[0048] A second yarn baffle 44 is provided on the left side of the input end of the first yarn storage conveyor belt 38 on the left, and a second yarn baffle 44 is also provided on the right side of the input end of the first yarn storage conveyor belt 38 on the right.

[0049] The usage process of the device in this embodiment will be described as follows: The completed yarn packages are hung on the yarn cage 13, with the yarn axis aligned in the left-right direction. A first drive motor drives the yarn packages to move at a constant speed in the left-right direction. Initially, the L-shaped support arms 24 of the first yarn package support 19 are arranged in the front-back direction. A second drive motor 22 drives the first yarn package support 19 to rise. During the rise, a third drive motor drives the first yarn package support 19 to rotate 90° and continue rising. The first yarn package support 19 can hold the yarn package from the opening of the yarn cage 13 and extend into the yarn hanging cavity 15. At this point, the rise stops and pauses for a period of time. During this pause, as the yarn cage 13 continues to move, the first yarn package support 19 moves the yarn package out of the yarn hanging cavity 15. Then, the first yarn bobbin holder 19 is driven to descend by the second drive motor 22. During the descent, the first yarn bobbin holder is driven to rotate 90° by the third drive motor to return to the initial state and continue to descend. The first yarn bobbin holder 19 can pass through the notch on the first unloading plate 25 and place the yarn bobbin on the first unloading plate 25. The yarn bobbin can roll along the first unloading plate 25 into the yarn conveyor belt 4. The yarn conveyor belt 4 transports the yarn bobbin to the carriage structure 27.

[0050] In its initial state, the second yarn package support 35 is located below the slide structure 27, and the two L-shaped support arms 24 of the second yarn package support 35 correspond one-to-one with the two notches on the slide structure 27. The second yarn package support 35 is driven to rise by the fourth drive motor 37. During the rising process, the two L-shaped support arms 24 of the second yarn package support 35 pass through the corresponding notches on the slide structure 27 and support the yarn package as it rises. After rising to a height exceeding the second unloading plate 42, it pauses for a period of time. During the pause, the first cylinder 41 drives the second unloading plate 42 to move from its initial position to below the second yarn package support 35. Afterward, the fourth drive motor 37 drives the second yarn package support 35 to descend. During the descent, the second yarn package support 35 can pass through the notches on the second unloading plate 42 and place the yarn package on the second unloading plate 42. The second yarn package support 35 then descends to its initial state. Then, the second cylinder 43 drives the second unloading plate 42 to rotate to the left and tilt, so that the yarn can roll along the second unloading plate 42 onto the left first yarn storage conveyor belt 38. After that, the second cylinder 43 drives the second unloading plate 42 to rotate back to the center, while the first cylinder 41 drives the second unloading plate 42 back to the initial position, and the left first yarn storage conveyor belt 38 conveys the yarn forward for packaging.

[0051] When the yarn is transported again, the second cylinder 43 will drive the second unloading plate 42 to rotate to the right, so that the yarn rolls onto the first yarn storage conveyor belt 38 on the right side, and this process is repeated alternately.

[0052] Example 2 A preferred embodiment of this utility model provides a cross-floor yarn transfer device. The difference between this device and the device in Embodiment 1 is the setting of the upper floor. In this embodiment, a second yarn storage device is installed on the upper floor.

[0053] The second yarn storage device includes a second yarn storage conveyor belt, which includes a support frame, a conveyor belt, a drive motor, etc. For details, please refer to the existing technology, which will not be repeated here.

[0054] A third unloading plate is slidably provided on the side of the input end of the second yarn storage conveyor belt along the length of the second yarn storage conveyor belt. A third cylinder is installed on the support of the second yarn storage conveyor belt. The free end of the third cylinder is connected to the third unloading plate. The extension and retraction of the third cylinder can drive the third unloading plate to slide back and forth. The third unloading plate is arranged at an angle and has a notch.

[0055] The usage process of the device in this embodiment will be described as follows: The fourth drive motor 37 drives the second yarn bobbin holder 35 to rise, lifting the yarn bobbin upwards. After rising to a height exceeding the third unloading plate, it pauses for a period of time. During this pause, the third cylinder drives the third unloading plate to move from its initial position to below the second yarn bobbin holder 35. Then, the fourth drive motor 37 drives the second yarn bobbin holder 35 to descend. During the descent, the second yarn bobbin holder 35 passes through a notch in the third unloading plate and places the yarn bobbin on it. The second yarn bobbin holder 35 descends to its initial state, and the yarn bobbin rolls along the third unloading plate onto the second yarn storage conveyor belt. Afterwards, the third cylinder drives the third unloading plate back to its initial position, and the second yarn storage conveyor belt forward transports the yarn bobbin for packaging. Other steps are the same as in Embodiment 1.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
