The seam stitching further includes a threading device, and the threading device is operable to cause the lower loop wire τ 15 200825235 to pass through a wire hole 2 lb of the lower wire % 21 . The locomotive driving mechanism (not shown) includes a shaft (not shown) that rotates the motor 5 by driving the sewing machine 5, and a conveying mechanism (not shown in the figure). The transfer mechanism converts the rotation of the upper shaft into a vertical motion and transmits the vertical motion to a needle bar 2 through one of the twisting codes and a crank lever. The two needles 3, 3 are fixed to the needle. One of the lower ends of the needle bar 2. Therefore, when the upper shaft is turned The vertical movement is applied to the needle bar 1〇2 via the transfer mechanism, causing the needles 3, 3 to move vertically. (Upper loop ringing mechanism) The upper loop driving mechanism 10 includes a holding of the upper loop 11 The upper wire ring holds 70 pieces 12 and a supporting member 13 supporting the upper wire ring 15 to hold the workpiece 12 to allow the linear action of the upper wire ring holding member 12 and the rotation of the two axes of the upper wire holding member 12, And an operating mechanism 14, the operating mechanism 14 is fed back to the upper wire loop between the two positions, and the one-wheel 12-hour upper wire ring holding member 12 is a circular rod-shaped member and the upper portion is The spring %11 is held at one end portion (upper end portion). The upper thread loop moves the rear side of the trace through one of the lower thread 襄 21 so that the upper loop loop passes through the edge of the lower loop loop 20 T One of the tip end portions of the upper wire loop 11 is moved to the needle lowering point of the burs 3, 3, and the burs 3, 3 and the burrow thread ΤΙ 'T2 (refer to FIG. 4) pass through the "Heil-up line loop Wire loop.

The RAM 53 is a memory that provides a 10 area of operation of the MPU 51. Various materials related to the stitching operation are backed up in the EEPROM 54. The MPU 51 performs processing operations in accordance with a control program stored in the ROM 52. According to the second exemplary embodiment, when the threading operation start command is input from the threading button 290, the control portion 5 turns the lower shaft 6 to a predetermined rotation angle according to the spindle sensor 280. And the stepping motor 270 is driven to position the air injection unit 23A at the injection position. In other words, the control portion 50 functions as an injection control member. In more detail, when the threading button 290 of the operation panel 60 is depressed, the control portion 50 stops the lower shaft 6 at an angle according to the detection signal 20 transmitted by the spindle sensor 280 (the preset) The rotation angle) at which the lower wire ring 21 interlocking with the lower shaft 6 is positioned at one end of the rotation operation (the position shown in Figs. 4 and 5).

When the retract button 291 of the operation panel 6 is depressed, the control portion 50 moves the outlet hole 112 of the conduit 11 from the threading position according to the data output stored in the r〇m 52. The pulse signal No. 5 required to the retracted position drives the stepping motor 27〇. (Operation of sewing machine) Next, the operation of the sewing machine cartridge according to the second exemplary embodiment will be explained with reference to a flowchart shown in Fig. 9. First, when the threading button 290 is depressed (step S1), a signal indicating that the 10 threading button 9 is depressed is output from the operation panel 60 to the control portion 50. According to the signal, the control portion 5 drives the sewing machine motor $ (step S2) and confirms whether the lower shaft 6 is positioned at the preset rotation angle (step S3). The preset rotation angle is visible to the barrier plate 6a. The position of the lower shaft 6 is set to any rotation angle. According to the second exemplary embodiment, the preset rotation angle is set to an angle of the lower shaft 6, at which the lower wire loop 21 interlocked with the lower shaft 6 is positioned at the rotation of the lower wire loop 21 On one end portion (the rightmost end portion in FIGS. 4 and 5), that is, the extension portion 21a is inserted into the 车, T2 of the bur line formed when the burs 3, 3 are raised upward. The angle of the wire loop. If the lower shaft 6 is not at the preset rotation angle (step S3; NO), the control portion 50 continues to drive the sewing machine motor 5 and repeats the confirmation work until the lower shaft 6 is located at the If the lower shaft 6 is confirmed to be at the preset rotation angle (step S3; YES), the control portion 5〇30 200825235 stops the sewing machine motor 5 (step S4), thereby stopping the lower thread loop. 2i. Thereafter, the cymbal control portion 50 drives the stepping motor 270 in the direction indicated by the arrow e in Fig. 6 (step S5) to move an air nozzle 132 forward to the ejection position (step S6). a lead bar of the coupling element 261 interlocking with the air jet 5 unit 230 121 is rotated in the direction indicated by the arrow A in Fig. 5 so that the outlet hole 2 of the line tube Π 0 is positioned at the threading position. The stepping motor 270 is driven by the pulse signal outputted by the control portion 5〇. The number of the