Abstract

In a device for supplying printing plates (27, 67) to a plate cylinder (2) and for carrying away the printing plates (27, 67) from the printing cylinder (2), the problem consists of exchanging plates in the narrowest space without causing components of the device to prevent access to the printing rollers or make it more difficult. For this purpose, chutes (9, 11) with plate exchange guiding elements (43, 44) can be swivelled in a rest position.

Description

Die Erfindung betrifft eine Einrichtung zum Zuführen und Abführen von Druckplatten zu und von einem Plattenzylinder einer Rotationsdruckmaschine entsprechend dem Oberbegriff des Patentanspruches 1.The invention relates to a device for feeding and discharging printing plates to and from a plate cylinder of a rotary printing press according to the preamble of claim 1.

Durch die JP 61-248834 A ist eine gattungsgemäße Einrichtung zum Zuführen und Abführen von Druckplatten in Rotationsdruckmaschinen mit einem Plattenzylinder bekannt geworden. Die Zufuhr und Abfuhr der Druckplatte zum Plattenzylinder erfolgt über je einen Schacht eines längsgeteilten Speicherschachtes.JP 61-248834 A discloses a generic device for feeding and removing printing plates in rotary printing presses with a plate cylinder. The printing plate is fed to and removed from the plate cylinder via a shaft of a longitudinally divided storage shaft.

Nachteilig bei dieser Einrichtung ist, daß die Greifeinrichtung für den Druckplattenanfang und die Greifeinrichtung für das Druckplattenende jeweils exakt die übereinander angeordneten unteren Öffnungen von Zuführ- bzw. Abführschacht anfahren müssen.A disadvantage of this device is that the gripping device for the start of the printing plate and the gripping device for the end of the printing plate each have to approach the lower openings of the feed or discharge shaft arranged one above the other.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Zuführen und Abführen von Druckplatten zu und von einem Plattenzylinder zu schaffen, welche platzsparend ausgebildet ist und mit welcher in kurzer Zeit die Plattenwechselvorgänge ausgeführt werden können.The invention has for its object to provide a device for feeding and discharging printing plates to and from a plate cylinder, which is designed to save space and with which the plate changing operations can be carried out in a short time.

Erfindungsgemäß wird diese Aufgabe durch das Kennzeichen des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the characterizing part of patent claim 1.

Durch die Erfindung entstehen insbesondere folgende Vorteile. Infolge der Anordnung eines längsgeteilten Speicherschachtes ist es möglich, sowohl die abgeführte Druckplatte als auch die zuzuführende Druckplatte zwischenzulagern. Dazu sind in axialer Richtung angeordnete, sowie in den Ausfuhrschacht weisende Leitbleche vorgesehen. Der Zufuhrschacht ist gegenüber dem Führungsschacht für auszuführende Druckplatten durch einseitig federnde Leitelemente verschlossen, so daß der Zufuhrschacht und der Ausfuhrschacht in platzsparender Weise in nur einen Führungsschacht münden können, wodurch die Positionierung des Plattenzylinders hinsichtlich der Plattenab- und Plattenzuführung in nur zwei Zylinderstellungen und somit in kurzer Zeit realisiert werden kann. Diese Arbeitsschritte sind Druckende öffnen, Druckanfang entnehmen, Druckanfang Einführen, Druckende schließen.The following advantages arise in particular from the invention. As a result of the arrangement of a longitudinally divided storage shaft, it is possible to temporarily store both the removed printing plate and the printing plate to be supplied. For this purpose, baffles are provided which are arranged in the axial direction and point in the export shaft. The feed shaft is closed off from the guide shaft for printing plates to be executed by guiding elements that are resilient on one side, so that the feed shaft and the export shaft can open into only one guide shaft in a space-saving manner, as a result of which the positioning of the plate cylinder with respect to the plate discharge and plate feed in only two cylinder positions and thus in can be realized in a short time. These steps are opening the print end, removing the print start, inserting the print start, closing the print end.

Achszapfen gelagert. An einer Zugangsseite 7 zu den Zylindern 2; 3 ist die erfindungsgemäße Einrichtung vorgesehen.Axle journal mounted. On an access side 7 to the cylinders 2; 3, the device according to the invention is provided.

Die Einrichtung besteht im wesentlichen aus einem Speicherschacht 8 mit zwei Teilschächten, einem Zuführschacht 9 und einem Ausführschacht 11 sowie einem sich daran anschließenden, darunter angeordneten Führungsschacht 12 und einer Walze 13 zum Leiten und Andrücken einer Druckplatte.The device essentially consists of a storage shaft 8 with two partial shafts, a feed shaft 9 and an outlet shaft 11, as well as an adjoining guide shaft 12 arranged underneath and a roller 13 for guiding and pressing a printing plate.

