499523 A7 B7_ 五、發明說明（1 ) 本發明係有關於循環式縫紉機，其具有一縫線修剪裝 置與一工作夾裝置。 其已習知有一種循環式縫紉機包括具有刀刃之一縫 線修剪裝置與一工作夾裝置用於在縫紉之際按壓一工作 織物，該縫線修剪裝置與該工作夾裝置被共同之驅動源驅 動。在此縫紉機中，於循環縫紉結束時，縫線修剪裝置之 縫線修剪作業與工作夾裝置之工作夾舉起動作連續地藉由 驅動該驅動源而被實施。 在使用此種循環式縫紉機之縫紉作業中，縫紉之一第 一循環有時候隨後連續有縫紉之第二循環。例如，如第6 圖顯示之四孔鈕扣在一織物上被縫時，縫線S1首先在二孔 間被形成，且縫線S2循序地在其他二孔間被形成。當縫線 S1與S2連續地被形成時，交叉線X在縫線間出現。當交叉 線X在外觀上被被嫌惡時，該交叉線在形成縫線S1後被縫 成，然後縫線S2被形成。 然而，當縫線修剪在形成縫線S1後被慣常的循環式縫 紉機實施時，工作夾裝置亦連續地向上移動以去除被縫紉 之材料，因而發生下一個縫線之開始位置由所要的位置被 移位之問題。 尤其是在工作夾裝置按壓具有鈕扣被扣於其上之織 物的循環式縫紉機中，工作夾裝置之舉起動作造成織物與 鈕扣一起被舉起，此造成當工作夾裝置再次被降低使得鈕 扣被移位與（或）織物被摺叠的另一問題。其結果為，如針 斷掉的麻煩在下次縫紉有時會發生。後果為舉起工作夾裝

置會需要較長的循環時間，且生產力被降低。 因此本發明之一目標為使用一縫紉修剪裝置與工作夾 裝置用共同驅動源被驅動的循環式縫紉機，藉由僅循環縫 紉結束後不需驅動一工作夾裝置實施縫紉修剪來增加生產 力。 為了解決上述的問題，本發明提供一種循環式縫紉機 (單線鏈形縫法之縫紉機）l〇G，其具有縫線修剪設施（縫線 修剪槓桿6、連接槓桿8、第一連接臂10、第二連接臂11、 活動刀刃13與靜止刀刃）用於修剪縫線、與工作夾舉起設 施（舉起槓桿5)用於為了按壓將被釋放織物而舉起一工作 夾裝置（工作夾機構Ό。 在本發明之第一層面中，該縫紉機包括一驅動構件（驅 動臂4)，其連接每一縫線修剪設施與工作夾舉起設施以依 據該驅動構件之動作位置，及一驅動設施（驅動電磁圈1) 用於在一方向驅動該驅動構件。該驅動構件由一待命位置 至一驅動開始位置以一方向移動以用該修剪設施開始修 剪、至一修剪結束位置以用該修剪設施完成修剪、至一舉 起開始位置以用該舉起設施開始舉起該工作夾、及至一舉 起結束位置以用該舉起設施完成舉起該工作夾。該縫紉機 進一步包括控制設施（CPU 53)用於控制該驅動設施以使在 該修剪結束位置與該舉起開始位置間之位置移動及停止該 驅動構件為可能的。 在本發明之該第一層面下，該修剪作業與該舉起作業 依據該驅動構件移動時接續地被執行。當該驅動構件進一

止，該修剪作業僅可在該修剪作業後無舉起作業下被執 行。 因之，當連續的縫紉在不需舉起作業之此一短距離內 被執行時，被工作夾裝置造成之麻煩不會因僅有修剪作業 而沒有不必要的舉起作業的執行而發生。此提高會加強作 業效率之生產力。 在上面的描述中，「介於修剪結束位置與舉起開始位 置間」之位置包括修剪結束位置、舉起開始位置、及其間 的位置。該舉起開始位置可為大約與該修剪結束位置相同 的位置。 進而，具有插棒、步進馬達等之電磁圈可被用作為一 驅動設施。 在本發明之一第二層面中，該控制設施適用於控制該 驅動設施，使得該驅動構件針對該待命位置移動至修剪結 束位置與舉起開始位置間之某一位置，然後回到該待命位 置。為了使該驅動構件回到該待命位置，可使用該驅動設 施本身之驅動力或彈簧力。 在本發明之一第三層面中，該縫紉機包括該縫線修剪 設施適用於由針延伸至工作織物之線修剪一工作織物、縫

