Definitions

  • the invention relates to a doctor blade chamber carrier of a printing machine for fastening a doctor blade chamber, which cooperates with a metering roller in a printing operating position, and a corresponding method for fastening a doctor blade chamber to a doctor blade chamber carrier.
  • the original system is the submersible roller inking unit (3-roller inking unit), which for example comes from DE 29 42 521 C2 is known.
  • the ink is metered by squeezing the excess ink in the nip between the dip roller and anilox roller.
  • the squeegee chamber system has therefore established itself as a further inking unit type, which offers the advantage of very easy-to-dose ink transfer with simultaneous repeatability.
  • the open and the closed system With the squeegee chamber system, a distinction is again made between the open and the closed system, whereby the closed system has largely prevailed since it also enables automatic cleaning of the anilox rollers and all ink-carrying parts and thus fast and automatable job and ink changes.
  • a closed doctor blade chamber system according to the prior art is known for example from US Pat EP1 302 315 B1 known.
  • a remaining problem of such a doctor blade chamber system is, however, the fact that various measures have to be taken to ensure tightness, which entail constant and not negligible maintenance.
  • those in the EP1 302 315 B1 mentioned face seals are regularly replaced and renewed to ensure the tightness of the closed doctor chamber system.
  • the performance of maintenance work on a closed doctor blade chamber system is in turn impaired by the fact that the doctor blade chamber is difficult to access within the printing press. So the closed doctor chamber system comes according to the EP1 302 315 B1 usually used in a central cylinder printing machine, such as this from the WO 2009/144016 A1 is known. This means that typically 8 closed doctor blade chamber systems are arranged around the central cylinder. Since the central cylinder forms a sensitive core in every central cylinder printing machine, maintenance work on the doctor blade chamber systems in its vicinity may only be carried out with extreme caution and only by trained specialist personnel. This aspect also increases the costs for any maintenance work on the doctor blade chamber systems.
  • the object of the invention is therefore to reduce the maintenance outlay of the inking units known in particular from the flexographic printing sector.
  • Fig. 1 shows a perspective view of the doctor blade chamber carrier according to the invention.
  • the doctor blade chamber carrier 101 has two side parts 102 and 103 which are connected to one another by a strut 104 and a holding plate 105.
  • a plurality of guide rails 106, 107, 108, 109, 110 and 111 are provided on the upper side of the doctor blade chamber carrier 101, on which the attached doctor blade chamber can be moved.
  • a cylinder 112 On the underside of the squeegee chamber carrier 101, a cylinder 112 is provided with which the two bolts 113 and 114 can be actuated. In addition to the bolts 113 and 114 there is a stop 115 and 116.
  • nozzles 117 and 118 At the ends of the holding plate 105 there are in each case nozzles 117 and 118, with which a sealing connection to the ink circuit on the machine side can be produced in the printing operating position.
  • Fig. 2 shows a perspective view of the doctor blade chamber carrier 101 from Fig. 1 with attached doctor chamber 201.
  • the reference symbols of the doctor chamber carrier correspond to the reference symbols Fig. 1 , so refer to the explanations above Fig. 1 can be referred.
  • With the directional arrow 202 Direction of displacement indicated, in which the attached doctor chamber 201 can be moved against the stops 115 and 116.
  • Fig. 3 shows a perspective view of the doctor blade chamber carrier Fig. 2 with advanced doctor chamber.
  • the reference symbols correspond to the reference symbols Fig. 1 and Fig. 2 , so refer to the explanations above Fig. 1 and Fig. 2 can be referred.
  • the doctor chamber 201 is now displaced against the stops 114 and 115 and is fixed in the lateral direction by the guide rails 108, 109, 110 and 111.
  • the squeegee chamber 201 is thus held in a form-fitting manner on the squeegee chamber carrier 101, with the exception of one degree of freedom, the one degree of freedom being capable of being acted upon by at least one switchable and reversible bolt in such a way that the bolt keeps the squeegee chamber at a distance from the squeegee chamber carrier or fixes it to the squeegee chamber carrier.
  • the arrow 301 points to the visible distance that the doctor blade chamber 201 has when the bolts 113 and 114 are extended relative to the holding plate 105.
  • Fig. 4 shows a perspective view of the doctor blade chamber carrier Fig. 3 with fixed squeegee chamber.
  • the reference symbols correspond to the reference symbols Fig. 1 , Fig. 2 and Fig. 3 , so refer to the explanations above Fig. 1 , Fig. 2 and Fig. 3 can be referred.
  • the difference between the state in Fig. 3 and the state in Fig. 4 now consists in that the bolts 113 and 114 were actuated downward, so that the doctor chamber 201 is thus fixed to the doctor chamber carrier 101.
  • the arrow 401 shows that the doctor chamber 201 is now opposite the state in FIG Fig. 3 was lowered.
