Abstract

PURPOSE: To prevent the generation of a skip stitch by providing a sewing machine with a device for moving the thread end of needle thread hung from a needle between a cloth presser and a needle plate from a rear part to a front side, installing a thread end holder in front of a needle passing hole at the lower surface of the cloth presser and thereby preventing the slackening of the thread at a sewing start end. CONSTITUTION: An air ejecting pipe 9 as a thread end moving device whose one end is connected through a valve 8 to a high pressure air source 7 is disposed in the rear part and on the slightly left side of a sewing machine needle 1 and an ejecting port 10 formed on the other end of the air ejecting pipe 9 is opened towards the slightly right side in front of the sewing machine at the upper surface of the needle plate 2. In the meantime, an intake pipe 13 as the thread end holder whose air sucking port 12 is opened in front of the needle passing hole 11 at the lower surface of the cloth presser 6 is attached and the intake pipe 13 is connected to an air evacuating device 16 through a flexible connecting pipe 14 and the valve. Then, the thread end of the needle thread cut and hung from the needle 1 when sewing is ended is sent from the needle passing hole 11 of the cloth presser 6 to the front side by ejected air from the ejecting port 10 and held by air sucking force at the sucking port 12.

Various types of yarn end holding devices such as No. 92 and Jitsukaihei 2-4577 are used. However, since these thread end holding devices hold the thread ends above and to the side of the presser foot of the sewing machine, the thread tension increases as the needle drops when sewing is started, and the thread end is held. If the release timing does not match, there is a problem that abnormal tension is applied to the needle thread to cause puckering on the cloth, or the thread is loosened and skipped.

きる。In this sewing machine, a high-pressure air source 7 is connected through a valve 8 at one end, and a fumarole tube 9 as a yarn end moving device is connected.
Is provided on the rear side of the sewing machine needle 1 (on the left side in the figure) and slightly on the left side, and the discharge port 10 provided on the other end is opened toward the front side (on the right side in the figure) of the sewing machine on the upper surface of the needle plate 2 toward the right side. I am letting you. On the other hand, the needle passing hole 11 on the lower surface of the presser foot 6
An intake pipe 13 serving as a yarn end holding device having an air suction port 12 opened to the front is provided, and the intake pipe 13 is connected to an air pressure reducing device 16 via a flexible connecting pipe 14 and a valve (not shown). are doing. The valves 8 and the like can be manually operated, but are controlled by a drive control mechanism of a sewing machine (not shown). Further, the drive control mechanism of this sewing machine can control the valve in association with the operations of the needle thread cutting device and the cloth presser lifting device.

保持される。In the apparatus of this embodiment, after sewing the cloth, the needle thread NT connected to the rear end of the cloth is cut, the cloth presser 6 is lifted to remove the cloth, and then the fumarole pipe provided behind the sewing machine needle 1. When air is ejected from the discharge port 10 of 9 toward the front arrow A direction on the upper surface of the needle plate 2, the thread cutting end TE which is continuous with the lower part of the needle 1 is arranged along the lower surface of the presser foot 6 in the vicinity of the air suction port 12. Be sprayed on. The yarn end TE is sucked and held in the intake pipe 13 by the suction action of the air pressure reducing device 16 connected to the air suction port 12 via the connecting pipe 14 and the valve 15.

ることがない。Next, when the cloth W to be sewn next is supplied onto the needle plate 2 and the cloth presser 6 is lowered onto the needle plate, the needle thread whose thread end TE is held in the intake pipe is The part TM closer to the needle is sandwiched between the upper surface of the cloth and the lower surface 6a of the cloth presser between the needle hole 11 of the cloth presser and the air suction port 12. In this way, the state in which the thread end is held between the lower surface of the presser foot and the cloth at the start of sewing is the same as the state of the thread during normal sewing, so that thread slack or pulling occurs. Never.

高めることができる。As described above, according to the present invention, in the sewing operation by the sewing machine, the thread end of the needle thread that is cut off at the end of sewing and hangs down from the needle is also moved from the needle passage hole of the presser foot to the front side by the moving device. The sewing machine holds the sewing machine along the lower surface of the presser foot by the holding device, and when the sewing is started next time, the thread end of the needle thread is sandwiched between the upper surface of the cloth and the lower surface of the presser foot, and the sewing machine is stopped during sewing. When the sewing machine is started, the needle thread forms a stable needle thread loop as the cloth advances, so that the occurrence of skipped stitches that tends to occur at the start of sewing can be prevented. Further, the work efficiency can be improved by controlling the yarn end moving device and the holding device in association with the sewing machine drive device, the thread trimming device, the cloth presser lifting device, and the like.
