Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a nipple (cloth presser foot) attached to the sewing section of an embroidery machine.

[Conventional technology]

An embroidery machine that stores the embroidery pattern on a punch card, magnetic tape, or electronic storage device, and sews a thin strip of embroidery material such as cloth ribbon or resin ribbon according to the instructions, is equipped with an embroidery material separate from the stitches. There are two types: one in which a guide that guides the area directly below the nipple is fixed to a part of the embroidery machine frame, and the other in which the guide is fixed to the nipple body.

[Problem that the invention attempts to solve]

However, in any of the above types of embroidery machines, a resistor is applied to the bobbin around which the embroidery material is wound, so that the embroidery material is not loosened. For this reason, even if the embroidery material is sewn onto the embroidery base fabric, it will be flat.
It is not possible to sew in regular pleats, that is, in a frill-like or tuck-like manner, and therefore, the decorativeness obtained from the combination of the shape, pattern, and color of the embroidery material has a three-dimensional and voluminous decorativeness. The embroidery done was not as expected.

The object of this invention is to provide a nipple for an embroidery machine that can sew embroidery material in a regular frill or tuck pattern.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention adopts the following configuration of the nipple of the embroidery machine.

That is, the sewing needle has a through space in which the sewing needle moves up and down in the direction of the central axis, has a recess opening for the sewing needle at its tip, and has at least one side surface of the distal end formed in a tapered plane toward the center of the opening. The nipple of the embroidery machine is equipped with a nipple main body and a guide fixed to the outer surface of the distal end of the nipple main body to guide a narrow strip of embroidery material to a position directly below the opening. A leaf spring is supported and fixed to the nipple main body without blocking the passage of the material, and whose tip end is pressed against the tapered plane of the nipple main body, and the free end of the leaf spring is positioned near the center of the nipple body, with its free end facing the opening and exit opening. The gist of this book is the nipple of the embroidery machine, which is characterized by the fact that it is attached to the machine.

[Effect]

Since the nipple of the embroidery machine of this invention is constructed as described above, the embroidery material can be fixed by sewing to the embroidery base fabric, the nipple can be moved up and down, and the embroidery base fabric can be moved by moving the embroidery needle. The embroidery material that is pulled out is pushed in the axial direction of the nipple body by the tip of the leaf spring provided in the guide part, and the tension applied from the bobbin is broken, and the tension between the pressing part and the sewing part is This creates a condition where the embroidery material may become loose. Then, the free tip of the leaf spring located near the center of the opening surface of the opening of the needle movement port for sewing acts to form an upwardly convex slack in the embroidery material between the needles, so that the nipple main body is brought to the surface of the embroidery base fabric. When it descends to this point, the embroidery material is pressed against the embroidery base fabric and sewn with the upper convex slack formed due to the difference in the length of the embroidery material pulled out by the rise of the nipple body and the amount of needle movement. be.

〔Example〕

An embodiment of the nipple of the embroidery machine according to this invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of the nipple of the embroidery machine according to this invention, and FIG. 2 is a partially cutaway front view showing the embroidery state.

The nipple main body 10 has an upper end portion as a passive shaft portion 12 for vertical movement, and a lower end portion as an inverted conical shape 13.
It has a hollow structure with its lower end surface serving as an entry/exit opening 16 for the sewing needle 14 , and the hollow portion 18 serves as the entrance/exit opening 16 for the sewing needle 14 .
It penetrates in the direction of the central axis as a space for vertical movement. Guides 20 and 20' are erected on the outer side of the nipple main body 10 in the vicinity of the entrance/exit opening 16, with a mounting plate 21 fixed to the nipple main body serving as a substrate, with a guide path in between. The deflection of the material 24 (in this embodiment, a ribbon of a constant width) in the width direction is restrained. Leaf spring 3
0, the proximal end is fixed to a support frame 28 which is set up in the form of a gate on the mounting plate 21 so as not to impede the passage of the embroidery material, and the distal end is located between the guides 20 and 20' to hold the embroidery material 24. The nipple main body 10 is pressed in the axial direction, and the free tip 26 of the leaf spring 30 protrudes to a position near the center of the opening surface of the retractable opening 16 and does not impede the vertical movement of the sewing needle.

3A, B, and C are schematic diagrams showing the state in which the embroidery material 24 is sewn onto the embroidery base fabric 32 using the nipples described above. In FIG. 3A, the nipple main body 10 and the sewing needle 14 are both at the bottom dead center, and the sewing needle 14 pierces the embroidery material 24 and the embroidery base fabric 34 and connects it to the sewing thread (not shown). It is shown twisted and sewn. FIG. 3B shows that after the embroidery material 24 is sewn onto the embroidery base fabric 32, when the nipple body 10 and the sewing needle 14 rise, the embroidery material is guided to the guides 20, 20' as they rise. The needle is pulled out to the lower side of the nipple main body 10 for a length longer than the embroidery needle movement amount a, and an upwardly convex slack is formed at the free tip of the leaf spring 30. Figure 3C
When the nipple main body 10 is lowered in advance of the sewing needle 14, the pulled out embroidery material 24 is pressed against the opposite surface by the tip of the leaf spring 30 located between the guides 20 and 20'. The amount b pulled out to prevent it from returning upward (Figure 3 B)
This represents a state in which an upwardly convex slack is being formed by the difference in the embroidery needle movement amount a, and then the state shown in FIG. 3A occurs. By repeating this process, the embroidery material 24 is sewn onto the surface of the embroidery base fabric 32 in a frilled or tucked shape, as shown in the plan view of FIG. 4 and the side view of FIG. 5.

[Effect of idea]

According to this invention, when the nipple body is raised, the embroidery material that has been pulled out for a longer time than the embroidery needle movement is not returned upward and is sewn with the upper convex part loosened, creating a frill-like or tuck-like shape. It is possible to create embroidery with a three-dimensional volume, and it has the effect of significantly improving the decorativeness of the embroidery.
