Description
本發明涉及一種帶狀物的縫合方法，將橡膠等伸縮性帶狀物縫合到三角褲、泳衣或運動褲等筒狀坯料的開口周緣部上。The present invention relates to a method for sewing a belt, which is obtained by sewing a stretchable belt such as rubber onto an opening peripheral portion of a cylindrical material such as a briefs, a swimsuit or a pair of pants.
在日本特公昭63-60679號公報、日本特開平7-51478號公報及日本專利第3735768號公報中，示出用於向三角褲或運動褲等筒狀坯料的腰圍部或左右大腿部等開口周緣部縫合橡膠等伸縮性帶狀物的縫紉機的典型現有技術。第10圖是與日本專利第3735768號公報中示出的縫紉機相同的縫紉機1的立體圖。第10圖的縫紉機1構成爲，在作爲包縫機的縫紉機主體8上具有供給橡膠帶T等帶狀物的帶狀物供給機構2。帶狀物供給機構2包括具有大輥4和小輥5的供給部，大輥4通過步進電動機6經由同步帶7而旋轉驅動，小輥5與大輥4彈性抵接而從動旋轉。這種帶狀物供給機構2設置在針板9的上方，並且在縫紉機1的上方設有未圖示的帶狀物送入裝置。該帶狀物送入裝置自由旋轉地軸支援捲繞了作爲帶狀物的橡膠帶T的卷軸，從卷軸送出的橡膠T夾在帶狀物供給機構2的大輥4和小輥5之間，並通過大輥4的旋轉驅動而被朝向下方的針板9供給。In the case of a tubular body such as a briefs or a sweatpants, the waist portion or the left and right thighs are shown in the Japanese Patent Publication No. Sho 63-60679, the Japanese Patent Publication No. Hei 7-51478, and the Japanese Patent No. 3735768. A typical prior art sewing machine for sewing a stretchable belt such as rubber at the periphery of the opening. Fig. 10 is a perspective view of the 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 a belt supply mechanism 2 that supplies a belt such as a rubber tape T is provided on a sewing machine main body 8 as an overlock machine. The ribbon supply mechanism 2 includes a supply portion having a large roller 4 and a small roller 5, and the large roller 4 is rotationally driven by the stepping motor 6 via the timing belt 7, and the small roller 5 is elastically abutted against the large roller 4 to be driven to rotate. This tape supply mechanism 2 is provided above the needle plate 9, and a tape feeding 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.
在針板9上配置有壓鐵10，在該壓鐵10上設有供從帶狀物供給機構2供給的橡膠帶T***的帶狀物引導口11。***到該帶狀物引導口11中的橡膠帶T被送到壓鐵10之下。The weight plate 10 is disposed on the needle plate 9, and the pressure iron 10 is provided with a tape guide opening 11 into which the rubber tape T supplied from the tape supply mechanism 2 is inserted. The rubber tape T inserted into the tape guiding opening 11 is sent under the weight 10.
並且，在針板9上形成有在布(坯料)的輸送方向A上延伸的輸送槽(未圖示)，在該輸送槽中配置有能夠在針板9上面上自由出沒的輸送齒，該輸送齒在輸送槽內沿布輸送方向進行橢圓運動，由此將夾在壓鐵10的壓板12和針板9之間的坯料向布輸送方向A送出。並且，在針板9的側部設置有將被輸送的坯料切斷而將坯料的端對齊的刀()裝置(未圖示)。Further, a transporting groove (not shown) extending in the transport direction A of the cloth (blank) is formed in the needle plate 9, and a transporting tooth that can freely float on the upper surface of the needle plate 9 is disposed in the transporting groove. The conveying teeth are elliptically moved in the conveying direction in the conveying direction, whereby the billet 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 blade that cuts the conveyed blank to align the ends of the blank is provided on the side portion of the needle plate 9 ( ) device (not shown).
在縫裝橡膠帶T時，操作員將坯料設置到被供給到壓鐵10的帶狀物引導口11中的橡膠帶T之下，驅動縫紉機1而進行縫合。當驅動縫紉機1時，坯料的側部一邊被刀裝置切斷一邊被輸送，並且橡膠帶T被供給，能夠沿著坯料的端來縫裝橡膠帶T。並且，通過使供給橡膠帶T的步進電動機6的輸送速度比坯料的輸送速度慢，由此對從輥4、5到落針位置之間的橡膠帶T賦予一定的張力，並在張緊狀態下將橡膠帶T縫裝在坯料上。When the rubber tape T 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 1 to perform sewing. When the sewing machine 1 is driven, the side portion of the blank 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 blank. Further, by making the conveying speed of the stepping motor 6 feeding the rubber tape T slower than the conveying speed of the blank, a certain tension is applied to the rubber tape T from the rollers 4, 5 to the needle dropping position, and tension is applied. The rubber tape T is sewn to the blank in the state.
這樣，當沿著坯料的開口周緣部縫裝橡膠帶T，並在開口周緣部的一周完成橡膠帶T的縫裝時，通過配置在大輥4和小輥5之下的刀裝置3切斷橡膠帶T。操作員連續進行這種橡膠縫合作業。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 T is completed in one week of the peripheral edge portion of the blank, the cutter device 3 disposed under the large roller 4 and the small roller 5 is cut. Rubber belt T. The operator performs this rubber sewing operation continuously.
