Definitions

  • the invention relates to a wobble piston pump for metering a coating agent in a coating system.
  • Such a wobble piston pump is off EP 1 348 487 A1 known.
  • a substantially cylindrical wobble piston in a cylinder carries out a tumbling movement, which consists of an oscillating stroke movement and a superimposed rotary motion.
  • the rotational movement of the wobble piston in this case serves to open or close an inlet or an opposite outlet in the cylinder, while the oscillating stroke movement fills the coating agent into the cylinder or ejects it out of the cylinder.
  • the wobble piston is in this case driven by a rotating drive shaft via a transfer gear, wherein the transfer gear converts the pure rotational movement of the drive shaft in the tumbling motion.
  • a disadvantage of this known wobble piston pump is the fact that the flow rate of the wobble piston pump pulsates strongly, which is undesirable in the metering of coating agents (such as paint) in a coating system. Rather, it is desirable when used in a coating system for metering paint that the flow rate is as constant as possible according to the desired value.
  • the invention is therefore based on the object to provide a correspondingly improved wobble piston pump.
  • the invention includes the general technical teaching to provide a plurality of pump units in a wobble piston pump, each having a cylinder and a wobble piston, which performs a tumbling motion in the cylinder during operation.
  • the individual pump units each convey - like the conventional wobble piston pump described at the beginning - a pulsating flow of the coating agent.
  • the individual pump units are connected on the outlet side to a common pump outlet, so that the delivery flows of the individual pump units overlap, which leads to a smoothing of the pulsation.
  • the pump units of the wobble piston pump according to the invention are preferably also connected on the inlet side to a common pump inlet, so that the pump units are filled with the coating agent via the common pump inlet.
  • the wobble piston pump has three parallel pump units, which represents a good compromise between the demand for the lowest possible pulsation of the flow on the one hand and the demand for the lowest possible weight.
  • the invention is not limited to wobble piston pumps with three pump units connected in parallel. Rather, it is also possible within the scope of the invention to connect a larger or a smaller number of pump units in the wobble piston pump in parallel.
  • the wobble piston pump 2, 4, 5 according to the invention or even 6 pump units connected in parallel The optimum number of pump units depends on the requirements for the uniformity of the flow rate and on the weight of the wobble piston pump.
  • the wobble piston pump is suitable for the separate conveying of several components (eg base lacquer and hardener) of the coating agent.
  • the various components of the coating agent in the wobble pump have no contact with each other to prevent a chemical reaction between the various components.
  • at least one pump unit is provided in each case.
  • a plurality of pump units which are interconnected on the outlet side and / or inlet side and which jointly convey the respective component, may also be provided for each component of the coating agent.
  • a smoothing of the delivery flow of the respective component is achieved.
  • the wobble piston pump according to the invention can have a total of six pump units, with three pump units jointly conveying a first component (eg stock paint), while the other three pump units jointly promote a second component (eg hardener).
  • the drive of the wobble piston pump according to the invention is effected by a common drive shaft, which can be driven for example by an electric motor and thus rotates during operation. Between the rotating drive shaft and the individual pump units, a transfer gear is arranged in each case, which converts the pure rotational movement of the common drive shaft in the combined tumbling motion (rotational and lifting movement) of the wobble piston.
  • the power transmission from the common drive shaft to the various pump units is preferably carried out by a gear transmission.
  • this gear transmission has a ring gear with an internal toothing and a plurality of planetary gears engaging in the ring gear, each with an external toothing.
  • the common drive shaft in this case drives the ring gear, so that the individual planetary edges rotate with a corresponding ratio, wherein the individual planetary gears in turn each drive one of the pump units.
  • the gear transmission has a central sun gear with external teeth and a plurality of planetary gears engaging in the sun gear each having an external toothing, wherein the common drive shaft drives the central sun gear, so that the planet gears rotate with a corresponding translation.
  • the individual planetary gears of the gear drive then again drive each one of the pump units.
