Johann Gg. Schopper GmbH & Co. KG in Zirndorf near the German city of Nuremberg has been manufacturing all manner of metal products and toys since 1928. The medium-sized family company is now in its third generation and its products include metal signs. To make these metal signs even more efficient to manufacture, Schopper GmbH turned to the robotics team at toolcraft. The result was a robot cell capable of automatically machining customised embossing plates that can be used to produce metal signs.
The brief was to construct a robot cell that could produce plates of various shapes and sizes. The completed cell uses a Stäubli TX90 robot and has two vacuum tables for the machining of positive and negative feedstock. The machining time had to be kept under 45 minutes.
In addition to providing the necessary hardware, toolcraft worked with software company unicam to supply the compatible software. Mastercam was used to program the paths. Meanwhile, the offline programming software Octopuz translated the program for the robot, providing everything needed for the automated processing of the embossing plates. The quality meets the high standards of manual production processes.
The project took a total of 20 weeks to complete. During this time, toolcraft provided everything from A to Z – from the hardware to the offline programming. In doing so, toolcraft has equipped the traditional process of manufacturing metal signs for the future.
