Description

Technical Field

[0001] The invention relates to the technical field of clothing manufacturing, and in particular to a three-dimensional down-filling compartment sewing tool and a sewing method. Background Art

[0002] In the production process of down clothing, in order to ensure the warmth retention and comfort of the clothing, multiple filling compartments are sewn on the clothing, and the down is evenly filled into the filling compartments. When sewing the filling compartments, two layers of fabric are often used to form a filling space, and then the filling space is divided into multiple filling compartments that are continuously arranged along the height direction of the clothing to ensure the stability of the down in each filling compartment and avoid the problem of down aggregation. However, when the user wears the above-mentioned clothing, the user's movements will cause the fabric to deform or move, and the fabric will exert a pulling force on the filling compartment along the height direction of the clothing, causing the structure of the filling compartment to become flatter, thereby reducing the fluffiness of the filling compartment and affecting the warmth retention effect of the clothing.

[0003] In order to solve the above problems, some existing down garments form multi-layer filling chambers between two layers of fabric by folding. The filling chambers formed in this way are three-dimensional structures, and the multiple filling chambers are independent of each other, so that when the garment is worn, the three-dimensional filling chamber will not become flat under the traction of the fabric, ensuring the fluffiness of the down in the filling chamber and improving the warmth effect of the garment. However, in the process of sewing the three-dimensional filling chamber, the staff needs to draw the position to be folded on the fabric before sewing, and fold the fabric continuously while ensuring that the edges of the two layers of fabric are always aligned, which makes the sewing process of the filling chamber more complicated and reduces the efficiency of garment production; and due to the influence of manual operation, the accuracy of the folding position of the fabric each time cannot be guaranteed, which affects the quality of garment production; in addition, the sewing of the three-dimensional filling chamber also has high requirements on the sewing technology of the staff, which increases the cost of garment production.

[0004] Therefore, there is an urgent need for a three-dimensional down filling bin sewing tool and a sewing method to solve the above problems. Summary of the invention

[0048] Embodiment 1

[0049] like Figures 1 to 5 As shown, this embodiment provides a three-dimensional filling bin sewing tool, which can improve the efficiency of sewing the three-dimensional filling bin 1021, reduce the requirements on the sewing level of the staff and the cost of producing down clothing, and can also accurately control the size of the three-dimensional filling bin 1021, thereby ensuring the production quality of down clothing.

[0050] See also Figure 1 The down garment comprises a down filling layer 100, the down filling layer 100 comprises a plane portion 101 and a folding portion 102 connected to each other, the plane portion 101 is arranged along a first direction ( Figure 1 The folded portion 102 is located in the plane portion 101 along its thickness direction ( Figure 1 On one side of the folding portion 102 (in the Z direction), a three-dimensional filling chamber 1021 is provided in the folding portion 102. Figure 1 , Figure 2 and Figure 3 The three-dimensional down filling warehouse sewing tool comprises a bottom plate 1, a cover plate 2 and a positioning plate 3, and the down filling layer 100 can be positioned and laid on the bottom plate 1; the cover plate 2 is rotatably connected to the bottom plate 1, and the cover plate 2 has a sewing position stacked with the bottom plate 1 and an adjustment position arranged at an angle with the bottom plate 1, and a plurality of first sewing holes 21 extending along a first direction are provided on the cover plate 2; the positioning plate 3 can be detachably arranged on the bottom plate 1, and when in the sewing position, the positioning plate 3 is connected to the bottom plate 1 and clamped between the cover plate 2 and the bottom plate 1, and the first edge 31 of the positioning plate 3 can be aligned with any first sewing hole 21, and the down filling layer 100 can be folded along the second edge 32 of the positioning plate 3, and the first edge 31 and the second edge 32 are respectively the first edge 32 and the second edge 32 of the positioning plate 3 along the second direction ( Figure 2 On both sides of the Y direction), the first direction and the second direction are perpendicular to the thickness direction of the planar portion 101.

