Description

[Technical Field]

[0001] This invention relates to a yarn processing method, specifically a winding method for a fully automatic winding machine, belonging to the field of yarn production technology. [Background Technology]

[0002] As is well known, a winding machine is a production device that turns a large roll of yarn into several smaller rolls of yarn, so that the smaller rolls of yarn can meet specific usage requirements, such as being used as sewing thread, embroidery thread, or braiding thread.

[0003] Due to their usage characteristics, sewing thread and embroidery thread often have small yarn bobbins. Therefore, the bobbins need to be changed frequently during the bobbin-turning process, and the yarn needs to be cut before changing the bobbins. Manually cutting the yarn and then manually changing the bobbins not only requires a large amount of labor and increases the labor intensity of workers, but also reduces the production efficiency of the equipment.

[0004] The yarn guiding mechanism is an important component of the winding machine. It drives the yarn to move back and forth, ensuring that the yarn is evenly distributed across the yarn tube. Existing yarn guiding mechanisms, such as those shown in Chinese Invention Patent No. 202022452102.0, use a motor 81 to drive the yarn guiding head 85 to move back and forth. This mechanism has a complex overall structure, is difficult to assemble, has poor reliability, and one motor can only drive one yarn guiding head, resulting in low working efficiency.

[0005] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative winding method for a fully automatic winding machine to overcome the defects in the prior art. [Summary of the Invention]

[0006] To address the aforementioned problems, the present invention aims to provide a winding method for a fully automatic winding machine, which has stable performance, high winding efficiency, and is fully automated.

The system holds a yarn tube, and an active winding mechanism drives the yarn tube to rotate, thereby winding the unwound yarn from the large roll of raw yarn onto the yarn tube; the yarn guiding mechanism is located on one side of the active winding mechanism and can reciprocate radially along the yarn tube to ensure the yarn fills the yarn tube; the tube clamping mechanism is located below the active winding mechanism and can grip the yarn tube; the scissor mechanism is located below the passive top-end mechanism and can cut the yarn; the vibrating plate is connected to the tube feeding mechanism and can feed the yarn tube to the tube feeding mechanism; the tube feeding mechanism can load several yarn tubes and can transport the yarn tubes between the active winding mechanism and the passive top-end mechanism.

[0009] 1) The yarn is unwound from the large roll of raw yarn and passes through the tensioner, yarn guide roller, yarn probe and yarn guide mechanism in sequence to reach the yarn tube; at this time, the active winding mechanism starts and drives the yarn tube to rotate, and the yarn guide mechanism reciprocates to guide the yarn, so that the yarn is continuously wound into the yarn tube until the yarn fills the body of the yarn tube.

[0010] 2) The clamping mechanism rises and grips the yarn tube, while the passive top mechanism retracts to release the yarn tube; then, the clamping mechanism descends and rotates downward, causing the yarn tube to move towards one side of the scissor mechanism.

[0011] 3) The tube feeding mechanism starts, which delivers a new yarn tube between the active winding mechanism and the passive mandrel mechanism; then the passive mandrel mechanism extends, so that the yarn tube abuts between the active winding mechanism and the passive mandrel mechanism, and the yarn is clamped between the passive mandrel mechanism and the new yarn tube.

[0012] 4) The scissor mechanism extends and starts to cut the yarn; the cut yarn is still held by the passive top mechanism and the yarn tube, while the scissor mechanism resets; then, the tube clamping mechanism rotates further downward, releases the yarn tube, and resets.

Detailed Implementation Methods

[0042] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 13 As shown, this is a fully automatic winding machine of the present invention, which is assembled from several parts, including a frame 1, a yarn rack 2, an active winding mechanism 3, a yarn guiding mechanism 4, a passive top head mechanism 5, a tube clamping mechanism 6, a scissor mechanism 7, a vibrating plate 8, and a tube feeding mechanism 9, all mounted on the frame 1.

[0043] The frame 1 is the skeleton of the entire winding machine, which is supported on the ground, and various mechanisms are installed on it.

[0044] The yarn rack 2 is located on top of the frame 1, and several large rolls of yarn 10 are placed on it. In this embodiment, there are 4 rolls of yarn 10 to correspond to 4 workstations. The yarn rack 2 is equipped with a tensioner 21, a yarn guide roller 22, and a yarn detector 23 in sequence. The yarn 11 unloaded from the yarn rack 2 has its tension adjusted by the tensioner 21, and then passes through the yarn guide roller 22 and the yarn detector 23 in sequence. The yarn detector 23 detects whether the yarn 11 is broken.

