The technical field of the invention is 3 [0001] The present invention relates to having a line cutting The mechanism, a presser lift mechanism 5, and a sewing machine for the one-line moving mechanism.

C U

[0002] In recent years, the sewing machine on the market has been provided with a line cutting mechanism for cutting the suture immediately after the sewing work is finished, and a pressing 10 of the pressing device is raised as a 'lifting mechanism and a moving mechanism for moving the needle thread. [0003] In such a conventional sewing machine, a drive unit for driving a wire moving mechanism, a wire cutting mechanism, and a pusher lifting mechanism are separately provided. Therefore, this kind of machine is very complicated and the number of parts is large, so the sewing machine becomes 10 to 15 weights and the size is very large. The staff who use the sewing machine in the factory are mainly women. It is very laborious for the staff to operate such a bulky machine and must have a wide sewing space. Therefore, the output is very limited. [0004] In a sewing machine, a recirculating sewing machine also includes this mechanism. Using this cycle 20, the sewing machine forms another loop stitch without interruption after the formation of the loop stitch. When a four-hole button is sewn on the stuart, a stitch is formed through two of the four holes. Cut the line to prevent any horizontal stitches from being left behind. Thereafter, a slit, a spring, is formed through the other two holes. In this case, after the first two holes are formed by the % stitches, and the loop stitches of the other two stitches are formed, 1299763 玖, the invention description is preferred, and the sewing work is preferably performed without continuously lifting the cloth. Executed under the condition of the device. [0005] When it is preferable that the transverse suture is not formed between the first loop suture and the loop suture which is attached, the thread cutting operation and the line moving operation are performed after the first suture is formed. The inventors of the present invention have applied for an invention relating to a sewing machine in which a wire cutting mechanism and a presser lifting mechanism are operated by the same driving device. However, in this sewing machine, when the wire cutting operation and the wire moving operation are performed after the first stitch is formed, the presser lifting mechanism is interconnected therewith. As a result, the press device is released, causing the cloth to slide away from its position. Therefore, the starting position of the next stitch is moved from its desired position. [0007] 15 Especially in a sewing machine in which a cloth pressing device presses a cloth while grasping a button, the cloth and the button are lifted when the presser moves upward. Therefore, when the press device moves downward, the cloth can be pressed, but the button will be removed from its position, or the cloth will be folded up. Result 'The needle may break when the stitch is formed. SUMMARY OF THE INVENTION [0008] An object of the present invention is to provide a sewing machine having a wire cutting mechanism, a pusher lifting mechanism, and a one-line moving mechanism, wherein the number of parts is reduced, so that the weight and size of the sewing machine are lowered. Another object of the present invention is to make the quality of the work piece changeable according to the need to suppress the presser lift mechanism 1299763 发明, the invention description, to solve the problem of the sewing work, and the work can be completed efficiently. Another object of the present invention is to shorten the sewing process regardless of the sewing condition to improve work efficiency. [0009] Resolving the above problems, according to the first configuration of the present invention, such as the i-th diagram, the 2A to 2C diagrams, the 3rd to 7th diagrams, the 8th to 8th diagrams, the 9th to 9th diagrams, and the 1st As shown in FIG. 1C, the present preparation-sewing machine γ includes a linear cutting mechanism (10) having a movable knife that cuts a thread including a needle thread passing through the needle under the workpiece to lift one The cleaning device (7)) is a presser lifting mechanism (3〇) for pressing the working piece from the upper hunting, and has a threading path for moving across the needle and the workpiece and lifting by wire cutting a thread-moving mechanism for cutting a needle thread to a moving piece (slider arm 58) on the workpiece, wherein the sewing machine further comprises a single-drive 15 motor (pulse motor 80), a first cam (61) The cam is rotatably interconnected with the drive motor and has a linear cam portion (X2) for operating the wire cutting mechanism due to a change in rotational phase; a second cam (62) rotatably interconnected with the drive motor And having a change in the rotational phase of a predetermined phase different from the first cam a moving movement of the moving mechanism 20 wheel portion, and a presser lifts the cam portion (Y2), the cam portion operates the presser to raise the cam mechanism due to the change of the rotational phase; a first connecting element (line cut Wulian a cup 11) configured to connect the wire cutting cam portion and the wire cutting mechanism of the first cam; and a second connecting member (pressor lifting lever 3i) configured to respectively connect the wire moving cam portion and the second cam pressing Lifting the protrusion 63 12997 玖, the invention description wheel and the (4) lifting mechanism; and wherein the predetermined phase difference between the first cam and the second cam is set such that the line moving mechanism and the device lifting mechanism are online cutting mechanism due to The rotation of the drive motor is started after the end of the wire cutting operation. [0010] With the first configuration of the present invention, the wire cutting mechanism, the (four) device lifting mechanism, and the wire moving mechanism can be driven by a single drive motor. Therefore, the number of pieces of love is reduced, so that the weight of the sewing machine is reduced from the size of the Lihan to the Lie, and the sewing machine can be reduced in smuggling and the work efficiency is improved. [0011] Further, the wire cutting mechanism, the pusher lifting mechanism, and the wire moving mechanism can be started at a fixed time. The difference between the time when the chain B cuts the line and the time when the line is moved and the start of the presser lift can be fixed. Therefore, the delay of the cycle time can be avoided. [0012] According to the second structure of the present invention, in the slitting machine having the second structure, the driving motor can be rotated back and forth; and the wire cutting cam portion of the first cam and the pressing of the line=cam portion and the second cam The dust lifter cam portions are respectively symmetrical, and the table cutting mechanism, the wire moving mechanism, and the pusher lift mechanism have a _ fixed operation regardless of the rotational direction of the drive motor. [0013] :: Kang Ben: the second configuration of the Ming, the wire-cutting cam portion of the first cam is symmetrical with the door-lifting cam portion of the second arm of the second-hand cam Cutting mechanism, wire moving mechanism, and pusher lifting mechanism 9 1299763 发明 The invention has a fixed operation regardless of the direction of rotation of the driving motor. Therefore, 5, when the drive motor is forward or backward, the fixed line cutting operation can be performed, and the fixed line movement can be selected as the presser lifting operation of the twisting and fixing. Therefore, a smooth sewing work can be achieved. In addition, the Bu/, this configuration can be selected after the online cutting operation can be performed only in the mode in which the line movement operation is performed and the line movement operation and the money transfer operation operation (4) are performed after the operation is not performed. A pattern. [0014] According to a third configuration of the present invention, as in the drawings from 8c, n, 12 and 10, the sewing machine having the first configuration - the cam (6) and the second cam (4) are configured to include - a dead zone that blocks the wire cutting mechanism (10), the wire moving mechanism (50), and the presser lift mechanism (10); and the trigger machine further includes a control device (CPU 90) that can rotate the drive motor in a rotational direction, Continuously sequentially starting the first mode of the wire cutting mechanism, the wire moving mechanism and the presser 5 lifting mechanism, and rotating in the _ rotational direction to successively start the second mode change between the wire cutting mechanism and the wire moving mechanism, and then Conversely; the drive direction rotates the drive motor to move the rotational position of the drive motor to the dead zone before the pusher lift mechanism is activated. [0015]

