Weaving machine equipped with piezoelectric element

Abstract

(57)【要約】 【課題】 ナイフによって上昇させられる縦針や糸キャ リヤ等の昇降部材に対し、電圧の印加により湾曲する圧 電素子を利用して選択部材を二位置に切り換え、昇降部 材を選択的に保持させるようにした織機において、選択 部材と昇降部材との係合を正確に行わせること 【解決手段】 薄肉金属板と圧電磁気とを積層させたバ イモルフ型の圧電素子を使用し、少なくとも圧電磁気と 支持壁との間に導電ゴムを介在させた状態で圧電素子を 取付具に支持させ、基板上に設けた接続部に導電ゴムを 当接させた状態で取付具を基板に固定する
PROBLEM TO BE SOLVED: To secure exact connection between a selection member and a lifting member in a weaving machine in which the lifting member that is lifted by a knife, for example, a hook, a yarn carrier, and the like, is switched its positions from one to the other by using a piezoelectric element capable of curving by applied voltage in order to selectively hold the lifting member. SOLUTION: A bimorph type piezoelectric element prepared by laminating a thin metallic plate to a piezoelectric ceramic is used and the piezoelectric element is supported with an attachment in the state where an electroconductive rubber is intervened at least between the piezoelectric ceramic and a supporting wall and the attachment is fixed to a base plate in the state that the electroconductive rubber is brought into contact with a connection part provided on the base plate.