始位置間之某一位置然後回到待命位置時即僅在驅動構 件於修剪作業後回到待命位置時被實施。其結果為，在少 數縫紉循環在不須舉起工作夾裝置的短距離內連續地被 執行的情形中，擦拭作業總是在每一縫紉循環後被實施， 以使由針伸展之縫線端部為自由的以因而達成平順的連 續縫紉。 經濟部智慧財產局員工消費合作社印製 當驅動構件移動至舉起結束位置時，即當工作夾裝置 在修剪作業後以無效的被選擇而被舉起時，擦拭作業未被 實施。然而，該擦拭作業在此情形並非必要的，原因在於 由針伸展之縫線端部藉由在工作夾裝置被舉起時去除該 工作織物而變成自由的。因之，在工作夾裝置的舉起作業 之際的不必要之擦拭作業可藉由選擇無效的擦拭作業而 被消除。 在本發明之第四層面中，該驅動設施包含一電磁圈， 該舉起設施具有一耦合部位（突出物5a)與工作夾裝置之 部位耦合，以在驅動構件移動至舉起開始位置時透過該耦

即，該驅動構件以如上述控制之特定電流停留在舉起開始 位置。 在此情形中，各種控制的方法將被採取。例如，被供 應至電磁圈之有效的電流值藉由改變一串脈衝電流之作 用比而被控制。另一例子為，該電流值本身可被一電流控 制電路控制。 有關「某一期限」，若舉起作業能用較小的電流在開 始移動該驅動構件後被完成，該電流值可在驅動構件到達 修剪結束位置前被改變為該較小的電流。 在本發明之第五層面中，本發明被應用至一鈕扣縫紉 機用於在一織物上縫紉一個四孔鈕扣。該控制設施控制縫 紉機的方式為，在於該織物上縫紉一對鈕扣孔之一第一次 縫紉後，該驅動構件由待命位置移動至修剪結束位置與舉 起開始位置間之位置並在修剪後回到待命位置，在於該織 物上縫紉另一對鈕扣孔之一第二次縫紉後，該驅動構件由 該待命位置移動至該舉起結束位置。 依據本發明之第五層面，在縫紉一個四孔鈕扣時，修

Description of the invention (1) The present invention relates to a circular sewing machine, which has a stitch trimming device and a work clamp device. It is known that a circular sewing machine includes a stitch trimming device having a cutting edge and a work clamp device for pressing a work fabric during sewing. The stitch trimming device and the work clamp device are driven by a common drive source. . In this sewing machine, at the end of the cycle sewing, the stitch trimming operation of the stitch trimming device and the work clamp lifting operation of the work clamp device are continuously performed by driving the driving source. In a sewing operation using such a circular sewing machine, one of the first cycles of sewing is sometimes followed by the second cycle of sewing in succession. For example, when the four-hole button shown in Fig. 6 is sewn on a fabric, the seam S1 is first formed between the two holes, and the seam S2 is sequentially formed between the other two holes. When the sutures S1 and S2 are continuously formed, a cross line X appears between the sutures. When the cross line X is disgusted in appearance, the cross line X is sewn after forming the seam S1, and then the seam S2 is formed. However, when the stitch trimming is performed by the conventional cycle sewing machine after the stitch S1 is formed, the work clamp device is also continuously moved upward to remove the material being sewn, so that the start position of the next stitch is changed from the desired position. The problem of displacement. Especially in the circular sewing machine in which the work clamp device presses the fabric with the buttons fastened thereto, the lifting action of the work clamp device causes the fabric to be lifted together with the buttons. Another problem is shifting and / or fabric being folded. As a result, troubles such as needle breakage may occur next time sewing. The consequence is that the work is clamped.

