Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, and in particular to a template for sewing side pockets of trousers. Background Technology

[0002] The garment manufacturing industry is a typical labor-intensive industry, and the sewing process is a core link affecting product quality and production efficiency. During the sewing process, for complex parts that require multiple folds and alignments, such as the side pockets of trousers, the sewing quality is highly dependent on the skill and experience of the operators.

[0003] Currently, the sewing of side pockets on trousers is primarily done manually. Workers must hold the soft fabric and perform a series of operations on the sewing machine, including folding, aligning, and pushing, to ensure the seams are flat, the stitches are straight, and they conform to the design pattern. However, this traditional method has the following inherent drawbacks: Poor quality stability: Due to the soft, easily deformed, and slippery nature of the fabric, it is difficult to precisely control the folding angle, alignment, and the force and direction of the sewing push by hand. This easily leads to quality problems such as bent stitches, misaligned seams, and crooked stitches during the sewing process, resulting in a high defect rate and seriously affecting the consistency and aesthetics of the finished product.

[0004] High operational barriers and significant efficiency bottlenecks: Mastering precise sewing techniques requires long-term training and experience accumulation, resulting in lengthy and costly training cycles for novice sewing workers. Even among skilled workers, fatigue, concentration, and other human factors make it difficult to maintain a stable level of performance over extended periods, leading to large fluctuations in production efficiency and hindering the achievement of standardized, rhythmic assembly line production.

[0005] High cost control pressures: High defect rates mean increased waste of raw materials and rework costs. At the same time, the company's heavy reliance on skilled workers results in consistently high human resource management costs and training investments.

[0006] To address these issues, simple sewing templates have emerged in the industry, attempting to standardize the sewing path through guide grooves. However, for complex processes like trouser side pockets that require multiple steps, precise folding, and multi-layer alignment, existing simple templates offer limited functionality. They typically only solve the problem of "sewing straight lines" but cannot effectively guide and fix the fabric folding process, failing to fundamentally address the core challenges of folding accuracy and alignment precision. Operators still need to rely on experience for crucial alignment and folding operations, and quality risks remain uncontrolled. Utility Model Content

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] Example: like Figures 1 to 4 As shown, the present invention provides a trouser side pocket sewing template, which mainly consists of a lower hinge plate 1, an upper hinge plate 2, and an auxiliary flap disposed between the two.

[0022] The lower hinge plate 1 serves as the basic support plate. The material choices for the lower hinge plate include transparent or semi-transparent acrylic sheets, epoxy sheets, PET sheets, and PVC sheets. PVC sheets are typically chosen because they are reasonably priced. Using transparent or semi-transparent acrylic sheets makes it easier for the operator to observe the positioning of the underlying fabric. The upper surface of the lower hinge plate 1 is used to support the garment pieces for the side pockets of the trousers.

[0023] One side of the auxiliary flap is bonded to one edge of the lower hinge plate 1 and the upper hinge plate 2, so that the upper hinge plate 2 and the auxiliary flap can fold around the edge of the lower hinge plate 1, thereby covering or moving away from the lower hinge plate 1.

[0024] A first sewing groove 5 and a second sewing groove 6 are respectively opened on the upper hinge plate 2 and the lower hinge plate 1. The first sewing groove and the second sewing groove are used to guide the needle and thread path of the sewing machine. The first sewing groove is a longer straight groove when sewing the side pocket of the trousers, which is used to fix the slanted pocket opening. The second sewing groove is used to fix the upper pocket opening.

[0025] The upper end of the first sewing groove 5 intersects with one end of the second sewing groove 6. Below the intersection, and on the first sewing groove 5, a first knot sewing groove 10 is provided. The first knot sewing groove is usually rectangular or elliptical and is used to guide the sewing machine to perform thread reinforcement sewing (knotting) to prevent the groove from cracking or deforming after repeated use.

[0026] The auxiliary flap is positioned between the lower hinge plate 1 and the upper hinge plate 2 to precisely fix the folded garment pieces before sewing. In this embodiment, the auxiliary flap includes a first auxiliary plate 3 and a second auxiliary plate 4. The first auxiliary plate 3 is located above the lower hinge plate 1, and the second auxiliary plate 4 is located below the upper hinge plate 2. Several second auxiliary plates are provided, which can be designed according to usage needs. In this embodiment, two second auxiliary plates 4 are provided, corresponding to different folded parts of the pocket respectively. In use, the corresponding garment piece is first placed on the garment piece placement reference area 14 on the lower hinge plate, then the first auxiliary flap is pressed on the garment piece, clamping the garment piece tightly with the lower hinge plate. Then, other corresponding garment pieces are placed on the first auxiliary flap, and after positioning, the second auxiliary flap is pressed on the first auxiliary flap. The second auxiliary plate operation is repeated, and then the upper hinge plate is pressed on the corresponding second auxiliary flap. Each garment piece is pressed and positioned layer by layer, and then fixed before being placed in the sewing machine for sewing.

