Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to an automatic anti-winding device for bobbins and textile equipment. Background Technology

[0002] In textile machinery such as false-twist texturing machines, which require the final winding of yarn, a winding device is used to wind one or two continuous yarns into a conical or cylindrical shape. This type of yarn assembly is called a "spindle".

[0003] Chinese invention patent CN104787622B discloses an automatic yarn-generating control system and its control method for spinning bobbin changing. The system includes a black roller, an empty silo, an empty silo rocker arm, a bobbin holder that moves between a first position and a second position, and a full silo. When the bobbin holder is in the first position, it receives and clamps the empty bobbin transported by the empty silo rocker arm. When the bobbin holder is in the second position, the bobbin holder clamps the empty bobbin and contacts it with the black roller, rotating it to wind yarn. The system also includes a yarn-absorbing port located in front of the black roller, a yarn-catching plate that opens and closes the yarn-absorbing port, and a yarn-hanging plate with a hook-shaped structure at one end that rotates around the other end. During rotation, the yarn-hanging plate passes through the yarn-absorbing port and finally rotates to the tail yarn groove of the empty bobbin on the black roller.

[0004] However, in the aforementioned existing automatic yarn-forming control system for spinning after bobbin change, during the yarn-forming process, when the yarn guide plate rotates the yarn path to the tail yarn groove of the empty bobbin held by the clamping plate on the bobbin frame, the first hook-shaped structure passes through the tail yarn groove first, and then the yarn between the two hook-shaped structures gets stuck in the tail yarn groove. At this time, the yarn guide plate is in position, and the yarn path is divided into two paths. The first path of yarn comes out from the original bobbin, passes through the second hook-shaped structure to the tail yarn groove, and the second path of yarn starts from the tail yarn groove and passes through the first hook-shaped structure to the yarn suction port. The yarn ends that fall off from the first path of yarn are prone to fall into and get tangled on the roller shaft of the friction roller, thus affecting the normal winding operation. In severe cases, it can even cause the device to jam, forcing production to stop and reducing production efficiency.

[0005] In view of this, it is necessary to improve the existing automatic spinning head control system for changing bobbins in order to solve the above problems. Summary of the Invention

[0044] The present invention is described in detail below with reference to the embodiments shown in the accompanying drawings. It should be noted that these embodiments are not intended to limit the present invention. Any equivalent changes or substitutions in functions, methods, or structures made by those skilled in the art based on these embodiments shall fall within the protection scope of the present invention.

[0045] It should be particularly noted that in the following embodiments, the term "vertical direction" refers to a direction perpendicular to the horizon or the horizontal line, as Figure 1 the direction shown by the Z-axis. The term "lateral direction" refers to the direction parallel to the horizon or the horizontal line, as Figure 1 the direction shown by the Y-axis. The term "longitudinal direction" refers to the direction parallel to the horizon or the horizontal line and perpendicular to the lateral direction, as Figure 1 the direction shown by the X-axis. The terms "upstream side" and "downstream side" are both referenced to the yarn feeding path.

[0046] Please refer to Figures 1 to 15 to see a specific embodiment of the automatic doffing and anti-winding device and textile equipment disclosed by the present invention. The automatic doffing and anti-winding device 100 disclosed in this embodiment is used for winding yarn. Compared with the spinning doffing automatic piecing control system in the prior art, the automatic doffing and anti-winding device 100 is provided with a shielding plate 19 on the outer side of the end of the roller shaft 61 extending out of the friction roller 6. The roller shaft 61 is covered by the shielding plate 19, and the shielding plate 19, the chuck 72 with the doff cutting part 722, and the yarn hooking device 4 are arranged on the same side of the friction roller 6 along the axial direction (the direction shown by the axis M of the friction roller 6) and vertically aligned. Therefore, during the yarn hooking process of the yarn hooking device 4, the shielding plate 19 can intercept the yarn end that is cut off by the doff cutting part 722, preventing the yarn from approaching and winding on the roller shaft 61, so as to avoid shutdown of the automatic doffing and anti-winding device 100 due to winding problems and ensure production continuity.

[0047] Referring to Figures 1 to 5 in this embodiment, the automatic doffing and anti-winding device 100 includes a traversing device 5, a friction roller 6, and a winding device 7 which are sequentially arranged along the yarn feeding path, and is arranged on the front side of the friction roller 6 (i.e., Figure 1The yarn hanging device 4 in the direction indicated by the double arrow, and a roller shaft 61 axially penetrating the friction roller 6; the winding device 7 comprises: a cradle 71, a pair of chuck plates 72 oppositely arranged on the cradle 71 for clamping the bobbin 300, wherein one chuck plate 72 is provided with a tail yarn cutting portion 722; a shielding plate 19 is arranged outside one end of the roller shaft 61 extending out of the friction roller 6, so that the roller shaft 61 is shielded by the shielding plate 19, the shielding plate 19, the chuck plate 72 with the tail yarn cutting portion 722 and the yarn hanging device 4 are formed on the same side of the friction roller 6 along the axial direction and aligned vertically. The traversing device 5, the friction roller 6 and the winding device 7 are precisely aligned vertically, so as to ensure the smoothness of the yarn feeding path, avoid extra vibration caused by misplaced arrangement, and ensure the uniformity of yarn winding and the quality of finished products. The winding device 7 is responsible for clamping the bobbin 300, and makes the circumferential surface of the bobbin 300 abut against the circumferential surface of the friction roller 6. The friction roller 6 drives the bobbin 300 to rotate through the friction force generated by direct contact with the bobbin 300. The traversing device 5 drives the yarn to perform high-speed reciprocating motion along the length direction of the friction roller 6, and the yarn passes between the bobbin 300 and the friction roller 6, so that the yarn is wound on the bobbin 300 at a certain cross angle. The chuck plate 72 can rotate freely around its own center (or Figure 12 the axis C of the chuck plate 72) relative to the cradle 71. The bobbin 300 is clamped between the pair of oppositely arranged chuck plates 72. At least one chuck plate 72 is configured to be movable along the direction indicated by the axis C, so that the bobbin 300 can be installed between or removed from the chuck plates 72. The tail yarn cutting portion 722 is arranged on the outer back side of the chuck plate 72, and is used for cutting the yarn hooked by the yarn hanging device 4.