According to the third configuration of the present invention, a control device is provided for rotating the driving motor in the direction of the ♦ to successively start the first mode of the wire cutting mechanism, the wire moving mechanism and the presser lifting mechanism, and Rotating in the direction of rotation to successively activate the second mode of the starting line (4) mechanism and the line moving mechanism, and then rotating the driving motor in a direction opposite to the direction of rotation, moving in front of the starting press lift mechanism by 10 1299763 玖, invention instructions Drive the rotational position of the motor to the dead zone. Therefore, accurate sewing work can be performed depending on different conditions. [0016] For example, if a 4-hole button is to be sewn on the cloth, and no horizontal 5 stitches are left. In this case, even when the cloth is supported and the lifting device is lifted up and the sewing operation is continuously performed, the problem that the cloth slips off when the cloth pressing device is lifted by the start of the pressing device lifting mechanism does not occur. Therefore, the sewing machine = can be completed efficiently. [0017] Further, when it is not desired to form a transverse stitch between the first stitch and the succeeding stitch for the sake of aesthetics, the sewing can be performed in the following manner. First, the first control mode is established by the control device to form a first suture. Then, the wire cutting operation and the wire moving operation are performed under the condition that the operation of the presser lifting mechanism is prevented. Next, after the formation of the next stitch, the first control device is established with the control device. Therefore, the press device is finally lifted up to complete the sewing work. In this way, no transverse stitching is formed between the first stitch and the next stitch. Therefore, it is possible to efficiently perform the sewing work with quality. [0018] 20 According to a fourth configuration of the present invention, the slitting machine having the third configuration further comprises: a movable area changing device (CPU 9) for moving the mechanism in the second control mode A movable area of the line moving piece (slider arm 58) of the line moving mechanism (5 〇) is changed at the time of starting.

Therefore, the movable area 5 of the wire moving piece can be appropriately set depending on the thickness of the cloth to be sewn or the like. Therefore, the swing of the moving piece of the wire can be prevented under a wide range of conditions. Therefore, the time required for the oscillating line to move the sheet can be shortened to improve the sewing efficiency. According to the fifth to seventh configurations of the present invention, the sewing machine can be configured in a configuration of simple, small size, and light weight. 10 [Embodiment] [0020] An embodiment of the present invention will be described below with reference to the drawings. [0021] In this embodiment, a one-piece slit machine in which one of the zipper stitches is formed by the fastener stitching will be described.

Further, Figs. 9A to 9C and Figs. 1A to (4) mainly show plan views of the cam member 6A to explain the wire cutting operation and the pusher lifting operation. [0025] First, the configuration of the wire cutting mechanism W will be described. The wire cutting mechanism 10 is constituted by a wire cutting link 11, a wire cutting connecting rod 13, a fixed blade 14, a movable blade 15, and the like. The wire cutting link 11 as the first connecting member forms a slightly half-bent 13 1299763 玖, and the invention describes a thin and long rod-like shape. A mating pin 11a (to be described later) that matches one of the cam grooves 61a of the first cam 61 of the cam member 60 is provided on the upper end portion of the wire cutting link u as shown in Figs. 9A to 9C. The wire cutting link 11 can be rotatably coupled to a machine frame not shown by a support portion 12 with its curved portion Ub. The lower end portion llc of the wire cutting link 11 is rotatably connected to the rear end portion of a mating flat plate 16 and the wire cutting connecting rod 13 by a screw 17 . A light blocking member 18 having a visor 18a is fixed to the end of the mounting plate 16. On the other hand, a light jammer 19 is fixed to the vicinity of the shading member 18 - the machine frame is not displayed. The light jammer 19 is used to measure the original position of the wire cutting mechanism ι. The photointerferer 19 is designed to output a signal indicating the line cutting mechanism 10 at its original position to the control circuit when the visor is positioned between the light emitting device and the light receiving device of the optical interferer 19. [0028] The wire cutting connecting rod Π is a long and thin rod-like member which is gradually bent upward at a pre-position such that its front end portion 13a reaches the bottom side of a needle flat plate. As shown in Figs. 2A to 2C, the movable negative connecting member is movably coupled to the front end portion 13a by a screw 21. In addition, one line cutting 20

The end portion % of the movable female rod 24 is rotatably coupled to the front end of the wire cutting rod 23. 14 1299763 发明, INSTRUCTION DESCRIPTION [0029] A middle portion of the movable blade 15 is rotatably coupled to the other end portion 24b of the movable female rod 24. One end portion of the movable blade 15 is rotatably connected to the fixing screw 25. The fixing screw 25 is fixed to the needle plate... The front end of the movable blade 15 is shaped to move the needle thread and the line axis without moving the cutting line of the cutting blade, and the wire is moved forward to be wrong. , the spring if the moving part 15b grabs the line - the line grabs the 胄 (5), and the movable knife 15d for cutting the line. Rotate down to the fixed knife on the needle plate & 10 15 20

Sin can be moved around the knife 15. A fixing knife 14a for arranging the movable blade 15 and for gripping the needle thread and the axis of the thread and the cutting line is formed at the front end of the fixed blade 14. [0030] The operation of the wire cutting mechanism 10 will be described below. It has a configuration of _, and the state τ of the 2A diagram when the wire cutting mechanism 1G is sewn. When the sewing is completed, the wire cutting link U is operated by the presser lifting mechanism 3 which will be described below.

Previously, the cam member 6G was rotated around the support handle 12 in the counterclockwise direction shown in Fig. i (arrow A direction). Therefore, the lower end portion of the wire (four) link U is just moved. As a result, the 'wire-cut connecting rod Η moves forward' as shown in Fig. 2B causes the 4 movable-linking connecting member 2G to be pushed by the screw 21. Therefore, the movable female connecting member 2 and the wire cutting lever 23 are rotated around the connecting screw 22. [0031] Due to the operation of the wire cutting lever 23, the movable female lever 24 connected to the front end of the wire cutting lever 23 is pushed rearward, so that the movable blade 15 is rotated by the clock 15 1599763 玖, the invention is rotated by the fixed screw 25 . Due to this rotation, the needle thread and the thread axis are operated by the private movement ° 15b, so that only the needle thread and the line axis to be cut are positioned in the line gripping portion He and the fixed knife Ha. [0032] On the other hand, the wire cutting link 11 rotates clockwise (four) around the support handle 12 so that the lower end portion of the wire cutting rod 11 returns to the rear, and the respective members constituting the wire cutting structure 10 are reversely rotated. . That is, the movable knife b is rotated 10 to return to its original state from the state of the 2B®. At that time, the movable blade 15 can move the knife 15 to rotate while grasping the needle thread and the thread axis by the wire gripping portion. Therefore, the needle thread and the thread axis are close to the fixed knife i4a. As shown in Fig. 2C, when the movable knife 15d and the fixed knife W meet each other, the q movement is cut.

