Description

Vorrichtung am Formzylinder von Rotationsdruckmaschinen zum Befestigen gebogener Stereotypieplatten Zusatz zum Patent: 1090 233 Die Erfindung betrifft eine Vorrichtung am Formzylinder von Rotationsdruckmaschinen zum Befestigen gebogener Stereotypieplatten, die an der Unterseite längs der beiden zur Zylindermittelachse parallelen Plattenkanten Ausnehmungen aufweisen, in die je eine Reihe von Haken greift, von denen die eine Hakenreihe mittels einer Nockenwelle und die andere unter Federbelastung um den von den in die Plattenausnehmungen greifenden Hakenkanten abgewandten Hakenfuß schwenkbar ist, nach Patent 1090 233.Device for attaching to the forme cylinder of rotary printing machines bent stereotype plates Patent amendment: 1090 233 The invention relates to a device on the forme cylinder of rotary printing presses for attaching curved ones Stereotype plates attached to the bottom along the two to the cylinder center axis parallel plate edges have recesses, in each of which a row of hooks engages, of which a row of hooks by means of a camshaft and the other under Spring loading around the hook edges reaching into the panel recesses remote hook foot is pivotable, according to patent 1090 233.

Bei dieser bekannten Vorrichtung bedarf es jedoch einer besonders genauen Bearbeitung, um die einzelnen Taschen genau fluchtend in der Platte anbringen zu können und damit ein sattes Anliegen der Haken in den Taschen zu bewirken.In this known device, however, there is a special need precise machining in order to fit the individual pockets exactly in alignment in the plate to be able to and thus to cause a full concern of the hooks in the pockets.

Um diesen Mangel zu beheben, wird nach der Erfindung vorgeschlagen, zwischen der Nockenwelle und den von ihr betätigten Haken an diesen federnd abgestützte, im Plattenzylinder schwenkbar gelagerte Druckstücke anzuordnen, in denen die Haken an ihrem Fuß um ihre parallel zur Zylindermittelachse verlaufende Querachse schwenkbar gelagert sind. Durch diese Maßnahme kann die Nockenwelle so lange verdreht werden, bis alle Haken auf den Grund der Nut reichen, da bei den in die weniger tiefen Nuten greifenden Haken die Feder zwischen Haken und Nockenwelle zusammengedrückt wird, solange noch nicht alle benachbarten Haken anliegen. Zudem ermöglicht die Verschwenkbarkeit der Haken um ihre Querachse das einwandfreie Anliegen der Haken, auch bei nicht genau achsparallelem Verlauf der Taschen. Für die Bearbeitung der Taschen ist daher weniger Sorgfalt erforderlich.In order to remedy this deficiency, it is proposed according to the invention, between the camshaft and the hooks actuated by it, resiliently supported on these, to arrange pivotably mounted pressure pieces in the plate cylinder, in which the hooks pivotable at its foot about its transverse axis running parallel to the cylinder center axis are stored. This measure allows the camshaft to be rotated as long as until all the hooks reach the bottom of the groove, since the ones in the less deep grooves gripping hook the spring is compressed between the hook and the camshaft, as long as not all of the neighboring hooks are in contact. In addition, it can be pivoted the hook around its transverse axis the perfect fit of the hook, even if not exactly axially parallel course of the pockets. For the processing of the pockets is therefore less care required.

