Open pageLight inspection machines for filled bottles
Light inspection provides a controlled viewing or detection point for filled containers. It can support checks for visible foreign matter, fill level, bottle condition or closure appearance, but the defect list and detection method must be agreed. The term inspection machine does not by itself mean that every defect is automatically detected or rejected.
Position in the packaging line
Possible locations include:
- After filling and before closure, when the open product can be inspected safely
- After capping or sealing, for a combined liquid-level and package check
- Before labeling, when the bottle wall needs to remain visible
- Before case packing as a final operator or automated inspection point
The location affects lighting, bottle rotation, contamination control and the type of rejection system that may be required.
Define the inspection task
A purchase specification should state:
- Product color, clarity and expected natural variation
- Bottle material, tint, wall pattern and label-free viewing area
- Defects to be checked and representative defect samples
- Manual visual inspection or sensor/camera-based function
- Required bottle rotation, spacing and background
- Reject confirmation and collection scope, if any
- Data recording or line-stop signal requirements
Product entry
| Model | What to verify |
|---|---|
| Automatic light inspection machine | Lighting arrangement, bottle presentation, inspection scope and line interface |
Use the linked page for published model information. Detection performance requires an agreed defect set, approved containers and a documented test protocol.
Procurement decisions that affect price
- Viewing conveyor, assisted inspection or automated detection scope
- Bottle rotation and stabilization method
- Lighting, enclosure and operator workstation
- Reject mechanism, reject confirmation and collection area
- Controls and communication with filler, capper or labeler
- Number of formats, destination power and service scope
Quote request checklist
Send filled and empty bottle samples, good and defective reference samples, product description, target output, inspection position, upstream/downstream equipment, required reject logic, data needs, layout, utilities and destination. Identify defects that are safety-critical and the validation responsibility for each.
FAT and after-sales boundary
FAT should use the agreed good and seeded-defect samples under a written challenge method. Record detection or operator-visibility criteria, false rejects where applicable, bottle transfer, changeover and interlocks. Validation, local quality approval, installation, travel, training, spare lights or sensors and support terms must be explicitly priced and contracted.
