Description

Technical Field

[0001] This application relates to the field of textile sewing technology, and in particular to a sleeve attaching fabric assembly and an automatic sleeve attaching machine. Background Technology

[0002] In the sewing of clothing, the process of attaching sleeves is usually involved, which requires the use of a sleeve attaching machine for semi-automatic sleeve attachment.

[0003] When attaching cylindrical sleeves, after the sleeve-attaching machine finishes sewing a section of fabric, the next section is manually pulled into the sewing area. Simultaneously, the remaining fabric (excluding the sewing area) needs to be neatly arranged to ensure the smoothness of the sewing area. If the fabric is not neatly arranged in a timely or effective manner, the sewn part will twist and become knotted, affecting the sleeve-attaching process. Because fabric neatness requires manual intervention, it is not only time-consuming and labor-intensive but also costly, failing to provide a supportive guarantee for the automation and intelligentization of sleeve attachment. Summary of the Invention

[0004] The purpose of this application is to provide a sleeve attaching support assembly and an automatic sleeve attaching machine, which can place excess fabric into the sleeve attaching support assembly during sleeve attaching. The sleeve attaching support assembly drives the fabric to rotate, so that the remaining part of the fabric in the sleeve attaching support assembly moves together with the sewn part of the fabric outside the sleeve attaching support assembly, eliminating kinks and ensuring smooth sleeve attaching.

[0005] To achieve the above objectives, this application provides a sleeve support assembly, including a drive assembly and a support assembly. The drive assembly is connected to the support assembly, and the drive assembly is used to drive the support assembly to rotate. The support assembly is used to fix the remaining part of the fabric except for the sewing part, so that the remaining part of the fabric moves together with the sewing part and eliminates the kinking between the remaining part of the fabric and the sewing part.

[0006] In some embodiments, the fabric support assembly includes a fabric support wheel and a fabric fixing member. The fabric support wheel is a hollow circle, and the interior of the fabric support wheel is used to support the fabric. The fabric fixing member is arranged circumferentially inside the fabric support wheel and is used to fix the supported fabric.

[0007] In some embodiments, the fabric fastener protrudes toward the inner center of the support roller, and the fabric fastener is curved so that when the support roller rotates in a direction opposite to the curvature direction of the fabric fastener, the fabric fastener hooks the fabric.

[0008] In some embodiments, the inner circumferential of the support roller is further provided with a protruding structure, which is used to increase the contact area between the support roller and the fabric.

[0009] In some embodiments, the sleeve support assembly further includes a support roller base, on which the drive assembly is mounted, and a support assembly is also mounted, with the support assembly assembled to the support assembly.

[0010] In some embodiments, the drive assembly includes a drive member and a cloth drive wheel. The drive member is connected to the cloth drive wheel and is used to drive the cloth drive wheel to rotate. The cloth drive wheel is in pressure contact with the outer periphery of the cloth assembly so that the cloth assembly is driven to rotate by the cloth drive wheel.

[0011] In some embodiments, the support assembly includes a support roller bracket, the support roller bracket is mounted on the support roller base, and the support assembly is assembled to the support roller bracket so that the support assembly is axially limited by the support roller bracket.

[0012] In some embodiments, the support assembly further includes a cloth driven wheel and a cloth tensioning wheel. The cloth driven wheel is mounted on the cloth wheel base and presses against the outer periphery of the cloth assembly. The cloth tensioning wheel is mounted on the cloth wheel bracket and presses against the outer periphery of the cloth assembly, so that the cloth assembly is limited in the circumferential direction by the cloth driving wheel, the cloth driven wheel, and the cloth tensioning wheel.

[0013] In some embodiments, the pressure exerted by the tensioning wheel on the cloth assembly is adjustable.

[0014] This application also provides an automatic sleeve attaching machine, including the aforementioned sleeve attaching support assembly, and a sewing machine body, wherein the sleeve attaching support assembly is arranged on one side of the sewing machine body.

[0015] Compared with the above-mentioned background technology, the sleeve support assembly provided in this application includes a drive assembly and a support assembly. The drive assembly is connected to the support assembly. The drive assembly is used to drive the support assembly to rotate. The support assembly is used to fix the remaining part of the fabric except for the sewing part, so that the remaining part of the fabric moves together with the sewing part and eliminates the kinking between the remaining part of the fabric and the sewing part.