pulse signals corresponds to the distance (moving distance) at which the air nozzle 132 is moved from the standby position to the injection position, and the number 10 of the pulse signals is previously stored in the 1101^52. The control portion 5〇 The stepping motor 270 is stopped after the stepping motor 270 is rotated by a rotation amount corresponding to the preset number of pulses (step S7). A threading operation is performed after the stepping motor 27 is stopped at step S7, When the eject button 291 is depressed (step S9), the control portion 5 驱动 drives the stepping motor 27A in the direction indicated by the arrow F in FIG. 6 (step S9) to make the air nozzle 132 backward. Moving to the standby position (step sl). At the same time, the wire lever 121 interlocked with the air-injecting unit 230 through the coupling element 261 is rotated in the direction indicated by the arrow B in FIG. 4 to make the wire tube 11 The outlet hole 112 is positioned at the retreat The control portion 5 turns the stepping motor 27 to stop after rotating the stepping motor 270 by a rotation amount corresponding to the preset number of pulses in the same manner as the above-described forward movement (step S11). The processing action is ended. (Advantages of the second exemplary embodiment) According to the sewing machine cartridge of the second exemplary embodiment, the wire lever 121 supporting the wire tube 11 and the 31 200825235 air jet single τ ϋ 23 可以 can drive the stepping motor 27〇 is electrically controlled. Furthermore, they can be controlled simultaneously by the engaging element. In other words, the coupling element 261 and the actuation of the coupling element 261 (the stepper motor 270) implement the wire lever 121 and the The air jetting unit 230 is controlled at the same time without adding excessive cost. Therefore, the threading operation is easier to perform than conventional techniques. Therefore, the operability of the sewing machine 1 can be enhanced. (Others) As shown in Fig. 10, a guiding member 167 (recovering member) can be fixed and disposed in one of the bed portions of the sewing machine frame. The guiding member 167 positions the outlet hole 112 of the conduit 110 in the retracted position in accordance with the driving of the sewing machine motor 5. When the sewing machine motor 5 is driven to rotate the lower wire loop 21 through the lower shaft 6 and the underarm loop drive shaft 22, the wire lever 121 has its intermediate portion rotated relative to the lower wire loop 21 The support, 15 also rotates with the lower wire loop 21. When the projection 121e formed on the wire lever 121 is attached to the inclined portion 16% of one of the guiding members 167, the outlet hole 112 will be guided to the retracted position along the inclined portion 167a. In other words, the outlet hole 112 of the conduit 110 can be privately moved to the 5-hook position according to the driving operation of the sewing machine motor 5. Therefore, even if the user forgets to return the outlet hole Π2 of the bobbin 11 to the retracted position after saying that the 20 lower loop loop is passed through the lower loop 22, the user can smoothly switch to the suturing operation. In other words, the user of the sewing machine 1 does not perform a return operation after passing the lower loop wire τ through the lower loop 21 to return the outlet hole 112 of the spool 1 from the threading position to the retracted position. . Therefore, the threading worker 32 can be easily executed. According to the second exemplary embodiment, the rack 261d is disposed at the edge of the coupling member 261 so that the coupling member 261 can be directly driven by the stepping motor 27A. However, another configuration may be used in which at least one of the base 231 and the wire 5 lever 121 is driven by the stepping motor 270, and the base 231 and the wire lever 121 are interlocked by the coupling member 261. Further, the actuator is not limited to the stepping motor, which may be, for example, a solenoid. Furthermore, gears having different rotation speeds or couplings having different lengths may be provided in the coupling portion 10 of the coupling element 161 (261) and the wire lever 121 and/or the coupling element 161 (261) and the base 131 The coupling portion, and thus the distance of movement of the wire lever 121 relative to the moving distance of the coupling element 161 (261) in the Y-axis direction and/or the moving distance of the base 131, may be changed as needed. In a third exemplary embodiment, the wire lever 121 and the air injection unit 13A can be operated by a separate drive element synchronization 15. For example, as shown in Fig. 14, a first stepping motor ST1 (first time) is engaged with an operating plate through a connecting member R1 such as a rack and pinion, and the wire lever 121 is rotated. The operation panel M1 is connected to the wire lever 121 of the bobbin moving mechanism 120. 2〇' As shown in Fig. 15, the second stepping motor ST2 (second actuator) is lightly coupled to the base 131 through the connecting member R2 such as a rack and pinion, and the base 131 is reciprocated mobile. As shown in Fig. 16, the stepping motor and the milk system are controlled by a control portion lock control member to cause the line moving mechanism (10) to operate in synchronization with the air 33 200825235 injection unit 130.
