Field of the invention The present invention relates to a method and a device for forming a sewing thread of a sewing machine, and more particularly to a cloth for forming a cloth such as a car seat, furniture or the like. A method and component of a seam of a piece of raw material or leather, in which two pieces of a piece of sewing material are aligned on the front side and the ends are sewn together to open the sewing material for use, and the sewing part is located One inside. 10 Description of Related Technology In the conventional case, for example, when the above sewing is performed by a sewing machine as shown in FIG. 7, firstly, the top sides of the upper cloth W1 and the lower cloth W2 are aligned, and then a needle and A shuttle cooperates to sew the side edges of the upper and lower cloths together with the upper thread NS and the lower thread usa lock suture. Subsequently, as shown in FIG. 9, 15, the upper cloth W1 and the lower cloth W2 are stitched together at the inner ends to be opened and used. The problem solved by the present invention However, as shown in FIGS. 7 and 8, the strength of the fastening force on the sewing part depends on the respective tensile strength of the upper line NS and the lower line US, and the upper line NS and the lower line 20 US are in one of them. The frictional force on the nodes and the frictional force generated between the upper line NS and the lower line US across the top and tail sides of the upper cloth W1 and the lower cloth W2. Therefore, the strength of the fastening force on any sewing part depends on a single thread. In addition, when the sewing part is opened, the upper line NS and the lower line US are stretched, and the nodes of the upper line NS and the lower line US are deformed to cause the upper cloth W1 and the lower cloth W2 to continue to the upper line 0.

Therefore, when the sewing part is opened, the contact surfaces of the cloth W1 and the lower cloth W2 above the node are exposed, as shown in FIG. 9, causing the nodes of the upper line NS, the lower line US, or both to appear on the upper cloth W1. And the problem of destroying the value of Shang 5 industry by disposing the top side of W2. In addition, in order to increase the strength of the nodes by the online NS and offline US, it is conceivable to increase the size of the online NS and offline US and increase the pulling force of the online NS and offline US. However, according to the lockstitch sewing machine, the nodes are formed at the center of the upper and lower fabrics by the tension of the upper and lower threads 10 and 10 of the balance US, and a thin plate spring is used to apply the tension to a reel The component of the offline US on the box. This structure has a restraint in increasing the pulling force of the offline US, so it cannot provide a large pulling force to the online NS and offline US, and also has the ability to enhance the node force by the online NS and offline US. limit. 15 Moreover, even if it is assumed that increasing the pulling force to sew the cloths together as described above will still cause a problem when the impact is applied to the part where the sewing part is opened, as shown in Figure 9, the upper line NS, the lower line US, or both The node system appears on the top side of the upper cloth W1 and the lower cloth W2 and destroys the commercial value. Furthermore, even when the fastening force is increased by using the combined suture created by combining a plurality of threads like a double combined suture or a covered combined suture 20, the combined suture is partially cut when a combined suture is partially cut. The thread will fray from the cut portion and cause durability problems. In addition, although it is conceivable to increase the strength of the fastening force by sewing the conventional stitches of the stitched part again so that the stitches overlap, in this case, the last 0 pages (the description page of the invention is not enough to use , Please note and use the continuation sheet) 7-:. _ .. ·. ... ... The cloth and the lower cloth must return to the starting sewing position and sew again, which causes the problem of reduced operation efficiency and the needle is difficult to puncture The same suture portion that was previously stitched is worn, and the nodes of the upper line NS and the lower line US cannot be prevented from deforming. And 'Although it is conceivable to sew the upper cloth W1 and the lower cloth W2 by two stitches HS1 and HS2 as shown in Fig. 10, it takes a long time to form a suture and it is impossible because of the length of the thread. The problem of forming long sutures. The way of the problem. In order to solve the above-mentioned conventional problems, the invention of the first scope of the patent application is a method for forming a suture of a sewing machine, which is repeatedly supplied by a cloth. The component supplies the cloth with (n + 1) stitches in one direction to form a plurality of stitches, and