Each control orifice has a through hole size that is optimized for mix ratio of reagents in the first and second reservoirs. The system can further include a mixer (340), and a plurality of pistons (420a, 420b) that, when activated, drive the reagents in the first and second reservoirs to a static mixer, thereby creating a mixed coating composition of the first and second reagents.

Description

MULTI-COMPONENT CUP, SYSTEM AND METHOD OF USE

BACKGROUND

1. Field

[0001] The present disclosure relates to devices, computer-implemented methods, and systems for providing spray cups for 2K coatings.

2. Background

[0002] Coating manufacturers generally provide coatings as mixed reagents in certain preset volumes that are ready to apply or ready to mix. For example, a coating manufacturer may provide a retail store with several sets of premixed coatings in sealed containers where the end user need apply the coating, or manually add another reagent such as a hardener and then apply the coating to the given object. In some cases, the user can then save the remaining, unused volume for later applications, whereas some mixtures may immediately begin to denature if not applied quickly and hence need to be discarded after completion of a project. In industrial settings, the coating manufacturer may similarly provide the coating mixed, or unmixed, and the industrial user may use various equipment to properly mix the toners and bases before applying the coating. In general, most conventional coatings in the form of basecoats, or color layers can be mixed in advance and later stored without much difficulty.

[0003] Some coatings, such as “2K coatings,” however, need another component, such as a hardener, catalyst, activator, crosslinker, polymerizer, or other similar reactive reagent to be mixed together before application. Once the hardener is applied, there is a fairly limited amount of time, depending on components and mixtures, by which the end user would need to apply the mixed coating. Waste can occur when the needed amounts and mixtures are inaccurate, or if there is delaying the application of the mixture, causing the mixture to spoil.

SUMMARY

[0004] The present disclosure provides systems, apparatus and methods that enable delivery of coating reagents in a correct mix ratio. For example, a coating applicator can include a multi-component cup, and/or one or more additional compartments. The multicomponent cup can include a plurality of reservoirs. The plurality of reservoirs can hold coating reagents or coating reagent containers inserted therein, which, in cooperation with one or more pistons and pumping apparatus can provide an on-demand mixing of the components in the appropriate amounts at the time of applying the coating. [0005] For example, a multi-component cup system for holding and mixing a plurality of coating reagents on demand can include a first reagent reservoir having a first volume, the first reagent reservoir being connected to a first orifice, the first reservoir configured to hold a reactive coating reagent, wherein the reactive coating reagent comprises a crosslinker or catalyst. The multi-component cup can also include a second reagent reservoir having a second volume, the second reagent reservoir being connected to a second orifice that is different from the first orifice, the second reservoir configured to hold a polymer reagent separate from the first reservoir. In addition, the multi-component cup can include a first control orifice and a second control orifice, each of the first or second control orifices communicably connected correspondingly to each of the first and second reagent reservoirs, wherein each control orifice has a through hole size that is optimized for mix ratio of reagents in the first and second reservoirs. Furthermore, the multi-component cup can include a mixer. Still further, the multicomponent cup can include a plurality of pistons that, when activated, drive the reagents in the first and second reservoirs to a static mixer, thereby creating a mixed coating composition of the first and second reagents.

[0006] In addition, a method of applying a multi-component coating can include adding an amount of a first reagent into a first reagent reservoir of a multi-component cup, wherein the first reservoir is coupled with a first control orifice to be applied to the first reagent reservoir. The first control orifice provides a volumetric flow. The method can also include adding an amount of a second reagent into a second reagent reservoir of a multi-component cup, wherein the second reservoir is coupled with a second control orifice to be applied to the second reagent reservoir. The second control orifice provides a volumetric flow. In addition, the method can include activating a pressure supply, wherein activation causes the pressure supply to supply a pressurized fluid to a lower nozzle of each of the first and second reagent reservoirs. Furthermore, the method can include driving a piston in the first reagent reservoir and piston in the second reagent reservoir with the pressurized gas to pump corresponding reagent outward toward the corresponding first or second control orifice. The first and second orifices cause different amounts of first reagent to be mixed with second reagent to form a reagent mixture consistent with a predetermined mix ratio.

DETAILED DESCRIPTION

[0020] The present disclosure provides systems, apparatus and methods that enable delivery of coating reagents in a correct mix ratio. For example, a coating applicator can include a multi-component cup, and/or one or more additional compartments. The multicomponent cup can include a plurality of reservoirs. The plurality of reservoirs can hold coating reagents or coating reagent containers inserted therein, which, in cooperation with one or more pistons and pumping apparatus can provide an on-demand mixing of the components in the appropriate amounts at the time of applying the coating.

