The present disclosure relates generally to a fluid applicator. More particularly, the present disclosure relates to a fluid applicator and a fluid application system for applying a fluid to a substrate.
Rollers are used to apply paints and other liquids to a desired surface. Rollers hold a liquid on the outer surface or nap of the roller until it is desired to apply such liquids. As a roller is placed in contact with a substrate, the liquid is transferred from the outside of the roller to the contacted substrate. However, when the substrate is channeled, corrugated, or ribbed such surface irregularities prevent the surface of the roller from contacting the substrate to be coated.
For example, a roof panel that is formed with ribs and channels will have a surface that is undulated. As a conventional roller is used with such a surface, the liquid cannot be adequately transferred from the roller to the substrate because the roller cannot contact all of the areas of the substrate or roof panel. The areas of the substrate that are not contacted by the roller do not receive the liquid. This results in many areas of the substrate being uncovered by the liquid.
To attempt to coat these uncovered areas of the substrate, the roller must be placed in awkward orientations to try to transfer the coating from the roller to the substrate. This method of application makes the process of coating a channeled surface very difficult. This process is time consuming and often it is impossible to reach all of the surfaces to be coated. Furthermore, the person maneuvering the roller is placed in danger as they attempt to orient the roller to the channeled surface.
An additional challenge that arises when applying fluids to a desired surface includes providing a continual supply of the fluid to a roller, at the application location, that will be used to transfer the fluid to the desired surface. Carrying, moving, or transporting a reservoir of fluid to an application location is often not practical.
The present disclosure provides a coating applicator that applies a coating or liquid to a variety of different substrates having different contoured surfaces. The present disclosure provides a coating applicator that is able to reach, contact, and cover the entirety of a contoured substrate.

In one embodiment, the fluid applicator 122 for applying the fluid F to the substrate 100 is removably attachable to the carrier 200 and includes a body 130. Referring to
Referring to
The fluid dispensing portion 124 provides a mechanism for applying and supplying the fluid F to the fluid applicator 122. In one embodiment, the fluid dispensing portion 124 is removably attachable to the carrier 200 and includes a plurality of ports or apertures 140. For example, in one embodiment, the fluid dispensing portion 124 includes a dispensing rod or tube 142 defining a plurality of apertures 140. In this manner, a fluid is provided through the fluid dispensing portion 124 and out the plurality of apertures 140 thereby applying and supplying the fluid F to a fluid applicator 122.
Referring to
Referring to
If an outlet port of a dispensing tube is placed in close proximity or touching a roller, then the nap, fibers, or bristles and the fluid application system negatively impact the performance of the roller. The fluid needs to flow freely onto the roller without inhibiting the rollers performance. Also, when the outlet port of a dispensing tube is placed in close proximity or touching a roller, the nap or fibers obstruct the ports thereby clogging and blocking the ports. Residue on the roller can begin to cure or dry out so the supply line will also dry out thus stopping the flow of a fluid from the dispensing tube to the roller.
In an exemplary embodiment of the present disclosure, the fluid dispensing portion 124 is approximately at least ¼ of an inch away from the surface of the fluid applicator 122 but not more than approximately 5 inches. When the dispensing portions are a distance of greater than approximately 5 inches the stream of the fluid can be easily disrupted by the moving action of the application system as it applies the fluid to the substrate. A bump in the substrate, for instance, can cause the stream to flow errantly. Additionally, when the distance is greater than approximately 5 inches then foreign objects such as dust can contaminate the fluid. Long streams are also susceptible to disruption by wind causing the stream to miss the fluid applicator.
Other conventional methods include filling the inside of a roller or brush. The fluid then travels out of openings in the roller to the roller nap or bristles. These conventional methods have several disadvantages. The cost of special rollers or brushes is higher than a standard roller or brush. The cost of the special fluid tubing is required to both allow the flow of fluid and provide a structure that is able to withstand the rigors of a hand application device. This special arrangement is complicated, more difficult to use, and more costly. The fluid on the inside surface of the roller can cause the roller or brush sleeve to be bonded to the frame. This is especially true if the fluid is an adhesive or two part component substance. Rollers can quickly become ruined as the two part component material cures. The tube delivering the fluid to the inside of the applicator is necessarily in contact with the applicator itself This arrangement provides an additional opportunity for clogging as the surfaces of the applicator and the surfaces of the delivery tube become coated with curing liquid.
In one embodiment, the mixing portion 126 is removably attachable to a carrier 200 and is in fluid communication with the fluid dispensing portion 124. In one embodiment, the mixing portion 126 receives a first part of the fluid F via a first port 150 and a second part of the fluid F via a second port 152 and mixes the first part and the second part theretogether to create a mixed fluid. As the mixing portion 126 is in fluid communication with the fluid dispensing portion 124, the plurality of apertures 140 can then be used to apply the fluid F having the first part and the second part mixed theretogether to the fluid applicator 122. In one embodiment, the mixing portion 126 may be a Vee Manifold available from Rooftop Equipment Inc. and described in U.S. patent application Ser. No. 13/804,748, U.S. Pat. No. 9,242,846, entitled “Vee Manifold”, the entirety of which is hereby incorporated by reference herein.
In one embodiment, referring to
As described above, referring to
For example, in an exemplary embodiment, a fluid applicator 122 may be 12 inches in length and a material or fluid F may be applied from the nap of the fluid applicator 122 to a flat substrate, and the fluid applicator 122. is flat and matches the flat substrate. A cross-sectional view of the substrate reveals 12 inches across the horizontal substrate measurement and 12 inches across the fluid applicator 122. Streams of fluid F being applied to a nap of such a flat fluid applicator 122 are spaced equally to provide a consistent application of fluid F from the fluid applicator 122 to the substrate. For instance, a 12 inch fluid dispensing portion 124 with 12 ports or apertures 140 is secured parallel to the axle of the fluid applicator 122 and about 2 inches away from the nap of the fluid applicator 122. Referring to
Equal spacing of the ports or apertures that provide a coating or fluid F to a roller do not provide sufficient coating for rollers and substrates having contoured surfaces. For example, in an exemplary embodiment, when a roller and/or surface to be coated is contoured, such as a metal roof, the cross-sectional view reveals 12 inches across the horizontal, but the linear measurement of the substrate is 16 inches. The greater distance is due to the contoured portion. If the same 12 streams of equally spaced coating, as described above with respect to a flat applicator, are applied to a contoured roller, then there is not enough coating or fluid being applied to the roller or applicator and consequently to the contoured surfaces of the substrate to provide the desired mill thickness of fluid to the substrate. The 1 inch on center ports providing 1 inch on center streams will contact the angled surface at approximately 1 ⅓ inches thereby leaving a film thickness that is insufficient. The result is that a substrate can be seen through the inadequately thin layer of coating or fluid applied. A white coating being applied over gray metal will appear gray on the ribs due to the inadequately thin layer of fluid applied.
A fluid application system 320 of the present disclosure solves these problems associated with providing coatings or fluids to rollers or applicators and to substrates having contoured surfaces as described in more detail below.
In one embodiment, the fluid applicator 322 for applying the fluid F to the substrate 100 is removably attachable to the carrier 200 and includes a body 330 having a first portion 24 and a second portion 26, as described in further detail above and with reference to
The fluid dispensing portion 324 provides a mechanism for applying and supplying the fluid F to a fluid applicator 322 having contoured surfaces. In one embodiment, the fluid dispensing portion 324 is removably attachable to the carrier 200 and includes a first section 340 including a plurality of first section apertures 342 and a second section 344 including a plurality of second section apertures 346. Referring to

