Field of the Invention The present invention relates to a method for suturing a belt, which is obtained by sewing a stretchable 5-belt such as rubber to an opening peripheral portion of a cylindrical material such as a briefs, a swimsuit or a pair of pants. C. In the prior art, the waist circumference of a cylindrical material such as a briefs or a sweatpants is shown in Japanese Patent Publication No. Sho 63-60679, Japanese Patent Application Laid-Open No. Hei. A typical prior art sewing machine for sewing a stretchable belt such as rubber at the peripheral portion of the opening such as the left or right thigh portion. Fig. 1 is a perspective view of a sewing machine 1 similar to the sewing machine shown in Japanese Patent No. 3735768. The sewing machine 1 of Fig. 10 is configured such that the sewing machine main body 8 as the overlock machine 15 has a belt supply mechanism 2 for supplying a belt such as a rubber tape T. The ribbon supply mechanism 2 includes a supply portion having a large roller 4 and a tabloid 5, and the large roller 4 is rotationally driven by the stepping motor 6 via the timing belt 7, and the small pro- 5 is elastically abutted against the large roller 4 to be driven to rotate. The tape supply mechanism 2 is provided above the needle plate 9, and a belt-shaped 20-feed device (not shown) is provided above the sewing machine 1. The belt feeding device freely rotates the shaft to support the reel in which the rubber tape T as a belt is wound, and the rubber T fed from the reel is sandwiched between the large roller 4 and the small roller 5 of the belt feeding mechanism 2, The rotation of the large roller 4 is driven by the needle plate 9 directed downward. The weight plate 10 is disposed on the needle plate 9, and the pressure iron 10 is provided with a tape guide opening u into which the rubber tape τ supplied from the belt-shaped 3 201000710 material supply mechanism 2 is inserted. The rubber band τ inserted into the belt guiding opening 11 is sent to the weight 1〇. Further, a transporting groove (not shown) extending in the transport direction A of the cloth (blank) is formed in the needle plate 9, and the transporting groove is disposed to be freely movable on the five faces of the needle plate 9. The conveying teeth are elliptical in the conveying direction in the conveying groove, whereby the blank sandwiched between the pressing plate 12 of the weight 10 and the needle plate 9 is sent out in the cloth conveying direction A. Further, a knife () (not shown) for cutting the conveyed blank to align the ends of the blank is provided on the side portion of the needle plate 9. When the rubber band τ is sewn, the operator sets the blank to the rubber tape T which is supplied to the tape guide opening 11 of the weight 10, and drives the sewing machine i to perform sewing. When the sewing machine 1 is driven, the side portion of the billet is conveyed while being cut by the blade device, and the rubber tape T is supplied, and the rubber tape T can be sewn along the end of the billet. And 'by the feed speed of the stepping motor 6 that supplies the rubber belt τ is slower than the conveyance speed of the blank, thereby imparting a certain tension to the rubber tape T from the roller 4' 5 to the needle drop position, and The rubber band T is sewn to the blank in a tensioned state. Thus, when the rubber tape T is sewn along the peripheral edge portion of the opening of the blank, and the sewing of the rubber tape τ is completed in one week of the peripheral portion of the opening, the blade device 3 disposed under the large light 4 20 and the small roller 5 is cut. Broken rubber band T. The operator performs this rubber sewing operation continuously. Fig. 11 shows an example of a pair of pants which are sewn to the peripheral edge portion of each opening by the sewing machine 1 described above. The state shown in the briefs 20 of Fig. 11 is a state in which the waistband portion (opening peripheral portion) 21, the rubber tape T is sewn, and the rubber 201000710 tape τ is cut, and the right and left thigh portions (opening peripheral portion) In the 22, 23, after the sewing of the rubber tape T and the cutting of the rubber tape τ, the cut end portion (the cutting head portion) is further cut off. The suture of the rubber band τ on the waist portion 21 is sewed while moving the trousers 20 of the barrel material, and the seam is formed in the three directions. When the sewn portion of the rubber band is subjected to one week, the rubber band is cut by the knife device 