then uses a sewing machine for forming a locked stitching with n stitches and the same in a direction opposite to the one direction The amount of supply is reversely supplied to the cloth to form a seam to continuously form a seam on the cloth. According to the invention of item 1 of the scope of patent application, the upper cloth and the lower cloth are sewn together by a locking suture for fixing the suture to each suture, and a plurality of nodes are provided at respective suture points, Therefore, the respective tensile strengths of the upper line NS and the lower line us are increased, and the friction of the nodes of the upper line NS and the lower line US at the respective suture points is also increased. In addition, since the upper and lower wires NS and US are across the top and rear sides of the upper and lower cloths W1 and W2, a large friction force is generated between the upper and lower wires Ns and US2 and between the upper and lower cloths W1 and W2. In addition, the strength of the tightening force is spread across a plurality of lines. According to the description above, when the sewing part is opened, the upper and lower NS and lower thread 0 continued pages (when the invention description page is insufficient, please note and use the continued page) 567261 Will be reduced, and the deformation of the nodes of the upper line NS and the lower line US will be reduced, and the compression of the upper cloth w 1 and the lower cloth W2 at the contact portion of the upper line NS and the lower line US and the upper cloth W1 and lower cloth% will be extremely reduce. Therefore, it is possible to avoid opening the contact surfaces on the sewing portion of the upper cloth W1 and the lower cloth 5 W2 when the sewing portion is opened. In addition, even when an impact is applied to a part where the sewing portion is opened, the nodes of the upper line NS, the lower line US, or both do not appear on the top sides of the upper cloth W1 and the lower cloth W2, and thus have excellent impact resistance. And enhance the commercial value of the product. Also, even when the thread at the suture is partially cut, because the suture is 10 locking sutures, the thread will not be worn away from this part, thereby achieving the effect of excellent durability. In addition, according to this sewing method, the cloth can be continuously sewn, so that the effect of improving the sewing operation efficiency can be achieved. In addition, the needle can pierce the same part of the previous sewing thread 15, which can prevent the nodes of the upper NS and the lower US from being deformed, thus achieving the effect of improving product quality and increasing the commercial value of the sewing product. The invention claimed in the patent scope is a method for forming sutures according to item 丨 of the patent scope, in which a cloth is stitched together with two sutures by repeating in one direction and then in a direction opposite to the one direction The cloth is sewn together with a single stitch 20 in the direction to form a continuous stitch on the cloth.

Description of the invention ^ Continued description of the invention 裒 The first embodiment of the present invention is described below with reference to FIGS. 1 to 6 . In principle, a cloth supply member 29 shown in FIG. 2 is provided with a structure similar to a cloth supply mechanism of a conventional well-known sewing machine. The number 9 represents one of the main shafts of the sewing machine. The number 10 represents one of the main shafts 9. Eccentric cam. Reference numeral 11 denotes a cloth supply amount converter, a central portion of which is rotatably supported by a bed sewing machine via a shaft 12. The supply converter. The base of the two links 13 and 14 with the same length on one left end is pivotally supported by coaxial shafts 13A and 14A, and the front ends of the links 13 and 14 are connected by a common shaft 15 and a supply The control mechanism includes a supply amount converter, links 13 and 14, and shafts 12 and 14. The number 16 represents a direct-moving motor fixed to a rack (not shown), and a right end of the actuator 17 and the supply amount converter 丨 is pivotally connected by a link 18. Numeral 19 denotes a vertical link having an upper end connected to the eccentric cam 10 and a lower end pivotably connected to the shaft 15 at the front ends of the links 13 and 14. The number 20 represents a horizontal supply shaft and it is pivotably supported by a machine tool (not shown). A right end of the horizontal supply shaft 20 is fixed to a lower end of an upwardly protruding arm 21, and a left end thereof is connected to the The lower end of one arm 22 of the upper protrusion is fixed. Reference numeral 23 denotes a connecting link, one end of which is pivotably connected to the shaft 15 on the front ends of the links 13 and 14, and the other end of which is pivotably connected to a front end of the arm 21. The reference number 24 represents a cloth supply arm, one end of which is pivotably connected to a front end of the arm 22, and the other end 25 of the other end is loosely fitted to a vertical cam 27 located on a vertical moving shaft 26. The reference number 28 represents a cloth supply drafter fixed to one of the cloth supply arms 24. 