Gob
Monitoring, Inspection and Control
The GobWatch is an innovative gob monitoring, gob weight control and gob inspection system.
The GobWatch system uses two high resolution cameras to create 3D images of all gobs from single, dual, triple or quad gob feeders.
The gob weight control function of the GobWatch system is very precise (±0.05% achievable) and works with single weight and multi weight gob feeders.
The GobWatch system can automatically reject glass products with
gob weight deviations, gob length deviations, gob falling angle deviations or flint glass gobs with inclusions.
The GobWatch system comes with different options, is easy to use, improves the quality and productivity, shortens the Job-Change time and has a fast payback time.
Gob
Monitoring
The 3D gob images are processed and analysed in real-time in order to monitor the following parameters:
Gob Reference, gob width, gob length and gob weight graphs
- Gob Weight
- Gob Diameter
- Gob Length
- Gob Speed
- Gob Shape
- Gob Falling Angle X-direction
- Gob Falling Angle Y-direction
- Gob Temperature
- Gob Temperature Profile
- Seed Count and Bubble Count (flint glass)
- Inclusion Size (flint glass)
All measured parameters are stored and displayed in trend graphs.
Automatic
Gob Weight Control
Controller screen (Tube Height, Weight Distribution, Gob Weight graphs)
The GobWatch system automatically controls the gob weight by making small adjustments to the tube height, individual plunger height or tube rotation speed.
The gob weight control can start directly after a job change.
Seed,
Bubble and Stone Inspection
Seed count, bubble count and size distribution graphs
The GobWatch system inspects each flint glass gob for seeds, bubbles and stones.
The seed count and bubble count information is stored and shown in
various trend graphs.
Hot
End Reject
Rejects screen
The GobWatch system automatically rejects glass products made from gobs with
gob weight deviations, shape deviations, temperature deviations and drop angle deviations.
The system can also reject a glass product made from a flint glass gob with a bubble, blister, cord or stone directly after the IS-machine.
Industry 4.0
/ Smart Factory
Statistics screen
Measurement data of each glass gob is stored in a database and can be easily retrieved and displayed on the GobWatch system.
The measurement data is available for other systems to further improve the production process (furnace, forehearth etc).
