Black River Falls, Wis. – Michael Dougherty, President of D&S Manufacturing, announces that to meet the goal of a sizable increase in their robotic welding envelop, the company has integrated a new cell system featuring 2 ABB IRB 2600 Six Axis Robots, 2 Lincoln Welding Power Supplies and an IRBP K Servo Positioner, all controlled by a single ABB IRC5 MultiMove Control.
D&S’s team approach to selecting new equipment mobilized 11 dedicated employees, including robot operators, welders, engineers and programmers, who formed sub teams to evaluate equipment options, layouts, fixturing and logistics. These specialists concluded that Wolf Robotics, LLC presented the best option to fulfill their objective of an increased welding envelope, increased deposition rates, and an increase in throughput.
According to Joe Lane, Continuous Improvement Manager, “this new system will take robotics at D&S to another level. With the integration of the new, more agile, faster robots and the twin station positioner, we will greatly increase the size of weldments that we can produce robotically and expect to attain dramatic improvements in cycle times with multiple robots welding in coordination on the same part.” Lane explained that efficiency will be gained since the operator is able to continue to work on the load side of the positioner, while the robots are welding on the other side; there is no waiting to load and unload. To further enhance efficiency, D&S will utilize load-and-go fixturing to eliminate the need to perform manual tack welding prior to loading components into the carousel.
The carousel positioner has a 2200 pound capacity and offers a swing diameter of 55” with 157” between head and tailstock; the largest K style positioner offered by ABB. The integration of 2 robots doubles the deposition rate and increases reach opportunities. The robotic side also features a quick neck changing station which will rapidly change welding torches, increasing robotic dexterity and welding reach and providing for the completion of complicated welding requirements in a single cycle. To reduce robot downtime, a Torch Cleaner Service Center has also been integrated into the welding system.
The fully coordinated operation of all the equipment in this turnkey cell is made possible through integration at Wolf Robotics. The user friendly Operator Interface, proprietary to Wolf Robotics, provides easy access to all necessary information and control functions used to operate the robotic welding cell through a touch screen display. Two important software options D&S utilizes are touch sensing, to allow the robot to find the exact position to begin the weld, and seam tracking, so the robot can utilize feedback to follow any variations in a weld joint. These exciting features contribute to excellent repeatability, improved quality, higher process speeds and shorter lead times.
