Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to an automatic sewing machine. Background Technology

[0002] In existing technologies, processing fabric edges through manual overlocking and binding can not only fix the fabric yarn to prevent fraying and avoid fraying, but also make the seams smooth and neat, thereby improving the appearance and texture of the finished product. This covers the treatment of shirt cuffs and jeans side seams in clothing production, the edge reinforcement of bed sheets and curtains in home textiles, and the edges of daily necessities such as dishcloths and washcloths, which can effectively improve production efficiency and finished product quality.

[0003] However, manual sewing has significant drawbacks, making it difficult to meet the demands of efficient and high-quality production. Manual sewing requires a high level of skill from the operator; worker fatigue or operational errors can easily lead to misalignment between the fabric edge and the overlock sewing machine, resulting in uneven seam width, crooked stitches, and other problems that affect the consistency of the finished product. Furthermore, the manual, piece-by-piece material handling method is inefficient, especially for batch production tasks, making it difficult to increase overall productivity and increasing labor costs due to prolonged repetitive work. In addition, the stability of manually controlling the fabric feed speed and angle is insufficient, easily causing interruptions in the fabric edge as it passes the overlock sewing machine, disrupting the seam continuity, increasing the risk of fabric unraveling, and failing to guarantee consistent processing quality. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sewing machine, which aims to at least solve the technical problems of poor consistency of finished products with manual sewing, low efficiency of mass production, and unstable processing quality in the prior art.

[0005] To achieve the above objectives, the present invention provides an automatic sewing machine, comprising:

[0006] A workbench, wherein a working surface is provided on the workbench, and a triaxial linear module and an overlock sewing machine are provided on the workbench;

[0007] A movable component, rotatably mounted on the triaxial linear module, is driven by the triaxial linear module to move along the X-axis, Y-axis and Z-axis directions and rotate in a plane parallel to the working plane;

[0008] A control system, which is electrically connected to the triaxial linear module and the overlock sewing machine;

[0009] The workbench is provided with a placement position for placing the material to be sewn, so that the moving component can be driven and controlled by the control system to move the material to be sewn from the placement position and drive the edge of the material to be sewn to continuously pass through the overlock sewing machine to sew the outer edge of the material.

[0010] Furthermore, the moving component is a pressure plate structure, which presses the material onto the working plane to drag the material along the X-axis, Y-axis and Z-axis directions and to rotate in a plane parallel to the working plane.

[0011] Furthermore, the triaxial linear module includes:

[0012] A three-axis moving device is mounted on the working plane;

[0013] A rotary drive assembly is mounted on the three-axis moving device to drive the rotary drive assembly to move along the X-axis, Y-axis and Z-axis directions via the three-axis moving device. The rotary drive assembly is driven to connect with the moving assembly to drive the moving assembly to rotate in a plane parallel to the working plane.

[0014] Furthermore, the three-axis moving device includes:

[0015] X-axis linear module, wherein the X-axis linear module extends along the X-axis direction;

[0016] A Y-axis linear module is mounted on the sliding end of the X-axis linear module, and the Y-axis linear module extends along the Y-axis direction.

[0017] A Z-axis linear module is mounted on the sliding end of the Y-axis linear module, and the Z-axis linear module extends along the Z-axis direction.

[0018] Furthermore, the rotation drive assembly includes:

[0019] A rotary motor, which is mounted on the three-axis moving device;

[0020] A drive rod, which is driven by the rotary motor to rotate the drive rod along its axis.

[0021] Furthermore, the drive rod is arranged vertically, and the drive rod is approximately perpendicular to the working plane.

[0022] Furthermore, the overlock sewing machine is installed on one side of the working plane, and the sewing needle of the overlock sewing machine is inserted into the working plane.

[0023] Furthermore, the movable component is detachably mounted on the triaxial linear module.

[0024] Furthermore, a positioning frame is provided on the workbench to form a placement position within the positioning frame, and at least one side of the positioning frame is open so that the movable component can be moved out of the placement position from the open side.

