Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garment manufacturing, and in particular to a three-dimensional down-filled pocket sewing tool and sewing method. BACKGROUND

[0002] In the production process of down clothing, in order to ensure the warmth and comfort of the clothing, multiple down-filled pockets are sewn on the clothing, and down is evenly filled into the down-filled pockets. When sewing the down-filled pockets, first, a down-filled space is formed by using two layers of fabric, and then the down-filled space is divided into multiple down-filled pockets arranged continuously along the height direction of the clothing, so as to ensure the stability of the down in each down-filled pocket and avoid the problem of down aggregation. However, during the wearing of the above-mentioned clothing by the user, the user's movements will cause the fabric to deform or move, and the fabric will generate a pulling force along the height direction of the clothing on the down-filled pocket, causing the structure of the down-filled pocket to become relatively flat, thereby reducing the loft of the down-filled pocket and affecting the warmth of the clothing.

[0003] To solve the above-mentioned problems, some existing down clothing forms multiple down-filled pockets between two layers of fabric by folding. The down-filled pockets formed in this way have a spatial three-dimensional structure, and multiple down-filled pockets are independent of each other, so that during the wearing of the clothing, the three-dimensional down-filled pocket will not become flat under the action of the pulling force of the fabric, ensuring the loft of the down in the down-filled pocket and improving the warmth of the clothing. However, during the sewing of the three-dimensional down-filled pocket, the worker needs to draw the position to be folded on the fabric before the sewing operation, and constantly folds the fabric while ensuring that the edges of the two layers of fabric are always aligned, making the sewing process of the down-filled pocket relatively complicated and reducing the efficiency of clothing production. Moreover, due to the influence of manual operation, the accuracy of the folding position of the fabric cannot be guaranteed, affecting the quality of clothing production. In addition, the sewing of the three-dimensional down-filled pocket also has high requirements for the sewing skills of the worker, increasing the cost of clothing production.

[0004] Therefore, there is an urgent need for a three-dimensional down-filled pocket sewing tool and sewing method to solve the above-mentioned problems. SUMMARY

[0005] The present application aims to provide a three-dimensional down-filled pocket sewing tool and sewing method that can improve the efficiency of sewing three-dimensional down-filled pockets, reduce the requirements for the sewing skills of the worker and the cost of down clothing production, and also accurately control the size of the three-dimensional down-filled pocket, ensuring the production quality of down clothing.

[0048] Embodiment one

[0049] As shown in Figures 1 to 5 , the present embodiment provides a three-dimensional down-filled pocket sewing tool, which can improve the efficiency of sewing the three-dimensional down-filled pocket 1021, reduce the requirement for the sewing level of the workers and the cost of down clothing production, and also can accurately control the size of the three-dimensional down-filled pocket 1021, thereby ensuring the production quality of the down clothing.

[0050] Referring to Figure 1 , the down clothing includes a down-filled layer 100, the down-filled layer 100 includes a planar part 101 and a folded part 102 connected to each other, the planar part 101 extends along a first direction (X direction in Figure 1 ), and the folded part 102 is located on one side of the planar part 101 along its thickness direction (Z direction in Figure 1 ), and the three-dimensional down-filled pocket 1021 is arranged in the folded part 102. Referring to Figure 1 , Figure 2 and Figure 3 , the three-dimensional down-filled pocket sewing tool includes a bottom plate 1, a cover plate 2 and a positioning plate 3, and the down-filled layer 100 can be positioned and laid on the bottom plate 1; the cover plate 2 is rotationally connected with the bottom plate 1, the cover plate 2 has a sewing position stacked with the bottom plate 1 and an adjusting position arranged at an angle with the bottom plate 1, and a plurality of first sewing holes 21 extending along the first direction are arranged on the cover plate 2; the positioning plate 3 is detachably arranged on the bottom plate 1, in the sewing position, the positioning plate 3 is connected with the bottom plate 1 and clamped between the cover plate 2 and the bottom plate 1, a first edge 31 of the positioning plate 3 can be aligned with any first sewing hole 21, and the down-filled layer 100 can be folded along a second edge 32 of the positioning plate 3, the first edge 31 and the second edge 32 are two edges of the positioning plate 3 along a second direction (Y direction in Figure 2 ), and the first direction and the second direction are perpendicular to the thickness direction of the planar part 101.

