Description

  The present invention relates to a binder used in a sewing machine applied to the manufacture of a cotton garment and a sewing machine including the binder.

  In Japan, cotton garments that have been worn for cold protection have been used in the past, but their sales volume has been gradually increasing in recent years because of their high heat retention and excellent convenience and functionality. In order to produce a cotton garment half-wrap, for example, after lining up the outer fabric and lining tailored to the required shape and sewing them together at the hem part, the shape according to the front body, back body and sleeve part The cut and molded cotton is inserted between the outer material and the outer material, and the whole is inverted in that state. And the outer material and the lining material were sewn in the opening edge part containing a collar, and a sleeve edge part.

  However, since the sewing work at the opening edge and the sleeve edge is performed manually, the work efficiency is low, and the number of cotton linings that can be sewn per unit time is limited. Therefore, Patent Document 1 described later discloses the following sewing machine that sews the above-described open edge portion.

  That is, the above-mentioned opening edge is spanned between the outer surface and the lining of the opening edge, and the bag is bound by a long edge band disposed in the longitudinal direction of the opening edge. ing. In the sewing machine, a flat cylindrical binder called a canopy wrapper is erected on a base supporting the sewing machine portion so that the bottom thereof is substantially flush with the upper surface of the base. By inserting the edge band, both edges of the edge band are folded inward and the whole is folded in half, and in that state, the open edge is covered as described above, The lining and the other edge of the margin band were sewn together.

  FIG. 1 is a perspective view showing a sewing machine according to the present invention, in which 2 is a sewing machine portion. The sewing machine portion 2 includes an inverted L-shaped main body 21, and a base end portion 21 a of the main body 21 is fixed at an appropriate position on the flat plate-like base 1. A needle bar 23 is suspended from the tip 21b of the main body 21 so as to be able to advance and retract in the vertical direction, and a needle 24 is detachably attached to the lower end of the needle bar 23. The tip 21b is provided with a plurality of threading parts for guiding the upper thread, and the upper thread guided by each threading part passes through a balance that moves up and down in synchronization with the needle bar 23. It is supplied to the tip of a needle 24 attached to the lower end of the rod 23. In addition, a tone adjusting unit 25 is interposed in the middle position between the threading portions, and the tone adjusting unit 25 adjusts the tone of the upper thread wound around the tone adjusting unit 25. On the other hand, a lower thread and a hook (both not shown) are embedded in a region facing the needle bar 23 of the base 1, and the lower thread is inserted into the upper thread loop sewn by the needle. It is supposed to let you. Further, the sewing machine portion 2 is driven by a pressing portion 26 for pressing the sewing material, a feeding portion (not shown) for moving the sewing material forward and backward, and the needle bar 23, the balance, the feeding portion, and the like described above. A drive unit and the like are provided.

  An edge band (see the edge band FT shown in FIG. 5) for sewing the edge of the material to be sewn such as cotton-filled clothes is folded in front of the sewing machine part 2 of the base 1 as will be described later. The binder 3 for standing up is substantially parallel to the sewing machine portion 2, and the binder 3 folds both edges of the edge band supplied from one side inward and folds the whole in two. While folding, the other side of the needle bar 23 of the sewing machine portion 2 is led out to a position slightly ahead of the position where the needle bar 23 moves up and down.

  The binder 3 is provided with a fixing flange portion 35 for fixing the binder 3 to the base 1. The fixing flange portion 35 has a long hole extending from one side of the binder 3 in the same direction as the other side. 36 are established. The binder 3 is fixed to the base 1 by screws 37, 37 that pass through the long holes 36. By loosening the screws 37, 37, the binder 3 is moved in the axial direction of the long axis of the long holes 36. To get.

  On the other hand, a holder portion 7 that holds a wound edge band is attached to a corner portion of the base 1, and an edge drawn from the holder portion 7 is provided between the holder portion 7 and the binder 3. A guide 8 for guiding the belt to the binder 3 is provided.

  FIG. 2 is a rear perspective view of the binder 3 shown in FIG. 1, and FIG. 3 is a plan perspective view of the binder 3 shown in FIG. 4 is a cross-sectional view taken along line IV-IV of the binder 3 shown in FIG. The configuration of the binder 3 will be described in detail with reference to FIGS. 2 to 4 and FIG.

  As shown in FIGS. 1 to 4, the binder 3 includes an insertion portion 31 for inserting the edge band pulled out from the holder portion 7, and the edge band inserted into the insertion portion 31 is folded into a predetermined shape and led out. A folding portion 32 that lifts the material to be sewn from the base 1 and guides the pedestal portion 33 that guides the material to be sewn into the gap where the edge band led out from the folding portion 32 is folded. I have.

  The insertion portion 31 described above is configured such that the middle plate 30a and the back plate 30b are opposed to each other with a dimension slightly larger than the thickness of the edge band, and an insertion port 31a having the same width as the edge band is formed in the vertical direction. ing. Both side portions of the intermediate plate 30a are raised so as to gradually increase as the distance from the insertion port 31a increases, and accordingly, the width of the back plate 30b gradually decreases as the distance from the insertion port 31a increases. As a result, the edge band inserted into the insertion portion 31 is gradually raised to an appropriate height on both sides, and is introduced into the folding portion 32.