The knife 15 continues to rotate in the reverse direction and returns to the state of Fig. 2A. [0033] Next, the configuration in which the pusher lifter mechanism 30 is lifted by a presser 31 and the structure 30 will be described.

The upper vertical and long pusher drive leg 36 is rotatably coupled to a front end portion 35a of the pusher drive arm 35. [0038] The presser drive leg 36 is substantially chevron on the horizontal portion and is designed such that When the lower edge portion 36a moves downward, the lower edge portion 36a is connected A contact pin of the presser 70. The presser 7A will be described later. A support rod 37 that is elongated in the lateral direction is rotatably supported at the center of the pusher drive leg 36. The other end of the support rod 37 can be Rotatingly connected to the undisplayed skeleton frame via a pin 10 such that the pusher drives the direction of the foot 36 to support the lever adjustment as it moves downward. [0039] A gap having a pre-twisted size is provided at the pusher drive foot 36 and positioned between the contact pins 73c of the presser 70 under the pusher drive leg 36. Because of this, the pusher drive leg 36 is designed to correspond to a delay time after the presser drive foot % begins to move downward. The contact plug 73c of the presser 7 is contacted. [0040] Here, the pusher drive leg 36 and the interconnecting arm 33 are designed to be interconnected as described above. One of the wire moving mechanisms 50, which will be described below, is connected to the interconnecting arm 33 by the slide arm connecting link 51. Therefore, when the pusher driving leg 36 starts to swing downward, the wire moving mechanism 5 以下 which will be described later is activated. On the other hand, a gap is provided between the presser driving leg 36 and the contact pin 73c of the presser 70.

19 1299763 发明, Invention Description [0045] Next, the configuration of the line moving mechanism 5A will be described. The line moving mechanism 5 is constituted by a (7) arm connecting link 51, a sliding arm l-shaped link 52, a sliding arm connecting plate 56, a sliding arm (line moving piece) 58, and the like. 5 [0046]

The wire moving mechanism 50 has a function of moving the needle including the needle and the needle thread on the cloth. After the needle thread is cut by the wire cutting mechanism 1 , the pressing device 71 of the pressing device 7 is lifted up to remove the needle side end of the cloth. Features. The rear end portion of the slide arm connecting link 51 of the line moving mechanism 50 is connected to the middle of the interconnecting arm 33 of the pusher mechanism 1 (see Fig. 1). [0047]

A side hole 51c which is elongated in the lateral direction is formed on a fulcrum end portion 51b of the slide arm connecting link 51. Further, the slide arm [shaped link 52 is substantially L-shaped and is disposed close to the front end portion 51b. The slide arm l-shaped link 52 is rotatably connected with its bent portion via an erecting screw 55 to an undisplayed machine frame. Then, an engaging pin 52a fixed to the upper end of the slide arm L-shaped link 52 is inserted into the lateral hole 51c of the slide arm connecting link 51. [0048] 2 A coil spring 53 that has been extended is disposed on the rear surface side of the slide arm connecting link 51. The end of the coil spring 53 is suspended from the portion of the slide arm connecting link 51, and the other end of the coil spring 53 is suspended from the engaging pin 52a of the slide f-L link 52. The slide arm L-shaped link 52 is always driven by the elastic force of the coil magazine 53 in the rightward direction of the sheet of Fig. 3 . [0049] 20 1299763 发明, DESCRIPTION OF THE INVENTION Incidentally, near the slide arm L-shaped link 52, a stopper bolt 54 is fixed to an unillustrated machine frame to protrude thereon. In order to activate the pusher lift mechanism 30 after the operation of the linear moving mechanism 50, the pusher drive link 32 is moved rearward to apply the elastic force of the coil spring 53 to the slide arm L-shaped link 52, and further move the slide arm L-shaped rearward. Link 52. Even in this case, the slider L-shaped link 52 is designed to be stopped at the slide arm L-shaped link 52 ® than the stop lever 54.

Incidentally, the elastic force of the coil spring 53 is insufficient to pull the slide arm L-shaped link 52 and the slide arm connecting link 51 rearward by the lift mechanism 10 by the lift mechanism 10. Therefore, only when the pusher lift mechanism 30 is activated to move the slide arm connecting link 51 backward, the coil spring 53 can be pulled and the slide arm L-shaped link 52 is moved backward via the engaging bolt 52a. [0051] 15 the slide arm connecting plate 56 is an elongated plate in a vertical direction, which is rotatably

