Description

Beschreibungdescription
Vorrichtung zur Montage, Demontage und Transport von leicht biegbaren, bogenförmigen Gegenständen mit EinhängeabkantungenDevice for assembling, disassembling and transporting easily bendable, curved objects with bent edges
Die Erfindung betrifft eine Vorrichtung zur Montage, Demontage und Transport von leicht biegbaren, bogenförmigen Gegenständen mit Einhängeabkantungen, vorzugsweise Druckplatten, auf und von einem Zylinder einer Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for assembling, disassembling and transporting easily bendable, arc-shaped objects with hooked-in bends, preferably printing plates, on and from a cylinder of a rotary printing press according to the preamble of claim 1.
Die DE 28 04 970 AI beschreibt eine Einrichtung zur Montage und -Demontage von Druckplatten in einer Rotationsdruckmaschine.DE 28 04 970 AI describes a device for assembling and disassembling printing plates in a rotary printing press.
Hierbei führt ein Saugorgan eine lineare Bewegung zwischen einer Abgabewalze und einem Plattenzylinder aus und transportiert damit die Druckplatte. Dieses Saugorgan ist mittels Zylinder an einem Schlitten befestigt, der durch eine Kette angetrieben wird. Durch diesen Zylinder kann das Saugorgan rechtwinklig zur Schlittenbewegung eine Hubbewegung zum Anheben und Absenken der Druckplatte ausführen. Zur Montage fixiert das Saugorgan ein vorderes, abgekantetes Ende der Druckplatte durch Einschalten der Saugwirkung. Mittels des Zylinders wird das Saugorgan mit der Platte angehoben und in Richtung Plattenzylinder durch den Schlitten mit Kettenantrieb befördert. Zwischen Abgabewalze und Plattenzylinder befindet sich ein Positioniertisch auf dem die Druckplatte aufgelegt und positioniert wird. Danach übernimmt das Saugorgan wieder die Druckplatte und transportiert diese zu einer Nut des Plattenzylinders. Durch Absenken des Saugorgans wird das abgekantete Ende der Druckplatte in diese Nut des Plattenzylinders eingeführt.Here, a suction element performs a linear movement between a delivery roller and a plate cylinder and thus transports the printing plate. This suction element is attached to a slide by means of a cylinder, which is driven by a chain. Through this cylinder, the suction element can perform a lifting movement at right angles to the slide movement for raising and lowering the pressure plate. For assembly, the suction element fixes a front, bent end of the pressure plate by switching on the suction effect. The suction element with the plate is lifted by means of the cylinder and conveyed in the direction of the plate cylinder through the carriage with chain drive. Between Dispensing roller and plate cylinder is a positioning table on which the printing plate is placed and positioned. The suction element then takes over the pressure plate again and transports it to a groove in the plate cylinder. The folded end of the pressure plate is inserted into this groove of the plate cylinder by lowering the suction element.
Nach Abstellen der Saugwirkung dreht sich der Plattenzylinder mit der Druckplatte, die sich gleichzeitig von der Abgabewalze abwickelt. Ist die Druckplatte fast vollständig von der Abgabewalze abgerollt, erfaßt das Saugorgan ein hinteres Ende der Druckplatte und führt dieses in eine weitere Nut des Plattenzylinders.After the suction is switched off, the plate cylinder rotates with the pressure plate, which simultaneously unwinds from the delivery roller. When the printing plate is almost completely unrolled from the delivery roller, the suction element grasps a rear end of the printing plate and guides it into another groove in the plate cylinder.
Nachteilig an dieser Einrichtung ist, daß die Druckplatte auf einem Positioniertisch, der sich zwischen Abgabewalze und Plattenzylinder befindet, abgelegt und positioniert werden muß. Während des Transportes der Druckplatte vom Positioniertisch zum Zylinder und während des Einhängevorganges der Druckplatte im Zylinder können Toleranzen aufgrund beispielsweise Spiel in der Schlittenführung auftreten, die eine fehlerhafte axiale Position der Druckplatte auf dem Zylinder hervorrufen.A disadvantage of this device is that the printing plate has to be placed and positioned on a positioning table which is located between the delivery roller and the plate cylinder. During the transport of the printing plate from the positioning table to the cylinder and during the mounting process of the printing plate in the cylinder, tolerances can occur due to, for example, play in the slide guide, which cause an incorrect axial position of the printing plate on the cylinder.
Die US 47 27 807 A beschreibt eine Vorrichtung zur Montage und Demontage von Druckplatten in einer Rotationsdruckmaschine. Hierbei wird eine Handhabungsvorrichtung, die die Druckplatte aufnimmt, von einem Roboter zwischen einer Bereitstellungseinrichtung und einem Plattenzylinder bewegt. An der Handhabungseinrichtung sind vier Sauggreifer, mit denen die Druckplatte gehalten wird, starr angebracht.The US 47 27 807 A describes a device for assembling and disassembling printing plates in a rotary printing press. Here, a handling device that receives the printing plate is moved by a robot between a supply device and a plate cylinder. Four suction pads with which the pressure plate is held are rigidly attached to the handling device.
Zur Montage wird die Druckplatte von der Bereitstellungseinrichtung zum Plattenzylinder durch mehrachsige Bewegungen des Roboters befördert und mit einer Abkantung in einen Spannkanal des Zylinders eingehangen.For assembly, the pressure plate is conveyed from the supply device to the plate cylinder by multi-axis movements of the robot and hooked into a clamping channel of the cylinder with a bend.
Die axiale Positionierung der Druckplatte erfolgt über einen Antrieb, der über Kraftsensoren geregelt wird. Anschließend werden vier Andrückrollen durch Schwenken der Handhabungseinrichtung angestellt. Durch Drehen des Plattenzylinders wird die Druckplatte auf den Plattenzylinder aufgebracht und ein weiteres Ende in den Kanal eingeführt.The pressure plate is positioned axially via a drive that is controlled by force sensors. Four pressure rollers are then turned on by swiveling the handling device. By rotating the plate cylinder, the pressure plate is applied to the plate cylinder and another end is inserted into the channel.
