Definitions

  • the invention relates to a sheet transfer drum between the printing units of rotary printing presses according to the preamble of claim 1.
  • the object is achieved by the characterizing features of claim 1.
  • guiding surfaces which are provided in the drum body between the rows of grippers, a space is created in which the rear end of the rigid sheet can relax without damaging the printed side. After the transfer to the next cylinder, the trailing edge of the sheet is directed along the guide plates.
  • baffles act as air blades which, in conjunction with the air build-up generated in the wedge-shaped cavity, keep the sheet with its printed surface away from the baffles.
  • a sheet transfer drum 1 is provided between the printing units of a rotary printing machine arranged in series, which transfer the printed sheets 2 from one Take over printing cylinder 3 and deliver it to the next printing cylinder 4 of the next printing unit.
  • rows of grippers 5, 6, 7 are provided on the sheet transfer drum, which take over the sheets from the grippers of the printing cylinder 3 and transfer them to the grippers 8 of the subsequent printing cylinder 4.
  • the cylinders and the drums are mounted in a known manner between the machine side frames and are coupled in terms of drive via a spur gear drive.
  • the sheet transfer drum 1 consists of an axis 9 rotatably mounted in the machine side frames, not shown, on each of which a support body 10 is fastened.
  • the support body 10 can be designed as a drum body with axle journals.
  • the gripper support rails 11 for the gripper rows 5-7 are fastened on the support body 10 via the bearing body 12.
  • the grippers are controlled in a known manner, e.g. over curves and cam rollers, so that the fed sheet is taken over in the center between printing cylinder 3 and sheet transfer drum 1 and delivered in the center between sheet transfer drum 1 and printing cylinder 4.
  • guide plates 14 are provided within the drum circumference between the gripper rows 5-7, which are shaped inwards towards the center of the drum in such a way that they form a cavity for generating an air jam.
  • the guide surfaces of the guide plates 14 run essentially as a secant to the drum circumference and have a deflection towards the center of the drum.
  • the baffles 14 are attached to the bearing bodies 12 and the brackets 15 for the arch support elements 13. The attachment can be e.g. by means of screws 16.
  • the sheet guiding device 17 is fastened on both sides to the machine side frames in a known manner.
  • the guide plates 14, together with the rear end of the sheet 2 form a narrowing wedge-shaped cavity 18 in which an air jam is generated. This air jam prevents the printed sheet surface from striking the guide plate 14. Only the rear sheet edge is guided along the guide plate 14 by the rotary movement of the sheet transfer drum and the printing cylinder. If slots 14 are provided in the area of the fastening screws 16 for the guide plates, these can be adjusted and thereby adapted to different types of paper.
  • a blow pipe 19 is provided between the sheet transfer drum and the pressure cylinder 4, the air flow 20 of which is directed into the wedge-shaped cavity and reinforces or supports the air congestion.
  • guide plates 14 guide brackets or guide tongues can also be used if e.g. only very stiff cardboard is processed.
  • openings can be provided on the guide plates 14, e.g. in the form of closable air vents, whereby the air pressure can be adapted to different materials.
  • Fig. 3 for processing thin soft sheets 2 are inserted into the sheet transfer drum 1 between the gripper rows 5, 6 and 7 sheet support members 13 which form the cylinder jacket with their wings.
  • the wings can be designed so that they take no color from the freshly printed sheets.
  • the guide plates 14 can remain in the sheet transfer drum 1 below the sheet support elements during this printing work.
  • the arch support elements 13 can be continuous over the cylinder length or can be designed as webs, and are hooked on one side via bolts 21 into a slotted holder 22. On the other hand, they are also suspended in the fork-shaped receptacle of the holder 15 via a bolt 23 and secured by a hook 24.
  • the hook 24 is fastened on a spindle 28 and is pivoted into its holding position under spring force.
  • a pivot lever 29 is attached to one side of the spindle 28, which carries a spring pin 25.
  • the bolt 23 automatically opens and engages the hook 24.
  • the spring bolt 25 snaps into a hole in the arch support element 13 for additional securing.
  • the spring bolt 25 is unlocked and over the Swivel lever 29 of the hook 24 opened so that the sheet support member 13 can be removed.
  • Fig. 4 differs from the previously explained embodiments in that the sheet transfer drum 1 has a drum body 26 which has a guide surface 27 corresponding to the guide plates 14 between the gripper rows 5, 6 and 7.
  • the same advantages and effects are achieved as with the guide plates 14, and in addition sheet support elements 13 can be used in the same way if the printer wants to process a corresponding print job.
