Prior Art J. Heretofore, a sewing machine such as an embroidery sewing machine that moves a cloth in the XY direction without using a feed tooth and sewn is prevented from rising and wrinkling with the bur by the friction with the bur. The inner presser device for pressing the periphery of the burring portion of the sewing material to the lower side when the bur is raised is installed. The device usually presses the sewing material to the lower side with the inner presser foot when the burr starts to rise away from the sewing material, and the inner presser foot rises together with the bur when the bur is completely lifted away from the tamper. The __ device, there is currently an adjustable material wheel or a spinning wheel = the inclination angle of the connecting rod of the rocking body that moves the inner pressing foot up and down, so as to adjust the inner leg device of the inner leg height of the needle plate (for example, Participation 1). Less...,, 旰 At this time, the movement path of the inner presser foot and the bur is as shown in Fig. 13. The third dimension is a diagram in which the horizontal angle of the trajectory of the bur is shifted by the horizontal axis and the longitudinal jin is drawn. Here, the upper shaft angle refers to the turning angle with respect to the upper shaft reference position. - In general, the sewing machine will be connected to the bur by the Threader passing through the bur and the β foot after the sewing machine cuts the thread under the sewing material at the end of the sewing. The cut end of the stitch is pulled onto the sewing. Because of β, J〇«59 If the needle is dropped too much, or the needle and the needle are too small, the problem with the thread detector is caused. Specifically, when the upper (four)... passes through the _interval, the total deficiencies in the ankles are at 48 in Fig. 13. The location of 5 dials continued. . 1, the distance between the front end of the needle becomes very small, so that the - state cannot pass between the bur and the inner presser. Dialing line == problem, two methods were proposed. The first method is to make the car café "small and small, and it will not interfere with the dialing (four), so it is expected to be surely from (4). The first method of the dialer is used to raise the bur. That is, at the time of sewing, the drive motor that can be held by the needle bar holding the stylus is rotated in the reverse direction, and the stylus is raised to increase the distance between the stylus and the inner presser foot. Patent Document 1: Japanese Laid-Open Patent Publication No. Hei 9-253365. SUMMARY OF THE INVENTION The present invention discloses a problem to be solved by the invention. However, in the first method, the inner leg has a ring shape, and the needle and the wire penetrate the ring shape, so even Pulling the thread from the sewing thread with the threader will still pass through the (four) foot. Therefore, when the sewing of the next stitch is performed, as shown in Fig. 14, the inner presser foot 5G1 presses the wire 502 to which the bur is attached, so that the quality of the stitch is lowered. Also, in the second method, after the sewing is finished, the bur is raised, and as shown in Fig. 15, the balance of the scale 5 〇 3 applied to the stitch tension will hang on the 砰 503 and the rut 5 〇. 4 lines of 5 〇 5 loose him (as in the (4) two-point key line 6 not). Therefore, when the threader is actuated, the slack line 505 is pulled out from the bur 504 on the upper side of the stylus 504, and the line 505 cannot be surely picked out from the sew. Moreover, the wire 5〇5 pulled out from the needle tip also hinders the fixation of the sewing material. Further, as shown in Fig. 16, the wire 505 may be pulled up from the bur 504 because the wire 505 is pulled up by the rise of the scale 5 〇 3 at the beginning of the sewing (such as the two-point chain of Fig. 16). Line shown). Therefore, the present invention has been made to solve the above problems, and an object thereof is to provide a sewing machine which can reliably pull a wire from an inner presser by a threader without causing a bad influence on stitch quality or sewing workability. . Means for Solving the Problems In order to solve the above problems, the invention system of the invention of the third aspect of the patent application includes: an inner presser foot for pressing the sewing material when the bur is pulled out from the sewing object Needle plate; the threader can be used after sewing the end of the cutting line, 'wearing i« between the needle and the front _, and then pulling out the _ _ _ _ _ _ _ _ _ The above-mentioned shouting foot moves up and down with the front stylus and moves up and down; the driving control mechanism can control the _device to start the sewing of the final stitch until the front of the front slinger starts to lower the inner pressing foot To the predetermined height of the needle plate. π Here, the predetermined height means that the threader can pass the height of the inner presser foot between the aforementioned bur and the inner calendar foot relative to the needle plate. The invention of claim 2, wherein the driving control mechanism controls the driving device to cause the aforementioned driving device when the initial position of the inner pressing leg exceeds a reference height. The lowering and the aforementioned reference height (four) are such that the aforementioned threader can pass through the minimum spacing required between the aforementioned wheel 1356859 needle and the aforementioned inner presser foot. The invention of claim 3, wherein the driving control mechanism controls the driving device such that the inner pressing foot only drops a distance exceeding the reference height, and the reference The height is the minimum spacing required between the aforementioned stylus and the aforementioned inner presser. Effect of the invention

