Description
本發明是關於縫紉機，該縫紉機適用於作業者使手接近落針部的附近進行縫製作業的情況。 The present invention relates to a sewing machine which is suitable for a case where an operator performs a sewing operation by approaching a hand near a needle drop portion.
以往，例如日本國特開平10-235054號公報所記載，一種縫紉機，在與落針部相比較靠近跟前側具有布料折回裝置。該布料折回裝置具有：能夠在左右方向上移動的板狀的引導部；位於引導部的右方且具有與引導部對應的彎曲面的規尺部；通過空氣壓對布料進行施力的空氣噴嘴。在引導部和規尺部以規定間隔接近的狀態下，通過從空氣噴嘴噴出的氣流，能夠在引導部的右端部和規尺部的彎曲面之間使布料折回。折回的布料被送到落針部進行縫製。 In the sewing machine, a sewing machine has a fabric folding back device closer to the front side than the needle drop portion, as described in Japanese Laid-Open Patent Publication No. Hei 10-235054. The fabric folding back device has a plate-shaped guide portion that is movable in the left-right direction, a ruler portion that is located on the right side of the guide portion and has a curved surface corresponding to the guide portion, and an air nozzle that biases the cloth by air pressure. . In a state where the guide portion and the ruler portion are close to each other at a predetermined interval, the cloth can be folded back between the right end portion of the guide portion and the curved surface of the ruler portion by the air flow ejected from the air nozzle. The folded fabric is sent to the needle drop portion for sewing.
在具有該布料折回裝置的縫紉機中，需要將用於使引導部左右移動的驅動機構等設置在縫紉機座上。因此，如日本國特開平10-235054號公報的圖1所示，驅動機構等位於縫紉機座的跟前側。 In the sewing machine having the cloth folding device, it is necessary to provide a driving mechanism or the like for moving the guide portion to the left and right on the sewing machine base. Therefore, as shown in Fig. 1 of Japanese Laid-Open Patent Publication No. Hei 10-235054, the drive mechanism and the like are located on the front side of the sewing machine base.
在此，布料折回裝置的驅動機構等位於縫紉機座的跟前側的情況下，由於該驅動機構等的妨礙，作業者難以將手伸到落針部的周圍。因此，由於作業者在將布料放置在落針部上時，難以使開始縫製布料的位置與落針部一致，可能導致縫製效率降低。該情況尤其在用於大量縫製衣料的工業用縫紉機中成為較大的問題。 Here, when the drive mechanism or the like of the cloth folding device is located on the front side of the sewing machine seat, it is difficult for the operator to extend the hand to the periphery of the needle drop portion due to the hindrance of the drive mechanism or the like. Therefore, when the operator places the cloth on the needle drop portion, it is difficult to make the position at which the sewing of the cloth is started coincide with the needle drop portion, which may result in a decrease in the sewing efficiency. This situation is a major problem especially in industrial sewing machines for sewing a large amount of clothing.
另外，還有一種縫紉機，除了具有上述布料折回裝置，還設有：布料端部切斷裝置，在與落針部相比較靠近跟前側，能夠在縫製動作中對被折回的布料的端緣進行切斷；吸引裝置，用於對藉由上述布料端部切斷裝置所切斷的布料片進行吸入。以上的縫紉機中，由於存在布料端部切斷裝置及吸引裝置，縫紉機座的與落針部相比較靠近跟前側的尺寸變大，所以，上述問題變得更加顯著。 Further, there is a sewing machine which, in addition to the above-mentioned fabric folding device, is provided with a cloth end cutting device which is closer to the front side than the needle dropping portion, and is capable of performing the edge of the folded fabric in the sewing operation. The cutting device is configured to suck the cloth piece cut by the cloth end cutting device. In the above-described sewing machine, since the cloth end cutting device and the suction device are present, the size of the sewing machine seat closer to the front side than the needle drop portion becomes larger, and the above problem becomes more remarkable.

Therefore, it is possible to reduce the adjustment of the thread tension or perform maintenance. Interference. Further, when the maintenance is actually performed, the other parts that can be opened in the sewing machine bed 2a are also opened.
