  • the sheet feeder 2 is shown in a view from above.
  • a sheet table 20 adjoins the sheet feeder 2 in the sheet travel direction indicated by arrows, via which the sheet stream generated by the separation is transported to the sheet processing machine, for example the printing press 1.
  • the position of the sheet separation device 4 in association with the rear edge of the sheet stack S can be seen.
  • the orientation of the remaining stacking bars 7 is shown in their arrangement in relation to the sheet feeder 2, only the two outer remaining stacking bars 7 being shown and the others being indicated with lines of action.
  • the position shown is the waiting position outside the operating area of the sheet feeder 2.
  • the remaining stack bars 7 are guided within the remaining stack support device 3 so that they assume a horizontal position.
  • the rest of the stack support device 3 with its frame 6 is guided in the sheet feeder 2 by means of the guide rails 8 and vertically movable.
  • the residual pile hoist 5 is located on the upper side of the guide rails 8, engages from there on the frame 6 of the residual pile support device 3 and moves it up and down on the guide rails 8.
  • the residual stack support device 3 can be attached directly to the sheet feeder 2 by means of the guide rails 8 and raised over the entire height of the sheet separating device 4.
  • the residual pile hoist 5 is during the supply of a sheet processing machine, e.g. of the printing press 1, can be raised and lowered with a sheet, and the remaining stack support device 3 can be moved outside the processing area for the actual stack change.
  • This arrangement in the sheet feeder 2 makes it very easily accessible from its front operating side.
  • FIG. 3 shows a complete representation of the residual stack support device 3.
  • the frame 6 is guided vertically on the guide rails 8.
  • the rest of the stacking rods 7 in the form of supporting rods 7A and spacing rods 7B are guided in the frame 6 in a front support rail 9.
  • a traction drive 11 for occasionally pulling the support rods 7A and spacer rods 7B is arranged on a rear mounting rail 10.
  • the position shown is the waiting position.
  • drives 12 are provided on both sides for the longitudinal displacement of the rear support rail 10 on guide rails 13 on the frame 6.
  • the drives 12 determine the position of the rear mounting rail 10 at the rear end or within the frame 6.
  • the front mounting rail 9 is firmly connected to the frame 6.
  • the support rods 7A or spacer rods 7B are of different heights.
  • the support rods 7A are, for example, approximately twice as high as the spacer rods 7B.
  • the term height means the expansion of the support rods 7A or spacer rods 7B perpendicular to the plane of extent of the residual stack support device 3. The effect of this measure is shown in detail in the following diagrams.
  • the support rods 7A and spacer rods 7B can be of the same length. In a preferred embodiment, the support rods 7A are longer than the spacer rods 7B.
  • the support rods 7A are used to take over a remaining stack H first of the load suspension and are to be dimensioned accordingly, the load being diverted into another suspension element (see FIG. 4).
  • the residual stack support device 3 is shown in operation in FIG.
  • the support rods 7A and the spacer rods 7B are advanced by means of the drives 12 together with the rear support rail 10 relative to the front support rail 9 and inserted into grooves of a pallet P carrying the sheet stack S.
  • Front support rail 9 and rear support rail 10 with the traction drive 11 are now parallel in front of the pallet P, which carries a rest of a sheet stack S, the so-called residual stack H.
  • the pallet P and the remaining stack H are not touched by the front support rail 9.
  • the longer and higher support rods 7A rest on a residual stack lifting rail 14 at the front end in the sheet feeder 2, as seen in the direction of sheet travel.
  • This residual stack lifting rail 14 is coupled to a lifting drive and is provided for supporting the supporting rods 7A and their lifting movement during production.
  • the remaining stack lifting rail 14 and the remaining stack lifting mechanism 5 are both connected to the stack lifting device of the sheet feeder 2 or at least mechanically or control-technically coupled with one another in such a way that they can be lifted synchronously during the batch processing, but especially when the remaining stack H is brought together with a new sheet stack S.
  • the stack change thus proceeds as follows: I. - When a minimum height of the sheet stack S is reached, the stack change process is started. II. - The support rods 7A and the spacer rods 7B are together from
  • Support rods 7A the drawing process of the support rods 7A is initiated. VIII. - The support rods 7A are pulled out individually or in pairs from the inside to the outside between the remaining stack H and the stack of sheets S.
  • the spacer bars 7B are continuously between the inside and outside
  • the design of the device for pulling the remaining stacking rods 7 is oriented towards their special functions.
  • the remaining stacking bars 7 are shown here as differently shaped support bars 7A and spacer bars 7B and are located in the front mounting rail 9 and the rear mounting rail 10. Die
  • Support rods 7A are longer and about twice as thick as the spacer rods 7B. All remaining stack bars 7 are provided with a drive connection. For this purpose, the remaining stacking rods 7 are guided together on the rear mounting rail 10, on which individual drives 50 are arranged. At the rear end of the frame 6, a support rail 15 can be provided, which is not firmly connected to the remaining stacking bars 7, but can be moved both together with them and independently of them.
  • the final insertion movement up to the inserted end position can then be carried out via the rear mounting rail 10 from the drive 12 via the remaining path to the front mounting rail 9.
  • the rear mounting rail 10 can be moved on guide rails 13 by a drive 12 (see also FIGS. 3 and 4).
  • the drive 12 can be designed as a pressure medium drive or an electric motor drive.
  • An individual drive 50 is formed from a servo motor 52, a drive pinion 53 and a straight guide from a plurality of guide rollers 54.
  • the servo motor 52 sits vertically on the rear mounting rail 10 and extends through it.
  • the drive pinion 53 is arranged on the axis of the servo motor 52.
  • the drive pinion 53 engages in the toothing 51 on the