[0045] The active winding mechanism 3 and the passive top-end mechanism 5 are arranged opposite to each other and are provided in several groups. In this embodiment, four groups are provided. The yarn tube 12 is held between the active winding mechanism 3 and the passive top-end mechanism 5. The yarn tube 12 is driven to rotate by the rotation of the active winding mechanism 3, thereby winding the yarn 11 unwound from the large roll of raw yarn 10 onto the yarn tube 12.

[0046] The yarn guiding mechanism 4 is located on one side of the active winding mechanism 3. It can reciprocate radially along the yarn tube 12, thereby driving the yarn 11 to move and cover the yarn tube 12 with the yarn 11. Specifically, the yarn guiding mechanism 4 is assembled from several parts, including a yarn guiding bracket 41, a vertical plate 42, a yarn guiding motor 43, a transmission shaft 44, a wire shifting rod clamp 45, a wire shifting rod 46, and a yarn guiding head 47.

[0047] The yarn guide bracket 41 serves as the base for the entire yarn guide mechanism 4, enabling the yarn guide mechanism 4 to be manufactured modularly. Two upright plates 42 are provided and welded parallel to each other onto the yarn guide bracket 41, and are vertically connected to the yarn guide bracket 41.

[0048] The yarn guiding motor 43 is mounted on one of the upright plates 42. In this embodiment, the yarn guiding motor 43 is located between two upright plates 42, thereby making full use of the space between the two upright plates 42 and making the entire yarn guiding mechanism structure compact. A main synchronous pulley 431 is connected to the yarn guiding motor 43, and the main synchronous pulley 431 is driven to rotate by the yarn guiding motor 43.

[0049] The drive shaft 44 is pivotally connected to and supported on two upright plates 42, with driven pulleys I441 and II442 respectively mounted at its two ends. A synchronous belt I481 is fitted onto the main synchronous pulley 431 and the driven pulley I441. The yarn guiding motor 43 sequentially drives the main synchronous pulley 431, the synchronous belt I481, and the driven pulley I441, while the driven pulley I441 is linked to the drive shaft 44, which in turn drives the driven pulley II442.

[0050] Furthermore, a driven pulley III 421 is installed on another vertical plate 42 where the yarn guide motor 43 is not installed. A synchronous belt II 482 is fitted onto the driven pulleys II 442 and III 421, so that the driven pulley II 442 sequentially drives the synchronous belt II 482 and the driven pulley III 421. In this embodiment, the main synchronous pulley 431, driven pulley I 441, driven pulley II 442, and driven pulley III 421 are arranged in a 2*2 matrix, which makes the arrangement neat and ensures that the synchronous belts I 481 and II 482 have the same length, thus having good versatility.

[0051] The lead screw clamp 45 is fixed to the synchronous belt I481 and the synchronous belt II482 respectively, and can be driven by the synchronous belt I481 and the synchronous belt II482 respectively. The lead screw 46 is fixed to the lead screw clamp 45 and is driven by the lead screw clamp 45 to move back and forth in the front and back direction.

[0052] To limit the left-right and up-down positions of the displacement screw 46, a V-shaped support roller 461 is provided below the displacement screw 46, and a pressure roller 462 is provided above it. The V-shaped support roller 461 and the pressure roller 462 are arranged opposite to each other and clamp the displacement screw 46. Specifically, the V-shaped support roller 461 can clamp the displacement screw 46, so that the displacement screw 46 can be limited to the left, right and down positions; the pressure roller 462 presses down on the displacement screw 46 to prevent the displacement screw 46 from moving upward.

[0053] Two parallel yarn guide rods 46 are provided, each perpendicular to and passing through the yarn guide bracket 41, and respectively positioned on the outer side of the two upright plates 42 for a reasonable layout. The two yarn guide rods 46 are connected by a connecting rod 463 to prevent them from rotating.

[0054] The yarn guide head 47 can hook the yarn 11 and is installed at one end of the yarn guide rod 46. In this embodiment, each yarn guide rod 46 is provided with two yarn guide heads 47, so that the two yarn guide rods 46 drive the four yarn guide heads 47 synchronously and make the four yarn guide heads 47 move synchronously, which greatly improves the efficiency of yarn guiding.

