunehmen.A device for determining the exact position of a printing cylinder is known from the prior art (for example DE-A-2314523), which essentially consists of a lever arm which can be pivoted about a horizontally arranged pin and has a holder on its top, which is suitable for receiving the corresponding hub of the printing cylinder. The swivel lever works with a blocking device to determine its exact position and the device can be moved along a guide rail so that different positions of the swivel lever can be fixed. This known embodiment has the disadvantage that manual actuation of the positioning device is always necessary in order to thus determine the suitable position for loading or unloading or to block the pivoting lever by moving said device.

Da die genannte Vorrichtung zwischen dem Kopfende des Druckzylinders und der Innenwand des seitlichen Maschinenständers vorgesehen ist, besteht die Gefahr, dass jede Einwirken von Hand auf die genannte Vorrichtung Grund zu Verletzungen an den Händen der Bedienungsperson sein kann. Ferner tritt bei der bekannten Vorrichtung auch der Nachteil auf, dass bei versehentlichem Anordnen der Blockiervorrichtung in einer Stellung, die für den durchzuführenden Arbeitsvorgang ungeeignet ist, die Durchführung des gewünschten Arbeitsvorganges nicht möglich ist, wodurch ein erheblicher Zeitverlust beim Einbau oder Ausbau des Druckzylinders auftreten kann.Since the device mentioned is provided between the head end of the pressure cylinder and the inner wall of the side machine stand, there is a risk that any action by hand on the device mentioned can cause injuries to the hands of the operator. Furthermore, the known device also has the disadvantage that if the blocking device is inadvertently arranged in a position which is unsuitable for the work to be carried out, it is not possible to carry out the desired work, which can result in a considerable loss of time when installing or removing the pressure cylinder .

Es ist Aufgabe der vorstehenden Erfindung, die Nachteile des Standes der Technik zu vermeiden und eine neue Vorrichtung zum Positionieren eines Druckzylinders auf den horizontal angeordneten Haltearmen zum Beschicken bzw. zum Entladen des Zylinders vorzuschlagen, die einfache und kostengünstige Bauweise aufweist, die ein automatisches Beschicken oder Festlegen in einer bestimmten Lage ermöglicht, und die lediglich für das Festlegen in einer bestimmten Arbeitslage bzw. für das Entladen des Druckzylinders einen Eiongriff von Hand erfordert, der schnell und ohne jegliche Unfallgefahr durchführbar ist.It is an object of the above invention to avoid the disadvantages of the prior art and to propose a new device for positioning a printing cylinder on the horizontally arranged holding arms for loading or unloading the cylinder, which has a simple and inexpensive design which is automatic loading or Setting in a certain position enables, and which only requires a manual eion grip for fixing in a certain working position or for unloading the pressure cylinder, which can be carried out quickly and without any risk of accident.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass jeder Haltearm zum Beladen bzw. zum Entladen eines Druckzylinders an der Aussenseite der Maschinenständer jeweils zwei Leisten aufweist, die beweglich in entsprechenden Führungen gelagert sind, dass diese Leisten nach oben hin auseinanderlaufend angeordnet sind und einen V-förmigen Sitz festlegen, der geeignet ist, die entsprechende Nabe des Druckzylinders aufzunehmen, dass die unteren Enden der Leisten mit einer Positioniervorrichtung und einer schwenkbaren Antriebseinrichtung zusammenarbeiten, von der ein Ende dem unteren Endstück der ersten Leiste und das andere Ende dem unteren Enstück der zweiten Leiste zugeordnet ist.According to the invention, this object is achieved in that each holding arm for loading or unloading a printing cylinder has two strips on the outside of the machine frame, which are movably mounted in corresponding guides, that these strips are arranged diverging upwards and have a V-shape Determine the seat, which is suitable for receiving the corresponding hub of the pressure cylinder, that the lower ends of the strips cooperate with a positioning device and a pivotable drive device, one end of which is assigned to the lower end piece of the first strip and the other end to the lower end piece of the second strip is.

Mit besonderem Vorteil sind die Leisten mit Spiel in einer Platte gelagert, die zwei Einfräsungen aufweist, die V-förmig zueinander angeordnet sind. Ferner weisen die verschiebbar gelagerten, Leisten eine fensterartige laengliche Öffnung auf, die von einem Führungsstift durchdrungen wird, der fest mit dem Auflagearm zum Beschicken und Entnehmen des Druckzylinders oder mit dem plattenförmigen Körper, der die V-förmig angeordneten Führungen aufweist, verbunden ist.The strips are particularly advantageously mounted with play in a plate which has two millings which are arranged in a V-shape with respect to one another. Furthermore, the slidably mounted, strips have a window-like elongated opening, which is penetrated by a guide pin which is fixedly connected to the support arm for loading and removing the printing cylinder or to the plate-shaped body which has the V-shaped guides.

