That is, the driving of the stepping motor 42 is performed in accordance with the variable shaft 39 and the eccentric cam. %, the order of the movement joint portion % is transmitted, and then the movement joint portion 36 moves the guide member 34 〇 20, the bevel gear 43 is engaged with the bevel gear μ, so that the drive of the stepping motor can be output to the variable shaft 39. The direction of the axial direction is still orthogonal. The bearing material, the internal presser foot lifting cam 45, etc. are coaxially coupled with the bevel gear. The fourth figure is the inner presser foot lifting cam 45_ the surrounding structure from the center line 15 1363115 toward The operation explanatory diagram at the time of observation. As shown in Fig. 4, the inner presser foot lifting cam 45 is formed in a range of 0 to 180 degrees around the fulcrum, forming an arc having substantially the same distance from the center of rotation to the outer peripheral surface. In the shape (hereinafter referred to as the maintaining portion 45a), the distance from the center of the rotation 5 to the outer peripheral surface in the maintaining portion 45a is formed in the range of 180 to 360 degrees, and the distance from the center of the rotation to the outer peripheral surface is a shape that gradually becomes larger in a clockwise direction (hereinafter referred to as The inner presser foot lifting cam 45 is used for raising and lowering the inner presser foot 4 to the inner leg raising member 46 at the rear height position P5 after the sewing end is completed, and the outer peripheral surface of the inner presser foot lifting cam 45 The outer peripheral surface of the cylindrical drum 47 provided on the end portion 1 of the inner presser foot raising member is abutted. That is, when the maintaining portion 45a of the inner presser lift cam 45 abuts against the drum 47, the inner presser foot The rising member 牝 does not rise (see FIG. 4), but when the changing portion 45b of the inner presser lift cam 45 abuts against the drum 47, the inner presser rising member 46 rises. The inner presser rise member 46 The intermediate portion is attached to the slit 15 frame 15 by the pin 48 and is freely rotatable, and the other end of the inner presser foot riser member is disposed below the inner presser foot support 27. The inner presser foot is provided. When the change portion 45b of the lift cam abuts on the drum 47 and raises the other end of the inner presser riser member 46, the inner presser foot 27 can be raised, and the inner presser 29 can be raised to the rearward height position P5 (refer to 7)). In addition, the seam holder 15 is provided with a spring hanging portion 49 above the inner pressure 20-foot ascending member 46, and one end of the coil spring 5〇 is hung on the distal elastic lug portion 49 and the other end is hung in the inner pressure. The foot rises near the end of the member. Thereby, the end portion of the inner presser foot raising member 46 can be given a potential to be normally directed upward. As described above, the two-degree adjustment device is constituted by the corner 榫 33 to the coil spring 50 and 16 1363115. That is, the position of the bottom dead center of the C-clip 29 can be moved to an arbitrary height within the reciprocating movement of the motor 42, and the position of the inner_29 can be used during sewing by driving the remaining half-cycles. Switch between the retracted positions when not sewing. 5, the maintenance portion 45a and the roller 47 of the inner presser foot lifting cam 45 are described in detail.

接觸的半周分角度範圍内驅動步進馬達42時，設在可變軸 39前端的偏心凸輪38會透過移動連結部％搖動引導構件 34。結果，角榫33會在第1圖的左右方向上移動且更使第 3連結部20與第4連結部22從直線狀的排列狀態變化成在彼 10此的連結部彎曲的狀態。於是，第3連結部2〇與第4連結部 2 2的連結長度l依照彎曲量而產生長度變化，且最後會變更 調節内壓腳29的上下移動之下死點高度。 又，在内壓腳升降凸輪45的維持部45a與滾筒47接觸的 半周分角度範圍内，内壓腳上升構件46並不會發生搖動。When the stepping motor 42 is driven in the half-circumferential angle range of the contact, the eccentric cam 38 provided at the front end of the variable shaft 39 transmits the guiding member 34 through the moving joint portion %. As a result, the corners 33 move in the horizontal direction of the first drawing, and the third connecting portion 20 and the fourth connecting portion 22 are further changed from the linearly aligned state to the state in which the connecting portions are bent. Then, the length l of the connection between the third connecting portion 2〇 and the fourth connecting portion 2 2 changes in length in accordance with the amount of bending, and finally the height of the dead point below the vertical movement of the inner pressing leg 29 is changed. Further, in the half-circumferential angle range in which the maintaining portion 45a of the inner presser foot lifting cam 45 is in contact with the drum 47, the inner presser foot rising member 46 does not shake.

