This technology is the laser spectroscopy technology, which can provide multiple advantages: measurement of the gas concentration inside the package without the need to pierce and then dispose it, inspection of the proper sealing in the entire welding area at full line speed, non-destructive monitoring on 100% of production, optimization of the production process and identification of packaging anomalies.
Among our applications, the LDS 700-IoT inspection system is certainly the one that attracts the most attention. Designed to provide the food industry with an "in-line" inspection system capable of detecting micro-holes at full speed on 100% of production, it is characterized by the high reliability of its measurements.
The speed of measurement and its high sensitivity allow the gas leaks detection from containers packed in MAP (Modified Atmosphere Packaging).
The measurement is performed directly in line, on output products from the packaging machine, with the packages moving on the conveyor belt, compatibly with the existing line speeds.
The system is able to perform the in-line leak detection thanks to a soft pressure applied to the packages by extremely soft rollers that generate, in the presence of holes, the exchange of gas with the outside. The gas detection sensors with spectroscopic techniques are located near the packet in transit. The presence of CO2 inside the package allows leak detection without the need to use a specific tracer gas.
An innovative engineering solution also makes it possible to identify the area of the packaging where defects are detected, giving feedback to the customer in the event of systematic defects and locating which steps of the packaging process should be optimized through targeted maintenance.
