Definitions
- the invention relates to a wobble piston pump for metering a coating agent in a coating system.
- a wobble piston pump is known per se from EP 1 348 487 A1.
- 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 when metering coating agents (for example lacquer) in a coating installation. Rather, when used in a coating system for metering paint, it is desirable for the delivery flow to be as constant as possible in accordance with the desired value.
- the invention is therefore based on the object to provide a correspondingly improved wobble piston pump. This object is achieved by an inventive wobble piston pump according to the main claim.
- the invention comprises the general technical teaching of providing a plurality of pump units in a wobble piston pump, each of which has a cylinder and a wobble piston which, during operation, performs a tumbling movement in the cylinder.
- the individual pump units each require - as the conventional wobble piston pump described above - a pulsating Forderstrom the coating agent.
- the individual pump units are connected on the outlet side to a common pump outlet, so that the blower currents of the individual pump units are superimposed, 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 therefore has three pump units connected in parallel, which represents a good compromise between the requirement for the lowest possible pulsation of the Forderstrom 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, within the scope of the invention, it is also possible to connect a larger or a smaller number of pump units in the wobble piston pump in parallel. For example, 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 tumbling piston pump for the separate promotion of several components (eg parent lacquer and hardener) of the coating composition is suitable.
- 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.
- 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 preferably carried out 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 then arranged in each case, which converts the pure rotary motion of the common drive shaft into the combined tumbling movement (rotational and lifting movement) of the wobble pistons.
- a transfer gear is then arranged in each case, which converts the pure rotary motion of the common drive shaft into the combined tumbling movement (rotational and lifting movement) of the wobble pistons.
- Drive of the wobble piston pump according to the invention is effected by a linearly oscillating drive element.
- a transfer gear must be arranged between the drive element and the individual pump units, which then converts the linear oscillating movement of the common drive element in the combined wobble movement.
- 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, with the individual planetary gears driving one of the pump units in turn.
- 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 above-described variants 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. It has already been mentioned in the introduction that the parallel connection of several pump units in the wobble piston pump according to the invention makes it possible to reduce the pulsation of the delivery flow.
- 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 economic 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 Rialia of the composite are preferably glued together, pressed or screwed.
- silicon nitride, zirconium oxide and aluminum oxide are particularly suitable as ceramic materials for the potting flask.
- 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 pump unit which is to carry out a conveying operation in each case, is 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.
- the drive of the wobble piston pump according to the invention is preferably carried out by a rotating drive shaft, wherein the pure rotational movement of the drive shaft is converted by a transmission into the combined tumbling movement of the wobble pistons.
- 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.
- the control cam of the transfer gear may be sinusoidal, resulting in a corresponding sinusoidal lifting movement of the wobble piston.
- 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 reduction gear is lift-free in a region around the dead centers of the piston movement, so that the wobble pistons execute only one rotational movement in the hub-free region in order to close or close the inlet or the outlet to open.
- 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 ejects the absorbed coating agent again in the delivery phase.
- 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 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 may differ from one another. lent, resulting in 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.
- an inlet-side distributor point is preferably arranged inside the wobble piston pump, from which branch off a plurality of inlet-side branch lines which connect the inlet-side distributor point to the inlet of the individual pump units.
- the inlet-side branch lines between the inlet-side distributor point and the pump units preferably have the same length. This is advantageous because the coating agent flowing in via the common coating agent supply line then also reaches the various pump units at the same time.
- the inlet-side branch lines between the inlet-side distributor point and the pump units preferably have a kink-free course in order to minimize the flow resistance.
- Such a kink-free and continuously curved course of the branch lines can be achieved, for example, by a laser sintering technique or by the so-called rapid prototyping, as described, for example, in DE 10 2008 047 118, so that the content of this document in the present description with respect to the Rapid Prototyping is fully attributable.
- the wobble piston pump has a pump housing, which can be produced by means of rapid prototyping.
- the pump housing can then be reworked on the outside and / or inside.

Therefore, the wobble piston pump according to the invention preferably has a flushing medium inlet for supplying a flushing agent and a flushing agent outlet for returning a flushing agent and a Flushing line leading from the flushing agent inlet through the pump units to the flushing agent outlet.
- the individual pump units are arranged one behind the other along the flushing agent line.
