[0001] This utility model relates to textile technology, specifically to a technology that facilitates the automated removal or placement of yarn tubes on old-fashioned doffing machines. Background Technology

[0002] The later stages of spinning equipment include the processes of yarn feeding and winding, which involve continuously feeding the yarn and winding it onto the yarn bobbin. Current technology still uses the old-fashioned spinning machine (doffing machine) during spinning, and the yarn bobbins used on the old-fashioned spinning machine need to be manually removed and replaced one by one when changing them.

[0003] like Figure 1 and Figure 2 The image shows an existing, older type of doffing machine. Its main structure consists of a main frame 01, a spinning body 02, and a placement platform 03. The placement platform 03 is vertically adjustable and mounted on the main frame 01. The spinning body 02 is located at the upper end of the main frame 01. The placement platform 03 is used to place the yarn tube 04, and the spinning body 02 spins yarn onto the yarn tube 04. That is, the yarn from the spinning body 02 is wound onto the yarn tube 04 through rotation. This traditional doffing machine equipment and its working process are existing technology and will not be described in detail here.

[0004] This old-fashioned doffing machine has a significant problem in application: the process of taking away or placing the yarn tubes on the placement platform 03 requires manual operation one by one, which cannot achieve automated taking or placing, seriously affecting work efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a yarn support platform that facilitates the receiving and placement of yarn tubes.

[0006] To achieve the above objectives, this utility model provides a yarn-supporting platform for automatic doffing on a roving frame, which includes a crossbeam frame and a yarn-supporting inclined plate; the yarn-supporting inclined plate has a first support column and a second support column, and multiple yarn-supporting inclined plates are connected to the crossbeam frame, the first support column and the second support column are used to place yarn tubes; the yarn-supporting inclined plate is used to be placed on two adjacent inclined yarn tube support joints on the lower rib.

[0007] Preferably, the first and second receiving columns have a main body and a conical end, the conical end being able to mate with the hollow tube at the bottom of the yarn tube. Preferably, it further includes a transverse moving guide rail, a vertical guide column, a passive plate, and a platform positioning moving rod; a retractable platform positioning moving rod is provided on the vertical guide column; the side of the yarn-supporting platform has a passive plate; a driving plate on the lower rib can mate with the passive plate to drive the yarn-supporting platform to rise and fall along the vertical guide column; the transverse moving guide rail is used to drive the yarn-supporting platform and the vertical guide column to move laterally; the platform positioning moving rod is used to support the yarn-supporting platform. Preferably, the platform positioning moving rod is retractably mounted on the vertical guide column, and multiple platform positioning moving rods are connected to a horizontal moving rod via connecting plates; the yarn-supporting platform includes a plate body, the plate body being slidably mounted on the vertical guide column via a driving card.

[0008] The beneficial effects of this invention are as follows: After the empty yarn tubes have completed spinning, they are first clamped by the grippers located above. Then, the yarn support platform of this invention can be placed on the placement platform. The grippers place the yarn tubes onto the first and second receiving columns to receive them, and then the yarn tubes can be lifted and removed at once.

[0012] Example 1:

[0013] like Figure 1 and Figure 22 As shown, a yarn-supporting platform 40 for automatic doffing of a roving frame in this embodiment includes a crossbeam frame 41 and a yarn-supporting inclined plate 42.

[0014] The yarn support inclined plate 42 has a first support column 43 and a second support column 44. Multiple yarn support inclined plates 42 are connected to the crossbeam frame 41. The first support column 43 and the second support column 44 are used to place the yarn tube 04. The yarn support inclined plate 42 is used to place on two adjacent inclined yarn tube receiving joints 45 on the lower rib 110, such as adjacent inclined receiving joints 451 and 452.

[0015] Preferably, the first receiving post 43 and the second receiving post 44 have a main body rod portion 46 and a conical end head 47, wherein the conical end head 47 can cooperate with the hollow tube portion at the bottom of the yarn tube 04.

