Abstract
PURPOSE: To control paint film thickness with good stability by correcting the rate of dilution used for conversion successively at correct timings at the time of controlling the film thickness in accordance with the estimated dry film thickness converted from the detected wet film thickness with the rate of dilution.
CONSTITUTION: The wet film thickness detected with a film thickness detector 22 is converted with a rate of dilution in a converter 24, by which estimated dry film thickness is determined. This estimated dry film thickness and set film thickness are compared in a comparing operator 33, by which the rotating speeds and gaps of rolls 6W8 in a painting section 3 are regulated and the film thickness in controlled. At this time, the film thicknesses detected with the detectors 22, 23 are compared, and a correction value for the rate of dilution is determined. This signal is fed back with the delay by the time required for a steel plate 1 for moving from the section 3 to the detector 23. In this way, the hunting of the control system is prevented and the paint film thickness is controlled with good stability.