  The folding part 32 includes a back plate 30 b continuous from the insertion part 31. An appropriate gap is provided between both side portions of the region portion of the folding portion 32 of the back plate 30b and both side portions of the region portion of the insertion portion 31 of the back plate 30b, and an edge band is provided in the binder 3. When setting, both side portions of the edge band can be easily pulled out from the insertion portion 31 and into the folding portion 32. Both side portions of the region portion of the folding portion 32 of the back plate 30b are raised to the same height as the portion of the insertion portion 31 on the folding portion 32 side, and are further folded to the opposite sides to form the first folding portions 32a and 32a. Therefore, both side portions of the edge band are folded in half while passing through the first folding portions 32a and 32a.

  In addition, the region portion of the folding portion 32 of the back plate 30b is protruded to the front side so that the center of the folding plate 32 becomes a substantially inverted isosceles triangle wedge shape when viewed from the back, and thereby the width dimension is separated from the insertion portion 31. It becomes narrower gradually. On the other hand, on the front side of the folding portion 32, a folding middle plate 30c having a substantially isosceles triangle shape in a front view is disposed with an appropriate gap from the back plate 30b, thereby the second folding portion 32b. Is formed. The height dimension of the folding intermediate plate 30c is gradually increased as the distance from the insertion portion 31 increases, so that the portion in the vicinity of the outlet 32c from which the edge band of the folding intermediate plate 30c is led out has a roll U shape. There is no. Further, the region portion of the folding portion 32 of the back plate 30b is also formed in a rollover U shape corresponding to the shape of the portion in the vicinity of the outlet port 32c of the folding middle plate 30c, whereby the inside of the second folding portion 32b. The edge band introduced to is folded in half at a substantially central position in the width direction and led out from the outlet 32c.

  An edge band led out from the lead-out port 32c is supplied to the lead-out port 32c of the folding part 32 and an edge portion of the material to be sewn is inserted. A covering portion 34 for covering the supplied edge band is fitted inside the edge portion. The covering portion 34 is substantially U-shaped when viewed from the front, and has an appropriate length dimension from the front side to the back side.

  In the vicinity of the covering portion 34, width adjusting pieces 38, 38 for adjusting the width of the edge band to be sewn on the material to be sewn are protruded slightly from both side edges of the covering portion 34. The width dimension of the edge band to be sewn on the material to be sewn can be adjusted by adjusting the dimension which is fixed by screws and protrudes from both side edges of the covering portion 34 of the width adjusting pieces 38, 38. ing. The edge band introduced into the fold-in part 32 is folded in two at both sides, and is folded in half at the center in the width direction, and is led out from the outlet 32c. Since both edge portions of the edge band are in contact with the width adjusting pieces 38, 38, the width is adjusted to a required width.

  A guiding pedestal 33 for guiding the material to be sewn to the covering 34 is disposed adjacent to the covering 34. The guiding pedestal portion 33 is formed by a thin plate-like flat portion 33a placed on the upper surface of the base 1 (see FIG. 1) and the flat portion 33a, and is formed from the flat portion 33a. A first slope portion 33b that is gradually increased to a high required height position, and is formed continuously from the first slope portion 33b toward the covering portion 34 from the height position of the first slope portion 33b. The second slope portion 33c is gradually lowered. The second inclined surface portion 33c is disposed on the front side of the folding portion 32 described above over at least the region in the length direction of the covering portion 34. Moreover, the 1st slope part 33b and the flat part 33a are extended in the side on the opposite side to the said insertion part 31 side of the 2nd slope part 33c, and the to-be-sewn material on the base 1 is for induction | guidance | derivation. The base portion 33 is slid on the flat portion 33a, the first slope portion 33b, and the second slope portion 33c in this order to be guided into the covering portion 34.

  In the guiding pedestal portion 33 shown in the present embodiment, the first inclined surface portion 33b and the second inclined surface portion 33c described above are flush with each other, whereby the first inclined surface portion 33b and the second inclined surface portion 33c. One slope portion formed of the portion 33c is formed. In the longitudinal direction of the folding portion 32 of the binder 3, the slope portion gradually increases as it approaches the lead-out port 32c from a position separated from the lead-out port 32c to the side opposite to the insertion portion 31 side, In a direction orthogonal to the longitudinal direction of the folding part 32, a slope gradually lowering from the front side of the binder 3 toward the back side of the binder 3 is formed. In this way, by forming one slope portion consisting of the first slope portion 33b and the second slope portion 33c, the first slope portion 33b and the second slope portion 33c are guided compared to the case where each is formed separately. The manufacturing cost of the pedestal portion 33 can be further reduced.

  Needless to say, the first slope portion 33b and the second slope portion 33c may be formed separately without being flush with each other.

  FIGS. 6 and 7 are external perspective views showing a semi-wrapped cotton as a material to be sewn. FIG. 6 shows a state before sewing by the sewing machine shown in FIG. 1, and FIG. Each state of sewing is shown.