Der Speicherschacht 8 weist eine Vorderwand 14 und eine Rückwand 16 auf, die zueinander parallel verlaufen und durch nicht dargestellte Seitenbleche an den Stirnseiten 17; 18 miteinander verbunden sind. Der Zuführschacht 9 und der Ausführschacht 11 ist durch eine parallel zu den Wänden 14; 16 verlaufende Zwischenwand 19 getrennt, welche den Speicherschacht 8 von einem ersten Ende 21 zu einem zweiten Ende 22 durchläuft. Am zweiten Ende 22 des Speicherschachtes 8 endet die Zwischenwand 19 an oder in einer in axialer Richtung zu den Zylindern 2; 3 verlaufenden Leiste 23, die an den Seitenblechen der Stirnseiten 17; 18 des Speicherschachtes 8 befestigt ist (Fig. 3). Diese Leiste 23 trennt den Speicherschacht 8 von dem Führungsschacht 12, d. h. an dieser Stelle endet der Speicherschacht 8 und beginnt der Führungsschacht 12. Der Führungsschacht 12 wird ebenfalls durch die in Richtung Walzen 2; 3 verlaufende Vorderwand 14 sowie Rückwand 16 und Seitenblechen an den Stirnseiten 17; 18 gebildet. Demzufolge verläuft der Führungsschacht 12 von der Leiste 23 aus in einer leicht gekrümmten Form in Richtung Plattenzylinder 2 mit einem Radius, der etwa dem Radius des Plattenzylinders 2 entspricht, bis kurz vor einer axial verlaufenden Mantellinie am Plattenzylinder 2 unterhalb seiner Drehachse 24. Die Leiste 23 weist Leitelemente oder Leitbleche 28 bis 36 auf, die jeweils streifenförmig ausgebildet sein können und aus Federstahl bestehen können. Die Leitbleche 28 bis 30 sind als Haltebleche ausgeführt und verlaufen in radialer Richtung zum Plattenzylinder 2 bzw. quer zur Bewegungsrichtung B einer neuen, zuzuführenden Druckplatte 27, liegen mit ihren Enden 39 innen an der Vorderwand 14 an, und sind bei Belastung mit ihren beiden Enden 39 um die Leiste 23 in Richtung C schwenkbar. Durch die Betätigung der Druckplatte 27 in Pfeilrichtung B werden die drei in axialer Richtung voneinander beabstandeten streifenförmigen Leitbleche 28; 29; 30 in Pfeilrichtung C verschwenkt und lassen die Druckplatte 27 in dieser Richtung passieren. An der Leiste 23 sind weiterhin Leitbleche 31; 32; 33 angeordnet, die zwischen der Vorderwand 14 und der Rückwand 16 verlaufen, sich in Richtung Plattenzylinder 2 erstrecken und mit ihren Enden 40 innen an der Vorderwand 14 des Führungsschachtes 12 anliegen. Somit wirken die Leitbleche 31 bis 33 als einseitig rückfedernde Weichen, die den Zuführschacht 9 für Druckplatten nur in einer Richtung C passierbar machen und für aus Richtung D vom Zuführschacht 9 kommende, vom Plattenzylinder 2 abgenommene Druckplatten verschließen. Weiterhin weisen die ebenfalls an der Leiste 23 befestigten Leitbleche 34 bis 36 in Richtung erstes Ende 21 des Speicherschachtes 8 und liegen mit ihrem Ende 41 an der Innenseite der Rückwand 16 an, so daß der Ausfuhrschacht 11 von seinem ersten Ende 21 her gesehen verschlossen ist. Somit kann eine aus Pfeilrichtung D vom Plattenzylinder 2 kommende Druckplatte nach Passieren der Leitbleche 34 bis 36 auf diesen bis zur Entnahme aus dem Ausfuhrschacht 11 abgestellt werden. Die Leitbleche 34 bis 36 dienen somit als Sperrelement gegen die in diesen Ausfuhrschacht 11 versehentlich eingeführeter Druckplatten 27 und somit als Einwegpassage für auszuführende Druckplatten.The storage shaft 8 has a front wall 14 and a rear wall 16, which run parallel to one another and through side plates, not shown, on the end faces 17; 18 are connected. The feed shaft 9 and the feed shaft 11 is through a parallel to the walls 14; 16 extending partition 19 separated, which passes through the storage shaft 8 from a first end 21 to a second end 22. At the second end 22 of the storage shaft 8, the intermediate wall 19 ends at or in an axial direction to the cylinders 2; 3 extending strip 23, which on the side plates of the end faces 17; 18 of the storage shaft 8 is attached (Fig. 3). This bar 23 separates the storage shaft 8 from the guide shaft 12, ie the storage shaft 8 ends at this point and the guide shaft 12 begins. The guide shaft 12 is likewise moved in the direction of the rollers 2; 3 extending front wall 14 and rear wall 16 and side plates on the end faces 17; 18th educated. As a result, the guide shaft 12 runs from the bar 23 in a slightly curved shape in the direction of the plate cylinder 2 with a radius that corresponds approximately to the radius of the plate cylinder 2 until shortly before an axially extending surface line on the plate cylinder 2 below its axis of rotation 24. The bar 23 has guide elements or guide plates 28 to 36, which can each be formed in strips and can consist of spring steel. The baffles 28 to 30 are designed as holding plates and run in the radial direction to the plate cylinder 2 or transversely to the direction of movement B of a new pressure plate 27 to be supplied, their ends 39 lie against the inside of the front wall 14, and are under load with their two ends 39 can be pivoted about the bar 23 in the direction C. By actuating the pressure plate 27 in the direction of arrow B, the three strip-shaped guide plates 28; 29; 30 pivoted in the direction of arrow C and let the pressure plate 27 pass in this direction. On the bar 23 baffles 31 are still; 32; 33 arranged, which run between the front wall 14 and the rear wall 16, extend in the direction of the plate cylinder 2 and their ends 40 rest against the inside of the front wall 14 of the guide shaft 12. Thus, the guide plates 31 to 33 act as one-way resilient switches, which make the feed shaft 9 for printing plates passable only in one direction C and for printing plates coming from the feeding shaft 9 coming from direction D and removed from the plate cylinder 2 close. Furthermore, the guide plates 34 to 36 also fastened to the bar 23 point in the direction of the first end 21 of the storage shaft 8 and rest with their end 41 on the inside of the rear wall 16, so that the export shaft 11 is closed from its first end 21. Thus, a pressure plate coming from the direction of the arrow D from the plate cylinder 2 after passing the guide plates 34 to 36 can be placed thereon until it is removed from the export shaft 11. The baffles 34 to 36 thus serve as a blocking element against the printing plates 27 which are inadvertently inserted into this discharge shaft 11 and thus as a one-way passage for printing plates to be carried out.