Nachteilig an dieser Vorrichtung ist, daß die Handhabungseinheit in radialer Ebene des Plattenzylinders in mehreren Richtungen bewegbar und schwenkbar sein muß und hierzu komplizierte Antriebe und Steuerungen nötig sind. Außerdem können pro Zylinder nicht mehrere Druckplatten gleichzeitig transportiert und montiert bzw. demontiert werden.A disadvantage of this device is that the handling unit must be movable and pivotable in several directions in the radial plane of the plate cylinder, and complicated drives and controls are necessary for this. In addition, several printing plates per cylinder cannot be transported, assembled or disassembled at the same time.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Montage, Demontage und Transport von leicht biegbaren, bogenförmigen Gegenständen mit Einhängeabkantungen, vorzugsweise Druckplatten, deren jeweilige Schenkel einen Öffnungswinkel kleiner 90° einschließen und die keine Aussparungen für Registerstifte aufweisen, auf und von einem Zylinder zu schaffen, die in einer Parkposition eine hindernisfreie Bedienung und Wartung sowie eine freie Zugänglichkeit der Druckwerke ermöglicht.The invention has for its object a Device for assembling, disassembling and transporting easily bendable, arch-shaped objects with hooked edges, preferably pressure plates, the respective legs of which include an opening angle of less than 90 ° and which have no recesses for register pins, on and from a cylinder, which in an unobstructed parking position Operation and maintenance as well as free access to the printing units.

In besonders vorteilhafter Weise muß eine Greif- und Andrückeinrichtung nur einen sehr kleinen Weg zurücklegen, um in eine Parkposition bzw. in Arbeitsstellung zu gelangen, was für kurze Plattenwechselzeiten sehr wichtig ist. Befindet sich die Greif- und Andrückeinrichtung in Parkposition ist eine gute Zugänglichkeit zum Zylinder und zu einem dazugehörigen Farbwerk gewährleistet. Somit ist jederzeit auch ein manueller Plattenwechsel möglich, ohne daß die erfindungsgemäße Vorrichtung dabei behindert.In a particularly advantageous manner, a gripping and pressing device only has to travel a very small distance in order to get into a parking position or into a working position, which is very important for short plate changing times. If the gripping and pressing device is in the park position, good accessibility to the cylinder and to an associated inking unit is guaranteed. A manual plate change is thus possible at any time without the device according to the invention being impeded.
In der Parkposition ist die Greif- und Andrückeinrichtung von einem Schutz umschlossen und so vor Schmutz und Farbnebel geschützt, was die Funktionεsicherheit erhöht und den Wartungsaufwand minimiert.In the park position, the gripping and pressing device is enclosed by a protection and thus protected from dirt and paint mist, which increases the functional reliability and the maintenance effort minimized.

An jedem leicht biegbaren, bogenförmigen Gegenstand 2 sind an dessen gegenüberliegenden Enden jeweils vordere und hintere Einhängeabkantungen 3, 4 angeordnet, deren jeweilige Schenkel 6, 7 einen Öffnungswinkel Alpha kleiner als 90° einschließen. Diese Einhängeabkantungen 3, 4 sind formstabil ausgebildet, d. h. beim Spannen der Gegenstände 2 auf dem Zylinder 1 werden diese Einhängabkantungen 3, 4 nicht aufgebogen. Dieser derart gestaltete Gegenstand 2 kann auch aus Druckgummitüchern, die mit Einhängeabkantungen 3, 4 versehen sind, bestehen.On each easily bendable, arc-shaped object 2, front and rear hook-in edges 3, 4 are arranged at the opposite ends thereof, the each leg 6, 7 include an opening angle alpha less than 90 °. These hook-in folds 3, 4 are designed to be dimensionally stable, ie, when the objects 2 are clamped on the cylinder 1, these hook-in folds 3, 4 are not bent open. This object 2 designed in this way can also consist of printing rubber blankets which are provided with hooked-in folds 3, 4.
Diese formstabilen Einhängeabkantungen 3, 4 der Druckgummitücher können abgekanteten Enden einer Metallplatte sein, auf der das Druckgummituch stoffschlüssig befestigt, beispielsweise geklebt oder vulkanisiert wurde. Auch können insbesondere die Gewebeeinlagen des Druckgummituches aus CFK (Kohlefaser verstärkter Kunststoff) oder GFK (Glasfaser verstärkter Kunststoff) gefertigt und daraus die Einhängeabkantungen 3, 4 geformt sein. Vereinfachend wird im folgenden dieser beschriebene Gegenstand Druckplatte 2 genannt.These dimensionally stable hook-in folds 3, 4 of the printing rubber blankets can be folded ends of a metal plate on which the printing rubber blanket has been firmly bonded, for example glued or vulcanized. In particular, the fabric inserts of the printing rubber blanket can be made of CFRP (carbon fiber reinforced plastic) or GRP (glass fiber reinforced plastic) and the hooked-in folds 3, 4 can be formed therefrom. To simplify matters, this described object is called pressure plate 2 in the following.
Dem Zylinder 1 der Rotationsdruckmaschine, der in zwei Seitengestellen 8, 9 gelagert ist, ist ein zylindernaher, gestellfester Farbwerkschutz 11 zugeordnet, der als eine erste Druckplatten-Bereitstellungseinrichtung 12 ausgebildet ist.The cylinder 1 of the rotary printing press, which is mounted in two side frames 8, 9, is associated with an inking unit protection 11 which is close to the cylinder and is designed as a first printing plate preparation device 12.
