Application example for preventive maintenance

 Description:

• Preventive maintenance is an indispensable part of Industry 4.0 and helps to avoid unplanned production downtimes.
• MT 174comprises 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 gearboxes are included.
• One gearbox 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 PLCvia 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 PLCindicate 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 gearboxes allow access to the GUNTMedia Centre, 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 gearboxes themselves.
