Definitions

  • the invention relates to a device for holding the lower elevator of a two-layer elevator on the outer surface of a printing cylinder in printing machines according to the preamble of claim 1 (DE-A No. 1914373).
  • DE-A No. 1611325 has disclosed a device for holding a two-layer elevator on the printing cylinder of printing presses, in which the basic elevator is clamped between two rails.
  • the exact position of the clamping rails clamping the basic elevator is achieved by known heads of the cylinder screws projecting into bores at the edge of the pressure cylinder and located on the clamping rails, magnets being arranged in the bores for holding them.
  • the holding device should be designed to be extremely space-saving. In addition to the possibility of being able to fasten the lower elevator on the holding device, it should also be ensured that it is always positioned parallel to the axis and at a predetermined distance from the outer edge of the impression cylinder.
  • the pressure cylinder 1 shown in FIG. 1 has a recess 2 on its circumference, which essentially serves to accommodate the two tensioning devices 3 for the upper elevator 4.
  • the holding device 5 for the lower elevator 6 is arranged in the intermediate space formed by the upper elevator 4, its tensioning device 3 and by the edge 7 of the recess 2.
  • the lower elevator 6 itself does not extend over the entire circumference of the printing cylinder 1.
  • the holding device 5 shown in FIG. 2 mainly consists of a holding rail 8, which extends over the entire length of the printing cylinder 1, which essentially has a circular cross section and is provided with a secant flattening 9 for the support of the lower elevator 6.
  • the entire holding device 5 with the lower elevator 6 attached to it is through the prism-shaped gap 10, which between the edge 7 and the clamping device device 3 arises, positioned axially parallel and additionally pressed into this position by the tensioned upper elevator 4.
  • the connection between the lower elevator 6 and the holding device 5 takes place via the holding bolts 11 provided on the holding rail 8.
  • the shaft 12 of each holding bolt 11 projects through a corresponding bore in the holding rail 8 and can be rotated about its longitudinal axis.
  • the holding rail 8 is provided with a cutout 13 at the exit point of the holding bolt 11.
  • a plate spring 14, which abuts against a collar 15 provided at the shaft end of the retaining bolt 11, ensures that the retaining bolt head 16, which is cylindrical in cross section, abuts the secant flattening 9 of the retaining rail 8.
  • the upper head end 17 of the retaining bolt head 16 is round-headed in the selected exemplary embodiment Two-edged (FIG. 4), the essential general criterion for the function of the upper head end 17 being that it has a different length / width ratio in cross section.
  • the lower elevator 6 and the reinforcing rail 18 provided between the upper head end 17 of the retaining bolt 11 and the lower elevator 6 are provided with punched holes 19 machined in the predetermined positions, the cross-section of which corresponds to that of the upper head end 17.
  • the connection between the holding device 5 and the lower elevator 6 now takes place in such a way that the latter is guided over the upper head end 17 of the holding bolt 11 and brought to bear on the secant flat 9 of the holding rail 8.
  • the retaining bolt 11 is now turned through 90 °. which results in a positive locking connection.
  • the reinforcing rail 18 prevents the lower elevator 6 from tearing out at the clamping points. There is no need for the function of the device according to the invention for the reinforcing rail 18 to extend over the entire cylinder length or for the retaining bolts 11 to be distributed over the entire cylinder length.
  • connection between the pressure cylinder 1 and the holding device 5 is in each case on the end face.
  • a conical pin 20 protruding from the holding rail 8 is inserted into a centering hole 21 of the bearer ring 22 in this exemplary embodiment.
  • a further conical pin 23 provided on the opposite side of the holding rail 8 is inserted into a corresponding centering hole 21 of the other bearer ring 22, wherein it is supported on the holding rail 8 via a spring 24. It is essential that the dimension is defined from the one end face 25 of the holding rail 8, which is provided with the fixed conical pin 20, to the holding bolts 11, and this ensures that, together with the punched holes 19 likewise provided in a predetermined position, the lower elevator 6 is exact rests on the printing cylinder 1 at the desired location.
  • FIG. 5 A further embodiment of the holding rail 27 with its fastening at the end is shown in FIG. 5.
  • One end of the holding rail 27 is provided with a cone 28 which engages in the centering bore 21 of the one bearer ring 22.
  • the other end of the holding rail 27 is equipped with a pin 29, which in turn engages in a corresponding recess 30 of the other bearer ring 22.
  • said recess 30 can expediently be designed as a longitudinal groove running radially to the axis of the bearer ring 22.
  • a compression spring 32 arranged on the pin 29 and supported on the shoulder 31 and on the bearer ring 22 ensures the lateral positioning of the holding rail 27 as defined by the seat of the cone 28.
  • reinforcement rail 18 and lower elevator 6 are provided with punched holes 19, 33, as can be seen from FIG. 6.
  • the lower elevator 6 is guided over the upper head ends 17 of the retaining bolts 11 and brought to bear on the secant flattening 9 of the retaining rail 27. Then it is shifted laterally in such a way that the upper head end 17 overlaps the punched holes 19, 33, so that the clamp connection is established.
