Abstract

The utility model provides a dragging mechanism for improving a doffing mode of a roving frame. The dragging mechanism comprises a yarn supporting platform, a transverse moving guide rail, a vertical guide column, a driven plate and a platform positioning moving rod. A telescopic platform positioning moving rod is arranged on the vertical guide column and is used for supporting the yarn supporting platform; the yarn supporting platform can be vertically and movably arranged on the vertical guide column, and a driven plate is arranged on the side portion of the yarn supporting platform. The transverse moving guide rail is used for driving the yarn supporting platform and the vertical guide column to transversely move. According to the dragging mechanism, the transverse moving guide rail can drive the yarn supporting platform to move horizontally, so that the yarn supporting platform can go deep into the position between the lower keel and the upper keel so as to be used for bearing bobbins full of yarn or transferring empty bobbins to the upper keel. When the yarn supporting platform is located on the outer side, the yarn supporting platform can be exchanged with the yarn hanging platform, namely, the full-yarn bobbins are transferred to the yarn hanging platform, and the empty bobbins can be transferred to the yarn supporting platform through the yarn hanging platform.

Description

Technical Field

[0001] The utility model relates to a roving frame with an improved doffing mode, in particular to a technology which is improved on an old-fashioned roving frame and assists in realizing automatic doffing. Background Art

[0002] The later process of the roving frame equipment includes the process of spinning and winding, that is, the yarn is continuously spit out and wound on the bobbin. The existing technology still uses the old roving frame when spinning, and the bobbins used on the old roving frame need to be replaced one by one manually, that is, the process of automatic yarn dropping (including taking away the full yarn bobbins and placing the empty bobbins) cannot be realized.

[0003] like Figure 1 and Figure 2 As shown, it is an existing old-style roving machine, which has a main frame body 01, a spindle wing 02, a lower rib 03 and an upper rib 05. The lower rib 03 is arranged on the main frame body 01 in a liftable manner. The upper rib 05 is arranged on the upper end of the main frame body 01. The spindle wing 02 is provided below the upper rib 05. The lower rib 03 is used to place the yarn tube 04, and the spindle wing 02 is used to spin yarn onto the yarn tube 04. The equipment and the working process belong to the existing technology and will not be repeated here.

[0004] However, in the existing old-fashioned roving machine, when spinning is completed, the full yarn tubes need to be removed from the lower rib of the spinning machine manually (the full yarn tubes are removed and the empty yarn tubes are replaced), which is very troublesome. Similarly, when the empty tubes are loaded onto the lower rib, they also need to be placed manually one by one; the lower rib of this traditional old-fashioned roving machine only has a lifting function, and it cannot move horizontally and leave the main frame, so it becomes very difficult to automatically doff yarn from the upper position.

[0005] In response to this technical problem, the first technical problem to be solved is how to provide a dragging mechanism, that is, to use the dragging mechanism to reach the position of the lower and upper ribs of the roving frame, thereby removing the yarn tube or placing an empty yarn tube, so as to realize the automatic yarn dropping process. Utility Model Content

[0006] In order to solve the problems existing in the above-mentioned technology, the utility model provides an improvement on the old-fashioned equipment, and accordingly proposes the concept of a dragging mechanism, which assists the process of automatic yarn dropping through the dragging mechanism.

[0007] The utility model provides a dragging mechanism for improving the yarn dropping mode of a roving machine, which comprises a yarn supporting platform, a transverse moving guide rail, a vertical guide column, a passive plate and a platform positioning and moving rod; a retractable platform positioning and moving rod is arranged on the vertical guide column, and the platform positioning and moving rod is used to support the yarn supporting platform; the yarn supporting platform can be vertically movably arranged on the vertical guide column, and the side of the yarn supporting platform is provided with the passive plate; the transverse moving guide rail is used to drive the yarn supporting platform and the vertical guide column to move transversely.

[0008] Preferably, there are multiple transverse movable guide rails, and the multiple transverse movable guide rails include a fixed block, a driving gear, a tooth plate and a movable plate. The fixed block is set on the ground, and the movable plate is movably set on the fixed block through a recessed groove. The vertical guide column is set on the upper side of the outer end of the movable plate, and the tooth plate is set on one side of the movable plate. The driving gear is meshed and connected with the tooth plate.

