Definitions

  • the invention relates to a device for dusting printed products with fine powder according to the preamble of claim 1.
  • Devices of this type are installed over the conveying path of the printed products on printing presses and dust the printed side of the freshly printed product with fine powder, so that the printed products do not stick together over the color layers when they are placed one on top of the other.
  • the fine powder particles of corn starch, CaCO3 or sugar have a particle size of usually between 10 and 50 microns and are atomized in an air stream. This mist is directed against the printed products via generally strip-shaped nozzle bodies, the axis of the strip bodies running parallel to the conveying direction of the printed products and a plurality of such nozzle bodies being arranged parallel to one another above the conveying path of the printed products.
  • the overall fog curtain produced by the nozzle body arrangement must be so wide that it still completely covers the widest printed products. If smaller printed products are printed, one must either accept that the part of the powder curtain that is located outside the printed products is uselessly generated and enters machine parts located below the path of the printed products. This is disadvantageous both in terms of the contamination of the machine and in terms of the cost of the powder material. If, on the other hand, you rebuild the nozzle body arrangement so that the width of the powder curtain corresponds to the width of the printed products, this means a longer stop of the printing press, which is only possible at very high Conditions is economically justifiable.
  • US Pat. No. 4,622,896 discloses a device for dusting printed products, in which a nozzle strip extending transversely to the conveying direction of the printed products has a plurality of nozzles attached at predetermined locations, each of which can be individually closed by snap-on annular caps. In this way, parts of the printed products that are not printed can be kept free from pollination. These caps are moved manually and under visual control, which is difficult for a pollinator housed inside a larger printing press.
  • the present invention therefore provides a device for dusting printed matter with fine powder according to the preamble of claim 1, in which the width of the powder curtain produced by the nozzle body arrangement can be changed at short notice and without complex adjustment work.
  • a pollination device In a pollination device according to claim 5, one can not only adjust different nozzle bodies strictly synchronously by the same distances, but also by different distances that are in a predetermined relationship to each other. Nevertheless, only a single mechanically moving drive rod is required, so that the mechanical structure of the pollination device is simple.
  • a pollination device In a pollination device according to claim 7, there is a finely adjustable soap adjustment of the nozzle body in conjunction with a very simple mechanical construction of the switching couplings which control the adjustment movement of the individual nozzle bodies.
  • a mechanically strictly coupled adjustment of the individual nozzle bodies is obtained in a mechanically particularly simple manner.
  • long strip-shaped nozzle bodies can also be placed at an angle to the conveying direction of the printed products.
  • Each of the nozzle bodies then sweeps over a transverse area of the printed products, which corresponds to the opening angle of the partial curtain produced by it plus the transverse offset of its ends.
  • the width of the powder mist generated by the individual nozzle bodies is automatically adjusted to the respective spacing of the nozzle bodies.
  • the powder dusting device shown in FIGS. 1 and 2 has two substantially U-shaped bearing frames 10, 12, each of which has a fastening plate 14 and lateral bearing legs 16, 18.
  • bores 20 are provided, in which mounting screws can be accommodated, which serve to attach the bearing frames 10, 12 to horizontal struts of a printing press or to attach the bearing frames 10, 12 to a support plate, not shown in the drawing, which then in turn is attached to a printing press.
  • a square guide rail 22 is fixed in the lower section in the bearing legs 16, 18.
  • a threaded spindle 26 is mounted parallel to the guide rail 22 in the bearing legs 16, 18 using axial / radial bearings 24.
  • This has a square drive section 28 which is mechanically coupled to an electric motor 30.
  • the left ends of the threaded spindles 26 carry chain wheels 32, over which a chain 34 runs.
  • the threaded spindle 26 of the rear bearing frame 12 which is not connected to a motor, is coupled to the driven threaded spindle 26 of the front bearing frame 10.
  • the guide heads 36 are slidable.