[0025] Furthermore, the working plane has an ejection position so that after the overlock sewing machine has finished sewing the outer peripheral edge of the material, the triaxial linear module drives the moving component to transport the material to the ejection position.

[0026] As can be seen from the above technical solution, the automatic edge-sewing machine of this utility model allows the material to be sewn to be placed in the designated position manually. The control system drives the three-axis linear module to move the material, realizing the automated handling, multi-directional movement, and rotation of the material. This ensures that the material edge continuously passes through the overlock sewing machine to complete the edge-sewing process. This design effectively reduces the reliance on human skill, reduces problems such as uneven edge width and crooked stitches caused by operational deviations, improves the consistency of finished products, and the automated batch processing mode improves production efficiency and overall capacity, reduces the labor costs caused by long-term repetitive operations, and achieves efficient and high-quality automated edge-sewing operations.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] For ease of understanding, in this application, the observer faces the appendix Figure 2 When observing, the observer's left side is designated as left, the observer's right side as right, the observer's front as down, the observer's back as up, the observer's top as back, and the observer's bottom as front. It should be noted that the terms "front end," "rear end," "left side," "right side," "middle," "above," and "below" used in this text indicate the orientation or positional relationship based on the accompanying drawings. They are used solely for the purpose of clearly describing this utility model and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Orientation can also be compared with other methods. Figure 1 As shown in the spatial coordinate system, the "left and right" direction is the X-axis direction, the "up and down" direction is the Z-axis direction, and the "front and back" direction is the Y-axis direction.

[0041] Please refer to the following: Figures 1 to 5This embodiment provides an automatic edge-sewing machine, including a worktable 100, a moving component 400, and a control system. The worktable 100 is provided with a working plane 110, a triaxial linear module 200, and an overlock sewing machine 300. The moving component 400 is rotatably mounted on the triaxial linear module 200, so that the moving component 400 is driven by the triaxial linear module 200 to move along the X-axis, Y-axis, and Z-axis directions and rotate in a plane parallel to the working plane 110. The control system is electrically connected to the triaxial linear module 200 and the overlock sewing machine 300. The worktable 100 is provided with a placement position 111 for placing the material to be sewn, so that the control system drives the moving component 400 to move the material to be sewn from the placement position 111 and drives the edge of the material to be sewn to continuously pass through the overlock sewing machine 300 to sew the outer peripheral edge of the material.

[0042] As can be seen, in this embodiment of the automatic edge-sewing machine, the material to be sewn is placed in the placement position 111 by the manual laborer. The control system can drive the triaxial linear module 200 to drive the moving component 400 to transport the material to be sewn, realizing the automated transport, multi-directional movement and rotation of the material to be sewn, so that the edge of the material continuously passes through the overlock sewing machine 300 to complete the edge-sewing process. This setting effectively reduces the dependence on manual skill, reduces problems such as uneven edge width and crooked stitches caused by operational deviations, improves the consistency of finished products, and the automated batch processing mode improves production efficiency and overall capacity, reduces the labor costs caused by long-term repetitive operations, and realizes efficient and high-quality automated edge-sewing operations.

[0043] In this embodiment, please refer to the following: Figures 1 to 4 The moving component 400 is a pressure plate structure, which presses the material onto the working plane 110 to drag the material along the X-axis, Y-axis and Z-axis directions and rotate it in a plane parallel to the working plane 110.

[0044] The pressure plate structure presses the material firmly onto the working plane 110, ensuring its stability and preventing deviation during handling and sewing. This avoids misalignment or irregular stitches caused by material slippage. Simultaneously, dragging and rotating the material while it is pressed ensures a stable relative position between the material edge and the overlock sewing machine 300, improving sewing accuracy and consistency. Furthermore, the pressure plate structure is highly adaptable to different materials, accommodating fabrics of varying thicknesses and textures, ensuring a stable pressing effect in various fabric processing applications and further guaranteeing the reliability of automated sewing.

