Definitions

  • the invention relates to a pivotable ink knife carrier in rotary printing machines according to the preamble of claim 1.
  • a generic swiveling ink fountain carrier without ink fountain in a rotary printing press has become known from GB-A-6 05 092.
  • the ink knife holder can be swiveled around a horizontal one Swivel axis. It is so spaced from the center of gravity of the ink knife carrier that it becomes top-heavy when swiveled against a duct roller.
  • the ink knife carrier, the duct roller and a film roller are stored together in two bearing blocks.
  • the ink knife carrier has ink knives, the underside of which forms a metering gap with the duct roller.
  • the invention has for its object to provide an ink knife holder which can be easily adjusted by swiveling it to a color duct, the position of which in its working position can be reproduced exactly and automatically.
  • the ink knife carrier can be operated remotely and thus, can no longer be influenced by the operator, can be adjusted exactly to the intended working position on the ink fountain roller.
  • the effort required to actuate the ink knife carrier is low since the axial center line running through the axle journals of the ink knife carrier runs in the vicinity of the center of gravity of the ink knife carrier.
  • Automatic and remote-controlled locking of the ink knife holder in the swiveled-in working position guarantees that the machine will only run after it has been locked.
  • the holders can be exchanged quickly if necessary.
  • the ink knife carrier 1 which is designated overall by 1, is shown in front view and partially in section.
  • the ink knife carrier 1 consists of a housing 2, which accommodates a total of four brackets 3, each of which contains zoned drives for adjusting the ink knife 4.
  • the brackets 3 are fastened to the housing 2 by means of screws 5.
  • the drive is only indicated in a holder by a motor 48 and is shown in more detail in FIGS. 4 and 7.
  • the ink knife carrier 1 is with journal 6; 7 connected by screws 8.
  • the journal 6; 7 are in bearing blocks 9; 11 stored, the bearing blocks 9; 11 are attached to a cross member 12 by means of screws 13.
  • the cross member 12 is connected to the side walls of the machine frame, not shown.
  • the ink knife carrier 1 has holes 14 on its end faces; 16, in the locking bolt 17; 18 with their respective first ends 19; 21 intervene.
  • the locking bolts 17; 18 are 22 at their second end; 23 each with a gear 24; 26 firmly connected.
  • the locking bolt 17; 18 are on the one hand in the bearing block 9; 11 and on the other hand in bearings 27; 28 attached.
  • the locking bolt 17; 18 have in their between the first end 19; 21 and the second end 22; 23 located middle part an external thread 29; 31 on that in a threaded bore 32; 33 of the bearing block 9; 11 is movable.
  • the gear 24 of the locking bolt 17 meshes with a gear 34 which is directly connected to the drive shaft of a motor 36 fastened on the bearing block 9.
  • the gearwheel 26 of the locking bolt 18 meshes with a gearwheel 37, the gearwheel 37 with its internal thread 35 being in operative connection with an external thread 40 of the axle journal 7.
  • the gear 37 has a fixed stop 38 and meshes with a gear 39 of a motor 41 which is fastened on the bearing block 11.
  • the end of the journal 7 facing away from the housing 2 receives a disk 42 with a stop 43 fixedly arranged thereon.
  • the disk 42 is connected to the side of the axle 7 facing away from the housing 2 by screws 44.
  • the ink knife carrier 1 is shown in section and shows a drive for the adjustable ink knife 4, which is clamped on one side by means of a bar 46 and screws 47 on the housing 2 of the ink knife carrier 1.
  • Each of the brackets 3 according to FIG. 1 is equipped with several actuating units in accordance with the format of the machine; here marked with engine 48.
  • the motor 48 is provided on its drive shaft 49 with an eccentric disk 51.
  • the Eccentric disc 51 acts on the ink knife 4 via a lever 52, which is pivotably mounted on the holder 3 at point 53.
  • the lever 52 engages through a bore 54 in the housing 2.
  • the holders 3 can be detached from the housing 2 via screws 56 connected. The exact position of the brackets 3 is ensured by stops, not shown, in the ink knife carrier 1.
  • the ink knives 4 interact with their underside in each case with one of the 1/4 wide ink fountain rollers or ductors 56 in such a way that they form an ink metering gap.
  • the circumference of the ductor 56 is connected to a film roller 57.
  • a paint applicator bar 58 is arranged in front of the ductor 56, each of which is connected to an ink reservoir (not shown) via a paint guide 59.
  • the ductor 56 and the film roller are each on both sides in the bearing blocks 9; 11 stored.
  • the ink knife carrier 1 is initially in the working or operating position shown in FIGS. 1 to 4, ie the ink knife 4 is connected to the ink applied by the ink application bar 58 to the ductor 56.
  • the signal for pivoting the ink knife carrier 1 is given from a central point, for example from a machine control station (not shown).
  • the motor 36 receives a pulse and is set in rotary motion so that the gears 34 and 24 mesh with one another and thus the locking bolt 17 comes into contact with the threaded bore 32 via its external thread 29 and moves outward in the direction of arrow C.
  • a switch 61 is actuated, which triggers a pulse for actuating the motor 41 with its firmly connected gear 39.
  • the starting position is as shown in FIGS. 2 to 4.
  • gear 39 located on the shaft of the motor 41 in the direction of arrow D according to FIG. 3
  • the gear 37 with its stop 38 is set into a corresponding rotation. 2
  • the gear has a distance a from the disk 42 so that the stop 38 moves past the stop 43. Since the hub of the gearwheel 37 is connected to an internal thread 35, the gearwheel 37 moves in the direction of the arrow E according to FIG. 2, so that the distance a is reduced and the stop 38 lies behind the stop 43 after an extensive rotation of the gearwheel 37 is coming. This is shown by the hatched representation of the stop 38 as position 38 'in FIG. 3.
  • the distance a between the gearwheel 37 and the disk 42 has decreased from FIG. 3 to the distance b according to FIG. 5.
  • the color knives 4 can now be easily cleaned and, if necessary, the color application bar 58.
  • the procedure is as follows: According to FIGS. 5 and 6, the motor 41 receives a pulse from a central point and starts up. The gear 39 thus rotates in the direction of the arrow F. The gear 37 meshing with the gear 39 with the stop 38 also rotates in the direction of the arrow F '. The stop 43 with the disk 42 follows the stop 38 tightly in the direction of the arrow F ', since the pivot axis 60 is so close, ie at a distance h, z. B.
  • the ink knife carrier 1 is arranged so that the part of the ink knife carrier 1, which carries the brackets 3 and the drives, is slightly overweight, ie slightly top-heavy, so that the ink knife carrier according to FIG. 7 the effort has to perform a pivoting movement automatically in the direction of arrow G.
  • the ink knife carrier 1 thus pivots from its position shown in FIG. 7 in the direction of arrow G into the position shown in FIG. 4. This means that the center of gravity S also travels a path from the I. to the IV. Quadrant, based on a coordinate system whose origin lies on the axis of rotation 60 of the ink knife carrier 1.
  • the threaded locking bolt 18 has made a movement in the direction of the housing 2 due to the meshing of the gear 37 with the gear 26, and the locking bolt 18 has moved with its first end 21 into the locking position in the bore 16.
  • the motor 41 is switched off by a switch 62 arranged in the bore 16 and the motor 36 is switched on for the purpose of locking by means of locking bolts 17 in the bore 14.
  • the zonal control units 48 fixed on the brackets 3 can be preset in the disassembled state; this can greatly simplify assembly.
