Definitions

  • the invention relates to a printing material conveying device for printing units of printing presses, the Printing material conveying device a first printing unit is subordinate for accessibility of the first Printing unit has a displaceable section, a display and a transport device owns and the print material a finishing location feeds, and being the transport device at least one endless conveyor with pusher links for the printed matter.
  • a printing material conveying device of the type mentioned Art is known and is used for the printing unit the printing material leaving the printing press To supply processing location, in particular one another printing unit of a multicolour printing machine.
  • the printing material conveying device has one of several, parallel to each other at a distance Belts of existing endless belt conveyors on which the print material from the printing unit housing promotes.
  • At least one of the endless dreams of Transport device is as provided with thrust links Endless conveyor trained.
  • a print item for example a sheet of metal, which is the (first) printing unit leaves, is thus connected in series by means of the two Endless belt conveyors, one form the so-called display, the horizontal one Run of the transport device, wherein the shark fin-like thrust links of the chain having endless conveyor the rear edge of the Reach behind the sheet and in this way and Feed the print material to the following printing unit.
  • the shark fin-like thrust members of thrust rollers one Endless run of the transport device overhauled, which take over the rear edge of the metal sheet and the front edge of the board the contact marks of the printing cylinder of the subsequent printing unit at somewhat increased speed respectively.
  • the under spring tension standing thrust rollers cause an exact position of the Front edge of the board at the landing marks and dive after creating the sheet, according to the Deflection area of the associated endless run, from.
  • the one to the transport device leading endless belt conveyor known printing material conveying device is preferred formed in two parts, that is, it points a pivot axis between its two ends, such that - viewed from the operator's side - can assume a V-shaped position with the consequence that in the working position the printing unit Delivery end facing obliquely or vertically stands upwards, so that there is a release position results, that is, it becomes an "alley" in the Printed material conveying path formed, which is an accessibility to the printing unit.
  • the said Accessible endless belt conveyors a constructional, certain overall length and on the other hand the subsequent transport device also a certain one, through which co-determining the largest possible format of the printed material Can not be less than the overall length, this leads to a relatively large distance between each Printing units of a multicolour printing machine.
  • a four-color press which by means of an investor sheet of a stack and the one painting machine follows, there is an overall length of around 30 meters, that is, the well-known design needs correspondingly large installation rooms.