The front end portion of the slide arm L-shaped link 52 is connected. An extension portion 56a extending rearward in Fig. 1 is formed at the lower end of the slide arm connecting plate 56. A support plate 57 fixed to a machine frame not shown is fixed to the vicinity of the slide arm connecting plate 56. The substantially L-shaped slide arm 58 in plan view is rotatably coupled to the support plate 57 with its bent portion 20 by a set screw 59. [0052] One end portion 58a of the slide arm 58 is rotatably coupled to the extension portion 56a. The forward moving one-line moving portion 58b is placed on the lower end portion of the slide arm 58 so that the needle thread is moved by the wire moving portion 58b. Fig. 4 is an enlarged perspective view showing the vicinity of the line moving mechanism 50 which is not activated by 21 1299763 玖, the description of the invention, and the first. Further, Fig. 5 is an enlarged view of the pusher lift mechanism 30 and the line moving mechanism 50 which have not been activated yet. [0053] The operation of the pusher lift mechanism 3A and the wire moving mechanism 5A will be described below. The configuration of the pusher lifting mechanism 3〇 and the line moving mechanism 5〇 is provided, and after the needle thread and the line axis are cut, when the pusher lift lever 31 is rotated in the clock direction (arrow direction) of the second figure, The pusher drive link 32 is moved backwards. By this operation, the pusher drive link 32 is swung back and forth about the shaft member 34, so that the pusher drive arm 35 also rotates in the clockwise direction about the shaft member 34. As the pusher drive arm 35 rotates, the pusher drive leg 36 moves downward while being adjusted by the support lever 37. On the other hand, when the slide arm connecting link 51 is moved rearward due to the swinging of the rearward arm 15 of the interconnecting arm 33, the engaging pin 52a in the lateral hole 51c is also moved rearward due to the elastic force of the coil bobbin 53. Therefore, the slide arm L-shaped link 52 rotates around the erecting screw 55 in the counterclockwise direction of Fig. 1 . By this rotation, the slide arm connecting plate 56 is lifted up. And due to this lifting action, the end portion 58a of the slide arm 58 is lifted so that the slide arm 58 rotates around the frame 20 5 and the screw 59 in the counterclockwise direction of the i-th image. Therefore, the needle thread is moved by the line moving portion 58b. [0055] Incidentally, the slide arm L-shaped link 52 stops rotating while abutting against the stopper pin 54*. The engaging bolt 52a slides along the lateral hole 51c (the distance moved further rearward relative to the arm connecting link 51) to block the distance 22 1299763. The description of the invention affects the operation of the slider L-shaped link 52. Fig. 6 is an enlarged perspective view showing the state in which the line moving mechanism 5 is activated. In addition, FIG. 7 is an enlarged view showing a state in which the pusher lift mechanism 3G and the line moving mechanism 5 are activated. [0056] Here, the contact pin 7 of the presser driving leg 36 and the presser 7 is opened. A gap is provided as described above. Therefore, after the pusher drive foot % starts to move downward for a predetermined delay time, after the needle thread is moved, the pusher driving leg 36 that moves downward pushes down the contact plug 73c of the presser 70 to lift the press device by 10 71. Incidentally, when the pusher lift lever 31 is rotated in the clockwise direction in the second figure to lift the pusher drive leg 36, the press device 7i is moved downward by its own weight. Further, when the interconnecting arm 33 is returned to its original position 15, the slide arm connecting link 51 is returned to the front. Therefore, the line moving mechanism % as a whole returns to the conditions in Figs. 4 and 5. As described above, the wire cutting mechanism 10 starts its operation at the wire cutting link 11 and the pusher lift mechanism 3Q and the wire moving mechanism 5G start its operation at the pusher lifter 31. The wire cutting link u and the pusher lift lever η are designed to be transmitted by the cam member 6G to the wire cutting link 11 at a predetermined time 及 and by the driving force of the pulse horse s 8 举. The pulse motor 80 and the cam member 6A will be described below. [0059] 23 1299763 发明, DESCRIPTION OF THE INVENTION In accordance with the present invention, the pulse motor 80 of the drive motor is used—the machine frame not shown. The intermediate portion of the cam member 6A, which will be described later, is fixed to the take-up shaft 81 of the pulse motor 80. The cam member 转动 is rotated by the pulse motor 80 at a predetermined angle. [0060] The driving of the pulse motor 80 is controlled by (four) _ 9Q (four) ^ _ cutting mechanism Π), the pusher lifting mechanism 3 〇 and the line moving mechanism 5 〇 to control the operation of the cam element 60 CPTT Qn γ a , Millennium RpU 9 (U stays 'and calculates the direction of rotation of the pulse motor 80 and its number of pulses during operation. 10 [0061] The 々 cam element 60 is composed of a first cam 61 and a second cam, such as the first and the second 8 A As shown in the figure, the first λ φ into the 1st cam 61 is a substantially circular housing, and on the outside of the housing, there is a straight portion from the front of Fig. 1. The first cam 62 and the first The front surface side of a cam 61 is integrally formed. [0062] In the first cam 61 as shown in Fig. 8A, a substantially heart-shaped cam groove 6U is formed on the rear surface side. The mating 11a of u is fixed into the cam groove 6U to slide on the surface thereof. [0063] 20. Fig. 8B shows the shape of the cam groove... For the sake of convenience, the labels P1 to P7 represent the number forming a circle. a point. The formation of the cam groove. From the point P2, the point P3 to the point P7 pulls out an arc that is equidistant from the center of rotation CM: another aspect From the point P2 to the point P7, the point is considered to be symmetrical with respect to the middle cam groove 61a, and the closer to the point P1, the closer the distance is. 24 1299763 发明, invention description from P2 through point P3 to point P2 to point P7 and Point η [0064] The portion of P7 is called the curved portion χι 〃, and the portion from the center is called the curved portion X2". The matching plug 11a is provided by as shown in Fig. 8B. The rotation of the cam member 6〇5 is relatively moved in the cam groove 61a. Therefore, for example, when the pulse motor 80 Μ is rotated in the predetermined direction (front), the matching check... passes the point P3 to the point p7 from the point P2. The curved portion moves. At this position, the distance between the matching pin 11a and the center of rotation and C1 is fixed. Therefore, the line cut_rod cannot be rotated. 10 [0065]

On the other hand 'When the matching bolt 11a moves from the point to the point? At 1 o'clock, the matching plug 11a gradually approaches the center of rotation π. Therefore, the wire cutting link 2 is rotated in the counterclockwise direction in Fig. 1 so that the movable blade 15 is moved outside the fixed blade 14a as described above. [0066] Next, when the matching pin 11a moves from the point Pi to the point p2, the matching check 11a gradually leaves the center of rotation C1. The wire cutting link u is rotated in the clockwise direction in the second figure, so that the movable blade 15 is cut by the fixed knife (4)

20 Lower the needle thread and the thread axis while grasping the needle thread and the thread axis. The same can also occur when the pulse motor 80 is rotated in the reverse direction so that the mating pin point P2 is moved to the point P7 via the point P1. That is, the bent portion χ 2_ is the wire cutting cam portion of the invention. The brother-cam 62 is integrally fixed to the front surface side of the first cam 61 [0067] 1299763 玖, the description of the invention 43 ^? The presser lifts the roller 8C of the lever 31/the cam surface 触 of the touch cam 62. For the sake of convenience, the numbers Q1 to Q7 in the figure are #矣& points. The angular position of the Ge table, that is, the number 510 15 20 which forms a circle, and (4) is pulled out from the point Q6 by the point φ to the point Q which is equidistant from the center of rotation C1. On the other hand, from point Q3 to point Q4 or from point Q6 to point 卯, the cam surface is symmetrical about the center of rotation, and the distance is closer to the point P4 or Μ. In addition, between the points q^Q5, the cam surface is condensed into an arc of equal distance from the center of rotation C1. The portion from the point through the point Μ to the point (10) is called, the curved portion γ is wide and from the point (10) to The part of point q.4 and is called the circular part γ2„. [0069] The roller 43 moves along the cam surface by the rotation of the cam member 6Q as shown in Fig. 8C. Therefore, for example, when the pulse motor 8 turns forward, the roller 43 moves from the point i to the point (10) via the point Q1. In this case, the distance between the roller 43 and the center of rotation ^ is fixed. Therefore, the pusher lift lever 31 cannot be rotated. On the other hand, when the roller 43 moves from the point Q3 to the point q4, the roller 2 gradually leaves from the center of rotation C1. Therefore, the pusher lift lever 31 is rotated in the counterclockwise direction in Fig. 1, so that the pusher drive link 32 is moved backward as described above. When the press device 71 is lifted, the slide of the line moving mechanism 50 is slid. The arm 58 is activated. 26 I299763 玖, invention description [0071] 10