[0048] In the prior art, during the doffing and threading process of the automatic spinning doffing threading control system, the dropped yarn end of the first yarn easily falls into and winds around the roller shaft of the friction roller, thereby affecting normal winding operation, and in severe cases, it may also cause the device to seize, forcing production interruption and reducing production efficiency. In the present application, the shielding plate 19 is arranged outside one end of the roller shaft 61 extending out of the friction roller 6, and the outer side of the axial extending end of the roller shaft 61 is directly shielded by the shielding plate 19 to play a role of physical isolation. Moreover, the shielding plate 19, the chuck plate 72 with the tail yarn cutting portion 722 and the yarn hanging device 4 are arranged on the same side along the axial direction of the friction roller 6 and aligned vertically. After the tail yarn cutting portion 722 cuts the yarn hooked by the yarn hanging device 4 during yarn hanging, the shielding plate 19 blocks the dropped yarn end of the yarn, prevents the yarn from contacting and winding on the roller shaft 61, avoids the shutdown of the automatic doffing anti-winding device 100 due to maintenance of winding problems, and ensures production continuity.

[0049] Refer to Figure 3 and Figure 5As shown, the shielding plate 19 is axially adjacent to but not in contact with the friction roller 6. This allows the shielding plate 19 to maximally prevent yarn ends falling off the yarn from contacting the roller shaft 61, and avoid yarn from winding on the roller shaft 61. Furthermore, a necessary gap is left between the shielding plate 19 and the friction roller 6 to accommodate micro-vibration of the shielding plate 19, and avoid unnecessary frictional wear or mechanical interference caused by direct contact between the shielding plate 19 and the friction roller 6.

[0050] Referring Figure 1 and Figure 2 shown in the figures, the automatic doffing anti-winding device 100 further comprises a bearing mechanism 10; the bearing mechanism 10 comprises: a first cross beam 12 and a second cross beam 13 which are arranged in parallel along a transverse direction and are respectively used for mounting the friction roller 6 and a winding device 7, and a support part 11 arranged on the first cross beam 12 and used for mounting a traversing device 5; the friction roller 6, the traversing device 5 and the winding device 7 are aligned in a vertical direction, and the first cross beam 12 and the second cross beam 13 are separated from each other. The traversing device 5 is stably mounted through the support part 11, so as to ensure stable operation of the traversing device 5. Since the friction roller 6 and the winding device 7 generate vibration effects during winding, in order to reduce the occurrence of resonance, in this embodiment, by mounting the friction roller 6 and the winding device 7 respectively on the first cross beam 12 and the second cross beam 13 which are separated from each other and arranged in parallel, there is no direct physical contact or rigid connection between the first cross beam 12 and the second cross beam 13, thereby blocking the vibration transmission path between the friction roller 6 and the winding device 7, reducing the occurrence of resonance, improving the operation performance of the automatic doffing anti-winding device 100, thus effectively preventing structural damage and stress failure of the automatic doffing anti-winding device 100, and prolonging the service life and improving the operation stability of the automatic doffing anti-winding device 100. Meanwhile, through the technical solution of separating the first cross beam 12 from the second cross beam 13 and independently connecting them to the frame 1, the technical problems existing in the prior art that adopts an integral winding table to mount the winding device 7 and the friction roller 6, including large profile weight, extremely high manufacturing difficulty and prone to overall deformation, are reduced. Therefore, it is beneficial to improve the overall rigidity and operation stability of the textile equipment 1000 that comprises the automatic doffing anti-winding device 100 and has hundreds of winding positions, and is beneficial to reduce the noise generated during operation of the textile equipment 1000.

[0051] Referring Figures 2 to 4 shown in the figure, the support part 11 comprises: a plurality of support plates 111 arranged at intervals along the transverse direction, a supporting plate 112 arranged at the top of the support plates 111 and extending toward the friction roller 6, and an adapter block 116 arranged on the supporting plate 112 and connected to the shielding plate 19. The plurality of support plates 111 arranged at intervals along the transverse direction ensures the structural strength of the support part 11 and improves the stability of supporting the traversing device 5. The supporting plate 112 extends toward the friction roller 6, and the shielding plate 19 is connected with the supporting plate 112 through the adapter block 116, so as to ensure the stability of the shielding plate 19 and prevent the shielding plate 19 from contacting the roller shaft 61 due to vibration.

[0052] Reference Figure 1 shown, the automatic doffing anti-winding device 100 further comprises: a full bobbin bin 8 arranged at the rear side of the winding device 7 (i.e., in Figure 1 direction shown by arrow x1) connected to the winding device 7, and an empty bobbin bin 9 vertically correspondingly arranged above the winding device 7 for supplying bobbins 300 to the winding device 7; the carrying mechanism 10 further comprises: a third cross beam 14 and a fourth cross beam 15 which are transversely arranged in parallel and are respectively equipped with the full bobbin bin 8 and the empty bobbin bin 9; the first cross beam 12, the second cross beam 13, the third cross beam 14 and the fourth cross beam 15 are parallel to each other and are located at different heights. The third cross beam 14 and the fourth cross beam 15 are respectively equipped with the full bobbin bin 8 and the empty bobbin bin 9, and the first cross beam 12, the second cross beam 13, the third cross beam 14 and the fourth cross beam 15 remain transversely parallel and are distributed at different heights, so as to meet the installation requirements of different components such as the full bobbin bin 8 and the empty bobbin bin 9, ensure that different components such as the full bobbin bin 8 and the empty bobbin bin 9 work at the most appropriate positions and under the most appropriate conditions, reduce space waste, ensure smooth docking of each component, improve production efficiency and the compactness of the overall structure.

[0053] It should be noted that the first cross beam 12, the second cross beam 13, the third cross beam 14 and the fourth cross beam 15 are all made of high-strength aluminum alloy material, which reduces the overall weight of the automatic doffing anti-winding device 100 by utilizing its characteristics of light weight and high strength, and ensures the stability of the friction roller 6 and the winding device 7 during operation. The supporting part 11 can be made of metal material or engineering plastic. In this embodiment, the supporting part 11 is preferably made of engineering plastic, such as reinforced nylon, polycarbonate, etc. Since the vibration generated by the traversing device 5 during operation is small, engineering plastic can effectively absorb and dissipate the micro-vibration generated during the operation of the traversing device 5 due to its unique damping performance; and compared with metal materials, engineering plastic produces lower noise when subjected to vibration, which can significantly reduce vibration, thereby creating a quieter working environment.

