At least two first wheels 101 are arranged at the bottom of the first base 100, so that the first base 100 can be moved. A plurality of first spindles 103 are sleeved on the mounting seats 105 on one side of the first bracket 102, and the first spindles 103 are wound with first yarns. Preferably, the one side can be the front side of the first bracket 102 in the yarn racking device of this embodiment. A plurality of second spindles 104 are sleeved on the other side of the first bracket 102 through the mounting seats 105, and the second spindles 104 are wound with second yarns. The arrangement of the first spindles 103 and the second spindles 104 is preferably, and the other side can be the back side of the first bracket 102 in the yarn racking device of this embodiment. The first bracket 102 can be rotated as needed to change the direction of the first spindle 103 and the second spindle 104 relative to the yarn frame mechanism 2. The number of the first spindle 103 and the second spindle 104 installed is not limited. A plurality of them can be set according to different working conditions and the size of the first bracket 102. The present invention does not impose any further restrictions on this.

[0057] The specific structure of the creel mechanism 2 is described in detail below:

[0058] Please refer to Figures 1 to 5 The yarn rack mechanism 2 has an isolation component and a guide and limit component. The isolation component is used to prevent the first yarn and / or the second yarn from being entangled. The guide and limit component is used to confine the first yarn and / or the second yarn to a fixed area and guide the yarn.

[0059] For details, please continue to refer to Figures 1 to 5 The creel mechanism 2 further comprises a movable base frame 201, wherein the bottom of the base frame 201 is connected to at least two second wheels 200, so that the base frame 201 can be moved by the second wheels 200. The isolation assembly is movably arranged on the base frame 201, so that the spacing of the isolation assembly relative to the guide limit assembly is adjustable.

[0060] For details, please refer to Figure 1 , Figure 3 and Figure 5 The isolation assembly includes a first frame 203, and a plurality of first plates 2030 are connected to the first frame 203, wherein two vertical brackets of the first frame 203 are connected to each of the first plates 2030. Similarly, a plurality of first holes 2010 are provided on each of the vertical brackets, and the first plates 2030 can be connected to the first holes 2010 through screws 207, and nuts 2011 can be connected to the screws 207, so that the first plates 2030 are fixed to the first frame 203. After the screws 207 are removed, the height position of the first plates 2030 can be adjusted according to the first holes 2010 at different heights.

[0061] For further information, please continue to refer to Figure 1 , Figure 3 and Figure 5 A plurality of yarn spacing columns 209 are connected between the upper and lower adjacent first plates 2030, and each yarn spacing column 209 between each upper and lower adjacent row is staggered, so that when the first yarn or the second yarn is introduced into the isolation component, each yarn can be isolated by the yarn spacing column 209. When the first spindle 103 or the second spindle 104 swings during high-speed yarn drawing, adjacent first yarns or adjacent second yarns are prevented from being entangled with each other or knotted, so as to improve work efficiency.

[0062] For further information, please continue to refer to Figure 1 , Figure 2 and Figure 5The guide and limit assembly includes a second frame 206, and a plurality of second plates 2060 are connected to the second frame 206. Similarly, a plurality of first holes 2010 are provided on two vertical brackets of the second plate 2060, and the second plate 2060 can be fixed to the first holes 2010 by screws 207. At the same time, a nut 2011 can be connected to the screw 207, so that the first plate 2030 is fixed to the second frame 206. After the screw 207 is removed, the height of the second plate 2060 relative to the second frame 206 can also be adjusted.

[0063] For further information, please continue to refer to Figure 1 , Figure 2 and Figure 5 , between the upper and lower adjacent second plates 2060, an annular structure 208 is further provided on each of the second plates 2060, and the first yarn or the second yarn can pass through the annular structure 208. Similarly, the annular structures 208 between each row of upper and lower adjacent ones are arranged in a staggered manner. The annular structure 208 ensures that the first yarn of the first spindle 103 or the second yarn on the second spindle 104 is always confined in the hole of the annular structure 208 during high-speed yarn drawing, so that the first yarn or the second yarn is guided to the subsequent positioning and pressing mechanism.

[0064] Furthermore, the position of each of the yarn spacing columns 209 and the position of each of the annular structures 208 correspond to the position of the first spindle 103 or the second spindle 104 in the spindle mechanism 1. This allows the first yarn in the first spindle 103 and the second yarn in the second spindle 104 on the spindle mechanism 1 to be in the same area when being led out without being bent around other areas.

