Description
Die Erfindung betrifft einen Formzylinder einer Rollenrotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a forme cylinder of a web-fed rotary printing press according to the preamble of patent claim 1.
Rollendruckmaschinen, insbesondere Zeitungsdruckmaschinen, verfügen über mehrere Druckeinheiten, wobei jede Druckeinheit unter anderem mindestens einen Formzylinder und mindestens einen Übertragungszylinder aufweist. Auf den Formzylindern werden Druckplatten und auf den Übertragungszylindern werden Gummitücher befestigt, weshalb die Formzylinder auch als Druckplattenzylinder und die Übertragungszylinder auch als Gummituchzylinder bezeichnet werden. Mit jedem Formzylinder wirkt ein Übertragungszylinder derart zusammen, dass beim Drucken ein Formzylinder auf dem jeweiligen Übertragungszylinder abrollt. Beim Drucken besteht demnach ein Rollkontakt zwischen den Formzylindern und den Übertragungszylindern. Beim Drucken bzw. beim Abrollen der Formzylinder auf den jeweiligen Übertragungszylindern können sich Zylinderschwingungen ausbilden, welche die Druckqualität beeinträchtigen. Zylinderschwingungen müssen demnach zur Gewährleistung einer guten Druckqualität minimiert werden.Web-fed printing presses, in particular newspaper printing presses, have a plurality of printing units, wherein each printing unit has inter alia at least one forme cylinder and at least one transfer cylinder. The form cylinders are pressure plates and on the transfer cylinders rubber blankets are fixed, which is why the forme cylinder also referred to as printing plate cylinder and the transfer cylinder as a blanket cylinder. With each forme cylinder, a transfer cylinder cooperates in such a way that, during printing, a forme cylinder rolls on the respective transfer cylinder. When printing, therefore, there is a rolling contact between the forme cylinders and the transfer cylinders. When printing or when unrolling the forme cylinder on the respective transfer cylinders cylinder vibrations can form, which affect the print quality. Cylinder vibrations must therefore be minimized to ensure good print quality.

Wie bereits erwähnt, verfügt im Ausführungsbeispiel der
Nach einer ersten Alternative verfügt der Formzylinder 10 bzw. der Spannkanal 15 über eine axiale Länge, dass in Axialrichtung zwei Druckplatten nebeneinander positionierbar sind. Nach einer zweiten Alternative verfügt der Formzylinder 10 bzw. Spannkanal 15 über eine axiale Länge, dass in Axialrichtung drei Druckplatten nebeneinander positionierbar sind. Nach einer dritten Alternative weist der Formzylinder 10 bzw. Spannkanal 15 eine axiale Länge auf, dass in Axialrichtung vier oder auch sechs Druckplatten nebeneinander positionierbar sind. Weiterhin ist auch vorstellbar, dass am Formzylinder 10 in Axialrichtung fünf oder sieben oder acht Druckplatten nebeneinander positionierbar sind.According to a first alternative, the
Da im Ausführungsbeispiel der
Die Druckplatten können dabei eine oder mehrere stehende Druckseiten in Umfangsrichtung und/oder axialer Richtung und/oder eine oder mehrere liegende Druckseiten in Umfangsrichtung und/oder axialer Richtung aufweisen. Eine Druckplatte kann z.B. in Umfangsrichtung hintereinander zwei stehende Druckseiten aufweisen. Weiterhin kann eine Druckplatte auch z.B. in axialer Richtung vier liegende Druckseiten nebeneinander aufweisen. Auch ist es möglich, dass eine Druckplatte eine Kombination von stehenden und liegenden Seiten aufweist, die sowohl in axialer Richtung nebeneinander als auch in Umfangsrichtung hintereinander positioniert sind.The printing plates can have one or more stationary pressure sides in the circumferential direction and / or axial direction and / or one or more lying pressure sides in the circumferential direction and / or axial direction. A printing plate may e.g. have two standing pressure sides in the circumferential direction one behind the other. Furthermore, a printing plate may also be used e.g. have in the axial direction four lying pressure sides next to each other. It is also possible for a pressure plate to have a combination of upright and lying sides, which are positioned one after the other both in the axial direction next to one another and in the circumferential direction.
