Embodiment Construction

[0081] Embodiments of the threading device in the embroidery sewing machine of the present invention will be described below with reference to the accompanying drawings.

[0082] Such as Figure 1 ~ Figure 2 As shown, the sewing machine for embroidery is composed of a plurality of sewing heads 1, a thread supply and recovery device 2, a thread take-up mechanism 4, a threading device 5 and the like to form its main parts.

[0083] The figure of the present embodiment schematically shows a part of the sewing machine head provided with about 30 heads in the case of a large number of heads in one embroidery sewing machine. Moreover, other sewing heads other than those shown in the illustrations also adopt the same structure as the embodiment, and at the same time, they are made to synchronously drive each sewing head by common various drive sources. Between the source and each sewing machine head, or configure an independent drive source for each sewing machine head, so that it c...

Abstract

The aim of the present invention is to provide a threading device for embroidery machinery realized in such a way that it performs threading accurately regardless of the type of thread, for embroidery machinery, etc. capable of performing the processing for change of colored thread automatically without intervention of an operator, for example, comprises a needle support mechanism (7), disposed movably facing the hooking member (61a), for preventing deflection of the needle (10), by correcting deflection of the needle (10), when inserting the hooking member (61a) formed in the shape of a hook at the tip of the thread pull-out mechanism (61) in the needle hole (10a).

Description

【Technical field】 [0001] The present invention relates to a threading device in an embroidery sewing machine, and in particular to an embroidery machine capable of automatically exchanging colored threads (in this specification, sometimes simply referred to as "threads" or "threads"), etc. Threading device in a sewing machine. 【Background technique】 [0002] In the prior art sewing machine for embroidery, handling when changing the colored thread etc. is performed manually. [0003] However, it is necessary to stop the sewing machine when performing the process of replacing the colored thread, especially when changing the colored thread, usually when there are many heads in an embroidery sewing machine, when there are about 30 sewing heads When it is necessary to replace colored threads for each head, the sewing machine will be stopped for several hours, and there is a problem that the production efficiency and productivity of the sewing machine are low. [0004] In view...