第11圖表示通過上述的縫紉機1將橡膠帶T縫裝在各開口周緣部的三角褲的例子。在第11圖的三角褲20中表示的狀態爲：在腰圍部(開口周緣部)21上、橡膠帶T的縫合及橡膠帶T的切斷後的狀態，在左右大腿部(開口周緣部)22、23上、在橡膠帶T的縫合及橡膠帶T的切斷後進一步切除了切斷端部(切斷頭部分)的狀態。腰圍部21上的橡膠帶T的縫合是一邊使筒裝坯料的三角褲20迴圈移動一邊進行縫合，結果接縫沿a方向形成。當橡膠帶T的縫合部進行一周時，如上所述地通過刀裝置3切斷橡膠帶T。在該切斷時，如圖所示，在橡膠帶T的被縫合的終端部剩餘之後被切斷的部分(以下稱切斷端部)Te。切斷端部Te在切除後被廢棄。切斷端部Te的長度L通常有4cm左右，在進行大量三角褲20的縫合處理的縫合工廠，實際情況是廢棄的橡膠帶T的量不能無視，其成爲材料成本變高的原因，而且從省資源的觀點來看也期望從根本上解決。Fig. 11 shows an example of a pair of pants in which the rubber tape T is 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 rubber band T is sewn and the rubber tape T is cut in the waist portion (opening peripheral portion) 21, and the right and left thigh portions (opening peripheral portion) On the 22nd and 23rd, after the sewing of the rubber tape T and the cutting of the rubber tape T, the state of the cut end portion (the cutting head portion) is further cut off. The stitching of the rubber tape T on the waist portion 21 is performed by sewing the pants 20 of the package blank while moving, and the seam is formed in the a direction. When the sewn portion of the rubber tape T is subjected to one week, the rubber tape T 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 that is cut after the end portion of the rubber tape T that has been sewn remains. 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 a large number of pants 20 are sewn, the actual amount of the discarded rubber tape T 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.
在日本特開昭63-60679號公報中，當橡膠帶的始端部接近縫合位置時，將橡膠帶切斷並使按壓板動作，在對切斷端部賦予刹車作用的狀態下繼續縫合，在拉伸了切斷端部的狀態下縫裝在坯料上。如果這樣縫合處理橡膠帶的終端部，則不產生上述那樣的應廢棄的切斷端部，切斷端部也在張緊狀態下被縫裝。但是，根據按壓板的刹車力的調整程度，切斷端部的張緊狀態和其他部分的張緊狀態不同，穿著在身體上時有時感覺不舒服。並且，難以使橡膠帶的縫合始端部和終端部完全一致，而根據不一致的程度可能出現商品質量問題。In Japanese Laid-Open Patent Publication No. SHO-63-60679, when the beginning end portion of the rubber band approaches the sewing position, the rubber band is cut and the pressing plate is operated, and the sewing is continued while the cutting end portion is given a braking action. The material is sewn to the blank in a state where the cut end portion is stretched. When the end portion of the rubber tape is sutured in this manner, the cut end 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 tension state of the cut end portion is different from the tension state of other portions, and sometimes it is uncomfortable when worn on the body. Moreover, it is difficult to completely match the beginning end portion and the end portion of the rubber band, and the quality of the product may occur depending on the degree of inconsistency.
並且，在日本特開平7-51478號公報中記載的內容爲：在縫合時通過使帶輸送電動機的轉速變小或反轉而使帶的輸送量變化，在坯料的任意長度範圍內施加褶襇。但是，日本特開平7-51478號公報中的帶輸送電動機的旋轉速度或反轉控制，只是爲褶襇而進行的，並不是爲了進行帶的切斷端部的處理。In the case of the sewing machine, the amount of conveyance of the belt is changed by changing the rotation speed of the belt conveyance motor at the time of sewing, and pleating is applied to any length of the blank. . However, the rotation speed 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.
並且，在日本專利第3735768號公報中記載的內容爲：在橡膠帶的縫合完成之前，使帶狀物供給機構接近縫合位置，之後切斷橡膠帶，並將切斷端部直接縫裝在坯料上，由此使所謂無張力部分變短。此時，不產生應廢棄的切斷端部，但不可避免要剩餘若干無張力部分。並且，用於使日本專利第3735768號公報所公開的帶狀物供給機構接近縫合位置的機構，由使包括步進電動機等驅動部的帶狀物供給機構整體上下動的帶狀物供給移動缸構成，爲此不僅裝置變大而且無法適用於已有的縫紉機中。Further, in Japanese Patent No. 3735768, the tape feeding mechanism is brought close to the sewing position before the sewing of the rubber tape is completed, and then the rubber tape is cut and the cut end is directly sewn to the blank. On the top, 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. Further, the mechanism for bringing the tape supply mechanism disclosed in Japanese Patent No. 3735768 to the sewing position is supplied to the moving cylinder by a belt which is moved up and down by the entire belt feeding mechanism including the driving unit such as a stepping motor. In this case, not only the device becomes large but also cannot be applied to an existing sewing machine.
