  • Apparatus and method for detecting liquid flow from a spray device
    Patent number: 7182271
    Abstract: A flow sensor for detecting liquid flow generated by a spray device is non-invasive and capable of responding to rapid changes in the flow. The flow sensor includes a light emitter and a light detector, which may be disposed adjacent the liquid outlet of the spray device and oriented such that a light beam projected by the light emitter is aimed at the spray generated by the spray device and reflected by the spray into the light detector. The light detector senses the reflected light and generates an output indicative of the presence of the flow from the spray device. A deviation of the spray from the intended spray axis may also be detected.

  • Spraying system for progressive spraying of non-rectangular objects
    Publication number: 20060257581
    Abstract: A system and method for spray gun or nozzle control wherein the spray gun liquid discharge pattern is dynamically varied to correspond to the dimensions of a moving target object or a portion of the moving target. The spray gun includes inputs for fan air, atomizing air, and liquid, as well as cylinder air. Upon detection of a target object approaching, such as on a conveyor belt, the fan air pressure, atomizing air pressure, liquid pressure, and cylinder air pressure are varied according to predefined or contemporaneously generated curves to provide a spray pattern that corresponds to the shape of the target object or portion of the target object, thus minimizing waste and inefficiency due to overspray.

The spraying device has inlets for at least two fluids, such as water and air, and a mixing chamber in which the fluids are mixed. A mixture pressure sensor is mounted on the spraying device to detect the pressure of the mixture. The input pressures of the fluids entering the spraying device are also measured. The measured input pressures of the fluids are used to calculate a predicted mixture pressure based on an empirical formula, which has parameters that can be derived when the spraying device is installed in its operating position. The calculated pressure value and the measured actual mixture pressure are then used in a comparison process to determine whether or not the spraying device is functioning properly.

  • Internal mix air atomizing nozzle assembly
    Patent number: 7108203
    Abstract: An internal mix spray nozzle assembly adapted for operation with lesser pressurized air requirements. The spray nozzle assembly includes a liquid passage for directing a liquid flow stream against an impingement pin, and an air guide is provided for forming an annular pressurized air passage about the liquid flow stream for striking and atomizing a laterally spreading dispersion of liquid from the impingement surface. For enhancing liquid atomization, the air guide defines a relatively narrow width air flow opening for substantially accelerating and increasing the pressure of the atomizing air stream, and the impingement pin is formed with a relatively large primary impinging surface and a parallel downstream secondary impingement surface that facilitates further liquid particle breakdown and prevents the accumulation of liquids about the bottom of the impingement pin.