Die Leitbleche 28 bis 30, 31 bis 33 und 39 bis 41 können auch einstückig d. h. durchgängig ausgeführt sein. Die Leitbleche 28 bis 30, in radialer Richtung angeordnet, können entfallen, wenn die Zuhaltekraft der als Weiche wirkenden Leitbleche 31 bis 33 so groß bemessen ist, daß eine zwischen der Innenseite der Vorderwand 14 und den Enden 40 der Leitbleche 31 bis 33 anliegende Druckplatte die Leitbleche 31 bis 33 nur gegen die Wirkung einer zusätzlich aufzuwendenden Kraft in Richtung C passiert.The baffles 28 to 30, 31 to 33 and 39 to 41 can also be made in one piece d. H. be carried out consistently. The guide plates 28 to 30, arranged in the radial direction, can be omitted if the locking force of the guide plates 31 to 33 acting as a switch is dimensioned so large that a pressure plate lying between the inside of the front wall 14 and the ends 40 of the guide plates 31 to 33 Baffles 31 to 33 only happen in the direction C against the action of an additional force.

Weiterhin könnte die sich in axialer Richtung erstreckende Leiste 23 eine sich ebenfalls in axialer Richtung erstreckende Rotationsachse aufweisen, um welche die Leiste 23 schwenkbar ausgebildet ist. Dabei könnten die Leitbleche 28 bis 30 entfallen und die Leitbleche 31 bis 33 sowie 34 bis 36 könnten aus nichtfederndem Material hergestellt und gegen die Kraft von Federn, z. B. Zugfedern, an die Innenseiten der Vorderwand 14 bzw. der Rückwand 16 andrückbar sein, so daß insgesamt wiederum eine federnde Anstellung der Leitbleche 31 bis 36 erzielt würde.Furthermore, the bar 23 extending in the axial direction could have an axis of rotation, likewise extending in the axial direction, about which the bar 23 is designed to be pivotable. The guide plates 28 to 30 could be omitted and the guide plates 31 to 33 and 34 to 36 could be made of non-resilient material and against the force of springs, e.g. B. tension springs, can be pressed against the inner sides of the front wall 14 and the rear wall 16, so that overall a resilient employment of the guide plates 31 to 36 would be achieved.

