C jttr Ji Conventional background "Left and right" or "right side" and "left side" in this specification refer to the left or right or left and right sides of the feed direction γ in each drawing. The conventional shuttle device of the double needle lockstitch sewing machine will be described with reference to Figs. 5 to 7. The double-needle lockstitch sewing machine includes two needles 3, 4 arranged on the left and right, and a pair of left and right shuttles 3, 4 arranged on each of the needles and having a hook tip 3a, 4a formed to catch the second loop of each needle. . In the double needle machine shown in Figure 5, the needle (left needle) is placed on the left side with respect to the feeding direction γ! The hollowed-out pla is placed to the left, and the needle (right needle) 2 placed on the right is placed to the right, that is, the hollowed-out parts la, 2a are placed to the outside (Fig. 5). When the pin 2 rises from the most attractive, on the sides of these hollowed-out portions la, 2a, ten coils will be formed. In FIG. 5, 'the left and right shuttles 3 and 4 are rotated in the clockwise direction R1, and the shuttle central% of the shuttle (left shuttle) 3 arranged on the left side passes through the hollowed portion 1a formed by the left needle 2. To capture the needle loop, the shuttle (right shuttle) 4 arranged on the right side reads through the hollowed-out portion M formed on the right side of the right needle 2 and captures the clothing in the feeding direction γ. In needle 1, the left and right pins 7, 8 are formed. When the pin hole of 2 is placed, the end face is pin 5 and 5 of the needle. Then, when the positional relationship between the needles 丨, 2 and shuttle 3, 4 as shown in FIG. 5, since each needle thread 5, 6 passes through the left and right as shown in FIG. 5 (b) and 5 (〇㈤). The thread direction of needle 2 is symmetrical to the left and right, so the twist direction of needle thread 5 and 6 is opposite to the left and right needles 丨 and 2 of the pinhole. Therefore, when using Z twist or S check, one kind of thread is used as When the needle threads 5 and 6 on both sides are stronger than the strong twist of the needle thread of one needle, the twist of the needle thread of the other needle is weaker. Therefore, the fineness of the left and right needle threads sewn into the object to be sewn becomes inconsistent. Uniformity, the stitches are not beautiful, and the quality of the product is reduced. At the same time, the needle thread of the needle with a strong twisting thread may cause the sewing failure caused by thread breakage and needle pitch disorder (skew, skip stitch). The patent publication No. 2-15240 discloses the invention shown in Fig. 6 (a) to solve the above problems. That is, the structure and arrangement of the right needle 2 and the right shuttle 4 and the rotation directions of the two shuttles 3 and 4 are It is the same as that shown in FIG. 5, but the left needle 1 is configured to arrange the hollowed part 1a to the right, and the left shuttle 3 is configured to capture and form The loop on the right side of the left needle 1. The left shuttle 3 shown in FIG. 6 is arranged so as to capture the stitch coil on the side opposite to the shuttle center 3c with respect to the needle 1 as the outer loop shuttle. In the device, as shown in Figure 6 (b) and Figure 6 (c), because the left needle 1 is threaded from the left side of the needle 1 to the right, the right needle 2 is also threaded from the left side of the needle 2 to the right. Therefore, when the left and right stitches 7 and 8 are formed, if the needle threads 5 and 6 are pinched in the needle holes of the needles 1, 2, the direction in which the thread enters the needle holes is the same on the left and right. Therefore, even with Z twisted needle threads 5, 6. It is also possible to make the thickness of the left and right stitches 7 and 8 uniform. Also, as disclosed in Japanese Patent Laid-Open Publication No. 8-332292, as shown in FIG. 7, the rotation directions of the left and right shuttles 3 and 4 are different, and The structure in which the needles 5 and 6 are arranged in the same manner as shown in Fig. 5 so that the hollow portions 1a and 2a face outward. That is, "if the left shuttle 3 rotates in the counterclockwise direction R2, the tip 3a of the shuttle will pass through the arrangement toward Fig. 7 The hollowed-out portion ia of the left needle 1 on the left side captures the loop formed on the left side of the left needle 1. On the other hand, if the right shuttle rotates clockwise R1, the shuttle tip 4a will pass It is positioned toward the hollowed portion 2a 'of the right needle 2 on the right side of FIG. 7 and captures the stitch formed on the right side of the right needle 2. However, it is well-known that in such a lockstitch sewing machine, the direction of formation of the needle stitch may be different. The catching direction of the coil (the direction of rotation of the shuttle) will cause the formation of a tie stitch. That is, if it is a conventional example shown in Figs. 6 and 7, pin 7 will form a tie as shown in Fig. 8 Seam marks. Therefore, there will be a difference in the tightness of the suture or a difference in wrinkles at the left and right stitches 7. Therefore, the object of the present invention is to provide a double needle that responds to the unevenness of the left and right stitches due to thread inspection. The shuttle device of the sewing machine, in which the right stitches form the perfect stitches of the double-needle j-fork-song sewing machine. The invention discloses the shuttle device of the juvenile sewing machine, which includes a double needle with a μ purpose. Each pin of the lock is configured with two needles for capturing the centroid: and the right-to-shuttle, and the left of the needle tip of the needle coil on the right = And while the right side Α 疋 turns, you can capture the configuration; ^ the right line of the right needle It is specially designed for the needle to be arranged so that the hollowed part faces the right side, and to make it possible to capture the needle placed on the left side while rotating the above-mentioned foot on the left side and the shuttle on the left side against the direction of 591,149 clocks.

