Transfer Line Control
Precision control of a transfer line that handles the edging and tempering processes for sheet glass manufacturing.
Industries Served:
Automotive, Discrete Manufacturing, Glass Manufacturing
Products Used
- Mid-range PLCs
- PLC-based APM Modules
- AC Drives
- Man-Machine Interface software running on an Industrial PC
The Advantages:
- Increases production throughput tonnage by optimizing gapping of the glass.
- Reduces scrap through precision control, resulting in fewer crashes.
- AC drives help to increase uptime, reduce maintenance costs (when compared to long lead-time DC motors and drives) and improve system diagnostics.
- Rapid PLC throughput.
How It Works:
- AC inverters are combined with PLC modules in follower mode.
- These modules receive their master encoder speed reference from the furnace, and speed is precisely controlled on all axes to achieve proper gapping for the glass on the line.
- To support changing types of products on the line, recipes are downloaded to the control system, allowing for quick product type changeover and complete system diagnostics from one source.
- AC drivers communicate with the PLC, providing complete diagnostics and reducing system downtime.
