An automated transport system is used in a laboratory environment to transport drawers to various positions in a cabinet incubator as well as to a position for manual loading and unloading. There is also an option for a visual assessment (qualitative assessment of the objects). A local PLC provides the transport functionality. The system should also be separated from the rest of the lab by a safety barrier.
The base frame of the system, which includes levelling feet and floor fastening, was constructed of Series 40 Aluminium Profiles to accommodate the axles. The lift unit (Z-axis) and the removal unit (Y-axis) were made from a linear unit with recirculating ball bearing guide and timing belt drive. The transverse module (X-axis) consists of a linear unit with roller guide. In addition to 36 drawer positions, the area of activity of the removal device includes a further park position along the outside edge at an ergonomic height. The system controller was installed with a UPS system for an uninterruptible power supply. Guarding with suspended sliding grates, a protective guard and emergency stop switch has also been installed.
