Description

Technical Field

[0001] This invention relates to the field of inner patch bag processing technology, and in particular to a method for using a one-time sewing template for inner patch bags. Background Technology

[0002] The sewing of inner patch pockets typically involves the positioning, alignment, and continuous stitching of multiple fabric pieces, making it a crucial step in garment and bag production. Currently, the mainstream inner patch pocket sewing methods in the industry still have many shortcomings, hindering improvements in production efficiency and product quality. On the one hand, the traditional sewing method adopts the "multiple positioning-segment sewing-manual adjustment" mode, which requires first fixing and sewing the first piece of fabric, then taking it out, adjusting and positioning the second piece of fabric, and so on to complete the sewing of multiple pieces of fabric. The connection between the processes is cumbersome, and the pieces of fabric need to be repeatedly disassembled and assembled in the middle. This not only results in a long sewing time for a single inner patch bag and low production efficiency, but also easily causes cumulative errors due to multiple positioning, affecting the alignment accuracy of the pieces of fabric.

[0003] On the other hand, existing sewing methods are highly dependent on manual operation. The positioning, pressing, and avoidance of the cut pieces rely heavily on the experience and skills of the operators. Different operators have different operating techniques, which can easily lead to quality problems such as sewing thread deviation and loose fit of the cut pieces. At the same time, it is difficult to accurately control the connection rhythm of each process during manual operation, which can easily lead to operational errors, further increasing the rework rate and production costs.

[0004] Furthermore, existing sewing methods lack standardized processes, resulting in high learning costs. New operators require extensive training to master key techniques such as pattern positioning and sewing avoidance, leading to long training cycles and low production efficiency for businesses. At the same time, traditional methods are poorly compatible with automated equipment, making it difficult to integrate into existing industrialized mass production systems and fully leverage the automation advantages of automatic template machines, thus hindering the upgrading of the industry's production model.

[0005] Furthermore, the existing sewing methods and template structures lack sufficient synergy. Traditional methods do not fully integrate the standardized process of template structural function design, and the positioning and avoidance structures of the template cannot be effectively utilized. The irrationality of the methods further limits the performance of the template, resulting in a disconnect between "structure and method" and making it difficult to achieve simultaneous improvement in sewing efficiency and quality.

[0006] Therefore, a method for using a one-time sewing template for inner patch bags is proposed, which solves the problem of multiple positioning and repeated disassembly and assembly in the traditional sewing of inner patch bags, and shortens the sewing time for a single set of inner patch bags. Summary of the Invention

[0007] The purpose of this invention is to provide a method for using a one-time sewing template for inner patch bags, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A method for using a one-time sewing template for inner patch bags involves employing a template composed of a fixed base plate, a fixed partition plate, a sliding plate clamping plate, and left and right sliding plate covers, sequentially bonded together. This template, used in conjunction with an automatic template machine, enables the one-time forming of the inner patch bag. The template incorporates an outer sliding plate assembly, an inner sliding plate flipping assembly, and a side sliding tensioning assembly. The method includes the following steps: S1: Align the first cut piece with the cut piece guide line on the bottom plate of the fixed plate and place it into the cut piece groove of the fixed plate partition. Flip the inward pressing plate body and press the first cut piece with the magnet. S2: Flip the right slide cover to open the right slide body, put the second piece into the cutting auxiliary groove of the right slide bottom plate, and close the cover to fix the second piece; S3: Flip the inner flap to cover the first piece and the inner flap pressing plate, put the third piece into the gap between the inner flap and the inner slide plate, slide the left slide plate so that the left slide plate groove is aligned with the second groove of the bottom plate, and cover and fix the third piece. S4: Fix the template to the automatic template machine through the slot, and move the template to the bottom of the sewing machine; S5: The sewing machine sews the first and third pieces of fabric through the left sliding plate groove, then removes the left sliding plate. S6: The moving mechanism drives the slider to slide along the side slide rail, and flips the inner flap through the elastic band, sewing the area between the inner slide plate and the fishbone spike inside the flap. S7: The sliding plate inside the sliding flip panel leaves a gap, which drives the right sliding plate to slide so that the first groove of the right sliding plate cover plate is aligned with the first groove of the bottom plate, and the second piece is sewn and fixed. S8: Move the right slide plate so that the second groove of the right slide plate cover plate aligns with the third groove of the bottom plate, and sew along the two grooves to complete the full circumference sewing of the inner patch bag.

[0009] Preferably, in step S1, the cutting piece groove is opened around the cutting piece auxiliary line, and the inward-folding pressure plate is rotatably installed in the pressure groove formed by the partition plate pressure groove, the clamping plate pressure groove, and the cover plate pressure groove. The first cutting piece is accurately pressed and positioned by the magnet in the magnet hole of the inward-folding pressure plate and the magnet in the magnet hole of the bottom plate.

