Description
本發明係關於一種縫紉機之布料派送輔助引導裝置,其係裝備於縫紉機主體而引導布料之強制派送,該縫紉機主體具備:布料派送裝置,其將例如裁斷為內衣之袖部之展開形狀的布料對折,將該對折布料沿上下重疊之上下布料部分之線狀端緣部之長度方向向既定之縫製進行方向強制派送;及縫製部,其以藉由該布料派送裝置沿既定之縫製進行方向強制派送之布料之線狀縫製端緣部成為既定形狀之方式切斷(切齊)該線狀端緣部,並且對切斷後之線狀縫製端緣部進行縫製。 The present invention relates to a cloth delivery auxiliary guide device for a sewing machine, which is provided on a sewing machine main body to guide the forced delivery of the cloth. The sewing machine main body is provided with a cloth delivery device that folds, for example, a cloth cut into an unfolded shape of a sleeve portion of underwear. , Forcing the double-folded fabric to be forcedly distributed in the predetermined sewing direction along the length direction of the linear end edge portion of the upper and lower cloth portions overlapping each other; and the sewing section forcibly being distributed in the predetermined sewing direction by the fabric distribution device The thread-shaped sewing end edge portion of the cloth is cut (cut into pieces) such that the thread-shaped sewing end edge portion has a predetermined shape, and the thread-shaped sewing end edge portion after the cutting is sewn.
圖10係例如為了形成袖部而被裁斷為該袖部之展開形狀之布料W,於使用該布料W實際地形成袖部時,將上述裁斷之布料W沿圖10之虛線所示之線對折,於將該對折布料W設置於縫紉機主體之布板上並藉由布料派送裝置向既定之縫製進行方向強制派送時,以上下重疊之上下布料部分W1、W2各自之線狀端緣部W1e、W2e沿既定之縫製進行方向依序移動之方式引導強制派送,藉此利用切刀切斷線狀端緣部W1e、W2e之多餘之伸出部分等,並且利用縫紉機主體側之縫製部對該切斷後之上下布料部分W1、W2之線狀端緣部W1e、W2e進行縫製。藉此,形成既定形狀之袖部。 FIG. 10 shows, for example, a cloth W cut into the expanded shape of the sleeve in order to form a sleeve. When the sleeve is actually formed using the cloth W, the cut cloth W is folded in half along the line shown by the dotted line in FIG. 10. When the half-folded cloth W is set on the cloth plate of the main body of the sewing machine and forcedly delivered in a predetermined sewing direction by a cloth distributing device, the upper and lower cloth portions W1 and W2 respectively overlap the linear end edges W1e, W2e guides compulsory delivery by sequentially moving in the direction of the predetermined sewing progress direction, thereby cutting the extra protrusions of the linear end portions W1e, W2e, etc. with a cutter, and using the sewing section on the main body side of the sewing machine to cut After cutting, the linear end edges W1e and W2e of the upper and lower cloth portions W1 and W2 are sewn. Thereby, a sleeve portion having a predetermined shape is formed.
於上述袖部之形成時,於僅將被裁斷之布料W對折,縫製作業者以手直接握持該對折布料W引導強制派送之情形時,不僅對縫製作業者要求 較高之熟練度,而且即使為熟練度較高之縫製作業者,亦會受到手振或機械振動等之影響而難以穩定保持線狀端緣部W1e、W2e之派送位置。因此,切刀之切斷位置偏離、或蜿蜒,而無法獲得既定形狀之切斷布料,另外,切斷後之縫製中縫製位置亦不穩定,因此所形成之袖部等縫製品容易成為形狀上不得體而加工較差之不良品。 When the sleeve is formed, when only the cut fabric W is folded in half, and the sewing operator directly holds the folded fabric W with his hand to guide the forced delivery, not only the sewing operator is required to have a high degree of proficiency, but also Even if it is a highly skilled sewing operator, it is difficult to stably maintain the delivery positions of the linear end edges W1e and W2e due to the effects of hand vibration or mechanical vibration. Therefore, the cutting position of the cutter is deviated or meandered, and a cutting fabric of a predetermined shape cannot be obtained. In addition, the sewing position is also unstable during sewing after cutting. Therefore, the sewing products such as the sleeves are easily shaped. Indecent and poorly processed defective products.
