Detect seal faults. Get QA insights. Improve uptime.​

Product in seal detection (PISD)

Available for tna robag® systems, PISD monitors the jaw and seal area in real time to detect faults caused by product in the seal or improper film folding, such as pleats. When a defined number of seal points fall outside preset tolerances, the faulty bag is ejected by the optional reject system — helping reduce waste and maintain consistent pack quality. This ensures only high-quality bags continue downstream.​

PISD also provides insights into how sealing performance is impacted by changes in product and environmental conditions — enabling operators to identify issues and take action in real time. Integrate PISD with your factory data systems to capture live QA insights and traceable, line-wide process optimisation.

  • Detects and logs seal faults in real time to reduce waste and maintain consistent pack quality.​

  • Visually indicates in-seal fault locations in the jaws, and when jaws require cleaning.

  • Ejects faulty bags automatically using the optional reject mechanism — ensuring only high-quality packs move downstream.​

  • Real-time insights into how changing conditions and product is impacting seal quality and consistency.

  • Runs on tna robag® without speed restrictions or additional hardware footprint.

  • When paired with tna intelli-speed, the PISD can be configured to automatically adjust bag-making speed to optimise output, reduce faults, and maximise uptime.

  • Jaw and seal area monitoring with real-time seal fault detection​
  • Detects product in seal and pleats.​​
  • Modbus integration for data logging for QA and performance insights.​​
  • Supports QA traceability and reporting.​​
  • PISD is available as a software function for tna robag® 3, 3c, 3ci and 3e.​

Options

  • tna intelli-speed
    • Optimises bag making speed automatically to reduce faults.
    • Maintains peak output by adapting instantly to product or film changes.
  • PISD reject kit
    • The reject mechanism is an ‘air knife’ that automatically ejects faulty bags from the conveyor when a seal error is detected. Ensuring that only properly sealed bags proceed downstream.