Diese Druckplatten-Bereitstellungseinrichtung 12 weist eine obere und eine untere, der oberen gegenüberliegenden Wand 13, 14 auf, die zusammen einen Schacht 16 bilden. An einem plattenzylindernahen Ende 17 der oberen Wand 13 ist eine sich über die Breite des Zylinders 1 erstreckende, parallel zu einer Drehachse 18 des Zylinders 1 verlaufende Einhängeleiste 19 mit nasenförmigen Querschnitt angebracht. Das plattenzylindernahe' Ende 17 der oberen Wand 13 ist annähernd parallel zu einer Tangente 21, die von einer Zylindermantelfläche 22 des Zylinders 1 und der Einhängeleiste 19 der Druckplatten-Bereitstellungseinrichtung 12 bestimmt wir , ausgebildet.This pressure plate supply device 12 has an upper and a lower, the upper opposite wall 13, 14, which together form a shaft 16. On a plate cylinder near Attached to the end 17 of the upper wall 13 is a hanging strip 19 with a nose-shaped cross section, which extends across the width of the cylinder 1 and runs parallel to an axis of rotation 18 of the cylinder 1. The plate cylinder close 'end 17 of the upper wall 13 is approximately parallel to a tangent 21 of a cylinder mantle surface 22 of the cylinder 1 and the suspension strip 19 of the printing plate-providing device 12, we determined is formed.
Neben der ersten Druckplatten-Bereitstellungseinrichtung 12 kann wie im vorliegenden Beispiel eine zweite Druckplatten-Bereitstellungseinrichtung 23 angeordnet sein, deren plattenzylindernahes Ende 24 ebenfalls mit einer Einhängeleiste 26 mit nasenförmigen Querschnitt versehen ist und annähernd parallel zu der von Zylindermantelfläche 22 des Zylinders 1 und der Einhängeleiste 19 der ersten Druckplatten-Bereitstellungseinrichtung 12 festgelegten Tangente 21 ausgebildet ist.In addition to the first printing plate preparation device 12, a second printing plate preparation device 23 can be arranged, as in the present example, whose plate cylinder-near end 24 is also provided with a hanging bar 26 with a nose-shaped cross section and approximately parallel to that of the cylinder jacket surface 22 of the cylinder 1 and the hanging bar 19 of the first printing plate supply device 12 is defined tangent 21.
Oberhalb und parallel zu dieser Tangente 21 ist in den Seitengestellen 8, 9 jeweils eine rechter und linker Linearantrieb 27, 28 befestigt, der beispielsweise jeweils aus Gewindespindeln 29, 31 die drehbar in gestellfesten Böcken 32, 33, 34, 36 gelagert sind, besteht. Ebenso können andere bekannte Linearantriebe 27, 28, wie z. B. Riemen- bzw. Kettenantriebe, Zahnstangenantriebe, hydraulische bzw. pneumatische Servozylinder oder Linearmotoren eingesetzt werden. Über einen Riemen 37, z. B. Zahnriemen, der die rechte und linke Gewindespindel 29, 31 mechanisch synchronisiert, wird durch einen Antrieb 38 eine synchrone Drehbewegung der Gewindespindeln 29, 31 erzeugt. Diese Synchronisation kann beispielsweise mechanisch auch über Ketten- oder Gelenkwellen oder elektronisch über zwei getrennte Antriebe 38 der Linearantriebe 27, 28 erfolgen. Die beiden Gewindespindein 29, 31 bewegen eine zur Drehachse 18 des Zylinders 1 parallele Traverse 39 in einer Transportebene 41, die oberhalb und annähernd parallel zur von Zylindermantelfläche 22 des Zylinders 1 und Einhängeleiste 19 der Druckplatten-Bereitstellungseinrichtung 12 bestimmten Tangente 21 liegt. An den beiden Enden dieser Traverse 39 sind jeweils Gewindemuttern 42 angeordnet, so daß die Traverse 39 rechtwinklig mit den Gewindespindein 29, 31 in Wirkverbindung steht. Entlang dieser Traverse 39 ist mindestens eine Greif- und Andrückeinrichtung 43, im dargestellten Beispiel sind vier Greif- und Andrückeinrichtungen 43 befestigt.Above and parallel to this tangent 21, a right and left linear drive 27, 28 is fastened in the side frames 8, 9, which consists, for example, of threaded spindles 29, 31 which are rotatably mounted in frames 32, 33, 34, 36 fixed to the frame. Likewise, other known linear drives 27, 28, such as. B. belt or chain drives, Rack and pinion drives, hydraulic or pneumatic servo cylinders or linear motors can be used. Via a belt 37, e.g. B. timing belt, which mechanically synchronizes the right and left threaded spindles 29, 31, a synchronous rotary movement of the threaded spindles 29, 31 is generated by a drive 38. This synchronization can take place mechanically, for example, via chain or cardan shafts or electronically via two separate drives 38 of the linear drives 27, 28. The two threaded spindles 29, 31 move a traverse 39 parallel to the axis of rotation 18 of the cylinder 1 in a transport plane 41 which lies above and approximately parallel to the tangent 21 determined by the cylinder surface 22 of the cylinder 1 and the hooking bar 19 of the printing plate preparation device 12. At the two ends of this cross member 39 there are threaded nuts 42 so that the cross member 39 is at right angles to the threaded spindles 29, 31 in operative connection. At least one gripping and pressing device 43 is attached along this traverse 39; in the example shown, four gripping and pressing devices 43 are fastened.
