Definitions

  • the invention relates to a device for the metered filling of a viscous paste from a storage container into a cylindrical filling container with a filling tube which can be immersed in the filling container and with a shut-off, through which the paste is pressed during the filling process by means of a piston from an intermediate container into the filling container, the piston has a cross-sectional area which corresponds to that of the filling container, and with a filling line with a shutoff connecting the storage container to the intermediate container.
  • the intermediate container there is designed as a measuring cylinder with a piston such that the The inside diameter of the measuring cylinder - and thus also the cross-sectional area of the piston - corresponds to the inside diameter of the filling container in question.
  • the lower end of the filling tube is pulled upwards in accordance with the level of the filled paste in the filling container, so that the paste is filled without air pockets.
  • the device has proven itself in and of itself.
  • there are relatively high pressures required to fill the measuring cylinder because it has to be filled using a three-way valve.
  • the measuring cylinder with pistons and other associated components must be replaced if the paste is to be filled into a filling container with a different cross-section.
  • DE-OS 2 551 331 describes a metering device with a plurality of plungers with axial bores which are immersed in their cylinders.
  • a viscous paste cannot be filled with this known device because a vacuum of at most 1 bar is available for filling the cylinder (atmospheric pressure).
  • the invention has for its object to develop a device of the type mentioned in such a way that, while maintaining the principle that the mouth of the filling tube follows the level of the filled paste in the filling container during the filling process, throttling points during the filling process into the intermediate container as well as sealing problems are avoided and one Adaptation of the device to fill containers with other cross sections is simplified.
  • the invention is characterized in that the intermediate container is fixed, that the piston is designed as an exchangeable plunger with an axial bore that continues via a first shut-off valve in the line cross-section of the filling pipe, and that a second shut-off valve is provided, which Filling line connects to the intermediate container.
  • the lower end of the plunger stands on a recess of a plate connected to a piston-cylinder unit.
  • the plunger is also inserted into the intermediate container during the filling process via this piston-cylinder unit.
  • the device shown has a frame-fixed upper plate with which two piston-cylinder units 2 are connected.
  • an upper, second shut-off valve 3 sits on the plate 1 and is inserted into a filling line 4.
  • the filling line is led to an intermediate container 5 which is also arranged fixed to the frame and which is designed as a hollow cylinder which is closed on its underside by an annular flange 6.
  • a plunger 7 is sealingly inserted into the opening of the ring flange.
  • the ring flange is fastened to the intermediate container 5 in an easily replaceable manner by means of a union nut 8.
  • a plate 9 is firmly connected to the pistons of the units 2 and can be raised or lowered in the direction of the double arrow 10.
  • the plate 9 has a recess 11 which is adapted to the plunger 7 and into which the lower end of the plunger 7 is inserted.
  • the plate has a downwardly tapering bore which is guided to a lower, first shut-off valve 12. This in turn continues down to a filling pipe 13.
  • a filling container 14 to be filled with a paste for example a cartridge or a tube, is inserted into a receiving piece 15 from above.
  • the receiving piece is in turn inserted into a hole in a rotary table 16 with the interposition of a chuck 17.
  • the rotary table has several such receptacles for filling containers on the same circular arc.
  • a plate 18 which can be raised by a pneumatic lifting cylinder 19.
  • the operation of the device is as follows: At the beginning of a filling cycle, the plunger 7 is completely drawn into the intermediate container 5 by a corresponding actuation of the piston-cylinder units 2.
  • the intermediate container 5, the filling line 4 and also the plunger 7 with the filling pipe 13 are, as indicated in the drawing, filled with a viscous paste. Both taps 3, 12 are closed.
  • the filling container 14 is in a lower, lowered position (see FIG. 1).
  • the upper shut-off valve 3 is then closed and the lower shut-off valve 12 is opened (see FIG. 3).
  • Fig. 4 shows the filled filling container 14, which now only needs to be closed.
  • the lifting cylinder 19 is actuated again, which lowers the filled filling container 14 downwards, as shown in FIG. 5.
  • the lower shut-off valve 12 is closed after the upper shut-off valve 3 has already been closed in the step according to FIG. 3. 5 has been reached and the cycle can begin again after a new filling container 14 has advanced under the mouth of the metering tube 13.
  • the cross-sectional area of the plunger 7 is equal to the clear cross-sectional area of the filling container. Because both parts are circular cylindrical, the outer diameter of the plunger is equal to the inner diameter of the filling container 14. The arrows 20 in FIG. 1 indicate these diameters which are the same as each other.
  • the diameter of the axial bore of the plunger 7 can be chosen freely if the condition specified above is met.
  • the diameter of the axial bore of the plunger 7 is preferably chosen to be as large as possible because the flow resistance in the axial bore is small. This is a major advantage of the new device.
  • the new device manages with a pressure of 70 to 80 bar at a cycle of 15 per minute, compared to a pressure of 180 bar with the same cycle in the device according to the aforementioned DE-A 2610396.
  • the pressure can so be more than halved. This is due to the larger cross sections and the shorter distances that the paste has to travel in the device.
  • the new device therefore works more gently.
