Abstract
Apparatus for electrostatic spray painting having a painting chamber to which is connected a spray gun fed by a paint powder delivery system. A powder supply provides a high potential across the painting chamber and the spray gun to develop an electrostatic field to pull the paint powder ejected by the spray gun toward a workpiece positioned within the paint chamber. A humidity sensor is located in proximity with the paint powder delivery system for detection of an amount of moisture. A humidity signal is produced in response to the sensed humidity. A remote computer may be connected to receive a plurality of process condition signals including the humidity signal and to provide a display indicative thereof.
Claims6
Apparatus for electrostatic spray painting, comprising:
- a painting chamber for receiving a workpiece to be spray painted;
- a paint powder delivery system for storing and supplying paint powder;
- a spray gun coupled to said paint powder delivery system, said spray gun being adapted to receive the paint powder from said paint powder delivery system and eject the paint powder into said painting chamber;
- a high voltage electrostatic supply coupled to said spray gun for applying an electrical force to the paint powder to transport the paint powder toward the workpiece;
- process condition responsive means for sensing a process condition characteristic and producing a process condition responsive signal;
- a processor for executing a personal computer operating system and for receiving the process condition responsive signal from said process condition responsive means and generating a second process condition responsive signal;
- a memory coupled to said processor for storing the personal computer operating system;
- means connected to said processor for receiving said second process condition responsive signal and for providing an output indication responsive to the second process condition responsive signal;
- and
- communication means connected to said processor for remote transmission of a digital signal indicative of said second process condition responsive condition responsive signal.
