Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] First, the outline of the multi-head sewing machine of the present invention will be briefly described. figure 1 It is a front appearance view showing an embodiment of the multi-head sewing machine of the present invention. This embodiment shows a multi-head sewing machine having a plurality (eight in the figure) of sewing machine heads H capable of sewing a string-like member. in addition figure 1 Among them, the front side corresponds to the front of the multi-head sewing machine at the actual position where the operator performs sewing work or the like.

[0025] figure 1 In the shown multi-head sewing machine, an upper frame 2 is disposed above an elongated sewing machine table 1 extending in the horizontal direction (X direction in the figure), and on the front surface of the upper frame 2, along the upper machine Sewing machine heads H ar...

Abstract

A sewing machine, wherein holding members (46) and (48) for holding a thread hung on a needle thread take-up (17) to be swung at a position on the downstream side of the needle thread take-up and on the upstream side of the sewing needle fitted to a needle bar are provided in a sewing machine head. During the rest of operation of the sewing machine head, the movement of the thread on the downstream side of the needle thread take-up is stopped irrespective of whether the needle thread take-up is swung or not since the thread (T) is held by the holding members. The tip of the thread hung on the needle thread take-up is passed through the pin hole of the sewing needle fitted to the needle bar. When the needle thread take-up is swung, the hung thread is tensed or loosened according to the swing movement. However, since the thread is held by the holding members on the downstream side of the needle thread take-up in the sewing machine head in the rest of operation, the thread passed through the pin hole is not extracted from the pin hole even if the needle thread take-up is swung. By such a simple structure, the thread can be prevented from being extracted from the pin hole.

Description

technical field [0001] The present invention relates to a sewing machine with an improved sewing thread holding structure on the head of the sewing machine at rest. sewing machine head on a multi-head sewing machine. In particular, when a multi-head sewing machine is used, and when only a part of the plurality of sewing machine heads is in operation and the work of the remaining sewing machine heads is at rest, a simple structure can be used to prevent sutures from coming out of the sewing machine heads at rest. A multi-head sewing machine in which the needle holes of each sewing needle come out. Background technique [0002] Conventionally, there is known a multi-head sewing machine having a plurality of sewing machine heads, the sewing machine head has: a needle bar that is driven up and down and contains sewing needles at the lower end; thread take-up lever; assembled on the same axis as the needle bar, a rotating body that can freely rot...
