Abstract

The present invention provides a fabric sewing method and double-thread chain stitch sewing machine, the cloth is fed in the moving direction of sewing along the upper surface of the throat plate, and, at the same time, the two needles retaining the suture and moving vertically form the suture loop under the throat plate. Also, by moving forward the looper which can perform the backward and forward movement in the direction approximately orthogonal to the up-and-down moving path of the needle, the suture loop is catched. The catched suture loop is wound by the looper thread retained by the looper, thus a pin foot of double-thread chain stitches is formed on the cloth. At this moment, the convex suture end portion on the cloth surface when the first needle is sewed at the beginning of sewing is moved and guided in the pressed state by pressing and moving the guiding member toward the downstream side in the moving direction of sewing, thereby sewing the suture end portion into the pin foot of double-thread chain stitches. Therefore, the present sewing method saves the effort to cut the suture end portion protruded from the cloth surface when the first needle is sewed at the beginning of sewing. At the same time, the efficiency of sewing operation and the operational property of cloth are increased, and the damage of cloth is prevented.

Description

布料之縫製方法及雙重環縫縫紉機 Cloth sewing method and double loop sewing machine
本發明係關於一種例如使用以橫筒形為代表之雙重環縫縫紉機,如T恤衫或內衣等般將前後片布料先縫合而用以防止被加工成環(loop)狀之完整布料之端部脫線的下擺翻邊縫等布料之縫製方法、以及該縫製中使用之雙重環縫縫紉機。 The present invention relates to, for example, a double loop sewing machine represented by a horizontal cylinder, such as a T-shirt or an underwear, which is used to suture the front and back sheets to prevent the end of the complete fabric which is processed into a loop shape. A method of sewing a fabric such as a hem of a hem, and a double loop sewing machine used in the sewing.
例如,以雙重環縫縫紉機之完整布料之下擺翻邊縫為例進行說明,一面將完整布料之縫製部分(將端緣部向布料之背面側翻摺疊合而成之布料部分)沿著針板之上表面而於規定的縫製行進方向上進給,一面藉由保持針線且上下移動之至少1根針而於針板下形成針線圏,並且藉由在與針之上下移動路徑大致正交之方向上執行進退動作的線鉤之前進而捕捉針線圏,將該捕捉到的針線圏藉由線鉤所保持之線鉤線而與其他線進行打環(looping),藉此,於布料之縫製部分形成雙重環縫之針腳。 For example, the double-stitch sewing machine is described as an example of a slanting edge under the complete fabric, and the sewing portion of the complete fabric (the portion of the fabric that folds the end edge toward the back side of the fabric) along the needle plate The upper surface is fed in a predetermined sewing traveling direction, and the needle thread is formed under the needle plate by at least one needle that holds the needle thread and moves up and down, and is substantially orthogonal to the movement path above and below the needle. The thread hook is further captured in the direction of the forward and backward movement, and the captured needle thread is looped with the other thread by the thread hook held by the hook, thereby sewing the cloth. Form a double loop stitch.
於形成如上所述之雙重環縫之針腳的布料之縫製中,如圖10所示,於針1自布料W之上方貫通布料W而向布料W之下方移動的縫製起始第1針之縫製時,針線NT之前端部分於布料W之表面Wf上凸出。其結果如圖11所示,產生品質不良,即,於下擺翻邊縫完成後之T恤衫等之下擺周長之一部分有針線端部分NTa凸出而殘留,從而使縫製製品之價值降低。 In the sewing of the fabric forming the stitches of the double loop stitch as described above, as shown in FIG. 10, the first stitch of the sewing start is performed by the needle 1 passing through the fabric W from above the fabric W and moving below the fabric W. At the time, the front end portion of the needle thread NT protrudes on the surface Wf of the cloth W. As a result, as shown in Fig. 11, the quality is poor, that is, the stitch end portion NTa is protruded and remains in one of the hem circumferences of the T-shirt or the like after the hem of the hem is completed, so that the value of the sewn product is lowered.

根據具有如上所述之特徵構成的本第1至第4發明之布料之縫製方法及雙重環縫縫紉機,將縫製起始第1針之縫製時於布料之表面上凸出之針線端部分,於第2針以後之縫製動作時朝縫製行進方向之下游側以壓倒狀態移動導引,對該被壓倒移動導引之針線端部分進行縫入雙重環縫之針腳中的處理,藉此,操作人員無需花費工夫手持剪刀將藉由縫製起始第1針之縫製而於布料之表面上凸出的針線端部分進行手動切斷,從而可達成省力化,不僅如此,亦可消除用於手動切斷之時間損耗從而謀求縫製作業之效率提高。而且,由於操作人員無需手持剪刀,故而手之自由度增加,從而布料之操作性變佳,且亦可謀求縫製品質之提高。又,藉由剪刀而損壞布料之情形亦幾乎消除,從而發揮可抑制縫製製品之價值降低之效果。 According to the sewing method and the double loop sewing machine of the first to fourth inventions having the above-described features, the needle end portion which protrudes on the surface of the cloth at the time of sewing the first stitch is formed. In the sewing operation after the second stitching, the downstream side of the sewing traveling direction is guided by the push-down state, and the needle end portion of the overturned moving guide is sewn into the stitch of the double loop stitch, whereby the operator It is not necessary to take the time to manually cut the needle thread end portion which is projected on the surface of the cloth by sewing the sewing of the first stitch, so that labor saving can be achieved, and the manual cutting can be eliminated. The loss of time leads to an increase in the efficiency of the sewing operation. Moreover, since the operator does not need to hold the scissors, the degree of freedom of the hand is increased, so that the operability of the cloth is improved, and the quality of the sewing product can be improved. Moreover, the situation in which the fabric is damaged by the scissors is almost eliminated, and the effect of suppressing the reduction in the value of the sewn product is exhibited.