Jeder einzelnen, einem axialen Zylinderabschnitt zugehörigen Druckplatte 2 ist eine unabhängig betätigbare Greif- und Andrückeinrichtung 43 zugeordnet. Ebenso ist es aber auch möglich mit einem zusätzlichen Linearantrieb, durch den eine einzige Greif- und Andrückeinrichtung 43 eine axiale Bewegung entlang der Traverse 39 ausführt, mehrere entlang des Zylinders 1 angeordnete Druckplatten 2 mit nur einer einzigen Greif- und Andrückeinrichtung 43 zu wechseln.Each individual pressure plate 2 belonging to an axial cylinder section is assigned an independently actuable gripping and pressing device 43. However, it is also possible with an additional linear drive, through which a single gripping and pressing device 43 an axial movement along the Traverse 39 executes to change several pressure plates 2 arranged along the cylinder 1 with only a single gripping and pressing device 43.
In Fig. 2 sind die Elemente einer Greif- und Andrückeinrichtung 43 dargestellt:The elements of a gripping and pressing device 43 are shown in FIG. 2:
Eine Greif- und Andrückeinrichtung 43 besteht aus mindestens einer Greifereinheit 44 und mindestens einer Andrückrolle 46. Diese Greifereinheit 44 und die Andrückrollen 46 sind bezüglich des Zylinders 1 in radialer Richtung "D", die Greifereinheit 44 zusätzlich noch in axialer Richtung "C", unabhängig voneinander durch Positioniereinrichtungen verschiebbar.A gripping and pressing device 43 consists of at least one gripper unit 44 and at least one pressure roller 46. This gripper unit 44 and the pressure rollers 46 are independent of the cylinder 1 in the radial direction "D", the gripper unit 44 also in the axial direction "C" displaceable from one another by positioning devices.
Im vorliegenden Beispiel ist die Greif- und Andrückeinrichtung 43 annähernd symmetrisch zur in Zylinderumfangsrichtung verlaufenden Mittellinie der Druckplatte 2 aufgebaut:In the present example, the gripping and pressing device 43 is constructed approximately symmetrically to the center line of the pressure plate 2 running in the cylinder circumferential direction:
Je Greif- und Andrückeinrichtung 43 ist eine Greifereinheit 44 in Form von z. B. zwei Saugleisten 47 ausgebildet, die senkrecht zu einer Führungsleiste 48 verdrehgesichert entgegen tangentialer Richtung "B" des Zylinders 1 verschiebbar sind und durch Druckfedern 49 in Richtung "B" gegen einen Anschlag 51 gedrückt werden.Each gripping and pressing device 43 is a gripper unit 44 in the form of z. B. two suction strips 47 are formed which are perpendicular to a guide bar 48 against rotation tangential direction "B" of the cylinder 1 and are pressed by compression springs 49 in the direction "B" against a stop 51.
Diese Führungsleisten 48 sind an einer weiteren Führungsleiste 52 befestigt und durch einen Pneumatikzylinder 53 entgegen Richtung "C" verschiebbar. Ein Pneumatikzylinder 54 bewirkt eine Positionsveränderung der Führungsleiste 52 mit den Saugleisten 47 entlang der Richtung "D". Neben den Saugleisten 47 befindet sich jeweils eine Andrückrolle 46, die über einen Pneumatikzylinder 56 entgegen Richtung "D" auf die Druckplatte 2 angestellt werden kann.These guide strips 48 are fastened to a further guide strip 52 and can be displaced in the opposite direction "C" by a pneumatic cylinder 53. A pneumatic cylinder 54 causes one Change in position of the guide bar 52 with the suction bars 47 along the direction "D". In addition to the suction strips 47 there is a pressure roller 46 which can be placed against the pressure plate 2 against the direction "D" by means of a pneumatic cylinder 56.
Im vorliegenden Beispiel sind in dem Zylinder 1 in axialer Richtung, parallel zur Drehachse 18 des Zylinders 1 verlaufend, vier Verschlüsse 57, 58, 59, 61 angeordnet. Die Länge der Verschlüsse 57,In the present example, four closures 57, 58, 59, 61 are arranged in the cylinder 1 in the axial direction, parallel to the axis of rotation 18 of the cylinder 1. The length of the closures 57,
58, 59, 61 beträgt jeweils ca. halbe Zylinderlänge. Diese Verschlüsse 57, 58, 59, 61 sind nochmals auf Plattenbreite unterteilt (d. h. pro Verschluß 57, 58,58, 59, 61 is approximately half the cylinder length. These closures 57, 58, 59, 61 are again subdivided to plate width (i.e. per closure 57, 58,
59, 61 sind jeweils zwei Druckplatten 2 vorgesehen) und sind sowohl innerhalb dieser Unterteilung als auch untereinander unabhängig betätigbar. Die Verschlüsse 57, 58 sind in Umfangsrichtung des Zylinders 1 um ca. 90° zueinander versetzt. Jedem Verschluß 57, 58 ist jeweils ein Verschluß 59, 61 gegenüberliegend zugeordnet.59, 61 two pressure plates 2 are provided in each case) and can be actuated independently both within this subdivision and among one another. The closures 57, 58 are offset from one another by approximately 90 ° in the circumferential direction of the cylinder 1. Each closure 57, 58 is assigned a closure 59, 61 opposite each other.
