Definitions

  • the invention relates to a sheet transport drum according to the preamble of patent claim 1.
  • Such a device is known from DE-OS 3 400 652.
  • a device of this type is known from DE-OS 3 400 652.
  • a correction cylinder on its operating side should be able to be adjusted relative to its target position.
  • the axis of the correction cylinder as a whole is inclined with respect to the neighboring cylinders.
  • the reason given for the position of the inclined device on the operating side is that better operation and less mechanical effort are required in the construction.
  • the device has the disadvantage that it does not avoid effects on the transmission due to the inclination.
  • the displacement of the cylinder be it directly on the transmission side or also on the opposite side, which the relevant position is not known, will always cause an inclination, in the worst case even a displacement of a gearwheel in the drive train relative to the neighboring gearwheels. This compensates for the problem of improving sheet transfer by worsening the conditions in the drive train.
  • DE-C1 37 04 314 describes an arrangement for adjusting the tooth play between the drive gear wheels of sheet-transporting cylinders and drums of sheet-fed rotary printing machines.
  • Eccentric bearing bushes are provided on both sides for the storage of all the drums mentioned. They are used to move the drums in parallel to adjust the tooth play in the drive. An inclination of the drums is not provided and cannot be carried out without disadvantage for the drive conditions.
  • the aim of the invention is not to worsen the drive conditions through additional measures in the area of the register setting.
  • the invention is therefore based on the object of providing means in a device according to the preamble of patent claim 1 which prevent a change in the drive conditions by inclining a sheet transport drum.
  • the shaft of the sheet transport drum can be provided with axially movable but radially and circumferentially rigid elements relative to the drive-side bearing.
  • an inclined drum body which is rigidly mounted in the circumferential direction can be provided on a rigid drum shaft.
  • a sheet transport drum 1 is shown according to the invention.
  • the sheet transport drum 1 consists essentially of a drive pin 2 and a shaft pin 3 with supporting disks 4, 5 flanged thereon. Between the supporting disks 4, 5, gripper bars 6, 7 are provided for attaching gripper devices for sheet transport.
  • Bearings 8, 9 are provided in the machine wall 10 for drive 2 and shaft journals 3.
  • a drive gear 11 is fastened on the drive pin 2.
  • a positioning eccentric 12 is additionally provided on the bearing 9, with the aid of which the axis of the sheet transport drum 1 can be pivoted. By rotating the positioning eccentric 12 with the aid of an actuator (not shown here), the position of the axis is inclined relative to the normal position about a pivot point S. This is shown by the double dash-dotted line.
  • the pivot point S lies on the drum axis at the inner edge of the drive pin 2. Because of the connection within the sheet transport drum 1 that too Drive gear 11 would be inclined, a small amount of axially movable decoupling is provided in the transition between the support plate 4 on the drive side and the drive pin 2. In the direction of rotation and radially, however, the coupling point is designed so rigid that no movement is possible.
  • FIG. 2 The design of the coupling point in the connection between the support plate 4 and the drive pin 2 is shown in FIG. 2.
  • the drive pin 2 carries the gear 11 and is guided in the bearing 8.
  • the support disk 4 is placed on its inner end. It is connected to the drive pin 2 with the aid of an annular coupling membrane 13.
  • the coupling membrane 13 is connected to the inner end face of the drive pin 2 and the inner circumference of the support disk 4 with a uniformly distributed set of connecting screws 14. As a result, the support disk 4 is held flush with the drive pin 2, axial movements being largely avoided. On the other hand, however, a bend can be made around the connection defined by the coupling membrane 13.
  • FIG. 4 shows a variant for the inclination of a drum body on a continuous drum shaft 16.
  • the drum body with support disks 17, 18 is mounted at two points on the drum shaft 16, the support disks 17, 18 being rigidly connected to the drum shaft 16 in the circumferential direction.
  • a setting eccentric 19 is provided between the support disk 18 and the drum shaft 16, with the aid of which the drum body can be inclined relative to the drum shaft 16.
  • this is provided with an arcuate bearing surface 20 opposite the drum shaft 16.
  • the support disks 17, 18 are with flanges 21, 22 on the Mounted drum shaft 16 and rigidly coupled with bolts 23, 24 to the drum shaft 16 in the circumferential direction.
  • An actuator required for this can be arranged circumferentially on the support disk 18 or stationary on the machine frame 25 with a coupling gear guided through the drum shaft 16.