尤其如本第2發明及第4發明般,於以完整布料為縫製對象進行下擺翻邊縫之情形時,係對縫製起始部分與縫製結束部分進行稍許重疊縫製,此時,由於可將藉由縫製起始第1針之縫製而於布料之表面上凸出之針線端部分伴隨第2針以後之縫製動作而朝縫製行進方向之下游側壓倒移動導引,且進行縫入雙重環縫之針腳中的處理,因此,與在縫製中途暫且中斷縫製動作而手持剪刀對針線端部分進行切斷處理之後再開始縫製動作進行重疊縫製之情形相比,可包含縫製結束部分之重疊縫製在內而一下子連續地對完整布料之整周進行下擺翻邊縫,從而發揮可消除用於線處理之時間損耗從而謀求縫製作業效率之進一步提高的效果。 In particular, in the case of the hem of the hem, the sling start portion and the end portion of the sew are slightly overlapped when the sling is sewed with the complete fabric as the object of the second invention and the fourth invention. The needle thread end portion which is sewn on the surface of the cloth by the sewing of the stitching start stitching is guided by the sewing operation after the second stitching, and is guided by the downstream side in the sewing traveling direction, and is sewn into the double loop stitch. Since the processing in the stitches is performed, and the sewing operation is temporarily interrupted in the middle of sewing, the hand-held scissors cuts the needle thread end portion and then the sewing operation is started, and the sewing operation may be performed, and the overlapping sewing portion may be included. The hem hem seam is continuously applied to the entire circumference of the entire fabric at one time, thereby exhibiting an effect of eliminating the time loss for the wire processing and further improving the sewing work efficiency.
於本第1發明及第2發明之布料之縫製方法中,較佳為對於縫製起始第1針時於布料之表面上凸出之上述針線端部分,進行與形成該針腳之複數個針線圏平行或大致平行地縫入雙重環縫之針腳的處理。 In the sewing method of the cloth according to the first aspect of the invention and the second aspect of the invention, it is preferable that the needle thread end portion which is projected on the surface of the cloth when the first stitch is started to be stitched is formed with a plurality of stitches forming the stitch. The process of sewing the stitches of the double loop stitch in parallel or substantially parallel.
該情形時,對於縫入至布料之背面側之針線部分,進行與形成針腳之複數個針線圏平行或大致平行地縫入雙重環縫之針腳中的處理,故而即便自布料之背面側觀察時,針腳紋路之淩亂亦非常少,從而可獲得外觀較佳之縫製品質狀況。 In this case, the stitching portion that is sewn to the back side of the cloth is sewn into the stitches of the double loop stitch in parallel or substantially parallel with the plurality of stitches forming the stitches, so that even when viewed from the back side of the cloth The stitching of the stitches is also very small, so that the quality of the seams with better appearance can be obtained.
又,於本第3發明及第4發明之雙重環縫縫紉機中,較佳為上述針線傾倒移動導引構件係在藉由設置於上述針板之下表面或上表面的縫製行進方向之前後兩端附近的導件而沿上述針板之下表面或上表面可於縫製行進方向上滑動移動地受到支持的帶板狀構件上,形成有一對上下方向貫通孔部、與針線壓倒部而構成;上述一對上下方向貫通孔部係於該帶板狀構件滑動移動至較上述針之上下移動路徑更靠近縫製行進方向之上游側時、以及滑動移動至較上述針之上下移動路徑更靠近縫製行進方向之下游側時,與上述針板之落針部及布料進給齒用出沒槽連通;上述針線壓倒部係位於該等一對貫通孔部之間,且於自上述縫製行進方向之上游側之位 置朝下游側之位置移動時與凸出於布料之表面上之針線端部分相抵接,而將該針線端部分朝縫製行進方向之下游側壓倒。 Further, in the double-stitch sewing machine according to the third aspect of the invention, it is preferable that the needle threading movement guiding member is disposed before the sewing traveling direction provided on the lower surface or the upper surface of the needle plate. a strip-shaped member that is slidably supported in the sewing traveling direction along the lower surface or the upper surface of the needle plate, and a pair of up-and-down direction through-hole portions and a needle thread over-pressure portion are formed; The pair of up-and-down direction through-hole portions are slidably moved closer to the upstream side in the sewing traveling direction than the needle upper-lower moving path, and are slidably moved closer to the sewing direction than the needle upper-lower moving path. When the downstream side of the direction is in contact with the needle drop portion of the needle plate and the cloth feeding tooth outlet groove, the needle thread crushing portion is located between the pair of through hole portions and is upstream from the sewing traveling direction Position When moving to the position on the downstream side, it abuts against the needle end portion on the surface of the cloth, and the needle end portion is pressed against the downstream side in the sewing traveling direction.
