Preventive maintenance is an indispensable part of Industry 4.0 and helps to avoid unplanned production downtimes. The laboratory-scale MT 174 sorting plant comprises a separation process that serves as an application example for various maintenance tasks. The plant is equipped with standard industrial components.
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 (Vuforia View) 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. For device-independent use of augmented reality, 3 miniature models of the sorting plant are included in the scope of delivery.
The process uses an open design so that all components are freely accessible. Extensive safety equipment, such as light barriers in accessible danger areas, ensure safe operation. For the removal and installation of the gear units, the plant has a crane that can be set up in three different positions.
Extensive technical information is available as didactic multimedia teaching materials in the GUNT Media Center, such as a complete set of drawings, 3D drawings or assembly videos. The assembly exercises MT 120 to MT 123 are available to teach the assembly/disassembly of the gear units themselves.
