Smart Conveyor System with Automated Inspection & Reject Handling
Technologies: Rockwell Studio 5000 Logix Designer ยท ControlLogix 5570 Emulator
Key Concepts: Modular PLC Programming ยท UDTs & AOIs ยท FIFO Part Tracking ยท Alarm Handling
๐ Overview
A multi-zone conveyor system that detects, inspects, and automatically rejects defective parts โ built and tested entirely in Studio 5000 with the ControlLogix 5570 Emulator (no physical I/O required).
The project models an industrial inspection line such as those used in packaging or assembly plants.
๐ฏ Highlights
- Auto / Manual Modes โ safe start/stop sequencing and full manual jog control.
- Reusable Motor Control โ
AOI_ConveyorMotorfor each conveyor zone. - FIFO Queue Tracking โ keeps part order from entry to exit.
- Automated Inspection โ checks label, seal, and weight; rejects failures.
- Scalable Alarm Handling โ modular
AOI_Alarmwith trip, latch, and acknowledge. - Structured Codebase โ routines split for IO mapping, modes, conveyor control, inspection, FIFO, and alarms.
๐งช Testing
- Fully simulated and validated in the Studio 5000 Emulator.
- Functional test matrix covers auto start/stop, inspection pass/fail, reject actuation, alarms, and manual jogging.
- No physical chassis or wiring required โ ideal for a learning environment and portfolio demonstration.
