Abstract:
A system for operation of pneumatic tooling, comprising a plurality of pneumatically operable tools, a servo-controller which is switchable using a CPU to actuate any one of the plurality of tools to move it to a desired position, and a position transducer which includes an element which is displaced from a home position by such actuation of any one of the plurality of tools, said position transducer sending a position feedback signal to indicate to said servo-controller when the desired tool position has been reached, wherein said servo-controller produces a pneumatic output connected to plurality of valves, each valve in turn being connected to a corresponding one of the tools, said CPU switching said servo-controller so that only one valve is energized at any time, each valve when at rest routing air to hold its tool in the home position, and when energized routing the pneumatic output of the servo-controller to the tool.