[0009] Preferably, a belt drives the driven wheel to rotate, the driven wheel drives the rotating rod to rotate, and the rotating rod drives the driving gear to rotate.

[0010] Preferably, the platform positioning moving rod is telescopically arranged on the vertical guide column, and the platform positioning moving rods at multiple positions are connected to the horizontal motion rod through a connecting plate.

[0011] Preferably, the yarn supporting platform includes a plate body, a plurality of yarn supporting plates, and a receiving column. The plate body can be slidably set on the vertical guide column by driving the card. The plurality of yarn supporting plates are respectively arranged at the inner end of the plate body, and the receiving column is respectively arranged in each of the yarn supporting plates.

[0012] Preferably, the vertical guide column is provided with a slidable driving card, which is connected to the yarn supporting platform; the two sides of the driving card are clamped by sliding wheels and are slidably arranged on the guide protrusions of the vertical guide column.

[0013] The utility model provides a dragging mechanism for improving the yarn dropping mode of a roving frame, which can perform lateral horizontal movement, so that it can penetrate into the roving frame, that is, move between the lower rib and the upper rib of the roving frame, and the lower rib can drive the dragging platform to move to a required height, so that the process of taking away the yarn tube or placing the empty tube can be completed at different height positions, thereby completing the auxiliary work of automatic yarn dropping.

[0014] In addition, the dragging mechanism in the present application cooperates with the swing claw structure and the yarn hanging platform to complete the process of automatic yarn dropping.

[0015] During the specific process, the utility model, on the existing old-style roving machine, the lower dragon bar rises after being full of yarn, and the full yarn tube temporarily stays on the spindle wing spindle rod and is temporarily fixed by a swing claw structure; the full yarn tube on the spindle wing spindle rod is received by the yarn supporting platform, and after moving to the front side, the yarn hanging platform takes away the full yarn tube; in addition, through the reverse operation, the empty yarn tube is placed on the yarn supporting platform through the yarn hanging platform, and the yarn supporting platform moves to the rear side, and the empty yarn tube is temporarily stopped on the spindle wing spindle rod, the yarn supporting platform is removed, and the lower dragon bar rises to receive the empty yarn tube; thereby, the automatic yarn dropping process is realized, the production efficiency is improved, and no major changes are required to the existing equipment, and it has strong practicality.

[0016] The yarn hanging platform can exchange the empty bobbin it carries with the full bobbin on the yarn supporting platform moving outward, so that the dragging mechanism works in reverse and the empty bobbin is placed on the lower dragon bar. The swing claw mechanism, the dragging mechanism and the yarn hanging platform are reset to their original states, ensuring that the main machine of the roving frame can start spinning normally and the doffing system is in a standby state for the next doffing cycle.

[0017] The lower dragon tendon drives the bobbin upward. When the bobbin rises to the specified position along the spindle wing spindle rod and the spindle wing arm swings to the specified angle, the swing claw structure clamps the bobbin and fixes the bobbin on the spindle wing spindle rod. Then the lower dragon tendon descends, and the driving plate on one side of the lower dragon tendon cooperates with the passive plate. The lower dragon tendon drives the yarn supporting platform to rise. When the yarn supporting platform rises to the middle position, the yarn supporting platform is supported by the platform positioning moving rod, and then the horizontal moving guide rail drives the yarn supporting platform to move forward. At this time, the lower dragon tendon descends. The yarn supporting platform is lowered to the lower position of the yarn supporting platform, and then the horizontal moving guide rail drives the yarn supporting platform to move backward, so that the yarn supporting platform is located on the upper side of the lower dragon tendon. The upper end of the lower dragon tendon contacts the lower end of the yarn supporting platform and drives the yarn supporting platform to rise. The yarn supporting platform receives the yarn tube on the yarn tube receiving column, and the swing claw structure loses its grip on the yarn tube. The lower dragon tendon drives the yarn supporting platform to move down to the middle position, and the platform positioning moving rod supports it. The horizontal moving guide rail drives the yarn supporting platform forward and can take away the yarn tube, thereby realizing the process of automated tube lowering.