[0016] For older doffing machines, the yarn support platform 40 provided in this embodiment can be directly placed on the placement platform 102 of the lower rib 110 of the doffing machine. In this way, the yarn tube can be supported by the yarn support platform 40 for one-time loading and unloading, realizing an automated process and avoiding the need for personnel to handle the yarn tube individually, thereby improving work efficiency.

[0017] It should be noted that when the yarn tube needs to be picked up through the yarn support platform 40, it also needs to be completed through the following structural cooperation, which will be described in more detail below.

[0018] The specific operation process of the yarn support platform used for automatic doffing on a roving frame needs to be implemented through the process described in the following embodiments.

[0019] After the empty yarn tubes have finished spinning, they are first clamped by the grippers (e.g., using the swing claw structure described below). Then, the yarn support platform of this invention can be placed on the placement platform. The grippers place the yarn tubes onto the first and second receiving columns to receive them, and then the yarn tubes can be lifted and removed at once. Alternatively, when it is necessary to place empty yarn tubes onto the yarn tube receiving joint at once, the empty yarn tubes are first placed on the first and second receiving columns, then clamped and fixed by the grippers and removed. Finally, the grippers place the empty yarn tubes onto the placement platform at once.

[0020] Preferably, the main body 46 and the conical end 47 are connected by a threaded detachable connection. That is, the conical end 47 can be detached from the inner cavity of the main body 46 via an external thread. This method allows adjustment of the tightening depth to adjust the overall height of the main body 46 and the conical end 47 to fit the yarn tube. Furthermore, the conical portion of the conical end 47 can be of different sizes, allowing for selection of different sized conical end 47s to facilitate mating with the main body 46. This also allows for mating with the cavity at the bottom of the yarn tube as needed, thus adapting to different sizes of yarn tubes. Moreover, the threaded structure of the different sized conical end 47s is identical, ensuring they all fit with the main body 46.

[0021] Example 2:

[0022] like Figures 4 to 7As shown, this embodiment of a drag mechanism for improving the doffing method of a roving frame includes a yarn-supporting platform 40, a transverse moving guide rail 50, a vertical guide column 55, a passive plate 31, and a platform positioning and moving rod 32. A retractable platform positioning and moving rod 32 is provided on the vertical guide column 55 to support the yarn-supporting platform 40. The yarn-supporting platform 40 is vertically movably mounted on the vertical guide column 55, and the passive plate 31 is located on the side of the yarn-supporting platform 40. The transverse moving guide rail 50 is used to drive the yarn-supporting platform 40 and the vertical guide column 55 to move laterally.

[0023] In this embodiment, the dragging mechanism, via the lateral moving guide rail 55, enables the yarn-supporting platform 40 to move horizontally. This allows the yarn-supporting platform 40 to extend into the position between the lower rib 110 and the upper rib, serving to receive full yarn tubes or transfer empty yarn tubes to the upper rib. When the yarn-supporting platform 40 is in the outer position, it can exchange positions with the hanging yarn platform 90, transferring full yarn tubes to the hanging yarn platform 90, while the hanging yarn platform 90 can transfer empty yarn tubes to the yarn-supporting platform 40. Furthermore, the yarn-supporting platform 40 can move vertically using the lifting function of the lower rib 110. The yarn-supporting platform 40 also has a passive plate 31 on its side, allowing the lower rib 110 to lift the yarn-supporting platform 40 or directly lift its bottom via the passive plate 31. Additionally, the platform positioning and moving rod 32 supports the yarn-supporting platform 40, thus enabling free switching between multiple relative positions of the lower rib 110 and the yarn-supporting platform 40. The specific process is described below.

[0024] Example 3:

[0025] The lateral moving guide rails 50 are multiple in number, each including a fixed block 51, a drive gear 52, a toothed plate 53, and a moving plate 54. The fixed block 51 is disposed on the ground, and the moving plate 54 is movably disposed on the fixed block 51 via a recessed groove 56. A vertical guide post 55 is disposed on the upper outer end of the moving plate 54, and the toothed plate 53 is disposed on one side of the moving plate 54. The drive gear 52 is meshed with the toothed plate 53. The vertical guide post 55 is disposed on the upper outer end of the moving plate 54.