Innerhalb des Führungsschachtes 12 und kurz vor dessen Auslauf in Richtung Plattenzylinder 2 sind in der Nähe der Stirnseiten 17; 18 Leitelemente 43; 44 angebracht, deren Dicke dem Abstand zwischen Vorderwand 14 und Rückwand 16 entsprechen. Ein Abstand e der Leitelemente 43; 44 zueinander (Fig. 2) entspricht der Breite einer Druckplatte 27. Die Leitelemente 43; 44 weisen an den einander zugewandten Seiten Abrundungen oder Abschrägungen 46 auf, die ein Zentrieren der Druckplatte 27 beim Ausführen vom Plattenzylinder 2 zum Führungsschacht 12 in Pfeilrichtung D ermöglichen. Dies gilt ebenfalls für ein Zentrieren beim Zuführen der Druckplatte 27 vom Führungsschacht 12 zum Plattenzylinder 2 in Pfeilrichtung C. Die im Führungsschacht 12 angeordneten Leitelemente 43; 44 weisen in Pfeilrichtung C gesehen, ein erstes Ende 47 und ein zweites Ende 48 auf.Within the guide shaft 12 and shortly before its outlet in the direction of the plate cylinder 2 in the vicinity of the end faces 17; 18 guide elements 43; 44 attached, the thickness of which corresponds to the distance between front wall 14 and rear wall 16. A distance e between the guide elements 43; 44 to each other (FIG. 2) corresponds to the width of a pressure plate 27. The guide elements 43; 44 have roundings or bevels 46 on the sides facing one another, which enable the pressure plate 27 to be centered when the plate cylinder 2 is guided toward the guide shaft 12 in the direction of arrow D. This also applies to centering when feeding the pressure plate 27 from the guide shaft 12 to the plate cylinder 2 in the direction of the arrow C. The guide elements 43; 44 have a first end 47 and a second end 48 as seen in the direction of arrow C.

Entsprechend den Darstellungen nach Fig. 1, 2 und 4 ist die Walze 13 gezeigt, welche aus einer Gummirolle 49 besteht, die auf einer Achse 51 drehbar gelagert ist. Die Gummirolle 49 kann auch wie in Fig. 2 gezeigt, in axialer Richtung unterteilt sein und z. B. aus drei Einzelrollen 49 bestehen. Die Achse 51 ist beiderseits in zweiarmigen Hebeln 52; 53 gelagert, welche eine Lagerstelle 54; 56 etwa mittig an der Stirnseite 17; 18 des Führungsschachtes 12 aufweisen. Erste Arme 57 der Hebel 52; 53 tragen die Achse 51 und zweite Arme 58 sind über Gelenke 59 und Kolbenstangen 61 mit jeweils an den Stirnseiten 17; 18 des Führungsschachtes 12 befestigten Positionierelementen 62; 63 , z. B. doppelt wirkenden Pneumatikzylindern, verbunden.1, 2 and 4, the roller 13 is shown, which consists of a rubber roller 49 which is rotatably mounted on an axis 51. The rubber roller 49 can also be divided as shown in Fig. 2, in the axial direction and z. B. from three individual roles 49 exist. The axis 51 is on both sides in two-armed levers 52; 53 stored, which a bearing 54; 56 approximately in the middle of the end face 17; 18 of the guide shaft 12. First arms 57 of the levers 52; 53 support the axis 51 and second arms 58 are via joints 59 and piston rods 61, each on the end faces 17; 18 of the guide shaft 12 attached positioning elements 62; 63, e.g. B. double-acting pneumatic cylinders connected.

Entsprechend Fig. 1, 4 und 5 weist der Plattenzylinder 2 bekannte Plattenklemm- und Spannvorrichtungen 64; 66 in einer Zylindergrube auf, so wie diese z. B. in der DE-OS 36 04 071 beschrieben sind, um eine Druckplatte 67 aufzuspannen. Dazu sind ebenfalls bekannte Klemmleisten oder Klemmklappen 68; 69 vorgesehen. Die Betätigung der vorgenannten Klemm- und Spanneinrichtungen kann mittels eines Arbeitsmediums z. B. Druckluft erfolgen, welches über eine Dreheinführung am Wellenzapfen des Plattenzylinders 2 zugeführt wird.1, 4 and 5, the plate cylinder 2 has known plate clamping and clamping devices 64; 66 in a cylinder pit, like this z. B. are described in DE-OS 36 04 071 to clamp a pressure plate 67. Known terminal strips or clamping flaps 68; 69 provided. The actuation of the aforementioned clamping and clamping devices can be done by means of a working medium, for. B. Compressed air, which is supplied via a rotary entry on the shaft journal of the plate cylinder 2.

Entsprechend den Darstellungen in Fig. 2 und 4 sind auf der Achse 51 in unmittelbarer Nähe der Hebel 52; 53 auf der Achse 51 feststellbare Exzenterscheiben 71; 72 angeordnet, die jeweils mit am Plattenzylinder 2 befindlichen festen Anschlägen 73; 74 zusammenwirken.According to the representations in FIGS. 2 and 4, the levers 52; 53 eccentric discs 71; 72 arranged, each with fixed stops 73 on the plate cylinder 2; 74 cooperate.

Diese Exzenterscheiben 71; 72 laufen im Falle der Anstellung der Gummirolle 49 an den Plattenzylinder 2 in am Umfang des Plattenzylinders 2 jeweils in der Nähe seiner Stirnflächen verlaufenden Nuten 76; 77, ohne jedoch den Nutgrund zu berühren. Diese Nuten 76; 77 können auch in jeweils stirnseitig am Plattenzylinder 2 befestigten Schmitzringen enthalten sein.These eccentric discs 71; 72 run in the case of employment of the rubber roller 49 on the plate cylinder 2 in on the circumference of the plate cylinder 2 in each case in the vicinity of its end faces grooves 76; 77, but without touching the bottom of the groove. These grooves 76; 77 can also be contained in bearers attached to the end of the plate cylinder 2.

