Description

Technical Field

[0001] This utility model belongs to the field of coding machine technology, specifically a fabric coding machine. Background Technology

[0002] After the garment fabric pieces are cut, they need to be marked with numbers to facilitate subsequent processing and production. Marking machines are highly automated and widely used in large-scale fabric production and processing, such as textile factories and dyeing factories. They can meet the needs of double-sided marking, which can reduce labor and time costs, improve efficiency, and provide high accuracy in marking position, thus helping to improve product quality and standardization.

[0003] Existing coding machines are mainly composed of the following parts: coding mechanism, folding mechanism, robotic arm, rollers or conveyor belt, etc. They are also equipped with high-precision sensors to detect the fabric position, speed and flipping status to ensure accurate folding and continuous coding. The folding mechanism acts on the inner side of the center of the fabric edge to fold it, while the coding is set on one side or the outer side of the folding mechanism.

[0004] Current coding machines suffer from the following drawbacks: Because the folding mechanism is located at the center of the fabric edge, when dealing with large areas of fabric, the fabric's sides or one side will naturally sag due to gravity during the folding process. This prevents the fabric from folding according to the predetermined path and method, ultimately leading to folding failure. This significantly limits the application effect and operational efficiency of existing coding machines when handling large areas of fabric, failing to meet the diverse coding needs of fabrics. Improvements are urgently needed to achieve stable and efficient folding operations for fabrics of different sizes. Therefore, a fabric coding machine is proposed to address these issues. Utility Model Content

[0005] To address the shortcomings of existing coding machines and solve the problem that when folding large areas of fabric using folding suction cups, the fabric's wide width and heavy weight cause it to sag on both sides due to gravity, preventing it from folding along the predetermined path and resulting in folding failure, this unstable folding situation caused by area differences limits the processing effect and efficiency of large-area fabrics and makes it difficult to meet the marking needs of various fabrics, a new fabric coding machine is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The fabric coding machine of this utility model includes a frame, on which a display controller is mounted, and a coding table for placing fabric. It also includes a coding mechanism for coding the fabric and a flipping mechanism for flipping the coded fabric. The flipping mechanism includes a needle-type suction cup acting on the corner of the fabric to fold it over, and the folding direction is along the inner ray of the corner (the optimal folding direction is along the inner center line of the corner). The coding mechanism includes a coding device acting on either inner side of the corner of the fabric.

[0007] Preferably, the coding mechanism includes a first slide rail fixedly mounted on the platform, a first slide table slidably mounted on the first slide rail, the coding device being mounted on the first slide table via a mounting base, and the coding mechanism further includes a first cylinder for driving the coding device to perform coding.

[0009] Preferably, a servo motor for driving the platform to move is fixedly mounted on the frame, and a screw is fixedly mounted on the output end of the servo motor through a coupling. A drive block that is threadedly connected to the screw is fixedly mounted on the platform.

[0010] Preferably, a fabric pressing mechanism for clamping fabric is fixedly installed on the frame. The fabric pressing mechanism includes a rotating rod, a fabric pressing rod is fixedly installed at one end of the rotating rod, and a one-way bearing is mounted on the rotating rod. The fabric pressing mechanism also includes a clamping mechanism for clamping the one-way bearing so that the fabric pressing rod can only rotate in the direction of clamping the fabric.

[0011] Preferably, the clamping mechanism includes a cylinder, a piston rod is movably disposed at the working end of the cylinder, one end of the piston rod extends to the other side of the cylinder, a pull rod is movably disposed coaxially at the middle of the piston rod, a spring is sleeved on the pull rod, one end of the pull rod is rotatably disposed with an adjusting nut for adjusting the spring compression via a threaded connection, the two ends of the spring abut against the piston rod and the adjusting nut respectively, and the clamping mechanism also includes a locking belt sleeved on a one-way bearing, the two ends of the locking belt being fixed to the pull rod and the frame respectively.

[0012] Preferably, the frame is provided with a limiting mechanism for limiting the position of the press rod. The limiting mechanism includes a magnet fixedly mounted on the frame and an iron block fixedly mounted on the rotating rod.

[0013] Preferably, a first photoelectric sensor for detecting the presence or absence of fabric is fixedly installed on the platform.