[0026] The driven wheel 58 is driven to rotate by the belt 61, which in turn drives the rotating rod 57 to rotate, and the rotating rod 57 drives the drive gear 52 to rotate.

[0027] In actual operation, the rotation of belt 61 drives the driven wheel 58 to rotate, which in turn drives the rotating rod 57 to rotate, thereby driving the drive gears 52 in multiple positions to rotate. The movement of the drive gears 52 causes the toothed plate 53 to drive the moving plate 54 to move horizontally. The vertical guide column 55 follows the horizontal movement, which in turn drives the yarn-supporting platform 40 to move horizontally.

[0028] The platform positioning and moving rod 32 is retractably mounted on the vertical guide column 55, and multiple positions of the platform positioning and moving rod 32 are connected to the horizontal moving rod 34 via connecting plates 33. When the cylinder structure or other telescopic structure drives the horizontal moving rod 34 to move, the connecting plate 33 causes the platform positioning and moving rod 32 to extend or retract on the vertical guide column 55, thus providing support for the vertically adjustable yarn-supporting platform 40.

[0029] The yarn-supporting platform 40 includes a plate 45, multiple yarn-supporting plates 46, and a receiving column 47. The plate 45 is slidably mounted on the vertical guide column 55 by driving the card 551. The multiple yarn-supporting plates 46 are respectively disposed at the inner end of the plate 45, and the receiving column 47 is respectively disposed in each yarn-supporting plate 46.

[0030] The vertical guide post 55 has a slidable drive card 551, which is connected to the yarn-supporting platform 40. The two sides of the drive card 551 are slidably mounted on the guide protrusions of the vertical guide post 55 by means of sliding wheels 552. This structure allows the yarn-supporting platform 40 to move vertically along the vertical guide post 55, but when the vertical guide post 55 moves horizontally, it drives the yarn-supporting platform 40 to move via the drive card 551.

[0031] The present invention provides a dragging mechanism for improving the doffing method of a roving frame. It can move horizontally, thus reaching deep into the roving frame, moving between the lower and upper rovings. The lower roving can drive the dragging platform to the required height, thereby completing the process of removing the yarn tube or placing the empty tube at different height positions, thus completing the auxiliary work of automatic doffing.

[0032] Furthermore, the dragging mechanism in this application, in conjunction with the swing claw structure 20 and the yarn-lifting platform 90, can complete the automatic yarn unloading process. The specific process is as follows:

[0033] Example 4:

[0034] like Figures 3 to 11 As shown, the present invention provides an improved doffing method roving frame, which includes a main frame 10, a swing claw structure 20, a drag mechanism 30 and a yarn lifting platform 90.

[0035] The lower end of the main frame 10 is provided with a liftable lower rib 110. The lifting system of the lower rib 110 is an inherent technology of this equipment and will not be described in detail here. The lower rib 110 is provided with a drive plate 111. The upper end of the main frame 10 is provided with an upper rib 130. The upper rib 130 is provided with N spindle wings 120. The spindle wings 120 have spindle wing rods 19.

[0036] The swing claw structure 20 is disposed on the bottom surface 131 of the upper rib 130, and the swing claw structure 20 is used to clamp and fix the yarn tube 04 on the spindle wing spindle rod 19.

[0037] The dragging mechanism 30 is located on the lower side of the main frame 10. The dragging mechanism 30 includes a yarn-supporting platform 40, a transverse moving guide rail 50, and a vertical guide column 55. The transverse moving guide rail 50 is used to drive the yarn-supporting platform 40 and the vertical guide column 55 to move laterally. The yarn-supporting platform 40 has a passive plate 31 on its side, which is preferably an L-shaped structure. The driving plate 111 can cooperate with the passive plate 31 to drive the yarn-supporting platform 40 to rise and fall along the vertical guide column 55. The vertical guide column 55 has a retractable platform positioning and moving rod 32.