[0039] Embodiment 1:

[0040] like Figures 4 to 7 As shown, the present embodiment is a dragging mechanism for improving the yarn dropping mode of the roving frame, which 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 moving rod 32; a retractable platform positioning moving rod 32 is arranged on the vertical guide column 55, and the platform positioning moving rod 32 is used to support the yarn supporting platform 40; the yarn supporting platform 40 is vertically movably arranged on the vertical guide column 55, and the side of the yarn supporting platform 40 is provided with the passive plate 31; the transverse moving guide rail 50 is used to drive the yarn supporting platform 40 and the vertical guide column 55 to move transversely.

[0041] In the dragging mechanism of this embodiment, the lateral moving guide rail 55 can drive the yarn supporting platform 40 to move horizontally, so that the yarn supporting platform 40 can go deep into the position between the lower dragon tendon 110 and the upper dragon tendon to receive the full yarn tube or transfer the empty tube to the upper dragon tendon. When the yarn supporting platform 40 is in the outer position, it can be exchanged with the hanging yarn platform 90, that is, the full yarn tube is transferred to the hanging yarn platform 90, and the hanging yarn platform 90 can transfer the empty tube to the yarn supporting platform 40. In addition, the yarn supporting platform 40 can move vertically with the help of the lifting function of the lower dragon tendon 110, and the side of the yarn supporting platform 40 has a passive plate 31, so that the lower dragon tendon 110 can drive the yarn supporting platform 40 to rise or directly lift the bottom of the yarn supporting platform 40 through the passive plate 31, and the yarn supporting platform 40 is supported by the platform positioning moving rod 32, so that the free switching of multiple mutual positions of the lower dragon tendon 110 and the yarn supporting platform 40 is realized, and the specific process is described below.

[0042] Embodiment 2:

[0043] The lateral moving guide rails 50 have a plurality of them, and the plurality of lateral moving guide rails 50 include a fixed block 51, a driving gear 52, a tooth plate 53 and a moving plate 54. The fixed block 51 is set on the ground, and the moving plate 54 is movably set on the fixed block 51 through a recessed groove 56. The vertical guide column 55 is set on the upper side of the outer end of the moving plate 54, and the tooth plate 53 is set on one side of the moving plate 54. The driving gear 52 is meshed and connected with the tooth plate 53. The vertical guide column 55 is set on the upper side of the outer end of the moving plate 54.

[0044] The driven wheel 58 is driven to rotate by the belt 61 , the driven wheel 58 drives the rotating rod 57 to rotate, and the rotating rod 57 drives the driving gear 52 to rotate.

[0045] When the belt 61 is driven, the driven wheel 58 is driven to rotate, and the driven wheel 58 drives the rotating rod 57 to rotate, thereby driving the driving gears 52 at multiple positions to rotate. The movement of the driving gear 52 causes the tooth plate 53 to drive the moving plate 54 to move horizontally. The vertical guide column 55 follows the horizontal movement, and accordingly drives the horizontal movement of the yarn supporting platform 40.

[0046] The platform positioning moving rod 32 is telescopically arranged on the vertical guide column 55, and the platform positioning moving rod 32 at multiple positions is connected to the horizontal movement rod 34 through the connecting plate 33. When the cylinder structure or other telescopic structure drives the horizontal movement rod 34 to move, the connecting plate 33 drives the platform positioning moving rod 32 to extend or retract on the vertical guide column 55, so that it can be used to support the yarn supporting platform 40 that can be vertically lifted and lowered.

[0047] The yarn supporting platform 40 includes a plate body 45, a plurality of yarn supporting plates 46, and a receiving column 47. The plate body 45 can be slidably set on the vertical guide column 55 by driving the card 551. The plurality of yarn supporting plates 46 are respectively arranged at the inner end of the plate body 45, and the receiving column 47 is respectively arranged in each of the yarn supporting plates 46.

[0048] The vertical guide column 55 has a slidable driving card 551, which is connected to the yarn supporting platform 40; the two sides of the driving card 551 are clamped by sliding wheels 552 and slidably arranged on the guide protrusions of the vertical guide column 55. This structure allows the yarn supporting platform 40 to move vertically along the vertical guide column 55, but when the vertical guide column 55 moves horizontally, the driving card 551 drives the yarn supporting platform 40 to move.

