Description
Technical Field
[0001] The present invention relates to the technical field of winders, and in particular to an automatic winder. Background Art
[0002] An automatic winder is an automated device used to wind continuous materials such as film, paper, metal foil, cable, ribbon, etc. in an orderly manner according to a set length or weight. It is widely used in packaging, electronics, textiles, printing, metallurgy and other industries. Its main function is to wind the strip material that has passed the production process evenly and neatly onto a reel or core for subsequent storage, transportation and use.
[0003] However, in practice, there are still some problems: 1. In the prior art, a core drum structure is commonly used for winding strip-shaped, tubular, or linear plastic products, such as drip irrigation tape, drip irrigation pipe, PP, and PE pipes. However, such equipment typically relies on manual loading and unloading of the core drum during operation. After each finished roll, the operator must manually remove the fully loaded core drum and reload the empty core drum into the winding mechanism. This process is repetitive, labor-intensive, and prone to fatigue. Furthermore, in high-speed continuous production environments, manual loading and unloading of the core drum becomes a key bottleneck affecting overall winding efficiency. If the operator fails to react promptly or the operating speed cannot keep up with the material delivery rhythm, winding interruptions, finished product accumulation, and even equipment failure can occur. 2. In traditional winding equipment, the common structure lacks the ability to dynamically adjust material tension and is not equipped with a synchronous wire arrangement mechanism or intelligent guiding device. As a result, the finished product is prone to various quality problems during the winding process. This is especially true when winding linear or flexible materials such as drip irrigation tape, drip irrigation pipe, or PP, PE plastic pipe. Because the material itself is soft and easily deformed, improper tension control or inaccurate guidance will lead to uneven tightness between winding layers, end misalignment, wrinkles and bubbles, etc., which not only affects the neatness of the coiled material appearance, but may also cause problems such as loose coils and jams during transportation or subsequent processing. In addition, improper installation of the winding core drum or untimely replacement can also cause defects such as coil deviation and eccentric winding.
[0004] Therefore, it is necessary to provide a new automatic winder to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with the related art, the automatic rewinder provided by the present invention has the following beneficial effects: 1. The present invention provides an automatic rewinder. By symmetrically arranging two groups of chuck mechanisms on the switching boom and combining with a rotary cylinder to achieve alternating switching, the replacement efficiency of the core is effectively improved. After one group of chucks completes winding, the switching boom immediately rotates to transfer the wound core to the unloading station, and at the same time, places the empty core directly behind the wire arranging mechanism to start a new round of winding, forming an alternating continuous operation process, greatly improving the working beat of the whole machine. Compared with the traditional single-station winding method, this device realizes the parallel operation of the three processes of winding, unloading and loading, effectively avoiding the problem of winding interruption caused by core replacement, reducing the downtime, and improving the winding output per unit time. In addition, through the cooperation of the cylinder and the inner supporting claws, the chuck mechanism ensures the stable clamping of the core, avoiding slipping or jumping during the winding process, and ensuring the uniform consistency of the winding quality, which is especially suitable for long-term continuous working scenarios in medium and high-speed production environments; 2. By setting a metering wire arranging mechanism on the whole machine frame and combining the combined arrangement of guide wheels and metering wheels, not only can the length of the material tape be accurately controlled, but also the wire arranging position can be dynamically adjusted, so that the winding is tighter and more uniform. The metering wheel is connected to a proximity switch. Combining with the target meterage set by the control system, the length of each winding can be accurately controlled to meet the customized requirements of different production processes for the material length, effectively reducing the waste rate caused by length errors. At the same time, the linear sliding module drives the guide wheel frame to move left and right, so that the material tape is wound around the core in layers tightly, avoiding poor appearance or wrinkling of the finished product caused by local accumulation or overlap. In addition, the rim of the guide wheel is higher than the metering wheel, forming a guide for the upper and lower paths of the material tape, making the running tension of the material tape more stable and the path more clear, helping to maintain the tension of the material tape, effectively preventing deviation and tape skipping phenomena, and ensuring the cleanliness of the wound finished product and the consistency of the coil appearance.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0020] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.