3 as described above. At the time of this cutting, as shown in the figure, the portion (hereinafter referred to as the cut end portion) Te which is cut after the end portion of the rubber tape which is sewn is left. The cut end Te is discarded after being cut. The length L of the cut end Te is usually about 4 cm, and in the sewing factory where the stitching 10 of a large number of briefs is performed, the actual amount of the discarded rubber band τ cannot be ignored, which causes the material cost to become high. And from the point of view of provincial resources, it is also expected to be fundamentally resolved. In the Japanese Laid-Open Patent Publication No. 63-60679, when the beginning end portion of the rubber band is close to the sewing position, the rubber band is cut and the pressing plate is operated, and the sewing is continued while the cutting action is applied to the cut end portion. The suture is attached to the culture material while the cut end is extended. When the end portion of the rubber tape is sutured in this manner, the cut portion to be discarded as described above is not generated, and the cut end portion is also sewn in a tensioned state. However, depending on the degree of adjustment of the braking force of the pressing plate, the tensioned state of the cut end portion is the same as the tension state of the other portion, and sometimes it is uncomfortable when worn on the body. Further, it is difficult to completely match the beginning end portion and the end portion of the rubber band, and product quality problems may occur depending on inconsistent tenants. & Further, in the Japanese Patent Publication No. 7_5147, the content of the 201000710 conveyance amount of the belt is changed by the rotation speed of the belt conveyance motor at the time of sewing, and the pleats are applied in any length of the blank. However, the rotational speed sound or the reverse rotation control of the belt conveyance motor in the Japanese Patent Publication No. Hei 7-51478 is only for the pleats, and is not for the treatment of the cut end portion of the belt. 5 and the content described in Japanese Patent No. 3735768 is: "Before the suturing of the rubber band is completed, the tape feeding mechanism is brought close to the sewing position, and then the rubber tape is cut and the cut end is directly sewn. On the culture, the so-called tension-free portion is thereby shortened. At this time, the cut end portion to be discarded is not generated, but it is inevitable that a few tension-free portions remain. In addition, the mechanism for bringing the tape supply mechanism disclosed in Japanese Patent No. 3735768 to the sewing position is moved by a belt which is moved up and down by the entire belt supply mechanism including a driving unit such as a stepping motor. The cylinder is constructed so that not only the device becomes large but also cannot be applied to an existing sewing machine. SUMMARY OF THE INVENTION 3 SUMMARY OF THE INVENTION An object of the present invention is to provide a method of stitching a belt, which can shorten the cut end of the belt in a simple manner. The present invention is a method for suturing a belt, and the belt 20 is sewn to the peripheral edge portion of the opening by supplying a stretchable belt to the peripheral edge portion of the opening of the tubular blank. The strip suture end portion that has reached the peripheral edge portion of the opening at the suture position is dry, and after the supply of the strip is stopped, the strip is given a tensile force in a direction opposite to the supply direction. The strip is cut in the vicinity of the suture end portion. 201000710 5
並且’在本發明中，優選上述供給停止後的對帶狀物 的拉伸力賦予’通過在使上述供給輥對停止後，使供給輥 對向與帶狀物的供給方向相反的方向旋轉來進行。 根據本發明的帶狀物的縫合方法，伸縮性的帶狀物一 邊通過供給輥對供給—邊順序地將帶狀物縫合在開口周緣 部上。此時，帶狀物在被施加了張力的狀態下在開口周緣 部的圓周方向上被縫合。並且，在上述縫合到達開口周緣 部的帶狀物縫合終端部時，在停止了上述帶狀物的供給之 後’在成爲對帶狀物賦予了與供給方向相反方向的拉伸力 10 15 的狀態的基礎上，在上述縫合終端部的附近切斷帶狀物， 因此在該切斷之前的狀態下，成爲帶狀物在縫合終端部和 供給輥對之間伸長的狀態，通過切斷而剩餘在縫合終端部 的成爲切斷頭部分的切斷端部收縮。該切斷端部被切除並 破廢棄，但由於收縮而變短，因此即使進行大量縫合，與 以往相比也顯著減少了帶狀物的廢棄量。