Electronic jacquard device and cassette for electronic jacquard

Abstract

An electronic jacquard device capable of securing a stable needle selecting operation over a long period and the stable operation of a select hook even when the tip of a needle touches the tip of the select hook and a cassette for an electronic jacquard. The electronic jacquard device comprises the select hook swung between an engagement attitude for engagement with the needle and a non-engagement attitude for non-engagement with the needle for attitude selection by the bending of an operation body formed of a piezoelectric element body, and a holding pin forming the swing pivot of the select hook. The holding pin is formed separately from a cassette body, and the holding pin is supported by a holding plate which holds the cassette on a jacquard body.

Description

technical field [0001] The invention relates to an electronic jacquard device and a box for the electronic jacquard device installed and used on the jacquard device. Background technique [0002] The Jacquard device is used to control the position of a plurality of threads mounted on a frame, for positioning the needles that process the individual threads or threads in strands. Here, the needles provided on the frame are loaded in the direction of their length and towards the direction away from the jacquard device. [0003] On the other hand, the main body of the jacquard device is provided with a reciprocating mechanism that reciprocates the main body of the jacquard device along the longitudinal direction of the needle. The relative positional relationship in the above-mentioned length direction changes. When the main body of the jacquard device and the needle are in the initial position at the same time, the above-mentioned needle selection hook can be engaged with the...

AI Technical Summary

Problems solved by technology

[0015] However, in the electronic jacquard device in the prior art, the selector hook adopts a structure supported by a holding pin erected on the box body, and the holding pin is a resin product made of the same material as the box body, so , the problem is that the root of the upright setting of the holding pin is broken, etc., which will cause it to fail to perform its original function as a holding pin

[0016] In addition, in terms of the top shape of the needle selector hook, the top surface of the needle selector hook in the prior art is a surface perpendicular to the length direction of the needle, so , when the top of the needle is in contact with the top of the needle selector hook, it will make an action that hinders the swing of the needle selector hook
