Description

Die Erfindung betrifft einen Plattenzylinder für eine Rotations-Offsetdruckmaschine, an den ein Gummizylinder anstellbar ist, mit einer Vorrichtung zum zonenweisen Abtasten der Platteneinfärbung gemäss Oberbegriff des Anspruchs 1.The invention relates to a plate cylinder for a rotary offset printing machine, to which a blanket cylinder can be adjusted, with a device for zone-wise scanning of the plate ink according to the preamble of claim 1.

Aus der DE-A- 20 11 979 ist ein Plattenzylinder der vorangehend spezifizierten Art bekannt. Nachteilig bei einer solchen Messung der Farbdichte in den einzelnen Farbzonen ist es, dass diese infolge ihrer Berührung mit dem Gummizylinder im Laufe der Zeit verschmutzt werden, da von Druckträgern Papierstaub über den Gummizylinder auf den Plattenzylinder übertragen wird, wodurch es zu Messfehlern kommen kann.From DE-A-20 11 979 a plate cylinder of the type specified above is known. The disadvantage of such a measurement of the color density in the individual ink zones is that they become soiled over time due to their contact with the rubber cylinder, since paper dust is transferred from the printing medium to the plate cylinder via the rubber cylinder, which can lead to measurement errors.

Aufgabe der Erfindung ist es, eine Messung der Farbdichte auf der aufgespannten Platte am Plattenzylinder zu ermöglichen, ohne dass eine Verschmutzung der Messfelder während des Fortdruckes zu befürchten ist. Diese Aufgabe wird duch die Anwendung der Merkmale des Patentanspruchs 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen:

  • Fig. 1 eine schematische Darstellung der Grubenbereiche eines Plattenzylinders und eines Gummizylinders und
  • Fig. 2 eine Farbmessvorrichtung an dem Plattenzylinder.
  • Fig. 1 zeigt schematisch jeweils den die Grube umfassenden Teil eines Plattenzylinders 1 und eines Gummizylinders 2. Auf dem Plattenzylinder 1 ist in üblicher Weise eine Platte 3 aufgespannt, während der Gummizylinder 2 ein Gummituch 4 trägt. Mit Hilfe einer Spannspindel 5 sind die Enden der Platte 3 und mit Hilfe der Spannspindeln 6 und 7 die Enden des Gummituches 4 fixierbar. Üblicherweise wird unter der Platte 3 eine Unterlage 8 und unter dem Gummituch 4 eine Unterlage 9 verwendet.
The object of the invention is to enable a measurement of the color density on the clamped plate on the plate cylinder without fear of contamination of the measuring fields during the production run. This object is achieved by the application of the features of claim 1. Further developments of the invention result from the subclaims and from the description in conjunction with the drawings. In these show:
  • Fig. 1 is a schematic representation of the pit areas of a plate cylinder and a blanket cylinder and
  • Fig. 2 shows a color measuring device on the plate cylinder.
  • Fig. 1 shows schematically the part of the pit comprising a plate cylinder 1 and a rubber cylinder 2. A plate 3 is clamped on the plate cylinder 1 in a conventional manner, while the rubber cylinder 2 carries a rubber blanket 4. With the help of a clamping spindle 5, the ends of the plate 3 and with the help of the clamping spindles 6 and 7, the ends of the rubber blanket 4 can be fixed. A base 8 is usually used under the plate 3 and a base 9 under the rubber blanket 4.

