Description

Die Erfindung betrifft eine schaltbare Vorrichtung zur Walzenan- und -abstellung in Farb- und/oder Feuchtwerken von Druckmaschinen, die in zwei Betriebsarten wahlweise automatisch über die Druckschaltung oder von Hand betätigbar ist und bei der ein die jeweilige Stellbewegung bewirkendes Drehmoment mit einer kraftschlüssigen Kupplung mittels eines gefederten, von Hand lösbaren selbsttätig einkuppelnden Verbindungselementes übertragbar ist.The invention relates to a switchable device for roller activation and deactivation in inking and / or dampening units of printing presses, which can be operated in two operating modes either automatically via the pressure circuit or by hand and in which a torque effecting the respective actuating movement is achieved by means of a non-positive coupling a spring-loaded, manually releasable automatically engaging connecting element is transferable.

Eine Vorrichtung dieser Gattung ist aus der Praxis bekannt. Von Nachteil ist, daß die kraftschlüssige Kupplung in beiden Betriebsarten mit dem gleichen Verbindungselement hergestellt wird. Die Kupplung muß hierzu durch raumgreifendes axiales Verschieben eines gefederten Keiles aus einer Nut eines für den automatischen Betrieb vorgesehenen An- und Abstellhebels von Hand gelöst werden, damit die Walzenan- und -abstellung unabhängig von der Druckschaltung mit einem Schalthebel vorgenommen werden kann. Beim Loslassen kuppelt der zuvor gelöste, gefederte Keil unter der Wirkung der Feder wieder selbsttätig ein. Da der gefederte Keil stets in fester Verbindung mit dem Schalthebel bleibt, wird bei automatischer Walzenan- und -abstellung ein an sich unerwünschtes Drehmoment auch auf den Schalthebel für den Handbetrieb übertragen. Für den Bedienenden besteht hieraus eine permanente Unfallgefahr, weil durch den erfaßten Schalthebel Hand und Arm gestaucht werden können, wenn die Walzenan- und -abstellung zufällig gleichzeitig automatisch betätigt wird.A device of this type is known from practice. The disadvantage is that the frictional coupling is produced in both modes with the same connecting element. For this purpose, the clutch has to be released by hand by axially moving a spring-loaded wedge from a groove of a lever intended for automatic operation so that the roller can be switched on and off independently of the pressure circuit using a shift lever. When released, the previously released, spring-loaded wedge engages again automatically under the action of the spring. Since the spring-loaded wedge always remains firmly connected to the shift lever, when the rollers are switched on and off automatically, an inherently undesirable torque is also transmitted to the shift lever for manual operation. This creates a permanent risk of accident for the operator, because the shift lever can be used to squeeze the hand and arm if the roller start and stop are actuated automatically at the same time.

Der Erfindung liegt daher die Aufgabe zugrunde, eine schaltbare Vorrichtung eingangs genannter Gattung zu schaffen, die es ermöglicht, zwischen den Betriebsarten automatischer Betrieb und Handbetrieb in raumsparender Anordnung der kraftschlüssigen Kupplung umzuschalten, ohne dabei mit dem Schalthebel für den Handbetrieb in einem automatischen Betrieb ein Drehmoment übertragen zu können.The invention is therefore based on the object to provide a switchable device of the type mentioned, which makes it possible to switch between the operating modes automatic operation and manual operation in a space-saving arrangement of the non-positive clutch without a torque with the shift lever for manual operation in automatic operation to be able to transmit.

Diese Aufgabe wird gemäß dem kennzeichnenden Teil des ersten Anspruchs gelöst.This object is achieved according to the characterizing part of the first claim.

Der Vorteil der Erfindung besteht darin, daß die Walzenan- und -abstellung oben genannter Gattung mit verminderter Unfallgefahr schaltbar ist und zugleich eine raumsparende Anordnung der kraftschlüssigen Kupplung gewährleistet ist.The advantage of the invention is that the roll start and stop can be switched with reduced risk of accident and at the same time a space-saving arrangement of the non-positive coupling is ensured.

Anhand eines Ausführungsbeispieles wird die Erfindung nachfolgend näher erläutert.The invention is explained in more detail below using an exemplary embodiment.

Es zeigen:

  • Fig. 1 eine schaltbare Vorrichtung zur Walzenan- und -abstellung als Teilansicht, :,
  • Fig. 2 die Vorrichtung gemäß Fig. 1 im Schnitt.
Show it:
  • 1 is a switchable device for the roll on and off as a partial view,
  • Fig. 2 shows the device of FIG. 1 in section.