Fig. 8 is a perspective view for explaining stitches formed by the shuttle device of the conventional example shown in Figs. 6 and 7; 20 [Embodiment] Embodiments of the invention The following describes the embodiment of the shuttle device of the double-needle lockstitch sewing machine according to the present invention with reference to Figs. 1 to 3. The shuttle device includes two needles 11, 12 arranged on the left and right, and a pair of left and right shuttles 13, 14 arranged on each of the needles corresponding to 8 591149. As mentioned above, the "left and right", "right", "left", and "clockwise" and "counterclockwise" directions refer to the left, right, left, and clockwise, counterclockwise, Clock direction, left and right, clockwise direction R1, counterclockwise direction R2 in each figure are equivalent to this. The needles 11 and 12 are fixed to a needle bar 10 which is linked to a main shaft of a sewing machine which is not shown in the figure. In addition, the needle (left needle) u disposed on the left side and the needle (right needle) 12 disposed on the right side are disposed with the hollowed portions 丨 a, 12a toward the right. In addition, the shuttle (right shuttle) 14 disposed on the right side can rotate the clockwise direction ri, and can capture the coil on the right side of the right needle 12 by the shuttle tip 14a. On the other hand, while the shuttle (left shuttle) 13 arranged on the left side rotates in the counterclockwise direction R2, the left needle 丨 丨 the right coil can be captured by the shuttle tip 13a. That is, 'the left shuttle 13 is a shuttle (outer scroll shuttle) whose capture coil is located on the side away from the shuttle center 13c with respect to the needle u. 15 A notch portion 13b is formed at the upper end of the base of the shuttle tip 13a of the left shuttle 13 to open upward. When the left needle π rises, the left needle η rises through the notch 1 (notch groove) 13b. That is, the notch portion 13b is a groove that is used when the left needle 11 rises to allow the needle to pass to prevent collision with the base of the shuttle tip. 20 If the shuttle device according to this embodiment is shown in Figure 1 (b), the thread of the left needle 11 is from the left side of the needle 11 to the right, and the thread of the right needle 12 is also from the left side of the needle 12 to the right. , So it is not symmetrical as the conventional example shown in FIG. 5. Therefore, as shown in Fig. 4, the left and right stitches 17, 18 formed by this embodiment form perfect stitches. Therefore, as in the conventional examples shown in Figs. 6 and 7, there is no difference in the tightness between the left and right stitches or wrinkles. / 、 Also, as shown in FIG. 1 (C), when the left and right stitches 17 and 18 are formed, the direction in which the five pairs of needles 11 and 12 hold the thread 15 and 16 is the same direction as the left and right stitches 11 and 12. Therefore, regardless of whether z-twisted or s-twisted threads are used as the stitches 15, 16, the left and right stitches 17, 18 can be made uniform. The above is a description of the present invention according to the embodiment shown in the figure. However, the present invention is not limited to the foregoing embodiment, but can be modified in various ways. For example, the other implementation type is provided with a notch on the shuttle tip, but it can also be easily knocked out. 10 A sufficient gap can be formed between the shuttle body and the shuttle tip to prevent the needle and the shuttle tip from rushing. As mentioned above, according to the present invention, the shuttle device of a double-needle lockstitch sewing machine includes two needles arranged on the left and right, and 15 needles corresponding to each needle configuration and useful for capturing the needles formed on each needle. A pair of left and right shuttles of the needle tip of the needle coil, and the hollow portion of the needle disposed on the right side is arranged to the right, and the shuttle disposed on the right side can be rotated clockwise to capture the right coil of the needle disposed on the right side. It is characterized in that the needle arranged on the left side is arranged so that the hollowed portion faces the right side, and the shuttle arranged on the left side is rotated counterclockwise to capture the right coil of the needle arranged on the left side. Therefore, even if Z twist or S twist is used for the left and right stitches, it is still possible to prevent poor sewing due to uneven left and right twists, and also to make perfect stitches on both the left and right stitches. If the notch of the needle is formed on the tip of the shuttle arranged on the left side, it is possible to prevent the conflict with the tip of the shuttle arranged on the left side when the left needle is raised. 10 591149 [Brief description of the drawings] The first figure is a schematic diagram for explaining the implementation mode of the shuttle device of the double-needle lockstitch sewing machine of the present invention, (a) is a plan view, (b) is a front view of the needle, ( c) is a plan view of pins and pins. 5 Figure 2 is a perspective view of this embodiment.