作為抑制該加工不良品之產生之手段,習知提出有如圖11A、11B所示,使用被稱為導板之夾具引導布料之強制派送。該導板T以可將具有與對折布料W之上下布料部分W1、W2近似之形狀的上下一對塑膠製之型板T1、T2切換為如下兩種狀態之方式構成:以該等型板之寬度方向之一端部作為彎折支點而如圖11A所示般展開為平面狀之狀態;及如圖11B所示般摺疊為上下兩塊之狀態。另外,於下部型板T2之下表面以可藉由擺動下部型板T2而位置變更為寬度方向之兩個位置之方式安裝有布料端緣定位用板P,該兩個位置係:布料端緣定位用板P之端緣Pe較下部型板T2之端緣T2e更向外側突出之位置;及較下部型板T2之端緣T2e更向內側引退之位置。 As a means of suppressing the occurrence of this defective product, conventionally, as shown in Figs. 11A and 11B, a compulsory delivery of the cloth is guided by a jig called a guide plate. The guide plate T is configured to switch a pair of upper and lower plastic mold plates T1 and T2 having a shape similar to the upper and lower cloth portions W1 and W2 of the folded cloth W to the following two states: One end portion in the width direction serves as a bending fulcrum and is expanded into a flat state as shown in FIG. 11A; and a state where it is folded into two pieces as shown in FIG. 11B. In addition, a cloth edge positioning plate P is installed on the lower surface of the lower template T2 so that the position can be changed to two positions in the width direction by swinging the lower template T2. The two positions are: the cloth edge A position where the end edge Pe of the positioning plate P protrudes more outwardly than the end edge T2e of the lower profile plate T2; and a position retracted more inward than the end edge T2e of the lower profile plate T2.
然後,如圖11A所示,於將上述上下一對型板T1、T2展開為平面狀之狀態下,將裁斷為袖部之展開形狀之布料W載置於該等一對型板T1、T2之展開平面上。此時,上述布料端緣定位用板P係變更為較下部型板T2之端緣T2e更向外側突出之位置,使布料W之端緣W2e與下部型板T2之端緣T2e之位置對準。 Then, as shown in FIG. 11A, in a state where the above-mentioned pair of upper and lower profiles T1 and T2 are unfolded into a flat shape, the cloth W cut into the expanded shape of the sleeve is placed on the pair of profiles T1 and T2. On the unfolded plane. At this time, the cloth edge positioning plate P is changed to a position protruding more outward than the edge T2e of the lower profile T2, so that the position of the edge W2e of the cloth W and the edge T2e of the lower profile T2 are aligned. .
於該狀態下,藉由將導板T之上下一對型板T1、T2以如圖11B所示之方式摺疊,而將上述布料W對折,使上下重疊之上下布料部分W1、W2夾持保持於上下一對型板T1、T2間。該被夾持保持之對折布料W之上下布料部分W1、W2之線狀端緣部W1e、W2e成為與上部型板T1之端緣T1e及下部型板T2之端緣T2e相比稍微向外側露出之狀態。 In this state, by folding the pair of profile plates T1 and T2 above and below the guide plate T as shown in FIG. 11B, the above-mentioned cloth W is folded in half, so that the upper and lower cloth portions W1 and W2 are overlapped and held. Between the upper and lower pair of profiles T1 and T2. The linear edge portions W1e and W2e of the upper and lower cloth portions W1 and W2 of the half-folded cloth W held and held are slightly exposed to the outside compared to the edge T1e of the upper profile T1 and the edge T2e of the lower profile T2. Of the state.
