Definitions

  • the invention relates to a printing press for the production of printed products and a set-up method for setting up a printing press with an ink guide part, in particular an ink tray and / or a doctor blade chamber.
  • Printing machines are known from the prior art which are used to produce printed products.
  • Such printed products can be, for example, print media, packaging or another flat material to be printed.
  • a flexographic printing press for example, several inking units are usually arranged around an impression cylinder, so that the inking units are at different heights.
  • the inking units may change due to production-related requirements in particular in an overhead area and / or at a height of the printing machine that is difficult for an operator to reach.
  • To prepare for the production of the printed products however, it is often necessary to replace individual ink guide parts of the inking units. Such an exchange may also be necessary, for example, due to wear of an ink guide part or due to an image change of the printed product.
  • the ink guide parts can comprise an ink tray and / or a doctor blade chamber, through which ink is processed within the inking unit, so that the print image of the desired printed product is generated.
  • inking units at certain heights it can require a high degree of physical strength for the operator to convey the respective ink tray and / or the respective doctor chamber into the printing press, since these are often heavy and unwieldy.
  • a further disadvantage of known systems is that the printing machine for exchanging the ink guide parts is often stopped for a long time, as a result of which the production time for the production of the printed products is interrupted. It is therefore desirable that at least the color guide part to be replaced is already available to an operator in the vicinity of the exchange position as comfortably as possible.
  • a printing press has at least one receiving bearing for receiving an ink guide part.
  • the ink guide part can in particular be an ink tray and / or a doctor chamber.
  • the printing press has a work platform and a lifting device for lifting the ink guide part for the receiving bearing.
  • the lifting device further comprises a lifting unit for receiving the ink guide part and a fastening section which is fastened to a support element of the printing press.
  • the lifting unit is at least movably mounted relative to the fastening section between a feed position and a removal position elevated to the feed position, the ink guide part being able to be picked up by the lifting unit in the feed position and the ink guide part being removable from the lifting unit in the removal position above a height of the working platform.
  • the ink guide part can thus be conveyed from the feed position to the removal position by the lifting unit.
  • the ink guide part can preferably be designed to provide ink in the printing press, to take up ink and / or to transport ink.
  • the lifting unit is designed to receive the ink guide part in the feed position below the height of the work platform.
  • a region located below the work platform can be understood to have a lower height, in particular to a floor area, than the work platform.
  • the area below the work platform can preferably extend directly below the work platform and / or next to the work platform.
  • a region located above the work platform can be understood to have a greater height than the work platform.
  • the area above the work platform can preferably extend directly above the work platform and / or next to the work platform.
  • the lifting unit thus forms, in particular, a lift by means of which the ink guide part on the printing press can be raised into a position which is favorable for the operator for replacing or setting up the ink guide part in the printing press.
  • the lifting unit is also mounted on the printing press, in particular so that the fastening section is mounted in a fixed position relative to the printing press. This can ensure that, on the one hand, secure mounting of the lifting unit is guaranteed, since the support element of the printing press represents a fixed reference point. Furthermore, external influences during production lead within the Production area by attaching the fastening portion to the support element in particular or less likely to adjust the lifting device.
  • the storage of the lifting unit can thus be adapted to the rest of the printing press and the production conditions.
  • the printing press can preferably be a flexographic printing press.
  • the lifting unit can be adjusted on the fastening section in order to change between the feed position and the removal position.
  • the height of the work platform can in particular be understood to mean a distance from the work platform, preferably a step level of the work platform, to a floor area.
  • the fact that the removal position is increased to the feed position means in particular that the lifting unit in the removal position is at a greater distance from a floor area of the printing press than in the feed position.
  • the lifting unit can be operated in a simple manner from the floor in the feed position and the ink guide part can be removed easily in the removal position.
  • a receiving bearing of the printing press to be equipped can be reached via the work platform, in particular even if the receiving bearing is inaccessible from the ground.
  • the lifting unit can be loaded with the ink guide part while the printing press is in production and can be moved from the feed position to the removal position.
  • the printing press can then be stopped and the ink guide part can be mounted in the printing press in a position which is comfortable for the operator.
  • this increases the occupational safety of the operator, since he only handles the ink guide part in a certain area, and on the other hand, part of the set-up time for setting up the printing press can overlap with the production time for producing the printed products by the printing press, so that the effective loss of production is reduced can.
  • the fastening section can preferably comprise a screw connection to the support element.
  • the support element is in particular designed to at least partially absorb and / or carry a load of the lifting device.
