Proportional Edge Guiding

Most continuous web applications require some form of edge guiding.  Cost effective single-edge guiding can be achieved with the control system depicted in Figure M.1

Edge Guiding

This system must be used in conjunction with a rotary input linear actuator usually driven by a fractional horsepower motor and regen drive.  A proportional output photo-electric sensor and reflector provide an isolated output from 0 to 5 VDC based on percent of reflection.  There are several manufacturers of such sensors.

The photo-electric sensor is adjusted to give 2.5 VDC output when blocked 50% by the material edge.

This signal is processed by the EG1000-000 edge guiding control to drive a motor forward or reverse (left and right actuator operation) at a speed proportional to the position error – greater error gives higher correction speed.  This proportioning feature of the correction provides a very smooth and effective guiding action when compared to other “on-off” types of guiding often used.

This low cost regenerative control method bridges the gap between the lower performance non-proportional control systems and the higher performance servo driven systems costing much more.