  As shown in FIG. 6, the semi-finished H with cotton is provided with a surface material SF and a lining material BF which are cut and sewed into a required shape, and the surface material SF and the lining material BF are overlapped in an inverted state. After the two parts are sewn together, a cotton member C cut and molded into a shape corresponding to the front body, back body and sleeve is inserted between the outer surface SF and the lining BF, and the whole is inverted in that state. It is. And before sewing with a sewing machine, the open edge part HF containing a heel is released, and the cotton member C appears between the surface material SF and the lining material BF.

  And as shown in FIG. 7, the open part of the said open edge part HF is bordered by spanning the both sides of the elongate edge band FT ranging from the surface material SF of this open edge part HF to the lining BF. Cover with FT, and in that state, one side edge of the edge band FT, the outer surface SF, the lining BF, and the other side edge of the edge band FT are sewn together. The surrounding of the opening part of the open edge part HF by such an edge band FT, and the sewing of the other side edge part of the edge band FT, the outer surface SF, the lining BF, and the edge band FT are as follows. Done.

  FIG. 5 is an explanatory view for explaining a state in which the open edge portion HF of the semi-finished cotton-filled H is sewn by the sewing machine shown in FIG. In the figure, parts corresponding to those shown in FIG.

  As shown in FIG. 5, the wound edge band FT is held in the holder part 7, and the edge band FT drawn out from the holder part 7 is inserted into the insertion opening of the binder 3 via the guide part 8. It is inserted into the insertion part 31 from 31a. The edge band FT is led out from the outlet after being folded in four at the first folding parts 32a and 32a and the second folding part 32b of the folding part 32 as described above. However, the edge band FT is turned upside down. As described above, the front view is introduced into the covering portion along the inner surface of the U-shaped covering portion. A portion of the open edge HF of the semi-finished cotton H is introduced from the guide pedestal 33 into the covering portion, whereby the edge band FT extends from the outer surface SF to the lining BF of the open edge HF. Both sides are stretched.

  The needle bar 23 and the needle 24 constituting the sewing machine part 2 are arranged at a position on the back side of the sewing machine part 2 at an appropriate distance from the covering part, and the cotton-filled semi-wrap H derived from the covering part H The opening edge portion HF and the edge band FT of the edge band FT are sewn together by the needle 24 at one side edge of the edge band FT, the outer surface SF, the backing BF, and the other edge of the edge band FT.

  At this time, since the flat portion 33a of the guide base portion 33 is formed in a thin plate shape, and almost no step is formed between the flat portion 33a and the base 1, the semi-summary H containing cotton is placed on the base 1. The sliding edge HF of the semi-finished cotton H is transferred from the base 1 onto the guiding base 33 via the flat portion 33a.

  As shown in FIGS. 2 and 3, the guide base 33 shown in the present embodiment is substantially rectangular in plan view, and the flat portion 33a is inserted from the outlet 32c into the insertion portion. It is provided on the corner located on the back surface side of the binder 3 so as to have a triangular shape when separated from the side opposite to the 31 side. Thereby, the corner | angular part which comprises the flat part 33a can enter under the cotton semi-finished H reliably, and the open edge part HF of the cotton semi-finished H is reliably transferred on the flat part 33a.

  The opening edge HF is slid on the first slope portion 33b of the guide base portion 33 and lifted to an appropriate high position. As a result, an appropriate gap is generated between the base 1 and the cotton blank H, so that the operator can easily grasp the front and back of the sewn portion of the open edge HF. Therefore, the efficiency of sewing work by the sewing machine portion 2 is improved. In addition, the front and back of the sewing portion of the open edge portion HF can be reliably gripped, and the occurrence of wrinkles at the sewing portion can be easily avoided.

  On the other hand, as described above, the open edge portion HF that has been slid on the first slope portion 33b and lifted to an appropriate high position is slid onto the second slope portion 33c of the guide base portion 33, and 2. It is guided into the covering portion disposed at a relatively low position by the inclined surface portion 33c. Thereby, the open edge part HF of the half wrapping H containing cotton can be reliably guided into the covering part.

  By the way, the above-described covering portion is attached in a posture such that the inner surface 34a (see FIGS. 2 and 3) on the lower side of the roll U shape is flush with the second inclined surface portion 33c. Accordingly, no step is generated between the covering portion and the second inclined surface portion 33c, so that the open edge portion HF of the cotton-filled semi-summary H is smoothly guided from the second inclined surface portion 33c into the covering portion. Further, the open edge portion HF of the cotton-filled semi-summary H guided to the appropriate height position by the first slope portion 33b is in a state where the level difference is eliminated as much as possible by the second slope portion 33c and the covering portion. It will be moved on the base 1, and it is prevented that wrinkles generate | occur | produce in the open edge part HF and the edge band FT.

  On the other hand, the dimension between the rolling U-shaped inner side surfaces 34a, 34a (see FIGS. 2 and 3) of the covering portion is set to be slightly larger than the thickness dimension of the open edge portion HF of the cotton-wrapped half-wrap H. It is. As a result, the opening edge HF and the edge band FT covering the opening edge HF can be slid at the same speed without being displaced from each other, so that the edge band FT is prevented from wrinkling.
