Definitions

  • the invention relates to a device for support of a cylinder in a rotary printing press.
  • the device includes a hydraulic cylinder on the Floor is pivoted. Via a piston rod, a tension screw and a yoke acts hydraulic cylinders with an extension piece the roller to be kept in balance. That with the piston rod via a clamping screw connected yoke is on the extension of the roller to be kept in balance via a ball bearing rotatably mounted.
  • the hydraulic cylinder holds it Roller in a position in which work on the Roller can be carried out without further disassembly can.
  • DE 40 36 388 A1 discloses a bearing for one Printing unit cylinder of a web-fed rotary printing press with a replaceable one, axially from the cylinder drawable coat.
  • This is outside and / or inside the machine side wall supporting the journal of the cylinder on the pegs one supporting the cylinder
  • Adjustable lever which is rotatably mounted in the frame, lying perpendicular to the support surface next to the peg has an eccentric and by means of a four-bar linkage with another on the other side of the tenon eccentric mounted in the frame is connected.
  • a disadvantage of the device disclosed in US 4,119,032 is the lack of protection against pressure drop in the hydraulic system. As a result of gravity the roller would drop if there was a pressure drop in the hydraulic system by their own weight in the side wall, in which it is still stored, may be bent. This has costly Assembly work or a replacement of the Warehouse.
  • a device according to the preamble of claim 1 is both known from document DE-A-40 08 501 and from document DE-A-40 36 388.
  • the object is characterized by the features of claim 1 solved.
  • a printing unit comprises a pair of printing cylinders, a Pair of bearings including bearings for the Impression cylinder and a pair of counterweight mechanisms for the impression cylinder.
  • Any of the counterweight mechanisms includes an actuator and a through the adjusting cylinder rotatable joint piece.
  • the joint piece is by a clamping screw with the rotating arm connected so that the rotary arm when the Actuating cylinder is rotated.
  • the swivel arm is in the side frame the press is stored in one position, which are relative to the associated impression cylinder is adjustable, and by means of the clamping screw additional adjustment of the position of the rotary arm relative be made to the joint piece.
  • the joint pieces are in end positions movable. If the joint pieces are in their End positions, then the movement of the Swivel arms from their support positions under the weight the printing cylinder is blocked. The rotating arms remain in their support positions, even if the pressure in the Cylinders falls off.
  • the pivot arms are in and out its support position movable so that the counterweight mechanisms only if necessary to the assigned Printing cylinders can be operated. Consequently bearing friction and bearing wear on one Minimum reduced.
  • a control device for automatic Operating the counterweight mechanisms can be removed by removing the carrier in the bearings the other ends of the pressure cylinder are activated.
  • a printing unit 10 comprises a frame with a pair spaced apart Sidewalls 12 and 14.
  • the journals 20 of the pressure cylinder 16 are with a storage Support elements 26 in the side walls 12 and 14 rotatably supported.
  • the pivot 22 of the other Printing cylinders 18 are from another storage with support elements 28 in the side walls 12 and 14 rotatably supported.
  • Which is on the right side of the Carrier elements 26 and 28 located in the printing unit 10 can move away from their positions in the side wall 14 as shown in Fig. 1 to access the right ends of the impression cylinders 16 and 18 to create an opening 30 in the side wall 14.
  • the Printing form sleeves 32 and 34 can then of the Printing cylinders 16 and 18 are removed by this through the opening 30 axially from the pressure cylinders 16 and 18 are drawn.
  • the central mounting plate 44 is through Holder 48 and bolt 49 on a flange 46 on the Side wall 12 attached.
  • Each of the upper and lower counterweight mechanisms 40 and 42 has a rotary arm 50.
  • Each pivot arm 50 is through an adjustment of pivot pins 52 connected to the central mounting plate 44.
  • the pivot pin adjustments 52 allow this Rotating the pivot arms 50 around the pivot pin bearing, what an adjustment of the positions of the rotary arms 50 in horizontal direction and thus a horizontal positioning the journals 20 and 22 on the right Side of the printing unit 10 allows.
  • Each swivel arm 50 has an arched holding surface 54 which during rotation of the pivot arm 50 around the pivot pin bearing 52 in contact and out of contact with the associated Bearing pin 20 or 22 is movable.
  • Tensioning screws 56 rotatably connected.
  • the tension screws 56 allow vertical positioning of the Journal 20 and 22 on the right side of the printing unit 10.
  • the clamping screws 56 are triangular Joint pieces 60 rotatably connected.
  • the joint pieces 60 are around third bolts secured in side wall 12 64 rotatable.
  • the upper and lower counterweight mechanisms 40 and 42 also include an actuator cylinder 66 and a piston rod 68.
  • the actuating cylinder 66 is around a bolt 70 fastened in the side wall 12 is rotatable.
  • the end of the piston rod 68 is through a bolt 72 rotatably connected to the joint piece 60.
  • the top and bottom are Counterweight mechanisms 40 and 42 between one Closed position shown in solid lines and one shown partially in dashed lines open position movable.
  • the piston rod 68 When moving from the open position shown in dashed lines to the closed position shown in solid lines moves the piston rod 68 into the actuating cylinder 66 until it is stopped by a stop 74.
  • the Joint piece 60 is around the bolt 64 in Turned counterclockwise.
  • the arched holding surface 54 on the respective rotary arm 50 is thus in the Contact with the trunnions 20, 22 on the pressure cylinders 16 and 18 brought. While in contact with the pivot pins 20 and 22 exercise the respective rotating arms 50 on the respectively assigned journal 20 or 22 a counterweight pressure by which the associated pressure cylinder 16 or 18 when removing the support elements 26 and 28 is supported, as in Fig. 1 shown.