基板部41中，從針板21的向跟前側的延長位置到近右側的規定範圍，將上端切出開口成為正面方向顯示大致長方形狀。該切開的部分為凹部46。因此，凹部46在比落針部21a更近跟前側朝跟前方向及上方開放。本實施形態中，凹部46的左端位在比針板21的左端更左方。另外，在以落針部21a的向跟前側的延長位置為基準的情況下，凹部46形成為距右端的距離大於距凹部46的左端的距離。因此，即使在作業者的右手相對於落針部21a位於右側的情況下，也能夠容易地將該右手伸入到凹部46中。 In the board portion 41, from the extended position of the needle plate 21 toward the front side to a predetermined range on the right side, the upper end cut-out opening is formed into a substantially rectangular shape in the front direction. The cut portion is a recess 46. Therefore, the concave portion 46 is opened closer to the front direction and above than the needle drop portion 21a. In the present embodiment, the left end of the concave portion 46 is located to the left of the left end of the needle plate 21. Further, in the case where the extended position of the needle drop portion 21a toward the front side is used as a reference, the concave portion 46 is formed such that the distance from the right end is larger than the distance from the left end of the concave portion 46. Therefore, even when the right hand of the operator is positioned on the right side with respect to the needle drop portion 21a, the right hand can be easily inserted into the recess 46.
另外，本實施形態中，與凹部46的跟前側連續地設有向跟前側下降的傾斜部47。本實施形態的傾斜部47具有向上方呈凹狀的彎曲面。該傾斜部47設置用於容易將作業者的手引導至凹部46。此外，本實施形態的傾斜部47與凹部46雖是分別形成，但不限於此，如圖6B、圖6C所示，還能夠作為凹部46的一部分形成傾斜部462。 Further, in the present embodiment, the inclined portion 47 that descends toward the front side is provided continuously with the front side of the recessed portion 46. The inclined portion 47 of the present embodiment has a curved surface that is concave upward. This inclined portion 47 is provided for easily guiding the operator's hand to the recess 46. Further, although the inclined portion 47 and the concave portion 46 of the present embodiment are formed separately, the present invention is not limited thereto, and as shown in FIGS. 6B and 6C, the inclined portion 462 can be formed as a part of the concave portion 46.
例如，如圖6B所示，能夠列舉如：形成有位於凹部46後方側的作為水平面的平面部461，及與該平面部461的跟前側連續地定取，並向跟前側下降的作為傾斜平面的傾斜部462。另外，如圖6C所示，能夠列舉形成有與圖6B相同的平面部461，及與該平面部461的跟前側連續，並朝跟前側下降的作為彎曲面的傾斜部462。除此之外，雖未圖示，還能夠將傾斜部462形成為集合隨著向跟前側逐漸下降的多個面的形態，例如形成為臺階狀。 For example, as shown in FIG. 6B, a flat portion 461 as a horizontal surface on the rear side of the concave portion 46, and a front surface which is continuously positioned with the front side of the flat portion 461 and which is lowered toward the front side as an inclined plane can be cited. The inclined portion 462. In addition, as shown in FIG. 6C, the flat portion 461 which is the same as that of FIG. 6B and the inclined portion 462 which is continuous with the front side of the flat portion 461 and which is lowered toward the front side can be used. In addition, although not shown, the inclined portion 462 can be formed in a stepped shape, for example, in a form in which a plurality of faces gradually descend toward the front side.
凹部46形成在基板部41上，所以，能夠將凹部46與布料折回裝置4一起形成。因此，容易形成凹部46。另外，如圖3所示，維護時將基板部41向跟前側傾倒，可藉此將凹部46從縫紉機座2a分離而將縫紉機1的跟前側大範圍地開放。因此，能夠減少進行縫紉機1的維護等時的妨礙。 Since the concave portion 46 is formed on the substrate portion 41, the concave portion 46 can be formed together with the cloth folding back device 4. Therefore, the concave portion 46 is easily formed. Further, as shown in FIG. 3, the substrate portion 41 is tilted toward the front side during maintenance, whereby the concave portion 46 can be separated from the sewing machine holder 2a, and the front side of the sewing machine 1 can be widely opened. Therefore, it is possible to reduce the hindrance when the maintenance of the sewing machine 1 or the like is performed.