[0016] This sleeve-attaching support assembly needs to be used in conjunction with the sewing machine part of an automatic sleeve-attaching machine, i.e., the main body of the sewing machine. During sleeve attachment, the sewing part of the fabric is sewn within the main body of the sewing machine. As the main body of the sewing machine feeds the fabric into the sewing part, the rest of the fabric, excluding the sewing area, also moves. Before this, the excess fabric is placed into the sleeve-attaching support assembly. The sleeve-attaching support assembly rotates the fabric, and during sleeve attachment, the remaining fabric in the sleeve-attaching support assembly moves together with the sewing part of the fabric outside the sleeve-attaching support assembly, keeping the fabric in a relaxed state. This eliminates any kinking between the excess fabric and the sewing part of the fabric, ensuring smooth sleeve attachment. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Currently, attaching cylindrical sleeves requires manual intervention. Because the sleeve piece is tubular, after sewing one section of fabric, the next section needs to be manually pulled into the sewing area, and the remaining fabric needs to be straightened to ensure the flatness of the sewing area. Otherwise, the sewn part of the fabric and the rest of the fabric will twist, forming a rope-like shape. When the sleeve attachment process is fully automated without manual intervention, this situation will affect the flatness of the fabric in the sewing area, and may also cause the fabric to be pulled, resulting in excessive tension beyond expectations, thus affecting the quality of the sleeve attachment and even preventing the sleeve attachment process from proceeding smoothly.

[0025] To address the aforementioned technical problems, this application provides a sleeve-attaching fabric assembly that solves the problem of garments twisting during the sleeve-attaching process.

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the sleeve support assembly provided in an embodiment of this application. Figure 2 The front view of the sleeve-attaching fabric assembly provided in the embodiments of this application, excluding the base of the fabric-attaching roller.

[0027] The sleeve support assembly mainly includes a drive assembly and a support assembly. The drive assembly provides driving force, while the support assembly fixes the fabric and drives the fabric to rotate.

[0028] In this embodiment, the drive component is connected to the fabric support component. The drive component drives the fabric support component to rotate, and the fabric support component fixes the remaining part of the fabric except for the sewing part, so that the remaining part of the fabric moves together with the sewing part, thereby eliminating the kinking between the remaining part of the fabric and the sewing part.

[0029] This sleeve-attaching support assembly needs to be used in conjunction with the sewing machine part of an automatic sleeve-attaching machine, i.e., the main body of the sewing machine. During sleeve attachment, the sewing part of the fabric is sewn within the main body of the sewing machine. As the main body of the sewing machine feeds the fabric into the sewing part, the rest of the fabric, excluding the sewing area, also moves. Before this, the excess fabric is placed into the sleeve-attaching support assembly. The sleeve-attaching support assembly rotates the fabric, so that during sleeve attachment, the remaining fabric in the sleeve-attaching support assembly moves together with the sewing part of the fabric outside the sleeve-attaching support assembly. This keeps the fabric in a relaxed state, rather than twisted like a rope, thus eliminating the kinking between the excess fabric and the sewing part of the fabric and ensuring smooth sleeve attachment.

[0030] It is important to note that the core improvement of this embodiment lies in allowing excess fabric to move along with the fabric in the sewing area, keeping both parts of the fabric in a relatively relaxed state, thereby ensuring the smooth progress of the sleeve attachment process. In addition, there are multiple implementation schemes for the drive assembly and the fabric support assembly. For example, the fabric support assembly can adopt a claw mechanism, which can clamp the fabric. The base of the claw mechanism can rotate: before attaching the sleeve, the excess garment piece (excess part of the fabric) is straightened and the claw mechanism clamps the garment piece. During the sleeve attachment process, as the fabric in the sewing area (the sewn part of the fabric) rotates, the claw mechanism also clamps the garment piece and rotates, matching the speed to achieve synchronous movement within a certain range.

[0031] In one specific embodiment, the fabric support assembly includes a fabric support roller 5 and a fabric fastener.

[0032] In this embodiment, the support roller 5 is a hollow circle, and the inside of the support roller 5 is used to support the fabric. The fabric fixing member is arranged circumferentially inside the support roller 5 and is used to fix the supported fabric.

