AMS Helps Piramal Glass Upgrade a Stepper Motor Pusher System
New controls improve reliability and save equipment and money

June 16, 2010, Vancouver, WA ─ Applied Motion Systems, a leading provider of drive and control systems to the glass container manufacturing industry, upgraded a stepper motor pusher system for Piramal Glass.

Piramal Glass manufactures specialty containers in large glass production plants around the world. At their Park Hills, Missouri plant, they had an outdated stepper motor pusher system prone to breaking down. Maintenance managers complained about the system’s unreliability and the difficulty of finding spare parts. In addition, it was hard to diagnose the cause of a problem when the system failed, and the system wasted energy and generated excess heat in current-limiting resistors.

Upgrading Saves Equipment and MoneyImage
Piramal wanted to upgrade the system without having to scrap the existing—and working—stepper motors. In addition, they needed to minimize any downtime that a system upgrade might require.

Ken Goheen and Bruno Zbinden, AMS systems engineers for the project, designed a drive and control system that replaced the old system with new, state-of-the-art features, while retaining the existing stepper motors. The new system featured:

  • Kollmorgen stepper drives with modern PWM technology
  • A Delta Tau motion controller capable of generating smoother motion profiles than the old controller
  • An easy-to-use and graphically rich operator interface with simple job setup and diagnostic messaging features
  • Readily available off-the-shelf spare parts
  • A “hot” spare drive ready to run any section by moving just one cable

Production and Reliability Results
This cost-effective upgrade solution resulted in Piramal significantly improving the pusher system’s reliability and performance without having to purchase a whole new system. Operators are thrilled with the new pusher system and enjoy its improved performance and reliability. Troubleshooting is easier now due to diagnostic messages displayed directly on the operator interface and alarm logs that users can view in a Web browser. A permissions-based security system prevents changes to operating parameters by non-authorized personnel.