如上所述,於使用將對折之布料W夾持保持於上下一對型板T1、T2間之導板T引導布料W之強制派送之情形時,與縫製作業者直接以手握持柔軟之布料W進行引導之情形相比,容易處理,並且可穩定地導引布料之線狀端緣部之派送位置,抑制切斷位置之偏離或蜿蜒,另一方面,由於必須以手穩固地保持導板T,因此依然無法避免手振或機械振動等之影響導致之切斷位置及縫製位置之偏離或蜿蜒的產生,其結果為存在無法確實地獲得形狀得體且加工良好之縫製品之問題。 As described above, when the cloth W that is folded in half is clamped and held by the guide plate T between the pair of upper and lower profiles T1 and T2 to guide the forced delivery of the cloth W, the sewing cloth is directly held by the sewing operator with the hand Compared with the case of W, it is easier to handle, and it can stably guide the delivery position of the linear end edge of the cloth to prevent deviation or meandering of the cutting position. On the other hand, it is necessary to keep the guide firmly by hand. As for the plate T, it is still unavoidable that the cutting position and the sewing position are deviated or meandered due to the influence of hand vibration or mechanical vibration. As a result, there is a problem that a properly shaped and well-processed sewing product cannot be obtained.
本發明係鑒於上述實際情況而完成者,其目的在於提供一種縫紉機之布料派送輔助引導裝置,該縫紉機之布料派送輔助引導裝置可與縫製作業者之熟練度無關地穩定地導引布料之線狀端緣部之派送位置,消除由切斷位置及縫製位置之偏離或蜿蜒引起之異常,而以既定形狀確實且穩定地形成得體之縫製品。 The present invention has been made in view of the above-mentioned actual circumstances, and an object thereof is to provide a cloth distribution auxiliary guide device for a sewing machine, which can stably guide the thread shape of cloth regardless of the proficiency of a sewing operator. The delivery position of the edge part eliminates the abnormality caused by the deviation or winding of the cutting position and the sewing position, and forms a proper and stable sewing product with a predetermined shape.
為了達成上述目的,本發明之縫紉機之布料派送輔助引導裝置係裝備於縫紉機主體而引導型板及布料之強制派送,該縫紉機主體具備:布料派送裝置,其將於線狀縫製端緣部露出之狀態下夾持保持於上下一對型板間之布料與上述上下一對型板一起向既定之縫製進行方向強制派送;及縫製部,其對藉由該布料派送裝置沿既定之縫製進行方向強制派送之布料之從上述型板露出之線狀縫製端緣部進行縫製,該縫紉機之布料派送輔助引導裝置之特徵在於:於上述上下一對型板中,於上部型板形成有跨上述布料之線狀縫製端緣部之至少總長而與該線狀縫製端緣部平行或大致平行之導軌部,另一方面,於上 述縫紉機主體側設置有派送引導體,該派送引導體以於利用上述布料派送裝置進行型板及布料之強制派送時與上述上部型板之導軌部嵌合或抵接以避免上述布料之線狀縫製端緣部從上述縫紉機主體之縫製部脫離之方式進行派送引導。 In order to achieve the above object, the cloth distribution auxiliary guide device of the sewing machine of the present invention is equipped with a sewing machine main body to guide the forced distribution of the template and the cloth. The main body of the sewing machine is provided with a cloth distribution device which is exposed at the end of the thread-shaped sewing. The fabric clamped and held between the pair of upper and lower profiles in the state is forcibly distributed in the predetermined sewing direction together with the pair of upper and lower profiles; and the sewing unit is configured to force the fabric distribution device to perform the predetermined sewing direction. The thread-shaped sewing end edge of the cloth to be distributed is sewed from the above-mentioned template. The cloth distribution auxiliary guide device of the sewing machine is characterized in that: in the above-mentioned pair of upper and lower templates, an upper template is formed to span the above-mentioned cloth. At least the total length of the linear sewing end edge portion is at least the total length of the rail portion parallel or substantially parallel to the linear sewing end edge portion. On the other hand, a sewing guide body is provided on the main body side of the sewing machine, and the distribution guide body is used for the cloth. The distribution device fits or abuts on the guide part of the upper mold plate when the template and the cloth are forcibly delivered to avoid the cloth. The thread-like sewing end edge portion of the material is separated from the sewing portion of the sewing machine main body so as to be delivered and guided.
