Eliminating manufacturing production bottlenecksAutomation plays a key role at the plant and blends together the art of glassmaking with the high technology needed to meet production, quality, consumer safety, and environmental protection goals. At the heart of the plant’s automated Shop Floor Information System (SFIS) is
iFIX from GE Vernova. This integrated information system collects and presents data from all steps in bottle making—batch, furnace, forehearth, mold shop, forming, lehr, inspection, and packing. The system serves multiple users at Gallo Glass—from operators on the lines to maintenance managers to senior managers who need quick, graphical reports via the Web.
The glass plant operates 24/7, utilizing 14 production lines. Each line starts with hot molten glass and ends with inspection, followed by packing. iFIX presents data collected from all devices on the lines, and the beginning and end of each line has an iFIX node. With an open architecture, the software connects to the plant’s installed base of equipment, such as sensing and inspection devices, programmable logic controllers (PLCs), scales and timing systems, communicating over Ethernet TCP/IP. The plant uses a client-server database architecture for fast communication and lower costs, and operates on a server-based computing model, the iClientTS terminal server version of iFIX running on a CITRIX server farm, and dedicated Windows terminal devices as clients.
Conceptualized by Gallo, designed and implemented by integrator Saber Engineering with a team that included Brian Thomas, Dennis Hopkins, and Bob Sullivan, the iFIX system includes over 20 Human Machine Interface (HMI) screens and generates 30 reports for the glass plant production team. This easy-to-use web-based monitoring and control software works in conjunction with an Oracle database to consolidate the data from the plant’s devices, then transform that real-time data into dynamic text, alarm, and graphic displays. Information is presented on the terminals located on the lines for a quick, easy-to-view snapshot of production. Operators and managers can view key performance indicators (KPIs) such as percent pack, which displays the number of bottles successfully produced for every 100 attempts, defects, losses, production quantities, and more. Essential to success, the system provides timely notification of defects so that operators can correct production and boost quality.
As an example, by analyzing the data from the plant floor processes, the team was able to redesign the glass molds to engineer out defects and decrease cracking. This change has reduced scrap and improved yield. Additionally, the team has perfected wall thickness and distribution—a long-term improvement that affects the amount of liquid that goes into the bottles—using wall thickness run charts.
