Description

  The present invention relates to a method for manufacturing a comforter in which a plurality of cloth portions are overlapped and the contents are accommodated in an internal space formed between the plurality of cloth portions.

  Utility Model Registration No. 3002931 discloses a rectangular upper front fabric positioned on the upper side, a rectangular lower front fabric positioned on the lower side, and an internal space between the upper front fabric and the lower front fabric. A skin blanket with filled batting is described. The upper front fabric and the lower front fabric are formed with a plurality of straight stitches extending in the vertical and horizontal directions, and filling is filled in each of the internal spaces partitioned by the straight stitch portions. The interval between the directly stitched portions is set to a few tens of centimeters, which is smaller than a general comforter. In this skin blanket, the upper outer fabric and the lower outer fabric are sewed together and the inner space is filled with the filling of synthetic fiber, and then the upper and lower outer fabrics are directly sewn vertically and horizontally. It is manufactured by.

Utility Model Registration No. 3002931

  As described above, the skin blanket is manufactured by stitching the peripheral edges and filling the inner space with fillings, and then performing direct stitching vertically and horizontally. In this way, if the direct stitching is performed after the contents are stored in the internal space, the seam may meander. Here, as described above, when the straight stitch portion is formed in the vertical and horizontal directions after the contents are accommodated, there is a concern that the design of the comforter may be impaired due to an increase in the number of seams that can meander.

  Further, when the interval between the direct stitch portions is relatively wide, even if the seam meanders as described above, it is relatively difficult to cause a problem. However, when the interval between the direct stitch portions is narrowed, the distance of the entire seam is increased, and there is a concern that the number of seam portions that can meander further increases. Therefore, the design of the comforter is impaired, and the uniformity of the content of the comforter may be reduced.

  An object of this invention is to provide the manufacturing method of the comforter which can improve the designability of a comforter and can suppress the fall of the uniformity of a content, even when the space | interval of a direct stitching part is narrowed.

  The comforter manufacturing method according to one aspect of the present invention includes a first cloth portion extending in a second direction intersecting the first direction and the first direction, and a first direction and a second direction superimposed on the first cloth portion. A plurality of first straight stitching portions extending in the first direction and containing contents in an internal space formed between the first fabric portion and the second fabric portion. A method for manufacturing a comforter in which a plurality of second directly-sewn portions extending in a second direction are formed, wherein the first fabric portion is overlapped with the outer edge of the first fabric portion in a state where the first fabric portion is superimposed on the second fabric portion. A step of stitching a portion of the outer edge of the two cloth portions other than a portion into which an injector for injecting contents enters, and a plurality of first straight stitching portions at least from one outer edge extending in the second direction toward the other outer edge Steps to be formed up to the middle part and inserting the injector into the internal space, a plurality of first straight stitching parts Therefore, the step of injecting the contents into each of the partitioned internal spaces, the step of removing the injectors from the internal spaces and sealing the places where the injectors enter, and the contents so as to be uniform in the internal spaces And a step of forming a plurality of second straight stitch portions between one outer edge extending in the first direction and the other outer edge.

  In this comforter manufacturing method, after the plurality of first straight stitching portions extending in the first direction are formed from one outer edge extending in the second direction to at least the middle portion toward the other outer edge, the contents are accommodated. ing. Therefore, the distance of the direct stitching part formed after accommodation of the contents can be shortened as compared with the case where the direct stitching part is formed vertically and horizontally after the contents are accommodated. Therefore, by forming the first straight stitches before accommodating the contents, it is possible to reduce the number of seams that can meander, and thus it is possible to suppress a decrease in design of the comforter. In addition, the contents are accommodated after the first straight stitching portion is formed first, and even if the interval between the first straight stitching portions is narrowed, the number of seams that can meander is not increased. While suppressing a fall, the fall of the uniformity of a content can also be suppressed. Furthermore, in this comforter, the interval between the first straight stitched portions can be narrowed to increase the number of first straight stitched portions that are linear, thereby improving the design and the uniformity of the contents. Can do. In addition, since the number of seams that can meander can be reduced, the number of comforters that are defective can be reduced, so that loss of the comforter material can be suppressed. And since direct stitching can be efficiently performed by reducing the number of seams that can meander, workability in the production of comforters can be improved.

