Definitions

  • the invention relates to a device for releasing plates from a cylinder of a rotary printing press according to the preamble of claim 1.
  • a plate cylinder with a device for lifting a printing plate has become known.
  • the plate cylinder below the pressure plate has bores that can be pressurized with air for lifting the pressure plate.
  • a disadvantage of this plate cylinder is that complex pressure feeds are necessary.
  • the invention has for its object to provide a device for releasing plates with bent ends from a cylinder of a rotary printing press, with which at least one bent end of the plate can be detached from the cylinder.
  • the advantages that can be achieved with the invention are, in particular, that the detachment of a folded end of the plate from the surface of the latent raster using a known simple clamping device.
  • the known clamping device consists of a pivotable spindle which has hooks or projections according to the invention on its periphery on the trailing end of the plate.
  • the released from the surface of the plate cylinder due to rotation of the spindle end of the plate can thus without further aids, for. B. removed from the axial slot of the cylinder.
  • no parts are arranged outside the cylinder or do not protrude beyond the outer surface of the cylinder.
  • the hooks of the device according to the invention move within the slot receiving the ends of the plate or in a groove of the spindle.
  • Fig. 1 is a schematic representation of a
  • FIG. 2 shows a detail "Z" according to FIG. 1 with an enlarged illustration of a hook in clamping position
  • Fig. 3 is a corresponding representation of Figure 2 with a hook in Lenderposit on.
  • Fig. 4 is a view A of Figure 2 on a hook bar, but without showing the bent leg of the plate.
  • Fig. 5 is a view H of FIG. 2 in a further embodiment.
  • z. B. d2 0.2 to 0.3 mm
  • it is preferably printing plates or carrier plates with z. B. attached rubber blankets 9.
  • a leg 11 of the leading end 3 is longer in the present example than a corresponding leg 12 of the trailing end 4 of the P plate 2.
  • the slot 8 is preferably rectangular in cross section.
  • the slot 8 opens into a recess 16 running parallel to the slot 8.
  • the recess 16 has the shape of a bore 16.
  • the bore 16 is connected to the slot 8.
  • a lever 18 or holder 18 or spindle 18 Arranged in this bore 16 is a lever 18 or holder 18 or spindle 18 which can be pivoted about its longitudinal axis 17. In the present exemplary embodiment, a spindle 18 provided with a known drive is used.
  • This spindle 18 has on its periphery 19 a in the axial and radial direction (or along a secant) of the spindle 18 extending groove 23 with z. B. rectangular cross-section.
  • this groove 23 there is at least one single plate-width bar 22 or several short bars 22 per Plate width arranged.
  • These are shown 22 are adapted in the middle and lower part of their cross section of the groove 23 so that they can be moved radially in it and have on their side facing the slot 8 one or more extending in the axially parallel direction , spaced apart axially elongated projections 21 or hooks 21.
  • These hooks 21 have a length c of z. B. 60 mm or 10 mm at a distance e of z. B. 10 mm vone i nande r.
  • each compression spring 27 is supported on the bottom of the blind hole 26, its force application point acts in the radial or parallel direction of the spindle 18 against the near-bottom bottom 28 of the ejection lever 22.
  • the projections 21 become during the clamping position of the plate 2 at least its front edge 29 against the legs 12 inserted into the slot 8; 11 pressed, whereby the legs 11; 12 against the cylinder 1 are set (Fig. 1 and 2).
  • the spindle 18 is moved in the direction of the ends of the bent legs 11; 12, e.g. B. counterclockwise ge rdre direction until the End face 15 of the projections 21 as a result of the spring action engage in recesses 31 located at the end of the leg 12 of the trailing end 4 with the end face 10 or engage on the end face 5 at the end 20, 34 of the trailing leg 12.
  • Each projection 21 is assigned, for example a right-hand kf örmi ge, recess 31 in the leg end 20, 34 when the plate end is perforated.
  • the projections 21 with the push-out surfaces 15 each engage behind an upper edge 32 with the end face 10 of the recesses 31 or the end 20, 34 with the end face 5 of the shortened leg 12.
  • the Ausschi ebe le i st e 22 can be moved by the spring force in the radial direction of the groove 23 until it abuts part of its periphery 33 against a spi nd it stop 36 in the groove 23.
  • the projections 21 of the viewing lever 22 can - viewed in the axial direction - be continuous or spaced apart.
  • the cross section of the clamping pieces G can be any, for. B. rectangular, circular, right ec k-rundste rni g or in the form of a step enha Lbsche be etc.
  • the number of cutouts is 22 with hooks 21 less than the number of clamping pieces G, e.g. B. one to two to one to four. From schi ebe le ist ten 22 and clamping pieces G can be the same length, z. B. of 60 mm sen.
  • hooks 21 provided with hooks 22 engage behind the end 20, 34 on the end face 5 of a shortened leg 12. Corresponding recesses 31 in the leg 12 associated with the hooks or projections 21 are then omitted.
  • the projections 21 are z. B. in the upper part inside the groove 23 the stops 36 attached. They are adapted in their contour to the contour of the hooks 21 or the clamping pieces G. They should form a radial movement limitation of the hooks 21 or clamping pieces G in the direction of the insertion slot 8.
  • the upper part of the pull-out bar 22 with projections or hooks 21 has, in the embodiment, a cross-section of a stepped shape.
  • Beta angle of rotation (18)

Abstract

L'invention concerne un dispositif pour enlever des plaques fixées à un cylindre d'une presse rotative à imprimer devant permettre d'enlever une extrémité pliée (3, 4) du cylindre (1) par des moyens techniques simples. Pour ce faire, une broche (18) montée dans le cylindre (1) de manière à pouvoir pivoter possède sur sa circonférence des protubérances (21) juxtaposées dans le sens axial et agissant de façon élastique dans le sens radial, sur l'extrémité suivante de la plaque (9).