如上述在布料折回裝置4的基板部41形成有凹部46，由此，在布料折回裝置4的引導部42的右側及規尺部43的左側確保了空間。而且，在引導部42及規尺部43的跟前側也確保了空間。因此，難以發生以往設在縫紉機座的用於使引導部移動的驅動機構等成為妨礙的情況，作業者容易將手靠近落針部21a。 As described above, the concave portion 46 is formed in the substrate portion 41 of the cloth folding device 4, whereby the space is secured to the right side of the guide portion 42 of the cloth folding device 4 and the left side of the ruler portion 43. Further, a space is also secured to the front side of the guide portion 42 and the gauge portion 43. Therefore, it is difficult to cause the drive mechanism or the like which is conventionally provided in the sewing machine seat to move the guide portion, and it is difficult for the operator to bring the hand closer to the needle drop portion 21a.
此外，本實施形態中，雖在基板部41形成有凹部46，但不限於此。例如，在不設置基板部41的情況下，能夠在構成布料折回裝置4的其他構件形成凹部46，還能夠在基板部41與其他構件的組合中形成凹部46。另 外，凹部46在本實施形態中形成為左端、右端、下端被封閉的形狀(横倒的大致“”字型或大致U字型)，但不限於此，還可以是數個端部開放的形状(例如，大致L字型)。 Further, in the present embodiment, the concave portion 46 is formed in the substrate portion 41, but the invention is not limited thereto. For example, when the substrate portion 41 is not provided, the concave portion 46 can be formed in another member constituting the cloth folding device 4, and the concave portion 46 can be formed in combination with the other member. Further, in the present embodiment, the recessed portion 46 is formed in a shape in which the left end, the right end, and the lower end are closed (subjected substantially). The "font type or the substantially U shape" is not limited thereto, and may be a plurality of shapes whose ends are open (for example, a substantially L shape).
此外，本實施形態中，布料折回裝置4的驅動氣缸45安裝在基板部41的下方。亦即，由於驅動氣缸45是較凹部46位於下方，因此在作業者將手接近落針部21a時不會造成妨礙。 Further, in the present embodiment, the drive cylinder 45 of the cloth folding back device 4 is attached below the substrate portion 41. That is, since the drive cylinder 45 is located below the recessed portion 46, there is no hindrance when the operator approaches the needle drop portion 21a.
如上述，在本實施形態的縫紉機1中，作業者容易將手接近落針部21a，因此，在作業者將折回成兩層的布料設定於落針部21a時，能夠容易地使開始縫製布料的位置與落針部21a一致，能夠抑制縫製效率的降低。尤其對於縫紉機1是用於大量縫製服裝的工業用縫紉機的情況是有利的。 As described above, in the sewing machine 1 of the present embodiment, the operator can easily approach the needle drop portion 21a. Therefore, when the operator sets the fabric folded back into two layers to the needle drop portion 21a, the cloth can be easily started to be sewn. The position coincides with the needle drop portion 21a, and the reduction in sewing efficiency can be suppressed. Especially in the case where the sewing machine 1 is an industrial sewing machine for sewing a large number of garments, it is advantageous.
在此，作為作業者將折回成兩層的布料設定在落針部21a的具體的一例，能夠列舉如按照服裝製造業者的指示來設定布料，該指示是關於以折回前的側縫部為基準使折回的布料的側縫部(腋縫部)位於一側或另一側的指示。 Here, as a specific example in which the operator sets the fabric folded back into two layers in the needle drop portion 21a, the cloth is set in accordance with an instruction from the clothing manufacturer, and the instruction is based on the side seam portion before the folding back. An indication that the side seam portion (quilted portion) of the folded fabric is located on one side or the other side.