該情形時,可由沿縫製行進方向較長之帶板狀構件構成針線傾倒移動導引構件,且可藉由設置於針板之下表面或上表面之縫製行進方向之前後兩端附近的導件而使針線傾倒移動導引構件於縫製行進方向上很穩定且順利地滑動移動,並且於縫製起始第1針之縫製動作及第2針以後之縫製動作時切換為使一對貫通孔部中之任一方與落針部及布料進給齒用出沒槽連通的狀態,藉此,針線傾倒移動導引構件不會成為布料進給齒之出沒運動及針之上下運動的阻礙,故而可一方面保持始終正常地執行規定的縫製動作之狀態,一方面切實地將凸出於布料之表面上的針線端部分壓倒而進行將其縫入針腳中的處理。 In this case, the needle-like tilting movement guiding member may be constituted by the strip-shaped member which is long in the traveling direction of the sewing, and the guide member may be provided in the vicinity of the front and rear ends in the traveling direction by sewing on the lower surface or the upper surface of the needle plate. Further, the needle thread tilting movement guide member is stably and smoothly slidably moved in the sewing traveling direction, and is switched to the pair of through hole portions at the sewing start stitching operation and the sewing operation after the second stitching. In either of the state in which the needle drop portion and the cloth feed tooth are in communication with each other, the needle thread tilting movement guide member does not hinder the movement of the cloth feed tooth and the movement of the needle up and down. The state in which the predetermined sewing operation is always performed normally is performed, and on the other hand, the process of sewing the needle thread end portion protruding from the surface of the cloth to the stitch is performed.
又,於本第3發明及第4發明之雙重環縫縫紉機中,較佳為上述針線傾倒移動導引構件以如下方式構成:於上述線鉤線自線鉤線切斷用刀刃機構中之線鉤線保持部上脫落之時機,強制性地使上述針線傾倒移動導引構件自上述縫製行進方向之上游側之位置朝下游側之位置移動。 Further, in the double-stitch sewing machine according to the third aspect of the invention, it is preferable that the needle threading movement guide member is configured to be in the line of the thread hook line cutting blade mechanism. At the timing when the hook wire holding portion is detached, the needle thread tilting movement guide member is forcibly moved from the position on the upstream side in the sewing traveling direction toward the downstream side.
該情形時,於布料之表面上凸出之針線端部分在於第2針以後之縫製動作時朝縫製行進方向之下游側時以壓倒狀態移動導引時,藉由該被壓倒移動導引之針線端部分而容易使線鉤線之端部分亦一同縫入針腳中,抑制線鉤線端部分自針腳朝側方較大地露出,從而可獲得外觀更佳之縫製品質狀況。 In this case, the needle end portion that protrudes on the surface of the cloth is guided by the overturned movement when the needle is moved in the overwhelming state toward the downstream side in the sewing traveling direction during the sewing operation after the second stitch. The end portion is easy to sew the end portions of the wire hooks into the stitches together, and the end portions of the wire hooks are prevented from being largely exposed from the stitches toward the side, so that a better appearance of the seam product can be obtained.
又,於本第3發明及第4發明之雙重環縫縫紉機中,作為對象之縫紉機,適宜為雙針型式之橫筒形雙重環縫縫紉機,但亦可將單針型式之橫筒形雙重環縫縫紉機、橫筒形以外之單針或雙針雙重環縫縫紉機、或平台型之雙重環縫縫紉機作為對象縫紉機。 Further, in the double loop sewing machine according to the third invention and the fourth aspect of the invention, the sewing machine to be used is preferably a double needle type horizontal cylindrical double loop sewing machine, but a single needle type horizontal cylindrical double ring may be used. Sewing machine, single or double needle double loop sewing machine other than horizontal cylinder, or platform type double loop sewing machine as the target sewing machine.
進而,於雙針型式之橫筒形雙重環縫縫紉機中,較佳為上述 針線傾倒移動導引構件中之針線壓倒部之對於針線端部分的抵接緣部形成為大致圓弧狀,該大致圓弧狀係隨著自寬度方向之兩側部朝中央部之行進,而逐漸位於縫製行進方向之上游側。 Further, in the double needle type horizontal cylindrical double loop sewing machine, preferably the above The abutting edge portion of the needle thread overturning portion in the needle threading movement guiding member is formed in a substantially arc shape, and the substantially arc shape follows the center portion from the both sides in the width direction. Gradually located on the upstream side of the sewing travel direction.