  • the guide heads 36 each have on the underside a T-shaped cross section running perpendicular to the drawing plane of FIG. 1 and having a complementary cross section with a rotationally symmetrical holding pin 40 which can be displaced and rotated and which moves from the top of an assigned nozzle strip, indicated overall by 42 is at the top.
  • the nozzle strips 42 each have an internal distribution channel 44 which runs in the longitudinal direction of the strip and which, via a plurality of dispensing nozzles pointing downward, emits a powder mist against printed products which pass under the nozzle strip arrangement.
  • the guide heads 36 In its upper section, the guide heads 36 have a threaded bore 48 into which a locking screw 50 can be screwed, the tip of which works into the top of the guide rail 22. Of the various guide heads 36, only one is equipped with a locking screw 50; in the embodiment shown in FIG. 1, this is the middle guide head. This selected guide head serves as a fixed point when the nozzle bar 42 is adjusted in the transverse direction.
  • a parallelogram scissor grille designated overall by 52, which has grating arms 54, 56 laid crosswise.
  • the lattice links 54, 56 are each articulated to one of the guide heads 36 at the crossover point by means of a pivot pin 58.
  • the free ends of the lattice links 54, 56 are connected by pivot pins 60, 62.
  • One of the guide heads 36 which differs from the guide head 36 braked by the locking screw 50, in the exemplary embodiment shown in FIG. 1 the leftmost of the guide heads 36, carries a drive head 64 which is provided with a threaded bore 66 which is on the threaded spindle 26 is running.
  • the distance between the nozzle strips 42 can thus be increased or decreased, the adjustment movement taking place symmetrically to the braked central guide head and thus also the central nozzle strip.
  • the rightmost guide head in Fig. 1 were braked, one would get a constant increase or decrease in the spacing between the nozzle strips, based on a fixed point, which is the same as in Fig. 1 and 2, if the powder dusting device shown in Figs Figure 1 is the right end of the guide rail 22.
  • the distributor channels 44 of the various nozzle strips 42 are connected to a mist generator (not shown in more detail) via flexible hoses 68.
  • the powder mist is obtained by atomizing fine particles of 10 to 50 microns, preferably 15 to 20 microns from corn starch, CaCO3 or sugar in a stream of compressed air.
  • the powder dusting device shown in FIGS. 1 and 2 can be adjusted simply by exciting the electric motor 30 in one or the other sense of rotation for the dusting of printed products of different widths.
  • the printed products of different widths can either be fed to the center of the printing machine (central guide head braked) or fed in that their one side edges run equally on one side of the printing press (edge guide head braked).
  • the threaded spindle 26 now has two spindle sections 26a and 26b provided with opposite threads, which work together with two drive heads 64 which are placed on the two peripheral guide heads 36. These peripheral guide heads are thus inevitably moved symmetrically to the center plane of the powdering device.
  • helical springs 70 are now provided, each of which is inserted between adjacent guide heads 36 arranged on the guide rail 22 with slight sliding play.
  • the coupling chain 34 provided in the exemplary embodiment according to FIGS. 1 and 2 is also omitted.
  • the drive sections 28 of both threaded spindles 26 are each connected to an associated electric motor 30 or 30 ', so that the distance between the guide heads and nozzle strips for the front and rear bearing frames can be set differently. It is also possible to achieve an inclined position of the nozzle strips 42 with respect to the conveying direction of the printed products (from top to bottom in FIG. 4), as shown in FIG. 4.
  • Each of the nozzle strips 42 can thus sweep over a transverse area of the printed products which is larger than the cone opening angle of the corresponds to fog generated by the individual nozzle strip 42.
  • each of the guide heads 36 is assigned its own drive head 64 which runs on the threaded spindle 26.
  • the drive heads 64 contain specially designed clutches, by means of which they can optionally be connected to the threaded spindle 26 in a drive-locking manner or can be separated therefrom.

  • the width of the powder mist generated overall by the nozzle bar arrangement can thus either be set automatically in accordance with the width of the printed products measured by the multiple light barrier 80 or selected in accordance with values set on the keypad 76.