Further, in the present invention, it is preferable that the stretching force of the belt member after the supply is stopped is performed by rotating the supply roller pair in a direction opposite to the supply direction of the belt after stopping the supply roller pair. get on. According to the stitching method of the belt of the present invention, the stretchable belt is sequentially sewn to the peripheral edge portion of the opening by the supply roller pair. At this time, the ribbon is sewn in the circumferential direction of the peripheral portion of the opening in a state where tension is applied. When the stitching reaches the tape stitching end portion of the peripheral edge portion of the opening, after the supply of the tape is stopped, the state in which the tensile force 10 15 is applied to the tape in the opposite direction to the supply direction is applied. In addition, the strip is cut in the vicinity of the suture end portion. Therefore, in the state before the cutting, the strip is stretched between the suture end portion and the pair of supply rollers, and is left by cutting. The cut end portion of the sewn end portion which is the cut head portion is shrunk. Since the cut end portion is cut off and discarded, it is shortened by shrinkage. Therefore, even if a large amount of stitching is performed, the amount of waste of the strip is remarkably reduced as compared with the prior art.

37-axis support in the _ machine. The 7 of the weight 37 is turned into a t-shaped (not Q) needle plate 36 by twisting yellow (see Fig. 2) 38, and a needle 39 (see Fig. 2) is formed. The conveying tooth extended by the square * is a detailed drawing of a tooth (not shown), and the two needles 39 of the plate 36 are reciprocated in the upper and lower steps of the needle transporting side Jr" The material on the plate 36 is conveyed in the cloth transport direction A. Further, in the vicinity of the upstream side (second_right side) of the cloth transport tree of the weight 37, a knife device 40 that cuts and aligns the edge of the conveyed (four) is provided ( Referring to Fig. 2), a belt feeding machine is attached to the front side of the sewing machine main body 3! The belt feeding mechanism 32 has a supply roller pair (large roller view 51) and a knife A supply unit 53 composed of the device 52 and a stepping motor 55 as a drive source. The rubber supply is provided above the tape supply mechanism 32 to the supply roller pair 5A, 51 (four) conveying device (not shown). The rubber belt τ is supplied to the needle drop position by the conveyance action of the above-described supply (four) 50, 51. Fig. 2 is a side view of the belt supply mechanism 32. 3 is a schematic cross-sectional view taken along line 切断·ΠΙ of Fig. 2. The stepping motor is held on the motor mounting table 60, and the motor mounting table 60 is attached to the roller mounting table 61 (Figs. 2 and 3). In the middle, the timing pulley is fixed on the output shaft of the stepping motor 55, and the timing pulley (none of which is shown) is rotated by the timing belt. The timing belt 20 201000710 The wheel passes through the shaft (not shown) and the large roller 50 Thereby, the large roller 5 is rotated by the stepping motor 55. The small roller 51 is axially supported by the roller chain 62, and elastically abuts against the large roller 5A via the knitting (not shown). The operator presses the presser bar (not shown) coupled to the key 62, and the roller chain 62 is pulled to the front, and the small roller 51 can be separated from the large roller 5〇. Therefore, when the rubber tape T is set, In a state where the small roller 51 is separated, the rubber tape T is inserted into the gap with the large roller 50, and the small roller 51 is returned to the original position. The outer circumferential surfaces of the large roller 50 and the small roller 51 are knurled, so that approximately 50 And the small roller 51 can reliably hold the rubber tape T. And, when the motor 55 is pulled in by step 1, the large roller 50 is made At the time of the drive, the small roller 51 is driven to rotate, and the rubber tape T held by the large spokes 50 and the small rollers 51 is fed downward. On the roller device mounting table 61 of the tape supply mechanism 32, the passing light is provided. A sensor 56 is realized by an optical detector such as an interrupter. A reflection plate 57 is mounted near the upstream side of the cloth conveyance direction A of the needle plate 36. The reflection plate 57 is constituted by 15 which is located at the slave tape sensor 56. The light path of the light emitted from the light-emitting element 56a is directed to the light-receiving element 56b of the belt sensor 56. A knife device 52 is attached directly below the large roller 50 and the small roller 51. The knife device 52 is fixed by the knife 52A and movable The knife 52B is configured, and the rubber tape T is fed out through the middle thereof, and when the sewing is completed, the rubber 20 tape T can be cut by