Therefore, there are drawbacks in that the sewing operation and the monitoring thereof are sparse, and complicated labor is required. Also, when you want to check the remaining amount of the wound yarn during the embroidery operation, or to check the condition of the yarn guidance and its troubles, the work side is blocked by the needle head, the mounting frame, the yarn adjustment device, etc. There are drawbacks such as difficulty in visual recognition and difficulty in immediately correcting and coping with yarn modulation and feeding trouble. They also had to shut down the embroidery machine to take care of these problems and needed assistance. When installing such an embroidery machine indoors, it is necessary to provide a passage at the rear of the machine body for setting and maintaining the winding thread and a sufficient space for the operator to work with a margin. Because there is
There are problems such as occupying a large installation space.

The handle 33 is provided so that the height of the handle 33 is higher than the height of the winding thread S <b> 1 mounted on the thread stand 30 in a standing shape. The front and rear ends of the thread stand frame 32 are bent to the back side, and on both sides of the lower surface thereof, the installation portion 7 of the support arm 76 described later is installed.
The engaging portion 35 is formed so as to be recessed so as to engage with 7, and the engaging portion 35 is provided with the handle 33 when the thread stand 3 is piled up in a shelf shape as shown in FIG. 6 (A). Is configured to be positioned so that the head of the can be engaged. Therefore, by preparing more than the number of thread stand bases 3 to be set on the thread support device 3A, the winding thread S required for the next step can be mounted on the thread stand bases 3A.
There is an advantage that the yarn replenishing work can be efficiently performed by performing the setting of No. 1 beforehand.

通するとよい。Further, as shown in FIG. 4, the thread guide 6 is formed by continuously forming a large number of guide pieces 6G formed in the shape of smooth projections on the inner surface of the tubular tube. The guide pieces 6G form the sewing needle 20 of the needle head 2. The thread S stretched between the thread stand 3 and the thread stand 3 is guided so as to be in point contact with the thread stand 3 so that it can be smoothly guided and guided in a state where the feeding resistance is as small as possible. The initial threading to the thread guide 6 is performed by the winding thread S1.
In a state in which the unthreaded yarn S is inserted into the inlet 6p of the yarn guide 6, it may be inserted through the yarn passing tool 6W toward the outlet 6t.

The thread can be easily and accurately threaded through the guide 6. The threading means may be performed by using a threading tool such as a wire. In this case, the thread guide 6 can be point-contacted without necessarily forming the thread guide 6 in a bellows-like cylindrical tube. A configuration may be such that a plurality of rings that guide the user are installed.

に行うことができる。On the side of the thread stand 3 of the thread guide 6, that is, on the side of the entrance 6p, a thread holding means 6H for removably securing the end of the thread S inserted through the sewing needle 20 of the needle head 2. When the sewing needle 20 is in a resting state, the end of the thread S inserted through the sewing needle 20 is detachably fastened at the entrance 6p side while maintaining the posture of being inserted through the thread guide 6. I can do it. Thus, when the sewing needle 20 is to be used again, the thread S inserted through the sewing needle 20 is removed from the thread holding means 6H, and the thread S is used as a thread, and the next thread S end By performing the pulling operation so that the thread guide 6 and the needle hole of the sewing needle 20 are inserted in a state in which the thread is tied, the initial threading as described above is not required and can be easily performed.

ができる等の特徴がある。As described above, in the feeding device 5, the lifting mechanism 5a is mounted via the lifting frames 7 and 7, and the lifting mechanism 5a is extended from the embroidery machine 1 toward the upper front side. With the suspension structure, it is possible to retrofit the embroidery machine to a conventional embroidery machine easily and at a low cost without requiring a large amount of modification. The feeding device 5 does not necessarily have to be integrally installed on the embroidery machine 1 itself, but the lifting mechanism 5a or the hanging member 73 may be different from the embroidery machine 1 such as the ceiling of a building as shown by the dotted line in FIG. It may be configured by mounting via another mounting frame body 1T. In this case, it is possible to omit members such as stanchions of the elevating mechanism, and in the same manner as described above, for conventional embroidery machines. However, it has a feature that it can be retrofitted more easily, and that the transmission of vibration on the embroidery machine 1 side to the yarn feeding device 5 can be suppressed.