[0065] For further information, please continue to refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 In order to realize the movability of the isolation assembly, a groove 202 is also provided on the two short brackets of the base frame 201, and a portion of the bottom of the two vertical brackets in the first frame 203 has a clearance fit with the groove 202. Similarly, a fixing plate 2012 is also connected between the two vertical brackets in the first frame 203, and the fixing plate 2012 is in a "T" shape. A first cylinder 205 is also connected to the outside of the base frame 201, and the piston rod of the first cylinder 205 passes through the base frame 201 and is connected to the fixing plate 2012 through the piston 204. When the piston rod of the first cylinder 205 is extended, it can drive the piston 204, the fixing plate 2012 and the first frame 203 to move, thereby causing the two vertical brackets in the first frame 203 to move along the groove 202, so as to realize the position adjustment of the entire isolation assembly relative to the guide limit assembly.

[0066] The specific structure of the switching mechanism 3 is described in detail below:

[0067] Please refer to Figure 6 and Figure 7 The switching mechanism 3 is arranged close to the yarn output direction of the creel mechanism 2, and the switching mechanism 3 is used to change the standard yarn from the first position to the second position.

[0068] For details, please continue to refer to Figure 6 and Figure 7 The switching mechanism 3 includes a bottom plate 305, which is arranged on the surface of a second base 300. The second base 300 is fixed on a plane by bolts 301. A first column 309 for inserting a standard yarn tube 313 is arranged on the bottom plate 305. A movable platform 315 is also provided on the bottom plate 305 near the first column 309.

[0069] For further information, please continue to refer to Figure 6 and Figure 7 The platform 315 is movable by a pneumatic device, which includes a second cylinder 306, a piston rod of which is connected to a portion of a connecting plate 308, and another portion of the connecting plate 308 is connected to the platform 315.

[0070] For further information, please continue to refer to Figure 6 and Figure 7 In order to prevent the platform 315 from moving beyond the stroke, a limit block 302 is further provided on the base plate 305. The limit block 302 is provided close to the first slider 303. When the second cylinder 306 is reset, the first slider 303 abuts against the limit block 302 to ensure that the platform is reset to the first position.

[0071] For further information, please continue to refer to Figure 6 and Figure 7 At least two second columns 310 and a bracket assembly are arranged on the upper surface of the platform 315 , and a first tensioner 314 corresponding to the position of the second column 310 is arranged on the bracket assembly.

[0072] For details, please continue to refer to Figure 6 and Figure 7The second upright column 310 is also used to insert the standard yarn tube 313.

The second bracket 311 is also provided with a yarn guide rod 316.

[0073] The switching mechanism 3 is arranged between the yarn rack mechanism 2 and the positioning and pressing yarn mechanism 400. In addition to changing the standard yarn from the first position to the second position, the switching mechanism 3 is used to embed the standard yarn in the braided belt, and the braided belt is made by extracting a certain length of the first yarn in the first spindle 103 or the second yarn in the second spindle 104, and continuously weaving it through a braiding machine. The braided braided belt is finally put into the dyeing sample machine for dyeing. The dyed braided belt is compared with the dyeing degree of the braided embedded standard yarn to judge the color difference of each spindle yarn. The inspector determines the level of each spindle yarn according to the color difference on the braided belt. Since the standard yarn and the first spindle 103 or the standard yarn and the second spindle 104 are set at different positions when they are continuously woven, when the first spindle 103 is continuously woven and switched to the second spindle 104, or when the second spindle 104 is continuously woven and switched to the first spindle 103, the position of the standard yarn needs to be changed, that is, changed by the switching mechanism 3.

[0074] The specific structure of the fixed position yarn pressing mechanism 400 is described below:

There is a through hole (not shown in the figure) between the yarn embedding seats 7000 for the central rod 702 to pass through. Specifically, the yarn embedding seat 7000 includes two mutually connected round tables, and the connection between the adjacent round tables forms a yarn embedding seam 7003 for the yarn to be embedded and fixed.

[0093] Please refer to Figure 1 In the yarn outlet direction of the first yarn clamping device 6, a yarn storage device 8 and a braiding device 9 are respectively provided, wherein the yarn storage device 8 is used to wind the yarn after the splicing is completed and continuously feed the yarn to the subsequent braiding device 9, and the braiding machine is used to braid the yarn into a cylindrical yarn tape.

[0094] Please refer to Fig.19 In order to achieve yarn separation without the problem of yarns being entangled with each other, a yarn separation bracket 10 is also arranged between the yarn frame mechanism 2 and the yarn pressing and twisting device 5. The yarn separation bracket 10 includes a third base 1000 and a fourth column 1001 vertically connected to the third base 1000.