0 Continued pages (Please note and use continuation pages when the invention description page is insufficient.) 567261 According to the cloth supply mechanism 29, when the sewing machine is driven to rotate the main shaft 9, the vertical link 19 is vertically moved by the eccentric cam 10. Therefore, the connection The shaft 15 to the lower end of the vertical link 19 is vertically moved by a fixed amount. The vertical movement of the shaft 15 is transmitted to the horizontal supply shaft 20 to cause the cloth supply puller 28 to perform a supply motion. That is, in a case where the shafts 13A and 14A are arranged on a straight line (FIG. 3A) connecting the upper end of the arm 21 to the shaft 15, when the shaft 15 is vertically moved by the vertical link 19, although the links 13 and 14 Centering on the shafts 13A and 14A and pivoting, the upper end of the arm 21 does not cause a displacement in the horizontal direction, and the cloth supply draft 10 and 28 are static, so the cloth supply effect is not performed. In the case where the shafts 13A and 14A are arranged on the upper side of the straight line 连接 connecting the upper end of the arm 21 and the shaft 15 (Fig. 3B), when the shaft 15 is vertically moved by the vertical link 19, 14 is centered on the shafts 13A and 14A and pivots. The shaft 15 connected to the front ends of the links 13 and 14 is a pivot track as shown in FIG. 3B during the day. Therefore, the front end of the arm 21 is horizontal. Displacement occurs, so the cloth supply drafter 28 performs a cloth supply motion in a normal supply direction in a state of protruding from an upper surface of a needle throat (not shown). In addition, since the positions of the shafts 13A and 14A are separated from the straight line for connecting the upper end of the arm 21 and the shaft 15 above, a displacement amount of the arm 21 in the horizontal direction increases, and the cloth supply puller 20 28 is in the normal supply. The supply of one cloth in the direction increases. In addition, when the shafts 13A and 14A are arranged on the lower side of the straight line 连接 connecting the upper end of the arm 21 and the shaft 15 (FIG. 3C), when the shaft 15 is vertically moved by the vertical link 19, the links 13 and 14 are fixed. The axis 15A and 14A are pivoted. The axis 15 draws a pivot track as shown in Fig. 3C. Therefore, it has the opposite phase to that of Fig. 3B. Continued pages. (Use continuation sheet) 12 • ... ..: ':-......' The horizontal displacement of the position is generated at the upper end of the arm 21, so the cloth is supplied to the drafting tool 2 8 The cloth supply motion is performed in the reverse direction with the upper surface of a needle throat (not shown) protruding. Further, since the positions of the shafts 13A and 14A are separated from the straight line for connecting the upper end of the arm 21 and the shaft 15 below, the supply amount of cloth in the opposite supply direction increases. With this method, the cloth supply direction and the cloth supply amount in the normal direction and the opposite direction depend on the positions of the shafts 13A and 14A, and the positions of the shafts 13A and 14A located at the front ends of the links 13 and 14 can be controlled by the direct movement motor 16 . That is, when the actuator 17 that directly moves the motor 15 configures the lower end 10 of the connecting rod 18 so that the positions of the shafts 13A and 14A become the middle position that is the same as the straight line (intermediate position), the supply amount is as described above. Eliminate. When the actuator 17 is lowered so that the lower end position of the link 18 is lowered relative to the middle position, the cloth supply converter 21 is centered and pivoted clockwise on the shaft 12, and the shafts 13A and 14A arranged on the upper side of the straight line Η The position depends on the lowering position of the actuator 17, thereby determining the general supply direction and the supply amount. Further, when the actuator π of the motor 16 is directly moved to raise the lower end position of the link 18 relative to the intermediate position, the cloth supply converter U is centered on the shaft 12 and pivoted counterclockwise. The positions of the shafts 13A and 14A arranged on the lower side of the straight line Η are determined to determine the positions of the shafts 13A and 14A, and the reverse supply direction and the supply amount are determined by the raised position of the actuator 20. In other words, the cloth supply direction and cloth supply amount are determined by driving the direct-moving motor 16 with the vertical position of the actuator 17.

