Automated industrial belt conveyors

Educational objectives
• To observe and understand the operation of an industrial belt conveyor.
• To take industrial measurements of electrical values.
• To study the operation of inductive and photo-electric sensors.
• To study the reversal of the rotation direction of an asynchronous motor.
• To study the speed control of an asynchronous motor.
• To learn how to wire the different components available on a belt conveyor (detector and light column).
• To study the programming of a controller (PLC) with analogue output signal 4-20mA/0-10V.
• To study the programming of an HMI screen with supervision software.
• To study Ethernet / IP addressing
• To perform industrial maintenance operations.

Composition
• Industrial belt conveyor driven by three-phase asynchronous gear motor 3x400VAC. Useful surface area of the conveyor 1400x370mm (x1 for CONV-1S / x2 for CONV-2S)
• Photo-electric sensors with adjustable fixing.
The sensors can be moved along the conveyor.
Output with DRY, NO contact (x3 for CONV-1S / x5 for CONV-2S)
• Inductive sensor with adjustable fixing.
The sensor can be moved along the conveyor.
Transistor output (x1 for CONV-1S / x2 for CONV-2S)
• One light column with three colours.
• One electrical cabinet equipped with a wiring frame composed of:
- one set of circuit-breakers
- one set of contactors
- one Schneider® M221 controller with analogue board 4-20mA and 0-10V.
- Ethernet RJ45.
- one Schneider speed variator equipped with its Somove software
- one set of terminal blocks
- one Ethernet switch
• One Ethernet colour HMI touch screen 5.7’’ with its Vijeo Designer® software.
Mounted on an easy-to-move arm. The screen is easy to unplug from its support for easy storage.
• Tray at start and end of conveyor to collect the conveyed articles (x2 for CONV-1S / x3 for CONV-2S)
