Definitions

  • the invention relates to a device for supplying at least two fluids to be mixed to a mixing device according to the preamble of claim 1.
  • two component base coats are used, among other things.
  • These paints e.g. B. Resin varnishes are mixed together depending on requirements from different components / fluids, such as. B. paints or solvents and the like.
  • B. paints or solvents and the like In order to be able to offer the broadest possible color spectrum and to be able to prepare a wide variety of paint compositions, a wide variety of colors and other mixture components such as B. Hardeners are kept ready.
  • individual paint components and hardener components e.g. isocyanates
  • a solution to the problem is a device according to claim 1.
  • a delivery device for delivering at least two fluids to be mixed to a mixing device is proposed, with a single drive motor with a clutch and with a feed pump per fluid, which expediently a corresponding Has clutch, wherein the feed pumps can be individually coupled to the drive. It is therefore advantageously possible to use only a single drive for two pumps, which enables the individual pump to only run when it is actually coupled to the drive, which is only the case when it is also needed.
  • the drive is expediently uncoupled from the first and coupled to the second, whereupon the latter is immediately ready for operation. This also enables a relatively quick change of color components.
  • the two feed pumps are fastened with their housing to a rotatable holder in such a way that their coupling side points away from the pivot point of the holder in a star shape. It is thus advantageously possible to simultaneously remove a pump from its coupling position with the drive with a single movement of the rotatable holder, while at the same time bringing the other pump into the coupling position. This saves time and promotes a precise coupling of the pump with the drive.
  • harden e.g. B.
  • a paint delivery system with a mixing device which has a color collector and a hardener collector for collecting colors and hardener and for delivery into a mixing container, as well as a static mixer, to which a device according to the invention is described based on the various exemplary embodiments .

  • two feed pumps 10 are shown arranged in a star shape around a pivot point 14 of a holder 12, which are connected via lines 20 to storage tanks for fluids, not shown, such as e.g. B. color components or hardeners are connected.
  • the feed pumps 10 which are designed here, for example, as double-acting piston pumps, are connected to the collector 26 by means of derivatives 22 via valves 24. Mixing components arriving in the collector 26 go beyond the common discharge line 28 from the collector 26 and are fed to their respective use.
  • the feed pump 10 shown on the left-hand side of FIG. 1 is connected via the drive rod 32 to the drive motor 34, which in the embodiment shown as an example is a piston motor operated by compressed air.
  • the drive motor 34 is supplied with compressed air with the interposition of intermediate components common to compressed air lines, such as filters, water separators and oilers.
  • a reciprocating piston located in the drive motor 34 moves up and down during operation, so that the piston rod 11 of the feed pump 10 is moved upward away from the axis of rotation 14 of the holder 12 via the drive rod 32 and back down again.
  • the feed pump 10 which is expediently used here is a double-acting piston pump which conveys both the upward and the downward stroke.

  • the coupling used here can be any type of snap or snap coupling.
  • the clutch gripper 18 can also be a pneumatically operated gripper which opens like a hand and which grips around a clutch head 16 of the feed pump 10, for example a mushroom head. Couplings of this type are known to the person skilled in the art, so that they are not specifically described here.
  • the holder 12 which is rotatably mounted in the bearing block 9 via the axis of rotation 14, can be turned back clockwise when the drive motor 34 is stopped, simply by hand the right feed pump 10 engages and rotates from the coupling position, which is shown here as a vertical position, into an adjacent position, whereupon the left pump is brought back into the coupling position at the same time.

  • the use of such delivery pumps is optional and useful in certain cases, e.g. B. the storage containers for the fluids are far from the place of use.
  • feed pumps 10 which are also expediently designed as double-stroke piston pumps, feed lines to valves 24, which are arranged on a collector 26.
  • the left bracket 12 which is provided with five feed pumps 10
  • color components are preferably fed to the collector, which is preferably designed as a color collector 26 on the left side.
  • the fluids collected here, for example paint components are brought to the mixing device 38 in the collector 26.
  • This mixing device 38 is assigned a mixer 40, which can be a static or dynamic mixer.
  • the illustration in FIG. 1 and shown here in FIG. 2 on the right-hand side of the two feed pumps 10 mounted in the holder 12 is used in the example shown here for the conveyance and metering of hardener components, which come from storage containers via pumps 44 via the holder 12 to the feed pumps 10 are promoted.
  • the supply of these hardener components to the mixing device 38 is carried out analogously to the supply of the color components.
  • a washing-up liquid pump 42 which is started up as desired either after changing the color, ie changing a feed pump 10 or after changing the hardener, which is also carried out by repositioning feed pumps 10.
  • the rinsing liquid which is fed from the rinsing agent pump 42 via the rinsing line 43 via valves 24 to the individual collector and mixing device components can be a pure cleaning agent or a solvent which is matched to the consistency and the composition of the individual color and hardener components.
  • the operation of the delivery device 8 via the adjustment of the feed pumps 10 depending on the requirement of a specific component functions in the case of the holder 12 provided with five feed pumps 10 on the left as well as that on the right Side bracket 12 shown, the operation of which has been described above.
  • the bores 13, which are made in the holder 12, can be seen, which can accommodate a locking pin attached in the position 15.
  • the engagement of the holder 12 via the bore 13 and the locking pin 15 facilitates the positioning of the feed pumps 10 below the clutch gripper 18 of the drive rod 32, not shown.

  • the delivery device which will be described in detail in FIG. 4, is also shown schematically in the middle.
  • the Fig. 3 actually serves only to describe the aggregates additionally used compared to the system shown in Fig. 2.
  • a pressure relief valve 54 is used on each feed pump 10 between the feed line and the department.
  • pressure relief valves 54 are optionally also attached.
  • a sight glass for the paint or hardener component to be conveyed can also be attached as required.
  • Filters 48 for filtering the conveyed material can optionally be used between the feed pumps 10 and the valves 24 of the collectors 26.
  • a pressure that can be read on the pressure gauge 46 can optionally be set via a pressure regulator 50.
  • the pressure gauges 46 can optionally also be equipped with limit switches. It goes without saying that with the arrangement shown on the right-hand side, which can expediently be used for supplying and metering hardener components, analog units can be used in the lines.
  • the delivery device 8, which is shown only schematically in FIG. 3, is shown there, wherein in the position rotated 90 ° to the left and right, it shows the holder 12 with the feed pumps 10 used. The delivery device is described in detail in FIG. 4. It should be assumed here that the left feed pump 10 represents a feed pump 10 shown on the left in FIG. 3.
  • FIG. 4 corresponds to one of the feed pumps 10 of the arrangement shown on the right side of FIG. 3.

If, due to a downward movement of the drive rod 32 of the drive motor 34, the left articulation point 64 moves downward, the right articulation point 64 moves upward, since the lever 56 is rotated via the thrust bearing 60, which is currently fixed in the thrust bearing holder 58.
  • the mixing ratio which is determined by the piston stroke ratio of the left and right feed pumps, can be seen in the arrangement of the counter bearing 60 between the two articulation points 64.