[0055] The working principle of the yarn guiding mechanism 4 is as follows: The yarn guiding motor 43 rotates in both directions, driving the main synchronous pulley 431 in sequence. The main synchronous pulley 431 then sequentially links the synchronous belt I481, the driven pulley I441, the transmission shaft 44, the driven pulley II442, the synchronous belt II482, and the driven pulley III421. The above transmission is achieved through the synchronous belt and pulleys, which provides smooth transmission, reliable performance, and long service life. The reciprocating movement of the synchronous belts I481 and II482 drives the yarn guide screw clamp 45 to reciprocate. The yarn guide screw clamp 45 drives the yarn guide screw 46 to reciprocate back and forth, and the yarn guide head 47 guides the yarn through the yarn guide screw 46. By controlling the number of rotations of the yarn guiding motor 43, the reciprocating stroke of the synchronous belts I481 and II482 can be adjusted, thus allowing the stroke of the yarn guide head 47 to be adjusted arbitrarily to meet different yarn guiding requirements.

[0056] Furthermore, the active winding mechanism 3 and the yarn guiding mechanism 4 are mounted on the same yarn guiding bracket 41, which consists of an active winding motor 31 and several active winding rollers 32. The active winding motor 31 is mounted on the yarn guiding bracket 41, and it drives all the active winding rollers 32 to rotate via a transmission belt 33. The active winding rollers 32 abut against the side of the yarn tube 12, and drive the yarn tube 12 to rotate by the rotation of the active winding rollers 32.

[0057] The clamping mechanism 6 is located below the active winding mechanism 3. It can grip the wound yarn tube 12, causing the yarn tube 12 to disengage from the active winding mechanism 3 and the passive top mechanism 5, and rotate towards the scissor mechanism 7. After the scissor mechanism 7 cuts the yarn, the clamping mechanism 6 releases the yarn tube 12. The clamping mechanism 6 is prior art, so it will not be described in detail here.

[0058] The scissor mechanism 7 is located below the passive top mechanism 5 and can cut the yarn 11. Specifically, the scissor mechanism 7 consists of several parts, including a mounting base 71, a scissor telescopic cylinder 72, a scissor seat 73, a fixed blade 74, a movable blade 75, a scissor connecting rod 76, and a scissor cylinder 77.

[0059] The mounting base 71 is fixed to the frame 1 of the winding machine, so that the entire scissor mechanism is mounted on the frame 1.

[0060] The scissor telescopic cylinder 72 is installed inside the mounting base 71. It connects to and pushes the scissor seat 73, allowing the scissor mechanism to retract when not cutting the yarn 11, thus preventing the scissors from accidentally cutting the yarn 11 or interfering with other mechanisms of the winding machine (such as the tube clamping mechanism 6). Specifically, the scissor telescopic cylinder 72 includes a cylinder rod 721, which extends vertically out of the mounting base 71 and connects to the scissor seat 73. The cylinder rod 721 pushes the scissor seat 73 to extend or retract. A guide rod 722 is provided on each side of the cylinder rod 721. One end of the guide rod 722 is connected to the scissor seat 73 and supported on the mounting base 71 by a linear bearing 723. The guide rod 722 limits the direction of movement of the scissor seat 73, preventing it from rotating.

[0061] The fixed blade 74 is fixedly mounted on the scissor holder 73 and moves in conjunction with the scissor holder 73. The movable blade 75 is pivotally connected to the scissor holder 73, can rotate relative to the fixed blade 74, and cooperates with the fixed blade 74 to cut the yarn 11. That is, when the movable blade 75 and the fixed blade 74 engage, the yarn 11 is cut.

[0062] The scissor cylinder 77 is installed on one side of the scissor seat 73. It is connected to and drives the scissor connecting rod 76 to extend and retract, thereby providing power for the shearing action of the scissor mechanism. Since only one scissor cylinder 77 is needed to drive it, the structure of the scissor mechanism is simple and the cost is low.

[0063] The scissor linkage 76 is pivotally connected to the movable blade 75 and can drive the movable blade 75 to open and close. Specifically, the movable blade 75 is provided with a waist hole 751, and the scissor linkage 76 is provided with a pin 761, which is received in the waist hole 751 and pushes the movable blade 75 to open and close. Furthermore, the bottom of the scissor seat 73 is provided with several guide blocks 731, and the scissor linkage 76 passes through the guide blocks 731 to limit the movement direction of the scissor linkage 76.

[0064] Several movable blades 75 are provided, all of which are simultaneously driven by the same scissor linkage 76. Because the scissor linkage 76 drives multiple movable blades 75 simultaneously, the wire cutting efficiency is high, the actions are synchronized, and the labor intensity of the workers is greatly reduced. In this embodiment, four movable blades 75 are specifically provided and arranged at equal intervals; each movable blade 75 corresponds to one fixed blade 74.

