Definitions

  • the invention relates to an oscillating application roller in an inking unit of a rotary printing press.
  • an oscillating inking roller which carries out a lateral movement with a friction roller, from which the drive of the application roller is derived by friction.
  • the roller jacket of the oscillating inking roller is rotatably and axially displaceably mounted on a roller axis arranged in a rotationally fixed manner in bearings, the axial stroke being limited on both sides by two bushes.
  • the disadvantage is that the traversing movement cannot be deactivated. In a very large number of cases, it is not necessary to traverse the application rollers at all.
  • EP-A-02 67 504 shows an iridescent applicator roll, the roll journals of which are mounted in a bearing sleeve both rotatably and axially displaceably. Its stroke is adjustable as well as on and off.
  • the invention has for its object to provide a device driven by friction, rotatably and axially displaceably mounted on an axially displaceable roller with which the friction stroke can be switched on and off.
  • the friction stroke can be switched on and off both while the machine is running and when the machine is at a standstill.
  • the further advantage of the invention is in particular that conventional roller locks can be used, i.e. Printing presses already in use can be retrofitted without any effort.
  • An operator can switch the friction stroke on and off without having to pay attention to the traversing cycle of the application roller.
  • An inking unit 1 of a rotary printing machine has i.a. a number (e.g. 2) of rotatably mounted friction rollers 2, each with a drive (not shown) for a lateral movement of the friction roller 2.
  • the friction rollers 2 are in frictional engagement with a number (e.g. 4) application rollers 3, which in turn are in contact with the surface of a plate cylinder 4 or printing plates arranged thereon.
  • the structure of the application rollers 3 is the same and is therefore only described using an application roller 3.
  • the application roller 3 has a roller axis 6, which is mounted in roller locks.
  • the roller locks are located in a known manner in pivotally mounted levers, so that the application rollers 3 can be switched off from the plate cylinder 4.
  • a casing tube 7 with a rubber cover is rotatably and axially displaceable by means of two combined radial-axial bearings 8, 9.
  • a lateral stroke of the casing tube 7 is limited on the left side by a stop ring 11 fastened on the roller axis 6.
  • a left race 12 of the radial axial bearing 8 abuts a stop surface 13 of the stop ring 11.
  • the axial stroke (approx. 7 to 8 mm) is limited by a sliding ring 14.
  • a right-hand race 16 of the radial axial bearing 9 abuts against a stop surface 17 of the sliding ring 14.
  • the sliding ring 14 is mounted on the roller axis 6 so as to be pivotable and axially displaceable as part of an adjusting device 18.
  • the adjusting device 18 also has an adjusting ring 19 and a bearing ring 21.
  • the adjusting ring 19 coaxially surrounds the adjusting device 18 and is pivotally and axially displaceably mounted on the sliding ring 14 and the bearing ring 21.
  • the pivoting movement of the adjusting ring 19 is limited in the circumferential direction by a radially inwardly oriented first guide pin 22 attached to the adjusting ring 19.
  • the guide pin 22 engages in an annular groove 23 in the sliding ring 14.
  • a spiral spring 24 e.g. compression spring
  • the annular groove 23 is so wide (e.g. 10 mm) that an axial movement of the guide pin 22 is possible.
  • the sliding ring 14 and the bearing ring 21 are arranged side by side on the roller axis 6 and are in lateral contact with one another via control surfaces 31, 32.
  • the control surface 31 of the sliding ring 14 is aligned axially to the right
  • the control surface 32 of the bearing ring 21 is aligned axially to the left.
  • the Control surfaces 31, 32 each have a number of mountains 33, 34 and valleys 36, 37.
  • a mountain 33 of the control surface 31 of the sliding ring 14 lies against a valley 37 of the control surface 32 of the bearing ring 21 and, conversely, a mountain 34 of the control surface 32 lies against a valley 36 of the control surface 31.
  • a mountain 33 of the control surface 31 bears against a mountain 34 of the control surface 32.
  • the valleys 36, 37 of the control surfaces 31, 32 have a distance a (e.g. 16 mm) from one another which is twice as large as the stroke h (e.g. 8 mm).
  • the races 12, 16 rest against the stop surfaces 13, 17, so that a traversing movement of the roller tube 7 is blocked.
  • the roller tube 7 is located outside of a central position relative to the plate cylinder 4.
  • the adjusting device 18 is arranged on both sides of the roller axis 6 (in this case the bearing ring 11 is omitted), it is of course also possible to fix the casing tube 7 in the central position.
  • the control surfaces 31, 32 would of course have to be changed such that a height distance between mountain 33, 34 and valley 36, 37 is halved.
  • the collar 19 can be provided with known actuators, so that an automatic adjustment or remote adjustment is made possible.
  • the adjusting ring 19 In order to move the sliding ring 14 or the roller tube 7 from the traversing position "I" to the switch-off position "O", the adjusting ring 19 must be rotated by an angle ⁇ (eg 45 o ) and then by a small distance (eg 5 mm) to the left (Fig. 5,6).
  • the guide pin 27 slides upward in the guide groove 28 and engages in the axially extending portion 30 of the groove 28.
  • the guide pin 22 slides upward in the annular groove 23 and takes the sliding block 25 and the spiral spring 24 supported thereon with it.
  • the coil spring 24 acts without significant bias on the stop 26 and rotates the sliding ring 14. This is supported with its control surface 31 on the control surface 32 of the bearing ring 21 and is thereby shifted axially to the left in the switch-off position "O".
  • the sliding ring 14 tends to perform a pivoting movement and to move axially to the left via the control surfaces 31, 32. Therefore, the stop surface 17 of the sliding ring 14 follows the race 16 when it moves entrained by the distributor roller 2 to the left and fixes the casing tube 7 in the switch-off position "O" when the mountain 33 abuts the mountain 34 of the control surfaces 31, 32.
  • the adjusting ring 19 is first shifted axially to the right and then pivoted back by the angle ⁇ .
  • the guide pin 22 moves into an axially extending part 39 of the annular groove 23 and takes the sliding ring 14 with the pivoting movement of the adjusting ring 19, whereby it is supported on a bolt 38 fastened to the sliding ring 14 until the mountain 33 on the valley 37 and the mountain 34 abuts the valley 36.
  • a stop 41 protrudes into the annular groove 23 and prevents the sliding block 25 from blocking the annular groove 23 in the region of the portion 39.
