Definitions

  • the perforation bar 9 is approximately rectangular in cross section, the row of pins 10 being in the form of tips 11 of the perforation bar 9.
  • the arrangement of the perforating bar 9 directly behind the gripper pad 7 ensures that a sheet 8 guided between the grippers 6 and the gripper pad 7 on its front edge is impaled or needled by the prongs or pins 11 of the perforating bar 9, since the Impression cylinder 2 employed blanket cylinder 1 after contacting the pits receives contact with the sheet 8 to be printed.
  • the sheet 8 guided in the grippers 6 is pressed shortly before reaching the pressure line against the tips or pins 11 of the perforating strip 9 through the rubber blanket 4, whereby the tips 11 penetrate into the area of the front edge of the sheet 8, so that the latter is needled.
  • the gripper function in particular the gripper closing function, is significantly improved.
  • the perforating strip 9 should be somewhat recessed in the impression cylinder 2, as can be seen in FIG. 1, so that only the tips 11 protrude beyond its outer surface. Since the tips 11 in front of the print line, i.e. H. in the pressure-free area of the front edge of the sheet 8, penetrate into it, there is no damage to the printed image itself. As is known, this pressure-free strip is usually removed, ie. H. cut off.

Description

Die Erfindung betrifft einen Gegendruckzylinder für eine Bogen-Offsetrotationsdruckmaschine mit Greifern zum aufnadelnden Erfassen von Bogen, die zum Aufbringen eines Druckes an einem, mit einem Gummituch bespannten Zylinder vorbeiführbar sind (DE-B-1 236 527).The invention relates to a counter-pressure cylinder for a sheet-fed offset rotary printing machine with grippers for needling detection of sheets which can be guided past a cylinder covered with a rubber blanket for applying pressure (DE-B-1 236 527).

Es ist bekannt, daß in Bogen-Offsetrotationsdruckmaschinen, insbesondere bei solchen, die nach dem 5-Zylinder-System konzipiert sind, bei denen bekanntlich zwei Gummizylinder mit einem Gegendruckzylinder zusammenarbeiten, ein erheblicher Zug an den Bogen entsteht, während diese an den Gummizylindern vorbeigeführt werden. Diese Zugkräfte versuchen, den Bogen aus den Greifern zu ziehen. Es wurde erkannt, daß diese Kräfte ein Verziehen der Bogenvorderkante zwischen den Greifern verursachen, was zu einem Doublieren nach hinten hinaus führen kann. Auch bei relativ hohen Greiferschließkräften und einer Aufrauhung der Greifer und/oder Greiferauflage kommt es häufig vor, daß ein Doublieren auftritt, dessen Ursache eine Bewegung des Bogens in den Greifern Infolge der erwähnten Zugkräfte ist. Häufig ist dieses Schlupfen der Bogen in den Greifern über die Breite der Maschine ungleichmäßig, d. h. der Bogen schlupft in den Randbereichen nicht in dem Maß wie im mittleren Bereich. Aus der DE-PS 155 403 sind bereits Greifer bekannt, bei denen zur Unterstützung der Haltekraft im Greifer jeweils ein Stift angeordnet ist, der beim Schließen der Greifer den zu erfassenden Bogen durchlöchert. Nachteilig bei solchen Greifersystemen ist es, daß die durch die Stifte erzielbare, zusätzliche Fixierung der Bogen in den Greifern nur punktuell zur Wirkung kommt, da bekanntlich die Greifer voneinander beabstandet sind und daß die Greifer nicht mehr sicher schließen.It is known that in sheet-fed offset printing presses, in particular in those which are designed according to the 5-cylinder system, in which, as is known, two blanket cylinders work together with an impression cylinder, there is a considerable pull on the sheet while it is being guided past the blanket cylinders . These tensile forces try to pull the bow out of the grippers. It was recognized that these forces cause the leading edge of the sheet to warp between the grippers, which can result in doubling backwards. Even with relatively high gripper closing forces and a roughening of the grippers and / or gripper support, it often happens that doubling occurs, the cause of which is a movement of the sheet in the grippers as a result of the tensile forces mentioned. Often this slippage of the sheets in the grippers is uneven across the width of the machine, i. H. the bow slips in the edge areas not to the same extent as in the middle area. From DE-PS 155 403 grippers are already known in which a pin is arranged to support the holding force in the gripper, which pierces the sheet to be detected when the gripper closes. A disadvantage of such gripper systems is that the additional fixation of the sheets in the grippers that can be achieved by the pins only has a selective effect, since it is known that the grippers are spaced apart and that the grippers no longer close securely.