[0010] Preferably, in step S2, the right slide cover plate is hinged to the right slide bottom plate, the cutting auxiliary groove corresponds to the position of the cutting piece auxiliary line, and after the right slide cover plate is closed, the second cutting piece is confined in the cutting auxiliary groove to ensure that the positioning does not shift.

[0011] Preferably, in step S3, the inner flap is rotatably installed in the middle section inside the cutting piece groove, the inner slide plate of the flap is installed in the inner flap through the inner slide groove of the flap, and the left slide plate slides along the left slide groove so that the left slide groove is precisely aligned with the second groove of the bottom plate, and the third cutting piece is fixed by the covering effect.

[0012] Preferably, in step S4, the slots are simultaneously opened on the same side of the base plate of the fixed plate, the partition plate of the fixed plate, the slide plate clamping plate, and the left and right slide plate covers. The template is detachably fixed to the automatic template machine through the slots to ensure stable movement of the template during the sewing process.

[0013] Preferably, in step S5, after the left sliding plate groove is aligned with the second groove of the bottom plate to form a sewing channel, the left sliding plate body slides in the opposite direction along the left sliding plate groove to get out of the sewing range, so as to avoid interference with the sewing machine operation.

[0014] Preferably, in step S6, the slider is slidably installed in the side sliding track of the left and right slide cover plates. One end of the elastic band is fixed to the slider and the other end is fixed to the inner flip plate. The inner flip plate is flipped by sliding the slider, so that the area between the slide plate and the fishbone inside the flip plate is exposed.

[0015] Preferably, in step S7, the inner slide plate of the flip-up plate slides inward along the inner slide groove of the flip-up plate through the moving mechanism in cooperation with the second heightening fixing plate and the third push plate through hole, leaving a gap to avoid the right slide plate body. The right slide plate body slides along the right slide plate slide groove to ensure that the first groove of the right slide plate cover is aligned with the first groove of the bottom plate.

[0016] Preferably, in step S8, after the second groove of the right slide cover plate is aligned with the third groove of the bottom plate to form an annular sewing channel, the sewing machine sews along the first groove, the second groove of the right slide cover plate and the corresponding groove of the bottom plate to achieve full circumferential sewing of the second piece and the first piece.

[0017] Preferably, the left and right sliding plates of the outer sliding plate assembly slide along the corresponding sliding grooves, the inner flip plate and inner flip pressure plate of the inner sliding plate flipping plate assembly can be flipped, and the side sliding tensioning assembly drives the inner flip plate to flip through the slider and elastic band. The three work together to achieve the sequential positioning and continuous sewing of the first, second and third cut pieces, ensuring that the inner patch bag is formed in one go.

[0018] The beneficial effects of this invention are as follows: This invention, through a process design of "sequential positioning of cut pieces - segmented sewing - coordinated avoidance of components," achieves continuous sewing of the first, second, and third cut pieces without the need to remove cut pieces for adjustment or flipping during the process. This solves the problems of multiple positioning and repeated disassembly / reassembly in traditional inner patch bag sewing, significantly reducing the sewing time for a single set of inner patch bags and improving production efficiency. Each step in the method is precisely adapted to the template structure. For example, magnetic adsorption achieves cut piece clamping, sliding plate achieves sewing avoidance, and groove alignment ensures precise stitching. This avoids positioning errors and stitch deviations that occur in manual operation, resulting in neat stitches and tight fit of the cut pieces in the inner patch bag, reducing rework rates.

[0019] The entire process can be driven by an automatic template machine. Through the cooperation of the moving mechanism and the template slider, push plate through hole, elastic band and other structures, the automatic control of actions such as piece fixing, component movement and flip plate flipping is realized, reducing manual intervention, reducing the skill requirements of operators, and avoiding human error in manual operation. This invention breaks down the sewing of inner patch bags into 8 standardized steps. The steps are logically connected and the operation is clear. With the structural constraints of the template, such as corresponding slots and magnetic adsorption prompts, operators can quickly master the operation essentials, shorten the training cycle, and facilitate enterprises to start production quickly.

[0037] The method for making this inner label bag is as follows: The first, second, and third cut pieces are fixed on the template. The template is moved by an automatic template machine, and the first, second, and third cut pieces are sewn together by a sewing machine to complete the sewing of the inner patch pocket.