[0021] Please refer to Figures 1 to 9 , an automatic winding machine provided by an embodiment of the present invention, the automatic winding machine includes: An integral frame ①, and a control cabinet ② installed on the integral frame ①; A three-axis truss ⑦, erected above the integral frame ①, the three-axis truss ⑦ includes an X-axis moving module ⑦① erected on the integral frame ①, a Z-axis moving module ⑦② is provided on the X-axis moving module ⑦①, and a Y-axis moving module ⑦③ is provided on the Z-axis moving module ⑦②; The metering wire arranging mechanism ③ includes a linear sliding module ③①, a guide wheel frame ③② is fixedly installed on the sliding execution end of the linear sliding module ③①, a metering wheel ③③ is rotatably installed in the middle of the guide wheel frame ③②, guide wheels ③④ are rotatably installed on both sides of the guide wheel frame ③② where the metering wheel ③③ is located, a metering proximity switch ③⑤ for the passive metering wheel ③③ is installed on the guide wheel frame ③②, and the metering proximity switch ③⑤ is electrically connected to the control cabinet ②; There are two sets of chuck mechanisms 5. The two sets of chuck mechanisms 5 for automatically clamping the core for winding are symmetrically installed in the winding grooves 401 on both sides of the switching boom 4. The chuck mechanism 5 includes a fixed chuck 51 and a clamping and opening chuck 52 respectively installed on both sides of the winding groove 401. The fixed chuck 51 includes a winding motor 511. The winding motor 511 is embedded in the side wall of one side of the winding groove 401, and a first chuck 512 is fixedly sleeved on the output shaft of the winding motor 511. The clamping and opening chuck 52 includes a cylinder 521 fixedly installed on the other side of the winding groove 401. A support plate 522 is fixedly installed at the telescopic end of the cylinder 521. A connecting rod 523 is rotatably installed on the support plate 522 through a bearing. A second chuck 524 is fixedly installed at one end of the connecting rod 523 facing the first chuck 512. The cylinder 521 and the winding motor 511 are electrically connected to the control cabinet 2; There are two sets of cutting and winding mechanisms 6. The two sets of cutting and winding mechanisms 6 are respectively installed at the upper and lower ends of the switching boom 4 and are located in the middle of the two sets of chuck mechanisms 5; The mechanical claw 8. The mechanical claw 8 for loading and unloading is installed at the vertical downward execution end of the Y-axis moving module 73.
[0022] It should be noted that: during use, the control cabinet 2 is used to control the three-axis truss 7 to drive the mechanical claw 8 to clamp and place the core cylinder into the winding groove 401 and between the first chuck 512 and the second chuck 524. Then, the cylinder 521 is driven to push the support plate 522 to drive the second chuck 524 to move towards the first chuck 512 until the core cylinder is clamped and fixed on the chuck mechanism 5. Then, the winding motor 511 of the chuck mechanism 5 of the steering and metering wire arranging mechanism 3 is controlled to drive the core cylinder to rotate, so that the metering wire arranging mechanism 3 conveys the tape to the core cylinder for automatic winding.

[0023] In the embodiment of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6, the metering wire arranging mechanism 3 includes a linear sliding module 31. A guide wheel frame 32 is fixedly installed on the sliding execution end of the linear sliding module 31. A metering wheel 33 is rotatably installed in the middle of the guide wheel frame 32. Guide wheels 34 are rotatably installed on both sides of the guide wheel frame 32 where the metering wheel 33 is located. A metering proximity switch 35 for the passive metering wheel 33 is installed on the guide wheel frame 32. The metering proximity switch 35 is electrically connected to the control cabinet 2; Among them, the bottom rims of the two guide wheels 34 are both higher than the metering wheel 33.
[0024] It should be noted that when the metering wire arranging mechanism 3 is in use, the conveyed tape is passed through the guide wheels 34, the metering wheel 33, and the guide wheels 34 in sequence and is distributed alternately up and down. Driven by an external electronic ruler, the tape is tensioned and conveyed, so that the number of rotations of the metering wheel 33 is used to let the metering proximity switch 35 count the number of rotations to measure the number of meters of the wound tape, so as to realize metering and winding to the set number of meters. When metering, the linear sliding module 31 is used to drive the guide wheel frame 32 to move left and right, so that the tape is wound more evenly on the core cylinder.
