Automatic in-line Inspection System of Thermoformed Containers

Plastic containers for food

How does it work?

  • The system analyses thermoform defects presence during manufacturing cycle time by means of computer vision and AI techniques.
  • It is directly connected to the thermoforming line in order to synchronize the necessary signals for the proper operation of the inspection system.
  • When one or several defective thermoforms are detected, the system identifies them on the HMI and activates an alarm using a beacon and an acoustic signal.
  • The acceptance or rejection criteria can be adapted to the specific needs of each client.
  • Upon detection of a defect, the system sends a signal to the thermoforming machine and the defective parts can be segregated using different methods depending on the machine configuration.
  • The system shows them on the HMI and the inspection history can be checked in order to extract conclusions at a later stage.

What does our system guarantee?

  • Inspection within cycle time.
  • Data analytics in real time in order to take in-line decisions.
  • Analysis of product defects.
  • Photographic documentation of defective thermoforms.
  • In-line removal of non-compliant products.
  • Export of inspection results to most commonly used formats.
  • Taking corrective actions during the production stage.
  • Significant reduction in costs associated with non-quality products.
  • Avoid Customer penalties.

Our system is designed to identify defects in the thermoforming process

  • The presence of foreign objects/ contamination on the thermoforms: Dirt, metal parts, cracks, holes, bits of plastic, black points, hairs, bugs or contamination.
  • The presence/absence and position of the pad inside the thermoforms (trays) and its position.
  • In case you work with glue coating:
    • Incorrect application of the glue film on the trays contour during the production process.
    • Bald spots or areas without glue on the trays contour.
    • Balls of glue.

The system is ready to detect defects in any type of plastic and in any colour (PET, HDPE,PVC, LDPE, PP, PS and PAPER).