另一方面，在内壓腳升降凸輪45的變化部45b與滾筒47 接觸的其餘半周分角度範圍内驅動步進馬達42時，滾筒47 會逐漸被壓到下方，且内壓腳上升構件46的前端部會透過 内壓桿托腳27與内壓桿28使内壓腳29往上方移動。因此， 可使内壓腳29從使用位置提高到退後位置。又，要讓内壓 20 腳29從退後位置回到使用位置時，只要驅動步進馬達42使 滾筒47從内壓腳升降凸輪45的變化部45b移動到維持部 即可。藉此’可進行内壓腳29在使用位置與退後位置之門 的切換。 (夾線裝置) 17 夾線裝置65設有可依據通電流量產生推力之線張力電 “圈66及-對藉由線張力電磁線圈關閉其間隙間隔 4夹起上線以給予線張力之夾線盤。 線張力電㈣目⑽料_電路心與操作控制 ^置7〇連接。 藉由驅動電路66a以依據操作控制裝置赌出的控制 ^之電流值對線張力電磁_66進行通電，可輸出任意 • 推力’且可賦予上餘意張力。 (内壓腳感測器） 月）述内壓腳裝置1的第2連結部^中，係藉線圈彈箸 16對第1圖的左端部賦予彈性力朝向上方，且在右端部透過 第3連結部20對内壓聊29傳達上下移動力並藉由第i連結 部8賦予中間部上下移動力。又，限制構件19抵接於第罐 結部11的左端部上側，以限制其往上方移動，因此，縫製 15時只要線圈彈簧16的彈性力可使第2連結部u左端部維持 _ 核接於限制構件19之固定位置，即可使第2連結部u只以 左端部的有肩螺釘18為中心進行搖動。 然而，由於布料厚度比一般的厚等狀況而無法使内壓 腳29到達其預定下死點時’第2連結部u的右端部便不會下 2〇降，因此，會以該右端部為中心開始搖動且左端部下降移 動。即，第2連結部η可在内壓腳29下降時承受超過預定量 的負荷時，發揮作為釋壓構件之機能以進行釋壓動作來取 代内壓腳29的下降動作(左端部的下降移動）。 在剷述結構作為前提之下構成内屋腳感測器6〇。即， 18 1363115 内壓腳感測器60包含有設在第2連結部11左端部之第一接 點61，及從上方帶著些許彈性按壓力抵接於第一接點61之 切片狀的第二接點62，並以該等接點來構成接點式開關。 第一接點61係透過第2連結部11等構件而接地。又，第 5 一接點62可從通電電路60a通電，並在第一接點61與第二接 點62的接觸狀態下通電，而分開時則會斷電。On the other hand, when the stepping motor 42 is driven within the remaining half-circumferential angle range in which the varying portion 45b of the inner presser foot lifting cam 45 is in contact with the drum 47, the drum 47 is gradually pressed downward, and the inner presser foot rising member 46 is The front end portion moves the inner presser foot 29 upward by the inner presser foot 27 and the inner presser 28. Therefore, the inner presser foot 29 can be raised from the use position to the retracted position. Further, when the internal pressure 20 leg 29 is returned from the retracted position to the use position, the stepping motor 42 is driven to move the drum 47 from the changing portion 45b of the inner presser foot lifting cam 45 to the holding portion. Thereby, the switching of the inner presser foot 29 at the door of the use position and the retracted position can be performed. (Clamping device) 17 The wire clamping device 65 is provided with a wire tension electric "power coil" which can generate a thrust according to the energizing flow rate, and a wire clamping plate for holding the wire tension by closing the gap interval 4 by the wire tension electromagnetic coil. Wire tension electric (4) mesh (10) material_circuit core and operation control ^7〇 connection. The drive line 66a energizes the line tension electromagnetic_66 according to the current value of the control gambling according to the operation control device, and can output any • Thrust' and the upper end tension can be given. (Internal pressure foot sensor) The second connection part of the inner presser device 1 is elasticized by the coil magazine 16 to the left end of the first figure. The force is directed upward, and the vertical force is transmitted to the internal pressure chatter 29 through the third connecting portion 20 at the right end portion, and the intermediate portion is vertically moved by the i-th connecting portion 8. Further, the restricting member 19 abuts against the canned portion The upper end of the left end portion of the elliptical portion 11 is restricted from moving upward. Therefore, when the sewing force 15 is performed, the elastic force of the coil spring 16 can maintain the left end portion of the second connecting portion u to be fixed to the fixed position of the restricting member 19. 2 joint portion u only with the shoulder screw 18 at the left end The heart is shaken. However, when the inner presser foot 29 cannot reach the predetermined bottom dead center due to the thickness of the cloth being thicker than usual, the right end portion of the second joint portion u will not fall by 2 ,, so When the right end portion is centered, the left end portion is moved downward, that is, when the second press portion η is subjected to a load exceeding a predetermined amount when the inner presser foot 29 is lowered, the function as a pressure releasing member is exerted to perform a pressure releasing operation. The lowering operation of the inner presser foot 29 (the downward movement of the left end portion) constitutes the inner leg sensor 6〇 on the premise of the scribing structure. That is, the 18 1363115 inner presser foot sensor 60 is included in the second The first contact 61 of the left end of the connecting portion 11 and the second contact 62 of the slice-shaped contact point of the first contact 61 with a slight elastic pressing force from above, and the contact type is formed by the contacts The first contact 61 is grounded through a member such as the second connecting portion 11. Further, the fifth contact 62 can be energized from the energizing circuit 60a and in contact with the first contact 61 and the second contact 62. Power down, and power off when disconnected.