[0021] As will be understood more fully herein from the following specification and claims, the one or more multi-component cups can enable controlled mixture, and precise application to an object to be coated. This can enable the application of highly tailored coating reagents so that they may be delivered in an essentially on-demand format, and with a wide range of available attributes in the finished product. By way of explanation, a coating system, such as a clearcoat or other coating system, may comprise a plurality of different types of resin/polymer reagents with favorable stability. Resin reagents, for example, can contain one or more unique resins, along with additives such as catalysts, ultra-violet absorbers (UVA) / or Hindered Amine Light Stabilizers (HALs) additives, leveling agents, and solvents to reach viscosity around 500 centipoise (cP). Resin reagents can also contain pigments or fillers. The several unique resins can include a wide range of resins with differing polymer properties, including differing by Mw, Tg, functionality and reactivity. A dispensing apparatus (e.g., 110, Figure 1) can select the most appropriate resin/polymer reagents for a given situation, and provide the resin reagents in customized volumes/amounts and mixtures, as needed for a given operating condition.

[0022] In addition, the present disclosure can include providing, through a multicomponent cup, a wide range of reagents for use with a polymer reagent, such as crosslinker reagents in the case of coatings in the form of clearcoats. Crosslinker reagents may contain unique types of crosslinkers along with solvents in order to similarly reach viscosities around 500 cP, or other desired attributes of application or finish. Several unique crosslinkers may be utilized to cover wide ranges of crosslinker properties, also including Mw, Tg, functionality and reactivity. A dispensing apparatus (e.g., 110, Figure 1) can provide the crosslinker reagents in various volumes and mix ratios, along with any other additives. A dispensing apparatus (e.g., 110), discussed more fully herein, can hold or store physical containers of various types of crosslinker reagents, and dispense the crosslinkers in the relevant amounts needed.

[0023] Still further, the present disclosure can provide for the use through a multicomponent cup, a number of catalyst reagents and differing types thereof. Each catalyst reagent, in turn, may comprise a solution further comprising one or more catalysts, catalyst modulators, inhibitors and solvents. The concentration of catalyst in the reagents may range from 1% to 100%. Yet still further, the present disclosure can provide a number of reducer reagents, and multiple different types thereof. Each reducer reagent likewise may comprise one or more solvents with a specific range of physical properties, such as relative evaporation rate, and Hansen solubility parameters.

[0024] In one example, an end user can store or otherwise hold the various catalyst or reducer reagents in various physical containers, which may comprise sealed containers in various different volumes that the dispenser accesses to dispense certain amounts to an enduser. The user can then determine an appropriate amount to mix two different components and in a particular ratio through a coating (or spray) applicator. This determination may be provided by mix instructions provided with the given reagents. A user can then select various apparatus to ensure that the reagents are mixed and applied on-demand in the correct ratios provided from the instructions, thereby maximizing productivity while minimizing waste.

[0025] As an initial matter, for purposes of understanding aspects of the present disclosure, it will be understood herein that the articles “a” or “an” can include “one or more.” That is, although the disclosure may be presented in terms of ‘a’ feature, ‘an’ element, and the like, one or more of any of these components or other recited components can be used according to the present disclosure.

[0026] Turning now to the Figures, Figure 1 illustrates a schematic of a system 100 for using a multi-component cup to apply coating reagents to an object, in accordance with the present disclosure. In particular, Figure 1 shows that system 100 comprises a coating applicator 150, which may be used to apply multiple reagents in mixed form to an object 140 (e.g., the illustrated automobile) in a coating application area 160. The coating application area 160 may comprise, for example, a paint booth or other suitable application location. In the coating application area 160, the spray applicator 150 (e.g., whether robotic, or operated by a human user) can apply, or mix and apply, a given set of coating reagents (e.g., from reagent containers 133, 135) to a given object, such as the illustrated vehicle 140. In addition, one will appreciate that the illustrated vehicle 140 is but one type of object that may be coated or painted in the coating application area 160. The coating applicator 150 may, for example, spray other types of objects, or parts thereof, as needed, including body panels, original parts, replacement parts, and the like. Other objects may include boats, bicycles, industrial, commercial, or other residential equipment, doors, walls, and parts or portions thereof. Accordingly, both the terms object and vehicle will be understood to be broadly encompassing of any physical object to be coated.

[0027] In addition, the illustrated reagent containers 133 and 135 can, in some examples, be placed directly in a multi-component cup, or “container,’" (e.g., any of 200a-200f, Fig 3A-3B), which enables on-demand, and precise mixture of the reagents at application. For example, the coating applicator 150 can comprise an e-coat apparatus, a coating atomizer, a spray gun, or other form of coating application device. The physical containers 133, 135, etc., in turn, can be configured for direct application to the coating applicator 150. For example, as understood more fully with respect to Figures 2A through 6, the physical containers 133, 135 may comprise a particular physical connection interface (e.g., lid 120a/b, or other interface within an upper removable lid), that interfaces physically and directly with a corresponding physical interface of the multi-component cup, or a lid thereof, and is then attached to the spray applicator 150. The precise physical interconnection may be employed in a number of different ways between the coating applicator 150 and the physical containers 133, 135, and as discussed more fully below.