[0065] The working principle of the scissor mechanism 7 is as follows: When it is necessary to cut the yarn 11, the scissor telescopic cylinder 72 drives the cylinder rod 721, causing the cylinder rod 721 to extend. The cylinder rod 721 drives the scissor seat 73 and components such as the fixed blade 74 and the movable blade 75 mounted on the scissor seat 73. During the extension process, the extension and retraction direction of the scissor mechanism is limited by the guide rod 722. After the scissor mechanism extends, the yarn 11 enters between the fixed blade 74 and the movable blade 75. Then, the scissor cylinder 77 starts and pulls the scissor connecting rod 76. The scissor connecting rod 76 links all the movable blades 75, causing the movable blades 75 to close relative to the fixed blade 74, thereby cutting the yarn 11.

[0066] Furthermore, the passive top-mounting mechanism 5 and the scissor mechanism 7 are mounted on the same mounting base 71, and are composed of several parts including a passive top-mounting cylinder 51, a top plate 52, top rods 53, and a top head 54. The passive top-mounting cylinder 51 is mounted on the mounting base 71 and connects to and drives the top plate 52. Several top rods 53 are provided, extending out of the mounting base 71. Each top rod 53 is connected to and driven by the top plate 52, allowing one passive top-mounting cylinder 51 to synchronously drive all the top rods 53. One end of each top rod 53 is pivotally connected to the top head 54, which abuts against the side of the yarn tube 12. A return spring 55 is sleeved on each top rod 53, and the return spring 55 abuts against the top plate 52, thereby resetting the top plate 52.

[0067] The vibratory feeder 8 is connected to the tube feeding mechanism 9, which straightens the yarn tube 12 and feeds it to the tube feeding mechanism 9. The vibratory feeder 8 is a commercially available product and will not be described in detail here.

[0068] The tube feeding mechanism 9 can load several empty yarn tubes 12 and can transport the yarn tubes 12 between the active winding mechanism 3 and the passive top mechanism 5. Specifically, the tube feeding mechanism 9 consists of several parts, including a base plate 92, a guide rail 93, a slider 94, a tube holder 95, a lead screw 96, a conveying motor 97, a hopper 98, and a cylinder 199.

[0069] The base plate 92 is mounted on the frame 1. In this embodiment, a bearing seat 91 is mounted on the frame 1, and one end of the base plate 92 is pivotally connected to the frame 1 via the bearing seat 91, thereby allowing the base plate 92 to rotate relative to the frame 1. A limiting block 921 is provided at the other end of the base plate 92. The limiting block 921 is mounted on the frame 1 and abuts against the side of the base plate 92 to prevent the base plate 92 from deflecting during rotation.

[0070] Furthermore, the frame 1 is provided with a compression spring seat 13, and a compression spring 14 is provided inside the compression spring seat 13. The compression spring 14 abuts against the bottom of the base plate 92 to support the base plate 92, and works together with the limiting block 921 to keep the base plate 92 in a horizontal state.

[0071] The guide rail 93 is fixed on the base plate 92; the slider 94 cooperates with the guide rail 93 and slides along the guide rail 93.

[0072] The connector 95 is mounted on the slider 94 and driven by the slider 94. The connector 95 is provided with a plurality of yarn tube positioning grooves 951, each yarn tube positioning groove 951 being able to accommodate one yarn tube 12. In this embodiment, four yarn tube positioning grooves 951 are provided, thereby enabling the simultaneous delivery of four yarn tubes 12, and the yarn tube positioning grooves 951 can position the yarn tubes 12 to prevent them from rolling.

[0073] The lead screw 96 is pivotally connected to the base plate 92 via a lead screw seat 961; the lead screw 96 and the slider 94 are screwed together, enabling the lead screw 96 to drive the slider 94 to reciprocate along the guide rail 93. The conveying motor 97 is mounted on the base plate 92, on the same side as the bearing seat 91. The conveying motor 97 can drive the lead screw 96 to rotate. Specifically, the conveying motor 97 and the lead screw 96 are connected by a synchronous pulley 971 and a synchronous belt 972.

