FLUID APPLICATION SYSTEM AND FLUID APPLICATION METHOD

摘要

A fluid application system includes: an application apparatus that discharges a fluid to a workpiece; a movement apparatus that moves the application apparatus and the workpiece; and a control apparatus. At the time of adjusting the output of a power source to thereby vary the discharge amount of the fluid from the nozzle by a target variation amount F1, the control apparatus sets the output of the power source to a value beyond a theoretical output N1 of the power source obtained from the target variation amount F1 of the discharge amount, and then sets the output of the power source to the theoretical output N1 such that the change amount of the internal pressure of the nozzle is coincident with an amount P1 by which the internal pressure of the nozzle needs to change, the amount P1 being obtained from the target variation amount F1 of the discharge amount.

1. A fluid application system comprising:
an application apparatus that discharges a fluid to a workpiece; a movement apparatus that relatively moves the application apparatus and the workpiece; and a control apparatus that controls the application apparatus, wherein the application apparatus includes: a power source; a fluid supply apparatus that changes a supply amount of the fluid per unit time in accordance with an output of the power source; and a nozzle that discharges the fluid supplied from the fluid supply apparatus, to the workpiece, and at a time of adjusting the output of the power source in a course from application start up to application end to thereby vary a discharge amount of the fluid per unit time from the nozzle by a target variation amount, the control apparatus sets the output of the power source to a value beyond a theoretical output of the power source obtained from the target variation amount of the discharge amount, and then sets the output of the power source to the theoretical output such that a change amount of an internal pressure of the nozzle is coincident with an amount by which the internal pressure of the nozzle needs to change, the amount being obtained from the target variation amount of the discharge amount.