藉由具有如上所述之特徵之本發明的縫紉機之布料派送輔助引導裝置,於在線狀端緣部露出之狀態下藉由布料派送裝置將夾持保持於上下一對型板間之布料向既定之縫製進行方向強制派送時,可以使設置於縫紉機主體側之派送引導體與形成於上部型板之導軌部嵌合或抵接以避免從上述一對型板露出之布料之線狀端緣部從縫紉機主體之縫製部脫離之方式將型板及布料以機械方式派送引導。因此,與縫製作業者以手直接握持布料進行派送引導之情形或使用夾持保持布料之型板而縫製作業者以手派送引導該型板之情形相比,不僅可大幅減少縫製作業者之作業工時,而且可與縫製作業者之熟練度無關地穩定地導引布料之線狀端緣部之派送位置,減少由端緣部之切斷位置及縫製位置之偏離或蜿蜒引起之異常之產生。因此,發揮出可確實且穩定地形成形狀得體之縫製品之效果。 With the cloth distribution assisting guide device of the sewing machine of the present invention having the above-mentioned characteristics, the cloth distribution device is used to hold and hold the cloth held between the pair of upper and lower profiles in a state where the linear end portion is exposed. For forced delivery in the sewing direction, the delivery guide provided on the main body side of the sewing machine can be fitted or abutted against the rail portion formed on the upper template to avoid the linear end edge of the cloth exposed from the pair of templates. The stencil and cloth are mechanically distributed and guided away from the sewing part of the main body of the sewing machine. Therefore, compared with a case where the sewing operator directly holds the fabric with his hand for delivery guidance, or a case where the sewing operator uses the gripper to hold the fabric and guide the template by hand, the sewing operator's Working hours, and can stably guide the delivery position of the linear end edge of the fabric regardless of the proficiency of the sewing operator, reducing the abnormality caused by the deviation or winding of the cutting position of the end edge and the sewing position To produce. Therefore, an effect is obtained in which a suitably shaped sewing product can be formed reliably and stably.
於本發明之縫紉機之布料派送輔助引導裝置中,較佳為上述上部型板之導軌部由從該上部型板向上方突出形成之凸條之導軌部所構成,並且上述縫紉機主體側之派送引導體由旋轉體所構成,該旋轉體係抵接於上述凸條之導軌部之側面且可伴隨型板之強制派送而繞上下軸心旋轉,於該旋轉體之旋轉支承部與裝置固定部之間介裝有彈性體,該彈性體以避免上述布料之線狀縫製端緣部從上述縫紉機主體之縫製部脫離之方式將上述型板朝上述縫製部側彈性地按壓。 In the cloth distribution assisting guide device of the sewing machine of the present invention, it is preferable that the guide rail portion of the upper mold plate is composed of a guide rail portion of a ridge protruding from the upper mold plate and the distribution guide of the sewing machine main body side. The body is composed of a rotating body. The rotating system is in contact with the side of the guide portion of the convex strip and can rotate about the upper and lower axes along with the forced distribution of the template. Between the rotating support portion and the device fixing portion of the rotating body An elastic body is interposed, and the elastic plate is elastically pressed toward the sewing portion side so that the thread-shaped sewing end edge portion of the cloth is not detached from the sewing portion of the sewing machine body.
於該情形時,由於一對型板及夾持保持於該型板之布料之派送引導係旋轉體抵接於導軌部之側面且伴隨型板之強制派送而旋轉體繞上下軸心旋轉,因此 可確實、穩定且阻力亦較少而順利地進行布料之派送引導作用。 In this case, since the pair of profile plates and the delivery guide system holding the cloth held on the profile plate are abutted against the side of the guide rail portion and the forced delivery of the profile plates rotates the rotary body around the upper and lower axes, The cloth can be guided reliably, stably, and with little resistance.