  Further, in the step of stitching together the parts other than the part into which the injector for injecting the contents enters the outer edge of the first cloth part and the outer edge of the second cloth part, one place where the injector enters is formed at a plurality of positions. In the step of forming one straight stitch portion, the first straight stitch portion is formed from one outer edge extending in the second direction to the middle portion toward the other outer edge, and the injector is inserted into the inner space. After injecting a thing, you may form a some 1st direct stitch part from the middle part to the other outer edge. In this case, since the location where the injector enters is one location, the location where the injector enters after the contents are accommodated can be easily sealed. Therefore, the workability of the comforter manufacturing can be improved. Moreover, even if the first straight stitching portion is narrow and plural, the number of locations to be sealed can be reduced, which contributes to further improvement in work efficiency.

  Moreover, you may seal the location where an injection device penetrates before forming a some 1st direct stitch part between an intermediate part and the other outer edge. In this case, after the contents are accommodated by the injector and before the first straight stitching portion is completely formed, the portion where the injector enters is sealed, so that the first and second cloth portions are sealed at an early stage. The outer edge of the part can be completely sealed. Therefore, it is possible to prevent the contents from leaking from the comforter at an earlier stage.

  According to the present invention, even when the interval between the straight stitch portions is narrowed, the design of the comforter can be improved and the uniformity of the contents can be prevented from being lowered.

It is a perspective view which shows the comforter of this embodiment. It is a top view which shows typically the comforter of FIG. (A) is the IIIA sectional view taken on the line of FIG. (B) is the IIIB-IIIB sectional view taken on the line of FIG. (A), (b) and (c) is a figure which shows the manufacturing process of the comforter of FIG. (A), (b) and (c) is a figure which shows the continuation of the manufacturing process of FIG.

  Hereinafter, embodiments of a method for manufacturing a comforter according to the present invention will be described with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 1, the comforter 1 according to the present embodiment has a rectangular shape as a whole. The comforter 1 is, for example, a skin comforter that is thinner than a normal comforter (thin comforter), and can be used in summer or attached to the main comforter (as an additional sheet) in winter. . The outer shape of the comforter 1 is formed by a rectangular first cloth portion 2 and a rectangular second cloth portion 3 located on the back side of the first cloth portion 2. The first cloth part 2 and the second cloth part 3 have the same shape and size, for example.

  As shown in FIGS. 2 and 3, the first cloth portion 2 and the second cloth portion 3 are in the form of a flat cloth extending in a first direction D <b> 1 that is the short direction and in a second direction D <b> 2 that is the longitudinal direction. It has become. Here, the first direction D1 is orthogonal to the second direction D2, for example. As materials for the first fabric portion 2 and the second fabric portion 3, various materials such as cotton, cotton blend, polyester, or rayon can be used.

  The first fabric portion 2 has an outer edge 2A including two short sides 2a and two long sides 2b, and the second fabric portion 3 similarly has an outer edge 3A including short sides 3a and long sides 3b. . By combining the short side 2a of the first cloth part 2 and the short side 3a of the second cloth part 3, the long side 2b of the first cloth part 2 and the long side 3b of the second cloth part 3 are combined, The outer edge 2A of the first cloth part 2 and the outer edge 3A of the second cloth part 3 are overlapped. And the 1st cloth part 2 and the 2nd cloth part 3 are connected by sewing the outer edge 2A of the 1st cloth part 2, and the outer edge 3A of the 2nd cloth part 3 in this state.

  Furthermore, the comforter 1 partitions the internal space S formed by the first cloth portion 2 and the second cloth portion 3 and partitions the internal space S with a plurality of first straight stitch portions 4 extending in the first direction D1. A plurality of second straight stitching parts 5 extending in two directions D2. That is, the comforter 1 has a first straight stitching portion 4 that is a straight quilt (European quilt) extending in the first direction D1 and a second straight stitching portion 5 that is a straight quilt extending in the second direction D2.