When all the first yarn threading ceramic rings 10020 on the top yarn threading plate 1002 have passed through, the subsequent yarns are threaded one by one from left to right or from right to left at the second yarn threading ceramic ring 10030, and so on. Finally, all the yarns pulled out from the yarn rack mechanism 2 are evenly arranged in the vertical and horizontal directions, so that the yarns are not easy to interfere with each other, so that the user unit can realize yarn separation without changing the conventional process, and meet the flexible combination of process requirements of different units.

[0096] Accordingly, the present invention also provides a method for splicing yarns using the above-mentioned automatic splicing machine, comprising the following steps:

[0097] S1: Place a plurality of first spindles 103 and second spindles 104. For details, please refer to Figure 1 The first spindle 103 and the second spindle 104 are respectively mounted on the plurality of mounting seats 105 on the first bracket 102 .

[0098] S2: Please refer to Figure 1 , guide out the first yarn on the first spindle 103. Specifically, the operator first passes the first yarn on each first spindle 103 on the spindle mechanism 1 through the isolation component in the creel mechanism 2, wherein the first yarn passes between two adjacent yarn spacing columns 209, and the spacing between each adjacent first yarn is 40mm to 50mm. The first yarn passing through the isolation component needs to pass through the guide limit component. Taking a first yarn as an example, the first yarn passing between two adjacent yarn spacing columns 209 continues to be pulled forward and passes through the hole of the annular structure 208. Please refer to Figure 1 , the first yarn passing through the annular structure 208 is guided to the positioning and pressing yarn mechanism 400.

[0099] For details, please refer to Figure 8 and Fig. 9 The guided first yarn passes through the gap between two adjacent positioning pins 4007 after passing through the yarn pressing rod 4000, wherein the yarn pressing rod 4000 contacts the first yarn and applies a part of pressure to the first yarn (but does not affect the movement of the first yarn), and the yarn is supported on the cross bar 4006 when passing through the adjacent positioning pins 4007, please refer to Fig.16The first yarn passes through the gap between adjacent positioning pins 4007 and is fixed by the second tensioner 401. The first yarn passing through the second tensioner 401 passes between two magnetic sheets 602. The adjacent magnetic sheets 602 are positive and negative ceramic sheets. The first yarn passing through the magnetic sheets 602 passes through the inlaid yarn structure 700 and is embedded in the inlaid yarn seam 7003, so that the first yarn is arranged straight at the yarn guide end of the yarn pressing and twisting device 5.

[0100] S3: Please refer to Fig.15 as well as Fig.16 After all the first yarns are led out, there are still several places between adjacent first yarns where standard yarns need to be inserted so that the first yarns can be embedded in the standard yarns during subsequent twisting. At this time, the standard yarns led out of the first position are pressed and positioned.

[0101] For details, please refer to Figure 6 , Figure 7 , the standard yarn is drawn out from the standard yarn drum 313 and passes through the first tensioner 314, and then passes through the yarn guide port 3161 corresponding to the position of the first tensioner 314, and the standard yarn is always limited to the yarn guide port 3161 through the yarn guide port 3161, and the yarn guide port 3161 is fixed on the yarn guide rod 316, and the standard yarn passing through the yarn guide port 3161 also passes through the yarn pressing rod 4000 and passes through the gap between two adjacent positioning pins 4007 at the corresponding position, and the standard yarn is also supported on the cross bar 4006, and after passing through the gap between the adjacent positioning pins 4007, it is fixed by the second tensioner 401, and the standard yarn passing through the second tensioner 401 passes between two magnetic sheets 602, and the adjacent magnetic sheets 602 are positive and negative ceramic sheets, and the standard yarn passing through the magnetic sheets 602 passes through the yarn embedding structure 700 and is embedded in the yarn embedding seam 7003, so that the standard yarn is arranged straight at the yarn guide end of the yarn pressing and twisting device 5. Please refer to Fig.17 In the twisting process of the first yarn, the standard yarn is distributed between the arranged first yarns. There are three standard yarns in total, and one standard yarn is distributed at the last yarn in the entire row of first yarns.

[0102] S4: One-time splicing, please refer to Figures 10 to 14 When the first yarn and the standard yarn cross over the top of the splicer 508 in the pressure splicing device 5, due to the large spacing between the two adjacent yarns, and the two yarns may not enter the splicing head of the splicer 508, please refer to Figures 10 to 14 The worker inputs a control command in the PLC console 502, the first stepper motor 519 receives the command and controls the first screw rod 504 to rotate, the first screw rod nut 505 moves axially along the first screw rod 504 to drive the movable base 506 to move between the two yarns, please refer to Figures 10 to 14During this process, the thread pushing rod 528 contacts one of the first yarns and pushes one of the first yarns toward the other first yarn (or the first yarn toward the standard yarn), so that the two first yarns (or one first yarn and one standard yarn) are closely adjacent to each other and are located above the splicing head of the splicer 508.