[0018] The beneficial effects of this utility model are:

[0019] This invention provides a fabric coding machine. Its unique fabric placement and clamping design offers an effective solution for the stable folding of fabrics of varying sizes. The fabric is placed at an angle on the coding table, and the clamping position of the flipping mechanism is precisely positioned at the angle. This layout ensures that whether the fabric is large or small, it can be gripped from the key angle. For large fabrics, this avoids the problem of the ends drooping after clamping due to the overall weight, thus affecting the normal folding path and method. This ensures the stability and accuracy of the fabric folding process, greatly improving the folding success rate. It effectively overcomes the folding difficulties caused by differences in fabric area in existing technologies, significantly improving the equipment's versatility and adaptability to fabrics of different sizes. It can stably and efficiently complete the folding operation of various fabrics, meeting diverse fabric coding needs. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Specific implementation examples are given below.

[0033] Please see Figures 1-8 The present invention discloses a fabric coding machine, comprising a frame 1, on which a display controller 01 is mounted, and a coding table 2 for placing fabric. A movable platform 3 is slidably mounted on the frame 1. The platform 3 is equipped with a coding mechanism 4 for coding the fabric and a flipping mechanism 5 for flipping the coded fabric. The flipping direction is along the inner ray of the corner. The coding mechanism 4 includes a movable and angle-adjustable coding device 401, which is located directly above the included angle of the fabric and the coding direction is parallel to the edge of the fabric. The flipping mechanism 5 includes a movable and angle-adjustable coding device 401. The device includes an angle-adjustable needle suction cup 501 and a first drive mechanism 51 for driving the needle suction cup 501 to grip the coded fabric. The coding mechanism 4 includes a first slide rail 402 fixedly mounted on a platform 3, a first slide table 403 slidably mounted on the first slide rail 402, and a coding device 401 mounted on the first slide table 403 via a mounting base. The coding mechanism 4 also includes a first cylinder 404 for driving the coding device 401 to perform coding. The first drive mechanism 51 includes a second slide rail 502 fixedly mounted on the platform 3, and a second slide table 503 slidably mounted on the second slide rail 502. The flipping mechanism 5 also includes a second drive mechanism 52 for flipping the fabric gripped by the needle suction cup 501. The second drive mechanism 52 includes a sleeve 17 fixedly mounted on the second slide 503. A rotating shaft 18 is rotatably mounted in the sleeve 17 via a bearing. The needle suction cup 501 is fixedly mounted at one end of the rotating shaft 18. A second cylinder 504 for driving the needle suction cup 501 to grip the fabric 15 is fixedly mounted on the platform 3. A connecting plate 19 is fixedly mounted on one side of the second slide 503. A third cylinder for driving the needle suction cup 501 to flip the fabric 15 is fixedly mounted on the connecting plate 19. Cylinder 505, the piston rod of the third cylinder 505 is movably mounted with a connecting rod 20 via a fisheye bearing, and one end of the connecting rod 20 is fixedly connected to one end of the rotating shaft 18; during operation, any included angle portion of several pieces of fabric 15 is placed on the coding table 2, the platform 3 can move up and down on the frame 1, and through the cooperation of the first slide rail 402 and the first slide table 403, the first cylinder 404 can drive the coding device 401 to perform the coding action. The operator can adjust the angle of the coding device 401 as needed so that its coding direction is parallel to the edge of the included angle of the fabric 15 and close to the top of the included angle of the fabric 15, so as to accurately code at a specific position on the fabric (e.g. Figure 5As shown, the coding device 401 can be set at different positions (coder 401a) according to different equipment assembly needs. After coding is completed, the second cylinder 504 in the flipping mechanism 5 drives the second slide table 503 to move on the second slide rail 502, so that the needle suction cup 501 approaches the appropriate position of the included angle of the fabric 15 and clamps the coded fabric 15. The second cylinder 504 drives the needle suction cup 501 to return and lift the coded fabric 15. Then, the third cylinder 505 is activated, and its piston rod drives the connecting rod 20 to swing. The connecting rod 20 drives the rotating shaft 18 to rotate, thereby driving the needle suction cup 501 to swing. At the same time, the needle suction cup 501 stops clamping the coded fabric 15 and swings the clamped fabric 15 at the included angle position for flipping (e.g. Figure 7 As shown in the figure, the arrow points to the center of the included angle within the corner of fabric 15. Any direction within the corner of fabric 15 is the ray within that corner. The optimal choice is for the needle suction cup 501 to fold along the center 21 of the ray within the corner of fabric 15 (or the folding direction can also be along the direction close to the center of the ray within the corner of fabric 15). Using the above principle, several pieces of fabric 15 are coded. The design of this invention allows for flexible adjustment of the position and angle of the coding device 401 and the needle suction cup 501. The way the included angle of fabric 15 is placed on the coding table 2 ensures that even large areas of fabric 15 can be gripped by the needle suction cup 501. When folding the fabric 15 at the angle, if the clamping position of the fabric 15 is not in the middle or on one side, the edge of the fabric will not droop naturally due to gravity. This prevents the fabric 15 from being folded according to the predetermined folding path and method, ultimately leading to folding failure. This greatly improves the adaptability and operability of different areas, especially large areas of fabric 15, ensuring that the fabric 15 can be folded stably according to the set folding path, avoiding folding failure caused by the sagging of the fabric 15. This significantly improves the versatility and operating efficiency of the equipment, meets the diverse needs of numbering fabric 15, and effectively solves the limitations of existing technology in handling large areas of fabric.