本發明的目的是提供一種帶狀物的縫合方法，能夠以簡單的方法來縮短帶狀物的切斷端部。It is an object of the present invention to provide a method of stitching a belt which can shorten the cut end of the belt in a simple manner.
本發明是一種帶狀物的縫合方法，一邊通過供給輥對向筒狀坯料的開口周緣部供給伸縮性的帶狀物，一邊將帶狀物縫合在上述開口周緣部上，其特徵在於，在上述縫合位置達到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，在對帶狀物賦予了與供給方向相反方向的拉伸力的狀態下，在上述縫合終端部的附近切斷帶狀物。The present invention relates to a method of sewing a belt, which is characterized in that, by supplying a stretchable belt to a peripheral edge portion of the opening of the cylindrical material by a supply roller, the belt is sewn to the peripheral edge portion of the opening. When the stitching position reaches the tape stitching end portion of the peripheral edge portion of the opening, after the supply of the tape is stopped, the tape is given a tensile force in a direction opposite to the supply direction, and the stitching is performed. The strip is cut in the vicinity of the terminal portion.
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。Further, in the present invention, it is preferable that the tensile force is applied to the belt after the supply is stopped, and after the supply roller pair is stopped, the supply roller is rotated in a direction opposite to the supply direction of the belt. get on.
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一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被廢棄，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。According to the sewing method of the belt according to the present invention, the stretchable belt is sequentially sewn to the peripheral edge portion of the opening while being supplied by the supply roller pair. At this time, the tape is sewn in the circumferential direction of the peripheral portion of the opening in a state where tension is applied. In addition, 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 base material is provided with a tensile force in a direction opposite to the supply direction. In the state in which the tape is cut in the vicinity of the stitching end portion, the tape is stretched between the stitching end portion and the pair of supply rollers in the state before the cutting, and the stitching remains in the stitching. The cut end portion of the end portion that is the cut head portion contracts. Since the cut end portion is cut and discarded, it is shortened by shrinkage, so that even if a large amount of stitching is performed, the amount of waste of the strip is remarkably reduced as compared with the related art.
並且，如果上述供給停止後的對帶狀物的拉伸力的賦予，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，則能夠簡單且有效地進行拉伸力的賦予。並且，能夠成爲如下構成：對於已有的縫紉機，不需要任何設計變更而只通過變更動作程式就能夠執行縮短帶狀物的切斷端部的處理，因此對於使用已有縫紉機的用戶來說極其有益。When the supply of the supply roller is stopped, the supply roller is rotated in a direction opposite to the supply direction of the ribbon, and the supply of the tensile force to the belt after the supply is stopped is performed. The imparting of the tensile force is carried out simply and efficiently. Further, in the conventional sewing machine, it is possible to perform the process of shortening the cut end portion of the belt by merely changing the operation program without any design change, and thus it is extremely difficult for the user who uses the existing sewing machine. Good.

以下參照附圖對本發明的優選實施方式進行詳細說明。Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
第1圖是使用作爲本發明一個實施方式的帶狀物的縫合方法的縫紉機30的立體圖。縫紉機30是在作爲扁平縫縫紉機的縫紉機主體31上安裝帶狀物供給機構32而構成的，在本實施方式中作爲伸縮性的帶狀物而供給橡膠帶T，例如在進行三角褲和運動褲等的腰圍部或大腿部等開口周緣部的橡膠縫裝的情況下使用。Fig. 1 is a perspective view of a sewing machine 30 using a sewing method of a belt as an embodiment of the present invention. The sewing machine 30 is configured by attaching a tape supply mechanism 32 to the sewing machine main body 31 as a flat sewing machine. In the present embodiment, the rubber tape T is supplied as a stretchable belt, for example, in briefs and sweat pants. It is used when the rubber is sewn in the peripheral portion of the opening such as the waist portion or the thigh portion.
在縫紉機主體31的缸底座部35上水平地配置有針板36，在針板36上配置有壓鐵37。該壓鐵37軸支援在縫紉機主體31上，並且壓鐵37通過扭簧(參照第2圖)38而被向下方施力。在壓鐵37之下的針板36上，形成有針39(參照第2圖)插通的落針部(未圖示)、及在布(坯料)輸送方向A上延伸的輸送槽(未圖示)，在該輸送槽內設置有輸送齒(未圖示)，該輸送齒在輸送槽內與針39的上下往復運動同步地進行在針板36的上面上自由出沒的橢圓運動，將針板36上的坯料沿布輸送方向A輸送。並且，在壓鐵37的布輸送方向A上游側(第2圖的右側)附近，設置將所輸送的坯料的緣切斷而對齊的刀裝置40(參照第2圖)。A needle plate 36 is horizontally disposed on the cylinder base portion 35 of the sewing machine main body 31, and a weight 37 is disposed on the needle plate 36. The weight 37 shaft is supported by the sewing machine main body 31, and the weight 37 is biased downward by a torsion spring (refer to FIG. 2) 38. A needle drop portion (not shown) through which the needle 39 (see FIG. 2) is inserted and a transport groove extending in the cloth (blank) transport direction A are formed on the needle plate 36 below the weight 37 (not shown). As shown in the figure, a transporting tooth (not shown) is provided in the transporting groove, and the transporting tooth moves in an elliptical motion freely on the upper surface of the needle plate 36 in synchronization with the vertical reciprocation of the needle 39 in the transporting groove. The blank on the needle plate 36 is conveyed in the cloth conveying direction A. Further, in the vicinity of the upstream side (the right side in FIG. 2) of the cloth conveyance direction A of the weight 37, the blade device 40 which cuts and aligns the edge of the conveyed material is provided (refer FIG. 2).