[0054] Reference Figures 1 to 3 and Figure 6 shown, the automatic doffing anti-winding device 100 further comprises: a yarn hooking device 4, a yarn suction device 2 and a yarn guiding device 30 which are arranged on the supporting part 11 and sequentially formed at the front side of the traversing device 5, and a yarn cutting device 3 which is arranged on the supporting part 11 and formed between the friction roller 6 and the yarn suction device 2. After the yarn 200 passes through the yarn guiding device 30, the yarn 200 passes through the traversing device 5 and is finally wound onto the bobbin 300. The traversing device 5 drives the yarn 200 along the length direction of the friction roller 6 (e.g., Figure 6reciprocates at a high speed in the direction shown by the Y axis), under the common constraint of the yarn guide device 30 and the traversing device 5, the area covered by the movement track of the yarn 200 between the yarn guide device 30 and the traversing device 5 forms a triangular area 201, and the plane where the movement track of the yarn 200 between the yarn guide device 30 and the traversing device 5 is located forms a traversing plane 202. The yarn suction device 2 and the yarn cutting device 3 are arranged within the triangular area 201, and the yarn hooking device 4 is arranged outside the triangular area 201. The automatic doffing anti-winding device 100 further comprises: a control element box 20 arranged at the front side of the traversing device 5. A controller (not shown) for controlling the operation of the above components such as the traversing device 5 and the friction roller 6 is arranged in the control element box 20, so as to ensure the automation and precise control of the whole yarn processing process. The carrying mechanism 10 further comprises an integrated frame 16 for mounting the control element box 20.

[0055] Refer to Figures 1 to 3 and Figure 6 , as shown in the figures, when the bobbin 300 completes winding, the yarn suction device 2 is started. Since the yarn suction device 2 and the yarn cutting device 3 are arranged within the triangular area 201, when the traversing device 5 drives the yarn to move toward the yarn suction device 2, the yarn suction device 2 guides the yarn to move downward, so that the yarn position is lower than the traversing plane 202. Then the yarn is introduced into the yarn cutting device 3 to be cut under the drive of the traversing device 5, and meanwhile the yarn suction device 2 sucks the broken yarn; the winding device 7 guides the fully wound yarn spindle (not shown) into the full package bin 8, and then the empty package bin 9 conveys the bobbin 300 to the winding device 7 for clamping, and then the winding device 7 drives the bobbin 300 to abut against the friction roller 6 (refer to Figure 2 for the bobbin 300 and the friction roller 6 therein), and the bobbin 300 is driven to rotate under the rotational drive of the friction roller 6; after the bobbin change is completed, the yarn hooking device 4 moves along Figure 2 rotates in the direction shown by the arrow b1 therein, the yarn hooking device 4 enters the triangular area 201 during rotation and catches the yarn sucked by the yarn suction device 2 when passing the yarn suction device 2. The yarn hooking device 4 finally guides the yarn to move to the winding device 7, the yarn is wound onto the bobbin end 301 by the winding device 7, and the yarn caught by the yarn hooking device 4 is cut, so that the yarn is divided into two paths: the first path of yarn (not shown) comes out from the original yarn bobbin (not shown) and passes through the yarn guide device 30 and the yarn hooking device 4 to the bobbin end 301, and the second path of yarn (not shown) is the part from the yarn hooking device 4 to the yarn suction device 2. The blocking plate 19 blocks the yarn end dropped from the first path of yarn from contacting the roller shaft 61, so as to prevent the first path of yarn from winding on the roller shaft 61, and enable the first path of yarn to be smoothly wound onto the bobbin end 301. The yarn suction device 2 is closed after sucking the second path of yarn, the yarn hooking device 4 pauses slightly at the bobbin end 301 to allow the bobbin 300 to reserve enough tail yarn, and then the yarn hooking device 4 moves along Figure 2rotate reversely back in the direction shown by arrow b2 for resetting. During the reverse rotation of the yarn hooking device 4, the yarn hooking device 4 can press down the position of the first yarn, so that the first yarn moves down to the traversing plane 202. Since the traversing device 5 is also located on the traversing plane 202, when the yarn hooking device 4 passes the traversing device 5, the first yarn can be captured by the traversing device 5 and separated from the yarn hooking device 4. Then, the traversing device 5 drives the first yarn to perform high-speed reciprocating movement along the length direction of the friction roller 6, and the first yarn passes between the package 300 and the friction roller 6, so that the first yarn is wound onto the package 300 at a certain cross angle.

[0056] Referring to Figures 2 to 5 , the automatic doffing and anti-winding device 100 further comprises at least two bearing blocks 62 which are arranged on the first cross beam 12 and support the roller shaft 61 to rotate, and a driving motor which drives the roller shaft 61 to rotate. The roller shaft 61 is driven by the driving motor (such as a stepping motor and a servo motor). The friction roller 6 is arranged parallel to the package 300. In a winding working state, the circumferential surface of the package 300 abuts against the circumferential surface of the friction roller 6, and under the action of friction force therebetween, the rotation of the friction roller 6 drives the package 300 to rotate. The yarn passes between the package 300 and the friction roller 6 and is wound onto the package 300.

[0057] Referring to Figure 1 , Figure 11 and Figure 12 , a cradle 71 is hinged to a second cross beam 13, and a yarn hooking groove 721 is formed on the inner side of a chuck 72 provided with a tail yarn cutting part 722; the winding device 7 comprises a first driving cylinder 73 hinged to the second cross beam 13 to drive the cradle 71 to move between a first position and a second position. A section of the cradle 71 hinged to the second cross beam 13 is configured as a rotating end (not marked), the opposite end of the cradle 71 relative to the rotating end is an open end (not marked), the chuck 72 is arranged at the open end, and the chuck 72 can rotate freely around its own center (or Figure 12 the axis C of the chuck 72) freely rotate. The yarn hooking groove 721 is formed at the circumferential edge of the chuck 72, and the yarn hooking groove 721 is used for hooking the yarn when the yarn hooking device 4 delivers the yarn to the vicinity of the chuck 72 before the start of yarn winding, so as to wind the yarn onto the package. One end of the package close to the chuck 72 with the yarn hooking groove 721 is configured as a tail yarn预留 end 301.