[0038] The yarn-lifting platform 90 is located on the upper outer side of the main frame 10. The yarn-lifting platform 90 is used to exchange empty yarn tubes and full yarn tubes with the dragging mechanism 30. An empty yarn tube is a yarn tube without yarn, and a full yarn tube is a yarn tube that has completed spinning. The yarn-lifting platform 90 can load and place empty yarn tubes onto the dragging mechanism 30, and can also remove full yarn tubes from the dragging mechanism 30.

[0039] Preferably, Figure 11 In this design, the top of the yarn-lifting platform 90 is connected to the bottom of the main frame 10 via a lifting rope 91. The side of the yarn-lifting platform 90 is slidably mounted in the sliding groove 101 of the main frame 10 via guide pulleys 92. The yarn-lifting platform 90 has a rotating wheel 93, empty spindles 94, and a spindle drive steel belt 95. The spindle drive steel belt 95 is sleeved on the rotating wheel 93, and multiple sets of empty spindles 94 are arranged on the spindle drive steel belt 95. The rotation of the rotating wheel 93 causes the spindle drive steel belt 95 to move, thus rotating the empty spindles 94. Each empty spindle 94 acts as a gripper to hold and fix a yarn tube. The lifting action of the lifting rope 91 allows the yarn-lifting platform 90 to lower the empty spindles 94 to the position of the yarn-dragging platform 40, thus completing the action of grabbing and removing full yarn tubes, as well as placing empty yarn tubes. The lifting rope 91 can also be a lifting rod, which uses existing technology and will not be described in detail here.

[0040] like Figures 12 to 21 As shown, the process of the device in this embodiment in a specific application is as follows:

[0041] After the yarn is fully spun, the following actions are performed:

[0042] Step 1: The lower rib 110 drives the full yarn (full yarn tube state) to rise to the yarn grabbing position, and the swing claw structure 20 extends to grab the yarn;

[0043] Step 2: The lower rib 110 descends to the mounting position; in the height direction, the lower rib 110 stops at several positions from bottom to top: super-lower position, mounting position, middle support position, middle pin position, and yarn grabbing position (yarn picking position). The super-lower position is the lowest position where the lower rib 110 descends. The mounting position is the position where the driving plate 111 of the lower rib 110 drives the passive plate 31 on the side of the yarn support platform 40 to rise. The middle support position is a position where the lower rib 110 temporarily stops. The middle pin position refers to the position where the platform positioning and moving rod 32 supports the yarn support platform 40.

[0044] Step 3: The drag mechanism 30 moves from the spinning position to the doffing position; the driving plate 111 and the passive plate 31 of the lower rib 110 overlap vertically;

[0045] Step 4: The lower rib 110 drives the yarn support platform 40 to rise to the middle pin position, and the platform positioning moving rod 32 extends;

[0046] Step 5: The lower rib 110 descends to the middle drag position, the passive plate of the yarn support platform 40 separates from the driving plate of the lower rib 110, the dragging mechanism 30 moves forward from the yarn dropping position to the yarn changing position, and the yarn support platform 40 moves away from directly below the lower rib 110.

[0047] Step 6: The lower rib 110 descends to the over-descent position, below the yarn support platform 40, and the dragging mechanism 30 moves to the yarn drop position, with the yarn support platform 40 positioned above the lower rib 110;

[0048] Step 7: The lower rib 110 pushes the yarn support platform 40 up to the yarn picking position, the swing claw structure 20 retracts, and the full yarn is placed on the yarn support platform 40;

[0049] Step 8: The dragging mechanism 30 follows the lower rib 110 down to the over-drop position, the doffing platform 40 separates from the lower rib 110, and the dragging mechanism 30 moves forward from the doffing position to the yarn changing position;

[0050] Step 9: The yarn hoisting platform 90 descends, the empty spindle 91 on the yarn hoisting platform 90 grabs the full yarn tube on the drag mechanism 30, the yarn hoisting platform 90 lifts the full yarn on the yarn support platform 40 and rises to a certain height, the spindle drive steel belt 92 inside the yarn hoisting platform 90 rotates one spindle distance, so that the empty yarn tube on the yarn hoisting platform 90 is aligned with the receiving column on the yarn support platform 40, the yarn hoisting platform 90 descends, places the empty yarn tube on the yarn hoisting platform 90 on the yarn support platform 40, and the yarn hoisting platform 90 rises back to its original position;

[0051] Step 10: Drag the platform 40 to the doffing position, the lower rib 110 rises to the tube grabbing position, and the swing claw structure 20 extends to grab the empty yarn tube on the dragging platform 40.