[0045] In this embodiment, please refer to the following: Figures 1 to 4The three-axis linear module 200 includes a three-axis moving device 210 and a rotary drive assembly 220. The three-axis moving device 210 is mounted on the working plane 110, and the rotary drive assembly 220 is mounted on the three-axis moving device 210 to drive the rotary drive assembly 220 to move along the X-axis, Y-axis and Z-axis directions. The rotary drive assembly 220 is driven to connect with the moving assembly 400 to drive the moving assembly 400 to rotate in a plane parallel to the working plane 110.

[0046] The modular design clarifies the functional division of each part. The three-axis moving device 210 is specifically responsible for realizing the precise displacement of the moving component 400 in the X, Y, and Z axis directions. The rotary drive component 220 is solely responsible for driving the rotation of the moving component 400, making the control of each motion dimension more independent and precise, reducing motion interference. The modular layout also facilitates later maintenance and component replacement, reduces equipment maintenance costs, and further ensures the reliability of continuous operation of the automatic sewing machine.

[0047] Preferably, please refer to the following: Figures 1 to 4 The three-axis moving device 210 includes an X-axis linear module 211, a Y-axis linear module 212, and a Z-axis linear module 213. The X-axis linear module 211 extends along the X-axis direction, the Y-axis linear module 212 is mounted on the sliding end of the X-axis linear module 211 and extends along the Y-axis direction, and the Z-axis linear module 213 is mounted on the sliding end of the Y-axis linear module 212 and extends along the Z-axis direction.

[0048] Among them, by using linear modules independently set along three orthogonal directions, precise displacement control of the moving component 400 in three-dimensional directions in space is achieved. The movement of each axis is independent and does not interfere with each other, which can significantly improve the positioning accuracy and movement stability of the moving component 400. This step-by-step axis system design makes it easy to adjust the motion parameters (such as speed and stroke) of each axis according to actual operation requirements, adapting to the sewing requirements of materials of different sizes and shapes. At the same time, the modular axis system structure simplifies the assembly and debugging process of the equipment. If a certain axis system fails later, it can be replaced individually, reducing maintenance difficulty and cost, and further ensuring the efficient and stable operation of the automatic sewing machine.

[0049] Preferably, please refer to the following: Figures 1 to 4 The rotary drive assembly 220 includes a rotary motor 221 and a drive rod 222. The rotary motor 221 is mounted on the three-axis moving device 210, and the drive rod 222 is drivenly connected to the rotary motor 221 so that the drive rod 222 is driven to rotate along its axis by the rotary motor 221.

[0050] The drive rod 222 is directly driven to rotate by the rotary motor 221, forming a simple and efficient transmission path. This reduces energy loss and error accumulation in intermediate transmission links, significantly improving the rotational accuracy and response speed of the moving component 400. The direct drive connection between the drive rod 222 and the rotary motor 221 makes the control of the rotational action more direct and stable, ensuring the accuracy of the angle adjustment of the material during rotation, thereby guaranteeing the precise fit between the sewing trajectory and the material edge. At the same time, this structure is simple and compact, easy to assemble and maintain, reduces the probability of equipment failure, and further improves the reliability of the automatic sewing machine in complex trajectory sewing operations.

[0051] Preferably, please refer to the following: Figures 1 to 4 The drive rod 222 is set vertically, and the drive rod 222 is set approximately perpendicular to the working plane 110.

[0052] The vertically arranged drive rod 222 enables the rotational driving force to be transmitted in a direction perpendicular to the working plane 110, ensuring that the rotation center axis of the moving component 400 remains perpendicular to the working plane 110. This ensures the accuracy of angle adjustment when the material rotates in a plane parallel to the working plane 110, avoiding material offset or skewed seam track caused by the tilt of the rotation axis. At the same time, the vertically arranged drive rod 222 reduces the occupation of the working space on the working plane 110, reduces the risk of interference with the overlock sewing machine 300 or the material, provides more sufficient operating space for the movement and rotation of the material, and further improves the stability and safety of the equipment operation.