[0051] The three-dimensional down filling bin sewing tool provided in the present embodiment is arranged at an angle with the base plate 1 when adjusting the position, so that the positioning plate 3 can be separated from the base plate 1, which is convenient for the staff to adjust the position of the down filling layer 100 on the base plate 1; when the cover plate 2 is rotated to the sewing position, the positioning plate 3 is clamped between the base plate 1 and the cover plate 2, so that the down filling layer 100 can be clamped by the cover plate 2 and the base plate 1, effectively preventing the down filling layer 100 from moving during the sewing process, thereby affecting the sewing effect of the down filling layer 100. When adjusting the position, connect the positioning plate 3 to the base plate 1, and ensure that the first edge 31 of the positioning plate 3 can be aligned with any first sewing hole 21, ensure that the sewing equipment can pass through the corresponding first sewing hole 21 and sew the down filling layer 100 clamped between the base plate 1 and the cover plate 2, wherein the setting of the first sewing hole 21 can avoid the cover plate 2 affecting the sewing of the down filling layer 100 when the sewing position is adjusted; the staff folds the down filling layer 100 along the second edge 32 of the positioning plate 3 at the adjusted position, so that the down filling layer 100 forms two overlapping layers at the positioning plate 3, so that when the sewing equipment sews along the first edge 31, the above-mentioned two overlapping layers of down filling layers 100 can be sewn together along the first direction to form a folded portion 102, completing the sewing of the three-dimensional filling compartment 1021, and ensuring the warmth of the down clothing. Compared with the prior art, the process of sewing the three-dimensional filling bin 1021 using the three-dimensional filling bin sewing tooling provided in this embodiment does not require the staff to manually determine the folding position of the down filling layer 100, and also ensures the folding accuracy of the down filling layer 100, which can not only improve the efficiency of sewing the three-dimensional filling bin 1021, but also reduce the requirements on the sewing level of the staff, which helps to reduce the production cost of down clothing; moreover, the folding of the down filling layer 100 about the positioning plate 3 can ensure that the sizes of all the folded parts 102 sewn are the same, and thus the staff no longer needs to perform powder painting before sewing, which reduces the occurrence of contamination of the down filling layer 100 and ensures the production quality of down clothing.

[0052] For example, see Figure 1 and Figure 2 The first direction is the width direction of the down filling layer 100 of the bottom plate 1 , and the second direction is the length direction of the down filling layer 100 of the bottom plate 1 .

[0053] For example, see Figure 1 and Figure 3 The bottom plate 1, the cover plate 2 and the positioning plate 3 are all made of transparent plastic such as PVC, so that the staff can observe the position and folding condition of the down filling layer 100 through the cover plate 2 when sewing.

[0054] Optionally, see Figure 1 , Figure 2 and 5The three-dimensional down filling chamber sewing tool also includes a pressing plate 4, which is detachably connected or rotatably connected to the bottom plate 1. When the cover plate 2 switches from the adjustment position to the sewing position, the pressing plate 4 is stacked with the bottom plate 1. The pressing plate 4 can partially press the down filling layer 100 against the bottom plate 1, thereby preventing the down filling layer 100 from moving on the bottom plate 1, so as to ensure the accuracy of the position of the down filling layer 100 on the bottom plate 1 during the sewing process, and ensure the quality of the finished down clothing. When adjusting the position, the staff can provide space for the laying of the down filling layer 100 on the bottom plate 1 by rotating the pressing plate 4 or separating the pressing plate 4 from the bottom plate 1, so as to prevent the pressing plate 4 from affecting the laying of the down filling layer 100.

[0055] Specifically, see Figure 1 and Figure 5 , the down filling layer 100 is folded along the second direction, and the pressing plate 4 extends along the first direction to prevent the pressing plate 4 from affecting the folding of the down filling layer 100 .