Further, the sewing machine motor 81 is a servo motor, and its drive control is performed in accordance with the amount of rotation of the control signal of the operation control device 70 by the drive circuit 81a. Further, the rotation amount is controlled based on the usable angle unit, so that the operation control device 70 can know the current rotation angle position of the sewing machine motor 81. Further, the stepping motor 42 of the inner presser device 1 is connected to the operation control device 70 via the drive circuit 42a, and its drive control is performed in accordance with the amount of rotation of the control signal No. 115 of the operation control device 7A. Further, as described above, the wire tension magnet wire of the wire clamping device 65 is connected to the operation control device 7A via the drive circuit 66a, and the wire tension is controlled in accordance with the control signal of the operation control device 70. 5 #作控制装置7〇Includes: After writing the executable machine, the control program and control data of the various functions, r〇m72 '· according to the control program set and the operation of each part After the data is displayed, the microcomputer-CPU 71 of the display unit 75 is displayed; the data of the CPU 71 and the various materials related to the sewing process can be stored in the RAM 73 of the work area; and the processing data stored in the RAM 73 can be recorded and saved. Or store EEpr〇m74 for sewing data for pre-quilting. Further, the RAM 73 is provided with various working memories, calculators, and the like, and is also used as a work area at the time of sewing operation. As described above, the EEPROM 74 can memorize the sewing data of various parameters which are useful for sewing. In other words, in the sewing data, the driving amount of the y-axis and the γ-axis motors 82 and 83 for positioning the number of needles (the number of times the needle is moved up and down) on the cloth corresponding to the styling from the sewing is performed in accordance with the sewing. The number of needles is set every time after the start, and the tension data of the wire tension solenoid 66 at the time of general sewing is also set. The CPU 71 controls by executing a predetermined processing program to drive the X-axis and γ-axis motors 82 and 83 in advance according to the sewing data at the time of the lower stitching according to the sewing data at the time of sewing, so that each lower needle is driven. Follow the set order and at the set position. Thereby, (^1171 can be used as the control of the sewing 21 uojin control device. Furthermore, mm is selected by the predetermined processing program, and by the pull type of the operation 75, the following mold handle is selected to select the recording processing. When the thickness of the cloth is measured in the straw during the sewing process, the thickness variation of any number of needles in the sewing data is added to the thickness of the sewing machine = the thickness acquisition mode during sewing; and the feeling of the inner pressure when not sewing Measure _ After measuring the thickness of the cloth, 'will change the thickness of the needle on any needle that is sewed, and add the thickness of the sewed material to the non-sewing thickness of the stencil. 10 ♦ When selecting the thickness acquisition mode during the sewing operation, The coffee 71 is controlled by the predetermined processing program and according to the sewing data in the EEPR〇M74, and the operation control is performed for each movement needle, the dad mechanism, and the cloth holding mechanism according to each movement needle, and the internal pressure is controlled by the internal pressure. The foot sensor miscellaneous measurement of the mother phase of the fabric thickness is thick. That is, the mm can be used to machine the number of needles, and the internal pressure foot sensor is detected. , 62 when the cut state (cloth thickness) Increased production), : The number of needles in the field is temporarily stored in the RAM73, and at the end of the sewing, the ; first-variable needle number detection (4) device will produce the increase in the thickness of the cloth: (4) as the cloth thickness data plus the writer Sewing data processing. 