Abstract

PURPOSE:To enable wind thread shank sewing to be performed without generating cloth wrinkles on the peripheries of stitch forming sections by retaining spaces between buttons and a cloth piece in the horizontally retained state of the buttons, to be spaces larger than previously set finish spaces by specified quantities, and by resetting the spaces between the buttons and cloth piece to be the finish spaces, in the vertically retained state of the buttons. CONSTITUTION:On stitch thread Sa for connecting buttons B and a cloth W to each other with, specified tensile forces which are previously set according to the thread conditions and the like of a sewing machine are generated, and stitch thread Sa, Sb are set in stretched states. When stitch working is completed, then the cylinder rod 41a of a cylinder 41 is set in a concealed state, and a push-up lever 40 is moved down and the pressure application of a slide member 23 is released. Then, the slide member 23 is moved down to an initial position due to the energizing force of a spring, and so button retaining members 31A, 31B are also moved down, and spaces between the buttons B and the cloth W are reset to original finish spaces (t). As a result, the stitch thread Sa, Sb are loosened to be set in states that the tensile forces are not generated on them. Then, on the cloth, wrinkles due to the stitch thread are not generated, and excellent stitch quality can be obtained.

This mechanism includes a tongue l that holds the button sewing part of the cloth W in a bent state as shown in FIG. A plate 2 and a button holding member 3 capable of holding the button B horizontally or vertically are provided. When the button B is sewn onto the cloth W, the button holding member 3 first attaches the button to the tongue 1.
and the button B is positioned horizontally above the cloth W held on the support plate 2 (FIG. 9(a),
(see (b)). Then, when the sewing machine is driven, the tongue l, the support plate 2, and the button holding member 3 move horizontally in synchronization with the raising and lowering movement of the sewing needles, and the sewing needles N are alternately dropped into the button sewing holes Ba. to form a single thread chain stitch, and sew button B.

There is also the effect that it is possible to prevent the occurrence of an unsightly appearance caused by the Sba being pushed wide. That is, by applying the plate-wound stitch, the seam threads Sa and Sb are squeezed inward by the plate-wound thread Sc and are in a thin and converged state, so that the button pole becomes thick (no longer pushed apart).

[Problem to be solved by the invention] As mentioned above, it is desirable to narrow the seam threads Sa and Sb as thinly as possible, but in conventional sewing machines, in the plate wrapping stitch, the stitches performed before The tension applied by the sewing operation is directly generated in the stitching threads Sa and Sb, and as shown in Fig. 10(a), the stitching threads Sa and Sb are in a stretched state, so the sewing threads Sa and Sb are not squeezed inward much. However, there was also the problem that the plate-wrapped portion could not be formed sufficiently thin.

For this reason, it is conceivable to increase the thread tension of the plate-wound thread Sc and forcibly squeeze the seam threads Sa and Sb inward, but in this case, as shown in Fig. 10(b), the seam threads The fabric W is pulled upward together with Sa and Sb, causing the inconvenience that wrinkles Wl are generated around the seam forming part of the fabric W.
As a result, the quality of the sewing material was significantly impaired.

[Means for Solving the Problems] This invention performs sewing operation with the button held horizontally by a button holding member, and then holds the button vertically to create a seam that connects the fabric and the button. In a button-sewing machine that performs board-wrap stitching on thread, a spacing adjustment mechanism is provided for relatively adjusting the spacing between a button-clamping member that clamps a button and a cloth-holding member that holds a cloth, and the spacing adjustment mechanism is provided. A control means for controlling the mechanism is provided, and the control means maintains the distance between the button and the cloth at a distance larger than a preset finishing distance by a predetermined amount when the button is held horizontally, and when the button is held vertically. , the distance between the button and the cloth is returned to the finished distance.

[Function] The button holding member in this invention holds the button at an interval larger than the preset finishing interval during the sewing operation between the button and the cloth, and when the sewing operation is completed, the button is held vertically. In the maintained state, that is, the distance between the button and the cloth is returned to the finishing distance prior to the board-wrapping operation. As a result, there is room for the seam thread, so it is possible to converge the sewing thread thinly by the board-wrapping operation, and even if the seam thread is converged inward, excessive tension will not be generated in the seam thread. The fabric will no longer be pulled along with the seams. Therefore, wrinkles do not occur in the cloth.

Since slack is formed in sb due to the previous operation,
Even when the stitching threads Sa and Sb are squeezed inward by the root wrapping thread Sc, almost no tension is generated in the stitching threads Sa and Sb, and as shown in FIG. 7(c), the root wrapping thread Sc This results in a narrow convergence state. Therefore, even if the knead is inserted into a buttonhole or the like, the buttonhole will not be unsightly spread out, and the buttonhole will be properly locked into the buttonhole.

In addition, since neck-wrapping stitching can be performed without creating excessive tension in the seam threads Sa and Sb, it is possible to
This eliminates the inconvenience of wrinkles caused by being pulled upward by the seam thread, and excellent stitching quality can be obtained. Thereafter, when the neck wrapping sewing operation is completed, a thread cutting mechanism (not shown) operates to cut the thread connected to the sewing needle N, and the cylinder rod 18a of the cylinder 18 is brought into a protruding state, and the button clamping members 31A and 31B are The sewing machine returns to the initial position and the series of sewing operations ends (step 7.

[Effects of the invention] As explained above, the button sewing machine according to this invention is equipped with an adjustment mechanism for adjusting the distance between the button and the cloth, and when sewing buttons, the button sewing machine can adjust the distance between the button and the cloth to be larger than the finishing distance. The sewing machine is held at the same position and returns to the finishing interval during the neck wrapping sewing operation, and neck wrapping sewing is performed with a margin in the seam thread, which prevents excessive thread tension from being generated in the seam thread. You can perform neck-wrapping stitches without having to. For this reason, the sewing thread can be converged into a thin layer using the neck wrapping thread, which prevents the buttonhole from being pushed wide when the button is attached, and also prevents wrinkles from forming on the fabric due to the sewing thread. , you can expect excellent stitching quality.