[0049] The utility model provides a dragging mechanism for improving the yarn dropping mode of a roving frame, which can perform lateral horizontal movement, so that it can penetrate into the roving frame, that is, move between the lower rib and the upper rib of the roving frame, and the lower rib can drive the dragging platform to move to a required height, so that the process of taking away the yarn tube or placing the empty tube can be completed at different height positions, thereby completing the auxiliary work of automatic yarn dropping.

[0050] In addition, the dragging mechanism in the present application cooperates with the swing claw structure 20 and the yarn hanging platform 90 to complete the process of automatic yarn dropping. The specific process is as follows:

[0051] First embodiment:

[0052] like Figures 3 to 11 As shown, the utility model provides a roving frame with an improved yarn doffing method, comprising a main frame 10, a swing claw structure 20, a dragging mechanism 30 and a yarn hanging platform 90;

[0053] The lower end of the main frame body 10 is provided with a lower rib 110 that can be raised and lowered. The lifting system of the lower rib 110 belongs to the inherent technology of this equipment and will not be described here. The lower rib 110 is provided with a driving plate 111. The upper end of the main frame body 10 is provided with an upper rib 130. N flyers 120 are provided on the upper rib 130. The flyers 120 have flyer bars 19.

[0054] The swing claw structure 20 is arranged on the bottom surface 131 of the upper dragon tendon 130, and the swing claw structure 20 is used to clamp and fix the bobbin 04 on the flyer spindle rod 19;

[0055] The dragging mechanism 30 is arranged on the lower side of the main frame 10, and 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 transversely. The side of the yarn supporting platform 40 has a passive plate 31, and the passive plate 31 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 is provided with a retractable platform positioning moving rod 32.

[0056] The yarn hanging platform 90 is arranged at the upper outer side of the main frame 10, and is used to exchange empty yarn tubes and full yarn tubes with the dragging mechanism 30. An empty yarn tube refers to a yarn tube without yarn, and a full yarn tube refers to a yarn tube that has been spun; the yarn hanging platform 90 can load and place an empty yarn tube on the dragging mechanism 30, and can take away the full yarn tube on the dragging mechanism 30.

[0057] Preferably, Fig.11In the embodiment, the top of the yarn hanging platform 90 is connected to the bottom of the main frame 10 through a lifting rope 91, and the side of the yarn hanging platform 90 is slidably arranged in the sliding groove 101 of the main frame 10 through a guide pulley 92; the yarn hanging platform 90 has a rotating wheel 93, an empty hanging spindle 94 and a hanging spindle transmission steel belt 95, and the hanging spindle transmission steel belt 95 is sleeved on the rotating wheel 93, and multiple groups of empty hanging spindles 94 are arranged on the hanging spindle transmission steel belt 95. The rotating wheel 93 rotates to make the hanging spindle transmission steel belt 95 move, so that the empty hanging spindle 94 rotates, and each empty hanging spindle 94 is a gripper for gripping and fixing a bobbin. Through the lifting action of the lifting rope 91, the yarn hanging platform 90 can drive the empty hanging spindle 94 to descend to the position of the yarn dragging platform 40, so that the action of grabbing the full yarn bobbin and taking it away can be completed, and the action of placing the empty bobbin can also be completed. The lifting rope 91 can also be a lifting rod, and this lifting action adopts the existing technology, which will not be repeated here.

[0058] like Figures 12 to 21 As shown, the process of the device of this embodiment in a specific application is:

[0059] After spinning full yarn, the following actions are performed:

[0060] Step 1: The lower dragon tendon 110 drives the full yarn (the state of the full yarn bobbin) to rise to the yarn grabbing position, and extends the swing claw structure 20 to grab the yarn;

[0061] Step 2: The lower dragon tendon 110 descends to the mounting position; in the height direction, the positions where the lower dragon tendon 110 stays from bottom to top are: super-drop position, mounting position, middle drag position, middle pin position and yarn grabbing position (yarn taking position), the super-drop position is the lowest position where the lower dragon tendon 110 descends, the mounting position is the position where the driving plate 111 of the lower dragon tendon 110 is used to drive the passive plate 31 on the side of the yarn supporting platform 40 to rise; the middle supporting position is a position where the lower dragon tendon 110 temporarily stays; the middle pin position refers to the position where the platform positioning moving rod 32 supports the yarn supporting platform 40.

