The IGC – Infrared Gob weight Control system – is an add-on to XPAR Vision’s IR-D infrared camera system that assists container glass and tableware manufacturers to increase their glass forming process capabilities by controlling the weight of all cut gobs automatically.
This innovative solution is suitable for all forming processes (Blow & Blow, Press & Blow and NNPB) and for round and non-round ware in each glass colour.
At the Hot End XPAR Vision’s IR-D system detects the intensity of infrared radiation emitted by each single hot glass product. The IGC system relates this measurement to the weight of the corresponding gob. Any deviations in gob weight are automatically compensated by the IGC in adjusting the position of the tube and/or the needles.
The IGC ensures a constant weight of each individual gob, thus eliminating an important source of process variation.
The simple and intuitive user interface notifies the operator automatically to weigh the product when needed, in order to reconfirm the weight to intensity correlation.
A special Start-up mode allows for a quick and accurate Job Change execution.
The IGC enables access for any user in the company’s network to review the status of the forming process and the quality of the glass products.
open data interface
XPAR Vision enables open data connections to standard and proprietary Production Information Systems to present and correlate real time hot end information with other production data from furnace, feeder, Cold End inspection and laboratory systems.
Uniquely XPAR Vision teams with major IS-machine manufacturers to provide closed loop interfaces with OEM Feeder systems for automatic weight control of the individual gobs.