該情形時,針線傾倒移動導引構件朝縫製行進方向Y之下游側滑動移動且藉由針線壓倒部而將2根針線端部分壓倒時,該等2根針線端部分沿著大致圓弧狀之抵接緣部而朝相互接近之方向移位,故而可將被壓倒之2根針線端部分於雙重環縫之針腳之寬度內切實且美觀地進行縫入處理。 In this case, when the needle thread tilting movement guide member slides toward the downstream side of the sewing traveling direction Y and the two needle thread end portions are overwhelmed by the needle thread overturning portion, the two needle thread end portions are substantially arc-shaped. Since the edge portions are abutted and displaced in the direction in which they approach each other, the two needle thread end portions that are overwhelmed can be sewn and processed beautifully and beautifully within the width of the stitches of the double loop stitches.

如圖1所示,本實施形態之橫筒形雙重環縫縫紉機M係用於T恤衫之下擺翻邊縫等完整布料W之縫製者,縫紉機臂部C及縫紉機台板部B自縫紉機主體部D之上下位置朝左方以相互大致平行狀而延設。如圖2所示,該橫筒形雙重環縫縫紉機M具備:2根針1,其保持針線NT而於上下方向上往復運動;線鉤2,其保持線鉤線LT而在相對於上述針1之上下運動路徑正交之方向上執行進退動作;針板3;固定金屬件4(參照圖1);布料前進給齒及後進給齒(因眾所周知,故省略圖示);線鉤線切斷用刀刃機構9,其於縫製結束時切斷線鉤線LT且夾著該切斷之線鉤線端部分LTa進行保持;及下述之針線傾倒移動導引構件5。 As shown in Fig. 1, the horizontal cylindrical double-loop sewing machine M of the present embodiment is used for sewing a complete fabric W such as a t-shirt under the T-shirt, and the sewing machine arm portion C and the sewing machine table portion B are from the main body of the sewing machine. The upper and lower positions of D are extended to the left in a substantially parallel shape. As shown in Fig. 2, the horizontal cylindrical double-stitch sewing machine M includes two needles 1 that reciprocate in the up-and-down direction while holding the needle thread NT, and a thread hook 2 that holds the thread hook line LT in relation to the needle 1 advance and retreat operation in the direction in which the upper and lower movement paths are orthogonal; the needle plate 3; the fixed metal member 4 (refer to FIG. 1); the cloth advancement to the teeth and the rear feed tooth (so that the illustration is omitted); the line hook line is cut The cutting blade mechanism 9 is used to cut the wire hook line LT at the end of sewing and hold the wire hook end portion LTa between the cutting wires; and the needle thread below to move the guiding member 5.
針1係經由針安裝具13安裝於與縫紉機臂部C內之縫紉機主軸(省略圖示)之旋轉連動地上下移動的針棒12之下端部,從而上升及 下降。 The needle 1 is attached to the lower end portion of the needle bar 12 that moves up and down in conjunction with the rotation of the sewing machine main shaft (not shown) in the sewing machine arm portion C via the needle attachment tool 13 to rise and decline.
線鉤2係經由線鉤驅動機構之動作而在與針1之上下運動路徑大致正交之方向上執行進退(左進及右退)動作。 The hook 2 performs the advance and retreat (leftward and rightward) operations in a direction substantially orthogonal to the upper and lower movement paths of the needle 1 via the action of the hook drive mechanism.
針板3係安裝於縫紉機台板部B之上表面,如圖1所示,載置有於完整布料W之下擺部將布料端緣部向布料背面側翻摺疊合而成之疊合布料部分,且導引該完整布料W之疊合布料部分朝規定的縫製方向Y之進給。 The needle plate 3 is attached to the upper surface of the sewing machine table portion B, and as shown in Fig. 1, the overlapping cloth portion is formed by folding the cloth edge portion toward the back side of the cloth under the entire cloth W. And guiding the superimposed cloth portion of the complete fabric W to feed in a predetermined sewing direction Y.
於針板3上,如圖2及圖3所示,形成有供上述2根針1貫通之落針部3a、及布料前進給齒及布料後進給齒用之出沒槽3b、3c,該等出沒槽3b、3c反覆執行以下動作而斷續地、強制性地將完整布料W於縫製行進方向Y上進給,該動作係指突出於針板3上而在縫製行進方向Y上移動、且沒入至針板3下而在與縫製行進方向Y相反之方向上進行復原移動。 As shown in FIG. 2 and FIG. 3, the needle plate 3 is formed with a needle drop portion 3a through which the two needles 1 pass, and a cloth feed forward tooth and a feed groove for the cloth feed teeth 3b, 3c. The culling grooves 3b and 3c repeatedly perform the following operations to intermittently and forcibly feed the entire fabric W in the sewing traveling direction Y, which is projected on the needle plate 3 to move in the sewing traveling direction Y, and The detachment into the needle plate 3 is performed in a direction opposite to the sewing traveling direction Y.
