Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thread guide hole member of a sewing machine, and more particularly to a thread guide hole member suitable for a multi-needle embroidery sewing machine.

[0002]

2. Description of the Related Art As shown in FIG. 6, a thread guide device 51 is provided above a head 61 of a multi-needle embroidery sewing machine, and a front face of a mount 52 of the thread guide device 51 corresponds to the number of needles of the head 61. A plurality of sets of thread guide tools 53 with a tension imparting mechanism, thread tension 5
4 and the yarn guide hole member 55 are arranged in the proximity of each other. In the conventional example shown in the figure, in order to correspond to the head 61 with nine needles, nine thread guide tools 53 with a tension imparting mechanism are arranged in one horizontal row, and nine thread tensions 54 are arranged in three rows and three columns. The three thread guide hole members 55 are attached below the thread tension members 54 in each row. Each thread guide hole member 55 is formed by forming three thread guide holes 57 in the L-shaped plate 56, and each thread guide hole 57 is located directly below or diagonally below each thread tension member 54. Then, the thread 60 is manually wound around the thread guide 53 with the tension imparting mechanism, and then the thread tension 5
4 is wound around, and subsequently inserted into the thread guide hole 57 of the thread guide hole member 55 from above and passed through.

[0003]

However, since the thread guide hole 57 of the thread guide hole member 55 is a simple small hole, the thread 60 is inserted into the thread guide hole 57 carefully while paying attention. There was a need. Moreover, when many members are close to each other as in the conventional example, the thread 6 is inserted into the thread guide hole 57.
When 0 was inserted, peripheral members such as the thread tension 54 immediately above were obstructive, and it was very difficult to pass through. It took a considerable amount of time to finish passing the nine threads 60 through all the thread guide holes 57.

The object of the present invention is to solve the above-mentioned problems, and even if other members are close to the periphery of the thread guide hole,
Thread can be easily and quickly passed through the thread guide hole,
Especially when it is necessary to pass the thread through many thread guide holes as in a multi-needle embroidery sewing machine, the time required can be remarkably shortened, and the thread may come off from the thread guide hole during the thread feeding. It is to provide a thread guide hole member of a sewing machine.

[0005]

In order to achieve the above object, the thread guide hole member of the sewing machine of the present invention is provided with a first thread guide piece and a second thread guide piece which are provided so as to face each other with a gap. The first yarn guide piece is provided with a first yarn guide hole and a first cut line for communicating the first yarn guide hole with the outer periphery of the first yarn guide piece. The piece has a second thread guide hole located coaxially with the first thread guide hole, and the second thread guide hole communicates with the outer periphery of the second thread guide piece at a position different from the first cut. The second cut line was formed.

[0006]

In the thread guide hole member of the sewing machine having the above-described structure, the operation of threading the thread through the first and second thread guide holes can be performed by swinging the thread and engaging the first and second cuts. You don't have to be careful while watching
It can be performed easily and quickly with the intuition of the hand.
Even if other members are close to the periphery of the thread guide hole, they hardly interfere with the above work. Therefore, particularly when the thread needs to be threaded through many thread guide holes as in a multi-needle embroidery sewing machine, the required time can be significantly shortened. Moreover, since the position of the first cut and the position of the second cut are different, there is no concern that the yarn will come off from the first and second cuts through the first and second cuts during the yarn feeding.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a thread guide hole member of a thread guide device of a multi-needle embroidery sewing machine will be described with reference to FIGS.

Similar to the conventional example, the thread guide device 1 is provided above the head 31 (details thereof are not shown) of the multi-needle embroidery sewing machine, and the head 31 is provided in front of the mount 2 of the thread guide device 1.
A plurality of sets of thread guide tools 3 with a tension imparting mechanism corresponding to the number of needles, a thread tension member 4, and a thread guide hole member 5 are arranged in close proximity to each other. In this embodiment, in order to correspond to the head 31 having nine needles, nine thread guide tools 3 with a tension imparting mechanism are arranged in one horizontal row, and nine thread tensioners 4 are arranged in three rows and three columns. Three thread guide hole members 5 are attached below the thread tension members 4 in each row. The thread guide 3 with the tension imparting mechanism and the thread tensioner 4 are known.