[0025] In the embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 5 , inner support claws 53 are fixedly installed in the middle of the opposite sides of the first chuck 512 and the second chuck 524; It should be noted that: when the core cylinder is placed between the first chuck 512 and the second chuck 524, during the disk assembly, the inner support claws 53 are used to further clamp the core cylinder, which is convenient for more stably driving the core cylinder to wind.
[0026] Among them, insertion rods 525 are symmetrically installed on the support plate 522. The insertion rods 525 are movably inserted into the through holes opened in the switching boom 4. In this way, when the support plate 522 moves, the insertion rods 525 are used to assist the movement synchronously, making the movement of the support plate 522 more stable.
[0027] In the embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7, the cutting and winding mechanism 6 includes a mounting base 61 which is fixedly installed on the switching boom 4. A chute 601 is formed in the vertical plate of the mounting base 61. A screw rod 62 is rotatably installed in the chute 601. A slider 63 is threadedly installed on the screw rod 62. The slider 63 is slidably engaged with the chute 601. A cross bar 64 is fixedly installed on the slider 63. A tool holder 65 is slidably installed on the cross bar 64. An installation groove 69 is formed in the tool holder 65. A cutting knife 66 is vertically slidably connected to the inner wall of the installation groove 69. Locking holes 68 are formed on both side walls of the cutting knife 66. Locking spring rods 67 are fixedly connected to both sides of the inner wall of the installation groove 69. One end of the locking spring rod 67 matches the aperture of the locking hole 68; It should be noted that when the cutting and winding mechanism 6 is in use, when the switching boom 4 is flipped, when the strip is moved left and right on the cross bar 64 and is pulled to the cutting knife 66, the wound strip is cut. The cutting knife 66 can slide on the cross bar 64 through the tool holder 65, so as to adjust the left and right positions of the cutting knife 66 according to the winding position of the strip. Then, the screw rod 62 is rotated to drive the slider 63 to slide up and down along the chute 601, driving the cross bar 64 to move up and down, so as to adjust the height of the cutting knife 66, so that the cutting knife 66 can smoothly cut the strip. When it is necessary to cut the wire on the core, the control cabinet 2 controls the screw rod 62 to rotate, so as to drive the slider 63 threadedly installed thereon to move up and down along the chute 601, driving the cross bar 64 fixed on the slider 63 to move up and down, and then driving the tool holder 65 slidably installed on the cross bar 64 to drive the cutting knife 66 to complete the cutting action. To achieve the quick disassembly and assembly of the cutting knife 66, an installation groove 69 is formed in the tool holder 65. The cutting knife 66 is vertically inserted into the installation groove 69 and forms a sliding fit with the inner wall of the installation groove 69. Locking holes 68 for positioning are formed on both side walls of the cutting knife 66. Locking spring rods 67 are respectively fixedly connected to both inner walls of the installation groove 69. When the cutting knife 66 is inserted into the installation groove 69 in place, the locking spring rod 67 automatically pops into the corresponding locking hole 68 to realize the clamping and positioning of the cutting knife 66. When it is necessary to replace the cutting knife 66, only need to manually or with a tool press the locking spring rods 67 on both sides inward to make them withdraw from the locking holes 68, and then the cutting knife 66 can be pulled out vertically, which is convenient for quickly replacing the tool, improving the maintenance efficiency, and avoiding the problems of cumbersome replacement or inaccurate positioning caused by traditional installation methods such as screws; In this embodiment: a limiting groove 602 for restricting the rotation of the tool holder 65 is formed at the bottom end of the cross bar 64. The tool holder 65 is provided with a protrusion slidably engaged with the limiting groove 602, and a screw for locking is provided on the tool holder 65. In this way, after the tool holder 65 slides along the limiting groove 602 to adjust the left and right positions, the tool holder 65 can be fixed by screwing the screw.
