Patent number: 6849130Abstract: An apparatus for operating a fluid dispensing gun to dispense a fluid onto a substrate moving relative to the dispensing gun. The apparatus has a sensor that produces a sensor feedback signal in response to the fluid dispensing gun changing operating states. A control is connected to the sensor and provides first signals causing the fluid dispensing gun to change operating states. The control has a detector producing a compensation signal representing a difference between the occurrences of one of said first signals and the sensor feedback signal. The control then adjusts a subsequent first signal in response to the compensation signal. Thus, the control automatically compensates the operation of the fluid dispensing gun in real time for changes in the switching time of the fluid dispensing gun required to change its operating states.Type: GrantFiled: October 31, 2001Date of Patent: February 1, 2005Assignee: Nordson CorporationInventor: Peter W.
