The upper sleeve drive shaft 57 is fixed to one end of the upper sleeve drive wrist 58a, and the other end of the upper sleeve drive wrist 58a is pivotally mounted to the upper sleeve mounting shaft 59. The upper socket mounting shaft 59 is slidably supported on a pivot 60 that is releasably mounted to the machine table. An upper sleeve 50 is fixed to the upper end of the upper sleeve mounting shaft 59. The upper sleeve 50 holds the tube 61 for threading the sleeve, and the pin 63 is coupled to the upper sleeve mounting shaft 59 of the upper sleeve driving portion 51 by the screw 59a. The upper sleeve 50 is a sleeve. From the mouthpiece entrance to the spigot horn lead outlet -3- M423704 65 (Fig. 7), the tube 61 for threading the ferrule is assembled to the ferrule 66, and the tube 61 is held by the upper rim. Further, the ferrule wire take-up function is provided by the stationary wire hook 80, the wire take-up device 82 that swings relative thereto, and the ferrule wire introduction port 64a that swings the upper ferrule 50. The upper sleeve opening 50 configured as described above is driven by the upper sleeve opening of the drive shaft 53 to drive the tilt cam 54, the roller 56, and the upper sleeve drive the upper fork drive shaft 57. Elliptical motion is performed on the needle 1 1 1 b. The lower sleeve opening portion 71 for driving the lower sleeve 70 is configured to fix the lower cam drive tilt cam 72 on the drive shaft 53 and to be attached to the lower sleeve drive fork 73 in the lower sleeve tilt cam 72. The roller 74 of the male member. The lower sleeve drive fork 73 is pivotally coupled to the sleeve drive shaft 75 by a pin 76. The lower sleeve opening 70 is fixed to the lower sleeve drive shaft 70. The lower sleeve opening 70 is a sleeve 76b for threading the sleeve from the sleeve line inlet to the sleeve horn collar 66a (Fig. 7). In addition, the wire take-up function is performed by the stationary wire hook 81, the wire take-up 82 with respect to the swing, and the socket line inlet 85 of the swivel sleeve 70. The lower sleeve 70 configured as described above is driven by the lower sleeve driving portion 71 which is driven by the lower sleeve opening of the driving shaft 53 to drive the tilting cam 72, the roller 74, and the lower sleeve driving the lower fork driving shaft 75. So that 70 is synchronized with the needles 11a, lib and the upper sleeve 50 to perform the swinging movement groove sleeve execution, by means of the 55' la, the middle, the mouth drive wheel from the lower jaw outlet groove sleeve line, borrowing 73 ' sets Port-4 - M423704 Further, as shown in Fig. 6, a needle driving lever for driving the needle driving mechanism 87 of the needle holder 88 that holds the needles 11a, 11b by the needle driving eccentric cam 84 provided on the driving shaft 53 is provided. 86. However, in the above-mentioned casing, the structure of the ferrule of the edging sewing machine has been carried out in accordance with the history, and each of the companies manufacturing the edging sewing machine has developed various shapes for the shape of the ferrule and the operating mechanism thereof. Fig. 7 shows an example of the shape of the lower mouth 70 in the above-mentioned socket. That is, the tube 76a for threading the cuff of the lower cuff line T3 is assembled to the cuff groove 76b (Fig. 6) from the lower cuff 70 to the cuff horn lead outlet 66a. Therefore, the lower sleeve 70 is formed to be relatively thick when compared with the lower sleeve of the tube for threading the sleeve which is not assembled with the lower sleeve line T3. Further, the hole 90 of the sleeve horn horn lead outlet 66a of the opening 76a is formed to be inclined toward the nipple collar P2 of the lower hem, and the ferrule of the lower ferrule line T3 can be easily threaded. Moreover, the hole 90 of the spigot horn lead outlet 66a considers the diameter of the tube 76a for the ferrule threading of the lower ferrule line T3, and is relatively large in comparison with the lower sleeve of the tube for which the ferrule is not assembled. diameter of. And at the outlet side of the hole 90 of the spigot horn lead outlet 66a, the horn horn portion surface 91 is taken out from the hole 90 of the spigot collar outlet 66a toward the lower sleeve of the lower nipple line T3 of the cloth sewn on one side. The direction 92 forms a fine guide induction path 93 after shallow planing. -5- M423704 and in the lower sleeve 70, the hole 90 from the spigot collar outlet 6 6a is only slightly separated from the lower sleeve line drawing direction 92, and a notch path 94 is formed into a strip shape to make the upper sleeve The horn collar P1 of the mouth 50 passes oppositely without passing over the lower pocket 70. In the above-described mouthpiece device, when the needles 11a and 11b are lowered from the top dead center and rise from the lowermost point, the nipple collar P2 of the lower mouth 70 picks up the needle thread, and the needle thread is hooked on the lower sleeve 70, and the lower sleeve is closed. 70 is a lower ferrule line T3 which is raised from the lowermost point while the upper ferrule 50 is being advanced, and is taken from the tube 76a of the lower ferrule 70 by the horn collar pi, and the lower ferrule line T3 is hooked. When the upper sleeve 50 reaches the top dead center and then falls backward, the needle Ua, lib descending from the top dead center passes through the upper sleeve line of the line supplied from the tube 61 of the upper sleeve 50, and the lower sleeve is penetrated. 70. After the needle thread that has been retracted from one side is detached from the lower sleeve 70, the upper sleeve mouth 50 is lowered and hooked to the lower sleeve line T3 of the upper sleeve 50 to be detached to form a hem seam.