In vorteilhafter Weise, ist die Positionier- und Antriebsvorrichtung, die den verschiebbaren Leisten zugeordnet ist, aus einem Schwenkbolzen gebildet, der beweglich in den Haltearmen für das Beschicken und Entladen des Zylinders angeordnet ist und, exzentrisch mit diesem Schwenkarm ist eine halbkreisförmige Platte verbunden, deren diametral gegenüberliegende Enden an den unteren Endseiten der verschiebbaren Leisten anliegen. An der Unterseite dieser scheibenförmigen Platte ist ein Betätigungsgriff vorgesehen.Advantageously, the positioning and drive device, which is assigned to the displaceable strips, is formed from a pivot pin which is movable in the holding arms for loading and unloading the cylinder is arranged and, eccentrically with this swivel arm, a semicircular plate is connected, the diametrically opposite ends of which rest on the lower end sides of the displaceable strips. An operating handle is provided on the underside of this disc-shaped plate.

Es ist ferner vorteilhaft, dass im Inneren des Betätigungsgriffes ein Sackloch angeordnet ist, dass eine Feder aufnimmt, die auf eine Kugel einwirkt, die mit Bezugsbohrungen und Positinierbohrungen, die in Haltearmen zum Beschikken und Entladen des Druckzylinders vorgesehen sind, zusammenwirkt.It is also advantageous that a blind hole is arranged in the interior of the actuating handle, which receives a spring which acts on a ball which interacts with reference bores and positioning bores which are provided in holding arms for loading and unloading the pressure cylinder.

In der horizonhtalen Lage der Haltearme ist das Entladen bzw. das Beladen eines Druckzylinders möglich, wobei die beiden Naben 2 in beiden Richtungen des Pfeiles (f) auf den horizontalen Armen 1 abrollbar sind.As can be seen in FIG. 1, a holding arm 1 is provided on the outside of the side machine stand of the rotary printing press, which can be pivoted from a vertical rest position into a horizontal working position. In the horizontal position of the holding arms, unloading or loading of a pressure cylinder is possible, the two hubs 2 being able to be rolled on the horizontal arms 1 in both directions of the arrow (f).

Um zu ermöglichen, dass von den Naben 2 nicht dargestellte Kugellager abgezogen bzw. aufmontiert werden, ist es unumgänglich, dass die beiden Naben 2 des Druckzylinders in einer genau festgelegten Lage der Arme 1 positionierbar sind und in diese Lage genau festlegbar ist. Um diesen Positioniervorgang durchführen zu können, ist jeder Arm 1 auf seiner Aussenseite mit einer gesamthaft mit 3 bezeichneten Vorrichtung versehen.In order to enable ball bearings (not shown) to be pulled off or mounted, it is essential that the two hubs 2 of the pressure cylinder can be positioned in a precisely defined position of the arms 1 and can be precisely fixed in this position. In order to be able to carry out this positioning process, each arm 1 is provided on the outside with a device which is denoted overall by 3.

Die Vorrichtung 3 besteht im wesentlichen aus einer Platte 4, die unter Zuhilfenahme von Schrauben 5 am entsprechenden Haltearm 1 befestigt ist. Auf der zum Arm 1 gerichteten Seite weist die Platte innere Einfräsungen 6 und 7 auf, die V-förmige angeordnet sind. Die Führungen 6 und 7 nehmen frei verschiebbar in Richtung der Pfeile (g) Leisten 8 und 9 auf, die bei ausgefahrener Stellung über die Abrollebene 10 des entsprechenden Haltearmes 1 ragen, wodurch ein V-förmiger Sitz gebildet wird, der mit 11 gekennzeichnet ist und geeignet ist, die entsprechende Nabe 2 des Druckzylinders in seiner genau festgelegten Lage festzulegen, um die Montage bzw. die Demontage des entsprechenden Kuggelagers, der der entsprechenden Nabe 2 zugeordnet ist, zu ermöglichen. Die Leisten 8 und 9 weisen in vorteilhafter Weise Langlöcher 12 und 13 auf, die in Richtung der Längsachse der Leisten 8 und 9 verlaufen. Diese Langlöcher 12 und 13 bilden Führungsschlitz, mit denen Führungsstifte 14 und 15 in Verbindung stehen. Die Führungsstifte 14 und 15 sind in vorteilhafter Weise am Grund der Ausfräsungen 6 und 7 der Platte 4 oder auf den Haltearmen direkt angeordnet. Die oberen Enden 8a und 9a der Leisten 8 und 9 sind derartig abgeschnitten, dass sie parallel zur Abrollfläche 10 des entsprechenden Haltearmes 1 ausgerichtet sind, wogegen die unteren Enden 8b und 9b der Leisten 8 und 9 derartig abgetrennt sind, dass sie an der Unterseite der Platte 4 einen Raum 16 begrenzen.

