Definitions

  • the invention relates to a device for correcting the angular deviation the sheet fed to a printing press after the generic part of the Claim 1.
  • Such a device is an additional device on a conveyor table Sheet feeder known through which the sheets are fed to the printing press become.
  • the conveyor belts running parallel to each other are Belt table guided over belt rollers that can be driven independently of one another. By the belt rollers can be driven at different speeds Alignment of the sheets transported on the conveyor belts changed and thus a correction of the angular deviation of the sheets from a target position can be achieved.
  • the separate drives of the tape rolls lead to a very complex and therefore expensive structure of the device.
  • the printing press has one Sheet feed drum, which is directly between a feed table and a Printing cylinder is arranged. To compensate for skewing of an image in A sheet can be fed to a printing unit by tilting the Sheet feed drum can be rotated in its plane.
  • the sheet guide drum has a rigid shaft. The inclination is done by means of an eccentric Bearing ring on the side of the sheet guide drum assigned to the rotary drive.
  • a sheet transport drum has become known from EP 0453789 A1, whose axis is immovable at one end and translational at the other end is movably mounted.
  • the sheet transport drum is designed so that the sheets transporting elements opposite the axis of the fixed Drive gear are inclined. The application of this technique is only for Sheet transport drums between printing units described.
  • the object of the invention is therefore to a device of the type mentioned create that has a simple structure and an orientation of each Allows bow.
  • the inclination of the system drum can be easily achieved if the Has a split bearing shaft and on each end face of the System drum protrudes a bearing shaft part of the bearing shaft and in a bearing is rotatably supported, at least one of the bearings being eccentric to the axis of rotation the feed drum is adjustable storage.
  • the system drum can have at least one of the bearing shaft parts non-rotatably connected, and from a coaxial position to the bearing shaft part in an inclined position deviating from the coaxial position can be pivoted.
  • the spring element can be a spring washer, with its radially outer area with the System drum and with its central area with the bearing shaft part connected is.
  • One of the bearing shaft parts can be used for stable guidance of the bearing of the system drum be rotatably mounted in a fixed bearing, the stationary bearing shaft part can be rotatably driven.
  • the eccentrically adjustable bearing is also stable thereby achieved that the eccentrically adjustable bearing an eccentric ring has, the circular bore contour and radially circumferential Outer contour are eccentric to each other, the one with its outer contour rotatably mounted in a fixed component and in its Bore is rotatably mounted on a bearing of the bearing shaft part.
  • eccentrically adjustable bearing an eccentric bearing with a eccentric bearing ring is around the axis of rotation of the bearing shaft part is rotatably mounted in a fixed component.
  • the eccentrically adjustable storage can be done manually as well be adjustable by electric motor.
  • An automatic alignment is on simple way possible that the electromotive adjustment by a control unit depending on the angular deviation of the supplied sheet can be controlled from the target position.
  • a plant drum 1 of a printing press has on its end faces protruding bearing shaft parts 2 and 3.
  • the bearing shaft part 3 is coaxially rigidly connected to the system drum 1 and a bearing 4 in a bore 6 of an eccentric ring 5 rotatably mounted. Both the hole 6 and the outer contour 7 of the eccentric ring 5 have one circular cross section.
  • the eccentric ring 5 With its outer contour 7, the eccentric ring 5 is in turn in a bore 8 of a wall 9 of the machine frame of the printing press can be rotated stored.
  • the eccentric ring 5 can be rotated in the bore 8.
  • the bearing shaft part 2 is in a further wall via a second bearing 14 13 of the machine frame rotatably mounted.
  • a drive gear 15 arranged by the drive of the printing press, not shown is rotatably driven.
  • the bearing shaft part 2 is with its abutment drum end Spring washer 10 non-rotatably connected, which is fixed in the radially outer edge region is arranged on one end of the plant drum 1.
  • the End of the bearing shaft part 2 on the drum side protrudes into a coaxial Recess 11 of the contact drum 1, the diameter of the Recess 11 is significantly larger than the diameter of the bearing shaft part Second
  • the contact drum 1 is over the spring washer 10 rotatably connected to the bearing shaft part 2, but can by axial elasticity of the spring washer 10 from a coaxial position to the axis of rotation 12 of the bearing shaft part 2 are pivoted out. This happens by turning the eccentric ring 5 in the bore 8 the system drum 1 from a coaxial normal position of its axis of rotation 16 to the axis of rotation 12 of the bearing shaft part 2 in a deviating from the normal position Inclined position, which is indicated by the broken line 18 is shown.