Entsprechend der Darstellung in Fig. 4 ist in den Nuten 76; 77 jeweils ein Anschlag 73; 74 (nur 74 dargestellt) in Produktionsdrehrichtung F des Plattenzylinders 2 gesehen, am Anfang der Plattenklemm- und Spanneinrichtung 64 für den Plattenanfang angeordnet, so daß an dieser Stelle bei einer Zuführstellung G der Platte 27 nach Fig. 4 die Exzenterscheiben 71; 72 in Eingriff sind mit den Anschlägen 73; 74, so daß ein definierter Spalt mit dem Betrag h zwischen der Gummitrolle 49 und der Mantelfläche des Plattenzylinders 2 gebildet wird.4, in the grooves 76; 77 each have a stop 73; 74 (only 74 shown) seen in the direction of production F of the plate cylinder 2, arranged at the beginning of the plate clamping and tensioning device 64 for the plate start, so that at this point the eccentric discs 71; 72 are engaged with the stops 73; 74, so that a defined gap with the amount h is formed between the rubber roller 49 and the outer surface of the plate cylinder 2.

Die Funktionsweise der Einrichtung ist wie folgt. Entsprechend einer Abführstellung K der auf dem Plattenzylinder 2 befindlichen Druckplatte 67 nach Fig. 1, ist die Plattenklemm- und Spanneinrichtung 64; 66 in Ruhestellung und die Klemmleiste 69 hat das Plattenende 78 der Druckplatte 67 freigegeben. Die Walzenvorrichtung 13 befindet sich in der Abführstellung K, d. h. die Gummirolle 49 weist eine maximale Entfernung l vom Plattenzylinder 2 auf, bzw. zwischen Gummirolle 49 und Plattenzylinder 2 besteht ein Spalt mit der Weite l. Das Plattenende 78 entspannt sich nun in eine radiusferne Stellung vom Plattenzylinder 2 und federt dabei gegen die Gummirolle 49. Durch Drehen des Plattenzylinders 2 im Uhrzeigersinn entsprechend Drehrichtung M nach Fig. 1, wirkt die Gummirolle 49 als Leitorgan. Durch Weiterdrehen des Plattenzylinders 2 in Drehrichtung M gelangt das Plattenende 78 in den Führungsschacht 12 und passiert die Leitelemente 43; 44 zwischen ihren Enden 47; 48, die das Plattenende 78 mittels der Abrundungen 46 zentrieren. Wenn die Druckplatte 67 somit im Führungsschacht 12 sicher geführt ist, dann werden die Positionierelemente oder Arbeitszylinder 62;
63 angestellt, so daß Gummirolle 49 den Spalt l schließt (l = 0) und an der Druckplatte 67 anliegt. Das entspricht einer Andrückstellung N, so wie diese in Fig. 5 gezeigt ist. Infolge Weiterdrehens des Plattenzylinders 2 in Abführdrehrichtung M nach Fig. 1 wird die Druckplatte 67 in Richtung Speicherschacht 8 befördert und passiert nunmehr die Leitbleche 31 bis 33 (Fig. 3), die in Pfeilrichtung D den Zuführschacht 9 verschließen und das Plattenende 78 in Richtung Ausführschacht 11 leiten, bis dieses die in den Ausführschacht 11 weisenden Leitbleche 34 bis 36 berührt und deren Ende 41 in Richtung Zwischenwand 19 wegschwenkt, so daß die Druckplatte 67 vollends in den Ausführschacht 11 gelangt.
The device works as follows. Corresponding to a discharge position K of the pressure plate 67 on the plate cylinder 2 according to FIG. 1, the plate clamping and tensioning device 64; 66 in the rest position and the terminal block 69 has released the plate end 78 of the pressure plate 67. The roller device 13 is in the discharge position K, ie the rubber roller 49 has a maximum distance l from the plate cylinder 2, or between the rubber roller 49 and plate cylinder 2 there is a gap with the width l. The plate end 78 now relaxes in a position remote from the radius of the plate cylinder 2 and springs against it the rubber roller 49. By rotating the plate cylinder 2 clockwise in the direction of rotation M according to FIG. 1, the rubber roller 49 acts as a guide element. By turning the plate cylinder 2 further in the direction of rotation M, the plate end 78 reaches the guide shaft 12 and passes the guide elements 43; 44 between its ends 47; 48, which center the plate end 78 by means of the roundings 46. If the pressure plate 67 is thus securely guided in the guide shaft 12, then the positioning elements or working cylinders 62;
63 turned on, so that rubber roller 49 closes the gap l (l = 0) and rests on the pressure plate 67. This corresponds to a pressure position N, as shown in FIG. 5. 1, the pressure plate 67 is conveyed in the direction of the storage shaft 8 and now passes the guide plates 31 to 33 (FIG. 3), which close the feed shaft 9 in the direction of arrow D and the plate end 78 in the direction of the discharge shaft 11 conduct until it touches the guide plates 34 to 36 pointing into the delivery shaft 11 and the end 41 thereof pivots away in the direction of the intermediate wall 19, so that the pressure plate 67 reaches the delivery shaft 11 completely.

