Embroidery machine

Abstract

An embroidering machine is capable of maintaining an unusing balance on a top dead center surely. An embroidering machine comprises: a holding body supporting plural balances(15) and plural needle rods; a color changing device(40) driving one selected from the balances(15) and the needle rods selectively; and a balance maintaining device permitting driving of the selected balance and maintaining the balance not selected on proper position. The balance maintaining device comprises: a correspondent groove(16c) formed on each balance; a lock lever(18) corresponding to each balance, being capable of shaking and inserting a tip(18b) into the correspondent groove(16c) to maintain the balance on proper position; a spring member(20) supporting the lock lever(18) in a direction that the tip(18b) is inserted into the correspondent groove(16c); and a maintenance release device(18c) shaking the corresponded lock lever(18) to extricate the tip(18b) from the correspondent groove(16c).

Description

technical field [0001] The present invention relates to an embroidery machine for selectively using a plurality of needle sticks to form embroidery patterns of various colors on embroidery cloth, etc., more particularly, having a cantilever for holding a cantilever not in use in a prescribed posture Embroidery machine holding device. Background technique [0002] 【Patent Document 1】JP-A-2002-235271 [0003] In the above-mentioned Patent Document 1, there is a description about an embroidery machine for selectively using a plurality of needle bars to form embroidery patterns of various colors on embroidery cloth or the like. In order to keep the unused (non-selected) cantilever at The structure of the top dead center position is ① directly pressed by a spring plate, and ② a structure in which the end of the sliding member capable of advancing and retreating enters and exits the coupling groove provided on the boss of the boom. The structure of the above-mentioned ① has the ...

AI Technical Summary

Problems solved by technology

The structure of the above-mentioned ① has the following problem, that is, when each spring plate is deformed due to the butt joint with the joint release means, due to the torsional force, the elastic force of the spring due to long-term use is weakened.

The disadvantage is that even in a structure that is not subject to such torsion, the spring force of the spring plate is likely to drop, and it cannot be reliably maintained for a long time.

If the cantilever cannot be held in a certain posture, there will be a serious problem that other parts such as the cantilever will be damaged due to the color change action.

In addition, the disadvantage of the structure of ② above is that as a structure for sliding the sliding member, three connecting ring parts are used in total. Therefore, due to the gap between the connecting parts of each connecting ring, not only is it easy to generate movement errors, but also the cost is increased.