[0062] Step 3: The dragging mechanism 30 moves from the spinning position to the doffing position; the driving plate 111 and the passive plate 31 of the lower dragon tendon 110 overlap each other;

[0063] Step 4: The lower dragon tendon 110 drives the yarn supporting platform 40 to rise to the middle pin position, and the platform positioning moving rod 32 extends;

[0064] Step 5: The lower dragon tendon 110 descends to the middle dragging position, the passive plate of the yarn supporting platform 40 is separated from the driving plate of the lower dragon tendon 110, the dragging mechanism 30 moves forward from the yarn dropping position to the yarn changing position, and the yarn supporting platform 40 leaves the lower dragon tendon 110;

[0065] Step 6: The lower dragon tendon 110 is lowered to the super-lowering position, which is lower than the yarn supporting platform 40, and the dragging mechanism 30 moves backward to the yarn dropping position, and the yarn supporting platform 40 is placed above the lower dragon tendon 110;

[0066] Step 7: The lower dragon tendon 110 pushes the yarn supporting platform 40 up to the yarn taking position, the swing claw structure 20 is retracted, and the full yarn is placed on the yarn supporting platform 40;

[0067] Step 8: The dragging mechanism 30 follows the lower dragon tendon 110 and descends to the super-descent position, the doffing platform 40 and the lower dragon tendon 110 are separated up and down, and the dragging mechanism 30 moves forward from the doffing position to the yarn changing position;

[0068] Step 9: The yarn hanging platform 90 descends, and the empty hanging spindle 91 on the yarn hanging platform 90 grabs the full yarn bobbin on the dragging mechanism 30. The yarn hanging platform 90 hangs the full yarn on the yarn supporting platform 40 and rises to a certain height. The hanging spindle transmission steel belt 92 inside the yarn hanging platform 90 rotates a spindle distance, so that the empty yarn tube on the yarn hanging platform 90 is aligned with the receiving column on the yarn supporting platform 40. The yarn hanging platform 90 descends, and the empty yarn tube on the yarn hanging platform 90 is placed on the yarn supporting platform 40. The yarn hanging platform 90 rises to the original position;

[0069] Step 10: The dragging platform 40 moves backward to the yarn dropping position, the lower dragon tendon 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;

[0070] Step 11: The lower dragon tendon 110 descends to the super-descent position, and the dragging mechanism 30 moves forward to the yarn changing position;

[0071] Step 12: The lower dragon tendon 110 rises to the middle dragging position, and the dragging mechanism 30 moves backward to the doffing position;

[0072] Step 13: The lower dragon tendon 110 rises to the middle pin position, and the platform positioning moving rod 32 is retracted;

[0073] Step 14: The lower dragon tendon 110 descends to the mounting position, and the dragging mechanism 30 moves forward to the spinning position;

[0074] Step 15: The lower dragon tendon 110 rises to the tube taking position, the swing claw structure 20 retracts the tube spreading, and the empty bobbin is transferred to the lower dragon tendon 110;

[0075] Step 16: The lower dragon tendon 110 descends to the spinning starting position to start the automatic spinning and start spinning, completing the entire process of automatic yarn dropping.

[0076] Note: The above steps are arranged and described step by step only to explain the yarn dropping process. In actual operation, in order to save time, some step-by-step actions are actually performed simultaneously, and some positions can also be combined, for example, the yarn grabbing position / tube grabbing position can be combined with the yarn taking position / tube taking position.

[0077] The utility model newly adds a swing claw structure, a dragging mechanism and a yarn hanging platform to the existing old-style roving machine to realize the automatic yarn dropping process; the lower dragon bar rises after being full of yarn, and the full yarn tube temporarily stays on the wing spindle rod and is temporarily fixed by the swing claw structure; the full yarn tube on the wing spindle rod is received by the yarn supporting platform, and after moving to the front side, the full yarn tube is taken away by the yarn hanging platform; in addition, through reverse operation, the empty yarn tube is placed on the yarn supporting platform through the yarn hanging platform, and the yarn supporting platform moves to the rear side, and the empty yarn tube is temporarily stopped on the wing spindle rod, the yarn supporting platform is removed, and the lower dragon bar rises to receive the empty yarn tube; thereby, the automatic yarn dropping process is realized, the production efficiency is improved, and no major changes are required to the existing equipment, and the utility model has strong practicality.

