Abstract

A clamping gripper for sheet-fed rotary printing presses wherein tensions produced in the paper by adhesion forces of the blanket do not react in run-on shifts of the center of a main gripper member mounted for rotation with a fit clearance on the gripper shaft. A spring is so disposed, and the bearing plane and the gripper support surface are so inclined relative to one another, that the resultant force due to the spring force, thrust and bearing load intersect the gripper finger at the transfer point.

Description

Die Erfindung betrifft einen Klemmgreifer für Bogenrota­tionsdruckmaschinen nach dem Oberbegriff des Patentanspru­ches.The invention relates to a clamping gripper for sheet-fed rotary printing machines according to the preamble of the claim.

Bei einem aus der DE-PS 1 174 804 bekannten Klemmgreifer genannter Spezifikation ist der Greifergrundkörper halb­schalenförmig ausgearbeitet und dessen eines Ende mit dem am Klemmstück befindlichen Federfußpunkt verbunden. Das andere Ende stützt sich bei geschlossenem Greifer auf der Greiferauflage und bei offenem Greifer auf dem Stützan­schlag ab.In a specification known from DE-PS 1 174 804, the gripper base body is worked out in the form of a half-shell and one end thereof is connected to the spring base point located on the clamp piece. The other end is supported on the gripper support when the gripper is closed and on the support stop when the gripper is open.

Von Nachteil ist, daß die entstehenden Resultierenden glei­cher Richtung nicht durch den Übergabepunkt des Bogens an der Greiferspitze verlaufen. Dadurch bleibt ein derartiger Grei­fer empfindlich gegen unbeabsichtigte Richtungsänderungen der Auflagekraft, weil damit auch eine Richtungsänderung der Resultierenden und eine Verlagerung des dynamischen Auflage­punktes zwischen Greiferwelle und Lagerbohrung des drehenden Greifergrundkörpers eintritt. Der Greifer schiebt im Fortdruck durch Mittenverlagerungen des Passunsspiels. Ver­ursacht werden die unbeabsichtigten Richtungsänderungen der Auflagekraft z.B. durch wechselnde hohe Papierzugkräfte, die durch das Abreißen des Bogens im Abknickwinkel vom Gummituch des Gummituchzylinders entstehen.The disadvantage is that the resulting resultant in the same direction does not run through the transfer point of the arc at the gripper tip. As a result, such a gripper remains sensitive to unintentional changes in the direction of the bearing force, because this also results in a change in direction of the resultant and a shift in the dynamic contact point between the gripper shaft and the bearing bore of the rotating gripper body. The gripper pushes in the printing through shifting the center of the passport game. The unintentional changes in direction of the contact force are caused e.g. due to changing high paper tensile forces, which arise from the tearing of the sheet at a kink angle from the blanket of the blanket cylinder.

Bei einem aus der DE-OS 3 526 252 bekannten Greifer genannter Spezifikation ist zur Kompensation von Lagerkräften zusätz­lich eine zweite Feder vorgesehen. Auch dieser Greifer bleibt empfindlich gegen unbeabsichtigte Richtungsänderungen der Auflagekraft.In the case of a specification named from DE-OS 3 526 252, a second spring is additionally provided to compensate for bearing forces. This gripper also remains sensitive to unintentional changes in direction of the contact force.

Es sind auch Greiferkörper allgemein bekannt, die eine ge­schlossene Lagerbohrung aufweisen und auf der Greiferwelle zu einem Klemmstück abgefedert drehbar gelagert sind. Die Lagerpassung kann nicht sehr fein gewählt werden, da die Lagerstelle auf der Greiferwelle nicht geschmiert und nicht gegen Eindringen von Papierstaub und Puder geschützt werden kann. Begünstigt durch eine schnelle aber nur über kurze Wege erfolgende Bewegung des Greifergrundkörpers relativ zur Greiferwelle fressen sich die Greifer auf der Greifer­welle fest und verlieren damit ihre Federung. Da dies, sowie die damit verbundene Beschädigung der teuren Greifer­welle vermieden werden muß, wird oftmals ein großes Lager­spiel zugelassen. Dies macht aber wiederum eine passerhal­tige Bogenübergabe durch die Greifer unmöglich, weil der statische Auflagepunkt (bei geöffnetem Greifer) und der dynamische Auflagepunkt (bei geschlossenem Greifer) nicht übereinstimmen, so daß ständig Mittenverlagerungen des Passungsspiels eintreten. Ein derartiger Greifer ist z.B. in der US-PS 2 933 040 in Fig. 1 abgebildet.Gripper bodies are also generally known which have a closed bearing bore and on the gripper shaft are rotatably supported to form a sprag. The bearing fit cannot be selected very finely, since the bearing point on the gripper shaft cannot be lubricated and cannot be protected against the ingress of paper dust and powder. Favored by a fast but only short movement of the gripper body relative to the gripper shaft, the grippers seize themselves on the gripper shaft and thus lose their suspension. Since this and the associated damage to the expensive gripper shaft must be avoided, a large bearing clearance is often permitted. However, this in turn makes it impossible for the grippers to pass the sheet in register because the static support point (when the gripper is open) and the dynamic support point (when the gripper is closed) do not match, so that there is a constant shift in the center of play. Such a gripper is shown in FIG. 1, for example, in US Pat. No. 2,933,040.

