Definitions

the invention relates to a device for correcting the angular deviation the sheet fed to a printing press from a desired position, with a system drum of the printing press through which the fed Sheets are fed to a printing unit of the printing press.
Such a device is an additional device on a conveyor table a sheet feeder known, through which the sheet of the printing press be fed.
a sheet feeder known, through which the sheet of the printing press be fed.
those running parallel to each other Conveyor belts on the conveyor table can be driven independently of one another Tape rolls led.
By driving the belt rolls with different Speed can be the alignment of the conveyor belts transported sheet changed and thus a correction of Angular deviation of the arch from a target position can be achieved.
the separate ones Belt roller drives lead to a very complex and thus expensive construction of the device.
the object of the invention is a device of the type mentioned to create a simple structure and alignment of the individual sheets.
the inclination of the system drum can be easily reached, if the system drum has a split bearing shaft and on each A bearing shaft part of the bearing shaft protrudes from the end face of the system drum and is rotatably mounted in a bearing, at least one of the Bear a bearing that is eccentric to the axis of rotation of the system drum is.
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 supported via a bearing of the bearing shaft part.
the eccentrically adjustable bearing is 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 easily possible in 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, not shown, of the printing press 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 2nd
the system drum 1 is on 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.