operating the movable blade 52B. The movable blade 52B is driven by a cylinder (not shown). A belt guiding opening 41 is formed in the weight 37, and the rubber tape T fed by the blade unit 52 is inserted into the tape guiding opening 41 and guided to the lower surface of the weight 37. In the sewing machine 30 configured as described above, when the rubber tape T is sewn in the circumferential direction of the opening peripheral portion of the briefs 70, which is a tubular material of the suture object as shown in Fig. 6, for example, the waist portion 10 201000710 71 The rubber band is fed to the tape guiding opening 41 while the weight 37 is raised, and the waist portion 71 is placed in the cylinder of the slitting machine body 31 in such a manner that a part of the briefs 7 is positioned below the belt. On the base portion 35. In addition, in the second and third figures, the illustration of the cylinder base portion 35 is omitted, but the briefcase is placed on the cylinder base portion 35, and the waist portion 71 of the briefs 70 is held by the needle plate 36. When the conveyance tooth (not shown) that is operated by a drive source (not shown) is operated between the weight and the weight 37, the briefs 70 are alternately wound in the cloth conveyance direction. In synchronization with the cloth conveyance operation, the needle 39 starts to reciprocate up and down, and the supply of the 10 roller pairs 50, 51 is performed, and the tape T is guided to the lower surface of the weight 37, and the rubber tape T is sewn to the waist portion 71 of the briefs 7A. At this time, the knife device 4A is also in the cut state, and the edge 74 of the fed briefs 70 is cut and aligned. The supply speed of the rubber band τ is made slightly smaller than the cloth feed speed, whereby the rubber band τ is sewn to the waist portion 71 of the briefs 70 with tension. 15 In the stitching of the rubber band, the briefs 70 are cut by the blade device 40 in order to align the end of the blank, and are conveyed by the blank guide 70 to the blank end 70 while being conveyed together with the belt τ. The reflecting plate 57 with the sensor % is disposed on the upper end portion of the front end portion of the blank guide G, so that the field of the pants 70 is not detected and 70 Ε is detected, and the stitching start end portion 8 of the tape is detected. When the sewing of the rubber tape τ 2〇 proceeds, and the stitched end of the rubber tape 7 is wound around the one end and the stitching start end portion Ts passes over the reflecting plate 57, the light receiving element 56b does not receive the reflected light from the light emitting element 56a. When it is detected that the light-receiving element 56b does not receive the reflected light, the time from the start end portion Ts of the rubber tape τ to the above-described tape guide opening 41 is calculated, and the stop of the cloth conveyance and the stop of the supply roller pair 5A, 51 are performed. 11 201000710 That is, when the suture start end portion Ts reaches the strip guide opening 41, it becomes a suture end portion. Thereafter, the stepping motor 55 is reversed, and the large roller 5〇 is also reversed, and the rubber tape T which is lost by the large roller 50 and the small roller 51 is given a tensile force. The briefs 7 are held together with the stitched rubber band T by the needle plate 36 and the weight 37, so that the rubber tape T is stretched in the opposite direction to the feeding direction, and the kneading pair 50 is supplied to the holding portion. 51 is in an extended state. In the extended state, the blade device 52 operates 'the rubber band T is cut. Fig. 4 shows a normal sewing state, and Fig. 5 shows a state in which the rubber tape T is cut after the sewing is completed. Fig. 6 shows an example of a pair of pants which are sewn to the peripheral edge portion of each opening 10 by the sewing machine 30 described above. The state shown in the briefs 7 of Fig. 6 is the state in which the suture of the rubber band T and the state of the rubber band τ are cut off on the waist portion 71, on the right and left thigh portions 72, 73, and the rubber band T. After the sewing and the cutting of the rubber tape T, the state of the cut end portion (the cut head portion) is further cut off. The stitching of the rubber band τ on the waist portion 71 is performed by moving the three-pronged pants 70 as a cylindrical shape while moving, and the stitching is performed in the a direction. When the sewn portion of the rubber tape T