[0053] In this embodiment, please refer to the following: Figures 1 to 5 The overlock sewing machine 300 is installed on one side of the working plane 110, and the sewing needle of the overlock sewing machine 300 is inserted into the working plane 110.

[0054] This layout creates a reasonable working height difference between the sewing needle of the overlock sewing machine 300 and the working plane 110, ensuring that the edges of the material naturally conform to the working position of the sewing needle when it moves on the working plane 110, reducing misalignment of the sewing edges due to height mismatch. At the same time, the side-mounted overlock sewing machine 300 avoids occupying the main operating area of ​​the working plane 110, reserving sufficient space for the moving component 400 to handle and rotate materials, reducing the risk of motion interference between equipment parts. In addition, the design of the sewing needle penetrating the working plane 110 allows the sewing operation to be closer to the edge of the material, improving the fit accuracy between the stitch and the edge, and further ensuring the stability of the sewing quality.

[0055] In this embodiment, the movable component 400 is detachably mounted on the triaxial linear module 200.

[0056] When processing materials of different thicknesses and materials, the adaptable moving component 400 can be quickly disassembled and replaced, greatly improving the equipment's adaptability to diverse materials. If the moving component 400 is worn or malfunctions, the detachable design allows for individual disassembly, repair, or replacement without disassembling the entire triaxial linear module 200, reducing maintenance difficulty and cost. At the same time, this design also facilitates individual cleaning or maintenance of the moving component 400, extending the service life of the components and further ensuring the long-term stable operation of the automatic sewing machine.

[0057] In this embodiment, please refer to the following: Figures 1 to 5 The workbench 100 is provided with a positioning frame 120 to form a placement position 111 in the positioning frame 120. At least one side of the positioning frame 120 is provided with an opening so that the moving component 400 can be moved out of the placement position 111 from the opening side.

[0058] The positioning frame 120 provides a clear initial placement boundary for the material to be sewn, ensuring that the material is placed in a consistent position each time, avoiding the impact of manual material placement deviation on subsequent sewing accuracy and improving the consistency of automated operations. The opening design on one side of the frame provides a smooth material picking channel for the moving component 400, allowing the moving component 400 to quickly transport materials from the opening without detouring, reducing material picking time and improving overall operation efficiency. At the same time, the positioning frame 120 also plays a protective role during the material placement stage, reducing the risk of damage to the material due to collision or displacement, and further ensuring processing quality.

[0059] In other possible implementations, the placement position 111 can be marked by engraving lines on the working plane 110; this simple alternative should also be within the scope of protection of this utility.

[0060] In this embodiment, the working plane 110 has an ejection position so that after the overlock sewing machine 300 has finished sewing the outer peripheral edge of the material, the triaxial linear module 200 drives the moving component 400 to transport the material to the ejection position.

[0061] Once the seams are completed, the moving component 400 can directly transport the material to the designated ejection position, achieving automated connection between processing and discharge. This avoids material accumulation in the processing area from affecting subsequent operations, improves the continuity of the overall production process, and further enhances production efficiency. In addition, a clearly defined discharge position can standardize the material flow path, reduce the risk of damage or contamination of materials during transfer, and ensure the stability of finished product quality.

[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0063] This utility model's automatic edge-sewing machine allows manual placement of the material to be sewn into position 111. The control system drives the triaxial linear module 200 to move the moving component 400, thus automating the material's handling, multi-directional movement, and rotation. This ensures the material's edges continuously pass through the overlock sewing machine 300 to complete the edge-sewing process. This design effectively reduces reliance on manual skill, minimizing issues like uneven edge width and skewed stitches caused by operational errors, improving finished product consistency. Furthermore, the automated batch processing mode increases production efficiency and overall capacity, reduces labor costs associated with repetitive long-term operations, and achieves efficient and high-quality automated edge-sewing operations.
