Definitions

  • the invention relates to a device on sheet-fed printing machines for the lubrication-free feeding of sheets printed in particular on both sides through the machine by means of laterally adjustable sheet guiding means.
  • the printing sheets are held and guided in their conveying path with different sheet guides in order to transport the printing sheets safely and flutter-free through the printing machine during their sheet travel.
  • the sheet processing machine would have to be shut down.
  • the sheet guides in the machine were arranged almost unavailable to the editing staff, so that at least two workers had to work together on call to adjust the sheet guides according to the prevailing conditions of the printed images on the printed sheet in order to avoid smearing of the printed sheets .
  • a test run of the machine had to be carried out and the effect of the respective adjustment had to be observed. Depending on whether the result was positive or negative, the latter had to be readjusted with the sheet-processing machine turned off.
  • Sheet guide device for sheet guide cylinders in multicolor sheet-fed rotary printing machines disclosed. To avoid smearing the freshly printed area below the printing cylinder and the sheet guiding cylinder, this has a number of hollow sheet guide bars with air outlet openings.
  • the sheet guiding devices in the form of holding disks are arranged axially displaceably on the sheet guide cylinder. This means that the sheet guiding devices can be arranged at locations where there is no ink application on the sheet. The task was to guide the sheet end in a fitting manner when the sheet was already released at its front edge, taking into account the format adjustment during production and intermittent operation.
  • the inaccessibility mostly meant that the personnel were forced to get into or under the sheet-guiding machine in order to be able to carry out the adjustment process. For the above-mentioned difficult reasons, it was usually necessary to correct them consecutively. This led to great loss of time on the sheet-processing machines.
  • the invention is based on the object of being able to adjust sheet guiding means laterally in a time-saving manner by an operator to the free spaces between printed images.
  • the sheet guiding means are laterally remotely adjustable by motor or by hand while the machine is running from the sheet processing machine or from an evaluation table by means of a central adjustment, and in that the position of the sheet guiding means is in direct comparison to Ink order can be displayed.
  • the adjustment can be carried out by an operator without direct visibility and access to the sheet guiding means. There is no time-consuming stopping of the machine. There is no need to check when the machine is restarted, which means that a large amount of waste is eliminated.
  • the rod-shaped sheet guides are attached as a sheet guide holder with a drive block.
  • the drive block with the bow guide rod sits on a cross member designed as a drive element or guide element.
  • the drive block can e.g. B. be provided with a gear and a motor or with a connection for appropriate traction or pressure. Hydraulic or pneumatic adjustment means can also be provided.
  • the drives can be controlled from any position outside the machine.
  • a scale bar with z. B. LEDs or other display means are provided, after which the operating personnel can make the setting for the plate cylinder.
  • the setting can be made on each individual machine tower or from the control table. In the case of multi-color printing presses, however, the adjustment can be carried out directly in front of each plate cylinder or, in the case of two-sided printing, by a central adjustment for both plate cylinders.
  • the printed sheet is supplied as a reference and the printer can adjust the entire sheet guiding device in the machine using the light-emitting diode bar or the scale bar.
  • FIG. 1 shows a printed sheet 2, which is arranged on a plate cylinder 7, within a sheet processing machine 1, not shown in detail.
  • Sheet guiding means 4, 4, 1 are positioned in the pressure-free zones of the sheet 2.
  • Individual light-emitting diodes of a light-emitting diode display 12 light up on a reference bar 11 at the position of the sheet guiding means 4, 4.1.
  • the reference bar 11 can also have a scale bar 12.3.
  • the reference strip 11 can, as shown here, be arranged directly on the plate cylinder 7, or a further display can be arranged on the evaluation table of the printed printing sheet 2, so that the printer can adjust the sheet guiding means 4, 4, 1 from there while the machine is running. This has the advantage that an immediate check on the machine's system on the printed sheet is visible.
  • a central adjustment 8 is actuated by the operating personnel to adjust the sheet guiding means 4, 4.1.
  • the central adjustment 8 is connected to the drive blocks 10 via a feed line 14. From here, they can be called up individually for each adjustment process at the push of a button.
  • the drive blocks 10 of the sheet guiding means 4, 4.1 are in turn guided on a traverse 9.
  • a toothed rack 16 for the adjustment of the sheet guiding means 4, 4.1 is attached to the crossmember 9.
  • a digital display 13 on the central adjustment 8 additionally enables, in addition to the light-emitting diode displays 12 and the scale strip 12.1, a control during the adjustment process of the sheet guiding means 4, 4.1.
  • the individual sheet guiding means 4, 4. 1 can be displayed on this digital display 13 and can accordingly be called up on the central adjustment 8 and adjusted by pressing a button.
  • the sheet guiding means 4 is shown in section. This is composed of the drive block 10 and an electric motor 15.
  • a drive pinion 15.1 is arranged on the motor 15 and acts on a toothed rack 16 of the crossmember 9.
  • the drive block 10 is held and guided on the crossmember 9 by means of two roller guides 17.
  • the electrical control of the motor 15 takes place via a feed line 14.
  • the sheet guide rod is welded to a web-like holder 4.2 on the drive block 10.
  • the sheet guide rod of the sheet guide means 4 is curved in accordance with the sheet guide path.
  • a similar adjustment by means of the motor 15 can, for example, except on the sheet guiding means 4, 4.1. B. individually and mutually adjustable on sheet guide wheels and other sheet guide means within the sheet processing machine 1.
  • FIG. 3 shows a further possibility of adjusting sheet guiding means 3 in the form of a manually operated adjustment mechanism.
  • the sheet guiding means 3 is held in a drive block 10.1.
  • a Bowden cable 6 leads from the drive block 10.1 to a hand lever 5.
  • a special hand lever 5 is provided for each bow guiding means 3.
  • a flexible shaft can also be provided between the hand lever 5 and the drive block 10.1.
  • This version is much cheaper than the version with the drive motors.
  • the adjustment can be carried out just as easily, safely and quickly by an operator while the machine is running and it can be checked immediately after the adjustment whether individual images of the printed sheets still smear on the sheet guiding means 3 or not.
  • the reference strip 11 with the light-emitting diode display 12 is of particular importance and considerably simplifies the adjustment process for the sheet guiding means 3 for the operator.
  • the hand levers 5 are arranged in rows next to one another in accordance with the sheet guiding means 3 arranged in the sheet processing machine 1.
