Automatic Capsule Filling Problems That Affect Production Efficiency — And How to Fix Them
High-precision automatic capsule filling machines like the NJP800C are the backbone of modern pharmaceutical production lines. However, during daily operation, three common problems may occur that directly impact output, quality, and uptime. Below is a practical troubleshooting guide to help engineers and operators quickly identify and resolve these issues.
Capsule Misalignment & Feeding Issues: Causes & Solutions
Problem 1: Improper Adjustment of the Capsule Feeding Platform
Symptoms
During the capsule feeding and separating step, empty capsules may shift sideways, jam in the guide rails, or fail to seat properly in the filling die, resulting in misaligned or rejected capsules.
Solutions
✅ Adjust the guide rail width
Verify that the capsule guide rail width is 0.5–1 mm wider than the capsule shell.
Too tight → Capsules become jammed or damaged during transport.
Too loose → Capsules shift left/right, causing misalignment in the die.
✅ Ensure accurate capsule orientation
Check the capsule sorting mechanism and vibratory feeder to ensure consistent orientation of cap and body.
✅ Check the clamping and indexing system
Confirm the filling platform cylinder clamps the capsules firmly at the end of the indexing stroke to prevent movement during dosing.
