Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides an embroidery machine that allows the fine thread threaded through the embroidery needle to always penetrate the very thick thread when forming an embroidery of an arbitrary pattern made of very thick thread. The present invention relates to an embroidery device for thread sewing and an embroidery thread guiding device used therein.

(Prior Art) An example of a temporary embroidery device that can form embroideries of arbitrary patterns using extra-thick threads is disclosed in Japanese Patent Publication No. 52-39328. As shown in FIG. 8, the embroidery device uses an embroidery needle e through which a fine thread d is passed through a maximum system C that is unwound from a bobbin b that is placed above an embroidery forming part a at a considerable distance. The embroidery needle e is inserted loosely directly into the guide hole g to be passed through.
was configured to pass through the central portion of the guide hole g.

(Problems to be Solved by the Invention) In the case of such a device, when the processed sheet material descends, as shown in FIG. The embroidery needle e with the thin thread d passing through it will surely penetrate the extra-thick thread C, and therefore the extra-thick thread C
is sewn onto the processed sheet-like material using thin thread d. However, if the processed sheet-like object rises or moves to the right or left, the In this case, the state is symmetrical to that in FIG. Since the distance between the embroidery needle e and the bobbin b is large, it is difficult to stably fix the bent part J of the thick thread in the guide hole g, and the embroidery needle e passes through the center of the guide hole g. It often happens that the thread passes through the opening k without penetrating the very thick thread C (hereinafter referred to as skipping).

In this way, when using conventional equipment, due to skipping,
This resulted in a large number of extra-thick thread parts coming loose from the processed sheet material, making it virtually impossible to mass-produce high-quality embroidery products using extra-thick thread.

SUMMARY OF THE INVENTION An object of the present invention is to provide an embroidery device for sewing extra-thick threads and an embroidery thread guiding tool used therein, which solves the problems of the prior art and makes it possible to mass-produce luxurious embroidered products.

(Means for Solving the Problems) In order to solve the above problems, the present invention employs the following means. That is, the embroidery device (hereinafter referred to as the device) 1 for sewing extra-thick thread according to the present invention is provided with a presser 3 so as to face the processed sheet material 2 which is stretched over a holding frame and is movable. , repeatedly approaches and moves away from the processed sheet-like object 2, and presses the processed sheet-like object surface 21 by approaching the processed sheet-like object 2; A guide hole 10 is provided to allow the thread 9 to pass through the thread 9, and the very thick thread 9 to be unwound from a bobbin (not shown) is guided in close proximity to the guide hole 10 (preferably at a distance of about 2 to 3 cm). A guide portion 12 is provided (a preferred embodiment of the guide portion 12 is a through hole), and the guide hole 10 and the guide portion 12 constitute an embroidery thread guide portion 13; and the embroidery needle 7
It is characterized in that it is inserted through a portion of the guide hole 10 closer to the guide portion 12.

Here, the thin thread 6 refers to a thin thread that is commonly used to form embroidery patterns, and the extra-thick thread refers to wool or string with a diameter larger than the thin thread (for example, about 3 to 5 mm in diameter). It also refers to a narrow tape-like object.

The embroidery thread guiding section 13 may be formed integrally with the presser 3, but the present invention is directed to the presser 3 in which the upper portion 15 has a comb-like shape and has the following configuration. It is preferable to use an embroidery thread guiding tool 5. That is, the embroidery thread guiding device 5 has pressing pieces 16 arranged in parallel that form the comb-like upper portion 15 of the presser 3.
A rising piece 25 extending upward is connected to the fixed piece 23 that is fixed to a required object, and an embroidery needle 7 with a fine thread 6 passed through it is attached to the upper end of the rising piece 25 together with a very thick thread 9. A guide hole 10 for passing through is provided between adjacent pressing pieces 16, 16, and a through hole is provided in the rising piece 25 for guiding the thick yarn 9 on an inclined line extending diagonally downward of the guide hole 10. The shaped guide portion 12 is provided such that its hole axis coincides with the direction of the inclined line.

Note that the rising piece 25 of the embroidery thread guide 5 is such that when the presser 3 presses the surface 21 of the processed sheet-like object, the peripheral portion 27 of the guide hole 10 moves the guide hole insertion portion 29 of the extra-thick thread into the processed sheet-like object. It is preferable to bend it toward the processed sheet-like object surface 21 so as to press it against the surface 21.

(Function) However, the very thick thread 9 unwound from the bobbin is guided to the guide section 12.
If the embroidery needle 7 with the thin thread 6 passed through the guide hole 10 is inserted into the guide hole 10 in this state, the embroidery needle 7 will be able to pick up the extremely thick thread no matter which direction the processed sheet material 2 moves. 9 will definitely be penetrated, and therefore,
The thick thread 9 is reliably sewn to the processed sheet-like material 2 by the thin thread 6.

This will be explained below by taking as an example a case where the guide portion 12 as the through hole 12a is provided diagonally below the guide hole 10.