  Here, the term “direct stitched portion” used in this specification indicates a portion where direct stitching has been performed, and more specifically, the first fabric portion 2 and the second fabric portion 3 are directly connected. The part which was sewn and the solid quilt is not interposed between the first cloth part 2 and the second cloth part 3 is shown.

  The first straight stitching portion 4 is formed by performing direct stitching in the first direction D1 from the first cloth portion 2 or the second cloth portion 3 with a sewing machine or the like, and the second straight stitching portion 5 is similarly secondly sewn with a sewing machine or the like. It is formed by performing direct sewing in the direction D2. In the first straight stitch portion 4, the first fabric portion 2 and the second fabric portion 3 are sewn by sewing the thread 4 a directly into the first and second fabric portions 2 and 3. In the second straight stitch portion 5, the thread 5 a is directly sewn into the first fabric portion 2 and the second fabric portion 3. Various materials such as cotton, cotton blend, polyester, or rayon can be used as the material of the thread 4a constituting the first straight stitch portion 4 and the material of the thread 5a constituting the second straight stitch portion 5. is there.

  For example, 27 first straight stitches 4 are provided, four second straight stitches 5 are provided, and 27 first straight stitches 4 and four second straight stitches 5 are: The first cloth part 2 and the second cloth part 3 are orthogonal to each other. In a general comforter, the number of first straight stitches 4 is about 4 to 6, but in the comforter 1 of the present embodiment, the number of first straight stitches 4 is made larger than that of a general comforter. The design of the comforter 1 and the uniformity of the contents are improved.

  Further, for example, the 27 first straight stitch portions 4 are arranged so as to be equally spaced from each other, and the four second straight stitch portions 5 are also arranged so as to be equally spaced from each other. The number of the first straight stitch portions 4 is larger than the number of the second straight stitch portions 5, and the interval between the first straight stitch portions 4 is narrower than the interval between the second straight stitch portions 5. For example, the interval between the first straight stitch portions 4 is 8 cm, and the interval between the second straight stitch portions 5 is 30 cm.

  The comforter 1 is partitioned by the first straight stitching portion 4 and the second straight stitching portion 5 so that the number of internal spaces S is 140 (28 × 5). The contents 6 are accommodated in each. 2, 4, and 5, the contents 6 accommodated in the internal space S are shown in gray. As the contents 6, for example, various materials such as feathers (feathers), polyester (synthetic fibers), or cotton can be used.

  Next, the manufacturing method which manufactures the comforter 1 is demonstrated, referring FIG.4 and FIG.5.

  First, as shown in FIG. 4A, the first cloth portion 2 is overlapped with the second cloth portion 3. Specifically, the first cloth part 2 is covered with the second cloth part 3, the short side 2 a of the first cloth part 2, the short side 3 a of the second cloth part 3, and the long side of the first cloth part 2. 2b and the long side 3b of the second cloth portion 3 are aligned. Then, the portions other than the portion P where the injector 7 for injecting the contents 6 enters in the outer edge 2A of the first cloth portion 2 and the outer edge 3A of the second cloth portion 3 are sewn together (the injector 7 for injecting the contents 6). The process of sewing together the parts other than the part P where the thread enters).

  Here, the injector 7 has, for example, a cylindrical shape, and the contents 6 are injected into the inner space S of the comforter 1 by jetting the contents 6 from the injector 7. Moreover, the location P into which the injector 7 enters is formed at one location. Specifically, the place P into which the injector 7 enters is, for example, a hole formed at one end (right end) of one short side 2a, 3a (upper short sides 2a, 3a), and the injector 7 is inserted. The size is possible.

  As described above, after the outer edges 2A and 3A are sewn other than the portion P where the injector 7 enters, as shown in FIG. 4B, the plurality of first straight stitch portions 4 are moved in the second direction D2. Between one outer edge 2A, 3A (one long side 2b, 3b) extending to the other outer edge 2A, 3A (the other long side 2b, 3b).