凹部46的下端46a(參照圖6A)，在通過落針部21a的前後方向縱剖面中位於距針板21的上面H46(參照圖4)的位置。亦即，該凹部46的下端位在針板21的上面和縫紉機座2a的下端位置的上下方向距離，與距上方1/3的位置相比較位於下方，且與上述縫紉機座2a的下端相比較位於上方。本實施形態中，驅動引導部42的驅 動氣缸45位於縫紉機座2a的下部。但即使這樣，本實施形態中，在針板21的上面和縫紉機座2a的下端位置的上下方向距離H2a(參照圖4)中，能夠在凹部46確保距離H2a的1/3以上的距離H46量的高度尺寸，因此，在布料折回裝置4中至少能夠確保供作業者的手的一部分伸入的空間。此外，凹部46沒有必要形成能夠供作業者的手的五根手指全部伸入，形成一部分的手指能夠伸入即可。在該情況下，與不形成凹部46的情況比較，作業者能夠使手容易接近落針部21a。 The lower end 46a (see FIG. 6A) of the recessed portion 46 is located at a position from the upper surface H46 (see FIG. 4) of the needle plate 21 in the longitudinal section through the front-rear direction of the needle drop portion 21a. That is, the lower end of the recessed portion 46 is located in the up-and-down direction of the upper surface of the needle plate 21 and the lower end position of the sewing machine base 2a, and is located below the position of the upper third and is compared with the lower end of the sewing machine base 2a. Located above. In the present embodiment, the drive guide 42 is driven The moving cylinder 45 is located at a lower portion of the sewing machine base 2a. In the present embodiment, in the vertical direction distance H2a (see FIG. 4) of the upper surface of the needle plate 21 and the lower end position of the sewing machine base 2a, the distance H46 of the 1/3 or more of the distance H2a can be secured in the concave portion 46. Since the height of the height is small, at least the space in which the part of the operator's hand protrudes can be secured in the cloth folding back device 4. Further, it is not necessary for the recessed portion 46 to be formed so that all five fingers of the operator's hand can be formed, and a part of the fingers can be inserted. In this case, the operator can easily access the needle drop portion 21a with respect to the case where the concave portion 46 is not formed.
對於凹部46的下端46a，具體為考慮作業者的平均的手的尺寸，在通過落針部21a的前後方向縱剖面中，使其位於從針板21的上面向下方25mm~100mm的位置。藉著將凹部46的下端設定在該位置，對於大部分的作業者都能夠容易地將手伸入凹部46。 Specifically, in consideration of the average hand size of the operator, the lower end 46a of the recessed portion 46 is located at a position 25 mm to 100 mm downward from the upper surface of the needle plate 21 in the longitudinal cross section of the needle drop portion 21a. By setting the lower end of the recess 46 at this position, most of the operators can easily reach into the recess 46.
此外，如圖6B、圖6C所示，在凹部46具有傾斜部462的情況下，希望作為凹部的下端46a的傾斜部462的下端462a是位於落針部21a的前後方向縱剖面中，在針板21的上面和縫紉機座2a的下端位置的上下方向距離H2a(參照圖4)中，與距上部1/3的位置相比較位於下方，且與上述縫紉機座2a的下端相比較位於上方。 Further, as shown in FIG. 6B and FIG. 6C, in the case where the concave portion 46 has the inclined portion 462, it is desirable that the lower end 462a of the inclined portion 462 as the lower end 46a of the concave portion is located in the longitudinal section of the needle drop portion 21a in the front-rear direction, in the needle The vertical distance H2a (see FIG. 4) of the upper surface of the plate 21 and the lower end position of the sewing machine base 2a is located below the position of the upper 1/3, and is located above the lower end of the sewing machine base 2a.
以上，說明了本發明的實施形態，但本發明不限於上述各實施形態，在不脫離本發明主旨的範圍內能夠追加各種變更。 The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiments, and various modifications can be added without departing from the spirit and scope of the invention.
例如，凹部46除了形成在布料折回裝置4上，還能夠形成在縫紉機座2a上。另外，本實施形態的縫紉機具有尤其適用於“管狀物”的布料的構成，但並非“管狀物”縫製專用，當然也能夠用來縫製平坦的布料。因此，縫紉機座2a除了如本實施形態的“筒式”以外，還可以是“平座”。另外，本實施形態的縫紉機1為多針雙鏈線跡縫紉機，但在其他種類縫紉方式的縫紉機中，也能夠在布料折回裝置4上形成凹部46。 For example, the recess 46 can be formed on the sewing machine base 2a in addition to the cloth folding back device 4. Further, the sewing machine of the present embodiment has a configuration of a cloth which is particularly suitable for a "tubular article". However, it is not intended to be used for sewing a "tubular article", and it is of course also possible to sew a flat cloth. Therefore, the sewing machine base 2a may be a "seat" as in the "cylinder type" of the present embodiment. Further, the sewing machine 1 of the present embodiment is a multi-needle double-chain stitch sewing machine. However, in the sewing machine of another type of sewing type, the concave portion 46 can be formed in the cloth folding back device 4.