4 to 7 are explanatory diagrams illustrating the insertion state of the thick thread 9 in the guide hole 10 and the positional relationship of the embroidery needle 7 with respect to the thick thread insertion portion 29.

FIG. 3 shows a case where the processed sheet material 2 is in the ascending GFI, and the extra-thick insertion portion 29 is inserted into the guide hole IO.
Covers the entire area. Therefore, it goes without saying that the embroidery needle 7 penetrates the very thick thread 9.

FIG. 5 shows a case where the processed sheet-like object is in the descending state F2, and the extra-thick insertion portion 29 is bent in a V-shape at the lower edge portion 31 of the guide hole 10. As shown in FIG. Since the extra-thick yarn 9 inserted through the guide hole 10 is guided and pulled out by the guide portion 12 provided close to the guide hole 10, a considerable amount of thread is passed through the guide hole g as shown in FIG. This is completely different from the case in the conventional device in which the extra-thick thread C unwound from the bobbin b arranged at a distance is directly inserted into the guide hole g.
The lower edge portion 3 of the guide hole 10 in the bent state
1 and is stably fixed in position. On the other hand, the embroidery needle 7 that is inserted through the guide hole 10 is positioned so as to be inserted through a portion of the guide hole 10 that is closer to the guide portion 12 . Therefore, the extremely thick insertion portion 29, which is stably fixed in position, can be reliably penetrated by the embroidery needle 7.

FIG. 6 shows a case where the processed sheet-like material 2 moves rightward F3, and the extra-thick insertion portion 29 is bent at the lower part 32 of the right edge of the guide hole 10, and the bent state is shown in FIG. It is stably fixed in position. Therefore, the embroidery needle 7 inserted into the guide hole 10 near the guide portion 12 reliably passes through the extra-thick insertion portion 29.

FIG. 7 shows a case where the processed sheet material 2 moves to the left F4, and the extra-thick insertion portion 29 is inserted into the guide hole 1.
It is bent in a figure 7 shape at the lower part 33 of the left side edge of the 0, and is stably fixed in position in the bent state. Therefore, the embroidery needle 7 inserted into the guide hole 10 near the guide portion 12 reliably passes through the maximum system insertion portion 29.

When the presser 3 presses the processed sheet-like object surface 21, as shown in FIG.
When 7 presses the guide hole insertion part 29 of the extra-thick thread 9 against the processed sheet-like object surface 21, in combination with the stable position fixing of the extra-large system insertion part 29 by the guide part 12, the extra-large thread insertion part 29 is pressed against the embroidery needle. This is preferable because the position can be more stably fixed when the hole is penetrated by the hole 7.

(Example) Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 to 3, an apparatus 1 according to the present invention fixes an embroidery thread guiding tool 5 to a presser 3 facing a needle 1-like object 2, such as cloth, which is stretched over a holding frame and is movable. This creates a guide hole 10 through which the embroidery needle 7 with the thin thread 6 passed together with the extra-thick thread 9, and a guide section 1 that guides the extra-thick thread 9 unwound from the bobbin (not shown).
The embroidery thread guide section 13 is formed by forming an embroidery thread guide section 13 consisting of 2.

The presser 3 has an upper portion 15 formed into a comb-teeth shape in which pressing pieces 16 extending in the vertical direction are arranged in parallel at a predetermined interval, and a movable frame 1 that moves forward and backward with respect to the processed sheet material 2.
Its lower part 19 is fixed to 7. However, as the movable frame 17 advances and retreats, the presser 3 repeatedly approaches and moves away from the processed sheet-like material 2, and as a result of this approach, the back side is exposed to the needle play 1-20 as shown in FIG.
The processed sheet-like material 2 received by is pressed with its front processed sheet-like material surface 21.

As shown in FIGS. 1 and 2, the embroidery needle 7 repeatedly approaches and moves away from the processed sheet-like object 2, and is placed on the needle rest 22, which is provided opposite the plane sensor 3, to the required adjacent pressing pieces. 16.It is fixed at a position between 16 and 16. The timing of the forward and backward movements of the presser 3 and the forward and backward movements of the embroidery needle 7 is exactly the same as in the conventional device.

The embroidery thread guiding tool 5 is attached at a portion near one end 24a of the fixed piece 23, which is attached across the adjacent pressing pieces 16 and 16.
A rising piece 25 is provided that extends upward and has an upper end bulged toward the other end 24b of the fixed piece 23. The upper bulging portion 26 of the rising piece 25 is provided with a guide hole 10 through which the embroidery needle 7 through which the thin thread 6 is threaded passes together with the thick thread 9. In addition, the guide hole 1 is provided in the rising piece 25.
A guide portion 12 serving as a through hole for guiding the thick yarn 9 is provided on an inclined line extending approximately 45 degrees downward from zero so that the axis of the hole coincides with the direction of the inclined line. The guide portion 12 is preferably provided at a distance of about 2 to 3 cm from the guide hole 10. In this embodiment, when the presser 3 presses the processed sheet-like object surface 21, the peripheral portion 27 of the guide hole 10 presses the guide-hole insertion part 29 of the extra-thick yarn 9 against the processed sheet-like object surface 21. Yo,
The rising piece 25 is bent toward the processed sheet-like object surface 21.

