The decision to use robotics for dispensing adhesives arose from the number of welders and manhours required to weld the overflow on the lavatories. In the search to streamline the process, the company chose St¿li's (Duncan, SC) RX90. This system is now working the day shift, 6 days a week, with a cycle time of 7.72 seconds.

Using adhesive on the overflow increases the life of the lavatories by producing a uniform seal. This automated dispensing process greatly increases production while keeping down the cost. The robot cell is located in the enamel area and is operator-free.

In the robotic cell, the lavatories move on a conveyor belt. The RX90 picks up the overflow part, places it under the dispensing nozzle and moves the overflow so that the entire rim receives a uniform coating of adhesive. The RX90 then places the overflow onto the back of the lavatory.

V-Trajsig software, designed by St¿li, and AIM Motionware, designed by Adept, are used to improve trajectory and arm movement while offering the operator an easier graphical user interface. The fluid movements obtained by V-Trajsig promote the uniform dispensing of the adhesive.