Further, although the pulse motor 80 is rotated in the reverse direction, when the roller 43 returns from the point Q4 to the Q3, the roller 43 gradually approaches the center of rotation. Therefore, the M lifter lever 31 is rotated in the clockwise direction in Fig. 1 so that the pressing drive link 32 is returned to the front. Therefore, when the press device 71 is pulled down, the slide arm 58 returns to its original position before the operation. The same situation occurs with the movement of the rollers 43 between points Q6 and Q5. When the roller 43 is still moving toward the point, the (fourth) lifter lever 31 is rotated by the roller 43 in the counterclockwise direction of the third time. When the roller 43 moves toward the point Q6, the pusher lifts the lever η to rotate in the clockwise direction. That is, the elliptical portion γ2 corresponds to the linear movement cam portion and the pusher lift cam portion. Incidentally, the second cam 62 is formed in an arc shape between the points Q4 and Q5 for the following reasons. In the case of the press device 71, basically, the operation of moving the press device 71 upward and the operation of the press device 71 moving downward are reported.

Execute less continuously, but it is performed before and after sewing. Even if the pulse horse is stopped when the roller 43 reaches the points Q4 and Q5, the pressing device 71 is lifted, and there is a possibility of mechanical displacement between the stop of the pulse motor 80 and the stop of the rotation of the cam member 60. Therefore, the roller 43 can be slightly moved at the point Q4 20 or Q5. Therefore, the second cam 62 is formed in an arc shape between the dots and the turns to delay the stop motion. As a result, even if the roller 43 excessively rotates beyond the point Q4 or Q5, the press device 71 can be prevented from moving downward. [0073] The mutual phase relationship between the first cam 61 and the second cam 62 and 27 1299763 玖, the invention indicates that the contact positions of the first cam 61 and the second cam 62 with the matching check 11a and the roller 43 are set to 'make the line After the operation, the pusher lifting operation as described above is performed. In particular, the angle between the point and P7, the angle between the points, the angle between the points, and the angle between the points ... are the same (angle ml), so that the roller 43 corresponds to the matching bolt m From "P1 and move to P2, move from point Q7 to point (10) via point ^. That is, when the online cutting operation is performed, the pressing and turning mechanism does not need to be operated. [0074]

. Further, when the roller 43 is moved from the point Q3 to the point ^, and the pusher is lifted to be known as ¥, the matching pin 11a is moved between the points p3 and p4 so that the wire cutting structure is not activated. Further, when the roller 43 is moved between the points Q5 and Q6 to activate the pusher lift mechanism 3G, the mating plug (1) is privately operated at the points p5 and 使1 so that the line cutting mechanism 1 is not activated. When the roller is “positioned between points Q4 and Q5, the mating bolt (1) is positioned between points % and p5 15 〇 [0075]

Further, the cam member 60 has a zone (dead zone) where the driving force of the pulse motor 80 is not transmitted to the wire cutting mechanism 10, the presser lift mechanism 30, and the wire moving mechanism 5A. That is, when the matching bolt is positioned at the point and the roller 43 is positioned between the points Q2 and q3, and when the mating bolts & is positioned between the points P6 and P7, the roller 43 is positioned at the point Q6. When it is between Q7 and 7, the wire cutting mechanism 10, the presser lifting mechanism 3, and the wire moving mechanism 5 are not operated. That is, the area between the points P2 and p3 in the 8B picture, and the area between the points Q2 and Q3 in the 8C picture and the area between the points Q6 and Q7 are dead 28 1299763 玖, the invention description area 〇 [ 0076] The operation of the wire cutting mechanism 10, the pusher lift mechanism 30, and the wire moving mechanism 50 will be described below with reference to FIGS. 9A to 9C and FIGS. 1A to 10C. Figs. 9A to gc and Figs. 1A to i〇c are diagrams for explaining the operation of the cam member 60. The operation of the wire cutting mechanism, the wire moving mechanism 50, and the presser lift mechanism 3, which are sequentially activated, will be described below.

[0077] 10 First, the 'wire cutting operation' starts from the condition I shown in FIG. 9A. In this case I, the matching pin 11a is positioned on the curved portion X1 of the cam groove 61a of the first cam 61, and the roller 43 contacts the curved portion γι of the cam surface 62a of the second cam 62. [0078]

15 When the pulse motor 80 rotates forward under condition I (in F in Figure 9A)

In the direction), the cam member 60 is rotated in the clockwise direction in the first to ninth drawings. The matching plug 11a and the roller 43 move on the curved portions XI and γι, respectively. Immediately, the mating bolt 1 la is moved to the boundary position between the curved portion X and the curved portion 如2 as shown in the case II (Ρ7 in Fig. 8). At this time, the mating pin 11a starts to move on the bending portion ,2, so that the wire cutting mechanism 10 starts operating. Then, the matching plug 11a reaches the intermediate portion of the curved portion X2 as shown in the condition H1 (see Fig. 9C) (ρι in Fig. 8B). In this case III T, the movable knife 15 moves to a farther point as shown in Fig. 2B, 29 1299763 玖, invention description. Further, in the conditions π and ΠΙ, the roller 43 moves on the curved portion γι so that the pusher lift mechanism 30 does not operate. [0080] 10 15 20 Next, the matching pin 11a advances from the point P1 to the point ρ2 on the bending portion °2. At this time, the movable knife 15 is pressed to return to its original position, and the needle thread is caught in the operation. And the line axis, and the fixed knife 14 is engaged to cut the needle thread and the line axis. Then, the mating plug ua reaches the end position (ρ2) β of the curved portion 所示 2 as shown in the condition iv in the first drawing (i), at this time, the operation of the wire cutting mechanism ίο ends. Further, when the roller 43 moves between the point catch and /3 (dead zone) in Fig. 8c, the cam member 6 turns in the same direction, so that the mating plug Ua is at the point p2 & p3 in the cent map Move between (dead zone). At this time, the wire cutting mechanism 10, the pusher lift mechanism 3, and the wire moving mechanism 50 are not activated. [0081] Then, as shown in the (10)th figure, the roller 43 reaches the cam surface like (=: elliptical portion Y2 (" position (10) in the figure c). At this time, the first and the first are pressed by 31: 〇B is rotated in the counterclockwise direction, and after the rotating operation of the sliding arm 58 of the oscillating mechanism 50, the pressing cloth f is set to 71 = the portion between Q "Q5, and the rotation of the line moving mechanism U 58 and At this time, the pulse motor 8 is 纥 bundled. The plug Ua 2 is in the condition, the matching curved portion X1 moves. Therefore, the wire cutting mechanism does not operate.