[0056] In this embodiment, the pressing plate 4 is rotatably connected to the bottom plate 1. Exemplarily, the three-dimensional stuffing chamber sewing tool further includes a first adhesive strip, one side of the first adhesive strip is bonded to the bottom plate 1, and the other side is bonded to the pressing plate 4. Since the first adhesive strip can be deformed, when the pressing plate 4 rotates, the pressing plate 4 can drive the first adhesive strip and the side bonded to it to rotate relative to the other side of the first adhesive strip, thereby realizing the rotatable connection between the pressing plate 4 and the bottom plate 1.

[0057] Exemplarily, the first adhesive strip is an adhesive tape.

[0058] In other embodiments, the pressing plate 4 is detachably connected to the bottom plate 1. For example, a plug connector is provided on the bottom plate 1, and a socket is provided on the pressing plate 4. When the plug connector is plugged into the socket, the bottom plate 1 is connected to the pressing plate 4, and when the plug connector is detached from the socket, the bottom plate 1 is separated from the pressing plate 4.

[0059] Exemplarily, the connector is a hook.

[0060] In an alternative embodiment, see Figure 1 , Figure 3 and Figure 4, a plurality of first positioning members 11 are arranged on the bottom plate 1, and the plurality of first positioning members 11 correspond to the plurality of first sewing holes 21 one by one. A positioning hole 33 is arranged on the positioning plate 3, and the first positioning member 11 can be inserted into the positioning hole 33 or detached from the positioning hole 33. When the first positioning member 11 is inserted into the positioning hole 33, the position of the positioning plate 3 on the bottom plate 1 can be limited to ensure that the positioning plate 3 does not move during the sewing process, thereby ensuring the production quality of the down filling layer 100; when the first positioning member 11 detaches from the positioning hole 33, the positioning plate 3 can be separated from the bottom plate 1, so that the positioning plate 3 can be moved to align with other first sewing holes 21 to sew other folding parts 102. The first positioning member 11 is connected to the positioning plate 3 by plugging, so that the positioning plate 3 can be quickly connected to the bottom plate 1, and it is convenient for the staff to quickly determine the position where the positioning plate 3 is connected to the bottom plate 1, so as to ensure that the first side 31 of the positioning plate 3 can be aligned with the first sewing hole 21.

[0061] Exemplarily, the first positioning member 11 is a magnetic buckle or a hook.

[0062] Further, see Figure 4 and Figure 5 A first positioning piece 11 is provided at both ends of the bottom plate 1 along the first direction, and a positioning hole 33 is provided at both ends of the positioning plate 3 along the first direction to ensure the stability when the positioning plate 3 is connected to the bottom plate 1, and to prevent the two ends of the positioning plate 3 from moving relative to each other along the first direction, thereby affecting the sewing accuracy.

[0063] In another alternative embodiment, see Figure 1 , Figure 2 and Figure 5 , a plurality of second positioning members 12 are arranged on the bottom plate 1, and the plurality of second positioning members 12 correspond to the plurality of first sewing holes 21 one by one, and the second positioning members 12 extend along the first direction, and the second edge 32 of the positioning plate 3 can contact any second positioning member 12 to limit the position of the positioning plate 3 on the bottom plate 1, prevent the positioning plate 3 from moving during the sewing process, and ensure the production quality of the down filling layer 100. The provision of the second positioning members 12 not only enables the positioning plate 3 to be quickly connected to the bottom plate 1, but also facilitates the staff to quickly determine the position where the positioning plate 3 is connected to the bottom plate 1, so as to ensure that the first edge 31 of the positioning plate 3 can be aligned with the first sewing hole 21.

[0064] Exemplarily, the second positioning member 12 is a strip-shaped patch.

[0065] In another alternative embodiment, see Figure 1 and Figure 2The base plate 1 is provided with both a first positioning member 11 and a second positioning member 12, which significantly improves the efficiency of positioning the positioning plate 3 on the base plate 1 and the stability after the positioning plate 3 is connected to the base plate 1, and further ensures the finished product quality of the down filling layer 100.