[0058] Referring to Figure 1 and Figure 2 and Figure 11 and Figure 12 , when the winding of the package 300 is completed, the first driving cylinder 73 drives the cradle 71 to rotate around Figure 12 the central axis D and rotate in the direction shown by d1, so as to drive the spindle to move away from the friction roller 6 until the cradle 71 moves to the first position (refer to Figure 12 middle cradle 71), then the chuck 72 releases the spindle, so as to guide the spindle into the full bobbin bin 8; subsequently, the empty bobbin bin 9 conveys the bobbin 300 to the open end of the cradle 71 and clamps it by the chuck 72, and the first drive cylinder 73 drives the cradle 71 to rotate around Figure 12 the central axis D in the direction shown by d2, so as to drive the bobbin 300 to move close to the friction roller 6 until the cradle 71 moves to the second position (see Figure 3 the cradle 71 herein), so that the circumferential surface of the bobbin 300 abuts against the circumferential surface of the friction roller 6 (see Figure 2 the bobbin 300 and the friction roller 6 herein), the bobbin 300 is driven to rotate under the rotation drive of the friction roller 6, and the chuck 72 rotates together with the bobbin 300; after doffing is completed, the yarn hooking device 4 rotates along Figure 2 the direction shown by arrow b1, the yarn hooking device 4 enters the triangular area 201 during rotation and hooks the yarn sucked by the yarn sucking device 2 when passing the yarn sucking device 2. Finally, the yarn hooking device 4 guides the yarn to the chuck 72 having a yarn hooking groove 721, the chuck 72 drives the yarn hooking groove 721 to hook the yarn during rotation, so as to wind the yarn onto the end of the bobbin (i.e., the trailing yarn reserved end 301), and at the same time cuts the yarn hooked by the yarn hooking device 4 through the trailing yarn cutting part 722, so that the yarn is divided into two paths. The first path of yarn comes out from the original yarn bobbin, passes through the yarn guiding device 30 and the yarn hooking device 4 to the trailing yarn reserved end 301, and the second path of yarn is the part from the yarn hooking device 4 to the yarn sucking device 2. The shielding plate 19 blocks the yarn head dropped from the first path of yarn from contacting the roller shaft 61, preventing the first path of yarn from winding on the roller shaft 61, so that the first path of yarn can be smoothly wound onto the trailing yarn reserved end 301. The yarn sucking device 2 is closed after sucking the second path of yarn, the first path of yarn is wound onto the trailing yarn reserved end 301, the yarn hooking device 4 pauses for a short time at the trailing yarn reserved end 301 to allow the bobbin 300 to reserve enough trailing yarn, and then the yarn hooking device 4 rotates back along Figure 2 the direction shown by arrow b2 to return and reset. During the reverse rotation of the yarn hooking device 4, the yarn hooking device 4 can press down the position of the first path of yarn, so that the first path of yarn moves down to the traverse plane 202. Since the traverse device 5 is also located on the traverse plane 202, when the yarn hooking device 4 passes the traverse device 5, the first path of yarn can be captured by the traverse device 5 and separated from the yarn hooking device 4. Then the traverse device 5 drives the first path of yarn to perform high-speed reciprocating movement along the length direction of the friction roller 6, and the first path of yarn passes between the bobbin 300 and the friction roller 6, so as to wind the first path of yarn onto the bobbin 300 at a certain crossing angle.

[0059] See Figure 2 , Figure 7 and Figure 8As shown, the yarn hooking device 4 comprises: a yarn hooking base 41, a yarn hooking arm 42 arranged on the yarn hooking base 41, a rotating shaft 43 continuously penetrating the yarn hooking base 41 and the yarn hooking arm 42, wherein the yarn hooking arm 42 is rotatably connected to the yarn hooking arm 42 through the rotating shaft 43, a first yarn hooking hook 422 and a second yarn hooking hook 423 with opposite hook head directions are formed at the free end of the yarn hooking arm 42 away from the rotating shaft 43, a third driving cylinder 44 arranged on the yarn hooking base 41 for driving the yarn hooking arm 42 to rotate, a protruding part 421 formed by protruding from one end of the yarn hooking arm 42 penetrated by the rotating shaft 43, a coil spring 45 with two ends respectively connected to the protruding part 421 and a cylinder shaft 441 of the third driving cylinder 44, the coil spring 45 is wound around the protruding part 421, and a first torsion spring (not shown) arranged between the yarn hooking arm 42 and the yarn hooking base 41 for driving the yarn hooking arm 42 to reset. The groove depth of the first yarn hooking hook 422 is less than that of the second yarn hooking hook 423, and the distance between the first yarn hooking hook 422 and the rotating shaft 43 is less than the distance between the second yarn hooking hook 423 and the rotating shaft 43.

[0060] Referring Figure 2 , Figure 7 and Figure 8 , after the bobbin change is completed, the third driving cylinder 44 drives the cylinder shaft 441 to move along Figure 8 in the direction indicated by arrow y1, the cylinder shaft 441 pulls the coil spring 45 to drive the protruding part 421 and the yarn hooking arm 42 to rotate along Figure 2 the direction indicated by arrow b1, the first torsion spring undergoes compression deformation during the rotation of the yarn hooking arm 42, the yarn hooking arm 42 rotates into the triangular area 201, and when passing the yarn sucking device 2, hooks the yarn sucked by the yarn sucking device 2 through the first yarn hooking hook 422 and the second yarn hooking hook 423, so as to drive the yarn to rotate together with the yarn hooking arm 42 until the yarn hooking arm 42 rotates to the yarn hooking position (referring to Figure 3 the yarn hooking arm 42 therein), so as to guide the yarn to the chuck 72 with the yarn hooking groove 721, at this time, the first yarn hooking hook 422 is located at the front side of the chuck 72 (that is, the Figure 3 direction indicated by arrow x2 therein), and the second yarn hooking hook 423 is located at the right side of the chuck 72 (that is, the Figure 3in the direction indicated by the arrow y2), so that the chuck 72 can drive the yarn hooking groove 721 to hook the yarn between the first yarn hanging hook 422 and the second yarn hanging hook 423 during rotation, so that the yarn is wound around the tail yarn reserve end 301 and forms a tail yarn. At the same time, the yarn between the first yarn hanging hook 422 and the second yarn hanging hook 423 is cut off by the tail yarn cutting portion 722, so that the yarn is divided into two paths. The first path of yarn comes out from the original yarn bobbin (not shown), passes through the yarn guide device 30 and the second yarn hanging hook 423 to the end of the bobbin. The second path of yarn is the part from the first yarn hanging hook 422 to the yarn suction device 2. The shielding plate 19 blocks the yarn end falling from the first path of yarn from contacting the roller shaft 61, so as to prevent the first path of yarn from winding on the roller shaft 61, so that the first path of yarn can be smoothly wound onto the tail yarn reserve end 301. The yarn suction device 2 is closed after sucking in the second path of yarn, the first path of yarn is wound at the tail yarn reserve end 301, and the yarn hanging arm 42 pauses slightly at the tail yarn reserve end 301 to allow the bobbin to reserve a sufficient amount of tail yarn. Then, the acting force generated by the first torsion spring restoring its deformation makes the yarn hanging arm 42 move along Figure 2 the direction indicated by the arrow b2 to rotate back and reset. During the reverse rotation of the yarn hanging arm 42, the first path of yarn is clamped in the groove of the second yarn hanging hook 423, so that the second yarn hanging hook 423 can press down the position of the first path of yarn to move the first path of yarn down to the traverse plane 202. Since the traverse device 5 is also located on the traverse plane 202, when the yarn hanging arm 42 passes the traverse device 5, the first path of yarn can be captured by the traverse device 5 and separated from the second yarn hanging hook 423, so that the traverse device 5 drives the first path of yarn to perform high-speed reciprocating movement along the length direction of the friction roller 6. The first path of yarn passes between the bobbin 300 and the friction roller 6, so that the first path of yarn is wound on the bobbin 300 at a certain crossing angle, and the yarn hanging arm 42 resets to the Figure 2 standby position as shown.

