Definitions

  • the invention relates to a sheet delivery device on printing machines according to the preamble of claim 1.
  • the braking effect on the end of the sheet to be discharged and deposited is achieved by a lower peripheral speed of the brake rollers compared to the higher rotating speed of the chain conveyor corresponding to the machine speed.
  • the risk of smearing results in the need to use the brake rollers only in the often very narrow, pressure-free arc areas. They are therefore usually laterally adjustable on their support elements and may also be the entire braking devices - or at least the bow-carrying parts thereof - are interchangeable with those with a differently designed bow support surface and suction. A change in the non-printing zones in the printed image and the choice of a different paper type can thus be taken into account immediately.
  • the present invention is based on the object of developing a generic sheet delivery device on printing presses in such a way that in particular their advantages in terms of interchangeability and flexibility are retained, but at the same time certain disadvantages are eliminated.
  • braking devices are to be created which are particularly suitable for front and back printing, i.e. above all have narrow, but effective, arch-bearing surfaces, as well as a wide range of settings for air adjustment; and ultimately the influence of wear-resistant brake roller rings should be reduced or their use should become absolutely unnecessary.
  • This device is not suitable for use in printing machines for perfecting and printing alone, if only because of the risk of smearing.
  • a device with a similar effect is also known from DE-GM 17 93 746.
  • the suction roller described therein is also not suitable for perfecting. Their disadvantages lie, in particular, in the width of the arc-bearing circumferential surface, which can only be reduced to a limited extent due to the structural design, and in the negative influence of the effect and adjustability of the suction air by the incorporated channels.
  • a carrier shaft 4 is fastened in front of a delivery stack 1 of a sheet delivery in the side walls 2 and 3 thereof and serves to hold absorbent bodies 5 to be described in more detail later.
  • a number of brake rollers 8 are provided on a drive shaft 6 which is mounted in the side walls 2 and 3 and is connected to a drive motor 7. These are driven via the drive shaft 6 at a circumferential speed which is reduced compared to the machine speed, a number of braking devices being arranged on their support devices 4, 6 at arbitrary intervals and a sheet 9 to be laid out (FIG. 2) which is fed to the delivery stack 1, slow down and tighten.
  • Figure 2 shows a side view of such a braking device according to the invention, essentially in two parts.
  • Chain grippers 11 arranged on a transport chain 10 at certain intervals transport the freshly printed sheet 9 out of the machine to the delivery stack 1. Shortly before this delivery stack 1 graze the individual sheet 9 over the braking devices, the circumferential surface of each brake roller 8 forming the sheet-bearing region.
  • the brake roller 8 is designed as a disk and, in the exemplary embodiment according to FIGS. 2 to 4, has on its entire flat circumferential surface 50 in the lateral recesses 12 extending into one end face 17. On the same end face 17 there is also a journal 13 which supports the mounting of the brake roller 8 on the drive shaft 6 and the receptacle, i.e. Support of the absorbent body 5 is used.
  • the positive drive connection is established via a longitudinal groove 14 of the drive shaft 6 and a driving screw 15 cooperating therewith in the journal 13, and furthermore a lateral displacement and locking of the brake roller 8 in any position is possible.
  • the bearing clamp 18 On the carrier shaft 4, the suction body 5 attached to it is supported by a bearing clamp 18.
  • the bearing clamp 18 has a tab 19 in its lower region, a locking screw 21 engaging in a thread 20 incorporated therein, so that the entire suction body 5 can be moved along the carrier shaft 4 and locked at any point, just like the brake roller 8 .
  • the tab 19 is only loosely in two holes 22 of the L agerschelle inserted 18 and the set screw 21 may be removed at any time, so that thereafter, the entire absorbent body 5 can be lifted from the cross member 4 after release.
  • a simple disassembly of the brake rollers 8 is possible due to the special design of the drive shaft 6, as shown in FIG. 1.
  • the drive shaft 6 divided in two and a short drive shaft part 6.1 is provided, which is fitted by means of shaft journal 24 and pin 25 into a bore 26 of the drive shaft 6 and connected to it.
  • the short drive shaft part 6.1. pulled out of its storage on the side wall 3 by means of a handle 16, so that afterwards the individual brake rollers 8, after previously removing or pivoting the suction body 5, can be successively withdrawn through the free space now created between the drive shaft 6 and side wall 3 and, for example, exchanged for other brake rollers .
  • the suction body 5 arranged on the carrier shaft 4 by means of the bearing clamp 18 initially consists of a suction air connection 28 which opens into a part 29 of the suction body 5 which is connected to the bearing clamp 18 (for example a welded connection) and which is provided with corresponding bores 30, 31 for the purpose of forwarding the suction air .
  • An elongated channel body 32 with a cavity 54 is connected to this part 29, the front area 33 of which rests on the bearing journal 13 of the brake roller 8.
  • the channel body 32 Against the end face 17 of the brake roller 8 provided with the recesses 12, the channel body 32 has an elongated hole 35 which opens into a segment plate 36, likewise provided with a corresponding elongated hole 55, which, as shown in particular in FIG.
  • suction air whose path through the individual elements of the suction body 5 is shown in FIG. 3 by means of corresponding arrows ⁇ , can act on the arc 9 and due to the lateral recesses 12, a corresponding lateral suction air removal also take place.
  • the indirect contact of the channel body 32 on the brake roller 8 or the sealing effect of the interposed segment plate 36 can be supported, for example, by a leaf spring 39, which is fastened to part 29 via plate 40 and fastening screws 41 and acts as a counterforce (reaction force) the channel body 32 presses against the brake roller 8 via the segment plate 36.
  • FIGS. 5 to 9 show further possible embodiments of the braking devices according to the invention.
  • a further reduction in the area of the sheet-carrying area is achieved by a brake roller 42 provided with a shoulder 51 on the outer circumference.
  • the other structure of this embodiment variant corresponds to the exemplary embodiment described in greater detail in accordance with FIGS. 2 to 4.
  • FIG. 6 shows a brake roller 43 with a symmetrically curved circumferential surface 48 with respect to the center line 27 thereof, the sheet 9 being carried by a suction roller ring 44 attached. This is supported on webs 52 remaining between the recesses 12.
  • the brake roller 45 has recesses 12 on both sides, and consequently the two end faces 17, 38 are also designed in a corresponding manner and, in terms of their construction, those channel bodies 32 which are attached to part 29 and which are corresponding to the embodiment according to FIGS. 2 to 4, and segment plates 36 and journal 13 are assigned.
  • the arc-bearing circumferential surface 49 of the brake roller 45 is chamfered symmetrically with respect to the center line 27, as a result of which the arc-bearing region can in turn be kept very narrow.
  • the two channel bodies 32 could also be supplied with suction air independently of one another, which expands the metering options.
  • FIGS. 8 and 9 also shows the suction body 5 assigned to the brake roller 46 on both sides.
  • the essential modification compared to the aforementioned embodiments is that the brake roller 46 has a quasi sprocket-like shape (FIG. 9).
  • the arch-bearing surface is in turn formed by a suction roller ring 44, which is supported on the sprocket webs 47, which are regularly distributed over the circumference.
  • the circumferential surface of the brake roller used in each case can have both a flattened shape and an oblique or more or less strongly curved shape, and can be provided with a suction roller ring (44). If no suction roller ring 44 is used, the extent of the curvature or bevel determines in particular the width of the area carrying the sheet.
  • the invention therefore naturally also includes embodiments and combinations which, although not shown or described above, can be derived directly from them.
