Definitions

  • the invention relates to a device for supplying fluid dispensing devices with a fluid consisting of a fluid pump which can be connected to a fluid supply, a filter for the fluid, if necessary, a pressure reducer and a distributor.
  • Such devices are used in particular for the supply of Adhesive applicators are needed in industrial applications there in different versions known.
  • a widely used device this type is the applicant under the short name WM 360 distributed.
  • This device has a submersible pump, which is in a container introduced with liquid adhesive and from one on the lid of the Adhesive container attached drive device is actuated.
  • the Submersible pump carries a line out of the container to a filter a number of outlets to which different dispensers for the adhesive can be connected.
  • the known pump is a compressed air operated piston pump, and at the known container is a container, which in sales is used by adhesive. To start up the device only needs the Cover of the known container removed and through the pump and the Filter carrying container of the known supply device replaced become.
  • the invention is therefore the object of a device for Supply of fluid dispensers to create, compared to the state of Technology is more flexible and easier to configure.
  • the task is characterized solved that the distributor directly to the pressure outlet of the pump is connected and at the time has at least one fluid outlet, the can be connected to the high pressure filter.
  • the solution of the invention provides increased flexibility of use the supply device with it.
  • the provision of a distributor immediately at the pump and before the filter allows to connect the filter (s) the distributor with comparatively long and large diameter pipes, so that the fluid supply largely independent of the dispensing devices can be positioned without a significant pressure drop in the long Connection cables have a negative impact on the quality of the order and so that the product quality needs to be feared.
  • Fig. 1 shows a fluid pump 10 with attached distributor 12.
  • the fluid pump 10th has a shaft 14 which passes through the distributor 12 centrally and at its in FIG. 1 lower end has an intake 16.
  • a suction tube or suction hose is connected, which in one in the Drawing not shown fluid supply leads, from which the fluid pump 10th sucks.
  • the combination of fluid pump 10 and manifold 12 is on the horizontal leg 18 of an angle plate 20 attached that in turn to Attaching the combination to a wall serves and best in Fig. 3 to recognize.
  • a compressed air connection 22 Part of the fluid pump 10 are a compressed air connection 22 with attached Pressure gauge 24.
  • the compressed air serves as the drive medium for a double piston 26a, 26b (Fig. 4), which is explained in more detail below.
  • the manifold 12 has two ports for two fluid output lines 28, 30.
  • the distributor can draw more than the two Outputs for the lines 28, 30 have. Unused outlets can with be closed a blind plug 64, none of which, however, in Fig. 1 is shown.
  • This filter 32 is connected by means of a fluid line 34 with a Pressure regulator 36 connected.
  • the pressure regulator reduces the pressure on its side the line 34 prevailing high pump pressure to a low pressure in the order of a few bar, with which the fluid over another Fluid line 38 passes from the pressure regulator 36 to a fluid dispenser 40.
  • the fluid conduit 30 has a large diameter and can be a considerable Have length while the fluid line 38 is in contrast short and the Pressure regulator 36 is located relatively close to the fluid dispenser 40. On this way, between the fluid pump 10 and the fluid applicator 40th a considerable distance. Nevertheless, no remarkable occur Pressure fluctuations of the fluid on the dispenser, because it the pressure regulator is closely adjacent.
  • FIG. 2 shows a variant of the arrangement according to FIG. 1.
  • the Filter 32 immediately, i. omitting the fluid outlet line 30 to the Distributor 12 connected and attached to the angle plate 20.
  • the pressure regulator 36th via a sub-distributor 42 three applicators 40, 40 ', 40 "are connected. This design demonstrates the flexibility of the system.
  • FIG. 3 is a perspective view of the combination of fluid pump 10, Distributor 12 and filter 32 for an arrangement according to FIG. 2.
  • the filter 32 has multiple outlets that are independent of each other Pressure regulators can lead, without this, however, would be presented.
  • FIG. 4 is a schematic longitudinal section through that shown in FIG Combination. Recognizable here is the above-mentioned double piston 26a, 26b of Fluid pump 10. This double piston acts via a plunger 50 on a Reciprocating piston 52. This is movable in a suction chamber 54 back and forth.
  • the outflowing fluid passes outside of the shaft 14 in the manifold 12th
  • This has in the embodiment a central through hole with a Diameter, which corresponds to the outer diameter of the shaft 14 and is opposite to the shaft 14 by means of two circumferential O-rings sealed, as can be seen in detail in Fig. 4 well.
  • the outlets 58 continue in the radial direction. And that is starting from the central bore of the distributor 12 in its inner wall a circumferential annular channel 60. From this annular channel go in Embodiment two radial holes 62 to the outside. These form each an output channel from the manifold 12th
  • the other bore conducts this from the annular channel 60 under high Pressure flowing fluid in the already mentioned filter 32 and from there to the delivery points.
  • fluid pump 10 and manifold 12 are at their common axis 68 rotatable relative to each other and preferably also after Setting a specific position to each other can be determined. Together is the combination then - as mentioned above - on the angle plate 20th or otherwise fixed in place.