2〇a _ 士, The thickness acquisition mode for non-sewing is to set the fabric in the cloth holding mechanism and hold the lever without setting the bur or the car line in advance. When the thickness setting mode is selected, the CPU 71 performs the operation of the positional movement of the machine in accordance with the sewing process in the EEPROM 74 by the predetermined processing program (4), and borrows the _ number to make the cloth. Towards each material (4), and __ system (4) number of needles = material thickness change. That is, coffee 71 can calculate the number of needles according to 5 10 15 20 : 2 6 6 勒, and detect _ foot sensor 6. Each contact 6 b 62 mail reading material (the degree of deployment is increased (4), the number of needles at the time of production is temporarily stored in RAM73, and at the end of (4), the needle is measured and controlled. The number of needles is treated as the material thickness of the cloth plus the sewing data of the person Further, after the cloth thickness data is added to the sewing material in the non-sewing thickness acquisition mode, the CPU 71 executes the sewing mechanism for the cloth holding mechanism in accordance with the new sewing data in the E"EPR0M74 by a predetermined processing program. The operation control of moving the cloth toward each position, and measuring the number of needles for each thickness change according to the thickness information of the root fabric, driving the stepping motor 42 of the internal pressure device 1 to perform height adjustment, and performing confirmation operation control The device accepts the change of the height of the height of the section by the operation panel 75. Further, in the any-mode, once the cpU71 detects the joints 61, 62 by the predetermined processing program and by the internal presser foot sensing (4) The off state a ~ 1 is regarded as the increase in the thickness of the cloth already produced, and the operation of the presser foot height control means for raising the inner presser foot 29 by a predetermined one is performed for the v feed motor 42 of the inner presser foot. Further, the amount of rise of the inner presser 29, i.e., the drive of the stepping motor 42, can be stored in the ROM 72 as an initial data in advance, or stored in the EEpR 〇 M74 in association with the sewing data. Further, at the time of sewing, when the CPU 71 detects the disconnection state of each of the contacts 61' 62 by the predetermined processing program and by the internal presser foot sensor 6, 23 1363115 can be regarded as an increase in the thickness of the cloth which has been produced. The wire tension solenoid 66 of the wire clamping device 65 is controlled to operate the thread tension control device to change the thread tension. Further, as for the value to be changed of the wire tension, it is preferable to store the amount of energization to the wire tension solenoid 圏 66 in advance to be stored in R 〇 M72 or 3 EEPRQM 74 so that the tension increases in accordance with the increase in the thickness of the cloth. (Operation of Sewing Machine) The sewing operation based on the sewing machine 1〇0 for controlling the aforementioned operation control device 70 will be described based on the flowcharts shown in Figs. 7 to 9 . Fig. 7 is a flow chart showing the processing of the operation control device 70 at the time of initial sewing when the setting of the thickness acquisition mode is performed in the above-described sewing. First, after the sewing machine motor 81 is driven to start sewing (step si), the CPU 71 detects whether the internal presser foot sensor 6 is in the 〇 ff state (the state in which the first contact 61 and the second contact 62 are separated) (step S2). 15 The result shows that when the power supply circuit is in the on state (the state in which the first contact 61 is in contact with the second contact 62) (step S2: N〇), the number of the needles is calculated by referring to the encoder of the slot machine motor 81. The needle counter is used to determine whether or not the final number of stitches to be performed in the series sewing set to the sewing data is reached (step s3). Then, 'when the final number of needles is reached (step S3: YES), and 20 has memorized the number of needles for raising the inner presser foot μ in steps S4 and S8 or the number of needles returning to the original height, 'perform the same The number of needles, the amount of increase in #, and the number of needles that continue to rise are added to the processing of the sewing data (step (10), and the sewing is finished. When the number of final needles is not reached (step magic: N〇), return to step 24 The tr is used to determine whether or not the number of needles for increasing the thickness of the material produced by the thickness of the cloth material in the sewing material is increased, and the number of needles for increasing the thickness of the cloth is increased (step S15). ^ After the number of needles is not the number of needles According to the sewing data, the sewing is performed (step S15: NO), and when it is the number of the needles (step S15. YES), the process moves to step si6. 