Continual improvement
TNPL continues to improve its finishing house operations, with further
automation and computerization of the Work in Process.
The work is already begun for moving from the "existing customized
data interface through PLC" to “Integrated Automation with
Industrial Internet of Things (IIoT)".
◼ Some of such future plans are:
◼ Automatic despatch planning (ADP)
◼ Sheeting plan based on TPA (Truck placement advice)
◼ Customized Deckle optimization program
◼ Automatic Sheeter size change through ERP

Lessons learnt
IPPTA ZONAL SEMINAR 2018
◼ Large initial investment
Automated ,High speed Winders, Rewinders & Reel wrapping machines follow the higher production rates of the Board Machine. Quick ROI for the management
◼ Concept to commissioning Previous product data knowledge, focused objectives are necessary for the basic and detailengineering to correctly select and size the equipments
◼ Higher volume production
At lesser foot print. Increased profitability, to remain competitive and to get the ROI. Satellite centers can be avoided and mill despatch is possible.
◼ Extent of Automation Choose automation depending on the objectives at Reel handling systems, Sheeters, automated ware houses ,ream packing, pallet packing etc.
◼ Extensive training Training the maintenance personnel for operating the automated machines are needed for quick trouble shooting and problem solving.
29
Key takeaways from the FH Automation
◼ Ontime Delivery (OTD) improved beyond 80%
◼ Average service time (Mill to despatch) - 20 – 25 days FOR delivery
◼ Satellite conversion centre is not mandatory
❑ Equipment automation is SUSTAINABLE & RELIABLE
❑ STRATEGIC tool for future challenges.
❑ Automation with ERP interface adds business value .
❑ In house domain expertise is the key.
❑ Effective Design through implementation and efficient execution by Mill team.