is one week, the rubber tape τ is cut by the blade device 52 as described above. At the time of this cutting, as shown in the figure, the cut end Te of the rubber tape T remains on the end portion of the stitching, and then the cut end Te is cut and discarded. The cut end portion Te is cut in the above-described extended state 20. Therefore, the cut end portion Te is shrunk after the cutting, and the length Ls is significantly shortened from the length L of the case of Fig. 11. Therefore, the amount of the rubber band τ to be cut and discarded is reduced. In the sewing factory where a large number of stitching processes are performed, resources can be effectively saved and costs can be reduced. Figure 7 is a control block diagram of the sewing machine 3〇. The sewing machine 3 is controlled by the control unit 12 201000710 (control circuit) 63 to control the rotary cutter motor material of the slitter, the stepping motor 55 of the ribbon supply mechanism Μ, and the movable knife drive cylinder of the knife device 52 of the rubber band T (not shown). And the knife device that is aligned with the edge of the cutting material is cut. The control unit performs these controls on the No. 4 to the 84th of the heart. The signal Si~s3 «The pedal 65 is operated by the operator's foot down. The signal Μ is before the k number, the signal S2 is the neutral money, the signal S3 is the rear stepping signal, and the signal S4 is the (4) presence or absence signal from the belt sensor 56. Then 'refer to the flow of Fig. 8 The timing chart of Fig. 9 and Fig. 9 shows the control operation of the slitting machine 30. The timing (4) in Fig. 9 indicates the state of the previous sewing operation and the next sewing operation. At time ti, the pedal 65 is stepped in (step ST1), and the control unit 踏 returns to the U-S3 in response to the pedal 而, and causes the weight 37 to rise, and in this state, the trousers 70 are taken out. And the next stitched blank 7 can be placed on the needle plate 36. At this time, stepping The motor 55 is rotated forward, and only a predetermined amount of rubber 15 tape T' rubber is inserted into the tape guide opening 41 (step ST2). When the blank 70 is set, the rubber band τ is inserted and the pre-position is mounted. Upon completion, the stepping of the pedal 65 is terminated at time t2 to return to the neutral position. The control unit 63 returns the weight 37 to the lowered position in response to the neutral signal S2 from the pedal 65, thereby on the needle plate 36, in the rubber When the belt τ is superposed on the blank 7 〇, the nip iron 37 is pressed from above. Next, at time t3, the operator steps the pedal 65 forward to the front stepping position (step ST3), and starts the sewing operation. The front depression signal S1 is input to the control unit 63, and the control unit 63 responds to the signal to rotate the sewing machine rotation motor 64, drives the sewing machine, and causes the stepping power 13 201000710 of the ribbon supply mechanism 32 to rotate forward (step ST4). Thereby, the rubber tape T is supplied with the blank 70 to 'sew the rubber tape on the blank 70 and is sent out. And, at this time, the knife device (the falling knife device (〆乂卜口 7 y)) is cut. Broken position, while the blank 7 is sent out The edge 74 of the portion 71 is cut and aligned. 5 Thus, the rubber tape T is sewn to the peripheral edge portion (waist portion) 71 of the opening of the blank 70, and when the sewing is completed, the tape sensor is applied as described above at time t4. 56 is turned on and the presence of the tape end is detected, and the signal material is input to the control unit 63 (step ST5). At this time, the knife device (dropper device) 4 is operated (step ST6) 'the knife device 40 is stopped for the blank 70 After that, at time t5, when the operator 10 stops the depression of the pedal 65, the rotation of the sewing machine rotation motor 64 and the stepping motor 55 is stopped, and the sewing operation of the rubber tape T is completed. At time t6, when the operator steps on the pedal 65 (step ST7), the control unit 63 responds to the signal and reverses the stepping motor 55. Thereby, the rubber tape T is stretched in the opposite direction to the supply direction (step 15 flash 8). At the same time, the thread cutting device (not shown) operates to cut the suture (step ST9). Then, the control unit 63 operates the blade device 52 to cut the rubber tape T that has been elongated by the pulling up, and causes the weight 37 to be raised (step ST10). By the