Es ist zwar schon bekannt, die Spannhaken von Stereotypieplattenaufspannvorrichtungen federnd gegen ihr Betätigungselement abzustützen. Neben dem erheblichen Aufwand durch Verwendung kniehebelartig wirkender Lenker, die durch ein elastisches Druckorgan gekuppelt sind, ist bei dieser Ausführung wegen der Lagerung der Haken auf ortsfesten Zapfen ein sattes Anliegen derselben bei schrägverlaufenden Taschen nicht gewährleistet. Der gleiche Nachteil ist auch bei einer anderen bekannten Plattenspannvorrichtung vorhanden, bei welcher die in ortsfesten zylindrischen Bohrungen drehbar gelagerten Spannhaken von einseitig federnd anliegenden Kipphebeln oder damit verschraubten Blattfederbündeln betätigbar sind, auf die ihrerseits eine Nockenwelle einwirkt.Although it is already known, the clamping hooks of stereotype plate clamping devices to be resiliently supported against their actuating element. In addition to the considerable effort by using toggle-like acting handlebars, which by an elastic pressure element are coupled, is in this version because of the storage of the hook on stationary The pin does not guarantee a snug fit of the same in the case of inclined pockets. The same disadvantage is also found in another known plate clamping device present, in which the rotatably mounted in stationary cylindrical bores Tension hooks of rocker arms that are spring-loaded on one side or screwed to them Leaf spring bundles can be actuated, on which a camshaft acts in turn.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigt F i g. 1 einen Teilschnitt mit Spannhaken und Gegenhaken durch einen Plattenzylinder, F i g. 2 einen Schnitt nach Linie 11-II der F i g. 1. Die Platten 2 werden mittels längs der beiden geraden Kanten in Ausnehmungen 5 eingreifender Spannhaken 3 bzw. federnder Gegenhaken 4 auf dem Plattenzylinder 1 durch Verdrehen der Nockenwelle 6 unter Zusammendrücken der Feder 7 festgespannt. Wenn aus fertigungstechnischen Gründen die Nuten 5 nicht alle in einer Linie fluchten, sondern, wie bei 5' angedeutet ist, verschiedenen Abstand von der Plattenkante aufweisen, wird, wie ohne weiteres aus der Zeichnung hervorgeht, nur ein Teil der über die Plattenbreite reichenden Haken zum Tragen kommen. Die beim Lauf der Maschine auftretenden erheblichen Zentrifugalkräfte werden daher nur von wenigen Haken aufgenommen, wodurch die Gefahr des Ablösens der Platte und damit schwerer Beschädigungen besteht. Um hier einen Ausgleich zu schaffen, d. h. zu erreichen, daß alle Haken in den zugehörigen Nuten voll zum Anliegen kommen, sind zwischen der Nockenwelle 6 und den von ihr betätigten Haken 3, 3' an diesen federnd abgestützte, im Plattenzylinder 1 schwenkbar gelagerte Druckstücke 3" angeordnet. Die federnde Abstützung der Haken 3, 3' gegen die Druckstücke erfolgt vorzugsweise durch eine Tellerfeder od. dgl., welche beim Weiterdrehen der Spannspindel 6 bei einem bereits anliegenden Haken zusammengedrückt wird und so das Eindringen eines benachbarten Hakens in eine tiefere Nut ermöglicht. Um bei nicht genau achsparallelem Verlauf der Nuten ein Anliegen der Haken 3' über die ganze Breite zu gewährleisten, sind dieselben in den Druckstücken 3" an ihrem Fuß um -ihre parallel zur Zylindermittelachse verlaufende Querachse schwenkbar, z. B. in einer Kugelpfanne 21 gelagert, wie aus F i g. 2 hervorgeht. Die Hakenteile 3" sind im übrigen am einen Ende mit einem zylindrischen Kopf 8 versehen, der als Schwenkachse dient.An exemplary embodiment of the subject matter of the invention is shown in the drawing. It shows F i g. 1 shows a partial section with clamping hooks and counter hooks through a plate cylinder, FIG. 2 shows a section along line 11-II of FIG. 1. The plates 2 are clamped tightly on the plate cylinder 1 by turning the camshaft 6 while compressing the spring 7 by means of clamping hooks 3 or resilient counter hooks 4 engaging in recesses 5 along the two straight edges. If, for manufacturing reasons, the grooves 5 are not all aligned in a line, but, as indicated at 5 ', have different distances from the plate edge, only some of the hooks that extend across the plate width will be used, as is readily apparent from the drawing Wear come. The considerable centrifugal forces that occur when the machine is running are therefore only absorbed by a few hooks, which means that there is a risk of the plate coming off and causing severe damage. In order to compensate for this, ie to ensure that all the hooks come fully into contact in the associated grooves, there are pressure pieces 3, which are resiliently supported on the camshaft 6 and the hooks 3, 3 'actuated by it and pivotably mounted in the plate cylinder 1 The resilient support of the hooks 3, 3 'against the pressure pieces is preferably provided by a plate spring or the like, which is compressed when the clamping spindle 6 is turned further with a hook that is already in contact and thus enables an adjacent hook to penetrate a deeper groove In order to ensure that the hooks 3 'are in contact over the entire width if the grooves are not exactly axially parallel, they can be pivoted in the pressure pieces 3 "at their foot about their transverse axis running parallel to the cylinder center axis, e.g. B. stored in a ball socket 21 , as shown in FIG. 2 shows. The hook parts 3 ″ are also provided at one end with a cylindrical head 8 which serves as a pivot axis.