[0052] Step 11: The lower rib 110 descends to the over-descent position, and the drag mechanism 30 moves forward to the yarn changing position;

[0053] Step 12: The lower rib 110 rises to the middle drag position, and the drag mechanism 30 moves to the doffing position;

[0054] Step 13: The lower rib 110 rises to the middle pin position, and the platform positioning moving rod 32 retracts;

[0055] Step 14: The lower rib 110 descends to the mounting position, and the dragging mechanism 30 moves forward to the spinning position;

[0056] Step 15: The lower rib 110 rises to the tube-retrieving position, the swing claw structure 20 retracts to release the tube, and the empty yarn tube is transferred to the lower rib 110;

[0057] Step 16: The lower duct 110 descends to the spinning start position and starts the automatic yarn feeding to begin spinning, completing the entire automatic yarn doffing process.

[0058] Note: The above steps are only arranged and described step by step to explain the doffing process. In actual operation, in order to save time, some steps are actually performed simultaneously, and some positions can be combined. For example, the yarn grabbing position / tube grabbing position can be combined with the yarn taking position / tube taking position.

[0059] This invention adds a swing claw structure, a drag mechanism, and a yarn-lifting platform to the existing old-style roving frame to achieve an automatic yarn doffing process. After the lower roving is full of yarn, it rises, and the full yarn tube temporarily rests on the spindle wing and is temporarily fixed by the swing claw structure. The yarn-lifting platform receives the full yarn tube from the spindle wing and moves forward, then removes the full yarn tube. Alternatively, through the reverse operation, an empty yarn tube is placed on the yarn-lifting platform, which moves backward, temporarily resting the empty yarn tube on the spindle wing and then removing the yarn-lifting platform. The lower roving then rises to receive the empty yarn tube. This achieves an automatic yarn doffing process, improves production efficiency, and requires no major modifications to existing equipment, making it highly practical.

[0060] In addition, through the cooperation of the swing claw structure 20 and the spindle wing and spindle rod 19, the yarn tube 04 that has completed spinning can stay briefly on the upper spindle wing and spindle rod 19, and fall onto the yarn support platform 40 after losing its grip.

[0061] Example 5;

[0062] In this embodiment, the lower spindle 110 has multiple placement columns 115, and the yarn tube 04 is placed on the upper end of the multiple placement columns 115. In the existing spinning process, the lower spindle 110 and the spindle 120 cooperate to complete the spinning. When the lower spindle 110 rises, the spindle 120's spindle rod 19 will enter the yarn tube 04, and then the yarn tube 04 will be clamped on the spindle rod 19 by the swing claw structure 20.

[0063] It should be noted that the spinning process completed by the lower spindle 110 through the spindle 120 is a conventional technology of existing roving frame equipment and will not be described in detail here.

[0064] Example 6;

[0065] like Figures 8 to 10 As shown, there are multiple spindle wings 120, arranged in two rows. Each spindle wing 120 corresponds to a placement column 115. The swing claw structure 20 is disposed between the two rows of spindle wings 120 at the upper end of the main frame 10. The swing claw structure 20 includes a fixed plate 21, a movable plate 22, a swing claw 210, and a telescopic member 23. The fixed plate 21 is connected to the upper rib 130. There are multiple swing claws 210, each rotatably disposed on the side of the movable plate 22. The inner end of the swing claw 210 is rotatably connected to the movable plate 22. The middle part 201 of the swing claw 210 is connected to... The fixed plate 21 is rotatably connected. The outer end of the swing claw 210 is used to clamp the yarn tube 04. The telescopic member 23 is used to drive the moving plate 22 to move. Each swing claw 210 corresponds to a spindle wing 120. The swing claw 210 includes a rotating plate 211 and a U-shaped plate 212. The inner end of the rotating plate 211 is rotatably connected to the moving plate 22. The middle part of the rotating plate 211 is rotatably connected to the fixed plate 21. The U-shaped plate 212 is located at the outer end of the rotating plate 211. The upper end of the U-shaped plate 212 is an arc plate 213. The lower ends of the two vertical rods 214 of the U-shaped plate 212 are provided with ear plates 215.

