Overview of TechnologyOverview of Technology
Our Infrared Flaw Detection Technology offers quality inspection of web based materials for holes and various visual defects (i.e., bugs, oil, dirt and scale). our infrared defect detection technology has all of the system electronics contained in one single NEMA rated free standing console. Generally located near the tender control stations, this integrated control unit facilitates both installation (by eliminating the need for several time consuming connections) and operation (by improving accessibility and maintenance through the consolidation of all components into one location). Lamp driver circuitry, sensing and noise reduction circuitry, power supplies, sensitivity controls, output processing systems and audio/visual alarm and system software displays are located inside the enclosure.

Operation: Using an array of phototransistors located very close to the web material surface at 1 inch (25mm) intervals (cross direction), the photo cells monitor the intensities of infrared light. The phototransistors are mounted on interchangeable PCB modules in an air purged inspection enclosure. Each inspection module consists of 6 transistors that cover 6 inches (15.24cm) of cross direction web. Each module is a quick connect with various test points for easy and complete system check and maintenance.

A Narrow inspection aperture, typically 1/32" (0.8mm) wide in the machine direction limits the "field of view" of each phototransistor. This FOV reduction technique reducing formation noise normally created by unblemished material to assure a high "signal to noise" ratio. The inspection aperture also acts as an ambient light prohibitor.

Distinguish between sizes of defects: Defect size classification are standard in all technologies and allow for the removal of larger defects considered rejectable from salable product. Additionally, the detection and monitoring of the smallest possible defects allow production the ability to monitor process machine performance, schedule proper preventative maintenance of defect causing areas and allow for production grading of material should a threshold of small defects per roll exceed a present quality limit. All defects are classified, channelized and separated into individual reporting algorithms with location in both the cross machine and machine direction, time the event took place and size of the event.

Add Analysis and Reporting: Our Quality Assurance Management System (QAMS) software ToolPack also is included with each system and provides detailed information on overall production of the machine. Repeating defect detection capabilities are included with each Flaw Detection System. This feature enables operators to quickly located the source of the repeating defect such as wire holes, damaged fabrics and roll decomposition. Every repeating defect will be displayed on the monitor and will indicate location in both machine and cross machine direction.

Installation areas in most cases are prior to the take up reel (commonly referred as the jumbo roll) at the end of web material processing. Most installations should be after the basis weight gauging unit as picking can occur from gauge guides.