- the advantage of such a series passage of the rinsing agent through the individual pump units with respect to a parallel channel guide is the prevention of clogging of the rinsing agent line.
- the flushing agent would always choose the path of the lowest flow resistance, so that individual flow paths could slowly clog up.
- the rinsing agent line branches into a plurality of parallel line branches, which rinse the individual pump units.
- such a parallel routing of the detergent line is - as mentioned above - less preferred.
- the flushing of the individual pump units is used to flush the piston skirt, which advantageously degrades color leakage along the piston and thus drying of paint behind the piston is prevented, which leads to an improvement in the service life of the wobble piston pump.
- the individual pump units preferably each have at least one piston rod seal, which seals the respective wobble piston, wherein the above-mentioned scavenging medium line is preferably guided through the individual piston rod seals.

- Figure 15 shows a possible course of a control cam 49 of the transfer gear 30, the pure rotational movement in the converts desired wobbling motion. It can be seen that the control cam 49 has a region in which the wobble piston 31 in the region of its dead points ausfart no stroke, which corresponds to Figures 12B and 12D.
- control cam 49 between the dead centers of the wobble piston 31 has an approximately linear region in which the wobble piston 31 thus moves at a constant piston speed, which leads to a constant Forderstrom accordingly.
- FIG. 16 shows a modification of the control curve according to FIG. 15.
- a special feature here is that the gradient of the control curve during the filling stroke is relatively steep and relatively flat during the Forderhubs. As a result, the wobble piston 31 moves relatively slowly during the filling stroke relatively quickly and during the Forderhubs relatively slowly.
- FIG. 17 shows a modification of the control cam from FIG. 16.
- the control curve has a relatively flat gradient during the filling stroke and a relatively large gradient during the Forderhubs.
- the wobble piston 31 moves relatively quickly during the Be Glallungshubs relatively fast and during the Forderhubs.
- FIG. 18 shows a multicomponent pump according to the invention
- the multi-component pump 50 which can be used for example in a paint shop, to demand different components of a coating agent separately.
- 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 (eg stock paint) 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 for dosing a second component (for example 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 special feature of the multicomponent pump 50 is the drive through a central sun gear 57.
- FIG. 19 shows a pump arrangement with an electric motor 58 and a plurality of pump units 59-62, which are each connected to one another or to the electric motor 58 by separable couplings 63-66.
- 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 arrangement, which partially corresponds to the pump arrangement according to FIG. 19, so that reference is made to the above description to avoid repetition, the same reference numerals being used for corresponding details.
- a special feature of this exemplary embodiment is that the drive shaft 67 passes through and the individual pump units 59-62 can each be selectively connected to the drive shaft 67 by the associated coupling 63-66.
- FIGS. 21A-21D show the time profile of the delivery flow in a pulse-action-free wobble piston pump with three pump units.
- FIGS. 21A-21C show the delivery flows Q1-Q3 of the individual pump units, while FIG. 21D shows the total delivery rate Q GES of the wobble piston pump resulting from the superposition of the delivery flows 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.
- Figure 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 largely corresponds to the wobble piston pump according to FIG. 1, so that reference is made to the above description to avoid repetition, the same reference numerals being used for corresponding details.
- FIG. 23 shows a schematic and simplified illustration of a wobble piston pump according to the invention with three pump units 6-8, this wobble piston pump likewise largely matching the wobble piston pump according to FIG. 1, so that reference is made to the above description to avoid repetition, with corresponding details the same reference numerals are used.
- this illustration it is shown how the pistons of the individual pump units 6-8 are flushed via the flushing valve 22 with a flushing agent, wherein the individual pump units 6-8 are flushed serially.
- the pump units 6-8 are thus arranged one behind the other along the detergent line 21.
- FIGS. 24 and 25 show 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 medium feed line 5 then also reaches the various pump units 6-8 simultaneously.
- the invention is not limited to the preferred embodiments described above. Rather, a variety of variants and modifications is possible, which also make use of the inventive idea and therefore fall within the scope.
- the appended subclaims contain independently objects worthy of protection and therefore belong to the subject matter of this application, irrespective of the claims referred to.
- the invention also claims independent of the other features of the invention Protection for the above-described piston rod seal, the flush, the conduit member and the novel wobble piston.