[0033] like Figure 1 and Figure 2 As shown, the circular, hollow fabric roller 5 is regarded as a cylinder. When attaching the sleeve, the excess fabric is placed into the cylinder, and the fabric fixing component fixes the fabric. The cylinder drives the fabric to rotate, which ensures that the excess fabric in the cylinder and the fabric in the sewing area always remain in a relatively relaxed state, effectively ensuring the smooth progress of the sleeve attachment process.

[0034] It is important to note that there are various implementation schemes for the fabric fixing component, including but not limited to adhesive fixing and suction fixing. For example, for adhesive fixing, adhesive tape can be used inside the support roller 5. When the support roller 5 rotates, the tape adheres to the fabric due to its adhesiveness. For suction fixing, a suction system can be used inside the support roller 5. When the support roller 5 rotates, the suction system adheres to the fabric due to its suction force. Furthermore, the adhesiveness of the tape in adhesive fixing can be designed, and the suction force of the suction system in suction fixing can be adjusted, so that the fabric fixing effect allows the fabric to detach from the support roller 5 when it is driven to or near the highest point, thereby achieving fabric flipping.

[0035] In one specific embodiment, the fabric fastener protrudes toward the inner center of the support roller 5, and the fabric fastener is curved.

[0036] In this embodiment, the protruding, curved fabric fastener is regarded as a barb. When attaching the sleeve, the fabric support wheel 5 rotates in the opposite direction to the bending direction of the fabric fastener, and the fabric fastener hooks the fabric.

[0037] like Figure 1As shown, the hook-type fabric fastener bends clockwise, while the fabric support wheel 5 rotates counterclockwise. The ends of the hook-type fabric fasteners all face the counterclockwise rotation direction. When attaching the sleeve, the fabric support wheel 5 rotates counterclockwise, and the hook-type fabric fasteners hook the fabric, securing it and causing the fabric to rotate together with the fabric support wheel 5.

[0038] It should be noted that the bending angle of the hook-type fabric fastener should not be too large, so that the fabric can be smoothly hooked at the lowest point and smoothly released near the highest point.

[0039] In some embodiments, the inner circumferential of the top roller 5 is further provided with a raised structure.

[0040] In this embodiment, the protruding structure is arranged between adjacent fabric fixing members. The protruding structure increases the contact area between the support roller 5 and the fabric, thereby enhancing the friction between the support roller 5 and the fabric and improving the support and fixing effect of the support roller 5 on the fabric.

[0041] In one specific embodiment, the sleeve-attaching fabric support assembly further includes a fabric support wheel base 1. The fabric support wheel base 1 serves as the supporting foundation for the sleeve-attaching fabric support assembly. The fabric support wheel base 1 is equipped with a drive assembly and a support assembly, and the fabric support assembly is assembled via the support assembly. In use, the fabric support wheel base 1 is fixed to one side of the sewing machine body. The fabric support assembly supports and secures the inserted fabric. The drive assembly drives the fabric support assembly to rotate, so that the excess fabric in the fabric support assembly moves together with the sewn portion of the fabric in the sewing machine body, eliminating kinks.

[0042] It should be noted that there are multiple implementation schemes for the drive component, that is, there are multiple ways to drive the support roller 5 in the support assembly. For example, it can be driven by a synchronous belt or synchronous pulley, by a gear or rack, by a rotary slide, or by an additional mechanism (such as a ratchet mechanism or a grooved wheel mechanism) to drive the support roller 5 to rotate intermittently or continuously, or by other transmission methods such as hydraulic transmission.

[0043] In one specific implementation, the drive assembly includes a drive element and a feed drive wheel 4.

[0044] In this embodiment, the driving member is connected to the brush drive wheel 4. The driving member drives the brush drive wheel 4 to rotate. The brush drive wheel 4 presses against the outer periphery of the brush wheel 5 in the brush assembly. The friction between the brush drive wheel 4 and the brush wheel 5 is used to make the brush wheel 5 in the brush assembly rotate by the brush drive wheel 4.

[0045] For example, the driving component is a motor 7. The output end of the motor 7 is directly connected to the rotating shaft of the cloth drive wheel 4. The cloth drive wheel 4 is rotatably mounted on the cloth wheel base 1. The motor 7 drives the cloth drive wheel 4 to rotate, which in turn drives the cloth wheel 5 to rotate, thereby causing the cloth placed in the cloth wheel 5 to rotate and flip.