Aufgabe der Erfindung ist es, einen Klemmgreifer zu schaf­fen, bei dem die entstehenden Resultierenden gleicher Richtung durch den Übergabepunkt an der Greiferspitze verlau­fen.The object of the invention is to provide a clamping gripper in which the resulting resultant run in the same direction through the transfer point at the gripper tip.

Gelöst wird diese Aufgabe gemäß den kennzeichnenden Merkma­len des Patentanspruches. Weiterbildungen ergeben sich in Verbindung mit der Zeichnung aus der Beschreibung.This object is achieved in accordance with the characterizing features of the patent claim. Further developments result in connection with the drawing from the description.

Der besondere Vorteil des erfindungsgemäßen Klemmgreifers besteht darin, daß der dynamische Auflagepunkt zwischen der Lagerbohrung des Greifergrundkörpers und der Greiferwelle im Fortdruck erhalten bleibt, unabhängig davon, welche Größe und Richtung die durch Adhäsionskräfte des Gummituches bewirkten Papierzugkräfte aufweisen. Außerdem weist der Klemmgreifer ein günstiges Schwingungsverhalten eines kurzen Greifers wegen des oberen Anlagepunktes auf, z.B. hohe Eigen­frequenz bei kleiner Amplitude. Beides ist besonders für schnellaufende Druckmaschinen von besonderer Bedeutung und war bisher nicht möglich.The particular advantage of the clamp gripper according to the invention is that the dynamic contact point between the bearing bore of the gripper base body and the gripper shaft is maintained in continuous printing, regardless of the size and direction of the paper tensile forces caused by the adhesive forces of the rubber blanket. In addition, the clamp gripper has a favorable vibration behavior of a short Gripper because of the upper contact point, eg high natural frequency with small amplitude. Both are particularly important for high-speed printing presses and were previously not possible.

Die Erfindung wird nachfolgend anhand einer Zeichnung in einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below with reference to a drawing in an exemplary embodiment.

Es zeigt:

  • Fig. 1 eine schematische Darstellung des im Abknickwinkel vom Gummituchzylinder wäh­rend des Fortdruckes abzureißenden Bogens,
  • Fig. 2 die Prinzipskizze eines Klemmgreifers mit den in geöffneter sowie in geschlossener Stellung auftretenden Kraftwirkungen an der Greiferspitze,
  • Fig. 3 ein Ausführungsbeispiel in Vorderansicht.
It shows:
  • 1 is a schematic representation of the sheet to be torn off at a bending angle from the blanket cylinder during production,
  • 2 shows the basic sketch of a clamping gripper with the force effects occurring in the open and in the closed position on the gripper tip,
  • Fig. 3 shows an embodiment in front view.

In Fig. 1 ist die bekannte Erscheinung schematisch darge­stellt, daß im Fortdruck ein Bogen 1 von einem mit einem Plattenzylinder 2 und einem Druckzylinder 3 zusammenwirken­den Gummituchzylinder 4 unter dem Abknickwinkel unter Papier­zugkräften 5 bzw. 5ʹ vom Gummituch 7 abgerissen werden muß, welche auf dem Klemmgreifer 6 an der Greiferspitze 15 in variabler Größe und Richtung einwirken. Mit 8 ist eine Ausle­getrommel in Fig. 1 bezeichnet. An einer Greiferwelle 9 ist ein Klemmstück 10 mittels Klemmschraube 11 befestigt. An dem Klemmstück 10 wird ein eine geschlossene Lagerbohrung aufwei­sender Greifergrundkörper 11 durch eine Feder 12 zur Anlage gebracht. Die Anordnung einer Stützebene 14 am Klemmstück 10, der Greiferspitze 15, der Lagerbohrung 13 des Greifergrund­körpers 11 und der Feder 12 ist so gewählt, daß die Wirkungs­ linien der Federkraft 18, der Abstützkraft 19 und der Aufla­gekraft 20 sich im Übergabepunkt 22 an der Greiferspitze 15 schneiden, d.h. sowohl wenn die Richtung der entstehenden Resultierenden 16 von der Federkraft 18 und der Abstützkraft 19 bestimmt wird, als auch im geschlossenen Zustand des Klemmgreifers 6, wenn die entstehende Resultierende 16ʹ durch die Federkraft 18 und die Auflagekraft 21 bestimmt wird. Alle Kräfte 5, 5ʹ, 16, 16ʹ, 18, 19, 20, 21 schneiden sich somit im Übergabepunkt 22 an der Greiferspitze 15.In Fig. 1 the known phenomenon is shown schematically that in production a sheet 1 of a blanket cylinder 2 and a printing cylinder 3 interacting with a blanket cylinder 4 at the bend angle under paper tensile forces 5 and 5 'of the blanket 7, which must be torn off on the clamp gripper 6 act on the gripper tip 15 in variable size and direction. With 8 a delivery drum is designated in Fig. 1. A clamping piece 10 is fastened to a gripper shaft 9 by means of a clamping screw 11. A gripper base body 11, which has a closed bearing bore, is brought into contact with the clamping piece 10 by a spring 12. The arrangement of a support plane 14 on the clamping piece 10, the gripper tip 15, the bearing bore 13 of the gripper base body 11 and the spring 12 is chosen so that the effect Lines of the spring force 18, the supporting force 19 and the contact force 20 intersect at the transfer point 22 at the gripper tip 15, ie both when the direction of the resulting resultant 16 is determined by the spring force 18 and the supporting force 19, as well as when the clamping gripper 6 is closed if the resulting resultant 16ʹ is determined by the spring force 18 and the contact force 21. All forces 5, 5ʹ, 16, 16ʹ, 18, 19, 20, 21 thus intersect at the transfer point 22 at the gripper tip 15.

