Title:
VALVE MODULE STROKE DETECTION
Document Type and Number:
WIPO Patent Application WO/2019/103811
Kind Code:
A8
Abstract:
A valve module stroke detection system includes an adhesive valve module having a reciprocating valve pin. The pin reciprocates in a first direction by application of a compressed gas on one side of a piston and reciprocates in a second opposite direction. The reciprocating pin has a portion in an adhesive flowpath. A sensed element is positioned on the valve pin outside of the adhesive flow path. A sensor is positioned outside of the adhesive flow path. The sensor cooperates with the sensed element and generates a movement signal upon sensing a movement of the valve pin and generates a timing signal upon of the movement of the valve pin. A processor processes the movement signal and the timing signal and a recording medium records the movement signal and the timing signal.