[0066] When the spindle wing and spindle rod 19 enter the yarn tube 04, the telescopic member 23 extends, driving the moving plate 22 to move. The moving plate 22 drives multiple rotating plates 211 to rotate in the direction of the spindle wing and spindle rod 19 of the multiple spindle wings 120, so that the two ear plates 215 at the lower end of the U-shaped plate 212 clamp the protrusion 05 or groove at the upper end of the yarn tube 04. Through the setting of the arc plate 213, the rotation of the U-shaped plate 212 driven by the rotating plate 211 is not affected. When the telescopic member 23 retracts, it loses the clamping effect on the yarn tube 04.

[0067] Preferably, when the yarn tube 04 rises to the designated position along the spindle arm 19 and the spindle arm swings to the designated angle, the structure is activated, and then the telescopic component 23 begins to work. The spindle arm 18 of the roving frame has a rotation function, which is an original function of the roving frame and will not be described in detail here. The spindle arm 18 is rotated to a suitable angle to avoid affecting the clamping action of the swing claw.

[0068] More preferably, the telescopic component 23 is, for example, a cylinder structure or an electric telescopic rod.

[0069] Example 7;

[0070] like Figures 4 to 7 As shown, there are multiple horizontal moving guide rails 50, each including a fixed block 51, a drive gear 52, a toothed plate 53, a moving plate 54, and a vertical guide post 55. The fixed block 51 is set on the ground. The moving plate 54 is movably mounted on the guide block 511 of the fixed block 51 via a recessed groove 56. The vertical guide post 55 is located on the upper outer end of the moving plate 54. The toothed plate 53 is located on one side of the moving plate 54. The drive gear 52 meshes with the toothed plate 53. A driven wheel 58 is provided on the rotating rod 57, and the driven wheel 58 is connected to the drive wheel 59 via a belt 61. The motor drives the drive wheel 59 to move, and the belt 61 causes the driven wheel 58 and the rotating rod 57 to rotate. The rotating rod 57 drives the drive gear 52 to move in multiple positions, thereby driving the toothed plate 53 to move horizontally. The motor used to drive the drive wheel 59 is mounted on the ground via a mounting plate 78. The mounting plate 78 has multiple mounting holes. By selecting mounting holes at different positions using fasteners, the drive wheel 59 can be mounted on the ground to adjust its tension.

[0071] Preferably, Figure 23 As shown, the rotating rod 57 is rotatably mounted on the fixed body 75, and the driving gears 52 are respectively installed at both ends of the rotating rod 57, thus achieving a driving effect for multiple positions; it also includes a stabilizing frame 76, which is mounted on the rotating rod 57 via a stabilizing bearing 77. The stabilizing frame 76 is fixed to the ground.

[0072] The platform positioning moving rod 32 is provided in multiple ways. These multiple platform positioning moving rods 32 are retractably mounted on the vertical guide column 55. The multiple platform positioning moving rods 32 are connected to the horizontal moving rod 34 via a connecting plate 33. The horizontal moving rod 34 is controlled by a telescopic cylinder 35 or an electric telescopic rod. That is, when the telescopic cylinder 35 drives the horizontal moving rod 34 to move horizontally, the connecting plate 33 will move the platform positioning moving rod 32 at multiple positions, causing the platform positioning moving rod 32 to extend or retract from the vertical guide column 55. When extended, it can be used to position and support the yarn-supporting platform 40.

[0073] Furthermore, the vertical guide post 55 has a slidable drive card 551, which is connected to the yarn-supporting platform 40. The two sides of the drive card 551 are slidably mounted on the guide protrusions 553 of the vertical guide post 55, held by sliding wheels 552. Figure 7 As shown, when the platform positioning moving rod 32 extends from the vertical guide post 55 and when the yarn-supporting platform 40 rises, the platform positioning moving rod 32 can be used to support and fix the driving card 551, thereby forming support for the yarn-supporting platform 40.