Referring to
For example, the spacing of the ports or apertures 342, 346 of the fluid dispensing portion 324 of the present disclosure ensures streams of fluid F that contact a contoured fluid applicator 322 at a spacing that sufficiently accommodates all of the contours of the fluid applicator 322 and the contoured surface. This spacing of the ports or apertures 342, 346 of the fluid dispensing portion 324 of the present disclosure ensures that the proper streams of fluid F are supplied and at the proper distances for proper fluid coverage for every surface of the applicator and the substrate, e.g., at each of the flat and the contoured surfaces. In an exemplary embodiment, for example, a contour having a cross sectional view with 16 linear inches of nap to accommodate the 16 inches of surface in 12 inches of horizontal distance will have about 14 streams of coating. The ports and streams on the flat surface will have equal spacing, for example, 1 inch on center, while the ports and streams associated with the contoured surface with be about ⅔ of an inch on center.
In another exemplary embodiment, for example, if a roller is 11 inches in length when applying material from the roller nap to a flat substrate, the surface of the roller is parallel to the substrate. A cross-sectional view of the surface reveals 11 inches across the horizontal substrate measurement and 11 inches across the roller. But when a surface is contoured, such as a metal roof, the cross-sectional view reveals 11 inches across the horizontal but a linear measurement of the substrate is 16 inches with more distance being at the contoured or angled portions. A fluid applicator that has been adapted to this contour will also have a cross sectional view with 16 inches. If streams of coating or fluid are provided by a straight row of ports having equal spacing the fluid applicator will not have sufficient coating cm the contoured or angled portions. Ports must be moved closer together to accommodate the 16 inches of the substrate over the horizontal 11 inches, for example.

In other exemplary embodiments, other diameters of the apertures 342, 346 can be used to accommodate other fluid applicators 322 and substrates 100 having any variety of different contoured surfaces using the techniques described in the present disclosure. In this manner, a fluid dispensing portion 324 of the present disclosure advantageously applies and supplies an appropriate, sufficient, and consistent amount of a fluid F to all portions of a fluid applicator including all of the different contoured surfaces of the fluid applicator. By properly supplying a fluid F to a fluid applicator in this manner ensures that the fluid applicator then properly coats a substrate with the desired fluid.
As shown in
In other embodiments, by varying the diameters of the apertures 342, 346, the first section apertures 342 are spaced a first distance apart and the second section apertures 346 are spaced a second distance apart, wherein the first distance is less than the second distance. In other embodiments, by varying the diameters of the apertures 342, 346, the first section apertures 342 are spaced a first distance apart and the second section apertures 346 are spaced a second distance apart, wherein the second distance is less than the first distance.