Aufgabe der Erfindung ist es, einen Gegendruckzylinder der eingangs bezeichneten Art in der Weise mit zusätzlichen, die Bogenhaltekraft erhöhenden Elementen auszustatten, daß gewünschtenfalls über die gesamte Bogenbreite kontinuierlich eine zusätzliche Haltekraft für den in und/oder zwischen den Greifern geführten Bogen geboten und/oder daß die Greiferschließfunktion verbessert wird. Diese Aufgabe wird durch die Anwendung der Merkmale des Patentanspruchs 1 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen

  • Fig. 1 in schematischer Darstellung einen Teil der Grubenbereiche eines Gummizylinders und eines Gegendruckzylinders,
  • Fig. 2 und 3 eine in Fig. 1 verwendete, vergrößert dargestellte Perforierleiste und
  • Fig. 4 bis 8 Ausführungsbeispiele der Erfindung.
The object of the invention is to equip a counter-pressure cylinder of the type described at the outset with additional elements which increase the sheet holding force in such a way that, if desired, an additional holding force is continuously provided over the entire sheet width for the sheet guided in and / or between the grippers and / or that the gripper closing function is improved. This object is achieved by using the features of patent claim 1. Further developments result from the subclaims and from the description in conjunction with the drawings. Show in these
  • 1 is a schematic representation of part of the pit areas of a blanket cylinder and an impression cylinder,
  • 2 and 3 used in Fig. 1, enlarged perforation bar and
  • 4 to 8 embodiments of the invention.

Fig. 1 zeigt teilweise die Grubenbereiche eines Gummizylinders 1 und eines Gegendruckzylinders 2. In dem Grubenbereich 3 ist in herkömmlicher Weise ein Ende eines Gummituches 4 fixiert, das auf einer Unterlage 5 angeordnet ist.1 partially shows the pit areas of a rubber cylinder 1 and an impression cylinder 2. In the pit area 3, one end of a rubber blanket 4, which is arranged on a base 5, is fixed in a conventional manner.

Mit Hilfe von Greifern 6 in der Grube des Gegendruckzylinders 2, die gegen eine Greiferauflage 7 schwenkbar sind, wird zum Aufbringen eines Druckes ein Bogen 8 zunächst mit seiner Vorderkante an dem Gummizylinder 1 vorbeigeführt, so daß anschließend auf der Oberseite des Bogens 8 von dem Gummituch 4 Farbe übertragen werden kann. Die Drehrichtung des Gegendruckzylinders 2 ist durch einen Pfeil « p » angedeutet.With the help of grippers 6 in the pit of the impression cylinder 2, which can be pivoted against a gripper pad 7, a sheet 8 is first passed with its front edge to the rubber cylinder 1 so that pressure is then applied to the top of the sheet 8 by the rubber blanket 4 color can be transferred. The direction of rotation of the impression cylinder 2 is indicated by an arrow «p».

Wie eingangs bereits erwähnt wurde, wirkt beim Bedrukken des Bogens 8 eine erhebliche Zugkraft auf diesen, die den Bogen aus den Greifern 6 herauszuziehen versucht. Erfindungsgemäß wird vorzugsweise unmittelbar - in Drehrichtung « p des Gegendruckzylinders 2 gesehen - hinter der Greiferauflage 7 eine Stiftreihe 10 vorzugsweise in Form einer in den Figuren 2 und 3 dargestellten Perforierleiste 9 vorgesehen. Die Perforierleiste 9 ist im Querschnitt etwa rechtwinklig ausgebildet, wobei die Stiftreihe 10 sich in Form von Spitzen 11 der Perforierleiste 9 ergibt.As already mentioned at the beginning, when the sheet 8 is printed, a considerable tensile force acts on it, which tries to pull the sheet out of the grippers 6. According to the invention, a row of pins 10, preferably in the form of a perforating bar 9 shown in FIGS. 2 and 3, is preferably provided directly — viewed in the direction of rotation “p of the impression cylinder 2 — behind the gripper support 7. The perforation bar 9 is approximately rectangular in cross section, the row of pins 10 being in the form of tips 11 of the perforation bar 9.

