Foreign Particle Inspection Flosta

The full bottle foreign matter integrated inspection machine is an online device deployed after filling, which comprehensively inspects foreign objects inside bottles, liquid levels and cap quality, and rejects defective products. It features flexible configuration; suitable modules can be matched according to manufacturers’ actual requirements. With high integration and simple operation, it delivers consistent stable inspection performance for production lines.


Scope of application:

Glass Bottle

Installation Location:

After Pasteurizer

System Introduction

The integrated full bottle foreign object inspection machine is an online inspection unit integrating inspection functions for in-bottle foreign objects, liquid level, cap quality and more.Machine dimensions: 2515×972×2200 (L×W×H).

Equipped with the XispVision inspection platform, it detects suspended foreign bodies inside filled bottles and debris at bottle bottoms after filling. Detectable contaminants include bent paper clips or wires, cigarette packs, cigarette butts, razor blades, beverage straws, crown caps, can pull tabs, O-rings, etc. Its detection rate reaches 99.9%, and liquid level inspection tolerance is controlled within ±1 mm, making it an extremely reliable inspection device.
Electric height adjustment is adopted to enable one-click product model switching.


Inspection Items

Foreign matter inspection: suspended foreign bodies, bottom debris

Liquid level inspection: high/low liquid level (X-ray optional)
High & tilted cap inspection: missing cap, raised cap, tilted cap, full 360° coverage for caps
Print code inspection (temperature sensor can be retrofitted)
Cap top LOGO inspection
Filling Management System (FMS)

Suspended Foreign Particle Inspection

The inspection of suspended foreign objects consists of two inspection stations: bottle body inspection at the infeed side and bottle body inspection at the outfeed side, equipped with a total of four industrial cameras.
First, bottles pass through the inspection module at the infeed side. Then differential speed of two drive motors rotates each bottle by 90°. A second inspection is carried out by the outfeed-side inspection module to achieve full omnidirectional scanning of the bottle body.
The bottle inspection module features a special layout with mirror reflection technology. This eliminates image interference caused by uneven glass thickness or embossed patterns, while expanding the field of view for each individual camera. As shown in the diagram, the bottle body is captured from two distinct viewing angles.

Bottom Foreign Particle Inspection


The bottle bottom foreign object inspection is equipped with three high-speed industrial cameras. A trigger photoelectric sensor is additionally fitted in front of each camera for precise camera shooting triggering.
As bottles pass through the bottle bottom inspection module, each camera captures 3 to 4 images. Bright-field and dark-field lighting modes are applied to detect transparent and opaque contaminants respectively. For dark-field inspection, low-angle side lighting is used to take multiple shots for identifying reflective transparent foreign matter such as glass fragments. Bright-field inspection adopts front lighting with one shot to detect opaque debris on the bottle bottom.
To minimize interference from lubricant residue on bottle bottoms, the machine is fitted with an automatic air-blow cleaning device for bottle bottoms, ensuring high inspection accuracy.


Cap Inspection

This function mainly inspects crown caps for missing caps, over-height caps, under-height caps, tilted caps and deformed caps.

The cap inspection system is equipped with three industrial cameras and maintenance-free long-life white LED lights. Backlight shooting is adopted to improve image contrast. Combined with a precision optical reflection system, it realizes 360° full inspection of crown cap profiles and rejects products with tilted, missing or deformed caps. The inspection accuracy for tilted and over-height caps reaches ±1 mm.
For simple presence/absence detection of crown caps, the optional crown cap inspection module S (KKI-S) is available.

Fill Level Inspection


It mainly inspects the liquid level inside bottles. High-resolution cameras and custom light reflectors are used to distinguish between normal and abnormal liquid levels.

The liquid level inspection unit consists of one industrial camera and maintenance-free infrared LED lights. The strong penetrability of infrared light enhances image contrast. Meanwhile, the XispVision inspection platform accurately calculates liquid level by comparing height differences on both sides. It eliminates the impact of uneven liquid surfaces during high-speed conveying and delivers an inspection accuracy of ±1 mm, ensuring efficient and stable system operation.
X-ray liquid level inspection is available as an option, which is suitable for opaque containers such as cans.

Code Presence

It mainly inspects the presence or absence of product codes and is compatible with all common inkjet and laser coding machines.

The inspection accuracy reaches 99.9% for codes that are completely missing or worn away by more than 70%.

Top Logo Inspection

It mainly checks caps for missing top logos and wrong-colour patterns to identify abnormal caps. Constructed from grade 304 stainless steel, it complies with hygienic production standards.
The cap-top logo inspection unit consists of one colour industrial camera and a ring-shaped LED light source, which identifies faulty caps based on pattern and colour differences. Besides, it judges cap damage via roundness measurement, adding an extra safeguard for cap inspection.

Filler Management System

Combining the inspection system with the real-time tracking system links statistical inspection data to the positions of filling valves inside the filler and capping heads. Each filling head and other equipment requiring traceability is fitted with a photoelectric sensor. Triggering of the sensor creates an independent monitoring channel for corresponding products, which closes upon product rejection to achieve full-lifecycle tracking.

If a specific filling valve repeatedly delivers underfilled products or a certain capping head continuously produces tilted caps, the system automatically alerts operators for targeted maintenance. This facilitates predictive maintenance at the plant, cuts downtime and improves production stability.
Moreover, the filling management system enables online pre-inspection against bottle bursting to block defective bottles with hidden cracks, preventing high-pressure breakage during filling, machine jamming caused by broken glass and product contamination.
Custom sampling is also supported with flexible configurable sampling rules: for example, extracting 10 sample bottles from a designated filling valve or bulk sampling from all working stations. The system runs sampling automatically after simple parameter entry, delivering high efficiency and greatly improving overall product quality.