[0074] The hopper 98 is mounted on the frame 1, located at one end of the guide rail 93, and can hold several yarn tubes 12. The hopper 98 is vertically arranged, with clamping arms 981 on both sides. The yarn tubes 12 are clamped between the clamping arms 981 to prevent them from falling and to ensure that the yarn tubes 12 are stacked one on top of the other. A yarn tube sensing probe 982 is installed on the hopper 98, which can detect whether there are yarn tubes 12 in the hopper 98, so as to replenish the yarn tubes 12 in time and ensure that each yarn tube positioning slot 951 of the connector 95 can receive one yarn tube 12.

[0075] The cylinder I99 is installed at the bottom of one side of the hopper 98, and includes a mandrel 991 that can be inserted into the bottommost yarn tube 12 to prevent the yarn tube 12 from falling out.

[0076] A cylinder II15 is mounted on the frame 1; the cylinder II15 is connected to one end of the base plate 92, and the cylinder II15 and the bearing seat 91 are located at different ends of the base plate 92. The cylinder II15 can drive the base plate 92 to rotate around the bearing seat 91, causing the connecting pipe seat 95 to tilt.

[0077] The working principle of the tube feeding mechanism 9 is as follows:

[0078] 1) The yarn tube sensing probe 982 detects whether there is a yarn tube 12 in the hopper 98. If there is no yarn tube 12, the vibratory feeder 8 is activated to automatically add a yarn tube 12 into the hopper 98 for use. At this time, the core rod 991 of the cylinder 199 is inserted into the bottommost yarn tube 12 to prevent the yarn tube 12 from falling out.

[0079] 2) When the winding machine needs a new yarn tube 12, the conveyor motor 97 starts, which drives the lead screw 96 to rotate. The rotation of the lead screw 96 drives the slider 94 to move along the guide rail 93. The slider 94 moves in conjunction with the connecting pipe seat 95, causing the connecting pipe seat 95 to extend. At this time, the core rod 991 of the cylinder 199 retracts, and the bottommost yarn tube 12 falls onto the connecting pipe seat 95, but is still constrained by the hopper 98.

[0080] 3) The conveying motor 97 continuously drives the connector seat 95. When the yarn tube positioning groove 951 of the connector seat 95 passes the bottom yarn tube 12, the yarn tube 12 is installed into the yarn tube positioning groove 951 until one yarn tube 12 is installed in each of the four yarn tube positioning grooves 951.

[0081] 4) After the winding machine grabs the four yarn tubes 12 on the connector seat 95, cylinder II 15 retracts, causing the base plate 92 to rotate downwards by an angle. This disengages the yarn tubes 12 from the connector seat 95, preventing them from getting stuck on the yarn tubes 12 when the connector seat 95 retracts. Simultaneously, the conveyor motor 97 rotates in the opposite direction, resetting the connector seat 95. After the connector seat 95 resets, cylinder II 15 also resets, and the compression spring 14 keeps the base plate 92 in a horizontal position.

[0082] The winding method of the fully automatic winding machine of the present invention is as follows:

[0083] 1) The yarn 11 is unwound from the large roll of raw yarn 10 and passes through the tensioner 21, the yarn guide roller 22, the yarn probe 23 and the yarn guide mechanism 4 in sequence to reach the yarn tube 12; at this time, the active winding mechanism 3 is started and drives the yarn tube 12 to rotate, and the yarn guide mechanism 4 reciprocates to guide the yarn, so that the yarn 11 is continuously wound into the yarn tube 12 until the yarn 11 covers the body of the yarn tube 12.

[0084] 2) The clamping mechanism 6 rises and grips the yarn tube 12, while the passive top mechanism 5 retracts to release the yarn tube 12; then, the clamping mechanism 6 descends and rotates downward, causing the yarn tube 12 to move towards one side of the scissor mechanism 7.

[0085] 3) The tube feeding mechanism 9 is started, which delivers a new yarn tube 12 between the active winding mechanism 3 and the passive top mechanism 5; then the passive top mechanism 5 extends, so that the yarn tube 12 abuts between the active winding mechanism 3 and the passive top mechanism 5, and the yarn 11 is clamped between the passive top mechanism 5 and the new yarn tube 12.

[0086] 4) The scissor mechanism 7 extends and starts to cut the yarn 11; the cut yarn 11 is still held by the passive top mechanism 5 and the yarn tube 12, while the scissor mechanism 7 resets; then, the clamping mechanism 6 rotates further downward, releases the yarn tube 12 and resets.

[0087] 5) The active winding mechanism 3 and the yarn guiding mechanism 4 restart and repeat the actions of steps 1) to 4) to achieve fully automatic continuous production.

[0088] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
