Description

Technical Field

[0001] The present invention relates to a method for cutting a multi-layer structure-intensive fabric and a cutting system applying the method. Background Art

[0002] A structure-intensive fabric is a textile fabric with a tight structure, usually woven from high-density fibers. The advantages of this fabric include excellent durability, moisture resistance, warmth retention, and appearance texture. Structure-intensive fabrics are usually used in the production of high-end clothing, outdoor products, automotive interiors, and other fields that require high quality and performance.

[0003] Due to the outstanding advantages of the structure-intensive fabric, it is now used as the fabric for down jackets. When used as a clothing fabric, the fabric generally needs to be laid flat in multiple layers and then lofted and cut according to the design of the clothing style.

[0004] However, due to the airtight characteristic of the structure-intensive fabric, after the fabric is pulled out and laid flat in multiple layers from the cloth roll, there will be air between the layers of the fabric. If cutting is directly carried out, the fabric will shift between layers, resulting in inconsistent cut pieces and affecting subsequent production.

[0005] Therefore, for the structure-intensive fabric, after the fabric laying is completed, a plastic film needs to be covered on the surface, and then a cutting machine with the Chinese patent publication number CN212335622U is used to evacuate the space inside the plastic film, in an attempt to discharge the air between the fabric layers so that the fabric fits together, and then cutting is carried out.

[0006] However, due to the long length of the fabric cutting table in industrial production, it is very difficult to completely discharge the air between the fabric layers only by evacuating at both ends. Accordingly, a cloth pressing and film covering structure and a cutting bed with the Chinese patent publication number CN113638213A, on the basis of film covering, adopt a roller pressing device to discharge the air between the fabric layers by rolling, while cutting and rolling, so as to prevent relative sliding between the fabrics during the cutting process and stabilize the cutting quality. However, driving the air away by rolling itself will drive the fabric to slide, causing the movement of the remaining fabric; and when the fabric is cut, it does not move in a single-channel linear motion. It often reciprocates in a region. However, when the roller rolls on the cut pieces that have been cut, it will cause the cut pieces to be misaligned and even move into the uncut region, resulting in damage to the cut pieces.

[0007] However, in the actual cutting process of the above-mentioned structure-intensive fabric, there is still a phenomenon that the air discharge is not thorough, resulting in relative sliding between the fabric layers and affecting the cutting quality.

[0008] Therefore, it is necessary to improve the method of exhausting air for the cutting of multi-layer structured dense fabrics, so that the air between the fabric layers can be fully exhausted, and the cutting quality of the fabric can be improved. Summary of the Invention

[0009] The purpose of the present invention is to provide a cutting method and system for multi-layer structured dense fabrics. Through drilling, combined with two times of film covering, air suction, and roller pressing to expel air, the air between the multi-layer structured dense fabrics can be fully excluded. Furthermore, during subsequent cutting, the fabrics are not prone to displacement, so that the sizes of the cut pieces can be designed more accurately, the allowance during sewing can be reduced, and more layers of fabrics can be cut, improving the efficiency of sewing and cutting, and thus improving the production efficiency of clothing.

[0060] The following further elaborates on the specific embodiments of the present invention with reference to the accompanying drawings.

[0061] When batch cutting multi-layer structured dense fabric, the air between the fabric layers cannot be smoothly exhausted, resulting in the fabric being easily affected by the internal air during the cutting process, causing slippage and affecting the cut pieces. The present invention proposes a cutting method and system for multi-layer structured dense fabric. Among them, the cutting method for multi-layer structured dense fabric is as follows:

[0062] Step 1: Lay the fabric; Pull out the structurally dense fabric from the fabric roll according to production needs, lay it flat on the cutting table; and stack layer by layer until there are enough fabric layers; During this process, air will enter between the fabric layers.

[0063] Step 2: First lamination; Cover the surface of the topmost fabric layer with a layer of plastic film.

[0064] Step 3: First air suction; Suction the air inside the plastic film to initially discharge the air, make the fabrics roughly fit together for initial positioning; At this time, due to the characteristics of the structurally dense fabric, there will still be a small amount of air between the fabric layers, especially in the areas far from the air suction port, where there will still be an appropriate amount of air that cannot be sucked out due to the attenuation of the suction force.

[0065] Step 4: Identify and drill holes;

[0066] Layout; The CAD system performs layout on the fabric, that is, splice different cut pieces A together as much as possible to make full use of the fabric to form a layout diagram; Identify the gaps between cut piece A and cut piece A`, and design ventilation holes B at the positions with appropriate sizes, as Figure 1 shown;

[0067] Drill holes; According to the hole positions, the system automatically drills holes or manually drills holes;

[0068] When using automatic hole drilling, the system inputs the hole position diagram to the automatic drilling machine and then drills holes; When using manual hole drilling, according to the CAD projection diagram, manually mark the hole drilling points at the cut piece gap part, and then operate the drilling machine to drill holes.