在縫紉機主體31的前面安裝有帶狀物供給機構32。帶狀物供給機構32具有：由帶狀物的供給輥對(大輥50及小輥51)及刀裝置52構成的供給部53；和作爲驅動源的步進電動機55。在帶狀物供給機構32的上方設置有將橡膠帶T向供給輥對50、51供給的帶輸送裝置(未圖示)，通過上述供給輥對50、51的輸送作用，橡膠帶T被向落針位置供給。A tape supply mechanism 32 is attached to the front surface of the sewing machine main body 31. The tape supply mechanism 32 has a supply portion 53 composed of a supply roller pair (large roller 50 and small roller 51) and a blade device 52, and a stepping motor 55 as a drive source. A belt conveying device (not shown) for supplying the rubber tape T to the supply roller pairs 50 and 51 is provided above the tape supply mechanism 32, and the rubber tape T is guided by the conveying action of the supply roller pairs 50 and 51. The needle drop position is supplied.
第2圖是帶狀物供給機構32的側視圖。第3圖是從第2圖的切斷面線III-III看的概略剖視圖。步進電動機55被保持在電動機安裝台60上，電動機安裝台60安裝在輥裝置安裝台61(第2及3圖中省略)上。在步進電動機55的輸出軸上固定有同步帶輪，通過同步帶使同步帶輪(均未圖示)旋轉。同步帶輪通過軸(未圖示)與大輥50連結。由此，通過步進電動機55能夠旋轉驅動大輥50。小輥51軸支援在輥鏈62上，並經由扭簧(未圖示)與大輥50彈性抵接。並且，操作員通過按壓與輥鏈62連結的輥壓杆(未圖示)，輥鏈62被拉起到面前，能夠使小輥51從大輥50離開。因此，在設置橡膠帶T時，在使小輥51離開的狀態下，將橡膠帶T***與大輥50的間隙，並將小輥51返回原位。FIG. 2 is a side view of the ribbon supply mechanism 32. Fig. 3 is a schematic cross-sectional view as seen from the cut surface line III-III of Fig. 2 . The stepping motor 55 is held on the motor mounting table 60, and the motor mounting table 60 is attached to the roller device mounting table 61 (omitted in Figs. 2 and 3). A timing pulley is fixed to 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 pulley is coupled to the large roller 50 via a shaft (not shown). Thereby, the large roller 50 can be rotationally driven by the stepping motor 55. The small roller 51 is axially supported by the roller chain 62, and elastically abuts against the large roller 50 via a torsion spring (not shown). Further, the operator presses the roller bar (not shown) coupled to the roller chain 62 to pull the roller chain 62 forward, and the small roller 51 can be separated from the large roller 50. Therefore, when the rubber tape T is set, the rubber tape T is inserted into the gap with the large roller 50 in a state where the small roller 51 is separated, and the small roller 51 is returned to the original position.
大輥50及小輥51的外周面進行了滾花加工，因此通過大輥50和小輥51能夠可靠地夾持橡膠帶T。並且，當通過步進電動機55使大輥50旋轉驅動時，小輥51從動旋轉，由大輥50和小輥51夾持的橡膠帶T被向下方送出。Since the outer peripheral surfaces of the large roller 50 and the small roller 51 are knurled, the rubber tape T can be reliably held by the large roller 50 and the small roller 51. When the large roller 50 is rotationally driven by the stepping motor 55, the small roller 51 is driven to rotate, and the rubber tape T held by the large roller 50 and the small roller 51 is fed downward.
在帶狀物供給機構32的輥裝置安裝台61上，設置有通過光斷續器等光學檢測器實現的帶感測器56。在針板36的布輸送方向A的上游側附近安裝有反射板57。反射板57構成爲，其位於從帶感測器56的發光元件56a發出的光的光路上，其反射光指向帶感測器56的受光元件56b。On the roller device mounting table 61 of the tape supply mechanism 32, a tape sensor 56 realized by an optical detector such as a photointerrupter is provided. A reflection plate 57 is attached to the upstream side of the cloth sheet conveyance direction A of the needle plate 36. The reflecting plate 57 is configured such that it is located on the optical path of the light emitted from the light-emitting element 56a of the sensor 56, and the reflected light is directed to the light-receiving element 56b of the band sensor 56.
