Definitions

  • the invention relates to a method and an apparatus for feeding Printing ink in the inking unit of printing machines with an ink fountain, the one for metering Filling a cartridge is associated with a sliding cartridge piston has, which is pressurized pneumatically for pressing and the other end has a closable outlet opening to which a cartridge valve is assigned, the cartridge in a holder with a controllable pneumatic connection is arranged.
  • Such a device is described in DE 94 06 347 U1, the cartridge valve of which is shown in Shape of a sealing body at the upper end of an oscillating feed pipe and a sealing surface is formed on a carriage carrying the cartridge.
  • the Ink supply is interrupted when the feed tube is inclined, so that there is a Feed opening in the sealing body except opposite with a feed opening in the Sealing surface.
  • This device is not a sufficiently exact volumetric one Dosage of the printing ink possible.
  • U1 also shows a pneumatic cartridge squeezing device for Squeezing tubular cartridges with a mouthpiece at the front end and at the rear end through an inserted sliding cartridge bottom are closed.
  • the cartridge is received in a holder that one Compressed air connection has for feeding compressed air into the rear end of the cartridge, to apply a working pressure to the cartridge piston.
  • the present invention has for itself based on this state of the art Technology to create a method and an apparatus with which an exact volumetric dosing of the printing ink from the cartridge is made possible.
  • this object is achieved by a method with the features of Solved claim 1, which is characterized by the following process steps: The A pneumatic working pressure is applied to the cartridge, the position of the Cartridge piston is determined, the cartridge valve is opened, the Cartridge piston is moved to a preset target position and then the cartridge valve is closed when this position is reached. With these Process steps, the amount of paint supplied can be metered exactly, so that in the Printing machine can also be worked with minimal ink quantities in the ink fountain.
  • a device having the features of claim 3 solved which is characterized in that in the upper part of the bracket Distance sensor for determining the position of the cartridge piston is provided, and that Pneumatic actuating means are provided for opening the cartridge valve, the The cartridge and the actuating means are pressurized separately.
  • the distance sensor is as Ultrasonic sensor trained. With this inexpensive sensor is an exact path measurement of the cartridge piston reached.
  • Cartridge valve is designed as a lift valve, which can be controlled via pressurization is.
  • the cartridge valve is a pinch valve trained, which is also controllable via pressurization.
  • the cartridge valve is designed as a rotary valve, the is controllable via a pneumatic cylinder.
  • a sealing plate 3 which is supported on the holder 2 and one Compressed air connection 4, with which the cartridge piston 5 pneumatically is acted upon.
  • a sensor 6 is arranged in the sealing plate 3, which as Ultrasonic sensor can be formed and the respective position of the cartridge piston 5 measures in the cartridge 1 and passes the result to a control device.
  • a cartridge valve 7 which acts as a lift valve can be trained.
  • a lifting device 8 in the lower part of the holder 2 provided that has a compressed air connection 9, the 10 via a lifting plate Cartridge valve 7 opens.
  • the pressurization of the cartridge piston 5 can be controlled via a valve 11. which interacts with another valve 12 via which the cartridge valve 7 is opened.
  • the control unit not shown, which also receives the signals from the sensor 6 receives, initially applies a constant working pressure via valve 11 the cartridge piston 5 with the cartridge valve 7 closed. Is the position of the Cartridge piston 5 determined, the cartridge valve 7 is so long via the valve 12 opened until the cartridge piston 5 has moved into a preset desired position, which corresponds to a certain amount of squeezed paint. When this target position is reached the pressurization of the cartridge valve 7 via the valve 12 interrupted so that the cartridge valve 7 is closed again.
  • FIG. 2 shows a pinch valve 13, which is located at the outlet opening of the cartridge 1 is provided.
  • the hose pinch valve 13 consists of a hose 14, the one Valve body 15 is assigned.
  • the valve body 15 includes the hose 14 and contains a piston 16 with which the hose can be squeezed.
  • About one Compressed air connection 17, which is controllable by the valve 12, the piston 16 is so far proceed until hose 14 is closed.
  • To open the hose 14 is the Piston 16 is moved back into its starting position via a compression spring 18.
  • Fig. 3 shows at the lower end of the cartridge 1, a rotary valve 19 which at the Outlet opening 20 of the cartridge 1 is provided.
  • the valve body 21 has one Rotating insert 22, which has openings 23 similar to the outlet openings 20. By turning through about 90 °, the rotary insert 22 can be closed Turn the position as shown, or to a second position in which the Outlet openings 20 and the openings 23 of the rotary insert 22 match, so that Color can leak.
  • the controller itself can e.g. B. via a not shown Pneumatic cylinder take place, which is coupled to the rotary insert 22.
