Hot End sensor solution for monitoring and controlling of gob loading and temperature

The GobAssist-BTC assists container glass and tableware manufacturers to improve their product quality and increases the glass forming process capabilities by monitoring and controlling the gob loading combined with temperature measurements of the blank mould, neck ring, plunger and parison for each individual cavity.

operating principle

The GobAssist unit observes the gob trajectory after the gob exiting the deflector until it enters into the blank mould. With two high speed camera gob speed, length, time-of-arrival, loading position and gob shape are measured. Moving the camera unit continuously from section to section these measurements are repeated every 15-20 minutes.

In the same unit the BTC (Blankside Temperature Control) measures temperatures of mould materials and – uniquely – of glass as well. Of each cavity it measures one or more positions on the blank mould, neck ring, plunger and parison.

A simple user interface allows for real time corrective action. At the same time the effect on the glass distribution of the product is visualized by IR-D system.

The GobAssist-BTC ensures to find, to maintain and to retrieve the optimal loading and temperature distribution within seconds, eliminating two most important sources of process variation and minimizing critical defects related to bad loading or bad temperature distribution.

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 in combination with other production data from furnace, feeder, Cold End inspection and laboratory systems. Uniquely the XPAR Vision GobAssist-BTC is integrated with major IS-machine timing systems to enable closed loop interfaces for automatic Mould Cooling and Glass Distribution control.