[0061] Refer to Figure 7 and Figure 8 as shown, the yarn hooking device 4 further includes: a protective cover 47 covered outside the coil spring 45, one end of the rotating shaft 43 extending out of the yarn hanging arm 42 is connected to the protective cover 47, an adjusting screw 48 arranged on the base, and a shock-absorbing rubber 49 arranged at the free end of the adjusting screw 48. By controlling the lateral position of the adjusting screw 48, the rotation angle of the yarn hanging arm 42 can be limited, preventing the yarn hanging arm 42 from excessively rotating and interfering with the winding device 7; the shock-absorbing rubber 49 can effectively reduce impact noise. The protective cover 47 can achieve the functions of dust prevention, foreign matter prevention and preventing yarn from falling in.

[0062] Refer to Figure 4 , Figure 9 and Figure 10As shown, the yarn suction device 2 comprises: a yarn suction seat 23 provided with a yarn suction port 22, a yarn catching plate 24 rotatably connected with the yarn suction seat 23 and covering the yarn suction port 22, a spring 25 disposed at an end of the yarn suction seat 23 opposite to the yarn suction port 22 and clamped between the yarn suction seat 23 and the yarn catching plate 24, an airflow core 26 provided inside the yarn suction seat 23 and communicated with the yarn suction port 22, a yarn outlet connector 27 partially penetrating the yarn suction seat 23 and communicated with the airflow core 26, and a piston rod 28 provided inside the yarn suction seat 23 and formed between the yarn suction port 22 and the spring 25; the yarn suction seat 23 is formed with a compressed air cavity 231 surrounding an outer periphery of the airflow core 26, the yarn suction seat 23 is formed with a compressed air inlet 232 communicated with the compressed air cavity 231, the yarn suction seat 23 is formed with a pressure cavity 233 surrounding an outer side of the piston rod 28 and communicated with the compressed air cavity 231, and the airflow core 26 is formed with a plurality of inclined elongated holes 261 which communicate the compressed air cavity 231 with the yarn outlet connector 27 and extend downward. The yarn suction seat 23 is formed with a compressed air outlet 234 communicated with the pressure cavity 233. A plurality of the inclined elongated holes 261 are uniformly distributed, the inclined elongated holes 261 form an included angle of 30° with a horizontal direction, lower portions of the inclined elongated holes 261 are communicated with the yarn outlet connector 27, and upper portions of the inclined elongated holes 261 are communicated with the compressed air cavity 231. A bottom of the yarn outlet connector 27 is communicated with a yarn suction pipe 21, and the yarn suction pipe 21 is connected to a waste yarn box (not shown).

[0063] Reference Figure 9 and Figure 10 As shown, when a bobbin completes winding, the yarn suction device 2 is activated, compressed air enters the compressed air inlet 232 through a pipe (not shown), and the compressed air enters the compressed air cavity 231, part of the compressed air passes through the airflow core 26 and directly enters the pressure cavity 233 to push the piston rod 28 upward (as Figure 10 in the direction indicated by arrow s1) to move, and then the piston rod 28 pushes the yarn catching plate 24 to rotate relative to the yarn suction seat 23, so that the free end of the yarn catching plate 24 covering the yarn suction port 22 is lifted to form as shown in Figure 10The yarn catching plate 24a shown therein opens the yarn suction port 22, meanwhile, one end of the yarn catching plate 24 connected to the spring 25 moves downward and compresses the spring 25 until the free end of the yarn catching plate 24 is positioned higher than the traverse plane 202. When the traverse device 5 drives the yarn to move toward the yarn suction device 2, the yarn catching plate 24a guides the yarn to move downward, so that the yarn is positioned lower than the traverse plane 202, and then the yarn is introduced into the yarn cutting device 3 to be cut under the driving of the traverse device 5; meanwhile, since the yarn suction port 22 is in an open state and communicates with the outside air, another part of the compressed air in the compressed air chamber 231 enters the inclined long hole 261, and enters the yarn outlet connector 27 through the inclined long hole 261, so that the compressed air forms a high-speed rotating airflow in the yarn outlet connector 27, and pushes the air in the channel of the yarn outlet connector 27 to move downward to the yarn suction pipe 21, and the air flow rate in the yarn outlet connector 27 is much higher than the air flow rate at the upper part of the airflow core 26, thereby forming a negative pressure area in the upper part of the airflow core 26 and the channel of the yarn suction port 22. Since the yarn suction port 22 is in an open state, the external atmospheric pressure and the negative pressure inside the yarn suction port 22 form a large pressure difference, and the external airflow enters the airflow core 26, the yarn outlet connector 27 and then the yarn suction pipe 21 from the yarn suction port 22, so that the broken yarn cut by the yarn cutting device 3 is sucked into the yarn suction pipe 21.

