Patent Application

The subject matter of the present disclosure generally relates to structural coating application procedures. More specifically, it relates to a system and method for enhancing the spray-on, structural coating application process by integrating weather sensors with IOT technology directly into a plural component dispenser.
The first weather tools can be traced back to the 1400s when a Korean prince developed the first standard rain gauge. The first thermometer was invented in 1593 and the barometer was developed in the late 1600s. Over time, these weather tools were improved and refined and were sold together with wind speed and direction meters creating the first weather stations. In the early 1800's and 1900's, weather stations typically consisted of a few specialized analog tools. Humidity gauges measured the moisture content in the air, while rain gauges and barometers helped determine previous and future rainfall. This information could then be tracked in order to identify trends. Today, there are digital weather stations and many Wi-Fi weather stations with wireless internet connectivity that can better consolidate and report information so it is easy to view and understand. Some weather stations can even connect to smartphone apps or online services so people can access their weather information from anywhere. While many in the coatings application industry provide technicians rely on separate instruments to monitor local weather conditions, no patents were found that incorporated weather stations, IOT, Al and a software application with plural component dispensers.
The device herein disclosed and described provides a solution to the shortcomings in the prior art through the disclosure of a plural component dispenser with onboard, ‘smart’ weather station. An object of the disclosed subject matter is to improve the safety and effectiveness of the coatings application process. For example, a coating crew is spraying a two-part insulation on the exterior of a roof on a coastal airport. Over the course of the day, weather on the coast changes quickly and humidity levels increase beyond the curing threshold recommended by the coating's manufacturer. The weather station on the dispenser detects this change, generates a system alarm that stops the proportioning pump, and instantly alerts crew members and the manager that they need to stop spraying immediately via their smart phones to avoid a coating failure.
The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate some, but not the only or exclusive, examples of embodiments and/or features.
Other aspects of the present disclosure shall be more readily understood when considered in conjunction with the accompanying drawings, and the following detailed description, neither of which should be considered limiting.
In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms refer to the device as it is oriented and appears in the drawings and are used for convenience only; they are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation. Conventional components of the disclosed system are elements that are well-known in the prior art and will not be discussed in detail for this disclosure.
Other embodiments of the pump apparatus 20 can include double and single chemical coating dispensers (22) and can include other dispensing means, such as but not limited to hydraulic pumps etc. The control unit 40 of the spray rig 10 can have an onboard microcontroller (including but not limited to arduino etc.) with buffer memory and can use Zigbee wireless protocol communication technology that collects data from the integrated environmental monitoring apparatus 30 and transmits it to a multitude of receivers (such as LAN, WAN, WiFi, cellular networks etc.).
The integrated environmental monitoring apparatus 30 of the spray rig 10 is disposed in proximity to the work location where the spray coating is to be applied so that local conditions can be monitored by the sensors 32 of the station 30 as the application process is performed. Accordingly, the environmental monitoring sensors 32 are remotely mounted in proximity to the applicator 70 and communicates wirelessly or with a wired communication to the pumping apparatus 20.
In general, the integrated environmental monitoring apparatus 30 can monitor conditions suited to the type of spray coating being applied. Many chemical compositions have particular temperatures and humidity conditions under which the spray coating needs to be applied. If the environmental temperature is too high or too low or if the humidity level is too high, the spray coating may not properly cure and may not perform according to its intended use. Other conditions can be monitored.
In this way, the system 10 can enhance the safety of structural spray coating applications. For example, it has been well-documented that when roofing companies fail to understand weather conditions when applying coatings, these coatings can fail to cure causing an unstable, ‘runaway’ reaction and off-gassing of toxic solvent vapors for months—rendering a structure uninhabitable.
For example, the environmental monitoring sensors 32 can include independent sensors configured to measure a plurality of the conditions selected from the group consisting of wind speed, wind direction, ambient temperature, humidity, barometric pressure, and the like. Moreover, a surface to be coated with the spray coating may need to have a particular dryness and temperature for the spray coating to be applied properly. To that end, the integrated environmental monitoring apparatus 30 may include or may interface with a sensor 34 for monitoring substrate moisture content and/or substrate temperature. These and other sensors 32 can be used to monitor various conditions.
The integrated environmental monitoring apparatus 30 can communicate through wireless or wired communications with the pumping apparatus 20, where the control unit 40 and processing may be located to monitor the sensed conditions and initiate alerts and the like. Should the sensed conditions fall outside of specific specifications for the spray coating and its proper application, the system 10 can initiate alerts, stop application, stop pumping, and perform other operations. For example, the applicator 70 (e.g., spray gun) operated by the worker may have a user interface 72 that provides an alert (audio and/or visual) or details of the alerted condition. The applicator 70 may have an electronic control 74 that disengages or deactivates the ability of the application to dispense the spray coating. The control unit 40 of the pumping apparatus 40 may have a user interface that provides an alert (audio and/or visual) or details of the alerted condition. The pumping apparatus's control unit 40 may have an electronic control that shuts off the delivery of the spray coating or the like.
The alert can also be sent to a cloud network (23:
If the conditions are within specifications (Yes at Decision 120), the pumping apparatus 20 and the applicator 70 can begin the coating process (Block 124). During application, the system 10 continues to monitor the current conditions measured by the monitoring sensors 32 to determine whether any one or more of the conditions have changed outside of the specifications (Decision 130). If conditions have not changed outside of specifications (No at Decision 130), then the system 10 continues performing the coating process (Block 124) and continues to the end of the job (Block 142) as long as the conditions remain within specifications. At the end of the job, the system 10 records a job report. When remote communications are available, the system 10 can upload the job report for later review and analysis (Block 142). Accordingly, the control unit 40 can monitor the integrated environmental monitoring sensors 32 for each individual job. The control unit 40 has a communication interface 45 that connects with a communication interface 34 of the apparatus 40 to obtain sensed conditions. In turn, the control unit 410 can record the job record on a storage media for storage and analysis and can then upload the individual job record via a wireless link for storage and analysis.
If conditions have changed outside of specifications (Yes at Decision 130), then the system 10 alerts the applicator's device 72, 74, the worker's device 80, and/or the pumping apparatus 20 to stop the application until conditions return back to specifications. Therefore, operations can revert back to monitoring conditions until the coating process can be performed (Decision 120).