橫筒形雙重環縫縫紉機係藉由針1之上升及下降動作、與線鉤2之前進及後退動作,而對載置於針板3上之完整布料W之疊合布料部分進行縫製。完整布料W係藉由固定金屬件4而壓在針板3上,且藉由設置於縫紉機台板B之內部的布料前進給齒及後進給齒之動作,而於圖2之箭頭Y所示之縫製行進方向上進行進給移動。 The horizontal cylindrical double loop sewing machine sewn the laminated fabric portion of the complete fabric W placed on the needle board 3 by the raising and lowering action of the needle 1 and the forward and backward movement of the thread hook 2. The complete fabric W is pressed against the needle plate 3 by the fixing metal member 4, and the movement of the cloth disposed inside the sewing machine table B is advanced to the teeth and the rear feeding teeth, as indicated by an arrow Y in FIG. The feed movement is performed in the sewing travel direction.
上述之針棒12、線鉤驅動機構及布料進給齒之驅動機構係藉由來自縫紉機主軸(省略圖示)之傳動而彼此同步動作的公知機構。針1保持針線NT,且於完整布料W之進給停止之期間,貫通於該完整布料W之疊合布料部分而到達針板3之下,其後,上升而朝完整布料W之上方脫出。線鉤2保持線鉤線LT,且配合針1之開始上升而前進,捕捉形成於針板3下之針線NT的環NTb。完整布料W係於針1上升時進行進給移動。針1穿過經進給移動之完整布料W後下降,捕捉後退中之線鉤2所保持之線鉤線LT,且藉由該捕捉到的線鉤線LT而將上述針線圏NTb打環。雙重 環縫縫紉機M反覆執行以上動作,於完整布料W之下擺部形成雙重環縫之針腳。 The above-described needle bar 12, the wire hook drive mechanism, and the drive mechanism for the cloth feed teeth are known mechanisms that operate in synchronization with each other by a drive from a sewing machine spindle (not shown). The needle 1 holds the needle thread NT, and passes through the overlapping fabric portion of the complete fabric W to reach below the needle plate 3 during the stop of the feed of the complete fabric W, and then rises to come out over the complete fabric W. . The wire hook 2 holds the wire hook line LT, and advances with the start of the engagement needle 1, and catches the ring NTb of the needle thread NT formed under the needle plate 3. The complete cloth W is fed when the needle 1 is raised. The needle 1 passes through the complete cloth W that has been fed by the feed, and then descends, catches the line hook line LT held by the thread hook 2 in the backward movement, and loops the needle thread 圏NTb by the captured line hook line LT. double The loop sewing machine M repeatedly performs the above actions to form a double loop stitch on the pendulum under the complete cloth W.
於如上所述橫筒形雙重環縫縫紉機M中,在上述針板3之下表面上,具備針線傾倒移動導引構件5、及作為致動器之氣缸6,該氣缸6強制性地使該針線傾倒移動導引構件5移動至較針1之上下運動路徑更靠近縫製行進方向Y之上游端側之位置與下游端側之位置。 In the horizontal cylindrical double-stitch sewing machine M as described above, the lower surface of the needle plate 3 is provided with a needle thread tilting movement guiding member 5 and a cylinder 6 as an actuator, which is forcibly The needle thread dumping movement guide member 5 is moved to a position closer to the upstream end side of the sewing traveling direction Y than the upper end side of the needle 1 and the downstream end side.
如圖3所示,上述針線傾倒移動導引構件5係由帶板狀構件8構成,該帶板狀構件8係藉由在針板3之下表面固定於縫製行進方向Y之前後兩端附近的滑動導件7、7,而可在針板3之下表面上於縫製行進方向Y上往復滑動地受到支持。於該帶板狀構件8上,在滑動方向上並排形成有一對貫通孔部8a、8b,該一對貫通孔部8a、8b係於該帶板狀構件8滑動移動至縫製行進方向Y之上游側時、以及滑動移動至縫製行進方向Y之下游側時,分別與上述針板3之落針部3a及布料進給齒用出沒槽3b連通,並且,於該等一對貫通孔部8a、8b之間形成有針線壓倒部8c。又,於上述帶板狀構件8之縫製行進方向Y之上游端形成有止動部8d,於該帶板狀構件8滑動移動至縫製行進方向Y之下游側時,該止動部8d與上述滑動導件7、7中之一方相抵接,而使其停止進一步朝下游側之滑動移動。 As shown in Fig. 3, the needle threading tilting guide member 5 is constituted by a strip-shaped member 8 which is fixed by the lower surface of the needle plate 3 before and after the sewing traveling direction Y. The sliding guides 7, 7 are supported on the lower surface of the needle plate 3 in a reciprocating sliding direction in the sewing traveling direction Y. In the strip-shaped member 8, a pair of through-hole portions 8a, 8b are formed in parallel in the sliding direction, and the pair of through-hole portions 8a, 8b are slidably moved to the upstream of the sewing traveling direction Y by the strip-shaped member 8 When the side and the sliding movement are moved to the downstream side of the sewing traveling direction Y, respectively, the needle dropping portion 3a of the needle plate 3 and the cloth feeding tooth outlet groove 3b are communicated with each other, and the pair of through hole portions 8a, A needle thread overturning portion 8c is formed between 8b. Further, a stopper portion 8d is formed at an upstream end of the belt-shaped member 8 in the sewing traveling direction Y, and when the belt-like member 8 is slidably moved to the downstream side in the sewing traveling direction Y, the stopper portion 8d and the above One of the sliding guides 7, 7 abuts, causing it to stop further sliding movement toward the downstream side.
