[0002] In chemical fiber production, after the winding machine completes the yarn cake winding, the full yarn cake needs to be transferred to the buffer area, and the empty paper tube is reinstalled into the winding machine's slot for the next round of winding. Traditional transfer systems suffer from low efficiency, excessive manual intervention, and the yarn cake being prone to falling off. In existing technologies, transfer equipment typically lacks flexible buffer structures and automated loading and unloading functions, leading to production interruptions or insufficient equipment utilization. Therefore, there is an urgent need for a highly efficient, automated, and stable yarn cake transfer and discharge system. Summary of the Invention

Through the coordinated operation of the spool dropper and the double-sided winding machine, combined with the rotation and lifting mechanism, it achieves efficient transfer and automated loading of the silk cake, reduces manual intervention and improves production efficiency, effectively solving the problems pointed out in the background art.
[0004] The technical solution adopted in this utility model is:
[0005] A yarn cake transfer and discharge system includes a doffing machine and winding machines located on the left and right sides of the doffing machine. Each side of the doffing machine has at least one transfer station for use with the winding machine on that side. The discharge end of the doffing machine has a left buffer frame, a left yarn cake loading mechanism, and a left yarn hanging station, as well as a right buffer frame, a right yarn cake loading mechanism, and a right yarn hanging station. The left buffer frame, left yarn cake loading mechanism, and left yarn hanging station are used in conjunction with the transfer station on the left side of the doffing machine, and the right buffer frame, right yarn cake loading mechanism, and right yarn hanging station are used in conjunction with the transfer station on the right side of the doffing machine. The doffing machine is used for... Based on the full roll signal of the winding machine, the yarn cake on the winding machine is received through the transfer station, and the empty paper tube is installed into the winding machine slot. The yarn cake of the winding machine is loaded and transferred to the corresponding buffer rack. The left and right yarn hanging stations are used to park the yarn cart to load the yarn cake. The yarn cakes placed on the left and right buffer racks are transferred to the yarn carts parked at the corresponding yarn hanging stations through the left and right yarn cake loading mechanisms, respectively. The yarn cakes on the left transfer station of the unwinding machine are transferred to the left buffer rack through the left yarn cake loading mechanism, and the yarn cakes on the right transfer station of the unwinding machine are transferred to the right buffer rack through the right yarn cake loading mechanism.
[0006] Preferably, the bottom of the drum-dropping machine is provided with a guide rail, which is used for the drum-dropping machine to move along a predetermined path.
[0007] Preferably, the bottom of both the left and right wire-hanging stations is equipped with a rotating device that drives the left and right wire-hanging stations to rotate 180° respectively.
[0008] Preferably, the rotating device is provided with protective plates around the left and right wire hanging stations, and the protective plates limit the wire carriages parked in the corresponding wire hanging stations to prevent the wire carriages from leaving the corresponding wire hanging stations when the rotating device is rotating.
[0009] Preferably, the rotating device is equipped with a lifting mechanism that drives the wire-hanging station to rise and fall.
[0010] This invention integrates automated control, dual-sided collaborative operation, and multi-functional mechanical structure rotation, lifting, and protection to achieve high efficiency, precision, and safety in yarn cake transfer. Its technological advantages significantly solve the pain points of traditional transfer systems, such as low efficiency, high dependence on manual labor, and numerous safety hazards. It is suitable for large-scale continuous production scenarios in the chemical fiber industry and has significant practical value and market competitiveness.
[0011] The beneficial effects of this utility model are:
[0012] 1. Highly efficient collaborative operation to improve production efficiency: Through the linkage design of the doffing machine and the double-sided winding machine, the system can automatically receive the yarn cake and install the empty paper tube based on the full roll signal of the winding machine, realizing the seamless connection of the winding machine. The double-sided symmetrical transfer station, buffer rack and loading mechanism work together to significantly reduce the idle time of the equipment, ensure the continuous and uninterrupted production process, and improve the overall efficiency by more than 30%.
[0013] 2. Automated transfer, reducing manual intervention: The guide rail at the bottom of the doffing machine allows the machine to move along a predetermined path. Combined with the automated operation of the yarn cake loading mechanism, the system can autonomously complete the entire process of receiving, buffering and transferring the yarn cake to the yarn cart. The operator only needs to park the yarn cart at the yarn hanging station. No intervention is required in the other steps, reducing labor costs and operational errors.
[0014] 3. The rotating and lifting mechanism enhances loading flexibility: The rotating device at the wire hanging station can drive the wire cart to rotate 180°. Combined with the lifting mechanism to adjust the height, it can achieve precise loading of the wire cake on both sides. This design optimizes space utilization and reduces the risk of damage to the wire cake due to misalignment during loading. The lifting mechanism can lift the wire cart. When lowering, the protective plate limits the wire cart. When raising, the protective plate no longer has the limiting function, and the wire cart can directly walk down from the wire hanging station.
[0015] 4. Protective structure ensures safety and stability: The protective plates around the rotating device physically limit the wire carriage, preventing it from shifting or falling off during rotation, thus ensuring operational safety. Combined with automated control, the system can avoid safety hazards caused by human error or mechanical vibration, reducing the failure rate by more than 50%.
[0016] 5. Modular design improves equipment utilization: The independently configured buffer racks, loading mechanisms and wire hanging stations on the left and right sides support the simultaneous handling of wire cake transfer tasks from multiple winding machines. The modular structure facilitates maintenance and expansion, and the number or layout of stations can be flexibly adjusted according to production needs, increasing equipment utilization by 40%.

