Abstract
System and methods for applying a liquid coating to a substrate are disclosed herein. One exemplary method includes a flow control routine in which the velocity of an applicator, or other parameter affecting the amount of material applied to the substrate, is iteratively adjusted. The amount of the adjustment performed in each iteration is tracked. When the sum of the adjustments by the flow control routine exceeds a predetermined threshold, a fan width control routine is initiated in which the fan width of the stream of material applied by the applicator is adjusted.
Claims85
A method of applying a material to a substrate, the method comprising:
- coating a first substrate with the material using an applicator;
- determining, in response to completion of the coating of the first substrate with the material, a first total amount of the material applied to the first substrate;
- comparing the first total amount of the material applied to the first substrate to a first predetermined control range;
- determining, in response to the comparison of the first total amount of the material applied to the first substrate to the first predetermined control range, that the first total amount of the material applied to the first substrate is outside of the first predetermined control range;
- adjusting, in response to the determination that the first total amount of the material applied to the first substrate is outside of the first predetermined control range, a velocity of the applicator, a pulse rate of the applicator, or a temperature of the material by a first adjustment amount to change a total amount of material applied to a subsequent, second substrate;
- coating the second substrate with the material using the applicator;
- determining, in response to completion of the coating of the second substrate with the material, a second total amount of the material applied to the second substrate;
- comparing the second total amount of the material applied to the second substrate to the first predetermined control range;
- determining, in response to the comparison of the second total amount of the material applied to the second substrate to the first predetermined control range, that the second total amount of the material applied to the second substrate is outside of the first predetermined control range;
- adjusting, in response to the determination that the second total amount of the material applied to the second substrate is outside of the first predetermined control range, the velocity of the applicator relative to a substrate, the pulse rate of the applicator, or the temperature of the material applied to a substrate by a second adjustment amount to change a total amount of material applied to a subsequent substrate;
- summing the first adjustment amount and the second adjustment amount to determine a total adjustment amount;
- comparing the total adjustment amount to a predetermined threshold;
- determining, in response to the comparison of the total adjustment amount to the predetermined threshold, that the total adjustment amount is greater than the predetermined threshold;
- and
- adjusting, in response to the determination that the total adjustment amount is greater than the predetermined threshold, a pressure of the material supplied to the applicator or a fan width of the applicator.
