Explanation of the invention (3) The drive mechanism acts on the line regulator, so that it is applied from the line regulator The tension of the thread is changed; and the control mechanism is to change and control the tension of the thread hung on the aforementioned thread regulator by controlling the power output to the driving mechanism. As a result, a series of reinforcing seams and side seams are formed, so the operator does not need to adjust the thread tension, and can automatically change to form a lock seam and an embroidery seam. If the zigzag stitch is formed by a high-density zigzag stitch having a narrower width than the side stitches, the fabric can be further strengthened. Furthermore, in the buttonhole lockstitch sewing machine of the present invention, during the formation of the zigzag seam and the side seam, a zigzag seam with a lower density than the linear seam or side seam is formed on the zigzag seam. Thereby, a button hole and a seam with soft touch can be obtained while reinforcing the fabric. In addition, according to the present invention, a method for forming a seam of a buttonhole lockstitch machine is provided, wherein the buttonhole lockstitch machine includes a seam forming mechanism formed by a pair of formed along the openings in the object to be sewn. Side seams at both ends of the button hole, and at least one side of the button hole, so as to form a button hole lock stitch suture continuously with the seam on both sides of the button hole; Before the formation of the seam suture, the overlapping seam formed by the zigzag seam narrower than the side seam or the reinforcing seam formed by the straight seam is repeated multiple times, and is formed on the continuous side seam of the side seam and the two side seams. The seam is formed so that the needles do not fall at the same point. With this, it is possible to solve the problems such as cutting of raw silk and poor sewing caused by the same point where the needle falls, and the quality of the material to be sewn can be greatly improved.

Description of the invention (17) Because the solenoid 60 can change the adjustment of the disk clamps 66 and 67 with almost no change in stroke Force, so it can be set almost instantaneously in time. Next, control the feed, baseline, and amplitude pulse motors 20, 40, and 41 to move the seam start positions (P1), (S-11) on the left. Then “reinforcement stitching is started from the seam starting point P1, with the set stitching pitch and alternately falling on the right side edge R1 and the left side edge L1 determined by the set stitch width. The zigzag seam on the upper side forms the reinforcement seam on the left side (s-12) from the bottom of Figure 14. The pitch of this reinforcing seam is set to be much finer than the side seam spacing of the Nuozhi hole lockstitch suture because of the non-fulfillment value. By setting the cutting length a from the panel 110, the length of the knife to the first seam gap g, and the length of the knife to the second seam gap h, the side seam length is obtained from V = a + g + h; The length is set to the same length; the length of the reinforcement seam (Fig. 8, item ν〇 · 20) set on the panel and the length of the reinforcement seam are calculated in the aforementioned sewing data processing (S-2) during the period.

Description of the invention (is) 'Same as above, with the set stitch pitch alternately falling on the right side edge R2 and above the left side edge, and then sew down from above the 14th figure, borrow It calculates the needle position signal (s-17) of the lockstitch machine. If it is the same as the needle value (Na), it stops at the needle up position. Since this reinforcing seam is formed by the zigzag seam with a small seam pitch as described above, the fibers are restricted by the sewing thread, so that the fibers in the vertical and horizontal directions are not loosened or unraveled. Although it is best to set the pitch of this seam to be very fine, it is thicker than the fabric and has no effect on the effect. In addition, the reinforcement seam is formed when the side seam of the buttonhole lockstitch suture is formed, and has a bulging effect along the buttonhole near the center portion thereof, which imparts a soft touch to the buttonhole lockstitch suture. . Moreover, instead of ending the final needle drop position of the aforementioned right-side reinforcing seam, the needle will fall to the middle position P6 of the second seam stitching part (lower side) while the next decorative seam or hole lock seam continues, thereby making the thread passing position at Inside the second suture. In the flow chart of Fig. 12, the case where the decorative seam selection data is 丨 is explained according to the shape of the seam shown in Fig. 15.