[0028] In general, the physical containers 133, 135 shown in Figure 1 are abstract representations, and may comprise a wide range of shapes and configurations. For example, while Figure 1 shows a simple, circular shaped container with lid 120a, 120b, other Figures herein (e.g., Figures 4A and 4B) illustrate other lid shapes that can be used to connect the physical containers 133, 135 for reagent delivery. In either case, the physical containers 133, 135 may be understood to have a particularly-shaped lid that directly connects or overlaps with an upper portion of the given reagent container 133, 135, or enables attachment (e.g., press, screw, snap-fit, etc.) with one or more channels, where the one or more channels allow reagent from the reagent reservoirs (e.g., 310a-b) to flow therein.

[0029] In still other cases, the user may manually release a lid of the physical container 133, 135, and simply pour the particular reagent from the physical containers 133, 135 directly into a given cup (or reservoir therein) attached to the coating applicator 150, such as multi- component cup 200a (Figures 2C, 3A, 4A, etc.) In still further cases, the reagent containers 133, 135 may be attached directly to an interface of the spray applicator 150 (Figure 4A, 5A). Similarly, the user may open and manually mix the containers in accordance with the provided mix instructions, and then provide the already mixed materials into an optional use reservoir, which may be used as a mixture reservoir (e.g., Fig. 3B, 300) accessed by the coating applicator 150.

[0030] As understood more fully herein, a variety of components can be employed to ensure that the given reagents flow in a particular direction and in a particular volume to ensure precise mixture and delivery. In addition, as further understood herein, the reagents may be provided from the multi-component cup 200(a-f) through a gravity fed mechanism, or even through a pressurized system. One will understand in light of the present disclosure and claims that the particular driving mechanisms are generally interchangeable, and that the precise mixing ratios can be accomplished in most cases by virtue of the channels and orifices used in light with the flow of the reagent (or reagent mixtures). In still further additional or alternative cases, precise mixing can be accomplished at least in part by variable pressure flow, such as by differentially applying pressure in one reagent reservoir relative to another, and thus applying different amounts (and/or at different intervals) of reagent into the mixture reservoir.

[0031] Continuing with the Figures, Figures 2A and 2B provide conceptual illustrations of fluid/reagent flow using a generalized, multi-component cup 200 that employs a pressurized drive system (i.e., use of pressurized fluid and pistons). In this example, multi-component cup 200 (or “2K cup’') comprises a plurality of reagent reservoirs, namely reagent reservoirs 210a, 210b, which hold various coating reagents in an unmixed state, and sealed from each other to prevent cross-reaction or contamination. Figures 2A and 2B further show that the exemplary multi-component cup 200 can comprise lids 220a, and 220b, that, in turn, are coupled with a conduit assembly 260. Figure 2A further shows that conduit assembly 260 may contain various channels, orifices, and other components, as needed (e.g., an activatable solenoid), which, in turn, connects to corresponding lids 220a, 220b that seal the reagents from cross-contamination or mixture.

[0032] For example, Figure 2A shows that lids 220a, 220b may connect directly to a corresponding reservoir 210a, 210b wall, or directly to a physical container (e.g., 133, 135) inserted in the given reservoir 210a, 210b. The conduit assembly 260, in turn, may comprise an upper nozzle lid 220a, and 220b, as well as control orifices 240a, 240b. Figures 2A and 2B further illustrate that the reservoirs 210a, 210b comprise or are otherwise coupled to lower nozzle interfaces 400a, 400b. The lower nozzle interfaces 400a, 400b may be used to connect the multi-component cup to one or more pressurized fluid (e.g., pressurized air) sources. Figure 2B shows that the reservoirs 210a, 210b may comprise various pistons 420a, 420b. One will appreciate that the view of Figure 2B omits the lower nozzle interfaces 400a, 400b for illustrative convenience. Nevertheless, the pistons 420a, 420b will be understood as being driven by the pressurized fluid provided via the lower nozzle interfaces 400a, 400b shown in Figure 2A. Figure 2B further illustrates that the lid 220a of the multi-component cup of Figure 2A is closed, enabling a direct connection of the conduit assembly 260 with the reagent reservoirs 210a, 210b.

