InnovationsNecessity to design machines introducing technical innovations adapted to the quality requirements of the glass makers:

• Communicating inspection machines allowing remote adjustment and telemaintenance,

• Selectivity of defects at a high speed,

• Automatic and easy job change for a better repeatability

Innovations

Remote maintenance allows :

• remote software updating of inspection machines,

• technical assistance.

Remote adjustment : complete adjustment of the machine by remote technical

centre.

Image processing : more efficient in order to improve the selectivity.

Identification of defects according to shape criteria (density, size, main

direction). It is possible to differenciate a mould seam and a defect for example.

Innovations

Remote maintenance and assistance :

• User friendly thanks to the use of Windows NT4 and XP technologies,

• remote diagnosis and support,

• Software updating,

• Adjustment assistance.

innovations

Quick job change :

1. Using 12 cameras in order to :• Obtain high resolution 100% coverage• Avoid optical adjustments : the fields are fixed and the optical

adjustment is done only once (during the installation of the machine)

• Avoid mechanical adjustment,• Obtain an high resolution analyse even on large containers,• Optimise the observation angle for the neck analyse thanks to an

additional camera• Obtain repetitivety of adjustments• Availability of 4 direct central cameras for a better inspection,• Mix STRESS and TRADITIONAL inspection.

Innovations

Quick job change :

2. Development of a new generation of light sources :

• Characteristics (photometric, geometric) completely driven by computer,

• Universal (same source for the dark glass and the white glass),

• Adapted to any shape.

The image processing

1. Reduction of F.R.R. (False Reject Rate).

Example for body inspection : discrimination between mould seam and vertical tears.

Base and Finish inspection

Finish inspection :

• New patented light source,

• Universal high resolution cameras.

Base inspection :

• Computer driven light source (photometry and geometry),

• Precise detection even at high speed.

Stress Inspection

• Detection of faults with tension in the glass containers base.

EVOLUTION 5

Remote maintenance

• remote technical assistance,

• Repeatability of adjustment,

• Quick job change.

• Experts assistance during job change

Easy installation

•No by pass required,

•Installed over the cullet conveyors

•Centred on conveyor
