"For the new generation of assembly lines, we were able to use the measuring and assembly stations from our proven high-end lines almost unchanged. On the one hand, this means that our customers can expect the same precision, stability and 7-second cycle times as achieved by the most powerful of the previous lines. On the other, it has enabled us to focus on all the new possibilities that SuperTrak offers us," adds Song.
Harrandt also retained the control system for the assembly processes, adding a B&R controller for the SuperTrak system. The control solution provides the high-speed data transmission Harrandt needs for seamless monitoring and traceability of the line's 12 (or optionally 16) shuttles. The shuttles can also be moved to any position via software with a repeatability of ±0.01 mm. As a result, pistons of different sizes can be aligned so that the casing line always comes to rest in the same place.
Harrandt has taken advantage of this positioning flexibility to develop a universal workpiece holder for cylindrical or cuboidal workpieces that can accommodate many different piston sizes. This alone has led to a significant reduction in the number of change parts and the time required for changeovers.
SuperTrak also enables higher transport speeds and slower processing steps can be distributed across multiple identical stations to maintain a faster overall cycle time. This is possible because shuttles can simply pass through unneeded stations without stopping.