[0033] In operation of a pressurized form of the device, a user may connect pressurized fluid channels (not shown) to the lower nozzles 400a, 400b. Upon activating a pressurized fluid device, pressurized fluid can flow up through the lower nozzle interfaces 400a, 400b, driving the pistons 420a, and 420b. The activated pistons 420a and 420b, in turn, provide pressure that drives corresponding coating reagent in the given reservoirs 210a, 210b up through the conduit assembly 260, and into the illustrated mixing conduit 320a. The pressurized fluid delivery can be configured to apply different amounts of pressure through the given pistons to at least partly adjust volumetric flow from one reservoir or another to the coating applicator 150, via the mixing conduit. In the mixing conduit 320a, the reagents swirl around a mixer 340, which may comprise a moving or static mixer. In the illustrated case, the mixer 340 is a static mixer, and may optionally be replaceable or disposable if desired to reuse the given cup. The mixed reagents can then flow directly to a coating applicator 150, or may be driven into an optional use reservoir (e.g., 300, Fig. 3B), and ultimately out of a spray nozzle and onto object 140.

[0034] In an alternative example, the conduit assembly 260 can be configured for gravimetric delivery. In such a case, the conduit assembly 260 can be positioned beneath the reservoirs 210a, 210b, such as in connection with lower nozzles 400a, 400b. When a user activates the coating applicator 150, a valve (not shown) in the lower nozzles 400a, 400b can be opened, allowing reagent to flow gravimetrically down through the conduit assembly, through the orifices 240a, 240b. In such an example, the mixing conduit 320a and static mixer 340 may be shortened or positioned alternatively below the lower nozzles 400a, 400b, and in line with the downward flow of reagent. In still further alternatives, the mixing conduit 320a and static mixer 340 may be eliminated entirely, such that only the orifices 240a and 240b differentiate the amount of reagent being dropped into the coating applicator 150 at any given time. Between the use of the orifices 240a, 240b, pistons 420a, 420b, lower nozzles 400a, 400b, mixing conduit 320a and static mixer 340, there are multiple additive and alternative mechanisms for delivering fluid to coating applicator 150 either with applied pressure, gravimetric flow, and combinations thereof.

[0035] Figure 3A illustrates various alternate containers (e.g., 200a, 200b, 200c, 200d) that can be used in different formats for receiving the dispensed reagents, particularly various iterations of a multi-component cup (or “2K cup”). Figure 3A further shows that the alternate container/2K cup formats 200a-200b can include by way merely of example circular or cylindrical format containers 200a-b with internal compartment divisions, while containers 200c-200d show square or rectangular containers with internal compartment divisions. Thus, as previously discussed, the compartment divisions in the various multi-component cups or containers 200a-200d (or containers within containers) can be used to separate reactive components or other types of reagents that may more quickly denature upon mixing. In other cases, the given containers (whether single or multiple compartment containers) may contain a sealable bladder for one of the compartments, while the others remain open to air. In still other cases, the containers may include lids (e.g., lid 120a/b, 220a/b) that are specifically shaped to preserve and seal containers or compartments within the containers 200a-200d. One will appreciate that other shapes and compartment configurations of 2K cups may be used in accordance with the present disclosure.

[0036] Figure 3B illustrates alternate orientations of one particular multi-component cup 200a. For example, much as shown in Figures 2A-2B, Figure 3B shows that the multicomponent, (i.e., 2K) cup 200a can comprise a housing or body 305, along with multiple internal compartments or reservoirs 300, 310a, 310b, that enable coating reagent separation in some instances, and holding of coating reagent mixtures in others. Accordingly, Figure 3B shows that 2K cup can comprise first and second reagent reservoirs 310a, 310b arranged beside an optional use reservoir 300. Optional use reservoir 300 may comprise a mixture reservoir for holding the mixed reagents just before application, or may house other mechanical and/or electrical components needed to serve the operations described herein. Figure 3B further shows that the 2K cup 200a can comprise an upper, mixing conduit 320, and may optionally also comprise an optional lower, release conduit 330. In the case where the reservoir 300 comprises such an optional use reservoir, the lower, release conduit 300 may enables reagent to flow from the mixing conduit 320 in a mixed form (via the static mixer 340) into the optional use reservoir 300 for subsequent delivery.

