Loading and unloading of machine tools

MAINZ - Hirata has developed a new robot cell for automated loading and unloading of machine tools. With this automation unit, productivity can be increased and employees in production can be relieved. The automation unit consists of six main components: Palletiser, two transport trolleys, 6-axis robot with dual gripper unit, cleaning station and optical measuring station. The control connection of the automation unit to the machine tool and a higher-level computer is also part of the scope of services.

The handling of the trays loaded with workpieces, the loading and unloading of the machine tool with the workpieces, the alignment of the workpieces and the cleaning and measuring of the finished parts after machining were automated. The 6-axis robot picks up the raw parts from the tray using the SKIP function and brings them to the alignment station. The robot then loads the machine tool with the raw parts or removes the finished parts from the machine tool, takes them to the cleaning station and then to the measuring station before placing them back on the corresponding trays.

The palletising system, designed for different types of foam trays, provides the raw parts in trays for machining. After machining, the trays with the finished parts are stacked again. Loading and unloading the palletiser with trays takes place without interrupting the actual automation process, thus avoiding unnecessary downtimes.

The optical measuring station integrated in the automation unit checks the finished parts 100 % after cleaning. The measurement data determined here are passed on to a higher-level computer, which determines the target/actual differences and sends them back to the automation unit. A finished part that is defined as good is placed back in a tray by the 6-axis robot in exchange for a blank part. The NiO parts are discharged on corresponding conveyor belts.

Hirata's new robotic cell offers the opportunity for entry into machining automation, improving productivity and competitiveness.
