Definitions

  • the invention relates to a switchable device for switching rollers on and off in inking and / or dampening units of printing presses, which can be operated automatically in two operating modes either 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.
  • 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.
  • 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.
  • 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 gearshift lever, when the rollers are switched on and off automatically, an inherently undesirable torque is also transmitted to the gearshift 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 rollers and shutters are accidentally actuated at the same time.
  • 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.
  • 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.
  • 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.
  • a coupling member 2 which is mounted on a pin 3 in a first on and off lever 4, can be pivoted 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 which is 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 control lever 14, which is arranged concentrically in a ring above the second up and down 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 actuating and deactivating lever 4, the locking bolt 8, the second actuating and deactivating lever 9 and the coupling member 1 adjustably mounted on an eccentric bolt 16 automatic roller shutdown un space-saving arrangement can be transmitted without moving the control handle 13.
  • a cylinder pin 17 and a resilient pressure piece 18 also prevent the rotary movement of the shift lever 14. With automatic operation of the roller and shutdown, it is also always ensured that there is no risk of crushing and crushing the hand and arm of the operator.
  • 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 and shutdown is automatically ensured again.
