Filed:

Jun 30, 2000

Appl. No.:

09/608762

Inventors:

Akihiro Yanagita - Orion MI
Douglas L. Potts - Goodrich MI
Raymond J. Guzowski - Fenton MI

Assignee:

Fanuc Robotics North America, Inc. - Rochester Hills MI

International Classification:

G01F 1100

US Classification:

222 1, 222 61, 2221451, 222386, 222389

Abstract:

A method is disclosed for providing a steady transition state for an integral pneumatic dispensing system that is related to a robot. The method dispenses a single material using a pneumatic dispensing system having a single output including first and second shotmeters having first and second meters, first and second encoders and first and second pressure transducers. The method includes the step of loading the first shotmeter with the material. Once loaded, a pressure is applied to the material. The material is then dispensed out of the first shotmeter by forcing the material through the single output. Once the material in the first shotmeter is dispensed to a predetermined volume, the method begins to transition the flow of material from the first shotmeter to the second shotmeter. The transition includes the control of the volume being dispensed and the pressure applied to the material. By controlling both the volume and the pressure of the material, the transition between the two shotmeters is smooth allowing for uninterrupted production.