Description of the Invention (2) The installation will require a longer cycle time, and productivity will be reduced. Therefore, an object of the present invention is to use a circular sewing machine driven by a common driving source for a sewing trimming device and a work clamp device, and increase productivity by only performing sewing trim without driving a work clamp device after the end of the cycle sewing. In order to solve the above-mentioned problems, the present invention provides a circular sewing machine (single-thread chain sewing method) 10G, which has a stitch trimming device (the stitch trimming lever 6, the connecting lever 8, the first connecting arm 10, the first The two connecting arms 11, the movable blade 13 and the stationary blade) are used for trimming the suture, and the work clamp lifting device (lifting lever 5) is used for lifting a work clamp device (work clamp mechanismΌ) for pressing the fabric to be released. In the first aspect of the present invention, the sewing machine includes a driving member (driving arm 4), which connects each suture trimming facility and work clamp lifting facility according to the operating position of the driving member, and a driving facility ( The driving solenoid 1) is used to drive the driving member in one direction. The driving member is moved from a standby position to a driving start position in one direction to start trimming with the trimming facility, and to a trimming end position to be completed with the trimming facility.

However, since the driving member may stop between the trimming end position and the lifting start position, the trimming operation can only be performed After the trimming operation, no lifting operation is performed. Therefore, when continuous sewing is performed within such a short distance without lifting operation, the trouble caused by the work clamp device will not be caused by only the trimming operation. Without unnecessary lifting Occurs during execution. This improvement will enhance the productivity of operation efficiency. In the above description, the position “between the trimming end position and the lifting start position” includes the trimming end position, the lifting start position, and the positions therebetween. The The lifting start position may be about the same position as the trimming end position. Furthermore, an electromagnetic coil having a plunger, a stepping motor, etc. may be used as a driving facility.

Description of the invention (4) (Please read the precautions on the back before filling this page) Used to control the wiping operation, The method is that if an effective wiping operation is selected, the wiping operation is always performed after trimming, and if an invalid wiping operation is selected, the wiping operation is performed when the driving member is moved from the standby position to the lifting end position and then returned. It is not performed, and the wiping operation is performed when the driving member is moved from the standby position to the trimming end position and the lifting start position and then returns to the standby position. According to the third aspect of the present invention, even if an invalid wiping operation is selected, when the driving member moves to a position between the trimming end position and the lifting start position and then returns to the standby position, the driving member is only trimmed Implemented when returning to standby after work. As a result, in the case where a small number of sewing cycles are continuously performed within a short distance without lifting the work clamp device, the wiping operation is always performed after each sewing cycle so that the end of the thread extended by the needle The part is free so as to achieve smooth continuous sewing. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs When the driving member is moved to the lifting end position, that is, when the work clamp device is lifted with an invalid selection after the trimming operation, the wiping operation is not performed. However, this wiping operation is not necessary in this case because the end of the suture stretched by the needle becomes free by removing the work fabric when the work clamp device is raised. Therefore, an unnecessary wiping operation during the lifting operation of the work clamp device can be eliminated by selecting an invalid wiping operation. In a fourth aspect of the present invention, the driving facility includes an electromagnetic coil, and the lifting facility has a coupling portion (a protrusion 5a) coupled to a portion of the work clamp device to transmit when the driving member moves to the lifting start position.

From the starting position. According to a fourth aspect of the invention, the invention is particularly implemented. That is, the driving member stays at the lifting start position with a specific current controlled as described above. In this case, various control methods will be adopted. For example, the effective current value supplied to the solenoid is controlled by changing the ratio of a series of pulsed currents. As another example, the current value itself can be controlled by a current control circuit. Regarding the "certain period", if the lifting operation can be completed with a small current after starting to move the driving member, the current value can be changed to the smaller current before the driving member reaches the trimming end position. In a fifth aspect of the invention, the invention is applied to a button sewing machine for sewing a four-hole button on a fabric. The control device controls the sewing machine in such a manner that after one of a pair of button holes is sewn on the fabric for the first time, the driving member is moved from the standby position to a position between the trimming end position and the lifting start position and returns after trimming To the stand-by position, after the second sewing of one of the other pair of button holes is sewn on the fabric, the drive member is moved from the stand-by position to the lift end position. According to the fifth aspect of the present invention, when sewing a four-hole button, the trimming device does not need to drive the single-line chain stitch method only after trimming a pair of button holes. 297 mm) (Please read the precautions on the back before filling out this page) _install ------ 丨 --order --------- line Printed by the Ministry of Intellectual Property Bureau's Consumer Cooperatives 499523 A7 __B7 _ V.