Wie Fig. 1 erkennen lässt, ist die Breite des Kanals 10 des Plattenzylinders 1 in Umfangsrichtung gesehen schmäler als die Grube 11 des Gummizylinders. Durch Übereinanderstellen der Druckendepositionen beider Zylinder 1, 2 erhält der Druckanfang des Plattenzylinders 1 einen Vorlauf gegenüber jenem des Gummizylinders 2. Dadurch weist die Platte 3 eine Zone bzw. einen Bereich A auf, der zwar eingefärbt wird, aber mit dem Gummituch 4 nicht in Berührung kommt und somit dorthin keine Farbe abgeben kann. Wie eingangs bereits erwähnt, bringt dies u.a. den wesentlichen Vorteil, dass eine Verschmutzung des Bereiches A vom Druckträger her über das Gummituch 4 nicht zu befürchten ist.As can be seen in FIG. 1, the width of the channel 10 of the plate cylinder 1 is narrower in the circumferential direction than the pit 11 of the rubber cylinder. By superimposing the printing end positions of both cylinders 1, 2, the start of printing of the plate cylinder 1 receives a lead over that of the blanket cylinder 2. As a result, the plate 3 has a zone or area A, which is colored, but does not come into contact with the blanket 4 comes and therefore can not give color there. As already mentioned at the beginning, this brings among other things the significant advantage that contamination of area A from the printing substrate is not to be feared via the rubber blanket 4.

Erfindungsgemäss wird für jede Farbzone Z in diesem Bereich A bei der Herstellung der Platte 3 eine Kontrolleiste bzw. ein Messfeld 12 (Fig.2) erzeugt, d.h. aufkopiert. Bekanntlich steht der Plattenzylinder 1 in ständiger Berührung mit mindestens einer Farbauftragswalze oder einem Farbzylinder (nicht gezeigt), der die Platte 3 kontinuierlich einfärbt.According to the invention, a control strip or a measuring field 12 (FIG. 2) is generated for each color zone Z in this area A during the manufacture of the plate 3, i.e. copied on. As is known, the plate cylinder 1 is in constant contact with at least one inking roller or an ink cylinder (not shown), which continuously colors the plate 3.

Bei der erfindungsgemässen Anordnung der Messfelder 12 in dem Bereich A erfolgt somit auch eine stetige Einfärbung dieser Messfelder 12 bei der Rotation des Plattenzylinders 1. Nachdem dieser Bereich A nicht in Berührung mit dem Gummituch 4 auf dem Gummizylinder 2 kommt, wird auch keine Farbe von den Messfeldern 12 auf das Gummituch 4 übertragen. Es entsteht lediglich nach einer betimmten Anlaufperiode duch Rückspaltung eine Übertragung von Farbe von dem Bereich A bzw. von den Messfeldern 12 zur Farbauftragwalze und eine erneute Einfärbung derselben durch die Farbauftragwalze bis sich ein Gleichgewichtszustand eingestellt hat. Auf den Messfeldern 12 in dem Bereich A entsteht somit eine Einfärbung, die ein Mass für die Einfärbung des Bedruckstoffes in der jeweiligen Zone Z ist.With the arrangement of the measuring fields 12 according to the invention in the area A, there is therefore also a constant coloring of these measuring fields 12 during the rotation of the plate cylinder 1. After this area A does not come into contact with the rubber blanket 4 on the rubber cylinder 2, no color becomes from the Transfer measuring fields 12 to the rubber blanket 4. Only after a certain start-up period, by means of cleavage, a transfer of color from the area A or from the measuring fields 12 to the inking roller and a re-inking of the same by the inking roller occurs until an equilibrium has been reached. A coloration, which is a measure of the coloration of the printing material in the respective zone Z, thus arises on the measuring fields 12 in the area A.

Die erfindungsgemäss ausgebildete Kontrollleiste in Form von den einzelnen Farbzonen Z zugeordneten Messfeldern 12 wird während des Maschinenbetriebes von einem Densitometer 13 stufenweise, d.h. nacheinander, abgetastet. Das Densitometer umfasst eine Strahlungsquelle 14 und einen Sensor 15 und ist auf einer als Transportspindel dienenden Gewindespindel 16 angeordnet.The control bar designed in accordance with the invention in the form of measuring fields 12 assigned to the individual color zones Z is stepped by a densitometer 13 during machine operation, i.e. sequentially, sampled. The densitometer comprises a radiation source 14 and a sensor 15 and is arranged on a threaded spindle 16 serving as a transport spindle.