Die Funktionsweise der Verschlüsse 57, 58, 59, 61 wird nachfolgend an dem Verschluß 57 (Fig. 12) näher erläutert:The operation of the closures 57, 58, 59, 61 is explained in more detail below on the closure 57 (FIG. 12):
Der Verschluß 57 ist in einer parallel zur Drehachse 18 verlaufenden Zylindergrube 62 angeordnet. Die Zylindergrube 62 begrenzend ist unterhalb der Zylindermantelfläche 22 jeweils eine vordere und hintere Einhängeleiste 63, 64 mit nasenförmigen Querschnitt am Zylinder 1 angeordnet. Der Verschluß 57 weist eine rechte und linke Spannklappe 66, 67 auf. Jede dieser Spannklappen 66, 67 erstreckt sich in axialer Richtung entlang der Drehachse 18 des Zylinders 1 über annähernd Plattenbreite. Der Querschnitt beider Spannklappen 66, 67 ist an einem unteren Ende 68 kreisbogenförmig als Lagerstelle ausgebildet, woran sich ein Hebel 69 fortsetzt, der in einer hakenförmigen Nase 71 endet. Im geöffneten Zustand der Spannklappen 66, 67 befinden sich deren Nasen 71 unterhalb der Zylindermantelfläche 22 und deren den Einhängeleisten 63, 64 des Zylinders 1 zugewandte Seiten 72 sind den Einhängeleisten 63, 64 des Zylinders 1 entsprechend abgeschrägt, so daß die Spannklappen 66, 67 im geöffneten Zustand im wesentlichen von den Einhängeleisten 63, 64 überdeckt werden.The closure 57 is arranged in a cylinder groove 62 running parallel to the axis of rotation 18. The cylinder pit 62 is delimiting below the cylinder jacket surface 22 in each case by a front and rear suspension strip 63, 64 with a nose-shaped cross section Cylinder 1 arranged. The closure 57 has a right and left clamping flap 66, 67. Each of these clamping flaps 66, 67 extends in the axial direction along the axis of rotation 18 of the cylinder 1 over approximately the width of the plate. The cross section of the two flaps 66, 67 is formed at a lower end 68 in the form of a circular arc as a bearing point, whereupon a lever 69 continues, which ends in a hook-shaped nose 71. When the tensioning flaps 66, 67 are open, their lugs 71 are located below the cylinder jacket surface 22 and their sides 72 facing the hanging strips 63, 64 of the cylinder 1 are correspondingly chamfered to the hanging strips 63, 64 of the cylinder 1, so that the tensioning flaps 66, 67 in opened state are essentially covered by the hanging strips 63, 64.
Eine der Einhängeabkantung 4 der Druckplatte 2 zugewandte Seite 73 der Nase 71 der SpannklappeA side 73 of the nose 71 of the tensioning flap facing the hooked-in bend 4 of the pressure plate 2
66 verläuft im gespannten Zustand der Spannklappe66 runs in the tensioned state of the tension flap
67 annähernd parallel zur Einhängeabkantung 3 der Druckplatte 2. Das kreisbogenförmige Ende 68 ist jeweils in einer kreisbogenförmigen Aussparung 74 der parallel zur Drehachse 18 verlaufenden Zylindergrube 62 schwenkbar gelagert. Durch Einwirkung von Federn 76 führt die Spannklappe 67 eine Schwenkbewegung in Richtung zu spannender, hinterer Einhängeabkantung 4 der Druckplatte 2 aus. Im vorliegenden Beispiel ist das kreisbogenförmige Ende 68 der Spannklappe 67 mit einer Bohrung 77 versehen, in der eine stabförmige Torsionsfeder (Drehstabfeder) 76 verläuft. Diese Drehstabfeder 76 ist an ihrem einen Ende starr und vorgespannt mit dem Zylinder 1 verbunden, während deren zweites Ende an einem Ende der Spannklappe 67 fixiert ist.67 approximately parallel to the hooked-in bend 3 of the pressure plate 2. The circular-arc-shaped end 68 is in each case pivotably mounted in a circular-arc-shaped recess 74 in the cylinder pit 62 running parallel to the axis of rotation 18. Due to the action of springs 76, the tensioning flap 67 pivots in the direction of the tensioning, rear hook-in bend 4 of the pressure plate 2. In the present example, the arcuate end 68 of the tensioning flap 67 is included provided a bore 77 in which a rod-shaped torsion spring (torsion bar spring) 76 extends. This torsion bar spring 76 is rigidly and prestressed at one end to the cylinder 1, while its second end is fixed to one end of the tensioning flap 67.
Dieser Spannklappe 67 kann, wie im beschriebenen Beispiel, achsensymmetrisch bezüglich einer Mittellinie 78 gegenüberliegend eine weitere Spannklappe 66 angeordnet sein (womit auch in entgegengesetzter Drehrichtung des Zylinders 1 produziert werden kann) oder es kann nur ein Füllstück eingesetzt sein. Zwischen diesen beiden Spannklappen 66, 67 bzw. einem Füllstück ist eine Einrichtung angebracht, die eine auf die Hebel 69 der beiden Spannklappen 66, 67 wirkende Kraft erzeugt. Im vorliegenden Beispiel ist zwischen den beiden Spannklappen ein nichtdehnbarer, aufblasbarer Schlauch 79 angeordnet.As in the example described, this tensioning flap 67 can be arranged axially symmetrically with respect to a center line 78 opposite a further tensioning flap 66 (which can also be produced in the opposite direction of rotation of the cylinder 1) or only one filler can be used. Between these two tension flaps 66, 67 or a filler, a device is attached which generates a force acting on the levers 69 of the two tension flaps 66, 67. In the present example, an inextensible, inflatable tube 79 is arranged between the two tensioning flaps.