cutting of the rubber tape T, the rubber band seaming of the pants 70 is completed, and in this state, the weight 37 is in the raised position, so that the stitched pants 7 as shown in Fig. 6 can be taken out. Then, when the operator stops the pedal 65 and returns to the neutral position at the time (step ST11), the control unit 63 responds to the neutral signal and causes the knife device 40 to be turned off (the blade device is reset) (step ST12), and the weight 37 is set to the lower position 201000710 10 15 20, and becomes the standby state of the next sewing operation. Thereafter, a new blank is set, and the operations of steps ST1 to ST12 are repeated, and the rubber belt τ is sewn to the waist portion 71 of the briefs 70. The sewing of the rubber band T of the right and left thigh portions 72, 73 of the briefs 7 is also performed in the same manner. In this way, as shown in Fig. 6, the cut end portion Te of the rubber band τ is greatly shortened as compared with the conventional case. Therefore, even if the sewing factory that performs a large number of stitching processes is scrapped, it is discarded. The amount of rubber band T has also been greatly reduced. Further, since the structure of the existing sewing machine 3 itself is not required to be changed, it can be implemented only by the change of the operating program, which is extremely beneficial to the user. In the above-described operation flow, the belt end detection (step (4) ST7 after the sensor is used as a trigger, and the belt pull-up (with conveyor motor reversal) in step ST8 and the subsequent steps (4) are performed as a trigger. The belt is cut by W, but the present invention is not limited thereto. For example, it is also possible to set the needle counting and discharging (4) to carry out the counting, and when the predetermined number of needles corresponding to the completion of the rubber sewing is counted, the step is sent to the threshold portion 63. The reverse signal of the motor 5 and the following (4) or the step == detection (with sensor on) signal S4 can also be used as a trigger, after the predetermined time of the letter is passed, the stepping motor _ 及 and the knife device are sent out. The operation signal of 52. The predetermined time for calculating the flute f is set by the time from the beginning of the belt ================================================================================ In the embodiment, the slit of the cut strip may also be an overlock machine. The description is cut, but the application 15 201000710 Also, after the stitching is completed, the strip is given a tensile force in the opposite direction to the supply direction. Method of making Although the supply roller has been described as an example of reverse rotation, a device for applying tension to the rubber tape (for example, five portions that are operated by a cylinder or the like) may be disposed between the supply roller pair and the sewing position, and may be sewn. After the completion, the device is operated. The tape sensor 56 is a sensor that detects whether or not the tape sewn on the peripheral edge portion of the opening of the blank passes, but may be a method of detecting the overlap state of the rubber tape with the rubber material. In this case, in the middle of the rubber sewing, only one layer of the rubber tape is superposed on the blank, and when the waist portion is surrounded by one week, the rubber 10 tape is in a state of overlapping two layers. Therefore, it is possible to use one layer of the rubber tape. It is judged whether or not the rubber tape stitching is completed by the difference in the amount of received light and the amount of light received when the two layers are overlapped. With this blank sensor, even if the operator does not operate, the rubber stitching can be automatically judged and the rubber tape can be pulled. The sensor 56 is not limited to the illustrated photo-interrupter type sensor, and may be other types of sensors. Moreover, the ribbon is not limited to a rubber band. The present invention can be implemented in various other manners without departing from the spirit or main features thereof. Therefore, the above-described embodiments are merely exemplified at any point, and the scope of the present invention is in the scope of patent claims. The contents of the description are not subject to any restrictions on the text of the specification, and all variations or modifications belonging to the scope of patent claims are within the scope of the invention.
