Mechatronic Compact Model: Automatic Sorting Line

System

The MCS (Mechatronic Compact System) consists of two individual systems, each with a basic mechatronic function. By connecting the systems, the interaction of mechanics, pneumatics, electrics and PLC Programming is taught.

Learning objectives

• Recognition of different Equipments (sensors)
• Mechanical construction of a test station
• Programming a test sequence
• Mechanical design of a swivelling transducer
• Programming a swivelling transfer unit
• Mechanical setup of a sorting system with three magazines
• Programming a sorting system with three magazines

Structure

The equipment includes two models:

• Drop magazine with inspection unit: Workpieces are separated from a magazine and placed on a tray. The fill level of the magazine is monitored by a light barrier and the workpiece on the tray is monitored by a microswitch. The Equipment properties of the workpiece are determined by means of an optical and inductive sensor.
• Storage in 3 magazines: The workpieces are removed electrically from a previous module with the Pick and Place assembly using a suction gripper and positioned and deposited above the magazines. The rotation speed can be adjusted via the speed controller. 3 magazines can be controlled.

Method

The device is designed as an experiment for pupils and students. Practical tasks challenge the learner to solve the control or system problem with his programme and by means of mechanical settings.

Target group

Vocational training in industry and students specialising in automation technology. The course offers experiments at an intermediate level for vocational schools and bachelor's programmes.