[0034] Furthermore, a servo motor 6 for driving the platform 3 is fixedly mounted on the frame 1. A screw 7 is fixedly mounted on the output end of the servo motor 6 via a coupling. A drive block 8 threadedly connected to the screw 7 is fixedly mounted on the platform 3. A second photoelectric sensor 12 for detecting the fabric thickness is fixedly mounted on the platform 3. During operation, the coding mechanism 4 and the flipping mechanism 5 must always maintain a consistent distance from the fabric 15 below. The second photoelectric sensor 12 detects the thickness of several pieces of fabric 15 on the coding platform 2 in real time and feeds the signal back to the display controller 0. The control system of 1 controls the operation of servo motor 6 based on the thickness information of several fabrics 15. The rotation of servo motor 6 drives screw 7 to rotate through coupling. Since the drive block 8 on the platform 3 is threadedly connected to screw 7, the platform 3 can move up and down, thereby accurately adjusting the height position of the platform 3. This allows the coding mechanism 4 and the flipping mechanism 5 to operate the fabric 15 better, ensuring that the needle suction cup 501 can accurately penetrate the fabric 15 to a suitable depth to achieve stable folding. At the same time, it ensures that the distance between the coding device 401 and the fabric 15 is accurately matched for high-quality coding.

[0035] Furthermore, a fabric pressing mechanism 9 for clamping fabric is fixedly installed on the frame 1. The fabric pressing mechanism 9 includes a rotating rod 901, a fabric pressing rod 902 is fixedly installed at one end of the rotating rod 901, and a one-way bearing 903 is mounted on the rotating rod 901. The fabric pressing mechanism 9 also includes a clamping mechanism 904 for clamping the one-way bearing 903 so that the fabric pressing rod 902 can only rotate in the direction of clamping fabric.

[0036] Example 1: See details Figure 4 The clamping mechanism 904 is a clamping cylinder 904a with clamping function. When several pieces of fabric 15 are placed on the coding table 2, they need to be fixed. The clamping cylinder 904a is activated to clamp the one-way bearing 903.

[0037] Example 2: See details Figure 5The clamping mechanism 904 includes a cylinder 9041. A piston rod 9042 is movably mounted on the actuating end of the cylinder 9041. One end of the piston rod 9042 extends to the other side of the cylinder 9041. A pull rod 9043 is movably mounted coaxially in the middle of the piston rod 9042. A spring 9044 is mounted on the pull rod 9043. One end of the pull rod 9043 is rotatably connected to an adjusting nut 9045 for adjusting the compression of the spring 9044 via a threaded connection. The two ends of the spring 9044 abut against the piston rod 9042 and the adjusting nut 9045, respectively. The clamping mechanism 904 also includes a locking belt 9046 mounted on a one-way bearing 903. The two ends of the locking belt 9046 are fixed to the pull rod 9041. On frame 1 and cylinder 043, during operation, spring 9044 plays a crucial auxiliary role throughout the entire workflow. When cylinder 9041 is not in operation, spring 9044 provides an additional safety mechanism for the system. It is sleeved on pull rod 9043, with one end abutting against piston rod 9042 and the other end abutting against adjusting nut 9045. Adjusting nut 9045 is threaded onto pull rod 9043. By rotating adjusting nut 9045 to change its position on pull rod 9043, the initial compression of spring 9044 can be precisely adjusted. The purpose of this is to flexibly set the elastic potential energy stored in spring 9044 in its initial state according to different working conditions and the characteristics of fabric 15, thereby adjusting the tension of spring 9044. The magnitude of the reverse tension applied by rod 9043 ensures that the locking belt 9046 maintains a certain degree of tension. Even when cylinder 9041 is not in operation, the locking belt 9046 still exerts a corresponding frictional force on the one-way bearing 903. This prevents the one-way bearing 903 from rotating unexpectedly due to slight equipment shaking or minor external forces during normal operation, thus avoiding the loosening of the fabric pressing rod 902. This ensures that the fabric 15 is in a relatively stable, ready-to-operate state beforehand. When entering the normal operation phase, after starting cylinder 9041, the actuating end of cylinder 9041 drives piston rod 9042 to move. The displacement of piston rod 9042 pulls rod 9043. During this process, the compression state of spring 9044 will... Based on the dynamic changes in the movement range of the piston sleeve 9042, the locking belt 9046, pulled by the pull rod 9043, tightly locks the one-way bearing 903, strictly limiting its rotation direction. This ensures that the rotating rod 901 can only rotate in one direction towards the fabric 15. Even when encountering external interference, such as vibrations generated by the equipment itself during the coding process, disturbances caused by airflow in the workshop environment, or pulling forces during the subsequent folding process of the fabric 15, the pressure rod 902 will always maintain the state of pressing the fabric 15 firmly because the one-way bearing 903 has been reliably locked by the locking belt 9046, limiting the reverse rotation path. It will not rotate in the opposite direction to loosen the fabric 15 due to external forces, thus steadily clamping and fixing the fabric 15 on the coding table 2.Especially when handling large areas of fabric 15, which has a large mass and inertia, conventional clamping methods are prone to shaking and displacement during operation. This clamping mechanism, with its unique design, effectively overcomes these problems, preventing issues such as uneven fabric folding and positional shifts. It ensures that coding, folding, and other operations can be carried out smoothly and precisely, significantly improving overall work quality and operational accuracy.