The horizontal portion of the connection plate 9 is rotatably connected to one end portion of the first connection arm 10, and the other end portion of the arm 10 is fixed to one end portion of the second connection arm 11. As shown in FIG. 3, the other end portion 11a of the second connecting arm 11 of the needle plate 12 and the movable blade 13 rotatably supported relative to the needle plate 12 through the vertical pin 23 are rotatably connected. The stationary blade 14 and the movable blade 13 are fixed to the needle plate 12 so as to face each other with a pinhole 25 therebetween. The counterclockwise rotation of the movable blade 13 in FIG. 3 allows the needle thread passing through the pinhole 25 to be grasped, resulting in the result that the needle thread is trimmed by the coupling with the stationary blade 14. Thus, the suture trimming facility includes a suture trimming lever 6, a connecting lever 8, a first connecting arm 10, a second connecting arm 11, a movable blade 13 and a stationary blade 14.

Description of Invention (10) -------------- Installation --- (Please read the back first (Notes on this page, please fill out this page again)) When viewed from above, the wiper 45 is located on the left side of the needle 30 as shown in FIG. 5 and has a protruding portion 45a extending to the right at the lower end. The mounting plate 46 is fixed to one end portion of the robot arm 102, and the wiper 45 is rotatably mounted to the other end portion of the wiper 45 through the pin 24b. With this configuration of the wiper device 40, when the plunger 43 is driven toward the direction B against the urging force of the spring after the suture is trimmed, the wiper 45 rotates around the pin 2 4b in the direction C as indicated in FIG. 4 , Allow the suture T to be wiped off by the protruding portion 45a, and the suture T is stretched from the needle 30 to below the fabric. After wiping the suture, the plunger 43 returns to its standby position with spring force. Meanwhile, the effective or ineffective wiping operation of the wiper device 40 after the stitch trimming can be selected through the operation panel 52. When "active" is selected, the device 40 always works after trimming, and when "inactive" is selected, the device 4G basically does not work. ; Thread · In the machine 100, the button caught by the button holder 21 is sewn on the fabric pressed between the button holder 21 and the needle plate 12. The device 70 operates as follows after sewing. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the driving solenoid 1 is energized, the plunger la is pulled against the driving force of the first spring 2 and the driving arm 4 is moved in the direction of the arrow P to allow the stitches to be trimmed The lever 6 and the lift lever 5 start to rotate counterclockwise. The rotation of the lever 6 causes the first connecting arm 10 and the second connecting arm 11 to move in the direction of the arrow Q through the connecting lever 8 and rotates the movable blade of FIG. 3 counterclockwise to form a gap between the stationary blade 14 and the movable blade 13 Line trim. During the trimming operation, the counterclockwise movement of the lever 5 raised the highlight -13-This paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) 499523 A7 B7 _ V. Description of the invention (η) 5a moves upwards, but during the initial movement of the lever 5 to the running gap E, the protrusion 5a is not coupled to the hook 7a. When trimming is completed, i.e. when the lever 5 runs the gap E, the protrusion 5a is coupled with the hook 7a. Further operation of the lever 5 allows the hook 7a to be lifted against the urging force of the second spring 15. The lifting of the hook 7 a allows the clamp mechanism 7 to rotate about the support shaft 7 b to separate the clamp 21 from above the needle plate 12. When the driving arm 4 stops at