10 根據記載於申請專利範圍第1項之發明，於撥線器拉出 插進内壓腳的線時，可確實地穿過車針與内壓腳之間，而 不會如以往般讓内壓腳壓住線而使針跡品質低落，也不會 使通過車針的線鬆弛而無法把線從縫製物中拔出、卻反而 把線從車針中拔出。因此，本發明可不對針跡品質或縫製 作業性帶來壞影響，而可藉由撥線器確實地將線從内壓腳 中拉出。 15 對於記載於申請專利範圍第1項之發明，縫製終了後使10 According to the invention described in the first paragraph of the patent application, when the thread take-up device pulls out the thread inserted into the inner presser foot, it can surely pass between the bur and the inner presser foot without being allowed to pass inside. The presser foot presses the wire to make the stitch quality low, and the wire passing through the bur is not loosened, and the wire cannot be pulled out from the sewing object, but the wire is pulled out from the bur. Therefore, the present invention can not adversely affect the stitch quality or the sewing workability, and the wire can be surely pulled out from the inner presser by the threader. 15 For the invention described in item 1 of the scope of the patent application, after the sewing is finished,

前述内壓腳下降至前述預定高度時，可使下降至預定高度 途中之内壓腳不接觸到縫製中的縫製物，並可防止因為内 壓腳壓住縫製物而使縫製物品質低落。且，由於無須同時 進行縫製之控制及内壓腳下降至預定高度之控制，故可減 20 輕縫紉機控制部的負擔。 根據記載於申請專利範圍第1項之發明，開始縫製最終 針跡時前述内壓腳下降至前述預定高度之情況下，由於可 縮短内壓腳下降至預定高度之時間，故可縮短縫製週期。 根據記載於申請專利範圍第2項之發明，若内壓腳初期 8 較基準尚度更低的位置時，驅動裝置*會使内壓 腳下降，僅於必須形成可賴線”過車針㈣壓腳間之 間隔時才㈣内_，故可缩短縫製週期。 據己載於申δ月專利範圍第3項之發明，可讓内壓腳邊 下：以，撥線器可通過車針及内壓腳之間，同時維持其下 降量為最小限度。藉此可縮短内壓卿下降的時間，並可縮 短縫製週期。When the inner presser foot is lowered to the predetermined height, the presser foot can be prevented from coming into contact with the sewing material during sewing while being lowered to a predetermined height, and the quality of the sewing material can be prevented from being lowered due to the inner presser pressing the sewing material. Moreover, since it is not necessary to control the sewing at the same time and the internal presser foot is lowered to the predetermined height, the burden on the sewing machine control unit can be reduced. According to the invention of the first aspect of the patent application, when the inner presser foot is lowered to the predetermined height when the final stitch is started to be sewn, since the time during which the inner presser foot is lowered to the predetermined height can be shortened, the sewing cycle can be shortened. According to the invention described in the second paragraph of the patent application, if the initial pressure of the inner presser foot is lower than the reference degree, the driving device* will lower the inner presser foot, and only the detachable line must be formed. When the interval between the presser feet is only (4), the sewing cycle can be shortened. According to the invention of the third item in the patent scope of the application of the δ, the inner presser can be placed under the side: the dialer can pass the bur and The inner pressure foot is maintained at the same time while minimizing the amount of drop, thereby shortening the time for the inner pressure to fall and shortening the sewing cycle.

By shaking the rocker coupling 5, the rocking shaft 6 is also rocked, so that the other end of the first link 8 is used as the rocking fulcrum. The other end of the first link 8 is slightly perpendicular to the axis of the rocking shaft 6. (Crossing the 15th direction D3 of the in-line direction 〇2 of the third link 20 and the fourth link 22). The other end of the second link 11 is rocked in the in-line direction D2 of the third link 20 and the fourth link 22 as the other end of the first link 8 is rocked, and is coupled to the other end of the second link 11 The third link 20 and the fourth link 22 of the portion are swayed in the in-line direction (up-and-down direction) D2. The inner link of the fourth link 22 is connected as the third link 20 and the fourth link 22 are rocked. The 28 moves in the up-down direction D1 toward the lower side 20, so that the inner presser foot 29 also moves up and down. &lt;Operation of Pulling the Wire from the Inner Presser According to the Dialer Device&gt; Next, the operation of pulling the inserted inner presser 29 by the dialer device 200 will be described. As shown in Fig. 12, when the sewing of the sewing material is finished and the thread is cut (step 15 SI), the upper shaft 2 is stopped after the cutting line is stopped, and the driving of the yoke i and the inner pressing leg 29 is also stopped (step S2). Then, the CPU 301 compares the internal presser foot data and the reference height data after the sewing is completed by executing the drive control program 305a, and compares the sewing data 3〇4a' in the data area 3〇4 to determine the inner presser foot. Whether the height is higher than the reference height (for example, the height of the needle plate is 2 mm) (step S3). At this time, if the height of the inner presser foot is higher than the reference height (step magic: YES), the CPU 301 transmits a drive signal that can only lower the inner presser foot 29 by the distance between the inner presser foot height and the base level difference to the motor 42. Then, the motor 42 lowers the inner presser foot 29 according to the received drive signal (step S4). On the other hand, if the inner presser foot is lower than the