Definitions

  • the invention relates to a pump arrangement according to the preamble of patent claim 1.
  • Pump-operated inking units are known from DE - 33 16 558 C2.
  • the stamping ink is constantly fed from a storage container via flexible hoses with the interposition of a pump system.
  • Peristaltic pumps and diaphragm pumps are used as the pump system.
  • imprecise routing of the hoses can lead to a malfunction and, after the machine has been idle for a long time and the paint has dried, bursting of the hose when it is started up again can lead to serious contamination of many machine parts.
  • the invention was based on the task of creating a pump arrangement for the ink supply to the inking unit for franking and stamping machines, which works reliably even with ink thickening and ink soiling and which can be used for high-performance franking machines.
  • threaded spindle can be operated as a vacuum or as a pressure pump. This enables variable adjustments to the consistency of the color as well as to constructive bonds.
  • the invention is explained in more detail below with the aid of a drawing.
  • the drawing shows the basic pump arrangement according to the invention, an embodiment with a suction threaded spindle being shown.
  • the Pumpenanordnuung consists of two paint containers 2, 5, one of which serves as an ink reservoir. Both paint containers 2, 5 are arranged one above the other, the upper paint container 5 also partially protruding into the lower paint container 2. When used in franking or stamping machines for a smaller number of frankings and thus lower ink requirements, the upper ink container 5 can be completely integrated in the lower ink container 2. Both paint containers 2, 5 are connected to each other by a guide tube 3. A threaded spindle 1 is mounted in the guide tube 3. The threaded spindle 1 is moved by an electric motor 7 as a pump unit via a coupling 6, for example formed from bevel and spur gears.
  • the coupling 6 can be structurally arranged inside or outside of the upper paint container.
  • the ink containers 2, 5 are connected to the inking unit 9 of the franking or stamping machine via separate pipe or hose connections 4, 8.
  • the ink is transported from the lower ink container 2 by means of the spindle into the upper container 5 by generating a negative pressure.
  • the paint is passed through the pipe or hose connection 8 into the inking unit 9 through its lower inlet connection.
  • the return flow of the paint that is not required via the higher outlet connection of the inking unit 9, the paint flows back through the hose connection 4 into the lower paint container 2.
  • an overpressure can also be generated by reversing the direction of rotation, which transports the paint from the upper paint container 5 into the lower paint container 2.
  • the inking unit 9 only the feed and discharge pipe or hose connections 8, 4 are to be exchanged.
  • an ink container 5 is placed in the other ink container 2. Furthermore, the complete drive, consisting of clutch 6 and electric motor 7, can be arranged within one paint container 5 for this purpose. The arrangement of the complete drive within the paint container 5 also avoids leaks.
  • the pump arrangement is controlled as a function of the franking or value stamp impressions, less wear and less heating of the ink can be achieved.
