[0036] A yarn padding column 310 is provided on the yarn guide base 36, and the yarn padding column 310 and the cylinder C37 are arranged in coordination.

[0037] The translation device 2 includes a lateral movement device and a vertical movement device. The lateral movement device includes a motor C21, a slide rail base 22, a slide rail assembly A23, a screw assembly A24 and a fixed block A25. The slide rail base 22 is provided with a slide rail assembly A23. One end of the motor C21 is provided with a screw assembly A24. The screw assembly A24 is provided with a fixed block A25. The fixed block A25 is provided with a vertical movement device. The vertical movement device includes a vertical movement frame 26, a slide rail assembly B27, a screw assembly B28, a motor D29 and a fixed block B210. One end of the motor D29 is provided with a screw assembly B28. The screw assembly B28 is provided with a fixed block B210. The fixed block B210 is provided with a joint device 3.

[0038] The creel 1 includes a creel main body 11, on which are provided a plurality of bobbin yarn storage devices 12, a plurality of tail yarn storage devices 13 and a plurality of yarn storage devices 14, and a tail yarn storage device 13 is coordinated with a yarn storage device 14 and a creel yarn storage device 12, and two creel yarn storage devices 12, two tail yarn storage devices 13 and two yarn storage devices 14 constitute a yarn supply system.

[0039] The bobbin storage device 12 includes a motor base 121, on which a motor A123 is mounted. One end of the motor A123 is provided with a storage shaft 122. The front end of the storage shaft 122 has a bell mouth, which is magnetic and is used to dock with the tail end of the bobbin to store the bobbin in place and secure it.

[0040] The tail yarn storage device 13 includes a tail yarn storage base 131 and a motor B132. The tail yarn storage base 131 is provided with a coil 133. One end of the motor B132 is provided with a tail yarn storage shaft 134. The coil 133 and the tail yarn storage shaft 134 form an electromagnet for adsorbing the tail yarn tube.

[0041] The yarn storage device 14 comprises a yarn storage base 141 , and a plurality of yarn storage rollers 142 are respectively provided on both sides of the yarn storage base 141 .

[0042] The specific working steps of this device are as follows:

[0043] Two bobbin yarn storage devices 12, two tail yarn storage devices 13 and two yarn storage devices 14 constitute a yarn feeding system. The yarn feeding system (such as Figure 9 ).

[0044] The translation device 2 is installed on the yarn frame 1 and is used to drive the joint device 3 to move it to a specified position. The bobbin used for the bobbin is a bobbin that can be separated into a front bobbin and a tail bobbin (such as Figure 10 ).

[0045] Preparation of bobbin yarn: The bobbin yarn is grabbed by the robot and first aligned with the tail yarn storage device 13. After the tail yarn storage device 13 senses the presence of bobbin yarn, the coil 133 is energized to separate the front bobbin tube and the tail yarn tube of the front bobbin, and the tail yarn tube is adsorbed on the tail yarn storage device 13. The robot then moves the bobbin yarn to the bobbin yarn storage device 12. The front end of the storage shaft 122 on the bobbin yarn storage device 12 is a bell mouth, and the guide shaft at the tail end of the bobbin yarn can be easily inserted into the bell mouth. Since the bell mouth is magnetic, the bobbin yarn will be adsorbed on the bobbin yarn storage device 12. The state at this time is as shown in the figure, and one end of the tail yarn is located between the tail yarn tube and the bobbin yarn. The three storage rollers 142 and the two storage rollers 142 of the yarn storage device 14 are located on both sides of the tail yarn (such as Figure 11 ).

[0046] Then the three yarn storage rollers 142 of the yarn storage device 14 move to the other side to pull the tail yarn. After the three yarn storage rollers 142 are in place, the other two yarn storage rollers 142 move to the other side, and at the same time the motor B132 rotates to release the tail yarn, thereby realizing the storage of the tail yarn. Figure 12 shown.

[0047] Tail yarn splicing: When the spare bobbin is in place and the preparations are complete, the tail yarn splicing process can be carried out. At this time, the translation device 2 moves the splicing device 3 to the designated position. The cylinder A32 pushes the splicing device 3 to the working position, and the motor (not shown) drives the suction nozzle 38 to the spare bobbin side as shown in the figure. The tail yarn guide rod 39 is rotated to the working bobbin side (as shown in the figure) by the motor. Figure 13 ).