[0078] In addition, through the cooperation of the swing claw structure 20 and the flyer spindle rod 19, the yarn tube 04 that has completed spinning can stay on the flyer spindle rod 19 above for a short time, and fall onto the yarn supporting platform 40 after losing the clamping later.

[0079] Second embodiment;

[0080] In this embodiment, the lower dragon bar 110 is provided with a plurality of placement columns 115, and the yarn tube 04 is placed on the upper ends of the plurality of placement columns 115; in the existing spinning process, the lower dragon bar 110 and the spindle wing 120 cooperate to complete the spinning; the lower dragon bar 110 rises, and the spindle wing spindle rod 19 of the spindle wing 120 will enter into the yarn tube 04, and then the yarn tube 04 is clamped on the spindle wing spindle rod 19 through the swing claw structure 20.

[0081] It should be noted that the spinning process completed by the lower rib 110 through the spindle 120 belongs to the conventional technology of the existing roving frame equipment and will not be described in detail here.

[0082] Third embodiment;

[0083] like Figures 8 to 10As shown, the ingot wing 120 has a plurality of ingot wings 120, and the plurality of ingot wings 120 form two rows, each of the ingot wings 120 corresponds to a placement column 115, and the swing claw structure 20 is arranged between the two rows of ingot wings 120 at the upper end of the main frame body 10, and the swing claw structure 20 includes a fixed plate 21, a movable plate 22, a swing claw 210 and a telescopic member 23, and the fixed plate 21 is connected to the upper dragon tendon 130, and the swing claw 210 has a plurality of ingot wings 210, and the plurality of ingot wings 210 are rotatably arranged on the side of the movable plate 22, and the inner end of the swing claw 210 is rotatably connected to the movable plate 22, and the middle part 201 of the swing claw 210 is connected to the movable plate 22. 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 movable plate 22 to move, each of the swing claws 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 movable plate 22, the middle part of the rotating plate 211 is rotatably connected to the fixed plate 21, the U-shaped plate 212 is arranged at the outer end of the rotating plate 211, the upper end of the U-shaped plate 212 is an arc plate 213, and the lower ends of the two vertical rods 214 of the U-shaped plate 212 are provided with ear plates 215.

[0084] When the flyer spindle rod 19 enters into the yarn tube 04, the telescopic part 23 extends, driving the movable plate 22 to move. The movement of the movable plate 22 drives multiple rotating plates 211 to rotate toward the flyer spindle rods 19 of multiple flyers 120 respectively, 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, and through the setting of the arc plate 213, it will not affect the rotation of the U-shaped plate 212 driven by the rotating plate 211. When the telescopic part 23 contracts, the clamping effect on the yarn tube 04 is lost one after another.

[0085] Preferably, when the bobbin 04 rises to a specified position along the flyer bar 19 and the flyer arm swings to a specified angle, the telescopic member 23 works again. The flyer arm 18 of the roving frame has a rotation function, which is an original function of the roving frame and will not be described here. The flyer arm 18 rotates to a suitable angle to avoid affecting the clamping action of the swing claw.

[0086] Further preferably, the telescopic member 23 is, for example, a cylinder structure or an electric telescopic rod.

The driving gear 52 is meshed and connected with the tooth plate 53. The rotating rod body 57 is provided with a driven wheel 58, and the driven wheel 58 is connected to the driving wheel 59 through a belt 61. The motor drives the driving wheel 59 to move, and the driven wheel 58 and the rotating rod body 57 are rotated through the belt 61. The rotating rod body 57 drives the driving gear 52 to move at multiple positions, thereby driving the tooth plate 53 to move horizontally.

