Abstract

L'invenzione si riferisce ad un procedimento ed un dispositivo per il disaccoppiamento dell'azionamento di pinze su macchine per tessere a pinza con elementi a pinza mobili nella boccatura, con gruppo di azionamento di zettatura, con trasmissione a ruote dentate per gli elementi a pinza, con un giunto inseribile per ogni elemento a pinza, con mezzi per la presentazione del filo di trama davanti alle pinze ad ogni ciclo di tessitura, dove gli elementi a pinza, a scelta, possono venire separati dal loro giunto con accoppiamento geometrico con il loro gruppo di azionamento e venire bloccati in una posizione al di fuori della boccatura in posizione di accoppiamento.Avendo come obiettivo quello di realizzare il procedimento di accoppiamento all'interno del normale procedimento di tessitura in maniera affidabile, il procedimento del disaccoppiamento viene configurato in modo tale che in un primo stadio (A) la trasmissione a ruote dentate viene portata nella posizione finale degli elementi a pinza al di fuori della boccatura all'interno del gioco della ruota dentata in una posizione di accoppiamento stabile, successivamente L'elemento a pinza viene bloccato (B), il giunto con accoppiamento geometrico viene connesso (C) e, prima dell'inizio della successiva corsa di introduzione della trama, viene liberato il bloccaggio degli elementi a pinza in senso opposto alla connessione del giunto (D).The invention relates to a method and a device for decoupling the actuation of grippers on rapier weaving machines with movable rapier elements in the spooling, with a zinc-plating drive unit, with gear wheel transmission for the rapier elements. , with an insertable joint for each gripper element, with means for presenting the weft thread in front of the grippers at each weaving cycle, where the gripper elements, at choice, can be separated from their joint with geometric coupling with their drive unit and be locked in a position outside the rewinding in the coupling position.With the aim of realizing the coupling process within the normal weaving process in a reliable way, the process of decoupling is configured in such a way that in a first stage (A) the gearwheel transmission is brought to the final position of the elements a gripper outside the bushing inside the gear wheel play in a stable coupling position, then the gripper element is blocked (B), the joint with geometric coupling is connected (C) and, before the start of the subsequent weft introduction stroke, the clamping of the gripper elements is freed in the opposite direction to the connection of the joint (D).