在大輥50和小輥51的正下方安裝有刀裝置52。刀裝置52由固定刀52A和活動刀52B構成，橡膠帶T通過其中間地被送出，在縫合完成時，通過使活動刀52B動作能夠切斷橡膠帶T。活動刀52B由缸(未圖示)驅動。在壓鐵37上形成有帶狀物引導口41，通過刀裝置52而送出的橡膠帶T***帶狀物引導口41，並被引導到壓鐵37的下面。A knife device 52 is attached directly below the large roller 50 and the small roller 51. The knife device 52 is composed of a fixed blade 52A and a movable blade 52B, and the rubber tape T is fed out through the middle thereof, and when the sewing is completed, the rubber 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 knife device 52 is inserted into the belt guiding opening 41 and guided to the lower surface of the weight 37.
在如此構成的縫紉機30中，在對如第6圖所示那樣的縫合物件的筒狀坯料即三角褲70的開口周緣部、例如腰圍部71，沿其圓周方向縫合橡膠帶T時，在使壓鐵37上升的同時將橡膠帶T供給至帶狀物引導口41，並以三角褲70的一部分位於該帶T之下的方式將腰圍部71設置在縫紉機主體31的缸底座部35上。另外，在第2及3圖中省略了缸底座部35的圖示，但表示了將三角褲70設置在缸底座部35上的狀態，三角褲70的腰圍部71被夾持在針板36和壓鐵37之間。並且，當通過未圖示的驅動源進行動作的上述輸送齒(未圖示)動作時，三角褲70以在布輸送方向A上迴圈的方式被輸送。與該布輸送動作同步、針39開始上下往復動作，並且供給輥對50、51動作，帶T被引導到壓鐵37的下面，在三角褲70的腰圍部71上縫合橡膠帶T。此時，刀裝置40也爲切斷狀態，將所輸送的三角褲70的緣74切斷而對齊。使橡膠帶T的供給速度比布輸送速度稍小，由此橡膠帶T在具有張力的狀態下被縫合到三角褲70的腰圍部71上。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, that is, the waist pants 71, which is a cylindrical material as shown in Fig. 6, The rubber band T is supplied to the tape guide opening 41 while the weight 37 is raised, and the waist portion 71 is provided on the cylinder base portion 35 of the sewing machine main body 31 such that a part of the briefs 70 is positioned below the belt T. In addition, in the second and third figures, the illustration of the cylinder base portion 35 is omitted, but the briefcase 70 is placed on the cylinder base portion 35, and the waist portion 71 of the briefs 70 is held by the needle plate 36. Between the pressure iron 37. Further, when the transporting teeth (not shown) that are operated by a drive source (not shown) are operated, the briefs 70 are transported in a loop in the cloth transport direction A. In synchronization with the cloth conveyance operation, the needle 39 starts to reciprocate up and down, and the supply roller pairs 50, 51 operate, 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 70. At this time, the blade device 40 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 tape T is made slightly smaller than the cloth conveyance speed, whereby the rubber tape T is sewn to the waist portion 71 of the briefs 70 with the tension.
在橡膠帶T的縫合中，三角褲70爲了將坯料端對齊而通過刀裝置40切斷儘量少的寬度，並一邊通過坯料導向器G導向坯料端70E一邊與帶T一同被輸送。帶感測器56的反射板57設置在坯料導向器G的前端部上面上，因此不檢測三角褲70的坯料端70E，而檢測帶的縫合始端部Ts。當橡膠帶T的縫合進行、橡膠帶T的縫合端圍繞一周而縫合始端部Ts通過反射板57之上時，受光元件56b接受不到來自發光元件56a的反射光。從檢測到受光元件56b接受不到反射光開始，計算橡膠帶T的縫合始端部Ts到達上述帶狀物引導口41的時間，並進行布輸送的停止及供給輥對50、51的停止。即，當縫合始端部Ts到達帶狀物引導口41時，成爲縫合終端部。之後，步進電動機55反轉，隨此大輥50也反轉，由大輥50和小輥51夾持的橡膠帶T被賦予拉伸力。三角褲70與縫合完成的橡膠帶T一起被針板36和壓鐵37夾持，因此橡膠帶T被向供給方向的相反方向拉伸，在該夾持部分和供給輥對50、51之間成爲伸長的狀態。在該伸長的狀態下刀裝置52動作，橡膠帶T被切斷。第4圖表示通常的縫合狀態，第5圖表示縫合完成後將橡膠帶T切斷的狀態。In the stitching of the rubber tape T, the briefs 70 are cut by the blade device 40 in order to align the ends of the blanks, and are conveyed together with the tape T while being guided to the blank end 70E by the blank guide G. The reflecting plate 57 with the sensor 56 is disposed on the upper end portion of the front end portion of the blank guide G, so that the blank end 70E of the briefs 70 is not detected, and the stitching start end portion Ts of the belt is detected. When the stitching of the rubber tape T is performed and the stitched end of the rubber tape T 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 T reaching the tape guide opening 41 is calculated, and the stop of the cloth conveyance and the stop of the supply roller pairs 50, 51 are performed. 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 as the large roller 50 is also reversed, the rubber tape T held by the large roller 50 and the small roller 51 is given a tensile force. The briefs 70 are held together with the stitched rubber tape 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 between the holding portion and the pair of supply rollers 50, 51. Become in an extended state. In this extended state, the blade device 52 operates, and the rubber tape 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.