[0089] There are multiple platform positioning moving rods 32, and multiple platform positioning moving rods 32 are telescopically arranged on the vertical guide column 55. Multiple platform positioning moving rods 32 are connected to the horizontal movement rod 34 through the connecting plate 33, and the horizontal movement rod 34 is controlled by the telescopic cylinder 35 or the electric telescopic rod. That is, when the telescopic cylinder 35 drives the horizontal movement rod 34 to move horizontally, the connecting plate 33 will drive the platform positioning moving rod 32 to move at multiple positions, that is, the platform positioning moving rod 32 passes through or retracts from the vertical guide column 55. After passing through, it can be used to position and support the yarn supporting platform 40;

[0090] Furthermore, the vertical guide column 55 has a slidable driving card 551, and the driving card 551 is connected to the yarn supporting platform 40. The two sides of the driving card 551 are clamped by sliding wheels 552 and slidably arranged on the guide protrusions 553 of the vertical guide column 55. Figure 7 As shown, when the platform positioning moving rod 32 extends from the vertical guide column 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.

[0091] By extending the telescopic cylinder 42, the platform positioning moving rod 32 moves forward, so that the platform positioning moving rod 32 supports the yarn supporting platform 40, and then the driving wheel 59 is driven to rotate by the motor structure, and the driven wheel 58 is driven to rotate by the belt 61, and the driven wheel 58 drives the rotating rod body 57 to rotate, and the rotating rod body 57 drives the driving gear 52 to rotate, and the driving gear 52 drives the moving plate 54 to move through the action of the toothed plate 53, and the moving plate 54 moves along the fixed block 51 through the recessed groove 56, so that the vertical guide column 55 drives the yarn supporting platform 40 to move forward, and the driving motor is reversed, and the yarn supporting platform 40 will move toward the main frame 10, and the telescopic cylinder 42 will contract, so that the platform positioning moving rod 32 loses its support for the yarn supporting platform 40. At this time, the yarn supporting platform 40 will move down to the lowest position through the cooperation of the passive plate 31 and the driving plate 111.

[0092] In another movement process: after the bobbin 04 is full of yarn, the lower dragon tendon 110 moves upward so that the flyer spindle rod 19 enters the middle part of the bobbin 04; the transverse moving guide rail 50 drives the yarn supporting platform 40 to move toward the outside of the main frame body 10;

[0093] The operation is performed by the swing claw structure 20, at which time the swing claw structure 20 clamps and fixes the completed spinning tube 04 on the spindle wing spindle rod 19, and then the lower dragon tendon 110 descends, that is, the Fig.15 Status shown.

[0094] The lateral moving guide rail 50 drives the yarn supporting platform 40 to move toward the inner side of the main frame body 10, that is, the projection of the passive plate 31 is located above the driving plate 111; at this time, the lower dragon tendon 110 rises, and the driving plate 111 on the lower dragon tendon 110 will contact the passive plate 31, thereby driving the yarn supporting platform 40 to move up. When the yarn supporting platform 40 moves up to the middle pin position; at this time, the platform positioning moving rod 32 extends to support the yarn supporting platform 40 to prevent the yarn supporting platform 40 from moving down; at this time, the yarn supporting platform 40 as a whole is still located below the lower dragon tendon 110, that is, it reaches the position as shown in the figure. Fig.16 and Fig.17 The status shown;

[0095] The lateral moving guide rail 50 drives the yarn supporting platform 40 to move forward again, and the lower dragon tendon 110 moves downward, that is, the yarn supporting platform 40 moves forward again, and ... Fig.18 After the lateral movement of the guide rail 50 drives the yarn supporting platform 40 to move backward, so that the yarn supporting platform 40 is moved to the upper side of the lower dragon tendon 110, that is, to achieve such Fig.19 The state shown; the lower dragon tendon 110 rises again, and the upper end of the lower dragon tendon 110 contacts the lower end of the yarn supporting platform 40, and drives the yarn supporting platform 40 to move up again until the yarn supporting platform 40 receives the bobbin 04 located on the spindle wing spindle rod 19, and at the same time, the swing claw structure 20 loses its grip on the bobbin, so that the bobbin 04 falls uniformly onto the yarn supporting platform 40;

[0096] At this time, the lower dragon tendon 110 moves downward to drive the yarn supporting platform 40 supporting the yarn tube 04 to move downward until the yarn supporting platform 40 drops to the first height position and is supported again by the platform positioning moving rod 32;

[0097] The laterally movable guide rail 50 drives the yarn supporting platform 40 to move forward, and the yarn tube 04 supported on the yarn supporting platform 40 moves outward, thus realizing the process of automatically removing all the yarn tubes 04 from the lower dragon tendon 110, replacing the process of manually lowering the tubes, and realizing automated operation.