Im Unterschied zum Ausführungsbeispiel der
Weiterhin ist es vorstellbar, dass der Formzylinder über mehrere Spannkanäle verfügt, die sich in axialer Richtung lediglich abschnittsweise entlang des Formzylinders erstrecken. In diesem Fall kann nach einer ersten Alternative an jeder axialen Position des Formzylinders in Umfangsrichtung gesehen jeweils nur ein Spannkanal vorhanden sein, wobei dann mindestens ein Spannkanal gegenüber den anderen Spannkanälen in Umfangsrichtung versetzt ist. Nach einer zweiten Alternative können an jeder axialen Position des Formzylinders in Umfangsrichtung gesehen zwei Spannkanäle vorhanden sein, wobei dann mindestens zwei, an derselben axialen Position verlaufende Spannkanäle des Formzylinders gegenüber den anderen Spannkanälen desselben in Umfangsrichtung versetzt sind. Nach einer weiteren Alternative kann jeder axialen Position des Formzylinders in Umfangsrichtung gesehen eine Gruppe von mindestens zwei, vorzugsweise zwei oder vier, Spannkanälen, vorhanden sein, wobei mindestens eine Gruppe von an derselben axialen Position verlaufenden Spannkanälen gegenüber den anderen Spannkanälen der oder jeden anderen Gruppe in Umfangsrichtung versetzt ist. Durch die in Umfangsrichtung versetzte Ausgestaltung der Spannkanäle an den Formzylindern können Zylinderschwingungen abermals minimiert werden. In jedem Fall ist jedoch die wirksame Spannkanalbreite aller Spannkanäle kleiner als 7 mm, wobei die wirksame Spannkanalbreite zwischen 3 mm und 7 mm, vorzugsweise zwischen 4 mm und 5mm oder alternativ zwischen 6 mm und 7 mm liegt.Furthermore, it is conceivable that the forme cylinder has a plurality of clamping channels, which in the axial direction only partially along the forme cylinder extend. In this case, according to a first alternative, viewed in the circumferential direction, only one clamping channel can be present at each axial position of the forme cylinder, in which case at least one clamping channel is offset relative to the other clamping channels in the circumferential direction. According to a second alternative, two clamping channels may be present at each axial position of the forme cylinder in the circumferential direction, in which case at least two clamping channels of the forme cylinder running at the same axial position are circumferentially offset from the other clamping channels. According to a further alternative, a group of at least two, preferably two or four, clamping channels, seen in the circumferential direction of each axial position of the forme cylinder, be present, wherein at least one group of running at the same axial position clamping channels with respect to the other clamping channels of the or any other group in Circumferential direction is offset. Due to the offset in the circumferential direction configuration of the clamping channels on the cylinders form cylinder oscillations can be minimized again. In any case, however, the effective chuck channel width of all chuck channels is less than 7 mm, the effective chuck channel width being between 3 mm and 7 mm, preferably between 4 mm and 5 mm, or alternatively between 6 mm and 7 mm.
Unter Bezugnahme auf
Nach dem Grundgedanken der hier vorliegenden Erfindung wird zur Minimierung von die Druckqualität beeinträchtigenden Zylinderschwingungen die Spannkanalbreite an Formzylindern auf eine wirksame Spannkanalbreite von maximal 7 mm begrenzt. Dies gilt sowohl dann, wenn der Formzylinder lediglich einen oder auch mehrere Spannkanäle aufweist. Verfügt der Formzylinder über mehrere Spannkanäle, die sich nicht über die gesamte axiale Breite des Formzylinders. sondern lediglich abschnittsweise entlang des Formzylinders erstrecken, so können die Spannkanäle zusätzlich in Umfangsrichtung zueinander versetzt sein, wodurch Zylinderschwingungen beim Drucken nochmals minimiert werden können.In accordance with the basic concept of the present invention, the clamping channel width of forming cylinders is limited to an effective clamping channel width of maximum 7 mm in order to minimize cylinder vibrations impairing the printing quality. This applies both when the form cylinder has only one or more clamping channels. The forme cylinder has several clamping channels, which does not extend over the entire axial width of the forme cylinder. but only partially extend along the forme cylinder, the clamping channels can be additionally offset in the circumferential direction to each other, whereby cylinder vibrations during printing can be minimized again.
