Abstract
Sistema di controllo qualità del filato associato a filatoi o ritorcitoi in cui il filo (12) coopera a con un riccio guidafilo (11) montato solidalmente su un braccio (14) porta riccio guidafilo (11) ancoratesi alla struttura della macchina, prevedente almeno un sensore piezoelettrico (13) associato solidalmente al detto braccio (14) porta riccio guidafilo (11), detto sensore piezoelettrico (13) essendo associato ad un dispositivo di elaborazione e controllo (17) che elabora il segnale generato dal detto sensore piezoelettrico (13) generando un segnale elettrico (16) di tipo sinusoidale con ampiezza proporzionale alla tensione del filo (12) e frequenza proporzionale alla velocità di rotazione del ballon.Dispositivo di controllo qualità filato idoneo ad essere integrato nel sistema di cui sopra comprendente un braccio (14) ancoratesi alla struttura della macchina e riportante solidale il riccio guidafilo (11), detto braccio (14) essendo associato longitudinalmente e solidalmente ad un sensore piezoelettrico (13).Quality control system of the yarn associated with spinning or twisting machines in which the yarn (12) cooperates with a yarn guide hedgehog (11) mounted solidly on an arm (14) yarn guide hedgehog holder (11) anchored to the machine structure, comprising at least one piezoelectric sensor (13) integrally associated with said arm (14) curly thread guide holder (11), said piezoelectric sensor (13) being associated with a processing and control device (17) which processes the signal generated by said piezoelectric sensor (13) generating a sinusoidal electric signal (16) with an amplitude proportional to the thread tension (12) and a frequency proportional to the rotation speed of the balloon. Yarn quality control device suitable to be integrated in the above system comprising an arm (14) anchored to the structure of the machine and bearing the wire guide hedgehog (11), said arm (14) being associated longitudinally and integrally with u n piezoelectric sensor (13).