另外,於本發明之縫紉機之布料派送輔助引導裝置中,較佳為沿縫製進行方向隔開適當間隔而配置複數個構成上述縫紉機主體側之派送引導體之旋轉體,該等複數個旋轉體以分別經由不同之彈性體抵接於上述凸條之導軌部之側面而將上述型板朝上述縫製部側彈性地按壓之方式構成。 In addition, in the cloth distribution assisting guide device of the sewing machine of the present invention, it is preferable to arrange a plurality of rotating bodies constituting the above-mentioned sewing guide body on the sewing machine body at appropriate intervals in the sewing progress direction. Each of the elastic members is configured to abut the side surface of the guide rail portion of the convex strip and elastically press the template toward the sewing portion side through different elastic bodies.
於該情形時,藉由作為沿縫製進行方向隔開適當間隔所配置之複數個派送引導體之旋轉體分別抵接於導軌之側面而將型板朝縫製部側彈性地按壓,即使布料之線狀端緣部為於其長度方向上整體彎曲者或一部分具有曲線者,亦可維持複數個旋轉體應對該等彎曲或曲線而分別獨立地抵接於導軌之側面之狀態,藉此,可一直穩定地進行型板及布料之線狀端緣部之派送引導作用,而可有效地用於具有多種形狀之線狀端緣部之布料的縫製。 In this case, by rotating the plurality of delivery guides arranged at appropriate intervals in the sewing progress direction, the rotary bodies abut against the sides of the guide rails respectively, and the template is elastically pressed toward the sewing portion side, even if the fabric thread The shape of the edge portion is a person that is curved in its entirety or has a part of the curve. It can also maintain a state in which a plurality of rotating bodies are in abutment with the sides of the guide rail in response to these curves or curves. It can stably guide the linear end edge of the profile and the fabric, and can be effectively used for sewing fabrics with linear end edges of various shapes.
另外,於本發明之縫紉機之布料派送輔助引導裝置中,較佳為上述彈性體為彈簧,於上述旋轉體之外周面捲繞有彈性圈。 Moreover, in the cloth distribution assisting guide device of the sewing machine of the present invention, it is preferable that the elastic body is a spring, and an elastic ring is wound around an outer peripheral surface of the rotating body.
於該情形時,由於旋轉體本身亦被捲繞於其外周部之彈性圈向導軌部按壓,因此即使增強彈簧對導軌部之彈性壓力,亦可減少由旋轉體與導軌部之滑動接觸摩擦引起之導軌部之磨耗而長期穩定地保持初期之派送引導作用。 In this case, since the rotating body itself is also pressed against the guide rail portion by the elastic ring wound around its outer peripheral portion, even if the elastic pressure of the spring on the guide rail portion is enhanced, the sliding contact friction caused by the rotating body and the guide rail portion can be reduced. The abrasion of the guide rail part can stably maintain the initial delivery guidance for a long time.
進而,於本發明之縫紉機之布料派送輔助引導裝置中,較佳為設置有輔助派送裝置,其與由上述派送引導體派送引導後之上述上部型板接觸而將上下一對型板及布料向既定之縫製進行方向移送。 Further, in the cloth distribution auxiliary guide device of the sewing machine of the present invention, it is preferable to provide an auxiliary distribution device which contacts the upper template after being guided by the distribution guide body to direct the upper and lower pair of templates and cloth to The predetermined sewing moves in the direction.
於該情形時,可將縫製結束之布料及型板向既定之縫製進行方向迅速移送而謀求提高縫製作業之效率。 In this case, it is possible to quickly transfer the finished fabric and pattern to the predetermined sewing progress direction to improve the efficiency of the sewing operation.