[0064] After the bobbin changing is completed, the third driving cylinder 44 drives the yarn hooking arm 42 along Figure 2 the direction shown by arrow b1 to rotate, the yarn hooking arm 42 enters the triangular area 201 during rotation, and when passing the yarn suction device 2, hooks the yarn sucked by the yarn suction port 22 through the first yarn hooking hook 422 and the second yarn hooking hook 423, so as to drive the yarn to rotate together with the yarn hooking arm 42 until the yarn hooking arm 42 rotates to the yarn hooking position (this state is not shown), thereby guiding the yarn to the chuck 72 with the yarn hooking groove 721; after the yarn is divided into two paths, the yarn suction port 22 sucks the second path of yarn, so that the second path of yarn finally enters the waste yarn box for recovery through the yarn suction pipe 21, then the delivery of compressed air to the compressed air inlet 232 is stopped, an external pipeline (not shown) extracts the compressed air in the pressure chamber 233 through the compressed air outlet 234, so as to drive the piston rod 28 to move downward, meanwhile the spring 25 releases elastic potential energy to drive the yarn catching plate 24 to rotate relative to the yarn suction seat 23 for resetting, until the free end of the yarn catching plate 24 is positioned lower than the traverse plane 202 and covers the yarn suction port 22, so as to close the yarn suction device 2 and complete the yarn suction process.

[0065] Reference Figure 1 and Figure 2As shown, the thread cutting device 3 is configured as a blade device 31 formed between the yarn sucking device 2 and the friction roller 6 for cutting the yarn path and assisting doffing, and the edge position of the blade device 31 is lower than the traverse plane 202. When the traversing device 5 drives the yarn to move toward the yarn sucking device 2, the yarn is guided by the free end of the yarn catching plate 24 to move downward, so that the yarn position is lower than the traverse plane 202. Then, driven by the traversing device 5, the yarn is introduced into the blade device 31 and enters the cutting edge to cut the yarn off.

[0066] Refer to Figure 1 and Figure 2 and Figure 5 As shown, the traversing device 5 comprises: a driving motor (not shown), a driving pulley 52 controlled by the driving motor, two driven pulleys 53 arranged along the length direction of the friction roller 6, a synchronous belt 54 erected between the driving pulley 52 and the driven pulleys 53, and a traverse yarn guide 55 configured on the synchronous belt 54, which reciprocates along the length direction of the friction roller 6 within a set stroke range. The two driven pulleys 53 and the driving pulley 52 are arranged in a triangle, and the traverse yarn guide 55 is mounted on a portion of the synchronous belt 54 parallel to the friction roller 6. The driving motor is a motor capable of alternating forward and reverse operation. The driving motor drives the driving pulley 52 to rotate clockwise and counterclockwise, the rotating force of the driving pulley 52 is transmitted to the synchronous belt 54, and the traverse yarn guide 55 fixed to the synchronous belt 54 reciprocates between the two driven pulleys 53 within the set stroke range, winds the yarn onto a bobbin at a certain crossing angle, and the yarn reciprocates within the stroke of the traverse yarn guide 55 and overlaps each other to form a yarn package.

[0067] After a certain length of tail yarn is reserved, the yarn hanging arm 42 moves along Figure 2 the direction shown by arrow b2 to rotate backward and reset. During the backward rotation of the yarn hanging arm 42, the yarn is clamped in the groove of the second yarn hanging hook 423, so that the second yarn hanging hook 423 can press down the position of the yarn, and move the first yarn path down to the traverse plane 202. Since the traverse yarn guide 55 is also located on the traverse plane 202, when the yarn hanging arm 42 passes the traverse yarn guide 55, the yarn can be caught by the traverse yarn guide 55 and separated from the second yarn hanging hook 423, so that the traverse yarn guide 55 can drive the yarn to perform high-speed reciprocating movement along the length direction of the friction roller 6.

[0068] Refer to Figure 1 , Figure 13 and Figure 14As shown, the empty winding chamber 9 includes: a frame-shaped support 91 connected to the fourth crossbeam 15; the frame-shaped support 91 extends inward along its longitudinal side walls to form a guide plate 92 for guiding the rolling of the drum; a fourth drive cylinder 93 disposed at the bottom of the guide plate 92; a drum handle 94 disposed at the top of the frame-shaped support 91 to limit excessive rolling of the drum; a rotating arm 95 rotatably connected to the frame-shaped support 91 opposite to the guide plate 92 and controlled to rotate by the fourth drive cylinder 93; a drum handle 96 disposed at the top of the rotating arm 95 and extending obliquely towards the direction of the drum handle 94; and a drum handle 97 disposed at the end of the rotating arm 95 near the guide plate 92. Multiple drums are arranged in a single layer within the empty winding chamber 9. The guide plate 92 extends downward from the end of the empty winding chamber 9 opposite to the rotating arm 95 toward the drum handle 97, so that the drum maintains a tendency to roll toward the drum handle 97. The drum handle 97 is located on the front side of the guide plate 92 (e.g., ...). Figure 14 (In the direction indicated by the middle arrow x2), the free end of the cylinder handle 97 rests against the bottom surface of the guide plate 92, allowing the cylinder to roll smoothly from the guide plate 92 into the cylinder handle 97. The two longitudinal sidewalls of the frame-shaped support 91 extend laterally inward and inclined toward the cylinder handle 97 to form positioning plates 911 for guiding the cylinder to be centered with the frame-shaped support 91. The distance between the upper ends of the two positioning plates 911 is slightly greater than the length of the cylinder, and the distance between the lower ends of the two positioning plates 911 is slightly less than the length of the cylinder. During the process of the cylinder rolling from the guide plate 92 to the cylinder handle 97, when the cylinder passes the positioning plate 911, the cylinder can move axially along the positioning plate 911 to naturally adjust its own center position, so that the cylinder remains centered and aligned with the frame-shaped support 91 after falling into the cylinder handle 97, ensuring that subsequent cylinders can be accurately loaded into the clamp 72.