[0074] More preferably, the driving card 551 has a fixing piece 501 and a bending piece 502. The inner side of the fixing piece 501 cooperates with the guide protrusion 553 on the vertical guide post 55 through the first guide wheel 503 and the second guide wheel 504. The receiving part 505 of the bending piece 502 is used to support and lift the yarn support platform 40.

[0075] By extending the telescopic cylinder 42, the platform positioning moving rod 32 moves forward, thus supporting the yarn-supporting platform 40. Subsequently, the motor structure drives the drive wheel 59 to rotate, which in turn drives the driven wheel 58 to rotate via the belt 61. The driven wheel 58 drives the rotating rod 57 to rotate, which in turn drives the drive gear 52 to rotate. The drive gear 52, through the action of the toothed plate 53, drives the moving plate 54 to move. The moving plate 54 moves along the fixed block 51 through the recessed groove 56, causing the vertical guide column 55 to move the yarn-supporting platform 40 forward. When the drive motor reverses, the yarn-supporting platform 40 moves towards the main frame 10, and the telescopic cylinder 42 retracts, causing the platform positioning moving rod 32 to lose support for the yarn-supporting platform 40. At this time, through the cooperation of the passive plate 31 and the driving plate 111, the yarn-supporting platform 40 moves down to its lowest position.

[0076] In another movement: after the yarn tube 04 is fully loaded with yarn, the lower rib 110 moves upward so that the spindle wing 19 enters the middle of the yarn tube 04; the transverse moving guide rail 50 drives the yarn support platform 40 to move outward towards the outside of the main frame 10.

[0077] The operation is performed via the swing claw structure 20, which clamps and fixes the completed yarn tube 04 onto the spindle wing and spindle rod 19. Then, the lower rib 110 descends, achieving the desired effect. Figure 15 The state shown.

[0078] The transverse moving guide rail 50 drives the yarn-supporting platform 40 to move inward toward the inside of the main frame 10, so that the projection of the passive plate 31 is above the driving plate 111; at this time, the lower rib 110 rises, and the driving plate 111 on the lower rib 110 will contact the passive plate 31, thus driving the yarn-supporting platform 40 to move upward. When the yarn-supporting platform 40 moves upward to the center pin position, the platform positioning moving rod 32 extends to support the yarn-supporting platform 40 and prevent the yarn-supporting platform 40 from moving downward; at this time, the entire yarn-supporting platform 40 is still located below the lower rib 110, thus achieving the desired position. Figure 16 and Figure 17 The state shown;

[0079] The lateral moving guide rail 50 drives the yarn-supporting platform 40 to move forward again, and the lower rib 110 moves downward, thus achieving the desired effect. Figure 18 The state shown; then the lateral moving guide rail 50 drives the yarn-supporting platform 40 to move backward, so that the yarn-supporting platform 40 moves to the upper side of the lower rib 110, thus achieving the state shown. Figure 19 As shown in the diagram; the lower rib 110 rises again, and the upper end of the lower rib 110 contacts the lower end of the yarn support platform 40, causing the yarn support platform 40 to move upward again until the yarn support platform 40 receives the yarn tube 04 located on the spindle wing spindle rod 19. At the same time, the swing claw structure 20 loses its grip on the yarn tube, so that the yarn tube 04 falls uniformly onto the yarn support platform 40.

[0080] At this time, the lower rib 110 moves down, which drives the yarn support platform 40 that supports the yarn tube 04 to move down until the yarn support platform 40 drops to the first height position, and then is supported again by the platform positioning and moving rod 32.

[0081] The transverse moving guide rail 50 drives the yarn support platform 40 to move forward, causing the yarn tubes 04 held on the yarn support platform 40 to move outward. This realizes the process of automatically removing all the yarn tubes 04 from the lower rib 110, replacing the manual tube lowering process and realizing automated operation.

