The principle of the Gob Image Analysing function is based on a line scanning technique, which allows even very long gobs as well as velocity to be measured.
All collected data
The operating staff is able to follow the behaviour of the gob throughout the entire forming process. The machine operator can make adjustments on the operator’s panel without being exposed to heat and noise. Production problems can be analysed at a very early stage for immediate action, allowing operators more time for quality control etc.
Higher resolution, better image accuracy
By using a 1024 pixel scan line array a high resolution is obtained. The higher sensitivity of the array is also essential when measuring e.g. small flint gobs.
Full 256 grey-scale analysis
The possibility to mapping grey-scale to customized colours gives the operator better insight into the gob properties. Anomalies as well intermittent discrepancies in the gob process can be identified. For repeat production runs, the image also facilitates the setting up of the same conditions as the previous operations.
Camera
The GIA camera is equipped with a pneumatic vortex cooler, providing cooling of the camera as well as heating of the lens system to prevent condensation. Overpressure in the casing keeps dust and oil away. As an option, the camera can be installed at e.g. blank position, which means that the gob image comparison can be made between shearing and delivery position. To make installation simple, the dimensions of the camera have been adapted to suit the available space.
Central Unit
One central unit can support up to four cameras, allowing a variety of different applications with multiple camera configuration for DG, TG and QG operations. The Central Unit (CU) consists of simple compact enclosure housing disk drives and electronics assembled on a mounting panel. Optionally, the unit can be installed in an existing cabinet at a remote position. Information on the gobs is displayed on a high-resolution colour screen.