a predetermined position, the mechanism 7 also stops rotating. In this state, the buttons and fabric can be removed. At the same time, when the mechanism 7 is lifted (raising operation), the action of the driving arm 4 in the direction P causes the trimming lever 6 to continue to rotate, but the shape of the cam groove 8a prevents the connecting lever 8 from turning. When the drive solenoid 1 is turned off, the device 70 returns to its standby position. And the wiper device 4G performs a wiping operation after the stitches are trimmed, which pulls out the stitches stretched by the needles 30 over the fabric for the next sewing. As described above, in a series of suture trimming and clamp lifting operations, the suture trimming operation is carried out by moving each relevant part against the appropriately weak driving force of the first spring 2 while the clamp lifting The driving force of the working system against the strong force of the second spring 15 is implemented to lift the entire clamping mechanism 7, and the required lifting force is much stronger than that of the trimming operation. In the above-mentioned operation of the sewing device 70, the control of the trimming operation without lifting operation can be selected when necessary. For example, in the case of using the machine 100 of the present invention to sew a 4-hole button BT without cross stitching, no lifting operation is required when sewing the sewing thread S2 followed by continuous sewing of the sewing thread S1, so only the trimming operation is performed . In this case, the seam S 2 is sewn without the need to wipe after the seam S1 is trimmed—14-This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) (Please read the back Please fill in this page again for attention) Packing-Order II! !! Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 499523 A7 B7 V. Description of the invention (l2) The end of the trimmed suture is left at the button hole Η in the fabric and the cross stitch will appear. Therefore, the wiper device 40 is always operated with the wiper solenoid 42 after trimming, even when an “invalid” wiping operation is determined through the operation panel 52. Now, a description of button sewing of a 4-hole button without cross stitches will be given with reference to the flow circle of FIG. 7 and the time circle of circle 8. The timing chart of Fig. 8 shows that the relationship between the position of the driving arm 4 and each step of the sewing process is parallel to the operating position of the wiper link 44 of the driving wiper 45. The horizontal axis of Fig. 8 represents the time corresponding to the sewing step of Fig. 7, and the vertical axis represents the operation positions of the arm 4 and the link 44 respectively. As described above, the operation of trimming and clamping the suture is carried out as if the arm 4 is driven to move the electromagnetic coil 1 in the direction of P in Fig. 2 and driven. That is, the position of the arm 4 in the P direction has some relationship with a series of sewing processes. The position where the arm 4 starts trimming with the suture trimming facility is indicated as the "trimming start position", the position where the clamp mechanism 7 is started to be lifted by the lift lever 5 is the "lifting start position", and The position is "lifting end position". In the example shown in Fig. 8, the standby position is almost the same as the trim start position, and the trim end position is the same as the lift start position. And the parallel presentation of the link 44 and the arm 4 shows the time of the wiping operation in the trimming operation. Fig. 7 is a flowchart of the sewing process of trimming the 4-hole button BTT of Fig. 6 on the fabric. This process is divided into a first process of forming the seam S1 (first sewing) and a second process of forming the seam S2 (second sewing).

