42 UR machine tending robots improve price-competitive production
Once Trelleborg Sealing Solutions finally came across Universal Robots it was a match made in heaven. The space problem around the CNC machines was overcome as the robotic arms require no safety shielding – and productivity went up as one operator can now attend to eight machines at a time instead of just three.
12-18 months per robot
Following a major modernisation of the machinery at its Danish production site Trelleborg Sealing Solutions was faced with a serious space problem: The new CNC machines were taking up far more cubic metres than the old-fashioned turning machines. As a consequence, optimising processes by means of robotic arms was made difficult.
“We researched the market for suitable robots for years, but every single one we looked at required safety shielding. It made them unattractive for us, since we are unable to extend the actual production area at our factory in Denmark,’ says Production Manager at Trelleborg Sealing Solutions in Denmark, Jesper Riis.
To be perfectly suited for Trelleborg’s requirements the robot also needed to be easily deployed and programmed to accommodate a production with orders ranging from a single unit to series of several million.
Trelleborg Sealing Solutions finally came upon the robot arms from Universal Robots. A thorough risk assessment revealed that they were in most cases allowed to run without safety shield, which solved the restricted space challenge. Today, 42 UR robots carry out machine tending on mainly CNC machines, enabling exactly the agile manufacturing demanded by Trelleborg as the robots are easily adjusted to new sizes.
Another tangible benefit of the UR robots is the fact that they allow one operator to keep a cell with eight CNC machines running at a time whereas before the maximum was three. As a result, Trelleborg has saved 1.5 employee per cell per shift – and is able to offer even more price-competitive products than before.
