Automated Liquid Filling Line
PLC-controlled liquid filling machine with level sensing, safety interlocks and HMI recipe handling.
Overview
A production liquid-filling machine built and commissioned for an industrial client. The line handles bottle indexing, volumetric filling, capping interlocks and operator recipe selection through an HMI.
Problem
Manual filling produced inconsistent volumes, frequent spillage and no traceability of batch output.
Solution
Designed a PLC control scheme with photoelectric bottle detection, timed/volumetric dosing valves, emergency-stop safety circuit and an HMI for recipe and batch counters.
Engineering process
Requirement capture on the shop floor, electrical schematic design, panel wiring, PLC program structure with parameterised function blocks, dry testing, then commissioning and operator training.
Results
Fill accuracy within tolerance across batches, reduced spillage and a repeatable changeover procedure between bottle sizes.
