Abstract:
Containers in the food and beverage industries are used to package, store and transport ingredients/products. Highspeed capping of containers causes poor/misaligned capping, which affects product quality and leads to leaks. Presently, capping integrity testing is performed either non-destructively inline (e.g. 3D imaging), or offline, using invasive methods (e.g. leak test) but such testing still has room for improvement in time, cost and accuracy. Herein, a capacitive proximity sensor - is used for capping integrity testing to detect uncapped and tilted caps based on the amount of the capping material present in the capacitive field. The sensor showed good detection speed (100 ms) and low detection limits of ~0.11 cm and 0.23 cm for contact and non-contact mode of inspection, respectively.