Letztere kann durch einen Elektromotor, vorzugsweise durch einen Schrittschaltmotor um ein definiertes Mass gedreht werden, so dass der Messkopf 13 schrittweise von Farbzone zu Farbzone, d.h. von einem Messfeld 12 zum nachfolgenden Messfeld bewegt werden. Beim Vorbeilaufen des Messfeldes 12 an dem Messkopf 13 erfolgt dessen Abtastung zwecks Ermittlung der Einfärbung, d. h. der in der jeweiligen Zone Z vorhandenen Farbdichte. Wird beispielsweise das Messfeld 12 in der ersten Farbzone Z abgetastet, so kann während der nachfolgenden Drehung des Plattenzylinders 1 der Messkopf 12 durch Aktivierung des Elektromotors 17 um einen Schritt nach rechts, d. h. zur zweiten Farbzone bewegt werden, so dass während der darauffolgenden Drehung des Plattenzylinders 1 das in der zweiten Farbzone Z befindliche Messfeld 12 abgetastet werdem kann.The latter can be rotated by a defined amount by an electric motor, preferably by a stepping motor, so that the measuring head 13 is gradually moved from ink zone to ink zone, i.e. be moved from a measuring field 12 to the subsequent measuring field. When the measuring field 12 runs past the measuring head 13, it is scanned in order to determine the coloration, i. H. the color density present in the respective zone Z If, for example, the measuring field 12 is scanned in the first color zone Z, the measuring head 12 can be turned one step to the right, that is to say by activating the electric motor 17, during the subsequent rotation of the plate cylinder 1. H. are moved to the second color zone, so that during the subsequent rotation of the plate cylinder 1 the measuring field 12 located in the second color zone Z can be scanned.

Fig. 2 zeigt in schematischer Darstellung die Anordnung des Plattenzylinders 1 und des Gummizylinders 2 zwischen zwei Seitenwänden 18 üblicherweise, in denen auch die Gewindespindel 16 gelagert und der Elektromotor 17 angeflanscht sein kann.Fig. 2 shows a schematic representation of the arrangement of the plate cylinder 1 and the rubber cylinder 2 between two side walls 18, in which the threaded spindle 16 is also mounted and the electric motor 17 can be flanged.

Die in dem Messkopf 13 ermittelten Werte gelangen über eine Leitung 19 in einen Rechner 20, der über eine Leitung 21 zeitgerecht den Elektromotor 17 ansteuert, um den Messkopf 13 in der beschriebenen Weise von links nach rechts oder umgekehrt schrittweise weiterzubewegen.The values determined in the measuring head 13 reach a computer 20 via a line 19, which controls the electric motor 17 in a timely manner via a line 21 in order to move the measuring head 13 step by step in the manner described from left to right or vice versa.

In Abhängigkeit von den ermittelten, die Einfärbung repräsentierenden Werten steuert der Rechner 20 über eine Leitung 22 Farbzonenstellelemente 23 beispielsweise in Form von motorisch betätigbaren Farbzonenstellschrauben. Dadurch wird der Abstand eines Farbmessers 24 in der jeweiligen Farbzone Z entsprechend verändert und die von dem Farbkasten 25 mit Farbkastenwalze 26 abgegebene Farbe quantitativ entsprechend der erforderlichen Farbgebung nachgeregelt.Depending on the determined values representing the coloring, the computer 20 controls color zone adjusting elements 23 via a line 22, for example in the form of motorized ink zone adjusting screws. As a result, the distance between an ink knife 24 in the respective ink zone Z is changed accordingly and that of the ink fountain 25 with ink fountain roller 26 color adjusted quantitatively according to the required coloring.

Wird beispielsweise im Messkopf 13 in einer bestimmten Farbzone Z eine zu intensive Einfärbung festgestellt, so sorgt der Rechner 20 dafür, dass das entsprechende Farbzonenstellelement 23 das Farbmesser 24 in dieser Zone näher an die Farbkastenwalze 26 heranfährt, wodurch die Farbabgabe reduziert und dadurch die gewünschte Einfärbung in dieser Zone erreicht wird.

If, for example, too intensive a coloration is determined in the measuring head 13 in a certain ink zone Z, the computer 20 ensures that the corresponding ink zone adjusting element 23 moves the ink knife 24 closer to the ink fountain roller 26 in this zone, thereby reducing the ink output and thereby the desired inking is achieved in this zone.