[0098] In addition, the steps for empty tube loading are also included:

[0099] The transverse moving guide rail 50 drives the yarn supporting platform 40 to move outward, and loads the empty yarn tube onto the yarn supporting platform 40;

[0100] The lateral moving guide rail 50 drives the yarn supporting platform 40 to move inwards and move to the upper side of the lower dragon tendon 110;

[0101] The lower dragon tendon 110 moves upward and contacts the bottom of the yarn supporting platform 40, and then drives the yarn supporting platform 40 to move upward until the bobbin above the yarn supporting platform 40 enters the flyer spindle rod 19 of the top position flyer;

[0102] The swing claw structure 20 switches its position to clamp the bobbin on the flyer spindle rod 19;

[0103] The lower dragon tendon 110 moves downward, and the yarn supporting platform 40 follows the downward movement. When the yarn supporting platform 40 is at the first height position, i.e., the middle pin position, the yarn supporting platform 40 is supported by the extended platform positioning moving rod 32 so that the yarn supporting platform 40 stays at the first height position.

[0104] The lower dragon bar 110 moves downward, and the transverse moving guide rail 50 drives the yarn supporting platform 40 to move outward again, and the L-shaped passive plate 31 is projected above the driving plate 111;

[0105] The lower dragon tendon 110 rises again until the driving plate 111 touches the L-shaped passive plate 31, and the platform positioning moving rod 32 loses support;

[0106] The lower dragon tendon 110 descends again, and the L-shaped passive plate 31 and the yarn supporting platform 40 descend accordingly and reach the lowest position;

[0107] The transverse moving guide rail 50 drives the yarn supporting platform 40 to move outward again, so that the projection of the L-shaped passive plate 31 is not above the driving plate 111;

[0108] The lower dragon bar 110 moves upward until it receives the empty bobbin of the flyer spindle bar 19 of the top flyer, and the swing claw structure 20 switches its position and loses the bobbin that is clamped and fixed on the flyer spindle bar 19;

[0109] The empty bobbin is transferred to the lower tendon 110 .

[0110] Fifth embodiment;

[0111] like Figure 8 As shown, the yarn supporting platform 40 includes a plate body 45, a plurality of yarn supporting plates 46, and a receiving column 47. The plate body 45 can be slidably set on the vertical guide column 55 by driving the card 551. The plurality of yarn supporting plates 46 are respectively arranged at the inner end of the plate body 45, and the receiving column 47 is respectively arranged in each of the yarn supporting plates 46.

[0112] When the yarn supporting platform 40 moves up to receive the yarn tube, the receiving column 47 will enter into the lower end of the yarn tube, and 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 down, driving the yarn tube to move down. When the yarn supporting platform 40 moves down to the middle position, it is supported by the platform positioning moving rod 32. At this time, the movable plate 54 moves forward along the fixed block 51 through the recessed groove 56, thereby driving the yarn supporting platform 40 to move forward, and multiple yarn tubes can be taken away at one time.

[0113] refer to Figure 5 In addition, a liftable yarn hanging platform structure 90 is provided above the dragging mechanism 30. The yarn hanging platform 90 is provided above the outer side of the main frame 10. The yarn hanging platform structure 90 is used to lift all the yarn tubes supported by the yarn supporting platform 40. The yarn hanging platform structure 90 is used to remove the yarn tubes 04 on the dragging mechanism 30 at one time, thereby further realizing the automation process of the yarn tube transfer. Preferably, the yarn hanging platform structure 90 has a liftable gripper structure, and the gripper can be lowered to remove or place the yarn tube 04 from the dragging mechanism 30.

[0114] In other embodiments, the yarn supporting platform 40 may not be driven to move up and down by the lower dragon tendon 110. In this case, a lifting drive member is provided on the dragging mechanism 30 alone, and the driving plate and the passive plate are omitted. That is, the yarn supporting platform 40 may be directly driven to move up and down by the lifting drive member, and the process of receiving the bobbin may also be completed. However, this embodiment will increase the cost.