Durch die Anordnung der Perforierleiste 9 unmittelbar hinter der Greiferauflage 7 wird erreicht, daß ein zwischen den Greifern 6 und der Greiferauflage 7 an seiner Vorderkante geführter Bogen 8 durch die Zacken bzw. Stifte 11 der Perforierleiste 9 aufgespießt bzw. aufgenadelt wird, da der an den Gegendruckzylinder 2 angestellte Gummizylinder 1 nach dem Überlaufen der Gruben Kontakt mit dem zu bedruckenden Bogen 8 erhält. Vorzugsweise wird durch das Gummituch 4 der in den Greifern 6 geführte Bogen 8 kurz vor dem Erreichen der Drucklinie gegen die Spitzen bzw. Stifte 11 der Perforierleiste 9 gedrückt, wodurch die Spitzen 11 im Bereich der Vorderkante des Bogens 8 in diesen eindringen, so daß dieser aufgenadelt wird. Gleichzeitig wird die Greiferfunktion, insbesondere die Greiferschließfunktion, wesentlich verbessert.The arrangement of the perforating bar 9 directly behind the gripper pad 7 ensures that a sheet 8 guided between the grippers 6 and the gripper pad 7 on its front edge is impaled or needled by the prongs or pins 11 of the perforating bar 9, since the Impression cylinder 2 employed blanket cylinder 1 after contacting the pits receives contact with the sheet 8 to be printed. Preferably, the sheet 8 guided in the grippers 6 is pressed shortly before reaching the pressure line against the tips or pins 11 of the perforating strip 9 through the rubber blanket 4, whereby the tips 11 penetrate into the area of the front edge of the sheet 8, so that the latter is needled. At the same time, the gripper function, in particular the gripper closing function, is significantly improved.

Die Perforierleiste 9 sollte etwas im Gegendruckzylinder 2 versenkt sein, wie aus Fig. 1 hervorgeht, so daß lediglich die Spitzen 11 über dessen Mantelfläche herausragen. Da die Spitzen 11 vor der Drucklinie, d. h. im druckfreien Bereich der Vorderkante des Bogens 8, in diesen eindringen, erfolgt keine Beschädigung des Druckbildes selbst. Bekanntlich wird dieser druckfreie Streifen üblicherweise entfernt, d. h. abgeschnitten.The perforating strip 9 should be somewhat recessed in the impression cylinder 2, as can be seen in FIG. 1, so that only the tips 11 protrude beyond its outer surface. Since the tips 11 in front of the print line, i.e. H. in the pressure-free area of the front edge of the sheet 8, penetrate into it, there is no damage to the printed image itself. As is known, this pressure-free strip is usually removed, ie. H. cut off.

In vorteilhafter Weise kann die in den Figuren 2 und 3 dargestellte Perforierleiste 9 gegebenenfalls über die gesamte Breite der Maschine angeordnet werden, um eine maximale zusätzliche Haltekraft für die Bogen 8 zu erreichen. Es ist häufig jedoch auch ausreichend, lediglich über einen Teilbereich, z. B. zwischen den Greifern, Perforierleisten anzuordnen. Diese können beispielsweise in die in Fig. 1 angedeuteten Vertiefungen an der Oberfläche des Gegendruckzylinders 2 eingeklebt oder eingeschraubt werden.Advantageously, the perforating bar 9 shown in FIGS. 2 and 3 can optionally be arranged over the entire width of the machine in order to achieve a maximum additional holding force for the sheets 8. However, it is often also sufficient to use only a partial area, e.g. B. between the grippers to arrange perforating strips. These can, for example, be glued or screwed into the depressions indicated in FIG. 1 on the surface of the impression cylinder 2.

