Troubleshooting and maintenance for automatic capsule filling machines — capsule feeding and separation, powder dosing and fill weight, closing and locking, capsule defects, vacuum and air, drives, electrical alarms, cleaning and changeover.
Faults between the empty-capsule hopper and the separation station: capsules that will not feed, orient, seat in the tooling or separate cleanly into cap and body.
Faults in the dosing station, tamping pins and powder feed that affect whether capsules are filled, and how accurately.
Faults that start with the powder itself or the room conditions. Capsule fillers dose a fixed volume, so anything that changes density or flow changes fill weight.
Faults at the closing station: capsules that stay open, lock partially, telescope, or are damaged as they close.
Visible defects on finished capsules and faults at the discharge and rejection stations.
Utilities that drive separation, locking, pneumatics and dust control. Many faults elsewhere in this manual trace back to this section.
Faults in the main drive, indexing and transmission. Stop the machine at the first sign of abnormal noise or vibration rather than running through it.
Electrical work must be done by authorised personnel with the supply isolated and locked out. Always record the alarm code before resetting.
Quality-system events. Each requires production to stop, affected product to be controlled and QA to be involved before restart.
A dosing-disc capsule filler is a volumetric machine. It carries empty capsules through a fixed sequence of stations on an indexing turret, filling each capsule body with a compacted powder slug of fixed volume. Understanding the sequence makes it easier to locate where a fault starts.