The operation according to the first embodiment of the present invention will now be described. The first embodiment is an example when the needle is lowered (n + 1) times in the normal supply direction and the needle is lowered n times in the reverse supply direction. By the way, the first embodiment is a case where η = 1. First, in an input setting sub-stroke formula, η = 1 is input as input data of the number of times of needle drop by the input member 8 (S-1). Then, the direct drive motor 16 receives a command from the control circuit 7 and is driven by the drive circuit 6 to form a drive amount (S-2) corresponding to a normal supply amount set by the input. Therefore, the actuator 17 is lowered. And it is set to a predetermined supply amount in the normal direction. Then, when the foot press plate is pressed and a start signal is generated from the start switch 1 (S-3), the sewing machine motor 5 is driven by the drive circuit 4 (S-4) to start 15 the sewing machine to form a seam. The needle position signal from the needle position detector 2 is counted by the counter in the control member 3. As long as the foot brake plate does not release to generate a stop signal but maintains its current status (S-5), the needle drops for the second time And the counter calculates n0 = n + 1, that is, the actuator 17 that directly moves the motor 16 is kept in the lowered position until the cloth is fed in the normal direction after the needle stops for the first time, and the needle is continuously lowered (S- 6). The direct movement motor 16 receives a command from the control circuit 7 and is driven by the driving circuit 6, and then forms a driving amount corresponding to a reverse supply amount set by the input (S-7). Therefore, the actuator 17 is raised to set a same supply amount in the opposite supply direction as in the normal direction. 0 Continued pages (Note when the invention description page is inadequate, please note and use the continuation page) 15 567261 The invention is true, the invention explains when the counter counts n by a continuous signal from the needle position detector 2. When = 1 (S-8), the direct movement motor 16 is driven to constitute a set normal supply amount (S-9). In addition, before stopping the signal input (8_5), repeat the operation of fabric supply in the normal direction during the interval of the needle lowering twice and fabric supply in the opposite direction during the continuous lowering of the needle. In other words, the operation of supplying the cloth in the ordinary direction during the interval of the needle lowering twice and then supplying the cloth in the opposite direction and the same cloth supply amount as the ordinary direction and lowering the needle once is repeatedly performed, thereby forming a copy Stitching. 10 Now, referring to Fig. 4, a state for forming an actual suture will be described. And 'Although the upper thread ns 1, NS2, NS3 and the lower thread US1, US2, US3 are separated above and below from one of the upper cloth wi and the lower cloth W2 according to a stitch shown in FIG. 4, Actually, the thread is strongly fastened at each suture, so the upper and lower threads are in strong close contact with the upper and lower surfaces of the upper cloth W1 and the lower cloth W2 15. The direct movement motor 16 is driven to a lowered position corresponding to a normal direction supply amount p. When the sewing machine motor 5 is driven, first, the needle is lowered to a suture point A in FIG. 4 and a perfect suture is formed.跸 1A. Subsequently, the upper cloth W1 and the lower cloth W2 are supplied with a supply amount of 20 P in the ordinary supply direction marked by the X direction, and the needle is lowered to a suture point B to form a node 2A of a perfect suture. A counter is used to count the number of times of the above-mentioned second needle drop (n0 = n + 1), and η is set so that n0 = 2, and a command is generated from the control circuit 7 to directly move by the instruction from the control member 3. The actuator 17 of the motor 16 is arranged in a raised position corresponding to the reverse supply amount p which is equal to the normal supply amount, and the cloth wi 0 is continued on the next page (when the invention description page is insufficient, please note and use the continuation page ) 16 Rose, invention description. : ^ 发 Zen description __ and the lower cloth W2 supply the supply amount p in the reverse supply direction of the arrow mark γ, and the needle descends to the suture point A and forms f: and a node 3 a of the suture front. When the number of needle drop times is counted at the suture point after reverse feeding ~ = 1, the actuator 17 that directly moves the motor 16 is arranged at one of the lowering positions the same as the initial time, and sets the supply amount p in the normal direction, up The cloth W1 and the lower cloth w2 are the supply amount p in the normal supply direction marked by the arrow mark X. The needle is lowered at the suture point B for the fourth time and forms a node 4A of the perfect suture. In addition, the upper cloth W1 and the lower cloth W2 supply the supply amount p in the normal supply direction, and the needle is lowered a fifth time at a suture point c to form a node 5A of a perfect suture. When the counter counts the number of times the needle is lowered twice in the normal direction, the actuator 17 of the direct movement motor 16 is arranged at an upper position similar to the previous time to constitute a reverse feed. The upper cloth W1 and the lower cloth W2 are indicated by arrows. Mark the supply amount p in the reverse supply direction in the direction of y, the needle drops at the suture point B for the sixth time, and