第6圖表示通過上述縫紉機30將橡膠帶T縫裝到各開口周緣部上的三角褲的例子。在第6圖的三角褲70中表示的狀態爲，在腰圍部71上、橡膠帶T的縫合及橡膠帶T的切斷後的狀態，在左右大腿部72、73上、橡膠帶T的縫合及橡膠帶T的切斷後進一步切除了切斷端部(切斷頭部分)的狀態。在腰圍部71上的橡膠帶T的縫合，是一邊使作爲筒狀坯料的三角褲70迴圈移動一邊進行縫合，結果縫合沿著a方向進行。Fig. 6 shows an example of a pair of pants which are sewn to the peripheral edge portion of each opening by the sewing machine 30 described above. The state shown in the briefs 70 of Fig. 6 is the sewing of the rubber band T on the waist portion 71, the sewing of the rubber tape T, and the cutting of the rubber tape T, on the left and right thigh portions 72, 73, and the rubber tape T. After the cutting of the rubber tape T, the state of the cut end portion (the cut head portion) is further cut off. The suture of the rubber band T on the waist portion 71 is performed while the briefs 70 as the cylindrical material are moved in a loop, and the stitching is performed in the a direction.
當橡膠帶T的縫合部成爲一周時，如上述那樣通過刀裝置52進行橡膠帶T的切斷。在該切斷時，如圖所示，在縫合的終端部上剩餘橡膠帶T的切斷端部Te，之後切斷端部Te被切除並被廢棄。該切斷端部Te在上述那樣的伸長狀態下被切斷，因此在切斷後收縮，其長度Ls比第11圖的情況的長度L大幅度縮短。因此，被切除及廢棄的橡膠帶T的量變少，在進行大量縫合處理的縫合工廠能夠有效地節省資源並削減成本。When the sewn portion of the rubber tape T is one turn, the rubber tape T is cut by the knife 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 off and discarded. Since the cut end portion Te is cut in the above-described extended state, the cut end portion Te is shrunk after cutting, and the length Ls is significantly shortened from the length L in the case of FIG. Therefore, the amount of the rubber tape T to be cut and discarded is reduced, and the sewing factory which performs a large number of stitching processes can effectively save resources and reduce costs.
第7圖是縫紉機30的控制框圖。縫紉機30通過控制部(控制電路)63控制縫紉機旋轉電動機64、帶狀物供給機構32的步進電動機55、切斷橡膠帶T的刀裝置52的活動刀驅動缸(未圖示)、及切斷坯料的緣部而對齊的刀裝置40。該控制部63回應所輸入的信號S1～S4而進行這些控制。信號S1～S3從由操作員的腳下來操作的踏板65輸出，信號S1是前踏入信號，信號S2是中立信號，信號S3是後踏入信號。並且，信號S4是從帶感測器56輸出的坯料有無信號。Fig. 7 is a control block diagram of the sewing machine 30. The sewing machine 30 controls the sewing machine rotation motor 64, the stepping motor 55 of the tape supply mechanism 32, the movable blade driving cylinder (not shown) of the blade device 52 that cuts the rubber tape T, and the cutting by the control unit (control circuit) 63. The knife device 40 is aligned with the edge of the blank. The control unit 63 performs these controls in response to the input signals S1 to S4. The signals S1 to S3 are outputted from the pedal 65 operated by the operator's foot. The signal S1 is the front stepping signal, the signal S2 is the neutral signal, and the signal S3 is the rear stepping signal. Further, the signal S4 is a blank presence/absence signal output from the belt sensor 56.
接著，參照第8圖的流程圖和第9圖的時序圖對縫紉機30的控制動作進行說明。第9圖中的時刻t0表示上次的縫合作業完成、並著手下一個縫合作業時的狀態。在時刻t1、踏板65被後踏入(步驟ST1)，控制部63回應踏板65的後踏入信號S3而使壓鐵37成爲上升位置，並在該狀態下取出縫合完成的三角褲70，並且能夠將下一個縫合的坯料70設置在針板36上。此時，步進電動機55正轉，只供給預定量的橡膠帶T，橡膠帶T被***到帶狀物引導口41(步驟ST2)。當坯料70的設置、橡膠帶T的***及向預定位置的安裝完成時，在時刻t2終止踏板65的後踏入而返回到中立位置。控制部63回應來自踏板65的中立信號S2，將壓鐵37下降到下降位置，由此在針板36上，在橡膠帶T重疊在坯料70上的狀態下壓鐵37從上面按壓。Next, the control operation of the sewing machine 30 will be described with reference to the flowchart of Fig. 8 and the timing chart of Fig. 9. The time t0 in Fig. 9 indicates the state when the previous sewing operation is completed and the next sewing operation is started. At time t1, the pedal 65 is stepped on (step ST1), and the control unit 63 returns the weight 37 to the raised position in response to the rear depression signal S3 of the pedal 65, and takes out the stitched pants 70 in this state, and The next stitched blank 70 can be placed on the needle plate 36. At this time, the stepping motor 55 rotates forward, and only a predetermined amount of the rubber tape T is supplied, and the rubber tape T is inserted into the tape guiding port 41 (step ST2). When the setting of the blank 70, the insertion of the rubber tape T, and the mounting to the predetermined position are completed, the stepping of the pedal 65 is terminated at time t2 to return to the neutral position. The control unit 63 responds to the neutral signal S2 from the pedal 65 to lower the weight 37 to the lowered position, whereby the weight 37 is pressed from the upper surface of the needle plate 36 with the rubber band T superposed on the blank 70.