[0069] The free end of the lower handle 96 is bent inward to form a front finger 961. Positioning pieces 962 are constructed at both ends of the lower handle 96 laterally to constrain the cylinder between the lower handle 96 and the cylinder handle 97. Because the guide plate 92 is inclined towards the cylinder handle 97, the cylinder is guided by the guide plate 92 to roll towards the cylinder handle 97. When the first cylinder (not shown) in the empty cylinder 9 rolls out of the guide plate 92 and lands on the cylinder handle 97, the positioning pieces 962 prevent the first cylinder from continuing to roll and keep it stationary. Together with the front finger 961, the first cylinder is clamped between the lower handle 96 and the cylinder handle 97. The other cylinders in the empty cylinder 9 are arranged behind the first cylinder (e.g., ...). Figure 13 (In the direction indicated by the middle arrow x1). A rotating shaft 952 is configured at one end of the rotating arm 95 connected to the handpiece 97. A second torsion spring (not shown) is sleeved on the outside of the rotating shaft 952 to generate an elastic force on the handpiece 97. The second torsion spring drives the two handpieces 97 to rotate around the axis F and maintain their position along... Figure 13a tendency to rotate in the direction indicated by arrow f1, so as to drive the upper bobbin arm 97 to press the bobbin upward against the inner side of the lower bobbin arm 96, thereby clamping the bobbin between the lower bobbin arm 96 and the upper bobbin arm 97.

[0070] A rearward extending lug 98 is provided at the connection between the frame-shaped bracket 91 and the rotating arm 95, the rearward extending lug 98 is formed on the side of the frame-shaped bracket 91 where the fourth driving cylinder 93 is disposed, the rotating arm 95 penetrates the rearward extending lug 98 and is formed with a gear 951 inside the rearward extending lug 98; the free end of the driving shaft 931 of the fourth driving cylinder 93 is formed with a rack 932 extending into the rearward extending lug 98 and meshing with the gear 951. The gear 951 is injection-molded on the rotating arm 95 and integrated with the rotating arm 95. The free end of the driving shaft 931 of the fourth driving cylinder 93 is provided with a thread structure (not marked) for mounting the rack 932. The rack 932 is preferably an elongated nylon part, and the rack 932 is provided with a copper nut for cooperating with the thread structure at the free end of the driving shaft 931.

[0071] The guide plate 92 is formed with a connecting plate 912 for the fourth driving cylinder 93 to be hinged to, and the bottom of the fourth driving cylinder 93 is hinged on the connecting plate 912 by means of a pin shaft. One of the guide plates 92 is provided with a bobbin detection device 99, which is configured to give an alarm when there is no bobbin, so as to block the delivery of the bobbin to the chuck 72 and subsequent actions. The top of the upper bobbin arm 94 is formed with a tongue-shaped structure 941, the tongue-shaped structure 941 is inserted into the long slot (not marked) at the top of the frame-shaped bracket 91, and after being inserted into the long slot, the tongue-shaped structure 941 is bent by an external tool (not shown), so as to prevent the upper bobbin arm 94 from falling off the long slot. Since the width of the long slot is greater than the thickness of the upper bobbin arm 94, there is a certain allowance in the long slot for the upper bobbin arm 94 to perform a certain translation and rotation at a certain angle.

[0072] Ref Figure 1 , Figure 13 and Figure 14 , when the cradle 71 moves to the first position and waits for gripping a new bobbin, a first bobbin is clamped between the upper bobbin arm 97 and the lower bobbin arm 96, the fourth driving cylinder 93 drives the driving shaft 931 to move along Figure 13 the direction indicated by arrow x2 to extend out, driving the rack 932 to move synchronously, the rack 932 meshes with the gear 951 to drive the rotating arm 95 to rotate around axis E and along Figure 13 the direction indicated by arrow e1, the rotating arm 95 drives the lower bobbin arm 96 and the upper bobbin arm 97 to rotate synchronously, and through the elastic force exerted on the upper bobbin arm 97 by the second torsion spring, the upper bobbin arm 97 is kept along Figure 13a tendency to rotate in the direction shown by arrow f1 in the figure, so that the upper bobbin handler 97 and the lower bobbin handler 96 can clamp the bobbin tightly, to drive the bobbin to rotate synchronously with the rotating arm 95. When the upper bobbin handler 97 rotates to the tube feeding position, the first bobbin clamped by the upper bobbin handler 97 and the lower bobbin handler 96 coincides with the center of the chuck 72 of the cradle 71, that is, the axis of the bobbin (not shown) coincides with the axis C of the chuck 72, and then the first bobbin is clamped by the chuck 72; after the first bobbin clamped by the upper bobbin handler 97 and the lower bobbin handler 96 is unloaded, the fourth driving cylinder 93 drives the rotating arm 95 along Figure 13 the direction shown by arrow e1 in the figure to rotate and reset, and due to the action of the second torsion spring, the upper bobbin handler 97 rotates along Figure 13 the direction shown by arrow f1 in the figure until the free end of the upper bobbin handler 97 abuts against the bottom surface of the guide plate 92.

[0073] When the upper bobbin handler 97 and the lower bobbin handler 96 clamp the first bobbin out of the empty winding bin 9, the subsequent bobbins start to roll forward (in the direction Figure 14 shown by arrow x2 in the figure), and meanwhile, the upper bobbin 94 also descends when the lower bobbin handler 96 descends. When the tongue-shaped structure 941 contacts the upper surface of the frame-shaped support 91, the upper bobbin 94 rotates around the contact point and finally stops rotating under the blocking of the top surface of the frame-shaped support 91. At this time, the bent portion 942 on the upper bobbin 94 exactly presses against the forward-rolling bobbin, thereby restricting the subsequent bobbins from rolling forward, so as to avoid a failure in the front, and when the first bobbin is not unloaded and needs to return to the empty winding bin 9 again, no interference influence will occur. The fourth driving cylinder 93 drives the rotating arm 95 along Figure 13 the direction shown by arrow e1 in the figure to rotate and reset, meanwhile, the lower bobbin handler 96 moves synchronously with the rotating arm 95 and jacks up the upper bobbin 94. Finally, when the upper bobbin 94 abuts against the top surface of the frame-shaped support 91, due to the lifting of the upper bobbin 94, the subsequent bobbin rolls down onto the upper bobbin handler 97 and is stopped by the blocking of the positioning piece 962 on the lower bobbin handler 96, the whole rotation stops, waiting for the next feeding.