[0026] like Figure 1As shown, a yarn cake transfer and discharge system includes a doffing machine 1 and winding machines 2 arranged on the left and right sides of the doffing machine 1. At least one transfer station 3 is provided on each of the left and right sides of the doffing machine 1 to cooperate with the winding machine 2 on that side. The discharge end of the doffing machine 1 is provided with a left buffer frame 4, a left yarn cake loading mechanism 5, and a left yarn hanging station 6, as well as a right buffer frame 7, a right yarn cake loading mechanism 8, and a right yarn hanging station 9. The left buffer frame 4, left yarn cake loading mechanism 5, and left yarn hanging station 6 are used in conjunction with the transfer station 3 on the left side of the doffing machine 1, and the right buffer frame 7, right yarn cake loading mechanism 8, and right yarn hanging station 9 are used in conjunction with the transfer station 3 on the right side of the doffing machine 1. The bobbin machine 1 is used to receive the yarn cake on the winding machine 2 through the transfer station 3 based on the full roll signal of the winding machine 2, and to install the empty paper tube into the winding machine slot, as well as to load the yarn cake of the winding machine 2 and transfer it to the corresponding buffer rack. The left yarn hanging station 6 and the right yarn hanging station 9 are used to park the yarn cart to load the yarn cake. The yarn cakes placed on the left buffer rack 4 and the right buffer rack 7 are transferred to the yarn carts parked at the corresponding yarn hanging stations through the left yarn cake loading mechanism 5 and the right yarn cake loading mechanism 8, respectively. The yarn cake on the left transfer station 3 of the bobbin machine 1 is transferred to the left buffer rack 4 through the left yarn cake loading mechanism 5, and the yarn cake on the right transfer station 3 of the bobbin machine 1 is transferred to the right buffer rack 7 through the right yarn cake loading mechanism 8.
[0027] The drum-dropping machine 1 is already existing technology and has been disclosed in some patents. Therefore, the specific structure of the drum-dropping machine will not be described in detail in this utility model.
[0028] The bottom of the drum-dropping machine 1 is provided with a guide rail 10, which is used for the drum-dropping machine 1 to move along a predetermined path.
[0029] The bottom of both the left wire-hanging station 6 and the right wire-hanging station 9 is equipped with a rotating device 11 that drives the left wire-hanging station 6 and the right wire-hanging station 9 to rotate 180° respectively.
[0030] The rotating device 11 is equipped with protective plates 12 around the left wire hanging station 6 and the right wire hanging station 9 respectively. The protective plates 12 limit the wire carriages parked in the corresponding wire hanging stations to prevent the wire carriages from leaving the corresponding wire hanging stations when the rotating device 11 is rotating.
[0031] The rotating device 11 is equipped with a lifting mechanism that drives the wire hanging station to rise and fall.
[0032] The working principle of this utility model is as follows:
[0033] 1. After the winding machine 2 winds the yarn cake, the background control system sends a signal to the unwinding machine 1. The unwinding machine 1 runs to the corresponding winding machine outlet, so that the transfer station 3 is aligned with the winding machine 2 outlet. The winding machine 2 pushes the wound yarn cakes one by one onto the unwinding machine 1.
[0034] 2. The doffing machine 1 carries the yarn cake to the corresponding buffer rack and pushes the yarn cake to the corresponding buffer rack. That is, the yarn cake on the left transfer station 3 is pushed to the left buffer rack 4, and the yarn cake on the right transfer station is pushed to the right buffer rack 7. Then the doffing machine 1 installs the empty paper tube into the corresponding winding machine slot.
[0035] 3. When the silk cakes on the buffer rack are full, the silk cake loading mechanism on the corresponding side is replaced with a cake-removing clamp to load the silk cakes one by one from the buffer rack onto the silk cart at the corresponding silk hanging station. That is, the left silk cake loading mechanism 5 transfers the silk cakes from the left buffer rack 4 to the silk cart at the left silk hanging station 6, and the right silk cake loading mechanism 8 transfers the silk cakes from the right buffer rack 7 to the silk cart at the left silk hanging station 9. When the corresponding side of the silk cart is full of silk cakes, the corresponding silk hanging station is rotated 180° by the rotating device 11, and then the other side of the silk cart is full of silk cakes by the silk cake loading mechanism on the corresponding side. At this time, the corresponding silk hanging station can be raised by the lifting mechanism so that the bottom of the wheels of the corresponding silk cart is at the same height as the protective plate 12. At this time, the silk cart can be pushed away from the corresponding silk hanging station.
[0036] 4. Push the empty silk cart onto the corresponding silk hanging station and use the silk cake loading mechanism on the corresponding side to hang the silk until all the silk cakes on the corresponding buffer rack are hung. That is, the left silk cake loading mechanism 5 transfers the silk cake from the left buffer rack 4 to the silk cart at the left silk hanging station 6, and the right silk cake loading mechanism 8 transfers the silk cake from the right buffer rack 7 to the silk cart at the left silk hanging station 9.
[0037] Rotating devices and lifting mechanisms are common mechanical structures. This utility model does not describe the rotating device 11 and lifting mechanism in detail. In this utility model, conventional rotating devices 11 and lifting mechanisms can be used.
[0038] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
