Definitions

  • the invention relates to a device for supplying a printing press ink with ink.
  • the measures according to the invention advantageously result in a compact arrangement that can be operated without any significant effort. At the same time, it is ensured that the color cartridges can be easily replaced.
  • the use of compressed air for pressing out the color cartridges not only results in a high level of user-friendliness, but also enables the arrangement according to the invention to be easily integrated into an inking unit.
  • the squeezing unit can have a cylinder housing onto which the cover cap can be screwed.
  • the cylinder housing can support the cartridge that can be used here on the circumferential side.
  • the cylinder housing is therefore expediently provided with inwardly projecting support ribs in the region of its receiving channel assigned to the cartridge. This only results in a linear contact with the cartridge, which makes it easier to insert and remove a cartridge when changing the cartridge.
  • cover cap is provided with a connecting piece for a compressed air line. This advantageously enables a connection to any available compressed air source, for example a compressed air network, using a suitable hose.
  • the cover cap can advantageously have a collar which surrounds the connection piece and on which a valve for blocking the flow path passing through the connection piece is arranged.
  • the collar mentioned gives high stability.
  • the cylinder housing can have at least one holder provided on the circumference.
  • This can expediently be designed as a handle and / or as an add-on element which enables attachment to a machine-side support, for example to a slide which is displaceably received on a crossmember.
  • the inking unit on which FIG. 1 is based contains an ink gap which can be set between a roller 1 and ink knives 2 interacting therewith and to which an ink fountain 3 is arranged. A quantity of ink which can be metered by the ink knife 2 is removed by the roller 1.
  • a cartridge 4 containing the ink is provided, which is inserted into an extrusion unit 5 arranged above the ink fountain 3. This is attached to a carriage 6, which on a Roller 1 parallel traverse 7 is slidably received in the inking unit frame, whereby a distribution of the ink squeezed out of the cartridge 4 over the length of the roller 1 or a respective ink zone to be supplied is possible.
  • the cartridge 4 contains, as can best be seen from FIG. 2, a tubular cylinder 8 that functions as an ink reservoir.
  • This cylinder is provided at the front with an attached cap 9 which has a discharge nozzle 10 which can be fitted with a removable plug-in or screw closure or simply with can be provided with a tip that can be cut off.
  • the rear closure of the cylinder 8 is formed by a piston-like base 11 arranged in the cylinder 8.
  • the squeezing unit 5 contains a cylinder housing 12 in which the cartridge 4 can be inserted.
  • the cylinder housing 12 which can be designed as an injection molding made of plastic, is provided with a receiving channel 13 assigned to the cartridge 4.
  • the front end wall of the cylinder housing 12 is designed as a cartridge stop 14 which has a central opening which is designed such that only the dispensing nozzle 10 of the cartridge 4 fits through in the open state.
  • the front end wall of the cylinder housing 12 is provided with a collar 15 which surrounds the central opening and which has an outer collar at its end.
  • a rubber grommet 16 can be attached to the collar 15. In the example shown, this is designed as an angle grommet, which allows the emerging color strand to be deflected. This can be advantageous when the device according to the invention is arranged horizontally.
  • the lid cap 17 which is also made of plastic existing injection molding can be formed, has a groove formed here by a circumferential web, in which a sealing ring 18 is inserted. This is arranged such that it presses on the rear end face of the cylinder 8 of the cartridge 4 when the cover cap 17 is in position and thus causes a tight connection between the cover cap 17 and the cylinder 8.
  • the cover cap 17 is provided at the rear with a connecting piece 19 which contains a bore opening into the space sealed off from the sealing ring 18 and onto which a compressed air hose leading to a compressed air source can be plugged.
  • the compressed air network available in practically every printing company can be used as a compressed air source.
  • the connecting piece 19 is surrounded by a collar 20 of the cover cap 17, on which a valve 21 is received, through which the flow path passing through the connecting piece 19 can be opened and closed.
  • the valve 21 is provided with a switch button 22 for manual actuation.
  • the space located behind the piston-shaped base 11 and sealed to the outside by means of the sealing ring 18 is acted upon by compressed air.
  • This causes the piston to move forward, that is, in the squeezing direction, whereby a corresponding amount of paint is squeezed out through the discharge nozzle 10.
  • the squeezing pressure acts only on the cartridge 4 and the cover cap 17, which cooperates in a sealing manner therewith.
  • the cylinder housing 12 is not subjected to this. This can therefore support the cartridge-side cylinder 8 on the circumferential side.
  • the cylinder housing 12 can be provided in the region of its inner circumference with inwardly projecting support ribs 23 which are advantageously bevelled at the ends.
  • the cylinder 8 is in linear contact with this, which facilitates the retraction and extension process.
  • the cylinder housing 12 is provided on the outside with two bow-shaped holders 24 lying opposite one another. These can serve as a handle and / or as an attachment, with which attachment to a carrier is possible.
  • the cylinder housing 12 is, as has already been indicated above, fastened to the carriage 6 via one of the holders 24.
  • the other holder 24 can be used as a handle for manually moving the present arrangement along the crossmember 7, as a result of which it is possible to distribute the ink strand discharged from the cartridge over a greater length.
  • FIG. 1 the cylinder housing 12 is, as has already been indicated above, fastened to the carriage 6 via one of the holders 24.
  • the other holder 24 can be used as a handle for manually moving the present arrangement along the crossmember 7, as a result of which it is possible to distribute the ink strand discharged from the cartridge over a greater length.
  • the arrangement is selected such that the ink strand squeezed out of the cartridge 4 reaches the circumference of the roller 1 and is thus reliably transported to the ink gap between the roller 1 and the ink knife 2, which is a problem particularly economical ink consumption guaranteed.