Die Maschine positioniert bis in Zuführstellung G, öffnet die Klemmleiste 68 für den Plattenanfang 11 und stoppt. Das Plattenende 78 ragt nunmehr aus dem Ausführschacht 11 und kann vom Bedienpersonal soweit herausgezogen werden, bis der Plattenanfang die Enden 41 der Leitbleche 34; 35; 36 passiert hat. Diese Leitbleche 34 bis 36 federn nun zurück und verriegeln den Ausführschacht 11.The machine positions up to the feed position G, opens the terminal strip 68 for the start of the plate 11 and stops. The plate end 78 now protrudes from the chute 11 and can be pulled out by the operating personnel until the beginning of the plate ends 41 of the guide plates 34; 35; 36 happened. These guide plates 34 to 36 now spring back and lock the delivery shaft 11.

Der Plattenzylinder 2 befindet sich immer noch in Zuführstellung G nach Fig. 4. Eine bereits in den Zuführschacht 9 eingebrachte Druckplatte 27 liegt mit ihrem Druckanfang 79 auf dem Ende 39 der in radialer Richtung angeordneten Leitbleche 28 bis 30 in Wartestellung. Durch die Wirkung einer Kraft auf die Druckplatte 27 schwenken die Leitelemente 28 bis 30 um die Leiste 23 und der Druckanfang 79 der Druckplatte 27 stößt in Bewegungsrichtung C gegen die Leitbleche 31 bis 33 und gelangt somit in den Führungsschacht 12. Weiterführend passiert der Druckanfang 79 die Leitelemente 43; 44 mit ihren Enden 47; 48 sowie Abschrägungen 46. Die Druckplatte wird zentriert und gelangt nach Fig. 4 über den Spalt h, der zwischen der Peripherie der Gummirolle 49 und der Peripherie des Plattenzylinders 2 gebildet ist, in die Klemmleiste 68. Der Anfang 79 der Druckplatte 27 wird dort über bekannte Paßsysteme exakt positioniert. Die Klemmleiste 68 wird nun auf ein Tastersignal oder Sensorsignal hin geschlossen und nach einem weiteren Tastersignal dreht sich der Plattenzylinder 2 entgegen dem Uhrzeigersinn in Produktionsdrehrichtung F.The plate cylinder 2 is still in the feed position G according to FIG. 4. A pressure plate 27 which has already been introduced into the feed shaft 9 is in the waiting position with its pressure start 79 on the end 39 of the guide plates 28 to 30 arranged in the radial direction. Due to the action of a force on the pressure plate 27, the guide elements 28 to 30 swivel around the bar 23 and the start of pressure 79 of the pressure plate 27 abuts against the guide plates 31 to 33 in the direction of movement C and thus reaches the guide shaft 12 Guide elements 43; 44 with their ends 47; 48 and bevels 46. The pressure plate is centered and, according to FIG. 4, reaches the clamping strip 68 via the gap h, which is formed between the periphery of the rubber roller 49 and the periphery of the plate cylinder 2. The beginning 79 of the pressure plate 27 is there known passport systems positioned exactly. The terminal strip 68 is now closed in response to a button signal or sensor signal and, after a further button signal, the plate cylinder 2 rotates counterclockwise in the direction of production F.

Die Exzenterscheiben 71; 72 gleiten nunmehr von den Anschlägen 73; 74 und laufen weiterhin in den Nuten 76; 77, so daß die Gummirolle 49 die Druckplatte 27 mittels der Arbeitszylinder 62; 63 fest auf die Mantelfläche des Plattenzylinders 2 drückt (Fig. 5). Der Plattenzylinder 2 dreht sich nunmehr solange, bis die Klemmleiste 69 in die Nähe der Gummirolle 49, d. h. in Abführstellung K, kommt. Danach schließt die Klemmleiste 69 und die Positionierelemente 62; 63 stellen die die Gummirolle 49 ab, d. h. sie bringen diese in die Abführstellung K nach Fig. 1. Die Druckplatte 27 wird mittels der Plattenklemm- und Spannvorrichtungen 64; 66 gespannt. Der Plattenwechselvorgang ist nunmehr beendet. Die Positionierelemente 62; 63 können als pneumatische Arbeitszylinder ausgebildet sein.The eccentric discs 71; 72 now slide from the stops 73; 74 and continue to run in the grooves 76; 77, so that the rubber roller 49 by means of the pressure plate 27 the working cylinder 62; 63 firmly presses on the outer surface of the plate cylinder 2 (Fig. 5). The plate cylinder 2 now rotates until the terminal block 69 comes close to the rubber roller 49, ie in the discharge position K. Then the terminal block 69 and the positioning elements 62; 63 turn off the rubber roller 49, ie they bring it into the discharge position K according to FIG. 1. The pressure plate 27 is by means of the plate clamping and tensioning devices 64; 66 excited. The plate changing process is now complete. The positioning elements 62; 63 can be designed as pneumatic working cylinders.