Im Vergleich zu den bekannten, mit Stiften ausgestatteten Greifern bietet die erfindungsgemäße Vorrichtung den Vorteil, daß die Perforierleisten 9 an beliebigen Stellen, unabhängig von den Greiferpositionen, angeordnet werden können, so daß eine ausreichende und gleichmäßige, zusätzliche Haltekraft für den Bogentransport gewährleistet wird. Es versteht sich, daß anstelle der Perforierleiste 9 gemäß Fig. 2 und 3 auch andere Stiftreihen, beispielsweise aus einzelnen Stiften oder Nadeln, unter Anwendung des der Erfindung zugrundeliegenden Prinzips eingesetzt werden können.Compared to the known grippers equipped with pins, the device according to the invention has the advantage that the perforating strips 9 can be arranged at any point, regardless of the gripper positions, so that a sufficient and uniform, additional holding force for the sheet transport is ensured. It goes without saying that instead of the perforating strip 9 according to FIGS. 2 and 3, other rows of pins, for example made of individual pins or needles, can also be used using the principle on which the invention is based.

Fig. 4 zeigt eine Abwandlung der Perforierleiste von Fig. 2 und 3. Hier sind die Spitzen der Perforierleiste 12 als Schneiden etwa trapezförmig ausgebildet.FIG. 4 shows a modification of the perforating strip from FIGS. 2 and 3. Here the tips of the perforating strip 12 are designed as cutting edges in an approximately trapezoidal shape.

Fig. 5 läßt im Vergleich mit Fig. 1 erkennen, daß der Gummizylinder 1 so bezogen auf den Gegendruckzylinder 2 verdreht ist, daß die Druckanfangslinie in Richtung Grube 3 verschoben wird, wodurch eine verbesserte Schließung der Greifer 6 erreicht wird, unter denen die Perforierleiste 9 angeordnet ist, so daß das Gummituch 4 den Greifer 6 zudrückt und dadurch gleichzeitig den Bogen 8 aufspießt.Fig. 5 shows in comparison with Fig. 1 that the rubber cylinder 1 is rotated relative to the impression cylinder 2 so that the pressure start line is shifted towards the pit 3, whereby an improved closure of the gripper 6 is achieved, under which the perforating bar 9th is arranged so that the rubber blanket 4 presses the gripper 6 and thereby impaling the sheet 8 at the same time.

Fig. 6 zeigt eine Variante, bei der in der Grube 3 ein mit einem Schaumstoff (14) oder elastischen Material gepolsterter Druckblock 13 angeordnet ist, der den Greifer 6 zudrückt und dadurch kraftvoll den Bogen 8 aufnadelt.FIG. 6 shows a variant in which a pressure block 13 padded with a foam (14) or elastic material is arranged in the pit 3, which presses the gripper 6 and thereby forcefully needles the sheet 8.

Eine weitere vorteilhafte Weiterbildung der Erfindung ergibt sich aus Fig. 7. Dort ist eine Nadel 15 aus einer Nadelreihe (nicht sichtbar) einstellbar, die durch einen Exzenter 17 gegen den Druck einer Feder 16 jeweils verstellbar ist. Dadurch können die aus der kreiszylindrischen Mantelkontur herausragenden Nadelspitzen in Abhängigkeit der Bogen- bzw. Exemplardicke voreingestellt werden.A further advantageous development of the invention results from FIG. 7. There, a needle 15 can be adjusted from a row of needles (not visible), which can be adjusted by an eccentric 17 against the pressure of a spring 16. As a result, the needle tips protruding from the circular cylindrical jacket contour can be preset depending on the sheet or specimen thickness.

Anstelle der in Fig. 7 verwendeten Nadeln 15 können wiederum gemäß Fig. 8 auch auf einem Stempel 18 angeordnete Perforierstrips eingesetzt werden. Gegen den Druck einer Feder 19 ist der Stempel 18 höhenverstellbar und rückstellbar, so daß keine Markierung bzw. Aufnadelung stattfindet, indem ein Exzenter 20 über einen Hebel 21 verdreht wird.Instead of the needles 15 used in FIG. 7, perforating strips arranged on a stamp 18 can again be used according to FIG. 8. Against the pressure of a spring 19, the stamp 18 is height-adjustable and resettable, so that no marking or needling takes place by rotating an eccentric 20 via a lever 21.

Entsprechend der verwendeten Maschinen- bzw. Zylinderkonfiguration kann der Zylinder 2 auch als Gummi- oder Plattenzylinder mit Greifern ausgebildet sein.Depending on the machine or cylinder configuration used, the cylinder 2 can also be designed as a rubber or plate cylinder with grippers.