Dadurch wird erreicht, daß die geschlossene Lagerbohrung 13 des Greifergrundkörpers 11 sich stets am Auflagepunkt 17 von oben auf die Greiferwelle 9 anlegt, derart, daß die durch die schädlichen Adhäsionskräfte des Gummituches bewirk­ten Papierzugkräfte sich nicht mehr auf die Mittenverlagerung des Greifergrundkörpers während des Fortdruckes auswirken können.It is thereby achieved that the closed bearing bore 13 of the gripper base body 11 always abuts on the gripper shaft 9 at the support point 17 from above, such that the paper tensile forces caused by the harmful adhesive forces of the rubber blanket can no longer have an effect on the center displacement of the gripper base body during production .

Da sich der Greifer mit minimalen Abstand zum Übergabepunkt 22 am Auflagepunkt 17 zentriert, weist er außerdem ein günstiges Schwingungsverhalten eines kurzen Greifers, wie geringe Amplitude und hoher Eigenfrequenz auf. Beide Vorteile sind von besonderer Bedeutung bei schnellaufenden Maschinen.Since the gripper is centered at a minimal distance from the transfer point 22 at the support point 17, it also has a favorable vibration behavior of a short gripper, such as low amplitude and high natural frequency. Both advantages are particularly important for high-speed machines.

Der im Ausführungsbeispiel (Fig. 3) dargestellte Klemmgrei­fer 6 weist außerdem die bekannten Mittel, wie z.B. eine Klemmschraube 27 auf, die das Klemmstück 10 auf der Grei­ferwelle 9 spannt. Als Lager für die Feder 12 ist an dem Klemmstück 10 ein Ansatz 23 und am Greifergrundkörper 11 ein Ansatz 24 vorgesehen, die sich gegenüberliegen. Mittels einer Einstellschraube 25 am Greifergrundkörper 11 ist die Vorspannung der Feder 12 einstellbar. Die Einstellschraube 25 dient zugleich als Anschlagschraube. Die Feder 12 wirkt mit ihrer Kraft auf den Greifergrundkörper 11 ein und drückt die Einstellschraube 25 gegen die Stützebene 14 am Klemmstück 10.The clamping gripper 6 shown in the exemplary embodiment (FIG. 3) also has the known means, such as a clamping screw 27, which clamps the clamping piece 10 on the gripper shaft 9. As a bearing for the spring 12, an extension 23 is provided on the clamping piece 10 and an extension 24 is provided on the gripper base body 11, which lie opposite one another. The preload of the spring 12 can be adjusted by means of an adjusting screw 25 on the gripper base body 11. The adjusting screw 25 also serves as a stop screw. The spring 12 acts with its force on the gripper body 11 and presses the adjusting screw 25 against the support plane 14 on the clamping piece 10.

Beim Aufschlag der Greiferspitze 15 gegen den auf der Greiferauflagefläche 26 liegenden Bogen 1 wird die Be­rührung der Einstellschraube 25 mit der Stützebene 14 ge­löst und die Federkraft 18 der Feder 12 wirkt als Anpreß­kraft auf die Greiferspitze 15. Mittels Schraube 20 ist die Greiferspitze 15 auswechselbar am Greifergrundkörper 11 angebracht.When the gripper tip 15 strikes against the arch 1 lying on the gripper support surface 26, the contact of the adjusting screw 25 with the support plane 14 is released and the spring force 18 of the spring 12 acts as a pressing force on the gripper tip 15. By means of screw 20, the gripper tip 15 can be exchanged on the gripper base body 11 attached.