30 1299763 发明, 发明说明 [0082] The electric power structure of the strip roughing machine according to this embodiment will be described below. Fig. 11 is a block diagram showing the electric power configuration of the strip roughing machine according to this embodiment. 5 [0083] The strip roughing machine includes a CPU (Central Processing Unit) 9A, a R〇M (memory) 91, a RAM (Random Access Memory) 92, an operation panel 93, and a press switch. 94. A switch 95, a pulse motor 8A, a spindle motor 100, and the like. The CPU 90 is a control device for driving and controlling each of the devices such as the pulse motor 8A. The ROM 91 stores information such as control data or programs. The RAM 92 stores data that is different from the cPU 90 based on data or programs read from the R〇M 91. The operation panel 93 is used to input a sewing situation or the like. The pusher switch 94 is used to drive the presser 70 to press the cloth. The start switch 95 is used to start sewing. [0084] The CPU 90 executes different processing in accordance with the pattern data or the sewing program stored in the ROM 91, and uses the RAM 92 as a work area. In particular, θ, the CPU 90 selects and changes the sewing data according to the operation panel connected to the cpu 9〇 via an undisplayed input interface, and further, responds to the start switch of the CPU 90 by the wheel 20 interface of the two. 95 or the indicator signal of the pusher switch 94, the CPU 90 controls the pulse motor 80 and the spindle motor 1〇〇 via an undisplayed wheel-out interface according to the pattern data to execute a predetermined stitching 0 [0085] 1299763 玖, [Explanation of the Invention] Hereinafter, the twisting insertion of the strip roughing machine according to this embodiment will be described with reference to a flowchart or the like. Fig. 12 is a flow chart for explaining the control insertion of the long slitting machine according to this embodiment. Figs. 13A and 13B are diagrams showing a list of control data (pattern data) for controlling the operation of the strip slitting machine according to the embodiment of the present invention. Further, Fig. 4 is a view schematically showing the control operation of the crevice machine according to this embodiment, and focuses on the moving distance of the wire cutting link n and the presser lift lever 31. [0086] First, the control operation of the long strip 1 quilting machine according to this embodiment will be described with reference to the flowchart of Fig. 12. First, a flag for defining the direction of rotation of the pulse motor 80 is set to have an original value controlled by the CPU 91 (initial rotation direction setting step: S1). Next, when the user operates the pusher switch 94, the CPU 90 that receives the operation signal from the presser switch 94 drives the pulse motor 80 to rotate the cam member 6''. Therefore, the press cloth 15 of the presser 70 is pulled down by the pusher lift lever 31 or the like to press the cloth (cloth pressing step: S2). [0087] Thereafter, the CPU 90 sets the original value of the address of the pattern data read from the ROM 91 (data address starting step: S3). Incidentally, when the user 20 is not operated with the pusher switch 94, the CPU 90 does not drive the pulse motor 80' and waits until the presser switch 94 is operated. [0088] Next, the user operates the start switch 95 to start sewing, and the CPU 90 that receives the operation signal from the start switch 95 reads the sewing data included in the 32 9199763 玖, invention description pattern data included in the ROM 91 (performance system) %% clothing (a sewing machine, take steps), and sewing according to the sewing data. By the way, the θ fire, 疋' s user operation start switch 95%, CPU 90 does not read the sewing data , was stayed as a stop [0089] ... a bedding ten and special treatment until the start of the switch 95

Next, when the instruction to sew the material in the pattern data in the RQM 91 is 'the line cutting command eve (for example, the data address 1G56 in the $13 octagon), the CPU 9G drives the pulse motor 8G to rotate the cam element. The state 1 from the state 1 in Fig. 9A is slightly rotated in the clockwise direction (the arrow F in the maps 9A to 9C and 10A to 1〇c) via the state v in the head to the cam 10 member 6〇. Therefore, only the line (four) mechanism 1 () and the line moving mechanism 50 are activated (wire cutting / line moving step: S5). [0090]

Here, due to pressing! § A gap is provided between the lower end 36a of the presser driving leg 36 of the lifting mechanism 3 and the contact plug 73c of the presser 70, and the lower end 36a of the pusher driving leg 36 is at the first 〇B of the cam member β〇 In the state of the figure V, the contact plug 73c of the presser is not touched in a state of being slightly rotated in the clockwise direction. Therefore, the press device 71 is not lifted. [0091] Incidentally, when the instruction of the sewing material in the pattern material following the ROM 91 is not a line cutting instruction (for example, the address 1001 in FIG. 13A), the CPU 90 executes the pattern data. Another instruction (in another instruction execution step · S6) (for example, a preliminary feed instruction). Then, the CPU updates the address of the pattern data (data address update step··S7) and returns to the sewing read 33 1299763 发明, invention description step S4 to continue the sewing work. [0092] After the online cutting/line moving step S5, the CPU 90 updates the address of the pattern data in the ROM 91 (data address updating step: S8), and the instruction of the line cutting instruction following the 5 in the pattern data is When the sewing end command 〃 (for example, the data address l〇7C in Fig. 13A), the CPU 90 drives the pulse motor 80 to rotate the cam member 60 and guide it to the condition VI in Fig. 10C. Therefore, the presser lifting mechanism 30 is activated (presser lifting step: S9). Then, the sewing work is over. [0093] On the other hand, when the line cutting instruction in the pattern data is followed, the 'sew end instruction κ譬, the data bit in the 13A picture is the preliminary feed data in 1057,) , cpu 9〇 delayed pulse motor 8〇_ 15 20

The predetermined time (pulse motor delay step: sl〇) ' At this time, the cam element 6 has slightly rotated in the clockwise direction under the condition V of the 1st GB, so that ^