構成上述針線傾倒移動導引構件5之帶板狀構件8係以如下方式構成:於縫製起始第1針之縫製時,經由氣缸6而滑動移動至縫製行進方向Y之上游側,且於該位置上,針線壓倒部8c與縫製起始第1針之縫製時凸出於完整布料W之表面上的針線端部分NTa相抵接。然後,於第2針之縫製動作前帶板狀構件8經由氣缸6而朝縫製行進方向Y之下游側滑動移動時,藉由針線壓倒部8c而將於完整布料W之表面上凸出之針線端部分NTa朝縫製行進方向Y之下游側以壓倒狀態移動導引。 The strip-shaped member 8 constituting the needle thread tilting movement guide member 5 is configured to be slidably moved to the upstream side of the sewing traveling direction Y via the air cylinder 6 at the time of sewing the sewing first stitch, and In the position, the needle thread overcending portion 8c abuts against the needle thread end portion NTa on the surface of the complete cloth W at the time of sewing of the sewing start first needle. Then, when the strip-shaped member 8 is slidably moved toward the downstream side in the sewing traveling direction Y via the air cylinder 6 before the sewing operation of the second stitch, the needle thread protruding from the surface of the complete fabric W by the needle thread overturning portion 8c The end portion NTa is guided in a collapsed state toward the downstream side of the sewing traveling direction Y.
上述帶板狀構件8中之針線壓倒部8c之對於針線端部分 NTa的抵接緣部8e係形成為大致圓弧狀,該大致圓弧狀係隨著自寬度方向之兩側部朝中央部之行進,而逐漸位於縫製行進方向Y之上游側。藉此,帶板狀構件8滑動移動至縫製行進方向Y之下游側且藉由針線壓倒部8c而將2根針線端部分NTa壓倒時,2根針線端部分NTa沿著大致圓弧狀之抵接緣部8e而朝相互接近之方向移位。 The needle thread end portion 8c of the above-described strip-like member 8 is for the needle end portion The abutting edge portion 8e of the NTa is formed in a substantially arc shape, which is gradually located on the upstream side in the sewing traveling direction Y as the both sides in the width direction travel toward the center portion. Thereby, when the strip-shaped member 8 is slidably moved to the downstream side of the sewing traveling direction Y and the two needle thread end portions NTa are overwhelmed by the needle thread crimping portion 8c, the two needle thread end portions NTa are substantially arc-shaped. The edge portions 8e are displaced in the direction in which they approach each other.
其次,參照圖4至圖8對以下動作進行說明,該動作係指使用上述構成之橫筒形雙重環縫縫紉機M,對T恤衫之下擺部等完整布料W進行下擺翻邊縫的動作。 Next, the following operation will be described with reference to FIGS. 4 to 8 , which is an operation of swaying and sewing a complete fabric W such as a lower portion of a T-shirt under the use of the horizontal cylindrical double-loop sewing machine M having the above-described configuration.
於縫製起始第1針之縫製時,如圖3及圖4所示,構成上述針線傾倒移動導引構件5之帶板狀構件8經由氣缸6而滑動移動至縫製行進方向Y之上游側。 As shown in FIG. 3 and FIG. 4, the strip-shaped member 8 constituting the needle thread tilting movement guide member 5 is slidably moved to the upstream side in the sewing traveling direction Y via the air cylinder 6 as shown in FIGS. 3 and 4 .
該狀態下,針1貫通於完整布料W之疊合布料部分且經過針板3之落針部3a及帶板狀構件8之一貫通孔部8a而到達針板3之下,其後,上升而朝完整布料W之上方脫出,於該狀態下執行縫製起始第1針之縫製動作。藉此,於針板3之下形成針線圏NTb,且於完整布料W之表面Wf上針線端部分NTa凸出地殘留,其與構成上述針線傾倒移動導引構件5之帶板狀構件8中之針線壓倒部8c的抵接緣部8e相抵接。又,配合針1之開始上升,完整布料W藉由前後之進給齒而於縫製行進方向Y上進給,並且線鉤2前進,捕捉形成於針板3下之針線圏NTb。 In this state, the needle 1 passes through the overlapping fabric portion of the complete fabric W and passes through the needle drop portion 3a of the needle plate 3 and one of the strip-like members 8 through the hole portion 8a to reach the needle plate 3, and thereafter rises. In the state where the sewing is started, the stitching operation of the first stitch is performed. Thereby, the needle thread 圏NTb is formed under the needle plate 3, and the needle thread end portion NTa is convexly left on the surface Wf of the entire cloth W, which is in the strip-like member 8 constituting the needle thread tilting movement guiding member 5. The abutting edge portion 8e of the needle thread crushing portion 8c abuts. Further, with the start of the engagement of the needle 1, the entire fabric W is fed in the sewing traveling direction Y by the feed teeth of the front and rear, and the thread hook 2 advances to capture the needle thread 圏NTb formed under the needle plate 3.
