VISCONT.Roll materials

Quality control system for roll materials

VISCONT.Roll materials is a system that provides visual quality control of roll materials of various types with the preservation of information on detected defects. State-of-the-industry defect detection in the film production process enables to adjust quickly the line settings in order to reduce or eliminate the appearance of defects in the material.

The system allows to identify the following types of defects:

  • holes with 1 mm length;
  • cuts;
  • foreign inclusions;
  • glue drops;
  • riffles and creases.

The hardware part of the system includes:

  • linear camera for machine vision;
  • specialized illuminator;
  • encoder.

PC with VISCONT software installed.

VISCONT software receives images from a linear camera before winding the web into a roll. Video analytics algorithms process the received images for defects.
For each detected defect, the system saves the following parameters:

  • coordinates (X,Y) of the defect on the web;
  • area of the defect;
  • image of the defect.

Automated workstation of system operator provides an opportunity:

  • to start and stop the control process with an indication of the type of material;
  • to view the current image of the material online, all defects detected on the web are highlighted by the system;
  • to generate a scalable roll map that displays all defects;
  • to view the archive of data on detected defects according to the roll number, type of film and date of production (rewinding);
  • to upload data on defects in xml, csv formats, etc.

Additional system’s capabilities:

  • to perform additional training of video analytics algorithms for new types of film;
  • to set the minimum allowable values of parameters for detecting defects;
  • to transmit and receive control actions in VISCONT (for example, start and stop) from the process control system of the production line;
  • to transmit data on detected defects for each roll to the inspection line;
  • to create and manage user accounts.