  • the invention is not limited to the variants described above with regard to the structural design of the gear transmission. Rather, the power distribution from the common drive shaft to the various pump units can also be realized by other types of transmissions.
  • the individual pump units are preferably driven with a certain phase difference, so that the time course of the flow rates of the individual pump units is correspondingly out of phase.
  • the phase difference is equal to 360 ° divided by the number of pump units.
  • the phase difference between the individual pump units is therefore preferably 120 °.
  • the individual wobble pistons preferably consist of a composite of different materials (eg ceramic and steel), which on the one hand enables economical production and on the other hand allows a long service life and, moreover, is associated with a low weight.
  • the piston head (conveying head) of the wobble piston made of ceramic
  • the piston skirt (piston skirt) consists of steel.
  • the two materials of the composite are preferably glued together, pressed or screwed together.

  • the individual pump units are preferably made of low-wear materials.
  • the pump units may have material pairings in which both materials are hard.
  • material pairings are possible in which a relatively hard material is paired with a relatively soft material.
  • the individual pump units are mechanically connected by a separable coupling with a continuous drive shaft.
  • the individual pump units can thus be selectively engaged or disengaged.
  • the one pump unit, which is to perform a conveying work, is thereby connected to the common drive shaft and driven, while the other pump units are disengaged and therefore not driven.
  • the common drive shaft is divided by a plurality of separable couplings into a plurality of drive shaft sections, wherein the individual drive shaft sections each drive at least one of the pump units.
  • the pump units can be selectively engaged or disengaged. In a separation of one of the arranged in the drive shaft clutches, however, all the pump units are disengaged and thus turned off, the kinematically behind the separated Clutch lie while the kinematically before the separate clutch (motor side) lying pump units work.
  • the drive of the wobble piston pump according to the invention is effected by a rotating drive shaft, wherein the pure rotational movement of the drive shaft is converted by a gear in the combined wobble of the wobble piston.
  • the transfer gear in this case controls the piston position of the wobble piston in accordance with a predetermined control curve in dependence on the rotation angle of the drive shaft.
  • control cam has a course that deviates from a sine curve, so that the lifting movement of the wobble piston is not sinusoidal.
  • the control cam of the transfer gear is lift-free in a region around the dead centers of the piston movement, so that the wobble pistons execute only a rotational movement in the lift-free region in order to close or open the inlet or the outlet.
  • the stroke-free region of the piston movement may comprise, for example, a rotational angle range of the planetary gears of at least 5 °, 10 °, 15 °, 20 °, 25 ° or even 30 °. There is even the possibility that the stroke-free rotation angle range up to 60 °.
  • control cam of the transfer gear defines a delivery phase and a filling phase, wherein the wobble piston pump receives the coating agent in the filling phase and expels the absorbed coating agent in the delivery phase again.
  • control cam of the transfer gear is shaped so that the delivery phases of the individual pump units connect with each other in time and without any time overlap in order to achieve a pulsation as low as possible flow.
  • the wobble piston pump outputs a pulsation-free flow.
  • the pulsation of the delivery flow is thus preferably less than 5%, 3% or even less than 2%.
  • control cam of the transfer gear is formed so that the lifting movement of the wobble piston in the filling phase is faster than in the delivery phase.
  • control cam of the transfer gear is shaped so that the lifting movement of the wobble piston in the filling phase is slower than in the delivery phase.
  • control cam of the transfer gear is designed so that the lifting movement of the wobble piston in the filling phase and / or in the delivery phase is carried out with a substantially constant piston speed, which advantageously leads to a correspondingly constant flow rate or filling flow.
  • control cams of the individual pump units differ are, which leads to correspondingly different piston movements.
  • This may be advantageous, for example, if the wobble piston pump according to the invention promotes various components (eg master lacquer and hardener) of a coating agent which must have a specific mixing ratio.
  • a different design of the control curves of the individual pump units in a multi-component pump allows the setting of a specific dynamic mixing process in which, for example, first the first component and then the second component is metered more, which can be realized by a corresponding adjustment of the cams.