[0046] In some embodiments, the support assembly includes a roller bracket 2.

[0047] In this embodiment, the support roller bracket 2 is divided into front and rear groups. The support roller bracket 2 is installed on the support roller base 1. The support roller assembly is assembled between the front and rear groups of support roller bracket 2. The support roller assembly is limited in the axial direction of the support roller assembly by the front and rear groups of support roller bracket 2, so that the support roller 5 has no movement in other directions except for rotation.

[0048] In some embodiments, the support assembly further includes a cloth driven wheel 3 and a cloth tensioning wheel 6.

[0049] In this embodiment, the driven roller 3 is mounted on the roller base 1, and the driven roller 3 and the roller base 1 are also rotatably assembled. The driven roller 3 is in close contact with the outer periphery of the roller assembly. The tension roller 6 is mounted on the roller bracket 2, and the tension roller 6 and the roller bracket 2 are rotatably assembled. The tension roller 6 is in close contact with the outer periphery of the roller assembly. Through the driven roller 4, the driven roller 3, and the tension roller 6, the roller assembly is limited in the circumferential direction, so that the roller 5 has no movement in any direction except rotation.

[0050] Furthermore, the outer surface of the support roller 5 is patterned to increase friction with the wheel body. The support roller drive roller 4, support roller driven roller 3, and support roller tensioning roller 6 are arranged in a triangle, with the support roller tensioning roller 6 located at the upper corner and the support roller drive roller 4 and support roller driven roller 3 located at the two lower corners, thereby increasing the stability of the support roller 5. In use, the support roller 5 is confined in the middle of the support roller bracket 2, and the support roller 5 is pressed against the support roller drive roller 4 and support roller driven roller 3 by the support roller tensioning roller 6; when the motor 7 drives the support roller drive roller 4, the support roller 5 rotates under the action of friction; the support roller driven roller 3 and support roller tensioning roller 6 also rotate under the action of friction, playing an auxiliary role.

[0051] In some embodiments, the pressure exerted by the cloth tensioning wheel 6 on the cloth assembly is adjustable.

[0052] In this embodiment, the mounting hole of the cloth tensioning wheel 6 on the cloth tensioning wheel bracket 2 is a waist-shaped hole, which is used to adjust the height of the cloth tensioning wheel 6, thereby adjusting the degree of pressure of the cloth tensioning wheel 6 on the cloth tensioning wheel 5.

[0053] In one specific embodiment, the sleeve-attaching support assembly is used in an automatic sleeve-attaching machine. During operation, the entire piece of fabric, except for the sleeve-attaching portion of the cylindrical sleeve, is straightened and placed into the support roller 5, draped over the lower inner wall of the support roller 5. The support roller 5 is hollow inside, with small protrusions evenly distributed on its inner wall and barbs facing the same direction (towards the counterclockwise rotation direction). As the support roller 5 rotates counterclockwise as shown in the figure, the fabric draped over the lower inner wall of the support roller 5 is caught by the barbs and rotates with the barbs. When it rotates to near its highest point, the fabric detaches from the barbs and falls off under the influence of gravity, draping back over the lower inner wall of the support roller 5, thus achieving the fabric flipping.

[0054] Based on the above principle, the excess fabric of the garment is folded over, and this folding action is basically synchronized with the movement of the fabric in the round sleeve sewing area. This effectively ensures the smooth execution of the sleeve attachment. The rotation speed of the support roller 5 does not need to be exactly the same as the sewing speed; it is sufficient that their movements are synchronized within a certain range.

[0055] This application also provides an automatic sleeve attaching machine, including the aforementioned sleeve attaching support assembly, and a sewing machine body, with the sleeve attaching support assembly arranged on one side of the sewing machine body.

[0056] This automatic sleeve-attaching machine should possess all the beneficial effects of the aforementioned sleeve-attaching fabric support assembly. The fabric support assembly replaces the manual action of turning the fabric during the machine sleeve-attaching process to ensure smooth attachment. This facilitates the automation of the sleeve-attaching process and reduces labor costs. Furthermore, the fabric support assembly solves the problem of fabric twisting together with other fabrics in the sewing area during fully automatic sleeve-attaching machine operation, leading to poor attachment quality or even failure to complete the process. Currently, there are no similar mechanisms on the market, filling a market gap.