接著，在時刻t3，操作員將踏板65前踏入到前踏入位置(步驟ST3)，並開始縫合作業。於是，前踏入信號S1被輸入控制部63，控制部63回應該信號而使縫紉機旋轉電動機64旋轉、驅動縫紉機，並且使帶狀物供給機構32的步進電動機55正轉(步驟ST4)。由此，橡膠帶T與坯料70一起被供給，在坯料70上縫合橡膠帶並被送出。並且，此時刀裝置(落刀裝置())40處於切斷位置，在坯料70送出的同時，腰圍部71的缘74被切斷而對齊。Next, at time t3, the operator steps the pedal 65 forward to the front stepping position (step ST3), and starts the sewing operation. Then, 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 rotates the stepping motor 55 of the ribbon supply mechanism 32 forward (step ST4). Thereby, the rubber tape T is supplied together with the blank 70, and the rubber tape is sewn on the blank 70 and sent out. And at this time, the knife device (falling device) )) 40 is in the cutting position, and the edge 74 of the waist portion 71 is cut and aligned while the blank 70 is being fed.
這樣，在坯料70的開口周緣部(腰圍部)71上縫裝橡膠帶T，當接近縫合完成時，在時刻t4如上述那樣使帶感測器56開啟而檢測存在帶端這一情況，該信號S4被輸入控制部63(步驟ST5)。此時，刀裝置(落刀裝置)40動作(步驟ST6)，停止刀裝置40對坯料70的切斷。之後，在時刻t5，當操作員停止踏板65的踏入時，縫紉機旋轉電動機64及步進電動機55的旋轉停止，橡膠帶T的縫合作業完成。In this way, 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 56 is opened at the time t4 to detect the presence of the tape end. The signal S4 is input to the control unit 63 (step ST5). At this time, the blade device (dropper device) 40 operates (step ST6), and the cutting of the blank 70 by the blade device 40 is stopped. Thereafter, at time t5, when the operator 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.
在時刻t6，當操作員進行踏板65的後踏入時(步驟ST7)，控制部63回應該後踏入信號S3而使步進電動機55反轉。由此，橡膠帶T被向供給方向的相反方向拉伸起來(步驟ST8)。同時，切線裝置(未圖示)動作，進行縫合線的切斷(步驟ST9)。接著，控制部63使刀裝置52動作，將由於拉起而伸長的橡膠帶T切斷，並且使壓鐵37成爲上升位置(步驟ST10)。At time t6, when the operator steps on the pedal 65 (step ST7), the control unit 63 returns to the signal S3 and reverses the stepping motor 55. Thereby, the rubber tape T is stretched in the opposite direction to the supply direction (step ST8). At the same time, the thread cutting device (not shown) operates to cut the suture (step ST9). Next, the control unit 63 operates the blade device 52 to cut the rubber band T that has been extended by the pulling up, and causes the weight 37 to be raised (step ST10).
通過橡膠帶T的切斷，完成三角褲70的橡膠帶縫合作業，在該狀態下壓鐵37處於上升位置，因此能夠取出如第6圖所示那樣的縫合完成的三角褲70。並且，在時刻t8，當操作員停止踏板65的後踏入而返回中立位置時(步驟ST11)，控制部63回應該中立信號S2而使刀裝置40成爲切斷位置(落刀裝置重定)(步驟ST12)，並且使壓鐵37成爲下降位置，而成爲下一個縫合動作的待機狀態。之後，設置新的坯料，重復步驟ST1～步驟ST12的動作，對三角褲70的腰圍部71進行橡膠帶T的縫合。對三角褲70的左右大腿部72、73的橡膠帶T的縫合也同樣地進行。這樣，完成了縫合的三角褲70，如第6圖所示那樣，橡膠帶T的切斷端部Te比現有的情況大幅度縮短，因此，即使在進行大量縫合處理的縫合工廠，被廢棄的橡膠帶T的量也被大幅度削減。並且，不需現有的縫紉機30本身的構造的變更，因此能夠僅通過動作程式的變更來實施，對用戶極其有益。By the cutting of the rubber tape T, the rubber band sewing operation of the briefs 70 is completed, and in this state, the weight 37 is in the raised position, so that the stitched pants 70 as shown in Fig. 6 can be taken out. At the time t8, when the operator stops the pedal 65 and then returns to the neutral position (step ST11), the control unit 63 returns the neutral signal S2 to turn the knife device 40 into the cutting position (the knife falling device is reset) ( In step ST12), the weight 37 is brought to the lowered position, and the standby state of the next sewing operation is performed. Thereafter, a new blank is set, and the operations of steps ST1 to ST12 are repeated, and the waist band 71 of the briefs 70 is sewn with the rubber tape T. The sewing of the rubber tape T of the left and right thigh portions 72, 73 of the briefs 70 is also performed in the same manner. As described above, the stitched end portion 70 of the rubber tape T is greatly shortened as compared with the conventional case as shown in Fig. 6, and therefore, it is discarded even in a sewing factory where a large number of stitching processes are performed. The amount of rubber band T has also been greatly reduced. Further, since the structure of the conventional sewing machine 30 itself is not required to be changed, it can be implemented only by changing the operation program, which is extremely beneficial to the user.