[0069] Step 5: First roll pressing to expel air; Use a pressure roller with the same width as the cutting table to roll press on the fabric, so as to discharge the air between the fabrics through the ventilation holes B and both sides of the fabric width.

[0070] Step 6: Second lamination; After the first lamination, the film has been damaged after drilling;

[0071] Therefore, after Steps 4 and 5, laminate again, that is, cover the surface of the topmost fabric layer with a layer of plastic film.

[0072] The drilled plastic film covered in Step 2 can be removed or retained according to the situation after Step 5.

[0073] Step 7: Second air suction; Suction the air inside the plastic film to further discharge the air, make the fabrics completely fit together to achieve positioning.

[0074] During the second air suction process, in coordination with the air suction process, the second roller pressing can expel air, that is, use a pressure roller to roll over the surface of the plastic film. Through extrusion, the remaining air between the fabrics is further discharged through the ventilation holes B and both sides of the fabric width, so that the fabrics are completely adhered together.

[0075] Step 8: Cutting; Cut the fabric according to the layout diagram. When cutting, perform the cutting in sequence according to the length direction of the fabric; during the cutting process, the pressure roller follows and presses above the uncut area to prevent air from entering the subsequent fabric again after cutting the plastic film and the fabric. After the cutting is completed, take off the cut piece A according to the drawing.

[0076] In the above step 4, the ventilation holes B can be automatically arranged and designed in the CAD system. For reference, please refer to the applicant's prior application, the calculation method, system and equipment for intelligent cutting of multi-layer structured fabrics in the cutting process of garment manufacturing enterprises with the Chinese Patent Publication No. CN118095568A.

[0077] According to the above cutting method for multi-layer structured fabrics, the cutting bed needs to be modified to have the functions of drilling and roller pressing, so as to realize steps 4, 5, and 7.

[0078] Therefore, the present invention further provides a cutting system for multi-layer structured fabrics, which involves the structural improvement of the cutting bed.

[0079] As Figure 2 shown, a gantry 21 that can move horizontally is provided on the cutting platform 1, a head 22 that can move vertically is provided on the gantry 21, and a cutting tool device 23 is installed on one side of the head 22.

[0080] The improvement of the present invention is that a drilling device 3 is additionally installed on the other side of the head 22. A drill bit 31 is installed at the bottom of the drilling device 3, and holes can be drilled at the gap positions of the cut piece A according to the cut piece layout diagram, so as to form a number of ventilation holes B on the fabric. Then, a film is covered, and the multi-layer structured fabrics in the film are sucked air. The air between the fabrics can be discharged through the ventilation holes B, so that the fabrics in the fabric stack are fully adhered together, reducing the presence of air. Subsequently, start the cutting tool device 23 of the head 22 and cut according to the cut piece layout diagram to form the required cut piece A.

[0081] The internal structure of the drilling device 3 is as Figure 3 、 Figure 4 shown. For further reference, please refer to Figure 5 , which is a drill device that can move up and down, including a drilling mechanism and a lifting mechanism.

[0082] The drilling mechanism is provided with a replaceable drill bit 31 at the bottom. The drill bit 31 is a flat-bottom drill bit with a bottom plane 311. The drill bit 31 is installed at the bottom of the drill rod 32 through a drill chuck 33. The upper part of the drill rod 32 is provided with a rotary drive device, including a gear transmission device composed of a driven gear 34 and a driving gear 35. The driven gear 34 is sleeved and installed on the outer side of the upper part of the drill rod 32, while the driving gear 35 is connected to the driving motor 36. In this embodiment, a speed reducer 37 is provided between the driving gear 35 and the driving motor 36. The driving motor 36 is preferably a pneumatic rotary motor.

[0083] The drilling mechanism is installed at the bottom of the lifting plate 41. Among them, the drill rod 32 is installed at the bottom of the lifting plate 41 through a rotating mechanism 38, and the speed reducer 37 is directly fixed at the bottom of the lifting plate 41.

[0084] Furthermore, the drill bit 31 is a hollow drill bit, and the drill rod 32 is also a hollow drill rod. The rotating mechanism 38 is a rotary joint, and the rotating part 381 is fixedly connected to the drill rod 32. The fixed body of the rotating mechanism 38 is installed on the lifting plate 41, and a fixed joint 382 is provided on one side of the fixed body, which is connected to an external negative pressure generator. When the drill bit 31 works, the negative pressure generator is driven by compressed air to work, generating negative pressure in the drill rod cavity 321 inside the drill rod 32 and the drill bit cavity 312 inside the drill bit 31, so that the debris generated when the drill bit 31 cuts the fabric and the finally cut circular fabric piece are both sucked away by the negative pressure, avoiding residue and affecting subsequent operations. Moreover, when the drill bit 31 utilizes negative pressure, it can also accelerate the air circulation of the drilling components of the drill bit 31 for cooling.

