Preventive maintenance is an indispensable part of Industry 4.0 and helps to avoid unplanned production downtimes. MT 174 comprises a separation process that serves as an application example for various maintenance tasks.
The material to be sorted is separated into three size fractions using a drum screen. The fine fraction is next sorted by colour. Maintenance work is carried out on the drive trains of the individual elements. Different maintenance intervals are scheduled for the drive trains. Three different gear units are included. One gear unit is equipped with a heater and temperature sensor, which causes a maintenance message in case the limiting value is exceeded.
The plant is controlled by a PLC via touch screen. An operating mode and a training mode are available. The training mode is used to simulate time- and sensor-controlled maintenance work. A signal lamp and messages in the PLC indicate the need for action. An augmented reality interface for mobile devices (not included, iPad recommended) is available for visualising the maintenance work. The augmented reality interface also offers extensive additional functions, such as the display of exploded views and data sheets.
The process uses an open design so that all components are freely accessible. At the same time, extensive safety features ensure safe operation. For example, accessible danger areas are protected by light barriers.
QR codes on the gear units allow access to the GUNT Media Center, where extensive technical information is available as didactic multimedia teaching materials, such as a complete set of drawings, 3D drawings or assembly videos. The assembly exercises MT 120 – 123 are available to teach the assembly/disassembly of the gear units themselves.
