Definitions

  • the invention relates to a device for disposing of ink or similar media from a container, to which a roller is assigned, in a rotary printing press.
  • the invention is particularly suitable in offset rotary printing machines for removing ink from an ink fountain or from an ink roller washing device, e.g. from a squeegee trough, as well as to remove paint from a paint container.
  • a device of this type is known from DE 4 224 775 A1.
  • a separate waste container is placed on the back of the ink fountain.
  • the paint is manually removed from the ductor and from the bottom surface of the paint box by means of a doctor blade and emptied into the residual collection container in the latter.
  • the object of the invention is to develop a solution which noticeably reduces the disadvantages mentioned above.
  • the task is solved according to the characterizing part of the main claim. Further training results from the subclaims.
  • the device according to the invention enables short cleaning times, improves the working conditions for the operator and helps to solve upcoming disposal problems.
  • Vegetable oils or natural oils, surface tension-reducing emulsifiers and water are suitable as preferred cleaning liquids or mixtures.
  • the cleaning liquid is supplied from a reservoir under high pressure via a line system with pumps. Furthermore, the cleaning liquid can also be injected into the container to be disposed of (ink fountain, squeegee tray) after a defined cleaning cycle, for example with a cyclical supply.
  • the cleaning liquid is distributed into this container via a linear flow and / or a vortex flow.
  • Spray gyros or spray pipes integrated into the cover are suitable for distribution.
  • the cleaning liquid strikes the interior of the container, the remaining printing ink in the ink fountain as well as the partial peripheral surface of the roller assigned to the container as one impact jet or several impact jets.
  • the sprayed-in cleaning liquid emulsifies with the paint or lacquer remaining in the container to form a flowable mixture.
  • the mixture is collected by suction in a container with a separator and / or filter and separated.
  • the cleaning liquid prepared in this way is fed to a storage container, from which a renewed one Cleaning cycle can be started.
  • the separated paint is removed from the collection container and disposed of.
  • the device according to the invention is not limited to a stationary system, rather it is also suitable for portable use, for example at different printing units or finishing stations of a printing press. If the cover is designed appropriately or if the openings of the ink fountain, squeegee tray or coating container are identical, universal disposal can be carried out using the same device.
  • an ink fountain 2 with an ink fountain roller 1 is arranged in the inking unit of an offset printing press.
  • the ink fountain 2 is designed as a housing open on one side, on which a cover 3 is detachably fastened.
  • the cover 3 is arranged tightly on the ink fountain 2, so that a hermetically sealed chamber is formed with the adjacent ink fountain roller 1.
  • the cover 3 is placed on the ink fountain 2 or is detachably connected to the ink fountain 2.
  • the cover 3 can be put on or removed manually or also with a guide gear, for example a coupling gear, or a swivel mechanism.
  • the cover 3 is coupled to a line system 4 for the supply of the cleaning liquid, to which a pump 5 and a storage container 6 are arranged upstream in order to receive the fresh cleaning liquid in a conveying direction 13.
  • the cover 3 is also provided with a line system 10 for the disposal of the mixture or the emulsion of cleaning liquid and paint provided, which is followed by a collecting container 9 in the conveying direction 11.
  • a device 14 is integrated in the cover 3, which is used to feed paint into the ink fountain 2.
  • the device 14 is connected to one or more ink reservoirs, for example ink cartridges.
  • the containers 9 and 6 are coupled to one another by a connecting line 12.
  • an ink roller washing device is integrated into the inking unit.
  • a spray device (not shown) is arranged upstream in the compactor for supplying the cleaning liquid.
  • the actual ink roller washing device is associated downstream of an ink-guiding roller, for example an ink fountain pen 8.
  • the ink roller washing device consists essentially of a doctor blade trough 7, which can be turned on and off the ink fountain 8.
  • the squeegee trough 7 is designed as a container which is open on one side at the top and has a squeegee blade inclined towards the ink fountain pen 8.
  • a cover 3 is releasably placed, which hermetically closes it.
  • the cover 3 can be put on or removed manually, with a guide gear or a swivel mechanism.
  • the cover 3 is provided with a line system 10 for disposal of the mixture or the emulsion of cleaning liquid and paint in a collecting container 9.
  • a line system 4 for supplying cleaning liquid from an upstream storage container 6 can additionally be connected to the cover 3, analogously to FIG. 1.
  • the cleaning liquid is supplied under high pressure and hits the inking roller and the squeegee tank as an impact jet.
  • the geometric shape of the cover can also be designed so that the doctor blade is also covered.
  • the mode of action is as follows: 1, the cover 3 is detachably connected to the ink fountain 2, so that the ink fountain 2 is encapsulated.
  • the cleaning liquid is sprayed from the reservoir 6 with a pump 5 into the ink fountain 2 via the line system 4.
  • the remaining color from the ink fountain 2 is dissolved by the cleaning liquid, so that a flowable mixture of color and cleaning liquid is formed.
  • the mixture is drawn from the ink fountain 2 via the line system 10 in the conveying direction 11 using a pump into the collecting container 9.
  • the container 9 serves as a collecting container for the color-cleaning agent mixture and is also designed as a separator and / or filter.
  • the separated mixture can be disposed of and the filtered detergent mixture is fed to the storage container 6 via a connecting line 12 and is available for a further washing cycle.
  • the ink fountain roller 1 can be cleaned simultaneously with the ink fountain 2 by spraying the partial circumference of the ink fountain roller 1 facing the ink fountain 2 over the cover 3 with cleaning fluid under high pressure.
  • the loosened paint is scraped off by the rotating ink fountain roller 1 by means of an ink slide, via the line system 10 of the cover 3 and sucked out of the ink fountain.
  • the ink fountain roller 1 can be cleaned separately from the washing cycle or together with the ink fountain 2.
  • the cover 3 is detachably connected to a doctor blade trough 7.
  • Cleaning liquid is sprayed onto the rollers via the spray device arranged upstream in the roller train, the rollers are rotated and cleaned via the roller train.
  • the doctor blade trough 7 is placed on the ink fountain 8 located downstream and scrapes off the ink / cleaning liquid mixture. Via the cover 3, the mixture is sucked into the collecting container 9 using the line system 4.
  • another can be placed in the cover 3 analogously to FIG. 1
  • Line system 4 for the direct supply of cleaning liquid can be integrated into the doctor blade trough 7.
  • the cleaning tent is considerably shortened by the impact of the impact jet.