Bei geschlossenen Spannklappen 66, 67, d. h. bei gespannter Druckplatte 2, liegt dieser Schlauch 79 flach zusammengedrückt zwischen den Spannklappen 66, 67. Wird dieser Schlauch 79 beispielsweise mit Druckluft beaufschlagt, erzeugt diese mittels der Formänderung des Schlauches 79 eine entgegen der Drehstabfeder 76 wirkende Kraft auf die Hebel 69 der Spannklappen 66, 67 und diese schwenken dadurch in Richtung der Einhängeleisten 63, 64 des Zylinders 1, wodurch der Verschluß 57 ffnet und die Einhängeabkantung 4 der Druckplatte 2 frei wird. Anhand von Fig. 2 bis Fig. 11 wird der Wechselvorgang einer Druckplatte 2 näher erläutert:When the tension flaps 66, 67 are closed, ie when the pressure plate 2 is tensioned, this hose 79 lies flat between the tension flaps 66, 67. If this hose 79 is pressurized with compressed air, for example, it generates a force acting against the torsion bar spring 76 by changing the shape of the hose 79 on the levers 69 of the tensioning flaps 66, 67 and these thereby pivot in the direction of the suspension strips 63, 64 of the cylinder 1, whereby the closure 57 opens and the suspension edging 4 of the pressure plate 2 is free. The changing process of a printing plate 2 is explained in more detail with reference to FIGS. 2 to 11:
Die Traverse 39 mit der Greif- und Andrückeinrichtung 43 wird von den beiden Linearantrieben 27, 28 von einer Parkposition in ihre Ausspannposition bewegt, während der Zylinder 1 in seine Ausspannposition dreht. Die Ausspannposition der Traverse 39 wird dadurch bestimmt, daß die Traverse 39 annähernd auf oder kurz neben einem von Drehachse 18 des Zylinders 1 auf die Gewindespindein 29, 31 der Lineareinheiten 27, 28 gefällten Lot 81 steht. Somit bestimmen in dieser Ausspannposition die später auf die Druckplatte 2 angestellten Andrückrollen 46 einen Ablösepunkt 82 der Druckplatte vom Zylinder 1 derart, daß eine im Ablösepunkt 82 angelegte Tangente 83, d. h. die Druckplatte 2, im Schacht 16 der Druckplatten-Bereitstellungseinrichtung 12 mündet. Die Ausspannposition des Zylinders 1 wird festgelegt, indem das beschriebene Lot 81 mit einer von einer Mittellinie 78 des Verschlusses 57 und der Drehachse 18 gebildeten Verbindungslinie einen Winkel von ca. 10° entgegen der Produktionsrichtung einschließt. Die Parkposition der Traverse 39 mit der Greif- und Andrückeinrichtung 43 befindet sich in der Transportebene 41 in Plattenzuführrichtung A gesehen mindestens soweit hinter dem von der Drehachse 18 des Zylinders 1 auf die Gewindespindein 29, 31 gefällten Lot 81, so daß beispielsweise manuelle Druckplattenwechsel durchgeführt werden können, z. B. ca. 100 mm - 200 mm. Die Parkposition liegt hiermit außerhalb des Plattentransportweges. Die beiden Andrückrollen 46 werden durch die Pneumatikzylinder 56 auf den Ablösepunkt 82 der Druckplatte 2 angedrückt, um ein Verrutschen der Druckplatte 2 auf dem ZylinderThe traverse 39 with the gripping and pressing device 43 is moved by the two linear drives 27, 28 from a parking position into its unclamping position, while the cylinder 1 rotates into its unclamping position. The unclamping position of the crossmember 39 is determined in that the crossmember 39 stands approximately on or shortly next to a solder 81 which has fallen onto the threaded spindle 29, 31 of the linear units 27, 28 from the axis of rotation 18 of the cylinder 1. Thus, in this unclamping position, the pressure rollers 46 later placed on the printing plate 2 determine a detachment point 82 of the printing plate from the cylinder 1 in such a way that a tangent 83 applied in the detachment point 82, ie the printing plate 2, opens into the shaft 16 of the printing plate preparation device 12. The unclamping position of the cylinder 1 is determined in that the solder 81 described forms an angle of approximately 10 ° against the production direction with a connecting line formed by a center line 78 of the closure 57 and the axis of rotation 18. The parking position of the traverse 39 with the gripping and pressing device 43 is located in the transport plane 41 in the plate feed direction A, at least as far behind the solder 81 which has fallen onto the threaded spindle 29, 31 from the axis of rotation 18 of the cylinder 1, so that manual printing plate changes are carried out, for example can, e.g. B. approx. 100 mm - 200 mm. The parking position is thus outside the plate transport path. The two pressure rollers 46 are pressed by the pneumatic cylinders 56 onto the detachment point 82 of the pressure plate 2 in order to prevent the pressure plate 2 from slipping on the cylinder
1 zu vermeiden. Daraufhin öffnet ein Verschluß 57 des Zylinders 1 und der Zylinder 1 beginnt entgegen Produktionsrichtung "P" zu drehen (Fig. 3) . Durch die Eigensteifigkeit der Druckplatte 2 federt diese aus dem Verschluß 57 heraus, welcher nach einer Drehbewegung des Zylinders 1 von ca. 10° wieder schließt.1 to avoid. Thereupon a closure 57 of the cylinder 1 opens and the cylinder 1 begins to rotate counter to the production direction "P" (FIG. 3). Due to the inherent rigidity of the pressure plate 2, it springs out of the closure 57, which closes again after a rotary movement of the cylinder 1 of approximately 10 °.
Während der Drehbewegung des Zylinders 1 wird die Druckplatte 2 reibschlüssig durch die Krafteinwirkung der Andrückrollen 46 auf dem Zylinder 1 geführt und das Druckplattenende gelangt so in den Schacht 16 des Farbwerkschutzes 11. Ca. 10° - 30° bevor die vordere Einhängeleiste 63 des Zylinders 1 die Andrückrollen 46 erreicht, stoppt der Zylinder 1 (Fig. 4) , und die Druckplatte 2 wird im Schacht 16 durch eine nicht näher dargestellte Einrichtung fixiert. Danach dreht der Zylinder 1 mindestens soweit gegen Produktionsrichtung "P", wodurch die Druckplatte 2 auf dem Zylinder 1 verschoben wird, bis durch Eigenspannung die DruckplatteDuring the rotary movement of the cylinder 1, the pressure plate 2 is frictionally guided by the force of the pressure rollers 46 on the cylinder 1 and the pressure plate end thus reaches the shaft 16 of the inking unit guard 11. Approx. 10 ° - 30 ° before the front hooking bar 63 of the cylinder 1 reaches the pressure rollers 46, the cylinder 1 stops (FIG. 4), and the pressure plate 2 is fixed in the shaft 16 by a device, not shown. Thereafter, the cylinder 1 rotates at least as far against the production direction "P", whereby the pressure plate 2 is displaced on the cylinder 1 until the pressure plate is under internal stress
2 aus der Einhängeleiste 63 herausfedert (Fig. 5) . Die Andrückrollen 46 werden mittels der Pneumatikzylinder 56 vom Zylinder 1 abgestellt.2 springs out of the hanging bar 63 (Fig. 5). The pressure rollers 46 are turned off from the cylinder 1 by means of the pneumatic cylinders 56.
