Definitions

  • the invention relates to a transfer drum for perfecting machines with two sheet support surfaces, each of which is formed by two interlocking sheet carrier combs, one sheet carrier comb having a device for detecting the leading edge of the sheet and at least one of the two interlocking sheet carrier combs being adjustable relative to the other about the axis of rotation of the transfer drum .
  • the invention provides a remedy here.
  • a device is to be provided on the transfer drum of a perfecting machine, by means of which, after the printing of the machine, duplication phenomena which can be attributed to concentricity or shape errors of the transfer drum can be eliminated.
  • this object is achieved in that parts of the arch wings or the arch wings as a whole are radially adjustable. This not only makes it possible to compensate for radial runout and form errors, but also for later changes to the adjustable parts of the transfer drum.
  • a particularly advantageous embodiment of the invention consisting of a basic drum body with arch supports and the device for grasping the leading edge of the drum, and a hollow body with arch supports partially encompassing the basic drum body and a device for grasping the trailing edge of the bow, provides that the hollow body is provided on the basic drum body two cylinder journals are mounted on a slide ring, that play is provided between the cylinder journal and the slide ring and that adjusting screws are arranged in the hollow body, which act on the slide ring and locally eliminate the play between the inner surface of the slide ring and the cylinder journal running surface or adjust the arc carrier radially len.
  • This embodiment of the invention not only permits the radial adjustment of the entire arch support surfaces, but also enables the adjustable hollow body to be adjusted and aligned in a very simple manner during the initial assembly or during subsequent repair assemblies without play.
  • a further advantageous embodiment of the invention relates to a transfer drum with a sheet carrier comb composed of individual sheet support segments, at one end of which the device for detecting the leading edge of the sheet is provided, and with a further sheet carrier comb likewise formed from individual sheet support segments, at one end of which a device for detecting the The trailing edge of the arch is arranged, all of the arch support segments being mounted on a common axis.
  • some or all of the arch support segments are mounted on the axle via a slide ring, play being provided between the inner surface of the slide ring and the axle and furthermore adjusting screws are arranged in the arc support segments provided with a slide ring, which act on and through the slide ring Deforming the slide ring Eliminate the clearance between the inner surface of the slide ring and the axle locally or adjust the arch support segments radially.
  • inventive measures here also offer the possibility of adjusting the individual arch support segments to one another in a simple manner.
  • the two mentioned embodiments of the invention can also experience such a modification that, with the elimination of the slide rings, the set screws act directly on the cylinder running surface or on the axle.
  • certain surface parts of the arch support surfaces e.g. B. in the form of rails, adjusting bolts or blocks adjustable in height.
  • the transfer drum according to FIGS. 1 and 2 essentially consists of two main parts, namely the drum base body 1 and the hollow body 2.
  • the drum base body 1 is firmly attached to the axis 3, on the free cylinder journal 4 and 5 of which the hollow body 2 has a sliding ring 6 is rotatably mounted.
  • the drum base body 1 is provided with two diametrically opposed sheet carrier combs 7, each of which is equipped on one side with comb carriers 8 arranged in the manner of a comb and on its other side with a device 9 for detecting the leading edge of the sheet.
  • the hollow body 2 is provided in the same way with diametrically opposed arch support combs 10 which have arch supports 11 on the side facing the adjacent arch support comb 7, which are arranged like a comb and on their other side carry a device 12 for detecting the trailing edge of the arch.
  • the slide rings 6 already mentioned are attached by means of a press fit; in addition, four adjusting screws 14, which act on the slide ring 6, are screwed into each bearing hub 13 evenly distributed over the circumference.
  • an arch support comb 7 and an arch support comb 10 together form an arch support surface 15.
  • They can be arranged offset with respect to one another ten arch supports 8 and 11 are pushed into one another or into their outer position according to FIG. 1.
  • the position of the arch carrier combs 7 and 10 shown in FIG. 1 corresponds to the largest arch format.
  • Figures 3, 4 and 5 show the special arrangement of the bearing of the hollow body 2.
  • the slide ring 6 is fastened in the bearing hub 13 by means of a tight fit.
  • a clearance 18 of 0.05 mm, for example, is provided between the inner surface 16 of the slide ring and the running surface 17 of the cylinder pins 4 and 5, respectively.
  • the transfer drum is installed in the perfecting machine.
  • FIG. 5 shows the corresponding setting of the adjusting screws 14 and the slide ring 6.
  • the hollow body 2 could also have the same game 18 can be shifted eccentrically using the upper and lower set screws.
  • the adjustment of the arch carrier combs 10 of the hollow body 2 is sufficient to completely eliminate the rhythmic duplication phenomena that have occurred.
  • Figures 6 and 7 show a transfer drum with two arch support surfaces 15, in which two groups of arch support segments 20 and 21 are threaded on the axis, in such a way that the arch support segments 20 and 21 alternate.
  • the arch support segments 20 are firmly attached to the axis 3 and are combined to form arch support combs 7 by means of diametrically opposite devices 9 for detecting the front edge of the arch.
  • the other arch support segments 21 are likewise connected to one another, specifically by means 12 for detecting the trailing edge of the arch.
  • the arch support segments 21 thus form the two diametrically opposite arch support combs 10.
  • the bearing hubs 13 of these arch support segments 21 have the previously mentioned set screws 14 symmetrical to the circumference.
  • the design of the bearing of all four arch support segments 21 equipped with set screws 14 corresponds entirely to that shown in FIGS. 3, 4 and 5.
  • the four arch support segments 21 provided with set screws 14 can therefore be adjusted radially if required. Since the remaining arch support segments 21 are supported with a certain play and are connected to one another overall via the device 12 for detecting the trailing edge of the arch, the adjustment has an effect on the entire arch support comb 10.
  • the sheet transfer drum shown in FIG. 8 with two sheet support surfaces 15 is similar in structure to that shown in FIGS. 1 and 2.
  • a drum base body 1 is fixed on the axis 3, while the hollow body 2 is mounted so as to be adjustable about the axis 3.
  • the compensation of a possible concentricity or shape error is not, however, carried out by adjustment measures on the mounting of the hollow body 2, but parts of the arch support surface 15 itself are designed to be radially adjustable.
  • the two devices 12 for grasping the trailing edge of the arch have radially adjustable adjusting blocks 22 in front of them.
  • the sheet guiding surface 23 of the blocks 22 is at the same height as the sheet support 15. However, if a runout error is found in the imprint, this can be remedied by placing one of the blocks 22 radially in this way is adjusted so that its sheet guiding surface 23 is higher than the sheet support surface 15. By such a simple measure, the incorrect position of the print end can be corrected with low concentricity errors.
  • FIG. 9 also shows a basic structure of the transfer drum, as has already been described with reference to FIGS. 1 and 2.
  • 15 adjustment options are provided neither on the two bearings of the hollow body 2 nor in its arch support surface.
  • a set screw 24 is screwed into the arch carrier combs 10 at the level of each arch carrier 11 in such a way that its free end 25 abuts against a stop 26 which is provided at the end of the arch carrier 11 on the inner edge 27 thereof.
  • the invention offers the possibility of eliminating even the smallest manufacturing inaccuracies which could still have a negative effect on the printed image.