[0085] The lifting mechanism includes a lifting plate 41. A lifting drive cylinder 42 is installed on the lifting plate 41. The piston rod of the lifting drive cylinder 42 is connected to the lifting plate 41 through a drive seat 421, driving the lifting plate 41 to lift and lower, thereby driving the drill bit 31 to move up and down. The lifting drive cylinder 42 is a damping cylinder, and it slowly descends after being filled with compressed air.

[0086] Furthermore, the lifting plate 41 is installed on the machine head 22 through a guiding mechanism. The slider 43 of the guiding mechanism is fixed to the lifting plate 41, and the slide rail 44 of the guiding mechanism is connected to the bracket of the machine head 22. The slider 43 cooperates with the slide rail 44. Preferably, multiple sets of guiding mechanisms are installed around the lifting plate 41 to improve the stability of its lifting movement process.

[0087] Furthermore, a limit block 45 is provided at the lower part of the slide rail 44 of one of the guiding mechanisms. The position of the limit block 45 on the slide rail 44 can be adjusted, thereby limiting the downward movement limit position of the slide rail 44, the lifting plate 41, and the drilling mechanism, especially the bottom plane 311 of the drill bit 31.

[0088] The cutting machine for drilling and exhausting air from a multi-layer structure dense fabric of the present invention has pneumatic components as the driving elements of the drilling device 3, so only an air source needs to be arranged.

[0089] When the cutting machine for drilling and exhausting air from a multi-layer structure dense fabric of the present invention drills holes in a multi-layer structure dense fabric stack, first, according to the layout drawing, the gantry 21 and the machine head 22 move, driving the drill bit 31 above the position of the ventilation hole B where drilling is required. Then, the air supply is turned on. At this time, the driving motor 36 and the lifting driving cylinder 42 work simultaneously, and the negative pressure generator also works accordingly. The lifting driving cylinder 42 drives the lifting plate 41 to slowly descend, so that the drill bit 31 contacts the multi-layer structure dense fabric stack, and drills the ventilation hole B at the specified position; by adjusting the position of the limit block 45, the bottom plane 311 of the drill bit 31 can just drill through the bottommost fabric layer without damaging the cutting platform 1; during the drilling process of the drill bit 31, debris and hole pieces are discharged to the waste collection box through the drill bit cavity 312 and the drill rod cavity 321 under the action of the negative pressure generator for centralized treatment.

[0090] The drill bit 31 drills holes vertically in the multi-layer structure dense fabric stack, indirectly pressing the fabric layers together at the position of the ventilation hole B, realizing fiber connection between the fabric layers, thereby positioning the fabric layers and reducing slippage.

[0091] After the drill bit 31 finishes drilling, the lifting driving cylinder 42 drives in the reverse direction, driving the drill bit 31 to rise; then the air supply is cut off. At this time, the drill bit 31 stops rotating, and the negative pressure generator also stops working; the gantry 21 and the machine head 22 drive the drilling device 3 to move above the position of the next ventilation hole B where drilling is required, and the air supply is started again for drilling until all drilling is completed.

[0092] The cutting machine of the present invention can be formed by installing the drilling device 3 on the machine head 22 of the existing cutting machine, and only needs to connect the air supply pipe, and then recalibrate the X-axis (lateral movement) coordinate of the drill bit 31 of the drilling device 3 in the cutting machine control system, which is convenient for drilling the multi-layer structure dense fabric stack. Then, combined with the subsequent film covering and air suction steps, the air between the fabrics can be fully discharged, thereby improving the stability during the subsequent cutting process.

[0093] As Figure 6 、 Figure 7 shown, on the cutting platform 1, relative to the cutting device 2, there is also a roller pressing device 5, and the roller pressing device 5 can move freely along the transverse direction of the cutting platform 1. Further as Figure 8As shown in the figure, there is a rubber roller 51 with the same width as the cutting platform 1 above the rolling device 5. Both ends of the rubber roller 51 are mounted on the rubber roller bracket 52. The rubber roller 51 is rotatably connected to the rubber roller bracket 52 freely. The bottom of the rubber roller bracket 52 is connected with a pressurizing cylinder 53; the piston rod of the pressurizing cylinder 53 is connected to the bottom of the rubber roller bracket 52, and the cylinder body of the pressurizing cylinder 53 is installed on the moving platform 54, and the moving platform 54 is equipped with a moving trolley 55. According to the cutting requirement, the rolling device 5 is pushed to the cutting platform 1, and then the pressurizing cylinder 53 is started to lower the rubber roller 51 together with the rubber roller bracket 52, so that the rubber roller 51 is pressed tightly on the multi-layer structure dense fabric stack on the cutting platform 1. Subsequently, according to the need, the moving trolley 55 is started, so as to drive the rolling device 5 to move along the cutting platform 1. Through the extrusion of the multi-layer structure dense fabric stack by the rubber roller 51, the air between the fabrics is extruded and finally discharged from the ventilation holes B and both sides of the fabric width.

[0094] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
