FANUC America Authorized System Integrator Durabotics developed this automated system to dispense adhesive onto the seams of buckets and tubs. This extremely flexible and compact system can handle 11 different bucket sizes ranging from 2 quarts to 17 gallons, from 6 inches to 24 inches in diameter, and from 5 to 12 inches in height. Production rates range from 5 buckets per minute for larger bucket sizes to 12 buckets per minute for smaller buckets.
To do this, Durabotics’ system utilizes FANUC’s six-axis LR Mate 200iD/7L long arm robot, the all-around perfect choice for nearly any job that requires an ultra fast and flexible robotic solution. Buckets are placed on an adjustable infeed conveyor and fed to the FANUC LR Mate robot. Each bucket reaches a flat belt staging conveyor in the robot adhesive dispense area where the FANUC LR Mate applies adhesive to the bucket seams.
It successfully accomplishes the precise adhesive bead application through the use of an automatic bucket-centering device with vision system. The vision system uses a high-resolution 5-megapixel camera and special lighting to locate the bucket, find the seams, and provide the seam coordinates and center ring seal to the FANUC robot. Then a black light and Graco’s PCF Dispense Controls coordinate with the vision system to verify that the dispense was successful after adhesive is applied. Graco’s PCF Adhesive Dispense System consists of a pumping system, controller, nozzle and feedback. Once a bucket is complete, a pneumatically actuated device pushes the bucket to an outfeed conveyor out of the system.
This system’s highly advanced vision system, solves the difficult problem of finding and distinguishing seams in highly reflective objects, where it can be difficult to distinguish between seams and die marks made from the forming process.
This exceptionally flexible technology is not limited to buckets and tubs in its scope of product applications. Durabotics can develop automatic systems to caulk, seal, or apply adhesive to a variety of products of many different shapes and sizes, including windows and other objects and applications. Together with this advanced vision system, Graco’s PCF Adhesive Dispense System and intelligent robotics from FANUC, this system provides ultimate versatility for automated adhesive dispensing.
