Machine History

• Functional Description: The robotic cell was originally designed to feed a cutlery packaging machine. The system picked stacked forks from dedicated crates and transferred them onto a packaging conveyor at a loading speed of 100 pieces per minute. While the two SCARA robots were operating correctly, the crate exchange system (empty vs. full crates) was not optimally designed. For this reason, the robotic cell was eventually decommissioned. A short video of the robot in operation is available.
