Decoma GmbH in Sulzbach, Germany, picked two Kuka KR 150 KS robots, mounted on top of large-tonnage injection molding machines, for two new bumper fascia production lines manufacturing parts for the DaimlerChrysler PT Cruiser and the Audi A4.
Decoma previously had used linear units to handle bumpers, but they took up too much floor space.
“We needed a solution that would cover handling the car bumpers and sill covers after the injection molding process was complete, as well as removing the film gates from the sill covers,” said Dietmar Hurth, industrial engineer for Decoma.
Working from above, one robot takes the bumper from the press and places it with its side pieces down onto a form-fitted fixture. The robot then removes the film gates, using a blade attached to its gripper. The gates drop into a refuse bin. Next, the robot transfers the bumper to a conveyor belt, which takes the part out of the safeguarded zone.
On the sill covers, the robot takes a pair of covers out of the press and sets them on a table, while the robot holds the parts in position.
The table, which is equipped with 14 blades, cuts all the gates at the same time. Meanwhile, the Kuka robot also holds the gates using pincers. The robot then moves the sill covers to the same conveyor and drops the gates into a container.
The shelf-mounted robot is lightweight but strong, so it can be mounted on top of the press to save space.
Kuka Robotics Corp. is based in Clinton Township, Mich., near Mount Clemens.