在上述動作流程中，以步驟ST5的帶端檢測(帶感測器開啟)之後的步驟ST7的踏板後踏入信號作爲觸發，而執行步驟ST8的帶拉起(帶輸送電動機反轉)及之後的步驟ST10的帶剪切，但本發明不限於此，例如也可以設置運針計數器，對從開始縫起的運針數進行計數，在計數出對應於橡膠縫裝完成的預定運針數時，向控制部63送出步進電動機55的反轉信號及刀裝置52的動作信號。或者，也可以將步驟ST5的帶端檢測(帶感測器開啟)信號S4作爲觸發，在該信號S4輸入後的預定時間經過後，送出步進電動機55的反轉信號及刀裝置52的動作信號。此時的預定時間爲，預先計算出第3圖所示的帶始端部Ts到達坯料感測器信號S4的輸入後縫合位置爲止的時間而設定。In the above-described operation flow, the pedal rear-stepping signal of step ST7 after the tape end detection (with sensor opening) of step ST5 is used as a trigger, and the belt pull-up (with conveyor motor reversal) of step ST8 is performed and thereafter. In the step ST10, the tape is cut, but the present invention is not limited thereto. For example, a needle counter may be provided to count the number of needles that are sewn from the start, and when the number of predetermined needles corresponding to the completion of the rubber sewing is counted, the control is performed. The portion 63 sends the reverse signal of the stepping motor 55 and the operation signal of the blade device 52. Alternatively, the tape end detection (with sensor on) signal S4 of step ST5 may be used as a trigger, and after the predetermined time after the input of the signal S4, the inversion signal of the stepping motor 55 and the operation of the knife device 52 are sent. signal. The predetermined time at this time is set in advance by calculating the time until the start end portion Ts shown in FIG. 3 reaches the input stitching position of the blank sensor signal S4.
另外，在上述實施方式中，對將本發明的帶狀物的縫合方法適用於扁平縫縫紉機的例子進行了說明，但適用物件也可以爲包縫機。Further, in the above-described embodiment, an example in which the sewing method of the belt of the present invention is applied to a flat seam sewing machine has been described. However, the applicable article may be an overlock sewing machine.
並且，作爲縫合完成後，對帶狀物賦予與供給方向相反方向的拉伸力的方法，對使供給輥對反轉的例子進行了描述，但也可以構成爲，在供給輥對和縫合位置之間配置對橡膠帶賦予張力的裝置(例如通過缸等進行動作的按壓部)，並在縫合完成後使該裝置動作。Further, as a method of imparting a tensile force in a direction opposite to the supply direction to the belt after completion of the stitching, an example in which the pair of supply rollers are reversed is described, but the pair of supply rollers and the stitching position may be configured. A device that applies tension to the rubber band (for example, a pressing portion that operates by a cylinder or the like) is disposed between the two, and the device is operated after the sewing is completed.
並且，帶感測器56是檢測在坯料的開口周緣部上縫合的帶是否通過的感測器，但也可以是對橡膠帶對坯料的重疊狀態進行光檢測的方法。此時，在橡膠縫裝途中，是在坯料上僅重疊1層橡膠帶的狀態，在腰圍部圍繞一周時，橡膠帶變成重疊2層的狀態。因此，能夠根據橡膠帶1層時的受光量和重疊2層時的受光量的差，判斷橡膠帶縫合是否完成。通過這種坯料感測器，即使操作員不操作，也能夠自動地判斷橡膠縫裝完成，並進行橡膠帶的拉起及切斷。作爲帶感測器56不限於例示的光斷路器方式的感測器，也可以是其他方式的感測器。Further, 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 light in a state in which the rubber tape overlaps the blank. At this time, 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 tape is in a state of overlapping two layers. Therefore, whether or not the rubber tape stitching is completed can be determined based on the difference between the amount of light received when the rubber tape is one layer and the amount of light received when the two layers are overlapped. With this blank sensor, even if the operator does not operate, it is possible to automatically judge that the rubber sewing is completed, and to pull up and cut the rubber band. The sensor with the sensor 56 is not limited to the illustrated photo interrupter type, and may be another type of sensor.
並且，帶狀物不限於橡膠帶，也可以是苦於伸縮性的布帶等。Further, the belt is not limited to a rubber belt, and may be a tape which is hard to stretch and the like.