Entsprechend den Darstellungen in Fig. 1 und 2 ist die aus dem Speicherschacht 8, dem weiterführenden Führungsschacht 12 und der am Führungsschacht 12 befindlichen Walzenvorrichtung 13 bestehende Einrichtung als eine biegesteife Einheit 81 zu betrachten, die im Falle der Nichtbenutzung, d. h. in Ruhestellung vor beide Zylinder 2; 3, d. h. vor den Plattenzylinder 2 und vor den Gummizylinder 3 verschwenkbar ist. Dies geschieht dadurch, daß an den Stirnseiten 17; 18 der Einheit 81 jeweils oben und unten Gelenke 82 bis 85 befestigt sind, die jeweils über Koppeln 87 bis 90 mit gestellfesten Gelenken 92 bis 95 verbunden sind. Der Antrieb erfolgt über einen gestellfesten Arbeitszylinder 97, z. B. Pneumatikzylinder, welcher über seine Kolbenstange und einem Gelenk 98 und einem Hebel 99 fest mit der in der Lagerung 95 befindlichen Koppel 90 verbunden ist.According to the representations in FIGS. 1 and 2, the device consisting of the storage shaft 8, the further guide shaft 12 and the roller device 13 located on the guide shaft 12 is to be regarded as a rigid unit 81 which, when not in use, ie in the rest position, in front of both cylinders 2; 3, ie in front of the plate cylinder 2 and in front of the rubber cylinder 3 is pivotable. This is done in that on the end faces 17; 18 of the unit 81, joints 82 to 85 are fastened at the top and bottom, which are each connected via couplers 87 to 90 to joints 92 to 95 fixed to the frame. The drive takes place via a frame-fixed working cylinder 97, z. B. pneumatic cylinder, which is connected via its piston rod and a joint 98 and a lever 99 with the coupling 90 located in the bearing 95.

Die Koppel 90 ist mit einer Lagerung als Winkelhebel ausgeführt, der über einen ersten Schenkel mit dem Gelenk 85 und über einen zweiten Schenkel mit dem an der Kolbenstange des Arbeitszylinders 97 befindlichen Gelenk 98 verbunden ist. Durch Betätigen des Arbeitszylinders 97 ist die Einheit 81 entsprechend der in Fig. 1 gestrichelt dargestellten Schwenkkurven 101, 102 um die Gelenke 92; 93 und 94; 95 in Richtung Maschinenfundament verschwenkbar.The coupling 90 is designed with a bearing as an angle lever, which is connected to the joint 85 via a first leg and to the joint 98 located on the piston rod of the working cylinder 97 via a second leg. By actuating the working cylinder 97, the unit 81 is corresponding to the pivot curves 101, 102 shown in broken lines in FIG. 1 about the joints 92; 93 and 94; 95 can be swiveled towards the machine foundation.

Nach einer weiteren in Fig. 6 und 7 dargestellten Ausführungsform ist der Speicherschacht 8 und der Führungsschacht 12 voneinander trennbar angeordnet.According to a further embodiment shown in FIGS. 6 and 7, the storage shaft 8 and the guide shaft 12 are arranged to be separable from one another.