  At this time, a plurality of first straight stitch portions 4 are formed between one long side 2b and 3b and a middle portion W toward the other long side 2b and 3b. The interval between the plurality of first straight stitch portions 4 is large enough to allow at least the tip of the injector 7 to enter. Further, the distance between the intermediate portion W and the other long sides 2b and 3b is such that at least the tip of the injector 7 can be freely moved to some extent within the interior where the first fabric portion 2 and the second fabric portion 3 are stitched together. For example, it is 10 cm.

  Next, as shown in FIG. 4C, the injector 7 is inserted into the internal space S, and the contents 6 are injected into each of the internal spaces S partitioned by the plurality of first straight stitch portions 4. Specifically, the injector 7 is inserted into the internal space S from the point P, and the injector 7 is inserted between the intermediate portion W and the long sides 2b and 3b. And the injection port of the injector 7 is inserted in each area | region S1 of the internal space S partitioned off by the some 1st direct stitch part 4, and the content 6 is injected from the injector 7 to the back of area | region S1. As a result, the content 6 is pushed into the back side of the region S1 of the internal space S.

  After injecting the contents 6 into each region S1 of the internal space S in this way, as shown in FIG. 5 (a), the injector 7 is removed from the location P, and the location P into which the injector 7 is inserted is changed. Seal. By this sealing, measures are taken to prevent leakage of the contents 6 from the location P. Specifically, the location P may be directly sewn and sealed, or the location P may be temporarily stopped by a clip or the like and the location P may be sewn in a later process. However, in the case where the portion P is sewn at this stage, the leakage of the contents 6 from the first cloth portion 2 and the second cloth portion 3 can be prevented at an early stage, and there is an advantage that the subsequent work can be performed smoothly. .

  Subsequently, as shown in FIG. 5B, a plurality of first straight stitch portions 4 are formed between the intermediate portion W and the other outer edges 2A and 3A (the other long sides 2b and 3b). To do. In this way, 27 first straight stitch portions 4 are completed.

  Then, as shown in FIG. 5C, a step of leveling the contents 6 so as to be uniform in the internal space S is performed. At this time, for example, by moving the contents 6 in the first direction D1 while pushing the first cloth part 2 or the second cloth part 3 in the first direction D1 by hand, the state of the contents 6 in the internal space S is changed. Make uniform. Thereafter, as shown in FIG. 2, from one outer edge 2A, 3A (for example, the upper short side 2a, 3a) extending in the first direction D1 to the other outer edge 2A, 3A (for example, the lower short side 2a, 3a) ), The comforter 1 is completed.

  As described above, in the method of manufacturing the comforter 1 of the present embodiment, the plurality of first straight stitches 4 extending in the first direction D1 are extended from one outer edge 2A, 3A extending in the second direction D2 to the outer edge 2A, the other end. The contents 6 are accommodated after being formed at least up to the middle part W toward 3A. Therefore, the distance of the direct stitching part formed after accommodation of the content 6 can be shortened compared with the case where a straight stitching part is formed in the length and breadth after accommodation of the content 6. In the present embodiment, the distance of the straight stitch portion formed after the contents 6 are accommodated is the distance from the midway portion W to the other outer edge 2A, 3A and the distance of the four second straight stitch portions 5. Can do.

  Here, when the straight stitch portion is formed after the contents 6 are accommodated, the seam can meander, but in the present embodiment, by forming the first straight stitch portion 4 before the contents 6 are accommodated, the seam that can meander is formed. Can be reduced. Therefore, it is possible to suppress a decrease in design properties of the comforter 1. Further, since the contents 6 are accommodated after the first straight stitch portion 4 is formed first, even if the interval between the first straight stitch portions 4 is narrowed, the number of seams that can meander is not increased. Accordingly, it is possible to suppress a decrease in the design properties of the comforter 1 and to suppress a decrease in the uniformity of the contents 6. Furthermore, in this comforter 1, the interval between the first straight stitching portions 4 can be narrowed to increase the number of first straight stitching portions 4 that are linear, thereby enabling the design and uniformity of the contents 6. Can be improved. Here, if the seam meanders directly after the contents are stored as in the conventional case, this comforter may be treated as a defective product. In this case, each process until the comforter is manufactured is wasted. Become. However, in the present embodiment, as described above, since the first straight stitch portion 4 is formed before the contents 6 are accommodated, the possibility that the comforter is treated as a defective product can be reduced. The process can be made efficient.