The lower #36a of the pusher driving leg 36 does not contact the contact name 73c of the presser 7q. Therefore, the press device 71 has not been lifted. [0094] ...long search for the rotation square flag of the pulse motor 80 (flag reversal step: Si 1 ), in order to rotate the pulse motor j in reverse and stop it, so that the cam element 6 is judged The situation of Yundi 10A is Iv (motor reversal step: S12). Then, ρρπ * - after the CPU returns to another command S6 to continue the sewing work. - 34 [0095] 1299763 发明, DESCRIPTION OF THE INVENTION When the cam member 60 is between the condition iv of FIG. 10A and the condition V of the ι〇β map, the matching pin 11a is positioned between points p2 and p3 in the 8th figure. (dead zone), and the roller 43 is positioned between points Q2 and Q3 (dead zone) as in the aforementioned Fig. 8c. Therefore, the wire cutting mechanism 1〇, the presser lifting mechanism 530, and the line moving mechanism 5 are not activated. [0096] As described above, the control operation 'wire cutting/line moving step S5, the material updating step, and the presser lifting step S9, which are completed after the sewing reading step S4, corresponds to the control mode of the present invention. A mode can be achieved by the forward or backward rotation of the pulse motor 80. The cam portion χ2 of the first cam 61 of the cutting line cam member 60 and the line moving cam portion of the second cam 62 and the pusher lifting cam portion are respectively arranged symmetrically so that the wire cutting mechanism 、) and the line moving mechanism 5Q And the operation of pressing the turning mechanism 30, regardless of the direction of rotation of the pulse motor 8〇 is fixed 15 ° [0097] On the other hand, 'the sewing operation is continued after the sewing data reading step S4, the wire cutting/ The line moving step S5, the data address updating step S8, the pulse motor series (4) S1G, the Wei inversion step sn, and the pulse motor 20 inversion step S12 correspond to the 'second control mode' of the present invention. [0098] 'Fig. 13A shows The pattern data (A) used to achieve a control plane, in which the brother-sewn system is based on a set of sewing materials.

The scalding is performed, and then the next sewing is performed in accordance with the group of lean materials without starting the pusher wrap raising mechanism. In addition, 35 1299763 玖, invention description 中 '第__示心达到_Control touch sewing according to a set of stitching (2) mussels (B), its [_] L shell shake and then finish the sewing work.

At this time, the first control mode is achieved by driving the pulse motor 80 in the reverse direction of the rotation direction. [0100] 15

On the other hand, the general stripe work can be achieved by the pattern data (8) shown in Fig. 13B. In order to achieve the pattern data (8) as shown in FIG. 13B, the sewing data reading step (4), the line judgment/line moving step S5', the data address updating step S8, and the presser lifting step S9 shown in FIG. Then the sewing work is completed (the first control mode is reached). [0101] Fig. 14 is a view showing the moving distance of the wire cutting link u and the riser lift lever 31 up to the cam member n. The degree of rotation is one revolution (0. _36.). In Fig. 14, the 'cam start point 〃 corresponds to the condition ί ' in the Fig. 9A, the line cutting start point &quot; corresponds to the condition in the ninth diagram „,, 'line cut 36 1299763 玖, invention It is indicated that the cutting-edge point &quot; corresponds to the shape in Figure 9C, and the line-cutting knot-occupies the situation IV corresponding to Figure 10A.,,, // m ^ ^ 卜's starting point of the sliding arm corresponds to the 10B figure The situation V in the middle, and the 顶点10rRi smashed the apex &quot; corresponds to the situation π in the 10C. [0102] The <Example A> in Fig. 14 is roughly shown to perform the X-shaped length The operation of the strip is not allowed to leave (4) the operation of the transverse stitching, or the work of sewing four or more slits on the cloth, and the control operation is achieved by the pattern data (A) which is not in the mouth of the third a 3a 10 15 20 . In <Example A>, first, the sewing tract reading step S4, the wire cutting/line moving step S5, the data address updating step S8, and the pulse motor delaying step s1 所示 shown in Fig. 12 are performed. At the end of the motor delay step ,, the cam member 6 is on the opposite side, and you should be in the shape of the end of the sliding arm in the figure of the brother 14 [0103] Corresponding to the condition of the end point of the slide arm in Fig. 14, that is, the cam element 6 has been slightly rotated in the clockwise direction under the condition v in the (10) figure. When the cam member 60 Positioning on the arm, the arm of the sliding arm, the upper jaw of the arm, the rotation of the sliding arm 58 of the line moving mechanism 50, the operation of the gentleman φ 2 &amp; the shovel, the mouth bundle, and the pressing device of the presser 70 71 has not yet been lifted. This condition can be achieved as described above by the presser of the presser lifting mechanism 3 驱动 driving the lower end of the leg 36 6 β 36a and the contact plug π of the presser 7 。. [0104] Next, 'the flag reversal step S11 and the pulse motor reversal step S12 are performed to reverse the pulse cymbal (9) at the end of the 'sliding arm end. When the pulse 37 1299763, the invention indicates that the motor is reversed. At the end of step S12, the cam member 6g is in the state of the "fourth" "slide arm end point" (the state V of Fig. 10B). [0105] Thereafter, the sewing data reading step S4, the wire cutting/line moving step S5', the feeding address updating step S8, and the pressing surface step S9 are performed by the inverted pulse motor (10). Therefore, the sewing of the guard is over. When the presser is lifted up at the end of step S9, the cam element corresponds to the apex of the presser in the Fig. 5 (the situation VI of Fig. 10C). [0106] 10 15 20 &lt;Example B&gt; in Fig. 14 schematically shows a control operation for performing a general X strip roughing operation, which can be performed by the pattern shown in Fig. 13B Information (8) was reached. At the thorn (4), the sewing operation ends after the sewing data reading (4) S4, the wire cutting/line moving step S5, the data address updating step S8, and the pressing material step S9. When the presser lifts the step S9, the cam member 6 is in the state corresponding to the ''presser apex in Fig. 14 (the condition VI in Fig. 10C). [0107] In the strip roughing machine according to this embodiment, the three operations, that is, the wire cutting operation, the wire moving operation, and the presser lifting operation, can be mechanically driven by a single drive motor after delaying each other for a period of time ( The pulse motor is called an actuator. Therefore, it is not necessary to provide a driving device for driving the wire cutting mechanism 1 (and the pusher lifting mechanism 30), and a driving device for driving the wire moving mechanism 50, and The prior art is to control these individual driving devices in a sample manner. Therefore, the wire cutting mechanism 1〇, the wire moving mechanism 5〇 and 38 1299763 玖, the invention shows that the presser lifting mechanism 3〇 can always be activated between the solids [0108] In particular, in this embodiment, the presser lifting mechanism 3G presses the lower end of the crying foot 36, such as the contact plug of the presser 7〇, between the 5" and "13" lines. The movement operation and the pressing of the transfer material simultaneously perform the lamp, and the delay time between the end of the line moving operation and the start of the presser lifting operation is always fixed. [0109] Furthermore, in the strip roughing machine according to the present invention , cut 1〇 with a rotating wire Mechanism 2, the pusher lift mechanism 3G and the drive mechanism (pulse motor 8G) of the drive mechanism of the line moving mechanism 5G are set to be early. Therefore, it is not necessary to prepare the drive line mechanism as in the prior art. 1() and a driving device for pressing the lifting mechanism 3〇, and a driving device 15 for driving the wire moving mechanism 5〇 [0110] Further, in the long slitting machine according to this embodiment, the first cam 6ι The wire cutting cam portion X2 of φ and the wire moving cam portion of the second cam 62 and the pusher lifting cam portion Y2 are symmetrical with each other such that the wire cutting mechanism 1〇, the wire moving mechanism 50, and the presser lifting mechanism 30 regardless of the pulse motor 80 The rotation direction of each of the two sides has a fixed operation. Therefore, regardless of whether the pulse motor (9) is rotated to the rain or backward, the wire cutting, the wire moving, and the solid pressing can be performed. In order to achieve a smooth sewing work - [0111] In addition, in the long slitting machine according to this embodiment, the cpu 90 is provided with 39 1299763 玖, the invention describes that the control is set to control and achieve the pulse motor (9) Rotate in the _ direction to make the line The cutting mechanism 1G, the line moving mechanism 5G, and the (fourth) lifting mechanism 3 are sequentially activated, and the pulse motor 8G is rotated in the -rotating direction 5 so that the wire cutting mechanism 10 and the wire moving mechanism 50 are sequentially activated. The pulse mode motor 80 is rotated in the reverse direction so that the rotational position of the pulse motor (10) is positioned at the dead zone before the start of the lifter mechanism 30. This precise sewing operation can be completed according to different conditions. [0112]

