Definitions

  • the invention relates to a method and a device for securing and guiding Sheets in sheet delivery of printing machines.
  • Non-stop operation means that when the sheet stack is full an auxiliary pad is retracted over the stack while moving out of the full stack of sheets and until an empty stack pallet is set, the ones to be deposited Bow temporarily picks up.
  • One problem when changing sheets is the one on top the full stack of sheets lying when inserting the auxiliary stacking table and can slip when lowering the sheet stack. This is due to air pockets under the arches on which the arches "float".
  • Stack compressors are known which are permanent and / or after completion of the stack formation act on the sheet stack from above so that the air escapes from the sheet stack.
  • a non-stop delivery device for a printing press which one or more hold-down devices are arranged in the area of the front edge of the main stack below the guides for an auxiliary stack support.
  • the hold-down devices are pivoted onto the upper sheet of the full sheet stack at the start of the stack change.
  • the air hold-ups are pushed out in the front area of the sheet stack by the hold-down device and the auxiliary stack pad is inserted over the sheet stack without damage to the sheet, since the sheet is pressed and held by the hold-down device.
  • the arrangement of stack guides - front and back - enables the stack guides to be controlled from the park position to the working position at the start of the stack change - when the auxiliary stacking table is pushed in - and the sheets on the top of the sheet stack are secured in two levels against slipping or moving become.
  • the sheets are secured by the stack guides against shifting when the auxiliary stacking table is retracted and when the sheet stack is lowered.
  • the stack guides as corner holders (front edge of the sheet stack) and alignment plate (rear edge of the sheet stack) and the displaceable arrangement of the corner holders as well as through the oscillating arrangement of the alignment plate, it is possible to adjust the stack guides to any sheet format.
  • Fig. 1 shows the sheet boom in partial view in a side view and Fig. 2 shows the top view acc. Fig. 1, two sheet formats are shown in Fig. 2.
  • the sheet delivery is known per se, for example from DE 196 49 341 A1 mentioned in the prior art of this patent application and therefore not shown and described again here.
  • 1 and FIG. 2 show the chain circle 1 with the gripper carriage 2, which convey the sheet 3 over the sheet stack 4, the auxiliary stack 6 carried by the non-stop roller blind 5 (auxiliary stacking table), and the suction roller 7 on the rear edge 27 of the sheet stack 4 and the front sheet stops 8 on the front edge 26 of the sheet stack 4.
  • the sheet stack 4 is on the pallet 13, which in turn is on the stacking plate 10 and is assigned to the stack elevator 9.
  • a stack guide 11, 12 is arranged, which is provided on both sides of the sheet stack 4.
  • the stack guide 11 on the front edge 26 has the following structure.
  • a guide 23 is mounted on the frame 22, which is arranged on the frame 22 across the width of the sheet boom, so that it can be moved and locked.
  • a working cylinder 19 is mounted on the guide 23, on the piston rod 24 of which a corner holder 25 which is open by approximately 90 ° is arranged.
  • the corner holder 25 can be controlled in a parking position A (drawn thinly) - outside the stacking plate 10 - or in the working position B (drawn heavily).
  • the corner holder 25 lies loosely against the sheet corners 28 in the working position B.
  • the stack guide 12 at the rear edge 27 has the following structure.
  • a traverse 15.1 is provided, on which a holder 17 and a working cylinder 19.1 are movably mounted in the pivot point 18.
  • the working cylinder 19.1 engages an alignment plate 20 which is connected to the holder 17 in a pivotable manner at the pivot point 21.
  • the alignment plate 20 is shown in dashed lines in the position A - parking position and as a solid line in the position B - working position. In the park position A, the alignment plate 20 is located outside the stacking plate 10.
  • the stack of sheets 4 shows the stacking of sheets of two different formats F 1 , F 2 . An adjustment of the stack guide 12 to the processing of different formats is not necessary.
  • the part of the corner holder 25 and the alignment plate 20 acting on the sheet stack 4 - recognizable from FIG. 1 - has a length L in the vertical plane which is dimensioned so large that a part of the sheets 3 lying on top of the sheet stack 4 is completely lowered Sheet stack 4 can still be saved.
  • the security and management process is as follows: Before the start of printing, the stack guide 11 is set to the format F 1 , F 2 to be processed. For this purpose, the guide 23 is released from the cross member 15 and the guide 23 with the working cylinder 19 is displaced along the cross member 15 into the corresponding position. This setting (positioning) can also be made simultaneously and automatically with other format settings. If it is necessary to change the sheet stack 4, the non-stop roller blind 5 is retracted and at the same time the working cylinders 19; 19.1 controlled. The working cylinder 19.1 moves the alignment plate 20 from the parking position A against the rear edge 27 and the working cylinder 19 the corner holder 25 against the corner of the sheet 28 from the front edge 26 and the side edge 29.
  • the alignment plate 20 and corner holder 25 are now in the working position B.
  • the corner holder 25 is controlled in such a way that it stops at a minimal distance in front of the sheet corner 28; the alignment plate 20 is moved until it abuts the stacking surface of the rear edge 27. If the corner holder 25 and the alignment plate 20 have assumed their working position B, the sheet stack 4 is lowered. The sheets 3 floating on the sheet stack 4 and lying on top are guided and held in an exact position along the fixed corner holders 25 and the fixed alignment plates 20 until the stacking plate 10 is placed on the floor level or taxiway. At the same time, the sheets 3 above have settled and are now part of the sheet stack 4.
  • corner holders 25 and alignment plate 20 are moved through the working cylinders 19; 19.1 controlled in the parking position A and the sheet stack 4 moved out of the sheet delivery. After a new pallet 13 has been moved into the sheet delivery and the pallet 13 has been raised under the non-stop roller blind 5, the non-stop roller blind 5 is extended and the stacking starts again.