forms a node 6 A of the button stitching suture. Therefore, as shown in the suture point B and the suture point C in FIG. 4, according to the formed suture, two perfect sutures with a strong node force and a buckle suture are formed on a single suture point ( Same needle down position). In addition, there are three upper threads NS1, NS2, NS3, and lower threads US1, US2, and US3 in a suture interval of one pitch, thereby increasing the friction on the contact surfaces of the upper and lower fabrics wi and the lower and upper fabrics W2. force. Even when the seam position is turned as shown in FIG. 5, because the upper cloth wi and the lower cloth W2 are sewn together by this stitch, the contact surfaces of the sewing portions of the upper cloth W1 and the lower cloth W2 are not opened. . Although the initial stop of sewing is not performed according to the above-mentioned first embodiment, 0 continued pages (when the description page of the invention is insufficient, please note and use the continued page) 567261 发明, invention description level _ 义 # 顾 _ May be operated by An operation signal of the operator performs initial stop sewing. For example, 'In stop sewing at the beginning of sewing, after the cloth is fed with the same amount (pitch) in the opposite direction (X direction), the needle then descends at a stop sewing point to form a stitch, and then at the same pitch in the normal direction. The supply cloth 5 forms a stitch at the stitch point A. Further, the cloth 'is fed again at the same pitch in the opposite direction and a stitch is formed at the sewing stop point described above. Further, after completion of the initial stop stitching, the stitches of the first embodiment are formed. In addition, the sewing can be stopped at the end of the suture. And 'When, for example, a signal input to the 10 sewing machine control member is obtained through a dip switch setting, an initial stop sewing and a final stop can be automatically performed by a start signal and an end signal of the foot brake board. Sewing. As shown in the above embodiment, the number of times the stitches are lowered (the number of stitches) formed by the ordinary supply and the number of times the stitches are lowered (the number of stitches) formed by the reverse supply may be arbitrarily changed. For example, after four 15-pin lowerings with normal supply, a second needle lowering with reverse supply. Therefore, during the third needle drop and thereafter, two perfect sutures and a button stitch are formed at the respective needle drop points. And 'Although a configuration has been described in which the number of times the stitches of the cloth are stitched by ordinary supply is greater than the number of times that the stitches of the cloth 20 are stitched by reverse supply, according to the respective embodiments described above, on the contrary, The number of times the stitches to sew the cloth to the supply may be greater than the number of times the stitches to sew the cloth by the ordinary supply are lowered. And 'Although there is a continuous sewing machine, even when the same supply amount is set for the normal supply and the reverse supply, the actual supply amount will still be based on the supply of 0 pages. (When the invention description page is insufficient, please note and use (Continued) 18 567261 The shape of the retractor with slight differences can still constitute approximately the same needle drop point ', and the needle drop point can be regarded as remaining unchanged. Also, although according to the above-mentioned embodiment, a structure in which the cloth supply mechanism of the sewing machine is used as the cloth supply member to supply the upper cloth and the lower cloth 5 'may be replaced by a well-known X-Υ supply member. Therefore, a straight suture can be formed, and a suture of any shape can also be formed, such as a curved suture or a suture with continuous curves and straight lines. Furthermore, as for the nodes located on the upper line NS and the lower line us of the respective sewing points of the cloth, the button 10 suture can be arbitrarily formed by controlling the upper line NS, the lower line us, or the needle. In addition, in the case where the fastening stitches are not particularly required, a mechanism for preventing and fastening the fastening stitches can also be used to prevent the fastening stitches from being formed at the respective sewing points of the cloth, such as an on-axis A mechanism that rotates a needle bar and a shuttle in the thread direction to prevent the formation of a 15 stitch in a region in the feeding direction constituting the button stitching.

According to the present invention, the upper and lower cloths are sewn at each suture by a 10 locking suture of the fastening thread, and a plurality of nodes are formed at First, the respective needle drop points (stitch points), thus increasing the respective tensile strength of the upper line NS and the lower line US, and also increasing the friction of the upper line NS and the lower line US at the nodes in each stitch point. In addition, the upper line NS and the lower line US traverse the top and tail sides of the upper cloth W1 and the lower cloth 15 W2, and therefore, a large friction force is generated between the upper line NS and the lower line US and the upper cloth W1 and the lower cloth W2. . In addition, the strength of the tightening force is spread across a plurality of lines. As can be seen from the above, when the sewing part is opened, the elongation effect of the upper NS and the lower US can be reduced, and the deformation of the nodes of the upper NS and the lower US can be reduced, and the upper NS and the lower US can be greatly reduced.