[0037] In one example, the optional use reservoir 300 can be used to provide an appropriate “buffer” for holding mixed reagents from the reservoirs 310a, 310b. For example, a user may desire to provide a consistent pressure load to the coating applicator 150. With continuous or repeat use of any given multi-component cup 200 (e.g., 200a-200f), the reagents may adhere with time to the walls of the given cup 200, or other areas in the conduit assembly 260, which may slow the reagent flow, and/or otherwise reduce the pressure at which the mixed reagents can be applied to the coating applicator 150. Having an optional use reservoir 300 may allow mixed reagents to be maintained to enable a consistent flow mixed reagent to the coating applicator 150 directly from the optional use reservoir 300 to the coating applicator, and in a consistent pressure that does not rely on variable, declining (with time) pressure through the reagent reservoirs 210a, 210b and conduit assembly 260. In one example, the pressure of reagent to be delivered to the coating applicator is between from 5 psi to 50 psi, preferably from 15 psi to 40 psi, preferably from 25 psi to 35 psi, or more preferably from 30 psi to 32 psi. The optional use reservoir 300 can thus provide a buffer that enables consistent flow of reagent to the coating applicator 150 at a consistent pressure.

[0038] As used herein, the term “hold” in the context of the multi-component cup 200(a-e) means that the given reservoir 310a, 310b, 310c, 310d, etc. may at least temporarily store a coating reagent, whether within a cannister (whether a hard container, a flexible bladder, etc.) or as raw reagent poured directly therein. Holding in this case means that the reagent poured therein is maintained without lateral spilling outside of the cup, or outside of the walls provided by the cup frame 305. In other words, the reservoirs can retain a cup or bladder of reagent inserted directly into the reservoir or maintain the fluid form poured directly into the given reservoir without leaking or spilling outside the cup. Furthermore, the term “sealing” or providing a “seal” means that the reagents are maintained sufficiently separate before mixing so that they do not inadvertently mix without passing through the given orifices disclosed herein. This may be done either by use of the given reagent containers (133, 135, 133a, 135a), or by a combination of the lateral walls of the multi-component cup body 305 and upper lid 500, discussed more fully herein. Thus, the terms “hold” or “seal” and corresponding gerund forms refer to maintaining the reagents in an intended form (i.e., intended to be separate, or in an intentionally mixed state) without spillage or other inadvertent mixing between reservoirs. In other words, the multi-component cup can hold or maintain an intended volume of the mixed reagents in reservoir 300 after mixing, and maintain a seal of the mixed or unmixed form of the reagents from spillage or leakage between reservoirs, except when or where specifically intended.

[0039] Referring again to the Figures, in one method of operation, the reservoirs 310a, 310b may receive reagent by the user positioning the given reagent containers within the reservoirs 310a, 310b, or may pour in the content of the reagent containers 133, 135 directly into the reagent reservoirs 310(a-b). As understood more fully herein, channels connected to the reagent containers 133, 135 can extend into the mixing conduit 320, which may further comprise a mixer 340 positioned therein, such as a static mixer. As implied by name, a static mixer does not necessarily need to rotate, and generally will not. One will appreciate that the disclosure is not so limited, however, and that the 2K cup may also employ a rotating mixer that is driven by one or more elements or drivers extending, for example, from the coating applicator 150 / spray gun (Figure 1, 4A). In any event, and as further understood in Figures 4A-6, the coating reagents can be pumped through a channel (e.g., Figure 2A) and into mixture conduit 320, whereby the coating reagents will essentially swirl about the given mixer 340 until exiting the mixer through lower, release conduit 330 and into the optional use reservoir 300. The mixed together reagents can then remain in the optional use reservoir 300 until passed through the coating applicator 150 gun/sprayer on demand.

[0040] Figure 4A illustrates additional details, and orientations, including assembled and exploded views of the multi-component cup 200a of Figure 3B. For example, Figure 4A shows that the 2K cup 200a can comprise multiple additional elements, such as the previously described lower nozzle interfaces 400a, 400b, which may receive an end of a given coating reagent container 133a, 135b. That is, the lower end of the reagent containers 133a, 135a can be configured to mate with, or otherwise rotate into, a well of the lower nozzle interface 400a, 400b. The internal well of the lower nozzle interfaces 400a, 400b may be threaded in a way that reciprocally locks in the lower edge of the reagent container 133a, 135a.