10 In the step of the 6th towel, the lining is a needle for increasing the thickness of the cloth. The number is increased from the back to the count of the thickness of the county surface, and when _ is the number of needles for which the thickness of the cloth is increased (step S16: YES), the c_ drive controls the stepping motor 42 to raise the bottom dead center of the inner presser 29 The height set in advance (step S17), and the thread tension is executed The magnetic wire is energized (4) to form a wire tension when the thick cloth is set in advance (step S18). Then, the process proceeds to step S2. Further, it is judged that the thickness of the cloth is increased back to the thickness of the original cloth. When the time (step S16: N0), the CPU 71 drives and controls the stepping motor 42 to return the bottom dead center of the inner presser 29 from the rising position to the original height, and returns the line tension to the normal value (step S19), and moves to the step. Next, in step S20, the CPU 7i refers to the number-of-counter counter to determine whether or not the number of final needles 20 for a series of sewings set to the sewing data is reached, and the result is that the final number of needles is reached (step S20: yEs). When the 妗 bundle is sewed, and it is not reached (step S2 〇: N 〇), the process returns to the step S15 and the sewing is continued. The ninth figure shows that the actual operation is not performed even when the fabric is set to operate the respective parts. In the above-mentioned non-sewing thickness acquisition mode selection 27 1363115, the sewing machine motor 81, the cloth holding mechanism, and the inner presser device 1 are driven again, and the process returns to step S40. In the case of a few, the process proceeds to step S45 (step S44. YES) and the CPU 71 executes the process of adding the corrected amount of rise set in step S43 to the process of sewing the sewing data in the EEPROM 74 and ends the series of processes - again, from the figure 9 The sew material which is updated in the thickness-acquisition mode at the time of non-sewing is also sewed according to the flowchart of Fig. 8. The φ (effect of the embodiment) is permeable to the sewing machine 100. The inner presser foot 29 detects the change in the thickness of the cloth 1'. Therefore, it is not necessary to provide a separate member for detecting the thickness: the number of parts is reduced, and the space around the needle can be saved by the reduction in the number of parts', making the device compact and simple. To improve the overall productivity of the device. Further, when the thickness change is detected by the inner presser foot sensor 60, the control device 70 can be adjusted to adjust the bottom dead center height of the inner presser foot 29, so that the fabric can be guaranteed to be 15 and suppressed from being pressed when the inner presser foot 29 is lowered. The cloth can be used to accurately detect the object to be sewn 20 in the state of the influence of the foot. The thickness of the fabric can be obtained by the operation control device 7G. The number of needles for changing the thickness of the fabric = force: Write 'sewing data. Therefore, when sewing is performed after the data is obtained, it is known which thickness of the broken fabric is changed at the number of needles, and can be changed according to the thickness (four) control (four) line Device (4) The height of the bottom dead center of the foot device 1 can improve the quality of the seam product. In particular, in the thickness acquisition mode at the time of sewing, the thickness of the cloth is industrially efficient at the same time as the actual sewing production. The data is added to the sewing data so that the sewing system can be improved =: 2::=; the mode 1 is in the actual industry, and the seam making of the changing silk cyclist is quite a matter of the seam quality of the fabric. Adding = system ί: system: the opportunity in the thickness acquisition mode 'the height of the material thickness of the cloth, so the bottom dead point of the inner pressure foot is corrected. 10 - Step::, can make more correct sewing and sewing during sewing [Implementation 2] (Probable content of the implementation type)

