    摘要： A system for accurately dispensing controlled amounts of viscous material. The system includes a pressurized supply of the viscous material, a dispenser connected with the pressurized supply and a feedback control for ensuring that a discrete dispensed amount corresponds closely to the desired dispensed amount for a particular application. The different methods of feedback control include changing pressure of the pressurized supply after measuring a dispensed amount and comparing the dispensed amount with a stored value representing the desired amount. Another manner of feedback control includes changing an air operating pressure associated with the dispenser. A third type of feedback control includes adjusting the duration that the dispenser is maintained on to dispense the viscous material. Each of these types of feedback control are preferably used in succession, as necessary, to ensure that the desired amount of viscous material is discharged from the dispenser. Methods of controlling an amount of viscous material discharged from a dispenser further include using one or more of the feedback controls described above.

    摘要： A control system for use in a liquid dispensing system to measure and adjust a liquid spray pattern dispensed from the liquid dispensing system. The control system includes a sensor that detect edges of the liquid spray pattern and, from the detected positions of those edges, is operable to adjust the liquid spray pattern to a pattern width set by the operator. The control system is also operable to measure the width of the liquid spray pattern and the offset of the liquid spray pattern relative to a nozzle centerline of the liquid dispensing system and provide warnings to the operator if those measurements fall outside of acceptable ranges.