Description. Referring to Fig. 3 to Fig. 5, for the description of the sewing device of the sewing machine of the present invention, as described above, the lower mouth 8 is threaded to the sleeve of the lower mouth line T3 until the outlet of the spigot horn is 1 〇〇. The tube 48 is assembled to the sleeve groove 8a. Therefore, the lower sleeve 8 is formed to be relatively thick when compared with the lower sleeve of the tube 48 for threading the sleeve which is not assembled with the lower sleeve line T3. Moreover, the hole 1〇1 of the socket of the horn of the horn of the spigot is considered to be the diameter of the tube 48 for threading the ferrule of the lower ferrule 3, and the lower sleeve of the tube 48 for which the ferrule is not assembled is Wear on a larger diameter. The hole 101 of the sleeve nipple collar outlet 100 of the tube 48 is formed obliquely toward the nipple collar 2 of the lower sleeve for easy threading of the sleeve. The reason why the hole 101 of the horn horn lead outlet 100 is formed obliquely toward the lower spigot 2 is that when the ferrule is threaded, the lower ferrule 3 conveyed by the air in the tube 48 is ejected so as not to be subjected to A certain amount of resistance is used for the export of the horns of the horns. In the sewing device of the sewing machine of the present invention, the lower sleeve thread Τ3 is the lower sleeve line leading direction 102 when the upper sleeve opening 7 is taken from the lower sleeve line Τ3 of the lower sleeve 8 when the seam is formed. The horn collar outlet 100 extends toward the cloth. When the lower sleeve line Τ3 is formed in the line seam, the lower sleeve line lead-out direction 102 when the upper sleeve mouth 7 is taken out of the lower sleeve line Τ3 of the lower sleeve 8 means that the lower sleeve line Τ3 is with a predetermined tension. Directly attached to the direction of the cloth. When the seam is formed, the lower sleeve thread Τ3 is generally attached to the cloth with a predetermined tension to form a continuous seam directly or through the upper sleeve 7 -12- M423704. In the sewing device of the sewing machine of the present invention, the spigot horn horn outlet 100 is an outlet of the ventral horn lead sub-outlet 103 which is inserted in the direction in which the lower spigot line is taken out 102. Here, the combination means that the combined sling horn horn outlet 100 and the sling horn horn sub-outlet 103 form one outlet. And in the sewing device of the sewing machine of the present invention, the socket horn horn outlet 100 is formed with a circular hole 104, and the spigot horn collar sub outlet 103 is at 1 ^ embodiment (4th (a)-(b) In the drawing, the through hole 105 is formed, and in other embodiments (Fig. 4(c)-(d)), the groove 106 is formed. The lower sleeve 8 is formed with a notch 107 which is cut into a strip shape from the hole 101 of the collar horn lead outlet 100 and only slightly away from the lower sleeve line take-out direction 102. The collar P1 passes oppositely without passing over the lower sleeve 8. According to the above-described sewing device of the sewing machine, the needle 1 la, 1 lb is lowered from the top dead center, and the φ horn collar P2 of the lower sleeve 8 is drawn from the lowermost point, and the needle thread is hooked on the needle thread. In the state of the lower sleeve 8, the lower sleeve 8 is a lower sleeve line T3 which is raised from the lowermost point while the upper sleeve 7 is advanced, and the lower sleeve opening 8 is taken by the horn collar P1, and the lower sleeve is hooked. When the upper sleeve 7 of the line T3 reaches the top dead center and then retreats downward, the needles 11a, lib descending from the top dead center pass through the upper sleeve line T2 of the upper sleeve 7, and the lower sleeve 8 is made After the needle thread that has been retracted from the lower sleeve 8 is detached and detached, the basic function of the hem seam is formed by the upper sleeve mouth 7 being lowered while being hooked on the lower sleeve line T3 of the upper sleeve 7 . Further, the formation method of the above-mentioned hem seam itself is known (Patent Document - 13 - M423704, 3, 19, and 22). At this time, in the step of taking the lower sleeve line T3 of the lower sleeve 8 with the gusset collar P1 as described above, the lower sleeve line T3 is moved forward according to the lower sleeve opening 8 and with a predetermined tension. The reason why the lower set of mouth line T3 is directly connected to the cloth is to be forcibly induced from the hole of the socket of the horn of the horn of the spigot to the ventral horn lead line outlet 103 and connected to the cloth in the direction of the lower spigot line 102. . Therefore, the lower sleeve line lead-out direction 102 and the lead-out position of the lower sleeve line T3 can be stabilized, and the slanted collar P1 of the upper sleeve mouth 7 can surely take the lower sleeve line T3 of the lower sleeve opening 8 and can be completely completed. Avoid jumpers. Therefore, as in the past, the lower sleeve line is in the hole of the outlet of the horn of the spigot, causing the jump of the line, so that the direction of the lower set of the mouth line and the lead-out position are unstable, and the horn of the upper sleeve is made. The collar can't really take the lower set of mouth lines of the lower mouth and cause the shortcomings of jumpers. According to the above-mentioned sleeve device, the lead-out direction and the take-out position of the lower sleeve line can be stabilized, and the upper sleeve can accurately take the lower sleeve line of the sleeve under the sewing machine and avoid the occurrence of jumpers to form Beautiful seams. In the above description, although the ferrule device is described as a double-needle four-wire edging machine, the sling device can also be applied to a single-needle three-wire edging machine. [Industrial Applicability] The sewing device of the sewing machine can stabilize the take-up direction and the take-out position of the lower sleeve line, and the upper sleeve can accurately take the lower thread of the 14- M423704 sleeve under the sewing machine and avoid the occurrence of jumpers. A beautiful seam is formed, so that a pressurized gas can be suitably used in a hem sewing machine that must be automatically threaded.