然後,如圖5所示,於線鉤2前進至規定位置而使線鉤線LT之線端部分LTa自線鉤線切斷用刀刃機構9之線鉤線保持部上脫落之時機,使構成上述針線傾倒移動導引構件5之帶板狀構件8藉由氣缸6而自縫製行進方向Y之上游側朝下游側滑動移動。 Then, as shown in FIG. 5, when the wire hook 2 is advanced to a predetermined position and the wire end portion LTa of the wire hooking wire LT is detached from the wire hook wire holding portion of the wire hook cutting blade mechanism 9, the frame is formed. The strip-shaped member 8 of the needle thread dumping movement guide member 5 is slidably moved from the upstream side of the sewing traveling direction Y toward the downstream side by the air cylinder 6.
如圖6所示,藉由上述帶板狀構件8朝縫製行進方向Y之下游側之滑動移動,而使於縫製起始第1針之縫製動作時保持凸出於完整 布料W之表面Wf上之狀態而與帶板狀構件8之針線壓倒部8c的抵接緣部8e相抵接的針線端部分NTa,藉由該抵接緣部8e而朝縫製行進方向Y之下游側以壓倒狀態移動導引。 As shown in Fig. 6, by the sliding movement of the strip-shaped member 8 toward the downstream side in the sewing traveling direction Y, the sewing operation of the first stitch during the sewing start is kept intact. The needle end portion NTa that abuts against the abutting edge portion 8e of the needle thread crushing portion 8c of the plate-like member 8 on the surface Wf of the cloth W is downstream of the sewing traveling direction Y by the abutting edge portion 8e. The side moves in a collapsed state.
於向該壓倒狀態之移動導引時,由於抵接緣部8e為大致圓弧狀,故2根針線端部分NTa沿著該大致圓弧狀之抵接緣部8e朝相互接近之方向移位。又,於帶板狀構件8滑動移動至縫製行進方向Y之下游側的狀態下,該帶板狀構件8之另一貫通孔部8b亦與針板3之落針部3a及布料進給齒用出沒槽3連通,不會成為其後之布料進給齒之出沒運動及針之上下運動的阻礙,因此可保持正常地執行第2針以後之縫製動作之狀態。 When the abutting edge portion 8e is substantially arc-shaped, the two needle end portions NTa are displaced toward each other along the substantially arc-shaped abutting edge portion 8e. . Further, in a state in which the strip-shaped member 8 is slidably moved to the downstream side in the sewing traveling direction Y, the other through-hole portion 8b of the strip-shaped member 8 is also attached to the needle-drop portion 3a of the needle plate 3 and the cloth feeding tooth. When the hair supply groove 3 is connected, it does not become an obstacle to the movement of the subsequent feeding teeth of the cloth and the movement of the needle up and down. Therefore, the sewing operation after the second stitch can be normally performed.
接下來,如圖7及圖8所示,藉由針1之上升下降運動、線鉤2之進退運動、及布料前後進給齒對完整布料之進給作用,而執行第2針以後之縫製動作。伴隨該第2針以後之縫製動作,線鉤2捕捉到的針線圏NTb藉由線鉤線LT而依序打環而進行雙重環縫。 Next, as shown in FIG. 7 and FIG. 8 , the sewing operation of the second stitch is performed by the ascending and descending movement of the needle 1 , the advance and retreat movement of the thread hook 2 , and the feeding of the front and rear feed teeth to the complete fabric. action. With the sewing operation after the second stitch, the needle thread 圏NTb caught by the hook 2 is sequentially looped by the hook line LT to perform double loop stitching.
然後,如圖9所示,於第1針之縫製動作剛結束後藉由上述針線傾倒移動導引構件5而朝縫製行進方向Y之下游側以壓倒狀態移動導引的2根針線端部分NTa係受到縫入雙重環縫之針腳A中的處理。此時,對於2根針線端部分NTa以相互接近之狀態與雙重環縫之針腳A平行或大致平行地進行縫入處理。又,線鉤線端部分LTa亦與被壓倒移動導引之針線端部分NTa一同受到縫入針腳A中的處理。 Then, as shown in FIG. 9, after the sewing operation of the first stitch is completed, the two needle thread end portions NTa that are guided in the overwhelming state are moved toward the downstream side of the sewing traveling direction Y by the needle threading movement guide member 5. It is subjected to the treatment in the stitch A of the double loop stitch. At this time, the sewing process is performed in parallel or substantially parallel with the stitch A of the double loop stitch in a state in which the two needle thread end portions NTa are close to each other. Further, the wire hook end portion LTa is also subjected to the process of sewing into the stitch A together with the needle end portion NTa of the overturning movement guide.
