The Lavelli A21 is an automated system for coupling lids with latches. It was designed to minimize an operator’s actions to that of just placing a lid, with latch, onto a container. The operation of packing the ready-stacked lids — currently the only action remaining for an operator to handle — has also been predesigned to be fully integrated into the existing system using IoT and industry 4.0 technology. The system has two stations where operators can load lids and latches. The machine automatically assembles both lid and latch, pairs them, and then uniformly stacks them.