[0027] One side of the auxiliary flaps (first auxiliary plate 3 and second auxiliary plate 4) is bonded to the common side edge of the lower hinge plate 1 and the upper hinge plate 2, allowing them to fold independently. When the auxiliary flaps are placed on the lower hinge plate 1, the side of the auxiliary flaps away from the first sewing groove 5 and the second sewing groove 6 is parallel to the side edges of the lower hinge plate 1 and the upper hinge plate 2, and the other side of the auxiliary flaps forms a positioning edge 8. This positioning edge 8 is parallel to the first sewing groove 5, providing a precise physical reference for the folding line of the garment piece. When the auxiliary flaps are closed, they remain parallel to the first sewing groove at a fixed distance. The operator only needs to place the garment piece with the edge of the trouser piece close to this positioning edge to ensure that the garment piece is in the correct sewing position.

[0028] To further enhance the fixing effect and prevent the soft fabric from slipping during operation and affecting the stitching, the preferred implementation scheme is as follows: On one side of the positioning edge 8 of the second auxiliary plate 4, a fishbone spike 9 is provided along the positioning edge to prevent the fabric from springing back or shifting after folding.

[0029] A first auxiliary strip (not shown) is fixed on the upper surface of the lower hinge plate 1, close to the first sewing groove 3. Its direction is parallel to the first sewing groove 3. The first auxiliary strip is used for initial alignment when the garment piece is initially placed, so that the garment piece is aligned with the first sewing groove.

[0030] Furthermore, a second set of knotted sewing grooves 11 are also provided on the first sewing groove 5. The lower end of the first sewing groove 5 extends and passes through the second set of knotted sewing grooves 11. A third sewing groove 7 is provided below the first sewing groove 5. The direction of the third sewing groove 7 is different from that of the first sewing groove 3. The third sewing groove 7 passes through the first sewing groove 5 and the second set of knotted sewing grooves 11. The third sewing groove is used to fix the stitching of the lower pocket opening. The groove design of the third sewing groove can meet the more diverse sewing process requirements of the trouser side pockets, and the second set of knotted sewing grooves reinforce the stitching of the pocket.

[0031] Correspondingly, a second auxiliary strip (not shown) is provided on the upper surface of the lower hinge plate 1 on one side of the third sewing groove 7 to guide the fabric edge corresponding to the third sewing groove 7.

[0032] A third auxiliary strip (not shown) and a fourth auxiliary strip (not shown) are respectively provided on the lower surface of the upper hinge plate 2 and on both sides of the first sewing groove 3. The third and fourth auxiliary strips are parallel to the first sewing groove 5. When the upper hinge plate 2 is closed, these auxiliary strips can work in conjunction with the structure on the lower hinge plate 1 to firmly press the folded garment piece in place, forming a "fabric channel" to ensure that it does not move during the sewing process.

[0033] In this embodiment, the auxiliary strip serves to: (1) stabilize the position between the lower and upper hinge plates to ensure accurate placement of the garment pieces; (2) increase the height between the lower and upper hinge plates to accommodate the sewing groove for easy sewing by the sewing machine; and (3) ensure even stitching, preventing skewing or deformation, and resulting in fuller stitching. The auxiliary strip can be adhered to the corresponding position using adhesive. The auxiliary strip can be made of anti-slip cloth, silicone pads, sponge strips, etc.

[0034] On the positioning edge 8 of the auxiliary flap, a knotting auxiliary groove (not shown) corresponding to the positions of the first knotting groove 10 and the second knotting groove 11 can also be opened so that the knotting process can be completed even when the auxiliary flap is closed, increasing the flexibility of operation.

[0035] In this invention, a machine slot 15 is provided on the lower hinge plate near the folding end, so that the modified sewing template can be used with an automated sewing machine. In use, the machine slot on the sewing template is connected to the robotic arm on the sewing machine, the template drawing is input into the program, the garment pieces to be processed are placed, the sewing machine is started, the robotic arm moves the sewing template, and the sewing machine needle moves the thread.

[0036] The working process of this utility model is as follows: Preparation: Open the top hinge panel 2 and all auxiliary hinge panels.

[0037] Preliminary positioning: Place the pocket piece on the lower hinge plate 1, with its edge close to the first auxiliary strip.

[0038] First folding and positioning: According to the process requirements, fold a part of the garment piece upward along the predetermined folding line, and then cover it with the first auxiliary plate 3 so that the folded edge is close to its positioning edge 8.

[0039] Second folding and positioning: Continue with the subsequent folding operation, and then cover with the corresponding second auxiliary plate 4, using its positioning edge 8 and fishbone spikes 9 for precise positioning and fixation.