The sewing machine is difficult to be different from the slitting machine (10), and the second connecting portion U is newly provided. - The end of the contact 61 is moved up and down, and the (four) foot sensor 6GA of the S is changed, whereby the thickness variation of the thickness of the cloth can be determined and the operation control of the thickness variation # can be performed. In the structure other than the processing content of ', ^ 2〇w money control, only the internal pressure foot sensing piracy 60A is different from the sewing machine j ,, therefore, the sewing machine i 〇〇a is the same as the sewing machine brain The structure is attached with the same component symbols and is only described for different points. The inner presser foot sensing H6GA includes a first contact 61 and a younger contact 62 for detecting a change in the thickness of the rib; and an end portion of the second joint portion 11 on the side of the first contact 61 is detected. The comb-shaped detecting member 63; and the optical-type tooth sensor 64 that can detect the number of comb teeth of the detecting member 63. The detected member 63 is fixedly attached to the first 5-contact 61 of the second connecting portion 丨i The comb teeth arranged at equal intervals are arranged in the up and down direction. The tooth number sensor 64 has an illuminating light source disposed behind the comb teeth of the detected member 63, and a light receiving element capable of detecting the brightness of the light source blocked by the comb teeth, and can receive light according to the up and down movement of the comb teeth The number of times of light and dark to detect the amount of movement up and down. Further, the detection signal of the tooth number sensor 64 is output to the operation control device 70. Further, although the tooth number sensor 64 is optical, the first contact 61 side of the second connecting portion 11 can be obtained. Any type of detecting element or sensor can also be used if the end is moved up and down. The control system of the sewing machine 100A described above is different from the sewing machine 100 described above in that the upper sensor count sensor is connected to the operation control device 70, and its detection signal is output. Further, unlike the initial sewing machine, when the processing 20 of the first or second change stitch number detecting control device is executed according to a predetermined processing program, the sewing machine is driven in accordance with the sewing data. Moreover, even when the thickness of the cloth changes, the thickness variation is detected, and the correlation between the thickness of the cloth and the number of needles at that time is given, and the thickness of the cloth is measured and written into the sewing data. Further, unlike the sewing machine 100, in the case where (10) Kawasaki performs the processing of the presser foot height control device according to a predetermined processing program, the 32 1363115 internal presser foot sensor 60 measures each connection. When the point 6 is cut off and the thickness of the cloth is measured by the tooth number sensor 64, the stepping motor π that controls the inner presser device i is operated to raise the inner presser foot 29 in accordance with the thickness of the measured cloth. Based on the foregoing points, the respective operations of the apparatus 70 according to the operation of the sewing machine 100A will be described below. (Operation of Sewing Machine) The following processing is performed in accordance with the control program for the execution of each processing in accordance with cpu7 of the operation control device 7Q. The axis of Fig. 11 shows a flow chart of the processing of the operation control device 7 when the initial sewing is performed, when the setting of the thickness acquisition mode is set to _). When the sewing machine motor 81 is driven to start sewing (step S51), the CPU 71 performs the movement of the teeth (four) of the ribs (four) (four) to determine whether the detected member 63 is moving up and down (step S52). Further, in the step S52 and the determination of whether or not the tooth number sensor of the step described later detects the vertical movement of the detected member 63, it is preferable to set the output of the slit machine motor 81 by the encoder or the like. The angle of rotation of the shaft or the upper shaft, and