Anschließend wird durch eine nicht dargestellte Einrichtung im Schacht 16 die Druckplatte 2 vom Zylinder 1 entfernt und vollständig in den Schacht 16 befördert.Then a not shown Device in the shaft 16, the pressure plate 2 removed from the cylinder 1 and completely transported into the shaft 16.
Zum Aufspannen einer neuen Druckplatte 84 dreht der Zylinder 1 in eine Aufspannposition, die dadurch bestimmt wird, daß die Mittellinie 78 des Verschlusses 57 annähernd deckungsgleich mit dem von der Drehachse 18 auf die senkrecht zur Bewegungsrichtung der Linearantriebe 27, 28 gefällten Lot 81 ist. Die Traverse 39 wird mittels der beiden Linearantriebe 27, 28 in Position zur Aufnahme der neuen Druckplatte 84 gebracht, d. h. die Saugleisten 47 stehen in Bereich des plattenzylindernahen Endes 17 der Druckplatten-Bereitstellungseinrichtung 12. Durch Belüften des Pneumatikzylinders 53 wird die Greifereinheit 44 entgegen Richtung "C" verschoben.To clamp a new pressure plate 84, the cylinder 1 rotates into a clamping position, which is determined by the fact that the center line 78 of the closure 57 is approximately congruent with the solder 81 dropped from the axis of rotation 18 onto the perpendicular 81 to the direction of movement of the linear drives 27, 28. The cross member 39 is brought into position by means of the two linear drives 27, 28 for receiving the new pressure plate 84, i. H. The suction strips 47 are located in the region of the end 17 of the pressure plate preparation device 12 near the plate cylinder. By venting the pneumatic cylinder 53, the gripper unit 44 is displaced in the direction "C".
Die neu aufzubringende Druckplatte 84 wurde auf der oberen Wand 13 und an der Einhängeleiste 19 der Druckplatten-Bereitstellungseinrichtung 12 vorpositioniert aufgelegt.The new printing plate 84 to be applied was placed in a pre-positioned manner on the upper wall 13 and on the hanging bar 19 of the printing plate preparation device 12.
Die Saugleisten 47 werden durch Entlüften des Pneumatikzylinders 54 auf das Niveau der Druckplatte 84 abgesenkt und mit Saugluft beaufschlagt (Fig. 6) . Dadurch wird die Druckplatte 84 mit ihrer druckenden Seite an der Greif- und Andrückeinrichtung 43 fixiert. Die Traverse 39 wird nun in Richtung Zylinder 1 bewegt und nach ca. 10 mm zurückgelegten Weg werden durch den Pneumatikzylinder 54 die Saugleisten 47 mit der angesaugten Druckplatte 84 angehoben.The suction strips 47 are lowered to the level of the pressure plate 84 by venting the pneumatic cylinder 54 and are subjected to suction air (FIG. 6). As a result, the printing plate 84 is fixed with its printing side to the gripping and pressing device 43. The traverse 39 is now moved in the direction of cylinder 1 and after approx. 10 mm travel through the pneumatic cylinder 54, the suction strips 47 with the suctioned pressure plate 84 are raised.
Die Traverse 39 mit Greif- und Andrückeinrichtung 43 fördert die Druckplatte 84 in Richtung vordere Einhängeleiste 63 des Zylinders 1 bis die vordere Einhängeabkantung 3 der Druckplatte 84 mit der Einhängeleiste 63 des Zylinders 1 einen Spalt "s" bildet, damit die Greifereinheit 44 mit den Saugleisten 47 die Druckplatte 84 durch den Pneumatikzylinder 54 auf die Zylindermantelfläche 22 absenken kann (Fig. 7) . Dieser Spalt s beträgt ca. 2 mm bis 5 mm.The cross member 39 with the gripping and pressing device 43 conveys the pressure plate 84 in the direction of the front mounting bar 63 of the cylinder 1 until the front mounting edge 3 of the pressure plate 84 forms a gap "s" with the mounting bar 63 of the cylinder 1, so that the gripper unit 44 with the suction bars 47 can lower the pressure plate 84 through the pneumatic cylinder 54 onto the cylinder surface 22 (FIG. 7). This gap s is approximately 2 mm to 5 mm.
Nach Absenken der Druckplatte 84 bewegen die Linearantriebe 27, 28 die Greif- und Andrückeinrichtung 43 entgegen Richtung "A" bis die vordere Einhängeabkantung 3 der Druckplatte 84 an der Einhängeleiste 63 des Zylinders 1 exakt anliegt und die Saugleisten 47 entgegen der Richtung "B" mittels der Druckfedern 49 die Druckplatte 84 mit definierter Kraft vorspannen (Fig. 8) .After the pressure plate 84 has been lowered, the linear drives 27, 28 move the gripping and pressing device 43 in the direction "A" until the front hook-in bend 3 of the pressure plate 84 lies exactly against the suspension bar 63 of the cylinder 1 and the suction strips 47 in the direction "B" by means of of the compression springs 49 bias the pressure plate 84 with a defined force (FIG. 8).
