Definitions

  • the invention relates to a device for supplying a Device for taking up highly viscous media with a such, in particular for supplying a color memory a printing machine with printing ink, with one with the highly viscous Filling channel that can be acted on, at least an outlet assigned to the receiving device.
  • a device for supplying a color memory Printing machine with printing ink of the type mentioned at the beginning is out known from DE 199 12 881 C2.
  • an over the ink fountain of a printing press filling channel connected to a paint supply line provided with several, distributed over its length, provided as cross holes, open at the bottom outlets is.
  • a shut-off valve is arranged in the paint supply line, by delivering paint to the paint box is controllable. By closing the shut-off valve the ink supply to the ink fountain is interrupted.
  • Residual paint can drip, the color in the Usually thin, slightly drying colored threads pull or completely dry out. This affects the print quality and the Reliability and is therefore undesirable.
  • the tongue opens automatically as soon as the supplied medium has a predetermined pressure reached. As soon as this pressure falls below the elastic restoring force the tongue falls off, this goes due to its spring action automatically return to their starting position in which the assigned Exhaust port is kept closed. tries have shown that the color thread here after a short time tears off and the existing upstream of the cover Residual paint can neither drip nor dry out.
  • the invention Measures thus result in a high level of functional reliability and at the same time ensure high production quality.
  • the cover element can advantageously be made of rubber-elastic Material existing disc to be formed by means of a union nut at the lower end of an outlet nozzle attached and delimiting with at least one tongue Slits is provided.
  • the cover element can advantageously be made of rubber-elastic Material existing disc to be formed by means of a union nut at the lower end of an outlet nozzle attached and delimiting with at least one tongue Slits is provided.
  • the ones intended to form the tongue or tongues are expedient Slits formed as cuts without material exceptions. This ensures that the side flanks each tongue over the entire thickness of the cover element Washer in sealing system on an assigned Mating surface come, which results in a reliable seal and at the same time to a desired self-cleaning of the above Surfaces leads.
  • this can Cover element several, adjoining, ring-shaped arranged, triangular cut tongues. In this way, a comparatively large cross section can be created reach the assigned outlet opening.
  • a particularly preferred embodiment is that at a disc-shaped cover element made of polyurethane with a diameter of 22 mm and a thickness of 2 mm the length of the side edges of the tongues is 5 mm.
  • the printing press 1 indicated in FIG. 1 contains one Duktorwalze 2, the one by grazing on the Duktorwalze 2 Color knife 3 is assigned limited color box 4.
  • the Ductor roller 2 acts with further, not shown Inking rollers together.
  • the color box 4 becomes color fed. It is a honey-viscous, highly viscous Medium.
  • the supply device provided for this contains an in the printing press built-in filling unit 5, which a a paint supply line 6 to which paint can be applied, via which Paint box 4 passing manifold 7 and this one upstream, arranged in the ink supply line 6 Shutoff valve 8 has.
  • the distributor pipe 7 is provided with several provided over its length outlet connector 9.
  • the distributor pipe 7 can, as best seen in Figure 2 is designed as a hollow rail closed at the end be, the interior of which via a nipple 10 to the paint feed line 6 is connectable and in the area of its bottom with the color box projecting over his Length distributed outlet connector 9 is provided. These contain one each communicating with the interior of the distributor pipe 7 Drilling.
  • the shut-off valve 8 can be used together with the associated actuator in the manifold 7 forming hollow rail can be integrated.
  • the ink supply line 6 starts from an ink source that here from a paint container 11 and one connected to it Pump 12 is there so that the paint under pressure to Is made available. Usually is for all paint boxes the printing press 1 a color source is provided. The Pump 12 can therefore always be in operation. But it would be too conceivable, the pump 12 together with the shut-off valve 8 activate or passivate.
  • the ink fountain 4 assigned fill level detector may be provided. Once the Fill level in the ink fountain 4 drops below a predetermined level, becomes the actuating device assigned to the shut-off valve 8 controlled by the level detector so that the shut-off valve 8 opened and accordingly the interior of the manifold 7 pressurized paint is that can exit through the outlet 9. Once the Fill level in the ink fountain 4 reaches a predetermined maximum level has the shut-off valve 8 in the closed position brought.
  • the outlet 9 can be removed with at its lower end provided a cover member 13 which opens as a pressure and automatically closes when the pressure drops Organ is trained.
  • the cover member 13 is made of elastic material, preferably rubber-elastic material, like rubber-elastic plastic, for example in shape of polyurethane, existing disc formed by means of an associated union nut 14 at the lower end of assigned outlet 9 is attached.
  • the cap nut 14 has an undercut into which the assigned disc-shaped cover element 13 is inserted.
  • the outlet ports 9 are in several parts formed, an upper, with the manifold 4th screwed section and a lower one, the union nut 9 load-bearing section and a center piece are provided, the one not shown in Figures 3 and 4 Restrictor can contain.
  • the disk forming the cover member 13 is as best can be seen from Figure 5, with through in the center of the pane intersecting slots 15 formed, arranged in a ring, triangular tongues 16 provided, when depressurized Interior of the manifold 7 are coplanar and close to each other in the area of the slots 15 and which, as indicated in Figure 4, elastic under pressure can dodge downwards, so that one in FIG indicated outlet opening 17 through which a color strand 18 can emerge.
  • the tongues 6 spring from that of FIG. 4 lying open position in the figure 3 based lying closed position, whereby the outlet opening 17th is closed and dripping or drying out of Residual color is effectively prevented.
  • the one indicated in FIG. 5 is Angle ⁇ between the slots 15 60 °, so that over the whole circumference 6 adjoining, arranged in a ring Tongues 16 result.
  • the laterally delimiting the tongues 16 Slots 15 are useful as material-free Incisions formed so that the tongues 16 in the figure 3 underlying closed position in the area of the whole Thickness of the cover element 13 in mutual, sealing contact come.
  • the coming into mutual sealing facility Side flanks brush each other off, which is one Self-cleaning results.
  • the disc-shaped cover element 13 a diameter d of 22 mm and a thickness of 2 mm, i.e. less than a tenth of the diameter.
  • the length of the intersecting slots 15 in the middle is 10 mm, so that a length 1 of the side flanks of the tongues 16 of 5 mm, that is less than a quarter of the diameter d results.
  • the starting material for the production of the disc-shaped Cover elements 13 can be a polyurethane film with the desired thickness of 2 mm can be used.