其次,對使用以上述方式構成之本實施形態之雙針式拷克機M、布料派送輔助引導裝置G及導板T形成例如內衣之袖部之縫製動作進行說明。 Next, a sewing operation for forming, for example, a sleeve portion of underwear using the two-needle pincher M of the present embodiment configured as described above, the cloth distribution assisting guide device G, and the guide plate T will be described.
首先,作為縫製前之準備階段,將裁斷為袖部之展開形狀之布料對折並夾持保持於導板T。具體而言,如圖7A所示,於將上述導板T之一對型板T1、T2展開為平面狀之狀態下,將裁斷為袖部之展開形狀之布料W載置於該等一對型板T1、T2之展開平面上。此時,上述布料端緣定位用板P係變更為 較下部型板T2之端緣T2e更向外側突出之位置,使布料W之端緣W2e與下部型板T2之端緣T2e之位置對準。 First, as a preparation stage before sewing, the cloth cut into the unfolded shape of the sleeve is folded in half and held on the guide plate T. Specifically, as shown in FIG. 7A, in a state where one of the pair of profile plates T1 and T2 of the guide plate T is unfolded into a flat shape, the cloth W cut into the unfolded shape of the sleeve is placed on the pair. On the unfolding plane of the templates T1 and T2. At this time, the cloth edge positioning plate P is changed to a position protruding more outward than the edge T2e of the lower profile T2, so that the position of the edge W2e of the cloth W and the edge T2e of the lower profile T2 are aligned. .
於該狀態下,如圖7B所示,將導板T之上下一對型板T1、T2摺疊,藉此將上述布料W對折而將上下重疊之上下布料部分W1、W2夾持保持於上下一對型板T1、T2間。該夾持保持之對折布料W之上下布料部分W1、W2之線狀端緣部W1e、W2e成為與上部型板T1之端緣T1e及下部型板T2之端緣T2e相比稍微向外側露出之狀態。 In this state, as shown in FIG. 7B, the pair of profile plates T1 and T2 above and below the guide plate T are folded, thereby folding the above-mentioned cloth W in half and sandwiching the upper and lower cloth portions W1 and W2 that are overlapped on the upper and lower sides. Between the profile plates T1 and T2. The linear edge portions W1e and W2e of the upper and lower cloth portions W1 and W2 of the half-folded cloth W held by this clamp are slightly exposed to the outside compared with the edge T1e of the upper profile T1 and the edge T2e of the lower profile T2. status.
其次,於圖1及圖2所示之狀態下,將夾持保持有上述對折布料W之導板T設置於壓布板8下之縫製部10,成為發揮利用布料派送輔助引導裝置G之既定之布料派送輔助引導功能的狀態。 Next, in the state shown in FIG. 1 and FIG. 2, the guide plate T holding and holding the above-mentioned folded cloth W is set at the sewing portion 10 under the press plate 8, and it becomes a predetermined use of the cloth distribution auxiliary guide device G. The state of the cloth delivery assistance guidance function.
於該狀態下,開始雙針式拷克機M之旋轉作動,藉此上述導板T被作用於其下部型板T2之下表面之推布齒與作用於其上部型板T1之上表面之壓板8朝縫製進行方向Y間歇性地強制移送,同時伴隨縫紉機M之旋轉作動而藉由左右2根針6之上升下降動作等一系列縫製動作,利用上切刀9將從導板T露出之布料W之上下布料部分W1、W2的線狀端緣部W1e、W2e之多餘之伸出部分等切斷,並且利用縫紉機主體1側之縫製部10對該切斷後之上下布料部分W1、W2之線狀端緣部W1e、W2e進行縫製,藉此形成既定形狀之袖部,藉由與導板T之上部型板T1之上表面接觸之輔助派送裝置13,將該形成之袖部朝既定之縫製進行方向Y之後方送出。 In this state, the rotation operation of the two-needle copying machine M is started, whereby the above-mentioned guide plate T is pushed by the pushing cloth teeth on the lower surface of the lower mold plate T2 and on the upper surface of the upper mold plate T1. The pressure plate 8 is intermittently forcibly moved in the sewing direction Y, and at the same time, a series of sewing operations such as the rising and falling movements of the two left and right needles 6 are performed along with the rotation of the sewing machine M, and the upper blade 9 is used to expose the The linear end edges W1e and W2e of the upper and lower cloth portions W1 and W2 of the cloth W are cut off, and the sewing portion 10 on the sewing machine main body 1 is used to cut the upper and lower cloth portions W1 and W2. The linear end edges W1e and W2e are sewn to form a sleeve of a predetermined shape, and the auxiliary sleeve 13 is in contact with the upper surface of the guide plate T and the upper surface of the profile plate T1, and the formed sleeve is directed toward the predetermined one. Send it after sewing direction Y.