[0041] A user can connect the lower nozzle interfaces 400a, 400b, in turn, to one or more pressure supply conduits, such as a channel or other piping coupled to a pressurized air supply. In a gravimetric delivery example, the lower nozzles 400a, 400b may connect directly to the coating applicator 150, or to an alternately arranged conduit assembly 260 and/or mixing conduit 320a, etc. as previously described. In the present example, however, Figures 4 A and 4B further show that the reagent containers 133a, 135a further comprise one or more pistons 420. Alternatively, the 2K cup may be assembled with the lower nozzle interfaces 400a, 400b and pistons 420 within each reservoir, instead of having the pistons 420 inserted within a reagent container 133a, 135a. For example, in cases in which the end user pours reagent directly into the reagent reservoirs 310a, 310b, instead of using reagent containers 133a, 135a. In either case, pressurized fluid can be driven through nozzles 400a, 400b directly against the pistons 420 in both reservoirs 310a, 310b (or directly against the pistons within the given reagent containers 133a, 133b), thereby driving reagent fluid upward / outward. [0042] Figures 4A and 4B further illustrate various upper nozzles 430a, 430b, which serve as the points of delivery from the reagent containers 430a, 430b into another attached channel (Figure 5A). In addition, Figure 4B illustrates an assembled view of the reagent container 133a/135a, in which a user has added a volumetric control orifice 440 (or “control orifice”). In general, the control orifices 440(a/b) can provide flow rate limits or adjustments to the flow of a given reagent out of the reagent container 430a/430b. Thus, the control orifices 440 can enable a user to govern relative amounts that are pumped out of the reagent container, and thus assist creating a more precise mixture, thus removing error from the end user. That is, the control orifices 440 may be optimized with differentially sized through holes to limit or enhance reagent flow consistent with the reagent viscosity. The control orifice 440 can be attached to the upper nozzle 430(a/b) through various mechanisms, such as a push to connect, or threaded mechanism.

[0043] Figure 4C illustrates various perspective views of an exemplary control orifice 440(a-b). In particular, Figure 4C illustrates that an exemplary control orifice 440 can comprise a threaded end 445 and an opposing end 450, which may comprise a push-to-connect fitting. The bottom view shows that the threaded end 445 of control orifice 440 can comprise a through hole (orifice) 460a. Figure 4C further shows that the through hole continues into the top end, such as in the top view, showing through hole 460b. A manufacturer can create different control orifices with differently sized through holes to correspond with desired flow rates, making the through hole/orifice 460(a/b) wider or smaller for different applications. As previously mentioned, this can include different reagent viscosity considerations, as well as relative amounts to be delivered to mixing conduit 320, over and around the mixer 340 (Figure 4D), and ultimately into the optional use reservoir 300.

[0044] For example, if the resulting mixture is to be predominantly one coating reagent (polymer) compared to another (crosslinker), the control orifice (e.g., 440a) attached to the coating reagent container containing polymer (e.g., 133a) may contain a larger through hole than that of the control orifice (e.g., 440b) connected to the coating reagent container (e.g., 135a) containing crosslinker, or vice versa, as needed. The manufacturer may additionally adjust the delivery and mixture of such amounts by varying the amount of pressure applied to the pistons 420 in each given reagent reservoir 310a, 310b. In some cases, the multi-component cup/system may be configured with multiple points of control in order to moderate/adjust delivery, flow, and amounts of reagent into the optional use reservoir 300.

[0045] Figures 5A and 5B illustrate alternative conceptualized views of a 2K cup, namely cup 200a used with or without lid 500. For example Figure 5A shows the example embodiments of Figures 4 A and 4B, in which the end user employs coating reagent containers 133a, 135b within reservoirs 310a, 310b. Figure 5A shows the various components in an expanded form for purposes of better illustrating the direction of fluid flow, although one will appreciate that a desirable form factor may include miniaturizing such components to fit neatly within the 2K cup lid 500, such as shown in Figure 5B. As previously described, an end user may employ a gravity-based delivery (as noted above), or pressurized delivery. With a pressurized delivery, the user may employ a pressure mechanism (e.g., pressurized air through lower nozzle interfaces 400a, 400b) to push reagent from out of the reagent reservoirs 310a, 310b. The applied pressure drives the coating reagent through the respective control orifices 440a, 440b to thereby deliver differential amounts (e.g., volume) of coating reagent at any given moment in time. For example, the applied pressure drives the respective reagents through a series of additional conduits, such as one or more conduits 510, 530, before passing through the mixing conduit 320. The pressure further drives the coating reagents through and around the mixer 340 (e.g., static mixer, Fig. 4D) until exiting into the optional use reservoir 300.

[0046] In additional or alternative configurations, the conduit 510 and 530 may be connected in line with a solenoid 520. The solenoid may be electronically connected to the spray gun 150, and/or to other electronics that may be stored in the optional use reservoir 300. In general, the solenoid 520 can be used to further moderate amounts of coating reagent being driven into the mixing conduit 320. For example, the solenoid 520 may be connected to one or more sensors proximate to or within the optional use reservoir 300 to thereby open or close passage between the conduits 510, 530. In additional or alternative examples, the solenoid 520 may be replaced with a manual valve, or a pneumatic valve for similar purposes. However configured, the solenoid/valve can help to maintain proper amounts of mixed coating within reservoir 300, such as when the volume is too low or too high.