[0051] The three-dimensional down-filled bin sewing tool provided by the embodiment is characterized in that: the cover plate 2 is arranged at an angle with the bottom plate 1 when the position is adjusted, so that the positioning plate 3 can be separated from the bottom plate 1, thereby facilitating the staff to adjust the position of the down-filled layer 100 on the bottom plate 1; when the cover plate 2 is rotated to the sewing position, the positioning plate 3 is clamped between the bottom plate 1 and the cover plate 2, so that the down-filled layer 100 can be clamped by the cover plate 2 and the bottom plate 1, thereby effectively preventing the down-filled layer 100 from moving during sewing and affecting the sewing effect of the down-filled layer 100. When the position is adjusted, the positioning plate 3 is connected with the bottom plate 1, and the first edge 31 of the positioning plate 3 is ensured to be aligned with any first sewing hole 21, so that the sewing equipment can pass through the corresponding first sewing hole 21 and sew the down-filled layer 100 clamped between the bottom plate 1 and the cover plate 2, wherein the arrangement of the first sewing hole 21 can avoid the influence of the cover plate 2 on the sewing of the down-filled layer 100 when the position is adjusted; the staff folds the down-filled layer 100 along the second edge 32 of the positioning plate 3 when the position is adjusted, so that the down-filled layer 100 forms two layers overlapping each other at the positioning plate 3, thereby enabling the above-mentioned two layers of the down-filled layer 100 to be sewn together in the first direction when the sewing equipment sews along the first edge 31, so as to form a folded part 102, and the sewing of the three-dimensional down-filled bin 1021 is completed, thereby ensuring the warmth of the down garment. Compared with the prior art, the process of sewing the three-dimensional down-filled bin 1021 using the three-dimensional down-filled bin sewing tool provided by the embodiment not only does not require the staff to manually determine the folding position of the down-filled layer 100, but also ensures the folding accuracy of the down-filled layer 100, thereby not only improving the efficiency of sewing the three-dimensional down-filled bin 1021, but also reducing the requirement for the sewing level of the staff, which helps to reduce the production cost of the down garment; in addition, folding the down-filled layer 100 about the positioning plate 3 can ensure that the size of all the folded parts 102 sewn is the same, thereby eliminating the need for the staff to perform the powder drawing operation before sewing, reducing the occurrence of pollution of the down-filled layer 100, and ensuring the production quality of the down garment.

[0052] For example, referring to Figure 1 and Figure 2 , the first direction is the width direction of the down-filled layer 100 of the bottom plate 1, and the second direction is the length direction of the down-filled layer 100 of the bottom plate 1.

[0053] For example, referring to 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-filled layer 100 through the cover plate 2 when the position is adjusted.

[0054] Optionally, referring to Figure 1 , Figure 2 and 5The stereoscopic filling warehouse sewing tool further comprises a pressing plate 4, which is detachably connected or rotatably connected with the bottom plate 1. When the cover plate 2 is switched from the adjusting position to the sewing position, the pressing plate 4 is stacked with the bottom plate 1. The pressing plate 4 can press the part of the down filling layer 100 to the bottom plate 1, so as to avoid the movement of the down filling layer 100 on the bottom plate 1, to ensure the accuracy of the position of the down filling layer 100 on the bottom plate 1 during the sewing process, and to ensure the quality of the down clothing finished product. When the adjusting position is adjusted, the worker can provide space for laying the down filling layer 100 on the bottom plate 1 by rotating the pressing plate 4 or detaching the pressing plate 4 from the bottom plate 1, so as to avoid the influence of the pressing plate 4 on the laying of the down filling layer 100.

[0055] Specifically, referring to 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, so as to avoid the influence of the pressing plate 4 on the folding of the down filling layer 100.

[0056] In this embodiment, the pressing plate 4 is rotatably connected with the bottom plate 1. Exemplarily, the stereoscopic filling warehouse sewing tool further comprises a first adhesive strip, one side of the first adhesive strip is adhered with the bottom plate 1, and the other side of the first adhesive strip is adhered with 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 to rotate relative to the other side of the first adhesive strip, so as to realize the rotatable connection between the pressing plate 4 and the bottom plate 1.

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

[0058] In other embodiments, the pressing plate 4 is detachably connected with the bottom plate 1. Exemplarily, the bottom plate 1 is provided with a plug-in part, and the pressing plate 4 is provided with a plug hole. When the plug-in part is plugged into the plug hole, the bottom plate 1 is connected with the pressing plate 4. When the plug-in part is separated from the plug hole, the bottom plate 1 is separated from the pressing plate 4.

[0059] Exemplarily, the plug-in part is a hook.

[0060] In an optional embodiment, referring to Figure 1 , Figure 3 and Figure 4The bottom plate 1 is provided with a plurality of first positioning members 11, the plurality of first positioning members 11 correspond to the plurality of first sewing holes 21 one by one, the positioning plate 3 is provided with a positioning hole 33, and the first positioning member 11 can be inserted into or separated 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, so that the positioning plate 3 does not move during sewing, and the quality of the production of the down filling layer 100 is ensured; when the first positioning member 11 is separated 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 be aligned with other first sewing holes 21 to sew other folding parts 102. The first positioning member 11 is connected with the positioning plate 3 in a plug-in manner, so that the positioning plate 3 can be quickly connected with the bottom plate 1, and the position of the positioning plate 3 connected with the bottom plate 1 can be quickly determined by the worker, so as to ensure that the first edge 31 of the positioning plate 3 can be aligned with the first sewing hole 21.