藉由如上之動作,進行於完整布料W之疊合布料部分之整周上形成雙重環縫之針腳A的下擺翻邊縫,於該下擺翻邊縫時,對於縫製起始第1針之縫製時於布料W之表面Wf上凸出的針線端部分NTa,於第2針之縫製前進行縫入雙重環縫之針腳A中的處理,藉此,操作人員完全無需花費工夫手持剪刀進行手動切斷從而可達成省力化,不僅如此,亦可消除用於手動切斷之時間損耗而謀求縫製作業之效率提高。又,由於操作人 員無需手持剪刀,故而手之自由度增加,從而布料W之操作性變佳,且亦可謀求縫製品質之提高。進而,亦幾乎不存在因剪刀而損壞布料W之情形,從而可抑制縫製製品之價值之降低。 By the above action, the hem flange of the double loop stitch A is formed on the entire circumference of the folded fabric portion of the complete fabric W, and the stitching of the first stitch is started at the hem of the hem. The needle end portion NTa protruding on the surface Wf of the cloth W is subjected to the process of sewing the stitch A of the double loop stitch before the sewing of the second stitch, whereby the operator does not need to take the time to manually cut the scissors. In addition, the labor can be reduced, and the time loss for manual cutting can be eliminated, and the efficiency of the sewing operation can be improved. Again, due to the operator The person does not need to hold the scissors, so the degree of freedom of the hand is increased, so that the operability of the cloth W is improved, and the quality of the seam product can be improved. Further, there is almost no case where the cloth W is damaged by the scissors, and the reduction in the value of the sewn product can be suppressed.
尤其如本實施形態般,於以完整布料W為縫製對象進行下擺翻邊縫之情形時,係對縫製起始部分與縫製結束部分進行稍許重疊縫製,此時,由於可將藉由縫製起始第1針之縫製而於布料W之表面上凸出的針線端部分NTa伴隨第2針以後之縫製動作而朝縫製行進方向Y之下游側壓倒移動導引,而進行縫入雙重環縫之針腳A中的處理,因此,無需於縫製中途暫且中斷縫製動作且手持剪刀對針線端部分NTa以手動方式進行切斷處理之後再開始縫製動作而進行重疊縫製,可包含縫製結束部分之重疊縫製在內而一下子連續地對完整布料W之整周進行下擺翻邊縫。藉此,可消除用於針線端部分NTa之處理之時間損耗從而謀求縫製作業效率之進一步提高。 In particular, as in the case of the present embodiment, when the hem of the hem is performed with the complete fabric W as the object to be sewn, the sewing start portion and the end portion of the sewing are slightly overlapped, and at this time, since sewing can be started The needle thread end portion NTa which is sewn on the surface of the cloth W by the first stitch is pushed and guided by the downstream side of the sewing traveling direction Y with the sewing operation after the second stitch, and the stitch stitched into the double loop stitch is performed. In the process of A, it is not necessary to temporarily interrupt the sewing operation in the middle of sewing, and the hand-held scissors manually cuts the needle thread end portion NTa and then starts the sewing operation to perform the overlapping sewing, which may include the overlapping sewing of the sewing end portion. At the same time, the hem of the entire fabric W is continuously creased. Thereby, the time loss for the processing of the needle thread end portion NTa can be eliminated, and the sewing work efficiency can be further improved.
又,由於對針線端部分NTa進行與各針線圏NTb平行或大致平行地縫入針腳A中的處理,故而即便自布料W之背面側觀察時,針腳紋路之淩亂亦非常少,從而可獲得外觀較佳之縫製品質狀況。 Further, since the stitch end portion NTa is sewn into the stitch A in parallel or substantially parallel with the respective stitches NTb, even when viewed from the back side of the cloth W, the stitching of the stitches is extremely small, and the appearance can be obtained. The quality of the finished product is better.
進而,在將凸出於布料W之表面Wf上之針線端部分NTa於第2針以後之縫製動作時朝縫製行進方向Y之下游側以壓倒狀態移動導引時,可藉由該被壓倒移動導引之針線端部分NTa而使線鉤線端部分LTa亦一同被壓倒,並縫入針腳A中,抑制線鉤線端部分LTa自針腳A朝側方較大地露出,從而可獲得外觀更佳之縫製品質狀況。 Further, when the needle thread end portion NTa protruding from the surface Wf of the cloth W is moved in the overwhelming state toward the downstream side of the sewing traveling direction Y during the sewing operation after the second stitch, the overwhelming movement can be performed by the overwhelming movement. The needle end portion NTa is guided so that the wire hook end portion LTa is also pressed together and sewn into the stitch A, and the line hook end portion LTa is prevented from being largely exposed from the stitch A toward the side, so that a better appearance can be obtained. Sewing product quality.