[0074] Referring to Figure 1 , Figure 11 and Figure 12 shown in the figure, the full winding bin 8 comprises: a mounting frame 84, a spindle rail 81 arranged on the mounting frame 84, a rotating fork 82 vertically arranged on the spindle rail 81, the rotating fork 82 is provided with a rotating shaft 85 which forms a rotational connection with the spindle rail 81, and a third torsion spring (not shown) arranged on the rotating shaft 85 for driving the rotating fork 82 to gather inward, and the spindle rail 81 is provided with a spindle detection device 83. When the cradle 71 moves to the first position, the chuck 72 then releases the spindle, and the spindle is released and falls onto the spindle rail 81. When the first spindle rolls on the spindle rail 81, the rotating fork 82a and the rotating fork 82b respectively rotate along Figure 12rotates in the direction shown by arrows p1 and p2 to open outward, so that the first spindle enters the first bin (not shown), then the rotating fork 82a and the rotating fork 82b rotate reversely and close, the second spindle is stored in the second bin (not shown), and a spindle detection device 83 is formed on the second bin to provide a full bin signal or a bobbin storage success signal.

[0075] One end of the spindle rail 81 close to the cradle 71 in the longitudinal direction is higher than the other end formed with a protrusion (not marked) at the edge, the plane where the spindle rail 81 is located forms a set angle with the horizontal plane, and the set angle can be 4° or 5°. This is conducive to assisting the rolling and positioning of the spindle by using gravity, ensuring that the spindle can smoothly slide into the spindle rail 81 during the transfer process, and reducing the risk of jamming or rolling. The first spindle is blocked by the protrusion to stop rolling, so that the first spindle is stored in the first bin; after the rotating fork 82 rotates reversely and closes, the second spindle is blocked by the rotating fork 82 to stop rolling, so that the second spindle is stored in the second bin.

[0076] The winding device 7 further comprises: a guide seat 711 disposed inside the cradle 71; when the cradle 71 is at the first position, the spindle rail 81 extends to the cradle 71 and is connected with the guide seat 711 to guide the spindle to roll into the spindle rail 81. In the operation of the winding device 7, when the cradle 71 is at the specific first position, the guide seat 711 connected with the spindle rail 81 can guide the spindle to accurately roll into the spindle rail 81 when the chuck 72 releases the spindle, ensuring seamless connection in the transfer process.

[0077] Reference Figure 11 and Figure 12 As shown, the winding device 7 further comprises: a damping plate 75 disposed on the cradle 71 and rotating along with the cradle 71, an connecting rod 76 disposed at the free end of the damping plate 75, and a second driving cylinder 77 hinged to the bottom of the second cross beam 13 and connected with the connecting rod 76. The moment generated by the second driving cylinder 77 is opposite to the moment generated by the bobbin 300 due to its own weight, ensuring that the pressing force exerted by the bobbin 300 on the friction roller 6 remains relatively constant during the winding process, so as to maintain stable yarn tension and improve winding quality.

[0078] Reference Figure 11 and Figure 12 As shown, the winding device 7 further comprises: a pin seat 78 disposed at the bottom of the second cross beam 13, the damping plate 75 continuously penetrates the second cross beam 13 and the pin seat 78, the damping plate 75 is formed with a brake slot 751 along the rotation track formed by rotation along with the cradle 71, and a friction damping member 79 disposed on the pin seat 78 and penetrating the brake slot 751 to clamp the damping plate 75. When along Figure 12Rotate the cradle 71 along the direction indicated by d2 about the central axis D, force the circumferential surface of the bobbin 300 to abut against the circumferential surface of the friction roller 6, and make the bobbin 300 start winding yarn, so that during the winding process of the bobbin 300, the cradle 71 skillfully utilizes the friction damping 79 of the aforementioned clamping damping plate 75, and isolates, absorbs and consumes the vibration generated by the bobbin 300 during the winding process through the friction damping 79, thereby effectively absorbing and consuming the vibration energy generated when the bobbin 300 rotates, greatly improving the stability of yarn winding and reducing yarn quality problems caused by vibration. A pulse sensor 74 is arranged at the position where the cradle 71 is aligned with the chuck 72, and is configured to feed back the real-time rotation speed of the yarn bobbin.

[0079] Referring to Figures 2 to 3 and Figure 5 as shown, the support portion 11 further comprises: a guide rail 113 arranged at an end of the supporting plate 112 close to the friction roller 6, a limiting block 114 formed on the guide rail 113, wherein the limiting block 114 is configured to limit the moving range of the traversing device 5 driving the yarn, and a cover plate 115 arranged on the supporting plate 112. The guide rail 113 is configured to guide the reciprocating movement of the traversing yarn guide 55, the limiting block 114 is formed inside the driven pulley 53, and the cover plate 115 covers the driving pulley 52 and the synchronous belt 54. A driving motor is mounted on the inner side of the supporting plate 112, a motor shaft of the driving motor penetrates the supporting plate 112 to connect to the driving pulley 52, and the yarn hanging seat 41 is arranged on the supporting plate 112. The guide rail 113 is mounted at the end of the supporting plate 112 close to the friction roller 6, and the guide rail 113 performs accurate guiding on the reciprocating linear movement of the traversing yarn guide 55 to ensure smooth transition of yarn during winding and prevent yarn damage or dislocation. The limiting block 114 is configured to limit the moving range of the traversing yarn guide 55, prevent the traversing yarn guide 55 from exceeding a preset track, ensure safe and reliable movement, and at the same time help maintain the stability of yarn tension. The driving motor transmits power to the traversing yarn guide 55 through the driving pulley 52 and the synchronous belt 54, so as to realize precise control of the traversing yarn guide 55. The cover plate 115 covers the driving pulley 52 and the synchronous belt 54, protects transmission components such as the driving pulley 52 and the synchronous belt 54 from intrusion of dust and foreign matters, and improves the cleanliness and safety of the traversing device 5. The yarn hanging seat 41 is also arranged on the supporting plate 112, which ensures cooperative work with the traversing yarn guide 55 and other components, and ensures smoothness and stability during yarn introduction.

[0080] It should be noted that the empty winding bin 9, the full winding bin 8 and the control element box 20 are all made of thin sheet metal materials. Compared with other heavy structural materials, thin sheet metal products have a lower natural frequency, and are all isolated from the friction roller 6 and the winding device 7, which blocks the vibration transmission path of the friction roller 6 and the winding device 7, thereby reducing the resonance phenomenon and further reducing the noise problem caused by resonance.