the angle formed by the inner presser foot 29 at the bottom dead center or before the bottom dead center, is performed. In the processing of the step, when the tooth number sensor 64 of the inner presser foot sensor detects the up and down movement of the detected member 63 (step S52: YES), the calculation of the tooth number is started. The number of moving teeth of the device 64 (step S53). Then, the CPU 71 detects whether or not the two contacts 61, 62 of the internal presser foot sensor 6A are in. In the hybrid state (step S54), and repeating the detection until the measurement of 〇ff 33 1363115-like cancer is performed, and after the measurement, the amount of rise of the inner presser foot 29, that is, the thickness of the cloth, is calculated from the calculated value of the number of moving teeth of the tooth number sensor 64. And then remembered in the RAM 73 (step S55). Next, the CPU 71 refers to the number-of-counter counter to temporarily record the current number of needles on the RaM 73 (step S56), and performs energization control of the wire tension solenoid 66 to form a thread tension which is set in advance for sewing a thick cloth ( Steps • S57). Further, the CpU 71 performs drive control of the stepping motor 42, and raises the bottom dead center of the inner presser 29 to the height of the fabric of the cloth thickness determined in step S55 (step S58). Then, the process of step S59 is continued, and the sewing is continued with the number of previously set needles rising at the bottom dead center of the inner presser foot 29. When the number of times has not been reached in the process of step S59 (step S59: NO) ', the process of step S59 is only repeated, but the process of step S63 described later in U may be referred to, and the number of counters may be referred to and finally arrived. When the number of needles is fixed, the sewing is finished, and when it is not reached, the processing returns to step S59. Next, at the bottom dead center of the inner presser foot 29, the number of the set stitches is increased: 1 when sewing is performed (step S59: YES), the coffee 71 will drive and control the stepping motor 42 (four) - 29 nail listening _ county height (step Lion 0), and 20 performs energization control of the wire tension solenoid 66 to return to the wire tension originally set to the sewing material (step S61). If it is determined again that the number of teeth of the internal pressure sensor 64 is detected, the up and down movement of the detected member 63 is detected (stepwise and the up and down movement of the detected structure (10) is detected (step S62: yes), then 34 is still When the portion of the cloth is thicker, the process from step S53 is performed again. Further, when the tooth number sensor 64 of the inner presser foot sensor 60A does not detect the vertical movement of the remaining member 63 (step S62: NO) means that the portion having the thickness of the cloth is 5, and therefore, the number of stitches is determined by referring to the stitch counter to determine whether or not the final stitch is set in a series of sewings set to the sewing data (step S63). Then, when the final number of stitches is reached (YES in step S6L), the number of needles for raising the inner presser foot 29 or the number of needles returned to the original height stored in step S56, the amount of lift stored in step S56, and the number of needles that continue to rise are added to the sewing machine. After the processing of the data (step S64), the sewing is finished. When the final number of stitches has not been reached (step S63: N〇), the process returns to step S52 and the sewing is continued. Further, the feeling of the presser is determined in step S52. Lion Sense (10) Whether or not the movement of the detected member 63 is detected, and when the tooth number sensing _ 15 does not detect the movement (step S52: N0), the needle number counter is referred to determine whether or not a series of sewing set to the sewing material is reached. The number of needles is finally transferred (step S65). Then, when the final number of needles is reached (step milk: qing, the writing of step S64 is performed until the sewing data is finished, and the sewing is finished, and when it is not reached (step S65: NO), the steps are returned. Processing of S52. Fig. 2 is a flowchart showing the processing of the operation control panel 70 when the second and subsequent sewings are performed in the selection setting of the thickness acquisition mode at the time of sewing. The number of needles