reference height (step S3: NO), the CPU 301 does not apply to the motor 42. The drive signal is transmitted and the process proceeds to step 55. After the internal presser foot 29 is moved to the position of the reference height by the above method, the CPU 301 transmits a drive signal to the electromagnetic coil (step S5). The electromagnetic coil drives the connecting link 2〇1 based on the received driving signal, the rocking link 202 is rocked by the driving of the connecting link 2〇1, and the cam member 203 is rotated by the rocking of the rocking link 202. The shaft member 2〇4 is rotated by the rotation of the cam member 2〇3, and as the shaft member 204 rotates, the threader 205 moves with the base end portion as a center of rotation, so that the dial portion 2 formed at the front end portion The crucible 5a passes between the inner presser foot 29 and the bur 1 and pulls the suture T in a direction perpendicular to the vertical direction of the bur. Then, the thread T inserted into the inner presser foot 29 is pulled out by the amount of the threader 205 being moved by a predetermined amount or more. &lt;Functional effect of the embodiment&gt; According to the internal presser device 1 of the sewing machine of the embodiment, the CPU 301 executes the drive control program 3〇5a, and the motor 42 can lower the 1356859 inner presser 29 to the end after the sewing is completed. Base height. Thereby, the thread taker 205 pulls out the thread inserted into the inner presser foot 29, and can surely pass between the needle 1 and the inner presser 29 without pressing the line τ as the inner presser 2 9 as before. However, the quality of the stitch is lowered or the line τ passing through the needle i is slackened, and the thread cannot be pulled up from the sewing object, and the thread is pulled out from the needle 1 by the reverse 5 . Therefore, it is possible to have a bad influence on the stitch quality or the sewing machine ejector, and the thread ejector 205 surely pulls the thread out of the inner presser foot 29. Further, by changing the reference height, even if the thickness of the sewing material is changed, it can be easily matched. Since the inner pressing leg 29 is lowered to the reference door degree after the sewing is completed, the inner pressing leg 29 can be prevented from coming into contact with the sewing material during sewing, thereby preventing the inner pressing foot 29 from being pressed and sewn. The quality of the sewing material is low. Further, since it is not necessary to simultaneously control the sewing and control to lower the inner presser 29 to the reference height, the load on the control device 300 can be reduced. Further, since the CPU 301 executes the drive control program 3〇5a, the inner presser foot height of the inner presser foot 29 after the end of the sewing process exceeds the reference height, so that the dial 205 can be passed through the bur! When the minimum distance required between the inner leg 29 and the inner leg 29 is reached, the motor 42 lowers the inner presser 29, so that the motor 42 does not lower the inner presser 29 if the inner presser height is lower than the reference height. Thereby, since the dusting foot 29 can be driven only when it is necessary to form the spacing between the yoke and the inner pressing leg 29, the unnecessary movement of the inner leg 29 can be reduced, and The sewing cycle can be shortened, so the cost of sewing can be reduced. Further, since the CPU 301 executes the drive control program 3〇5a, the inner presser foot height of the inner presser foot 29 after the sewing is completed exceeds the reference height, so that the threader 205 can pass between the bur and the inner dust leg 29. At the minimum required interval, the J7 1356859 motor 42 can reduce the internal presser foot 29 by only a distance greater than the reference height, so that the inner presser foot 29 can be lowered to allow the dial 2 〇 5 to pass through the yoke The inner presser foot 29 can control the amount of the drop to a minimum. Thereby, since the time for lowering the inner presser foot 29 can be shortened and the sewing cycle can be shortened, the cost of the sewing machine 5 can be reduced. 10 15 20 Further, the present invention is not limited to the embodiment described. For example, the network drive control program may be configured such that the inner presser foot is lowered to the reference height when the final stitching of the motor is controlled. Thereby, it is possible to parallel with the final stitch and (4) the presser foot is lowered to the reference height. In this way, the time for lowering the internal calendar _ to the reference height can be shortened, and the __ can be shortened, so that the cost of sewing can be _. - In addition, the control of the motor by the drive control program is such that the internal pressure foot is down to the reference height, but it is lowered to a height lower than the reference height. Moreover, the period during which the inner presser is lowered is not limited to the end of the sewing and At the beginning of the final stitching of the sewing, it is also possible to start the sewing operation and the start of the sewing machine. (9) At the beginning of the stitching, the thread can be self-twisted, the driving mechanism of the electric pairing device, the number of connecting rods, etc. The base height at the time of descent, the type of sewing machine, or the size of the dialing line can be changed freely depending on the organization.
