Abstract

"PROCESSO PARA O COMANDO DE COMPONENTES DE UM MEIO DE TRABALHO EM TEARES AUTOMáTICOS E TEAR AUTOMáTICO PARA A EXECUçãO DO PROCESSO". A invenção refere-se a um processo para o comando de pelo menos um componente que executa uma função de trabalho, por exemplo, uma pinça do fio de trama (1) como meio de trabalho de um tear automático. Com uma pinça de do fio de trama, o componente (2) é previamente tencionado mecanicamente mediante uma alavanca (5), acionada do lado de fora, e mediante uma mola (6) configurada como acumulador de energia e disposta no corpo da pinça do fio de trama. Uma peça (9) unida ao componente (2) é guiada axialmente em um elemento de atuação (11) que exerce um efeito de aperto sobre a peça. O elemento de atuação (11) é atuada por uma energia auxiliar de tal maneira que o componente (2) é fixado, a um primeiro momento, na posição previamente tencionada sendo fechado o pegador de fio (4) e a um segundo momento é abolida a tensão prévia abrindo nesta ocasião o pegador de fio (4)."PROCESS FOR COMMANDING COMPONENTS OF A WORKPLACE IN AUTOMATIC TEARS AND AUTOMATIC TEAR FOR CARRYING OUT THE PROCESS". The invention relates to a method for controlling at least one component which performs a working function, for example a weft tweezers (1) as a working means of an automatic loom. With a weft tweezers, component (2) is previously mechanically tensioned by a lever (5), which is operated outside, and by a spring (6) configured as an energy accumulator and disposed in the body of the tweezers. weft thread. A part (9) attached to component (2) is axially guided in an actuation element (11) which exerts a clamping effect on the part. The actuation element (11) is actuated by an auxiliary energy such that the component (2) is fixed at a first moment in the previously intended position when the wire harness (4) is closed and at a second moment is abolished. the previous tension by opening the wire harness (4).