Anschließend wird die Druckplatte 84 gehalten durch die Saugleisten 47, durch Betätigen des Pneumatikzylinders 53 mit festgelegter Kraft, beispielsweise gefedert, an einen jeweiligen Seitenregisteranschlag 86 axial, parallel einer Drehachse 18 des Zylinders 1 positioniert, so daß die Druckplatte 84 sicher am Seitenregisteranschlag 86 anliegt, aber nicht verformt wird. Die Federkraft zum Positionieren der Druckplatte 84 kann beispielsweise durch die Feder eines einfach wirkenden Pneumatikzylinders 53 oder durch den Luftdruck (z. B. einstellbar über Druckregler) eines doppelt wirkenden Pneumatikzylinders erzeugt werden. Die Seitenregisteranschläge 86 sind an der Einhängeleiste 63 des Zylinders 1 unterhalb der Zylindermantelfläche 22 zylinderfest angeordnet. Im dargestellten Beispiel befindet sich ein gemeinsamer Seitenregisteranschlag 86 an einer linken bzw. rechten Seitenkante der dem jeweiligen Zylinderabschnitt zugehörigen Druckplatte 84. Die beschriebene Wirkweise des Pneumatikzylinders 53 trifft für die Anordnung des Seitenregisteranschlages 86 an der linken, Seitenkante, d. h. in Richtung C, zu, bei Anordnung des Seitenregisteranschlages 86 an der rechten Seitenkante muß der Pneumatikzylinder 53 entgegengesetzt wirken.Subsequently, the pressure plate 84 is held by the suction strips 47, by actuating the pneumatic cylinder 53 with a fixed force, for example sprung, axially positioned at a respective side register stop 86, parallel to an axis of rotation 18 of the cylinder 1, so that the pressure plate 84 rests securely on the side register stop 86, but not deformed becomes. The spring force for positioning the pressure plate 84 can be generated, for example, by the spring of a single-acting pneumatic cylinder 53 or by the air pressure (for example adjustable via pressure regulator) of a double-acting pneumatic cylinder. The side register stops 86 are arranged on the mounting rail 63 of the cylinder 1 below the cylinder surface 22 in a cylinder-fixed manner. In the example shown, there is a common side register stop 86 on a left or right side edge of the pressure plate 84 associated with the respective cylinder section. The mode of operation of the pneumatic cylinder 53 described applies to the arrangement of the side register stop 86 on the left side edge, ie in the direction C, when the side register stop 86 is arranged on the right side edge, the pneumatic cylinder 53 must act in the opposite direction.
Danach werden die beiden Andrückrollen 46 mittels der entsprechenden Pneumatikzylinder 56 auf die Druckplatte 84 abgesenkt. Die Saugluft der Saugleisten 47 wird abgestellt und durch Beaufschlagen des Pneumatikzylinders 54 mit Druckluft werden die Saugleisten 47 in Richtung "D" angehoben (Fig. 9) .The two pressure rollers 46 are then lowered onto the pressure plate 84 by means of the corresponding pneumatic cylinders 56. The suction air of the suction bars 47 is switched off and the suction bars 47 are raised in the direction “D” by applying pneumatic air to the pneumatic cylinder 54 (FIG. 9).
Hierauf dreht der Zylinder 1 in Produktionsrichtung "P" bis die Andrückrollen 46 ca. 10° - 20° vor der hinteren Einhängeabkantung 4 der Druckplatte 84 stehen, worauf der Verschluß 57 öffnet (Fig. 10) . Anschließend dreht der Zylinder 1 ca. 5° - 10° in Produktionsrichtung "P", und durch Schließen des Verschlusses 57 wird die Druckplatte 84 auf dem Zylinder 1 gespannt. Die Andrückrollen 46 werden angehoben und die Traverse 39 mit der Greif- und Andrückeinrichtung 43 fährt in die Parkposition. Dort wird der Pneumatikzylinder 54 entlüftet und die Greifereinheit 44 abgesenkt (Fig. 11) . In dieser Parkposition wird die Greif- und Andrückeinrichtung 43 von einem mindestens 3-seitig geschlossenen Schutz 87 umgeben und ist dort vor Schmutz und Farbe geschützt.Thereupon the cylinder 1 rotates in the production direction "P" until the pressure rollers 46 are approximately 10 ° to 20 ° in front of the rear hook-in bend 4 of the pressure plate 84, whereupon the closure 57 opens (FIG. 10). Then turns the cylinder 1 is approximately 5 ° -10 ° in the production direction "P", and by closing the closure 57 the pressure plate 84 is tensioned on the cylinder 1. The pressure rollers 46 are raised and the cross member 39 with the gripping and pressing device 43 moves into the park position. There the pneumatic cylinder 54 is vented and the gripper unit 44 is lowered (FIG. 11). In this parking position, the gripping and pressing device 43 is surrounded by a protection 87 which is closed on at least three sides and is protected there against dirt and paint.
Alternativ kann ein weiterer Plattenwechsel in der beschriebenen Weise vorgenommen werden. Hierzu ist die zweite Druckplatten-Bereitstellungseinrichtung 23 neben der ersten Druckplatten-Bereitstellungseinrichtung 12 angeordnet, so daß auch das zylindernahe Ende 24 der Druckplatten-Bereitstellungseinrichtung 23 zur Auflage einer zweiten, neuen Druckplatte 88 annähernd parallel zur Tangente 21 der Zylindermantelfläche 22 ausgebildet ist.Alternatively, another plate change can be made in the manner described. For this purpose, the second printing plate preparation device 23 is arranged next to the first printing plate preparation device 12, so that the end 24 of the printing plate preparation device 23 near the cylinder for supporting a second, new printing plate 88 is also formed approximately parallel to the tangent 21 of the cylinder jacket surface 22.