Description of the invention (13) The folder mechanism 7 was Position the uppermost position (the lifting end position in Figure 8) to place the buttons and fabric, with the arm 4 near the solenoid 1. The wiper link 44 is also in the uppermost standby position in Fig. 4 with spring force. Referring to Fig. 7, when the operator sets the fabric and buttons and activates the enabling pedal 51, sewing of the stitch S1 is started. First, in step S1, the driving solenoid 1 is turned off to move the arm 4 toward the R direction in FIG. 2 and touch the stopper 3, and return to the standby position shown in FIG. 8. The device 70 also returns to its standby position. Next, in step S2, the first process is started (time t1 in the eighth circle), and the sewing motor 59 is started. Step S3 checks whether a trimming command is output until the stitch S1 is completed. If the trimming command is detected after sewing, the stitch trimming process A (Fig. 10) is performed at step S4, and the suture wiping operation (Fig. 9) is performed at step S5. Under these operations, the arm 4 starts to move in the P direction in the second figure (after time t2), and reaches the trimming end position. The arm 4 remains in the trimming end position for a certain period of time, and then (after time t3 in Fig. 8) is closed with the electromagnetic coil 1 and returns to the standby position.

In step S8, this step is repeated in the same manner as in step S3 until the trimming command is detected after the sewing is completed, and then the step proceeds to step S9 to check whether a valid or invalid wiping job is determined. If the "effective" wiping job is not selected, the trimming process B is performed only at step S10, and if the "effective" wiping job is selected, the wiping process (at step S12) and the trimming process B (at step S11) are executed, the The trimming process B includes a clamp lifting operation. These operations are carried out as shown in Fig. 8. From the stand-by position (at time t5), the arm 4 is moved to the trimming end position, and further to the lifting end position. When the "effective" wiping operation was previously selected by the operator, both the trimming operation and the wiping operation are performed in steps S11 and S12, where the wiper link 44 is moved from the standby position to the wiping end position, and as shown in Fig. 8 Reply. Finally, the motor stops at step S13 to end the process. Figure 9 shows the suture wiping process. Step S21 checks whether some time (here, 50 ms) has elapsed. This time allows waiting for the trimming to end. After this certain time, the wiper solenoid 42 is driven to start the wiping operation at step S22, and the process proceeds to step S23 to check whether some time (here, 50 ms) has passed. This time here determines the time from when the wiper 45 starts moving to when the suture is wiped off. Then in step S24, the electromagnetic coil 42 is turned off to end the wiping operation. As shown in Fig. 8, during the sewing operation of Fig. 7, the arm 4 remains at its trimming end position after the first process, and advances -17 after the second process.-This paper size applies Chinese national standards ( CNS) A4 specification (210 X 297 mm) ------------- install -------- order ------ 1 (please read the precautions on the back first (Fill in this page) 499523 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of Invention (15) Move to the lift end position in one step. Fig. 10 shows a flowchart of the stitch trimming process corresponding to step S4 of Fig. 7. The stitch trimming process A starts at step J1, which drives the solenoid 1 with a 100% action ratio. Step J2 checks if some time (60ros in this case) has passed. If not, this step is repeated. If it has, the process proceeds to step J3. The effect ratio is reduced to 50% in step J3, and the process moves to step J4, which waits for a period of time (here 24 Gms) to completely complete the suture trimming. Then in step J5, the electromagnetic coil 1 is turned off to end the process. When the electromagnetic coil 1 is turned off, such as the plunger la, the arm 4 and the like, the driving force of the first spring 2 is returned to its standby position. This is the reason for driving the solenoid with a 100% action ratio in step J1, and the starting force of the moving arm 4 against the force of the first spring 2 needs a suitably strong force. However, the period of driving with a 100% action ratio is limited to a certain time (60ms here), and immediately thereafter is reduced to 50%, and its creative power is insufficient to lift the clamp mechanism 7. As a result, the arm 4 remains at the position where the protrusion 5a is just coupled with the hook 7a, that is, at the start-up position. Fig. 11 is a flowchart showing the stitch trimming process B corresponding to steps S1G and S11 of Fig. 7. First, at step J11, the driving solenoid 1 is energized with an effect ratio of 100%. Next, step J12 checks whether the electromagnetic coil 1 has been driven for some time (here, 75ms). If not, the decision step is repeated, and if so, the process proceeds to step J13. Continue to take longer than the flow chart in Figure 10-18-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). -------- ^ ------ --- ^ (Please read the notes on the back before filling out this page) ^ 523 ^ 523 Hr Printed by A7, Consumer Cooperatives, Intellectual Property Bureau, Ministry of Economic Affairs ^ _E_ V. Invention Description (ι〇 (75ms) with 100% effect ratio The reason for driving the electromagnetic coil 1 is to lift the clamp mechanism 7 after the stitch is trimmed. When the mechanism 7 is lifted, the driving effect ratio is reduced to 5G% in step J13 to maintain the lifted state, and the stitch is trimmed The process ends. When using the machine 100 of the present invention to sew 4-hole buttons on a fabric, after the first sewing process, the driving solenoid 1 is first energized by the 100% action ratio of the pulse current, and after 60 ms Reduced to 50% effect ratio, it is not enough to lift the clamp mechanism 7 and allow the arm 4 to stop at the lifting start position. As a result, only the suture trimming operation does not require unnecessary mechanism 7 after this