nScan empty-glass inspection

Every bottle inspected before it reaches the filler

Whether 15,000, 40,000 or 120,000 bottles per hour: nScan adapts to your line and detects foreign objects, broken glass and shape defects on new and returnable glass bottles – in real time, right on the conveyor.

Inspection tasks

From base to finish

A single glass splinter in the base or a chipped finish can become a risk to consumers and your brand once the bottle is filled. nScan inspects every bottle – new glass or returnable – at all critical points and rejects defective bottles before they are filled.

Bottle base with a marked glass splinter

Foreign object detected

Base inspection

Glass splinters, yeast residue, foil fragments or dirt: anything that doesn’t belong on the bottle base is reliably detected.

Bottle finish with a marked chip on the thread

Chip detected

Finish inspection

Chips, cracks and damaged threads compromise the seal of the closure. nScan finds them before the bottle enters the filler.

Foreign bottle detected

Foreign bottle detection

Bottles of the wrong shape, size or color are identified by their contour and color and rejected.

Bottle silhouette under backlight with height measurement and center axis

Tilt detected

Geometry inspection

The height, contour and position of every bottle are compared with the trained good sample – deviations such as tilt stand out immediately.

Sidewall of a glass bottle with a marked crack

Crack detected

Sidewall inspection

The bottle wall is checked for cracks, scratches, air bubbles in the glass and leftover label residue.

Mold number on the bottle base, each character detected and read

Code read

Markings and codes

Mold numbers, dot codes and other embossings in the glass are read automatically and made available for analysis.

FAQ

Frequently asked questions

Empty-glass inspection

Which defects does nScan detect on empty glass bottles?

nScan inspects the base, finish and sidewall: foreign objects, broken glass, yeast and dirt residue, chips on the thread and sealing surface, cracks, scratches, air bubbles and label residue. The system also detects foreign bottles, geometry defects such as tilt or incorrect height, and markings such as mold numbers and dot codes.

How many bottles per hour can nScan inspect?

nScan is matched to the speed of your line – whether 15,000, 40,000 or 120,000 bottles per hour. Inspection takes place in real time, right on the conveyor.

Is nScan also suitable for returnable bottles?

Yes. nScan inspects new and returnable glass bottles and rejects damaged or dirty bottles before they reach the filler.

How much effort does it take to teach in new bottle types?

With Teach & Go, nScan is taught in a few minutes using one good sample – no programming required.

Can nScan be integrated into an existing bottling line?

Yes. nScan is installed in existing filling and conveying systems and communicates with the line control via PROFINET, EtherCAT and OPC UA.

Is image data transferred to a cloud?

No. The AI analysis runs directly at the line. No cloud connection is required.