The embroidery thread guiding tool 5 having such a configuration has, for example, a first
As shown in Figure 3, the adjacent pressing pieces 16 and 16 are sandwiched between the fixing piece 23 and the clamping piece 30, and are fixed to the presser 3 by tightening bolts on both sides of the fixing piece 23. At this time, the embroidery thread guide 5 is positioned so that the embroidery needle 7 is inserted through a portion slightly below the center of the guide hole 10 (a portion closer to the guide portion).

The guide hole 10 and the guide portion 12 of the embroidery thread guide 5 installed in this manner allow the embroidery thread guide portion 13 to be
The thick yarn 9 is unwound from a bobbin disposed at the front edge of the machine base, and is passed through a guide portion 12 serving as a through hole, and then inserted into a guide hole 10.

The action of the device 1 having such a configuration is the above-mentioned 1 action.
However, in this embodiment, the guide portion 12 as a through hole is approximately 45 mm wide of the guide hole 10.
Since it is provided so that it lies on an inclined line extending in a downward direction, and its hole axis coincides with the inclined direction, the guide part 12 and The bending angle at the guide portion of the maximum system 9 guided to the guide hole 10 can be made as large as possible, and therefore the frictional resistance of the extremely thick yarn 9 that is received when the guide F section is inserted can be minimized, and the extremely thick yarn 9 can be moved more smoothly. It leads to scales. Note that when it is not necessary to sew the extra-thick thread 9 onto the processed sheet-like object 2, in other words, when embroidery is to be performed using only the thin thread, the extra-large thread 9 is removed from the guide hole 10.

In the present invention, it is preferable that the guide portion 12 be disposed diagonally downward (lower right or lower left) in order to configure the device of the present invention using an existing device. The arrangement site is not limited thereto, and can be set at any direction centering on the guide hole 10 as long as there is no problem with the configuration of the device. Also, setting the position of the embroidery needle 7 so as to insert it through the portion of the guide hole 10 near the guide portion 12 means that when the extra-thick thread 9 is folded back at a small angle in the guide hole 10 (for example, as shown in FIG. In the case shown in Fig. 7), the embroidery needle 7 is inserted into the extra-thick thread insertion part 2.
This means that the setting is made so that the hole passes through the hole 9 reliably. For example, if the guide part 12 is provided diagonally below the guide hole 10, the embroidery needle 7 is positioned so as to be slightly offset diagonally downward from the center of the guide hole 10, or It is positioned slightly below the center of the guide hole 10.

(Effects of the Invention) The device of the present invention is configured to include an embroidery thread guiding section consisting of a guide hole and a guide section adjacent to the guide hole, and the embroidery needle is inserted through a portion of the guide hole near the guide section. Therefore, insert the thick thread unwound from the bobbin through the guide hole from the guide part, and in this state,
When you insert an embroidery needle with fine thread through the guide hole,
No matter which direction the processed sheet-like object such as cloth moves, the embroidery needle will reliably penetrate the extra-thick thread, and therefore the extra-thick thread will be reliably sewn onto the processed sheet-like object with the silk thread.

For this reason, for example, after forming a desired embroidery on a processed sheet using only silk thread without passing extra-thick thread through the guide hole, the processed sheet may be left stretched over the holding frame. By inserting extra-thick thread through the guide hole and subsequently forming embroidery with a desired pattern using extra-thick thread, luxurious embroidered products with excellent decorative effects can be mass-produced. Moreover, as mentioned above, silk thread embroidery and extra-thick thread embroidery can be performed consecutively depending only on whether or not to insert extra-thick thread into the guide hole. Since there is no need for pattern matching, which requires skill, such luxurious embroidery products can be manufactured at low cost.

In the apparatus of the present invention, when the presser presses the surface of the processed sheet-like object, the peripheral edge of the guide hole presses the guide hole insertion part of the extra-large system against the surface of the processed sheet-like object, so that the extra-thick thread can be inserted. When the part is penetrated by an embroidery needle, the part is stably fixed in position and becomes a scale.

When the embroidery thread guiding section in the device of the present invention is constituted by an embroidery thread guiding device consisting of a galloid hole and a guide section, the embroidery thread guiding device can be fixed to the pressing piece of the presser of the existing device, so that the embroidery thread guiding section can be fixed to the pressing piece of the presser of the existing device. The scales constitute the device of the invention. As described above, it can be said that the ability to construct the apparatus of the present invention without requiring any special modification of the conventional apparatus is extremely useful from both a practical and economical point of view.
