Abstract
Disclosed herein is a method of paint application. This method has the following advantageous effects. More specifically, when different paint is used, desired paint is alternately supplied to a first paint feeder and a second paint feeder from a paint feed source thereby to enable efficient painting of a workpiece by a spray gun. On the other hand, when the same paint is used, the paint is supplied only to the first paint feeder without using the second paint feeder, thereby making it possible to reduce wastefully-discharged paint and to efficiently carry out any cleaning work.
Claims6
A method of paint application, comprising the steps of:
- feeding a desired paint to a first paint feeder from a grounded paint feed source through a first feed line having an electrically-insulated portion formed in at least one portion thereof;
- cleaning and drying said electrically-insulated portion of said first feed line thereby to electrically insulate said paint feed source from said first paint feeder;
- thereafter feeding paints to a spray gun from said first paint feeder thereby to carry out a painting process with said paint;
- cleaning a second paint feeder without supplying paint to said second paint feeder while said painting process with said paints is being carried out;
- after said painting process with said paint has been completed, feeding desired paint to said second paint feeder from said paint feed source through a second feed line having an electrically-insulated portion formed in at least one portion thereof;
- cleaning and drying said electrically-insulated portion of said second feed line thereby to electrically insulate said paint feed source from said second paint feeder;
- and
- feeding said paint to said spray gun from said second paint feeder thereby to carry out a painting process with said paint.
A method of paint application, comprising the steps of:
- feeding a desired first paint to a first paint feeder from a grounded paint feed source through a first feed line having an electrically-insulated portion formed in at least one portion thereof;
- cleaning and drying said electrically-insulated portion of said first feed line thereby to electrically insulate said paint feed source from said first paint feeder;
- thereafter feeding said first paint to a spray gun from said first paint feeder thereby to carry out a painting process with said first paint;
- wherein in a subsequent painting process, paint different from said first paint is used, said method further comprising the steps of:
- cleaning a second paint feeder without supplying a second paint to said second paint feeder while said painting process with said first paint is being carried out;
- after said painting process with said first paint has been completed, feeding said second paint to said second paint feeder from said paint feed source through a second feed line having an electrically-insulated portion formed in at least one portion thereof;
- cleaning and drying said electrically-insulated portion of said second feed line thereby to electrically insulate said paint feed source from said second paint feeder;
- and
- feeding said second paint to said spray gun from said second paint feeder thereby to carry out a painting process with said second paint.
