Hot End

Process Monitoring, Inspection and Control


The ISWatch is a camera system for Hot End process monitoring, inspection and control.

The ISWatch system uses one, two, three or more small sidewall infrared cameras directly placed after the IS-machine. A top camera can be added to further improve the inspection performance, especially the inspection of non-round glass products.

The ISWatch measures from each glass product the following parameters:

  • Glass Distribution
  • Glass Symmetry
  • Glass Temperature
  • Lean / Verticality
  • Diameter / Shape
  • Ware Spacing
  • X and Y Position
  • Rotation angle of non-round products

The cavity related information is displayed in trend graphs together with the infrared images on an easy to use Touch Screen interface.

Warning and alarm levels can be set in order to inform personnel when the glass forming process changes. Direct remedial action can take place in order to produce high quality glass products without defects.

The ISWatch system works with all forming processes (Blow-Blow, Press-Blow and NNPB), all glass colours and with round and non-round ware.

Hot

End Reject



The ISWatch system rejects critical defects like:

  • Fins
  • Bird swings
  • Spikes

By rejecting these critical defects already at the Hot End, it will be prevented they arrive at the Cold End reducing the amount of blocked ware. The ISWatch system warns personnel when such a critical defect is detected in order to act immediately.

The ISWatch rejects also glass products with:

  • Inclusions like stones, bubbles and blisters
  • Thin glass
  • Thick glass
  • Cracks
  • Choked necks
  • Wedged bottoms
  • Lean
  • Shape and diameter problems
  • Freaks
  • Stuck ware
  • Fallen ware
  • And many more..

Industry 4.0

/ Smart Factory



The ISWatch system is fully oriented to Industry 4.0 / Smart Factory, the system stores a quality report of each produced glass product in a database. Customer information systems can be easily connected to the database in order to use the data for production optimization.

All history data can also be retrieved and displayed on the ISWatch system. Issues with the production from days or months ago can be easily tracked and analysed, job runs can be compared and other statistical data analysis can be performed.

Ease

of Use



At Cortex Glass we are closely working together with our customers to improve the performance of our systems and make them easy to use. This continously improvement process has resulted in an ISWatch system which has the following key features:

  • Superior Defect detection algorithms
  • Easy to Use Touch Screen interface
  • Automatic Camera set-up
  • Easy synchronisation to the IS-Machine
  • Self-Explanatory system (limited training necessary)
  • Software options which can be switched on and off

Infrared

Cameras



The infrared cameras of the ISWatch system are the smallest on the market. The small size of the ISWatch camera makes it possible to easily put four or more at the Hot End, making a total hot end inspection feasible.

Cooling of the cameras is easy and can be done with with cooling air or compressed air.

Cortex offers small camera cabinets which can be attached to the conveyor or standing camera cabinets which have a footprint of only 14cm x 14cm.

The ISWatch system integrates seamlessly with the GobWatch, BlankWatch and TopWatch system into the Cortex Glass total hot end monitoring and process control solution.

The ISWatch system can receive and display gob measurements like gob weight and gob temperature from the GobWatch system.

The ISWatch system can receive and display temperature measurements from the BlankWatch system.

With the measurements of the GobWatch and BlankWatch system, it is possible to correlate the glass distribution and glass symmetry with gob temperature, gob weight, mold temperature, plunger temperature, neck ring temperature etc.

Process improvement and optimization will become much easier and effective!

ISWatch

Swabbing Robot Interface



The ISWatch system provides a data interface for closed loop swabbing robot control.

The swabbing robot can be directed to swab a particular mold with the right quantity of lubricant based on the ISWatch measurement of:

  • Glass Distribution
  • Glass Symmetry
  • Bottle Lean
  • Bottle Shape
  • Inclusions
  • Glass Temperature

The closed loop system can also use the information of the GobWatch (gob weight, gob temperature) and BlankWatch (blank temperatures and gob loading) systems to further optimize the robot swabbing process.