[0028] In the embodiment of the present invention, please refer to Figure 1 、 Figure 2 、Figure 3 and Figure 8 The mechanical claw 8 includes a connecting frame 81. The connecting frame 81 is fixedly connected to the execution end vertically downward of the Y-axis moving module 73. The bottom end of the connecting frame 81 is symmetrically hinged with clamping arms 82. An electric rod 83 is fixedly installed on the connecting frame 81. The telescopic end of the electric rod 83 is fixedly installed with a transmission rod 84. The bottom end of the transmission rod 84 is fixedly installed with a connecting block 85. The connecting block 85 is symmetrically hinged with connecting rods 86. One end of the connecting rod 86 away from the connecting block 85 is hinged with the clamping arm 82. The electric rod 83 is electrically connected to the control cabinet 2; Wherein, a small clamping claw 87 for clamping the core is fixedly installed at the bottom end of the clamping arm 82.
[0029] It should be noted that when the mechanical claw 8 is used, during the feeding of the core tube, the small clamping claw 87 is aligned with the winding part of the core tube, and then the electric rod 83 is controlled to contract upward, thereby pulling the transmission rod 84. When the transmission rod 84 moves upward, it synchronously drives the connecting block 85 to move upward. When moving, the two clamping arms 82 are pulled closer to each other through the connecting rod 86, so as to drive the small clamping claw 87 to clamp the core tube, completing the material clamping. After clamping and sending it to the chuck mechanism 5 for clamping, the electric rod 83 can be controlled to extend downward. When it is necessary to clamp the wound core tube, the clamping arm 82 can be used to wrap the core tube; In the embodiment of the present invention, please refer to Figure 1 and Figure 2 At the rear side of the whole machine frame 1, there is an accumulation conveyor 9 for automatic feeding of the core.
[0030] It should be noted that the accumulation conveyor 9 here is a commonly used chain-type accumulation conveyor in the prior art. The empty core tubes are placed on the chain of the accumulation conveyor 9 and continuously moved to the feeding station of the mechanical claw 8, which is convenient for the mechanical claw 8 to pick up the core tubes for feeding. The accumulation conveyor 9 locates the position of the core tubes through infrared sensors to achieve accumulation and conveying. The specific working principle will not be described in detail here.
[0031] The working principle of the automatic winding machine provided by the present invention is as follows: During use, the control cabinet 2 is utilized to control the three-axis truss 7 to drive the mechanical claw 8 to clamp and place the core cylinder into the winding groove 401 and position it between the first chuck 512 and the second chuck 524. The driving cylinder 521 pushes the support plate 522 to drive the second chuck 524 to move towards the first chuck 512 until the core cylinder is clamped and fixed on the chuck mechanism 5. Then, the winding motor 511 of the chuck mechanism 5 of the steering and metering wire arranging mechanism 3 is controlled to drive the core cylinder to rotate, so that the wire arranging mechanism 3 conveys the strip material to the core cylinder for automatic winding. After winding to the set number of meters, the boom shaft group 41 drives the switching boom 4 to rotate 180°, rotates the unwound core cylinder to the rear of the metering wire arranging mechanism 3, and rotates the wound core cylinder to the unwinding position. When flipping, the wound strip material is automatically cut by the cutting and winding mechanism 6 and wound onto the unwound core cylinder. Then, the winding motor 511 of the chuck mechanism 5 at this position is started for winding. After winding, it flips and cycles for loading and winding. The core cylinder rotated to the unwinding position is unloaded by the mechanical claw 8 driven by the three-axis truss 7, thus realizing automatic loading and unloading and winding, with high winding efficiency, time-saving and labor-saving winding; When the metering wire arranging mechanism 3 is further in use, the conveyed strip material passes through the guide wheels 34, the metering wheel 33, and the guide wheels 34 in sequence and is distributed alternately up and down. Thus, the metering wheel 33 tensions and conveys the strip material under the drive of the servo motor 35, and the number of rotation turns of the servo motor 35 is used to measure the number of meters of the wound strip material, so as to realize metering and winding to the set number of meters. During metering, the linear sliding module 31 is used to drive the guide wheel frame 32 to move left and right, so that the strip material is wound more evenly on the core cylinder.

[0033] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention.