[0103] In order to meet the requirements of splicing two strands of yarn in the splicer 508, please refer to Figures 10 to 14 , the PLC console 502 issues a command, the cylinder 512 is started and its piston drives the movable plate 514 to move downward relative to the vertical plate 525. Since the left and right sides of the movable plate 514 are respectively fixed with the wire pressing plate 511, the wire pressing plate 511 also moves downward. During the downward movement of the wire pressing plate 511, it contacts two first yarns or a first yarn and a standard yarn, and presses them down to the splicing head of the splicer 508.

[0104] like Fig.12 As shown, during the downward movement of the wire pressing plate 511, since one side of the movable plate 514 is fixedly connected to the pressing block mounting plate 529, the pressing block 530 also moves downward along with the movable plate 514. After moving downward, the pressing block 530 contacts the yarn and presses it into the ink cartridge 532 for coloring, thereby realizing the segmented color marking of each section of the yarn, so that the segmented color marking can be seen on the final entire continuous cylindrical braided belt to correspond to the spindles.

[0105] like Figures 8 to 11 As shown, after being in place, the second stepper motor 520 starts working, and completes the rotational twisting (knotting) in sequence through the mechanical transmission of the flange coupling 518, the bearing 517, and the first elastic coupling 516. In this process, the two strands of yarn are mainly untwisted and cut off in the twisting chamber. After the twisting is completed, the yarn pressing action is reset. At the same time, the PLC console 502 controls the first screw nut 505 in the servo slide to advance one station to prepare for the next twisting. After the yarn twisting is completed, the yarn head passes through the yarn holder 510 and then enters the dyeing test weaving machine.

[0106] Please refer to Fig.17 After the last standard yarn is twisted with the first yarn, the yarn pressing and twisting device 5 returns to the starting position with the standard yarn. At this time, the operator connects the first yarn with the standard yarn with the subsequent first second yarn.

[0107] S5, the second yarn on the second spindle 104 is led out and pressed and positioned. Figure 1, turn the spindle mechanism 1 in one direction so that the second spindle 104 faces the creel mechanism 2, and refer to the same method as step S2 to pass each strand of the second yarn on the second spindle 104 through the adjacent yarn spacing column 209 and the annular structure 208, and the guided second yarn passes through the gap between two adjacent positioning pins 4007 after passing through the yarn pressing rod 4000, wherein the yarn pressing rod 4000 contacts the second yarn and applies a part of pressure to the second yarn (but does not affect the movement of the first yarn), and the yarn is supported on the cross bar 4006 when passing through the adjacent positioning pin 4007, please refer to Fig.16 The second yarn passes through the gap between adjacent positioning pins 4007 and is fixed by the second tensioner 401. The first yarn passing through the second tensioner 401 passes between two magnetic sheets 602. The adjacent magnetic sheets 602 are positive and negative ceramic sheets. The second yarn passing through the magnetic sheets 602 passes through the inlaid yarn structure 700 and is embedded in the inlaid yarn seam 7003, so that the second yarn is arranged straight at the yarn guide end of the yarn pressing and twisting device 5.

[0108] S6, export the standard yarn at the second position. For details, please refer to Figure 6 and Figure 7 The second cylinder 306 starts and drives the connecting plate 308 through the piston rod, so that the connecting plate 308 drives the platform 315 to move. Please refer to Figure 6 and Fig.17 The movement of the platform 315 drives the standard yarn tube 313 to move from the first position to the second position. After moving to the second position, the standard yarn is no longer needed to be placed at the original first position, but is replaced by the second yarn. Now the standard yarn is placed at the second position. Specifically, the placement process of the standard yarn is the same as step S3, except that it changes from the first position to the second position. The present invention will not be further elaborated on this.

[0109] S7, secondary splicing, similarly, please refer to Fig.18 When the second yarn and the standard yarn are arranged in a straight line, the yarn pressing and splicing device splices the second yarn with the second yarn, or splices the second yarn with the standard yarn, according to the process of step S5, until all the second yarns are spliced. Figure 1 The second yarn after twisting passes through the yarn storage device 8 together with the standard yarn and enters the weaving device 9 to verify the quality of spinning and dyeing by relying on the standard yarn.