[0047] Figure 5B illustrates a similar example (albeit with miniaturized conduit assembly), and with the further exception that the 2K cup further employs a sealing lid 500. The sealing lid 500 may be completely removable, or be further attached via a hinge (not shown). The example in Figure 5B may be particularly useful for examples in which the user pours coating reagent directly into the reservoirs 310a, 310b without the use of reagent containers 133a, 135a. In general, the illustrated examples herein show examples of reagent containers exceeding the size of the 2K cup body 305 merely for purposes of convenience in description. The 2K cup 200a and reagent containers 133a, 135a may be particularly sized to fit in a flush manner as in Figure 5B (compare with Figure 4A), or the user may employ the 2K cup with no lid for longer containers. Of course, a manufacturer may elect to deploy the previously illustrated, exemplary conduit and piping 510, 530 of Figure 5A in a more compact form within the lid 500 and body 305 of Figure 5B.

Example 1

[0048] The following example illustrates the effect of differences in orifice size (e.g., through-holes 460a/460b) of a given nozzle (e.g., 400a/400b) on mix ratio. A prototype 2K cup (e.g., 200) was assembled utilizing commercially available materials:

[0049] To quantify effect of orifice size on the mixing ratio of a two-component paint, a two-component mixture comprising a “Part A’" and a “Part B” was prepared using DC4000 and DCH3O85 purchased from PPG INDUSTRIES, INC. The viscosities of the two components were measured by a flow cup conforming to “Deutsches Institut fur Normung" (i.e., German institute for standardization) 4 standard, or “DIN 4 standard.” Part A was prepared by adding 1g of DMD1627, a blue tint available from PPG Industries, to 100 g of DC4000. Part B was prepared by adding 0.25 g of Quinoline Yellow powder (available from SIGMA ALDRICH) to 100 g of DCH3085. The operator mixed the solution for 60 minutes to dissolve the tint, to thereby provide Part B.

[0050] Two 2.5 oz Optimum Cartridges with 0.25 inch NPT (i.e., “National Pipe Thread”) outlet from NORDSON EFD were filled with either part A or part B as described above. Both cartridges were connected to an upstream air source. Part B was connected to a downstream flow control orifice of 0.02 inch diameter available from MCMASTER-CARR (part number 6349T13). Part A was connected to flow control orifices of various sizes to create the desired mix ratio. Both flow control devices were connected to the same downstream static mixer of 0.5 cm inner diameter, 10 cm length, and 25 mixing baffles available from (NORDSON EFD). The static mixer was connected to a downstream 20mL vial to collect mixed material. Mixing began when the cartridges were placed under 30 psi of pressure. When the vial was half full it was switched for a new vial. The material in the first and last vials were discarded to remove the influence of artifacts during start up and shut down of the mixing.

[0051] Material from each vial was applied to a 7B LENETA CHART using an #8 wire-wound bar. The applied material was cured at 60 °C for 30 minutes. The color of the applied material was measured using a BYK-MAC Multiangle Spectrophotometer. The B* value at 100° of the prototype mixed material was compared to the B* value of Part A and Part B hand mixed at various ratios (Table 1). This particular value (B*) of the CIELAB color space was taken since the B* value was most sensitive to shifts on the blue-yellow axis, which changes occur as the mix ratio changes.

Table 1

Table2

[0052] In light of the data in Tables 1 and 2, one can estimate the orifice size and ratio for any desired mix ratio for a particular paint system using the following equation: Mix ratio (A:B) = -4.176+( Part A flow control orifice diameter inches) * 282.5, given a constant Part B flow control orifice size of 0.02 inches. Table 3, below, provides calculated values using this equation.

Table 3

[0053] The present disclosure can also be described in terms of one or more methods comprising a set of acts for accomplishing a particular result. For example, Figure 6 illustrates a flowchart of a series of acts in a method of using a multi-component cup. The acts of Figure 6 are described below with the elements of Figures 1-2B.

[0054] For example, Figure 6 shows that a method 600 of using a multi-component cup can comprise an act 610 of adding a first reagent to a reservoir. Act 610 includes adding an amount of a first reagent into a first reagent reservoir of a multi-component cup, wherein the first reservoir is coupled with a first control orifice to be applied to the first reagent reservoir, wherein the first control orifice provides a volumetric flow. For example, a user can fill reagent reservoir 310a of multi-component cup 200a with a reactive reagent (or alternatively a polymer reagent), for use in creating a clearcoat. This can be accomplished by directly dispensing the reagent into reservoir 310a (e.g., Figure 2C), or by inserting one of either reagent container 133a or 135a into the reservoir 310a. Moreover, the control orifice such as 440a or 440b may be applied directly to an upper nozzle of reagent container 133a or 135a based on a determined viscosity of the reagent and a desired relative amount of reagent to be mixed with the reagent in the other reagent reservoir. Along these lines, with reagents is similar viscosity, the user may determine to use supply a reagent where control orifice 440 with a relatively larger through-hole 460a/460b is used to add larger amounts of the given reagent into a mixture, or a control orifice with a smaller through-hole (e.g., half the diameter) of another control orifice through-hole to mix in lower amounts of the same reagent. Similarly, the user may determine to match through-hole sizes of various control orifices to provide even amounts of reagent in the mixture.