[0066] Optionally, see Figure 1 and Figure 2 The down filling layer 100 includes two stacked layers of fabric, and a plurality of second sewing holes 22 are provided on the cover plate 2. The plurality of second sewing holes 22 are arranged at intervals along the circumference of the down filling layer 100. When in the sewing position, the sewing device can pass through the plurality of second sewing holes 22 and sew the two layers of fabric. The provision of the second sewing holes 22 can prevent the cover plate 2 from affecting the connection of the two layers of fabric by the sewing device when in the sewing position. With such a provision, the three-dimensional down filling bin sewing tool provided in this embodiment can also sew the two layers of fabric together before sewing the folding portion 102, so as to ensure that the two layers of fabric will not move relative to each other during the subsequent sewing process, thereby ensuring the quality of the sewing of the down filling layer 100; it also expands the operable procedures of sewing the down filling layer 100 by the three-dimensional down filling bin sewing tool provided in this embodiment, thereby improving the versatility of the three-dimensional down filling bin sewing tool.

[0067] Optionally, see Figure 1 and Figure 2 The down filling layer 100 includes a plurality of folding portions 102 and a plurality of plane portions 101. The plurality of folding portions 102 correspond to the plurality of plane portions 101 one by one. A plurality of first sewing holes 21 are provided. The plurality of first sewing holes 21 are arranged at intervals along the second direction, and the distance between any two adjacent first sewing holes 21 is the same as the length of the plane portion 101 along the second direction. With such an arrangement, after the sewing equipment sews along any two adjacent first sewing holes 21, a plane portion 101 is formed between two sewing lines while the folding portion 102 is formed, which reduces the process flow of the production of the down filling layer 100 and improves the production efficiency of the down filling layer 100.

[0068] In this embodiment, multiple first positioning members 11 and multiple second positioning members 12 are provided, and the multiple first positioning members 11 and multiple second positioning members 12 correspond one-to-one to the multiple first sewing holes 21 to ensure that the positioning plate 3 can be quickly placed at any first sewing hole 21.

[0069] Further, see Figure 5 A plurality of positioning plates 3 are provided, so that a plurality of folding portions 102 can be sewn simultaneously each time, further improving the production efficiency of the down filling layer 100 .

[0070] Exemplarily, two positioning plates 3 are provided, and the plurality of first sewing holes 21 are symmetrically arranged about the midline of the cover plate 2 along the first direction. The pressing plate 4 is located in the middle of the bottom plate 1 along the second direction. Each time sewing is performed, the two positioning plates 3 are located on both sides of the pressing plate 4 along the second direction. Figure 5 In the orientation, on the left side of the pressing plate 4, the left side of the positioning plate 3 is the second side 32, and the right side of the positioning plate 3 is the first side 31; on the right side of the pressing plate 4, the right side of the positioning plate 3 is the second side 32, and the left side of the positioning plate 3 is the first side 31.

[0071] Optionally, the three-dimensional filling chamber sewing tool further includes a second adhesive strip extending along a second direction, one side of the second adhesive strip is bonded to the base plate 1 , and the other side is bonded to the cover plate 2 to achieve a rotational connection between the base plate 1 and the cover plate 2 .

[0072] Specifically, the second adhesive strip can be deformed. When the cover plate 2 rotates, the cover plate 2 can drive the second adhesive strip to rotate with one side thereof bonded thereto relative to the other side of the second adhesive strip, thereby achieving a rotational connection between the cover plate 2 and the base plate 1 .

[0073] Exemplarily, the second adhesive strip is made of adhesive tape.

[0074] Optionally, see Figure 1 and Figure 2 , a positioning line 13 is drawn on the bottom plate 1, and the positioning line 13 extends along the outer contour of the down filling layer 100. When the down filling layer 100 is laid on the bottom plate 1, the position of the down filling layer 100 is adjusted so that the outer contour of the down filling layer 100 is aligned with the positioning line 13, so that the accuracy of the placement of the down filling layer 100 on the bottom plate 1 can be ensured.