Die Arbeitsweise der erfindungsgemässen Vorrichtung wird nun genauer anhand der Fig. 2 beschrieben.The operation of the device according to the invention will now be described in more detail with reference to FIG. 2.

Wenn der Druckzylinder z.B. entladen werden soll, rollen seine Naben 2 auf der Oberfläche 10 des linken und rechten Haltearmes 1 ab und laufen im beschriebenen Beispiel auf den abgrundeten Enden der Leiste auf, die sich z.B. in ausgefahrener Stellung befindet, wie dies durch Strichpunktlinien dargestellt ist. Die durch die Nabe auf das Leistenende ausgeübte Kraft bewirkt, dass die Leiste nach unten in die mit vollen Linien dargestellte Stellung verschoben wird und sich somit mit dem Ende 8a unter der Abrollebene 10 befindet. Dadurch kann die Nabe 2 eine unbehinderte Abrollbewegung in Richtung des Pfeiles (F) durchführen. Bei Verschieben der Leiste 8 nach unten, wirkt diese mit ihrem Ende 8b auf das Endstück 19a des halbkreisförmigen Betätigungsteiles 19 ein, wodurch dieses aus seiner mit Strichpunktlinien dargestellten Stellung in die mit vollen Linien dargestellte Lage verdreht wird. Dadurch wird über das Endstück 19b die Leiste 9 in die maximal ausgefahrene Stellung verschoben und somit wird jegliche weitere Abrollbewegung der Nabe 2 in Richtung der Pfeiles (f) verhindert.If the pressure cylinder is to be unloaded, for example, its hubs 2 roll off on the surface 10 of the left and right holding arms 1 and run in the example described on the abraded ends of the bar, which is, for example, in the extended position, as shown by chain lines . The force exerted on the end of the strip by the hub causes the strip to be shifted downwards into the position shown in full lines and is thus located with the end 8a below the rolling plane 10. This allows the hub 2 to move freely in the direction the arrow (F). When the bar 8 is moved downwards, it acts with its end 8b on the end piece 19a of the semicircular actuating part 19, as a result of which the latter is rotated from its position shown in broken lines to the position shown in solid lines. As a result, the bar 9 is displaced into the maximally extended position via the end piece 19b and any further rolling movement of the hub 2 in the direction of the arrow (f) is prevented.

Im Anschluss an eine Drehbewegung nach links des Betätigungsgriffes 20 wird die Betätigungsschiebe 9 erneut in ihre mittige Lage verdreht, wie diese durch Strichpunktlinien dargestellt ist, und es wird bewirkt, dass die Leiste 8 aus der mit Strichpunktlinien dargestellten Lage ausgefahren wird. Dadurch wird die Nabe 2 endgültig in der gewünschten Stellung blockiert. Es wird somit eine Bewegung nach links verhindert, und die eingenommene Lage ist geeignet, für die Montage bzw. die Demontage des Kuggellagers auf bzw. von der Nabe 2.Following a rotary movement to the left of the actuating handle 20, the actuating slide 9 is rotated again into its central position, as is shown by dash-and-dot lines, and it is caused that the strip 8 is moved out of the position shown with dash-and-dot lines. As a result, the hub 2 is finally blocked in the desired position. Movement to the left is thus prevented, and the position assumed is suitable for the assembly or disassembly of the ball bearing on or from the hub 2.

Soll hingegen ein neuer Druckzylinder in die Maschine eingefahren werden, so erfolgt die Abrollbewegung des Nabe 2 von rechts nach links (Fig. 2). In diesem Fall wiederholen sich die bisher beschriebenen Bewegungsvorgänge der Leisten 8 und 9, sowie der Positiniervorrichtung 19 in entgegengesetzter Richtung.If, on the other hand, a new pressure cylinder is to be inserted into the machine, the hub 2 will roll from right to left (FIG. 2). In this case, the previously described movement processes of the strips 8 and 9 and the positioning device 19 are repeated in the opposite direction.
