CEE plug connection assembly: Linear transport system with matching handling components – supplied complete and ready for installation from WEISS.

Challenge

As a classic custom machine builder, the company Wilei from the Black Forest was looking to implement an assembly line for CEE plug connections. Alongside a short cycle time, the particular challenge here was handling the very large number of different versions. For reasons of space and with a view to potential expansion, a linear system had been specified from the outset for transportation of the units.

Solution

All components for transport and handling come from WEISS and were supplied as a complete, ready-for-installation system. The LS 280 linear system perfectly fulfils the stipulations in terms of cycle time and positioning accuracy for transporting the workpiece carriers. The gentle motion sequence is another plus point. The necessary handling is performed by a combination of freely programmable units, comprising two linear axes (HG25, HL 50), as well as one ST55 rotating unit. To save space, a total of three handling groups of this kind run on a single linear motor axis that measures one metre in length (HN 100). The perfectly matched overall composition ensures a high degree of flexibility and precision, as well as a low cycle time of 8.5 seconds.