For example, in the case of sewing a four-hole (10) opening to the cloth (see <Example A&gt; of 10 in the figure), if the sewing work is desired to be continuously performed on the supporting cloth, the pressure of the pressing device 70 is not raised. The cloth device 71 is continuously completed in the state of the cloth device 71. First, the CPU 9G reaches the second control mode. Then, after the first suture formation line, the J mechanism 1〇 and the line moving mechanism 5〇 can be started when the presser lift mechanism 3 is blocked from operating. Secondly, the first control mode is achieved by the coffee machine to 70% down-stitch. Therefore, the problem of the cloth slip caused by the presser lifting mechanism % lifting "lifting the pressing device 71 of the presser 70" does not occur. Therefore, the sewing work can be performed efficiently. [0113] Furthermore, when it is not desired to form a transverse stitch between the first suture and the next suture, the first and subsequent sutures can be immediately smashed in the following manner, the CPU 90 establishes a second control mode to form a first seam, a spring. Thereafter, only the wire cutting operation and the wire moving operation are performed when the presser lift mechanism 30 is blocked from operating. Next, the first control mode is established by cpu (8) to form the next stitch. Therefore, no transverse stitching is formed between the first suture and the suture of the article 12 1299763, which describes the product that can be improved. Therefore quality. [0114] Incidentally, the present invention π + + ia is not limited to the disclosed embodiment, and may be modified locally, for example, when the presser lift mechanism 30 is not activated by the online moving mechanism 50 (second control) Mode), when the line moving mechanism % is driven, the RMT ^ position of the pulse motor 80 is controlled by the CPU 90 so that the slide arm 58

The swingable range can be changed to be narrower than the range in which the stopper plug 54 is adjusted. [0115] 1〇, that is, the stopper plug 54 prevents the sliding arm 58 from lifting the mechanism with the presser

The operation of 3〇 is more oscillating than necessary. However, in the second control mode in which the pusher lift mechanism 30 is not activated after the start of the linear movement mechanism 5, the moving distance of the pusher drive link 32 is controlled under the control of the CPU 9〇, so that the swing of the slide arm 58 is performed. It can be stopped before the stopper plug 54 is adjusted. Therefore, the movable area of α 5 8 can be changed. Further, the movable area at that time can be set via the operation panel 93. That is, the CPU 9 has a function of a movable area changing means for changing the movable area of the slide arm 58 of the line moving mechanism 5. [0116] The CPU 90 is provided as a movable area changing device, and the movable area of the sliding arm 58 can be appropriately set according to the thickness of the intended sewing cloth. As a result, the slider arm 58 is prevented from swinging more than necessary. Therefore, the time required to swing the slide arm 58 can be shortened, so that the sewing efficiency is increased. [Advantages of the Invention] 41 1299763 Rose, Invention Description [0118] According to the present invention, three operations, namely, wire cutting, wire movement, and presser lifting operation, can be performed by a single-motor by mechanical force, and Start after mutual operation for a while. Therefore, it is not necessary to separately provide a driving device for driving the wire cutting mechanism (5 presser lifting mechanism), and a driving device for driving the wire moving mechanism to control the respective driving devices. . Therefore, the wire cutting mechanism, the wire moving mechanism, and the pusher lifting mechanism can always be started at a fixed time. As a result, the loop delay can be prevented. [0119] Further, in accordance with the present description, the driving device for driving the wire cutting mechanism, the pusher lift mechanism, and the wire moving mechanism is a single drive motor. Therefore, it is not necessary to provide a driving device for driving the wire cutting mechanism (presser lifting mechanism) and a driving device for driving the wire moving mechanism. The sewing machine with small size and light weight can be made at a low price. 15 [0120] In addition, precise sewing work can be performed according to different conditions. [0121] Lu Ru's want to sew a four-hole button on the cloth without leaving any transverse stitches. In this case, if the sewing operation is desired to be continuously completed in the support cloth, and the cloth presser of the press device is not lifted, first, the second mode is established by the control device. Therefore, after a suture is formed through the two holes, the wire cutting mechanism and the wire moving mechanism are activated, and the presser lifting mechanism is prevented from being found. Second, the control device establishes a first control mode to form a suture through its two holes. 42 1299763 发明, INSTRUCTION DESCRIPTION [0122] Therefore, there is no problem that the cloth sliding device of the press machine is lifted as the presser lift mechanism is activated to cause the cloth to slip. Therefore, the sewing work can be performed efficiently. [0123] Further, if it is desired to form a suture stitch between the first suture and the next suture for aesthetic reasons, the first and subsequent sutures can be formed in the following manner. That is, the second control mode is established by the control device to form the first stitch. Thereafter, the wire cutting operation and the wire moving operation are performed, and the presser is lifted and the mechanism is blocked. Second, the first control mode is established by the control device to form the next seam, line. Because there is no transverse stitching between the first stitch and the next stitch. Therefore, the quality of the sewn product can be improved. [0124] In addition, it is possible to prevent the wire moving piece from swinging more than necessary. Therefore, the suffix can be used to oscillate the time of the moving piece to improve the sewing efficiency.