Invention Description (丨 9) According to this setting, the industrial and consumer company started to decorate the left side of the decorative seam (s 23). By calculating the needle position signal (S-24) of each stitch lockstitching machine, only the distance between the decorative seam and the side seam are used. The number of stitches Nb calculated by the length V is used to form a decorative seam on the reinforcement stitch on the left (S-25). Although the final needle drop position P8 on the left side is moved to the seam start position p9 on the right side, it is also possible to perform a needle drop at the intermediate position P10 in the seam stitching section, as in the case of reinforcing stitches. When the right-side decorative seam is started (S-27), the right-side decorative seam (s-28, s-29) of a given number of stitches Nb is formed on the right-side reinforcement seam in the same manner as in the previous steps S-24, s-25. At the final position P11, it stops at the needle-down position (s-30). This decorative seam, at the same time as the reinforcement seam, when forming the side seam of the buttonhole lockstitch suture, which ~~ 邛 produces a bulging effect along the buttonhole, which is excellent for the buttonhole lockstitch suture. Soft touch. Fig. 13 illustrates the subroutine related to the lock seam. From the final position pii of the aforementioned decorative seam, or the middle position of the center of the second seam part? 12. Move to the starting position P13 (S-31) of the lock seam. The thread tension setting of the side seam is set on the panel 110 to set a strong thread tension for embroidering. The upper and lower thread knots are placed on the center of the side seam on the fabric (s-32). Then, the current to the aforementioned solenoid 60 is increased-and as described above, the holding force for the adjustment discs 66, 67 is increased in an instant. Then, when the left seam (S-33) is started, and the left seam of the set needle (Nc) number is formed once the number of stitches (Nc) is formed by the distance set by the side seam distance data e, the tension of the stitching thread is set. (S-36). This thread tension is set to a weak thread tension so as to become a lock seam, so the current amount of the solenoid is reduced-that is, the adjustment of the disks 66 and 67 in the same manner as described above will reduce the thread in an instant.

By setting the pitch set by the pitch data f of the stitching section, the -fixed stitches number-the first-stitching When sewing (s-38, S-39), the side stitch tension setting (s-40) is made in the same way as above, and the current is increased for the solenoid 60 to increase the clamping force for adjusting the disc. After that, the right stitch (S — 41 to S — 43) with a certain number of stitches (Ne) is formed in the same manner as the left stitch. When the right stitch with a given number of stitches (Ne) is finished, the stitch tension is set again. (S-44), while reducing the current to the solenoid at the same time, reducing the clamping force for adjusting the disc, and thereafter forming a second stitch with a certain number of stitches (Nf) in the same manner as the aforementioned -stitch (S-45 ~ s-47). Thereafter, the amount of current to the solenoid 60 is adjusted by the thread tension setting (s-48) at the end of the stitching, and then stopped at the needle position (§ 49). Thereafter, the feed pulse motor 20 is controlled so as to cut the thread in accordance with the thread cutting sub-process (S 50), and then the same thread cutting mechanism (not shown) is performed with the movement of the pressure plate 15 ) Mechanical action, open and close the thread cutting scissors (the well-known structure) to cut the thread. At this time, adjust the amount of current to the solenoid by setting the tension when the wire is cut. In this embodiment, although it is impossible to mention the order of forming the buttonhole lock seam after the reinforcement seams corresponding to the seams on both sides are formed, the reinforcement of the buttonhole lock seam is formed immediately before the side seams are formed. Sewing is also available. That is, it is sufficient to form a reinforcing seam under the side seam where the suture protrudes outside. In addition, in this embodiment, although the present invention is explained in the case of a lockstitch sewing machine for forming buttonhole lock sutures by using this seam, the paper size of forming buttonholes by using ring stitches is in accordance with Chinese national standards ( CNS) A4 size (210 x 297 mm) ^ -------- ^ --------- ^ (Please read the notes on the back before filling this page) 23 476830 A7 V. Invention Note (21) The lockstitch sewing machine can also be implemented. In addition, the buttonhole lock seam can be one of a sleepy eyehole lock seam and a buttonhole lock seam. In addition, although the pitch and width of the reinforcing seams inputted by the operator are suggested in this embodiment, according to the setting of the pitch and width of the lock seam, the difference (4 different) is automatically set to be more than this. Fine pitch and narrow width are also available. In addition, as for the pitch and width of the decorative seams, the default values may be set in the same manner. In addition, although it is suggested that the adjustment value is input to the preset value from the panel 110, as the thread tension setting of the reinforcing seam and the decorative seam, the operator may reset it from the panel i 10 so as to become a lock seam. Furthermore, in the present embodiment, although it is suggested that a high-density zigzag suture that is narrower than the width of the side seam is used as a reinforcement seam, when the width of the reinforcement seam is set, enter "0" and borrow Reinforcing seams are formed by straight stitching lines that are set to a higher density (smaller) pitch than the side stitches, so that needles can be dropped in the fibers or with a small amount of fibers, so you can use the sewing thread as in zigzag stitching. Restrict the fabric's fibers to achieve the same effect. Although the interval between the above zigzag stitching and straight stitching is necessary depending on the thickness of the fabric fiber, etc., the smaller the spacing, the greater the effect of reinforcement. Next, a second embodiment of the present invention will be described with reference to Figs. 16 to 19. It should be noted that the lockstitching machine to which this embodiment is applied is the same as that shown in Figs. 1-6, and the control block diagram shown in Fig. 7 is also the same. In this embodiment, before the formation of the buttonhole lockstitch suture, the zigzag stitch with a narrower width than that of the side seam or the reinforcement stitch formed by the straight stitch is mostly overlapped.