first process The lifting operation is performed, and the trouble of button position displacement and fabric folding caused by the lifting of the mechanism 7 will not occur. This results in higher productivity and enhanced operation efficiency. If an "invalid" wiping operation is selected through the control panel 52, the wiping operation is not performed when the arm 4 moves to the lifting end position, that is, the lifting of the mechanism 7 is followed by Suture trimming. Since the trimmed end of the suture stretched by the needle 30 becomes free when the material being sewn is removed, the wiping operation is generally unnecessary. Therefore, selecting an invalid wiping operation as described above allows the Eliminate unnecessary wiping operations at the time of the lifting mechanism 7. On the other hand, even if an invalid wiping operation is selected, the wiping operation is only after the trimming of the first process and the arm 4 moves to the position where it is lifted up and returns to standby The position is executed. As a result, the trimmed suture stretched by the needle 30 becomes free after the first suture and smoothly starts the second sewing process. Alternatively, although the energization of the driving solenoid 1 is enabled The action ratio is No. 10 and -19-This paper size is applicable to China National Standard (CNS) A4 specification (210 X 297 mm) ------------- installed ------ II order --------- Line (Please read the notes on the back first (Fill in this page again) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 499523 A7 ___ Β7 ___ V. Description of the invention (17) The second step of Figure 11 is given as 100% and 50%, which can be changed to more than three steps, and The driving period of each step can be appropriately set. In addition, the magnetic force of the electromagnetic coil 1 can be changed by driving the current value through the current control circuit, which is not controlled by changing the action ratio as in this embodiment. As the above-mentioned embodiment is used as a driving facility, a stepping motor may be adopted as an alternative as shown in FIG. Fig. 12 shows a suture trimming and clamp lifting device 80 according to another embodiment of the present invention. Since the device 80 is similar to the device 70 shown in the second circle, similar component numbers indicate similar parts, and only differences will be described. In the device 80, a stepping motor 81 is used as a driving facility. The pinion gear 82 is fixed to an output shaft of the motor 81. The bearings 83 and 83 are fixed to the machine frame. These bearings 83 and 83 slidably support the rail 84 coupled to the pinion gear 82, and the top end of the rail 84 is fixed to one end of the driving arm 4. The driving of the motor 81 causes the arm 4 to move in the P or R direction through the rail 84. In this case, the arm 4 is moved by a desired amount with a pulse signal given to the motor 81, and the same operation as the embodiment shown previously in the eighth circle is achieved. The present invention is not limited to the embodiments described above, and various changes can be made. For example, in these embodiments, the trimming end position may be substantially the same as the lifting start position, but the lifting start position may be sequentially set after the trimming end position. These embodiments are applied to 4-hole button sewing including two processes, but the present invention can also be applied to other sewing including three processes. -20-This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ----------- installation -------- order ------- --Line i ^ w., * (Please read the precautions on the back before filling out this page) 499523 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Invention Description (18) In addition, the circular sewing machine is not limited to Single-thread chain stitch sewing machine. According to the first and second levels of the present invention, since the driving member may stop between the trimming end position and the lifting start position, the trimming operation can be performed only without the lifting operation after the trimming operation. Therefore, when continuous sewing is performed within such a short distance without lifting operation, the trouble caused by the work clamp device does not occur because only the trimming operation is performed without the unnecessary lifting operation. This improvement will enhance productivity of operation efficiency. According to the third aspect of the present invention, even if an invalid wiping operation is selected, when the driving member moves to a position between the trimming end position and the lifting start position and then returns to the standby position, the driving member is only trimmed Implemented when returning to standby after work. As a result, in the case where a small number of sewing cycles are continuously performed within a short distance without lifting the work clamp device, the wiping operation is always performed after each sewing cycle so that the end of the thread extended by the needle The part is free and often prevents the formation of cross stitches. When the driving member is moved to the lifting end position, that is, when the work clamp device is lifted up with an invalid selection after the trimming operation, the wiping operation is not performed. However, this wiping operation is not necessary in this case because the end of the suture stretched by the needle becomes free by removing the work fabric when the work clamp device is raised. Therefore, an unnecessary wiping operation at the time of the lifting operation of the work clamp device can be eliminated by selecting an invalid wiping operation. According to a fourth aspect of the invention, the invention is particularly implemented. That is, the driving member stays at the lifting start position with a specific current that is initially supplied, and then after a certain period of time, the current used is more than that of the supplied -21-This paper size applies to the Chinese National Standard (CNS ) A4 size (210 X 297 mm) ------------------------- Order --------- line (Please read the note on the back first (Fill in this page again)