於如上所述之袖部之縫製時,於在線狀端緣部W1e、W2e露出之狀態下藉由推布齒將於上下一對型板T1、T2間夾持保持有布料W之導板T向既定之縫製進行方向Y強制派送時,設置於縫紉機主體1側之兩個旋轉體12A、12B抵接於形成於上述導板T之上部型板T1之導軌部GR之側面而經由彈簧17A、17B將上述導板T朝上述縫製部10側彈性地按壓,藉此可以避免從上述一 對型板T1、T2露出之布料之線狀端緣部W1e、W2e從縫紉機主體1之縫製部10脫離之方式將導板T及布料W以機械方式派送引導。 During the sewing of the sleeves as described above, the guide plate T holding the cloth W is held between the upper and lower pair of profile plates T1 and T2 by the pusher teeth while the linear end edges W1e and W2e are exposed. When forcibly delivering in the predetermined sewing direction Y, the two rotating bodies 12A and 12B provided on the sewing machine main body 1 side abut on the side of the rail portion GR formed on the guide plate T above the profile plate T1 and pass through the spring 17A, 17B By pressing the guide plate T elastically toward the sewing portion 10 side, it is possible to prevent the linear end edges W1e and W2e of the cloth exposed from the pair of profile plates T1 and T2 from being separated from the sewing portion 10 of the sewing machine main body 1. In this way, the guide plate T and the cloth W are mechanically distributed and guided.
藉此,與縫製作業者以手直接握持布料進行派送引導之情形或使用夾持保持布料之型板而縫製作業者以手派送引導該型板之情形相比,不僅可大幅減少縫製作業者之作業工時,而且可與縫製作業者之熟練度無關地穩定地導引布料W之線狀端緣部W1e、W2e之派送位置,減少由該線狀端緣部之切斷位置及縫製位置之偏離或蜿蜒引起之異常之產生,因此可確實且穩定地形成形狀得體之縫製品。 As a result, compared with the case where the sewing operator directly holds the fabric with his hand for delivery guidance, or the case where the sewing operator uses the template to hold and hold the fabric for manual delivery, the sewing operator can greatly reduce the number of sewing operators. The man-hours can stably guide the delivery positions of the linear end edges W1e and W2e of the cloth W regardless of the proficiency of the sewing operator, and reduce the cutting position and sewing position of the linear end edges. The abnormality caused by the deviation or meandering can form a properly shaped sewing product reliably and stably.
尤其是如上述實施形態所說明般,於縫紉機主體1側之派送引導體由抵接於形成於導板T之凸條之導軌部GR之側面且可伴隨導板T之強制派送而繞上下軸心旋轉之旋轉體12A、12B構成之情形時,由於導板T及夾持保持於該導板T之布料W之派送引導係旋轉體12A、12B抵接於導軌部GR之側面且伴隨強制派送而繞上下軸心旋轉,因此可確實、穩定且阻力亦較少而順利地進行布料之派送引導作用。 In particular, as described in the above embodiment, the delivery guide on the sewing machine main body 1 is abutted on the side of the guide rail portion GR formed on the rib of the guide plate T and can be wound around the upper and lower shafts along with the forced delivery of the guide plate T. In the case of a rotary body 12A, 12B that rotates with the heart, the guide plate T and the delivery guide system holding the cloth W held by the guide plate T are rotated against the side of the guide rail GR with the mandatory delivery 12A, 12B. And it rotates around the upper and lower axes, so that the cloth can be guided smoothly, reliably, stably, and with less resistance.
