Electroimpact's E4000 LVER riveting machine entered service in 1998 assembling A320/A321 upper wing panels at the Airbus wing manufacturing facility in Broughton, Wales. Airbus's recent introduction of the Sharklet modification to the wings of the A320 family of aircraft necessitated a number of changes to the machine and fixture to accommodate the revised wing geometry. Electroimpact and Airbus also worked together to identify a wide range of machine improvements and updates. A short list of the changes made to the machine includes a new CNC, new motors, scales, spindles, and new technologies such as laser tracers and normality sensors. The end result is a faster, more accurate machine with state-of-the-art controls ready to support Airbus's A320/321 wing panel assembly for the next 15 years.

The newest generation of automated fastening machines require a feed system that is smaller, more flexible, and faster than any currently available. The feed system must be compact enough to fit on a robot base, yet have a capacity large enough to support unmanned production for hours. A large variety of fasteners must be supported and the entire system must be reloaded or reconfigured in minutes to match the next work piece being assembled by the machine. When requested by the part program, the correct fastener must be released directly and immediately into the feed tube to minimize cycle time. This paper describes a new “plate cartridge” feed system developed to meet these needs.

A fully automated off-line cartridge filling station has been commissioned to support the new Boeing SAL production cell. The filing station uses automated fastener feed technology that is typically found on the machines themselves. Incorporating this technology off-line in place of the traditional manual handling processes extends the benefits of automation beyond the main manufacturing cell. A single operator is able to keep up with the demand of eight production fastening machines while maintaining the highest levels of accuracy and quality. Additional benefits to this application of automation include reduction of the operators exposure to risks associated with manual handling and repetitive tasks.