Dazu sind für den Führungsschacht 12 an gestellfesten Lagern 94; 95 Streben 103; 104 angebracht, die fest mit den Stirnseiten 17; 18 des Speicherschachtes 8 verbunden sind. Die Stirnseiten 17; 18 des Führungsschachtes 12 sind weiterhin über ihre gesamte Länge mit Streben 106; 107 verbunden, die in den Gelenken 94; 95 gestellfest gelagert sind. Die Streben 106; 107 sind an den den Gelenken 94; 95 abgewandten Enden durch Verriegelungselemente 108; 109 mit den Streben 103; 104 verbindbar. Die Verriegelungselemente 108; 109 bestehen jeweils aus einem Winkel 111, welcher mit der Stirnseite eines in axialer Richtung verlaufenden Schenkels an der Strebe 106; 107 befestigt, z. B. verschweißt ist. Parallel zu diesem sich in axialer Richtung erstreckenden Schenkel ist ein Stift 112 angeordnet, der einerseits in einer Bohrung des zweiten Schenkels des Winkels 111 und andererseits in einer Bohrung der Strebe 106; 107 gelagert ist. Gegen die Kraft einer Druckfeder 113, welche auf dem Stift 112 angeordnet ist, und sich am zweiten Schenkel des Winkels 111 abstützt und gegen eine auf dem Stift 112 befestigte Scheibe 114 drückt, wird das Verriegelungselement 108; 109 permanent in Verriegelungsstellung gehalten, d. h. der Stift 111 greift in eine Bohrung der Strebe 103; 104 ein, so daß die Streben 103; 104 mit den Streben 106; 107 trennbar verbunden sind. Am strebenfernen Ende ist der Stift 112 mit einer Handhabe 116, z. B. mit einem Griff, ausgestattet. Dadurch ist es möglich, die ungetrennten Schächte 8; 12 analog der Einheit 81 nach der Darstellung in Fig. 1 mittels des Arbeitszylinders 97 entsprechend den gestrichelt dargestellten Schwenkkurven 101; 102 um die Gelenke 92; 93 und 94; 95 in Richtung Maschinenfundament zu verschwenken.For this purpose, for the guide shaft 12 on bearings 94; 95 struts 103; 104 attached, which is fixed to the end faces 17; 18 of the storage shaft 8 are connected. The end faces 17; 18 of the guide shaft 12 are still over their entire length with struts 106; 107 connected in the joints 94; 95 are fixed to the frame. The struts 106; 107 are on the joints 94; 95 opposite ends by locking elements 108; 109 with the struts 103; 104 connectable. The locking elements 108; 109 each consist of an angle 111, which with the end face of a leg extending in the axial direction on the strut 106; 107 attached, e.g. B. is welded. Parallel to this is in the axial direction extending leg is a pin 112 which is on the one hand in a bore of the second leg of the angle 111 and on the other hand in a bore of the strut 106; 107 is stored. Against the force of a compression spring 113, which is arranged on the pin 112 and is supported on the second leg of the angle 111 and presses against a disk 114 fastened on the pin 112, the locking element 108; 109 permanently held in the locked position, ie the pin 111 engages in a bore in the strut 103; 104 so that the struts 103; 104 with struts 106; 107 are separably connected. At the end remote from the strut, the pin 112 is provided with a handle 116, e.g. B. equipped with a handle. This makes it possible for the undivided shafts 8; 12 analogous to the unit 81 as shown in FIG. 1 by means of the working cylinder 97 in accordance with the swivel curves 101 shown in dashed lines; 102 around the joints 92; 93 and 94; 95 in the direction of the machine foundation.

Es ist jedoch auch möglich, durch Betätigen der Stifte 112 der Verriegelungselemente 108; 109 die Streben 103; 104 von den Streben 106; 107 zu trennen, d. h. zu entriegeln, so daß die Streben 103; 104 ihre Lage beibehalten, und die mit den Stirnseiten 17; 18 des Führungsschachtes 12 fest verbundenen Streben 106; 107, die gleichzeitig die Walzeneinrichtung 13 mit aufnehmen, sind um die gestellfesten Gelenke 94; 95 nach einer gestrichelt dargestellten Schwenkkurve 117 gegen einen gestellfesten Anschlag 118 schwenkbar. Somit ist der Plattenzylinder 2 zugänglich, indem das Bedienpersonal zwischen den Streben 103; 104 hindurch an diesem Zylinder hantieren kann.However, it is also possible to actuate the pins 112 of the locking elements 108; 109 the struts 103; 104 of the struts 106; 107 to separate, ie to unlock, so that the struts 103; 104 maintain their position, and the end faces 17; 18 of the guide shaft 12 fixed struts 106; 107, which also accommodate the roller device 13, are about the frame-fixed joints 94; 95 according to a dashed curve 117 against one frame-fixed stop 118 swiveling. The plate cylinder 2 is thus accessible by the operating personnel between the struts 103; 104 can handle this cylinder.

Es ist jedoch auch möglich, die Einheit 81 ohne die gestrichelt in Fig. 1 dargestellten Schwenkkurven 101; 102 in Richtung Maschinenfundament ohne Abstandsänderung zum Seitengestell 4 vertikal dadurch zu bewegen, daß z. B. die Gelenke 82, 84 und 83, 85 in vertikal angeordneten Parallelführungen gleiten. Der Antrieb könnte durch einen Pneumatikzylinder erfolgen.However, it is also possible to use the unit 81 without the swivel curves 101; 102 in the direction of the machine foundation without changing the distance to the side frame 4 vertically by z. B. the joints 82, 84 and 83, 85 slide in vertically arranged parallel guides. The drive could be done by a pneumatic cylinder.

Die Positionierelemente 62; 63 können als Stellmotore oder als pneumatische Stellzylinder ausgebildet sein, die mehrere voreingestellte Positionen anfahren.The positioning elements 62; 63 can be designed as servomotors or as pneumatic actuating cylinders, which move to several preset positions.