Each thread guide hole member 5 has a horizontally long mounting plate 7 mounted on the front surface of the mounting base 2 by a screw 6 so that the position of the thread guiding hole member 5 can be adjusted in the left-right direction, and the left end portion, the central portion and the right end portion of the mounting plate 7. Three tongue-shaped first thread guide pieces 8 integrally formed by bending from the lower edge to the front, and three attachments welded to the left end portion, the central portion and the right end portion of the front surface of the attachment plate 7. A piece 9 and three tongue-shaped second yarn guide pieces 10 that are integrally formed by bending forward from the lower edge of the attachment piece 9 are provided. The first yarn guide piece 8 and the second yarn guide piece 10 at each position face each other with a gap of about 1 mm to form a pair.

The first thread guide piece 8 has a first thread guide hole 11 therein.
And a first cut 12 which connects the first yarn guide hole 11 to the outer periphery of the first yarn guide piece 8 from the left side in FIG. The second yarn guide piece 10 has a second yarn guide hole 13 located coaxially with the first yarn guide hole 11.
And a second cut line 14 for communicating the second yarn guide hole 13 from the right side in FIG. 1 to the outer periphery of the second yarn guide piece 10. The first and second yarn guide holes 11 and 13 are located directly below or obliquely below the yarn tension 4 and have a diameter of about 2.5 mm. The width of the first and second cuts 12 and 14 is about 1.6 mm.

Then, the thread 30 is manually wound around the thread guide 3 with the tension imparting mechanism, then wound around the thread tensioner 4, and hooked on the thread take-up spring 15 of the thread tensioner 4. The thread 30 passing through the thread take-up spring 15 is swung in the right lateral direction, is hooked from the right side to the second cut 14 of the second thread guide piece 10, and is passed through the second thread guide hole 13. The yarn 30 passing through the second yarn guide hole 13 is shaken in the left lateral direction, is hooked from the left side to the first cut 12 of the first yarn guide piece 8, and is passed through the first yarn guide hole 11.

Thus, the first and second yarn guide holes 11,
The operation of threading the thread 30 through the thread 13 can be performed by swinging the thread 30 in the lateral direction and hooking the thread 30 on the first and second cuts 12 and 14. Therefore, it is not necessary to perform the operation carefully while paying attention as in the conventional case. It can be done easily and quickly by intuition. Further, even if many members are close to each other on the front surface of the mounting base 2 (especially, the first and second yarn guide holes 11 and 1).
(Though thread tension 4 is present directly above 3), these will rarely interfere with the above work. Therefore, it is possible to remarkably reduce the time required to finish passing the nine yarns 30 through all the first and second yarn guide holes 11 and 13.

Further, since the position of the first cut 12 and the position of the second cut 14 are different, the yarn 30 moves from the first and second cuts 12, 14 to the first and second cuts 12, 14.
There is no worry of coming off to the side after going through.

The present invention is not limited to the configuration of the above-described embodiment, but may be modified and embodied without departing from the spirit of the invention, for example, as follows. (1) As shown in FIG. 4, the first cut 12 is provided on the front side of the first yarn guide hole 11, and as shown in FIG. 5, the second cut 14 is provided on the front side of the second yarn guide hole 13. Properly changing the position of the first cut 12 or the second cut 14, such as by providing. (2) The size and shape of each part of the yarn guide hole member 5 such as increasing or decreasing the gap between the first and second yarn guide pieces 8 and 10 and bending the first cut 12 or the second cut 14 on the way. Change the dimensions appropriately. (3) In addition to the multi-needle embroidery sewing machine, be embodied as a thread guide hole member for various sewing machines.

[0015]

Since the thread guide hole member of the sewing machine of the present invention is constructed as described above, even if another member is close to the periphery of the thread guide hole, the thread guide hole member is provided with a thread. It can be threaded easily and quickly, and especially when the thread must be threaded through many thread guide holes as in a multi-needle embroidery machine, the time required can be significantly shortened and the thread can be threaded. It has an excellent effect that there is no fear of coming off from the thread guide hole during feeding.
