フダーに関する。[Detailed Description of the Invention] Industrial Application Field This invention reciprocates on a bed in front of a plurality of parallel needles in synchronization with the up and down movement of the needles, and threads the cover thread connected to the needle stitch on the right end. The cover thread spreader catches and pulls it to the left side of the left needle, and the cover thread that connects to the needle seam on the right end is caught after the sewing operation is completed, and is cut at the rear of the needle. At the same time, the cut end (free end) on the supply source side ) The present invention relates to the above-mentioned top cover thread spreader in a multi-needle sewing machine equipped with a top cover thread cutting device that holds a top cover thread.

)。Conventional technology Consists of a knife located at the rear of the needle, a presser spring that comes into elastic contact with the knife, and a hook that moves forward and backward from between the knife and the presser spring, and after the sewing work is completed, the hook advances from the rear of the needle to the front side. When retracting, it captures the top thread that extends from the right end needle stitch to the decorative thread guide, pulls it to the knife position and cuts it, and at the same time holds the free end of the top thread on the supply source side between it and the leaf spring. A device is known (Japanese Patent Laid-Open No. 61-45796).

置にはなお次のような問題があった。According to this device, since the cut end of the top thread is held in the stereotaxic stomach, the top thread extending from the device to the thread guide can be reliably captured by the hook portion of the splendid thread at the beginning of sewing. Although it can be towed in a V-shape, this device still has the following problems.

がある。In other words, conventional spreaders generally have a tongue-shaped guide section at the tip, and a hook section is formed at the stepped section at the base. However, the hook part is usually on the same plane as the circumferential part of the guide part (Japanese Patent Publication No. 54-9)
As shown in No. 112, the hook part is made to protrude horizontally inward from the above-mentioned plane, so that even if the top thread is thick or there are multiple threads, it can be securely attached to the hook part. However, since the cover is on the guide part and its thickness is relatively thin, if the free end of the top thread is held on the throat plate by the top thread cutting device as described above,
The lower part of the top thread that is pulled by the hook part and bent into a V shape, that is, the part of the top thread between the top thread cutting device and the hook part, is relatively high above the throat plate as shown in FIG. Therefore, when the spreader pulls the top thread and reaches the left swing dead center, the lower part of the top thread, which is bent in a V shape, is attached to the lower needle, especially the left needle. (See Figure 9), and the left needle descends to the outside of the V-shaped top thread, which prevents the top thread from being sewn into the left needle seam in the first stitch. be.

である。Problems to be Solved by the Invention This invention provides a multi-needle sewing machine equipped with the above-described top thread cutting device, in which the spreader pulls the top thread and bends it into a V shape when it reaches the dead center of the left swing. In order to prevent the lower part of the top thread from engaging with the needle, the left needle descends inside the V-shaped top thread to ensure that the top thread is sewn in from the first stitch. It was designed so that it would gradually decrease.

。Means for Solving the Problems The present invention is therefore such that when the sobbrefter reaches the left swing dead center, the lower part of the top thread, whose free end is held by a thread cutting device and is bent into a V shape at the hook part, descends. As shown in FIG. 1, the thread engaging part of the hook part is formed so that the lower end thereof is located below the upper surface of the guide part when the thread is pulled, so that the thread passes under the left needle. This function is to push down the lower part of the upper decorative thread.

。Embodiment Figure 3 shows an interlock stitch sewing machine, which is a typical multi-needle sewing machine equipped with a spreader, and the known needle shown in JP-A-61-45796 is diagonally behind the right needle N. The top thread cutting device 1 is equipped with a scalpel, a hook, and a temporary spring, and after the sewing work is finished, the hook advances and retreats to capture the top thread 3 between the right needle stitch and the top thread guide 2, and removes it. A device is provided to pull the right needle diagonally to the rear knife position and cut it, and to hold it between a hook and a temporary spring.

ように形成しである。The spreader 4 is adapted to swing around the needle bar in conjunction with the upper shaft, and its hook 5 is directed inward from the circumference of the guide portion 6, as shown in Fig. 1-2. The guide is protruded, and the lower part is formed to be located on the extension plane of the lower guide surface together with the tip.
したがってフック部はその上側面が斜め下向きとなって
いる。Therefore, the upper surface of the hook portion faces diagonally downward.

ときをそれぞれ示す。FIG. 4 shows the state when the spreader 4 reaches near the dead center of the left swing at the first stitch. As shown in FIG. 1, the lower part 3a of the top thread 3 which is pulled and pulled is shown in FIG. The lower part 3a is pressed down more than the conventional one as shown.
will now pass below the left needle N, without being caught by it. Therefore, the left needle N, descends into the V-shape of the top thread 3 bent at the hook portion 5 (FIG. 5), and the upper portion 3b of the top thread 3 is not lifted by the hook portion 5; Therefore, like the previous one, the upper part 3b
passes under the right needle N without getting caught, and the middle needle N
2. FIG. 6 shows when the spreader 4 moves back after reaching the left swing dead center, and FIG. 7 shows when the spreader 4 reaches the right swing dead center.

になる。Effects of the Invention As described above, the present invention provides a multi-needle sewing machine in which the free end of the top thread is held by the top thread cutting device, in which the spreader has a hook portion that catches and pulls the top thread. has the function of pushing down the lower part of the top thread leading to the top thread cutting device lower than conventional ones.
Even if the free end of the top thread is held above the throat plate by the cutting device, the lower portion of the top thread engages with the left needle when the spreader reaches near the left swing dead center. Therefore, the left needle descends into the V-shape of the top thread that is bent at the hook portion, and the top thread is sewn in securely from the last stitch.