Description of the invention (25) The clothing of the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints the garment "For the first stitch drop, the width of the reinforcing seam is D + nD," and the rest are the same as in Figure 19. When the overlapping seam of the multiple reinforcement seams is formed at the side seam and the seam formation position, if the needles are dropped to the same position in each reinforcement seam, a texture yarn cut that cuts the fiber of the object to be sewn with the needle will be generated. Breaking, or cutting the thread that was sewn in with a needle, etc., resulting in poor strength. In addition, the sewing of the same place is repeated repeatedly, so the stitches become unstable, resulting in poor sewing due to the suture not being connected and the thread being cut. However, in this embodiment, since the needles do not fall on the same point, defects such as texture yarn cutting and poor sewing can be eliminated, and the quality of the object to be sewn can be greatly improved. Next, a third embodiment of the present invention will be described with reference to Fig. 20. The lockstitching machine to which this embodiment is applied is the same as that shown in Figs. 1-6, and the control block diagram shown in Fig. 7 is also the same. In this embodiment, before the formation of the buttonhole lockstitch suture, a reinforcing seam formed by a zigzag seam or a straight seam narrower than the side seam portion is formed at the left and right side seam forming positions so that these left and right seams can be formed. Each of the starting positions P1, P8 of the reinforcing seam changes in a direction orthogonal to the button hole. In other words, as the setting data item No. 18 that can be set from the operation panel, "the left reinforcing stitch X in the X-direction starting position L," No. 19, "right reinforcing stitch in the X-direction starting position" r, can be set. However, it is assumed that the χγ direction is the direction shown in Fig. 20 ". When reinforcing seams and side seams are applied to the material being sewn, the centers X, 130LC, and 130RC of the X direction of the reinforcing seams 129L and 129R may deviate outward due to the expansion and contraction of the cloth, so that the quality of the sewn product is poor. Impact of the situation. At this time, if the amount of deviation can be determined from the nature of the material to be sewn, the paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) 28 ·· '-------- ^- ------- (Please read the notes on the back before filling this page) Ministry of Economic Affairs., € Printed by the Employees' Consumer Cooperatives of the Property Bureau 476830 A7 — B7 V. Description of the invention (26) According to this embodiment, the X-direction starting positions of the left and right reinforcing seams are adjusted so that the X-direction centers of the reinforcing seams and the side seams are consistent. In FIG. 16, although the “starting position in the X direction of the left reinforcing seam” L and the “starting position in the X direction of the right reinforcing seam” R ′ are shown as items that can be independently set, the left and right reinforcing seams are displayed. The starting position in the X direction can be integrated, and L and R 'can be changed by the same amount. It is also possible to apply the present embodiment to the reinforcing seam and the decorative seam of the first embodiment. That is, R1 'R2 or LI, L2 in Figs. 14 and 15 can be changed. In addition, as in the second embodiment, when the overlapped seam is repeatedly overlapped, the present embodiment is also applicable. That is, R, and L in FIG. 17 can be made variable. [Effects of the Invention] Since the present invention is used, before the formation of the beneficial buttonhole seam or the formation of the side seam portion of the buttonhole lock seam, the reinforcing seam having a smaller distance than the side seam is formed at the aforementioned side seam forming position, so There may be cases where the fibers passing through the button holes cut by the cloth cutter are detached from the button hole lock seam joining line, or the fibers are untied, thereby improving the quality of the product. Since the aforementioned reinforcement seam is formed by a lock seam, it becomes a stronger suture. The aforementioned reinforcement seam is formed by a zigzag seam with a high-density gap narrower in width than the side seam, thereby obtaining a better reinforcement effect. Because of the present invention, before the formation of the buttonhole lockstitch suture, the overlapping seam formed by a zigzag stitch or a straight line with a width narrower than that of the side seam portion is repeated, and is formed on the side continuously. The position of the seam or the seam on the two sides is formed so that the needles do not fall at the same point, so the texture yarn can be cut off and the stitching is not good. The quality of the material can be greatly improved. The paper size is applicable to Chinese national standards.