[0038] S1: Fix the first piece of cutting. Align the first piece of cutting along the piece of cutting auxiliary line 1011 and place it in the piece of cutting groove 1022. Flip the inward pressing plate 302. The inward pressing plate magnet 3021 attracts the magnet in the bottom plate magnet hole 1015, so that the inward pressing plate 302 presses the first piece of cutting. S2: Fix the second piece by flipping the right slide cover plate 2026 to open the right slide cover plate 202, place the second piece in the cutting auxiliary groove 2023, and close the right slide cover plate 2026 to fix the second piece. S3: Fix the third piece of fabric to flip the inner flap 301 so that it covers the first piece of fabric and the inner flap pressing plate 302. Place the third piece of fabric in the gap between the inner flap 301 and the inner slide plate 3013 of the flap. Slide the left slide plate 201 so that the left slide plate through groove 2011 is aligned with the second groove 1013 of the bottom plate to cover and fix the third piece of fabric. S4: Template and Equipment Fixation: The template is fixed to the automatic template machine via slot 6, and the automatic template machine moves the template to the bottom of the sewing machine. S5: The sewing machine sews the first and third pieces of fabric by using the left slide groove 2011 to fix one side of the first and third pieces of fabric; the left slide plate 201 is moved away by the moving mechanism to remove it from the working range; S6: The moving mechanism between the inner slide plate and the fishbone spike 3022 of the sewing flip plate drives the slider 4012 to slide along the side slide rail 1042, and drives the inner flip plate 301 to flip through the elastic band 4013. The sewing machine sews the area between the inner slide plate 3013 and the fishbone spike 3022 of the flip plate. S7: The second piece of fabric is sewn together with the other pieces of fabric by means of a moving mechanism, which is used to raise the fixing plate 2 3016 and the push plate through hole 3 3017, so that the inner slide plate 3013 of the flip plate slides inward to leave a gap; then, with the help of the push plate through hole 2025, the right slide plate 202 slides to the top of the piece of fabric, so that the first groove 2027 of the right slide plate cover is aligned with the first groove 1012 of the bottom plate, and the sewing machine sews through the groove to fix the second piece of fabric with the other pieces of fabric; S8: The inner patch bag sewing moving mechanism drives the right slide plate 202 to move, so that the second groove 2028 of the right slide plate cover is aligned with the third groove 1014 of the bottom plate; the sewing machine sews along the first groove 2027 and the second groove 2028 of the right slide plate cover, sewing the second piece around the first piece, and completing the inner patch bag production.

[0039] Working principle: The first cut piece is aligned with the cut piece guide line 1011 and placed inside the cut piece groove 1022. The inward flipping pressure plate 302 is flipped over, and the magnet in the magnet hole 3021 of the inward flipping pressure plate attracts the magnet in the magnet hole 1015 of the bottom plate, so that the inward flipping pressure plate 302 presses down on the first cut piece. The right slide cover plate 2026 is flipped over to open the right slide cover plate 202, and the second cut piece is placed inside the cutting guide groove 2023. The right slide cover plate 2026 is then closed to fix the second cut piece. The inward flipping plate 301 is flipped over to cover the first cut piece and the inward flipping pressure plate 302. The third cut piece is placed in the gap between the inward flipping plate 301 and the inner slide plate 3013 of the flipping plate. The left slide plate 201 is slid to align the left slide plate through groove 2011 with the second groove 1013 of the bottom plate, so that it covers the third cut piece, thereby completing the fixing of the cut piece.

[0040] The template is fixed to the automatic template machine via slot 6. The automatic template machine moves the template to the sewing machine. The sewing machine first sews through the left slide groove 2011 to fix one side of the first and third cut pieces. The moving mechanism moves the left slide plate 201 away from the working area. Then, the moving mechanism makes the slider 4012 slide, and the elastic band 4013 drives the inner flip plate 301 to flip, sewing between the inner slide plate 3013 and the fishbone spike 3022. Then, the moving mechanism, through the heightening fixing plate 3016 and the push plate through hole 3017, makes the inner slide plate 3013 slide inward, leaving a gap. The right slide plate 202 is slid above the cut piece by the moving mechanism in conjunction with the push plate through hole 2025, so that the first groove 2027 of the right slide plate cover is aligned with the first groove 1012 of the bottom plate. The first groove 2027 of the right slide plate cover is sewn to fix the second cut piece with the other two cut pieces. Then, the right slide plate 202 is moved by the moving mechanism so that the second groove 2028 of the right slide plate cover is aligned with the third groove 1014 of the bottom plate. The sewing machine sews along the first groove 2027 and the second groove 2028 of the right slide plate cover, so that the second cut piece is sewn to the first cut piece around it, thereby realizing the sewing of the inner patch bag.