Zum An- und Abstellen von der Druckform werden die Auftragwalzen eines Farbwerkes in bekannter Weise beispielsweise mittels einer nicht dargestellten Schaltwelle verschwenkt, von der nur ein Koppelglied 1 zur Walzenan- und abstellung dargestellt ist. Die Auftragwalzen sind mit der Druckschaltung gekuppelt und stellen sich mit dem Druck automatisch an und ab. Hierzu ist ein Koppelglied 2, das auf einem Bolzen 3 in einem ersten An- und Abstellhebel 4 gelagert ist, bei Druckan- und -abstellung verschwenkbar. Der erste An- und Abstellhebel 4 ist auf einer Buchse 5 gelagert, die sich auf einer Zylinderpaßschraube 6 befindet, welche innen am Maschinengestell 7 befestigt ist. Ein Arretierbolzen 8 stellt eine formschlüssige Verbindung zu einem zweiten An- und Abstellhebel 9 her, der ringförmig konzentrisch über dem ersten An- und Abstellhebel 4 angeordnet ist. Der Arretierbolzen 8 ist in einer in dem ersten An- und Abstellhebel 4 radial befestigten Lagerbuchse 10 gleitend gelagert und wird unter dem Druck einer Feder 11 gegen eine Gleitfläche 12 an einem am Arretierbolzen 8 vorhandenen Zapfen 19 eines Schaltgriffes 13 gehalten. Der Schaltgriff 13 mit Zapfen 19 ist radial verschiebbar in einem Schalthebel 14 gelagert, der ringförmig konzentrisch über dem zweiten An- und Abstellhebel 9 angeordnet ist. Die Hubgröße der radialen Verschiebbewegung ist mittels einer in einer Nut 20 des Schaltgriffes 13 geführten Rändelschraube 15 exakt begrenzt. Der Schaltgriff 13 bleibt unter der Wirkung der Feder 11 stets in ausgekuppelter Stellung, so daß ein Drehmoment über den ersten An- und Abstellhebel 4, den Arretierbolzen 8, den zweiten An- und Abstellhebel 9 und das auf einem Exzenterbolzen 16 gelagerte Koppelglied zur automatischen Walzenabstellung in raumsparender Anordnung übertragen werden kann, ohne dabei den Schaltgriff 13 zu bewegen. Ein Zylinderstift 17 und ein federndes Druckstück 18 verhindern: zugleich die Drehbewegung des Schalthebels 14. Bei automatischem Betrieb der Walzenan- und -abstellung ist außerdem stets gewährleistet, daß keine Stauch- und Quetschgefahr für Hand und Arm des Bedienenden besteht.To switch the printing forme on and off, the applicator rollers of an inking unit are pivoted in a known manner, for example by means of a switching shaft (not shown), of which only one coupling element 1 is shown for switching the roller on and off. The application rollers are coupled to the pressure circuit and automatically turn on and off with the pressure. For this purpose, there is a coupling element 2 which is on a Bolt 3 is mounted in a first on and off lever 4, pivotable when the pressure is switched on and off. The first on and off lever 4 is mounted on a bushing 5 which is located on a cylinder fitting screw 6 which is fastened to the inside of the machine frame 7. A locking bolt 8 establishes a positive connection to a second on and off lever 9, which is arranged in a ring concentrically above the first on and off lever 4. The locking bolt 8 is slidably mounted in a bearing bush 10 radially fastened in the first actuating and deactivating lever 4 and is held under the pressure of a spring 11 against a sliding surface 12 on a pin 19 of a switching handle 13 provided on the locking bolt 8. The control handle 13 with pin 19 is radially displaceably mounted in a shift lever 14 which is arranged in a ring concentrically above the second on and off lever 9. The stroke size of the radial displacement movement is exactly limited by means of a knurled screw 15 guided in a groove 20 of the control handle 13. The control handle 13 always remains in the disengaged position under the action of the spring 11, so that a torque via the first on and off lever 4, the locking bolt 8, the second on and off lever 9 and the coupling member mounted on an eccentric bolt 16 for automatic roll shutdown can be transmitted in a space-saving arrangement without moving the control handle 13. A cylindrical pin 17 and a resilient pressure piece 18 prevent: at the same time the rotary movement of the shift lever 14. With automatic operation of the roller start and stop, it is also always guaranteed that there is no risk of crushing or crushing the operator's hand and arm.

Wird durch Eindrücken des Schaltgriffes 13 der Arretierbolzen 8 aus dem zweiten An- und Abstellhebel 9 entsprechend dem Hub entfernt und somit die Verbindung aufgehoben, kann der manuelle Betrieb der Walzenan- und -abstellung ausgeführt werden. Hierzu stellt der Zapfen 19 eine kraftschlüssige Verbindung zum zweiten An- und Abstellhebel 9 her. Nach Loslassen des Schaltgriffes 13 rasten der Zapfen 19 mit dem Schaltgriff 13 sowie der Arretierbolzen 8 automatisch in die Ursprungslage zurück, so daß der automatische Betrieb der Walzenan- und -abstellung selbsttätig wieder gewährleistet ist.If the locking bolt 8 is removed from the second lever 9 according to the stroke by pressing the control handle 13 and the connection is thus broken, the manual operation of the roller start and stop can be carried out. For this purpose, the pin 19 establishes a non-positive connection to the second lever 9. After releasing the control handle 13, the pin 19 with the control handle 13 and the locking bolt 8 automatically snap back into the original position, so that the automatic operation of the roller start and stop is automatically ensured again.