  Further, in the step of sewing the portions other than the portion P where the injector 7 for injecting the contents 6 enters the outer edge 2A of the first fabric portion 2 and the outer edge 3A of the second fabric portion 3, the portion P where the injector 7 enters. Is formed in one place. In the step of forming the plurality of first straight stitch portions 4, the first straight stitch portion 4 is extended from one outer edge 2A, 3A extending in the second direction D2 to the middle portion W toward the other outer edge 2A, 3A. After the injection device 7 is inserted into the internal space S and the contents 6 are injected, a plurality of first straight stitch portions 4 are formed between the intermediate portion W and the other outer edges 2A, 3A. ing. Therefore, since the place P into which the injector 7 enters is one place, the place P into which the injector 7 enters after the contents 6 are accommodated can be easily sealed. Therefore, workability of manufacturing the comforter 1 can be improved.

  Moreover, in the manufacturing method of the comforter 1 according to the above-described embodiment, the place where the injector 7 enters before the plurality of first straight stitch portions 4 are formed between the intermediate portion W and the other outer edges 2A, 3A. P is sealed. Therefore, since the portion P is sealed after the contents 6 are received by the injector 7 and before the first straight stitch portion 4 is completely formed, the first cloth portion 2 can be sealed at an early stage. And the outer edges 2A and 3A of the 2nd cloth part 3 can be sealed completely. Therefore, it is possible to prevent the contents 6 from leaking from the comforter 1 at an earlier stage.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, You may deform | transform in the range which does not change the summary described in the claim. That is, the present invention can be variously modified without departing from the gist described in the claims.

  For example, in the above-described embodiment, an example in which one place P into which the injector 7 enters is formed has been described. However, two or more places P into which the injector 7 enters may be formed. In the above-described embodiment, the example in which the place P into which the injector 7 enters is formed at one end of the short sides 2a and 3a has been described. However, the place of the place P can be changed as appropriate.

  In the above-described embodiment, the plurality of first straight stitch portions 4 are formed between the one outer edge 2A, 3A extending in the second direction D2 and the middle portion W toward the other outer edge 2A, 3A. At this time, it is also possible to form a plurality of first straight stitch portions 4 between one outer edge 2A, 3A extending in the second direction D2 and the other outer edge 2A, 3A.

  Moreover, in above-mentioned embodiment, the location P in which the injection device 7 enters immediately after accommodating the contents 6 is sealed, and then the first straight stitching portion between the middle portion W and the other long sides 2b and 3b. 4 was formed. However, immediately after the contents 6 are accommodated, the first straight stitching portion 4 is formed between the intermediate portion W and the long sides 2b and 3b on the other side, and the portion P into which the injector 7 enters thereafter is sealed. May be.

  In the above-described embodiment, the example in which the 27 first straight stitch portions 4 and the four second straight stitch portions 5 are provided has been described. However, the first straight stitch portion 4 and the second straight stitch portion 5 are provided. This number is not limited to the above and can be changed as appropriate. Further, the interval between the first straight stitch portions 4 and the interval between the second straight stitch portions 5 can be changed as appropriate. That is, the 1st direct stitching part and the 2nd direct stitching part do not need to be arrange | positioned at equal intervals. Moreover, in the above-described embodiment, the example in which the first straight stitching portion 4 and the second straight stitching portion 5 are both linear has been described. However, the first straight stitching portion and the second straight stitching portion may be curved.

  In the above-described embodiment, the example in which the first direction D1 and the second direction D2 are orthogonal to each other has been described. However, the directions D1 and D2 do not have to be orthogonal to each other and do not cross each other. That's fine.