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

[0062] Further, referring to Figure 4 and Figure 5 , the bottom plate 1 is provided with the first positioning member 11 at both ends in the first direction, and the positioning plate 3 is provided with the positioning hole 33 at both ends in the first direction, so as to ensure the stability of the positioning plate 3 connected with the bottom plate 1, prevent the relative movement of the positioning plate 3 at both ends in the first direction, and affect the precision of sewing.

[0063] In another optional embodiment, referring to Figure 1 , Figure 2 and Figure 5 , the bottom plate 1 is provided with a plurality of second positioning members 12, the plurality of second positioning members 12 correspond to the plurality of first sewing holes 21 one by one, the second positioning member 12 extends in the first direction, and the second edge 32 of the positioning plate 3 can be in contact with any second positioning member 12, so as to limit the position of the positioning plate 3 on the bottom plate 1, prevent the positioning plate 3 from moving during sewing, and ensure the quality of the production of the down filling layer 100. The second positioning member 12 not only enables the positioning plate 3 to be quickly connected with the bottom plate 1, but also enables the worker to quickly determine the position of the positioning plate 3 connected with 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 adopts a strip-shaped patch.

[0065] In another optional embodiment, referring to Figure 1 and Figure 2The first positioning member 11 and the second positioning member 12 are arranged on the bottom plate 1, which significantly improves the positioning efficiency of the positioning plate 3 on the bottom plate 1 and the stability of the connection between the positioning plate 3 and the bottom plate 1, and further guarantees the finished product quality of the down filling layer 100.

[0066] Optionally, referring to Figure 1 and Figure 2 , the down filling layer 100 includes two layers of fabrics stacked together, and the cover plate 2 is provided with a plurality of second sewing holes 22, which are arranged along the circumference of the down filling layer 100 at intervals. When sewing, the sewing equipment can pass through the plurality of second sewing holes 22 and sew the two layers of fabrics. The arrangement of the second sewing hole 22 can avoid the influence of the cover plate 2 on the connection of the two layers of fabrics by the sewing equipment during sewing. In this way, the three-dimensional down filling bin sewing tool provided in this embodiment can also sew the two layers of fabrics together before sewing the folding part 102, so as to ensure that the two layers of fabrics do not move relative to each other during the subsequent sewing process, thereby guaranteeing the quality of the down filling layer 100. The three-dimensional down filling bin sewing tool provided in this embodiment also expands the operable process of the three-dimensional down filling bin sewing tool for sewing the down filling layer 100, thereby improving the versatility of the three-dimensional down filling bin sewing tool.

[0067] Optionally, referring to Figure 1 and Figure 2 , the down filling layer 100 includes a plurality of folding parts 102 and a plurality of flat parts 101, the plurality of folding parts 102 correspond to the plurality of flat parts 101 one by one, the first sewing hole 21 is provided with a plurality of first sewing holes 21, 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 flat part 101 along the second direction. In this way, after the sewing equipment sews along any two adjacent first sewing holes 21, the flat part 101 is formed between the two sewing lines while the folding part 102 is formed, which reduces the process flow of the down filling layer 100 production and improves the efficiency of the down filling layer 100 production.

[0068] In this embodiment, the first positioning member 11 and the second positioning member 12 are both provided with a plurality of first positioning members 11 and a plurality of second positioning members 12, and the plurality of first positioning members 11 and the plurality of second positioning members 12 correspond to the plurality of first sewing holes 21 one by one, so as to ensure that the positioning plate 3 can be quickly placed at any first sewing hole 21.

[0069] Further, referring to Figure 5 , the positioning plate 3 is provided with a plurality of positioning plates 3, so that the sewing of a plurality of folding parts 102 can be performed at the same time each time, thereby further improving the efficiency of the down filling layer 100 production.

[0070] Exemplarily, the positioning plates 3 are provided with two first sewing holes 21, which are symmetrically arranged about the middle line of the cover plate 2 in the first direction, and the pressing plate 4 is located at the middle position of the bottom plate 1 in the second direction. During each sewing, the two positioning plates 3 are respectively located at the two sides of the pressing plate 4 in the second direction. Specifically, referring to the positions in Figure 5 , 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 down-filled pocket sewing tool further comprises a second adhesive strip extending in the second direction, one side of the second adhesive strip is bonded to the bottom plate 1, and the other side of the second adhesive strip is bonded to the cover plate 2, so as to realize the rotary connection of the bottom plate 1 and the cover plate 2.

[0072] Specifically, the second adhesive strip can be deformed, and when the cover plate 2 rotates, the cover plate 2 can drive the second adhesive strip to rotate relative to the other side of the second adhesive strip, thereby realizing the rotary connection of the cover plate 2 and the bottom plate 1.

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

[0074] Optionally, referring to Figure 1 and Figure 2 , the positioning line 13 is drawn on the bottom plate 1, and the positioning line 13 extends along the outer contour of the down-filled layer 100. When the down-filled layer 100 is laid on the bottom plate 1, the position of the down-filled layer 100 is adjusted so that the outer contour of the down-filled layer 100 is aligned with the positioning line 13, thereby ensuring the accuracy of the placement position of the down-filled layer 100 on the bottom plate 1.