[0055] Figure 6 also shows that method 600 can comprise an act 620 of adding a second reagent to a reservoir. Act 620 includes adding an amount of a second reagent into a second reagent reservoir of a multi-component cup, wherein the second reservoir is coupled with a second control orifice to be applied to the second reagent reservoir, wherein the second control orifice provides a volumetric flow. Similar to act 610, the user can fill reagent reservoir 310b of multi-component cup 200a with a polymer reagent (or alternatively a reactive reagent if supplying polymer reagent in the first reservoir) for mixing with the reactive reagent, such as a crosslinker, hardener, or other catalyst reagent. The user can dispense the polymer reagent directly into the reagent reservoir 310b (e.g., Figure 2C), or by inserting the other of reagent container 133a or 135a into reagent reservoir 310b. As discussed above for act 610, the user may similarly determine to match a given reagent with a control orifice 440 of a particular through-hole size that is comparatively smaller, larger, or similar to the first control orifice in order to help govern the amount of given reagents in the intended mixture. Naturally, the user may desire to match the through-hole size of the second control orifice to the viscosity of the reagent in the second reagent reservoir 310b.

[0056] Furthermore, Figure 6 shows that method 600 comprises an act 630 of activating a pressure supply. Act 630 includes activating a pressure supply, wherein activation causes the pressure supply to supply a pressurized gas to a lower nozzle of each of the first and second reagent reservoirs. For example, as previously described, the user can activate a pressure supply, such as by pulling the trigger on coating applicator 150. The pressure supply may then activated deliver a pressurized fluid (e.g., pressurized air or other gas) through lower nozzles 400a, 400b.

[0057] Along these lines, Figure 6 shows that method 600 still further comprises an act 640 of driving a piston in the first and second reservoirs. Act 640 includes driving a piston in the first reagent reservoir and piston in the second reagent reservoir with the pressurized gas to pump corresponding reagent outward toward the corresponding first or second control orifice. For example, in response to the pressurized fluid activated through step 630, the pressurized fluid may be applied to the pistons 420, such as via separate trigger or gripping mechanism on coating apparatus 150. This triggering can in turn drives pistons 420 positioned in the reservoirs 310a, 310b. The driving of the pistons 420 pushes reagent out of the reservoirs 310a, 310b through the first and second control orifices, and ultimately into the mixing conduit 320. Thus, the first and second orifices cause different amounts of first reagent to be mixed with second reagent to form a reagent mixture consistent with a predetermined mix ratio.

[0058] Accordingly, the present disclosure provides a number of systems, components, compositions, and methods that enable a number of advantages over the present art. For example, when customers need to repair and paint cars, the proper ready-to-use or ready-to- mix product is provided to them on-demand. This can allow coating applicators to focus on spraying paint or other coating formulations without an accompanying need to make precise selections and mix them in a precise ratio. This simplifies the work process for end-users and addresses several conventional difficulties. Because a coating manufacturer providing the solutions outlined herein are providing not only paint, but also services that are beneficial to end-users, coating manufacturers can expand the way they connect with end-users. The connection can be facilitated by delivering ready-to-use products that best fit the end-user’ s needs on-demand. That is, both large and small shops can order reagents on demand, and apply them precisely as needed in a timely fashion without error.

[0059] As previously noted, the present disclosure can also be described in terms of various alternate configurations. For example, in one configuration, the reagent delivery is gravity based, meaning that the reagents flow from the reagent reservoir downward through the conduit assembly 260, which includes appropriately situated orifices, channels, and potentially also one or more manual or otherwise activatable valves for delivering precise amounts of reagents to the coating applicator. In another example, the reagent delivery is pressurized, in which case the system may employ one or more pistons (or other relevant driving mechanisms) that apply pressure from the reagent reservoirs 210/310 through the conduit assembly 260, through a static mixer and/or mixing conduit and into the coating applicator 150. Optionally, the fluid in either case can be further delivered to an optional use reservoir 300. In either case, at least on advantage of these various examples is the ability to provide precise amounts of reagent in precise ratios on-demand to a coating applicator. Moreover, because the multi-component cup can be washed out and cleaned, and/or since the static mixer may be removed and disposed, the multi-component cup(s) described herein provide further opportunities to minimize waste. Still further, because the given reagents can be mixed on-demand and applied on-demand, components and systems of the present disclosure allow for a user to minimize reagent waste.

The described examples are to be considered in all respects only as illustrative and not restrictive.