The fluid application system of the present disclosure offers many advantageous benefits over conventional systems. For example, two component coatings or other fluids are commonly poured into a five gallon pail then mixed with a paddle mixer attached to a drill. These mixed fluids are then poured out of the pail onto the substrate. Once on the substrate the fluid is in large undesirable puddles which must be pushed and pulled with a squeegee, roller, or other applicator. Since the fluid is curing chemically the viscosity is getting greater as each moment passes. The effort to push or pull the fluid into an even film thickness becomes increasingly difficult with passing of each curing moment. Since many of these fluids have a pot life of only a few minutes improper spreading is hard to avoid. Prior art methods of applying these two-component fluids can also be accomplished using a single bead or ribbon of fluid being applied directly to the substrate flowing from a static mixing tip. While these beads do eliminate the need for mechanical stirring in a pail with a drill, the beads or ribbons that flow out of the static mixing tip and onto the substrate surface must still be pushed or pulled to form a continuous monolithic film of fluid. The problem with this method is that it leaves marks on the substrate in the shape of the bead. This happens because these fluids are becoming more viscous as the mixed fluid cures. The condition of the mixed fluid at the time it contacts the surface is different than the condition of the mixed and curing fluid at the time when an attempt is made to move the fluid with a squeegee or roller. Therefore, when the two-component fluid cures the pattern of the beads is transmitted through the fluid and the pattern of application can be seen. With the present invention the stream of the fluid flows onto a fluid applicator prior to contacting the surface. This eliminates the bead lines. The spreading of the mixed two component fluid by a fluid applicator as it flows from the mixing tip onto the fluid applicator and then onto the substrate provides an even monolithic distribution of fluid. It also decreases the length of time required from when the two fluids begin to chemically react and cure to the time where the mixed fluid has reached its' final position on the substrate. This time is very critical and especially when additional materials are to be broadcast into the wet fluid. Sand, walnut shells, or colored flakes are commonly called for in these applications. If the fluid cures prior to broadcasting the grains or flakes they will not embed into the fluid. These are meant to be a permanent part of the application but will be swept away if the fluid is cured prior to contact. The total pot life of many materials is 15 to 20 minutes. When the two components are mixed in a five gallon pail, then poured out onto the substrate, then pulled and pushed to spread out evenly, there is little time left to broadcast the final components into a wet fluid. Consequentially, the batches of mixing must remain small enough for all the steps to be accomplished prior to curing. This process is very time consuming. The present invention expedites the application time which leaves ample time to embed the finishing materials. This process is not only faster for each batch, but it also allows the application process to be continuously flowing rather than stopping and starting with each batch. This continuous flow greatly enhances the efficiency of the overall application process.

The fluid application system of the present disclosure offers many advantageous benefits over conventional systems. For example, the application of multiple component fluids is most commonly performed in a manner as described above where the materials are mixed in a pail and then applied by hand. Some multicomponent fluids are applied with a spray, but this requires personnel to be skilled in the art of two-component application precautions as well as being skilled in the operation of the special two component equipment pumps. When this skilled approach is in a controlled environment and the application is on a flat surface the process can be successful. However, when the project entails the added hazards of being elevated to a roof, attempting to coat a contoured surface while being wary of erratic winds, the task of spraying a two-component fluid is precarious. Wind driven two component fluids that have been atomized can damage buildings and cars as well as being extremely dangerous to humans. With all this uncertainty there remains a need to use a contoured fluid applicator which supplies streams of mixed fluid directly to a fluid applicator for application to a surface. The distances between the streams of mixed fluids are increased or decreased to correspond to the various contours of the fluid applicator which are adapted to the contours of the surfaces. In the present disclosure, by adapting the distances between static mixing tips, the corresponding streams exiting the mixing tips are aligned as required to meet the proper mill thickness coverage rates of a contoured surface. The present invention overcomes the challenges of prior art application methods.

The fluid application system of the present disclosure offers many advantageous benefits over conventional systems. For example, two component fluids flow into a static mixing chamber and then exit out of the chamber as a new mixed fluid. Subsequent to the mixing process the mixed fluid flows out of the mixing chamber and is then distributed through multiple apertures. This downstream distribution of the mixed fluid is accomplished by utilizing multiple apertures. The distance between the apertures is made to correspond to the contour of the fluid applicator which is adapted to the contours of the substrate. Accordingly, when the greatest rise in the contour of the applicator is located near the center of the applicator then the corresponding streams of fluid are also at this central area. As fluid flows onto the contours of the fluid applicator the streams form a rolling puddle in front of the applicator as it moves along the substrate. This rolling puddle contains enough fluid to adequately coat the entire width of the fluid applicator. This allows the puddle to feather out near the edges of the roller. Because the streams are located so as to contact the angles of the contoured applicator the corresponding angles of the surfaces are sufficiently coated with the dual component material. Prior art methods of spraying or rolling have required the operator to rotate the application device so that each individual contour can be coated one at a time. Advantageously, the systems of the present invention allow all contours to be reached simultaneously.
