Positioner
1.2 System Overview
The Positioner can be used with a variety of applications that require
precise parts movement. Typically, the Positioner is integrated with one or
more Manipulators and Controllers in a work cell arrangement.
The Positioner is a two station headstock/tailstock (HS/TS) Positioner.
Because of certain operational dynamics, this type of Positioner is often
referred to as a “Ferris wheel” Positioner.
The main (sweep) axis and both tooling plate (orbital) axes are rotated by
individual Sigma-5 servomotors (working through gear reduction units)
that are controlled by circuitry in the Controller.
All three axes can be driven simultaneously during a sweep motion. In
addition, movement of the Positioner can be coordinated with Manipulator
motion to allow complex jobs such as the welding of circumferential joints.

The Headstock Drive Assembly, Headstock Swing Arm, and the Arc
Shield Assembly rotate around a main (sweep) axis and are limited in
rotation by hardstops located on the tooling drive swing arm.