[0040] Pressing and sewing: Gently close the upper hinge plate 2, at which point the garment piece is stably constrained within the sewing template. The operator starts the sewing machine, and the needle moves along the first sewing groove 5, the second sewing groove 6, and the third sewing groove 7 in sequence, making loops at the first and second loop sewing grooves for reinforcement, gradually completing all the stitching of the slanted pocket of the trousers, and obtaining the sewn product.

[0041] Example 2 Building upon Example 1, to provide stronger fixing force, especially when handling thicker or slippery fabrics, magnetic suction parts 13, such as thin magnets and magnetically conductive metal sheets, can be embedded on the upper surface of the lower hinge plate 1, the lower surface of the upper hinge plate 2, and the upper surface of the auxiliary flip plate. When the template is closed, the corresponding upper and lower magnetic suction parts 13 attract each other, providing a uniform pressing force to the entire sewing board. The magnetic attraction enables the boards to fit tightly together, fixing the fabric layer sandwiched in the middle and ensuring that it will not be misaligned during sewing, greatly improving the positional stability of the garment pieces.

[0042] In addition, anti-slip strips 12, such as silicone strips, can be provided on all surfaces in contact with the fabric (such as the upper / lower surfaces of each board). The function of the anti-slip strips is to effectively prevent relative slippage between the fabric and the template during operation. The anti-slip strips 12 work in conjunction with the magnetic suction part 13 to provide multiple layers of anti-slip protection.

[0043] In this embodiment, the added anti-slip strips, magnetic suction parts, and other optimized designs enable it to stably meet the sewing requirements of different materials (such as smooth silk and heavy denim), and it has strong versatility and reliability.

[0044] Example 3 Based on any of the above embodiments, in order to further achieve automation and reduce manual intervention, the sewing template of this utility model can also be linked with automated sewing equipment.

[0045] Specifically, such as Figure 1 As shown, one or more cylinder holes 16 are provided at a specific location on the lower hinge plate 1. In this embodiment, one cylinder hole 16 is provided. The cylinder hole 16 is used in conjunction with a cylinder lifting mechanism (not shown in the figure) installed below the sewing machine's work platform. This cylinder lifting mechanism is programmed and controlled by the sewing machine's control system.

[0046] The cylinder lifting mechanism and control system are conventional mechanical principles and structures well known and used by those skilled in the art, and therefore will not be described in detail, but this will not affect the understanding of this embodiment.

[0047] Its linkage operation process is as follows: When the sewing machine needle completes the predetermined stitch path along the sewing groove, in actual operation, after the sewing machine needle finishes its stitching along the first sewing groove, the sensor will send a signal or the program will directly issue an instruction. After receiving the signal, the sewing machine control system will trigger the cylinder lifting mechanism. The cylinder's push rod quickly extends upward and pushes the lower hinge plate 1 of the sewing template through the cylinder hole 16, causing the entire sewing template to undergo a rapid lifting action. This lifting action will instantly create a gap between the lower hinge plate 1 and the work platform. The edges of the garment pieces that were previously pressed under the template can quickly detach and unfold under the action of this lifting force and airflow, i.e., be "blown" out or popped out, so as not to affect the needle from continuing to sew the garment pieces along the second sewing groove. This prevents the garment pieces pressed under the lower hinge plate from being sewn under the second sewing groove, causing sewing errors, saving manual operation and improving production efficiency.

[0048] In this embodiment, the function of automatically detaching the garment piece from the template after sewing is realized through the cooperation of the cylinder hole and the equipment lifting mechanism. This automates the operation that originally required manual intervention, which not only saves operation time, but more importantly, achieves seamless connection with automated sewing equipment, providing key node support for building a fully automated production line, and resulting in a qualitative leap in overall production efficiency.

[0049] The advantages of this design are demonstrated through the above embodiments: (1) Greatly improves sewing quality and consistency: The physical constraint of the sewing groove fundamentally eliminates the problem of crooked and skewed stitches caused by manual pushing. The auxiliary flip plate and auxiliary strip ensure that the position and angle of each fold are accurate, thereby achieving a high degree of uniformity in the seam alignment and straightness of all products, and significantly reducing the defect rate.

[0050] (2) Significantly reduces operational difficulty and training costs: This utility model transforms experience-dependent sewing skills into simple, template-based operations. New workers can quickly get started without long periods of practice, simply by following the fixed steps of "placement-folding-covering-sewing" to produce qualified products. This greatly shortens the training cycle, reduces reliance on skilled workers, and effectively saves the company's human resource costs.

[0051] (3) Improve production efficiency: The use of templates saves workers the time of repeatedly comparing and adjusting the fabric. The sewing machine can operate continuously and quickly along the guide groove, reducing intermediate stops and significantly shortening the sewing time of a single product, thus improving overall production efficiency.

[0052] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