  • the mixing ratio of a component A to a component B or a component C can also be adjusted by different piston strokes or different piston diameters.
  • the wobble piston pump has a common coating agent supply line for supplying the coating agent for all pump units.

  • FIG. 16 shows a modification of the control cam according to FIG. 15 .
  • a special feature here is that the slope of the cam during the filling stroke is relatively steep and relatively flat during the delivery stroke. As a result, the wobble piston 31 moves relatively quickly during the filling stroke and relatively slowly during the delivery stroke.
  • FIG. 17 shows a modification of the control cam FIG. 16 ,
  • the control curve during the Be Schollungshubs a relatively flat slope and during the delivery stroke on a relatively large slope.
  • the wobble piston 31 moves relatively slowly during the filling stroke and relatively quickly during the delivery stroke.
  • FIG. 18 shows a multi-component pump 50 according to the invention, which can be used for example in a paint shop, to promote different components of a coating agent separately from each other.
  • the multi-component pump 50 a total of six pump units 51-56, which are each designed as wobble piston pumps.
  • the pump units 51, 55 and 56 serve for metering a first component (for example master lacquer) of the coating agent so that the pump units 51, 55 and 56 are connected in parallel both on the input side and on the output side.
  • This parallel connection in turn has the already mentioned above advantage of smoothing the pulsating flow rates.
  • the mixing ratio of a component A to a component B can be adjusted by different stroke lengths and different piston diameter.
  • the other pump units 52, 53, 54 serve to meter a second component (e.g., hardener) of the coating agent.
  • These pump units 52-54 are therefore interconnected both on the input side and on the output side and therefore operate in parallel, which advantageously leads to a corresponding smoothing of the pulsation.
  • Another feature of the multicomponent pump 50 is the drive through a central sun gear 57.
  • FIG. 19 shows a pump assembly with an electric motor 58 and a plurality of pump units 59-62, which are each connected by separable couplings 63-66 with each other and with the electric motor 58.
  • the pump assembly thus has a drive shaft 67 which is divided into a plurality of shaft sections, wherein the individual shaft sections each drive one of the pump units 59-62.
  • FIG. 20 shows a somewhat modified pump assembly, partially with the pump assembly according to FIG. 19 to avoid repetition, reference is made to the above description, the same reference numerals being used for corresponding details.
  • a special feature of this embodiment is that the drive shaft 67 passes through and the individual pump units 59-62 can each be selectively connected by the associated coupling 63-66 with the drive shaft 67.
  • the Figures 21A-21D show the time course of the flow in a pulsatile Taumelkolbenpumpe with three pump units.
  • the Figures 21A-21C show here the flow rates Q1-Q3 of the individual pump units, while Figure 21D shows the total flow rate Q GES of the wobble piston pump, which results from the superimposition of the flow rates Q1-Q3 of the individual pump units.
  • the flow rates Q1-Q3 of the individual pump units are selected by a suitable design of the respective control curve so that the entire flow rate Q GES is pulsation-free.
  • FIG. 22 shows a schematic representation of a wobble piston pump according to the invention with three pump units 6-8 and a bypass valve 17 between the color input and the color output.
  • the wobble piston pump according to FIG. 22 is largely consistent with the wobble piston pump according to FIG. 1 to avoid repetition, reference is made to the above description, wherein like reference numerals are used for corresponding details.
  • bypass valve 17 is arranged without dead space between the color input and the color output, without additional connection holes are required.
  • FIG. 23 shows a schematic and simplified illustration of a wobble piston pump according to the invention with three pump units 6-8, said wobble piston pump also largely with the wobble piston pump according to FIG. 1 to avoid repetition, reference is made to the above description, the same reference numerals being used for corresponding details.
  • FIGS. 24 and 25 show FIGS. 24 and 25 in that the inlet-side branch lines 9-11 have the same length as the outlet-side branch lines 13-14 have the same length. This is advantageous because the coating agent flowing in via the common coating agent supply line 5 then simultaneously reaches the various pump units 6-8.