[0082] Additionally, it includes the step of empty pipe loading:

[0083] The lateral moving guide rail 50 drives the yarn support platform 40 to move outward, loading an empty yarn tube onto the yarn support platform 40;

[0084] The transverse moving guide rail 50 drives the yarn support platform 40 to move inward and to the upper side of the lower rib 110;

[0085] The lower rib 110 moves upward and contacts the bottom of the yarn support platform 40, then drives the yarn support platform 40 to move upward until the yarn tube above the yarn support platform 40 enters the spindle wing rod 19 of the top position spindle wing.

[0086] The swing claw structure 20 switches positions to clamp and fix the yarn tube on the spindle wing and spindle rod 19;

[0087] As the lower rib 110 moves down, the yarn-supporting platform 40 follows and descends. When it reaches the first height position, i.e. the middle pin position, it is supported by the extended platform positioning and moving rod 32 so that the yarn-supporting platform 40 stays at the first height position.

[0088] The lower rib 110 moves down, and the horizontal moving guide rail 50 drives the yarn support platform 40 to move outward again, so that the L-shaped passive plate 31 is projected above the driving plate 111.

[0089] The lower rib 110 rises again until it drives the plate 111 to touch the L-shaped passive plate 31, and the platform positioning moving rod 32 loses its support.

[0090] The lower rib 110 descends again, and the L-shaped passive plate 31 and the yarn support platform 40 descend accordingly to their lowest positions;

[0091] The horizontal moving guide rail 50 once again drives the yarn support platform 40 to move outward, so that the projection of the L-shaped passive plate 31 is no longer above the driving plate 111;

[0092] The lower rib 110 moves upward until it receives the empty yarn tube of the top spindle wing spindle rod 19, and the swing claw structure 20 switches positions and loses the clamping and fixing of the yarn tube on the spindle wing spindle rod 19.

[0093] The empty yarn tube is then transferred to the lower reinforcing bar 110.

[0094] Example 8;

[0095] like Figure 8 As shown, the yarn-supporting platform 40 includes a plate 45, multiple yarn-supporting plates 46, and a receiving column 47. The plate 45 is slidably mounted on the vertical guide column 55 by driving the card 551. The multiple yarn-supporting plates 46 are respectively disposed at the inner end of the plate 45, and the receiving column 47 is respectively disposed in each yarn-supporting plate 46.

[0096] When the yarn-supporting platform 40 moves upward to receive the yarn tube, the receiving column 47 will enter the lower end of the yarn tube. At the same time, the swing claw structure 20 loses its grip on the protrusion 05 or groove at the upper end of the yarn tube 04. At this time, the yarn-supporting platform 40 moves downward, causing the yarn tube to move downward. When the yarn-supporting platform 40 moves to the middle position, it is supported by the platform positioning moving rod 32. At this time, the moving plate 54 moves forward along the fixed block 51 through the recessed groove 56, thereby driving the yarn-supporting platform 40 to move forward, so that multiple yarn tubes can be removed at one time.

[0097] refer to Figure 5Additionally, a liftable yarn-lifting platform structure 90 is provided above the dragging mechanism 30. The yarn-lifting platform 90 is positioned above and to the outside of the main frame 10. The yarn-lifting platform structure 90 is used to lift all the yarn tubes supported by the yarn-supporting platform 40. The function of the yarn-lifting platform structure 90 is to remove the yarn tubes 04 from the dragging mechanism 30 in one go, thereby further automating the yarn tube transfer process. Preferably, the yarn-lifting platform structure 90 has a liftable gripper structure; after being lowered, the gripper can remove or place the yarn tubes 04 from the dragging mechanism 30.

[0098] In other embodiments, the yarn-supporting platform 40 can be raised and lowered without being driven by the lower reinforcing bar 110. In this case, a lifting drive component can be set on the drag mechanism 30 alone, eliminating the need for the driving plate and the driven plate. That is, the yarn tube receiving process can also be completed by directly driving the yarn-supporting platform 40 to raise and lower through the lifting drive component; however, this embodiment will increase costs.