for calculating the number of needles in the stone machine first drives the sewing machine motor 81 S71), and refers to the number 35 α of the sewing machine motor 81 to determine whether the thickness of the cloth is increased as indicated by the cloth thickness data in the sewing data. The number, or the number of needles to be fed back to the county, is increased (step S72). Then, when it is not the number of the aforementioned needles, it is sequentially sewn according to the sewing data (step S72: NO), and is in any When the number of needles is transferred (step S72: YES), the process proceeds to step 573. In step SB, it is determined that the number of needles for which the thickness of the cloth is increased or the number of needles for increasing the thickness of the original cloth is increased, and it is determined that the thickness of the cloth is generated. When the number of needles is increased (step S73: YES), cpim performs the drive control of the stepping motor 42 so that the bottom dead center of the inner presser foot 29 rises only by the number of needles measured by the inner foot sensor. The height of the cloth thickness increase amount (step S74), and the energization control of the wire tension solenoid is performed to form a wire tension set when the thick cloth is sewn (step S75). Then, the process proceeds to step S77. / 15 X ' is judged to increase the thickness of the cloth from the original cloth thickness (step S73: NOVCPim drive controls the stepping motor 42 to return the bottom dead center of the internal waste foot 29 from the rising position to the original height, and makes the thread tension After returning to the normal value (step S76), the process proceeds to step 577. Next, in step S77, the CPU 71 refers to the pin count counter to determine whether or not the final number of stitches for a series of sewings set to the sewing material is 20, and As a result, when the final number of needles is reached (step S77··yes), the sewing is finished, and when it is not reached (step S77··NO), the processing returns to step s?2 and the sewing is continued. Fig. 13 is shown in In the state in which the various parts are operated, the operation of the operation control device 70 is performed when the thickness is not selected for the non-sewing in the state of the operation of the part 36 1363115. The processing of the operation control device 70 is started. First, the sewing machine motor 81 starts driving, and cpU71 performs It is judged whether or not the tooth number sensor 64 of the internal presser foot sensor 60A detects the up and down movement of the detected member Μ, 5 (step S81). • X, whether the tooth number sensor 64 of the step S81 is checked. The upward movement of the member to be detected 63 is preferably set such that the rotation angle of the output shaft or the upper shaft of the sewing motor 81 is detected by an encoder or the like, and the inner pressing leg 29 is at the bottom dead center or below. When the angle formed before the dead point is executed, 1 〇 'then', in the processing of the step, when the internal presser foot sensor records the up and down movement of the detected member 63 (step S81: YES), cpu7im starts calculation. The number of moving teeth of the tooth number sensor 64 (step S82) Next, the CPU 71 detects whether the two contacts 61, 62 of the inner presser sensor ship are in the ❶ ff state (step S83), and repeats the detection until the beating is detected. In the 15th state, the number of moving teeth of the tooth number sensor 64 is measured after the measurement. • The amount of rise of the inner presser 29, that is, the thickness of the cloth, is calculated by the calculation value, and is stored in the RAM 73 (step S84). The number-of-counter counter temporarily stores the current number of needles in the RAM 73 (step S85). Then, the CPU 71 refers to the needle count counter to determine whether or not the final number of stitches for setting a series of stitching of the stitching data is reached (step S86). Not reaching the most When the number of stitches is finalized (step S86: N〇), the process returns to step S81. Further, when the final number of stitches is reached (step S8 & YES), the sewing machine motor 81 is stopped (step S87), and the process is executed. The %5 memory is increased in the thickness of the fabric by 37 ΓΓΓί, and the degree of the stitching is increased as the sewing data of the cloth erb-2m and the EEPR0M74* is written (step S88). The result of the determination of the step S81 is the internal pressure.