[0038] Furthermore, the frame 1 is provided with a limiting mechanism 10 for restricting the position of the pressing rod 902. The limiting mechanism 10 includes a magnet 1001 fixedly mounted on the frame 1 and an iron block 1002 fixedly mounted on the rotating rod 901. During operation, when it is necessary to place uncoded fabric 15, the pressing rod 902 rotates to the open position. At this time, the iron block 1002 on the rotating rod 901 approaches the magnet 1001 on the frame 1. The magnet 1001 attracts the iron block 1002, thereby fixing the pressing rod 902 in the position. The open position allows staff to easily place the uncoded fabric 15 on the coding table 2, preventing the pressure rod 902 from shaking and affecting the placement of the fabric 15. After the fabric 15 is placed, the pressure rod 902 is rotated to disengage the iron block 1002 from the magnet 1001, and then rotated to the subsequent pressing position. This provides convenience for staff to place the uncoded fabric 15, improves the efficiency of the preparatory work for the entire fabric 15 coding operation, and ensures that subsequent coding and folding operations can be carried out smoothly and efficiently.

[0039] Furthermore, a first photoelectric sensor 11 for detecting the presence or absence of fabric is fixedly installed on the platform 3. During operation, the first photoelectric sensor 11 emits light and receives reflected light. When fabric 15 is placed on the platform 3, the light reflection changes, and the first photoelectric sensor 11 transmits the signal to the control system of the display controller 01. The control system determines whether fabric 15 exists and decides whether to start subsequent coding and other operations. This can effectively avoid the equipment running idle or operating incorrectly due to misjudgment. At the same time, the equipment can automatically stop when no fabric 15 is detected.

[0040] Furthermore, a protective partition 13 is fixedly mounted on the platform 3 around the coding mechanism 4 and the flipping mechanism 5. During operation, the protective partition 13 isolates the coding mechanism 4 and the flipping mechanism 5 from the external environment, preventing operators from accidentally contacting the moving parts. The protective partition 13 can effectively ensure the safety and cleanliness of the operating environment, improve the safety of the equipment, protect operators from mechanical injury, and is conducive to the long-term stable operation of the equipment and the improvement of product quality.

[0041] Furthermore, an array of rubber feet 14 are equidistantly mounted on the bottom of the frame 1. During operation, the rubber feet 14 are installed at the bottom of the frame 1 and in contact with the ground, serving as a buffer and shock absorber to absorb the vibration generated during equipment operation. When processing the fabric 15, the equipment may experience significant vibration due to the weight of the fabric 15 and the operating force. The rubber feet 14 can effectively alleviate this vibration, reduce the transmission of equipment vibration to the ground, reduce equipment operating noise, and prevent internal parts from becoming loose or damaged due to excessive vibration. This extends the service life of the equipment, improves the stability and reliability of equipment operation, and reduces work interruptions and maintenance costs caused by equipment malfunctions.

[0042] In this invention, damping buffers 16 are provided near the end of the stroke of the first cylinder 404, the second cylinder 504, and the third cylinder 505. The damping medium consumes the kinetic energy of the cylinder, avoids rigid collisions, reduces impact vibration, reduces the risk of fatigue damage to components, extends the life of the equipment, reduces noise, provides controllable deceleration, and makes the movement more stable.