[0048] After the joint device 3 is in place, the spare bobbin is rotated by the motor A123 on the bobbin storage device 12, and the suction nozzle 38 starts to work. When the thread end on the spare bobbin is sucked by the suction nozzle 38, the suction nozzle 38 rotates to pull the thread end out, as shown in the figure. At the same time, after the tail yarn guide rod 39 grabs the tail yarn, the motor B132 starts to rotate to release the tail yarn, and at the same time, the tail yarn guide rod 39 rotates to the position shown in the figure, pulling the tail yarn out (as shown in the figure). Figure 14 ).

[0049] Looking down from the top, the yarn tail section A of the working cylinder is directly below the cylinder C37, while the yarn tail section B of the working cylinder is located outside the cylinder C37. Figure 15 shown.

[0050] At this time, the cylinder C37 is in motion, and the motor B132 rotates to release the tail yarn, pressing the tail yarn segment A of the working cylinder yarn to the two yarn pads 310 on the yarn guide base 36. Figure 16 shown.

[0051] At this time, the tail yarn segment A of the working cylinder and the head yarn segment of the standby cylinder are in parallel and located in front of the splicer 35. The cylinder B34 pushes the splicer 35 to the specified position, and the tail yarn segment A of the working cylinder and the standby cylinder yarn enter the twisting interface of the splicer 35, and the splicing work is carried out so that the tail yarn segment A of the working cylinder and the standby cylinder yarn are twisted together to complete the tail yarn splicing work.

[0052] If the yarn splicing fails and the working cylinder yarn tail segment A is disconnected, the working cylinder yarn tail segment B still exists, allowing the splicing process to continue. At this point, the splicer 35 retracts from its operating position, and the cylinder C37 returns to its original position. The reserve cylinder yarn head segment continues to be extracted according to the process. However, the working cylinder yarn tail segment A, having already failed, cannot be spliced. However, the tail yarn guide rod still holds the working cylinder yarn tail segment B, allowing this segment to be used for splicing. The cylinder (not shown) then retracts the tail yarn guide rod 39 inward (i.e., perpendicular to the drawing), moving the working cylinder yarn tail segment B below the cylinder C37. Cylinder C37 operates to press the working cylinder yarn tail segment B against the two yarn pads 310 on the yarn guide base 36. At this point, the working cylinder yarn tail segment B and the reserve cylinder yarn head segment are parallel and located in front of the splicer 35. The cylinder B34 pushes the splicer 35 to the specified position, and the yarn tail segment B of the working cylinder and the yarn of the spare cylinder enter the splicer 35 twisting interface, and the splicing work is performed to make the yarn tail segment B of the working cylinder and the yarn of the spare cylinder twisted together, completing the yarn tail splicing work (such as Figure 17 ).

[0053] When the yarn splicing fails again and the tail yarn segment B of the working cylinder has been disconnected, the yarn storage device 14 stores a certain length of tail yarn, so the splicing work can be continued. At this time, the splicer 35 withdraws from the working position and the tail yarn guide rod 39 is pushed outward (i.e. perpendicular to the paper surface). The head segment of the spare cylinder yarn is still extracted according to the process. Since the cylinder C37 has not retreated at this time, there is a tail yarn segment C of the working cylinder yarn. The tail yarn guide rod 39 rotates to the position shown in the figure to extract the tail yarn segment C of the working cylinder yarn as the tail yarn segment for splicing. At this time, the cylinder C37 retreats to its original position (as shown in the figure). Figure 18 ).

[0054] Then, the tail yarn guide rod 39 is rotated and the two yarn storage rollers 142 are moved simultaneously to release the yarn in the yarn storage device. Figure 19 shown.

[0055] At this point, an air cylinder (not shown) retracts the tail yarn guide rod 39 inward (i.e., perpendicular to the drawing), moving the tail yarn segment C of the working cylinder below the air cylinder C37. Air cylinder C37 presses the tail yarn segment C of the working cylinder onto the two yarn pads 310 on the yarn guide base 36. The tail yarn segment C of the working cylinder and the beginning of the reserve yarn segment are now parallel and positioned in front of the splicer 35. Air cylinder B pushes the splicer 35 to the designated position, and the tail yarn segment C of the working cylinder and the reserve yarn segment enter the splicer 35 interface. The splicing operation then proceeds, splicing the tail yarn segment C and the reserve yarn segment together, completing the yarn splicing process. If splicing fails again, the above process can be repeated until the yarn in the yarn storage device is exhausted.

[0056] The above implementation scheme fully considers the situation of joint failure and realizes re-joining after multiple joint failures.

[0057] The above description is not a limitation of the design of the present invention, and the design of the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the design of the present invention also fall within the scope of protection of the design of the present invention.