另外,沿縫製進行方向隔開適當間隔而配置複數個、本實施形態中為2個上述旋轉體,藉由以分別經由不同之彈簧17A、17B分開抵接於上述凸條之導軌部GR之側面而將上述導板T朝上述縫製部10側彈性地按壓之方式構成該等2個旋轉體12A、12B,即使布料之線狀端緣部為於其長度方向上整體彎曲者或一部分具有曲線者,亦可維持2個旋轉體12A、12B應對該等彎曲或曲線而分別獨立地抵接於導軌部GR之側面之狀態,藉此,可一直穩定地進行導板T及布料W之線狀端緣部之派送引導作用,而可有效地用於具有多種形狀之線狀端緣部之布料的縫製。 In addition, a plurality of the rotating bodies are arranged at appropriate intervals in the sewing progress direction, and in the present embodiment, the two rotating bodies are respectively abutted against the side surfaces of the guide rail portion GR of the ridges through different springs 17A and 17B, respectively. The two rotating bodies 12A and 12B are formed by elastically pressing the guide plate T toward the sewing portion 10 side, even if the linear end edge portion of the cloth is curved in its entire length or a portion has a curve. It is also possible to maintain the state where the two rotating bodies 12A and 12B abut on the side of the guide rail GR independently of each other in response to such bends or curves, whereby the linear ends of the guide plate T and the cloth W can be stably performed at all times. The edge guide function can be effectively used to sew fabrics with linear end edges with various shapes.
進而,如上述實施形態亦說明般,藉由以於派送引導用之上述旋轉體12A、12B之外周面捲繞由橡膠構成之彈性圈19A、19B,使上述導軌部 GR之側面彈性地抵接於該彈性圈19A、19B之外周面之方式構成,由於旋轉體12A、12B本身亦被捲繞於其外周部之彈性圈19A、19B向導軌部GR按壓,因此即使增強彈簧17A、17B對導軌部GR之彈性壓力,即使塑膠製之導軌部GR為塑膠製,亦可抑制由該導軌部GR與旋轉體12A、12B之滑動接觸摩擦引起之導軌部GR之磨耗,而可長期穩定地保持初期之派送引導作用。 Furthermore, as described in the above-mentioned embodiment, the elastic body 19A, 19B made of rubber is wound around the outer peripheral surface of the rotating bodies 12A, 12B for delivery guidance, so that the side surfaces of the guide rail GR are elastically abutted. The elastic rings 19A and 19B are structured on the outer peripheral surface. Since the rotating bodies 12A and 12B are also pressed by the elastic rings 19A and 19B wound on the outer peripheral part of the elastic rings 19A and 19B toward the guide rail GR, even if the springs 17A and 17B reinforce the guide rails, The elastic pressure of the part GR can suppress the abrasion of the guide rail GR caused by the sliding contact friction between the guide rail GR and the rotating bodies 12A and 12B even if the plastic guide rail GR is made of plastic, and the initial stage can be stably maintained for a long time. The role of delivery guidance.
再者,於上述實施形態中,對導軌部GR由從上部型板T1之上表面向上方突出形成之凸條之導軌部構成者進行了說明,但亦可形成凹槽狀之導軌部,而使用嵌合於該凹槽狀導軌部內並旋轉之輥作為派送引導體。 Furthermore, in the above-mentioned embodiment, the guide rail portion GR is described by a guide rail portion formed by a protruding portion protruding upward from the upper surface of the upper mold plate T1. However, a groove-shaped guide rail portion may be formed. As the delivery guide, a roller fitted in the groove-shaped guide portion and rotated is used.
